Taxonomic Revision of Serpocaulon (Polypodiaceae)
Authors: Sanín David , Salino Alexandre , Smith Alan R.
Published: October 2023

We present a taxonomic revision of Serpocaulon A. R. Sm. (Polypodiaceae), a tropical American fern genus. Our work is based on a morphological analysis of 56 characters recorded from 2167 specimens deposited in 41 herbaria. Field trips were carried out in Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Panama, and Peru, where observations on the habit and habitat of several species were made. Digital images were also consulted. A total of 260 names were found and their nomenclatural types were studied, resulting in the lectotypification of 47 names (first-step 30, second-step 17 names). We recognize 37 species and five hybrids in Serpocaulon; one of the hybrids is given a new status (S. ×semipinnatifidum (Fée) A. R. Sm.) and another one is described (S. ×tabuleirense D. Sanín & Salino). Moreover, 19 names are newly synonymized, five species are excluded, 17 names are considered as of uncertain application, and five as nomina nuda. We document for 22 species a total of 62 chorological novelties in different countries. The elevational range of the genus is 0–4200 m. The Andes of Ecuador and Colombia are the main center of diversity and endemism; secondarily, the Atlantic Rain Forest of Brazil has five endemic species. We provide a taxonomic key, descriptions, discussions, local names, uses, illustrations, photographs of the plants in the field, microphotographs of the rhizome scales and the spores, and distribution maps of all species.
Five New Species of Aniba (Lauraceae) from Colombia, Ecuador, and Peru
Authors: Van der Werff Henk
Published: October 2023

Five new species of Aniba Aubl. (Lauraceae) with clustered or verticillate leaves are described and illustrated. Aniba brochidodroma van der Werff from Peru stands out by its short petioles and soft whitish hairs on the lower leaf surface. Aniba glabra van der Werff from Colombia is distinguished by its glabrous flowers and inflorescences. Aniba palaciosii van der Werff from Ecuador can be recognized by the indument of the outer surface of the tepals, with the outer three tepals finely appressed pubescent and the inner three tepals glabrous. Aniba tomentella van der Werff from Peru differs from its congeners in its flower shape; its flowers are wider than long and the tepals are incurved leaving only a small apical pore. Finally, A. verticillata van der Werff from Ecuador differs from morphologically similar species by its subcoriaceous leaves with prominently raised secondary veins and its montane habitat.

Los microorganismos presentes en su entorno influyen en el crecimiento de las plantas y pueden ser mutualistas, como los hongos formadores de micorrizas, o no mutualistas, como los hongos endófitos. En este estudio se aislaron especies fúngicas de la raíz y suelo rizosférico de arándano (Vaccinium corymbosum L.) cultivado en el estado de Michoacán, México con la finalidad de analizar su potencial como promotores de desarrollo vegetal. Seis cepas fúngicas fueron identificadas molecularmente mediante las regiones del espaciador transcrito interno (ITS) del ADN ribosomal. Se evaluó su capacidad de modificar el desarrollo de plántulas de Arabidopsis thaliana (Col 0) mediante dos configuraciones experimentales (cajas Petri compartimentadas y no compartimentadas), para investigar la influencia de compuestos difusibles y volátiles sobre el fenotipo de la planta. Phialocephala fortinii y Mortierella alpina promovieron el crecimiento de Arabidopsis thaliana, sobre todo en cajas compartimentadas, donde se observó un incremento de la longitud de raíz principal (≥ 2 cm) y en el número de raíces laterales (≥ 34), sugiriendo que los compuestos volátiles son los responsables de estos incrementos. Las especies promotoras de desarrollo vegetal seleccionadas se evaluaron mediante líneas reporteras ARR5::GUS y DR5::GUS para estimar la respuesta de genes a la acumulación de citocininas y auxinas en los tejidos vegetales. Los resultados indican que Phialocephala fortinii y Mortierella alpina actúan diferencialmente sobre el crecimiento de las plantas y representan un recurso biológico con gran potencial para su uso como bioestimulantes en la agricultura actual.

