Damage to the spinal cord disrupts the electrically active nerve cells w.ich normally transmit afferent and efferent signals,resulting in loss of motor,sensory,and autonomic *** treatments for spinal cord injury utilizing implanted spinal electrodes can be broadly classified into three different *** first of these approaches is“spinal stimulation”w.ere electrodes,usually positioned above the level of injury,provide electrical stimulation to target and disrupt pain signals before they reach the *** second approach uses“activity-dependent neuro-technologies”,in w.ich electrodes positioned below.the level of injury initiate a complex spatiotemporal pattern of stimulation at the lumbar spinal cord to generate a w.lking gait in the limbs(Minev et al.,2015;w.gner et al.,2018).

w. compare observed w.th predicted distributions of galaxy stellar masses M* and galaxy rest-frame ultra-violet luminosities per unit bandw.dth LUV, in the redshift range z=2 to 13. The comparison is presented as a function of the comoving w.rm dark matter free-streaming cut-off w.venumber kfs. For this comparison the theory is a minimal extension of the Press-Schechter formalism w.th only tw. parameters: the star formation efficiency, and a proportionality factor betw.en the star formation rate per galaxy and LUV. These tw. parameters are fixed to their values obtained prior to the James w.bb Space Telescope (Jw.T) data. The purpose of this comparison is to identify if, and w.ere, detailed astrophysical evolution is needed to account for the new.Jw.T observations.

w. summarize several measurements of the dark matter temperature-to-mass ratio, or equivalently, of the comoving root-mean-square thermal velocity of w.rm dark matter particles vhrms(1). The most reliable determination of this parameter comes from w.ll measured rotation curves of dw.rf galaxies by the LITTLE THINGS collaboration: vhrms(1)=406±69 m/s. Complementary and consistent measurements are obtained from rotation curves of spiral galaxies measured by the SPARC collaboration, density runs of giant elliptical galaxies, galaxy ultra-violet luminosity distributions, galaxy stellar mass distributions, first galaxies, and reionization. Having measured vhrms(1), w. then embark on a journey to the past that leads to a consistent set of measured dark matter properties, including mass, temperature and spin.
