Detection and facial recognition for investigation

This special problem issue is intended to help in the detection and face recognition in order to arrest suspects for investigative by using techniques and tricks “Eigen Face” and pairing with “SIFT” (Scale invariant Feature Transform). If it found to be suspect, it will hit the frame surrounding the face of the suspect and the suspect's case number. Then, it will pair face to face in a database system that work properly and accurately detecting faces arrest by the accused. From a face detection and recognition test by the accused in various environments, it is found that Straight face, Side face at a 45-degrees angle and 90-degrees angle have detection accuracy 90, 80 and 64 percent respectively. So, this device can detect faces arrest by the accused precisely and improve investigative actions. Therefore, this research conclude that it can display photos, faces, and notification data, the number of suspects, according to the arrest warrant, and can lead to practical use.
Brazilian Journal of Microbiology (2012):

Bio-ethanol production from cane molasses (diluted to 15 % sugar w/v) was studied using the bacterium, Zymomonas mobilis MTCC 92 entrapped in luffa (Luffa cylindrica L.) sponge discs and Ca-alginate gel beads as the immobilizing matrices. At the end of 96 h fermentation, the final ethanol concentrations were 58.7 ± 0.09 and 59.1 ± 0.08 g/l molasses with luffa and Ca-alginate entrapped Z. mobilis cells, respectively exhibiting 83.25 ± 0.03 and 84.6 ± 0.02 % sugar conversion. There was no statistical significant difference (Fischer’s LSD) in sugar utilization (t = 0.254, p<0.801) and ethanol production (t =-0.663, p<0.513) between the two immobilization matrices used. Further, the immobilized cells in both the matrices were physiologically active for three more cycles of operation with less than 15 % decrease in ethanol yield in the 4 cycle, which was due to some leakage of cells. In conclusion, luffa sponge was found to be equally good as Ca-alginate as a carrier material for bacterial (Z. mobilis) cell immobilization for ethanol production. Further, it has added advantages such as it is cheap, non-corrosive and has no environmental hazard.
THE CORPORATE SOCIAL RESPONSIBILITY-FINANCIAL PERFORMANCE MISSING LINK: COMPLEMENTARITY BETWEEN ENVIRONMENTAL, SOCIAL AND BUSINESS BEHAVIOUR?

This article analyses the complementarity between various dimensions of corporate social responsibility (CSR) and financial performance. We hypothesise that the absence of consensus in the empirical literature on the CSR-financial performance relationship may be explained by the existence of synergies (complementarity) and trade-offs (substitutability) between the different CSR components. We investigate such relationships using a sample of 595 firms from 15 European countries over the 2002-2007 period. The results suggest some kind of trade-offs between CSR components. Some CSR combinations appear as relative complements, human resources and business behaviour towards customers and suppliers, suggesting mutual benefits and less conflicts between those stakeholders. Conversely, environment and business behaviour towards customers and suppliers appear as relative substitutes, suggesting more conflict or over-investment between such types of stakeholders.

The Relationship Between Transfer Student Status, Student Engagement, and High-Impact Practice Participation

Objective: Based on the growing number of transfer students in higher education and the concern that transfer students are not as engaged as their peers, specifically in participation in high-impact practices (HIPs), this research asks, “Is there a significant direct or indirect relationship between transfer status, student engagement, and HIP participation? ” Method: The current study employed a general latent variable model to explore the relationship between community college transfer student status, student engagement, and participation in HIPs. Using data from the 2014 administration of the National Survey of Student Engagement, 22,994 senior student responses were examined to measure the association between transfer status (students who transferred from a 2-year to 4-year institution compared with nontransfer students), student engagement (collaborative learning, student–faculty interaction, and supportive campus environment), and HIP participation (learning community, service-learning, research with a faculty member, internship, study abroad, and culminating senior experience). Results: Although each of the student engagement indicators significantly mediated HIP participation for transfer students, only the effect for student–faculty interaction was nontrivial. Contributions: The results from this study indicate the importance of faculty in advocating for and supporting transfer students, while presenting questions about the degree to which these students may need additional institutional support to recognize HIPs in a 4-year context. Implications for enhancing student–faculty interaction among transfer students, as a means to increase HIP participation, are discussed.
Event-related functional magnetic resonance imaging in Parkinson's disease before and after levodopa.

