The World’s Literatures
Authors: Newman Jane O. , Sadan Ron
Published: December 2022

Erich Auerbach (1892–1957), best known as the author of Mimesis: Dargestellte Wirklichkeit in der abendländischen Literatur (1946; Mimesis: The Representation of Reality in Western Literature, 1953), wrote about the eighteenth-century philologist and philosopher of history Giambattista Vico (1668–1744) fifteen times over the course of his life. The translations offered here are among the earliest of these writings. These early essays on Vico refine the picture both of Auerbach himself and of the significance of his work for comparative literary studies today in important ways. First, they allow a reconsideration of the progressivist literary historical secularization thesis often claimed for Auerbach’s oeuvre writ large. Second, they display Auerbach’s early aspiration to reach “ein allgemeineres Publikum” (a more general public) through his work as a “Schriftsteller” (writer). Finally, they open a window onto the Vichian calculus upon which his assessment of the texts discussed in Mimesis may have been based. The modes of representation (Darstellung) Auerbach favored may thus be understood not as part of a restrictive canon but rather as examples of the human “Schauspiel” (drama) and fateful “Lage . . . der Menschen” (human condition) in a world whose literatures reach far beyond the European archive enshrined in Mimesis.
Paul de Man’s Flemish
Authors: Vanwesenbeeck Birger
Published: December 2022

This essay seeks to fill a gap in the scholarship on Paul de Man by taking stock of the scattered references to Flemish in his later writings. Taking its cue from a passing remark in the most recent de Man biography—namely, that late in life the theorist attested repeatedly in private to the experience of “losing” his native tongue—this article has two aims. One is to show that de Man’s later works bear witness to this ongoing experience of native-linguistic loss; the other is to relate this experience to the theory of deconstruction that de Man had espoused by then. To this latter end, the essay establishes a comparison between de Man’s later works, from Allegories of Reading (1979) onward, and Jacques Derrida’s 1996 autobiographical essay Monolingualism of the Other in order to show how the deconstructive theory conception of language-as-other is rooted in these two thinkers’ respective experiences of native-linguistic loss. The essay closes by reflecting on the contrast between a major language's relative resilience to native-linguistic loss, as in the case of Derrida’s French, and the far more precarious condition of a minor language in exile such as de Man's Flemish.
The mitotic role of Adenomatous Polyposis Coli requires its bilateral interaction with tubulin and microtubules

Published: December 2022

Adenomatous Polyposis Coli (APC) is a scaffold protein with tumour suppressor properties. Mutations causing the loss of its C-terminal domain (APC-C) - bearing cytoskeleton-regulating sequences - correlate with colorectal cancer. The cellular roles of APC in mitosis are widely studied, but the molecular mechanisms of its interaction with the cytoskeleton are poorly understood. Here, we investigated how APC-C regulates microtubule properties, and found it to promote both microtubule growth and shrinkage. Strikingly, APC-C accumulates at shrinking microtubule extremities, a common characteristic of depolymerases. Cryo-electron microscopy revealed that APC-C adopts an extended conformation along the protofilament crest and shows the presence of ring-like tubulin oligomers around microtubules which required the presence of two APC-C sub-domains. A mutant of APC-C incompetent to decorate microtubules with ring-like tubulin oligomers exhibited a reduced effect on microtubule dynamics. Finally, whereas native APC-C rescued defective chromosome alignment in metaphase cells silenced for APC, the ring-incompetent mutant failed to correct mitotic defects. Thus, the bilateral interaction of APC-C with tubulin and microtubules likely contributes to its mitotic functions.

