Authors: Liu Guang , Du Qiang , Liu Jun , Wang Pei , Wang RuoNan , Lian ZengYan
Published: February 2020

In typical median and small aeroengines, the air used to realize the functions such as cooling of turbine blades and disks, sealing of turbine cavities and bearing chambers, adjusting of rotating assembly axial load is normally drawn through the rear cavity of centrifugal impeller, so the thorough understanding of flow characteristics and pressure distribution and the proposal of the corresponding control methods in the cavity are the key to design the rational secondary air system. With an impeller rear cavity in a small turbofan engine as an object, the current study was dedicated to the investigation of flow control methods in the cavity. Two methods, namely, baffle and swirl-controlled orifice, were proposed to regulate the pressure loss and distribution in the cavity. Furthermore, the influence of geometry parameters of the two methods such as the length of baffle, the space between the baffle and rotating disk wall, the orientation, and radial position of swirl-controlled orifice was investigated. The CFD results show that the swirl-controlled orifice which could deswirl the flow is more effective in regulating the pressure loss and its distribution in cavity than baffle. The variation of the radial position of the swirl-controlled orifice had little influence on pressure loss but obvious influence on pressure distribution; therefore, decreasing the radial position could reduce the axial load on the rotating disk without changing the outlet pressure.

Purpose. To investigate the impact of surgical delay after the objectivation of the foveal status by spectral-domain optical coherence tomography (SD-OCT) on visual outcomes in patients with rhegmatogenous retinal detachment (RRD) with foveal involvement. Methods. A retrospective dataset analysis of 508 eyes of 504 consecutive patients with primary RRD was performed. The primary outcome measure was the best-corrected visual acuity as a function of time between the assessment of the foveal status with SD-OCT upon initial examination at the department and RRD repair. Results. In total, 188 eyes (37.0%) had a complete foveal detachment and 31 (6.1%) eyes had a bisected fovea by the retinal detachment. A hundred eyes with total foveal detachment received surgery within 24 h and 65 eyes between 24 h and 72 h. Visual outcomes for eyes with detached fovea were significantly better when treated within 24 h (0.47 ± 0.39) compared with those treated between 24 h and 72 h (0.84 ± 0.66; p=0.01) after objectivation of the foveal status with SD-OCT. Pars plana vitrectomy was performed in 174 (92.6%) eyes and scleral buckling surgery in 14 (7.4%) eyes with complete foveal involvement of RRD. Conclusions. Our findings suggest improved visual outcomes for patients receiving surgery within 24 h after a definitive diagnosis of fovea-involving RRD compared to surgical interventions that were further delayed.

Published: February 2020

The decision-making process of complex clinical cases should involve multiple specialists to obtain a predictable result on a long-term basis. In view of the above, the present report is aimed at describing the multidisciplinary management of a partially edentulous female patient presenting with a severely compromised residual dentition. To improve function and aesthetics, the treatment combined multiple extractions, temporary rehabilitation with a complete removable denture, guided bone regeneration and implant insertion, soft tissue management, tooth alignment, and restorative dentistry. Thus, several dental branches were embraced during the treatment phases, including oral surgery and implantology, periodontology, orthodontics, and prosthodontics. The involvement of different specialists ensured the achievement of a good result from biological, functional, and aesthetic aspects. The patient was satisfied with the final outcome. In conclusion, to meet the patient’s expectations particularly in complex clinical situations, the interdisciplinary approach becomes essential from the early phases in order to identify the ideal treatment plan with the correct time sequence.
Exosomal miRNA‐215‐5p Derived from Adipose‐Derived Stem Cells Attenuates Epithelial–Mesenchymal Transition of Podocytes by Inhibiting ZEB2
Authors: Jin Juan , Wang Yunguang , Zhao Li , Zou Wenli , Tan Mingming , He Qiang
Published: February 2020

