Authors: Cheng Lanzi , Zhang Rui , Lv Weixin , Shao Luyu , Wang Zheng , Wang Wei
Published: December 2019

Highly efficient, cost-effective and durable electrocatalysts for water splitting are crucial for energy conversion and storage. Transition-metal phosphides have been proven to be efficient catalysts for water splitting. In this paper, surface phosphation of 3D NiCo2O4 nanowires grown on Ni foam (P-NiCo2O4/NF) have been prepared to investigate the effect of surface phosphating on catalyst activity. XRD and XPS results demonstrate that P element has been decorated on the surface of the NiCo2O4 nanowires. The electrochemical results prove that P-NiCo2O4/NF shows better electrochemical performance than pure NiCo2O4/NF as an electrode for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) of water splitting. It achieves a current density of 10[Formula: see text]mA cm2 at an overpotential of 279[Formula: see text]mV and 164[Formula: see text]mV for OER and HER in 1.0[Formula: see text]M KOH electrolyte, respectively. In addition, the P-NiCo2O4/NF[Formula: see text]P-NiCo2O4/NF electrode is constructed by employing P-NiCo2O4/NF as both the anode and cathode, it only requires a low 1.68[Formula: see text]V of cell voltage to reach the current density of 10[Formula: see text]mA cm[Formula: see text]. Notably, P-NiCo2O4/NF[Formula: see text]P-NiCo2O4/NF also exhibits excellent stability for over 30[Formula: see text]h-long. These results indicate that surface phosphation is an effective approach to improve the electrochemical performance of NiCo2O4/NF electrode materials.
Learning-Based Adaptive Management of QoS and Energy for Mobile Robotic Missions
Authors: Ho Dinh-Khanh , Ben Chehida Karim , Miramond Benoit , Auguin Michel
Published: December 2019

Mobile robotic systems are normally confronted with the shortage of on-board resources such as computing capabilities and energy, as well as significantly influenced by the dynamics of surrounding environmental conditions. This context requires adaptive decisions at run-time that react to the dynamic and uncertain operational circumstances for guaranteeing the performance requirements while respecting the other constraints. In this paper, we propose a reinforcement learning (RL)-based approach for Quality of Service QoS and energy-aware autonomous robotic mission manager. The mobile robotic mission manager leverages the idea of (RL) by monitoring actively the state of performance and energy consumption of the mission and then selecting the best mapping parameter configuration by evaluating an accumulative reward feedback balancing between QoS and energy. As a case study, we apply this methodology to an autonomous navigation mission. Our simulation results demonstrate the efficiency of the proposed management framework and provide a promising solution for the real mobile robotic systems.
Eigenvalue rigidity for truncations of random unitary matrices
Authors: Meckes Elizabeth , Stewart Kathryn
Published: December 2019

We consider the empirical eigenvalue distribution of an [Formula: see text] principal submatrix of an [Formula: see text] random unitary matrix distributed according to Haar measure. For [Formula: see text] and [Formula: see text] large with [Formula: see text], the empirical spectral measure is well approximated by a deterministic measure [Formula: see text] supported on the unit disc. In earlier work, we showed that for fixed [Formula: see text] and [Formula: see text], the bounded-Lipschitz distance [Formula: see text] between the empirical spectral measure and the corresponding [Formula: see text] is typically of order [Formula: see text] or smaller. In this paper, we consider eigenvalues on a microscopic scale, proving concentration inequalities for the eigenvalue counting function and for individual bulk eigenvalues.

Published: December 2019

The pursuit of computational efficiency has led to the proliferation of
throughput-oriented
hardware, from GPUs to increasingly wide vector units on commodity processors and accelerators. This hardware is designed to execute data-parallel computations in a vectorized manner efficiently. However, many algorithms are more naturally expressed as divide-and-conquer, recursive,
task-parallel
computations. In the absence of data parallelism, it seems that such algorithms are not well suited to throughput-oriented architectures. This article presents a set of novel code transformations that expose the data parallelism latent in recursive, task-parallel programs. These transformations facilitate straightforward vectorization of task-parallel programs on commodity hardware. We also present scheduling policies that maintain high utilization of vector resources while limiting space usage. Across several task-parallel benchmarks, we demonstrate both efficient vector resource utilization and substantial speedup on chips using Intel’s SSE4.2 vector units, as well as accelerators using Intel’s AVX512 units. We then show through rigorous sampling that, in practice, our vectorization techniques are effective for a much larger class of programs.

Published: December 2019

Deep Neural Networks (DNNs) are now increasingly adopted in a variety of Artificial Intelligence (AI) applications. Meantime, more and more DNNs are moving from cloud to the mobile devices, as emerging AI chips are integrated into mobiles. Therefore, the DNN models can be deployed in the cloud, on the mobile devices, or even mobile-cloud coordinate processing, making it a big challenge to select an optimal deployment strategy under specific objectives.

