A novel differential phase method to measure phase pattern and phase center of a horn antenna at 110 GHz (1990)

The phase center location and the phase pattern for a 110 GHz corrugated horn were measured by a novel differential phase method. This method makes it possible to overcome problems associated with the complexity of the measurement setup and errors caused by the flexible cable or rotary joint required in the system. The phase center at 110 GHz is 2.7+or-0.3 mm from the aperture. The measurements agree very well with the results given by the modal matching technique. This technique predicts very accurately both the phase center position and the phase pattern.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Age-dependent changes in MRI of motor brain stem nuclei in a mouse model of ALS (2004)

Mice over-expressing the mutant human G93A-SOD1 are widely used as an animal model of amyotrophic lateral sclerosis (ALS). ALS is characterized by progressive degeneration of motor neurons in the motor cortex, brain stem and spinal cord. The underlying mechanisms for the selective death of motor neurons are still uncertain. To study factors that cause selective neuron degeneration or therapeutic approaches to delay the progression of the disease, a method is required to monitor the state of motor neurons under in-vivo conditions. Here, we demonstrate that in G93A-SOD1 mice the MRI signal intensities of nucleus V, VII, XII, and nucleus ambiguus show a time-dependent increase starting around day 90, parallel to first behavioral signs of a motoneuron disorder.
Memory-a RAM link for high speed (1992)

Work on an open standard that defines a ring for linking fast memories and processors is discussed. The interface, called RamLink, will provide high performance even when dynamic RAMs (DRAMs) with internal caching mechanisms are ineffective. In addition to RAM, RamLink will support flash nonvolatile memory, read-only memory, and even memory-mapped disks. Mismatching, collision avoidance, and problems that must be addressed by RamLink are examined. A detailed simulation model for RamLink written in Simula, an object-oriented language, is briefly described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
A Ripple Current Reduction Method with Fast Dynamic Response for Fuel Cell Application (2004)

A new ripple current reduction method of fuel cell output for boost converter, which has no additional active filter, is proposed. In proposed method, the converter controls the ripple current as well as output voltage of the converter. A current ripple reduction pass of the control loop, which has little affection of controller, has added for fast output voltage dynamics. The dynamics of the output voltage designed very fast with only about 16 ms, which is as low as two periods of 120 Hz current ripple of inverter load. The above 
characteristics are verified by PSIM simulation.
Exaggerated Stress Responses of a Chromosome-1 Congenic Strain Derived from Shrsp/Izm and Wky/Izm (2000)

P136 Background: QTL mapping studies showed that the rat chromosome 1 includes a gene responsible for hypertension in SHR. To understand roles of this putative hypertension gene on the cardiovascular physiology, we studied stress responses of a congenic strain with the chromosome-1 blood pressure (BP) QTL transferred from SHRSP/Izm. Methods: The region between D1Wox29 and D1Rat112 (∼60cM) was introgressed from SHRSP/Izm to WKY/Izm by repeated backcrossing. The established congenic strain (CONG) covered a 100:1 support interval for the BP QTL found in the previous study (Am J Hypert 1999;12:1098). After telemetry probes were implanted, age-matched male CONG and WKY (5-6 month old) were used in the following experiments; 1) Restraint stress: rats were put in small tubes for 1h at room temperature and BP was monitored with radiotelemetry. 2) Cold stress: rats were kept at 4 C for 2h and BP was monitored using telemetry. Results: Without the stresses, BP measured with telemetry was not different between WKY and CONG (Table) although tail-cuff measurement gave a significant difference in BP between the two strains (141±3.5 and 154±8.3mmHg for WKY and CONG, p
Multichannel InSAR DEM reconstruction through closed-form robust Chinese remainder theorem (2012)

