A Practical q -Gram Index for Text Retrieval Allowing Errors

We propose an indexing technique for approximate text searching, which is practical and powerful, and especially optimized for natural language text. Unlike other indices of this kind, it is able to retrieve any string that approximately matches the search pattern, not only words. Every text substring of a xed length q is stored in the index, together with pointers to all the text positions where it appears. The search pattern is partitioned into pieces which are searched in the index, and all their occurrences in the text are veriied for a complete match. To reduce space requirements, pointers to blocks instead of exact positions can be used, which increases querying costs. We design an algorithm to optimize the pattern partition into pieces so that the total number of veriications is minimized. This is especially well suited for natural language texts, and allows to know in advance the expected cost of the search and the expected relevance of the query to the user. We show experimentally the building time, space requirements and querying time of our index, nding that it is a practical alternative for text retrieval. The retrieval times are reduced from 10% to 60% of the best on-line algorithm.
Augmenting reality for augmented reality

elements that can be integrated with camera-based AR systems but that are independently meaningful objects in their own right. We argue that this new wave of physically grounded AR technologies constitutes the first steps toward a hybridized digital/physical future that can transform our world. The technology space of augmented reality (AR), sometimes characterized using the more general term mixed reality, is one of the more exciting frontiers to emerge from HCI research in recent years [3]. However, like many frontiers, it is chaotic, overhyped, and misunderstood. In the absence of existing best practices to guide development of this new design space, a number of competing visions have taken hold, each of which seeks to colonize the future of our digitally augmented world. Microsoft's version of this future is embodied by the HoloLens, an untethered standalone visor running Windows 10 that superimposes translucent " holographic " overlays into the center of a user's field of view. HoloLens feels like the big brother to Google's Glass project, which traded computing power and graphical fidelity for mobility. Glass was designed to be worn in daily life, a decision that didn't factor in the social consequences of wearing a highly visible digital surveillance There are two competing narratives for the future of computationally augmented spaces. On the one hand, we have the Internet of Things [1], where the narrative is one of making our environments more aware of us and of themselves, and generally making everything " smarter " through embedded computation, sensing, and actuation. On the other hand, we have current approaches to augmented or mixed reality, in which the space remains unchanged and instead we hack our perception of the space by superimposing a layer of media between us and the world [2,3]. In this article we present examples of three projects that seek to merge these two approaches by creating and fabricating playful material
Application of statistical process control in healthcare improvement: systematic review.

OBJECTIVE
To systematically review the literature regarding how statistical process control--with control charts as a core tool--has been applied to healthcare quality improvement, and to examine the benefits, limitations, barriers and facilitating factors related to such application.


DATA SOURCES
Original articles found in relevant databases, including Web of Science and Medline, covering the period 1966 to June 2004.


STUDY SELECTION
From 311 articles, 57 empirical studies, published between 1990 and 2004, met the inclusion criteria.


METHODS
A standardised data abstraction form was used for extracting data relevant to the review questions, and the data were analysed thematically.


RESULTS
Statistical process control was applied in a wide range of settings and specialties, at diverse levels of organisation and directly by patients, using 97 different variables. The review revealed 12 categories of benefits, 6 categories of limitations, 10 categories of barriers, and 23 factors that facilitate its application and all are fully referenced in this report. Statistical process control helped different actors manage change and improve healthcare processes. It also enabled patients with, for example asthma or diabetes mellitus, to manage their own health, and thus has therapeutic qualities. Its power hinges on correct and smart application, which is not necessarily a trivial task. This review catalogs 11 approaches to such smart application, including risk adjustment and data stratification.


CONCLUSION
Statistical process control is a versatile tool which can help diverse stakeholders to manage change in healthcare and improve patients' health.
A Novel design of Electronic Voting System Using Fingerprint

The heart of democracy is voting. The heart of voting is trust that each vote is recorded and tallied with accuracy and impartiality. The accuracy and impartiality are tallied in high rate with biometric system. Among these biometric signs, fingerprint has been researched the longest period of time, and shows the most promising future in real-world applications. Because of their uniqueness and consistency over time, fingerprints have been used for identification over time. However, because of the complex distortions among the different impression of the same finger in real life, fingerprint recognition is still a challenging problem. Hence in this study, the authors are interested in designing and analysing the Electronic Voting System based on the fingerprint minutiae which is the core in current modern approach for fingerprint analysis. The new design is analysed by conducting pilot election among a class of students for selecting their representative. Various analysis predicted shows that the proposed electronic voting system resolves many issues of the current system with the help of biometric technology.

