Time-domain ptychography [PDF]
Physical Review A, 2015 Through dedicated measurements in the optical regime we demonstrate that ptychography can be applied to reconstruct complex-valued object functions that vary with time from a sequence of spectral measurements. A probe pulse of approximately 1 ps duration, time delayed in increments of 0.25 ps is shown to recover dynamics on a ten times faster time ...

Matrix Pencil Method for Vital Sign Detection from Signals Acquired by Microwave Sensors
Sensors, 2021 Microwave sensors have recently been introduced as high-temporal resolution sensors, which could be used in the contactless monitoring of artery pulsation and breathing. However, accurate and efficient signal processing methods are still required.

The Astrophysical Journal, 2023 The conditions under which accreting neutron stars launch radio-emitting jets and/or outflows are still poorly understood. The ultracompact X-ray binary X1850–087, located in the globular cluster NGC 6712, is a persistent atoll-type X-ray source that has

Optomechanical time-domain reflectometry [PDF]
Nature Communications, 2018 AbstractOptical fibres constitute an exceptional sensing platform. However, standard fibres present an inherent sensing challenge: they confine light to an inner core. Consequently, distributed fibre sensors are restricted to the measurement of conditions that prevail within the core. This work presents distributed analysis of media outside unmodified,

Identifying the best method for linearizing the nonlinear friction term to analyze the transient flow in pipeline systems [PDF]
Journal of Applied Research in Water and Wastewater, 2022 To analyze transient flows, continuity and momentum equations must be solved. Due to the non-linear friction term in the momentum equation, numerical methods such as method of characteristics (MOC) are used to analyze the problem in thetime domain ...

Is the M81 Fast Radio Burst Host Globular Cluster Special?
The Astrophysical Journal Letters, 2023 We use multiband archival Hubble Space Telescope (HST) observations to measure the photometric and structural parameters of the M81 globular cluster (GC) that hosts the fast radio burst FRB 20200120E. Our best-fitting King model has an effective radius r

Microwave Angiography by Ultra-Wideband Sounding: A Preliminary Investigation
Diagnostics, 2023 Angiography is a very informative method for physicians such as cardiologists, neurologists and neuroscientists. The current modalities experience some shortages, e.g., ultrasound is very operator dependent.
