Two studies explored potential bases for reality monitoring (M. K. Johnson and C. L. Raye [see PA, Vol 65:6694]) of naturally occurring autobiographical events. In Study 1, subjects rated phenomenal characteristics of recent and childhood memories. Compared with imagined events, perceived events were given higher ratings on several characteristics, including perceptual information, contextual information, and supporting memories. This was especially true for recent memories. In Study 2, subjects described how they knew autobiographical events had (or had not) happened. For perceived events, subjects were likely to mention perceptual and contextual details of the memory and to refer to other supporting memories. For imagined events, subjects were likely to engage in reasoning based on prior knowledge. The results are consistent with the idea that reality monitoring draws on differences in qualitative characteristics of memories for perceived and imagined events (Johnson & Raye, 1981) and augment findings from more controlled laboratory studies of complex events (A. G. Suengas and M. K. Johnson [see PA, Vol 76:14478]; M. K. Johnson and A. G. Suengas, in press). (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

We synthesized and characterized new neutral and cationic palladium(II) complexes containing bis-(thio)ether ligands. The cationic compounds catalyzed the alternating CO/tert-butylstyrene copolymerization leading to polyketones with different degrees of stereoregularity depending on the nature of the S-S ligand. 相似文献

The Authors have developed a work of meta-analysis on the employment of IFN in the virus-correlated chronic hepatitis. They have examined World literature on: virus causing chronic hepatitis, type and duration of the treatment, criteria in the choice of the observed patients, clinical effects, effects on the virus, effects on the isto-pathologic situation. Have been considered the useful actions at the end of the treatment and in the follow-ups, so to evaluate the permanence of favourable effects. Have been also reminded the main collateral effects, even about frequency and intensity, as the various Authors relate. There are quite clear data indicating: efficacy in B-correlated chronic hepatitis greater than in C-correlated ones, greater efficacy in the treatments with Interferon with duration of more then 6 months in chronic hepatitis C. Doses greater than those generally employed appear not to give better results. The Authors moreover show the results of a clinical survey they made on patients with chronic hepatitis HBsAg+/HBeAg+ (treated with IFN-alpha 2r 5 MU t.i.w. for six months) and chronic hepatitis anti-HCV+ (treated with IFN-alpha 2r 3 MU t.i.w. for six months). The results confirm the efficacy of IFN in B-correlated chronic hepatitis (50% of sustained response) and its scarce efficacy in C-correlated chronic hepatitis for treatment shorter than 12 months (9.1% of sustained response). 相似文献

Hybrid organic–inorganic halide perovskites have emerged at the forefront of solution‐processable photovoltaic devices. Being the perovskite precursor mixture a complex equilibrium of species, it is very difficult to predict/control their interactions with different substrates, thus the final film properties and device performances. Here the wettability of CH3NH3PbI3 (MAPbI3) onto poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) hole transporting layer is improved by exploiting the cooperative effect of graphene oxide (GO) and glucose inclusion. The glucose, in addition, triggers the reduction of GO, enhancing the conductivity of the PEDOT:PSS+GO+glucose based nanocomposite. The relevance of this approach toward photovoltaic applications is demonstrated by fabricating a hysteresis‐free MAPbI3 solar cells displaying a ≈37% improvement in power conversion efficiency if compared to a device grown onto pristine PEDOT:PSS. Most importantly, VOC reaches values over 1.05 V that are among the highest ever reported for PEDOT:PSS p‐i‐n device architecture, suggesting minimal recombination losses, high hole‐selectivity, and reduced trap density at the PEDOT:PSS along with optimized MAPbI3 coverage. 相似文献

Abstract. This article describes a polynomial estimation technique based on the state‐space model and develops an estimation method for the quadratic estimation problem by applying the multivariate recursive least squares (RLS) Wiener estimator to the quadratic estimation of a stochastic signal in linear discrete‐time stochastic systems. The augmented signal vector includes the signal to be estimated and its quadratic quantity. The augmented signal vector is modelled in terms of an autoregressive model of appropriate order. A numerical simulation example for the speech signal as a practical stochastic signal is implemented and its estimation accuracy is found to be considerably improved in comparison with the existing RLS Wiener estimators. The proposed method may be applied advantageously to the quadratic estimations of wide‐sense stationary stochastic signals in general. 相似文献