Biotechnological Potential of Agro-Industrial Wastes as a Carbon Source to Thermostable Polygalacturonase Production in Aspergillus niveus

Agro-industrial wastes are mainly composed of complex polysaccharides that might serve as nutrients for microbial growth and production of enzymes. The aim of this work was to study polygalacturonase (PG) production by Aspergillus niveus cultured on liquid or solid media supplemented with agro-industrial wastes. Submerged fermentation (SbmF) was tested using Czapeck media supplemented with 28 different carbon sources. Among these, orange peel was the best PG inducer. On the other hand, for solid state fermentation (SSF), lemon peel was the best inducer. By comparing SbmF with SSF, both supplemented with lemon peel, it was observed that PG levels were 4.4-fold higher under SSF. Maximum PG activity was observed at 55°C and pH 4.0. The enzyme was stable at 60°C for 90 min and at pH 3.0-5.0. The properties of this enzyme, produced on inexpensive fermentation substrates, were interesting and suggested several biotechnological applications.
Imatinib use immediately before stem cell transplantation in children with Philadelphia chromosome-positive acute lymphoblastic leukemia: Results from Japanese Pediatric Leukemia/Lymphoma Study Group (JPLSG) Study Ph+ALL04

Incorporation of imatinib into chemotherapeutic regimens has improved the prognosis of children with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph(+) ALL). We investigated a role of imatinib immediately before hematopoietic stem cell transplantation (HSCT). Children with Ph(+) ALL were enrolled on JPLSG Ph(+) ALL 04 Study within 1 week of initiation of treatment for ALL. Treatment regimen consisted of Induction phase, Consolidation phase, Reinduction phase, 2 weeks of imatinib monotherapy phase, and HSCT phase (Etoposide+CY+TBI conditioning). Minimal residual disease (MRD), the amount of BCR-ABL transcripts, was measured with the real-time PCR method. The study was registered in UMIN-CTR: UMIN ID C000000290. Forty-two patients were registered and 36 patients (86%) achieved complete remission (CR). Eight of 17 patients (47%) who had detectable MRD at the beginning of imatinib monotherapy phase showed disappearance or decrease in MRD after imatinib treatment. Consequently, 26 patients received HSCT in the first CR and all the patients had engraftment and no patients died because of complications of HSCT. The 4-year event-free survival rates and overall survival rates among all the 42 patients were 54.1 ± 7.8% and 78.1 ± 6.5%, respectively. Four of six patients who did achieve CR and three of six who relapsed before HSCT were salvaged with imatinib-containing chemotherapy and subsequently treated with HSCT. The survival rate was excellent in this study although all patients received HSCT. A longer use of imatinib concurrently with chemotherapy should eliminate HSCT in a subset of patients with a rapid clearance of the disease.
The Use of Amnion-Derived Cellular Cytokine Solution (ACCS) in Accelerating Closure of Interstices in Explanted Meshed Human Skin Grafts

UNLABELLED
Meshed, split-thickness skin grafts, especially when required to be widely spread, do not obtain immediate biologic closure. In patients with burns that cover a large percentage of the body surface area, this leaves the patient at risk for metabolic problems and life-threatening infection.


OBJECTIVE
The purpose of this study was to determine whether amnion-derived cellular cytokine solution could improve epithelialization kinetics and accelerate closure of meshed skin graft interstices.


METHODS
Human meshed, split-thickness skin grafts were explanted to athymic "nude" rats and treated with 3 different regimens of amnion-derived cellular cytokine solution (groups I, II, and III) or normal saline (group IV) as a control. Serial wound tracings of unepithelialized interstitial wound areas were compared over time. Two different preparations of amnion-derived cellular cytokine solution were also compared with one another, one containing animal components and the other free of animal components.


RESULTS
Only 67.03% of interstices in control animals closed by day 9. This compared with 92.2% closure for group I, 83.72% for group II, and 90.64% for group III. Interstices in all 3 groups treated with amnion-derived cellular cytokine solution (with or without animal-derived components) closed faster statistically than in the control animals (P < .05). There were no statistical differences among the 3 amnion-derived cellular cytokine solution-treated groups.


