Influence of Process Models on Requirement Volatility, and Strategies for its Management – An Empirical Investigation
Authors: Thakurta Rahul
Published: November 2018

The current research aims to investigate the preparedness among organizations in managing requirement volatility, and how it is influenced by process factors characterizing a software project. A combination of interviews and survey organized in two phases has been used to assess the level of awareness related to requirement volatility, and the current level of organizational competencies in dealing with the problem. Frameworks regarded suitable for handling volatility has been presented. Factors governing process model selection and usage and their applicability under requirement volatility have also been explored.

Concerns were raised over the high percentage of projects found affected because of requirement volatility. Two widely used approaches for managing projects under volatility were found to be involving the business side and resorting to iterative project development. Difference in usage of the approaches based on process models could be observed. Influence of business/customers, project complexity and managerial preferences emerged as the top three factors guiding process model selection. The variation of these factors under requirement volatility has been pointed out. The results also highlight incongruence between perception and practice related to process model usage in projects endangered because of requirement volatility.
Semantics for Interactive Sequential Systems and Non-Interference Properties
Authors: Lee Matias , D’Argenio Pedro R.
Published: November 2018

An interactive system is a system that allows communication with the users. This communi- cation is modeled through input and output actions. Input actions are controllable by a user of the system, while output actions are controllable by the system. Standard semantics for sequen- tial system [1, 2] are not suitable in this context because they do not distinguish between the different kinds of actions. Applying a similar approach to the one used in [2] we define seman- tics for interactive systems. In this setting, a particular semantic is associated with a notion of observability. These notions of observability are used as parameters of a general definition of non-interference. We show that some previous versions of the non-interference property based on traces semantic, weak bisimulation and refinement, are actually instances of the observability- based non-interference property presented here. Moreover, this allows us to show some results in a general way and to provide a better understanding of the security properties.

Published: November 2018

An indispensable condition for the individualization of a person's health-saving support is the provision of constant monitoring of the functional state of the body through the application of standard methods of instrumental rapid testing. As a result of a complex of experimental studies involving 126 people, using indicators of electroencephalography, cardiointervalography and general nonspecific reactivity of the organism, a number of interrelationships of functional, psychophysiological and psychological characteristics that determine a person's inclination to develop psychoemotional tension are revealed. The possibility of using the level of general nonspecific reactivity as a criterion for assessing the individual risk of forming a psychoemotional disadaptation in a person is substantiated. At the same time, as a marker phenotypic sign determining the risk of development of psychoemotional disadaptation, a high level of general nonspecific reactivity of the organism was isolated.

Published: November 2018

This article describes the influence of vaginal operations on the elimination of PG on the sexual function of patients. In women with genital prolapse, low rates of the index of female sexual function were noted. In the long-term postoperative period, there was a significant improvement in all indicators of the female sexual function index (FSFI), except for orgasm and dyspareunia (p ≥ 0,05), in comparison with similar indicators before the operation. Vaginal operations with prolapse of genitals using polypropylene nets and without them improve sexual function. The overall score of the index of sexual function is significantly increased in patients who underwent correction of genital prolapse with an ultralight and light implant from 15,8 ± 5,3 to 25,2 ± 4,2 and from 15,5 ± 5 to 21,4 ± 6,0, respectively in patients with the use of their own tissues - from 16,1 ± 6,7 to 21,7 ± 8,5.

Study of the involution processes of the postpartum uterus and the development of it's regulatory tools is of great importance for the clinic medicine. The purpose of our work was to study the effect of the drug «Dalargin» on the condition of the uterus in rats on the 7th day after childbirth. During the study 2 groups of animals were identified: group № 1 (n = 15) - control, intact female rats after the parturition; group № 2 (n = 15) - experimental, female rats received the drug «Dalargin» 1.1 mg / kg for 3 days after the parturition. According to the histological researches it can be seen that epithelization of the uterine horn in rats of both groups by the 7 days after the parturition is at the stage of completion. Female rats from group № 2 (received «Dalargin») showed that the thickness of the uterine horn wall was 9 % higher, the thickness of the myometrium was 12 % higher, the thickness of the single-layer prismatic epithelium layer was 31 % higher than in the control. A feature of rats received «Dalargin» is the restoration of a layer of mucus on the surface of the endometrium by 7 days after the parturition. Thus, the use of the drug «Dalargin» enhances the recovery of the endometrium of the uterus after the parturition and slows the turnover in the myometrium.

