Authors: Shaikh Saifullah , Munawar Lalarukh , Shakoor Shazia , Siddiqui Rabia
Published: December 2021

Objective: To evaluate the depression on different stages (mild, moderate and severe) among undergraduate students of pre-clinical & clinical settings on the basis of gender. Study Design and Setting: The cross sectional study was carried out among undergraduate medical students of Bahria University medical and dental College (BUMDC) Karachi from September 2017 – December 2017. Methodology: The participants were 125 medical students of first year MBBS and 125 students of final year MBBS which were labeled as pre-clinical and clinical groups respectively. The survey instrument used was PHQ-9 scale. This scale divides depression into mild, moderate and severe categories with the help of scores. Percentage of students in different levels of depression was calculated in both the groups. Results: Mild depression was experienced more (39%) in pre-clinical medical students and (32%) in clinical students. On the other hand clinical medical students showed an upward trend for “severe depression” (19%) as compare to preclinical students (6%) as showed in Table 1. Gender based comparison was done between male and female students in pre-clinical and clinical groups separately. Strikingly, the results showed that females were more depressed than males in both cohorts. Conclusion: It was concluded that severe depression was equal in males and females in the preclinical group as compared to clinical group. Gender based comparison showed that severe depression was higher in females than males of clinical years whereas mild and moderate depression was also more frequents in females of clinical years.

Published: December 2021

Objective: To review the mode of delivery and perinatal outcome in breech presentation in a tertiary care hospital. Study Design and Setting: Retrospective Analytical Study. Department of Obstetrics and Gynecology Unit-4, Bolan Medical Complex Hospital, Quetta, from 1st January 2012 to 31st December, 2016. Methodology: This retrospective analytical study included review of clinical records of all patients who delivered either vaginally or via caesarean section with breech presentation. Results: During the study period, 806 patients presented with breech (2.4%). Vaginal breech delivery was carried out in 71.8% patients and caesarean section was done in 28.2% patients. In vaginal breech group 30.7% patients were primigravida and 69.3% patients were multigravida. In caesarean section group 50.3% patients were primigravida and 49.7% were multigravida. Most common birth weight was between 2.5-3.5 kg in both group. Most common indication for cesarean section was breech with previous one LSCS. Conclusion: Like all vaginal births, vaginal breech delivery is not only beneficial in the chance of having a vaginal birth in future but also prevents from the complications of caesarean delivery.

Published: December 2021

Objective: The aim of the study was to investigate obstetricians’ perspective regarding dental management of pregnant patients. Study Design and Setting: It was questionnaire based study and was directed towards practicing obstetricians of Karachi. Methodology: A seven item questionnaire was formulated by focusing on different aspects of the oral healthcare of pregnant patients including need for regular dental visits, dental radiograph safety, awareness about the adverse pregnancy outcomes due to untreated dental infections, safe use of local anesthesia, antimicrobials and analgesics and the safe trimester for dental extractions. A total of 74 responses received were entered and descriptive analysis was done by SPSS version 16. Results: Out of 74 respondents, n = 47 (63.5%) were aware that untreated dental infection may lead to adverse pregnancy outcome, n = 20 (27%) actually advise regular dental check-ups to their patients; n = 29 (39.2%) respondents were in favor of leaving the decision for dental x-rays to the dentist and n = 14 (18.9%) respondents allowed dental x-rays anytime during pregnancy to their patients. Out of n = 74, n = 21 (28.4%) respondents permitted dental extractions under local anesthesia with adrenaline by taking some precautions. Co-Amoxiclav (Amoxicillin and Clavulanic acid) was considered the safest antimicrobial by n = 45 (60.8%) respondents whereas Acetaminophen as the safest analgesic by n = 66(89.2%) respondents. Conclusion:This study concluded that there was a lack of knowledge among obstetricians regarding oral health care of the pregnant patients and this study emphasized the need for oral health care awareness among obstetricians.

