<title>Optimal affine-invariant matching: performance characterization</title> (1992)

The geometric hashing scheme proposed by Lamdan and Wolfson can be very efficient in a model-based matching system, not only in terms of the computational complexity involved, but also in terms of the simplicity of the method. In a recent paper, we discussed errors that can occur with this method due to quantization, stability, symmetry, and noise problems. These errors make the original geometric hashing technique unsuitable for use on the factory floor. Beginning with an explicit noise model, which the original Lamdan and Wolfson technique lacks, we derived an optimal approach that overcomes these problems. We showed that the results obtained with the new algorithm are clearly better than the results from the original method. This paper addresses the performance characterization of the geometric hashing technique, more specifically the affine-invariant point matching, applied to the problem of recognizing and determining the pose of sheet metal parts. The experiments indicate that with a model having 10 to 14 points, with 2 points of the model undetected and 10 extraneous points detected, and with the model points perturbed by Gaussian noise of standard deviation 3 (0.58 of range), the average amount of computation required to obtain an answer is equivalent to trying 11 of the possible three-point bases. The misdetection rate, measured by the percentage of correct bases matches that fail to verify, is 0.9. The percentage of incorrect bases that successfully produced a match that did verify (false alarm rate) is 13. And, finally, 2 of the experiments failed to find a correct match and verify it. Results for experiments with real images are also presented.
Empirically Evaluating Regression Testing Techniques: Challenges, Solutions, and a Potential Way Forward (2011)

The published studies of regression testing methods often contain many of the hallmarks of high quality empirical research. Beyond features like clear descriptions of the methodology and the visualization and statistical analysis of the data sets, certain papers in this field also provide some of the artifacts used in and/or produced by the experiments. Yet, the limited industrial adoption of regression testing techniques is due in part to a lack of comprehensive empirical evaluations. Moreover, the regression testing community has not achieved a level of experimental reproducibility that would fully establish it as a science. After identifying the challenges associated with evaluating regression testing methods, this paper advocates a way forward involving a mutually beneficial increased sharing of the inputs, outputs, and procedures used in experiments.
Identification and characterization of a major tolerogenic T-cell epitope of type II collagen that suppresses arthritis in B10.RIII mice. (1995)

Tolerization of B10.RIII mice (H-2r) with intravenously injected type II collagen (CII) renders the animals resistant to induction of collagen-induced arthritis (CIA). In order to clarify H-2r-restricted T-cell responses that modulate CIA, we have analysed the T-cell proliferative response of B10.RIII mice against cyanogen bromide (CB) peptides of CII, and detected the strongest response to alpha 1(II)-CB10 (CII 552-897). A panel of chemically synthesized overlapping peptide homologues was used to deduce the minimum structure of this determinant which was found to be CII 610-618. A 15-residue synthetic peptide flanking this region, CII 607-621, was found to effectively suppress arthritis when administered as a tolerogen. Collectively, these data identify the structural component within alpha 1(II)-CB10 which is capable of inducing tolerance in B10.RIII mice. A similar approach to the treatment of autoimmune arthritis, involving the institution of self-tolerance, has potential applicability to human rheumatoid arthritis.
Understanding crystallization pathways leading to manganese oxide polymorph formation (2018)

Hydrothermal synthesis is challenging in metal oxide systems with diverse polymorphism, as reaction products are often sensitive to subtle variations in synthesis parameters. This sensitivity is rooted in the non-equilibrium nature of low-temperature crystallization, where competition between different metastable phases can lead to complex multistage crystallization pathways. Here, we propose an ab initio framework to predict how particle size and solution composition influence polymorph stability during nucleation and growth. We validate this framework using in situ X-ray scattering, by monitoring how the hydrothermal synthesis of MnO<sub>2</sub> proceeds through different crystallization pathways under varying solution potassium ion concentrations ([K<sup>+</sup>] = 0, 0.2, and 0.33 M). We find that our computed size-dependent phase diagrams qualitatively capture which metastable polymorphs appear, the order of their appearance, and their relative lifetimes. Our combined computational and experimental approach offers a rational and systematic paradigm for the aqueous synthesis of target metal oxides.
[Neo-bladder made from the rectum in surgical cure of uro-genital malformations (author's transl)]. (1976)

