Performance Analysis of Magnetorheological Energy Absorbers Under Impact Conditions (2008)

Magnetorheological energy absorbers (MREAs) can provide adaptive vibration and shock mitigation capabilities to adapt to varying payloads, vibration spectra, and shock pulses, as well as other environmental factors. To effectively utilize these adaptive capabilities, the dynamic range (defined as the ratio of the force at maximum field to the force in the absence of field) or turn-up ratio is a key issue. Previous studies found that the dynamic range of a MREA significantly degraded at velocities even as low as nominally 6 m/s. To improve understanding of MREA behavior and to enable effective MREA design, which implies maintaining sufficient dynamic range over its design speeds range, this study focuses on the design, fabrication, testing, and transient impact analysis of a MREA for which the primary design objective was a dynamic range, D≥2, for nominal impact speeds of up to 6.75 m/s. The MREA was tested using the drop tower facility at GM R&amp;D Center under nominal drop speeds of up to 6 m/s. The drop test experimental results showed that the MREA achieved a dynamic range of ≥2 for nominal speeds up to 6 m/s. However, the design analysis, based primarily on a laminar Bingham-plastic model (Re &lt; 2300) failed to properly account for passive viscous losses for drop speeds above 2 m/s. Suggestions for improving the design analysis are described. To accurately predict the transient MREA force response behavior in this impact speed range, a hydromechanical model was developed and experimentally validated using results from the drop tests for nominal speeds up to 6 m/s. It was concluded that: 1) maintaining a low Reynolds number is essential to achieve a useful dynamic range, where in our case, a Re&lt;850 led to a predicted dynamic range of D≥2; and 2) the hydromechanical analysis is a useful and accurate tool for predicting this MREA transient force behavior for these drop test data.
A canine cancer-gene microarray for CGH analysis of tumors (2003)

As with many human cancers, canine tumors demonstrate recurrent chromosome aberrations. A detailed knowledge of such aberrations may facilitate diagnosis, prognosis and the selection of appropriate therapy. Following recent advances made in human genomics, we are developing a DNA microarray for the domestic dog, to be used in the detection and characterization of copy number changes in canine tumors. As a proof of principle, we have developed a small-scale microarray comprising 87 canine BAC clones. The array is composed of 26 clones selected from a panel of 24 canine cancer genes, representing 18 chromosomes, and an additional set of clones representing dog chromosomes 11, 13, 14 and 31. These chromosomes were shown previously to be commonly aberrant in canine multicentric malignant lymphoma. Clones representing the sex chromosomes were also included. We outline the principles of canine microarray development, and present data obtained from microarray analysis of three canine lymphoma cases previously characterized using conventional cytogenetic techniques.

Silicon carbide MEMS oscilator (2009)

An oscillator employing a polycrystalline 3C silicon carbide (3C-SiC) folded-beam microelectromechanical resonator as a frequency-setting component with silicon discrete electronics has been designed and demonstrated. The rocking resonant mode of the resonator is chosen due to its lower motional resistance than that of the lateral resonant mode and small frequency separation between the two modes. Further analysis reveals that an increased power handling capability can be obtained by the rocking mode without an excessive mechanical motion, which is attractive for enhancing resonator durability. The resonator achieves a quality factor of 10300 at 30.2 kHz of the rocking mode resonance under 1 mTorr pressure. The oscillator outputs a sinusoidal waveform at 30.2 kHz with an output power of −17 dBm under a 10V DC bias and achieves a phase noise of −78 dBc/Hz at 12 Hz offset frequency from the carrier, limited by the resonator power handling capability and noise floor from the interface electronics. The oscillation frequency exhibits a 16 ppm stability observed over a period of 100 hours including all environment effects.
Five Hours of Resuscitation With 150 Electrical Shocks and Complete Recovery (2021)

Our case shows that with a revisable cause of cardiac arrest, resuscitation should be directed at maintaining perfusion of essential organs and treating the reversible cause. Without re-opening the RCA, we could not have saved the patient's life. The use of an extracorporeal membrane oxygenator, if available, should be considered in similar cases. Finally, the quality of cardiopulmonary resuscitation determines the neurological outcome regardless of the length of resuscitation, as was evident in our patient who recovered completely.

