Electrically driven gyroscopes for aircraft (1944)

GYROSCOPIC instruments are given a place of prominence on the instrument panels of military and commercial aircraft. They are among the “most used” of all the instruments and are necessary for blind flight since they serve as stable references in space when natural objects are not visible. This group consists of a gyro horizon, showing the attitude of the aircraft — that is, whether or not it is in level flight; a directional gyro, which shows departure from course; and a bank and turn indicator, indicating rate of turn.

Facilitating Non-collocated coexistence for WiFi and 4G wireless networks (2012)

In this paper, we discuss the problem of non-collocated coexistence of WiFi and 4G technologies such as WiMAX and LTE due to adjacent channel interference. The existing literature has many solutions and schemes to address the problem of shared channel coexistence and adjacent channel coexistence on multi-radio platforms. Results for Non-collocated coexistence in adjacent channels in wireless remain very scattered and few. Radio devices operating on Broadband Wireless Access (BWA) 4G wireless technologies like IEEE 802.16 (WiMAX) and LTE-A require very low noise floor. BWA spectrum allocations in 2.3 GHz and 2.5GHz have resulted in these networks to be very close to 2.4 GHz ISM band used by WiFi. We show, with measurements on our test-bed and from existing results, that the low-cost filters on WiFi devices are not very effective in controlling the out-of-band emissions to satisfy the low noise floor requirements of 4G. We propose schemes to mitigate the problem of adjacent channel interference by a time sharing mechanism across technologies by protecting packet receptions on both IEEE 802.11 and the IEEE 802.16 side. We demonstrate the effectiveness of our scheme to protect WiMAX packets by ensuring a controlled silence zone in the WiFi network using a test-bed. We also show that there is very limited adverse impact, due to the use of our scheme, on the system throughput of the non-collocated WiFi network operating in the adjacent channel.
Correlation of Measurements for Body Fat in Obese Children (2004)

Purpose:Measurement of body fat in obese children is useful not only in evaluating health hazard but also in establishing standards of treatment and evaluating the effectiveness of treatment. In the field of clinical and laboratory study, there are various methods with different reliability, propriety, convenience, and expenses. However, the practical value of these studies is limited in Korea, especially in the field of pediatrics, therefore we investigated the correlation of body fat measurement methods to establish the basis for the practical use in children. Methods:The study is based on the records of a total of 32 cases who visited the pediatric obesity clinics at Chung-Ang University Yong San Hospital from April 2003 to September 2003. We measured the height, weight, waist-hip ratio obesity degree and body mass index. Then we analyzed the correlation of these manual measurement data with the results of bioelectrical impedance analysis(BIA), Dual energy X-ray absorptiometry(DEXA). Results:The body mass index was correlated with the quantity of body fat(r=0.805, P=0.000), the ratio of body fat(r=0.437, P=0.012), and the ratio of abdominal fat(r=0.458, P=0.008) in DEXA. The obesity degree was correlated only with the ratio of body fat(r=0.358, P=0.044) in DEXA. The body composition measured by BIA and DEXA showed significant correlation with the quantity of body fat(r=0.953, P=0.000) and the ratio of body fat(r=0.578, P=0.001), but the ratios of abdominal fat were not correlated with each other. Conclusion:Body mass index is more accurate compared with obesity degree. In addition, BIA can be utilized competitively in screening of body fat, although it is limited in measuring localized fat distribution when compared with DEXA. (Korean J Pediatr 2004;47:485-490)
Phase Transitions in an Antiferroelectric Liquid Crystal TFMHPOBC (1991)

We studied phase transitions in an antiferroelectric liquid crystal TFMHPOBC (C 8 H 17 O-&benzf;-&benzf;-COO-&benzf;- * CH(CF 3 )C 6 H 13 ) by means of dielectric measurements and microscopic observations. Both a Goldstone mode and a soft mode were observed in the SmC * phase, but only a soft mode in the SmC A * phase. From the temperature dependence of the relaxational frequency, it was clarified that the ferroelectric mode tends to be soft even in the antiferroelectric phase transition. The unwinding process of the helical structure in the SmC A * phase was observed with a reflecting microscope. It was also found that all the transitions, i.e., SmA-SmC A * , SmA-SmC * and SmC * -SmC A * , are of the first order. We present the E(electric field)-T(temperature) phase diagram of the optically pure TFMHPOBC and the mixture of R- and S-enantiomers.