CONCLUSIONS
These data suggest that epithelialization kinetics and interstitial closure of meshed skin grafts can be accelerated with the use of amnion-derived cellular cytokine solution, a physiologic cocktail of cytokines, and provide support for a future clinical trial.
Domain Specialization Is Generally Unnecessary for Accelerators

Domain-specific accelerators (DSAs), which sacrifice programmability for efficiency, are a reaction to the waning benefits of device scaling. This article demonstrates that there are commonalities between DSAs that can be exploited with programmable mechanisms. The goals are to create a programmable architecture that can match the benefits of a DSA and to create a platform for future accelerator investigations.
Tumor Consistency of PituitaryMacroadenomas : Predictive Analysis on the Basis of Imaging Features with Contrast-Enhanced 3 D FIESTA at 3 T

BACKGROUND AND PURPOSE: Preoperative evaluation of pituitary macroadenoma tumor consistency is important for neurosurgery. Thus, we aimed to retrospectively assess the role of contrast-enhanced FIESTA in predicting the tumor consistency of pituitary macroadenomas. MATERIALS AND METHODS: Twenty-nine patients with pituitary macroadenomas underwent conventional MR imaging sequences and contrast-enhanced FIESTA before surgery. Two neuroradiologists assessed the contrast-enhanced FIESTA, contrast-enhanced T1WI, and T2WI. On the basis of surgical findings, the macroadenomas were classified by the neurosurgeons as either soft or hard. Finally, Fisher exact probability tests and unpaired t tests were used to compare predictions on the basis of the MR imaging findings with the tumor consistency, collagen content, and postoperative tumor size. RESULTS: The 29 pituitary macroadenomas were classified as either solid or mosaic types. Solid type was characterized by a homogeneous pattern of tumor signal intensity without intratumoral hyperintense dots, whereas the mosaic type was characterized by many intratumoral hyperintense dots on each MR image. Statistical analyses revealed a significant correlation between tumor consistency and contrast-enhanced FIESTA findings. Sensitivity and specificity were higher for contrast-enhanced FIESTA (1.00 and 0.88 – 0.92, respectively) than for contrast-enhanced T1WI (0.80 and 0.25– 0.33, respectively) and T2WI (0.60 and 0.38 – 0.54, respectively). Compared with mosaictype adenomas, solid-type adenomas tended to have a hard tumor consistency as well as a significantly higher collagen content and lower postoperative tumor size. CONCLUSIONS: Contrast-enhanced FIESTA may provide preoperative information regarding the consistency of macroadenomas that appears to be related to the tumor collagen content. ABBREVIATIONS: CE contrast-enhanced; PCC percentage of collagen content; SI signal intensity The transsphenoidal approach of removing pituitary adenomas has been widely adopted as a safe and effective method. Recently, the endoscopic transsphenoidal technique has been applied as a minimally invasive surgery to remove pituitary adenomas. Most pituitary adenomas are soft and thus can be adequately removed by aspiration and curettage via the transsphenoidal route. However, 5–15% of pituitary adenomas are firm and fibrous. This can occur quite often, and, unfortunately, there are no preoperative predictors of its occurrence. Thus, preoperative evaluation of tumor consistency is essential for
DETERMINANTS OF INWARD FDI IN MONGOLIA : AN APPLICATION OF THE ARDL BOUNDS TESTING APPROACH TO COINTEGRATION

The study at hand is the first of its kind that aimed to provide a comprehensive analysis of the determinants of foreign direct investment (FDI) in Mongolia by analyzing their short-run, long-run, and Granger causal relationships. In doing so, we methodically used a series of econometric methods to ensure reliable and robust estimation results that included the augmented Dickey-Fuller and Phillips-Perron unit root tests, the most recently advanced autoregressive distributed lag (ARDL) bounds testing approach to cointegration, fully modified ordinary least squares, and the Granger causality test within the vector error-correction model (VECM) framework. Our findings revealed domestic market size and human capital to have a U-shaped relationship with FDI inflows, with an initial positive impact on FDI in the short-run, which then turns negative in the long-run. Macroeconomic instability was found to deter FDI inflows in the long-run. In terms of the impact of trade on FDI, imports were found to have a complementary relationship with FDI; while exports and FDI were found to be substitutes in the short-run. Financial development was also found to induce a deterring effect on FDI inflows in both the shortand long-run; thereby also revealing a substitutive relationship between the two. Infrastructure level was not found to have a significant impact on FDI on any conventional level, in either the shortor long-run. Furthermore, the results have exhibited significant Granger causal relationships between the variables; thereby, ultimately stressing the significance of policy choice in not only attracting FDI inflows, but also in translating their positive spill-over benefits into long-run economic growth. © 2017 AESS Publications.

