Published: January 2022

Recently, the use of biomass energy has been growing worldwide on an accelerated trajectory, with the prospect of staying among the main renewable energy sources for the coming decades, along with wind and solar energy. Brazil is the largest producer of sugarcane on the planet and the second-largest producer of ethanol. But in addition to sugar, first-generation ethanol, and vinasse (for ferti-irrigation), other by-products and process residues from the plants (such as bagasse, filter cake, vinasse, straw, and sugarcane tip) can be used for the production of thermal and electric energies and also second-generation ethanol and biogas fuels. In this context, this paper presents the current scenario of sugarcane biomass in Brazil, discussing issues involving the use of sugar-alcohol by-products for bioenergy and biofuel production. Furthermore, a study on the reuse of sugarcane bagasse fibers for the production of eco-composite material is also presented. Finally, the concepts of biomass energy are described from a bibliographic survey and the previous experiences of the authors.

A collocation methods based on the quadratic quadrature technique for fractional differential equations
Authors: Bu Sunyoung ,   Department of Liberal arts, Hongik University, Sejong, 30016, South Korea
Published: January 2022

In this paper, we introduce a mixed numerical technique for solving fractional differential equations (FDEs) by combining Chebyshev collocation methods and a piecewise quadratic quadrature rule. For getting solutions at each integration step, the fractional integration is calculated in two intervals-all previous time intervals and the current time integration step. The solution at the current integration step is calculated by using Chebyshev interpolating polynomials. To remove a singularity which belongs originally to the FDEs, Lagrangian interpolating technique is considered since the Chebyshev interpolating polynomial can be rewritten as a Lagrangian interpolating form. Moreover, for calculating the fractional integral on the whole previous time intervals, a piecewise quadratic quadrature technique is applied to get higher accuracy. Several numerical experiments demonstrate the efficiency of the proposed method and show numerically convergence orders for both linear and nonlinear cases.

In this paper, a novel one dimensional chaotic map $ K(x) = \frac{\mu x(1\, -x)}{1+ x} $, $ x\in [0, 1], \mu > 0 $ is proposed. Some dynamical properties including fixed points, attracting points, repelling points, stability and chaotic behavior of this map are analyzed. To prove the main result, various dynamical techniques like cobweb representation, bifurcation diagrams, maximal Lyapunov exponent, and time series analysis are adopted. Further, the entropy and probability distribution of this newly introduced map are computed which are compared with traditional one-dimensional chaotic logistic map. Moreover, with the help of bifurcation diagrams, we prove that the range of stability and chaos of this map is larger than that of existing one dimensional logistic map. Therefore, this map might be used to achieve better results in all the fields where logistic map has been used so far.
This Is Not Reality (Ceci n'est pas la réalité): Capturing the Imagination of the People Creativity, the Chinese Subaltern, and Documentary Storytelling
Authors: Voci Paola
Published: January 2022

How has documentary(re)presented subaltern creativity? Focusing on post-socialist, globalizing China, I examine documentary narratives by and about the creative subaltern originating from Chinese “cool cities” and expanding in the virtual space of global digital media. In these narratives, the creative subaltern has appeared obliquely, tangential to other narratives, subordinate to internationally recognized artists, or with a more central role, as the author or the protagonist of documentary films. I analyze these narratives’ entanglement with elitist definitions of creativity, the representation of subaltern reality, the expression of subjectivity, and the tension between the political and the personal.
I argue that documentary has played an important albeit ambiguous role—provocative and empowering, but also, at times, formulaic and constricting—in shaping the discourse on the subaltern as a creative subject, by amplifying creativity’s indexicality to the real and obfuscating its imaginative quality and its ambition of breaking free from the real. Reflecting on the contemporary relevance of the Free Cinema movement’s advocacy for a subjective, personal approach to capturing the “imagination of the people” and exploration of lyric realism in documentary filmmaking, I propose that documentary can and should dare to “make poetry.” Forms of documentary expressivity such as poetic, not plot-driven narratives can reconcile imagination with reality and offer alternative, more appropriate means of capturing the complexity, heterogeneity, and contradictoriness of the subaltern condition, and for subaltern creativity to be expressed, appreciated, and affirmed.
“Retweet for More”: The Serialization of Porn on the Twitter Alter Community
Authors: Cao Ruepert Jiel Dionisio
Published: January 2022

