#1
A González-Tudela, J I Cirac
We show that the coupling of quantum emitters to a two-dimensional reservoir with a simple band structure gives rise to exotic quantum dynamics with no analogue in other scenarios and which cannot be captured by standard perturbative treatments. In particular, for a single quantum emitter with its transition frequency in the middle of the band, we predict an exponential relaxation at a rate different from that predicted by Fermi's golden rule, followed by overdamped oscillations and slow relaxation decay dynamics...

OBJECTIVES: To assess how integration of HIV surveillance and field services might influence surveillance data and linkage to care metrics. METHODS: We used HIV surveillance and field services data from King County, Washington, to assess potential impact of misclassification of prior diagnoses on numbers of new diagnoses. The relationship between partner services and linkage to care was evaluated with multivariable log-binomial regression models. RESULTS: Of the 2842 people who entered the King County HIV Surveillance System in 2010 to 2015, 52% were newly diagnosed, 41% had a confirmed prior diagnosis in another state, and 7% had an unconfirmed prior diagnosis...

The clinical diagnosis of malformations of cortical development (MCDs) is often challenging due to the complexity of the brain malformation by neuroimaging, the rarity of individual malformation syndromes, and the rapidly evolving genetic landscape of these disorders facilitated with the use of Next Generation Sequencing (NGS) methods. While the clinical and molecular diagnosis of severe cortical malformations, such as classic lissencephaly, is often straightforward, the diagnosis of more subtle and complex types of cortical malformations, such as pachygyria and polymicrogyria (PMG), can be more challenging due to limited knowledge regarding their genetic etiologies...

BACKGROUND: Genetic polymorphisms within the glutathione S-transferase P1 (GSTP1) gene affect the elimination of toxic xenobiotics by the GSTP1 enzyme. In dogs, exposure to environmental chemicals that may be GSTP1 substrates is associated with cancer. The objectives of this study were to investigate the genetic variability in the GSTP1 promoter in a diverse population of 278 purebred dogs, compare the incidence of any variants found between breeds, and predict their effects on gene expression...

Numerous centrality measures have been developed to quantify the importances of nodes in time-independent networks, and many of them can be expressed as the leading eigenvector of some matrix. With the increasing availability of network data that changes in time, it is important to extend such eigenvector-based centrality measures to time-dependent networks. In this paper, we introduce a principled generalization of network centrality measures that is valid for any eigenvector-based centrality. We consider a temporal network with N nodes as a sequence of T layers that describe the network during different time windows, and we couple centrality matrices for the layers into a supra-centrality matrix of size NT × NT whose dominant eigenvector gives the centrality of each node i at each time t...

Background: Antimicrobial-resistant Neisseria gonorrhea is a major public health threat. The CDC recommends that clinicians treat gonorrhea with ceftriaxone 250mg plus azithromycin 1g. Resistance to azithromycin could affect gonorrhea control efforts. Methods: We evaluated antimicrobial susceptibility profiles and clinical data of gonococcal isolates collected at the Public Health-Seattle & King County (PHSKC) STD Clinic from 2012-2016, focusing on 2014-2016. We compared cases with CDC azithromycin (AZM) alert value MIC (MIC ≥2 µg/mL) to those with AZM MIC ≤1 µg/mL, and evaluated clinical outcomes...

Sustainable food systems are an important component of a planetary health strategy to reduce the threat of infectious disease, minimize environmental footprint and promote nutrition. Human population trends and dietary transition have led to growing demand for food and increasing production and consumption of meat, amid declining availability of arable land and water. The intensification of livestock production has serious environmental and infectious disease impacts. Land clearing for agriculture alters ecosystems, increases human-wildlife interactions and leads to disease proliferation...

Large Hesperian-aged (~3.7 Ga) layered deposits of sulfate-rich sediments in the equatorial regions of Mars have been suggested to be evidence for ephemeral playa environments. But early Mars may not have been warm enough to support conditions similar to what occurs in arid environments on Earth. Instead cold, icy environments may have been widespread. Under cryogenic conditions sulfate formation might be blocked, since kinetics of silicate weathering are typically strongly retarded at temperatures well below 0 °C...

