A Fast Algorithm for Computing Binomial Coefficients Modulo Powers of Two

open access: yesThe Scientific World Journal, 2013
I present a new algorithm for computing binomial coefficients modulo . The proposed method has an preprocessing time, after which a binomial coefficient with can be computed modulo in time.

Negation of binomial coefficients

open access: yesDiscrete Mathematics, 2008
We extend the concept of a binomial coefficient to all integer values of its parameters. Our approach is purely algebraic, but we show that it is equivalent to the evaluation of binomial coefficients by means of the @C-function. In particular, we prove that the traditional rule of ''negation'' is wrong and should be substituted by a slightly more ...

Developing and Evaluating a Laboratory‐Based Frailty Index for the Prediction of Long‐Term Health Outcomes in Systemic Lupus Erythematosus

open access: yesArthritis Care &Research, EarlyView.
Objective We aimed to construct and evaluate the first laboratory‐based frailty index (FI‐Lab) for predicting adverse outcomes in systemic lupus erythematosus (SLE) and to compare its predictive ability to that of an existing clinical FI. Methods We used data from a single‐center prospective cohort of adult patients with SLE whose baseline visit ...

Some properties of binomial coefficients and their application to growth modelling

open access: yesArab Journal of Basic and Applied Sciences, 2018
Some properties of diagonal binomial coefficients were studied in respect to frequency of their units’ digits. An approach was formulated that led to the use of difference tables to predict if certain units’ digits can appear in the values of binomial ...

Correlated Charge Transport in an Organic Coulomb Glass

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Advances in the development of organic field‐effect transistors (OFETs), electrically gated organic semiconductors (EGOFETs), and organic electrochemical transistors (OECTs) allow for the operation of these devices at very high charge‐carrier densities, where Coulomb interactions between carriers can be expected to become significant.

TME/NIR Dual‐Responsive Zinc‐Based Targeted Nanoagonist for Multimodal Amplification of STING‐Mediated Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A multifunctional nanoagonist (cDZ@IP) enables nano‐metabolite–driven multimodal activation of the STING pathway and enhanced immune recognition, achieving potent antitumor immunity and suppressing tumor growth and metastasis. This strategy highlights the rational design of therapeutic metabolites and establishes a new paradigm bridging nanomedicine ...

Vieta's triangular array and a related family of polynomials

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
If n≥1, let the nth row of an infinite triangular array consist of entries B(n,j)=nn−j(jn−j), where 0≤j≤[12n].

Quotients of sequences under the binomial convolution [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
This paper gives expressions for the solution {a(n)} of the equation Σ_{k=0}^{n} (n choose k)a(k)b(n-k)=c(n),n=0,1,2,..., where b(0) ≠ 0, that is, of the equation a ○ b = c in a, where ○ is the binomial convolution.
