As the world steadily recovers from the COVID-19 pandemic, managing large gatherings becomes a critical concern for ensuring crowd safety. The crowd-crush disaster in Seoul in 2022 highlights the need for effective predictive crowd management techniques. In this study, an empirical analysis of this incident is conducted using data from various sources, and model-based simulations are created to replicate hazardous crowd conditions in high-risk areas.

Even when pain control is implemented, calves may experience pain for days after hot-iron disbudding. Whether calves seek pain relief post-disbudding offers a novel approach to assessing pain in these animals. By employing an approach-aversion paradigm, we explored the ability of cold therapy to provide immediate pain relief in disbudded calves. Calves were habituated to the manual placement of a cool or ambient pack on... Читать дальше...

Evaluating the drivers of B2B performance: An empirical analysis based on Alibaba

by Miao Feng, Haoran Si, Yang Li, Junrui Zhang

The rapid development of B2B has brought about fierce competition among suppliers, and how to gain customer attention and improve performance has become a common concern in academia and industry. This study examined the drivers and mechanisms of B2B performance from an enterprise capability perspective. We collected transaction and enterprise data from 325 suppliers on Alibaba 1688 platform and constructed a structural equation model (SEM). Results showed that supplier service capability...

ASATrans: Adaptive spatial aggregation transformer for cervical nuclei segmentation on rough edges

by Hualin Sun, Shengyao Hu

The main characteristic of cervical cytopathy is reflected in the edge shape of nuclei. Existing computer-aided diagnostic techniques can clearly segment individual nuclei, but cannot clearly segment the rough edges of adherent nucleus. Therefore, we propose an effective method (ASATrans) to accurately segment rough cervical nuclei edges by exploring adaptive spatial aggregation methods. ASATrans creates a Multi-Receptive Embedding Layer that samples patches using diverse-scale kernels. Читать дальше...

Currency risk analysis of belt and road initiative countries

by Mengyang Li, Wencui Liu, Lei Wang

The UN’s Sustainable Development Goals (SDGs) highlight the role of debt sustainability in achieving sustainable development. China’s Belt and Road Initiative (BRI) is an international cooperation effort that is endorsed by over 150 countries and organizations. Given the alignment between BRI development goals and the SDGs, the issue of debt sustainability in BRI countries warrants attention. While existing studies focus on sovereign risk in debt sustainability... Читать дальше...

Identifying cell states in single-cell RNA-seq data at statistically maximal resolution

En

by Pascal Grobecker, Thomas Sakoparnig, Erik van Nimwegen

Single-cell RNA sequencing (scRNA-seq) has become a popular experimental method to study variation of gene expression within a population of cells. However, obtaining an accurate picture of the diversity of distinct gene expression states that are present in a given dataset is highly challenging because the sparsity of the scRNA-seq data and its inhomogeneous measurement noise properties. Although a vast number of different methods... Читать дальше...

Uncovering the hidden complexity of multicellular magnetotactic bacteria

by Kayla S. Stoy, William C. Ratcliff

Multicellular magnetotactic bacteria (MMB) have a surprisingly complex multicellular lifestyle. A new study in PLOS Biology combines genomics, microscopy, and isotopic labeling to show that MMB form obligately multicellular consortia of genetically diverse cells with rudimentary division of labor. Multicellular magnetotactic bacteria (MMB) have a surprisingly complex multicellular lifestyle. This Primer explores a new study in PLOS Biology which combines genomics... Читать дальше...
