Public Procurement of Innovation A Cultural Challenge
Authors: Valadares Tavares Luís
Published: December 2021

The promotion of innovation is a key objective of modern public policies promoting sustainable development and public procurement of innovation can be considered as a strategic instrument of such policies as it is clearly expressed by the recent EU Directives on public procurement. The concept and the requirements of public procurement of innovation (PPI) are studied in this paper identifying traditional obstacles to its dissemination and suggesting several initiatives allowing an easier application of this concept compromising legal traditions with innovative rules. Special attention is given to the new Portuguese legal framework transposing 2014 Directives focusing on its new potential but also on shortcomings that should be corrected shortly.
The Level of utilization and Satisfaction of Complete Denture Treatment Provided in Fiji from 2010-2016
Authors: Kajal Kartika , Mohammadnezhad Masoud , Sivaramakrishnan Gowri , Bhai Kritesh , Khan Sabiha
Published: December 2021

BACKGROUND: Wearing dentures helps rehabilitate the oral health status for the older people. Due to lack of previous data, this objective of this study was to determine the level of utilization and satisfaction of complete denture treatment at dental clinics in Fiji.

MATERIALS & METHODS: A cross sectional descriptive study was conducted on 85 edentulous patients and dentures at the Fiji National University (FNU) teaching dental clinic from 2010-2016.Patients who utilized the dentures fabricated at FNU and identified as complete denture patients from 2010-2016 were included in this study. Data was collected using the denture assessment form and Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT) questionnaire. Correlation test was done and p less than 0.05 was considered as level of significance.

RESULTS: Participants were between the age range of 40-79 years with majority being male (54%). Greater level of satisfaction noted among 60-69 years male participants and those wearing the dentures for 3-4 years than other groups. Difficulty in chewing (40%) and food catching underneath the denture (33%) were common denture related complains. One thirds of participants reported of uncomfortable dentures while 24% had sore spots due to their dentures. More than two thirds of them, (71%) were unable to eat and enjoy food and for most patients, the vertical dimension (94%), esthetics assessment (94%), tooth selection (91%), boarder extension (78%), posterior seal (99%) and centric relation (99%) were acceptable. Patients with acceptable vertical dimension (46.1±7.6), acceptable esthetics (45.8±7.9) and boarder extension (48.0±7.2) showed greater satisfaction level compared to those with unacceptable denture characteristics.

CONCLUSION: This study highlighted that satisfaction among recent denture wearers was low and majority participants portrayed poor understanding regarding denture aftercare and hygiene. It can be recommended for the teaching institutes and dental clinics to evaluate the quality of treatments and help to improve the quality of services being provided to the patients. Further study is needed to determine the in- depth perceptions of denture wearers. It also can be recommended for the patients to take heed of the post operative denture hygiene instructions being given.
De dynamiek van sluipende crises: meekoppelen van klimaatbeleid met besluiten van vandaag
Authors: de Gooyert Vincent , de Coninck Heleen

On the dynamics of creeping crises: Coupling climate policies with today’s decisions

Addressing a creeping crisis like climate change requires nothing less than a system transition. A system transition is very complex and hence its success depends to a large extent on feedback effects: mechanisms where an initial change reinforces itself or balances itself out. Urgent crises are more salient than creeping crises. However, it is possible to combine policies for both urgent and creeping crises, as can be seen in policies that aim for a green recovery. In this article, we conclude that up till now such policies have overlooked the relevance of feedback effects. We provide examples of corona recovery measures that simultaneously help to establish a system transition through feedback effects.

Comunicação informal e o sucesso de projetos de desenvolvimento software: um estudo de caso no setor bancário brasileiro
Authors: Rezende Leandro Zocaratto , Parada Vasques Prado Edmir , Grotta Alexandre
Published: December 2021

