Vehicle detection in urban point clouds with orthogonal view convolutional neural network
Venue: 2016 IEEE International Conference on Image Processing (ICIP)

In this paper, we aim at detecting vehicles from the point clouds scanned from the urban area. Our detection method consists of a segmentation stage and a classification stage. Prior knowledge for vehicles and urban environment is utilized to help the detection process. Specifically, we incorporate curb detection and removal in the segmentation stage. Moreover, our approach is able to estimate the orientation of the candidates and use it to handle the difficult cases such as the vehicles in the parking lot. In order to distinguish the vehicles from other segments among the 3D point cloud candidates, we develop three architectures of the orthogonal view CNN, which are based on the orthogonal view projections of the candidates. Detailed evaluations and comparisons are performed on a challenging point cloud dataset of urban area.
Point cloud labeling using 3D Convolutional Neural Network
Venue: 2016 23rd International Conference on Pattern Recognition (ICPR)

In this paper, we tackle the labeling problem for 3D point clouds. We introduce a 3D point cloud labeling scheme based on 3D Convolutional Neural Network. Our approach minimizes the prior knowledge of the labeling problem and does not require a segmentation step or hand crafted features as most previous approaches did. Particularly, we present solutions for large data handling during the training and testing process. Experiments performed on the urban point cloud dataset containing 7 categories of objects show the robustness of our approach.
Development and validation of the Japanese version of Primary Care Assessment Tool.
Venue: Family practice

Tools for assessing quality of primary care from patient experience have never previously existed in Japan.  The aim of this study was to develop the Japanese version of Primary Care Assessment Tool (JPCAT) and to examine the validity of this tool in the assessment of the quality of primary care from patient experience in Japan.  We used a cross sectional mail survey to test the validity and reliability of JPCAT. The questionnaire was sent to 1100 residents, 40 75 years of age, who were randomly selected from a basic resident register in Kita City, Tokyo, Japan. We examined internal consistency included Cronbach's alpha, exploratory factor analysis, multi trait analysis and correlation between overall user satisfaction scores and JPCAT total scores.  The tool was developed using responses from 204 residents, out of a total of 402 participants in the survey (50.7% who had the usual sources of care. A 29 item JPCAT was constructed to include six multi item subscales, representing each of the five primary care principles (first contact, longitudinality, comprehensiveness, coordination and community orientation) All of the multi item scales achieved good internal consistency, item total correlations and construct validity. The overall Cronbach's alpha coefficient was 0.90. The Spearman correlation coefficient between the JPCAT total score and the overall user satisfaction was 0.58. Scaling assumptions tests were well satisfied. The full range of possible scores was observed for all scales except the longitudinality domain.  We developed JPCAT and examined its validity and reliability in assessing the core principles of primary care in Japan. This tool could be used for health service research in primary care.
Validation of the STRATIFY Falls Risk Assessment Tool in a Japanese Acute Care Hospital Setting.
Venue: Global journal of health science

Patient falls are the most frequent adverse events that occur in a hospital. Prevention of inpatient falls is performed by a strategy to target patients at high risk for falls determined by a falls risk assessment system such as the STRATIFY tool. However, the performance of the STRATIFY tool in a Japanese hospital setting has not been determined. We tried to verify the performance of the STRATIFY tool for predicting falls in acutely hospitalized patients in Japan by a multi center study. A total of 113,413 patients admitted to four acute cares national university hospitals during the period from April 2010 to March 2012 were studied. Inpatient falls per 1,000 patient days varied from 1.42 to 2.92 in the four hospitals. The STRATIFY score was calculated on the basis of data extracted electronically from the hospital information system. Although the distribution of STRATIFY scores differed significantly among the four hospitals, logistic regression analysis and survival analysis showed that the proportion of high risk patients who fell was significantly larger than the proportion of low risk patients in all of the four hospitals. The odds ratio and hazard ratio for high risk patients versus low risk patients were 2.5 to 4.3 (combined estimate, 3.9 (95% confidence interval (95% CI) 2.1 to 7.6) and 1.8 to 5.1 (combined estimate, 3.1 (95% CI, 2.1 to 4.6) respectively. The results suggest that the STRATIFY tool can be used as a screening tool to detect patients at high risk for falls in a Japanese acute care setting as used commonly in other countries.

