Highly scalable on-the-fly interleaved address generation for UMTS/HSPA+ parallel turbo decoder

High throughput parallel interleaver design is a major challenge in designing parallel turbo decoders that conform to high data rate requirements of advanced standards such as HSPA+. The hardware complexity of the HSPA+ interleaver makes it difficult to scale to high degrees of parallelism. We propose a novel algorithm and architecture for on-the-fly parallel interleaved address generation in UMTS/HSPA+ standard that is highly scalable. Our proposed algorithm generates an interleaved memory address from an original input address without building the complete interleaving pattern or storing it; the generated interleaved address can be used directly for interleaved writing to memory blocks. We use an extended Euclidean algorithm for modular multiplicative inversion as a step towards reversed intra-row permutations in UMTS/HSPA+ standard. As a result, we can determine interleaved addresses from original addresses. We also propose an efficient and scalable hardware architecture for our method. Our design generates 32 interleaved addresses in one cycle and satisfies the data rate requirement of 672 Mbps in HSPA+ while the silicon area and frequency is improved compared to recent related works.
Pasture Names with Romance and Slavic Roots Facilitate Dissection of Y Chromosome Variation in an Exclusively German-Speaking Alpine Region

The small alpine district of East Tyrol (Austria) has an exceptional demographic history. It was contemporaneously inhabited by members of the Romance, the Slavic and the Germanic language groups for centuries. Since the Late Middle Ages, however, the population of the principally agrarian-oriented area is solely Germanic speaking. Historic facts about East Tyrol's colonization are rare, but spatial density-distribution analysis based on the etymology of place-names has facilitated accurate spatial mapping of the various language groups' former settlement regions. To test for present-day Y chromosome population substructure, molecular genetic data were compared to the information attained by the linguistic analysis of pasture names. The linguistic data were used for subdividing East Tyrol into two regions of former Romance (A) and Slavic (B) settlement. Samples from 270 East Tyrolean men were genotyped for 17 Y-chromosomal microsatellites (Y-STRs) and 27 single nucleotide polymorphisms (Y-SNPs). Analysis of the probands' surnames revealed no evidence for spatial genetic structuring. Also, spatial autocorrelation analysis did not indicate significant correlation between genetic (Y-STR haplotypes) and geographic distance. Haplogroup R-M17 chromosomes, however, were absent in region A, but constituted one of the most frequent haplogroups in region B. The R-M343 (R1b) clade showed a marked and complementary frequency distribution pattern in these two regions. To further test East Tyrol's modern Y-chromosomal landscape for geographic patterning attributable to the early history of settlement in this alpine area, principal coordinates analysis was performed. The Y-STR haplotypes from region A clearly clustered with those of Romance reference populations and the samples from region B matched best with Germanic speaking reference populations. The combined use of onomastic and molecular genetic data revealed and mapped the marked structuring of the distribution of Y chromosomes in an alpine region that has been culturally homogeneous for centuries.
Tolerance-Based Adaptive Online Outlier Detection for Internet of Things

The cheap and low-quality sensor devices are usually used for event detection in Internet of Things (IoT), and they put limitations on power, memories and computing capabilities. Those limitations need to be considered while designing our outlier detection algorithm. In this paper, we try to present an adaptive online outlier detection algorithm to handle data measurements for event detection. Namely, the proposed algorithm needs to provide the capability to tolerant those data which would be classified as outliers by traditional algorithms. With an accurate ratio of outliers and a tolerance parameter, a tolerance-based adaptive online outlier detection (TAOOD) algorithm is proposed. The contributions of TAOOD are two folds: (i) TAOOD decreases the amount of transmitted data by discarding duplicate data and outliers, (ii) TAOOD eliminates the limitation of original window-based outlier detection algorithm by adapting an accurate ratio of outliers and a tolerance parameter. Extensive simulations demonstrate effectiveness of the proposed algorithm.
Facilitating Conflict Resolution of Models for Automated Enterprise Architecture Documentation

Enterprise Architecture (EA) management relies on solid and up-to-date information about the current state of an EA. In current practices the manual collection of information is prevailing resulting in an error-prone, time-consuming, and expensive task. Recent research efforts seek to automate this task by integrating existing information sources in the organization to optimize the EA documentation process. While automation of EA documentation enables many advantages, the transformation of the collected information to an EA model remains an unresolved challenge since it cannot be automated completely. In particular, conflicts resulting from partial transformations require involvement of EA Stakeholders possibly not having a technical background. In this paper we propose an approach for the conflict resolution facilitating our long-term goal of automated EA documentation. We illustrate our approach using a productive Enterprise Service Bus from a leading organization of the fashion industry and evaluate our approach with expert interviews.
Reference and automatic marking of glottal opening instants using EGG signal

