Data-driven Radar Processing Using a Parametric Convolutional Neural Network for Human Activity Classification
Authors: Stadelmayer Thomas , Santra Avik
Published: March 2021

Radar sensors offer a promising and effective sensing modality for human activity classification. Human activity classification enables several smart homes applications for energy saving, human-machine interface for gesture controlled appliances and elderly fall-motion recognition. Present radar-based activity recognition system exploit micro-Doppler signature by generating Doppler spectrograms or video of range-Doppler images (RDIs), followed by deep neural network or machine learning for classification. Although, deep convolutional neural networks (DCNN) have been shown to implicitly learn features from raw sensor data in other fields, such as camera and speech, yet for the case of radar DCNN preprocessing followed by feature image generation, such as video of RDI or Doppler spectrogram, is required to develop a scalable and robust classification or regression application. In this paper, we propose a parametric convolutional neural network that mimics the radar preprocessing across fast-time and slow-time radar data through 2D sinc filter or 2D wavelet filter kernels to extract features for classification of various human activities. It is demonstrated that our proposed solution shows improved results compared to equivalent state-of-art DCNN solutions that rely on Doppler spectrogram or video of RDIs as feature images.
A partire da «Underworld»
Authors: Turi Nicola
Published: March 2021

The volume is a commentary on Don DeLillo’s hypertrophic novel Underworld (1997). Starting from the analysis of the text – which intertwines several plots, locations and point of view –, Nicola Turi retraces the entire production of the author to follow the evolution of themes (paranoia, nuclear threat, alienation, violence…) and textual strategies. At the same times he considers some widespread trends in the contemporary novel which Underworld, narrative tableau of the United States of the second twentieth century, embodies or anticipates: the resumption of the collective novel; the construction of characters drawn from reality; the continuous interaction between verbal representation and image (both static and moving).

مسارات الإبلاغ الحِجَاجيّ في الخطاب الشّعريّ لأبي طالب(عليه السلام) (اللاميّة) مثالاً
Authors: عبدالله الدكتورة الاء علي
Published: March 2021

الشراكة في المعارف البانية، سمة عصرية أضحت محمودة بعد التطور الأنساقي السريع الذي عكس المرونة الواسعة للتشكيلات المعرفية. ونحن إذ نقف على نصّ شعريّ تراثيّ، ونأخذ نظرية مهمة ذات ثقل حداثي لنلامس بها النصّ ونناقشه، فإننا بذلك نقوم بعملية الشراكة المذكورة تلك.

      تأخذ هذه الدراسة بنص لامية أبي طالب عليه السلام عمّ النبي صلى الله عليه وآله وسلم  لتعرضه على المنهج الحجاجي فيتعاطى معه بآلياته المتمثلة بالسلّم الحجاجي، والروابط الحجاجية والعوامل الحجاجية ، ليستخرج ما تكدّس في خطابه من شحنات حجاجية حاول الشاعر توجيهها صوب المتقبِّل المتلقي ليعدّل في وجهته أو يغيرها ، من خلال التأثير في قناعاته ومفاهيمه .

     فجاءت هذه الدراسة الموسومة بــ" مسارات الابلاغ الحجاجي في الخطاب الشعري لأبي طالب  عليه السلام   " اللامية (مثالاً) مقسّمة على مقدمة ومفصلين ؛ نظري، وإجرائي، وخاتمة ومظان البحث. لتقرّب بين: نصّ تراثيّ ونظرية حداثيّة من جهة، والخطاب الشعريّ والنظرية الحجاجية من جهة أخرى. والله تعالى ولي التوفيق .

علي جعفر العلاّق وجهوده في تحديث الخطاب النقدي في العراق (في حداثة النّص الشعري) أنموذجًا
Authors: علي محمد دكتور خليل شيرزاد
Published: March 2021

يتعرّض  المنجز النقدي شأنه في ذلك شأن المنجز الشعري والأدبي لرياح الحداثة، فيحاول جاهداً أن يتمثّل هذه الحداثة في جوهرها لتضيفَ  حلقة جديدة في سُلّم  رقيّها وصولاً إلى النضج أو مقاربته على أقلّ تقدير.

