On an isolation and a generalization of Hölder's inequality

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We generalize the well-known Hölder inequality and give a condition at which the equality holds.

The Role of Certifications in Improving Household Food Security Among Peruvian Farmers

open access: yesAgribusiness, EarlyView.
ABSTRACT Achieving global food security requires sustainable transformations in agri‐food systems. Voluntary Sustainability Standards (VSS) such as Organic and Fairtrade aim to internalize certain social and environmental costs while promoting more equitable value distribution, improved market access, and sustainable production practices.

Some inequalities involving the extended gamma function and the Kummer confluent hypergeometric k-function

open access: yesJournal of Inequalities and Applications, 2018
In the paper, the authors present some inequalities involving the extended gamma function and the Kummer confluent hypergeometric k-function via some classical inequalities such as Chebychev’s inequality for synchronous (or asynchronous, respectively ...

Trends in Gender Disparities in Surgical Experience: A National Clinical Database Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background We previously reported the gender disparities in surgical procedures between male and female surgeons using National Clinical Database covering more than 95% of all operations performed in Japan. This study aims to examine the changes in gender disparity in the surgical experience of gastrointestinal surgeons in Japan before and ...

In Situ Graph Reasoning and Knowledge Expansion Using Graph‐PRefLexOR

open access: yesAdvanced Intelligent Discovery, EarlyView.
Graph‐PRefLexOR is a novel framework that enhances language models with in situ graph reasoning, symbolic abstraction, and recursive refinement. By integrating graph‐based representations into generative tasks, the approach enables interpretable, multistep reasoning.

Real‐Time Control of a Humanoid Robot for Whole‐Body Tactile Interaction

open access: yesAdvanced Intelligent Systems, EarlyView.
Inspired by human tactile interaction, this work integrates large‐area artificial skin feedback (force and proximity) into real‐time quadratic programming control for humanoids. This enables robots to leverage distributed sensing to manage forces, safely move around unknown and dynamic obstacles, and robustly handle objects with uncertain geometry ...

Homogenization of a parabolic Dirichlet problem by a method of Dahlberg

open access: yes, 2016
Consider the linear parabolic operator in divergence form $$\mathcal{H} u =\partial_t u(X,t)-\text{div}(A(X)\nabla u(X,t)).$$ We employ a method of Dahlberg to show that the Dirichlet problem for $\mathcal{H}$ in the upper half plane is well-posed for ...

Enhancing Microrobot Swarm Stability and Adaptation by Autonomous Field‐of‐View Planning

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents an adaptive cross‐field‐of‐view navigation strategy for microrobot swarms in large‐scale workspaces by integrating global path planning via A* and local replanning using optimized informed rapidly‐exploring random tree star . The hybrid approach ensures efficient and robust trajectory execution in dynamic environments, enhancing the ...
