Motivated by poor network connectivity from moving vehicles, we develop a new loss recovery method called opportunistic erasure coding (OEC). Unlike existing erasure coding methods, which are oblivious to the level of spare capacity along a path, OEC transmits coded packets only during instantaneous openings in a path’s spare capacity. This transmission strategy ensures that coded packets provi...

Lockdown measures during the COVID-19 pandemic have led to reductions in physical activity (PA) worldwide. Leading public health organizations recommended use of online exercise classes (OEC) compensate loss regular classes. As now, no data are available on uptake OEC and users’ attitudes. The aim current survey was assess attitudes towards Germany. Respondents indicated awareness OEC, levels a...

(Monooxooctaethylchlorinato)iron(III) chloride, (oxo-OEC)FeCl, 1, has been investigated by X-ray crystallography and by 1H NMR spectroscopy. Its bis(imidazole-d4) complex has been studied by multidimensional 1H NMR and EPR spectroscopies, and the results are compared to those for the bis(Im-d4) complex of (octaethylchlorinato)iron(III) chloride, (OEC)FeCl, 2. EPR and NMR results show that both ...

The interaction of oviductal epithelial cells (OECs) with the spermatozoa has beneficial effects on the sperm functions. The aim of this study is to evaluate the in vitro fertilizing capacity of incubating spermatozoa previously selected by density gradient in OEC and determinate some sperm characteristics that could explain the results obtained. In this study, we assessed in vitro fertilizatio...

background: transplantation approaches are interventions currently available to apply to the devastating problem of spinal cord injury (sci). olfactory ensheathing cell (oec) and embryonic stem cell (esc) are considered to be promising therapeutic strategies . in this study, we compared the potential use of oecs and neurally pre-differentiated escs in contusion spinal cord. methods: oecs were h...

OBJECTIVE This study is to investigate the effect of the combination of the olfactory ensheathing cells (OEC) transplantation and intravitreous injection of ciliary neurotrophic factor (CNTF) on the retinal ganglia cells' (RGC) apoptosis and axonals' reparation and regeneration. METHODS In this study, the supraorbital margin exposure of the optic nerves was used to establish adult SD rats' op...

BACKGROUND Oviduct epithelial cells (OEC) co-culture promotes in vitro fertilization (IVF) in human, bovine and porcine species, but no data are available from equine species. Yet, despite numerous attempts, equine IVF rates remain low. Our first aim was to verify a beneficial effect of the OEC on equine IVF. In mammals, oviductal proteins have been shown to interact with gametes and play a rol...

The inhibitory effect of Al3+on photosystem II (PSII) electron transport was investigated using several biophysical and biochemical techniques such as oxygen evolution, chlorophyll fluorescence induction and emission, SDS-polyacrylamide and native green gel electrophoresis, and FTIR spectroscopy. In order to understand the mechanism of its inhibitory action, we have analyzed the interaction of ...
