CONTENT-BASED IMAGE RETRIEVAL FOR ASSET MANAGEMENT BASED ON WEIGHTED FEATURE AND K-MEANS CLUSTERING

Assets have different shapes, colors and textures. A shape feature is the main characteristic, which distinguishes each type of asset in addition to the other features, i.e. the color and the texture. The value of features in the image-based asset information retrieval is used as the key field by comparing the similarities between the images. These similarities can be determined based on the differences in the feature values of query images and the images in the database. The closer to zero the difference, the higher the degree of similarities. The degree of similarities will affect the accuracy level of the image retrieval. In this research, image retrieval accuracy and computing time measurement were analyzed. The retrieval accuracy could improve using the property-weighting scheme of weighted features. Moment invariants, color moments and statistical texture are selected to representation shape, color and texture feature. Preprocessing before extraction was done through grayscale, resizing, edge enhancement, histogram equalization. Image asset data clustering was done using K-Means clustering. The research findings suggest that the retrieval accuracy with a total of 400 asset-image data is more than 95% for weighting scheme of Ws (weighted shape) = 50%, Wc (weighted color) = 30%, Wt (weighted texture) = 20% and 10 clusters with the average computing time of 5 millisecond.
The Use of Electroencephalography in Language Production Research: A Review

Speech production long avoided electrophysiological experiments due to the suspicion that potential artifacts caused by muscle activity of overt speech may lead to a bad signal-to-noise ratio in the measurements. Therefore, researchers have sought to assess speech production by using indirect speech production tasks, such as tacit or implicit naming, delayed naming, or meta-linguistic tasks, such as phoneme-monitoring. Covert speech may, however, involve different processes than overt speech production. Recently, overt speech has been investigated using electroencephalography (EEG). As the number of papers published is rising steadily, this clearly indicates the increasing interest and demand for overt speech research within the field of cognitive neuroscience of language. Our main goal here is to review all currently available results of overt speech production involving EEG measurements, such as picture naming, Stroop naming, and reading aloud. We conclude that overt speech production can be successfully studied using electrophysiological measures, for instance, event-related brain potentials (ERPs). We will discuss possible relevant components in the ERP waveform of speech production and aim to address the issue of how to interpret the results of ERP research using overt speech, and whether the ERP components in language production are comparable to results from other fields.
The diversity, ecology and evolution of extrafloral nectaries: current perspectives and future challenges.

BACKGROUND Plants in over one hundred families in habitats worldwide bear extrafloral nectaries (EFNs). EFNs display a remarkable diversity of evolutionary origins, as well as diverse morphology and location on the plant. They secrete extrafloral nectar, a carbohydrate-rich food that attracts ants and other arthropods, many of which protect the plant in return. By fostering ecologically important protective mutualisms, EFNs play a significant role in structuring both plant and animal communities. And yet researchers are only now beginning to appreciate their importance and the range of ecological, evolutionary and morphological diversity that EFNs exhibit. SCOPE This Highlight features a series of papers that illustrate some of the newest directions in the study of EFNs. Here, we introduce this set of papers by providing an overview of current understanding and new insights on EFN diversity, ecology and evolution. We highlight major gaps in our current knowledge, and outline future research directions. CONCLUSIONS Our understanding of the roles EFNs play in plant biology is being revolutionized with the use of new tools from developmental biology and genomics, new modes of analysis allowing hypothesis-testing in large-scale phylogenetic frameworks, and new levels of inquiry extending to community-scale interaction networks. But many central questions remain unanswered; indeed, many have not yet been asked. Thus, the EFN puzzle remains an intriguing challenge for the future.
Feedback-based event-driven parts moving

A collection of unactuated disk-shaped "parts" must be brought by an actuated manipulator robot into a specified configuration from arbitrary initial conditions. The task is cast as a noncooperative game played among the parts-which in turn yields a feedback-based event-driven approach to plan generation and execution. The correctness of this approach, an open question, has been demonstrated in simpler settings and is further suggested by the extensive experiments reported here using an actual working implementation with EDAR-a mobile robot operating in a purely feedback-based event-driven manner. These results verify the reliability of this approach against uncertainties in sensory information and unanticipated changes in workspace configuration.
YcfR (BhsA) Influences Escherichia coli Biofilm Formation through Stress Response and Surface Hydrophobicity

