Ιστορική εκπαίδευση και χρήση του διαδικτύου: μία διδακτική πρόταση εστιασμένη στις δομικές ιστορικές έννοιες
Authors: Καραμανώλη Ελένη
Published: October 2022

The introduction of the Internet in the teaching of History was set in the service of a “New History” in school aiming the historical thinking. Learning through Internet means the collection, evaluation, correlation and handling of the historical information, which is judged absolutely necessary for all new teaching and learning strategies. This History teaching deals with interactive learning in a wide open electronic environment where the teacher takes up a consulting-guiding role. The web and the increasing number of educational software applications consist a powerful tool in the hands of the teacher and contribute in the methodological historical knowledge through searching, gathering, and managing data, the exporting of deductions and finally the sharing of the digital progress. The electronic tools the students will use will assist them handle and conceptualize the structural second order historical concepts such as causation, continuity, change, space, time and empathy. At the beginning of the 21st century students need to have historical and digital literacy in order to deal with the requirements of every day life in a critical way.

Η γλωσσική αγωγή σε μεταβατικό στάδιο: νεότερες εξελίξεις και προοπτικές στο πλαίσιο του Νέου Σχολείου
Authors: Χρύσου Μάριος
Published: October 2022

Es ist eine Tatsache, dass das institutionelle Fremdsprachenlernen einen besonderen Stellenwert vor dem Hintergrund des lebenslangen Lernens und der Mehrsprachigkeit hat. Zurzeit befindet es sich in Griechenland in einer Übergangsphase. Ziel dieses Beitrags ist, Haltungen und aktuelle Entwicklungen im Bereich des Fremdsprachenlernens hierzulande zu skizzieren. Zunächst werden das traditionelle Verständnis von Lehren und Lernen beschrieben, das dem schulischen Fremdsprachenlernen zu Grunde liegt, und dem pädagogischen Verständnis von Lernen im konstruktivistischen Ansatz gegenübergestellt. Anschließend werden am Beispiel des neuen Gemeinsamen Rahmencurriculums für die Fremdsprachen die bildungspolitischen Reformen des schulischen Fremdsprachenlernens dargestellt, die vom griechischen Kultusministerium im Rahmen des Projekts „Neue Schule (Schule des 21. Jahrhunderts)“ vorangetrieben werden. Schließlich werden die Herausforderungen kritisch beleuchtet, die in der Umsetzung des Gemeinsamen Rahmencurriculums für die Fremdsprachen in der Unterrichtspraxis liegen, und die Perspektiven für die Entwicklung des institutionellen Fremdsprachenlernens in Griechenland umrissen.
Γνωστικές πτυχές της προφορικής παιδικής ποίησης στο πλαίσιο της νεοελληνικής παραδοσιακής κοινωνίας
Authors: Κόκκινος Δημήτρης
Published: October 2022

Στο παρόν άρθρο εξετάζουμε τον γνωστικό χαρακτήρα της προφορικής ποίησης των παιδιών στα πλαίσια της νεοελληνικής παραδοσιακής κοινωνίας. Η προφορική ποίηση αξιοποιώντας μια σειρά από μνημοτεχνικούς μηχανισμούς λειτουργούσε για πολλούς αιώνες ως φορέας γνώσεων, ιδεών και πρακτικών/τεχνικών. Για τον λόγο αυτό αξιοποιήθηκε στις προφορικές παραδοσιακές κοινωνίες ως  ένα άτυπο παιδαγωγικό μέσο. Μέσω αυτής το παιδί γίνεται μέτοχος σε μια πολυσύνθετη μαθητεία που καλύπτει παράλληλα την γλωσσική, την αισθητική και την γνωστική καλλιέργεια. Χαρακτηριστικό παράδειγμα αποτελεί η παιδική ποίηση της νεοελληνικής προφορικής παράδοσης. Σημαντική διάσταση καταλαμβάνει ο γνωστικός χαρακτήρας ο οποίος βοηθά το παιδί να συγκρατήσει τις απαραίτητες γνώσεις για να μπορέσει να ανταποκριθεί στις ανάγκες της ζωής. Μερικά από τα πιο βασικά χαρακτηριστικά γνωρίσματα του γνωστικού χαρακτήρα της παραδοσιακής παιδικής ποίησης είναι ότι βασίζεται σε  ένα αισθησιοκρατικό, φυσιοκρατικό και παράλληλα σε ένα εμπειρικό και βιωματικό πνεύμα. Πίσω από το γνωστικό αυτό χαρακτήρα μπορεί να αναγνωρίσει κανείς στοιχεία μιας γενικότερης παραδοσιακής παιδαγωγικής με παγκόσμιες και διαχρονικές προεκτάσεις.
Η πολιτική αυτοαντίληψη των νέων της Ευρώπης και οι νέες μορφές νεανικής πολιτι-κής συμμετοχής: Εμπειρική προσέγγιση
Authors: Παπαοικονόμου Αντώνης

