Which patients are seen by an occupational psychiatry service?

BACKGROUND Common mental disorders are the leading cause of sickness absence but are frequently misdiagnosed and undertreated. It is against this background that a specialist occupational psychiatry clinic was established at a London teaching hospital. AIMS To explore the nature of patients and complaints seen in the clinic and investigate whether this form of service provision reached patients who may have otherwise been missed in the gap between primary and secondary care. METHODS We reviewed the case notes of 51 consecutive new clinic assessments using a data extraction form, gathering information on socio-demographic and occupational details; the nature, duration and severity of symptoms [as assessed by Health of the Nation Outcome Scale (HoNOS)]; diagnosis; prior treatment and the outcome of the clinic appointment. RESULTS Only half of those seen in the new clinic were currently on sick leave. The most common diagnosis was depression with most having symptoms lasting longer than 9 months. Sixty-five per cent had a medium or high HoNOS rating. Although 75% had received treatment from their general practitioner, the majority remained functionally impaired, and only 31% had been seen in secondary care. CONCLUSIONS Specialist occupational psychiatry clinics do not replicate the work already being done by standard mental health services. Patients referred to a new specialist clinic within an occupational health department had chronic, debilitating psychiatric illnesses, which in many cases had failed to respond adequately to primary care treatment and were at risk of falling into the gap between primary and secondary services.
Cross-cultural adaptation and reliability testing of Polish adaptation of the European Heart Failure Self-care Behavior Scale (EHFScBS)

Background Development of simple instruments for determination of self-care levels in heart failure (HF) patients is a subject of ongoing research. One such instrument, gaining growing popularity worldwide, is the European Heart Failure Self-care Behavior Scale (EHFScBS). The aim of this study was to adapt and to test reliability of the Polish version of EHFScBS. Method A standard guideline was used for translation and cultural adaptation of the English version of EHFScBS into Polish. The study included 100 Polish HF patients aged between 24 and 91 years, among them 67 men and 33 women. Cronbach’s alpha was used for analysis of the internal consistency of EHFScBS. Results Mean total self-care score in the study group was 34.2±8.1 points. Good or satisfactory level of self-care were documented in four out of 12 analyzed EHFScBS domains. Cronbach’s alpha for the entire questionnaire was 0.64. The value of Cronbach’s alpha after deletion of specific items ranged from 0.55 to 0.65. Conclusion Polish HF patients present significant deficits of self-care, which are to a large extent associated with inefficacy of the public health care system. Apart from cultural characteristics, the socioeconomic context of the target population should be considered during language adaptation of EHFScBS, as well as during interpretation of data obtained with this instrument. A number of self-care–related behaviors may be optimized as a result of appropriate educational activities, also those offered by nursing personnel.
Congestion balancing using re­ECN

The emergence of a metric for congestion exposure at the network layer has the potential to significantly impact networking without disrupting the current Internet architecture. Re-ECN (1), a protocol for adding accountability for congestion, has been proposed as a means of aligning incentives between economic stakeholders, securing networks against denial of service and enforcing fairness between users. Our work builds on the information contained in re-ECN packet markings to balance congestion, rather than load, across domains according to expected upstream congestion.
A cross-impact simulation forecast of the data processing industry

This paper describes the application of the USC Center of Future Research's Cross-Impact Model to the simulation of the evolution of an emerging industry. The Data Processing Industry (DP) and its emerging Network and Decentralized Systems sub-industries are used to illustrate the application of the model. This application of the USC cross-impact forecasting model to the simulation of the evolution of an emerging industry and its component parts will constitute its first micro-economic application.
Construction and Characterization of Three Wheat Bacterial Artificial Chromosome Libraries

We have constructed three bacterial artificial chromosome (BAC) libraries of wheat cultivar Triticum aestivum Wangshuibai, germplasms T. monococcum TA2026 and TA2033. A total of 1,233,792,170,880 and 263,040 clones were picked and arrayed in 384-well plates. On the basis of genome sizes of 16.8 Gb for hexaploid wheat and 5.6 Gb for diploid wheat, the three libraries represented 9.05-, 2.60-, and 3.71-fold coverage of the haploid genomes, respectively. An improved descending pooling system for BAC libraries screening was established. This improved strategy can save 80% of the time and 68% of polymerase chain reaction (PCR) with the same successful rate as the universal 6D pooling strategy.
Image stablization for 2D barcode in handheld devices

With the ubiquitous of cellular phones, mobile applications with 2D barcodes have drawn a lot of attentions in recent years. However, the previous works for extracting 2D barcodes from an image do not consider the distortion resulted from camera shake. Moreover, the previous works for extracting 2D barcodes from an image do not take a complex background into account. In this paper, therefore, we propose an efficient and effective algorithm to extract 2D barcode from a complex background in a camera-shaken image. Compared with previous approaches, our algorithm outperforms in not only smaller running time but also higher accuracy of the barcode recognition.
Multiscale geometric texture analysis of ultrasound images of carotid atherosclerosis

