Character of holes in LixNi1-xO and their magnetic behavior.

Using oxygen $K$-edge x-ray-absorption spectroscopy we show that the holes compensating the ${\mathrm{Li}}^{1+}$ impurity charge in ${\mathrm{Li}}_{x}{\mathrm{Ni}}_{1\ensuremath{-}x}\mathrm{O}$ are located primarily in the O $2p$ states rather than in the conventionally assumed Ni $3d$ states. These holes are bound to the ${\mathrm{Li}}^{1+}$ impurities forming states in the NiO band gap. We also argue that these O $2p$ holes have a very large antiferromagnetic exchange interaction with neighboring ${\mathrm{Ni}}^{2+}$ (${d}^{8}$) spins, which makes them appear like low-spin ${\mathrm{Ni}}^{3+}$ states in macroscopic magnetic measurements. This is similar to what could be happening in the Cu-based high-${T}_{c}$ superconductors.
Dinosaurios de Aragón

Los dinosaurios de Aragon representan uno de los registros mas amplios de estos fosiles en Espana. Los restos mas antiguos provienen del Tithonico de Galve (Teruel) y los mas modernos del Maastrichtiense superior de Aren (Huesca). Se han encontrado en las tres provincias aragonesas, siendo en Teruel donde hay mayor numero de yacimientos del Jurasico Superior - Cretacico Inferior y en Huesca del Cretacico Superior. Los sauropodos de Aragon son del Cretacico Inferior y se puede destacar que son dos de los dinosaurios mas completos de Espana. El genero Aragosaurus del Hauteriviense de Galve (Teruel) y el dinosaurio del Aptiense de Penarroya de Tastavins (Teruel) que esta pendiente de describir. Los dientes aislados y las huellas son los restos mas abundantes de los terodopos, apareciendo dientes en todos los yacimientos que se ha lavado sedimentos. Los teropodos aunque escasos, estan presentes en todo el registro, sus restos, generalmente de pequeno tamano solo se pueden recuperar mediante tecnicas de lavado-tamizado y disolucion por acidos. Los restos de ornitopodos son los fosiles mas abundantes en el Cretacico, los iguanodontidos e hypsilofodonditos en el Inferior y los hadrosauridos en el Superior. Los dinosaurios acorazados unicamente se conocen por restos aislados del Hauteriviense-Barremiense de Teruel. (
Follower Mindfulness and Well-Being: The Mediating Role of Perceived Authentic Leadership and the Moderating Role of Leader Mindfulness

Drawing on implicit leadership theory and the mindfulness literature, we propose that perceived authentic leadership mediates the relationship between follower mindfulness and follower well-being. Leader mindfulness plays a moderating role in this process. We validated these hypotheses with the two-wave data from 56 leaders and 275 followers in two private enterprises located in China. We used Mplus 8.0 to test our hypotheses. Consistent with our hypotheses, the results showed that perceived authentic leadership mediated the positive relationship between follower mindfulness and follower well-being. Higher leader mindfulness enhanced the effect of follower mindfulness on perceived authentic leadership and also strengthened the indirect effect of follower mindfulness on follower well-being via perceived authentic leadership. The theoretical and managerial implications are further discussed in the light of these findings.
Data Science for Weather Impacts on Crop Yield

Private businesses in sectors, such as food, energy, and retail, as well as public sector and federal agencies are interested in the predictive understanding of weather impacts on crop yield, which is an important aspect of food security. Scientific literature has mainly examined how crop yield is impacted by growing season-averaged weather indices. Although a few studies did consider weather extremes in their analysis, their scope was either restricted to measuring their conditional relationship with yield or the extreme event types considered were limited. Selection of regression models, whether the more commonly used linear approaches or nonlinear methods, have not been appropriately justified in this context. Here, we develop data-driven methods to examine two inter-related hypotheses for improved scientific understanding and enhanced predictive modeling. The first hypothesis, that extreme weather indices have a statistically significant information content in them is found to be valid based on linear and nonlinear methods for pairwise dependence. The second hypothesis, examines the value addition of nonlinear regression methods, and suggests that linear approaches may not alone be adequate. The results of this study can inform scientific understanding, generation and relevance of indices and end-to-end risk assessment systems in the context of climate impacts on crop yield. An immediate application may be in the context of NASA Earth Exchange (NEX) which facilitates the generation and dissemination of impacts relevant weather data and indices using a multitude of satellite-derived data sets and model outputs.
Hospital disinfection and antibiotic policies.

