Demo Abstract: Smart City: A Real-Time Environmental Monitoring System on Green Roof

The research on the green roof is of great importance in the field of urban beautification and improving ecological effect. According to the previous research, plants have shown a significant impact on the absorption of PM2.5. Therefore, it is justified that the appropriate planting design or some particular combinations of plants can be considered as a solution, dealing with the urban fine particulate matter (PM2.5). This paper presented a work in progress on developing wireless sensor networks (WSN) system based on a prototype wind tunnel, which is used for the simulation of the green roof. Several data collection processes are handled by this system, where the concentration of PM2.5, wind speed, temperature & relative humidity are obtained and stored in the database simultaneously. Additionally, users are able to real-timely define their commands in details, controlling the sensor's height through a GUI on the website. Experimental and simulation results and measurements have verified the validity of the wind tunnel module as well as the reliability of the sensor network. The system can be operated on thousands of devices when the packet delay maintained in a low level.
Erratum to “Physiological Effects of Smoke Exposure on Deciduous and Conifer Tree Species”

Smoke from forest fires can persist in the environment for weeks and while there is a substantial amount of literature examining the effects of smoke exposure on seed germination, the effects of smoke on leaf function are nearly uninvestigated. The objective of this study was to compare growth and primary and secondary metabolic responses of deciduous angiosperm and evergreen conifer tree species to short smoke exposure. Twenty minutes of smoke exposure resulted in a greater than 50% reduction in photosynthetic capacity in five of the six species we examined. Impairment of photosynthesis in response to smoke was a function of reductions in stomatal conductance and biochemical limitations. In general, deciduous angiosperm species showed a greater sensitivity than evergreen conifers. While there were significant decreases in photosynthesis and stomatal conductance, smoke had no significant effect on growth or secondary defense compound production in any of the tree species examined.
CFD-based iterative methodology for modeling natural convection in microelectronic packages

In order to predict and manage the thermal behavior of microelectronic packages cooled principally by natural convection, a two-way coupling method was developed between a accurate conduction model and a computational fluid dynamics (CFD) simulation. An iterative solution loop was performed by applying as a boundary condition the local convection coefficients obtained from the CFD to the conduction model, and the temperature field at the solid-fluid interface obtained from the solid conduction model to CFD simulation. For the first iteration, the conduction heat transfer was solved by considering an initial guess of a uniform convection coefficient (e.g. from empirical formulas) for each solid-fluid interface. The procedure was repeated until the convergence of the solution was reached. The comparison between the total convection coefficients including the radiation obtained with the CFD iterative procedure and those from the conventional empirical methods showed important differences, thus demonstrating the usefulness of the CFD approach to obtain accurate thermal results. The numerical results were compared to measurements from a test vehicle, carried out under the natural convection Jedec JESD51 standards in a still air chamber. Radiation plays an important role in heat transfer in this setting because of the large temperature difference between the walls of the box and the test vehicle. The junction temperatures obtained with the numerical simulation for different operating powers were in good agreement with the experimental measurements, with an error of less than 1°C, showing that the proposed methodology allows the accurate simulation of the natural heat transfer for microelectronic packages mounted on PCB in the horizontal orientation.
Postpartum maternal mental health is associated with cognitive development of HIV-exposed infants in Zimbabwe: a cross-sectional study

