Published: April 2022

Educational data is important information owned by a university. Large amounts of data can be used to identify specific patterns. This study aims to predict the number of new students by identifying data patterns using an artificial neural network (ANN). ANN is an artificial intelligence that has characteristics such as biological neural networks and works as an information processing system, one of the types is backpropagation model. Backpropagation trains the network to be able to recognize and identify patterns that are given during training and provide a response in the form of predicting similar patterns, therefore backpropagation can be used in the field of forecasting. Data that uses as input for the training is new student data from 2000 to 2020, and the expected output is the number of new students in the following tear, which is 2021. This study tested 4 different ANN architecture models, with MSE 0.0001, learning rate 0.01, with a maximum of 1000 iterations. The training process uses a combination of the tansig-purelin and logsig-purelin as the activation functions, and traingdx, traingda traingdm as the acceleration functions. Result of the training process, it was found that the best network architecture is the 12-8-1 pattern, which means using 12 inputs, 8 hidden neurons, and 1 output. The pattern uses the logsig-purelin activation function, the traingda acceleration function, with the MSE result of 0.0001 after going through 94 iterations. Data mahasiswa merupakan informasi penting yang dimiliki oleh suatu perguruan tinggi. Data dalam jumlah besar dapat digunakan untuk mengidentifikasi suatu pola tertentu. Penelitian ini bertujuan untuk memprediksi jumlah mahasiswa baru yang akan datang dengan mengidentifikasi pola data menggunakan Jaringan Syaraf Tiruan (JST). JST merupakan suatu kecerdasan buatan yang memiliki karakteristik seperti jaringan syaraf biologi dan berfungsi sebagai sistem pemroses informasi, salah satunya adalah model backpropagation. Backpropagation melatih jaringan agar mampu mengenali dan mengidentifikasi pola yang diberikan pada saat pelatihan dan memberikan respon berupa prediksi terhadap pola serupa, oleh karena itu backpropagation dapat digunakan dengan baik dalam bidang peramalan. Data masukan yang digunakan untuk pelatihan adalah data mahasiswa baru pada tahun 2000 sampai 2020, keluaran yang diinginkan adalah jumlah mahasiswa baru pada tahun berikutnya. Penelitian ini menguji 4 model arsitektur JST berbeda, dengan MSE 0.0001, learning rate 0.01, dengan maksimal 1000 iterasi. Proses pelatihan menggunakan kombinasi fungsi aktivasi tansig-purelin dan logsig-purelin, serta fungsi percepatan traingdx, traingda, dan traingdm. Dari pelatihan yang dilakukan, didapatkan bahwa arsitektur jaringan terbaik adalah pola 12-8-1 yang berarti menggunakan 12 masukan, 8 hidden neuron, dan 1 keluaran. Pola tersebut menggunakan fungsi aktivasi logsig-purelin, fungsi percepatan traingda, dengan hasil MSE 0.0001 setelah melalui 94 iterasi.

Es importante conocer el proceso de domesticación, dispersión y uso del maíz, como de otras plantas cultivables, así como de movilidad geográfica. Los análisis isotópicos en colágeno y bioapatita brindan la posibilidad de contrastar dietas con firmas isotópicas similares, proporcionando una base estadística confiable de diferenciación individual y poblacional sobre las fuentes de proteína específicas de origen vegetal y animal, terrestre o marina.El análisis isotópico de carbono (13C) en colágeno y bioapatita de 20 muestras obtenidas de hueso y dientes humanos procedentes de la cueva de la Sepultura 3050-2850 a. P. (1400-1100 a. C.) indica una amplia y rica variedad dietética producto no solo de cierta movilidad restringida, sino de desplazamientos en un entorno de transición ecológica entre la sierra y la costa, según atestigua el análisis de isótopos de oxígeno (18O), lo que proporciona nuevos datos al problema histórico-cultural y conceptual sobre el incremento del uso del maíz y otras plantas cultivables durante el desarrollo e interacción de los grupos cazadores-recolectores-pescadores y agricultores de baja intensidad entre el Altiplano del norte, la Sierra Madre Oriental y la Planicie costera del golfo de México en el Formativo mesoamericano.

