Segmenting the vertebrae is an important part of diagnosing spine diseases and planning surgery. The vertebra's complex anatomy, featuring similar shapes neighboring bones vague boundaries, presents substantial challenges for precise semantic segmentation. Traditional methods often depend heavily on local features, making it difficult to capture global context resulting in less accurate recognition. Consequently, automated efficient segmentation approaches are crucial overcoming these...
Bananas (Musa spp.) are among the top-produced food crops, serving as a primary source of for millions people. Cultivated bananas originated primarily from wild diploid species Musa acuminata (A genome) and balbisiana (B through intra- interspecific hybridization selections via somatic variation. Following publication complete A- B-genome sequences, prospects complementary studies on S- T-genome traits, key gene identification yield, ripening, quality, stress resistance, advances in...
This paper treats channel estimation in multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems with correlation at the receive antenna array. A two-step algorithm is proposed. Firstly, iterative quadrature maximum likelihood based time delay and spatial signature presented by utilizing special training signals a cyclic structure. The matrix of vector valued impulse response formulated as function signature, delay, pulse shaping filter. joint...
Compared with the Fourier analysis, fractional analysis is more suitable to process linear frequency modulation type non-stationary functions. To best of our knowledge, theoretical framework has not well established yet, especially for series (FrFS) and discrete transform (DFrFT) algorithms. tackle these problems, efficient FrFS DFrFT algorithms based on Möbius function are proposed. First, existence applicability analyzed basing inversion formula. Second, two kinds fast infinite/finite...

Cramer-Rao lower bound (CRLB) on estimates is provided. performance illustrated based computer simulation. It shows that proposed efficient estimator which able achieve CRLB
Infection with Epstein-Barr virus (EBV) may be correlated to the onset of acute leukemia (AL). Studies were performed investigate relationship between EBV infection and immunophenotyping lymphoblastic (ALL) chromosome aberrations. Additionally, effects on clinical prognosis described. Fluorescence quantitative polymerase chain reaction (FQ-PCR) was used detect EBV-DNA copy numbers from bone marrow in 110 cases patients ALL, 75 myeloid (AML), 37 hematologically healthy control subjects....
The chirp-cyclostationary (CCS) process is the generalized form of cyclostationary (CS) and it can describe nonstationary stochastic signal models more exactly in practical applications. Basically, statistics CCS signals have been defined studied based on correlation function. However, when measurement chosen as above statistics, output a linear-variant filter zero-power for any input pure signal. This barrier to further analyze properties filters by second-order statistics. In this paper,...
