We describe degenerations and smoothings of linear series on some reducible algebraic curves. Applications include a proof that the moduli space of curves of genus g has general type for all g > 24, a proof that the monodromy action is transitive on the set of linear series of dimension r and degree d on a general curve of genus g when p := g — (r + l)(g — d+r) = 0, a proof that there exist Wei...

conclusions although in our study washout pattern was the most powerful indicator for malignant pathology in non mass like enhancing lesions, more studies with larger sample size needs in this regard. background several studies on the diagnostic efficacy of mri has not real consensus for the accuracy of mri characteristics in non mass like breast lesions, and the number of malignant lesions in ...

in this study, to know about the phylogeny of escherichia coli isolated from broilers with collibacillosis in tabriz, 70 e. coli isolates recovered from broilers with collibacillosis were characterized for phylogenetic group (a, b1, b2, d) by multiplex pcr. of the all 70 samples, 35 (50%) isolates were classified as type a, 32 (45%) as type d, 2 (2.8%) as type b1 and 1 (2.8%) as type b2. thi...

The classical Hurwitz numbers which count coverings of a complex curve have an analog when the curve is endowed with a theta characteristic. These “spin Hurwitz numbers”, recently studied by Eskin, Okounkov and Pandharipande, are interesting in their own right. By the authors’ previous work, they are also related to the Gromov-Witten invariants of Kähler surfaces. We prove a recursive formula f...

BACKGROUND AND PURPOSE Salivary duct carcinoma (SDC) is regarded as a high-grade malignancy in the current classification of salivary gland neoplasms. The aim of our study was to describe the MR imaging features of SDC. METHODS Nine patients with SDC underwent MR imaging study. The apparent diffusion coefficient (ADC) values of SDCs were measured from diffusion-weighted images. Time-signal in...

Quantum curves were introduced in the physics literature. We develop a mathematical framework for case associated with Hitchin spectral curves. In this context, quantum curve is Rees $\mathcal{D}$-module on smooth projective algebraic curve, whose semi-classical limit produces of Higgs bundle. give method quantization by concretely constructing one-parameter deformation families opers. We pro...

this study was carried out to investigate the relationship between early lactation curve parameters andcalving interval in holstein cows of iran. in order to describe the lactation curve, the incomplete gammafunction was fitted to 5,754,428 test-day milk records corresponding to 766,108 lactations on 315,634 cowsin 2,448 herds. cows with higher milk yield during early lactation had shorter calv...

We give two proofs that the 3–torus is not weakly d–congruent to #S × S, if d > 2. We study how cohomology ring structure relates to weak congruence. We give an example of three 3–manifolds which are weakly 5–congruent but are not 5–congruent. Let d be an integer greater than one. In [G], we considered two equivalence relations generated by restricted surgeries on oriented closed 3–manifolds. W...
