BackgroundItem 9 of the Patient Health Questionnaire-9 (PHQ-9) queries about thoughts of death and self-harm, but not suicidality. Although it is sometimes used to assess suicide risk, most positive responses are not associated with suicidality. The PHQ-8, which omits Item 9, is thus increasingly used in research. We assessed equivalency of total score correlations and the diagnostic accuracy to detect major depression of the PHQ-8 and *** conducted an individual patient data meta-analysis. We fit bivariate random-effects models to assess diagnostic ***16 742 participants (2097 major depression cases) from 54 studies were included. The correlation between PHQ-8 and PHQ-9 scores was 0.996 (95% confidence interval 0.996 to 0.996). The standard cutoff score of 10 for the PHQ-9 maximized sensitivity + specificity for the PHQ-8 among studies that used a semi-structured diagnostic interview reference standard (N = 27). At cutoff 10, the PHQ-8 was less sensitive by 0.02 (−0.06 to 0.00) and more specific by 0.01 (0.00 to 0.01) among those studies (N = 27), with similar results for studies that used other types of interviews (N = 27). For all 54 primary studies combined, across all cutoffs, the PHQ-8 was less sensitive than the PHQ-9 by 0.00 to 0.05 (0.03 at cutoff 10), and specificity was within 0.01 for all cutoffs (0.00 to 0.01).ConclusionsPHQ-8 and PHQ-9 total scores were similar. Sensitivity may be minimally reduced with the PHQ-8, but specificity is similar.

Thermomechanical Behavior Modeling of a Cr-Ni-Mo-Mn-N Austenitic Stainless Steel

The analytical approach and the thermomechanical behavior of a Cr-Ni-Mo-Mn-N austenitic stainless steel were characterized based on the parameters of work hardening (h), dynamic recovery (r) and dynamic recrystallization (n, t_0.5), considering constitutive equations (σ, ε) and deformation conditions expressed according to the Zener-Hollomon parameter (Z). The results indicated that the curves were affected by the deformation conditions and that the stress levels increased with Z under high work hardening rates. The σ_c/σ_p ratio was relatively high in the first part of the curves, indicating that softening was promoted by intense dynamic recovery (DRV). This was corroborated by the high values of r and average stacking fault energy, γ_s_fe = 66.86 mJ/m², which facilitated the thermally activated mechanisms, increasing the effectiveness of DRV and delaying the onset of dynamic recrystallization (DRX). The second part of the curves indicates that there was a delay in the kinetics of dynamic softening, with a higher value of t_0.5 and lower values of the Avrami exponent (n) due to the competing DRV-DRX mechanisms, and steady state stress (σ_ss) was achieved under higher rates of deformation.

This paper shows an analysis of the interaction of the electromagnetic field generated by a tablet with three different models of human heads: a homogeneous model Specific Anthropomorphic Mannequin (SAM) and two heterogeneous models: an adult man and a child. The assessing dosimetric parameters used are the Specific Absorption Rate (SAR) computed by SEMCAD X. The distance between the tablet and the head models varies from 50 mm to 200 mm. The SAR decreases with the distance. The higher SAR values were obtained for SAM while the smaller for the adult. All the results are below the safety recommendations from the International Commission Non-Ionizing Radiation Protection (ICNIRP) and the federal Communications Committee (FCC). © 2015 IEEE.

In this work, the joint photocatalytical and bactericidal potential, under UV radiation, of titania and silver nano powders dispersed in PMMA and deposited on porous ceramic substrates (40 and 80 ppi) by dip- and spray-coating, were investigated in low power consumption water purification reactors, using the Escherichia coli (E. coli) as reference pathogen. The results show the effect of different reactor morphologies (porosity, permeability, mechanical strength) on the bactericidal efficiency.

A compact electromagnetic multi-resonator is presented in this paper using a new technique for chipless RFID tag data encoding. Employing Archimedean spirals, the information is applied into the spectral signature shifting resonant frequencies in several positions. The multi-resonator tag proposed operates in microwave band (between 3.0-7.0GHz) and has a coding data capacity of up to 100 decimal numbers for two resonant frequencies. The simulated and measured results show a good concordance and a great perspective to use in low-cost RFID chipless tag applications. © 2015 IEEE.

This paper shows the building of an embedded Asterisk platform as a key technique for providing Information technology classes with an extra laboratorial environment for learning Voice over Internet Protocol. Besides building the platform, the students are asked to mount a functional telephony system with it that meets the criteria of low cost, low building complexity and high adaptability to convergent networks. The Raspberry PI version B was the board used to provide portability for the students to work outside the laboratory environment. Asterisk was presented as a useful tool on which the students could create a flexible system that could be easily deployed on convergent networks. This work was developed in the Telephony subject for the Electrical engineering and the Telecommunications Systems undergraduate courses from the federal Institute of Education, science and technology of Paraíba - IFPB, and presented good results in the students' learning achievements.

In this paper the resonant behavior of frequency selective surfaces, FSS, using matryoshka geometry is analyzed considering polarizations x and y. The basics of the FSS using matryoshka geometry are described for usual and open cases, including an expression to estimate the first resonant frequency. Initially, the FSS with two concentric square rings is considered and its resonant behavior analyzed. Then, the resonant behavior of FSS with two rings matryoshka geometry is examined. The analysis is based on the electric current distribution obtained using the commercial software ANSYS-Designer. With a better understanding of the resonance nature in matryoshka geometry the design parameters can be better adjusted and desired frequency responses properly achieved. © 2015 IEEE.

The improvement on the development of porous ceramic materials has leaded to new technologies in thermal insulation, for example, composite materials for better performance of pressure vessels in rocket engines. Within this context, the present work aims to evaluate the ability of a refractory ceramic base alumina/zirconia through the processes of co-precipitation and replica method in an organic fiber template. The green body was burnt-out and sintered at 1200-1600°C to obtain the continuous porous ceramic fibers. In the FEG-SEM analysis, an interconnected porous structure with small grains was observed. The crystalline phases were determined by X-ray diffraction and compared to micro-Raman results regarding the crystalline structure confirms that there present in the material zirconia is composed of more than one phase. Porosity was calculated through a mercury porosimeter as 77.9%, and the Laser Flash method gave a thermal conductivity value of 1.61 K W.m−1 .K−1 for the Al2 O3-ZrO2 fibers. © 2015 Trans Tech Publications Ltd, Switzerland.
