The b-$\tau$-unification in GUTs with non-chiral matter

open access: yes, 1997
It is shown, that the presently accepted value for b-quark mass can be obtained from the requirement of the exact b-$\tau$ unification in the both non-SUSY and SUSY non-chiral extended GUTs.Comment: 10 pages, LaTeX, 4 LaTeX figures ...

Space-time singularities and the axion in the Poincare coset models ISO(2,1)/H [PDF]

open access: yes, 1996
By promoting an invariant subgroup $H$ of $ISO(2,1)$ to a gauge symmetry of a WZWN action, we obtain the description of a bosonic string moving either in a curved 4-dimensional space--time with an axion field and curvature singularities or in 3 ...

Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes

open access: yesAdvanced Functional Materials, EarlyView.
Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...

Clonal stability of latex yield in eleven clones of Hevea brasiliensis Muell. Arg.

open access: yesGenetics and Molecular Biology, 2003
Eleven Hevea brasiliensis clones were evaluated for clonal stability of latex yield. A randomized complete block design was used with four replicates, two locations, seven years and three periods per year. Stability analysis was based on clone x year and

Spherical Vesicles Distorted by a Grafted Latex Bead: An Exact Solution

open access: yes, 2007
We present an exact solution to the problem of the global shape description of a spherical vesicle distorted by a grafted latex bead. This solution is derived by treating the nonlinearity in bending elasticity through the (topological) Bogomol'nyi ...

Translation-finite sets, and weakly compact derivations from $\lp{1}(\Z_+)$ to its dual [PDF]

open access: yes, 2005
We characterize those derivations from the convolution algebra $\ell^1({\mathbb Z}_+)$ to its dual which are weakly compact. In particular, we provide examples which are weakly compact but not compact.

A Bioengineered Model of the Human Cornea for Preclinical Assessment of Human Ocular Exposure to Environmental Toxicants

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
This paper presents a microphysiological system containing an array of individually addressable living corneal tissues constructed using primary human cells. The bioengineered eye model can simulate acute exposure of the human cornea to different types of environmental toxicants and provides a novel platform for visualization and quantitative ...

Natural rubber latex used as drug delivery system in guided bone regeneration (GBR)

open access: yesMaterials Research, 2009
In this work, we propose natural rubber latex (NRL) membranes as a protein delivery system. For this purpose Bovine Serum Albumin (BSA) was incorporated into the latex solution for in vitro protein delivery experiments.

Unraveling the roles of genotype and environment in the expression of plant defense phenotypes

open access: yesEcology and Evolution, 2021
Phenotypic variability results from interactions between genotype and environment and is a major driver of ecological and evolutionary interactions. Measuring the relative contributions of genetic variation, the environment, and their interaction to ...