This article proposes a DNN tuning framework, i.e., DNNTune, that can provide layer-wise behavior analysis across a number of platforms. Using DNNTune, this article further selects 13 representative DNN models, including CNN, LSTM, and MLP, and three mobile devices ranging from low-end to high-end, and two AI accelerator chips to characterize the DNN models on these devices to further assist users finding opportunities for mobile-cloud coordinate computing. Our experimental results demonstrate that DNNTune can find a coordinated deployment achieving up to 1.66× speedup and 15× energy saving comparing with mobile-only and cloud-only deployment.
Compiler-support for Critical Data Persistence in NVM
Authors: Elkhouly Reem , Alshboul Mohammad , Hayashi Akihiro , Solihin Yan , Kimura Keiji
Published: December 2019

Non-volatile Main Memories (NVMs) offer a promising way to preserve data persistence and enable computation recovery in case of failure. While the use of NVMs can significantly reduce the overhead of failure recovery, which is the case with High-Performance Computing (HPC) kernels, rewriting existing programs or writing new applications for NVMs is non-trivial. In this article, we present a compiler-support that automatically inserts complex instructions into kernels to achieve NVM data-persistence based on a simple programmer directive. Unlike checkpointing techniques that store the whole system state, our technique only persists user-designated objects as well as some parameters required for safe recovery such as loop induction variables. Also, our technique can reduce the number of data transfer operations, because our compiler coalesces consecutive memory-persisting operations into a single memory transaction per cache line when possible.

Our compiler-support is implemented in the LLVM tool-chain and introduces the necessary modifications to loop-intensive computational kernels (e.g., TMM, LU, Gauss, and FFT) to force data persistence. The experiments show that our proposed compiler-support outperforms the most recent checkpointing techniques while its performance overheads are insignificant.

Commercial Real Estate as an Asset Class
Authors: Ghent Andra C. , Torous Walter N. , Valkanov Rossen I.
Published: December 2019

We survey the properties of commercial real estate (CRE) as an asset class. We first illustrate its importance relative to the US economy and to other asset classes. We then discuss CRE ownership patterns over time. While the academic literature has emphasized Real Estate Investment Trusts, about two-thirds of the value of CRE is owner occupied. We next study the return properties of CRE indices and discuss what is known about the returns to individual properties. We briefly discuss CRE debt before turning to property derivatives. Finally, we consider how including CRE in a portfolio affects the portfolio's performance.

Published: December 2019

In mouse ileal myocytes, muscarinic receptor-mediated cationic current ( mIcat) occurs mainly through synergism of M2 and M3 subtypes involving Gi/o-type GTP-binding proteins and phospholipase C (PLC). We have further studied the M2/M3 synergistic pathway. Carbachol-induced mIcat was markedly depressed by YM-254890, a Gq/11 protein inhibitor. However, the mIcat was unaffected by heparin, calphostin C, or chelerythrine, suggesting that mIcat activation does not involve signaling molecules downstream of phosphatidylinositol 4,5-bisphosphate (PIP2) breakdown. M2-knockout (KO) mice displayed a reduced mIcat (~10% of wild-type mIcat) because of the lack of M2-Gi/o signaling. The impaired mIcat was insensitive to neuropeptide Y possessing a Gi/o-stimulating activity. M3-KO mice also displayed a reduced mIcat (~6% of wild-type mIcat) because of the lack of M3-Gq/11 signaling, and the mIcat was insensitive to prostaglandin F2α possessing a Gq/11-stimulating activity. These results suggest the importance of Gq/11/PLC-hydrolyzed PIP2 breakdown itself in mIcat activation and also support the idea that the M2/M3 synergistic pathway represents a signaling complex consisting of M2-Gi/o and M3-Gq/11-PLC systems in which both G proteins are special for this pathway but not general in receptor coupling.
A Bibliometric Analysis of the Development of ICD-11 in Medical Informatics
Authors: Chen Donghua , Zhang Runtong , Zhao Hongmei , Feng Jiayi
Published: December 2019

The International Classification of Diseases (ICD), which is used to group and report health conditions and factors, provides a basis for healthcare statistics. The 11th revision of the ICD (ICD-11) released by the World Health Organization provides stakeholders with novel perspectives on solving the complexity of critical problems in medical informatics. This study conducts a bibliometric analysis of research published over the period of 1989–2018 to examine the development of ICD-related research and its trends. First, over 4000 ICD-related papers spanning the 30-year period are retrieved from the Web of Science database. Then, based on the meta data of the selected papers, time trend analysis is performed to examine the development of different ICD revisions. Finally, the keywords and topics of these papers are analyzed and visualized using VOSViewer and CiteSpace. Our findings indicate that ICD-11-related research has grown rapidly in recent years compared with studies on ICD-9 and ICD-10. Moreover, the most popular research directions of ICD-11 include the topics psychiatry, psychology, information science, library science, and behavioral science. In terms of perspectives, information system-related research is more common than big data- and knowledge discovery-related work. However, the popularity of big data- and knowledge discovery-related developments has grown in recent years. The use of ICD-11 facilitates the development of medical informatics from the perspectives of information systems, big data, and knowledge discovery.

