Accounting for animal health in efficiency analysis: An application to Swedish dairy farms

American Journal of Agricultural Economics, EarlyView.
Abstract Poor animal health is a central concern in modern livestock production. Despite the necessity to incorporate animal health in efficiency analysis, the theoretical and empirical developments are limited on this subject. This article appropriately characterizes the axiomatic properties of animal health within a production framework.

Perivascular Spaces as Determinants of Amyloid, Tau, and Vascular Biomarker Progression

Annals of Neurology, EarlyView.
Objective Magnetic resonance imaging (MRI)‐visible enlarged perivascular spaces (PVS) are markers of cerebral small vessel disease (SVD) and aging, processes implicated in both neurodegenerative and cerebrovascular pathologies. However, longitudinal positron emission tomography (PET) studies examining PVS as a mechanism underlying Alzheimer's disease ...

Mixed interpolating–smoothing splines and the ν-spline

Journal of Mathematical Analysis and Applications, 2006
Let \(X\), \(Y\), \(Z_{1}\) and \(Z_{2}\) be Hilbert spaces with inner products \(\langle\;,\;\rangle_{X}\), \(\langle\;,\;\rangle_{Y}\), \(\langle\;,\;\rangle_{Z_{1}}\) and \(\langle\;,\;\rangle_{Z_{2}}\) respectively, and let \(T:X\rightarrow Y\), \(\Lambda _{1}:X\rightarrow Z_{1}\), \(\Lambda _{2}:X\rightarrow Z_{2}\) and \(\pi :Z_{2}\rightarrow Z_ ...

Compositional Time–Temperature–Transformation and Post‐Processing Window Mapping of Epoxy Nanocomposites via Machine Learning

Journal of Applied Polymer Science, EarlyView.
Discrete DSC and rheological data are transformed into continuous compositional Time–temperature–transformation (TTT) diagrams through physics‐informed Gaussian Process Regression. The proposed framework quantitatively predicts post‐gel processing windows across temperature and nanofiller composition, providing a practical route for accelerated design ...

Prophylactic Enoxaparin Reduces Symptomatic Venous Thromboembolism Compared With No Chemoprophylaxis Within 95 Days After Knee Arthroscopy

Arthroscopy, EarlyView.
Purpose To investigate whether prophylactic use of low‐molecular‐weight heparin (enoxaparin) after knee arthroscopy reduces the incidence of symptomatic venous thromboembolism (VTE) compared with no postoperative pharmacological prophylaxis. Methods We conducted a population‐based cohort study using linked national insurance and hospital data from ...

Explicit B-spline regularization in diffeomorphic image registration

Frontiers in Neuroinformatics, 2013
Diffeomorphic mappings are central to image registration due largely to their topological properties and success in providing biologically plausible solutions to deformation and morphological estimation problems.

Challenges and Opportunities in Multi‐Method Integrated Geophysical Prospection of Buried Building Remains at the Sanctuary of Olympia

Archaeological Prospection, EarlyView.
ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.