O gerenciamento de projetos de tecnologia é desafiador. Apesar da comunicação ser um dos fatores mais importantes para o sucesso de um projeto, há poucos trabalhos na literatura que relacionam a comunicação informal (CI) com sucesso em projetos. Esta pesquisa tem como objetivo analisar a influência da CI no sucesso de curto e médio prazo de projetos de desenvolvimento de software em uma instituição bancária brasileira. Para atingir esse objetivo, fez-se uma revisão bibliográfica sobre o tema de comunicação e sucesso em projetos. A pesquisa possui uma abordagem qualitativa e utilizou estratégia de estudo de caso. Foram entrevistados doze profissionais de desenvolvimento de software no primeiro semestre de 2019. A pesquisa constatou uma associação entre CI com eficiência do projeto e contribuição para a equipe do projeto. Não foi constatada associação entre CI e contribuição para o cliente. Além disso, a CI apresentou mais contribuições nos projetos com abordagem cascata do que em projetos ágeis.
Foco no cliente em times de desenvolvimento de software: um estudo quantitativo
Authors: Ribeiro Fabio Calegari , Larieira Cláudio Luis Carvalho , Yoshikuni Adilson Carlos , Costa Ivanir
Published: December 2021

No início dos anos 2000 o Manifesto Ágil consolidou as práticas ágeis como contraponto ao modelo tradicional de gestão de projetos, considerando entre outras, a colaboração com o cliente e a aceitação às mudanças durante o processo de desenvolvimento de software como princípios básicos. Muitas empresas têm implementado métodos ágeis por influências externas e internas à organização, mas não capturam os principais benefícios da filosofia e continuam focando em eficiência ao invés de eficácia, através da perspectiva utilizada nos modelos tradicionais de gestão de projetos, levando à questão sobre quais fatores são mais importantes ao implementar métodos ágeis com foco no cliente. O objetivo desta pesquisa é avaliar os fatores que influenciam os times ágeis de desenvolvimento na obtenção de foco no cliente. Para avaliar estes fatores foi elaborado um questionário, que foi respondido por profissionais das áreas de TI e negócios que tem ou tiveram contato com métodos ágeis, no Brasil. Os resultados demonstram entre os fatores coleta e entendimento de requisitos, coleta e uso de informações do cliente, recebimento e utilização de feedback do cliente e relacionamento com o cliente quais possuem maior e menor efeito na mensuração do foco no cliente em times ágeis, contribuindo com os profissionais que implementam métodos ágeis em suas organizações para atingir um dos principais objetivos destes métodos, que é a satisfação do cliente.

VR Neuro Game: a Virtual Reality Game to Support Neuroanatomy Teaching and Learning
Authors: Souza Vinícius , Maciel Anderson , Nedel Luciana , Kopper Regis , Loges Klaus , Schlemmer Eliane
Published: December 2021

Using virtual environments (VEs) is a safer and cost-effective alternative to training people in different contexts. Immersive Virtual Reality (VR), combined with game aspects, have the potential to improve the user experience in the VE by increasing realism, engagement, and motivation. In education, there is a consensus about its contribution in the teaching and learning processes. However, in Brazil, only a few research groups have developed projects that involve the development of VR for education, due to technical difficulties and high costs. This manuscript presents the development and evaluation of an VR serious game to support the learning of neuroanatomy, an extended version of our previously published paper at the SVR 2020. In this version, we present the results of four different user studies, involving 57 participants, which suggest that the VR Neuro Game is easy to use, even by inexperienced subjects in VR, and is potentially useful for teaching and learning processes, both by individual students and groups of students and also in remote learning. In addition, the game was considered fun and did not cause discomfort. When comparing the knowledge test performance before and immediately after the experiments, we found significant difference only for the virtual condition. The same could be observed for retention results.

Published: December 2021

This paper presents the project of a large multi-genre treebank for Brazilian Portuguese, called Porttinari. We address relevant research questions in its construction and annotation, reporting the work already done. The treebank is affiliated with the “Universal Dependencies” international model, widely adopted in the area, and must be the basis for the development of state of the art tagging and parsing systems for Portuguese, as well as for conducting linguistic studies on morphosyntax and syntax for this language.
Utilizando um dicionário morfológico para expandir a cobertura lexical de uma gramática do português no formalismo HPSG
Authors: Nunes Ana Luiza , Rademaker Alexandre , Alencar Leonel Figueiredo de
Published: December 2021

Ampla cobertura lexical constitui um dos pré-requisitos para a robustez de uma gramática computacional. Propomos uma metodologia para povoar a tabela de formas verbais irregulares da PorGram (gramática do português no formalismo HPSG) utilizando os dados do dicionário MorphoBr. Nós implementamos um algoritmo que classifica as formas verbais do MorphoBr em regulares e irregulares, aplicando as regras ﬂexionais da PorGram. Avaliamos o algoritmo com numa amostra de 38 verbos, regulares e irregulares, obtendo os resultados esperados. Uma contribuição adicional foi o melhoramento do MorphoBr, com a eliminação de mais de 270.000 entradas erradas e a inclusão de quase 13.000 entradas faltantes.