Η εργασία αυτή παρουσιάζει μία έρευνα που εκπονήθηκε στα πλαίσια του προγράμματος Europe on the Edge: Redefining politics of the 21st century από το μη κυβερνητικό και μη κερδοσκοπικό εκπαιδευτικό ίδρυμα Sharing Perspectives. Σκοπός της έρευνας είναι ο προσδιορισμός της πολιτικής αυτοαντίληψης των Ευρωπαίων νέων όσον αφορά την πολιτική συμμετοχή και τις δημοκρατικές αξίες αλλά και της διερεύνησης του βαθμού χρήσης των κοινωνικών δικτύων για την πολιτική έκφραση τους. Τα αποτελέσματα έδειξαν ότι παρόλο που η ευρεία αντίληψη είναι αυτής της ριζοσπαστικής αντιμετώπισης των θεσμών εκ μέρους των νεανικών ομάδων, η πλειοψηφία τους πιστεύει στις παραδοσιακές μορφές πολιτικής συμμετοχής και της συμβατικής συμμόρφωσης στις επιταγές των νόμων. Επίσης παρατηρήθηκε ένας δισταγμός στη χρήση των κοινωνικών δικτύων για την πολιτική έκφραση, γεγονός που αποδεικνύει μία διαφαινόμενη ανωριμότητα εκ μέρους των Ευρωπαίων νέων σε ό, τι αφορά τις νέες μορφές πολιτικής συμμετοχής.
Η Κατανεμημένη Γνώση (Distributed Cognition) στο σχολείο: Θεωρία και Πράξη
Authors: Μπιτσάνη Αναστασία
Published: October 2022

Σε τελευταίες έρευνες παρατηρήθηκε ότι σε καταστάσεις αντιμετώπισης καθημερινών προβλημάτων οι άνθρωποι εμφανίζονται να σκέπτονται μαζί με τους άλλους και με τη βοήθεια εργαλείων και μέσων που ο πολιτισμός τους τούς προμηθεύει και επομένως ότι οι γνώσεις είναι κατανεμημένες (distributed). Η γνώση κατανέμεται μέσω  των εργαλείων/πόρων που υπάρχουν στο περιβάλλον και αποτελούν τα μέσα με τα οποία οι μαθητές αποκτούν πρόσβαση και κατανοούν το περιβάλλον. Επομένως, η μάθηση αποτελεί έναν κύκλο γνωστικής ανάπτυξης που επέρχεται ως αποτέλεσμα των σχέσεων μεταξύ ατόμων και άλλων δικτύων γνώσης. Στο σχολείο μπορεί να αξιοποιηθεί με επιτυχία η δυναμική των ΤΠΕ σε συνδυασμό με τους πνευματικούς πόρους των μαθητών, με τους κοινωνικούς, συμβολικούς και φυσικούς πόρους, μέσα σε ένα κοινωνικά δομημένο μαθησιακό περιβάλλον.  Ο ρόλος του δασκάλου αναδεικνύεται ως βασικός, καθώς δίδεται έμφαση στον ενωτικό ρόλο του, όχι μόνο ως «κοινωνικού πόρου», αλλά ως του ανθρώπου που διαμεσολαβεί στη συνολική διαδικασία μάθησης των μαθητών.

Kas see on sama mis too? Hinnangukatse eesti keele demonstratiivpronoomenite ja demonstratiivadverbidega
Authors: Reile Maria , Averin Kristiina , Põldver Nele
Published: October 2022

