Picea mexicana Martínez, P. chihuahuana Martínez y P. martinezii Patterson son especies endémicas de México en peligro de extinción. Se presenta una síntesis de su situación actual y una propuesta de manejo para su conservación in situ y ex situ, con base en la diversidad y estructura genética de las poblaciones y la ubicación de las áreas en donde se predice existirá el hábitat climático que les es propicio en el futuro (años 2030, 2060 y 2090; al promediar los modelos Canadiense, Hadley y Geofísica de Fluidos con escenarios de emisiones A y B). Para la conservación in situ se plantea la protección, el incremento de la diversidad genética y la expansión de las tres únicas poblaciones de P. mexicana, las cuatro únicas de P. martinezii y ocho poblaciones designadas prioritarias de las 40 poblaciones de P. chihuahuana, mediante la plantación de individuos originados de otras poblaciones hasta alcanzar un tamaño mínimo de población genéticamente viable (entre 1035 a 3836 individuos). Para la conservación ex situ se propone el establecimiento de poblaciones en sitios fuera del rango de distribución natural de las especies, en donde se ha proyectado que ocurrirá el clima que les es propicio, con al menos 3606 individuos de P. mexicana en el volcán Cofre de Perote, Veracruz; 2431 individuos de P. chihuahuana en el municipio de Guanaceví, Durango; y 3092 individuos de P. martinezii en la región de Tlatlauquitepec, Puebla, con plantas originadas de una mezcla de semillas colectadas de árboles al azar de poblaciones específicas.

Over the past years, the internet has broadened the horizon of various domains to interact and share meaningful information. As it is said that everything has its pros and cons therefore, along with the expansion of domain comes information overload and difficulty in extraction of data. To overcome this problem the recommendation system plays a vital role. It is used to enhance the user experience by giving fast and coherent suggestions. This paper describes an approach which offers generalized recommendations to every user, based on movie popularity and/or genre. Content-Based Recommender System is implemented using various deep learning approaches. This paper also gives an insight into problems which are faced in content-based recommendation system and we have made an effort to rectify them.

Published: July 2020

The sudden development of the COVID-19 pandemic exposed
the limitations in modern healthcare systems to handle public health
emergencies. It is evident that adopting innovative technologies such as
blockchain can help in effective planning operations and resource deployments. Blockchain
technology can play an important role in the healthcare sector such as improved
clinical trial data management by reducing delays in regulatory approvals,
streamline the communication between diverse stakeholders of the supply chain
etc. Moreover, the spread of misinformation has intensely increased during the
outbreak and existing platforms lack the ability to validate the authenticity
of data, causing people to panic and act irrationally. Thus, developing a
blockchain-based tracking system is important to ensure that the information
received by the public and government agencies are reliable and trustworthy. In
this paper, we focus on blockchain abilities to track the COVID-19 data
collected from various sources including news, healthcare professionals,
researchers etc, verify and append them in a secure and trusted distributed
ledger. Thus, we propose a generic framework using Ethereum smart contracts and
oracles to track real-time data related to the number of new cases, deaths and
recovered cases obtained from trusted sources. We present detailed algorithms
that capture the interactions between stakeholders in the network. The smart
contract code was developed and tested in Remix environment. We present the
cost and security analysis incurred by the stakeholders and highlight the
challenges and future directions of our work. Our work demonstrates that the proposed
solution is economically feasible and ensures data integrity, security, transparency,
data traceability among stakeholders.

Published: July 2020

Colorectal cancer is an aggressive malignancy for which there are limited treatment options. Oncolytic vaccinia virus is being developed as a novel strategy for cancer therapy. Arming vaccinia virus with immunostimulatory cytokines can enhance the tumor cell-specific replication and
antitumor efficacy. Interleukin-24 (IL-24) is an important immune mediator, as well as a broad-spectrum tumor suppressor. We constructed a targeted vaccinia virus of Guang9 strain harboring IL-24 (VG9-IL-24) to evaluate its antitumor effects. In vitro, VG9-IL-24 induced an increased number
of apoptotic cells and blocked colorectal cancer cells in the G2/M phase of the cell cycle. VG9-IL-24 induced apoptosis in colorectal cancer cells via multiple apoptotic signaling pathways. In vivo, VG9-IL-24 significantly inhibited the tumor growth and prolonged the survival both
in human and murine colorectal cancer models. In addition, VG9-IL-24 stimulated multiple antitumor immune responses and direct bystander antitumor activity. Our results indicate that VG9-IL-24 can inhibit the growth of colorectal cancer tumor by inducing oncolysis and apoptosis as well as
stimulating the antitumor immune effects. These findings indicate that VG9-IL-24 may exert a potential therapeutic strategy for combating colorectal cancer.

