Weak signal reception is a very important and challenging problem for communication systems especially in the presence of non-Gaussian noise,and in which case the performance of optimal linear correlated receiver degrades dramatically.Aiming at this,a novel uncorrelated reception scheme based on adaptive bistable stochastic resonance(ABSR)for a weak signal in additive Laplacian noise is investigated.By analyzing the key issue that the quantitative cooperative resonance matching relationship between the characteristics of the noisy signal and the nonlinear bistable system,an analytical expression of the bistable system parameters is derived.On this basis,by means of bistable system parameters self-adaptive adjustment,the counterintuitive stochastic resonance(SR)phenomenon can be easily generated at which the random noise is changed into a benefit to assist signal transmission.Finally,it is demonstrated that approximately 8dB bit error ratio(BER)performance improvement for the ABSR-based uncorrelated receiver when compared with the traditional uncorrelated receiver at low signal to noise ratio(SNR)conditions varying from-30dB to-5dB. 展开更多

It is necessary to regularly assess patient satisfaction. The aim of this study was to assess the level of satisfaction of customers aged over 18 years attending the emergency department of the health center. Methodology This was a descriptive and analytical cross-sectional study of patients aged 18 years and over, who attended the Samu Municipal emergency department between 02 and 30 May 2023. The satisfaction index was determined using the adapted 2009 SAPHORA-MCO questionnaire and the Likert satisfaction scale. Results A total of 400 patients were surveyed. The average age was 35 years, with a standard deviation of 14.7. Of those surveyed, 51% were women, 87% were educated, 50% lived in Grand Yoff and 59.5% were unemployed. Satisfaction levels linked to perception of the cost of care (72%), waiting time (64.3%), information given to patients (69.1%) and pain management (74 .5%) are fair. On the other hand, the levels of satisfaction linked to administrative procedures (82.5%), staff attitudes towards patients (84%), staff availability (86.4%), patient privacy (89.2%), general atmosphere (87.2%), staff competence (87.3%), and the effectiveness of care (89.4%) were satisfactory. The average waiting time was 38 minutes. However, 32% of patients waited less than 30 minutes and 92% less than an hour. The satisfaction index linked to administration and reception was 72.9% and 79.85%, respectively. The satisfaction index linked to the administration and technical quality of care is equal to 85.8% and 83.7%, respectively. The overall satisfaction index is equal to 80.6%;the level of satisfaction of users of the health structure is satisfactory. Conclusion Patient satisfaction is an essential part of quality care. Patient satisfaction must be based on effective communication from the healthcare team and the creation of a patient-caregiver relationship. 展开更多

Objective] This study aimed to investigate the relationship between pistil-late flower developmental morphology and stigma receptivity in Euphorbia pulcherri-ma. [Method] One-year-old adult plants of E. pulcherrima cultivar ‘Mil enium’ were used as experimental materials to analyze pistil ate flower development process by macroscopic and scanning electron microscope (SEM) observation. Stigma receptivity was detected with benzidine-hydrogen peroxide method and in vivo pol en germina-tion method. [Result] The pistil ate flower development process of E. pulcherrima was consisted of columnar stigma phase, stigma lobe slightly opening phase, Y-shape stigma lobe phase, inverse V-shaped stigma lobe phase and stigma curling phase. Pistil ate flower development and stigma receptivity of E. pulcherrima exhibit-ed certain correlation. The stigma receptive period lasted from stigma lobe slightly opening phase to inverse V-shaped stigma lobe phase; inverse V-shaped stigma lobe phase was appropriate for pol ination, lasting for 3-5 d, with V-shaped stigma lobe and a large amount of exudates on stigma surface according to SEM obser-vation. Stigma receptivity of E. pulcherrima detected with benzidine-hydrogen perox-ide method was consistent with that detected in vivo pol en germination method. [Conclusion] ln breeding practice, the optimal pol ination period of E. pulcherrima can be determined based on the developmental morphology of pistil ate flower. 展开更多

