Background

There is growing evidence that exercise modalities have considerable effects on Parkinson’s disease (PD). This trial aimed to provide a more detailed viewpoint of short-term and long-term treadmill training (TT) effects on some motor and non-motor features of PD.

Methods

In this prospective, randomized, single-blind clinical trial, 20 mild to moderate PD patients, admitted in Rasoul-e-Akram hospital in Tehran, Iran, were randomly allocated in case (11) and control (9) groups. Treadmill intervention was performed at moderate intensity with 60% of heart rate reserved (HRR) in two 30-min sessions/week for a duration of 10 weeks. Both the groups were evaluated for three times; at the baseline, 2 months later and then 2 months after the second evaluation. We assigned the Timed Up and Go test (TUG), 6-min walk test (6MW), and the SF-8 healthy questionnaire, for assessment of balance, functional capacity, and Quality of life (QoL), respectively.

Results

Balance and functional capacity were significantly improved in the case group after the intervention (TUG p-value: 0.003, 6MW p-value: 0.003). Moreover, the long-term analysis revealed significant results as well (TUG p-value: 0.001, 6MW p-value: 0.004). Mental condition’s scores of SF-8 in cases were not statistically different in short-term follow-up (F/U). However, analysis illustrated p-value: 0.016 for long-term assessment. The intervention induced significant changes in physical condition’s scores in both of the F/Us (PC p-value: 0.013).

Conclusions

This study provides evidence that a TT of mild to moderate intensity has significant and persistent benefits for the balance, functional capacity, and QoL in PD.

Subtitling’s cross-cultural expressivity put to the test: A cross-sectional study of linguistic and cultural representation across Romance and Germanic languages
Authors: Guillot Marie-Noëlle
Published: August 2019

This article focuses on linguistic and cultural representation in AVT as a medium of intercultural literacy. It has two objectives: it puts to the test increasingly accepted assumptions about AVT modalities’ distinctive meaning potential and expressive capacity, with a case study of communicative practices in their representation, via AVT, in subtitles across Romance and Germanic languages. The second objective is to make a start on a neglected question to date, by considering, concurrently, the respective potential for representation of different types of languages, Indo-European in the first instance, in different pair configurations.

The study applies to (Romance) French, Italian, Spanish and (Germanic) English and German and uses a cross-cultural pragmatics framework to explore representation, per se and comparatively across the languages represented in the main data, Lonnergan’s 2016 feature film Manchester by the Sea. Data is approached qualitatively from a target text end in the first instance and primarily, in a subset of scenes from across the film. Quantitative analysis is used complementarily for diagnostic purposes or as a complementary source of evidence, with initial focus on types of features identified in earlier studies as a locus of stylised representation in subtitling with evidence of distinctive pragmatic indexing (e.g. pronominal address, greetings, thanking).

The study is a pilot study and is exploratory at this stage, but part of a broader endeavour to inform debates about, and build up the picture of, AVT as cross-cultural mediation and, ultimately, promote our understanding of films in translation’s societal impact.
Subtitles and cinematic meaning-making: Interlingual subtitles as textual agents
Authors: Messerli Thomas C.
Published: August 2019

This theoretical paper adopts the point of view of the audience of subtitled films and outlines a theory of subtitles as communicative agents within the participation structures of film reception. Based on examples from three Swiss fiction films –Heidi(2015), Heimatland(2015) andDer Goalie bin ig(2014) – the following communicative effects are found and illustrated: uniformity, authorisation, foregrounding, aestheticisation, foreignisation. These effects are conceptualised in terms of Constitutive Communication theory and textual agency (Cooren. 2004. Textual agency: How texts do things in organizational settings.Organization11(3). 373–393. doi:10.1177/1350508404041998), which describe that by communicating with audiences, subtitles animate into being other participants in film discourse and contribute to what viewers take away in terms of characters, stories, the cultural aspects they represent and the source culture(s) from which the text is perceived to communicate.
(Dis)aligning across different linguacultures: Pragmatic questions from original to dubbed film dialogue
Authors: Ghia Elisa
Published: August 2019