Background. Podocyte migration is actively involved in the process of podocyte loss and proteinuria production, which is closely associated with the development of diabetic nephropathy (DN). Exosomes from adipose‐derived stem cells (ADSCs‐Exos) effectively inhibit podocyte apoptosis in the treatment of DN. However, how ADSCs‐Exos affect the migration of podocytes is obscure. This study is aimed at exploring the regulatory role of ADSCs‐Exos on cell migration and the underlying mechanism. Methods. ADSCs‐Exo was authenticated by transmission electron microscopy (TEM), western blotting, and flow cytometry. Cell viability and migration ability of podocytes were measured by CCK8 and Transwell assays, respectively. Relative expressions of miRNAs and mRNAs were determined by qRT‐PCR. The transmitting between PKH26‐labeled exosome and podocytes was evaluated by IF assay. Dual luciferase reporter assay was employed to detect the relationship between miR‐215‐5p and ZEB2. Results. The exposure to serum from DN patient (hDN‐serum) significantly inhibited cell viability of podocytes, but ADSCs‐Exo addition notably blunts cytotoxicity induced by the transient stimulus of hDN‐serum. Besides, ADSCs‐Exo administration powerfully impeded high glucose‐ (HG‐) induced migration and injury of podocyte. With the podocyte dysfunction, several miRNAs presented a significant decline under the treatment of HG including miR‐251‐5p, miR‐879‐5p, miR‐3066‐5p, and miR‐7a‐5p, all of which were rescued by the addition of ADSCs‐Exo. However, only miR‐251‐5p was a key determinant in the process of ADSCs‐Exo‐mediated protective role on podocyte damage. The miR‐251‐5p inhibitor counteracted the improvement from the ADSCs‐Exo preparation on HG‐induced proliferation inhibition and migration promotion. Additionally, miR‐215‐5p mimics alone remarkably reversed HG‐induced EMT process of podocyte. Mechanistically, we confirmed that ADSCs‐Exos mediated the shuttling of miR‐215‐5p to podocyte, thereby protecting against HG‐induced metastasis, possibly through inhibiting the transcription of ZEB2. Conclusion. ADSCs‐Exo has the protective effect on HG‐evoked EMT progression of podocytes thru a mechanism involving ZEB2. Potentially, the ADSCs‐Exo preparation is a useful therapeutic strategy for improving podocyte dysfunction and DN symptoms clinically.

Published: February 2020

In this paper, in order to handle the nonlinear system and the sophisticated disturbance in the marine engine, a finite-time convergence control method is proposed for the diesel engine rotating speed control. First, the mean value model is established for the diesel engine, which can represent response of engine fuel injection to engine speed. Then, in order to deal with parameter perturbation and load disturbance of the marine diesel engine, a finite-time convergence active disturbance rejection control (ADRC) is proposed. At the last, simulation experiments are conducted to verify the effectiveness of the proposed controller under the different load disturbances for the 7RT-Flex60C marine diesel engine. The simulation results demonstrate that the proposed control scheme has better control effect and stronger anti-interference ability than the linear ADRC.

Authors: Wei Yi , Zhai Peng , Chen Xiaoyi , He Lei
Published: February 2020

Optical freeform surface components have attracted much attention due to their high degree of design freedom and small size. However, the design and processing difficulty of such components limit its wide application in optics industry. In recent years, diamond turning has been considered an efficient method for processing optical freeform surfaces, but the research on tool path generation of this processing method is not systematic. Progressive addition lens (PAL) is a typical optical freeform surface and is widely used to correct people’s vision problems. Firstly, this paper introduces a method of designing PAL. Then, an optimized tool path generation method for diamond turning of the optical freeform surface is proposed, the equal angle method is used to select the discrete points, and a tool nose radius compensation method suitable for both slow slide servo (SSS) and fast tool servo (FTS) is adopted. Finally, the turning experiment is carried out with a single point diamond lathe, and a PAL surface with a roughness of 0.087 μm was obtained. The power and astigmatism distributions were measured using a Rotlex freeform verifier to verify the rationality of the optical design.
A Predictor-Corrector Finite Element Method for Time-Harmonic Maxwell’s Equations in Polygonal Domains
Authors: Nkemzi Boniface , Nkeck Jake Léonard
Published: February 2020

The overall efficiency and accuracy of standard finite element methods may be severely reduced if the solution of the boundary value problem entails singularities. In the particular case of time-harmonic Maxwell’s equations in nonconvex polygonal domains Ω, H1-conforming nodal finite element methods may even fail to converge to the physical solution. In this paper, we present a new nodal finite element adaptation for solving time-harmonic Maxwell’s equations with perfectly conducting electric boundary condition in general polygonal domains. The originality of the present algorithm lies in the use of explicit extraction formulas for the coefficients of the singularities to define an iterative procedure for the improvement of the finite element solutions. A priori error estimates in the energy norm and in the L2 norm show that the new algorithm exhibits the same convergence properties as it is known for problems with regular solutions in the Sobolev space H2Ω2 in convex and nonconvex domains without the use of graded mesh refinements or any other modification of the bilinear form or the finite element spaces. Numerical experiments that validate the theoretical results are presented.
A Total Fractional-Order Variation Regularized Reconstruction Method for CT
Authors: Chen Yun , Guo Baoyu , Lu Yao
Published: February 2020

The total variation (TV) regularized reconstruction methods for computed tomography (CT) may lead to staircase effects in the reconstructed images because of using the TV regularization. This paper develops a total fractional-order variation regularized CT reconstruction method, aiming at overcoming the weakness of the reconstruction methods based on the TV. Specifically, we propose an optimization model for CT reconstruction, including a fidelity term, a regularization term, and a constraint term. Here, the regularization is a total fractional-order variation arising from the fractional derivative of the underlying solution. To address the nondifferentiability of the resulting model, we introduce a fixed-point characterization for its solution through the proximity operators of the nondifferentiable functions. Based on the characterization, we further develop a fixed-point iterative scheme to solve the resulting model and provide convergence analysis of the developed scheme. Numerical experiments are presented to demonstrate that the developed method outperforms the TV regularized reconstruction method in terms of suppressing noise for CT reconstruction.

