We prove existence of globally stable quasistatic evolutions, referred to as energetic solutions, for a model proposed by Marigo and Kazymyrenko in 2019. The behaviour geomaterials under compression is studied through the coupling Drucker–Prager plasticity with damage term tuning kinematical hardening. This provides new approach modelling geomaterials, which non associative usually employed. ha...
We model experience-dependent plasticity in the cortical representation of whiskers (the barrel cortex) in normal adult rats, and in adult rats that were prenatally exposed to alcohol. Prenatal exposure to alcohol (PAE) caused marked deficits in experience-dependent plasticity in a cortical barrel-column. Cortical plasticity was induced by trimming all whiskers on one side of the face except tw...
Brain damage resulting in loss of sensory stimulation can induce reorganization of sensory maps in cerebral cortex. Previous research on recovery from brain damage has focused primarily on adaptive plasticity within the affected modality. Less attention has been paid to maladaptive plasticity that may arise as a result of ectopic innervation from other modalities. Using ferrets in which neonata...
To understand and model damage generated during impact by a penetrator of ultra-high strength concrete targets, edge-on impact tests are performed with the so-called Ductal concrete, which is unreinforced or reinforced with short fibers. Two edge–on impact configurations are designed with a dynamic confinement system. The first configuration uses aluminum projectiles and allows us to study the ...
abstract background: determination of transgenic embryos from non transgenic embryos sibling is an important step in producing homozygous transgenic mice. these steps need by pcr or southern blotting followed extraction of dna, but both techniques require skill and consume time. objective: the aim of this study was simulation of high accuracy method using novel enhanced green fluorescent protei...
NMDA receptors (NMDARs) mediate ischemic brain damage, for which interactions between the C termini of NR2 subunits and PDZ domain proteins within the NMDAR signaling complex (NSC) are emerging therapeutic targets. However, expression of NMDARs in a non-neuronal context, lacking many NSC components, can still induce cell death. Moreover, it is unclear whether targeting the NSC will impair NMDAR...
Structural damage to r.c. buildings located in a near-fault area has been observed during strong ground motions, with long-duration horizontal pulses and high values of the ratio between the peak value of the vertical acceleration and the analogous value of the horizontal acceleration. The design provisions of current seismic codes are generally not very accurate for assessing the structural ef...
