Abstract We propose an experiment based on a Bose–Einstein condensate interferometer for strongly constraining fifth-force models. Additional scalar fields from modified gravity or higher dimensional theories may account dark energy and the accelerating expansion of Universe. These have led to proposed screening mechanisms fit within tight experimental bounds searches. show that our would greatly improve existing constraints these models by many orders magnitude.

Effective workplace violence (WPV) prevention programs are essential, yet challenging to implement in healthcare. The aim of this study was identify major barriers implementation effective programs. After reviewing the related literature, authors describe their research methods and analysis report following seven themes as programs: a lack action despite reporting; varying perceptions violence; bullying; profit-driven management models; accountability; focus on customer service; weak social...

Understanding the nature of dark energy and matter is one modern physics' greatest open problems. Scalar-tensor theories with screened scalar fields like chameleon model are among most popular proposed solutions. In this article, we present first analysis impact a field on dynamical Casimir effect, whose main feature particle production associated resonant condition boundary periodic motion in cavities. For this, employ recently developed method to compute evolution confined quantum globally...

Many entry-level and experienced healthcare professionals have not received training in workplace violence prevention strategies.

Objective: The aim of this study was to examine nurses' knowledge the state New Jersey (NJ) Violence Prevention in Health Care Facilities Act, workplace violence training, and experience with violence. Methods: In 2013, 309 (22.5% response rate) nurses returned a mailed survey. Univariate multivariate analyses were conducted. Results: Ninety percent respondents female. When perpetrator patient or family member, experienced verbal abuse most (57.8%), followed by threats (52.3%), physical...

The recent detections of gravitational waves (GWs) by the LIGO and Virgo collaborations have opened field GW astronomy, intensifying interest in GWs other possible detectors sensitive different frequency ranges. Although strong producing events are rare currently unpredictable, can principle be simulated analogue systems at will lab. Simulation a manifestly quantum system would allow for study interaction phenomena with GWs. Such predicted is exploited recently proposed Bose-Einstein...

An online NIOSH course raises awareness of workplace violence and offers preventive strategies.

As businesses dealt with an increasingly anxious public during the COVID-19 pandemic and were frequently tasked enforcing various prevention policies such as mask mandates, workplace violence harassment (WPV) emerged increasing important issue affecting worker safety health. Publicly available media reports searched for WPV events related to that occurred 1 March 2020, 31 August 2021, using Google News aggregator services scans data abstraction verification. The search found 408 unique...

Additional scalar fields from scalar-tensor, modified gravity or higher dimensional theories beyond general relativity may account for dark energy and the accelerating expansion of Universe. These have lead to proposed models screening mechanisms, such as chameleon symmetron fields, tight experimental bounds on fifth-force searches. Cold atom systems been very successfully used constrain parameters these models, in future eliminate interesting parameter space some entirely. In this paper, we...

Approximately eight nonfatal violent workplace crimes were reported per 1,000 U.S. workers during 2007–2015; 58% of not to police. Highest rates crime among protective services, community and social health care occupations.

The objective of the study was to report on what violence-based training home health care aides received, their participation in promotion classes, and aides' experience with workplace violence. In 2013, a mail survey completed by 513 state New Jersey. Ninety-four percent respondents were female. Respondents whose agency part hospital more likely receive safety than not (p = .0313). When perpetrator violence patient or family member, experienced verbal abuse most (26%), then physical assault...

Workplace assaults against healthcare workers originate from many sources, but are predominantly committed by patients. Therefore, training in strategies for preventing patient-on-nurse violence is very important throughout a nurse's career.The online course described this article presents prevention the institutional and individual levels. These reinforced video case studies of five real-life incidents with key learning points discussed.The physical psychological consequences workplace can...

We develop a general vectorial model of two-frequency nonlinear pulse propagation in multi-mode optical waveguides, including mixing effects between modes and polarizations across both frequencies, resulting nontrivial new terms the amplitude equations. present rules for calculating these from simple diagrammatic representations physical processes. The corresponding coefficients are computed numerically step index fiber, demonstrating that even simplest case cylindrical significant...

Coherent control of quantum transitions -- indispensable in technology generally relies on the interaction systems with electromagnetic radiation. Here, we theoretically demonstrate that non-radiative near-field a temporally modulated free-space electron beam can be utilized for coherent systems. We show such manipulation performed only classical over itself, and is readily realizable current technology. This approach may provide pathway towards spectrally selective nano-scale spatial...

The National Traumatic Occupational Fatalities surveillance system recorded 1518 fire- and flame-related occupational fatalities among the civilian workforce in United States between 1980 1994. resulted from 1221 separate incidents, of which 122 involved more than one victim accounted for 419 deaths. Nearly 4 10 resulting a multiple-victim fire were workers manufacturing industry. Similarly, highest frequency single-victim events, over fourth, manufacturing. For fourth within each event...

Effective security is crucial to the functioning of a hospital because it impacts patient care, employee satisfaction and turnover, confidence in healthcare facility provide safe environment for medical care. A survey was conducted NJ directors describe their programs, assess compliance with statewide workplace violence prevention regulations, evaluate influence experience opinions on comprehensiveness program. The surveyed programs (n = 52) had partial 35) viewed regulations positively but...

Abstract Ensembles of ultra-cold atoms have been proven to be versatile tools for high precision sensing applications. Here, we present a method the manipulation state trapped clouds bosonic atoms. In particular, discuss creation coherent and squeezed states quasiparticles coupling quasiparticle modes through an external cavity field. This enables operations like swapping beam splitting which can applied realize Mach–Zehnder interferometer (MZI) in frequency space. We two explicit example...
