EFFICIENCY ENHANCEMENTS THROUGH THE USE OF MAGNETIC FIELD GRADIENT IN ORIENTATION MAGNETIC SEPARATION FOR THE REMOVAL OF POLLUTANTS BY MAGNETOTACTIC BACTERIA (2002)

Orientation magnetic separation (OMS) represents a simple method that permits motile, field-susceptible magnetotactic bacteria (MTB) to be separated from water. Such an approach can be used to decontaminate polluted water through uptake of contaminants by the bacteria and their subsequent removal by the application of magnetic fields. In OMS, a separation channel through which an MTB culture is flowing is subjected to a magnetic field perpendicular to the flow direction. The bacteria “sense” the magnetic field, orientating themselves parallel to the field lines and then swim to the channel sides where they accumulate. The fluid flow through such a standard separation channel has been shown to cause dislodgement of accumulated bacteria. To reduce this effect, a new approach has been developed utilizing magnetic gradients to retain the bacteria at the walls of the separator. A study comparing the operation of a standard channel separator with three new designs containing nickel wire matrices has been carried out. The resultant separation efficiencies and the effect on separation of varying both the flow rate and the applied magnetic field are described. The new separators enhance the separation efficiency by up to 300% over the standard separator.
Biosensor based on an oxygen reducing bilirubin oxidase electrode (2009)

An oxygen reducing electrode made of bilirubin oxidase and multi-walled carbon nanotubes (BOD-MWCNT-Au electrode) is coupled to enzymes catalysing oxygen-consuming reactions such as glucose oxidase (GOD) to result in a membrane-free bienzyme electrode.The feasibility of such a molecularly assembled system stabilized by covalent linkage has been demonstrated.The electrochemical characterisation of the bienzyme electrode reveals sensitivity to the enzyme substrate.The results indicate that the BOD-electrode provides a suitable platform for sensing analytes for which oxidases of high activity are available.

Effects of phytohemagglutinin on humoral antibody response, delayed hypersensitivity, and homograft rejection. (1970)

Phytohemagglutinin (PHA), a mucoprotein derived from the red kidney bean, Phaseolus vulgaris, has erythroagglutinating and leukoagglutinating properties and stimulates the small lymphocytes of the peripheral blood to transform into large blast cells.4, 5, 16, 18 When administered parenterally, it can suppress the immune response in animals, if treatment is started several days before the antigenic stimulation.7, 8, 10, 12, 15, 18, 19

To our knowledge 6 studies have been reported concerning the effect of PHA on the survival of skin or renal homografts, with conflicting results.2, 3, 6, 13, 14, 17 Calne and associates2 and Casciani and Cortesini3 treated canine recipients of renal allografts solely with PHA and found a slight immunosuppressive activity; the effect was additive to that of azathioprine if the 2 agents were given together. Two of 4 publications concerned with skin grafts in rodents and rabbits reported no detectable effect of PHA,6,13 but the other 2 claimed slight prolongation of skin viability.15,17

In our laboratory the immunosuppressive qualities of a particular batch of PHA were evaluated by the ability of this agent to blunt humoral antibody formation in rabbits, to suppress the development of delayed hypersensitivity reactions in guinea pigs, and to mitigate the rejection of renal homografts in dogs. In addition the effect of red cell absorption on the biologic activity of PHA was assessed.
Reflexiones sobre la política prefigurativa (2014)

?Como concebir la lucha contra las opresiones y el sistema actual? Los defensores de la llamada «politica prefigurativa» plantean que es necesario «anticipar» la nueva sociedad en nuestras practicas actuales. Sin embargo, no existe una correlacion uno a uno entre los metodos, la estrategia y las tacticas de un movimiento de oposicion y aquellas del sistema socioeconomico y politico que emerge de el y que debe garantizar nuevas formas de democracia, asi como una reorganizacion radical del poder y, por ende, de la riqueza. Por eso es necesario (re)pensar el problema del poder, el Estado y la economia sin desechar la politica estrategica y sin caer en formas utopicas de pensar el cambio social que a menudo postulan comunitarismos incompatibles con la emancipacion
The Magnetic Anisotropy Constant in the Case of Strong Anisotropy (1962)

A correct perturbational approach to the calculation of the magnetic anisotropy energy is presented. The theory is applicable even to the case of extreme anisotropy. The anisotropy energy is to be evaluated from the total (free) energy in a given direction of the magnetization vector. It is emphasized that one has to take into account, particularly in the higher order perturbation calculation, the presence of a thermo-dynamic magnetic field which fixes the magnetization vector in the given direction, because otherwise the magnetization vector deviates from the assumed direction, producing a false energy change. As an application the anisotropy energy in FeF 2 is calculated. The present theory yields a consistent explanation of both the magnitude and the temperature dependence of the observed anisotropy energy in FeF 2 .

