In this article we apply signal detection theory to qualitatively unify the intensity justnoticable difference (JND) and masking data of Wegel and Lane (1924), Fletcher and Munson (1933 – 1938), Miller (1947), and Egan and Hake (1950). We do this by treating the loudness as the first moment, and the intensity JND as the second moment, of the random variable we call the single-trial loudness. Fr...

The present work explores the adaptive behavior of well-known ureolytic bacterial strain namely Sporosarcina pasteurii for microbial-induced calcite precipitation (MICP) under saline environment. MICP activity was observed up to 10% NaCl supplementation and confirmed by several characterization techniques viz. scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analys...

In earlier work, the second named author described how one may extract Darmonstyle L -invariants from modular forms on Shimura curves that are special at p. In this paper, we show that these L -invariants are preserved by the Jacquet–Langlands correspondence. As a consequence, we prove the second named author’s period conjecture in the case where the base field is Q. As a further application of...

We construct three-dimensional families of hyperelliptic curves of genus 6, 12, and 14, two-dimensional families of hyperelliptic curves of genus 3, 6, 7, 10, 20, and 30, and one-dimensional families of hyperelliptic curves of genus 5, 10 and 15, all of which are equipped with an an explicit isogeny from their Jacobian to another hyperelliptic Jacobian. We show that the Jacobians are genericall...

In recent years, oil spills and leakages have often occurred during exploration, transportation, handling, usage, processing, causing serious global environmental problems. Microbially-induced carbonate precipitation (MICP) is an emerging green, environmentally friendly, sustainable technology that has proven to be a promising alternative for soil stabilisation. This paper provides comparison b...

After exposure to high temperatures, the mechanical properties and durability of concrete structures are significantly reduced, effective measures must be taken for reinforcement repair. High-temperature damage manifests as looseness, spalling, cracks, which suitable microbial-induced carbonate precipitation. When repairing high-temperature with precipitation (MICP), calcium source is an import...

It is difficult to collect and characterise well-preserved samples of weakly-cemented granular rocks as conventional sampling techniques often result in destruction the cementation. An alternative approach prepare synthetic geomaterials match required specifications. This paper introduces microbially induced carbonate precipitation (MICP) a method reliably deliver artificially cemented specimen...

Microbially induced calcium carbonate precipitation (MICP) is an innovative biocementation technique that facilitates the formation of within a pore network. Initially gaining prominence in field geotechnical engineering, MICP has attracted significant attention since its inception (the last three decades) and expanded reach across various engineering disciplines. Examples include rock mechanic...
