A progressive edge growth algorithm for bit mapping design of LDPC coded BICM schemes (2016)

In this paper, we consider the design of the bit mapping in low-density parity-check (LDPC) coded bit-interleaved coded modulation (BICM) schemes. We introduce a two-layer bipartite graph to represent the LDPC coded BICM scheme where a new bit mapping graph linking sub-channels to variable nodes (VNs) is added to the conventional Tanner graph. We propose a progressive edge growth (PEG) algorithm to design the bit mapping for the BICM scheme. The design paradigm is to provide more protections to the VNs that are allocated to the sub-channels with the lowest mutual information. We define a novel concept of unreliable depth profile to classify the reliability of the VNs. By connecting more reliable edges to the least reliable VNs, we can significantly improve the reliable edge distribution for the unreliable VNs, thus improve the extrinsic information in the iterative decoding. The proposed bit mapping algorithm is employed for the design of the LDPC coded BICM with 64-QAM and 256-QAM. Simulation results show that the proposed design can considerably improve the error performance, compared to the conventional consecutive bit mapping strategy.
Pervasive health care applications face tough security challenges (2002)

The explosive growth of pervasive computing in medicine has begun to produce many useful applications, systems, and tools. The legal environment in which these tools must operate is rapidly evolving, so procedures must be developed to effectively comply with the law and regulations now in preparation. As in the PC's early days, many isolated tools are emerging that have great potential. But these need additional integration, security, and standards work, especially to protect confidential medical records data, to realize their full potential while protecting the organizations and end users that employ them.
Influence of surface modifications and channel structure for microflows of supercritical carbon dioxide and water (2015)

Miniaturization offers a possibility to increase the performance and decrease the time scales of systems. Existing microsystems using supercritical CO2 mainly utilizes multiphase segmented flows. To allow for a broader toolbox for future systems, also parallel flows are useful which eases the separation of the different phases. Here, the effect of different surface coatings are studied for multiphase flows of scCO2 and H2O in flat microchannels, with and without a 4 μm high ridge guide, which allows for pinning of the fluid interface inside the 190 μm wide and 35 μm high channel. Three different surfaces with different wettings toward scCO2 and H2O are studied, where a surface terminated with a hydrocarbon-based silane was observed to be neutral in the H2O/scCO2 system, a surface terminated with a fluorocarbon-based silane was hydrophobic, and an uncoated glass surface was hydrophilic. Using two flow rates of 5:5 μl/min (CO2:H2O) and 6.5:3.5 μl/min (CO2:H2O), a parallel flow between scCO2 and H2O was observed for uncoated and flat channels where the H2O flow pushed the CO2 to the side, before the flows eventually breaks up into segments. With a ridge guide in the middle of the channel, the interface was pinned at half the channel width, although still breaking up into segments. The neutral hydrocarbon-based surface coating with approximately 90° contact angles resulted in evenly created segments without a ridge guide. Including a guide in the middle of the channel, a parallel flow was observed throughout the channel, although occasionally small CO2 segments entered the H2O outlet. Using the fluorocarbon-based silane resulted in an unstable segmented system with pressure fluctuations. Using surface modifications, an increased control can be achieved for either segmentation or parallel flow where a neutral surface is favored for a stable flow behavior. Together with a ridge guide, the fluid interface was pinned at the center.
VOLUME DETERMINATION OF A VACUUM VESSEL BY PRESSURE RISE METHOD (2009)

Abstract ─ A new method for determination of volume ratios and also the absolute value of volumes of vacuum vessels is presented. Method is based on a measurement of rate of pressure rise in a vacuum chamber at constant flow of inert gas. An example of measurement of a volume of a chamber with a nominal volume of 7 L is presented. For pressure measurements we have used a spinning rotor gauge (SRG) and He permeation leak was used as a gas source.
Ketotifen in the treatment of changes of the upper part of digestive tract in allergic children. (1995)

The aim of our study was the endoscopic assessment of the oesophagus, stomach and duodenal mucosa in 42 allergic children aged 2-16 years with chronic abdominal complaints. We also attempted to assess Ketotifen efficacy in a selected group of 36 allergic children with different stages of inflammatory changes, including peptic ulcer. A control endoscopic examination was performed after 2, 4, 6, 8 weeks of Ketotifen treatment. A favourable effect of the application of Ketotifen was observed.
The role of the nuclear protein matrix during development of rabbit gr anulocytes (1981)

