Quantifying unequal urban resilience to rainfall across China from location-aware big data
Authors: Qian Jiale , Du Yunyan , Yi Jiawei , Liang Fuyuan , Wang Nan , Ma Ting , Pei Tao
Published: January 2023

Abstract. Disaster-relevant authorities could make uninformed decisions due to the lack of a clear picture of urban
resilience to adverse natural events. Previous studies have seldom examined the
near-real-time human dynamics, which are critical to disaster emergency
response and mitigation, in response to the development and evolution of
mild and frequent rainfall events. In this study, we used the aggregated
Tencent location request (TLR) data to examine the variations in collective
human activities in response to rainfall in 346 cities in China. Then two
resilience metrics, rainfall threshold and response sensitivity, were
introduced to report a comprehensive study of the urban resilience to
rainfall across mainland China. Our results show that, on average, a
1 mm increase in rainfall intensity is associated with a 0.49 % increase
in human activity anomalies. In the cities of northwestern and
southeastern China, human activity anomalies are affected more by rainfall
intensity and rainfall duration, respectively. Our results highlight the
unequal urban resilience to rainfall across China, showing current heavy-rain-warning standards underestimate the impacts of heavy rains on residents in the northwestern arid region and the central underdeveloped areas
and overestimate impacts on residents in the southeastern coastal
area. An overhaul of current heavy-rain-alert standards is therefore needed
to better serve the residents in our study area.
Design optimization of offshore wind jacket piles by assessing support structure orientation relative to metocean conditions
Authors: Mroczek Maciej M. , Arwade Sanjay Raja , Lackner Matthew A.
Published: January 2023

Abstract. The orientation of a 3-legged offshore wind jacket structure in 60 meter water depth, supporting the IEA 15MW reference turbine, has been assessed for optimizing the jacket pile design. A reference site off the coast of Massachusetts was considered, including site specific metocean conditions and realistically plausible geotechnical conditions. Soil-structure interaction was modelled using three dimensional FE ground-structure simulations to obtain equivalent mudline springs which were subsequently used in nonlinear elastic simulations, considering aerodynamic and hydrodynamic loading of extreme sea states in the time domain. Jacket pile loads were found to be sensitive to the maximum 50 year wave direction, as opposed to the wind direction, indicating that the jacket orientation should be considered relative to the dominant wave direction. The results further demonstrated that the jacket orientation has a substantial impact on the overall jacket pile mass and maximum pile embedment depth, and therefore represents an important opportunity for project cost and risk reductions. Finally, this research highlights the importance of detailed knowledge of the full global model behavior (both turbine and foundation) for capturing this optimization potential, particularly due to the influence of wind-wave misalignment on pile loads. Close collaboration between the turbine supplier and foundation designer, at the appropriate design stages, is essential.

Panser et re(penser) les imaginaires de la colonisation dans Frère d’âme de David Diop
Authors: Konan Richmond Alain
Published: January 2023

L’histoire coloniale ne peut faire l’économie de l’épisode des tirailleurs Sénégalais durant la première Guerre Mondiale. A ce propos, les silences et les ambiguïtés de cette guerre asymétrique, mais également, l’infortune des soldats africains engagés dans cette immense tragédie planétaire sont au centre de préoccupations mémorielles. A travers Frère d’âme de David Diop, la présente étude interroge les silences et la  propagande de guerre orchestrée contre les tirailleurs africains, sur la base de préjugés raciaux. L’approche postcoloniale d’Achille Mbembé constitue l’outillage méthodologique de cette réflexion tripartite qui explore les sources d’une mémoire coloniale controversée, s’attarde sur la nécessité de panser les imaginaires coloniaux par une déconstruction de la « bibliothèque coloniale » et enfin, insiste sur la construction d’une mémoire afrocentrée de la Grande Guerre.
(Re)penser les frontières des identités dans les littératures, musiques et cinémas francophones
Authors: Konan Richmond Alain , Lattro Tite , Anzoumana Sinan
Published: January 2023

Résumé: Cet ouvrage se propose de questionner l’espace littéraire francophone sur les mutations identitaires complexes et multiples en cours. Mais surtout, analyser la possibilité de construction d’un monde qui refuse de symboliser uniquement l’« autre », au profit de « l’entre-deux » ou du « Tout-monde ». En se fondant sur la pensée de Franz Fanon, Edouard Glissant, Achille Mbembé, d’Olympe de Gouges et ses épigones féministes etc., cet ouvrage interrogera les nouvelles dynamiques identitaires et mettra en débat les frontières au cœur de la cartographie des identités. Le présent ouvrage est composée de 12 contributions interdisciplinaires, classées en 4 axes thématiques.  