Authors: Romualdo Alan da Silva , Real Livy , Caseli Helena de Medeiros
Published: December 2021

O aprendizado multimodal visa explorar as características das diversas modalidades (texto, imagem, áudio) para gerar modelos computacionais. No comércio eletrônico, devido à grande variedade das características dos produtos e à ausência ou inconsistência de informações, a combinação de informações de modos diferentes vem a ser bastante adequada. Neste trabalho são apresentados alguns experimentos para a classificação multimodal (texto e imagem) de produtos (produtos adultos) que não podem ser vendidos no marketplace da empresa parceira. Nesses experimentos, redes neurais foram usadas para treinar classificadores uni e multimodal. O classificador multimodal atingiu 99% de F1 contra 98% do modelo textual e 94% do visual.
Measuring Brazilian Portuguese Product Titles Similarity using Embeddings
Authors: Romualdo Alan da Silva , Real Livy , Caseli Helena de Medeiros
Published: December 2021

Textual similarity deals with determining how similar two pieces of texts are, considering the lexical (surface forms) or semantic (meaning) closeness. In this paper we applied word embeddings for measuring e-commerce product title similarity in Brazilian Portuguese. We generated some domainspecific word embeddings (using Word2Vec, FastText and GloVe) and compared them with general-domain models (word embeddings and BERT models). We concluded that the cosine similarity calculated using the domain-specific word embeddings was a good approach to distinguish between similar and nonsimilar products, but the multilingual BERT pre-trained model proved to be the best one.

Tackling neural machine translation in low-resource settings: a Portuguese case study
Authors: Estrella Arthur T. , Souza Filho João B. O.
Published: December 2021

Neural machine translation (NMT) nowadays requires an increasing amount of data and computational power, so succeeding in this task with limited data and using a single GPU might be challenging. Strategies such as the use of pre-trained word embeddings, subword embeddings, and data augmentation solutions can potentially address some issues faced in low-resource experimental settings, but their impact on the quality of translations is unclear. This work evaluates some of these strategies on two low-resource experiments beyond just reporting BLEU: errors are categorized on the Portuguese-English pair with the help of a translator, considering semantic and syntactic aspects. The BPE subword approach has shown to be the most effective solution, allowing a BLEU increase of 59% p.p. compared to the standard Transformer.

Published: December 2021

Neste trabalho, investiga-se o comportamento sintático-semântico do verbo "falar" no português brasileiro (PB) em um corpus jornalístico e em três bases de dados verbais do PB (VerbNet.Br, VerboWeb e Verbo-Brasil). Os dados demonstram a polivalência e complexidade de "falar". Além disso, no que se refere à análise das bases de dados, foi possível constatar a necessidade de revisões manuais, realizadas por linguistas, e/ou ampliações das descrições linguísticas, principalmente ao considerar a relevância de construções com o verbo "falar" para diferentes aplicações na área de Processamento de Língua Natural.

Published: December 2021

Este artigo descreve a instanciação das diretrizes do modelo Universal Dependencies (UD) para a anotação de Numerais em português. Mostramos a importância de conhecer o tópico a ser instanciado no contexto de várias línguas, uma vez que a anotação UD tem por objetivo promover, o máximo possível, o paralelismo entre as línguas. Exploramos então a descrição dos numerais nas gramáticas, buscando subsídios para elaborar instruções para atribuir a etiqueta NUM da UD. Os resultados da combinação das diretrizes da UD com as características dos numerais em português são apresentados em detalhes, com exemplos, juntamente com os argumentos que amparam cada decisão tomada.
Philosophical concept of the state power (social power) and the military (the armed force)
Authors: Kajtez Ilija
Published: December 2021