The authors give a critical account of the results of artificial bladder construction using the rectum in complex genito-urinary malformations, such as, extrophic bladder, failure of correction of epispadias, and discuss 12 personal cases of which 6 out of 10 had been followed up for between 10 and 15 years. One important recommendation: in adults where the shincter system is normal, according to our experience, there is little trouble with urinary or fecal incontinence. In children, it is still necessary to develop a procedure which might permit one to express, numerically, the conclusions of the electrical examination and the volume above which resistance begins to break down. In small boys, after formation of the new bladder, one should attempt to restore micturition by the natural route, by reconstruction of the neck of the bladder, ileoplasty and reimplantation of the ureters in situ.
Activity, Safety, and Immunological Effects of Hydroxyurea Added to Didanosine in Antiretroviral-Naive and Experienced HIV Type 1-Infected Subjects: A Randomized, Placebo-Controlled Trial, ACTG 307 (2004)

We performed a 24-week, placebo-controlled, comparative trial of hydroxyurea (HU) monotherapy, didanosine(ddI) monotherapy, and the combination of ddI plus HU administered as 1000 mg qd or 1500 mg qd in antiretroviral-naive and experienced subjects with CD4+ lymphocyte counts of 200-700 cells/mm3. Enrollment included 134 subjects. HU enhanced the antiviral activity of ddI by 1.0 log10 copies/ml after 8 weeks of therapy, with sustained responses over 24 weeks. HU alone over 4 weeks had no effect. Lamivudine resistance had little impact on antiretroviral activity when examined across treatment arms. Increases in absolute CD4+ T cell counts, but not CD4+ T cell percentages, were less in subjects who received HU compared to ddI monotherapy, and lymphoproliferative responses to antigenic and mitogenic stimuli were not altered. Subjects who received HU 1500 mg were more likely to experience dose-limiting hematological toxicities compared to those who received 1000 mg, without any additional antiviral benefit. HU may continue to have a role as a component of HIV therapy.
Exchange red blood cell pheresis in a pediatric patient with severe complications of sickle cell anemia (1981)

Exchange transfusion is a well‐established procedure for the treatment of severe complications of sickle cell anemia. However, large‐volume exchange is a difficult, time‐consuming technique, and therefore rarely used. Exchange red blood cell pheresis, using automated equipment, can accomplish red blood cell exchange more rapidly and efficiently, and can be easily performed by a skilled team of nursing personnel. The recent introduction of a pediatric centrifuge bowl allows this technique to be applied to pediatric patients. This procedure was used in a 13‐year‐old male with sickle cell anemia, who presented with bilateral pulmonary infiltrates, respiratory distress, and hypoxemia, unresponsive to antibiotics and other means of conservative therapy. A one and one‐half volume red blood cell exchange reduced the hemoglobin S concentration to 13 per cent. The patient experienced dramatic improvement within 24 hours, progressing to complete recovery within a few days.
2P1-A08 Development of a kinematical and electrophysiological analysis system for the measurement of tendon reflexes (2006)

Objective: To develop a compound system with a synchronized kinematical and electrophysiological method for measuring tendon reflex responses and to evaluate normal reflexes of a volunteer. Design: With the subject relaxed, a hand-held instrumented hammer was used to tap the patellar tendon and record the tapping force, while the reflex linear speed at the ankle and the quadriceps electromyography (EMG) were recorded as measures of the reflex response. The subject is a healthy volunteer exhibiting normal reflexes. Main Outcome Measures: The peak tapping force, peak reflex speed, peak-to-peak T-reflex amplitude, and their dynamic relationship with certain time parameters. Results: The time parameters provide more repeatable measures. At increasing peak to peak T-reflex amplitude, peak reflex speed increased. The output measures indicate their potential values in clinical applications. Conclusions: With appropriate simplifications, the method may be used in clinical practice to quantify more precisely the tendon reflex examination than is currently feasible with standard clinical tests.

