Compacting Behavior of Nd-Fe-B Magnet Powder in Rubber Isostatic Pressing. (1998)

The application of Nd-Fe-B sintered magnets to the electronic parts has been greatly progressed and Nd-Fe-B sintered magnets are demanded to possess further excellent magnetic properties. Recently, Rubber Isostatic Pressing(RIP) method have been developed to get the high magnetic performance. Since in RIP, powders of the magnet inside rubber die are pressed like the isostatic process, the orientations of C axis of the powders don't change. Therefore, the magnet made by RIP shows superb magnetic properties. But, the effects of the RIP process conditions on the compactibility have not been clear because of the complicated behaviors of powders of the magnet and the rubber die in magnetic field. From obtained results through this study, it has been proved that the problems of RIP method are the bad compactibility such as the occurrence of the cracking and marked deviation in outer dia. of the RIP green compact although Nd-Fe-B sintered magnets made by RIP showed excellent magnetic properties.
Maximizing the relaxivity of HSA-bound gadolinium complexes by simultaneous optimization of rotation and water exchange (2007)

Two new GdEGTA (EGTA = ethylene glycol-bis(2-aminoethylether)-N,N,N',N'-tetraacetic acid) derivatives incorporating aromatic moieties into the oxoethylenic bridge have been prepared and characterised, their conjugates to HSA investigated and an unprecedented high relaxivity, close to that predicted by theory, interpreted in terms of the combined effect of restricted local rotation and fast rate of water exchange.
Firewall Rulebase Management (2011)

The network firewall serves as one of the foundational network components for modern day computer security. A key challenge with respect to firewalls is the on-going maintenance of the rules of the various firewall devices, namely how does one keep the firewall at maximum security effectiveness in the face of changing security threats and enterprise application needs? To that end, this chapter focuses on contributions in two key areas with respect to the practice of firewall rulebase management. First, the chapter presents a general model for the auditing and analysis of installed firewalls that ensures compliance with security policy requirements and technical specifications. Second, the chapter provides insight for the proactive identification of rules that possess a high likelihood of becoming orphaned in the future based upon their similarity to previously orphaned firewall rules.
Adaptive OFDM for underwater acoustic channels with limited feedback (2011)

In this paper we analyze the performance of adaptive orthogonal frequency division multiplexing (OFDM) for underwater acoustic (UWA) communications. Our goal is to maximize the system throughput under a target average bit error rate (BER). We consider two different schemes based on the level of adaptivity: in the first scheme only the modulation levels are adjusted while the power is allocated uniformly across the sub-carriers, whereas in the second scheme, both the modulation levels and the power are adjusted adaptively. We exploit a feedback from the receiver in two forms: one that conveys the modulation alphabet and quantized power levels to be used for each sub-carrier, and another that conveys a quantized estimate of the sparse channel impulse response. We compare these two strategies based on the average number of bits per OFDM block needed to achieve a pre-specified target average BER. In both cases we predict the channel one travel time ahead so as to improve the performance in the presence of a long propagation delay. The second approach is shown to be advantageous, as it requires significantly fewer feedback bits for the same system throughput. The effectiveness of the proposed schemes is demonstrated using real channel measurements recorded in shallow water off the western coast of Kauai, Hawaii, in June 2008.
Translocation of a Store of Maternal Cytoplasmic c- myc Protein into Nuclei during Early Development (1989)

The c-myc proto-oncogene is expressed as a maternal protein during oogenesis in Xenopus laevis, namely, in nondividing cells. A delayed translation of c-myc mRNA accumulated in early oocytes results in the accumulation of the protein during late oogenesis. The oocyte c-myc protein is unusually stable and is located in the cytoplasm, contrasting with its features in somatic cells. A mature oocyte contains a maternal c-myc protein stockpile of 4 x 10(5) to 6 x 10(5) times the level in a somatic growing cell. This level of c-myc protein is preserved only during the cleavage stage of the embryo. Fertilization triggers its rapid migration into the nuclei of the cleaving embryo and a change in the phosphorylation state of the protein. The c-myc protein content per nucleus decreases exponentially during the cleavage stage until a stoichiometric titration by the embryonic nuclei is reached during a 0.5-h period at the midblastula stage. Most of the maternal c-myc store is degraded by the gastrula stage. These observations implicate the participation of c-myc in the events linked to early embryonic development and the midblastula transition.
Demonstration of a Novel Positron Source Based on a Plasma Wiggler (2006)