Interferometric synthetic aperture radar (InSAR) multichannel system, based on the collection of more interferograms acquired in a multifrequency or in a multibaseline configuration, allows us to reconstruct highly sloped and discontinuous terrain height profiles. In this paper, we present a new method to solve the digital elevation model (DEM) reconstruction problem using the closed-form robust Chinese remainder theorem (CRT). This method uses the remainder differential process, which does not exist in the traditional CRT, to improve the robustness of the DEM reconstruction. The simulation results demonstrate that the performance of the proposed method is better than statistical methods such as maximum likelihood (ML) estimation techniques, when the number of independent interferograms does not large enough.
Three dimensionally printed pearl powder/poly-caprolactone composite scaffolds for bone regeneration (2018)

Pearl has great potential as a natural biomaterial for bone tissue engineering, but it suffers from low porosity, difficulty in molding, and poor anti-buckling property. In this study, we used the 3-D printing technique to fabricate original pearl powder and PCL composite scaffolds with different concentrations of pearl powder. The four groups of scaffolds were termed PCL, 30% Pearl/PCL, 50% Pearl/PCL and 80% Pearl/PCL scaffolds according to the proportion of pearl powder. The samples were systematically investigated by scanning electron microscopy (SEM), wide-angle XRD, liquid substitution, Zwick static materials testing, and energy dispersive X-ray analysis. Biological characterization included SEM, fluorescent staining using calcein-AM, cell counting kit-8 assay, alkaline phosphatase and qRT-PCR analysis. The results show that the pore size and the pore morphology of the scaffolds are closely controlled via 3-D printing. This is very beneficial for tissue growth and nutrition transmission. The regular and uniform square macropore structure ensured that the pearl powder/PCL scaffolds had favorable mechanical strength. As the concentration of pearl powder in the scaffolds increase, the compressive strength and apatite formation increase as well as cell adhesion, proliferation, and osteogenic differentiation. These results show that pearl powder/PCL scaffolds fit the requirements of bone tissue engineering. The structures as well as physicochemical and biological properties of pearl powder/PCL composite scaffolds are positively associated with pearl powder concentrations.
Accumulation of 74As51Cr β-glycerophosphate by Normal Lymph Nodes (1969)

51Cr β-glycerophosphate accumulates actively in different types of tumors. The experiments reported here demonstrate that radioarsenic can be incorporated into this particular chromium complex without significant alteration in its metabolic behavior. After subcutaneous administration of radioarsenic-chromic-β-glycerophosphate complex in the rat, there is significant concentration of radioactivity in normal lymph nodes. The degree of accumulation of this complex by normal and tumor tissue is affected by the extent of polymerization of the compound prior to injection. This compound may be useful for the evaluation of neoplastic involvement of nonaccessible lymph nodes.
Single-shot characterization of vector beams by generalized measurements (2022)

Vector vortex beams, featuring independent spatial modes in orthogonal polarization components, offer an increase in information density for emerging applications in both classical and quantum communication technology. Recent advances in optical instrumentation have led to the ability of generating and manipulating such beams. Their tomography is generally accomplished by projection measurements to identify polarization as well as spatial modes. In this paper we demonstrate spatially resolved generalized measurements of arbitrary vector vortex beams. We perform positive operator valued measurements (POVMs) in an interferometric setup that characterizes the vector light mode in a single-shot. This offers superior data acquisition speed compared to conventional Stokes tomography techniques, with potential benefits for communication protocols as well as dynamic polarization microscopy of materials.
Resveratrol increases FOXO3 transcriptional activity and expression of FOXO3 target genes. (2015)

&lt;p&gt;(a) FOXO3 transcriptional activity was assessed using the Fork Head Responsive Element (FHRE) reporter gene assay. Cells were grown in 24-well plates and transfected with the reporter plasmid at 40–50% confluence. The assay was performed 48 hrs. later. On the day of the assay, the cells were treated with H&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt; ± resveratrol for 6 hrs. after which they were harvested and luciferase activity was measured. Resveratrol induced a twofold increase in FOXO3 transcriptional activity. (b) The cells were incubated with the indicated concentrations of resveratrol for 30 minutes and harvested 16 hrs. later. mRNA levels were quantified by real-time PCR. Among the known FOXO3 target genes, expression of catalase (CAT) and BCL2-like 11 (BCL2L11) were significantly increased with 25 µM and 50 µM resveratrol and cell-cycle checkpoint protein cyclin G2 (CCNG2) and proapoptotic protein PUMA (BBC3) were increased by 50 µM resveratrol. * indicates p&lt;0.05 compared to 0 µM resveratrol treatment.&lt;/p&gt;
In‐Situ Structure Control of Ceramic Composite with Improved Mechanical Properties and Remote Sensing for Crack Propagation (2000)

