Multilayer micromachined bandpass filter for L/S band satellite communication systems (2013)

This paper presents the design and fabrication of a 2nd order L/S band filter used as a test vehicle for the development of a fabrication technology for cavity microwave filters based on micromachining in order to preliminary explore all the technological constraints on a simpler structure. The multilayered 2nd order pseudo-elliptic L/S band filter is based on λ/4 TEM mode resonators which are patterned on a dielectric layer. For convenience 500 μm thick Si wafers have been used even if this limits the simulated Q factor of the 2nd order L/S band filter to about 200. The test structures presented here amount to the more sophisticated 4th order filters in an extended technological concept (i.e. 1500 μm thick Si wafer and two additional modules) but still based on similar resonating elements aiming to replace the existing bulky metallic waveguide filters installed in many satellite transceivers. A five mask fabrication process is employed for the realization of the elements of said filter which is based on three modules. Module A and B are fabricated on the same wafer while module C which served as ground is fabricated on a separate wafer. A 2 μm high sealing ring is etched on the back of module A and B by DRIE (Deep Reactive Ion Etching) while cavities and TSVs (Through Silicon Vias) are etched by TMAH (TetraMethylAmmonium Hydroxide). The surface mounting compatibility of the filter is obtained by adopting vertical via holes to connect the external feeding lines (e.g. microstrip or coplanar) with the filter resonators. Such a transition separates the input/output from the filter input/output coupling mechanism. The final wafers are diced and specimens are vertically stacked and bonded through thermocompression bonding. The overall filter dimensions are 48x20x1.5 mm<sup>3</sup>.

571 Clinical and Laboratory Studies of the Fate of Intranasal Allergen (2012)

BACKGROUND: The nose is generally the first site of contact for inhaled particles including allergen, however the precise way in which allergen is handled by the nose is unknown. OBJECTIVE: This study aimed to describe the dispersal of Der p 1 allergen by measuring the recovery of allergen following nasal administration and to evaluate whether Der p 1 can be detected in nasal biopsies after natural exposure and nasal challenge. METHODS: 1).. Der p 1 allergen was administered intranasal to 20 non-atopic healthy subjects and recovery of Der p 1 was measured in the nasal wash, nasal mucus and induced sputum up to 30 minutes after challenge. 2).. In 8 subjects (5 atopics) Der p 1 was sprayed intranasal into one nostril and 30 minutes later a biopsy was taken, the contralateral nostril served as a negative control. Immunohistological localisation of Der p 1, IgE positive cells, macrophages was undertaken. Eosinophils were shown by H-E staining. RESULTS: 1) Less than 25% of total allergen inserted into the nasal cavity was retrievable after aqueous or particulate allergen challenge. Most allergen was retrieved from the nasal mucus. 2).. Under baseline conditions, in atopics and non-atopics, mild Der p 1 tissue staining in nasal epithelial tissue was observed. Following challenge epithelial Der p 1 staining increased both in atopics and non-atopics, while increased staining of lamina propria was found in atopics only. Also increased eosinophils, macrophages and IgE positive cells were observed in areas of higher concentrations of Der p 1 staining in the epithelium, mucous glands and lamina propria compared to the contralateral unchallenged nasal mucosa and also compared to the nonatopics. CONCLUSIONS: Der p 1 allergen is detected in nasal tissue after natural exposure and independent of atopic status. After challenge the nose effectively retains allergen which is mucosally located. Furthermore in atopics allergen is bound to epithelial cells and rapidly transported to the subepithelial lamina propria where it can bind to IgE-bearing mast cells and recruit eosinophils and macrophages facilitating induction and persistence of inflammation.
Counseling in Catastrophic Illness: A Self-Instructional Unit (1975)