Eesti keeles on kaks demonstratiivpronoomenite süsteemi: üheliikmeline, kus kasutatakse demonstratiivpronoomenit seedistantsneutraalselt, ja kaheliikmeline, kus see viitab kõneleja lähedal ning too kaugel olevale referendile. Mõlemas süsteemis lisatakse demonstratiivpronoomenile sageli demonstratiivadverb (nt see siin). Süsteemi valik näib olevat seotud keelekõneleja päritoluga – Lõuna-Eesti päritolu kõnelejad kasutavad kaheliikmelist, Põhja-Eesti päritolu üheliikmelist süsteemi. Uurimuses keskendume kahe demonstratiiviga fraasidele (nt see siin), püstitades kaks küsimust. Esiteks, milline on keelekõnelejate enda arvamus selle kohta, milliseid demonstratiive millises ruumilises olukorras nad kasutaksid. Teiseks, kas see, kuidas keelekõneleja arvab end demonstratiive sisaldavaid lauseid kasutavat kattub vastavate lausete tõlgendamisega samas olukorras. Viisime läbi hinnangukatse, mille tulemusi võrdleme varem avaldatud tõlgenduskatse tulemustega. Mõlema katse andmed koguti järjestikuselt ning samadelt katseisikutelt. Hinnangukatse näitas, et lõunaeestlased hindasid too’d sisaldavate lausete ütlemist tõenäolisemaks kui põhjaeestlased. See’d sisaldavate lausete puhul päritolu hinnanguid ei eristanud. Sarnaselt tõlgenduskatsega osutus ka hinnangukatses oluliseks referendi kaugus, kuid visuaalne esilduvus andis erinevaid tulemusi, viidates kauguse teguri kesksusele ning esilduvuse perifeersusele demonstratiivide tähenduses.

Abstract. Maria Reile, Kristiina Averin, Nele Põldver: Does see ‘this’ equal too ‘that’? Rating task with Estonian demonstrative pronouns and demonstrative adverbs. Estonian employs two demonstrative pronoun systems – a one-way system (used in North Estonia) where the demonstrative pronoun see is distance neutral, and a two-way system (in South Estonia) where see is the proximal and toothe distal demonstrative pronoun. In both systems, demonstrative adverbs are often added to demonstrative pronouns, forming two-demonstrative phrases (e.g., see siin). We conducted a rating study to investigate these phrases, asking which demonstratives the speakers would use in which spatial settings. In addition, we compared these results with a previously published interpretation study to see whether the speakers’ opinions to use or not use certain demonstratives match their interpretations of these demonstratives. The rating study showed that South Estonians would use the demonstrative toomore likely as compared to North Estonians while origin had no effect on using the demonstrative see. Both experiments showed a similar effect of distance on demonstrative use, but not visual salience.

Use of Unmanned Aerial Vehicles (UAVs) for Structural Health Monitoring (SHM) has become commonplace across civil and energy generation applications with hazardous or time-consuming inspection processes. Expanding upon surface screening offered by non-contact remote visual inspection UAVs, systems are now beginning to incorporate contact-based Non-Destructive Evaluation (NDE) transducers to detect and monitor incipient sub-surface flaws. However, challenges to environmental interaction using conventional multirotor platform dynamics amid aerodynamic disturbances have frustrated efforts for stable and repeatable sensor placement. Herein, two distinct UAV systems are evaluated as a means to overcome these challenges. The first utilizes vectored thrust with a tri-copter layout. It may dynamically reorient dual-axis tilting propellers to directly effect interaction force and deploy drycoupled ultrasonic thickness measurement across omnidirectional targets. In static point and rolling scan measurement, laboratory tests demonstrate mean absolute error below 0.1 mm and 0.3 mm, respectively. The second UAV uses rigidly affixed multidirectional propellers to reverse and redirect its net thrust. Landing atop cylindrical structures it may crawl around their circumference, supporting itself without magnetic or vacuum adhesion. Arbitrary static position is maintained to within a mean deviation of 0.7 mm. Lastly, comparative discussion of each system informs strategies for further development of contact-based aerial SHM and its adoption to industrial practice.

Published: October 2022

Health management methodologies for condition-based maintenance are often developed using sensor data collected during experimental tests. Most tests performed in laboratories focus on a coupon level or flat panels, while structural component testing is less commonly seen. As researchers, we often consider our experimental tests to be representative of a structure in a final application and consider the developed methodologies to be transferrable to these real-life structures. Yet, structures in their final applications such as wind turbines or aircraft are often larger, more complex, might contain various assembly details, and are loaded in complex conditions. These factors might influence the performance of developed diagnostic and prognostic methodologies and should therefore not be ignored. In our work, we consider the aspects of upscaling structural health monitoring (SHM) methodologies for stiffened composite panels with the design of the panels inspired by an aircraft wing structure. For this, we examine two levels of panels, namely a single- and multi-stiffener composite panel, where we consider the single-stiffener panel to be a representative lower-level version of the multi-stiffener panel. Multiple SHM sensors (acoustic emission, Lamb waves, strain sensing) were installed on both composite panels to monitor damage propagation during testing. We identify and analyse challenges and further discuss considerations that must be taken during upscaling of diagnostics and prognostics, and with that, aid in the development of health management methodologies for condition-based maintenance.