ولأنّ مفهوم الحداثة لم يعد مقتصراً في الساحة الثقافية على ميدان دون سواه، بل شمل كلّ أنساق الثقافة فضلاً عن العلوم الانسانية والطبيعية ، فليس بمستغرب أن  يتفيّأ النقد العربي الحديث ظلال الحداثة بقصد الإفادة والإضافة العلمية الرصينة، ولا سيّما بعد التّحول الجذري  في طبيعة الخطاب النقدي العراقي ، والعربي من طور الإبداع إلى طور الاتباع.

  تهدف هذه المداخلة المتواضعة إلى مقاربة مشروع ومنجز (علي جعفر العلاّق) النقدي ، ومحاولة ابراز قَسَمَات مَتْنهِ النقدي جهد الإمكان، وفي الوقت ذاته هي محاولة جادّة للتعريف بالمنجز النقدي العراقي الحديث من خلال (العلاّق) نموذجاً، وبيان مدى افادته من معطيات العصر الحداثوية ومدى تمثّله لها.

Published: March 2021

Chemical flooding is one of the major enhanced oil recovery (EOR) techniques particularly for reservoirs where thermal methods are not applicable, that chemical flooding may be polymer flooding, alkaline flooding, surfactant flooding, or a combination of them. The application of designing a chemical flooding program is strongly affected by the current economics, reservoir oil type, and crude oil price. In this project, mechanisms of different chemical methods will be discussed, and design chemical flooding program by using a laboratory scale and programming method. This project is mainly about making a design of surfactant flooding program, through choosing the optimum surfactant concentration. Also, economic study is very important in designing the program to know if the project is profitable or not to identify its efficiency, and choosing the better type of surfactant flooding in the reservoir. The results of this project proved that the surfactant has good effect on rock wettability to more water- wet, so increase the hydrocarbon recovery.

IMPACT OF LOGISTIC INFRASTRUCTURE SELECTED ELEMENTS ON THE EFFICIENCY OF AIR TRANSPORT
Authors: ORŁOWSKI Łukasz , MODRZEWSKA Magdalena
Published: March 2021

Przewozy lotnicze są najbardziej dynamicznie rozwijającą się gałęzią transportu. Z uwagi jednak na wysokie koszty środków transportu, infrastruktury oraz paliwa, skomplikowane procedury obsługi i bezpieczeństwa są jednocześnie jedną z najdroższych. Dążeniem przewoźników jest podjęcie działań mających na celu minimalizacje kosztów własnych i maksymalizację zysków. W transporcie lotniczym działania te sprowadzają się do zmian w zakresie infrastruktury transportu, czyli wprowadzania nowoczesnych, zużywających mniej paliwa i zabierających na pokład więcej pasażerów lub towaru samolotów oraz uproszczenie i skrócenie procedur obsługi w reżimie czasu.

The purpose of the research to determine the legality aspects of street vendors in the Malioboro tourist area and to analyze the applicable legal sanctions for violators of the rules for good area governance. Street vendors carry out their business to support the economy in fulfilling their daily needs, but there is a need for the realization of an arrangement of regional spatial functions that takes into account all aspects optimally. The Yogyakarta City Government has made a policy in terms of structuring street vendors in order to create a good spatial plan in the Malioboro area. The data collection method in this research is juridical normative by examining secondary data. The results of the study concluded that the street vendors in the Malioboro area can be recognized if they already have a Location Use Permit and have an Identity Card based on the location and provisions on the type of goods. The prohibition for street vendors trading in the Malioboro area is regulated in a Yogyakarta Mayor Regulation and a Yogyakarta City Regional Regulation. Violators of the rules can be subject to criminal sanctions and administrative sanctions as stated in the regulation.
STRATEGI SISWA “EXTROVERT” DALAM MEMPELAJARI KETERAMPILAN BERBICARA BAHASA INGGRIS
Authors: Arif Ummi Qalsum
Published: March 2021

