The Power of Local Consistency in Conjunctive Queries and Constraint Satisfaction Problems

Answering conjunctive queries is a fundamental problem in database theory, and it is equivalent to solving constraint satisfaction problems in artificial intelligence and to other fundamental problems arising in computer science, which can be recast in terms of looking for homomorphisms between relational structures. The problem is NP-hard, so that several research efforts have been made in the literature for identifying tractable classes, known as islands of tractability, as well as for devising clever heuristics for solving efficiently real-world instances. Many heuristic approaches are based on enforcing on the given instance a property called local consistency (also, relational arc-consistency), where each tuple in every query atom matches at least one tuple in every other query atom. Interestingly, for many well-known classes of instances, such as for the acyclic ones, enforcing local consistency is even sufficient to solve the given instance correctly. However, the precise power of such a procedure .
The occurrence of rare motile bacteria in some non-motile Salmonella strains.

SUMMARY: The presence of rare motile bacteria in 22 of 48 non-motile Salmonella strains tested has been inferred from the production of satellite micro-colonies in semi-solid medium. Such rare motile bacteria have been isolated by micromanipulation; they are not motile mutants, since their progeny are nearly all non-motile. They transmitted motility to only a few of their descendants, as if their motility were due to the presence of non-multiplying motility-conferring particles which were transmitted to their progeny at cell division. It is inferred that small numbers of such particles arise during an intracellular ‘event’; this event probably consists of a transient ability to synthesize new flagella. The frequency of events in one Salmonella O strain was found to be c. 4 x 10-5/bacterium/generation.
Behavioral Outcomes of Supervisory Education in the Association for Clinical Pastoral Education: A Qualitative Research Study

This study advances the work of developing a theory for educating Clinical Pastoral Education (CPE) Supervisors by describing the behaviors which result from the successful completion of CPE supervisory education. Twenty-eight Association for Clinical Pastoral Education (ACPE) Certification Commissioners were interviewed to identify the behaviors demonstrated by Supervisory Education Students (Candidates) which influenced the decision to certify them at the level of Associate Supervisor. Specific behavioral descriptors are listed for each ACPE supervisory competency
The multiple-faces configuration illusion in schizophrenic patients

The Multiple-Faces Configuration Illusion is observed by staring at a black dot while paying attention to a face in the peripheral visual field (Simas, 2000). Changes of facial expressions, movements, depth (EMF) or different face identities (MF) are observed in this illusion. Forty participants took part in the study: 20 outpatients diagnosed with schizophrenia, and 20 people helping friends or relatives in a hospital clinic. The face-stimulus was placed in a partition stand and participants instructed to describe any visual event occurring during 90 s, one eye at a time. Results showed that 100% of women in the experimental group (EG) reported perceiving events related to MF with the left eye. Significantly fewer women saw these events with the right eye. Also, fewer men in the experimental group and men and women in the control group saw these events with either eye.
Effect of multiple visual feedbacks for text entry on touch screen

A large amount of study about multisensory feedback for touch screen has been conducted, but multiple unisensory feedback has not. In this study, we investigated both objective and subjective evaluation of multiple visual feedbacks on touch screen. We presented two different visual feedbacks, either alone or combined, for QWERTY text entry. The results showed that the subjective evaluation of visual feedback 1 (Button feedback) was positive, while another visual feedback (Ripples) does not have any effect on evaluations. However, there was significant interaction between the two visual feedbacks. The effect of Button feedback was reduced while Ripples was provided. One possible explanation is that Ripples may not be appropriate for this task. Thus participants might ignore the Ripples feedback. Another is that multiple unisensory feedback might be too complicated, because these visual feedbacks overlap each other and moreover have different information.

