Abstract

Electronic and dielectric properties of vapor-phase grown MoS_{2} have been investigated in metal/MoS_{2}/silicon capacitor structures by capacitance-voltage and conductancevoltage techniques. Analytical methods confirm the MoS_{2} layered structure, the presence of interfacial silicon oxide (SiO_{x}) and the composition of the films. Electrical characteristics in combination with theoretical considerations quantify the concentration of electron states at the interface between Si and a 2.5 - 3 nm thick silicon oxide interlayer between Si and MoS_{2}. Measurements under electric field stress indicate the existence of mobile ions in MoS_{2} that interact with interface states. Based on time-offlight secondary ion mass spectrometry, we propose OH^{-} ions as probable candidates responsible for the observations. The dielectric constant of the vapor-phase grown MoS_{2} extracted from CV measurements at 100 KHz is in the range of 2.6 to 2.9. The present study advances the understanding of defects and interface states in MoS_{2}. It also indicates opportunities for ion-based plasticity in 2D material devices for neuromorphic computing applications., Comment: 32 pages, manuscript and supplementary material

Abstract

From the 2002 data taking with a neutral kaon beam extracted from the CERN-SPS, the NA48/1 experiment observed 97 $\Xi^{0}\rightarrow \Sigma^{+} \mu^{-} \bar{\nu}_{\mu}$ candidates with a background contamination of $30.8 \pm 4.2$ events. From this sample, the BR($\Xi^{0}\rightarrow \Sigma^{+} \mu^{-} \bar{\nu}_{\mu}$) is measured to be $(2.17 \pm 0.32_{\mathrm{stat}}\pm 0.17_{\mathrm{syst}})\times10^{-6}$.

Abstract

The direct CP violation parameter Re(ε′/ε) has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. With 3.3 million KL → π0π0 events collected during the 1998 and 1999 running periods, a result of Re(ε′/ε) = (15.0 ± 2.7) × 10-4 has been obtained. The result combined with the published 1997 sample is Re(ε′/ε) = (15.3 ± 2.6) × 10-4.

Abstract

A study of the polarization of Λ hyperons produced in inelastic pN reactions induced by the 450 GeV proton beam from the CERN SPS has been performed with the NA48 detector. The Λ hyperons were detected at a fixed angle of 4.2 mrad in the momentum range from 50 GeV/c to 200 GeV/c. The polarization changes from -0.053 ± 0.034 to -0.298 ± 0.074 for a transverse momentum range of the Λ between 0.28 GeV/c and 0.86 GeV/c. The Λ̄ polarization is consistent with zero.

36. Exploring residents' perceptions of PA and NP roles and barriers to collaboration

Abstract

Objective: Developing competencies for interprofessional collaboration, including understanding other professionals' roles on interprofessional teams, is an essential component of medical education. This study explored resident physicians' perceptions of the clinical roles and responsibilities of physician assistants (PAs) and NPs in the clinical learning environment.Methods: Using a constructivist grounded theory approach, semistructured interviews were conducted with 15 residents in one academic setting. Transcripts were analyzed using an iterative approach to inductive coding.Results: Participants typically perceived PAs' and NPs' roles as being "like a resident," less commonly as independent clinicians, and rarely as collaborators. Barriers to understanding PA and NP roles and perceiving them as collaborators included the lack of preparatory instruction about PAs and NPs, the hierarchical structure of medical education, and inadequate role modeling of interprofessional collaboration.Conclusions: This study suggests that barriers in the clinical learning environment and the structure of medical education itself may impede residents' learning about PAs and NPs and how to collaborate with them.