La section initiale qui se focalise sur le trauma colonial et les voies d’une reconstruction identitaire du sujet postcolonial africain s’ouvre avec l’article de Konan Richmond Alain qui analyse Frère d’âme de David Diop, sous l’angle d’une conscience mémorielle afrocentrée. 

La deuxième partie concentre des textes qui mettent en relief la confrontation des identités en contexte (trans) migratoire. 

La troisième section s’intéresse aux manifestations identitaires dans les arts, musiques et cinéma. 

L’ultime articulation s’intéresse aux mythes qui traduisent les imaginaires et les identités des peuples.
Relire Adiaffi sous le prisme de la désidentitsation
Authors: Lattro Tite
Published: January 2023

Dès sa parution la critique littéraire africaine a salué La carte d’identité de Jean-Marie Adiaffi comme un texte majeur qui insuffle un « nouveau frisson » à la littérature africaine. Si la qualité de ce texte n’est plus à discuter, certaines orientations analytiques dont il a fait l’objet le sont encore moins, sans doute influencées par des découpages générationnels qui tentent de soumettre la lisibilité du roman africain à la pesanteur de l’histoire ou à confiner l’analyse dans un moule. En effet, pour une bonne part des réflexions, ce texte se présente comme un lieu de (con)quête identitaire. Si nous pouvons admettre que l’enjeu identitaire y est central, nous postulons toutefois, à contre-courant de ces analyses, que ce qui se joue réellement dans ce texte n’est pas l’affirmation d’un « je », mais bien au contraire sa crise, qui aboutit à une écriture de la dépersonnalisation et de la désidentisation. Ainsi, à partir d’une démarche déconstructiviste, la présente analyse se propose de montrer que le récit de Jean-Marie Adiaffi est hanté par une sorte de symbole thériomorphique exprimé sous les traits de l’impuissance et de la dépossession qui charrie d’une façon ou d’une autre une économie de la stérilité, de la perte de soi et de la néantisation.

LOGICAL ALLUSIONS IN THE PLOTS OF SCI-FI AND FICTION: FROM ABRAHAM’S DILEMMA TO NEWSPEAK
Authors: Михайлов Кирилл Авенирович
Published: January 2023

В настоящей работе представлены различные кейсы, сутью которых является разбор логической подоплеки различных сюжетов фантастической литературы. Для начала разбираются свойства самонесбывающегося пророчества, указываются ситуации, в которых работают его схемы и механизмы («дилемма Авраама», «парадокс хиппи» Р. Смаллиана, «стоическое счастье»; «эффект анальгина», «эпистемический кошмар» и др.). Далее предлагается применить сюжет «возвращение со звезд» С. Лема к анализу ускорения социальных процессов в настоящее время. Третий важный блок работы образует семантический рассказ (относительно феномена «выразительные возможности языков») о концепции понятия Г. Шахназарова, «мифе о пещере» Платона и «новоязе» Дж. Оруэлла.

The present paper presents various cases whose essence is the analysis of the logical background of various subjects of sci-fi and fantasy. To begin, I investigate the properties of self-unfulfilling prophecies and point out the situations in which its schemes and mechanisms are involved (Abraham’s Dilemma, Smullyan’s Hippie’s Paradox, “stoic happiness”; the “anaesthetic effect”, the “epistemological nightmare”, etc.). Next, I propose to apply the plot of “return from the stars” by Stanisław Lem to the analysis of the present-day acceleration of social processes. The third important block of the paper is formed by a semantic story (regarding the phenomenon of the expressive power of languages) about Georgy Shakhnazarov’s notion of concept, Plato’s myth of the cave and Orwell’s Newspeak.
PERFORMATIVE INTERPRETATION OF A DEDUCTIVE ARGUMENT: HINTIKKA SAYS “YES”, WALTON SAYS “IT MIGHT BE”, I SAY “NOT QUITE YET”
Authors: Карпов Глеб Викторович
Published: January 2023

