Micro-pressing of rapeseed (Brassica napusL.) andArabidopsis thalianaseeds for evaluation of the oil extractability (2010)

Pressing is a crucial step in the crushing process of rapeseed seeds, regarding its major effect on the oil extraction yield, the energy consumption and the quality of the meal. In order to study and model in a rigorous way the behaviour of rapeseed seeds, and the oil extraction during pressing, the potential of a micro-pressing technique using a instrumented micro press adapted to quantities of seeds as low as 10 g for rapeseed and 3 g for Arabidopsis thaliana was examined and discussed. Using a phenomenological model, data from the pressing process and the material behaviour (compressibility modules) were obtained with a good precision, highlighting small differences between samples. The well-known positive effect of the temperature on the oil extraction yield was confirmed with A. thaliana. Micro-pressing of ground and cooked rapeseed seeds did not lead to the results usually reported in the literature for continuous pressing. The results strongly suggest that the performance of the static micro-pressing is related to the macro-and micro-structure of seeds and is less sensitive to the moisture than continuous pressing. Further experiments are needed to confirm that the micro-pressing could be an effective tool for predicting the extractability of oil and therefore, contribute to plant breeding programmes in the future.
Analysis of microtubule-associated protein tau glycation in paired helical filaments. (1994)

Alzheimer's disease is typified by the characteristic histopathological lesions of neurofibrillar plaques and tangles. The latter are composed of paired helical filaments (PHFs), the major components of which are modified forms of the microtubule-associated protein tau. The exact nature of these modifications remains unknown, although the presence of hyperphosphorylated tau in PHFs argues strongly that phosphorylation is one of the modifications that result in the polymerization of tau into PHFs. However, hyperphosphorylation alone is insufficient to explain the formation of PHFs. In an attempt to characterize other post-translational modifications of PHF-tau, we have analyzed its glycation. A fraction of PHF-tau seems to be glycated in vivo, whereas soluble tau from either Alzheimer's disease or non-demented human brain is not glycated at all. Purified tau from bovine brain can be efficiently glycated in vitro. Tau glycation is accompanied by a decrease in the tau binding to tubulin. These results support the view that glycation may be one of the modifications hampering the binding of tau to tubulin in Alzheimer's disease, thus facilitating tau aggregation into PHFs.
Magnetically Tunable 28 GHz Array Antenna Using BaM/PDMS Composite (2021)

In this work, we present a magnetically tunable 2 x 2 array antenna operating at 28 GHz using a screen-printed self-biased magnetic/polymer composite that consists of 70 wt&#x0025; barium hexaferrite (BaM) and 30 wt&#x0025; polydimethylsiloxane (PDMS). Unlike high temperature processing for traditional hexaferrite annealing <tex>$(&#x003E; 800^{\circ}\mathrm{C})$</tex>, this work demonstrates a low-temperature process flow at 7 <tex>$0\ ^{\circ}\mathrm{C}$</tex> making it compatible for organic/PCB board integration and packaging. By applying an external magnetic field of <tex>$\pm 240\ \mathbf{mT}$</tex>, a tunability range of 0.3 GHz is achieved. Also, the array antenna structure is simulated using High Frequency Structure Simulator (HFSS). The total area of the fabricated device is 0.84 cm<sup>2</sup>.
Injection biomechanics of bone cements used in vertebroplasty (2004)

The incidence of osteoporotic bone fractures is growing exponentially as the western population ages and as life expectancy increases. Vertebroplasty, where acrylic or calcium phosphate cement is injected into the weakened vertebrae to augment them, is an emerging procedure for treating spinal fragility fractures. However, cement injection is currently limited because there are no clear standards for a safe, reproducible and predictable procedure. The purpose of this paper is to examine the role that bone cements play in the underlying bio-mechanisms that affect the outcomes of cement injection. Our most important finding after combining clinical, laboratory and theoretical research is that the process of cement injection poses conflicting demands on bone cements. The cements are required to be more viscous and less viscous at the same time. The challenge therefore is to develop biomaterials, techniques and/or devices that can overcome or manage the conflicting demands on cement viscosity.
AMP-18 protects barrier function of colonic epithelial cells: role of tight junction proteins (2005)