A new method for generating positrons has been proposed that uses betatron X‐rays emitted by an electron beam in a high‐K plasma wiggler. The plasma wiggler is an ion column produced by the head of the beam when the peak beam density exceeds the plasma density. The radial electric field of the beam blows out the plasma electrons transversely, creating an ion column. The focusing electric field of the ion column causes the beam electrons to execute betatron oscillations about the ion column axis. If the beam energy and the plasma density are high enough, these oscillations lead to synchrotron radiation in the 1–50 MeV range. A significant amount of electron energy can be lost to these radiated X‐ray photons. These photons strike a thin (.5Xo), high‐Z target and create e+/e− pairs. The experiment was performed at the Stanford Linear Accelerator Center (SLAC) where a 28.5 GeV electron beam with σr ≈ 10μm and σz ≈ 25μm was propagated through a neutral Lithium vapor (Li). The radial electric field of the dense beam was large enough to field ionize the Li vapor to form a plasma. The positron yield was measured as a function of plasma density, ion column length and electron beam pulse length. A computational model was written to match the experimental data with theory. The measured positron spectra are in excellent agreement with those expected from the calculated X‐ray spectral yield from the plasma wiggler. After matching the model with the experimental results, it was used to design a more efficient positron source, giving positron yields of 0.44 e+/e−, a number that is close to the target goal of 1–2 e+/e− for future positron sources.
Speed of Adoption of Immune Checkpoint Inhibitors of Programmed Cell Death 1 Protein and Comparison of Patient Ages in Clinical Practice vs Pivotal Clinical Trials (2018)

Anti-PD-1 agents rapidly reached patients in clinical practice, and patients treated in clinical practice differed significantly from patients treated in pivotal clinical trials. Future actions are needed to ensure that rapid adoption occurs on the basis of representative trial evidence.

Structural relationship between the 100,000- and 17,000- molecular-weight T antigens of simian virus 40 (SV40) as deduced by comparison with the SV40-specific proteins coded by the nondefective adenovirus type 2-SV40 hybrid viruses (1979)

The two-dimensional peptide maps of the methionine-containing tryptic peptides of the 100,000-molecular-weight (100K) and 17K T antigens of simian virus 40 (SV40) have been compared. The two proteins share nine methionine-containing tryptic peptides in common. The 17K T antigen has two peptides not found in the 100K T antigen, and the 100K T antigen has 14 unique peptides. The peptide maps of the 100 K and 17K T antigens were also compared with those of the SV40-specific proteins found in cells infected by the nondefective adenovirus type 2-SV40 hybrid viruses, which we have previously shown are encoded by defined sequences within the early region of SV40 (K. Mann, T. Hunter, G. Walter, and H.K. Linke, J. Virol. 24:151-169, 1977). This comparison shows that the 100K and 17K T antigens share common N-terminal sequences coded for between 0.65 and 0.59 map units on the SV40 genome. Furthermore, none of the sequences in the 17K T antigen arises from the region between 0.54 and 0.18 map units. We deduce that the sequences unique to the 17K T antigen originate between 0.59 and 0.54 map units. This type of structural relationship between the 100K and 17K T antigens fits well with the proposed model (L.V. Crawford, C.N. Cole, A. E. Smith, E. Paucha, P. Tegtmeyer, K. Rundell, and P. Berg, Proc. Natl. Acad. Sci. U.S.A. 75:117-121, 1978) for the expression of the early region of SV40.
BIRTHING THE INFORMATION INDUSTRY IN THE FORMER SOVIET UNION (1993)

