Rate-one space-frequency block codes with maximum diversity for MIMO-OFDM (2005)

We propose a novel rate-one (i.e., one symbol per transmission), space-frequency block code (SFBC) for an orthogonal frequency division multiplexing (OFDM) system with transmit (M), and receive (N) antennas that achieves the maximum diversity attainable over frequency-selective channels. Moreover, the space-frequency (SF) code design is shown to be robust to overestimation of the (true) channel order L at the price of increasing decoding complexity. Further, even if the channel order is underestimated (K<L), diversity order of MNK is achieved with commensurately reduced decoding complexity; this allows a natural mechanism for trading diversity for decoding complexity as desired. In addition, since the SF code symbol is transmitted in one OFDM block duration, it has a smaller processing delay than comparable space-time-frequency block codes (STFBC).

Estimating desired yaw rate and control strategy analysis on developed air ESC system for performance evaluation (2015)

The leading automotive manufacturers have attempted to apply active brake systems to passenger and commercial vehicles. The ESC (electronic stability control) system helps drivers to maintain directional stability and control over steering and under steering. Previous studies on passenger vehicle ESC systems have mainly dealt with the control algorithm and evaluation results. In addition, few papers have considered bus and commercial ESC systems. Therefore, this study proposed a method for estimating the desired yaw rate using the already developed ESC system. The desired yaw rate is estimated from the steering wheel angle, vehicle speed, and vehicle parameters. This paper presents the results of a sine with dwell evaluation analysis of a large bus equipped with an ESC system. Through this process, we are able to estimate the ESC control strategy of the leading producer of commercial buses based on an air brake system. The bus ESC evaluation results can be used as a reference for the development of the ESC control algorithm.
Alert Driven Communications Management for Children Music Learning Based on Suzuki Method (2015)

It is widely believed that parents' involvement in students' music learning is vital to their success. Shinichi Suzuki not only provided teachers with useful and logical teaching skills, but also stressed on the importance of the parents as a “home teacher”. To enhance the interactions among parents, students, and teachers as well as encourage parental participation, this paper proposes a Web 2.0 learning platform (WASSAP) with an Alert Management System (AMS) as a solution to tackle problems of busy parents who do not have adequate time to involve in students' music learning. The system can facilitate busy parents to pay more attention to students' learning progress, with the AMS managing the underlining communication among various parties involved.
186 K operation of terahertz quantum-cascade lasers based on a diagonal design (2009)

Resonant-phonon terahertz quantum-cascade lasers operating up to a heat-sink temperature of 186 K are demonstrated. This record temperature performance is achieved based on a diagonal design, with the objective to increase the upper-state lifetime and therefore the gain at elevated temperatures. The increased diagonality also lowers the operating current densities by limiting the flow of parasitic leakage current. Quantitatively, the diagonality is characterized by a radiative oscillator strength that is smaller by a factor of two from the least of any previously published designs. At the lasing frequency of 3.9 THz, 63 mW of peak optical power was measured at 5 K, and approximately 5 mW could still be detected at 180 K.
The effect of calcium phosphate ceramic composition and structure on <i>in vitro</i> behavior. II. Precipitation (1993)

The formation of a biologically equivalent carbonate-containing apatite on the surface of synthetic calcium phosphate ceramics (CPC) may be an important step leading to bonding with bone. Reactions of several single phases CPCs upon immersion into a simulated physiologic solution (SPS) with an electrolyte composition of human plasma were determined. The CPCs covered a wide range of solution stabilities from low-soluble hydroxyapatites (HA) to metastable tricalcium phosphates (TCP) and tetracalcium phosphate (TTCP). Changes in chemical compositions of SPS and infrared spectral features after CPC immersion were analyzed. New phase formation was observed on all the CPCs. However, kinetics, compositions, and structures of the new phases were significantly different. The studied CPCs can be characterized by the time to new phase formation in vitro; the minimum time for measurable precipitate formation was found to increase in the order: not-well-crystallized HAs < well-crystallized HAs < alpha-TCP, TTCP < beta-TCP. Among the CPCs only not-well-crystallized HAs led to immediate new phase formation. The metastable CPCs, beta-TCP, alpha-TCP, and TTCP required an induction time during which dissolution occurred. beta-TCP showed the longest induction time and the lowest lattice ion uptake rate of all the CPCs tested. Only the not-well-crystallized HAs elicited immediate formation of carbonated HA. The well-crystallized HAs and beta-TCP did not elicit carbonated apatite formation within the time frame of the experiment. Instead, intermediate phases were formed. On alpha-TCP amorphous calcium phosphate (ACP) with a relatively low carbonate content was formed. TTCP was found to transform extensively to poorly crystallized carbonated apatite after 2 days of immersion.

