Quinoxalines Incorporating Triarylamines: Dipolar Electroluminescent Materials with Tunable Emission Characteristics (2006)

Abstract Dipolar compounds (abbreviated as QuPy ) featuring quinoxaline acceptors and diarylamine or triarylamine donors were prepared via palladium‐catalyzed C‐N or C‐C bond formation in good yields. They possess high thermal stability with a high decomposition temperature ( T d > 400 °C) and exhibit no crystalline character. The emission colors of the materials vary from green to orange red and are dependent on the nature of the electron‐withdrawing segments and solvents. Two types of double‐layer organic light‐emitting diodes (OLEDs) were constructed using these dipolar compounds as hole‐transporting/emitting layers and TPBI or Alq 3 as an electron‐transporting layer: (I) ITO/ QuPy /Alq 3 /Mg: Ag and (II) ITO/ QuPy /TPBI/Mg: Ag (TPBI = 1,3,5‐tris(N‐phenylbenzimidazol‐2‐yl)‐benzen; Alq 3 = 1,3,5‐tris(N‐phenyl‐benzimidazol‐2‐yl)‐benzene). The recombination zone in most of those devices were confined in the quinoxaline layers. The green to orange colors in these devices correspond well with the film PL of the material used. The relation between the energy levels of the compounds and the performance of the light‐emitting diode are discussed.
BaMO<sub>3</sub>(M=Zr, Hf, Sn) material dependence of<i>T<sub>c</sub></i>reduction in BaMO<sub>3</sub>-doped SmBa<sub>2</sub>Cu<sub>3</sub>O<sub><i>y</i></sub>, films (2014)

For the improvement of superconducting properties of BaMO3 (M=Zr, Sn, HQ-doped REBa2Cu3Oy films, we focused on the Tc reduction caused by lattice misfit between BaMO3 and REBa2Cu3Oy. We compared the influence on the Tc reduction of BaZrO3, BaSnO3 and BaHfO3-doped SmBa2Cu3Or (SmBCO) films with various BMO contents. From the correlation between configuration of nanorods and c-axis expansion, it was suggested that the lattice strain working on the SmBCO matrix became stronger in the order of BaHfO3, BaZrO3 and BaSnO3. Therefore, the combination of SmBCO and BaHfO3 is better regarding the suppression of the Tc reduction compared with other combinations of SmBCO and BaMO3.
Grids or air gaps for scatter reduction in digital radiography: A model calculation (1992)

The relative advantages of grids and air gaps for scatter reduction in a digital radiography system were investigated using a theoretical model. In this model the properties of the scatter reduction device are described by primary transmission and selectivity. The signal-to-noise (SNR) improvement factor for fixed exposure to the patient was used as a performance indicator. The results show that the SNR improvement depends strongly on the local scatter fraction; for all practical configurations, however, it stays below a factor of 2. For high scatter fractions, an air gap of 20 cm has about the same effect on SNR improvement as a highly selective grid; for low and medium scatter conditions the air gap performs better than any grid. Additive system noise reduces the SNR improvement factor compared to the case with quantum noise only, the reduction being more pronounced for the grids than for the air gap. The results suggest that the use of an air gap instead of a grid is advantageous in digital radiography systems.
Semantic Analysis for Keywords Based User Segmentation from Internet Data (2013)

Nowadays, Internet has been one of the major advertising channels and behavioral targeting has become increasingly important for improving the click-through rate of online advertisements. One of the key research problems in behavioral targeting is how to group users into segments with similar interests or backgrounds. In this paper, we propose a web page-oriented and keywords-based approach to address this problem. Our approach includes two key components: keyword similarity measurement and keyword similarity based user segmentation. These two components serve as plugins and can be replaced with better algorithms or measurements, making our approach very flexible. We have implemented the first key component, and provide preliminary results to illustrate the effectiveness of this component in finding similar news pages based on their keywords.
3D motion capture data: motion analysis and mapping to music (2002)

