Unveiled at a Berlin launch event under the theme “Fashion Next,” the new lineup balances high-precision health tracking, expressive industrial design, and a more universal approach to platform compatibility. The headline announcement is the Huawei WATCH 5, now joined by a re-engineered FIT 4 Series, all built to run on both Android and iOS devices. Designer: Huawei TruSense and the Rise of Fingertip Biometrics Central to the WATCH 5 is the introduction of Huawei’s TruSense System, anchored by the Multi-sensing X-TAP module. Rather than relying on wrist-bound photoplethysmography alone, X-TAP brings health interaction directly to the fingertip. It provides faster and more granular readings through a gesture-based input system. The device supports quick-tap gestures like Double Tap and Double Slide. This reduces the need for menu-diving or screen tapping during workouts or daily routines. These are not just shortcuts. They are structured interactions that keep the wearable experience fluid without compromising data access. The hardware reflects a deliberate balance of elegance and performance. Sapphire glass curves over aerospace-grade titanium and 904L stainless steel, a pairing typically reserved for luxury watches. For the first time, the WATCH 5 ships in two sizes, 46mm and 42mm. This brings comfort to a broader user base without diluting the design language. Rebuilding the FIT Platform The FIT 4 Pro stands as a complete rework of Huawei’s entry-performance tier. At just 9.3mm thin, it trades visual weight for technical density. New water-resistance support extends tracking to diving depths of up to 40 meters. A reworked air pressure sensor now delivers elevation data tuned for trail running and mountain climbs. Offline map support and sport-specific modes such as golf, diving, and trail training turn this into a multi-condition training device. Build materials signal a shift in direction. Aviation-grade aluminum and titanium alloy bezels bring FIT 4 Pro closer to the sophistication of the WATCH 5. Sapphire glass has also been added for enhanced durability, especially in high-contact outdoor use. Interoperability and Expanded Harmony Both the WATCH 5 and FIT 4 Series operate independently of a Huawei smartphone. iOS and Android support remains intact. Gesture controls and activity syncing are supported across Huawei’s broader ecosystem. The launch also included FreeBuds 6, which work seamlessly with the wearables. Open-fit audio now enters a higher fidelity tier thanks to new dual drivers and refined voice call algorithms. The MatePad Pro 12.2 was also introduced. Its value lies in its role as an accessory-level companion, especially with the tandem OLED PaperMatte display and Huawei Glide keyboard. Battery longevity has been improved across the entire range. Huawei is targeting users who expect multiple days of uptime without sacrificing display brightness or connectivity. These are not devices designed to stay tethered to a charger. Pricing and Availability Pre-orders are now open. The Huawei WATCH 5 starts at £399.99. The FIT 4 and FIT 4 Pro are priced at £149.99 and £249.99 respectively. FreeBuds 6 will be available at £139.99. All product lines will be available from the Huawei Store, with retail launch scheduled for May 26. Huawei’s wearables are no longer treated as a secondary category. With TruSense and X-TAP, the brand is defining a new path in user-driven health technology. Everything is wrapped in high-finish industrial craft. This is not a spec war. It is a recalibration of what daily smartwear should feel like when hardware and wellness are developed as part of the same conversation.The post Huawei Redefines Its Wearable Future with WATCH 5 and FIT 4 Series first appeared on Yanko Design.

