Iteration Distribution of Prime Numbers

open access: yesJournal of Mathematics Research, 2011
The distribution of prime numbers is given iteration function, iterated function transformation, series of transformations, the general term of iteration, calculation examples and numerical control.

Toward a dynamical model for prime numbers

open access: yes, 2004
We show one possible dynamical approach to the study of the distribution of prime numbers. Our approach is based on two complexity methods, the computable information content and the entropy information gain, looking for analogies between the prime ...

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

open access: yesMolecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Discrepancies in the distribution of prime numbers

open access: yesJournal of Number Theory, 1982
AbstractChebyshev has noticed a certain predominance of primes of the form 4n + 3 over those of the form 4n + 1. He asserted that limx→∞∑p > 2 (−1)(p − 1)2e−px = −∞. This was unproven until today. G. H. Hardy, J. E. Littlewood and E. Landau have shown its equivalence with an analogue to the famous Riemann hypothesis, namely, L(s, χ1mod 4) ≠ 0, Re(s ...

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

open access: yesMolecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

A question of Erdős and Graham on Egyptian fractions

open access: yesDiscrete Analysis
A question of Erdős and Graham on Egyptian fractions, Discrete Analysis 2025:28, 13 pp. An _Egyptian fraction_ is a way of writing a rational number as a sum of reciprocals of positive integers with distinct denominators.

Prime Numbers Distribution Line

open access: yes, 2020
During the analysis of the fractal-primorial periodicity of the natural series of numbers, presented in the form of an alternation (sequence) of prime numbers (1 smallest prime factor > 1 of any integer), the regularity of prime numbers distribution was revealed.

Applications of prime numbers

open access: yes, 2012
textThis report explores the historical development of three areas of study regarding prime numbers. The attempt to find an efficient and useful function to generate primes could be a helpful tool in the improvement of encryption.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

open access: yesFEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.
