Integrating multimodal data and machine learning for entrepreneurship research
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary Extant research in neuroscience suggests that human perception is multimodal in nature—we model the world integrating diverse data sources such as sound, images, taste, and smell. Working in a dynamic environment, entrepreneurs are expected to draw on multimodal inputs in their decision making.

Cosmography of the Dynamical Cosmological «Constant»
East European Journal of Physics, 2019 The paper considers a cosmographical approach to analyze cosmological models. Cosmography is a method to describe the kinematics of the cosmological expansion based only on the cosmological principle. We consider a method of treating free parameters of a

Unimodular Approaches to the Cosmological Constant Problem
Universe, 2023 We review selected aspects of unimodular gravity and we discuss its viability as a solution of the old cosmological constant problem. In unimodular gravity, the cosmological constant is promoted to a global degree of freedom.

Gravity in spacetimes with cosmological constants [PDF]
, 2009 This thesis is composed of two parts: gravity in the spacetime with a negative/positive cosmological constant. The first part, which is the negative case, devotes to constructing the IIB supergravity dual solution in AdS/CFT correspondence for N = (1, 0)

Cosmological constant, fine structure constant and beyond [PDF]
, 2017 In the present work, we consider the cosmological constant model $$\Lambda \propto \alpha ^{-6}$$, which is well motivated from three independent approaches. As is well known, the hint of varying fine structure constant $$\alpha $$ was found in 1998. If $

When Thriving for More Collapses the System: The Academic Reproduction of Uncaring Structures
British Journal of Management, EarlyView.Abstract This essay argues that the widening gap between aspirational aims and visionary orientations and the prevailing practices in neoliberal academia stems from deeper, historically rooted, market‐based logics shaping our institutions, increasingly governed by economic values and academic subjectivities therein.

REMARKS ON THE COSMOLOGICAL CONSTANT [PDF]
Modern Physics Letters A, 2013 The acceleration of the surface of last scatter (SLS) must somehow reflect the energy content within it. A test particle at the SLS is assumed to experience a linear combination of two forces: one Newtonian, the other pseudo-Newtonian describable by a cosmological constant Λ in general relativity.

Geodesic equations in black hole space-times with cosmological constant [PDF]
, 2010 The physics of a gravitational field can be explored by studying the geodesic motion of test particles and light. Although the majority of gravitational effects can be discussed using approximations and numerics, a systematic study of all effects can ...

Bulk viscous cosmological models with a cosmological constant: Observational constraints
Astronomy & AstrophysicsAims. We investigate whether viscous cold dark matter (vCDM) in a Λ-dominated Friedmann-Lemaître-Robertson-Walker (FLRW) universe can alleviate the Hubble tension, while satisfying thermodynamic constraints.