В статье ставится вопрос о существовании аргументов особого типа - так называемых перформативных аргументов. На примере перформативной интерпретации рассуждения cogito ergo sum, которую предложил Хинтикка, вскрываются все сложности такого подхода. Так, устанавливается, что определения экзистенциального и перфрмативного противоречий, выполняющие функцию драйверов перформативных аргументов, семантически некорректны. Показано, что применение логики действий отчасти исправляет ситуацию, хотя и не позволяет выяснить отличительные особенности аргументов перформативного типа. Делается вывод о том, что, для того чтобы дать описание перформативному аргументу, нужно использовать семантики, альтернативные реляционным.

The article questions the existence of the so-called performative arguments. On the example of Hintikka’s performative interpretation of the cogito ergo sum dictum, all the complexities of such an approach are revealed. I claim that the definitions of an existential and the performative contradiction, which serve as drivers of performative arguments, are semantically incorrect. Then I show that the application of the logic of actions partially improves the situation, although it does not allow to clarify the distinctive features of the performative arguments. I conclude that in order to describe performative arguments, it is necessary to use semantics other than conventional relational semantics.
A SEMIOTIC CONCEPTION OF THE SELF IN SUSAN PETRILLI’S SEMIOETHICS
Authors: Станжевский Федор Алексеевич
Published: January 2023

Статья посвящена диалогической концепции самости, которую разрабатывает в своей семиоэтике австрало-итальянская философ Сьюзан Петрилли. Семиоэтика основана на ряде принципов - в частности, на установке слушания другого и открытости по отношению к знакам инаковости. Семиоэтика призвана служить критической инстанцией культуры, и одной из главных ее задач является критика субъективности. Вместо субъективности, основанной на четко очерченной и статичной идентичности, семиоэтика предлагает динамическую и диалогическую концепцию самости, основанную на уподоблении самости знаку. Знак по своей природе отсылает к иному, чем он сам, и участвует в сети или цепочке отсылок; следовательно, и самость является не замкнутой в себе изолированной сущностью, но динамическим процессом, открытым инаковости.

The article addresses the dialogic conception of the self, elaborated by the Australian-Italian philosopher Susan Petrilli in her semioethics. Semioethics rests on a number of principles - in particular, on the attitude of listening to the other and openness towards the signs of otherness. Semioethics is intended to serve as a critical instance of culture, and one of its principal objectives is putting subjectivity to question. Instead of subjectivity based on a neatly delineated and static identity, semioethics suggests a dynamic and dialogical conception of the self, based on likening the self to a sign. Signs by their nature refer to something other than themselves, they participate in a chain or a network of deferrals; therefore the self is not a self-enclosed and isolated entity, but rather constitutes a dynamic process open to otherness.
PHILOSOPHY FROM THE FIRST PERSON. CHRISTINE DE PIZAN: THE BOOK OF THE CITY OF LADIES
Authors: Косякова Валерия Александровна
Published: January 2023

Кристина Пизанская - уникальная мыслительница позднего Средневековья, заговорившая о проблемах женской интеллектуальной культуры, равноправия и мизогинии. Она поднимала вопросы, связанные с женским образованием и спецификой конструирования стереотипов в патриархальном дискурсе. Автобиографический стиль философствования от первого лица - важный прием ее письма, не только конструирующий память-о-себе, но и становящийся приемом редуцирования мужского пристального взгляда в текстуальной культуре. Анализ феномена ее философствования неотделим от фактов биографии и ее конструирования в женском нарративном письме.

