Modeling the Performance Indicators of Financial Assets with Neutrosophic Fuzzy Numbers
Authors: Bolos Marcel-Ioan , Bradea Ioana-Alexandra , Delcea Camelia
Published: August 2019

This research sets the basis for modeling the performance indicators of financial assets using triangular neutrosophic fuzzy numbers. This type of number allows for the modeling of financial assets performance indicators by taking into consideration all the possible scenarios of their achievement. The key performance indicators (KPIs) modeled with the help of triangular fuzzy neutrosophic numbers are the return on financial assets, the financial assets risk, and the covariance between financial assets. Thus far, the return on financial assets has been studied using statistical indicators, like the arithmetic and geometric mean, or using the financial risk indicators with the help of the squared deviations from the mean and covariance. These indicators are well known as the basis of portfolio theory. This paper opens the perspective of modeling these three mentioned statistical indicators using triangular neutrosophic fuzzy numbers due to the major advantages they have. The first advantage of the neutrosophic approach is that it includes three possible symmetric scenarios of the KPIs achievement, namely the scenario of certainty, the scenario of non-realization, and the scenario of indecision, in which it cannot be appreciated whether the performance indicators are or are not achieved. The second big advantage is its data series clustering, representing the financial performance indicators by which these scenarios can be delimitated by means of neutrosophic fuzzy numbers in very good, good or weak performance indicators. This clustering is realized by means of the linguistic criteria and measuring the belonging degree to a class of indicators using fuzzy membership functions. The third major advantage is the selection of risk mitigation analysis scenarios and the formation of financial assets’ optimal portfolios.

Dendritic cell [DC] vaccines can induce durable clinical responses, at least in a fraction of previously treated, late stage cancer patients. Several preclinical studies suggest that shielding programmed death-ligand 1 [PD-L1] on the DC surface may be an attractive strategy to extend such clinical benefits to a larger patient population. In this study, we evaluated the use of single domain antibody [sdAb] K2, a high affinity, antagonistic, PD-L1 specific sdAb, for its ability to enhance DC mediated T-cell activation and benchmarked it against the use of the monoclonal antibodies [mAbs], MIH1, 29E.2A3 and avelumab. Similar to mAbs, sdAb K2 enhanced antigen-specific T-cell receptor signaling in PD-1 positive (PD-1pos) reporter cells activated by DCs. We further showed that the activation and function of antigen-specific CD8 positive (CD8pos) T cells, activated by DCs, was enhanced by inclusion of sdAb K2, but not mAbs. The failure of mAbs to enhance T-cell activation might be explained by their low efficacy to bind PD-L1 on DCs when compared to binding of PD-L1 on non-immune cells, whereas sdAb K2 shows high binding to PD-L1 on immune as well as non-immune cells. These data provide a rationale for the inclusion of sdAb K2 in DC-based immunotherapy strategies.
Effect of the North Atlantic Thermohaline Circulation on Changes in Climatic Conditions and River Flow in Poland
Authors: Wrzesiński Dariusz , Marsz Andrzej A. , Styszyńska Anna , Sobkowiak Leszek
Published: August 2019

The purpose of this study is to find connections between the North Atlantic Thermohaline Circulation (NA THC), climate elements, such as cloud cover, precipitation, air temperature, sunshine duration, and relative humidity, and flow of rivers in Poland. The intensity of NA THC was characterized by the DG3L index, which was established to assess changes in the amount of heat transported by NA THC along with the transport of water to the Arctic. The paper explains and discusses the mechanism of impact of the NA THC changeability on the elements of the catchment water balance variability. The positive and negative phases of the DG3L index are strongly correlated with the heat anomalies in the upper layer of the North Atlantic waters. The obtained results show that changes of NA THC have significant impact on weather conditions and selected climate elements in Poland. Statistically significant positive correlations were found between the DG3L index and average annual air temperatures, particularly in April, July, and August, while negative between the DG3L index and the total cloud cover. Consequently, in the years with the positive values of the DG3L index, there are favorable conditions for the strong increase in evaporation and evapotranspiration from the ground surface. This has impact on flow of rivers in Poland, which shows considerable regional differences.
MRT-Lattice Boltzmann Model for Multilayer Shallow Water Flow
Authors: Tubbs Kevin R. , Tsai Frank T.-C.
Published: August 2019