A disinfectant policy should provide information on all types of disinfectants and on procedures for their use. Requirements for chemical disinfection are mainly limited to cleaning areas of contaminated spillage, decontamination of certain heat-labile instruments e.g. fiberscopes, and disinfection of the skin. Antibiotic policies are necessary to ensure rationalization of therapy, to prevent the emergence of resistance, to limit or control the use of toxic agents and avoid the unnecessary use of costly agents. Hospitals should provide a list of freely available antibiotics and introduce varying restrictions on others. A short guide to therapy, especially prophylaxis, should be provided for the medical staff.
Multiplex family with GAD65-Abs neurologic syndromes

Objective: Neurologic autoimmune syndromes associated with anti–glutamate acid decarboxylase 65 antibodies (GAD65-Abs) are rare and mostly sporadic. Methods: We describe a niece and her aunt with GAD65-Abs neurologic syndromes. High-resolution HLA typing of Class I and Class II alleles was performed using next-generation sequencing. Results: The proband had cerebellar ataxia and probable limbic encephalitis features, whereas her niece had stiff-person syndrome. Both had a high titer of GAD65-Abs in serum and CSF and showed signs of inflammation in CSF. Both affected members carried the same rare recombinant DRB1*15:01:01∼DQA1*01:02:01∼DQB1*05:02:01 haplotype, which may or may not be involved in disease susceptibility. Of interest, other unaffected members of the family either had the same HLA haplotype but normal serum GAD65-Abs or had different HLA types but a high titer of serum GAD65-Abs without neurologic symptoms, suggesting cumulative effects. Conclusions: This unique association strengthens the concept that hereditary factors, possibly including specific HLA haplotypes, play a role in neurologic syndromes associated with GAD65-Abs.
Absence and Presence of Human Interaction: The Relationship Between Loneliness and Empathy

Loneliness is the negative experience of a discrepancy between the desired and actual personal network of relationships. Whereas past work have focused on the effect of loneliness on prosocial behaviors, the present research addressed the gap by exploring the effect of loneliness on empathy. Empathy is the emotional reaction of sharing in others’ internal experiences. We adopted a new paradigm-empathy selection task, which uses free choices to assess the desire to empathize. Participants made a series of binary choices, selecting situations that instructed them to empathize or objectively describe. Results from two studies showed that, compared to non-lonely people, lonely people were more likely to choose positive empathy but to avoid negative empathy. The pattern occurs because lonely people perceived higher (vs. lower) social support in the positive (vs. negative) empathy tasks. Moreover, empathy served to be an adaptive emotion regulation strategy developed by lonely people to reduce their loneliness effectively. This research has resulted in both theoretical contributions to prosocial behavior literature and the further discovery of practical implications for loneliness intervention.
Shifts in the Fecal Microbial Community of Cystoisospora suis Infected Piglets in Response to Toltrazuril

