"This paper describes the basic set-up of a macroeconomic model disaggregated into 4 sectors. The purpose of the model is to analyze the structural effects of immigration policy. In a first section, the working of the model is illustrated by computing multipliers for various exogenous changes. In particular, the sensitivity of the multipliers with respect to the parameter values is discussed. The next section deals with the incorporation of the labour market and presents some simulation results based on theoretically plausible parameter values." The geographical focus is on Switzerland.

Diagnostic Decision-Making Variability Between Novice and Expert Optometrists for Glaucoma: Comparative Analysis to Inform AI System Design.
JMIR Med Inform

Department of Systems Design Engineering, Faculty of Engineering, University of Waterloo, Waterloo, ON, Canada.
Background: While expert optometrists tend to rely on a deep understanding of the disease and intuitive pattern recognition, those with less experience may depend more on extensive data, comparisons, and external guidance. Understanding these variations is important for developing artificial intelligence (AI) systems that can effectively support optometrists with varying degrees of experience and minimize decision inconsistencies.
Objective: The main objective of this study is to identify and analyze the variations in diagnostic decision-making approaches between novice and expert optometrists.

In this study, a distinctive multiple core-shell structure of Co nanoparticles inserted into N-doped carbon dodecahedron@Co hydroxide (Co/NCD@Co(OH)) was synthesized a spontaneous redox reaction between metallic Co and NO, ultimately materializing the fine dispersion and exposure of the active sites. The electronic interaction existing between the Co/NCD core and the Co(OH) shell brings a synergistic effect, conspicuously lessens the overpotential, and reinforces the yield-rate and faradaic efficiency of NH for electrochemical nitrate-ammonia conversion. This study underlines the spontaneous redox between the catalysts and substrate, rendering it as a synthetic strategy for designing genuine and well-dispersed active sites.

In this work, a theoretical approach is developed to investigate the structural properties of ionic microgels induced by a circularly polarized (CP) electric field. Following a similar study on chain formation in the presence of linearly polarized fields [T. Colla , , 2018, , 4321-4337], we propose an effective potential between microgels which incorporates the field-induced interactions a static, time averaged polarizing charge at the particle surface.

We introduce an effective field theory (EFT) for conformal impurity by considering a pair of transversely displaced impurities and integrating out modes with mass inversely proportional to the separation distance. This EFT captures the universal signature of the impurity seen by a heavy local operator. We focus on the case of conformal boundaries and derive universal formulas from this EFT for the boundary structure constants at high energy.

In recent years, the theoretical description of electrical noise and fluctuation-induced effects in electrolytes has gained renewed interest, enabled by stochastic field theories like stochastic density functional theory (SDFT). Such models, however, treat solvents implicitly, ignoring their generally polar nature. In the present study, starting from microscopic principles, we derive a fully explicit SDFT theory that applies to ions in a polar solvent.
