Dynamic, dyadic, intersubjective systems: An evolving paradigm for psychoanalysis.

Dynamic systems theory is a source of powerful new metaphors for psychoanalysis. Phenomena such as conflict, transference, resistance, and the unconscious itself are grasped from this perspective as dynamically emergent properties of self-organizing, nonlinear, dyadic, intersubjective systems. The conception of development as evolving and dissolving attractor states of intersubjective systems richly illuminates the processes of pattern formation and change in psychoanalysis. Effective interpretations are seen as perturbations of the therapeutic system that permit new organizing principles to come into being.
Parallel processing flow models on desktop hardware

Numerical solution of any large, three-dimensional fluid flow problem is a computationally intensive task that typically requires supercomputer solution to achieve reasonable execution time. This paper describes an alternative approach, a technique for mapping three-dimensional fluid flow models to low-cost, desktop hardware. The approach is shown to deliver exceptional performance.
Principles of survey research: part 3: constructing a survey instrument

In this article, we discuss how to construct a questionnaire. We point out the need to use any previous research results to reduce the overheads of survey construction. We identify a number of issues to consider when selecting questions, constructing questions, deciding on the type of question and finalizing the format of the questionnaire.
Is autism curable?

Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental disorder of multifactorial origin. Today, ASD is generally not curable, although it is treatable to a varying degree to prevent worse outcomes. Some reports indicate the possibility of major improvements or even recovery in ASD. However, these studies are based on scientific shortcomings, and the lack of a clear definition of 'cure' in ASD further compromises interpretation of research findings. The development of animal models and decreasing costs of genome sequencing provide new options for treatment research and individualized medicine in ASD. This article briefly reviews several issues related to the question whether there is recovery from ASD, starting with a short overview of the presumed aetiologies.
Comparison of two different methods for urethral lengthening in female to male (metoidioplasty) surgery.

INTRODUCTION
Metoidioplasty presents one of the variants of phalloplasty in female transsexuals. Urethral lengthening is the most difficult part in this surgery and poses many challenges.


AIM
We evaluated 207 patients who underwent metoidioplasty, aiming to compare two different surgical techniques of urethral lengthening, postoperative results, and complications.


METHODS
The study encompassed a total of 207 patients, aged from 18 to 62 years, who underwent single stage metoidioplasty between September 2002 and July 2011. The procedure included lengthening and straightening of the clitoris, urethral reconstruction, and scrotoplasty with implantation of testicular prostheses. Buccal mucosa graft was used in all cases for dorsal urethral plate formation and joined with one of the two different flaps: I-longitudinal dorsal clitoral skin flap (49 patients) and II-labia minora flap (158 patients).


MAIN OUTCOME MEASUREMENT
Results were analyzed using Z-test to evaluate the statistical difference between the two approaches. Also, postoperative questionnaire was used, which included questions on functioning and esthetical appearance of participating subjects as well as overall satisfaction.


RESULTS
The median follow-up was 39 months (ranged 12-116 months). The total length of reconstructed urethra was measured during surgery in both groups. It ranged from 9.1 to 12.3 cm (median 9.5) in group I and from 9.4 to 14.2 cm (median 10.8) in group II. Voiding while standing was significantly better in group II (93%) than in group I (87.82%) (P < 0.05). Urethral fistula occurred in 16 patients in both groups (7.72%). There was statistically significant difference between the groups, with lower incidence in group II (5.69%) vs. group I (14.30%) (P < 0.05). Overall satisfaction was noted in 193 patients.


CONCLUSION
Comparison of the two methods for urethral lengthening confirmed combined buccal mucosa graft and labia minora flap as a method of choice for urethroplasty in metoidioplasty, minimizing postoperative complications.
Central versus lower body obesity distribution and the association with lower limb physical function and disability.

OBJECTIVE
To determine whether fat distribution in obese adults is significantly associated with decreased function and increased disability.


DESIGN
Cross-sectional epidemiologic analysis.


SETTING
Multicenter, community-based study.


PARTICIPANTS
Multicenter Osteoarthritis Study participants included adults ages 50-79 years at high risk of developing or already possessing knee osteoarthritis. A total of 549 men and 892 women from the Multicenter Osteoarthritis Study who had a body mass index ≥ 30 kg/m² and who underwent dual energy x-ray absorptiometry (DEXA) scans were included in these analyses. Exclusion criteria included bilateral knee replacements, cancer, or other rheumatologic disease.


