Criteria for entanglement and separability of discrete quantum states
Authors: Wang Miao , Cao Zhenfu , Dong Xiaolei
Published: June 2023

Entanglement is an important quantum resource, which can be used in quantum teleportation and quantum computation. How to judge and measure entanglement or separability has become a basic problem in quantum information theory. In this paper, by analyzing the properties of generalized ring $\mathbb{Z}[i]^{{2}^{n}}$, a new method is presented to judge the entanglement or separability of any quantum state in the discrete quantum computing model proposed by Gatti and Lacalle. Different from previous criteria based on matrices, it is relatively simple to operate in mathematical calculation. And if a quantum state is separable, it can calculate the separable mathematical expression. Taking $n=2,3$ as examples, the concrete forms of all separable states in the model are presented. It provides a new research perspective for the discrete quantum computing model.
Site recurrence for continuous-time open quantum walks on the line
Authors: Loebens Newton
Published: June 2023

In recent years, several properties and recurrence criteria of discrete-time open quantum walks (OQWs) have been presented. Recently, Pellegrini introduced continuous-time open quantum walks (CTOQWs) as continuous-time natural limits of discrete-time OQWs. In this work, we study semifinite CTOQWs and some of their basic properties concerning statistics, such as transition probabilities and site recurrence. The notion of SJK-recurrence for CTOQWs is introduced, and it is shown to be equivalent to the traditional concept of recurrence. This statistic arises from the definition of $\delta$-skeleton of CTOQWs, which is a dynamic that allows us to obtain a discrete-time OQW in terms of a CTOQW. We present a complete criterion for site recurrence in the case of CTOQW induced by a coin of finite dimension with a set of vertices $\mathbb{Z}$ such that its auxiliary Lindblad operator has a single stationary state. Finally, we present a similar criterion that completes the case in which the internal degree of freedom of each site is of dimension 2.

Epoxide-functionalization has emerged as an effective strategy for enhancing the oxidative stability of poly(ethylenimine)-based CO2 capture sorbents. However, the underlying mechanism remains largely unexplored. Here we combine first-principles modeling, material synthesis, and characterizations to investigate the impact of epoxide-functionalization on hydrogen bonding and mobility in poly(ethylenimine) (PEI). Blue-moon ensemble and deep potential molecular dynamics simulations reveal that epoxide-functionalization leads to stronger hydrogen bonding involving hydroxyl groups. Synthesized branched PEI samples with and without propylene-oxide (PO) functionalization are characterized using DSC, NMR relaxometry, and fluorescent probes, demonstrating that PO-functionalization significantly reduces BPEI mobility. These findings suggest that the enhanced oxidative stability of epoxide-functionalized PEI can be attributed to the formation of strong hydrogen bonds with hydroxyl groups, which restrict the mobility of PEI and decelerate mobility-dependent radical propagation reactions responsible for polymer degradation. Strategies for further tuning hydrogen bond environment are proposed based on these findings.

The ability to molecularly engineer luminescent metal-organic frameworks is a powerful tool for the design of better performing rational temperature sensors. Lanthanide based MOF stand out as luminescent temperature sensors due to the high luminescence intensity and sharp emission lines of the lanthanides. The use of two different lanthanide cations incorporated into the same MOF structure is supposed to allow for a rational, that is self-referencing, temperature sensing. Here, we present series of mixed EuxTb(1-x)BTC, which were designed as nanoparticles. The EuxTb(1-x)BTC series shows controllable luminescent properties, which depend on the solvation of the lanthanide. The two MOFs in the series with the lowest Eu content, i.e. Eu0.04Tb0.96BTC and Eu0.02Tb0.98BTC, are suitable candidates for rational temperature sensing in the range between 200 and 270 K and above 300 K.