Posted on : May 15, 2025 By Tech World Times Education  Rate this post Research should be fair, honest, and accurate. But sometimes, bias enters and ruins the results. One common bias is selection bias. It happens when certain people or data are left out. Let’s explore the meaning, causes, examples, and solutions of selection bias in simple words. Define Selection Bias Let’s first simply define selection bias. Selection bias happens when a sample does not represent the full population. It affects research accuracy and leads to wrong or unfair conclusions. If the data selected is not random or fair, bias can occur. To define selection bias clearly: It is a type of error that happens when certain groups are more likely to be included or excluded. As a result, the study does not reflect the full picture. Causes of Selection Bias Let’s look at common causes of selection bias. These are often simple mistakes but with big effects. 1. Non-Random Sampling This happens when participants are chosen on purpose. For example, a survey is only for people in one city. It leaves out others and does not reflect the entire population. 2. Self-Selection Sometimes people decide whether to join a study. This means only people with strong opinions may take part. It creates an unfair sample and leads to bias. 3. Loss to Follow-Up In long studies, some participants stop responding. If many drop out, the remaining group may no longer represent the original group. 4. Exclusion Criteria Researchers sometimes exclude certain data or people. This may be needed, but it can cause bias if not handled carefully. 5. Sampling from a Special Group If you only pick people from a school, hospital, or gym, it may not represent the general population. Examples of Selection Bias Let’s make the meaning more clear with real-life examples. Example 1: Health Study A study on exercise includes only gym-goers. This group is likely healthier than others. So, the results do not apply to everyone. Example 2: Online Poll A poll about internet use is shared only on Twitter. Older people or non-users are left out. This leads to biased answers. Example 3: School Survey A survey about education includes only top-performing schools. It ignores schools with fewer resources. This makes the results unfair. Example 4: Medical Research A drug test only includes young adults. It skips older or sicker patients. The drug may not work the same for everyone. Why Selection Bias Matters Selection bias leads to wrong findings. It can harm real-life decisions, like health, law, or policies. Biased studies may waste time, money, and even risk lives. That’s why it’s important to fix it early. Solutions to Avoid Selection Bias Now that we have defined selection bias and seen its causes, let’s solve it. 1. Use Random Sampling Random sampling means everyone has an equal chance to be selected. It makes the sample more fair and balanced. 2. Ensure Large Sample Size A bigger sample reduces the effect of bias. Try to include as many different people as possible. 3. Keep Participants Engaged In long-term studies, follow up regularly. Use emails, calls, or visits to reduce dropouts. 4. Pre-Test Your Method Before the main study, test your sample plan. See if some groups are missing or over-represented. 5. Be Transparent Always explain how your sample was chosen. Mention any limitations in your study report. 6. Use Weighting Methods If some groups are over- or under-represented, adjust the weight of their data. This helps balance the results. Conclusion To get accurate results, we must avoid bias. Selection bias is a major cause of poor research. It happens when the sample does not represent the whole group. We have discussed what it is, how it happens, and how to fix it. To define selection bias simply: It is when your study misses some parts of the population. This leads to false, unfair, or misleading results. Always choose samples wisely. Avoid shortcuts. Use fair methods and stay honest in your research. This will help you get real, helpful, and trustworthy results. FAQs 1. What does “define selection bias” mean? It means to explain what selection bias is. Selection bias is when the chosen sample is unfair or unbalanced. 2. What is a real-world example of selection bias? A survey shared only online may miss people without the internet. This makes the sample biased. 3. Can selection bias be removed completely? It can be reduced but not always removed fully. Using random sampling and large groups helps a lot. 4. How does selection bias affect research? It makes the results unreliable. You may draw wrong conclusions from the study. 5. Is self-selection a form of selection bias? Yes, when people choose to join a study, it may lead to bias. 6. Why is it important to define selection bias in reports? It helps readers understand the study’s quality and limits. It also shows honesty from the researcher.