DEEP LEARNING FRAMEWORK FOR POST-HAZARD CONDITION MONITORING OF NUCLEAR SAFETY SYSTEMS
Authors: SANDHU KAUR HARLEEN , SRIKANTH BODDA SARAN , GUPTA ABHINAV
Published: October 2022

A novel approach is presented to conduct data-driven condition assessment in nuclear safety systems with the aid of deep learning. With the resurgence of nuclear energy due to the ever-increasing demand for electricity and carbon free power generation, ensuring safe operations at nuclear facilities is important. Nuclear safety systems, such as equipment-piping, undergo aging and subsequent degradation due to flow-accelerated erosion and corrosion. Conventional non-destructive techniques implemented during plant outages can take weeks and months to scan all the systems in their entirety. Continuous condition monitoring of such systems would result in lowering the maintenance costs along with extending the operating lifetime for a nuclear power plant. Additionally, the proposed framework should be able to detect minor degradation caused due to aging of nuclear facilities. Uncertainty in the degradation severity levels is also incorporated in the design of the condition assessment methodology. In this paper, the use of artificial intelligence (AI) algorithms as well as vibration-based health monitoring for degradation detection has been demonstrated. A simple equipment-piping system subjected to an external hazard, such as an earthquake, is selected as an application case study. A proof-of-concept is presented wherein the proposed framework utilizes the data collected from sensors to generate a machine learning data repository, demonstrates pattern recognition and feature extraction, explores the design of an artificial neural network (ANN), and develops a sensor placement strategy. The effectiveness of the proposed framework is demonstrated on a realistic primary safety system of a two-loop reactor plant. It is shown that the proposed post-hazard condition monitoring framework is able to detect degraded locations along with the severity levels with high degree of accuracy.

A multi-dimensional model to the digital maturity life-cycle for SMEs
Authors: Sándor Ágnes , Gubán Ákos
Published: October 2022

As companies try to maintain and strengthen their competitive advantage, they should be aware of the level of their digital maturity. The study aims to present a methodology that helps to determine the position of a small and medium-sized enterprise in the digital maturity life-cycle. This is performed on the basis of maturity and digital maturity models, and company growth theories. A number of studies and models have been prepared to determine digital maturity on the basis of various sectoral criteria, but these are all one-dimensional. The study therefore proposes a multi-dimensional model for determining the digital maturity life-cycle of small and medium-sized enterprises that takes into account companies’ digital maturity, the IT intensity of various sectors and their organizational characteristics. The model defines five maturity levels together with their relevant characteristics, classified into three levels in terms of data-information. It can help small and medium-sized enterprises adopt more accurate decisions regarding areas in need of development.
Executives' role in digital transformation
Authors: López-Muñoz José Fernando , Escribá-Esteve Alejandro
Published: October 2022

This conceptual paper revisits and updates the concept of top management support (TMS), which has been the long-established rationale for explaining the role of top managers in digitalization activities. In our view, the concept of TMS is grounded in technological determinism, accounts for attitudinal and behavioral aspects that appear to be little more than exhortation and accepts the occasional responsibility of top managers in technology management. We consider both the crucial role that top managers may play in the digitalization process and the fact that digital technologies have become pervasive in today’s organizations. Then, we develop a model by which top managers and digital technologies are cooperatively involved for digitalization. For that, we have looked through the theoretical lens of imbrication and attention perspectives to reconstruct the role of top managers in the digital transformation process. In our view, each imbrication layer can be viewed as a process where top managers form beliefs to act on digital opportunities for strategic action. Specifically, our model provides insights into how executives’ characteristics and social processes impact the likelihood of forming either beliefs about radical or incremental opportunities requiring strategic action. Additionally, we offer several hypotheses that enrich our knowledge of the relationship between top managers and the digitalization process.
Value Capture in the Face of Known and Unknown Unknowns
Authors: Bryan Kevin A. , Ryall Michael D. , Schipper Burkhard C.
Published: October 2022

A large theoretical literature on value capture uses cooperative games under complete information to study how and why firms earn supernormal profits. However, firms often have different information, beliefs, or creative foresight. We extend value capture theory to incomplete information (“known unknowns”) or unawareness (“unknown unknowns”) and illustrate some conceptual issues with that extension. Using the case study of Cirque du Soleil, we show how an entrepreneurial firm can profit even when it does not contribute materially to value creation. In a case study of Apple iTunes, we show how value capture depends quantitatively on the beliefs of other firms.

