Demand and Equilibrium Price of Health Care: A Structural Equation Approach

open access: yesFoundations of Management
In this article, we propose a new approach to estimating health-care demand. The aim of this paper is to determine the production costs of health care from the demand function of care.

Assessing the population structure of Plagioscion squamosissimus (Teleostei, Perciformes, Sciaenidae) from the São Francisco River, Bahia, Brazil, using body morphology and otolith shape signatures

open access: yesJournal of Fish Biology, EarlyView.
Abstract The south American silver croaker, Plagioscion squamosissimus, holds significant importance for the artisanal fisheries in the sub‐middle and lower courses of the São Francisco River, located in northeastern Brazil. To investigate the population structure of this species along its longitudinal profile, a total of 150 individuals (50 fish per ...

Iterative Approximate Solutions of Kinetic Equations for Reversible Enzyme Reactions [PDF]

open access: yes, 2013
We study kinetic models of reversible enzyme reactions and compare two techniques for analytic approximate solutions of the model. Analytic approximate solutions of non-linear reaction equations for reversible enzyme reactions are calculated using the ...

Observations of Fine‐Scale Structures During the Pause Period of Positive Leader Discharge

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract In positive leader discharge, the channel evolution process during pause period significantly impacts the subsequent discharge behavior accompanied by sudden elongation and intense reillumination of the discharge channel. The discontinuous discharge phenomenon is widely observed in the intermittent positive leader of natural lightning and ...

Construction of dynamical quadratic algebras

open access: yes, 2003
We propose a dynamical extension of the quantum quadratic exchange algebras introduced by Freidel and Maillet. It admits two distinct fusion structures.

Selective Promotion of Retinal Organoid Attachment and Differentiation by Amine‐ and Hydroxyl‐Modified Surfaces

open access: yesAdvanced NanoBiomed Research, Volume 6, Issue 2, February 2026.
Engineered biomaterial interfaces critically control retinal organoid development. This study examines how surface modifications (amine, hydroxyl, phenyl, and methyl groups) dictate organoid response. Hydrophilic surfaces markedly increase migration and foster retinal ganglion cell differentiation.

Weak Decays of Doubly Heavy Baryons: Multi-body Decay Channels

open access: yes, 2017
The newly-discovered $\Xi_{cc}^{++}$ decays into the $ \Lambda_{c}^+ K^-\pi^+\pi^+$, but the experimental data has indicated that this decay is not saturated by any two-body intermediate state.

π‐Expanded BODIPYs and Related Analogs as Long‐Wavelength Absorbing Photosensitizers for Green Energy Conversion

open access: yesChemNanoMat, Volume 12, Issue 1, January 2026.
The versatile modification capability of BODIPYs and the related analogs with excellent photophysical properties allows chemists to propose photosensitizers applicable to energy‐related materials. This review mainly focuses on the π‐extension strategy for achieving sunlight‐harvesting capabilities. The insights and challenges for future research on red

The case for cash

open access: yesLatin American Journal of Central Banking, 2020
Cash is an extremely useful social contrivance. Kenneth Rogoff, who calls for phasing-out high denomination cash over time, recently discussed two possible drawbacks of high-denomination cash: the extensive use of high-denomination cash in crime and in ...

Highly ordered micro‐sphere films with finely tunable mono‐ to multi‐layer for optical anti‐counterfeiting

open access: yesDroplet, Volume 5, Issue 1, January 2026.
A fibrous liquid bridge strategy was developed to fabricate highly ordered micro‐sphere films with finely tunable mono‐ to multiple layer. This method enables the formation of a homogeneous thin liquid film with controllable thickness, where liquid transfer and dewetting‐confined micro‐sphere assembly occur under dynamic equilibrium, resulting in well ...
