1 Introduction In 1982, Magerl [1] first reported the use of percutaneous pedicle screw fixation (PPSF) technique in thoracolumbar spine, which had the advantages of small incision, less blood loss and minimal damage to the muscles in the lower back [2]. Since then, percutaneous pedicle screw fixation has been gradually applied in clinical practice. Foley et al.

Junko Koeda and Bin WeiWorking Paper 2024-8September 2024Full text Abstract:This study evaluates the effectiveness of Japan's unconventional monetary policies over the past quarter century within a unified term structure framework. It specifically examines the impact of the Bank of Japan's (BOJ) outcome-based forward guidance and yield curve control (YCC) and incorporates other policy types into the framework.

AbstractThermoelectrics converting heat and electricity directly attract broad attentions. To enhance the thermoelectric figure of merit, zT, one of the key points is to decouple the carrier-phonon transport. Here, we propose an entropy engineering strategy to realize the carrier-phonon decoupling in the typical SrTiO3-based perovskite thermoelectrics. By high-entropy design, the lattice thermal conductivity could be reduced nearly to the amorphous limit, 1.25 W m−1 K−1.

Full text Summary:This article analyzes the effectiveness of the Secondary Market Corporate Credit Facility (SMCCF) in stabilizing the US corporate bond market during the COVID-19 pandemic. The SMCCF announcements in March and April 2020 significantly reduced credit spreads across different bond maturities, restoring a more typical upward-sloping yield curve.

A comprehensive understanding of phonon transport is essential to develop effective solutions for heat dissipation. Gallium nitride (GaN), a representative of third-generation power semiconductors, has been extensively studied regarding its thermodynamics and lattice dynamics. However, the temperature-dependent phonon properties, especially the anharmonicity at high temperatures, are poorly understood.

AbstractMacroautophagy is a process that cells engulf cytosolic materials by autophagosomes and deliver them to lysosomes for degradation. The biogenesis of autophagosomes requires ATG2 as a lipid transfer protein to transport lipids from existing membranes to phagophores. It is generally believed that endoplasmic reticulum is the main source for lipid supply of the forming autophagosomes; whether ATG2 can transfer lipids from other organelles to phagophores remains elusive.

Junko Koeda and Bin WeiWorking Paper 2023-16October 2023Full text Abstract:Forward guidance provides monetary policy communication for an economy at the effective lower bound (ELB). In this paper, we consider both calendar- and outcome-based forward guidance about the timing of liftoff. We develop a novel macro-finance shadow rate term structure model by introducing unspanned macro factors and an outcome-based liftoff condition.

1. IntroductionThe study of synchronization initially started with Christiaan Huygens’ coupled pendulums; since then, different topics related to synchronization have been raised [1,2,3,4,5,6]. For example, the stability of a particular synchronization state is studied in [7,8,9] through looking at the eigenvalues of the Jacobian matrix of the linearized system; the question “is it stable once they get sync” is addressed—i.e., whether the incoherent state of coupled oscillators is stable or not.

AbstractPolyhedral distortion, associated closely with the atomic arrangement and interatomic interactions, drives many unique behaviors in solids, such as phase transition and negative thermal expansion. In thermoelectric heteroanionic oxides, the anionic polyhedra are widely present, but their effect on thermal transport is rarely investigated.

AbstractRelaxor ferroelectrics are the primary candidates for high-performance energy storage dielectric capacitors. A common approach to tuning the relaxor properties is to regulate the local compositional inhomogeneity, but there is a lack of a quantitative evaluation way for compositional fluctuation in relaxors. Here we propose configurational entropy as an index for the quantitative evaluation of local compositional inhomogeneity.