METHODS
Body fat distribution was determined using baseline DEXA scan data. A ratio of abdominal fat in grams compared with lower limb fat in grams (trunk:lower limb fat ratio) was calculated. Participants were divided into quartiles of trunk:lower limb fat ratio, with highest and lowest quartiles representing central and lower body obesity, respectively. Backward elimination linear regression models stratified by gender were used to analyze statistical differences in function and disability between central and lower body obesity groups.


MAIN OUTCOME MEASURES
Lower limb physical function measures included 20-meter walk time, chair stand time, and peak knee flexion and extension strength. Disability was assessed using the Late Life Function and Disability Index.


RESULTS
Trunk:lower limb fat ratio was not significantly associated with physical function or disability in women or men (P value .167-.972). Total percent body fat (standardized β = -0.1533 and -0.1970 in men and women, respectively) was a better predictor of disability when compared with trunk:lower limb fat ratio (standardized β = 0.0309 and 0.0072).


CONCLUSIONS
Although fat distribution patterns may affect clinical outcomes in other areas, lower limb physical function and disability do not appear to be significantly influenced by the distribution of fat in obese older adults with, or at risk for, knee osteoarthritis. These data do not support differential treatment of functional limitations based on fat distribution.
Customer Satisfaction and Service Quality to Develop Trust and Positive Word of Mouth in Vocational Education

This study generally aims to analyze the influence of customer satisfaction and service quality to develop trust and positive word of mouth especially in vocational education. Students in vocational education as well as higher education are considered as an internal customer; therefore, their satisfaction and perception of service quality are potential to bridging the emergence of external satisfaction and customer loyalty. According to previous literature, internal customer satisfaction can be measured by service product, service delivery, and service environment, all of which have a significant relation with trust where trust is significantly related to word of mouth. Meanwhile, the communication, productivity and responsiveness are significant in measuring the perceptions of service quality. This study is expected to enrich managerial implication on how to measure the internal customer satisfaction and service quality toward trust and word of mouth in vocational education. Thus, the vocational education can continue to strive to provide educational service in accordance with the expectations of the customers.
Multi-plate reconstruction for severe bicondylar tibial plateau fractures of young adults

This study was to evaluate clinical outcomes and complications following multi-plate reconstruction for treating severe bicondylar tibial plateau fractures of young adults. Between September 2007 and February 2012, 26 patients with severe bicondylar tibial plateau fractures met inclusion criteria; they were treated using multi-plate technique through combined approaches. Patients received an average follow-up of 40.8 (range, 18–64) months, which included anteroposterior and lateral imaging, postoperative complications, range of motion and stability of the knee. The Rasmussen score was applied for functional and radiological evaluation. Three to five plates were used for reconstruction. No intra-operative complications occurred. Postoperative complications included bulge of hardware in four patients and superficial dehiscence in three cases in the anterolateral incision of which one developed to deep infection. There was no neurovascular damage, and no implant breakage or loosening. Hardware was removed partly or totally in 16 cases. The average Rasmussen score at final follow-up was 27.2 (range, 21–30) points for functional evaluation and 16.4 (range, 14–18) for radiology. Multi-plate reconstruction is a valid and safe method for treating severe bicondylar tibial plateau fractures of young adults.
Validation of a preparation for decision making scale.

OBJECTIVE
The Preparation for Decision Making (PrepDM) scale was developed to evaluate decision processes relating to the preparation of patients for decision making and dialoguing with their practitioners. The objective of this study was to evaluate the scale's psychometric properties.


METHODS
From July 2005 to March 2006, after viewing a decision aid prescribed during routine clinical care, patients completed a questionnaire including: demographic information, treatment intention, decisional conflict, decision aid acceptability, and the PrepDM scale.


RESULTS
Four hundred orthopaedic patients completed the questionnaire. The PrepDM scale showed significant correlation with the informed (r=-0.21, p<0.01) and support (r=-0.13, p=0.01) subscales (DCS); and discriminated significantly between patients who did and did not find the decision aid helpful (p<0.0001). Alpha coefficients for internal consistency ranged from 0.92 to 0.96. The scale is strongly unidimensional (principal components analysis) and Item Response Theory analyses demonstrated that all ten scale items function very well.


CONCLUSION
The psychometric properties of the PrepDM scale are very good.


