Crystal growth and Witt rings

open access: yesJournal of Algebra, 1991
The notion of mathematical crystal growth was used by D. A. Klarner [Kl, K2] to study spreading of information in a large computer net. His main result states that the generating function of a growing crystal is always a rational function with explicitly determined denominator. In a quite different context, W.

Edad y crecimiento del híbrido de tilapia Oreochromis niloticus x Oreochromis aureus (Perciformes: Cichlidae) en la represa “Zimapán” Hidalgo, México

open access: yesRevista de Biología Tropical, 2011
La edad y crecimiento de la tilapia Oreochromis niloticus x Oreochromis aureus fueron determinados por medio de la lectura de escamas. Un total de 382 individuos fueron capturados mediante el uso de redes agalleras y atarrayas.

Effects of pruning on heartwood formation in Scots pine trees

open access: yesJournal of Forest Science, 2004
The object of this study was to investigate the effect of pruning on heartwood formation in mature Scots pine (Pinus sylvestris L.) trees. Fifty trees were treated by three different intensive pruning regimes: 42, 60 and 70 percentage of defoliation ...

Rings with subexponential growth and irreducible representations [PDF]

open access: yesProceedings of the American Mathematical Society, 1978
Some monoids and algebras are constructed with growth which is subexponential but not polynomially bounded. The algebras have homomorphic images which are primitive with polynomially bounded growth, but which do not satisfy a Nullstellensatz-type of property.

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

open access: yesFEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Computer reconstruction of pine growth rings using MRI

open access: yesMagnetic Resonance Imaging, 2004
This work explores the use of magnetic resonance imaging (MRI) for nondestructive determination of wood characteristics and for 3D wood modeling. In this context, one of the applications under development is the automatic recognition and reconstruction of rings from transversal images obtained from MRI scanners.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...
