Impact of stray field on the switching properties of perpendicular MTJ for scaled MRAM (2012)

For the first time, we show the stray field (Hs) from the pinned layer of perpendicular magnetic tunnel junctions (pMTJs) plays multiple important roles: its out-of-plane component degrades pinned layer stability of scaled MTJ, while its in-plane component assists spin-transfer torque switching. Through stray field engineering, one can retain its advantage, and minimized its detrimental effect. We also show that etching process plays a vital role in the stray-field engineering. Our pMTJ exhibits robust pinned layer performance, symmetrical R-H loop and balanced spin-torque switching current. The switching current of our pMTJ is ~60uA@20us for a 80nm diameter pMTJ.

A one dimensional systolic array for solving arbitrarily large least mean square problems (2003)

The design is presented of a one-dimensional systolic array for solving arbitrarily large least-mean-square problems involving QR decomposition and a triangular system of equations. The main characteristics of this array are maximization of array utilization, thus achieving a minimum global computation time, and low complexity of the resulting array, which can also be used in problems such as matrix-by-vector, matrix-by-matrix, and LU decomposition. Two systolic algorithms for QR decomposition have been designed. Their chained execution is shown.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Equilibrium cyclotrimerization of <i>n</i>‐butyraldehyde (1977)

Abstract n ‐Butyraldehyde was cyclotrimerized by using boron trifluoride etherate as an initiator at −10 to 25°C under various conditions, e.g., in methylene chloride, in toluene, and without adding solvent. An equilibrium between the monomer and its cyclic trimer was observed, the equilibrium constant being highly dependent on not only the reaction temperature and the kind of solvents, but also the initial monomer concentration. A consistent interpretation for the results was obtained by the thermodynamic treatment of the equilibrium system as a nonideal solution composed of the monomer, its cyclic trimer, and solvent, in consideration of the intermolecular interactions between any two components.
Enterprise architecture for cloud-based ERP system development (2014)

The cloud computing concept is widely accepted as a new, influential method in the field of information technology. It offers ease of access, flexibility, security, etc. In recent years there are suggestions of making a large number of cloud-based applications; one of them is the enterprise resource planning (ERP). In general, making an ERP accessible through cloud computing offers great benefits regardless of what field may use them, but in order to achieve that level of operation some guidance and assessments are needed. There are numbers of companies who face failure in an attempt of using or even customizing ERP for their company. Enterprise architecture can be used to validate all necessary requirements a company needs to asses before implementing an ERP system, especially a cloud-based ERP system.
Effects of high concentrations of dietary vitamin e and ethoxyquin on the performance of laying hens1 (1991)

1. Three experiments were carried out with light strain laying hens to evaluate the effects of relatively high doses of dietary vitamin E (125 mg/kg food) or ethoxyquin (EQ) (250 mg/kg food) on their laying performance. The control diet contained 5 and 125 mg/kg vitamin E and EQ, respectively. The experimental diets were fed either from one or 32 weeks until 88 or 89 weeks of age. 2. The two antioxidants did not affect the growth of the pullets, age at first egg, final body weight, average egg weight or relative abdominal fat pad size and liver weight at the termination of the experiments. In two out of three experiments, vitamin E and EQ did not affect egg production, food efficiency or mortality; in the third experiment vitamin E significantly (P less than 0.05) improved egg production and food efficiency after an outbreak of Newcastle disease which occurred at 34 weeks of age. EQ significantly reduced mortality during the course of this experiment, but did affect the variables of performance. In two experiments vitamin E consistently improved shell density, although a significant effect was observed in only one of the eight determinations carried out. EQ did not affect this variable. 3. The uterine muscle was more susceptible to oxidation than the drumstick meat, as evaluated by TBA values. In both tissues, vitamin E significantly and consistently decreased TBA values and restricted their increase during incubation, while EQ was less effective, particularly in the drumstick meat. 4. It is concluded that increasing vitamin E and EQ concentrations in diets of laying hens have no effect on the decrease in egg production due to aging. However, vitamin E may minimize the decline in egg production and food efficiency following the outbreaks of some diseases and slightly improve--under certain yet undefined conditions--shell density.
Workload analysis and demand prediction for the HP ePrint Service (2013)

The proliferation of service oriented computing boosted by advances in cloud computing has led to design of new services that combine the power of both trends. The HP ePrint Service allows customers to print from anywhere to an HP ePrint-enabled printer accessible via the Internet. As ePrint is a hosted service, it must provide customers with a high quality of service while keeping the costs of supporting the load as low as possible. Understanding the load and the nature of this new service is crucial for properly designing the service's support infrastructure under rapidly growing user demand. With the complexity of services increasing and application requirements for QoS growing, the research challenge is to design an integrated framework of workload analysis combined with system measurement and modeling techniques that support performance analysis for the service. In this work, we present a detailed workload analysis of ePrint and a new performance tool for the automatic evaluation of required capacity for processing its diverse workload in a production environment while satisfying QoS requirements.

