A framework for some distinguished series of orthogonal type modular forms [PDF]

open access: yes, 2016
In this thesis we consider modular forms of orthogonal type. We consider lattices which can be represented as an orthogonal sum of two integral hyperbolic planes anda negative definite even lattice.

129Xe Nuclear Magnetic Resonance Spectroscopy of Metal–Organic Frameworks

open access: yesAnalysis &Sensing, Volume 6, Issue 4, July 2026.
129Xe NMR spectroscopy is a powerful technique to study porous materials. Properties such as pore sizes, pore connectivity, and dynamic switching processes associated with adsorption can be investigated. With its inertness and highly polarizable electron cloud, Xe allows for sensitive monitoring of small changes in the surface chemistry of materials ...

Hunting Structural Demons in Digital Reticular Chemistry: Lessons From Metal‐Organic Frameworks

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 4, July 2026.
Digital reticular chemistry is haunted by “structural demons”, chemically invalid models lurking within massive experimental and hypothetical MOF databases. This mini‐review tracks where these anomalies enter the data pipeline, evaluate the modern computational arsenal used to detect them (from rule‐based algorithms to machine‐learning classifiers ...

Epilepsy: Epidemiology, Molecular Pathogenesis, and Clinical Management

open access: yesMedComm, Volume 7, Issue 7, July 2026.
Epilepsy is a heterogeneous and chronically evolving brain network disorder. This review integrates epidemiological burden, psychiatric comorbidities, and cyclic seizure patterns with multiscale pathogenic mechanisms, including ion‐channel dysfunction, synaptic transmission defects, neuroinflammation, metabolic and mitochondrial dysfunction, and ...

Discrete Series and Characters of the Component Group [PDF]

open access: yes, 2007
Suppose φ: WR → L G is an L-homomorphism. There is a close relationship between the L-packet associated to φ and characters the component group of the centralizer of φ.

Fundamentals of a mathematical theory of fuzzy sets [PDF]

open access: yes, 1965
summary:Fuzzy sets establish a mapping from the interval of values of a criterial function onto a system of subsets of a basic set. In the paper, a system of definitions and theorems is introduced, which is aimed at an adequate expression of this point ...

Scotty: lattice coincidences for macromolecular crystallographic phasing

open access: yesActa Crystallographica Section D, Volume 82, Issue 7, Page 813-823, July 2026.
Scotty is a tool that leverages Niggli‐cell matches to identify similar crystallographic lattices and perform phasing with difference Fourier methods.When a macromolecular crystal lattice targeted for study is closely related to a previously studied crystal lattice, phasing the target crystal by difference (fast‐)Fourier transform (DFFT) methods is ...

Engineering Extracellular Vesicles for Anti‐Aging Therapy: Mechanisms, Applications, and Perspectives

open access: yesAging Cell, Volume 25, Issue 7, July 2026.
This review systematically elucidates the multifactorial anti‐aging mechanisms of extracellular vesicles (EVs). By bridging fundamental biology with advanced bioengineering, scalable manufacturing, and clinical translation, it establishes a comprehensive framework for developing next‐generation EVs‐based precision nanotherapeutics to combat systemic ...

Fatigue Strength Analysis of a Cladded Steel Subjected to Tensile Predeformation

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2767-2779, July 2026.
ABSTRACT Cladded steels are a subset of layered metal composites in which a thin functional layer is bonded to a dissimilar substrate, thereby integrating the benefits of both constituent materials. However, the resulting heterogeneous properties of such layered metal composites collectively complicate deformation and fatigue behavior, making reliable ...

An elegant model of the geodesic flow on the modular surface

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract Caroline Series' [The modular surface and continued fractions, J. Lond. Math. Soc. (2), 31, no. 1, (1985), 69–80] gives a clear framework linking, in a deceptively simple way, the dynamics of the geodesic flow on the modular surface with the dynamics of the regular continued fraction, through a well‐chosen symbolic coding.
