Performance improvement of a Ag-ion controlled molecular-gap atomic switch by reducing a switching area for applying to a deep learning system
Authors: Tanimoto Naonari , Hasegawa Tsuyoshi
Published: February 2023

In today’s advanced information society, hardware-based neuromorphic systems attract much attention for achieving more efficient information processing. Hardware-based neuromorphic systems need devices that change their resistance in an analog manner like biological synapses. A molecular-gap atomic switch exhibits analog resistance change over a wider range compared to other non-volatile memory devices. However, several issues remain with the device, such as in cyclic endurance and retention. In this study, we fabricated a molecular-gap atomic switch with a reduced switching area. We expected that the reduction would limit the number of Ag+ cations that contribute to a switching phenomenon and solve the remaining issues. The fabricated devices endured 1000 switching cycles and exhibited stable analog resistance change. Deep learning was successfully demonstrated using 293 fabricated devices as synapses, which resulted in the accuracy of 93.65% in 26th epoch in a 5 × 5 pixel image classification task.
Characteristics of c-axis oriented GeAlN films and applications to higher-order mode BAW resonators
Authors: Suzuki Masashi , Sekimoto Jun , Kakio Shoji
Published: February 2023

AlN film bulk acoustic wave (BAW) resonators and filters that operate at frequencies above 5 GHz are required for 5G and beyond 5G communication applications. However, the power-handling capability, Q factor, and electromechanical coupling in high-frequency AlN film BAW resonators will be degraded as a result of the significantly reduced thickness and volume of the devices. Higher-order mode BAW resonators with polarity inverted (PI) multilayered films can operate at high frequencies while maintaining the thickness and volume of the devices. In this study, we fabricated an eight-layered PI GeAlN/AlN film BAW resonator by alternately growing Al-polar AlN layers and N-polar GeAlN layers. The PI GeAlN/AlN film BAW resonator resonated in the 8th-order mode. The film thickness of the PI GeAlN/AlN film BAW resonator was approximately thirteen times larger than that of a single-layer AlN film BAW resonator operating in the same frequency range.

We proposed an in-memory spin coupler based on the 55 nm NOR flash technology to tackle the combinatorial optimization problems. The high-density and cost-effective floating-gate (FG) devices can overcome the capacity limitation in the conventional annealing machines based on static random access memory. In addition, the FG devices featuring high endurance and excellent data retention provide more robust annealing computation as compared to resistive random access memory. A novel complementary read algorithm is further developed to increase the tolerance on threshold voltage (V
th) variation by 60%. Demonstrations show that the proposed in-memory spin coupling architecture with high efficiency and scalability has great potential for solving the combinatorial optimizations regardless of the problem size.
Improvement of extinction in optically-controlled silicon thermo-optic switch based on micro-ring resonator with distinct probe signal
Authors: Liang Zhu , Liu Shuyuan , Shoji Yuya
Published: February 2023

Herein, an optically-controlled thermo-optic switch based on a micro-ring resonator is proposed and demonstrated. The latter converts pump light to heat using a metal layer close to the waveguides to generate a phase shift based on the thermo-optic effect, thereby realizing the switching operation. By using the probe and pump lights of the transverse electric and transverse magnetic modes, respectively, optical absorption is properly designed and an extinction ratio higher than that reported in the previous study is achieved. Further, 10%–90% switching times are measured to be 0.71 μs and 2.66 μs for the rising time and cooling time of temporal response, respectively. The burst-switching measurements reveal an on/off switching ratio of 7.3 dB at the through-port and 7.2 dB at the drop port, with a pump power of 16.8 mW.

