Synthetic route design & assessment using vectors derived from similarity and complexity
Authors: Howell Gareth , Genheden Samuel
Published: March 2024

With the aim of improving the machine-interpretation of synthetic routes we describe a new theoretical approach to visualising and assessing synthetic pathways in the absence of empirical data such as yield, cost and waste. The representation of molecular structures as coordinates derived from molecular (fingerprint) similarity and complexity allows individual transformations to be viewed as vectors (reactant to product) whereby the magnitude and direction of travel can be used to assess and quantify transformation efficiency. Vectors derived in this way are shown to follow logical trends when grouped by reaction type/class. Synthetic routes can thus be visualised as a series of head-to-tail vectors (one per transformation or step) traversing the range between starting material and target whereby the efficiency with which this range is covered can be quantified. Our approach is built upon the analysis of > 350k literature syntheses (> 1.4m reactions), is readily machine-interpretable and avoids the challenges associated with automated reaction class assignment and atom-mapping.
Strategie interdyscyplinarne w socjologii i historii
Authors: Kolasa-Nowak Agnieszka
Published: March 2024

Tematem artykułu jest analiza zagadnienia interdyscyplinarności na przykładzie przekraczania granic między socjologią i historią w polskiej akademii. Z perspektywy socjologii nauki rekonstruuję obecny stan relacji między tymi dyscyplinami, próby przekraczania granic i tworzenia środowisk badawczych pomiędzy socjologią a historią, takich jak socjologia historyczna, historia mówiona, historia kobiet i inne. Opisuję strategie interdyscyplinarne socjologów i historyków młodszego pokolenia, ich doświadczenia, przekonania oraz sposoby budowania karier naukowych. To, co dzieje się na obrzeżach dyscyplin naukowych, uruchamia procesy istotne dla ich tożsamości i autonomii, zmienia też relacje w całej konstelacji pól naukowych. Socjologia i historia są w Polsce bliskimi dyscyplinami o długiej tradycji wzajemnych odniesień, inspiracji i wpływów. Do charakterystyki ich obecnego stanu wykorzystałam także wypowiedzi socjologów i historyków zainteresowanych przekraczaniem granic. Zebrałam je w 36 wywiadach pogłębionych.

Published: March 2024

Celem tej analizy jest ustalenie, w jakim stopniu upodobania do różnych gatunków filmowych związane są z pozycją klasową, a więc podlegają prawidłowościom stwierdzonym dla innych wymiarów stylu życia. Materiałem empirycznym są dane z badania przeprowadzonego na reprezentatywnej próbie ogólnopolskiej w 2019 r. Okazuje się, że preferencje do określonych gatunków filmowych są stosunkowo słabym odzwierciedleniem podziałów klasowych. Potwierdzałoby to hipotezę, że zjawisko homologii między uczestniczeniem w kulturze a stratyfikacją klasową ogranicza się tylko do niektórych form aktywności. Drugi wniosek dotyczy odpowiedzi na pytanie, czy różne aktywności związane ze spędzaniem czasu wolnego łączą się ze sobą w syndromy kultury, co mogłoby być podłożem konsolidacji podziałów klasowych. Wyniki naszych analiz wskazują na występowanie pewnych zależności między oglądaniem filmów a innymi rodzajami spędzania czasu wolnego, ale są one raczej słabe, co świadczyłoby o tym, że preferencje filmowe nie stały się, jak dotąd, przestrzenią konsolidowania się hierarchii społecznej
Analysis of ontogenetic changes in head shape and diet in a catfish with moderately enlarged jaw adductors (Clariallabes melas)
Authors: Wyckmans Marisa , Herrel Anthony , Adriaens Dominique
Published: March 2024

Jaw adductor hypertrophy, or the presence of enlarged jaw-closing muscles, has arisen several times independently in African clariid catfish. Previous work has demonstrated that species characterized by enlarged jaw adductors may have unusual ways of foraging such as terrestrial foraging and prey capture, and often include a large proportion of hard and terrestrial prey in their diet. However, relatively little is known about species of the genus Clariallabes with an intermediate degree of jaw adductor hypertrophy. In the present study we present data on head shape and diet for a range of sizes of specimens of a poorly known species of Clariallabes, C. melas. Our data show that growth patterns in this species and the previously studied

