Travel Location Sequence Recommendation From User’s Point of Interest

The major objective of any Travel Recommendation System is to recommend its users to visit the most suitable place in according to the selected location. We present this system of travel recommendation from the experiences of the previously visited users of that location. Apart from the existing systems, our approach not only limited to users traveling interest but also recommends a travel sequence. Our sys-tem also suggest best visiting time, most suitable season, preference of visiting the nearby places and traveling route to reach to your desired location. Here the user can create his friend list and can share his experience of visit to his friends. This user given experience is taken as a feedback by the system to update his recommendations.
Conceptual Combination with Prototype Concepts

This paper deals with how people combine simple, prototype concepts into complex ones; e.g., how people combine the prototypes for brown and apple so they can determine the typicality of objects in the conjunction brown apple . We first consider a proposal from fuzzy-set theory ( Zadeh, 1965 ), namely, that the typicality of an object in a conjunction is equal to the minimum of that object's typicality in the constituents (e.g., an object's typicality as a brown apple cannot exceed its typicality as a brown or as an apple ). We evaluated this “min rule” against the typicality ratings of naive subjects in two experiments. For each of numerous pictured objects, one group of subjects rated its typicality with respect to an adjective concept, a second group rated its typicality visa-vis a noun concept, and a third group rated its typicality with respect to the adjective-noun conjunction. In both studies, most objects were rated as more typical of the conjunction than of the noun. These findings violate not only the min rule but also other simple rules for relating typicality in a conjunction to typicalities in the constituents. As an alternative to seeking such rules, we argue for an approach to conceptual combination that starts with the prototype representations themselves. We illustrate one version of this approach in some detail, and show how it accounts for the major findings of the present experiments.
ProtoPeer: a P2P toolkit bridging the gap between simulation and live deployement

Simulators are a commonly used tool in peer-to-peer systems research. However, they may not be able to capture all the details of a system operating in a live network. Transitioning from the simulation to the actual system implementation is a non-trivial and time-consuming task. We present ProtoPeer, a peer-to-peer systems prototyping toolkit that allows for switching between the event-driven simulation and live network deployment without changing any of the application code. ProtoPeer defines a set of APIs for message passing, message queuing, timer operations as well as overlay routing and managing the overlay neighbors. Users can plug in their own custom implementations of most of the parts of ProtoPeer including custom network models for simulation and custom message passing over different network stacks. ProtoPeer is not only a framework for building systems but also for evaluating them. It has a unified system-wide infrastructure for event injection, measurement logging, measurement aggregation and managing evaluation scenarios. The simulator scales to tens of thousands of peers and gives accurate predictions closely matching the live network measurements.
Oxidized LDL , a critical factor in atherogenesis B

There is a great deal of experimental, epidemiological, and clinical evidence suggesting that disorders of lipid metabolism play an important role in the pathogenesis of atherosclerosis. To date, there have been many studies investigating the mechanisms by which high levels of LDL-cholesterol affect biology of vessels and cause atherosclerotic lesion formation [1,2]. It has become abundantly clear over the last decade that the oxidatively modified form of LDL (ox-LDL) is more important than native LDL in atherogenesis. The study in this issue of Cardiovascular Research by Zhu et al. [3] demonstrates that ox-LDL downregulates ATPbinding cassette transporter-1 (ABCA1) in endothelial cells in a dose-dependent manner by inhibiting liver X receptor (LXR) activation. Ox-LDL also attenuates LXR activation by blocking LXR ligand binding and interfering with the generation of 27-hydroxycholesterol, an LXR endogenous ligand. Further, ox-LDL inhibits exogenous cholesterol and oxysterol-induced endothelial ABCA1 induction. Such activity of ox-LDL may contribute to endothelial dysfunction since ABCA1 mediates the active efflux of cholesterol and phospholipids, playing an important role in cholesterol homeostasis and thereby atherogenesis. 3
Lost Letters: Using the Lost-letter Technique to Teach Social Research Methods

Over 50 years ago, Stanley Milgram and colleagues published a short article detailing an unobtrusive experimental design they called the lost-letter technique. The technique involves placing stamped, unmailed letters in a community and using the relative rate of return to infer local attitudes toward political issues and social groups. Furthermore, the technique is simple and inexpensive enough to replicate in an introductory-level social science course as a means to familiarize students with social research methodology. This activity utilizes active learning with student-centered pedagogy, and this paper details the procedure, best practices, and student feedback. Students enjoy having a personal stake in the project and find they better understand social research through this active learning project. Instructors are encouraged to consider adopting the technique in their courses.
A Numerical study of the flow with heat Transfer of a Pseudoplastic fluid Between Parallel Plates

