Policies that increase household income, such as the earned income tax credit (EITC), have shown reductions on risk factors for child maltreatment (ie, poverty, maternal stress, depression), but evidence is lacking whether EITC actually reduces maltreatment. We examined states' EITCs are associated with state rates of hospital admissions abusive head trauma among children aged <2 years.We conducted difference-in-difference analyses pre- and postdifferences in intervention vs control groups)...
Taking the concept of thin clients to limit, this paper proposes that desktop machines should just be simple, stateless I/O devices (display, keyboard, mouse, etc.) access a shared pool computational resources over dedicated interconnection fabric --- much in same way as building's telephone services are accessed by collection handset devices. The design provides useful mobility model which users can transparently resume their work on any console.This examines fundamental premise system...
We used screening techniques based on polymerase chain reaction (PCR) to explore the avian hematozoan parasites (Plasmodium spp. and Haemoproteus spp.) of two previously uninvestigated regions continental South America. Comparisons tropicalzone Guyana temperate-zone Uruguay revealed that overall prevalence Plasmodium species detected in a diverse sampling potential hosts was significantly higher Guyana. The difference between geographic zones appears be attributable ecological differences...
Interactive audio spatialization technology previously developed for video game authoring and rendering has evolved into an essential component of platforms enabling shared immersive virtual experiences future co-presence, remote collaboration entertainment applications. New wearable augmented reality displays employ real-time binaural computing engines multiple digital objects supporting the free navigation networked participants or their avatars through a juxtaposition environments, real...
The Division of Birds, National Museum Natural History, Smithsonian Institution in Washington, DC, has obtained and released DNA barcodes for 2,808 frozen tissue samples. Of the 1,403 species represented by these samples, 1,147 have not been barcoded previously. This data release increases number bird with standard 91%. These records meet Consortium Barcode Life they reserved keyword BARCODE GenBank. are now available on GenBank Data Systems.
Current knowledge about seasonal variation in the gut microbiota of vertebrates is limited to a few studies based on mammalian fecal samples. Seasonal changes microbiotas functionally distinct regions remain unexplored. We investigated (summer versus winter) and regionalization crop, ventriculus, duodenum, cecum, colon greater sage-grouse (Centrocercus urophasianus), an avian folivore specialized toxic foliage sagebrush (Artemesia spp.) western North America. sequenced V4 region 16S rRNA...
Abstract In concurrent computing environments based on heterogeneous processing elements interconnected by general‐purpose networks, several classes of overheads contribute to lowered performance. The most obvious limitations are network throughput and latency, but certain other factors also play a significant role. an attempt gain some insight into the nature these overheads, propose strategies alleviate them, empirical measurements native communication performance as well application...
A formula for the probability that a randomly generated n-polytope defined by m half-spaces is bounded presented. Results of simulation giving (i) all constraints are relevant and (ii) expected number vertices polytope,
A new genus of quill mites (Cheyletoidea: Syringophilidae) and two species Pipicobia terpsiphoni gen. nov. sp. Syringophiloidus furthi parasitizing the black-headed paradise-flycatcher Terpsiphone rufiventer (Swainson) (Passeriformes: Monarchidae) in Gabon are described. Three Neopicobia Skoracki, 2011 moved to newly established genus: locustella (Skoracki, Bochkov Wauthy, 2004) comb. nov., pyrrholaemus (Skoracki Glowska, 2008) comb.nov., glossopsitta Glowska Sikora, comb.nov. Syringophilids...
We describe a new species of forest robin from the Gamba Complex in southwest Gabon. This common bird, Stiphrornis pyrrholaemus sp. nov., inhabits primary lowland and forages on or near ground like other members genus central western Africa. Unique phenotypic features include male’s bright orange chin, throat, breast, creamy yellow belly, olive green back rump, gray flanks. Mitochondrial sequence divergence corroborates our assessment based its distinct physical characteristics that this is...
Stereotyped sunning behaviour in birds has been hypothesized to inhibit keratin-degrading bacteria but there is little evidence that solar irradiation affects community assembly and abundance of plumage microbiota. The monophyletic New World vultures (Cathartiformes) are renowned for scavenging vertebrate carrion, spread-wing at roosts, thermal soaring. Few avian species experience greater exposure irradiation. We used 16S rRNA sequencing investigate the microbiota wild individuals five...

A new genus and three species of the picobiin quill mites (Cheyletoidea: Syringophilidae) are described from passeriform birds in Guyana, Phipicobia pygiptilae gen. nov. sp. parasitizing Pygiptila stellaris (Spix) (Thamnophilidae), Rafapicobia thamnophili Thamnophilus insignis Salvin et Godman (type host), Myrmoborus leucophrys (Tschudi), Myrmeciza ferruginea (St. Müller), Myrmotherula longipennis Pelzeln, Hypocnemis cantator (Boddaert) milenskyi Conopophaga aurita (Gmelin) (Conopophagidae).
