data envelopment analysis (dea) is a mathematical programming-based approach for evaluates the relative efficiency of a set of dmus (decision making units). the relative efficiency of a dmu is the result of comparing the inputs and outputs of the dmu and those of other dmus in the pps (production possibility set). also, in data envelopment analysis various models have been developed in order to...

background : the aim of this study was to generate in silico 3d-structure of the envelope protein of ahfv using homology modeling method to further predict its conformational epitopes and help other studies to investigate its structural features using the model. methods : a 3d-structure prediction was developed for the envelope protein of alkhumra haemorrhagic fever virus (ahfv), an emerging ti...

We present sensitive $\rm NH_3$ (1,1)--(7,7) line images from the Karl G. Jansky Very Large Array toward successive shocks, which are associated with blueshifted outflow lobe driven by compact protobinary system L1157. Within a projection distance of 0.1 pc, our observations not only trace quiescent and cold gas in flattened envelope but also illustrate complex physical chemical processes that ...

Temporal envelope is the primary acoustic cue used in most cochlear implant (CI) speech processors to elicit speech perception for patients fitted with CI devices. Envelope compression narrows down envelope dynamic range and accordingly degrades speech understanding abilities of CI users, especially under challenging listening conditions (e.g., in noise). A new adaptive envelope compression (AE...

Abstract We propose and numerically demonstrate high Q-factor sensors based on all-dielectric metasurfaces, which are very sensitive to the change of refractive index surrounding media incident angle. By using light angular scanning method, metasurface symmetric tetramer can act as an excellent sensing platform for trace-amount molecules such protein A/G, 2, 4-DNT, 2D material graphene with hug...

Abstract A dual-band 28/38 GHz multiple-input multiple-output (MIMO) two elements antenna for the next 5G network is proposed in this paper. The single element composed of a slot monopole loaded with stub and small crescent an entire size 15 × mm 2 . are added to compose suggested configuration. One antennas printed on upper layer while other located it's back substrate improve coupling between...
