Correlations between mass, stellar kinematics and gas metallicity in EAGLE galaxies [PDF]
, 2019 The metallicity of star-forming gas in galaxies from the EAGLE simulations increases with stellar mass. Here we investigate whether the scatter around this relation correlates with morphology and/or stellar kinematics. At redshift $z=0$, galaxies with more rotational support have lower metallicities on average when the stellar mass is below $M_\star ...

A Convoy of Magnetic Millirobots Transports Endoscopic Instruments for Minimally‐Invasive Surgery
Advanced Science, EarlyView.The first electrocautery procedure performed by a team of millirobots (TrainBots) is presented. Enhanced with optimized feet, millirobots form a convoy to facilitate the collaborative transportation of wires and catheters through biological lumens, e.g. bile ducts. It opens up the possibility of using a team of mini‐robots in future endoscopic surgery.

VLT/VIMOS Integral field kinematics of the Giant Low Surface Brightness galaxy ESO 323-G064 [PDF]
arXiv, 2007 We studied the bulge and the disk kinematic of the giant Low Surface Brightness (LSB) galaxy ESO 323-G064 in order to investigate its dynamics and its Dark Matter (DM) content. We observed the galaxy with the integral field spectroscopy (VLT/VIMOS, in IFU configuration). Results for the gaseous kinematics (bulge and disk) and stellar kinematics (bulge)

Shared and Unique Neural Codes for Biological Motion Perception in Humans and Macaque Monkeys
Advanced Science, EarlyView.Cross‐species fMRI studies reveal distinct neural mechanisms for biological motion (BM) processing. In humans, the posterior superior temporal sulcus (hpSTS) selectively responds to conspecific BM, while monkeys process BM from both species in the middle temporal area (MT).

Radial Kinematics of Isolated Elliptical Galaxies [PDF]
, 2006 Ellipticals in very low density environments are extremely rare but hold important clues about galaxy formation and evolution. In this paper we continue our study of isolated elliptical galaxies, presenting results on the radial stellar kinematics for 13 isolated early-type galaxies.

Rotation‐Based Snap‐Fit Mechanical Metamaterials
Advanced Science, EarlyView.This article introduces a rotational snap‐fit structure composed of a circular cantilever beam snap‐fit and a circular groove. It demonstrates multistability during the rotation process. This innovative design has potential applications in various fields, such as mechanical metamaterials, shape deformation, and robotic grippers, showcasing its ...

Detecting Triaxiality in the Galactic Dark Matter Halo through Stellar Kinematics II: Dependence on Dark Matter and Gravity Nature [PDF]
, 2015 Recent studies have presented evidence that the Milky Way global potential may be nonspherical. In this case, the assembling process of the Galaxy may have left long lasting stellar halo kinematic fossils due to the shape of the dark matter halo, potentially originated by orbital resonances.

Dynamic Molecular Cocrystals with Alkyl Chain Dependent Thermosalient Phase Transitions
Advanced Science, EarlyView.A series of cocrystals containing 5‐fluorocytosine and fatty acids with varying alkyl chain lengths are synthesized, demonstrating a systematic modulation of thermosalient phase transition temperatures across a broad range (≈100 K). This study reveals a linear correlation between interlayer hydrophobic interactions and transition temperatures, offering

Superchaotropic Nano‐ion Binding as a Gelation Motif in Cellulose Ether Solutions
Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023 Nano‐ions, like polyoxometalates and boron clusters, co‐assemble strongly with non‐ionic solutes in water driven by the chaotropic effect. Here, nano‐ion assembly with non‐ionic cellulose ethers (CE) is shown to result in unprecedented thickening effects and gelation of CE‐solutions. An interplay of electrostatic repulsion and attraction between chains

A Gemini/GMOS Study of Intermediate Luminosity Early-Type Virgo Cluster Galaxies. I. Globular Cluster and Stellar Kinematics [PDF]
arXiv, 2015 We present a kinematic analysis of the globular cluster systems and diffuse stellar light of four intermediate luminosity (sub-$L^{\ast}$) early-type galaxies in the Virgo cluster based on Gemini/GMOS data. Our galaxy sample is fainter ($-23.8