Authors: Xu Wenting , Tang Mengyu , Wang Jiahui , Wang Lihong
Published: February 2020

Background. Polycystic ovary syndrome (PCOS) is the most common female endocrine disease. Cangfu Daotan Decoction (CDD) can effectively relieve the clinical symptoms of PCOS patients. Methods. To explore the active ingredients and related pathways of CDD for treating PCOS, a network pharmacology‐based analysis was carried out. The active ingredients of CDD and their potential targets were obtained from the TCM system pharmacology analysis platform. The obtained PCOS‐related genes from OMIM and GeneCards were imported to establish protein‐protein interaction networks in STRING. Finally, GO analysis and significant pathway analysis were conducted with the RStudio (Bioconductor) database. Results. A total of 111 active compounds were obtained from 1433 ingredients present in the CDD, related to 118 protein targets. In addition, 736 genes were found to be closely related to PCOS, of which 44 overlapped with CDD and were thus considered therapeutically relevant. Pathway enrichment analysis identified the AGE‐RAGE signalling pathway in diabetic complications, endocrine resistance, the IL‐17 signalling pathway, the prolactin signalling pathway, and the HIF‐1 signalling pathway. Moreover, PI3K‐Akt, insulin resistance, Toll‐like receptor, MAPK, and AGE‐RAGE were related to PCOS and treatment. Conclusions. CDD can effectively improve the symptoms of PCOS, and our network pharmacological analysis lays the foundation for future clinical research.
Fractional K-BKZ Numerical Model of the Start-Up Flow for a Viscoelastic Shock Absorber
Authors: Mao Baoquan , Wang Zhiqian , Yang Yuying , Zhu Rui , Zhao Qijin , Zheng Bowen
Published: February 2020

This paper has proposed a fractional K-BKZ numerical model by adopting the framework of the classical K-BKZ model and the relaxation modulus of the fractional Maxwell model with quasiproperties to study the start-up flow of a viscoelastic shock absorber. The start-up flows in both the orifice and the gap of a shock absorber were simplified to unidirectional accelerated flows in a pipe and between two parallel plates where one plate is accelerating and the other is at rest. The fractional K-BKZ numerical model was then developed using the finite difference method with real-world initial and boundary conditions. Numerical simulation was then performed, and the results were validated through laboratory testing, based on a comparison of the maximum fluid level and the contact angle. The proposed fractional K-BKZ numerical model successfully simulated the characteristics of the viscoelastic material passing through the orifice or the gap of a shock absorber, as demonstrated by accurately capturing the change of the shape of the flow. This fractional K-BKZ numerical model provided better accuracy for the fluid’s viscoelasticity and can be used for shock absorber design.
Research on China’s Ecological Welfare Performance Evaluation and Improvement Path from the Perspective of High-Quality Development
Authors: Wang Rong , Feng Yue
Published: February 2020

Based on the data of China’s ecological environment from 2006 to 2018, the paper uses the super-efficiency DEA and Malmquist index methods to evaluate China’s ecological welfare performance from a static and dynamic perspective. Based on this, the Theil index is used to analyze the group’s ecological welfare performance. The internal and intergroup differences show that, from the static evaluation results, China’s ecological welfare performance is in a situation of “high in the east, low in the west, and average in the central region.” There is not much difference between the eastern and central regions, while the ecological welfare performance in the western region is low. From the results of dynamic evaluation, the overall level of regional ecological welfare performance in China has improved in recent years, and the average Malmquist index has exceeded 1, indicating that the growth pattern of ecological welfare performance has shifted to high quality, but the degree of increase in each region is different. There is still much room for improvement in ecological welfare performance; from the perspective of intragroup and intergroup differences, the intragroup differences and intergroup differences in the three major regions have generally maintained a continuous downward trend, and the contribution of the differences in ecowelfare performance between group rate has a clear advantage. Finally, corresponding suggestions are put forward based on the empirical results of the paper.
An Approach for Reconstruction of Realistic Economic Data Based on Frequency Characteristics between IMFs
Authors: Du Hao , Gong Hao , Han Suyue , Zheng Peng , Liu Bin , Zhou Zhongli
Published: February 2020