The centralised preparation of the mRNA-bnt162B2 vaccine at the Clinical Galenics Laboratory of the Hospital Pharmacy of the Mauriziano Hospital in Turin is an organisational model designed to guarantee the quality of the drug to be administered, the safety of both the vaccinee and the vaccinating personnel, and the traceability of all operations performed. The preparation in ready-for-use syringes individually packaged and labelled, according to the Good Manufacturing Practice (GMP) of the Official Pharmacopoeia, was entrusted to the Biomedical Laboratory Technician (BLT) under the responsibility of the Hospital Pharmacist. In compliance with the GMP, the model was developed through dedicated premises, specific staff training and written procedures concerning the handling of vaccines. The entire production process was guaranteed by: a Hospital Pharmacist and two interchangeable BLTs, one preparer and one assistant. They were necessary to maintain the aseptic technique and the cross-checking of all operations. Labels were prepared showing qualitative-quantitative composition, batch and expiry date, validity of the preparation, pharmacist's signature. The label applied to each syringe, together with the daily work plan, ensured traceability of the process at every stage. The efficient model proposed has always proved adaptable to the changes that characterised the vaccination campaign. From 27/12/2020 to 31/03/2022 a total of 48.017 doses were prepared. The centralisation of the vaccine preparation in the Clinical Galenics Laboratory of the Hospital Pharmacy also reduced handling errors, as well as the waste from unused residues, which proved to be only 0.08%.

Re-Label By Data Pattern Is All You Need For Knowledge Driven Deep Learning
Authors: Guo Tong
Published: February 2023

In industry deep learning application, we should fix the badcase by human evaluation after we achieve more than 95% accuracy at dev dataset. The badcase reason is from the wrong rule/knowledge of human labeling and will cause low accuracy under human evaluation. In this paper, we propose the pattern-based method to fix the badcase for industry application inference. We propose the pipeline to solve the problem and improve the accuracy of human evaluation. The experiment results verify our idea, which means label-edit is the method to implement controllable deep learning application.

Abstract: Bifacial photovoltaic modules are able to convert the solar radiation reaching their front and rear-sides, which means that more electricity can be produced using the same array area as monofacial modules with similar ratings. In some locations, the cost per power unit for such a technology has already become cost-competitive with conventional monofacial modules. The so-called effective irradiance and the bifacial gain are useful metrics, respectively, to assess the solar resource and the performance of bifacial arrays. To calculate the effective irradiance, studies previously published employ rear-side irradiance measurements, whereas to compute the bifacial gain, other works make use of monofacial modules with rating similar to those of the bifacial modules under analysis. In this paper, a straightforward method is presented, allowing to calculate the effective irradiance from the maximum power current, and to calculate the bifacial gain using a power scaling relation. The proposed method was experimentally tested using an outdoor platform with a dual-axis tracking system with bifacial modules. The effective irradiance calculated using the novel method presented nRMSE of 2.88 %, relative to the results obtained using the consolidated method. The bifacial gains obtained were 6.24 % and 6.69 %, respectively, using the proposed and traditional calculation methods. The procedure presented in this study might be useful for the quantification of the effective irradiance and the bifacial gain for PV installations which do not have extensive monitoring hardware.

Published: February 2023

This paper presents a novel optimization-based full-pose trajectory tracking method to control overactuated multi-rotor aerial vehicles with limited actuation abilities. 

The proposed method allocates feasible control inputs to track a reference trajectory, while ensuring the tracking of the reference position, and while tracking the closest feasible attitude.

The optimization simultaneously searches for a feasible trajectory and corresponding feasible control inputs from the infinite possible solutions, while ensuring smooth control inputs. The proposed real-time algorithm is tested in extensive simulation on multiple platforms with fixed and actuated propellers. The simulation experiments show the ability of the proposed approach to exploit the complex set of feasible forces and moments of overactuated platforms while allocating smooth feasible control inputs.
Relative Learning Rate Adaptation on Loss Feedback
Authors: BISWAS SAPTARSHI , DEY SUMAGNA
Published: February 2023