India is a known mega-biodiversity centre harbouring a multitude of medicinal plant species. Out of an estimated 17,000 higher plant species occurring in India, more than 1500 species are used over several centuries in the traditional systems of medicine viz. Ayurveda, Siddha, Unani and Amchi. The villagers and tribal folks spread across the length and breadth of the country make use of more than 7000 plant species through oral traditions (1). Nearly 3/4 of the herbal drugs and perfumery products used in the world are available in natural state in India. Therefore, the rich and varied species and genetic diversity of medicinal and aromatic plants, is one of India's important strengths and is the bedrock for all future bioindustrial developments.
CLAS at the MediaEval 2015 C@merata Task

The CLAS 2015 system treats the C@merata task as a Q&A problem specified with a controlled language. In this year’s system, we added a context-free grammar for the music controlled language using the Natural Language ToolKit. Crucially this provides an in-built feature unification mechanism allowing us to replace the ad-hoc unification component in the 2014 system. The CLAS 2015 system with this modification finished first in the C@merata shared task. In this paper, we describe the approach behind our participation in the shared task and discuss arguments for and against using a feature-based context-free grammar to parse queries.
A Step toward Personalized Social Geotagging

In this paper, we propose a framework for personalized access to location-aware services. The system relies on the integration of a Geographic Information Retrieval module with a User Modeling component. We describe an application into a specific field, but the platform is easily usable in different contexts. Currently, the framework has been extending to the mobile domain. Author Keywords
Plant-Insect Interactions from Early Permian (Kungurian) Colwell Creek Pond, North-Central Texas: The Early Spread of Herbivory in Riparian Environments

Premise of research. Two previous studies examined the extent of insect herbivory in Early Permian habitats of north-central Texas, with varying results indicating minimal to modest levels of interaction diversity. In a comparison to two previous floras, we tested whether herbivory patterns in a third, slightly younger, assemblage, the Colwell Creek Pond (CCP) flora, most closely reflect plant host taxonomic affiliation, plant conspicuousness, habitat, geologic time, or other variable. Methodology. We assessed the diversity and frequency of insect herbivory on 2140 specimens at CCP. We examined the percent of leaf area removed by herbivory as a third, independent, measure of the effect of insect herbivore removal of host plant photosynthetic tissue. Pivotal results. In a moderately diverse flora of 12 taxa, we found evidence for hole feeding, margin feeding, surface feeding, piercing and sucking, oviposition, galling, seed predation, and wood boring. Some damage was fungally modified. Three herbivory measures consistently indicate that the two overwhelmingly herbivorized taxa were Auritifolia waggoneri, a peltasperm, and Taeniopteris spp. , a form genus of unknown affinity. An approximate order of magnitude less herbivory was present for Evolsonia texana, a gigantopterid; indeterminate broad-leaved seed plants, possibly including a mixoneuroid odontopteroid and Rhachiphyllum; and Walchia piniformis, a conifer. A notable association occurred between W. piniformis and an aldegid hemipteran scale insect or precursor lineage. The remaining eight taxa displayed little or no herbivory. About 5% of seeds showed evidence for predation. Conclusions. Herbivory dominance on A. waggoneri and Taeniopteris spp. at CCP supports a hypothesis that the early expansion of herbivory in clastic depositional settings tracked broad-leaved seed plants, a pattern likely modified by other factors, such as conspicuousness. Insects targeted particular host plants and were specialists on certain foliar tissue types, such as galling on A. waggoneri and oviposition on Taeniopteris spp.
Validity of a trunk-mounted accelerometer to assess peak accelerations during walking, jogging and running

Abstract The purpose of this study was to validate peak acceleration data from an accelerometer contained within a wearable tracking device while walking, jogging and running. Thirty-nine participants walked, jogged and ran on a treadmill while 10 peak accelerations per movement were obtained (n = 390). A single triaxial accelerometer measured resultant acceleration during all movements. To provide a criterion measure of acceleration, a 12-camera motion analysis (MA) system tracked the position of a retro-reflective marker affixed to the wearable tracking device. Peak raw acceleration recorded by the accelerometer significantly overestimated peak MA acceleration (P < 0.01). Filtering accelerometer data improved the relationship with the MA system (P < 0.01). However, only the 10 Hz and 8 Hz cut-off frequencies significantly reduced the errors found. The walk movement demonstrated the highest accuracy, agreement and precision and the lowest relative errors. Linear increases in error were observed for jog compared with walk and for run compared to both other movements. As the magnitude of acceleration increased, the strength of the relationship between the accelerometer and the criterion measure decreased. These results indicate that filtered accelerometer data provide an acceptable means of assessing peak accelerations, in particular for walking and jogging.
Breakdown Analysis of Magnetic Flip-Flop With 28-nm UTBB FDSOI Technology