Published: December 2019

Attack graph can simulate the possible paths used by attackers to invade the network. By using the attack graph, the administrator can evaluate the security of the network and analyze and predict the behavior of the attacker. Although there are many research studies on attack graph, there is no systematic survey for the related analysis methods. This paper firstly introduces the basic concepts, generation methods, and computing tasks of the attack graph, and then, several kinds of analysis methods of attack graph, namely, graph-based method, Bayesian network-based method, Markov model-based method, cost optimization method, and uncertainty analysis method, are described in detail. Finally, comparative study of the methods and future work are provided. We believe that this work would help the research community to understand the attack graph analysis method systematically.

Authors: Anyiam Oluwaseun , Wallin Elizabeth , Kaplan Felicity , Lawrence Christopher
Published: December 2019

Renal Fanconi syndrome (RFS) is characterised by generalised dysfunction of the proximal renal tubules, resulting in excessive urinary loss of solutes, most notably bicarbonate, and type II (proximal) renal tubular acidosis. It is a rare condition, and literature around its management through pregnancy is limited. We present the management of a 37-year-old woman with RFS secondary to the HNF4A p.R63W mutation, through her third pregnancy. She presented at 28 + 5 weeks with dehydration, low serum bicarbonate, and profound metabolic acidosis. Daily infusions of sodium bicarbonate were necessary, and the requirements increased throughout the pregnancy. She also demonstrated both fasting hypoglycaemia and episodes of postprandial hyperglycaemia which required complex management. Due to concerns around fetal health, an elective caesarean section was performed at 34 weeks, delivering a healthy baby girl. This case highlights the potential complexity of pregnancy in patients with RFS and the need for a multidisciplinary approach to its management.

Published: December 2019

Growth of Cu polyhedral structures with well-defined and controllable shapes faced tremendous synthetic challenges in colloid nanocrystal synthesis in the past few decades. In this article, we report a facile approach for the synthesis of Cu nanocrystals with systematic morphological evolution. Transitional truncated octahedral, edge- and corner-truncated octahedral, all-corner-truncated octahedral, and octahedral structures were obtained in a solution-based reduction reaction by precise tuning reaction time. Four distinct morphologies of nanocrystals have been characterized by SEM technique. The optical properties of these various morphologies of nanocrystals were also investigated, and it indicates that the SPR band shifts red while the shape of nanoparticles evolves from transitional truncated octahedral to octahedral, whose resonant bands are transferred from 590 nm to 620 nm.
polarRLCE: A New Code-Based Cryptosystem Using Polar Codes
Authors: Liu Jingang , Wang Yongge , Yi Zongxiang , Lin Zhiqiang
Published: December 2019

Security challenges brought about by the upcoming 5G era should be taken seriously. Code-based cryptography leverages difficult problems in coding theory and is one of the main techniques enabling cryptographic primitives in the postquantum scenario. In this work, we propose the first efficient secure scheme based on polar codes (i.e., polarRLCE) which is inspired by the RLCE scheme, a candidate for the NIST postquantum cryptography standardization in the first round. In addition to avoiding some weaknesses of the RLCE scheme, we show that, with the proper choice of parameters, using polar codes, it is possible to design an encryption scheme to achieve the intended security level while retaining a reasonably small public key size. In addition, we also present a KEM version of the polarRLCE scheme that can attain a negligible decryption failure rate within the corresponding security parameters. It is shown that our proposal enjoys an apparent advantage to decrease the public key size, especially on the high-security level.
Modeling Investor Behavior Using Machine Learning: Mean‐Reversion and Momentum Trading Strategies
Authors: Silva Thiago Christiano , Tabak Benjamin Miranda , Ferreira Idamar Magalhães
Published: December 2019

We model investor behavior by training machine learning techniques with financial data comprising more than 13,000 investors of a large bank in Brazil over 2016 to 2018. We take high‐frequency data on every sell or buy operation of these investors on a daily basis, allowing us to fully track these investment decisions over time. We then analyze whether these investment changes correlate with the IBOVESPA index. We find that investors decide their investment strategies using recent past price changes. There is some degree of heterogeneity in investment decisions. Overall, we find evidence of mean‐reverting investment strategies. We also find evidence that female investors and higher academic degree have a less pronounced mean‐reverting strategy behavior comparatively to male investors and those with lower academic degree. Finally, this paper provides a general methodological approach to mitigate potential biases arising from ad-hoc design decisions of discarding or introducing variables in empirical econometrics. For that, we use feature selection techniques from machine learning to identify relevant variables in an objective and concise way.

Soft tissue sarcomas (STS) constitute a heterogeneous group of rare solid tumors associated with significant morbidity and mortality. The evaluation and treatment of STS require a multidisciplinary team with extensive experience in the management of these types of tumors. National and international clinical practice guidelines for STS do not always provide answers to a great many situations that specialists have to contend with in their everyday practice. This consensus provides a series of specific recommendations based on available scientific evidence and the experience of a group of experts to assist in decision-making by all the specialists involved in the management of STS.
Is It T3 Thyrotoxicosis? A Case of Falsely Elevated Tri-Iodothyronine (T3) Levels Leading to a Diagnosis of Multiple Myeloma
Authors: Ram Nanik , Furqan Saira , Ahmed Sibtain
Published: December 2019

We are presenting a case of falsely elevated T3 levels in a patient due to interference from monoclonal immunoglobulins. A 56-year-old, clinically euthyroid man referred to the endocrinology clinic of the Aga Khan university, Karachi Pakistan, for possible T3 thyrotoxicosis after thyroid function tests revealed total T3 >12.32 nmol/L (reference range 0.6–2.79), normal TSH, and total T4 level. There was a mismatch in clinical and laboratory parameters and preliminary laboratory results were suggestive of thyroid binding globulin abnormalities. Further evaluation in this context unmasked multiple myeloma. The presence of monoclonal immunoglobulins can lead to assay interference and spurious results. To the best of our knowledge, this is the second case defining the cause of falsely elevated T3 levels, due to assay interferences with binding of T3 only to monoclonal immunoglobulins.