Knee osteoarthritis is a degenerative joint disease affecting millions worldwide. Early detection and monitoring of knee osteoarthritis are critical for effective management of the disease. Magnetic resonance imaging (MRI) is a powerful tool for detecting knee osteoarthritis, but the interpretation of MRI images can be prolonged and subjective. In this paper, we propose a deep learning-based approach for the automatic diagnosis of knee osteoarthritis from MRI images. Our approach involves a deep learning architecture known as Dense Net, which has shown promising results in image classification tasks. We also incorporate a Squeeze-and- Excitation (SE) layer into the network, which can selectively emphasize informative features in the input images. We train and validate our approach using the OAI dataset of MRI images from patients with knee osteoarthritis and healthy controls. The images will then be fed into the Dense Net with SE layers to automatically classify them as either healthy or osteoarthritis. The python script generates a sample report for the MRI scans uploaded in the portal. The patient should be able to access their report but should also be able to generate a report if they have their MRI scans. The proposed model with Dense Net architecture gives an accuracy of 88.5%. The performance of our approach will be evaluated using various metrics such as accuracy, precision, recall, F1 score, confusion matrix, and area under the receiver operating characteristic curve (AUC-ROC).

CONHECIMENTOS PRÉVIOS SOBRE CALOR E TEMPERATURA A LUZ DA APRENDIZAGEM SIGNIFICATIVA CRÍTICA NO CONTEXTO DOS ANOS INICIAIS
Authors: Magalhães Arthur Philipe Cândido de , Villagrá Jesús Ángel Meneses , Greca Ileana Maria , Rizzatti Ivanise Maria
Published: June 2023

Este trabalho tem como finalidade descrever e interpretar características das concepções prévias de 18 estudantes do 4º ano do Ensino Fundamental, no contexto dos anos iniciais acerca dos conceitos de calor e temperatura. Para esta pesquisa utilizou-se uma abordagem qualitativa com objetivo descritivo, adotando o estudo de caso como procedimento. Como instrumentos de coleta de dados, teve-se a elaboração de um mapa mental, uma entrevista semiestruturada e uma roda de conversa. O diagnóstico revela que os alunos tem suas ideias prévias essencialmente de origem sensorial, o que implica em não diferenciar os conceitos de calor e temperatura, associação do calor somente as altas temperaturas, como uma substância, uma espécie de fluido, que pertence a um corpo e pode penetrar em outros. Ademais, a temperatura é apresentada com duas dimensões, frio e quente ou como oposto ao calor, mas identificam o termômetro como instrumento para verificar a temperatura. Os resultados possibilitam estruturar uma sequência de estudos, que não será objeto de análise neste artigo, que leve em consideração o que os estudantes sabem e faça-os avançar para uma perspectiva mais científica dos conceitos.

COMPREENSÕES SOBRE A NATUREZA DA CIÊNCIA NAS DIRETRIZES CURRICULARES NACIONAIS PARA OS CURSOS DE CIÊNCIAS BIOLÓGICAS
Authors: Custódio Otávio da Silva , Custódio Renato da Silva
Published: June 2023

Nota-se a escassez de pesquisas que indagam que concepções acerca da atividade científica são difundidas pelas Diretrizes Curriculares Nacionais (DCNs) para os cursos de Ciências Biológicas, ainda que essas diretrizes balizem a estrutura e os objetivos de tais cursos e, consequentemente, a formação de graduandos. Neste sentido, esta investigação objetiva identificar e analisar compreensões que as DCNs para os cursos de Biologia, detalhadas pelo Parecer 1.301/2001, detêm sobre a Natureza da Ciência. Como resultado, obtido através de uma análise de conteúdo, emergiram quatro categorias. Duas delas correspondem a compreensões mais deformadas sobre a prática científica, sendo elas: algo de uma visão empírico-indutivista, ao passo que o documento não alude à importância de hipóteses/teorias apriorísticas de pesquisadores e a relação dessas com processos experimentais; e, algo de um método científico, uma vez que o documento dá a entender que a Ciência é construída por meio de uma sequência linear de etapas a serem seguidas rigidamente. As outras duas categorias, por sua vez, refletem sobre aspectos consensuais acerca do que seriam compreensões mais adequadas da atividade científica, sendo elas: a que envolve a necessidade indicada pelo parecer de se abordar questões históricas e epistemológicas das Ciências Biológicas quando em seus cursos de graduação; e, a que apresenta a importância de se estreitar a relação entre Biologia e processos educativos. Por fim, destaca-se a importância da análise de compreensões sobre a Natureza da Ciência, exteriorizadas por legislações que orientam processos formativos.

