Solution of a production process with the application of simulation: A case study
Authors: Mikušová Nikoleta , Petrović Milenko , Mitrik Vladimír , Šarišský Richard 
Published: October 2021

Abstract
Simulation programs are increasingly being used to solve material flow problems. These programs are primarily used for the simulation of production or transport processes. Testing of a new type of control in-process would mean stopping production and testing experiments with uncertain results. To avoid this lengthy and above all expensive way of any change, simulation programs have been used. Simulations of production processes in these programs enable better production planning and examination of bottlenecks in the production process by proposing changes, such as robots, conveyors, or also various logistics controls. The advantage is not only the fact that the production does not have to be interrupted, but also that it is possible to try many different experiments in a simulation process. The article is focused on the analysis of the production process in a selected production enterprise. After the analysis, the Tecnomatix Plant Simulation program was used for the creation of production process simulation. Results and improvements to the production process were proposed from the initial simulation with a focus on practical use.

Effect of moisture content on dielectric properties of banana leaves and peels in frequency range of 1–20 GHz
Authors: Pattanayak Soumya Sundar , Biswas Soumen 
Published: October 2021

AbstractThe quality of agricultural products can be remotely sensed and enhanced by determining the dielectric properties. This paper studies the dielectric properties of banana leaf and banana peel over the frequency range 1–20 GHz using the open-ended coaxial probe (OCP) method. A new curve fitting model is proposed to characterize the dielectric properties of banana leaf and banana peel. The different moisture content (MC) levels are considered for both banana leaf and banana peel samples and, their dielectric properties are characterized. Further, the banana leaf and banana peel’s measurement data are compared with the data obtained using the proposed model. In addition, Root Mean Square Error (RMSE) and R-squared (R2) are calculated to validate the performance of the proposed model. In case of banana leaf at 68.26% MC, the dielectric constant achieves the value ofR2and RMSE of 0.98 and 0.0648, respectively. Similarly, dielectric loss achieves the value ofR2and RMSE of 0.88 and 0.0795, respectively. Further, for banana peel at 80.89% MC, the dielectric constant achieves the value ofR2and RMSE of 0.99 and 0.2989, respectively. Similarly, dielectric loss achieves the value ofR2and RMSE of 0.96 and 0.6132, respectively.
Delignification of unbleached pulp by ternary deep eutectic solvents
Authors: Majová Veronika , Jablonský Michal , Lelovský Marek 
Published: October 2021

Abstract
The processing of lignocellulosic materials is very limited because of their low solubility in water and some organic solvents. Fifteen ternary deep eutectic solvents (DESs) were prepared and tested as solvents suitable for delignification of unbleached pulp. The selected ternary DESs are composed of quaternary ammonium salts and amino acids as hydrogen-bond acceptors, and organic acids and polyvalent alcohols as hydrogen bond donors, with molar ratios varying for the individual components. The delignification efficiency is significantly influenced by the degree of penetration of the solvent into the pulp fibre structure. Therefore, the density and viscosity analysis of individual solvents was performed. Unbleached beech pulp with initial kappa number 13.9 was treated with the prepared DESs. The kappa number indicates the residual lignin content or the bleachability of pulp. The efficiency of the solvents ranged from 1.4% to 28.1%. The most suitable for the pretreatment of fibres, based on lignin removal efficiency, were found to be three DESs, in the following order: malonic acid/choline chloride/1,3-propanediol (1:1:3) > choline chloride/acetamide/lactic acid (1:2:3) > choline chloride/urea/lactic acid (1:2:3).

Abstract

Objectives
The aim of this study is to investigate clinical features of atypical pulmonary tuberculosis (aPTB) mimicking bacterial pneumonia, determine imaging features with the highest degree of correlation, and identify predictors for acid-fast bacilli (AFB) positivity.

Methods
The clinical data of 259 patients considered as aPTB were retrospectively analyzed. The correlation of CT patterns was evaluated with Spearman analysis, and the predictors for AFB positivity were assessed with the multivariate analysis.