Published: December 2019

Recently, the mobile wireless communication has seen explosive growth in data traffic which might not be supported by the current Fourth Generation (4G) networks. The Fifth Generation (5G) networks will overcome this challenge by exploiting a higher spectrum available in millimeter-wave (mmwave) band to improve network throughput. The integration of the millimeter-wave communication with device-to-device communication can be an enabling 5G scheme in providing bandwidth-intensive proximity-based services such as video sharing, live streaming of data, and socially aware networking. Furthermore, the current cellular network traffic can also be offloaded by the D2D user devices thereby reducing loading at Base Stations (BSs), which would then increase the system capacity. However, the mmwave D2D communication is associated with numerous challenges, which include signal blockages, user mobility, high-computational complexity resource allocation algorithms, and increase in interuser interference for dense D2D user scenario. The paper presents review of existing channel and power allocation approaches and mathematical resource optimization solution techniques. In addition, the paper discusses the challenges hindering the realization of an effective allocation scheme in mmwave D2D communication and gives open research issues for further study.

Authors: Veloz Alejandro , Weinstein Alejandro , Pszczolkowski Stefan , Hernández-García Luis , Olivares Rodrigo , Muñoz Roberto , Taramasco Carla
Published: December 2019

Brain network analysis using functional magnetic resonance imaging (fMRI) is a widely used technique. The first step of brain network analysis in fMRI is to detect regions of interest (ROIs). The signals from these ROIs are then used to evaluate neural networks and quantify neuronal dynamics. The two main methods to identify ROIs are based on brain atlas registration and clustering. This work proposes a bioinspired method that combines both paradigms. The method, dubbed HAnt, consists of an anatomical clustering of the signal followed by an ant clustering step. The method is evaluated empirically in both in silico and in vivo experiments. The results show a significantly better performance of the proposed approach compared to other brain parcellations obtained using purely clustering-based strategies or atlas-based parcellations.

Published: December 2019

Otomycosis is one of the relatively common diseases in the world which is caused by different fungi especially saprophytes. Concerning the relapse of this disease in a number of individuals, the present study was performed to evaluate the inhibitory effect of clotrimazole drop in the relapse of otomycosis. Clinical samples were taken by an ENT specialist from patients suspicious of having otomycosis. A part of these samples were stained, and others were cultured. The diagnosis of otomycosis was made on the basis of the recognizable and characteristic appearance of fungal hyphae or mycelium and fruiting bodies and/or conidiophores under microscopic examination. Patients with suspected otomycosis are not at risk of recurrence after treatment with clotrimazole drops. Out of the 161 individuals in whom definite diagnosis of otomycosis was made, the most affected individuals were, in the age range of 40–49 years, women, urban citizens, and housewives. Pruritus and diminished hearing were the main complaints of the patients.Aspergillus nigerandA.flavusas well asCandida albicanswere the main causes of the disease. The relapse of disease was observed in only five patients (3.1%), whereA. nigerwas the main fungus. Most relapses were observed in women and in those with diminished hearing, manipulating the ears, ulcers in the canal, and tympanum. Our results suggested that usage of clotrimazole can be effective in reducing the relapse of otomycosis, and concerning the high cost of treating otomycosis while the low cost of using clotrimazole, usage of this drop is recommended to reduce the relapse of otomycosis.

Published: December 2019

In the recent years, olivine LiFePO4 has been considered as a prospective cathode material for lithium-ion batteries. However, low conductivity is an obstacle to the commercialization of LiFePO4; doping the transition metal such as Mn and Ni is one of the solutions for this issue. This work aimed to synthesize the Mn-doped olivines LiMnxFe1−xPO4 at low content of Mn (x = 0.1, 0.2) via the hydrothermal route followed by pyrolyzed carbon coating. The synthesized olivines were well crystallized in olivine structure, with larger lattice parameters compared with LiFePO4. The EXD and TGA results confirmed the coated carbon of 4.14% for LiMn0.1Fe0.9PO4 and 6.86% for LiMn0.2Fe0.8PO4. Both of Mn-doped olivines showed higher diffusion coefficients of Li+ intercalation than those of LiFePO4 that led a good performance in the cycling test. LiMn0.2Fe0.8PO4 exhibited a higher specific capacity (160 mAh/g) than LiMn0.1Fe0.9PO4 (155 mAh/g), and the Mn content is beneficial for the cycling performance as well as ionic conductivity.
Experiment Investigation and Numerical Simulation of Snowdrift on a Typical Large‐Span Retractable Roof
Authors: Cao Zhenggang , Liu Mengmeng , Wu Pengcheng
Published: December 2019