ABSTRACT This study examines the cognitive profiles of infants born to HIV positive mothers in Zimbabwe. Caregivers with HIV exposed infants delivered in 30 clinics in two areas of Zimbabwe were recruited to the study. Of the 574 study participants, 562 caregiver-infant dyads with a biological HIV +ve mother and infant aged 0–24 months were interviewed. All infants were tested by a trained administrator for cognitive development on the Mullen Scales of Early Learning (MSEL). The Edinburgh Postnatal Depression Scale and Parental Stress Index-Short Form were completed by the mothers together with infant and caregiver socioeconomic characteristics. Linear regression models were used to relate cognitive development scores to maternal stress scores, maternal depression scores and infant HIV status adjusting for infant and caregiver characteristics, as well as socioeconomic factors. Higher maternal depression scores were associated with lower overall infant cognitive scores (adjusted mean difference (aMD) = −0.28; CI 95%:−0.50 to −0.06; p = 0.01) and in the expressive language (aMD = −0.14; CI 95%:−0.27 to −0.01; p = 0.04), fine motor skills (aMD = −0.17; CI 95%: −0.33 to −0.01; p = 0.03), gross motor (aMD = −0.22; CI 95%:−0.40 to −0.04; p = 0.02), and visual reception (aMD = −0.22; CI 95%:−0.40 to −0.05; p = 0.01) domains. Higher maternal stress was associated with poorer overall infant cognitive scores (aMD = −0.11; CI 95%:−0.20 to −0.02; p = 0.02) and in the specific domains of expressive language (aMD = −0.07; CI 95%:−0.12 to −0.01; p = 0.01), gross motor skills (aMD = −0.12; CI 95%:−0.18 to −0.05; p < 0.01) and visual reception (aMD = −0.09; CI 95%:−0.16 to −0.02; p = 0.02). Comparisons between the small number of HIV positive infants (n = 16) and the HEU infants (n = 381) showed the latter to have higher mean gross motor scores (50.3 vs. 40.6; p = 0.01). There was no evidence of difference by HIV status in the other MSEL domains or overall mean cognitive scores. Our findings demonstrate the association between maternal mood and stress levels and child cognitive functioning, particularly in expressive language and visual reception development. Although cross sectional data cannot shed light on the direction of this association, the study suggests that interventions to address maternal stress and depression symptoms may prove to be beneficial.
Atmospheric Chemistry Experiment (ACE) measurements of elevated Southern Hemisphere upper tropospheric CO, C2H6, HCN, and C2H2 mixing ratios from biomass burning emissions and long‐range transport

Infrared Fourier transform spectra recorded at 0.02 cm−1 resolution by the Atmospheric Chemistry Experiment (ACE) show elevated levels of the relatively long‐lived biomass burning products CO, C2H6, HCN, and C2H2 in the upper troposphere and lower stratosphere at 15°S–45°S latitude from 30 September to 3 November 2004. Mixing ratios up to 260 ppbv (10−9 per unit volume) for CO, 1470 pptv (10−12 per unit volume) for HCN, and 1.67 ppbv for C2H6 are observed in the upper troposphere and their variations are highly correlated reflecting their similar lifetimes and emission origin. Back trajectory calculations and maps of fire distributions for the time period indicate the elevated levels likely originated from regions of tropical fire emissions in South America or Africa with cases identified with elevated emissions reaching close to the lower stratosphere.
Ex vivo diffusion MRI of the human brain: Technical challenges and recent advances

This review discusses ex vivo diffusion magnetic resonance imaging (dMRI) as an important research tool for neuroanatomical investigations and the validation of in vivo dMRI techniques, with a focus on the human brain. We review the challenges posed by the properties of post‐mortem tissue, and discuss state‐of‐the‐art tissue preparation methods and recent advances in pulse sequences and acquisition techniques to tackle these. We then review recent ex vivo dMRI studies of the human brain, highlighting the validation of white matter orientation estimates and the atlasing and mapping of large subcortical structures. We also give particular emphasis to the delineation of layered gray matter structure with ex vivo dMRI, as this application illustrates the strength of its mesoscale resolution over large fields of view. We end with a discussion and outlook on future and potential directions of the field.
Decision-making in a storm of discontent

Regulation of pesticides such as glyphosate needs to include societal assessment On 12 December 2017, the European Commission reapproved the use of glyphosate, the world's most widely used active ingredient in herbicides and possibly the most heavily debated plant protection product since DDT (dichlorodiphenyltrichloroethane), for another 5-year period (1). Less than a week later, the U.S. Environmental Protection Agency (EPA) released its draft risk assessment for glyphosate, which concluded that human health risk levels associated with glyphosate exposure from food, drinking water, and residential sources are below the agency's levels of concern (2). Both in Europe and the United States, these decisions faced a storm of public discontent owing to concerns about the possible risks of chemical exposures and the role of large multinational companies. We argue that a broader societal assessment should be included in the decision-making process on pesticide registration.
Structured Local Optima in Sparse Blind Deconvolution

