Computer Vision (2011)

The typical computational approach to object understanding derives shape information from the 2D outline of the objects. For complex object structures, however, such a planar approach cannot determine object shape; the structural edges have to be encoded in terms of their full 3D spatial configuration. Computer Vision: From Surfaces to 3D Objects is the first book to take a full approach to the challenging issue of veridical 3D object representation. It introduces mathematical and conceptual advances that offer an unprecedented framework for analyzing the complex scene structure of the world. An Unprecedented Framework for Complex Object RepresentationPresenting the material from both computational and neural implementation perspectives, the book covers novel analytic techniques for all levels of the surface representation problem. The cutting-edge contributions in this work run the gamut from the basic issue of the ground plane for surface estimation through mid-level analyses of surface segmentation processes to complex Riemannian space methods for representing and evaluating surfaces. State-of-the-Art 3D Surfaceand Object RepresentationThis well-illustrated book takes a fresh look at the issue of 3D object representation. It provides a comprehensive survey of current approaches to the computational reconstruction of surface structure in the visual scene.
Liver X Receptor Signaling Pathways and Atherosclerosis (2010)

First discovered as orphan receptors, liver X receptors (LXRs) were subsequently identified as the nuclear receptor target of the cholesterol metabolites, oxysterols. There are 2 LXR receptors encoded by distinct genes: LXRalpha is most highly expressed in the liver, adipose, kidney, adrenal tissues, and macrophages and LXRbeta is ubiquitously expressed. Despite differential tissue distribution, these isoforms have 78% homology in their ligand-binding domain and appear to respond to the same endogenous ligands. Work over the past 10 years has shown that the LXR pathway regulates lipid metabolism and inflammation via both the induction and repression of target genes. Given the importance of cholesterol regulation and inflammation in the development of cardiovascular disease, it is not surprising that activation of the LXR pathway attenuates various mechanisms underlying atherosclerotic plaque development. In this brief review, we will discuss the impact of the LXR pathway on both cholesterol metabolism and atherosclerosis.
Sensitivity studies for quantitative assays: use of censored data analysis (2003)

Probit regression analysis is frequently used to study the relation between the concentration of an analyte in a sample and the probability that the assay used yields a positive test result. For these analyses only the qualitative classification 'positive' or 'negative' is used, whereas, particularly in the case where the assay is quantitative in nature, the results contain more information. In the current paper, we propose an alternative method, in which the negative test results are treated as being (left) censored. As such, more efficient use is made of the information in the data. The procedures are illustrated using two generations of NucliSens assays (BioMérieux), which are designed to quantify the viral load of HIV-1 in blood samples. Computer simulations are used to illustrate some properties of the estimated parameters.
Generation of a homogeneous plasma and wide ion beams in a penning system with a nonequipotential cathode (2004)

A study is made of the possibility of controlling the spatial distribution of the degree of ionization in a modified Penning cell with a cathode divided into several sections that are at different potentials. It is shown that an almost uniform plasma can be produced when applying an optimal potential of the control electrode. This enables the generation of wide ion beams in this system. An ion extraction efficiency of several tens of percent is achieved, which is substantially higher than in conventional ion sources.
Blind Estimation of Effective Downlink Channel Gains in Massive MIMO (2015)

We consider the massive MIMO downlink with time-division duplex (TDD) operation and conjugate beamforming transmission. To reliably decode the desired signals, the users need to know the effective channel gain. In this paper, we propose a blind channel estimation method which can be applied at the users and which does not require any downlink pilots. We show that our proposed scheme can substantially outperform the case where each user has only statistical channel knowledge, and that the difference in performance is particularly large in certain types of channel, most notably keyhole channels. Compared to schemes that rely on downlink pilots, our proposed scheme yields more accurate channel estimates for a wide range of signal-to-noise ratios and avoid spending time-frequency resources on pilots.
Gamma decay of isoscalar and isovector giant resonances following heavy-ion inelastic scattering (1987)

Results from studies of gamma decay of giant resonances in /sup 208/Pb and /sup 90/Zr following inelastic excitation by 22 and 84 MeV/nucleon /sup 17/O ions are presented. Data on ground state decay of isoscalar giant quadrupole and isovector giant dipole resonances are presented and compared with calculations. Decays from resonances to low lying excited states are also discussed. Preliminary results from an attempt to isolate the isovector quadrupole resonance in /sup 208/Pb using its gamma decay are presented.
Sliding mode observer based position self-sensing control of a direct-drive PMSG wind turbine system fed by NPC converters (2013)