We report research performed on gesture analysis and mapping to music. Various movements were recorded using 3D optical motion capture. Using this system, we produced animations from movements/dance, and generate in parallel the soundtrack from the dancer&apos;s movements. Prior to the actual sound mapping process, we performed various motion analyses. We present here two methods, both independent of specific orientation or location of the subject. The first deals with gestural segmentation, while the second uses pattern recognition.
Adding type parameterization to the Java language (1997)

Although the Java programming language has achieved widespread acceptance, one feature that seems sorely missed is the ability to use type parameters (as in Ada generics, C++ templates, and ML polymorphic functions or data types) to allow a general concept to be instantiated to one or more specific types. In this paper, we propose parameterized classes and interfaces in which the type parameter may be constrained to either implement a given interface or extend a given class. This design allows the body of a parameterized class to refer to methods on objects of the parameter type, without introducing any new type relations into the language. We show that these Java extensions may be implemented by expanding parameterized classes at class load time, without any extension or modification to existing Java bytecode, verifier or bytecode interpreter.

Analytic response time model for distributed systems (1990)

Network designers are faced with a combinatorial explosion of choices not only among various vendors' workstations, hosts and servers, but also among application distribution strategies, communication media, communication protocols, and network topologies. To study performance trade-offs among various designs, the authors have developed a generic system thruput and response time model for distributed systems. We have applied the model to actual customer networks. The modeller describes the system in a language of model statements describing operations, resources, submodels, parameters and transactions flows. Model statements are “compiled” into arrays that form the input to the analytical queueing network model. The modeling package is written in APL2 and is based on an earlier VSAPL package developed for manufacturing planning. Since the package is designed with an open set of submodel types, and since APL2 is portable across many architectures and operating systems, we can easily integrate non-APL2 code.
Comparison of four state observer design algorithms for MIMO system (2013)

A state observer is a system that models a real system in order to provide an estimate of the internal state of the system. The design techniques and comparison of four different types of state observers are presented in this paper. The considered observers include Luenberger observer, Kalman observer, unknown input observer and sliding mode observer. The application of these observers to a Multiple Input Multiple Output (MIMO) DC servo motor model and the performance of observers is assessed. In order to evaluate the effectiveness of these schemes, the simulated results on the position of DC servo motor in terms of residuals including white noise disturbance and additive faults are compared.
Prevention of corticosteroid-induced osteonecrosis in rabbits by intra-bone marrow injection of autologous bone marrow cells (2008)

Direct injection of autologous BMCs into femurs prevents corticosteroid-induced ON following treatment with high-dose, short-term steroids.
Photonic crystal based resonant antenna with a very high directivity (2000)

We investigate the radiation properties of an antenna that was formed by a hybrid combination of a monopole radiation source and a cavity built around a dielectric layer-by-layer three-dimensional photonic crystal. We measured a maximum directivity of 310, and a power enhancement of 180 at the resonant frequency of the cavity. We observed that the antenna has a narrow bandwidth determined by the cavity, where the resonant frequency can be tuned within the band gap of the photonic crystal. The measured radiation patterns agree well with our theoretical results. © 2000 American Institute of Physics.
Identification of Poinsettia Cultivars Using RAPD Markers (1997)

Randomly amplified polymorphic DNA (RAPD) techniques were used to compare the DNA from leaf tissues of nine commercial poinsettia ( Euphorbia pulcherrima Wild ex Klotzsch) cultivars. Amplification occurred in 57 out of 60 (95%) tested primers. Nine primers that revealed polymorphisms among cultivars were selected for further evaluation. Forty-eight RAPD bands were scored from these primers, and 33 (69%) were polymorphic. All tested cultivars could be discriminated with seven bands generated from primers OPB7 and OPC13. Results of a UPGMA cluster analysis and principal components analysis placed the nine cultivars into two groups: one group consisted of `Jingle Bells', `Supjibi', and `V-17 Angelika', the other of `V-14 Glory', `Red Sails', `Jolly Red', and `Freedom'. `Lilo Red' and `Pink Peppermint' belonged to the latter group, but were relatively distant from other cultivars in that group. These results indicate that RAPDs are efficient for identification of poinsettia cultivars and for determination of the genetic relationships among cultivars.
Digital and RF interference cancellation for single-channel full-duplex transceiver using a single antenna (2013)