Christine de Pizan is a unique thinker of the Late Middle Ages, who spoke about the problems of female intellectual culture, equality and misogyny. She raised issues related to women’s education and the peculiarities of stereotype construction in patriarchal discourse. The autobiographical style of philosophizing from the first person is an important method of her writing, constructing not only a memory-about-her-self but also becoming a method of reducing the male gaze in textual culture. An analysis of the phenomenon of her philosophizing is inseparable from the facts of her biography and its construction in women’s narrative writing.
LOGICAL ANALYSIS OF SYMBOLIC CONCEPTION REPRESENTATION IN TERMINOLOGICAL SYSTEMS
Authors: Badie Farshad
Published: January 2023

Cognitive, or knowledge, agents, who are in some way aware of describing their own view of the world (based on their mental concepts), need to become concerned with the expressions of their own conceptions. My main supposition is that agents’ conceptions are mainly expressed in the form of linguistic expressions that are spoken, written, and represented based on e.g. letters, numbers, or symbols. This research especially focuses on symbolic conceptions (that are agents’ conceptions that are manifested in the form of their symbols). I attempt to logically (and using CLSYM) analyse symbolic conceptions in terminological systems. CLSYM is an assertional fragment of my developed Conception Language (CL), which is utilised as a formal-logical system for representing and explicating agents’ conceptions of the world.
PHENOMENOLOGICAL SEMIOTICS OF MYTH AND PARABLE
Authors: Воинов Александр Валерьевич
Published: January 2023

Предлагается семиотическая модель коллективно разделяемой апперцепции, основанная на идеях М. Мерло-Понти о роли общего интенционального объекта в со-конституировании эго и альтер-эго и обеспечиваемой этим феноменологии коллективной деятельности. В качестве формальной семиотической модели в статье используется теория Фоконье, обобщающая схему противопоставления пространств «оболочки» и «содержания» в метафоре на случаи, где выход за пределы «рационального» достигается путем «склейки» элементов пространства. Это позволяет переосмыслить понятие вторичной знаковой системы и ее роли в таком явлении, как социальный миф, и предложить тезис: миф есть притча с табуированной достоверностью.

A semiotic model is proposed for a collectively shared apperception basing upon Maurice Merleau-Ponty’s ideas about the role of the shared intentional object in the co-constitution of Ego and Alter Ego and of the collective activity supported by a phenomenology of that kind. Fauconnier’s theory of conceptual blending is used as a formal semiotic model. It generalises the classical opposition of tenor and vehicle in metaphors onto cases where a more complex transition beyond the sphere of the rational is needed. That allows to revisit the concept of secondary sign system and its role in the social myth, so that the following motto may be proposed: a myth is a parable with tabooed veracity.

True conceptualization is critical in understanding the fundamental principles of general science at the primary level. Concepts developed without prior understanding of the subject are not always wrong, although they might be characterized as misconceptions. The current study was conducted to identify misconceptions in biology part of general science book. Furthermore, it was to analyze the most likely causes of these diagnose misconceptions among primary school students. The current study was a case study. Two-tier diagnostic tests and diagnostic test interviews were employed as study instruments. The 400 fifth-grade students were chosen on purpose as a test sample, and 20 students were chosen for the semi-structured interview that possessed more misconceptions. Thematic analysis was utilized to do a qualitative study of the data. In addition, data triangulation was performed to combine the test and interview results. Language misunderstanding, misinterpretation of prior knowledge and visualization inaccuracy were the main causes for diagnosed misconceptions. It was recommended that a suitable atmosphere for general science learning be provided and that teachers should design learning using the appropriate method, strategy, model, and media to dispel misconceptions in biology part of general science book among primary school students. Keywords: Misconception, general science, primary students, reasons behind misconceptions.
Molecular chirality sensing via parity-time symmetric and general loss-gain systems
Authors: Kafesaki Maria
Published: January 2023

We discuss the potential of combined gain-loss systems, and in particular of parity-time symmetric (PT) systems, to enhance the chiral response of embedded molecular chiral systems, facilitating thus chirality sensing and enantiomer discrimination. Thin molecular chiral layers embedded in properly designed PT-symmetric systems have been found to lead to more than one order of magnitude enhancement of both the attainable circular dichroism (CD) response and the Kuhn’s dissymmetry factor, the latter directly related to the enantio-selectivity of chiral light-matter interactions.
Time-varying and reconfigurable driven photonics
Authors: Sapienza Riccardo
Published: January 2023