Results
The most common symptom of aPTB was cough (84.6%), followed by fever and anorexia (47.1 and 41.7%, respectively). Infiltrated patchy was the most common radiological pattern (84.9%), followed by nodules (3–10 mm), micronodules (<3 mm), and consolidation (79.2, 78.8, and 66.0%, respectively). Nodules (3–10 mm) and micronodules (r = 0.988, p < 0.001), consolidation and air bronchogram (r = 0.590, p < 0.001), and pulmonary atelectasis and consolidation (r = 0.323, p < 0.001) showed high correlation. In the multivariate analysis, hyperpyrexia (OR, 2.29; 95% CI, 1.22–4.29) and bronchiectasis (OR, 2.06; 95% CI, 1.04–4.06) were the predictors of AFB-smear positivity, while bulla (OR, 0.22; 95% CI, 0.05–0.97) was the predictor of AFB-smear negativity.

Conclusion
This study demonstrated the clinical and radiological features of aPTB mimicking pneumonia. Several paired radiological findings may guide us to the diagnosis of aPTB. Hyperpyrexia and bronchiectasis may be helpful for predicting AFB positivity, and bulla may be a predictive sign of AFB negativity.
Reassessing the Literature on the Relationship Between Financial Structure and Economic Growth
Authors: Xu Guangdong 
Published: October 2021

Abstract
This paper surveys the literature, particularly the empirical literature, that examines the association between financial structure and economic growth. The studies are divided into two groups depending on their research focus and research design. Whereas both strands of literature contribute to our understanding of the relationship between financial structure and growth and may also inform each other, the fundamental difference in their research questions means that they should be treated separately rather than together. Despite this difference, the two strands of literature share a common weakness: i.e. they overlook the interactions between banks and stock markets, which may lead to biased estimations.
Empirical Analysis of the Effect of Fiscal Policy Shocks in China
Authors: Ji Jia 
Published: October 2021

AbstractThe central issues concerning fiscal policy makers include macroeconomic stability and growth stimulation. The policy decision process is facilitated by investigation on the effects of fiscal policy, such as a change in government spending or taxes on macroeconomic variables comprising inflation, aggregate output, and interest rates. Build on the Blanchard-Perotti identification approach, this paper empirically analyses the influence of fiscal policy to aggregate economic activities in China, and the estimated results are compared between China and the advanced economies. The findings demonstrate that the impulse responses incurred by tax shocks are generally stimulative, although government spending shocks tend to be neutral, revealing meaningful implications for the fiscal space and policy design.
PbCN2 – an elucidation of its modifications and morphologies
Authors: Braun Cordula , Mereacre Liuda , Ehrenberg Helmut 
Published: October 2021

Abstract
Concerning the crystal structure of PbCN2 there exist two different descriptions in the literature, one based on the non-centrosymmetric structure, space group Pna21, another one on the centrosymmetric one in space group Pnma. To elucidate the conditions for their appearance, comprehensive preparative and structural investigations have been conducted which proved the existence of two distinct modifications of PbCN2. A detailed comparison of the two phases is provided. The growth conditions and crystallization processes of the two PbCN2 structures are reported with focus on the influence of the pH value on the products. Depending on the growth conditions several different morphologies arise, namely PbCN2 in needle-shaped and platelet-shaped crystals, as well as pompon-shaped and lance-shaped crystals.

Distinct Fastigial Output Channels and Their Impact on Temporal Lobe Seizures
Authors: Streng Martha L. , Tetzlaff Madison R. , Krook-Magnuson Esther 
Published: October 2021