Published: November 2018

People localization is a key building block in many applications. In this paper, we propose a deep learning based approach that significantly improves the localization accuracy and reduces the runtime of Wi-Fi based localization systems. Three variants of the deep learning approach are proposed, a sub-task architecture, an end-to-end architecture, and an architecture that incorporates prior knowledge. The performance of the three architectures under different conditions is evaluated and the significant improvement of the three architectures over existing approaches is demonstrated.
Avoiding AGI Races Through Self-Regulation
Authors: Worley III G Gordon
Published: November 2018

The first group to build artificial general intelligence or AGI stands to gain a significant strategic and market advantage over competitors, so companies, universities, militaries, and other actors have strong incentives to race to build AGI first. An AGI race would be dangerous, though, because it would prioritize capabilities over safety and increase the risk of existential catastrophe. A self-regulatory organization (SRO) for AGI may be able to change incentives to favor safety over capabilities and encourage cooperation rather than racing.

Authors: Mahammedi Nassim Ahmed , Ferhat Marhoun
Published: November 2018

By means of density functional theory (DFT) calculations, we have investigated the effect of hydrostatic pressure on the structural, electronic and elastic properties of the barium-doped silicon clathrate Ba8Si46 in the type-VIII structure (α phase). Physical properties are calculated under different conditions of pressure (0 GPa to 45 GPa) using the GGA-PBE functional, those calculations have been performed using the Cambridge serial total energy package CASTEP code within the Materials Studio package. Electronic properties have shown that the type-VIII Ba8Si46 has metal-like properties with a fundamental bandgap of 1 eV. Under pressure the fundamental bandgap increases slightly and the positions of the valence band maximum VBM and the conduction band minimum CBM remain unchanged. We found that the compound is mechanically stable under the pressure range, but this needs to be confirmed experimentally through synthesis, a comparison with the type-I and the guest-free counterparts has exhibited promising features for the type-VIII Ba8Si46.

Published: November 2018

The aim of this study was to gather preliminary data about the potential inhibitory effects and contributions of live foods used from 3 to 32 days after hatching (DAH) in routine feeding protocols on protease activities of meagre, Argyrosomus regius (Asso 1801) larvae, using in vitro techniques. Enriched rotifer, Artemia nauplii and Artemia metanauplii were tested in the present study. The highest values of protease activities of meagre larvae at 7 DAH in 2013 and 2014 years were established. The lowest values at 15 DAH in 2013 and at 20 DAH in 2014 were observed. Protease activities of enriched rotifer, Artemia nauplii, and Artemia metanauplii were 21.76±0.31, 36.00±1.48–29.33±0.93, and 416.44±19.7–403.53±11.85 U/mg protein, respectively (p< 0.05). The highest inhibitions of live foods were observed at 7 DAH. The positive contributions of live food Artemia metanauplii’s on protease activities of meagre larvae were significant (p< 0.05). The inhibitory effects and positive contributions of live foods on survival and growth rates of meagre larvae, should be taken into account in meagre and other marine fish larvae’s future studies. Cysteine protease activities of Artemia sp. should be investigated to provide the higher growth and survival ratio from the feeding protocols used in marine fish larvae.

Authors: Lee Marely , Xing Shuli
Published: November 2018

To improve the tangerine crop yield, the work of recognizing and then disposing of specific pests is becoming increasingly important. The task of recognition is based on the features extracted from the images that have been collected from websites and outdoors. Traditional recognition and deep learning methods, such as KNN (k-nearest neighbors) and AlexNet, are not preferred by knowledgeable researchers, who have proven them inaccurate. In this paper, we exploit four kinds of structures of advanced deep learning to classify 10 citrus pests. The experimental results show that Inception-ResNet-V3 obtains the minimum classification error.