Reconstruction of realistic economic data often causes social economists to analyze the underlying driving factors in time-series data or to study volatility. The intrinsic complexity of time-series data interests and attracts social economists. This paper proposes the bilateral permutation entropy (BPE) index method to solve the problem based on partly ensemble empirical mode decomposition (PEEMD), which was proposed as a novel data analysis method for nonlinear and nonstationary time series compared with the T-test method. First, PEEMD is extended to the case of gold price analysis in this paper for decomposition into several independent intrinsic mode functions (IMFs), from high to low frequency. Second, IMFs comprise three parts, including a high-frequency part, low-frequency part, and the whole trend based on a fine-to-coarse reconstruction by the BPE index method and the T-test method. Then, this paper conducts a correlation analysis on the basis of the reconstructed data and the related affected macroeconomic factors, including global gold production, world crude oil prices, and world inflation. Finally, the BPE index method is evidently a vitally significant technique for time-series data analysis in terms of reconstructed IMFs to obtain realistic data.
Early Recognition and Treatment of Malignant Hyperthermia in Pediatric Patient during Bronchoscopy
Authors: Lapisatepun Warangkana , Arkarattanakul Supawan
Published: February 2020

Malignant hyperthermia is a rare pharmacogenetic disorder triggered by depolarizing muscle relaxant and potent volatile anesthetic agents. An MH crisis is an emergency and life-threatening event requiring early recognition and prompt management. Dantrolene is the specific antagonist of MH. The authors report the case of a 9-year-old boy who underwent an emergency bronchoscopy to remove a foreign body and developed masseter rigidity after succinylcholine and sevoflurane exposure. The anesthesia team diagnosed an MH event, and the event was managed immediately with supportive treatment, dantrolene, being administered within 10 minutes. The patient survived and had a good outcome without any complications. We suggest that it is essential for anesthesia providers to recognize the need for intraoperative vigilance, prompt recognition, and treatment, and dantrolene sodium should be readily available in every hospital.

Authors: Ali Ahmed Mohammed , Aziz Asmaa Salah
Published: February 2020

For any two distinct vertices u and  v in a connected graph G, let lPu,v=lP be the length of u−v path P and the D–distance between u and v of G is defined as: dDu,v=minplP+∑∀y∈VPdeg y, where the minimum is taken over all u−v paths P and the sum is taken over all vertices of u−v path P. The D-index of G is defined as WDG=1/2∑∀v,u∈VGdDu,v. In this paper, we found a general formula that links the Wiener index with D-index of a regular graph G. Moreover, we obtained different formulas of many special irregular graphs.

Published: February 2020

Settlement simulating in cohesion materials is a crucial issue due to complexity of cohesion soil texture. This research emphasis on the implementation of newly developed machine learning models called hybridized Adaptive Neuro‐Fuzzy Inference System (ANFIS) with Particle Swarm Optimization (PSO) algorithm, Ant Colony optimizer (ACO), Differential Evolution (DE), and Genetic Algorithm (GA) as efficient approaches to predict settlement of shallow foundation over cohesion soil properties. The width of footing (B), pressure of footing (qa), geometry of footing (L/B), count of SPT blow (N), and ratio of footing embedment (Df/B) are considered as predictive variables. Nonhomogeneity and inconsistency of employed dataset is a major concern during prediction modeling. Hence, two different modeling scenarios (i) preprocessed dataset (PP) and (ii) nonprocessed (initial) dataset (NP) were inspected. To assess the accuracy of the applied hybrid models and standalone one, multiple statistical metrics were computed and analyzed over the training and testing phases. Results indicated ANFIS‐PSO model exhibited an accurate and reliable prediction data intelligent and had the highest predictability performance against all employed models. In addition, results demonstrated that data preprocessing is highly essential to be performed prior to building the predictive models. Overall, ANFIS‐PSO model showed a robust machine learning for settlement prediction.

Published: February 2020

The use of reclaimed asphalt pavement is a practice that is adding significant environmental value to road technologies, not only due to the reduction of materials sent to landfill but also because of the mechanical properties of the reclaimed asphalt (RA) that can be reused. This research focuses on the rheological properties of hot and cold bituminous mastics made up as follows: (1) hot mastics mixed with limestone filler (LF) and bitumen, (2) hot mastics, made from bitumen mixed with jet grouting waste (JW), a mixture of water, cement, and soil derived from land consolidation work in underground tunnels, and (3) hot mastics mixed with LF and JW as filler and bitumen. Three different ratios (0.3, 0.4, and 0.5) of filler per unit of neat bitumen (B50/70) were studied. The same number was used for mixing cold mastics, by using an appropriate laboratory protocol designed since the adoption of a cationic bituminous emulsion. A total of 18 mastics were prepared and investigated. The comparison was carried out using the frequency sweep (FS) test, analysing shear modulus G∗, applying the multistress creep and recovery (MSCR) test (40°C and 60°C) as well as the delta ring and ball (ΔR&B) test, focusing on two main issues: (1) the stiffening effect caused by the filler type used for mixing each mastic, and (2) a comparison, in terms of stiffening effects and nonrecoverable creep compliance (Jnr) of hot and cold mastic performance to highlight JW reuse in mastics. The results showed that the best G∗ performance at test temperatures higher than 30°C is given by cold mastic after 28 days of curing time when JW is added to LF and bitumen. The lowest Jnr value was 40°C and 60°C for the same mastic.
Microannulus Formation Mechanism at the Cementing Interface of a Thermal Recovery Well during Cyclic Steam Injection
Authors: Wu JiWei , Wang XueGang , Song Lin , Zhong ShouMing , Yin WenFeng
Published: February 2020

