Capsicum frutescens L. is one of the most important horticultural commodities in Indonesia. One of the obstacles that are often faced by farmers in chili cultivation is the low ability of chili seeds to germinate because of the seed deterioration during the storage period. The low ability of seed germination can be solved by using organic priming treatment. In this study, the invigoration of expired chili seeds was carried out using organic priming of shallots extract, mungbean sprouts extract, onions + mungbean sprouts extract, and water as a control treatment. Based on the results of the study, organic priming of expired chili seeds using onion extract and a mixture of onion + mungbean sprouts was able to increase seed germination, but the treatment using mungbean sprouts extract had lower seed germination than the control treatment. Organic priming had no significant effect on the vigor index of expired chili seeds. Shallots extract was the most optimal organic priming for invigorating expired chili seeds.

Study on Malaria Detection Using Transfer Learning
Authors: Mayya Rajesh , Chopra Shalu , Vijayalakshmi M.
Published: November 2022

Abstract: The occurrence of Deep Learning models has substantially reformed the field of intelligent systems inheriting the likewise human behavior. These systems use Deep Neural Networks architecture, that is, to be effective in applying analytical and logical thinking to solve in all applicable fields. Deep Learning has pushed us to the limits in the domain of Digital Image Processing which had been in progressive development these years. Malaria is now a lethal, life-threatening disease by Anopheles mosquito bite spread through Plasmodium parasites. This process needs trained experts or qualified technicians, to examine the spread-out blood smears under the microscope. In this paper, we put forward a comparative study of deep Learning techniques for malaria detection. We first classify the cell images. We apply convolutional neural networks (CNNs) to distinguish the cells. Then, we analyze the models using a pre-trained learning approach, where the classification of infected cells improves diagnostic accuracy. This study uses Inception-V3, NasNetMobile, MobileNetV2, Xception, and VGG-19 models for analysis. Many Deep learning algorithms can be used to predict malaria, but in this study, MobileNetv2 and Inception-V3 models have better accuracy.

Published: November 2022

Abstract— Tofu is an oriental food that originated from China and later became a traditional cuisine in many South East Asia Countries, e.g. Indonesia, Singapore, and Thailand. The tofu was made by coagulating soy milk with salt to form curds, which further compress to form a solid block. Tofu usually uses soybeans as the main ingredients; however, in this experiment, the soybeans were partially replaced with chickpeas to increase the amount of dietary fibre and reduce fat levels in the final products. The tofu was made of soybean and chickpea at a ratio of 100:0 (control), 90:10, 80:20 and, 70:30.  The products were evaluated based on their nutritional contents (crude protein, crude fat, and crude fibre), and textural properties using Texture Profile Analysis. Some analytical parameters, such as pH, moisture content, and colour were also studied. Partial replacement of soybean with chickpea decreased overall crude protein and fat content, whereas increased crude fibre. The presence of chickpea in the blends, up to 30% (w/w), had affected the tofu curd's protein stability, lowered their pH, and moisture content.  A denser tofu curd was obtained by adding more chickpea to the product. The 70:30 blend has the highest hardness value compared to the other formulations. This low soy content mixture, however, can not produce a cohesive and springy tofu gel. The CIELAB colour space of the soybean/chickpea tofu cubes records a trend of increase in redness and yellowness values for tofu with chickpea.
Light-harvesting activity is targeted by photosystem I photoinhibition in rice plants irrespective of photosystem I photoinhibitory treatments

Published: November 2022

Overreduction states of photosystem I (PSI) cause PSI photoinhibition.
To examine the degree of PSI photoinhibition, changes in its electron
transport activity and core-subunit content were evaluated. In contrast,
the involvement of peripheral subunits, such as the light-harvesting
complex I (LHCI), is less discussed in PSI photoinhibition. Here, we
aimed to elucidate whether the light-harvesting functions of LHCI are
altered by PSI photoinhibition in rice leaves. To this end, a new method
to estimate the functional antenna size of the PSI-LHCI complex was
developed using a far-red light-dependent absorption change in the
oxidized reaction center chlorophyll (P700 ) in
intact leaves, and the obtained kinetics were analyzed using the double
Gompertz model. Subsequently, our original parameter,
k (Far Red-Photon Flux Density)
, showed a linear response to leaf LHCI content, and
the parameter decreased with a decrease in P700 content by PSI
photoinhibition in leaves. Furthermore, we found that the susceptibility
of LHCI to PSI photoinhibitory treatment decreased with increasing in
growth light intensity. Our results suggest that LHCI is a target of PSI
photoinhibition, as well as the core-subunits, and rice plants can lower
the risk of LHCI photoinhibition through light acclimation responses.
Investigation on the underwater noise from ships in the upper Yangtze River
Authors: Lei Zonglin , DU Hongbo , WAN Yu , LI Wenjie
Published: November 2022

