Normalized complex logistic wavelets: Fourier transforms and generating functions

We introduce a family of complex logistic mother wavelets generated by higher-order derivatives of an analytically shifted logistic function. Explicit closed-form expressions are obtained for the Fourier transforms of all derivatives, while the higher-order derivatives themselves...

A roadmap for standardization of serum albumin measurements

Abstract Albumin measurements in serum have important diagnostic and prognostic roles. However, non-standardized measurement procedures are still used in medical laboratories. An agreed approach for the implementation of metrological traceability to the International System of Un...

Tame Symmetric Algebras of Period Four with Small Gabriel Quivers

The tame symmetric algebras of period four, TSP4 algebras for short, form an important class of algebras, with interesting connections to various branches of modern algebra. The study of this class has been recently developed in two major directions. The first embraces new classe...

Model 1b analytical performance specifications – report on the Prague 2025 workshop

diagnostic medical devices (IVD MD) meet regulatory and quality standards before market release; for external quality assurance assessments; for quality control, monitoring reagent lot-to-lot variability, and allowing preanalytical variation assessments in labs; and for guiding p...

Symmetry-AdaptedRelaxation Theory (SART): VariationalEmbedding for Convergent Infinite-Order Induction without Overpolarization

Abstract The induction part of intermolecular interaction energy describes the effect of the mutual polarization of subsystems. Low-order induction effects can be reasonably described by symmetry-adapted perturbation theory (SAPT), but the capture of important higher-order polari...

Circulating PDIA4, MMP-2, MMP-9, and Claudin-2 in Vitamin D-Deficient Patients with Brain Tumors: An Exploratory Clinical Pilot Study

Background/Objectives: Extracellular matrix remodeling, cellular stress responses, and blood–brain/blood–tumor barrier-related alterations are important processes involved in brain tumor biology. This exploratory cross-sectional pilot study evaluated circulating circulating prote...

The genome sequence of the muscid fly, Hydrotaea similis Meade, 1887 (Diptera: Muscidae)

<ns5:p> We present a genome assembly from an individual female <ns5:italic>Hydrotaea similis</ns5:italic> (muscid fly; Arthropoda; Insecta; Diptera; Muscidae). The assembly contains two haplotypes with total lengths of 884.66 megabases and 852.78 megabases. Most of haplotype 1 (9...

The role of visual complexity and image authorship in shaping aesthetic experience: A comparison of original and artificial intelligence-modified art

In this project, we investigate how visual complexity and the authorship of artworks, whether created by a human or modified by artificial intelligence, affect viewers’ aesthetic experience. Additionally, we examine how these factors influence participants’ evaluations of how bea...

Allism: The Absolute All, Subjectivization, and Fulfilment

Allism begins with a simple metaphysical claim: reality has no exterior. The Absolute All is not a container filled with independently constituted things. It is the whole field of actuality, coherent possibility, relation, perspective, experience, and whatever can be experienced....

Death Anxiety in the Association Between Exposure-Related Burden of Patient Death and Occupational Burnout Among Healthcare Professionals: A Cross-Sectional Study

Background/Objectives: Occupational burnout remains a major concern among healthcare professionals and is closely linked to chronic workplace stress. Exposure to patient death may represent a death-related psychosocial occupational burden that is emotionally and existentially dem...

From prediction to practice: Barriers to implementing artificial intelligence in blood inventory management and transfusion support

BACKGROUND: Artificial intelligence (AI) is increasingly applied to blood-demand forecasting, donor management, inventory optimisation, wastage reduction and transfusion-related decision support; however, routine implementation remains limited. OBJECTIVES: To review current appli...
