A New Implementation of Network GARCH Model for Stock Volatility and Co‐Volatility Forecasting

Journal of Forecasting, EarlyView.
ABSTRACT Volatility clustering and spillovers are key features of financial time series with many cross‐sectional assets. While network analysis links similar or correlated stocks and helps trace volatility spillovers, contemporary multivariate ARCH‐GARCH formulations struggle to represent structured network dependence and remain parsimonious.

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Pretreatment EBV‐DNA/TLG‐Based Risk Stratification Is Associated With Survival Outcomes in Nonmetastatic Nasopharyngeal Carcinoma: An Exploratory Study

International Journal of Cancer, EarlyView.
ABSTRACT Whether combining pretreatment plasma Epstein–Barr virus DNA (EBV‐DNA) with 18F‐FDG PET/CT‐derived total lesion glycolysis (TLG) improves prognostic stratification in nonmetastatic nasopharyngeal carcinoma (NPC) is unclear, particularly in nonendemic populations.

Wearable photovoltaic textiles: From device technologies to long‐term reliability

InfoScience, EarlyView.
Wearable photovoltaic textiles are highlighted as reliable energy sources that combine solar cell efficiency with hierarchical textile‐specific mechanical and environmental durability. Structural and encapsulation strategies, including planarization, neutral‐axis engineering, and advanced barrier designs, enable waterproofing, washability, UV shielding,

The Strong Nash‐Williams Orientation Theorem for Rayless Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT In 1960, Nash‐Williams proved his strong orientation theorem that every finite graph has an orientation in which the number of arc‐disjoint directed paths between any two vertices is at least half the number of undirected edge‐disjoint paths between them (rounded down).

On Graphs Which Have Locally Complete 2‐Edge‐colourings and Their Relationship to Proper Circular‐Arc Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT A 2‐edge‐coloured graph G $G$ is called locally complete if for each vertex v $v$, the vertices adjacent to v $v$ through edges of the same colour induce a complete subgraph in G $G$. Locally complete 2‐edge‐coloured graphs have nice properties, and there exists a polynomial algorithm to decide whether such a graph has an alternating ...

Mathematical Model of a Stepped Triple Circular-arc Gear

, 2014
[[abstract]]An imaginary rack cutter with stepped triple circular-arc tooth profile is presented. The concept of stepped triple circular-arc tooth comes from the standard Chinese double circular-arc tooth profile and involute tooth profile.

A Framework for Subgroup Dynamics Through the System Dynamics Lens: An Integrative Review of the Attribute and the Network Views

Journal of Organizational Behavior, EarlyView.
ABSTRACT Subgroups are dynamic entities evolving constantly in response to changing contexts and time. Although scholars from both the attribute and the network views have acknowledged that subgroups are inherently complex and fluid, research in these traditions has remained bifurcated, with limited efforts to integrate the two perspectives to more ...
