Jacobson’s conjecture and skew PBW extensions [PDF]

Revista Integración, 2014
The aim of this paper is to compute the Jacobson’s radical of skew PBW extensions over domains. As a consequence of this result we obtain a direct relation between these extensions and the Jacobson’s conjecture, which implies that skew PBW extensions ...

Pointed Hopf algebras over nonabelian groups with nonsimple standard braidings

Proceedings of the London Mathematical Society, Volume 127, Issue 4, Page 1185-1245, October 2023., 2023
Abstract We construct finite‐dimensional Hopf algebras whose coradical is the group algebra of a central extension of an abelian group. They fall into families associated to a semisimple Lie algebra together with a Dynkin diagram automorphism. We show conversely that every finite‐dimensional pointed Hopf algebra over a nonabelian group with nonsimple ...

Construction of a web‐based dynamic nomogram for predicting the prognosis in acute heart failure

ESC Heart Failure, Volume 10, Issue 4, Page 2248-2261, August 2023., 2023
Abstract Aims The early identification and appropriate management may provide clinically meaningful and substained benefits in patients with acute heart failure (AHF). This study aimed to develop an integrative nomogram with myocardial perfusion imaging (MPI) for predicting the risk of all‐cause mortality in AHF patients.

Gaudin algebras, RSK and Calogero–Moser cells in Type A

Proceedings of the London Mathematical Society, Volume 126, Issue 5, Page 1467-1495, May 2023., 2023
Abstract We study the spectrum of a family of algebras, the inhomogeneous Gaudin algebras, acting on the n$n$‐fold tensor representation C[x1,…,xr]⊗n${\mathbb{C}}[x_1, \ldots , x_r]^{\otimes n}$ of the Lie algebra glr$\mathfrak {gl}_r$. We use the work of Halacheva–Kamnitzer–Rybnikov–Weekes to demonstrate that the Robinson–Schensted–Knuth ...

Within‐day bidirectional associations between physical activity and affect: A real‐time ambulatory study in persons with and without depressive and anxiety disorders

Depression and Anxiety, Volume 39, Issue 12, Page 922-931, December 2022., 2022
Abstract Background Ambulatory assessments offer opportunities to study physical activity level (PAL) and affect at the group and person‐level. We examined bidirectional associations between PAL and affect in a 3‐h timeframe and evaluated whether associations differ between people with and without current or remitted depression/anxiety.

A review of fault diagnosis, prognosis and health management for aircraft electromechanical actuators

IET Electric Power Applications, Volume 16, Issue 11, Page 1249-1272, November 2022., 2022
Abstract As More/All Electric Aircraft gradually become a research hotspot, electromechanical actuators (EMAs), which can directly convert electrical energy into mechanical energy, have gained more and more attention. However, since the reliability of EMA cannot meet the requirements of actual aircrafts, the practical application of EMA is severely ...

Responses of floodplain birds to high‐amplitude precipitation fluctuations over two decades

Austral Ecology, Volume 47, Issue 4, Page 828-840, June 2022., 2022
Abstract Globally, high‐amplitude variation in weather (e.g. precipitation) is increasing in frequency and magnitude. This appears to be so for the southern Murray‐Darling Basin, Australia, where droughts of unprecedented (in the instrumental record, extending back to the mid‐1800s) depth and duration (1997–first half of 2010; second half of 2012–) are

Psychosocial factors and cancer incidence (PSY‐CA): Protocol for individual participant data meta‐analyses

Brain and Behavior, Volume 11, Issue 10, October 2021., 2021
Abstract Objectives Psychosocial factors have been hypothesized to increase the risk of cancer. This study aims (1) to test whether psychosocial factors (depression, anxiety, recent loss events, subjective social support, relationship status, general distress, and neuroticism) are associated with the incidence of any cancer (any, breast, lung, prostate,

Quantum Grothendieck rings as quantum cluster algebras

Journal of the London Mathematical Society, Volume 103, Issue 1, Page 161-197, January 2021., 2021
Abstract We define and construct a quantum Grothendieck ring for a certain monoidal subcategory of the category O of representations of the quantum loop algebra introduced by Hernandez–Jimbo. We use the cluster algebra structure of the Grothendieck ring of this category to define the quantum Grothendieck ring as a quantum cluster algebra.

Relationship between Driving Pressure and Mortality in Ventilated Patients with Heart Failure: A Cohort Study

Canadian Respiratory Journal, Volume 2021, Issue 1, 2021., 2021
Background. Heart failure (HF) is a leading cause of mortality and morbidity worldwide, with an increasing incidence. Invasive ventilation is considered to be essential for patients with HF. Previous studies have shown that driving pressure is associated with mortality in acute respiratory distress syndrome (ARDS).
