To help doctors in detecting more than 50 eye diseases, DeepMind will be developing a product to detect sight-threatening conditions from a common eye scan. Deep Mind is an artificial intelligence company based in London and owned by Alphabet.
According to a study that has been published in Nature Medicine, the DeepMind trained artificial intelligence software will be able to detect the eye diseases better than the doctors. The eye scans that use artificial intelligence could be very useful in detecting eye diseases and prevent loss of sight. The technology could detect sight-threatening eye diseases quickly which will ensure that patients do not need to wait in case of urgent treatment.
DeepMind in partnership with London’s Moorfields Eye Hospital and the University College London Institute of Ophthalmology plan to conduct trials based on this technology in 2019.
If they achieve success then DeepMind would go in for a regulator approved product which Moorfields could market in the UK. This would be the first software of Deep Mind AI algorithm that makes use of machine learning in a healthcare product. If they get the approval, then the clinicians at Moorfields would use it free of cost across 30 UK hospitals and clinics for a period of five years.
DeepMind will use its trained artificial intelligence program on 15,000 patients and will use optical coherence tomography (OCT) to detect any signs of eye disease. OCT is an imaging technique that gives 3D images of the rear of the eye by using light waves.
Although OCT scans are used to detect eye diseases, it is difficult for the clinicians to interpret and can be done so only by experts.
On the other hand, the technology adopted by DeepMind will be able to detect eye diseases directly from the OCT scan in a matter of seconds. The patients in urgent need of care can be treated immediately as there is no wastage of time between the scan taken and the treatment to be administered.
The DeepMind AI technology combines two neural networks such as segmentation and classification. In the first analysis, the OCT scan shows the entire eye tissue as well as the features of the disease. The second step analyses the eye tissue image and enables the clinicians with the diagnosis and a recommendation.
The DeepMind trained AI technology will need to undergo trials. If they get regulatory approval, then the technology could be used for different types of eye scanners and not only for the purpose that it was trained at Moorfields.
DeepMind is confident that the trained AI technology could be a ground-breaking path in the diagnosis and treatment of eye diseases.
DeepMind was bought by Google in 2014 and since then they have been expanding into gaming and healthcare. In 2015, they partnered with Royal Free teaching Hospital in London and worked on an app called Streams which alerts the clinicians to acute kidney injury.
DeepMind used machine learning to radiotherapy planning for head and neck cancer in 2016. Deep Mind also used its machine learning to improve the detection of breast cancer.
Do you feel like your time and energy are exhausted by doing keyword research? Google trends can improve your strategy.
Well, the formula for keyword research success is not complicated, but all it requires is smartness and exploring tools to find best keywords. Along with that, you have to make use of some platforms to make some profitable keyword lists.
Now, if you are in the digital marketing field means you’ll undoubtedly come across google trends for your keyword research. But, if you are a starter to this field means you’ll never utilize the full potential of this excellent tool.
So, today I am going to discuss about the google trends platform.
In this post, I’ll cover all the best possible ways to use google trends for keyword research.
if you don’t know about google trends means, don’t worry I’ll explain to you.
Google trends is a free online search tool which allows you to see how often keywords, phrases, and subjects have been searched in Google over a specific period.
You can quickly analyze any keyword search graph over a period of time. This tool is regularly updated, and you can quickly find a lot of best and new keywords from the google trends.
Now after knowing about this tool, most of you might think about how to use this tool right?
When you first come across this tool, you can see what searches are currently trending along with the latest stories and insights with maps. When you scroll down, you can even see what was trending on google by year.
Now, when you enter a keyword, you will get the metrics of that keyword.
In that, most of the people think that the trend curve is the direct and proper representation of search volume over time similar to the Google, keyword planner.
Here the trends graphs will work differently. When you search for a keyword in google trends, it will show you the interest over time graph whereas coming to google keyword planner you’ll get Average monthly search volume.
So, these both results are entirely different.
