Improving Spectral Efficiency of D2D Cellular Networks through RF Energy Harvesting
Venue: 2016 IEEE Global Communications Conference (GLOBECOM)

In this paper, we consider device to device (D2D) communication underlaying cellular networks, where D2D users harvest radio frequency (RF) power from uplink cellular transmissions. This paper addresses two important issues for energy harvesting based D2D cellular networks. The first is how the energy harvested from cellular ambient RF signals affects the D2D spectral efficiency. Using tools from stochastic geometry, we investigate this issue by first characterizing the transmission probability of D2D transmitter as the probability of having enough battery power, and then obtaining analytic expressions of the spectral efficiency for D2D and cellular networks. The second issue is related to the cellular spectral efficiency: the more RF energy D2D users can harvest, the higher their transmission probability becomes, which leads to generating more interference in the cellular network. We carry out simulations to understand this impact of RF energy harvesting on the spectral efficiency of both D2D and cellular networks. Results show promising improvement to the whole network, in terms of the weighted spectral efficiency, when employing RF harvesting technology and when there are enough available channels in the network.
Influencia del riego y radiacion solar sobre el contenido de fitoquimicos en la piel de frutos de aguacate 'Hass'

La actividad fotosintetica y la concentracion de fitoquimicos en las plantas son muy influenciadas por la radiacion solar incidente y su disminucion provoca importantes cambios en la concentracion tanto de clorofilas como de compuestos producidos en las rutas del metabolismo secundario. Aunado a las condiciones de iluminacion, la disponibilidad de agua y la temperatura causan cambios bioquimicos y fisiologicos que afectan el metabolismo, desarrollo y rendimiento de un cultivo. El cambio climatico es determinante para que estreses bioticos y/o abioticos se presenten durante el desarrollo de las plantas por lo que el conocimiento de sus efectos podria resultar en un manejo agronomico mas adecuado. El objetivo de este estudio fue cuantificar el contenido de clorofila y compuestos fenolicos totales en la piel de frutos de aguacate 'Hass' cultivados bajo diferente manejo de agua (con y sin riego) y cobertura del fruto (cubiertos y descubiertos) El manejo de agua no modifico el contenido de fitoquimicos en la piel de los frutos. Respecto al grado de exposicion a la radiacion solar, los frutos descubiertos presentaron una concentracion mayor de compuestos fenolicos totales y clorofila, comparados con los frutos cubiertos (estresados por falta de luz)
Influencia del riego y radiacion solar sobre el contenido de fitoquimicos en la piel de frutos de aguacate "Hass"

espanolThe photosynthetic activity and concentration of phytochemicals in plants are strongly influenced by solar radiation and its reduction causes significant changes in concentration of both chlorophyll and compounds produced in secondary metabolism pathways. In addition to lighting conditions, water availability and temperature cause biochemical and physiological changes affecting metabolism, development and crop yield. Climate change is crucial for biotic and abiotic stresses to be present during plant development, so the knowledge of its effects could result in a better crop management. The objective of this study was to quantify chlorophyll content and total phenolic compounds in peel of 'Hass' avocado grown under different water management (with and without irrigation) and fruit coverage (covered and uncovered) Water management did not modify the content of phytochemicals in peel. Regarding the degree of exposure to solar radiation, uncovered fruits had a higher concentration of total phenolic compounds and chlorophyll, compared with covered fruit (stressed by lack of light) MultipleLa actividad fotosintetica y la concentracion de fitoquimicos en las plantas son muy influenciadas por la radiacion solar incidente y su disminucion provoca importantes cambios en la concentracion tanto de clorofilas como de compuestos producidos en las rutas del metabolismo secundario.

Online Reconstruction of Indoor Scenes from RGB D Streams
Venue: 2016 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)

A system capable of performing robust online volumetric reconstruction of indoor scenes based on input from a handheld RGB D camera is presented. Our system is powered by a two pass reconstruction scheme. The first pass tracks camera poses at video rate and simultaneously constructs a pose graph on the fly. The tracker operates in real time, which allows the reconstruction results to be visualized during the scanning process. Live visual feedbacks makes the scanning operation fast and intuitive. Upon termination of scanning, the second pass takes place to handle loop closures and reconstruct the final model using globally refined camera trajectories. The system is online with low delay and returns a dense model of sufficient accuracy. The beauty of this system lies in its speed, accuracy, simplicity and ease of implementation when compared to previous methods. We demonstrate the performance of our system on several real world scenes and quantitatively assess the modeling accuracy with respect to ground truth models obtained from a LIDAR scanner.
3D Reconstruction of Indoor Scenes Based on Feature and Graph Optimization
Venue: 2016 International Conference on Virtual Reality and Visualization (ICVRV)