Antrum mucosal protein (AMP)-18 and a synthetic peptide of amino acids 77-97 have mitogenic and motogenic properties for epithelial cells. The possibility that AMP-18 is also protective was evaluated in the colonic mucosa of mice and monolayer cultures of human colonic epithelial Caco-2/bbe (C2) cells. Administration of AMP peptide to mice with dextran sulfate sodium (DSS)-induced colonic injury delayed the onset of bloody diarrhea and reduced weight loss. Treatment of C2 cells with AMP peptide protected monolayers against decreases in transepithelial electrical resistance induced by the oxidant monochloramine, indomethacin, or DSS. A molecular mechanism for these barrier-protective effects was sought by asking whether AMP peptide acted on specific tight junction (TJ) proteins. Immunoblots of detergent-insoluble fractions of C2 cells treated with AMP peptide exhibited increased accumulation of specific TJ proteins. Occludin immunoreactivity was also increased in detergent-insoluble fractions obtained from colonic mucosal cells of mice injected with AMP peptide. Observations using laser scanning confocal (CF) microscopy supported the capacity of AMP peptide to enhance accumulation of occludin and zonula occludens-1 in TJ domains of C2 cell monolayers and together with immunoblot analysis showed that the peptide protected against loss of these TJ proteins following oxidant injury. AMP peptide also protected against a fall in TER during disruption of actin filaments by cytochalasin D and stabilized perijunctional actin during oxidant injury when assessed by CF. These findings suggest that AMP-18 could protect the intestinal mucosal barrier by acting on specific TJ proteins and stabilizing perijunctional actin.
Prospects for Millimeter-Wave Compliance Measurement Technologies [Measurements Corner] (2017)

In recent years, there has been an increasing interest in millimeterwave (mm-wave) technologies operating at frequencies between 10 and 300 GHz. mm-wave communication provides higher transfer rates that will be employed in the next-generation wireless networks. However, mm-wave device exposure compliance assessment is challenging due to a reduced wavelength and an increased number of antennas. In this article, we discuss physical features of future mmwave communication networks and describe the requirements for proper exposure compliance assessment. Leading technologies that can be prospectively used for mm-wave exposure compliance are surveyed. Their pros and cons with respect to operating frequency, availability, sensitivity, and speed are discussed.
Lateral Merging Continuous Inkjet (2011)

Continuous inkjet (CIJ) devices that use more than one nozzle to form a single droplet are reported. The experimentally studied devices contain a pair of interactive nozzles that are used to form ink drops with large and small volumes by thermally stimulating a liquid jet at each nozzle, causing controlled breakup. Resistive heaters located around each nozzle are used for both thermal stimulation and for controlling the direction of the ink stream from each nozzle. Under proper conditions, the large drops formed from each nozzle in the pair touch each other and merge laterally, while the small drops from each pair of nozzles remain separate. The lateral merging CIJ system offers a potential for even greater speed advantages and higher image quality than existing singlenozzle Kodak Stream inkjet technology, a continuous inkjet system. Details on design, fabrication, and characterization of the lateral merging CIJ device are provided, including results from experimental studies.
Ultrasound intensity to propel stones from the kidney is below the threshold for renal injury (2013)

Therapeutic ultrasound has an increasing number of applications in urology, including shockwave lithotripsy, stone propulsion, tissue ablation, and hemostasis. However, the threshold of renal injury using ultrasound is unknown. The goal of this study was to determine kidney injury thresholds for a range of intensities between diagnostic and ablative therapeutic ultrasound. A 2 MHz annular array generating spatial peak pulse average intensities (ISPPA) up to 28,000 W/cm2 in water was placed on the surface of in vivo porcine kidneys and focused on the adjacent parenchyma. Treatments consisted of pulses of 100 μs duration triggered every 3 ms for 10 minutes at various intensities. The perfusion-fixed tissue was scored by 3 blinded independent experts. Above a threshold of 16,620 W/cm2, the majority of injury observed included emulsification, necrosis and hemorrhage. Below this threshold, almost all injury presented as focal cell and tubular swelling and/or degeneration. These findings provide evidence for a wide range of potentially therapeutic ultrasound intensities that has a low probability of causing injury. While this study did not examine all combinations of treatment parameters of therapeutic ultrasound, tissue injury appears dose-dependent.
Immune Status of Infants Fed Soy-Based Formulas With or Without Added Nucleotides for 1 Year: Part 2: Immune Cell Populations (2002)

Infants fed this commercial soy formula demonstrated immune cell status similar to human milk/formula-fed infants, consistent with normal immune system development. The addition of nucleotides to soy formula did not significantly change specific individual immune cell populations but tended to increase numbers and percentages of T cells and decreased numbers and percentages of NK cells.
Sequential Shrinkage and Swelling Underlie P2X7-Stimulated Lymphocyte Phosphatidylserine Exposure and Death (2008)

