A Cluster of FPAAs to Recognize Images Using Neural Networks
Authors: García Moreno Daniel , Del Barrio Alberto A , Botella Guillermo , Hasler Jennifer
Published: February 2021

Analog computing has been recovering its relevance in the recent years. FPAAs are the equivalent to FPGAs but in the analog domain. The main drawback of FPAAs is their reduced integration capacity. In order to increase the amount of analog resources, in this paper a cluster of 40 FPAAs is proposed. As a use case, a 19-8-6-4 feedforward Neural Network has been implemented on such cluster. With the help of a DCT-based software framework, this NN is able to classify 28x28 MNIST images. Results show that the analog network is able to obtain almost the same results as the software baseline network.

Published: February 2021

La presentación clínica del síndrome aórtico agudo (SAA) impone un reto diagnóstico para los médicos emergenciólogos. Su muy variable forma de presentación y pobre especificidad sintomática tornan el diagnóstico muy difícil, siendo la clave para su diagnóstico el alto índice de sospecha clínica. La disección aórtica es la forma más frecuente de síndrome aórtico agudo, seguido del hematoma intramural y la úlcera penetrante aórtica. Los defectos cardiovasculares congénitos, síndromes genéticos, y variantes genéticas no sindrómicas han sido asociadas al desarrollo de síndrome aórtico agudo. El diagnóstico del SAA puede ser realizado utilizando modalidades imagenológicas tales como la Tomografía, Ultrasonografía y Resonancia Magnética. Dependiendo del segmento aórtico comprometido, el manejo puede ser médico y/o quirúrgico. Se reportan dos casos de SAA atendidos en el Departamento de emergencia de la Clínica Delgado durante el año 2015.

Dil siyasəti anlayışı dilçilikdə hələ də tam mənası ilə müəyyənləşməmişdir. “Dil planlaşdırılması” və “dil quruculuğu” terminlərindən istifadə edən dilçilər, “dil siyasəti” termininin adətən, dilə məqsədli və düşünülmüş təsirini nəzərdə tutaraq daha uyğun olduğunu irəli sürürlər. Sosium dil sisteminə qeyri-iradi və məqsədli təsir edə bilər. Cəmiyyətin dilə məqsədli təsiri müxtəlif xarakterli ola bilər və bu dil siyasəti adlanır. Sosial amillərin öz növbəsində, hər hansı bir şəkildə təzahürü dilə qlobal və yerli təsir edə bilər. Bu barədə aparılan araşdırmalar sosial amillərin dilin daxili qanunları ilə sıx bağlı olduğunu müəyyən etmişdir. Cəmiyyətin və ya dövlətin dil sisteminə birbaşa təsirinə dair tarixdə çoxlu nümunələr vardır ki, onlardan biri də yeni dövlət yaradılarkən bu və ya digər dilin dövlət üçün rəsmi dövlət dili kimi qəbul edilməsidir. Bu fəaliyyətin dil siyasəti kimi adlandırılması irəli sürülmüşdür. Dil siyasəti tarixdən də qəbul olunduğu kimi, bir çox istiqamətlərdə aparıla bilər. “Dil siyasəti – əslində, kifayət qədər mürəkkəb struktura malik hadisədir; hər şeydən əvvəl ona görə ki, burada dilin təbii imkanları, tarixi situasiya və subyektiv maraqlar, yaxud iddialar qarşılaşır.

At the same time, the concept of the truth is being analyzed in the context of episteme and doxa and, accordingly, the hierarchical idea of knowledge, formed by the philosopher, is being investigated. The world of ideas, which forms the basis of Plato's philosophy, is assessed as a world where there is the truth and the unity, the true is separated from its shadow. In addition to the above, Plato's ways of achieving the metaphysical truth are being discussed. The article emphasizes that Plato was the first representative of the oldest theory in history, the theory of correspondence of the truth.

The heritage of Nizami Ganjavi is the spiritual wealth of the Azerbaijani people, and the protection and research of this heritage are in the spotlight as a part of the political action of Azerbaijan’s government. Unfortunately, the recent publication of the series of articles with distortions about the life and origin of the great Azerbaijani poet Nizami Ganjavi on websites, as well as the dissemination of false information, not only compromise the level and achievements of world orientalists, but also impede the development of Azerbaijani Nizami studying. Executors of Armenian interests falsify Nizami Ganjavi’s nationality, publish motiveless books and articles, consider Azerbaijani scientists as “ethnic nationalists,” and reinterpret our history and culture. However, these attempts are doomed to failure due to the absent of scientific justification. The purpose of this article is not to list the distortions, but to study the sources and causes of these aberrations. Key words: Nizami Ganjavi, wikipedia, distortion, textology, language