This paper presents a full-duplex transceiver system design operating with a single channel using a single antenna for both transmitting and receiving paths. To implement such a system, the self-interference is necessary to be eliminated. From literatures on RF interference cancellation, there has not been any suitable technique to deal with a single antenna. In this light, this work initially proposes the technique to cancel the self-interference by utilizing on-the-shelf components. The measurement results indicate that the proposed system can reduce the level of self-interference about 75 dB, which is better than others in literatures.
Analog baseband IC for use in direct conversion W-CDMA receivers (2002)

A 0.6 /spl mu/m BiCMOS analog baseband IC that enables a direct conversion W-CDMA receiver is described. Two diversity I/Q channels provide 87 dB of voltage gain, controllable in 1-dB steps. A 2 MHz low pass filter, synchronized to an external RC network, provides an accurate rejection mechanism against adjacent channel interference. A log amp provides a "Fast-RSSI" function for rapidly selecting gain settings. Low DC current (<5 mA/path), low input noise (<4 nV/Hz/sup 1/2/), and a high P3dB (-20 dBVrms) are achieved.
<sup>1</sup>H chemical shift magnetic resonance imaging probes with high sensitivity for multiplex imaging (2012)

Proton-based chemical shift imaging probes were encapsulated inside nano-carriers to increase the sensivitity of the reporters. Co-encapsulation with a relaxation agent results in improved sensitivity and suppresses background signals. Simultaneous imaging of different chemical shift reporters allows multiplexed detection.
Conflict free coordination of SON functions in a Unified Management Framework: Demonstration of a proof of concept prototyping platform (2013)

This paper proposes the exploitation of a Unified Management Framework for coordinating (i.e. ensuring conflict-free and stable operation), multiple, autonomic control loops. The functionality is demonstrated through the instantiation to Self-Organizing Network (SON) coordination for managing LTE-Advanced Heterogeneous Network (HetNet) with relays.
Silicon based light emitting gels (1996)

Light emitting properties of a silicon-containing gel formed by the controlled reaction between acetone and tetrachlorosilane is reported here. Although infrared spectroscopic analysis shows that the gel has a siloxane network (1000–1100 cm−1), UV absorption with a maximum of 328 nm suggests that it is not a simple siloxane polymer. A photoluminescence (PL) spectrum of the compound gives a broad peak in the range of 800–950 nm, attributed to the structural features associated with carbonyl conjugated siloxane groups.
Recognition of Distorted Patterns Using the Viterbi Algorithm (1982)

In this paper a new recognition system of distorted patterns is presented, where the Viterbi algorithm and a modified trellis incorporating a pertinent statistics of distorted patterns are used. The system works in a manner quite similar to our own human decision process. The trellis is so constructed that it can eliminate all the irrelevant pattern classes at the outset and leave only the most probable for its fimal decision, yielding a great economy of processing time and the accuracy of decision. The method was applied to recognition of handwritten English letters and Japanese Katakana's with success. The method is also universal and can be applied to any category of distorted pattems.
An Ultra-Wideband Horizontally Polarized Omnidirectional Circular Connected Vivaldi Antenna Array (2017)

An ultra-wideband horizontally polarized omnidirectional antenna is proposed. The connected Vivaldi antenna array mechanism is exploited to achieve the ultra-wide bandwidths of both the impedance and the radiation patterns simultaneously. Sixteen Vivaldi antenna elements are connected with each other and distributed along a circular substrate to form the proposed antenna. The designed antenna exhibits a relative impedance bandwidth of 159.97% (1.28-11.51 GHz) for |S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> | <; -10 dB. Meanwhile, uniform omnidirectional radiation patterns with a gain variation of less than 1.5 dB have been obtained within the frequency band of 1.25-7.6 GHz (142.73%).