In the realm of Deep Learning (DL), optimization of hyperparameters like learning rate has been one of the well-known challenges. To address this problem, previous works have introduced Learning Rate Scheduling (LRS) and Adaptive Learning Rate (ALR) algorithms that used different learning rates at distinct phases of the training process to enhance the performance of DL models. But, these algorithms exhibit their own set of drawbacks. Most of the LRS techniques do not consider the learning behavior of those models while determining the learning rate. On the other hand, standard ALR algorithms such as RMSprop, Adam, and their variants optimize the training by consid- ering the local gradient patterns. However, these patterns are insufficient to determine the training efficiency when multiple local optima exist concentrated around the global optima. In this context, the proposed work introduces a new ALR method known as the Learning Rate Tuner with Relative Adaptation (LRT-RA), which decides the learning rate per training iteration based on the global loss curve. Lastly, the proposed algorithm (1) prevents a premature convergence of the training process and (2) intends to remove the cross-validation overhead to determine the precise learning rates required for the model’s training.

On the Stability and Homogeneous Ensemble of Feature Selection for Predictive Maintenance: A Classification Application to Tool Condition Monitoring in Milling
Authors: Assafo Maryam , Städter J. Philipp , Meisel Tenia , Langendörfer Peter
Published: February 2023

Feature selection (FS) represents an essential step for many machine learning-based predictive maintenance (PdM) applications, including various industrial processes, components, and monitoring tasks. The selected features not only serve as inputs to the learning models, but also can influence further decisions and analysis, e.g., sensor selection, understandability of the PdM system. Hence, before deploying the PdM system, it is crucial to examine the reproducibility and robustness of the selected features under variations in the input data. This is particularly critical for real-world datasets with a low sample-to-dimension ratio (SDR). However, to the best of our knowledge, stability of the FS methods under data variations has not been considered yet in the field of PdM. This paper addresses this issue with an application to tool condition monitoring in milling, where classifiers based on support vector machine and random forest were employed. We used a 5-fold cross-validation to evaluate three popular filter-based FS methods, namely Fisher score, minimum redundancy maximum relevance (mRMR), and ReliefF, in terms of both stability and macro-F1. Further, for each method, we investigated the impact of the homogeneous FS ensemble on both performance indicators. To gain broad insights, we used four (2:2) milling datasets obtained from our experiments and NASA’s repository, which differ in the operating conditions, sensors, SDR, number of classes, etc. For each dataset, the study was conducted for two individual sensors and their fusion. Among the conclusions: 1) Different FS methods can yield comparable macro-F1, yet considerably different FS stability values. 2) Fisher score (single and/or ensemble) is the superior in most of the cases. 3) mRMR’s stability is overall the lowest, the most variable over different settings (e.g., sensor(s), subset cardinality), and the one that benefits the most from the ensemble.

Prediction of wafer handling-induced point defects in 300 mm silicon wafer manufacturing from edge geometric data
Authors: HU HAO
Published: February 2023

Abstract- For the miniaturization of the structures of semiconductor device fabrication, high uniformity of side-flatness and edge roll-off of 300 mm wafers are required. In this study, the formation of light point defects (LPDs) on silicon (Si) wafer surface due to an edge gripper handling system was investigated. The relationships between the generation of LPDs with respect to flatness, edge profile, and edge roll-off of Si wafers were analyzed. It was found that the variation of traditionfacet parameters and near-edge geometry metric, such as edge site frontsurface-referenced least squares/range (ESFQR), have no impact on the formation of surface LPDs. By contrast, the performance of Z-height double derivative (ZDD), allowed an accurate prediction of formation of surface LPDs. Additionly, for a 300mm silicon wafer, the surface LPDs occurred with frontside ZDD obtained at a radius of 149.2 mm, ranging above -954 nm/mm2 . The surface was LPDs free when ZDD was below -1235 nm/mm2 . Surface LPD formation occurred randomly and was not predictable when ZDD ranged from -954 nm/mm2 to -1235 nm/mm2 . The result indicates that the LPDs caused by wafer handling is proportional to the performance of ZDD at the edge roll-off area of silicon wafer, this is consistent with the requirement of edge roll-off considering wafer geometry.
Artificial neural network based optimal feedforward torque control of electrically excited synchronous machines
Authors: Monzen Niklas , Hackl Christoph
Published: February 2023