Η ελάχιστα επεμβατική χειρουργική υποβοηθούμενη από ρομποτικά συστήματα κερδίζει σε δημοτικότητα την παραδοσιακή ελάχιστα επεμβατική χειρουργική. Παρά το γεγονός αυτό υπάρχουν περιορισμοί στις δυνατότητες που προσφέρει η τρέχουσα τεχνολογία σε θέματα μεθόδων ελέγχου και ανάδρασης δύναμης στον χειρούργο. Σε μια τέτοιου είδους εργασία χρησιμοποιούνται μακριά και λεπτά εργαλεία που εισάγονται μέσα στο σώμα του ασθενούς μέσω μικροσκοπικών τομών στο δέρμα του. Έτσι το ένα άκρο του εργαλείου βρίσκεται μέσα στα ζωτικά όργανα του ασθενούς στα οποία χρειάζεται να γίνει η χειρουργική επέμβαση τα οποία συνήθως περιβάλλονται από ευαίσθητες δομές όπως αρτηρίες. Το άλλο άκρο του εργαλείου το οποίο είναι προσαρτημένο στο ρομπότ χειρίζεται από τον χειρουργό είτε άμεσα ασκώντας δυνάμεις στον καρπό του ρομπότ που φέρει το χειρουργικό εργαλείο είτε έμμεσα χρησιμοποιώντας μια απτική συσκευή σε ένα τηλερομποτικό σύστημα. Σε αυτήν την διδακτορική διατριβή σχεδιάστηκαν και αναπτύχθηκαν μέθοδοι ελέγχου ρομποτικού βραχίονα γενικού σκοπού με στόχο την ελαχιστοποίηση του τραυματισμού του ασθενούς με την αποφυγή των ευαίσθητων δομών μέσω ανάδρασης δύναμης και της πλευρικής κίνησης της θύρας εισόδου του εργαλείου καθώς και την επίτευξη ομαλής επίδοσης. Οι προτεινόμενοι μέθοδοι εξετάστηκαν θεωρητικά και επικυρώθηκαν μέσω προσομοιώσεων και πειραμάτων.

Χαρτογράφιση της λεμφικής διασποράς στον καρκίνο τραχήλου της μήτρας και η σημασία του λεμφαδένα φρουρού
Authors: Κουτρούμπα Ιωάννα
Published: December 2022

Εισαγωγή: Λόγω των επακόλουθων επιπλοκών της πυελικής λεμφαδενεκτομής σε ασθενείς με πρώιμο στάδιο καρκίνου του τραχήλου της μήτρας, η τεχνική του Φρουρού Λεμφαδένα (SLN) χρησιμοποιείται όλο και περισσότερο. Αυτή η μελέτη είχε στόχο να διερευνήσει την ανιχνευσιμότητα του Λεμφαδένα Φρουρού χρησιμοποιώντας μπλε του μεθυλενίου και να διερευνήσει τη διαγνωστική ακρίβεια της βιοψίας του. Μεθοδολογία: Μια μελέτη διεξήχθη από τον Σεπτέμβριο του 2015 έως τον Αύγουστο του 2018 και συμπεριέλαβε 90 γυναίκες με καρκίνο του τραχήλου της μήτρας, σταδίου IA1-IIA1 FIGO (Διεθνής Ομοσπονδία Γυναικολογίας και Μαιευτικής-2009). Το μπλε του μεθυλενίου εγχύθηκε ενδοτραχηλικά. Τυχόν ανιχνευθέντες βαμμένοι λεμφαδένες στάλθηκαν για ταχεία βιοψία κατεψυγμένου τμήματος (FSB), ακολουθούμενη από αμφοτερόπλευρη πυελική λεμφαδενεκτομή. Η προγνωστική ικανότητα του Λεμφαδένα Φρουρού αξιολογήθηκε με στατιστικούς όρους μετά από σύγκριση της διεγχειρητικής βιοψίας και του τελικού ιστοπαθολογικού πορίσματος. Αποτελέσματα: Η ευαισθησία, η ειδικότητα, το ψευδώς αρνητικό ποσοστό, η θετική προγνωστική αξία και η αρνητική προγνωστική αξία (NPV) ήταν 55,6%, 95,1%, 4,9%, 55,6% και 95,1% αντίστοιχα. Η απόδοση του Λεμφαδένα Φρουρού σε ασθενείς με μέγεθος όγκου ≤2,2 cm, αρνητική συμμετοχή του λεμφαγγειακού χώρου και βάθος στρωματικής διήθησης ≤5 mm ήταν ανώτερη (ευαισθησία 100%, ειδικότητα 93,5%, NPV 100%). Συμπεράσματα: Η τεχνική του Φρουρού Λεμφαδένα με την αποκλειστική χρήση μπλε χρωστικής βαφής είναι μια εφικτή και επαρκής εναλλακτική λύση έναντι της συστηματικής λεμφαδενεκτομής σε πρώιμο στάδιο καρκίνου του τραχήλου της μήτρας σε επιλεγμένους ασθενείς, δεδομένου ότι εφαρμόζεται ένας αυστηρός αλγόριθμος.
State estimation in logical and stochastic discrete event systems
Authors: Κέρογλου Χριστόφορος
Published: December 2022

