Une identité réinterprétée : Notes sur un vieux documentaire et recherche autour de l’identité macanaise
Authors: Kin Man Cheong
Published: March 2021

The present paper, originating from its author’s innocent search for his identity in his twenties as a postcolonial yearning for an emotion-driven, if not unconsciously voluntary, cultural self-colonization, appears ten years later as a self-reflexive and self-critical essay. It can be read as a piece of postcolonial literature apart, or as a commentary to his documentary Ou Mun Ian, Macaenses (2009) and its textual research (2010). This quest, if not construction or invention of identity, resonated with a cross-epochal public discourse which transcended Macau’s last colonial years and its first postcolonial decade, that Macau was never a colony but a unique result from a China-West exchange. Originally to mark the tenth anniversary of the postcolonial Macau, between 2008 and 2009, the author, who was a great yet naïve admirer of the domestic exoticism and the colonial nostalgia of the mix-blood Portuguese Macanese, travelled across Portugal, Canada, US and Brazil to create a project from filmed interviews in the diaspora, in a government-sponsored adventure which let to the author’s self-discovery. This very amateur thirty-three-minute documentary largely shaped the author’s earlier belief in his undecolonizability and his later extended search and creation of his multiplying beliefs inside an Eurocentric expansion of an European universe.
Monumentos Virtuais: projeto audiovisual colaborativo para formato fulldome
Authors: Oliveira Andreia Machado , Camargo Matheus Moreno dos Santos , Zindela Luyanda
Published: March 2021

This article presents the “Virtual Monuments” project that explores alternative modes of video production and projection, investigating other media, formats and practices. Our fulldome project is a collaborative interdisciplinary project jointly produced by the Federal University of Santa Maria/Labinter (Santa Maria, Brazil), Durban University of Technology/ Interdisciplinary Lab (Durban, South Africa) and the Federal University of Ceará (Fortaleza, Brazil). The aim of this project is to use the planetariums or different surfaces in these cities as sites for the projection of digital monuments collaboratively produced and shared between the three participating cities. Monuments are usually considered structures that occupy public spaces as cultural symbols commemorating important figures, events or elements of a culture´s heritage. Monuments can also be seen as sites where power can either be enforced or contested. The Virtual Monuments project was produced jointly as an experiment in multi-sited, collaborative, interdisciplinary creation between the three participating institutions in order to expand our understanding of the dynamic collaborative processes of ideation, creation, production, participation exhibition and reception. Each site contributed and participated in the creation of the others’ artworks, each one sharing their creativity and know-how to collectively realize these monuments as a tentative siting of dissolution of hierarchies and power structures within institutional creative environments. The project has been showcased in international events such as “Understanding Visual Music - UVM” at the Galileo Galilei Planetarium of Buenos Aires, “DIGIFEST” at Durban University of Technology, and “EFEMERA” at the UFSM Planetarium in Brasil.
Enquadrando o Rural – A busca de narrativas na construção de um documentário sobre o lugar dos Amiais, Portugal
Authors: Pereira Rodolfo Gomes , Oliveira Lídia , Amaro Ana Carla
Published: March 2021

This paper covers the making of a documentary film about LOCUS - Playful Connected Rural Territories, a project developed by the University of Aveiro, and the projects relations with the land of Amiais, a small village in central Portugal where 20 people, mainly seniors, live. LOCUS’ objective is to develop a way to use the internet of things as means to promote intergenerational interaction while exploring and learning about rural territories’ cultural heritage.In a first moment, we make a short reflection over the portraits of rural Portugal in documentary films and after we focus on the process of conception and production of a short documentary film about rural Portugal.We found out that there are several ways to frame the rural. A series of preconceived ideas dominate what we perceive as the countryside and the people that live in it. Those social representations are often marked by an idea of immutability, like the rural is the same as it always was, a place that is frozen in time when, in truth, the rural has been going through several changes in its landscape, changes that are provoking a sort of identity crisis.
Data Analysis Using Representation Theory and Clustering Algorithms
Authors: Alkhushayni Suboh , Choi Taeyoung , Alzaleq Du’a
Published: March 2021

This work aims to expand the knowledge of the area of data analysis through both persistence homology, as well as representations of directed graphs. To be specific, we looked for how we can analyze homology cluster groups using agglomerative Hierarchical Clustering algorithms and methods. Additionally, the Wine data, which is offered in R studio, was analyzed using various cluster algorithms such as Hierarchical Clustering, K-Means Clustering, and PAM Clustering. The goal of the analysis was to find out which cluster's method is proper for a given numerical data set. By testing the data, we tried to find the agglomerative hierarchical clustering method that will be the optimal clustering algorithm among these three; K-Means, PAM, and Random Forest methods. By comparing each model's accuracy value with cultivar coefficients, we came with a conclusion that K-Means methods are the most helpful when working with numerical variables. On the other hand, PAM clustering and Gower with random forest are the most beneficial approaches when working with categorical variables. All these tests can determine the optimal number of clustering groups, given the data set, and by doing the proper analysis. Using those the project, we can apply our method to several industrial areas such that clinical, business, and others. For example, people can make different groups based on each patient who has a common disease, required therapy, and other things in the clinical society. Additionally, for the business area, people can expect to get several clustered groups based on the marginal profit, marginal cost, or other economic indicators.

