Class p-wA(s, t) operators and invariant subspaces
, 2020 In this paper we prove that if T ∈ B(H) is a pure class p-wA(s, t) operator (0 < s, t, s + t = 1 and 0 < p ≤ 1) with dense range such that 0 ∈/ σp(T), then T has a non-trivial invariant subspace if and only if its second generalized Aluthge ...

Conditions for a vector subspace E(t) and for a projector P(t) not to depend on t
, 1987 A projector P(t) may depend on t when its range E(t) does not. Conditions for a vector subspace E(t) and for a projector P(t) not to depend on t are established.

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients
Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Geophysical Research LettersInduced earthquakes are occasionally associated with stress oscillations resulting from periodic industrial activities. Yet, the effects of stress oscillations on fault friction under realistic subsurface conditions are not fully clear.

Two-point boundary value problems for 4th order ordinary differential equations
Miskolc Mathematical NotesThe new optimal efficient sufficient conditions are established for solvability and uniqueness of a solution of the linear and nonlinear fourth order ordinary differential equations u^(4)(t) = p(t)u(t) + q(t) for t ∈ [a,b], u^(4)(t) = p(t)u(t) + f(t, u(t)

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Role of Water in the Selection of Stable Proteins at Ambient and Extreme Thermodynamic Conditions
Physical Review X, 2017 Proteins that are functional at ambient conditions do not necessarily work at extreme conditions of temperature T and pressure P. Furthermore, there are limits of T and P above which no protein has a stable functional state.

The role of temperature in P-induced crystal fluid interaction: the case of LAU and HEU topology [PDF]
, 2022 Zeolites are a class of open-framework aluminosilicate minerals commonly present in soil, oceanic basalts and sediments and diagenetic environments. Zeolites may act as fluid carriers in the upper Earth crust during the early subduction stage thanks to ...

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024
Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...

Pargasite at extreme conditions: a comprehensive P-T study
, 2017 Pargasite is a Ca-amphibole associated to medium- or high-pressure/high-temperature conditions. The occurrence of hydroxyl groups into the amphibole’s structure has proved to be a significant agent in the water cycle within the upper mantle (e.g., Gill ...