Η παρούσα διδακτορική διατριβή μελετά τη διαδικασία της εκτίμησης κατάστασης (state estimation) σε πολύπλοκα διασυνδεδεμένα συστήματα, τα οποία μοντελοποιούνται σαν συστήματα διακριτών γεγονότων (discrete event systems) ή στοχαστικά συστήματα διακριτών γεγονότων (stochastic discrete event systems). Ένα από τα σημαντικά κίνητρα για να ασχοληθούμε με τα προβλήματα που σχετίζονται με την εκτίμηση κατάστασης, είναι ο σημαντικός ρόλος που διαδραματίζουν σε θεωρητικά προβλήματα, όπως την κατηγοριοποίηση (classification) και την ανίχνευση σφαλμάτων (fault diagnosis). Ιδιαίτερα, η παρούσα διατριβή έχει σκοπό της να εξερευνήσει τις έννοιες της ακριβούς εκτίμησης κατάστασης (detectability), της ανίχνευσης σφαλμάτων, και της κατηγοριοποίησης, χρησιμοποιώντας τεχνικές εκτίμησης κατάστασης, κατάλληλες για συστήματα διακριτών γεγονότων και στοχαστικά συστήματα διακριτών γεγονότων. Ερευνούμε αυτά τα προβλήματα σε μη ντετερμινιστικά και στοχαστικά πεπερασμένα αυτόματα, σε τρεις διαφορετικές περιπτώσεις (συγκεκριμένα, μονολιθικά, αποκεντρωμένα και κατανεμημένα συστήματα). Ειδικότερα, ερευνούμε την έννοια της ανίχνευσης σφαλμάτων σε κατανεμημένα συστήματα, για μη- ντετερμινιστικά πεπερασμένα αυτόματα, σε συνθήκες περιορισμένης επικοινωνίας. Επίσης, εισάγουμε και επαληθεύουμε στοχαστικές έννοιες για τα προβλήματα της ακριβούς εκτίμησης κατάστασης και ανίχνευσης σφαλμάτων αναλύοντας την ασυμπτωτική συμπεριφορά των συστημάτων. Τέλος, προτείνουμε και συζητούμε διάφορες μεθόδους στο πρόβλημα της κατηγοριοποίησης σε κρυφά μαρκοβιανά μοντέλα (hidden Markov models). Αναπτύσσουμε διάφορες μεθόδους υπολογισμού ανωτάτων ορίων για την πιθανότητα λάθους κατηγοριοποίησης, που ασυμπτωτικά τείνουν στο μηδέν, κάτω από καθορισμένες ικανές συνθήκες.