Improvements in Factor Analysis Based Speaker Verification (2006)

We present the results of speaker verification experiments conducted on the NIST 2005 evaluation data using a factor analysis of speaker and session variability in 6 telephone speech corpora distributed by the Linguistic Data Consortium. We demonstrate the effectiveness of zt-norm score normalization and a new decision criterion for speaker recognition which can handle large numbers of t-norm speakers and large numbers of speaker factors at little computational cost. The best result we obtained was a detection cost of 0.016 on the core condition (all trials) of the evaluation
Toward a typology of health 2.0 collaboration platforms and websites (2012)

During the past decade, the proliferation of social media has infiltrated various sectors of social and business communications. Of particular interest is the growth of health related websites and the healthcare sector’s adoption of social media. In this paper, we develop a typology of Health 2.0 collaboration platforms and websites. Two major types of actors within Health 2.0 websites are health professionals (P) and health consumers (C). Each actor can serve as either support provider or support recipient. We focus on the six major Health 2.0 collaboration platforms including health blogs, physician-ratings, medicine-ratings, online health social networks, health discussion boards, and ask-a-doctor. We categorize these platforms into four major types including professional-to-professional (P2P), professional-to-consumer (P2C), consumer-to-consumer (C2C), and consumer-to-professional (C2P). Then, based on the combination of collaboration platforms provided by Health 2.0 websites, we categorize these websites into P2P, P2C, C2C, and C2P types. We describe each type and utilize the typology to investigate 20 Health 2.0 websites and the collaboration platforms they provide. Our typology can be used as groundwork for future research on health social media.
Light chain amyloidosis (2018)

Light chain (AL) amyloidosis is caused by a usually small plasma-cell clone that is able to produce the amyloidogenic light chains. They are able to misfold and aggregate, deposit in tissues in the form of amyloid fibrils and lead to irreversible organ dysfunction and eventually death if treatment is late or ineffective. Cardiac damage is the most important prognostic determinant. The risk of dialysis is predicted by the severity of renal involvement, defined by the baseline proteinuria and glomerular filtration rate, and by the response to therapy. The specific treatment is chemotherapy targeting the underlying plasma-cell clone. It needs to be risk-adapted, according to the severity of cardiac and/or multi-organ involvement. Autologous stem cell transplant (preceded by induction and/or followed by consolidation with bortezomib-based regimens) can be considered for low-risk patients (~20%). Bortezomib combined with alkylators is used in the majority of intermediate-risk patients, and with possible dose escalation in high-risk subjects. Novel, powerful anti-plasma cell agents were investigated in the relapsed/refractory setting, and are being moved to upfront therapy in clinical trials. In addition, the use of novel approaches based on antibodies targeting the amyloid deposits or small molecules interfering with the amyloidogenic process gave promising results in preliminary studies. Some of them are under evaluation in controlled trials. These molecules will probably add powerful complements to standard chemotherapy. The understanding of the specific molecular mechanisms of cardiac damage and the characteristics of the amyloidogenic clone are unveiling novel potential treatment approaches, moving towards a cure for this dreadful disease.
[Effects of human atrial natriuretic polypeptide in a patient with acute pulmonary edema during living-related kidney transplantation]. (1999)

A 19-year-old female was scheduled for living-related kidney transplantation under general anesthesia. Eight units of fresh frozen plasma were infused in 30 minutes before the recanalization of renal vessels. Twenty minutes after the first urination, end-tidal-CO2 suddenly increased showing CVP of 18 mmHg. We considered that she had developed acute pulmonary edema. Continuous hANP infusion was initiated at the rate of 0.1 microgram.kg-1.min-1. By this infusion, end-tidal-CO2 and CVP gradually decreased and operation was concluded successfully. This case demonstrates that hANP works also on the transplanted kidney.

