A polynomial Freiman-Ruzsa inverse theorem for function fields

Discrete Analysis
A polynomial Freiman-Ruzsa inverse theorem for function fields, Discrete Analysis 2025:24, 11 pp. A recent result of Gowers, Green, Manners and Tao gave a proof of Freiman's theorem in $\mathbb F_q^n$ with a polynomial dependence, thereby establishing a

Non-Parametric Estimation of the Renewal Function for Multidimensional Random Fields

Mathematics
This paper addresses the almost sure convergence and the asymptotic normality of an estimator of the multidimensional renewal function based on random fields. The estimator is based on a sequence of non-negative independent and identically distributed (i.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

FEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Terahertz Light-Field Imaging With Silicon Technologies

IEEE Open Journal of the Solid-State Circuits Society
The terahertz (THz) frequency range is widely considered the most challenging and underdeveloped frequency range due to the lack of technologies to effectively bridge the transition region between microwaves (below 100 GHz) and optics (above 10 000 GHz).

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Electromagnetic Fields as Structure-Function Zeitgebers in Biological Systems: Environmental Orchestrations of Morphogenesis and Consciousness

Frontiers in Integrative Neuroscience, 2014
Within a cell system structure dictates function. Any interaction between cells, or a cell and its environment, has the potential to have long term implications on the function of a given cell and emerging cell aggregates.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

On some differences between number fields and function fields

, 2016
The analogy between the arithmetic of varieties over number fields and the arithmetic of varieties over function fields is a leading theme in arithmetic geometry. This analogy is very powerful but there are some gaps.

The genus fields of Kummer function fields

Journal of Number Theory, 2003
For an algebraic function field \(E/k\) over the rational function field \(k=\mathbb{F}_q (t) \) with finite \(\mathbb{F}_q \), the author gives a definition of its genus field \(G(E)\) in analogy to that for a number field \(E/\mathbb{Q}\), namely \(G(E)\) is the maximal abelian subextension of the Hilbert class field of \(E\) (i.e. maximal unramified