Published: October 2023

El cafeto (Coffea arabica L.) es una especie de importancia económica mundial y su producción se basa en la aplicación de insumos químicos de origen sintético. El aumento en la preferencia del consumo de café orgánico ha utilizado varias alternativas para la nutrición del cultivo, como los hongos endomicorrízicos. El cafeto presenta alto grado de micotrofia; sin embargo, su efectividad es diferencial al inducir el crecimiento. El objetivo del presente estudio fue evaluar el efecto de hongos endomicorrízicos de diferente origen geográfico en el crecimiento de Coffea arabica L. cv Catimor y en el contenido de fosforo en tejido vegetal. Las semillas fueron germinadas en charolas y a las dos semanas fueron biofertilizadas y trasplantadas a suelo andosol mólico en bolsas de plástico con los aislamientos denominados Limón, Vainilla, Izapa, Caracoles y San Rafael, además de Rhizophagus intraradices como referencia, y un testigo. Se utilizó un diseño completamente al azar con cinco repeticiones. Se registraron variables morfológicas (altura de planta y número de hojas) y fisiológicas (biomasa seca de raíz, tallo, lámina foliar y área foliar) a los 28, 56, 84 y 112 días después del trasplante, además de colonización radical y contenido de P en tejido vegetal al final de la evaluación. Se encontraron diferencias en inducción de materia seca con los aislamientos, y todos superaron al testigo. La altura de planta presentó aumento más uniforme con los aislamientos. La biomasa seca se incrementó desde el primer muestreo en las variables tallo y lámina foliar y a partir del segundo en raíz. Los valores de las variables morfológicas y fisiológicas se expresaron diferencialmente en relación con el tiempo, y la inducción del crecimiento fue influenciada por los aislamientos. El contenido de fósforo se incrementó en todas las plantas colonizadas en comparación al testigo.

Published: October 2023

Las especies del género Agave se usan para obtener fibras y azúcares. En Oaxaca, México, hay 10 mil hectáreas cultivadas con diversas especies de este género, y 80 % de esta área es cultivada con A. angustifolia Haw. Las plantaciones se establecen con plantas propagadas asexualmente, provenientes de estructuras como vástagos de rizomas, bulbilos de inflorescencias y plantas obtenidas mediante micropropagación. El ambiente de cultivo in vitro afecta las características fisiológicas y morfológicas de las plantas micropropagadas y su adaptación a las condiciones ex vitro. El objetivo de este estudio fue determinar la influencia del ambiente de incubación y del sustrato utilizado para la aclimatación de las plantas de A. angustifolia obtenidas in vitro sobre su supervivencia, características morfológicas y crecimiento. Brotes adventicios se enraizaron en laboratorio con iluminación LED. Las plantas regeneradas se cultivaron durante 31 días en dos ambientes de incubación, laboratorio con iluminación LED o estructura de sombra parcial. Para su aclimatación, las plantas se transfirieron a sustratos que contenían turba (T) y perlita (P) en proporciones 50T:50P, 25T:75P y 0T:100P, permaneciendo durante 65 días dentro una estructura con sombra parcial y 30 días en un vivero. Después de 65 días de aclimatación, 100 % de las plantas provenientes tanto de los cultivos in vitro, incubados tanto en la estructura de sombra parcial como en el laboratorio, sobrevivieron cuando se establecieron en el sustrato 50T:50P. Al término de la aclimatación, las plantas originadas de cultivos incubados en la estructura de sombra parcial, que crecieron en el sustrato 0T:100P, tuvieron mayor diámetro de tallo, número de raíces, volumen de raíces, peso seco aéreo y de raíz, y menor altura, número de hojas y área foliar que las plantas provenientes de cultivos in vitro incubados en el laboratorio.
USING AUTOVENOUS PLASTY FOR THUMB REPLANTATION
Authors:   Republican Scientific Center for Cardiovascular Surgery, Dushanbe, the Republic of Tajikistan, Джононов Д. Д.
Published: October 2023

The study aims to evaluate the effectiveness of autovenous plasty for thumb replantation. From 2014 to 2021, the Republican Scientific Center for Cardiovascular Surgery (Dushanbe) performed 18 thumb replantations and revascularizations, with 8 (44.4%) patients having complete traumatic thumb amputation and one patient undergoing replantation using autovenous plasty for primary fusion of the metacarpophalangeal joint. After the surgical interventions, 94.4% of patients showed positive results, including 7 patients (39%) with completely engrafted replanted parts preserving thumb function, whereas one patient (5.6%) demonstrated signs of ischemia of the replanted part of the thumb. Thus, in the case of crushed and avulsion traumatic amputations with damaged anatomical structure of a large part of the vascular-nervous bundle and virtually no chances for successful replantation, radial digital autovenous plasty allows expanding the indications for thumb eplantation, which is critical for the hand function.