Objective: To evaluate the indications of primary cesarean section in multipara and to assess the obstetric outcome including maternal, fetal morbidity and mortality, perinatal outcome. Study Design and Setting: It was a hospital based study of primary caesarean sections (CS) done on multiparous patients in duration of two years between January 1, 2016, and December 2017 at Jinnah medical college hospital Karachi. Methodology: Multiparous patients were those who had delivered through vaginal route one or more times (i.e. 28 weeks of gestation or above) or had 1–4children and grand-multiparous are those who had 5 or more children. All the cases included in the study were hospital based and cesarean section was decided by specialist. The procedure was performed by registrars and specialists. The selected patients were followed up till they were discharge from the ward with minimum hospital stay of three days. Data was compiled and results were carried out by SPSS version 23. Results: During the two years of study period, the number of total deliveries were 2064. The primary CS rate in multipara was 37.17%. These women have more likely to have an emergency cessarean sections compared to elective i.e. 85% and15%. The mean age of women was 29.5 years, booked cases were 72.5% and unbooked were 27.5%. Regarding indications for cesarean sections, non-progress of labour ranked first 25.5% followed by fetal distress 20%, pre eclampsia 12 % and ante partum hemorrhage 10.5% etc. Increase incidence of morbidity and mortality was seen in patients undergoing cesarean section due to different reasons. Conclusion: Primary caesarean sections in multipara comprise only a small percentage (37.17%) of total deliveries but were related to high maternal and fetal morbidity

Diagnostic Utility Of Various Biomarkers For Prostate Cancer: A Review
Authors: Nomani Beenish Hussain , Alamgir Mohiuddin
Published: December 2021

Prostate carcinoma is one of the most widespread occurring cancers in males and is the second most common cause of cancer related mortality in men around the world. The therapeutic success rate for prostate cancer can be greatly improved if the disease is detected at an early stage. Therefore, a successful therapy depends immensely on the clinical indicators (biomarkers) for early diagnosis and progression of the disease, as well as the prognosis after the clinical intervention. Despite of its limitations, prostate biopsy is the “gold standard” for diagnosis of prostatic carcinoma. Beyond the shadow of doubt, the advent of PSA level has marked a new era for the efficient screening of prostatic lesions, but PSA alone cannot be considered as an authentic tool for diagnosis. Therefore, the use of new imaging techniques and molecular markers are of great importance for an accurate diagnosis of prostate cancer. Recent advances in molecular techniques have provided new tools facilitating the discovery of new biomarkers for prostate cancer. The aim of this review is to examine the current status of prostate cancer biomarkers, with special focus the on their diagnostic utility and therefore determine a panel of two or three markers for the prompt diagnosis of prostatic carcinoma.

The Effects of Visual Feedback on Performance in Heart Rate- and Power-Based-Tasks during a Constant Load Cycling Test
Authors: Dobiasch Martin , Krenn Björn , Lamberts Robert P. , Baca Arnold
Published: December 2021

Performance feedback can be essential for cyclists to help with pacing their efforts during competitions and also during standardized performance tests. However, the choice of feedback options on modern bike computers is limited. Moreover, little research on the effectiveness of the currently used feedback methods is available. In this study, two novel feedback variants using a bar or a tacho to visualize targets and deviation from targets were compared to a classic design using only numbers. Participants (6 female and 25 male trained to well-trained athletes) completed a protocol consisting of three heart rate-based tasks and one power-based task. The displays were compared with respect to their ability to guide athletes during their trials. Results showed lower root mean square error (RMSE) of the novel variants, but no significant effect of feedback variant on RMSE was found for both tasks (p > 0.05). However, when comparing the feedback variants on a person to person basis, significant differences were found for all investigated scenarios (p < 0.001). This leads to the conclusion that novel feedback variants can improve athletes’ ability to follow heart rate-based and power-based protocols, but even better results might be achieved by individualizing the feedback.
La inseguridad alimentaria, la malnutrición y la obesidad: desde el enfoque de las capacidades
Authors: Arias Díaz Lorena
Published: December 2021

La inseguridad alimentaria, la malnutrición alimenticia y la obesidad, principalmente infantil, se han convertido en tres grandes problemas de salud pública, que requieren una atención urgente e inmediata. Sin embargo, aunque existen diversos programas dirigidos a la disminución o control de dichas situaciones problemáticas, la realidad es que, no se ha logrado un impacto positivo ni en lo cuantitativo ni en lo cualitativo. Es por esta razón, que consideramos el enfoque de capacidades propuesto por Amartya Sen, como una posible alternativa, para posteriores políticas públicas y sociales, encaminadas a la compensación de ciertas incapacidades alimentarias de gran parte de la población mexicana.