Enactment of NZEB by state of art techniques in sultanate of oman
Authors: Ninzo Thomas , Mohammed Junaid Mouda , Ch. Venkateswara Rao
Published: June 2023

The Sultanate of Oman, being a petroleum-producing country, depends on fossil fuels for the majority of its power production. The fossil fuel sources are on the verge of extinction if they are used at the current rate. Globally, buildings are expected to generate the energy they demand using renewable energy sources and, if possible, feed it to the grid. Zero Energy Buildings (ZEBs) and Near Zero Energy Buildings (NZEBs) are put into action for the above purposes. With an average global solar irradiation of 5.56 kWh/m2/day and an average wind speed of 6.58 knots, solar and wind are the primary renewable energy sources that can be yoked in Oman. The solar and wind power plants that are being built in Oman are following the Grid Code Operations as of 2020. Buildings in Oman, newer ones and old ones, are constructed using traditional building materials, leading to poor performance of the building's peripheral enclosure and little or no emphasis on sustainability. This has led to thermally bungling building envelopes in Oman, contributing to high energy consumption for lighting and cooling buildings, which invariably adds to global warming. Extensive use of fossil fuels has also escalated the average global surface temperature. The main aim of this paper is to analyze the design and development of ZEB/NZEB technology to be used in an educational institute in Salalah, Sultanate of Oman, incorporating state-of-the-art techniques in harnessing renewable energy sources with Battery Storage Systems (BSS), construction/modification and orientation of buildings towards energy-efficient buildings, smart and energy-efficient systems and appliances, HVAC approaches, and automated real-time conservation practices using Internet of Energy (IoE).

Authors: Sri Ram Deepak Akella , Reddy Bala Sai Sunder Naidu , Abbireddi Vinay Charan Reddy
Published: June 2023

The Tesla valve is appealing for drift control and rectification in mini and microfluidic applications due to its passive operation and no-shifting-elements design. The effectiveness of such valves may be increased through their in-series association. In this study, a new Tesla-type valve is effectively designed to improve the amount of heat transfer by facilitating circulation. The Tesla valve is a one-way valve without a moving component that lets the fluid flow effortlessly in a single direction, but presents a very high impedance in the opposite direction. The present study deals with a numerical analysis of the Tesla valve design for the optimal amount of heat transfer. For this purpose, the Taguchi layout optimization approach is considered for the simulation by creating a Design of Experiments (DOE) array. The factors considered are heat flux, velocity, and type of flow, with three levels each. The design is done in SOLIDWORKS, and the simulation is performed in Analysis of Systems (ANSYS). The inlet temperature of the fluid is 22.75 °C, and water is considered the working fluid. The result of the simulation shows that the design with an inlet velocity of 0.25 m/sec and a backward flow type provides the highest heat input of 45000 W/m2.

