Some classes of Hadamard matrices with constant diagonal (1972)

The concepts of circulant and backcirculant matrices are generalized to obtain incidence matrices of subsets of finite additive abelian groups. These results are then used to show the existence of skew-Hadamard matrices of order 8(4 f +1) when f is odd and 8 f + 1 is a prime power. This shows the existence of skew-Hadamard matrices of orders 296, 592, 1184, 1640, 2280, 2368 which were previously unknown. A construction is given for regular symmetric Hadamard matrices with constant diagonal of order 4(2m + 1) 2 when a symmetric conference matrix of order 4m + 2 exists and there are Szekeres difference sets, X and Y , of size m satisfying x є X ⇒ −xє X, y є Y ⇒ −y єY.
An adaptive lung ventilation controller (1994)

Closed loop control of ventilation is traditionally based on end-tidal or mean expired CO2. The controlled variables are the respiratory rate RR and the tidal volume VT. Neither patient size or lung mechanics were considered in previous approaches. Also the modes were not suitable for spontaneously breathing subjects. This report presents a new approach to closed loop controlled ventilation, called Adaptive Lung Ventilation (ALV). ALV is based on a pressure controlled ventilation mode suitable for paralyzed, as well as spontaneously breathing, subjects. The clinician enters a desired gross alveolar ventilation (V'gA in l/min), and the ALV controller tries to achieve this goal by automatic adjustment of mechanical rate and inspiratory pressure level. The adjustments are based on measurements of the patient's lung mechanics and series dead space. The ALV controller was tested on a physical lung model with adjustable mechanical properties. Three different lung pathologies were simulated on the lung model to test the controller for rise time (T90), overshoot (Ym), and steady state performance (delta max). The pathologies corresponded to restrictive lung disease (similar to ARDS), a "normal" lung, and obstructive lung disease (such as asthma). Furthermore, feasibility tests were done in 6 patients undergoing surgical procedures in total intravenous anesthesia. In the model studies, the controller responded to step changes between 48 seconds and 81 seconds. It did exhibit an overshoot between 5.5% and 7.9% of the setpoint after the step change.(ABSTRACT TRUNCATED AT 250 WORDS)
The fast algorithm of spark in compressive sensing (2017)

Compressed Sensing (CS) is an advanced theory on signal sampling and reconstruction. In CS theory, the reconstruction condition of signal is an important theory problem, and spark is a good index to study this problem. But the computation of spark is NP hard. In this paper, we study the problem of computing spark. For some special matrixes, for example, the Gaussian random matrix and 0-1 random matrix, we obtain some conclusions. Furthermore, for Gaussian random matrix with fewer rows than columns, we prove that its spark equals to the number of its rows plus one with probability 1. For general matrix, two methods are given to compute its spark. One is the method of directly searching and the other is the method of dual-tree searching. By simulating 24 Gaussian random matrixes and 18 0-1 random matrixes, we tested the computation time of these two methods. Numerical results showed that the dual-tree searching method had higher efficiency than directly searching, especially for those matrixes which has as much as rows and columns.
Relationship between emotional intelligence and conflict management styles of MBA faculty members: A correlational study (2012)

Much has been talked about emotional intelligence (EI) in the present millennium and its importance in different walks of life. This study was done to find out the relationship between EI and conflict management styles of MBA faculty members of 9 engineering colleges located in Bangalore South, affiliated to Visesvesvaraya Technological University, Belgaum, Karnataka. The sample consisted of 83 faculty members. The most preferred conflict management style used by faculty members in three classroom conflict situations were found out. The relationship between EI and conflict management styles was found out by correlation analysis. The data analysis revealed significant positive correlation between EI and collaborating style and negative correlation between EI and avoiding style in all the conflict situations addressed. The results also revealed insignificant relationship between EI and compromising style and accommodating style in the classroom conflict situations addressed in the study.
Electrodeposition of Au-Sn Alloys from a Modified Non-Cyanide Bath (2009)