A self-instructional unit is presented to help students in the allied health fields through their initial experiences in counseling patients with serious illness. This unit is intended to be used in combination with didactic approaches. Clinically, the unit may be particularly useful for those who are learning to apply the problem-oriented record system. In the classroom situation, it may help in easing the student's thoughts and feelings into the world of the seriously or fatally ill individual. Considerable attention is given to the student's own experiences, opinions, and feelings. The unit is most effective when there is active guidance and participation from the instructor, although it is in a self-instructional format.
Modelisation et commande d'un procede de separation par extraction liquide-liquide (1992)

Nous etudions le probleme de la commande de la qualite des produits d'une cascade de melangeurs-decanteurs separant des terres rares. Nous rappelons d'abord une technique de commande developpee pour des colonnes a distiller et qui peut s'appliquer a divers procedes etages a contre-courant. Elle consiste a reduire le modele de l'unite en agregeant les etages, puis a appliquer a ce modele reduit, non-lineaire, la technique de rejet de perturbations. La loi de commande s'obtient en resolvant une partie des equations modelisant le regime permanent de l'unite. Ceci nous conduit a poser le probleme du rejet statique de perturbations constantes. Par application de la technique d'elimination, nous donnons, pour les systemes lineaires, des conditions necessaires d'existence d'une loi de commande rejetant statiquement les perturbations. En restreignant le cadre de l'etude, nous donnons des conditions suffisantes. Ces dernieres sont generalisees a des systemes non-lineaires. Ensuite, nous proposons un modele dynamique de cascades de melangeurs-decanteurs. A l'aide de ce modele, nous testons, en simulation, la robustesse des lois de commande presentees precedemment. Nous presentons egalement deux methodes simples destinees a reduire le nombre de mesures necessaires. Ce type de loi de commande a ete mis en oeuvre sur une cascade binaire industrielle. Nous presentons quelques resultats releves sur cette cascade lorsque la commande etait bouclee
Knowledge communication in rate.ee, a web picture-rating community (2008)

This study analyses the knowledge communication processes in the rate.ee web portal in the contexts of knowledge communication and cultural communication. The primary domains where the members of rate.ee participate in knowledge communication are technical and social communication skills, cultural knowledge (like language, norms, values) and specific domains of interest. The users are highly motivated not only to exchange knowledge, but mainly to promote themselves, develop relations with others, develop social networks and design their identities. The knowledge communication processes in such a situation are more complex and less conventional than in task-oriented groups. In the case of this large social community, the communicators and their background, the cultural reality and the technical possibilities of the environment may play an even more important role than the knowledge itself.
Molecular-Oriented Photoalignment Layer for Liquid Crystals (2007)

In this letter, we describe the fabrication of a durable photoalignment layer for liquid crystals (LC) with high azimuthal anchoring and controllability of the tilt angle. A film is irradiated using linearly polarized ultraviolet (LPUV) light followed by annealing which induces the molecular orientation of the photoalignment layer. The nematic LC was aligned parallel to the electric vector of the LPUV light, and the alignment layer showed high thermal stability of the orientational characteristics up to 250 °C.
Development of Neuropathy in Patients With Myeloma Treated With Thalidomide: Patterns of Occurrence and the Role of Electrophysiologic Monitoring (2006)

The majority of patients will develop peripheral neuropathy given sufficient length of treatment with thalidomide. To minimize the risk of neurotoxicity, therapy should be limited to less than 6 months. Electrophysiologic monitoring provides no clear benefit versus careful clinical evaluation for the development of clinically significant neuropathy.
1C31 Study on 2-D Ultrasonic Visualization Technique for Architecture of Cancellous Bone (2001)

To establish the diagnosis of osteoporosis from the mechanical integrity viewpoint, not only bone mineral density (BMD) but also in vivo architecture of bone is essentially needed. A new visualization technique of the trabecular bone is presented. We analyzed numerically the A-mode signals from the transducer for medical use to distinguish whether bone substance or bone marrow. This is based on the damping curve and the threshold line as bone substance. The technique allowed visualizing the architecture to the depth about 10 mm from the bone surface. We demonstrated the validity of this technique using bovine cancellous bone and a ceramic specimen with spongy architecture.
A Perfect Storm? Reimagining Work in the Era of the End of the Job (2014)

