Liu's InertiaMeter tool enables real-time estimation of power grid inertia, allowing operators to prevent outages with increasing renewable energy reliance. The technology utilizes signals from pumped storage hydropower projects and low-cost grid sensors for accurate monitoring.
A recent study found significant therapeutic inertia in the treatment of women with multiple sclerosis (MS), leading to delayed or reduced use of disease-modifying treatments. The research highlights gender disparities that could impact long-term health outcomes for women of childbearing age, particularly due to concerns about pregnanc...
A Cornell University study found that online grocery carts have less variety and fewer fruits and vegetables than in-store carts, with more overlapping items between successive trips. However, online shoppers are less susceptible to unhealthy impulse buys.
A study found that a traffic light system reduced clinical uncertainty by 70% and improved treatment decisions for doctors. The system, which uses green, yellow, and red lights to indicate risk levels, was shown to decrease pupil dilation and improve treatment outcomes.
A study by Dr. Stephanie Centofanti and her team found that consuming caffeine before taking a short nap can help counteract sleep grogginess and improve alertness in night shift workers. This 'caffeine-nap' combination shows promise as a fatigue countermeasure for shift workers.
A study by RMIT University found that melodic alarms can improve alertness levels, while harsh alarm tones are linked to increased morning grogginess. The research suggests that the sound used to wake up could have important implications for people who need to perform at their peak soon after waking.
Research by Lancaster University finds that family-related considerations often trump a desire to grow among firms with multiple generations of the same family in senior roles. Non-active family members as major shareholders and non-family members on boards encourage growth, while active family members are more conservative and risk-av...
The new collimator sets up Newtonian mechanics that could be adapted for practical use in beam-driven gyroscopes, helping track motion and changes in location. It also enables experimental physicists to create complex quantum states, and its beams are streams of unwavering inertia due to the atoms' mass and momentum.
An observational study by researchers at Karolinska Institutet in Sweden found that bariatric surgery is associated with fewer complications during childbirth, including reduced risk of post-term delivery or uterine inertia. The study compared deliveries in women who had undergone weight loss after bariatric surgery to those who did not.
Scientists are exploring a new propulsion idea that could eliminate fuel costs and make interplanetary travel easier. Dr. Mike McCulloch's quantised inertia theory predicts that objects can be pushed by differences in Unruh radiation in space.
Scientists have developed a new algorithm that can mirror a microgrid's inertia by adjusting the photovoltaic system's direct current. The solution aims to make microgrids work like large power grids with high inertia, improving stability and reliability.
A new study by B. Ubbo Felderhof reveals that even when thrust and drag average out over a period, periodic shape deformations can lead to net motion in microorganisms and animals, improving upon popular explanations of swimming and flying mechanisms. The research provides an important conceptual clarification of flow theory and has po...
Researchers propose using nudges to influence patients' decisions to enroll in trials, leveraging psychology and economics. Strategies include conveying participant numbers, default enrollment in low-risk trials, and financial incentives.
A University of Leicester study found that people with Type 2 diabetes wait an average of 3.7 years for increased treatment, leading to a failure to achieve tight blood sugar control. Clinical inertia is being identified as the major contributor to this issue.
Physicists have found a simple formula for the maximum mass of neutron stars, which depends on their rotation rate. The research, published in Monthly Notices of the Royal Astronomical Society, suggests that rotating neutron stars can support masses up to 20% higher than non-rotating ones.
A new simplified model predicts patterns that form from honey-like fluids, influenced by the ratio between fluid speed on impact and conveyor belt speed. The team's findings match previous experimental results and may be used to optimize manufacturing processes for nonwoven materials.
Researchers at Disney Research Zurich have developed an algorithm that can optimize the mass distribution within objects to enable a stable spin around a desired axis, applicable to various shapes and materials. The approach has potential applications beyond customized designs for spinning toys.
Researchers led by Paulo E. Arratia at the University of Pennsylvania discovered that turbulence can arise in non-Newtonian fluids, such as blood and fracking liquids, without requiring significant inertia. This finding has significant implications for understanding fluid dynamics on small scales.
A study by the University of Colorado at Boulder found that older adults taking zolpidem are significantly more likely to experience balance problems and cognitive impairments. Younger adults also showed significant cognitive impacts from sleep inertia, highlighting a need for further research on this topic.
Researchers found that cats, regardless of size, use a delicate balance between gravity and inertia to lap milk efficiently. The cat's tongue moves in a subtle motion, creating a column of liquid that is then pinched off by the cat's chin.
Scientists warn that avoiding dangerous climate change requires steep cuts in carbon dioxide emissions from power plants, cars, and other devices. New research suggests that existing infrastructure is less of a threat to climate than expected, but building the right low-carbon energy technologies now is crucial.
Calculations by Dr. Eduardo Zorita and colleagues estimated the likelihood of warm record years after 1990 being an accident is extremely low, suggesting external influences
Researchers find that wing shape and flapping motion are crucial for efficient flight, contradicting the assumption that nature is always efficient. Dr. Jim Usherwood's study suggests that mimicking nature's designs can lead to flawed results, highlighting the importance of understanding aerodynamics in biomimetics.
A study of British doctors and health professionals found they struggle with language barriers, cultural understanding, and uncertainty about how to care for patients from ethnic minority backgrounds. This uncertainty can lead to hesitancy and inertia in practice, contributing to inequalities in care.
A new CU-Boulder study found that morning grogginess can cause diminished short-term memory, counting skills, and cognitive abilities. Cognitive deficiencies following 24 hours of sleep deprivation have previously been shown to be comparable to the effects of alcohol intoxication.