Retractable roofs are commonly used in designing large‐span stadiums because of their versatility. However, retractable roofs are subject to sudden changes in shape, and thus, factors in addition to those considered for conventional roofs need to be taken into account. In particular, retractable roofs are considerably more sensitive to snow loads because their shapes are complex, and snowdrift on roofs may lead to difficulties for the operating of retractable roofs. To investigate the distribution of snow on retractable roofs, this study proposes a method based on a numerical simulation of snowdrift obtained using the Euler–Euler method in multiphase flow theory. This numerical model employs a mixture model by using the commercial computational fluid dynamics (CFD) software FLUENT. A suitable turbulence model is selected for the simulation through verification against two‐dimensional (2D) data obtained from field measurements reported in previous studies. However, the snow load on retractable roofs cannot be determined by a 2D distribution easily. The accuracy of predicting the overall distribution of snow load on roofs was verified by experiments conducted on a horizontally retractable roof. The results show that a nonuniform snow distribution on such roofs is distinct and should be considered.

Published: December 2019

Background. Carnosinase-1 (CN-1) can be detected in 24 h urine of healthy individuals and patients with type 2 diabetes (T2DM). We aimed to assess whether urinary CN-1 is also reliably measured in spot urine and investigated its association with renal function and the albumin/creatinine ratio (ACR). We also assessed associations between theCNDP1(CTG)ngenotype and CN-1 concentrations in serum and urine.Methods. Patients with T2DM (n=85) and nondiabetic patients with chronic kidney disease (CKD) (n=26) stratified by albuminuria (ACR≤300 mg/gorACR>300 mg/g) recruited from the nephrology clinic and healthy subjects (n=24) were studied.Results. Urinary CN-1 was more frequently detected and displayed higher concentrations in patients withACR>300 mg/gas compared to those withACR≤300 mg/girrespective of the baseline disease (T2DM: 554 ng/ml [IQR 212-934 ng/ml] vs. 31 ng/ml [IQR 31-63 ng/ml] (p<0.0001) and nondiabetic CKD: 197 ng/ml [IQR 112-739] vs. 31 ng/ml [IQR 31-226 ng/ml] (p=0.015)). A positive correlation between urinary CN-1 and ACR was found (r=0.68,p<0.0001). Multivariate linear regression analysis revealed that ACR and serum CN-1 concentrations but not eGFR or the CNDP1 genotype are independent predictors of urinary CN-1, explaining 47% of variation of urinary CN-1 concentrations (R2=0.47,p<0.0001).Conclusion. These results confirm and extend previous findings on urinary CN-1 concentrations, suggesting that assessment of CN-1 in spot urine is as reliable as in 24 h urine and may indicate that urinary CN-1 in macroalbuminuric patients is primarily serum-derived and not locally produced.

Published: December 2019

The main purpose of the present study was to assess the effect of soluble and insoluble fiber on colonic bacteria and intestinal barrier function in a piglet model. A total of 24 piglets (25 ± 1 d old; 7.50 ± 0.31 kg) were randomly allotted to 4 treatments: basal diet (control, CON), 1% insoluble dietary fiber (IDF) diet, 1% soluble dietary fiber (SDF) diet, and 0.5% insoluble fiber + 0.5% soluble dietary fiber (MDF) diet. The trial lasted 28 days. SDF-fed piglets showed a higher P<0.05 bacterial a-diversity (observed_species, chao1, and ACE) and a higher relative abundance of Proteobacteria and Actinobacteria, Solobacterium, Succinivibrio, Blautia, and Atopobium in colonic digesta than CON, IDF, and MDF groups P<0.05. At the same time, Bacteroidetes, Euryarchaeota, Phascolarctobacterium, Coprococcus_1, and Prevotella_1 were significantly increased in the IDF group when compared with CON, SDF, and MDF groups P<0.05. Furthermore, Bacteroidetes and Enterobacteriaceae, Selenomonas, Phascolarctobacterium, and AlloprevotellaP<0.05 were significantly higher in the MDF group than those in the other three groups P<0.05. SDF diet increased the concentrations of short-chain fatty acid (SCFA) in colonic digesta P<0.05 when compared with the CON group and enhanced weight index of the colon P<0.05 than the CON and IDF groups. Furthermore, compared with the CON group, SDF, IDF, and MDF diets all upregulated the mRNA expressions of claudin-1 (CLDN-1) in colonic mucosa P<0.05, SDF and IDF diets upregulated the mRNA expressions of mucin 2 (MUC2) P<0.05, SDF diet increased mRNA expressions of zonula occludens 1 (ZO-1) and occludin (OCLN), while the IDF group enhanced the secretory immunoglobulin A (sIgA) concentrations P<0.05, respectively. IDF and MDF diets decreased expressions of TNF-αP<0.05. We concluded that the influence of soluble fiber on colonic microbiota was more extensive than that of insoluble fiber. Moreover, soluble fiber could more effectively improve colonic barrier function by upregulating gene expressions of the gut barrier.
High Dynamic Range Imaging Based on Bidirectional Structural Similarities and Weighted Low-Rank Matrix Completion
Authors: Yu Mali , Zhang Hai
Published: December 2019

