Nanopetrophysical characterization of the Mancos Shale Formation in the San Juan Basin of northwestern New Mexico, USA
Authors: Hu Qinhong , Kalteyer Richard , Wang Jingyi , El-Sobky Hesham F. 
Published: August 2019

The Mancos Shale of the San Juan Basin has been an important resource for the exploration and development of oil and gas. However, as with most unconventional plays, the shales have low porosity and extremely low permeability with predominantly nanometer-sized pores. Thus, it is critical to understand the nanopetrophysical properties of the reservoir so a proper assessment of the reservoir quality can be made. Working with three as-received core samples from three different wells of the Tacito Marine Bar and Offshore Mancos play types, we have developed an initial understanding of the nanopetrophysical properties of the pore structure as well as fluid-rock interactions in these tight reservoirs. We have performed a suite of integrated tests, such as mercury intrusion porosimetry (MIP), low-pressure nitrogen physisorption, core plug porosity and permeability, scanning electron microscopy imaging, water immersion porosimetry after vacuum pulling, contact angle, and fluid imbibition. In addition, we obtained supplementary data for total organic carbon, X-ray diffraction, and pyrolysis to further evaluate reservoir quality. The Mancos Shale samples exhibit petrophysical characteristics that are controlled by a predominant presence of nanometer-sized pore space, with 56%–96% pore volumes present as 3.4–50 nm in pore-throat sizes, as shown by the MIP approach. Contact angle and fluid imbibition tests demonstrate that samples are oil wet to mixed wet, with a tendency of pore networks to imbibe oil over water. The findings from integrated pore structure and wettability studies provide a database and some insights, from the perspectives of nanopetrophysical characterization, into the reservoir quality of the Mancos Shale.

PURPOSE To report the results of a phase II clinical trial of de-intensified chemoradiotherapy for patients with human papillomavirus–associated oropharyngeal squamous cell carcinoma. MATERIALS AND METHODS Major inclusion criteria were (1) having American Joint Committee on Cancer (AJCC) 7th edition T0-T3, N0-N2c, M0 (AJCC 8th edition T0-T3, N0-N2, M0), (2) being p16 positive, and (3) reporting minimal or remote smoking history. Treatment was limited to 60 Gy intensity-modulated radiotherapy with concurrent intravenous cisplatin 30 mg/m2 once per week. Patients with T0-T2 N0-1 (AJCC 7th edition) did not receive chemotherapy. All patients had a 10- to 12-week post-treatment positron emission tomography/computed tomography to assess for neck dissection. The primary end point was 2-year progression-free survival. Secondary end points included 2-year local-regional control, distant metastasis-free survival and overall survival, and patient-reported outcomes (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire and the patient-reported outcomes version of the Common Terminology Criteria for Adverse Events). RESULTS One hundred fourteen patients were enrolled (median follow-up of 31.8 months), with 81% having a minimum follow-up of 2 years. Eighty percent of patients had 10 or fewer tobacco pack-years. Two-year local-regional control, distant metastasis-free survival, progression-free survival, and overall survival were as follows: 95%, 91%, 86%, and 95%, respectively. Mean pre- and 2-year post-treatment European Organisation for Research and Treatment of Cancer quality of life scores were as follows: global, 79/84 (lower worse); swallowing, 8/9 (higher worse); and dry mouth, 14/45 (higher worse). Mean pre- and 2-year post-treatment patient-reported outcomes version of the Common Terminology Criteria for Adverse Events scores (0 to 4 scale, higher worse) were as follows: swallowing, 0.5/0.7, and dry mouth, 0.4/1.3. Thirty-four percent of patients required a feeding tube (median, 10.5 weeks; none permanent). There were no grade 3 or higher late adverse events. CONCLUSION Clinical outcomes with a de-intensified chemoradiotherapy regimen of 60 Gy intensity-modulated radiotherapy with concurrent low-dose cisplatin are favorable in patients with human papillomavirus–associated oropharyngeal squamous cell carcinoma. Neither neoadjuvant chemotherapy nor routine surgery is needed to obtain favorable results with de-escalation.

