Intellectual architecture of sustainable entrepreneurial ecosystems - a bibliometric review

Purpose Despite growing scholarly attention, research on sustainability and Entrepreneurial Ecosystems (EEs) remains theoretically, empirically and methodologically dispersed. Recent reviews have mapped the research but not diagnosed why the field is disconnected. This study aims...

Modeling the potential of green roofs and improved green roof systems for urban flood mitigation in Chandigarh, India

Rapid urbanization and increasing rainfall extremes have aggravated urban flooding, which calls for sustainable stormwater management strategies. Green roof systems (GRS) are acknowledged as effective nature-based solutions, yet their hydrological performance under monsoon-domina...

Machine Learning Framework with Posthoc Explainability for Predicting the Strength of Mechanochemically Activated Geopolymer Paste

Abstract Geopolymers offer a low-carbon alternative to ordinary portland cement (OPC); yet their industrial adoption is hindered by complex multivariate design spaces exceeding 10 6 possible formulations and reliance on empirical optimization. This study integrates mechanochemica...

Four-port MIMO cylindrical dielectric resonator antenna with FSS corner reflectors for gain and pattern diversity enhancement

Abstract This paper presents a four-port multiple-input multiple-output (MIMO) cylindrical dielectric resonator antenna (CDRA) with frequency-selective surface (FSS)-backed corner reflectors at 5.1 GHz to enhance performance. First, the single-port CDRA is investigated, and a mon...

Enhanced prediction of monthly reference evapotranspiration by optimizing SVR with the bagging algorithm in Indian Punjab

In this study, support vector regression (SVR) was enhanced with the Bagging (B-SVR) algorithm for monthly ET0 prediction at Ludhiana and Faridkot stations. The three different scenarios (S1, S2, and S3) were developed to predict monthly ET0 at study locations. The outcomes of th...

Magnetically enhanced water splitting reaction using nickel-Fe3O4 composite electrodes

We describe a simple electrodeposition method for creating a thin layer of Nickel-Fe 3 O 4 (Ni-Fe 3 O 4 ). The resulting thin film showed notable electrocatalytic activity for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in an alkaline media. In order...
