description: Abstract
Objectives: The HIV (Human Immunodeficiency Virus) is an innovative germ that produced infection of HIV and AIDS. AIDS is a situation in individuals in which immune system is fail to carry its work and increase the infections of cancer and life threating poisons. The main objective of this study was to determine the relationship of stigma, discrimination and social support with psychological distress as symptoms of anxiety, depression, stress and level of stigma among HIV/AIDS patients. Further, the second purpose of the study was to treatment of the AIDS patient's emotional distress through cognitive behavior therapy. Design/Methods: Sample of 150 registered patients of AIDS selected trough purposive sampling technique from different Hospitals in district Gujrat, Punjab Pakistan. The age range of the participants were 18-70 years with mean age (36.43). Four scales as "HIV Stigma Scale, Discrimination Scale (subscale of HIV Stigma Scale), Social support Scale and Psychological Distress Scale" were used in the study. After scrutiny twenty (20) patients with high level of psychological distress was registered for intervention. Pearson Correlation, two step cluster and t-test analysis were used. Results: Results of study showed that stigma has positive relationship with psychological distress, anxiety, depression and stress (r = .405, p < .01, r= .307, p < .01, r = .467, p < .01, r = .332, p < .01, respectively). Cluster analysis of stigma showed that 33 patients were in low level of stigma, 55 in medium and 62 in high level stigma Discrimination has positive relationship with psychological distress, anxiety, depression and stress (r = .456, p < .01, r = .378, p < .01, r = .434, p < .01, r = .424, p < .01respectively). Social-support has negative relationship with psychological distress, anxiety, depression and stress ((r = -.283, p < .01, r = -.189, p <.05, r =.-.307, p < .01, r = -.275, p < .01 respectively). Results also indicated that Cognitive Behavior Therapy has great effective on Psychological distress as there is significant difference in mean scores of psychological distress of AIDS patients (M= 109.5, M= 94.00). Conclusion: The study shows that stigma and discrimination has a significant relationship with psychological distress (anxiety, depression and stress) and most of the patients lie in high level of stigma. Results also showed that social support has inverse relation with psychological distress as symptoms of anxiety, depression and stress. Psychological distress among AIDS patients can be overcome through the intervention as cognitive behavior therapy.

description: This thesis focuses on the study of low-cost steel and bamboo triangular lattice towers for small wind turbines. The core objective is to determine the material properties of bamboo and assess the feasibility of bamboo towers. Using the experimentally determined buckling resistance, elastic modulus, and Poisson’s ratio, a 12 m high triangular lattice tower for a 500W wind turbine has been modeled as a tripod to formulate the analytical solutions for the stresses and tower deflections, which enables design of the tower based on buckling strength of tower legs. The tripod formulation combines the imposed loads, the base distance between the legs and tower height, and cross-sectional dimensions of the tower legs. The tripod model was used as a reference for the initial design of the bamboo tower and extended to finite element analysis. A 12 m high steel lattice tower was also designed for the same turbine to serve as a comparison to the bamboo tower. The primary result of this work indicates that bamboo is a valid structural material. The commercial software package ANSYS APDL was used to carry out the tower analysis, evaluate the validity of the tripod model, and extend the analysis for the tower design. For this purpose, a 12 m high steel lattice tower for a 500 W wind turbine was examined. Comparison of finite element analysis and analytical solution has shown that tripod model can be accurately used in the design of lattice towers. The tower designs were based on the loads and safety requirements of international standard for small wind turbine safety, IEC 61400-2. For connecting the bamboo sections in the lattice tower, a steel-bamboo adhesive joint combined with conventional lashing has been proposed. Also, considering the low durability of bamboo, periodic replacement of tower members has been proposed. The result of this study has established that bamboo could be used to construct cost-effective and lightweight lattice towers for wind turbines of 500 Watt capacity or smaller. This study concludes that further work on joining of bamboo sections and weathering is required to fully utilize bamboo in practice. In comparison to steel towers, bamboo towers are economically feasible and easy to build. The tower is extremely lightweight, which justifies its application in remote areas, where the transportation is difficult.