Due to the implementation of many regulation projects in the upper
Yangtze River, the vessel transit capacity has been improved visibly.
The trend of large-scale ships becomes more obvious, leading to an
increase of the traffic flow and underwater noise density in the upper
Yangtze River, which has significant influence on the habitat of many
aquatic animals, especially for the endemic fish. Thus, it is crucial to
accurately assess the ship underwater noise conditions for the
ecological protection in the upper Yangtze River. In this study, the
underwater noise from different types of ships under the normal
operating conditions in the Chaotianmen-Fuling section has been
monitored using the underwater noise tracking and monitoring system. The
results indicate that the frequency of underwater radiation noise from
ships is concentrated in the range of 200Hz~1300Hz, and
the sound pressure level is distributed in the range of
148.50dB~172.86dB, and the underwater radiation noise
energy is concentrated in the low frequency part. The sound pressure
level of underwater radiation noise from ships is proportional to the
ship speed and ship tonnage. The research results can provide
theoretical support for the subsequent research on the underwater noise
distribution in such waterways as well as the ecological route
selection.
Automated patent classification for crop protection via domain adaptation

Published: November 2022

Patents show how technology evolves in most scientific fields over time.
The best way to use this valuable knowledge base is to use efficient and
effective information retrieval and searches for related prior art.
Patent classification, i.e., assigning a patent to one or more
predefined categories, is a fundamental step towards synthesizing the
information content of an invention. To this end, architectures based on
Transformers, especially those derived from the BERT family have already
been proposed in the literature and they have shown remarkable results
by setting a new state-of-the-art performance for the classification
task. Here, we study how domain adaptation can push the performance
boundaries in patent classification by rigorously evaluating and
implementing a collection of recent transfer learning techniques, e.g.,
domain-adaptive pretraining and adapters. Our analysis shows how
leveraging these advancements enables the development of
state-of-the-art models with increased precision, recall, and F1-score.
We base our evaluation on both standard patent classification datasets
derived from patent offices-defined code hierarchies and more practical
real-world use-case scenarios containing labels from the agrochemical
industrial domain. The application of these domain adapted techniques to
patent classification in a multilingual setting is also examined and
evaluated.
Left Ventricular Summit Premature Ventricular Contractions treated by Venous Ethanol Infusion: Scar Assessment by magnetic resonance imaging
Authors: Limite Luca Rosario , Laborie Guillaume , Constantin Justine , Maubon Antoine , Arcari Luca , Hebert Caroline , Bortone Agustin
Published: November 2022

Introduction: left ventricular (LV) summit premature
ventricular contractions (PVCs) are often unresponsive to radiofrequency
(RF) ablation. Retrograde venous ethanol infusion (RVEI) can be a
valuable alternative in this scenario. Methods: a 43‐year‐old
woman without structural heart disease presented with LV summit PVCs
unresponsive to RF ablation because of their deep-seated origin.
Results: Unipolar pace mapping performed through a wire
inserted into a branch of the distal great cardiac vein (GCV)
demonstrated 12/12 concordance with the clinical PVCs thus indicating
close proximity to PVCs’ origin. RVEI abolished the PVCs without
complications. Subsequently, magnetic resonance imaging (MRI) evidenced
an intramural myocardial scar produced by ethanol ablation.
Conclusions: RVEI effectively and safely treated PVC arising
from a deep site in the LVS. The scar provoked by chemical damage was
well characterized by MRI imaging.

Published: November 2022

Microalgae play an essential role in agriculture as bio-fertilizers and
biostimulants, but some also produce various plant hormones, such as
cytokinins (CK). CK are a class of natural plant hormones and there is
evidence that exogenous or bacterial CK can modulate plant defense.
However, there is a lack of knowledge about the effect of specific
microalgae or microalgae-produced cytokinins on this response. In our
study, we have evaluated the cytokinins-producing microalgae
Chlamydomonas reinhardtii (Cri) on its ability to prime
Nicotiana tabacum plant defenses against its natural pathogen
Pseudomonas syringae pv. tabaci. Our work functionally
verifies that Cri primes plant defense response, with cytokinins
being a crucial component. We have used the CRISPR/Cas9 system to
generate CriLOG and IPT gene knockouts, which are
major points of the CK biosynthesis pathways. While Cri shows
strong protection potential, the CK-deficient mutants have a reduced
ability to affect plant defense, where the degree of protection
correlates with the CK levels - the IPT mutants show less
protection than the LOG mutants. Additionally, by measuring plant
defense gene expression by RTq-PCR we have shown that Cri
treatment stimulates tobacco defense response by priming.
Digital Twin Simulation Modeling Process with System Dynamics: An application to Naval ship operation
Authors: choi jinwoo , Moon Seongam , Min Soonhong
Published: November 2022