Published: June 2023

One of the most significant classes of engineering materials in the modern period is Metal Matrix Composites(MMCs). In recent years, MMCs have attracted a lot of attention. MMCs are displacing traditional metallic materials in the automobile and aerospace industries owing to their numerous advantageous characteristics, which include low weight, high specific strength, good wear resistance, enhanced resistance to creep, etc. MMCs aid in improving the functionality of industrial parts without adding extra weight to the system. Despite the fact that several distinct types of MMCs have been created over the years, aluminum and magnesium MMCs have emerged as the most promising materials in the aerospace and automotive fields due to their improved tribological performance, low weight, and excellent mechanical properties. However, there are a number of factors that are divided into three categories that affect the tribological behavior of these MMCs, including the reinforcement material (volume fraction, reinforcement type, shape), the operating conditions (sliding speed, normal load), and the environmental conditions (relative humidity and temperature). This study seeks to give a thorough review of the history, categorization, materials, and applications in many fields, as well as the distinct tribological and corrosion behavior of the Al/Mg MMCs under various situations. To pave the way for future researchers working in these sectors, it also outlines the methods and properties used in the study.

Barang elektronik adalah salah satu jenis barang yang banyak diperjualbelikan masyarakat, seperti secara online. Namun, jual beli barang elektronik secara online mempunyai risiko yang besar, yaitu risiko kerusakan pada saat pengiriman. Guna mengatasi risiko tersebut, salah satu kebijakan yang dilakukan oleh Tokopedia yaitu mewajibkan adanya asuransi. Padahal dalam Hukum Islam, asuransi tidak termasuk menjadi rukun dan syarat jual beli.Oleh karena itu, penting untuk menjawab bagaimana hukum dan perspektif maslahah mursalah terhadap asuransi yang menjadi syarat dalam jual beli barang elektronik di Tokopedia. Penelitian ini merupakan penelitian hukum empiris dengan pendekatan kualitatif. Hasil penelitian menunjukkan bahwa adanya syarat asuransi dalam jual beli barang elektronik yang ditetapkan oleh Tokopedia tidak bertentangan dengan Hukum Islam dan jual beli dengan syarat tersebut dibolehkan selama rukun dan syaratnyaterpenuhi. Kemudian perspektif maslahah mursalah mengenai asuransi sebagai syarat dalam jual beli barang elektronik di Tokopedia yaitu asuransi ini termasuk maslahah hajiyah (kebutuhan sekunder). Kemaslahatan tersebut keberadaannya sangat diperlukan untuk menghilangkan kesulitan yang dapat mengakibatkan hilangnya sesuatu yang dibutuhkan, tetapi tidak sampai merusak kemaslahatan umum. Dengan demikian, asuransidalam jual beli barang elektronik ini dapat mendatangkan manfaat dan menjauhi keburukan sesuai dengan teori maslahah mursalah.

Published: June 2023

The purpose of this study is to reveal the factors and solutions to the stagnation of Islamic banking. Data were gathered for this qualitative study through observation, interviews, and documentation studies. The study's findings demonstrate that the growth of Islamic banks has slowed, as evidenced by their low market share, declining financing deposit ratio, and declining return on assets. The expansion of the Islamic Banking staff network and offices has also slowed down. Islamic banking's initial reasons for stagnation include its subpar performance in carrying out social tasks, specifically the collecting and distribution of cash. The second requirement is the capacity to apply Sharia principles to every banking activity. The three Arabic term labels on the goods offered by Islamic Banking continue to cause confusion in the community. Fourth, judicial disputes unrelated to banking include entities and people associated with Sharia designations, which have an effect on public confidence. This research provides input to Islamic banks to prioritize social functions, the collection and distribution of zakat, infaq, alms; apply sharia principles; Indonesianize arabic terms.

Authors: Doğan Halit , Mutlu Yılmaz
Published: June 2023

In this study, AA2024 aluminum alloy was selected as the matrix material, while B4C was selected as the reinforcement material, and particle-reinforced Al-matrix composite materials were produced using the powder metallurgy method. Examinations were made to determine the effects of different reinforcement particle ratios and sintering temperatures on the mechanical properties of the AA2024 matrix composite materials that were produced. The powders were compressed in a metal mold at room temperature and a pressure of 525 MPa under a uniaxial press. The raw specimens that were obtained were sintered for 45 minutes at different temperatures. The produced composite materials were subjected to three-point bending tests and hardness measurements. Optical microscopy analysis was carried out for characterization. The results allowed us to draw a conclusion on how the reinforcement material in the produced specimens affected Al-matrix composite properties. It was determined that the B4C reinforcement added to the matrix increased the hardness values of the composites at all sintering temperatures, the highest bending strength was obtained in the composite with 10% B4C particle reinforcement, and in general, the B4C reinforcement was homogeneously dispersed in the matrix. Increased B4C reinforcement ratios resulted in higher hardness values in the composite materials.