Berbicara adalah salah satu keterampilan yang paling diprioritaskan untuk dikuasai oleh siswa karena mereka akan lebih mudah memahami materi dan mereka akan lebih mudah untuk menanyakan sesuatu dalam bahasa Inggris ketika merasa bingung. Faktanya, para guru dan siswa perlu lebih berhati-hati dalam beberapa faktor internal yang mungkin mempengaruhi siswa dalam menguasai bahasa Inggris. Keberhasilan pembelajaran berbicara tidak selalu bergantung pada strategi yang diterapkan oleh guru di kelas, Namun keberhasilannya juga berpengaruh besar dari strategi yang digunakan siswa dalam pembelajaran berbicara. Salah satu faktor internal yang dapat mengganggu penguasaan berbicara siswa adalah kepribadian. Ekstrovert memiliki pengaruh terbesar dalam pembelajaran bahasa terutama dalam meningkatkan keterampilan berbicara. Tujuan dari penelitian ini adalah untuk mengetahui strategi yang digunakan oleh siswa ekstrovert dalam pembelajaran keterampilan berbicara. Desain penelitian yang digunakan dalam penelitian ini adalah penelitian kualitatif deskriptif. Subjek penelitian ini adalah lima siswa ekstrovert di International Class Program (ICP) kelas XI SMA Laboratorium UM. Alat tes kepribadian, catatan observasi lapangan, dan wawancara tidak terstruktur digunakan untuk mengumpulkan dan menganalisis data. Hasil penelitian menunjukkan bahwa sebagian besar siswa ekstrovert menggunakan strategi Kognitif, Meta kognitif dan Sosial dalam mempelajari kemampuan berbicara. Selain itu, dalam strategi kognitif dan sosial, siswa ekstrovert selalu berbicara bahasa Inggris dengan orang yang mereka temui dan mereka merasa nyaman untuk berbicara bahasa Inggris dengan banyak orang di sekitar mereka.

Institutional Issues
Authors: Benenson Jodi
Published: March 2021

The process of institutionalizing service-learning and community engagement and the effects of these approaches on educational organizations has long been a topic in the field’s literature. Previous research has demonstrated a need to understand the ways in which institutions engage with issues affecting all aspects of service-learning and community engagement, including interactions with faculty, students, community partners, and institutional and organizational leadership and decision-making. Trends in the field of service-learning and community engagement also call on practitioners to focus on the social, political, economic, and cultural factors that underlie institutional processes.
Value Added: Service-Learning Outcomes for Physical Therapy Students and Community Partners in Belize
Authors: Beitman Candace , Gahimer Julie , Staples William
Published: March 2021

This study comprised a follow up to a two-week interdisciplinary service-learning (SL) trip to Belize for graduate students from a private Midwestern university. Trip participants engaged in SL activities with multiple partnering agencies in various locations. The purpose of the study, which employed a qualitative, constructivist, focus-group design, was to explore the perceptions of students and community partners about the services provided. Data were analyzed for common themes using line-by-line and constant comparative methods. Six themes emerged from the data. Community partners complimented the education and training provided, and requested additional time and programming for future visits. Some identified the need for increased collaboration and additional preparation of students prior to the visit. Students demonstrated increased appreciation for interdisciplinary practice, enhanced professionalism, and greater sensitivity to cultural differences, and expressed their desire to participate in future international service trips. These findings supported the conclusion that interdisciplinary international SL activities are mutually beneficial to students and community partners.
Students’ Emotional Experiences in Direct Versus Indirect Academic Service-Learning Courses
Authors: Darby Alexa , Perry Sara , Dinnie Maureen
Published: March 2021

Research in psychology has emphasized the important role emotions play in learning (Pekrun, 1992). The purpose of the study highlighted in this article was to compare the emotional experiences of college students enrolled in direct academic service-learning (AS-L) courses with those of students enrolled in indirect AS-L courses. Eighteen college students participated in individual interviews, discussing positive and negative emotions resulting from their AS-L experiences. Students who engaged in direct AS-L reported significant emotional responses to interactions with people at their AS-L site. Students who engaged in indirect AS-L courses emphasized their emotional responses to working with peers and community partners. Participants in direct service-learning classes made very few references to the emotional aspects of discussions, assignments, or other activities that occurred in class, while college students in indirect service-learning classes more frequently reported emotional responses to the

coursework.

