Abstract Aiming at the problems of high-altitude painting, an intelligent painting unmanned aerial vehicle (UAV) system, including hardware design and software implementation, has been developed. The system mainly includes three parts: drawer-type modular power supply, UAV control high airflow ultra-high-speed motor drive system. realization two thread high-voltage main solenoid valve for openi...

And a stylish duckegg plate I brought From one of my adventures— Free and full of guff and gravitas And mortgaged to the hilt Of her gritted, contending heart— The plate for hanging up She trussed with a ragged strip Of worn out sheet before consignment To a drawer bottomed with curtain hooks, medals, florins, a calendar page In a cursive, rushing hand, noting the birthdates Breed and sex of fo...

How do you choose your HPLC columns? I guess the answer to this varies widely and I’ve seen many strategies being employed including; whatever is on the instrument, first one out of the column drawer, the one that was successful for my last development, from a publication or application, my favourite column from my favourite supplier, we have a set of orthogonal chemistries on our automated col...

OBJECTIVE The objective of this study was to evaluate the results obtained from posterior cruciate ligament (PCL) reconstruction with the double femoral tunnel technique, using quadriceps tendon and semitendinous autograft, in patients with isolated PCL tears or PCL tears associated with other ligament lesions, 2 years after surgery. METHODS The study included 14 patients with isolated PCL le...

BACKGROUND AND AIM Inadequately designed equipment has been implicated in poor efficiency and critical incidents associated with resuscitation. A novel resuscitation trolley (Resus:Station) was designed and evaluated for impact on team efficiency, user opinion, and teamwork, compared with the standard trolley, in simulated cardiac arrest scenarios. METHODS Fifteen experienced cardiac arrest t...

Because scientists tend to report only studies (publication bias) or analyses (p-hacking) that "work," readers must ask, "Are these effects true, or do they merely reflect selective reporting?" We introduce p-curve as a way to answer this question. P-curve is the distribution of statistically significant p values for a set of studies (ps < .05). Because only true effects are expected to generat...

470 sleep EEGs from 366 healthy participants in a light-controlled sleep laboratory (see Experimental Procedures in Supplemental Information, published with this article online). Lunar classes were defined as previously [2], with lunar class 1 representing full moon ± 4 nights, lunar class 2 covering the waxing and waning moon periods (full moon ± 5–9 nights) and lunar class 3 representing new ...

This paper reports an investigation of the turn-taking functions of drawings in graphical communication. Based on the examination of dialogue data collected that involve collaborative drawing interactions, as well as spoken dialogue interactions, in a joint problem solving task, we found that ‘drawing turns,’ in which the drawer presents a piece of information to her partner through drawing, ha...

Introduction: The anterior cruciate ligament (ACL) is an important restraint to anterior posterior translation and torsional stability of the knee joint[1]. After ACL rupture the role of the secondary restraints become of primary importance in ensuring knee joint stability[2][3][4]. The aim of this study was to investigate the effect of chronic ACL deficiency on the secondary restraints by meas...