Event-related functional MRI (fMRI) was used to study blood oxygen level dependent cortical signal changes associated with volitional limb movements off and on levodopa in Parkinson's disease. Eight patients with early stage akinetic Parkinson's disease and eight healthy volunteers underwent three functional imaging runs (high speed echo planar imaging with 600 scans/run) while performing paced single joystick movements in a freely chosen direction every 7-15 s. The non-magnetic joystick was linked to a monitoring system for on-line registration of performance parameters along with timing of the pacing tones and fMRI-scan acquisition parameters. This allowed correlation of movement onset, i.e. event-onset, to scanning time. We repeated the scanning procedure in the Parkinson's disease patients when akinesia improved 30 min after oral levodopa. Compared with the control group, patients both off and on levodopa showed movement-related impaired activation in the rostral supplementary motor area and increased activation in primary motor cortex (M1) and the lateral premotor cortex bilaterally. Levodopa led to a relative normalization of the impaired activation in the mesial premotor cortex and decreased signal levels in M1, lateral premotor and superior parietal cortex. We conclude that levodopa improves impaired motor initiation in the supplementary motor area and decreases hyperfunction of lateral premotor and M1 associated with Parkinson's disease during simple volitional movements.
Basement membrane components in healing rabbit corneal epithelial wounds: immunofluorescence and ultrastructural studies

The nature of the substrate that supports epithelial migration in vivo is of interest, particularly with respect to mechanisms of wound healing. Immunofluorescence and electron microscopy were used to search for common substrate components in prototype rabbit corneal wounds: epithelial scrape wounds, in which the corneal or conjunctival epithelium migrated over the denuded lamina densa of the corneal basement membrane (CBM), and superficial keratectomy, in which the corneal epithelium migrated over a bare stroma without CBM. The corneal epithelium moved rapidly over the CBM or stroma to cover the defect within 2-3 d, whereas the conjunctival epithelium required 1-2 wk. In all wounds, fibronectin and fibrin/fibrinogen were deposited onto the bare surface within 8 h after wounding and persisted under the migrating epithelium until migration was complete. Bullous pemphigoid antigen (BPA), a normal component of the CBM, was removed with the epithelium upon scrape wounding and reappeared in the CBM after migration was completed. In contrast, the conjunctival epithelium had a continuous subepithelial band of BPA out to the migrating tip. Laminin, also a normal component of the CBM, was not removed in the scrape wounds, indicating that the region of least resistance to shear stress was between the BPA and laminin layers. Laminin was removed by superficial keratectomy and was not detectable under the leading edge of the migrating cells. Laminin and BPA were restored in the CBM by 2-4 wk. Type IV collagen could not be detected in normal CBM, but was conspicuously present in conjunctival basement membrane and in blood vessels. Focal bands of type IV collagen did appear in the newly synthesized CBM 2-4 wk after keratectomy. These results argue that BPA, laminin, and type IV collagen are not essential for the migration of corneal epithelium during wound healing and support the hypothesis that fibronectin and fibrin/fibrinogen are the common, perhaps the essential, components of the provisional matrix that serves as a substrate until the permanent attachment components are regenerated.
Fast signature-based color-spatial image retrieval

This paper presents a novel method of retrieving images based on color-spatial information. For each image, its color-spatial information is compactly captured by a set of color signatures and an image signature. During the image retrieval process, the color and image signatures of the query image and those of the database images are compared to determine the set of candidate images to be retrieved. In particular our similarity measure takes into account contributions of colors that are perceptually similar and the weightage on the object colors. To speed up the retrieval process, we also propose a filtering mechanism that employs a simple similarity measure to prune away irrelevant images quickly, before computing the more complex similarity measure on potential candidate images. We implemented the proposed method and conducted an experimental study on an image database consisting of 12,000 images. Our results show the retrieval effectiveness and efficiency of the proposed color-spatial approach.
Individual differences in effects of secondary cognitive activity during driving on temperature at the nose tip

Several researches have pointed out that the temperature at the nose tip is possibly effective for evaluating driver mental condition. In order to establish methods for driver monitoring, whether a method should be adapted to each person or not is an important question. This paper investigates individual differences in effects of performing a cognitively distracting subtask during driving on the temperature at the nose tip. Using a fixed-base driving simulator, we collected the data for five persons. The results show that it is commonly observed the decrease of the temperature when a participant performs the secondary task as the previous researches have pointed out. The difference in the slope of the decrease was small among the participants. However, the amount of the decrease differed from participant to participant. The timings of starting the decrease and the recovery were also person-dependent.
No fear, no panic: probing negation as a means for emotion regulation.