Natural selection in domestic dogs is of great interest in evolutionary biology since dogs have migrated to every inhabited continent of the world alongside humans, and adapted to diverse environments. Here, we explored their demographic history and genetic basis of adaptation to the tropical African environment using whole genome analyses of 19 African indigenous dogs from Nigeria. Demographic analysis suggests that the ancestors of these dogs migrated into Africa from Eurasia 14,000 years ago and underwent a severe founder effect before population expansion...

STUDY QUESTION: What is the role of metachronal and synchronous sliding in sperm flagellar motility? SUMMARY ANSWER: Both metachronal and oscillatory synchronous sliding are essential for sperm flagellar motility, while the change in mode of synchronous sliding between the non-oscillatory synchronous sliding of a specific pair of the doublet microtubules and the oscillatory synchronous sliding between most pairs of doublet microtubules modulates the sperm flagellar motility...

BACKGROUND: Most combat casualties who die, do so in the prehospital setting. Efforts directed toward alleviating prehospital combat trauma death, known as killed in action (KIA) mortality, have the greatest opportunity for eliminating preventable death. METHODS: 4,542 military casualties injured in Afghanistan from September 11, 2001 to March 31, 2014 were included in this retrospective analysis to evaluate proposed explanations for observed KIA reduction following a mandate by Secretary of Defense Robert M...

Angiostrongylosis caused by metastrongyloid nematode Angiostrongylus vasorum is an emerging parasitic disease in Europe and the red fox (Vulpes vulpes) is considered as a main reservoir species for this parasite. Little is known about the role of other wild canids in the epidemiology of angiostrongylosis. The present paper provides the first description of pathomorphological lesions caused by A. vasorum in a golden jackal (Canis aureus). The paper describes a case of co-infection with A. vasorum and Dirofilaria immitis in a one-year-old female golden jackal, legally hunted near the City of Kovin, South Banat, Serbia...

Bacteria and archaea rely on CRISPR (clustered regularly interspaced short palindromic repeats) RNA-guided adaptive immune systems for sequence specific elimination of foreign nucleic acids. In Escherichia coli, short CRISPR-derived RNAs (crRNAs) assemble with Cas (CRISPR-associated) proteins into a 405-kilodalton multi-subunit surveillance complex called Cascade (CRISPR-associated complex for antiviral defense). Cascade binds foreign DNA complementary to the crRNA guide and recruits Cas3, a trans-acting nuclease-helicase required for target degradation...

Increasing the per-unit cost of tobacco products is one of the strongest interventions for tobacco control. In jurisdictions with higher taxes in the U.S., however, cigarette pack litter studies show a substantial proportion of littered packs lack the appropriate tax stamp. More limited but still present counterfeiting also exists. We sought to examine the role of tobacco retailers as a source for untaxed and counterfeit products. Data collectors purchased Newport Green (menthol) or Marlboro Red cigarette packs in a national probability-based sample of tobacco retailers (in 97 counties) from June-October 2012...

The past decades have been a golden era when great tasks were accomplished in the field of microbiology including food microbiology. In the past, culture dependent methods have been the primary choice to investigate the bacterial diversity. However, using culture independent high throughput sequencing of 16S rRNA genes has greatly facilitated studies exploring the microbial compositions and dynamics associated with health and diseases. These culture independent DNA based studies generate large-scale data sets that describe the microbial composition of the certain niche...

Although the term "personalized medicine" has been associated in many cases with pharmacogenomics, its definition embraces the use of specific biomarkers and covariates to help in the selection of medical treatments and procedures which are best for each patient. While several efforts have been performed for the tailored selection of therapies and dosing regimens in the general population, developing personalized medicine initiatives for elderly patients remains understudied. The personalized drug therapy for older patients requires the consideration of anatomical, physiological and functional alterations in a multimorbid setting requiring multiple medications...

Executive dysfunction occurs early and is prevalent in Alzheimer's disease (AD). This study tested the ability of different measures for identifying changes in executive function and the effect of 6-months of aerobic exercise on executive function in older adults with mild to moderate AD, using a single-group, repeated-measures design (n = 28, age 78.1 ± 8.37). Factor analysis and linear mixed-effects model analyses showed that individually the Exit Interview-25 (EXIT-25), Behavioral Dyscontrol Scale (BDS), and Golden Stroop test were the preferred instruments for measuring changes in executive function in the sample...