The objectives of this study are to introduce a multiple-relaxation-time (MRT) lattice Boltzmann model (LBM) to simulate multilayer shallow water flows and to introduce graphics processing unit (GPU) computing to accelerate the lattice Boltzmann model. Using multiple relaxation times in the lattice Boltzmann model has an advantage of handling very low kinematic viscosity without causing a stability problem in the shallow water equations. This study develops a multilayer MRT-LBM to solve the multilayer Saint-Venant equations to obtain horizontal flow velocities in various depths. In the multilayer MRT-LBM, vertical kinematic viscosity forcing is the key term to couple adjacent layers. We implemented the multilayer MRT-LBM to a GPU-based high-performance computing (HPC) architecture. The multilayer MRT-LBM was verified by analytical solutions for cases of wind-driven, density-driven, and combined circulations with non-uniform bathymetry. The results show good speedup and scalability for large problems. Numerical solutions compared well to the analytical solutions. The multilayer MRT-LBM is promising for simulating lateral and vertical distributions of the horizontal velocities in shallow water flow.
The NPP-Based Composite Indicator for Assessing the Variations of Water Provision Services at the National Scale
Authors: Zheng Haibo , Zhang Liwei , Wang Pengtao , Li Yingjie
Published: August 2019

Water provision (WP) is an important service of the terrestrial ecosystem, which contributes to water availability for consumptive use and in situ water supply, sustains the production or flows of multiple ecosystem services (ES). Spatially explicit mapping of WP is critical for incorporating the ES concept into the decision-making processes of land-use and ecological conservation planning. Traditionally, regional complexes hydrological process models were simplified and used for mapping WP of the ecosystem at broad scales, but this approach is significantly limited by data accessibility and difficulty validating the results. To fill the gap, an NPP-based composite indicator model that simulates WP by multiplying NPP and its variations with the soil infiltration capacity factor, annual precipitation and the slope of the land surface is proposed in this paper. These parameters are chosen to map WP because they are closely related to hydrological processes. The model results were validated using observed runoff data of the eleven river basins in China. We then applied this approach to analyze the spatiotemporal changes of WP in China from 2000 to 2013. The results show that: (1) the average value of WP was lowest in the Northwest Arid Area ecoregions while the highest value of WP was in the South China ecoregion. (2) The linear trend of WP in the Loess Plateau and Hengduan Mountains ecoregions were increased while decreased in the other nine ecoregions. (3) The WP in the north of the Qinghai-Tibet Plateau presented a significant decrease trend mostly because the land cover change (e.g., grassland convert into dessert) and decreasing precipitation; the decreasing of the WP in Yunan-Guizhou Plateau are because the farmland convert into settlement land and the significant decrease of precipitation and significantly increase of temperature; the significant increase of the WP in Northeast China are because the increasing of forest and farmland, the grassland and wetland convert into farmland and forest, and the significant decrease of temperature and increase of precipitation; Although the increase of precipitation has played an important role in promoting WP, the significant increase of WP in the Loess Plateau was mainly due to the farmland convert into forest and grassland ecosystem types. The indicator explored by this research is benefiting for revealing the variations of WP under different land-use change and climate change, and informed the decision-making process of land-use policy or conservation planning at data-scarce regions or broaden spatial scales.
Investigation on presence of major gene for body weight, feed intake and feed efficiency using a segregation analyses in a mice population
Authors: Karacaören Burak , Moslem İssam
Published: August 2019

Recent developments in molecular genetics and statistics have
allowed the identification and use of major genes to explain the genetic
variation. In this context, segregation analysis is a fast, reliable and
inexpensive method that uses only phenotype and pedigree information. The aim
of this study was to examine whether body weight, feed intake, and feed
efficiency in a mouse population are directed by major gene in addition to
polygenic and major gene effects by segregation analysis. For this purpose,
previously collected dataset was used (n= 661). In this study, genetic
variance, error variance, major gene variance, additive and dominant gene
effects were estimated by segregation analyses. Dominant variance (1.04) was
found to be smaller than the additive genetic variance (7.32) for body weight.
Polygenic and major gene heritability predicted as 0.29 (± 0.63) and 0.81 (±
0.98) for body weight, 0.35 (± 0.63) and 0.96 (± 0.98) for feed intake and 0.52
(± 0.63) and 0.81 (± 0.98) for feed efficiency respectively. Existence of major
gene was determined by examining the highest probability density regions.
Although the major gene has been identified for body weight and feed intake,
this result is not confirmed by the Mendelian transmission probabilities.