Authors: Torres Pineda Ariel José , Mosquera Castillo Aslie Vanessa , Maza Avila Francisco Javier
Published: December 2021

Este artículo tiene como objetivo analizar la percepción entre estudiantes universitarios colombianos sobre la veracidad de la información que consumen en las redes sociales, en función de la tipología de noticias, la frecuencia de consumo y las fuentes de acceso. Para tal fin, se diseñó y aplicó un cuestionario, mediante la técnica de encuesta virtual, a una muestra de 191 estudiantes del área de las Ciencias Económicas de una universidad pública de la ciudad de Cartagena de Indias (Colombia), seleccionados de manera aleatoria, siguiendo un muestreo estratificado, con un nivel de confianza del 95% y un error muestral del 6,5%. Los resultados muestran que es común que los estudiantes universitarios acudan a Facebook o WhatsApp para consultar noticias y, en su proceso de búsqueda, puedan identificar entre 2 y 3 noticias falsas, en promedio. Sólo un grupo reducido afirma haber compartido información falsa con la finalidad de sátira o broma, aunque un porcentaje importe de ellos desconoce si, en algún momento, compartió información sin saber que era falsa. Ante los resultados anteriores, se sugiere que las instituciones universitarias, dentro de sus programas de Bienestar Universitario, formulen estrategias que contribuyan al fortalecimiento de las competencias de los estudiantes para la identificación y manejo eficiente de contenidos falsos en medios digitales, reduciendo así su vulnerabilidad frente a ellas.

TĖVŲ, AUGINANČIŲ IKIMOKYKLINIO AMŽIAUS SPECIALIŲJŲ UGDYMOSI POREIKIŲ VAIKUS, PEDAGOGINIS ŠVIETIMAS SIEKIANT PARTNERYSTĖS SU MOKYTOJAIS
Authors: Klizaitė Jūratė , Varneckienė Aniuta , Valaitienė Aurelija
Published: December 2021

Straipsnyje teoriškai ir praktiškai pagrindžiamas tėvų, auginančių ikimokyklinio amžiaus specialiųjų ugdymosi poreikių vaikus, pedagoginis švietimas bei jo aktualumas, siekiant partnerystės su mokytojais. Tėvų ir mokytojų bendradarbiavimas, grįstas abipuse partneryste yra reikalingas ir reikšmingas vaikui su specialiaisiais ugdymosi poreikiais, kuris aprėpia suinteresuotus ugdymo dalyvius, galinčius nulemti ugdymo  proceso sėkmingumą. Partnerystė – ugdymo dalyviai (tėvai, mokytojai, švietimo pagalbos specialistai ir kt.) yra atviri vieni kitiems, geranoriškai derina savo požiūrius į vaiko ugdymą, tariasi dėl ugdymo tikslų, turinio, vaiko poreikių tenkinimo būdų. Geras bendravimas ir tarpusavio ryšys yra esminis tikros partnerystės bruožas.Tyrimo rezultatai atskleidžia, jog tėvų, auginančių ikimokyklinio amžiaus specialiųjų ugdymosi poreikių vaiką,  požiūriu, poreikis pedagoginiam švietimui siekiant partnerystės yra aktualus, tačiau labai dažnai jis suprantamas kaip tradicinis jų informavimas apie vaiko ugdymą, o ne bendrų veiklų organizavimas, grįstas dialogiškumu ir refleksija. Labai dažnai vyrauja tradicinės tėvų informavimo formos: bendri susirinkimai, individualūs pokalbiai su grupės pedagogu, informacija pateikiama stenduose.Visiems tėvams priimtiniausios pedagoginio švietimo formos yra individualūs pokalbiai su švietimo pagalbos specialistais ir jų konsultacijos.Tyrimas atskleidė, jog ikimokyklinio ugdymo įstaigoje vyksta nuolatinė tėvų komunikacija su pedagogais, tačiau jiems  dar labai trūksta nuoseklesnės informacijos apie vaiko pasiekimus, vaiko savijautą, reikalingi  praktiniai patarimai. Dažiausiai taikomos pedagoginio švietimo formos – individualūs pokalbiai, konsultacijos, kurios padeda suprasti vaiko raidos, ugdymo sunkumus. Poreikis bendradarbiauti, kuris būtų paremtas partneryste yra didžiulis, tačiau tėvai pageidautų iš pedagogų  daugiau iniciatyvos.Tik intensyvus bendradarbiavimas ir partnerystė su tėvais gali užtikrinti  kokybišką specialiųjų ugdymosi poreikių vaikų ugdymą.

