Advanced Science, EarlyView.Zhang et al. identify M7core, a critical cGAS‐STING pathway‐driven gene signature that is activated in most lupus patients’ blood and links to lupus disease severity, lymphopenia, and lupus nephritis. They further reveal the diagnostic and pathogenic characteristics of M7core and emphasize the importance of assessing pathway activity before initiating ...

INTEGRAL REPRESENTATIONS AND INEQUALITIES OF EXTENDED CENTRAL BINOMIAL COEFFICIENTS [PDF]
, 2021 In the paper, the author presents three integral representations of extended central binomial coefficient, proves decreasing and increasing properties of two power-exponential functions involving extended (central) binomial coefficients, derives several double inequalities for bounding extended (central) binomial coefficient, and compares with known ...

Sums of Reciprocals of the Central Binomial Coefficients
, 2006 We consider a set of combinatorial sums involving the reciprocals of the central binomial coefficients and try to solve (or close) them by means of generating functions. We obtain a number of results for infinite sums, in some of which the golden ratio ! appears.

On congruences related to central binomial coefficients
Journal of Number Theory, 2011 It is known that $\sum_{k=0}^\infty\binom{2k}{k}/((2k+1)4^k)= /2$ and $\sum_{k=0}^\infty\binom{2k}{k}/((2k+1)16^k)= /3$. In this paper we obtain their p-adic analogues such as $$\sum_{p/23 is a prime and E_0,E_1,E_2,... are Euler numbers. Besides these, we also deduce some other congruences related to central binomial coefficients.

Relationship Between Knowledge and Compliance With Safety Measures: Evidence From COVID‐19
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Compliance with health safety protocols is important for protecting public health, particularly in agricultural sectors where disease outbreaks can disrupt production and market access. Despite its economic significance, we know little about what drives protocol compliance.

A Note on Extended Binomial Coefficients
, 2014 We study the distribution of the extended binomial coefficients by deriving a complete asymptotic expansion with uniform error terms. We obtain the expansion from a local central limit theorem and we state all coefficients explicitly as sums of Hermite ...

Agribusiness, EarlyView.ABSTRACT The cocoa‐chocolate value chain faces significant environmental and social challenges, driving firms to adopt sustainability strategies ranging from individual practices to third‐party certifications. This study investigates the factors associated with these strategies by analyzing 304 cocoa‐chocolate companies using firm‐level data from the ...

Mixed Parity Variants of Apéry-Type Binomial Series and Level Four Colored Multiple Zeta Values
MathematicsIn this paper, we study an Apéry-type series involving the central binomial coefficients ∑n1>…>nd>014n12n1n1n1−s1…nd−sd and its variations where the summation indices may have mixed parities and some or all “>” are replaced by “≥”, as long as the series ...