Cinsiyet Hoşnutsuzluğu Belirtileri Gösteren Çocuklarda Demografik ve Klinik Özellikler: Bir Türkiye Örneklemi
Authors: GÜNEŞ Hatice , KAYAALP M. Levent
Published: October 2022

Objective: In this study, we aim to describe the demographic and clinical characteristics and psychological functioning of children with gender dysphoria (GD) symptoms aged between 3-12 years.
Material and Methods: The study group included 20 children (17 males, 3 females; mean age 6.63±2.43 years) with GD symptoms. A sociodemographic data form was used to collect data with regards to demographic and clinical characteristics, and pre- peri-and postnatal features. The Child Behavior Checklist (CBCL) is used to assess behavioral and emotional problems in the child.
Results: The boy/girl ratio in the study group was 5.66. The mean age at onset of gender-nonconforming behaviors was 2.85±1.17 years and the mean age of admission to our clinic was 5.82±2.27 years. 20% of the mothers reported a preference for an opposite-sex child prior to conception; 20 % of the mothers reported prenatal stress, 20% of the mothers had prenatal and 25% had postnatal depressive symptoms. There was a risk of miscarriage in 10% of children and 25% were born prematurely. 55% of our study sample exceeded the clinical threshold for internalizing problems and 40% exceeded the clinical threshold for externalizing problems in CBCL ratings.
Conclusion: There were more prepubertal boys than girls referred for GD symptoms and the age at referral was younger compared to western countries. In addition, findings of this study indicate that children with GD have poorer psychological functioning possibly due to social intolerance for cross-gender behaviors and/or interests alongside the GD per se.

Wandering behaviour and elopement in a person with dementia in a residential care setting: a reflective case study
Authors: Duffy Anita , Dalton Chris , Connolly Michael
Published: October 2022

This article reports on a fictional case study focusing on a person with dementia with a history of wandering behaviour, who was admitted to a residential care setting for 2 weeks of respite care. Caring for people with behavioural and psychological symptoms of dementia is complex. It is imperative that gerontology nurses have a sound knowledge of dementia in order to provide person-centred, safe, integrated, high-quality and appropriate care. Furthermore, gerontology nurses are in a position to support people with dementia and their carers by undertaking a comprehensive assessment of the person's needs to advise on possible and appropriate solutions to enable ageing in place. Community care and support to enable people with dementia to remain in their own home is recommended. While previous research shows a small positive effect of respite care for carers of people with dementia, there is no current evidence showing the benefits or adverse effects of respite care for care recipients.

Compact multicolor two-photon fluorescence microscopy enabled by tailorable continuum generation from self-phase modulation and dispersive wave generation

Published: October 2022

By precisely managing fiber-optic nonlinearity with anomalous dispersion, we have demonstrated the control of generating plural few-optical-cycle pulses based on a 24-MHz Chromium:forsterite laser, allowing multicolor two-photon tissue imaging by wavelength mixing. The formation of high-order soliton and its efficient coupling to dispersive wave generation leads to phase-matched spectral broadening, and we have obtained a broadband continuum ranging from 830 nm to 1200 nm, delivering 5-nJ pulses with a pulse width of 10.5 fs using a piece of large-mode-area fiber. We locate the spectral enhancement at around 920 nm for the two-photon excitation of green fluorophores, and we can easily compress the resulting pulse close to its limited duration without the need for active pulse shaping. To optimize the wavelength mixing for sum-frequency excitation, we have realized the management of the power ratio and group delay between the soliton and dispersive wave by varying the initial pulse energy without additional delay control. We have thus demonstrated simultaneous three-color two-photon tissue imaging with contrast management between different signals. Our source optimization leads to efficient two-photon excitation reaching a 500-µm imaging depth under a low 14-mW illumination power. We believe our source development leads to an efficient and compact approach for driving multicolor two-photon fluorescence microscopy and other ultrafast investigations, such as strong-field-driven applications.
Generation of the Airy beam based on the truncated asymptotic expression of the Airy function using a transmissive metasurface
Authors: Xue Hao , Zhang Song , Zhao Shihao , Xia Dexiao , Li Long
Published: October 2022

This paper proposes a phase-only modulation method to improve the main lobe's efficiency of the Airy beam based on the truncated asymptotic expression of the Airy function. As the truncated asymptotic expression can greatly reduce the range of amplitude modulation, it can be applied to the equal-amplitude modulation method with less amplitude error, which simplifies the design difficulty of the device and improves the beam's efficiency. A transmissive metasurface with a relative bandwidth of 10% is further adapted to generate the Airy beam with characteristics of non-diffraction, self-bending, and high-efficiency, which benefits the practical application of the Airy beam.
Thin-film lithium-niobate modulator with a combined passive bias and thermo-optic bias
Authors: Wang Mengke , Li Junhui , Yao Hao , Li Xuepeng , Wu Jieyun , Chiang Kin Seng , Chen Kaixin
Published: October 2022