We propose a new approach for converting light energy into electrical energy, based on the photogeneration of nano-dipoles at donor-acceptor interfaces. The nano-dipoles are oriented in space so as to contribute to a collective polarization that induces a potential difference across the material, sandwiched between electrodes. A current is detected in the external circuit upon illumination. Such a device would exploit many advantages of organic semiconductors and get rid of the main limitation, namely transport. We provide a proof of concept and we discuss the ideal limit of the device based on numerical simulations. This provides design guidelines to the achievement of best performances. Simulations show that the proposed device can be an appealing opportunity with giant conversion efficiency provided some technological issues are overcome. 相似文献

Emerging evidence has suggested that dysbiosis of the gut microbiota may influence the drug efficacy of colorectal cancer (CRC) patients during cancer treatment by modulating drug metabolism and the host immune response. Moreover, gut microbiota can produce metabolites that may influence tumor proliferation and therapy responsiveness. In this study we have investigated the potential contribution of the gut microbiota and microbial-derived metabolites such as short chain fatty acids and polyamines to neoadjuvant radiochemotherapy (RCT) outcome in CRC patients. First, we established a profile for healthy gut microbiota by comparing the microbial diversity and composition between CRC patients and healthy controls. Second, our metagenomic analysis revealed that the gut microbiota composition of CRC patients was relatively stable over treatment time with neoadjuvant RCT. Nevertheless, treated patients who achieved clinical benefits from RTC (responders, R) had significantly higher microbial diversity and richness compared to non-responder patients (NR). Importantly, the fecal microbiota of the R was enriched in butyrate-producing bacteria and had significantly higher levels of acetic, butyric, isobutyric, and hexanoic acids than NR. In addition, NR patients exhibited higher serum levels of spermine and acetyl polyamines (oncometabolites related to CRC) as well as zonulin (gut permeability marker), and their gut microbiota was abundant in pro-inflammatory species. Finally, we identified a baseline consortium of five bacterial species that could potentially predict CRC treatment outcome. Overall, our results suggest that the gut microbiota may have an important role in the response to cancer therapies in CRC patients. 相似文献

High-Pressure Processing Technologies for the Pasteurization and Sterilization of Foods 总被引:2,自引:0,他引:2

The food-processing industry has made large investments in processing facilities relying mostly on conventional thermal processing
technologies with well-established reliability and efficacy. Replacing them with one of the novel alternatives recently developed
is a decision that must be carefully approached. Among them, high-pressure processing (HPP), at room or refrigerated temperature,
is now a well-established option experiencing worldwide commercial growth. Surveys have shown an excellent consumer acceptance
of HPP technology. For financial feasibility reasons, HPP treatments must be kept short, a challenge that can be met by some
of the alternatives here reviewed such as the use of the hurdle technology concept. Although HPP technology is limited to
pasteurization treatments, the combination of high pressure and high temperature used in pressure-assisted thermal processing
(PATP) can be used to sterilize foods. An analysis of alternatives to achieve the inactivation of bacterial spores at the
lowest temperature possible highlights the need for additional research on the use of germinants. Because of incomplete research,
PATP presents several implementation challenges, including the modeling of food temperature, the determination of inactivation
kinetics particularly for bacterial spores, and the prediction of chemical changes including the potential formation of toxic
compounds. 相似文献

Approaches for improving the profile of functional unsaturated fatty acids in pork products include dietary supplementation of pigs with functional oils. Little information is available to indicate the benefit of this approach in a processed and cooked pork product such as breakfast sausages. Therefore, the aim of the present study is to examine the fatty acid profile and oxidation level in cooked pork sausages, produced following dietary supplementation with CLA compared to sunflower oil (SFO). Fat and moisture percentages, total fatty acid profiles and TBARS were analysed. Fatty acid profiles were altered in the sausages following all treatments. While a stronger effect was seen for CLA treatments, addition of SFO in the diet also resulted in linear increases of CLA in the sausages. CLA supplementation resulted in increased saturated fatty acid content; however, all treatments were within the recommended polyunsaturated/saturated fatty acid ratio of above 0.4. Improved oxidative stability was observed in sausages from CLA supplemented diets. 相似文献