An Artificial Neural Network (ANN) based Optimal Feedforward Torque Control (OFTC) strategy for electrically excited synchronous machines (EESMs) is proposed. After design, data set creation, training and validation of the ANN, the analytical computation of the optimal stator and exciter currents is achieved which allows to minimize copper and iron losses and to produce the desired (or maximally feasible) machine torque. Voltage and currents constraints of stator and exciter are considered as well. In contrast to conventional OFTC, the proposed ANN-based OFTC strategy does not require iterations nor a decision tree to find the optimal current triple while machine nonlinearities, magnetic cross-coupling, saturation and speed-dependent iron losses are taken into account. In addition, the proposed ANN design procedure allows to consider measurable OFTC goals and computational resources that ensures a real-time capable implementation. Comprehensive simulation results for a real and nonlinear EESM clearly show these benefits by comparing the proposed ANN-based OFTC with results of a nonlinear optimization problem (NLP) solver (which cannot be used in real-time). 
Shooting and bouncing rays for sparse particles (SBR-SP) applied for multiple magnetodielectric circular cylinders

Published: February 2023

A numerically efficient method of shooting and bouncing rays for sparse particles (SBR-SP) is presented to analyze a large two-dimensional (2D) array of magnetodielectric circular cylinders which are distributed with any positions, sizes, and media on the xy-plane. Iterative- and closed-forms of the SBR-SP are used to understand the convergence and accuracy characteristics of a large array of cylinders and we also compare them with the results obtained by a mode-matching technique, thus resulting in favorable agreement. Especially, the closed-form of the SBR-SP with GPU acceleration is fast and accurate enough to obtain various echowidth behaviors of a 80×80 square array  within  71.8 s. In addition, a statistical analysis for a randomly distributed array with 6,400 elements is conducted in terms of mean and standard deviation and we obtain that initial shooting rays excited by an incident field are strongly dominant in statistical behaviors of scattering patterns. Our algorithm based on the SBR can be extended to three-dimensional (3D) problems where we model a large array of lossy dielectric spheres for the estimation of rain attenuation and signal variation.
ON THE ORIGINS OF ELECTROMAGNETISM
Authors: Dodig Hrvoje
Published: February 2023

The origin of electromagnetism has been a recurring question since the discovery of electricity. In the 19th century, Maxwell unified electricity and magnetism into a single electrodynamic theory described by Maxwell's equations. This was followed by the discovery of the electrodynamic force on a moving charge by Lorentz. Later, Einstein demonstrated that magnetism and the Lorentz force can be considered a relativistic effect.

However, despite these important theories, there is at present no physical theory that identifies the single fundamental cause of all known classical electromagnetism. In an attempt to identify this single fundamental cause, this paper shows that classical electromagnetism can be considered as effect of scalar waves emanating from charges. It is shown in this paper that Coulomb's law, Maxwell's equations, the magnetic and electric field, the Lorentz force, and the Lienard-Wiechert potentials, can all be derived only from this single hypothesis that scalar waves are emitted by the charges. In addition, it was shown that the Lorentz transformation can also be derived from this hypothesis of scalar waves.

To achieve this, an important new quantity was introduced: the momentum of the scalar waves. It was shown that the force caused by these scalar waves is simply the time derivative of this momentum. It was also shown that both the Lorentz force and the Coulomb force can be represented as the time derivative of the scalar wave momentum.

