Angular analysis of the low $K^{+}K^{-}$ invariant mass enhancement in $B^{+}\to K^{+}K^{-}\pi^{+}$ decays

open access: yes, 2023
We study the decay B+→K+K-π+ and investigate the angular distribution of K+K- pairs with invariant mass below 1.1 GeV/c2. This region exhibits both a strong enhancement in signal and very large direct CP violation.

Sampling Distribution for the K-Th Order Statistics from the Generalized Gumbel Distribution [PDF]

open access: yesThe Egyptian Statistical Journal, 2004
This article is concerned with the sampling distribution of the k-th order statistics of the generalized Gumbel distribution with one shape parameter 2 suggested by Adeyemi (2002). Focusing on the moments for the k-th order statistics numerical solutions

Pharmacokinetics of Two Chlorine-Substituted Bis-Pyridinium Mono-Aldoximes with Regenerating Effect on Butyrylcholinesterase

open access: yesMolecules, 2020
Our aim was to find chlorine-substituted antidotes against organophosphate poisoning and compare their pharmacokinetics to their parent compound, K-203. White male Wistar rats were intramuscularly injected with K-203, K-867 or K-870.

On the value distribution of $ff^{(k)}$ [PDF]

open access: yesKodai Mathematical Journal, 1996
If \(g\) is a transcendental entire function of finite order, then there exists at most one integer \(k\geq 2\), such that \(ff^{(k)}\) has a nonzero and finite Picard exceptional value. If \(f\) is a transcendental meromorphic function, we have that 1) for nonnegative integers \(n,n_1, \dots, n_k\) with \(n\geq 1\), \(d=n_1+ \cdots +n_k\geq 1\), if \(\

Optimal location of logistics distribution centres with swarm intelligent clustering algorithms.

open access: yesPLoS ONE, 2022
A clustering algorithm is a solution for grouping a set of objects and for distribution centre location problems. But the common K-means clustering algorithm may give local optimal solutions. Swarm intelligent algorithms simulate the social behaviours of

Distribution of Semi-k-Free Integers [PDF]

open access: yesProceedings of the American Mathematical Society, 1973
Let Qt(x) denote the number of semi-£-free integers £ix. It is known that Q*(x)=ai*x+0(x1/k), where a* is a constant. In this paper we prove that Aito = fiito - «I* = 0(x1/k cxp{-A lof^xQoglogx)-1^}), where A is an absolute positive constant. Further, on the assump- tion of the Riemann hypothesis, we prove that A*(x) = 0(jc2""+1> exp{/l log x(iog log x)

Distributed k-means algorithm

open access: yesCoRR, 2013
In this paper we provide a fully distributed implementation of the k-means clustering algorithm, intended for wireless sensor networks where each agent is endowed with a possibly high-dimensional observation (e.g., position, humidity, temperature, etc.) The proposed algorithm, by means of one-hop communication, partitions the agents into measure ...