Published: October 2023

The study investigates whether the design of a combined intervention with selfanalysis of re-contextualized sample texts and subsequent peer interactions might be promising in supporting writing skills development ofVietnamese EFL students in a virtual environment. A pretest-posttest control group design with switching replications was set up with one experimental condition of the combined intervention and one conventional condition with teacherled analysis of textbook-based samples. Participants included 97 Vietnamese English-majored undergraduate students in the third year in a university in Mekong Delta, Vietnam: 46 studentsin the experimental condition and 51 students in the control condition. Univariate covariance analyses showed that experimental condition had a positive effect on quality of texts. For writing fluency, students of the experimental condition wrote longer texts in the second panel (posttest 2); the effect could not be seen immediately in the first panel (posttest 1). Implications for EFL writing pedagogy and research, includingresearch planning to avoid the effect of topic on quality of writing, importance of writing topics relevant to L2 student writers, and organization of prewriting sessions are discussed in the last part of the paper.

Authors: Cu Pham Thien
Published: October 2023

A study of cercariae and snail composition by morphological analysis method in Hiep Phuoc rice field of Nha Be District, Ho Chi Minh City, Vietnam, was carried out in October 2022 (the wet season) and February 2023 (the dry season). A total of 738 snails were collected, and eight snail species belonging to eight genera and six families were identified. Six snail species were found in the wet season, and seven snail species were found in the dryseason. Only Sermyla tornatella was infected with trematode (cercariae stage), and the prevalence in the dry season (1.4%) was higher than in the wet season (0.9%) (P > 0.05). The other seven snail species were cercariae-free. Four cercariae morphotypes were recovered from Sermyla tornatella, including Transvesotrema cercariae,Pleurolophocercous cercariae, Xiphidio cercaria, and Echinostome cercariae. Further research on snails and their cercariae in other waterbodies should be done in Nha Be District to identify the snail diversity and sources of trematodes to contribute to developing tilapia culture and other fish species with trematode free.

Authors: Kürzinger Anja , Füting-Lippert Angelika , Pohlmann-Rother Sanna
Published: October 2023

Für den deutschsprachigen Raum liegen bislang kaum Befunde vor, die explizit die Technikbereitschaft von Lehramtsstudierenden fokussieren und Zusammenhänge zwischen mediendidaktischen Überzeugungen angehender Grundschullehrkräfte und ihrer Technikbereitschaft thematisieren. Gerade aus einem genaueren Verständnis des Zusammenspiels dieser Konstrukte lassen sich jedoch Impulse für medienbezogene Professionalisierungsprozesse von angehenden Grundschullehrkräften ableiten. Mit Blick auf dieses Forschungsdesiderat werden in der vorliegenden Studie Überzeugungen von Lehramtsstudierenden zum Einsatz von Tablets im Grundschulunterricht analysiert und ihr Zusammenhang mit der Technikbereitschaft beleuchtet. Im Unterschied zu bisherigen Untersuchungen liegt der Fokus explizit auf Tablets als ein spezifisches digitales Medium, da eine Beziehung zwischen dem jeweiligen Medium und den Überzeugungen angenommen wird. Leitend für den vorliegenden Beitrag sind dabei folgende Fragestellungen: (1) Welche Überzeugungen zum unterrichtlichen Lehren und Lernen mit Tablets besitzen angehende Grundschullehrkräfte und wie lässt sich ihre Technikbereitschaft beschreiben? (2) Welcher Zusammenhang besteht zwischen den mediendidaktischen Überzeugungen angehender Grundschullehrkräfte und ihrer Technikbereitschaft? (DIPF/Orig.)

