Hybrid water security governance after conflict in South Sudan
This paper examines the hybrid institutional arrangements governing water security in post-conflict South Sudan. Based on a qualitative comparative case study of two sub-national states, it analyses how formal state agencies, customary authorities, and non-governmental organisati...

Safe Opponent Exploitation in Colonel Blotto: Where the Gifts Are, and What They Are Worth
We study safe opponent exploitation in discrete Colonel Blotto games with heterogeneous battlefield values. We investigate the characterization of gifts: pure opponent allocations which are not the best response to at least one equilibrium strategy and hence can be exploited with...

Assessment practices in school psychology are increasingly shaped by demands for evidence‑based practice alongside calls for culturally responsive and context‑sensitive approaches. Although observation is widely used in practice, it is often marginalized within research and evalu...

Repair in the Circular Economy: From Fragmented Practices to Strategic Repair Capability
ABSTRACT Repair is central to the circular economy, yet research remains fragmented across product design, consumer behaviour, business models, community initiatives and policy, limiting understanding of how these dimensions interact to enable repair at scale. This study systemat...

Probing the Conformational Behavior of a Seven Hetero-Spin Supramolecule
Abstract The synthesis and crystal structure of a 7-spin supramolecular poly-rotaxane is reported. The [4]rotaxane structure involves a trigonal thread centred on a {CrNi2} core, with each of the three arms terminated by Cu(II) centres and bearing a {Cr7Ni} metallocycle. The macr...

Background/Objectives: Lateral compression type 1 (LC-1) injuries range from stable patterns to injuries whose instability is not evident on initial imaging. How published studies define the criteria for operative fixation has not been characterized. Methods: We systematically re...

Target Color Contrast and Eccentricity in Visual Search: Implications for Control Panel Design
Control panel and monitoring interfaces require operators to perform visual search while assessing system status. This study examined how Target Color Contrast and Target Eccentricity, operationalizing specific visual and spatial aspects associated with the Salience and Effort co...

We study the diffusion and shear viscosity coefficients of hot isospin asymmetric strange hadronic matter. The effects due to the baryon density, isospin, strangeness, and temperature on the nucleons and hyperons are studied within a chiral SU(3) model. The medium modifications o...

Scalable and Personalized Oral Assessments Using Voice AI
When written work no longer shows who did the thinking, voice AI can bring back the oral exam at scale.
- Climate & EnvironmentOpen access
Abstract. Data-driven artificial intelligence (AI) weather models are increasingly positioned as alternatives or complements to physics-based numerical weather prediction (NWP) systems, yet systematic model evaluation studies that compare both paradigms under controlled experimen...

The Bayesian Nagaoka--Hayashi (NH) bound is a semidefinite lower bound on the Bayes risk of multiparameter estimation, tighter than the Bayesian symmertic logarithmic derivative (SLD) Cramér--Rao bounds, and whether it can be attained is an open problem. We study the single-shot...

Monte Carlo solution of the Kondo model
The Kondo model is a paradigmatic quantum impurity problem realized in a wide variety of experimental platforms and central to the study of strongly correlated electrons. We introduce a discrete model that exactly reproduces the multichannel Kondo model and demonstrate that it ca...

On integrable structures on non–compact boundaries in three–dimensional gravity
We study three-dimensional Einstein gravity with negative cosmological constant on non-compact spatial boundaries within the Chern-Simons formulation. Using an exact fluid/gravity correspondence, we derive a closed radial flow equation for the quasi-local stress tensor and show t...

Uncertainty relations for opponency of perceived chromatic states
Abstract In a previous work, the theoretical existence of uncertainty relations governing chromatic opponency for general chromatic states within a quantum information-based model of color perception has been established. In the present study, we extend this result by deriving un...

It has been observed that the Universe is permeated by the cosmic photon background, ranging from radio waves to gamma rays. We investigate the conversion of the photon background into gravitons in the presence of background magnetic fields in the Milky Way Galaxy and in blazar j...

Persistence properties of a phase-ordering system with competing dynamics
We investigate the persistence properties during phase ordering in the two-dimensional ($d=2$) Ising model evolving under competing nonconserved spin-flip and conserved spin-exchange dynamics by means of Monte Carlo simulations at zero temperature. We examine three distinct persi...
- Materials & EnergyOpen access
Abstract NiTi shape memory alloys (SMAs) exhibit outstanding pseudoelasticity, yet the strongly first-order nature of their martensitic transformations (MTs) produces autocatalytic strain avalanches and large hysteresis that limit controllability and energy efficiency. Recent exp...

Adiabatic dressing of quantum enhanced Markov chains
Quantum-enhanced Markov chain Monte Carlo, a hybrid quantum-classical algorithm in which configurations are proposed by a quantum proposer and accepted or rejected by a classical algorithm, has been introduced as a possible method for robust quantum speedup. Previous work has ide...

Abstract. As climate change increases frequency and intensity of hot extremes, understanding how elevated temperatures influence surface ozone (O3) across different chemical regimes is critical. We combine observations from summer 2022 in the Yangtze River Delta (YRD) with target...

Universal Hamiltonian control in a planar trimon circuit
Multimode circuits provide an avenue for flexible control of single and multi-qubit gates. In this work we implement a multimode circuit known as a trimon integrated in a planar geometry. The trimon features three transmon-like modes with strong all-to-all $ZZ$ coupling. We demon...