Patterns of change in cell volume and plasma membrane phospholipid distribution during cell death are regarded as diagnostic means of distinguishing apoptosis from necrosis, the former being associated with cell shrinkage and early phosphatidylserine (PS) exposure, whereas necrosis is associated with cell swelling and consequent lysis. We demonstrate that cell volume regulation during lymphocyte death stimulated via the purinergic receptor P2X7 is distinct from both. Within seconds of stimulation, murine lymphocytes undergo rapid shrinkage concomitant with, but also required for, PS exposure. However, within 2 min shrinkage is reversed and swelling ensues ending in cell rupture. P2X7-induced shrinkage and PS translocation depend upon K+ efflux via KCa3.1, but use a pathway of Cl- efflux distinct from that previously implicated in apoptosis. Thus, P2X7 stimulation activates a novel pathway of cell death that does not conform to those conventionally associated with apoptosis and necrosis. The mixed apoptotic/necrotic phenotype of P2X7-stimulated cells is consistent with a potential role for this death pathway in lupus disease.
A study of [Au(ethylenediamine)Cl2]Cl interaction with L-methionine and DL-seleno-methionine by1H and13C NMR spectroscopy (2010)

The interaction of [Au( en )Cl 2 ]Cl with L-methionine (Met) and DL-seleno-methionine (Se-Met) was carried out in D 2 O solution at ∼pH 3.8. 13 C NMR spectra were interpreted by comparison with the spectra recorded after the reaction of Met or Se-Met with HAuCl 4 and also after oxidation by H 2 O 2 . Reactions of [Au( en )Cl 2 ]Cl with Met and Se-Met were found to proceed through the exchange of chloride ligands from complex with Met or Se-Met. Gold(III) reduction takes place during the reaction and en ligand was released from [Au( en )Cl 2 ]Cl complex.
Selective Sorption of Nanoporous Poly(methyl silsesquioxane) (2002)

The sorption behavior of nanoporous poly(methyl silsesquoxane), PMSSQ, thin films was investigated using a quartz crystal microbalance (QCM) combined with reflectance infrared spectroscopy (IR). The nanoporous PMSSQ films are intrinsically hydrophobic and show highly selective sorption behavior. With organic liquids having surface tensions below the critical value (38−48 dyn/cm), the extent of sorption increased with porosity of PMSSQ films. Extremely low amounts of sorption were measured with liquids having a surface tension higher than the critical value. The selective sorption behavior can be interpreted by capillary condensation resulting from the lowered vapor pressure in the nanoscopic pores.
Role of resistin in diet-induced hepatic insulin resistance (2004)

Resistin is an adipose-derived hormone postulated to link adiposity to insulin resistance. To determine whether resistin plays a causative role in the development of diet-induced insulin resistance, we lowered circulating resistin levels in mice by use of a specific antisense oligodeoxynucleotide (ASO) directed against resistin mRNA and assessed in vivo insulin action by the insulin-clamp technique. After 3 weeks on a high-fat (HF) diet, mice displayed severe insulin resistance associated with an approximately 80% increase in plasma resistin levels. In particular, the rate of endogenous glucose production (GP) increased more than twofold compared with that in mice fed a standard chow. Treatment with the resistin ASO for 1 week normalized the plasma resistin levels and completely reversed the hepatic insulin resistance. Importantly, in this group of mice, the acute infusion of purified recombinant mouse resistin, designed to acutely elevate the levels of circulating resistin up to those observed in the HF-fed mice, was sufficient to reconstitute hepatic insulin resistance. These results provide strong support for a physiological role of resistin in the development of hepatic insulin resistance in this model.
AutoConnect (2015)

We present AutoConnect, an automatic method that creates customized, 3D-printable connectors attaching two physical objects together. Users simply position and orient virtual models of the two objects that they want to connect and indicate some auxiliary information such as weight and dimensions. Then, AutoConnect creates several alternative designs that users can choose from for 3D printing. The design of the connector is created by combining two holders, one for each object. We categorize the holders into two types. The first type holds standard objects such as pipes and planes. We utilize a database of parameterized mechanical holders and optimize the holder shape based on the grip strength and material consumption. The second type holds free-form objects. These are procedurally generated shell-gripper designs created based on geometric analysis of the object. We illustrate the use of our method by demonstrating many examples of connectors and practical use cases.
Integrated monitoring system to assess LV flexibility impact (2020)

This study describes the strategic benefits for Electronic Data Processing (EDP) Distribution of implementing an integrated monitoring system in the low-voltage (LV) side of secondary substations. This system means a step forward in the digitalisation of the LV grid which acts in conjunction with on-going smart grid appliances, growing up synergies between them and allowing better visibility in this part of the grid. The monitoring system consists of the measurement of each LV circuit, integrating and processing the data in an online platform. With these measurements, along with smart grid data, there are proposed four use cases: (i) LV asset condition monitoring; (ii) network power quality; (iii) grid topology identification; (iv) energy balance. This study sums up the highlights and initial conclusions of testing this solution for almost a year, including specific results for each use case, benefits and future recommendations for adopting this solution as a rollout.