Ο Ελλαδικός χώρος ανήκει στις πιο τεκτονικά και σεισμικά ενεργές περιοχές παγκοσμίως, με αποτέλεσμα να συναντάται μια πληθώρα ενεργών τεκτονικών δομών από τις οποίες κάποιες έχουν μελετηθεί ενδελεχώς, κάποιες λιγότερο, ενώ κάποιες άλλες παραμένουν ακόμα ανεξερεύνητες. Αυτό έχει ως αποτέλεσμα την ύπαρξη μιας μεγάλης ποικιλίας δεδομένων από διάφορες έρευνες, τόσο σε ποσότητα όσο και σε ποιότητα, τα οποία είναι είτε διάχυτα ή κρυμμένα μέσα στην πολυάριθμη βιβλιογραφία. Η ανομοιογένεια αυτή κάνει την ανεύρεση πληροφοριών, μια δύσκολη και χρονοβόρο διαδικασία, με αποτέλεσμα η δημιουργία μιας βάσης δεδομένων να φαίνεται αναγκαία. Η δημιουργία μιας τέτοιας γεωβάσης που επιχειρήθηκε στη παρούσα διατριβή δεν είναι χρήσιμη μόνο για επιστημονικούς σκοπούς, όπως π.χ. για τη δημιουργία γεωδυναμικών μοντέλων ή την ερμηνεία της σεισμοτεκτονικής συμπεριφοράς διαφόρων περιοχών. Η εκτίμηση της σεισμικής επικινδυνότητας, η οποία και έχει άμεσο κοινωνικοοικονομικό αντίκτυπο, είναι μία ακόμη σημαντική έρευνα για την οποία μια βάση δεδομένων μπορεί να αποτελέσει αναπόσπαστο εργαλείο.Δύο παράμετροι των ενεργά τεκτονικών δομών που συντριπτικά απουσιάζουν από τη διαθέσιμη βιβλιογραφία και επιχειρήθηκε να προσδιοριστούν στη παρούσα διατριβή είναι το μέγιστο βάθος στο οποίο τα ενεργά ρήγματα φτάνουν και ο ρυθμός ολίσθησης. Για το πρώτο πραγματοποιήθηκαν ρεολογικά προφίλ για τον προσδιορισμό της θραυσιγενούς-πλαστικής ζώνης μετάβασης και για το δεύτερο συνδυάστηκαν θεμελιώδεις μαθηματικές εξισώσεις της παραμόρφωσης με εισαγόμενα δεδομένα από τους κύριους άξονες παραμόρφωσης του Ελλαδικού χώρου που προκύπτουν από μετρήσεις GPS.Η Ελληνική Βάση Δεδομένων Σεισμογενών Πηγών αποτελεί ένα πολύ-εργαλείο το οποίο μεταξύ άλλων μπορεί να χρησιμοποιηθεί, όπως επιχειρήθηκε στη παρούσα διατριβή, σε διάφορα γεωδυναμικά-σεισμοτεκτονικά μοντέλα, στον προσδιορισμό μεταβολής στατικών τάσεων και εδαφικών μετατοπίσεων μετά από ολίσθηση-σεισμική δράση, και για τη συμβολή στη σεισμική επικινδυνότητα.

Published: December 2022

Mendelian randomization (MR) is increasingly used for generating estimates of the causal impact of exposures on outcomes. Evidence suggests a causal role of excess adipose tissue (adiposity) on many health outcomes. However, this body of work has not been systematically appraised.

We systematically reviewed and meta-analysed results from MR studies investigating the association between adiposity and health outcomes prior to the SARS-CoV-2/COVID-19 pandemic (PROSPERO: CRD42018096684). We searched Medline, EMBASE, and bioRxiv up to February 2019 and obtained data on 2,214 MR analyses from 173 included articles. 29 meta-analyses were conducted using data from 34 articles (including 66 MR analyses) and results not able to be meta-analysed were narratively synthesised.

Body mass index (BMI) was the predominant exposure used and was primarily associated with an increase in investigated outcomes; the largest effect in the meta-analyses was observed for the association between BMI and polycystic ovary syndrome (estimates reflect odds ratios (OR) per standard deviation change in each adiposity measure): OR = 2.55; 95% confidence interval (CI) = 1.22–5.33. Only colorectal cancer was investigated with two exposures in the meta-analysis: BMI (OR = 1.18; 95% CI = 1.01–1.37) and waist-hip ratio (WHR; OR = 1.48; 95% CI = 1.08–2.03). Broadly, results were consistent across the meta-analyses and narrative synthesis.

Consistent with many observational studies, this work highlights the impact of adiposity across a broad spectrum of health outcomes, enabling targeted follow-up analyses. However, missing and incomplete data mean results should be interpreted with caution.

