Machine Learning the Dark Matter Halo Mass of the Milky Way
Although numerous dynamical techniques have been developed to estimate the total dark matter halo mass of the Milky Way, it remains poorly constrained, with typical systematic uncertainties of 0.3 dex. In this study, we apply a neural network-based approach that achieves high mass precision without several limitations that have affected past approaches;

Capacitive Pixelated CMOS Electronic Nose
Advanced Electronic Materials, EarlyView.A 1024‐pixel CMOS capacitive E‐nose with inkjet‐printed MOFs and polymer layers yields gas‐specific capacitance fingerprints under humid conditions, discriminating toluene from 2‐butanone at low power. ABSTRACT Although some of the human senses can nowadays be replaced by low‐cost electronic sensors such as microphones and image sensors, a compact low ...

The Astrophysical JournalRecent measurements of the Milky Way rotation curve found a sharp decline at around 15–20 kpc from the center of the Galaxy, suggesting that the Galactic dark matter halo is much less massive than predicted by other dynamical tracers.

Ionic Elastomer Interface for Low‐Pressure and Durable All‐Solid‐State Batteries
Advanced Energy Materials, EarlyView.This work reports an ionically conductive elastomer that enables stable all‐solid‐state batteries（ASSBs）under low external pressure. The soft elastomeric matrix, integrated with a LiG3‐based conductive phase(lithium bis(trifluoromethanesulfonyl)imide and triethylene glycol dimethyl ether), simultaneously delivers high ionic conductivity and mechanical ...

The Cost of a Nutritious Diet in Cafeterias: Evidence From US Military Dining Facilities
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Providing nutritious meals in institutional settings with financial constraints, such as military dining facilities, is challenging. The US Department of War (DoW) and US Department of Agriculture (USDA) collaborated to modernize the Basic Daily Food Allowance (BDFA) using an optimization model that incorporates service members' consumption ...

Diffuse Light in Milky Way–like Haloes
The Astrophysical Journal LettersWe investigate the diffuse light (DL) content of dark matter haloes in the mass range $11.5\leqslant \mathrm{log}{M}_{\mathrm{halo}}\leqslant 13$ , a range that also includes the dark matter halo of the Milky Way, taking advantage of a state-of-the-art ...

First measurement of the triaxiality of the inner dark matter halo of the Milky Way
Astronomy & AstrophysicsContext. Stellar streams are particularly sensitive probes of the mass distribution of galaxies. Aims. In this work, we focus on the Helmi streams (HS), the remnants of an accreted dwarf galaxy orbiting the inner Milky Way. We examined their peculiar dynamical properties in depth, and used these to provide tight constraints on the Galactic potential ...

The HCMV‐encoded miR‐UL36‐3p promotes angiogenesis of endothelial cells by downregulating FOXO3
Animal Models and Experimental Medicine, EarlyView.This illustration shows the role of hcmv‐miR‐UL36‐3p in endothelial cell angiogenesis. During productive infection, endothelial cells express HCMV‐encoded miRNAs. Viral hcmv‐miR‐UL36‐3p promotes endothelial cell proliferation, migration, and capillary tube formation by directly targeting and downregulating FOXO3. The pro‐angiogenic activity of hcmv‐miR‐

Archaeological Prospection, EarlyView.ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.