description: By taking into account precursor films accompanying nanodroplets on trapezoidal substrates we show that on a mesoscopic level of description one does not observe the phenomenon of liquid-gas-substrate contact line pinning at substrate edges. This phenomenon is present in a macroscopic description and leads to non-unique contact angles which can take values within a range determined by the so-called Gibbs' criterion. Upon increasing the volume of the nanodroplet the apparent contact angle evaluated within the mesoscopic approach changes continuously between two limiting values fulfilling Gibbs' criterion while the contact line moves smoothly across the edge of the trapezoidal substrate. The spatial extent of the range of positions of the contact line, corresponding to the variations of the contact angle between the values given by Gibbs' criterion, is of the order of ten fluid particle diameters.

description: We use 3D radiative MHD simulations to investigate the formation and dynamics of small-scale (less than 0.5 Mm in diameter) vortex tubes spontaneously generated by turbulent convection in quiet-Sun regions with initially weak mean magnetic fields. The results show that the vortex tubes penetrate into the chromosphere and substantially affect the structure and dynamics of the solar atmosphere. The vortex tubes are mostly concentrated in intergranular lanes and are characterized by strong (near sonic) downflows and swirling motions that capture and twist magnetic field lines, forming magnetic flux tubes that expand with height and which attain magnetic field strengths ranging from 200 G in the chromosphere to more than 1 kG in the photosphere. We investigate in detail the physical properties of these vortex tubes, including thermodynamic properties, flow dynamics, and kinetic and current helicities, and conclude that magnetized vortex tubes provide an important path for energy and momentum transfer from the convection zone into the chromosphere.

description: We present the discovery of a source with broadband infrared photometric characteristics similar to Sakurai's Object. WISE J180956.27-330500.2 (hereafter, J1810-3305) shows very red WISE colors, but a very blue 2MASS [K] vs. WISE [W1 (3.4 micron)] color. It was not visible during the IRAS era, but now has a 12 micron flux well above the IRAS point source catalog detection limit. There are also indications of variability in historical optical photographic plates, as well as in multi-epoch AKARI mid-infrared measurements. The broadband infrared spectral energy distribution, post-IRAS brightening and multiwavelength variability are all characteristics also shared by Sakurai's Object - a post asymptotic giant branch (post-AGB) star which underwent a late thermal pulse and recently ejected massive envelopes of dust that are currently expanding and cooling. Optical progenitor colors suggest that J1810-3305 may have been of late spectral class. Its dramatic infrared brightening, and the detection of a late-type optical counterpart are consistent with a scenario in which we have caught an extremely massive dust ejection event (in 1998 or shortly before) during the thermal pulse of an AGB star, thus providing a unique opportunity to observe stellar evolution in this phase. J1810-3305 is the only source in the entire WISE preliminary data release with similar infrared SED and variability, emphasizing the rarity of such sources. Confirmation of its nature is of great importance.

description: The polarised spectrum of stellar radiation encodes valuable information on the conditions of stellar atmospheres and the magnetic fields that permeate them. In this paper, we give explicit expressions to estimate the magnetic field vector and its associated error from the observed Stokes parameters. We study the solar case where specific intensities are observed and then the stellar case, where we receive the polarised flux. In this second case, we concentrate on the explicit expression for the case of a slow rotator with a dipolar magnetic field geometry. Moreover, we also give explicit formulae to retrieve the magnetic field vector from the LSD profiles without assuming mean values for the LSD artificial spectral line. The formulae have been obtained assuming that the spectral lines can be described in the weak field regime and using a maximum likelihood approach. The errors are recovered by means of the hermitian matrix. The bias of the estimators are analysed in depth.

description: Ancient medical writers, depending upon their medical schools, had different views about the conceptualization and treatments for physical and mental disorders. This thesis compares the conceptualizations and treatments for three main types of madness described in antiquity – phrenitis, mania, and melancholia – provided by two authors – Aretaeus of Cappadocia and Caelius Aurelianus. Phrenitis is an ancient disorder that has no clear modern equivalent, mania and melancholia may have been the two halves of modern bipolar disorder, and melancholia has links to schizophrenia. Although these authors subscribed to different medical theories, and although Aretaeus placed more value on experience and Caelius referred more to theory, their treatments for the three disorders were similar. Ancient doctors treated physical symptoms, just as modern doctors do today. Disorders with predominant physical symptoms were better defined and had more definite treatments. Adherence to specific medical dogmas did not interfere with the day-to-day treatment of the mentally ill.

