Journal of Numerical Analysis and Approximation Theory, 2010 In this paper, we obtain new results concerning the generalizations of additive and multiplicative majorizations by means of exponential convexity. We prove positive semi-definiteness of matrices generated by differences deduced from majorization type ...

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.

On positive definite hermitian forms
manuscripta mathematica, 1991 This work has originated from a question posed by Serre, in connection with his study of the maximal number of rational points on curves of genus 3 over finite fields, to Kneser io 1983. Over which orders in imaginary quadratic fields does an indecomposable positive definite unimodular Hermitian form of rank 3 exist? The corresponding question for rank

Planning and Control Framework for a Quadruped Robot With Changeable Configuration
Advanced Intelligent Systems, EarlyView.Multiconfiguration quadruped robots enhance adaptability by switching between mammal‐like and reptile‐like morphologies. This study presents a nonlinear constraint‐based motion planner integrated with a hierarchical whole‐body controller, enabling robust configuration switching and locomotion on complex terrains. Experiments on slopes, irregular bricks,

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.ABSTRACT Ernst Rüdin, an important and controversial figure in the history of psychiatric genetics, published only one major empirical study on siblings of dementia praecox (DP) probands in 1916. He conducted a parallel study of siblings of probands with manic‐depressive insanity (MDI), but the resulting monograph, written in the early 1920s, was left ...

Intact Proteoform Analysis by Capillary Electrophoresis–Mass Spectrometry. Are We There Yet?
Angewandte Chemie, EarlyView.Mass spectrometry (MS) and top–down proteomics (TDP) have emerged as powerful tools to decipher proteoform‐level information, advancing biological insight and translational research. This study unites leaders in capillary electrophoresis (CE) and MS from multiple institutions across the globe to showcase the reproducibility, unique information, and ...

‘Turkeys Cannot Vote for Christmas’: Why Epistemic Disobedience in an Anti‐Black World Matters
Australian Journal of Social Issues, EarlyView.ABSTRACT Never in the history of global coloniality has the idea of epistemic disobedience been as important as in the 21st century. This is not only because the struggle for decolonisation has shifted from physical confrontation between the coloniser and the colonised into a battle of ideas but also because the former has deployed the idea of ...

Persisting Transglutaminase 6 Antibodies in Neurological Gluten‐Related Disorders
Annals of Neurology, EarlyView.Objective Gluten‐related autoimmunity can cause neurological disease, although the best way to diagnose and monitor such patients is unclear. Serological testing for antibodies against transglutaminase 6 (TG6) has been proposed; however, this is not widely available in clinical practice.
