<title>Advancements in KC-135 microgravity testing of an autonomous satellite docking system</title> (2004)

During the development of an autonomous spacecraft docking mechanism, one of the primary areas of interest in the way the mechanism will behave in a micro-gravity environment. This issue is of particular interest when a flexible soft-dock cable is used to make initial capture, because ground-based testing does not adequately represent the environmental conditions that will be seen on orbit. To this end, Michigan Aerospace Corporation has recently conducted flight tests of its prototype autonomous satellite docking system in a micro-gravity environment on the KC-135 in conjunction with the Air Force Research Laboratory Space Vehicles Directorate and Microcosm, Inc. Though the first flight was primarily for the purpose of testing the core operating principles of the docking mechanism, several lessons were learned that will be applied toward developing a second, more advanced prototype and experimental setup intended for a second series of flights on the KC-135. Areas of improvement for the new flight test will be in the physical operation of the experimental apparatus and the data collection methods used. The use of redundant sensors as a means of eliminating noise will be explored, as will the merits of using a combination of coarse and fine sensors to collect data over a broader measurement range.

<title>Free-electron laser nonlinear spectroscopy of doubly resonant (5.5-3.0um and 4.1-2.1 um)InGaAs/AlGaAs asymmetric quantum wells</title> (1994)

Conduction band intersubband absorption and second harmonic generation (SHG) are demonstrated in doubly resonant asymmetric step high indium content quantum wells (QW) grown on a GaAs substrate. Intersubband absorption peaks at 5.51 micrometers and 3.05 micrometers corresponding to the 1 to 2 and 1 to 3 transitions are measured. The susceptibility of SHG from the QW, (Chi) <SUB>QW</SUB><SUP>(2</SUP>), is measured using a free electron laser by interference between the SHG fields generated from the QW and the GaAs substrate. A large asymmetry in the SHG power with rotation angle of the sample arising from (Chi) <SUB>QW</SUB><SUP>(2</SUP>) is observed. The magnitude and phase of (Chi) <SUB>QW</SUB><SUP>(2</SUP>) is measured in the 4.6 - 6.3 micrometers pump wavelength range. (Chi) <SUB>QW</SUB><SUP>(2</SUP>) is of maximum amplitude at 6.0 micrometers with a value of 145 +/- 20 nm/V. A change in the sign of the phase of (Chi) <SUB>QW</SUB><SUP>(2</SUP>) within the SHG resonance is demonstrated for the first time. Agreement of both the linear and nonlinear properties to a simple model assuming Lorentzian linewidths is discussed. SHG of 2.0 micrometers light is also demonstrated in coupled In<SUB>0.60</SUB>Ga<SUB>0.40</SUB>As/AlAs quantum wells.
A Realization of Motion Copying System Based on Multilateral Control (2008)

This paper proposes a motion copying system in order to reproduce motion of human operators. The motion copying system consists of both motion saving system and motion loading system based on multilateral controller. The motion saving system is realized by master systems and a slave system. The motion saving system saves motion of a slave system when human operator moves the master systems. At the same time, identity ratio is introduced to decouple the masters motions. The identity ratio of each master system is calculated by force of all master systems, and are saved to memory. On the contrary, real-world master systems and a virtual-world slave system realize the motion loading system. The motion loading system reproduces the motion using saved motion data and value of the identity ratio. The paper confirms that the motion saving system and motion loading system based on multilateral controller is generalized. The reproduced position and force correspond to the saved ones by the proposed method.
A Research on Improving the Availability of Hybrid Energy Power System (2018)

This paper is designed for the site of hybrid energy power system of solar and diesel generator. Referring to the site survey information, we propose an optimized configuration method which includes solar photovoltaic panel capacity, battery capacity and diesel generator capacity for the hybrid power system. The optimized configuration method reduce the initial investment of the investors. After analysis of historical data of a large number of hybrid sites, we also propose an intelligent control strategy to achieve the goal of zero discarding solar energy to maximize the use of solar energy, and reduce the running time of diesel generator. And then the maintenance costs of the operator are reduced.
Photo-induced tautomerisation of methyltrioxorhenium(vii): the intermediate in olefin metathesis? (2000)

Matrix-isolated [CH3ReO3] tautomerises to [H2CRe(O)2OH] under the influence of UV light; the carbene has been characterised in its normal and 2H- and 13C-enriched isotopic forms by its IR spectrum with results well replicated by quantum chemical calculations.
Effects of collimator aspect ratio and deposition temperature on copper sputtered seedlayers (1999)

