TL;DR: In this paper, the authors propose to associate a received command with a control such as a push button on a mobile telecommunication device, and enable an action associated with the command to be performed when the control is later activated.
Abstract: The invention is directed to associating a received command with a control such as a push button on a mobile telecommunication device, and enabling an action associated with the command to be performed when the control is later activated. The command may be received from another mobile device or remote computer. The actions that may be associated with the performance instruction include tuning to a broadcast such as a radio or television, browsing a web site or hyperlinked text, and tuning to a streamed broadcast over a network, such as the Internet. The command button can be a physical element such as the '*' key on a keypad or a virtual button on a display.

TL;DR: In this paper, the effects of impurities on the optical behavior of CdTe have been investigated and various optical absorption mechanisms and their effects on optical behavior have been discussed in detail.
Abstract: 2014 CdTe is a material potentially useful for a number of optical applications. These include electrooptic modulation, high power laser windows, electroluminescence and photoconduction. In this review these and other uses will be described. Particular attention will be paid to the various optical absorption mechanisms and the effects of impurities on the optical behavior. Section II.2: Optical applications of CdTe. a) Infrared optics, luminescence, photoconductivity.

TL;DR: It is proved that spatial correlation does not affect the diversity order but that it reduces the array gain and hence increases the SER in the high SNR regime.
Abstract: This letter derives the asymptotic symbol error rate (SER) and outage probability of multiple-input multiple-output (MIMO) maximum ratio-combining (MRC) systems. We consider Rayleigh fading channels with both transmit and receive spatial correlation. Our results are based on new asymptotic expressions that we derive for the p.d.f. and c.d.f. of the maximum eigenvalue of positive-definite quadratic forms in complex Gaussian matrices. We prove that spatial correlation does not affect the diversity order but that it reduces the array gain and hence increases the SER in the high SNR regime

TL;DR: In this article, the authors provided a catalyst and a process for converting methanol or dimethyl ether to a product containing C2 to C4 olefins using a medium-pore zeolite.
Abstract: There are provided a catalyst and a process for converting methanol or dimethyl ether to a product containing C2 to C4 olefins. The catalyst comprises a porous crystalline material having a Diffusion Parameter for 2,2-dimethylbutane of 0.1-20 sec-1 when measured at a temperature of 120 °C and a 2,2-dimethylbutane pressure of 60 torr (8kPa). In addition, the catalyst is characterized by a hydrothermal stability such that, after steaming the catalyst at 1025 °C for 45 minutes in 1 atmosphere steam, the catalyst exhibits a methanol conversion activity of at least 50 % when contacted with methanol at a methanol partial pressure of 1 atmosphere, a temperature of 430 °C and 0.5 WHSV. The porous crystalline material is preferably a medium-pore zeolite, particularly ZSM-5, which contains phosphorus and has been severely steamed at a temperature of at least 950 °C.

TL;DR: A method of combining thin-layer chromatography with activation analysis to measure quantitatively the individual impurities in tricresyl phosphate (TCP) is described in this paper.
Abstract: A method of combining thin-layer chromatography with activation analysis to measure quantitatively the individual impurities in tricresyl phosphate (TCP) is described. The relative amounts and types of impurities found in commercial grades of TCP are discussed. Preparative thin-layer chromatography and iron powder chromatography are applied to produce TCP samples with known concentrations of several impurities. The use of the four-ball wear tester as a method of determining trends in wear values as a function of base stock and additive quality is demonstrated. The relationship of acid phosphate rather than TCP concentration to antiwear properties of compounded lubricants is suggested by transition load studies. Presented as an American Society of Lubrication Engineers paper at the ASLE/ASME Lubrication Conference held in Chicago, Illinois, October 17–19, 1967.