Hyperkalemia burden in non-dialysis CKD under nephrology care is undefined. We prospectively followed 2443 patients with two visits (referral and control with 12-month interval) in 46 nephrology clinics. Patients were stratified in four categories of hyperkalemia (sK≥5.0 mEq/L) by sK at visit 1 and 2: Absent (no-no), Resolving (yes-no), New Onset (no-yes), Persistent (yes-yes). We assessed competing risks of ESKD and death after visit 2. Age was 65±15 y, eGFR 35±17 mL/min/1.73 m2, proteinuria 0.40 (0.14-1.21) g/24h. In the two visits sK was 4.8±0.6 and levels ≥6 mEq/L were observed in  4%. Hyperkalemia was absent in 46%, resolving 17%, new onset 15% and persistent 22%. Renin-angiotensin-system inhibitors (RASI) were prescribed in 79% patients. During 3.6-year follow-up, 567 patients reached ESKD and 349 died. Multivariable competing risk analysis [sub-hazard ratio-sHR, 95%Confidence Interval-CI] evidenced that new onset [sHR 1.34, 95%CI 1.05-1.72] and persistent [sHR 1.27, 95%CI 1.02-1.58] hyperkalemia predicted higher ESKD risk versus absent, independently from main determinants of outcome including eGFR change. Conversely, no effect on mortality was observed. Results were confirmed by testing sK as continuous variable. Therefore, in CKD under nephrology care, mild-to-moderate hyperkalemia status is common (37%) and predicts per se higher ESKD risk but not mortality.

Authors: Shintani Hideya , Shintani Tomoya , Ashida Hisashi , Sato Masashi
Published: November 2018

Calorie restriction (CR) has been shown to prolong the lifespan of humans, but enforcing long-term CR is difficult. Therefore, a compound that reproduces the effect of CR without CR is needed. In this review, we summarize the current knowledge on compounds with CR mimetic (CRM) effects. More than 10 compounds have been listed as CRMs, some of which are conventionally categorized as upstream-type CRMs showing glycolytic inhibition while the others are categorized as downstream-type CRMs that regulate or genetically modulate intracellular signaling proteins. Among these, we focus on upstream-type CRMs and propose their classification as compounds with energy metabolism inhibition effects, particularly glucose metabolism modulation effects. The upstream-type CRMs reviewed include chitosan, acarbose, sodium-glucose cotransporter 2 inhibitors, and hexose analogs such as 2-deoxy-D-glucose, D-glucosamine, and D-allulose, which show anti-aging and longevity effects. Finally, we discuss the molecular definition of upstream-type CRMs.

Published: November 2018

Structural vibration induced by dynamic load or natural vibration is a nonnegligible factor in failure analysis. Based on vibrating boundary condition, impact resistance of shape memory alloy reinforced composites is investigated. In this investigation, modified Hashin’s failure criterion, Brinson’s model and visco-hyperelastic model are implemented into the numerical model to charactering the mechanical behavior of glass fiber/epoxy resin laminates, SMAs and interphase, respectively. First, fixed boundary condition is maintained in simulation to verify the accuracy of material parameters and procedures by comparing with experimental data. Then, a series of vibrating boundaries with different frequencies and amplitudes are applied during the simulation process to reveals the effect on impact resistances. The statistics of absorbed energy and contact force indicate that impact resistance of the composite under high frequency and large amplitude is lower than that under low frequency and small amplitude, and summarized by a mathematical expression.

The objective of this study was to perform a systematic review and meta-analysis of the articles that addressed the effect BA or carnosine supplementation on Physical exercise (PE)-induced oxidative stress (OS). We searched throughout PubMed, CAPES Periodic and SPORTDiscus human model peer review, randomized control studies with chronic BA or carnosine supplementation on PE-induced OS. We search papers published before May 2018. A total of 128 citations were found. Only four articles met criteria for inclusion. All four studies used healthy young (21y) sedentary, recreationally active or athletic participants. After a chorionic BA (~30 days) or carnosine (14 days) supplementation, the studies evaluated PE-induced OS both immediately and several hours after exercise (0.5 to 48 h). In response to PE-induced OS, when compared to placebo, BA/carnosine supplementation increased total antioxidant capacity [TAC; Effect Size (ES) = 0.35, 95% Confidence Interval (CI) 0.06 to 0.65, p = 0.02] and glutathione (GSH; ES = 0.75, 95% CI 0.32 to 1.19, p = 0.0007) concentrations while decreased pro-oxidant markers (ES = −1.19, 95% CI −1.48 to -0.80, p < 0.01) and superoxide dismutase (SOD) activity (ES = −0.58, 95% CI −1.10 to −0.06, p = 0.03). BA or carnosine supplementation did not prevent the increase in peroxidation markers (ES: −0.20, 95% CI −0.59 to 0.20, p = 0.33). In humans, following PE-induced OS, initial treatment trials of BA or carnosine supplementation seemed to increase TAC and GSH concentrations, while decreasing SOD activity. Also, albeit mitigating the acute increase in pro-oxidants, treatment did not decrease measured values of peroxidation markers.