Published: April 2022

Abstract
The short circuit (SC) capability is a crucial figure of merit for a power switching device in applications such as electrical vehicle traction inverters and chargers. SiC DMOSFETs are inferior to insulated gate bipolar transistors in terms of the SC withstand time. In this work, the SC capability of a SiC DMOSFET is investigated through non-isothermal simulations and measurements. Its sensitivity to process-induced channel length variability has been examined. Its dependence on important device design parameters has been studied, revealing the JFET width as the most sensitive amongst them for optimizing the SC capability. Previously reported SC enhancement techniques that require added fabrication steps were corroborated.
Defining persistent xenophobic behaviour in South Africa as a case of internalised colonialism
Authors: Princewill Tamunodein 
Published: April 2022

South Africa has a history of systemic racial segregation. The ramifications of this history within contemporary South Africa, that extend beyond the Black South African demographic, are yet to be fully discussed. The idea emerging is that the xenophobic culture prevalent in South Africa is a result of internalised colonialism. In discussing internalised colonialism, the notion of citizenship needs to be analysed in order to legitimise who belongs to a state and who has access to a state? The de jure factors that fortified South Africa’s apartheid regime indicate that dismantling internalised colonialism and its projection unto other Black demographics in South Africa requires legal fortification. The idea is that de facto and de jure factors can exist within a cycle that enables the deconstruction of xenophobic behaviour in South Africa. In discussing this behaviour, the larger global landscape must be considered as being part of a web that perpetuates new forms of exclusion. Emerging is an exposure of the vicious cycle that exists between previously subjugated groupings extending maltreatment towards other groupings within their spheres of influence. The idea is that a socio-totem pole exists in which there will always be an ‘other’ for the historically ‘othered’.
Black Africans’ Contributions to Global Industrial Revolutions
Authors: Uwizeyimana D.E. 
Published: April 2022

This article evaluates the contributions that have been made by Black Africans (in Africa and the diaspora) to the different industrialrevolutions. The methodology used in this research was mainly qualitative. The findings confirm that Black Africans had achieved technological advances before the arrival of Western and Eastern slave traders and colonialism in Africa, and had made substantialcontributions to the pre-industrial revolution and the first industrial revolution. Even though slavery and colonisation halted further technological innovation and advancements, there is strong evidence to suggest that Black Africans are currently contributing to theFourth Industrial Revolution. Impressive innovations are coming from Africa. African leaders must support Africans’ technological innovations through funding, proper training, and availing raw materials for them to contribute to the Fourth Industrial Revolution.
Artificial intelligence as a tool of public diplomacy
Authors: Williams Robyn , Otto Lisa 
Published: April 2022

Iran and the United States (U.S.) have had a volatile relationship for decades, with continuous threats of violence, sanctions, and internet blocks. In the last decade, we have seen a third force at play as technology becomes an integral aspect of diplomatic relations. The last three U.S. administrations have displayed mixed attempts at salvaging diplomatic relations with Iran. This article explores how artificial intelligence driven communication can be a critical tool in improving the relationship between the two states. Utilising a desktop research approach, exploring primary and secondary literature, this article explores possible artificial intelligence solutions to improve the communicational aspect in the public diplomacy between Iran and the U.S. It is evident that artificial intelligence has had negative implications on the public diplomacy between the two states as we witness the increasing use of deep-fakes and websiteblocks. However, processes such as natural language understanding allows governments to have more targeted foreign policy objectives and language translation creates a direct and enhanced line of communication between the state and foreign audience.
Beyond Sub-Imperial War, ‘Blood Methane’, and Climate-Debt Denialism
Authors: Bond Patrick 
Published: April 2022

South Africans really must confront two conjoined crises that affect both the majority here, and the vast majority next door in Mozambique. First, the climate catastrophe’s amplification due to rising dependency upon Liquefied Natural Gas (which is more than 80 times more potent than carbon dioxide in coming decades), leaving our neighbour as the world’s fourth worst-affected country since 2000, at a time when South Africa is already the third-highest greenhouse gas emitter per person/ GDP among major countries. Second, the deplorable trajectory of Pretoria’s sub-imperialist adventurism, now represented by the army’s deployment in CaboDelgado province in order to promote gas drilling by multinational corporations. In part because of the corrupt, repressive Maputo government, many Southern African civil society organisations regularly appeal for an end to both Mozambique’s ‘blood methane’ war and, behind it, the fossil fuel extraction that amplifies the climate crisis. The innovative demand is for Global-North payment of climate reparations to victims of extreme weather, plus financial compensation so as to leave the world’s fourth-largest gas ftield unexploited. Against these arguments and movements, there is a vociferous South African lobby—which can be termed ‘laptop bombardiers’—ignoring or brazenly dismissing both crises: climate and the danger of further sub-imperial mishaps. It is long overdue to confront this lobby by objecting to damaging fossil fuels and militarism, and call it to account for the vast ethical lapses in their analyses.
PENGARUH KOMBINASI GYPSUM DAN FLY ASH TIPE C PADA KUAT TEKAN MORTAR
Authors: Rahman Aulia 
Published: April 2022