We have investigated the effects of collimator aspect ratio and deposition temperature of copper seedlayers to improve conformality in aggressive single and dual damascene structures. Collimation filters of various aspect ratios were used to deposit copper seedlayers which were then filled using electrodeposition. It was found that collimators of 1.0 aspect ratio resulted in the best seedlayer conformality, as evidenced by film structure coverage and quality of plating fill. Further, electrical testing using 68 000 via chains also showed the average via resistance to be lowest and the chain opens yield to be highest with the 1.0 aspect ratio condition. Finally, thermal effects on seedlayer conformality were examined by varying the wafer temperature during deposition. It was observed that deposition temperatures of 100 °C and lower resulted in smoother films as compared to seedlayers deposited at 200, 300, or even 400 °C.

On the portability and performance of fully monolithic transformer structures for RF power amplfiers in standard CMOS process (2008)

In this paper, we examine several proposed power combining topologies for RF power amplifiers (PA). These structures are simulated in a generic 45nm CMOS process to allow for comparison of their process portability distinguishing necessary adaptations for reasonable performance. The power combining structures are compared and explored by means of electromagnetic (EM) simulations to help establish an attainable baseline performance using classical transformer structures for fully monolithic combiners with standard CMOS processes.
Shear-Enhanced Dynamic Adhesion of Lactobacillus rhamnosus GG on Intestinal Epithelia: Correlative Effect of Protein Expression and Interface Mechanics (2018)

The oral uptake of probiotic microorganisms as food additives is one widely used strategy to sustain and improve the homeostasis of intestinal microbiota that protect the intestinal epithelia from attack by pathogenic bacteria. Once delivered to the ileum and colon, probiotics must adhere and form colonies on mucus that coats the surface of intestinal epithelial cells. Although an increasing amount of knowledge about the genetic and molecular level mechanisms of probiotics-mucus interactions has been accumulated, little is known about the physicochemical aspects of probiotics-mucus interactions under physiological shear in intestines. In this study, we established well-defined models of intestinal epithelial cell monolayers based on two major constituents of gut epithelia, enterocytes and goblet cells. First, the formation of a polarized cell monolayer sealed by tight junctions was monitored by transepithelial electrical resistance over time. The establishment of tight junctions and secretion of mucus proteins (mucin) was confirmed by immunofluorescence staining. In the next step, we measured the elasticity of cell monolayer surfaces by indentation using particle-assisted atomic force microscopy. The effective elastic modulus of goblet cell-like cells was 30 times smaller compared to that of enterocyte-like cells, which can be attributed to the secretion of a 3 μm thick mucin layer. As probiotics, we used Lactobacillus rhamnosus GG (LGG), which is one of the most widely used strains as food additives. To investigate the dynamic adhesion of LGG to the intestine model surface, we transferred the epithelial cell monolayer into a microfluidic chamber. A distinct difference in dynamic adhesion between two cell types was observed, which could be attributed to the difference in the mucin expression amount. Remarkably, we found that the dynamic LGG adhesion is enhanced by the increase in shear stress, showing a maximum binding efficiency at 0.3 Pa. Finally, we examined the persistence of LGG adhesion by a stepwise increase in the shear stress exerted on adherent LGG, demonstrating that LGG could withstand high shear stress even beyond that of physiological stress. The obtained results present a large potential to quantitatively understand the influence of engineered foods and probiotics on the homeostasis of microbiota on the surface of intestinal epithelia.
Search for vectorlike light-flavor quark partners in proton-proton collisions at s=8  TeV (2018)

A search is presented for heavy vectorlike quarks (VLQs) that couple only to light quarks in protonproton collisions at ffiffi ffi s p 8 TeV at the LHC. The data were collected by the CMS experiment during 2012 and correspond to an integrated luminosity of 19.7 fb -1 . Both single and pair production of VLQs are considered. The single-production search is performed for down-type VLQs (electric charge of magnitude 1=3), while the pair-production search is sensitive to up-type (charge of magnitude 2=3) and down-type VLQs. Final states with at least one muon or one electron are considered. No significant excess over standard model expectations is observed, and lower limits on the mass of VLQs are derived. The lower limits range from 400 to 1800 GeV, depending on the single-production cross section and the VLQ branching fractions B to W, Z, and Higgs bosons. When considering pair production alone, VLQs with masses below 845 GeV are excluded for BW 1.0, and below 685 GeV for BW 0.5, BZ BH 0.25. The results are more stringent than those previously obtained for single and pair production of VLQs coupled to light quarks.
Influence of wall luminance and uniformity on preferred task illuminance (2017)