description: С позиций модульной организации растений исследована изменчивость архитектуры кроны у виргинильных и молодых генеративных особей Quercus robur L., произрастающих во вторичных фитоценозах бассейна Верхней и Средней Оки. По уровню освещенности исследованные фитоценозы подразделяются на три группы (в % от полной освещенности): мезофитные луга (100%), березняки разнотравные и сосняки с небольшими окнами (35–55%), сомкнутые сосняки (15–30%). Всего исследовано 210 особей. У каждой особи рассмотрены конфигурация, нарастание и ветвление осей основных структурных единиц кроны. Выборочно измерены значения количественных признаков побеговых систем. Выделено четыре архитектурных типа: «Луговой», «Опушечный», «Лесной 1», «Лесной 2». Особи лугового и опушечного типов произрастают в сообществах первой и второй групп освещенности соответственно. Особи лесных типов произрастают в сообществах третьей группы освещенности. В ряду от лугового типа к лесным типам происходит упрощение ветвления двухлетних побеговых систем с одновременным усложнением конфигурации и структуры ветвей от ствола и самого ствола. Таким образом, показано, что для Q. robur характерна значительная поливариантность побеговых систем, которая приводит к формированию качественно различающихся типов габитуса.

description: Lung cancer is the leading cause of cancer-related mortality worldwide. Adenocarcinoma, the most common subtype is primarily characterized by a combination of p53 and K-ras mutations. The activating K-ras mutation is frequently induced from carcinogens found within tobacco smoke, and is responsible for promoting an inflammatory microenvironment in the lung, which further enhances tumor progression. M2 polarized macrophages, the most common infiltrating cell type found within tumors, have been demonstrated to have several tumor-promoting effects such as promoting angiogenesis, suppressing inflammation and assisting with metastasis. However, there is conflicting evidence to the role of macrophages in lung cancer and in response to therapy. Using a mouse model that closely recapitulates features of human adenocarcinoma formation, in addition to syngeneic cell lines derived from both primary lung adenocarcinomas and metastases, we developed a model of quantifying tumor vasculature and areas of necrosis in 3-D ex vivo. In addition, we investigated the role of macrophage infiltration in tumor growth and in response to a vascular disrupting agent (VDA) 5,6-dimethylxanthenone-4-acetic acid (DMXAA) using subcutaneous, metastatic and spontaneously-derived lung adenocarcinomas. We found that despite the similar genetic background of the tumors, macrophage infiltration differed between tumor sites, and this appeared to result in differential response to DMXAA. Moreover, tumor-associated M2 macrophages were repolarized to a cytotoxic M1 phenotype in response to DMXAA; a novel role for this agent. In addition, we found that lung tumor development and progression in the K-rasLA1/+ mice was accelerated when crossed with Msh2-deficient mice, a key effector protein in the mismatch repair pathway, thus highlighting a role for MSH2 as a tumor suppressor in the development of lung cancer. In summary, lung cancer progression, which is based on exposure to external carcinogens, acquired mutations within tumor cells, and on infiltrating stromal cells such as macrophages within the tumor microenvironment, is a complex occurrence. Studying each of these facets using mouse models that closely echo human tumor progression may bring us closer to understanding human disease progression.

description: In conventional approach to the chameleon mechanism, by assuming a static and spherically symmetric solutions in which matter density and chameleon field are given by $ρ=ρ(r)$ and $ϕ=ϕ(r)$, it has been shown that mass of chameleon field is matter density-dependent. In regions of high matter density such as earth, chameleon field is massive, in solar system it is low and in cosmological scales it is very low. In this article we revisit the mechanism in cosmological scales by assuming a redshift dependence of the matter density and chameleon field, i.e. $ρ=ρ(z)$, $ϕ=ϕ(z)$. To support our analysis, we best fit the model parameters with the observational data. The result shows that in cosmological scales, the mass of chameleon field increases with the redshift, i.e. more massive in higher redshifts. We also find that in both cases of power-law and exponential potential function, the current universe acceleration can be explained by the low mass chameleon field. In comparison with the high redshift observational data, we also find that the model with power-law potential function is in better agreement with the observational data.