PRACTICE IMPLICATIONS
The scale could allow more comprehensive evaluation of interventions designed to prepare patients for shared-decision making encounters regarding complex health care decisions.
Seeking the Strongest Rigid Detector

The current state of the art solutions for object detection describe each class by a set of models trained on discovered sub-classes (so called "components"), with each model itself composed of collections of interrelated parts (deformable models). These detectors build upon the now classic Histogram of Oriented Gradients+linear SVM combo. In this paper we revisit some of the core assumptions in HOG+SVM and show that by properly designing the feature pooling, feature selection, preprocessing, and training methods, it is possible to reach top quality, at least for pedestrian detections, using a single rigid component. Abstract We provide experiments for a large design space, that give insights into the design of classifiers, as well as relevant information for practitioners. Our best detector is fully feed-forward, has a single unified architecture, uses only histograms of oriented gradients and colour information in monocular static images, and improves over 23 other methods on the INRIA, ETH and Caltech-USA datasets, reducing the average miss-rate over HOG+SVM by more than 30%.

Dentigerous cyst associated with an ectopic third molar in the maxillary sinus: A case report and review of literature

Dentigerous cysts are the most common type of developmental odontogenic cysts arising from the crowns of impacted, embedded, or unerupted teeth. They constitute about 20% of all epithelium-lined cysts of the jaws. The teeth involved most often are mandibular third molar and maxillary canines. About 70% of dentigerous cysts occur in the mandible and 30% in the maxilla. Dentigerous cysts associated with ectopic teeth within the maxillary sinus are fairly rare, and only 20 cases had been reported in Medline since 1980. In the present paper, we report an additional case of dentigerous cysts associated with ectopic third molar in the right maxillary sinus. Also, pathogenesis of ectopic tooth, role of advanced imaging, differential diagnosis, and management are discussed.
Noise and Cooling in Electronics Packages

The noise produced by cooling air passing through electronics packages arises from two sources. One source is the noise of the air-moving fan of either an axial or centrifugal type. This noise may have both tonal and random components and is strongly dependent on the way that the fan is placed in the unit and on where its operation is on the fan's operating curve. Often, fans are the dominant noise sources. The flow of air produces random noise due to the turbulence generated throughout the unit. Because the turbulent airflow is also responsible for heat transfer between the components and the air stream, we can regard this part of the noise as the irreducible noise due to cooling. If fan noise were eliminated, this part of the noise would remain. There is a relation, therefore, between the irreducible noise and the cooling of the unit. But the fan noise must also be considered. The relation between total airflow related noise and cooling requirements is developed in this paper for the irreducible noise
Effects of Galla chinensis extracts on UVB-irradiated MMP-1 production in hairless mice

Galla chinensis (GAC) is a natural traditional Chinese medicine that has been widely used in folk medicine. Although GAC compounds (mainly gallic acid and methyl gallate) possess strong antiviral, antibacterial, anticancer, and antioxidant activities, there is no report regarding topical or oral administration of GAC compounds on UVB irradiation-induced photoaging in hairless mice (SKH: HR-1). In the present study, we examined cell viability, intracellular reactive oxygen species (ROS), matrix metalloproteinase-1 (MMP-1), and interleukin-6 (IL-6) in skin fibroblasts and keratinocytes induced by UVB in vitro. We also studied skin damage by measuring skin thickness, elasticity, wrinkling and levels of protein MMP-1, elastin, procollagen type I, and transforming growth factor-β1 (TGF-β1) in hairless mouse skin chronically irradiated by UVB in vivo. GAC treatment significantly prevented skin photoaging by reducing the levels of ROS, MMP-1, and IL-6 and promoting production of elastin, procollagen type I, and TGF-β1. According to the results of H&E staining and Masson’s trichrome staining, GAC reduced skin thickness and wrinkle formation while it increased skin elasticity. The effects of GAC on UVB-induced skin photoaging may be due to suppressed MMP-1 expression. These findings could be referenced for the development of new agents that target UVB-induced photoaging.
Genetic predisposition to clinical manifestations in familial adenomatous polyposis with special reference to duodenal lesions