Information of rotor position and speed plays an crucial role in variable-speed wind energy conversion systems. Traditional sensors based position detection methods not only increase hardware complexity and system cost, but also face severe challenges on reliability caused by the disturbances from the varying weather and harsh operating conditions in wind energy generation sites. Thus, with the aim of eliminating position sensors and developing a reliable position self-sensing technique, this paper proposes a position self-sensing control method based on sliding mode observer for a 2 MW permanent magnet synchronous generator (PMSG) wind turbine system. In addition, a three-level neutral-point-clamped (NPC) back-to-back converter with space vector pulse width modulation (SVPWM) is developed for the full-scale power conversion, which has lower voltage stress on the switching devices and less harmonic distortion in the output voltage compared with those in traditional two-level power converters. Simulation analysis is carried out to verify the effectiveness of the proposed self-sensing method and the three-level SVPWM based back-to-back NPC converter. The simulation results soundly justified the feasibility of the proposed control scheme and power conversion strategy.

[The role of flow cytometry in the study of physiopathology of neutrophilic granulocytes]. (1995)

Flow cytometry represents an interesting methodological approach to human neutrophil function assessment and to the study of neutrophil biology. Several aspects of neutrophil activation can be evaluated by means of such technology: phagocytosis, respiratory burst, surface markers, modifications in intracellular pH, actin polymerization, membrane potential, aggregation. Neutrophil flow cytometric evaluation is suitable for whole blood evaluation and has been shown to be very specific and sensitive. In particular, whole blood methods have been developed in order to investigate phagocytosis, hydrogen peroxide production, and surface markers expression (integrins, receptors for the Fc fragment of IgG, selectins, etc.). Other aspects of neutrophil activation have to be investigated by using purified neutrophils.
Studying the propagation of light in strongly scattering media using terahertz pulses (2002)

We describe a new class of experiments involving applications of terahertz radiation to problems in biomedical imaging and diagnosis. These involve scale model measurements, in which information can be gained about pulse propagation in scattering media. Because of the scale-invariance of Maxwell's equations, these experiments can provide insight for researchers working on similar problems at shorter wavelengths. As a first demonstration, we measure the propagation constants for pulses in a dense collection of spherical scatterers, and compare to the predictions of the quasi-crystalline approximation. Even though the fractional volume in our measurements exceeds the limit of validity of this model, we find that it still predicts certain features of the propagation with reasonable accuracy.
Burden of <scp>HIV</scp> and hepatitis C co‐infection: the changing epidemiology of hepatitis C in <scp>HIV</scp> ‐infected patients in France (2014)

The decreasing prevalence and the change in patients profile in HIV-HCV co-infection underline the importance of continuing efforts to educate physicians and patients. This should increase the benefit of viral risk reduction policies and increase the access of co-infected patients to HCV treatment.
Spectrum and frequencies of mutations inMSH2 andMLH1 identified in 1,721 German families suspected of hereditary nonpolyposis colorectal cancer (2005)

Mutations in DNA MMR genes, mainly MSH2 and MLH1, account for the majority of HNPCC, an autosomal dominant predisposition to colorectal cancer and other malignancies. The evaluation of many questions regarding HNPCC requires clinically and genetically well-characterized HNPCC patient cohorts of reasonable size. One main focus of this multicenter study is the evaluation of the mutation spectrum and mutation frequencies in a large HNPCC cohort in Germany; 1,721 unrelated patients, mainly of German descent, who met the Bethesda criteria were included in the study. In tumor samples of 1,377 patients, microsatellite analysis was successfully performed and the results were applied to select patients eligible for mutation analysis. In the patients meeting the strict Amsterdam criteria (AC) for HNPCC, 72% of the tumors exhibited high microsatellite instability (MSI-H) while only 37% of the tumors from patients fulfilling the less stringent criteria showed MSI-H; 454 index patients (406 MSI-H and 48 meeting the AC of whom no tumor samples were available) were screened for small mutations. In 134 index patients, a pathogenic MSH2 mutation, and in 118 patients, a pathogenic MLH1 mutation was identified (overall detection rate for pathogenic mutations 56%). One hundred sixty distinct mutations were detected, of which 86 are novel mutations. Noteworthy is that 2 mutations were over-represented in our patient series: MSH2,c.942+3A>T and MLH1,c.1489_1490insC, which account for 11% and 18% of the MSH2 and MLH1 mutations, respectively. A subset of 238 patients was screened for large genomic deletions. In 24 (10%) patients, a deletion was found. In 72 patients, only unspecified variants were found. Our findings demonstrate that preselection by microsatellite analysis substantially raises mutation detection rates in patients not meeting the AC. As a mutation detection strategy for German HNPCC patients, we recommend to start with screening for large genomic deletions and to continue by screening for common mutations in exon 5 of MSH2 and exon 13 of MLH1 before searching for small mutations in the remaining exons.

