Digital transmitters (DTX) have gained interest in the past few years because of their potential to provide compact die area, better efficiency due to the switching nature of the power amplifier core, and scaling with CMOS technology [1-3]. Quadrature DTX architecture [1] is favored over polar [3] or outphasing [4] for wideband applications, such as WiFi,(More)
In a retrospective investigation we found that the endogenous creatinine clearance (Ccr) of 35 nephrectomized patients was lower than that of normal people of comparable age with two intact kidneys. The Ccr level in the post-nephrectomy patients appeared to correlate with the age of the patients at the time of nephrectomy. The average Ccr value was 99.2(More)
We present the fabrication and characterization of plates made from two ultrathin layers and capable of withstanding repeated extreme mechanical deformation. The ultrathin layers, one flat and the other corrugated, are less than 100 nm thick and created using atomic layer deposition, forming a joined structure similar to conventional honeycomb sandwich(More)
Lenders face great uncertainty because of the information asymmetry problem in peerto-peer (P2P) marketplaces. This paper studies an online feature on a P2P platform, which allows lenders to seek information directly from the borrower of a loan, and examines the impact of the direct lender-borrower communication on the funding outcomes and the loan(More)
Unusual mechanical properties of mechanical metamaterials are determined by their carefully designed and tightly controlled geometry at the macro- or nanoscale. We introduce a class of nanoscale mechanical metamaterials created by forming continuous corrugated plates out of ultrathin films. Using a periodic three-dimensional architecture characteristic of(More)
We have used synchrotron X-ray scattering to study the homoepitaxial growth on Ag(001) and Ag(111) at low temperatures. For both orientations, our specular reflectivity data show that a large surface-normal compressive strain is uniformly distributed in the films deposited at T<200K. We attribute the strain to the incorporation of a considerable vacancy(More)