ABSTRACT DNA microarrays revealed that expression of ycfR, which encodes a putative outer membrane protein, is significantly induced in Escherichia coli biofilms and is also induced by several stress conditions. We show that deletion of ycfR increased biofilm formation fivefold in the presence of glucose; the glucose effect was corroborated by showing binding of the cyclic AMP receptor protein to the ycfR promoter. It appears that YcfR is a multiple stress resistance protein, since deleting ycfR also rendered the cell more sensitive to acid, heat treatment, hydrogen peroxide, and cadmium. Increased biofilm formation through YcfR due to stress appears to be the result of decreasing indole synthesis, since a mutation in the tnaA gene encoding tryptophanase prevented enhanced biofilm formation upon stress and adding indole prevented enhanced biofilm formation upon stress. Deleting ycfR also affected outer membrane proteins and converted the cell from hydrophilic to hydrophobic, as well as increased cell aggregation fourfold. YcfR seems to be involved in the regulation of E. coli K-12 biofilm formation by decreasing cell aggregation and cell surface adhesion, by influencing the concentration of signal molecules, and by interfering with stress responses. Based on our findings, we propose that this locus be named bhsA, for influencing biofilm through hydrophobicity and stress response.
Mindfulness-based cognitive therapy for people with chronic fatigue syndrome still experiencing excessive fatigue after cognitive behaviour therapy: a pilot randomized study.

UNLABELLED Cognitive behaviour therapy (CBT) is an effective treatment for chronic fatigue syndrome (CFS; sometimes known as myalgic encephalomyelitis). However, only a minority of patients fully recover after CBT; thus, methods for improving treatment outcomes are required. This pilot study concerned a mindfulness-based cognitive therapy (MBCT) intervention adapted for people with CFS who were still experiencing excessive fatigue after CBT. The study aimed to investigate the acceptability of this new intervention and the feasibility of conducting a larger-scale randomized trial in the future. Preliminary efficacy analyses were also undertaken. Participants were randomly allocated to MBCT or waiting list. Sixteen MBCT participants and 19 waiting-list participants completed the study, with the intervention being delivered in two separate groups. Acceptability, engagement and participant-rated helpfulness of the intervention were high. Analysis of covariance controlling for pre-treatment scores indicated that, at post-treatment, MBCT participants reported lower levels of fatigue (the primary clinical outcome) than the waiting-list group. Similarly, there were significant group differences in fatigue at 2-month follow-up, and when the MBCT group was followed up to 6 months post-treatment, these improvements were maintained. The MBCT group also had superior outcomes on measures of impairment, depressed mood, catastrophic thinking about fatigue, all-or-nothing behavioural responses, unhelpful beliefs about emotions, mindfulness and self-compassion. In conclusion, MBCT is a promising and acceptable additional intervention for people still experiencing excessive fatigue after CBT for CFS, which should be investigated in a larger randomized controlled trial. KEY PRACTITIONER MESSAGE Only about 30% of people with chronic fatigue syndrome (CFS) recover after cognitive behaviour therapy (CBT); thus, methods for improving treatment outcomes are needed. This is the first pilot randomized study to demonstrate that a mindfulness-based intervention was associated with reduced fatigue and other benefits for people with CFS who were still experiencing excessive fatigue after a course of CBT. Levels of acceptability, engagement in the intervention and rated helpfulness were high. A larger-scale randomized controlled trial is required.
Cadaveric Study of Profunda Femoris Artery with Some Unique Variations.

BACKGROUND Profunda femoris artery is the largest branch of femoral artery and chief supply of the thigh. It is useful for various clinical procedures like arteriography, ultrasonography and Doppler imaging and haemodialysis. Hence, accurate anatomical knowledge is very important for the clinicians. MATERIALS AND METHODS Thirty three properly embalmed cadavers (17 males and 16 females) were selected for the study. Femoral artery, Profunda femoris artery and its branches were exposed and their distances of origin were measured. RESULTS In present study of profunda femoris artery, we found posterolateral and lateral aspect of origin was common (71.21%) than posterior and posteromedial aspect of origin (24.24%). The site of origin of profunda femoris artery was between 21-40 mm on right side and 11-40 mm on left side. In 14 limbs (21.21%), we found high origin of profunda femoris artery (distance < 10mm). In two limbs (3.03%) Profunda femoris artery was originating from medial side of femoral artery and it coursed superficial to femoral vein. As per various literatures this is rare. In one female cadaver, on left side, we noted high origin (5mm away from mid inguinal point) of profunda femoris artery and site of origin was from anterolateral aspect of femoral artery and all the superficial branches of thigh took origin from it, while on right side of same cadaver findings were normal. In 13 limbs (19.69%) profunda femoris artery took origin as a common stem along with one of circumflex arteries while in three limbs (4.54%) trifurcation was observed, that is origin of profunda femoris and two circumflex arteries from single site. In four limbs (6.06%), superficial branches of femoral artery took origin from profunda femoris artery instead of femoral artery. CONCLUSION In present study posterolateral and lateral side of origin is noted as common site of origin of profunda femoris artery. Rare variation like medial side origin of profunda Femoris artery was observed and it coursed on femoral vein. Very high incidence of high level of origin of profunda femoris artery was found. In one of the high origin limb profunda femoris artery originated from anterolateral side and all superficial branches of thigh took origin from it. Such variation is unique. Hence, this study will help the clinicians to avoid iatrogenic complications and also help them in various clinical procedures like puncture of femoral artery for interventional radiology.
From HCI to HCI-Amusement: Strategies for Engaging what New Technology Makes Old

