Technology dependent logic optimization is usually carried through a sequence of design rewiring operations. In [18] a new design rewiring method is proposed that combines error diagnosis and correction techniques with ATPG. In this work, we examine its complexity and we arrive to a new set of results with interesting theoretical and practical applications. We also present experiments that conf...

DNA barcoding is a fast-developing technique to identify species by using short and standard DNA sequences. Universal selection of DNA barcodes in ferns remains unresolved. In this study, five plastid regions (rbcL, matK, trnH-psbA, trnL-F and rps4-trnS) and eight nuclear regions (ITS, pgiC, gapC, LEAFY, ITS2, IBR3_2, DET1, and SQD1_1) were screened and evaluated in the fern genus Adiantum from...

Although most plant species from algae to flowering plants use blue light for inducing phototropism and chloroplast movement, many ferns, some mosses, and green algae use red as well as blue light for the regulation of these responses, resulting in better sensitivity at low light levels. During their evolution, ferns have created a chimeric photoreceptor (phy3 in Adiantum) between phytochrome (...

The suitability and accuracy of using simple human immunodeficiency virus (HIV) rapid (SR) tests in community-based clinics in northwest Tanzania were determined to assess eligibility for participation in clinical trials. The HIV rapid and ELISA test results for 789 women aged 16 to 54 who were screened for two clinical trials of HIV prevention were compared. Women were offered voluntary HIV co...

In this paper we present the application of our ATPGbased design rewiring approach to multi-level combinational logic circuit optimization. At every step of this optimization procedure, we introduce a design error by removing the logic that violates the optimization constraint(s) and then we attempt to correct the design by modifying the logic somewhere else. We give heuristics and describe the...

Fault equivalence is an essential concept in digital VLSI design with significance in many different areas such as diagnosis, diagnostic ATPG, testability analysis and synthesis. In this paper, an efficient procedure to compute exact fault equivalence classes of combinational circuits is described. The procedure consists of two steps. The first step performs structural fault collapsing and uses...

AIM OF STUDY Adiantum, one of the most widely distributed genera of the family Pteridaceae, is employed in folk medicine worldwide. Adiantum latifolium Lam. has been used in Latin American traditional medicine as anxiolytic, analgesic and antiinflammatory. The present study investigates the antinociceptive and antiinflammatory properties of the methanolic extract of Adiantum latifolium (MEA) in...
