Title Grand challenge : Automatic anomaly detection over sliding windows

With the advances in the Internet of Things and rapid generation of vast amounts of data, there is an ever growing need for leveraging and evaluating event-based systems as a basis for building realtime data analytics applications. The ability to detect, analyze, and respond to abnormal patterns of events in a timelymanner is as challenging as it is important. For instance, distributed processing environment might affect the required order of events, time-consuming computations might fail to scale, or delays of alarms might lead to unpredicted system behavior. The ACM DEBS Grand Challenge 2017 focuses on real-time anomaly detection for manufacturing equipments based on the observation of a stream of measurements generated by embedded digital and analogue sensors. In this paper, we present our solution to the challenge leveraging the Apache Flink stream processing framework and anomaly ordering based on sliding windows, and evaluate the performance in terms of event latency and throughput.
Time-dependent improvement in functional outcome following LCS rotating platform knee replacement

Background and purpose Long-term follow-up studies after total knee replacement (TKR) using an LCS rotating platform have shown survival rates of up to 97%. Few studies have evaluated short-term functional outcome and its improvement over time. We determined the time course of functional outcome as evaluated by the knee injury and osteoarthritis outcome score (KOOS) over the first 4 years after TKR using the LCS mobile bearing. Patients and methods 50 unselected patients (mean age 70 (40–85) years, 33 women) with osteoarthritis in one knee underwent TKR with an LCS mobile bearing. Data were collected by an independent investigator preoperatively and at 6 weeks, 3 months, 6 months, 1 year, 2 years and 4 years postoperatively. KOOS, a self-assessment function score validated for this purpose, and range of motion (ROM) were determined at all follow-ups. Results The mean KOOS pain score increased from 43 before surgery to 66 at 6 weeks and 88 at 2 years. It was 84 at 4 years. The mean KOOS activities of daily living score (ADL) increased from 49 before surgery to 73 at 6 weeks, then gradually to 90 at 2 years. It decreased to 79 at 4 years. Mean passive ROM was 112° before surgery, 78° at departure from hospital, and then gradually increased to 116° at 2 years and 113° at 4 years. Interpretation Recovery after TKR is time-dependent. Most of the expected improvement in pain and function is achieved at 6 months postoperatively, but some further improvement can be expected up to 2 years postoperatively. ROM will also gradually improve up to 2 years after TKR, and reach the same level as before surgery.
Communal larval rearing of European lobster (Homarus gammarus): family identification by microsatellite DNA profiling an offspring fitness.

Stock enhancement experiments of European lobster ( Homarus gammarus ) have been carried out around the Kvitsøy Islands in south-western Norway since 1990. In addition to releases of coded wire tagged lobster juveniles (cultured) and subsequent monitoring of commercial fishery, a lobster hatchery was established in 1997. Several experiments were made on the communal-rearing approach where the performance of mixed larval groups (families) was evaluated under identical conditions. Berried females of wild and cultured origin and their respective fertilised eggs were screened by using microsatellite DNA profiling involving a multiplex set of six lobster specific primers, thereby allowing determination of both parental genotypes. Each female were kept separately during hatching, and the offspring were later mixed and raised in a communal rearing system. The early-larval survival was estimated at stage IV (bottom stage), and the survivors were identified to family and group by microsatellite profiling. Five different communal experiments were conducted, representing offspring from 65 berried females. Of the surviving larvae, 6.3% could not be assigned to family due to degraded DNA and no PCR amplification. Significant differences in early survival between offspring of wild and cultured origin were found in the experiments. No differences between the groups were found in stage IV larval size. Based on the pooled data on survival (as a measure of early larvae fitness) offspring of cultured females displayed a relative fitness of 60% in comparison to offspring from wild females. Large variation in survival was also observed among families within the b wild Q and b cultured Q groups, suggesting a genetic component for these traits and a potential for selective breeding.
Exploring a parameterised portrait painting space

We overview our interdisciplinary work building parameterised knowledge domains and their authoring tools that allow for expression systems, which move through a space of painterly portraiture. With new computational systems it is possible to conceptually dance, compose and paint in higher-level conceptual spaces. We are interested in building art systems that support exploring these spaces and in particular report on our software-based artistic toolkit and resulting experiments using parameter spaces in face-based new media portraiture. This system allows us to parameterise the open cognitive and vision-based methodology that human artists have intuitively evolved over centuries into a domain toolkit to explore aesthetic realisations and interdisciplinary questions about the act of portrait painting as well as the general creative process. These experiments and questions can be explored by traditional and new media artists, art historians, cognitive scientists and other scholars.
A connectionist account of Spanish determiner production Journal Item

Evidence from experimental studies of Spanish children’s production of determiners reveals that they pay more attention to phonological cues present in nouns than to natural semantics when assigning gender to determiners (Pérez-Pereira, 1991). This experimental work also demonstrated that Spanish children are more likely to produce the correct determiner when given a noun with phonological cues which suggest it is masculine, and more likely to assign masculine gender to nouns with ambiguous cues. In this paper, we investigate the phonological cues available to children and seek to explore the possibility that differential frequency in the linguistic input explains the priority given to masculine forms when children are faced with ambiguous novel items. A connectionist model of determiner production was incrementally trained on a lexicon of determiner–noun phrases taken from parental speech in [*] Andrew Nix was funded by a University of Hertfordshire Research Studentship.

