Each of Prosopis Africana pod extract (PAPE) and Citrulluslanatus (WMPE) performed quite well as green inhibitors in the electrochemical corrosion in acidic solution at ambient temperature in previous research. However, the hybridization of these compounds was varied with the concentration ratio in this study to optimize the efficiency of the green inhibitor in a hydrochloric acid medium using mild steel. The extraction process of the inhibitor samples was carried out with the Soxhlet apparatus using n-hexane as the solvent. Furthermore, the potential inhibition efficiency was monitored using various corrosion measurement techniques at room temperature. The inhibitive response of the extracts could be attributed to the adsorption of the extracts’ components on mild steel surface by physisorption mechanism according to the Langmuir adsorption isotherm model. The results revealed that inhibition efficiency (IE%) depends on the concentration of the extracts. The peak IE% values were obtained with a hybrid ratio of 3:1 (PAPE: WMPE) for gravimetric technique. The Tafel polarization and gasometrical measurement technique is 96.7%, 98.5% and 83.1% respectively at the concentration of 1.0 g/L, which are above the peak IE% for PAPE (93.7%, 80.96% and 77.8%) and WMPE (92.7%, 80.5% and 75.6%).

Analisis Pola Asuh Orang Tua Terhdap Anak Yang Mengalami Kekerasan Dalam Rumah Tangga (KDRT)
Authors: Putri Diana  , Arista Candra Irawati  
Published: May 2023

Parenting style has a very important role in preventing violence against children. Domestic violence is very close to children's lives. Violence that is often carried out in the household will affect children. Children who live in families who experience domestic violence have a higher risk of experiencing neglect, becoming victims of direct abuse and also have the risk of losing parents. There are four forms of domestic violence that are often perpetrated by parents against children, namely: physical violence, psychological violence, sexual violence and household neglect. This parenting style has a major impact on the moral ethics of children. Incorrect choice of parenting style can actually have several impacts on children, such as not being able to make decisions, not being good at building social relationships, disrupting physical development, having unstable emotions, and being more likely to disobey parents.
Abstrak
Pola asuh mempunyai peran yang sangat penting dalam tindakan pencegahan kekerasan terhadap anak. Kekerasan dalam rumah tangga sangatlah dekat dengan kehidupan anak, Kekerasan yang sering di lakukan didalam rumah tangga akan berpengaruh pada anak-anak. Anak-anak yang tinggal dalam lingkup keluarga yang mengalami kekerasan dalam rumah tangga memiliki risiko yang lebih tinggi untuk mengalami penelantaran, menjadi korban penganiayaan langsung dan juga memiliki resiko untuk kehilangan orang tua. Bentuk kekerasan dalam rumah tangga yang sering di lakukan orang tua terhadap anak ada empat bentuk kekerasan yaitu: kekerasan fisik, kekerasan psikis, kekerasan seksual dan penelantaran rumah tangga. Pola asuh tersebut berdampak besar pada etika moral anak. Salah pemilihan pola asuh nyatanya dapat membuat beberapa dampak pada anak, seperti tidak dapat membuat keputusan, kurang pintar dalam membangun hubungan sosial, gangguan pada perkembangan fisik, memiliki emosi yang kurang stabil, hingga lebih sering membangkang pada orangtua.
Metode Pemahaman Hadis Tata Cara Salat Masa Pandemi Menurut Imam Syafi’i
Authors: Fatihunnada  , Rofiatul Uzma  , Sahabuddin S  
Published: May 2023

