PROC SQL is SAS’ implementation of the ANSI Standard Query Language (SQL), an ANSI standard database programming/query language. Syntax is simple and its utility is broad in scope. As another capability, we find that PROC SQL is a very useful tool to perform exact test for monotonic trend in mean responses of discrete random variables. In this paper, we show utilization of PROC SQL to construct...

Note to the reader: this document is a work in progress and continues to evolve rapidly. Certain aspects of the GENI architecture are not yet addressed at all, and, for those aspects that are addressed here, a number of unresolved issues are identified in the text. Further, due to the active development and editing process, some portions of the document may be logically inconsistent with others.

There are several methods to estimate fractal dimension in fractional Brownian motion model. In this paper, one of methods, the variance method, is analyzed detailedly, and some problems in the method are pointed out. To resolve the problems, an improved method is proposed. To validate the method, a comparing experiment of two methods is designed. In the experiment, a SPOT image is selected and...

Graphene has been demonstrated as a potential gas sensor material by many researches [1,2]. However, the strong binding energy between graphene and analyte molecules leads to an inefficient desorption and subsequently a poor reliability on sensing performance. Besides, the lack of semiconducting property of graphene also disables the modulation of the transport characteristics through light irr...

One of the enticing features common to most two-dimensional electronic systems that, in the wake of (and in parallel with) graphene, are currently at the forefront of materials science research is the ability to easily introduce a combination of planar deformations and bending in the system. Since the electronic properties are ultimately determined by the details of atomic orbital overlap, such...

Cell biomechanics mediates critical cell functions including proliferation, differentiation, gene expression, contraction, and migration. Moreover, cells sense and actively respond to the mechanical features of their microenvironment. Therefore, a precise characterization of the mechanical properties of cells and extracellular matrix (ECM) is needed to further our understanding of the cell-micr...

Profitability in the dairy industry is heavily dependent on the accuracy of progesterone (P4) measurement, with periodic assessment of hormone levels in herds being utilised to determine the most fertile ovulation time for artificial insemination [1]. Point of care and in-line instruments, coupling ELISA techniques with electrochemical detection have been explored in order to quantify P4 in bov...

German Aerospace Center (DLR), Berlin, 12489, Germany b Paul-Drude-Institut für Festkörperphysik, Berlin, 10117, Germany c Technische Universität Berlin, Berlin,10623, Germany Abstract— A terahertz absorption spectrometer with a quantum-cascade laser (QCL) for high-resolution molecular spectroscopy is realized. The spectrometer is based on highfrequency (up to 50 MHz) modulation of the QCL freq...

We have developed a highly stretchable tactile distribution sensor which requires no wiring in the sensing area by applying Electrical Impedance Tomography (EIT), a non-invasive tomography technique, on a stretchable conductive structure. We have shown that our proposed stretchable conductive structure can significantly improve the quality of pressure distribution measurements over dynamically ...