In this paper two wavelet extension methods, the ridgelet (DRT) and the fast discrete curvelet (FDCT) transforms, were used in an attempt to characterize carotid atherosclerotic plaque from B-mode ultrasound and discriminate between symptomatic and asymptomatic cases. The mean and standard deviation of the detail subimages produced for each decomposition scheme were used as texture features. Feature selection included ranking the features in terms of their divergence values. The selected features were subsequently input to a classifier using support vector machines. Both transforms produced an 82.5% overall classification performance (75% and 85% for systole and 90% and 80% for diastole for DRT and FDCT, respectively). Those preliminary results in a somewhat limited sample population showed that, in terms of classification accuracy of ultrasound images of the carotid artery, ridgelet and curvelet transforms are equivalent. The faster and most sensitive FDCT algorithm might be a reasonable choice.
An unbiased deep search for small-area molecular structures

Context. Small-area molecular structures (SAMS) resembling clumpuscules proposed as candidates for baryonic dark matter, have been detected in an area where the shielding is too low for them to survive for a long time. Aims. I present the results of an unbiased deep search for molecular clumpuscules to study the frequency of occurence of such structures. Methods. The area surrounding these structures has been surveyed using the FCRAO 14m telescope in the CO (1 → 0) transition. The field covered is 20 � by 20 � . The resulting rms of the data is only 0.04 K in a 0.127 km s −1 wide channel. Additionally, high-angular resolution observations of the 13 CO and C 18 O( J = 1 → 0) transitions were obtained with the IRAM Plateau-de-Bure Interferometer. Results. 3 new SAMS have been detected. The structures have very low intensities which makes it impossible to detect them in large scale CO surveys conducted to map the molecular gas of the Milky Way. Their radial velocity is similar to that of the surrounding HI gas. The clouds follow the same size-linewidth relation as found for giant molecular clouds or Galactic cirrus clouds. The observations clearly show that most of the large linewidths observed at low angular resolution are caused by a large velocity difference between the clumps seen at highest angular resolution. The non-detection of the structures in the high-angular resolution observations of the 13 CO and C 18 O( J = 1 → 0) transitions shows that the 12 CO (J = 1 → 0) transition must have a low optical depth. At an adopted distance of 100 pc the structures have masses of only Jupiter mass or below. Conclusions. The new observations show that SAMS might be an abundant phenomenon in the interstellar medium but not recognized as such due to their small size. If they are made of ordinary interstellar matter with solar metallicity they likely contribute only little to the total interstellar mass.
A Preliminary Study on Portable Interceptor Mechanism to SOAP

Web Services have become increasingly popular in distributed applications, and the SOAP technology is currently the most widely used Web Service. Recently, middleware researchers have applied the interception approach to problems in various domains. Instead of providing a portable interceptor like that used in the CORBA protocol, SOAP 1.2 provides an intermediary mechanism, which has to solve the backward compatible issue to be used as an interceptor. In this paper, we evaluate the interception requirements for CA, CF, FT, and LB. Our findings suggest that the run-time administration features of the current CORBA Portable Interceptor are not appropriate for some application domains. This motivates us to develop a new Portable Interceptor Mechanism (PIM) for SOAP so that the protocol meets the interception requirements of all Web Services. The proposed PIM includes portable interceptor management in the SOAP engine and portable interceptor interface definitions.
An exploration of the influence of school context, ethos and culture on teacher career-stage professional learning

Abstract School ethos and culture, and their influence on teacher career-stage learning, are integral yet often overlooked components of school-based professional development planning. An in-depth study was conducted over two years within and across three independent schools in Sydney, Australia utilising a collegial methodology centred on principles of action research and focused on continuous school improvement. It revealed how specific school contexts have a substantial and differential impact on teacher learning across all career stages from neophyte to principal. Each school’s ethos and culture were seen to produce a distinctive teacher learning culture that subsequently influenced whole-school planning for, and participation in, teacher professional development. Teacher growth, well-being and job satisfaction were integrally related to ethos and culture and further influenced by the specific characteristics of the career stage of the teachers and school executive involved. The study gave further insights as to how the nature of teacher learning changes according to career stage. It was evident from the study that, for teachers, the school that they are in has a sizable impact on the nature of their professional learning and how they develop differentially at each stage of their career path trajectories.
Automatic Semantic Role Annotation for Portuguese

