Building Rapport with Extraverted and Introverted Agents

Psychology research reports that people tend to seek companionship with those who have a similar level of extraversion, and markers in dialogue show the speaker’s extraversion. Work in human-computer interaction seeks to understand creating and maintaining rapport between humans and ECAs. This study examines if humans will report greater rapport when interacting with an agent with an extraversion/introversion profile similar to their own. ECAs representing an extrovert and an introvert were created by manipulating three dialogue features. Using an informal, task-oriented setting, participants interacted with one of the agents in an immersive environment. Results suggest that subjects did not report the greatest rapport when interacting with the agent most similar to their level of extraversion. Introduction People often seek companionship with those who have a personality similar to their own [11]. There is evidence that personality types are borne out in dialogue choices [1]. Humans are uniquely physically capable of speech, and tend to find spoken communication as the most efficient and comfortable way to interact, including with technology [2]. They respond to computer personalities in the same way as they would to human personalities [10]. Recent research has sought to understand the nature of creating and maintaining rapport—a sense of emotional connection—when communicating with embodied conversational agents (ECAs) [2, 8, 14]. Successful ECAs could serve in a number of useful applications, from education to care giving. As human relationships are fundamentally social and emotional, these qualities must be incorporated into ECAs if human-agent relationships are to feel natural to users. Research has been focused on the development and maintenance of rapport felt by humans when interacting with an ECA [11] and in developing ECA personalities [3]. However, questions remain as to which agent personality is the best match for developing rapport in human-ECA interactions. In this study, two agents representing an extravert and an introvert were created by manipulating three dialogue features. Using a task-oriented but informal set-
Comparison of advanced iterative reconstruction methods for SPECT/CT.

AIM
Corrective image reconstruction methods which produce reconstructed images with improved spatial resolution and decreased noise level became recently commercially available. In this work, we tested the performance of three new software packages with reconstruction schemes recommended by the manufacturers using physical phantoms simulating realistic clinical settings.


METHODS
A specially designed resolution phantom containing three (99m)Tc lines sources and the NEMA NU-2 image quality phantom were acquired on three different SPECT/CT systems (General Electrics Infinia, Philips BrightView and Siemens Symbia T6). Measurement of both phantoms was done with the trunk filled with a (99m)Tc-water solution. The projection data were reconstructed using the GE's Evolution for Bone(®), Philips Astonish(®) and Siemens Flash3D(®) software. The reconstruction parameters employed (number of iterations and subsets, the choice of post-filtering) followed theses recommendations of each vendor. These results were compared with reference reconstructions using the ordered subset expectation maximization (OSEM) reconstruction scheme.


RESULTS
The best results (smallest value for resolution, highest percent contrast values) for all three packages were found for the scatter corrected data without applying any post-filtering. The advanced reconstruction methods improve the full width at half maximum (FWHM) of the line sources from 11.4 to 9.5mm (GE), from 9.1 to 6.4mm (Philips), and from 12.1 to 8.9 mm (Siemens) if no additional post filter was applied. The total image quality control index measured for a concentration ratio of 8:1 improves for GE from 147 to 189, from 179. to 325 for Philips and from 217 to 320 for Siemens using the reference method for comparison. The same trends can be observed for the 4:1 concentration ratio. The use of a post-filter reduces the background variability approximately by a factor of two, but deteriorates significantly the spatial resolution.


CONCLUSIONS
Using advanced reconstruction algorithms the largest improvement in image resolution and contrast is found for the scatter corrected slices without applying post-filtering. The user has to choose whether noise reduction by post-filtering or improved image resolution fits better a particular imaging procedure.
Beam-steerable Planar Array Antennas Using Varactor Diodes for 60-GHz-band Applications

In this paper we present low-cost and compact beam-steerable planar microstrip antennas for 60-GHz applications. The substrates have three dielectric layers, a ground plane between the bottom and middle dielectric layers, and radiation elements of microstrip antennas on the top dielectric layer. The radiation elements are fed in series by a circuit based on the microstrip-to-slotline transition and the slotline-to-microstrip transition. A feed network of the symmetric structure is developed by fully using the in-phase and anti-phase power dividing techniques. In the feed network, phase shifters using varactor diodes are inserted to steer the beam direction. We fabricated the antennas, measured the antenna characteristics, and evaluated the performance in beam steering. The antenna gain is about 16 dBi, and the bandwidth is more than 4 GHz for a 24-element antenna. Experimental results show that the proposed beam-steerable antenna has the ability of about 7-degree beam steering at the frequency of 60 GHz. Since the phase shifters of this antenna consist of varactor diodes, unlike active phased arrays, the beam-steerable antenna can be fabricated at low cost.
Measurement of atomic elastic constants by pulsed neutron powder diffraction

A technique for determining the atomic elastic constants from measurements of the Debye-Waller factors has been developed. The Debye-Waller factors are obtained by Rietveld refinement of time-of- flight neutron diffraction data and interpretation in terms of an atomic Debye-Waller temperature. The method is applicable to powders and to materials that must be encapsulated for safety or environmental reasons. Illustrations of the technique with applications to actinide metals, to metallic hydrides and to high- temperature superconductors are presented. (JDB)

Periprocedural bleeding complications of brain AVM embolization with Onyx.

