Forecasting the Volatility of Australian Stock Returns: Do Common Factors Help? [PDF]

This paper develops univariate and multivariate forecasting models for realized volatility in Australian stocks. We consider multivariate models with common features or common factors, and we suggest estimation procedures for approximate factor models ...

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Association Between Motor Pathway Damage and Motor Deficit in Upper and Lower Limb in People With MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Corticospinal tract damage is common in people with MS, but the degree of clinical symptoms varies. We hypothesize that corticospinal tract lesions are more extensive and severe in people with MS with motor impairments in both upper and lower limbs.

Accurate Yield Curve Scenarios Generation using Functional Gradient Descent [PDF]

We propose a multivariate nonparametric technique for generating reliable historical yield curve scenarios and confidence intervals. The approach is based on a Functional Gradient Descent (FGD) estimation of the conditional mean vector and volatility ...

Spatial and Volumetric Characteristics of Glioblastoma: Associations With Clinical Presentation and Survival

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We aim to comprehensively analyze how regional tumor and edema characteristics are associated with clinical presentations and survival outcomes in a large cohort of glioblastoma patients. Methods Patients with IDH‐wildtype glioblastoma who received brain MRI from 2010 to 2023 were included.

Assimilating leaf area index and soil moisture into the WOFOST model for improved maize (Zea mays L.) yield estimation in Ethiopia

International Journal of Applied Earth Observations and Geoinformation
Recently, integrating earth observation (EO) data and crop growth models (CGMs), has been widely applied to improve the accuracy of crop yield estimation.

Response to Allopurinol and Febuxostat According to the Fractional Excretion of Urate in Men With Gout

Arthritis Care &Research, EarlyView.
Objective Body mass index (BMI), glomerular filtration rate (GFR), and pretreatment urate levels have been reported to influence the urate‐lowering response to allopurinol. We investigated whether the fractional excretion of uric acid (FEUA) also modulates this response and relates to oxypurinol concentrations.

Estimate of the flash-point of petroleum using a multivariate analysis.

BUNSEKI KAGAKU, 2001
従来から行われているJISによる石油類の引火点の測定は, 試料量を1回に50ml必要とし, 予期引火点を基に行っている. しかし, 法科学試料では試料量が少量であったり, 予期引火点などの情報はほとんど得られないことから, 引火点の測定が不可能であったり, 試料を浪費する場合もある. 一般に, 石油系液体の検査の場合には, まずガスクロマトグラフィー (GC) により試料の種類などを確認するため, GCの結果から引火点の推定が可能ならば, 少量の試料量で引火点の情報を得ることができる. 更にその温度を予期引火点としてJISによる測定を行うことが可能となり, 測定時間が短縮でき試料が最少量で測定できると考えられる.
