We introduce the notion of decoupling for operators, and prove an equivalence between classical $\ell^qL^p$ decoupling for functions and $\ell^q\mathcal{S}^p$ decoupling for operators on bounded sets in $\mathbb{R}^{2d}$. We also show that the equiva

We formulate a variant of Fourier restriction for operators in Schatten classes, where the Fourier-Wigner transform of a bounded operator replaces the Fourier transform of a function. The Fourier-Wigner transform is closely related to the group Fouri

Abstract Background In 2016, Burkina Faso adopted a new community-based model for disease surveillance, appointing two community-based health workers (CBHWs) per village. The CBHWs play a crucial yet under-researched role in Burkina Faso’s health s

In this paper we prove a uniform Fourier restriction estimate over the class of simple curves where the last coordinate function can be extended to a holomorphic function of bounded frequency in a sufficiently large disc. The proof is based on a deco

IntroductionImmunoparalysis is a state of immune dysfunction characterized by a marked reduction in the immune system’s responsiveness, often observed following severe infections, trauma, or critical illness. This study aimed to perform a longitudi

Four specimens of Balistes carolinensis (Balistidae, Plectognathi) were taken in Norwegian waters in autumn 1995. The first was taken 21 August in the Norwegian Sea SW of Perjohanneset (63°11' N, 04°45' E), while the three others were caught on the

Abstract The tobacco alkaloid nicotine is known for its activation of neuronal nicotinic acetylcholine receptors. Nicotine is consumed in different ways such as through conventional smoking, e-cigarettes, snuff or nicotine pouches. The use of snuff h

Abstract Multi-drug resistant (MDR) E. coli constitute a major public health burden globally, reaching the highest prevalence in the global south yet frequently flowing with travellers to other regions. However, our comprehension of the entire geneti

OBJECTIVES:. While cytokine response patterns are pivotal in mediating immune responses, they are also often dysregulated in sepsis and critical illness. We hypothesized that these immunological deficits, quantifiable through ex vivo whole blood stim

A simple model for viscous liquid dynamics is introduced. Consider the surface of the union of hyper-spheres centered at random positions inside a hypercube with periodic boundary conditions. It is argued and demonstrated by numerical simulations tha