Hackers have been stealing Coinbase customer information by bribing the company’s overseas support agents for access. The scheme affects a "small subset of customers," the popular cryptocurrency platform said on Thursday. "Their aim was to gather a customer list they could contact while pretending to be Coinbase—tricking people into handing over their crypto,” the company wrote in a blog post. Fortunately, the hackers had no access to user passwords, two-factor authentication codes, or the private keys for any cryptocurrency accounts. Still, in some cases, the cybercriminals successfully phished affected customers using stolen data, which included names, addresses, phones, email addresses, the last four digits of Social Security numbers, “masked bank account numbers,” government ID images such as driver’s license, along with balance snapshots and transaction histories. Unsuspecting victims then sent their cryptocurrency to the scammers, believing them to be official Coinbase representatives. In addition, the hackers even tried to extort Coinbase itself, demanding a $20 million payment from the cryptocurrency company to cover up the incident. However, Coinbase refused to pay and instead disclosed the hacking activity to warn users.    The scheme risks endangering customers who regularly use Coinbase for cryptocurrency transactions. “Less than 1% of our monthly transacting users had their records accessed,” CEO Brian Armstrong said in a video, without mentioning a firm number. Recommended by Our EditorsIn some good news, Coinbase plans on reimbursing users who fell for the phishing attempts. The company is also bolstering its security around customer support to prevent a repeat. “We’re actually relocating some of our customer support operations as a result of this,” Armstrong added. Coinbase is also offering a $20 million reward for any information that leads to the arrest of the culprits. “For these would-be extortionists, or anyone seeking to harm Coinbase customers, know that we will prosecute you and bring you to justice,” Armstrong said.Still, the hackers could use the stolen data to commit identity theft and other malicious schemes against the impacted users. Hence, victims should take measures to protect themselves. Coinbase says it already sent alert notices to affected customers, though details on the reimbursement process are scant. For now, the blog post merely says: “Coinbase will voluntarily reimburse retail customers who mistakenly sent funds to the scammer as a direct result of this incident prior to the date of this post, following a review to confirm the facts.”In the meantime, the company says it's working with law enforcement to ID the scammers.

Author Colour prediction games have gained massive popularity across digital platforms in recent years, especially in regions like India. These games are easy to play, visually engaging, and promise quick results. But there's one question that every player or potential participant asks: Are colour prediction games based on luck or skill? This article dives deep into the mechanics, psychology, and patterns of these games to answer that question thoroughly. Understanding Colour Prediction GamesColour prediction games are a category of online games where players predict the outcome of the next color (often red, green, or violet) that will appear on a screen or wheel. If their prediction matches the result, they win and earn rewards. Many platforms and apps host such games, often labeling them as entertainment or lottery-style games.One such platform making waves is the 82 lottery game, which combines colour prediction with a digital lottery model. This has led to increased searches for 82 lottery download, as users are eager to try their luck or test their predictive skills on these platforms. The Appeal of Colour Prediction Games in IndiaIndia has witnessed a surge in casual gaming, and colour prediction games India has become a trending search term. With the rise of smartphone penetration and cheap internet access, millions are participating in these games, either for fun or for potential monetary gain.Games like lottery 82 not only offer a chance to win but also present an exciting challenge. The minimal entry barrier, instant results, and the possibility of winning make these games a top choice among young players and casual gamers. Are They Games of Luck or Skill?This is the core question — are these games purely chance-based, or do they require a level of skill? The answer isn’t entirely black and white. The Argument for LuckMany players argue that colour prediction games are fundamentally based on luck. Since the outcomes are typically generated by Random Number Generators (RNGs), each result is independent of the previous ones. This makes it almost impossible to accurately predict the next outcome using any pattern or strategy.Moreover, games like 82 lottery game or others on any colour prediction website often operate similarly to online lotteries, where luck plays the dominant role. In such cases, previous results offer little or no clue about the future outcome. The Argument for SkillOn the other hand, some seasoned players believe that there is a skill element involved, especially in understanding patterns, probability, and psychological tactics. These players use data analysis, game