A CMOS single-photon avalanche diode (SPAD) quanta image sensor is used to reconstruct depth and intensity profiles when operating in a range-gated mode used in conjunction with pulsed laser illumination. By designing the CMOS SPAD array to acquire photons within a pre-determined temporal gate, the need for timing circuitry was avoided and it was therefore possible to have an enhanced fill factor (61% in this case) and a frame rate (100,000 frames per second) that is more difficult to achieve in a SPAD array which uses time-correlated single-photon counting...

Racial discrimination has been increasingly reported to have a causal link with morbidity and mortality of Black Americans, yet this issue is rarely addressed in a public health perspective. Racism affects health at different levels: institutional racism is a structural and legalized system that results in differential access to health services; cultural racism refers to the negative racial stereotypes, often reinforced by media, that results in poorer psychological and physiological wellbeing of the minorities...

In declining birches (Betula sp.) from different European stands affected by the "birch leaf-roll disease" (BLRD) a novel virus is identified by means of RNA-Seq virome analysis. The virus represents a new member in the genus Badnavirus, family Caulimoviridae, tentatively named Birch leaf roll-associated virus (BLRaV) and it is the first badnavirus found to infect birch. Complete genome sequences (7,862-7,864 nucleotides) of three viral isolates of Finnish and German origin have been determined. The virus sequences show a typical badnavirus organization with three major open reading frames (ORFs) and a fourth potential ORF overlapping with the end of ORF3...

Translation initiation in eukaryotes is a highly regulated and rate-limiting process. It results in the assembly and disassembly of numerous transient and intermediate complexes involving over a dozen eukaryotic initiation factors (eIFs). This process culminates in the accommodation of a start codon marking the beginning of an open reading frame at the appropriate ribosomal site. Although this process has been extensively studied by hundreds of groups for nearly half a century, it has been only recently, especially during the last decade, that we have gained deeper insight into the mechanics of the eukaryotic translation initiation process...

BACKGROUND: Despite international recommendations and supportive evidence, there are few examples of scaled-up and sustained programs to provide adolescents with sexuality education. Moreover, despite acknowledgment that building community support and responding to resistance are key challenges, there is a lack of detailed discussion on specific programmatic strategies to address these issues. OBJECTIVES: This article reviews the work of 2 organizations-Aahung and Rutgers Pakistan-that are successfully implementing large-scale sexuality education programs in Pakistan, collectively reaching more than 500,000 students...

Sea urchins have a globiferous pedicellaria that stands from a test with a stalk on which lies a head made of three movable jaws with venom-injecting teeth. The globiferous pedicellariae of the flower sea urchin Toxopneustes pileolus, one of the most developed among sea urchins, are unique in that the jaws are provided with a jaw membrane that gives the pedicellaria an appearance of a flower when the jaws are open. We observed this membrane in an ionic liquid that does not require processes, such as fixation, dehydration, or coating with conductive materials, for observation with a scanning electron microscope...

INTRODUCTION: Severe lower-limb trauma is a major event in a patient's life, and treatment is a challenge that has not been sufficiently studied. The main objective of the present study was to assess the difference in disability between amputees and patients who kept their leg after severe open lower-limb fracture. HYPOTHESIS: The study hypothesis was that amputation allows better functional recovery and quality of life, in the same time-frame. MATERIALS AND METHODS: All male and female patients aged over 18 years admitted to one of the trauma centers of Marseille (France) for major lower-limb trauma with Gustilo IIIb or IIIc fracture were included...

Prior studies have demonstrated that correlated variability changes with cognitive processes that improve perceptual performance. We tested whether correlated variability covaries with subjects' performance-whether performance improves quickly with attention or slowly with perceptual learning. We found a single, consistent relationship between correlated variability and behavioral performance, regardless of the time frame of correlated variability change. This correlated variability was oriented along the dimensions in population space used by the animal on a trial-by-trial basis to make decisions...

Crop models are used for an increasingly broad range of applications, with a commensurate proliferation of methods. Careful framing of research questions and development of targeted and appropriate methods are therefore increasingly important. In conjunction with the other authors in this special issue, we have developed a set of criteria for use of crop models in assessments of impacts, adaptation and risk. Our analysis drew on the other papers in this special issue, and on our experience in the UK Climate Change Risk Assessment 2017 and the MACSUR, AgMIP and ISIMIP projects...