High dynamic range (HDR) imaging, aiming to increase the dynamic range of an image by merging multiexposure images, has attracted much attention. Ghosts are often observed in a resultant image, due to camera motion and object motion in the scene. Low-rank matrix completion (LRMC) provides an effective tool to remove ghosts. However, user specification of the included or excluded regions is required. In this paper, we propose a novel HDR imaging method based on bidirectional structural similarities and weighted low-rank matrix completion. In our method, we first propose the bidirectional structural similarities containing forward-projection structural similarity (FPSS) and backward-projection structural similarity (BPSS) to divide each image into four groups: motion region, saturated region in the source image, saturated region in the reference image, and static and unsaturated regions. Then, the weight maps and the motion maps constructed based on FPSS and BPSS are introduced in the weighted LRMC model to reconstruct the background irradiance maps. Experiments are conducted on several challenging image sets with complex scene, and the results show that the proposed method outperforms three current state-of-the-art methods and Photoshop cs6 and is robust to the reference image.

This paper studies of the use of nanocrystalline cerium dioxide with artificially formed bone tissue defects. The results of morphometry confirmed the antialterative effect in the early stages of the reparative process of damaged bone tissue. When using calcium hydroxide with nanodispersed cerium dioxide, the nature of osteogenesis should be characterized as activated. In case of damage to the dentin of the roots of the teeth, dentinogenesis in presence of CeO2 occurs with the formation of a combined dentin and bone regenerates. Little or no studies of dentinogenesis in presence of CeO2 were performed by other researchers.
Improvement of Different Types of Environmental Regulations on Total Factor Productivity: A Threshold Effect Analysis
Authors: Lei Xubin , Wu Shusheng
Published: December 2019

Based on the distinction of different types of environmental regulations, this paper attempts to test the threshold effect of environmental regulation on the total factor productivity (TFP) by employing a panel threshold model and a province-level panel data set during 2006–2016. Research results show that the influence of command-and-control and market incentive environmental regulation on the total factor productivity has a single threshold conversion characteristic of foreign direct investment (FDI) and financial scale, but the impact behavior and influence degree around the threshold are inconsistent. The effect of voluntary conscious environmental regulation on the total factor productivity has a single threshold conversion feature of human capital, and moderately enhanced intensity of environmental regulation is conducive to promoting the total factor productivity after crossing the threshold. Finally, in order to enhance the regional total factor productivity, relevant policy recommendations are proposed.
Karl Marx - 200 anos
Authors: Souza Rafael Bellan Rodrigues de
Published: December 2019

Com a efeméride das comemorações de duzentos anos do nascimento de Karl Marx, o texto apresenta as quatro fases de sua trajetória enquanto jornalista e debate quais características desta práxis noticiosa podem ser relevantes para uma teoria da prática jornalística contemporânea. Na dialética da continuidade/descontinuidade, este percurso históricobiográfico desenha o perfil do jornalista Marx e revela fatores desta produção que podem ser “repetidos” pelos jornalistas atuais, entre eles, o jornalismo como um mapeamento do território em que as ações humanas podem se objetificar e a fidelidade à exatidão dos acontecimentos, vistos em sua concretude.
Novas tecnologias da informação, escalabilidade e métodos quantitativos e qualitativos nas ciências humanas
Authors: Hooper Silvana Seabra
Published: December 2019

O trabalho examina os pressupostos que orientaram a oposição entre os métodos quantitativos e qualitativos nas ciências humanas e sociais, tratando com destaque o aspecto da escalabilidade como problema epistemológico. Trata-se de retomar alguns pontos deste debate em face das novas tecnologias da informação (NTIs), focando no impacto da grande produção de dados. Compreendendo o método como lógica de investigação, a proposta retoma as discussões de Lev Manovich e Bruno Latour como referência para uma releitura da dicotomia entre os métodos quantitativos e qualitativos nas ciências humanas e sociais.
Celebridade
Authors: Simões Paula Guimarães
Published: December 2019

O objetivo deste texto é discutir a possibilidade de refletir sobre as celebridades como um dispositivo interacional crítico. Partimos da ideia de que os sujeitos célebres podem ser pensados como sujeitos políticos que atuam no contexto social, revelando valores de uma sociedade e seus problemas públicos. A análise se volta para a postura assumida por Fernanda Lima no programa Amor & Sexo, destacando eixos temáticos a partir dos quais podemos apreender os posicionamentos desta celebridade: machismo e misoginia, racismo, LGBTfobia. A análise mostra como a apresentadora se constitui como um dispositivo interacional crítico e pode atuar no fomento a lutas emancipatórias e na reconstrução de gramáticas morais capazes de atuar na promoção da justiça.
Limites do discurso identitário na disputa eleitoral
Authors: Sena Ercio
Published: December 2019