Trends of independent workers, an economy of increasingly automated processes and an ethos of the peer‐to‐peer “sharing economy” are all coming together to transform work and employment as we know them. Emerging forms of “open” and “crowd” work are particularly keen sites for investigating how the structures and experiences of work, employment and organizations are changing. Drawing on research and design of work in organizational contexts, this paper explores how experiences with open and crowd work systems serve as sites of workplace cultural re‐imagining. A marketplace, a crowdwork system and a crowdfunding experiment, all implemented within IBM, are examined as instances of new workplace configurations.
The Role of Lateral Extra-articular Tenodesis in Primary Anterior Cruciate Ligament Reconstruction: A Systematic Review With Meta-analysis and Best-Evidence Synthesis (2017)

In primary ACLR, no evidence is available showing additional benefit of LEAT in reducing the postoperative pivot shift in early reconstructions (≤12 months); however, LEAT may have a role in delayed ACLR. Strong evidence exists that a combined ACLR and LEAT reduces lateral femoral translation, but there is insufficient evidence to identify any benefit for other clinical outcomes.
Redox‐Switchable Calix[6]arene‐Based Isomeric Rotaxanes (2018)

Operating molecular machines are based on switchable systems whose components can be set in motion in a controllable fashion. The presence of nonsymmetrical elements is a mandatory requirement to obtain and demonstrate the unidirectionality of motion. Calixarene-based macrocycles have proved to be very efficient hosts in the design of oriented rotaxanes and of pseudorotaxanes with strict control over the direction of complexation. A series of two-station rotaxanes based on bipyridinium-ammonium axles was synthesized and characterized. A recently reported supramolecularly assisted strategy for the synthesis of different orientational isomers was exploited, and the ammonium unit was identified as a proper secondary station for the calixarene. Displacement of the macrocycle was triggered by electrochemical reduction of the bipyridinium primary station, and it was shown that the shuttling is influenced both by the length of the chain of the axle component and by the position of the secondary station with respect to the calixarene rims.
Dental Benefits of Limited Exposure to Fluoridated Water in Childhood (1986)

The effect of limited exposure to fluoridated water in childhood is of potential importance in highly-mobile modern society, but the subject has not been well-studied. This longitudinal study assessed caries experience and S. mutans proportions from fissure plaque in school-children who lived for at least the three years of the study in a non-fluoridated community (0.2 mg/L). Residence histories permitted division of the cohort into those who had lived all their lives in non-fluoridated communities, and those who had lived for some time previously in a fluoridated community. The children were aged 6-7 years at the beginning of the three-year study. Children with previous residence in the fluoridated communities developed 26.8% less caries in their permanent teeth during the study than did the children who had lived in non-fluoridated communities all their lives (p = 0.04), and had 29.8% less caries after three years (p = 0.02). Differences between the groups in S. mutans proportions from fissure plaque, sampled at six-monthly intervals throughout the study, could not be demonstrated. The dental benefits observed could not be attributed to socio-economic differences between the groups. Despite evidence that the benefits of limited ingestion of fluoridated water are topical in nature, the fact that many of the affected teeth in this study were unerupted at the time of the fluoride exposure means that pre-eruptive benefits cannot be ruled out.
Ex vivo conditioning of peripheral blood mononuclear cells of diabetic patients promotes vasculogenic wound healing (2021)

