Authors: Savchuk Stepan , Khoptar Alina 
Published: June 2019

AbstractGlobal Navigation Satellite Systems give opportunities for atmospheric parameters analysis in behalf of solving many atmosphere monitoring tasks. The authors of this article demonstrated possibility of slant tropospheric delays determination with using precise point positioning method – PPP. The atmospheric parameters, retrieved from GNSS observations, including zenith tropospheric delays, horizontal gradients, and slant tropospheric delays, are analyzed and evaluated. It was obtained slant tropospheric delays, along the satellite path, for each satellite, at a certain elevation angle and azimuth, at each time, instead of obtaining a single zenith tropospheric delay composed of all visible satellites at one time. The results obtained proved that suggested method was correct.
Analogy-Based Approaches to Improve Software Project Effort Estimation Accuracy
Authors: Resmi V , Vijayalakshmi S 
Published: June 2019

Abstract
In the discipline of software development, effort estimation renders a pivotal role. For the successful development of the project, an unambiguous estimation is necessitated. But there is the inadequacy of standard methods for estimating an effort which is applicable to all projects. Hence, to procure the best way of estimating the effort becomes an indispensable need of the project manager. Mathematical models are only mediocre in performing accurate estimation. On that account, we opt for analogy-based effort estimation by means of some soft computing techniques which rely on historical effort estimation data of the successfully completed projects to estimate the effort. So in a thorough study to improve the accuracy, models are generated for the clusters of the datasets with the confidence that data within the cluster have similar properties. This paper aims mainly on the analysis of some of the techniques to improve the effort prediction accuracy. Here the research starts with analyzing the correlation coefficient of the selected datasets. Then the process moves through the analysis of classification accuracy, clustering accuracy, mean magnitude of relative error and prediction accuracy based on some machine learning methods. Finally, a bio-inspired firefly algorithm with fuzzy analogy is applied on the datasets to produce good estimation accuracy.

Abstract
Parenteral options for treating neonatal hypoglycemia (NH) include: intramuscular (i.m.) glucagon or intravenous (i.v.) glucose 10%. So far, the role of i.m. glucagon in treating NH has not been adequately assessed. We retrospectively studied 236 neonates with NH. One hundred and twenty-one infants received oral glucose-fortified-milk-based formula (OGFM) and their blood glucose level (BGL) was maintained thereafter. Two groups of infants required intervention: (a) OGFM + i.m. glucagon (n = 77, 32.6%) and (b) OGFM + i.v. glucose bolus (n = 38, 16.1%). BGL1, BGL2 and BGL3 denote pre-treatment BGL, 2–2.5 h post-treatment and BGL within 2.5–4 h post-treatment; respectively. The two groups were compared regarding two outcome measures: Outcome no. 1: BGL2 ≥ 45 mg/dL and outcome no. 2: BGL3 ≥ 45 mg/dL. Compared to i.v. glucose, the i.m. glucagon group had significantly more infants with BGL2 ≥ 45 mg/dL (40% vs. 76%, p = 0.028), and marginal significant difference regarding BGL3 ≥ 45 mg/dL (62% vs. 77%, p = 0.08). Univariate analysis showed that i.m. glucagon, male gender, vacuum extraction, cesarean delivery and one or more NH risk factors were significantly associated with outcome measure no. 1. I.m. glucagon, small for gestational age status, cesarean delivery, BGL1 and NH risk factors were associated with outcome measure no. 2. Multi-variate analysis showed that i.m. glucagon was significantly and independently associated with BGL2 ≥ 45 mg/dL. I.m. glucagon is worth consideration as a treatment option for NH.