description: This thesis examines the relationships between the division of household labour and mental and physical health using survey data from 1,193 male and female lawyers in Canada. Household labour is examined in terms of time spent in housework on work days and non-work days, relative contribution to housework, and perceptions of fairness about the division of household tasks. The results indicate that housework time and relative contributions are not particularly detrimental to mental and physical health. Rather, time spent in housework only appears to be harmful when it interferes with weekends or when individuals feel that the division of housework is unfair, particularly if it is unfair to one’s spouse. Interestingly, these relationships do not differ for men and women. The results also suggest that work demands mediate the relationships between gender and health, as well as housework and health. Several avenues for further research are discussed.

description: We have measured the electroluminescence and photoluminescence of (9,7) semiconducting carbon nanotube devices and demonstrate that the electroluminescence wavelength is determined by the nanotube's chiral index (n,m). The devices were fabricated on Si3N4 membranes by dielectrophoretic assembly of tubes from monochiral dispersion. Electrically driven (9,7) devices exhibit a single Lorentzian shaped emission peak at 825 nm in the visible part of the spectrum. The emission could be assigned to the excitonic E22 interband transition by comparison of the electroluminescence spectra with corresponding photoluminescence excitation maps. We show a linear dependence of the EL peak width on the electrical current, and provide evidence for the inertness of Si3N4 surfaces with respect to the nanotubes optical properties.

description: We have analyzed the double-lined eclipsing binary system OGLE-LMC-CEP-1812 in the LMC and demonstrate that it contains a classical fundamental mode Cepheid pulsating with a period of 1.31 days. The secondary star is a stable giant. We derive the dynamical masses for both stars with an accuracy of 1.5%, making the Cepheid in this system the second classical Cepheid with a very accurate dynamical mass determination, following the OGLE-LMC-CEP-0227 system studied by Pietrzynski et al. (2010). The measured dynamical mass agrees very well with that predicted by pulsation models. We also derive the radii of both components and accurate orbital parameters for the binary system. This new, very accurate dynamical mass for a classical Cepheid will greatly contribute to the solution of the Cepheid mass discrepancy problem, and to our understanding of the structure and evolution of classical Cepheids.

description: The aim of this paper is to examine the role of women at the ministerial level in right-wing populist parties. To do so, we analyse the descriptive and substantive representation of women within the Hungarian and Polish right-wing populist cabinets. Using descriptive statistics, we examine the policy areas and relative prestige of their ministerial portfolios. To gain a deeper understanding of the role of women, we further provide an analysis of the roles of Beata Szydło as Polish prime minister and Katalin Novák as Minister without Portfolio for Families, Youth and the Elderly in Hungary. Within this analysis, we investigate their educational and political backgrounds and particularly focus on the gender aspects of their initiated family policies. Our results show that women within right-wing populist cabinets tend to govern traditionally ‘male’ and neutral policy areas; furthermore, they hold portfolios with similar prestige as do the men. The analysis of Beata Szydło and Katalin Novák indicates that women in executive offices are well educated and are more likely to become chief executives when their power is limited. Moreover, the investigation of the family policies demonstrates that they predominantly support the preservation of traditional family roles and strengthen them implicitly.
Improving High Sensitivity GNSS Receiver Performance in Multipath Environments for Vehicular Applications

description: Generally, standalone GNSS receiver architectures cannot provide a position accuracy suitable for use in vehicular applications in urban canyon scenarios. Specifically, GNSS signals are affected by the surrounding objects, such as high buildings, trees, etc., which will introduce multipath errors. Multipath arises from the reception of reflected or diffracted signals in addition to the line-of-sight (LOS) signal, and is one of the most detrimental error sources in GNSS positioning applications. By using a block processing high sensitivity receiver scheme with more correlators and/or longer coherent integration time, this thesis aims to obtain better positioning performance in the urban canyon areas. It was reported that signal correlation peaks (e.g., LOS correlation peaks, multipath correlation peaks) may be separated in the Doppler domain by a long coherent integration time. Generally, the dominant peak is utilized in high sensitivity receivers, however, this approach is not always optimal in multipath environments since it is not assured that the dominant peak is the LOS peak. In this regard, a LOS peak identification scheme is proposed in this work, which yields better positioning performance compared to the dominant peak scheme. Multipath distributions in the urban canyon area are characterized in this work. In particular, the Doppler frequency and code phase delay under different conditions are assessed as a function of vehicle speed and signal power. Results of this characterization is use to configure the receiver to better remove the multipath signals. More specifically, the multipath distribution will eventually affect the search strategy (i.e., search space size, coherent integration time) utilized in the high sensitivity receiver. Multipath directional-dependence phenomenon (i.e., the variation resulting from the direction of travel of the user) is observed during this process; and the multipath maximum Doppler offset and minimum Doppler offset are derived and verified by the real data, and finally used to detect errors in the receiver’s navigation solution. It is shown that most of the multipath peaks are removed in the receiver after using the proposed algorithm; consequently, pseudorange and Doppler accuracies are improved substantially. Also, different search space sizes and coherent integration times are compared in this work and an empirically-optimal search strategy is developed. Three data sets collected in the urban canyon areas are used to assess the proposed high sensitivity receiver strategy, it is shown that the position accuracies are better than 20 m.