Blind deconvolution is a ubiquitous problem aiming to recover a convolution kernel <inline-formula> <tex-math notation="LaTeX">$\boldsymbol a_{0}\in \mathbb R ^{k}$ </tex-math></inline-formula> and an activation signal <inline-formula> <tex-math notation="LaTeX">$\boldsymbol x_{0}\in \mathbb R ^{m}$ </tex-math></inline-formula> from their convolution <inline-formula> <tex-math notation="LaTeX">$\boldsymbol y\in \mathbb R ^{m}$ </tex-math></inline-formula>. Unfortunately, this is an ill-posed problem in general. This paper focuses on the <italic>short and sparse</italic> blind deconvolution problem, where the convolution kernel is short (<inline-formula> <tex-math notation="LaTeX">$k\ll m$ </tex-math></inline-formula>) and the activation signal is sparsely and randomly supported (<inline-formula> <tex-math notation="LaTeX">$\left \|{ \boldsymbol x_{0} }\right \|_{0}\ll m$ </tex-math></inline-formula>). This variant captures the structure of the convolutional signals in several important application scenarios. In this paper, we normalize the convolution kernel to have unit Frobenius norm and then cast the blind deconvolution problem as a nonconvex optimization problem over the kernel sphere. We demonstrate that (i) in a certain region of the sphere, every local optimum is close to some shift truncation of the ground truth, and (ii) for a generic unit kernel <inline-formula> <tex-math notation="LaTeX">$\boldsymbol a_{0}$ </tex-math></inline-formula>, when the sparsity of activation signal satisfies <inline-formula> <tex-math notation="LaTeX">$\theta \lesssim k^{-2/3}$ </tex-math></inline-formula> and number of measurements <inline-formula> <tex-math notation="LaTeX">$m\gtrsim \mathop {\mathrm {poly}}\nolimits \left ({k }\right) $ </tex-math></inline-formula>, the proposed initialization method together with a descent algorithm which escapes strict saddle points recovers some shift truncation of the ground truth kernel.
Incidence of influenza A(H3N2) virus infections in Hong Kong in a longitudinal sero-epidemiological study, 2009-2015

Background Many serologic studies were done during and after the 2009 influenza pandemic, to estimate the cumulative incidence of influenza A(H1N1)pdm09 virus infections, but there are few comparative estimates of the incidence of influenza A(H3N2) virus infections during epidemics. Methods We conducted a longitudinal serologic study in Hong Kong. We collected sera annually and tested samples from 2009–13 by HAI against the A/Perth/16/2009(H3N2) virus, and samples from 2013–15 against the A/Victoria/361/2011(H3N2) virus using the hemagglutination inhibition (HAI) assay. We estimated the cumulative incidence of infections based on 4-fold or greater rises in HAI titers in consecutive sera. Results There were four major H3N2 epidemics: (1) Aug-Oct 2010; (2) Mar-Jun 2012; (3) Jul-Oct 2013; and (4) Jun-Jul 2014. Between 516 and 619 relevant pairs of sera were available for each epidemic. We estimated that 9%, 19%, 7% and 7% of the population were infected in each epidemic, respectively, with higher incidence in children in epidemics 1 and 4. Conclusions We found that re-infections in each of the four H3N2 epidemics that occurred from 2010 through 2014 were rare. The largest H3N2 epidemic occurred with the lowest level of pre-epidemic immunity.
QUEM VEM LÁ?! METALINGUAGEM, AGONISMO E HIBRIDAÇÃO CULTURAL COMO MARCAS DIFUSAS DE UM PROCESSO CRIATIVO

Eu nasci no ano de 2013. Todo compositor nasce junto com a sua musica. Quem vem la? e fruto de um esforco de imaginacao sobre o nascimento. Nomeadamente, o nascimento do autor, da obra, ela propria, e tambem o nascimento de um pelas entranhas do outro. A musica e o esboco de um roteiro fantastico que inclui, em seu nucleo, o criador (reflexivo por natureza) virando a sua propria pele ao avesso, renascendo-se a si proprio, na medida em que pare, tambem, a criatura.

