Executive Function and Entrepreneurial Opportunity Exploitation Under Risk and Uncertainty

Strategic Change, EarlyView.
ABSTRACT This study examines how executive functions shape entrepreneurial opportunity exploitation under different knowledge environments. Drawing on Knight's distinction between risk and uncertainty, we conducted a vignette experiment with 200 working adults.

Periodontal microbiology and microbial etiology of periodontal diseases: Historical concepts and contemporary perspectives

Periodontology 2000, EarlyView., 2023
Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

Dark Matter Distinguished by Skewed Microlensing in the “Dragon Arc”

The Astrophysical Journal Letters
Many microlensed stars discovered by JWST closely follow the winding critical curve of A370 along the “Dragon Arc” with m _AB  > 26.5, which we show comprises asymptotic giant branch stars microlensed by the observed level of diffuse cluster stars ...

Navigating the Twin Transformation: How Digitalization and Sustainability Shape the Future

Strategic Change, EarlyView.
ABSTRACT Amid growing societal and scholarly interest in the interplay between sustainability transformation (ST) and digital transformation (DT), this study conducts a systematic literature review to advance the understanding of twin transformation (TT). Analyzing 65 peer‐reviewed articles, this review makes three key contributions: (1) It synthesizes

Intuition–Driven Prospection and Uncertainty Misalignment: Sources of Entrepreneurial Agency Problems in Ventures

Strategic Change, EarlyView.
ABSTRACT Start‐up CEOs are usually more aligned with the interests of the venture board compared to CEOs in legacy firms, and therefore it is usual to conclude that the traditional agency problem is lower in ventures. In this article, it is argued that this is only half of the story, and that the agency problem is reversed in early ventures such that ...

Gravitational Lensing by Spherical Lenses

International Journal of Astronomy and Astrophysics, 2014
In this work we introduced a new proposal to study the gravitational lensing theory by spherical lenses, starting from its surface mass density $ (x)$ written in terms of a decreasing function $f$ of a dimensionless coordinate $x$ on the lens plane.

Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy

Nano Select, EarlyView.
Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...

Generating Dark Matter Subhalo Populations Using Normalizing Flows

The Open Journal of Astrophysics
Strong gravitational lensing is a powerful tool for probing the nature of dark matter, as lensing signals are sensitive to the dark matter substructure within the lensing galaxy.

Search for strong gravitational lensing effect in the current GRB data of BATSE

, 2014
Because gamma-ray bursts (GRBs) trace the high-z Universe, there is an appreciable probability for a GRB to be gravitational lensed by galaxies in the universe.

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 ...