This article examines the notion of seriality in the context of the Filipino alter community, a network of Twitter users producing, distributing, and consuming pornographic images. The alter community is prominent among Filipino gay men who satisfy their need for sexual arousal, collective identity, and validation of their sexuality in the alter community. Seriality is influenced by technological features and affordances of a media platform. In the case of Twitter, the platform’s short form formats and real-time content generation fosters a particular kind of seriality. This essay analyzes data from online observations, content analysis of tweets and profiles, and interviews and is informed by theories on seriality, gay sexuality, and Internet studies. In situating seriality within the context of gay amateur porn economy, this article argues that serial pornography is instrumental in satisfying both present and long-standing affective, sexual, and social needs of gay men. These needs, this essay claims, stem from long history of minoritization of homosexuality. As Twitter renders older tweets ephemeral and quantifies social engagement, seriality enables gay men to satisfy the aforementioned needs longer. Furthermore, this essay proposes that serial porn on Twitter brings new insights to how seriality is conceived. Serial porn images are strategically and carefully constructed narratives of sexual encounters aimed at garnering higher social engagement and validation. Thus, serial narratives can resolve present and urgent affective tensions and needs that unravel within an ongoing life narrative rather than working toward supporting a plausible ending, as seen in other serial forms. This article contributes to an understanding of how pornographic images and serial narratives fit into consumerist culture and how platforms exploit long-standing affective needs of sexual minorities to ensure extended production and consumption of contents.
Love and Duty: Translating Films and Teaching Online Through a Pandemic
Authors: Rea Christopher
Published: January 2022

The Chinese Film Classics project, launched in 2020, is an online research and teaching initiative aimed at making early Chinese films and cinema history more accessible to the general public. Led by Christopher Rea at the University of British Columbia, the project is centered on the website http://chinesefilmclassics.org and the companion YouTube channel Modern Chinese Cultural Studies. These two platforms together host new English translations of over two dozen Republican-era Chinese films, over two hundred film clips organized into thematic playlists, and a free online course of video lectures on Chinese film classics. This essay tells the story of how the Chinese Film Classics project grew from being a book project into a multiplatform translation, teaching, and publication project during the COVID-19 pandemic. Online teaching and social media publication involved multiple global storytellers: filmmakers, educators, translators, students, and the broader Internet public. How might moving things online change, or improve, the practice of cultural history? Rea highlights in particular the practical considerations facing the translator and gives examples of how, in a social media context, some of the stories are told not by creators and audiences but by data analytics.

Mobility Markov Chain and Matrix-Based Location-Aware Cache Replacement Policy in Mobile Environment
Authors: Gupta Ajay Kumar , Shanker Udai
Published: January 2022

In the location-aware services, past mobile device cache invalidation-replacement practises used are ineffective if the client travel route varies rapidly. In addition, in terms of storage expense, previous cache invalidation-replacement policies indicate high storage overhead. These limitations of past policies are inspiration for this research work. The paper describes the models to solve the aforementioned challenges using two different approaches separately for predicting the future path for the user movement. In the first approach, the most prevalent sequential pattern mining and clustering (SPMC) technique is used to pre-process the user's movement trajectory and find out the pattern that appears frequently. In the second approach, frequent patterns are forwarded into the mobility Markov chain and matrix (MMCM) algorithm leading to a reduction in the size of candidate sets and, therefore, efficiency enhancement of mining sequence patterns. Analytical results show significant caching performance improvement compared to previous caching policies.
A Study on Deep Learning Model Autonomous Driving Based on Big Data
Authors: Karl Yoki Donzia Symphorien , Kim Haeng-Kon , Geum Young-Pil
Published: January 2022

Autonomous driving requires a large amount of data to improve performance, and the authors tried to solve this problem by using CARLA simulation. However, there is a suggestion that the use of CARLA simulation in research institutes and companies that research autonomous driving such as Tesla results in poor results, and that real data, not simulations, are needed in the end. Therefore, the authors propose a method to obtain real data in real-time. In order to utilize the actual data, when the sensor installed in the vehicle recognizes the dangerous situation, the embed-ded device detects and judges the danger 5-10 seconds in advance, and the acquired various dangerous situation data is sent to the iCloud(server) for retraining with new data. Over time, the learning model's performance gets better and more perfect. The deep learning model used for training is a detection model based on a convolution neural network (CNN), and a YOLO model that shows optimal detection performance and speed will be used. The authors propose a con-nectivity vehicle technology system solution, which is an important part of autonomous driv-ing, using big data-based deep learning algorithms. Connectivity autonomous driving uses big data to provide access to a high level of autonomy. A technology that provides access to a high level of autonomy is very important for vehicle development, and continuous and stable access to big data is also important for successful connectivity autonomous driving. In this study, the authors implement and extensively evaluate the system by autoware under various settings using a popular end-to-end self-driving software Autoware on NVIDIA Corporation for the development of autonomous vehicles, and evaluate the performance of Autoware on (GPUs). Autoware is a popular open-source software project that offers a complete set of autonomous driving modules that include positioning, detection, prediction, planning, and control mod-ules, which converts Windows-based sources to ROS-based sources given a source and des-tination. The authors use the popular open-source Autoware software to provide an analysis model de-sign and the development of an autonomous vehicle equipped with a system is performed. This paper proposes a UML diagram including the design of the Deep Learning Process Model Autonomous Driving Based on Big and software in it. The software is called embed-ded software. Model-based testing is a resolution for testing embedded software.
Mineralogical and geochemical characterisation of the Kipawa syenite complex, Quebec: implications for rare-earth element deposits
Authors: Matte S , Constantin M , Stevenson R
Published: January 2022