“ Google trends always adjust the search data to make comparisons between keywords easier. Here every data point is divided by the total searches of geography and time range to compare relative popularity merely”.
“To simply it, the relative popularity is the ratio of a keyword search volume to the sum of all possible queries search volumes”.
After the metrics, the result then gets scaled on a range of 0 to 100 just based on the topic ratio to all the searches.
This google trends tool eliminate repeated search queries from the same id over a short period of time to give accurate results.
Note: Google Trends only shows data for popular and trending terms. Other low volume keywords will be shown as 0.
Ex: Have a look at the google trends graph for the search term “ twitter” over past 12 months
Now, to clearly explain to you how Google trends give its “Interest over time” graph. Let’s assume that i have google date. ( No can have one but let’s pretend)
Let me take the assumption values to explain to you.
Assume: Total monthly search number of google searches is around 10-11 billion.
Assume: Now, Search volume of the query “twitter” in us is 80 million.
|May 2018||June 2018||July 2018|
|Avg total Monthly searches in the USA||10,000,000,000||10,000,000||11,000,000,000|
|Avg twitter monthly search volume in the USA||90,000,000||85,000,000||75,000,000|
Now, these are the example results just to show you how it works. Most of these values are inappropriate and assumed Value.
Until now, I have shared the working mechanism of the google trends. Now, let’s check out the proper ways which are useful in finding out the best keywords.
In this post, I am going to share seven best ideas to use google trends for keyword research. Along with that, I will show how you can refine your searches as well.
If you want to get massive traffic to your website means you have to follow this step. Here in this step, you’ll discover all the seasonal trends, and you’ll create excellent content around that keyword and start promoting to get massive traffic.
Have a glance at the screenshot; you can have a look at the trends of “Raincoats.” These are mostly purchased in the rainy season so you can see an upward graph in rainy seasons. Medium traffic in another season, so google trends is helpful in discovering seasonal trends.
Here is another example, in this report I used a keyword 2018 FIFA world cup. You can see a massive graph when the FIFA world cup is running. After that, you can see the decrease graph.
So, by using this way you can explore the best trending and popular keywords. If you are running a sports website, then make use of the ongoing popular tournaments. But, if you are selling Raincoats as a seasonal business, then you can make use of the google trends to find the time where people are laboriously searching for best raincoats.
When you are trying to create excellent content for your next blog post or your website. Always make sure you checked the topic on Google trends before you start writing it.
By checking the topic, you can get the trends of that keyword. So, it will be useful for you to save your time by not creating content for falling topics.
Usually, when you consider writing about some keyword, you will have multiple options. Choose the best one which is moving upwards or having some decent traffic don’t go with old trends.
Previously there is massive popularity for “spinners,” and it has also touched 100 in google trends interest over time. But since that, it has fallen massively and not even getting minimum traffic.
So, it is always best to shift your focus on upcoming trends rather than going for download trends.
Are you striving to get traffic?
Then why don’t you explore google trends to get untapped keywords for your site? By using google trends “ trending searches” option, you can quickly find lots of search queries which have a significant upward graph in popularity over the past 24 hours.
So, target those keywords to get massive shares and traffic to your site.
Most of you might be wondering why you should be choosing that option right?
Well, let’s assume that you run a sports blog.
You have gone through trending searches on FIFA World Cup.
For Suppose at the time you see FIFA world cup it has already reached the finals stage, you might think that you are too late?
But that’s not too late.
People also search for that term for some days, and you might even get an upward spike after a couple of days as well. After a few days or months, you will again see a downward spike, but that doesn’t matter to you because you have already achieved lots of traffic for that keyword in that small time.
So, it is always best to capitalize on the trending topics. Here you have to remember one thing don’t go for that keyword after a couple weeks or months because you will not get any traffic.
Now, Are you having a long-term blog or website?
Then you can make use of google trends data to get a good amount of traffic.
Whenever you see the google trends for the term “ Oscars”. You can see increased graph at the time of Oscar awards every year.