Modeling individual healthy behavior using home automation sensor data: Results from a field trial (2013)

A technical system for unobtrusive presence measurement and two novel models for describing user behavior in domestic environments are presented. Within the developed models user behavior is either described as the probability of being present at a certain location within an environment at a certain time on a day of the week or being present at a location for a certain number of times with a certain duration. The models are called timeslot-based and duration-based. Both models have been applied to presence information gathered by a technical system using home automation sensors. The system was installed into two flats of older people during a field trial for eight months. Results of the experiment show that the two models can be applied to describe individual user behavior. The influence of data structure and model quality on the detection of anomalies and the generation of alarms is discussed. On the long-term, the approach aims at detecting cutbacks in self-care ability and changes in health state by autonomously learning typical user behavior from presence information in a spatial model and by detecting untypical behavior, called anomalies, and generating alarms for caretakers. Such automatic assessment of self-care ability and health state is required in order to meet the increased challenges imposed to the decreasing number of care personal during the progress of the demographic change.
Attention-Aware Compositional Network for Person Re-identification (2018)

Person re-identification (ReID) is to identify pedestrians observed from different camera views based on visual appearance. It is a challenging task due to large pose variations, complex background clutters and severe occlusions. Recently, human pose estimation by predicting joint locations was largely improved in accuracy. It is reasonable to use pose estimation results for handling pose variations and background clutters, and such attempts have obtained great improvement in ReID performance. However, we argue that the pose information was not well utilized and hasn't yet been fully exploited for person ReID. In this work, we introduce a novel framework called Attention-Aware Compositional Network (AACN) for person ReID. AACN consists of two main components: Pose-guided Part Attention (PPA) and Attention-aware Feature Composition (AFC). PPA is learned and applied to mask out undesirable background features in pedestrian feature maps. Furthermore, pose-guided visibility scores are estimated for body parts to deal with part occlusion in the proposed AFC module. Extensive experiments with ablation analysis show the effectiveness of our method, and state-of-the-art results are achieved on several public datasets, including Market-1501, CUHK03, CUHK01, SenseReID, CUHK03-NP and DukeMTMC-reID.
Human haptoglobin structure and function – a molecular modelling study (2008)

Hemoglobin is the most prominent protein in blood, transporting O(2) and facilitating reactive oxygen and nitrogen species detoxification. Hemoglobin metabolism leads to the release of extra-erythrocytic hemoglobin, with potentially severe consequences for health. Extra-erythrocytic hemoglobin is complexed to haptoglobin for clearance by tissue macrophages. The human gene for haptoglobin consists of three structural alleles: Hp1F, Hp1S and Hp2. The products of the Hp1F and Hp1S alleles differ by only one amino acid, whereas the Hp2 allele is the result of a fusion of the Hp1F and Hp1S alleles, is present only in humans and gives rise to a longer alpha-chain. Haptoglobin consists of a dimer of alphabeta-chains covalently linked by a disulphide bond between the Cys15 residue of each alpha-chain. However, the presence of the Hp1 and Hp2 alleles in humans gives rise to HPT1-1 dimers (covalently linked by Cys15 residues), HPT1-2 hetero-oligomers and HPT2-2 oligomers. In fact, the HPT2 variant displays two free Cys residues (Cys15 and Cys74) whose participation in intermolecular disulphide bonds gives rise to higher-order covalent multimers. Here, the complete modelling of both haptoglobin variants, together with their basic quaternary structure arrangements (i.e. HPT1 dimer and HPT2 trimer), is reported. The structural details of the models, which represent the first complete view of the molecular details of human haptoglobin variants, are discussed in relation to the known haptoglobin function(s).
X-ray and Raman analyses of GaN produced by ultrahigh-rate magnetron sputter epitaxy (2002)