theory, and risk management strategies to make predictions that are slightly better than random guessing.Moreover, experienced users who frequently engage with platforms like lottery 82 often claim that consistent gameplay, proper bankroll management, and emotional control contribute significantly to success. Elements of Skill That May Influence ResultsWhile RNG systems are designed to be random, some subtle aspects of gameplay and human behavior can introduce a skill factor:Pattern Recognition: Some platforms may not use perfectly random systems, and users sometimes identify patterns.Probability and Statistics: Understanding odds and probability distribution helps make informed decisions.Risk Management: Smart players avoid all-in bets and stick to calculated risks.Experience: Like poker or fantasy sports, experience might provide an edge over new players.So while luck dominates, there is some room for skill—particularly on platforms where data transparency or algorithmic design allows for analytical prediction. Responsible Gaming Is KeyWhether you're playing the top colour prediction game or downloading the latest 82 lottery download, it’s crucial to play responsibly. These games can be entertaining and even rewarding, but they should not be seen as a reliable income source. Set a budget, know your limits, and avoid chasing losses.Several colour prediction websites now also offer responsible gaming features to help players manage their time and money effectively. This is a positive step, especially in markets like India, where regulatory frameworks are still evolving. Final Verdict: Luck or Skill?In conclusion, while colour prediction games may seem like they involve skill due to the decision-making element, the majority of their outcomes are driven by randomness. Luck plays a significant role, especially when RNG systems are involved. However, with proper strategies and experience, a small skill factor might influence outcomes in a player’s favor.For casual players, games like lottery 82 or the top colour prediction game provide thrilling entertainment. But always remember — treat them as games, not as a source of guaranteed earnings. Keywords Summary:82 lottery game: A popular colour prediction platform.82 lottery download: Refers to downloading the mobile version of the 82 lottery game.lottery 82: Another name or variant of the 82 lottery platform.top colour prediction game: Highlights the most popular platforms in this genre.colour prediction games India: Discusses the rise of such games specifically in the Indian market.colour prediction website: Refers to platforms offering these games online. Final ThoughtsThe rise of colour prediction games reflects our age-old fascination with prediction, chance, and challenge. Whether you're in it for fun or the thrill of winning, always remember the balance between luck and skill. Play smart, stay safe, and enjoy the colourful world of online predictions.

Alibaba has unveiled Wan2.1-VACE, an open-source AI model designed to shake up how we create and edit videos.VACE isn’t appearing out of thin air; it’s part of Alibaba’s broader Wan2.1 family of video AI models. And they’re making a rather bold claim for it, stating it’s the “first open-source model in the industry to provide a unified solution for various video generation and editing tasks.”If Alibaba can succeed in shifting users away from having to juggle multiple, separate tools towards one streamlined hub—it could be a true game-changer.So, what can this thing actually do? Well, for starters, it can whip up videos using all sorts of prompts, including text commands, still pictures, and even snippets of other video clips.But it’s not just about making videos from scratch. The editing toolkit supports referencing images or specific frames to guide the AI, advanced video “repainting” (more on that in a sec), tweaking just selected bits of your existing video, and even stretching out the video. Alibaba reckons these features “enable the flexible combination of various tasks to enhance creativity.”Imagine you want to create a video with specific characters interacting, maybe based on some photos you have. VACE claims to be able to do that. Got a still image you wish was dynamic? Alibaba’s open-source AI model can add natural-looking movement to bring it to life. For those who love to fine-tune, there are those advanced “video repainting” functions I mentioned earlier. This includes things like transferring poses from one subject to another, having precise control over motion, adjusting depth perception, and even changing the colours.One feature that caught my eye is its ability to “supports adding, modification or deletion to selective specific areas of a video without affecting the surroundings.” That’s a massive plus for detailed edits – no more accidentally messing up the background when you’re just trying to tweak one small element. Plus, it can make your video canvas bigger and even fill in the new space with relevant content to make everything look richer and more expansive.You could take a flat photograph, turn it into a video, and tell the objects in it exactly how to move by drawing out a path. Need to swap out a character or an object with something else you provide as a reference? No problem. Animate those referenced characters? Done. Control