Kicking, Snapping, and Throwing the Ball in Intercollegiate Robotic Football (2016)

The goal of this project is to improve multiple robots by introducing new designs. The robots that are being improved upon are the kicker, center, and the quarterback from last year’s capstone. The rules are kept as similar to traditional football as possible, except the game is played by 8 robots on the field for each team. Each robot has a size, weight, and power constraint. The current kicker is inconsistent in both distance and direction of kick. The directional inconsistency is primarily due to lack of rigidity in the kicking mechanism, as well as a highly variable football placement on the tee. The kicker performs inconsistently and inadequately in the distance of kick primarily due to the placement and type of the elastic band. The addition of an actual scale-size goal post for extra points and field goals requires a more precise kicking mechanism. The kicker is being totally rebuilt. The chosen design uses elastic bands as the method for storing the mechanical energy used to power the motion of the kicking mechanism. The design uses an 18” leg as the kicking mechanism. Several feet and tee designs are being prototyped and tested to determine the most effective combination that produces the most reliable kick. A reliable kick is defined as how consistent the trajectory of the ball is after the kick. The leg is going to be made of 1” square aluminum 80-20-framing. The frame of the robot is going to be made out of the 8020-framing with walls made of 0.25” HDPE plastic. The center is only going to have the ball delivery system worked on. Currently, it does not have a way to keep the arm from rotating freely unless a rotation command is given. Also, if the ball is not placed correctly in the ball-holding mechanism, the center has a high risk of fumbling the football during the snap. To stop the arm from freely rotating, a solenoid with a rubber braking pad is going to be used to apply a frictional force to the arm. To reduce the error in placing the ball in the ball-holding mechanism, a back-stop is being incorporated to the current ball-holding mechanism. When feasible, stock products will be purchased and used in assembling the robots. Otherwise, the pieces needed for assembly will be fabricated in-house. The metal and plastic will be cut in the shop. Several simple braces will be created in-house to save money. Prototyping for the foot and tee designs is being accomplished with the 3D printer.

Experimental Histoplasmosis in the Beige Mouse (1987)

Mice carrying the beige mutation (bg/bg) on a C57Bl/6 background were challenged with Histoplasma capsulatum. bg/bg mice had higher mortality and higher lung tissue fungal counts in their lungs than either bg/+ or C57Bl/6 mice challenged with equal inocula. Immunologic studies showed that bg/bg mice developed normal delayed-type hypersensitivity (DTH) reactions to histoplasmin, but had deficient NK cell cytotoxic activity against YAC-1 target cells. Studies of macrophage killing of H. capsulatum in vitro showed that T lymphocytes of either bg/+ or bg/bg mice were able to activate fungal killing by bg/+ but not by bg/bg macrophages. These studies, while not excluding a role for the NK cell, suggest that macrophage dysfunction may be critical in the greater susceptibility of the bg/bg mouse and, by extension, that macrophage function is of major importance in host defense against H. capsulatum.
Evidence for different aetiologies of low estradiol response to FSH: age-related accelerated luteinization of follicles or presence of ovarian autoantibodies (2002)

In the absence of ovarian antibodies, low responses are associated with higher age and accelerated luteinization of mature follicles, rather than diminished responsiveness. Ovarian antibody may be an additional tool to predict and individualize treatment regimens in poor responders.
Dynamic tracking for microrobot with active magnetic sensor array (2021)

Accurate position feedback in a wide range is critical for medical microrobotics and robot-assisted examinations, such as colonoscopy, bronchoscopy and capsule endoscopy examination. Among the many modalities of positioning feedback, magnetic tracking is a preferable method due to the unique advantages of free line of sight, free energy storage and untethered connection. However, the field strength of the magnetic source decreases with the third power of the distance, limiting the effectiveness of position feedback at long distances. In order to maintain a consistently high tracking accuracy in a broad area, this paper presents a new dynamic tracking solution by applying a movable sensor array. In this new solution, the tracking accuracy of the magnet is first determined and optimized within a short range. When the target microrobot carrying the magnet exceeds this optimized range, the sensor array is relocated by an external robotic arm to keep the target in the effective tracking range. Moreover, we also propose a multi-point locating algorithm to minimize the varying background noise. Experimental results show that the proposed method increases the range of magnetic tracking and achieves a satisfactory level of tracking accuracy, which demonstrates significant potentials to improve the position feedback of microrobots in medical applications.
Modeling electrode polarization in dielectric spectroscopy: Ion mobility and mobile ion concentration of single-ion polymer electrolytes (2006)