Metamaterials have revolutionised the way we control light transport and generation. Yet, to date, they rely on passive architectures, only redistributing incident wave energy - for example in a metalens, or a cloak - with no power to locally absorb or produce it to enhance responses. Here I will discuss our first steps towards driven photonic systems, able to convert energy to function and perform actions.
Asymptotic Analysis of Waveguides: Topological Protection, Homogenisation, Tunability and Quasiperiodicity
Authors: Davies Bryn
Published: January 2023

We present a general approach for studying localised eigenmodes that are created in crystalline media when edges, interfaces and defects are introduced. We will use asymptotic methods to characterise the eigenfrequencies of these modes and will establish a homogenisation regime that can be used to estimate the rate at which they decay away from the defect. Examples of topologically protected modes, such as those based on the famous SSH model, will be used to demonstrate the method. We will see that these concise asymptotic results are invaluable for fine tuning designs, removing the need for expensive numerical optimisation. Finally, we will show how these methods can be extended to quasiperiodic media and will explore the potential advantages of this more challenging setting.
Magneto-Optical Materials with Zero Net Magnetization
Authors: Pyvovar Nazar
Published: January 2023

The key component of nonreciprocal devices, including microwave and optical isolators, circulators, and nonreciprocal phase shifters, is a magneto-optical material placed in an external magnetic field. This traditional approach involves the use of bulky magnets creating a relatively strong and nonuniform magnetic field inside and outside the magneto-optical component. Here we achieve the same nonreciprocal functionalities by using magneto-optical composite material with zero net magnetization and not requiring a bias magnetic field.
Interaction of acoustic waves and shelled microbubbles/droplets for sensing application
Authors: Prudhomme Marc
Published: January 2023

In the field of microfluidic, microbubbles and microdroplets are studied for many applications. For instance, microbubbles are used as Ultrasound Contrast Agent (UCA) to enhance the acoustic contrast of the human blood pool during an echography, and microdroplets are mainly used as reaction chambers, leading to the development of digital microfluidics. In this project, we propose to use the surface of microbubbles and droplets for acoustic sensing application. This presentation will be focused on simulations performed to study the interaction between the acoustic wave and the microbubbles-droplets, in order to detect the capture of analytes on their surface.
Sensing the position of a single scatterer in opaque media using Mutual Extinction & Transparency
Authors: Truong Minh Duy
Published: January 2023

Traditional scattering experiments are associated with sending a single beam on a target.The detailed structure of the target including the positions of all scatterers are encoded in the characteristics of the scattered waves. However, when a medium becomes opaque, usual single scattering (Fourier) approaches break down and only limited information is available by, e.g., diffusing wave spectroscopy. Recently, the development of multiple-beam techniques, e.g., wavefront shaping, has opened more potential in the research of opaque samples. Different from the case of a single incident wave, the interference of multiple beams gives rise to a new phenomenon called ”Mutual Extinction and Transparency” [1]. Here, we conjecture that Mutual Extinction with 2 incident beams is a promising technique to detect the movement of a dipole in a sample of multiple stable dipoles (see Fig. 1 for more details). The underlying idea is that the cross-interference information of 2 beams is more sensitive to changes of the scatterer located deep within the sample than conventional 1-beam scattering methods. For comparison, we perform exact calculations of the sensitivity of Mutual Extinction (from 2 beams) and the differential cross-section (from 1 beam) in response to the displacement of 1 dipole. Our numerical results confirm that Mutual Extinction is indeed more sensitive (see Fig. 2), thus, a better tool (than traditional 1-beam techniques) to locate a single scatterer inside a multiple scattering sample.
Active mechanical metamaterials: from wave guiding to robotics
Authors: Coulais Corentin
Published: January 2023

Controlling how waves propagate, attenuate and amplify in simple, scalable geometric structures is a daunting challenge for science and technology. In this talk, I will discuss how odd matter—in which microscopic interactions are asymmetric and non-conservative—can be used to steer mechanical waves in unprecedented ways. Combining experiments active mechanical metamaterials with wave physics and continuum and topological mechanics, I will discuss the emergence of the non-Hermitian skin effect, of non-Hermitian topological waves and of one-way solitons. I will further show how these odd waves can be used to induce locomotion and unusual responses to impacts and hence pave the way towards a novel generation of robots.
Fully scattering characterization based on Mutual Extinction and Transparency
Authors: Rates Alfredo
Published: January 2023