Novel Ce-TZP based composites were successfully developed by the microstructure control of in-situ formed plate-like Lanthanum-β-aluminate or La M-type Hexaferrite crystals via conventional powder processing and sintering procedure. Formation of the anisotropic crystals was effective to improve the mechanical properties of the composite. Composite with in-situ formed hexaferrite particles exhibits improved mechanical properties as well as magnetism, which can be applied for remote sensing of crack propagation utilizing the inverse magnetostrictive effect.

Physical and mechanical properties of rigid polyurethane foams modified with polystyrene beads (2012)

Abstract This study presents a method of obtaining porous materials based on the rigid polyurethane foam (RPURF) as the matrix and containing thermoplastic polystyrene beads (EPS) as the fillers. In RPURF-EPS composites, the compact EPS were expanded after heating above a glass transition temperature of the EPS and gas vapouring incorporated inside the EPS, by using heat of exothermic reaction of polyol with isocyanate. The thermal conductivity, compressive strength, core density and cell structure of the new materials were investigated

B. mechanische Belastungen beim Handhaben oder die Bestrahlung mit hellem Weißlicht während des Mikroskopiervorgangs wurden in der vorliegenden Studie erstmals evaluiert.
Cytomegalovirus (CMV) infection in AIDS patients is associated with a CD3 receptor-mediated T cell hyporesponsiveness (1998)

HIV+ individuals with human CMV (HCMV) reactivation have a CD3 receptor-mediated T cell hyporesponsiveness when compared with CD4-matched HIV+ and HCMV- control groups. The impairment of proliferation was not reversed by exogenous IL-2. A typical increase in NFkappaB expression was observed following cross-linking of the CD3 receptor, but did not lead to increased CD25 cell surface expression or cell proliferation. The HCMV-induced non-responsiveness was not observed when cells were stimulated with phorbol esters. Lymphocytes cultured with media collected from cell cultures infected with HCMV showed a dose-dependent inhibition in the total T cell population even though cells staining dually for CD8/57 increased in number. The altered growth factor requirements of CD8/57+ cells may therefore account for their presence in AIDS and patients following bone marrow transplantation.
Fermentation characteristics of yeast suitable for high-sugar dough (2016)

Three kinds of baker’s yeasts (Saccharomyces cerevisiae), 1-2, 9-3 and 10-2 were isolated from fruits or humus to bake bread in high-sugar dough. Their fermentation test and sensory evaluation of beard baked in 30%-sucrose dough were examined. The results of the fermentation test with 20-40% glucose added to the medium showed that CO2 production by the wild yeast (10-2) isolated from apple leaves was highest among the three strains. The strain that showed the highest alcohol producing ability was 9-3, which was isolated from nectarine seeds.
An Overview of Recent Research in the Conversion of Glycerol into Biofuels, Fuel Additives and other Bio-Based Chemicals (2018)

The depletion of fossil fuels has heightened research and utilization of renewable energy such as biodiesel. However, this has thrown up another challenge of significant increase in its byproduct, glycerol. In view of the characteristics and potentials of glycerol, efforts are on the increase to convert it to higher-value products, which will in turn improve the overall economics of biodiesel production. These high-value products include biofuels, oxygenated fuel additives, polymer precursors and other industrial bio-based chemicals. This review gives up-to-date research findings in the conversion of glycerol to the above high-value products, with a special focus on the performance of the catalysts used and their challenges. The specific products reviewed in this paper include hydrogen, ethanol, methanol, acetin, glycerol ethers, solketal, acetal, acrolein, glycerol carbonate, 1,3-propanediol, polyglycerol and olefins.
A Wearable System Based on Flexible Sensors for Unobtrusive Respiratory Monitoring in Occupational Settings (2020)