Literature suggests an influence of the luminance from non-horizontal surfaces in our visual field on our visual and psychological assessments of an office space. These assessments are believed to directly relate to our expressed preferred task illuminances. This paper describes an evaluation in a mock-up office, wherein wall conditions with a non-uniform and a more uniform light distribution of 3 different average luminance levels have been evaluated regarding their effect on users' preferred task illuminance. Each condition is evaluated starting from three different initial desk illuminances. For all test conditions, a wall with a non-uniformly distributed average luminance of 200 cd/m2 lead to significantly lower selected desk illuminances than a uniformly lit wall with the same average luminance level. In all cases, preferred task illuminances set were significantly lower when offering the lowest starting level for dimming of 300 lx. The range of preferred illuminance levels between subjects was also found to be smaller for dimming with the starting level of 300 lx at desk level. The study suggests that when providing users with personal control they will control the total perceived brightness in their visual field, even though they are only directly affecting their task illuminance level. Triggering the selection of lower preferred illuminance levels due to a personal control starting level of 300 lx, will positively influence the energy used for lighting. The smaller range of preferred illuminance levels between subjects at the starting of 300 lx could reduce the risk of lighting preference related conflict between people. However, more research is needed to confirm that these smaller differences are also perceivable by users.
A Multiligand-Based Palladium Catalyst for C-N Cross-Coupling Reactions (2011)

An alternative approach to the ­development of catalysts for C-N cross-coupling reactions is presented. The authors report a palladium catalyst based on two different biaryl-phosphine ligands, RuPhos and BrettPhos. By a ligand exchange reaction, this system takes the form of multiple catalysts, displaying the highest reactivity and substrate scope of all C-N cross-coupling systems which have been reported so far.
Experimental Investigation of Frequency Domain Channel Extrapolation in Massive MIMO Systems for Zero-Feedback FDD (2020)

Estimating downlink (DL) channel state information (CSI) in frequency division duplex (FDD) massive multi-input multi-output (MIMO) systems generally requires downlink pilots and feedback overheads. Accordingly, this paper investigates the feasibility of zero-feedback FDD massive MIMO systems based on channel extrapolation. We use the high-resolution parameter estimation (HRPE), specifically the space-alternating generalized expectation-maximization (SAGE) algorithm, to extrapolate the DL CSI based on the extracted parameters of multipath components in the uplink channel. We apply the HRPE to two different channel models: the vector spatial signature (VSS) model and the direction of arrival (DOA) model. We verify these methods through real-world channel data acquired from channel measurement campaigns with two different types of channel sounders: a) a switched array-based, real-time, time-domain, outdoors setup at 3.5 GHz, and b) a virtual array-based, high-accuracy, frequency-domain, indoors setup at 2.4 and 5-7 GHz. The performance metrics of the extrapolated channels that we evaluate include the mean squared error, beamforming efficiency, and spectral efficiency in multiuser MIMO scenarios. The results show that the HRPE-based channel extrapolation performs best under the simple VSS model, which does not require array calibration, and if the BS is in an open outdoor environment having line-of-sight (LOS) paths to well-separated users.
In-Vehicle Experimental Tests to Evaluate the Performance of Alternator Pulleys (2017)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;Vehicle alternator pulleys with one-way-clutch and vibration attenuation mechanisms have recently been adopted in modern vehicles in order to reduce or mitigate undesirable side effects of torsional vibrations generated by Internal Combustion Engines (ICE) during its normal operation. It is noticeable how excessive vibration can be particularly detrimental to the components of the Front-End Accessory Drive (FEAD) system. Increase of inertia forces due to the use of larger alternators along with the increase in torsional vibration amplitudes of downsized engines added up with lower idling speeds to reduce emissions have set a challenge for proper FEAD functioning and validation. In order to validate potential design solutions, in-vehicle experimental tests are an important approach. How to define an adequate test plan, execute test cycles and post-process bulk experimental data to assure proper assessment of alternator pulley alternatives is a key factor of success. Proper parameter selection and measurement procedure during operating conditions of the vehicle should be carefully stablished. An experimental procedure to evaluate potential vibration attenuation of each alternator pulley technology by checking transverse displacement of the drive belt and transmission error and other FEAD performance based on post-processing of rotational speed data is proposed herein. In addition, selection and development of custom fitted sensors for FEAD evaluation have also been an outcome of the research, due to packaging space constraints and sample rate required to capture the dynamic events during vehicle operation. The results obtained allow a comprehensive functional analysis of different types of alternator pulleys and its impact in overall system performance, defining an in-vehicle experimental method that can be applied to confirm design alternatives during FEAD development and validation phases.&lt;/div&gt;&lt;/div&gt;