Background: An informal care-giver is generally an unpaid individual who looks after the personal and medical needs of the patient. India being a country of traditions and family values, this informal care-giver is usually a family member. These care-givers, being untrained in this job undergo tremendous stress. Available research studies the burden individually in the relatives of chronically medically ill patients and those of psychiatrically ill patients. Furthermore the previous research targets the burden in individual diseases...

Subsocial wood feeding cockroaches in the genus Cryptocercus, the sister group of termites, retain their symbiotic gut flagellates during the host molting cycle, but in lower termites, closely related flagellates die prior to host ecdysis. Although the prevalent view is that termite flagellates die because of conditions of starvation and desiccation in the gut during the host molting cycle, the work of L.R. Cleveland in the 1930s through the 1960s provides a strong alternate hypothesis: it was the changed hormonal environment associated with the origin of eusociality and its concomitant shift in termite developmental ontogeny that instigates the death of the flagellates in termites...

DNA molecular machines show great promise in fields such as biomarker discovery and biological activity regulation, but operating DNA machines with specific functions within living systems remains extremely challenging. Although DNA machines have been engineered with exact molecular-level specifications, some intrinsic imperfections such as poor cell permeation and fragility in complex cytoplasmic milieu persist due to the well-established character of nucleic acid molecules. To circumvent these problems, we herein report a molecularly engineered, entropy-driven three-dimensional DNA amplifier (EDTD) that can operate inside living cells in response to a specific mRNA target...

BACKGROUND AND IMPORTANCE: The authors report a novel external scalp retraction technique for sunken skin flap syndrome (SSFS). CLINICAL PRESENTATION: A 48-year-old male patient suffered neurological deterioration due to SSFS after decompressive craniectomy. Cranioplasty is the gold standard for therapeutic management of SSFS, but could not be performed due to intracranial wound infection. The patient underwent external fixation of a metal plate as a frame for the skull and the scalp was pulled outward to the frame by skin suture...

Current commercial wearable gait exoskeletons contain joints with stiff actuators that cannot adapt to unpredictable environments. These actuators consume a significant amount of energy, and their stiffness may not be appropriate for safe human-machine interactions. Adjustable compliant actuators are being designed and implemented because of their ability to minimize large forces due to shocks, to safely interact with the user, and to store and release energy in passive elastic elements. Introduction of such compliant actuation in gait exoskeletons, however, has been limited by the larger power-to-weight and volume ratio requirement...

BACKGROUND: Consensus opinion supports standing frame use as part of postural management for nonambulant young people with cerebral palsy. Although the rationale for standing frame use and the associated challenges have been described, little attention has been given to the users' experiences. The aim of the current study was to explore young people's positive and negative experiences, and attitudes regarding standing frame use. METHODS: Framework analysis informed an open exploration of young people's opinions of standing frames...

The group 1 pathogenesis-related (PR-1) proteins originally identified from plants and their homologues are also found in other eukaryotic kingdoms. Studies on non-plant PR-1-like (PR-1L) proteins have been pursued widely in humans/animals but rarely in filamentous ascomycetes. Here we report the characterization of four PR-1L proteins identified from the ascomycete fungus Fusarium graminearum, the primary cause of Fusarium head blight of wheat and barley. Molecular cloning revealed that the four FgPR-1L proteins are all encoded by small open reading frames (612 to 909 bp) that are often interrupted by introns, in contrast to plant PR-1 genes that lack introns...

Organic electrodes are potential alternatives to current inorganic electrode materials for lithium ion and sodium ion batteries powering portable and wearable electronics, in terms of their mechanical flexibility, function tunability and low cost. However, the low capacity, poor rate performance and rapid capacity degradation impede their practical application. Here, we concentrate on the molecular design for improved conductivity and capacity, and favorable bulk ion transport. Through an in situ cross-coupling reaction of triethynylbenzene on copper foil, the carbon-rich frame hydrogen substituted graphdiyne film is fabricated...
