In Applied Physics Reviews, researchers from Tsinghua University work to break through the difficulties of robotic recognition of various common, yet complex, items. Their layered sensor is equipped with material detection at the surface and pressure sensitivity at the bottom, with a porous middle layer sensitive to thermal changes.
In Review of Scientific Instruments, researchers from the University at Buffalo develop a tool for measuring the viscosity of lava that could increase our understanding of molten rock as well as better improve models of its movement, giving authorities crucial guidance for keeping people safe.
Plant hydraulics drive the biological process that moves fluids from roots to plant stems and leaves, creating streaming electric potential, or voltage, in the process.
As communities are flooded with pickleball courts to satiate the hunger for the snack-named game, HOAs and city councils face litigation by those whose lives are disrupted by pickleball’s din. The sport is uniquely noisy due to the hard paddles and balls, and the popping sound the game produces is sharp and persistent. Charles Leahy used his legal expertise and mechanical engineering experience to investigate how communities respond to the pickleball problem. Leahy will present his findings and recommendations for limiting pickleball noise at the 186th ASA Meeting.
Noise-canceling headphones automatically identify background sounds and cancel them out for much-needed peace and quiet. However, typical noise-canceling fails to distinguish between unwanted background sounds and crucial information, leaving headphone users unaware of their surroundings.
At the Toronto Pearson International Airport, airplane traffic dropped by 80% in the first few months of lockdown during the COVID-19 pandemic., and in early 2020, the NVH-SQ Research Group out of the University of Windsor surveyed residents living around the airport to gauge how their annoyance levels changed with the reduction in noise.
Sarcasm is notoriously tricky to convey through text, and the subtle changes in tone that convey sarcasm often confuse computer algorithms as well, limiting virtual assistants and content analysis tools.
Researchers from Binghamton University investigated how spiders listen to their environments through webs and found that the webs match the acoustic particle velocity for a wide range of sound frequencies.
Hockey players are famous for their distinctive jargon, but while researching this phenomenon, linguist and hockey player Andrew Bray realized another interesting pattern in hockey speech: American hockey players adopted aspects of Canadian English pronunciations.
Pickups can be seen as the “heart” of the electric guitar, turning vibrations from the strings into electricity for sound. The details of how the pickup coil is wound has a significant impact on the resulting sound of the instrument, and variables such as the type and thickness of the wire, the winding pattern, the shape and size of the pickup, and even the type of magnets used can all influence the guitar’s sound.
In the emperor penguin courtship call, male vocalizations are composed of long, slow bursts with lower frequency tones than the female version. But calls of SeaWorld San Diego male penguin E-79 defied this binary. Also unusual was this penguin’s male companion, E-81. The pair “kept company” and sometimes exhibited ritual courtship displays.
At Image Creators salon in Maryland, employees and customers noticed they had to work hard to understand each other’s words, but they couldn’t put their finger on exactly why.
In traditional Indigenous Southern Plains culture, a love story begins with an original ballad performed on the flute. In order to win a lover’s affection, and respect among the tribe, each pursuer must compose one good flute serenade.
Fishers are typically unaware if a sea turtle is caught in their net until it’s completely pulled out of the water. However, releasing sea turtles without veterinary evaluations can be harmful.
At the University of Alberta, researchers explored how intense ultrasound can release biological indicators of disease from cells. These biomarkers can help identify different types of cancer and inform the subsequent therapy.
Understanding how mucus changes, and what it changes in response to, can help diagnose illnesses and develop treatments. In APL Bioengineering, researchers develop a system to grow mucus-producing intestinal cells and study the characteristics of the mucus in different conditions.
In APL Bioengineering, researchers used a breast cancer cell line panel and primary tumor explants from breast and cervical cancer patients to examine two different cellular contractility modes: one that generates collective tissue surface tension that keeps cell clusters compact and another, more directional, contractility that enables cells to pull themselves into the extracellular matrix.
The Acoustical Society of America and the Canadian Acoustical Association will host three press conferences Tuesday, May 14, as part of the 186th ASA Meeting/Acoustics Week, which runs May 13-17. The in-person presentations will also be livestreamed and recorded.
One group commonly misunderstood by voice technology are individuals who speak African American English, or AAE.
In Applied Physics Letters, researchers use laser treatments to transform ordinary cork into a powerful tool for treating oil spills. They tested variations of a fast-pulsing laser treatment, closely examining the nanoscopic structural changes and measuring the ratio of oxygen and carbon in the material, changes in the angles with which water and oil contact the surface, and the material’s light wave absorption, reflection, and emission across the spectrum to determine its durability after multiple cycles of warming and cooling.