Aquestexercici permetrà demostrar que la legitimació de la naixent Segona RepúblicaEspanyola es va basar en l’aplicació d’un projecte específic de moralitzacióde la política. Igualment, es podrà observar com l’escàndol vaadaptar-se a les lluites polítiques d’ambdues bandes dels Pirineus, amb elementstransnacionals compartits.

El Trastorno de Déficit de Atención e Hiperactividad -(T)DAH- desde una mirada anticapacitista
Authors: Nieto Llarena Iraia
Published: December 2022

Muchos colectivos minorizados tienen barreras para el acceso a diferentes espacios de la vida como los estudios, el trabajo, el ocio o las relaciones sociales. Cuando se reclama interseccionalidad, raramente se incluyen las condiciones de discapacidad y dentro de éstas, las neurodivergencias. El capacitismo hace referencia a la violencia social y normalizada, que sobrevaloriza determinados funcionamientos e infravalora otros, fomentando, hacia estos últimos, prejuicios, estigma, discriminación y exclusión. Este artículo narra cómo el capacitismo influye a las personas con Trastorno de Déficit de Atención e Hiperactividad –(T)DAH-. En la actualidad, hay mucha desinformación sobre el (T)DAH, reproduciéndose diferentes mitos en la comunidad sanitaria y otros espacios sociales. En este artículo se resaltan tanto los mitos como la importancia de conocer y aplicar el modelo de la neurodiversidad, actualizarse como profesionales y personas sobre el (T)DAH y cuestionar las barreras y privilegios presentes en nuestro contexto sociocultural. A lo largo del mismo, se puede reflexionar sobre actitudes y metodologías de la vida diaria, que fomentan dinámicas de exclusión hacia personas (T)DAH.

Memorias e identidad cruzando fronteras.
Authors: Sanmartí Astor Maria
Published: December 2022

En mi investigación “memoria e identidad cruzando fronteras. 7 relatos de mujeres migrantes”, realizada dentro del máster en estudios Amerindios de la facultad de Antropología de la Universidad Nacional de Educación a Distancia, se ha preguntado a distintas mujeres de raíces indígenas del Abya Yala que viven actualmente en la provincia de Barcelona, si para ellas ha sido posible mantener su identidad y orígenes a pesar de los contextos radicalmente distintos donde las ha llevado la migración. A través de una metodología en la que destacan las historias de vida, como vía para saber más de la realidad podemos acercarnos a relatos sobre la diáspora y a los recuerdos previos a ella. Con una metodología en la que destacan las historias de vida, podemos acercarnos a algunos elementos que las mujeres expresan que las conectan a su cultura e identidad, principalmente el Arte, el ritual y el activismo. El Arte es, para la mayoría de ellas, una forma de expresión que las conecta con sus orígenes a través de lo estético y lo lúdico, sin embargo, no lo viven nada más como un entretenimiento sino también como una reivindicación de sus saberes ancestrales. El ritual, por otro lado, es vivido de forma particular por cada mujer, pero todas coinciden en que forma parte de su día a día. Finalmente, el activismo está presente en la mayoría de sus historias, a pesar de que unas se implican más en movimientos de reivindicación o denuncia social. Este permite no solamente defender el territorio sino defender también sus derechos como mujeres migradas
«Soy esposa de dios». Una etnografia sobre la construcció de la identitat femenina en els convents de vida contemplativa
Authors: Calls Cobos Joana
Published: December 2022

