Fast multi-exposure image fusion with median filter and recursive filter

This paper proposes a weighted sum based multi-exposure image fusion method which consists of two main steps: three image features composed of local contrast, brightness and color dissimilarity are first measured to estimate the weight maps refined by recursive filtering. Then, the fused image is constructed by weighted sum of source images. The main advantage of the proposed method lies in a recursive filter based weight map refinement step which is able to obtain accurate weight maps for image fusion. Another advantage is that a novel histogram equalization and median filter based motion detection method is proposed for fusing multi-exposure images in dynamic scenes which contain motion objects. Furthermore, the proposed method is quite fast and thus can be directly used for most consumer cameras. Experimental results demonstrate the superiority of the proposed method in terms of subjective and objective evaluation.
Qualitative Support for the Gradient Model of Cardiac Pacemaker Heterogeneity

In this study, we investigate the role of sinoatrial node (SAN) cellular heterogeneity in normal cardiac pacemaker function. Using detailed ionic models of electrical activity in SAN and atrial myocytes, we have formulated a number of models of SAN heterogeneity based on discrete-region (in which central and peripheral SAN type cell are separated into discrete regions), gradient and mosaic models of SAN organisation. Simulations of each of the different models were performed in one and two dimensions in the presence of both uniform and linearly increasing conductivity profiles. Simulation results suggest that the gradient model, in which cells display a smooth variation in membrane properties from the center to the periphery of the SAN, best reproduces action potential waveshapes and a site of earliest activation consistent with experimental observations in the intact SAN. We therefore propose that the gradient model of SAN heterogeneity represents the most plausible model of SAN organisation
Expectations, theory, and group processes

I am very pleased and honored to receive the 1991 Cooley-Mead Award. There are many reasons for this. First, this award is a source of pleasure that I can share with my family, particularly with my wife, Theory. Theory has been there through all the steps and stages of my work for the last 25 years, and her support and confidence in that work have been of enormous importance to me as an individual and as a sociologist. I am also pleased because I take this as an evaluation not only of my work but also of the work of a very large number of colleagues and co-workers. It is not possible for me to list the work of all those who have played active roles in expectation states research. I do want to mention, however, my three Stanford colleagues-Morris Zelditch Jr., Bernard P. Cohen, and Elizabeth G. Cohenwho have been involved in the expectation states program from its earliest phases. Finally, I am pleased by this award when I remember some of the others who have received the Cooley-Mead Award, such as Muzafer Sherif and Robert Freed Bales. These two social psychologists have strongly influenced my own work, and I am pleased to share such an honor with them. I developed my interest in sociology at a very early age-certainly long before I appreciated the diversity that exists on so many different levels in this discipline. Also very early in my career, I became interested in the study of interpersonal or group processes. I especially became intrigued with the idea of constructing theories of social behavior, particularly theories that evolved, that developed, that grew. These two interests-understanding interpersonal or group processes and constructing theories of social behavior that evolve-have been with me my
Feeling at sea: the anchor of the therapeutic space

This paper describes and discusses the creation and development of a therapeutic service set up in an inner city primary school over the period of 10 years. It explores this emotional well-being model and how it acts as an anchor for the children, staff and parents. Case examples illustrate the authors’ work in a multidisciplinary team and focuses specifically on Bion’s theory of ‘container-contained. ’ The authors underline how the therapeutic interventions need to be held in the containing vessel of the school’s robust thinking and understanding of the therapeutic process and how the therapeutic work impacts on the well-being of the children as they work on their experiences within the school and outside community.
Feature Weighting Information-Theoretic Co-Clustering for Document Clustering

This paper presents a feature weighting schema to improve the performance of Information-Theoretic Co-clustering (ITCC). The new algorithm, named as Feature Weighting Information-Theoretic Co-clustering (FWITCC), weights each feature with the mutual information shared by the features and the documents. The weighting schema makes informative features more important and noisy features less important, so that it can improve the qualities of resulted clusters. Experimental results on both synthetic data sets and 20Newsgroup data sets have demonstrated that our new approach has better clustering performance than (ITCC).
Energy-Efficient Matching for Resource Allocation in D2D Enabled Cellular Networks

Energy-efficiency (EE) is critical for device-to-device (D2D) enabled cellular networks due to limited battery capacity and severe cochannel interference. In this paper, we address the EE optimization problem by adopting a stable matching approach. The NP-hard joint resource allocation problem is formulated as a one-to-one matching problem under two-sided preferences, which vary dynamically with channel states and interference levels. A game-theoretic approach is employed to analyze the interactions and correlations among user equipments (UEs), and an iterative power allocation algorithm is developed to establish mutual preferences based on nonlinear fractional programing. We then employ the Gale–Shapley algorithm to match D2D pairs with cellular UEs, which is proved to be stable and weak Pareto optimal. We provide a theoretical analysis and description for implementation details and algorithmic complexity. We also extend the algorithm to address scalability issues in large-scale networks by developing tie-breaking and preference-deletion-based matching rules. Simulation results validate the theoretical analysis and demonstrate that significant performance gains of average EE and matching satisfactions can be achieved by the proposed algorithm.
Online reduction of fifth and seventh harmonics in single phase quasi square wave inverters