UNLABELLED
The advent of Onyx has provided a new method for neurointerventional therapists to treat brain AVMs. Although some retrospective studies have reported complications for AVM embolization with Onyx, periprocedural bleeding complications with Onyx embolization have not yet been described in detail. The aim of this retrospective study was to analyze the factors of Onyx-related bleeding complications and to find a way to avoid and manage these complications.From January 2003, patients with AVMs recruited in our institution started to be treated by Onyx embolization. From January 2007 to July 2009, 143 consecutive interventions were performed in 126 patients using flow-independent microcatheters and Onyx as embolic agents. Seven patients encountered bleeding complications (5.4% per patients and 4.7% per procedures) during or after the endovascular procedures. Among them, five bleeding episodes occurred during procedures, the other two after procedures. Details of the seven patients' clinical presentations, imaging presentations, speculative reasons and management of these complications were recorded. Follow-up data, including postoperative course, clinical symptoms and duration of follow-up were documented. The five active bleedings discovered in procedures were managed in time, and the patients recovered without any new neurological symptoms compared with preoperation. However, of the two bleeding episodes that occurred after interventional procedures, one was detected half an hour later: the patient was remained comatose two months later after resection of right occipital hematoma; the other who encountered intraventricular and midbrain hemorrhage was treated conservatively and suffered Parinaud syndrome and hemianesthesia.


CONCLUSION
Periprocedural bleeding of AVMs embolization is considered a severe and devastating complication. The clinical course and prognosis of bleeding mostly depends on prompt detection and management. Interventional embolization is an effective method to manage bleeding during procedures, and the detection of risk factors and imaging signs of bleeding is extremely important.

Правовая культура и образование

The article discusses various approaches to understanding the legal culture, particularly among young people in Russia's legal space. Socio-philosophical interpretation of the legal culture reveals, on the one hand, society's need for it, but on the other the ambiguity of its assessment and significance.
Measuring shortness of breath in heart failure (SOB-HF): development and validation of a new dyspnoea assessment tool.

AIM
To validate a previously developed instrument for measurement of breathlessness in patients with acute heart failure (HF).


METHODS AND RESULTS
We tested descriptors of breathlessness among 190 patients seeking care at the emergency department (ED) for acute shortness of breath. Out of 115 patients with confirmed HF, 107 (94%) had dyspnoea as their main symptom. There were no significant differences between those patients with HF and those who were not diagnosed as heart failure (NHF) (n = 75) in the descriptors of breathlessness, although patients with HF scored significantly (P = 0.03) higher on a visual analogue scale (VAS). In addition, they had significantly (P = 0.03) higher breathing frequency than NHF patients and they were significantly (P < 0.001) more likely to be treated with >40 mg furosemide.


CONCLUSION
Assessment of acute dyspnoea using a VAS is useful in distinguishing HF from NHF, and may be a more valid approach as compared with using descriptors of intensity of breathlessness in the acute setting.
Study protocol for patient response to spinal manipulation – a prospective observational clinical trial on physiological and patient-centered outcomes in patients with chronic low back pain

BACKGROUND
Low back pain (LBP) is a major health issue due to its high prevalence rate and socioeconomic cost. While spinal manipulation (SM) is recommended for LBP treatment by recently published clinical guidelines, the underlying therapeutic mechanisms remain unclear. Spinal stiffness is routinely examined and used in clinical decisions for SM delivery. It has also been explored as a predictor for clinical improvement. Flexion-relaxation phenomenon has been demonstrated to distinguish between LBP and healthy populations. The primary objective of the current study is to collect preliminary estimates of variability and effect size for the associations of these two physiological measures with patient-centered outcomes in chronic LBP patients. Additionally biomechanical characteristics of SM delivery are collected with the intention to explore the potential dose-response relationship between SM and LBP improvement.