This electroencephalographic study investigated if negating one's emotion results in paradoxical effects or leads to effective emotional downregulation. Healthy participants were asked to downregulate their emotions to happy and fearful faces by using negated emotional cue words (e.g., no fun, no fear). Cue words were congruent with the emotion depicted in the face and presented prior to each face. Stimuli were presented in blocks of happy and fearful faces. Blocks of passive stimulus viewing served as control condition. Active regulation reduced amplitudes of early event-related brain potentials (early posterior negativity, but not N170) and the late positive potential for fearful faces. A fronto-central negativity peaking at about 250 ms after target face onset showed larger amplitude modulations during downregulation of fearful and happy faces. Behaviorally, negating was more associated with reappraisal than with suppression. Our results suggest that in an emotional context, negation processing could be quite effective for emotional downregulation but that its effects depend on the type of the negated emotion (pleasant vs unpleasant). Results are discussed in the context of dual process models of cognition and emotion regulation.
Moving object extraction in PTZ camera using the integration of background subtraction and local histogram processing

This paper proposes a technique of extracting moving object using a pan-tilt-zoom (PTZ) camera. The technique is based on the integration of background subtraction and local histogram processing. Background images are modeled as multiple images and their corresponding camera pose information (pan and tilt angles). To detect object in current image, first the system will determine the most matched background based on the acquired PTZ's pose information. Then the matched background is compensated with respect to current image, whereby the background subtraction is done between the two aligned images. The resultant output is then cleaned up using morphological opening operator, before local histogram processing is done and finally followed by closing operation. The results show the moving object can be successfully extracted after go through these four steps.
Single-unit analysis of postnatal olfactory learning: modified olfactory bulb output response patterns to learned attractive odors

Neonatal rats learn to approach odors associated with stimulation normally provided by their mother. The present report describes changes in olfactory bulb single-unit activity following olfactory learning in young rats. Rat pups were exposed from postnatal day 1 to 18 to either (1) peppermint-scented air while receiving tactile stimulation (Pepp- Stroked), (2) peppermint-scented air with no tactile stimulation (Pepp- Only), (3) clean air and tactile stimulation (Stroked-Only), or (4) clean air and no tactile stimulation (Naive). On day 19, single-unit activity was recorded from mitral/tufted cells in urethane- anesthetized, freely breathing pups in response to either peppermint or a novel orange odor. Mitral/tufted cell response patterns to peppermint were significantly altered in Pepp-Stroked animals compared to control pups. Peppermint exposure alone, not associated with tactile stimulation (Pepp-Only), did not affect subsequent single-cell response patterns to that odor. In addition, the modification of response patterns was specific to peppermint and was not associated with a change in respiration rate. Furthermore, Pepp-Stroked pups had a relative behavioral preference for peppermint on day 19 compared to control pups. These results demonstrate that postnatal olfactory learning selectively modifies the subsequent response patterns of olfactory bulb output cells to the attractive odor. Furthermore, these results indicate that the initial coding of an odorxy's attractive value occurs within the olfactory bulb.
Vitamin D3 influence the Th1/Th2 ratio in C57BL/6 induced model of experimental autoimmune encephalomyelitis

Objective(s): Multiple Sclerosis (MS) is known as a progressive inflammatory CNS disease. Cytokines belong to Th1 or Th2 family and inflammatory cells, play significant role in pathophysiology of MS. Thus, any treatment supposed to influence the relation between Th1 to Th2 cytokines expression. Although vitamin D has been prescribed as a therapeutic supplement of MS for a long time, it is not clear how much it may affect the Th1/Th2 ratio. To answer this question the present research was designed. Materials and Methods: Thirty C57BL/6 adult female mice were used. The animals were randomly divided into trial and control groups. Experimental Autoimmune Encephalomyelitis (EAE) modeling for MS and clinical scoring as cited by others was used. Based on scoring and step of the disease vitamin D3 prescription (5 mg/kg) started and continued for three weeks. Results: By using ELISA and RT-PCR the brain level of TNF-α, IL-10, IL-4 and IL-12 determined. Significant decrease of clinical symptoms in trial group which received vitamin D was seen comparing to control animals (P<0.05). The level of TNF-α but not IL-10 significantly decreased following vitamin D3 administration. By comparing the level of Th1 and Th2 Interleukins and counting the ratio of them we found that in treated animals the ratio was significantly less than non-treated (P=0.01). Conclusion: According to the results, vitamin D3 may be able to suppress the inflammatory ways that lead to progression of MS. Whether this ability is clinically valuable in human subjects is not clear and needs more clinical research.
Myocardial infarction increases ACE2 expression in rat and humans.