Inverters form a major part of power electronic industry. The AC output of inverter is mainly controlled by pulse width modulation (PWM) technique. The PWM approaches are accompanied by harmonics due to the switched nature of power electronic devices. There are many ways to eliminate the harmonics such as selective harmonic elimination. Selective harmonic elimination is associated with tremendous task of numerical computations in offline. The tremendous task of computing is reduced by implementing an online approach of harmonic reduction using an active filter(compensating inverter). The proposed work is implemented on a single phase quasi-square wave inverter which is considered as an abundant harmonic source. A neutral point clamped three level leg is used as main inverter as well as active filter(compensating inverter). The online computation of phase voltage harmonics is carried out on a low cost PIC 18F4550 controller. The control pulses of the active filter are generated from the phase voltage harmonics. The main inverter is connected in series with active filter(compensating inverter) in the proposed topology. Theoretical analysis of this proposed strategy is presented in this paper with simulation and experimental results. The added advantage of the proposed method is the reduction of harmonics with reduced number of devices.
Influence of temperature on the calcium sensitivity of the myofilaments of skinned ventricular muscle from the rabbit

The steady-state myofilament Ca sensitivity was determined in skinned cardiac trabeculae from the rabbit right ventricle (diameter, 0.13-0.34 mm) at 36, 29, 22, 15, 8, and 1 degree C. Muscles were stimulated to 0.5 Hz and stretched to a length at which maximum twitch tension was generated. The preparation was then skinned with 1% vol/vol Triton X- 100 in a relaxing medium (10 mM EGTA, pCa 9.0). Each preparation was exposed to a series of Ca-containing solutions (pCa 6.3-4.0) at two of the six temperatures studied (temperature was regulated to +/- 0.1 degree C). The pCa values (mean +/- SD, n = 6) corresponding to half maximal tension at 36, 29, 22, 15, 8, and 1 degree C were 5.47 +/- 0.07, 5.49 +/- 0.07, 5.34 +/- 0.05, 5.26 +/- 0.09, 4.93 +/- 0.06, and 4.73 +/- 0.04, respectively. Mean (+/- SD) maximum tension (Cmax) developed by the preparation as a percentage of that at 22 degrees C was 118 +/- 10, 108 +/- 5, 74 +/- 6, 57 +/- 7, and 29 +/- 5% at 36, 29, 15, 8, and 1 degree C, respectively. As cooling led to a shift of Ca sensitivity towards higher [Ca2+] and a reduction of Cmax, the Ca sensitivity curves over this range of temperatures do not cross over as has been described for canine Purkinje fibers (Fabiato 1985). Since tension is decreased by cooling at all levels of [Ca2+] it is unlikely that changes in myofilament Ca sensitivity play a role in the large hypothermic inotropy seen in rabbit ventricular muscle. The increase in sensitivity of the myofilaments to Ca on warming from 1 to 29 degrees C might be related to the increase in force seen on rewarming from a rapid cooling contracture in intact rabbit ventricular muscle.
Health in adolescence and subsequent receipt of social insurance benefits – The HUNT Study.

BACKGROUND Long-term illness and work incapacity in young adulthood has consequences for both the individual and for society. The purpose of the study was to investigate the association between adolescent health and receipt of long-term sickness and disability benefits for young adults in their twenties. MATERIAL AND METHOD An adolescent population of 8949 school students (aged 13-21 years) assessed their own health in the Young-HUNT1 Study (1995-1997). Health was measured by means of a questionnaire enquiring about chronic somatic illnesses, somatic symptoms, symptoms of anxiety and depression, sleep disturbance, poor concentration, self-reported health and smoking, and by measuring height and weight. Information about receipt of long-term benefits was retrieved from the FD-Trygd registry for the period 1998-2008 and defined as receipt of sickness benefit (>180 days/year), medical/vocational rehabilitation benefit and disability pension in the age group 20-29 years. We investigated the relationship between adolescent health and long-term social insurance benefits with logistic regression, adjusted for sex, age, follow-up time, mother's education and family composition. Siblings with different exposure and outcome were investigated to adjust for all familial factors shared by siblings. RESULTS Each of the health measures was associated with an increased risk of long-term benefit. For example, adolescents who reported one or more somatic illnesses or poor concentration had a 5.4 and 3.4 percentage point higher risk, respectively, of receiving long-term benefits at the age of 20-29 years than adolescents who did not report somatic illness or poor concentration. Moreover the risk increased with an increase in the number of health problems. Sibling analyses supported these associations. INTERPRETATION Health in adolescence is an indicator of increased vulnerability in the transition to the labour market. Preventing health selection during this transition should be a priority for welfare policy.
Applications of a planar separator theorem

