Family Firms' Boards: Reflections Based on Theoretical Groundings

Strategic Change, EarlyView.
ABSTRACT Boards of Directors is one of the most recurring topics in corporate governance literature. In the family firm realm, Boards of Directors have distinctive features compared to non‐family firms; their functions and activities can differ significantly.

Quasar Milli-lensing and Cold Dark Matter (TNG50) Subhaloes. I. Image Splitting

The Astrophysical Journal
We use numerical mass density profiles from the TNG50 simulation to study the impact of gravitational milli-lensing by dark matter subhaloes on the images of lensed quasars.

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.

Revealing dark matter dress of primordial black holes by cosmological lensing

Physics Letters B, 2023
Stellar-mass primordial black holes (PBHs) from the early Universe can directly contribute to the gravitational wave (GW) events observed by LIGO, but can only comprise a subdominant component of the dark matter (DM).

Generation of Oil‐In‐Water Emulsion‐Core Sodium Alginate Beads

Macromolecular Chemistry and Physics, EarlyView.
A core‐shell encapsulation platform is developed by embedding oil‐in‐water emulsions within alginate shells. Optimized formulations with mineral oil, CMC, and non‐ionic surfactants produce uniform spherical beads with tunable core sizes and shell thicknesses.

Cosmological applications of gravitational lensing [PDF]

Symposium - International Astronomical Union, 1996
It was recognized very early that the gravitational lens effect can be used as an efficient cosmological tool. Of the many researchers who foresaw the use of lensing, F. Zwicky and S. Refsdal should be explicitly mentioned. The perhaps most accurate predictions and foresights by these two authors are as follows: Zwicky estimated the probability that a ...

Enhancing Conductivity and Mechanical Properties in Epoxy Composites Through Generating Percolated Structures Using Novel Acoustic Pre‐Mixing Method

Journal of Polymer Science, EarlyView.
Utilization of resonance acoustic (pre) mixing of nanoparticles with epoxy resin resulting in synergistic percolated hybrid epoxy nanocomposite. ABSTRACT Advanced engineered materials are being used to explore and exploit harsh environments, requiring improvement in composite materials.

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 ...

μ-GLANCE: A Novel Technique to Detect Chromatically and Achromatically Lensed Gravitational-wave Signals

The Astrophysical Journal
Gravitational microlensing in the wave-optics (WO) regime occurs when the Schwarzschild radius of a lensing object is comparable to or smaller than the wavelength of incoming gravitational waves (GWs), producing chromatic amplitude and phase modulations.

Variability of gravitational lens images, caused by variability of gravitational field of lens: binary systems and loops of cosmic strings

Вісник Астрономічної школи, 2003
Gravitational lenses with changeable mass distribution cause characteristic changes of image brightness. Detection and analyze of such changes allow us to clarify the nature of the lens. This effect gives a possibility to obtain such dynamical objects as