It is because the Oscars program will take place in March every year. So, you can make use of that google trends data if you have a long term.
Google trends usually let its users reveal untapped queries people also search for in trends when they search for your term.
So, you can make use of them and include them in your keyword listings. Most of the popular brands always do this to improve their chances of buying products.
when people are searching for “Shoes” they also tend to search for “curling shoes” and red bottoms shoes.”
Not only that they also provide some other search related topics and queries which are useful for website owners to know what the searcher is searching for.
Now, by using those keywords, you can simply do your keyword research on tools you generally use. So, by doing keyword research, you will explore even more new keyword ideas for your sie.
Watching is always best when it comes to SEO.
Now, carefully watch google trends “interest by subregion” to get the list of “ Country, Cites, subregions” you search term is most popular in and take advantage of that.
You can explore lots of examples for these here I am taking “flooring.”
When I am searching for flooring, I can see Montana has 100%. So, I measured a place where there is the need for my products and services. Now, I have to focus on SEO aspects to reach people and sell my product or services.
Most of the people these days target youtube, and I think I don’t have to say that because almost all of you know about the popularity of youtube.
If you want to get more views on your videos?
Then redefine your video strategy by analyzing what people are searching on youtube with the help of google trends.
You can do a specific search for youtube queries by hitting scroll down option on web search and select youtube search.
Here I searched for “Fortran,”I can see both upward and downward graphs, but presently it has no searches. So, as a YouTuber, you have to smart and skip this result.
Now, this is it.
These are the best and practical techniques which you can use to find the best and untapped keywords.
Now, I want to turn it over to you:

From past few months, there is a lot of buzz hovering over the social media’s about the Android 9 Pie and the latest features of Android 9 pie. But no one knows when exactly the next big version of Android OS will be rolling out.
Now, it’s official, Google has just released their final version of its Android P. Although this version is previewed at the Google’s annual developer conference which is conducted back in the may it has released in August.
This new version is available on all the google pixel phones. And you can get this update soon on the other devices which have signed the companies beta programme.
Now, you might be wondering about “what are the biggest features of android 9 pie”?
If you want to know about them means don’t worry, here in this post I’ll cover all the biggest features of Android 9 pie.
In this post, I have covered the ten biggest features of Android pie which have caught our attention. So, let’s get into the most significant features of Android 9 Pie.
Google’s new android pie update has rolled out with the fantastic navigational gestures. They just took a piece out of the iPhone X’s and refined that piece and added to their new version of Android P. In Android P you can see refined navigational gestures which are created based on the users intent which they found out in Android P beta testing earlier this year.
The brand new home button is changed into the slim dash which looks fantastic on the device. Here to browse all you have to do is slide up from the thin dash that’s it. When you long press the digital button means google assistant will pop up to help you.
You can also see your most recent apps appear with the full-screen previews which you can flick through. Usually, you will have lots of space on the home screen, and it makes your phone look longer and easier to access. You can even access this phone quickly with a single hand.
As said, google new android p has interactive recent apps features. This new interactive app feature gives you more control over your recent apps. All you have to do is horizontally swipe your screen to get the full-screen previews of your recent apps. This new version has the multitasking booster which helps to do multiple tasks at a time.
This mode supports quick text selection, which means you can quickly copy the text from one app to the other app.
Google has included a new “digital wellbeing dashboard” on its latest version of Android Pie. It gives you the unobstructed view of how you used your android phone. You can see every statistics and time spend on your apps.
This dashboard will help you to realize how much time you are spending on your phone and you can even cut down your phone usage to some extent by using this app. You can also check how many times you unlocked your device and home many notifications you received throughout the day and so on.
So, this is a helpful feature to manage your time as a well to organize your time. Presently it is working on pixel devices only it will roll out to the other devices this fall.
App timer is another excellent tool which helps you to cut down your time on apps. You can tap into the apps you are, and you can set the time limit for those apps in your daily usage.
