Watermarking of Free-view Video (2010)

With the advances in image based rendering (IBR) in recent years, generation of a realistic arbitrary view of a scene from a number of original views has become cheaper and faster. One of the main applications of this progress has emerged as free-view TV(FTV), where TV-viewers select freely the viewing position and angle via IBR on the transmitted multiview video. Noting that the TV-viewer might record a personal video for this arbitrarily selected view and misuse this content, it is apparent that copyright and copy protection problems also exist and should be solved for FTV. In this paper, we focus on this newly emerged problem by proposing a watermarking method for free-view video. The watermark is embedded into every frame of multiple views by exploiting the spatial masking properties of the human visual system. Assuming that the position and rotation of the virtual camera is known, the proposed method extracts the watermark successfully from an arbitrarily generated virtual image. In order to extend the method for the case of an unknown virtual camera position and rotation, the transformations on the watermark pattern due to image based rendering operations are analyzed. Based upon this analysis, camera position and homography estimation methods are proposed for the virtual camera. The encouraging simulation results promise not only a novel method, but also a new direction for watermarking research.
Changes in Pigments, Chlorophyllase Activity, and Chloroplast Ultrastructure in Ripening Pepper for Paprika (1996)

Two typical cultivars of pepper for paprika (Bola Roja of red fruits and Negral of brownish fruits) were analyzed for pigments, chlorophyllase activity, and plastid ultrastructure. Three ripening stages were considered: green, unripe (changing color), and fully ripe. Fully ripe peppers of the Negral cultivar retained chlorophyll, while in the Bola Roja fruits this disappeared at the end of maturation. Chlorophyllase activity was higher in the cv. Negral at the first two ripening stages, and similar in both cultivars at the fully ripe stage. Plastids of the early ripening stage were characterized by the typical grana−intergranal structure and a highly developed peripheral reticulum. In the last stage, plastids presented massive structural reorganization. All of these differences among both cultivars are discussed. Keywords: Capsicum annuum; carotenoids; chlorophyllase; ultrastructure
Role of the brain in the control of erection (2006)

In contrast to the spinal control of erection, relatively little is known about the brain control. In the present review, we have outlined the role of brain structures involved in penile erection and provided a synopsis on the brain circuit of erection. Findings from both animal and human studies are discussed. Evidence suggests that the most important structures are the frontal lobe, cingulate gyrus, amygdala, thalamus and hypothalamus. Within the brain circuit of erection, the thalamus serves as a gate-controller in which all relevant information is evaluated and further processed to higher and lower centres.
High-density high-reliability tungsten interconnection by filled interconnect groove metallization (1988)

A novel multilevel metallization scheme has been developed that uses tungsten for the primary level of interconnection. Grooves that are 1- mu m wide and 2.0- mu m deep, corresponding to a level of line conductor interconnection, are pattern-etched into a planar layer of oxide dielectric. They are filled by isotropically depositing a blanket layer of pure tungsten using low-pressure chemical vapor deposition (CVD), followed by etch-back of the tungsten to produce a filled-interconnection-groove (FIG) conductor structure. Fabricated FIG conductors display an average sheet resistivity of 48 m Omega /square, comparable to conventional aluminum conductors. In addition, FIG metallization provides excellent planarity and greatly improved electromigration strength, and it facilitates the use of stacked vias.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The costs of adverse drug events in hospitalized patients. Adverse Drug Events Prevention Study Group. (1997)

The substantial costs of ADEs to hospitals justify investment in efforts to prevent these events. Moreover, these estimates are conservative because they do not include the costs of injuries to patients or malpractice costs.
Metadata and Modeling Frameworks: The Object Modeling System Example (2004)

The main motivation for the usage of modeling frameworks for environmental simulation software is to manage and simplify the interoperability of (loosely) coupled simulation components. Conventional approaches in collaboration are using an Application Programming Interface (API). Recent developments in simulation frameworks focus on introspecting architectures for simulation components, where components become passively explored and integrated in to the framework. Such solutions seem to be more flexible to support the framework evolution because components are less tight to a specific framework API. The Object Modeling System (OMS) is an introspecting simulation framework, which uses metadata in annotated components such as (i) spatial and temporal constraint specification, (ii) data annotation for variables and parameters to specify simulation related data like runtime constraints for range validation, unit conversion, or automated testing. The OMS utilizes metadata annotation (i) at model construction time to support proper spatial and temporal model assembly (ii) and at model runtime to support proper data linkage. This paper will emphasize on metadata access to support model linkage to simplify the development of simulation components for environmental scientists and will give application examples based on the Object Modeling System
Basic Studies for Modeling Complex Weft Knitted Fabric Structures Part V: Geometrical Modeling of Tuck Stitches (2008)

In this work the geometrical model of a tuck stitch and its effect on the plain knitted fabric structure are introduced. The geometrical model of this knit + tuck combination is created here for the first time, being a pioneering basic work on knit + tuck combinations. This model is then plotted using 3DS Max software. It is shown that the obtained shapes are exactly the same shapes observed in real fabrics.
Demand Responsive Mobility as a Service (2016)