Nachhaltige Bildungsprozesse in inklusiven Übergängen grundlegen – anschlussfähige Förderung Früher Literalität bei Kindern mit erheblichen domänenspezifischen Lern- und Entwicklungsherausforderungen
Authors: Liebers Katrin , Redersborg Helke , Ratz Christoph
Published: October 2023

Für die Gruppe der Kinder, deren literale Kompetenzen im Übergangsjahr noch im basalen oder prä-literalen Bereich zu verorten sind, gibt es bislang kaum allgemein etablierte oder empirisch bestätigte Modelle einer ressourcenorientierten Beschreibung früher Kompetenzausprägungen. Ebenso fehlen weitgehend diagnostische Instrumente, mit denen deren Kompetenzen so erfasst werden können, dass sich daraus adaptive Förderangebote auf einer mikrodidaktischen Ebene ableiten lassen. Im BMBF-Verbundprojekt ILEA-Basis-T wird deshalb an zielgruppenspezifischen Diagnose- und Förderbausteinen gearbeitet, mit denen die frühen literalen Kompetenzen von Kindern mit ELE im letzten Kindergartenjahr ressourcen- und förderorientiert erfasst werden können. Damit soll zu einer verbesserten domänenspezifischen Anschlussfähigkeit während des inklusiven Übergangs in die Schule beigetragen werden. Im folgenden Beitrag werden dazu die theoretischen Vorarbeiten, das Forschungsdesign sowie erste Befunde aus der Pilotierung vorgestellt. (DIPF/Orig.)

Published: October 2023

Bildliche Darstellungen ermöglichen Schüler*innen Sachverhalte zu erfassen und mithilfe dieser Darstellungen fachbezogen miteinander über Fachinhalte zu kommunizieren. Die Qualität der Bilder und die didaktische Funktion ist dabei besonders zu beachten, da Bilder nicht automatisch bzw. direkt und unproblematisch einen Lernprozess unterstützen. Auf Basis einer Schulbuchanalyse wurden Bildeigenschaften in Schulbüchern des Sachunterrichts mittels Kategorienkatalog herausgearbeitet und bewertet, um darauf aufbauend den Wissenserwerb durch Bilder in einem (sensiblen) (sprach-)fachlichen Verständnis im naturwissenschaftlich-orientierten Sachunterricht eruieren zu können. Der vorliegende Artikel gibt einen Überblick zum entwickelten Kategorienkatalog und spezifiziert die Analysekategorie Funktionalität. (DIPF/Orig.)
Schriftsprachliche Zugänge im Sachunterricht – Sichtweisen von Lehrpersonen auf Sachtexte
Authors: Wolken Svenja
Published: October 2023

Sachtexte können als Gegenstand aus unterschiedlichen Perspektiven betrachtet werden. Aufgrund ihrer Abgrenzung zu fiktionalen bzw. literarischen Texten bietet insbesondere die Textlinguistik als eine sprachwissenschaftliche Teildisziplin zentrale Bezüge für eine definitorische Auseinandersetzung. Neben textinternen Merkmalen wie die sprachliche Erscheinungsform sind ebenfalls textexterne Merkmale wie der situative Kontext, das Thema bzw. der Inhalt und die Funktion relevant. Somit wird der schulische Kommunikationsbereich innerhalb eines Fachunterrichts zur relevanten Größe, um einen Text zu beschreiben. Diese vielfältigen Dimensionen bilden die Grundlage dafür, die Eignung von Sachtexten für das Fach Sachunterricht zu diskutieren und zu bewerten. Lehrpersonen nehmen Einfluss auf die Gestaltung schriftsprachlicher Zugänge durch die Auswahl textbasierter Medien, weshalb ihre Sichtweise auf Sachtexte im Kontext von Sachunterricht von Belang ist.

Published: October 2023

Im permanenten Krisenerleben der Moderne wird die Überforderung der Gesellschaft mit sich selbst sichtbar. Da verspricht Gemeinschaft – verstanden als grundsätzlich positiv besetzte Vorstellung einer idealen sozialen Einheit – Entlastung, Geborgenheit und Sicherheit. Das lässt sich auch auf die Vorstellung einer schulischen Klassengemeinschaft übertragen. Was aber ist das Gemeinsame, das einer jener zugrunde liegt? Wie wird was für eine Gemeinschaft hergestellt? Und inwiefern lässt sich dabei von einer nachhaltigen Gemeinschaft(-sbildung) sprechen? Die Autor*innen erörtern diese Fragen am Beispiel des Klassenrats als pädagogisches Medium der Gemeinschaftsbildung. Dafür richten sie ihren Blick zunächst auf grundlegende Verständnisse (Kapitel 1) und zeichnen empirisch den Vollzug und die Konstitution von Gemeinsamem im Klassenrat nach (Kapitel 2). Abschließend stellen sie das sich darin zeigende Verständnis nachhaltiger Gemeinschaftsbildung im schulischen Kontext dar und beleuchten dessen Implikationen (Kapitel 3). (DIPF/Orig.)
Abu Shamah, Historian of the Crusades 599-665 AH / 1202-1267 AD
Authors: Sarayrah Baker Mohammed , AL Rwaidi Mahmoud Mohammed
Published: October 2023