Digital twin (DT) has been around for many years, but there is no widely
accepted standardized tool or method. In this study, system dynamics was
proposed as a tool that can be integrated into multi-scale,
multi-physics, and multi-disciplinary, which are continuously becoming
issues in the DT field. Various heterogeneous data from multiple
protocols or platforms could be integrated into one model. Through the
five-step model building process, it was possible to integrate the
theories and various models studied in the past. In this study,
the operation and maintenance system of ROK Naval ships is
implemented as a proposed method. Various physics, scales, and
disciplines such as failures of ships, maintenance ability of repair
shops and schedule pressure of mechanics were reflected. It was possible
to observe non-intuitive correlations and potential problems caused by
the latent effect of the high-fidelity DT model. The proposed method is
also capable of updating through continuous data calibration or
real-time interworking with external statistical analysis tools.
Non-Destructive and Contactless Defect Detection inside Leading Edge Coatings for Wind Turbine Blades using Optical Coherence Tomography
Authors: Petersen Christian , Fæster Søren , Bech Jakob , Jespersen Kristine , Israelsen Niels , Bang Ole
Published: November 2022

Leading edge erosion of wind turbine blades is one of the most critical
issues in wind energy production, resulting in lower efficiency, as well
as increased maintenance costs and downtime. Erosion is initiated by
impacts from rain droplets and other atmospheric particles, so to
protect the blades special protective coatings are applied to increase
their lifetime without adding significantly to the weight or friction of
the blade. These coatings should ideally absorb and distribute the force
away from the point of impact, however, microscopic defects, such as
bubbles, reduce the mechanical performance of the coating, leading to
cracks and eventually erosion. In this work, Optical Coherence
Tomography (OCT) is investigated for non-destructive, contactless
inspection of coated glass-fiber composite samples to identify
subsurface coating defects. The samples were tested using rubber
projectiles to simulate rain droplet and particle impacts. The samples
were subsequently imaged using both OCT, optical microscopy, and X-ray
tomography. OCT scanning revealed both bubbles and cracks below the
surface, which would not have been detected using ultrasonic or similar
non-destructive methods. In this way, OCT can complement the existing
quality control in turbine blade manufacturing, help improve the blade
lifetime, and reduce the environmental impact from erosion.

Mapping Natural Exposures of Siliceous Marls and Cherts as Potential Zones of Raw Material Acquisition. The Case of the Eastern Polish Carpathian Foothills and the Rzeszów Settlement Region (SE Poland) in the Neolithic and Bronze Age. Preliminary Results
Authors: Pelisiak Andrzej
Published: November 2022

The Neolithic and Bronze Age communities that settled the eastern Carpathian Forelands and Carpathian Foothills used a variety of local and non-local siliceous raw materials. Raw materials identified in the archaeological record differ in quality and usefulness for making tools. Obsidian, Jurassic flint from the Cracow-Częstochowa Upland, chocolate flint, or Świeciechów and Volhynian flints represent the best quality. On the other hand, some local raw materials were also in use, most popular among them being siliceous marls and cherts. Sources of siliceous marls and cherts are known from many locations in the Dynów, Strzyżów and Przemyśl foothills. Moreover, systematic field surveys in this area have provided new information on the availability of cherts and siliceous marls at many new locations in the region. They appear in the primary autochthonous, secondary autochthonous, and more rarely in sub-autochthonous or residual, sources. Exposures on steep hill slopes and dissected river valleys provide easy access to the best quality raw materials in the primary autochthonous sources. Raw materials from secondary autochthonous sources in the riverbeds were also available, but they were of lesser quality than those from the exposures. The aim of this paper is to present natural exposures of siliceous marls and cherts and discuss them as a potential source of raw materials for the Neolithic and Bronze Age communities inhabiting loess areas of the eastern Carpathian foreland (Rzeszów Settlement Region).