It is essential to bias a thin-film lithium-niobate Mach-Zehnder electro-optic (EO) modulator at the desired operation condition to ensure optimal performance of the modulator. While thermo-optic (TO) control can solve the problem of bias drift, it consumes significant electric power. In this paper, we propose a technique to largely reduce bias power consumption by combining passive bias and TO bias. In our design, waveguide sections with different widths are introduced in the two arms of the MZ modulator to produce a desired phase difference of π/2 rad (the desired operation condition), and local heating with electrode heaters placed on the waveguides is employed to provide compensation for any phase drift caused by fabrication errors and other effects. As the TO control only serves to compensate for small errors, the electric power required is low and the response is fast. To demonstrate our technique experimentally, we fabricate several modulators of the same design on the same chip. Our experimental modulators can operate up to ∼40 GHz with a half-wave voltage of ∼2.0 V over a wide optical bandwidth, and the performances are insensitive to ambient temperature variations. The TO bias powers required range from 1 mW to 15 mW, and the thermal rise and fall times are 47 µs and 14 µs, respectively. Our technique can facilitate the development of practical high-speed EO modulators on the lithium-niobate-on-insulator platform.

Published: October 2022

In this Letter, we propose an optical delay-weight spiking neural network (SNN) architecture constructed by cascaded frequency and intensity-switched vertical-cavity surface emitting lasers (VCSELs). The synaptic delay plasticity of frequency-switched VCSELs is deeply studied by numerical analysis and simulations. The principal factors related to the delay manipulation are investigated with the tunable spiking delay up to 60 ns. Moreover, a two-layer spiking neural network based on the delay-weight supervised learning algorithm is applied to a spiking sequence pattern training task and then a classification task of the Iris dataset. The proposed optical SNN provides a compact and cost-efficient solution for delay weighted computing architecture without considerations of extra programmable optical delay lines.

A novel, to the best of our knowledge, broad-area distributed feedback laser with high-order surface curved gratings has been fabricated based on standard near ultraviolet lithography. The characteristics of increasing output power and mode selection are achieved simultaneously by using a broad-area ridge as well as an unstable cavity structure composed of curved gratings and a high-reflectivity coated rear facet. Suppression of high-order lateral modes is realized by setting current injection/non-injection regions and asymmetric waveguides. This DFB laser emitting around 1070 nm has achieved a spectral width of 0.138 nm and a maximum output power of 915 mW kink-free optical power. The threshold current and side-mode suppression ratio of the device are 370 mA and 33 dB, respectively. The simple manufacturing process and stable performance give this high-power laser broad application prospects in the fields of light detection and ranging, laser pumps, optical disk access, etc.

matrices called a pair-potential matrix (PPM) and a pair-structure matrix (PSM) are introduced to jointly characterize the scattered field. We show that the cross-spectral density function of the scattered field equals the trace of the product of the PSM and the transpose of the PPM, and thus these two matrices allow us to determine all the second-order statistical properties of the scattered field. Based on this, the spectral degree of coherence (SDOC) of the scattered field is further analyzed. In a special case where the spatial distributions of the scattering potentials of particles of different types are similar and the same is true of their density distributions, it is found that the PPM and the PSM will reduce to two new matrices whose elements separately quantify the degree of angular correlation of the scattering potentials of particles and their density distributions, and the number of species of particles in this special case will appear as a scaled factor to ensure the normalization of the SDOC. The importance of our new approach is illustrated by an example.

Published: October 2022

We demonstrate a compact hybrid lithium niobate microring laser by butt coupling a commercial 980-nm pump laser diode chip with a high-quality Er3+-doped lithium niobate microring chip. Single-mode lasing emission at 1531-nm wavelength from the Er3+-doped lithium niobate microring can be observed with the integrated 980-nm laser pumping. The compact hybrid lithium niobate microring laser occupies the chip size of 3 mm × 4 mm × 0.5 mm. The threshold pumping laser power is 6 mW and the threshold current is 0.5 A (operating voltage 1.64 V) at atmospheric temperature. The spectrum featuring single-mode lasing with small linewidth of 0.05 nm is observed. This work explores a robust hybrid lithium niobate microring laser source which has potential applications in coherent optical communication and precision metrology.