Published: July 2020

PURPOSE OF RESEARCH: The main objective of the study was to analyze the results of treatment of patients with cervical erosion and ectopia without surgical treatment.
MATERIALS AND METHODS: To this end, a complete clinical examination of women with cervical erosion and ectopia was carried out: A smear for oncocytology, PCR for HPV 16–18, herpes simplex virus, chlamydia, colposcopy extended, and bacteriological study to identify the vaginal microflora. As a result of examinations, 30% of women without specific symptoms and complaints were diagnosed with cervical ectopia and assigned to the first group (practically healthy women). About 68% of women were assigned to the second group – with cervical erosion, who need conservative treatment, 2% – to the third group – women with invasive cervical cancer, who were sent to the oncology center. About 82% of L-SIL developed against the background of infection with highly oncogenic types of HPV, most often HPV 16, with 30% of them infected with more than 1 type of HPV. To eliminate concomitant inflammation of the cervix and vagina, hexicon was used in this group. After the rehabilitation of the vagina and cervix, the next step was to connect the drug depantol.
RESULTS: The use of hexicon and depantol in the treatment of cervical erosion led to the regeneration of the defect of the cervical vaginal mucosa, bypassing the surgical treatment of cervical erosion.
THE NOVELTY OF THE RESEARCH: As a result of the treatment of uncomplicated ectopia, there was no need to apply a surgical method of treatment in connection with the healing of ectopia.
PRACTICAL APPLICATION OF THE STUDY: Such an approach to the treatment of women with cervical erosion among obstetrician-gynecologists would lead to the prevention of relapse and improve the quality of life of patients. After treating the cervix with solkovagin, healthy tissues begin to recover under these dead tissues, which in the process completely replace patients without scarring on the cervix.
The Effect of Progesterone Therapy in Severe Traumatic Brain Injury Patients on Serum Levels of s-100β, Interleukin 6, and Aquaporin-4
Authors: Mahyudanil Mahyudanil , Bajamal A. H. , Sembiring R. J. , Dharmajaya R.
Published: July 2020

BACKGROUND: Severe TBI is leading in death and disability worldwide. The initial stage resulted from direct tissue damage and impaired autoregulation of cerebral blood flow. The level of S-100β, IL-6 and AQ4 in CSF increased in neuronal injury and BBB damage. PROG effect is assessed on biomarkers of S-100β, IL-6, and AQP4.
AIM: The study examined the 1st to 4th day of progesterone administration.
METHODS: The sample consisted of 23 participants in the control group and 16 participants in the treated group. Patients with GCS 4–8, not surgical, aged 15-50 years, coming in the first 24 h and patient’s family agreed to this research are included. The sample was taken from the serum, and the biomarker processed using ELISA. GOS 3 months used as prognostic.
RESULTS: The result showed the mean value serum level of S100β, AQP4, and IL-6 increased on 24 h and 96 h after given PROG. Change of mean value of S100β day to day was 44.75 (96 h)–40.57 (24 h) – 4.18. In control group, change of S100β decrease to 42.51 (96 h)–46.11 (24 h) = −3.60, showing effect still unclearly proven in repairing neuronal injury, BBB disruption or another consideration on concentration of S100β, AQP4, and IL-6 in serum.
CONCLUSION: S-100β serum levels is significant to predict outcome of severe TBI. Progesterone still unclearly proven in repairing neuronal injury and/or BBB disruption. Another consideration is temporal trajectory of S100β, AQP4, and IL-6. In future study, natural endogenous PROG should be sought. S-100β in future pharmaceutical trials may be possible as pharmacological target.