During the thermal recovery of heavy oil when using cyclic steam injection technology, a microannulus tends to form at the cementing interface subjected to high temperature and pressure during steam injection, and large temperature and pressure differences after injection can lead to wellbore integrity failure. In this study, a thermomechanical coupled finite element casing‐cement‐formation model of a thermal recovery wellbore is established. The deformation of the wellbore during both the steam injection stage and the steam shutdown stage is analyzed. The microannulus formation mechanism at the cementing interface of the wellbore is studied. During steam injection, under the large thermomechanical coupling load, the wellbore generates a high stress that leads to elastic‐plastic deformation. In the steam shutdown stage, with the load on the wellbore decreasing, elastic deformation recovers mostly, while plastic deformation continues. If the plastic deformation is large enough, a microannulus will form at the cementing interface. Increasing the elastic moduli of the casing, cement, and the formation can enlarge their plastic deformation during steam injection. The increase of plastic deformation of the cement or formation can enlarge the microannulus of the casing‐cement interface or the cement‐formation interface correspondingly in the steam shutdown stage.
Space-Based Optical Observations on Space Debris via Multipoint of View
Authors: Li Zhao , Wang Yidi , Zheng Wei
Published: February 2020

In this paper, the space debris catalogue in LEO is fulfilled using multipoint of view (MPOV) observations constructed by a spacecraft formation. The dual-point of view (DPOV) observation is employed because it has higher cost-benefit ratio than other MPOV methods, and it required that the target is detectable for multiple optical sensors simultaneously. This condition is matched by designing the orbit of formation and the installation angles of sensors without frequent attitude maneuvers. The design parameters are optimized to maximize the matching degree of observation constraints to improve the coverage performance of the formation, and the equivalent ranging error is taken into account to ensure the orbit determination accuracy. Finally, the system capabilities of different schemes are compared by simulations. For the schemes with the same number of platforms, simulation results show that the initial orbit determination accuracy of the proposed scheme is higher.
Bi-Objective Re-Entrant Hybrid Flow Shop Scheduling considering Energy Consumption Cost under Time-of-Use Electricity Tariffs
Authors: Geng Kaifeng , Ye Chunming , Dai Zhen hua , Liu Li
Published: February 2020

Re-entrant hybrid flow shop scheduling problem (RHFSP) is widely used in industries. However, little attention is paid to energy consumption cost with the raise of green manufacturing concept. This paper proposes an improved multiobjective ant lion optimization (IMOALO) algorithm to solve the RHFSP with the objectives of minimizing the makespan and energy consumption cost under Time-of-Use (TOU) electricity tariffs. A right-shift operation is then used to adjust the starting time of operations by avoiding the period of high electricity price to reduce the energy consumption cost as far as possible. The experimental results show that IMOALO algorithm is superior to multiobjective ant lion optimization (MOALO) algorithm, NSGA-II, and MOPSO in terms of the convergence, dominance, and diversity of nondominated solutions. The proposed model can make enterprises avoid high price period reasonably, transfer power load, and reduce the energy consumption cost effectively. Meanwhile, parameter analysis indicates that the period of TOU electricity tariffs and energy efficiency of machines have great impact on the scheduling results.
Two Cases of Nonsuicidal Self-Injury Comprising Partial Autoamputation of the Apex of the Tongue
Authors: Moriya Takashi , Sato Hitoshi , Takeda Kenichi , Ikezaki Kaori , Katada Ryogo , Shirota Tatsuo
Published: February 2020

The prevalence of nonsuicidal self-injury (NSSI) in adults is lower than that in adolescents and it is more prevalent in patients with psychiatric disorders. Sleep disturbances such as nightmares are associated with NSSI after accounting for depression; thus, persons with major NSSI sometimes present at medical institutions during the night seeking emergency treatment. Gingival tissues comprise the most frequent target of self-injury of the oral cavity using oral hygiene tools. Most NSSI in the oral cavity is minor because such tools are blunt. Major NSSI such as autoamputation of the tongue is rare. We describe two patients who partially autoamputated the apex of their own tongues using edged tools. Case 1 was a 55-year-old female with depression who had defaulted from psychiatric intervention. She had cut off her tongue using a Japanese kitchen knife and presented with the dry, necrotic amputated portion and blood oozing from the remainder of her tongue. We debrided and sutured the remainder of the tongue without reattaching the amputated portion. Her postoperative course was uneventful, and she was free of adverse events such as functional disability and wound infection. Case 2 was a 69-year-old female with schizophrenia who had defaulted from psychiatric intervention and had cut off her tongue using scissors. The amputated portion of the tongue was lost and the remainder, which was oozing blood, was debrided and sutured. She defaulted on a follow-up appointment. Neither of these patients had suicidal intent. The prevalence of NSSI across all age groups has recently increased, and the risk that self-injury will become normalized has become a concern. Thus, dentists as well as oral and maxillofacial surgeons should be aware of the possibility that patients will present with major NSSI requiring emergency treatment.