Glottal Opening Instants (GOIs) are those instants at which the glottis opens from the closed phase of glottal activity. Detecting GOIs leads to parameterization of glottal activity regions in terms of open quotient that may be helpful for speaker verification and speech enhancement tasks. Accurately marking such instants directly from speech signal is still a challenging task. Alternatively, Electroglottograph (EGG) signal provides an accurate means of picking such instants from the voiced activity regions of the speech production. In this paper a detailed procedure of reference marking GOIs manually from EGG signal is reported and then a method is proposed to pick those instants automatically. Eight different subjects are used to create reference markings for selected sentences from CMU-Arctic database of 3 different speakers. The mean average positions obtained from the markings of different subjects within a glottal cycle are used as reference markings to evaluate the automatic procedure.
Alternative Investments: Inflation Hedger or Mean-Variance Efficient?

Using NCRIEF farmland and timberland smoothed indices over the period from 1992Q1 to 2012Q3 and a new de-smoothing approach offered by Fisher et al. (1994), we explore the mean-variance diversification features of farmland and timberland assets. Our empirical results show that diversification characteristics of both asset classes significantly improve the portfolio choice of the investors. Our de-smoothed series demonstrate that at a given level of risk both farmland and timberland have the potential to increase the returns of a diversified traditional asset portfolio during the period of market turmoil and high uncertainty. The results remain consistent even in a mirror image situation prevailing in the financial markets. Furthermore, both asset classes are found possessing weak inflation hedging characteristics during inflationary periods.
The IrPen: A 6-DOF Pen for Interaction with Tablet Computers

Researchers have proposed various techniques for over-the-surface interaction using pens. However, current pen systems can't properly support these techniques because of their limited tracking abilities. The IrPen, an extension of the IrCube tracker, is a six-degree-of-freedom pen system that properly supports over-the-surface interaction on tablet computers. Besides incorporating the tracker's basic operating principles, the IrPen takes into account tablet-specific requirements. It employs a sensor small enough for tablets, and the pen structure minimizes issues caused by reflections from a tablet surface. The design also addresses issues related to occlusion and ambient lighting.
High Quality Genomic Copy Number Data from Archival Formalin-Fixed Paraffin-Embedded Leiomyosarcoma: Optimisation of Universal Linkage System Labelling

Most soft tissue sarcomas are characterized by genetic instability and frequent genomic copy number aberrations that are not subtype-specific. Oligonucleotide microarray-based Comparative Genomic Hybridisation (array CGH) is an important technique used to map genome-wide copy number aberrations, but the traditional requirement for high-quality DNA typically obtained from fresh tissue has limited its use in sarcomas. Although large archives of Formalin-fixed Paraffin-embedded (FFPE) tumour samples are available for research, the degradative effects of formalin on DNA from these tissues has made labelling and analysis by array CGH technically challenging. The Universal Linkage System (ULS) may be used for a one-step chemical labelling of such degraded DNA. We have optimised the ULS labelling protocol to perform aCGH on archived FFPE leiomyosarcoma tissues using the 180k Agilent platform. Preservation age of samples ranged from a few months to seventeen years and the DNA showed a wide range of degradation (when visualised on agarose gels). Consistently high DNA labelling efficiency and low microarray probe-to-probe variation (as measured by the derivative log ratio spread) was seen. Comparison of paired fresh and FFPE samples from identical tumours showed good correlation of CNAs detected. Furthermore, the ability to macro-dissect FFPE samples permitted the detection of CNAs that were masked in fresh tissue. Aberrations were visually confirmed using Fluorescence in situ Hybridisation. These results suggest that archival FFPE tissue, with its relative abundance and attendant clinical data may be used for effective mapping for genomic copy number aberrations in such rare tumours as leiomyosarcoma and potentially unravel clues to tumour origins, progression and ultimately, targeted treatment.
GraphJet: Real-Time Content Recommendations at Twitter