Published: July 2020

Species identification of earthworms using morphology can be challenging and inconclusive as homoplasy in many characters is high. The use of molecular DNA technology, such as the use of conserved regions in mtDNA and nuclear DNA has unravelled the phylogenetic background of several earthworm species. The current study utilised the cytochrome c oxidase subunit I (COI) mitochondrial marker to reconstruct the phylogeny of Kazimierzus Plisko, 2006 species from the Western and Northern Cape provinces of South Africa. Phylogenetic reconstructions were implemented using Bayesian Inference, as well as Maximum Likelihood. Both tree building methods adhered to the monophyly of the majority of the taxa. Results showed that species fell into two clades and validated eleven currently known Kazimierzus species (K. circulatus (Plisko, 1998), K. franciscus (Pickford, 1975), K. guntheri (Pickford, 1975), K. hamerae (Plisko, 1998), K. kleinoodi Nxele & Plisko, 2017, K. nietvoorbiji Nxele & Plisko, 2017, K. nieuwoudtvillensis Nxele & Plisko, 2017, K. occidualis (Plisko, 1998), K. pearsonianus (Pickford, 1975), K. phumlani Nxele & Plisko, 2017, K. sophieae (Plisko, 2002)). Cryptic diversity is evident in K. occidualis with genetic divergence greater than 12% amongst populations. Kazimierzus franciscus and K. ljungstroemi (Pickford, 1975) have a low genetic variability suggesting close relatedness or probably conspecificity. A group of specimens from Clanwilliam are morphologically identical to K. sophieae, but are genetically distinct and may belong to undescribed species. This study demonstrates the importance of integrative taxonomy in earthworms in order to present reliable taxonomic and biogeographic data.
Variability and distribution of the golden-headed weevil Compsus auricephalus (Say) (Curculionidae: Entiminae: Eustylini)
Authors: Girón Jennifer , Chamorro M. Lourdes
Published: July 2020

The golden-headed weevil Compsus auricephalus is a native and fairly widespread species across the southern U.S.A. extending through Central America south to Panama. There are two recognised morphotypes of the species: the typical green form, with pink to cupreous head and part of the legs and the uniformly white to pale brown form. There are other Central and South American species of Compsus and related genera of similar appearance that make it challenging to provide accurate identifications of introduced species at ports of entry.

Here, we re-describe the species, provide images of the habitus, miscellaneous morphological structures and male and female genitalia. We discuss the morphological variation of Compsus auricephalus across its distributional range, by revising and updating its distributional range, based on data from entomological collections in the U.S.A. and Canada. The revised distribution of C. auricephalus extends as far south as Zacapa in Guatemala. Records south from there correspond to a different species, with affinities to C. auricephalus that we discuss and illustrate. We also discuss morphological affinities and differences with other similar species. Furthermore, we summarise information regarding the biology, host plants and natural enemies of C. auricephalus.
Les retraites et la création de la Sécurité sociale en 1945 : révolution ou restauration ?
Authors: Valat Bruno
Published: July 2020

La création de la Sécurité sociale en 1945 a été l’occasion d’une importante réforme de l’assurance vieillesse des salariés du secteur privé, à la base de notre système actuel. Les dispositifs existants depuis le début du siècle dans ce domaine n’avaient pas donné satisfaction pour deux raisons principales : d’abord le choix du principe contributif, qui imposait de longues années d’attente avant la jouissance d’une pension ; ensuite, les effets de l’inflation, qui avait laminé la valeur des cotisations capitalisées depuis 1910. Une reconstruction complète était donc nécessaire. L’article examine successivement les grandes questions que les réformateurs de la Libération durent résoudre pour donner des bases solides à la législation d’après-guerre et les choix opérés en la matière, notamment celui du régime financier à retenir : capitalisation ou répartition ? À la lumière de ces choix, il tente de répondre à la question : doit-on parler de révolution pour l’assurance vieillesse en 1945 ? Ne s’agit-il pas plutôt d’une restauration ?
Retraites : retour sur trente ans de débats et de réformes
Authors: Blanchet Didier
Published: July 2020

Quatre réformes du système de retraite ont eu lieu en France depuis 1993. Par rapport à ce qui était attendu au début des années 1990, l’équilibre du système a été à peu près rétabli en jouant à parts à peu près égales entre hausse du taux d’effort des actifs – déjà engrangé –, décalage progressif de l’âge de la retraite et décrochement progressif du niveau de vie relatif des retraités. Mais l’équilibre ainsi atteint reste sensible aux hypothèses de croissance économique et à ce que sera la trajectoire effective du vieillissement démographique.
Pierre de la Ramée, Loys Le Roy : deux philosophes français au milieu du XVI e siècle
Authors: Vuilleumier Antoine
Published: July 2020

