When Are Statistical Forecast Gains Economically Relevant? Evidence From Bitcoin Returns

Journal of Forecasting, EarlyView.
ABSTRACT We study how statistical forecast gains for Bitcoin translate into trading profits. Using real‐time out‐of‐sample forecasts from daily bivariate VARs from October 2021 to February 2024, we show that Bitcoin returns are forecastable and that seven predictive indices yield significant gains in directional accuracy (DA).

Revisiting the Nexus Between Trade Liberalisation and Income Inequality: The Case of Sub‐Saharan African Countries

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper examines the impact of trade liberalisation on income inequality across 24 Sub‐Saharan African (SSA) countries from 2000 to 2020. Using IV‐Tobit and 2SLS models, we consistently find that greater trade openness significantly exacerbates inequality in the region. Critically, we document an inverted U‐shaped relationship between trade

On the critical values of L-functions of GL(2) and GL(2)×GL(2)

Duke Mathematical Journal, 1994
Let \(\lambda\) be a primitive cuspidal automorphic form for \(GL_2 (F)\), where \(F\) is a number field. According to well-known conjectures (Shimura, Taniyama, Langlands), there should exist a rank 2 motive \(M (\lambda)/F\) attached to \(\lambda\) such that the \(L\)-function \(L(M (\lambda) \otimes M (\varphi), s)\) is equal to the Hecke-Langlands \

Exploring the Link Between Psoriasis and Genetic Predictors of Cardiac Magnetic Resonance Traits: A Bidirectional Mendelian Randomization Study

iNew Medicine, EarlyView.
ABSTRACT Psoriasis is a chronic autoimmune disease characterized by systemic inflammation and skin involvement, affecting millions of individuals worldwide. However, few studies have evaluated whether psoriasis and cardiac magnetic resonance imaging (CMR) traits share a common genetic basis.

Adipose‐derived small extracellular vesicles exacerbate microvascular dysfunction in heart failure with preserved ejection fraction via mmu‐miR‐582‐3p‐mediated Rap1b suppression

Interdisciplinary Medicine, EarlyView.
This study reveals that small extracellular vesicles (sEVs) from visceral fat compromise coronary microcirculation in a mouse model of heart failure with preserved ejection fraction (HFpEF). The SGLT2 inhibitor canagliflozin emerges as a therapeutic strategy, improving cardiac function and endothelial health.

Optimization of light spectrum and intensity to enhance growth and metabolite profiles in green and purple radish microgreens cultivated in a vertical farming system

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Microgreens have emerged as a promising crop in vertical farming due to their high nutritional value and short growth cycles. Light spectrum and intensity are critical factors influencing biomass production and metabolic activity in plants, particularly in controlled environments such as vertical farming systems. This study aimed to