C. longicauda are similar in some ways (e.g. positive allometry of the growth of the jaw muscles) but different in others (negative allometry in hyoid width). However, C. melas has a smaller head for its body size in all dimensions. Due to the large number of empty stomachs we encountered, dietary data remain preliminary, but suggest a varied diet including both hard and soft prey. Our data show that a large amount of variation in head shape may exist even among related species and that species with jaw adductor hypertrophy generally show positive allometry in the growth of the jaw adductors and associated structures. Whether jaw muscle hypertrophy is an adaptive trait in clariid catfish awaits further comparative analyses testing for the evolutionary association between jaw adductor hypertrophy and the inclusion of hard prey into the diet.

Published: March 2024

Okara is a by-product of the soymilk and tofu manufacturing industry. Recently, changes
in lifestyle and eating patterns led to higher demands for snack foods produced via
extrusion technology. Extruded products enriched with okara, which consists of high
dietary fibre content, can increase the nutritional quality of extruded snacks with higher
commercial values. This study aimed to determine the influence of okara levels; 0, 5, 10,
and 15% (w/w) on properties of extrudates in terms of fibre content, water activity, bulk
density, expansion ratio, colour, textural (hardness and crispness), and microstructure. The
increment of okara level resulted in the reduction of water activity, expansion ratio,
lightness, and crispness of extrudates while, soluble and insoluble dietary fibre content,
bulk density, and hardness were increased. Extrudate produced at higher levels of okara
had a rougher surface, smaller air cells, and thicker walls. A collapse in cell structure was
observed at 15% okara. In conclusion, fibre-enriched extrudate with desirable
characteristics can be obtained at a 5% okara level. This study provides a promising
application in harnessing the nutritional benefits of okara.

Analysis on the Effect of Yiqi Huoxue Decoction Combined with Neuromuscular Electrical Stimulation in Improving ICU-Acquired Debility in Mechanically Ventilated Patients
Authors: Jiang Fan
Published: March 2024

To investigate the effect of Yiqi Huoxue decoction combined with neuromuscular electrical stimulation on improving intensive care unit (ICU) acquired debility in mechanically ventilated patients. Methods: 50 patients who were admitted to the ICU and received mechanical ventilation treatment in our hospital from June 2022 to June 2023 and were complicated with ICU-acquired neurasthenia were selected, and randomly grouped using the randomized envelope method into two groups: a control group with 25 patients who received neuromuscular electrical stimulation alone; observation group with 25 patients who received the traditional Chinese medicine Yiqi Huoxue decoction. Comparison indexes: treatment efficiency, degree of emotional recovery (APACHE Ⅱ score), muscle strength status (MRC score), motor status (FAC rating), and self-care ability (BI index score). Results: The treatment efficiency of patients in the observation group patients was higher as compared to those in the control group (P < 0.05). There was no significant difference in the comparison of the results of the scores (ratings) of each index between the two groups before treatment (P > 0.05). After the treatment, the APACHE Ⅱ scores of patients in the observation group were significantly lower as compared to those in the control group, while the MRC scores, FAC ratings, and BI index scores were higher in the observation group than those of the control group patients (P < 0.05). Conclusion: The combined application of Yiqi Huoxue decoction and neuromuscular electrical stimulation in the treatment of patients with ICU-acquired neurasthenia complicated by mechanical ventilation significantly enhanced the clinical efficacy, the patient’s muscle strength, motor status, and ability of self-care. Hence, it has high application value and is worthy to be popularized.

Authors: Da Silva Gilson Santos , Santana Greg´ório Mateus , Gomes Ronaldo Lima , De Jesus Raildo Mota
Published: March 2024

Brazil is the world's leading producer of guarana and Bahia is the largest producing state, which suggests the need for cultivation planning. In this study, the physical-environmental factors of six municipalities in Lower Southern Bahia, Brazil were characterized to identify favorable areas for guarana cultivation. A database with the basic physical-environmental conditions was used to characterize and identify such areas. As described in the literature, the thresholds of conditioning factors for successful cultivation were selected using Structured Query Language (SQL) based on Geographic Information Systems (GIS), with logical operators and overlay tools. The factors considered in the analysis were soils (drainage and texture), climate (precipitation and temperature), and topography (slope). The results indicate the existence of favorable areas for guarana cultivation in Lower Southern Bahia, Brazil, which can significantly contribute to the planning and optimization of fruit cultivation in the region. A total of 23,489.7 hectares were considered favorable areas for guarana cultivation. This value is double the area allocated for cultivation in Brazil and more than four times the area allocated for harvesting in Bahia.

