Simultaneous Frequency and Isolation Reconfigurable MIMO PIFA Using PIN Diodes (2012)

A reconfigurable multiple input multiple output (MIMO) planar inverted-F antenna (PIFA) is presented for three worldwide m-WiMAX bands: 2.3-2.4 GHz, 2.5-2.7 GHz, and 3.4-3.6 GHz. In order to achieve low mutual coupling, i.e., high isolation, a band-notched quarter-wave slot line on the ground plane is used between the two reconfigurable antennas. Two PIN-diodes are appropriately located on the slot line in order to electrically control the slot length. By adjusting both the PIN-diode biases for the reconfigurable antennas and the reconfigurable isolation slot, the proposed antenna simultaneously obtains the operating frequency and isolation reconfigurability for the three operating bands. A parametric analysis is performed to investigate optimized slot lengths for the three operation modes. All of the simulated results are confirmed with measurements. Measured isolation performance of greater than 30 dB improves the radiation efficiency, diversity gain, and channel capacity for all operating frequencies.
Nonlinear Controller Design for Vehicle-to-Grid Systems with Output LCL Filters (2015)

This paper presents a nonlinear controller design for vehicle-to-grid (V2G) systems with LCL output filters. The V2G systems are modeled with LCL output filters in order to eliminate harmonics for improving power qualities and the nonlinear controller is designed based on the feedback linearization. The feasibility of using the appropriate feedback linearization approaches, either partial or exact, is also investigated through the feedback linearizability of V2G systems. In this paper, partial feedback linearization is used to design the controller with a capability of sharing both active and reactive power in V2G systems. The performance of the proposed controller controller is evaluated on a single-phase full-bridge converter-based V2G system with an LCL output filter and compared to that of without any filter. Simulation results clearly demonstrate the harmonic elimination capabilities of the proposed V2G structure with the proposed control scheme.
Relationship between specific temporomandibular disorders and impaired upper neck performance (2020)

Upper neck impairments are more prevalent in patients with temporomandibular disorders (TMDs) but the differences between specific types of TMDs are unclear. This study evaluated the distribution of such impairments among different forms of TMD. In total, 116 participants (86 women and 30 men, age range 21-75 yr) were investigated. Forty-two individuals had no TMDs and were assigned to the control group. The remaining 74 patients were assigned to one of three groups based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) findings: pain-related (n = 37); intra-articular (n = 17); or mixed (combined pain-related and intra-articular) (n = 20). Analyses of impairments included between-group comparisons of key parameters of upper neck performance (active/passive mobility and muscular capabilities) and pain (subjective neck disability and pain sensitivity). Patients in the pain-related and mixed TMD groups were found to have decreased upper neck mobility in the cervical flexion-rotation test compared with patients in intra-articular and control groups, as well as poorer capabilities of the deep neck flexor muscles in the cranio-cervical flexion test compared to the control group. It was concluded that patients with pain-related TMD diagnoses are more likely to experience significant upper-neck hypomobility and poor muscular capabilities than patients with intra-articular diagnoses of TMD.
Reactions of alkali metal atoms with carbon tetrachloride. Rainbow-like coupling of product angle and energy distributions (1979)

Velocity distributions of alkali metal chlorides reactively scattered from crossed thermal beams of K, Rb or Cs and CCl4 have been measured over the range 100–1000 m s–1 at laboratory angles from 10 to 100° with respect to the parent alkali beam. The differential cross sections for reactive scattering in the centre-of-mass system show strong coupling between the peak position of the product angular distribution [graphic omitted] and the final relative translational energy E′, and vary markedly with the identity of the alkali metal atom. For a given alkali metal, [graphic omitted] shifts to smaller angles as E′ increases, and as K → Rb → Cs the entire pattern shifts toward the forward hemisphere. These properties suggest an analogy to the rainbow effect familiar in elastic scattering. The product distributions can be simulated by a simple dynamical model. The most important features are the reaction probability as a function of initial impact parameter, the repulsive force causing dissociation of the unstable CCl4– intermediate formed by transfer of the alkali metal valence electron, and the T → V, R energy transfer induced by release of this repulsion during formation of the product bond. The product velocities obtained 25 years ago for Cs + CCl4 by Bull and Moon agree with our data within ≈ 10%.
Traumatic and Non-traumatic Osteonecrosis in the Femoral Head of a Rabbit Model (2011)