Ārzemju ceļojumu iespaidi latviešu rakstnieku darbos t. s. „Brežņeva laikmetā”: liecības par atļauto un liegto
Authors: Oga Jānis
Published: March 2021

This paper examines travels outside the Soviet Union by Latvian writers who were recognised by the occupation regime and acclaimed by the public during the Brezhnev era –from the 1960s into the 1980s – as one of the privileges enjoyed by the so-called creative intelligentsia, and how those travels were reflected in their literary and journalistic writings.
The writers studied were born between 1910 and 1939 and can be seen as belonging to three different generations. The generational differences have a significant impact on how their experiences were treated in their works. Some of the texts considered in this paper are manifestations of their authors’ authentic creativity, whilst others exhibit obeisance to the status quo of their time and obligatory praise for the regime. But can a line between the two be clearly drawn? What were the goals and possibilities for travel among recognized and materially secure writers? What were they permitted to tell those readers who had no such travel opportunities? How did the notes they published in periodicals differ from the versions that later appeared in books?
The methodological basis for this paper is the work of Alexei Yurchak, a Russian-born American anthropologist who provides a unique understanding of the concept of ‘the abroad’ (заграница) in the Soviet Union as demarcating not actual borders or territory but an imagined space, and the insights of the Canadian historian Anne E. Gorsuch about Soviet tourism abroad. Gorsuch has studied how Soviet citizens internalised Soviet norms and supported Soviet goals, but also the attempts by tourists to evade official constraints on their experience in foreign lands and how they sought to devise their own individual itineraries. Journeys abroad elicited conflicting emotions. Writers had to be comparatively affluent to travel, but they often experienced humiliation when confronted with the reality of their meager financial means outside the U.S.S.R. and the fact that they remained in durance even in the free world. Versions of their writings published in the post-Soviet period and later commentaries bear witness to episodes that could not be described in the Brezhnev era as well as self-censorship.
Divi pirmās personas stāstījumi Osvalda Zebra romānā „Māra”
Authors: Zirnīte Daiga
Published: March 2021

The aim of the study is to define how and to what effect the first-person narrative form is used in Oswald Zebris’s novel “Māra” (2019) and how the other elements of the narrative support it. The analysis of the novel employs both semiotic and narratological ideas, paying in-depth attention to those elements of the novel’s structure that can help the reader understand the growth path and power of the heroine Māra, a 16-year-old young woman entangled in external and internal conflict. As the novel is predominantly written from the title character’s point of view, as she is the first-person narrator in 12 of the 16 chapters of the novel, the article reveals the principle of chapter arrangement, the meaning of the second first-person narrator (in four novel chapters) and the main points of the dramatic structure of the story.
Although in interviews after the publication of the novel, the author Zebris has emphasised that he has written the novel about a brave girl who at her 16 years is ready to make the decisions necessary for her personal growth, her open, candid, and emotionally narrated narrative creates inner resistance in readers, especially the heroine’s peers, and therefore makes it difficult to observe and appreciate her courage and the positive metamorphosis in the dense narrative of the heroine’s feelings, impressions, memories, imaginary scenes, various impulses and comments on the action. It can be explained by the form of narration that requires the reader to identify with the narrator; however, it is cumbersome if the narrator’s motives, details, and emotions, expressed openly and honestly, are unacceptable, incomprehensible, or somehow exaggerated.
Using perceptual tasks to selectively measure magnocellular and parvocellular performance: Rationale and a user’s guide
Authors: Edwards Mark , Goodhew Stephanie C. , Badcock David R.
Published: March 2021

