Alternative Data for Realised Volatility Forecasting: Limit Order Book and News Stories

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT We examine whether two major alternative data sources, limit order book information and firm‐specific news, provide incremental predictive information for daily realised volatility forecasting within the HAR‐family, using a parsimonious framework to ensure practical implementation and comparability. The framework is designed for practical real‐

Temperature and heat‐load exposure effects on preterm births: Insights from a population‐based study using distributed lag non‐linear models

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Preterm birth presents a substantial health, psychological, and economic burden worldwide. Environmental factors, including temperature fluctuations, are known to influence the risk of preterm birth. This study aimed to investigate the association between high temperatures and heat load and preterm births. Methods Using a time‐series

Human biomarker navigator

open access: yesiMeta, EarlyView.
The Human Biomarker Navigator integrates the disease continuum, biomarker dynamics, cross‐organ biomarker networks, biomarker classification, and technology‐driven paradigms. It maps how biomarkers link multi‐system physiology and pathology across the nervous, respiratory, endocrine, circulatory, immune, digestive, urinary, reproductive, and ...

Endohedral fullerenes as qubits: From synthesis to quantum computing applications

open access: yesInfoMat, EarlyView.
Endohedral fullerenes emerge as promising platforms for qubits and qudits. This review surveys the primary synthesis routes, from arc‐discharge to high‐yield molecular surgery. It then details spin manipulation and readout in key systems, including metal‐based, cluster, and nitrogen‐containing fullerenes.

Normative scores and clinical cut‐offs of the Cyclothymic–Hypersensitive Temperament Questionnaire in adolescence

open access: yesJCPP Advances, EarlyView.
Abstract Background The Cyclothymic–Hypersensitive Temperament (CHT) is a multidimensional, transdiagnostic affective disposition characterized by mood instability, interpersonal sensitivity, heightened emotional reactivity and impulsive behaviors. The CHT Questionnaire (CHTQ) currently lacks of normative references and empirically derived thresholds ...

Characteristic classes and representations of discrete subgroups of Lie groups [PDF]

open access: yesBulletin of the American Mathematical Society, 1982
A volume invariant is used to characterize those representations of a countable group into a connected semisimple Lie group G which are injective and whose image is a discrete cocompact subgroup of G. Let IT be a discrete cocompact subgroup of G and consider the analytic variety Hom(7r, G) consisting of homomorphisms 0: TT —> G.

Line Graphs of Multigraphs and the Forbidden Graph E 6

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT The line graph Γ of a multigraph Δ is the graph whose vertices are the edges of Δ, where two such edges are adjacent if and only if they meet in a single vertex of Δ. We provide several characterizations of such line graphs and in particular show that a graph is a line graph if and only if it does not contain one of the 32 graphs, all of which

A Framework for Subgroup Dynamics Through the System Dynamics Lens: An Integrative Review of the Attribute and the Network Views

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT Subgroups are dynamic entities evolving constantly in response to changing contexts and time. Although scholars from both the attribute and the network views have acknowledged that subgroups are inherently complex and fluid, research in these traditions has remained bifurcated, with limited efforts to integrate the two perspectives to more ...

Similar dynamic tibiofemoral movements during jump‐landing and walking but distinct hamstrings strength across ACL reconstruction autograft types at mid‐term follow‐up

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Dynamic tibiofemoral movements following anterior cruciate ligament reconstruction (ACLR) with quadriceps tendon (QT) autografts have not yet been compared to other autografts. We aimed to compare dynamic anterior tibial translation (ATTd) and internal tibial rotation (ITRd) during jump‐landing and walking among patients with QT, bone ...

Hearing the Serre Invariant of a Compact p‐Adic Analytic Manifold

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT Using a previous novel way of defining kernel functions for Laplacian integral operators on a compact p$p$‐adic analytic manifold X$X$, one such operator Δ0s$\Delta _0^s$ with s∈R$s\in \mathbb {R}$ is applied to hearing the Serre invariant i(X)$i(X)$ by showing that a wavelet eigenvalue (with the wavelet having small support) is always ...