This paper describes an automatic annotation system for semantic roles, implemented as an independent add­on module for syntactically parsed text. The formalism uses hand­written Constraint Grammar (CG) rules to map and disambiguate 40 different semantic roles. As a proof­of­concept, an evaluation on treebank data was performed, where the system achieved an average F­score of 88.6.
A Systemic Mock Circulation for In-Vitro Testing of a Pneumatically Operated Left Ventricular Assist Device

Abstract This work presents the development of a systemic mock circulation loop designed for testing of an axial flow, pneumatically operated left ventricular assist device (LVAD). A simulation of the heart proximal systemic circulation has been implemented that resembles the environment in which the LVAD will be operating, from where a hydraulic system, with several reconsiderations, has been constructed. An alternative method for measurement of the pulsatile aortic flow is suggested. A significant match between the simulated and measured system responses is demonstrated which substantially simplifies the search for parameter sets that determine the hemodynamic behavior of the system. Due to a high degree of flexibility and a wide range of hemodynamic states that can be simulated, the presented mock circulation is suitable for in-vitro experiments with the LVAD.
Fertility in Norwegian testicular cancer patients

The intention was to explore the relationship between fertility and testicular cancer, including the possibly treatment-induced changes over time in the post-diagnostic fertility. Data are from the Norwegian Cancer Registry, The Norwegian Population Register and the Population Censuses. By estimating Poisson regression models, birth rates among testicular cancer patients were compared with those of other men who had the same age, parity and duration since previous birth. Poisson regression models were also estimated to check whether men's parity has an effect on the cancer incidence. Fertility rates among testicular cancer patients born after 1935 and treated before 1991 decreased by roughly 30% when compared with the normal population. The introduction of cisplatin chemotherapy and of nerve-sparing RPLND in the 1980s seems to have enabled more patients with non-seminoma to father a child after treatment, or at least shortened the time to conception. Moreover, the risk of being diagnosed with seminoma is reduced with increasing parity. This suggests that the relatively low fertility after diagnosis may be partly due to the continuing inherent influence of a sub- or infecundity that also had a bearing on the development of the disease. © 2000 Cancer Research Campaign
Davis' Convexity Theorem and Extremal Ellipsoids

We give a variety of uniqueness results for minimal ellipsoids circumscribing and maximal ellipsoids inscribed into a convex body. Uniqueness follows from a convexity or concavity criterion on the func- tion used to measure the size of the ellipsoid. Simple examples with non-unique minimal or maximal ellipsoids conclude this article. MSC 2000: 52A27, 52A20
Why Are Radio Galaxies Prolific Producers of Type Ia Supernovae?

An analysis of SN Ia events in early-type galaxies from the database of Cappellaro and coworkers provides conclusive evidence that the rate of SNe Ia in radio-loud galaxies is about 4 times higher than the rate measured in radio-quiet galaxies, i.e., SN Ia rate(radio-loud galaxies) = 0.43 h SNu as compared to SN Ia rate(radio-quiet galaxies) = 0.11 h SNu. The actual value of the enhancement is likely to be in the range ~2-7 (P ~ 10-4). This finding puts on robust empirical grounds the results obtained by Della Valle & Panagia on the basis of a smaller sample of SNe. We analyze the possible causes of this result and conclude that the enhancement of the SN Ia explosion rate in radio-loud galaxies has the same origin as their being strong radio sources, but there is no causal link between the two phenomena. We argue that repeated episodes of interaction and/or mergers of early-type galaxies with dwarf companions, on timescales of about 1 Gyr, are responsible for both inducing strong radio activity observed in ~14% of early-type galaxies and supplying an adequate number of SN Ia progenitors to the stellar population of elliptical galaxies.
Intrinsic Defect in T Cell Production of Interleukin (IL)-13 in the Absence of Both IL-5 and Eotaxin Precludes the Development of Eosinophilia and Airways Hyperreactivity in Experimental Asthma

Interleukin (IL)-5 and IL-13 are thought to play key roles in the pathogenesis of asthma. Although both cytokines use eotaxin to regulate eosinophilia, IL-13 is thought to operate a separate pathway to IL-5 to induce airways hyperreactivity (AHR) in the allergic lung. However, identification of the key pathway(s) used by IL-5 and IL-13 in the disease process is confounded by the failure of anti–IL-5 or anti–IL-13 treatments to completely inhibit the accumulation of eosinophils in lung tissue. By using mice deficient in both IL-5 and eotaxin (IL-5/eotaxin−/−) we have abolished tissue eosinophilia and the induction of AHR in the allergic lung. Notably, in mice deficient in IL-5/eotaxin the ability of CD4+ T helper cell (Th)2 lymphocytes to produce IL-13, a critical regulator of airways smooth muscle constriction and obstruction, was significantly impaired. Moreover, the transfer of eosinophils to IL-5/eotaxin−/− mice overcame the intrinsic defect in T cell IL-13 production. Thus, factors produced by eosinophils may either directly or indirectly modulate the production of IL-13 during Th2 cell development. Our data show that IL-5 and eotaxin intrinsically modulate IL-13 production from Th2 cells and that these signaling systems are not necessarily independent effector pathways and may also be integrated to regulate aspects of allergic disease.
On complex LLL algorithm for integer forcing linear receivers

