Special family of non-bijective multivariate maps Fn of Zm n into itself is constructed for n = 2, 3, . . . and compositem. The map Fn is injective on Ωn = {x|x1 + x2 + . . . xn ∈ Zm ∗} and solution of the equation Fn(x) = b, x ∈ Ωn can be reduced to the solution of equation zr = α, z ∈ Zm ∗, (r, φ(m)) = 1. The “hidden RSA cryptosystem” is proposed. Similar construction is suggested for the cas...

Shape description is one of the key parts of image content description in MPEG-7. Most of existing shape descriptors are usually either application dependent or non-robust, making them undesirable for generic shape description. In this paper, a generic Fourier descriptor (GFD) is proposed to overcome the drawbacks of existing shape representation techniques. The proposed shape descriptor is der...

Background and objectives: Cisplatin (CP), as an anticancer drug, causes nephrotoxicity. Zataria multiflora Boiss. (ZM), a plant which has been used as a herbal medicine for a variety of ailments. Our study aimed to examine the effects of ZM on cisplatin induced nephrotoxicity. Methods: Thirty-two male mice were randomly divided into four groups. The co...

Abstract Introduction Standard HSATs directly measure airflow and chest-movements to diagnose OSA. Indirect measures such as Cardiopulmonary-Coupling (CPC) now FDA approved “Software-as-a-medical-device” are gaining utilization. The assessment of CPC was from NPSG oximetry recordings which it compared. SleepImage (SI) recently made commercially available using ring-based oximetry. Out lab “real...

Let k = (k1, k2, · · · , kt) be a t-tuple of integers, and m be a positive integer. For a subset A ⊂ Zm and any n ∈ Zm, let rk A(n) denote the number of solutions of the equation k1a1 + · · ·+ ktat = n with a1, · · · , at ∈ A. In this paper, we give a necessary and sufficient condition on (k,m) such that there exists a subset A ⊂ Zm satisifying rk A = r k Zm\A. This settles a problem of Yang an...

Abstract The advances in biomedical imaging equipment have produced a massive amount of medical images that are generated by the different modalities. Consequently, huge volume data has been and caused complex time-consuming retrieving process relevant cases. To resolve this issue, Content-Based Biomedical Image Retrieval (CBMIR) system is applied to retrieve related from earlier patients’ data...

Background and objectives: Cisplatin (CP), a highly effective antineoplastic drug, causes testicular damage. Zataria multiflora Boiss. (ZM), a medicinal plant, has antioxidant and anti-inflammatory properties. The aim of this study was to investigate the effects of ZM against cisplatin-induced testicular toxicity. Methods: Thirty-two adult male mice wer...