One dimensional flow with heat transfer of a pseudoplastic fluid between two infinite horizontal parallel plates is investigated. The thermophysical properties of the fluid are assumed to be constant and numerical solution using the finite element method, along with the corresponding exact solution for the fluid velocity and the fluid temperature is obtained. The effect of variation of the governing parameters is studied using figures and tables. It is found that the numerical solution agrees well with the corresponding exact solution and that the fluid velocity, together with the fluid temperature, increases with increasing values of the governing parameters.
Cache Analysis of Non-uniform Distribution Sorting Algorithms

We analyse the average-case cache performance of distribution sorting algorithms in the case when keys are independently but not necessarily uniformly distributed. The analysis is for both `in-place' and `out-of-place' distribution sorting algorithms and is more accurate than the analysis presented in \cite{RRESA00}. In particular, this new analysis yields tighter upper and lower bounds when the keys are drawn from a uniform distribution. We use this analysis to tune the performance of the integer sorting algorithm MSB radix sort when it is used to sort independent uniform floating-point numbers (floats). Our tuned MSB radix sort algorithm comfortably outperforms a cache-tuned implementations of bucketsort \cite{RR99} and Quicksort when sorting uniform floats from $[0, 1)$.
Association between hyperpolarization-activated channel in interstitial cells of Cajal and gastrointestinal dysmotility induced by malignant ascites

Advanced malignant ascites is accompanied by gastrointestinal dysmotility, and patients often feel abdominal pain, abdominal distention, nausea and constipation. Gastrointestinal dysmotility is not only painful for the patients, but it reduces the absorption of nutrients and affects the physical recovery of patients with malignant ascites. It is reported that changes in interstitial cells of Cajal (ICCs) are responsible for the gastrointestinal dysmotility induced by malignant ascites, but the mechanism is not completely understood. The present study observed a significantly decreased expression of ion channels, including hyperpolarization-activated cyclic nucleotide-gated potassium channel 2 (HCN2) and cyclic adenosine monophosphate, in the condition of malignant ascites. Using electrophysiology, it was identified that malignant ascites led to lower amplitude and slower frequency signals in cells of the small intestine. In addition, when ICCs were cultured with malignant ascites in vitro, the expression of HCN2 of ICCs was significantly reduced, and the data of flow cytometry revealed that the Ca2+ concentration of ICCs was also decreased. The results of electron microscopy analysis demonstrated the nuclei of ICCs were pyknotic, and the processes of ICCs were reduced in malignant ascites. The present study suggests the small intestinal dysmotility caused by malignant ascites may be associated with changes in HCN2 of ICCs, which offers a potential therapeutic target for gastrointestinal dysmotility in advanced malignant ascites.
Elevated Transcription of the Gene QSOX1 Encoding Quiescin Q6 Sulfhydryl Oxidase 1 in Breast Cancer

The q arm of chromosome 1 is frequently amplified at the gene level in breast cancer. Since the significance of this is unclear we investigated whether 1q genes are overexpressed in this disease. The cDNA levels of 1q-located genes were analysed in a search for overexpressed genes. 26 genes mapping to the 1q arm show highly significant (P≤0.01) overexpression of transcripts in breast cancer compared to normal breast tissue. Amongst those showing the highest levels of overexpression in both expressed sequence tag (EST) and serial analysis of gene expression (SAGE) databases was enzyme quiescin Q6 sulfhydryl oxidase 1 (QSOX1). We investigated QSOX1 cDNA derived from T47D breast carcinoma cells by RT-PCR and 3′-RACE PCR and identified a novel extended form of QSOX1 transcript, containing a long 3′UTR, nearly double the size of the previously reported QSOX1 cDNA, and confirmed its 3′ end nucleotide sequence using RACE-PCR. We also used quantitative real-time PCR to analyse a panel of cDNAs derived from 50 clinically-graded normal and malignant breast tissue samples for the expression of QSOX1 mRNAs. QSOX1 transcription was elevated in an increasing proportion in the grade 2 and grade 3 tumours (graded according to the Nottingham prognostic index), with 10 of the 15 grade 3 tumours (67%) examined exceeding the normal range. There was a significant correlation between relative transcript level and clinical grade (P≤0.01) for all qPCR primer sets tested. QSOX1 mRNA levels, based on SAGE expression data, did not correlate with either Estrogen Receptor (ER) or Epidermal Growth Factor Receptor 2 (ErbB-2 or HER2/neu) expression. Our data indicate that QSOX1 is a potential new prognostic marker which may prove of use in the staging of breast tumours and the stratification of breast cancer patients.
Seeing objects as face modulates visual search performance

