Unmanned aerial vehicles (UAVs) in cellular networks have garnered considerable interest. One of their applications is as flying base stations (FBSs), which can increase coverage and quality service (QoS). Because FBSs are battery-powered, regulating energy usage a vital aspect use; therefore, the appropriate placement trajectories throughout operation critical to overcoming this challenge. In ...

A broken snapshot represents a snapshot from a project’s change history that cannot be compiled. Broken snapshots can have significant implications for researchers, as they could hinder any analysis of the past project history that requires code to be compiled. Noticeably, while some broken snapshots may be observable in change history repositories (e.g., no longer available dependencies), some...

Flow visualization techniques using tracer markers such as die, smoke, hydrogen bubbles, etc., have been widely used in experimental investigations of large scale structures of a variety of flow fields. They have played an important role in understanding the physics of the coherent structures formation and evolution in the transitional as well as the turbulent regions of the flow fields. Howeve...

Estrogen and progestin concentrations in plasma and follicular fluid (FF) of follicles within the small (5 to 100/A), medium (101 to 400 gd) and large (>400 gtl) range, numbers of follicles and volume of FF per follicle within these ranges were determined in beef heifers. There were differences (P<.01) in mean concentrations (+SE) of steroids among and within follicles from the small, medium an...

Multiparous beef cows (n = 7) were used to evaluate peripartum changes and interactions among body temperature (BT) and circulating progesterone (P4), estradiol-17beta (E2), triiodothyronine (T3), cortisol, thyroxine (T4), and 13,14-dihydro-15-keto-prostaglandin F2alpha (PGFM) concentrations. Electronic temperature monitors were placed under the obliquus abdominis internus muscle of the left fl...

An unidentified Helicobacter species, strain MIT 01-6451, was frequently detected in mice obtained from domestic commercial and academic institutions in Japan. To partially characterize this strain, its distributions in the gastrointestinal tract and hepatobiliary system of mice were investigated. In gastrointestinal tissues, this strain was detected in all cecum, colon, and feces samples teste...