The protozoan parasite Cystoisospora suis causes diarrhea and reduced weight gain in suckling piglets. Infections occur in the first days of life; it is transient but can lead to dysbiosis, exacerbating disease and increasing mortality. Cystoisosporosis is effectively controlled by toltrazuril treatment; however, alterations of the gut microbial composition upon infection and treatment have not been investigated. This study evaluated the development of fecal microbiota of C. suis infected piglets in response to treatment with toltrazuril. Thirty-eight conventional piglets were infected with C. suis on the first day of life (dol 1). Twenty-six of them received either parenteral or oral toltrazuril 2 days later. Fecal samples were collected pre- and post-weaning (dol 1–15 and 31–38) for microbiota analysis using 16S rRNA amplicon sequencing and during dol 5–18 to determine fecal consistency and parasite excretion. All control animals shed parasites at least once and the majority developed diarrhea, while toltrazuril-treated piglets did not excrete parasites and only had low levels of diarrhea. Age-related shifts in the fecal microbiota composition and increase in diversity and species richness were seen until after weaning. Parasite infection disrupted bacterial maturation 2 weeks after infection. Irrespective of the route of administration, fecal communities of piglets in the treated groups clustered separately and were more diverse compared to that of control piglets during the acute phase of infection on dol 11. Control piglet feces showed higher levels of Fusobacteriaceae and Veillonellaceae, while Ruminococcaceae, Lachnospiraceae, S24-7, Clostridiaceae, and Erysipelotrichaceae were more abundant in feces of treated piglets on dol 11. Thereafter, treatment-related effects on the microbial communities were small and mainly detectable on dol 34 (5 days post-weaning), potentially indicating that the oral toltrazuril treatment might have had long-term effects on host physiological responses post-weaning. Irrespective of the administration route, toltrazuril prevented C. suis-related dysbiosis and maintained species richness and diversity on dol 11. In addition to cystoisosporosis prevention, toltrazuril seems to contribute to the stabilization of the gut microbial development during the suckling phase and thus may reduce the need for antibiotics to control infections with secondary bacterial enteropathogens in C. suis-infected suckling piglets.
Effets cytoxiques et phénotypiques de l'uranium et du plomb sur des modèles cellulaires ostéoblastiques

Cette etude s'inscrit dans le cadre de l'evaluation du danger biologique lie a l'utilisation de l'uranium dans les activites nucleaires industrielles et de recherche. L'uranium, reconnu dans la litterature comme potentiellement cancerogene ou toxique pour la reproduction, peut devenir un probleme de sante publique aux vues des diverses possibilites de contaminations humaines (militaires de la guerre du Golfe, populations finlandaises exposees a une eau de boisson contaminee par exemple). Le squelette represente l'organe de stockage a long terme de l'uranium et peut etre une cible de sa toxicite. Le plomb partage ce mode de fixation dans la matrice osseuse et aura les memes effets nefastes sur la formation osseuse. Les osteoblastes, cellules responsables dans la formation osseuse, sont des cibles particulieres de ces deux metaux. Cette etude a consiste a evaluer les effets d'une toxicite aigue de speciations controlees de l'uranium et du plomb sur de osteoblastes en culture. L'accumulation, la repartition et la speciation intracellulaires ont ensuite ete etudies afin d'expliquer les toxicites observees. Une mortalite cellulaire et un desordre phenotypique ont ete mis en evidence. La speciation est apparue comme determinante des effets biologiques de ces metaux. Les especes les plus toxiques de ces deux metaux ont pu etre identifiees. L'accumulation ou la repartition cellulaire n'ont pu expliquer a eux seuls l'impact de la speciation sur la toxicite observee. Cependant, un phenomene de precipitation intracellulaire de l'uranium comme du plomb a ete mis en evidence et pourrait etre implique dans un mecanisme de detoxication.
Structured Inspections of Search Interfaces: A Practitioners Guide

In this paper we present a practitioners guide on how to apply a new inspection framework that evaluates search interfaces for their support of different searcher types. Vast amounts of money are being invested into search, and so it is becoming increasingly important to identify problems in design early, while it is relatively cheap to rectify them. The inspection method presented here can be applied quickly to early prototypes, as well as existing systems, and goes beyond other inspection methods, like Cognitive Walkthroughs, to produces rich analyses, including the support provided for different search tactics and user types. The guide is presented as a detailed example, assessing a previously unevaluated search interface: the Tabulator, and so also provides design recommendations for improving it. We conclude with a summary of the benefits of the evaluation framework, and discuss our plans for future enhancements.
Vascular invasion in breast cancer; an overview of recent prognostic developments and molecular pathophysiological mechanisms