This work presents improved Au-Sn baths to obtain a potentiostatically deposited Au-Sn alloys, by preventing bath degradation during the electrochemical process. Au-Sn bath speciation was studied through a program for chemical equilibrium simulation (CHEAQS Pro). The electrochemical reactions were investigated using Cyclic Voltammetry (CV). Rutherford Backscattering Spectroscopy (RBS) was used to determine the deposits composition. The results indicated that the best bath composition was KAuCl4 (5 g l-1), SnCl2×2 H2O (5 g l-1), ammonium citrate (150 g l-1), l-ascorbic acid (7.5 g l-1) and sodium sulfite (60 g l-1) to obtain an alloy with 16 at.% Sn. The best potential was defined as -600 mV, due to the largest thickness obtained.

Comparison of electrodeposited and sputtered intrinsic and aluminium-doped zinc oxide thin films (2008)

Intrinsic zinc oxide (i-ZnO) and aluminium-doped ZnO (ZnO:Al) are components of high-efficiency copper indium gallium diselenide solar cells. This paper examines both of these materials grown by two different techniques, namely radio frequency sputtering and electrodeposition (ED) for comparison and a better understanding. X-ray diffraction showed all materials to be polycrystalline and hexagonal (wurtzite) ZnO. Scanning electron microscopy indicated crystallites with different orientations for ED materials compared to agglomerated nanocrystallites of the sputtered layers. The band-gap energy was determined to be in the range 3.27-3.45 eV. The transmission was 85% for both ED materials and 95% for the sputtered layers. Glass/FTO/i-ZnO/Al structures were rectifying, and glass/FTO/ZnO:Al/Al contacts were ohmic for both ZnO:Al layers. Addition of Al decreases the bulk resistivity for both i-ZnO layers by 1-2 orders of magnitude. The photovoltage response to pulsed illumination showed a slow relaxation hysteresis, and all materials showed n-type electrical conduction.
Proteins associated with the cell envelope of Trichoderma reesei: A proteomic approach (2001)

A total of 220 cell envelope-associated proteins were successfully extracted and separated from Trichoderma reesei mycelia actively synthesizing and secreting proteins and from mycelia in which the secretion of proteins are low. Altogether 56 spots were examined by nanoelectrospray tandem mass spectrometry and amino acid sequence was obtained for 32 spots. From these, 20 spots were identified by Advanced BLAST searches against all databases available to BLAST. The most abundant protein in both types of mycelia was HEX1, the major protein in Woronin body, a structure unique to filamentous fungi. Other proteins identified were vacuolar protease A, enolase, glyceraldehyde-3-phosphate dehydrogenase, transaldolase, protein disulfide isomerase, mitochondrial outer membrane porin, diphosphate kinase and translation elongation factor beta. Partial short amino acid sequence obtained from some proteins did not allow them to be assigned to a specific protein in the database by BLAST search. In some cases, the tandem mass spectrometry spectra were too complicated to be able to assign an amino acid sequence with certainty. The number of spots (12) giving a clear signal but finding no match in the databases suggests that a majority of proteins associated with a filamentous fungal cell wall, are novel. Some technical problems related to protein isolation are also discussed.
Facile Preparation of Polyfluoroalkylated Aldimines from Polyfluoroalkanoic Acids (2007)

Randomized Phase III Trial of Vinorelbine Plus Cisplatin Compared With Observation in Completely Resected Stage IB and II Non–Small-Cell Lung Cancer: Updated Survival Analysis of JBR-10 (2009)

