In this work we search for boundedness results for operators related to the semigroup generated by the degenerate Schrödinger operator Lu=−1ωdivA⋅∇u+Vu, where ω is a weight, A is a matrix depending on x and sati...

Abstract Colostrum is the first mammary secretion produced after parturition and represents a biologically active fluid essential for neonatal survival, immune maturation, and early growth. Despite its importance, breed-...

Purple carrots (Daucus carota ssp. sativus var. atrorubens Alef.) accumulate anthocyanins in their roots, petioles and other plant parts. These flavonoid pigments represent an excellent dietary source of antioxidant and ...

Polymer composites of epoxy resin and Nb2O5 doped BaTiO3 were prepared in the form of film (thickness 30-300 μm) using a dipping technique. Samples containing various amounts of ceramic filler were examined by thermal a...

A near-Heyting algebra is a join-semilattice with a greatest element such that every principal upset is a Heyting algebra. We will present several characterizations of the concept of near-Heyting algebra. We will show th...

Abstract Northern Ghana faces acute climate vulnerabilities, yet adaptation pathways remain fragmented and poorly synthesized. This study systematically reviewed 15 peer-reviewed literature covering the Savannah, Upper E...

Abstract Solar-powered electric-vehicle (EV) charging in tropical, PV-rich regions such as Uganda faces coupled stressors from high ambient temperature and intermittent solar irradiance, which can destabilize conventiona...

Abstract The purpose of this study is to provide a more comprehensive and updated analysis of how green finance enabled by financial technology (Fintech) and digital innovation, contributes to sustainability in economic ...

Among the South American Arid Diagonal (SAAD), the Argentine Arid Diagonal (AAD) constitutes an area with low precipitations (less than 500 mm) and extends from the north of the country (on the border with Bolivia), to P...

Lean duplex stainless steels (LDSS) emerged as a competitive duplex stainless steels (DSS) where Ni is partially replaced by lower cost alloying elements such as Mn and N. However, to date there has been little to no inf...

Abstract IgA nephropathy (IgAN), the most common primary glomerulonephritis worldwide, is characterized by mesangial IgA deposition, which triggers complement activation, primarily through the alternative pathway. While ...

Drier conditions have been observed in Northern Patagonia, Argentina, in the last decades, affecting the pastoralism production system. In this context, two laws were promoted to foster goat and sheep production. This re...

A set of coupled Brownian motors—resulting from a noise-induced phase transition generated through an entropic mechanism, and formerly studied in mean-field approximation—is numerically integrated by Heun’s method....

Abstract This study reveals the impact of digital maturities on customer relationship management (CRM) performance in automotive industries. A fuzzy comprehensive evaluation (FCE) approach is employed to evaluate CRM per...

The deactivation of the H3PW12O40 (HPW) catalyst supported on TiO2 used in the isomerization reaction of α-pinene and its regeneration were studied. The regeneration of the deactivated catalyst was carried out with an a...

Abstract The photocatalytic efficiency of pristine titanium dioxide nanoparticles (TiO2 NPs) remains suboptimal due to its poor visible light absorption and rapid charge carrier recombination, necessitating fine structu...

Agroecosystems are usually polluted with a wide variety of contaminants with pesticides being very frequently detected. Endosulfan, an organochlorine pesticide, has been shown to cause both lethal and sublethal effects o...

Background and aimsThe ability of plant microbial symbionts to enhance hosts´ fitness depends on the abiotic and biotic context, including the presence of co-existing symbionts. We studied how the presence of arbuscular...

Abstract Over the past two decades, agricultural exports in Southeast Asia have surged due to trade liberalization and rising global food demand. This study examines the environmental impacts of agricultural exports in A...

Abstract Therapeutic resistance remains a major cause of treatment failure and disease recurrence across cancer types, considerably limiting the long-term efficacy of chemotherapies, targeted therapies, and immunotherapi...

Communicating climate change projections to diverse stakeholders and addressing their concerns is crucial for fostering effective climate adaptation. This paper explores the use of storyline projections as an intermediat...

Generalized dualities had an intriguing incursion into Double Field Theory (DFT) in terms of local O(d, d) transformations. We review this idea and use the higher derivative formulation of DFT to compute the first order ...

Clavibacter michiganensis subsp. michiganensis causes bacterial wilt and canker in tomato. A detailed account of pathogen effects on growth and water parameters of affected plants is lacking. Besides, the long latent per...
