A three-stage route is proposed for the preparation of a covalent pullulan-beta-cyclodextrin conjugate through carboxymethylation of beta-cyclodextrin, EDC/NHS-mediated coupling with cysteamine, allylation of pullulan, and photoinitiated thiol-ene conjugation in a supercritical c...

Blowup above the exponent one third in viscous Katz-Pavlović dyadic models with small shell ratios
For the viscous Katz–Pavlović dyadic model with shell ratio Λ > 23/2, global regularity holds exactly for dissipation exponents α ≥ 1/3. We prove that this threshold is not universal: for Λ = 6/5, 13/10, 3/2, 17/10 and 9/5, suitable nonnegative finitely supported data lose regula...

E8 Lattice Quantized Harmonic Resonance Mapping (LQHRM) — E8 Intelligence Research
The 240 root vectors of the E8 lattice act as discrete harmonic nodes that transform continuous error signals into quantized frequency states. When the 132Hz base frequency encounters the lattice's 8-dimensional symmetry, it undergoes a decomposition into 8 orthogonal sub-frequen...

For a one-dimensional time-fractional diffusion-wave equation, we investigate joint recovery of its fractional order and the initial velocity from measurements taken at one interior point. Uniqueness is proved through analytic continuation, Laplace transforms, an integral mean va...

Abstract Variable-diameter CFBs have been receiving increasing attention due to its synergistic regulation of solid holdup, contact efficiency, and residence time. Nevertheless, the influence of particle property on the complex gas–solid hydrodynamics remains poorly understood. T...

Exact Hausdorff measure of SLE boundary contacts
The dimension of a random fractal specifies its scaling exponent; a finite, nonzero measure requires a finer calibration. We determine this calibration for the boundary contacts of chordal SLEκ, 4 < κ < 8. With δ = 2 − 8/κ and β = 8/κ − 1, the exact Hausdorff gauge is h(r) = rδ[l...

Public speaking anxiety (PSA) represents a significant challenge, with a notable impact on the development of technical-scientific and communication skills. Based on a quantitative, cross-sectional design, the present study aims to carry out the cross-cultural adaptation of the P...

Assistive technology (AT) supports participation, independence, and well-being but also presents sustainability challenges for public healthcare organisations. This qualitative study explored sustainability tensions and paradoxes arising in AT decision-making. Semi-structured int...

Incarcerated postpartum individuals with opioid use disorder (OUD) are vulnerable to poor health outcomes, but care provision in custody for this population is variable. Addressing their distinct needs is crucial for improving correctional health care for postpartum people. In th...

Abstract A new synthetic strategy for the diastereo- and regioselective construction of furano-fused piperidine and piperidinone scaffolds is described. The method proceeds via a rhodium-catalyzed intramolecular carbonyl ylide cycloaddition between readily accessible N-allylated...

Near-rectangular P-positions in three-row Chomp with deficit at most six
We classify the losing positions (n,n,n-g) in three-row Chomp for every integer n>g and 1<=g<=6. There are exactly eight such positions. The proof combines a counting bound for the row at which a value becomes constant with a uniform bound obtained from Zeilberger's published low...

Tetrandrine (TET) is a bisbenzylisoquinoline alkaloid with promising anticancer activity, although its limited selectivity toward malignant over non-cancerous cells restricts its therapeutic potential. A series of mono- and bis-N-substituted tetrandrine derivatives was therefore...

Genomic inbreeding and selection signatures analyses in the Doberman Pinscher breed
The Doberman Pinscher population has undergone strong artificial selection for morphology and behavior, which can reduce genomic diversity and increase autozygosity. Here, we characterized the genome structure and identified selection signatures in Doberman Pinschers using comple...

BACKGROUND As the population of survivors of cancer grows and new information technologies become widespread in Hong Kong, survivors of cancer increasingly seek ongoing care and support information from large language models (LLMs). While these tools provide immediate conversatio...