Published: August 2019

Background: Central to the successful elimination of Plasmodium falciparum malaria, are tests with superior capability of diagnosing low-density parasitaemias. Empirical evidence on the performance of the commonly available diagnostics (light microscopy (LM), rapid diagnostic tests (RDT) and polymerase chain reaction (PCR)) is needed to better inform case management and surveillance activities within primary health care settings where elimination of falciparum malaria is targeted. The objective of this study was to estimate the sensitivity (Se) and specificity (Sp) and predictive values of LM, RDT and PCR tests for P. falciparum infection in children, while evaluating the effect of specific covariates on the accuracy of the tests. Methods: The study enrolled 1,563 children presenting with fever (axillary temperature ≥ 37.50C) to the Ngerenya dispensary, Kilifi County between March and December 2014. A Bayesian latent class model (BLCM) was fitted to the participants’ diagnostic data obtained from blood samples that were screened for the presence of P. falciparum using the three tests. Results: The PCR assay registered a higher Se (97.6% [92.0; 99.7]) than LM (84.0% [74.8; 91.0]) but similar to RDT (92.2% [84.4; 97.0]). However, the assay showed a similar Sp (98.9% [98.2; 99.4]) to both RDT (99.4% [98.9; 99.7]) and LM (99.5% [99.0; 99.8]). Regarding predictive values, the tests yielded statistically similar estimates of positive and negative predictive values (PPV and NPV). A serial interpretation of the results of RDT and LM raised the PPVs and NPVs to >98%. Conclusions: LM and RDT afford high Se and Sp in a low P. falciparum prevalence setting. A serial combination of the tests assures high PPV and NPV estimates. These elements, coupled with the wide deployment and affordability of the tests, lend the tests useful for guiding clinical care and surveillance activities for P. falciparum within elimination settings.

Objective: Evaluate and compare the antimicrobial efficacy of four different commercially available children’s toothpastes on bacteria growth inhibition from oral microbiota of young children. Material and Method: The toothpastes tested contained: 1100 ppm sodium fluoride, xylitol and 750 ppm sodium fluoride, xylitol and 500 ppm sodium fluoride, and xylitol and triclosan. Twenty 18 to 30 month-old children were selected. Nonstimulated saliva samples were collected and inoculated on brain heart infusion (BHI) agar. Toothpaste dilutions were applied into the agar wells and incubated at 37ºC for 24 hours in microaerophilic conditions. Saline and 0.12% chlorhexidine were used as controls. Antimicrobial activity was determined in duplicate by agar-well diffusion technique. Bacterial growth inhibition zones were recorded in mm. Statistical analysis was performed using ANOVA and Tukey's test (p<0.05). Results: All toothpastes showed antimicrobial activity when compared to negative control (p<0.05). Toothpaste containing triclosan presented the highest antimicrobial activity followed, in this order, by xylitol and 750 ppm sodium fluoride, chlorhexidine, 1100 ppm sodium fluoride, xylitol and 500 ppm sodium fluoride and saline. Conclusions: Toothpaste containing triclosan and xylitol presented excellent antimicrobial activity, and may be considered a good option for young children.Key words: Toothpastes. Oral hygiene.

Überblick
Pastoraltheologie kann nicht mehr allein aufs Pfarramt fokussiert werden, sie ist vielmehr als Theorie kirchlicher Berufe zu entwickeln. Empirische Erkenntnisse wie kirchentheore­tisch-normative Überlegungen sprechen dafür, das Miteinander kirchlicher Berufe verstärkt in den Blick zu nehmen, um den differenzierten Aufgaben der Kirche gegenwärtig gerecht werden zu können. Aus der Analyse aktueller Kirchenreformprozesse ergibt sich ein Plädoyer für die stärkere Berücksichtigung »multiprofessioneller Teams«.

In this study the potential bioinseticide of the essential oil (OE) extracted from the rhizomes of the species Curcuma zedoaria (Zingiberaceae) was evaluated. The rhizomes were collected during dormancy (winter) and budding (summer). The EO was obtained by hydrodistillation (2h) and identified by GC/MS. In addition, a multivariate exploratory analysis was done to determine the analysis of the major compounds (PCA). The EO yield in dormancy was 0.61± 0.07 (%) and in budding 0.55 ± 0.08 (%). The bioassays on Aedes aegypti larvae and pupae were done by immersion test at different EO concentrations which ranged from 500.00 to 0.003 mg mL-1 (v/v). The results on the larvae and pupae indicated LC99.9 of (0.01 and 1.38 mg mL-1) for EO in dormancy, and (0.08 and 2.63 mg mL-1) for EO during budding, respectively. The action mechanism of EOs in both periods was determined by autobiographic method evaluating the inhibitory potential on the acetylcholinesterase enzyme, indicating greater inhibition of the EO enzyme during dormancy (0.039 mg mL-1) when compared to the EO during budding (0.156 mg mL-1). The projection representation of the EO chemical classes in both evaluated periods indicated that oxygenated sesquiterpenes are the major compound class (46.99% in dormancy) and (43.59% in budding). The projection of major chemical compounds of EOs presented three compounds with greater mass flow distancing: epicurzerenone (18.20% and 12.10%); 1.8 cineole (15.76% and 12.10%) and β-elemene (4.43 and 0.01%) that are found in greater amounts in the dormancy EO when compared to budding, respectively. These results corroborate with the greater potential on Ae. aegypti larvae and pupae found for the dormancy EO. The results are promising because they show in which vegetative cycle phase C. zedoaria EO presents greater bioinsecticide potential.