Authors: Kustienė Aurelija
Published: December 2021

Per pastaruosius kelerius metus vidaus auditas tapo ypač įtakinga įmonės funkcija, nustatančia pagrindines rizikas, patariančia sprendimus priimantiems asmenims ir taip kuriančia pridėtinę vertę įmonei. Šį vidaus audito vaidmenį padidino pasaulinė Covid-19 pandemija ir jos poveikis ekonomikai bei įvykiai, trikdantys daugelį procesų ir keliantys didelę riziką.

Atliekant tyrimą keliamas probleminis klausimas: kokios vidaus audito veiklos ir kaip jos sukuria pridėtinę vertę įmonei? Tyrimo tikslas – atskleisti besikeičiantį vidaus audito vaidmenį kuriant pridėtinę vertę ir pateikti rekomendacijas jos didinimui. Tyrimo metodai: mokslinės ir norminės literatūros apžvalga, analizė ir sisteminimas, palyginimas, loginė analizė ir apibendrinimas. Siekiant atskleisti besikeičiantį vidaus audito vaidmenį apžvelgiami 20 metų laikotarpio atlikti moksliniai tyrimai ir pastarųjų metų audito praktikų įžvalgos.

Pagrindiniai tyrimo rezultatai: atskleistas besikeičiantis vidaus audito vaidmuo nuo tradicinių funkcijų vykdymo iki inovatyvių metodų taikymo vidaus audito veikloje siekiant sukurti pridėtinę vertę įmonei; nustatyti kylantys vidaus audito iššūkiai kilus pasaulinei Covid-19 pandemijai; identifikuotos pagrindinės vidaus audito rizikos; atskleistos naujos vidaus audito tendencijos ir  pateiktas naujos kartos transformacijas spartinančių strategijų vidaus audito modelis.

Pagrindinės išvados: besikeičiantis vidaus audito vaidmuo reiškia tų pačių tradicinių funkcijų (užtikrinimo ir konsultavimo) atlikimą taikant inovatyvius metodus, labiau integruojant IT bei naujas strategijas siekiant prisitaikyti prie kylančių rizikų (strateginės, kibernetinio saugumo, duomenų analizės ir valdymo, organizacijos kultūros, žmogiškojo kapitalo valdymo, tvarumo); pateiktas naujos kartos vidaus audito modelis apima tris pagrindinius komponentus (metodiką, valdymą ir įgalinančias technologijas) ir jų veikimą užtikrinančius elementus. Šio modelio taikymas galėtų suteikti įmonėms didesnę pridėtinę vertę, kurios suinteresuotosios šalys tikisi iš vidaus audito.

Published: December 2021

2019 – 2021 metais atliktas Lietuvos imitacinių bendrovių asociacijos užsakytas tyrimas, kurio tikslas buvo atskleisti verslumo ugdymo imitacinėse bendrovėse efektyvumo didinimo galimybes, taikant dalykų integravimą. Tyrimo metodai: analitinė mokslinės literatūros analizė, kiekybinė reprezentatyvi apklausa raštu, statistinė duomenų analizė. Remiantis mokslinės literatūros šaltinių analize, atskleista dalykų integravimo nauda studijų/mokymo procesui. Išanalizavus dalykų integravimo galimybes į IB veiklą, nustatyta, kad dauguma respondentų atsakė, kad jų galima dėstomo/mokomo dalyko integracija į IB veiklą integruotųsi integruotu mokymo lygiu, kai pasirenkama tema apima visas arba daugelį disciplinų. IB veikla apima labai platų įgytų teorinių žinių pritaikomumą praktinėje veikloje, todėl integruojant dalykus integruotu mokymo lygiu rengiant bendras praktines užduotis, būtų aiškesnės tarpdalykinių ryšių sąsajos.