Fundamental requirements in mobility are time, cost and comfort. Individual car ownership satisfies comfort component and to some extent, the time component as well. However, owning and maintaining a car is prohibitive for many due to cost and convenience implications. In selecting other public modes of transportation, a taxi or rental car would provide a more comfortable ride with little to none waiting time and conforms to the passengers mobility requirements. However, the cost is too high and cannot be sustained as a regular mode of transport. On the other hand, shared public transport such as bus or train is more affordable but requires the passenger to conform their schedule to a set timetable that operates no matter the changes in demand. In developing countries, however, the shared public transport alternatives do not have timetables and waiting time could be up to an hour. Recent research in shared mobility systems, specifically Demand Responsive Transport (DRT), addresses this situation. Solutions to DRT trip scheduling are constrained to the variation of DRT specifications but does not vehicle schedule and quorum specifications considerations. We aim to reduce passenger waiting time for shared mobility and propose a design of a DRT-based Demand Responsive MaaS (Mobility as a Service) model that provides centralized management and ICT support. Our design adds time constraints of vehicle schedule to the DRT problem. We propose a trip scheduling and cost sharing algorithm for our designed model and base our approach on a DRT heuristic algorithm and a quorum to enforce a minimum demand. A simulation experiment showed average waiting time reduced by 44.4% compared to other DRT time optimization solutions. We conducted a pilot study in Dhaka, Bangladesh for 4 months. Actual average waiting time reduced to 25% compared to current public transport in Dhaka.

An experimental analysis on how the dead-time of SiC BJT and SiC MOSFET impacts the losses in a high-frequency resonant converter (2014)

Active control of the dead-time in a SLR converter is in this paper shown to be of great importance. The efficiency of the full-bridge will increase if the dead-time control is made in the right way. Different control algorithms are shown to work well for different power switches. For the SiC MOSFET and the SiC BJT the control algorithms are tested experimentally.
Cost effectiveness of the multichannel cochlear implant. (1995)

Although most third-party payors presently fund cochlear implantation, some do not, and many cite the current lack of cost-effectiveness data as a major concern. Cost-utility analysis is a widely used method of medical technology assessment that permits cost-effectiveness comparisons between medical interventions by determining the cost per quality-adjusted life-year (QALY) they provide. The cost per QALY for the cochlear implant was determined using clinical cost data and a health-utility outcome model based on the established communication gains attained with the device. Cochlear implantation costs approximately $15,600 per QALY provided. Sensitivity analysis, a technique that systematically varies the assumptions underlying the calculations, favorably with other medical interventions, such as coronary artery bypass grafting ($10,431) for three-vessel disease, $64,033 for single-vessel disease), the implantable defibrillator ($29,200), and cardiac transplantation ($38,970). This analysis indicates that the cochlear implant lies well within the cost-effectiveness range currently accepted by the American medical system.

Evolution and integration of a multi-media communications network (2003)

A possible scenario is considered for the evolution of the public switched network to serve the communication needs of multimedia terminals. The authors explain how the local-area network (LAN) is evolving toward the metropolitan-area network (MAN) and the wide-area network (WAN), which can interconnect multiple LANs and high-speed workstations dispersed in different parts of a metropolitan area. They then describe the evolution of the ISDN provide high-speed communication services such as video, and in addition, the evolution of the X.25 packet network toward the frame-relaying network. Such a network improves the throughput/delay performance of the data network. It is concluded that these different evolutionary paths should eventually converge to the next generation switching system that will provide integrated voice/data/image/video capabilities.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Scrub Typhus in a Tertiary Care Hospital in the Eastern Part of Odisha (2015)

Our hospital, tertiary care hospital in the capital of the State of Odisha, had been witnessing pyrexia of unknown origin, associated with breathlessness, renal and liver impairment, which did not respond to high antibiotics like Carbapenems but to Doxycycline therefore, the present study was undertaken to identify whether scrub typhus is the aetiological agent and thereafter their characteristic features were further evaluated as an effort in supporting its diagnoses and treating patients accordingly. 150 Adult patients (age >12 yrs) admitted with pyrexia of unknown origin between April 2011 and October 2013, were evaluated. Weil Felix test was done in all these patients. Weil Felix positive samples were tested for Scrub Typhus IgM ELISA. Of the 150 patients included in the study 50 (33.33%) were found to be positive for IgM antibodies against Orientia Tsutsugamushi. The cases were seen mainly in the months between September and November. The common symptoms found were fever, myalgia, breathlessness, rash and abdominal pain and clouding of memory. The diagnostic features like eschar were found in 32% patients. Nearly two thirds of patients had fever >30 days and myalgia (62.5%), breathlessness (64%). Most common complications was ARDS (62.5%) followed by liver and renal failure (50%). Our results showed that Scrub typhus should be considered in the differential diagnosis of POU associated with breathlessness, myalgia, rash, gastrointestinal symptoms, hepatorenal syndrome or ARDS. Empirical treatment with Doxycycline may be given in the cases with strong suspicion of Scrub typhus.
Endogenous presenilin 1 redistributes to the surface of lamellipodia upon adhesion of Jurkat cells to a collagen matrix (1999)

