Older adults with depression often present with signs and symptoms indicative of functional or cognitive impairment. These somatic symptoms make evaluating and treating depression in older adults more complex. Late life depression (LLD), depression in adults over the age of 65, is more frequently associated with cognitive changes. Cognitive impairment in LLD may be a result of the depressive di...

Thin palladium acetate films have been used for laser deposition (or prenucleation) of palladium lines, which can be used as a catalyst for electroless plating of other metals, notably Cu, to build up thicker conductors. This palladium deposition process was carried out using a CW argon ion laser at 514.5 nm for the first time in 1987 [l] then at 351 nm [2]. This visible-laser-induced depositio...

We demonstrate a method using a spatial light modulator (SLM) to generate arbitrary 2-D spatial configurations of laser induced cavitation bubbles. The SLM acts as a phase hologram that controls the light distribution in the focal plane of a microscope objective. We generate cavitation bubbles over an area of 380 x 380 microm(2) with a 20x microscope objective through absorption of the pulsed l...

Changes in brain-derived neurotrophic factor (BDNF) level are implicated in the pathophysiology of cognitive decline in depression and neurodegenerative disorders in older adults. We aimed to evaluate the longitudinal association over two years between BDNF and persistent cognitive decline in individuals with remitted late-life depression and Mild Cognitive Impairment (LLD + MCI) compared to ei...

Laser removal of particles from solid surfaces was investigated both theoretically and experimentally. A cleaning model was established for laser-induced removal of particles from solid surfaces by taking Van der Waals force, capillary force and cleaning force into account. Laser cleaning forces are induced by fast thermal expansion of particles and/or solid surfaces irradiated by laser for dry...

BACKGROUND Patients with advanced hip arthritis can present with multifactorial limb length discrepancies (LLDs) owing to bony shortening from growth arrest, proximal hip migration, soft-tissue contractures, and pelvic obliquity. The patient perceives an LLD that is a combination of true LLD and apparent LLD. METHODS We retrospectively reviewed 7 cases with multifactorial mean perceived LLD o...

Excimer laser pulsed deposition was applied to the deposition of organic thin ®lms on sapphire and on glass. The thin ®lms were analyzed by X-ray diffraction (XRD), micro-Raman spectroscopy and ESCA. It was found that the properties of the ®lms were very close to that of the target materials. Strong photoluminescence was observed for both Alq3 and N,N 0-diphenyl-N,N 0-bis(3-methylphenyl)-(1,1 0...

Pulsed laser deposition method was employed to grow MgO thin films with preferred orientation on bare Si(100) and SiO2/Si(100) substrates. The orientation of MgO thin films was systematically investigated by varying deposition parameters. XRD analysis showed that the preferred orientation of MgO thin films would change from (111) to (100) when laser fluence decreased and oxygen pressure increas...

Here we report on the utilization of Laser-Induced Breakdown Spectroscopy (LIBS) for determination of Quantum Dots (QDs) in liquid solution. The process of optimization of experimental conditions from choosing the carrier medium to application of colloid QDs is described. The main goal was to get the best possible signal to noise ratio. The results obtained from the measurements confirmed the c...