Sickle cell anemia mice develop a unique cardiomyopathy with restrictive physiology
Venue: Proceedings of the National Academy of Sciences

Sickle cell anemia (SCA) is a common monogenic disorder associated with significant morbidity and mortality and a high incidence of unexplained sudden death in young adults. With the prevention of infections, there is an increasing appreciation for cardiopulmonary complications and a cardiac phenotype that cannot be solely attributed to chronic anemia. We used mouse models of SCA and iron deficient anemia to show distinct functional, pathological, ultrastructural, and molecular cardiac features causing a unique restrictive cardiomyopathy in SCA that predisposed the myocardium to electrophysiological abnormalities and sudden death. This is a comprehensive longitudinal analysis in preclinical mouse models that unifies the previously reported diverse cardiac phenotypes in SCA, and opens new avenues for early diagnostics and targeted therapies for human SCA related cardiac disease. Cardiopulmonary complications are the leading cause of mortality in sickle cell anemia (SCA) Elevated tricuspid regurgitant jet velocity, pulmonary hypertension, diastolic, and autonomic dysfunction have all been described, but a unifying pathophysiology and mechanism explaining the poor prognosis and propensity to sudden death has been elusive. Herein, SCA mice underwent a longitudinal comprehensive cardiac analysis, combining state of the art cardiac imaging with electrocardiography, histopathology, and molecular analysis to determine the basis of cardiac dysfunction. We show that in SCA mice, anemia induced hyperdynamic physiology was gradually superimposed with restrictive physiology, characterized by progressive left atrial enlargement and diastolic dysfunction with preserved systolic function. This phenomenon was absent in WT mice with experimentally induced chronic anemia of similar degree and duration. Restrictive physiology was associated with microscopic cardiomyocyte loss and secondary fibrosis detectable as increased extracellular volume by cardiac MRI. Ultrastructural mitochondrial changes were consistent with severe chronic hypoxia/ischemia and sarcomere diastolic length was shortened. Transcriptome analysis revealed up regulation of genes involving angiogenesis, extracellular matrix, circadian rhythm, oxidative stress, and hypoxia, whereas ion channel transport and cardiac conduction were down regulated. Indeed, progressive corrected QT prolongation, arrhythmias, and ischemic changes were noted in SCA mice before sudden death. Sudden cardiac death is common in humans with restrictive cardiomyopathies and long QT syndromes. Our findings may thus provide a unifying cardiac pathophysiology that explains the reported cardiac abnormalities and sudden death seen in humans with SCA.
Tourism Destination Image

Although tourism destination image (TDI) has been extensively studied, the nature and scope of TDI remain vague. This study aims to address this conceptual problem from a modernist perspective. Forty five representative TDI definitions are analyzed, and a new definition is proposed by adopting a "seven step" procedure derived from definition theory in logic studies. Results show that (1) currently TDI is defined mainly as the mental/total impressions/perceptions held by tourists pertaining to a destination, (2) such definitions are quasi theoretical in type and created by roughly following the connotative definition technique, (3) the quality of these definitions is generally low, and (4) the new definition proposed in this study better captures the essence of TDI and considerably reduces TDI's internal and external vagueness. In defining a key tourism concept, this study has notable implications for advancing TDI research and defining tourism concepts more rigorously.
'Does it Really Affect Me? Tourism Destination Narratives, Destination Image, and the Intention to Visit: Examining the Moderating Effect of Narrative Transportation

The extent to which tourism destination marketing narratives with different themes influence readers by imaginatively 'transporting' them is quite varied. This study investigates the different degrees of influence such narratives have on destination image and the intention to visit, exploring how the intensity of readers' experiences of being transported by narratives with different themes can influence their intention to visit the places described. Our results reveal the extent to which different narrative themes affect destination image and significantly influence readers' intention to visit. The extent to which narratives with different themes make readers feel transported also has a significant moderating effect on their intention to visit.
Tourism Destination Image (TDI) Perception Within a Regional Winescape Context

