Calibrating Change-Point Inference in Regional Rainfall Extremes: Evidence from Mizoram, Northeast India

Abstract Regional rainfall studies often detect a change point and test the resulting periods as if the break had been specified in advance, a procedure that severely inflates false positives when the break is instead selected from the same data being tested. We quantify this inf...

Does Citizen Science Reach the Citizen? Exploring the Science–Society Interface Through Scholarly and Societal Attention

Abstract The study applied an Altmetric approach to examine the science-society interface in citizen science research. Bibliographic data were collected from Scopus for 10,285 articles published between 2016 and 2025. Altmetric data corresponding to the 100 most highly cited arti...

Land cover change and vegetation trends in South Darfur Sudan using dynamic world

Land use and land cover change (LULCC) in semi-arid regions provides important insights into environmental dynamics under climate variability and socio-political disturbance. This study investigated the spatiotemporal dynamics of land cover, vegetation greenness, and climate vari...

ON ϵ–PARA SASAKIAN MANIFOLDS ADMITTING ∗–CONFORMAL η–RICCI SOLITONS

This paper characterizes $\epsilon$--para Sasakian manifolds admitting a $*$--conformal $\eta$--Ricci soliton. We analyze solitons under diverse geometric conditions, namely, generalized Ricci recurrence, flatness of specific $\mathcal{W}_i$--curvature tensors ($i=6,7,8$), and $\...

Global forest governance in a fragmenting post-world war II order – What should remain?

After the events of the second World War, nations leaned toward multilateralism, and the post-World War II multilateral order provided a space where forests could be discussed through cooperation, aid, rights, development, and shared responsibility. Our policy forum argues that a...

Underrepresented food culture and culinary journey of selected foreign communities of Kolkata

Kolkata, over the centuries, has adopted, accepted, and included communities from across the globe, creating the present-day Kolkata platter through food evolution. Historical connotations and literary descriptions are mostly on colonial, Chinese, Mughlai, and Awadhi influences....

Vegetation dynamics in Mizoram Northeast India from 2005 to 2025 using landsat imagery and image specific NDVI thresholding

Vegetation monitoring is important for evaluating landscape change in ecologically sensitive mountain regions. This study assessed vegetation dynamics across Mizoram, India, an eastern Himalayan-extension landscape, between 2005 and 2025 using Landsat 5 Thematic Mapper and Landsa...

Metamaterial assisted hybrid response from frequency selective surface roll off and leaky wave resonator integrated antenna for underground applications

Abstract In emerging era of wireless technologies such as cognitive radio, wireless sensor networks etc., designing effective low frequency antennas < 1000 MHz and specifically < 700 remains a significant challenge due to its poor (often negative) gain and severely limited bandwi...

Biochar in Ecological Restoration of Degraded Lands, Soil Health, and Food Crops Safety

ABSTRACT Agro‐chemicals intensive agriculture, coupled with biomass burning in ‘ethno‐agricultural systems’ or shifting cultivated Jhum lands, stress the global agroecosystems with soil degradation and expanding marginal lands, causing food security and public health safety chall...

Nonsmooth KKT-type optimality and duality for multiobjective fractional bilevel optimization via tangential subdifferentials

This paper studies a class of nondifferentiable multiobjective fractional bilevel optimization problems. Under suitable nonsmooth constraint qualifications, necessary optimality conditions of the Karush– Kuhn–Tucker (KKT) type are established using tangential subdifferentials. Su...

Multivariate Discriminant Analysis of Oxygen Saturation Level, Organic Pollution, Thermal Profile, and Chloride Variances between Tlawng and Tuirial River Systems in Aizawl, India

Objectives: The present study was intended to compare the water quality of two rivers, Tlawng and Tuirial as per their dissolved oxygen, biological oxygen demand, chloride and water temperature and to find out the variables which best discriminated the two river systems and seaso...

Higher-order stable compact ADI schemes for multi-term time-fractional diffusion-wave equation in two dimensions

This article focuses on developing the compact alternating direction implicit (ADI) numerical scheme based on H3N3-2 σ approximation for the two-dimensional multi-term time-fractional diffusion wave equation (TFDWE). The time-dependent multi-term Caputo derivative of order α r ∈...

Mapping and monitoring land usage changes of gum Arabic belt in armed conflict-disturbed areas to support sustainable management of the belt

Abstract The Gum Arabic Belt (GAB) in Sudan play a key role in sustaining rural livelihoods, supporting biodiversity, and delivering essential ecosystem services. However, this fragile dryland ecosystem is increasingly threatened by armed conflict, large-scale displacement, land...

Facile synthesis of black phosphorus nanoflakes by hydrothermal method for hydrogen sensing application

This article presents a direct method of producing Black Phosphorus (BP) from red phosphorus through hydrothermal aqueous method by using Ethylene Diamine and De-Ionized water, followed by fabricating a BP-based gas sensor. This work presents a low-temperature, low-cost synthesis...

Global research trends in ecosystem health assessment for nature-based solutions using scientometric analysis

Human survival depends on ecosystems, which are an essential component of the earth’s environment. Researchers and professionals are increasingly interested in ecosystem health issues and their nature-based solutions, but disparities persist. A total of 1273 research articles wer...

AlN Spacer-Induced Improvement in DC, RF, and Breakdown Characteristics of AlN Buffered AlGaN/GaN HEMTs

Abstract This work presents a comprehensive DC and AC performance analysis of AlN buffered AlGaN/GaN HEMTs without (w/o) and with an AlN spacer using TCAD simulations. The incorporation of the AlN spacer substantially enhances the HEMT performance through improved polarization in...

Seasonal variation in physicochemical properties of some agricultural soils in Lucknow district, Uttar Pradesh of India