Usually, people love playing games, and some people enjoy watching youtube? If you are the one who wants to cut down your playing time and videos time, then you can use this efficient app timer which can notify and stop the app.
You can set your own time such as 15 mins, half an hour, one hour, or three hours, etc. the choice is yours once you set the timer. It will work until that time after the time limit reachable the app will fade out from your home screen, and you can relaunch the app.
This is one of the useful features to control kids from playing excessive games on mobile. That’s why I mentioned this point in the biggest highlights of Android 9 Pie.
Usually, when I say this a new update, you’ll say “do not disturb” is an old feature. Right?
Yes, do not disturb is on the most phones but there is a difference between that feature and this feature. In old “do not disturb” feature it prevents you from hearing notifications. Although this is a useful option in meetings and conferences but it isn’t ideal when you are at your home or your bedtime.
The new upgraded version of do not disturb takes out all the visual indicators so that you can’t get alerts such as messages, snaps, emails and so on. Google is also adding a new feature which can turn your phone on its face to merely activating “do not disturb” mode automatically so there will be no interruptions.
Google has brought more changes to the past version of Android just by analyzing past experiences. It has taken machine learning experiences to get proactive suggestions quickly. This new tool predicts the next step you want to do with the app and do take that action.
The actions are purely based on the Android pie program which previously learned about your particular pattern like how you answered your calls and so on.
The new adaptive battery feature is one of the best features you have to talk about the Android Pie. Usually, not all apps require equal time and don’t have to use your battery life. Android pie exactly does that it will not allow all apps to eat your battery life. It will smartly monitor your battery, and it saves your battery life.
This new version of the Android pie has a unique feature which decides whether to give power to the apps or not. So, this feature can reduce CPU app wake-ups by 30% and this can help you to improve your phones battery life.
If you are struggling with app notifications? Then don’t worry the Google’s Android pie will take care of those notifications. If there is an app which continuously shows notifications means Android pie will dismiss those notifications. This app is smart enough to notice which is the perfect notification for you.
After a while, you will be asked to choose the notifications options. Long press on notifications means it will directly take to the notifications settings and you can do your desired changes there.
The slices in the Android pie is another useful feature. Usually, slices will quickly let you access all the shortcuts in the google search. If you are searching for any ride, then you can quickly click on uber slices to open and book instantly.
With this android p, you can quickly give Gmail like intelligent replies to your incoming messages. These are nothing but the automated responses which shows up as a reply to your mail or your chat. It is generated by using a machine learning algorithm. These special message has come to the new android pie to save your time and effort of typing.
These are the special and biggest features of the Android 9 Pie.
Now I want to turn it over to you:
Which of these features do you like most?
Which of the features you love are missing in this post?

It is possible to extend the fibre optical data transmission links by optical amplifiers. This was shown by the Estonian and Swedish researchers by using the new phase-sensitive amplifiers (PSAs). The extent of reach is almost six times that which is possible when the conventional optical amplifiers are used.
The extent of reach and capacity of the current fibre optical data transmission links have certain limitations. This is mainly due to the noise accumulation that originates from the optical amplifiers in the link and signal distortion that occurs from nonlinear effects in the transmission fibre. Both these problems can be considerably reduced when phase sensitive amplifiers (PSAs) are used.
The researchers from Chalmers University of Technology, Sweden and Tallinn University of Technology, Estonia, have shown that there is a six time increase in the extent of reach as compared with the conventional optical amplifiers. They have shown a 4000 km fibre-optical transmission link using ultra low noise, phase sensitive optical amplifiers. Their findings have been published in Nature Communications.
The researchers used a multi-channel compatible and modulation-format independent transmission link with in-line PSAs. They showed that there is a reach improvement of 5.6 times at optimal launch power using the phase sensitive optical amplifiers operating at an accumulated non-linear phase shift of 6.2 rad. There were two data-carrying waves that were transmitted and they occupied twice the bandwidth. Twice the total power was propagated as compared to the phase-insensitively amplified link.
