Perceptual modeling for stereoscopic 3D

Virtual and Augmented Reality applications typically rely on both stereoscopic presentation and involve intensive object and observer motion. A combination of high dynamic range and stereoscopic capabilities become popular for consumer displays, and is a desirable functionality of head mounted displays to come. The thesis is focused on complex interactions between all these visual cues on digital displays. The first part investigates challenges of the stereoscopic 3D and motion combination. We consider an interaction between the continuous motion presented as discrete frames. Then, we discuss a disparity processing for accurate reproduction of objects moving in the depth direction. Finally, we investigate the depth perception as a function of motion parallax and eye fixation changes by means of saccadic motion. The second part focuses on the role of high dynamic range imaging for stereoscopic displays. We go beyond the current display capabilities by considering the full perceivable luminance range and we simulate the real world experience in such adaptation conditions. In particular, we address the problems of disparity retargeting across such wide luminance ranges and reflective/refractive surface rendering. The core of our research methodology is perceptual modeling supported by our own experimental studies to overcome limitations of current display technologies and improve the viewer experience by enhancing perceived depth, reducing visual artifacts or improving viewing comfort. Anwendungen von virtueller und erweiterter Realitat verwenden in der Regel eine stereoskopische Darstellung und schliesen intensive Objekt- und Betrachterbewegung ein. Die Integration von hohen Dynamikumfangen stellt eine weitere erstrebenswerte Funktionalitat dar. Diese Arbeit beschaftigt sich mit den komplexen Wechselwirkungen zwischen all diesen visuellen Wahrnehmungselementen. Wir beschreiben die Enschrankungen aktueller Bildschirmtechnologien und uberwinden sie, indem wir Wahrnehmungsmodelle zusammen mit unseren eigenen Studien verwenden, um den Betrachterkomfort zu steigern, die wahrgenommen Tiefe zu verstarken und visuelle Artefakte zu reduzieren. Der erste Teil untersucht die Herausforderungen die entstehen, wenn stereoskopisches 3D mit Bewegung kombiniert wird. Wir betrachten Wechselwirkungen zwischen kontinuierlicher Bewegung, die in Form diskreter Einzelbilder dargestellt wird. Weiterhin untersuchen wir die Tiefenwahrnehmung sowohl von Objekten, die sich in die Tiefenrichtung bewegen, als auch bei Bewegungsparallaxe und Fixationsveranderungen des Auges mittels sakkadischer Bewegung. Der zweite Teil beschaftigt sich mit der Rolle von Bildern mit hohem Dynamikumfang. Indem wir den kompletten wahrnehmbaren Luminanzumfang betrachten, uberschreiten wir die Moglichkeiten aktueller Bildschirme und analysieren die Anpassung von Disparitaten und das Rendern von reflektierenden Oberflachen in solch unterschiedlichen Bedingungen.
Pseudohypopyon Following Intravitreal Triamcinolone Acetonide Injection

Objective: To report a case of a pseudohypopyon that developed after intravitreal injection of triamcinolone acetonide for choroidal neovascularization from age-related macular degeneration. Methods: Observational case report. Results: A 62-year-old woman received an intravitreal injection of triamcinolone acetonide for the treatment of a choroidal neovascular membrane that developed as a result of age-related macular degeneration. A layer of yellowish deposits was observed in the anterior chamber 1 day after the injection. The patient denied any pain or reduced vision, and there was no redness noted on examination. The deposits cleared spontaneously on the fourth postoperative day. Conclusions: Pseudohypopyon may develop after intravitreal injection of triamcinolone acetonide. Distinguishing this from a true hypopyon is important because the treatment and prognosis are very different for the two conditions.
Identifying the Most Critical Factors to Business Intelligence Implementation Success in the Public Sector Organizations

The BI is a new trend in public sector organizations that requires investigating the critical success factors (CSFs) which would provide a sound guidelines for determining the criteria to be considered during BI implementation. However, there is no sufficient empirical evidences that provide better understanding of the CSFs for the BI implementation in public sector organizations. This paper aims to identify the CSFs for BI system in the context of public sector organizations. This study adopts a mixed method approach using survey research method and qualitative interview using Jordanian public sector organization case. The findings of this research revealed that top management support, clear vision and strategic planning, team skills, user participation, organizational structure, user access and development technology are the most critical factors to BI implementation success in the public sector organizations. The findings of this study could assist the practitioners in the public sector organizations in planning, managing and implementing their BI projects properly by focusing on those CSFs of BI systems that provide them a better understanding to address issues and concerns related to BI implementation.
Mitigation Of Replay Attack In Wireless Sensor Network

