European Americans were 1.27 times more likely to obtain employment than were Hispanics. Hispanics with work disincentives had lower odds of returning to work and had more unmet basic needs (eg, food, shelter, and transportation) that need to be addressed in the rehabilitation process. Job placement and on-the-job support services were found to significantly improve employment outcomes. However, on-the-job support services were more likely to be provided to European Americans than to Hispanics.

Abstract-In this paper, periodic structures are investigated in antenna design for wireless applications. These antennas were compared with CRLH miniaturization method. Three different models of patch antenna with coaxial feed on EBG ground, metamaterial substrate or EBG/AMC structure have been presented here. Also two compact dual-band antennas have been designed and fabricated based on CRLH techniques for wireless and GSM applications. The first antenna has directional pattern and operates at 1760, 2550 and 3850 MHz (three-band antenna) with gain 2.1, −3.9 and 2.5 dBi, and it is dual polarized. The size of prototype patch antenna is 20 × 20 mm 2 which is reduced about 47% in comparison to conventional patch antenna at 2.5 GHz. The second antenna is designed by the use of interdigital capacitor and spiral inductor. Dimensions of antenna are 15.5×12 mm 2 , so the size is reduced about 69% in comparison to conventional microstrip patch antennas at 1.8 GHz. The second tri-band antenna operates at 1060 MHz, 1800 MHz and 2500 MHz in which two frequencies (1.8 and 2.5 GHz) are suitable for GMS and WLAN applications. Both structures have been designed and fabricated on FR4 low cost substrate with ε r = 4.4 and thickness of 1.6 mm. All simulations are done with CST and HFSS. Equivalent circuit and experimental results are also presented and compared.

The straightforward capture of oxidized phenothiazines with phenols under aerobic conditions represents a unique cross‐dehydrogenative C−N bond‐forming reaction in terms of operational simplicity. The mechanism of this cross‐dehydrogenative N‐arylation of phenothiazines with phenols has been the object of debate, particularly regarding the order in which the substrates are oxidized and their potentially radical or cationic nature. Understanding the selective reactivity of phenols for oxidized phenothiazines is one of the key objectives of this study. The reaction mechanism is investigated in detail by utilizing electron paramagnetic resonance spectroscopy, cyclic voltammetry, radical trap experiments, kinetic isotope effects, and solvent effects. Finally, the key reaction steps are calculated by using density functional theory (DFT) and broken‐symmetry open‐shell singlet DFT methods to unravel a unique biradical mechanism for the oxidative phenothiazination of phenols.

In this article, the ultra‐wideband tapered patch antenna with fractal slots for dual notch application is presented. The antenna is printed on FR‐4 low‐cost substrate with relative permittivity of 4.4 and thickness of 1.6 mm. Total dimensions of the antenna is 45 × 44 × 1.6 mm3. In here, fractal slots was applied to represent dual notch band characteristics. The final antenna as demonstrated in this article has two rejection bands at 3 and 5 GHz and the antenna covers 2.1–12 GHz frequency band with the VSWR of less than 2. The current distribution in notch frequency and efficiency was checked for the whole frequency band and the maximum antenna gain is between 2 and 6 dBi. Finally, the experimental results are compared with the HFSS simulation ones. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1344–1348, 2014

In this article, compact antenna with high gain and circular polarization (CP) for WiMAX applications is noticed. Using metamaterials with negative permittivity and permeability improves the antenna parameters; thus, the prototype antenna is designed based on metamaterial composite right-/left-handed to achieve CP and compact size. The final antenna has directional pattern and high gain with CP at 3450MHz. The antenna gain is 8.28 dBi. The size of prototype patch antenna is 30 3 30 mm 2 . It is designed and fabricated on Taconic TLY-5, Laminate substrate with e r 5 2.2 and thickness of 1.6 mm. It is simulated by CST microwave studio and HFSS. Also, equivalent circuit and experimental results are presented and compared here.

The oculomotor system utilizes color extensively for planning saccades. Therefore, we examined how the oculomotor system actually encodes color and several factors that modulate these representations: attention-based surround suppression and inherent biases in selecting and encoding color categories. We measured saccade trajectories while human participants performed a memory-guided saccade task with color targets and distractors and examined whether oculomotor target selection processing was functionally related to the CIE (x,y) color space distances between color stimuli and whether there were hierarchical differences between color categories in the strength and speed of encoding potential saccade goals. We observed that saccade planning was modulated by the CIE (x,y) distances between stimuli thus demonstrating that color is encoded in perceptual color space by the oculomotor system. Furthermore, these representations were modulated by (1) cueing attention to a particular color thereby eliciting surround suppression in oculomotor color space and (2) inherent selection and encoding biases based on color category independent of cueing and perceptual discriminability. Since surround suppression emerges from recurrent feedback attenuation of sensory projections, observing oculomotor surround suppression suggested that oculomotor encoding of behavioral relevance results from integrating sensory and cognitive signals that are pre-attenuated based on task demands and that the oculomotor system therefore does not functionally contribute to this process. Second, although perceptual discriminability did partially account for oculomotor processing differences between color categories, we also observed preferential processing of the red color category across various behavioral metrics. This is consistent with numerous previous studies and could not be simply explained by perceptual discriminability. Since we utilized a memory-guided saccade task, this indicates that the biased processing of the red color category does not rely on sustained sensory input and must therefore involve cortical areas associated with the highest levels of visual processing involved in visual working memory.