محاكاة النمو العمراني وتغير استعمالات الأرض في مدينة الديوانية باستخدام تقنيات الاستشعار عن بعد(RS) ونظم المعلومات الجغرافية (GIS)
Authors: العامري رافد
Published: February 2023

تسعى الدراسة الى استخدام تقنيات الاستشعار عن بعد ونظم المعلومات الجغرافية ، بوصفهما نظامين متكاملين في محاكاة النمو العمراني ورصد تغيرات استعمالات الأراضي في مدينة الديوانية خلال المدة (2000-2018) والكشف عن التباينات المكانية والزمانية التي ساهمت في التغيير خلال الثمانية عشر سنة الماضية ،فضلاً على التنبؤ بمستقبل التغيرات العمرانية المحتملة لغاية عام 2040، واعتمدت الدراسة على بيانات المستشعر (ETM+، OLI-TIRS) للقمر الصناعي (Landsat) بواقع مرئيتين فضائيتين للعوام (2000-2018) ، فضلاً على الاعتماد على خرائط التصميم الأساس المعدة من قبل مديرية بلدية الديوانية بمقياس (1:100000) ، واستنباط خريطة الامتداد العمراني والتغيرات المستقبلية لاستعمالات الأراض في منطقة الدراسة . وقد توصلت الدراسة ومن خلال تطبيق نموذج المحاكاة باستعمال نمذجة ماركوف (CA-MARCOV) الى تطور الكتلة العمرانية للمدينة الى (6406078) هكتاراً لغاية عام 2040، وعليه فأن محاور الانتشار العمراني المستقبلي للمدينة في ضوء احتمالية الانتقال سوف تتركز بنفس اتجاه الامتداد العمراني للكتلة العمرانية لعام 2018. بمعنى أنه لا توجد اختلافات جوهرية بين النموذجين من ناحية التوزيع المكاني للنمو العمراني من موقع الى آخر، فقد تمكنت الدراسة من التحقق من دقة خرائط المحاكاة مقارنة بخريطة عام 2018 باستعمال معامل (كابا) ، اذ أظهرت النتائج أن جميعها بتوافق عالٍ ، وسجلت قيمة (0.86) ، وهذا مؤشر على دقة عالية في عملية التصنيف .
الانتلجينيسيا في روايتي ساعة بغداد لشهد الراوي، و خواب زمستان لـگلي ترقّي. ( دراسة مقارنة )
Authors: عباس فلاح , عيسى ثائر
Published: February 2023

يتناول البحث روايتين من لغتين مختلفتين، رواية الكاتبة العراقية شهد الرّاوي التي حملت عنوان ساعة بغداد، ورواية الكاتبة الايرانية گلي ترقّي خواب زمستاني وترجمتها ( سبات الشتاء ). الكاتبة گلي ترقّي لها باع في كتابة الرواية والقصة، بينما عرفت الكاتبة شهد الرّاوي من خلال روايتها ساعة بغداد. تجشّمت الكاتبتان عناء الغربة، ولوعة الفراق والبعد عن الوطن، وانعكس ذلك جلياً في آثارهنّ. هنّ أيقونة المرأة الساعية لكسر القيود، والتقاليد السائدة في مجتمعيهما. مع الحفاظ على رابط الصلة بين الحياة في الغربة وبين الوطن، اذ بهما لم تجعلا من السلطات الحاكمة عدواً، يطارد أفكارهما العابثة في تركات الحكومات الجائرة والتقاليد السائدة، بل يعتقد الباحثان أنّهنّ هادنتا، من أجل إيصال رسالتيهنّ إلى المجتمع بشكل دقيق وجلي. الروايتين تنتميان للمذهب الواقعي، تحملان في طياتهما سمات المدرسة الانتقادية التي تشخص عيوب المجتمع وتشهرها للعلن

