IMAGINED GEOGRAPHIES AND SEXUALITY POLITICS (2005)

The contributors to this volume, and to the wider study of sexualities, move quite freely between histories and geographies of sex and sexuality on the one hand, and literary and cultural representations on the other. Some contributors concentrate on the former, others on the latter. In their studies of non-metropolitan America, for example, Angelia Wilson (Chapter 11) concentrates on experiences, William Spurlin (Chapter 10) on representations. More generally, writers on this subject display a tendency to privilege one or the other. Foucault has inspired many to privilege what may be called discursive constructions of sexuality-to treat literary representations of sexuality as if they mapped directly onto bodies and identities, in other words as if they were sexualities. Historian Michael Mason argues, conversely, that sexualityencompassing forms of activity, demeanour, professed belief, private belief and more —is not reducible to discourse (Mason 1995:40, 172-3). Other empirically minded historians and geographers point to differences between image and ‘reality’, with regards to sexualities and sexual spaces (e.g. Davies 1996). If image is not the same as ‘reality’ and neither is privileged, there follows the question of how the two spheres co-exist and interact. This means tracing an interplay between what one geographer has called metaphorical and material spaces of sexuality (Brown 1996). In this chapter I explore this kind of interplay, specifically between imagined geographies and concrete sexuality politics.
Automation of the bird shoulder joint deboning (2007)

Poultry deboning processing is one of the largest employers of people in the United States. It involves mainly manual processes with only limited use of fixed automation. The main difficulty in this task is the unstructured nature of the task due to the natural variability of birds’ size and deformable bodies. To increase product safety and quality, the industry is looking to robotics to help solve these problems. This research has focused on automating cutting of bird front halves. The anatomic structure of the chicken shoulder joint was studied first. Thus the cutting locations on chicken front halves were identified. In conjunction with force control robotics, a 3-DOF device with the capability for size adaptation and deformation compensation was proposed and the cutting trajectory was simulated. The results of the dynamic simulation verified that the desired trajectory can be followed and the response time for bone detection can be satisfied. A functional prototype of this device has been built and is currently under evaluation.
A specific amino acid context in EGFR and HER2 phosphorylation sites enables selective binding to the active site of Src homology phosphatase 2 (SHP2) (2020)

The Src homology phosphatase 2 (SHP2) is a cytoplasmic enzyme that mediates signaling induced by multiple receptor tyrosine kinases, including signaling by the epidermal growth factor receptor (EGFR) family (EGFR1-4 or the human homologs HER1-4). In EGFR (HER1) and EGFR2 (HER2) signaling, SHP2 increases the half-life of activated Ras by blocking recruitment of Ras GTPase-activating protein (RasGAP) to the plasma membrane through dephosphorylation of docking sites on the receptors. However, it is unclear how SHP2 selectively recognizes RasGAP-binding sites on EGFR and HER2. In this report, we show that SHP2-targeted pTyr residues exist in a specific amino acid context that allows selective binding. More specifically, we show that acidic residues N-terminal to the substrate pTyr in EGFR and HER2 mediate specific binding by the SHP2 active site, leading to blockade of RasGAP binding and optimal signaling by the two receptors. Molecular modeling studies revealed that a peptide derived from the region of pTyr<sup>992</sup>-EGFR packs well and makes stronger interactions with the SHP2 active site than with the SHP1 active site, suggesting a built-in mechanism that enables selective substrate recognition by SHP2. A phosphorylated form of this peptide inhibits SHP2 activity <i>in vitro</i> and EGFR and HER2 signaling in cells, suggesting inhibition of SHP2 protein tyrosine phosphatase activity by this peptide. Although we do not expect this peptide to be a strong inhibitor by itself, we foresee that the insights into SHP2 selectivity described here will be useful in future development of active-site small molecule-based inhibitors.
The mudslide effect (2001)

A novel range-dependent propagation effect occurs when a source is placed on the seafloor in shallow water with a downward refracting sound speed profile, and sound waves propagate down a slope into deep water. Small grazing-angle sound waves slide along the bottom downward and outward from the source until they reach the depth of the sound channel axis in deep water. They then detach from the sloping bottom and continue to propagate outward near the sound channel axis. This ‘‘mudslide’’ effect is one of a few robust and predictable acoustic propagation effects that occurs in range-dependent ocean environments. Consequently, a bottom mounted source in shallow water can inject a significant amount of energy into the axis of the deep ocean sound channel that propagates to very long ranges. Numerical simulations with a full-wave range-dependent acoustic model show that the Kaneohe experiment had the appropriate source, bathymetry, and sound speed profiles that allowed this effect to operate efficiently. This supports the interpretation that some of the near-axial acoustic signals, received near the coast of California from the Kaneohe source on Oahu, Hawaii, were injected into the sound channel of the deep Pacific Ocean by this mechanism.