— Wireless Sensor Networks are deployed in many applications. They are tasked to facilitate data over a wide range of geographical locations that are inaccessible to human capabilities. In this scenario WSNs are designed to perform in remote locations for a long period of time. WSNs operate themselves to save their batteries and constantly enter into their sleep mode by a pre-defined security protocol. The major threat in this kind of deployment is the attacking mechanisms that focus to initiate the malfunctioning of the sensor nodes. Many attacks are classified according to their nature of disruption, some being general noise attacks to penetrating attacks that intrude to whole system with unauthenticated signals. Security mechanism significantly eradicates all the false signals but the power consumption for analysing the incoming data rises exponentially due to the fact that nodes are denied to enter into their sleep mode. This attack is a segment of denial-of-sleep attack which includes replay attack. Replay attacks are the intelligent attacks that replays overhead frames as they are or with minor alteration. This paper presents a novel approach to mitigate the impact of aforementioned attacks which incorporates Distributed Energy Efficient Clustering (DEEC) with Elliptic Curve Cryptography (ECC) and Bloom Filter.
Exploiting the short - term and long - term channel properties in space and time: Eigenbeamforming concepts for the BS in WCDMA

The deployment of adaptive antennas at base stations considerably increases the spectral efficiency of wireless communication systems. To reduce the computational complexity and increase performance of space—time (ST) processing, processing may take place in reduced dimension, i. e. , pre—filtering takes place which is related to linear estimation theory based on second order statistics. To this end, long—term and short—term channel estimates are integrated into specific Tx/Rx systems. In this article, we present a new ST rake structure for uplink reception in WCDMA which operates in reduced dimension. Accordingly, our approach combines short—term and long—term spatial and temporal channel properties using an eigenanalysis. By choosing dominant eigenbeams in time and space, the algorithm enhances interference suppression as well as spatial and temporal receive diversity. In contrast to previously introduced well—known receiver structures, the ST eigenrake inherently adapts to different propagation environments and achieves higher spectral efficiency than other receivers. This is illustrated by Monte—Carlo simulations. Then we extend the proposed concept to the downlink. The downlink eigenbeamformer improves closed—loop downlink diversity compared to other proposals in standardization (3GPP) which only exploit short—term channel properties. Even though the short—term feedback rate remains unchanged, additional antenna elements can be included to increase antenna and diversity gain. We also present a tracking solution to the downlink eigenbeamforming in WCDMA. To this end, we propose a distributed implementation of the eigenspace/—beam tracking at the mobile terminal and base station (BS), respectively. Moreover, the specific nature of the deployed tracking scheme offers an advantageous feedback signalling.
Error Analysis of a Finite Difference Method on Graded Meshes for a Time-Fractional Diffusion Equation

A reaction-diffusion problem with a Caputo time derivative of order $\alpha\in (0,1)$ is considered. The solution of such a problem is shown in general to have a weak singularity near the initial time $t=0$, and sharp pointwise bounds on certain derivatives of this solution are derived. A new analysis of a standard finite difference method for the problem is given, taking into account this initial singularity. This analysis encompasses both uniform meshes and meshes that are graded in time, and includes new stability and consistency bounds. The final convergence result shows clearly how the regularity of the solution and the grading of the mesh affect the order of convergence of the difference scheme, so one can choose an optimal mesh grading. Numerical results are presented that confirm the sharpness of the error analysis.
A measurement of G with a cryogenic torsion pendulum

A measurement of Newton's gravitational constant G has been made with a cryogenic torsion pendulum operating below 4 K in a dynamic mode in which G is determined from the change in torsional period when a field source mass is moved between two orientations. The source mass was a pair of copper rings that produced an extremely uniform gravitational field gradient, whereas the pendulum was a thin fused silica plate, a combination that minimized the measurement's sensitivity to error in pendulum placement. The measurement was made using an as-drawn CuBe torsion fibre, a heat-treated CuBe fibre, and an as-drawn Al5056 fibre. The pendulum operated with a set of different large torsional amplitudes. The three fibres yielded high Q-values: 82 000, 120 000 and 164 000, minimizing experimental bias from fibre anelasticity. G-values found with the three fibres are, respectively: {6.67435(10),6.67408(15),6.67455(13)}×10−11 m3 kg−1 s−2, with corresponding uncertainties 14, 22 and 20 ppm. Relative to the CODATA2010 G-value, these are higher by 77, 37 and 107 ppm, respectively. The unweighted average of the three G-values, with the unweighted average of their uncertainties, is 6.67433(13)×10−11 m3 kg−1 s−2 (19 ppm).
Predictors of Exposure From an Antimarijuana Media Campaign: Outcome Research Assessing Sensation Seeking Targeting