The aim of this study was to compare the
effectiveness of panoramic, periapical and two different Cone Beam Computed
Tomography (CBCT) devices in the detection of dental caries of dog teeth ex vivo. A total of 880 teeth were
investigated, 33 of which were with caries, whereas; 33 healthy teeth were the
controls. Periapical, panoramic and CBCT scans were made for the assessment of
the teeth. All images were evaluated separately by two observers experienced in
image interpretation. The presence or absence of occlusal caries was scored
using a 5-point scale. Kappa values were calculated to assess intra and
interobserver agreement. Receiver Operating Characteristic (ROC) analysis
was performed to compare the effectiveness of different imaging methods in the
detection of dental caries. For both observers, the order of success of the
image sets in the estimation of the caries tooth was CBCT Morita, CBCT Iluma,
periapical and panoramic radiograph (Area Under Curve (AUC): 0.929, 0.882,
0.861, and 0.704 for observer 1, AUC: 0.927, 0.896, 0.875, and 0.693 for
observer 2, respectively). CBCT was found to be the best
imaging method for the ex vivo detection of caries in dog teeth. In
addition, panoramic images performed worse than all other modalities.

Published: August 2019

Chronic kidney disease (CKD) and mineral disorders are one of the most common reasons of cats. Alterations in mineral metabolism occur in early stage of CKD and increasing the severity in advanced stages. In Turkey, although some clinical studies on CKD in cats are available, no data concerning the clinical significance of pretreatment Ca-P solubility product is present. The purpose of the current study was to determine of Ca-P solubility product and its association with the life quality of cats with CKD. Staging system for classifying cats with chronic kidney disease was based on IRIS guideline. The following groups were occurred based on serum creatinine (SCr) and urine specific gravity < 1035: Stage 2= SCr 1.6 - 2.8 mg/dl; Stage 3= SCr 2.9 - 5.0 mg/dl; Stage 4= SCr > 5.0 mg/dl. Solubility product (calcium x phosphorus) was also defined. Although calcium levels were within reference ranges in groups, Ca-P product were above 72 mg2/dl2 in stage 3 and 4 cats. In conclusion, determination of pretreatment Ca-P solubility product in cats with different stages of CKD could be useful to modify and manage the life quality of cats with CKD.

The purpose of
this study was to determine the phenotypic antibiotic susceptibility patterns,
extended-spectrum β-lactamase (ESBL) genes and genotypic profiles of
ESBL-positive Escherichia coli
strains isolated from urine samples obtained from outpatients with urinary
tract infection in Turkey. A total of 120 E.
coli strains during 2017, 2018, and 2019 (40 patients per year) were
examined for antibiotic susceptibility patterns by disc diffusion method, for
ESBL genes using PCR and sequencing and for molecular typing by pulsed-field
gel electrophoresis (PFGE) method. The isolates were evaluated for their
sensitivity to 21 different antibiotics. Four different antimicrobial
resistance patterns were determined according to antibiotic susceptibility
status of the isolates. The β-lactamase genes detected in the isolates were
CTX-M-15 + OXA-1 (n= 14), CTX-M-15 (n= 24), TEM-1 + CTX-M-15 (n= 52), TEM-1 +
SHV-12 (n=6), SHV-12 1 (n= 6), TEM-1 + CTX-M-1 (n= 6), TEM-1 + CTX-M-16 (n= 6)
and TEM-1 + CTX-M-9 (n= 6). The CTX-M-15 was the most prevalent ESBL enzyme in
the isolates. As a result of PFGE analysis performed by XbaI enzyme restriction
process, one major PFGE profile and three main groups (Group I-II-III) were
observed. While antibiotic resistance profiles of the strains showed four
groups (RI-RII-RIII-RIV), PFGE band profiles showed a major group (90%
similarity ratio). High ESBL production and decreased susceptibility to
broad-spectrum cephalosporins were observed in E. coli strains. In addition, PFGE analysis showed high clonal
similarity among E. coli isolates.