Com o esvaziamento da luta pelo socialismo e a ascensão do neoliberalismo, o campo da esquerda progressista tem sido criticado por tomar a questão identitária como principal motor das lutas sociais. A proposta deste trabalho é identificar e analisar o debate sobre as lutas por reconhecimento identitário na campanha eleitoral de 2018. Serão consideradas as polarizações sobre o tema entre os dois partidos localizados à esquerda do espectro político – PT e PSOL – em relação à campanha majoritária do campo localizado à direita, representada pelo PSL. A partir de suas posições em relação ao tema, explicitadas em uma rede social, pretende-se observar e problematizar os limites desses embates discursivos.
Imaginários de poder e redes midiáticas
Authors: Leão Lucia , Lopes Vanessa , Nunes Mirian Aparecida Meliani , Santos Bernardo Queiroz de Siqueira
Published: December 2019

No campo da pesquisa em comunicação, especificamente no âmbito dos estudos do imaginário, observamos o surgimento de discussões que problematizam temas como arte, iconoclasmo, imagem e poder. Neste cenário, o artigo tem como objetivo desenvolver um estudo transversal sobre os imaginários de poder nas redes midiáticas. Através de mapeamentos das imagens e discursos presentes nas redes do Creative Time Summit, o artigo propõe relações com projetos brasileiros, baseando-se no conceito de imaginário de Durand e adotando como metodologia de análise a cartografia dos processos de comunicação e compartilhamento do imaginário desenvolvida por Leão. Nosso argumento é que as guerras das imagens, a criação de imagens nas comunidades, a compreensão processual e a formulação de pactos que compreendem as relações entre natureza e cultura configuram eixos de análise nas redes midiáticas capazes de revelar as complexas tramas dos imaginários do poder de nossa época.
A crítica da cobertura jornalística sobre minorias a partir das colunas de ombudsman
Authors: Azeredo Diana De
Published: December 2019

Com base nos conceitos de crítica, reconhecimento e minorias problematizados, respectivamente, em pesquisas de Soares e Silva (2016), Serelle e Sena (2018) e Honneth (2009), este estudo tem como objeto de análise a crítica da cobertura jornalística sobre minorias a partir das colunas de ombudsman do jornal Folha de S.Paulo. Trabalhou-se com 41 textos que fazem a crítica da cobertura do jornal sobre a demanda de indígenas, negros, mulheres e integrantes da comunidade LGBTI+. O objetivo é verificar como o exercício autocrítico se dispõe a debater publicamente esta questão, examinando preconceitos e limitações do próprio jornalismo.
Possibilidades políticas da crítica em perspectiva teórica
Authors: Silva Gislene , Soares Rosana De Lima
Published: December 2019

Este estudo discute possibilidades políticas da crítica em face de diferentes perspectivas teóricas, priorizando, neste momento, contribuições da teoria crítica e dos estudos culturais para se fazer a crítica de mídia. Trabalhamos com a necessidade de se privilegiar objetos concretos em circulação no ambiente midiático e de se considerar também os sistemas de produção e recepção em que as obras se inserem. O objetivo, ao levar em conta a diversidade de objetos midiáticos e a variedade de modos de se fazer a crítica de mídia, é debater a conexão entre as perspectivas da teoria crítica e dos estudos culturais no campo da crítica de mídia, especialmente em cenários fortemente marcados por embates políticos e ideológicos.
A passagem do dois ao zero
Authors: Caux Luiz Philipe De , Catalani Felipe
Published: December 2019

Buscamos explorar os desdobramentos da intuição básica de Roberto Schwarz em seu ensaio “As ideias fora do lugar” na obra do filósofo Paulo Arantes. O ponto de vista da periferia do capitalismo (que supera a si mesmo enquanto ponto de vista) não apenas fornece uma visada privilegiada para a compreensão do funcionamento ideológico das sociedades que se desenvolvem à margem do centro orgânico do capital, como também revela a verdade do próprio centro. Esse modelo de crítica se desdobra nos estudos de Arantes sobre a ideologia e em sua tese sobre a periferização do centro no momento do colapso. Investigamos assim se os pressupostos materiais e categoriais daquilo que dava sentido a “Ideias fora do lugar” persistem no instante em que a formação nacional se apresenta como terminada.
Usos do reconhecimento em Roberto Schwarz
Authors: Souza Luiz Gustavo Da Cunha de
Published: December 2019

Em “As ideias fora do lugar”, Roberto Schwarz usa a ideia de reconhecimento em passagens definidoras do texto, mas o conceito nunca recebe um tratamento formal e acabado. Curiosamente, por vezes o emprego se aproxima daquele feito por Axel Honneth. O artigo propõe, então, uma aproximação entre os usos do reconhecimento em Schwarz e Honneth. Para isso, são considerados, em primeiro lugar, usos que Schwarz faz dessa categoria também em outros textos. A seguir, é buscada uma aproximação com o uso recente dado por Honneth à categoria. Por fim, retomando a ênfase na sociedade brasileira, é sugerida uma leitura do conceito de reconhecimento como categoria analítica da sociedade brasileira, devido à sua capacidade de articular certas continuidades sociais próprias à estrutura de arbítrio e dominação de classe no país.
De modernidades periféricas
Authors: García Mónica González
Published: December 2019