[Objective] The primary aims of this study were to understand the characteristic of floralorgan development in ‘Dongxing', and analyze its differences with other apricot varieties. [Method] Floral organ morphology, pollen quantity, pollen viability and stigma receptivityof ‘Dongxing' and other apricot varieties were observed and measured. [Result] The ratio between the medium style and long style of‘Dongxing' was 82.4%, and the ratio of pistillode was lower than that in the other apricot varieties. Its pollen quantity was 32 183.2 grains per flower, and was fewer than the others. The pollen germination of ‘Dongxing' in optimum medium(1% agar +15% sucrose + 0.01% boric acid) was 53.0%, i.e. its pollen viability was low. The pollen viability increased at first and then decreased following the period of the bud stage to flowering stage, and pollen viability reached maximum value at the 1st d after flowering. Meanwhile the stored pollen viability continuously decreased with the extension of storage time, and pollen viability of the both vivo or vitro stored was decreased to the half of the maximum value at the 3rdd after flowering or storage.The stigma receptivity of ‘ongxing' enhanced at first then weakened, maximum stigma receptivity was found at the period of 2 h to 4 h after flowering. The optimum time for artificial pollination was 1 h to 8 h after flowering and it was shorter than the other apricot varieties was. [Conclusion] The ratio between the medium style and long style of ‘Dongxing' was higher than the other apricot varieties, while the pollen viability of ‘Dongxing' on the contrary. Its pollen viability reached maximum value at the 1st d after flowering and the optimum time for artificial pollination was1 h to 8h after flowering. 展开更多

Methods A total of 5 healthy women were followed for one control and one treatment cycle. In the treatment cycle, a dose of 10 mg RU486 was administered on day luteinizing hormone (LH)-2. In both the control and treatment cycle, an endometrial biopsy was obtained on LH+7. These biopsies were assessed by immunohistochemical analysis to find the difference in expression of integrins and progesterone receptor (PR) between the control and treatment cycle. Results The treatment with RU486 increased the expression of α 1 and α 4 subunits of integrin in glandular epithelial cells, but did not influence β 3 subunit. Moreover, the normal down regulation of PR in epitherial cell nuclei was inhibited by 10 mg RU486. Conclusion Single dose of 10 mg RU486 impairs the establishment of endometrial receptivity on time. 展开更多

Objective To establish the mice model of implantation dysfunction and to study the endometrial receptivity during implantation in implantation dysfunction mouse. Methods Sexually mature female virgin, Kunming mice were randomly assigned to the control group and the model group postcoitally. The model mice at 9 : 00 AM on d 4 of pregnancy(d 4) were injected subcutaneously with mifepristone. All animals were sacrificed at 9 :00 PM on d 4 and their uterine horns were examined for the presence of implanted embryos. Histopathology of uterine endometrium was observed by light-microscope. The endometrial expressions of estrogen receptor (ER) and progesterone receptor (PR) assessed by immunnohistochemical SP method. The endometrial expressions of ER mRNA and PR mRNA were assessed by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR). Results Compared with control group, implantation rates and average embryo num- ber significently decreased in model group, the development of endometrium was inhibited. In model group, absorbency and area rate of ER and PR in the gland and stroma were lower than those in control group (P〈0.05). Expressions of ER mRNA and PR mRNA in model uterus were significantly lower than those in the control. Conclusion The endometrial receptivity and implantation decreased in mifepristoneinduced implantation dysfunction mouse. 展开更多

Drawing upon the theory of reception aesthetics, this dissertation aims to discuss the translator's translation of You Can YouWill. Beginning with preliminary background information, e.g. the source book and writer, the translator further introduces theories andprevious related research, including Christian work. There are two representatives of reception theory; the translator stresses Jauss' per-spective of reception aesthetics, detailing his two key notions: the reader's decisive role and horizon of expectation. These notions shiftthe focus from the writer and text to the reader, which is a proven method to make the translation more acceptable to readers. Based onthe translation brief, target readers are Christians. During the translation process, the translator keeps key notions of reception aestheticstop-of-mind and strives to produce a version suitable for Christian readers. Some strategies, e.g. domestication and footnoting, are em-ployed to discuss the translation of biblical terms, Christian expressions, verses or stories from the Bible, metaphors and cultural items.In addition to these strategies, all translation is in accordance with CUV when encountering Bible-related text, due to CUV's authorityamong all versions of the Bible. Lastly, the translator provides conclusive remarks based on analysis as well as suggestions for further re-search. Limitations of this study are also mentioned. 展开更多