Authors: Cao Jian , Yan Yuting , Wang Lingyuan , Chen Xihui , Zhang Xuemei , Zhou Gengui
Published: February 2020

The uncertainty caused by emergencies will influence the normal operation of the supply chain. Considering demand disruptions, a closed-loop supply chain consisting of one manufacturer and two competing retailers based on decentralized decision-making is considered. In the supply chain, one retailer recovers end-of-life products while the other does not. Analytic results show that, when the disturbance of demand occurs, the manufacturer and retailers adjust the wholesale price and retail prices of products according to the direction of the market demand disruptions. Under demand disruptions, the retailer who participates in recovering can gain more profits, especially in the case of the positive disruption. Theoretic and pragmatic references for the emergency decision-making of closed-loop supply chain enterprises are provided.

Este artigo ampara-se na investigação teórica acerca da necropolítica neoliberal quando de encontro ao nomadismo. A interpretação da política neoliberal como trabalho para a morte e da soberania como a expressão do direito de matar ganha dimensão material a partir de uma análise sociológica das práticas culturais e transformações das cidades contemporâneas: trata-se de uma breve corpografia (cartografia realizada pelo corpo) dos povos errantes no território da Bahia e da análise de suas conjecturas econômico-sociais quando do advento do bolsonarismo, a fim de desvelar a violência empunhada pelo Estado sobre três atores sociais representantes do nomadismo: o peregrino (romeiro religioso a cidade de Bom Jesus da Lapa, oeste do estado), o originário (comunidade remanescente indígena Ribeirão dos Paneleiros, na cidade de Vitória da Conquista, região sudoeste), e o andarilho (em situação de rua na capital baiana: Salvador).
O Facebook enquanto “verdade seduzida”: um ensaio crítico de sua comunidade global

Published: February 2020

O ensaio tem por objetivo discutir criticamente a rede social Facebook, especificamente a sua intenção de construir uma comunidade comunicacional global. Assim, a partir de uma abordagem teórica multiperspectivística, mobilizando a sociologia comunicacional de Muniz Sodré; as interfaces analíticas dos estudos culturais; a teoria crítica da cultura; e as discussões interdisciplinares da comunicação, analisamos o discurso do fundador e CEO da rede, Mark Zuckerberg, consubstanciado na nota “Building Global Community”, publicada em fevereiro de 2017. Desta forma, esta reflexão incide sobre as questões relativas aos conceitos de cultura e de diversidade cultural, cuja elaboração no Facebook, na verdade, fomenta o surgimento de uma comunidade comunicacional distópica e contrária aos direitos humanos e ao diálogo intercultural.
As narrativas sobre os indígenas brasileiros nos megaeventos mundiais do século XXI
Authors: Malanski Daniel
Published: February 2020

Megaeventos internacionais têm como objetivo transmitir uma narrativa favorável para nações anfitriãs e seu povos. No caso do Brasil, a organização da Copa do Mundo da Fifa 2014 e dos Jogos Olímpicos de Verão de 2016 proporcionou ao país uma poderosa exposição midiática capaz de apresentar novas narrativas de sua história em um período de apenas dois anos. Este artigo descreve como os comitês organizadores dos eventos mencionados representaram os primeiros habitantes do país, os ameríndios, com a seleção de diferentes narrativas construídas ao longo da história intelectual brasileira. Portanto este artigo busca, por meio de um apanhado histórico, expor os movimentos culturais e eventos políticos que culminaram no entendimento que parte da sociedade brasileira – na qual os comitês supracitados estão inseridos – tem sobre os ameríndios e seu papel na construção da nação.
A dimensão pedagógica do Cinema Negro: a imagem de afirmação positiva do íbero-ásio-afro-ameríndio
Authors: Prudente Celso Luiz
Published: February 2020

A imagem do negro é uma questão das relações étnico-raciais. A dimensão pedagógica do cinema negro estabeleceu uma imagem de afirmação positiva da africanidade. O negro brasileiro se constituiu em minoria maiorizada. Na era da informação, própria da Revolução Tecnológica, as relações abstratas da representação são mais importantes que as relações concretas do fato. A imagem se tornou fundamental para o afrodescendente, pois as lutas de classe se projetaram em lutas de imagens. Os nomos estranhos às culturas eurocidentais são vítimas da desarticulação dos seus traços epistêmicos, justificando a colonização europeia. A dimensão pedagógica se construiu na luta ontológica da imagem de horizontalidade do íbero-ásio-afro-ameríndio contra a verticalidade do euro-hétero-macho-autoritário e sua euro-heteronormatividade.