Parameters Influencing the Liposome-Mediated Insertion of Fluorescein Diacetate into Plant Protoplasts (1981)

Maximum uptake of liposome-encapsulated fluorescein diacetate by Daucus carota protoplasts was observed when 6 x 10(6) protoplasts per milliliter were incubated with 2.4 x 10(7) liposomes per milliliter for 1 hour. In the case of Nicotiana glutinosa protoplasts, optimum ratio of protoplasts to liposomes was 1:10, where 2.3 x 10(5) protoplasts per milliliter were provided. Neutral and positive liposomes were found to be efficient vehicles to transfer their contents into plant protoplasts. When protoplasts treated with liposomes were cultured in a synthetic medium for 1 week, 20% resumed cell divisions.

Radio-On-Demand Sensor and Actuator Networks (ROD-SAN): System Design and Field Trial (2014)

Wireless sensor and actuator networks (WSANs) are required to achieve both energy-efficiency and low-latency in order to prolong the network lifetime while being able to quickly respond to intermittently-transmitted control commands. These two requirements are in general in a relationship of trade-off when each node operates with well-known duty-cycling modes: nodes need to make their radio interfaces (IFs) frequently active in order to promptly detect the communication requests from the other nodes. One approach to break this inherent trade-off, which has been actively studied in recent literature, is the introduction of wake-up receiver that is installed into each node and used only for detecting the communication requests. The radio IF in each node is woken up only when needed through a wake-up message received by the wake-up receiver. While the effectiveness of this type of on-demand WSANs has been shown in several studies by theoretical analysis and computer simulations, its implementation and large-scale experimental investigations are missing. Therefore, in this paper, we first design and implement radio-on-demand sensor and actuator networks (ROD-SAN) including all protocols to realize on-demand WSANs, from the lowest layer of wake-up signaling to the application layer offering the functionalities of information monitoring and networked control. Then, we show experimental results obtained through our field trial in which 20 nodes are deployed in an outdoor area with the scale of 450m X 200m. The numerical results provide us with practical insights on the effectiveness as well as limitations of on-demand WSANs.
Aspiration of the asymptomatic metatarsophalangeal joint in gout patients and hyperuricemic controls (1982)

Asymptomatic metatarsophalangeal joints were aspirated in a group of patients with gout, in 2 control groups with hyperuricemia, and in 1 normouricemic control group. Extracellular urate crystals were present in 70% of gout patients, in 1 of 19 patients with asymptomatic hyperuricemia, and in 2 of 9 patients with renal failure and hyperuricemia but no history of joint disease. Crystals were not found in the 10 normouricemic patients who had other types of arthritis. The presence of crystals in the subjects with gout was not correlated with a history of podagra, duration of gout, presence of tophi, or degree of control of hyperuricemia. Though crystals were found on rare occasions in joint fluid of asymptomatic hyperuricemic subjects, the presence of these crystals in asymptomatic joints was more common in subjects with gout.
Malignancy and Acute Pulmonary Embolism (2013)

Among subjects who present with acute PE, those with a malignancy had different clinical characteristics and predictors of mortality when compared with the cohort of subjects with no known malignancy. A computed tomography-derived right to left ventricular diameter ratio predicts 30-day all-cause mortality only for those subjects who do not have a malignancy.
Performance of super-resolution enhancement for LADAR camera data (2008)

Laser detection and ranging (LADAR) camera systems are increasingly used in robotics applications for autonomous navigation and obstacle avoidance. Their compact size, high frame rate, wide field-of-view, and low cost are key advantages over traditional scanning LADAR devices. However, these benefits are achieved at the cost of spatial resolution. Therefore super-resolution image reconstruction technology can be applied to improve the resolution of LADAR camera data. Previous work by Rosenbush et al. applied the super-resolution algorithm of Vandewalle et al. to LADAR camera data, and observed quantitative improvement in image quality in terms of number of edges detected. This study uses the super-resolution algorithm of Young et al. to enhance the resolution of range data acquired from a commercial available LADAR camera. This work applies a preprocessing stage that increases the accuracy of sub-pixel shift estimation for improved registration of multiple LADAR camera frames and uses the triangle orientation discrimination methodology for a subjective evaluation. The objective is to measure the improvement in probabilities of target discrimination at various ranges achieved by super-resolution enhancement of LADAR camera data.
Hilusdrüsenbeteiligung bei Lues II (1950)

