Branch-Cooperative OSNet for Person Re-Identification [PDF]

arXiv, 2020
Multi-branch is extensively studied for learning rich feature representation for person re-identification (Re-ID). In this paper, we propose a branch-cooperative architecture over OSNet, termed BC-OSNet, for person Re-ID. By stacking four cooperative branches, namely, a global branch, a local branch, a relational branch and a contrastive branch, we ...

Transformation of 3D Metal–Organic Frameworks into Nanosheets with Enhanced Memristive Behavior for Electronic Data Processing

Advanced Science, EarlyView.
The design of 3D MOFs based on neutral and anionic ligands allows implementing the structural transformation from 3D to 2D nanosheets with improved insulating properties, utilized for efficient ultrathin memristive elements. Abstract The transition from three‐dimensional (3D) to two‐dimensional (2D) semiconducting and insulating materials for micro ...

Branched projective structures, branched SO(3,C)-opers and logarithmic connections on jet bundle [PDF]

arXiv, 2020
We study the branched holomorphic projective structures on a compact Riemann surface $X$ with a fixed branching divisor $S\, =\, \sum_{i=1}^d x_i$, where $x_i \,\in\, X$ are distinct points. After defining branched ${\rm SO}(3,{\mathbb C})$--opers, we show that the branched holomorphic projective structures on $X$ are in a natural bijection with the ...

Unveiling Structural Heterogeneity and Evolutionary Adaptations of Heteromultimeric Bacterioferritin Nanocages

Advanced Science, EarlyView.
This study explores the structural heterogeneity and evolutionary adaptations of heteromultimeric bacterioferritins. Hetero‐Bfrs, evolved from either a homo‐Bfr or Ftn by gene duplications, differ from homo‐Bfrs substantially in the mechanisms underpinning iron oxidation and reduction despite high similarity in overall structure.

ON THE EVOLUTIONARY HISTORY OF PROGENITORS OF EHBS AND RELATED BINARY SYSTEMS BASED ON ANALYSIS OF THEIR OBSERVED PROPERTIES

Odessa Astronomical Publications, 2007
It has been shown quite recently (Morales-Rueda et al., 2003) that dB stars, extreme horisontal branch (EHB) objects in high probability all belong to binary systems.

Laminar Branched Surfaces in 3-manifolds [PDF]

Geom. Topol. 6 (2002) 153-194, 2002
We define a laminar branched surface to be a branched surface satisfying the following conditions: (1) Its horizontal boundary is incompressible; (2) there is no monogon; (3) there is no Reeb component; (4) there is no sink disk (after eliminating trivial bubbles in the branched surface).

Deciphering Auditory Hyperexcitability in Otogl Mutant Mice Unravels an Auditory Neuropathy Mechanism

Advanced Science, EarlyView.
By investigating auditory hyperexcitability in a mouse model for hereditary deafness, this study identified a subpopulation of afferent neurons of the auditory nerve marked by Otogl expression. Despite their apparently normal hearing, Otogl+/− mice display poor activation of afferent neurons processing loud sounds and an elevation of the middle the ear

Dynamic data‐driven computation method for the number of waiting passengers and waiting time in the urban rail transit network

IET Intelligent Transport Systems, Volume 17, Issue 1, Page 165-179, January 2023., 2023
Abstract Excess passengers gathering on the urban rail transit platform in a short time brings huge security risks to passengers and the daily operation of urban rail transit. However, the real‐time monitoring method of passenger flows, which relies on manual methods, cannot satisfy the requirement of daily operations at the network level anymore. This

Asteroseismology Sheds Light on the Origin of Carbon-deficient Red Giants: Likely Merger Products and Linked to the Li-rich Giants

The Astrophysical Journal, 2023
Carbon-deficient red giants (CDGs) are a peculiar class of stars that have eluded explanation for decades. We aim to better characterize CDGs by using asteroseismology (Kepler, TESS) combined with spectroscopy (APOGEE, LAMOST), and astrometry (Gaia).

ROS‐Activated Nanohydrogel Scaffolds with Multi‐Factors Controlled Release for Targeted Dual‐Lineage Repair of Osteochondral Defects

Advanced Science, EarlyView.
ROS‐activated nanohydrogels composite bilayer scaffolds are rationally designed for targted dual‐lineage repair of osteochondral defects. The as‐prepared nanohydrogel scaffolds provided 3D culture and induced dual‐lineage differentiation of BMSCs in vitro, efficiently inhibited early‐stage inflammation by rapidly releasing DS and improved cartilage and