The Kipawa rare-earth element (REE) deposit is located in the Parautochton zone of the Grenville Province 55 km south of the boundary with the Superior Province. The deposit is part of the Kipawa syenite complex of peralkaline syenites, gneisses, and amphibolites
that are intercalated with calc-silicate rocks and marbles overlain by a peralkaline gneissic granite. The REE deposit is principally composed of eudialyte, mosandrite and britholite, and less abundant minerals such as xenotime, monazite or euxenite. The Kipawa Complex outcrops as a series of thin,
folded sheet imbricates located between regional metasediments, suggesting a regional tectonic control. Several hypotheses for the origin of the complex have been suggested: crustal contamination of mantle-derived magmas, crustal melting, fluid alteration, metamorphism, and hydrothermal activity.
Our objective is to characterize the mineralogical, geochemical, and isotopic composition of the Kipawa complex in order to improve our understanding of the formation and the post-formation processes, and the age of the complex.
The complex has been deformed and metamorphosed with evidence of melting-recrystallization textures among REE and Zr rich magmatic and post magmatic minerals. Major and trace element geochemistry obtained by ICP-MS suggest that syenites, granites and monzonite of the complex have within-plate A2
type anorogenic signatures, and our analyses indicate a strong crustal signature based on TIMS whole rock Nd isotopes. We have analyzed zircon grains by SEM, EPMA, ICP-MS and MC-ICP-MS coupled with laser ablation (Lu-Hf). Initial isotopic results also support a strong crustal signature. Taken
together, these results suggest that alkaline magmas of the Kipawa complex/deposit could have formed by partial melting of the mantle followed by strong crustal contamination or by melting of metasomatized continental crust. These processes and origins strongly differ compare to most alkaline
complexes in the world. Additional TIMS and LA-MC-ICP-MS analyses are planned to investigate whether all lithologies share the same strong crustal signature.

In response to the COVID-19 pandemic, clinical research groups across the world developed trial protocols to evaluate the safety and efficacy of treatments for COVID-19. Despite this initial enthusiasm, only a small portion of these protocols were implemented. Of those implemented, a fraction successfully recruited their target sample size to analyze and disseminate findings. More than a year and a half into the COVID-19 pandemic, only a few clinical trials evaluating treatments for COVID-19 have generated new evidence. Productive randomized platform clinical trials evaluating COVID-19 treatments may attribute their success to intentional investments in developing resilient clinical trial infrastructures. Health system resiliency discourse provides a conceptual framework for characterizing attributes for withstanding shocks. This framework may also be useful for contextualizing the attributes of productive clinical trials evaluating COVID-19 therapies. We characterize the successful attributes and lessons learned in developing the TOGETHER Trial infrastructure using a health system resiliency framework. This framework may be considered by clinical trialists aiming to build resilient trial infrastructures capable of responding rapidly and efficiently to global health threats.

AimThis study was conducted to determine the prevalence of contact lens (CL) use among university students, their awareness on CL, and CL users’ practices for the cleaning and care of CLs.MethodsThe data of this cross-sectional study were collected between April 2019 and July 2019. The sample consisted of university students who volunteered to participate in the study. The data obtained from the study were evaluated by Statistical Package for the Social Science (SPSS) 22.0 package program in computer environment. Results929 students participated in the study and the average age of them was 21.99±1.85 years (Min. 18 – Max. 24), and it was determined that 36.6% (n=340) of the participants were male, 10.2% (n=95) of the total were using CL, 91.6% (n=87) of them used CL due to visual impairment. When students’ levels of knowledge about the hygiene and care in CL use were examined 85.4% (n=82) washed their hands before wearing/removing CL, 85.3% (n=81) cleaned the lens container and filled it with new solution when the solution in the container was reduced, 18.5% (n=17) continued wearing CL while sleeping, 6.5% (n=6) washed CL with tap water, and 28.3% (n=26) of them stated that they swam in the sea with CL. It was determined that the prevalence of CL use was higher (p= .045) among smoking students.ConclusionHealth professionals are important in the trainings to be given to increase the students’ knowledge of hygiene and care regarding the use of CL. More studies are needed on the effect of smoking status on CL use.
Extreme Weather and the Reproductive Success of a Long-lived Pelagic Seabird.
Authors:   , Baker Bryony
Published: January 2022