The study examines the life and scientific career of Abu Shamah, the role of his father in his education, and the legal school that he followed. Abu Shamah was known as the most important of the sheikhs and students of his legal school, and he avoided senior positions in the state and remained in teaching positions. Abu Shama recorded the history of the Crusades from 491 AH / 1098 AD until 665 AH / 1267 AD, the year of his death. This study focuses on his approach to the history of the Crusades, the image of the Franks he had through the texts he cited, and the sources from which he derived his information. The study shows that Abu Shamah provided an abundance of information about the Crusades. To give a clear and complete picture of the content of these narratives, it is necessary to subject them to quantitative study that breaks up the historical material and arranges and analyizes it in a way that enables the study to reach accurate results, identical to the information provideed by other historical sources, and to show the political conditions of the Muslim countries, and the results of the campaigns launched by the Franks.

يناقش البحثُ اسمَ علمٍ يَرِدُ في نقش عربي يرجعُ إلى أوائل القرن الثاني الهجري، اكتُشف في وادي شيرة بجنوب الأردن في ثمانينيات القرن العشرين. وعلى الرَّغم من أنَّ عددًا من الباحثين اشتغل بالنقش، فإنهم لم يولوا اسمَ صاحبه عنايةً كافية. يخلصُ البحثُ بعد مناقشة الاحتمالات المختلفة لشكل الاسم إلى أنَّ لفظه -على الأرجح- هو "عبد العَلا"، ويلفت النظر إلى أنَّ هذا الاسم يَرِدُ للمرَّة الأولى ضمنَ أسماء العلم العربيَّة، غيرَ أنَّ أهم ما يلفت النظر في الاسم أنه يصف الله -سبحانه وتعالى- باسم لم يرد سابقًا ضمن القوائم المتَّفق عليها لأسماء الله الحُسنى؛ لِذا يناقش البحثُ هذه الأسماءَ والأحاديثَ والآراءَ الواردة بشأنها في المصادر الإسلاميَّة؛ سعيًا إلى فهم المعطيات الدينيَّة التي أتاحت ظهورَ هذا الاسم خلافًا لما هو متوقع. وعليه، فقد خلصَ البحثُ إلى أنَّ استخدام هذا الاسم يرجع، في المحلِّ الأول، إلى الموقف المتساهل الذي أبداه الفقهاءُ تجاه تقنين أسماء الله الحُسنى، معتبرين إيَّاها قائمة "مفتوحة" من الألقاب، لا كبيرَ حرج في الإضافة إليها. وقد استُخدم هذا الاسم أيضًا لشبهه بأسماء أخرى من أسماء الله الحُسنى مشتقة من الفعل "علا"، مثل "عبد العَلي".
Towards a better conceptual understanding of how students learn business research methods
Authors: Kueenzi Stefan
Published: October 2023

Business graduates need a solid understanding of research methods, for example to make decisions based on empirical evidence. As a meta-analytic review by Earley (2014) shows, we are lacking sufficient empirical information on what influences research methods education and a solid conceptual understanding of what these influential factors mean for student learning. This research begins to fill this gap by presenting results from interviewing 18 lecturers in undergraduate programmes in Business and Management. The findings are linked to Paul R. Pintrich’s framework for assessing motivation and self-regulated learning (Pintrich, 2004). The major findings include that aspects related to why students are doing specific learning tasks and the concept of self-efficacy play important roles. Other themes of the meta-analytic review by Earley are discussed, for example students’ anxiety, poor attitudes, and misconceptions about research. The study concludes by making recommendations for future research.