Vital Exhaustion and Retinal Microvascular Changes in Cardiovascular Disease: Atherosclerosis Risk in Communities Study (2020)

Negative psychological factors, such as depression, have been implicated in the development of cardiovascular disease. Whether this link is mediated by macrovascular or microvascular disease is unknown. This study aimed to determine whether vital exhaustion, a measure of negative emotion, is associated with microvascular changes in the retina.
Dynamic virtual network reconfiguration over SDN orchestrated multi-technology optical transport domains (2015)

Application-based Network Operations consists of existing components offering an application-driven network management. We validate its applicability to multi-tenant networks in multi-technology optical domains based on congestion detection and failure recovery by demonstrating fast reconfiguration, while keeping the upper layer unaware.
Femtoscopy with identified charged pions in proton-lead collisions at sNN=5.02 TeV with ATLAS (2017)

Bose-Einstein correlations between identified charged pions are measured for p+Pb collisions at s NN = 5.02 TeV using data recorded by the ATLAS detector at the CERN Large Hadron Collider corresponding to a total integrated luminosity of 28 nb -1 . Pions are identified using ionization energy loss measured in the pixel detector. Two-particle correlation functions and the extracted source radii are presented as a function of collision centrality as well as the average transverse momentum (k T ) and rapidity (y ) of the pair. Pairs are selected with a rapidity -2 < y < 1 and with an average transverse momentum 0.1 < k T < 0.8 GeV. The effect of jet fragmentation on the two-particle correlation function is studied, and a method using opposite-charge pair data to constrain its contributions to the measured correlations is described. The measured source sizes are substantially larger in more central collisions and are observed to decrease with increasing pair k T . A correlation of the radii with the local charged-particle density is demonstrated. The scaling of the extracted radii with the mean number of participating nucleons is also used to compare a selection of initial-geometry models. The cross term R ol is measured as a function of rapidity, and a nonzero value is observed with 5.1 combined significance for -1 < y < 1 in the most central events.
P4Pi (2021)

High level, network programming languages, like P4, enable students to gain hands-on experience in the structure of a switch or router. Students can implement the packet processing pipeline themselves, without prior knowledge of circuit design. However, when choosing a P4 programmable target for use in the classroom, instructors face a lack of options. On the one hand, software solutions, such as the behavioral model (BMv2) switch, are overly simplified and offer low performance. On the other hand, existing hardware solutions are closed source and expensive. In this paper, we present P4Pi, a new, low-cost, open-source hardware platform intended for networking education. P4Pi allows students to design and deploy P4-based network devices using the Raspberry Pi board, which has a price tag of less than many academic textbooks. We describe the high-level design of the P4Pi platform, offer some suggestions for how P4Pi could be used in the classroom, and present some additional use-cases for applications and functionality that could be developed using P4Pi.
cis-Clerodane-Type Furanoditerpenoids from Tinospora crispa (2010)

Phytochemical and cytotoxicity investigations on organic solvent extracts of the aerial parts of Tinospora crispa have led to the isolation of 15 cis-clerodane-type furanoditerpenoids. Of these, nine compounds (1-9) were found to be new. Spectroscopic assignments of a previously reported compound, borapetoside A (13), were revised on the basis of HMQC and HMBC correlations. No discernible activity was observed when compounds 10-13 were subjected to evaluation in cytotoxicity assays against human prostate cancer (PC-3) and the normal mouse fibroblast (3T3) cell lines.
Transferring principles of solid-state and Laplace NMR to the field of in vivo brain MRI (2020)

