Sustainable Production Planning: Insights Into Factors, Models, and Solution Methods
Sustainable Development, EarlyView.ABSTRACT Effective resource management remains a major challenge for organizations seeking to balance economic efficiency with environmental and social responsibility. In this context, production planning becomes a strategic mechanism for integrating sustainability into industrial operations.

Multiple Outbursts of Halley-type Comet 12P/Pons–Brooks
The Astronomical JournalWe present optical observations of the Halley-type comet 12P/Pons–Brooks (12P) on its approach to perihelion. The comet was active even in the first observations at ∼8 au.

The effect of multiple encounters on short period comet orbits [PDF]
, 1972 The observed orbital elements of short period comets are found to be consistent with the hypothesis of derivation from long period comets as long as two assumptions are made.

Bias Polarity Switching (BiPS): A Transient Method for Probing Interfacial Carrier Dynamics
Small Methods, EarlyView.Bias Polarity Switching combines optical excitation with rapid bias reversal to probe near‐interface carrier accumulation, trapping, detrapping, and extraction together with bulk carrier transport. The method provides access to defect kinetics and contact‐related transport processes, offering a complementary approach for investigating semiconductor ...

steel research international, EarlyView.A hybrid framework combining a mechanistic tanks‐in‐series model, thermodynamic data, and statistical learning methods was developed for continuous temperature prediction during RH vacuum treatment. The framework accounts for temperature changes caused by alloy additions, O2 blowing via top lance, and heat losses to the surroundings. Validation against

How Long-lived Grains Dominate the Shape of the Zodiacal Cloud
The Planetary Science JournalGrain–grain collisions shape the three-dimensional size and velocity distribution of the inner Zodiacal Cloud and the impact rates of dust on inner planets, yet they remain the least understood sink of zodiacal dust grains. For the first time, we combine

Oort Cloud Comets: Perturbations Due to the Passage of Gliese 710
UniverseThe outermost region of the Solar System is called the Oort cloud, which is the Solar System’s reservoir of long-period comets that extends to distances up to 200,000 au from the Sun.

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption
Environmental Toxicology, EarlyView.ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

On the Early Thermal Processing of Planetesimals during and after the Giant Planet Instability
The Planetary Science JournalBorn as ice-rich planetesimals, cometary nuclei were gravitationally scattered onto their current orbits in the Kuiper Belt and the Oort Cloud during the giant planets’ dynamical instability in the early stages of our solar system’s history.

Long-term orbital evolution of short-period comets found in Project Cosmo-DICE [PDF]
, 1992 Orbital evolutions of about 160 short-period (SP) comets are numerically integrated for 4400 years in the framework of a realistic dynamical model. By the round-trip error in closure test, a reliable time space of the integrated orbits is estimated for ...