X-ray properties of the galactic jet sources (1999)

X-ray properties of the Galactic jet sources are studied using the ASCA data.Two different types are found in the jet sources. One type, represented by the superluminal jet sources GRO J1655–40 and GRS1915+105, includes a rapidly rotating compact star (a black hole or a neutron star) receiving super-critical mass accretion. On the other hand, relatively dim sources, such as GX339–4, 1E1740.7–2942 and GRS 1758–258, may constitute of the other type, which can produce jets at luminosities much lower than the Eddington limit.
A new algorithm for finite spectrum assignment of single-input systems with time delay (1992)

Finite spectrum assignment for time-delay systems is the elimination of delay operators from the characteristic function of the closed-loop system and the arbitrary assignment of poles. The control consists of polynomials in the delay operator and finite Laplace transforms. An algorithm for computing the control matrix is presented. In particular, the control matrix over rational functions of a delay operator is computed and expanded to partial fractions. Partial fractions are systematically transformed to finite Laplace transforms.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

A Loosely Coupled Planar Wireless Power Transfer System Supporting Multiple Receivers (2010)

A high-efficiency wireless power transfer system which is capable of supporting more than one receiver using class E operation for transmitter via inductive coupling has been designed and fabricated. The design approach of the system is also presented in this paper. The system requires no complex external control system but relies on its natural impedance response to achieve the desired power delivery profile across a wide range of load resistances while maintaining high efficiency to prevent any heating issues. A switch circuit is used to decouple the fully charged receiver from the system so that power delivery to the other receiver can be improved. The fabricated system at 12 V supply voltage is compact and capable of approximately 2.5 W of power delivery to each of the two receivers in a dual receiver setup and 5 W to a single receiver alone or when the other receiver is decoupled by the receiver switch. During high-power delivery state, the system efficiency is between 67.5% and 77.5%.

Stanford Racing Team's Entry In The 2005 DARPA Grand Challenge (2005)

The Stanford Racing Team (SRT) has successfully developed an autonomous robotic vehicle capable of driving through desert terrain without human intervention. The SRT vehicle Stanley is based on a reinforced Volkswagen Touareg, equipped with a custom drive-by-wire system, a sensor rack, and a computing system. The vehicle is controlled through a distributed software system that uses inertial sensing for pose estimation, and lasers, vision, and RADAR for environmental perception. Sensor data is mapped into a drivability map, which is used to set the direction and velocity of the vehicle. A major emphasis of the SRT has been early development of a prototype end-to-end system, to enable extensive testing in authentic desert terrain.
Matrix ENDOR of polyenyl radicals in polymers (1975)

Abstract EPR and matrix ENDOR spectra have been examined for polyenyl radicals in γ‐irradiated PVF, PVF 2 , PVC, and PMMA polymers. Proton matrix ENDOR is observed for all four polymers, and fluorine matrix ENDOR for PVF and PVF 2 . By line shape analysis of the ENDOR spectra obtained under comparable conditions, delocalization diameters for the unpaired electron of the polyenyl radical in each polymer are obtained. These diameters indicate extensive delocalization over 5–7 carbon double bonds for the polyenyl radicals investigated. It is suggested that these conjugated and crosslinked radiation products account for the observed nondevelopment of electron beam resist PMMA material at high radiation charge densities.

Design details are discussed, along with combustion speed, heat transfer coefficient, reliability testing, and emissions. The chamber is intended primarily for railroad locomotives.&lt;/div&gt;
Transient Growth in Hypersonic Boundary Layers (2014)

This paper investigates the relative importance of modal and non-modal growth mechanisms in flat-plate, hypersonic boundary layers as well as the effects of Mach number and wall cooling on these processes. Optimal disturbances are calculated in both the spatial and temporal frameworks using an eigenvector decomposition of the locally-parallel, linearized Navier-Stokes equations. It is found that for every Mach number there is an optimal level of wall cooling that minimizes transient growth; at this condition the wall temperature is slightly below the freestream temperature, with lower wall temperatures needed as the Mach number increases. The competition between modal and non-modal growth mechanisms is examined over a range of Reynolds numbers by calculating N factor curves for both processes. For conditions relevant to high enthalpy flows (high Mach number, cold wall), transient growth is rapidly overtaken by modal instabilities while the level of amplification remains small. At lower Mach numbers or adiabatic conditions, the transient growth is overtaken more slowly. For low supersonic Mach numbers and cold walls there are no modal instabilities, but the level of non-modal amplification is increased such that the initiation of transition by infinitesimal perturbations is plausible despite the absence of modal instabilities.
Millimeter-Wave Reflector Based on a Ferroelectric Material with Electrical Beam Steering (2021)

