Optical measurement of flying-heitht change due to thermal protrusion of magnetic head (2006)

To achieve an ultra-low flying height in magnetic head sliders for next generation hard disk drives, we are investigating individual in-situ technique to adjust flying height using a built-in thermal actuator to compensate for flying-height deviations and variations. To resolve this lack of agreement, we optically evaluated the slider's flying height at multiple positions using flying-height tester. We predicted compensation effect by modified air bearing simulator that takes into account of thermal protrusion.
Impaired T- and B-cell development in Tcl1-deficient mice (2004)

TCL1, the overexpression of which may result in T-cell leukemia, is normally expressed in early embryonic tissues, the ovary, and lymphoid lineage cells. Our analysis of mouse B-lineage cells indicates that Tcl1 expression is initiated in pro-B cells and persists in splenic marginal zone and follicular B cells. T-lineage Tcl1 expression begins in thymocyte progenitors, continues in CD4(+)CD8(+) thymocytes, and is extinguished in mature T cells. In Tcl1-deficient mice, we found B lymphopoiesis to be compromised at the pre-B cell stage and T-cell lymphopoiesis to be impaired at the CD4(+)CD8(+) thymocyte stage. A corresponding increase was observed in thymocyte susceptibility to anti-CD3epsilon-induced apoptosis. Reduced numbers of splenic follicular and germinal center B cells were accompanied by impaired production of immunoglobulin G1 (IgG1) and IgG2b antibodies in response to a T-dependent antigen. The marginal zone B cells and T-cell-independent antibody responses were also diminished in Tcl1(-/-) mice. This analysis indicates a significant role for Tcl1, a coactivator of Akt signaling, in normal T- and B-cell development and function.
WiMAC (2015)

This demo presents WiMAC, a general-purpose wireless testbed for researchers to quickly prototype a wide variety of real-time MAC protocols for wireless networks. As the interface between the link layer and the physical layer, MAC protocols are often tightly coupled with the underlying physical layer, and need to have extremely small latencies. Implementing a new MAC requires a long time. In fact, very few MACs have ever been implemented, even though dozens of new MAC protocols have been proposed. To enable quick prototyping, we employ the mechanism vs. policy separation to decompose the functionality in the MAC layer and the PHY layer. Built on the separation framework, WiMAC achieves the independence of the software from the hardware, offering a high degree of function reuse and design flexibility. Hence, our platform not only supports easy cross-layer design but also allows protocol changes on the fly. Following the 802.11-like reference design, we demonstrate that deploying a new MAC protocol is quick and simple on the proposed platform through the implementation of the CSMA/CA and CHAIN protocols.
Linking TV Programs with Internet Contents based on Video Fingerprinting (2006)

This paper proposes a system that provides TV/Internet converged services by linking video segments in TV programs with their related Internet contents without forcing any changes to TV contents. This system allows users to access the Internet contents related to the video clips currently played back. A robust video fingerprinting method is employed to link video segments with its related contents. Experimental results show that this system makes it possible to create those links fully automatically with no errors
Crystal structure of dunnione p-bromophenylhydrazone (1980)

The crystal structure of dunnione p-bromophenylhydrazone has been determined by single-crystal X-ray diffraction methods at 295 K, the structure being refined to a residual of 0.054 for 1429 'observed' reflections. Crystals are triclinic, Pi, a 15.620(8), b 8.804(4), c 7.439(4) ?, a 68.03(4), ß 89.85(4), ? 77.44(4)°, Z 2. The conjugation throughout the molecule is extensive and the crystal packing is dominated by intermolecular charge-transfer interactions. Bonding in the hydrazone moiety lies intermediate between those expected for hydrazone and azo forms.
Development of an optimal driver command interpreter for vehicle dynamics control (2015)

This paper introduces a new driver command interpreter (DCI) for vehicle dynamics control, providing optimal calculation of desired CG forces and moments based on driver inputs and road conditions. The proposed DCI is established based on principles of optimal linear quadratic regulator (LQR) theory and vehicle dynamics. The optimal feed-forward and feedback gains of proposed DCI can be updated in real time by online matrix calculation. Analytical simulations and experimental test results under various driving conditions are presented to evaluate the proposed DCI and vehicle dynamics control system. The simulation and experimental results indicate that the vehicle dynamics control system using the proposed DCI can effectively stabilise the vehicle motion and improve the vehicle handling under critical driving conditions.
Aluminum top-gate ZnO nanowire transistors with improved transconductance (2011)

Field-effect transistors (FETs) based on semiconducting nanowires are potentially useful to replace thin-film transistors (TFTs) in active-matrix displays, since the larger mobility and smaller footprint of nanowire FETs compared with a-Si:H and organic TFTs provide faster pixel charging and larger aperture ratio. Nanowire growth often requires high temperatures, but if the nanowires can be grown on a temperature-compatible substrate and then be transferred to the target substrate for FET fabrication, and if the temperature during FET fabrication is below ∼150 °C, nanoscale FETs can be fabricated on polymeric substrates for flexible displays.