Published: June 2023

Object Relations (OR) has been identified as one of the four major schools of psychoanalysis. This article provides a comprehensive review of OR practice and theory in the context of rehabilitation psychology. Extensive data are presented on five of the most prominent pioneer object relations theorists, including Melanie Klein, W. R. D. Fairbairn, Michal Balint, Harry Guntrip, and D. W. Winnicott. All of these individuals have contributed significantly to object relations theory. Melanie Klein and W. R. D Fairbairn have been credited with founding the object relations perspective, Michael Balint has been touted as the leading object relations theorist, Harry Guntrip was analyzed by both Fairbairn and Winnicott, and D.W. Winnicott is probably the most creative and respected psychoanalytic theorist since Sigmund Freud. All five of these theorists brought a fresh, new perspective on psychoanalytic theory and practice, and their contributions may be used to better understand the personality development of persons with a disability and to inform the practice of rehabilitation psychology.

Published: June 2023

Cosmetics are one of the women's basic needs, but several cosmetic products on the market use synthetic dyes such as Rhodamine B, which cause various risks dangerous to health. Natural dyes are non-toxic, renewable, and environmentally friendly, one of which is anthocyanins found in dragon fruit peel. Blush-on is a cosmetic containing a dye that women often use. This study aimed to determine that the dragon fruit peel ethanolic extract can be used as a natural dye in blush-on compact powder preparations with good physical quality. Blush-on was made with various concentrations of dragon fruit peel ethanol extract of 20% (F1), 25% (F2), and 30% (F3). The preparations were observed for organoleptic and homogeneity, pH value, friability, and hedonic test during four weeks of storage, with descriptive data analysis. The results showed that dragon fruit peel extract blush-on did not meet some of the physical quality test requirements for blush-on. It is because the color of the blush-on should be red. However, the color of the preparation is white to brownish, and the preparation is also fragile. The preparation meets the requirements of homogeneity and pH value according to the physiological pH of the skin. It remains stable for four weeks of storage. F1 is the most preferred by panelists based on a preference test for the preparation's shape, color, and odor. Dragon fruit peel extract blush-on has not yet fulfilled its function as a decorative cosmetic to give color to the skin
Systematic Literature Review: Multiple-tier Diagnostic Instruments in Measuring Student Chemistry Misconceptions
Authors: Damsi Muthmainnah , Suyanto Slamet
Published: June 2023

Misconception is a conception of someone who is not by scientific concepts recognized by experts. One way to identify students' misconceptions is by conducting tests using diagnostic instruments. This study aims to identify misconceptions in chemistry learning as well as the most widely used types of multiple-tier diagnostic instruments. The research method used is a systematic literature review (SLR) by analyzing relevant research results from the Google Scholar and ERIC databases of 47 articles based on their suitability with the research theme within the last seven years (2016-2022). The systematic literature review method reviews articles systematically by following the steps that have been determined. The research findings show that students' misconceptions mostly occur in the buffer solution material with the most widely used diagnostic instrument, namely the three-tier multiple-choice (50%). The dominant cause of students' chemical misconceptions occurs due to students' internal factors in the form of a mismatch between students' preconceptions and the concepts taught by experts and strategies for applying learning models that are often used as a method to reduce students' chemical misconceptions such as the application of the Dual Situated Learning Model (DSLM) as well as implementing the Elicit, Confront, Identify, Resolve, Reinforce (ECIRR) model.