The visual system uses parallel pathways to process information. However, an ongoing debate centers on the extent to which the pathways from the retina, via the Lateral Geniculate nucleus to the visual cortex, process distinct aspects of the visual scene and, if they do, can stimuli in the laboratory be used to selectively drive them. These questions are important for a number of reasons, including that some pathologies are thought to be associated with impaired functioning of one of these pathways and certain cognitive functions have been preferentially linked to specific pathways. Here we examine the two main pathways that have been the focus of this debate: the magnocellular and parvocellular pathways. Specifically, we review the results of electrophysiological and lesion studies that have investigated their properties and conclude that while there is substantial overlap in the type of information that they process, it is possible to identify aspects of visual information that are predominantly processed by either the magnocellular or parvocellular pathway. We then discuss the types of visual stimuli that can be used to preferentially drive these pathways.
Pre-Internationalization and Performance Conditions of First-Time Exporting SMEs
Authors: Meschi Pierre-Xavier , Ricard Antonin , Tapia Moore Ernesto
Published: March 2021

This article aims to determine whether pre-internationalization conditions improve the performance of first-time exporting small and medium-sized enterprises (SMEs). Two pre-internationalization conditions are discussed here: firm performance and age at internationalization. Building on the aspiration-level performance model of March and Shapira (1992) with sequential internationalization and international new-ventures approaches, this article develops two research hypotheses proposing an effective alignment with pre-internationalization performance and age at internationalization. These research hypotheses are examined using a panel database of 522 French SMEs that began export operations for the first time in 2014. The statistical results partially support our first hypothesis by showing that early-internationalizing SMEs with a lower performance relative to their peers significantly increase their post-internationalization performance. Contrary to what we predicted in our second hypothesis, we observe that late-internationalizing SMEs, which deliver a much higher performance than their historical aspirations, significantly reduce their post-internationalization performance.

Published: March 2021

A aprendizagem em Genética é um processo que deve ser realizado com base no uso de estratégias que contribuam para a aquisição efetiva do conhecimento. Nesse contexto, a atuação dos professores faz-se um fator essencial para que metodologias diferenciadas sejam incorporadas no processo de ensino, o que deve ocorrer com a participação dos alunos, os quais contribuirão para identificar sua viabilidade e aplicação. O objetivo deste trabalho foi identificar a percepção apresentada pelos alunos quanto ao processo de aprendizagem em Genética no ensino médio e superior. Para isto, foi realizada um pesquisa descritiva com 40 alunos do curso de Licenciatura em Ciências Biológicas da Faculdade de Educação, Ciências e Letras de Iguatu/Universidade Estadual do Ceará. Metade do público foram alunos do 1° semestre, os quais haviam concluído o ensino médio recentemente, fornecendo informações relativas a este nível de ensino. Os demais foram alunos do 5° semestre, os quais haviam cursado Genética no 4° semestre e apresentaram informações relativas à sua aprendizagem no ensino superior. Os dados foram coletados mediante a aplicação de um questionário, sendo posteriormente transformados em porcentagens e apresentados na forma de gráficos. Pelos resultados obtidos conclui-se que o aprendizado em Genética é um processo que deve ser fortalecido por mudanças na forma de ensino, incorporando-se a esta metodologias diferenciadas e ativas, o que deve ser realizado com base na percepção dos alunos nos diferentes níveis de ensino.

Os resultados foram submetidos à análise de variância, e quando ocorreram diferenças significativas, identificadas pelo teste F (P<0,05), se aplicou o teste de médias de Tukey, utilizando-se programa estatístico Sisvar, versão 5.6. O milho FS 2B610 PW respondeu positivamente à adubação nitrogenada de cobertura, em todas as características estudadas. Nas condições de solo e clima da área analisada, a adubação de cobertura nitrogenada para o desenvolvimento do milho é mais eficiente quanto a aplicação do N em cobertura é realizada no estádio vegetativo V4, se assemelhando produtivamente à dose parcelada em V4 e V8. A realização da adubação nitrogenada total de forma tardia, em V8, não gera efeito positivo no desenvolvimento da planta e na produtividade.

Published: March 2021

Background: Pectin, a naturally occurring polysaccharide is more than a food additive and has got amazing properties as a gelling agent and as a binder.

Objective: The current research entails the extraction and identification of pectin from peels of selected fruits mango (Magnifera indica) and banana (Musa paradisiaca) by direct heating and using alcohol as precipitating agent. The potential of pectin as a binding agent in tablet formulation was evaluated by screening its micromeritics and post compression properties.