Cette étude se propose en un premier temps de décrire les quelques contacts historiques entre Pierre de La Ramée et Loys Le Roy. Dans un second temps, à partir de leurs cas particuliers, l’article voudrait émettre quelques hypothèses sur les conditions de possibilité et les formes intellectuelles et textuelles que peut revêtir, au milieu du xvie siècle, une philosophie d’expression française, dont les nombreuses publications attestent la vitalité. Le recours à la langue française dans un contexte philosophique est déterminé par des préoccupations idéologiques et politiques, une philosophie orientée vers la praxis et l’exemple de Cicéron. Nourris par des idées communes, mais évoluant dans des milieux socioculturels distincts, Ramus et Regius illustrent la philosophie française par des modes d’expression et des objets d’étude très différents (traités théoriques sur le trivium pour l’un, traductions et commentaires platoniciens puis politiques pour l’autre).
« L’homme vit sur terre mais pense au ciel. ». Spiritualisme et catholicisme : le cas d’Émile Saisset
Authors: Milbach Sylvain
Published: July 2020

Émile Saisset (1814-1863) est un philosophe aujourd’hui bien oublié, bien qu’il ait été un insigne représentant de « l’école éclectique » qui a dominé l’enseignement de la philosophie en France entre 1820 et les années 1860. Au sein de cette école, il fut celui qui entretint avec le catholicisme un dialogue constant, et un des représentants les plus distingués du spiritualisme philosophique. Ce dialogue repose en partie sur la volonté de définir un nouveau magistère dans la société post-révolutionnaire, qui tienne à la fois compte de la tradition portée par le christianisme et des nécessités d’affronter la « modernité ». Il a rêvé d’un concordat philosophique avec le christianisme. Il y avait une part de stratégie dans cette démarche, et les contemporains, comme les philosophes de la fin du siècle, n’ont pas manqué d’y voir une part d’hypocrisie. En réalité, il y avait aussi dans sa démarche une « inquiétude métaphysique », reposant sur les modalités d’articulation entre foi et raison dans un régime de société d’opinions. Si Émile Saisset a été oublié, c’est parce que la séquence historique qu’il incarne a été ensevelie sous la laïcité républicaine. Et pourtant, sa pensée et son action témoignent pour la construction française d’une acception spirituelle et philosophique du gouvernement politique.
La(s) reforma(s) en el franciscanismo portugués en la Edad Media
Authors: Rodrigues Ana Maria S. A. , Inglês Fontes João Luís , Filomena Andrade Maria
Published: July 2020

En este artículo se analiza la reforma del franciscanismo portugués a finales de la Edad Media. Se trata de una reforma plural, realizada en un contexto de intensa renovación religiosa y espiritual, en el que emergen nuevas órdenes religiosas y los laicos participan intensamente creando nuevas formas de «pobre vida». Entre los Franciscanos masculinos, la Observancia surgió en la última década del siglo XIV en el norte de Portugal, traída por frailes gallegos y castellanos. El apoyo de la monarquía y de la nobleza cortesana dictó su rápida expansión a todo el reino, a través la reforma de conventos antiguos y la creación de nuevos. Entre las Clarisas, la reforma fue más tardía —solo se concretó a fines del siglo XV— y asumió dos formas: la entrega de la tutela de sus comunidades a los Observantes y la creación de nuevos monasterios sometidos a la primera regla de santa Clara y a las Constituciones coletinas. Todavía, en 1517, cuando el Papa separó los Franciscanos portugueses en dos ramas y entregó el gobierno de la orden a los Observantes, había ya llegado a tierras portuguesas un modelo aún más radical en su austeridad, el de la «estrechísima observancia», que experimentará una gran expansión en las siguientes décadas.