PC-1D installation manual and user's guide (1991)

PC-1D is a software package for personal computers that uses finite-element analysis to solve the fully-coupled two-carrier semiconductor transport equations in one dimension. This program is particularly useful for analyzing the performance of optoelectronic devices such as solar cells, but can be applied to any bipolar device whose carrier flows are primarily one-dimensional. This User's Guide provides the information necessary to install PC-1D, define a problem for solution, solve the problem, and examine the results. Example problems are presented which illustrate these steps. The physical models and numerical methods utilized are presented in detail. This document supports version 3.1 of PC-1D, which incorporates faster numerical algorithms with better convergence properties than previous versions of the program. 51 refs., 17 figs., 5 tabs.

Here we report a straightforward method for the synthesis of a water-soluble C60 fullerene derivative decorated with five residues of phosphonic acid. Self-assembly of the synthesized compound in aqueous solution leads to the formation of nanostructures with unprecedented myogenic and antiviral activity.
Resource Allocation in Coordinated Uplink Multicell Multicarrier Systems (2013)

We consider joint optimization of transmit power, serving base station cluster (BSC) for coherent reception, beamforming and subcarrier allocation for the uplink channel of a multicell multicarrier system. The objective is to minimize the sum transmit power subject to user-specific rate constraints. Since the problem is nonconvex and NP-hard, finding the optimal solution is challenging and not practically appealing. We propose two bit loading algorithms, in which the data rate of users is iteratively increased until the rate targets are satisfied. A joint power control, BSC selection and beamforming design problem with fixed rate allocation per subcarrier is optimally solved in every iteration. A bit switching (BSW) algorithm is further proposed in order to search for better rate allocations. The performances of the proposed algorithms are compared to upper and lower bounds achieved by the capacity-achieving scheme and equal rate allocation over subcarriers (ER), respectively. Simulation results show that proposed algorithms achieve significantly better performance than the ER scheme. The performance gains become larger as the number of users is increased.
Audio Capture Using Structural Sensors on Vibrating Panel Surfaces (2022)

The microphones and loudspeakers of modern compact electronic devices such as smartphones and tablets typically require case penetrations that leave the device vulnerable to environmental damage. To address this, the authors propose a surface-based audio interface that employs force actuators for reproduction and structural vibration sensors to record the vibrations of the display panel induced by incident acoustic waves. This paper reports experimental results showing that recorded speech signals are of sufficient quality to enable high-reliability automatic speech recognition despite degradation by the panel's resonant properties. The authors report the results of experiments in which acoustic waves containing speech were directed to several panels, and the subsequent vibrations of the panels' surfaces were recorded using structural sensors. The recording quality was characterized by measuring the speech transmission index, and the recordings were transcribed to text using an automatic speech recognition system from which the resulting word error rate was determined. Experiments showed that the word error rate (10%-13%) achieved for the audio signals recorded by the method described in this paper was comparable to that for audio captured by a high-quality studio microphone (10%). The authors also demonstrated a crosstalk cancellation method that enables the system to simultaneously record and play audio signals.
On the Fairness of the Reverse-Link MAC Layer in cdma2000 1xEV-DO (2004)

We investigate the fairness of two reverse-link MAC algorithms in cdma2000 1xEV-DO High Rate Packet Data systems. Following the framework proposed by Kelly [1] for Internet congestion-control, we formulate a utility maximization problem and provide a simple sufficient condition for both algorithms to converge to the solution of this problem. Furthermore, we identify that the solution of this problem corresponds to the equal throughput fairness criteria, i.e., all the access terminals have equivalent throughput at the equilibrium. 1
Transimmunization restores immune surveillance and prevents recurrence in a syngeneic mouse model of ovarian cancer (2020)

