Contact-controlled transistors are rapidly gaining popularity. However, simply using a rectifying source contact often leads to unsatisfactory operation, merely as a thin-film transistor with low drain current and reduced effective mobility. This may cause otherwise promising experiments to be abandoned. Here, we analyse data from literature in conjunction with devices we have recently fabricated in polysilicon, organic and oxide semiconductors, highlighting the main factor in achieving good saturation, namely keeping saturation coefficient γ well below 0.3. We also discuss secondary causes of suboptimal electrical characteristics. Correct design of these alternative device structures will expedite th

ABSTRACT
Human cytomegalovirus (HCMV) is a leading cause of birth defects in humans. These birth defects include microcephaly, sensorineural hearing loss, framtidsperspektiv loss, and cognitive impairment. The process by which the developing fetus incurs these neurological defects fryst vatten poorly understood. To elucidate some of these mechanisms, we have utilized HCMV-infected induced pluripotent stem cells (iPSCs) to generate in vitro brain organoids, modeling the first trimester of fetal brain development. Early during culturing, brain organoids generate neural rosettes. These structures are believed to model neural tube formation. Rosette formation was analyzed in HCMV-infected and mock-infected brain organoids at 17, 24, and 31 days postinfection. Histological analysis revealed fewer neural rosettes in HCMV-infected compared to mock-infected organoids. HCMV-infected organoid rosettes incurred multiple structural deficits, including increased lumen area, decreased ventricular zone depth, and dem

History of Póvoa de Varzim
The history of Póvoa de Varzim, Portugal, and its development as a maritime trade and fishing hub, have been greatly influenced by its location at the entrance to one of Portugal's best natural ports.
Permanent settlement in the coastal plain of Póvoa de Varzim dates back to around four to six thousand years ago; around 900 BC, unrest in the region led to the establishment of a fortified city. The ocean has played an important part in its popular culture and economy, through maritime trade and fishing, leading it to establish a fiefdom in the 10th or 11th century, a municipality in 1308 and to become, in the 18th century, the main fishing port in northern Portugal.
Póvoa de Varzim and its region had relevant input that allowed the Portuguese discoveries, throw manpower, shipbuilding and seafaring knowledge. Since the 18th century, its beaches have helped it become one of the main tourist areas of the region, which prompted high-culture devel