Published: June 2019

AbstractBackgroundMalignant peritoneal mesothelioma (MPM) is a rare tumoral disease characterized by the diffuse involvement of the peritoneal serosa. The standard frontline treatment of MPM is cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) unless the peritoneal disease is considered unresectable. For unresectable patients the standard frontline treatment is a combination of cisplatin and pemetrexed but the prognosis remains ominous with only 13 months of overall survival (OS).MethodsThe proposed study is a multicenter randomized non-comparative study evaluating the association of Pressurized Intra-Peritoneal Aerosol Chemotherapy (PIPAC) and systemic chemotherapy vs. systemic chemotherapy alone as first-line treatment of MPM. Patients will be randomized with a 2:1 ratio using a minimization technique. Sixty-six patients have to be enrolled. Stratification will be performed according to histology (epithelioid vs. sarcomatoid and biphasic), presence of extraperitoneal disease and center. Primary objective is OS and secondary objectives include progression-free survival (PFS), safety, compliance, feasibility, conversion to resectability, histological response to treatment and quality of life.ConclusionsWe expect to show that intensification of the first line treatment with PIPAC for initially unresectable MPM patients increases OS.Trial registrationProspective study.

Effect of Indium Doping on Optical Parameter Properties of Sol–Gel-Derived ZnO Thin Films
Authors: Kocyigit Adem , Erdal Mehmet Okan , Yıldırım Murat 
Published: June 2019

Abstract
Zinc oxide (ZnO) has gained great interest for two decades, and its structural, optical, and electrical properties have been investigated by scientists for technological applications. The optical properties of ZnO provide an opportunity for its application in solar cells, lasers, and light-emitting diodes. We prepared ZnO thin films with various In doping levels by using a spin coating technique, and characterised their morphological and detailed optical properties for optical applications. According to the morphological properties obtained by atomic force microscopy, the film surfaces are homogeneous and the In doping level affects the surface morphology of the films. The optical properties of the films were investigated using an ultraviolet–visible spectrometer, and some optical parameters such as band gap, refractive index, extinction coefficient, single oscillator parameters, real and imaginary functions of the dielectric coefficient, and optical conductivity were calculated and discussed in detail. The various In doping levels affected the optical properties, and the In-doped ZnO thin films can find applications in industry.

Published: June 2019

Abstract
In the search for bioactive secondary metabolites from terrestrial fungi, four compounds, namely, 3-methyl-3H-quinazolin-4-one (1), aurantiomide C (2), 3-O-methylviridicatin (3), and dehydrocyclopeptine (4), were isolated from Penicillium sp. 8PKH, fungal strain, isolated from deteriorated rice straws. The structures of the isolated compounds were identified by extensive NMR and mass analyses and comparison with literature data. This is the first report of the structure of 3-methyl-3H-quinazolin-4-one (1) with full NMR spectral data having been previously identified by GC-MS from Piper beetle. Analysis of the non-polar fractions of the strain extract by GC-MS revealed the presence of additional eight compounds: methyl-hexadecanoate, methyl linoleate, methyl-9 (Z)-octadecenoate, methyl-octadecanoate, cis-9-oxabicyclo (6.1.0) nonane, 9,12-octadecadienal (9E,12E), ethyl-(E)-9-octadecenoate, and 3-buten-2-ol. The isolated compounds were evaluated for their antimicrobial and cytotoxic activities and exhibited little or no inhibitory activities against the test strains. The taxonomical characterisation and fermentation of the fungal strain were reported as well.
Does the use of a colour coded inpatient capillary blood glucose monitoring chart influence outcomes?
Authors: Sharma Dhiraj , Gerlach Matthew , Sharma Vivek , Dhatariya Ketan 
Published: June 2019

