Dynamics of Bid-ask Spread Return and Volatility of the Chinese Stock Market

, 2011
Bid-ask spread is taken as an important measure of the financial market liquidity. In this article, we study the dynamics of the spread return and the spread volatility of four liquid stocks in the Chinese stock market, including the memory effect and ...

Exploratory Analysis of Sustainable Consumption and Production Factors in Services: Insights From Four Case Studies Using Interpretive Structural Modeling

Sustainable Development, EarlyView.
ABSTRACT This study investigates how 14 sustainable consumption and production (SCP) factors interact across four service categories—Mass Service, Professional Service, Service Factory, and Service Shop—using interpretive structural modeling (ISM). ISM enables the identification and hierarchical classification of interdependencies among SCP factors in ...

Quotient Complexities of Atoms of Regular Languages

, 2012
An atom of a regular language L with n (left) quotients is a non-empty intersection of uncomplemented or complemented quotients of L, where each of the n quotients appears in a term of the intersection.

Parallel DFA Architecture for Ultra High Throughput DFA-Based Pattern Matching

IEICE Transactions on Information and Systems, 2010
Multi-pattern matching is a key technique for implementing network security applications such as Network Intrusion Detection/Protection Systems (NIDS/NIPSes) where every packet is inspected against tens of thousands of predefined attack signatures written in regular expressions (regexes). To this end, Deterministic Finite Automaton (DFA) is widely used

Novel Surgical Strategy System for Juvenile Nasopharyngeal Angiofibroma: A Focus on Feeding Artery Management

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objectives For intraoperative bleeding control in patients with juvenile nasopharyngeal angiofibroma (JNA), we developed a novel surgical strategy system. This system is focused on feeding artery management, based on the spatial relationship between the tumor entity and feeding artery as determined by three‐dimensional reconstruction.

The Effect of Voxel Volume and Voxel Shape on Cardiac Diffusion Tensor Imaging Metrics. [PDF]

Magn Reson Med
ABSTRACT Purpose Cardiac diffusion tensor imaging (cDTI) is signal‐to‐noise ratio (SNR)‐limited due to diffusion signal attenuation, long echo times from gradient moment nulling, and moderate myocardial T 2$$ {}_2 $$. Increasing voxel volume improves SNR but reduces spatial sensitivity and introduces physiological bias.

The Multilevel Implications of a Sinn Féin Government in Ireland

The Political Quarterly, Volume 96, Issue 1, Page 173-179, January/March 2025.
Abstract The electoral growth of Sinn Féin on both sides of the Irish border has generated much political and academic attention in recent years. The party could form part of the government in Dublin for the first time at the next Irish general election, though that outcome is far from certain.

South Africa: The Ambiguities of a Middle Power

Global Policy, EarlyView.
ABSTRACT South Africa represents an interesting species of a middle power. This derives from its inherited economic muscle as Africa's powerhouse and the liberation struggle against apartheid, both of which have shaped its democratic transition. The traditions of liberation and democracy, in turn, have profoundly influenced how South Africa has ...