Background: Recent studies have revealed that noncoding RNAs play important regulatory roles in the formation of endometrial receptivity.Circular RNAs(circRNAs) are a universally expressed noncoding RNA species that have been recently proposed to act as miRNA sponges that directly regulate expression of target genes or parental genes.Results: We used Illumina Solexa technology to analyze the expression profiles of circRNAs in the endometrium from three goats at gestational day 5(pre-receptive endometrium,PE) and three goats at gestational day 15(receptive endometrium,RE).Overall,21,813 circRNAs were identified,of which 5,925 circRNAs were specific to the RE and 9,078 were specific to the PE,which suggested high stage-specificity.Further analysis found 334 differentially expressed circRNAs in the RE compared with PE(P < 0.05).The analysis of the circRNA-miRNA interaction network further supported the idea that circRNAs act as miRNA sponges to regulate gene expression.Moreover,some circRNAs were regulated by estrogen(E2)/progesterone(P4) in endometrial epithelium cell lines(EECs) and endometrial stromal cell line(ESCs),and each circRNA molecule exhibited unique regulation characteristics with respect to E2 and P4.Conclusions: These data provide an endometrium circRNA expression atlas corresponding to the biology of the goat receptive endometrium during embryo implantation. 展开更多

Chatter has been a primary obstacle to the successful implementation of high speed machining.The frequency response function(FRF) of the tool point is crucial for identification of chatter free cutting conditions.In order to quickly acquire the FRF of the different components combinations of machine tool,the assembly of machine tool was always decomposed into several parts,where the fluted portion of tool,however,was always treated as a uniform beam,and the associated discrepancy was ignored.This paper presents a new method to predict the dynamic response of the machine-spindle-holder-tool assembly using the receptance coupling substructure analysis technique,where the assembly is divided into three parts:machine-spindle,holder and tool shank,and tool's fluted portion.Impact testing is used to measure the receptance of machine-spindle,the Timoshenko beam model is employed to analyze the dynamics of holder and tool shank,and the finite element method(FEM) is used to calculate the receptance of the tool's fluted portion.The approximation of the fluted portion cross section using an equivalent diameter is also addressed.All the individual receptances are coupled by using substructure method.The predicted assembly receptance is experimentally verified for three different tool overhang lengths.The results also show that the equivalent diameter beam model reaches an acceptable accuracy.The proposed approach is helpful to predict the tool point dynamics rapidly in industry. 展开更多

In order To evaluate whether the parameters of spiral artery blood flow, as measured by transvaginal color Doppler, may be used to assess endometrium receptivity prior to embryo transfer (ET), a retrospective study of 94 infertile women who had undergone ART treatments with different outcomes (pregnant or nonpregnant) was done. Subendometrial blood flow was evaluated. The resistance index (RI), systolic/diastolic ratio (S/D) and pulsatility index (PI) were significantly lower in those who achieved pregnancy as compared with those who did not: 0.62±0.04 vs 0.68±0.04 (P<0.001), 2.66±0.33 vs 3.19±0.39 (P<0.01) and 1.15±0.17 vs 1.34±0.22 (P<0.05), respectively. Furthermore, when RI>0.72, PI>1.6, and S/D>3.6, no pregnancy occurred. These data suggest that the parameters of spiral artery blood flow could be used as a new assay in predicting endometrial receptivity before ET. 展开更多

The hypersonic boundary-layer receptivity to slow acoustic waves is investigated for the Mach 6 flow over a 5-degree half-angle blunt cone with the nose radius of 5.08 mm. The plane acoustic wave interacts with the bow shock, and generates all types of disturbances behind the shock, which may take various routes to generate the boundarylayer unstable mode. In this paper, two routes of receptivity are investigated in detail.One is through the disturbance in the entropy layer. The other is through the slow acoustic wave transmitted downstream the bow shock, which can excite the boundary-layer mode due to the synchronization mechanism. The results show that, for a low frequency slow acoustic wave, the latter route plays a leading role. The entropy-layer instability wave is able to excite the first mode near the neutral point, but its receptivity efficiency is much lower. 展开更多