Comparative Analysis on Nutritional and Antinutritional factors in Raw and Blanched Crotalaria laburnoides Klotzsch leaves from Iramba District , Tanzania

This research aimed at investigating the nutritional and antinutritional contents of the leaves of wild edible plant, Crotalaria laburnoides (commonly known as „Nsonga‟ by natives), in order to provide knowledge on the nutritional implication of feeding on C. laburnoides diet. A comparative analysis on the nutritional and antinutritional factors of raw and blanched leaves of C. laburnoides was carried out using standard analytical methods, where levels of some nutrients and antinutrients were determined. Results obtained showed the percentage (%) moisture contents as 15.25 and 14.90, ash as 8.37 and 9.56, crude fiber as 12.91 and 12.87, crude protein as 7.61 and 10.37, crude fat as 1.41 and 1.64, and carbohydrate as 54.45 and 50.14 for raw and blanched samples respectively. The findings also revealed that β-carotene contents as 10.50 and 7.93 mg/100 g, Vitamin B1 as 1.77 and 1.02 mg/100 g, Vitamin B2 as 7.71 and 1.83 mg/100 g for raw and blanched leaves respectively whereas Vitamin C was not detected in both samples. Mineral analysis revealed that there were high amounts of Calcium as 5999 and 11700 ppm and Manganese 105 and 110 ppm for raw and blanched leaves respectively. Also the findings revealed the presence of metal contaminants (“heavy metals”) in both samples. The contents of antinutritional factors (ANFs); oxalates were 52.94 and 40.0 mg/100g, phytate were 4.30 and 2.02 mg/100g and tannin were 0.115 and 0.073 mg/100g for raw and blanched leaves respectively. The results of this study revealed that C. laburnoides leaves are good nutritionally, containing proximate components, minerals and vitamins in amounts comparable to cultivated species. However, they have high contents of ANFs, but these are reduced significantly (p<0.05) during cooking (as seen in phytate and oxalate in blanched samples), hence cannot prevent their utilization as food sources. This reduction could be accounted by the heat effect/preparation method. Despite the popular consumption and good results presented in this paper, the suitability Crotalaria laburnoides leaves for nutritional purposes will depend on the ongoing toxicity studies.
Architecture Restructuring to Support Evolution towards Service-Oriented Architectures

The evolution of software systems and system land- scapes towards service-oriented architectures is a widely discussed topic. Flexibility is a frequently named goal in this context. To reach this goal, complex information systems that are transfered to service-orientation have to be restructured. In prac- tice the restructuring requires a high manual eort for understanding the existing system and the den- tion of a mapping of its elements to a target architec- ture. Our model-based restructuring approach sup- ports reengineers by semi-automating this task. In this paper we describe how this approach can be ap- plied in the context of the evolution towards a service- oriented architecture.
Stent-Assisted Mechanical Recanalization for Treatment of Acute Intracerebral Artery Occlusions

Background and Purpose— The purpose of this study was to demonstrate a new approach to the use of a self-expanding stent in the treatment of acute ischemic stroke. Methods— Twenty-two consecutive patients with acute intracerebral artery occlusions were treated with a self-expandable intracranial stent, which was withdrawn in its unfolded state. For this technique, we used the Solitaire AB/FR, which is the only intracranial stent that is fully recoverable. Eight patients had an occlusion of the basilar artery, 12 had a middle cerebral artery occlusion, and 2 had terminal carotid artery occlusions; 6 of these had to be treated first for an acute occlusion originating in the internal carotid artery. Recanalization results were assessed by follow-up angiography immediately after the procedure. Neurologic status was evaluated before and after treatment (90-day follow-up) according to the National Institutes of Health Stroke Scale and modified Rankin scale. Results— Successful revascularization was achieved in 20 of 22 (90.9%) patients (thrombolysis in cerebral infarction [TICI] 2a/b and 3), a TICI 3 state was accomplished in 12 patients, and partial recanalization or slow distal branch filling with filling of more than two-thirds of the vessel territory was achieved in 8 patients (TICI 2b). There was immediate flow restoration in 21 of 22 (95.4%) cases after deployment of the device. The stent was removed in its unfolded state in all patients. The mean time from stroke symptom onset to recanalization was 277 minutes, with a standard deviation of 118 minutes. Mean National Institutes of Health Stroke Scale score on admission was 19.4, with a standard deviation of 5.7. Almost two-thirds of the patients (63.6%) improved by >10 points on the National Institutes of Health Stroke Scale at discharge, and 50% showed a modified Rankin scale score of ≤2 at 90 days (59% with a modified Rankin scale ≤3). Mortality was 18.1%. In 1 case, an asymptomatic intracranial hemorrhage was detected on control computed tomography, and 2 patients had a symptomatic intracranial hemorrhage. Conclusion— Withdrawal of an unfolded, fully recoverable, intracranial stent yielded very promising angiographic and clinical results. It combines the advantages of prompt flow restoration and mechanical thrombectomy.
Territorial Product Associations in Greece: The Case of Olive Oil