In the paper the author would like to explain why the concept of the social power is relevant for the state power, and why it is more appropriate for the military to talk about the armed force. Although he is acutely aware of the intertwining, reciprocity and closeness of the state power and the organization of the military, as well as the concepts of power and force, the author would like to emphasize their differences. It is not possible to talk about the power without the help and reliance on the armed force, and there is no armed force that does not view its meaning, task and goal in the state power. The military power can be independent only in short periods, but it immediately returns to the state power or the very military establishes the state power because it needs a source of legitimacy. What is the first and main rule is that we cannot talk anywhere about true power unless the one in power controls the armed force in his community, tribe, family, class, politics, state and society. It is simply impossible to imagine, let alone really happen, that the one who rules a community or society is not the supreme commander of the armed forces, as well. The main idea is to consider what are the inviolable spheres of the society in which politics should dominate, and where the best field of action of the armed forces is and how and in what way their relations, which are close, but often tense, are regulated.
Less invasive transoral resection of esophageal fibrovascular polyps: case reports
Authors: Włodarczyk Janusz , Smęder Tomasz
Published: December 2021

We report five patients treated for esophageal fibrovascular polyps using a minimally invasive technique. Esophageal fibrovascular polyps are benign pedunculated submucosal tumors of considerable size. The treated polyps size ranged from 1.5 to 13 cm. The polyps were removed by relocation to the oral cavity under endoscopic control. No perioperative complications occurred after the treatment. The follow-up of patients after surgery was 9–89 months, with no evidence of polyp recurrence. Thus, the described treatment is safe but requires experience with endoscopy as well as esophageal surgery.
Sustainability of Tobacco Treatment Programs in the Cancer Center Cessation Initiative
Authors: _ _
Published: December 2021

The NCI’s Cancer Center Cessation Initiative (C3I) has a specific objective of helping cancer centers develop and implement sustainable programs to routinely address tobacco cessation with patients. Sustaining tobacco treatment programs requires the maintenance of (1) core program components, (2) ongoing implementation strategies, and (3) program outcomes evaluation. NCI funding of C3I included a commitment of resources toward sustainability. This article presents case studies to illustrate key strategies in developing sustainability capacity across 4 C3I-funded sites. Case studies are organized according to the domains of sustainability capacity defined in the Clinical Sustainability Assessment Tool (CSAT). We also describe the C3I Sustainability Working Group agenda to make scientific and practical contributions in 3 areas: (1) demonstrating the value of tobacco use treatment in cancer care, (2) identifying implementation strategies to support sustainability, and (3) providing evidence to inform policy changes that support the prioritization and financing of tobacco use treatment. By advancing this agenda, the Sustainability Working Group can play an active role in advancing and disseminating knowledge for tobacco treatment program sustainability to assist cancer care organizations in addressing tobacco use by patients with cancer within and beyond C3I.
New software for the statistical analysis and qualification of NIST Charpy verification specimen lots
Authors: Lucon Enrico
Published: December 2021

New software, in the form of Microsoft Excel 2016 spreadsheets, has been created for the analysis and qualification of Charpy Verification Lots, to be used by personnel of the Charpy Verification Program at NIST in Boulder, Colorado. The new spreadsheets replace the previously used statistical software (in SYSTAT and R-code), adding a more detailed outlier analysis. Of the two spreadsheet templates, the first one assesses the acceptability of a Charpy pilot or production lot by calculating its sample size and identifying statistical outliers. The second spreadsheet establishes the reference value of absorbed energy and the associated uncertainty for the whole Charpy Verification Lot. Both spreadsheets have been checked and validated against calculations performed on several lots by means of the previously used R-language codes, which had been prepared by Jolene Splett of the Statistical Engineering Division of NIST.
Lavmælte Lillehammer og frenetiske Florø
Authors: Meyer Frank
Published: December 2021