In original and dubbed film dialogue, direct questions are a means to depict interpersonal relationships on screen. In particular, pragmatic questions (i.e. non-questioning, rhetorical interrogatives) are frequently employed to mark alignment among interactants, in the form of affiliative and disaffiliative interrogatives, respectively expressing positive and negative stance. Based on the exploration of thePavia Corpus of Film Dialogue, the current study aims at investigating the ways in which affiliative and disaffiliative questions are constructed in original English filmic speech and in Italian dubbing. The two dialogue types show rather high similarity in the distribution of pragmatic questions – with a notable prevalence of disaffiliative interrogatives carrying conflict-initiating role. However, different strategies are privileged in the two languages for the linguistic construction of stance. The English source text does not rely on a single and specific pattern to signal affiliation, while it marks disaffiliation through inserts, emotionally-loaded chunks and non-canonical word order in the interrogative. Conversely, dubbed Italian frequently draws on weak connectors to express disalignment and prefers different types of syntactically marked structures in the construction of affiliation. Findings thus suggest a certain degree of autonomy for dubbed dialogue in the selection of specific linguistic markers to transfer and re-portray interpersonal relationships in the target linguaculture.
Transfer of chemical elements from milk to dairy products

Published: August 2019

A pilot study was carried out to evaluate the transfer of As, Cd, Pb, Ni, Cr and Hg from milk to dairy products and to correlate their behavior with that of some components and macro-elements of milk. Due to the low level of these chemical elements in most common commercial products, hard cheese was produced starting from cow’s milk spiked with the analytes of interest. Several intermediate and final products coming from cheese making were sampled and analysed for content of fat, dry matter, proteins, macro and oligo-elements. The relationship between spiked elements and milk components was evaluated through both the study of concentration factors and the statistical analysis (Principal Component Analysis and correlation matrix). Except for As and Hg, a clear correlation between spiked elements and milk components was found so a likely bond with proteins, fat and dry matter was demonstrated. As for Pb, for which a legal limit (Maximum Level, ML) is set in the pertinent European regulations, it was found that the link with proteins could lead to an increase of this element concentration different from the mere concentration factor from milk to cheese. Furthermore, it was proven that the stage of ripening affected the variation of Pb concentration so this aspect should be deeply considered in case of setting a ML in cheese or extrapolating a ML from milk to cheese.

Exploring Differences in Excited-State Properties of Styryl-BODIPY Chromophores upon Change from α- to β-Substitution
Authors: Scholz Mirko , Hoffmann Caroline , Klein Johannes R. , Wirtz Marcel , Jung Gregor , Oum Kawon
Published: August 2019

We present a femtosecond pump-probe UV-Vis broadband transient absorption spectroscopy study of two styryl-substituted BODIPY chromophores with different position of the substituent. The α-substituted isomer shows typical BODIPY-type spectral features, such as sharp absorption and emission bands, a small Stokes shift and an excited-state lifetime in the 4 ns range, which only weakly depends on the solvent. In contrast, β-styryl-BODIPY features much broader steady-state absorption and emission spectra and a larger Stokes shift, particularly in polar solvents. Transient absorption spectroscopy including a complete global kinetic analysis reports a substantial decrease in S1 lifetime to 300 ps for polar solvents upon change from α- to β-substitution. In the case of the α-isomer, TD-DFT calculations identify a typical “cyanine-type” electron rearrangement upon S0 → S1 excitation accompanied by a slight reduction in dipole moment. In contrast, the same transition in the β-isomer shows strong intramolecular charge transfer (ICT) character involving a substantial increase in dipole moment. Assuming a simple energy-gap-law argument, the accelerated nonradiative decay of the β-isomer in polar solvents may be linked to the decrease of the S1(ICT)-S0 energy difference. BODIPY dyes with a conjugated substituent in β-position therefore suffer a substantial loss in fluorescence brightness in polar environments compared with their α-substituted counterparts. This might limit their applicability in fluorescence imaging.
Long-Lasting Input-Specific Experience-Dependent Changes of Hippocampus Synaptic Function Measured in the Anesthetized Rat
Authors: Levy Eliott R. J. , O’Reilly Kally C. , Fenton André A.
Published: August 2019