Thick films of GaN were studied by x-ray diffraction and Raman spectroscopy. The GaN thick films were deposited on (0001) sapphire using ultrahigh-rate magnetron sputter epitaxy with typical growth rates as high as 10–60 μm/min. The width of the x-ray rocking curve from the (0002) reflection for the sample produced by this technique is ∼300 arcsec, which is unprecedented for GaN produced by a sputtering-type process. Our recent sample shows an x-ray rocking curve width of 240 arcsec. Only allowed modes were observed in the polarized Raman spectra. The background free carrier concentration is lower than 3×1016 cm−3. The phonon lifetime of the Raman E2(2) mode of the sputtered GaN was comparable to that of bulk single crystal GaN grown by sublimation. The quality of the film was uniform across the wafer. The film was thermally stable upon annealing in N2 ambient. The x-ray and Raman analyses revealed that the sputtered GaN films are of high crystalline quality.
Induction of a calcium/calmodulin-dependent phosphodiesterase during phytohemagglutinin-stimulated lymphocyte mitogenesis. (1990)

A calmodulin (CaM)-dependent phosphodiesterase activity that hydrolyzes both cGMP and cAMP was observed in anion exchange high performance liquid chromatography (HPLC) profiles from phytohemagglutinin-stimulated mononuclear cells but not in profiles from unstimulated cells. A single polypeptide was detected by an antibody to the calmodulin-dependent phosphodiesterases on a Western blot of homogenates of stimulated mononuclear cells. The phosphodiesterase activity was immunoadsorbed in a calcium-dependent manner by an antibody to calmodulin but not by an antibody to the 61-kDa bovine brain phosphodiesterase. The mononuclear cell enzyme eluted from the HPLC column in the same fractions as the 63-kDa calmodulin-dependent isozyme from bovine brain and appeared to have the same subunit molecular weight when probed on a Western blot. The electrophoretic mobility of proteolytic fragments derived from the mononuclear cell phosphodiesterase were identical to those from the 63-kDa brain isozyme. The enzyme could be detected in mononuclear cells by activity assays and on a Western blot 14 h after stimulation with mitogen. The enzyme remained elevated for at least 100 h after stimulation. A dose-response experiment with phytohemagglutinin demonstrated that similar concentrations of mitogen could induce both mitogenesis and the phosphodiesterase. The induction of this enzyme requires mRNA as well as protein synthesis but not DNA synthesis. An enzyme similar to the 63-kDa phosphodiesterase found in brain seems to demonstrate a regulatory interface for the metabolism of calcium and cyclic nucleotides during lymphocyte mitogenesis.
Analysis of long-term survivors of glioblastoma multiforme in a single institution with aggressive local retreatment protocol. (2007)

When selecting patients on the basis of the factors associated with long-term survival, the same sequence of surgery, radiotherapy and chemotherapy that should be considered at first diagnosis might provide a moderate survival extension.
Design considerations and implementation of a DSP-based car-radio IF Processor (2004)

This paper describes design considerations and the implementation of a software defined radio receiver encompassing intermediate frequency (IF) digitization. The proposed system-on-chip performs the demodulation of both AM and FM stereo signals, digitized at the IF by means of a high dynamic range sigma-delta bandpass A/D converter. The chosen architecture combines hardware and software functions, trading flexible programmability with area occupancy. The software includes also true blind equalization of the FM signals, resulting in the rejection of the neighbor channels and of any other interfering signal, even under severe multipath conditions. The described chip, realized in a 0.18-/spl mu/m CMOS technology, occupies an area of 15.2 mm/sup 2/ and is enclosed in a 64-pin package.
Effect of Oral Glutamine Supplementation During Bone Marrow Transplantation (2000)

This study does not support the hypothesis that oral glutamine may offer benefit. Further investigation is required regarding clinical tools for determining effectiveness, administration for tolerance and compliance, dosage, and potential of oral glutamine usage.
Vehicle location in angular sectors based on signal strength (1978)

The results of field measurements carried out in center city Philadelphia and in the Whippany/Morristown, NJ suburban area to assess the accuracy of a vehicle location technique at 820 MHz based on signal strength comparison are described. Six co-sited directional antennas, each covering a 60° angular sector in azimuth, were used to detect the signal transmitted by the mobile. The angular location of the vehicle was determined by comparing the signal strengths received "simultaneously" through the directional antennas. The measured vehicle location was then compared against the true location of the vehicle at the time of the measurement to generate statistics on location accuracy. An estimate is made on the expected improvements in the locating accuracy when three co-sited directional antennas are used, each of which provides coverage for a 120° sector in the horizontal plane. Also described are the effects of signal sample "integration time" and antenna beam shaping on the accuracy of the position estimate. The measurement results presented put a bound on the expected range of accuracies in the signal-strength-based "angle-of-arrival" vehicle location technique.
Validation and usefullness of Indian version (CRD Pune) health assessment questionnaire: Drug trials, community practice and COPCORD Bhigwan population study (1994-2012) (2012)

