We introduce the finite ring S2m = Z2m + iZ2m . We develop a theory of self-dual codes over this ring and relate self-dual codes over this ring to complex unimodular lattices. We describe a theory of shadows for these codes and lattices. We construct a gray map from this ring to the ring Z2m and relate codes over these rings, giving special attention to the case when m = 2. We construct various...

in this study, the vertical, transverse and oblique diameters of the spinal cord segments (c1, c6, c12, c18, t1, t4, l1, l4, l6 and l8) and the ratio of gray matter to white matter in chick (l month) and adult (18 months) male ostriches, each group consisted of 3 animals, were measured with standard micrometric method using 6 μm thick sections by light microscope. with advancement of age, the r...

decline in postharvest losses of kiwifruit depended to maintain of quality characteristics during storage and transportation. storage losses caused serious economic losses in kiwifruit. this study was conducted to inhibition of pathogen infection and increasing fruit quality of kiwifruit. hayward kiwifruits inoculated by b.cinerea conidia through pore wounds which formed by removal of the pedic...

Abstract To solve the problem of ergonomic evaluation suit production system, a hybrid method IAHP and gray entropy theory is proposed. Firstly, literature reviews for ergonomics tools techniques are introduced. Furthermore, index system operation established according to practice. Besides, comprehensive models process Finally, detailed sewing, ironing clipping introduced by an example, results...

CLINICAL PRESENTATION A 16 year old girl was referred to dermatology clinic with bilateral blue gray hyperpigmented patches on her cheeks since birth. Upon close physical examination, scleral blue-gray hyperpigmentation was observed in both her eyes (Figure 1). She also had a blanchable red patch with poorly defined borders on her right cheek (Figure 2). Ophthalmology consultation further revea...

Abstract Aiming at the problems of image edge blur and detail loss in most denoising models, an model based on improved fractional calculus is proposed. Through classification noise, integer order PDE discussed. Based mathematical theory calculus, The by combining texture detection operator, gray value smoothing factor fast algorithm. simulation experiment carried out MATLAB platform. results s...

Contemporary motivational theories of psychopathy (Lykken, 1995) employ constructs from Gray's Reinforcement Sensitivity Theory (RST; Gray, 1982), behavioral inhibition system (BIS) and behavioral activation system (BAS) functioning, to explain etiologic differences in psychopathy subtypes. Carver and White's (1994) BIS/BAS scales are the most widely used measures of these constructs, yet there...

Dedifferentiation, or decreased processing specificity, has been suggested to represent a ubiquitous characteristic of cognitive aging. In this study, we examined both age-related differences and intra-group differences in neural specificity in the ventral visual cortex for color, words, faces and places. Our results demonstrated that neural dedifferentiation was not ubiquitous across stimulus ...

In this paper, the capacity of the BICM system over AWGN channels is first analyzed; the curves of BICM capacity versus SNR are also got by the Monte-Carlo simulations, and compared with the curves of the CM capacity. Based on the analysis results, we simulate the error performances of BICM system with LDPC codes. Simulation results show that the capacity of BICM system with LDPC codes is enorm...
