Objective: To describe the feelings and symptoms of people in mental distress who lives with comorbidities between the use of alcohol and other drugs and severe and persistent mental disorder. Methodology: descriptive and qualitative study conducted in six rehab for substance abuse and a Psychosocial Care Center. The data has been collected via individual interview depth and application of therapeutic communication with 31 patients. The interviews were fully transcribed and raisins for the content analysis process, thematic modality. Results: The results were made up of units of perceptions of situations before the falling ill, its articulated beginning with motivation and drug use, as well as symptoms and concomitant feelings the disorder substance use and/or mental disorder. Final remarks: The relationship of drug use with the mental disorder at sometimes does not make clear, but it is exists, as evidenced in our study by speech of the interviewees, to the associate the use and abuse of drugs in the attempt to alleviate or deal with unpleasant affective states such as boredom, depression, anxiety and loneliness.
Maintaining Force Control Despite Changes in Emotional Context Engages Dorsomedial Prefrontal and Premotor Cortex

Viewing emotional as compared with neutral images results in an increase in force production. An emotion-driven increase in force production has been associated with increased brain activity in ventrolateral prefrontal cortex and primary motor cortex (M1). In many instances, however, force production must be held constant despite changes in emotional state and the neural circuits underlying this form of control are not well understood. To address this issue, we designed a task in which subjects viewed pleasant, unpleasant, and neutral images during a force production task. We measured brain activity using functional magnetic resonance imaging and examined functional connectivity between emotion and motor circuits. Despite similar force performance across conditions, increased brain activity was evidenced in dorsomedial prefrontal cortex (dmPFC) and left ventral premotor cortex (PMv) when force was produced during emotional as compared with neutral conditions. Connectivity analyses extended these findings by demonstrating a task-dependent functional circuit between dmPFC and ventral and dorsal portions of premotor cortex. Our findings show that when force production has to be consistent despite changes in emotional context, a functional circuit between dmPFC and PMv and dorsal premotor cortex is engaged.

The Coupled Photothermal Reaction and Transport in a Laser Additive Metal Nanolayer Simultaneous Synthesis and Pattering for Flexible Electronics

The Laser Direct Synthesis and Patterning (LDSP) technology has advantages in terms of processing time and cost compared to nanomaterials-based laser additive microfabrication processes. In LDSP, a scanning laser on the substrate surface induces chemical reactions in the reactive liquid solution and selectively deposits target material in a preselected pattern on the substrate. In this study, we experimentally investigated the effect of the processing parameters and type and concentration of the additive solvent on the properties and growth rate of the resulting metal film fabricated by this LDSP technology. It was shown that reactive metal ion solutions with substantial viscosity yield metal films with superior physical properties. A numerical analysis was also carried out the first time to investigate the coupled opto-thermo-fluidic transport phenomena and the effects on the metal film growth rate. To complete the simulation, the optical properties of the LDSP deposited metal film with a variety of thicknesses were measured. The characteristics of the temperature field and the thermally induced flow associated with the moving heat source are discussed. It was shown that the processing temperature range of the LDSP is from 330 to 390 K. A semi-empirical model for estimating the metal film growth rate using this process was developed based on these results. From the experimental and numerical results, it is seen that, owing to the increased reflectivity of the silver film as its thickness increases, the growth rate decreases gradually from about 40 nm at initial to 10 nm per laser scan after ten scans. This self-controlling effect of LDSP process controls the thickness and improves the uniformity of the fabricated metal film. The growth rate and resulting thickness of the metal film can also be regulated by adjustment of the processing parameters, and thus can be utilized for controllable additive nano/microfabrication.
Layered Performance Modelling of a CORBA-based Distributed Application Design

With advances in distributed platforms, distributed application systems on heterogeneous platforms have become a reality. These systems are complex, with software and hardware components that are distributed geographically, sometimes globally, yet they combine to provide a single processing model. Deciding how to distribute software and hardware resources for these systems is a major challenge and is influenced by factors such as security, reliability, manageability, and performance. In this paper, we focus on the performance behaviour of a design for a CORBA-based Distributed Network Management Application. Once the design is established and the system’s development begins, performance problems resulting from a poor design can be difficult and expensive to fix. We built both simulation and analytic models, and used the models to help recognize such problems early. We discuss the proposed system architecture, simulation and analytic models for the application, and extensions to the analytic models needed to support features present in the design.
Genome-wide evidence for an essential role of the human Staf/ZNF143 transcription factor in bidirectional transcription