These results that were obtained showed that when the in-line phase sensitive optical amplifiers which offer low-noise amplification and non-linear mitigation are used, they could provide nonlinear tolerance and also a greater transmission reach.
Professor Peter Andrekson who is heading the research on optical communication at Chalmers University of Technology says that there are great advantages and benefits in using these phase sensitive optical amplifier in optical communication. There are a few engineering challenges that need to be overcome before these results can be used commercially.
In today’s day and age there is a great demand for higher transmission capacity. This is seen in video streaming, cloud storage and other online services which require high transmission capacity. In order to meet this demand, new technologies need to be explored. The technologies are being explored the world over to find solutions that will have significant improvements over those that are currently in existence. The phase sensitive optical amplifiers can provide a great amount of reach improvement over the conventional optical amplifiers. This will enhance the performance of future fibre optical communication systems. These optical amplifiers can be used to serve the purpose of the increasing demands of higher transmission capacity.
These phase sensitive optical amplifiers can also be used in quantum informatics and related areas, wherein the generation and processing of quantum states are involved. The ultra-low noise amplifiers can play a vital role in spectroscopy or other applications.
This research has received funding from the European Research Council (ERC), the Swedish Research Council and the Wallenberg Foundation.
For a long time scientists have struggled with something humans find extremely easy and even take for granted- the ability to grasp things. In the field of robotics getting to robotic grasping has been a very difficult task and has been achieved to only a limited degree. At present robotic grasping takes place in a controlled environment with things all being in one place. But what happens in an unorganized setting with things continuously being changed in position?
Scientists at QUT have come up with a way by which robotic Grasping can take place in a changing environment and this method involves fast and accurate action. With this basic ability being mastered by robots, a number of opportunities in both the domestic and industrial front will open up for robotics, especially if it has to do with robotic grasping.
In the real world things continuously keep changing and robots need to continually adapt to not only their surroundings but also where things are in their surroundings before being able to grasp them.
One of the methods developed by scientists is a real time object independent grasp synthesis method.
This method uses Generative Grasping Convolutional Neural Network to predict the quality and pose of a two pronged grasp. All the robot has to do is map what’s in front of it and then grasp it. There is no need of a trial and error approach, thus saving a lot of time.
In real world situations scientists achieved an 83% robotic grasping rate with unknown objects that was not previously programmed with the robot and an 88% robotic grasping success rate when it came to household objects and an 81% success rate when it came to picking up things in an environment with dynamic clutter.
With the new method scientists discovered, robots can process images of the item they want to pick up in about 20 milliseconds and decide on the best approach to picking it up.
Scientists believe that their approach to robotic grasping would not only enable robots to be used in a factory setting where everything can be found in one place and is structured but also in an unorganized setting or ones with a lot of clutter or places where the robot is required to adapt to changing environments.
Taking a cue from the new method of robotic grasping invented by scientists from QUT, robots can be used in a number of settings including in warehousing to lift and put objects in place or vice versa, in online shopping when it comes to sorting and picking things out according to a person’s order or even in groceries when it comes to picking and putting stuff in trollies.
In a domestic setting, robots could be used to not only vacuum and mop floors but also in picking up things and putting them away in their proper places.
Technology has changed the travel and tourism industry a lot, whether we like it or not it has simply changed the way our world works. People are more convenient with their journeys now rather than in the old days.
Traveling has been increased tremendously with the help of technology. In a recent study, according to the world tourism organization, it is believed that by 2030, two billion international trips will take place by approximately 8.5 billion people.
That’s a huge number and that’s the main reason why the travel and tourism industry constantly transforming themselves in numerous ways by taking the help of technology to sustain. Technology is simply changing the ways we travel and it helped us to travel faster. It also helped us to have the better quality journey and more comfortable accommodations together with the help of the hospitality industry.
Technology has transformed the consumption behaviors of the travelers and as a result travel and tourism industry has advanced tremendously.