PURPOSE Adjuvant cisplatin-based chemotherapy (ACT) is now an accepted standard for completely resected stage II and III A non-small-cell lung cancer (NSCLC). Long-term follow-up is important to document persistent benefit and late toxicity. We report here updated overall survival (OS) and disease-specific survival (DSS) data. PATIENTS AND METHODS Patients with completely resected stage IB (T2N0, n = 219) or II (T1-2N1, n = 263) NSCLC were randomly assigned to receive 4 cycles of vinorelbine/cisplatin or observation. All efficacy analyses were performed on an intention-to-treat basis. Results Median follow-up was 9.3 years (range, 5.8 to 13.8; 33 lost to follow-up); there were 271 deaths in 482 randomly assigned patients. ACT continues to show a benefit (hazard ratio [HR], 0.78; 95% CI, 0.61 to 0.99; P = .04). There was a trend for interaction with disease stage (P = .09; HR for stage II, 0.68; 95% CI, 0.5 to 0.92; P = .01; stage IB, HR, 1.03; 95% CI, 0.7 to 1.52; P = .87). ACT resulted in significantly prolonged DSS (HR, 0.73; 95% CI, 0.55 to 0.97; P = .03). Observation was associated with significantly higher risk of death from lung cancer (P = .02), with no difference in rates of death from other causes or second primary malignancies between the arms. CONCLUSION Prolonged follow-up of patients from the JBR.10 trial continues to show a benefit in survival for adjuvant chemotherapy. This benefit appears to be confined to N1 patients. There was no increase in death from other causes in the chemotherapy arm.
A recurrent neural network for short-term load forecasting (2002)

This paper proposes a recurrent neural network based approach to short-term load forecasting in power systems. Recurrent neural networks in multilayer perceptrons have an advantage that the context layer is able to cope with historical data. As a result, it is expected that recurrent neural networks give better solutions than the conventional feedforward multilayer perceptrons in term of accuracy. Also, the differential equation form of the time series is utilized to deal with the nonstationarity of the daily load time series. Furthermore, this paper proposes the diffusion learning method for determining weights between units in a recurrent network. The method is capable of escaping from local minima with stochastic noise. A comparison is made between conventional multilayer perceptrons and the proposed method for actual data.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A 60-Mbaud single-chip QAM processor for the complete base-band signal processing of QAM demodulators (2002)

A QAM processor for applications in QAM demodulators with baud rates of up to 60 Mbaud and modulation schemes of up to 1024 QAM has been implemented on a single chip. Besides 11-tap complex-valued adaptive time-domain equalization, the chip performs the complete digital base-band signal processing of high-capacity QAM demodulators including frequency-domain slope equalization and the digital parts of the timing and carrier recovery as well as the gain and offset control for the A-to-D converters. The equalizer can be operated in baud spaced and half-baud spaced mode and can also be used for cross-polarisation interference cancellation. The computational power of the QAM processor exceeds 5 giga-multiply-accumulate operations per second. Fabricated in a 1.0-/spl mu/m CMOS technology on a silicon area of 185 mm/sup 2/ the 800 K-transistor chip demonstrates the potential of such economical technologies. The maximum clock frequency under worst-case conditions is 60 MHz, the corresponding power dissipation is 4.2 W.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Theoretical Study of Acceptor–Donor Complexes in 4H-SiC (2008)

The total energies and electronic structures of acceptor–donor complexes in 4H-SiC were investigated using ab initio calculation methods. Our calculations covered the A2D complex consisting of substitutional two-acceptor atoms from group-III elements and a nitrogen (N) donor atom. Results indicate some A2D complexes can exist stably, and solid solubilities of Al2N and Ga2N may be greatly enhanced. We also found that Ga2N introduces a shallower acceptor level compared to conventional acceptor atoms such as B and Al. Our results suggest that Ga+/N+ co-implantation is one of the promising candidates for a doping method to realize low-resistivity p-type 4H-SiC.
Comparison of Discovery Service Architectures for the Internet of Things (2010)

In the emerging Internet of Things rich data on real-world objects and events will be generated in vast amounts and stored in widely distributed databases. In truly global and dynamic application scenarios, intermediate brokers are needed to find these data, even if the exact location and form of storage are initially unknown to the requester. Discovery Services are aimed to fill this gap: they respond to requests for data on specific objects with a list of corresponding data providers. In this paper, we frame functional requirements for Discovery Services, and perform an overview and analysis of five established approaches for implementing Discovery Services that are taken from literature and industrial practice. In order to compare their characteristics, we develop a quality framework based on literature review and an ISO standard for software quality.
Activating CD94:NKG2C and inhibitory CD94:NKG2A receptors are expressed by distinct subsets of committed CD8<sup>+</sup> TCR αβ lymphocytes (2004)

