Managing House Price Booms: Evolution of IMF Surveillance and Policy Advice [PDF]

, 2019
AbstractThis chapter describes the evolution of IMF monitoring—“surveillance” in the IMF’s jargon—of housing markets from 2008 to the present. It explains how the IMF has assessed overvaluation in housing markets and the advice offered on the policy tools needed to manage house price booms.

The Chemical Evolution of the Galaxy with Variable IMFs

, 1999
In this work we explore the effects of adopting initial mass functions (IMFs) variable in time on the chemical evolution of the Galaxy. In order to do that we adopt a chemical evolution model which assumes two main infall episodes for the formation of the Galaxy and which proved to be successful in reproducing the majority of the observational ...

Population III.1 stars: formation, feedback and evolution of the IMF [PDF]

Proceedings of the International Astronomical Union, 2008
AbstractI discuss current theoretical expectations of how primordial, Pop III.1 stars form. Lack of direct observational constraints makes this a challenging task. In particular predicting the mass of these stars requires solving a series of problems, which all affect, perhaps drastically, the final outcome.

Evolution of IMF By induced asymmetries during substorms: Superposed epoch analysis at geosynchronous orbit

Frontiers in Astronomy and Space Sciences, 2022
The By component of the magnetic field inside the magnetosphere is positively correlated with the By component of the Interplanetary Magnetic Field (IMF). This leads to asymmetries in aurora, plasma convection and electric currents between the northern and southern hemispheres It has been demonstrated that magnetic conjugate locations in the northern ...

Characteristics of multiple transpolar arcs motion and its corresponding magnetospheric dynamic process

Frontiers in Astronomy and Space Sciences
Multiple Transpolar arcs (MTPAs) are distinct auroral phenomenon occurring in the high-latitude ionosphere under prolonged northward interplanetary magnetic field (IMF) conditions. While the evolution of MTPAs is thought to be mainly modulated by the IMF

Polar, Cluster and SuperDARN evidence for high-latitude merging during southward IMF: temporal/spatial evolution [PDF]

Annales Geophysicae, 2003
Abstract. Magnetic merging on the dayside magnetopause often occurs at high latitudes. Polar measured fluxes of accelerated ions and wave Poynting vectors while skimming the subsolar magnetopause. The measurements indicate that their source was located to the north of the spacecraft, well removed from expected component merging sites.

Restriction of Individual Branched‐Chain Amino Acids has Distinct Effects on the Development and Progression of Alzheimer's Disease in 3xTg Mice

Advanced Science, EarlyView.
Protein restriction (PR) slows Alzheimer's disease (AD) in mice, and other benefits of PR are due to decreased branched‐chain amino acids (BCAAs). We show that restricting any BCAA has benefits, with sex‐ and BCAA‐specific impacts on pathology, molecular signaling, and cognition.

Poleward moving auroral forms (PMAFs) revisited: responses of aurorae, plasma convection and Birkeland currents in the pre- and postnoon sectors under positive and negative IMF B_y conditions [PDF]

Annales Geophysicae, 2007
Using five case studies, we investigate the dynamical evolution of dayside auroral precipitation in relation to plasma convection, classifying it by the IMF By component and position with respect to noon. Auroral observations were made by meridian

An Integrated Picture of Star Formation, Metallicity Evolution, and Galactic Stellar Mass Assembly

, 2008
We present an integrated study of star formation and galactic stellar mass assembly from z=0.05-1.5 and galactic metallicity evolution from z=0.05-0.9 using a very large and highly spectroscopically complete sample selected by rest-frame NIR bolometric ...

A Possible Solution for the $M/L-\mathrm{[Fe/H]}$ Relation of Globular Clusters in M31. II. the Age-Metallicity Relation [PDF]

, 2017
This is the second of a series of papers in which we present a new solution to reconcile the prediction of single stellar population (SSP) models with the observed stellar mass-to-light ($M/L$) ratios of globular clusters (GCs) in M31 and its trend with ...