Lokalhistorie skrives som regel uten noen informasjon om stedets spesielle lydbilde. Mulige årsaker til dette kan være at denne informasjonen vurderes som irrelevant, sjølsagt og uforanderlig eller at en ikke vet hvordan et lydbilde kan beskrives. I denne artikkelen argumenteres det for at lydbildet er en viktig sanselig stedserfaring som ikke er sjølsagt eller uforanderlig. Dette demonstreres ved å kontrastere de fundamentalt forskjellige lydskapene eller klanguniversene i to ellers kommensurable norske lokalsamfunn (Florø og Lillehammer). Videre presenterer artikkelen modeller og begrep fra to sentrale lydteoretikere, Raymond Murray Schafer og Bernie Krause, som viser hvor lett og givende det kan være å beskrive lokale lydskap. Artikkelen tar særlig sikte på å ta i bruk Bernie Krauses holistiske forestilling om lydøkologi, det vil si at et lokalt lydbilde er en integrert helhet av geofoni, biofoni og antropofoni.
Pricing Strategies – Comparative Analysis of Non-Exporting Enterprises and of Intense Exporters Based on the Example of Polish SMEs
Authors:   Warsaw School of Economics, Oleksiuk Adam
Published: December 2021

The research aim of the paper is to verify the differences with regard to the pricing strategies being implemented among non-exporting enterprises and intense exporters based on the example of Polish SMEs. The study presented was conducted between May – June 2019 on a representative sample of Polish SMEs created after 2004: non-exporters and exp orters with a min. 25% share of exports in the total sales. The research method applied is computer assisted web interviewing (CAWI) and computer assisted telephone interviewing (CATI). The total count of the sample is 240 businesses, randomly selected from a database which contains 2969 Polish companies. The study emphasizes that between exporting companies and non-exporting companies, there are differences in the pricing strategy application. Exporting enterprises more frequently have a differentiated pricing policy. No significant connection between the pricing strategy and the quality strategy was observed, both among non-exporting enterprises and intense exporters.

Economics and Economic Order of Societies
Authors:   Faculty of Management, University of Warsaw, Hockuba Zbigniew
Published: December 2021

Departing from the distinction proposed by J. Buchanan between thinking in economics in terms of the theory of choice and analysis in categories of exchange and coordination, we claim that the Hayekian concept of economic order has a significant heuristic potential and can be fruitfully used to explain some important socio-economic phenomena. The goal of this paper is to confirm this claim through the application of the concept of economic order in the analysis of economic transformation and the discussion of the relation between economic order and moral norms. The paper is organised as follows. Section I contains introductory remarks. In section II, the two systems of economic thinking and reasoning: the theory of choice and analysis in categories of exchange and coordination are briefly presented. Section III contains a discussion of the concept of economic order, its origin, relation to the Freiburg School notion Ordo, and J. Buchanan’s perspective on the market and exchange. In section IV, two areas of the application of the concept of economic order are presented: a) systemic transformation as a change in formal and informal institutions, their subjective representation by economic agents and the complex economic order, b) a relation between economic order and moral norms. Conclusions are drawn in section V.
Before a teenager starts to change the world. Adolescent entrepreneurship: a systematic literature review
Authors:   Uniwersytet Warszawski, Wydział Zarządzania, Simborowski Grzegorz
Published: December 2021

Adolescence is a period of heightened search for one’s identity and formation of one’s psychosocial self. Is this significantly different from entrepreneurial experimentation and identification of market opportunities? The main goal of this systematic literature review was to discover the existing body of knowledge about adolescent entrepreneurship, to identify a potential research gap, and to identify existing trends. The result indicates that in the eyes of most researchers, entrepreneurship has nothing in common with the joyful process of creating something new without looking at the resources available. They try to convince us that adolescents need to be prepared for entrepreneurship – properly nurtured, shaped and educated.
Dérivées variables : mathématiques et littérature au XXIe siècle. Vers un lyrisme stochastique
Authors: Surin Guillaume
Published: December 2021

Ce travail s’ancre dans le retard, déploré par Kenneth Goldsmith, qu’ont pris les pratiques littéraires sur les pratiques artistiques dans la période contemporaine. L’application du terme de stochastique, issu des mathématiques, associé aux notions de probabilités, de combinatoire, permet de penser les dispositifs mis en oeuvre par certains écrivains pour déployer les possibilités enfermées dans le langage. Ces applications, plus ou moins rigoureuses, d’un dispositif mathématique conduisent à penser des pratiques d’écriture autant créatrices que libératrices. Culminant dans l’écriture d’une machine elle-même dirigée par des algorithmes, elles ouvrent à la possibilité d’un lyrisme stochastique qui, en suspendant les fonctions du langage, en permet la contemplation, au-delà de toute actualisation. Autant de dispositifs lyriques rendant à la poésie sa capacité de libération des dispositifs qui nous contraignent.