Carbohydrate profiles shown by a lectin and a monoclonal antibody correlate with metastatic potential and prognosis of human lung carcinomas (1992)

The expression of two carbohydrate markers--namely, 4C9 antigen, which is an Lex antigen, and the Dolichos biflorus agglutinin (DBA) binding site, which is an N-acetylgalactosamine marker--was examined histochemically in tumors and adjacent nontumorous tissues of 102 cases of human lung carcinomas. In nontumorous tissues, the DBA binding site was expressed more frequently than 4C9 antigen, and the DBA binding site had a tendency to be expressed more significantly than in tumor cells. Adenocarcinomas and well-differentiated tumors had a tendency to more cell surface staining. Patients with tumors that expressed DBA binding sites but not 4C9 antigen (4C9-, DBA+) had fewer metastasis and significantly better prognoses than patients with tumors of other carbohydrate profiles. Better prognosis of patients with 4C9-, DBA+ tumors was observed in those with blood group A antigen and those without it, and the better prognosis also was observed in patients with Stage I and IIIA disease.
F-C3D: FPGA-based 3-dimensional convolutional neural network (2017)

In recent years, 3-dimension convolutional neural networks (3D CNNs) have been widely used for video analysis, 3-dimension geometric data and medical image diagnosis. While conventional CNNs are computationally intensive, 3D CNNs push the computational requirements into another level, since each computation depends on multiple image frames. This paper describes a novel hardware architecture for a 3D convolutional neural network, and design strategies to resolve memory usage and bandwidth limitations. The proposed architecture F-C3D is implemented on zc706 at 172MHz, showing 231 times speed up compared with software implementation on 1 GHz ARM CPU, 7.4 times speed up on 3.07 GHz Intel CPU and nearly 10 times lower power consumption than GPU.
Changes in strength of lung inflation reflex during prolonged inflation (1975)

Recovery from respiratory inhibition produced by the lung inflation reflex was studied in anesthetized dogs, paralyzed and ventilated with a respiratory pump. During constant ventilation the lungs were periodically inflated using positive end-expiratory pressure, while the respiratory motor output was monitored in the phrenic nerve. Inhibition of the phrenic discharge was followed by gradual recovery throughout 8-min inflation periods despite constant blood gases. Recording afferent potentials in a vagus nerve indicated that adaptation of pulmonary stretch receptors contributed to the initial recovery of the phrenic discharge, but this recovery continued after the receptor discharge had stabilized. The phrenic discharge also recovered after initial inhibition in two situations which avoided stretch receptor adaptation: a) when the stretch receptor discharge from the separate lungs was alternated in an overlapping manner by asynchronous pulmonary ventilation, and b) during continuous electrical stimulation of a vagus nerve. Phrenic activity was temporarily increased above its control value after periods of lung inflation, asynchronous ventilation and vagal stimulation. It is concluded that the lung inflation reflex gradually attenuates during prolonged stimulation due to both stretch receptor adaptation and changes within the central pathways.
Fiber-optic sensor for surface acoustic waves (1982)

Optical probing of acoustic waves provides a noncontacting method of making high-resolution measurements of the amplitude and phase of surface displacements associated with acoustic waves. Two probes have been developed for this purpose. The first uses both bulk and fiber components. It is a fiber-optic variation of the heterodyne interferometric probe used by De La Rue et al.1 Since long lengths of fiber can be placed between the laser and the sample without significant losses, large samples can be mechanically scanned with the probe head. The second probe uses an all-fiber approach. Consequently, this probe is considerably smaller and more rugged.
Augmented Reality for Assistance of Total Knee Replacement (2016)