Published: October 2022

In this paper, we have presented a novel plasmonic Refractive Index (RI) sensing scheme based on a rewritable optical disc structure with customized dimer-like nanopatterns. We have performed the finite-difference time-domain (FDTD) simulation for this work to exhibit the optical resonant response and sensing performance of our proposed sensing platform. We have also investigated how the changes in the different structural parameters affect the resonant wavelength. The high refractive index sensitivity of 768nm/RIU allowed our sensing system to achieve a resolution limit for blood Hemoglobin(Hb) detection superior to most Hb sensors previously reported. The use of the built-in grating structure of the optical disc, the ability to create customized patterns, and the high resolution achieved in blood Hb detection suggest the potential of our proposed RI sensor as a cost-efficient, reliable sensing technology for medical applications.
A caspase–RhoGEF axis contributes to the cell size threshold for apoptotic death in developing Caenorhabditis elegans

Published: October 2022

A cell’s size affects the likelihood that it will die. But how is cell size controlled in this context and how does cell size impact commitment to the cell death fate? We present evidence that the caspase CED-3 interacts with the RhoGEF ECT-2 in Caenorhabditis elegans neuroblasts that generate “unwanted” cells. We propose that this interaction promotes polar actomyosin contractility, which leads to unequal neuroblast division and the generation of a daughter cell that is below the critical “lethal” size threshold. Furthermore, we find that hyperactivation of ECT-2 RhoGEF reduces the sizes of unwanted cells. Importantly, this suppresses the “cell death abnormal” phenotype caused by the partial loss of ced-3 caspase and therefore increases the likelihood that unwanted cells die. A putative null mutation of ced-3 caspase, however, is not suppressed, which indicates that cell size affects CED-3 caspase activation and/or activity. Therefore, we have uncovered novel sequential and reciprocal interactions between the apoptosis pathway and cell size that impact a cell’s commitment to the cell death fate.

Background

There are limited data on the performance characteristics of ultrasound for the diagnosis of pulmonary tuberculosis in both HIV-positive and HIV-negative persons. The objective of this proof-of-concept study was to determine the sensitivity and specificity of ultrasound for the diagnosis of tuberculosis in adults.

Methods

Comprehensive thoracic and focused abdominal ultrasound examinations were performed by trained radiologists and pulmonologists on adults recruited from a community multimorbidity survey and a primary healthcare clinic in KwaZulu-Natal Province, South Africa. Sputum samples were systematically collected from all participants. Sensitivity and specificity of ultrasound to detect tuberculosis were calculated compared to a reference standard of i) bacteriologically-confirmed tuberculosis, and ii) either bacteriologically-confirmed or radiologic tuberculosis.

Results

Among 92 patients (53 [58%] male, mean age 41.9 [standard deviation 13.7] years, 49 [53%] HIV positive), 34 (37%) had bacteriologically-confirmed tuberculosis, 8 (9%) had radiologic tuberculosis with negative bacteriologic studies, and 50 (54%) had no evidence of active tuberculosis. Ultrasound abnormalities on either thoracic or abdominal exams were detected in 31 (91%) participants with bacteriologic tuberculosis and 27 (54%) of those without tuberculosis. Sensitivity and specificity of any ultrasound abnormality for bacteriologically-confirmed tuberculosis were 91% (95% confidence interval [CI] 76%–98%) and 46% (95% CI 32%–61%). Sensitivity and specificity of any ultrasound abnormality for either bacteriologically-confirmed or radiologic tuberculosis were 86% (95% CI 71%–95%) and 46% (95% CI 32%–61%). Overall performance did not appear to differ markedly between participants with and without HIV.

Conclusion

A comprehensive ultrasound scanning protocol in adults in a high TB burden setting had high sensitivity but low specificity to identify bacteriologically-confirmed tuberculosis.

Introduction

Clinical Depression and the subsequent low immunity is a comorbidity that can act as a risk factor for the severity of COVID-19 cases. Antidepressants such as Selective serotonin reuptake inhibitor and Serotonin-norepinephrine reuptake inhibitors are associated with immune-modulatory effects, which dismiss inflammatory responses and reduce lung tissue damage. The current systematic review and meta-analysis aims to evaluate the effect of antidepressant drugs on the prognosis and severity of COVID-19 in hospitalized patients.

Methods

A systematic search was carried out in PubMed/Medline, EMBASE, and Scopus up to June 14, 2022. The following keywords were used: "COVID-19", "SARS-CoV-2", "2019-nCoV", "SSRI", "SNRI", “TCA”, “MAOI”, and “Antidepressant”. A fixed or random-effect model assessed the pooled risk ratio (RR) with 95% CI. We considered P < 0.05 as statistically significant for publication bias. Data were analyzed by Comprehensive Meta-Analysis software, Version 2.0 (Biostat, Englewood, NJ).

