Handling x-rays at high speed
As x-ray lasers gain the ability to fire at ever-increasing speeds, current data systems need to increase their effectiveness to handle “these type[s] of facilities, especially for high throughput applications.” In this paper, the authors propose “a machine-learning algorithm to automatically extract” relevant data. The paper also covers “the feasibility of using this framework at high data volume.” See the full list of authors and read their research paper, “Testing the data framework for an AI algorithm in preparation for high data rate X-ray facilities,” at ArXiv.

Balloon-powered telescope SuperBIT looks at the ‘wrong’ end of the spectrum
In studying dark matter, cosmologists and astronomers rely on observations of galaxies seen through or around the material. Traditionally, these observations have been made of “red-shifted” galaxies, those moving away from the Earth. This paper provides an explanation for why the Super-pressure Balloon-borne Imaging Telescope (SuperBIT) will instead observe blue-shifted galaxies, those moving toward the earth. See the full list of authors and read their paper, “Weak lensing in the blue: a counter-intuitive strategy for stratospheric observations,” at ArXiv.

‘Electric-Magnetic Duality in a Class of G₂-Compactifications of M-theory’
“We study electric-magnetic duality in compactifications of M-theory on twisted connected sum (TCS) G2 manifolds via duality with F-theory. Specifically, we study the physics of the D3-branes in F-theory compactified on a Calabi-Yau fourfold Y, dual to a compactification of M-theory on a TCS G2 manifold X. N=2 supersymmetry is restored in an appropriate geometric limit.” See the full list of authors and read the paper at ArXiv.

‘Neuronal temperature perception induces specific defenses that enable C. elegans to cope with… hydrogen peroxide’
“Hydrogen peroxide is the most common reactive chemical that organisms face on the microbial battlefield. The rate with which hydrogen peroxide damages biomolecules required for life increases with temperature, yet little is known about how organisms cope with this temperature-dependent threat. Here, we show that Caenorhabditis elegans nematodes use temperature information perceived by sensory neurons to cope with the temperature-dependent threat of hydrogen peroxide. … This is the first example of a multicellular organism inducing their defenses to a chemical when they sense an inherent enhancer of the reactivity of that chemical.” Find the paper and the full list of authors at ELife…

For nonprofit hospitals, customers expect more than core services
When corporations increase “social responsibility” activities, customers should show increased appreciation for those companies—but this isn’t always the case. The authors of “The Value of Core and Noncore Activity Fit for Corporate Social Responsibility: An Expectation-Based Study of Nonprofit Hospitals” argue that corporate social responsibility can be understood along the axes of “core”—activities directly related to the business—and “noncore” functions—activities outside the business’s regular operations. Find the paper and the full list of authors in the Journal of Public Policy and Marketing.

Paper presents novel method for understanding scattering of electromagnetic fields
In this pre-print, Feiguin et al. present an alternative solution to understanding the “scattering cross-section” of electromagnetic fields, using a “time-dependent momentum-resolved” approach. This method “does not require a full set” of quantum states to solve. The authors argue that “this powerful formulation overcomes all the hurdles imposed by previous methods.” See the full list of authors and read “A time-dependent momentum-resolved scattering approach to core-level spectroscopies” at Research Square.

Paving the way to stronger nanowires
Multiple fragmentation patterns are possible in nanowires. Alain Karma and PhD. candidate Nan Wang used “phase-field simulations [to] show that fragmentation of faceted nanowires with cubic crystal symmetry may occur by a finite-amplitude nonlinear instability.” These results “provide the theoretical foundation to predict nanowire stability as a function of length and surface energy in diverse applications,” including future technologies. Read their research paper “Fragmentation of faceted crystalline wires” at Physical Review Materials.

‘Mechanisms of Isoform-Specific Residue Influence on GTP-Bound HRas, KRas, and NRas’
“HRas, KRas, and NRas are GTPases with a common set of effectors that control many cell-signaling pathways, including proliferation through Raf kinase. Their G-domains are nearly identical in sequence, with a few isoform-specific residues that have an effect on dynamics and biochemical properties. Here, we use accelerated molecular dynamics (aMD) simulations consistent with solution x-ray scattering experiments to elucidate mechanisms through which isoform-specific residues associated with each Ras isoform affects functionally important regions connected to the active site.” Find the paper and the full list of authors at Biophysical Journal.

‘Compressive Stress Drives Adhesion-Dependent Unjamming Transitions in Breast Cancer Cell Migration’
This article examines cellular unjamming, “the collective fluidization of cell motion… linked to many biological processes, including development, wound repair, and tumor growth.” Because of the complex, linked effects between various cellular mechanisms, “the role of compressive stress in unjamming transitions during cancer progression remains unknown. Here, [the authors] investigate which mechanism dominates in a [single] dense, mechanically stressed” layer. Their findings add nuance to models of “collective cell motion in tumor development and breast cancer progression.” Find the paper and the full list of authors at Frontiers in Cell and Developmental Biology.