In the human genome, ∼10% of the genes are arranged head to head so that their transcription start sites reside within <1 kbp on opposite strands. In this configuration, a bidirectional promoter generally drives expression of the two genes. How bidirectional expression is performed from these particular promoters constitutes a puzzling question. Here, by a combination of in silico and biochemical approaches, we demonstrate that hStaf/ZNF143 is involved in controlling expression from a subset of divergent gene pairs. The binding sites for hStaf/ZNF143 (SBS) are overrepresented in bidirectional versus unidirectional promoters. Chromatin immunoprecipitation assays with a significant set of bidirectional promoters containing putative SBS revealed that 93% of them are associated with hStaf/ZNF143. Expression of dual reporter genes directed by bidirectional promoters are dependent on the SBS integrity and requires hStaf/ZNF143. Furthermore, in some cases, functional SBS are located in bidirectional promoters of gene pairs encoding a noncoding RNA and a protein gene. Remarkably, hStaf/ZNF143 per se exhibits an inherently bidirectional transcription activity, and together our data provide the demonstration that hStaf/ZNF143 is indeed a transcription factor controlling the expression of divergent protein–protein and protein–non-coding RNA gene pairs.
Skin-Test Screening and Tuberculosis Transmission among the Homeless

We describe the implementation of a mandatory tuberculosis (TB) screening program that uses symptom screening and tuberculin skin testing in homeless shelters. We used the results of DNA fingerprinting of Mycobacterium tuberculosis isolates to evaluate the effect of the program on TB incidence and transmission. After the program was implemented, the proportion of cases among homeless persons detected by screening activities increased, and the estimated TB incidence decreased from 510 to 121 cases per 100,000 population per year. Recent transmission, defined by DNA fingerprinting analysis as clustered patterns occurring within 2 years, decreased from 49% to 14% (p=0.03). Our results suggest that the shelter-based screening program decreased the incidence of TB by decreasing its transmission among the homeless.
The Effect of Red on Avoidance Behavior in Achievement Contexts

This research tests whether the perception of red in an achievement context evokes avoidance behavior without conscious awareness and also examines the context specificity of the hypothesized red effect. In Experiment 1, participants were briefly shown red or green on the cover of an analogies test that they would ostensibly take (an achievement context) or rate on likability of (a nonachievement context) in an adjacent lab. Those shown red, relative to those shown green, knocked fewer times on the door of the adjacent lab in the achievement context; no red—green difference in knocking was observed in the nonachievement context. In Experiment 2, participants were briefly shown red, green, or gray on the cover of an IQ test that they would ostensibly take. Those shown red moved their body away from the test cover to a greater degree than did those shown green or gray. This research contributes to incipient work on color psychology and to the more established literature on the automatic link between evaluation and behavior.
A Review of Nonfamilial Intergenerational Programs on Changing Age Stereotypes and Well-Being in East Asia

ABSTRACT This paper examines whether nonfamilial intergeneration programs reduce age stereotyping and increase the well-being of both youth and older adults in five East Asian communities. We used the systematic review method and screened 2,261 abstracts, selecting 14 publications for full review. Studies reported positive attitudinal changes among young and old participants. The intergeneration programs generally covered one of two themes: art activities or cultural heritage. Three best practices that can enhance intervention effectiveness were pre-intervention training, maintaining the intensity of the intervention on a weekly base, and pair-wise matching between the two stakeholders. More studies are recommended to test intergenerational programs with randomized designs and a wider age range of young participants. Culturally specific intergenerational contact theory is also in need of development, particularly “status concern” between the young and old generation.
Estimating Regime-Switching Taylor Rules with Trend Inflation

This paper estimates regime-switching monetary policy rules featuring trend inflation using post-WWII US data. We find evidence in favour of regime shifts and time-variation of the inflation target. We also find a drop in the inflation gap persistence when entering the Great Moderation sample. Estimated Taylor rule parameters and regimes are robust across different monetary policy models. We propose an `internal consistency' test to discriminate among our estimated rules. Such a test relies upon a feedback mechanism running from the monetary policy stance to the inflation gap. Our results support the stochastic autoregressive process as the most consistent model for trend inflation, above all when conditioning to the post-1985 subsample.