Osteonecrosis of the femoral head is an idiopathic, debilitating and progressive disease. A number of traumatic or non-traumatic animal models have been reported for research on osteonecrosis. This study was performed to compare the efficacy of femoral head osteonecrosis in rabbits by traumatic and non-traumatic methods. Twenty-seven New Zealand White rabbits were divided into three experimental groups, nine heads each. Two groups were surgically induced into osteonecrosis; a steel cerclage wire was ligated tightly around the neck of the right femoral head (Group W), and the femoral neck was tied with a cerclage wire in the same way as in the W group, and burned by attachment of an electrode tip to the wire and then the wire was removed (Group B). The other group was induced into osteonecrosis with a single intra-muscular injection of 20 mg/kg methyl-prednisolone acetate single injection (Group M). In the control group, the left femoral head of animals in group W and B was used. After two weeks, rabbits were sacrificed and the femoral head and neck were collected. Osteonecrosis of the femoral head was evaluated by radiography, histology and immunohistology methods. Osteonecrosis lesions in the femoral head were identified in traumatic models of groups W and B. Cartilage degeneration in the superficial layer and TUNEL positive cells in the femoral head were detected more in Group B than in Group W. These findings revealed that short-term induced osteonecrosis of the femoral head was effectively achieved by cautery around the femoral neck.
Low liquid–solid ratio (LSR) hot water pretreatment of sugarcane bagasse (2012)

Low liquid–solid ratio (LSR) can be used to obtain high-content xylo-oligosaccharide (XOS) spend liquor by hot water pretreatment. Developing a technology based on low LSR results in more efficient water usage in the system and thus in lower capital and operating costs. Xylans from xylan rich agro-industrial waste are abundant hemicellulosic polymers with enormous potential for industrial applications. Currently, freeze-dried xylo-oligosaccharides are used as bio-based polymers and hydrolysates containing high xylose contents are converted to several chemical products. In this study, sugarcane bagasse was treated with water at low LSRs and mild temperatures in order to assess the effects of varying the pretreatment conditions on the xylo-oligosaccharide and xylose concentrations, and use a central composite experimental design to optimize the process parameters. The pretreatments were performed in the ranges temperature: 143.3–176.7 °C, time: 20–70 min and LSR: 1 : 1 to 11 : 1 (g g−1). The maximum concentrations of xylose and xylan were 13.76 and 36.18 g L−1 (equivalent to 48.29 g L−1 of xylan), respectively, which were achieved by treating bagasse at 170 °C for 60 min, with LSR of 3 g g−1. The amount of xylan removed under these conditions was almost 57%. The soluble xylan consisted mainly of xylo-oligosaccharides (74 wt% of the identified compound in the spent liquor).
The Threat from the North: Reflections on a theme both ancient and modern. (2005)

In this chapter, the author explores the way in which Jeremiah challenges the presumption that God will defend Jerusalem against invaders by seeing invasion from the north as retribution for idolatry. This historical and geographical exporation becomes a metaphor for Australians assessing their relationship to 'the north'.
Noncontact level sensing technique using computer vision (2002)

Various types of sensors have been developed for measuring the depth of liquids in tanks, such as a fuel tank in an aircraft. Almost all of these methods require the sensor to come in contact with the liquid with low-voltage electrical leads carrying the signal from the sensor to an external computer for processing. A particular concern when such in-contact sensors are used in fuel tanks is the potential for an electrical discharge through the sensor leads resulting in an explosion. In this paper, we propose a computer vision-based noncontact technique for measuring the level of a liquid in a closed container using an optical imaging system coupled with an appropriate set of image-processing algorithms. An experimental setup was specially designed and constructed for simulating the environment of vibrating fuel in the gas tank of aircrafts for demonstrating the effectiveness of the technique. The experimental results of this paper may be used for studying the feasibility of implementing an actual system, which could be incorporated in aircrafts as a part of the aircraft's fuel gauge system.
Incorporation of carbon dioxide into phthalides via ligand-free copper-catalyzed direct carboxylation of benzoxasiloles (2017)

The synthesis of a wide range of phthalides was achieved through a copper-catalyzed carboxylation reaction of benzoxasiloles.
Representing TCP/IP connectivity for topological analysis of network security (2003)

The individual vulnerabilities of hosts on a network can be combined by an attacker to gain access that would not be possible if the hosts were not interconnected. Currently available tools report vulnerabilities in isolation and in the context of individual hosts in a network. Topological vulnerability analysis (TVA) extends this by searching for sequences of interdependent vulnerabilities, distributed among the various network hosts. Model checking has been applied to the analysis of this problem with some interesting initial results. However previous efforts did not take into account a realistic representation of network connectivity. These models were enough to demonstrate the usefulness of the model checking approach but would not be sufficient to analyze real-world network security problems. This paper presents a modem of network connectivity at multiple levels of the TCP/IP stack appropriate for use in a model checker. With this enhancement, it is possible to represent realistic networks including common network security devices such as firewalls, filtering routers, and switches.
Distinguishing suitable biotypes ofDactylopius tomentosus(Hemiptera: Dactylopiidae) for biological control ofCylindropuntia fulgidavar.fulgida(Caryophyllales: Cactaceae) in South Africa (2009)

