On a conjecture of Erdős on the sum ∑p ⩽ n 1(p log p)
Journal of Number Theory, 1991 AbstractA sequence A = {ai} of positive integers a1 < a2 < ⋯ is said to be primitive if no term of A divides any other. In this paper we prove the followingTheorem. If A = {ai} is a primitive sequence such that each ai has at most four prime factors, the factors being counted according to multiplicity, then ∑ai ⩽ n 1(ai log ai) ⩽ ∑p ⩽ n, 1(p log p) for

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA
FEBS Open Bio, EarlyView.PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

logcondens: Computations Related to Univariate Log-Concave Density Estimation [PDF]
Maximum likelihood estimation of a log-concave density has attracted considerable attention over the last few years. Several algorithms have been proposed to estimate such a density. Two of those algorithms, an iterative convex minorant and an active set

Effects of in-package cold plasma treatment on poultry breast meat packaged in high CO2 atmosphere
Poultry Science: High CO2 in packages significantly extends microbiological shelf life of poultry meat. Cold plasma is an emerging antimicrobial treatment, which generates various reactive gas species and inactivates microbials effectively.

microRNA-7-5p and α-Synuclein SAA Predict Parkinson's Disease Phenoconversion. [PDF]
Ann Clin Transl NeurolABSTRACT Objective Corroborate blood neuron‐derived extracellular vesicle (NDEV) alpha‐synuclein (αSyn), the CSF αSyn seed amplification assay (αSyn‐SAA), and blood microRNA‐7‐5p (miR‐7‐5p) as markers for Parkinson's disease (PD) phenoconversion and determine if combining these markers would help select subjects who would be more likely to phenoconvert.

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells
FEBS Open Bio, EarlyView.Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.