Discriminator-Aided Optical Phase-Lock Loop Incorporating a Frequency Down-Conversion Module (2006)

A new discriminator-aided optical phase-lock loop (OPLL) incorporating a frequency down-conversion module to generate a low phase noise, highly frequency-stable, and frequency-tunable microwave signal is proposed and demonstrated. The inclusion of the frequency down-conversion module allows the use of lower frequency components in the control circuits with a reduced cost. In addition, the new design allows continuous frequency tuning of the generated microwave signal. The down-conversion concept is presented, along with a phase noise analysis detailing the contributions to the phase noise from the reference sources. An OPLL based on the proposed configuration is implemented. The phase noise performance, as well as the frequency stability is experimentally studied
Using phase characteristics of speech to distinguish /m/ and /n/ (2006)

A method is presented for extracting a useful phase signal from natural input speech. The phase signal is then processed to extract signatures for /m/ and /n/ based on the variance of the phase. An average signature is created for each of 8 speakers using three utterances of each /m/ and /n/. This average signature is then used to classify unknown input utterances. Classification accuracy averages 75%.
Cognitive Performance in Drug-naÏve First Episode Schizophrenia (FES) Patients (2015)

A majority of the studies on cognition in schizophrenia have been conducted in drug-treated patients. In healthy subjects, administration of antipsychotic medication has been found to have a negative impact on cognitive performance in domains such as speed of processing and attention. Antipsychotic drugs occupy the D2-dopamine receptor, a receptor subtype that has been related to cognitive function. Studies employing Positron Emission Tomography have shown that poor performance in several cognitive domains is associated to low D2-receptor binding. It is therefore crucial to examine cognition in drug-naïve patients with schizophrenia. In FES patients: To examine the profile of cognitive impairments in the absence of antipsychotic medication and compare with the cognitive profile of patients who are on antipsychotic medication. To study cognition in FES. The Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) battery was administered to 60 patients with early schizophrenia and 30 healthy controls, 50% of the patients were drug-naïve. This research is ongoing and a part of the Karolinska Schizophrenia Project (KaSP), a multidisciplinary research consortium that examines the pathophysiology of schizophrenia. Preliminary findings show that patients perform worse than healthy controls in all cognitive domains, with no significant differences between drug-naïve and medicated patients. Attention and Visual memory were the domains with the greatest impairments. The results are compared with our previous meta-analytic findings in drug-naïve patients. These preliminary findings confirm the existence of cognitive impairments at the early stage of schizophrenia in the absence of antipsychotic medication.
Multiplier blocks and complexity of IIRstructures (1994)

For discrete coefficient IIR filters, low sensitivity (e.g. wave) structures have been preferred to other (e.g. direct, cascade and parallel) structures due to their requirement for shorter wordlengths. Multiplier blocks, using redundancy between coefficients, can make these structures comparable or superior to wave filters in implementation complexity.
Autotuning Stencil Computations with Structural Ordinal Regression Learning (2017)

Stencil computations expose a large and complex space of equivalent implementations. These computations often rely on autotuning techniques, based on iterative compilation or machine learning (ML), to achieve high performance. Iterative compilation autotuning is a challenging and time-consuming task that may be unaffordable in many scenarios. Meanwhile, traditional ML autotuning approaches exploiting classification algorithms (such as neural networks and support vector machines) face difficulties in capturing all features of large search spaces. This paper proposes a new way of automatically tuning stencil computations based on structural learning. By organizing the training data in a set of partially-sorted samples (i.e., rankings), the problem is formulated as a ranking prediction model, which translates to an ordinal regression problem. Our approach can be coupled with an iterative compilation method or used as a standalone autotuner. We demonstrate its potential by comparing it with state-of-the-art iterative compilation methods on a set of nine stencil codes and by analyzing the quality of the obtained ranking in terms of Kendall rank correlation coefficients.