Abstract The change in emphasis of European food policy toward legislative certification schemes has shifted the research agenda toward investigating the link between the concept of “territory” and food product perceptions. However, a relatively neglected aspect of this literature is the exploratory qualitative work investigating consumer perceptions of “symbolic” and, to a lesser extent, a broader range of “extrinsic” cues within territorial products. More importantly, there is a dearth of equivalent research subjecting these exploratory findings to rigorous quantitative analysis. Accordingly, our paper addresses this weakness in the literature, examining the perceptual inter-relationships between a broad range of intrinsic, extrinsic and symbolic cues by deriving underlying product dimensions. Consumer segments based on these product dimensions are derived and profiled using an array of socio-economic, lifestyle and product knowledge variables. Finally, marketing policy conclusions are drawn.
Using Hidden Markov Models to Determine Cognitive States of Visual Analytic Users

Many visual analytics tools exist to assist users in examining large amounts of information at once via coordinated views that include graphs, network connections and maps. However, the cognitive processes that those users undergo while using such tools remain a mystery. Many psychological studies suggest that individuals may undergo some planning stage followed by analysis before finally making conclusions when examining large amounts of analytical data with the goal of reaching a decision. While the general order of these cognitive states has been theorized, the exact states of individuals at specific points during their interaction with visual analytic systems remain unclear. In this work, we developed models to determine the cognitive states of users based solely on their interactions with visual analytics systems via Hidden Markov Models. Hidden Markov Models allow for the classification of observations through hidden states (cognitive states in our case) as well as the prediction of future cognitive states. We generate these models through unsupervised learning and use established metrics such as AIC and BIC metrics to evaluate our models. Our solutions are designed to help improve visual analytics tools by providing a better understanding of cognitive thought processes of users during data intensive analysis tasks.
Group G streptococcal M protein exhibits structural features analogous to those of class I M protein of group A streptococci

We have previously studied a collection of group G streptococcal strains isolated from bacteremic human infections and demonstrated that such strains resist phagocytosis by human polymorphonuclear leukocytes but are type specifically opsonized by homologous antiserum. We have now performed Southern hybridization analysis on genomic DNA from eight blood isolates. All eight isolates showed DNA homology to a group A emm24 gene probe. The M-protein gene of one of the isolates, strain 1750, has now been isolated. This gene (emmG1) encodes a polypeptide of 67 kDa (MG1) which is reactive with antibodies to the partially purified M protein of the parent strain. The predicted amino acid structure of MG1 demonstrates significant identity with the carboxy terminus (C, D, and anchor domains) of M6 and M24 but only limited identity with the amino terminus (variable portion) of these group A M proteins. Southern hybridization of genomic DNA of the eight group G blood isolates with an emmG1 gene probe indicated there were at least four emm alleles associated with these strains. These studies indicate that M proteins of group G streptococci, like those of group A, are genetically heterogeneous. Moreover, MG1 appears to conform to the recently proposed class I structure of M-protein molecules and thus shares certain distinct structural features with the M proteins of well-established rheumatogenic group A streptococcal serotypes. Further comparison of the structures of group G and group A M proteins of throat and skin isolates may cast light on those configurations of the M protein molecules which are and are not critical for the expression of rheumatogenicity.
Augmented MLFMM for Analysis of Scattering from PEC Object with Fine Structures