Despite being canonically considered a motor control structure, the cerebellum is increasingly recognized for important roles in processes beyond this traditional framework, including seizure suppression. Excitatory fastigial neurons project to a large number of downstream targets, and it is unclear whether this broad targeting underlies seizure suppression, or whether a specific output may be sufficient. To address this question, we used the intrahippocampal kainic acid mouse model of temporal lobe epilepsy, male and female animals, and a dual-virus approach to selectively label and manipulate fastigial outputs. We examined fastigial neurons projecting to the superior colliculus, medullary reticular formation, and central lateral nucleus of the thalamus, and found that these comprise largely nonoverlapping populations of neurons that send collaterals to unique sets of additional, somewhat overlapping, thalamic and brainstem regions. We found that neither optogenetic stimulation of superior colliculus nor reticular formation output channels attenuated hippocampal seizures. In contrast, on-demand stimulation of fastigial neurons targeting the central lateral nucleus robustly inhibited seizures. Our results indicate that fastigial control of hippocampal seizures does not require simultaneous modulation of many fastigial output channels. Rather, selective modulation of the fastigial output channel to the central lateral thalamus, specifically, is sufficient for seizure control. More broadly, our data highlight the concept of specific cerebellar output channels, whereby discrete cerebellar nucleus neurons project to specific aggregates of downstream targets, with important consequences for therapeutic interventions.SIGNIFICANCE STATEMENTThe cerebellum has an emerging relationship with nonmotor systems and may represent a powerful target for therapeutic intervention in temporal lobe epilepsy. We find, as previously reported, that fastigial neurons project to numerous brain regions via largely segregated output channels, and that projection targets cannot be predicted simply by somatic locations within the nucleus. We further find that on-demand optogenetic excitation of fastigial neurons projecting to the central lateral nucleus of the thalamus—but not fastigial neurons projecting to the reticular formation, superior colliculus, or ventral lateral thalamus—is sufficient to attenuate hippocampal seizures.
Overexpressing Histone Deacetylase 5 in Rat Dorsal Striatum Alters Reward-Guided Decision-Making and Associated Neural Encoding

Published: October 2021

Accumulating evidence in the past decade implicates histone-modifying enzymes, such as class I histone deacetylases (HDACs), in learning and memory and, recently, habit formation. However, it is unclear whether HDACs play roles in complex cognitive function. To address this issue, we examined the role of dorsal striatal HDAC5, a class II HDAC, in reward-guided decision-making and associated neural encoding in rats. We first injected adeno-associated virus to overexpress a nuclear-localized HDAC5 in dorsal striatum (DS). We then recorded neural correlates from dorsolateral striatum (DLS) as rats performed two reward-guided choice tasks, in which we manipulated either the size of or delay to reward. During these tasks, rats first learned which of two options led to the better reward and then reversed those contingencies in a second block of trials. We found that rats with HDAC5 overexpression in DS responded faster and chose higher value reward more often during the first block of trials but were less able to reverse those contingencies in the second block of trials. At the neural level, HDAC5 overexpression in DS elevated and reduced the number of cells in DLS that increased firing to stimuli and reward, respectively, and shifted encoding toward cues that predicted more immediate reward. These results suggest that the HDAC5 overexpression in DS contributes to inflexible decision-making, demonstrating a role of histone-modifying enzymes in complex cognitive function.SIGNIFICANCE STATEMENTHDACs are important for learning and habit formation. Here, we expanded on these functions and found that overexpression of HDAC5 produced faster and more automatic behavior, and related changes in dorsolateral striatal neural firing in rats performing a value-based decision-making task. These results implicate HDAC5 as a potential therapeutic target for psychiatric conditions that impair decision-making and executive function.

Watershed subdivision and weather input effect on streamflow simulation using SWAT model
Authors: Alsilibe Firas , Bene Katalin 
Published: October 2021

Abstract
In watershed modeling research, it is practical to subdivide a watershed into smaller units or sub-watersheds for modeling purposes. The ability of a model to simulate the watershed system depends on how well watershed processes are represented by the model and how well the watershed system is described by model input. This study is conducted to evaluate the impact of watershed subdivision and different weather input datasets on streamflow simulations using the soil and water assessment tool model. For this purpose, Cuhai-Bakonyér watershed was chosen as a study area. Two climate databases and four subdivision variations levels were evaluated. The model streamflow predictions slightly effected by subdivision impact. The climate datasets showed significant differences in streamflow predictions.