Some products are explicitly or implicitly designed so that objects can be seen as a face; this will possibly support a fluent human-environment communication. The present study investigated the effects of seeing objects as face on human's visual search performance by means of psychological experiments. The participants were asked to search a target among distractors on a computer display as quickly as possible. The target and distractors differed in the vertical direction. The participants were randomly assigned to a face task or a triangle task. In the face task, the visual stimulus was either a cartoon face or three dots arranged in triangle that could be seen as a face, and the participants were instructed to search a upright or inverted face among distractors. In the triangle task, the visual stimulus was either the three dots same as the face task or a line-drawing triangle, and the participants were instructed to search a triangle. In both tasks, two types of stimuli were randomly presented during the trial sequence. We found that visual search for the three-dot target was slower in the face task than in the triangle task. However, when the target stimulus was informed immediately before each trial, the results were reversed; visual search for the three-dot target in the face task was faster than in the triangle task. These results suggest that, even if the target stimulus par se is identical, seeing the target as face modulates visual search performance, and the effects interact with expectation or preparation of the subsequent target.
Spatial auditory BCI paradigm based on real and virtual sound image generation

This paper presents a novel concept of spatial auditory brain-computer interface utilizing real and virtual sound images. We report results obtained from psychophysical and EEG experiments with nine subjects utilizing a novel method of spatial real or virtual sound images as spatial auditory brain computer interface (BCI) cues. Real spatial sound sources result in better behavioral and BCI response classification accuracies, yet a direct comparison of partial results in a mixed experiment confirms the usability of the virtual sound images for the spatial auditory BCI. Additionally, we compare stepwise linear discriminant analysis (SWLDA) and support vector machine (SVM) classifiers in a single sequence BCI experiment. The interesting point of the mixed usage of real and virtual spatial sound images in a single experiment is that both stimuli types generate distinct event related potential (ERP) response patterns allowing for their separate classification. This discovery is the strongest point of the reported research and it brings the possibility to create new spatial auditory BCI paradigms.
GPGPU Benchmark Suites: How Well Do They Sample the Performance Spectrum?

Recently, GPGPUs have positioned themselves in the mainstream processor arena with their potential to perform a massive number of jobs in parallel. At the same time, many GPGPU benchmark suites have been proposed to evaluate the performance of GPGPUs. Both academia and industry have been introducing new sets of benchmarks each year while some already published benchmarks have been updated periodically. However, some benchmark suites contain benchmarks that are duplicates of each other or use the same underlying algorithm. This results in an excess of workloads in the same performance spectrum. In this paper, we provide a methodology to obtain a set of new GPGPU benchmarks that are located in the unexplored region of the performance spectrum. Our proposal uses statistical methods to understand the performance spectrum coverage and uniqueness of existing benchmark suites. Later we show techniques to identify areas that are not explored by existing benchmarks by visually showing the performance spectrum coverage. Finding unique key metrics for future benchmarks to broaden its performance spectrum coverage is also explored using hierarchical clustering and ranking by Hotel ling's T2 method. Finally, key metrics are categorized into GPGPU performance related components to show how future benchmarks can stress each of the categorized metrics to distinguish themselves in the performance spectrum. Our methodology can serve as a performance spectrum oriented guidebook for designing future GPGPU benchmarks.
Cardiac Alpha-Myosin (MYH6) Is the Predominant Sarcomeric Disease Gene for Familial Atrial Septal Defects

Secundum-type atrial septal defects (ASDII) account for approximately 10% of all congenital heart defects (CHD) and are associated with a familial risk. Mutations in transcription factors represent a genetic source for ASDII. Yet, little is known about the role of mutations in sarcomeric genes in ASDII etiology. To assess the role of sarcomeric genes in patients with inherited ASDII, we analyzed 13 sarcomeric genes (MYH7, MYBPC3, TNNT2, TCAP, TNNI3, MYH6, TPM1, MYL2, CSRP3, ACTC1, MYL3, TNNC1, and TTN kinase region) in 31 patients with familial ASDII using array-based resequencing. Genotyping of family relatives and control subjects as well as structural and homology analyses were used to evaluate the pathogenic impact of novel non-synonymous gene variants. Three novel missense mutations were found in the MYH6 gene encoding alpha-myosin heavy chain (R17H, C539R, and K543R). These mutations co-segregated with CHD in the families and were absent in 370 control alleles. Interestingly, all three MYH6 mutations are located in a highly conserved region of the alpha-myosin motor domain, which is involved in myosin-actin interaction. In addition, the cardiomyopathy related MYH6-A1004S and the MYBPC3-A833T mutations were also found in one and two unrelated subjects with ASDII, respectively. No mutations were found in the 11 other sarcomeric genes analyzed. The study indicates that sarcomeric gene mutations may represent a so far underestimated genetic source for familial recurrence of ASDII. In particular, perturbations in the MYH6 head domain seem to play a major role in the genetic origin of familial ASDII.
Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 1321 Working conditions and musculoskeletal disorders in flight baggage handling

