MFSnet: a multi-scale feature screening network for chicken counting in dense environments
ABSTRACT 1. Machine-vision-based chicken counting is a highly efficient approach. Nonetheless, in scenarios with high breeding densities, chickens in the captured images frequently overlap with one another. This research addressed the challenge of accurately counting chickens within a free-range chicken coop in densely environments. It proposes a chicken-counting network specifically designed for dense scenarios, namely MFSnet. 2.
Achieving constant magnetic permeability in Fe-based nanocrystalline alloys by Ni alloying and magnetic-field annealing for high DC bias capability and low coercivity
Topics Magnetic anisotropy, Magnetic hysteresis, Magnetic materials, Magnetization dynamics, X-ray diffraction, Transformer, Electrical properties and parameters, Electromagnetism, Magnetic fields, Nanomaterials Nanocrystalline alloys are becoming the preferred choice over conventional soft magnetic materials such as ferrite and silicon steel because of their enhanced magnetic performance.
Effects of nitrogen flow on the microstructure and mechanical properties of (TiZrNbMoTa)N high-entropy nitride films by magnetron sputtering
With the rapid development of dry-cutting technology, a variety of coating materials have been applied to tools to meet the requirements of machining in harsh environments. However, common coated tools are prone to wear and poor machining quality in dry-cutting environments.1 Therefore, it is urgent to explore new high-performance materials. High-entropy alloys (HEAs) were first proposed and prepared by Yeh et al.
Tunable electromagnetic properties via dealloying in FeCoNiCuAl high-entropy alloys for efficient electromagnetic-wave absorption
Topics Electromagnetism, Corrosion, Crystal structure, Dielectric properties, Alloys, Materials synthesis and processing, Materials properties, Porous media, X-ray diffraction, Chemical solutions Electromagnetic radiation has become increasingly serious due to numerous electronic device applications, which threaten human health and communication security.1–4 Electromagnetic-wave (EMW) absorbing materials, which can dissipate EMW energy, have attracted much attention for addressing...

Reversible switchable wettability of intrinsic micro/nanostructured pollen microcarriers via pH-induce from superhydrophobicity to superhydrophilicity
In recent years, the design and preparation of microcapsules with functional properties have attracted great interest from researchers in the application of material science and biotechnology [1]. Microencapsulation design can achieve excellent drug stability, targeting, and controlled release performance, so it has received extensive attention in the field of biomedicine [2], [3], [4], [5].
Acoustic metamaterial absorbers: The path to commercialization
Two decades after the initiation of the acoustic metamaterial field, a clear bifurcation is evident: While one direction points to the continued pursuit of novel phenomena,1–9 mostly through topological structures,10–13 the other points to practical applications on those problems difficult to resolve through conventional means, with the ultimate goal of commercialization. This article intends to address the latter, in the area of acoustic absorption.
"La bohème" di Leopoli al Festival Puccini: 150 artisti ucraini
Una trasferta emblematica il cui ricavato andrà a sostegno del sofferente teatro di Leopoli, intitolato a Solomea Krusceniski, leggenda della lirica, la Callas dell’Ucraina Quella che il 23 agosto andrà in scena al Gran Teatro di Torre del Lago è La bohème del Teatro di Leopoli: 150 artisti, musicisti, cantanti, tecnici, che dall’Ucraina arriveranno nella patria di Puccini con un capolavoro capace di attraversare i confini, anche nel mezzo della guerra.
Dynamic monitoring of CD45-/CD31+/DAPI+ circulating endothelial cells aneuploid for chromosome 8 during neoadjuvant chemotherapy in locally advanced breast cancer
Background: Neoadjuvant chemotherapy (NCT) is the standard treatment for patients with locally advanced breast cancer (LABC). Circulating endothelial cells (CECs) are cancer biomarkers and crucial for angiogenesis. The relationship between NCT treatment and the number of aneuploid CECs in LABC has not been previously investigated. The aim of this study was to verify this relationship, and to estimate the clinic value of aneuploid CECs in LABC patients with different NCT responses.

毛细血管畸形 (CMs) 也被称为酒色斑,是一种胎记,在每 1000 名新生儿中影响大约 3 至 5 人。酒色巨唇 (PWM) 是同时导致唇增大的 CMs。据报告,酒色斑是由一种称为 GNAQ 的蛋白突变导致的,这项由中华人民共和国研究者进行的研究旨在探索不同 (PWM) 组织[如皮肤、粘膜(例如口腔和鼻腔内的组织)]、腺体和肌肉中此突变的发生频率。作者们发现,这种称为 GNAQ (R183Q) 的突变不存在于腺体标本中,但分别在 90% 的皮肤、95% 的粘膜和 95% 的肌肉样本中检出。这项研究还发现,GNAQ 突变频率和临床特征之间呈正相关,意味着突变与症状有关,尤其对于粘膜而言。因此,作者们假设,唇粘膜中的 GNAQ 突变(无论皮肤有无基础酒色斑)可被用作早期 PWM 的预测标志物。作者们指出,如果医生认为患者可能有基础酒色斑,进行粘膜活检(对一小块皮肤标本进行检查)可能有助于更早发现 PWM 和更早开始治疗。活检是实用方便的,愈合迅速,不会留疤。
GNAQ mutation in port‐wine macrocheilia
Capillary malformations (CMs), also called port‐wine stains, are a type of birthmark which affect about 3 to 5 out of every 1000 newborn babies. Port‐wine macrocheilia (PWM) are CMs that also cause the lips to enlarge.
Somatic GNAQ mutation in different structures of Port‐wine Macrocheilia
The etiology of Port‐wine macrocheilia (PWM), which involves a congenital, progressive capillary malformation that results in soft tissue hypertrophy in the lips, has not yet been fully elucidated. We sought to investigate frequencies of GNAQ mutation in different tissues from patients with PWM, including skin, mucosa, gland and muscle, using samples obtained during cheiloplasty.

The work and challenges of care managers in the implementation of collaborative care: A qualitative study
In collaborative care models for anxiety and depression, the care manager (CM), often a mental health nurse, has a key role. However, the work and challenges related to this role remain poorly investigated. To explore CMs’ experiences of their work and the challenges they face when implementing their role in a collaborative care intervention in the Capital Region of Denmark.