Santas y marcadas: itinerarios de lectura modélicos en las obras de las místicas bajomedievales impresas por Cisneros
Authors: Acosta-García Pablo
Published: July 2020

En este artículo nos acercamos al grupo de post-incunables de temática místico-devocional encomendados por el Cardenal Francisco Ximénez de Cisneros a través de un estudio de caso: el del Liber qui dicitur Angela de Fulginio de 1505, que además contiene el Liber specialis (o spiritualis) gratiae de Mechthild von Hackeborn y la Prima regula de Francisco de Asís. En primer lugar, analizamos qué versiones hace imprimir el Cardenal respecto a la tradición manuscrita europea de ambas obras. En segundo, discutimos la presencia de un posible programa reformista vinculado al ideario cisneriano a través de los fragmentos que marcan multitud de maniculae de imprenta a lo largo de los márgenes de las dos primeras obras.
Adorno et Althusser, lecteurs de Hegel
Authors: Vuillerod Jean-Baptiste
Published: July 2020

Cet article cherche à rapprocher les pensées de Louis Althusser et de Theodor W. Adorno autour de trois grandes questions : le primat de la théorie, la théorie de la société et de l’histoire, et la critique du sujet. Dans chaque cas, il s’agit de mettre en évidence les points communs entre les deux penseurs tout en soulignant leur désaccord fondamental en ce qui concerne la manière dont chacun se rapporte à la philosophie de Hegel. Là où Althusser vise à repenser le marxisme sur des bases non hégéliennes, Adorno veut au contraire revenir à Hegel pour ressourcer le marxisme en temps de crise.
Primates crop raiding situation on farmlands adjacent to South-West of Mole National Park, Ghana
Authors: Wiafe E. D.
Published: July 2020

Human activities have led to the overlapping of resource requirements among themselves and animal species and this often results in conflict. This research was conducted to determine the type of animal species involved in crop raiding, crops raided, the reasons for crop raiding events with its associated effects on the livelihoods of surrounding communities and the mitigation measures against it. 10 victims from eight communities were interviewed through a semi-structured guide. Though many animals were involved, the most troublesome and destructive were the following monkey species: Olive baboons (Papio anubis); Patas monkeys (Erythrocebus patas); and Green monkeys (Cercocerbus sabaeus). These monkeys raiding events were found to be based on the palatability of crops and the most adopted methods used in deterring them were shouting and trapping. Monkeys were found to raid crops at the various farms in the communities for diverse reasons and recommendations for peaceful coexistence of humans have been made.
Auroral classification ergonomics and the implications for machine learning
Authors: McKay Derek , Kvammen Andreas
Published: July 2020

Abstract. The machine-learning research community has focused greatly on bias in
algorithms and have identified different manifestations of it. Bias in
training samples is recognised as a potential source of prejudice
in machine learning. It can be introduced by the human experts who define
the training sets. As machine-learning techniques are being applied to
auroral classification, it is important to identify and address
potential sources of expert-injected bias. In an ongoing study,
13 947 auroral images were manually classified with significant
differences between classifications. This large dataset allowed for the
identification of some of these biases, especially those originating
as a result of the ergonomics of the classification process. These
findings are presented in this paper to serve as a checklist for
improving training data integrity, not just for expert
classifications, but also for crowd-sourced, citizen science
projects. As the application of machine-learning techniques to auroral
research is relatively new, it is important that biases are identified
and addressed before they become endemic in the corpus of training
data.
Coastal gradients south of Cape Town: what insights can be gained from mesoscale reanalysis?
Authors: Jury Mark R.
Published: July 2020

Abstract. Mesoscale datasets are used to study coastal gradients in the marine climate and oceanography south of Cape Town. Building on past work, satellite and ocean/atmosphere reanalysis are used to gain new insights on the mean structure, circulation and meteorological features. HYCOM v3 hindcasts represent a coastward reduction of mixing that enhances stratification and productivity inshore. The mean summer currents are westward –.4 m/s along the shelf edge and weakly clockwise within False Bay. The marine climate is dominated by southeasterly winds that accelerate over the mountains south of Cape Town and fan out producing dry weather. Virtual buoy time series in Dec 2012–Feb 2013 exhibit weather-pulsed upwelling in early summer interspersed with quiescent spells in late summer. Intercomparisons between model, satellite and station data build confidence that coupled reanalyses yield opportunities to study air-sea interactions in coastal zones with complex topography. The 0.083° HYCOM reanalysis has 16 data points in the embayment south of Cape Town, just adequate to resolve the coastal gradient and its impacts on ocean productivity.