Analizuojant verslumo ugdymo efektyvumo didinimo būdus, taikant dalykų integravimą IB veikloje, buvo išsiaiškinta, kad reikėtų skatinti dėstytojų/ mokytojų tarpusavio bendradarbiavimą, atnaujinant studijų programas, rengiant metodinę medžiagą ir bendras praktines užduotis, reikėtų įtraukti darbdavius ir socialinius partnerius, lankytis tikrose verslo įmonėse ar kviesti verslo atstovus į paskaitas/pamokas ir nagrinėti praktines situacijas. Būtų galima pasiūlyti mokymo institucijose kurti bendrą su kitais dalykais integruotą virtualią aplinką, kurioje būtų pateikiama metodinė medžiaga, integruotos užduotys, bendradarbiavimo ir vertinimo priemonių sistema, leidžianti lanksčiai valdyti integruotą studijų procesą, siekiant gerinti mokymosi kokybę, orientuotą į platesnį žinių panaudojimą.

Anatomical constructions in the making of the nude moldovan sculpture. Approaches in the realm of realism
Authors:   Institute of Cultural Heritage, Republic of Moldova, Marian Ana
Published: December 2021

In Moldovan sculpture, there are two types of the introduction of anatomical structures in the creation of sculptural nudity: based on realism and stylized ones. The pioneer in the study of sculptural nudity was Alexander Plamadeala. Although his studies at the Imperial Academy of Art, Sculpture and Architecture allowed him to comprehensively approach the depiction of sculptural nude, the sculptor still continued to experiment and seek new ways in the description of nude. “Nude” in Yuri Kanashin’s interpretation is an integral part of thematic compositions and has a separate logic, subordinated to the author’s sensitivity. Anatomical interpretation in Ion Zderciuk’s works is the starting point for realistic forms which transform into stylized ones, where metaphor takes the leading place and the solutions are innovative. Interpretations of sculptural nudity involve long-term training, knowledge of the anatomy of the skeleton and musculature, the proportions of the human body. Based on this, the sculptors practiced stylization, always different in artistic manners, but which represented a new vision of the interpretation of sculptural nudity in Moldovan plastic art.
The historical-biographical film: destinies and personalities
Authors:   Institute of Cultural Heritage, Republic of Moldova, Olarescu Dumitru
Published: December 2021

The history of national cinema shows that the evolution of non-fiction biographical film began with subjects dedicated to prominent personalities. These were included in the film magazine “Soviet Moldova” and in the almanac “Life in pictures”. In 1961, the first historical-biographical film “The Legendary Brigade Commander”- a eulogy to Grigore Kotovski (director A. Litvin) appeared at the “Moldova-film” studio, followed by other films dedicated to the heroes of the times: Pavel Tkacenko, Elena Sârbu, Tamara Cruciok, which were dominated by a pronounced propagandistic character. A new level of national historical-biographical film can be noticed in the late 1960s and early 1970s, when the filmmakers: Emil Loteanu (“Academician Tarasevici”), Andrei Buruiană (“Ştefan Neaga”), Vlad Druc (“Ion Creangă”) made their debut. Yet, the idea of biography especially predominates in the creation of Anatol Codru, who played a significant role in the affirmation stage of this kind of nonfiction film, bringing through his films, “Alexandru Plămădeală”, “Alexei Şciusev”, “Dimitrie Cantemir”,”Vasile Alecsandri” a new breath in the context of the films made before him. He imposed himself through a poetic-philosophical vision on the destinies and the creation of the personalities, who contributed to the spiritual prosperity of the nation.
Issues of musical semantics of F. Chopin in the context of the era of romanticism
Authors:   Academy of Music Theatre and Fine Arts, Republic of Moldova, Melnic Tamara , Usaciov Alexei ,   Academy of Music Theatre and Fine Arts, Republic of Moldova
Published: December 2021

The study of works of the Romanticism period and the formation of appropriate ideas about the romantic musical style is an effective way to activate the creative thinking of young professional musicians, stimulates their artistic initiative, and makes up for the shortcomings of the technological approach. Thus, the performer gets the opportunity to realize the correct reading of the musical text, resourcefully participates in the creation of his own parts and makes stylistically competent interpretations. The creation of F. Chopin had an undoubted influence on the creation of the figurative and meaningful image of the era in which the composer lived. Using some aspects of the method of semantic analysis, the authors of the article tried to consider some features of Chopin’s musical thinking and discover the relationship between the complex of expressive means used by the composer and the meanings expressed by them, thus trying to achieve a more in-depth understanding of the style of Romanticism.
Reflection of the events of the “Balkan” period in the Gagauz fiction
Authors:   Institute of Cultural Heritage, Republic of Moldova, Nicoglo Diana
Published: December 2021