An Optimized 5 kW, 147 W/in<sup>3</sup> Telecom Phase-Shift DC-DC Converter with Magnetically Integrated Current Doubler (2009)

In the last decade there has been a tremendous growth in the number of data centers due to the increasing demand for Internet services. At the same time, the cost for energy and materials have increased because of reducing resources and increased demand. That has caused a change in the driving forces for new power supply development, with more consideration on power density and efficiency. The commonly used DC-DC converter in the power supply unit (PSU) for data centers and telecom applications are full bridge phase-shift converters since they meet the demands of high power levels and concurrently efficient power conversion as well as a compact design. The constant operating frequency allows a simple control and EMI design. To develop a new converter with higher power density and/or high efficiency the designer has a lot of degrees of freedom. An optimization procedure, based on comprehensive analytical models, has been developed and leads to the optimal parameters (e.g. switching frequency or transformer design) to achieve the most compact and/or efficient design. In this paper an volume optimized 400 V/48 V phase-shift DC-DC converter with current doubler rectifier based on analytical models is constructed. The power density of the converter is increased by integrating the output inductors in the transformers core. The intrinsic voltage ringing of the rectifier diodes is damped by a lossless magnetic snubber, which feeds ringing energy to the output. Experimental results prove the theoretical analytical models and the design procedure.
Detection of Circulating CEA-IgM Complexes in Early Stage Colorectal Cancer (2005)

We have recently shown that alpha fetoprotein (AFP) and squamous cell carcinoma antigen (SCCA), biomarkers associated with hepatocellular carcinoma, may be detected in patient sera as circulating immune complexes with IgM, and that assessment of serum levels of AFP-IgM and SCCA-IgM may be used for the detection of liver cancer. In this study we measured the levels of carcinoembryonic antigen (CEA) as free form (FCEA) and complexed to IgMs (CEA-IgM) in sera of patients affected by colorectal carcinoma (CRC) at different stages as well as in healthy subjects. FCEA levels were above the 5 ng/mL cutoff in 43% of CRC patients (31/72) and CEA-IgM levels were above the 200 AU/mL cutoff in 38% of CRC patients (27/72). Serum levels of CEA-IgM immune complexes (IC) and FCEA did not overlap and 64% of patients (46/72) were positive for at least one marker without compromising the detection specificity (94%). Early detection of CRC was significantly improved by CEA-IgM IC assay. CRC patients at an early stage (stage 1) had elevated CEA-IgM levels in 29% of cases (7/24), while FCEA levels were elevated in only 8% of cases (2/24). These results indicate that CEA-IgM is a complementary serological marker to FCEA which is much more sensitive for early stage CRC, and that the combination of these biomarkers may be useful in the early detection of colorectal cancer.
Antimicrobial dressing efficacy against mature Pseudomonas aeruginosa biofilm on porcine skin explants (2013)

An ex vivo porcine skin explant biofilm model that preserves key properties of biofilm attached to skin at different levels of maturity (0-3 days) was used to assess the efficacy of commercially available antimicrobial dressings and topical treatments. Assays were also performed on the subpopulation of antibiotic tolerant biofilm generated by 24 hours of pre-treatment with gentamicin (120× minimal inhibitory concentration) prior to agent exposure. Five types of antimicrobial agents (iodine, silver, polyhexamethylene biguanide, honey and ethanol) and four types of moisture dressings (cotton gauze, sodium carboxymethylcellulose fibre, calcium alginate fibre and cadexomer beads) were assessed. Time-release silver gel and cadexomer iodine dressings were the most effective in reducing mature biofilm [between 5 and 7 logarithmic (log) of 7-log total], whereas all other dressing formulations reduced biofilm between 0·3 and 2 log in 24 or 72 hours with a single exposure. Similar results were found after 24-hour exposure to silver release dressings using an in vivo pig burn wound model, demonstrating correlation between the ex vivo and in vivo models. Results of this study indicate that commonly used microbicidal wound dressings vary widely in their ability to kill mature biofilm and the efficacy is influenced by time of exposure, number of applications, moisture level and agent formulation (sustained release).
Optimisation of Lumped Element Kinetic Inductance Detectors for use in ground based mm and sub-mm arrays (2009)

The Lumped Element Kinetic Inductance Detector (LEKID) is a single layer superconducting detector which provides a simple and elegant solution for producing large format, multiplexed arrays of background limited detectors for ground based astronomy. The LEKID design incorporates both the detecting element and absorber of an array pixel which does not require feed‐horns or antennas to couple in light from a telescope. In order to achieve good optical efficiency across an atmospheric window, the geometry and material choice of the LEKID need to suit the observing band of interest. In addition to this, the geometric and frequency spacing of LEKIDs in an array needs to be optimised to limit crosstalk between pixels and make full use of the bandwidth of the multiplexed readout electronics. In this paper we discuss each of these design aspects of the LEKID and present results for LEKID pixels designed to work at 200 um and 2mm.