Workers experiencing high levels of stress may suffer from poor motivation, low level of attention, and physical disorders which, in turn, may lead to work injuries. Respiratory frequency (f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R</sub> ) is considered one of the most reliable indicators of the mental load and fatigue state of workers. Monitoring this parameter through wearable devices represents an efficient solution for the maintenance of Occupational Health and Safety. We developed an innovative wearable system equipped with flexible sensors based on fiber Bragg gratings (FBGs) to monitor f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R</sub> in static and dynamic conditions characterizing occupational settings. This article provides a description of the system and of the metrological characteristics of the flexible sensors in terms of response to strain and temperature changes, and hysteresis error. The performances of the device, evaluated in a laboratory during the execution of tasks mimicking real work activity, are also reported. The obtained promising results encourage the engineering of the system for use in real workplaces to collect quantitative information on the psychophysical state of workers and its relation to stress level.

WET SPINNING OF NYLON 3 (1970)

Nylon 3 was-spun in the ethyl acetate coagulation bath, using formic acid as the dope solvent. Spinning conditions, especially the drawing conditions were investigated.Boiling water, steam and glycerine, which are well-known drawing medias for ordinary polyamides were not suitable as the drawing media for nylon 3 fibers. While in such media as silicone oil, wood's metal or hot air, which are thought to have no interaction with polyamides, nylon 3 fibers were able to be stretched above the glass transition temperature (170_??_180°C). The drawn nylon fibers thus obtained showed fairly good mechanical properties as textile fibers, i. e. strength, 2_??_3g/d, elongation; 10_??_20%.Relations between mechanical properteis and spinning conditions were also investigated. Mechanical properties of drawn nylon 3 fibers thus obtained were not so much affected by coagulation conditions and spinning dope conditions, but remarkably affected by drawing conditions.
Study of electrically active lattice defects in Cf-252 and proton irradiated silicon diodes (1992)

The results of a comparative study of electrically active damage introduced in silicon diodes by irradiation with the fission products of a Cf-252 source and with high-energy protons are presented. The influence of substrate doping, oxygen content, and thermal pretreatments on the damage formation is investigated using electrical evaluation of the diode characteristics correlated with deep level transient spectroscopy investigations. Both types of irradiation create the same dominant defect types but with different efficiencies and relative densities. A radiation hardening effect by interstitial oxygen is observed. Both the leakage current and the deep level density show a linear dependence on the irradiating particle fluence.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Battery state estimation for applications in intelligent warehouses (2011)

When it comes to AGVs (Automated Guide Vehicles) working in intelligent warehouse systems it is necessary to take into account that the use of batteries may impact the performance of the overall system. They need to be recharged or changed, and the time required to execute these operations might interfere in the AGV availability. Therefore, it is necessary to carry out a battery management procedure to ensure that the batteries have sufficient charges to perform the desired tasks. This paper describes a method based on the Extended Kalman Filter (EKF) to estimate the Batteries State of Charge (SOC). The estimated consumption is compared with the SOC obtained by the EKF. A series of experiments using mini-robotic forklifts were performed to evaluate the method. The experimental results have shown its effectiveness using resistive loads. This methodology allowed estimating the battery consumption for a certain route of the mini-robotic forklift in the warehouse and verifying the load capacity available for the mini-robotic forklift to accomplish a task assigned by the warehouse routing system.
Emission of Electromagnetic Pulses from Laser Wakefields through Linear Mode Conversion (2005)

Powerful coherent emission around the plasma oscillation frequency can be produced from a laser wakefield through linear mode conversion. This occurs when the laser pulse is incident obliquely to the density gradient of inhomogeneous plasmas. The emission spectrum and conversion efficiency are obtained analytically, which are in agreement with particle-in-cell simulations. The emission can be tuned to be a radiation source in the terahertz region and with field strengths as large as a few GV/m, suitable for high-field applications. The emission also provides a simple way to measure the wakefield produced for particle acceleration.