Any n-vertex planar graph has the property that it can be divided into components of roughly equal size by removing only O(√n) vertices. This separator theorem, in combination with a divide-and-conquer strategy, leads to many new complexity results for planar graph problems. This paper describes some of these results.
Wyner-Ziv coding for video: applications to compression and error resilience

Two separate applications of Wyner-Ziv coding of motion video coding are considered. The Wyner-Ziv theorem on source coding with side information available only at the decoder suggests that an asymmetric video codec, where individual frames are encoded separately, but decoded conditionally could achieve efficiency comparable to current interframe video compression systems. First results on the Wyner-Ziv coding scheme for motion video are reported that use interframe encoding, but interframe decoding. Secondly, Wyner-Ziv coding for the transmission of compressed video over an error-prone channel is applied. This coding scheme is used to generate a supplementary bit stream, which contains a coarsely quantized representation of the transmitted video signal. Using the conventionally decoded, error-concealed video signal as side information to decode the Wyner-Ziv bits, the transmission errors in the decoded video waveform are corrected up to a certain residual distortion, significantly improving the visual quality of the decoded video.
Rational-Linear Interpolation of Texture Coordinates and Their Partial Derivatives

computer graphics, texture mapping, interpolation, texture coordinates, texture derivatives, anti-aliasing This paper describes an algorithm for calculating texture coordinates and their partial derivatives during scan conversion of planar polygons. These values are required in texture mapping for antialiasing algorithms, where a resampling filter combines texture elements (a.k.a. texels) in a weighted average. Perspective projection requires an image warp accomplished with rational-linear (a.k.a. hyperbolic) interpolation. A single division per pixel and a few addition and multiplication operations yields the texture coordinates and their partial derivatives.
Early Immune Reaction after Reduced-Intensity Cord-Blood Transplantation for Adult Patients

Background. To investigate immune reactions after reduced-intensity cord-blood transplantation (RI-CBT). Materials and Methods. We reviewed medical records of 57 adult RI-CBT recipients. Preparative regimen comprised fludarabine, total-body irradiation, and either melphalan (n=51) or busulfan (n=6). Graft-versus-host disease (GvHD) prophylaxis was cyclosporine. PostRI-CBT immune reactions were classified according to time course: pre-engraftment immune reactions (PIR), engraftment syndrome (ES), and GvHD. Results. Forty-five patients achieved engraftment at a median of day 19. PIR was characterized by high-grade fever and weight gain and developed on a median of day 9 in 35 of the 45 evaluable patients, including 3 who did not achieve engraftment. PIR subsided spontaneously in 12 patients, whereas corticosteroids were required in the other 23. ES and grade I to IV acute GvHD developed in 36 and 29 patients, respectively. GvHD could not be distinguished from preceding PIR or ES in 10 patients. Causes of the 32 nonrelapse mortalities included GvHD (n=5) and PIR (n=1). There were no significant differences in relapse and nonrelapse deaths between patients with PIR and those without it (18% vs. 5%, and 60% vs. 65%, respectively). Conclusions. Immune reactions after RI-CBT can be categorized into three distinct subtypes.
Diagnostic validity of the dementia questionnaire for Alzheimer disease.

OBJECTIVE To determine the sensitivity and specificity of postmortem dementia diagnoses based on a retrospective informant interview by comparison with criterion standard neuropathological diagnoses and the results of previous clinical examinations. SETTING Three university-based academic research centers. SUBJECTS Fifty-four deceased elderly persons with Alzheimer disease, another dementing disorder, a neurologic disease resulting in functional impairment but no dementia, or no neurologic disorder. METHODS Blinded nonclinician interviewers administered the Dementia Questionnaire (DQ) by telephone to informants, typically close relatives, who were familiar with the intellectual and functional status of the subjects before death. Two senior clinicians (LJ.T. and C.K.) rated each DQ for the presence or absence of a dementia syndrome during life and for the specific disorders causing the dementia, if present. Raters were blinded to the neuropathological findings and based their assessments only on data provided by responses to the DQ. Comparison was made with diagnoses based on neuropathological assessment. In most cases, the results of antemortem clinical examinations were also available as a check on the clinical diagnosis of the dementia syndrome. Sensitivity and specificity of the DQ diagnoses were computed, and chance-corrected agreement measures were calculated for the 2 independent DQ raters (LJ.T. and C.K.). RESULTS Compared with antemortem clinical diagnosis, the average sensitivity of the DQ for the clinical syndrome of dementia was 92.8%, the specificity was 89.5%, and the interrater agreement was 98% (kappa = 0.96). Among 7 subjects with mild dementia (Mini-Mental State Examination score > or = 24 at the last clinical examination), 5 (71%) were correctly identified using the DQ. The DQ correctly indicated the absence of dementia in 8 (80%) of 10 subjects with other neurologic disorders causing functional impairment. Compared with the neuropathological diagnoses, the DQ differentiated Alzheimer disease from other primary causes of dementia with a sensitivity of 89% and a specificity of 72%. The interrater agreement was 93.8% (kappa = 0.85). CONCLUSIONS Compared with the results of the antemortem clinical examinations, the DQ was sensitive to the presence of dementia, detected most cases of mild dementia, and discriminated dementia from other neurologic disorders causing functional impairment. Compared with the neuropathological diagnoses, the ability of the DQ to differentiate Alzheimer disease from other dementing disorders indicates that it may be useful as a research tool.
Bis is Induced by Oxidative Stress via Activation of HSF1

