Time of Arrival from Bohmian Flow [PDF]
Journal of Physics A: Mathematical and General, 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.

Physical Review A, 1998 Although one can show formally that a time-of-arrival operator cannot exist, one can modify the low momentum behaviour of the operator slightly so that it is self-adjoint.

Differentiability of the arrival time [PDF]
Communications on Pure and Applied Mathematics, 2015 For a monotonically advancing front, the arrival time is the time when the front reaches a given point. We show that it is twice differentiable everywhere with uniformly bounded second derivative.

Time-of-arrival in quantum mechanics [PDF]
Physical Review A, 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 ...

Contrast-Enhanced Ultrasound in Distinguishing between Malignant and Benign Peripheral Pulmonary Consolidations: The Debated Utility of the Contrast Enhancement Arrival Time [PDF]
Diagnostics, 2023 Background. Limited studies and observations conducted on a too small number of patients prevent determining the actual clinical utility of pulmonary contrast-enhanced ultrasound (CEUS).

State-Space Model for Arrival Time Simulations and Methodology for Offline Blade Tip-Timing Software Characterization [PDF]
Sensors, 2023 Blade tip-timing is an extensively used technique for measuring blade vibrations in turbine and compressor stages; it is one of the preferred techniques used for characterizing their dynamic behaviors using non-contact probes.

Confined Quantum Time of Arrivals [PDF]
Physical Review Letters, 2005 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.
