ANALISIS CREDIT SCORING TERHADAP STATUS PEMBAYARAN BARANG ELEKTRONIK DAN FURNITURE MENGGUNAKAN BOOTSTRAP AGGREGATING K-NEAREST NEIGHBOR

Classification is the process of grouping objects that have the same characteristics into several categories. This study applies a combination of classification algorithms, namely Bootstrap Aggregating K-Nearest Neighbor in credit scoring analysis. The aim is to classify the credit payment status of electronic goods and furniture at PT KB Finansia Multi Finance in 2020 and determine the level of accuracy produced. Credit payment status is grouped into 2 categories, namely smoothly and not smoothly. There are 7 independent variables that are used to describe the characteristics of the debtor, namely age, number of dependents, length of stay, years of service, income, amount of payment, and payment period. The application of the classification algorithm at the credit scoring analysis is expected to assist creditors in making decisions to accept or reject credit applications from prospective debtors. The results showed that the accuracy obtained from the Bootstrap Aggregating K-Nearest Neighbor algorithm with a proportion of 90:10, m=80%, C=73, and K=5 was the best, which was 92.308%.

The Chinese pond mussel Sinanodonta woodiana demographically outperforms European native mussels

Unionid mussels are essential for the integrity of freshwater ecosystems but show rapid worldwide declines. The large-sized, thermophilic Chinese pond mussel Sinanodonta woodiana s.l., however, is a successful global invader, spread with commercially traded fish encysted with mussel larvae; its negative impacts on native mussels are expected. Here, we exploit a natural experiment provided by a simultaneous introduction of S. woodiana and four species of native unionids for water filtration to a pond in north-eastern Poland. Sinanodonta woodiana established a self-sustaining population and persisted for 19 years in suboptimal thermal conditions (mean annual temperature, 7.4 °C; mean temperature of the coldest month, − 3.7 °C, 73-day mean yearly ice-formation), extending the known limits of its cold tolerance. Over four study years, its frequency increased, and it showed higher potential for population growth than the native mussels, indicating possible future dominance shifts. Outbreaks of such sleeper populations are likely to be triggered by increasing temperatures. Additionally, our study documents the broad tolerance of S. woodiana concerning bottom sediments. It also points to the importance of intentional introductions of adult individuals and the bridgehead effect facilitating its further spread. We argue that S. woodiana should be urgently included in invasive species monitoring and management programmes.

Prospecting black hole thermodynamics with fractional quantum mechanics

This paper investigates whether the framework of fractional quantum mechanics can broaden our perspective of black hole thermodynamics. Concretely, we employ a space-fractional derivative (Riesz in Acta Math 81:1, 1949) as our main tool. Moreover, we restrict our analysis to the case of a Schwarzschild configuration. From a subsequently modified Wheeler–DeWitt equation, we retrieve the corresponding expressions for specific observables. Namely, the black hole mass spectrum, M, its temperature T, and entropy, S. We find that these bear consequential alterations conveyed through a fractional parameter, $$\alpha $$ α . In particular, the standard results are recovered in the specific limit $$\alpha =2$$ α = 2 . Furthermore, we elaborate how generalizations of the entropy-area relation suggested by Tsallis and Cirto (Eur Phys J C 73:2487, 2013) and Barrow (Phys Lett B 808:135643, 2020) acquire a complementary interpretation in terms of a fractional point of view. A thorough discussion of our results is presented.

