Fixed-point theory and metric spaces69IMPACT SIGNAL
Evidence of global relevance

A perspective on Banach and Kannan mappings contracting the perimeter of triangles in interpolative metric spaces

This theoretical article studies mappings that contract triangle perimeters in interpolative metric spaces. It establishes a necessary-and-sufficient fixed-point condition, extends Kannan-type results beyond ordinary metric spaces and proposes a sufficient uniqueness condition with examples. Its contribution is mathematical generalisation rather than empirical evidence.

Treated rice straw and goat nutrition69IMPACT SIGNAL
Evidence of global relevance

Evaluation of urea–molasses-treated rice straw as a partial replacement for Brachiaria mutica in diets of growing Boer crossbred goats

A five-goat Latin-square trial in the Mekong Delta replaced para grass with urea-molasses-treated rice straw at 0-100%. Higher levels improved some digestibility measures but reduced intake, daily gain and feed conversion. Growth did not differ between 0% and 25%, suggesting moderate use during forage shortages rather than complete replacement.

Freshwater fungal taxonomy69IMPACT SIGNAL
Evidence of global relevance

Unveiling freshwater fungi from the Hanjiang River Basin in South China: Introducing Neolindgomyces guttulatus sp. nov. (Lindgomycetaceae, Pleosporales)

A downstream Hanjiang River collection in China had distinctive morphology and multilocus phylogeny, supporting Neolindgomyces guttulatus as a new species and the first Chinese freshwater record of the genus. The work expands fungal diversity knowledge but does not establish ecological function or distribution.

Smartphone movement biomechanics69IMPACT SIGNAL
Evidence of global relevance

Biomechanical constraints of excessive adiposity on smartphone-derived directional acceleration and dynamic balance during unilateral sit-to-stand transitions in young adults

Sixty young women completed five single-leg sit-to-stand transitions with a smartphone at S2. The highest-body-fat group took longer and showed different anteroposterior, mediolateral and vertical accelerations than the normal-fat group, while total acceleration did not differ. Smartphone sensing may be a low-cost movement measure, not a diagnostic test or proof of causation.

Liver fluke infection and reinfection69IMPACT SIGNAL
Evidence of global relevance

Longitudinal changes and risk factors of Opisthorchis viverrini infection after selective praziquantel treatment: evidence from urine antigen assay and fecal examination in an endemic community in Northeast Thailand

A 24-week prospective cohort of 612 people in a northeastern Thai endemic community found baseline prevalence of 41.0% by urine antigen versus 8.1% by faecal examination, with roughly tenfold higher incidence and reinfection estimates from the urine assay. Raw-fish consumption in the previous six months carried an adjusted risk ratio of 7.52. Drug treatment alone will not interrupt transmission if behavioural and environmental exposure persists.

CAR T cells and liver cancer69IMPACT SIGNAL
Evidence of global relevance

Comparative in vitro evaluation of fourth-generation anti-GPC3 CAR T-cells in hepatocellular carcinoma

A Siriraj team compared second-, third- and fourth-generation anti-GPC3 CAR T cells. Among 195 HCC biopsies, 82.6% were GPC3-positive, and the fourth-generation construct showed the strongest killing in monolayer and spheroid models, with antigen-dependent proliferation and a moderated acute cytokine profile. All efficacy evidence remains in vitro.

Smart-meter NB-IoT and machine learning69IMPACT SIGNAL
Evidence of global relevance

ML-Based Feasibility-Prediction for NB-IoT Smart Metre Deployment in Thailand: A Cross-Environment Multi-Site Study

Using Thai channel measurements, classifiers predicted whether NB-IoT would achieve 95% RSRP coverage across 411 cells at four sites. Gradient Boosting reached 0.971 accuracy, 0.969 F1 and 1.7 ms inference, far faster than Monte Carlo. However, training labels came from Monte Carlo under the same assumed channel model, so this emulates simulation rather than proving field-deployment accuracy.

LLMs and software effort estimation69IMPACT SIGNAL
Evidence of global relevance

Hybrid intelligence effort for software effort estimation in LLM assisted development

A controlled experiment with 22 developers, 110 real-world tasks and three LLMs proposed Hybrid Intelligence Effort, combining model work with human oversight. Story Points retained partial value, but validation and corrective intervention dominated effort; HIE dimensions reportedly explained about 72-80% of observed variance. Results may vary by model, team and task.

Evidence of global relevance

Cytogenetics Study of Habenaria janellehayneana Choltco, B.Moloney & Yong, H. rhodocheila Hance and Nervilia khaoyaica Suddee, Watthana & S.W.Gale, Rare Species of Family Orchidaceae from Thailand

Thai researchers analysed chromosomes of Habenaria janellehayneana, H. rhodocheila and Nervilia khaoyaica. Both Habenaria had 2n=42 but different karyotypes, while Nervilia had 2n=36. Multivariate analyses separated genera and species, providing taxonomic and conservation baselines without directly measuring population size or extinction risk.

NB-IoT channels in Thailand69IMPACT SIGNAL
Evidence of global relevance

Narrowband IoT Channel Characterisation Across Multiple Environments in Thailand

Measurements at 16 central and western Thai sites across five environments produced 8,000 RSRP samples. Path-loss exponents ranged from 2.2 in rural terrain to 4.0 in forest/mountain settings, with distinct fading and shadowing. The parameters support Thai NB-IoT planning but do not represent the entire country, seasons or all operators.

Natural-rubber aerogel insulation69IMPACT SIGNAL
Evidence of global relevance

Effect of Pre-Vulcanization Time on Structure and Thermal Insulation of Natural Rubber Latex/Silica Aerogel Composites

Natural-rubber-latex/silica-aerogel composites made with eight-day pre-vulcanised latex had greater crosslink density, better preserved aerogel pores and 42.41% lower thermal conductivity than the zero-day formulation. The material remained flexible and thermally stable to 387.3°C, but mechanical durability, service life and fire behaviour were not established.

Development and Characterization of Andrographolide Microparticles via Spray Drying: An Aqueous-Based Chitosan/Cellulose/Poloxamer Carrier Approach

A Naresuan University team developed spray-dried andrographolide microparticles using an aqueous chitosan-cellulose-poloxamer carrier. The selected particles were 3-5 micrometres, released 89.23% in four hours and reduced Influenza A/H1N1 titre by 3.3 log10 in laboratory testing. Safety and efficacy after inhalation in animals or people remain untested.