Published: October 2023

This is a case of a rare tracheal tumor, in a 45year old male farmer who presented with recurrent dyspnea for four years, initially misdiagnosed as asthma. The patient experienced worsening symptoms, including cough, hemoptysis, weight loss, and respiratory failure. Imaging and bronchoscopy revealed a tracheal mass, later identified as leiomyoma. The patient underwent tumor resection via rigid bronchoscopy, resulting in successful removal and tracheal recanalization. Postoperatively, the patient showed improvement, and follow-up examinations confirmed resolution of symptoms and absence of tumors, such as leiomyoma, are rare, often causing airway obstructions. Treatment approaches vary, including surgical resection and endoscopic techniques. In the case of wide-based tumors, surgical intervention is recommended to reduce recurrence risks. Anesthesia management is crucial due to potential airway compromise during the procedure. Although recurrence rates for leiomyoma are unknown, incomplete bronchoscopic resection has been associated with reoccurrence, necessitating surgery and carinal reconstruction.
AFINAL, O QUE É A LGBTFOBIA?
Authors: Coelho Gilson Gomes , Desidério Plábio Marcos Martins , Rocha Luisa Pereira
Published: October 2023

Este estudo visa a provocar reflexões em torno da LGBTfobia enquanto conceito, associado socialmente ao estigma de pessoas LGBT, por se encontrarem fora dos contornos institucionais sacralizados historicamente pelo cissexismo, referente ao gênero e à orientação sexual. Nesta reflexão, a LGBTfobia é conceitualmente entendida como dispositivo dentro do mesmo prisma de Michel Foucault, dada a existência intencional de ações e mecanismos de dominação pelo aparato das instituições, mesmo que de forma velada. Tais práticas intencionais culminam na produção de múltiplas formas de violência, desumanização e morte — de quem não adere ao sistema sexo-gênero vigente. Sendo assim, ao se tratar de um dispositivo, conclui-se que as vulnerabilidades decorrentes da LGBTfobia não devem ser encaradas como uma questão individual e nem análogas ao racismo, pois isso reforça o apagamento de particularidades estruturais, bem como as gradações de enfrentamentos cotidianos da população LGBT.

Authors: Li Wei , Li Guoyan , Kamarthi Sagar
Published: October 2023

The increasing complexity of a vehicle's digital architecture has created new opportunities to revolutionize the maintenance paradigm. The Artificial Intelligence (AI) assisted maintenance system is a promising solution to enhance efficiency and reduce costs. This review paper studies the research trends in AI-assisted vehicle maintenance via keyword co-occurrence network (KCN) analysis. The KCN methodology is applied to systematically analyze the keywords extracted from 3153 peer-reviewed papers published between 2011 and 2022. The network metrics and trend analysis uncovered important knowledge components and structure of the research field covering AI applications for vehicle maintenance. The emerging and declining research trends in AI models and vehicle maintenance application scenarios were identified through trend visualizations. In summary, this review paper provides a comprehensive high-level overview of AI-assisted vehicle maintenance. It serves as a valuable resource for researchers and practitioners in the automotive industry. This paper also highlights potential research opportunities, limitations, and challenges related to AI-assisted vehicle maintenance.

Published: October 2023

Risk factors are an inherent component of construction projects, and sometimes, it is difficult to completely eliminate these risks without proper management. This research focused on investigating cost-related risk indicators influencing the performance of construction projects in insurgency-affected areas such as Maiduguri. The assessment employed the Relative Importance Index (RII) and Exploratory Factor Analysis (EFA) to gauge the likelihood of these risks. Data was collected via a questionnaire from construction professionals, including clients, consultants, contractors, and subcontractors. The results analyzed through statistical software revealed that key drivers of cost-related risks were safety and environmental factors, physical threats, disasters, force majeure events, and economic risk factors. The top five most probable risks included costs related to insurgency damages, financial limitations due to insurgency, oversights caused by the insurgency, price increases due to attacks, and labour shortages. Conversely, risks related to cash flow issues and project cost estimation errors were less common. The findings suggest that professionals who consider these specific risk factors when devising risk management strategies can enhance the accuracy of their risk assessments and cost projections.
Fast Phase Recognition of Mechanical Helical Phased Array Antenna Element Based on Line-Scan Machine Vision
Authors: Guo Chang , Qiu Song , Ni Tailai , Wang Bangji , Liu Qingxiang
Published: October 2023