Vascular invasion (VI) is an essential step in breast cancer metastasis and the main cause of morbidity and mortality from the disease. Detection of VI in the primary tumour is a marker of metastatic potential. The prognostic value of VI in breast cancer has been known for more than four decades, but its application in clinical practice is still fraught with difficulties due to the limited number of studies conducted on large numbers of well‐characterized patients with long‐term follow‐up. Detection of VI in the primary tumour is currently assessed using sections stained with haematoxylin and eosin, which has some disadvantages. A number of vascular markers have been used to improve detection of VI; however, their sensitivity and specificity, as endothelial markers, vary considerably. In this review we describe the evolution of the prognostic importance of VI and the recent pathomolecular mechanisms that contribute to the ability of breast cancers to invade through vessels, in addition to the types, locations and methods of detection of vascular invasion.
Reproducibility of proton MR spectroscopic imaging (PEPSI): comparison of dyslexic and normal-reading children and effects of treatment on brain lactate levels during language tasks.

BACKGROUND AND PURPOSE We repeated a proton echo-planar spectroscopic imaging (PEPSI) study to test the hypothesis that children with dyslexia and good readers differ in brain lactate activation during a phonologic judgment task before but not after instructional treatment. METHODS We measured PEPSI brain lactate activation (TR/TE, 4000/144; 1.5 T) at two points 1-2 months apart during two language tasks (phonologic and lexical) and a control task (passive listening). Dyslexic participants (n = 10) and control participants (n = 8) (boys and girls aged 9-12 years) were matched in age, verbal intelligence quotients, and valid PEPSI voxels. In contrast to patients in past studies who received combined treatment, our patients were randomly assigned to either phonologic or morphologic (meaning-based) intervention between the scanning sessions. RESULTS Before treatment, the patients showed significantly greater lactate elevation in the left frontal regions (including the inferior frontal gyrus) during the phonologic task. Both patients and control subjects differed significantly in the right parietal and occipital regions during both tasks. After treatment, the two groups did not significantly differ in any brain region during either task, but individuals given morphologic treatment were significantly more likely to have reduced left frontal lactate activation during the phonologic task. CONCLUSION The previous finding of greater left frontal lactate elevation in children with dyslexia during a phonologic judgment task was replicated, and brain activation changed as a result of treatment. However, the treatment effect was due to the morphologic component rather than the phonologic component.
Identification of Lactoferrin gene Polymorphism and its association with Mastitis incidence

Present study was conducted in total of 350 cows of two major dairy breeds (Sahiwal and Karan Fries) with the aim to identify genetic variation in lactoferrin gene promoter and to study its association with incidence of mastitis. Polymorphism of bovine lactoferrin gene promoter was determined by using restriction fragment length polymorphism (PCR-RFLP). Lactorferrin gene promoter was polymorphic but showed varied level of polymorphism among Sahiwal and Karan Fries cattle. Three genotypes were identified viz. AA, AB and BB in Karan Fries cattle and two genotypes AA and AB in Sahiwal cattle. BB genotype was absent in Sahiwal herd of National Dairy Research Institute, Karnal. Chi square test revealed a nonsignificant association (pd≤0.05) with mastitis incidence.
Handling Updates in Ontology-based Data Access

Ontology-based Data Access (OBDA) is gaining importance both scientifically and practically. However, little attention has been paid so far to the problem of updating OBDA systems. This is an essential issue if we want to be able to cope with modifications of data both at the ontology and at the source level, while maintaining the independence of the data sources. In this paper, we propose mechanisms to properly handle updates in this context. We show that updating data both at the ontology and source level is first-order rewritable. We also provide a practical implementation of such updating mechanisms based on non-recursive
A high-speed high-resolution low-phase noise oscillator using self-timed rings

A high-speed multi-phase oscillator based on self-timed ring is proposed. Self-timed rings (STR) are promising approach for designing high-speed serial links and clock generators. Indeed, the architecture of STR allows us to achieve high frequencies with multiphase outputs and their oscillation frequency is not only depending on the number of stages but also on the initial state of the ring. Moreover, this architecture allows us 3 dB phase noise reduction when, while keeping the same frequency, when the stage number is doubled. In this paper, we propose a method to design STR able to generate high-speed multi-phase outputs and we suggest a design flow for designing low-phase noise self-timed ring oscillators. All the electrical simulations and results have been performed using a CMOS 65nm technology from STMicroelectronics.

