Interdisciplinary Materials, EarlyView.Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.

JCPP Advances, EarlyView.Our umbrella synthesis found strong, often equivalent, associations between child maltreatment and all examined mental health difficulties. Different types of maltreatment appear to have comparably negative effects on mental health. If replicated, these findings may cause us to reconsider conventional wisdom that suggests some forms of CM are less ...

WEAK GRAVITATIONAL LENSING BY STOCHASTIC GRAVITATIONAL WAVE BACKGROUND [PDF]
Publications of The Korean Astronomical Society, 2007 On the formulation frameworks of linearly perturbed spacetime and weak gravitational lensing(WGL) we studied the statistical properties of a bundle of light rays propagating through stochastic gravitational wave background(SGWB). For this we considered the SGWB as tensor perturbations of linearly perturbed Friedmann spacetime.

ВЛИЯНИЕ ГРАВИТАЦИОННОГО ЛИНЗИРОВАНИЯ НА ФУНКЦИЮ СВЕТИМОСТИ КВАЗАРОВ
Odessa Astronomical Publications, 2011 The function of quasar distribution on apparent brightness is discussed. This function is found on base of suggestion that quasars, at least partly, are strong gravitational lensing images of the active nuclei of distant galaxies.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Freeze–thaw processes cause periglacial creep (otherwise known as solifluction) which forms solifluction lobes. These are lobate features characterized by a steep riser (front) and a smooth tread (body). Despite the widespread occurrence of these lobes, the controls on their morphometry remain poorly understood. Research into solifluction lobe

Weak Gravitational Lensing—The Need for Surveys [PDF]
Symposium - International Astronomical Union, 1997 Light rays from distant sources are deflected if they pass near an intervening matter inhomogeneity. This gravitational lens effect is responsible for the well-established lens systems like multiple-imaged QSOs, (radio) ‘Einstein’ rings, the giant luminous arcs in clusters of galaxies, and the flux variations of stars in the LMC and the Galactic bulge ...

Precision Measurement of Large Shear Signals
The Astrophysical Journal LettersSo far, estimators of galaxy shape distortions are only carefully studied perturbatively in the case of small shear signals, mainly for weak-lensing science.

PLANTS, PEOPLE, PLANET, EarlyView.Xylella fastidiosa is a major plant pathogen affecting crops such as grapes, citrus, almonds, and olives, with potentially severe consequences for agricultural production and rural livelihoods worldwide. This paper examines the conflict around the management of the X. fastidiosa outbreak affecting olive trees in southern Italy.

Detecting gravitational lensing by matter currents
Astronomy & AstrophysicsWe explored the observational prospects for detecting gravitational lensing induced by cosmological matter currents, a relativistic correction to the standard density lensing effect arising from the motion of matter.