How experience causes long-lasting changes in the brain is a central question in neuroscience. The common view is that synaptic function is altered by experience to change brain circuit functions that underlie conditioned behavior. We examined hippocampus synaptic circuit functionin vivo,in three groups of animals, to assess the impact of experience on hippocampus function in rats. The “conditioned” group acquired a shock-conditioned place response during a cognitively-challenging, hippocampus synaptic plasticity-dependent task. The no-shock group had similar exposure to the environmental conditions but no conditioning. The home-cage group was experimentally naive. After the one-week retention test, under anesthesia, we stimulated the perforant path inputs to CA1, which terminate in stratum lacunosum moleculare (slm), and to the dentate gyrus (DG), which terminate in the molecular layer. We find synaptic compartment specific changes that differ amongst the groups. The evoked field EPSP (fEPSP) and pre-spike field response are enhanced only at the DG input layer and only in conditioned animals. The DG responses, measured by the population spiking activity and post-spike responses, are enhanced in both the conditioned and no-shock groups compared to home-cage animals. These changes are pathway specific because no differences are observed in slm of CA1. These findings demonstrate long-term, experience-dependent, pathway-specific alterations to synaptic circuit function of the hippocampus.

BIOCHEMICAL PROFILE OF GREEN AND RED ALGAE – A KEY FOR UNDERSTANDING THEIR POTENTIAL APPLICATION AS FOOD ADDITIVES
Authors: Vasileva Iv. , Ivanova J.
Published: August 2019

PURPOSE: With the improvements of the microalgal cultivation industry, it became possible to add algal biomass and its metabolites in foods in order to create a balanced and health-food. METHODS: By determining the growth and the biochemical composition (lipids, carbohydrates and proteins), two algal strains were evaluated as a potential source of food additives – the newly isolated strain of the green algae Scenedesmus sp. and the red algae Porphyridium cruentum). RESULTS: It turned out that in Scenedesmus sp. BGP the most abundant component were the proteins (up tp 45 %), which makes this alga an excellent unconventional protein producer. As opposed to it, the biochemical composition of Porphyridium cruentum was dominated by carbohydrates (up to 57%), but there was also a high content of some essential polyunsaturated fatty acids: arachidonic (AA, 20:4; 13-29%) and eicosapentaenoic acid (EPA, 20:5, 24-25%). CONCLUSIONS: Microalgae are a really remarkable source of biomass and a wide range of substances, but this area is poorly explored. Both of the microalgal strains proved to be important sources of functional ingredients that could be successfully used as food additives together or separately.
The anthropological assessment of the Late Roman cemetery at somogyszil-Dögkúti dűlő
Authors: Évinger Sándor , Bernert Zsolt
Published: August 2019

The results of a general anthropological examination of 140 individuals from a late Roman period cemetery at Somogyszil-Dögkút site are presented in this paper. The population had a more or less balanced sex ratio, lived a fundamentally peaceful life suggested by the low frequencey of bone injuries, and according to their morphoscopic traits, they all belonged to the Caucasoid group. Based on the biological distances calculated from selected linear measurements of male crania, the population of Somogyszil-Dögkút proved to be quite similar to several other late Roman period cemeteries in Transdanubia, as well as to some local Avar period series. This raises the possibility of a significant local continuity between the late Roman and late Avar period on this territory, however other potential explanations cannot be ruled out. Some anthropological characteristics of the human skeletal material unearthed from graves oriented differently than the cemetery's norm suggest the presence of immigrants in the community. Their biological background cannot be traced from the present data, however a few skeletal evidence proposes the probability of a Sarmatian origin.
Integral indicators of the swimming techniques effectiveness of highly qualified crawl-stroke swimmers
Authors: Krylov A.I. , Gorelov A.A. , Tretyakov A.A.
Published: August 2019

