In this note we consider the question under which conditions all entries of the matrix I-(I+X)-1 are nonnegative in case matrix X is a real positive definite matrix.Sufficient conditions are presented as well as some necessary conditions.One sufficient ...

Computing Generalized Inverse Systems using Matrix Pencil Methods [PDF]
, 2001 We address the numerically reliable computation of generalized inverses of rational matrices in descriptor state-space representation. We put particular emphasis on two classes of inverses: the weak generalized inverse and the Moore-Penrose pseudoinverse.

Journal of Product Innovation Management, EarlyView.ABSTRACT Responsible innovation (RI) dynamics remain underexplored in Global South contexts, which have a high prevalence of micro‐ and small enterprises and are vulnerable to the devastating effects of industrial disasters. Only a few studies examine RI within such settings, where it is arguably needed most.

, 1978 An algorithm that uses integer arithmetic is suggested. It transforms anm ×n matrix to a diagonal form (of the structure of Smith Normal Form). Then it computes a reflexive generalized inverse of the matrix exactly and hence solves a system of linear ...

Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary Boosting slow‐wave activity (SWA) by modulating slow waves through closed‐loop auditory stimulation (CLAS) might provide a powerful non‐pharmacological tool to investigate the link between sleep and neurodegeneration. Here, we established mouse CLAS (mCLAS)‐mediated SWA enhancement and explored its effects on sleep deficits in neurodegeneration,

Easing the Burden? Religiosity and Educational Inequality in Pain Interference
Journal for the Scientific Study of Religion, EarlyView.ABSTRACT A consistent inverse gradient in pain prevalence is typically observed across educational strata. Religion stands out as a source of social and personal support that may moderate the amount of chronic pain interference but may do so differently across the educational spectrum.

Journal of Time Series Analysis, EarlyView.ABSTRACT The paper deals with the construction of a synthetic indicator of economic growth, obtained by projecting a quarterly measure of aggregate economic activity, namely gross domestic product (GDP), into the space spanned by a finite number of smooth principal components, representative of the medium‐to‐long‐run component of economic growth of a ...

Experimental Physiology, EarlyView.Abstract Epilepsy is characterized by the occurrence of at least two unprovoked seizures occurring more than 24 h apart, reflecting a predisposition to recurrent epileptic events. The role of dietary amino acids (AAs) in epilepsy is not clearly understood. To the best of our knowledge, this study is the first to investigate the link between the odds of

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes
The Journal of Physiology, EarlyView.Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Model predictive control architecture for rotorcraft inverse simulation [PDF]
, 2013 A novel inverse simulation scheme is proposed for applications to rotorcraft dynamic models. The algorithm adopts an architecture that closely resembles that of a model predictive control scheme, where the controlled plant is represented by a high-order ...