Human keratinocyte growth factor effects in a porcine model of epidermal wound healing

Keratinocyte growth factor (KGF) is a member of the fibroblast growth factor (FGF) family (hence the alternative designation FGF-7). It is produced by stromal cells, but acts as a mitogen for epithelial cells. We examined the effects of topically applied KGF on healing of wounds in a porcine model. In partial-thickness wounds, KGF stimulated the rate of reepithelialization (p < 0.0002), associated with a thickening of the epidermis (p < 0.0001). Epidermis from KGF-treated full-thickness wound sites was significantly thicker (0.31 +/- 0.22 mm) compared with mirror image control sites (0.18 +/- 0.12 mm) (p < 0.0001). Moreover, the majority (77%) of KGF-treated wounds exhibited epidermis with a deep rete ridge pattern as compared with control sites. These effects were observed as early as 14 d and persisted for at least 4 wk. KGF treatment also increased the number of serrated basal cells associated with increased deposition of collagen fibers in the superficial dermis adjacent to the acanthotic epidermis. Electron microscopy revealed better developed hemidesmosomes associated with thicker bundles of tonofilaments in the serrated cells. The pattern of epidermal thickening observed in KGF-treated wounds resembled psoriasis. Psoriasis is a disease associated with epidermal thickening, parakeratosis as well as hyperproliferation that extends beyond the basal layer. In striking contrast to psoriasis, KGF-treated wounds exhibited normal orthokeratotic maturation, and proliferation was localized to the basal cells. Our present findings have significant implications concerning the role of KGF as a paracrine modulator of epidermal proliferation and differentiation.
Cancer at the Dinner Table: Experiences of Psilocybin-Assisted Psychotherapy for the Treatment of Cancer-Related Distress

Recent randomized controlled trials of psilocybin-assisted psychotherapy for patients with cancer suggest that this treatment results in large-magnitude reductions in anxiety and depression as well as improvements in attitudes toward disease progression and death, quality of life, and spirituality. To better understand these findings, we sought to identify psychological mechanisms of action using qualitative methods to study patient experiences in psilocybin-assisted psychotherapy. Semistructured interviews were conducted with 13 adult participants with clinically elevated anxiety associated with a cancer diagnosis who received a single dose of psilocybin under close clinical supervision. Transcribed interviews were analyzed using interpretative phenomenological analysis, which resulted in 10 themes, focused specifically on cancer, death and dying, and healing narratives. Participants spoke to the anxiety and trauma related to cancer, and perceived lack of available emotional support. Participants described the immersive and distressing effects of the psilocybin session, which led to reconciliations with death, an acknowledgment of cancer’s place in life, and emotional uncoupling from cancer. Participants made spiritual or religious interpretations of their experience, and the psilocybin therapy helped facilitate a felt reconnection to life, a reclaiming of presence, and greater confidence in the face of cancer recurrence. Implications for theory and clinical treatment are discussed.
Global optimization of Optimal Power Flow using a branch & bound algorithm

We propose two algorithms for the solution of the Optimal Power Flow (OPF) problem to global optimality. The algorithms are based on the spatial branch and bound framework with lower bounds on the optimal objective function value calculated by solving either the Lagrangian dual or the semidefinite programming (SDP) relaxation. We show that this approach can solve to global optimality the general form of the OPF problem including: generation power bounds, apparent and real power line limits, voltage limits and thermal loss limits. The approach makes no assumption on the topology or resistive connectivity of the network. This work also removes some of the restrictive assumptions of the SDP approaches [1], [2], [3], [4], [5]. We present the performance of the algorithms on a number of standard IEEE systems, which are known to have a zero duality gap. We also make parameter perturbations to the test cases that result in solutions that fail to satisfy the SDP rank condition and have a non-zero duality gap. The proposed branch and bound algorithms are able to solve these cases to global optimality.
A Selective Review of the Simulation of the Defect Structure of Dislocation-Free Silicon Single Crystals

