Design and investigation of pocket shaped fractal antenna using circular ring elements for UWB technology with stub loaded DGS
TL;DR: In this article , a modified ground plane has been modified for attaining the improved results, which reveals the wider impedance bandwidth of 11.80 GHz and 14.67 to 20.0 GHz in the UWB frequency band.
Fabrication Effects on Polysilicon-based Microcantilever Piezoresistivity for Biological Sensing Application (Kesan Proses Fabrikasi Terhadap Piezorintangan Mikrokantilever Berasaskan Bahan Polisilikon untuk Aplikasi Penderiaan Biologi)
TL;DR: In this paper, four different type of polysilicon-based piezoresistive microcantilever sensors were designed to increase the sensitivity of the micro cantilevers sensor because the forces involved is very small.

Modified Hamming function weighted waveguide structure for the broadband and minimized mismatched optical couplers
Abstract: We numerically investigate a new function modified from Hamming function to apply in weighting the waveguide structure of a mismatched optical coupler with the characteristics of low crosstalk, short length, and broad C+L-band. The full factorial design and beam propagation method are being used to seek the optimal structure parameters of coupling waveguide. This modified Hamming weighting function (M-HWF) is proved to have the superior performances to Hamming weighting function (HWF) in several ways. In theoretical computation, the M-HWF and HWF waveguides have the coupling lengths of 11 mm and 16 mm, respectively at crosstalk of -40 dB and operating wavelength of 1.57 μm. After the numerical design of waveguide structure parameters, the M-HWF also obtain a shorter coupling length of 4.50 mm than coupling length of 5.90 mm of HWF at crosstalk of -40 dB and within the C+L-band (1.53∼1.61 μm). The M-HWF waveguide with the shortest coupling length of 4.5 mm can even reach a broader bandwidth between 1.50 and 1.70 μm.

The moderator–mediator variable distinction in social psychological research: Conceptual, strategic, and statistical considerations.
Reuben M. Baron,David A. Kenny +1 more
TL;DR: This article seeks to make theorists and researchers aware of the importance of not using the terms moderator and mediator interchangeably by carefully elaborating the many ways in which moderators and mediators differ, and delineates the conceptual and strategic implications of making use of such distinctions with regard to a wide range of phenomena.

The CES-D Scale: A Self-Report Depression Scale for Research in the General Population
TL;DR: The CES-D scale as discussed by the authors is a short self-report scale designed to measure depressive symptomatology in the general population, which has been used in household interview surveys and in psychiatric settings.
