InfiniBand System Area Networks using link-level flow control can experience congestion spreading, where one bottleneck link causes traffic to block throughout the network. End-to-end congestion control using Explicit Congestion Notification (ECN) packet marking has the potential to solve this problem. In this paper, we develop and evaluate ECN mechanisms for switches with input-buffered config...

transcatheter aortic valve replacement (tavr) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. since the initial partner trial results, use of tavr has been on the rise each year. new delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...

BACKGROUND Recently, endoscopic interventions (eg, esophageal stenting) have been successfully used for the management of intrathoracic leak. The purpose of this systematic review was to assess the safety and efficacy of techniques used in the management of intrathoracic anastomotic leak. DATA SOURCES We performed a systematic review of MEDLINE, EMBASE, and PubMed to identify eligible studies...

All manned spacecraft are vulnerable to leaks generated by micrometeorite or debris impacts. Methods for locating such leaks using leak-generated, structure-borne ultrasonic noise are discussed and demonstrated. Cross-correlations of ultrasonic noise waveforms from a leak into vacuum are used to find the location of the leak. Four methods for sensing and processing leak noise have been develope...

BACKGROUND Surgical site marking is one important cornerstone for the principles of safe surgery suggested by the WHO. Generally it is recommended that the attending surgeon performs the surgical site marking. Particularly in the case of same day surgery, this recommendation is almost not feasible. Therefore we systematically monitored, whether surgical site marking can be performed by trained ...

OBJECTIVE To determine pre-/intraoperative risk factors for anastomotic leak after colon resection for cancer and to create a practical instrument for predicting anastomotic leak risk. BACKGROUND Anastomotic leak is still the most dreaded complication in colorectal surgery. Many risk factors have been identified to date, but multicentric prospective studies on anastomotic leak after colon res...

This paper calls for a reexamination of the Marking Theory of HPSG, which in its standard form involves a considerable amount of dedicated formal machinery, but which proves to be inapplicable for most types of grammatical marking. As an alternative, it is demonstrated that head-marker phrases can be reanalyzed as head-complement structures, with the marking element treated as the syntactic hea...

Adolescence is a period during which many social behaviors emerge. One such behavior, flank marking, is a testosterone-modulated scent marking behavior that communicates dominance status between adult male Syrian hamsters. Testosterone modulates flank-marking behavior by altering neural transmission of vasopressin within a forebrain circuit. This study tested whether testicular hormones secrete...

We present Wave menus, a variant of multi-stroke marking menus designed for improving the novice mode of marking while preserving their efficiency in the expert mode of marking. Focusing on the novice mode, a criteria-based analysis of existing marking menus motivates the design of Wave menus. Moreover a user experiment is presented that compares four hierarchical marking menus in novice mode. ...