In this paper, we propose an approach of visual SLAM (Simultaneous localization and mapping) system, in which we build 3D scene models and estimate the camera poses at the same time. We detect SURF feature points from RGB images and use their relevant depth data to build 3D correspondences. With these correspondences, we align consecutive frames together using RANSAC, while ICP is performed when RANSAC fails. Keyframes are selected based on visual overlap between current frame and the latest keyframe. Furthermore, we detect loop closures between current keyframe and selected candidates of keyframes. Among these candidates, we perform a radius search to further prune the search space. With both sequential constraints and loop closure constraints, a pose graph is created and optimized using a robust global optimizer based on line processes.

Entre logique de production et de preservation l'evolution de l'information environnementale dans les domaines de l'eau et de la foret

La gouvernance de l'environnement depend de la maniere dont les acteurs se representent l'evolution des milieux et des ressources naturelles. Dans ce contexte, l'information environnementale peut constituer un appui pour justifier ou remettre en cause des modes de gestion. Quand elle est produite dans ce but, l'information est un instrument d'action publique qui vehicule elle meme certains cadrages, plus ou moins favorables a des logiques de production ou de preservation. Cet article s'interroge sur le lien entre l'usage de certains indicateurs pour l'action publique et la logique de production ou de preservation qui motive cette action. En retracant l'histoire de la regulation dans les secteurs hydrauliques et forestiers en France, nous montrons qu'il n'y a pas d'equivalence entre l'usage d'indicateurs ecologiques et la logique de preservation. Dans le domaine forestier, l'information sur les milieux a plutot servi les logiques sylvicoles et elle est principalement produite par les acteurs du secteur qui cherchent a mieux valoriser le bois. Dans le domaine de l'eau, l'information ecologique a ete un appui pour des acteurs qui denoncaient les exces d'une logique productive centree uniquement sur la ressource.
Service quality and price perception of service: Influence on word of mouth and revisit intention

Drawing on an overarching framework of marketing theory, this study develops and tests an integrated model of service quality that explicates the affective mechanisms through which service quality is associated with price perception of service (e.g. monetary price and behaviour price) word of mouth (WOM) and revisit intention. In a sample of 484 low cost airline passengers, we found service quality to be related to increased price perception of service as a result of increasing passengers' WOM, which also creates success in this regard by increasing their revisit intention. Moreover, it is not surprising that there was a positive relationship between service quality and WOM mediated by perceived value of monetary price. The theoretical and empirical implications of these results are discussed.
Path Analysis for the Halo Effect of Touch Sensations of Robots on Their Personality Impressions
Venue: ICSR

Physical human robot interaction plays an important role in social robotics, and touch is one of the key factors that influences human's impression of robots. However, very few studies have explored different conditions, and therefore, few systematic results have been obtained. As the first step toward addressing this issue, we studied the types of impressions of robot personality that humans may experience when they touch a soft part of a robot. In the study, the left forearm of a child like android robot "Affetto" was exposed; this forearm was made of silicone rubber and can be replaced with one of other three forearms providing different sensations of hardness upon touching. Participants were asked to touch the robot's forearm and to fill evaluation questionnaires on 19 touch sensations and 46 personality impressions under each of four conditions with different forearms. Four impression factors for touch sensations and three for personality impressions were extracted from the evaluation scores by the factor analysis method. The causal relationships between these factors were analyzed by the path analysis method. Several significant causal relationships were found, for example, between preferable touch sensations and likable personality impressions. The results will help design robots' personality impression by designing touch sensations more systematically.
ADAPTION OF THE LUCI FRAMEWORK TO ACCOUNT FOR DETAILED FARM MANAGEMENT A CASE STUDY EXPLORING POTENTIAL FOR NUTRIENT MITIGATION USING DATA FROM THE SOUTHLAND DEMONSTRATION FARM