Published: August 2019

Several methodologies have been proposed in order to measure the influence that genotype-by-environment interaction exerts on the various characters of interest. The mixed models using REML/BLUP and GGE Biplot have been mentioned as advantageous to identify superior genotypes. The use of environmental information can be useful to find the factors that are in the real difference between the genotypes. The objective of this study was to compare statistical methodologies for the adaptability and stability analysis of cowpea genotypes in value for cultivation and use testings. The experiments were carried out from March to July 2016 and 2017, in the municipalities of Dourados and Aquidauana. A randomized complete block design was used, with 14 genotypes and four replicates, 12 advanced lines and two commercial cultivars. After detecting significant genotype-by-environment interaction, the adaptability and phenotypic stability of cowpea genotypes were analyzed by the GGE Biplot and REML/BLUP. Both methodologies were concordant in the identification of the best cowpea genotypes for the State of Mato Grosso do Sul. The genotypes 6 (Pingo-de-ouro 1-5-4), 10 (Pingo-de-ouro 1-5-10) and 8 (Pingo-de-ouro 1-5-7) are the most suitable to be grown in the State, because they have gathered high grain yield, adaptability and stability.

Published: August 2019

Abstract
The Cauchy problem of nonlinear Schrödinger equation with a harmonic potential for describing the attractive Bose-Einstein condensate under the magnetic trap is considered. We give some sufficient conditions of global existence and finite time blow up of solutions by introducing a family of potential wells. Some different sharp conditions for global existence, and some invariant sets of solutions are also obtained here.
Beilinson–Flach elements, Stark units and 𝑝-adic iterated integrals
Authors: Rivero Óscar , Rotger Victor 
Published: August 2019

Abstract
We study weight one specializations of the Euler system of Beilinson–Flach elements introduced by Kings, Loeffler and Zerbes, with a view towards a conjecture of Darmon, Lauder and Rotger relating logarithms of units in suitable number fields to special values of the Hida–Rankin p-adic L-function. We show that the latter conjecture follows from expected properties of Beilinson–Flach elements and prove the analogue of the main theorem of Castella and Hsieh about generalized Kato classes.

On equidistant lines of given line configurations
Authors: Kuwata Takayasu , Maehara Hiroshi , Martini Horst 
Published: August 2019

AbstractThe equidistant set of a collectionFof lines in 3-space is the set of those points whose distances to the lines inFare all equal. We present many examples and results related to the lines possibly contained in the equidistant set ofF. In particular, we determine the possible numbers of lines in the equidistant set of a collection ofnlines for everyn>0{n>0}. For example, ifn=3{n=3}, then the possible number of such lines is either 4 or 2 or 1 or 0. In a natural way, our results are connected with properties of special types of (ruled) surfaces. For example, we obtain also results on the number of lines in the intersection of quadratic surfaces.

Some improved bounds on two energy-like invariants of some derived graphs
Authors: Cui Shu-Yu , Tian Gui-Xian 
Published: August 2019

Abstract
Given a simple graph G, its Laplacian-energy-like invariant LEL(G) and incidence energy IE(G) are the sum of square root of its all Laplacian eigenvalues and signless Laplacian eigenvalues, respectively. This paper obtains some improved bounds on LEL and IE of the 𝓡-graph and 𝓠-graph for a regular graph. Theoretical analysis indicates that these results improve some known results. In addition, some new lower bounds on LEL and IE of the line graph of a semiregular graph are also given.

A computational investigation of the optimal Halton sequence in QMC applications
Authors: Bayousef Manal , Mascagni Michael 
Published: August 2019

Abstract
We propose the use of randomized (scrambled) quasirandom sequences for the purpose of providing practical error estimates for quasi-Monte Carlo (QMC) applications.
One popular quasirandom sequence among practitioners is the Halton sequence.
However, Halton subsequences have correlation problems in their highest dimensions, and so using this sequence for high-dimensional integrals dramatically affects the accuracy of QMC.
Consequently, QMC studies have previously proposed several scrambling methods; however, to varying degrees, scrambled versions of Halton sequences still suffer from the correlation problem as manifested in two-dimensional projections.
This paper proposes a modified Halton sequence (MHalton), created using a linear digital scrambling method, which finds the optimal multiplier for the Halton sequence in the linear scrambling space.
In order to generate better uniformity of distributed sequences, we have chosen strong MHalton multipliers up to 360 dimensions.
The proposed multipliers have been tested and proved to be stronger than several sets of multipliers used in other known scrambling methods.
To compare the quality of our proposed scrambled MHalton sequences with others, we have performed several extensive computational tests that use

L

{L_{2}}

-discrepancy and high-dimensional integration tests.
Moreover, we have tested MHalton sequences on Mortgage-backed security (MBS), which is one of the most widely used applications in finance.
We have tested our proposed MHalton sequence numerically and empirically, and they show optimal results in QMC applications.
These confirm the efficiency and safety of our proposed MHalton over scrambling sequences previously used in QMC applications.