Notions of what counts as a contribution to HCI continue to be contested as our field expands to accommodate perspectives from the arts and humanities. This paper aims to advance the position of the arts and further contribute to these debates by actively exploring what a "non-contribution" would look like in HCI. We do this by taking inspiration from Fluxus, a collective of artists in the 1950's and 1960's who actively challenged and reworked practices of fine arts institutions by producing radically accessible, ephemeral, and modest works of "art-amusement. " We use Fluxus to develop three analogous forms of "HCI-amusements," each of which shed light on dominant practices and values within HCI by resisting to fit into its logics.
Channel Estimation Using Frequency-domain Superimposed Pilot Time-Domain Correlation Method for OFDM Systems

This paper proposes a new channel estimation method based on frequency-domain superimposed pilot time-domain correlation (FSPTC) for orthogonal frequency division multiplexing (OFDM) systems. In this scheme, pilots are directly added on information symbols in frequency-domain at the transmitter without consuming extra bandwidth. At the receiver, we acquire the coarse estimation of channel and information symbols through the correlation between the known pilots and the received signals. More accurate estimation is obtained by iterative operations, which eliminate the effect of unknown information symbols on pilot correlation. The effect of parameters-total number of sub-carriers, the pilot period and the pilot power ratio-on estimation performance is discussed in theory and simulation. The simulation results show that the system performance of our proposed scheme is approximate to the performance under the situation of ideal channel state information (CSI).
Effect of 2 Years of Treatment With Sublingual Grass Pollen Immunotherapy on Nasal Response to Allergen Challenge at 3 Years Among Patients With Moderate to Severe Seasonal Allergic Rhinitis: The GRASS Randomized Clinical Trial

Importance Sublingual immunotherapy and subcutaneous immunotherapy are effective in seasonal allergic rhinitis. Three years of continuous treatment with subcutaneous immunotherapy and sublingual immunotherapy has been shown to improve symptoms for at least 2 years following discontinuation of treatment. Objective To assess whether 2 years of treatment with grass pollen sublingual immunotherapy, compared with placebo, provides improved nasal response to allergen challenge at 3-year follow-up. Design, Setting, and Participants A randomized double-blind, placebo-controlled, 3–parallel-group study performed in a single academic center, Imperial College London, of adult patients with moderate to severe seasonal allergic rhinitis (interfering with usual daily activities or sleep). First enrollment was March 2011, last follow-up was February 2015. Interventions Thirty-six participants received 2 years of sublingual immunotherapy (daily tablets containing 15 µg of major allergen Phleum p 5 and monthly placebo injections), 36 received subcutaneous immunotherapy (monthly injections containing 20 µg of Phleum p 5 and daily placebo tablets) and 34 received matched double-placebo. Nasal allergen challenge was performed before treatment, at 1 and 2 years of treatment, and at 3 years (1 year after treatment discontinuation). Main Outcomes and Measures Total nasal symptom scores (TNSS; range; 0 [best] to 12 [worst]) were recorded between 0 and 10 hours after challenge. The minimum clinically important difference for change in TNSS within an individual is 1.08. The primary outcome was TNSS comparing sublingual immunotherapy vs placebo at year 3. Subcutaneous immunotherapy was included as a positive control. The study was not powered to compare sublingual immunotherapy with subcutaneous immunotherapy. Results Among 106 randomized participants (mean age, 33.5 years; 34 women [32.1%]), 92 completed the study at 3 years. In the intent-to-treat population, mean TNSS score for the sublingual immunotherapy group was 6.36 (95% CI, 5.76 to 6.96) at pretreatment and 4.73 (95% CI, 3.97 to 5.48) at 3 years, and for the placebo group, the score was 6.06 (95% CI, 5.23 to 6.88) at pretreatment and 4.81 (95% CI, 3.97 to 5.65) at 3 years. The between-group difference (adjusted for baseline) was −0.18 (95% CI, −1.25 to 0.90; [P = .75]). Conclusions and Relevance Among patients with moderate to severe seasonal allergic rhinitis, 2 years of sublingual grass pollen immunotherapy was not significantly different from placebo in improving the nasal response to allergen challenge at 3-year follow-up.

