Factorization of leading chiral logarithms in the pion form factors [PDF]

open access: yes, 2013
In the recently proposed framework of hard pion chiral perturbation theory, the leading chiral logarithms are predicted to factorize with respect to the energy dependence in the chiral limit.

On repdigits as product of $k$-Fibonacci and $k$-Lucas numbers [PDF]

open access: yesMathematica Bohemica
For an integer $k\geq2$, let $(F_n^{(k)})_{n\geq-(k-2)}$, $(L_n^{(k)})_{n \geq-(k-2)}$ be $k$-Fibonacci and $k$-Lucas sequences, respectively. For these sequences the first $k$ terms are $0,\ldots,0,1$ and $0,\ldots,0,2,1$, respectively, and each term ...

On $k$-Pell numbers which are sum of two Narayana's cows numbers [PDF]

open access: yesMathematica Bohemica
For any positive integer $k\geq2$, let $(P_n^{(k)})_{n\geq2-k}$ be the $k$-generalized Pell sequence which starts with $0,\cdots,0,1$ ($k$ terms) with the linear recurrence P_n^{(k)} = 2P_{n-1}^{(k)}+P_{n-2}^{(k)}+\cdots+P_{n-k}^{(k)}\quad\text{for} n\

On Terms of Generalized Fibonacci Sequences which are Powers of their Indexes

open access: yesMathematics, 2019
The k-generalized Fibonacci sequence ( F n ( k ) ) n (sometimes also called k-bonacci or k-step Fibonacci sequence), with k ≥ 2 , is defined by the values 0 , 0 , … , 0 , 1 of starting k its terms and such way ...

Scaling, normalizing, and per ratio standards: an allometric modeling approach. [PDF]

open access: yes, 1995
The practice of scaling or normalizing physiological variables (Y) by dividing the variable by an appropriate body size variable (X) to produce what is known as a "per ratio standard" (Y/ X), has come under strong criticism from various authors.

An Electrochemical Sensor Based on Allosteric Molecular Beacons for DNA Detection of Escherichia Coli. O157:H7

open access: yesInternational Journal of Electrochemical Science, 2013
In this work, an E-sensor basing on allosteric molecular beacons (aMBs) was designed for detection of Escherichia coli.(E. coli.)O157:H7 DNA. Without the target DNA, the aMB formed a stable hairpin structure which blocked the binding capability of the ...

Solving elliptic Diophantine equations by estimating linear forms in elliptic logarithms [PDF]

open access: yes, 1994
In order to compute all integer points on a Weierstraß equation for an elliptic curve E/Q, one may translate the linear relation between rational points on E into a linear form of elliptic logarithms.

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...

Biphasic Clinical Course of Pediatric Cytomegalovirus‐Associated Immune Thrombocytopenia: Early Poor Treatment Response but Favorable Long‐Term Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cytomegalovirus (CMV) is a recognized trigger of immune thrombocytopenia (ITP); however, its incidence and impact on disease course in children remain controversial. Therefore, we aimed to characterize the clinical course of pediatric patients with CMV‐associated ITP.

Fibonacci and Lucas numbers of the form -2^a-3^b-5^c+7^d

open access: yesRevista Integración
In this note we find all Fibonacci and Lucas numbers of the form -2^a-3^b-5^c+7^d where a, b, c, d are non-negative integers, with 0 ≤ max{a, b, c} ≤ d. This result gives an answer to a question posed by Qu, Zeng and Cao.