Este estudo é conduzido por duas equações empíricas utilizando as reanálises do ERA5 para determinar a climatologia do Nível de Condensação por Levantamento (NCL) da América do Sul (AS) de 1991 a 2021. Antes de calcular a climatologia NCL, o desempenho das equações empíricas é verificado através de um estudo de caso realizado entre 30 e 31 de dezembro de 2021. Embora os resultados das equações comparados aos dados de referência apresentem alguns desvios, eles não invalidam a aplicação das equações em um estudo climatológico. Os principais achados da climatologia revelaram que o NCL normalmente atinge maior altitude em 1800 Z. A estação durante a qual o NCL atinge sua altitude máxima varia dependendo das características climáticas da região analisada. Por exemplo, a maior altura do NCL foi observada durante o verão na Patagônia (4.000 m), a primavera no Nordeste do Brasil (3.000 m), o inverno no centro da África do Sul (2.000 m) e na Amazônia (1.500 m). Além disso, em cinco cidades estudadas em todo o Brasil, o NCL apresentou uma tendência positiva em sua altitude, que foi acompanhada por uma tendência negativa na precipitação.
SECONDARY SMALL INTESTINAL OBSTRUCTION ASSOCIATED WITH AN OMENTAL ADHESION AFTER END-TO-END JEJUNO-ILEAL ANASTOMOSIS IN A THOROUGHBRED HORSE: A CASE REPORT
Authors: Yoon Jungho , Kim Ahram , Park Jongyoung , Kwak Young Beom , Choi In-Soo , Park Taemook
Published: March 2024

A 19-month-old female thoroughbred horse presented with a history of acute abdominal pain. When the horse was four months of age, she underwent abdominal surgery and most of the strangulated jejunum and ileum were resected and anastomosed using an end-to-end technique. Subsequently, the horse was diagnosed with an ileal obstruction secondary to an adhesion of the greater omentum, which caused a mechanical obstruction of the lumen of the distal ileum. The ileum was released by transecting the adhesion and performing an omentectomy. After surgical intervention, the horse recovered quickly and was discharged fifteen days after surgery. This case report describes an ileal obstruction caused by an omental adhesion that formed after a jejunoileal anastomosis in a thoroughbred horse. The clinical, imaging, and surgical findings are described.

COVID-19 Wage Subsidy: Outcome Evaluation - Value for Money
Authors: Fyfe Caroline , Maré David C. , Taptiklis Phoebe
Published: March 2024

The value for money of the COVID-19 Wage Subsidy Support programme (WSS) was evaluated using cost-benefit analysis from a societal perspective, that encompassed the New Zealand economy as a whole. The subsidy was treated as a transfer (from the government into the wider NZ economy) and negative transfers - government money repaid or not spent, i.e.– subsidy repayments and unemployment support avoided - were subtracted from this. As the analysis was undertaken from a societal perspective, transfers were included as both a cost and a benefit, but with a 20% deadweight burden of raising tax revenue added to the cost side. The cost of administering the wage subsidy was also included. The quantified benefits of the wage subsidy were increased output associated with people remaining in employment, and the value of the wellbeing they experienced from avoiding unemployment. Outcomes were calculated by employment months gained over the short (6 month) and medium (12 month) term. The March 2020 wave had a favourable benefit-to-cost ratio of 1.20 after 6 months and 1.45 after 12 months. The 12-month ratio was 1.14 for the Extension wave, 0.83 for the Resurgence wave, and 1.63 for the March 2021 wave. Overall the COVID-19 wage subsidy represented value for money. It allowed more workers to remain in employment and more sole traders to remain in business, than was predicted would occur without a wage subsidy. To understand whether the effectiveness of the wage subsidy as an intervention remained stable over time, it is recommended that an evaluation be undertaken on the August 2021 wage subsidy. The value for money analysis could only identify direct benefits of the wage subsidy and so was limited to examining microeconomic outcomes. An investigation of fiscal interventions to mitigate the impact of the COVID-19 pandemic on the New Zealand economy is recommended to determine their effectiveness at a macroeconomic level.