Background: Dysglycaemia in hospital inpatients is associated with harm. However, bedside capillary glucose monitoring often occurs with inadequate frequency, with inappropriate action taken when dysglycaemia occurs.Aims: To assess whether the introduction of a colour coded blood glucose monitoring chart had an impact on glycaemic control, documentation of action taken, length of stay and mortality in an unselected cohort of hospital inpatients.Methods: A cross-sectional study before (2014) and after (2017) the introduction of the new chart was undertaken. Data were collected for the 24 hours prior to inclusion in the study.Results: Data from 56 individuals were collected in 2014 and from 161 in 2017. 57% and 22% experienced dysglycaemia in 2014 and 2017, respectively. Action was taken in 24.2% of cases in 2014 and in 56.8% in 2017. Median length of stay was 16.1 days (IQR 8.4–39.4) in 2014 and 13.1 days (5.7–25.3) in 2017. For those who experienced dysglycaemia and in whom action was not recorded, mortality was 30% and 20% in 2014 and 2017 compared with 6% and 15%, respectively, for those who had no dysglycaemia.Conclusions: The introduction of a colour coded blood glucose monitoring chart led to more action being recorded when dysglycaemia occurred and reduced length of hospital stay and mortality.
Matrix Linear Models for High-Throughput Chemical Genetic Screens
Authors: Liang Jane W , Nichols Robert J , Sen Śaunak 
Published: June 2019

AbstractWe develop a flexible and computationally efficient approach for analyzing high-throughput chemical genetic screens. In such screens, a library of genetic mutants is phenotyped in a large number of stresses. Typically, interactions between genes and stresses are detected by grouping the mutants and stresses into categories, and performing modified t-tests for each combination. This approach does not have a natural extension if mutants or stresses have quantitative or nonoverlapping annotations (e.g., if conditions have doses or a mutant falls into more than one category simultaneously). We develop a matrix linear model (MLM) framework that allows us to model relationships between mutants and conditions in a simple, yet flexible, multivariate framework. It encodes both categorical and continuous relationships to enhance detection of associations. We develop a fast estimation algorithm that takes advantage of the structure of MLMs. We evaluate our method’s performance in simulations and in an Escherichia coli chemical genetic screen, comparing it with an existing univariate approach based on modified t-tests. We show that MLMs perform slightly better than the univariate approach when mutants and conditions are classified in nonoverlapping categories, and substantially better when conditions can be ordered in dosage categories. Therefore, it is an attractive alternative to current methods, and provides a computationally scalable framework for larger and complex chemical genetic screens. A Julia language implementation of MLMs and the code used for this paper are available at https://github.com/janewliang/GeneticScreen.jl and https://bitbucket.org/jwliang/mlm_gs_supplement, respectively.
“Go ask Alice, when she’s 10-feet tall”: Psychosocial correlates to lifetime LSD use among a national sample of US adults
Authors: Yockey Robert Andrew , King Keith A. , Vidourek Rebecca A. 
Published: June 2019

Introduction
Once thought a rarely used drug, LSD use is steadily increasing among US adults. A greater understanding of social factors and psychological determinants leading to lifetime LSD use can assist health educators and professionals in treating this growing problem. This study analyzed psychosocial factors related to LSD use among a national sample of adults.

Methods
A secondary data analysis of the 2017 National Survey on Drug Use and Health was performed.

Results
Results from the final multivariate logistic regression revealed that those who were male, African American or Hispanic, used alcohol, ecstasy, marijuana, inhalants, cocaine, and cigarettes before the age of 21 years, thought about suicide, got a kick out of doing things risky, and tested oneself to do risky things were more likely to use LSD.

Conclusions
This suggests that psychodynamic processes, for example, possible activation of emotional conflicts – can take place spontaneously – during ayahuasca intake in this particular setting. Some participants attributed symbolic meaning to the visionary content, which was more likely to take place in psychotherapeutically motivated clients. The specific setting influence as well as corresponding expectations of the participants in native wisdom could have considerable influence on experiences and interpretations, such as communication with entities as well as receiving personal teachings.
WASIAT WAJIBAH UNTUK ANAK ANGKAT DALAM KHI DAN FIKIH
Authors: Misno Misno 
Published: June 2019