A dedicated bit-sliced data path cluster is generated by the system and the layouts can be further generated through the LAGER IV system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Peer-to-Peer Enclaves for Improving Network Defence (2013)

IntroductionCurrent approaches to network defence are limited in scale and speed by the limited availability of skilled human operators and the inability of these operators to share information and work at cyberspeeds. We believe that network defence can be scaled out and enhanced through timely sharing of relevant information about common threats that are reasonably expected
Multi-primitive hierarchical (MPH) stereo analysis (1994)

This paper develops and demonstrates a new computational framework for an accurate, robust, and efficient stereo approach. In multi-primitive hierarchical (MPH) computational model, stereo analysis is performed in multiple stages, incorporating multiple primitives, utilizing a hierarchical control strategy. The MPH stereo system consists of three integrated subsystems: region-based analysis module; linear edge segment-based analysis module; and edgel-based stereo analysis module. Results of stereo analysis at higher levels of the hierarchy are used for guidance at the lower levels. The MPH stereo system does not overly rely on one type of primitive and therefore will reliably work on a wide range of scenes. The MPH stereo analysis results in the generation of several disparity maps of multiple abstraction. Disparity maps generated at each level can be fused to obtain an accurate and fine resolution disparity map. The MPH approach also provides the capability to selectively analyze image regions with varying detail. This provides the means for adaptively extracting range information of only sufficient resolution. Thus, a stereo system that utilizes primitives of different abstraction and a multilevel hierarchical computational strategy will be superior to a single-level, single-primitive system. Extensive experimentation is carried out on a wide array of scenes of varying complexity from two application domains to systematically evaluate the validity and performance of the MPH framework. The MPH stereo system is able to analyze images in most cases with 85%/spl sim/100% matching accuracy in under a minute of processing time and yield depth values typically within /spl plusmn/2% of the actual depth.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
ULTRASONIC TESTING OF STRUCTURAL WELDS (1969)

DURING THE PAST FIVE YEARS BETHLEHEM STEEL CORPORATION HAS DEVELOPED AND APPLIED TECHNIQUES FOR THE ULTRASONIC TESTING OF BUTT WELDS WHICH PROVIDES AN ASSURANCE OF WELD QUALITY SIMILAR TO THAT ACHIEVED WITH RADIOGRAPHY. ALTHOUGH THERE ARE NO REVOLUTIONARY BREAKTHROUGHS INVOLVED, A NUMBER OF SIGNIFICANT INNOVATIONS PERMIT A MORE REPEATABLE WELD TEST THAT HAS PREVIOUSLY BEEN ACHIEVED WITH ULTRASONICS. THE BUREAU OF PUBLIC ROADS HAS COOPERATED WITH BETHLEHEM STEEL CORPORATION FOR SEVERAL YEARS IN THESE DEVELOPMENTS. THEY HAVE RECENTLY PUBLISHED A TRAINING TEXT AND HAVE PERMITTED THE USE OF THE METHOD IN A RECENT CIRCULAR MEMORANDUM. /AUTHOR/
Automated validation of operational flight programs (OFPs) and flight training simulators (2002)

Operational flight programs (OFPs) that run in the embedded computer systems (ECSs) in modern aircraft must undergo extensive and rigorous validation testing before they are released for flight. Similar validation testing is required for the highest fidelity flight training simulators to assure that they accurately represent the behavior of the actual aircraft. This validation process, today, is largely manual. Test engineers develop and execute the test procedures by hand an the avionics test station or flight simulator. Manual testing is very time intensive, prone to errors, difficult to repeat precisely, and requires highly qualified experts. The automated validation (AutoVal) tool suite, developed by the Avionics Logistics Branch at Wright Laboratory (WL/AAAF), offers an alternative approach to testing that addresses these problems. AutoVal performs real-time testing of OFP and flight simulator software by completely automating the actions of the test engineers. It utilizes a testing-oriented command language that features user-definable macros for tailoring commands to specific applications. AutoVal reads and interprets commands stored in files or entered interactively through a command-line interface. Test engineers can generate reusable command files that configure and initialize the simulation, control the simulation flight dynamics and avionics modes, verify test results, and automatically create test logs. The most recent AutoVal research has focused on two areas: citation of an AutoVal translator that will produce MIL-STD-1815A Ada source code; and development of a learning capability that will record a test engineers actions and generate AutoVal command files.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Backside Wear in Modern Total Knee Designs (2006)