The quality and quantity of endothelial progenitor cells (EPCs) are impaired in patients with diabetes mellitus patients, leading to reduced tissue repair during autologous EPC therapy. This study aimed to address the limitations of the previously described serum-free Quantity and Quality Control Culture System (QQc) using CD34+ cells by investigating the therapeutic potential of a novel mononuclear cell (MNC)-QQ. MNCs were isolated from 50 mL of peripheral blood of patients with diabetes mellitus and healthy volunteers (n = 13 each) and subjected to QQc for 7 days in serum-free expansion media with VEGF, Flt-3 ligand, TPO, IL-6, and SCF. The vascular regeneration capability of MNC-QQ cells pre- or post-QQc was evaluated with an EPC colony-forming assay, FACS, EPC culture, tube formation assay, and quantitative real time PCR. For in vivo assessment, 1 × 10<sup>4</sup> pre- and post-MNC-QQc cells from diabetic donors were injected into a murine wound-healing model using Balb/c nude mice. The percentage of wound closure and angio-vasculogenesis was then assessed. This study revealed vasculogenic, anti-inflammatory, and wound-healing effects of MNC-QQ therapy in both in vitro and in vivo models. This system addresses the low efficiency and efficacy of the current naïve MNC therapy for wound-healing in diabetic patients. As this technique requires a simple blood draw, isolation, and peripheral blood MNC suspension culture for only a week, it can be used as a simple and effective outpatient-based vascular and regenerative therapy for patients with diabetes mellitus.
The synthesis and evaluation of radioiodinated 14-(iodophenyl)-3-(R,S)methyltetradecanoic acid (1985)

Radiohalogenated fatty acids (FA) labelled with gamma-emitting isotopes have a potentially important application in studies of impaired myocardial perfusion and metabolism. Evaluation of straight-chain fatty acids radiolabelled in different positions on the FA chain has been reported by many groups. In this paper we extended our recent studies using the betamethyl branched-chain fatty acid. The synthesis, labelling and preliminary evaluation of 131I- and 123I-14-(iodophenyl)-3-(R,S)methyltetradecanoic acid (I-PBMTA) are reported. This radiolabel concentrates in the mouse myocardium with 16% injected dose g-1 and 11% injected dose g-1 at 15 and 30 min, respectively. The images of the canine heart postinjection indicate a high myocardial extraction of the label with activity retained over an hour. The rate of washout of the activity from the heart was very low. This analogue is a potential agent for myocardial imaging studies.
Growth of one-dimensional Si/SiGe heterostructures by thermal CVD (2008)

The first results on a simple new process for the direct fabrication of one-dimensional superlattices using common CVD chambers are presented. The experiments were carried out in a 200 mm industrial Centura reactor (Applied Materials). Low dimensionality and superlattices allow a significant increase in the figure of merit of thermoelectrics by controlling the transport of phonons and electrons. The monocrystalline nanowires produced according to this process are both one-dimensional and present heterostructures, with very thin layers (40 nm) of Si and SiGe. Concentrations up to 30 at.% Ge were obtained in the SiGe parts. Complementary techniques including transmission electronic microscopy (TEM), selected area electron diffraction (SAED), energy dispersive x-ray spectroscopy (EDS), scanning transmission electron microscopy (STEM) in bright field and high angle annular dark field (HAADF STEM), and energy-filtered transmission electron microscopy (EF-TEM) were used to characterize the nanoheterostructures.
An Experimental Study of the Delayed Mixing Stratified Charge Engine Concept (1977)

<div class="htmlview paragraph">Preliminary computer studies indicated that the delayed mixing stratified charge engine concept might produce low emissions of nitrogen oxide and still provide reasonable efficiency and power. In the delayed mixing stratified charge engine concept a fuel-rich region is burned followed by air being mixed into the rich products. Nitrogen oxide formation was initially limited in the rich product mixtures because of the lack of oxygen and after mixing by the relatively low temperatures due to charge expansion.</div> <div class="htmlview paragraph">A single cylinder engine was used to simulate the delayed mixing stratified charge combustion process. A rich charge was drawn into the engine through the carburetor. Combustion was initiated with a spark; later air was injected to complete the combustion process.</div> <div class="htmlview paragraph">The results showed that emissions could be controlled by the delayed mixing combustion process. The engine specific power was also at reasonable levels. However, the engine efficiency was low.</div>
Effects of macroalgal species identity and richness on primary production in benthic marine communities (2005)