Mechanical helical phased array antenna (HPAA) realizes microwave beam directing by mechanically rotating the helical antenna element. Measuring and calibrating the phase of the HPAA, which can be simplified to measure and calibrate the phase of each helical antenna element, is significant important to evaluate the antenna performance. To realise fast phase measurement and calibration of element antenna, this paper proposed a line-scan machine vision (MV) strategy. A prototype MV system combining a line-scan camera and a guide rail structure to acquire the image of helical antenna element is designed and proposed. Phase recognition algorithm based on deep-learning You Only Look Once v8 (YOLOv8) and Pixel Difference Networks (PiDiNet) with Field of View Error (FOVE) minimization, is proposed to conduct element detection and edge detection, and further to determine of the angular state, which quantifies the phase of the helical antenna element. Statistical analysis of experimental results on a 5×8 test antenna array shows that ±1° phase recognition accuracy can be achieved within 43 seconds to demonstrate the accuracy and efficiency of our proposed method. Moreover, measurement uncertainty of the proposed approach is analyzed that can be quantified with a normal distribution to show 83% of recognised result errors falls with 1° to demonstrate its stability and reliability.

Published: October 2023

Navigational systems, the heart of maritime oper- ations, face escalating cybersecurity risks due to their system of systems nature and reliance on diverse suppliers. Amid concerns about supply chain attacks and insider threats, the potential for malicious radar image injections, including Inverse Synthetic Aperture Radar (ISAR) images, is emerging. Such manipulations can critically undermine navigational integrity through the generation of decoy targets, the strategic relocation of existing ones, and the effective concealment of additional targets. We have identified where an Advanced Persistent Threat (APT) could be concealed within the processing chain of a modern radar system. This study demonstrates the potential of APTs to exploit Generative Adversarial Networks (GANs) for the creation of deceptive ISAR images, thereby spotlighting this previously unexplored threat vector. Our findings offer novel insights into bolstering maritime cybersecurity in an increasingly AI-dominated landscape.

Published: October 2023

The World Health Organization (WHO) has instituted the Caregiver Skill Training (CST) program to assist families with children diagnosed with Autism Spectrum Disorder. The Joint Engagement Rating Inventory (JERI) protocol evaluates participants' engagement levels within the CST initiative. Traditionally, JERI assessments rely on retrospective video analysis conducted by qualified professionals, thus incurring substantial labor costs. This study aims to augment the evaluation efficiency of the Expressive Language Level and Use (EXLA) criterion within JERI, striving for consistency with human-based scoring. To this end, we introduce a multimodal behavioral signal-processing framework designed to analyze both child and caregiver behaviors, thereby offering grading recommendations as an alternative to medical professional input. Initially, raw audio and video signals are segmented into concise intervals via voice activity detection, speaker diarization and speaker age classification, serving the dual purpose of eliminating non-speech content and tagging each segment with its respective speaker. Subsequently, we extract an array of audio-visual features, encompassing our proposed interpretable, hand-crafted textual features, end-to-end audio embeddings and end-to-end video embeddings. Finally, these features are fused at the feature level to train a linear regression model aimed at predicting the EXLA scores. Our framework has been evaluated on the largest in-the-wild database currently available under the CST program. Experimental results indicate that the proposed system achieves a Pearson Correlation Coefficient of 0.713 against the expert ratings, evidencing performance comparable to that of human experts. This approach not only provides immediate feedback for CST participants but also optimizes resource allocation in less developed regions.
Are rapid releases developed rapidly?
Authors: Pinto Felipe , Gresta Paulino Murta Leonardo
Published: October 2023

Agile development uses rapid releases to deliver features early and often to users, enabling them to provide quick feedback about the software. We observed that relevant projects, such as Firefox and Chrome, adopt rapid release, but in some cases, the development duration takes longer than the release cycle. This work analyzed whether other projects adopting rapid release also present similar behavior. We analyzed an open-source corpus comprising 1,039 relevant open-source projects, with 13,102 rapid releases and 7,071 traditional releases (without counting the patches), totaling 20,173 releases with 3,167,563 commits. We compared rapid and traditional releases to understand changes regarding the development duration, the development start delay, and the percentage of percentage of commits in the release cycle. We discovered that, in most cases, the development duration of rapid releases is higher than its release cycle, meaning that most projects delivering rapid releases employ parallel release development. However, on average, the amount of work done in parallel has a small impact on the release development. Moreover, the development of rapid releases starts early and without delays. Traditional releases' development is generally preceded by a pause, probably due to patch development and release stabilization. Therefore, our results suggest that projects that intend to adopt rapid release do not necessarily need to reduce the development duration. The projects may start the release development early and manage parallel release development to achieve a rapid release cycle.