Method: quadruple formulations of ibuprofen with crude peel pectin extracted from mango and banana in concentration of 50, 75, 100 and 125 mg respectively were employed in the tablet manufacture process by wet granulation method.

Results: Successful formulation of tablet was done with the extracted pectin from the two fruit peels. The micromeritics properties showed good binding and flowing properties. An increase in concentration of pectin increased the hardness and also the dissolution of tablets up to a certain extent. The disintegration time was suitable for all formulations.

Conclusion: It was concluded that pectin extracted from mango and banana peels can be used as a super disintegrating agent in pharmaceutical formulations, where needed.

Background: The infection (COVID-19) inflicted via newly discovered strain of the virus was first spotted in Wuhan in December 2019 and established as a worldwide public health emergency on 30th January, 2020 demanding support from all healthcare sectors, on urgent basis.

Objective: The objective of this review is to highlight and appreciate roles of community pharmacists during COVID-19 pandemic.

Methodology: For literature review various databases were used such as Google Scholar, Springer Link, PubMed, MEDLINE and Science Direct.

Results: The proposed provisions such as social distancing and lockdowns to quite an extent aided in restricting the dispersion of the virus. In addition, wearing face mask, washing hands, using sanitizer with periodic disinfection of surrounding was recommended. These measures were registered to provide protection to all and positively influence the life of special population i.e., those suffering from chronic diseases, as they don't approach the healthcare facilities on a regular basis for their everyday care and supervision, in terms of medication. However, the easiest approach to gain access to sophisticated health facilities in such conditions remained and is through retail pharmacy outlets.

Conclusion: The existing healthcare system with surging stress and fear can be profoundly reduced by participation of community pharmacists and their thorough involvement in managing chronic illnesses and strengthening medication adherence.

We analyze five epochs of Neutron star Interior Composition Explorer (NICER) data of the black hole X-ray binary MAXI J1820+070 during the bright hard-to-soft state transition in its 2018 outburst with both reflection spectroscopy and Fourier-resolved timing analysis. We confirm the previous discovery of reverberation lags in the hard state, and find that the frequency range where the (soft) reverberation lag dominates decreases with the reverberation lag amplitude increasing during the transition, suggesting an increasing X-ray emitting region, possibly due to an expanding corona. By jointly fitting the lag-energy spectra in a number of broad frequency ranges with the reverberation model reltrans, we find the increase in reverberation lag is best described by an increase in the X-ray coronal height. This result, along with the finding that the corona contracts in the hard state, suggests a close relationship between spatial extent of the X-ray corona and the radio jet. We find the corona expansion (as probed by reverberation) precedes a radio flare by ∼5 days, which may suggest that the hard-to-soft transition is marked by the corona expanding vertically and launching a jet knot that propagates along the jet stream at relativistic velocities.

MeliponaIlliger, 1806 is represented by 74 known species of stingless bees, distributed throughout the Neotropical region. Cytogenetically it is the most studied stingless bee genus of the tribe Meliponini. Member species are divided in two groups based on the volume of heterochromatin. This study aim was to analyze the composition and organization of chromatin of the stingless bee subspeciesMelipona seminigra merrillaeCockerell, 1919 using classical and molecular cytogenetic techniques, so contributing to a better understanding of the processes of chromosomal changes within the genus. We confirm thatM. seminigra merrillaehas a chromosome number of 2n = 22 and n = 11, results that differ from those reported for the genus in the absence of B chromosomes. The heterochromatic pattern revealed a karyotype composed of chromosomes with a high heterochromatin content, which makes it difficult to visualize the centromere. Silver nitrate impregnation (Ag-NOR) showed transcriptionally active sites on the second chromosomal pair. Staining of base-specific fluorophores DAPI-CMA3indicated a homogeneous distribution of intensely DAPI-stained heterochromatin, while CMA3markings appeared on those terminal portions of the chromosomes corresponding to euchromatin. Similar to Ag-NOR, fluorescence in situ hybridization (FISH) with 18S ribosomal DNA probe revealed distinct signals on the second pair of chromosomes. Microsatellite mapping (GA)15showed markings distributed in euchromatic regions, while mapping with (CA)15showed marking patterns in heterochromatic regions, together with a fully marked chromosome pair. Microsatellite hybridization, both in heterochromatic and euchromatic regions, may be related to the activity of transposable elements. These are capable of forming new microsatellites that can be dispersed and amplified in different regions of the genome, demonstrating that repetitive sequences can evolve rapidly, thus resulting in within-genus diversification.

