An Audit Environment for Outsourcing of Frequent Itemset Mining

Finding frequent itemsets is the most costly task in association rule mining. Outsourcing this task to a service provider brings several benefits to the data owner such as cost relief and a less commitment to storage and computational resources. Mining results, however, can be corrupted if the service provider (i) is honest but makes mistakes in the mining process, or (ii) is lazy and reduces costly computation, returning incomplete results, or (iii) is malicious and contaminates the mining results. We address the integrity issue in the outsourcing process, i.e., how the data owner verifies the correctness of the mining results. For this purpose, we propose and develop an audit environment, which consists of a database transformation method and a result verification method. The main component of our audit environment is an artificial itemset planting (AIP) technique. We provide a theoretical foundation on our technique by proving its appropriateness and showing probabilistic guarantees about the correctness of the verification process. Through analytical and experimental studies, we show that our technique is both effective and efficient.
Mental illness, substance abuse, demographics and offending: dual diagnosis in the suburbs

High rates of offending and violence have been found in patients with co-morbid severe mental illness and substance misuse (dual diagnosis), although research has focused upon inner-city populations. This study compares offending and violence rates in patients with dual diagnosis (DD) and patients with psychosis only, drawing on a more demographically representative population. Forty patients with severe mental disorders were interviewed in a geographically defined catchment area in Croydon, Surrey. Cases of alcohol or drug misuse were identified, and measures of lifetime history of offending (including violence) and recent violence were obtained. DD patients were more likely to report a lifetime history of both offending and violence than patients with psychosis only (although gender may play a greater role than substance misuse). Few instances of recent violence were found, and no between-group differences were detected. The medical caserecords of DD patients were significantly more likely to contain a lifetime history of non-substance misuse-related offending, but not violence. However, the extent to which substance misuse contributes to violence and offending independently of contextual variables requires further investigation.
Discourse analysis and corporate social responsibility: a qualitative approach

Purpose – The purpose of this paper is to examine how firms build and develop corporate discourse in the field of corporate social responsibility (CRS). The paper has two main objectives: to clarify notions that are used when analyzing discourse; and to provide a qualitative methodology to analyze how the discourse is used to construct a CRS strategy.Design/methodology/approach – The paper presents a qualitative methodology, deconstructing four CRS reports using a story‐telling approach.Findings – The analysis shows that firms construct their environment while marketing the report on social responsibility, in order to make of it an asset in an institutional communication system.Research limitations/implications – Further attention should be devoted to the specificity of qualitative approach and to discourse analysis (selection of the corpus, validity and triangulation, etc.). Originality/value – The paper shows how discourse can be used to provide competitive advantage. It also provides a clear framework w.

Extending the VA CPRS electronic patient record order entry system using natural language processing techniques

An automated practitioner order entry system was recently implemented at the VA Puget Sound Health Care System. Since the introduction of this system, we have experienced various problems, among them an increase in time required for practitioners to enter orders. In order to improve usability and acceptance of the order entry, an alternate pathway was built within CPRS that allows direct natural language based order entry. Implementation of the extension in CPRS has been made possible because of the three layers CPRS architecture and its strong object oriented models. This paper discusses the advantages and needs for a natural language based order entry system and its implementation within an existing order entry system.
Mapping Tasks to Interactions for Graph Exploration and Graph Editing on Interactive Surfaces

Graph exploration and editing are still mostly considered independently and systems to work with are not designed for todays interactive surfaces like smartphones, tablets or tabletops. When developing a system for those modern devices that supports both graph exploration and graph editing, it is necessary to 1) identify what basic tasks need to be supported, 2) what interactions can be used, and 3) how to map these tasks and interactions. This technical report provides a list of basic interaction tasks for graph exploration and editing as a result of an extensive system review. Moreover, different interaction modalities of interactive surfaces are reviewed according to their interaction vocabulary and further degrees of freedom that can be used to make interactions distinguishable are discussed. Beyond the scope of graph exploration and editing, we provide an approach for finding and evaluating a mapping from tasks to interactions, that is generally applicable. Thus, this work acts as a guideline for developing a system for graph exploration and editing that is specifically designed for interactive surfaces.