Magnetic resonance imaging (MRI) is the primary method for noninvasive investigations of the human brain in health, disease, and development but yields data that are difficult to interpret whenever the millimeter-scale voxels contain multiple microscopic tissue environments with different chemical and structural properties. We propose a novel MRI framework to quantify the microscopic heterogeneity of the living human brain as spatially resolved five-dimensional relaxation-diffusion distributions by augmenting a conventional diffusion-weighted imaging sequence with signal encoding principles from multidimensional solid-state nuclear magnetic resonance (NMR) spectroscopy, relaxation-diffusion correlation methods from Laplace NMR of porous media, and Monte Carlo data inversion. The high dimensionality of the distribution space allows resolution of multiple microscopic environments within each heterogeneous voxel as well as their individual characterization with novel statistical measures that combine the chemical sensitivity of the relaxation rates with the link between microstructure and the anisotropic diffusivity of tissue water. The proposed framework is demonstrated on a healthy volunteer using both exhaustive and clinically viable acquisition protocols.
Taming internal dynamics by mismatched and H/sub /spl infin//-optimized state observer (2000)

The feedback linearization control scheme is simple but quite effective for control of a single-input single-output (SISO) linear parameter-varying (LPV) plant. When the relative degree of the plant is less than its order, the feedback linearization control scheme generates the internal dynamics, which may or may not be stable. The paper presents the design methodology of a state observer that not only provides the feedback linearization controller with good estimation of state variables of the plant, but also stabilizes the overall closed-loop system. We propose to make the choice of system matrices of the state observer completely open in order to search for such an observer structure. Two application examples, including application to steering control for lateral motion of heavy-duty vehicles, are presented to illustrate how the proposed mismatched observer stabilizes the closed-loop system.

Properties of High Fluidity Concrete with Combination of Fine Powder of Slowly Cooled Blast Furnace Slag and Granulated Blast Furnace Slag (2007)

The properties of high fluidity concrete with a combination of the fine powder of slowly cooled blast furnace slag and granulated blast furnace slag were examined. The change of slump flow value with time decreased when a specified ratio or more of slowly cooled blast furnace slag was used. The concrete with various levels of compressive strength can be prepared by changing the mixing ratio of these powders. It has been clarified that close relations exist between adiabatic temperature rise and the unit weight of binder, as well as between autogenous shrinkage and water binder ratio, and that mix proportion design suited to required performance is possible. By the use of this high fluidity concrete, it is possible to suppress both CO2 emission and limestone consumption per unit of concrete, which suggests that this concrete is useful from the viewpoint of reduction in environmental burden.
A Unique, Mach 6 Enthalpy, Non-Vitiated Facility for Hypersonic Aerodynamics Research (2011)

A new facility has been built at the University of Florida (UF) with unique capabilities for hypersonic research. It was designed specifically for the UF by experts from the Central Institute for Aviation Motors (CIAM) in Moscow, Russia based on the facility used at that institution. The device, described below in detail, is a non-vitiated, continuous operation high-enthalpy facility with two major components: (i) an electrically operated, first stage heater with maximum temperatures of 1300K (1880F) and, (ii) a second, water injection/high-enthalpy heating stage with a continuous, maximum operating temperature of 1800K (2780F). Hence, Mach 6.5 flight enthalpy will be simulated. Additionally, the facility has a response of 5K/s which allows thermal transients, hence simulation of trajectories.
Hybridization in Question Answering Systems (2003)

Question answering systems can benefit from the incorporation of a broad range of technologies, including natural language processing, machine learning, information retrieval, knowledge representation, and automated reasoning. We have designed an architecture that identifies the essential roles of components in a question answering system. This architecture greatly facilitates experimentation by enabling comparisons between different choices for filling the component roles, and also provides a framework for exploring hybridization of techniques ‐ that is, combining different approaches to question answering. We present results from an initial experiment that illustrate substantial performance improvement by combining statistical and linguistic approaches to question answering. We also present preliminary and encouraging results involving the incorporation of a large knowledge base.
The Surface Chemistry of Au Colloids and Their Interactions with Functional Amino Acids (2004)

