Noninvasive ultrasound technique can spot bad batteries before they malfunction
A recent uptick in battery-related fires has drawn attention to the challenge of identifying defects that can cause these catastrophic malfunctions, but are rarely obvious to the naked eye. In hopes of preventing the dangerous glitches that can cause batteries to overheat and catch fire, researchers from Drexel University have developed a standard testing process to give manufacturers a better look at the internal workings of batteries.

Triangular and tetrahedral number differences of sumset sizes in additive number theory
The study of sums of finite sets of integers has mostly concentrated on sets with very small sumsets (Freiman's theorem and related work) and on sets with very large sumsets (Sidon sets and $B_h$-sets). This paper considers the full range of sumset sizes of finite sets of integers and an unexpected pattern (related to the triangular and tetrahedral numbers) that appears in the distribution of popular sumset sizes of sets of size 4.

Rotating frames from quantum deformed spacetime
In a sense of deformation quantization, noncommutative (NC) geometry introduces a quantum structure of spacetime. Using the twist-deformation formalism, we show that the dynamical effects of spacetime noncommutativity can amount to a transition to a rotating frame of reference. In particular, we study the dynamics of charged matter (scalars and spinors) on the background of Melvin's electric universe in the framework of NC gauge field theory. Melvin's electric/magnetic universe is a static, axi…

Don't Leave Me This Way (ORIGINAL) by Harold Melvin & The Blue Notes, Teddy Pendergrass 1975 #PlayItLoudPlayItProud :-)

Wimbledon was forced to explain yet another issue with the live electronic line-calling system on Tuesday after it malfunctioned again -- only a day after it had expressed confidence that the problems that led to an embarrassing error on Sunday had been fixed.
The latest incident occurred in the quarter-final between Taylor Fritz and Karen Khachanov.
Serving at 0-15 in the opening game of the fourth set, Fritz missed his first serve, which was correctly called out.
He then …

Analysis of Langevin midpoint methods using an anticipative Girsanov theorem
We introduce a new method for analyzing midpoint discretizations of stochastic differential equations (SDEs), which are frequently used in Markov chain Monte Carlo (MCMC) methods for sampling from a target measure $π\propto \exp(-V)$. Borrowing techniques from Malliavin calculus, we compute estimates for the Radon-Nikodym derivative for processes on $L^2([0, T); \mathbb{R}^d)$ which may anticipate the Brownian motion, in the sense that they may not be adapted to the filtration at the same time…
