Semi-discrete models are a particular class of hybrid dynamical systems that undergo continuous dynamics most of the time but repeatedly experience discrete changes at some given moments. In the life sciences, since the first semi-discrete model was derived to describe population dynamics by Beverton & Holt (Beverton & Holt 1957 In Fisheries investigations, series 2, vol. 19), a large body of l...

Holt-Oram syndrome is a rare inherited disorder involving the hands, arms, and the heart. The defects involve carpal bones of the wrist and the thumb and the associated cardiac anomalies like atrial or ventricular septal defects. Congenital cardiac and upper-limb malformations frequently occur together and are classified as heart-hand syndromes. The most common amongst the heart-hand disorders ...

Two new approaches foi the multivariate analysis of fish growth in aquaculture are presented. The first of these two approaches, the "extended Bayley plot" is a multiple regression expansion of an existing bivariate method, which permits the inclusion of environmental and treatment variables when estimating the parameters Lm and K of the von Bertalanflj. growth function, given precise measureme...

Background: Intermittent cold stress delays flowering. This results from interaction between the cold and photoperiodic pathways. Results: CO protein is degraded through an HOS1-mediated ubiquitination mechanism during brief cold treatments. Conclusion: CO acts as a molecular hub that integrates photoperiod and cold signals into the flowering genetic pathways. Significance: The CO-HOS1 module i...

One of the most significant and well-known properties of entangled states is that they may lead to violations of Bell inequalities and are thus inconsistent with any local-realistic theory. However, there are entangled states that cannot violate any Bell inequality, and in general the precise relationship between entanglement and observable nonlocality is not well understood. We demonstrate tha...

BACKGROUND The occurrence of an anorectal malformation with Holt-Oram syndrome, microcephaly, and bilateral corneal opacity is rare and to the best of our knowledge has not previously been reported in the literature. Hence, there is a need to document our experience in this case and learn as much as possible from it. CASE PRESENTATION We present the case of a Nigerian female neonate with a po...

Semen samples from 9 sexually mature dogs of different breeds, aged from 1 to 5 years were used. Quality of sperm was evaluated using the following parameters: progressive motility (subjective), then structural and functional integrity of spermal membrane (supravital colouring (eosine/nigrosine) and HOS test). The majority of HOS reactive or swollen spermatozoa was placed in a hypoosmolar solut...

This is the simplest form of exponential smoothing and can be used only for data without any systematic trend or seasonal components. Given such a time series, a sensible approach is to take a weighted average of past values. So for a series, y 1 , y 2 ,…, y n , the estimate of the value of y n+1 , given the information available up to time n, is: y w y w y w y or i n i i n n y w y − ∞ = + ∑ = ...