A novel method is presented whereby the parameters quantifying the conductivity of an ionomer can be extracted from the phenomenon of electrode polarization in the dielectric loss and tan delta planes. Mobile ion concentrations and ion mobilities were determined for a poly(ethylene oxide)-based sulfonated ionomer with Li(+), Na(+), and Cs(+) cations. The validity of the model was confirmed by examining the effects of sample thickness and temperature. The Vogel-Fulcher-Tammann (VFT)-type temperature dependence of conductivity was found to arise from the Arrhenius dependence of ion concentration and VFT behavior of mobility. The ion concentration activation energy was found to be 25.2, 23.4, and 22.3+/-0.5 kJmol for ionomers containing Li(+), Na(+), and Cs(+), respectively. The theoretical binding energies were also calculated and found to be approximately 5 kJmol larger than the experimental activation energies, due to stabilization by coordination with polyethylene glycol segments. Surprisingly, the fraction of mobile ions was found to be very small, <0.004% of the cations in the Li(+) ionomer at 20 degrees C.
Ginsenoside Rh2 Induces Human Hepatoma Cell Apoptosisvia Bax/Bak Triggered Cytochrome C Release and Caspase-9/Caspase-8 Activation (2012)

Ginsenoside Rh2 (G-Rh2) has been shown to induce apoptotic cell death in a variety of cancer cells. However, the details of the signal transduction cascade involved in G-Rh2-induced cell death is unclear. In this manuscript we elucidate the molecular mechanism of G-Rh2-induced apoptosis in human hepatoma SK-HEP-1 cells by demonstrating that G-Rh2 causes rapid and dramatic translocation of both Bak and Bax, which subsequently triggers mitochondrial cytochrome c release and consequent caspase activation. Interestingly, siRNA-based gene inactivation of caspase-8 effectively delays caspase-9 activation and apoptosis induced by G-Rh2, indicating that caspase-8 also plays an important role in the G-Rh2-induced apoptosis program. Taken together, our results indicate that G-Rh2 employs a multi pro-apoptotic pathway to execute cancer cell death, suggesting a potential role for G-Rh2 as a powerful chemotherapeutic agent.
The anterior ectoylvian sulcal auditory field in the cat: II. A horseradisha peroxidase study of its thalamic and cortical connections (1990)

The thalamic and cortical projections to acoustically responsive regions of the anterior ectosylvian sulcus were determined by identifying retrogradely labelled cells after physiologically guided iontophoretic injections of horseradish peroxidase. The medial division of the medial geniculate nucleus, the intermediate division of the posterior nuclear group, the principal division of the ventromedial nucleus, and the lateroposterior complex were consistently labelled after these injections, although each animal showed slightly different patterns of labelling. The suprageniculate nucleus and the lateral and medial divisions of the posterior nuclear group were also labelled in most experiments. The cortex of the suprasylvian sulcus was the most consistently and densely labelled cortical region; each experiment showed a slightly different pattern of labelling throughout the suprasylvian sulcus, with an overall tendency for greater labelling in the ventral (lateral) bank of the middle region of the sulcus. Other cortical regions labelled less consistently included the anterior ectosylvian sulcus itself, the insular cortex of the anterior sylvian gyrus, and the posterior rhinal sulcus. In three experiments the contralateral cortex was examined and a small number of labelled cells was located in the anterior ectosylvian and suprasylvian sulci. Input from extralemniscal auditory thalamus is compatible with previously described auditory response properties of anterior ectosylvian sulcus neurons. The results also confirm the presence of input from visual and multimodal regions of thalamus and cortex, and therefore support claims of overlap of modalities within the sulcus. This overlap, as well as input from motor regions, suggests that the anterior ectosylvian sulcal field serves a sensorimotor role.
Serious game for functional rehabilitation (2015)

