Oppo is said to be prepping to launch two new TWS earphones in India. As of now, the company offers a wide range of wearables in the audio segment. The Enco M31 is one of the best neckbands around in the price range. Further, you have offerings like the Enco Free, Enco W51, and Enco W31. The Enco X is the most premium TWS earphones from Oppo and they are priced at ₹9,999. Now, the company is all set to launch two new earbuds in India. You could soon get the Oppo Enco Buds and Enco Air in the market. According to a new report from 91Mobiles, Oppo is readying a new duo of TWS earphones to launch in the Indian market. Both TWS earbuds were launched globally earlier this year. However, the company is yet to confirm the India launch date. Looking at the prices in Thailand, we can safely say that the Oppo Enco Buds could be a budget offering. They may cost around ₹2,500. They feature an 8mm dynamic driver on each earbud. Connectivity includes Bluetooth 5.2 with up to a 10m operational range. As for the batter, the TWS earbuds each pack a 40 mAh cell. The charging case has a 400 mAh battery and can be charged completely within 2.5 hours via a USB Type-C port. Coming to the codecs, they support AAC and SBC audio formats. The earbuds come with intelligent noise cancellation as well. On the other hand, Oppo Enco Air have a stem design. They support 12mm dynamic crystal clear vocal drivers with a driver sensitivity of 112±1 dB at 1 kHz. They are tipped to offer up to 24 hours of battery life on a single charge with the case included. They can also offer up to 8 hours of juice within a 10-minute charge. Each earbud has a 25 mAh battery, whereas the charging case has a 440 mAh unit. Moreover, the earbuds come with two microphones that are used for AI-powered noise-cancelling during calls.

Regular expressions (regexes) are widely used in different fields of computer science. However, the Regular expression Denial of Service (ReDoS) vulnerability forms a class of common and serious algorithmic complexity attacks. The existing ReDoS-vulnerability detection tools have defects of low precision or low recall rate due to the lacking of formal and comprehensive detection conditions of ReDoS-vulnerabilities. A research team led by Prof. Chen Haiming from the Institute of Software of the Chinese Academy of Sciences developed high-performance detection tool for ReDoS-vulnerability. Their study was issued at USENIX Security Symposium 2021. Through examining massive ReDoS-vulnerable regexes, Chen's team proposed the ReDoS-vulnerability detection conditions, namely the ReDoS-vulnerability patterns, and gave the necessary conditions for triggering these patterns formally. Based on this, they developed a static and dynamic combined ReDoS-vulnerability detection algorithm, and designed ReDoSHunter, the ReDoS-vulnerability detection tool. ReDoSHunter can pinpoint multiple root causes in a vulnerable regex, prescribe the degree of the vulnerability and generate attack-triggering strings, etc. It has achieved 100% precision and recall ratio on datasets of Corpus, RegExLib and Snort with 37,651 regexes. In detecting the publicly-confirmed practical vulnerabilities in Common Vulnerabilities and Exposure (CVE), ReDoSHunter can detect 100% ReDoS-related CVEs. In their previous study, Chen's team proposed a programming-by-example framework, FlashRegex, for generating anti-ReDoS regexes by either synthesizing or repairing from given examples. It is the first framework that integrates regex synthesis and repair with the awareness of ReDoS-vulnerabilities. FlashRegex can efficiently generate or repair regexes without ReDoS-vulnerabilities, and there're 0 ReDoS-vulnerabilities in repaired regexes. The study, titled "FlashRegex: deducing anti-ReDoS regexes from examples," was issued at ASE 2020.

A mouse with a lightning quick hero sensor for less. Logitech's G502 Lightspeed mouse typically tends to get most of the attention when talking about Logitech's best gaming mouse contenders, but it's not the only lightspeed gaming mouse under the Logitech umbrella. If you're willing to supply your mouse with the occasional AA battery, there's also the Logitech G604, which has the same wireless tech as the G502, the same sensor, more buttons and is now at its lowest price since 2019 over at Amazon. Part of what makes the G502 so po[CENSORED]r is how it borrows its design and ergonomics from the wired Hero/Proteus Core mouse, which was Logitech's flagship gaming mouse before the wireless Lightspeed brand. But while that mouse was built specifically for shooters, its 11 programmable buttons can sometimes come up a little short for players who prefer genres like MMOs and MOBAs. Enter the Logitech G604 Lightspeed. It's got 15 programmable buttons, including 6 side buttons, plus the same lightspeed wireless tech and hero sensor as the G502. That means it can support DPIs up to 25,600 and has the same 1ms report rate when lightspeed tech is turned on (there's also a regular Bluetooth mode that drains battery more slowly). It does, however, lack the G502's removable weights, which let you adjust that mouse's heft. In exchange, though, you get a scroll wheel that can either move in set, ratcheted increments or scroll smoothly with the press of a button. The key tradeoff with this mouse is that it requires a AA battery rather than charging via an internal battery, so it may not be the best wireless mouse for you. But Logitech also advertises that you can get 240 hours of life off of one battery in lightspeed mode and 5.5 months in the less-demanding Bluetooth mode. If you're looking for a premium mouse but are willing to sacrifice weights and an internal battery for more buttons and a cheaper price, this is a great pick