University of Florida 2016 Slot Filler Validation system

In this paper we present the University of Florida 2016 Slot filler Validation (SFV) system. This is an on going work that started in the previous SFV evaluation where we presented a semi-supervised ensemble learning approach to aggregate the results from multiple slot fillers from the Cold Start track. In 2016 we introduce two major features. First, given the computational complexity of jointly reasoning over the complete set of input KBs, we present a query driven approach that reasons only over the set of candidate answers to a specific query. Our query driven approach also allow our system to be more selective answering 1-hop queries by evaluating only presumably correct answers from its corresponding 0-hop part. The second feature, is an extra layer of ensemble that combines signals from three types of uncertainty: (1) from the extractors, (2) from source documents and (3) from users beliefs. In addition to the new main features, we also used a distance metric to partially disambiguate shallow entity names from different slot filler runs.
Realizing the Global Edge Cloud

The recent trend toward application hosting in large data centers should and will be counterbalanced by a ubiquitous edge cloud with deeply programmable networking. The Internet to date has been dominated by sending data to programs and people; the next Internet will be dominated by managing data and the connections to people generating and needing the data. In this article, we describe why the Internet is on the cusp of this transition, two prototypes of this next Internet, PlanetLab [1] and the Global Environment for Network Innovations (GENI) [2], and the architectural concepts that emerge from them. We describe the next step: the viral stage, GENI-as-a- Service.
Comparison of Dental Panoramic Radiography and CBCT for Measuring Vertical Bone Height in Different Horizontal Locations of Posterior Mandibular Alveolar Process

Statement of the Problem: Accurate measurement of the available bone height is an essential step in the pre-surgical phase of dental implantation. Panoramic radiography is a unique technique in the pre-surgical phase of dental implantations because of its low cost, relatively low-dose, and availability. Purpose: This article aimed to assess the reliability of dental panoramic radiographs in the accurate measurement of the vertical bone height with respect to the horizontal location of the alveolar crest. Materials and Method: 132 cone-beam computed tomography (CBCT) of the edentulous mandibular molar area and dental panoramic radiograph of 508 patients were selected. Exclusion criteria were bone abnormalities and detectable ideal information on each modality. The alveolar ridge morphology was categorized into 7 types according to the relative horizontal location of the alveolar crest to the mandibular canal based on CBCT findings. The available bone height (ABH) was defined as the distance between the upper border of the mandibular canal and alveolar crest. One oral radiologist and one oral surgeon measured the available bone height twice on each modality with a 7-dayinterval. Results: We found a significant correlation between dental panoramic radiographs and cone-beam computed tomography values (ICC=0.992, p< 0.001). A positive correlation between the horizontal distance of the alveolar crest to the mandibular canal and measured differences between two radiographic modalities had been found (r=0.755, p< 0.001). For each single unit of increase in the horizontal distance of the alveolar crest to the mandibular canal, dental panoramic radiographs showed 0.87 unit of overestimation (p< 0.001). Conclusion: Dental panoramic radiographs can be employed safely in the pre-surgical phase of dental implantation in posterior alveolus of mandible, especially in routine and simple cases.
DTC of three-level inverter fed brushless DC motor drives with torque ripple reduction

The paper deals with the synthesis and performance analysis of the direct torque control (DTC) strategy dedicated to three-level NPC inverter (B12) fed brushless DC (BLDC) motor drives. The principle of operation of the BLDC motor fed by the B12-inverter is firstly presented with emphasis on the two-phase conduction mode and the three-phase conduction one. The DTC strategy is treated considering three different schemes, namely: (i) DTCi strategy inspired from the one developed by Takahashi in induction motor drives, (ii) DTC2 strategy that considers a vector selection table simply-reduced to the torque control with a two-phase conduction mode during sectors operation, and (iii) DTC3 strategy that eliminates the torque dips penalizing DTC2 during sector-to-sector commutations by considering the three-phase conduction mode. Simulation results, carried out considering low and high reference motor speeds, proves the high performance exhibited by the proposed DTC3 strategy.
Grain size tuning of nanocrystalline chemical vapor deposited diamond by continuous electrical bias growth: Experimental and theoretical study