A subset of CD8(+) T cells express the natural killer cell receptors CD94:NKG2A or CD94:NKG2C. We found that although many CD8(+) T cells transcribe CD94 and NKG2C, expression of a functional CD94:NKG2C receptor is restricted to highly differentiated effector cells. CD94:NKG2A is expressed by a different subset consisting of CCR7(+) memory cells and CCR7(-) effector cells. Since NKG2A can only be induced on naive CD8(+) T cells while CD94(-) memory cells are refractory, it is likely that commitment to the CD94:NKG2A(+) subset occurs during the first encounter with antigen. CCR7(+)CD94:NKG2A(+) T cells recirculate through lymph nodes where upon activation, they produce large quantities of IFN-gamma. These cells occur as a separate CD94:NKG2A(+) T cell lineage with a distinct TCR repertoire that differs from that of the other CD8(+)CD94(-) T cells activated in situ.
Speed clustering of integrated circuits (2005)

Experimental data on 0.18 /spl mu/ test chips shows strong evidence of clustering of speeds of neighboring dies on a wafer. This clustering phenomenon is utilized to develop techniques for predicting the speed of a part from the speeds of three or more of its neighbors. On-chip processor monitors are used to further improve the prediction accuracy of these techniques. Experimental data demonstrates both the effectiveness of these prediction schemes and the possibility of applying of them to reduce the cost of speed binning.
Resurgence of Congenital Rubella Syndrome in the 1990s (1992)

<h3>Objective.</h3> —To assess previous missed opportunities for rubella screening and vaccination of women delivering infants with congenital rubella syndrome and to discuss prevention strategies. <h3>Design.</h3> —Descriptive analysis of data collected through interviews and review of medical records. <h3>Population Studied.</h3> —Twenty-one women who delivered infants with congenital rubella syndrome in four Southern California counties from January 1, 1990, through January 8, 1991. <h3>Results.</h3> —Twelve (57%) of the women had a total of 22 known missed opportunities for rubella screening or vaccination. Of the 22 missed opportunities, three (14%) were missed screenings at the time of marriage, two (9%) were missed screenings during previous pregnancies, five (23%) were missed screenings during induced abortions, and 12 (55%) were missed opportunities for vaccination postpartum or after induced abortions. Nine (43%) of the women had no known missed opportunities for rubella screening or vaccination. Of 12 women educated in California, only four (33%) were subject to the 1982 California school rubella immunization requirement. <h3>Conclusions.</h3> —Congenital rubella syndrome could have been prevented in more than half of the infants born to these women if missed opportunities for rubella testing and/or vaccination had not occurred. Because premarital rubella testing and school immunization requirements do not ensure that all women of childbearing age are immune to rubella, physicians and hospitals should establish procedures for postpartum rubella vaccination of susceptible women. Family planning and abortion clinics should implement routine rubella testing and follow-up vaccination of susceptible women. (JAMA. 1992;267:2616-2620)
A tunable EBG absorber for radio-frequency power imaging (2011)

Absorption characteristics of a tunable electromagnetic band-gap (EBG) absorber are analyzed, which is designed to capture 2d radio-frequency (RF) power distributions incident on the absorber surface. The EBG absorber has lumped resistors interconnecting the mushroom-type surface patches to absorb the incident RF power at the resonance frequency where the EBG structure exhibits a high-impedance feature. The absorbed RF power distribution is measured by directly detecting the amounts of RF power consumed by the individual resistors. Varactor diodes are inserted in parallel with the resistors for tuning the resonance frequency of narrowband absorption. The absorption characteristics at normal incidence are evaluated in detail based on an equivalent circuit model which exactly explains the frequency behavior of the surface impedance of the tunable EBG absorber observed in EM simulation. The small resistance existing in the varactor diode makes it difficult for the surface impedance to be matched with the incident wave impedance (i.e., for a high absorption to be achieved) over a wide range of resonance frequency. A means to improve the absorption performance of the tunable EBG absorber is examined.
Urethane Films— Transdermal Opportunities (1987)