Es wird ein Fall von Hilusdrüsenschwellung bei Lues II mitgeteilt, der längere Zeit als Hilusdrüsentuberkulose angesehen worden war. Differentialdiagnostisch werden Hilusdrüsentuberkulose, Morbus Boeck, Lymphogranulomatose und andere lymphatische Systemerkrankungen ausgeschlossen. Die Diagnose luetische Hilusdrüsenschwellung wird vor allem durch den Erfolg der antiluetischen Behandlung gestützt. Es wird hervorgehoben, daß Hilusdrüsenschwellungen bei Lues II nur unter besonderen Bedingungen röntgenologisch sichtbar werden. Als derartige Vorbedingungen wird vor allem das gleichzeitige Bestehen einer luetischen Tracheo-Bronchitis angesehen.
Measurements of photo-oxidation products from the reaction of a series of alkyl-benzenes with hydroxyl radicals during EXACT using comprehensive gas chromatography (2003)

Abstract. Photo-oxidation products from the reaction of a series of alkyl-benzenes, (benzene, toluene, p-xylene and 1,3,5-trimethyl-benzene) with hydroxyl radicals in the presence of NOx have been investigated using comprehensive gas chromatography (GCxGC). A GCxGC system has been developed which utilises valve modulation and independent separations as a function of both volatility and polarity. A number of carbonyl-type compounds were identified during a series of reactions carried out at the European Photoreactor (EUPHORE), a large volume outdoor reaction chamber in Valencia, Spain. Experiments were carried as part of the EXACT project (Effects of the oXidation of Aromatic Compounds in the Troposphere). Two litre chamber air samples were cryo-focused, with a sampling frequency of 30 minutes, allowing the evolution of species to be followed over oxidation periods of 3-6 hours. To facilitate product identification, several carbonyl compounds, which were possible products of the photo-oxidation, were synthesised and used as reference standards. For toluene reactions, observed oxygenated intermediates found included the co-eluting pair a-angelicalactone/4-oxo-2-pentenal, maleic anhydride, citraconic anhydride, benzaldehyde and p-methyl benzoquinone. In the p-xylene experiment, the products identified were E/Z-hex-3-en-2,5-dione and citraconic anhydride. For 1,3,5-TMB reactions, the products identified were 3,5-dimethylbenzaldehyde, 3,5-dimethyl-3H-furan-2-one and 3-methyl-5-methylene-5H-furan-2-one. Preliminary quantification was carried out on identified compounds using liquid standards. Comparison of FTIR and GCxGC for the measurement of the parent aromatics generally showed good agreement. Comparison of the concentrations observed by GCxGC to concentration-time profiles simulated using the Master Chemical Mechanism, MCMv3, demonstrates that this mechanism significantly over-predicts the concentrations of many product compounds and highlights the uncertainties which exist in our understanding of the atmospheric oxidation of aromatics.
Testing for Plant-parasitic Nematodes that Feed on Corn in Iowa 2000-2010 (2011)

The Iowa State University Plant and Insect Diagnostic Clinic analyzes soil and root samples for plant-parasitic nematodes. The results of samples associated with corn that were submitted from 2000 through 2010 were summarized. One or more genera of plant-parasitic nematodes were found in 92% of the samples. Spiral nematode and root-lesion nematode were most commonly found. Other nematodes recovered were dagger, lance, needle, pin, ring, and stunt nematodes. Nematodes recovered at damaging population densities were dagger, needle, ring, and spiral nematodes. An average of 15 samples were submitted per year from 2000 to 2004. Sample numbers increased nearly threefold since 2005, but overall sample numbers were low every year from 2000 through 2010. Samples were received from 53 of the 99 Iowa counties, and most samples were received in June and July, which is the recommended sampling time. Nematodes that have been associated with corn in Iowa in the past that were not recovered from the samples were sheath, sting, and stubby-root nematodes. The methods used to extract the nematodes from soil and roots and how the samples were handled during collection and processing may have affected the species and population densities recovered. Much more frequent and widespread sampling is needed in Iowa for plant-parasitic nematodes that feed on corn. Accepted for publication 28 October 2011. Published 5 December 2011.