Advanced fault analysis in web service composition (2005)

Currently, fault management in Web Services orchestrating multiple suppliers relies on a local analysis, that does not span across individual services, thus limiting the effectiveness of recovery strategies. We propose to address this limitation by employing Model-Based Diagnosis to enhance fault analysis. In our approach, a Diagnostic Web Service is added to the set of Web Services providing the overall service, and acts as a supervisor of their execution, by identifying anomalies and explaining them in terms of faults to be repaired.

HETS: Heterogeneous Edge and Task Scheduling Algorithm for Heterogeneous Computing Systems (2015)

Widely used computing systems are heterogeneous in nature, comprising of interconnected resources which differ in computational capability of processing nodes and network bandwidth. Due to this diversity, an efficient heuristic is required to achieve high performance in heterogeneous computing system. In our proposed scheduling algorithm, Heterogeneous Edge and Task Scheduling (HETS), we schedule the communication between the tasks of application graph onto the network links of varying bandwidth, and schedule these tasks of different computation on the network processors after considering the computational capability of the available processors. In HETS, the prioritization is done by calculating the edge priority as well as the node priority. HETS algorithm selects the task after all its incoming edges are scheduled. The proposed algorithm minimizes the communication overhead of the application graph edges and obtains reduced schedule length in terms of the over allexecution time. Performance of the proposed algorithm is studied by varying parameters of the standard task graphs as well as on real world directed acyclic graphs (DAGs) application, such as Cybershake, Gaussian Elimination, and Montage. Extensive simulation results show the effectiveness of HETS algorithm interms of reduced makespan and improved Schedule Length Ratio(SLR) for the given tasks.
[Analysis of DNMT3a gene mutations in acute myelogenous leukemia]. (2011)

This study was purposed to investigate the mutational status of DNA methyltransferase (DNMT3a) gene and the clinical features of AML patients with DNMT3a mutations. Using PCR combined with directly sequencing, the somatic mutations of DNMT3a involving residue of amino acid 882 were detected in 77 AML patients. Furthermore, the clinical features of these patients were also studied. The results showed that the DNMT3a mutation were detected in 7 out of 59 patients with de novo AML (11.9%), which included 4 patients with DNMT3a R882C, 2 patients with DNMT3a R882H and 1 patient with DNMT3a Y874C. Morphology examination indicated that 2 patients were M(2), 1 patient was M(4) and 4 patients were M(5). Cytogenetic analysis revealed that karyotype in 5 out of 7 patients with DNMT3a mutation were normal. In total of 27 patients with normal karyotype 5 patients (22.7%) were found harboring DNMT3a mutation, while no DNMT3a mutation was found in 21 patients with abnormal karyotype. The mutation rate in patients with positive CEBPA was obviously higher than that in patients with negative CEBPA (p = 0.002). Immunophenotype analysis showed that 4 patients (4/7, 57.1%) with DNMT3a mutation expressed lymphoid antigens including CD4 or/and CD7. There were no statistical significance in age, gender, blast cells of bone marrow, white blood cell and platelet counts, hemoglobin level, ratio of CR, mutations of FLT3-ITD, NPM1 and c-kit between patients with DNMT3a mutation and patients with wild DNMT3a (p > 0.05). It is concluded that the DNMT3a mutations are more prevalent in AML patients with normal karyotype accompanying with positive NPM1 and/or CEBPA mutation, the role of DNMT3a mutation in AML prognosis needs to be further studied.
Beyond Slurry-Cast Supercapacitor Electrodes: PAN/MWNT Heteromat-Mediated Ultrahigh Capacitance Electrode Sheets (2017)