A new species of the genus Cnemaspis Strauch, 1887 is described from the Rajgad fort in the northern Western Ghats of Maharashtra, India. The new species, belonging to the flaviventralis clade, is one of the smallest known Indian Cnemaspis and can be distinguished from other congeners by its genetic distinctiveness and few key morphological characters. The new species can be diagnosed from all other Indian congeners by its small body size (SVL < 27 mm), the absence of conical and spine-like tubercles on flank; heterogeneous dorsal pholidosis; presence of only femoral pores and no precloacal pores in males; weakly keeled scales on the ventral surface of neck, pectoral, abdominal region and limbs; granular scales on the tail with whorls of slightly enlarged, strongly keeled tubercles; and the absence of enlarged median subcaudal scales. The new species is currently known to inhabit the man-made historical structures from a single locality in Rajgad, Maharashtra, where it is presumed to be uncommon.

Authors: Almeida Rafael F. , Pellegrini Marco O. O.
Published: March 2021

A new species of Heteropterys belonging to the Parabanisteria informal group is described for the savannas grasslands of the Serra do Tombador Natural Reserve, municipality of Cavalcante, State of Goiás, Brazil. Heteropterys rosmarinifolia is easily distinguished from the remaining Brazilian species of the Parabanisteria informal group due to its stems unbranched, leaves associated with the inflorescence verticillate, blades linear to very narrowly oblong, strongly conduplicate, ascending to upright, and sparsely sericeous to glabrous at age. We present a complete morphological description for the new species, photographic plates, comments on its distribution, ecology, and taxonomy, besides an identification key to the species of Heteropterys from the Parabanisteria group from the State of Goiás, Brazil.
Stable recovery of a non-compactly supported coefficient of a Schrödinger equation on an infinite waveguide
Authors: Soussi Yosra
Published: March 2021

We study the stability issue for the inverse problem of determining a coefficient appearing in a Schrödinger equation defined on an infinite cylindrical waveguide. More precisely, we prove the stable recovery of some general class of non-compactly and non periodic coefficients appearing in an unbounded cylindrical domain. We consider both results of stability from full and partial boundary measurements associated with the so called Dirichlet-to-Neumann map.
Convergence rates of Tikhonov regularization for recovering growth rates in a Lotka-Volterra competition model with diffusion
Authors: Chen De-han , jiang Daijun
Published: March 2021

In this paper, we shall study the convergence rates of Tikhonov regularizations for the recovery of the growth rates in a Lotka-Volterra competition model with diffusion. The ill-posed inverse problem is transformed into a nonlinear minimization system by an appropriately selected version of Tikhonov regularization. The existence of the minimizers to the minimization system is demonstrated. We shall propose a new variational source condition, which will be rigorously verified under a Hölder type stability estimate. We will also derive the reasonable convergence rates under the new variational source condition.
A note on transmission eigenvalues in electromagnetic scattering theory
Authors: Cakoni Fioralba , Meng Shixu , Xiao Jingni
Published: March 2021

This short note was motivated by our efforts to investigate whether there exists a half plane free of transmission eigenvalues for Maxwell's equations. This question is related to solvability of the time domain interior transmission problem which plays a fundamental role in the justification of linear sampling and factorization methods with time dependent data. Our original goal was to adapt semiclassical analysis techniques developed in [21,23] to prove that for some combination of electromagnetic parameters, the transmission eigenvalues lie in a strip around the real axis. Unfortunately we failed. To try to understand why, we looked at the particular example of spherically symmetric media, which provided us with some insight on why we couldn't prove the above result. Hence this paper reports our findings on the location of all transmission eigenvalues and the existence of complex transmission eigenvalues for Maxwell's equations for spherically stratified media. We hope that these results can provide reasonable conjectures for general electromagnetic media.
