Nonperturbative-transverse-momentum broadening in dihadron angular correlations in sNN =200 GeV proton-nucleus collisions

The PHENIX collaboration has measured high-pT dihadron correlations in p+p, p+Al, and p+Au collisions at sNN=200 GeV. The correlations arise from inter- and intrajet correlations and thus have sensitivity to nonperturbative effects in both the initial and final states. The distributions of pout, the transverse-momentum component of the associated hadron perpendicular to the trigger hadron, are sen

American geography of opportunity reveals European origins

A large literature documents how intergenerational mobility—the degree to which (dis)advantage is passed on from parents to children—varies across and within countries. Less is known about the origin or persistence of such differences. We show that US areas populated by descendants to European immigrants have similar levels of income equality and mobility as the countries their forebears came from

Pretreatment with P2Y12 receptor antagonists in ST-elevation myocardial infarction : a report from the Swedish Coronary Angiography and Angioplasty Registry

AIMS: Pretreatment of patients with ST-elevation myocardial infarction (STEMI) with P2Y12 receptor antagonists is supported by guidelines and is a common practice despite the lack of definite evidence for its benefit. METHODS AND RESULTS: Using data from the Swedish Coronary Angiography and Angioplasty Registry on procedures between 2005 and 2016, we stratified all patients who underwent primary p

Mn IV -Oxo complex of a bis(benzimidazolyl)-containing N5 ligand reveals different reactivity trends for Mn IV -oxo than Fe IV -oxo species

Using the pentadentate ligand (N-bis(1-methyl-2-benzimidazolyl)methyl-N-(bis-2-pyridylmethyl)amine, 2pyN2B), presenting two pyridyl and two (N-methyl)benzimidazolyl donor moieties in addition to a central tertiary amine, new Mn II and Mn IV -oxo complexes were generated and characterized. The [Mn IV (O)(2pyN2B)] 2+ complex showed spectroscopic signatures (i.e., electronic absorption band maxi

Simulating beach and dune evolution at decadal to centennial scale under rising sea levels

A numerical model for simulating beach-dune evolution at decadal to centennial time scales is developed. The work builds on an existing semi-empirical cross-shore model, the CS-model, to which the effect of sea level rise is added and the routines for aeolian transport and morphological dune evolution are improved. The model development is based on established conceptual models from the literature

Some aspects on the pathophysiology of migraine and a review of device therapies for migraine and cluster headache

Migraine is a common, severe disease, affecting the brain and blood vessels, causing much pain, time missed from work and family, and severe disability. It affects approximately 12% of most Western populations studied and affects women three times more than men. Cluster headache is a much less common dysfunction of the hypothalamus, involving the sphenopalatine ganglion and other areas; it causes

Rasch analysis of the Patient Participation in Rehabilitation Questionnaire (PPRQ)

Objective: To evaluate the Patient Participation in Rehabilitation Questionnaire (PPRQ) according to Rasch measurement theory. Method: Five hundred twenty-two post-discharge patients from a neurological rehabilitation unit were included. The PPRQ questionnaire comprises 20 items rated by a cohort of 522 patients about their experiences of participating in rehabilitation. The measurement properties

The tympanic membrane and middle ear mucosa during non-typeable Haemophilus influenzae and Haemophilus influenzae type b acute otitis media : A study in the rat

Non-typeable Haemophilus influenzae (NTHi) and encapsulated Haemophilus influenzae type b (Hib) were inoculated into the middle ears of Sprague- Dawley rats. Tympanic membrane (TM) status was assessed otomicroscopically and specimens from various middle ear areas were prepared for light microscopy at various times during the acute phase and up to 6 months after inoculation. Irrespective of bacteri

Tolerance and overcompensation to infection by Phytophthora infestans in the wild perennial climber Solanum dulcamara

Studies of infection by Phytophthora infestans—the causal agent of potato late blight—in wild species can provide novel insights into plant defense responses, and indicate how wild plants might be influenced by recurrent epidemics in agricultural fields. In the present study, our aim was to investigate if different clones of Solanum dulcamara (a relative of potato) collected in the wild differ in

A Tale of Two Caterpillars and Reclassification of Cerathosia Smith and Cydosia Duncan [& Westwood] (Lepidoptera : Noctuidae)

The life histories of Cerathosia tricolor Smith and Cydosia aurivitta Grote & Robinson are briefly described and their larvae figured. Data from seven gene regions (>5,500 base pairs) as well as larval morphology suggest both moths are misclassified in Eustrotiinae and Cydosiinae, respectively: Cerathosia Smith is transferred to Stiriinae, Cydosia Duncan [& Westwood] is transferred to Meto

A rat model of otitis media with effusion caused by eustachian tube obstruction with and without Streptococcus pneumoniae infection : Methods and course

OBJECTIVE: To describe the clinical and histopathologic progression of a rat model of otitis media with effusion caused by eustachian tube obstruction (ETO) with and without Streptococcus pneumoniae infection. METHODS: In 164 rats, the left, bony eustachian tube was approached via a ventral incision and obstructed with dental material. Then 108 rats were infected via an intrabullar injection with

Towards a spatial-temporal model of prevalence of nodding syndrome and epilepsy

Nodding syndrome is an emerging disease which have unknown transmission patterns and no properly established mechanisms for diagnosis leading to numerous hypothetical postulations. It has affected thousands of children in Uganda with debilitating effect and serious economic consequences. Spatial-temporal analysis may provide a quick mechanism to establish comparative understanding of the various h

Myringosclerosis caused by increased oxygen concentration in traumatized tympanic membranes experimental study

The purpose of this study was to elucidate possible relationships between the oxygen concentration of the middle ear cavity and the development of myringosclerosis. Three groups of rats with myringotomized tympanic membranes were exposed to different oxygen concentrations of 10%, 15%, and 40%, respectively, for 1 week. A fourth group was kept in ambient air. Two other groups of rats with myringoto

A priori analysis of sub-grid variance of a reactive scalar using DNS data of high Ka flames

Direct numerical simulations (DNS) of low and high Karlovitz number (Ka) flames are analysed to investigate the behaviour of the reactive scalar sub-grid scale (SGS) variance in premixed combustion under a wide range of combustion conditions (regimes). An order of magnitude analysis is performed to assess the importance of various terms in the variance evolution equation and the analysis is valida

Myringotomy : A prerequisite for the development of myringosclerosis?

Streptococcus pneumoniae was inoculated into the left middle-ear cavity in two groups of rats, resulting in purulent otitis media. After 3 days, one group of infected animals and a third group of noninfected animals were subjected to left-sided myringotomy. The tympanic membranes were examined both otomicroscopically and histologically 1 and 3 months later. On otomicroscopic examination the noninf