It is known that prominent world-class swimmers are characterized by the manifestation of specific abilities. These abilities allow to constantly maintain a stable speed swimming of different segments of the distance. In this case, highly qualified swimmers can increase the maximum speed of swimming on a segment of a given length. They achieve this by increasing the total external mechanical power. In this case, swimmers keep, and in some cases even reduce the power of the stroke. It is implemented the phase-specific principle of creating driving forces during each phase. At the same time, the principle of creating driving forces is common to all swimming locomotion. The article gives a rationale for the effectiveness of the integral criterion application for evaluating swimming techniques. The integral criterion for evaluating the swimming technique was applied at remote speeds of the entire spectrum of the competitive front crawl swimming program. Material . The study involved 9 highly qualified crawl-stroke swimmers, members of Russia national team. The age of the participants ranged from 18 to 24 years. It is studied the kinematic and kinetic characteristics of the front crawl swimming technique of highly qualified athletes at various competitive distances. The studies applied video recording of swimmer’s movements with OLYMPUS TG-5 camera (Vietnam) from a depth of 4.5 m. Three luminous markers located on the swimmer’s hips were applied to record the dynamic parameters of swimmer’s movements. The results of the swims were processed with Natatometry™ (Russia). Results . It was determined that swimmers demonstrated high indices of the intra-cyclic dynamic index (ICDI - Intra Cycle Dynamic Index) and the dynamic coordination index of the swimming cycle (DCI - Dynamic Coordination Index) at speeds in medium distances relative to speeds at sprint distances. Swimmers demonstrate the ability to generate a significant amount of promotional efforts at 100 m distance that ensure the achievement of high speeds. It is established that no general trends in ICDI changes in individual structural phases of the stroke. This indicates the demonstration of individual specific features in the swimming technique of each athlete. Conclusion . It is considered the feasibility of applying the integral indicators ICDI and DCI for a quantitative assessment of the intra cycle promotion forces interaction and hydrodynamic resistance forces arising at the level of an integral biomechanical system of the swimming cycle.

Published: August 2019

Purpose: The main purpose of this research was to show if there are differences between the Mediterranean diet and physical activity in students from Romania and Spain. Material: The study was carried out on a sample of 567 participants, 149 of which (24.69%) are from Romania (Transilvania University of Braşov) and 427 (75.31%) are students from Spain (University of Granada ). To evaluate adherence to the Mediterranean diet we used The Mediterranean Diet Quality Index (KIDMED), and for the assessment of the level of physical activity, we used the Physical Activity Questionnaire for Adolescents (PAQ-A). The reliability of the KIDMED was good (Cronbach’s α = 0.83) and for PAQ-A is 0.874. Statistical analyses were done through program IBM SPSS Statistics 22. The statistical indicators used in this study, were the following: standard deviation (SD), arithmetic average (X), chi-square test, Student’s T-test (t), percent%, Levene’s test, ANOVA One-Way. Results: The results of the variance analysis showed that there is no statistically significant relationship between the adherence to the Mediterranean diet and physical activity in Romanian students (F=0.517; p=0.598), or in Spanish students (F=0.255; p=0.775). Also, the results regarding adherence to the MD and PA was: poor adherence , n=31, (mean=29.06; standard deviation=3.723), average adherence , n=275, (mean=28.62; standard deviation=3.386), and high adherence, n=261 (mean=28.50; standard deviation=3.779). Conclusions: This study highlighted the fact that there are no significant differences regarding the adherence to the Mediterranean diet and the level of physical activity between the two countries (Romania and Spain). Unlike Spanish students, we found that Romanian students have a poor adherence to the MD.

The purpose of the research is to increase the level of cardiorespiratory fitness of female students by practicing Kangoo Jumps fitness in the practice of physical education. Material : participants are female students (n = 53, age - 19-20 years old). The study period was 10 months. Some females (n = 17) used Kangoo Jumps fitness in the practice of physical education. Indicators of physical and cardiorespiratory fitness were evaluated by the following methods: step test, Functional fitness assessment tests. Statistical data analysis was performed applying the Mann - Whitney U - test. Results : The test results (step test) revealed a significant (P <0.05) advantage of females practicing Kangoo Jumps fitness. The results are approximately the same for all females in most of the functional fitness assessment tests. The lowest weight gain (about 0.8 kg) is shown by females who used Kangoo Jumps fitness. Body mass indexes (from 1.8 to 2 kg.) were increased by students who used other types of fitness. Conclusions : It was revealed the possibility of increasing the cardiorespiratory fitness level of female students practicing Kangoo Jumps fitness in the practice of physical education. It was found the ability to control the increase in body weight of females.
Dispositional factors of personality professional development of the future teachers of physical education and sport
Authors: Stepanchenko N.I. , Briskin Y.A.
Published: August 2019