Dewasa ini virus corona (covid-19) telah tersebar di Negara kita, wabah virus ini sangatlah berbahaya bahkan bisa mengakibatkan kematian. Pemerintah Negara pun sudah menghimbau kepada masyarakat untuk mematuhi protokol kesehatan yang sudah disosialisasikan agar dapat meminimalisir angka penyebaran virus corona. Namun dalam waktu dekat ini muncul pertanyaan dari sebagian masyarakat terkait hukum melaksanakan salat jum’at dan salat lima waktu berjamaah di masjid dengan menerapkan protokol kesehatan (seperti merenggangkan shaf salat karna adanya physical distancing), hukum memakai masker ketika salat, dan tata cara melaksanakan salat jum’at karena akibat physical distancing menjadi sangat terbatas kapasitas berjamaah dalam masjid.
Metode yang digunakan dalam penelitian ini yaitu metode analisis terkait pemahaman hadis-hadis mukhtalif menurut Imam Syafi’i tentang hadis perintah merapatkan shaf dan hadis larangan menutup mulut ketika salat.
Hasil penelitian ini menunjukkan bahwa hadis tentang perintah merapatkan shaf, berdasarkan sabda Nabi Saw: “Luruskanlah shaf kalian, karena lurusnya shaf adalah bagian dari ditegakkannya salat.” Metode Imam Syafi’i dalam teori ilmu hadis mukhtalif perintah dan larangan yaitu dengan membandingan satu riwayat hadis dengan riwayat lainnya dan pendekatan melalui teori bahasa. Maka hasil dari hukum merapatkan shaf adalah sunnah. Sedangkan hadis tentang larangan menutup mulut ketika salat, Nabi Saw, bersabda: “Bahwasanya Nabi Saw, melarang menjulurkan pakaian dalam salat dan melarang seseorang menutupi mulutnya ketika salat.” Hal ini menurut Imam Syafi’i boleh menutup mulut ketika salat, karena menggunakan masker ketika salat itu tidak menjadi penghalang sujud, karena menurutnya hidung tidak termasuk rukun sujud, dan di sisi lain adanya pandemi corona menjadi udzur syar’i karena dapat membahayakan kesehatan.

Abstract
Far-UV light sources have attracted much attention for human-safe viral inactivation and bacterial disinfection. Due to large optical nonlinearity and transparency to this wavelength region, AlN is a promising material for compact and low-cost far-UV second harmonic generation (SHG) devices. In this study, a transverse quasi-phase-matched AlN channel waveguide with vertical polarity inversion was designed and fabricated. From wavelength spectra and a pump power dependence of an SH intensity, far-UV SHG via the largest nonlinear optical tensor component d
33 was successfully confirmed under ultrashort pulse laser excitation.

A Review of AIoT-based Edge Devices and Lightweight Deployment
Authors: Sun Kailai , Wang Xinwei , Zhao Qianchuan 
Published: May 2023

<p>Artificial Intelligence of Things (AIoT) which integrates artificial intelligence (AI) and the Internet of Things (IoT), has attracted increasing attention recently. With the remarkable development of AI, deep neural networks (DNNs) have achieved great success from research to deployment in many applications. However, deploying complex and state-of-the-art (SOTA) AI models on edge applications is increasingly a big challenge. This paper focuses on the convergence of AIoT-based edge devices, lightweight DNNs, and neural network compression. We provide a comprehensive analysis of them and many practical suggestions for researchers: how to obtain/design lightweight DNNs, how to select suitable AI edge devices, and how to compress and deploy them in practice. Finally, future trends and opportunities are presented, including trustworthy AI, federated learning, and robust deployment. </p>
Coverage Analysis of IRS-Aided Millimeter-Wave Networks: A Practical Approach
Authors: Etcibasi Abdullah , Aktas Emre 
Published: May 2023

<p>Intelligent reflecting surfaces (IRSs) have become a popular topic in recent years for their great potential for controlling the radio link environment of wireless networks. With this controlled environment, the coverage can be increased. This paper examines the coverage analysis of IRS-aided networks, considering both two-dimensional buildings and the product-distance path loss model for the first time. Leveraging the tools from stochastic geometry, the locations of base stations (BSs), buildings, and IRSs are modeled with a homogeneous Poisson point process (PPP). A Gamma approximation for the distribution of the nearest line-of-sight (LoS)-neighbor distance is proposed, leading to a closed-form expression for the distribution of the product-distance. Feasible BSs are defined as BSs which are reachable via an IRS deployed on a specific facade of a building, and the ratio of feasible BSs is derived. Simulations are performed, which confirm the proposed analytical methods. In the numerical results, it is observed that the IRSs can introduce up to a 45\% coverage boost, and the effect of the IRS length on the coverage probability is limited beyond 1.2 meters at 60 GHz.</p>
An Improved Technique to Synthesize the Radiation Pattern of the Antenna Arrays
Authors: Vergholami Hafez 
Published: May 2023