METHODS/DESIGN
This is a prospective, observational study applying side-lying, high velocity, low amplitude SM as treatment for patients with LBP over a course of 6 weeks. Approximately 80 participants will be enrolled if they present with chronic LBP of 1, 2 or 3 in Quebec Task Force Classification for spinal disorders, a Roland-Morris Disability Questionnaire (RMDQ) score ≥ 6, and persistent LBP ≥ 2 with a maximum ≥ 4 using numerical rating scale. Patient-centered outcomes include LBP using visual analog scale, RMDQ, and PROMIS-29. Lumbar spine stiffness is assessed using palpation, a hand-held instrumented device, and an automated device. Flexion-relaxation is assessed using surface electromyography at the third level of the lumbar spine. Biomechanical characteristics of SM are assessed using a self-reported, itemized description system, as well as advanced kinetic measures that will be applied to estimate forces and moments at the lumbar segment level targeted by SM.


DISCUSSION
Beside alterations in material properties of the passive components of the spine, increased neuromuscular activity may also contribute to a stiffened spine. Examining changes in both spinal stiffness and flexion-relaxation along the course of the treatment provides an opportunity to understand if the therapeutic effect of SM is associated with its action on active and/or passive components of the spine.

Geological disposal of nuclear waste: II. From laboratory data to the safety analysis - Addressing societal concerns

After more than 30 years of international research and development, there is a broad technical consensus that geologic disposal of highly-radioactive waste will provide for the safety of humankind and the environment, now, and far into the future. Safety analyses have demonstrated that the risk, as measured by exposure to radiation, will be of little consequence. Still, there is not yet an operating geologic repository for highly-radioactive waste, and there remains substantial public concern about the long-term safety of geologic disposal. In these two linked papers, we argue for a stronger connection between the scientific data (paper I, Grambow et al., 2014) and the safety analysis, particularly in the context of societal expectations (paper II). In this paper (II), we assess the meaning of the technical results and derived models (paper I) for the determination of the long-term safety of a repository. We consider issues of model validity and their credibility in the context of a much broader historical, epistemological and societal context. Safety analysis is treated in its social and temporal dimensions. This perspective provides new insights into the societal dimension of scenarios and risk analysis. Surprisingly, there is certainly no direct link between increased scientific understanding and a public position for or against different strategies of nuclear waste disposal. This is not due to the public being poorly informed, but rather due to cultural cognition of expertise and historical and cultural perception of hazards to regions selected to host a geologic repository. The societal and cultural dimension does not diminish the role of science, as scientific results become even more important in distinguishing between the conflicting views of the risk of geologic disposal of nuclear waste. 2014 Elsevier Ltd.

Radiotherapy with concurrent carbogen and nicotinamide in bladder carcinoma.

PURPOSE
Phase II clinical studies suggest that hypoxic modification with carbogen and nicotinamide (CON) may increase the efficacy of radiotherapy (RT).


PATIENTS AND METHODS
Three hundred thirty-three patients with locally advanced bladder carcinoma were randomly assigned to RT alone versus RT with CON. A schedule of either 55 Gy in 20 fractions in 4 weeks or 64 Gy in 32 fractions in 6.5 weeks was used. The primary end point was cystoscopic control at 6 months (CC(6m)) and secondary end points were overall survival (OS), local relapse-free survival (RFS), urinary and rectal morbidity.


RESULTS
CC(6m) was 81% for RT + CON and 76% for RT alone (P = .3); however, just more than half of patients underwent cystoscopy at that time. Three-year estimates of OS were 59% and 46% (P = .04) and 3-year estimates of RFS were 54% and 43% (P = .06) for RT + CON versus RT alone. Risk of death was 14% lower with RT + CON (P = .04). In multivariate comparison, RT + CON significantly reduced the risk of relapse (P = .05) and death (P = .03). There was no evidence that differences in late urinary or GI morbidity between treatment groups or between fractionation schedules were significant.


CONCLUSION
RT + CON produced a small nonsignificant improvement in CC(6m). Differences in OS, risk of death, and local relapse were significantly in favor of RT + CON. Late morbidity was similar in both trial arms. Results indicate a benefit of adding CON to radical RT.
Extending the Use of Games in Health Care

Digital games have the ability to engage both children and adults alike. We are exploring the use of games for children with long term treatment regimes, where motivation for compliance is a key factor in the success of the treatment. In this paper, we describe the game framework we are building for this purpose. This framework is meant to support the long term use of a gaming world for children with three main goals: (a) provide easy and continual gaming access on a range of computing appliances including small screen devices; (b) offer games that can be personalized and are adaptable based on the child’s interests or specific illness; and (c) maintain novelty and interest in the treatment over time. This framework not only provides a benefit to the children involved, but also provides user data to the coaches, clinicians, and health researchers involved in the child’s treatment regime.
Effect of coumarins started before coronary angioplasty on acute complications and long-term follow-up: a randomized trial.

