Time-of-arrival in quantum mechanics [PDF]

, 1996
We study the problem of computing the probability for the time-of-arrival of a quantum particle at a given spatial position. We consider a solution to this problem based on the spectral decomposition of the particle's (Heisenberg) state into the ...

Distortions of Experimental Muon Arrival Time Distributions of Extensive Air Showers by the Observation Conditions [PDF]

, 2001
Event-by-event measured arrival time distributions of Extensive Air Shower (EAS) muons are affected and distorted by various interrelated effects which originate from the time resolution of the timing detectors, from fluctuations of the reference time ...

Times of arrival: Bohm beats Kijowski

, 2005
We prove that the Bohmian arrival time of the 1D Schroedinger evolution violates the quadratic form structure on which Kijowski's axiomatic treatment of arrival times is based. Within Kijowski's framework, for a free right moving wave packet, the various

Time of Arrival from Bohmian Flow [PDF]

, 2002
We develop a new conception for the quantum mechanical arrival time distribution from the perspective of Bohmian mechanics. A detection probability for detectors sensitive to quite arbitrary spacetime domains is formulated.

Significantly Earlier Spring Migration in Most Bird Species at the Eastern Limit of Europe

Animals, 2023
The first arrival dates of 31 species of migrant birds in the Tatarstan Republic of Russia were monitored for the 34-year period from 1989–2022. Trends in first arrival date were evaluated using regression against the year value. Patterns in arrival data

The Role of Arrival Areas for Migrant Integration and Resource Access

Urban Planning, 2020
Research on socio-economically disadvantaged neighbourhoods with high numbers of migrants tends to problematise such areas as hindering upward social mobility and further enhancing disadvantage.

Mind the Gap – Passenger Arrival Patterns in Multi-agent Simulations [PDF]

, 2016
In most studies mathematical models are developed finding the expected waiting time to be a function of the headway. These models have in common that the proportion of passengers that arrive randomly at a public transport stop is less as headway in ...