Published: February 2021

In the present research work, the Canadian Council of Ministers of the Environment water quality index 1.0 (CCME WQI 1.0) was applied to assess water quality of Tehri dam reservoir by using the drinking water standard prescribed by the WHO (1999) and BIS (IS:10500, 1991). The physico-chemical parameters, ions concentration and heavy metals concentration used in the index calculation were total dissolved solids, pH, alkalinity, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, total hardness, calcium, chloride, phosphate, sulphate, nitrate, total coliform (MPN/100 ml), turbidity, zinc, manganese, lead, nickel, iron and chromium. It was observed during the course of study that at all the four sites BOD, phosphate and total coliform showed greater deviation from the objective values. Total coliform was found to be more deviated from the normal values. Few important parameters were observed beyond the permissible limit for many times. The values of water quality index have shown that most of the sites are not fit for drinking purpose. Finally it was concluded that reservoir water should not be consumed for drinking purposes frequently without proper treatment.

O território brasileiro possui a segunda maior diversidade de espécies de aves do planeta. No entanto, as ações humanas têm influenciado significativamente os ambientes montanhosos que abrigam as principais aves brasileiras ameaçadas de extinção. Portanto, o objetivo deste estudo foi (i) avaliar a comunidade de aves em campos rupestres de um ecossistema montano do ecótono Mata Atlântica-Cerrado; (ii) medir as perdas de áreas de campo a partir de análises temporais de imagens de satélite; e (iii) analisar as espécies de aves ameaçadas, principalmente a variação sazonal. O estudo foi realizado em uma área localizada em um ecossistema montano situado em uma região ecotonal entre dois hotspots globais de biodiversidade, a Mata Atlântica e o Cerrado. Um total de 45 espécies e 357 indivíduos foram registrados nos campos rupestres, e as famílias mais representativas foram Thraupidae e Tyrannidae. Além disso, identificamos uma diminuição nas áreas de campo rupestre por mudanças na cobertura do solo (plantações de eucalipto) de 2000 a 2019 anos, que correspondeu a 576,27ha. Os resultados mostraram registros de três espécies ameaçadas; Anthus nattereri, Coryphaspiza melanotis e Culicivora caudacuta, que não variaram entre as estações climáticas. Ressaltamos que as aves encontradas neste estudo, principalmente as ameaçadas, requerem prioridade de conservação devido às perdas de habitat.

Published: February 2021

Nowadays no herbicide has been approved for use on chickpea crops has been officially registered in Ukraine. Weed control measures are mainly used. However, many years of experience in the use of a number of herbicides in our country and in other countries. In this regard, the effectiveness and selectivity of soil preparations such as Harnes, 90% k.e., and Frontier Optima, 72% k.e. were studied in chickpea crops. These herbicides were applied after sowing chickpeas until the emergence of seedlings. Application of Harness herbicide, 90% k.e., at a rate of 3.0 l / ha in the soil before the emergence of chickpea seedlings leads to a decrease in weed vegetation a month after application of the herbicide to 88% compared to control areas where measures to protect against storms vegetation was not carried out.
The regulation of the number of weeds and their harmful effects in chickpea agrophytocenoses to an economically harmless level is an important condition in the technology of its cultivation. The most relevant weed control is at the beginning of the growing season of the crop, since this the chickpea grows very slowly, is in the rosette phase for a long time, and therefore does not withstand competition from weeds. To increase the yield of chickpea seeds, an important place in the technology of growing crops is the use of herbicides and biological products. Inoculation of chickpea seeds with Rizobofitt at a consumption rate of 1 l / t and with a biofungicidal preparation Biopolycide at a consumption rate of 100 ml/t, by introducing a soil herbicide Frontier Optima, 72% k.e., at a consumption rate of 1,2 l/ha, contribute to the reduction of weeds to 91%, and the ability to obtain the yield of chickpea seeds at the level of 2,12 t/ha.

An extra-terrestrial impact crater is a crater that is formed by an extra-terrestrial impact event whereby a heavenly body (a meteor, comet, or asteroid) hits the earth’s surface and creates a crater; before it cools on the earth’s surface as a meteorite or completely gets squashed by the thermodynamics of space transit. The crater created can be dry or filled with water and may be a simple crater or a complex one, also denoted as a basin. The objective of this paper is to describe the geology of the Silali basin as an Extra-Terrestrial Impact Crater (ETIC), highlight the importance of some of its ETIC rocks and explain the formation of the Silali basin resulting from extra-terrestrial impact. Data was collected through field observation, remote sensing, analysis of past geographical and geological studies, interviewing and laboratory analysis. Information has been presented in the form of analyzed satellite images, pictures, tables, and maps. Notably, this is the first study on extra-terrestrial impact cratering (ETIC) in Kenya. Consequently, the Silali basin, as an ETIC, and its environs, is a virgin field for further scientific research.