Haematology of the turbot, Psetta maxima (L.): ultrastructural, cytochemical and morphological properties of peripheral blood leucocytes (2001)

Optimum procedures for fish handling and sample processing for use when employing haematological parameters as health indicators in turbot, Psetta maxima (L.), have been established. We found thrombocytes to be the most abundant blood cell, representing approximately 52% of circulating leucocytes (lymphocytes, 40.8%; granulocytes, 5.6%; monocytes, 1.6%; total number of leucocytes=1.3 × 105 ml−1; packed cell volume=22.7%). The light- and electron-microscopical characteristics of these cell types are described, together with their cytochemical properties using Sudan Black B, Periodic Acid Schiff, Non-specific Esterase, and Acid and Alkaline Phosphatase. Turbot thrombocytes showed a high degree of shape alterations when observed in live preparations using phase contrast microscopy, while ultrastructural observations following the in vitro uptake of carbon particles supported an active process of phagocytosis by the thrombocytes, rather than passive entrapment. The lymphocytes of turbot are structurally similar to mammalian lymphocytes with the highest nuclear:cytoplasmic ratio of all the leucocytes observed. Small lymphocytes predominated, large lymphocytes forming less than 1% of the total white blood cell population. The most frequent granulocyte type was a neutrophil-like cell with an eccentric nucleus, only rarely seen in segmented form. In vitro uptake of carbon particles by granulocytes was not observed under the conditions of the experiment, although turbot granulocytes are capable of phagocytosis under different circumstances. These are discussed, along with other physiological and technical factors which can influence the blood parameter findings in fish.
Low-dose dexmedetomidine facilitates the carotid body response to low oxygen tension in vitro via α2-adrenergic receptor activation in rabbits (2012)

Dexmedetomidine does not depress the activity of the carotid body under high oxygen tension or the response to low oxygen tension, whereas 0.1 nmol l dexmedetomidine facilitates this response via α2-adrenergic receptor activation.
Modélisation grands signaux de convertisseurs à résonance série (1992)

La modélisation des convertisseurs statiques à résonance est complexe car le circuit, de par sa topologie périodiquement modifiée au cours du fonctionnement, a un comportement global non linéaire. Le modèle proposé se base sur un développement harmonique à l'ordre supérieur au premier ordre, facile à mettre en œuvre et tenant compte du facteur d'amortissement du circuit oscillant. Ce modèle permet en outre l'étude dynamique du circuit. La méthode un fois introduite est appliquée sur un exemple de convertisseur à résonance série. A partir des résultats obtenus, le modèle est étendu à toute une classe de convertisseurs à résonance pour aboutir à un modèle général unique. Il est, par la suite, procédé à une validation expérimentale ainsi qu'à une comparaison avec le modèle classique du générateur de courant moyen équivalent. Cet article se termine par une application du modèle à l'analyse de la stabilité de ce type de convertisseur.

Studies of the inhibition of autooxidation of polypropylene with 4,4′-bis(2,6-di-<i>tert</i>-butylphenol) (1995)

The kinetics of 4,4′-bis(2,6-di-tert-butylphenol) (BP) consumption in the oxidation of polypropylene (PP) at 130 °C in air has been studied. It is shown that 3,3′,5,5′-tetra-tert-butyl-4,4′-diphenoquinone (DPQ) is the main product of conversion of the starting BP. An effect of synergism has been revealed on studying stabilization of PP with BP–DPQ mixtures. The antioxidative activity of BP was compared with that of some other stabilizers. Keywords: polypropylene oxidation, antioxidative activity, 4,4′-bis(2,6-di-tert-butylphenol), 3,3′,5,5′-tetra-tert-butyl-4,4′-diphenoquinone.

