Learning and comparing functional connectomes across subjects

Functional connectomes capture brain interactions via synchronized fluctuations in the functional magnetic resonance imaging signal. If measured during rest, they map the intrinsic functional architecture of the brain. With task-driven experiments they represent integration mechanisms between specialized brain areas. Analyzing their variability across subjects and conditions can reveal markers of brain pathologies and mechanisms underlying cognition. Methods of estimating functional connectomes from the imaging signal have undergone rapid developments and the literature is full of diverse strategies for comparing them. This review aims to clarify links across functional-connectivity methods as well as to expose different steps to perform a group study of functional connectomes

Low gravity liquid level sensor rake

The low gravity liquid level sensor rake measures the liquid surface height of propellant in a propellant tank used in launch and spacecraft vehicles. The device reduces the tendency of the liquid propellant to adhere to the sensor elements after the bulk liquid level has dropped below a given sensor element thereby reducing the probability of a false liquid level measurement. The liquid level sensor rake has a mast attached internal to a propellant tank with an end attached adjacent the tank outlet. Multiple sensor elements that have an arm and a sensor attached at a free end thereof are attached to the mast at locations selected for sensing the presence or absence of the liquid. The sensor elements when attached to the mast have a generally horizontal arm and a generally vertical sensor

Feasibility, safety and efficacy of enhanced recovery after living donor nephrectomy: systematic review and meta-analysis of randomized controlled trials.

This meta-analysis aims to compare enhanced recovery after surgery (ERAS) vs. standard perioperative practice in the management of living kidney donors. Primary endpoints included mortality, complications, length of stay (LOS) and quality of life after living donor nephrectomy. Medline, Embase, Scopus, Cochrane and Web of Science databases were searched. In total, 3029 records were identified. We then screened 114 full texts. Finally, 11 studies were included in the systematic review corresponding to 813 living donors. Of these, four randomized controlled trials were included in the meta-analysis. ERAS resulted in shorter LOS (95CI: -1.144, -0.078, I2 = 87.622%) and lower incidence of post-operative complications (95CI: 0.158, 0.582, I2 = 0%). This referred to Clavien-Dindo I-II complications (95CI: 0.158, 0.582, I2 = 0%). There was no difference in Clavien-Dindo III-V complications (95CI: 0.061,16.173, I2 = 0%). ERAS donors consumed decreased amounts of narcotics during their hospital stay (95CI: -27.694, -8.605, I2 = 0%). They had less bodily pain (95CI:6.735, 17.07, I2 = 0%) and improved emotional status (95CI: 6.593,13.319, I2 = 75.682%) one month postoperatively. ERAS protocols incorporating multimodal pain control interventions resulted in a mean reduction of 1 day in donors' LOS (95CI: -1.374, -0.763, I2 = 0%). Our results suggest that ERAS protocols result in reduced perioperative morbidity, shorter length of hospital stay and improved quality of life after living donor nephrectomy

Apparatus and Method for Harvesting Carbon Nanotube Arrays

An apparatus is provided for harvesting a carbon nanotube array from a substrate. The apparatus includes a peeler that peels the carbon nanotube array from the substrate and a support that receives the carbon nanotube array peeled from the substrate. In addition the apparatus includes a drawing device that simultaneously draws the carbon nanotube array from the substrate onto the support as the carbon nanotube array is peeled from the substrate. The peeler and drawing device are synchronized in operation so that as a given length of carbon nanotube array is peeled from the substrate, that same given length of carbon nanotube array is drawn onto the support

Colourism: a global adolescent health concern

PURPOSE OF REVIEW: Colourism, a form of prejudice and discrimination based solely upon skin colour, stands to jeopardize the physical health, wellbeing and life chances of adolescents of colour, globally. RECENT FINDINGS: Research shows that adolescents can experience colourism at school and college, in the criminal justice system, at work and in the media they consume. It is therefore unsurprising that adolescents of colour often express a desire for lighter skin tones and/or are dissatisfied with their skin tone. Although research is scarce, some studies include older adolescents in their samples of skin-lightening product users. This is significant as the evidence is clear that the unmonitored use of skin-lightening products can be harmful to physical and psychological health, with evidence linking skin-lightening use to skin damage, kidney failure and depression. SUMMARY: Although it is evident that colourism is central to the lives of adolescents of colour, more research is needed concerning the use of skin-lightening products among adolescents. Media literacy and critical race theory offer avenues in helping attenuate the harmful impact of colourism for adolescents of colour
