Writing Comprehensive Behavioral Consultation Reports: Critical Elements

The accountability movement in psychology has resulted in practitioners increasingly using evidence-based interventions and treatment modalities to treat client problems. Behavioral consultation is one framework that practitioners can utilize in providing empirically supported services. In order to demonstrate the use of effective, evidence-based psychological practices, however, practitioners must carefully consider how they document their services and their outcomes. This article examines factors that practitioners must consider when writing reports on behavioral consultation cases. In addition, this article reviews 18 critical components that should be included in comprehensive behavioral consultation reports.
DC/DC converter 3D assembly for autonomous sensor nodes

This paper reports on the design and the manufacturing of an integrated DCDC converter, which respects the specificity of sensor node network: compactness, high efficiency in acquisition and transmission modes, and compatibility with miniature Lithium batteries. A novel integrated circuit (ASIC) has been designed and manufactured to provide regulated Voltage to the sensor node from miniaturized, thin film Lithium batteries. Then, a 3D integration technique has been used to integrate this ASIC in a 3 layers stack with high efficiency passives components, mixing the wafer level technologies from two different research institutions. Electrical results have demonstrated the feasibility of this integrated system and experiments have shown significant improvements in the case of oscillations in regulated voltage. However, stability of this output voltage toward the input voltage has still to be improved.
Apps, Apps, and More Apps: Motivations and User Behaviours

This paper explores the reasons millions of people use stand-alone, task-oriented software programs designed for use on mobile devices, commonly known as "apps. " This study uses a survey with a probability sample of 576 app users. Consistent with the uses and gratifications approach, respondents were asked about their attitudes, interests, and opinions regarding apps. Theses measures were reduced to five factors. Then, regression analyses considered the factors as well as app use statistics and demographics to predict app use. The motivations of entertainment, convenience, and instrumentality are consistent with previously studied gratifications of the Internet and the mobile phone. However, the constant availability gratification for apps is unique because they provide quick access to information anytime and anywhere. Regression analysis showed these motivations predicted patterns of app use.
Maestro2: Experimental Evaluation of Communication Performance Improvement Techniques in the Link Layer

Cluster computers became the vehicle of choice to build high performance computing environments. To fully exploit the computing power of these environments, technologies for high performance networks and protocols have to be applied, since the communication patterns of parallel applications running on clusters demand low latency and high throughput. Our previous work identifies the main drawbacks of conventional network technologies, and proposed some techniques to solve them within a new network solution called Maestro. This paper describes not only the architecture and the evaluation platform of the Maestro2, but also the technologies introduced for enhancing the performance of the original Maestro framework. Novel techniques are proposed at the link layer and at the switching level, and its design and implementation in the Maestro2 is discussed: continuous network burst and out-of-order switching. Moreover, a specialized communication library has been developed to take full advantage of these new techniques for implementing high speed cluster networks based on the Maestro2 environment. Experimental results clearly show that the new proposed techniques provide significant improvements, both in terms of latency and throughput, which are essential to efficient cluster computing.
Uncertainty Quantification for Electromagnetic Systems Using ASGC and DGTD Method

In this paper, an adaptive hierarchical sparse grid collocation (ASGC) method combined with the discontinuous Galerkin time-domain method is leveraged to quantify the impacts of random parameters on the electromagnetics systems. The ASGC method approximates the stochastic observables of interest using interpolation functions over a set of collocation points determined by the Smolyak's algorithm integrated with an adaptive strategy. Instead of resorting to a full-tensor product sense, the Smolyak's algorithm constructs the collocation points in a hierarchical scheme with the interpolation level. Enhanced by an adaptive strategy, the Smolyak's algorithm will sample more points along important dimensions with sharp variations or discontinuities, resulting in a nonuniform sampling scheme. To flexibly handle different stochastic systems, either piecewise linear or Lagrange polynomial basis functions are applied. With these strategies, the number of collocation points is significantly reduced. The statistical knowledge of stochastic observables including the expected value, variance, probability density function, and cumulative distribution function are presented. The accuracy and robustness of the algorithm are demonstrated by various examples.
ETA, Mixed ETA/ETB Receptor Antagonists, and Protein Kinase C Inhibitor Prevent Acute Hypoxic Pulmonary Vasoconstriction: Influence of Potassium Channels

