Statistical Investigations of the Radial Interplanetary Magnetic Field Component Impact on the Magnetotail Current Sheet Structure of Mars: MAVEN Observations

The Astrophysical Journal
In this study, we investigated the role of interplanetary magnetic field (IMF) orientation in controlling the location and structure of the current sheet (CS) in the Martian magnetotail.

An Optimized VMD Method for Predicting Milling Cutter Wear Using Vibration Signal

Machines, 2022
Tool wear has a negative impact on machining quality and efficiency. As for the nonlinear and non-stationary characteristics of vibration signals and strong background noises during the milling process, an identification method of the milling cutter wear

Simulating a metallicity-dependent initial mass function: Consequences for feedback and chemical abundances

, 2018
Observational and theoretical arguments increasingly suggest that the initial mass function (IMF) of stars may depend systematically on environment, yet most galaxy formation models to date assume a universal IMF.

Lower mass normalization of the stellar initial mass function for dense massive early-type galaxies at z ~ 1.4 [PDF]

, 2014
This paper aims at understanding if the normalization of the stellar initial mass function (IMF) of massive early-type galaxies (ETGs) varies with cosmic time and/or with mean stellar mass density Sigma (M*/2\pi Re^2).

National Environmental Policies and Corporate Green Innovation: The Mirroring Versus Substitution Hypotheses

Business Strategy and the Environment, EarlyView.
ABSTRACT Drawing on comparative institutional theory, we study the nature and magnitude of the effects of national environmental policies on corporate green innovation in developed versus emerging markets. Using a sample of 1831 listed firms in 34 countries from 2002 to 2020, we find that national environmental policies increase corporate green ...

The IMF of Extremely Metal-Poor Stars and the Probe into the Star-Formation Process of the Milky Way

, 2007
We discuss the star formation history of the Galaxy, based on the observations of extremely metal-poor stars (EMP) in the Galactic halo, to gain an insight into the evolution and structure formation in the early universe.

ALMA-IMF

Astronomy & Astrophysics, 2023
Context.Among the most central open questions regarding the initial mass function (IMF) of stars is the impact of environment on the shape of the core mass function (CMF) and thus potentially on the IMF.Aims.The ALMA-IMF Large Program aims to investigate the variations in the core distributions (CMF and mass segregation) with cloud characteristics ...

Environmental, Social, and Governance Factors as Tools for Improving Market Efficiency: A Study on Equity Misvaluation

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigated whether superior environmental, social, and governance (ESG) practices enhance corporate value and market efficiency under various economic theories. Using a multi‐country panel of 31 economies from 2015 to 2022, we find that both ESG performance and disclosure improve intrinsic value and mitigate equity misvaluation ...

The Influence of Interplanetary Magnetic Field Orientations on the Martian Bow Shock and Magnetosheath Magnetic Field

The Astrophysical Journal
Unlike Earth, Mars lacks a global intrinsic magnetic field but has regional crustal magnetic fields concentrated in its southern hemisphere. This unique configuration leads to distinctive interactions with the solar wind.

Constraints on a Universal IMF from UV to Near-IR Galaxy Luminosity Densities

, 2003
We obtain constraints on the slope of a universal stellar initial mass function (IMF) over a range of cosmic star-formation histories (SFH) using z=0.1 luminosity densities in the range from 0.2 to 2.2 microns.