Published: November 2018

In this study, the changes in mass, compressive strength and length were analyzed to investigate sulfate resistance according to ground granulated blast furnace slag (GGBFS) blending ratio and type of sulfate solution. All alkali activated mortars showed excellent sulfate resistance when immersed in sodium sulfate (Na2SO4) solution. However, when immersed in magnesium sulfate (MgSO4) solution, different sulfate resistance results were obtained depending on the presence of GGBFS. Alkali activated GGBFS blended mortars showed a tendency to increase mass, increase length and decrease compressive strength when immersed in magnesium sulfate solution, but the alkali activated FA mortars did not show any significant difference depending on the types of sulfate solution. The deterioration of alkali activated GGBFS blended mortars in the immersion of magnesium sulfate solution was confirmed by the decomposition of C-S-H which is the reaction product by magnesium ion and the formation of gypsum (CaSO4·2H2O) and brucite (Mg(OH)2).
Instantaneous Quantum Description of Photonic Wavefronts and Applications
Authors: Vatarescu Andre
Published: November 2018

By imposing the condition of non-vanishing expectation values for the amplitude and phase of field operators, pure quantum states are identified composed of two consecutive number states. These pure states also deliver noise-free radiation modes restricting the “half-photon noise” to the expectation value of the lowest level of dynamic and coherent number states. As a result, instantaneous phase-sensitive amplification of photons is easily controlled and direct evaluation of time or distance - varying wavefront distributions of photons and phases can be carried out for sub-Poissonian distributions of photons without the need for quasi-probabilities.
Sustainability of Vocabulary Teaching after Explicit Instruction in Kindergarten Children
Authors: Dikici İsmail Zeki , Kunt Naciye
Published: November 2018

This study investigates five-year-old learners’ vocabulary retention through case studies, on a one week, one month, three months, and five months basis. It concerns the vocabulary learning of kindergarten children learning English as a second language (L2). This study attempts to seek answers to the questions of to what extent the presentation of the three different sets of words more effective than the other two is, both on recall and recognition and whether the recall and recognition levels showed differences in the three sets of words in course of time. In the literature, some studies have favoured semantic mapping in which new words are presented and organized in terms of associated lexical meanings. Some other studies have disfavoured semantic mapping. This study has administered three different sets of vocabulary: semantically related, cognates and semantically unrelated words. This study indicated that all participants were more successful with semantically related words on word recall and with cognates on word recognition. The results of this study do not support those which claim that making semantic associations may cause interference and hinder vocabulary learning. This study further suggests that semantically related words should be taught thematically to facilitate vocabulary teaching, particularly on word recall.

Low concentrations (5 ppm, 10 ppm and 25ppm) of the marker analytes were measured, obtaining high sensitivities, good reproducibility, short time response and fast signal recovery.
From LiDAR waveforms to Hyper Point Clouds: a novel data product to characterize vegetation structure
Authors: Zhou Tan , Popescu Sorin , Malambo Lonesome , Zhao Kaiguang , Krause Keith
Published: November 2018

Full waveform (FW) LiDAR holds great potential for retrieving vegetation structure parameters at a high level of detail, but this prospect is constrained by practical factors such as lack of available handy processing tools and technical intricacy of waveform processing. This study introduces a new product, named the Hyper Point Cloud (HPC) derived from FW LiDAR data, and explore its potential applications such as tree crown delineation using the HPC-based intensity and percentile height (PH) surfaces, which show a promising solution to the constraints of using FW LiDAR data. Results of the HPC present a new direction to handle FW LiDAR data and offer prospects for studying the mid-story and understory of vegetation with high point density (~ 182 points/m2). The intensity-derived digital surface model (DSM) generated from the HPC shows that the ground region has larger maximum intensity (MAXI) and mean intensity (MI) than the vegetation region while having smaller total intensity (TI) and number of intensities (NI) at the given grid cell. Our analysis of intensity distribution contours at individual tree level exhibit similar patterns, indicating that the MAXI and MI are decreasing from the tree crown center to tree boundary while a rising trend is observed for TI and NI. These intensity variable contours provide a theoretical justification for using HPC-based intensity surfaces to segment tree crowns and exploit their potential for extracting tree attributes. The HPC-based intensity surfaces and the HPC-based PH Canopy Height Models (CHM) demonstrate promising tree segmentation results comparable to the LiDAR derived CHM for estimating tree attributes such as tree locations, crown widths and tree heights. We envision that products such as the HPC and the HPC-based intensity and height surfaces introduced in this study can open new perspectives to use FW LiDAR data and alleviate the technical barrier of exploring FW LiDAR data for detailed vegetation structure characterization.

