Spherical Tuples of Hilbert Space Operators [PDF]
, 2014 We introduce and study a class of operator tuples in complex Hilbert spaces, which we call spherical tuples. In particular, we characterize spherical multi-shifts, and more generally, multiplication tuples on RKHS.

Redrawing the Mannich‐Type Reaction through Carbonyl Umpolung Reactivity
Advanced Synthesis &Catalysis, EarlyView.GA: Herein, a conceptually novel one‐pot multicomponent strategy is reported for the streamlined construction of five‐membered imidazolidines from 1,2‐diaza‐1,3‐dienes (onefold), amines (twofold), and formaldehyde (twofold). This redesigned Mannich‐type reaction that exploits a carbene‐like activity of 1,2‐diaza‐1,3‐dienes (realized by “umpolung ...

Demonstratio MathematicaWe study the boundedness of commutators of the Hardy-Littlewood maximal function and the sharp maximal function on weighted Morrey spaces when the symbols of the commutators belong to weighted Lipschitz spaces (weighted Morrey-Campanato spaces). Some new

Writing commutators of commutators as products of cubes [PDF]
Communications in Algebra, 2021 It is known that commutators of commutators can be written as products of cubes, with the current upper bound on the number of cubes being 60. We discuss how proofs extracted via coset enumeration can be used to investigate this problem, and exhibit a rewriting using only 14 cubes.

Advanced Science, EarlyView.CellPhenoX is an explainable machine learning framework that identifies cell‐specific phenotypes and interaction effects from single‐cell omics data. By leveraging interpretable models, it enables robust discovery of cell‐level phenotypes that contribute to clinical outcomes.

Advanced Science, EarlyView.Repeated neonatal sevoflurane exposure impairs adolescent fear memory through Igfbp2 downregulation in paraventricular thalamus‐central amygdala glutamatergic projections. Restoring Igfbp2 or activating this circuit rescues memory deficits, neuronal excitability, and spine density, identifying a precise molecular target for preventing anesthesia ...

, 2008 The main result is that the commutators on $\ell_1$ are the operators not of the form $\lambda I + K$ with $\lambda\neq 0$ and $K$ compact. We generalize Apostol's technique (1972, Rev. Roum. Math. Appl.

Targeting Histamine H4 Receptor in the Rostral Ventromedial Medulla to Relieve Hypertension
Advanced Science, EarlyView.H4R and its downstream TRPV1 channel mediate the excitatory effect of TMN histaminergic afferent inputs on GABAergic sympathoinhibitory neurons in RVMM. Intranasal delivery of selective H4R agonist VUF 8430 suppresses renal sympathetic outflow and elicits sustained depressor and bradycardia responses in SHRs and CUMS‐induced hypertensive rats ...

Information and Computation, 1987 A semi-commutation system \(S=\) is a semi-Thue system, where X is a finite alphabet and P is a set of production rules of the form xy\(\to yx\) for some x,y\(\in X\), \(x\neq y\). The corresponding semi-commutation is the map which assigns to every set \(R\subseteq X^*\) of words over X the set f(R) of all words over X which can be derived from some ...