Bergsten, E. L. 2017. Working conditions and musculoskeletal disorders in flight baggage handling. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 1321. 59 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9868-9. Introduction: Baggage handling is considered to be a heavy manual handling job including biomechanical exposures suspected of increasing the risk for musculoskeletal disorders. Aims: To document low back pain (LBP), shoulder pain (SP), and physical and psychosocial factors in baggage handlers, and to evaluate the implementation of an ergonomic intervention aiming to increase the use of loading assist devices. Methods: A questionnaire was utilized to characterize pain and psychosocial work conditions in 525 baggage handlers. The postures of 55 baggage handlers during 114 shifts were measured using inclinometry, half shift videorecordings were made for subsequent task analysis, and the number of aircraft handled was registered. Associations for psychosocial and biomechanical exposures with pain were assessed using regression analyses. An ergonomic intervention was implemented and evaluated using questionnaires and repeated interviews. Feasibility, intermediate outcomes, barriers and facilitators were assessed. Results: The prevalence rates of reported LBP and SP were 70% and 60%, respectively. Pain interfering with work (LBP 30% and SP 18%) and high pain intensity (LBP 34% and SP 28%) were associated with poor psychosocial working conditions. Extreme postures with arms elevated >60° occurred for 6.4% of the total time, and in trunk flexion >60° for 2.1% total time. In contrast, 71% of the total time was spent in a neutral trunk posture. The 90 percentile trunk forward flexion was 34.1°. Daily shoulder pain increased in approximately one-third of all shifts and was positively associated with extreme work posture and the number of aircraft handled; this association was modified by influence and support. The intervention was delivered as planned, and dose received and satisfaction were rated as high. Motivated trainees facilitated implementation while lack of manager support, opportunities to observe and practice behaviors, follow-up activities, staff reduction, and job insecurity were barriers. Conclusion: The high prevalence rates of LBP and SP in baggage handlers were associated with psychosocial exposures, and daily shoulder pain was associated with higher biomechanical exposure. Barriers to implementation can be minimized by recruiting motivated trainees, securing strong organizational support, and carrying out follow-up activities.
Convergence analysis of an incremental approach to online inverse reinforcement learning

Interest in inverse reinforcement learning (IRL) has recently increased, that is, interest in the problem of recovering the reward function underlying a Markov decision process (MDP) given the dynamics of the system and the behavior of an expert. This paper deals with an incremental approach to online IRL. First, the convergence property of the incremental method for the IRL problem was investigated, and the bounds of both the mistake number during the learning process and regret were provided by using a detailed proof. Then an online algorithm based on incremental error correcting was derived to deal with the IRL problem. The key idea is to add an increment to the current reward estimate each time an action mismatch occurs. This leads to an estimate that approaches a target optimal value. The proposed method was tested in a driving simulation experiment and found to be able to efficiently recover an adequate reward function.
A VOLUME-LIMITED SAMPLE OF 63 M7–M9.5 DWARFS. I. SPACE MOTION, KINEMATIC AGE, AND LITHIUM

In a volume-limited sample of 63 ultracool dwarfs of spectral type M7–M9.5, we have obtained high-resolution spectroscopy with UVES at the Very Large Telescope and HIRES at Keck Observatory. In this first paper we introduce our volume-complete sample from DENIS and 2MASS targets, and we derive radial velocities and space motion. Kinematics of our sample are consistent with the stars being predominantly members of the young disk. The kinematic age of the sample is 3.1 Gyr. We find that six of our targets show strong Li lines implying that they are brown dwarfs younger than several hundred million years. Five of the young brown dwarfs were unrecognized before. Comparing the fraction of Li detections to later spectral types, we see a hint of an unexpected local maximum of this fraction at spectral type M9. It is not yet clear whether this maximum is due to insufficient statistics, or to a combination of physical effects including spectral appearance of young brown dwarfs, Li line formation, and the star formation rate at low masses.