A Compact MIMO Array of Planar End-Fire Antennas for WLAN Applications

An approach to the design of multiple-input multiple-output (MIMO) arrays exploiting planar directive antennas is presented. It is well known that pattern orthogonality is a key aspect to reach low correlation, and thus to improve channel capacity in rich multipath environments. However, attention is often focused on reducing mutual coupling rather than optimizing the active element patterns. In this communication a planar MIMO array of printed Yagi-Uda antennas with integrated balun is presented. The end-fire radiation mechanism of the Yagi-Uda is exploited to obtain a triangular array of three sectoral antennas. This allows to achieve nearly orthogonal patterns, while keeping a low mutual coupling among radiating elements. A properly shaped ground at the feeding points allows to increase the isolation between the antennas, even in such a compact layout. A laboratory model has been characterized experimentally, and the effectiveness of the proposed design in terms of theoretical achievable capacity is demonstrated through numerical simulations considering IEEE 802.11n multipath fading channel models.
A new approach to the development of the cerebellum provided by the quail-chick marker system.

We have used the quail-chick chimera system to reveal the cell migrations and settling pattern involved in the construction of the cerebellum. Three types of orthotopic transplantations were carried out, between quail and chick embryos, at the 12-somite stage: exchanges of (i) the whole metencephalic vesicle, (ii) the lateral half of this vesicle and (iii) the diencephalic plus the mesencephalic vesicles. Histological study of chimeric embryos and young chicks provided the following results: longitudinal morphogenetic movements distort the embryonic neural tube as early as the fifth embryonic day, so that the dorsal limit of the mes-, met- and myelencephalic vesicles are displaced caudad and their ventral limits rostrad. This leads to a participation of mesencephalic vesicular material in the construction of the cerebellum. Cells originating in the mesencephalic vesicle are found in a rostromedial V-shaped region, in all the cerebellar cellular layers, except the external granular layer, the presumptive territory of which is entirely located in the metencephalic vesicle. The chimerism of the rostromedial part of the cerebellum allows the analysis of the origin of the various cerebellar cell types. We find (i) that the Purkinje cells always have the same cellular marker as the ventricular epithelium radially beneath them. This strongly suggests that these cells reach their final localization following strictly radial migrations. (ii) Most of the small cells surrounding the Purkinje neurons and most of the neurons and glial cells of the molecular layer are also of the same type as the ventricular epithelium they surmount, i.e. different from the type of the external granular layer cells. Therefore, they are not derived from the external granular layer and are not of the same origin as the granule cells as previously believed. Unilateral substitutions of the metencephalic vesicle revealed that transverse cell migrations occur across the sagittal plane. They have been observed mainly in the inner and external granular layers, but also, though to a lesser extent, in the molecular layer and in the cell layer located at the level of the Purkinje neurons. These observations show that the position of cerebellar cells is determined by both morphogenetic movements and cell type-specific active radial and tangential migrations. The quail-chick chimera system is thus able to provide new information both on the origin of cerebellar cells and how each cell type assumes its final position.
Sentence-level quality estimation by predicting HTER as a multi-component metric

This submission investigates alternative machine learning models for predicting the HTER score on the sentence level. Instead of directly predicting the HTER score, we suggest a model that jointly predicts the amount of the 4 distinct post-editing operations, which are then used to calculate the HTER score. This also gives the possibility to correct invalid (e.g. negative) predicted values prior to the calculation of the HTER score. Without any feature exploration, a multi-layer perceptron with 4 outputs yields small but significant improvements over the baseline.
Mapping of a new locus for congenital anomalies of the kidney and urinary tract on chromosome 8q24.