Selective Elevation of Monocyte Chemotactic Protein-1 in the Cerebrospinal Fluid of AIDS Patients with Cytomegalovirus Encephalitis (1996)

The CC chemokine monocyte chemotactic protein-1 (MCP-1) was markedly elevated in the cerebrospinal fluid (CSF) of human immunodeficiency virus (HIV)-infected patients with cytomegalovirus (CMV) encephalitis. The MCP-1 CSF levels in CMV encephalitis were markedly higher than those in the CSF of HIV-infected patients with or without unrelated neurologic diseases, including progressive multifocal leukoencephalopathy, cryptococcal meningitis, toxoplasmic encephalitis, and primary lymphoma. Interleukin-8, RANTES, macrophage inflammatory protein (MIP)-1 alpha, and MIP-1 beta were not substantially increased in the CSF of CMV encephalitis patients. High levels of MCP-1 may underlie monocyte recruitment and tissue damage in CMV encephalitis and may represent a rapid and useful tool in the diagnostic armamentarium for neurologic disorders associated with HIV infection.

1.3 µm emission from InAs/GaAs quantum dots (2006)

Abstract We report here the results of our photoluminescence study of a series of single quantum dot layer structures containing In x Ga 1–x As strain reducing layers with different In concentration (from 0% to 29%), prepared by low pressure metal organic vapour phase epitaxy. These structures display a strong red shift of photoluminescence maxima from 1.25 μm to 1.45 μm at 300 K with increased In content in the ternary layer. The origin of the observed transitions has been explained using magnetophotoluminescence measurements and photoluminescence measurements for different pumping intensities at low temperature. Optical transition energies were calculated using a simple single‐band effective mass model with energy‐dependent effective mass. Comparing the calculated and measured energies, we can determine the thickness of the wetting layer and the sizes of the dots. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Electronic coupling in MgxZn1−xO/ZnO double quantum wells (2009)

The electronic coupling in ZnO/MgZnO double-quantum-well (DQW) structures grown with pulsed-laser deposition is investigated. The two ZnO quantum wells, separated by a thin MgxZn1−xO barrier (x≈0.14–0.16), have either an equal (SDQW) or a different thickness (ADQW). The authors report here a detailed investigation by spatially and spectrally resolved cathodoluminescence (CL). For the SDQW structures, the shift of the transition energy of the free exciton at room temperature to lower energies due to electron coupling, with decreasing barrier width, is in good agreement with effective mass theory. For a barrier thickness LB≤5 nm, the ADQWs show an additional recombination peak located spectrally between the luminescence maxima of the corresponding single quantum wells. It is tentatively attributed to a spatially indirect excitonic transition involving the electron subband of the narrow well and the heavy hole subband of the wide well. An extension of the barrier thickness to 300 nm allows an estimation of the exciton diffusion length via lateral CL scans. In the case here the diffusion length in the MgZnO barrier is about 135 nm at 10 K and below 75 nm at room temperature.
A new strategy for the early detection of colorectal cancer recurrence. (2012)