Conventional musculoskeletal rehabilitation consists of a therapy consultancy, an exercise assignment, and an execution task with or without assistance of the therapist. This classical approach consumes much of the patient's time, money and effort, as well as the medical staff's. Serious games have been devised as an aided tool for clinical and home-based rehabilitation, with patient autonomy in the exercise execution but monitored by the therapist. The aim of this present study was to develop a real-time serious gaming system including a series of locomotion training exercises for musculoskeletal rehabilitation. Kinect sensor was used to capture real-time kinematics during each exercise. Six exercises with different levels of difficulties were designed and created. Several graphical user interfaces were developed for 3D animation and kinematic feedback tracking and visualization. An evaluation campaign with ten healthy subjects was established to assess the developed system. Obtained results showed that our system is robust and user-friendly for motivating the patient during his functional rehabilitation program at his clinic or at home.
Reliable and efficient performance monitoring in linux (2016)

Processor hardware performance counters have recently improved in quality and features, while performance monitoring support in Linux has been significantly revamped with the development of the perf_events subsystem, which contributed in making performance analysis an increasingly common practice among developers. However, no performance analysis is possible without an efficient monitoring interface and reliable hardware counter data. In this paper, we first address a reliability issue in the Performance Monitoring Unit of recent Intel processors with Hyper-Threading enabled. A published erratum causes cross hyper-thread hardware counter corruption and may produce unreliable results. We propose a cache-coherence style protocol which we implement in the Linux kernel to address the issue by introducing cross hyper-thread dynamic event scheduling. Second, we improve event scheduling efficiency by introducing an algorithm which optimally schedules events onto hardware counters consistently. The proposed optimizations do not require any user level changes. They leverage the internal design of the perf_events subsystem and have broader applicability in processors. The improvements have been contributed to the upstream Linux kernel 4.1.
Carpal Tunnel Syndrome and Vitamin B6 (1987)

We reviewed 1075 patients presenting over a 12-year period with symptoms of carpal tunnel syndrome. A total of 994 had a final diagnosis of carpal tunnel syndrome. There were 444 male and 550 female patients with a mean age of 42 years. Three-hundred and ninety-five related symptoms to their job. Surgery was performed in 27 percent of the total diagnosed cases with approximately 97 percent relief of symptoms. Satisfactory alleviation of symptoms was obtained in 14.3 percent of patients treated conservatively prior to 1980, with one or a combination of splinting anti-inflammatory agents, job or activity change, and steroid injections. In 1980, vitamin B6 (pyridoxine) was added as a method of conservative treatment. Satisfactory improvement was obtained in 68 percent of 494 patients treated with a controlled dosage (100 mg b.i.d.). While our findings were not the result of a controlled scientific study, we feel they suggest that regulated use of vitamin B6 may be helpful in treating many cases of carpal tunnel syndrome.
EXTENDED DEFECTS AND PRECIPITATES IN IMPLANTED TiO2 (1981)

TiO2 single crystals implanted at 77 K with heavy ions in the energy range (100 keV-500keV) have been observed using transmission electron microscopy (T.E.M.) and X ray diffraction at glancing incidence. Alkali ions react with oxygen of the lattice in order to form chemical bonds correlated with modification of the charge state of titanium (Ti3+). In this case, T.E.M. observations show thar planar defects ([MATH]01) type are created in the implanted layer. These extended defects are decorated by precipitates which give displacement fringes. The formation of titanate considered after T.E.M. experiments is confirmed by X ray diffraction. On the opposite side, metallic ions of high electronegativity such as Au+ implanted in TiO2 form small metallic clusters. The presence of gold precipitates which have been considered after optical and T.E.M. measurements is confirmed by X ray diffraction analysis. More dislocations and extended defects are observed in addition to planar defects ; they can be due to sputtering effects during implantation.
Residual Fringe Visibility for Enhancing Image Contrast of Numerical Reconstruction in Digital Off-Axis Holography (2020)

We show that background fringe pattern subtraction is a useful technique in removing static noise from off-axis holographic reconstructions and can enhance image contrast in volumetric reconstructions by an order of magnitude.
Parameter Differentiation of Quantum-Mechanical Linear Operators (1963)

Quantum-mechanical linear operators have some real-number parameters in them. The differential coefficients of functions, including eigenvalues and eigenvectors, of such an operator with respect to a parameter are calculable from the differential coefficient of the operator with respect to the parameter. The formulas for this purpose are presented together with their proofs.