The aim of this work was the development of a surgical assistance system based on augmented reality to support joint replacement procedures and implantation of prosthetic knee. Images of the scene were captured in order to detect the visual markers located on the lateral surface of the patient’s leg for overlapping the 3D models of the prosthesis and the joint, as well as the tool used by the medical specialist. With the marker identification, it was possible to compute its position and orientation for locating the virtual models, obtaining a monitoring system for giving accurate information about the procedure. Also it can be used as training platform for surgeons, without having volunteers or patients for performing real surgeries; instead they can train in a virtual environment. The results have shown an efficient system in terms of cost-benefit relation, taking into account the materials used for developing the system; nevertheless, the accuracy of the algorithm decreases according to the distance between the markers.
Overproduction and purification of Treponema pallidum recombinant-DNA-derived proteins TmpA and TmpB and their potential use in serodiagnosis of syphilis (1989)

We report the construction of expression plasmids carrying two Treponema pallidum genes encoding for the 42-kilodalton membrane protein TmpA (treponemal membrane protein A) and the 34-kilodalton membrane protein TmpB. Using the leftward promoter of bacteriophage lambda, which is controlled by a thermosensitive repressor, we obtained a high level of heat-inducible synthesis of TmpA and TmpB in Escherichia coli K-12. Both proteins were purified to near homogeneity, and the presence of antibodies to TmpA and TmpB in human sera was determined by an enzyme-linked immunosorbent assay. Whereas in all 44 serum samples from untreated patients in the secondary and early latent stages of syphilis, high levels of anti-TmpA antibodies were detected, only 34 serum samples contained anti-TmpB antibodies. As has been previously observed for TmpA, a correlation was found between the presence of anti-TmpB antibodies and anti-cardiolipin antibodies, suggesting that the level of antibodies to TmpB drops soon after successful antibiotic treatment. We concluded that, in contrast to TmpA, TmpB is not suitable for serodiagnostic purposes as a single antigen, because a significant fraction of sera from syphilitic patients was nonreactive with TmpB.
A Hierarchical Career-Path-Aware Neural Network for Job Mobility Prediction (2019)

The understanding of job mobility can benefit talent management operations in a number of ways, such as talent recruitment, talent development, and talent retention. While there is extensive literature showing the predictability of the organization-level job mobility patterns (e.g., in terms of the employee turnover rate), there are no effective solutions for supporting the understanding of job mobility at an individual level. To this end, in this paper, we propose a hierarchical career-path-aware neural network for learning individual-level job mobility. Specifically, we aim at answering two questions related to individuals in their career paths: 1) who will be the next employer? 2) how long will the individual work in the new position? Specifically, our model exploits a hierarchical neural network structure with embedded attention mechanism for characterizing the internal and external job mobility. Also, it takes personal profile information into consideration in the learning process. Finally, the extensive results on real-world data show that the proposed model can lead to significant improvements in prediction accuracy for the two aforementioned prediction problems. Moreover, we show that the above two questions are well addressed by our model with a certain level of interpretability. For the case studies, we provide data-driven evidence showing interesting patterns associated with various factors (e.g., job duration, firm type, etc.) in the job mobility prediction process.
Nanostructured nickel electrodes using the<i>Tobacco mosaic virus</i>for microbattery applications (2008)

The development of nanostructured nickel–zinc microbatteries utilizing the Tobacco mosaic virus (TMV) is presented in this paper. The TMV is a high aspect ratio cylindrical plant virus which has been used to increase the active electrode area in MEMS-fabricated batteries. Genetically modifying the virus to display multiple metal binding sites allows for electroless nickel deposition and self-assembly of these nanostructures onto gold surfaces. This work focuses on integrating the TMV deposition and coating process into standard MEMS fabrication techniques as well as characterizing nickel–zinc microbatteries based on this technology. Using a microfluidic packaging scheme, devices with and without TMV structures have been characterized. The TMV modified devices demonstrated charge–discharge operation up to 30 cycles reaching a capacity of 4.45 µAh cm−2 and exhibited a six-fold increase in capacity during the initial cycle compared to planar electrode geometries. The effect of the electrode gap has been investigated, and a two-fold increase in capacity is observed for an approximately equivalent decrease in electrode spacing.