The use of gypsum and fly ash is very common in construction of Indonesia. Both of these materials are used because of Indonesia's rich natural potential. Gypsum was chosen because it has the same chemical composition as cement, which is calcium (Ca), while type C fly ash also shows the same content. By combining the two materials, the researchers tried to study their impact on the compressive strength of mortar. The proportion of cement was reduced from 100%, 50%, 25%, and 0%, while the rest was replaced by a combination of gypsum and type C fly ash. Then, the samples were tested at the age of 7 and 14 days to see the compressive strength performance on early days of hardening. Samples with no substituent composition showed the highest compressive strength of 23.3 MPa, then it continued to decrease as the cement mixture became less, until the lowest was 7 MPa in samples composed only of gypsum and fly ash. There was a significant increase in performance of sample 4 which only contained 25% cement, but it was indicated that the cause was not due to composition, but other factors such as water ratio and compaction.
Keywords: gypsum, type C fly ash, mortar.
Serum adenosine deaminase activity: A novel test for early diagnosis of pulmonary tuberculosis - What about efficacy?
Authors: Irfan Muhammad , Qureshi Abdul Rasheed , Sajid Muhammad , Ashraf Zeeshan 
Published: April 2022

Background: Pulmonary tuberculosis is a tremendous public health problem, increasing significantly, especially in developing countries. Getting a TB-free globe appears to be not more than a dream. Mycobacterial culturing is the gold standard for precise diagnosis but requires six-week time, in the meantime, patients remain a source of inadvertent disease dissemination in the community. The unavailability of sputum also poses a challenge several times. As adenosine deaminase level measurement is easy, rapid and independent of a sputum sample, this study was conducted to determine the diagnostic efficacy of adenosine deaminase activity for pulmonary tuberculosis.Patients and methods: This prospective study was conducted at Pulmonology-OPD, Gulab Devi Chest Hospital, Lahore, from 01-01-2019 to 30-06-2019. A total of 300 sputum smear-positive patients with clinical and radiological evidence consistent with diagnosis of pulmonary tuberculosis and 30 normal participants without any clinical, radiological or haematological evidence of tuberculosis were included. While, smear-negative patients and those having any evidence of hepatic disease, hematopoietic malignancy, infectious mononucleosis, typhoid or pregnancy were excluded. The serum ADA level of each participant was determined. All patients were subjected to AFB culture. Diagnostic accuracy was determined by considering sputum culture as a gold standard.Results: At cut-off value of >15 IU/L, a sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of 98.30%, 100.00%, 100.00%, 85.71%, 98.46% respectively were defined. Conclusion: Serum ADA level, having excellent sensitivity and specificity, can diagnose pulmonary tuberculosis even if sputum sample is not available.
On 1-Subdivisions of Transitive Tournaments

Published: April 2022

The oriented Ramsey number $\vec{r}(H)$ for an acyclic digraph $H$ is the minimum integer $n$ such that any $n$-vertex tournament contains a copy of $H$ as a subgraph. We prove that the $1$-subdivision of the $k$-vertex transitive tournament $H_k$ satisfies $\vec{r}(H_k)= O(k^2\log\log k)$. This is tight up to multiplicative $\log\log k$-term.
We also show that if $T$ is an $n$-vertex tournament with $\Delta^+(T)-\delta^+(T)= O(n/k) - k^2$, then $T$ contains a $1$-subdivision of $\vec{K}_k$, a complete $k$-vertex digraph with all possible $k(k-1)$ arcs. This is tight up to multiplicative constant.
Computing Volumes of Adjacency Polytopes via Draconian Sequences
Authors: Davis Robert , Chen Tianran 
Published: April 2022

