Rationale and design of the TRIC‐I‐HF‐DZHK24 (TRICuspid Intervention in Heart Failure) trial

open access: yesEuropean Journal of Heart Failure, EarlyView.
Study overview of the TRIC‐I‐HF‐DZHK24 trial. HF, heart failure; HFH, heart failure hospitalization; QoL, quality of life; RHC, right heart catheterization; TR, tricuspid regurgitation; TTVI, transcatheter tricuspid valve intervention. Abstract Aims Tricuspid regurgitation (TR) is a detrimental disease frequently diagnosed in patients with right‐sided ...

Aerodynamic enhancement of wind turbine blades through Peregrine falcon‐inspired surface designs

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract As global energy demands increase, enhancing renewable energy technologies, particularly wind turbines, is essential to meet sustainability goals. However, achieving higher efficiency remains challenging due to limitations in traditional blade designs. This study explores an innovative solution by applying biomimetic principles inspired by the

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.

Cross‐continental transmission and host adaptation of Mycobacterium tuberculosis in China unveiled by population history reconstruction and adaptive evolution signal detection

open access: yesiMetaOmics, EarlyView.
This study showed that four Mycobacterium tuberculosis complex (MTBC) sub‐lineages might be introduced into China 1000–400 years ago via Europe‐China dispersal routes, where they diversified into local clades, and later underwent population expansions that coincided with periods of climatic cooling and warfare.

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 .

Chordality Properties and Hyperbolicity on Graphs

open access: yesThe Electronic Journal of Combinatorics, 2016
Let $G$ be a graph with the usual shortest-path metric. A graph is $\delta$-hyperbolic if for every geodesic triangle $T$, any side of $T$ is contained in a $\delta$-neighborhood of the union of the other two sides. A graph is chordal if every induced cycle has at most three edges.

Connected graph searching in chordal graphs

open access: yesDiscrete Applied Mathematics, 2009
Graph searching was introduced by Parson [T. Parson, Pursuit-evasion in a graph, in: Theory and Applications of Graphs, in: Lecture Notes in Mathematics, Springer-Verlag, 1976, pp. 426--441]: given a “contaminated†graph G (e.g., a network containing a hostile intruder), the search number View the MathML source of the graph G is the minimum number ...

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 ...