description: How do sub-Saharan presidents form and manage their cabinets? Previous research on intra-executive relations has focused predominantly on patterns of patronage. Although informal mechanisms remain relevant in the policy-making process, formal institutions have gained in importance in sub-Saharan Africa since the early 1990s. However, little is known about the link between presidents’ constitutional power and their decisions to appoint, remove and reshuffle ministers. This article addresses this gap by analysing the impact of presidential power on three ministerial-level variables: ethnic cabinet composition, cabinet size and ministerial stability. Based on a framework combining formal and informal institutions, we argue that presidents use formal cabinet roles and relationships to employ informal power-sharing strategies. To capture presidential power, we construct a new index of eight powers specifically related to the presidential-ministerial relationship. The theoretical model is tested with a new dataset of 41 sub-Saharan African countries from 1990 to 2016. OLS regressions show that presidents with greater constitutional power form ethnically exclusive cabinets, increase cabinet size and raise minister stability, albeit the latter effect is not statistically significant. These findings shed new light on the impact of different institutional designs on intra-executive processes in general and, in particular, on presidential actions vis-à-vis cabinet ministers in sub-Saharan Africa.

description: We use polarized magneto-Raman scattering to study purely electronic excitations and the electron-phonon coupling in bulk graphite. At a temperature of 4.2 K and in magnetic fields up to 28 T we observe $K$-point electronic excitations involving Landau bands with $Δ|n|=0$ and with $Δ|n|=\pm2$ that can be selected by controlling the angular momentum of the excitation laser and of the scattered light. The magneto-phonon effect involving the $E_{2g}$ optical phonon and $K$-point inter Landau bands electronic excitations with $Δ|n|=\pm1$ is revealed and analyzed within a model taking into account the full $k_z$ dispersion. These polarization resolved results are explained in the frame of the Slonczewski-Weiss-McClure (SWM) model which directly allows to quantify the electron-hole asymmetry.

description: The electron, hole, and exciton g-factors and diamagnetic coefficients have been calculated using envelope-function theory for cylindrical InAs/InP quantum dots in the presence of a magnetic field parallel to the dot symmetry axis. A clear connection is established between the electron g-factor and the amplitude of the those valence-state envelope functions which possess non-zero orbital momentum associated with the envelope function. The dependence of the exciton diamagnetic coefficients on the quantum dot height is found to correlate with the energy dependence of the effective mass. Calculated exciton g-factor and diamagnetic coefficients, constructed from the values associated with the electron and hole constituents of the exciton, match experimental data well, however including the Coulomb interaction between the electron and hole states improves the agreement. Remote-band contributions to the valence-band electronic structure, included perturbatively, reduce the agreement between theory and experiment.

description: This paper presents modifications of the Diffie-Hellman (DH) key exchange method. The presented modifications provide better security than other key exchange methods. We are going to present a dynamic security that simultaneously realizes all the three functions with a high efficiency and then give a security analysis. It also presents secure and dynamic key exchange method. Signature, encryption and key exchange are some of the most important and foundational Crypto-graphical tools. In most cases, they are all needed to provide different secure functions. On the other hand, there are also some proposals on the efficient combination of key exchange. In this paper, we present a dynamic, reliable and secure method for the exchange of session key. Moreover, the proposed modification method could achieve better performance efficiency.