This study conceptualizes the perception of a tourism destination image (TDI) in the process integrating multiple theories such as servicescape, place based, and destination perceptions. The research outlines the conceptualization of a wine TDI in the form of a regional winescape framework as perceived by visitors. The nature of the wine tourism product and experience requires that a research approach be developed that differs from the generic approaches used in mainstream TDI studies. A free form approach was used to integrate TDI perception, services marketing, servicescape, and place based marketing theories. The winescape construct is identified within a framework of eight dimensions for a well known Australian region. The most important winescape dimension is the natural beauty/geographical setting. The in state and out of state origin dynamic affects visitors' wine tourism behavior and perception of the region's winescape. For in state and out of state visitors, there are pronounced differences in their perception of the region's winescape dimensions. Increasing distance from the destination region is pivotal in the perception of the winescape dimensions and thus the TDI.
Medical tourism destination image formation process: A conceptual model

Perceived risks, travel motivations, and destination cognitive and affective image have been extensively studied in tourism literature, yet literature related to these variables in medical tourism literature is sparse. The concept argued in this article is founded on the decision making models used in tourism literature and drawing on work of prominent scholars in tourism. Findings of the literature review suggest that Medical Tourists' perceived risks about destination and travel motivations will have impact on the image of medical tourism destinations.
Wine tourism destination image on the web: a comparison between conveyed and perceived communication drivers

Assuming that actual or potential wine tourists may perceive the wine tourism destinations' image using as cognitive keys what has been communicated by both wine tourism destinations and travelling bloggers, the research aims at carrying out an analysis which: 1) suggests the identification of the main recurring themes and their importance in communicating the destination image; 2) highlights the [eventual] gap existing between what is communicated by the wine tourism destinations and what is transmitted by third party actors (in this case, by bloggers in their own blogs) The approach is innovative because: 1) the creation of a communicative and relational sphere of the image derives from techniques and instruments that stimulate conversations, taking advantage of the bi directional communication potentialities offered by the web; 2) it suggests an operational framework through which it is possible to identify the dimensions to decode the extracted information.
The split property for quantum field theories in flat and curved spacetimes

The split property expresses a strong form of independence of spacelike separated regions in algebraic quantum field theory. In Minkowski spacetime, it can be proved under hypotheses of nuclearity. An expository account is given of nuclearity and the split property, and connections are drawn to the theory of quantum energy inequalities. In addition, a recent proof of the split property for quantum field theory in curved spacetimes is outlined, emphasising the essential ideas.
Quantum field theory on curved spacetimes: Axiomatic framework and examples

In this review article, we want to expose a systematic development of quantum field theory on curved spacetimes. The leading principle is the emphasis on local properties. It turns out that this requires a reformulation of the QFT framework which also yields a new perspective for the theories on Minkowski space. The aim of the present work is to provide an almost self contained introduction into the framework, which should be accessible for both mathematical physicists and mathematicians.
An Analogue of the Coleman Mandula Theorem for Quantum Field Theory in Curved Spacetimes

The Coleman Mandula (CM) theorem states that the Poincare and internal symmetries of a Minkowski spacetime quantum field theory cannot combine nontrivially in an extended symmetry group. We establish an analogous result for quantum field theory in curved spacetimes, assuming local covariance, the timeslice property, a local dynamical form of Lorentz invariance, and additivity. Unlike the CM theorem, our result is valid in dimensions {n\geq 2}$n>=2 and for free or interacting theories. It is formulated for theories defined on a category of all globally hyperbolic spacetimes equipped with a global coframe, on which the restricted Lorentz group acts, and makes use of a general analysis of symmetries induced by the action of a group G on the category of spacetimes. Such symmetries are shown to be canonically associated with a cohomology class in the second degree nonabelian cohomology of G with coefficients in the global gauge group of the theory. Our main result proves that the cohomology class is trivial if G is the universal cover \mathcal{S}$S of the restricted Lorentz group. Among other consequences, it follows that the extended symmetry group is a direct product of the global gauge group and \mathcal{S}$S, all fields transform in multiplets of \mathcal{S}$S, fields of different spin do not mix under the extended group, and the occurrence of noninteger spin is controlled by the centre of the global gauge group. The general analysis is also applied to rigid scale covariance.

Idempotent Expansions for Continuous Time Stochastic Control
Venue: SIAM J. Control. Optim.