We have investigated the effectiveness of higenamine in the treatment of malignant glioma, and explored its possible mechanism in C6 glioma cells. The efficacy of higenamine on viability of cells, apoptosis, cell cycle arrest, DNA fragmentation, and biochemical markers was examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, flow cytometry, enzyme-linked immunosorbent assay, and Western blotting. The biochemical markers investigated included the effect of higenamine on the expression of phosphoinositide-3-kinase/protein kinase B, B-cell lymphoma 2, BCL2- associated X protein, cysteine-aspartic proteases-3 and -9 proteins. The translocation of nuclear factor-kappa B from the nucleus was also analyzed. Results revealed that higenamine induced cytotoxic and antiproliferative effects on the C6 glioma cells. Higenamine led to cell arrest at G2/M phase of cell cycle and lowered cell count at S-phase. The maximum extent of DNA fragmentation was observed after 72 h exposure of higenamine. Nuclear translocation of nuclear factorkappa B was attenuated after higenamine treatment in the C6 glioma cells. The results also revealed that higenamine significantly modulated the phosphoinositide-3-kinase/protein kinase B signaling cascade. Also, higenamine elevated the cysteine-aspartic proteases-3 and -9 and BCL2-associated X protein, and downregulated B-cell lymphoma 2 expression in the C6 glioma cells. Overall, the investigation suggests higenamine modulation of phosphoinositide-3-kinase/protein kinase B signaling pathway, nuclear factor-kappa B nuclear translocation, and caspase cascade in the C6 glioma cells.

The phytochemical characterization of the hydroalcoholic extract of Mangifera indica leaves L. cv. Kent (MS2) was determined by HPLC-ESI-QTOF-MS/MS. Eight metabolites were identified, these include: benzophenone derivatives and xanthones. Using ovariectomized rats (OVX), our findings suggest that EM2 exhibited an estrogenic effect by increasing the number of cornified cells in vaginal tissue. Furthermore, EM2 demonstrated a high antioxidant effect by reducing malondialdehyde (MDA) levels in OVX rat bone. We conclude that the polyphenolic compounds present in EM2 could increase the number of cornified cells and act as exogenous antioxidant agents against oxidative damage in OVX rats.

Acquired Immune Deficiency Syndrome. AIDS is medical condition . A person is diagnosed with AIDSwhen their immune system is too weak to fight off infection. AIDS is caused by HIV.The first case of HIV in India was reported in 1986 from Madras. Since then there has been an increase inthe number of HIV infections over the years. As per the National AIDS Control Organization (NACO), it isestimated that about 3.8 million people were living with HIV and AIDS in India in the year 2000.Exposure to human immunodeficiency virus (HIV) can be a consequence of many of the risk-takingbehaviors that occur among adolescents. Efforts to improve adolescent health through access to diagnosis,treatment and prevention education must take into account the developmental level of the patient, as well associal and psychological variables.Descriptive study to assess the knowledge of hypertensive patients regarding Transmission of AIDS amongadolescence was conducted by researcher.Objectives of the study:• To assess the knowledge of adolescence regarding the transmission of HIV/AIDS.• To find out the knowledge score towards mode of transmission and prevention of HIV/AIDS andselected socio demographic variables.The major findings of the study are -In knowledge section, majority of adolescence 9 (30%) were havinggood knowledge (09-12, marks with mean value 10.44), 8(26.7%) of them were having average knowledge(05-08, marks with mean value 6.87), 7(23.3%) of them were having poor knowledge (00-04 marks withmean value 3.57), 6(20%) of them having excellent knowledge (13-15 marks with mean value 13.3).It can be concluded that majority of adolescence have average knowledge and it can be improved by doingeffective adolescence health teaching in various health centers and community areas.

Accessing the contents of visual short-term memory (VSTM) is compromised by information bottlenecks and visual interference between memorization and recall. Retro-cues, displayed after the offset of a memory stimulus and prior to the onset of a probe stimulus, indicate the test item and improve performance in VSTM tasks. It has been proposed that retro-cues aid recall by transferring information from a high-capacity memory store into visual working memory (multiple-store hypothesis). Alternatively, retro-cues could aid recall by redistributing memory resources within the same (low-capacity) working memory store (single-store hypothesis). If retro-cues provide access to a memory store with a capacity exceeding the set size, then, given sufficient training in the use of the retro-cue, near-ceiling performance should be observed. To test this prediction, 10 observers each performed 12 hours across 8 sessions in a retro-cue change-detection task (40,000+ trials total). The results provided clear support for the single-store hypothesis: retro-cue benefits (difference between a condition with and without retro-cues) emerged after a few hundred trials and then remained constant throughout the testing sessions, consistently improving performance by two items, rather than reaching ceiling performance. Surprisingly, we also observed a general increase in performance throughout the experiment in conditions with and without retro-cues, calling into question the generalizability of change-detection tasks in assessing working memory capacity as a stable trait of an observer (data and materials are available at osf.io/9xr82 and github.com/paulzerr/retrocues). In summary, the present findings suggest that retro-cues increase capacity estimates by redistributing memory resources across memoranda within a low-capacity working memory store.

