Multimedia Proxy caching (MPC) can improve scalability by reducing network load, and maximize delivered quality to heterogenous clients. The notion of delivered quality is a new dimension in design and evaluation of MPC mechanisms that does not exist in traditional web caching. Furthermore, there is a fundamental tradeoff between delivered quality, network load and delay. Previous studies on MP...

Let {Xk, k ∈ Z} be an autoregressive process of order q. Various estimators for the order q and the parameters q = (θ1, . . . , θq) are known; the order is usually determined with Akaike’s criterion or related modifications, whereas Yule–Walker, Burger or maximum likelihood estimators are used for the parameters q . In this paper, we establish simultaneous confidence bands for the Yule–Walker e...

The aim of this paper was to assess the effect of catechol (CH), as a peroxidase inhibitor, and 8-hydroxyquinoline citrate (HQC), as a bacterial inhibitor, on keeping the quality of Gerbera Jamesonii cv. Hongyan cut flowers, known to be limited by vascular occlusion. Blockage in the stem xylem vessels of cut gerbera was studied using light and scanning electron microscope. The results showed th...

Hardware implementation of partially-parallel Low-Density Parity-Check (LDPC) decoders using unstructured random matrices is very complex and requires huge hardware resources. To alleviate the complexity and minimize resource requirements, structured LDPC matrices are used. This paper presents a novel technique for constructing a multi-level Hierarchical Quasi-Cyclic (HQC) structured matrix for...

Therapeutic drug monitoring of immunosuppressive agents in organ transplanted Patient’s is crucial to prevent intoxication or transplant rejection due to inadequate dosage. The commonly used immune assays have been gradually undergoing replacement by mass spectrometry since this physical method offers both a higher Sensitivity and specificity. A simple rapid, novel, sensitive Ultra performance ...

ntroduction: ‘Perla’ and ‘Mexicano’ are varieties of tuberose grown in Mexico that have potential for commercialization export; however, no preservative solutions been evaluated to increase their shelf life. Objective: To determine physical, physiological, chemical changes occur postharvest when different applied. Methodology: Tuberose flower spikes Perla, with two open basal flowers, were plac...

We introduce Ouroboros, a new Key Exchange protocol based on coding theory. The protocol gathers the best properties of the recent MDPC-McEliece and HQC protocols for the Hamming metric: simplicity of decoding and security reduction, based on a double cyclic structure. This yields a simple, secure and efficient approach for key exchange. We obtain the same type of parameters (and almost the sam...

Disturbance in water relations is the major causes of vase life reduction and senescence in cut flowers This problem is mainly due to microorganism proliferation in the vase solution which leads to vascular occlusion and reduction in solution uptake by cut flowers. Therefore a comprehensive study was conducted to evaluate the biocidal effect of nano silver particles (NSP) and compare it with so...

Objetive: Describe research related to the use of antiparasitic drugs as likely treatment in COVID-19 based on scientific literature. Methods: This is a literature review that uses two platforms database: Pubmed and BIREME. Were included this study twelve published articles, from 2019 September 2020, which referred or were therapeutic alternative COVID-19. Results: The ivermectin, hydroxychloro...

As one of the main components of haze, topics with respect to PM2.5 are coming into people’s sight recently in China. In this paper, we try to predict PM2.5 concentrations in Dalian, China via symbolic regression (SR) based on genetic programming (GP). During predicting, the key problem is how to select accurate models by proper interestingness measures. In addition to the commonly used measure...
