The significant weight loss observed with combination naltrexone-sustained release (SR) 32 mg and bupropion SR 360 (NB32) therapy is thought to be due, in part, stimulation of hypothalamic pro-opiomelanocortin (POMC) neurons, naltrexone blockade opioid receptor-mediated POMC autoinhibition, but the neurobiological mechanisms are not fully understood. We assessed changes brain reactivity food cues before after NB32 treatment. Forty women (31.1±8.1 years; body mass index: 32.5±3.9) received 4...
A novel circularly polarized (CP) dielectric resonator antenna (DRA) array is introduced. The DRA element operating at the desired frequency determined by waveguide model (DWM), and two orthogonal modes are generated to excite CP waves. 4 × 4-element then developed. fed cavity-backed slotted substrate integrated waveguide, without using extra feeding network. Experimental results show that obtains a bandwidth of 240 MHz (9.88-10.12 GHz) for reflection coefficients axial ratios (ARs) less...
Sparse linear arrays based on a novel subarrayed scheme are proposed and synthesized in this letter. The array with fixed aperture size is partitioned into several uniformly spaced subarrays while number, spacing, excitation each subarray optimized multiple constraints. Compared conventional sparse all the elements excited independently, provides excitations at port reduces control numbers remarkably. By integrating cuckoo search (CS) algorithm convex programming (CP), hybrid CS-CP method...
Wideband rotationally symmetric sparse circular arrays (RSSCAs) with multiple constraints are synthesized in this letter. First, the aperture is partitioned into several sections, and each section consists of some annular sectors (ASs). The element positions numbers these ASs optimized. Taking peak sidelobe level as fitness function, using total number array elements, size, minimum spacing between two adjacent elements to form constraints, we formulate synthesis problem a constrained...
Abstract In this article, a new differential magnetic‐field probe with high detection sensitivity for near‐field scanning is proposed. The proposed consists of U‐shaped loop as driven element, pair asymmetric inverted loops parasitic two transmission line, connected vias, shorted and output ports. Connected vias are used to form the sensing structure sensitivity. Some shield reject unwanted electric–field coupling. simulated, fabricated, measured demonstrate design rationality. results...

As the key element in near-field scanning, electromagnetic probes can locate and diagnose radiation from devices efficiently. To further improve measurement accuracy, different types of have been designed to performance terms bandwidth, spatial resolution, sensitivity. In this paper, two differential magnetic field are enhance sensitivity for scanning. The first probe has a simple U-shaped loop detection part. Based on as driven element, second incorporates identical loops parasitic elements...
