Stability and control benefits of coupled wing and tail morphing in kestrel wind-hovering flight explored using a robot replica [0.03%]
利用机器人复制品探索红脚隼风中悬停飞行的联锁机翼和尾翼变形的稳定性和控制优势
Mario Martinez Groves-Raines,Simon Watkins,Abdulghani Mohamed et al.
Mario Martinez Groves-Raines et al.
Birds control flight differently to aircraft, morphing their wings and tail to modify forces rather than relying on hinged control surfaces. Some species, such as kestrels, are more manoeuvrable than similar-sized fixed-wing uncrewed air ve...
Gait transitions in load-pulling quadrupeds: insights from sled dogs and a minimal spring-loaded inverted pendulum model [0.03%]
负载牵引四足动物的步态转换：来自雪橇犬和最小弹簧倒立摆模型的见解

Jiayu Ding et al.
Quadrupedal animals employ diverse galloping strategies to optimize speed, stability and energy efficiency. However, the biomechanical mechanisms that enable adaptive gait transitions during high-speed locomotion under load remain poorly un...
Histology-guided 3D virtual staining of microCT-imaged lung tissue via deep learning [0.03%]
基于深度学习的组织学指导的小鼠肺部微CT图像三维虚拟染色方法研究

Cristina Almagro-Pérez et al.
Histologically stained tissue sections are considered the gold standard for studying microscopic anatomy and diagnosing disease in clinical practice. However, the processes of sectioning and staining are laborious, and the overall method re...
Tuning for feather loss: wing-tail kinematic adjustments of a moulting red-tailed hawk during perching flight [0.03%]
调羽对翅膀和尾巴的影响：红尾

Alfonso Martínez-Carmena
Birds periodically replace feathers through a process known as moult, often resulting in gaps in their wings or tail; however, many birds must retain locomotive capabilities even when moulting, such as perching. Although moult is known to a...

Many congenital conditions and surgical interventions perturb haemodynamics in the proximal pulmonary arteries during postnatal development, thereby altering gene expression and associated changes in vascular structure and function. Among t...
Estimating the in vivo prophylactic effect of mosnodenvir, a novel dengue antiviral, on DENV-2 infection [0.03%]
新型登革病毒抗病毒药物mosnudovir对DENV-2感染的体内预防作用估计
Clare McCormack,Olivia Goethals,Nele Goeyvaerts et al.
Clare McCormack et al.
Almost half of the world's population is at risk of acquiring dengue virus (DENV) each year. However, no specific licensed prophylactic or antiviral treatment for dengue currently exists. Mosnodenvir, a novel DENV inhibitor, has been shown ...
To clean or not to clean: the free-rider problem in sequentially shared resources [0.03%]
打扫还是不打扫：顺序共享资源中的搭便车问题
Alexander Feigel,Alexandre V Morozov
Alexander Feigel
Shared resources enhance productivity, yet at the same time open pathways for biological and digital contamination, turning physical or digital hygiene into a cooperation dilemma prone to free-riding. Here, we introduce a game of sequential...
Alleviating collective action failure through dynamic targets and adaptive punishment in collective-risk dilemmas [0.03%]
在集体风险困境中通过动态目标和适应性惩罚缓解集体行动失败问题
Mingquan Xu,Shijia Hua,Linjie Liu
Mingquan Xu
The question of how to mitigate collective action failure has persistently drawn significant attention from researchers. However, previous theoretical and experimental studies have predominantly assumed a static target, thereby overlooking ...
A quasi-stationary distribution bound for fault analysis in gene regulatory networks [0.03%]
基因调控网络中故障分析的准平稳分布界限
Fabricio Cravo,Matthias Függer,Thomas Nowak
Fabricio Cravo
The inherent stochastic fluctuations in signalling molecules of gene regulatory networks (GRNs) add unpredictability, complicating the design of robust synthetic GRNs that must function within precise ranges. Multi-stable GRNs, such as togg...

Yuan Liu et al.
Cooperation is crucial for both biological and social systems. Yet it is not straightforward from the evolutionary perspective, since individuals are tempted to defect for personal interests. In traditional models, it is usually assumed tha...