ALGEBRAIC STRUCTURES ON A SET OF DISCRETE DYNAMICAL SYSTEM AND A SET OF PROFILE
Authors: Permatasari Ananda Ayu , Carnia Ema , Supriatna Asep Kuswandi
Published: March 2024

A discrete dynamical system is represented as a directed graph with graph nodes called states that can be seen on the dynamical map. This discrete dynamical system is symbolized by , where  is a finite set of states and the function g  is a function from  to . In the dynamical map, the discrete dynamical system has a height where the number of states in each height is called a profile. The set of discrete dynamical systems has an addition operation defined as a disjoint union on the graph and a multiplication operation defined as a tensor product on the graph. The set of discrete dynamical systems and the set of profiles are very interesting to observe from the algebraic point of view. Considering operation on the set of discrete dynamical systems and the set of profiles, we can see their algebraic structure. By recognizing the algebraic structure, it will be easy to solve the polynomial equation in the discrete dynamical system and in the profile. In this research, we will investigate the algebraic structure of discrete dynamical systems and the set of profiles. This research shows that the set of discrete dynamical system has an algebraic structure, which is a commutative semiring and the set of profiles has an algebraic structure, which is a commutative semiring and -semimodule. Moreover, both sets have the same property, which is isomorphic to the set of non-negative integers.
C PROGRAM AS A TOOL FOR THE TEACHING OF SECOND ORDER ORDINARY DIFFERENTIAL EQUATION
Authors: Amin Harahap , - Zahedi , Enus Lolang , Ansoruddin Ansoruddin , Wingkolatin Wingkolatin , Efendi Efendi
Published: March 2024

Second order ordinary differential equation (ODE) has many applications in science and engineering. Undergraduate students in science and engineering departments must study this subject in order to understand other subjects which are related to real applications they will encounter later. There are many excellent textbooks on differential equations where the students can study the theory and solve the problems. However, a textbook cannot give a quick answer for a problem particularly when the problem is quite difficult. A good choice is to use software such as Maple or Mathematica. However, this software is not always available for the teaching and purchasing it is usually beyond the ability of a student or even a lecturer. On the other hand, lecturers who want to create problems by themselves will follow the theory of the ODE. While creating the problems may not be difficult, answering them are harder. Problems which are very easy to answer are less worthless because they will not increase the students’ knowledge. Here comes the solution. A C program has been created to help lecturers create problems and solve them quickly. The program is interactive and can be easily understood by anyone who has basic theory of ODE. No knowledge of programming is needed; a user just runs it and follows the instruction. Students can also use the program to sharpen their knowledge. They can compare the solution of a problem they have solved with the answer given by the program. While commercial software such as Maple and Mathematica is very powerful, they cannot be used without writing necessary commands to solve a problem.
MAPPING OF GENDER INEQUALITY IN INDONESIA BASED ON INFLUENCING FACTORS USING GEOGRAPHICALLY WEIGHTED ORDINAL LOGISTIC REGRESSION
Authors: Khaulasari Hani , Suhaeri Fadjar
Published: March 2024

Gender inequality is a condition of discrimination between men and women that results from unequal social systems and structures. Gender inequality is measured based on the gender inequality index (IKG). This research aims to map gender inequality in Indonesia based on influencing factors and compare classification accuracy results between the GWOLR and ordinal logistic regression model. Data was obtained from the Indonesian Central Statistics Agency (BPS RI) and KemenPPPA in the year of 2022. The Gender Inequality Index data as the response variable is categorized using an ordinal data scale, namely IKG (1) Low, IKG (2) Middle, and IKG (3) High with ten predictor variables from the dimensions of health, education, human empowerment, socio-culture, and employment, with the amount of data is 34 observation data. The research method uses geographically weighted ordinal logistic regression (GWOLR) based on exponential kernel weighting. In the data analysis stage, ordinal logistic regression is performed before applying GWOLR, and after the model is formed, the classification accuracy will be calculated. The results of this study indicate that mapping gender inequality in Indonesia based on influencing factors using the GWOLR model forms three groups. The first mapping location labeled as low inequality is influenced by women whose birth was attended by a health worker (X1), women who have a pre-employment card (X7), women who are employed (X8), and the percentage of women who married before the age of 17 (X10). The second mapping location labeled with middle inequality is influenced by women whose delivery is attended by a health worker (X1), women's net enrolment in higher education (X2), and women married before the age of 17 (X10). The three locations categorized as high inequality are influenced by female birth attendance by health personnel (X1), Women's Human Development Index (X3), female rape offenses (X4), female domestic violence offenses (X6), and female marriage under the age of 17 (X10). Modeling the Gender Inequality Index using the GWOLR model resulted in higher classification accuracy than the ordinal logistic regression model, which was 94.11%.
MODELING OPEN UNEMPLOYMENT RATE IN KALIMANTAN ISLAND USING NONPARAMETRIC REGRESSION WITH FOURIER SERIES ESTIMATOR
Authors: Rahmania Rahmania , Sifriyani Sifriyani , Dani Andrea Tri Rian
Published: March 2024