Dielectric breakdown behaviors of high-performance nonvolatile magnetic flip-flop (NV-MFF) are investigated in this paper. Hybrid magnetic-CMOS flip-flop is implemented based on the spin torque transfer magnetic tunnel junction (MTJ) and 28-nm ultrathin body and buried oxide fully depleted silicon-on-insulator (FDSOI) technology. Transistor high-κ metal-gate dielectric stacks and MTJ oxide barrier (MgO) are impacted by time-dependent oxide breakdown, which is shown by circuit-level characterizations: soft-breakdown as performance fluctuation/ degradation and hard-breakdown as functional failure. We present the cumulative distribution of breakdown probability of both FDSOI CMOS transistors and MTJ devices. The traditional ohmic breakdown model is applied to evaluate circuit sensitivity to breakdown events. A quantitative analysis is performed considering the breakdown spots in the NV-MFF circuit. The increased gate current density (ΔIg/WL) aggravates breakdown severity. Simulation results demonstrate both soft and hard breakdown behaviors in different building blocks, e.g., latency degradation in sense amplifier and output level degradation in other digital circuits. Results show that the oxide breakdown in the NV-MFF circuit is in accordance with the weakest link characteristic, as well as the area dependence.
In vitro anti-microbial activity of extracts from the callus cultures of some Nigella species

Crude methanol extracts from callus cultures of Nigella arvensis, N. damascena, N. hispanica, N. integrifolia, and N. sativa were investigated for their anti-microbial activity. Growth inhibition was determined in Gram-positive and Gram-negative bacterial strains as well as in yeast by using a broth-microdilution method. The results showed that the extracts of all calli tested exhibited significant anti-microbial activity, especially against Bacillus cereus, Staphylococcus aureus and Staphylococcus epidermidis. Compared with other Nigella species, a callus culture of N. hispanica was the most effective against the microorganisms used in this study.
A novel logic level calculation model for leakage currents in digital nano-CMOS circuits

Accurate leakage current estimation in the early phase of digital IC synthesis is an increasingly critical step in the design flow. We present a logic-level estimation approach, suitable for implementation in HDL models or as an off-line tool, supporting separate estimation of the leakage components (sub-threshold, gate tunneling, reverse junction BTBT) including pattern dependency, stacking effects and loading effects. Results on single standard cells and multi-cell circuits exhibit a very good accuracy i.e. below 1% error with respect to Spice BSIM4.
DC-DC Power Converter with digital PID controller

This paper presents an approach for an adaptive PID controller in order to improve the dynamic performance of DC-DC Power Converter. The control variables, namely the proportional constant (Kp) and integral constant (Ki) are varied as a function of the uncompensated error voltage which results in improving the dynamic transient response of the power converter. The experimental results show that there is a reduction in overshoot/undershoot and settling time compared to the conventional PID.
Superlensing Microscope Objective Lens

Conventional microscope objective lenses are diffraction limited; they cannot resolve subdiffraction features of size smaller than 250-300 nm under white lighting condition. New innovations are required to overcome such limit. In this paper, we propose and demonstrate a new superlensing objective lens which possesses a resolution of 100 nm, offering two times resolution improvement over conventional objectives. This is accomplished by integrating a conventional microscope objective lens with a superlensing microsphere lens using a customized lens adaptor. The new objective lens was successfully demonstrated for label-free super-resolution imaging of 100 nmfeatures in engineering and biological samples, including a Blu-ray disc sample and adenoviruses. Our work opens a new door to develop a generic optical superlens, which may transform the field of optical microscopy and imaging.
Creativity and Innovation in Health Care: Tapping Into Organizational Enablers Through Human-Centered Design