Published: February 2023

Familial neurohypophysial diabetes insipidus (FNDI), an autosomal dominant disorder, comes in many forms that are differentiated by the inheritance pattern and the underlying genetic lesion. The disease is caused by mutations in the vasopressin-neurophysin 2- copeptin protein (AVP-NPII), in wolframin (WFS1) or in proprotein convertase subtilisin/kexin type 1 (PCSK1) genes. Materials and methods: In this study, we report a case of familial neurohypophyseal DI in three generations; followed in unit of the endocrinology, diabetology, metabolic diseases and nutrition department of the Mohammed VI University Hospital of Marrakesh. Results: This was a 45-year-old patient who had been suffering from polyuro-polydipsia syndrome since the age of 12, with daily urine volumes ranging from 8.0 to 15.0 litres, but had not seen a doctor. The patient was born without complications and had normal puberty. In the family history, three other members of the patient’s family have also had polypolypolydispic syndrome since adolescence, covering three generations, including the patient’s mother, her younger sister and daughter. A water restriction test was performed but the patient did not tolerate it. We completed with the minirin test with a good clinical response: urine concentrated with a volume of 500ml, and urinary osmolarity at H4 of 276.13 (Fig 2). As presented in (Fig 3), cranial MRI revealed a hypersignal region in the posterior pituitary lobe. Serum cortisol, thyroid function, and estrogen were all in the normal range The growth hormone (GH), insulin like growth factor (IGF)-1 levels and the genetic testing were not performed due to limited financial resources. After treatment with oral desmopressin 60 ug two times daily was started, the symptoms of polydipsia and polyuria were satisfactorily controlled.

Cholecystectomy is now-a-days done mostly by laparoscopy rather than open procedure. Post- cholecystectomy complications are not uncommon but somewhat it seems post laparoscopic cholecystectomy complications are not fewer in comparison to open. Among various complications, post-cholecystectomy clip migration is one of the rare ones. It can happen anytime but mostly occurring around 2 years of operation. Clinical presentation varies, as described in literatures but mostly presents with choledocholithiasis. Here we present such a case in a 25-year-old lady who was a bit challenging due to unusual presentation and long course of illness.

EFFECT OF ACUMETRIC TEST ON STUDENTS PERFORMANCE IN K-12 MATHEMATICS 6
Authors: Winston Mark C. Coquilla
Published: February 2023

The study employed quasi – experimental research to investigate the effect of Acumetric Approach on students’ performance on Integers in Mathematics 6. The participants were two sections of Grade 6 students at Mabunao Elementary School, Barangay Mabunao, Panabo City, Phillipines. One section was assigned as control group, which was exposed to conventional approach with usual motivation and varied activities given in typical classroom teaching, while the other was the experimental group, which was exposed to Acumetric Approach, giving a game-based design repeated activities on non-digital mode, wherein the games were printed and instructions were provided. Pre-test and Post-test were administered prior and after experimentation. The pre-test results reflected that both groups had a low level of performance and no significant difference. After the post-test, both groups had increased their level of performance of which the control group developed from low to average level while the experimental group moved from low to mastery level. The post-test results had shown that there was a significant difference on their mean percentage score. Moreover, by controlling the Pre-test as covariate, the result significantly improved the performance level of the experimental group with a p-value of <0.05. Hence, the experimental group performed better than the control group. Thus, Acumetric Approach can improve the achievement of students in Mathematics.

Published: February 2023

Studies on the move analysis in the various sections of  research articles have developed rapidly. However, the studies on the communicative moves in the discussion section particularly written by vocational college students are still limited. In fact, those students categorized as the novice writers inevitably need illustrations of how to write the proper discussion related to their findings. Therefore, this study was aimed at exploring the communicative moves and the move cycle series in the discussion sections of the final project reports written by EFL vocational college students in one of the state polytechnics in Indonesia. The method used is a discourse analysis on 15 discussion sections. The results showed that Move II, Move IV, and Move I were used frequently in all students’ discussion sections. Pertaining to the move cycle series, students fulfilled the rhetorical functions of introduction (1) and evaluation (4+2 or 2+4) but the cycle for showing the conclusion was commonly not used. The results provide references and the real applications pertinent to communication moves in the discussion section by EFL students.
