Segmental pin and endwall heat transfer for a staggered pin fin array in a stationary and rotating channel

An experimental study is conducted to separate the heat transfer contributions of the pin surfaces and endwalls in a staggered circular pin fin array subjected to straight flow ejection in a low aspect ratio rectangular channel, representative of gas turbine trailing edge cooling...

Resilience Assessment of Reinforced Concrete Bridges in a Multihazard Environment of Flood and Corrosion

Abstract Extreme floods pose significant threats to bridges, specifically due to hydrodynamic forces on inundated bridge superstructures and foundation scour, which can cause excessive lateral deflection at the deck level and instability of bridges. Such bridge damage produces im...

Emzing: A Deep Learning-Enabled Software Suite for End-to-End Analysis of High-Resolution LC-MS Metabolomics Data

Abstract High-resolution LC-MS-based metabolomics requires transforming noise-dominated raw data into quantitative feature tables and, ultimately, biologically meaningful insights. In practice, this process is fragmented across multiple tools and involves extensive parameter tuni...

Automated Roadside Vegetation Management Using LiDAR-Based Geospatial Simulations

Abstract Effective roadside vegetation management is vital for safety, visibility, and infrastructure longevity. Traditional methods are often labor-intensive, time-consuming, and difficult to scale. This paper presents a novel approach leveraging light detection and ranging (LiD...

Investigating the Sensitivity of Hydrological Model Calibration to Noise in Forcing and Response Variables

In this study, the sensitivity of hydrological model calibration to noise in both input and output variables was investigated using the Soil and Water Assessment Tool (SWAT). Singular Spectrum Analysis (SSA) was utilised to remove noise fully as well as partially from the input d...

Experimental investigation of local heat transfer in multiple free surface triangular jet impingement and generalised thermal–hydraulic comparison of orifice shapes

Free surface jet impingement is an effective technique for high heat flux cooling. The flow field and heat transfer characteristics are strongly affected by the orifice geometry. The present study experimentally examines a symmetric 3 × 3 array of free surface triangular water je...

Environmental Pollution in Food Production and Pathways for Mitigation through Sustainable and Circular Approaches

Abstract Global food production is under increasing pressure to meet global food security demands while simultaneously reducing environmental burdens. This review critically evaluates air emissions, greenhouse gas (GHG) contributions, water pollution, and solid waste generation a...

Seqout: metadata harmonisation for public genomic data discovery

Poster presented at Genomics India Conference 2026 (https://genomicsindia.co.in/) held in Bengaluru

Reversible Oxidation of a Nonathia[42]Nonaphyrin(1.1.0.1.1.0.1.1.0) to a 40π Dication Diradicaloid

Abstract A one-pot condensation of bithiophene with thiophene diol under acidic conditions yields 28π, 42π, and 56π expanded porphyrinoids. X-ray crystallographic studies revealed a planar topology for both 28π and 42π macrocycles. Spectroscopic and quantum chemical calculations...

Machine learning for burning rate prediction of solid propellants

The burn rate is a key performance parameter in the development of new propellant formulations. However, its experimental determination is highly time- and resource-intensive, which demands faster, more economical predictive methods prior to experimentation. In this study, a mach...

Mechanically Superior HDPE Composites Reinforced with Alkali-Treated Saccharum Munja Fibers for Sustainable Engineering Applications

Abstract The global transition towards sustainable materials demands high-performance composites derived from naturally abundant resources. Although natural fiber-reinforced polymers have gained attention, the development of scalable, industry-ready alternatives to synthetic fill...

A combined experimental and numerical study of heat losses in upward-facing helical cavity receivers

Cavity receivers improve the thermal efficiency of concentrated solar systems because the small aperture traps reflected sunlight and limits re-radiation and convective losses from the absorber. This study examines a small upward-facing helical cavity receiver, with an aperture d...

Inadequacy of Two-Drop Studies in Explaining Chaining in Emulsion Systems under AC Electric Fields

Abstract Efficient dewatering of crude oil emulsions is often hindered by droplet chaining, yet the mechanisms responsible for the strong tendency to chain at low electric capillary numbers (Cae ≤ 0.02) remain unclear. Here, we combine high-speed microscopy and numerical simulati...

Classification and dilation for q-commuting 2 × 2 scalar matrices

A tuple T _ = ( T 1 , … , T k ) of operators on a Hilbert space H is said to be q-commuting with ‖ q ‖ = 1 or simply q - commuting if there is a family of scalars q = { q i j ∈ C : | q i j | = 1 , q i j = q j i − 1 , 1 ≤ i < j ≤ k } such that T i T j = q i j T j T i for 1 ≤ i < j...

Inverse Design of the Topology–Bandwidth Trade-Off in Valley Photonic Crystals

Abstract Valley photonic crystals provide a route to broadband domain-wall guiding, but increasing the bulk gap can delocalize Berry curvature and reduce the nonquantized valley-Chern number. We introduce a mixed-integer particle-swarm framework that searches polygonal VPC unit c...

Seismic risk of aging asymmetric reinforced concrete buildings

Reinforced concrete (RC) buildings located in corrosion-laden aggressive environments experience progressive deterioration over time that adversely affects their strength, stiffness, and ductility. While the interaction between corrosion and earthquake has been investigated in th...

Stability Assessment of Landslides under Coupling Action of Rainfall and Earthquake

Abstract Separated analyses are widely used to evaluate the stability of slopes after rainfall and earthquakes. However, the combined impact of rainfall infiltration and earthquake shaking on slope stability remains insufficiently studied. Therefore, a unique closed-form analytic...

A Long-Term Procurement Framework for Repeated Public Utility Services: A Model for Timely, Competitive and Quality-Oriented Procurement

Public services and essential utilities require continuous maintenance, repairs, upgrades and service support. These requirements frequently involve repeated procurement of similar materials, components, equipment and services. In public procurement, each requirement must comply...