The Bis protein is known to be involved in a variety of cellular processes including apoptosis, migration, autophagy as well as protein quality control. Bis expression is induced in response to a number of types of stress, such as heat shock or a proteasome inhibitor via the activation of heat shock factor (HSF)1. We report herein that Bis expression is increased at the transcriptional level in HK-2 kidney tubular cells and A172 glioma cells by exposure to oxidative stress such as H2O2 treatment and oxygen-glucose deprivation, respectively. The pretreatment of HK-2 cells with N-acetyl cysteine, suppressed Bis induction. Furthermore, HSF1 silencing attenuated Bis expression that was induced by H2O2, accompaniedby increase in reactive oxygen species (ROS) accumulation. Using a series of deletion constructs of the bis gene promoter, two putative heat shock elements located in the proximal region of the bis gene promoter were found to be essential for the constitutive expression is as well as the inducible expression of Bis. Taken together, our results indicate that oxidative stress induces Bis expression at the transcriptional levels via activation of HSF1, which might confer an expansion of antioxidant capacity against pro-oxidant milieu. However, the possible role of the other cis-element in the induction of Bis remains to be determined.
A perspective into noun-before-verb bias: evidence from Turkish-Dutch speaking bilingual children

Nouns and verbs are considered as fundamental categories of lexical development from both linguistic and cognitive perspectives (Kauschke et al., 2007). From a linguistic point of view, nouns and verbs are the lexical units which categorically highlight language-general and languagespecific characteristics. Cognitive representations of nouns and verbs are also significant to consider in terms of acquisition of early lexicon. The aim of this research is, therefore, to investigate the Turkish-Flemish bilingual children’s early language period especially in terms of two syntactic categories; namely, nouns and verbs. Besides, the differences of typological characteristics between Turkish and Flemish are striking in terms of nouns and verbs. In addition to the linguistic and typological motivations, methodologically, this research aims to utilize a very fruitful data collection tool, Communicative Development Inventory (CDI), which has become an acceptable tool to use in bilingual language acquisition studies (David & Wei, 2003; Xuan & Dollaghan, 2012; De Houwer et al., 2006; Marchman & Martinez-Sussman, 2002). In line with this background, this study addresses the nature of Turkish-Flemish bilingual children’s early lexicon with respect to the noun bias phenomenon by means of data collected from 19 TurkishDanish bilingual children living in Flanders. The results of this study, of which data analysis is still in progress, were evaluated regarding the early trajectories of bilingual children’s lexical acquisition with respect to noun-before-verb pattern. Findings of this study have shown that both language-general and language-specific characteristics operate on acquisition.
Land readjustment for upgrading Indonesian kampung : a proposal

A majority of Jakarta's population resides in unregulated and densely populated settlements called kampung, with no access to utilities. The urban development policy of previous municipal governments focused strongly on modernization of the city to the neglect of the poor kampung population. The Kampung Improvement Programme, started in 1969, is considered a notable exception to this tendency. However, despite efforts to improve the conditions in kampung, the number of kampung dwellers is increasing. The governor of Jakarta aims to revitalize 350 kampung in his first term of office (by 2017). This paper investigates whether the land readjustment procedure that is applied in many countries may contribute to the realization of this ambition. The findings indicate that such is indeed the case and a pilot project is recommended.
Handicraft Women Recommendation Approach Based on User's Social Tagging Operations

Recommendation predicts which items the user might be interested in, and aims to help users finding the adequate element. Such as movies, music and commercial products, persons may be also recommended. In the case of handicraft women, we propose a recommendation approach based on extracted user's interest using his/her social tagging operations to improve business activities of the handicrafts women, the approach is applied with preliminary tests.