L’Année galante (1785) ou le reflet d’un « miroir à putains » : portrait du marquis de Létorière en femme entretenue
Authors: Duriau Nicolas
Published: December 2021

Tandis qu’abondent les travaux consacrés aux filles de joie, leurs équivalents masculins semblent avoir été relégués dans la marge de l’histoire littéraire. À ce jour, aucune étude ni monographie ne retrace en effet l’évolution de ces personnages, apparus dès l’Antiquité. Bien avant leur entrée dans les dictionnaires français, ces « prostitués », comme nous les appellerions désormais, sont très présents dans la littérature, en particulier celle du XVIIIe siècle. En 1785, un texte anonyme intituléL’Année galante ou les intrigues secrètes du marquis de L***brosse le portrait de l’un de ces hommes entretenus aux dépens des femmes. Aussi reflète-t-il une figure historique, Armand Prévost de Létorière, ainsi qu’un fait social aujourd’hui méconnu : le « guerluchonnage », ancien témoignage d’une prostitution masculine au service de ces dames.
Comment peut-on être rousseau ? Étude de la perception de la rousseur au siècle des Lumières
Authors: André Valérie
Published: December 2021

« Il est si naturel de penser que c’est la couleur qui constitue l’essence de l’humanité, que les peuples d’Asie, qui font les eunuques, privent toujours les noirs du rapport qu’ils ont avec nous d’une façon plus marquée. On peut juger de la couleur de la peau par celle des cheveux, qui, chez les Égyptiens, les meilleurs philosophes du monde, étaient d’une si grande conséquence, qu’ils faisaient mourir tous les hommes roux qui leur tombaient entre les mains. » La citation de L’Esprit des lois est célèbre. Montesquieu ne laisse subsister aucun doute quant à la véracité des faits qu’il rapporte. À l’en croire, dans l’ancienne Égypte, la prévention contre les individus convaincus de délit de rousseur confinerait au génocide ! Or notre philosophe n’est pas homme à traiter l’érudition avec désinvolture. Consignée au titre d’exemplum a contrario, la cruauté absurde des « meilleurs philosophes du monde » semble être tenue pour argent comptant, et l’extermination systématique des personnes rousses pour pratique avérée. La prévention qui touche la rousseur est ancestrale : méchanceté, lubricité, félonie, odeur nauséabonde, caractère démoniaque, on ne compte plus les avatars du préjugé. Cette étrange fascination faite d’attraction et de répulsion s’est perpétuée de siècle en siècle, un peu partout dans l’occident chrétien, comme une rumeur qui se construit et enfle, jusqu’à la démesure, au point de devenir une vérité unanimement reconnue, et finalement indiscutable. Pourfendeur des superstitions et des outrages faits à la Raison, le XVIIIe siècle allait-il imposer un frein à la circulation d’une idée reçue aussi stupide qu’inconvenante ? Tout encouragerait à le croire, si le retour aux textes ne bémolisait l’optimisme spontané du chercheur et ne l’encourageait à l’exercice de la prudence. Comment peut-on être rousseau au siècle des Lumières ? Telle est la question à laquelle cette étude s’efforcera de répondre. Ne pas tuer les roux conduirait au génocide.
Ensaios fora do tubo: a saúde e seus paradoxos
Authors: Castiel Luis David
Published: December 2021

Tempos distópicos pedem textos corajosos e muitas vezes academicamente inconvenientes. Se seu livro pode fazer surgir um sorriso de canto de boca nos pares, ele também serve como uma escrita-molotov a ser usada na guerrilha científica. Isso porque ele aposta que a melhor proposição, a melhor solução, é o exercício da crítica. Sabe a mania que temos de construir nossos artigos com aquele trecho que precisa responder à pergunta: “Ah, tá! Mas o que você propõe no lugar disso que você está criticando?”. Esta obra nos põe a pensar se o ponto de partida epistemológico dessa pergunta talvez devesse ser outro...
A regurgitalite of the Middle Triassic (Muschelkalk) from Upper Silesia (Poland)

Published: December 2021

A bromalite from the Middle Triassic (Muschelkalk) of southern Poland, Sadowa Góra Quarry, is herein described and interpreted as a regurgitalite. The fossils occurring within the regurgitalite are angular and have sharp edges. They are represented by common fragments of thin-shelled bivalves as well as rare crinoid and gastropod remains. The composition of the collected inclusion is different from that of the host rock. There are many candidates that could have produced the regurgitalite, including durophagous sharks, marine reptiles, the actinopterygian Colobodus, or nautiloids. Our finding adds to the emerging evidence of durophagous predation in the Triassic sea of Polish part of the Germanic Basin. It is the second record of a regurgitalite from the Muschelkalk of Upper Silesia.