The aims of this study were to investigate the effects of a selective ETA (BQ-123), a selective ETB (BQ-788), and a specific mixed ETA/ETB receptor antagonist (bosentan) on the pulmonary vasoconstriction induced by hypoxia in the isolated perfused rat lung, and the role of nitric oxide, adenosine triphosphate–sensitive (KATP), large conductance Ca+-activated (BKCa) and 4-aminopyridine–sensitive voltage-gated K+ channels (KV) in the relaxant effects of the selective ETA receptor antagonist BQ-123 and a protein kinase C inhibitor, bisindolylmaleimide I. K+ channels were inhibited by glibenclamide, charybdotoxin, and 4-aminopyridine and nitric oxide synthase by l-NG-nitroarginine methyl ester (l-NAME). Hypoxic ventilation produced a significant pressure response (+57%, p < 0.001). BQ-123, bosentan, and bisindolylmaleimide I induced a concentration-dependent decrease of the hypoxic pressure response (p < 0.001), whereas BQ-788 did not exhibit any inhibitory effect against hypoxic pressure response. Glibenclamide, charybdotoxin, and 4-aminopyridine partially opposed the inhibitory effects elicited by BQ-123 (p < 0.05), but l-NAME did not modify these effects. The effects of bisindolylmaleimide I on hypoxic pressure response were unaffected by glibenclamide, charybdotoxin, or 4-aminopyridine. The authors conclude that (a) ETA receptors and protein kinase C are involved in the modulation of hypoxic pulmonary vasoconstriction; and (b) the ETA antagonist BQ-123 opposes hypoxic pulmonary vasoconstriction through KATP, Kv, and BKCa channels, differing in this from the protein kinase C inhibitor bisindolylmaleimide I. These results suggest that BQ-123 operates through a mechanism independent of bisindolylmaleimide I–inhibited protein kinase C isoforms.
Intersexuality in a Charolais heifer

naive but at the same time have the same grazing pattern and this is often difficult to achieve. The persistent activity of a drug can also be determined in field trials. In this case, the appearance of worm eggs or larvae in the faeces of treated animals grazing continuously on contaminated pastures can be evaluated. Faecal samples are collected regularly and, after faecal culture, the genera of nematodes present are identified. For interpretation of the duration of persistence, the prepatent period must be taken into account. If parasite naive animals are used, the difference in time of appearance of nematode eggs or larvae in the faeces can be taken as an approximation of the duration of persistent activity. In the case of cattle that are already shedding nematode eggs or larvae at the time of treatment, it is
A High-Resolution Frequency Estimation Method for Three-Phase Induction Machine Fault Detection

Fault detection in alternating-current electrical machines that is based on frequency analysis of stator current has been the interest of many researchers. Several frequency estimation techniques have been developed and are used to help the induction machine fault detection and diagnosis. This paper presents a technique to improve the fault detection technique by using the classical multiple signal classification (MUSIC) method. This method is a powerful tool that extracts meaningful frequencies from the signal, and it has been widely used in different areas, which include electrical machines. In the proposed application, the fault sensitive frequencies have to be found in the stator current signature. They are numerous in a given frequency range, and they are affected by the signal-to-noise ratio. Then, the MUSIC method takes a long computation time to find many frequencies by increasing the dimension of the autocorrelation matrix. To solve this problem, an algorithm that is based on zooming in a specific frequency range is proposed with MUSIC in order to improve the performances of frequency extraction. Moreover, the method is integrated as a part of MUSIC to estimate the frequency signal dimension order based on classification of autocorrelation matrix eigenvalues. The proposed algorithm has been applied to detect a rotor broken bar fault in a three-phase squirrel-cage induction machine under different loads and in steady-state condition.
Immunization with Treponema pallidum endoflagella alters the course of experimental rabbit syphilis

Rabbits were immunized over a 32-week period with a total of 450 micrograms of purified Treponema pallidum endoflagella. As measured by enzyme-linked immunosorbent assay, sera from immunized rabbits had antiendoflagellar antibody titers that were fivefold greater than titers of sera from infected immune rabbits and patients with secondary disease. Sera from all immunized animals possessed complement-dependent treponemicidal activity as measured by in vitro immobilization. Immunized animals challenged with virulent T. pallidum were not protected from symptomatic infection but showed an altered course of lesion development.
Structure, Mechanism, and Regulation of Mammalian Adenylyl Cyclase*

The discovery of 39,59-cyclic adenosine monophosphate (cAMP) in the late 1950s by Sutherland and co-workers was the pivotal event that led to our current paradigm of hormone signaling through second messengers. Despite the subsequent discovery of many other second messengers, cAMP has never left center stage. The adenylyl cyclases are the family of enzymes that synthesize cAMP (1–5). Breakthroughs in determining the first structures of the mammalian adenylyl cyclase catalytic core (6, 7) provide a new context for understanding the action of many regulators, both physiological and pharmacological: free metal ions, P-site inhibitors, forskolin, G-proteins, Ca/calmodulin, and protein phosphorylation. Understanding the catalytic mechanism of an enzyme is a prerequisite to understanding its regulation. Here I will describe the essentials of catalysis and then consider how these elements are controlled by each of the major regulators.
Streptococcus pneumoniae Isolates Expressing a Capsule with Epitopes of Both Serotypes 6A and 6B

