Faster Asynchronous Nonconvex Block Coordinate Descent with Locally Chosen Stepsizes
Matthew Ubl, Matthew Hale
Distributed nonconvex optimization problems underlie many applications in learning and autonomy, and such problems commonly face asynchrony in agents' computations and communications. When delays in these operations are bounded, they are called partially asynchronous. In this paper, we present an uncoordinated stepsize…

Disturbance-resilient Distributed Resource Allocation over Stochastic Networks using Uncoordinated Stepsizes
Tie Ding, Shanying Zhu, Cailian Chen, Xinping Guan
—This paper studies distributed resource allocation problem in multi-agent systems, where all the agents cooperatively minimize the sum of their cost functions with global resource constraints over stochastic communication networks. This problem arises from many practical domains such as economic dispatch in smart…

Decentralized Gradient Methods with Time-varying Uncoordinated Stepsizes: Convergence Analysis and Privacy Design
Yongqiang Wang, Angelia Nedić
—Decentralized optimization enables a network of agents to cooperatively optimize an overall objective function without a central coordinator and is gaining increased attention in domains as diverse as control, sensor networks, data mining, and robotics. However, the information sharing among agents in decentralized…

Decentralized Primal-Dual Proximal Operator Algorithm for Constrained Nonsmooth Composite Optimization Problems over Networks
Liping Feng, Liang Ran, Guoyang Meng, Jialong Tang + 3 more
'Huaqing Li' 'Shu-Chuan Chu'] In this paper, we focus on the nonsmooth composite optimization problems over networks, which consist of a smooth term and a nonsmooth term. Both equality constraints and box constraints for the decision variables are also considered. Based on the multi-agent networks, the objective…

Insects Use Two Distinct Classes of Steps during Unrestrained Locomotion Two Classes of Steps in Insect Locomotion
Leslie M. Theunissen, Volker Dürr, Holger G Krapp
Background Adaptive, context-dependent control of locomotion requires modulation of centrally generated rhythmic motor patterns through peripheral control loops and postural reflexes. Thus assuming that the modulation of rhythmic motor patterns accounts for much of the behavioural variability observed in legged…

Mechanical Characterization of One-Headed Myosin-V Using Optical Tweezers Steps of One-Headed Myosin-V
Tomonobu M. Watanabe, Atsuko H. Iwane, Hiroto Tanaka, Mitsuo Ikebe + 2 more
Class V myosin (myosin-V) is a cargo transporter that moves along an actin filament with large (∼36-nm) successive steps. It consists of two heads that each includes a motor domain and a long (23 nm) neck domain. One of the more popular models describing these steps, the hand-over-hand model, assumes the two-headed…

Multisensory cues facilitate coordination of stepping movements with a virtual reality avatar
Omar Khan, Imran Ahmed, Joshua Cottingham, Musa Rahhal + 2 more
'Theodoros N. Arvanitis' 'Mark Elliott'] The effectiveness of simple sensory cues for retraining gait have been demonstrated, yet the feasibility of humanoid avatars for entrainment have yet to be investigated. Here, we describe the development of a novel method of visually cued training, in the form of a virtual…

Auxin-inducible degradation of UNC-116 in *C. elegans* inhibits bidirectional dense core vesicle transport and worm locomotion on different timescales
Astrid Boström, Anna Gavrilova, Gino B. Poulin, Victoria J. Allan
The microtubule motor kinesin-1 is vital in neurons, with mutations being associated with neurological diseases. Deletion of the Caenorhabditis elegans kinesin-1 gene unc-116 is lethal, and viable mutants are uncoordinated. Here, we use auxin-mediated degradation to deplete UNC-116 protein at different developmental…

New generalized variable stepsizes of the CQ algorithm for solving the split feasibility problem
Peiyuan Wang, Jianjun Zhou, Risheng Wang, Jie Chen
Variable stepsize methods are effective for various modified CQ algorithms to solve the split feasibility problem (SFP). The purpose of this paper is first to introduce two new simpler variable stepsizes of the CQ algorithm. Then two new generalized variable stepsizes which can cover the former ones are also proposed…

Genetic dissection of a *Leishmania* flagellar proteome demonstrates requirement for directional motility in sand fly infections
Tom Beneke, François Demay, Edward Hookway, Nicole Ashman + 11 more
The protozoan parasite Leishmania possesses a single flagellum, which is remodelled during the parasite’s life cycle from a long motile flagellum in promastigote forms in the sand fly to a short immotile flagellum in amastigotes residing in mammalian phagocytes. This study examined the protein composition and in vivo…

Robust spatial self-organization in crowds of asynchronous pedestrians
Takenori Tomaru, Yuta Nishiyama, Claudio Feliciani, Hisashi Murakami
Similar to other animal groups, human crowds exhibit a variety of self-organized collective behaviors. Spontaneous formation of unidirectional lanes in bidirectional pedestrian flows is one of the most striking examples of self-organization in human crowds. In addition, previous experimental studies have suggested that…

Cerebellar activity is triggered by reach endpoint during learning of a complex locomotor task
Andry Andrianarivelo, Heike Stein, Jeremy Gabillet, Clarisse Batifol + 3 more
Locomotion in complex environments depends on the precise timing and active control of single paw movements in order to adapt steps to surface structure and coordinate paws. Such motor control crucially depends on the cerebellum, which is thought to support moment-to-moment prediction and correction of paw…