The most detailed description of the “Balkan” period is found in the novel by D. Tanasoglo “Uzun Kervan”. In other genres (poetry), the poeticized image of the Balkans as the historical homeland of the Gagauz is presented to a greater extent. The main events of the “Balkan” period in the history of the Gagauzians, reflected in fiction, are: the adoption of Christianity by the Oghuz / Uzes – the ancestors of the Gagauzians, relations with the local population of the Balkans, the struggle against the Ottoman Turks, and the creation of a fictional Gagauz state called Uzi Eyalet. The authors also draw attention to the way in which changes occur in the traditional everyday culture of ancestors of the Gagauz as a result of changing economic-cultural type, and religion. In the Gagauz environment of creative people, there is a unity in the perception of the historical past associated with the presence of the ancestors of the Gagauz people in the Balkans. As a rule (with a few exceptions), the past broadcast by Gagauz writers is largely mythologized: and the writers themselves play a significant role in the process of constructing ethnicity.

Bio-inspired hierarchical metamaterials
Authors: Miniaci Marco
Published: December 2021

Nature has engineered complex designs to achieve advanced properties and functionalities over hundreds of thousands of years. For instance, a hierarchical organization over multiple length scales allows enhanced quasistatic mechanical properties (such as high specific strength, stiffness, and toughness). While largely investigated in the quasistatic domain, the role of hierarchy in the dynamic behaviour of metamaterials remains largely unexplored. In this webinar a numerical and experimental investigation of the influence of bio-inspired hierarchical organization on the wave dispersion diagram in metamaterials with self-similar structures at various spatial scales is presented. The advantages (and limitations) that the hierarchical architectures provide for the dynamic performance with respect to conventional metamaterials will be discussed.
Surprising acoustic propagation in foams: from liquid to solid
Authors: Pierre Juliette
Published: December 2021

Liquid and solid foams present surprising acoustic properties.
A liquid foam is a complex gas-liquid system with a low liquid fraction (<30%). Its rigidity is due to a liquid skeleton, containing the most important part of the liquid and linked by thin liquid films. The bubble size distribution is strongly polydisperse.
Over the past years we investigated, in a large frequency range, how a liquid foam behaves when insonified. We showed that liquid foams act as natural and 3D isotropic acoustic metamaterials. Moreover, this work confirmed that liquid foams have important soundproofing properties. First, I will show you how an acoustic wave propagates and dissipates when it travels through a collection of thin liquid films loaded by the surrounding air and a massive liquid skeleton.
More recently, we investigated the case of solid foams elaborated by solidification of liquids foams and where the entire liquid skeleton (even films) has been preserved. In this second part, I will show you that the presence of very thin membranes is far from being a handicap to blocking sound.
Resonant States for Scattering Problems: Killing Mie Softly
Authors: McPhedran Ross
Published: December 2021

This talk deals with issues common to those addressed by David Bergman, in that the topic is certain difficulties associated with complex resonant states encountered in scattering problems. These difficulties arise when one wishes to evaluate normalisation integrals and inner products for these states, which have rapid oscillations and diverging amplitudes at large dis- tances from the scatterer. Rather than using numerical treatments, the method presented here is analytic in nature, and relies on results of distri- bution theory. The method can yield closed form expressions for integrals over an infinite range involving the product of two Bessel functions of the same or different types, combined with a power of the radial distance. The essential point is that for rapidly oscillating functions with mean zero, the contribution to the integrals from the infinite upper limit is zero, despite the diverging amplitudes (equivocation trumps exaggeration).
Dynamics of waves in continuum honeycomb structures
Authors: Weinstein Michael I
Published: December 2021

We overview results on the dynamics of waves (e.g. Schroedinger and Maxwell equations) in honeycomb structures and their deformations.
We study phenomena which arise from the presence of Dirac (conical) points in the bulk band structure.
These include the existence of robust edge (interface) states, which localize along certain sharp terminations, and along domain walls.
We then discuss recent work on the emergence of pseudo-magnetic fields in non-uniformly deformed honeycomb structures.
We apply these results to predict Landau-like energy levels in photonic crystals, and present numerical confirmation of the theory.
Wave Interaction with Subwavelength Resonators
Authors: Ammari Habib
Published: December 2021

