While most ecological studies have shown that higher levels of point-of-sale (POS) cigarette marketing are associated with larger proportions of residents from lower socioeconomic and minority backgrounds in neighborhoods, there are no studies that examine individual-level social disparities in exposure to POS cigarette marketing among smokers in the United States. Our aim was to examine these ...

Ein typisches Beispiel für dieses Problem sind Kassensysteme (POS-Systeme). An diese werden folgende Anforderungen gestellt: Aus Softwareherstellersicht spielt Wiederverwendung und Wartbarkeit eine große Rolle. Aus Kundensicht sind in der Regel eine Reihe individueller Lösungen zu realisieren: Implementierung kundenspezifischer Workflows, variable Anpassung an verschiedene Umgebungen, z.B. wenn...

We implement a variant of the algorithm described by Yarowsky and Ngai in [21] to induce an HMM POS tagger for an arbitrary target language using only an existing POS tagger for a source language and an unannotated parallel corpus between the source and target languages. We extend this work by projecting from multiple source languages onto a single target language. We hypothesize that systemati...

Bitcoin and its underlying blockchain mechanism have been attracting much attention. One of their core innovations, Proof-of-Work (PoW), is notoriously inefficient which potentially motivates a centralization of computing power, defeating the original goal of decentralization. Proof-of-Stake (PoS) is later proposed to replace PoW. However, both PoW and PoS have different inherent advantages and...

This study explores whether exposure to advertisements that focus on the negative effects of tobacco industry advertising and promotion at the point of sale (anti-POS advertising) influence: (i) attitude toward POS advertising; (ii) perceived impact of POS advertising on youth smoking; and (iii) support for a ban on tobacco promotion at the POS among adult non-smokers in New York. Data are from...

Recent work on joint word segmentation, POS (Part Of Speech) tagging, and dependency parsing in Chinese has two key problems: the first is that word segmentation based on character and dependency parsing based on word were not combined well in the transition-based framework, and the second is that the joint model suffers from the insufficiency of annotated corpus. In order to resolve the first ...

A finite group G is said to be a POS-group if for each x in G the cardinality of the set {y in G | o(y) = o(x)} is a divisor of the order of G. In this paper we study the structure of POS-groups with some cyclic Sylow subgroups.