In this work, a detailed structural and spectroscopic study of nanocrystalline diamond (NCD) thin films grown by a continuous bias assisted CVD growth technique is reported. This technique allows the tuning of grain size and phase purity in the deposited material. The crystalline properties of the films are characterized by SEM, TEM, EELS, and Raman spectroscopy. A clear improvement of the crystalline structure of the nanograined diamond film is observed for low negative bias voltages, while high bias voltages lead to thin films consisting of diamond grains of only ∼10 nm nanometer in size, showing remarkable similarities with so‐called ultrananocrystalline diamond. These layers arecharacterized by an increasing amount of sp2‐bonded carbon content of the matrix in which the diamond grains are embedded. Classical molecular dynamics simulations support the observed experimental data, giving insight in the underlying mechanism for the observed increase in deposition rate with bias voltage. Furthermore, a high atomic concentration of hydrogen has been determined in these films. Finally, Raman scattering analyses confirm that the Raman line observed at ∼1150 cm−1 cannot be attributed to trans‐poly‐acetylene, which continues to be reported in literature, reassigning it to a deformation mode of CHx bonds in NCD.
Bioenergetic modulators hamper cancer cell viability and enhance response to chemotherapy

Gliomas are characterized by a marked glycolytic metabolism with a consequent production of massive amounts of lactate, even in the presence of normal levels of oxygen, associated to increased invasion capacity and to higher resistance to conventional treatment. This work aimed to understand how the metabolic modulation can influence tumour aggressive features and its potential to be used as complementary therapy. We assessed the effect of bioenergetic modulators (BMs) targeting different metabolic pathways in glioma cell characteristics. The in vivo effect of BMs was evaluated using the chicken chorioallantoic membrane model. Additionally, the effect of pre‐treatment with BMs in the response to the antitumour drug temozolomide (TMZ) was analysed in vitro. Cell treatment with the BMs induced a decrease in cell viability and in migratory/invasion abilities, as well as modifications in metabolic parameters (glucose, lactate and ATP) and increased the cytotoxicity of the conventional drug TMZ. Furthermore, all BMs decreased the tumour growth and the number of blood vessels in an in vivo model. Our results demonstrate that metabolic modulation has the potential to be used as therapy to decrease the aggressiveness of the tumours or to be combined with conventional drugs used in glioma treatment.
Maternal Circulating Vitamin Status and Colostrum Vitamin Composition in Healthy Lactating Women—A Systematic Approach

Colostrum is the first ingested sole nutritional source for the newborn infant. The vitamin profile of colostrum depends on the maternal vitamin status, which in turn is influenced by diet and lifestyle. Yet, the relationship between maternal vitamin status and colostrum vitamin composition has not been systematically reviewed. This review was conducted with the aim to generate a comprehensive overview on the relationship between maternal serum (plasma) vitamin concentration and corresponding colostrum composition. Three electronic databases, Embase (Ovid), Medline (Ovid), and Cochrane, were systematically searched based on predefined inclusion and exclusion criteria. Finally, a total of 11 eligible publications were included that examined the vitamins A, C, D, E, and K in both biological fluids. Maternal vitamin A, D, E, and K blood levels were unrelated to colostrum content of the respective vitamins, and serum vitamin A was inversely correlated with colostrum vitamin E. Colostrum versus maternal serum vitamins were higher for vitamins A, C, and K, lower for vitamin D, and divergent results were reported for vitamin E levels. Colostrum appears typically enriched in vitamin A, C, and K compared to maternal serum, possibly indicative of active mammary gland transport mechanisms. Inter-individual and inter-study high variability in colostrum’s vitamin content endorses its sensitivity to external factors.
A Dual Quaternion Feedback Linearized Approach for Maneuver Regulation of Rigid Bodies

The adoption of the dual quaternion formalism to represent the pose (position and orientation) of a rigid body allows to design a single controller to regulate both its position and its attitude. In this letter, we adopt such a pose representation to develop an exponentially stable maneuver regulation control law, ensuring robust path following in the presence of disturbances. The designed solution relies on the feedback linearized model of the dual quaternion based dynamics of the rigid body. Numerical results confirm the effectiveness of the proposed maneuver regulation approach when compared with trajectory tracking in a noisy scenario.
