The Higgs sector of the Minimal Supersymmetric Model (MSSM) is a CPconserving two-Higgs doublet model that depends, at tree-level, on two Higgs sector parameters. In order to accurately determine the phenomenological implications of this model, one must include the effects of radiative corrections. The leading contributions to the one-loop radiative corrections are exhibited; large logarithms a...

We consider neural network models described by systems of (continuous time) differential equations. Th e dynamical nature of each model is identified, symmet ric networks being relat ed to gradient vector fields and asymmet ric networks decomposed into their gradient and Hamilt onian components . From thi s identification follows, in particular , a simple characterizat ion of st ructural stabil...

The development of an "artificial photosynthetic system" (APS) having both the analogous important structural elements and reaction features of photosynthesis to achieve solar-driven water splitting and CO₂ reduction is highly challenging. Here, we demonstrate a design strategy for a promising 3D APS architecture as an efficient mass flow/light harvesting network relying on the morphological re...

In today’s accelerating world economy, the drive to continually cut costs and focus on core competencies has driven many to outsource some or all of their production. In this environment, improving supply chain execution and leveraging the supply base through effective supplier relationship management (SRM) has become more critical than ever in achieving competitive advantage. It was found that...

To determine the effect of the removal of the tube on ovarian function we studied 52 artificial reproduction technology cycles in 26 women before and after undergoing laparoscopic salpingectomy for ectopic pregnancy. Ovarian response was measured by the duration and quantity of human menopausal gonadotrophins used in the cycle, the pre-ovulatory concentrations of oestradiol, the number of oocyt...

The artificial chromosome represents a useful tool for gene transfer, both as cloning vectors and in chromosome biology research. To generate a Plasmodium artificial chromosome (PAC), we had to first functionally identify and characterize the parasite's centromere. A putative centromere (pbcen5) was cloned from chromosome 5 of the rodent parasite P. berghei based on a Plasmodium gene-synteny ma...

This paper presents a new model for the development of artificial creatures from a single cell. The model aims at providing a more biologically plausible abstraction of the morphogenesis and the specialization process, which the organogenesis follows. It is built upon three main elements: a cellular physics system that simulates division and intercellular adhesion dynamics, a simplified cell cy...

Nanogold-based materials are promising candidate tools for nanobased medicine. Nevertheless, no conclusive information on their cytotoxicity is available. In the present study, we investigated the effects of gold nanoparticles (AuNPs) on human astrocytes in vitro. Nanogold treatment in a wide range of concentrations did not result in cytotoxicity. In contrast, nanogold provoked changes in the a...

We study the dynamics of a scalar inflaton field with a symmetric double– well potential and prove rigorously the existence of a limit cycle in its phase space. By using analytical and numerical arguments we show that the limit cycle is stable and give an analytical formula for its period.