Disseminated Human Malignant Melanoma in Congenitally Immune-Deficient (bg/nu/xid) Mice (1991)

Congenitally immune-deficient bg/nu/xid (BNX) mice are severely compromised in their ability to mount T-cell, B-cell, and lymphokine-activated killer (LAK) cell responses. Successful engraftment of BNX mice with human hematopoietic stem cells has been demonstrated recently. We have investigated the potential use of BNX mice for studies relating to the biology and immunotherapy of human malignant melanoma. The intravenous injection of fresh single-cell suspensions of human malignant melanomas into mice resulted in widely disseminated disease. Metastatic spread of human melanoma in BNX mice mimicked that observed in patients: eg, there were numerous tumor nodules identified in the subcutaneous tissues as well as in a variety of visceral organs, including spleen, kidneys, thyroid, adrenals, lungs, heart, and brain. BNX mouse lymph nodes were replaced consistently by human malignant melanoma cells. The presence of human tumor cells in these mice was confirmed by histologic analysis and microcytofluorometry analyses using human melanoma-specific monoclonal antibodies (MAbs). Moreover, human melanoma cells passaged in BNX mice remained lysable in vitro by specifically cytolytic, autologous human tumor-infiltrating lymphocytes (TILs). The capacity of fresh human malignant melanoma to disseminate widely in BNX mice may prove valuable not only for study of the biology of metastatic spread but also for studies of the immunotherapy of human melanoma using melanoma-specific MAbs and chemotherapeutic agents, as well as human TILs and LAK cells with or without retrovirus-mediated gene transfer modification.
Isolated Bone Marrow Manifestation of HIV-Associated Hodgkin Lymphoma (2002)

Human immunodeficiency virus-associated Hodgkin lymphoma frequently involves the bone marrow and is usually recognized at staging after Hodgkin lymphoma diagnosis on a lymph node or other tissue biopsies, but occasionally the marrow involvement is the only apparent manifestation of disease. In the latter setting, diagnosis can be problematic. From a total of 42 patients with newly diagnosed human immunodeficiency virus-associated Hodgkin lymphoma, 22 subjects had positive marrow involvement at diagnosis; 16 of them had additional substantial histological and/or clinical extramedullary Hodgkin lymphoma. In the remaining 6 patients the bone marrow was the only site of disease at diagnosis. In all six cases, bone marrow biopsy revealed obvious lymphomatous involvement. Reed-Sternberg cells were identified both morphologically and immunophenotypically in all cases. Spared marrow tissue consistently showed fibrosis. All patients were males with a median age of 35 years (range, 31-58 years). All presented with fever, blood cytopenias, and severe CD4+ lymphocyte depletion (median, 70 cells/mm(3)). After diagnosis, all staging procedures were negative, and all patients were treated with chemotherapy. Median survival was 4 months (range, 2-118 mo). Longer survival was achieved in the patients who completed chemotherapy regimens; three subjects, however, died shortly before the full completion of chemotherapy, two of them from Hodgkin lymphoma. Isolated bone marrow HIV-associated Hodgkin lymphoma may be an underestimated condition in HIV-infected patients; in those individuals with unexplained fever and blood cytopenias, bone marrow biopsy should be performed with the aim of assessing for Hodgkin lymphoma, even in the absence of nodal and visceral lymphomatous involvement. A rapid diagnosis of isolated bone marrow HIV-associated Hodgkin lymphoma could expedite therapy.
Craft Practices of Live Coding Language Design (2015)

This paper reflects on the development process of two Live Coding languages, Blackwell’s Palimpsest and Aaron’s Sonic Pi, from the perspective of practice-led arts and craft research. Although informed by prior research in education, music, end-user programming and visual languages, these projects do not apply those principles through conventional software engineering processes or HCI techniques. As is often the case with practice-led research, the development process itself provides an opportunity for reflection on the nature of software as a craft – both for live-coding researchers, and for users of the live-coding systems that we create. In reflecting, we relate our own practice to recent perspectives on software as material, and on the role of craft as an element of interaction design research. The process that we have followed to support this analysis could be applied by other developers wishing to engage in similar reflection.