Replay debugging for distributed applications (2006)

Researchers in networks and computer systems have developed exciting new distributed applications in recent years; however, adoption of real-world prototypes has been slow. The development of stable, usable services has been hindered by the tremendous effort required to debug distributed applications that are deployed across the Internet. We believe that more powerful debugging tools are needed to address this problem. This dissertation presents the progress we have made on this front, in the form of two new tools, Liblog and Friday. <p> The first, Liblog, is a replay debugging library for libc- and POSIX-based distributed applications. It logs the execution of deployed application processes and replays them deterministically, faithfully reproducing race conditions and non-deterministic failures, enabling careful offline analysis. <p> To our knowledge, Liblog is the first replay tool to address the requirements of large distributed systems: lightweight support for long-running programs, consistent replay of arbitrary subsets of application nodes, and operation in a mixed environment of logging and non-logging processes. In addition, it runs on generic Linux/x86 computers without special hardware or kernel patches and supports unmodified application executables. <p> The second tool, Friday, combines the deterministic replay provided by Liblog with the power of symbolic, low-level debugging and a simple language for expressing higher-level distributed conditions and actions. Friday allows the programmer to understand the collective state and dynamics of a distributed collection of coordinated application components, as part of the debugging process. <p> This dissertation presents the design of Liblog and Friday, an evaluation of the performance overhead that they impose at runtime, and a set of case studies that illustrate the new functionality enabled for real distributed applications
Click Models for Web Search and their Applications to IR (2016)

In this tutorial we give an overview of click models for web search. We show how the framework of probabilistic graphical models helps to explain user behavior, build new evaluation metrics and perform simulations. The tutorial discusses foundational aspects alongside experimental details and applications, with live demos and discussions of publicly available resources.
TULIP at Carnegie Mellon (1995)

The TULIP (The University Licensing Project) data were integrated into the Carnegie Mellon Library Information System (LIS) in 1994. The bibliographic data were released to campus in April and the image data in June. All electronic library information resourc‐es—bibliographic, ASCII full text, image full text, and selected Telnet sessions—are available through the LIS user interface. This provides the user with “one‐stop shopping,” a longstanding goal of the LIS/Mercury project at Carnegie Mellon.
Thermal stability of Ti/Pt/Au nonalloyed ohmic contacts on InN (1994)

Extremely low contact resistance of nonalloyed Ti/Pt/Au metallization on n-type InN is demonstrated. The contacts were annealed at different temperatures up to 420 °C to investigate their thermal stability. A low contact resistivity of 1.8×10−7 Ω cm2 was measured at room temperature using the transmission line method. This was due to the extremely high doping level (5×1020 cm−3) in the InN. After 300 °C annealing, the contact resistivity increased to 2.4×10−7 Ω cm2. For 360 °C annealing, the contact morphology showed some degradation, but the contact resistivity was almost the same as at 300 °C. There was serious degradation of the contacts after 420 °C annealing. The morphology became very rough, and the contact and sheet resistances increased by factors of 3–5 times. This degradation is believed due to the decomposition of the InN film. The contact resistivities between n-type epitaxial GaAs and InN were also investigated, and showed values around 10−4 Ω cm2.
The Hong Kong Law Enforcement Torch Run: An Exploration of Officers' Participation Motives (2009)

