G-D's Physics Revises the Universe's Cosmological & Astronomical "Time-Scaling"!

open access: yes, 2023
Abstract Twenty-First Century Theoretical Physics is undergoing a profound “Paradigmatic-Shift” from the Old “Material-Causal” Paradigm underlying General Relativity Theory (GRT) & Quantum Mechanics (QM) to the New “A-Causal Computation” “G-D’s Physics” (previously termed: “Computational Unified Field Theory”, CUFT)! This article presents empirical

Solid Harmonic Wavelet Bispectrum for Image Analysis

open access: yesAdvanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Website with interactive visualization of multivariate astronomical time series

open access: yes
International audienceLight curves represent astronomical time series of flux measured across one or more photometric bands. With the rapid growth of large-scale sky surveys, time-domain astronomy has become an essential area of modern astrophysical ...

Background-Source separation in astronomical images with Bayesian Probability Theory

open access: yes, 2010
In this work a new method for the detection of faint, both point-like and extended, astronomical objects based on the integrated treatment of source and background signals is described.

Liquid Metal Nanotransformers for Drug‐Resistant Pan‐Cancer Therapy in Patient‐Derived Organoids

open access: yesAdvanced Science, EarlyView.
Pan‐cancer therapies are severely limited in drug‐resistance patients due to genetic mutations and other factors, resulting in poor therapeutic outcomes and constrained clinical benefit. Liquid metal nanotransformers, a new class of shape‐transformable nanomaterials capable of dramatic morphological changes, offer a promising physical strategy to ...

Miocene magnetostratigraphy and cyclostratigraphy in the Mediterranean: extension of the astronomical polarity time scale

open access: yes, 1996
The first aim of this thesis was to extend the astronomical polarity time scale into the Miocene and to develop an integrated magnetostratigraphy and cyclostratigraphy for the middle to late Miocene marine record.

The ∼170 kyr astronomical cycle in the Early Permian Lucaogou Formation of the Junggar Basin

open access: yesFrontiers in Earth Science
According to Milankovitch’s theory, periodic climate change in Earth’s history is controlled by the periodic changes in the Earth’s orbit and axis of rotation. Milankovitch cycle include eccentricity, obliquity, and precession cycles. In addition to them,

Super-resolution reconstruction of astronomical images using time-scale adaptive normalized convolution

open access: yesChinese Journal of Aeronautics, 2018
Abstract In this work, we describe a new multiframe Super-Resolution (SR) framework based on time-scale adaptive Normalized Convolution (NC), and apply it to astronomical images. The method mainly uses the conceptual basis of NC where each neighborhood of a signal is expressed in terms of the corresponding subspace expanded by the chosen polynomial ...

Astronomical constraints on the cosmic evolution of the fine structure constant and possible quantum dimensions

open access: yes, 2000
We present measurements of absorption by the 21 cm hyperfine transition of neutral hydrogen toward radio sources at substantial look-back times. These data are used in combination with observations of rotational transitions of common interstellar ...

Study of Free‐Space Optical Quantum Network: Review and Prospectives

open access: yesAdvanced Science, EarlyView.
Free from the constraints of fiber connections, free‐space quantum network enables longer and more flexible quantum network connections. This review summarizes and comparatively analyzes free‐space quantum network experiments based on ground stations, satellites, and mobile platforms.