Millimeter waves are increasingly used in modern telecommunication systems for wireless data transmission. However, higher path loss, especially caused by non-line-of-sight scenarios, remains challenging. The design of an electrically controllable reflector for the millimeter-wave range is elaborated and presented in this manuscript. The reflector design was based on distributed ferroelectric ceramic elements and could be used in a frequency range up to 100 GHz. The issue of the ferroelectric reflector impedance matching was analyzed in detail. Two possible implementations of the reflector for indoor and outdoor communication systems were considered and simulated. The prototype of the proposed reflector for an operating frequency of 60 GHz was manufactured. Both simulation and measurement results demonstrated the beam steering by the proposed ferroelectric reflector.

Abstract A44: 18F-FLT, a potential biomarker for predicting the synergistic combination of PI3K inhibitor BAY 80-6946* and MEK inhibitor BAY 86-9766. (2011)

Abstract Signaling pathways of particular interest in the cancer field are the RAS-RAF-MEK and PI3K-AKT pathways that act as parallel conduits to transduce signals involved in tumor cell proliferation, survival, and cell migration. Compared to targeting either pathway separately, simultaneous inhibition of these two key pathways has been considered to have greater therapeutic efficacy and broader applicability for the treatment of cancers. One of the challenges is the discovery of biomarkers that correlate with efficacy and synergy of PI3K and MEK combination therapy in early-stage clinical trials. To identify the best imaging tracer for monitoring the synergistic anti-tumor activity of BAY 80-6946* and BAY 86-9766, we first compared FDG and FLT uptake in vitro in 2 colorectal (CRC) and 2 non-small cell lung cancer (NSCLC) cell lines bearing either KRAS or KRAS plus PIK3CA mutations. Partial inhibition of FDG- and FLT-uptake (&amp;lt;50%) was observed in tumor cells treated with each agent, while synergistic and complete inhibition of FLT-uptake (&amp;gt;94%) was demonstrated in the combination group. Interestingly, the maximum inhibition of FDG-uptake was much weaker compared to FLT-uptake, indicating that FLT might be a better tracer for PI3K and MEK combination therapy. Further investigation iwas conducted in HCT116 CRC xenografts in mice and H460 NSCLC xenografts in rats. BAY 80-6946* was administered intraveneously (Q2D) at 14 mg/kg in mice and at 3 mg/kg in rats whereas BAY 86-9766 was dosed orally (QD) at 25 mg/kg in mice and at 15 mg/kg in rats. Tumor uptake of 18F-FLT was investigated by PET imaging as well as by quantitative biodistribution 1 day before and 1 day after treatment start. In both models, 18F-FLT tumor uptake was not significantly altered in animals treated with each single agent. However, one day after the treatment in the combination group, 18F-FLT tumor uptake was reduced from 8.50±0.99 %ID/g to 3.91±0.66 %ID/g (n=5, vs vehicle, p&amp;lt;0.05) in HCT116 bearing mice and from 0.91±0.27 %ID/g to 0.31±0.04 %ID/g (n=5, vs vehicle, p&amp;lt;0.05) in H460 bearing rats. Inhibition of 18F-FLT uptake in tumors ocurred before any significant reduction in tumor volume and correlates with tumor growth inhibition assessed by the tumor size at the later time points. Further detailed molecular mechanism on the synergistic inhibition of 18F-FLT uptake by combination of PI3K and MEK inhibitors will be presented. In conclusion, 18F-FLT might be a non-invasive PET imaging tracer that, when used serially ealy in treatment, may predict clinical efficacy and combination synergy of PI3K and MEK inhibitors.
