Hierarchical patterns, made up of subunits of different sizes intercalated with each other, are present in diverse organisms spanning the plant, fungi and animal kingdoms. Despite these structures appearing in different kingdoms, at differe...

Termites which are able to forage in the open can be often seen, in the field or in the laboratory: (i) wandering around, forming no observable pattern, (ii) clustering themselves in a dense and almost immobile pack, or (iii) milling about ...
Efficient approximations of transcriptional bursting effects on the dynamics of a gene regulatory network [0.03%]

Mathematical models of gene regulatory networks are widely used to study cell fate changes and transcriptional regulation. When designing such models, it is important to accurately account for sources of stochasticity. However, doing so can...
A novel approach to quantify the optimal range and causal effect of rainfall on vector-borne diseases: a case study of dengue epidemics [0.03%]
一种量化降雨量对媒介传染病最优范围和因果影响的新方法——以登革热为例

The quantitative relationship between rainfall and the frequency of dengue outbreaks remains poorly understood, with rainfall's contribution often overlooked or mischaracterized. Taking Guangzhou as the case, we develop a dynamic model to i...

Innovative filtration systems are essential to enhance air quality or improve aerosol sampling for analysis, while addressing challenges such as high energy consumption, clogging and inefficiencies in capturing a wide range of particle diam...
Scaly-tail organ enhances static stability during Pel's scaly-tailed flying squirrels' arboreal locomotion [0.03%]
鳞尾增强了Pel的地栖行动中的静力稳定性鳞尾松鼠的树栖运动

Andrew K Schulz et al.
Scaly-tailed squirrels (Anomaluridae) are one of the least studied mammalian families. Their name is due to a peculiar and unique scaly-tail organ extruding from the caudal vertebra that has been predicted to help reduce skidding. This stud...
Assessment of diagenesis in archaeological human second metacarpal bones using the intensity of the small angle X-ray scattering D-period peak [0.03%]
基于小角X射散强度评估考古人类第二掌骨的成岩作用D峰

Laura Lynne Gardner et al.
Bone consists mainly of carbonated apatite (cAp) nanoplatelets embedded in a matrix of collagen fibrils. Earlier, high-energy small angle X-ray scattering (SAXS) studies of archaeological adult human second metacarpal bones (mc2) found coll...

We reconsider the problem of planetary protection using, by the analogy of planets as islands, the theory of island biogeography. We show that although the notion of equilibrium populations that emerge from the effects of immigration and ex...
Adjoint sensitivity method for parameter estimation: applications to inverted pendulum and human standing balance [0.03%]
伴随敏感性方法在参数估计中的应用：基于倒立摆和人类直立平衡系统模型

Jingtian Chen et al.
The inverted pendulum, a classical mechanical system, often serves as a platform for studying stability and control algorithms. Modelling human standing balance as an inverted pendulum controlled by the time-delayed proportional-derivative ...

While accurate engineered solutions to determine global position require vast networks of well-maintained transponder stations, many animals can solve this problem using only Earth's magnetic field. Moreover, animals are capable of this fea...
