An Online Induction Algorithm for Internal Contextual Grammars Using Restarting Automata
No full textAbstractIn this paper, we propose a new algorithm to induce an internal contextual grammar from positive examples using restarting automata. Motivation comes from, real-time systems which induce the target grammar within a deadline. In our algorithm, we deal with real time inputs which are generated by internal contextual grammar. Principally grammatical inference and grammar induction are considered equivalent but there is a slight difference, in this paper we concentrate on that difference. Here initially our algorithm will concentrate on grammatical Inference but at last it will be ended up with the concept of grammar induction. In order to induce the grammar, we first obtain insertion rules by scanning an input at a particular time unit. The insertion rules are converted into contextual rules. This set of contextual rules will be a guess about the grammar without taking care of over generalization. Further we will check the correctness of the contextual rules using restarting automata for the next input string and we update the rules based on need, that is called correction phase. After getting the final time-unit/deadline as an input, the algorithm executes some steps on the induced grammar to prune the over generalization of strings. It produces the final grammar for the strings which are given within the final time-unit

Green synthesis of silver nanoparticles (AgNPs) with Hypericum wightianum : Characterization and evaluation of its antibacterial activity, antioxidant activity and toxicity assessment on Artemia salina
No full textIn the present study, in vitro H. wightianum plant extract was used for the phytosynthesis of AgNPs. It was observed that the reduction of aqueous silver ions (Ag+) to AgNPs was facilitated by the extract, resulting in the formation of stable AgNPs. The synthesized AgNPs were characterized through various spectroscopic and microscopic analyses. The nanoparticles showed a sharp absorbance peak at 480 nm on UV-Vis spectroscopy. Fourier Transform Infrared Spectroscopy (FTIR) confirms the presence of flavonol, glycosides and phloroglucinols. X-ray diffraction (XRD) was used to characterize the reduction of silver ions to silver element. It shows the different distinct peaks at 25.78 °, 39.41 °, 41.37 ° and 76.26 ° correspond to the (0 1 2), (1 1 1), (1 0 1) and (3 1 1) planes of standard XRD peak reflections of silver crystal. The formation of monodispersed low polydispersity nanoparticles (16.47 nm) was revealed by the transmission electron micrograph (TEM) and energy-dispersive X-ray spectroscopy (EDX) analysis confirms the presence of elemental silver. AgNPs showed good antioxidant properties in DPPH (2, 2-diphenyl-1-picrylhydrazyl), hydrogen peroxide (H2O2), nitric oxide (NO) radical scavenging and ferric reducing power assays. This result proved that AgNPs have strong antioxidant activity, which is comparable to the standard. Antioxidant activity of AgNPs increased dose-dependently, based on the reduction of electron or hydrogen acceptors. Antibacterial activity of AgNPs was demonstrated against test strains, showing significant inhibition. A maximum zone of inhibition of 15 mm was observed against Staphylococcus aureus, followed by 14 mm against Pseudomonas aeruginosa at 80 µg/mL concentration. The AgNPs showed moderate toxicity against A. salina. The present study demonstrates the potential of in vitro H. wightianum extract for the phytosynthesis of AgNPs with antioxidant, antibacterial and moderate toxicity properties
Novel mutation in the glycoprotein Ibβ in a patient with Bernard-Soulier syndrome: Possibility of distant parental consanguinity
No full textBernard-Soulier syndrome (BSS) is a rare autosomal recessive disorder characterized by a prolonged skin-bleeding time and thrombocytopenia with giant platelets. The hallmark of BSS is an abnormal platelet attachment to the vessel wall due to reduced or abnormal glycoprotein Ib-IX-V complex. We present a case of BSS in a 14-month-old boy caused by a novel genetic mutation. The patient has the typical clinical findings of BSS, but he was misdiagnosed for a long period. Evaluation of the peripheral blood smear revealed giant platelets and genetic testing confirmed the diagnosis of BSS. The child was found to be homozygous for a nonsense mutation (c.423CA) in the glycoprotein Ibβ (GPIbβ) gene. Knowing that we are dealing with a very rare syndrome, the detected mutation in our patient was homozygous. Although the parents were nonconsanguineous, we believe that they were related in a distant parental connection, which the parents and their family were not aware of. © 2012 Wolters Kluwer Health | Lippincott Williams and Wilkins.Bowers MJ, 2006, BLOOD COAGUL FIBRIN, V17, P409, DOI 10.1097-01.mbc.0000233372.33852.12; DELASALLE C, 1995, NOUV REV FR HEMATOL, V37, P215; Hillmann A, 2002, THROMB HAEMOSTASIS, V88, P1026; Kunishima S, 2006, EUR J HAEMATOL, V76, P348, DOI 10.1111-j.1600-0609.2005.00612.x; Kunishima S, 2002, INT J HEMATOL, V76, P319, DOI 10.1007-BF02982690; Lanza F, 2006, ORPHANET J RARE DIS, V1, DOI 10.1186-1750-1172-1-46; LOPEZ JA, 1992, J BIOL CHEM, V267, P12851; Lopez JA, 1998, BLOOD, V91, P4397; Pham A, 2007, ARCH PATHOL LAB MED, V131, P1834; Poujol CR, 2002, EXP HEMATOL, V30, P352, DOI 10.1016-S0301-472X(02)00774-9; Rand ML, 2010, AM J HEMATOL, V85, P584, DOI 10.1002-ajh.21768; Sachs UJH, 2003, BRIT J HAEMATOL, V123, P127, DOI 10.1046-j.1365-2141.2003.04554.x; Sandrock K, 2010, TRANSFUS MED HEMOTH, V37, P278, DOI 10.1159-000320255; Savoia A, 2011, HAEMATOL-HEMATOL J, V96, P417, DOI 10.3324-haematol.2010.032631; Strassel C, 2006, J THROMB HAEMOST, V4, P217, DOI 10.1111-j.1538-7836.2005.01654.x; Sumitha E, 2011, J THROMB HAEMOST, V9, P1590, DOI 10.1111-j.1538-7836.2011.04417.x11

Heterosis for economic traits in coconut (Cocos nucifera L.)
No full textField studies conducted for a period of 12 years to assess the traits responsible for yield performance and heterosis of twelve coconut hybrids in comparison with three varieties showed that among the hybrids, GBGD x ECT recorded the highest mean yield of 127.6 nuts palm-1 year-1 and was on par with ECT x GBGD (106.9 nuts palm-1 year-1), COD x LCT (108.0 nuts palm-1 year-1) and WCT x MYD (107.6 nuts palm-1 year-1). Hybrid GBGD x PHOT recorded the highest fruit length (23.9 cm) followed by ECT x GBGD (23.3 cm). The hybrid ECT x GBGD recorded the highest values for most of the fruit characteristics viz., fruit breadth (17.3 cm), fruit weight (1180.0 g), husked fruit weight (758.0 g) and copra weight (231.1 g). The variety ‘Laccadive Ordinary’ recorded higher oil content (71.1%) compared to its hybrids, LCT x GBGD (70.8%), COD x LCT (70.0%) and LCT x COD (69.8%). Hybrids displayed substantial differences in their heterotic response for nut characters. The highest yielding hybrid, GBGD x ECT excelled its standard check by 40.8 per cent followed by LCT x COD (39.4%)