Nonparametric regression is a regression approach that is used to determine the relationship between the response variable and the predictor variable if the shape of the regression curve is unknown. One of the popular estimators used in nonparametric regression is the Fourier series estimator. Fourier series nonparametric regression is generally used when the pattern of the investigated data is unknown and there is a tendency for the pattern to repeat. The purpose of this study is to estimate nonparametric regression using the Fourier series approach and to find out the factors that influence the open unemployment rate on the island of Borneo in 2021. The criteria for the goodness of the model used Generalized Cross Validation (GCV) and the coefficient of determination ( ). Based on the results, it was found that the best nonparametric regression model for the Fourier series was the model with 5 oscillations which indicated a minimum GCV of 10.47 and an  of 74.22%. Furthermore, based on the results of parameter significance testing either simultaneously or partially, it shows that all predictor variables have a significant effect on the open unemployment rate. The predictor variables include the labor force participation rate, the average length of schooling, the percentage of poor people, economic growth rate, and total population.
APPLICATION OF THE NEURAL NETWORK AUTOREGRESSIVE (NNAR) METHOD FOR FORECASTING THE VALUE OF OIL AND GAS EXPORTS IN INDONESIA
Authors: Junita Tarisya Permata , Kartikasari Mujiati Dwi
Published: March 2024

Indonesia is one of the countries with the most diversity and abundant natural resources, consisting of many commodities, and has enormous trade potential with other countries The success of economic activity a country can be measured by the amount of economic growth that occurs in the country. A recession is when a country's economic condition is getting worse. Meanwhile, a recession in Indonesia is expected to occur in 2023. In a 2022 news issue written by the editorial team, tirto.id said that some experts say that if 2023 is a recession, the cause is due to a spike in inflation from the impact of the Russia-Ukraine conflict. It is known that the value of oil and gas exports affects the Indonesian economy. Any increase in the value of oil and gas exports will be followed by an increase in economic growth, and vice versa. However, over time, the value of oil and gas exports has decreased every year. Therefore, forecasting the value of oil and gas exports is needed so that the country's economic sector development strategy can be on target. In addition, oil and gas export forecasting is also needed to determine the distribution of goods exports that must be carried out. In this study, we forecast the value of oil and gas exports using the neural network autoregressive (NNAR) method. The choice of this method is made because there is no assumption of normality of the residuals and white noise like in autoregressive models. From the NNAR method, the best model results are obtained, namely NNAR (2,3) with a MAPE value of 11.75640%, which means that this model has very good forecasting performance.
NUMERICAL MODELING OF THE 1998 PAPUA NEW GUINEA TSUNAMI USING THE COMCOT

Published: March 2024

The Papua New Guinea tsunami of 1998 is a unique phenomenon because the source of the tsunami propagation has been speculated. There was a 7.1-magnitude earthquake on July 17, 1998, at 18:49 WIT before the tsunami hit the Aitape area. However, previous studies have shown that the leading cause of the tsunami was not the earthquake but a submarine landslide. One of the steps to simulating the event is to do tsunami modeling. A tsunami propagation simulation will be conducted using Cornell Multi-grid Coupled Tsunami (COMCOT). This simulation was carried out with three scenarios to see which had the most significant effect on the tsunami event. The first scenario uses a tsunami source from a 7.1 magnitude earthquake, the following scenario is carried out using avalanche parameters, and the last scenario is a scenario with a combined source of earthquake and avalanche. The results of this study indicate that underwater landslides are the source of a tsunami similar to the original event.