Adjacency polytopes appear naturally in the study of nonlinear emergent phenomena in complex networks. The ``"PQ-type" adjacency polytope, denoted $\nabla^{\mathrm{PQ}}_G$ and which is the focus of this work, encodes rich combinatorial information about power-flow solutions in sparse power networks that are studied in electric engineering. Of particular importance is the normalized volume of such an adjacency polytope, which provides an upper bound on the number of distinct power-flow solutions.
In this article we show that the problem of computing normalized volumes for $\nabla^{\mathrm{PQ}}_G$ can be rephrased as counting $D(G)$-draconian sequences where $D(G)$ is a certain bipartite graph associated to the network. We prove recurrences for all networks with connectivity at most $1$ and, for $2$-connected graphs under certain restrictions, we give recurrences for subdividing an edge and taking the join of an edge with a new vertex. Together, these recurrences imply a simple, non-recursive formula for the normalized volume of $\nabla^{\mathrm{PQ}}_G$ when $G$ is part of a large class of outerplanar graphs; we conjecture that the formula holds for all outerplanar graphs. Explicit formulas for several other (non-outerplanar) classes are given. Further, we identify several important classes of graphs $G$ which are planar but not outerplanar that are worth additional study.

AbstractIslamic religious education is an effort to educate humans in accordance with the teachings of Islam as a guide for one's life. Islamic Religious Education in reality only focuses on education organized by educational institutions or institutions from elementary to tertiary levels, but it has not touched the empirical areas faced by society such as Schizophrenia. This article uses Library Research Design. The results of the study is the number of cases that occur due to psychotic disorders has made a number of mental hospitals implement the forms of activities with the nuances of Islamic Religious Education in dealing with schizophrenia psychotic patients, such as Islamic counseling therapy, Islamic adab, Miliu therapy, interacting politely and kindly, and Islamic studies. These forms of handling have proven that Islamic Religious Education actually covers areas of medicine and health sciences, which in reality many consider Islamic Religious Education cannot touch these areas. A more in-depth study of the role of Islamic Religious Education is needed in order to make a real contribution to the problems faced by society.Keywords: Islamic Religious Education, Schizophrenia, Spiritual Development.

AbstrakPendidikan Agama Islam merupakan upaya mendidik manusia sesuai dengan ajaran agama Islam sebagai petunjuk dan pedoman hidup seseorang. Pendidikan Agama Islam pada kenyataannya hanya berkutat pada pendidikan yang diselenggarakan oleh institusi atau lembaga pendidikan dari jenjang dasar sampai perguruan tinggi, namun belum menyentuh wilayah-wilayah empirik yang dihadapi oleh masyarakat seperti Skizofrenia. Artikel ini menggunakan design penelitian kepustakaan. Hasil yang diperoleh yakni banyaknya kasus yang terjadi akibat gangguan psikotik ini membuat sejumlah rumah sakit jiwa menerapkan bentuk kegiatan yang bernuansa Pendidikan Agama Islam dalam menangani pasien psikotik skizofrenia, seperti Terapi konseling Islami, Adab Islami, Miliu terapi, berinteraksi dengan sopan dan ramah, serta Pengkajian Islami. Bentuk-bentuk penanganan tersebut telah membuktikan bahwa sebenarnya Pendidikan Agama Islam mencakup wilayah-wilayah kedokteran dan ilmu-ilmu kesehatan yang dalam kenyataannya banyak yang menilai Pendidikan Agama Islam tidak dapat menyentuh wilayah tersebut. Dibutuhkan kajian yang lebih mendalam mengenai peran Pendidikan Agama Islam agar dapat memberikan sumbangsih nyata pada problem-problem yang dihadapi oleh masyarakat.

Abstract
Two close-in planets have been recently found around the M-dwarf flare star AU Microscopii (AU Mic). These Neptune-sized planets (AU Mic b and c) seem to be located very close to the so-called “evaporation valley” in the exoplanet population, making this system an important target for studying atmospheric loss on exoplanets. This process, while mainly driven by high-energy stellar radiation, will be strongly mediated by the space environment surrounding the planets. Here we present an investigation of this last area, performing 3D numerical modeling of the quiescent stellar wind from AU Mic, as well as time-dependent simulations describing the evolution of a highly energetic coronal mass ejection (CME) event in this system. Observational constraints on the stellar magnetic field and properties of the eruption are incorporated in our models. We carry out qualitative and quantitative characterizations of the stellar wind, the emerging CMEs, as well as the expected steady and transient conditions along the orbit of both exoplanets. Our results predict extreme space weather for AU Mic and its planets. This includes sub-Alfvénic regions for the large majority of the exoplanet orbits, very high dynamic and magnetic pressure values in quiescence (varying within 102–105 times the dynamic pressure experienced by Earth), and an even harsher environment during the passage of any escaping CME associated with the frequent flaring observed in AU Mic. These space weather conditions alone pose an immense challenge for the survival of exoplanetary atmospheres (if any) in this system.