AIMS Angiotensin converting enzyme (ACE) 2 catalyses the cleavage of angiotensin (Ang) I to Ang 1-9 and of Ang II to Ang 1-7. ACE2 deficiency impairs cardiac contractility and upregulates hypoxia-induced genes, suggesting a link with myocardial ischaemia. We studied the expression of ACE2 after myocardial infarction (MI) in the rat as well as in human failing hearts. METHODS AND RESULTS Rats were killed at days 1, 3, and 28 after MI, or treated for 4 weeks with the ACE inhibitor ramipril (1 mg/kg). Cardiac gene and protein expression of ACE and ACE2 were assessed by quantitative real-time reverse transcriptase-polymerase chain reaction and immunohistochemistry/activity assays/in vitro autoradiography, respectively. Both ACE (P = 0.022) and ACE2 (P = 0.015) mRNA increased in the border/infarct area compared with the viable area at day 3 after MI. By day 28, increases in ACE (P = 0.005) and ACE2 (P = 0.006) mRNA were also seen in the viable myocardium of MI rats compared with myocardium of control rats. ACE2 protein localized to macrophages, vascular endothelium, smooth muscle, and myocytes. Ramipril attenuated cardiac hypertrophy and inhibited cardiac ACE. In contrast, ramipril had no effect on cardiac ACE2 mRNA, which remained elevated in all areas of the MI rat heart. Immunoreactivity of both ACE and ACE2 increased in failing human hearts. CONCLUSION The increase in ACE2 after MI suggests that it plays an important role in the negative modulation of the renin angiotensin system in the generation and degradation of angiotensin peptides after cardiac injury.
Relaxation of a dewetting contact line. Part 1. A full-scale hydrodynamic calculation

The relaxation of a dewetting contact line is investigated theoretically in the so-called ‘Landau–Levich’ geometry in which a vertical solid plate is withdrawn from a bath of partially wetting liquid. The study is performed in the framework of lubrication theory, in which the hydrodynamics is resolved at all length scales (from molecular to macroscopic). We investigate the bifurcation diagram for unperturbed contact lines, which turns out to be more complex than expected from simplified ‘quasi-static’ theories based upon an apparent contact angle. Linear stability analysis reveals that below the critical capillary number of entrainment, Cac, the contact line is linearly stable at all wavenumbers. Away from the critical point, the dispersion relation has an asymptotic behaviour σ∝|q| and compares well to a quasi-static approach. Approaching Cac, however, a different mechanism takes over and the dispersion evolves from ∼|q| to the more common ∼q2. These findings imply that contact lines cannot be described using a universal relation between speed and apparent contact angle, but viscous effects have to be treated explicitly.
Comparing Multi-label Classification with Reinforcement Learning for Summarisation of Time-series Data

We present a novel approach for automatic report generation from time-series data, in the context of student feedback generation. Our proposed methodology treats content selection as a multi-label (ML) classification problem, which takes as input time-series data and outputs a set of templates, while capturing the dependencies between selected templates. We show that this method generates output closer to the feedback that lecturers actually generated, achieving 3.5% higher accuracy and 15% higher F-score than multiple simple classifiers that keep a history of selected templates. Furthermore, we compare a ML classifier with a Reinforcement Learning (RL) approach in simulation and using ratings from real student users. We show that the different methods have different benefits, with ML being more accurate for predicting what was seen in the training data, whereas RL is more exploratory and slightly preferred by the students.
Moral Judgments and Motivation: Making Sense of Mixed Intuitions

© 2016 by Centre for Ethics, KU Leuven. All rights reserved. doi: 10.2143/EP.23. 2.3157181 AbstrAct. The present article suggests an approach to the debate between motivational judgment internalism and motivational judgment externalism that can accommodate the fact that most individuals seem to hold a mix of internalist and externalist intuitions. Drawing on psychologist Augusto Blasi’s ‘self model’, I contend that the notion of identity-based motivation can provide a straightforward story about moral judgments and motivation in a way that makes sense of our mix of intuitions. Despite not appearing to fit neatly under either internalism or externalism, the resulting view seems able to account for many of the longstanding concerns of the debate.
The G11.11–0.12 Infrared-dark Cloud: Anomalous Dust and a Nonmagnetic Isothermal Model

The G11.11-0.12 infrared-dark cloud has a filamentary appearance, both in absorption against the diffuse 8 μm Galactic background and in emission from cold dust at 850 μm. A detailed comparison of the dust properties at these two wavelengths reveals that standard models for the diffuse interstellar dust in the Galaxy are not consistent with the observations. The ratio of absorption coefficients within the cloud is κ8/κ850 ≤ 1010, which is well below that expected for the diffuse interstellar medium where κ8/κ850 ~ 1700. This may be due to the formation of ice mantles on the dust and grain coagulation, both of which are expected within dense regions of molecular clouds. The 850 μm emission probes the underlying radial structure of the filament. The profile is well represented by a marginally resolved central region and a steeply falling envelope, with Σ(r) ∝ r-α, where α ≥ 3, indicating that G11.11-0.12 is the first observed filament with a profile similar to that of a nonmagnetic isothermal cylinder.
