Semiparametric Innovation-Based Tests of Orthogonality and Causality Between Two Infinite-Order Cointegrated Ceries with Application to Canada/US Monetary Interactions [PDF]

open access: yes
We propose a semiparametric approach for testing orthogonality and causality between two infinite-order cointegrated vector autoregressive IVAR(1) series. The procedures considered can be viewed as extensions of classical methods proposed by Haugh (1976,

Cost Pass‐Through in Crisis: Evidence From the German Malt‐Beer Supply Chain

open access: yesAgribusiness, EarlyView.
Abstract Global agri‐food supply chains are increasingly exposed to geopolitical shocks, climate volatility, and market consolidation, factors that disrupt traditional price relationships and reshape market power dynamics. Nowhere is this more visible than in the brewing sector, where agricultural raw materials meet complex industrial processing and ...

Sex‐Based Body Composition Changes in Patients With Rectal Cancer Undergoing Preoperative Chemoradiotherapy: A Prospective Observational Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This prospective study observed that preoperative chemoradiotherapy for rectal cancer was associated with reductions in body fat and grip strength, which appeared to be more pronounced in female patients. These findings suggest that sex‐sensitive nutritional and exercise support may be beneficial to help maintain muscle mass and physical function ...

Lymphocyte‐C‐Reactive Protein Ratio as Promising New Marker for Predicting Surgical Site Infection in Children With Ulcerative Colitis

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Surgical site infection (SSI) is a major complication after ileal pouch–anal anastomosis (IPAA) in pediatric ulcerative colitis (UC), significantly impairing quality of life. The lymphocyte‐to–C‐reactive protein ratio (LCR), a composite marker of systemic inflammation and immune/nutritional status, has emerged as a potential ...

A REVIEW OF ALTERNATIVE EXPECTATIONS REGIMES IN COMMODITY MARKETS: SPECIFICATION, ESTIMATION, AND HYPOTHESIS TESTING USING STRUCTURAL MODELS

open access: yes
Price expectations play a critical role in commodity markets where producers must make input decisions well before output is realized. This paper brings together alternative expectations regimes, their estimation, and hypothesis tests for use in ...

Prognostic Impact of Metastasis Timing in Metastatic Gastrointestinal Stromal Tumors: A Multicenter Retrospective Cohort Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Gastrointestinal stromal tumors (GISTs) commonly metastasize to the liver and peritoneum. Metastases may be detected synchronously at the time of initial diagnosis or develop metachronously after curative‐intent resection. Nonetheless, the prognostic significance of metastasis timing in advanced GIST remains unclear.

Macrophage Phenotype Detection Methodology on Textured Surfaces via Nuclear Morphology Using Machine Learning

open access: yesAdvanced Intelligent Discovery, EarlyView.
A novel machine learning approach classifies macrophage phenotypes with up to 98% accuracy using only nuclear morphology from DAPI‐stained images. Bypassing traditional surface markers, the method proves robust even on complex textured biomaterial surfaces. It offers a simpler, faster alternative for studying macrophage behavior in various experimental