BACKGROUND & OBJECTIVE: Coronavirus disease (COVID-19) is a contagious disease that has shaken the mankind. Up till 30th June 2020, about 10.1 million people have been affected across 188 countries around the world. Deterioration of mental health is long-term effect of a pandemic. Methods for the control of COVID-19 have provoked fear, anxiety and frustration. Developed countries might be able to handle them but for a developing country it may prove an economic “Death Warrant”. Pakistan is one of countries that have been fighting with COVID-19, with about 24% of the population living below the national poverty line and aftermaths of this pandemic still awaits. We intend to assess impact of COVID-19 on mental health in Pakistan to contribute towards the prevention of anticipated complications by getting a more clear picture.

METHODOLOGY: Online literature search was carried out from Jan 2020 to Jun 2020, using Google Scholar, Science Direct and PubMed with the help of key words. This resulted in retrieval of 151 articles after removing duplicated ones. Articles with incomplete information, case reports, case series, letters or editorials were also excluded. After shortlisting, seven articles were finally selected for the review.

RESULTS: This review observed that mental illnesses have been potentiated by COVID-19 due to its multi-dimensional manifestations especially on the economic growth of the country. Health care professionals and those having previous history of any psychological disabilities are the easy targets.

CONCLUSION: COVID-19 disease management and preventive measures to provide psychological support must go hand in hand.

This paper describes the synthesis of highly active and selective catalysts based on natural coal: Jerusalem artichoke, camelina, rape and wheat, and their modification with nanosized iron, for cracking associated petroleum gases (APG) using the example of propane, for solving the ecological problem of environmental pollution and the economic problem of raw materials for the production of a huge range of polymer materials used by mankind in almost all spheres of life. With the help of APG catalysis, an environmental problem can be solved. By sending APG for processing to obtain light olefins for the production of polymeric materials. Currently, catalysts using nanoparticles show high performance in selectivity, product yield, and so on. As the physical properties of nanoparticles affect their catalytic properties, and how catalyst fabrication parameters can in turn affect these physical properties, nanocatalysts can be designed that are highly active, highly selective, and reasonably stable. Also activated carbons from natural plant raw materials have very good adsorption properties, but the nature and kinetics of adsorption are determined not only by the type of natural raw materials, but also by the temperature and other parameters of the technological characteristics of the carbon materials obtained. Also, the use of catalysts in this area is environmentally beneficial, since it allows you to reduce the temperatures of the cracking processes and increase the yield of products of interest. The elemental composition of catalytic systems has been established. The acidity of catalytic systems of both natural coals modified with iron and simple natural coals has been established. A high catalytic activity of modified catalytic systems was revealed – the conversion of associated petroleum gas reaches a maximum at 900 K. A high selectivity in the formation of olefins, about 95% at the maximum conversion, for the obtained catalysts was established.

Growing plants under conditions of closed soil using various technologies allowed physiologists to influence their metabolism. The most "environmentally friendly," and not fully studied, are technologies using light of various spectral composition that affects growth, leaf anatomy, secondary plant metabolites and chloroplast ultrastructure. The problem of directed regulation of components of the production process of phytocenoses during artificial irradiation is an urgent task. The authors have previously published data on the effect of ultraviolet radiation on the biochemical properties of plants. As a continuation of these studies, the purpose of the present work was to study the effect of various spectra of visible light on the antioxidant activity of plants. Influence of monochromatic LED irradiation of different wavelength at equal power of radiation on seed germination and change of total antioxidant activity of Abyssinian and sugar beets is studied in the paper. The level of antioxidant activity during sprouting in the light decreased by 17.8-26.7% compared to dark sprouting, which can serve as an indicator of a decrease in the level of stressful effects. At the same time, with an increase in the level of stress (in the red light version – a decrease in the biomass of 100 sugar beet sprouts by 41.8%), there was an increase in the total antioxidant activity by 8.6%, which, according to the literature, may be associated with the activation of plant antioxidant systems as an adaptive reaction to stress. The stimulating effect of irradiation of seeds and sprouts with green light (520 nm) is shown – increase of biomass of 100 sprouts by 45.8% of sugar beet compared to the recommended GOST dark germination, in nougat – by 27.8%. Genetic differences in the reaction of germination of seeds of two crops to monochromatic radiation of different wavelength are established and the need to develop differentiated modes of radiation of seeds when growing microzelenium is justified.
