Charge recycling differential logic (CRDL) for low power application

A novel logic family, called charge recycling differential logic (CRDL), has been proposed and analyzed. CRDL reduces power consumption by utilizing a charge recycling technique with the speed comparable to those of conventional dynamic logic circuits. It has an additional benefit of improved noise margin due to inherently static operation. The noise margin problem of true single-phase-clock latch (TSPC) is also eliminated when a CRDL logic circuit is connected to it. Two swing-suppressed-input latches (SSILs), which are introduced for use with CRDL, have better performance than the conventional transmission gate latch. Moreover, a pipeline configuration with CRDL in a true two-phase clocking scheme shows completely race-free operation with no constraints on logic composition. Eight-bit Manchester carry chains and full adders were fabricated using a 0.8 /spl mu/m single-poly double-metal n-well CMOS technology to verify the relative performance of the proposed logic family. The measurement results indicate that about 16-48% improvements in power-delay product are obtained compared with differential cascode voltage switch (DCVS) logic.
Typical Size Accuracy and Control of a Process for Creating Ct- Based Virtual Bone Models

(2010) Typical accuracy and quality control of a process for creating CT­Based virtual bone models. Journal of Digital Imaging. Abstract A pragmatic method for assessing the accuracy and precision of a given processing pipeline required for converting CT image data of bones into representative 3D models is proposed. The method is based on co-processing a control object with known geometry which enables the assessment of the quality of resulting 3D models. At three stages of the conversion process distance measurements were obtained and statistically evaluated. For this study 31 CT datasets were processed. The final 3D model of the control object contained an average deviation from reference values of-1.07 ± 0.52 SD mm for edge distances and-0.647 ± 0.43 SD mm for parallel side distances of the control object. Co-processing a reference object enables the assessment of the accuracy and precision of a given processing pipeline for creating CT-based 3D bone models and is suitable for detecting most systematic or human errors when processing a CT-scan. Typical errors have an order of magnitude of the scan resolution.

Modeling and analysis of crosstalk coupling effect on the victim interconnect using the ABCD network model

After order reduction, the crosstalk model is utilized for the analysis of crosstalk coupling effects on the victim's output signal. Various timing issues related to signal waveform such as, delay time, overshoot and undershoot occurrence time etc., that in effect help to ensure the desired signal integrity (SI) and performance reliability of the SoCs, can be estimated analytically using the reduced order crosstalk model. It has been observed that the crosstalk coupling effect introduces a delay in the victim's output signal which can be significant enough, or even unacceptable, if many aggressors simultaneously couple energy to the victim line, or the line spacing between the aggressor and victim is reduced due to under-etching ,or even, the length of the victim interconnect is increased because of improper layout/routing. Influences of other interconnect parasitics on the victim's output signal can also be tested using the same model. Simulation results obtained with our reduced order model is found to be quite good and comparable to the accuracy of PSPICE simulation.
2016 Fifth International Conference on Recent Trends in Information Technology Fast In-memory Cluster Computing of Sizeable Microarray Using Spark

— Microarray technology is one of the emerging technologies in the field of genetic research, which many biologists often use to monitor expression levels of genes in a given organism. Microarray experiments are used to investigate genome-wide expression changes in health care aspects. The colossal amount of raw gene expression data often leads to computational and analytical challenges including feature selection and classification of the dataset into correct group or class. In this paper, mutual information feature selection method based on spark framework (sf-MI) is proposed to select the pertinent features. After feature selection, various classifiers i.e., Support Vector Machine (sf-SVM) and Logistic Regression (sf-LoR) based on Spark framework are applied to classify the microarray dataset. A detailed comparative analysis in terms of execution time and accuracy is enumerated on these feature selection and classifier methodologies that are based on Spark framework and conventional system respectively.
Performance characteristics of a novel tandem mass spectrometry assay for serum testosterone.

