Confined Quantum Time of Arrivals [PDF]

open access: yesPhysical Review Letters, 2004
We show that formulating the quantum time of arrival problem in a segment of the real line suggests rephrasing the quantum time of arrival problem to finding states that evolve to unitarily collapse at a given point at a definite time. For the spatially confined particle, we show that the problem admits a solution in the form of an eigenvalue problem ...

Dynamic Appointment Rescheduling of Trucks under Uncertainty of Arrival Time

open access: yesJournal of Marine Science and Engineering, 2022
The uncertainty of the arrival time of trucks has increased the complexity of terminal operations. The truck appointment system (TAS) cannot respond to this problem in time, which can easily cause appointment invalidation and reduce the efficiency of ...

Robot Evacuation on a Line Assisted by a Bike

open access: yesInformation, 2021
Two robots and a bike are initially placed at the origin of an infinite line. The robots are modelled as autonomous mobile agents whose communication capabilities are either in the wireless or face-to-face model, while the bike neither can move nor ...

Setting staffing requirements for time-dependent queueing networks: the case of accident and emergency departments [PDF]

open access: yes, 2012
An incentive scheme aimed at reducing patients’ waiting times in accident and emergency departments was introduced by the UK government in 2000. It requires 98% of patients to be discharged, transferred, or admitted to inpatient care within 4 hours of ...

Micro-seismic source location algorithm based on spatio-temporal distribution of arrival times

open access: yesMeikuang Anquan, 2023
In order to improve the precision of the micro-seismic hypocenter location and the robustness of algorithms, the objective function construction and spatiotemporal region information use of the location algorithm based on time are studied. The simulation

Determination of the arrival time of seismic signals based on the analysis of their phase characteristics [PDF]

open access: yesГеосистемы переходных зон
The article discusses methodological issues of applying phase characteristics in determining the arrival time of seismic waves. The accuracy of earthquake location depends on the precision with which the arrival times of longitudinal, transverse, and ...

Angle of arrival estimation for broadband signals : a comparison

open access: yes, 2013
This paper reviews and compares three different linear algebraic signal subspace techniques for angle of arrival estimation. These include a polynomial matrix approach to multiple signal classification (MUSIC), a parameterised spatial covariance matrix ...

Venous Thromboembolism in Pediatric Bone Sarcoma Patients: A 10‐Year, Single‐Institution Experience Encompassing the COVID‐19 Pandemic

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Osteosarcoma (OS) and Ewing sarcoma (EWS) are the most common primary bone cancers in children, but acute thrombosis is poorly characterized in this population. Our study evaluated the rates of venous thromboembolism (VTE) and associated risk factors in pediatric patients with bone sarcomas treated over a 10‐year period encompassing
