Creating long-lived neutral-atom traps in a cryogenic environment [PDF]

open access: yes, 1995
We describe techniques for creating long-lived magneto-optical and magnetostatic traps for neutral atoms. These traps exist in a sealed cryogenic environment with a temperature near 4 K, where the background gas pressure can be extremely low.

Time Spent by Calliphora Spp. Blowflies on Standard Traps Baited with Liver and Ammonia

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The larvae of blowflies from the Calliphoridae family cause fly strikes in sheep and other species of economic importance. Impaired wool, decrease of ewe fertility, and even death can occur in heavy infestations.

The fauna of small mammals in the vicinity of Temerin, The Vojvodina providence [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2006
The samples collected by traps in the vicinity of Temerin and the analysis of pellets of the long-eared owl (Asia otus) and the barn owl (Tyto alba) served as a basis for the determination of 409 individuals of small mammals of the orders Insectivora and

Stagnation Traps [PDF]

open access: yesThe Review of Economic Studies, 2017
We provide a Keynesian growth theory in which pessimistic expectations can lead to very persistent, or even permanent, slumps characterized by high unemployment and weak growth. We refer to these episodes as stagnation traps, because they consist in the joint occurrence of a liquidity and a growth trap.

Clinical and Genetic Characteristics, Target Therapy Results in Children with Traps Syndrome (on Clinical Surveillance Data)

open access: yesНаучно-практическая ревматология, 2021
The complexity of diagnosing and predicting the course of TNF-receptor-associated periodic syndrome TRAPS determines the importance of studying the dependence of clinical manifestations on the variant of genetic mutation and the presence of modifier ...

Dynamic Control of Photoresponse in ZnO-Based Thin-Film Transistors in the Visible Spectrum

open access: yesIEEE Photonics Journal, 2013
We present ZnO-channel thin-film transistors with actively tunable photocurrent in the visible spectrum, although ZnO band edge is in the ultraviolet. ZnO channel is deposited by atomic layer deposition technique at a low temperature (80 $^{\circ}\hbox{C}

Fullerene van der waals Oligomers as electron traps [PDF]

open access: yes, 2014
Density functional theory calculations indicate that van der Waals fullerene dimers and larger oligomers can form interstitial electron traps in which the electrons are even more strongly bound than in isolated fullerene radical anions.

Excitons in Electrostatic Traps

open access: yes, 2005
We consider in-plane electrostatic traps for indirect excitons in coupled quantum wells, where the traps are formed by a laterally modulated gate voltage.

A Study in the Summer Phenology of Dionychious Spiders from Northern Minnesota Forests [PDF]

open access: yes, 2017
Dionychious ground layer spiders from Larix and Populus stands were collected by pitfall traps. The typical pattern of dominant, influent and accessory species was well marked. Populus stands had greater diversity of species than Larix stands.

Photocarrier transport dynamics in lifetime and relaxation regimes of semiconductors containing traps

open access: yesMaterials Research Express, 2019
High resistivity semiconductors used in various optoelectronic devices, such as radiation detectors and photoconductive switches, usually require electrical compensation involving deep level defects, which are also closely related to the photocarrier ...