BACKGROUND Commercial immunoassays for testosterone (Te) may give inaccurate results for samples from women and children, leading to misdiagnosis and inappropriate treatment. We developed a sensitive and specific tandem mass spectrometric assay for measurement of Te at the concentrations encountered in women and children. METHODS Te was extracted with methyl tert-butyl ether from 100 microL of serum or plasma, derivatized to form an oxime, and reextracted by solid-phase extraction. Instrumental analysis was performed on an API 4000 HPLC tandem mass spectrometer in the multiple-reaction monitoring (MRM) mode. The MRM transitions (m/z) were 304-->124 and 304-->112 for Te and 307-->124 and 307-->112 for d3-Te. RESULTS Within- and between-run CVs were <12% and 7.9%, respectively. The limit of quantification was 0.0346 nmol/L (1 ng/dL). Reference intervals for sex hormone-binding globulin and total, free, and bioavailable Te were established for children of Tanner stages 1 through 5 and adult males and females. CONCLUSIONS The sensitivity and specificity of the method are adequate for analysis of Te in samples from women and children. The method requires small sample volumes, has adequate precision, and is not subject to interferences.
Learning feature characteristics

This paper describes a statistical framework for the unsupervised learning of linear filter combinations for feature characterisation. The learning strategy is two step. In the first instance, the EM algorithm is used to learn the foreground probability distribution. This is an abductive process, since we have a detailed model of the background process based on the known noise-response characteristics of the filter-bank. The second phase uses the a posteriori foreground and background probabilities to compute a weighted between-class covariance matrix. We use the principal components analysis to locate the linear filter combinations that maximise the between class covariance matrix. The new feature characterisation method is illustrated for the problem of extracting linear features from complex millimetre radar images. The method proves to be effective in learning a mixture of sine and cosine phase Gabor functions necessary to capture shadowed line structures.
Magnetic material performance of transformers in common mode active EMI filters for bearing current suppression

This paper analyses the performance of two magnetic materials used in the active filters for Common Mode (CM) electromagnetic interference (EMI) reduction in induction motor drives. In particular, active filters based on CM voltage compensation, very useful in bearing current suppression, are considered. The magnetic material is exploited for the core of the common mode transformer (CMT) that it is a crucial part of such devices because it performs the injection of the compensation voltage into the power connections between the inverter and the motor. The issues regarding the choice of the CMT core magnetic material and the windings design are discussed. The problem of the magnetic saturation, related to the desired high power/weight ratio is investigated. Furthermore, the power losses in the magnetic material under non-sinusoidal supply condition are evaluated through a suitable measurement system. A comparison of two CMTs, realized with ferrite and with nanocrystalline material cores, respectively, which are designed to perform the same filtering effect, is presented. Streszczenie.

MONEY AND WAR IN MURRAY ROTHBARD'S A HISTORY OF MONEY AND BANKING IN THE UNITED STATES

THE THESIS PROPOSED IN THIS PAPER is that strong as the protection of private property rights may seem to be in the United States, the lesson from Prof. Rothbard’s account of the history of money and banking in the U.S. has been one of the relativization of those rights, especially through interventions in the monetary and financial arrangements whenever the necessities of war financing so required.
Optimized Cache Replacement Scheme for Video on Demand Service

Video caching has gained significant attention due to its cost efficiency. In this paper, we propose an optimized cache replacement scheme based on the user request arrival pattern. The users are grouped among all possible request intervals, and the user density is calculated in each interval. The groups with highest user density are cached. Whenever a group with high user density arrives, the groups with lower density will be replaced. The simulation results show that the proposed schemes can double the hit ratio compared with the Least recently Used (LRU) scheme.

Methods for estimating infant thresholds.

Detection thresholds for 1000-Hz, 16-ms tone bursts were estimated for 3- and 6-month-old infants and for young adults. The test procedure used was the observer-based psychoacoustic procedure. Thresholds were estimated using two different adaptive procedures and the method of constant stimuli. There was little difference among the average thresholds determined by any of these techniques. The least variable thresholds were obtained in the method of constant stimuli. In addition, 10 infants at each age completed two 30-trial blocks of trials in the method of constant stimuli; 22 adults completed 8 blocks of 30 trials. For 3- and 6-month-olds and for adults, there was no significant change in average threshold between blocks. Individual 6-month-olds' thresholds rarely changed by more than 5 dB between blocks, and the correlation between the thresholds obtained in the two blocks was significant. Individual 3-month-olds' thresholds, however, sometimes changed by as much as 10 dB between blocks, and the correlation between first and second block threshold was not significant. The effects of response bias on threshold were assessed by examining receiver operating characteristic plots of hit and false alarm rates at threshold and the correlation between false alarm rate and threshold. Although there was some variability in response bias, infant/observer teams tended to respond in an unbiased fashion. In one of the adaptive procedures only, false alarm rate was significantly correlated with threshold. In all procedures, the exclusion of infants with high false alarm rates changed the average thresholds obtained by less than 5 dB. (ABSTRACT TRUNCATED AT 250 WORDS)
A New Class of TAST Codes With A Simplified Tree Structure