The work reported here describes interactions between nanoscale Au colloids and two main types of organic functional groups, viz., alkanethiols and amino acids. The surface chemistry of particulate Au is dominated by electrodynamic factors related to its (negative) surface charge. Generalized multiparticle Mie calculations were used to model the optical absorption characteristics of Au particles, existing either singly or in varying degrees of aggregation. Experiments with standard (monodisperse) Au colloids confirm the theoretical prediction of a new peak appearing at longer wavelength that intensifies and shifts further from the original peak with increasing particle size, increasing aggregate size, or shorter interparticle spacing. Control of aggregation degree in alkanethiols is achieved by judicious selection of terminal group composition (single- or double-ended), alkyl chain length, and the presence of pH sensitive groups such as carboxylates. In amino acids, the reactivity of the α-amine (adjacent to −COOH) is found to be pH-dependent. Linking via the α-amine is activated at low pH but suppressed at intermediate and high pH due to electrostatic repulsive forces between the Au surface and the charged carboxylate group or even the (formally neutral) polar carbonyl group in amides. However, dibasic amino acids can still be used to cross-link Au colloids at high pH. The pH insensitive (remote) amine binds amino acids to each particle, leaving protruding pairs of α-amines that can be bridged by a symmetrical linker molecule like glutaraldehyde (via its electrophilic centers). This offers a new way to organize Au nanoparticles into extended architectures and functional materials over a wide range of pH. The potential of Au colloids to recognize and determine dibasic amino acids based on optical absorption changes is briefly assessed. A higher detection limit for cysteine (1.2 μg/mL) was found for larger (40 nm) Au particles.
Selective-area growth of single-crystal wurtzite GaN nanorods on SiOx/Si(001) substrates by reactive magnetron sputter epitaxy exhibiting single-mode lasing (2017)

Selective-area growth (SAG) of single-crystal wurtzite GaN nanorods (NRs) directly onto Si(001) substrates with un-etched native SiO<sub>x</sub> amorphous layer, assisted by a patterning TiN<sub>x</sub> mask fabricated by nanosphere lithography (NSL), has been realized by reactive magnetron sputter epitaxy (MSE). The GaN NRs were grown vertically to the substrate surface with the growth direction along c-axis in the well-defined nano-opening areas. A 5-step structural and morphological evolution of the SAG NRs observed at different sputtering times depicts a comprehensive growth model, listed in sequence as: formation of a polycrystalline wetting layer, predominating c-axis oriented nucleation, coarsening and coalescence of multi-islands, single NR evolution, and finally quasi-equilibrium crystal shape formation. Room-temperature cathodoluminescence spectroscopy shows a strong GaN bandedge emission with a uniform luminescence across the NRs, indicating that the SAG NRs are grown with high quality and purity. In addition, single-longitudinal-mode lasing, attributed to well-faceted NR geometry forming a Fabry-Pérot cavity, was achieved by optical pumping, paving a way for fabricating high-performance laser optoelectronics using MSE.
Effect of retinoic acid on morphological changes of human pancreatic cancer cells on collagen gels: a possible association with the metastatic potentials. (1998)

Pancreatic carcinoma is an invasive and metastasizing type of malignancy. We established six pancreatic cancer cell lines from human pancreatic carcinomas, three highly metastatic lines (KP-1NL, KP-4, and SUIT-2) and three minimally metastatic lines (KP-2, KP-3, and BxPC-3). The three highly metastatic cell lines grew in a fibroblastoid pattern on collagen gels, whereas the three minimally metastatic cell lines grew in an epithelioid pattern under similar conditions. Western blot and Northern blot analyses indicated much higher levels of E-cadherin in the three minimally metastatic cell lines relative to the three highly metastatic cell lines. When the effect of all-trans-retinoic acid on the growth patterns of the three highly metastatic lines was examined, we observed a dramatic change from fibroblastoid to epithelioid growth in SUIT-2 cells. Although all six cell lines had comparable levels of retinoic acid receptor-gamma, retinoic acid receptor-beta was expressed only in SUIT-2 cells. Treating SUIT-2 cells with retinoic acid also induced the upregulation of E-cadherin expression. When SUIT-2 cells were treated with retinoic acid receptor-specific agonists, 13-cis-retinoic acid and Am555S, a morphological change from fibroblastoid to epithelioid growth was induced. Retinoic acid receptor-specific antagonists, LE135 and LE540, inhibited retinoic acid-induced change of the growth patterns. The effect of retinoic acid and its derivatives on the growth pattern was discussed in a possible association with their antimetastatic activities of pancreatic cancer.
A Decoupling Method for Two PIFAs by Using Bridged Two Parasitic Elements (2019)

In this study, we investigate a simple method to reduce the mutual coupling between two planar inverted-F antennas (PIFAs). The method shows that by using a parasitic element (PE) which is linked with a bridge line (BL) and loaded upon the PIFAs, good impedance matching and low mutual coupling around resonant frequency can be obtained without the necessity of adjusting dimensions of the PIFAs. This method is also expected to be an effective method to reduce mutual coupling of the larger PIFA arrays in future works.