BACKGROUND Congenital anomalies of the kidney and urinary tract (CAKUT) account for the majority of end-stage renal disease in children (50%). Previous studies have mapped autosomal dominant loci for CAKUT. We here report a genome-wide search for linkage in a large pedigree of Somalian descent containing eight affected individuals with a non-syndromic form of CAKUT. METHODS Clinical data and blood samples were obtained from a Somalian family with eight individuals with CAKUT including high-grade vesicoureteral reflux and unilateral renal agenesis. Total genome search for linkage was performed using a 50K SNP Affymetric DNA microarray. As neither parent is affected, the results of the SNP array were analysed under recessive models of inheritance, with and without the assumption of consanguinity. RESULTS Using the non-consanguineous recessive model, a new gene locus (CAKUT1) for CAKUT was mapped to chromosome 8q24 with a significant maximum parametric Logarithm of the ODDs (LOD) score (LOD(max)) of 4.2. Recombinations were observed in two patients defining a critical genetic interval of 2.5 Mb physical distance flanked by markers SNP_A-1740062 and SNP_A-1653225. CONCLUSION We have thus identified a new non-syndromic recessive gene locus for CAKUT (CAKUT1) on chromosome 8q24. The identification of the disease-causing gene will provide further insights into the pathogenesis of urinary tract malformations and mechanisms of renal development.
Transmission Dynamics of Methicillin-Resistant Staphylococcus aureus in Pigs

From the mid-2000s on, numerous studies have shown that methicillin-resistant Staphylococcus aureus (MRSA), renowned as human pathogen, has a reservoir in pigs and other livestock. In Europe and North America, clonal complex (CC) 398 appears to be the predominant lineage involved. Especially worrisome is its capacity to contaminate humans in close contact with affected animals. Indeed, the typical multi-resistant phenotype of MRSA CC398 and its observed ability of easily acquiring genetic material suggests that MRSA CC398 strains with an increased virulence potential may emerge, for which few therapeutic options would remain. This questions the need to implement interventions to control the presence and spread of MRSA CC398 among pigs. MRSA CC398 shows a high but not fully understood transmission potential in the pig population and is able to persist within that population. Although direct contact is probably the main route for MRSA transmission between pigs, also environmental contamination, the presence of other livestock, the herd size, and farm management are factors that may be involved in the dissemination of MRSA CC398. The current review aims at summarizing the research that has so far been done on the transmission dynamics and risk factors for introduction and persistence of MRSA CC398 in farms.
Interaction between Homozygous β0 Thalassaemia and the Swiss Type of Hereditary Persistence of Fetal Haemoglobin

The interaction between β0 thalassaemia and an heterocellular form of hereditary persistence of fetal haemoglobin (HPFH), presumably of the Swiss type, has been studied in three generations of a family in which both traits occur. The haematological parameters and the segregation of the two characters in the family suggest that the propositus, a 52‐year‐old male from southern Sardinia, is homozygous for β0 thalassaemia and carrier of the HPFH.
Game Theoretic Model Predictive Control for Distributed Energy Demand-Side Management

Distributed energy generation and storage are widely investigated demand-side management (DSM) technologies that are scalable and integrable with contemporary smart grid systems. However, prior research has mainly focused on day-ahead optimization for these distributed energy resources while neglecting forecasting errors and their often detrimental consequences. We propose a novel game theoretic model predictive control (MPC) approach for DSM that can adapt to real-time data. The MPC-based algorithm produces subgame perfect equilibrium strategies for distributed generation and storage with perfect forecasting information, and is shown to be more effective than a day-ahead scheme when mean forecasting errors greater than 10% are present. This robust and continuous MPC approach reduces effective forecasting errors, and in doing so, achieves greater electricity cost savings and peak to average demand ratio reduction than the day-ahead optimization scheme.
DNA Computation Based Approach for Enhanced Computing Power

DNA computing is a discipline that aims at harnessing individual molecules at the nano-scopic level for computational purposes. Computation with DNA molecules possesses an inherent interest for researchers in computers and biology. Given its vast parallelism and high-density storage, DNA computing approaches are employed to solve many problems. DNA has also been explored as an excellent material and a fundamental building block for building large-scale nanostructures, constructing individual nano- mechanical devices, and performing computations. Molecular-scale autonomous programmable computers are demonstrated allowing both input and output information to be in molecular form. This paper presents a review of recent advancements in DNA computing and presents major achievements and challenges for researchers in the coming future.
Epilepsies as Dynamical Diseases of Brain Systems: Basic Models of the Transition Between Normal and Epileptic Activity

