Theory of Ternary Jitter-Based True Random Number Generators Composed of Identical Gates

, 2017
In this paper, we continue to study of a novel family of generators producing true uniform random numbers. The generator consists of a number of identical ternary logic combinational gates.

DynaTOF: Time‐Resolved Noncontrast Cerebral MR Angiography Using Spatially Modulated RF Saturation

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1134-1147, September 2026.
ABSTRACT Purpose To develop a time‐resolved extension of three‐dimensional time‐of‐flight MR angiography, termed Dynamic TOF (DynaTOF), that exploits intrinsic RF saturation behavior to enable noncontrast visualization of cerebrovascular hemodynamics.

Intra‐MRI Head Motion Tracking and Correction: A Quantitative In Vivo Evaluation Framework

NMR in Biomedicine, Volume 39, Issue 9, September 2026.
This framework introduces, for the first time, an in vivo quantification of intra‐MRI head tracking accuracy and precision. By comparing a markerless optical system (MOS) and fat‐signal navigators (FatNav) against a rigid registration‐based reference standard, it successfully detects subtle, axis‐specific performance differences and strengths between ...

Pulse retiming based on XPM using parabolic pulses formed in a fiber Bragg grating [PDF]

, 2006
We experimentally demonstrate a novel all-optical all-fiberized pulse retiming scheme incorporating parabolic pulses generated in a linear fashion through pulse shaping in a superstructured fiber Bragg grating. The scheme relies on chirping the signal to

Squeezed‐State Semi‐Device‐Independent Quantum Randomness Generation

Advanced Quantum Technologies, Volume 9, Issue 9, September 2026.
Semi‐device‐independent quantum randomness is certified for squeezed‐coherent binary states using only their trusted overlap and the observed homodyne error. Including the deterministic extremes of the full binary‐qubit POVM gives the correct closed‐form Shannon rate.

Robust Short‐Term Forecasting of Thermospheric Density and Orbit Prediction Using an Interpretable iTransformer Model

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Accurate short‐term forecasting of thermospheric mass density is crucial for satellite operations. However, achieving high‐precision predictions remains a significant challenge. In this study, we develop an iTransformer framework that forecasts thermospheric density over the next 24 hr using observations from the preceding 24 hr. Using density

Random jitter extraction technique in a multi-gigahertz signal

, 2004
In this paper, we propose a simple technique for estimating the standard deviation of a Gaussian random jitter component in a multi-gigahertz signal. This method may utilize existing on-chip single-shot period measurement techniques to measure the multi ...

Electrophysiological Correlates of Encoding Indicate Altered Processing but Comparable Subsequent Memory Effects Across Virtual Reality and Desktop‐Based Conditions

European Journal of Neuroscience, Volume 64, Issue 5, September 2026.
The study examined whether successful object encoding relies on comparable or modality‐specific neural processes across immersive virtual reality (VR) and desktop (PC) presentation. Encoding‐related EEG activity was analyzed in a subsequent memory paradigm using ERP and oscillatory markers.

An experimentally informed computational model of neurovestibular adaptation to altered gravity

Experimental Physiology, Volume 111, Issue 9, Page 4195-4208, 1 September 2026.
Abstract Transitions to altered gravity environments result in acute sensorimotor impairment for astronauts, leading to serious mission and safety risks in the crucial first moments in a new setting. Our understanding of the time course and severity of impairment in the early stages of adaptation remains limited and confounded by unmonitored head ...

Flame flutter due to g-jitter

, 2019
We consider a laminar diffusion flame as a result of reaction between methane and oxygen, which enter our computational domain from an inner and annular region, respectively.We have added a (sinusoidal) time-dependent source term, signifying 'g-jitter ...