Les adoratrius perpètues formen part d’una comunitat de dones cristianes de vida contemplativa. Es tracta de dones cristianes que van decidir en un moment de la seva vida adulta convertir-se en monges de clausura. Les adoratrius, en el moment en el qual entren a formar part dins de la comunitat, renuncien a la seva llibertat individual i lliure circulació per la ciutat i l’espai públic com a sacrifici personal per poder adorar a la divinitat constantment, a diferència d’altres religioses. A partir d’una perspectiva etnogràfica, aquest treball de final de grau analitza la construcció de la dona religiosa a partir del treball de camp realitzat a un Convent de Vida Contemplativa en una ciutat que forma part de l’Àrea Metropolitana de Barcelona. Per tal d’aproximar-me a aquesta realitat, he participat en activitats que realitzen de forma comunitària i periòdica, tals com les misses i altres rituals. El treball diari en el qual estan sotmeses es basa en el treball de cures que practiquen quotidianament, dins i fora dels límits del convent. Gràcies a aquesta immersió portada a terme durant dos anys he arribat a la conclusió que les activitats al voltant de les cures són les que encara avui marquen la construcció de la identitat de les adoratrius. La constància, la dedicació i la passió que senten per la divinitat i per l’església acaba esdevenint la raó de la seva existència i on les cures, on esdevenen una part fonamental dins de la seva existència, com a dona i com a religioses.

«Ulls per on la policia no hi veu» (o, imaginando al «enemigo»)
Authors: Espinach Casacuberta Marina
Published: December 2022

En este artículo me aproximo al activismo cívico-securitario en Ciutat Vella en Barcelona a través de una plataforma online de vigilancia y denuncia ciudadana. Con ello, investigo las continuidades y discontinuidades entre el vigilantismo en línea y las formas clásicas de vigilantismo (off-line), y como el primero se reproduce con efectividad a través de particularidades del espacio digital. Estas nuevas formas online, además, han posibilitado, en el contexto etnográfico investigado, vehicular formas preexistentes de: exclusión y distinción social; reafirmación de una supuesta superioridad moral y estrategias de preservación de un orden moral; y de control social y punición. Además, en el emplazamiento digital de las actividades, las dimensiones disciplinaria y punitiva del vigilantismo se ejecutan por medio de una expresión concreta de lo visual -o lo visible- y el uso de imágenes, y en un momento de establecimiento de un nuevo régimen de visibilidad. Los apartados uno y dos los dedico a contextualizar el caso de estudio; exponer algunas particularidades metodológicas de la etnografía en línea; y a problematizar la categoría vigilantismo (del inglés vigilantism o vigilante activity) y argumentar porqué enmarco mi estudio en ella. En el punto tres profundizo sobre el caso concreto presentando algunos datos recogidos. En el punto cuatro recurro a la obra de Foucault para marcar las dos dimensiones principales de mi análisis –lo enunciable y lo visible. En los puntos cinco y seis, desarrollo la parte central del análisis de datos etnográficos; y el punto siete está dedicado a concluir el artículo.

In addition, combining the focusing with a polarization multiplexing principle to distinguish the spin direction of circular polarization light and generate the high-purity vortex beams with energy offset, the proposed capabilities have potential applications in the fields of polarization detection, optical beam research, and communication.

Published: December 2022

Channel estimation is a key technology in MIMO-OFDM wireless communication systems. Increasingly extensive application scenarios and exponentially growing data volumes of MIMO-OFDM systems have imposed greater challenges on the speed, latency, and parallelism of channel estimation based on electronic processors. Here, we propose a photonic parallel channel estimation (PPCE) architecture which features radio-frequency direct processing. Proof-of-concept experiment is carried out to demonstrate the general feasibility of the proposed architecture at different frequency bands (100 MHz, 4 GHz, and 10 GHz). The mean square errors (MSEs) between the experimental channel estimation results and the theoretically simulated ones lie on the order of 10−3. The bit error rates (BERs) are below the pre-forward error correction (pre-FEC) threshold. Besides, we analyze the performance of PPCE under different signal-to-noise ratios (SNRs), baseband symbol forms, and weight tuning precisions. The proposed PPCE architecture has the potential to achieve high-speed, highly parallel channel estimation in large-scale MIMO-OFDM systems after the photonic-electronic chip integration.