Purpose: The relevance of the problem of professional development of teachers led to the emergence of a large number of publications on this topic in the literature. But these publications do not clarify this very complex phenomenon and do not encourage the emergence of new scientific problems. This has determined the research interest. It is based on the need to clarify idea of internal factors on an intrapersonal level that contribute to the effective professional development of future physical education and sport teachers. The purpose of the work is to study them. Methods: Study participants were students from four Physical Education Faculties (physical education, sports, physical therapy and tourism) of higher education in the field of physical education in Western Ukraine. A total of 356 students participated in the study of internal factors on an intrapersonal level. The choice of research sample was random, the age of students - 18-19 years old. We used the questionnaire to determine the correlation between the two signalling systems and to determine the temperamental characteristics of students. To gather and analyze data we used the quantitative method. Result: Result showed that the second signalling system dominates in the majority of surveyed students. Most of the students with the prevailing second signalling system belong to the faculty of tourism (74%). We have determined the average level of the intellectual development sphere for all students without any exceptions. The highest rates were identified for the students of physical therapy faculty. The future teachers of physical education and sport showed the lowest results in communicative sphere. This is insufficient for professional and pedagogical activity. This group of students showed the best development in psychomotor qualities, even though the results were on average level. In general, we have not determined any significant discrepancies in psychomotor, intellectual and communicative spheres of the future teachers of physical education and sports in comparison with the students of other areas of training. Conclusions: We have demonstrated that the properties of the various personality aspects of the future physical education and sports teacher in the intellectual and communication domains are insufficient for professional work. They require the development of targeted effective methods for professional education and psycho-pedagogical means of motivation. The results of internal factors of students’ personality professional development diagnostics are supported by compliance of their characterological features to the professional demands but also by the conscious professional interests.

Published: August 2019

Resumo: O câncer renal é a 13ª neoplasia mais frequente no mundo. Entre 2012 e 2016, representou 1,48% das mortes por câncer no Brasil. A terapia de escolha para o tratamento de câncer renal metastático são os inibidores de tirosina quinase (ITK), sunitinibe e pazopanibe. Este artigo avalia o custo-efetividade do pazopanibe comparado ao sunitinibe no tratamento de câncer renal metastático. Foi realizada uma análise de custo-efetividade sob a perspectiva de um hospital federal do Sistema Único de Saúde. No modelo de árvore de decisão foram aplicados os desfechos de efetividade e segurança dos ITK. Os dados clínicos foram extraídos de prontuários e os custos diretos consultados em fontes oficiais do Ministério da Saúde. O custo de 10 meses de tratamento, englobando o valor dos ITK, procedimentos e manejo de eventos adversos, foi de R$ 98.677,19 para o pazopanibe e R$ 155.227,11 para o sunitinibe. Os medicamentos apresentaram efetividade estatisticamente equivalente e diferença estatisticamente significativa para o desfecho de segurança, no qual o pazopanibe obteve o melhor resultado. O pazopanibe, nesse contexto, é a tecnologia dominante quando os custos de tratamento são associados aos de manejo de eventos adversos.

Published: August 2019

ABSTRACT: The research intends to detect sources of contamination by Yersinia enterocolitica in the abattoir flowchart and endeavors to study its relation with the contamination in the farm. For this purpose, sixty pigs were followed up. In order to carry out the study, samples of faeces were collected from the animal farm, where the animals were originally kept and from the abattoir, directly from the animal’s rectum, after desensitization. Additionally, samples were also collected from the carcass, after passage into the hair removal machine, after evisceration, prior to entry into the cold chambre, from the jowls, and water of the scald tank, before the commencement of the abattoir as well as after the passage of the animals. Further, the isolates were obtained through microbiological analyzes, upon being identified by PCR and compared via rep-PCR. Basically, Yersinia enterocolitica was isolated from three bays in the original farm (20 %) and from 20 samples (6.67 %), obtained in the abattoir flowchart. Comparison made via rep-PCR revealed that the contaminated pigs on the farm could carry the microorganism to different points in the abattoir flowchart. However, apart from the farm, other sources of the contamination were reported to be more frequent and diverse. Indeed, the chins and the carcass at the entrance of the cold chamber were identified as the most critical points. Therefore, we concluded that Y. enterocolitica present in the gastrointestinal tract of pigs on the farm, cannot be eliminated throughout theabattoir flowchart and remain in the chambers intended for the cold room.

Published: August 2019

ABSTRACT Objective: to understand how family members and adult patients perceive the family's presence in emergency care. Method: qualitative study that used Symbolic Interactionism as a theoretical reference and the Data Grounded Theory as a methodological reference. Data collection took place in two emergency rooms, located in southern Brazil, between October 2016 and February 2017, through open interviews with four patients and eight relatives. Results: the relative presence in the emergency care was signified/perceived as positive, due to the benefits identified for patients, family members and health professionals. However, the experience was also marked by mishaps for the family-patient relationship, such as fear, doubts, anguish about the forced separation of family members and the experience of feelings of regret. Conclusion: due to the fact that the presence of the family in the emergency room is perceived as positive and beneficial, it is suggested that the health services, to the extent of their possibilities, implement this practice. However, such units need to be better prepared to mitigate the pitfalls faced by patients and their families.

