This paper studies fundamental aspects of modelling data using multivariate Watson distributions. Although these distributions are natural for modelling axially symmetric data (i.e., unit vectors where ±x are equivalent), for high-dimensions using them can be difficult—largely because for Watson distributions even basic tasks such as maximumlikelihood are numerically challenging. To tackle the ...

gbss protein, that is the product of waxy gene (wx) is one of the major enzyme in starch biosynthesis that controls the proportion of amylose to amylopechtine and its absence leads to production of starch with low amylose and higher amylopechtine content, called waxy starch.wx-a1, wx-b1, wx-d1 are three locuses in bread wheat (triticum aestivum) genome that encodes gbss protein and waxy starch ...

in this research, host stage preference of parasitoid wasp, aphidius matricariae haliday in choice and no-choice tests and functional response of the parasitoid were investigated on common wheat aphid, schizaphis graminum rondani on the alvand cultivar in laboratory conditions at 20, 25 and 30 °c, rh 70 ±10 % and a photoperiod of 16 h l : 8 h d. the maximum mean parasitisms in choice and no-cho...

the 1rs chromosome segment derived from petkus rye carries genes for resistance to three wheat rust diseases, namely lr26 for resistance to leaf rust (caused by puccinia triticina), yr9 for resistance to stripe rust (p.striiformis f. sp. tritici) and sr31 for resistance to stem rust (p. graminis f. sp. tritici). since sec-1 is tightly linked with the three rust resis-tance genes electrophoresis...

OBJECTIVES To explore the utility of home and community-based HIV testing and counseling (HTC) to increase detection of undiagnosed HIV among female spouses and children of HIV-positive PWID in Punjab province, Pakistan. DESIGN Between March 2014 and March 2015, home-based HTC was provided by a local NGO to spouses of HIV-positive PWID in Lahore, Faisalabad, and Sargodha. Convenience sampling...

a new and distinctive form belonging to the genus and subgenus eremias fitzinger, 1834 is reported from the highlands of alvand mountains, hamedan province, western iran at about 2700 m elevation. it is easily distinguished from all the other species of the typical subgenus (e. velox, e. persica, e. strauchi, e. nigrolateralis, e. lalezharica, e. afghanistanica, e. regeli, e. suphani, and e. ni...

To determine salt sensitivity for wheat at various growth stages, a factorial experiment arranged as randomized complete block design was conducted in the ambient environment at the National Salinity Research Center, Yazd, Iran. Treatment were two cultivars of wheat (Kavir & Roshan) and salinity imposed at emergence, tillering, stem elongation, spike emergence and one week after anthesis. A con...
