Calculations of the inner mass function Hayward regular black hole with fluxes are reviewed and rederived. We present detailed calculations in two forms Ori approach (the ingoing flux is continuous, outgoing modeled by a thin null shell) compare them Reissner–Nordström hole. A formal reason different results discussed. The energy density scalar perturbations propagating from event horizon into ...

The prefix palindromic length PPLu(n) of an infinite word u is the minimal number concatenated palindromes needed to express n u. Since 2013, it still unknown if unbounded for every aperiodic u, even though this has been proven almost all words. At same time, only well-known nontrivial which function precisely computed Thue-Morse t. This 2-automatic and, predictably, its PPLt(n) 2-regular, but ...

We give lower bounds on the largest singular value of arbitrary matrices, some of which are asymptotically tight for almost all matrices. To study when these bounds are exact, we introduce several combinatorial concepts. In particular, we introduce regular, pseudo-regular, and almost regular matrices. Nonnegative, symmetric, almost regular matrices were studied earlier by Ho¤man, Wolfe, and Ho¤...

BACKGROUND Bronchial asthma is mainly controlled by inhaled corticosteroid (ICS) treatment, and discontinuation of ICS treatment can worsen asthma symptoms and reduce respiratory function. However, the longitudinal impact of ICS on lung function in adult patients is unknown. METHODS To determine whether regular ICS treatment can prevent long-term lung function deterioration in adults with bro...

Previous studies have shown that nicotine can affect beta cell function and insulin secretion in cigarette smokers. The aim of present study was to evaluate the effect of 10 weeks aerobic exercise on insulin and beta cell function in smokers. In this semi-experimental study with pre and post-training design, a total of 36 adult smoker men aged 41±2.5 years were selected into either exerc...

Objective. Uncertainty has arisen as to whether renal function can be recovered from after long-term regular dialysis treatment. We therefore conducted an analysis and scrutinized one patient report. Material and Methods. Swedish registry of patients with kidney disease and one patient case. Results. 39 patients (0.2%) from the Swedish registry comprising 17590 patients who commenced RRT (renal...

The objective of this study was to assess the nutritional adequacy of sub-elite runners with irregular menstrual function (n=10) and that of a comparable group of runners with regular menstrual function (n=10), with a special focus on vitamin E. Based on 3 days' records of weighed dietary intake, the mean energy intakes of micro- and macronutrients were estimated. Both estimated daily energy in...

In this article we study two different generalizations of von Neumann regularity, namely strong topological regularity and weak regularity, in the Banach algebra context. We show that both are hereditary properties and under certain assumptions, weak regularity implies strong topological regularity. Then we consider strong topological regularity of certain concrete algebras. Moreover we obtain ...

A general formulation of the single machine scheduling problem with fuzzy parameters is proposed. Such notions as schedule, cost function and precedence relation are defined. The concept of f regular cost function is introduced and several properties of the class of problems with f -regular cost function are shown.
