Simulating the effect of ankle plantarflexion and inversion-eversion exoskeleton torques on center of mass kinematics during walking

Plos.org 

by Nicholas A. Bianco, Steven H. Collins, Karen Liu, Scott L. Delp

Walking balance is central to independent mobility, and falls due to loss of balance are a leading cause of death for people 65 years of age and older. Bipedal gait is typically unstable, but healthy humans use corrective torques to counteract perturbations and stabilize gait. Exoskeleton assistance could benefit people with neuromuscular deficits by providing stabilizing torques at lower-limb joints to replace lost muscle strength and sensorimotor control.

Geometry of population activity in spiking networks with low-rank structure

Plos.org 

by Ljubica Cimeša, Lazar Ciric, Srdjan Ostojic

Recurrent network models are instrumental in investigating how behaviorally-relevant computations emerge from collective neural dynamics. A recently developed class of models based on low-rank connectivity provides an analytically tractable framework for understanding of how connectivity structure determines the geometry of low-dimensional dynamics and the ensuing computations. Such models however lack some fundamental biological constraints... Читать дальше...

Evolutionary dynamics on sequential temporal networks

Plos.org 

by Anzhi Sheng, Aming Li, Long Wang

Population structure is a well-known catalyst for the evolution of cooperation and has traditionally been considered to be static in the course of evolution. Conversely, real-world populations, such as microbiome communities and online social networks, frequently show a progression from tiny, active groups to huge, stable communities, which is insufficient to be captured by constant structures. Here, we propose sequential temporal networks to characterize growing networked populations... Читать дальше...

Ensemble inference of unobserved infections in networks using partial observations

Plos.org 

by Renquan Zhang, Jilei Tai, Sen Pei

Undetected infections fuel the dissemination of many infectious agents. However, identification of unobserved infectious individuals remains challenging due to limited observations of infections and imperfect knowledge of key transmission parameters. Here, we use an ensemble Bayesian inference method to infer unobserved infections using partial observations. The ensemble inference method can represent uncertainty in model parameters and update model states using all ensemble members collectively. Читать дальше...

Synaptic weights that correlate with presynaptic selectivity increase decoding performance

Plos.org 

by Júlia V. Gallinaro, Benjamin Scholl, Claudia Clopath

The activity of neurons in the visual cortex is often characterized by tuning curves, which are thought to be shaped by Hebbian plasticity during development and sensory experience. This leads to the prediction that neural circuits should be organized such that neurons with similar functional preference are connected with stronger weights. In support of this idea, previous experimental and theoretical work have provided evidence for... Читать дальше...

Patagonian Shadow Pavilion / DRAA

Archdaily.com 

A particular cultural mix has provided a series of unexpected suspended objects to the Patagonian landscape. Structures that are seemingly useless or at best oversized with a single cover become landmarks, indicating ownership or marking the way.

You’re Watching Football Wrong, According to NFL Star Travis Kelce

Adweek.com 

NFL star Travis Kelce is throwing a penalty flag on your TV setup. In a new campaign extension for DirecTV's brand strategy platform "TV Without Compromise," the Kansas City Chiefs tight end and Super Bowl winner gets overly direct, telling viewers they're watching football all wrong. Through a series of spots, Kelce roasts fans for...

Barcelona pulls in big crowds across the USA

World Soccer Talk: World Cup 2014 

Spanish giants FC Barcelona returned to America this summer, taking part in the Soccer Champions Tour as a headlining participant. And as usual, the legendary Catalan club was very effective at getting fans through the gates. FC Barcelona pulled some of the largest crowds for soccer in the USA to date in 2023. Originally the […]
