Factorization of k‐quasihyponormal operators [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1989
Let A be the class of all operators T on a Hilbert space H such that R(T*kT), the range space of T*KT, is contained in R(T*k+1), for a positive integer k. It has been shown that if T ϵ A, there exists a unique operator CT on H such that urn:x-wiley:01611712:media:ijmm367931:ijmm367931-math-0001 The main objective of this paper is to characterize k ...

Form factor in K+ --> pi+ pi0 gamma: interference versus direct emission [PDF]

open access: yes, 2007
We analyze the effect of a form factor in the magnetic contribution to K+ --> pi+ pi0 gamma. We emphasize how this can show up experimentally: in particular we try to explore the difference between a possible interference contribution and a form factor ...

The k-mismatch problem revisited [PDF]

open access: yes, 2015
We revisit the complexity of one of the most basic problems in pattern matching. In the k-mismatch problem we must compute the Hamming distance between a pattern of length m and every m-length substring of a text of length n, as long as that Hamming ...

Determination of the CP Violating Phase $\gamma$ by a Sum Over Common Decay Modes to $B_s$ and $\bar{B}_s$

open access: yes, 1994
To help the difficult determination of the angle $\gamma$ of the unitarity triangle, Aleksan, Dunietz and Kayser have proposed the modes of the type $K^-D^+_s$, common to $B_s$ and $\bar{B}_s$.

Multiple Coagulation Factor Deficiency: A Series of Eight Cases [PDF]

open access: yesJournal of Clinical and Diagnostic Research
Multiple Coagulation Factor Deficiency (MCFD) is an uncommon haematological disorder characterised by simultaneous deficiency of multiple clotting factors, which leads to an increased risk of bleeding and compromised haemostasis. The present series aimed

A Quality Improvement Initiative to Standardize Pneumocystis jirovecii Pneumonia Prophylaxis in Pediatric Patients With Solid Tumors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about

A $[k,k+1]$-Factor Containing A Given Hamiltonian Cycle [PDF]

open access: yesThe Electronic Journal of Combinatorics, 1998
We prove the following best possible result. Let $k\ge 2$ be an integer and $G$ be a graph of order $n$ with minimum degree at least $k$. Assume $n \ge 8k-16$ for even $n$ and $n \ge 6k-13$ for odd $n$. If the degree sum of each pair of nonadjacent vertices of $G$ is at least $n$, then for any given Hamiltonian cycle $C$ of $G$, $G$ has a $[k,\,k+1 ...

Identification of 331 quantum Hall states with Mach-Zehnder interferometry

open access: yes, 2010
It has been shown recently that non-Abelian states and the spin-polarized and unpolarized versions of the Abelian 331 state may have identical signatures in Fabry-P\'{e}rot interferometry in the quantum Hall effect at filling factor 5/2. We calculate the

Vertex Sparsifiers: New Results from Old Techniques [PDF]

open access: yes, 2014
Given a capacitated graph $G = (V,E)$ and a set of terminals $K \subseteq V$, how should we produce a graph $H$ only on the terminals $K$ so that every (multicommodity) flow between the terminals in $G$ could be supported in $H$ with low congestion, and ...
