We calculated rates of ventilator-associated pneumonia (VAP) by using surveillance data, clinical data, and codingdata. Compared with the VAP rates calculated on the basis of surveillance data, the VAP rates calculated on the basis of codingdata were significantly overestimated in 4 of 5 intensive care units. Efforts to improve coding and clinical documentation will address much but not all of this discrepancy between surveillance and administrative data. Infect Control Hosp Epidemiol 2010;31(6): 650-652

A bionumeric code, used by the BCF [Bureau of Commercial Fisheries] Exploratory Fishing Base in Pascagoula, Miss. is presented and discussed. The basic code consist of 9 digits divided into phylum-class, class-order, family, genus, and species categories. The code, a modification of one proposed by the FAO [Food and Agricultural Organization] in 1960, has facilitated the handling of large quantities of faunal data from the southwestern North Atlantic, Gulf of Mexico, and the Caribbean Sea. Expansion capabilities are inherent in the code structure and are discussed. Comparisons are also made with several code systems previously suggested by other workers. The present need for bionumeric coding systems is emphasized and a suggestion is made for establishing a central agency wherein all taxonomic records would be maintained and coded.

A new procedure for coding quantitative measurements and ranges of measurements onto discrete characters suitable for input into existing cladistic analyses programs is presented. The procedure consists of rank ordering the ranges by their minimum values first, then by their midrange values. The rationale for coding ranges is presented and justified from the taxonomist''s point of view. A detailed example is given and tested on a data set consisting of nine species of the genus Hordeum. Cladistic programs that deal directly with intra-OTU [operational taxonomic unit] variability are needed.

the use of homomorphic encryption to ensure computational security imposes additional overhead associated with encryption and decryption of data. One of the mechanisms that can be used to increase the data coding rate is the quadratic residue number system. The quadratic residue number system reduces the number of decimal multiplications by half when multiplying two complex numbers. However, the use of a quadratic residue number system imposes a number of restrictions related to the representation of a number. In this article, we propose a mechanism for choosing the parameters of a quadratic residue number system and develop an efficient data encoding algorithm

The issue of data security is one of the key issues of using homomorphic data encryption algorithms. In this article, we investigate the computational indistinguishability of the homomorphic encryption scheme BFV. We propose a scenario in which attackers can find out the secret key, which can potentially lead to information leakage. We show that the postulate of the BFV scheme to increase the level of security by introducing an additional error is erroneous.

A technique to save the frequency of write operation on the nonvolatile memory is proposed for reducing dynamic power dissipation of nonvolatile logic LSI which shortens its break-even time for power gating. The proposed technique is realized by combining a selective write method with a coding technique. The selective write method compares input words and stored words, and rejects redundant write operation. Moreover, the use of the data coding technique shortens the Hamming distance between adjacent words in an input data sequence and reduces the frequency of bit reversal in the nonvolatile memory, which results in the further reduction in the power dissipation due to write operation. Through the design and evaluation of a nonvolatile 8-bit counter, it is observed that the proposed technique shortens the break-even time for power gating by up to 85.2% with a small hardware overhead.

The conventional wisdom of an ideal omnidirectional antenna is an old academic idea, which is not practical nor useful in most mobile environments, as is well known to practicing engineers in wireless telecommunications. In the past five years, a wide variety of data compression, modulation and coding schemes have led to larger bit errors in wireless signals, while the communications environments are increasingly polluted with higher noises and interferences. Today, with the rapid advent of high-performance lowcost RF devices and software, as driven by the global commercial wireless markets, the production and deployment of smart wearable antennas are both practical and necessary. This paper discusses key issues on smart broadband body-wearable antennas, in particular signal fading, which can be effectively mitigated by as much as 35 dB in a practical low-cost design.

Gordon and Smith (2004) do a great service by introducing innovative and creative quantitative methods that incorporate information from qualitative sources. It is nevertheless important to examine the conditions under which the proposed estimators will be useful in practice. These conditions prove to be surprisingly restrictive: with the possible exception of extremely low-information settings, virtually all of the cases of discernible causation must be coded as such, those codings must contain virtually no errors, and the process by which qualitative researchers produce evaluations of discernibility must conform to the authors' model of the qualitative data-generating process (QDGP) if the procedures are to retain any comparative advantage.