Optical Networks Automation Overview: A Survey
Authors: Cruzes Sergio
Published: October 2023

Innovations in optical networks created new technological challenges as routing and spectrum allocation (RSA) problem, fragmented spectrum, the need for rapid and efficient channel restoration, and put pressure on the operation and maintenance. With a lot of lots of variables or knobs to adjust, it is crucial to improve the automation as traditional algorithms are not able to handle the network efficiently. So, this requires sensors, network abstraction, actuators and SDN (Software Defined Networking) in order to run algorithms on top, control, manage the network and make decisions. In addition to this, there are the requirements for low-margin systems and probabilistic shaping. So, machine learning (ML) provides a collection of techniques to adapt to this dynamic and flexible environment and provide a network that learn from experience, optimize and make the networks agile, robust, dynamic, and smarter. At the same time, network automation together with machine learning may cause an explosion in power consumption, making this solution costly, inefficient and not sustainable.  
A Dynamic Vacancy-Applicant Matching System Considering Locking Periods and Break-up Penalties
Authors: Hou Shixuan
Published: October 2023

Online labor markets, which allow applicants to seek suitable jobs anytime and anywhere, offer greater flexibility than traditional offline labor markets. This paper investigates a dynamic matching system that assigns appropriate applicants to appropriate vacancies in the condition that the arrivals of applicants and vacancies are uncertain. The objective of the matching system is to obtain a stable matching solution for both applicants and vacancies. To this aim, we propose three dynamic matching algorithms for three different market settings. The theoretical proof of the stability of each matching algorithm is given, and we conduct a series of computational experiments to verify the effectiveness and efficiency of the proposed matching algorithms. The results indicate that the algorithms can be an efficient and effective tool for recruitment management in today’s active and internet-based labor markets to reduce the administrative workload of human resource departments and produce stable job allocations.
EDA-graph: Graph Signal Processing of Electrodermal Activity for Emotional States Detection

Published: October 2023

The continuous detection of emotional states has many applications in mental health, marketing, human-computer interaction, and assistive robotics. Electrodermal activity (EDA), a signal modulated by sympathetic nervous system activity, provides continuous insight into emotional states. However, EDA possesses intricate nonstationary and nonlinear characteristics, making the extraction of emotion-relevant information challenging. We propose a novel graph signal processing (GSP) approach to model EDA signals as graphical networks, termed EDA-graph. The GSP leverages graph theory concepts to capture complex relationships in time-series data. To test the usefulness of EDA-graphs to detect emotions, we processed EDA recordings from the CASE emotion dataset using GSP by quantizing and linking values based on the Euclidean distance between the nearest neighbors. From these EDA-graphs, we computed the features of graph analysis, including total load centrality (TLC), total harmonic centrality (THC), number of cliques (NoC), diameter, and graph radius, and compared those features with features obtained using traditional EDA processing techniques. EDA-graph features encompassing TLC, THC, NoC, diameter, and radius demonstrated significant differences (p<0.05) between five emotional states (Neutral, Amused, Bored, Relaxed, and Scared). Using machine learning models for classifying emotional states evaluated using leave-one-subject-out cross-validation, we achieved a five-class F1 score of up to 0.68.

Published: October 2023

A novel metasurface reflector unit cell based on two coupled resonators is proposed and demonstrated for real-time reconfigurable beamforming in the X-band (8-12 GHz). The unit cell is composed of a split-ring resonator (SRR) with tunable capacitance and a dipole-ring resonator (DRR) with tunable resistance, whose collective variations allow for control over the complex reflectance at a desired frequency. To gain physical insight into its working mechanism, the proposed unit cell is modeled as a coupled Lorentz oscillator using the surface susceptibility description of the unit cell. Thereafter, a metasurface reflector based on the proposed unit cell is demonstrated in full-wave simulations to achieve various beamforming examples, such as beam-steering, side-lobe level control, beam-steering with amplitude control, and multi-beam patterns, from a single normally incident plane wave excitation. Three metasurface reflectors are fabricated to experimentally demonstrate the proposed concept; the first is based on a SRR with a varactor diode, the second is based on a DRR with a PIN diode, and the third is based on the proposed coupled SRR-DRR configuration with both varactor and PIN diodes, for simultaneous magnitude and phase control. The metasurface reflector based on the coupled resonator unit cell is experimentally demonstrated to achieve versatile beam transformations including beam-steering with amplitude control and multi-beam patterns.
