Extraction of parameters of a stochastic integrate-and-fire model with adaptation from voltage recordings.

Integrate-and-fire models are an important class of phenomenological neuronal models that are frequently used in computational studies of single neural activity, population activity, and recurrent neural networks. If these models are used to understand and interpret electrophysiological data, it is important to reliably estimate the values of the model's parameters. However, there are no standard methods for the parameter estimation of Integrate-and-fire models.

Is Tumor Growth Influenced by the Bone Remodeling Process?

In this study, we develop a comprehensive model to investigate the intricate relationship between the bone remodeling process, tumor growth, and bone diseases such as multiple myeloma. By analyzing different scenarios within the Basic Multicellular Unit, we uncover the dynamic interplay between remodeling and tumor progression. The model developed developed in the paper are based on the well accepted Komarova's and Ayati's models for the bone remodeling process, then these models were modified to include the effects of the tumor growth.

Interplay Between Spinmerism and Spin-Orbit Coupling for a d2 Metal Ion in an Open-Shell Ligand Field.

Recent, theoretical studies have shown that placing a spin-crossover ion in a field of radical ligands can induce local superpositions of local spin states (see Ref.[1,2]). This phenomenon, termed spinmerism, raises questions about its stability when spin-orbit coupling is included.

Assessment of decreased ovarian reserve and systemic inflammatory markers.

Given the significance of investigating ovarian reserve in infertile women, the limitations of existing diagnostic tests, and the absence of similar studies in this area, the present study aimed to examine the relationship between systemic inflammatory markers in patients with diminished ovarian reserve referred to the fertility clinic of Alzahra Hospital in Rasht in the year 2023. This cross-sectional analytical study was conducted on 174 patients referred to the Alzahra Hospital fertility clinic in Rasht. Patients were divided into two categories based on their serum levels of anti-Müllerian hormone (AMH):AMH >1.

Effectiveness and Safety of the TRIO Optimal Health Management Program in Patients with Type 2 Diabetes Mellitus (T2DM) Initiating Basal Insulin Therapy: Real-World Study.

Background: Diabetes, a chronic disease necessitating long-term treatment and self-management, presents significant challenges for patients who spend most of their treatment time outside of hospitals. The potential of digital therapeutics for diabetes has garnered recognition from different organizations. Although some prior studies have demonstrated successful reductions in patients' blood glucose levels and body weight through digital diabetes programs, many studies were limited by including prediabetes patients, patients treated with mostly premixed insulin, or evaluating user engagement outcomes rather than clinical outcomes.

Effect of Alkali Source on Crystal Regulation and Ethanol Gas Sensing Properties of Nano-ZnO.

This study investigates the ethanol gas-sensing mechanisms of ZnO nanocrystals with distinct morphologies, synthesized via a hydrothermal method using various alkali sources. Significant differences in the gas-sensing performance and morphology of ZnO samples synthesized with ammonium carbonate (NaCO), hexamethylenetetramine (HMTA), ammonia solution (NH·HO), and sodium hydroxide (NaOH) were observed. ZnO were confirmed to be impurity-free through XRD analysis, and their morphological features were characterized by SEM.

Electrical polarization switching of perovskite polariton laser.

Optoelectronic and spinoptronic technologies benefit from flexible and tunable coherent light sources combining the best properties of nano- and material-engineering to achieve favorable properties such as chiral lasing and low threshold nonlinearities. In this work we demonstrate an electrically wavelength- and polarization-tunable room temperature polariton laser due to emerging photonic spin-orbit coupling. For this purpose, we design an optical cavity filled with both birefringent nematic liquid crystal and an inorganic perovskite.
