Causal correlations between inflammatory proteins and heart failure: A two‐sample Mendelian randomization analysis

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1374-1385, April 2025.
Abstract Aims Inflammation plays a critical role in both the development and progression of heart failure (HF), which is a leading cause of morbidity and mortality worldwide. However, the causality between specific inflammation‐related proteins and HF risk remains unclear.

A Multi-Scan Labeled Random Finite Set Model for Multi-object State Estimation

open access: yes, 2018
State space models in which the system state is a finite set--called the multi-object state--have generated considerable interest in recent years. Smoothing for state space models provides better estimation performance than filtering by using the full ...

Simple Recursion Relations for General Field Theories [PDF]

open access: yes, 2015
On-shell methods offer an alternative definition of quantum field theory at tree-level, replacing Feynman diagrams with recursion relations and interaction vertices with a handful of seed scattering amplitudes.

All-order celestial OPE from on-shell recursion

open access: yesJournal of High Energy Physics, 2023
We determine tree level, all-order celestial operator product expansions (OPEs) of gluons and gravitons in the maximally helicity violating (MHV) sector.

A strange recursion operator for a new integrable system of coupled Korteweg - de Vries equations

open access: yes, 2002
A recursion operator is constructed for a new integrable system of coupled Korteweg - de Vries equations by the method of gauge-invariant description of zero-curvature representations.

Forecasting With Dynamic Factor Models Estimated by Partial Least Squares

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Dynamic factor models (DFMs) have found great success in nowcasting and short‐term macroeconomic forecasting when incorporating large sets of predictive information. The factor loadings are typically estimated cross‐sectionally with principal component analysis (PCA) or maximum likelihood (ML), which ignore whether the factors have predictive ...

Industry Portfolio Volatility Connections and Industry Portfolio Returns

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This paper tracks dynamic connections that form among daily US industry portfolio return volatilities using a Bayesian time‐varying parameter VAR model. Market participants often focus on sectors to filter vast amounts of information, and this focus results in cross‐industry return predictability. We characterise connections that form over the

A Survey on Teaching and Learning Recursive Programming

open access: yesInformatics in Education, 2014
We survey the literature about the teaching and learning of recursive programming. After a short history of the advent of recursion in programming languages and its adoption by programmers, we present curricular approaches to recursion, including a ...

The Recursion operators of the BKP hierarchy and the CKP Hierarchy

open access: yes, 2012
In this paper, under the constraints of the BKP(CKP) hierarchy, a crucial observation is that the odd dynamical variable $u_{2k+1}$ can be explicitly expressed by the even dynamical variable $u_{2k}$ in the Lax operator $L$ through a new operator $B ...