description: Discussion of scholar papers published until 10 July, 2020, on Ivermectin, and of some news that we can find about its use for Covid-19. A list of clinical trials is also given. For what concerns scholar papers, we report among them a preprint posted on 10 June in MedRχiv, which concludes that Ivermectin was associated with lower mortality during treatment of Covid-19. We report also the preprint, posted on 8 July in MedRχiv too, showing the result of a clinical trial. The preprint tells, in its conclusions that add-on use of Ivermectin is giving better results when compared to controls, in particular a significant shorter hospital stay. From news, we consider in particular the case of Iquitos, capital city of the Loreto Region in Peru, where, by May 25, Covid-19 cases and deaths had dropped notably, as reported on the web. The formulation of ivermectin used in Peru is also discussed, in particular that of the oral solution disclosed by the Peruvian Government.
description: Before reading this work, please consider that I am not a physician. I do not suggest the use of ivermectin. I am not touting this drug. This analysis of publications and news about ivermectin is made in the framework of a wider investigation about information concerning drugs used for Covid-19.

description: Theoretical studies of structure formation find an inverse proportionality between the concentration of dark matter haloes and virial mass. This trend has been recently confirmed for virial masses Mvir > ~6e12 Msun by the observation of the X-ray emission from the hot halo gas. We present an alternative approach to this problem, exploring the concentration of dark matter haloes over galaxy scales on a sample of 18 early-type systems. Our c-Mvir relation is consistent with the X-ray analysis, extending towards lower virial masses, covering the range from ~4e11 Msun up to 5e12 Msun. A combination of the lensing analysis along with photometric data allows us to constrain the baryon fraction within a few effective radii, which is compared with prescriptions for adiabatic contraction (AC) of the dark matter haloes. We find that the standard methods for AC are strongly disfavored, requiring additional mechanisms -- such as mass loss during the contraction process -- to play a role during the phases following the collapse of the haloes.

description: We provide new, high-resolution A(Ks) extinction maps of the heavily reddened Galactic midplane based on the Rayleigh-Jeans Color Excess ("RJCE") method. RJCE determines star-by-star reddening based on a combination of near- and mid-infrared photometry. The new RJCE-generated maps have 2 x 2 arcmin pixels and span some of the most severely extinguished regions of the Galaxy -- those covered with Spitzer+IRAC imaging by the GLIMPSE-I, -II, -3D, and Vela-Carina surveys, from 256

description: The absence of recognizable, low energy quantum gravitational effects requires that some asymptotic series expansion be wonderfully accurate, but the correct expansion might involve logarithms or fractional powers of Newton's constant. That would explain why conventional perturbation theory shows uncontrollable ultraviolet divergences. We explore this possibility in the context of the mass of a charged, gravitating scalar. The classical limit of this system was solved exactly in 1960 by Arnowitt, Deser and Misner, and their solution does exhibit nonanalytic dependence on Newton's constant. We derive an exact functional integral representation for the mass of the quantum field theoretic system, and then develop an alternate expansion for it based on a correct implementation of the method of stationary phase. The new expansion entails adding an infinite class of new diagrams to each order and subtracting them from higher orders. The zeroth order term of the new expansion has the physical interpretation of a first quantized Klein-Gordon scalar which forms a bound state in the gravitational and electromagnetic potentials sourced by its own probability current. We show that such bound states exist and we obtain numerical results for their masses.

description: The evolution of spatially homogeneous and isotropic cosmological models containing a perfect fluid with equation of state p=wρ and a cosmological constant Λ is investigated for arbitrary combinations of w and Λ, using standard qualitative analysis borrowed from classical mechanics. This approach allows one to consider a large variety of situations, appreciating similarities and differences between models, without solving the Friedmann equation, and is suitable for an elementary course in cosmology.

description: Humanoid robots have shown success in many domestic applications. State-of-the-art robots can deliver drinks, fold laundry, cook meals, and even automatically plug themselves in for charging. When developing a new robot system capable of executing such tasks, many di erent subsystems must work in concert, such as sensors for perception, drivers for low-level actuation, and some kind of intelligent, task-executive control. In this research, a situational awareness framework is proposed that combines these elements within an information fusion hierarchy to solve the problem of complex task execution. The framework is implemented on a H20 humanoid robot using the Robot Operating System (ROS) for system management and using the Point Cloud Library (PCL) for perception algorithms. The framework represents the overall control of the robot through an intuitive layering of low-level sensor readings to high-level action execution and establishes a proof-of-concept pick-and-place behaviour built within a vision-based Learning from Demonstration (LFD) architecture.