Ovarian cancer accounts for most deaths from gynecologic malignancies. Although more than 80% of patients respond to first-line standard of care, most of these responders present with recurrence and eventually succumb to carcinomatosis and chemotherapy-resistant disease. To improve patient survival, new modalities must, therefore, target or prevent recurrent disease. Here we describe for the first time a novel syngeneic mouse model of recurrent high-grade serous ovarian cancer (HGSOC), which allows immunotherapeutic interventions in a time course relevant to human carcinomatosis and disease course. Using this model, we demonstrate the efficacy of Transimmunization (TI), a dendritic cell (DC) vaccination strategy that uses autologous and physiologically derived DC loaded with autologous whole tumor antigens. TI has been proven successful in the treatment of human cutaneous T cell lymphoma and we report for the first time its <i>in vivo</i> efficacy against an intra-peritoneal solid tumor. Given as a single therapy, TI is able to elicit an effective anti-tumor immune response and inhibit immune-suppressive crosstalks with sufficient power to curtail tumor progression and establishment of carcinomatosis and recurrent disease. Specifically, TI is able to inhibit the expansion of tumor-associated macrophages as well as myeloid-derived suppressive cells consequently restoring T cell immune-surveillance. These results demonstrate the possible value of TI in the management of ovarian cancer and other intra-peritoneal tumors.
Accumulation of electric-field-stabilized geminate polaron pairs in an organic semiconductor to attain high excitation density under low intensity pumping (2006)

The recombination dynamics of geminate polaron pair (PP) states are investigated by monitoring electric-field-induced delayed fluorescence in thin films consisting of the green laser dye, Coumarin-6 (C6) doped at 1wt% into 4,4′-bis(N-carbazolyl)biphenyl. We find that the PP decay follows τ−m (with m∼0.1), where τ is the time that the PPs are held in the field. This sublinear decay suggests the possibility for accumulation of PPs over time that can then be reconverted into excitons upon field removal. We demonstrate the generation of short (∼50ns full width at half maximum) bursts of C6 fluorescence with peak intensities &amp;gt;20 times the steady-state fluorescence intensity (corresponding to a C6 singlet exciton density NS&amp;gt;4×1015cm3) when pumped continuously by a low intensity (&amp;lt;1W∕cm2) laser in the presence of a pulsed electric field.
Conformational Switch to a β-Turn in a Staphylococcal Quorum Sensing Signal Peptide Causes a Dramatic Increase in Potency (2019)

We report the solution-phase structures of native signal peptides and related analogs capable of either strongly agonizing or antagonizing the AgrC quorum sensing (QS) receptor in the emerging pathogen <i>Staphylococcus epidermidis</i>. Chronic <i>S. epidermidis</i> infections are often recalcitrant to traditional therapies due to antibiotic resistance and formation of robust biofilms. The accessory gene regulator (<i>agr</i>) QS system plays an important role in biofilm formation in this opportunistic pathogen, and the binding of an autoinducing peptide (AIP) signal to its cognate transmembrane receptor (AgrC) is responsible for controlling <i>agr</i>. Small molecules or peptides capable of modulating this binding event are of significant interest as probes to investigate both the <i>agr</i> system and QS as a potential antivirulence target. We used NMR spectroscopy to characterize the structures of the three native <i>S. epidermidis</i> AIP signals and five non-native analogs with distinct activity profiles in the AgrC-I receptor from <i>S. epidermidis</i>. These studies revealed a suite of structural motifs critical for ligand activity. Interestingly, a unique β-turn was present in the macrocycles of the two most potent AgrC-I modulators, in both an agonist and an antagonist, which was distinct from the macrocycle conformation in the less-potent AgrC-I modulators and in the native AIP-I itself. This previously unknown β-turn provides a structural rationale for these ligands' respective biological activity profiles. Development of analogs to reinforce the β-turn resulted in our first antagonist with subnanomolar potency in AgrC-I, while analogs designed to contain a disrupted β-turn were dramatically less potent relative to their parent compounds. Collectively, these studies provide new insights into the AIP:AgrC interactions crucial for QS activation in <i>S. epidermidis</i> and advance the understanding of QS at the molecular level.
IMMUNOGENICITY OUTCOMES OF A RANDOMIZED, MULTICENTER, INTERVENTIONAL, FIRST-IN-HUMAN, PHASE 1/2A STUDY OF VAC52416 (EXPEC10V), A VACCINE CANDIDATE FOR THE PREVENTION OF INVASIVE ESCHERICHIA COLI DISEASE (2023)

