Live-trapping of animals in natural populations is one of the main ways to determine population processes. We examined the effects of live-trapping on the expression of N-methyl-d-aspartate (NMDA) receptor subunits in the hippocampus of snowshoe hares. Snowshoe hares were obtained either with or without the stress of live-trapping. The CA1, CA3 and dentate gyrus were dissected and analyzed for ...

This paper discusses time-dependent dielectric breakdown (TDDB) in n-FETs with HfSiON gate stacks under various stress conditions. It was found that the slope of Weibull distribution of Tbd, Weibull β, changes with stress conditions, namely, DC stress, unipolar AC stress and bipolar AC stresses. On the other hand, the time evolution component of stress-induced leakage current (SILC) was not cha...

An inherent weakness of waveguide based optofluidic trapping [1] is that only a small fraction of the total power is used in trapping and transporting particles. In the best case scenario, 25% power is lost in coupling into the waveguide, and of the remaining energy, only 10-15% is present in the evanescent field. Ultimately, only 7-12% of the input power is actually used for trapping. Here we ...

BACKGROUND Cyprus is recognised as a hotspot for illegal bird trapping in the Mediterranean basin. A consumer demand for the Eurasian blackcap (Sylvia atricapilla) is driving the use of non-selective trapping methods, resulting in the indiscriminate killing of millions of migratory birds. Efforts to tackle the issue have so far been characterised mostly by a top-down approach, focusing on legis...

PURPOSE To compare thin-section computed tomographic (CT) scans obtained during suspended end expiration with helical CT scans obtained during continuous expiration for the assessment of air trapping. MATERIALS AND METHODS Forty-nine patients with an airway disease were examined with suspended-end-expiration CT after a 6-8-second expiratory maneuver, which was followed with continuous-expirat...

OBJECTIVE To investigate the diagnostic value of different patient positions during expiratory low-dose thin-layer multidetector computed tomography (MDCT) for detecting air trapping after allogeneic hematopoietic stem cell transplantation (allo-HSCT). PATIENTS AND METHODS Expiratory lung MDCT scanning was done for 51 post-allo-HSCT patients in both the supine and prone positions to determine...

Silicon diodes fabricated on oxygenated and non-oxygenated silicon wafers with different bulk resistivities (1, 2 and 15 kO cm) were irradiated with neutrons, pions and protons to fluences up to 2:4 10 n=cm : Effective trapping times for electrons and holes were determined by the charge correction method in the temperature range between 501C and 201C: The measured effective trapping probabiliti...

Understanding the maximal enhancement of solar absorption in semiconductor materials by light trapping promises the development of affordable solar cells. However, the conventional Lambertian limit is only valid for idealized material systems with weak absorption, and cannot hold for the typical semiconductor materials used in solar cells due to the substantial absorption of these materials. He...

The poor efficiency of microfluidic single cell trapping is currently restricting the full potential of state-of-the-art single cell analyses. Using fluid dynamics simulations in combination with particle image velocimetry to systematically optimize trap architectures, we present a microfluidic chip with enhanced single cell trapping and on-chip culture performance. Upon optimization of trap ge...

A double nanohole in a metal film can optically trap nanoparticles such as polystyrene/silica spheres, encapsulated quantum dots and up-converting nanoparticles. Here we study the dynamics of trapped particles, showing a skewed distribution and low roll-off frequency that are indicative of Kramers-hopping at the nanoscale. Numerical simulations of trapped particles show a double-well potential ...