BACKGROUND
Coronary angioplasty frequently creates a thrombogenic surface, with subsequent mural thrombosis that may lead to acute complications and possibly stimulates the development of restenosis. Whether coumarins can prevent these complications is unclear. The objective of this open, randomized trial was to assess the clinical effect of coumarins started before coronary angioplasty and continued for 6 months.


METHODS AND RESULTS
Before coronary angioplasty, 530 patients were randomly assigned to aspirin plus coumarins and 528 patients to aspirin alone. At the start of the angioplasty, the mean international normalized ratio was 2.7+/-1.1; during follow-up, it was 3.0+/-1.1. At 30 days, the composite end point of death, myocardial infarction, target-lesion revascularization, and stroke was observed in 18 patients (3.4%) treated with aspirin plus coumarin compared with 34 patients (6.4%) treated with aspirin alone (relative risk, 0.53; 95% CI, 0.30 to 0.92). At 1 year, these figures were 14.3% and 20.3%, respectively (relative risk, 0.71; 95% CI, 0.54 to 0.93). The incidence of major bleeding and false aneurysm during hospitalization was 3.2% and 1.0%, respectively (relative risk, 3.39; 95% CI, 1.26 to 9.11). The benefit of coumarins was observed in both stented and nonstented patients.


CONCLUSIONS
Coumarins in addition to aspirin started before PTCA and continued for 6 months was more effective than aspirin alone in the prevention of acute and late complications after coronary angioplasty. This benefit was accompanied by a small but significant increase in bleeding complications.
Safety, liveness and fairness in temporal logic

In this paper we present syntactic characterization of temporal formulas that express various properties of interest in the verification of concurrent programs. Such a characterization helps us in choosing the right techniques for proving correctness with respect to these properties. The properties that we consider include safety properties, liveness properties and fairness properties. We also present algorithms for checking if a given temporal formula expresses any of these properties.
FAST: A Framework to Accelerate Super-Resolution Processing on Compressed Videos

State-of-the-art super-resolution (SR) algorithms require significant computational resources to achieve real-time throughput (e.g., 60Mpixels/s for HD video). This paper introduces FAST (Free Adaptive Super-resolution via Transfer), a framework to accelerate any SR algorithm applied to compressed videos. FAST exploits the temporal correlation between adjacent frames such that SR is only applied to a subset of frames; SR pixels are then transferred to the other frames. The transferring process has negligible computation cost as it uses information already embedded in the compressed video (e.g., motion vectors and residual). Adaptive processing is used to retain accuracy when the temporal correlation is not present (e.g., occlusions). FAST accelerates state-of-the-art SR algorithms by up to 15× with a visual quality loss of 0.2dB. FAST is an important step towards real-time SR algorithms for ultra- HD displays and energy constrained devices (e.g., phones and tablets).
Comparison of Montreal Cognitive Assessment and Mini-Mental State Examination in Evaluating Cognitive Domain Deficit Following Aneurysmal Subarachnoid Haemorrhage

OBJECTIVE
Cognitive deficits are common after aneurysmal subarachnoid haemorrhage (aSAH), and clinical evaluation is important for their management. Our hypothesis was that the Montreal Cognitive Assessment (MoCa) is superior to the Mini-Mental State Examination (MMSE) in screening for cognitive domain deficit in aSAH patients.


METHODS
We carried out a prospective observational and diagnostic accuracy study on Hong Kong aSAH patients aged 21 to 75 years who had been admitted within 96 hours of ictus. The domain-specific neuropsychological assessment battery, the MoCA and MMSE were administered 2-4 weeks and 1 year after ictus. A cognitive domain deficit was defined as a cognitive domain z score <-1.65 (below the fifth percentile). Cognitive impairment was defined as two or more cognitive domain deficits. The study is registered at ClinicalTrials.gov of the US National Institutes of Health (NCT01038193).


RESULTS
Both the MoCA and the MMSE were successful in differentiating between patients with and without cognitive domain deficits and cognitive impairment at both assessment periods. At 1 year post-ictus, the MoCA produced higher area under the curve scores for cognitive impairment than the MMSE (MoCA, 0.92; 95% CI, 0.83 to 0.97 versus MMSE, 0.77; 95% CI, 0.66 to 0.83, p = 0.009).


INTERPRETATION
Cognitive domain deficits and cognitive impairment in patients with aSAH can be screened with the MoCA in both the subacute and chronic phases.