Dengue hemorrhagic fever (DHF) is an acute febrile illness caused by a virus through the Aedes mosquito. North Sumatra is among the three provinces with the highest incidence and mortality rates in Indonesia. Mapping of DHF cases is very important in efforts to control and prevent the disease. The Partitioning Around Medoid (PAM) algorithm is commonly used to cluster DHF cases. The idea of PAM is a clustering algorithm with a similarity-based approach to grouping objects in one cluster. There are two main focuses in the research: mapping regencies/cities based on dengue case information and analyzing the performance of several similarity functions. The dataset includes variables of incidence rate (IR), case fatality rate (CFR), larva-free rate (ABJ), and population, obtained from the North Sumatra Provincial Health Office and the Central Statistics Agency (BPS). The analysis showed that three clusters were formed in North Sumatra Province. The first cluster includes regencies/cities such as Langkat, Deli Serdang, Karo, Simalungun, Dairi, Samosir, Humbahas, North Labuhan Batu, North Padang Lawas, South Labuhan Batu, Padang Sidempuan, Nias, South Nias, North Nias, and Sibolga. The second cluster consists of regencies/cities such as Medan, Binjai, Sedang Berdagai, Tebing Tinggi, Batubara, Asahan, Tanjung Balai, Labuhan Batu, Toba, North Tapanuli, Central Tapanuli, Gunungsitoli, and West Nias. The third cluster includes the regencies of South Tapanuli and Mandailing Natal. In addition, an evaluation was conducted using the Silhouette Index to measure the quality of the clustering. Based on the comparison using distance methods (Euclidean distance, Manhattan distance, Minkowski distance, and Chebyshev distance), the highest Silhouette Index value was obtained using Chebyshev distance, which amounted to 0.527554. This value indicates reasonable cluster quality. Thus, this study contributes to the mapping of DHF cases in North Sumatra Province and can be the basis for decision-making in overcoming the disease.

Rainfall forecasting is crucial in agriculture, water resource management, urban planning, and disaster preparation. Traditional approaches fail to capture complicated and intermittent rainfall patterns. The “Hybrid Exponential Smoothing Neural Network” is introduced in this study to handle intermittent rainfall forecasting issues. Exponential Smoothing, an established approach for discovering underlying patterns and seasonal fluctuations in time series data, is combined with Neural Networks, which are good at capturing complex linkages and nonlinearities. Using these two methods, this model hopes to deliver a complete rainfall forecasting solution that accounts for short-term changes and long-term patterns. This research uses residuals from the exponential smoothing model and is modeled using a Neural Network. The residual input is transformed using rolling mean. The results show that the hybrid model is able to capture patterns well, but there are still patterns that experience time lag. Experimental results obtained reveal that the hybrid methodology performs better than the model exponential smoothing, implying that the proposed model hybrid synergy approach can be used as an alternative solution to the rainfall time series forecasting. The results show that the Hybrid method can form patterns better than individual exponential smoothing models or neural networks. The RMSSE values for all areas are 1.0185, 1.55092, 1.0872.

Teknik uji validitas data yang digunakan yaitu triangulasi sumber data dan triangulasi metode. Hasil penelitian ini adalah sebagai berikut: Pertama, penggambaran hubungan alam dan manusia sesuai dengan teori Lawrence Buell pada antologi puisi Kekasih Teluk disebut dengan topofolia. Kedua, pada antologi puisi ini keempat bentuk ekokritik menurut teori Lawrence Buell yang ditemukan yaitu historikal elemen nonmanusia, legitimasi kepentingan elemen nonmanusia terhadap kepentingan manusia, dinamisasi alam, dan pertanggungjawaban manusia terhadap alam. Ketiga, antologi puisi Kekasih Teluk selaras dengan materi puisi di kelas 10 atau fase E Kurikulum Merdeka, sehingga dapat dimanfaatkan sebagai alternatif materi ajar oleh guru. Analisis ekokritik berdasarkan hasil penelitian dapat menjadi langkah alternatif memahami makna puisi secara mendalam. Hal tersebut selaras dengan cara mamahami makna puisi secara mendalam adalah dengan menganalisis diksi-diksi tertentu, suasana, dan tema.