In the course of my travels and discussions throughout the United States and Europe, it has become quite apparent that there is great interest in Russian business and sci‐tech data. The Russian Federation, other former republics and the countries of Central Europe are seen as a large potential market for western goods. There is great interest in Russian products and especially in resources such as oil and gas. These countries also have a large and well‐educated work‐force.
Fuzzy Logic in VANET context aware Congested Road and Automatic Crash Notification (2016)

For VANET safety services a context aware system for the Automatic Crash Notification (ACN) is developed while the context aware Congested Road Notification system (CRN) is developed for the convenience services. A simple fuzzy logic model is proposed and compared to different severity estimation models deployed for both systems. The performance of the ACN models is compared using a test collection that is based on nineteen years of real life crash records associated with their severity levels while the performance of the CRN models is tested using nearly 500,000 different urban and rural freeways flow situations associated with their congestion severity levels. The non-binary Spearman correlation coefficient and the Average Distance Measure (ADM) are used to evaluate the performance of the tested models. Results show that the simple fuzzy severity estimation model has a comparable performance to more complicated systems such as the CoTEC (CoOperative Traffic congestion detECtion) fuzzy system and the URGENCY algorithm, and outperforms the binary severity estimation models for the ACN and CRN systems.

Blood glucose individualized prediction for type 2 diabetes using iPhone application (2011)

Type 2 diabetes is now the most rapidly growing form of diabetes and has become increasingly common among children. This paper presents our work of implementing an individualized real time predictive system for blood glucose in type 2 diabetes in an iPhone application. The developed application, called HealthiManage, provides relevant feedback to patients at each glucose input reading comparing the measured and predicted readings, facilitating improved self-management of the disease. The application incorporates activity recognition via a built-in accelerometer on the iPhone, which monitors any physical activity and adjusts predictions accordingly. Also, a reward component interface was incorporated that is intended to enhance patient compliance and encourage mainly teenagers to take control and improve their blood glucose regulation. The individualized prediction algorithm was tested and verified with real patient data. Different physical activities were also examined and classified for an accurate activity recognition component. The designed application with its predictive model, activity recognition, and other elements provide what we believe to be helpful feedback to monitor and manage type 2 diabetes and improve patient compliance.
Bipolar and Unipolar Resistive Switching in Cu-Doped $ \hbox{SiO}_{2}$ (2007)

Scalable nonvolatile memory devices that operate at low voltage and current, exhibit multilevel cell capability, and can be read nondestructively using simple circuitry, are highly sought after. Such devices are of particular interest if they are compatible with back-end-of-line processing for CMOS integrated circuits. A variety of resistance-change technologies show promise in this respect, but a new approach that is based on switching in copper-doped silicon dioxide may be the simplest and least expensive to integrate. This paper describes the characteristics of W-(Cu/SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> )-Cu programmable metallization cell (PMC) devices formed by the thermal diffusion of Cu into deposited SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> . PMC devices operate by the electrochemical control of metallic pathways in solid electrolytes. Both unipolar and bipolar resistive switching could be attained in these devices. Bipolar switching, which is identical to that seen in PMC devices based on other solid electrolytes, was observed for low bias (a few tenths of volts) and programming currents in the microampere range. The resistance ratio between high and low states was on the order of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> , and a multibit storage is considered possible via the strong dependence of ON-state resistance on programming current. The low and high resistance states were stable for more than 5 x 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup> s. The devices could be made to exhibit unipolar switching using a negative bias on the order of -1 V combined with erase currents of hundreds of microampere to a few milliampere. In this case, the OFF/ON ratio was 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sup> .
Reverse-sequencing chewing patterns evaluation in anterior versus posterior unilateral crossbite patients (2011)