─ In this paper, a multilevel Green’s function interpolation method (MLGFIM) combined with multilevel fast multipole method (MLFMM) is presented for solving the electromagnetic scattering from the objects with fine structures. In the conventional MLFMM, the size of the finest cube must be larger than a definite value, which is typically 0.2 λ; it often generates a large number of unknowns in each finest cube especially for objects with fine structures. Accordingly, it requires a lot of memory to store the near-field impedance matrix in MLFMM. In order to decrease the memory requirement of the near-field matrix in the MLFMM, the MLGFIM is introduced to calculate the near-field interactions. The number of unknowns in each cube can be less than a required number regardless of the size of the cube in the MLGFIM. To further reduce the computational complexity, many recompressed techniques, such as the adaptive cross approximation (ACA), QR factorization, and singular value decomposition (SVD), are applied to compress the low rank Green’s function matrix for speeding up the matrix-vector multiplication. Numerical results are given to demonstrate the accuracy and efficiency of the proposed method. Index Terms Multilevel fast multipole method (MLFMM), multilevel Green’s function interpolation method(MLGFIM), QR factorization.
Ontology Extraction from text documents by Singular Value Decomposition ADMI 2001

Due to the abundance of unstructured data available today, it has been interesting to research for finding an automated way to retrieve information, or to respond to a structured or an unstructured query. Domain specific information is useful in processing natural language, information retrieval and systems reasoning. We need more than a simple list of key words for all but very elementary processing. It is very important to build document ontology to analyze a large collection of documents. Ontology of concepts, terms and the relations between concepts is more useful for complex reasoning. This type of ontology if automatically compiled, the user will be freed from all the tedious task of construction and also the ontology will be produced at a greater speed. Basically this project is about constructing a domain specific ontology, by reading the collection of related text documents, and extracting ontological information statistically. In particular, this system determines word frequencies, which are formed into a frequency matrix. Singular Value Decomposition is performed on the frequency matrix, and the resulting matrices are used to determine statistical relationships between documents and terms. These relationships are then used to build an ontological graph. The ontology graph can be viewed and manipulated with graphical user interface (GUI), or loaded into user code. On the whole our system provides a procedure of generating richer domain specific knowledge, with minimal user interaction.
Ju n 20 07 A Wrinkle in Coleman-De Luccia

The decay of a false vacuum in a quantum field theory with the conventional 1 2 (∂μφ) 2 kinetic term was first studied by Coleman[1] via the semiclassical approximation. The effects of gravitation were later included[2]. This work found application in the string landscape, where vacuum decay offers the mechanism by which the multitude of string vacua can be sampled [3]. However, the action appropriate in an open string context has a richer structure than that considered in [1, 2]. We will show that this structure can radically modify the lifetime of certain vacua. To exemplify these modifications, in this letter we consider the case where open string moduli explore the string landscape. Branes and the charges they carry are a crucial part of stable compactifications, and the dynamics of such objects under any process of vacuum selection warrants careful study. In the context of D3 branes probing a type IIB compactification[4] with warp factor 1/f(φ) and potential V (φ)[5], the relevant action is of the Dirac-Born-Infeld (DBI) type. Using this action we will discover two novel features: that the dominant instanton may have a “wrinkle” (see Fig. 2), and that raising the potential barrier can increase the tunneling rate. The net result is that as the barrier height reaches the string scale, the decay rate becomes orders of magnitude faster than the CDL prediction. This effect can be traced to the fact that nucleated bubbles of true vacuum can have parametrically lower domain wall tensions than those arising from the CDL theory. We assume the reader is familiar with the original work by Coleman and De Luccia, which we follow closely.
Information Asymmetry in the Takeover Market

We examine 1,612 acquisitions of publicly listed targets over the period of 1985 – 2006 and test directly how information asymmetry affects the bidding premiums and the announcement returns of the acquirer and the target. Based on several standard proxies for information asymmetry of target firms, we find that the bidding premium is positively correlated with these proxies. We provide explanation for this seemingly counter-intuitive result which is more apparent than real. The information asymmetry proxies also correlate positively with the announcement cumulative abnormal returns (CARs) of the acquirer over the five-day event window. More importantly, notwithstanding the general findings that acquirers earn an average of zero or mildly negative CARs during the takeover announcement period, we observe that the acquirer CARs are positive for the target group at the highest percentile (i.e., highest opacity) in our asymmetry grouping. Apparently, the market rewards acquirers who take in more opaque targets. We also find similar positive relationship of information asymmetry and the announcement returns for target firms. We argue that when the target is more opaque to the market, the takeover announcement has stronger certifying power for the market to re-evaluate the takeover target more favorably.

DETECTION OF CONSERVATIVE CONFORMATIONAL PROPERTIES OF INSERTION SITES FOR DROSOPHILA RETROTRANSPOSONS

Analysis of samples of potential retrotransposon insertion sites for five retrotransposon families (297, 17.6, yoyo, tirant, and roo) has demonstrated that a set of DNA conformational properties within a region of 10 bp from the insertion site center is conserved. The data obtained allow possible molecular mechanisms involved in choosing of the target sites while retrotransposon integration into the host genome to be discussed.
