In most e-commerce platforms, product title classification is a crucial task. It can assist sellers listing an item in an appropriate category. At first glance, product title classification is merely an instance of text classification problems, which are well-studied in literature. However, product titles possess some properties very different from general documents. A title is usually a very s...

Noninterference provides a control over information flow in a system for ensuring confidentiality and integrity properties. In the literature this notion has been well studied as transitive noninterference and intransitive noninterference. In this paper we define a framework on the notion of conditional noninterference, which allows to specify information flow policies based on the semantics of...

Suppose that N players share cryptocurrency using an M out-of-N multisig scheme. If N−M+1 players disappear, the remaining ones have a problem: They’ve permanently lost their funds. We introduce Paralysis Proofs. A Paralysis Proof is a proof that players cannot act in concert, e.g., some players have become unavailable. Paralysis Proofs can support the construction of a Paralysis Proof System, ...

While classical location problems deal with finding optimal locations for facilities, the task of the corresponding upgrading (downgrading) version is to change the underlying network within certain bounds such that the optimal objective value that can be obtained in the modified network is as good (bad) as possible. In this paper we allow to change the vertex weights within given bounds such t...

Feature design and selection is a crucial aspect when treating terminology extraction as a machine learning classification problem. We designed feature classes which characterize different properties of terms, and propose a new feature class for components of term candidates. By using random forests, we infer optimal features which are later used to build decision tree classifiers. We evaluate ...

Following a period in the 1990s of rapid integration into the production and trade networks of the European Union (and to a lesser extent of the United States), clothing manufacturers in East and Central Europe have had to quickly adjust to the changing costs of production with EU accession, the rise of Chinese exports, and the January 1, 2005 final phase-out of quantitative quotas into major m...

This paper assesses the industrial performance and capabilities of Nigeria over the last decade. It explores Nigeria’s export and production capacity, growth, structure and technological upgrading and compares it to other Sub-Saharan countries. Evidence shows that Nigerian industry is inexorably falling behind and becoming increasingly marginalized in the international and regional industrial s...

This paper introduces an alternative approach to the camber angle measurement for vehicle wheel alignment. Instead of current commercial approaches that apply computation vision techniques, this study aims at realizing a micro-control-unit (MCU)-based camber inspection system with a 3-axis accelerometer. We analyze the precision of the inspection system for the axis misalignments of the acceler...

Preoperative Gleason score (GS) obtained from Trans Rectal Ultra Sonography (TRUS) is the most common grading system to evaluate the appropriate treatment for patients with clinically localized prostate cancer. But this method showed upgraded and downgraded results in comparison to Gleason score obtained from radical prostatectomy. The current study aimed to determine clinical or pathological v...

In this article, we report findings from the first qualitatively driven study of patient-clinician communication in Hong Kong Accident and Emergency Departments (AEDs). In light of the Hong Kong Hospital Authority's policy emphasis on patient-centered care and communication in the public hospitals it oversees, we analyze clinicians' perceptions of the role and relevance of patient-centered comm...