A proteinaceous nuclear substructure (nuclear protein matrix or nuclear pore complex-lamina) has been described in a number of cells and may be a universal feature of cell nuclei. We have investigated the nuclear protein matrix (NPM) in the rabbit blood granulocyte and its precursor cells to determine (A) whether the NPM composition is similar to other cells that have been studied and (B) to determine whether the dramatic morphological changes that the granulocyte nucleus undergoes during cell maturation are related to changes in the composition or structure of the NPM. NPM preparations from rabbit granulocytes were similar but not identical to those found in HeLa cells or rat liver nuclei. The NPM structure of more mature cells retained more DNA during the isolation procedures than did immature cell NPMs, and the DNA was less accessible to DNAse in the mature cell nuclei. Scanning and transmission electron microscopy revealed a continuous outer covering of the NPM preparation and a lattice-like internal structure. Recognizable nuclear form persisted although the preparations represented less than 20% of the original nuclear protein. NPM preparations from mature cells were similar in overall dimensions and internal structure to NPM from immature cells, suggesting reexpansion during isolation of a previously compacted NPM structure in segmented neutrophils. NPM proteins are synthesized primarily in early stages of cell development. The NPM appears to play a major, but passive, structural role in the nuclear changes observed during maturation of granulocytes.
Determining the Effects of Lipophilic Drugs on Membrane Structure by Solid-State NMR Spectroscopy: The Case of the Antioxidant Curcumin (2009)

Curcumin is the active ingredient of turmeric powder, a natural spice used for generations in traditional medicines. Curcumin's broad spectrum of antioxidant, anticarcinogenic, antimutagenic, and anti-inflammatory properties makes it particularly interesting for the development of pharmaceutical compounds. Because of curcumin's various effects on the function of numerous unrelated membrane proteins, it has been suggested that it affects the properties of the bilayer itself. However, a detailed atomic-level study of the interaction of curcumin with membranes has not been attempted. A combination of solid-state NMR and differential scanning calorimetry experiments shows curcumin has a strong effect on membrane structure at low concentrations. Curcumin inserts deep into the membrane in a transbilayer orientation, anchored by hydrogen bonding to the phosphate group of lipids in a manner analogous to cholesterol. Like cholesterol, curcumin induces segmental ordering in the membrane. Analysis of the concentration dependence of the order parameter profile derived from NMR results suggests curcumin forms higher order oligomeric structures in the membrane that span and likely thin the bilayer. Curcumin promotes the formation of the highly curved inverted hexagonal phase, which may influence exocytotic and membrane fusion processes within the cell. The experiments outlined here show promise for understanding the action of other drugs such as capsaicin in which drug-induced alterations of membrane structure have strong pharmacological effects.
Coercivity distribution of Co-modified ferrites (1987)

A new theoretical approach is proposed, which quantitatively describes the origin of the coercivity enhancement and the specific shape of the coercivity distribution curves of Co surface treated iron oxide pigments. Within the model the dependence of the coercivity distribution on the morphology, on the magnetic properties of the original precursor and on the surface treatment process is deduced.
An overview of available and emerging 3D video formats and depth enhanced stereo as efficient generic solution (2009)

Recently, popularity of 3D video has been growing significantly and it may turn into a home user mass market in the near future. However, diversity of 3D video content formats is still hampering wide success. An overview of available and emerging 3D video formats and standards is given, which are mostly related to specific types of applications and 3D displays. This includes conventional stereo video, multiview video, video plus depth, multiview video plus depth and layered depth video. Features and limitations are explained. Finally, depth enhanced stereo (DES) is introduced as a flexible, generic, and efficient 3D video format that can unify all others and serve as universal 3D video format in the future.
Underdetermined Convolutive Blind Source Separation via Time–Frequency Masking (2009)