Historical Data Reveal 30-Year Persistence of Benthic Fauna Associations in Heavily Modified Waterbody

Baseline surveys form the cornerstone of coastal impact studies where altered conditions, for example through new infrastructure development, are assessed against a temporal reference state. They are snapshots taken before construction. Due to scarcity of relevant data prior to baseline surveys long-term trends can often not be taken into account. Particularly in heavily modified waterbodies this would however be desirable to control for changes in anthropogenic use over time as well as natural ecological variation. Here, the benthic environment of an industrialized embayment was investigated (Swansea Bay, Wales, UK) where it is proposed to build a tidal lagoon that would generate marine renewable energy from the tidal range. Since robust long-term baseline data was not available, the value of unpublished historical benthos information from 1984 by a regional water company was assessed with the aim to improve certainty about the persistence of current benthic community patterns. A survey of 101 positions in 2014 identified spatially discrete benthic communities with areas of high and low diversity. Habitat characteristics including sediment properties and the proximity to a sewage outfall explained 17-35% of the variation in the community structure. Comparing the historical information from 1984 with 2014 revealed striking similarity in the benthic communities between those years, not just in their spatial distribution but also to a large extent in the species composition. The 30-year-old information confirmed spatial boundaries of discrete species associations and pinpointed a similar diversity hotspot. A group of five common species was found to be particularly persistent over time (Nucula nitidosa, Spisula elliptica, Spiophanes bombyx, Nephtys hombergii, Diastylis rathkei). According to the Infauna Quality Index (IQI) linked to the EU Water Framework Directive (WFD) the average ecological status for 2014 was ‘moderate’, but eleven samples showing ‘poor’ and ‘bad’ status indicated possible negative impacts of dredge spoil disposal. Generally the study demonstrated the value of historical information for assessing the persistence of benthic community characteristics, while also highlighting shortcomings if raw data is lost and if the historical baseline does not reflect pristine ecological conditions.
Perceived barriers to anthropometric measurements in critically ill children.

BACKGROUND Anthropometric measurements are vital for safe care in pediatric intensive care units. OBJECTIVE To identify barriers to anthropometric measurements and determine if perceptions of barriers differ between ordering providers and nurses. METHODS A 21-item survey to elicit perceptions of barriers to obtaining anthropometric measurements was distributed via e-mail to societies with members who provide care in pediatric intensive care units. RESULTS Most of the 258 eligible respondents (46% ordering providers) were from North America (90%). Although 84% agreed that anthropometric measurements are important, only 3% knew if these measurements were obtained upon admission to their unit. Estimates of patients' measurements by parents or caregivers were commonly used (72%) when actual measurements were not obtained. Leading barriers were presence of medical devices (57%), use of extracorporeal life support (54%), and unstable hemodynamic status (52%). More ordering providers than nurses considered osteopenia/fragile bones as a barrier to weight measurement (46% vs 29%; P = .007) and traumatic brain injury a barrier to measurement of head circumference (42% vs 24%; P = .002). More nurses than ordering providers perceived dialysis (21% vs 9%; P = .01) and obesity (26% vs 15%; P = .04) as barriers to measurement of stature. Ordering providers more than nurses perceived nurses' workload (51% vs 33%; P < .001) and lack of importance (43% vs 20%; P < .001) as barriers. CONCLUSIONS Barriers to obtaining anthropometric measurements exist in pediatric intensive care units; ordering providers and nurses have different perceptions of what constitutes a barrier.