Understanding the work done by NHS commissioning managers: an exploration of the microprocesses underlying day-to-day sensemaking in UK primary care organisations.

PURPOSE The purpose of this paper is to explore the practical daily work undertaken by middle-level managers in Primary Care Trusts (PCTs), focusing upon the micro-processes by which these managers enact sensemaking in their organisations. DESIGN/METHODOLOGY/APPROACH The research took a case study approach, undertaking detailed case studies in four PCTs in England. Data collection included shadowing managers, meeting observations and interviews. FINDINGS The research elucidated two categories of enactment behaviour exhibited by PCT managers: presence/absence; and the production of artefacts. Being "present" in or "absent" from meetings enacted sensemaking over and above any concrete contribution to the meeting made by the actors involved. This paper explores the factors affecting these processes, and describes the situations in which enactment of sense is most likely to occur. Producing artefacts such as meeting minutes or PowerPoint slides also enacted sense in the study sites in addition to the content of the artefact. The factors affecting this are explored. PRACTICAL IMPLICATIONS The study has practical implications for all managers seeking to maximise their influence in their organisations. It also provides specific evidence relevant to managers working in the new Clinical Commissioning Groups currently being formed in England. ORIGINALITY/VALUE The study expands the understanding of sensemaking in organisations in two important ways. Firstly, it moves beyond discourse to explore the ways in which behaviours can enact sense. Secondly, it explores the distinction between active and unconscious sensemaking.

Patterns and evolution of moral behaviour: moral dynamics in everyday life

ABSTRACT Recent research on moral dynamics (the processes and phenomena – collective or individual – by which moral behaviour and moral attitudes emerge, evolve, spread, erode or disappear) shows that an individual's ethical mind-set (i.e. outcome-based vs. rule-based) moderates the impact of an initial ethical or unethical act on the likelihood of behaving ethically on a subsequent occasion. More specifically, an outcome-based mind-set facilitates Moral Balancing (behaving ethically or unethically decreases the likelihood of engaging in the same type of behaviour again later), whereas a rule-based mind-set facilitates Moral Consistency (engaging in an ethical or unethical behaviour increases the likelihood of engaging in the same type of behaviour later on). The objective was to look at the evolution of moral choice across a series of scenarios, that is, to explore if these moral patterns (Balancing vs. Consistency) are maintained over time. The results of three studies showed that Moral Balancing is not maintained over time. On the other hand, Moral Consistency could be maintained over time, if the mind-set was reinforced before making a new moral judgment (but not otherwise).
Predicting and Observing El Ni�o

In October 1974 the occurrence of a weak El Ni�o event was predicted for early 1975 on the basis of the southern oscillation index. An expedition was organized to observe the event in the waters off Peru and Ecuador during two cruises in order to study its occurrence and its development with time. During the first cruise a massive transgression of warm low salinity water across the equator to 4�S was observed, as well as a depression of the thermocline along the equator and off the coast of South America, indicating the start of El Ni�o development. During the second cruise the oceanographic situation had changed and conditions were returning to normal.
Towards an Active Learning System for Company Name Disambiguation in Microblog Streams

In this paper we describe the collaborative participation of UvA & UNED at RepLab 2013. We propose an active learning approach for the filtering subtask, using features based on the detected semantics in the tweet (using Entity Linking with Wikipedia), as well as tweet-inherent features such as hashtags and usernames. The tweets manually inspected during the active learning process is at most 1% of the test data. While our baseline does not perform well, we can see that active learning does improve the results.
An Aspergillus nidulans bZIP response pathway hardwired for defensive secondary metabolism operates through aflR

The eukaryotic bZIP transcription factors are critical players in organismal response to environmental challenges. In fungi, the production of secondary metabolites (SMs) is hypothesized as one of the responses to environmental insults, e.g. attack by fungivorous insects, yet little data to support this hypothesis exists. Here we establish a mechanism of bZIP regulation of SMs through RsmA, a recently discovered YAP‐like bZIP protein. RsmA greatly increases SM production by binding to two sites in the Aspergillus nidulans AflR promoter region, a C6 transcription factor known for activating production of the carcinogenic and anti‐predation SM, sterigmatocystin. Deletion of aflR in an overexpression rsmA (OE:rsmA) background not only eliminates sterigmatocystin production but also significantly reduces asperthecin synthesis. Furthermore, the fungivore, Folsomia candida, exhibited a distinct preference for feeding on wild type rather than an OE:rsmA strain. RsmA may thus have a critical function in mediating direct chemical resistance against predation. Taken together, these results suggest RsmA represents a bZIP pathway hardwired for defensive SM production.