Conceptual Business Document Modeling using UN/CEFACT's Core Components

Before two businesses can engage in a business-tobusiness process an agreement about the process execution order and the business documents exchanged in the collaborative process must be found. Although several initiatives from different industries have started standardization initiatives for business documents a set of shortcomings still remain: (1) the different standards do not have a common semantic basis causing inter-operability problems between them and they (2) try to include every possible element any industry might need into the business document standard. (3) Moreover, most of the standards are transfer specific and (4) do not provide a conceptual representation mechanism. In this article a new concept for the standardization of business documents called UN/CEFACT’s Core Components Technical Specification is presented which solves these shortcomings. Using Core Components the business document modeler can unambiguously define documents with a common semantic basis on a conceptual level. In order to allow for a better integration into UML modeling tools we introduce the UML Profile for Core Components. With the UML based core components model and an XML schema generator the modeler can derive XML schema artifacts from the conceptual model.
Survey and behavioral measurements of interpersonal trust

Please cite this article in press as: Evans, Journal of Research in Personality (2008), Although many studies treat trust as a situational construct, individual differences can be used to study and predict trusting behavior. We report two studies, the first showing the psychometric properties of a new trust inventory (the Propensity to Trust Survey or PTS), the second study validating this inventory using the standard economic task, the Investment Game. The first study utilized online survey data (N > 8000) to show that the PTS scales were reliable and measured broad constructs related to Big Five personality domains. Trust was related to extraversion and negative neuroticism, and trustworthiness was related to agreeableness and conscientiousness. The second study (N = 90) validated the PTS trust scale as a predictor of behavior in the Investment Game. These findings are evidence that trust and trustworthiness are compound personality traits, and that PTS scales are preferable to general Big Five measures for predicting trusting behavior. 2008 Elsevier Inc.

How and how not to correct for CSF-contamination in diffusion MRI

Diffusion MRI is used extensively to investigate changes in white matter microstructure related to brain development and pathology. Ageing, however, is also associated with significant white and grey matter loss which in turn can lead to cerebrospinal fluid (CSF) based partial volume artefacts in diffusion MRI metrics. This is especially problematic in regions prone to CSF contamination, such as the fornix and the genu of corpus callosum, structures that pass through or close to the ventricles respectively. The aim of this study was to model the effects of CSF contamination on diffusion MRI metrics, and to evaluate different post-acquisition strategies to correct for CSF-contamination: Controlling for whole brain volume and correcting on a voxel-wise basis using the Free Water Elimination (FWE) approach. Using the fornix as an exemplar of a structure prone to CSF-contamination, corrections were applied to tract-specific and voxel-based [tract based spatial statistics (TBSS)] analyses of empirical DT-MRI data from 39 older adults (53-93 years of age). In addition to significant age-related decreases in whole brain volume and fornix tissue volume fraction, age was also associated with a reduction in mean fractional anisotropy and increase in diffusivity metrics in the fornix. The experimental data agreed with the simulations in that diffusivity metrics (mean diffusivity, axial and radial diffusivity) were more prone to partial volume CSF-contamination errors than fractional anisotropy. After FWE-based voxel-by-voxel partial volume corrections, the significant positive correlations between age and diffusivity metrics, in particular with axial diffusivity, disappeared whereas the correlation with anisotropy remained. In contrast, correcting for whole brain volume had little effect in removing these spurious correlations. Our study highlights the importance of correcting for CSF-contamination partial volume effects in the structures of interest on a voxel-by-voxel basis prior to drawing inferences about underlying changes in white matter structures and have implications for the interpretation of many recent diffusion MRI results in ageing and disease.
A general model of accounting information systems

Accounting information system composes the most important part in management information systems because accounting is stated as the language of a management. Thereby, accounting information obtained from accounting information system is a kind of basic knowledge for the efficient management system. In particular, data gained from the accounting system with computer base ensures extremely important contributions for the management systems to be successful. In this study, the development of accounting information system and its significance for the managements are examined generally.
All the news that's fit to post: A profile of news use on social networking sites

Facebook and other social networking sites (SNSs) are altering the way individuals communicate. These online environments allow users to keep up with friends, network with colleagues, and share their personal views and observations with others. Previous work describes typical social networking site users as young, extroverted, and technologically savvy. Little research exists, however, on the emerging role of news in the social network environment. With over 500 million global Facebook users, both print and television based media outlets are making concerted efforts to become part of this important and increasingly ubiquitous virtual world. The present study uses a sample of students, faculty, and staff from a large university to investigate the factors that are related to news use on Facebook. Findings indicate that while news use is still a minor component of overall social network site activity, certain key variables, such as gender and life satisfaction, have a significant impact on how Facebook is used for news-related purposes. Future implications for news in the social networking world are presented and discussed. 2011 Elsevier Ltd. All rights reserved.