Marine accidents as potential crisis situations on the Baltic sea
Authors: Szubrycht Tomasz
Published: July 2020

People responsible for crisis management, especially in coastal voivodships (Pomeranian, West Pomeranian and Warmian-Masurian Voivodeship) must be aware and prepared to take effective action in the event of emergencies in maritime waters. The geographical, hydro meteorological conditions and geographical conditions of the Baltic Sea of the Baltic Sea and the increasing intensity of Baltic shipping, and in particular the increase in oil transport, mean that the likelihood of maritime accidents that can generate crises in sea areas increases significantly. There are about 2000 ships in the Baltic marine area at any given moment and about 3500 - 5500 ships navigate through the Baltic Sea per month. Approximately 20% of the ships in the Baltic Sea are tankers. Despite different uncertainties some trends in the Baltic shipping can be expected. For example ship traffic is likely to increase yearly and it is expected that vessel size will increase because the maritime transport must be more efficient and cost-saving. Such trends create serious threats for Baltic States. The maritime administrations of the Baltic States and international maritime organizations undertake a number of actions to increase maritime safety in the Baltic Sea. The publication characterizes Baltic shipping and analyzes the scale of threats generated by maritime accidents, as well as ways of responding and minimizing the probability of emergencies in the Baltic Sea. Activities including: legislative and organizational activity were also characterized; practical use of modern technology both on vessels and in land navigation monitoring systems; marine traffic engineering and shipbuilding, which aim is to minimize the likelihood of maritime accidents in the Baltic Sea and analyses of Baltic states capacity to oil spill response. In addition, the publication proposes a definition of a crisis situation in relation to sea areas and presents when a maritime accident or incident can generate a crisis situation in sea areas. The result of the research process is proposals for actions that, in the author's opinion, should be taken to reduce the number of maritime accidents in the Baltic Sea.

Authors: Sánchez Romero Cristina , López Berlanga Maria Carmen
Published: July 2020

Los jóvenes adolescentes se encuentran inmersos en las redes sociales a través de sus dispositivos móviles. El objetivo de la investigación se centra en analizar la percepción de actitudes nocivas entre los jóvenes adolescentes en las redes sociales. Para ello, se han seleccionado una muestra de 202 estudiantes del nivel educativo de secundaria obligatoria a quienes se les ha aplicado un cuestionario mixto (alfa 0.78) del que se ha seleccionado las unidades de información cualitativa de la narrativa de los informantes claves. Los resultados muestran que los estudiantes han percibido agresiones a través de insultos y amenazas por compartir archivos fotográficos (46.03 %) en las principales redes sociales como son Instagram (61.4 %) y WhatsApp (26.2 %). Estas agresiones que sufren los estudiantes se pueden solventar si se desarrolla una formación en la inclusión digital desde edades tempranas. Esto permitirá un uso adecuado de los dispositivos móviles y una comunicación e intercambio de información en las redes sociales desde actitudes positivas. Se requiere una inclusión digital de los estudiantes para el uso crítico de los archivos que comparten a través de las redes sociales. 

The teenagers are immersed in social networks through their mobile devices. The objective of the research focuses on analyzing the perception of harmful attitudes among young adolescents in social networks. To do this, a sample of 202 students of compulsory secondary education level have been selected, to whom a mixed questionnaire (alpha 0.78) has been applied, from which the qualitative information units of the narrative of the key informants have been selected. The results show that students have perceived aggressions through insults and threats by sharing photographic files (46.03 %) in the main social networks such as Instagram (61.4 %) and WhatsApp (26.2 %). These aggressions suffered by students can be solved if a training in digital inclusion is developed from an early age. This will allow an adequate use of mobile devices and a communication and exchange of information in social networks from positive attitudes. It requires a digital inclusion of students for the critical use of the files they share through social networks.
Sharing for science: high-resolution trophic interactions revealed rapidly by social media
Authors: Maritz Robin A. , Maritz Bryan
Published: July 2020