This paper presents the current state of research on the Early Neolithic flint quarry of Pozarrate (Treviño, Burgos) in the north of Spain. This site is part of the Prehistoric Flint Mining Complex of Treviño. The geological features of the territory made it a suitable place for the exploitation of the Treviño flint since Paleolithic times, especially during the Neolithic. Recent research at the site has revealed interesting findings, such as antler and dolerite mining equipment and different flint tools, among other recoveries. Radiocarbon dates indicate an Early Neolithic activity which makes Pozarrate one of the few flint procurement sites in the Iberian Peninsula from this period. Moreover, a considerable number of elements link Pozarrate to the Early European Neolithic flint mining phenomenon.

Del to introduserer spenningen mellom forskeren som analytiker og forskeren som kommentator og påpeker at vi ikke vet så mye om hvem debatten snakker til ut over det utenrikspolitiske miljøet selv. Del tre diskuterer hva slags standarder akademikere som opptrer som kommentatorer kan og bør holde seg med. Kommentatorer må ha mot, evne og vilje til å gi rom for andre stemmer. Kommentatoren må også forstå forskjellen på analyse, som krever ettertenksomhet, og kommentar, som skjer i kampens hete.

Professional Learning Community (PLC) is a platform that is recognizable to the development of professionalism among educators as well as the aspects of teaching and learning of educators. A professional learning community, or PLC, is a group of educators that meets regularly, shares expertise, and works collaboratively to improve teaching skills and the academic performance of students. Therefore, an initiative has been taken by the Institute of Teacher Education Malaysia (IPGM) to cultivate PLC among teacher educators in all 27 IPGs in Malaysia. One of the collaborative tools recommended for its application is Lesson Study (LS). LS is seen as a collaborative tool that focuses on student learning and is implemented collaboratively. A study was conducted by applying LS in the Teaching and Learning process (PdP) at Raja Melewar Teacher Education Institute to student teachers in the Post -Education Diploma Program (PDPP) for Philosophy and Educational Development in Malaysia (EDUP2072). The students involved are students majoring in History and TESL. A total of two cycles were implemented and the results of each cycle were shared with fellow teacher educators and given improvements before the implementation of the 2nd cycle. Observations were carried out during the TnL process by seven fellow teacher educators as well as one expert. A reflection session was held immediately after the end of each TnL and discussed. The results of the study found that i. LS can provide an impact on student learning towards better understanding and clarity, ii. Collaboration between teacher educators can produce a healthy culture in the organization and iii. Cultivation of LS among teacher educators can promote the cultivation of PLC in Teacher Education Institutes in Malaysia. Overall LS and KPP should be given focus by all instructional leaders in Teacher Education Institutes and The Institute of Teacher Education Malaysia (IPGM) as a culture and in an effort to develop the professionalism of teacher educators.

The human skeletal system is a complex material to be studied by students, especially for social studies class students who take Biology specialization subjects. This study aims to train students' creativity and improve students' mastery of concepts in the joint subtopic of skeletal system material through a STEM approach with a Project Based Learning model based on lesson study. The research method was a weak experiment with a one-shot case study design. The instruments used in this study include multiple choice test instruments and observation sheets. The results showed that students' creativity was in the good category with mastery of concepts that had passed the minimum KKM limit. This shows that STEM learning with project-based learning helps students to be able to understand the concept of joints through the implemented projects. The planning and implementation of lesson study-based learning also stimulates collaboration between teachers in the field of study to be able to design innovative learning.

Policies that are present have contributed to driving the nation's economy. With Presidential Regulation Number 91 of 2017 the government issued a policy to speed up and facilitate business services by using the Electronically Integrated Business Licensing System (Online Single Submission). The problems with the Online Single Submission (OSS) at the Tanjungpinang City Investment and One-Stop Integrated Services Service are, first, the network at the center is often disturbed so that it is difficult for regions to access OSS. The licensing database in OSS has not been clearly classified, so regions have to sort out data again and enter data manually which causes the process of issuing a permit to take a long time. The purpose of this study is to provide an explanation in the government network which is a form of public sector collaboration. The method used is qualitative based on two sources of primary and secondary data in the form of interviews, institutional databases, websites, and previous research. The results show that the OSS system in Tanjungpinang City has had a positive impact on business actors, with the convenience offered by the OSS system, many Micro Enterprises have been built using the OSS system management service. However, there are still obstacles, such as the absence of a Regional Regulation that regulates in more detail the application of the system, so there is a need for an in-depth analytical study so that the use of the OSS system can be used more effectively with more binding derivative rules.
Types and Sources of Moroccan EFL Students’ Errors in Writing: A Study of Error Analysis
Authors: AKNOUCH Layla , BOUTHICHE Hassane
Published: November 2022