Optimization of bronchial asthma treatment according to polymorphism in the leukotriene-C4 synthase gene

The aim of the study was to investigate the effectiveness of different schemes of basic asthma therapy depending on the polymorphism of the LTC4 gene. Materials and methods. 181 patients with asthma were recruited to participate in the study. All patients included in the study underwent a general clinical study, spirometry, the level of asthma control was determined by Asthma control questionnaire 5 (ACQ-5), by studying the polymorphism of the LTC4 gene, it was determined that patients belong to the A/A, A/C and C/C genotypes. Results. Allelic -444C polymorphism of the LTC4-S gene (rs 730012) had the following genotype frequency among asthma patients: A/A – 77 people (42.6 %), A/C – 73 people (40.3 %) and C/C – 31 people (17.1 %). In groups of patients with genotypes A/A and A/C, during treatment with a low dose of ICS and montelukast, there was a significant improvement in FEV1 and the score according to the ACQ-5 questionnaire (asthma control level). However, in the group of patients with the C/C genotype, there were no significant changes in FEV1 and the score according to the ACQ-5 questionnaire. In the groups of patients with genotypes A/A and C/C on the background of increasing the dose of ICS to medium in a fixed combination with LABA compared with the results of treatment with low-dose ICS and montelukast, there was a significant improvement in FEV1 and asthma control – ACQ- 5. At the same time, in the group of patients with genotype A/C, there were no reliable indicators of FEV1 and ACQ-5 score changes. Conclusions. The frequency of genotypes A/A, A/C and C/C for LTC4S polymorphism in the studied population are 42.6 %, 40.3 % and 17.1 %, respectively. Patients with genotypes A/A and C/C have a significant response to treatment with a low dose of ICS and montelukast in the form of an improvement in FEV1 and ACQ-5 score. Increasing the dose of ICS up to moderate in a fixed combination with β2-LABA in groups of patients with genotypes A/A and C/C leads to a significant improvement in the FEV1, as well as in the asthma control level - ACQ-5

Ámbito material del Reglamento Bruselas I bis, prácticas comerciales desleales (B2C) y acciones colectivas de cesación: comentario a la STJUE MOVIC BV (C-73/19)

La STJUE Movic BV contiene cuestiones relativas al Derecho internacional privado europeo (DIPr) y al Derecho derivado de prácticas comerciales desleales y de consumo de la UE. Uno de sus aspectos más interesantes es la interpretación del concepto europeo de “materia civil y mercantil” del Reglamento Bruselas I bis. Un concepto que lejos de ser pacífico ha generado numerosas cuestiones de tipo prejudicial al Tribunal de Justicia de la Unión Europea por parte de tribunales y autoridades de los Estados miembros desde los orígenes de este (i.e.: Convenio de Bruselas de 1968) en todos instrumentos del DIPr patrimonial europeo. La materia objeto del litigio depende de ser caracterizada como materia “civil y mercantil” para entender que tiene cabida en el ámbito material del Reglamento Bruselas I bis. Para ello, los tribunales tienen que considerar dos elementos clave que el TJUE ha ofrecido en esta juris-prudencia sobre el concepto “materia civil y mercantil” y que en este asunto, se vuelven a traer a colación.De otra parte, en relación con el Derecho derivado de consumo, siendo parte de su contenido la regulación de las prácticas comerciales desleales contra los consumidores, el asunto Movic BV, también se hace eco de aspectos controvertidos cómo son es la naturaleza de las acciones transfronterizas de cesación atendiendo al complejo entramado y relación de normas de este acquis communautaire.

Processing Parameters for One-Pass Drying of High-Moisture Parboiled Rough Rice with 915 MHz Microwaves