Although modularity affords various options to the orthopedic surgeon, these benefits come at a price. The unintended bearing surface between the back surface of the tibial insert and the metallic tray results in micromotion leading to polyethylene wear debris. The objective of this study was to examine the backside wear of tibial inserts from three modern total knee designs with very different locking mechanisms: Insall-Burstein II (IB II), Optetrak, and Advance. A random sample of 71 inserts were obtained from our institution's retrieval collection and examined to assess the extent of wear, depth of wear, and wear damage modes. Patient records were also obtained to determine patient age, body mass index, length of implantation, and reason for revision. Modes of wear damage (abrasion, burnishing, scratching, delamination, third body debris, surface deformation, and pitting) were then scored in each zone from 0 to 3 (0 = 0%, 1 = 0-10%, 2 = 10-50%, and 3 = >50%). The depth of wear was subjectively identified as removal of manufacturing identification markings stamped onto the inferior surface of the polyethylene. Both Advance and IB II polyethylene inserts showed significantly higher scores for backside wear than the Optetrak inserts. All IB II and Advance implants showed evidence of backside wear, whereas 17% (5 out of 30) of the retrieved Optetrak implants had no observable wear. There were no significant differences when comparing the depth of wear score between designs. The locking mechanism greatly affects the propensity for wear and should be considered when choosing a knee implant system.
A minimum cost heterogeneous sensor network with a lifetime constraint (2004)

We consider a heterogeneous sensor network in which nodes are to be deployed over a unit area for the purpose of surveillance. An aircraft visits the area periodically and gathers data about the activity in the area from the sensor nodes. There are two types of nodes that are distributed over the area using two-dimensional homogeneous Poisson point processes; type 0 nodes with intensity (average number per unit area) /spl lambda//sub 0/ and battery energy E/sub 0/; and type 1 nodes with intensity /spl lambda//sub 1/ and battery energy E/sub 1/. Type 0 nodes do the sensing while type 1 nodes act as the cluster heads besides doing the sensing. Nodes use multihopping to communicate with their closest cluster heads. We determine them optimum node intensities (/spl lambda//sub 0/, /spl lambda//sub 1/) and node energies (E/sub 0/, E/sub 1/) that guarantee a lifetime of at least T units, while ensuring connectivity and coverage of the surveillance area with a high probability. We minimize the overall cost of the network under these constraints. Lifetime is defined as the number of successful data gathering trips (or cycles) that are possible until connectivity and/or coverage are lost. Conditions for a sharp cutoff are also taken into account, i.e., we ensure that almost all the nodes run out of energy at about the same time so that there is very little energy waste due to residual energy. We compare the results for random deployment with those of a grid deployment in which nodes are placed deterministically along grid points. We observe that in both cases /spl lambda//sub 1/ scales approximately as /spl radic/(/spl lambda//sub 0/). Our results can be directly extended to take into account unreliable nodes.
Primate Vocalization, Gesture, and the Evolution of Human Language (2008)

The performance of language is multimodal, not confined to speech. Review of monkey and ape communication demonstrates greater flexibility in the use of hands and body than for vocalization. Nonetheless, the gestural repertoire of any group of nonhuman primates is small compared with the vocabulary of any human language and thus, presumably, of the transitional form called protolanguage. We argue that it was the coupling of gestural communication with enhanced capacities for imitation that made possible the emergence of protosign to provide essential scaffolding for protospeech in the evolution of protolanguage. Similarly, we argue against a direct evolutionary path from nonhuman primate vocalization to human speech. The analysis refines aspects of the mirror system hypothesis on the role of the primate brain's mirror system for manual action in evolution of the human language-ready brain.
A compact, planar, eight-port waveguide power divider/combiner: the cross potent superhybrid (2000)

We present a novel four-way divider/combiner in rectangular waveguide. The design is completely two-dimensional (2-D) in the h-plane, with eight-fold mirror symmetry, and is based on a recent four-port hybrid design. In combining mode, it can function as a phased array with four inputs and four outputs. The planar nature of this design provides advantages, such as the freedom to increase the waveguide height beyond the over-moding limit in order to reduce field strengths. Along with its open geometry, this makes it ideal for high-power applications where RF breakdown is a concern. Design criteria, field-solver simulation results, and prototype measurements are presented.
Preparation of Excipient-Free Recombinant Human Tissue-Type Plasminogen Activator by Lyophilization from Ammonium Bicarbonate Solution: An Investigation of the Two-Stage Sublimation Phenomenon (1997)