Summary: Purpose: The occurrence of abnormal dynamics in a physiological system can become manifest as a sudden qualitative change in the behavior of characteristic physiologic variables. We assume that this is what happens in the brain with regard to epilepsy. We consider that neuronal networks involved in epilepsy possess multistable dynamics (i.e., they may display several dynamic states). To illustrate this concept, we may assume, for simplicity, that at least two states are possible: an interictal one characterized by a normal, apparently random, steady ‐state of ongoing activity, and another one that is characterized by the paroxysmal occurrence of a synchronous oscillations (seizure).
Engineering of α‐conotoxin MII‐derived peptides with increased selectivity for native α6β2∗ nicotinic acetylcholine receptors

α6β2∗ Nicotinic acetylcholine receptors are expressed in selected central nervous system areas, where they are involved in striatal dopamine (DA) release and its behavioral consequences, and other still uncharacterized brain activities. α6β2∗ receptors are selectively blocked by the α‐conotoxins MII and PIA, which bear a characteristic N‐ terminal amino acid tail [arginine (R), aspartic acid (D), and proline (P)]. We synthesized a group of PIA‐related peptides in which R1 was mutated or the RDP motif gradually removed. Binding and striatal DA release assays of native rat α6β2∗ receptors showed that the RDP sequence, and particularly residue R1, is essential for the activity of PIA. On the basis of molecular modeling analyses, we synthesized a hybrid peptide (RDP‐MII) that had increased potency (7‐fold) and affinity (13‐fold) for α6β2∗ receptors but not for the very similar α3β2∗ subtype. As docking studies also suggested that E11 of MII might be a key residue engendering α6β2∗ vs. α3β2∗ selectivity, we prepared MII[E11R] and RDP‐MII[E11R] peptides. Their affinity and potency for native α6β2∗ receptors were similar to those of their parent analogues, whereas, for the oocyte expressed rat α3β2∗ subtype, they showed a 31‐ and 14‐fold lower affinity and 21‐ and 3.5‐fold lower potency. Thus, MII[E11R] and RDP‐MII[E11R] are potent antagonists showing a degree of α6β2∗ vs. α3β2∗ selectivity in vivo. —Pucci, L. , Grazioso, G. , Dallanoce, C. , Rizzi, L. , De Micheli, C. , Clementi, F. , Bertrand, S. , Bertrand, D. , Longhi, R. , De Amici, M. , Gotti, C.

Chocolate milk and endurance exercise recovery: protein balance, glycogen, and performance.

PURPOSE This study examined effects of fat-free chocolate milk (MILK) consumption on kinetic and cellular markers of protein turnover, muscle glycogen, and performance during recovery from endurance exercise. METHODS Male runners participated in two trials separated by 1 wk and consumed either MILK or a nonnitrogenous isocaloric carbohydrate (CHO) control beverage (CON) after a 45-min run at 65% of V˙O(2peak). Postexercise muscle protein fractional synthetic rate (FSR) and whole-body protein turnover were determined during 3 h of recovery using muscle biopsies and primed constant infusions of L-[ring-²H₅]phenylalanine and L-[1-¹³C]leucine, respectively. Phosphorylation of translational signaling proteins and activity of proteolytic molecules were determined using Western blotting and enzymatic activity assays. Muscle glycogen was quantified, and treadmill time to exhaustion was determined after the recovery period. RESULTS Consuming MILK after exercise resulted in higher mixed muscle FSR with lower whole-body proteolysis and synthesis compared with CON (P ≤ 0.05). Phosphorylation of eIF4E-BP1 and FOXO3a was higher for MILK (P < 0.01), whereas Akt phosphorylation was lower during recovery regardless of dietary treatment (P < 0.05). Enzymatic activity assays indicated lower caspase-3 activity during recovery for MILK (P < 0.01) and higher 26S proteasome activity for CON (P < 0.01). Muscle glycogen was not affected by either dietary treatment; however, time to exhaustion was greater for MILK than for CON (P < 0.05). CONCLUSIONS The effects of consumption of MILK after endurance exercise on FSR, signaling molecules of skeletal muscle protein turnover, leucine kinetics, and performance measures suggest unique benefits of milk compared with a CHO-only beverage.