In this paper, we consider the problem of separation of unknown number of sources from their underdetermined convolutive mixtures via time-frequency (TF) masking. We propose two algorithms, one for the estimation of the masks which are to be applied to the mixture in the TF domain for the separation of signals in the frequency domain, and the other for solving the permutation problem. The algorithm for mask estimation is based on the concept of angles in complex vector space. Unlike the previously reported methods, the algorithm does not require any estimation of the mixing matrix or the source positions for mask estimation. The algorithm clusters the mixture samples in the TF domain based on the Hermitian angle between the sample vector and a reference vector using the well known <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</i> -means or fuzzy <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</i> -means clustering algorithms. The membership functions so obtained from the clustering algorithms are directly used as the masks. The algorithm for solving the permutation problem clusters the estimated masks by using <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</i> -means clustering of small groups of nearby masks with overlap. The effectiveness of the algorithm in separating the sources, including collinear sources, from their underdetermined convolutive mixtures obtained in a real room environment, is demonstrated.
A research on reconfigurable numerical controller based on embedded system (2006)

By analyzing the current development of reconfigurable numerical controllers (RNC) and architecture about numerical controllers, this paper presents a RNC architecture based on an embedded system, and analyzes the hardware and software structure of the RNC system. In the hardware structure, it discusses the multifunctional interfaces of MPC5200, and emphasizes configurable hardware functions. In the software structure, this paper first introduces the architecture of the RNC system, then the three layers of the RNC system: user layer, kernel layer and device layer, which have been designed with the character of modularity, extensibility and configurability. Furthermore, embedded Linux and RTAI also have been selected as compact, open, and real-time operating system for RNC. Finally a case is presented to illustrate how to realize the RNC in the cutting machine
HIV infection perturbs interleukin-7 signaling at the step of STAT5 nuclear relocalization (2011)

HIV infection perturbs IL-7 signaling by impairing the access of STAT5 to the nuclear compartment. This defect may contribute to the loss of CD4(+) T-cell populations in patients with chronically high immune activation.
Automatic keyword extraction for the meeting corpus using supervised approach and bigram expansion (2008)

In this paper, we tackle the problem of automatic keyword extraction in the meeting domain, a genre significantly different from written text. For the supervised framework, we proposed a rich set of features beyond the typical TFIDF measures, such as sentence salience weight, lexical features, summary sentences, and speaker information. We also evaluate different candidate sampling approaches for better model training and testing. In addition, we introduced a bigram expansion module which aims at extracting ldquoentity bigramsrdquo using Web resources. Using the ICSI meeting corpus, we demonstrate the effectiveness of the features and show that the supervised method and the bigram expansion module outperform the unsupervised TFIDF selection with POS (part-of-speech) filtering. Finally, we show the approaches introduced in this paper perform well on the speech recognition output.
Management of Single‐Ventricle Patients With Berlin Heart EXCOR Ventricular Assist Device: Single‐Center Experience (2012)

There are minimal data regarding chronic management of single-ventricle ventricular assist device (VAD) patients. This study aims to describe our center's multidisciplinary team management of single-ventricle patients supported long term with the Berlin Heart EXCOR Pediatric VAD. Patient #1 was a 4-year-old with double-outlet right ventricle with aortic atresia, L-looped ventricles, and heart block who developed heart failure 1 year after Fontan. She initially required extracorporeal membrane oxygenation support and was transitioned to Berlin Heart systemic VAD. She was supported for 363 days (cardiac intensive care unit [CICU] 335 days, floor 28 days). The postoperative course was complicated by intermittent infection including methicillin-resistant Staphylococcus aureus, intermittent hepatic and renal insufficiencies, and transient antithrombin, protein C, and protein S deficiencies resulting in multiple thrombi. She had a total of five pump changes over 10 months. Long-term medical management included anticoagulation with enoxaparin, platelet inhibition with aspirin and dipyridamole, and antibiotic prophylaxis using trimethoprim/sulfamethoxazole. She developed sepsis of unknown etiology and subsequently died from multiorgan failure. Patient #2 was a 4-year-old with hypoplastic left heart syndrome who developed heart failure 2 years after bidirectional Glenn shunt. At systemic VAD implantation, he was intubated with renal insufficiency. Post-VAD implantation, his renal insufficiency resolved, and he was successfully extubated to daytime nasal cannula and biphasic positive airway pressure at night. He was supported for 270 days (CICU 143 days, floor 127 days). The pump was upsized to a 50-mL pump in May 2011 for increased central venous pressures (29 mm Hg). Long-term medical management included anticoagulation with warfarin and single-agent platelet inhibition using dipyridamole due to aspirin resistance. He developed increased work of breathing requiring intubation, significant anasarca, and bleeding from the endotracheal tube. The family elected to withdraw support. Although both patients died prior to heart transplantation, a consistent specialized multidisciplinary team approach to the medical care of our VAD patients, consisting of cardiothoracic surgeons, heart transplant team, hematologists, pharmacists, infectious disease physicians, psychiatrists, specialty trained bedside nursing, and nurse practitioners, allowed us to manage these patients long term while awaiting heart transplantation.
An empirical table-based FET model (1999)