There is an increasing drive in health care for creativity and innovation to tackle key health challenges, improve quality and access, and reduce harm and costs. Human-centered design (HCD) is a potential approach to achieving organizational innovation. However, research suggests the nursing workforce feels unsupported to take the risks needed for innovation, and leaders may not understand the conditions required to fully support them. The aim of this study was to identify enabling conditions that support frontline nurses in their attempts to behave as champions of innovation and change. An HCD workshop was undertaken with 125 nurses employed in clinical practice at Kaiser Permanente. The workshop included empathy mapping and semistructured questions that probed participant experiences with innovation and change. The data were collated and thematic analysis undertaken through a Grounded Theory approach. The data were analyzed to identify key enabling conditions. Seven enablers emerged: personal need for a solution; challenges that have meaningful purpose; clarity of goal and control of resources; active experimentation; experiences indicating progress; positive encouragement and confidence; and provision of psychological safety. These enablers were then translated into pragmatic guidelines for leaders on how the tools of HCD may be leveraged for innovation and change in health care.
Place recognition and automatic semantic annotation via the Whereabouts diary

Purpose – Modern handheld devices provided with localization capabilities can create a diary of the user whereabouts, and provide a description of the user habits and a complement of the user profile in several applications. The places we go, in fact, reveal something about us; for example, two persons can be matched as compatible given the fact that they visit the same places. The purpose of this paper is to describe the Whereabouts diary in this context.Design/methodology/approach – This paper presents the Whereabouts diary, an application/service to log the places visited by the user and to label them, in an automatic way, with descriptive semantic information. Web‐retrieved information, and the temporal patterns with which different places are visited, can be used to automatically define meaningful semantic labels to the visited places.Findings – The paper verified that such diary application can be created and can effectively classify the places visited by the user. In particular, geocoding and white.
Rapid Diagnosis of Ebola Hemorrhagic Fever by Reverse Transcription-PCR in an Outbreak Setting and Assessment of Patient Viral Load as a Predictor of Outcome

ABSTRACT The largest outbreak on record of Ebola hemorrhagic fever (EHF) occurred in Uganda from August 2000 to January 2001. The outbreak was centered in the Gulu district of northern Uganda, with secondary transmission to other districts. After the initial diagnosis of Sudan ebolavirus by the National Institute for Virology in Johannesburg, South Africa, a temporary diagnostic laboratory was established within the Gulu district at St. Mary's Lacor Hospital. The laboratory used antigen capture and reverse transcription-PCR (RT-PCR) to diagnose Sudan ebolavirus infection in suspect patients. The RT-PCR and antigen-capture diagnostic assays proved very effective for detecting ebolavirus in patient serum, plasma, and whole blood. In samples collected very early in the course of infection, the RT-PCR assay could detect ebolavirus 24 to 48 h prior to detection by antigen capture. More than 1,000 blood samples were collected, with multiple samples obtained from many patients throughout the course of infection. Real-time quantitative RT-PCR was used to determine the viral load in multiple samples from patients with fatal and nonfatal cases, and these data were correlated with the disease outcome. RNA copy levels in patients who died averaged 2 log10 higher than those in patients who survived. Using clinical material from multiple EHF patients, we sequenced the variable region of the glycoprotein. This Sudan ebolavirus strain was not derived from either the earlier Boniface (1976) or Maleo (1979) strain, but it shares a common ancestor with both. Furthermore, both sequence and epidemiologic data are consistent with the outbreak having originated from a single introduction into the human population.
Immediate Load Protocol for Anterior Maxilla With Cortical Bone From Mandibular Ramus

