An Optimized Freeze‐Dry Multimodal Workflow for Sequential Micro‐CT Imaging, Histology, and Molecular Profiling: A Use Case in Human Liver Fibrosis

open access: yesAdvanced Science, EarlyView.
Optimized freeze‐drying and eosin staining deliver artifact‐free micro‐CT images of liver tissue at near‐histological detail, then hand the same specimen back for sectioning, staining, and sequencing. Fibrotic volume distinguishes normal liver from cirrhosis, while preserved RNA reveals inflammatory gene upregulation—one biopsy, three dimensions, and a

Jaw‐specific stem cell dynamics are associated with distinct enamel architecture in mouse incisors

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The continuously growing mouse incisor serves as a model for stem cell‐driven tooth renewal. Although mice possess maxillary and mandibular incisors, most studies have focused on the mandible. Potential differences in structure and renewal between these serially homologous organs remain insufficiently characterized.

The Histidine 382 Residue Influences the Thermal Stability and Binding Propensity of the E2 Domain of Amyloid Precursor Protein

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The E2 domain of amyloid precursor protein (APP_E2) plays a central role in the protein's function. We reinvestigate how the missense mutation, ΔH382L, affects the domain's thermal stability and ligand binding propensity through differential scanning fluorometry.

Interplay Between Oxidation State, Intervalence Charge Transfer Transitions and Electronic Conductivity in a Series of Ru‐Based Metal–Organic Frameworks

open access: yesSmall, EarlyView.
Ru‐based square‐grid metal–organic frameworks undergo dramatic conductivity enhancements after chemical oxidation. The mixed‐valent states exhibit the highest conductivity values, which correlate with the appearance of intervalence charge transfer bands.

Advance in One‐Pot Synthesis of Polymer‐Coated Nanogold: Au(III)–Monomer Redox Reaction Initiates Radical Polymerization and Produces a Potential Nanotag Platform

open access: yesSmall, EarlyView.
Gold nanoparticles are prepared simultaneously with the formation of a polymer, whose growth is initiated by direct interaction of Au(III) with a vinyl‐type monomer. Nanoparticles produce stable, bioorthogonal SERS signal originating from an isonitrile/carbene‐type functionality covalently anchored to the gold surface.

Distance magic labelings of graphs [PDF]

open access: yes, 2013
Razdaljno magično označevanje grafa je bijekcija f : V -> {1, 2,...,n}, z lastnostjo, da obstaja taka konstanta k, da za vsako vozlišče x grafa velja, f(x_1)+f(x_2)+...+f(x_j)= k, kjer je y_i (i = 1,...,j) iz odprte okolice vozlišča x.

Characterization of magic graphs [PDF]

open access: yes, 1978
summary:A graph is called magic (supermagic) if it admits a labelling of the edges by pairwise different (consecutive) positive integers such that the sum of the labels of the edges incident with a vertex is independent of the particular vertex.

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

open access: yessteel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Early‐Life Telomere Length Negatively Covaries With Brood Size and Father Age, and Predicts Long‐Term Survival in Male Barn Swallows (Hirundo rustica)

open access: yesIntegrative Zoology, EarlyView.
In barn swallows, nestlings raised in larger broods or by older social fathers have shorter telomeres, and those with longer telomeres tend to live longer, suggesting that early‐life conditions may shape individual lifespan through telomere dynamics. ABSTRACT Parental decisions on breeding, such as brood size and timing of reproduction, influence the ...

Group distance magic labeling of direct product of graphs

open access: yesArs Mathematica Contemporanea, 2014
A distance magic labeling of a graph of order \(n\) is a bijection from the vertex set to \(\{0,1,\dots,n-1\}\) such that the sum of neighbors of any vertex is the same. Magic labellings of graphs have been studied as a generalization of magic squares. A central question has been to identify which graphs admit such labelings.