Discrete, ephemeral natural phenomena with low spatial or temporal predictability are incredibly challenging to study systematically. In ecology, species interactions, which constitute the functional backbone of ecological communities, can be notoriously difficult to characterise especially when taxa are inconspicuous and the interactions of interest (e.g., trophic events) occur infrequently, rapidly, or variably in space and time. Overcoming such issues has historically required significant time and resource investment to collect sufficient data, precluding the answering of many ecological and evolutionary questions. Here, we show the utility of social media for rapidly collecting observations of ephemeral ecological phenomena with low spatial and temporal predictability by using a Facebook group dedicated to collecting predation events involving reptiles and amphibians in sub-Saharan Africa. We collected over 1900 independent feeding observations using Facebook from 2015 to 2019 involving 83 families of predators and 129 families of prey. Feeding events by snakes were particularly well-represented with close to 1,100 feeding observations recorded. Relative to an extensive literature review spanning 226 sources and 138 years, we found that social media has provided snake dietary records faster than ever before in history with prey being identified to a finer taxonomic resolution and showing only modest concordance with the literature due to the number of novel interactions that were detected. Finally, we demonstrate that social media can outperform other citizen science image-based approaches (iNaturalist and Google Images) highlighting the versatility of social media and its ability to function as a citizen science platform.

Objectives: This study aims to investigate in secondary databases the prevalence of TB / HIV co-infection in the elderly in the metropolitan region of Belém-Pará, Brazil, in the 2001-2018 historical series.

Methodology: This is an epidemiological, retrospective study with a quantitative approach. Data collection was carried out in the database of SINAN/TB (Notifiable Information System/ Tuberculosis) of the State Secretariat of Public Health (SESPA), using records of confirmed cases of tuberculosis in the elderly in the metropolitan region of Belém, between 2001 and 2018, available for public consultation.

Results: 110 cases of co-infection were found in the elderly between 2001 and 2018 in the Metropolitan Region of Belém, with a predominance of males, aged between 60 and 69 years, mixed race and ignored/blank education. The clinical-epidemiological variables resulted in the prevalence of new cases and in the pulmonary clinical form, in addition to the absence of information in the extrapulmonary form.

Conclusion: The elderly are more vulnerable to pulmonary tuberculosis and HIV infection, and the presence of co-infection in this population is extremely harmful and even fatal. Therefore, conducting early detection is essential for disease prevention, in addition to educational activities aimed at promoting information about the two pathologies, promoting self-responsibility for health, higher rates of appropriate treatment and better cure rates.
Transformative Experiences
Authors: Arvan Marcus
Published: July 2020

Transformative experiences are experiential states that radically alter a person in some way, such as what the person can know or understand, their core values or preferences, their overall outlook on the world, and so on. Notable historical examples plausibly include the Apostle Paul's epiphany and sudden conversion to Christianity on the road to Damascus, St. Augustine's moral and spiritual transformation after the death of a close friend, and similar transformations by the Buddha and Muhammed. Such experiences have been argued to pose philosophical challenges for rational choice, as it appears unclear how one can make rational life‐choices about experiences one does not understand or which otherwise fundamentally transform oneself or one's values. Some theorists argue that rational choices involving transformative experiences are impossible. Others argue that transformative experiences instead pose a challenge to making choices that are both rational and authentic. Others still are unconvinced that transformative experiences pose any serious or unique problems to rational choice, contending that the problems they present are either exaggerated or reducible to problems unrelated to transformative experience. Finally, many solutions have been advanced for resolving the problems that transformative experiences are alleged to pose, including that transformative experiences can be chosen for their own sake, chosen on the basis of objective evidence such as statistics and testimony, chosen on the basis of imaginative comparison to relevantly similar past experiences, or, alternatively, be rationally grappled with by the development of internal mastery such as personal resilience or through moral behavior.
Capacitive monitoring system for real‐time respiratory motion monitoring during radiation therapy
Authors: Sadeghi Parisa , Moran Kathryn , Robar James L.
Published: July 2020

This work introduces a novel capacitive‐sensing technology capable of detecting respiratory motion with high temporal frequency (200 Hz). The system does not require contact with the patient and has the capacity to sense motion through clothing or plastic immobilization devices.

Purpose

This work presents and evaluates a novel capacitive monitoring system (CMS) technology for continuous detection of respiratory motion during radiation therapy. This modular system provides real‐time motion monitoring without any contact with the patient, ionizing radiation, or surrogates such as reflective markers on the skin.