This study utilized the social exchange theory to examine motives of disciplinary officers participating in the Hong Kong 2005 Law Enforcement Torch Run®. Motive similarities were found between the 400 male and 103 female officers from the disciplinary forces of Police Force, Correctional Services, Customs and Excise Services, Fire Services, Government Flying Services, Immigration Department, and the Independent Commission Against Corruption. The nature of espoused motives, in their order of popularity was Purposive, Material, and Solidary in nature. However, among those participants who returned year after year, the primal motives were of the Purposive and Material in nature. Promotional strategies to encourage greater participation were developed according to the findings.
A recurrent neural network for solving variational inequality problems with nonlinear constraints (2005)

Variational inequalities with nonlinear inequality constraints are widely used in optimization and engineering problems. This paper present a recurrent neural network for solving variational inequalities with nonlinear inequality constraints in real time. The proposed neural network has one-layer structure and is amenable to parallel implementation. The proposed neural network is a significant generalization of several existing neural networks for optimization. Moreover, the proposed neural network is stable in the sense of Lyapunov and globally convergent to an optimal solution under a strictly monotone condition of the mapping. The simulation shows that the proposed neural network is effective for solving this class of variational inequality problems.
Binding studies of SV40 T-antigen to SV40 binding site II (1985)

SV40 T-Antigen binding site II was synthesized, cloned and analyzed for its ability to bind purified SV40 T-antigen. We report the binding constant of T-antigen for isolated site II. Using a filter binding assay the calculated binding constant was 6-8 fold less efficient than site I previously reported. Binding constants were calculated using two methods. The first was a direct calculation using a protein titration curve (KD). The second was by the ratio of measured association and dissociation rates. Both methods gave similar constants. Protection studies with SV40 T-antigen on the T-antigen binding sites in the wild-type array demonstrated that the binding constants of site I and site II are similar to those calculated for the individual sites. These results demonstrate that SV40 T-antigen does not bind cooperatively to sites one and two as earlier believed and are in agreement with recent observations emanating from several laboratories.
A NEW SYSTEM FOR MEASUREMENT OF THE PULSE TRANSIT TIME, THE PULSE WAVE VELOCITY AND ITS ANALYSIS (2016)

Arterial stiffness is a strong determinant of cardiovascular risk. Pulse wave velocity (PWV) is an index of arterial stiffness, and its prognostic value has been repeatedly emphasized. The work presented in this paper is concerned with the design of a new system for measurement of the PWV and analysis. It is in fact related to the description of the hardware setup and the software development in order to measure and analyze the PWV. In the proposed system, the determination of the PWV is carried out through the measurement of the pulse wave transit time (PWTT) using the electrocardiogram (ECG) and the photoplethysmogram (PPG) and the distance separating the site of ejection of the systolic pulse and the site of measuring the PPG signal. The hardware setup therefore consists of an optical device to detect the PPG and electrodes to detect ECG, and different boards to process and digitalize these signals to be acquired in the PC and analyzed. The developed software is concerned with first, the acquisition and processing of both ECG and PPG signals then the determination of the PWV and finally its analysis for different subjects and conditions. The analysis of the PWV is carried out for subjects of different ages in different physiological conditions according to heart activity. The obtained results show that there is a high correlation ([Formula: see text]), between heart rate variability (HRV) and PWV. They also show that PWV increases with age. The analysis of the PWV variations with age is also carried out through different regression models. The obtained result shows that the cubic regression model best fits these variations.

Border Effects, Fairness, and Phase Transition in Large Wireless Networks (2008)

We characterize the fairness of decentralized medium access control protocols based on CSMA/CA, such as IEEE 802.11, in large multi-hop wireless networks. In particular, we show that the widely observed unfairness of the protocol in small network topologies does not always persist in large topologies. This unfairness is essentially due to the unfair advantage of nodes at the border of the network, which have a restricted neighborhood and thus a higher probability to access the communication channel. In large one-dimensional networks these border effects do not propagate inside the network, and nodes sufficiently far away from the border have equal access to the channel; as a result the protocol is long-term fair. In two-dimensional networks, we observe a phase transition. If the access intensity of the protocol is small, the border effects remain local and the protocol behaves similarly as in one- dimensional networks. However, if the access intensity of the protocol is large enough, the border effects persist independently of the size of the network and the protocol is strongly unfair. Finally, in situations where the protocol is long-term fair, we provide a characterization of its short-term fairness.
Salt loading decreases intraday cardiac variability in dogs (1984)