The aim of the study was to assess the risk posed by Legionella bacteria in a public building in Krakow. An old building with internal installation risers of different ages, as well as draw-off points of different types, was selected for testing. Samples were collected during two campaigns. In one sample of the first series of tests, no bacteria were found. During the second series of tests, no Legionella bacilli were found in just one sample and in one sample only 4 colony-forming units were detected. At the remaining draw-off points (water taps), the bacteria count detected were greater than the maximum threshold allowed by legal regulations (admissible threshold for public utility buildings – 100 cfu/100 mL). No morphological differences were observed with respect to the occurrence of specific serogroups. In 14 samples, Legionella pneumophila serogroups 2–14 were found, while the Legionella pneumophila serogroup 1 was only found in one sample. The risk assessment was also carried out based on a semi-quantitative risk matrix approach and as a quantitative microbial risk assessment. The risk matrix approach was successfully implemented for the recognition of the potential risk associated with the Legionella occurrence in a water system. The calculated annual cumulative risk is high. The research shows that even if the weekly inhalation exposure dose (and therefore the calculated risk) is high, the number of Legionella pneumophila illness cases found can be equal to zero. This is probably due to the large uncertainty associated with QMRA determination. The size of the room in which the contaminated water is used also affects the possibility of infection.

Joint inversion is a widely used geophysical method that allows model parameters to be obtained from the observed data. Pareto inversion results are a set of solutions that include the Pareto front, which consists of non-dominated solutions. All solutions from the Pareto front are considered the most feasible models from which a particular one can be chosen as the final solution. In this paper, it is shown that models represented by points on the Pareto front do not reflect the shape of the real model. In this contribution, a collective approach is proposed to interpret the geometry of models retrieved in inversion. Instead of choosing single solutions from the Pareto front, all obtained solutions were combined in one “heat map”, which is a plot representing the frequency of points belonging to all returned objects from the solution set. The conducted experiment showed that this approach limits the problem of equivalence and is a promising way of representing the geometry of the model that was retrieved in the inversion process.

Axon loss underlies symptom onset and progression in many neurodegenerative disorders. Axon degeneration in injury and disease is promoted by activation of the NAD-consuming enzyme SARM1. Here, we report a novel activator of SARM1, a metabolite of the pesticide and neurotoxin vacor. Removal of SARM1 completely rescues mouse neurons from vacor-induced neuron and axon death in vitro and in vivo. We present the crystal structure of the Drosophila SARM1 regulatory domain complexed with this activator, the vacor metabolite VMN, which as the most potent activator yet known is likely to support drug development for human SARM1 and NMNAT2 disorders. This study indicates the mechanism of neurotoxicity and pesticide action by vacor, raises important questions about other pyridines in wider use today, provides important new tools for drug discovery, and demonstrates that removing SARM1 can robustly block programmed axon death induced by toxicity as well as genetic mutation.
The population genetics of collateral resistance and sensitivity
Authors: Ardell Sarah M , Kryazhimskiy Sergey
Published: December 2021

Resistance mutations against one drug can elicit collateral sensitivity against other drugs. Multi-drug treatments exploiting such trade-offs can help slow down the evolution of resistance. However, if mutations with diverse collateral effects are available, a treated population may evolve either collateral sensitivity or collateral resistance. How to design treatments robust to such uncertainty is unclear. We show that many resistance mutations in Escherichia coli against various antibiotics indeed have diverse collateral effects. We propose to characterize such diversity with a joint distribution of fitness effects (JDFE) and develop a theory for describing and predicting collateral evolution based on simple statistics of the JDFE. We show how to robustly rank drug pairs to minimize the risk of collateral resistance and how to estimate JDFEs. In addition to practical applications, these results have implications for our understanding of evolution in variable environments.
Artificial Intelligence in the Analysis of Upper Gastrointestinal Disorders
Authors: Bang Chang Seok
Published: December 2021