For transdermal patches to function, the packaging material must not only prevent unwanted diffusion of the active ingredients, but also—in a seemingly contradictory fashion—permit controlled rates of penetration of the active ingredients through the skin side of the patch. Polyurethanes have a unique combination of properties includ ing good physical properties and an ability to transmit gas and vapor while acting as a barrier to liquids. These films can be produced with a broad range of controlled dif fusion rates. Urethanes can also be formulated to provide good biocompatibility and other needed features, such as solvent resistance and heat sealability. The result has been that urethanes have been used successfully for the production of several transdermal patches.
Gliomas: classification with MR imaging. (1990)

The findings at magnetic resonance (MR) imaging in a group of 36 pathologically verified supratentorial gliomas were analyzed and compared with the biopsy diagnoses (a) to determine whether MR imaging could be used to classify astrocytic-series tumors into a three-tiered system of low-grade astrocytoma, anaplastic astrocytoma, and glioblastoma multiforme; and (b) to evaluate MR imaging features that may aid in this classification. The MR characteristics evaluated were crossing of the midline, edema, tumor signal heterogeneity, hemorrhage, border definition, cyst formation or necrosis, and mass effect. The statistically significant MR characteristics (positive predictors) were mass effect (P = .0000) and cyst formation or necrosis (P = .0512). The MR accuracy rate approached that of neuropathologic diagnosis, which is subject to sampling errors. MR imaging may serve as an adjunct in case management when the clinical course and MR findings appear to be at odds with the neuropathologic diagnosis.
Expression and DNA methylation patterns of Tslc1 and Dal‐1 genes in hepatocellular carcinomas induced by <i>N</i>‐nitrosodiethylamine in rats (2007)

To assess the involvement of the TSLC cascade in hepatocarcinogenesis, we investigated the expression and DNA methylation patterns of the genes Tslc1 and Dal-1 in hepatocellular carcinomas (HCC) induced using N-nitrosodiethylamine (DEN) in rats. Six-week-old male F344 rats received a single intraperitoneal injection of DEN at a dose of 10 mg/kg body weight, followed by combined treatment with partial hepatectomy and colchicine to induce cell-cycle disturbance and a selection procedure consisting of 2-acetylaminofluorene and carbon tetrachloride. Total RNA was extracted from 10 HCC, and the expression levels of Tslc1 and Dal-1 were measured using semiquantitative reverse transcription-polymerase chain reaction (RT-PCR) analysis. Three of 10 HCC showed reduced expression of Tslc1, compared with normal liver tissues, but no changes in the expression level of Dal-1 were found. For DNA methylation analysis, bisulfite sequencing was performed. The 5' upstream region of Tslc1 was methylated in the three HCC in which its expression was reduced, but was unmethylated in normal liver tissue. Western blot analysis also revealed reduced expression of Tslc1 protein in the three HCC. These results suggest that alterations to the TSLC cascade might have a role in hepatocarcinogenesis using DEN in rats.
Control of Nucleation and Solidification Direction of Polycrystalline Silicon by Excimer Laser Irradiation (2000)

The nucleation site and solidification direction of polycrystalline silicon were controlled by excimer laser crystallization. The sidewall and the top of the amorphous silicon island, which includes a gradually narrowing region, were covered with a thick layer of polycrystalline silicon, and single-shot irradiation was performed from the back surface. The formation of only one nucleus was observed in a gradually narrowing region of width two times that of the lateral growth distance. Solidification from the nucleus toward a narrower width region was then effected in a region 2 µm in width and 3 µm in length. The growth mechanism is explained on the basis of the temperature gradient formed by the covering of the polycrystalline silicon and the gradually narrowing structure.
