Assessment of vegetation carrying capacity at the basin-scale using an improved SWAT model

Kivalov S., Catena 2026 Vol. 263 Article 109767

Vegetation restoration represents a highly effective strategy for offsetting carbon emissions, mitigating climate change, and enhancing the quality of the eco-environment. Despite the ecological benefits, the large-scale ‘Grain-for-Green’ program in China has caused unintended hydrological consequences, threatening the sustainability of regional water resources in this arid and semi-arid region.

Flamarion M. V., Pelinovsky E., Nonlinear Dynamics 2026 Vol. 114 Article 784

In this article, we investigate wave packet and solitary wave dynamics in the Whitham–Ostrovsky (WO) equation. By means of a multiple-scales expansion, we formally derive a nonlinear Schrödinger (NLS) equation governing the envelope evolution.The corresponding modulational stability diagram is then obtained using the Lighthill criterion. We show that sufficiently large values of the low-frequency dispersive term render ...

Green synthesis of Bi-functional silica nanoparticles towards highly efficient photocatalysis and antibacterial application

Hazarika A. P., Das A., Das S. K. et al., Physica B: Condensed Matter 2026 Vol. 738 Article 418803

Lemon grass (Cymbopogon citratus, LG-SiO2), horsetail (Equisetum debile, SG-SiO2), and cassava leaves (Manihot esculenta, CL-SiO2) were used to green-synthesize silica (SiO2) nanoparticles (NPs). While LG-SiO2 and SG-SiO2 had strong (101) peaks and a large 22° amorphous peak, XRD of CL-SiO2 verified crystallinity. LG-SiO2 (agglomerated porous), SG-SiO2 (rectangular-cube agglomerates), and CL-SiO2 (flake agglomerates) had different morphologies. The TEM image of LG-SiO2 revealed agglomerated ...

Signatures of Reconnection and a Split Heliospheric Tail in High-energy Energetic Neutral Atoms

Kornbleuth M., Opher M., Drake J. F. et al., Astrophysical Journal 2026 Vol. 1004 No. 1 Article 1

The shape of the heliosphere, regarded as comet-like since the 1960s, has recently been the subject of intense debate in the last decade. There is disagreement as to whether the heliospheric tail extends to ∼10,000 au in a comet-like shape or if it is short (∼400 au) with a split. Energetic neutral atom (ENA) maps from ...

Nishant T., Kartsev A., Saswata G. et al., Journal of Materials Chemistry C 2026 Article -

Overheating remains a critical limitation in high-performance electronic and computing systems, necessitating the development of efficient thermal management fluids. In this work, a magnetically responsive hybrid ferrofluid was developed by incorporating two-dimensional hexagonal boron nitride (2D-hBN) nanosheets into a Mn–Zn–ferrite-based ferrofluid. The hybrid system retains magnetic responsiveness while leveraging the high in-plane thermal conductivity and chemical stability of 2D-hBN nanosheets. ...

The critical role of shear antiphase boundaries in τ-Mn(Al,Ga) rapidly quenched alloy

Fortuna A. S., A.I. Kartsev, Gorshenkov M. V. et al., Journal of Alloys and Compounds 2026 Vol. 1070 Article 188711

The τ-phase in Mn-Al-Ga alloys is a promising candidate for rare-earth-free permanent magnets. This study re-veals that the τ(γ₂)-phase in rapidly quenched Mn55Al36Ga9 ribbons contains a high density of dislocations, which form antiphase boundaries (APBs). Using transmission electron microscopy and density functional theory, we demonstrate that Mn atoms at these APBs couple antiferromagnetically. This antiferromagnetic interaction is identified ...

Combined Experimental and Ab Initio Study of Sc Doping in MgB2: Decoupling Electronic and Microstructural Effects on Superconductivity

Dikhtievskaya K., Argunov E., Alexey I. Kartsev et al., The Journal of Physical Chemistry Letters 2026 Vol. 17 No. 17 P. 4999–5004

In this study we revealed the effect of scandium doping on the electronic and superconducting properties of the MgB2 compound. Calculations demonstrate that Sc substitutes for Mg atoms, acting as an electron donor. Mg substitution diminishes the density of states in the σ-band and attenuates the electron–phonon coupling, thereby elucidating the reduction in critical temperature. Simultaneously, ...

Gabdullin N., Androsov I., / Series Computer Science "arxiv.org". 2026.

Label prediction in neural networks (NNs) has O(n) complexity proportional to the number of classes.

Implementing Transport Coding in OMNeT++ for Message Delay Reduction

Petrovanov I., Sergeev A., / Series Computer Science "arxiv.org". 2025. No. 2512.18332.

Transport coding reduces message delay in packet-switched networks by introducing controlled redundancy at the transport layer: original packets are encoded into coded packets, and the message is reconstructed after the first successful deliveries, effectively shifting latency from the maximum packet delay to the -th order statistic. We present a concise, reproducible discrete-event implementation of transport coding in OMNeT++, including ...