ABSTRACT Objective: analyze the relationship between the perception of harm and benefits associated with the use of marijuana and its relation to real consumption, as well as the intention to use it in a context of regulatory changes, in young students, between 15 and 17 years old, of a public school in Bogota Colombia. Method: a quantitative, cross-sectional survey was carried out. 268 students in grade 9th to 11th from a public school in the city of Bogotá, Colombia participated of the study. Results: results reveled that there is an association between the perception of benefits and the consumption of marijuana. In addition, how a low perception of risk is associated with an intention to use in a context of legalization. Conclusion: this is one of the first studies in Colombia which explores the intention to use (at age 18) in a context of regulatory changes, as well as the attitude of young people towards the legalization of marijuana for medicinal and recreational use.

RESUMO O estudo de caso avalia uma ação para a redução do desperdício de alimentos em uma unidade de alimentação e nutrição (UAN) implantada em uma universidade pública. A avaliação do desperdício foi feita antes e depois das ações de capacitação dos funcionários da UAN e de uma campanha de conscientização e sensibilização dos comensais. Avaliou-se o desperdício pela análise da quantidade de alimentos consumida, do consumo per capita, do percentual de sobras, da quantidade média de sobra por consumidor, do percentual de resto de ingestão e do resto de ingestão per capita. Após as ações, as sobras de alimentos no balcão de distribuição e os restos de ingestão per capita foram reduzidos significativamente. As ações reportadas no presente estudo diminuíram de maneira expressiva a quantidade de alimentos desperdiçada.

In the monochrome-color dual-lens system, the gray image captured by the monochrome camera has better quality than the color image from the color camera, but does not have color information. To get high-quality color images, it is desired to colorize the gray image with the color image as reference. Related works usually use hand-crafted methods to search for the best-matching pixel in the reference image for each pixel in the input gray image, and copy the color of the best-matching pixel as the result. We propose a novel deep convolution network to solve the colorization problem in an end-to-end way. Based on our observation that, for each pixel in the input image, there usually exist multiple pixels in the reference image that have the correct colors, our method performs weighted average of colors of the candidate pixels in the reference image to utilize more candidate pixels with correct colors. The weight values between pixels in the input image and the reference image are obtained by learning a weight volume using deep feature representations, where an attention operation is proposed to focus on more useful candidate pixels and a 3-D regulation is performed to learn with context information. In addition, to correct wrongly colorized pixels in occlusion regions, we propose a color residue joint learning module to correct the colorization result with the input gray image as guidance. We evaluate our method on the Scene Flow, Cityscapes, Middlebury, and Sintel datasets. Experimental results show that our method largely outperforms the state-of-the-art methods.

Person Re-identification(re-ID) has great potential to contribute to video surveillance that automatically searches and identifies people across different cameras. Heterogeneous person re-identification between thermal(infrared) and visible images is essentially a cross-modality problem and important for night-time surveillance application. Current methods usually train a model by combining classification and metric learning algorithms to obtain discriminative and robust feature representations. However, the combined loss function ignored the correlation between classification subspace and feature embedding subspace. In this paper, we use Sphere Softmax to learn a hypersphere manifold embedding and constrain the intra-modality variations and cross-modality variations on this hypersphere. We propose an end-to-end dualstream hypersphere manifold embedding network(HSMEnet) with both classification and identification constraint. Meanwhile, we design a two-stage training scheme to acquire decorrelated features, we refer the HSME with decorrelation as D-HSME. We conduct experiments on two crossmodality person re-identification datasets. Experimental results demonstrate that our method outperforms the state-of-the-art methods on two datasets. On RegDB dataset, rank-1 accuracy is improved from 33.47% to 50.85%, and mAP is improved from 31.83% to 47.00%.
A Novel Framework for Robustness Analysis of Visual QA Models

