, 2017 We consider the set Bp of parametric block correlation matrices with p blocks of various (and possibly different) sizes, whose diagonal blocks are compound symmetry (CS) correlation matrices and off-diagonal blocks are constant matrices.

Elastic Fast Marching Learning from Demonstration
Advanced Intelligent Systems, EarlyView.This article presents Elastic Fast Marching Learning (EFML), a novel approach for learning from demonstration that combines velocity‐based planning with elastic optimization. EFML enables smooth, precise, and adaptable robot trajectories in both position and orientation spaces.

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,

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 ...

Pure Red Cell Aplasia Associated With Thymic Tumors, a Nationwide Retrospective Study
American Journal of Hematology, EarlyView.ABSTRACT Pure red cell aplasia (PRCA) is the most frequent autoimmune cytopenia associated with thymic tumors (TTs). In a nationwide retrospective study, we included 41 patients (22 women, median age 62 years). At PRCA diagnosis, the mean hemoglobin level was 6.6 ± 2.1 g/dL, and the reticulocyte count was 6 ± 5 × 109/L. PRCA was diagnosed before TT (8%,

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 ...

Asian Journal of Organic Chemistry, EarlyView.Quantum–chemical calculations were carried out to rationalize the Lewis acid structure dependence on the catalytic activity in the intramolecular Hosomi–Sakurai reaction of o–allylsilyl benzaldehyde to generate benzoxasilole. Abstract The reaction mechanism of the Lewis acid–catalyzed intramolecular Hosomi–Sakurai reaction of o–allylsilyl benzaldehyde ...