Results

Fourteen studies were included in our systematic review. Five of them were experimental with 2350, and nine of them were observational with 290,950 participants. Eight out of fourteen articles revealed the effect of antidepressants on reducing the severity of COVID-19. Selective serotonin reuptake inhibitors drugs, including Fluvoxamine, Escitalopram, Fluoxetine, and Paroxetine, and among the Serotonin-norepinephrine inhibitors medications Venlafaxine, are reasonably associated with reduced risk of intubation or death. Five studies showed no significant effect, and only one high risk of bias article showed the negative effect of antidepressants on the prognosis of Covid-19. The meta-analysis of clinical trials showed that fluvoxamine could significantly decrease the severity outcomes of COVID-19 (RR: 0.763; 95% CI: 0.602–0.966, I2: 0.0)

Findings

Most evidence supports that the use of antidepressant medications, mainly Fluvoxamine, may decrease the severity and improve the outcome in hospitalized patients with SARS-CoV-2. Some studies showed contradictory findings regarding the effects of antidepressants on the severity of COVID-19. Further clinical trials should be conducted to clarify the effects of antidepressants on the severity of COVID-19.

The objective of this study was to describe real-world health-related quality of life (HRQoL) and treatment satisfaction of ibrutinib-treated patients with CLL compared to a reference group. This study was completed in two parts. The first portion (Norming Study) was a US online survey conducted to serve as a reference population. The Norming Study included a total of 139 patients with CLL, excluding those treated with ibrutinib: 64 were treatment naive (Tx naive), 36 were 1st line (1L), and 38 were in or had completed ≥2 lines (2L+) patients with CLL. The second portion (CLL Ibrutinib Study) included 1L and 2L+ ibrutinib patients with CLL treated for ≥6 months in which 118 patients (1L n = 88 and 2L+ n = 30) completed the study. Respondents completed demographic and clinical information and the following HRQoL surveys: (Short Form-12v2® Health Survey [SF-12v2], Functional Assessment of Cancer Therapy-General [FACT-G], FACT-Leukemia [FACT-Leu] Functional Assessment of Chronic Illness Therapy [FACIT]-Fatigue, and Cancer Therapy Satisfaction Questionnaire [CTSQ]). Higher scores indicate better HRQoL/treatment satisfaction. Differences in effect sizes between the two samples at the group level were calculated using Hedges’ g. Medium to large positive effects were seen in the CLL Ibrutinib group on several measures compared to the Reference Study groups. The FACT-G total score was 89.2±11.1 for CLL Ibrutinib Study patients compared to 75.8±22.6 CLL Norming Tx naïve patients, 61.3±21.8 in 1L, and 61.7±20.7 in 2L+. Similar trends were seen with FACT-Leu total score and FACIT-Fatigue. CLL Ibrutinib Study patients scored higher on all CTSQ domain scores compared to the CLL Norming patients treated with other CLL therapies. We found that Ibrutinib-treatment had better HRQoL and treatment satisfaction compared to patients receiving other therapies, irrespective of line of therapy.

As of today, surprisingly little is known about the subjective well-being of faculty in general, but especially when teaching online and during a time of pandemic during lockdowns in particular. To narrow this research gap, the present study systematically compared the subjective well-being of faculty teaching face-to-face before to those teaching online during the COVID-19 pandemic, adopting a self-determination theory framework. The data reported here stem from a study conducted before the pandemic (Sample 1, n = 101) and which repeated-measures survey design we replicated to collect corresponding data during the pandemic (Sample 2, n = 71). Results showed that faculty teaching online during the pandemic reported impaired satisfaction of all three basic needs, that is reduced autonomy, competence, and especially relatedness, as well as impaired subjective well-being (clearly reduced enjoyment and reduced teaching satisfaction; increased anger and a tendency towards more shame) compared to faculty teaching face-to-face before the pandemic. Yet pride, anxiety, and boredom were experienced to a similar extent across both samples. The effects of the teaching format on the different aspects of subjective well-being were overall mediated in self-determination-theory-congruent ways by the satisfaction of the basic needs for autonomy, competence, and relatedness. We conclude for a post-pandemic future that online teaching will supplement rather than replace face-to-face teaching in higher education institutions, as their importance for building relationships and satisfying social interactions not only for students but also for faculty seem to have been underestimated so far.