Deep neural networks have been playing an essential role in many computer vision tasks including Visual Question Answering (VQA). Until recently, the study of their accuracy was the main focus of research but now there is a trend toward assessing the robustness of these models against adversarial attacks by evaluating their tolerance to varying noise levels. In VQA, adversarial attacks can target the image and/or the proposed main question and yet there is a lack of proper analysis of the later. In this work, we propose a flexible framework that focuses on the language part of VQA that uses semantically relevant questions, dubbed basic questions, acting as controllable noise to evaluate the robustness of VQA models. We hypothesize that the level of noise is negatively correlated to the similarity of a basic question to the main question. Hence, to apply noise on any given main question, we rank a pool of basic questions based on their similarity by casting this ranking task as a LASSO optimization problem. Then, we propose a novel robustness measure Rscore and two largescale basic question datasets (BQDs) in order to standardize robustness analysis for VQA models.
DeepCCFV: Camera Constraint-Free Multi-View Convolutional Neural Network for 3D Object Retrieval

3D object retrieval has a compelling demand in the field of computer vision with the rapid development of 3D vision technology and increasing applications of 3D objects. 3D objects can be described in different ways such as voxel, point cloud, and multi-view. Among them, multi-view based approaches proposed in recent years show promising results. Most of them require a fixed predefined camera position setting which provides a complete and uniform sampling of views for objects in the training stage. However, this causes heavy over-fitting problems which make the models failed to generalize well in free camera setting applications, particularly when insufficient views are provided. Experiments show the performance drastically drops when the number of views reduces, hindering these methods from practical applications. In this paper, we investigate the over-fitting issue and remove the constraint of the camera setting. First, two basic feature augmentation strategies Dropout and Dropview are introduced to solve the over-fitting issue, and a more precise and more efficient method named DropMax is proposed after analyzing the drawback of the basic ones. Then, by reducing the over-fitting issue, a camera constraint-free multi-view convolutional neural network named DeepCCFV is constructed. Extensive experiments on both single-modal and cross-modal cases demonstrate the effectiveness of the proposed method in free camera settings comparing with existing state-of-theart 3D object retrieval methods.
BiHMP-GAN: Bidirectional 3D Human Motion Prediction GAN

Human motion prediction model has applications in various fields of computer vision. Without taking into account the inherent stochasticity in the prediction of future pose dynamics, such methods often converges to a deterministic undesired mean of multiple probable outcomes. Devoid of this, we propose a novel probabilistic generative approach called Bidirectional Human motion prediction GAN, or BiHMP-GAN. To be able to generate multiple probable human-pose sequences, conditioned on a given starting sequence, we introduce a random extrinsic factor r, drawn from a predefined prior distribution. Furthermore, to enforce a direct content loss on the predicted motion sequence and also to avoid mode-collapse, a novel bidirectional framework is incorporated by modifying the usual discriminator architecture. The discriminator is trained also to regress this extrinsic factor r, which is used alongside with the intrinsic factor (encoded starting pose sequence) to generate a particular pose sequence. To further regularize the training, we introduce a novel recursive prediction strategy. In spite of being in a probabilistic framework, the enhanced discriminator architecture allows predictions of an intermediate part of pose sequence to be used as a conditioning for prediction of the latter part of the sequence. The bidirectional setup also provides a new direction to evaluate the prediction quality against a given test sequence. For a fair assessment of BiHMP-GAN, we report performance of the generated motion sequence using (i) a critic model trained to discriminate between real and fake motion sequence, and (ii) an action classifier trained on real human motion dynamics. Outcomes of both qualitative and quantitative evaluations, on the probabilistic generations of the model, demonstrate the superiority of BiHMP-GAN over previously available methods.
Learning Basis Representation to Refine 3D Human Pose Estimations

Published: August 2019

Estimating 3D human poses from 2D joint positions is an illposed problem, and is further complicated by the fact that the estimated 2D joints usually have errors to which most of the 3D pose estimators are sensitive. In this work, we present an approach to refine inaccurate 3D pose estimations. The core idea of the approach is to learn a number of bases to obtain tight approximations of the low-dimensional pose manifold where a 3D pose is represented by a convex combination of the bases. The representation requires that globally the refined poses are close to the pose manifold thus avoiding generating illegitimate poses. Second, the designed bases also have the property to guarantee that the distances among the body joints of a pose are within reasonable ranges. Experiments on benchmark datasets show that our approach obtains more legitimate poses over the baselines. In particular, the limb lengths are closer to the ground truth.