Published: November 2018

Using nanoindentation under various strain rates, the mechanical properties of a selective laser melted (SLM) SKD61 at the 800 mm/s scan speed was investigated and compared to SLM H13. No obvious pile-up due to the ratio of the residual depth (hf) and the maximum depth (hmax) being lower than 0.7 and no cracking were observed on any of the indenter surfaces. The nanoindentation strain-rate sensitivity (m) of SLM SKD61 was found to be 0.034, with hardness increasing from 8.65 GPa to 9.93 GPa as the strain rate increased between 0.002 s−1 and 0.1 s−1. At the same scan speed, the m value of SLM H13 (m = 0.028) was lower than that of SLM SKD61, indicating that the mechanical behavior of SLM SKD61 was more critically affected by the strain rate compared to SLM H13. SLM processing for SKD61therefore shows higher potential for advanced tool design than for H13.
The Effects of Quantitative Easing Announcements on the Mortgage Market: An Event Study Approach
Authors: Wang Gang
Published: November 2018

This paper uses event study analysis to estimate the impact of the Fed’s Quantitative Easing (QE) announcements on the mortgage market during zero lower bound period. A total of 35 QE announcements are identified and their effects are evaluated. The best-fitting IGARCH model with skewed t distribution is used to measure the QE announcement effects on daily changes of the 30-year mortgage rate, the 30-year Treasury rate and the spread between them. Announcements suggesting the start of a new round of QE reduced the mortgage rate tremendously, while the effects of further news diminished. Announcements of an increase in mortgage-backed security purchases decreased the mortgage rate more than the Treasury rate and reduced the credit risk of holding mortgage securities over Treasury securities. The long run effects of QE announcements on the mortgage rate were less than short run effects but persistent. We also find that the previous literature overestimate QE effects on interest rates in general.

Published: November 2018

Augment reality (AR) is crucial for immersive human-computer interaction (HCI) and vision of artificial intelligence (AI). Labeled data drove object recognition in AR. However, manual annotating data is expensive and labor-intensive, and furthermore, scanty labeled data limits the application of AR. Aiming at solving the problem of insufficient training data in AR object recognition, an automated vision data synthesis method called BAGAN is proposed in this paper based on the 3D modeling and GAN algorithm. Our approach has been validated to have better performance than other methods through image recognition task on natural image database ObjectNet3D. This study can shorten the algorithm development time of AR and expand the application scope of AR, which is of great significance to immersive interactive systems.

Published: November 2018

The issue of the use of code switching as instructional languages in the class has already become a worldwide concern. Some experts may say that it is beneficial while others believe that it is not since it may become the interference for the learning. Through this paper, the researchers want to investigate the use of code switching in General English Classes for non-English Department of Sanata Dharma University. Employing a quantitative approach, specifically observation method by recording the class activity, this study tries to find out the types and analyse code switching employed by lecturers in the classes. The data analyses revealed that tag switching, intra-sentential and inter-sentential code switching are employed by lecturers and the code switching itself functions as the topic switch, repetitive and affective function. The inter-sentential code switching was mostly used by the lecturer and it mostly served as a repetitive function to explain and show their affection to students

Authors: O. Al-Smadi Mohammad
Published: November 2018

This study aims to examine the relationship between financial inclusion and financial stability in Jordan by using Fully Modified Least Squares (FMOLS) technique. The analysis is based on time series from 2006 to 2017. Jordanian financial inclusion index is developed to assess the level of financial inclusion, whereas financial stability was measured by Jordanian financial stability index proposed by Central Bank of Jordan. The results show a weak significant and positive impact of financial inclusion on the financial stability in Jordan. Additionally, five control variables are used in the study. The results show a negative impact of domestic credit to private sector, income inequality, financial integration, and global financial crisis on financial stability. In contrast, real GDP per capita has a significant and positive impact. It is expected that the findings of the study can be used by policy makers and supervising authorities to realize the objectives of the national strategy of financial inclusion in Jordan.