ABSTRACT Four Streptococcus pneumoniae isolates expressing both 6A and 6B capsular serotypes were detected by a multiplex immunoassay. The sequence of WciP, a GT2-family glycosyltransferase, indicates that point mutation has compromised linkage specificity, allowing two alternative oligosaccharides to be synthesized. This finding highlights that mutation as well as recombination can mediate serotype change.
International Conference on Intelligent Robots and Systems Yokohama , Japan Juiy 2630 , 1993 FORCE-CONTROLLED ASSEMBLY WITH A TWO-ARM ROBOT : HOW AND WHERE TO PERFORM IT WITHIN THE WORKSPACE

It is now well known that the use of two-arm robots is very interesting to perform complex tasks that "handicapped" single-arm robots cannot perform [I]. Among these new tasks, the manipulation of a single object has often been studied and many control solutions have been formulated. These solutions are based upon pure position control schemes [ 2 ] , masterhlave force control schemes [3], or hybrid position/force control schemes [4, 51. However, some other important applications have not been very much analyzed, yet mentioned by some researchers in the field. For instance, it appears that assembIy tasks using two cooperating arms can be needed in some cases. As a matter of fact, when robots work in a structured environment such as a factory, it is often possible to perform automated assemblies by using a single manipulator and an accessory device aimed at supporting one of the objects; this device can be a simple work-bench, a vice, or more sophisticated any mechanism. With this idea in mind, some people suggested to use a second robot as a supporting mechanism, sometimes referred to as a "left hand". The workspace of this left hand is often limited, since its role is just to compensate for small position errors of the main manipulator. To go a little bit further, one can imagine using two "regular" manipulators working in a cooperative way in order to assemble two objects "in space", that is to say with each object being held by one manipulator. Besides the advantage of getting thus a redundant
The influence of calcium supplement on body composition, weight loss and insulin resistance in obese adults receiving low calorie diet

BACKGROUND: Obesity and diabetes are the most important problems of public health. Evidence from molecular animal research and epidemiologic investigations indicate that calcium intake may have an influence on body composition, weight and insulin resistance. The objective of this study was to determine the effects of calcium supplementation on body composition, weight, insulin resistance and blood pressure in the face of calorie restriction in obese adults. METHODS: A double blind randomized placebo-controlled trial on 40 adults with Body Mass Index > 25kg/m2 was conducted. Subjects were maintained for 24 weeks on a balanced deficit diet (-500 kcal/d deficit) and randomly assigned into two groups with 1000 mg ca/d as calcium carbonate or placebo. RESULTS: There were no significant differences in variables at the 12th and 24th week between the two groups. The lean mass showed no significant increase in the calcium group at the 12th week compared to baseline and in placebo group at the 24th week compared to the 12th week. The insulin concentration showed a significant decrease in the calcium group at the 12th week compared to the baseline (p < 0.05). The diastolic blood pressure had a significant decrease at the 24th week compared to the 12th week in both groups (p = 0.013-0.009). CONCLUSIONS: Results from this study suggest that 24 weeks of supplementation with 1000 mg ca/d did not have any effect on weight, body composition, insulin resistance and blood pressure beyond what can be achieved in an energy restricted diet in obese adults.
GENDER DIFFERENCE IN PLASMA LEVELS OF INTERFERON ALPHA 2 B IN CHRONIC HEPATITIS C PATIENTS

The study was conducted to investigate the gender difference for the concentration of interferon alpha 2b in patients with chronic hepatitis C. In a Quasi – experimental study 60 patients were allocated to male and female groups, each comprising n=30. In both groups, the patients had age between 20 and 49 year. A first dose of 3 × 10 3 units of interferon alpha 2b was administered subcutaneously. The blood samples were collected at baseline (0 time), 8 h and 20 h after the administration of interferon according to a limiting sampling strategy. All samples were analyzed by ELISA to measure the plasma interferon levels. Comparison between two groups was significant where the interferon levels were higher (63.0 10.26 IU/ml ) in males as compared to females (45.63 7.73 IU/ml.) at 8 h post drug administration. Base line value of plasma interferon level was below the quantitative level while at 20 h, the plasma level of interferon in males was lower but non-significantly than in females (5.54 0.8 IU/ml vs 5.73 1.16 IU/ml ). Almost all patients (98%) reported typical mild interferon side effects (flu-like symptoms and headache).
Output power maximization of IPMSM using overmodulation region of direct torque control system