416 Background: Several biological markers have been tested for colorectal cancer (CRC) including CEA; however, they are of limited use for recurrence diagnosis due to low sensitivity. Almost 50% of CRC cases experience recurrence and more than 50% of them have low values not detectable by CEA. Therefore, an effective marker for detection of recurrence will vastly increase the quality of life and survival rate. Onko-Sure is an FDA-cleared blood test that is used for the monitoring of treatment/recurrence of CRC. This ELISA assay measures the accumulation of Fibrin/Fibrinogen Degradation products in the serum using an antibody against the DR-70. The goal of this study was to determine whether the combined usage of DR-70 and CEA will improve the sensitivity for detecting recurrences. Methods: A total of 75 serum samples were retrospectively recruited through a serum bank in two arms including the confirmed healthy control (n=39) and biopsy-confirmed recurrent CRC (n=36) groups. For each patient, the serum sample was tested for DR-70 and CEA concentrations. Results: The results showed sensitivity of 75% and specificity of 58.97% for DR-70 and CEA combined. The cut points were calculated as 1.3ug/ml for DR-70, and 3 or 5ng/ml for CEA for non-smokers and smokers; respectively. For the combined analysis, if either CEA or DR-70 was positive, the test was considered positive and if both tests were negative, the result was considered negative. The sensitivity for the combined test was much better than that of each of the markers alone (35% higher than that of CEA). Conclusions: The combined usage of DR-70 and CEA in monitoring of CRC recurrence showed a significant clinical advantage in terms of sensitivity over each marker alone. Improvement in detection of recurrence has important implications to patient treatment options and prognosis. Should an IVD increase early detection of CRC recurrence when used adjunctively with other available diagnostic markers, the annual deaths due to CRC recurrence could be reduced due to the increase in early detection and the survival rate of those early detections.
Complexation of Crystal Violet, Pyronine B, and Rhodamine B by Linked ß-Cyclodextrin Trimers (2013)

The host-guest complexation by ß-cyclodextrin (ßCD), 1,3,5-N,N,N-tris-(6A-deoxy-6A-ß-cyclodextrin)-benzene (ßCD3bz), and 1,3,5-N,N,N-tris(6A-(2-aminoethyl)amino-6A-deoxy-6A-ß-cyclodextrin)-benzene (ßCDen3bz) of cationic crystal violet (CV+) and pyronine B (PB+) and zwitterionic rhodamine B (RB) in aqueous phosphate buffer at pH 7.0 and I = 0.10 mol dm–3 has been studied by UV-Vis and 1H NMR spectroscopy. The complexation constants 10–3K1 (298.2 K) are 4.68, 86.3, and 7.08 dm3 mol–1 for the 1 : 1 host-guest complexes: ßCD.CV+, ßCD3bz.CV+, ßCDen3bz.CV+, respectively, and those for the analogous PB+ and RB complexes have also been determined. The associated ?Ho and T?So for all nine complexes coincide with an entropy-enthalpy compensation plot for the formation of a wide range of ßCD and modified ßCD host-guest complexes reported in the literature. Crystal violet also forms (ßCD)2.CV+, (ßCD3bz)2.CV+ and (ßCDen3bz)2.CV+ complexes characterised by 10–2K2 (298.2 K) = 2.14, 4.57, and 3.86 dm3 mol–1 and analogous (ßCD)2.PB+, (ßCDen3bz)2.PB+ and (ßCDen3bz)2.RB complexes also form, but the (ßCD3bz)2.PB+, (ßCD)2.RB, and (ßCD3bz)2.RB complexes were not detected. The effects of the structures of the hosts and guests on the complexation processes are discussed.

The future of nanosized radiation enhancers (2015)

Radiotherapy has a universal and predictable mode of action, that is, a physical mode of action consisting of the deposit of a dose of energy in tissues. Tumour cell damage is proportional to the energy dose. However, the main limitation of radiotherapy is the lack of spatial control of the deposition of energy, that is, it penetrates the healthy tissues, damages them and renders unfeasible delivery of an efficient energy dose when tumours are close to important anatomical structures. True nanosized radiation enhancers may represent a disruptive approach to broaden the therapeutic window of radiation therapy. They offer the possibility of entering tumour cells and depositing high amounts of energy in the tumour only when exposed to ionizing radiations (on/off activity). They may unlock the potential of radiation therapy by rendering the introduction of a greater energy dose, exactly within the tumour structure without passing through surrounding tissues feasible. Several nanosized radiation enhancers have been studied in in vitro and in vivo models with positive results. One agent has received the authorization to conduct clinical trials for human use. Opportunities to improve outcomes for patients receiving radiotherapy, to create new standards of care and to offer solutions to new patient populations are looked over here.