Abstract Background Stanford HAQ (S-HAQ) and several versions are used worldwide to measure physical function. Based on traditions and life style, a maiden Indian version (CRD Pune) was developed and used extensively (1996–2011). We report clinimetric properties and long term use. Methods The Indian version was finalized in a step wise consensus building process between doctors, community and patients. It remained similar to S-HAQ in basic structure (categories) and score/disability index. Current data was selected from controlled drug trials in active RA, referral community patients (clinic and camps) and WHO ILAR COPCORD (community oriented program for control of rheumatic diseases) Bhigwan. Standard statistics were used; significant p  Results Test–retest and correlation statistics confirmed face and content (Cronbach's index >0.8) and construct validity and reliability at several time points. There was fair to good (0.2–0.6) correlation between Indian HAQ and pain visual analog scale, joint counts for pain/tenderness and swelling, sedimentation rate and radiological score (joint damage). The efficacy variables explained up to 70% variation in HAQ (dependent) regression models. The Indian HAQ scored significantly higher than the S-HAQ but the difference was not clinically relevant. The Indian HAQ was sensitive to change (effect size 0.7) over 24 week treatment with hydroxychloroquin. Generic use in COPCORD survey showed moderately severe HAQ disability in all patient groups including ‘ill-defined aches’ and soft tissue rheumatism. HAQ improved patient satisfaction. Conclusion The Indian HAQ (CRD Pune) was a valid and useful patient outcome measure and improved compliance (long term follow up).
Quality-of-Life Research on the Internet: Feasibility and Potential Biases in Patients with Ulcerative Colitis (1997)

It is feasible to conduct epidemiological research on the effects of UC on quality of life on the Web; however, systematic differences in disease activity between volunteer patients on the WWW and "in the clinic" may limit the applicability of results.
The Interrogation Footprint of RFID-UAV: Electromagnetic Modeling and Experimentations (2017)

The combined use of unmanned aerial vehicles (UAV) and radiofrequency identification (RFID) devices is an emerging topic of the environmental monitoring, which combines the versatility of multi-copter airframes with the potentiality of low-cost wireless sensors. This paper introduces some performance metrics suitable to quantify the capability of an RFIDrone to scan a surface equipped with radio-sensors. By using simple propagation models, an optimal drone-surface distance is mathematically derived at the purpose to maximize the electromagnetic footprint for the specific choice of system parameters, such as the sensor type and position, the reader sensitivity, the ground reflectivity, the radiated power, and the flight velocity. Theoretical achievements and some preliminary experimentations indicate that omnidirectional antennas are preferred for the drone so that 9–12 m footprints could be achieved with state-of-the-art readers and battery-less or battery-assisted RFID sensors, provided that the UAV flights at 3–5 m from the surface to be monitored. In this condition, the hit-rate of arrays of tags is better than 90% for a flying speed less than 1.8 km/h. The read performance is instead sensibly degraded by the presence of multi path in case of sensors spaced out the surface.

Covert channels in 802.11e wireless networks (2014)

WLANs (Wireless Local Area Networks) have been widely used in business, school and public areas. The newly deployed 802.11e protocol provides QoS in WLANs. However there are some vulnerability in it. This paper analyzed the 802.11e protocol for QoS support in WLANs and two new covert channels are proposed. These proposed covert channels provide signalling method in order to have reliable communication. The proposed covert channels have no impact on normal traffic pattern, thus it cannot be detected by monitoring traffic pattern.
Ionosphere Weighted GPS Cycle Ambiguity Resolution (2002)

Integer Ambiguity constraint is essential in precise GPS
positioning applications. The performance and reliability of
the ambiguity resolution process are being hampered by the
culmination of the eleven-year solar cycle. The traditional
approach to mitigate the high ionospheric effect has been
either to reduce the inter-station separation or to form
ionosphere-free observables. Neither is satisfactory: the first
restricts the operating range, and the second no longer
possesses the integerness of the ambiguities. A third
generalised approach is introduced herein, whereby the zero
ionosphere weight constraint, or pseudo-observable, with an
appropriate weight is added to the Kalman Filter algorithm.
The weight can be tightly fixed yielding the model
equivalence of an independent L1/L2 dual-band model. At
the other extreme, an infinite floated weight gives the
equivalence of an ionosphere-free model, yet preserves the
ambiguity integerness. A stochastically tuned, or weighted,
model provides a compromise between the two extremes.
Two days of selected Swedish GPS Network data sets from
ionospherically active (up to 15 ppm) and moderate (up to 4
ppm) days, forming baselines up to 400 km, have been analysed. The ionosphere weight model yielded a 90%
range of correct widelane ambiguities within three minutes,
regardless of inter-station distance.