In this lecture, the speaker reviews recent results on subwavelength resonances. His main focus is on developing a mathematical and computational framework for their analysis. By characterizing and exploiting subwavelength resonances in a variety of situations, he proposes a mathematical explanation for super-focusing of waves, double-negative metamaterials, Dirac singularities in honeycomb subwavelength structures, and topologically protected defect modes at the subwavelength scale. He also describes a new resonance approach for modelling the cochlea which predicts the existence of a travelling wave in the acoustic pressure in the cochlea fluid and offers a basis for the tonotopic map.
Ultrasound self-assembly of small particle patterns in a fluid
Authors: Vasquez Fernando Guevara
Published: December 2021

Standing ultrasound waves can be used to steer small particles suspended in a fluid into user defined patterns. If the fluid is e.g. a resin that can be cured, this technique can be used to fabricate materials with a custom microstructure. We start with the idealized case of infinitely many ultrasound transducers in the far-field to establish that the particle patterns are expected to be diffraction-limited. Then we move on to the patterns that can be obtained by N parallel pairs of transducers in the far-field. If N is equal to the dimension, the particles arrange in periodic patterns, with the caveat that only a subset of the possible crystallographic symmetries are achievable with this method. If N is larger than the dimension, the particles arrange in quasiperiodic patterns that can be rotated, translated, etc. by adjusting the amplitudes and phases of the ultrasound transducers.
Metasurfaces for light shaping: a look into the past to better appreciate the present and future
Authors: Lalanne Philippe
Published: December 2021

In integrated circuits, an important prerequisite for success is that every transistor can be driven or read independently, and nanotechnology is used to push the integration limit subject to that essential requirement. In dielectric metasurfaces for wavefront shaping, one aims to imprint spatially varying phases (or amplitudes, polarizations) on an incoming optical beam, and nanotechnology is used to spatially control the phase down to the subwavelength scale, as required for high numerical aperture focusing or imaging, beam steering over large angles, and computer-generated holography. Just like for integrated circuits, it is important that the phase can independently be controlled by adjacent nanostructures (or meta-atoms).
This demanding requirement has marked the history of diffractive optics. I will review this history, evidence some fundamental limitations and introduce recent prospects in my group in relation to disordered metasurfaces.
Longitudinal electromagnetic waves with extremely short wavelength
Authors: Belov Pavel
Published: December 2021

Elastic waves may have either longitudinal or transverse polarization: the acoustic (compression) waves are longitudinal while the sheer stress waves are usually transverse. The electromagnetic waves are in many aspects similar to the elastic ones. However, the electromagnetic waves in vacuum and most materials have transverse polarization. Longitudinal electromagnetic waves with electric field parallel to wave vector are very rare and appear under special conditions in a limited class of media, for example in plasma.

In this work, we study the dispersion properties of an easy-to-manufacture metamaterial consisting of two three-dimensional cubic lattices of connected metallic wires inserted one into another, also known as an interlaced wire medium. It is shown that the metamaterial supports longitudinal waves at extremely wide frequency band from very low frequencies up to the Bragg resonances of the structure.

The waves feature unprecedentedly short wavelengths comparable to the period of the material.

The revealed effects highlight spatially dispersive response of interlaced wire medium and provide a route toward generating electromagnetic fields with strong spatial variation.
Towards scalable Photonic Neural Networks with (3+1)D integrated optics
Authors: Brunner Daniel
Published: December 2021

Integrated photonic architectures have the potential to revolutionize neural network computing. However, conventional 2D lithography strongly limits the size of integrated photonic neural networks due to fundamental scaling laws. We want to overcome this problem by integrating neural networks using 3D printed photonic waveguides. For that we demonstrate complex 3D multimode waveguide networks based on polymer waveguides surrounded by air. Furthermore, we recently developed a (3+1)D direct laser writing technique where we dynamically and locally control the writing power in order to realize single mode step or graded index waveguides.
New Trends Towards Seismic Metamaterials
Authors: Roux Philippe
Published: December 2021

