OBJECTIVES Late-life depression (LLD) is associated with reduced neurotrophic support and abnormalities in neurodegenerative cascades. The aim of the present study is to determine the concentrations of brain-derived neurotrophic factor (BDNF), amyloid-β42, total Tau, and phosphorylated Tau in the cerebrospinal fluid (CSF) of patients with LLD and cognitive impairment compared to healthy older a...

Laser-Induced Breakdown Spectroscopy (LIBS) is a spectroscopy-based measurement technique that capable of rapid and accurate qualitative, as well quantitative, analysis elemental ingredients either in solid (either for organic or inorganic compounds), liquid, gaseous samples. Unfortunately, this not the case powdered samples, where focused laser beam will disperse powder. This can be overcome b...

The OMEGA laser system uses waveplates and polarizers to alter the polarization of the laser light. Both devices are formed using two glass substrates that contain alignment layers and are separated by vacuum-deposited thin-film spacers and filled with liquid crystals (LCs). Vacuum deposition of thin-film spacers is time-consuming and requires the use of expensive equipment. In this study, spac...

Lateral lemniscus, a relay nucleus of auditory sensation, is involved in the control of phonatory movements such as human speech and vocalization of animals. The present study was designed to test whether neurons in the lateral lemniscus contributed to the control of swallowing, one of non-phonic oro-pharyngolaryngeal movements. In acutely decerebrated cats (n=15), swallowing was induced by ele...

BACKGROUND Late-life depression (LLD) is associated with a decline in physical activity. Typically this is assessed by self-report questionnaires and, more recently, with actigraphy. We sought to explore the utility of a bespoke activity monitor to characterize activity profiles in LLD more precisely. METHOD The activity monitor was worn for 7 days by 29 adults with LLD and 30 healthy control...

Computational modeling has a potential of making an important contribution to the advancement of laser-driven methods in nanotechnology. In this paper we discuss two computational schemes developed for simulation of laser coupling to organic materials and metals and present a multiscale model for laser ablation and cluster deposition of nanostructured materials. In the multiscale model the init...

The laser induced plasma in liquid hasn’t been studied enough. In liquid, the laser induced plasma may be able to resolve the hazardous material called the environment material. Then, the plasma produced in liquid by the laser light is studied and the plasma development is observed by a streak camera. The ultra pure water or the ultra pure water with a melted NaCl is used as a test liquid. The ...

Lithium has been utilized to enhance the plasma performance for a variety of fusion devices such as TFTR, CDX-U and NSTX. Lithium in both the solid and liquid states has been studied extensively for its role in hydrogen retention and reduction in sputtering yield. A liquid lithium diverter (LLD) was recently installed in the National Spherical Torus Experiment (NSTX) fusion reactor to investiga...

The main objective of the proposed linear laser driver (LLD) is to reduce signal distortion in an analog direct modulation configuration used for intermediate frequency over fiber links. This work draws on open-loop featuring two differential pair blocks a cascade arrangement achieve bandwidth measurement 415 MHz at half-power point, total harmonic 4.57% fundamental 100 MHz, and amplitude mVpp....