Published: October 2021

Abstract
In Hungary a lot of people live in condominiums or in block of flats where fire often occurs despite of precise design and effective fire protection arrangements. This means a hazard for the people living there, for the building constructions and also for the environment. A deeper knowledge of the burning process and examining the negative effects of fire load on building constructions with scientific methods are actual questions nowadays. In order to get to know the phenomena more accurately, fire spread in a bedroom was modeled and numerical simulation was carried out, which is presented in this paper in detail. These experiences may help increasing the fire safety and preventing fires in apartments. The simulations were carried out considering the characteristics of the Hungarian architecture.
Eye Movements during dynamic scene viewing are affected by visual attention skills and events of the scene: Evidence from first-person shooter gameplay videos
Authors: Holm Suvi , Häikiö Tuomo , Olli Konstantin , Kaakinen Johanna 
Published: October 2021

The role of individual differences during dynamic scene viewing was explored. Participants (N=38) watched a gameplay video of a first-person shooter (FPS) videogame while their eye movements were recorded. In addition, the participants’ skills in three visual attention tasks (attentional blink, visual search, and multiple object tracking) were assessed. The results showed that individual differences in visual attention tasks were associated with eye movement patterns observed during viewing of the gameplay video. The differences were noted in four eye movement measures: number of fixations, fixation durations, saccade amplitudes and fixation distances from the center of the screen. The individual differences showed during specific events of the video as well as during the video as a whole. The results highlight that an unedited, fast-paced and cluttered dynamic scene can bring about individual differences in dynamic scene viewing.

Evaluación Económica Proyecto Túnel y Accesos en Sierra de Marquesado, San Juan – Argentina.
Authors: Bustos Marcelo Gastón , Girardi Mancini Pablo 
Published: October 2021

This paper describes the methodology applied for the economic assessment of a projected tunnel that will cross the range “Sierra de Marquesado”, west of the city of San Juan, Argentina. Through this tunnel and its accesses, there would be a faster and more direct connection between the main populated centers located on both sides of the mountain range. The tunnel would also serve to give way to the future Gran Tulum aqueduct, and to a future pipeline intended to carry natural gas, significantly shortening the layout of them. A number of hypotheses have been raised to quantify the benefits and costs associated with the tunnel project and its accesses, considering the alternatives of asphalt and concrete pavements.
Vehicle operating costs and travel times were quantified using HDM-4, and a sensitivity analysis of economic indicators was finally carried out, for different scenarios with increased costs and reduced benefits.
Results clearly show the technical and economic convenience of the construction of this tunnel, which should contribute significantly to the socio-economic development of the region.
The relationship between uric acid to high-density lipoprotein cholesterol ratio and collateral index in patients with chronic total occlusion
Authors: Aydın Cihan , Emlek Nadir 
Published: October 2021

Background High serum uric acid (UA) levels and low high-density lipoprotein cholesterol (HDL–C) levels are accepted as risk factors for cardiovascular mortality. Hyperuricemia and low HDL–C levels were associated with an increased risk of cardiovascular mortality and the development of diabetes and hypertension. However, the association of UA with cardiovascular (CV) mortality,collateral index are undetermined in patients with chronic total occlusion (CTO).Material and methods 124 patients who underwent coronary angiography with the diagnosis of stable or unstable angina pectoris and had chronic total occlusion were included in our study. Blood samples were collected from all patients before the angiography procedure. Coronary collateral circulation (CCC) was graded according to the Rentrop grading system of 0–3. Rentrop grades of 0 and 1 indicated low-grade CCC group, whereas grades 2 and 3 indicated high-grade CCC group. We divided our patients into two groups as low-grade CCC and high-grade CCC and examined these two groups in terms of uric acid / HDL ratios. Group 1: Rentrop classification grade 0–1 (mean age, 63,9±9,9), Group 2: Rentrop classification grade 2–3 (mean age, 62,1±9,4).Results The baseline characteristics were similar in both groups. Uric acid / High density lipoprotein-cholesterol ratios and uric acid levels were higher in group 1 with poor collateral circulation [group 1; 0,21 (0,07–0,39) vs. group 2; 0,16 (0,08–0,31), group 1; 8,2 (3,4–10,4) vs. group 2; 5,85 (3,5–7,7), p<0,001, p<0,001 respectively].Conclusions We found that high Uric acid / High-density lipoprotein-cholesterol ratios and high uric acid levels are associated with poor collateral circulation.