Plant biodiversity can enhance primary production in terrestrial ecosystems, but biodiversity effects are largely unstudied in the ocean. We conducted a series of field and mesocosm experiments to measure the relative effects of macroalgal identity and richness on primary productivity (net photosynthetic rate) and biomass accumulation in hard substratum subtidal communities in North Carolina, USA. Algal identity consistently and strongly affected production; species richness effects, although often significent, were subtle. Partitioning of the net biodiversity effect indicated that complementarity effects were always positive and species were usually more productive in mixtures than in monoculture. Surprisingly, slow growing species performed relatively better in the most diverse treatments than the most productive species, thus selection effects were consistently negative. Our results suggest that several basic mechanisms underlying terrestrial plant biodiversity effects also operate in algal-based marine ecosystems, and thus may be general.
Zyndroid: An Android platform for software/hardware coprocessing (2014)

High performance is required of many Android systems because embedded systems written for this operating system are used in several fields and rely on increasingly complicated processing. To accommodate this, we present a software/hardware (SW/HW) coprocessing platform implemented on a programmable system-on-a-chip (Xilinx Inc.: Zynq). This platform provides a unified architecture, extended OS kernel, application framework, and application distribution model to simplify the development and use of Android SW/HW coprocessing applications.
A framework for interprocedural optimization in the presence of dynamic class loading (2000)

Dynamic class loading during program execution in the Java Programming Language is an impediment for generating code that is as efficient as code generated using static whole-program analysis and optimization. Whole-program analysis and optimization is possible for languages, such as C++, that do not allow new classes and/or methods to be loaded during program execution. One solution for performing whole-program analysis and avoiding incorrect execution after a new class is loaded is to invalidate and recompile affected methods. Runtime invalidation and recompilation mechanisms can be expensive in both space and time, and, therefore, generally restrict optimization. To address these drawbacks, we propose a new framework, called the extant analysis framework , for interprocedural optimization of programs that support dynamic class (or method)loading. Given a set of classes comprising the closed world , we perform an offline static analysis which partitions references into two categories:(1) unconditionally extant references which point only to objects whose runtime type is guaranteed to be in the closed world; and (2) conditionally extant references which point to objects whose runtime type is not guaranteed to be in the closed world. Optimizations solely dependent on the first categorycan be statically performed, and are guaranteed to be correct even with any future class/method loading. Optimizations dependent on the second category are guarded by dynamic tests, called extant safety tests , for correct execution behavior.We describe the properties for extant safety tests, and provide algorithms for their generation and placement.
UsingMCMCF to Solve Multicommodity Flow Problems (1998)

The program’s execution can be altered using command-line flags. Some of these flags include: -E epsilon overrides the desired program accuracy value specified in the input. -L minimumindicates a lower bound on , i.e., the multiple of the arc capacities needed to satisfy the the demands. The program terminates when is within a factor of the specified value and the costs are within the same factor of the minimum possible costs. For the minimum-cost multicommodity flow problem, the default is . That is, stop when the flow fits within a network using at most times arc capacity (and has small enough cost). -l frequency indicates the number of iterations (as a multiple of the number of commodities) that should occur between calculation of the lower bound. The default value is 3. -t multiple helps the program find an initial solution. By default, the program attempts to find an initial solution by individually routing each commodity through the network with capacities as specified in the input. Using the flag, causes the program to trying routing the commodities through a network with capacities multiplied by the specified floating point number. If the problem can be solved with , this flag should not be necessary.
Groundwater Protection Program Science and Technology Summary Description (2002)

The Hanford Site Groundwater Protection Program, formerly the Groundwater/Vadose Zone Integration Project, was established in 1997 to develop the integrated approach, technical capability, and scientific information needed to perform site-wide assessments of the potential effects of Hanford Site soil and groundwater contaminants on people and the ecology. To complete this mission, gaps in scientific understanding and technologies were identified, and research to close those gaps was initiated.