Cylindropuntia fulgida (Engelmann) F.M. Knuth var. fulgida (Engelmann) F.M. Knuth (Cff) (Caryophyllales: Cactaceae) is native to Mexico and Arizona and was introduced into South Africa for ornamental purposes. It subsequently became highly invasive, necessitating control. The cochineal insect, Dactylopius tomentosus (Lamarck) (Hemiptera: Dactylopiidae), was selected as a potential biological control agent based on its restricted host range among Cylindropuntia species and previous success in controlling C. imbricata (DC.) F. Knuth (Ci). Eight D. tomentosus provenances (Cholla, Cholla E, Fulgida, Mamillata, Imbricata, Tunicata U, Tunicata V and Rosea) from Cylindropuntia species in their native ranges were reared on Cff, whilst Cholla and Imbricata were also reared on Ci. Large differences were found in the development and survival of crawlers, and in the reproductive capacity of females. Three subjective categories of provenance interaction with host plants were identified based on a fitness index (FI) calculated from data relating to crawler survival, female development time and fecundity: (i) thriving (FI > or = 1) - insects had shorter developmental times, high crawler survival and highly fecund females (Cholla); (ii) surviving (FI<1 but >0) - insects had extended development times, low crawler survival and low fecundity (Imbricata, Fulgida and Mamillata); and (iii) dying (FI = 0) - insects died before or at the second instar (Rosea, Tunicata U and Tunicata V). Cholla, therefore, is highly suitable for biological control of Cff in South Africa. In addition, Cholla thrived on Cff but only survived on Ci whilst, in contrast, Imbricata thrived on Ci but only survived on Cff. This differential ability of provenances to thrive or survive on different host plants demonstrated that host adapted biotypes of D. tomentosus exist; therefore, biotypes should be taken into account when considering this species as a biological control agent of cactus weeds.
Funktionalität von Lecithinen (1997)

Abstract In der Industrie ist die funktionale Emulgierwirkung von Sojalecithinen von größerer technischer und kommerzieller Bedeutung, während Eilecithin eine Marktnische darstellt. Die Anforderungen an konsistente Emulgier‐, Stabilisier‐ und nutritive Eigenschaften haben neben der Standardisierung zu einerReihe von Lecithin‐Modifikationen geführt: Enzymatische Hydrolyse, Acetylierung, und Hydroxylierung ergeben Lecithine mit erhöhten hydrophilen Eigenschaften und dadurch bessere Öl‐in‐Wasser‐Emulgiereigenschaften. Alkohol‐Fraktionierung, zum Teil kombiniert mit chromatographischer Isolierung, trennt das Rohlecithin in spezifische Phospholipid‐Fraktionen, wodurch die Eigenschaften für den Einsatz in spezifischen Produkten zur Geltung kommen. Die Entölung von Rohlecithin zu „Reinlecithin”︁ mit pulverförmiger oder Granulatkonsistenz wird wegen bequemer Dosierung, neutralem Geschmack und verstärkter O/W Emulgierwirkung durchgeführt. Kombinationen dieser Verfahren ergeben eine breile Skala an Speziallecithinen mit unterschiedlichen „Hydrophile‐Lipophile‐Bilanz”︁‐Eigenschaften für den Nahrungsmittel‐ und Tierernährungssektor, Pharmazie, Kosmetik und technische Industrie.

Motivating Strategic Alliance for Composite Information Systems: The Case of a Major Regional Hospital (1989)

:This paper explores the nature of strategic goals underlying composite information systems (CIS) and ways to increase their likelihood of success. It studies a major regional hospital and its relationship with its physicians as part of a case study for providing physicians and staff convenient interface to disparate hospital departments. This situation is a particularly appropriate CIS example, involving loosely coupled and interdependent relationships (e.g., the physicians can affiliate with any hospital they want). Three approaches to motivating strategic alliances are identified: bidirectional benefits, cooperative payoffs, and asymmetrical control. Examples illustrate how these approaches were used in the design and implementation of the hospital’s CIS.
Plug-and-play adaptive optics for commercial laser scanningfluorescence microscopes based on an adaptive lens (2020)

In this Letter, we present a solution for simple implementation of adaptive optics in any existing laser scanning fluorescence microscope. Adaptive optics are implemented by the introduction of a multiactuator adaptive lens between the microscope body and the objective lens. Correction is performed with a sensorless method by optimizing the quality of the images presented on screen by the microscope software. We present the results acquired on both a commercial linear excitation confocal microscope and a custom-made multiphoton excitation microscope.
Structural analysis and stakeholder-developed scenarios for the continuous training of secondary school teachers in Barcelona (2016)