Wavefront shaping is a revolutionary technique which proved that controlling the incident wavefront into a random media we can optimized the intensity in a point on the back, the front or even inside the random media. Recently, we discovered the Mutual Extinction effect, which shows that the crossing interference between coherent incident light and scattered light from different incident light beams modifies the total extinction of the system. Here, we present how to use this effect as a further step of wavefront shaping, controlling the extinction rather the intensity of the light.
Creating Synthetic Spaces for Higher-order Topological Sound Transport
Authors: Huang Guoliang
Published: January 2023

Modern technological advances allow for the study of systems with additional synthetic dimensions. Higher-order topological insulators in topological states of matters have been pursued in lower physical dimensions by exploiting synthetic dimensions with phase transitions. While synthetic dimensions can be rendered in the photonics and cold atomic gases, little to no work has been succeeded in acoustics because acoustic wave-guides cannot be weakly coupled in a continuous fashion. Here, we formulate the theoretical principles and manufacture acoustic crystals composed of arrays of acoustic cavities strongly coupled through modulated channels to evidence one-dimensional (1D) and two-dimensional (2D) dynamic topological pumpings. In particular,the higher-order topological edge-bulk-edge and corner-bulk-corner transport are physically illustrated in finite-sized acoustic structures. We delineate the generated 2D and four-dimensional (4D) quantum Hall effects by calculating first and second Chern numbers and physically demonstrate robustness against the geometrical imperfections. Synthetic dimensions could provide a powerful way for acoustic topological wave steering and open up a platform to explore any continuous orbit in higher-order topological matter in dimensions four and higher.
Spectral and Topological Engineering with Space Groups
Authors: Prodan Emil
Published: January 2023

I will first introduce a variety of metamaterials that are designed by acting with the elements of a space group on one or several master resonators of given shapes and internal structures. The result is a metamaterial with a rich resonant spectral structure carrying a large number of topological gaps. Furthermore, aperiodic perturbations enrich the metamaterials with a phason that lives on exotic manifolds such as the Klein bottle. In the second part of the talk, I will describe how to identify the topological labels of the gaps and how to generate interesting bulk-boundary and bulk-defect correspondences.

Diversity of Large and Medium Sized Mammals and Their Challenges in Abay (Blue Nile) Gorge in the Amhara Region of Ethiopia
Authors: Taye Dessalegn , Wale Melaku
Published: January 2023

The diversity and threats of medium and large‐sized mammals was studied in Abay (Blue Nile) Gorge, Amhara Region, Ethiopia using direct and indirect survey techniques on transect lines crossing natural forest, riverine forest and woodlands. Footprints, camera traps and group discussions were used. Data were analyzed using detrended correspondence analysis, cluster analysis, non-metric multidimensional scaling, and diversity indices. A total of 25 medium and large mammal species belonging to 6 orders and 12 families were recorded. Order Carnivora was the most abundant followed by Artiodactyla, whereas Tubulidentata, Lagomorpha and Procaviida were rare. Leopard is threatened species.  The plotting of the detrended correspondence analysis between mammal species and districts showed 61% on axis 1 and 22% on axis 2 and Gozamin district stood at the left side of the plot and Andabet, Enebise Sar Midir and Borena at the extreme right, contributing to the observed association. The mammal species were found lined up along axis 1, where Lycaon pictus and Reducna redunca were closely associated to Gozamin. The cluster analysis based on the Bray-Curtis single linkage similarity index showed differences and similarities between the mammals species composition recorded in the six districts. P. anubis, C. pygerythrus, S. grimmia, O. oreotragus, G. genetta, P. pardus pardus, H. hyaena, G. sanguinea, H. brucei, P. capensis, H. cristata stood out clearly separated from the rest of them and showed linkage at almost 50% similarity. The highest similarity (at about 96% similarity) was a cluster of four species, i.e., T. sylvaticus, T.strepsiceros, S.  scrofa and K. ellipsiprymnus. Non-metric multidimensional scaling also gave clusters of similar districts but not mammal species. Species diversity (H′) ranged from low (1.1) to average (1.9). Anthropogenic impacts were associated with decline in abundance of species and populations. Conservation schemes (nature reserves) need to be launched as soon as possible.