Using data from a large-scale antimarijuana media campaign, this investigation examined the demographic and psychographic variables associated with exposure to public service announcements designed to target high sensation-seeking adolescents. The literature on sensation seeking indicates that adolescents high in this trait are at greater risk for substance abuse. Analyses assessed the predictive utility of various risk and protective factors, normative influences, demographic variables, and marijuana-related attitudes, intentions, and behaviors on campaign message exposure. Results confirm that level of sensation seeking was positively associated with greater message exposure. In addition, viewers reporting greater exposure were younger adolescents who indicated that they had poor family relations, promarijuana attitudes, and friends and family who used marijuana. Implications for designing future antimarijuana messages based on these findings are discussed.
Mouse oocytes suppress cAMP‐induced expression of LH receptor mRNA by granulosa cells in vitro

Mouse oocytes suppress follicle‐stimulating hormone (FSH)–induced luteinizing hormone receptor (LHR) messenger ribonucleic acid (mRNA) expression in cultured granulosa cells. The objective of this study was to assess the mechanism by which oocytes suppress FSH‐induced LHR expression. The effect of cumulus cell–denuded, germinal‐vesicle‐stage oocytes, isolated from antral follicles, on FSH‐induced cyclic adenosine monophosphate (cAMP) production by cultured granulosa cells was determined by radioimmunoassays. In addition, the effect of oocytes on 8Br‐cAMP–induced LHR mRNA steady‐state expression by granulosa cells was assessed by RNase protection assays. Oocytes had no detectable effect on FSH‐induced cAMP production. However, oocytes dramatically suppressed 8Br‐cAMP–induced LHR mRNA steady‐state expression by granulosa cells. It was concluded that the mechanism by which oocytes suppress FSH‐induced steady‐state expression of LHR mRNA is not by inactivating FSH, preventing functional interactions of FSH with its granulosa cell receptors, or by interfering with the signal‐transduction mechanisms required for FSH‐dependent cAMP production. In addition, since oocytes suppressed the 8Br‐cAMP–induced increase in steady‐state expression of mRNA for LHR, oocyte‐derived factors probably suppress expression by acting downstream of FSH‐induced elevation of granulosa cell cAMP.

Role of multiple inelastic transitions in atom transfer with the scanning tunneling microscope.

The high current density obtainable with the scanning tunneling microscope can be used to promote multiple vibrational excitations of an adsorbate via inelastic electron tunneling. Calculations indicate that this effect plays an important role in the transfer of Xe atoms between a sample and tip by the application of current pulses. Directionality of atom transfer and applications to other systems are discussed
Nasal versus oral intubation for mechanical ventilation of newborn infants.

BACKGROUND This section is under preparation and will be included in the next issue. OBJECTIVES The purpose of the review was to compare the complications associated with intubation by the nasal route with those associated with intubation by the oral route for mechanical ventilation in newborn infants. SEARCH STRATEGY The standard search strategy of the Neonatal Review Group as outlined in the Cochrane Library was used. This included searches of the Oxford Database of Perinatal Trials, Cochrane Register of Controlled Trials, MEDLINE and CINAHL. A call was placed on the list servers, NICU-NET and Neonatal Talk for unpublished trials, conference presentations and current trials. SELECTION CRITERIA All trials using random or quasi-random allocation of patients to either the nasal or oral route of intubation were included. Study quality and eligibility were assessed independently by each author. DATA COLLECTION AND ANALYSIS The standard method of the Cochrane Collaboration and the Neonatal Review Group was used to assess the methodological quality of the included studies. The methodological quality of each study was reviewed by the second author blinded to study authors and institutions. Each reviewer extracted data separately before comparison and resolution of differences. The standard method of the Neonatal Review Group was used to measure the effect of the different routes of intubation, using Relative Risk (RR) and 95% Confidence Intervals (CI). MAIN RESULTS Only two eligible randomized trials were found. Data from these two trials failed to show significant differences between the oral and nasal route of intubation for mechanically ventilated neonates. The rate of failure to intubate using the nasal route was higher in one study. One study found post extubation atelectasis occurred more frequently in nasally intubated infants who weighed less than 1500 grams. The rates of malposition of the tube at the initial intubation, accidental extubation, tube blockage, re-intubation after extubation, septicaemia, clinical infection and local trauma (nasal erosion or palatal groove) were not significantly different for the two groups. REVIEWER'S CONCLUSIONS Post extubation atelectasis may be more frequent after nasal intubation, particularly in very low birth weight infants. One route of intubation does not seem to be preferable to the other. There is a need for further randomized controlled trials containing larger numbers of infants.
Compliance with IAS/IFRS and its Determinants: A Meta-Analysis