Also: the game is coming to Steam this week after a period of Epic exclusivity. After a year of Epic Games Store exclusivity, Mortal Shell hits Steam on August 18. That’s a day before the release of The Virtuous Cycle, a big new expansion for Mortal Shell which adds a roguelike mode, a new playable shell (the game’s take on classes) and a new transforming weapon reminiscent of Bloodborne’s trick weapons. The expansion sounds promising, and if you own the game there’s no reason not to check it out: It’ll be free to keep from August 18-22. That means if you buy Mortal Shell, you’ll be able to ‘get’ the DLC pack on Steam free of charge. The offer applies to all available platforms, which presumably includes the Epic Games Store for players who already own it there. The roguelike mode features all the trappings you’d expect: the world is randomized, there are upgrade pillars dotted throughout the map, and there are “more than 100 upgrades” ranging exotic weapons through to “entirely new maneuvers.” The new shell is Hadern, which comes bearing talents including dagger mastery. Mortal Shell is among the better Soulslikes, scoring an 80 in our review. “Enjoyably tough and esoteric, if a little uneven, Mortal Shell is a decent debut from Cold Symmetry,” Rick Lane wrote.

Researchers were able to 'switch off' the genes behind the insect's famously long legs. Scientists have created "daddy shortlegs," a stunted version of the common household pest daddy longlegs, by suppressing the genes behind the arachnid's famously elongated limbs. Daddy longlegs, also known as harvestmen or crane flies, belong to the class Arachnids — a group of eight-legged invertebrates that includes spiders, scorpions, ticks, mites and horseshoe crabs. There are more than 6,500 species of daddy longlegs in the order Opiliones, each of which is characterized by flexible legs that are several times longer than the individual's body. In a series of new experiments, a team of researchers mapped the entire genome of Phalangium opilio, the most common species of daddy longlegs, and isolated the genes responsible for their famous long legs. The researchers then turned off the long leg genes in developing embryos, creating individual arachnids with shorter, deformed legs. Our purpose was not just to shorten their legs just for the sake of it," lead author Guilherme Gainett, a graduate student at the University of Wisconsin-Madison, told Live Science. "We wanted to understand more about how these fascinating creatures evolved their alien way of locomotion and body plan." Unlike true spiders, daddy longlegs don't use all eight of their legs for walking; instead, they use three pairs for locomotion and the remaining, and longest, pair, they wave around to feel their way around, Gainett added. Mapping the genome The researchers took two years to map all 580 million base pairs of the P. opilio genome, which is around one-sixth the size of the human genome, Gainett said. Once that was done, researchers searched the DNA map for genes likely to cause long legs, by comparing the P. opilio genome with the genomes of other insects, such as the fruit fly (Drosophila melanogaster), in which scientists had already figured out which genes code for legs, Gainett said. The comparison revealed two Hox genes — a group of related genes that code for specific body parts during embryonic development — known as Deformed (Dfd) and Sex combs reduced (Scr), that were tied to leg development in other species. Switching off the genes The researchers were confident that the Dfd and Scr genes played a role in the development of long legs in P. opilio. But it was not clear if both needed to be turned off, or if some combination was sufficient, to change leg shape and size, Gainett said. Therefore, the researchers down-regulated these genes in developing embryos to see if the change would interfere with the development of their long legs. To do this they used a process known as RNA interference, which is inspired by a process living cells use to ward off viruses. When viruses invade cells, a protein structure known as the RISC complex identifies the invaders' double-stranded RNA. The cell can then target and turn off the corresponding messenger RNA (mRNA), single-stranded RNA used to help transcribe or read genes, which viruses use to reproduce within the cell, Gainett said. However, organisms also produce mRNA to create new proteins. So the scientists repurposed the RISC complex to silence the mRNA of the Dfd and Scr by disguising those genes as viruses. "By synthesizing artificial double-stranded RNA matching your gene of interest and injecting it into the embryo, it is possible to interfere with the expression of that gene," Gainett said. Deformed legs Switching off both the Dfd and Scr genes resulted in individuals with three pairs of shortened "walking" legs. They also changed shape. "When the Hox genes are down-regulated these leg appendages transform into short food-mani[CENSORED]ting appendages called pedipalps," Gainett said. In addition to being much shorter than their normal legs, pedipalps have six segments, instead of the usual seven in regular legs; pedipalps also lack special joints known as tarsomeres, which give their legs the flexibility needed to properly move around and help sense the world around them, Gainett said. However, not all the embryos' legs became shorter. The fourth pair of legs still grew to their usual length. "This is because the fourth pair of legs likely requires the input of a third Hox gene to set up their fate," Gainett said. "This is something that we are currently investigating," he added. Some of the deformed embryos hatched with their shortened legs, but they all died before reaching adulthood, Gainett said. Understanding arachnids The findings help shine light on one of the most unusual body plans in the animal kingdom, Gainett said. "They [daddy longlegs] have been around for far longer than we have, around 400 million years, and to me, it is just amazing that we can make inferences about how animal morphologies evolved long ago and understand a bit more about the creatures we share our planet with," he added. Gainett hopes that the findings could also lead to breakthroughs in understanding other arachnid body parts. think future studies have the potential to clarify how other unique structures of arachnids are formed, such as the chelicera [fangs in spiders]," Gainett said.