Published: January 2023

The objective of the present study was assessing the species composition, relative abundance and species diversity of avifauna found in wetlands of Semin Mecha District. The diversity, relative abundance and distribution of the avian species were investigated from January 2019 to August 2019 both wet and dry seasons. Both point count and line transect methods were employed to identify birds from the three wetlands. A total of 39 species, 28 genera 14 families and 8 orders were identified. The order Charadriiformes dominated the list (4 families with 14 species) followed by Pelecaniformes (2 families with 9 species), Gruiformes (2 families with 4 species), suliformes 2 families with 3 species), psseriformes (1 family with 6 species), the rest Accipitriformes, phoenicopteriformes and podicipediformes(1 family with 1 species) each. Out of total 39 species, one species (Black billed gull) was endangered, two species (wattled crane and Black crowned crane were vulnerable, one specie (Rouget's rail) was near threatened, and thirty five bird species recorded were under the Least Concern category. Species abundance and diversity varied between the three habitats. Weinner Simpson index showed significant diversity of birds in Koga reservoir had higher species diversity (H’=5.9) followed by kurt Bahir dembar(H’=4.15) and lower species diversity Kurt Bahir (H’=2.53).The study shows that habitat destruction due to anthropogenic activities:- over-grazing, sedimentation, poor management of catchment, recession farming, over-utilization of resources, lack of awareness , Lack of sense of ownership, giving less attention to conservation were the main threats to the survival of wetland birds in the study area. The current management of wetlands is poor because of misuse of wetlands as the result birds are endangered. Thus urgent conservation measures are recommended to conserve the bird species.

Mental health problems are a significant cause of disability in children and adolescents. The most common are anxiety, depression, eating disorders and somatic symptom disorder. All these disorders have a negative impact on the child/adolescent functioning and they may lead to more severe psychiatric illnesses. For these reasons, paediatricians should be able to identify the patients with high risk of psychological dysfunction, by knowing the right questions to ask and using some simple psychological assessment tools (Paediatric symptom checklist, Strengths and Difficulties Questionnaire, HEADS-ED) that can help patients to receive the psychological/neuropsychiatric support they need as soon as possible.

The current research makes an effort to identify the post effect of Covid-19 on the aviation industry in Belgium, Albania, Austria, Finland, Germany, Italy, Spain, France, Turkey and United Kingdom. The study explained the magnitude or impact of Covid cases and Covid deaths on Airline traffic, Freight traffic and Passenger traffic. To meet the objectives of the current study the two models have been tested separately. In the first model, we tested the impact of Covid cases on the study variables Airline Traffic, Freight Traffic and Passenger Traffic. In second model, we tested the impact of Covid deaths on the study variables Airline Traffic, Freight Traffic and Passenger Traffic. The study also applied the Augmented Dicker’s fully test to measure the stationarity of data. Results of the panel data showed that Covid cases as well as Covid deaths posed a significant declining impact on Air traffic, Freight traffic and Passenger traffic. Furthermore, VAR, Impulse Response Function (IRF) and Variance Decomposition has been applied for describing shocks, quantifying shocks and explaining intra and inter dependencies between the study variables in detail.

A reclamação processual é instituto do processo civil pelo qual as cortes de justiça podem fazer valer a autoridade de suas decisões. Nasceu o instituto de reiteradas decisões jurisprudenciais, e acabou inserido na legislação e nos regimentos dos tribunais. A Constituição da República e suas emendas promoveram um retraçado das linhas gerais, da utilidade e da natureza jurídica da reclamação, agora como reclamação de natureza constitucional. Os tribunais ganham autonomia para fazer valer a jurisprudência vinculante e para autoafirmar a função nomofilácica das cortes brasileiras. O método utilizado neste estudo foi a pesquisa bibliográfica histórico-comparativa sobre os momentos constitucionais e processuais de evolução do tema em doutrina e jurisprudência. Assim, o presente artigo promove a releitura da reclamação processual à luz das inovações constitucionais e legais, pelas quais se reorganizou o tema depois do Código de Processo Civil de 2015.