Rapid coronary plaque progression (RPP) is associated with incident cardiovascular events. To date, no method exists for the identification of individuals at risk of RPP at a single point in time. This study integrated coronary computed tomography angiography–determined qualitative and quantitative plaque features within a machine learning (ML) framework to determine its performance for predicting RPP.

Methods and Results

Qualitative and quantitative coronary computed tomography angiography plaque characterization was performed in 1083 patients who underwent serial coronary computed tomography angiography from the PARADIGM (Progression of Atherosclerotic Plaque Determined by Computed Tomographic Angiography Imaging) registry. RPP was defined as an annual progression of percentage atheroma volume ≥1.0%. We employed the following ML models: model 1, clinical variables; model 2, model 1 plus qualitative plaque features; model 3, model 2 plus quantitative plaque features. ML models were compared with the atherosclerotic cardiovascular disease risk score, Duke coronary artery disease score, and a logistic regression statistical model. 224 patients (21%) were identified as RPP. Feature selection in ML identifies that quantitative computed tomography variables were higher‐ranking features, followed by qualitative computed tomography variables and clinical/laboratory variables. ML model 3 exhibited the highest discriminatory performance to identify individuals who would experience RPP when compared with atherosclerotic cardiovascular disease risk score, the other ML models, and the statistical model (area under the receiver operating characteristic curve in ML model 3, 0.83 [95% CI 0.78–0.89], versus atherosclerotic cardiovascular disease risk score, 0.60 [0.52–0.67]; Duke coronary artery disease score, 0.74 [0.68–0.79]; ML model 1, 0.62 [0.55–0.69]; ML model 2, 0.73 [0.67–0.80]; all

Conclusions

Based on a ML framework, quantitative atherosclerosis characterization has been shown to be the most important feature when compared with clinical, laboratory, and qualitative measures in identifying patients at risk of RPP.
Getting Caught: A Collaboration On- and Offstage between Theatre and Anthropology
Authors: Giordano Cristiana , Pierotti Greg
Published: February 2020

How does an ethnographer remain affected by worlds encountered after leaving the field of research? How does a theatrical deviser build theatrical worlds from empirical research that convey affective experience rather than just dramaturgically sound documentary-style narrative? Affect Theatre is a thinking and acting space for exploring these questions.
Aquarium Mermaids: Multiskilled Entrepreneurs in the Creative Economy
Authors: Davis Tracy C. , Strandvad Sara Malou
Published: February 2020

Since 2011, multiskilled “entreployees” have navigated the creative economy and forged employment for themselves in aquariums around the world. These mermaid performers plunge into tanks and portray chimerical “belonging” in the aquatic environment. While mermaid shows can easily be debunked as gimmicky commercial entertainment that exploits female sexuality, performers display exceptional skills and not only instill belief in mermaids in young visitors, but also raise awareness about ecological issues.
The Vagina Is the Third Ear
Authors: Masaoka Miya
Published: February 2020

The vagina resembles the fleshy folds of the ear without the cartilage. Like the Third Eye, the Third Ear connotes a supernatural ability of intuition, perception. Female sexuality is broadened and expanded, as the vagina is reimagined and reclaimed from previous definitions. Performances with vibrating surfaces and internal vaginal microphones sonify and activate the vagina in real time. This sonic reveal of female body parts asserts a political radicality beyond the gallery or concert hall.
Grain Crisis at Prusa
Authors: Oppeneer Thierry V.
Published: February 2020

This contribution examines an assembly speech that was pronounced by Dio of Prusa in the context of a grain crisis (Or. 46) in order to provide new insights into the politics of the Greek polis under Rome. Whereas inscriptions highlight the eagerness and zeal displayed by elite citizens in helping out their fatherlands, this speech points to the existence of tensions and conflict in the resolution of food crises. The oration’s rhetorical strategies oscillate between the expectations of a popular audience and an elite politician’s desire to shape and control those expectations. A rhetorical analysis of these strategies indicates that Prusan politics was grounded in a civic discourse that provided the people with the ideological means to assert real influence in the local political process. The 46th oration thus attests to the persistence of a democratic tradition of popular political participation in a time when elites had become increasingly powerful.
Fit for a Dog? Food Sharing and the Medieval Human/Animal Divide
Authors: Langdon Alison
Published: February 2020

