Periodic Solutions of a Singular Equation With Indefinite Weight
Advanced Nonlinear Studies, 2010 AbstractMotivated by some relevant physical applications, we study the existence and uniqueness of T-periodic solutions for a second order differential equation with a piecewise constant singularity which changes sign. Other questions like the stability and robustness of the periodic solution are considered.

Advanced Intelligent Systems, EarlyView.Legged robots have advanced in environmental interaction through contact, but most works rely on fixed contact sequences. This work presents a new method based on an indirect optimization method for legged robots to automatically generate contact sequences for complex movements.

Advanced Intelligent Systems, EarlyView.This work presents compact, low‐voltage actuators based on electropermanent magnetic interactions. The actuators show good overall performance across key metrics and are implemented in wearable devices and untethered robots. Their ability to operate in different configurations and hold positions without energy input highlights their potential for ...

Existence Results for Quasilinear Elliptic Equations with Indefinite Weight [PDF]
Abstract and Applied Analysis, 2012 We provide the existence of a solution for quasilinear elliptic equation in Ω under the Neumann boundary condition. Here, we consider the condition that as t → +∞ and f(x, u) = o(|u|p−1) as |u | → ∞. As a special case, our result implies that the following p‐Laplace equation has at least one solution: −Δpu = λm(x) | u|p−2u + μ | u|r−2u + h(x) in

Positive solutions to indefinite Neumann problems when the weight has positive average
, 2015 We deal with positive solutions for the Neumann boundary value problem associated with the scalar second order ODE $$ u" + q(t)g(u) = 0, \quad t \in [0, T], $$ where $g: [0, +\infty[\, \to \mathbb{R}$ is positive on $\,]0, +\infty[\,$ and $q(t)$ is an ...

Current‐Limiting Control Strategies in Variable Capacitance Electrostatic Energy Harvesters
Advanced Intelligent Systems, EarlyView.This work introduces control strategies for electrostatic energy harvesters that balance energy yield with current limitations. Two approaches are explored: traditional peak‐triggered controls, and newly developed quadrature controls, which use smooth voltage profiles.

How Many Topics? Stability Analysis for Topic Models
, 2014 Topic modeling refers to the task of discovering the underlying thematic structure in a text corpus, where the output is commonly presented as a report of the top terms appearing in each topic. Despite the diversity of topic modeling algorithms that have

2026 Update on the Management of Diffuse Large B‐Cell Lymphoma
American Journal of Hematology, EarlyView.ABSTRACT Diffuse large B‐cell lymphoma (DLBCL) is the most common type of NHL in the Western Hemisphere. It comprises a heterogenous group of lymphomas, with different biology and clinical prognoses. R‐CHP remains the backbone of therapy, and frontline therapeutic options in fit patients are pola‐R‐CHP and R‐CHOP, whereas elderly or frail/unfit ...

Body donor programs in Australia and New Zealand: Current status and future opportunities
Anatomical Sciences Education, Volume 18, Issue 3, Page 301-328, March 2025.Abstract Body donation is critical to anatomy study in Australia and New Zealand. Annually, more than 10,000 students, anatomists, researchers, and clinicians access tissue donated by local consented donors through university‐based body donation programs. However, little research has been published about their operations.