This paper discusses recent progress in adapting the Land Utilisation and Capability Indicator (LUCI) framework to take account of the impact of detailed farm management on water, sediment and nutrient delivery to waterways. LUCI is a land management decision support framework which examines the impact of current and potential interventions on a variety of outcomes, including flood mitigation, water supply, greenhouse gas emissions, biodiversity, erosion, sediment and nutrient delivery to waterways, and agricultural production. It searches for "win win" solutions and cost effective, targeted mitigation options from sub field level to landscape and/or national scale simultaneously. It is therefore ideally placed to assist with decision making across multiple scales, such as informing the current debates about how best to implement nutrient regulation at farm, catchment and regional scales. However, past applications of LUCI have inferred land management from nationally available land cover categorisations, so historically it lacked the capacity to discriminate between differences in more detailed management (tillage information, type of irrigation system, stocking numbers and type, etc. Recently a collaboration with Ravensdown Limited has commenced. LUCI is being further developed within New Zealand to take in a range of more detailed management information, which can be entered directly to LUCI or easily integrated via an OVERSEER farm file. It is anticipated that this enhanced ability, combined with the framework's existing capacity to support multi scale decision making, will provide a decision support tool to New Zealand's farming community that complements OVERSEER and other available support tools. Example output and ongoing "validation" of LUCI's performance simulating nutrient loads and concentrations at the farm scale are presented using data from the Southland Demonstration Farm.
Effect of Music therapy on Labor Pain among Women in Active Labor Admitted in Tertiary Care Hospital Kochi

The pain associated with birth of baby is perceived severe, unpleasant and traumatizing by the women. It is an individualized phenomenon with both sensory and emotional elements. Labour pain arises from distension of the lower uterine segment and cervical dilatation. Anxiety and pain are closely interrelated with each other. Providing comfort to the women in labour is still a challenge for the nurse midwives. The present study intends to assess the effect of music therapy on labour pain and anxiety among women in first stage of labour in a tertiary care hospital kochi, India.
Effect of Music Therapy on Serum Cortisol in Primigravida in Active Labour

Unrelieved labour pain can result in exaggerated stress response and can have an adverse effect on the physiologic status of women. 'Medicinal music' is a growing area of research and is an effective intervention across many medical problems. This research is an effort to study the effects of music therapy on the stress experienced by the labouring women.  To determine the effect of music therapy on serum cortisol in primigravida in active labour.  In this study 100 primigravida women in active labour were randomly divided into music group (n=50) and control group (n=50) The women in the music group received 3 music therapy sessions starting early in the active phase of labour. Serum cortisol was estimated to measure the stress levels in the labouring women. Data obtained was analyzed using descriptive and inferential statistics  Student t test analyses showed that there was no significant difference between both the groups in serum cortisol at pre test [t=0.08, p 0.05] Whereas, the group differences after the music therapy sessions indicated that the music group had significant lower serum cortisol levels compared to the control group [t 7.46, p .05]  Music therapy is effective in reducing stress levels in the women during active labour.
Survey on Plastic Usage among the Teenagers of Alappuzha Town, Kerala

The survey was done to analyze the usage of plastic among the teenagers of Alappuzha town. College and school students as well as some of their neighbours were selected as the sample population. The sample population belonged to three age groups i.e. 15 17, 19 21 and 40 50, majority being teenagers i.e. the first two groups, comprising 91% of the total population. It is evident from the survey that without stringent control measures/ban from the side of government, the unhealthy usage of plastic as well as the pollution of environment by plastic waste would increase alarmingly. Though 73.5% of the surveyed subjects are of the opinion that plastic should be completely banned and 77% say they are ready to be involved in an initiative against plastic pollution, 92% disagree to carry a plastic bag in hand to shop so that it could be reused to maximum, 37% still prefer to use plastic carry bags instead of cloth/paper bags, 42% has adopted burning as a method of disposing plastic carry bags, 14% use more than six plastic carry bags each day, and 75% carry drinking water in plastic bottles. 51% of the people had never heard about Bisphenol A, a chemical that leaks from plastic. Survey shows that awareness given though education is not enough to equip students to take deterrent actions that favour the conservation of the environment instead of favouring ones comfort and convenience.
Validation of MODIS Aerosol Optical Depth Retrieval over Mountains in Central China Based on a Sun Sky Radiometer Site of SONET
Venue: Remote. Sens.

