A lensless Vanderlugt optical correlator using two phase-only spatial light modulators （SLMs） is proposed. The SLMs are used for displaying input and filter patterns respectively. The SLMs are also used as programmable lenses in order to realize the lensless construction. This lensless system is simple and its alignment adjustment is easy. The performance of the SLMs as programmable lenses is also described.

High-resolution modeling approach is increasingly being considered as a necessary step for improving the monitoring and predictions of regional air quality. This is especially true for highly urbanized region with complex terrain and land-use. This study uses Community Multiscale Air Quality （CMAQ） model coupled with MM5 mesoscale model for a comprehensive analysis to assess the suitability of such high-resolution modeling system in predicting ozone air quality in the complex terrains of Osaka, Japan. The 1-km and 3-kin grid domains were nested inside a 9-km domain and the domain with 1-km grid covered the Osaka region. High-resolution Grid Point Value-Mesoscale Model （GPV-MSM） data were used after suitable validation. The simulated ozone concentrations were validated and evaluated using statistical metrics using performance criteria set for ozone. Daily maxima of ozone were found better simulated by the 1-krn grid domain than the coarser 9-km and 3-km domains, with the maximum improvement in the mean absolute gross error about 3 ppbv. In addition, 1-km grid results fared better than other grids at most of the observation stations that showed noticeable differences in gross error as well as correlation. These results amply justify the use of the integrated high-resolution MM5-CMAQ modeling system in the highly urbanized region, such as the Osaka region, which has complex terrain and land-use.

In this paper, a decentralized proportional-derivative （PD） controller design for non-uniform motion of a Hamiltonian hybrid system is considered. A Hamiltonian hybrid system with the capability of producing a non-uniform motion is developed. The structural properties of the system are investigated by means of the theory of Hamiltonian systems. A relationship between the parameters of the system and the parameters of the proposed decentralized PD controller is shown to ensure local stability and tracking performance. Simulation results are included to show the obtained non-uniform motion.

To the Editor:Biliary drainage is essential for controlling cholangitis and/or jaundice in patients with malignant hilar biliary obstruction,and endoscopy is the first choice of approach due to its less *** unresectable cases,placement of self-expandable metal stents(SEMSs)has been recommended over that of plastic stents due to their longer patency,and bilateral placement is also recommended to achieve higher clinical success and patency rates[1].

Objective: To investigate the influence of calcium carbonate supplementation on cognitive function in mice. Methods: Mice were fed diets containing 1.0% calcium carbonate for 8 weeks, following which they were evaluated for memory function using object recognition, Y-maze, and Barnes maze tests. Next, the expression levels of cAMP response element binding protein(CREB) and phosphorylated CREB, which is involved in the memory process were investigated in both the hippocampus and cerebral cortex using western blotting methods. Results: Mice fed on a diet containing calcium carbonate showed memory impairments in object recognition, Y-maze, and Barnes maze tests with respect to the mice that were on a control diet. Further, mice that were fed a diet containing calcium carbonate and a nimodipine(an L-type calcium channel antagonist), reversed calcium carbonate-induced memory impairments, thus suggesting that excessive entry of calcium in cells may cause memory impairments. A study using western blot revealed that expression of CREB and phosphorylated CREB in hippocampus and cerebral cortex was significantly lower in the calcium carbonatefed mice than in the control-diet-fed mice. Conclusions: These results suggest that a calcium carbonate diet may cause memory impairment by decreasing CREB expression. This is the first report of calcium carbonate supplementation causing memory impairment. This simple animal model may be useful as a novel cognitive impairment model for drug development.

Objective: To investigate whether the extract from the nacreous layer of pearl oysters(nacre extract) improves impairments in memory caused by scopolamine administration in ***: Nacre extract was prepared from the inner shell layer of pearl oyster. Effects of nacre extract on scopolamine-induced memory impairment were estimated using novel object recognition test, Y-maze test, and Barnes maze test Effect of nacre extract on mRNA expressions which are genes associated with memory in the hippocampus was investigated using semi-quantitative reverse transcription polymerase chain reaction(RT-PCR) ***: Administration of nacre extract led to the protection against scopolamine-induced impairments in object recognition, short-term memory, and spatial memory. Treatment with nacre extract reversed the mRNA expression of brain-derived neurotrophic factor(BDNF) and Homer protein homolog 1(Homer-1 a) in the hippocampus, which decreased with the treatment of scopolamine. Conclusions: These results suggest that nacre extract has attenuating effects on memory impairments induced by scopolamine through the increase in mRNA expression of BDNF and Homer-1 a.

Application of compost in agricultural practice could potentially cause contamination of foodstuffs with pathogenic bacteria such as Escherichia coli O157：H7 （E. Coli O157）. We investigated pathogenic bacteria in compost collected from the compost facilities, and evaluated the survival of E. coli K12 and O157 in laboratory experiments. Out of 19 compost product samples, coliform bacteria and salmonella were detected in 7 and 3 samples respectively. The number of coliform bacteria was 1.8 × 10^2 to 2.5 × 10^6 CFU/g dw and that of salmonella was 4.2 × 10^1 to 6.0 × 10^3 CFU/g dw. Moreover. coliform bacteria, fecal coliform, E. coli and salmonella were detected during composting at 54℃ to 67℃. The results indicated that moisture content was a very important factor to the heat sensitivity of pathogenic bacteria in compost, E. coli in compost of high moisture content was more sensitive than that in compost of low moisture content, cells harvested in logarithmic phase was more sensitive than these in stationary phase, and E. coli K12 was more sensitive than E. coli O157. Based on the D values, the lethal time of E. coli K12 and 0157 from 10^8 to 10^0 CFU/g dw were 16.3 and 28.8 min, respectively, at 60℃ in compost with 40% moisture content. However, some E. coli cells survived in composting process at 54℃ to 67℃. Water potential（low moisture content） and physiological aspects of bacteria（stationary phase） could explain only in part of the prolonged survival of E. coli in compost, and there should be some other factors that are conducive to bacterial survial in compost.