This paper presents GraphJet, a new graph-based system for generating content recommendations at Twitter. As motivation, we trace the evolution of our formulation and approach to the graph recommendation problem, embodied in successive generations of systems. Two trends can be identified: supplementing batch with real-time processing and a broadening of the scope of recommendations from users to content. Both of these trends come together in Graph-Jet, an in-memory graph processing engine that maintains a real-time bipartite interaction graph between users and tweets. The storage engine implements a simple API, but one that is sufficiently expressive to support a range of recommendation algorithms based on random walks that we have refined over the years. Similar to Cassovary, a previous graph recommendation engine developed at Twitter, GraphJet assumes that the entire graph can be held in memory on a single server. The system organizes the interaction graph into temporally-partitioned index segments that hold adjacency lists. GraphJet is able to support rapid ingestion of edges while concurrently serving lookup queries through a combination of compact edge encoding and a dynamic memory allocation scheme that exploits power-law characteristics of the graph. Each GraphJet server ingests up to one million graph edges per second, and in steady state, computes up to 500 recommendations per second, which translates into several million edge read operations per second.
A fuzzy reasoning scheme for context sharing decision making

In context aware mobile applications users' sensitive information will be available to be collected by a large number of service providers, which might threaten users privacy. In this paper, we propose the use of fuzzy logic in helping automating consent decisions done by end users. The proposed fuzzy approach has been implemented based on Mamdani fuzzy inference systems, and has been integrated in one of the services provided by a real time UMTS mobile platform known as MIES at the university campus with real users. Results obtained give the indication of possibilities of adopting this approach in practical applications.
Typeset Using Revt E X 1

Enhancement of the electronic contribution to the low temperature specific heat of Fe/Cr magnetic multilayer Abstract We measured the low temperature specific heat of a sputtered (F e 23Å /Cr 12Å) 33 magnetic multilayer, as well as separate 1000Å thick Fe and Cr films. Magnetoresistance and magnetization measurements on the multilayer demonstrated antiparallel coupling between the Fe layers. Using microcalorimeters made in our group, we measured the specific heat for 4 < T < 30 K and in magnetic fields up to 8 T for the multilayer. The low temperature electronic specific heat coefficient of the multilayer in the temperature range 4 < T < 14 K is γ M L = 8.4 mJ/K 2 g − at. This is significantly larger than that measured for the Fe or Cr films (5.4 and. 3.5 mJ/K 2 mol respectively). No magnetic field dependence of γ M L was observed up to 8 T. These results can be explained by a softening of the phonon modes observed in the same data and the presence of an Fe-Cr alloy phase at the interfaces.
Investigating the impact of destination image on Total Tourists' Experience (TTE) and destination loyalty: Using structural equation modelling approach

The importance of value creation via customer experiences has been widely established. Providing quality products and services is no longer adequate for business sustainability since customers also need to acquire relevant satisfactory experiences. This paper aims to address the gap by empirically investigating impact of destination image on Total Tourists' Experience (TTE) and destination loyalty. A hypothesized model which integrates three abstraction levels of destination image (country image, island image and resort image), TTE and destination loyalty was developed, analyzed and tested rigorously using structural equation modelling procedure with 173 usable data-sets of international tourists. The data was collected using self-administered structured questionnaire approach within the vicinity of an international tourist island. Final results reveal that island image and country image are significant predictors of TTE, and surprisingly, it was unveiled that resort image does not have any significant influence on TTE. In addition, TTE has a positive effect on destination loyalty. These findings have important implications for future research directions and destination marketers.
Abnormal Categorization and Perceptual Learning in Patients with Hippocampal Damage

Prevailing theory holds that the medial temporal lobe (MTL) subserves declarative memory exclusively, whereas nondeclarative memory is independent of this brain region. Recent studies in patients with amnesia, however, have shown that performance on declarative memory tasks may not always be dependent on a single MTL memory system, instead highlighting the critical role of anatomically distinct structures in processing different stimulus types. In particular, the hippocampus has been implicated in spatial memory, whereas perirhinal cortex seems critical for object memory. To assess whether stimulus type would also be a key dimension in nondeclarative memory, patients with selective hippocampal lesions were tested on simple categorization and perceptual learning of faces and virtual reality scenes. The patients demonstrated preserved categorization and perceptual learning of faces but abnormal performance when the stimuli to be discriminated were virtual reality scenes. These findings imply that stimulus type may be a more critical predictor of performance on memory tasks (declarative and nondeclarative) than previously thought. They also suggest that reports of good nondeclarative memory after MTL damage may, in some cases, simply reflect the use of stimuli that fail to tap the processes dependent on structures in this region, such as spatial processing in the case of the hippocampus.
A cell culture model of the blood-brain barrier

