Oleoylethanolamide regulates intestinal stem cell activity and villus size via PPARα signaling pathway

open access: yesiMetaOmics, EarlyView.
First use of a natural swine model with lipid metabolism to directly link lipid differences to a quantifiable intestinal villus height phenotype. Identified the phospholipid‐derived oleoylethanolamide, rather than canonical fatty acids, as the endogenous primary ligand that activates peroxisome proliferator‐activated receptors α (PPARα) to enlarge ...

Dose‐dependent association of systemic comorbidities with periodontitis severity: A large population cross‐sectional study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background To examine whether the associations between periodontitis and multiple systemic conditions increase with increasing severity of periodontitis using a multi‐center electronic health record (EHR) repository. Methods A cross‐sectional analysis was conducted using EHR data from 9 dental schools in the United States.

New graph classes characterized by weak vertex separators and two-pairs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2017
A set of vertices whose deletion from a graph would increase the distance between two remaining vertices is called a weak vertex separator of the graph. Two vertices form a two-pair if all chordless paths between them have length .

Feedback vertex set on chordal bipartite graphs [PDF]

open access: yes
Let G=(A,B,E) be a bipartite graph with color classes A and B. The graph G is chordal bipartite if G has no induced cycle of length more than four. Let G=(V,E) be a graph. A feedback vertex set F is a set of vertices F subset V such that G-F is a forest.

Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

Forbidden subgraphs of TI-power graphs of finite groups

open access: yesOpen Mathematics
Given a finite group GG with identity ee, the TI-power graph (trivial intersection power graph) defined on GG, denoted by Γ(G)\Gamma \left(G), is an undirected graph with vertex set GG where distinct vertices aa and bb are adjacent if ⟨a⟩∩⟨b⟩={e}\langle ...

Early use of the reinforced concrete in the architecture of the Historicism in Austria–Hungary

open access: yesStructural Concrete, EarlyView.
Abstract The study examines the early incorporation of reinforced concrete in the architecture of Historicism in Austria–Hungary. Spanning the late 19th to early 20th centuries, the research illuminates the period's stylistic pluralism and the transformative impact of reinforced concrete.

Large‐scale tests of 50‐year‐old prestressed concrete bridge girders

open access: yesStructural Concrete, EarlyView.
Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...