HighlightsThe impact of parboiling process parameters on the feasibility of one-pass microwave drying of high-moisture parboiled rough rice was investigated.Rough rice was parboiled by 3 hours of soaking in water at 71°C, 73°C, or 76°C and then steamed for 5, 10, or 15 min prior to microwave drying at 915 MHz.Moisture content following parboiling at the studied conditions ranged from 42.59% to 48.21% dry basis.Microwave specific energies ranging from 0.04 to 0.29 kWh per kg of parboiled rough rice dry matter (kWh kg-DM-1) were used to dry the parboiled rough rice.Soaking at 73°C and steaming for 10 min followed by one-pass microwave drying at 0.29 kWh kg-DM-1 gave the best results in terms of parboiled rough rice final moisture content and post-drying milling and physiochemical properties.Microwave treatment can provide one-pass drying of parboiled rough rice.Abstract. The volumetric heating phenomenon of microwaves (MW) offers a means to quickly dry high moisture content (MC) parboiled rough rice in one pass. However, to successfully dry parboiled rough rice in one pass using MW while preserving the milled rice yield and quality characteristics, it is vital to investigate the impacts of the pre-drying parboiling conditions on the drying process and the resulting product characteristics. The objectives of this study were to explore the feasibility of using MW at 915 MHz to dry high-MC parboiled rough rice and to determine the implications of the pre-drying soaking and steaming conditions on the parboiled rough rice final moisture content (FMC), milled rice yield (MRY), head rice yield (HRY), and the milled rice physiochemical properties. Freshly harvested, long-grain rough rice of the cultivar Mermentau at MC of 31.58% dry basis (d.b.) was used in this study. The parboiling process involved soaking the rough rice in water at temperatures of 71°C, 73°C, or 76°C and steaming for 5, 10, or 15 min. After parboiling, samples of rough rice for the controlled experiment were gently dried with natural air at 25°C and 65% relative humidity, while samples for MW treatment were dried using a 915 MHz MW dryer, which was set to deliver energy ranging from 0.04 to 0.29 kWh per kg of rough rice dry matter content (kWh kg-DM-1). The MW power applied during treatment ranged from 1 to 8 kW with heating durations of up to 6 min. The rough rice MC immediately increased after the soaking and steaming processes and ranged from 42.59% to 48.21% d.b. Increased soaking temperature led to increased uptake of water after parboiling, decreases in MRY, HRY, protein content, and milled rice surface lipid content (SLC), and increases in total color difference (TCD). Increased steaming duration led to decreased moisture uptake during steaming, decreased MRY, protein content, SLC, and TCD, and increased HRY. Increased MW specific energy led to decreased FMC, HRY, protein content, and SLC and increased TCD. It is recommended that long-grain rough rice should be soaked at 73°C, steamed for 10 min, and then treated at MW specific energy of 0.29 kWh kg-DM-1 in one pass to achieve parboiled rough rice FMC of 18.79% d.b., HRY of 69.33%, and desirable parboiled milled rice physicochemical and sensory properties. At the same parboiling conditions, the control samples had MRY of 74.98% and HRY of 74.07%. MW specific energy greater than 0.29 kWh kg-DM-1 was necessary to dry the parboiled rough rice to MC safe for long-term storage (14.29% to 15.61% d.b.). However, the application of specific energy beyond 0.29 kWh kg-DM-1 caused a reduction of HRY below that of the control samples. Therefore, to preserve HRY, rice processors should use MW specific energy of 0.29 kWh kg-DM-1 to partially dry parboiled rice and then complete the drying to a safe storage MC by using natural or slightly heated air. This study demonstrates the feasibility of using 915 MHz MW heating of high-MC parboiled rough rice to achieve one-pass drying. Keywords: 915 MHz microwaves, Milling yields, One-pass drying, Parboiled rough rice, Physicochemical properties, Rice quality.

Black Hole Entropy: A Closer Look

In many papers in the literature, author(s) express their perplexity concerning the fact that the ( 3 + 1 ) black-hole ‘thermodynamical’ entropy appears to be proportional to its area and not to its volume, and would therefore seemingly be nonextensive, or, to be more precise, subextensive. To discuss this question on more clear terms, a non-Boltzmannian entropic functional noted S δ was applied [Tsallis and Cirto, Eur. Phys. J. C 73, 2487 (2013)] to this complex system which exhibits the so-called area-law. However, some nontrivial physical points still remain open, which we revisit now. This discussion is also based on the fact that the well known Bekenstein-Hawking entropy can be expressed as being proportional to the event horizon area divided by the square of the Planck length.
