Catalytically Active Light Printed Microstructures

Advanced Materials, EarlyView.
The fabrication of micro‐ and macro‐scale 3D‐printed multi‐material structures incorporating photocatalytically active Ru(II) sites using a dual‐function photoresin is introduced. The system utilizes a Ru(II)‐functionalized monomer, enabling the assembly of 3D structures with commercially available crosslinkers.

Ottoman-Flagged Ships, 1830s–1860s: Hull, Rig, and Geography

Drassana, 2020
This paper presents major hull and rig types among Ottoman-flagged merchant ships from the 1830s to the 1860s and discusses the effects of nautical and climatic conditions on the physical features of merchant ships. The statistics demonstrate that brigs,

Synthesis and analysis of small molecules to restrain the function of tissue factor within tumour cells

Frontiers in Bioscience-Landmark, 2021
Introduction: The restriction of prolyl-protein cis/trans isomerase 1 (Pin1) activity has been shown to prevent the release of tissue factor (TF) leading to the accumulation of the latter protein within the cell.

On Borel Hull Operations

Real Analysis Exchange, 2015
We show that some set-theoretic assumptions (for example Martin's Axiom) imply that there is no translation invariant Borel hull operation on the family of Lebesgue null sets and on the family of meager sets in (in R^n). We also prove that if the meager ideal admits a monotone Borel hull operation, then there is also a monotone Borel hull operation on ...

Driving Micro‐Objects Using Optical Force due to Fluorescence Emission From Molecules

Advanced Optical Materials, EarlyView.
Emission of fluorescence from a micro‐object in a specific direction is expected to generate an optical force driving the object in the opposite direction of the emission, like a rocket. To demonstrate this ‘photon‐driven micro‐rocket’, we prepared dye‐doped polymer micro‐object (PMO) one surface of which was covered with metallic film; the PMO ...

Chitosan, Gelatine, and Cellulose Based Hydrogels for the Removal of Potentially Toxic Elements from Aquaculture Water: A Comparative Study

Advanced Sustainable Systems, EarlyView.
Hydrogels made of chemically modified biopolymers are easy to prepare and cost‐effective, they have proven to be effective materials for the simultaneous removal of seven potentially toxic elements (PTEs) from ultrapure and real water samples. The cellulose‐based one seems the best for single treatments while the gelatine‐based one seems the most ...

Potentials for (p,0) and (1,1) supersymmetric sigma models with torsion

, 1993
Using (1,0) superfield methods, we determine the general scalar potential consistent with off-shell (p,0) supersymmetry and (1,1) supersymmetry in two-dimensional non-linear sigma models with torsion. We also present an extended superfield formulation of

Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

Advanced Theory and Simulations, EarlyView.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design

JA‐Mediated Regulation of Amino Acid Homeostasis Adjusts Metabolic Flux and Enhances Spider Mite Tolerance via the SlJAZ8‐SlWRKY57‐SlAVT6s Module in Tomato

Advanced Science, EarlyView.
This study elucidates a novel SlJAZ8‐SlWRKY57‐SlAVT6A/SlAVT6B module that effectively channels metabolic flux from primary to secondary metabolism, impacting plant growth, development, and resistance. Two novel vacuolar amino acid exporters, SlAVT6A and SlAVT6B, fine‐tunes trichomes, terpenes, and gibberellins, bolstering spider mite resistance.

Convex hulls of spheres and convex hulls of convex polytopes lying on parallel hyperplanes [PDF]

, 2011
Given a set $\Sigma$ of spheres in $\mathbb{E}^d$, with $d\ge{}3$ and $d$ odd, having a fixed number of $m$ distinct radii $\rho_1,\rho_2,...,\rho_m$, we show that the worst-case combinatorial complexity of the convex hull $CH_d(\Sigma)$ of $\Sigma$ is $\
