Sažetak Karcinom dojke najčešći je oblik karcinoma kod žena. Rana detekcija i dijagnoza karcinoma dojke omogućene mamografskim pregledima omogućuju pravovremeno liječenje i povećavaju mogućnosti potpunog izlječenja. Kako bi se radiolozima pomoglo u donošenju ispravne i pravovremene dijagnoze razvijaju se računalni programi koji analiziraju mamografske slike te detektiraju promjene u dojkama. Je...

Kontekst ima pomembno vlogo pri splošnem zaznavanju prizorov, saj zagotavlja dodatno informacijo o možnih lokacijah objektov v slikah. Detektorji objektov, ki se uporabljajo v računalnǐskem vidu, tovrstne informacijo običajno ne izkoristijo. V članku bomo zato predstavili koncept, kako se lahko kontekstualne informacije naučimo iz primerov slik prizorov. To informacijo bomo uporabili za izračun...

Least mean square (LMS) type adaptive algorithms have attracted much attention due to their low computational complexity. In the scenarios of sparse channel estimation, zero-attracting LMS (ZA-LMS), reweighted ZA-LMS (RZA-LMS) and reweighted -norm LMS (RL1-LMS) have been proposed to exploit channel sparsity. However, these proposed algorithms may hard to make tradeoff between convergence speed ...

BACKGROUND Modic changes (MC) are associated with low back pain (LBP), but effective treatments are lacking. The aim of this randomized, placebo-controlled, double-blinded trial was to evaluate the efficacy of zoledronic acid (ZA) for chronic LBP among patients with MC in magnetic resonance imaging (MRI). METHODS Inclusion criteria were LBP lasting ≥3 months, with an intensity of ≥6 on a 10-c...

Multilingual dependency parsing is gaining popularity in recent years for several reasons. Dependency structures are more adequate for languages with freer word order than the traditional constituency notion. There is a growing availability of dependency treebanks for new languages. Broad coverage statistical dependency parsers are available and easily portable to new languages. Dependency pars...

Significant progress has been made in the past four years in South Africa in the field of animal power and an awareness of the use, importance and necessity of using cattle (bovine) and donkeys, horses and mules (equine) for draught purposes has been achieved at all levels. However challenges still exist, and these are explored in order to determine specific and appropriate strategies to progre...

Each symmetric matrix A over C defines a graph homomorphism function ZA(·) on undirected graphs. The function ZA(·) is also called the partition function from statistical physics, and can encode many interesting graph properties, including counting vertex covers and k-colorings. We study the computational complexity of ZA(·) for arbitrary symmetric matrices A with algebraic complex values. Buil...