Diagnosis and treatment of complications, assessment of the relationship of factors associated with the development of these pathological conditions were carried out. Results. A comprehensive assessment of the parameters revealed that age over 50 years, the presence of proven antiphospholipid syndrome (AFS) were independently associated with a higher frequency of adverse surgical outcomes and in-hospital complications. Older age and a history of smoking were independently associated with a greater likelihood of developing reperfusion pulmonary edema. The probability of developing transient neurological complications is independently associated with a long duration of deep hypothermic circulatory arrest (DHCA), an increased level of D-dimer. A greater age and longer duration of ventilation are independently associated with the likelihood of developing acute kidney injury (AKI). A higher level of antithrombin III and the presence of AFS were independently associated with the likelihood of developing prolonged ventilation. Conclusion. When selecting candidates for surgery, in addition to the generally accepted clinical and instrumental parameters, it is necessary to take into account a history of Smoking, an increase in d-dimer, and the presence of AFS. Patients with this pathology need a more thorough risk assessment, correction of target levels of activated partial thromboplastin time (aPTT), activated clotting time (ACT) due to their falsely inflated indicators, and further development of standards for perioperative support. The main principle of cardiological support of the operation is the earliest possible diagnosis of all known perioperative complications and the rapid start of their treatment, which ensures the stabilization of the patient’s condition in 85% of cases in the hospital period. In the postoperative period, an early transition from ventilator to independent breathing is indicated for the prevention of associated complications, including AKI.
Photon-dominated Hydrodynamics

Some subtle distinctions between optically thin emission and optically thick emission (with a dynamically passive source of opacity) from an emitting surface are drawn. It is noted that photons may escape a region of high optical depth by dragging the opaque material with them, and that optically thick emission can have a shorter scale of variation than optically thin emission and less light echoing.

Interchange reconnection has been proposed as a mechanism for the generation of the slow solar wind, and a key contributor to determining its characteristic qualities. In this paper we study the implications of interchange reconnection for the structure of the plasma and field in the heliosphere. We use the Adaptively Refined Magnetohydrodynamic Solver to simulate the coronal magnetic evolution in a coronal topology containing both a pseudostreamer and helmet streamer. We begin with a geometry containing a low-latitude coronal hole that is separated from the main polar coronal hole by a pseudostreamer. We drive the system by imposing rotating flows at the solar surface within and around the low-latitude coronal hole, which leads to a corrugation (at low altitudes) of the separatrix surfaces that separate open from closed magnetic flux. Interchange reconnection is induced both at the null points and separators of the pseudostreamer, and at the global helmet streamer. We demonstrate that a preferential occurrence of interchange reconnection in the “lanes” between our driving cells leads to a filamentary pattern of newly opened flux in the heliosphere. These flux bundles connect to but extend far from the separatrix-web (S-Web) arcs at the source surface. We propose that the pattern of granular and supergranular flows on the photosphere should leave an observable imprint in the heliosphere.
Diurnal Variability and Detectability of Vegetation Red Edge of Earth-like Exoplanets
Authors: Wang Fei , He Jinping
Published: March 2021

The vegetation red edge (VRE) is a unique spectral fingerprint of light-harvesting vegetation on Earth and provides a robust remote detectable surface biosignature of exoplanets. To improve the detectability and sensitivity, we have studied the diurnal variability of VRE in the disk-integrated spectra of Earth and also Earth analogs in the case of different observing geometry conditions. Simulation results show that the VRE index varies from <−0.4 to >0.6 at a diurnal timescale for both present and also Late Triassic Earth, and the maximum variation of VRE in 1 day changes by >3 times with different observing geometry conditions. This means that the extraterrestrial light-harvesting vegetation (even if it really exists) will not be efficiently detectable without proper observing geometry conditions and time, especially in the case of the exoplanets covered with thick clouds. The VRE temporal variation curve can also be used to retrieve the cloud cover fraction and continent distribution of exoplanets with relatively high precision. Several observational strategies are proposed to detect the light-harvesting vegetation and retrieve the planetary information from the planet’s VRE variation signals, and a mock observation is also demonstrated.
LOFAR Observations of a Jet-driven Piston Shock in the Low Solar Corona