Authors: Guo Y. , Sun J. , Guo F. , He Yu. , Chen P.
Published: August 2019

The Friedel-Crafts acylation of 2-methoxynaphthalene (2-MN) with acetic anhydride (AA) was carried out in the ionic liquid (IL) butylpyridinium tetrafluoroborate ([BPy]BF4) using phosphotungstic acid (H3PW12O40) as the catalyst. The [BPy]BF4-mediated 2-MN acylation displays good conversion and selectivity towards 1-acyl-2-methoxynaphthalene (1-AC-2-MN), with 70.4% conversion of 2-MN and 96.4% selectivity to 1-AC-2-MN obtained under the optimal conditions. Owing to the rearrangement of 1-AC-2-MN, 6-acyl-2-methoxynaphthalene (6-AC-2-MN) can be detected after 1 h of reaction time, with the highest 6-AC-2-MN yield of 11.3% obtained under the examined reaction conditions. The system can be recycled and reused at least 6 times without significant loss of activity, indicating the good stability of the H3PW12O40/[BPy]BF4 catalytic system.

An investigation on the unsteady MHD natural convection heat and mass transfer flow of an electrically conducting, viscous, incompressible, chemically reactive and heat-absorbing nanofluid of Brinkman type past an exponentially accelerated moving vertical plate with ramped wall temperature and ramped surface concentration is carried out. Governing equations are non-dimensionalized and Laplace Transform Technique is used to find the exact solutions for fluid velocity, fluid temperature and species concentration. The quantities of physical interest, i.e. skin friction, rates of heat and mass transfers at the plate are also calculated. Numerical results for the velocity, temperature and species concentration of the fluid are demonstrated with the help of graphs whereas those of skin friction, rate of heat and mass transfers at the plate are displayed in tables for various flow parameters.

Published: August 2019

Our goal in this attempt is to model a nonlinear stretchable flow of a radiative viscous liquid with magnetohydrodynamics. Flow caused is due to a unsteady stretching surface with variable thickness. Consideration of thermal radiation effect characterizes the heat transfer process. Induced electric and magnetic fields are not accounted for. Appropriate transformations gave nonlinear systems. Modern methodology, i.e., НAM, is implemented for the computational process. Velocity and temperature are plotted for influential variables which are important in this problem. Moreover, surface drag force and heat transfer rate are computed and discussed. Velocity field is noted to decay the function of the larger Hartman number whereas opposite situation for temperature is examined via larger radiation parameter.

Published: August 2019

Bi12TiO20 (BTO) single crystals in pristine state and doped with ruthenium and rhodium are grown by the top-seeded solution growth method and characterized by optical and Raman spectroscopy. The effect of doping on the vibrational and optical properties is studied. The doped crystals show higher absorption in the visible spectral range and higher transmission in the near infrared region as compared to pristine BTO. The performed spatially resolved polarized Raman measurements reveal no significant doping-induced shift of vibrational modes while differences in the LO/TO intensity ratio of the tetrahedral asymmetric stretching vibration are encountered. The observations are discussed in terms of lattice ordering and dopant oxidation states.
Theoretical insight to intermolecular hydrogen bond interactions between methyl N-(2-pyridyl) carbamate and acetic acid: substituent effects, cooperativity and energy decomposition analysis
Authors: Chalanchi S. M. , Ebrahimi A. , Nowroozi A.
Published: August 2019