A study that enrolled 30 patients with advanced colorectal cancer, who had not previously received any specific drug treatment, was conducted to develop and study a three-component regimen with oral fluoropyrimidine tegafur (Ftorafur) in outpatient practice. The study evaluated the time to disease progression (TDP), the overall survival (OS) of patients, who received irinotecan + oxaliplatin + Ftorafur in the first-line therapy, as well as the effectiveness and safety of this regimen. 6 patients received a 3-week chemotherapy cycle (Fig. 1), 24 patients – a 2-week chemotherapy cycle (Fig. 2). The preliminary results of the study have been obtained. The median OS was not reached, the median TDP was 8.5 months. In Group I, there was partial regression of metastasis in 3/6 patients, and prolonged disease stabilization (≥ 6 months) in 3 patients. The therapeutic effect (partial remission + long-term stabilization ≥ 6 months) was observed in all patients. The duration of TDP was from 6 to 15 months. In group II, the effect was evaluated in 24 patients, who received at least 2 chemotherapy cycles. 14/24 patients had a partial response (PR), of which 4 (16.6%) patients were radically operated, 6 patients elicited disease stabilization. Thus, control over the disease was achieved in 83.33% of patients in Group II. Oxaliplatin combined with irinotecan and fluorafur was effective, had an acceptable toxicity profile, and therefore, can be used in debilitated patients with disseminated disease.

The article considers the place of nab-paclitaxel in the treatment of metastatic breast cancer. A number of studies have shown high efficacy and acceptable toxicity in comparison with traditional taxanes. The low frequency of hypersensitivity reactions allows the use of nab-paclitaxel in patients who had reactions with the introduction of traditional taxanes and in the presence of contraindications to corticosteroids premedication. The absence of cross-resistance makes possible to prescribe nabpaclitaxel in patients who had progression on treatment with paclitaxel and docetaxel. The cases of effective use of the drug from our own practice are presented.

The article presents the results of a study of the influence of the sylvinite speleoclimatic chamber and neurofeedback-therapy on the student’s adaptation process. With the help of automated methods of psychophysiological features, the authors studied parameters of heart rate variability, indices of personal and situational anxiety and the general health – activity – mood test in 29 students of the university during the period of training before and after the health measures. It has been established that ten sessions of speleoclimatotherapy did not affect the specificity of neurodynamic parameters, but led to a change in the psychological state of students and the degree of tension of regulatory systems: the number of people with high situational anxiety decreased, a positive trend was observed in terms of well-being, activity, mood; the values of the integral index of the stress index decreased. At the impact of ten sessions of the nerofeedback-training there are significant changes in the mechanisms of regulation of the heart rhythm: the degree of tension of the regulatory systems decreases and the activity of sympathetic and parasympathetic influences on the regulation of the heart rhythm; vegetative regulation has shifted either towards the equilibrium effect of the autonomic nervous system, or in the direction of intensifying the activity of parasympathetic influences.
THE EXPERIENCE OF BUILDING INDUSTRY ZONING IN SIBERIA
Authors: Рогов Петр , Rogov Petr
Published: November 2018

The building industry of Siberia is the locomotive sector of the economy that provides the basic conditions for the development of the region. The construction employs a significant number of the population of the region, including in the production of sociallyoriented construction products. However, there are regional differences in the structure of the GRP and volume of buildings, including housing. Construction is an organizing industry that develops the economy of the region, its economic attractiveness and improves the living conditions of the population. However, there is a concentration of construction activity closer to economic centers, while peripheral areas are less active. To identify problems of nonuniformity in construction activity the authors have developed a ranking system. It uses key statistical indicators that allow one to carry out zoning and subsequent monitoring of the differentiation of the construction industry in Siberian regions, as well as to design policies aimed at improving the investment climate for the construction industry both on the regional and lower levels.