Published: December 2022

For over a decade hollow-core fibers have been used in optical gas sensors in the role of gas cells. However, very few examples of actual real-life applications of those sensors have been demonstrated so far. In this paper, we present a highly-sensitive hollow-core fiber based methane sensor. Mid-infrared distributed feedback interband cascade laser operating near 3.27 µm is used to detect gas inside anti-resonant hollow-core fiber. R(3) line near 3057.71 cm-1 located in ν3 band of methane is targeted. Compact, lens-free optical setup with an all-silica negative curvature hollow-core fiber as the gas cell is demonstrated. Using wavelength modulation spectroscopy and 7.5-m-long fiber the detection limit as low as 1.54 ppbv (at 20 s) is obtained. The demonstrated system is applied for a week-long continuous monitoring of ambient methane and water vapor in atmospheric air at ground level. Diurnal cycles in methane concentrations are observed, what proves the sensor’s usability in environmental monitoring.
Reference-frame-independent quantum key distribution with advantage distillation
Authors: Zhu Jian-Rong , Zhang Chun-Mei , Wang Rong , Li Hong-Wei
Published: December 2022

Advantage distillation (AD) provides a means of separating highly correlated raw key bits from weakly correlated information in quantum key distribution (QKD). In this Letter, we apply the AD method to improve the performance of reference-frame-independent QKD (RFI-QKD). Simulation results show that, compared with RFI-QKD without AD, RFI-QKD with AD can tolerate higher system errors and obtain better performance on the secret key rate and transmission distance. Furthermore, we extend the AD method to RFI measurement-device-independent QKD (RFI-MDI-QKD) and demonstrate that the AD method can improve the performance of RFI-MDI-QKD more significantly.
Fabrication parameters of spin coating hollow SiO2 nanospheres for antireflection films
Authors: Chang Tze-Chun , Zeng Tsung-Wei
Published: December 2022

Fabrication parameters of antireflection films made of spin coating hollow SiO2 nanospheres were investigated. The film thickness, film morphology and optical properties of the antireflection films were observed dependent on speed of spin coating. With a proper coating speed to produce film of desirable thickness, the antireflection film shows transmittance of 98.7% at λ = 550 nm. We applied a two-step coating to serve as an alternative way for fabrication of hollow SiO2 nanospheres antireflection films. For the antireflection films made by the two-step coating, a relatively improved uniformity in surface morphology and decrease in diffuse reflectance were found. The results suggest using the two-step coating method can be beneficial for uniformity in film morphology and optical properties of the antireflection films.
Efficient coding theory of dynamic attentional modulation
Authors: Młynarski Wiktor , Tkačik Gašper
Published: December 2022

Activity of sensory neurons is driven not only by external stimuli but also by feedback signals from higher brain areas. Attention is one particularly important internal signal whose presumed role is to modulate sensory representations such that they only encode information currently relevant to the organism at minimal cost. This hypothesis has, however, not yet been expressed in a normative computational framework. Here, by building on normative principles of probabilistic inference and efficient coding, we developed a model of dynamic population coding in the visual cortex. By continuously adapting the sensory code to changing demands of the perceptual observer, an attention-like modulation emerges. This modulation can dramatically reduce the amount of neural activity without deteriorating the accuracy of task-specific inferences. Our results suggest that a range of seemingly disparate cortical phenomena such as intrinsic gain modulation, attention-related tuning modulation, and response variability could be manifestations of the same underlying principles, which combine efficient sensory coding with optimal probabilistic inference in dynamic environments.

The ability of terrestrial vertebrates to effectively move on land is integrally linked to the diversification of motor neurons into types that generate muscle force (alpha motor neurons) and types that modulate muscle proprioception, a task that in mammals is chiefly mediated by gamma motor neurons. The diversification of motor neurons into alpha and gamma types and their respective contributions to movement control have been firmly established in the past 7 decades, while recent studies identified gene expression signatures linked to both motor neuron types. However, the mechanisms that promote the specification of gamma motor neurons and/or their unique properties remained unaddressed. Here, we found that upon selective loss of the orphan nuclear receptors ERR2 and ERR3 (also known as ERRβ, ERRγ or NR3B2, NR3B3, respectively) in motor neurons in mice, morphologically distinguishable gamma motor neurons are generated but do not acquire characteristic functional properties necessary for regulating muscle proprioception, thus disrupting gait and precision movements. Complementary gain-of-function experiments in chick suggest that ERR2 and ERR3 could operate via transcriptional activation of neural activity modulators to promote a gamma motor neuron biophysical signature of low firing thresholds and high firing rates. Our work identifies a mechanism specifying gamma motor neuron functional properties essential for the regulation of proprioceptive movement control.
The global burden of Chikungunya fever among children: A systematic literature review and meta-analysis
Authors: Nyamwaya Doris K. , Thumbi Samuel M. , Bejon Philip , Warimwe George M. , Mokaya Jolynne
Published: December 2022

