We study the mechanics of Hayward's trapping horizons, taking isolated horizons as equilibrium states. Zeroth and second laws of dynamic horizon mechanics come from the isolated and trapping horizon formalisms, respectively. We derive a dynamical first law by introducing a new perturbative formulation for dynamic horizons in which "slowly evolving" trapping horizons may be viewed as perturbativ...

We have used diffusive mixing and dielectrophoretic trapping to lyse Escherichia coli cells in a microfabricated environment and trap the E. coli chromosome. We characterize the conditions needed for efficient lysis of the cells, and conditions needed for the dielectrophoretic trapping of the chromatin without the trapping of cytoplasmic proteins.

Radiation-induced charge trapping has been studied in cured hydrogen silsesquioxane low dielectric constant films subjected to electric fields during the radiation process. Evidence is found for electric field-dependent negative charge trapping with a dose 47 variation. The possible origin of the negative charge trapping is discussed.

Introduction: According  to  the  latest  statistical  and  epidemiological  studies,  COPD  will  become  the  fourth  leading  cause  of  death  in  2030  worldwide.  Scientists  are  studying  on  methods  to  diagnose  COPD  in  the  patients  in  early  stages,  because  it  is  a  curable  and  preventable  disease  in  early  stages.  In  this  study,  evidences  of  hyperinflation  on  ...

Traps for monitoring of flying insect pests constitute a critical part of integrated pest management strategies. However, interpretation of trap captures is hampered by 1) factors associated with the performance of traps (i.e., lure, trap design, placement); 2) an often poorly defined relationship between trap captures and population density; and 3) interpretation approaches being highly specif...

UNLABELLED Poly(ADP-ribose) polymerases (PARP1, -2, and -3) play important roles in DNA damage repair. As such, a number of PARP inhibitors are undergoing clinical development as anticancer therapies, particularly in tumors with DNA repair deficits and in combination with DNA-damaging agents. Preclinical evidence indicates that PARP inhibitors potentiate the cytotoxicity of DNA alkylating agent...

Differences in the degree of trapping of initial block by N-methyl-D-aspartate (NMDA) receptor antagonists may affect their safety and, hence, suitability for clinical trials. In this comparative study, 23 compounds structurally related to the low-affinity, use-dependent NMDA receptor antagonist (S)-alpha-phenyl-2-pyridineethanamine dihydrochloride (AR-R15896AR) were examined to determine the d...

We design and numerically simulate a photonic crystal waveguide cavity with a nanoslot structure for single nanoparticle trapping. A 135x enhancement of optical gradient trapping force compared to plain waveguide trapping devices has been achieved. ©2009 Optical Society of America OCIS codes: (350.4855) Optical tweezers or optical manipulation; (350.4238) Nanophotonics and photonic crystals