Max plus methods have previously been used to solve deterministic control problems. The methods are based on max plus (or min plus) expansions and can yield curse of dimensionality free numerical methods. In this paper, we explore min plus methods for continuous time stochastic control on a finite time horizon. We first approximate the original value function via time discretization. By generalizing the min plus distributive property to continuum spaces, we obtain an algorithm for recursive computation of the time discretized values, which we refer to as the idempotent distributed dynamic programming principle (IDDPP) Under the IDDPP, the value function at each step can be represented as an infimum of functions in a certain class. This is a min plus expansion for the value function. For the specific class of problems considered here, we see that the class can be taken as that consisting of the quadratic functions. A means for reducing the numbers of constituent quadratic functions is discussed.
WFI electronics and on board data processing
Venue: Astronomical Telescopes Instrumentation

The Wide Field Imager is one of two instruments on board the future ATHENA X ray observatory. Its main scientific objective is to perform a sky survey in the energy range of 0.2 keV up to 15 keV with an end of life spectral resolution (FWHM) better than 170 eV (at 7 keV) and a frame rate of at least 200 Hz. The field of view will be 40 arcmin squared wherefore a focal plane array with 4 large sensors each with a size of 512 times 512 pixels will be developed. Additionally, a fast detector with a size of 64 times 64 pixels and a frame rate of 12.5 kHz will be implemented in order to enhance the instrument with high count rate detection of bright sources. The data processing electronics within the WFI instrument is distributed over several subsystems: DEPFET sensors sensitive in the x ray energy regime and front end electronics are located inside the Camera Head. Data pre processing inside the Detector Electronics will be performed in an FPGA based frame processor. FPGA external memory will be used to store offset and noise maps wherefore memory controllers have to be developed. Fast read and write access to the maps combined with robustness against radiation damage (e.g. bit flips) has to be ensured by the frame processor design.
A history of the DNA repair and mutagenesis field: The discovery of base excision repair.
Venue: DNA repair

This article reviews the early history of the discovery of an DNA repair pathway designated as base excision repair (BER) since in contrast to the enzyme catalyzed removal of damaged bases from DNA as nucleotides [called nucleotide excision repair (NER) BER involves the removal of damaged or inappropriate bases, such as the presence of uracil instead of thymine, from DNA as free bases.
Measuring Latency Variation in the Internet
Venue: CoNEXT

We analyse two complementary datasets to quantify the latency variation experienced by internet end users: (i) a large scale active measurement dataset (from the Measurement Lab Network Diagnostic Tool) which shed light on long term trends and regional differences; and (ii) passive measurement data from an access aggregation link which is used to analyse the edge links closest to the user. The analysis shows that variation in latency is both common and of significant magnitude, with two thirds of samples exceeding 100, ms of variation. The variation is seen within single connections as well as between connections to the same client. The distribution of experienced latency variation is heavy tailed, with the most affected clients seeing an order of magnitude larger variation than the least affected. In addition, there are large differences between regions, both within and between continents. Despite consistent improvements in throughput, most regions show no reduction in latency variation over time, and in one region it even increases. We examine load induced queueing latency as a possible cause for the variation in latency and find that both datasets readily exhibit symptoms of queueing latency correlated with network load. Additionally, when this queueing latency does occur, it is of significant magnitude, more than 200\,ms in the median. This indicates that load induced queueing contributes significantly to the overall latency variation.
Measuring quality of service for mobile internet services
Venue: 2016 2nd International Conference on Science in Information Technology (ICSITech)

Quality of Service is an important thing in maintaining the performance of the service to the customer. Not only for marketing purposes, the quality of services can also bridge the gap between the promise given by the service provider and what the customers get. This study aims to get the quality of service for internet data usage of several mobile operators in the city Samarinda. The study was conducted using a mobile device and implemented in seven districts and four points in every district in the city of Samarinda. Measurements using the standard quality of TIPHON with some parameters such end to end delay, jitter, packet loss probability and throughput. From the measurement results, based on standard QoS TIPHON, the average value of packet loss are in the good category. Latency delay value is very high, above 400 ms, which is a bad category. Delay variation (jitter) of each ISP is different, with the average value of jitter is more than 50 ms. The measurement results show that the jitter at each site are in a bad category.
