Implementation Efficiency and Sustainable Infrastructure Outcomes: Evidence from NDB-Funded Projects in China, India, and South Africa

This study examines the relative implementation efficiency under a specified input–output framework and documented sustainability outcomes of New Development Bank (NDB)-financed infrastructure projects in India, China, and South Africa. Data Envelopment Analysis (DEA) is applied...

Effect of Gallium Doping on the Oxygen Exchange Kinetics in La2SrFe2O7−δ Ruddlesden–Popper Phases

This study investigates the oxygen exchange kinetics between O2 and Ga-doped La2SrFe2O7−δ, focusing on the role of gallium substitution in modifying the surface exchange properties of materials. Two compositions, undoped La2SrFe2O7−δ and Ga-doped La2SrFe1.8Ga0.2O7−δ, were synthes...

Pyrazine-Based Chemosensors for Cation Detection

Pyrazine (1,4-diazine) and its annulated derivatives are promising platforms for colorimetric and fluorescent chemosensors of biologically and environmentally relevant metal cations, including Hg2+, Cu2+, Zn2+, Pb2+, Fe3+, Al3+, Co2+, Ni2+, Ag+ and Cr3+. Their sensing potential a...

Addendum: Magnetic field screening in hydrogen-rich high-temperature superconductors

In our paper 1 , we studied the magnetic response of H 3 S and LaH 10 superconductors to an applied magnetic field using Superconducting Quantum Interference Device (SQUID) magnetometry. Prof. Hirsch, in his Matters Arising entitled “On the Author Correction to “Magnetic field sc...

Development of new lead-free borate glasses: Experimental evaluation for the impact of BaO on radiation shielding properties of glasses

This study investigated advanced glass compositions for gamma-ray shielding consisting of (78-x) B 2 O 3 -8MgO-13ZnO-1Eu 2 O 3 -xBaO, x = 23, 26, 29, and 32 mol%. Attenuation coefficients were calculated experimentally and simulated. The results between the two methods are fairly...

Viscosity and Minimax Solutions for Path-Dependent Hamilton–Jacobi Equations in Infinite Dimensions and Related Differential Games

Abstract We establish new results for path-dependent Hamilton–Jacobi equations with nonlinear monotone, and coercive operators on Hilbert space, which were initially studied in Bayraktar and Keller [2]. Under more general assumptions than in the cited paper (and more general than...

Model for managing the launch of a digital game product based on marketing analytics

This article examines a model for managing the launch of a digital gaming product. This model is an analytical and managerial framework based on marketing analytics methods and aimed at ensuring the validity of management decisions during the product's commercialization process,...

Strategic directions for the development of the passenger car market in China

The Chinese passenger car market is one of the most dynamic and structurally complex automotive markets in the world, which leads to the need for a thorough analysis of the strategies of key market players in order to develop an effective model of strategic behavior of automakers...

Domain switching by femtosecond NIR laser irradiation in bulk of single-domain and polydomain SBN single crystals

We have studied features of the domain patterns formed under the action of femtosecond near-infrared laser irradiation in the bulk of strontium barium niobate Sr 0.61 Ba 0.39 Nb 2 O 6 single crystalline Z-cut plates in single-domain and polydomain states. The polydomain state rep...

Analysis of the Current Transformer Core Saturation Impact on the Operation of the Algorithm for Emergency Control of the Power System Mode

The operation of protection algorithms and emergency control of power system modes is based on processing information about voltage levels and currents flowing through network elements. To measure these quantities electromagnetic voltage and current transformers with a closed mag...

Particle-volume distribution for coagulation and fragmentation phenomena

An exact analytical solution to the unsteady Smoluchowski coagulation equation complicated by particle fragmentation is derived for constant coagulation and fragmentation kernels. The particle-volume and particle-radius distributions as well as the large-time asymptotics and stea...

ABTS •+ radical cation-based new potentiometric approach for the studying of antioxidant capacity

The potentiometric approach for the studying of total antioxidant capacity, based on the use of the cation radical of 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), is proposed. Conditions for non-enzymatic generation that enable the formation of a cation radical/reduced...

Decoding Innovation in Circular Economy: Investigating Policy Pathways for the European Union

The transition from a linear to a circular economy has become a strategic priority for achieving sustainable development, resource efficiency, and economic resilience. However, empirical evidence on the determinants of circular economy innovation (CEI) remains limited, particular...

Bis-Pyrene-Appended Polyvinyl Chloride: Mechanosynthesis and Nitro-Explosive Detection