Medieval unease with human animality manifests itself strongly in attitudes toward and proscriptions concerning food sharing. This is particularly true with dogs, the nonhuman animals with whom humans most intimately share both the procurement and consumption of food, and who are routinely figured as embodying many of the best and worst characteristics associated with humans. Through a range of late medieval texts, this paper will probe the precarious boundary between human and nonhuman animals in the medieval imagination by considering the portrait of Chaucer’s Prioress and her lapdogs in The Canterbury Tales; depictions of dogs in the hunt in medieval romance; and the strange tale of Sir Gowther, whose penance is to eat only what he receives from the mouth of a dog. Rather than supporting claims for an essential difference between human and nonhuman animal, such examples further emphasize the fluidity of the two categories.
Effective Justice
Authors: Crisp Roger , Pummer Theron
Published: February 2020

Effective Altruism is a social movement which encourages people to do as much good as they can when helping others, given limited money, time, effort, and other resources. This paper first identifies a minimal philosophical view that underpins this movement, and then argues that there is an analogous minimal philosophical view which might underpin Effective Justice, a possible social movement that would encourage promoting justice most effectively, given limited resources. The latter minimal view reflects an insight about justice, and our non-diminishing moral reason to promote more of it, that surprisingly has gone largely unnoticed and undiscussed. The Effective Altruism movement has led many to reconsider how best to help others, but relatively little attention has been paid to the differences in degrees of cost-effectiveness of activities designed to decrease injustice. This paper therefore not only furthers philosophical understanding of justice, but has potentially major practical implications.
Finite verb forms in Beja (Cushitic): Labels vs functions, a historical perspective
Authors: Vanhove Martine
Published: February 2020

The historical overview of the indicative finite verb forms of Beja (Cushitic) shows that several reasons may have induced the choice of labels by the linguists who worked on it since the second half of the 19th century. Linguists of Beja can be divided into two groups: descriptivists and comparatists. The former mostly adapted existing terminologies from various linguistic traditions, rarely explicitly, the latter mostly recycled them. Apart from this partition, several factors behind the choice of a label can be inferred, or are sometimes given by the authors. Beyond the lack of in-depth functional and semantic analysis of the verb forms until very recently, there is a clear-cut distinction between temporal and aspectual labels which correlates with the historical development of aspectual theories, and also with the linguistic traditions for Greek, Indo-European and Semitic. But labels are also linked to “national” traditions, in the sense of language areas (corresponding either to the native language of the authors, or to the language in which the grammars were written), namely German, English and French. Grammars written in German are the oldest ones, and their labels conform to the classical philological tradition of their time, even if at times in contradictory ways. In the most recent publication by German-speaking linguists, an aspectual stance is adopted by the authors, but they hesitate between temporal and aspectual labels, a mixture which is also found, to different extent in one French and one Swedish linguists. Descriptions of the three finite verb form by British scholars, and the Swedish typologist Östen Dahl, show competing motivations: the British terminology, the philological tradition, but also the first steps towards a more detailed analysis of the functions of the paradigms based on a theory of aspect. The French linguists on the other hand belong to the most recent layer of specialists of Beja and they were both trained in Semitic languages (for which aspectual analyses predominate) and for aspectual analysis. Nevertheless both of them took up existing labels for one of the forms (the iː-form) from British linguists, from Roper for Morin (“conditional”) and from Appleyard for Vanhove (“aorist”).
La notion linguistique d’agglutination. Son histoire et l’analyse des verbes dans les langues Boro-Garo
Authors: Jacquesson François
Published: February 2020

We first examine the concept of agglutination, as it developed in modern linguistics, and tentatively explore its basic tenets. With this purpose, we (1) start from the way Abel Hovelacque first used the word in French, (2) farther in the past find the concept in Schlegel’s writings, then follow it down to Schleicher, (3) describe how the term is now used in Analytic Linguistics, with examples from authors who described the Boro-Garo languages (Tibeto-Burmese, North-East India). We conclude (4) with ideas about the various shades of the concept as far as history is concerned, and linguistic history in particular.
The Bloomfieldian Heritage in Algonquian Linguistics: The Verbal Complex in Innu
Authors: Lambert-Brétière Renée
Published: February 2020

Innu, like other Algonquian languages, has complex verbal morphology, and morphemes are often not easily segmentable. Much of the terminology used in Algonquian linguistics was influenced by early Algonquianists, especially Leonard Bloomfield, and morphemes are described in structural terms: Innu verb stems consist of at least two morphemes, an INITIAL and a FINAL. They may also contain a MEDIAL. Following the Bloomfieldian tradition, a distinction was later proposed between PRIMARY derivation for the derivation of a verb stem, and SECONDARY derivation for morphemes that attach to a verb stem to form a new verb. In this article, I shall explain what the verbal complex in Innu is, describe its component morphemes, and discuss the impact of the Bloomfieldian heritage on the comparative use of data from Algonquian languages and more specifically of Innu.