Frequency-bin entanglement of narrowband photon pairs (2017)

Summary form only given. The ability to transfer entanglement over large distance is a main requirement for quantum networks. Another fundamental ingredient is the storage of such a quantum state in a quantum memory. To this end a useful resource is a photon pair for which one photon is resonant with the memory while its partner is at a low-loss telecommunication wavelength. We recently presented a photon pair source, compatible with a Pr:YSO solid state memory [1]. The photons have a narrow bandwidth for compatibility with the memory transition. Generating and transmitting qubits based on such photons is not straight forward, as usual implementations as e.g. polarisation qubits suffer distortion in fibres and time-bin qubits on the other hand require long interferometers for qubit analysis due to the long coherence time. Here we report on the implementation of frequency-bin entanglement [2, 3] which has neither of these drawbacks.
Development of Novel Azobenzene Derivatives showing a Room Temperature Liquid-crystalline Phase and their Photoresponsive Behavior (2008)

Novel azotolane derivatives containing various structures of alkyl chains have been synthesized via palladium-catalyzed cross coupling reactions as the key step. The thermotoropic liquid crystalline behavior of these compounds was investigated by polarizing optical microscopy, differential scanning calorimeter, and X-ray scattering, and the influences of the structure and position of the lateral alkyl chain on the mesomorphic properties were studied. Depending on the size or the structure of alkyl chains, different liquid crystalline phases were detected. Furthermore, we found that all compounds show trans-cis photoisomerization behavior upon irradiation of ultraviolet light, as well as a conventional azobenzene moiety.
CICBUAPnlp: Graph-Based Approach for Answer Selection in Community Question Answering Task (2015)

This paper describes our approach for the Community Question Answering Task, which was presented at the SemEval 2015. The system should read a given question and identify good, potentially relevant, and bad answers for that question. Our approach transforms the answers of the training set into a graph based representation for each answer class, which contains lexical, morphological, and syntactic features. The answers in the test set are also transformed into the graph based representation individually. After this, different paths are traversed in the training and test sets in order to find relevant features of the graphs. As a result of this procedure, the system constructs several vectors of features: one for each traversed graph. Finally, a cosine similarity is calculated between the vectors in order to find the class that best matches a given answer. Our system was developed for the English language only, and it obtained an accuracy of 53.74 for subtask A and 44.0 for subtask B.
Signal distortion and noise in AM-SCM transmission systems employing the feedforward linearized MQW-EA external modulator (1995)

In subcarrier multiplexing (SCM) optical video distribution systems, the nonlinear signal distortion generated by the combined action of laser chirp and fiber dispersion limits the transmission distance. This paper for the first time shows that low-chirp MQW (multiquantum well)-EA (electroabsorption) external modulators are applicable to AM-SCM transmission systems. The feedforward linearization technique is used to compensate the signal distortion due to the nonlinearity in the modulator's L-V (light power versus voltage) characteristic. The effectiveness of this type of modulator for suppressing dispersion-induced distortion is clarified experimentally. A feedforward linearized transmitter with composite second order (CSO) intermodulation distortion <-62 dBc, composite triple beat (CTB) intermodulation distortion <-59 dBc and a carrier-to-noise ratio (CNR) >50.5 dB is successfully constructed. It is shown that the transmitter can achieve a CSO <-59 dBc, a CTB <-57 dBc and a CNR >49.5 dB for a 32 channel AM signal and 10 km transmission. Furthermore, estimations of the signal distortion cancellation and the noise characteristic achieved with feedforward circuit modeling are shown. The results obtained here emphasize that MQW-EA external modulators are applicable to AM-SCM transmission systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Thermally Stimulated Current Investigation of Copper Octaethylporphyrin Dimer Langmuir−Blodgett Films (2004)

Langmuir-Blodgett films containing meso,meso'-buta-1,3-diyne-bridge Cu(II) octaethylporphyrin dimer have been deposited with the aim of carrying out a thermally stimulated current (TSC) investigation. This characterization was obtained upon cooling samples irradiated by light and others without irradiation: in this way TSC curves have been registered in the temperature range of 100-300 K. Analysis of experimental data has been performed through the application of three different approaches: the initial rate, the heating rate, and Chen's methods. In particular, a trap center at about 0.38 eV has been evidenced and the three different methods have given results in close accordance.