Seabirds are in decline globally and climate change is likely to increase the pressure on already struggling species. The indirect effects of climate change are widely studied, they have been shown to have a significant effect on both seabird survival and reproductive success, but the direct effects are less well understood. Climate predictions suggest that one of the direct effects, extreme weather, is predicted to increase in both frequency and intensity. Skomer Island is the largest Manx Shearwater colony in the world and the population has been increasing over recent decades, but the specific effects of extreme weather on reproductive success are unknown. This study compared the effects of average and extreme weather conditions on Manx Shearwater reproductive success, taking into account the effect of known breeding pairs and the potential effects of individual experience. It also considered the effect of inter-specific competition between shearwaters and Atlantic puffins on shearwater reproductive success. This study found that colony-level reproductive success showed no significant trend over the study period of 1995-2019, however fledging success showed a significant decline. When individual-level analysis was carried out no such trend was found: experienced breeders may be more likely to successfully raise a chick. Extreme weather was shown to have significant effects on reproductive success at the individual-level, particularly on fledging success, but this did not cause a significant decrease in fledging success over the study period. Population estimates show that shearwaters are increasing on Skomer and it is clear that weather, extreme or not, is not currently the most significant factor in determining reproductive success of Manx Shearwaters. This study also found no evidence that puffins are influencing the reproductive success of Manx Shearwaters on Skomer Island. The effects of climate change, indirect and direct, will interact and have many complex effects, especially if predictions regarding future climate change are met. Extreme weather and the effects of demography can only be studied where long- term datasets exist, therefore projects such as this are vital for ongoing seabird research and conservation.
Ingredients and proposals for defining the contours of a networked observatory of the ecological capital of the Rhone watershed: contributions from the OSAGE (Scientific Observatory in support of land managers) and CECN (Ecosystem Accounting for Natural Capital) approaches.

L’article aborde les enjeux liés au développement de l’observation et de l’évaluation environnementales, qui répondent pour partie à des politiques incitatives mais aussi à des prises de conscience tant institutionnelles que citoyennes. Notre contribution s’appuie sur l’expérimentation d’une approche systémique de comptabilité écologique (Comptabilité Écosystémique du Capital Naturel, CECN) à l’échelle du bassin versant du Rhône, en la confrontant à un modèle théorique, l’observatoire OSAGE. L’objectif, assorti de préconisations scientifiques, techniques et organisationnelles, fruits de cette confrontation, vise à s’interroger sur les capacités de déploiement de l’outil de CECN en un observatoire des ressources territoriales structuré par les dispositifs scientifique, technique et organisationnel d’OSAGE. La mise en œuvre efficace d’un tel outil appelle un besoin urgent de politiques publiques plus cohérentes en matière de données (temps, espaces, protocoles), enrichies par des plateformes participatives multi-acteurs, l’ensemble pouvant permettre de coordonner et de rendre opérants les choix et les protocoles de constitution de données (formats, modalités d’échanges, etc.).
On the Taylor expansion of $\lambda$-terms and the groupoid structure of their rigid approximants
Authors: Olimpieri Federico , Auclair Lionel Vaux
Published: January 2022

We show that the normal form of the Taylor expansion of a $\lambda$-term is
isomorphic to its B\"ohm tree, improving Ehrhard and Regnier's original proof
along three independent directions. First, we simplify the final step of the
proof by following the left reduction strategy directly in the resource
calculus, avoiding to introduce an abstract machine ad hoc. We also introduce a
groupoid of permutations of copies of arguments in a rigid variant of the
resource calculus, and relate the coefficients of Taylor expansion with this
structure, while Ehrhard and Regnier worked with groups of permutations of
occurrences of variables. Finally, we extend all the results to a
nondeterministic setting: by contrast with previous attempts, we show that the
uniformity property that was crucial in Ehrhard and Regnier's approach can be
preserved in this setting.
Finely Crafted Features for Traffic Sign Recognition
Authors: Li Wei , Song Haiyu , Wang Pengjie
Published: January 2022

Traffic sign recognition (TSR) is the basic technology of the Advanced Driving Assistance System (ADAS) and intelligent automobile, whileas high-qualified feature vector plays a key role in TSR. Therefore, the feature extraction of TSR has become an active research in the fields of computer vision and intelligent automobiles. Although deep learning features have made a breakthrough in image classification, it is difficult to apply to TSR because of its large scale of training dataset and high space-time complexity of model training. Considering visual characteristics of traffic signs and external factors such as weather, light, and blur in real scenes, an efficient method to extract high-qualified image features is proposed. As a result, the lower-dimension feature can accurately depict the visual feature of TSR due to powerful descriptive and discriminative ability. In addition, benefiting from a simple feature extraction method and lower time cost, our method is suitable to recognize traffic signs online in real-world applications scenarios. Extensive quantitative experimental results demonstrate the effectiveness and efficiency of our method.