Endothelial cells that make up brain capillaries and constitute the blood-brain barrier become different from peripheral endothelial cells in response to inductive factors found in the nervous system. We have established a cell culture model of the blood-brain barrier by treating brain endothelial cells with a combination of astrocyte-conditioned medium and agents that elevate intracellular cAMP. These cells form high resistance tight junctions and exhibit low rates of paracellular leakage and fluid-phase endocytosis. They also undergo a dramatic structural reorganization as they form tight junctions. Results from these studies suggest modes of manipulating the permeability of the blood-brain barrier, potentially providing the basis for increasing the penetration of drugs into the central nervous system.
Parental Altruism and Inter Vivos Transfers: Theory and Evidence

This paper uses PSID data on the extended family to test whether inter vivos transfers from parents to children are motivated by altruism. Specifically, the paper tests whether an increase by one dollar in the income of parents actively making transfers to a child coupled with a one dollar reduction in that child's income results in the parents' increasing their transfer to the child by one dollar. This restriction on parental and child transfer‐income derivatives is derived for the standard altruism model augmented to include uncertainty and liquidity constraints. These additional elements pin down the timing of inter vivos transfers. The method used to estimate income‐transfer derivatives takes into account unobserved heterogeneity across families in the degree of altruism. The findings strongly reject the altruism hypothesis. Redistributing one dollar from a recipient child to donor parents leads to less than a 13‐cent increase in the parents' transfer to the child, far less than the one‐dollar increase implied by altruism.
Indirect Genetic Effects Influence Antipredator Behavior in Guppies: Estimates of the Coefficient of Interaction Psi and the Inheritance of Reciprocity

How and why cooperation evolves, particularly among nonrelatives, remains a major paradox for evolutionary biologists and behavioral ecologists. Although much attention has focused on fitness consequences associated with cooperating, relatively little is known about the second component of evolutionary change, the inheritance of cooperation or reciprocity. The genetics of behaviors that can only be expressed in the context of interactions are particularly difficult to describe because the relevant genes reside in multiple social partners. Indirect genetic effects (IGEs) describe the influence of genes carried in social partners on the phenotype of a focal individual and thus provide a novel approach to quantifying the genetics underlying interactions such as reciprocal cooperation. We used inbred lines of guppies and a novel application of IGE theory to describe the dual genetic control of predator inspection and social behavior, both classic models of reciprocity. We identified effects of focal strain, social group strain, and interactions between focal and group strains on variation in focal behavior. We measured &psgr;, the coefficient of the interaction, which describes the degree to which an individuals phenotype is influenced by the phenotype of its social partners. The genetic identity of social partners substantially influences inspection behavior, measures of threat assessment, and schooling and does so in positively reinforcing manner. We therefore demonstrate strong IGEs for antipredator behavior that represent the genetic variation necessary for the evolution of reciprocity.
Surgical treatment of a ventricular aneurysm in a patient with essential thrombocythemia complicated by acute myocardial infarction: A case report

Essential thrombocythemia (ET) is a chronic clonal myeloproliferative disorder, which is often complicated by arterial or venous thrombosis and idiopathic bleeding diathesis. The present study reports a female patient with ET complicated by acute myocardial infarction, leading to ventricular aneurysm following interventional therapy for 3 years and a subsequent in-stent restenosis. Following careful examination, a ventricular aneurysm resection and coronary artery bypass graft were carried out. During this case, the monitoring and controlling of the platelet count, pre- and post-operatively, was extremely important for successful surgery.
Functional reconstitution of bacterial Tat translocation in vitro

The Tat (twin‐arginine translocation) pathway is a Sec‐independent mechanism for translocating folded preproteins across or into the inner membrane of Escherichia coli. To study Tat translocation, we sought an in vitro translocation assay using purified inner membrane vesicles and in vitro synthesized substrate protein. While membrane vesicles derived from wild‐type cells translocate the Sec‐dependent substrate proOmpA, translocation of a Tat‐dependent substrate, SufI, was not detected. We established that in vivo overexpression of SufI can saturate the Tat translocase, and that simultaneous overexpression of TatA, B and C relieves this SufI saturation. Using membrane vesicles derived from cells overexpressing TatABC, in vitro translocation of SufI was detected. Like translocation in vivo, translocation of SufI in vitro requires TatABC, an intact membrane potential and the twin‐arginine targeting motif within the signal peptide of SufI. In contrast to Sec translocase, we find that Tat translocase does not require ATP. The development of an in vitro translocation assay is a prerequisite for further biochemical investigations of the mechanism of translocation, substrate recognition and translocase structure.
