Bloom compression alongside marine heatwaves contemporary with the Oregon upwelling season

Limnology and Oceanography, EarlyView.
Abstract Marine heatwave (MHW) events have led to acute decreases in primary production and phytoplankton biomass in the surface ocean, particularly at the mid latitudes. In the Northeast Pacific, these anomalous events have occasionally encroached onto the Oregon shelf during the ecologically important summer upwelling season.

Inferring Properties of Dark Galactic Halos Using Strongly Lensed Gravitational Waves

The Astrophysical Journal
Gravitational waves (GWs) can be deflected, similarly to electromagnetic (EM) waves, by massive objects through the phenomenon of gravitational lensing .

Pulsed Laser Ablation in Liquid: Numerical Evaluation of Laser Fluence

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
Pulsed laser ablation in liquid is a very powerful technique that allows to synthesize colloidal solution of nanoparticles (NPs) without waste. Herein, a computational approach that given the experimental parameters and draws the laser ray paths inside the experimental apparatus is developed, the effective fluence on the target surface is evaluated ...

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.

Strong deflection gravitational lensing

, 2012
In this work are reviewed several aspects of gravitational lensing produced by astrophysical bodies that strongly curve the spacetime in their vicinity. When an object with a photon sphere (e.g. a black hole) is interposed between a source and an observer, in addition to primary and secondary images due to small deflections of the light rays, there are

A dearth of dark matter in strong gravitational lenses [PDF]

Monthly Notices of the Royal Astronomical Society, 2014
I show that the lensing masses of the SLACS sample of strong gravitational lenses are consistent with the stellar masses determined from population synthesis models using the Salpeter IMF. This is true in the context of both General Relativity and modified Newtonian dynamics, and is in agreement with the expectation of MOND that there should be little ...

Understanding the Limited Uptake of Reprocessed Construction Materials: A Pro‐Environmental Behaviour Perspective

Sustainable Development, EarlyView.
ABSTRACT Reverse logistics (RL) aims to direct demolition waste (DW) away from landfills towards alternative uses by converting it into reprocessed construction materials (RCMs). However, recent studies indicate that the uptake of RCMs remains limited, adversely affecting the effectiveness of RL for DW. Therefore, developing markets for these materials

Surface‐Sensitive Fractioning of Flowing Colloidal Suspensions Sedimented at a Photochemically Active Wall

Small, EarlyView.
A straightforward technique for fractionating sedimented, same‐sized colloidal particles based on small differences in their surface properties is described. This microfluidic technology method exploits the velocity differentials within a shear‐flow via inducing a phoretic lift above the bottom porous polymer interface that is capable of light‐induced ...

Model-independent H0 within FLRW: Joint Constraints from GWTC-3 Standard Sirens and Strong Lensing Time Delays

The Astrophysical Journal Letters
We use 47 gravitational-wave (GW) standard sirens from the third Gravitational-Wave Transient Catalog to calibrate distances in the strong gravitational lensing (SGL) system RXJ1131-1231 and constrain the Hubble constant ( H _0 ) via the distance sum ...

Racket sociality: investigating intimidation in North India

Journal of the Royal Anthropological Institute, EarlyView.
This article is an ethnographic investigation into acts of intimidation and threats. Theoretically, it dialogues with ‘racket’ – a key analytical term in the sociology of domination, state‐making, and mafias. The anthropology of power, violence, and crime has paid scant attention to the morphology of threats and the ways interpersonal intimidation ...
