On Number of Compositions of Natural Numbers

open access: yes, 2010
We first give a combinatorial interpretation of coefficients of Chebyshev polynomials, which allows us to connect them with compositions of natural numbers. Then we describe a relationship between the number of compositions of a natural number in which a certain number of parts are p-1, and other parts are not less than p with compositions in which all

A Composition Theorem for Parity Kill Number [PDF]

open access: yes2014 IEEE 29th Conference on Computational Complexity (CCC), 2014
In this work, we study the parity complexity measures ${\mathsf{C}^{\oplus}_{\min}}[f]$ and ${\mathsf{DT^{\oplus}}}[f]$. ${\mathsf{C}^{\oplus}_{\min}}[f]$ is the \emph{parity kill number} of $f$, the fewest number of parities on the input variables one has to fix in order to "kill" $f$, i.e. to make it constant. ${\mathsf{DT^{\oplus}}}[f]$ is the depth

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Synthesis and properties of 0.3%Y2O3/0.3%La2O3/0.3%Al2O3/Cu composite

open access: yesScience and Engineering of Composite Materials, 2014
The 0.3%Y2O3/0.3%La2O3/0.3%Al2O3/Cu composite was prepared by oxygen and nitrogen atomization spray deposition technique, internal oxidation, and then treated by annealing at different temperatures.

Circulating histones as clinical biomarkers in critically ill conditions

open access: yesFEBS Letters, EarlyView.
Circulating histones are emerging as promising biomarkers in critical illness due to their diagnostic, prognostic, and therapeutic potential. Detection methods such as ELISA and mass spectrometry provide reliable approaches for quantifying histone levels in plasma samples.

A Review of Continuous Glucose Monitoring Based Composite Metrics for Glycemic Control.

open access: yesDiabetes Technology & Therapeutics, 2020
We performed a literature review of composite metrics for describing the quality of glycemic control, as measured by continuous glucose monitors (CGMs). Nine composite metrics that describe CGM data were identified.

Mechanisms and kinetic assays of aminoacyl‐tRNA synthetases

open access: yesFEBS Letters, EarlyView.
Accurate protein synthesis is crucial for life. The key players are aminoacyl‐tRNA synthetases (AARSs), which read the genetic code by pairing cognate amino acids and tRNAs. AARSs establish high amino acid selectivity by employing physicochemical limits in molecular recognition.
