Scalable Membrane-Based Lithium-Ion Sieve Sorbent for Selective Lithium Extraction from Brines

Abstract The escalating global demand for lithium, driven by the rapid growth of production of electric vehicles and portable electronics, requires the development of selective and scalable extraction technologies capable of recovering lithium from complex liquid resources such a...

On the short-wavelength stability and the Kelvin–Helmholtz instability of some explicit solutions to the two-layer nonlinear three-dimensional water wave problem

Abstract This study is concerned with explicit solutions in the Eulerian framework to the three-dimensional nonlinear Euler equations with a free surface and an interface. Starting with a depth-dependent density, continuous within the fluid domain, except across the interface, we...

Arithmetic properties of the Taylor coefficients of differentially algebraic power series

Let f = ∑ n = 0 ∞ f n x n ∈ ℚ ¯ 〚 x 〛 be a solution of an algebraic differential equation Q ( x , y ( x ) , ⋯ , y ( k ) ( x ) ) = 0 , where Q is a multivariate polynomial with coefficients in ℚ ¯ . The sequence ( f n ) n ≥ 0 satisfies a non-linear recurrence, whose expression i...

The WoKaS-Iso database: workflow for a global compilation of oxygen-18 and deuterium records in karst springs and cave drip water for enhanced understanding of karst systems

For analysing karst hydrogeological systems, observations of karst springs and cave drips are considered indispensable. In addition to hydrometric observations, knowing the oxygen and hydrogen stable isotope ratios has improved the understanding of vadose zone and aquifer dynamic...

Competition between vacancy creation and filling in defect-engineering of hBN

Abstract Hexagonal boron nitride (hBN) has recently become the focus of intense research as a material that can host quantum emitters. It is known that such emission is related to point defects, but in order to conclusively correlate specific defects to their spectra, having cont...

On large-scale wind-drift ocean currents: An asymptotic approach in spherical coordinates

Starting from the Navier–Stokes equations in rotating spherical coordinates with depth-varying density and eddy viscosity, we derive an asymptotic model describing non-equatorial wind-generated ocean drift currents. Our approach allows for large-scale flows that cannot be capture...

Constraints on the Loss of Hydroperoxymethyl Thioformate (HPMTF) to Marine Clouds Using Aircraft Observations

Abstract The photochemical oxidation of dimethyl sulfide (DMS) by the hydroxyl radical (OH) contributes to the production and growth of particles and cloud condensation nuclei in the marine boundary layer (MBL). DMS oxidized by OH can go on to form a stable intermediate, hydroper...

Goshawk Genomics: Genome Wide Single Nucleotide Polymorphisms ( SNPs ) Confirm Species Status of Astur gentilis and Astur atricapillus

ABSTRACT The Astur [ gentilis ] superspecies comprising five species has a long record of taxonomic debate. Recent evidence based on mitochondrial data, limited genomic data and bioacoustics suggested a Nearctic‐Palearctic split of the former Holarctic species Astur gentilis , le...

On convolved weight matrices and local solvability with controlled loss of regularity

Abstract We introduce the convolution between abstractly given anisotropic weight matrices and investigate properties of this new construction. Further, we apply the knowledge to the particular but interesting case when the (isotropic) matrices are associated with weight function...

Digital Agency Tools: A Way to Buffer the Negative Effects of Excessive Phone Use?

In times of ubiquitous smartphone use, most users adopt one or more self-imposed rules regarding their device usage, also known as voluntary digital disconnection. Drawing on the Integrative Model of Mobile Media Use and Need Experiences (IM³UNE), this study provides empirical ev...

Generalized cluster states in 2+1d: Non-invertible symmetries, interfaces, and parameterized families

We construct 2+1-dimensional lattice models of symmetry-protected topological (SPT) phases with non-invertible symmetries and investigate their properties using tensor networks. These models, which we refer to as generalized cluster models, are constructed by gauging a subgroup s...

Crystallization in the Winterbottom Shape and Sharp Fluctuation Laws

Abstract We address finite crystallization in two dimensions in the presence of a flat crystalline substrate. Particles interact through short-range two- and three-body potentials favoring local square-lattice arrangements. An additional interaction term of relative strength $$\b...

Chemical Structure Controls Soil Biotransformation Kinetics of Bacillus Lipopeptide Biopesticides

Abstract Bacillus lipopeptides (surfactins, iturins, and fengycins) are an emerging class of biopesticides. However, their fate in agricultural soils, and specifically how variations in the chemical structure such as alkyl chain length, amino acid sequence, and cyclization affect...

No detectable association of APOE ε4 with spatial navigation and broader cognition in healthy young adults

Abstract Alzheimer’s disease (AD) causes progressive memory loss and disorientation. It is preceded by a prolonged preclinical phase marked by pathological changes in medial temporal lobe regions involved in spatial navigation. Spatial navigation tasks have been proposed for earl...

Fault Slip Reversals Preceded the Intraplate 2021 Earthquake Series in the Vienna Basin (Central Europe)

Abstract Fault‐slip reversals indicate transient stress changes and may illuminate earthquake preparation processes. Here we present high‐resolution observations of sub‐millimetric creep and slip reversals on the Altaquelle Fault, a Quaternary normal fault in the southern Vienna...

Self‐control strategies to reduce meat consumption: An ecological momentary intervention

An increasing number of individuals aim to reduce their meat consumption, but implementing this is challenging. Self-control strategies could support this change; however, their effectiveness remains understudied. This study examines whether providing self-control strategies supp...

Application to Dalhousie University September 2026 : A Quick Note About Information System Classifications

We have started an Application into The Dalhousie University English Program. We notice for the first time a very intelligent information system. Some documents that we did save in our Google Drive Account [but not published elsewhere*] have contributive value in the system. As f...