Published: January 2023

Background: Acceptance of day surgery has been steadily rising for over a decade. Day surgery is essential in developing countries since it allows for quick healing and lower overall costs. Day surgeries have been on the rise in recent years. Induction agents like propofol and thiopentone are frequently utilized during outpatient procedures. This study aimed to compare Hayatabad Medical Complex Peshawar grade I and II patients undergoing day surgery, the compass reading time, hemodynamic comeback, respiratory upshots, and the postoperative resurgence of the two medications. Objective: Oral midazolam, thiopental sodium, and propofol were all used for induction before day surgery. The goal was to determine which method was most cost-effective and resulted in the quickest recovery. Place and Duration: Hayatabad Medical Complex, Peshawar for the duration from January 2022 to June 2022. Methodology: A total of sixty patients were selected, practically thirty from one Hayatabad Medical Complex Peshawar. In group A, patients were given 2.0 mg/kg of propofol for compass reading, while in group B, patients were given 0.250 mg/kg of oral midazolam 30 minutes prior they were prearranged 2.50 mg/kg of thiopental sodium for induction. During the operation, doctors kept tabs on the patient's vital signs, BP, recuperation score, and ability to return home. For both groups, we calculated the typical price of induction. Result: After 30 minutes of reverse, group A scored 8.8± 1.75, and group B scored 8.01± 1.03. Group B costs (BDT 37.88±1.37) were considerably lower than (BDT 142.00±6.00), with a P value of< 0.05. Conclusion: For outpatient surgeries, using vocal midazolam and low- a prescribed amount of thiopental sodium orientation is more cost- effectual than propofol induction.

Objective: To evaluate the Risk of Malignancy Index (RMI)for primary evaluation of ovarian masses. Materials and Methods: This was a prospective observational study conducted for period of two years at DHQ hospital Jhang. Study consisted of 141 female patients admitted for surgical exploration of ovarian masses. Pre-operative ultrasound evaluation of ovarian mass, menopausal status and CA125 were carried out for the patients. Based upon these finding RMI was calculated for all the patients. Post-operative histopathology of resected ovarian mass was done in all the cases to confirm the diagnosis. Results: sensitivity and specificity of CA125 alone at cut off value of 35 was 67.64 %, 83.17% respectively. Using RMI at cut off value of 200 sensitivity and specificity was 76.47%, 85.98 % respectively. Receiver operating characteristic curve (ROC)revealed that RMI was a better discriminate than CA125, ultrasound and menopausal status alone. Conclusion: Risk of malignancy index (RMI) is useful tool in primary evaluation of ovarian masses. It can be used to differentiate between benign and malignant ovarian masses with high sensitivity and specificity.

This paper is a continuation of the previous paper and presents the fourth part of the authors’ work. In the work, nonlinear autonomous second-order differential equations with random right-hand sides of the type of white noise are considered. In the first four parts of the work, we present some mathematical preliminaries from probability theory, stochastic processes, theory of stochastic differential equations and stability theory of stochastic equations. In the fourth part, we give the basic definitions of stochastic stability, the notion of Lyapunov’s functions for the systems of stochastic differential equations, and basic theorems from the stability theory of stochastic differential equations are formulated. In the work, new sufficient conditions for stochastic asymptotic stability of solutions of the nonlinear second-order Ito’s stochastic differential equations are obtained. The probabilistic estimations of the remaining of a random trajectory in a bounded region of the phase plane are given. As an example, harmonic oscillator perturbed by white noise random process is considered

¿Una canción para siempre? La evolución de la promoción musical del pop, desde el piano del entrepiso hasta las recomendaciones de Spotify
Authors: Martínez-Gamboa Ricardo
Published: January 2023

Este artículo aborda el desarrollo de la promoción de la música pop a lo largo de los siglos XX y XXI, con especial atención y detalle en la irrupción de las recomendaciones mediante algoritmos que se ha dado en esta tercera década del tercer milenio, problematizando el impacto de los mismos en lo que se refiere al consumo musical en el contexto del modelo de Burnett (1996) y de la “sociedad de la modularidad” propuesta por Shore (1996). Nuestro objetivo es llegar a una reflexión sobre los efectos de dicho estado de cosas en la formación de identidades a partir de la audición y el fanatismo musical, la conformación de comunidades y generaciones nucleadas en torno a hits y tendencias populares, y la atomización de las audiencias.