A brief review of the current state of theoretical description of the formation of the defect structure of dislocation-free silicon single crystals was carried out. Emphasis was placed on a new diffusion model of formation grown-in microdefects. It is shown that the diffusion model can describe the high-temperature precipitation of impurities during the cooling of the crystal after growth. Shown that the model of the dynamics of point defects can be considered as component part of the diffusion model for formation grown-in microdefects. PACS: 61.72. Bb; 61.72. Ji; 61.72. Yx.
The one-dimensional Fourier representation and large angular scale foreground contamination in the three-year Wilkinson Microwave Anisotropy Probe data

We employ the one-dimensional Fourier representation (1DFR) to analyse the three-year WMAP de-biased internal linear combination (DILC) map and its possible contamination with galactic foregrounds. The 1DFR is a representation of the spherical harmonic coefficients for each ℓ mode using an inverse Fourier transform into one-dimensional curves. On the basis of the a priori assumption that the cosmic microwave background signal should be statistically independent of, and consequently have no significant correlation with, any foregrounds, we cross correlate the 1DFR curves of 2 ≤ ℓ ≤ 10 modes, which are claimed by the WMAP team to be free of contamination and suitable for whole-sky analysis. We find that eight out of the nine modes are negatively cross correlated with the foreground maps, an event which has a probability of only 9/512 ≃ 0.0176 for uncorrelated signals. Furthermore, the local extrema of the 1DFR curves between the DILC and those of the foregrounds for ℓ = 2 and 6 are correlated with significance level below 0.04. We also discuss the minimum variance optimization method and use the properties of the measured cross correlation to estimate the possible level of contamination present in the DILC map.
Ozone hole and Southern Hemisphere climate change

Climate change in the Southern Hemisphere (SH) has been robustly documented in the last several years. It has altered the atmospheric circulation in a surprising number of ways: a rising global tropopause, a poleward intensification of the westerly jet, a poleward shift in storm tracks, a poleward expansion of the Hadley cell, and many others. While these changes have been extensively related with anthropogenic warming resulting from the increase in greenhouse gases, their potential link to stratospheric cooling resulting from ozone depletion has only recently been examined and a comprehensive picture is still lacking. Examining model output from the coupled climate models participating in the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment (AR4), and grouping them depending on the stratospheric ozone forcing used, we here show that stratospheric ozone affects the entire atmospheric circulation in the SH, from the polar regions to the subtropics, and from the stratosphere to the surface. Furthermore, model projections suggest that the anticipated ozone recovery, resulting from the implementation of the Montreal Protocol, will likely decelerate future climate change resulting from increased greenhouse gases, although it might accelerate surface warming over Antarctica.
Classroom Instructional Characteristics in Attention Deficit Hyperactivity Disorder: Comparison of Pure and Mixed Subgroups

Recent proposed amendments to the federal special education law and proposed definitional changes in the seriously emotionally disturbed category suggest that attention deficit hyperactivity disorder may become an increasingly important diagnostic entity within the field of behavioral disorders. To examine the potential impact on special education programs, 30 boys with pure hyperactivity (i.e., no other associated diagnoses) and 41 boys with mixed hyperactivity (i.e., hyperactivity with conduct or oppositional defiant disorders) were examined as to their IQ and academic functioning. Academic function was measured both on psychoeducational tests and on curriculum-based probes. Findings suggest a great deal of heterogeneity on all measures along with some decrement in academic performance if conduct or oppositional disorder were also present. Decrements tended to be statistically significant, however, on only two of several measures given. Reading comprehension results are of particular interest as are the small percentage of subjects who potentially qualify as learning disabled. Implications for academic expectations and special education eligibility are discussed.
Distributed source coding of video with non-stationary side-information

In distributed video coding, the complexity of the video encoder is reduced at the cost of a more complex video decoder. Using the principles of Slepian andWolf, video compression is then carried out using channel coding principles, under the assumption that the video decoder can temporally predict side-information that is correlated with the source video frames. In recent work on distributed video coding the application of turbo codes has been studied. Turbo codes perform well in typical (tele-)communications settings. However, in distributed video coding the dependency channel between source and side-information is inherently non-stationary, for instance due to occluded regions in the video frames. In this paper, we study the modeling of the virtual dependency channel, as well as the consequences of incorrect model assumptions on the turbo decoding process. We observe a strong dependency of the performance of the distributed video decoder on the model of the dependency channel.
