Covering numbers of precompact symmetric convex subsets of Hilbert spaces are investigated. Lower bounds are derived for sets containing orthogonal subsets with norms of their elements converging to zero sufficiently slowly. When these sets are convex hulls of sets with power-type covering numbers, the bounds are tight. The arguments exploit properties of generalized Hadamard matrices. The resu...

The potato rot nematode, Ditylenchus destructor Thorne, is reported for the first time in hulls and seeds of peanut. The populations found differed from D. dipsaei and D. myceliophagus in habitat, number of lateral incisures, shape of tail tip, and length of postvulval sac. Infected hulls had brown necrotic tissue at the point of connection with the peg, and a black discoloration appeared first...

Sesame (Sesamum indicum Linn) is an underutilized oil seed in Nigeria. Two high yielding sesame seed cultivars (White -NCRI-98-60 and black-NCRI-97-28) were used in this study. Proximate composition, minerals, vitamins and anti nutritional factors of whole seeds, dehulled seeds and hulls were determined. Also, effects of processing namely soaking, germination, autoclaving, roasting and cooking)...

Endogenous sinapic acid (SA), sinapine (SP), sinapoyl glucose (SG) and canolol (CAN) of canola and mustard seeds are the potent antioxidants in various lipid-containing systems. The study investigated these phenolic antioxidants using different fractions of canola and mustard seeds. Phenolic compounds were extracted from whole seeds and their fractions: hulls and cotyledons, using 70% methanol ...

BACKGROUND Buckwheat flour and buckwheat sprouts possess antioxidant properties, and previous studies have reported on buckwheat flour displaying an inhibitory activity for angiotensin-I converting enzyme (ACE). Information is lacking on the bioactivity of other parts of the buckwheat, such as the seed hulls and plant stalks. This study investigates the ACE inhibitory activity and antioxidant a...

We investigate two di erent notions of \size" which appear naturally in Statistical Learning Theory. We present quantitative estimates on the fat-shattering dimension and on the covering numbers of convex hulls of sets of functions, given the necessary data on the original sets. The proofs we present are relatively simple since they do not require extensive background in convex geometry.

Previous studies showed that Near Infrared Spectroscopy (NIRS) could distinguish between Roundup Ready® (RR) and conventional soybeans at the bulk and single seed sample level, but it was not clear which compounds drove the classification. In this research the varieties used did not show significant differences in major compounds between RR and conventional beans, but moisture content had a big...

This paper collects together a miscellany of results originally motivated by the analysis of the generalization performance of the “maximum-margin” algorithm due to Vapnik and others. The key feature of the paper is its operator-theoretic viewpoint. New bounds on covering numbers for classes related to Maximum Margin classes are derived directly without making use of a combinatorial dimension s...