Just as teachers strive to inspire a dedication to lifelong learning in their students, educators must also continue their own learning as professionals in order to keep pace with a changing world through updates in curriculum content and pedagogical practices. In Spain, Continuous Teacher Training (CTT) programs are in place to support teachers' in this effort. However, these programs must also be reviewed and, when necessary, reimagined in order to meet teachers' needs. Using a qualitative prospective approach and structural analysis, this research provides a case study from Barcelona resulting in stakeholder-developed objectives and scenarios for improving CTT: an Ideal Scenario and a Basic Scenario. The study takes into account three underlying elements: (i) the complexity of CTT; (ii) innovation; and (iii) adoptability. While this work focuses on a specific location, the objectives and scenarios offer insight into a stakeholder-guided process for designing meaningful teacher training programs that is relevant for a broad range of education contexts
Constrained sampling for image retargeting (2008)

In this paper, we present a new approach for retargeting large images to mobile devices with small screens. As the core of image retargeting, information fidelity is adequately considered in terms of reservations of salient regions, edge integrity, and image layout. By taking these aspects as constraints, image retargeting is formulated as a constrained sampling task. Each pixel in image is first represented with a vector encoding the constraints. Then, pixels with the same vector values combine to form blocks, and the original image is thus converted into a graph representation. Thereafter, the sampling ratio of each block is determined with a balanced minimum cost flow algorithm. Final result is generated by an interpolated sampling scheme and direct scaling. Experiments demonstrate the effectiveness of the proposed approach.
Error concealment using affine transform for H.263codedvideo transmissions (2001)

A new error concealment method is proposed that uses motion estimation to consider actual motions, such as rotation, magnification, reduction, and parallel motion, in moving pictures. Since many videos include a variety of complex three-dimensional motions, the proposed method uses an affine transform to estimate the motion of lost data more accurately, thereby producing a higher peak signal-to-noise ratio value and better subjective video quality.

Dependence of Thermal Conductivities of the AlN Film in the LED Architecture on Surface Roughness and Lattice Mismatch (2013)

Thickness dependent thermal conductivity measurements were made on aluminum nitride (AlN) thin films grown by two methods on the (0001) surfaces of silicon carbide (SiC) and sapphire substrates with differing surface roughness. We find that the AlN layer itself makes a small contribution to the overall thermal resistance. Instead, the thermal boundary resistance (TBR) of 5.1±2.8 m2-K/GW between the AlN and substrate is equivalent to 240 nm of highly dislocated AlN, or 1450 nm of single crystal AlN. An order-of-magnitude larger TBR was measured between AlN films and SiC substrates with increased surface roughness (1.2 nm vs. 0.2 nm RMS). High resolution TEM images reveal near-interface planar defects in the AlN films grown on the rough SiC that we hypothesize are the source of increased TBR.
Human pituitary and placental hormones control human insulin-like growth factor II secretion in human granulosa cells. (1987)

Human granulosa cells cultured with calf serum actively proliferated for 18-20 generation and secreted progesterone into the medium; progesterone levels appeared to decline with increase in generation number. Cells cultured under serum-free conditions secreted significant amounts of progesterone and insulin-like growth factor II (IGF-II). The progesterone secretion was enhanced by the addition of human follitropin, lutropin, and chorionic gonadotropin but not by growth hormone. These cells, when challenged to varying concentrations of human growth hormone, human chorionic somatomammotropin, human prolactin, chorionic gonadotropin, follitropin, and lutropin, secreted IGF-II into the medium as measured by specific IGF-II RIA. Among these human hormones, chorionic gonadotropin, follitropin, and lutropin were most effective in inducing IGF-II secretion from these cells. When synthetic lutropin-releasing hormone and alpha-inhibin-92 were tested, only lutropin-releasing hormone was effective in releasing IGF-II. The results described suggest that cultured human granulosa cells can proliferate and actively secrete progesterone and IGF-II into the medium. IGF-II production in human granulosa cells was influenced by a multi-hormonal complex including human growth hormone, human chorionic somatomammotropin, and prolactin.
Field investigation of the effect of spectral response upon photovoltaic energy yields (2015)

The operating efficiencies of multi-junction photovoltaic cells are sensitive to changes in the spectral distribution of solar irradiance. To examine how this affects their performance in the field, two sets of triple-junction photovoltaic cells with different spectral responses are being characterised side-by-side outdoors. Initial analyses of the measurements have revealed seasonal differences between the performances of the cells that can be attributed to their spectral responses. This suggests that more long-term data will show how the choice of spectral response can impact the annual performance ratios for multijunction photovoltaic systems.