The objective of this paper is to meta-analyze a set of 1? empirical papers dealing with the determinants of the degree of compliance with IASXIPRS standards. We consider firm size (proxy for agency theory), profitability [proxy for signaling theory), leverage (proxy for agency and signaling theories), auditor (proxy signaling theory), internationality (proxy for capital need theory), and ownership diffusion (proxy for agency theory). Our results provide evidence that firm size, auditor type, multi~ nationality, proﬁtability and ownership dispersion have a positive effect on IASXIFRS compliance. Compliance with IAS/IFRS in emerging markets is suongly associated vnth firm size, auditor type, leverage, profitability and ownership dispersion. Given the low disclosure envnonment, weak investors’ protection and capital external need prevailing in these contexts; these factors are likely to enhance corporate reporting policy. -Managers comply seriously with LAS/IFRS in developing countries to reduce agency costs, signal a higher financial statements’ credibility and get more easily external finance from financial institutions. Compliance with IASXIPRS in developed countries is associated with corporate size, audit firm size and muiti-nationality. In addition, investor protection level also moderates the association between corporate characteristics and compliance IAS/IFRS. For instance, in low investor protection settings, corporate size and profitability are more associated with LAS/IFRS compliance, while audit firm size, leverage and multi-nationa.lity increase the degree of compliance with IAS/IPRS in countries characterized by high protection level. The ﬁnding:-: emphasize the need to explicitly consider the legal and institutional setting when one analyzes the effect of corporate characteristics on IASXIFRS compliance.
Firearms legislation and reductions in firearm-related suicide deaths in New Zealand.

OBJECTIVE To examine the impact of introducing more restrictive firearms legislation (Amendment to the Arms Act, 1992) in New Zealand on suicides involving firearms. METHOD National suicide data were examined for 8 years before, and 10 years following the introduction of the legislation. RESULTS After legislation, the mean annual rate of firearm-related suicides decreased by 46% for the total population (p < 0.0001), 66% for youth (15-24 years; p < 0.0001) and 39% for adults (> or = 25 years; p < 0.01). The fraction of all suicides accounted for by firearm-related suicides also reduced for all three populations (p < 0.0001). However, the introduction of firearms legislation was not associated with reductions in overall rates of suicide for all three populations. CONCLUSIONS Following the introduction of legislation restricting ownership and access to firearms, firearm-related suicides significantly decreased, particularly among youth. Overall rates of youth suicide also decreased over this time but it is not possible to determine the extent to which this was accounted for by changes in firearms legislation or other causes.
Assessment of thermoregulatory and postprandial thermogenesis over the first 24 hours after birth in pigs

Heat production was continuously measured from birth to 24 h after birth in pigs tube‐fed 14 g kg‐1 of colostrum or water (sham‐fed animals) at hourly intervals, and maintained at thermoneutrality (34 degrees C) or in moderate cold (24 degrees C). Results indicate that colostrum was necessary to initiate and sustain the postnatal rise in metabolic rate observed at 34 degrees C. It provided about 75% of the energy required for heat production at 24 degrees C. Heat production was increased by 74% in the cold and decreased by 30% during starvation. In both cases, maintenance of the energy balance was achieved with a compensatory drop in body temperature. At 34 degrees C, variations in postmeal heat production represented 12% of the total 24 h energy expenditure and were almost equally due to the thermogenic effect of colostrum and to confounding factors, including physical activity. In the cold, calculated postmeal thermogenesis accounted only for 3% of 24 h energy expenditure and for 9% of the extra heat produced in the cold. Our results highlight the main role of colostral energy in the energy metabolism of the newborn pig in a typical birth environment (24 degrees C) and in thermoneutral conditions (34 degrees C). Thermoneutral postmeal thermogenesis is low and its contribution to the extra heat produced in the cold very limited.
Magnetic Birefringence and Dichroism in Magnetic Fluid

The magneto-optical effect in magnetic fluids is investigated. The phase difference ¿ between the ordinary ray and the extraordinary ray transmitted through the magnetic fluid thin film, was found to be described by the functional form ¿1f(H)/[T-T1 +f(H)], where H is the magnetic field applied to the magnetic fluid film, T is the absolute temperature of the film, f(H) is a certain increasing function of H, and T1 and ¿1 are positive constants. The field dependence of the optical transmissivity of magnetic fluid thin films is well described by the cluster model of ferrous colloidal particles in the applied field direction when the aggregation is small. The field dependence of transmissivity is, however, explained neither by the electric absorption of the clusters, nor by the Rayleigh scattering when the cluster becomes larger. The effect of diffraction by linear clusters oriented by the applied field must be taken into account in explaining the optical extinction.

Listening to the Buzz: Social Media Sentiment and Retail Depositors' Trust

We investigate the relationship between the rumours on Twitter regarding banks and deposits growth. The sentiment expressed in tweets is analysed and employed for the nowcasting of retail deposits. We show that a Twitter-based indicator of sentiment improves the predictions of a standard benchmark model of depositor discipline based on financial data. We further improve the power of the model introducing a Twitter-based indicator of perceived interconnection, that takes into account spillover effects across banks.