Supercapacitors (SCs) have garnered considerable attention as an appealing power source for forthcoming smart energy era. An ultimate challenge facing the SCs is the acquisition of higher energy density without impairing their other electrochemical properties. Herein, we demonstrate a new class of polyacrylonitrile (PAN)/multi-walled carbon tube (MWNT) heteromat-mediated ultrahigh capacitance electrode sheets as an unusual electrode architecture strategy to address the aforementioned issue. Vanadium pentoxide (V<sub>2</sub>O<sub>5</sub>) is chosen as a model electrode material to explore the feasibility of the suggested concept. The heteromat V<sub>2</sub>O<sub>5</sub> electrode sheets are produced through one-pot fabrication based on concurrent electrospraying (for V<sub>2</sub>O<sub>5</sub> precursor/MWNT) and electrospinning (for PAN nanofiber) followed by calcination, leading to compact packing of V<sub>2</sub>O<sub>5</sub> materials in intimate contact with MWNTs and PAN nanofibers. As a consequence, the heteromat V<sub>2</sub>O<sub>5</sub> electrode sheets offer three-dimensionally bicontinuous electron (arising from MWNT networks)/ion (from spatially reticulated interstitial voids to be filled with liquid electrolytes) conduction pathways, thereby facilitating redox reaction kinetics of V<sub>2</sub>O<sub>5</sub> materials. In addition, elimination of heavy metallic foil current collectors, in combination with the dense packing of V<sub>2</sub>O<sub>5</sub> materials, significantly increases (electrode sheet-based) specific capacitances far beyond those accessible with conventional slurry-cast electrodes.

Direct measurement of stresses in concrete structures (1982)

To evaluate the absolute stresses in concrete structures, a direct method by partial stress release has been developed. It consists of cutting a slot in the concrete, restoring the initial strain field with an ultra-fine flat jack and measuring the pressure. The method has been thoroughly examined from its theoretical, technological and metrological aspects. It is now operational with an error margin of 0,3 MPa for both compression and tension. Following a thorough study of the shrinkage stress distribution, it is now possible to separate the two components of the measured absolute stress: applied and residual. (Author)
Subsurface geometry interpretation by integrating continuous wavetet transform seismic attributes (2013)

Seismic interpretation is highly dependent of the seismic resolution. Sequence stratigraphy, fractures detection, faults interpretation and channels delineation can be improved by using better resolution seismic data. Considering spectral decomposition a way increase seismic traces details, we used complex continuous wavelet transform (CWT) ridges to create a higher resolution traces and the phase discontinuities to detect subtle seismic discontinuities. By integrating these seismic attributes we showed how to improve the understanding of subsurface geometry. The technique was applied to real data and confirmed the effectiveness of the proposed methodology.
Nucleation layer evolution in metal-organic chemical vapor deposition grown GaN (1996)

The structure and morphology of low growth temperature GaN nucleation layers have been studied using atomic force microscopy (AFM), reflection high energy electron diffraction (RHEED), and transmission electron microscopy (TEM). The nucleation layers were grown at 600 °C by atmospheric pressure metalorganic chemical vapor deposition (MOCVD) on c-plane sapphire. The layers consist of predominantly cubic GaN (c-GaN) with a high density of stacking faults and twins parallel to the film/substrate interface. The average grain size increases with increasing layer thickness and during the transition from low temperature (600 °C) to the high temperatures (1080 °C) necessary for the growth of device quality GaN. Upon heating to 1080 °C the nucleation layer partially converts to hexagonal GaN (h-GaN) while retaining a high stacking fault density. The mixed cubic-hexagonal character of the nucleation layer region is sustained after subsequent high-temperature GaN growth.
Effectiveness of Cone Emergence Traps for Detecting Phyllophaga vandinei Emergence over Time (2008)

Cone emergence cages are used to monitor populations of soil-borne insects, particularly beetles, during adult emergence. Because the cone emergence cage presumably denies access to adult beetles, including adult females, it is thought that a cone emergence cage left in place for longer than the lifecycle of the insect will have few or no beetles emerge in it. The authors tested the premise that a cone emergence cage left in place for 1 year or longer would no longer be useful as a tool to monitor the emergence of adult Phyllophaga vandinei Smyth. Our results indicate not only that cone emergence cages left in place for more than a year (P. vandinei is reported to be univoltine) are still effective at monitoring P. vandinei emergence, but often yield even more adult beetles than cone emergence cages that have been in place for a shorter time. It is not clear if this is a result of when the trap is placed or where the trap is placed. This also raises the question of whether the larvae of P. vandinei may take 1 or more years to complete development.