We consider in this paper the design of full diversity and high rate space-time codes with moderate decoding complexity for arbitrary number of transmit and receive antennas and arbitrary input alphabets. We focus our attention to codes from the threaded algebraic space-time (TAST) framework since the latter includes most known full diversity space-time codes. We propose a new construction of the component single-input single-output (SISO) encoders such that the equivalent code matrix has an upper triangular form. We accomplish this task by designing each SISO encoder to create an ISI-channel in each thread. This, in turn, greatly simplifies the QR-decomposition of the composite channel and code matrix, which is essential for optimal or near-optimal tree search algorithms, such as the sequential decoder.
Prandial Insulin and the Systemic Appearance of Meal-Derived Glucose in People With Type 1 Diabetes

The rate of appearance of meal-derived glucose is determined by a variety of factors. Ingested complex carbohydrates require enzymatic digestion into monosaccharides before absorption. Although this step per se is not rate limiting, the rate of gastric emptying and orocecal transit time may affect the rapidity with which such carbohydrates are exposed to the appropriate digestive enzymes (1). The resulting monosaccharides are then transported into the enterocyte and then into the portal vein where, ultimately, a fraction is extracted by the liver. The remainder is released into systemic circulation via the hepatic venous system. Hepatic extraction of meal-derived glucose is largely dependent on the prevailing glucose and, to a lesser extent, insulin concentrations. Intriguingly, in this issue of Diabetes Care , Pennant et al. (2) report that the rate of meal-derived glucose appearance in people with type 1 diabetes is unchanged by administration of prandial insulin 20 min before meal ingestion. This is a finding that at face value might have profound implications for affected patients treated with intensive insulin therapy. There is limited information on splanchnic extraction in type 1 diabetes. Nuclear magnetic resonance spectroscopy has demonstrated that in people with poorly controlled type 1 diabetes, glycogen synthesis is markedly impaired after ingestion of a mixed meal (3). On the other hand, a similar series of experiments under hyperinsulinemic-euglycemic conditions concluded that there was no difference in hepatic glycogen synthesis between people with well-controlled type 1 diabetes and healthy control subjects (4). The applicability of these experiments to the splanchnic extraction of enterally delivered glucose is uncertain. However, in a …
Wikipedia is a Practical Alternative to the Web for measuring Co-occurrence based Word Association

While the World Wide Web is an attractive resource, few researchers can access or manage a Web-scale corpus. Instead they use search-hit counts as a substitute for direct measurements on a web corpus. In contrast, one can download a small high quality corpus like Wikipedia and carry out exact measurements. By extensive experiments with multiple word-association measures and several public datasets, we show that for exploring document level co-occurrence based word associations, despite being three orders of magnitude smaller in size, the Wikipedia is a reasonable alternative to a web corpus that can only be accessed using search engines. Further, with Wikipedia, one can carry out measurements at a granularity finer than document scale. Instead of document level co-occurrence, one can consider a word-pair occurrence significant, only if the two words occur within a certain threshold distance of each-other. In general, such fine-grained information cannot be obtained from search engines. Our experiments show that the word level co-occurrence measures perform better than the document level measures. This indicates another practical advantage of the Wikipedia, or any other downloadable corpus, over a Web corpus which can only be accessed using search engines.
Sensivitity of the maximum parsimony algorithm to missing data

A phylogenetic algorithm computes a tree of distance relationships on a set, S, of phylogenetic descriptions (which may not be complete), given a phylogenetic-description transformation function, D, defined on S. Maximum Parsimony (MP) is a widely used phylogenetic algorithm that computes the shortest phylogenetic tree that represents the tree distances on S determined by D. To date, the sensitivity of MP to missing/incomplete data has not been systematically investigated. Although a general characterization of this sensitivity is intractable, robust empirical characterizations for typical MP configurations are possible. Here, I present an analysis of the sensitivity of several commonly used tree robustness metrics to missing/incomplete data, for a widely used MP implementation and typical MP problem set-up, applied to randomized mid-sized missing-data sets. The results show a counterintuitive limitation of one of those robustness metrics.
The structure of Argobba nominal phrase

