Tracheal ultrasonography was performed to measure the width of the tracheal ring shadow and to assess the clinical relevance of these measurements for identifying tracheal collapse. The first tracheal ring width (FTRW) and thoracic inlet tracheal ring width (TITRW) were measured on both expiration and inspiration. The mean of the FTRW width (129 dogs) was greater in expiration (10.97 plusmn; 1....

When consumers search for and check expiration dates, the risk of purchasing a stale and diminishing quality product reduces. The authors use a simulated eye tracking enabled IT mediated environment to understand the underlying motivation of consumers for checking expiration dates while purchasing groceries. Preliminary findings suggest that expiration date plays an important role in consumers'...

When total parking supply in an urban downtown area is insufficient, morning commuters would choose their departure times not only to trade off bottleneck congestion and schedule delays, but also to secure a parking space. Recent studies found that an appropriate combination of reserved and unreserved parking spaces can spread the departures of those morning commuters and hence reduce their tot...

[Purpose] The purpose of this investigation was to compare the activities of the abdominal muscles and peak expiratory flow between forced vital capacity and fast expiration exercise. [Subjects and Methods] Fifteen healthy male participated in this study. Peak expiratory flow and electromyographic activities of the rectus abdominis, external oblique, and internal oblique/transversus abdominis m...

Caching data together with expiration times beyond which the data are no longer valid is a standard method for promoting information coherence in distributed systems, including the Internet, the World Wide Web (WWW), and Peer-to-Peer (P2P) networks. We use the framework of competitive analysis of online algorithms and study upper and lower bounds for page eviction strategies in the case where d...

BACKGROUND Because a recent cluster of false positive results on the OraQuick ADVANCE Rapid HIV-1/2 Antibody Test occurred in San Francisco on test kits close to their expiration date, we decided to assess the relationship between time to expiration and rate of false positive results from tests used with oral fluid. METHODOLOGY/PRINCIPAL FINDINGS We analyzed results of 20,904 tests with eithe...

This paper explores price effects caused by the expiration of derivatives in cryptocurrency market. Applying different statistical tests (ANOVA, Mann–Whitney, and t-tests) econometric methods (the modified cumulative abnormal return approach, regression analysis with dummy variables, trading simulation approach) to daily weekly Bitcoin data over period 2018–2021, following hypotheses are tested...