OBJECTIVE:In familial adenomatous polyposis (FAP), genetic predisposition for duodenal adenomatosis has not been investigated precisely. The aim of this study was to investigate the correlation between adenomatous polyposis coli (APC) gene mutation and duodenal adenomatosis in FAP.METHODS:APC gene mutation was determined by means of a protein truncation test in 34 patients from 25 families with FAP. The prevalence and grade of duodenal adenomatosis were compared among the proximal mutation group (exons 1–9), the distal mutation group (exons 10–15), and the undetermined groups. The correlation between the course of duodenal adenomatosis and APC gene mutation was retrospectively investigated in 19 patients.RESULTS:The prevalence of duodenal adenomatosis was lower in the proximal mutation group (44%) than in the distal mutation (100%) and undetermined (83%) groups. In patients with positive duodenal adenomatosis, the endoscopic grade did not differ among the groups. The endoscopic grade increased in two of the four patients with the proximal mutation group (50%), in three of 10 patients with the distal mutation group (30%), and in two of five patients (40%) with the undetermined group.CONCLUSIONS:Truncating APC gene mutation proximal to exon 9 may contribute to the less frequent development of duodenal adenomatosis in FAP, but severity and progression of duodenal adenomatosis do not seem to be determined by APC gene mutation alone.
Impact of the unknown communication channel on automatic speech recognition: a review KN-29

This review article summarizes the main difficulties encountered in Automatic Speech Recognition (ASR) when the type of communication channel is not known. This problem is crucial for the development of successful applications in promising domains such as computer telephony and cars. The main technical problems encountered are due to the speaker and the task (e.g. speaking style, Lombard reflex, vocal tract geometry), the use of microphones with different characteristics, the variable quality of the support channels (e.g. telephone channels are noisy and have different characteristics), reverberation and echoes, the variable distance and direction to the microphone introduced by hands-free recognition, and the ambient noise which distorts the input speech signals. This overview characterizes and emphasizes these problems and highlights some promising directions for future research. Finally, it presents an attempt to characterize the sensitivity of a phoneme recognizer as a function of the source of channel distortion, using the TIMIT database and several of its variants (NTIMIT, CTIMIT, FFMTIMIT).
Gas Turbine Performance.

Industrial gas turbines show performance characteristics that distinctly depend on ambient and operating conditions. They are not only influenced by site elevation, ambient temperature, and relative humidity, but also by the speed of the driven equipment, the fuel, and the load conditions. Proper application of gas turbines requires consideration of these factors. This tutorial explains these characteristics based on the performance of the engine compressor, the combustor and the turbine section, and certain control strategies. It introduces fundamental concepts that help to understand the flow of energy between the components. Additionally, methods are introduced that allow the use of data for trending and comparison purposes. The impact of component degradation on individual component performance, as well as overall engine performance is discussed, together with strategies to reduce the impact of degradation.
Efficient Spatio-Temporal Data Association Using Multidimensional Assignment in Multi-Camera Multi-Target Tracking

This paper proposes a novel multi-target tracking method which solves a data association problem using images from multi-cameras. In multicameras, two combinatorial problems should be solved at the same time: spatial data association between cameras and temporal data association between frames. The spatio-temporal data association problem is a well known NP-hard problem even in a small number of cameras or frames (more than 3). Current existing methods [1, 2] simplify the spatio-temporal data association problem through assumption of simple motion model (shortest path) and 3D location estimation. However, the complexity grows exponentially with the number of cameras. In this work, the spatio-temporal data association problem is formulated as a multidimensional assignment problem (MDA). To achieve a fast, efficient, and easily implementable algorithm, we solve the MDA problem iteratively by solving a sequence of bipartite matching problems using random splitting and merging operations. Hence, the proposed algorithm can be considered as a guided random search to find the global optimum through repeated random local searches (bipartite matchings). In addition, we design a new cost function considering 3D reconstruction accuracy, motion smoothness, visibility from cameras, starting/ending at entrance and exit zone, and false positive. Our approach reconstructs 3D trajectories that represent people’s movement as 3D cylinders whose locations are estimated considering all adjacent frames (See Figure 2). The observations during 1, ...,T frames and at cameras 1, ...K form a KT-partite (hyper) graph G = (V,E) = (I11 ∪ ...∪ IKT ,E), where vertices V are partitioned into K×T different independent sets I11, ...,IKT and each hyperedge in E contains at least one vertex in each partite set. Trajectory hypotheses set T can be defined as a set of all hyperedges E. We represent each trajectory hypothesis Tn ∈ T as a matrix whose entry in the k-th row and t-th column corresponds to an observation index at the t-th frame of the k-the camera. The problem of finding a set of disjoint trajectory hypotheses with a minimum sum of costs can be formulated as the MDA problem which is equivalent to the problem of minimizing the sum of costs of hyperedges containing one element per partite set in the hypergraph G. With binary decision variables xTn ∈ {0,1} deciding whether the trajectory Tn is in the association hypothesis H, and cost function c : T→R, the objective function and disjointness constraints are given by
