(Press-News.org) Deep learning techniques are drawing more and more attention to Web developers. A lot of Web apps perform inference of deep neural network (DNN) models within Web browsers to provide intelligent services for their users. Typically, GPU acceleration is required during DNN inference, especially on end devices. However, it has been revealed that GPU acceleration in Web browsers has an unacceptably long warm-up time, harming the quality of service (QoS).
To solve the problems, a research team led by Yun MA published their new research on 15 December 2024 in Frontiers of Computer Science co-published by Higher Education Press and Springer Nature.
The team proposed a server precompiling approach named WPIA to reduce DNN warm-up time in Web browsers. The team evaluated WPIA, and the evaluation results show that WPIA can reduce 84.1% of the DNN warm-up time on average and 95.3% at maximum, accelerating DNN warm-up to an order of magnitude faster, with negligible additional overhead.
In the research, they investigate the reason for the long DNN model warm-up time in Web apps and find that compiling WebGL programs into binaries takes most of the time. Inspired by this finding, they propose WPIA, an approach that reduces the DNN warm-up time in Web apps by precompiling WebGL programs offline.
WPIA collects and precompiles WebGL programs at the server side, and fetches and loads the WebGL program binaries at the browser side. WPIA merges WebGL programs to reduce WebGL binaries' size and uses a record-and-replay technique to handle the execution of precompiled WebGL programs.
They evaluate WPIA on four devices and six DNN models, and results show that WPIA can reduce 84.1% of the DNN warm-up time on average and 95.3% at maximum, accelerating DNN warm-up to an order of magnitude faster, with negligible additional overhead.

First evidence of olaparib maintenance therapy in patients with newly diagnosed homologous recombination deficient positive/BRCA wild-type ovarian cancer: real-world multicenter study
2025-01-23
Ovarian cancer, a deadly gynecologic malignancy, has seen a significant shift in its treatment paradigm with the introduction of poly (ADP-ribose) polymerase (PARP) inhibitors, which are now standard in the maintenance setting following first-line chemotherapy. This retrospective cohort study investigates the real-world effectiveness and safety of olaparib, a PARP inhibitor, in patients with newly diagnosed advanced-stage, high-grade serous ovarian cancer who are HRD positive but BRCA wild-type, a demographic less extensively explored in previous research. The primary goal was to assess the 1-year progression-free ...

Camel milk udderly good alterative to traditional dairy
In addition to being hypoallergenic, camel milk could potentially protect the gut from harmful enzymes and create healthier digestion.
New research from Edith Cowan University (ECU) has found that camel milk contained more naturally occurring bioactive peptides when compared to its bovine counterpart.
“This is a good thing. We now know that camel milk has the potential to be hypoallergenic compared to cow’s milk, but also that it has higher potential to yield bioactive peptides which can have antimicrobial ...
New, embodied AI reveals how robots and toddlers learn to understand
2025-01-23
We humans excel at generalization. If you taught a toddler to identify the color red by showing her a red ball, a red truck and a red rose, she will most likely correctly identify the color of a tomato, even if it is the first time she sees one.
An important milestone in learning to generalize is compositionality: the ability to compose and decompose a whole into reusable parts, like the redness of an object. How we get this ability is a key question in developmental neuroscience – and in AI research.
The earliest ...

Game, set, match: Exploring the experiences of women coaches in tennis
As the Australian Open continues in full swing, a new study can reveal female tennis coaches experience significantly more barriers in their profession – including discrimination and marginalisation – than their male counterparts, with fewer than half seeing themselves continuing as coaches long term.
Led by Dr Jasmine Petersen from Flinders University’s Caring Futures Institute, the study interviewed 243 Australian tennis coaches, a third of which were women, assessing their motivation and barriers towards coaching and the support they received.
“Women coaches continue ...
Significant rise in mental health admissions for young people in last decade
2025-01-23
There was a 65% increase in the number of children and young people being admitted to general acute medical wards in hospitals in England because of a mental health concern between 2012 and 2022, finds a new study led by UCL researchers.
The study, published in The Lancet Child and Adolescent Health journal and funded by the National Institute for Health and Care Research (NIHR) and the NIHR Great Ormond Street Hospital Biomedical Research Centre (NIHR GOSH BRC), analysed data on all admissions of five- to 18-year-olds to medical wards in England from April 1st 2012 to March 31st 2022.
General acute medical wards are specialised hospital wards designed to provide rapid ...
Prehab shows promise in improving health, reducing complications after surgery
2025-01-23
A new study published in The BMJ suggests that prehabilitation (also called prehab) may be able to reduce complications and length of hospitalization after surgery, while also improving quality of life and physical recovery. The systematic review and meta-analysis, which is the largest of its kind, examined data from more than 15,000 patients who participated in 186 randomized controlled clinical trials around the world.
The researchers looked at various kinds of prehab, including exercise, nutritional enhancement, psychological support, cognitive ...
Exercise and improved diet before surgery linked to fewer complications and enhanced recovery
2025-01-23
Actively preparing for major surgery by exercising and improving diet (known as “prehabilitation”) is associated with fewer complications, less time in hospital, and improved recovery and quality of life in adults, finds an analysis of clinical trials published by The BMJ today.
The researchers stress that the certainty of evidence for all comparisons was generally low to very low, but they say prehabilitation based on exercise, nutrition, or exercise combined with other components, may be beneficial.
Existing evidence suggests that prehabilitation can improve outcomes after surgery, but there’s a lack of clarity about which components, ...
SGLT-2 drug plus moderate calorie restriction achieves higher diabetes remission
2025-01-23
Adults with overweight or obesity and type 2 diabetes who are given the sodium glucose cotransporter 2 (SGLT-2) inhibitor drug dapagliflozin alongside moderate calorie restriction achieve much higher rates of remission compared with calorie restriction alone, finds a trial published by The BMJ today.
The researchers say this study provides a practical strategy to achieve remission for patients with early type 2 diabetes.
Type 2 diabetes affects over 400 million adults worldwide. It’s not necessarily a permanent condition and can be reversed by intensive weight management, ...
Could the Summerville ghost lantern be an earthquake light?
2025-01-23
Gather around, and let Susan Hough tell you the tale of the Summerville Light.
Legend has it that the strange orb sometimes seen hovering over the railroad tracks in the remote area around Summerville, South Carolina is a lantern borne by a ghost whose husband lost his head in a train accident.
But Hough, a seismologist at the U.S. Geological Survey, wonders if there might be a less ethereal but no less intriguing possibility: is the source of the Summerville Light a phenomenon known as earthquake ...
Will the U.S. have enough pain specialists?
2025-01-22
(SACRAMENTO) — Nearly a quarter of adults in the U.S. have chronic pain, but a new study from the UC Davis School of Medicine shows a concerning drop in residents applying to pain medicine fellowship programs.
The study was published in PAIN Practice. It found the number of anesthesiology residents applying for pain medicine fellowships — historically the key pool of applicants — dropped 45% between 2019 and 2023.
“While the demand for pain specialists is growing in the U.S., the pipeline of new doctors to fill these roles is drying up,” said Scott Pritzlaff, the study’s ...