stantiated events were greatest in the WHO African Region (1684 events, 31%) and the WHO Region of the Americas (1312 events, 24%) and, similarly, by year, the burden was highest in those WHO regions.Globally, over time, two-thirds (3536, 65%) of substantiated events were initially reported by WHO and infectious diseases (4298, 79%) were the predominant cause of public health events.However, other causes, including animal origin or zoonoses were also important and disaster related events were on the rise in recent years, particularly in some WHO Regions.Conclusion: WHO has a robust system for global disease detection but health threats are continuously evolving.The impact of climate change and zoonoses is becoming more pronounced, emphasizing the importance of a One Health approach for disease detection.
Joint reconstructions of CO2 plumes using a Markov Chain Monte Carlo approach (2006)

We describe a stochastic inversion method for mapping subsurface regions where CO{sub 2} saturation is changing. The technique combines prior information with measurements of injected CO{sub 2} volume, reservoir deformation and electrical resistivity. Bayesian inference and a Metropolis simulation algorithm form the basis for this approach. The method can (a) jointly reconstruct disparate data types such as surface or subsurface tilt, electrical resistivity, and injected CO{sub 2} volume measurements, (b) provide quantitative measures of the result uncertainty, (c) identify competing models when the available data are insufficient to definitively identify a single optimal model and (d) rank the alternative models based on how well they fit available data. We use measurements collected during CO{sub 2} injection for enhanced oil recovery to illustrate the method's performance. The stochastic inversions provide estimates of the most probable location, shape, volume of the plume and most likely CO{sub 2} saturation. The results suggest that the method can reconstruct data with poor signal to noise ratio.

Tantalum Oxide???A Non-Explosive Substitute for Metallic Tantalum Powder (1973)

Tantalum powder is now being used as a bronchographic agent. Like most metal powders, tantalum powder carries an exposion hazard when nebulized. Therefore, we have tested non-explosive tantalum oxide (Ta2O5) as a substitute for metallic tantalum powder. No precautionary measures need be taken when tantalum oxide is used for bronchography. Although the radiodensity of tantalum oxide is less than that of tantalum by a factor of 0.5 per volume and 0.8 per mass, some technical advantages make it superior to metallic tantalum. The chemical inertness and the biological properties of tantalum and tantalum oxide are similar. No fibrogenic reactions due to non-cleared deposits have been found for up to one year in either man or experimental animals.
Amorphous-silicon solar cells with screen-printed metallization (1990)

The use of screen printing for the back-side metallization of amorphous-silicon solar cells on glass is proposed. Compared with the conventional aluminum evaporation process, screen printing is attractive because if offers high throughput and because direct patterning is performed during the printing process. The critical point in realizing a thick-film screen-printed contact on amorphous-silicon solar cells is found to be the contact resistivity between the contact and the n-layer. Contact resistivities below 1 Omega -cm/sup 2/ have been obtained using a microcrystalline instead of an amorphous n/sup +/ layer and a screen-printed contact based on Mo, Ti, or Ni. Amorphous-silicon solar cells with a screen-printed back contact had a performance comparable with that of cells with an evaporated Al contact, resulting in an efficiency of 9.7%. Spectral response measurements demonstrated that the screen-printed contact is an efficient reflector of long-wavelength photons, resulting in a high red response due to internal light trapping.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Characteristics of Pr[sub 2]O[sub 3] Gate Dielectric Thin-Film Transistors Fabricated on Fluorine-Ion-Implanted Polysilicon Films (2007)

A simple and effective scheme for fabricating high dielectric constant (high-κ) praseodymium oxide gate dielectric thin-film transistors ( TFT) on fluorine-ion-implanted polysilicon films was proposed and demonstrated for the first time. Incorporating the fluorine-incorporation method with high-κ gate dielectric cannot only effectively passivate the trap states in the poly-Si film but also significantly increase the gate capacitance density. With the incorporation of fluorine ions, the electrical characteristics of TFT can be remarkably improved, including smaller threshold voltage, steeper subthreshold swing, higher field-effect mobility, lower gate-induced drain leakage current, and better on/off current ratio. In addition, the incorporation of fluorine ions in the poly-Si film also improves the reliability of TFT against hot-carrier stress, which is attributed to the formation of stronger bonds. Therefore, the proposed scheme is a promising technology for high-performance solid-phase crystallized poly-Si TFTs.
