System dynamics simulation of the thermal dynamic processes in nuclear power plants

open access: yesNuclear Engineering and Technology, 2019
A nuclear power plant (NPP) is a highly complex system-of-systems as manifested through its internal systems interdependence. The negative impact of such interdependence was demonstrated through the 2011 Fukushima Daiichi nuclear disaster. As such, there

A Note on Cycles in Locally Hamiltonian and Locally Hamilton-Connected Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2020
Let đ’« be a property of a graph. A graph G is said to be locally đ’«, if the subgraph induced by the open neighbourhood of every vertex in G has property đ’«. Ryjáček conjectures that every connected, locally connected graph is weakly pancyclic.

Enumerating all Hamilton Cycles and Bounding the Number of Hamilton Cycles in 3-Regular Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2011
We describe an algorithm which enumerates all Hamilton cycles of a given 3-regular $n$-vertex graph in time $O(1.276^{n})$, improving on Eppstein's previous bound. The resulting new upper bound of $O(1.276^{n})$ for the maximum number of Hamilton cycles in 3-regular $n$-vertex graphs gets close to the best known lower bound of $\Omega(1.259^{n})$.

APOE‐stratified Proteomic and Metabolomic Analysis Reveals Mitochondrial Dysfunction Inflammation and Lipid Dysregulation in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
A large‐scale multiomic dataset (proteomic and metabolomic) comprising 3,060 plasma samples were analyzed to identify proteins, metabolites, pathways, and protein‐associated drugs linked to Alzheimer’s Disease (AD) independently of apolipoprotein E (APOE). AD was associated with a distinct molecular signature that captures.

Deciphering and Targeting the Schwannoma‐Neuron‐Macrophage Crosstalk for the Treatment of Schwannomatosis and Associated Pain

open access: yesAdvanced Science, EarlyView.
We established patient‐derived SWN cell lines and orthotopic PDX models that recapitulate patient pain phenotypes, alongside a novel intravital DRG imaging platform to track macrophage infiltration and neuronal pain responses. Using these models, we define HMGB1–CCL2–IL‐6 signaling crosstalk driving pain and identify EGF signaling as a key regulator of

Energy Conditions for Hamiltonicity of Graphs

open access: yesDiscrete Dynamics in Nature and Society, 2014
Let G be an undirected simple graph of order n. Let A(G) be the adjacency matrix of G, and let ÎŒ1(G)≀Ό2(G)â‰€â‹Żâ‰€ÎŒn(G) be its eigenvalues. The energy of G is defined as ℰ(G)=∑i=1n‍|ÎŒi(G)|. Denote by GBPT a bipartite graph.

An update on the middle levels problem

open access: yes, 2006
The middle levels problem is to find a Hamilton cycle in the middle levels, M_{2k+1}, of the Hasse diagram of B_{2k+1} (the partially ordered set of subsets of a 2k+1-element set ordered by inclusion).

Machine Learning Discovery of Record‐Low Lattice Thermal Conductivity in Double Perovskites

open access: yesAdvanced Science, EarlyView.
 A deep learning interatomic potential is introduced to predict forces for computing phonon properties and thermal transport behavior in double perovskites. Screening 9,709 compounds identifies 1,597 stable materials, and Boltzmann transport calculations including both three and four‐phonon scattering suggests a record‐low lattice thermal conductivity ...

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

open access: yesAdvanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...