The 3 km Dark Target (DT) aerosol optical depth (AOD) products, 10 km DT and Deep Blue (DB) AOD products from the Collection 6 (C6) product data of Moderate Resolution Imaging Spectroradiometer (MODIS) are compared with Sun sky Radiometer Network (SONET) measurements at Song Mountain in central China, where ground based remote sensing measurements of aerosol properties are still very limited. The seasonal variations of AODs are significant in the Song Mountain region, with higher AODs in spring and summer and lower AODs in autumn and winter. Annual mean AODs (0.55 um) vary in the range of 0.5 0.7, which indicates particle matter (PM) pollutions in this mountain region. Validation against one year ground based measurements shows that AOD retrievals from the MODIS onboard Aqua satellite are better than those from the Terra satellite in Song Mountain. The 3 km and 10 km AODs from DT algorithms are comparable over this region, while the AOD accuracy of DB algorithm is relatively lower. However, the spatial coverage of DB products is higher than that of 10 km DT products. Moreover, the optical and microphysical characteristics of aerosols at Song Mountain are analyzed on the basis of SONET observations. It suggests that coarse mode aerosol particles dominate in spring, and fine mode particles dominate in summer. The aerosol property models are also established and compared to aerosol types used by MODIS algorithm.
SPME as a promising tool in translational medicine and drug discovery: From bench to bedside.
Venue: Journal of pharmaceutical and biomedical analysis

Solid phase microextraction (SPME) is a technology where a small amount of an extracting phase dispersed on a solid support is exposed to the sample for a well defined period of time. The open bed geometry and biocompatibility of the materials used for manufacturing of the devices makes it very convenient tool for direct extraction from complex biological matrices. The flexibility of the formats permits tailoring the method according the needs of the particular application. Number of studies concerning monitoring of drugs and their metabolites, analysis of metabolome of volatile as well as non volatile compounds, determination of ligand protein binding, permeability and compound toxicity was already reported. All these applications were performed in different matrices including biological fluids and tissues, cell cultures, and in living animals. The low invasiveness of in vivo SPME, ability of using very small sample volumes and analysis of cell cultures permits to address the rule of 3R, which is currently acknowledged ethical standard in R&D labs. In the current review systematic evaluation of the applicability of SPME to studies required to be conduct at different stages of drug discovery and development and translational medicine is presented. The advantages and challenges are discussed based on the examples directly showing given experimental design or on the studies, which could be translated to the models routinely used in drug development process.
Translational aspects in targeting the stromal tumour microenvironment: From bench to bedside
Venue: New horizons in translational medicine

Solid tumours comprise, not only malignant cells but also a variety of stromal cells and extracellular matrix proteins. These components interact via an array of signalling pathways to create an adaptable network that may act to promote or suppress cancer progression. To date, the majority of anti tumour chemotherapeutic agents have principally sought to target the cancer cell. Consequently, resistance develops because of clonal evolution, as a result of selection pressure during tumour expansion. The concept of activating or inhibiting other cell types within the tumour microenvironment is relatively novel and has the advantage of targeting cells which are genetically stable and less likely to develop resistance. This review outlines key players in the stromal tumour microenvironment and discusses potential targeting strategies that may offer therapeutic benefit.  Benchside The tumour stroma consists of mesenchymal, immune and vascular cells housed in an extracellular matrix. Stromal cells and extracellular matrix proteins represent genetically stable targets which can be exploited in cancer treatment. Numerous in vitro and animal studies support the concept of stromal directed treatment. Bedside Several therapeutic strategies have been developed or repurposed to target the stroma. The anti angiogenic agent bevacizumab was one of the first specific stromal targeting agents to be licensed for cancer treatment over a decade ago. More recently, immune modulation of the stroma has become a hugely successful strategy, with novel drugs such as checkpoint inhibitors set to revolutionise cancer treatment. Governments Funding bodies should continue to acknowledge the pivotal role that the stroma plays in cancer progression, in parallel with cancer cell itself. Undoubtedly, the most successful treatment regimens of the future will address both the "seed" and the "soil"
A Novel, Spatiotemporally Explicit Ecological Economic Modeling Procedure for the Design of Cost Effective Agri Environment Schemes to Conserve Biodiversity

Agri environment schemes (AES) compensate farmers for land use measures that are costly to them but beneficial to biodiversity and the environment. We present an ecological economic modeling procedure for the design of cost effective AES to conserve grassland biodiversity, which is applicable to large areas, covers many endangered species and grassland types, and includes several hundred different types of mowing regimes, grazing regimes, and combinations of mowing and grazing regimes as land use measures. The modeling procedure also accounts for the spatial variations in the land use measures' costs and in the effects on species and grassland types. The procedure's main novelty is that it considers variations of the costs and impacts on species and grassland types that arise from different timings of the land use measures. Considering the spatial and the temporal dimension of land use measures makes the modeling procedure spatiotemporally explicit. We demonstrate the power of the modeling procedure by evaluating an existing grassland AES in Saxony, Germany, and identify substantial improvements in terms of cost effectiveness.
