Evaluating Forecasts at Multiple Horizons: An Extension of the Diebold–Mariano Approach

open access: yesJournal of Forecasting, Volume 45, Issue 5, Page 2379-2392, August 2026.
ABSTRACT Forecast accuracy tests are fundamental tools for comparing competing predictive models. The widely used Diebold–Mariano (DM) test assesses whether differences in forecast errors are statistically significant. However, its standard form is limited to pairwise comparisons at a single forecast horizon.

Two‐Point Change Patterns of LDL‐Cholesterol and hs‐CRP and Risk of Major Adverse Cardiovascular Events in Middle‐Aged and Older Chinese Adults: A Prospective Cohort Study

open access: yesHealth Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background and Aims The associations of two‐point change patterns of low‐density lipoprotein cholesterol (LDL‐C) and high‐sensitivity C‐reactive protein (hs‐CRP) with major adverse cardiovascular events (MACE) remain underexplored, particularly in Chinese populations.

Effect of Re or W Addition on the Oxidation Behaviour of a Compositionally Complex Ta–Mo–Cr–Ti–Al Alloy in Air at 1000°C

open access: yesMaterials and Corrosion, Volume 77, Issue 8, Page 1222-1233, August 2026.
The effect of addition of 3 at.% of either Re or W on the oxidation performance of equimolar Ta–Mo–Cr–Ti–Al is investigated and found to be beneficial, at least temporarily. Additionally, the oxide (Ti,Ta)O2 has been identified and characterised as a main part of the oxide scale. ABSTRACT Presuming that doping of protective (Cr,Ta,Ti)O2 with cations of

Purification and Properties of Polyvinyl Nitrate and Its Compatibility With Solid Oxidizers

open access: yesPropellants, Explosives, Pyrotechnics, Volume 51, Issue 8, Page 1224-1234, August 2026.
ABSTRACT Polyvinyl nitrate (PVN) is a nitrate‐ester energetic binder that can be produced directly from polyvinyl alcohol—a cheap commodity feedstock—thereby offering potential cost and supply‐chain advantages over binders based on nitrocellulose and other specialty polymers.

The impact of physiological oxidants on triggering amyloid formation of the cell cycle regulator protein p16INK4A

open access: yesProtein Science, Volume 35, Issue 8, August 2026.
Abstract The tumor suppressor protein p16INK4a plays a key role in cell cycle control and is frequently inactivated in human cancers. We previously discovered that oxidation of its single cysteine residue induces a structural transition from the functional monomeric form into inactive amyloid fibrils.

Comparing Monte Carlo Models of Impact Alteration of Planetary Atmospheres

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract One process that affects atmospheric surface pressure is impact bombardment. The evolution of a planet's atmosphere under impact bombardment is an open question. We use a Monte Carlo method to evolve a range (0.006–92.5 bar) of initial atmospheres at Mars, Earth, and Venus under bombardment of 5×106 $5\times 1{0}^{6}$ impactors using seven ...

The Length of Martian Crater Rays and Their Relation to Lunar Cold Spots

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Impact‐generated crater rays are well‐documented on the Moon, with most appearing as high‐albedo streaks extending radially from a crater's center. On Mars, however, crater rays are significantly rarer and discernible only through thermal imaging due to their lower thermal inertia compared to surrounding terrain.