In the present work, the hydrogen bond (HB) interactions between substituted syn and anti rotamers of methyl N-(2-pyridyl) carbamate and acetic acid were investigated using quantum mechanical (QM) calculations. The rotamers have two typical active sites to form hydrogen bonds with acetic acid, such that four stable complexes are found on the potential energy surface. The complexes in which the oxygen atom of carbamate acts as proton acceptor are stabilized by EWSs and are destabilized by EDSs. The trend in the effects of substituents is reversed in the other two complexes, in which the nitrogen atom of ring is involved in the interaction. According to energy data, the substituent effects on the interaction energy can be expressed by Hammett constants. The natural resonance theory (NRT) model was used to investigate the charge distribution on the carbamate group and to discuss the interaction energies. The individual HB energies were estimated to evaluate their cooperative contributions on the interaction energies of the complexes. In addition, the localized molecular orbital energy decomposition analyses (LMO-EDA) demonstrate that the electrostatic interactions are the most important stabilizing components of interactions.
Optimization of high ultrasound-assisted extraction (INEFU) of active components from natural materials by response HPLC-PDA analysis
Authors: Seo S. B. , Kim Y. M.
Published: August 2019

High ultrasonic-assisted extraction technology (INEFU) was employed to extract the active components from natural materials (green coffee beans, Citrus madurensis, Centella asiatica, Laminaria Japonica). The extraction conditions were optimized by a response surface method and Box-Behnken design. The active component yields were obtained under the optimum parameters: ultrasound power (1800 watts), ultrasonication time, and particle size. After INEFU of natural materials (green coffee beans, Citrus madurensis, Centella asiatica and Laminaria Japonica) the products were analyzed with high performance liquid chromatography (HPLC). HPLC analysis showed that the four natural materials were composed of different combinations of vitamin C, polyphenols, chlorogenic acid, caffein, caffeic acid, asiaticoside and alginic acid. In addition, the INEFU results showed that natural materials can yield more active components during a simulated extraction process.

Published: August 2019

Background: There appears to be a global change in the role of physiotherapists (most especially) in serving as supplementary prescribers of relevant drugs.Objectives: This study aimed to determine the opinion of physiotherapists on enlistment as supplementary prescribers of drugs, and the classes of drugs they would like to prescribe.Methods: 102 licensed physiotherapists from 5 purposively selected hospitals participated in the study. A self administered questionnaire was used to collect the data. Data were analyzed using descriptive statistics and Kruskal Wallis test.Results: Eighty-three physiotherapists (83.8%) wanted to be enlisted as supplementary prescribers and most would like to prescribe analgesics (74.8%), NSAIDS (74.8%) and muscle relaxants (59.2%). Also, 89 respondents (86.4%) supported the enactment of a law that will protect physiotherapists in case of professional litigation. A range of reasons were adduced for desiring to have a change in prescription status and these include effectiveness of clinical practice (77.7%), image improvement (67.0%) and the increased benefit for patients (82.5%). The number of respondents who would like to prescribe Analgesics, NSAIDS and Muscle relaxants were significantly higher than for other classes of drugs (P = 0.001). It was concluded that the majority of physiotherapists would want their status to change to that of supplementary prescribers. Also, most prescribers would like to prescribe analgesics and NSAIDS while a moderate number would like to prescribe muscle relaxants under the protection of an enabling law.

Published: August 2019

Workplace bullying is a well-documented phenomenon that has been associated with a number ofnegative consequences. However, employees face difficulty sharing their experiences of bully and many of such incidents go unreported. We have attempted to make the sharing less threatening in this research by developing some scenarios (depicting bully, extracted from the real-life situations) and asking the participants to 'imagine' themselves in similar situation of bully and feel it then complete a questionnaire for evaluating the emotional state. This way, we would not be able tostudy the direct psychological effects of bullying on employees however, this technique may enable us to see the moderation effect of (perceived) bullying on job commitment. This exercise would be neutral on people who were never bullied but it may trigger the post trauma in people who had been bullied and they may report their emotions similar to the emotions when they were bullied. We asked 290n people; working in different organizations of Karachi, Pakistan; to complete theactivity of imagination, reporting their emotional state, and their job commitment. Instruments used for this purpose included: especially developed organizational bullying scenarios, Positive and Negative Affect Schedule scale (PANAS; Watson & Clark, 1988) and Organization Commitment Scale (OCS; Cook & Wall, 1974). Findings suggested that bullying at workplace is related to both an increased negative effect and a decreased job commitment. If employees relating these perceived bullying incidents to negative emotions and lower job commitment then it may be detrimental in real situations.