We report on a seismic metamaterial experiment in a pine-tree forest environment where the dense collection of trees behaves as subwavelength coupled resonators for surface seismic waves. For the METAFORET experiment, more than 1000 seismic sensors were deployed over a 120 m × 120 m area to study the properties of the ambient and induced seismic wavefield that propagates in the ground and in trees. The goal of the experiment was to establish a link between seismic-relevant scales and microscale and mesoscale studies that pioneered the development of metamaterial physics in optics and acoustics. The first results of the METAFORET experiment show the presence of frequency band gaps for Rayleigh waves associated with compressional and flexural resonances of the trees, which confirms the strong influence that a dense collection of trees can have on the propagation of seismic waves.
Nonlinear Waves and Flexible Elastic Metamaterials
Authors: Tournat Vincent
Published: December 2021

Flexible elastic metamaterials can be described as artificial structures, designed to be highly compliant and capable of withstanding large elastic deformations. Their current significance lies in the fact that they possess a number of unusual properties that can be controlled and, in addition, they belong to an extremely large design space. While their static character has been widely studied, their dynamic properties are still in their early stages, especially with regard to their non-linear dynamics. Nevertheless, we recall here that these non-linear properties can be designed in a rational way, allowing the development of metamaterials for the control of large amplitude elastic waves [1-5]. In this context, I synthesize in this talk a set of our recent results on the propagation of nonlinear waves in these flexible elastic metamaterials [1-10], and I will draw up possible perspectives from these initiated directions, ranging from vibration control, toy models for fundamental wave physics, to possible practical applications.
Mechanics and dynamics of two-dimensional quasiperiodic composites
Authors: Ruzzene Massimo
Published: December 2021

Periodic configurations have dominated the design of phononic and elastic-acoustic metamaterial structures for the past decades. Unlike periodic crystals, quasicrystals lack translational symmetry but are unrestricted in rotational symmetry. This provides the opportunity to investigate novel classes of quasicrystal inspired elastic composites whose mechanical static and dynamic properties are largely unexplored. This presentation illustrates the performance of continuous elastic quasicrystals composites, here denoted as quasiperiodic (QP) composites, characterized by different rotational symmetry orders which is directly enforced through a design procedure in reciprocal space. Static mechanical properties are investigated as a function of symmetry order and filling fraction. Results indicate that higher order symmetries, such as 8-, 10- and 14-fold, lead to equivalent stiffness characteristics that interpolate those of the constituent materials while maintaining high levels of isotropy for all filling fractions. Thus, QP composites exhibit more uniform strain energy distributions when compared to periodic 4-fold and 6-fold symmetric configurations. Similarly, nearly-isotropic wave propagation is observed over a broader range of frequencies. The spectral dynamic properties are also investigated by enforcing rotational symmetry constraints in a wedge-type unit cell, which allows for the estimation of bandgaps, whose presence is confirmed in frequency response computations. Wave directionality and bandgaps are also estimated through parallel studies conducted on plate structures characterized by QP patterns of surface stubs. These experiments show clear bandgaps, illustrate how wave fronts reflect the rotational symmetry of the domains, and demonstrate that higher order geometries lead to isotropic propagation over a broader range of frequencies. The investigations presented herein open avenues for the general exploration of the properties of quasiperiodic media, with potentials for novel architectured material designs that expand the opportunities provided by periodic media.

Now days, in many real life applications, the sentiment analysis plays very vital role for automatic prediction of human being activities especially on online social networks (OSNs). Therefore since from last decade, the research on opinion mining and sentiment analysis is growing with increasing volume of online reviews available over the social media networks like Facebook OSNs. Sentiment analysis falls under the data mining domain research problem. Sentiment analysis is kind of text mining process used to determine the subjective attitude like sentiment from the written texts and hence becoming the main research interest in domain of natural language processing and data mining. The main task in sentiment analysis is classifying human sentiment with objective of classifying the sentiment or emotion of end users for their specific text on OSNs. There are number of research methods designed already for sentiment analysis. There are many factors like accuracy, efficiency, speed etc. used to evaluate the effectiveness of sentiment analysis methods. The MapReduce framework under the domain of big-data is used to minimize the speed of execution and efficiency recently with many data mining methods. The sentiment analysis for Facebook OSNs messages is very challenging tasks as compared to other sentiment analysis because of misspellings and slang words presence in twitter dataset. In this paper, different solutions recently presented are discussed in detail. Then proposed the new approach for sentiment analysis based on hybrid features extraction methods and multi-class Support Vector Machine (SVM). These algorithms are designed using the Big-data techniques to optimize the performance of sentiment analysis