In this modern age, people are exploring a lot of content through their phone. So the travel and tourism industry has focused mainly on the travel application development to improve the traveler’s experience.
With the help of new technologies, they are created well-crafted travel applications which are highly useful for their users. Generally, you will get any information regarding your trip on these travel applications. You can even book your trip or you can cancel your trips from these user-friendly mobile apps. As the technology has changed the landscape of tourism and travel industry, companies are investing more and more in their travel application development to help travelers.
As a traveler, you can get a lot of benefit from these travel applications. So, this is the other significant factor of technology. A recent study proves that 85% of users make use of the travel applications and planning their holiday trips. So, from that, you can think about how this has changed the outcome of the travel industry.
When I say social media driven marketing there is no denying. Social media has had a dramatic impact on the travel industry and it changed the way we experience the world around us.
Although there are other industries which are significant in marketing opportunity tourism marketing is the best match for the digital heaven.
It is because the travel is one of the most shared topics on the social media. The three giant networks Facebook, Twitter and Instagram has lots of traveling topics which are shared vigorously on the internet.
People generally love sharing new and unique experiences of travel on their social media pages. Which is playing a proper impact on the travel marketing. They also love to tell the traveling networks about their upcoming travel plans and other trip plans way before. This is information is, in fact, the gold mine for travel marketers.
This is how the technology and social media has been driving travel marketing a lot and at the same time, it is helping travelers to get a good trip offers a unique experience on their trip.
The technology significantly helped the travel industry to create a major impact on the internet. It has a massive impact on tourism both for the consumers and for providers. Most of the studies proved that the travel industry is having a huge impact on the internet.
The development and contribution of the air travel as a means of transporting the tourists to the different locations is an important contribution of technology which has made the people talk more.
Along with that, the significant development of low-cost carriers is the other means of successful application in the tourism which has impacted the audiences. As the people used to search or talk about the travel industry it has created the major impact on the internet.
Usually, people used to dial customer cares numbers and due to the heavy number of caller’s people always get busy or kept on hold tones. Now, with the help of the digital technology the travel world has changed a lot. People found new ways to connect and so as the travel agencies.
Digital technology has completely changed the way people used to connect with airlines and other travel, it has created a 24/7 relationship with the people who want to resolve their issues.
These are the few factors how technology is changing the travel and tourism industry.
Technology has transformed each and every phase of the travel and hospitality industry from finding a hotel, to check in process and also to unlock the door and other personalizing activities. It will do even more in the future, so let’s watch out for the next few years how the new technology innovations will help travelers.
So, what are your thoughts about the technology in the travel and tourism industry? Let us know them in the comments section. We’d love to check out your views on the shaping of technology.
If you are reading this article, it is a fair bet that you are interested in selling your old gadgets that is either out of date or no longer in use. Giving it away isn’t going to be like donating to charity because you have had sentiment to it in the past as well as now. You don’t have to find out how to dispose it off safely either because there are better options – one that will fetch you a reasonable, and in some cases, unbelievable amount of cash.
Today, there are several ways to sell your unwanted gadgets. There are plenty of websites and retail stores that buy back your outdated electronic items that are collecting dust in a corner. Then there are individuals who are gadget collectors looking for deals. Unfortunately, not all of these stores or personnel see your once treasured possessions as valuable. So, a little knowledge about your gadget, knowing how much it is actually worth in the current market can come very handy in such situations. In cases where you think your gadget can guarantee your future financial freedom, the cost of using an appraiser, in all likelihood, is worth the effort.
Not every gadget is suitable to be resold. Before you begin your quest to find out the real value of one, you need to determine whether it is worth the postage or gas money. Comparemymobile.com is a website that helps you find out exactly that – the amount that various companies are willing to pay for your electronics. Here, you will also obtain more information related to that particular electronic, recent trends and much else. The fact that the rules for setting a price for a specific device aren’t rigid, you will find a lot of difference in resale value from one company to another.
