Double Higgs boson production at NLO in the high-energy limit: complete analytic results

Abstract We compute the NLO virtual corrections to the partonic cross section of gg → HH, in the high energy limit. Finite Higgs boson mass effects are taken into account via an expansion which is shown to converge quickly. We obtain analytic results for the next-to-leading order form factors which can be used to compute the cross section. The method used for the calculation of...

Tuberculosis knowledge, attitude and practice among healthcare workers during the 2016 Hajj

Background Given the inherent characteristics of the Hajj pilgrimage, the event is a risk for tuberculosis (TB) infection. Early diagnosis and appropriate management of TB cases by knowledgeable and skilled healthcare workers (HCWs) are key in improving patients’ outcome and preventing transmission during the Hajj mass gathering and globally. Method We conducted a cross-sectional...

Taxonomic comments for the new records and a dichotomous key for the 12 known species for Costa Rica are presented.

Estudo comparativo da produtividade de cinco cultivares de soja (Glycine max(L.) Merrill)

Under greenhouse conditions cultivars Davis, IAC 73-228, PI 227.687, PI 171.451, and PI 229.358 of soybean were compared. PI 171.451 showed lower dry weight of stem in relation to Davis. Higher pod numbers produced by PI 227-687, IAC 73-228, and PI 229. 358 as compared to Davis were observed. Cultivars PI 227.687 and IAC 73-228 produced larger seed numbers. A larger weight of 100...

Simultaneous ammonium and p-hydroxybenzaldehyde oxidation in a sequencing batch reactor

The simultaneous ammonium and p-hydroxybenzaldehyde (pOHBD) oxidation capacity of a nitrifying sludge was investigated in a sequencing batch reactor (SBR). At all initial pOHBD concentrations tested (25-400 mg C/L), both ammonium (100 mg NH4-+N/L) and pOHBD were consumed with efficiencies of 99.2 ± 1.5% and 100 ±t 1%, respectively. At pOHBD concentrations lower than 100 mg C/L...

Huellas de una cronogénesis: Propuesta de identificación de los murales teotihuacanos conocidos como "estructuras arquitectónicas

This article analyses a sample consisting of four murals at Teotihuacan-early pieces characterized by their high degree of abstraction. Arthur Miller was the first to find a common discourse running through these pieces, which since then have entered the catalogues under the title of "architectural motifs". This article offers a new interpretation of the represented scenes...

El español de América a la luz de sus contactos con el mundo indígena y el europeo

In this article we propose a model to analyze the spanish language and culture in the Americas that focuses on language and cultural contact as they coexisted in the New World since earlier times. We design this model taking into consideration sociolinguistic elements and the semiotic theory of Mikhail Bakhtin’s dialogism and its key concepts of utterance, chronotope and alterity.

Grain growth in polycrystalline Ba0,5Sr0,5TiO3 ceramics prepared at different sintering times

A grain size study based on the measurements of the maximum permittivity and the microstructure of samples of Sr0,5Ba0,5TiO3 sintered at different time lengths at a fixed temperature is reported. A linear law of grain growth is found from the experimental results and properly described by the Johnson-Mehl-Avrami theory. The model predicts a zero nucleation rate.

Epidemiology of coronary artery disease and stroke and associated risk factors in Gaza community –Palestine

Aim of study To determine the prevalence of cardiovascular disease and associated risk factors in the population of Gaza strip in Palestine. Methods A cross-sectional stratified cluster sample design was applied in this study. A sample of 2240 participant (1121 males and 1119 females) aged ≥25 years participated in the study. For each individual, trained staff administered a...

Creation theology in Psalm 139

The first reference in the Bible to God's activities is "in the beginning, God created. " This puts "Creator" at the top of the list of descriptions of who Yahweh is and what Yahweh does. This implies that Yahweh stands in relationship with the world, and not only with Israel. Israel was created to be his people as a result of him being the Creator of the world. He is therefore...

Was beeinflusst die antiemetische Wirkung eines NK-1-Rezeptor-Hemmers?

Der Neurokinin-1(NK-1)-Rezeptor-Antagonist Fosaprepitant verbesserte in einer Phase-III-Studie die Prävention von Übelkeit und Erbrechen (CINV) bei Patienten mit mäßig emetogener Chemotherapie (MEC). In der Post-hoc-Analyse bestätigte sich, dass mit einer Einzeldosis von Fosaprepitant auch in den verschiedenen Subgruppen ein gutes Ansprechen erzielt werden kann.

Deletion of the p16INK4a tumor suppressor and expression of the androgen receptor induce sarcomatoid carcinomas with signet ring cells in the mouse prostate

The tumor suppressor p16Ink4a, encoded by the INK4a gene, is an inhibitor of cyclin D-dependent kinases 4 and 6, CDK4 and CDK6. This inhibition prevents the phosphorylation of the retinoblastoma protein (pRb), resulting in cellular senescence through inhibition of E2F-mediated transcription of S phase genes required for cell proliferation. The p16Ink4a plays an important role in...

Free-Standing Selenium Impregnated Carbonized Leaf Cathodes for High-Performance Sodium-Selenium Batteries

A novel approach of carbonizing leaves by thermal pyrolysis with melt diffusion followed by selenium vapor deposition is developed to prepare the carbon-selenium composite cathodes for sodium-selenium batteries. The carbonized leaf possesses internal hierarchical porosity and high mass loading; therefore, the composite is applied as a binder- and current collector-free cathode...

Ação, fundação e autoridade em Hannah Arendt

Thirty years after Hannah Arendt’s death, the author is considered one of the best political theorists of the 20th century. Hannah Arendt main contribution to political theory is her concept of action and its role in the redefinition of the political realm, in particular, the way it has inserted the idea of new beginning into modern politics. Many authors have already pointed out...

Clinical performance of Anyplex II HPV28 by human papillomavirus type and viral load in a referral population

Anyplex II HPV28 (`Anyplex`) is a semi-quantitative DNA PCR assay divided into set A, comprising 14 high risk (hr)HPV types; and set B, comprising 5 possibly hrHPV types and 9 low risk (lr)HPV types. We compared the ability of Anyplex to that of Hybrid Capture 2 (HC2) and PreTect HPV-Proofer (`Proofer`) to detect cervical intraepithelial neoplasia grade two or worse (CIN2+) by...

The Weathering Hypothesis: Sociocultural and Biological Factors of Postpartum Depression Among Black Women

Black women experience higher rates of PPD than their White counterparts. To date, no one has linked experiences of racism and discrimination, the impacts racism and discrimination have on allostatic load, and the subsequent process of weathering to the elevated levels of PPD in Black women. However, the Weathering Hypothesis can be utilized to explain the higher rates of PPD...