Objective:To evaluate the concept of a nonfunctional immediate load protocol with single implants placed in the anterior maxilla that has been bone grafted with autogenous, block cortical grafts harvested from the ramus of the mandible. Methods:There were 19 hydroxyapatite-coated dental implants surgically placed in 19 patients, and immediately loaded between 48 hours and 3 days later with a custom acrylic provisional restoration that was placed out of functional occlusion. After 12 weeks, the definitive ceramo metal restoration was cemented to the custom abutment. Results:Over a 1-year observation period, all implants continue to function. Conclusion:The preliminary results of this clinical study indicate that immediate, nonfunctional load with single implants is a predictable protocol in the bone grafted anterior maxilla in select cases.
Two different lymph node metastatic patterns of a prostatic cancer

Among 753 autopsy prostatic cancer cases with a metastasis, 476 (63%) had a lymph node metastasis, whereas 277 (37%) did not. Two different lymph node metastatic patterns were observed: Type 1, combined metastasis involving the pelvic and paraaortic lymph nodes; and Type 2, metastasis to the paraaortic lymph nodes, but not to the pelvic lymph nodes. Type 1 metastasis cases showed a significantly more frequent metastasis to the bladder and rectum, and a less frequent metastasis to the lungs and liver. Hydronephrosis occurred more frequently (P < 0.01) in the Type 1. Furthermore, in the Type 1 cases the lymph node metastasis appeared to be continuously invasive, but in the Type 2 cases, metastasis appeared to be the skip type or some metastases may have spread via the vertebral vein bypass route and may have been associated with a hematogenous metastasis.
Early versus delayed pulmonary rehabilitation: A randomized controlled trial – Can we do it?

Providing outpatient pulmonary rehabilitation (PR) following hospitalization for an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) has been found to improve exercise capacity, quality of life and a reduction in unplanned hospital admissions and mortality.1 These positive effects, although studied in the short term, have led to national and international guidelines supporting the provision of post-exacerbation PR (PEPR). 2,3 However, uptake is poor with less than 10% of hospital discharges for AECOPD completing PEPR.4 We therefore considered whether it would be effective to delay PR for patients who have recently been hospitalized for their AECOPD.
Machine learning based cascaded ANN MPPT controller for erratic PV shading circumstances

Power generation is challenged to meet energy demand during peak hours. As a result of limited non-renewable energy resources, power utilities heavily rely on fossil fuels. Therefore, scientists and researchers are looking for some distributed generators to provide additional power during peak hours. During such period, load demand is solved using solar power. As a consequence, grid-connected solar Photovoltaic (PV) systems are catching the attention owing to their ability to significantly reduce the use of fossil fuels. Under Partial Shading Condition (PSC), this paper utilizes Luo Converter along with Cascaded Artificial Neural Network (ANN), which is a Machine Learning Based Maximum Power Point Tracking (ML-MPPT) approach for tracking optimal power from PV system. The gained DC supply is converted into AC voltage using VSI attached to the system. In addition, PI controller engaged controls the voltage at grid side and results in effective grid synchronization. Furthermore, MATLAB Simulink analysis is carried out and the outcomes reveal the effectiveness of proposed system with 98% efficiency under different PV circumstances.
Comorbidity among anxiety disorders: implications for treatment and DSM-IV.

Research on comorbidity among psychological disorders is relatively new. Yet, comorbidity data have fundamental significance for classification and treatment. This significance is particularly apparent in the anxiety disorders, which, prior to DSM-III-R, were subsumed under disorders considered more significant (e.g., psychotic and depressive disorders). After considering definitional, methodological, and theoretical issues of comorbidity, data on comorbidity among the anxiety disorders are reviewed as well as data on comorbidity of anxiety disorders with the depressive, personality, and substance use disorders. Treatment implications are presented with preliminary data on the effects of psychosocial treatment of panic disorder on co-morbid generalized anxiety disorder. Implications of comorbidity for research on the nature of psychopathology and the ultimate integration of dimensional and categorical features in our nosology are considered.