Most familial early-onset Alzheimer's disease cases are caused by mutations in the presenilin 1 (PS1) gene. Subcellular localization of the endogenous PS1 is essential for understanding its function, interactions with proteins, and role in Alzheimer's disease. Although numerous studies revealed predominant localization of PS1 to endoplasmic reticulum and Golgi, there are conflicting reports on the localization of PS1 to the cell surface. We found that endogenous PS1 is highly expressed in T lymphocytes (Jurkat cells). Using a variety of methods, we present evidence that endogenous PS1 is localized to the cell surface in addition to intracellular membrane compartments. Moreover, PS1 appeared in high levels on the surface of lamellipodia upon adhesion of the cells to a collagen matrix. The redistribution of PS1 in adhered cells was strikingly similar to that of the well characterized adhesion protein CD44. Cell surface PS1 formed complexes in vivo with actin-binding protein filamin (ABP-280), which is known to form bridges between cell surface receptors and cytoskeleton and mediate cell adhesion and cell motility. Taken together, our results suggest a role of PS1 in cell adhesion and/or cell-matrix interaction.
Characteristics of long-term survivors in a randomized phase III trial (NAPOLI-1) of patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) treated with liposomal irinotecan (nal-IRI; MM-398) + 5-FU/LV. (2017)

293 Background: nal-IRI, a liposomal formulation of irinotecan, plus 5-FU/LV is approved in the United States and Taiwan for patients (pts) with mPDAC previously treated with gemcitabine-based therapy. Primary analysis of the NAPOLI-1 trial (NCT01494506) showed that nal-IRI+5-FU/LV significantly improved median overall survival vs 5-FU/LV (6.1 vs 4.2 months; HR, 0.67; 95% CI, 0.49-0.92; P = 0.012; Wang-Gillam et al, Lancet. 2016). Herein we report baseline characteristics of pts surviving ≥1 year (data cutoff, Nov 2015). Methods: This analysis includes 117 pts assigned to treatment with nal-IRI 70 mg/m 2 (free base) + 5-FU/LV 2400/400 mg/m 2 q2w, and 119 pts assigned to treatment with 5-FU/LV 2000/200 mg/m 2 weekly for weeks 1-4 q6w. Results: A total of 29 (25%) pts in the nal-IRI+5-FU/LV arm and 17 (14%) in the 5-FU/LV arm survived ≥1 year. These pts typically had better performance status, lower CA19-9 (U/mL) levels, and were less likely to have liver metastases at baseline, compared with the overall population (Table). For long-term survivors in the nal-IRI+5-FU/LV arm, a higher proportion of pts had neutrophil-to-lymphocyte ratio (NLR) >5, a marker of poor prognosis, suggesting that higher NLR may potentially be predictive of survival outcome with nal-IRI+5-FU/LV. Conclusions: More pts receiving nal-IRI+5-FU/LV versus 5-FU/LV were alive beyond 1 year. The most prominent prognostic markers of survival ≥1 year included lower CA19-9, KPS ≥90 and absence of liver metastases. These analyses may be limited by small sample sizes. Clinical trial information: NCT01494506. [Table: see text]
A multiple layer contour-based gridless channel router (1990)

An n-layer gridless channel router is presented. Instead of the commonly used grid it uses a set of contours as a routing framework. The contours, together with a set of reserved areas, present short circuits and ensure routability of all nets. A compact routing can be expected, since the framework is a very adequate model of the physical channel. It is shown that this router is also versatile enough to handle the classic vertical constraint problem. The inherent flexibility enables a design rule driven tradeoff between the number of vias, the wire length, and the channel height. The behavior of the algorithm has been investigated for many different channels, including the well-known difficult example and its recent derivatives. Very competitive results have been achieved for channel height and via count.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Vital Signs: Estimated Effects of a Coordinated Approach for Action to Reduce Antibiotic-Resistant Infections in Health Care Facilities — United States (2015)

Improving H.264 video coding through block oriented transforms (2008)

This paper introduces a pre-processing stage for the video coder H.264/MPEG4-AVC that takes advantage of the orientation of the blocks. Contrary to most of the proposed solutions in the literature, it is not the transform that adapts to the signal but the signal that is pre-processed to dasiafitpsila the transform. Residual blocks are straightened out to horizontal or vertical axes with the help of circular shifts applied at the pixel level. These shifts allow to simulate pseudo-rotations in the blocks. They are defined for all the partition sizes (16times16 to 4times4) and the two integer transforms of H.264 (8times8 and 4times4). Size and orientation for the blocks are evaluated with the help of a selection based on a rate-distortion criterion. This pre-processing stage applied on residual frames of a H.264 coder can improve its rate-distortion performances.
