OBJECTIVE To describe the prevalence of self-reported rates of auditory, visual, and dual sensory impairment (DSI) in Afghanistan and Iraq war Veterans receiving traumatic brain injury (TBI) evaluations. DESIGN Retrospective medical chart review. PARTICIPANTS Thirty-six thousand nine hundred nineteen Veterans who received a TBI evaluation between October 2007 and June 2009. Final sample inc...

PURPOSE We applied a novel diffusion spectrum imaging (DSI) acquisition to determine associations between aging and subcortical fiber tract integrity. MATERIALS AND METHODS We studied 35 cognitively healthy subjects (17 women), spanning the adult age range between 23 and 77 years, using anatomical MRI and a novel DSI acquisition scheme at 3 Tesla. The study was approved by the local instituti...

For a given family (Gi)i∈N of finitely generated abelian groups, we construct Dedekind domain D having the following properties. Pic(D)≅⨁i∈NGi. each i∈N, there exists submonoid Si⊆D• with Pic(DSi)≅Gi. Each class Pic(D) and all Pic(DSi) contains infinitely many prime ideals.

Despite having similar brains, related species can display divergent behaviors. Investigating the neural basis of such behavioral divergence can elucidate the neural mechanisms that allow behavioral change and identify neural mechanisms that influence the evolution of behavior. Fewer than three percent of Nudipleura (Mollusca, Opisthobranchia, Gastropoda) species have been documented to swim. H...

Introduction The diffusion spectrum imaging (DSI) technique can map intravoxel heterogeneity of molecular water diffusion and depict complex fiber architecture within tissue structures [1]. Theoretically, an extremely high maximum b-value (i.e., > 10000 s/mm) is necessary for good DSI reconstruction, though this is difficult to achieve due to limited signal-to-noise ratio (SNR). Previously, an ...

Peak-toaverage power ratio (PAPR) is one of the major problems of orthogonal frequency division multiplexing (OFDM). The larger PAPR signal may cause high out-of-band radiation, when the OFDM signal is passed through a radio frequency power amplifier. In literatures, many researchers proposed various methods to reduce PAPR. Among those, Dummy sequence Insertion (DSI) and partial transmit sequen...

Background Probing the microscale diffusion of water informs on cardiac microstructural features such as cell density and orientation. Diffusion spectrum imaging (DSI) is widely regarded as the gold standard as it measures diffusion in a model-free manner. However, acquisition times are prolonged due to high sampling requirements in qspace. Various methods of reducing acquisition times have bee...

This study aims to develop the Perceived Job Stress as an Academic Leader (PJSAL) instrument based on a modification of Dean's Inventory (DSI) (Wild, et al., 2003). DSI is selected because it can accurately identify potential sources stress for dean, which also applicable in context academic leadership general. involved 214 lecturers who responded PJSAL via Google Form. Its construct validity w...

Endocannabinoids (eCBs) act as retrograde messengers at inhibitory synapses of the hippocampal CA1 region. Current models place eCB synthesis in the postsynaptic pyramidal cell and the site of eCB action at cannabinoid (CB1) receptors located on presynaptic interneuron terminals. Four responses at the CA1-interneuron synapse are attributed to eCBs; depolarization-induced suppression of inhibiti...