Neste artigo utilizo “As ideias fora do lugar”, de Roberto Schwarz, para estudar a sobrevivência da feudalidade e o favor, herdados do colonialismo ibérico, na “Belle Époque” chilena. No período, as desigualdades sociais adquiriram proporções hipertróficas pelo capital que as elites locais receberam da sua incursão na mineração do carvão e na exploração do salitre – a última como resultado da Guerra do Pacífico (1879-1883). Examino as discrepâncias da modernidade periférica chilena do fim do século XIX e começo do XX em três obras “bellepoquistas”: o conto “El rey burgués” (1888), de Rubén Darío, o filme Julio comienza en Julio (1979), com roteiro de Silvio Caiozzi e Gustavo Frías, e a coleção de contos Sub terra (1904), de Baldomero Lillo.
Materialismo corticeiro
Authors: Campos Filho Lindberg
Published: December 2019

Este é um breve exercício de leitura do romance emblemático do naturalismo brasileiro O cortiço (1890) de Aluísio Azevedo, levando em consideração a  crítica produzida por Antonio Candido em “De cortiço a cortiço” (1974; 1991), ao mesmo tempo que levanta a hipótese de que alguns dos métodos de construção dessa narrativa podem ser lidos, em certa medida, como antecipações, ora mais ora menos conscientes, dos paradigmas de determinação social que guiariam a crítica cultural materialista ao longo do século seguinte.

A obra de Jean-Baptiste Debret como fonte histórica para os estudos dos trajes usados no Brasil no início do século XIX
Authors: Araújo Marli Gomes de , Marcicano João Paulo Pereira , Held Maria Sílvia Barros de
Published: December 2019

O artigo apresenta uma visão da moda usada no Brasil no início do século XIX à luz da obra do pintor francês Jean-Baptiste Debret. Sua obra constitui um corpus iconográfico com litografias feitas a partir de suas aquarelas e pranchas que comporiam os fascículos de Viagem pitoresca e histórica ao Brasil. Os trajes retratados por Debret foram analisados sob o olhar de historiadores da moda, concluindo-se que a moda usada no Brasil no período joanino e no Brasil de Pedro I seguiu as tendências europeias da época, o estilo Império e o estilo Romântico.
Recreação e vida ao ar livre em parques infantis de São Paulo na coleção de desenhos de Mário de Andrade
Authors: Wiggers Ingrid Dittrich , Soares Carmen Lucia
Published: December 2019

O Projeto Parques Infantis, implantado na década de 1930, propôs a criação de instituições que configurassem a fusão entre o movimento pedagógico renovador e a estética modernista. Entre as atividades desenvolvidas pelas crianças estão os desenhos, que compõem uma coleção formada por Mário de Andrade. O artigo examina os itens desse acervo, tomando-os como fontes e debruçando-se sobre aqueles que representam brincadeiras e jogos. Foram ilustradas brincadeiras tradicionais, equipamentos dos parques, jogos esportivos e manifestações folclóricas. Ressalte-se, ainda, a presença da natureza na composição dos desenhos, bem como traços de um desenvolvimento tecnológico.
A história e a disputa de sentidos
Authors: Almeida Silvio Luiz De
Published: December 2019

Sobre o autoritarismo brasileiro se propõe a apresentar de forma acessível e didática as raízes históricas do autoritarismo brasileiro. Trata-se de livro que surge ligado a um contexto político de crise e que se propõe a tarefa de disputar os sentidos da história diante dos perigos do revisionismo, da falsificação e da naturalização da violência política.
As regras da subversão
Authors: Rodrigues Lidiane Soares
Published: December 2019

O artigo trata  do “Grupo 2 do Seminário sobre O Capital de Marx”, promovido por Roberto Schwarz e Ruy Fausto em 1963, assim como de sua transformação na revista Teoria e Prática. Trata-se de estabelecer os nexos entre a morfologia e a produção intelectual dos membros participantes. Considerando o perfil e as posições institucionais dos “teóricos práticos” e dos autores por eles criticados, propõe uma interpretação a respeito dos atiçamentos para a “crítica da crítica”. No interior dessa configuração, Roberto Schwarz criou uma personagem geralmente tratada de modo pouco sistemático por seus comentadores, Bertha Dunkel, demonstrando que ela encerra uma chave de leitura importante e nada anedótica.
Roberto Schwarz e a sociologia paulista dos anos 1960
Authors: Helayel Karim , Brasil Junior Antonio
Published: December 2019

O artigo apresenta a hipótese de que, ao identificar a “volubilidade” como princípio formal do romance Memórias póstumas de Brás Cubas, de Machado de Assis, Roberto Schwarz estaria se posicionando frente às divergências entre Maria Sylvia de Carvalho Franco e Fernando Henrique Cardoso em torno da mobilização da categoria “patrimonialismo”. Localizaremos o argumento de Um mestre na periferia do capitalismo (1990), de Schwarz, diante das críticas de Franco ao uso por ela considerado improcedente da categoria “patrimonialismo” por parte de Cardoso. Discutiremos ainda as relações entre o princípio formal da “volubilidade” com a categoria “dilema”, proposta por Florestan Fernandes em seus trabalhos.