The objectives of the conference were to assess the state of science regarding the relationships among stress, reactivity, and cardiovascular diseases; to evaluate the theoretical and conceptual bases of work in the area; and to identify the most pertinent variables to be studied, including the physiological indices of reactivity, types of stressors which induce reactivity, and the mediators and modifiers of stress-induced reactivity.To accomplish these objectives, all the participants reviewed relevant articles (numbering over 1,000 journal pages) prior to the conference, attended plenary sessions and developed recommendations in small task groups throughout the 3-day meeting.During the first working session of the task groups, the conferees discussed the theoretical issues, rationale, and measurement strategies regarding stressors and reactivity in six areas: 1) hemodynamic and electrophysiological measures of reactivity, led by Neil Schneiderman and Thomas Pickering; 2) biochemical measures of reactivity, led by Robert McDonald and David Goldstein; 3) psychological markers and correlates of reactivity, led by B. Kent Houston and Craig Ewart; 4) demographic and familial markers and correlates of reactivity, led by Laurence Watkins and Richard Rose; 5) environmental elicitors of reactivity primarily physical in nature, led by James Buell and Wallace McCrory; and 6) environmental elicitors of reactivity primarily psychological in nature, led by David Krantz and Rena Wing.During the next set of task group sessions, the conferees reviewed and evaluated the theoretical issues, potential mechanisms of action, and
Abstract 5018: Combination immunotherapy with PD-L1 blockade and Poly I:C in a murine breast cancer model (2014)

Abstract Background: Programmed death ligand 1 (PDL1) is commonly expressed on the surface of many tumor cells, including breast cancer. The activity of tumor infiltrating lymphocytes (TIL) is inhibited by PDL1. Blocking PDL1 with monoclonal antibodies can prevent this immune suppression and enhance anti-tumor activity. Polyinosinic-polycytidylic acid (Poly I:C) is a Toll like receptor 3 (TLR3) agonist which was shown to synergize with anti-PDL1 antibodies in a B16 melanoma model (Celis et. al, Blood 2010). We sought to investigate if synergy could be demonstrated in a murine breast cancer model. Methods: Five week old female BALB/c mice were injected with 3x106 4T1 cells in a mammary fat pad and divided into 4 groups with ten mice/group (PBS control, 200µg anti-PDL1 antibody (10F.9G2 Bioxcell) D1,5 IP, 50µg Poly I:C (Invivogen) D1,6,11,16 IV, anti-PDL1+Poly I:C). Treatment started when tumors were palpable and measured twice weekly. The mice were sacrificed 20 days later with tumors, spleens, and lymph nodes harvested. Tumors were measured twice weekly. All experiments were carried out under approved IACUC #4277R per institutional guidelines. Statistical analysis performed using Prism Graphpad. Results: Mean tumor measurements (mm2) at day 20 for control=207.5, anti-PDL1=188.5, Poly I:C=182.6, anti-PDL1+Poly I:C=149.4. Two way ANOVA was statistically significant at p&lt;.0001. Mean tumor weight (gm) at day 20 of anti-PDL1+Poly I:C=.99 vs control=1.23 p=.002 using t test. Conclusions: The combination of anti-PDL1 and Poly I:C TLR3 agonist demonstrates improved anti-tumor activity against established 4T1 orthotopic murine breast tumors compared to control or either agent alone. Characterization of TIL infiltrates in tumor specimens and immune activation in harvested lymphocytes is ongoing and will be presented. This data provides preliminary evidence supporting continued investigation of the combination of PDL1 and Poly I:C immunotherapy for breast cancer. Citation Format: Hatem Soliman, Ashley R. Nelson.
