Nonreciprocal Swarmalators With Reconfigurable and Controllable Formations for Robot Collectives
Advanced Robotics Research, EarlyView.Nonreciprocal swarmalator interactions are enabled through control barrier functions to transform self‐organizing robot collectives into reconfigurable, constraint‐aware systems. Complex two‐ and three‐dimensional shapes, continuous morphing, obstacle‐aware navigation, collective splitting, and object transport emerge from modulating agent‐level ...

A Riccati technique for proving oscillation of a half-linear equation
Electronic Journal of Differential Equations, 2008 In this paper we study the oscillation of solutions to the half-linear differential equation $$ (r(t)|y'|^{p-1}hbox{sgn} y)'+c(t)|y|^{p-1}hbox{sgn} y=0, $$ under the assumptions $int^infty r^{1/(1-p)}(s),ds0$, $p>1$.

Oscillation Criteria for Odd Order Neutral Equations
Journal of Mathematical Analysis and Applications, 1994 Some results are obtained for oscillation of all solutions of the odd order neutral differential equation \[ (x(t)- px(t- \tau))^{(n)}+ \sum^ m_{i= 1} p_ i(t) f_ i(x(t- \sigma_ i))= 0,\tag{1} \] where \(p_ i(t)\geq 0\), \(\sigma_ i\in (0, \infty)\), \(f_ i: \mathbb{R}\to \mathbb{R}\) \((i= 1,2,\dots, m)\), \(p, \tau\in [0, \infty)\).

Advanced Robotics Research, EarlyView.A sea turtle‐inspired amphibious robot uses simulation‐guided optimization to adapt its flipper coordination to different environments. Sensitivity analysis and multiobjective Bayesian optimization identify terrain‐dependent controllers that are validated on hardware.

Oscillation criteria for nth-order forced functional differential equations
, 2003 In this paper, by using the method of general means, some new oscillation criteria for forced functional differential equations of the form x(n)(t)+∑i=1n−1aix(i)(t)+q(t)fxg(t)=e(t),t0⩾0, are established, where ai are real constants, q(t), f(t), e(t), and

A Critical Time Window of Neocortex Modulation for Remote Fear Memory in Rats and Humans
Advanced Science, EarlyView.This study identifies a delayed consolidation window around 18 h after fear learning in the mPFC essential for remote fear memory. VTA dopaminergic input during this window sustains remote memory in rats, while non‐invasive stimulation of homologous human mPFC at the corresponding time selectively weakens remote but not recent fear memory, revealing a ...