Materials and methods

The novel prototype features an array of capacitive detectors that are sensitive to the position of the body and capable of high temporal frequency readout. Performance of this system was investigated in comparison to the RPM infrared (IR) monitoring system (Varian Medical Systems). The prototype included three (5 cm × 10 cm) capacitive copper sensors in one plane, located at a distance of 8–10 cm from the volunteer. Capacitive measurements were acquired for central and lateral‐to‐central locations during chest free‐breathing and abdominal breathing. The RPM IR data were acquired with the reflector block at corresponding positions simultaneously. The system was also tested during deep inspiration and expiration breath‐hold maneuvers.

Results

Capacitive monitoring system data demonstrate close agreement with the RPM status quo at all locations examined. Cross‐correlation analysis on RPM and CMS data showed an average absolute lag of 0.07 s (range: 0.03–0.23 s) for DIBH and DEBH data and 0.15 s (range: 0–0.43 s) for free‐breathing. Amplitude difference between the normalized CMS and RPM signal during chest and abdominal breathing was within 0.15 for 94.3% of the data points after synchronization. CMS performance was not affected when the subject was clothed.

Conclusion

This novel technology permits sensing of both free‐breathing and breath‐hold respiratory motion. It provides data comparable to the RPM system but without the need for an IR tracking camera in the treatment room or use of reflective markers on the patient.

The development of materials capable of varying macroscale ligand distributions can emulate an extracellular matrix (ECM) remodeling and regulate the adhesion and polarization of macrophages. In this report, negatively charged slidable nano‐ligands are assembled and then conjugated to a positively charged substrate via electrostatic interaction. The negatively charged slidable nano‐ligands are prepared by coating magnetic nanoparticles with a polymer linker and negatively charged RGD ligand. The nano‐ligand sliding is characterized under an external magnetic field, which spatiotemporally alters macroscale ligand density. To the best of knowledge, this is the first demonstration that magnetic maipulation of the macroscale ligand density inhibits inflammatory M1 phenotype but stimulates the adhesion and regenerative M2 phenotype of host macrophages. Furthermore, it is elucidated that the magnetic attraction of the slidable nano‐ligand facilitates the assembly of adhesion structures in macrophages, thereby stimulating their regenerative M2 phenotype. The design of ECM‐emulating materials that allow remote, spatiotemporal, and reversible controllability of macroscale ligand density provides an appealing strategy in the spatiotemporal regulation of immunomodulatory tissue‐regenerative responses to implants in vivo.

Creating colloids of liquid metal with tailored dimensions has been of technical significance in nano‐electronics while a challenge remains for generating supranano (<10 nm) liquid metal to unravel the mystery of their unconventional functionalities. Present study pioneers the technology of pulsed laser irradiation in liquid from a solid target to liquid, and yields liquid ternary nano‐alloys that are laborious to obtain via wet‐chemistry synthesis. Herein, the significant role of the supranano liquid metal on mediating the electrons at the grain boundaries of perovskite films, which are of significance to influence the carriers recombination and hysteresis in perovskite solar cells, is revealed. Such embedding of supranano liquid metal in perovskite films leads to a cesium‐based ternary perovskite solar cell with stabilized power output of 21.32% at maximum power point tracing. This study can pave a new way of synthesizing multinary supranano alloys for advanced optoelectronic applications.

Published: July 2020

Stretchable and flexible electronic devices can be worn on the human body or incorporated into clothing. They have promising applications in the field of wearable electronics, flexible displays, and stretchable circuits. Here, a smart sensor based on multiwalled carbon nanotubes (MWCNTs) coated with zinc oxide (ZnO) nanoparticles (NPs) and embedded in polydimethylsiloxane is reported. The smart sensor based on MWCNT/ZnO nanohybrid particles can measure a wide range of temperature (0–100 °C). The concentration of MWCNT and ZnO NP size is chosen in such a way that the sensor shows a stable and linear response to change in temperature and other deformation with high selectivity. The smart sensor has a negative temperature coefficient with a sensitivity of −33.6 kΩ °C−1, and bending movement sensitivity of the sensor is measured with different sizes of ZnO NP and can be tuned from 33.3 to 138.89 kΩ degree−1. The robust and high performance shown in this study makes the demonstrated sensor competitive for a variety of applications, including body motion detection, health monitoring, and robotics.