This paper proposes an interior permanent magnet synchronous motor drive system based on direct torque control of the overmodulation region of an inverter. It is important to operate in the overmodulation region to maximize the motor output power. An overmodulation pulse width modulation (PWM) drive and a square-wave drive are used for high-power operation because of the high voltage utilization of the inverter. The proposed system performs amplitude compensation for an overmodulation PWM drive, terminal voltage estimation for a square-wave drive, and selection of these drives. The effectiveness of the proposed system is experimentally demonstrated.
Use of Lanczos Tau Method to Derive Polynomial Approximate from the Addition Theorem of Slater Type Orbitals

Motivation. Multi–center integrals are certainly the building blocks of quantum chemistry packages ranging from semi–empirical to the so–called ab initio. The efficiency (accuracy and speed) of the numerical methods used for the computation of such integrals is therefore of extreme importance since millions of these need to be computed for molecules of practical interest. In this work, the Lanczos W method is applied to derive a polynomial approximate to the so–called one–center expansion of Slater Type Orbitals (STOs). The procedure is applied to the three–center nuclear attraction integrals, which are essential not only in quantum chemistry but also to model electron–molecule scattering. Method. Starting with a spherical Slater Type Orbital a differential equation governing such functions is elaborated. The application of the Lanczos W to the differential equation enables us to obtain a polynomial approximate, and more importantly the corresponding absolute error. Such an approximate is afterwards used in the master formula allowing the computation of multi–center integrals over STOs. Results. Numerical values for three–center nuclear attraction integrals are reported. Comparison with previous work is performed. Conclusions. Multi–center integrals over STOs are still a challenging problem. The case of nuclear attraction integral is among the problems that can be tackled with various approaches including the one presented in this work. However for fully functional quantum chemistry software using STOs to be efficient it is necessary to combine the best of all methods by selecting the most appropriate tool for each case.
Development of a hydrogen gas sensor based on a suspended monolithic carbon nanowire platform

We introduce a hydrogen gas sensor based on a suspended monolithic carbon nanowire structure. This structure provides selective and sensitive hydrogen sensing capability and unique advantages overcoming limitation of on-plane nanostructure based sensors. The fabrication of suspended carbon nanowire consists of simple two-step conventional microfabrication processes; photolithography and pyrolysis. The monolithic structure ensures perfect ohmic contact between the nanowire and the electrical contact pads. 20 ppm of hydrogen was successfully detected by a suspended monolithic carbon nanowire (width = 300 nm, thickness = 600 nm, distance between the nanowire and the substrate = 7.3 μm) coated wiht a 10-nm-thick palladium layer.
Stepping over obstacles: dividing attention impairs performance of old more than young adults.

BACKGROUND Tripping over an obstacle is a common cause of falls in the elderly. An earlier study of abilities to avoid stepping on suddenly appearing obstacles found that, although healthy old adults had a lower rate-of-success than young adults, the magnitude of that difference was not large. The present study inquired whether dividing attention during such a task would differentially affect young and old healthy adults. METHODS Rates-of-success were observed in 16 young and 16 old healthy adults (mean ages 24 and 72 years) in avoiding stepping on a band of light that was suddenly projected across their gait path while they walked at their comfortable gait speed. This virtual obstacle was placed at predicted next-footfall locations to give 350 or 450 msec available response times before footfall. During most of the trials the subjects were asked, in addition to trying not to step on the obstacle, simultaneously to respond vocally as quickly as possible when red lights near the end of the walkway turned on. These attention-dividing reaction time tests were of two types: synchronized, when only red lights lit at intervals synchronized with the appearance of the obstacle, and unsynchronized, when green or yellow lights lit in addition to the red lights, with lighting intervals not synchronized with the appearance of the obstacle. RESULTS When synchronized and unsynchronized reaction time tests were conducted concurrently with the obstacle avoidance tasks, mean rates-of-success in avoidance decreased significantly in both young and old adults. With available response times of 350 msec, mean success rates decreased from their no-division values in the young adults by 14.7% for synchronized reaction and by 19.9% for unsynchronized reaction, attention-dividing tests. Corresponding mean decreases for the old adults were 32.0 and 35.7%. This age difference in the effects of dividing attention was significant. CONCLUSION Both young and old adults had a significantly increased risk of obstacle contact while negotiating obstacles when their attention was divided, but dividing attention degraded obstacle avoidance abilities of the old significantly more than it did in the young. Diminished abilities to respond to physical hazards present in the environment when attention is directed elsewhere may partially account for high rates of falls among the elderly.
Animal models of demyelination

In the past year, animal studies on central nervous system demyelination have focused on therapeutic strategies and the functional characterization of T-cells, cytokines, and adhesion molecules. Significant progress has been realized in the treatment of animals with experimentally induced demyelinating disease using glial cell transplants, autoantibodies, cytokines, growth factors, and by inhibiting adhesion molecules and cytokines. In this review, we summarize the important contributions made in those respective areas.