Chikungunya fever (CHIKF) is an arboviral illness that was first described in Tanzania (1952). In adults, the disease is characterised by debilitating arthralgia and arthritis that can persist for months, with severe illness including neurological complications observed in the elderly. However, the burden, distribution and clinical features of CHIKF in children are poorly described. We conducted a systematic literature review and meta-analysis to determine the epidemiology of CHIKF in children globally by describing its prevalence, geographical distribution, and clinical manifestations. We searched electronic databases for studies describing the epidemiology of CHIKF in children. We included peer-reviewed primary studies that reported laboratory confirmed CHIKF. We extracted information on study details, sampling approach, study participants, CHIKF positivity, clinical presentation and outcomes of CHIKF in children. The quality of included studies was assessed using Joanna Briggs Institute Critical Appraisal tool for case reports and National Institute of Health quality assessment tool for quantitative studies and case series. Random-effects meta-analysis was used to estimate the pooled prevalence of CHIKF among children by geographical location. We summarised clinical manifestations, laboratory findings, administered treatment and disease outcomes associated with CHIKF in children. We identified 2104 studies, of which 142 and 53 articles that met the inclusion criteria were included in the systematic literature review and meta-analysis, respectively. Most of the selected studies were from Asia (54/142 studies) and the fewest from Europe (5/142 studies). Included studies were commonly conducted during an epidemic season (41.5%) than non-epidemic season (5.1%). Thrombocytopenia was common among infected children and CHIKF severity was more prevalent in children <1 year. Children with undifferentiated fever before CHIKF was diagnosed were treated with antibiotics and/or drugs that managed specific symptoms or provided supportive care. CHIKF is a significant under-recognised and underreported health problem among children globally and development of drugs/vaccines should target young children.
Music recharges people: Synchronized music during aerobic exercise leads to better self-regulation performance
Authors: Li Chenyang , Jin Chengji , Zhang Ziyun , Shi Peng
Published: December 2022

Previous studies have demonstrated that music has a positive effect on individuals during exercise and sports. We speculate that one of the mechanisms for this positive effect may be that music reduces the consumption of self-regulation strength. The primary objective of this study was to use a self-regulation strength model to explain the impact of music on individuals during aerobic exercises. Specifically, we examined the effects of synchronous music on college students’ depletion of self-regulation during aerobic exercises. The participants underwent a pre-test in which they had to maintain 50% maximum voluntary contraction (MVC) isometric grip and do exercise planning tasks. For subsequent power bicycle riding (aerobic exercise), the participants were divided into a music group and a control group. The music group performed aerobic exercises with synchronous music, while the control group performed aerobic exercises without music. After aerobic exercise, the participants underwent a post-test for isometric grip and exercise planning tasks. The results showed that the music group planned to reduce their efforts less for an upcoming exercise period (p < 0.01, d = 0.81), and their wrist flexor muscle group generated less electromyographic activation during an isometric grip task that maintained 50% MVC (p < 0.05, d = 0.80) than the control group. However, the two groups showed no difference in the duration of 50% MVC. This shows that: (a) for the same duration, participants in the music group required a lower degree of muscle activation than the control group, suggesting that music reduced the consumption of self-regulation strength in aerobic exercise; and (b) music decreased participants’ planned exertion declined, also suggesting that music reduced the consumption of self-regulation strength in aerobic exercise.