AbstrakIslam sebagai aturan hidup yang paripurna memiliki seperangkat aturan yang komprehensif mencakup berbagai sendi kehidupan manusia. Salah satu aturan dalam Islam adalah mengenai pengambilan seorang anak sebagai anak angkat. Islam mengatur bagaimana hubungan antara anak angkat dan orang tua angkatnya. Anak angkat tidak boleh dinasabkan kepada orang tua angkatnya dan di antara mereka tidak saling mewa­risi. Permasalahan akan muncul ketika seorang mengambil seorang anak sebagai anak angkat, namun tiba-tiba orang tua tersebut mening­gal dunia. Sementara anak angkatnya masih kecil dan belum mampu untuk mencari nafkah sendiri. Apakah anak tersebut tetap tidak bisa mendapatkan bagian harta warisan orang tua angkatnya? Bagaimana persepsi Imam Madzhab mengenai hal ini?Kesimpulan dalam penelitian adalah bahwa Imam Madzhab membahas mengenai wasiat dalam mak­na umum, mereka belum membahas secara spesifik mengenai Wasiat wajibah. Namun statement mereka mengenai wasiat dapat menjadi dasar hukum bagi kebolehan Wasiat wajibah bagi anak angkat. Alasan­nya adalah adanya kemashalahatan bagi anak angkat karena tidak ada yang menanggung beban hidupnya. Jika dia tidak bisa mendapatkan bagian dari harta yang ditinggalkan orang tua angkatnya, tentu akan memunculkan kemudharatan baginya.Kata Kunci: Wasiat Wajibah, KHI, Anak Angkat

An Assemblage from a Medieval Burial at Lake Parisento, Gydan Peninsula, the Arctic Zone of Western Siberia

Published: June 2019

The article introduces an assemblage from a child burial discovered in the central Gydan Peninsula, Tazovsky District, YamalNenets Autonomous Okrug. Little is known about the archaeological past of Arctic Western Siberia, and these fi nds are relevant to the study of the medieval period of that area. Medieval burials were studied only in the adjacent peninsula of Yamal. The discovery of the burial is described in detail. It was exposed owing to soil eolation. Artifacts were redeposited, and virtually the entire skeleton was missing. In a lump of soil stuck to the metal bowl, a few bone fragments and hair was found. Their analysis suggests that the individual was an infant aged 1–3. The assemblage includes an imported bronze bowl, a bronze haft of a knife, a scabbard, and a silver earring. The bowl, made of tin bronze, was apparently manufactured in eastern Iran or Central Asia in the 10th or 11th century. The haft and the scabbard, judging by the type and technology, belonged to a category of artifacts that were common in the Lower Ob basin, the southern Yamal, and the Ural in the late fi rst and early second millennia. On the basis of the results of X-ray fl uorescence analysis, we assess the chemical composition of the metal of which all those artifacts are made. The decorated fragment of a clay vessel is attributed to the Tiutey-Sale variant (800–1300 AD) of the Lower Ob culture. The totality of indicators suggests a date between 900 and 1100 AD. We conclude that the tundra areas of the Yamal and Gydan peninsulas were colonized by migrants from the northern taiga zone of Western Siberia.
On the Methodology of Studying Palimpsests in Rock Art: The Case of the Shalabolino Rock Art Site, Krasnoyarsk Territory
Authors: Zotkina L. V. 
Published: June 2019

This paper addresses the main problems in assessing the stratigraphy of superimpositions in rock art. When a petroglyph is overlain by one or several others, this may provide important information not only about single images but also about entire stylistic traditions. Existing methods used for evaluating the relative chronology of the parts of petroglyphic palimpsests are discussed, and a new approach is proposed, combining high-resolution three-dimensional visualization at the macro-level with traceological analysis. We focus on the characteristics of the pecked surface in the area outside the palimpsest and that in the overlap zone. The comparison of these parts makes it possible to reveal the traceologically informative features in the palimpsest areas, indicating the sequence of superimposed petroglyphs. This approach is instantiated by the analysis of one of the palimpsests in the Shalabolino rock gallery, the Krasnoyarsk Territory. Images representing various stylistic traditions are found in complicated stratigraphic relations. The sequence of three main fi gures (bear, bull, and elk) in this multilayered composition has been reconstructed. The results of the analysis cannot be used as an argument for attributing these petroglyphs to vastly different chronological periods. Rather, they provide new information relevant to the debate around the age of the Angara and Minusinsk petroglyphic styles in the Minusinsk Basin.