The Sun produces highly dynamic and eruptive events that can drive shocks through the corona. These shocks can accelerate electrons, which result in plasma emission in the form of a type II radio burst. Despite the large number of type II radio burst observations, the precise origin of coronal shocks is still subject to investigation. Here, we present a well-observed solar eruptive event that occurred on 2015 October 16, focusing on a jet observed in the extreme ultraviolet by the Atmospheric Imaging Assembly (SDO/AIA), a streamer observed in white light by the Large Angle and Spectrometric Coronagraph (SOHO/LASCO), and a metric type II radio burst observed by the LOw Frequency Array (LOFAR). LOFAR interferometrically imaged the fundamental and harmonic sources of a type II radio burst and revealed that the sources did not appear to be cospatial, as would be expected from the plasma emission mechanism. We correct for the separation between the fundamental and harmonic using a model that accounts for scattering of radio waves by electron density fluctuations in a turbulent plasma. This allows us to show the type II radio sources were located ∼0.5R
⊙ above the jet and propagated at a speed of ∼1000 km s−1, which was significantly faster than the jet speed of ∼200 km s−1. This suggests that the type II burst was generated by a piston shock driven by the jet in the low corona.

Introduction: The advent of Cone Beam Computed Tomography (CBCT) in endodontics has enhanced the diagnosis of periapical radiolucencies and the assessment of endodontically treated teeth. 

Aim: The purpose of this study was to assess the prevalence of periapical radiolucencies in a Bulgarian subpopulation and the quality of previous endodontic treatment using CBCT scans.

Materials and methods: This study included 2795 roots from 160 Large FOV CBCT which were evaluated by two independent examiners using two scoring systems: CBCT-PAI and PESS. 

Results: The inter-examiner agreement spanned from strong to almost perfect (0.892 and 0.983). The prevalence of periapical lesions according to the two scoring systems was 23.1% and 12.9 %, respectively. The prevalence of endodontically treated teeth was high (34.1%). Sixty-five percent of them presented with signs of periapical radiolucencies, while only 1.4% of all non-treated roots had a periapical lesion. A significant association between periapical disease, poor quality of the root canal filling and inadequate coronal seal was found (p<0.001). 

Conclusions: The prevalence of periapical disease in endodontically-treated teeth in the Bulgarian subpopulation was high. Poor qual-ity of the root canal filling and inadequate coronal seal were assessed as prognostic determinants of treatment failure. CBCT techniques can augment conventional diagnostic techniques in the field of endodontics. 
Antimicrobial properties, anti-virulence activities, and physico-mechanical characteristics of orthodontic adhesive containing C-phycocyanin: a promising application of natural products
Authors: Pourhajibagher Maryam , Bahador Abbas
Published: March 2021

Introduction: Antimicrobial orthodontic adhesives aim to reduce enamel demineralization, white spot lesions, and incipient tooth decay around bonded orthodontic brackets, but they should not imperil its mechanical properties. 

Aim: To evaluate the antimicrobial and physico-mechanical properties of acrylic containing different concentrations of C-phycocyanin on Streptococcus mutans, Lactobacillus acidophilus, and Candida albicans.

Materials and methods: The mechanical properties of acrylic resins were measured by flexural strength test after preparation of acrylic resin samples with concentrations of 1%, 2%, 5%, 7.5%, and 10% of C-phycocyanin. Then we evaluated the antimicrobial effects of acrylic resin containing the maximum concentration of C-phycocyanin with clinically acceptable flexural strength and the changes in expression of virulence factors.

Results: The highest and lowest means of flexural strength were obtained in acrylic resins containing 0% and 10% concentrations of C-phycocyanin at 50.2±4.5 and 30.1±3.3 MPa, respectively. Adding 1%, 2%, and 5% of C-phycocyanin showed no significant decrease in flexural strength (p>0.05). The maximum mean diameter of the growth inhibition zone was observed around discs containing 5% of C-phycocyanin. Until day 30 of the study, no microbial biofilms were formed on any acrylic disc. Only microbial biofilms of C. albicans were able to form on discs containing 5% of C-phycocyanin at 90 days. 5% C-phycocyanin could significantly decrease the expression levels of gtfB, hsp16, and ALS9 6.1-, 7.3-, and 3.9-fold, respectively.

Conclusions: It can be concluded that the most acceptable concentration of C-phycocyanin in acrylic resin is 5% based on the results of flexural strength tests and antimicrobial activities of acrylic resin containing various concentrations of C-phycocyanin.

16p11.2 duplication syndrome is a rare disorder, often associated with intellectual disability, attention deficit, hyperactivity disorder, and a predisposition to epilepsy and schizophrenia. There are no specific dysmorphic features for this genetic condition, but micro-cephaly, micrognathia and hypertelorism could be present. We report a case of 16p11.2 duplication syndrome which has the typical clinical presentation – slight facial dysmorphism, impaired intellectual development, and autistic behavior. Whole-exome sequencing was performed, but no pathogenic or likely pathogenic mutations were identified. Array comparative genomic hybridization analysis established the diagnosis of 16p11.2 duplication syndrome, which illustrates the importance of this method when diagnosing children with unexplained intellectual disability.