In the past, conventional machine learning was applied to analyze tabulated medical data while deep learning was applied to study afflictions such as gastrointestinal disorders. Neural networks were used to detect, classify, and delineate various images of lesions because the local feature selection and optimization of the deep learning model enabled accurate image analysis. With the accumulation of medical records, the evolution of computational power and graphics processing units, and the widespread use of open-source libraries in large-scale machine learning processes, medical artificial intelligence (AI) is overcoming its limitations. While early studies prioritized the automatic diagnosis of cancer or pre-cancerous lesions, the current expanded scope of AI includes benign lesions, quality control, and machine learning analysis of big data. However, the limited commercialization of medical AI and the need to justify its application in each field of research are restricting factors. Modeling assumes that observations follow certain statistical rules, and external validation checks whether assumption is correct or generalizable. Therefore, unused data are essential in the training or internal testing process to validate the performance of the established AI models. This article summarizes the studies on the application of AI models in upper gastrointestinal disorders. The current limitations and the perspectives on future development have also been discussed.
Gastric Ulcer Bleeding associated with a Left Gastric Artery Pseudoaneurysm
Authors: Kang Seokin , Kim Yuri , Choi Kee Don
Published: December 2021

A left gastric artery (LGA) pseudoaneurysm is known to occur as a complication of abdominal surgery, trauma, or pancreatitis. However, an LGA pseudoaneurysm presenting with gastrointestinal bleeding is rare. A 77-year-old man complained of dizziness and three episodes of melena in the last 24 hours. He did not have a history of surgery, trauma, or pancreatitis. He underwent primary coronary intervention for unstable angina and started dual antiplatelet therapy 1 month prior. Esophagogastroduodenoscopy (EGD) revealed a 3-cm ulcer in the lesser curvature of the gastric high body with a pulsating subepithelial tumor-like lesion in the ulcer. Hemostasis was achieved endoscopically. Three days after the endoscopic hemostasis, hematemesis and hypovolemic shock occurred. Emergent angiography of the superior mesenteric artery revealed an LGA pseudoaneurysm with extravasation. Coil embolization was successfully performed. Three days after the angiographic embolization, EGD revealed improvement of the gastric ulcer, which was covered with exudate, and disappearance of the subepithelial tumor-like lesion. At the 2-month follow-up, EGD showed that the ulcer was in the healing stage.

Background: Amniotic fluid is the liquid which surround the fetus after the first few weeks of gestation. Amniotic fluid is derived mostly from the fetus and has many functions that are essential for normal growth and development. The aim of this work is to study the relation between fetal renal artery flow velocity waveforms and amniotic fluid volume in normal pregnancies and those complicated by oligohydramnios.

Methods: This prospective observational study was carried out on 40pregnant women (10) of them were with normal amount of amniotic fluid (group I), while (30) of them suffered from oligohydramnios (group II).By using color doppler ultrasound imaging, the fetal renal circulation can be assessed. Intermittent assessment of renal artery flow velocity waveforms during the early stages of pregnancy may help in predicting changes in amniotic fluid dynamics.

Results: There was a non-significant difference between cases with normal amount of amniotic fluid and cases with oligohydramnios in Gestational age, Maternal age, fetal femur length, bi parietal diameter, abdominal circumference and Fetal weight. There were increased values of fetal renal artery Resistance index (RI) and Pulsatility index (PI) in cases of oligohydramnios than cases with normal amount of amniotic fluid. There was no correlation between Peak systolic velocity (PSV) and Amniotic fluid index (AFI). There was a significant difference in End diastolic velocity (EDV) between cases with normal amount of amniotic fluid and cases with oligohydramnios. Also, there was a significant difference in Systolic diastolic ratio (S/D) and Amniotic fluid index (AFI) between cases with normal amount of amniotic fluid and cases with oligohydramnios.

Conclusions: There is a relation between renal artery flow velocity waveforms and oligohydramnios using Pulsed wave Doppler Ultrasonography. There are higher values of renal artery Resistance index and Pulsatility index in cases of oligohydramnios more than cases with normal amount of amniotic fluid.
