A program code to simulate neutron interactions with a CR-39 detector and calculate parameters describing the induced etched proton tracks in the CR-39 material was previously developed(( 1)). This code was used to understand the mechanisms involved during interactions with neutrons in the CR-39 material and the influence of the etching process, enabling an improvement in the efficiency of the ...

We report on the fabrication and characterization of solid-state thermal neutron detectors with detection areas up to 16 cm that require only a single preamplifier for data acquisition. These detectors consist of a honeycomb-like micro-structured Si diode with boron-10 filled deep holes. A continuous p–n junction formed over the entire surface of the microstructure helps to achieve a low leakag...

objectives: scaling and root planing (srp) is one of the most commonly used procedures during periodontal treatment. the aim of this study was to evaluate the root surface roughness after srp with erbium: yttrium aluminum garnet (er:yag) laser compared to ultrasonic and hand instruments.   materials and methods: in this experimental study, 56 extracted sound single-rooted teeth with moderate le...

background and objectives: bacillus species are attractive industrial organisms due to their rapid growth rates leading to a short fermentation cycle and for their capacity to secrete important enzymes and proteins such as xylanase into the extracellular medium. considering the industrial importance of xylanase, in this current study, bacillus spp. were isolated from different soils and were sc...

This communication presents the main results about the design and in-house fabrication of a new solid-state neutron detector, which produces a DC output signal proportional to the thermal neutron fluence rate. The detector has been developed within the framework of the 3-y project NESCOFI@BTF of INFN (CSN V). Due to its sensitivity, photon rejection, low cost and minimum size, this device is su...

This report describes an all-solid state central tracker which is intended for use in a detector at the proposed DESY 500 GeV electron-positron linear collider or a similar accelerator. The precise position measurements from position-sensitive silicon detectors give the tracker an outstanding momentum resolution for high momentum tracks: σp/p 2 = 3.6× 10 (GeV/c) for tracks perpendicular to the ...

We consider a two-level quantum system ~qubit! that is continuously measured by a detector. The information provided by the detector is taken into account to describe the evolution during a particular realization of the measurement process. We discuss the Bayesian formalism for such ‘‘selective’’ evolution of an individual qubit and apply it to several solid-state setups. In particular, we show...

The Bayesian formalism for a continuous measurement of solid-state qubits is extended to a model which takes into account several factors of the detector nonideality. In particular, we consider additional classical output and backaction noises ~with finite correlation!, together with quantum-limited output and backaction noises, and take into account possible asymmetry of the detector coupling....