Language teachers and researchers argue that the process of learning a language is better understood if the errors that language learners make in constructing the new language system are carefully analyzed. Hence, analyzing errors has become essential for facing and overcoming problems and suggesting solutions regarding different aspects of language teaching and learning. Accordingly, this study seeks to examine the errors that Moroccan high school students of English make in writing, and investigate the reasons behind the occurrence of such errors. The sample of the study consists of students’ essays collected from different classes. The data collected were analyzed using Corder’s (1967) model, which includes three stages; data collection, description, and explanation. The study’s findings showed that Moroccan EFL students make different types of errors in writing. The most significant number of the errors found in the students’ essays are grammatical errors, and most of these errors are due to intralingual factors.
Стійкість граничних режимів для загального випадку систем типу реакція-дифузія.
Authors: Капустян О. В. , Юсипів Т. В.
Published: November 2022

У цій статті ми розглядаємо стійкість граничних режимів для загального класу нелінійних розподілених математичних моделей, які називаються моделями реакції-дифузії. Системи реакції-дифузії природно виникають у багатьох застосуваннях. Наприклад, при математичному моделюванні в біології та у теорії передачі сигналів широко використовується модель ФітцХью–Нагумо (FitzHugh–Nagumo model), розподілений варіант якої є окремим випадком загальної системи реакції-дифузії. Досліджено проблему стійкості притягуючих множин для нескінченновимірної системи реакції-дифузії відносно обмежених зовнішніх сигналів (збурень). Функції взаємодії, а також нелінійні збурення не вважаються неперервними за Ліпшицем. Отже, ми не можемо очікувати єдиності розв’язку для відповідної початкової задачі, і ми повинні використовувати багатозначний напівгруповий підхід. Вважається, що незбурена система має глобальний атрактор, тобто мінімальну компактну рівномірно притягаючу множину. Основною метою дослідження є оцінка відхилення траєкторії збуреної системи від глобального атрактора незбуреної як функції величини зовнішніх сигналів. Таку оцінку можна отримати в рамках теорії стійкості входу до стану (ISS). У статті запропоновано новий підхід до отримання оцінок робастної стійкості атрактора у випадку багатозначного еволюційного оператора. Зокрема, доведено, що багатозначна напівгрупа, породжена слабкими розв’язками нелінійної системи типу реакції-дифузії, має властивість локальної ISS відносно атрактора незбуреної системи.
Про кількість емігрантів в розкладному гіллястому процесі з перетвореннями, залежними від віку
Authors: Лисецький Т. Б.
Published: November 2022

Розкладний гіллястий процес можна розглядати як стохастичну модель популяції з N типами індивідиумів, розділених на декілька підгруп G1, G2, ..., GN, n≤N, де кожна група населяє окремий острів. Індивідиум з групи Gi може одразу після народження емігрувати на острів, населений групою з вищим індексом, або залишитись на своєму острові. В даній статті розглядається випадок з двома групами G1 та G2. Кожна особа має випадкову тривалість життя, а розподіл її потомства залежить від її віку.
Ми досліджуємо асимптотичну поведінку процесів, які рахують кількість частинок, що емігрували, в залежності від критичності гіллястого підпроцесу, породженого групою G1.
THE ROLE OF STRUCTURALISM IN TOWN PLANNING RESEARCH IN THE DIGITAL ARCHITECTURE ERA
Authors: Muljadinata, M.T. Albertus Sidharta
Published: November 2022

At first, Structuralism developed rapidly in France, but structuralism was not yet known in Indonesia; even in the early 1990s, Lévi-Strauss' structuralism did not resonate with Indonesian socio-cultural scientists. In 1966 the publication of the book The Architecture of the City, authored by Aldo Rossi, provided input on architectural and urban research based on structuralism; This book teaches Typomorphology. The purpose of this study is to provide an explanation of how structuralism is used as an approach method in town planning research. There are two research methods used, the first is a literature review method to gain an understanding of structuralism and the use of structuralism in the field in the context of town planning, namely the typomorphology approach. After this understanding, followed by the second research method, namely the case study method, which is to explain the use of the structuralism method in case studies in Semarang City. The research provides an understanding of structuralism, and an understanding of the use of structuralism in the scope of architecture, particularly in town planning research. In the current era of digital architecture, the results of this study provide an overview of the important role of structuralism in contributing to the facts of all aspects that make up the city; and this is the basis for research on urban development using digital architectural technology.