<p> This article presents an improved antenna array pattern synthesis method, which can be effectively applied to synthesize of the radiation pattern of arbitrary linear and planar arrays with equal space between the array elements. In mathematics theory, method of the least squares is a routine way to discover the best fit curve to the specified data. Least square method (LSM) with Richardson technique will be a more direct technique to synthesize the radiation pattern of any linear and planar, equally spaced antenna arrays. The goal of them is to find the amplitude of each element of the under-studying array. Simulation results demonstrate that pattern synthesis of linear antenna arrays using the proposed method, provides considerable enhancements compared to the other ones. </p>
Layered Soil Remote Sensing with Multi-Channel Passive Microwave Observations and Physics Driven Artificial Intelligence: A Theoretical Study
Authors: Bai Xuyang , Tan Shurun 
Published: May 2023

<p>The vertical distribution of soil properties is crucial in accurately representing various environmental processes such as freeze-thaw cycles and diurnal variations. In this paper, considering the complexity of the multi-parameter features of layered soil, we evaluate the potential to retrieve the vertical distribution of the moisture and temperature of soil using multi-channel passive microwave observations. To enhance the inversion rate and accuracy, a novel Physics-Driven Artificial Neural Network (P-ANN) inversion algorithm combining multi-angle (30 to 50 degree), multi-frequency (L-, C-, and X-band), and multi-polarization (horizontal and vertical polarization) passive observations is proposed. In this approach, the multi-channel physical brightness temperature simulations corresponding to the predicted soil state parameters are integrated into the loss function of a standard fully connected neural network, enabling efficient convergence with limited sampling data in the training process. Testing results exhibit that the inversion performance of P-ANN is superior than that of conventional neural network approaches which only adopts errors in soil states in the loss function to train the network. Test also shows the proposed P-ANN approach outperforms traditional optimization algorithms in dealing with layered soil retrieval. In order to further improve the retrieval accuracy, an advanced local optimization scheme is also proposed, where the output from P-ANN is further treated as the initial value to a local optimization algorithm, achieving even closer results to the true values without excessive computational resources. In addition, to estimate the reliability of the model predictions, this paper also establishes a statistical relationship between the soil inversion error and the error of corresponding brightness temperatures from the testing process. </p>
<p>When the trained neural network is in operation, the error of brightness temperature is calculated through the physical model, and the reliability of retrieval soil results is then acquired by putting the calculated brightness temperature errors into the pre-established statistical relationship. The proposed concepts and approaches have demonstrated the feasibility of using P-ANN model with multidimensional observations to invert the layered soil structure. The proposed approach holds great potentials for various remote sensing applications as well as a wide range of inverse problem challenges.</p>
Improving Sit/Stand Loading Symmetry and Timing Through Unified Variable Impedance Control of a Powered Knee-Ankle Prosthesis
Authors: Welker Cara , Best T. Kevin , Gregg Robert 
Published: May 2023

<p>Individuals using passive prostheses typically rely heavily on their biological limb to complete sitting and standing tasks, leading to slower completion times and increased rates of osteoarthritis and lower back pain. Powered prostheses can address these challenges, but have control methods that divide sit-stand transitions into discrete phases, limiting user synchronization across the motion and requiring long manual tuning times. This paper extends our preliminary work using a thigh-based phase variable to parameterize optimized data-driven impedance parameter trajectories for sitting, standing, and walking, with only two classification modes. We decouple the stand-to-sit and sit-to-stand equilibrium angles through a knee velocity-dependent scaling term, reducing the model fitting error by approximately half compared to our previous results. We then experimentally validate the controller with three individuals with above-knee amputation performing sitting and standing transitions to/from three different chair heights. We show that our controller implemented on a powered knee-ankle prosthesis produced biomimetic joint mechanics, resulting in significantly reduced sit/stand loading asymmetry and time to complete a 5x sit-to-stand task compared to participants' passive prostheses. Integration with a previously developed walking controller also allowed sit/walk transitions between different chair heights. The controller's biomimetic assistance may reduce the overreliance on the biological limb caused by inadequate passive prostheses, helping improve mobility for people with above-knee amputations. </p>