their pose precisely? You got it.Alibaba even gives the example of its open-source AI model taking a tall, skinny vertical image and cleverly expanding it sideways into a widescreen video, automagically adding new bits and pieces by referencing other images or prompts. That’s pretty neat.Of course, VACE isn’t just magic. There’s some clever tech involved, designed to handle the often-messy reality of video editing. A key piece is something Alibaba calls the Video Condition Unit (VCU), which “supports unified processing of multimodal inputs such as text, images, video, and masks.”Then there’s what they term a “Context Adapter structure.” This clever bit of engineering “injects various task concepts using formalised representations of temporal and spatial dimensions.” Essentially, think of it as giving the AI a really good understanding of time and space within the video.With all this clever tech, Alibaba reckons VACE will be a hit in quite a few areas. Think quick social media clips, eye-catching ads and marketing content, heavy-duty post-production special effects for film and TV, and even for generating custom educational and training videos.Building AI models this powerful usually costs a fortune and needs massive computing power and tons of data. So, Alibaba making Wan2.1-VACE open source? That’s a big deal.“Open access helps lower the barrier for more businesses to leverage AI, enabling them to create high-quality visual content tailored to their needs, quickly and cost-effectively,” Alibaba explains.Basically, Alibaba is hoping to let more folks – especially smaller businesses and individual creators – get their hands on top-tier AI without breaking the bank. This democratisation of powerful tools is always a welcome sight.And they’re not just dropping one version. There’s a hefty 14-billion parameter model for those with serious horsepower, and a more nimble 1.3-billion parameter one for lighter setups. You can grab them for free right now on Hugging Face and GitHub, or via Alibaba Cloud’s own open-source community, ModelScope.(Image source: www.alibabagroup.com)Want to learn more about AI and big data from industry leaders?

There’s now data to back up the theory that stressful events like the loss of a loved one can change your heart’s physiology and contribute to atrial fibrillation, heart attacks, and stroke, among others. Researchers followed nearly 200,000 U.S. adults over five years and report that such instances were “high and unchanged” from 2016 to 2020, according to a research article in the Journal of the American Heart Association.Read More: Why Are We Addicted to Love?Stress Can Change Your Heart's ShapeThe term “broken heart syndrome” was coined in 1990, when a Japanese researcher noticed that stress can cause parts of the heart to temporarily enlarge and affect the ability of the organ to pump blood. Scientists suspect that the temporary ballooning is a reaction to a surge of stress hormones caused by a difficult emotional event. Although change tends to be short-term, it can still be fatal. It can be misdiagnosed as a heart attack, because even though the physical changes to the heart are different, the symptoms a patient experiences are similar.Over the course of the study — one of the largest ever of its kind — the death rate from the syndrome held steady, at 6.5 percent. Although more women than men experienced the syndrome, it was twice as fatal in men, with 11.2 percent of cases proving fatal, compared to 5.5 percent in women.Who Gets Broken Heart Syndrome“The continued high death rate is alarming, suggesting that more research be done for better treatment and finding new therapeutic approaches to this condition,” M. Reza Movahed, a cardiologist at the University of Arizona’s Sarver Heart Center in Tucson and an author of the study, said in a press release.Besides gender, age also appears to play a significant role in determining who gets affected by the syndrome. People older than 61 had the highest incident rates, but the data showed a substantial jump between the next two groups. Adults 46 to 60 were 2.6 to 3.25 times more likely to experience it compared to those who were 31 to 45 during the study.The data showed a slight variation of incidence by race. Socioeconomic factors like household income and insurance status may also play a significant role.Identifying Symptoms of the SyndromeThe study could raise awareness of the syndrome among both doctors and patients. For doctors, knowing that the symptoms resemble that of a heart attack can aide in diagnosis. If tests show that there are no physiological signs of a heart attack underway, they could still ensure the patient gets treated. Also knowing that the syndrome impacts many people under 60 could help diagnosis.For patients, recognizing that stress can cause these symptoms could help guide them to ways that could alleviate it. And recognizing that the symptoms are very much real, rather in their heads, could also prompt them to seek treatment.This article is not offering medical advice and should be used for informational purposes only.Read More: What Does the Heart Do?Article SourcesOur writers at Discovermagazine.com use peer-reviewed studies and high-quality sources for our articles, and our editors review for scientific accuracy and editorial standards.