It is well established that patients with a unilateral posterior crossbite exhibit reverse-sequencing chewing patterns when chewing on the affected side. The aim of the study was to compare the prevalence of reverse-sequencing chewing cycles in patients with anterior versus posterior unilateral crossbite during chewing soft and hard boluses. Eighty-six children (39 boys, 47 girls) were included in the study: 26 (10.4 ± 2.7 years) with unilateral anterior crossbite, 43 (10.2 ± 4.2 years) with unilateral posterior crossbite, and 17 (10.6 ± 2 years) with normal occlusion were selected for the study. Mandibular movements were measured with a kinesiograph (K7, Myotronics Inc. Tukwila). The kinematic signals were analyzed using custom-made software. The results showed a low prevalence of reverse-sequencing chewing cycles in patients with anterior crossbite, without any significant difference between sides and with the control group, with both soft (P = 0.33) and hard (P = 0.29) bolus. The patients with posterior unilateral crossbite showed a significant higher prevalence of reverse-sequencing chewing cycles during chewing on the crossbite side with respect to the non-crossbite side (P < 0.001) and to the control group (P < 0.001). Comparing the patients with anterior versus posterior unilateral crossbite, a significant difference (P < 0.001) in the prevalence of reverse chewing cycles was demonstrated during chewing on the posterior crossbite side only with both soft and hard bolus. In conclusion, patients with anterior versus posterior unilateral crossbite show different functional characteristics depending on which dental region is involved.
Dielectric spectroscopy of paraelectric soft modes (1987)

Classical soft-mode behaviour above the phase-transition temperatures is discussed phenomenologically and the discussion is applied to paraelectric phases of sixteen well known and most investigated ferroelectrics of both displacive and order-disorder type. The experimental dielectric spectra ε'(v) and ε''(v) are obtained using BWO spectromctry in the 3-30 cm-1 region. In nearly all cases, the Cochran law is fulfilled in the whole region where the soft mode is underdamped and the classical critical-slowing-down law holds in regions of overdamping with the same critical temperature. As a rule, damping and oscillator strength are not critically temperature dependent. An unusual behaviour is found for Rochelle salt where below the lower transition temperature the relaxational behaviour develops into a well underdamped oscillator. A comparison with properly evaluated low-frequency dielectric data showed that in six cases, additional central-mode type dispersion near Te is expected and in some cases actually observed (TGS, SbSI, TSCC). A coupled mode analysis makes it possible to estimate the central mode parameters and the real coupling constant between the soft and central mode even if the central mode is not directly seen. In the case of BaTiO3, our new results show no soft mode stabilization and exclude any central-mode type dispersion.

Learning with Constrained and Unlabelled Data (2005)

Classification problems abundantly arise in many computer vision tasks eing of supervised, semi-supervised or unsupervised nature. Even when class labels are not available, a user still might favor certain grouping solutions over others. This bias can be expressed either by providing a clustering criterion or cost function and, in addition to that, by specifying pairwise constraints on the assignment of objects to classes. In this work, we discuss a unifying formulation for labelled and unlabelled data that can incorporate constrained data for model fitting. Our approach models the constraint information by the maximum entropy principle. This modeling strategy allows us (i) to handle constraint violations and soft constraints, and, at the same time, (ii) to speed up the optimization process. Experimental results on face classification and image segmentation indicates that the proposed algorithm is computationally efficient and generates superior groupings when compared with alternative techniques.
Effects of crosstalk in demultiplexed photonic analog-to-digital converters (2000)

Summary form only given.Development efforts are underway for a new generation of high-sampling-rate A/D converters that exploit the unique features provided by optical sampling of electrical signals. An attractive means for increasing the sampling rate of these A/D converters is to use a demultiplexer at the output of the electro-optic modulator to direct sequential optical pulses to a parallel array of M electrical A/D converters. Two types of demultiplexing schemes are being explored: time-division demultiplexing and wavelength division demultiplexing. Demultiplexing techniques require an extremely precise match of all of the M parallel A/D channels so that digital outputs from these A/D converters can be interleaved to yield a precise representation of the signal. In both time- and wavelength-demultiplexing schemes, the possibility exists that there will be incomplete isolation of the different outputs. This crosstalk will cause undesirable spurs in the spectrum obtained by digitally processing the interleaved data from the separate electronic A/D converters. This paper analyzes the level of such spurs.