Dry, excipient-free recombinant human tissue-type plasminogen activator (tPA) powder was prepared by lyophilization from ammonium bicarbonate solution. Ammonium bicarbonate sublimes into ammonia, water, and carbon dioxide upon lyophilization, without causing measurable harm to the protein. There were approximately 4 mol of residual ammonium ion per mole of lyophilized tPA. Under certain lyophilization conditions, a large pressure increase in the lyophilizer chamber occurred, presenting a pressure control problem. Microscopy and sublimation rate measurements on the frozen matrix revealed that ice sublimation occurred first, followed by the sublimation of ammonium bicarbonate. Analysis of the sectioned frozen matrix indicated that the bicarbonate salt was evenly distributed throughout the vial, suggesting that the delay of ammonium bicarbonate sublimation was not due to hindrance by ice. In the two-stage process, ice sublimation proceeded according to zero-order kinetics, whereas ammonium bicarbonate sublimation followed a grain-burning (2/ 3-order) model and was governed by a higher activation enthalpy. In most cases, the sublimation rate of ammonium bicarbonate in the presence of tPA was lower than that in the absence of the protein. Sublimation activation enthalpy for ammonium bicarbonate in the presence of tPA was 26.1 +/- 3.8 kcal/mol, which was approximately 10 kcal/mol greater than that for the tPA-free system. Consistent with a prediction from our kinetic modeling, a 6-h extension of primary drying enabled us to conduct lyophilization while maintaining pressure control.

Rapid and accurate identification of Staphylococcus species by tRNA intergenic spacer length polymorphism analysis (1997)

PCR-amplified tRNA gene (tDNA) intergenic spacer length polymorphism (tDNA-ILP) was analyzed for its ability to identify to the species level type strains (n = 18) and clinical isolates (n = 163) of staphylococci. Amplified products obtained by PCR with outwardly directed consensus tDNA primers were separated by agarose and polyacrylamide gel electrophoreses. The results were compared with those obtained by biochemical identification and ribotyping. Each type strain presented a specific tDNA-ILP pattern. PCR with fluorescent primers allowed for the detection of labelled DNA fragments on polyacrylamide gels by using an automated laser fluorescence sequencer and provided enhanced pattern resolution in comparison with that by analysis on agarose gels. tDNA patterns indistinguishable from those of the type strains were produced by clinical isolates of all tested species except for some isolates of S. aureus (n = 3) and S. haemolyticus (n = 1), which showed variant patterns. Strains of S. saprophyticus and S. xylosus showed very closely related profiles, and S. cohnii subspecies were indistinguishable. The identities obtained by tDNA-ILP analysis agreed with those obtained by the biochemical method to the species level for 99% (162 of 163) of the strains tested and to the subspecies level for 96% (156 of 163) of the strains tested. These results indicate that fluorescence-labelled PCR analysis of tDNA-ILP provides an accurate and rapid molecular method for the identification of human staphylococci.
Correction: Common Variants in MAGI2 Gene Are Associated with Increased Risk for Cognitive Impairment in Schizophrenic Patients (2012)

Schizophrenia is a complex psychiatric disorder characterized by positive symptoms, negative symptoms, and cognitive impairment. MAGI2, a relatively large gene (,1.5 Mbps) that maps to chromosome 7q21, is involved in recruitment of neurotransmitter receptors such as AMPA-and NMDA-type glutamate receptors. A genetic association study designed to evaluate the association between MAGI2 and cognitive performance or schizophrenia has not been conducted. In this casecontrol study, we examined the relationship of single nucleotide polymorphism (SNP) variations in MAGI2 and risk for schizophrenia in a large Japanese sample and explored the potential relationships between variations in MAGI2 and aspects of human cognitive function related to glutamate activity. Based on the result of first schizophrenia genome-wide association study in a Japanese population (JGWAS), we selected four independent SNPs and performed an association study using a large independent Japanese sample set (cases 1624, controls 1621). Wisconsin Card Sorting Test (WCST) was used to evaluate executive function in 114 cases and 91 controls. We found suggestive evidence for genetic association of common SNPs within MAGI2 locus and schizophrenia in Japanese population. Furthermore in terms of association between MAGI2 and cognitive performance, we observed that genotype effect of rs2190665 on WCST score was significant (p = 0.034) and rs4729938 trended toward significance (p = 0.08). In conclusion, although we could not detect strong genetic evidence for association of common variants in MAGI2 and increased schizophrenia risk in a Japanese population, these SNPs may increase risk of cognitive impairment in schizophrenic patients.
