Band‐Pass Filtering With High‐Dimensional Time Series. A Synthetic Indicator of the Medium‐to‐Long Run Component of Growth

Journal of Time Series Analysis, EarlyView.
ABSTRACT The paper deals with the construction of a synthetic indicator of economic growth, obtained by projecting a quarterly measure of aggregate economic activity, namely gross domestic product (GDP), into the space spanned by a finite number of smooth principal components, representative of the medium‐to‐long‐run component of economic growth of a ...

Experiences of accessing psychological therapies for self‐harm: A qualitative study of stakeholders' perspectives

Psychology and Psychotherapy: Theory, Research and Practice, EarlyView.
Abstract Objectives While rates of self‐harm are rising in the United Kingdom, people who self‐harm can often struggle to access appropriate treatment. This study sought to explore adult stakeholders’ perspectives and experiences of the barriers to, and facilitators of, accessing support for self‐harm and also how services could be better tailored to ...

Why Politicians Misbehave: A Systematic Review of How Attributes of Political Office Affect Moral Decision‐Making and Behavior

Public Administration Review, EarlyView.
ABSTRACT The moral decision‐making and behavior of politicians is influenced by the distinctive and characteristic attributes of political office. This literature review analyzes 80 articles from public administration, political science and related disciplines to systematically map these attributes and their underlying mechanisms. This study identifies

Is the World Getting Smaller? Network‐Driven Heterogeneity in Gravity‐Model Elasticities

The World Economy, EarlyView.
ABSTRACT Gravity models constitute the workhorse of empirical international trade research, yet the temporal stability of their core parameters—distance and GDP elasticities—remains underexplored, particularly in relation to the evolving structure of trade networks.

Collaborative platooning and routing for mixed fleets of electric automated vehicles and conventional trucks

International Transactions in Operational Research, Volume 34, Issue 1, Page 460-500, January 2027.
Abstract The application of automated ground vehicles (AGVs) is well‐established in closed environments such as port terminals, while their operation in open areas remains challenging. In this work, we set out to overcome this limitation by introducing platooning as a transfer mode in heterogeneous vehicle networks.

Boosting PM2.5 short-term prediction by coupling graph attention and koopman networks

Computational Urban Science
Accurately predicting PM2.5 concentrations remains a major challenge due to the complex and nonlinear nature of its formation and transport processes. Traditional models often struggle to capture the spatiotemporal dynamics of PM2.5, particularly under ...

Single‐Cell Integration of Mouse Models of Autism Reveals Conserved Transcriptomic Signatures of Excitatory‐Inhibitory Imbalance and Glial Dysfunction

Glia, Volume 74, Issue 12, December 2026.
Integrated scRNA‐seq from 11 ASD models reveals convergent E/I imbalance and glial dysfunction. Conserved astrocyte and oligodendrocyte dysregulation transcend model‐specific variability. Validated by human datasets. ABSTRACT The etiological heterogeneity of autism spectrum disorder (ASD) complicates identifying core molecular mechanisms.