A new large-signal FET model combining empirical and table-based models was developed and investigated experimentally. The Chalmers empirical model was used as an envelope for the measured data for main parameters of the model. Combining empirical and table-based models improves accuracy and simplifies as well as speeds extraction. The procedure can be applied for other types of devices.
Nitrogen-Fireable Resistors: Emerging Technology for Thick-Film Hybrids (1987)

An extensive technology transfer program to move this technology from the research laboratory to full commercial availability is under way. The environmental stability of 44 lots made in pilot, prototype, and manufacturing scale runs have been evaluated and confirm lot-to-lot reproducibility. Lanthanum boride members show good environmental stability under all conditions. Doped tin oxide members are humidity sensitive and require encapsulation. When encapsulated with an organic material, all grades show maximum changes of less than one percent after 1000 h of exposure to 85°C/85percent relative humidity.
Sodium alginate/heparin composites on PVC surfaces inhibit the thrombosis and platelet adhesion: applications in cardiac surgery. (2013)

Thrombosis and hemocyte damage are the main problems of applied non-coated biomaterials to cardiac surgery that remain unsolved. The present study is aimed at the chemical modification of polyvinyl chloride (PVC) for applications in cardiac surgery and the biological property assessment of modified PVC. Sodium alginate (SA)/heparin (HEP) composites were covalently immobilized onto the surface of the PVC pipeline. The surface grafting density and protein adsorption were determined by ultraviolet spectrophotometry. The surface contact angles were evaluated by contact-angle measurement, whereas the surface characteristics were evaluated by Fouriertransform infrared spectroscopy. Blood coagulation time and platelet adhesion were measured using an automated blood coagulation analyzer and a hemocytometer, respectively. Surface morphologies of the thrombus and platelets were evaluated by scanning electron microscopy. The immobilization of SA/HEP reduced the contact angles of the coated surface. Protein adsorption was reduced by the immobilization of SA. The activated partial thrombin time and thrombin time of the coated PVC were significantly prolonged as compared with the non-coated PVC. Platelet adhesion and thrombus formation were all reduced by the immobilization of HEP. The results revealed that the SA/HEP coating can improve the antithrombogenicity of the PVC pipeline, as well as improve its biocompatibility and hemocompatibility, which are essential for cardiac pulmonary bypass surgery.
Advanced calibration to improve robustness of drone-acquired hyperspectral remote sensing data (2017)

Airborne hyperspectral remote sensing is becoming increasingly integrated into monitoring and management applications on large spatial scales. The main advantage of hyperspectral remote sensing is the high spectral resolution, which enables classification/separation of objects, which may appear very similar to the human eye. An example of similar objects is growing agricultural crops with/without emerging pest infestations. In agricultural fields, accurate detection of hotspots with emerging pest infestations can be used to optimize precision-agriculture such as spot treatments with pesticides and/or spatio-temporal releases of natural enemies to control pest species. Despite the significant potential associated with the integration of airborne remote sensing into monitoring and management of crops in agriculture, and many other industry sectors, the widespread use of airborne hyperspectral remote sensing data is constrained by a critically important challenge the non-linear dynamics of weather, source-sensor geometry, solar light intensity, and scattering. That is, the sensitivity of hyper-spectral remote sensing data is, on one hand, the clear advantage of this technology, but it is also its limitation unless it is possible to correct the radiometric signals and minimize the effects of varying weather, goniometry, solar illumination, and scattering. Under the assumption of correcting airborne hyperspectral remote sensing data, it is possible to acquire “pure” reflectance profiles from target objects. Such advanced reflectance calibration of airborne remote sensing data to obtain “pure” hyperspectral reflectance will greatly improve both the robustness of input data and the sensitivity of classification algorithms.
