Phase Shifts in Stochastic Resonance [PDF]

open access: yesPhysical Review Letters, 1992
The response of an overdamped bistable system to a periodic force is investigated using linear-response theory and by analog electronic experiment. It is shown, both theoretically and experimentally that a phase lag phi exists between the force and the response, and that |phi| passes through a maximum when the noise intensity is tuned through the range

Synchronous Phase Shift at LHC

open access: yes, 2013
The electron cloud in vacuum pipes of accelerators of positively charged particle beams causes a beam energy loss which could be estimated from the synchronous phase.

Performance of Equal Phase-Shift Search for One Iteration

open access: yes, 2007
Grover presented the phase-shift search by replacing the selective inversions by selective phase shifts of $\pi /3$. In this paper, we investigate the phase-shift search with general equal phase shifts.

Design of a Branch-line Microstrip Coupler Using Spirals and Step Impedance Cells for WiMAX Applications

open access: yesARO-The Scientific Journal of Koya University, 2020
branch-line microstrip coupler is designed and fabricated in this paper. The proposed coupler operates at 3 GHz, which is suitable for WiMAX applications.

High SNR BER Comparison of Coherent and Differentially Coherent Modulation Schemes in Lognormal Fading Channels

open access: yes, 2014
Using an auxiliary random variable technique, we prove that binary differential phase-shift keying and binary phase-shift keying have the same asymptotic bit-error rate performance in lognormal fading channels.

Phase-shift calculation using continuum-discretized states [PDF]

open access: yes, 2008
We present a method for calculating scattering phase shifts which utilizes continuum-discretized states obtained in a bound-state type calculation.

Light sets the brain’s daily clock by regional quickening and slowing of the molecular clockworks at dawn and dusk

open access: yeseLife, 2021
How daily clocks in the brain are set by light to local environmental time and encode the seasons is not fully understood. The suprachiasmatic nucleus (SCN) is a central circadian clock in mammals that orchestrates physiology and behavior in tune with ...

Momentum Dependence of Phase Shifts [PDF]

open access: yesPhysical Review, 1955
A lower limit is found for the momentum derivative of the scattering phase shifts of a relativistic neutral two-particle system when the interaction is of finite range.

Four-phase differential phase shift resolver [PDF]

open access: yes, 1973
Two systems have been developed to resolve phase uncertainty without transmitting reference signals. In both methods signal is impressed on carrier as differential, rather than absolute, phase shift.

Stereotactic Body Radiation Therapy for Pediatric, Adolescent, and Young Adult Patients With Osteosarcoma: Local Control Outcomes With Dosimetric Analysis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Osteosarcoma is a radioresistant tumor that may benefit from stereotactic body radiation therapy (SBRT) for locoregional control in metastatic/recurrent disease. We report institutional practice patterns, outcomes, toxicity, and failures in osteosarcoma patients treated with SBRT.