Abstract This paper analyzes the internal structure of Argobba nominal phrase in Head-Driven Phrase Structure Grammar (HPSG) formalism. Argobba is a seriously endangered Semitic language in Ethiopia. Unlike its sister languages in the Ethio-Semitic subfamily, Argobba nouns qualified by a demonstrative, possessive pronoun and genitive NP bear a definite article. It is argued in this paper that the definite article is not an independent syntactic element, but an affix, which is attached to indefinite nouns lexically. It is argued that the derivation of Argobba definite common nouns is captured by the Definite Lexical Rule (DLR). The paper also claims that the NP internal agreement of specifiers and modifiers with the head noun is accounted for by the SPEC and MOD features that impose certain constraints on the morphosyntactic features of the head noun.
Local conflict resolution for automated taxi operations

This paper describes two techniques to achieve conflict free automated taxi processes which have been implemented by an airport traffic simulator. The first technique is based on the transitive reduction of a given routing graph, automatically creating one-way taxiway segments that allow the application of local conflict resolution strategies, preventing aircraft from getting stuck within deadlock situations. It allows an automated assignment of reasonable taxi routes to flights without the need of further manual optimizations of the search graph. The second strategy presents a dynamic method of determining temporarily shared taxiway segments during movement, which are used to generate appropriate commands to guarantee safe and efficient taxi operations. Both are then compared with planning and scheduling driven strategies and results from preliminary simulations are given to emphasize the value of the presented techniques.
Effect of static magnetic field on growth of Escherichia coli and relative response model of series piezoelectric quartz crystal.

The effect of magnetic field on the growth of bacteria was studied with the series piezoelectric quartz crystal (SPQC) sensing technique. The growth situations of Escherichia coli (E. coli) in the absence and presence of different intensities of static magnetic fields were examined and analyzed. The results showed that the growth of E. coli was inhibited due to the presence of magnetic fields. By fitting frequency shift (deltaD) versus time curves according to the frequency shift response equation of SPQC, the relationships between three kinetic growth parameters, i.e., the asymptote A, the maximum specific growth rate mu(m) and lag time lambda, and magnetic field intensity were established. Based on these results, a new response model containing the magnetic field intensity was derived as: delta(f) = 167.7 (7.25 - 7.11B)/[1 + exp[4 x 2.46e(-3.97B)/(7.25 -7.1 IB)] x (4.42 + 16.46B - t) + 2]] The kinetic parameters of bacterial growth obtained from this model are close to those obtained from the logistics popular growth model, in which the concentration of the bacteria was determined by the traditional pour plate count method.

The driven roller and the counterpressure roller cooperate with each other in such a manner that the leader spring is retained and guided therebetween.
Subchannel Allocation in Relay-Enhanced OFDMA Downlink with Imperfect Feedback

This paper studies the resource allocation for orthogonal frequency division multiple access (OFDMA) in a fixed amplify-and-forward (AF) relay link. We express closed-form average capacity results for the system when frequency allocation is based on limited and imperfect feedback information and multiple antennae are assumed at the relay node (RN) and the user equipment (UE). Feedback strategies based on the best-M method and resource block (RB)-wise one bit quantization are analyzed and compared. Capacity expressions are presented for space-time block coding (STBC) and transmit antenna selection (AS) schemes. The capacity results with imperfect feedback path are of particular interest. The results illustrate that promising tradeoff between the system performance, feedback overhead, and robustness against feedback errors can be achieved by using AS and limited feedback in frequency allocation.
Gauge fields for ultracold atoms in optical superlattices

We present a scheme that produces a strong U(1)-like gauge field on cold atoms confined in a two-dimensional square optical lattice. Our proposal relies on two essential features, a long-lived metastable excited state that exists for alkaline-earth or ytterbium atoms and an optical superlattice. As in the proposal by Jaksch and Zoller (2003 New J. Phys. 5 56), laser-assisted tunneling between adjacent sites creates an effective magnetic field. In the tight-binding approximation, atomic motion is described by the Harper Hamiltonian, with a flux across each lattice plaquette that can realistically take any value between 0 and π. We show how one can take advantage of the superlattice to ensure that each plaquette acquires the same phase, thus simulating a uniform magnetic field. We discuss the observable consequences of the artificial gauge field on non-interacting bosonic and fermionic gases. We also outline how the scheme can be generalized to non-Abelian gauge fields.