Integer-forcing (IF) linear receiver has been recently introduced for multiple-input multiple-output (MIMO) fading channels. The receiver has to compute an integer linear combination of the symbols as a part of the decoding process. In particular, the integer coefficients have to be chosen based on the channel realizations, and the choice of such coefficients is known to determine the receiver performance. The original known solution of finding these integers was based on exhaustive search. A practical algorithm based on HKZ and Minkowski lattice reduction algorithms was also proposed recently. In this paper, we propose a low-complexity method to obtain the integer coefficients for the IF receiver. For the 2 × 2 MIMO channel, we study the effectiveness of the proposed method in terms of the ergodic rate. We also compare the bit error rate (BER) of our approach with that of other linear receivers, and show that the suggested algorithm outperforms the minimum mean square estimator (MMSE) and zero-forcing (ZF) linear receivers, but trades-off error performance for complexity in comparison with the IF receiver based on exhaustive search or on HKZ and Minkowski lattice reduction algorithms.
Supervised learning sets benchmark for robust spike rate inference from calcium imaging signals

A fundamental challenge in calcium imaging has been to infer spike rates of neurons from the measured noisy calcium fluorescence traces. We systematically evaluate a range of spike inference algorithms on a large benchmark dataset (>100.000 spikes) recorded from varying neural tissue (V1 and retina) using different calcium indicators (OGB-1 and GCaMP6). We introduce a new algorithm based on supervised learning in flexible probabilistic models and show that it outperforms all previously published techniques. Importantly, it even performs better than other algorithms when applied to entirely new datasets for which no simultaneously recorded data is available. Future data acquired in new experimental conditions can easily be used to further improve its spike prediction accuracy and generalization performance. Finally, we show that comparing algorithms on artificial data is not informative about performance on real data, suggesting that benchmark datasets such as the one we provide may greatly facilitate future algorithmic developments.
Alternative face models for 3D face registration

3D has become an important modality for face biometrics. The accuracy of a 3D face recognition system depends on a correct registration that aligns the facial surfaces and makes a comparison possible. The best results obtained so far use a one-to-all registration approach, which means each new facial surface is registered to all faces in the gallery, at a great computational cost. We explore the approach of registering the new facial surface to an average face model (AFM), which automatically establishes correspondence to the pre-registered gallery faces. Going one step further, we propose that using a couple of well-selected AFMs can trade-off computation time with accuracy. Drawing on cognitive justifications, we propose to employ category-specific alternative average face models for registration, which is shown to increase the accuracy of the subsequent recognition. We inspect thin-plate spline (TPS) and iterative closest point (ICP) based registration schemes under realistic assumptions on manual or automatic landmark detection prior to registration. We evaluate several approaches for the coarse initialization of ICP. We propose a new algorithm for constructing an AFM, and show that it works better than a recent approach. Finally, we perform simulations with multiple AFMs that correspond to different clusters in the face shape space and compare these with gender and morphology based groupings. We report our results on the FRGC 3D face database.
Iterative Evaluation of a Participatory Designed Online Course

We present an iterative hybrid formative evaluation methodology incorporated in a Participatory Design process for an online multimedia course in Modern Greek. Our hybrid evaluation incorporates student surveys, log file analysis, solicitation of student feedback, and monitoring student discussions. The evaluation process is ongoing, and its results are incorporated in the design of the course. The hybrid methodology allows us to capture user feedback that we would not have been able to record with surveys composed of static sets of questions.
New Efficient and Practical v-Fairness (t, n) Multi-Secret Sharing Schemes

Secret sharing plays an important role in protecting confidential information among all participants. A fairness secret sharing scheme assures that a dishonest participant cannot get any advantages over the honest ones in the process of secret reconstruction. Though there are many secret sharing schemes available in the literature, most of them do not satisfy the requirement of fairness. In this paper, we focus on v-fairness (t, n) multi-secret sharing schemes which are (t, n) threshold multi-secret sharing schemes with the feature of fairness even if there are v<t/2 dishonest participants. We show security weaknesses in an existing v-fairness (t, n) multi-secret sharing scheme, and then present two new v-fairness (t, n) multi-secret sharing schemes. Our new schemes are not only secure, but also remove the need for private channels.
