- Description:
- Sometimes intraorbital foreign bodies lead to unexpected findings. A 16-year old boy was referred due to ocular surface trauma. A conjunctival laceration was detected at the level of the left caruncle with associated left exotropia, reduced adduction as well as a preretinal hemorrhage along the nasal periphery of the fundus. A blow-out fracture of the medial orbital wall was suspected and a CT scan of the orbits was scheduled which revealed the presence of a large intraorbital foreign body. The removal of the intraorbital foreign body (which proved to be a bullet) and precautionary laser photocoagulation along the nasal periphery of the left eye were performed. Ocular surface trauma may reveal unexpected findings, such as an intraorbital foreign body, requiring investigation by a CT scan., Efstathios T. Detorakis, Emmanouil K.

- Description:
- This report describes a case of male patient with metastatic papillary carcinoma of unknown primary origin with unusual high levels of CA 125. Laboratory tests in serum and plasma (urea, creatinine, uric acid, sodium, potassium, total bilirubin, ALT, AST, GMT, ALP, C-reactive protein, and glucose) were normal except C-reactive protein (57.6 mg/l). Computer tomography scan showed tumorous formations situated in the area of both kidneys. According to the literature we performed more detailed laboratory investigation (CEA, CA 125, CA 15-3, CA 19-9, AFP) and we found only serum level of CA 125 significantly elevated (> 600 kU/l). The results of recent studies suggest that CA 125 might be useful as a serum tumor marker also in patients with other carcinomas apart ovarian cancer., Kazuistika popisuje případ pacienta s metastatickým papilárním karcinomem z neznámého zdroje s neobvykle vysokou hodnotou CA 125. Analyty stanovené v séru a plasmě (urea, kreatinin, kyselina močová, sodný kation, draselný kation, celkový bilirubin, ALT, AST, GMT, ALP, C-reaktivní protein a glukóza) byly v referenčním rozmezí kromě C-reaktivního proteinu (57,6 mg/l). Pomocí počítačové tomografie byly prokázány tumorózní útvary v oblasti obou ledvin. V souladu s literaturou bylo provedeno podrobnější laboratorní vyšetření (CEA, CA 125, CA 15-3, CA 19-9, AFP), kde byla prokázána významně zvýšená hladina CA 125 (> 600 kU/l). Výsledky některých studií poukazují na to, že CA 125 by mohl být vhodným nádorovým markerem také u pacientů s jinými druhy karcinomů než s karcinomem ovaria., Eva Klapková, Richard Průša, J.

- Description:
- Cílem této recenze je shrnout hlavní aspekty knihy autora Neala C. Hogana Unhealed wounds: medical malpractice in the twentieth century, která vyšla v roce 2003 v New Yorku. Jak název napovídá, kniha se zabývá chronologickým vývojem problematiky profesního pochybení lékařů v USA v minulém století. Tato recenze stručně informuje o autorovi, nicméně její podstatná část se zabývá obsahem publikace. Recenze se zabývá popisem jednotlivých kapitol ve stejném pořadí, jak jsou uvedeny v knize. Zdůrazněny jsou hlavní historické milníky problematiky profesního pochybení lékařů. V závěru je recenzentem provedeno zhodnocení publikace a zamyšlení nad případnou aplikací americké právní doktríny týkající se profesního pochybení lékaře v českém právním systému., The aim of this review is to summarize main aspects of the book Unhealed wounds: medical malpractice in the twentieth century written by Neal C. Hogan, published in 2003 in New York. As the title suggests the book itself is focused on chronological development of medical malpractice in the USA in previous century. This review briefly informs about the author but it´s mainly concentrated on the publication´s content. Paper itself descripts component chapters in the same order as it is written in the book. Break points of malpractice history are highlighted. In conclusion of the review author evaluates the book and presents his own reflection about application of the American legal doctrine of medical malpractice in the Czech legal system., and Jan Kotula

16435. Unicyclic graphs with bicyclic inverses
- Creator:
- Panda, Swarup Kumar
- Format:
- print, bez média, and svazek
- Type:
- model:article and TEXT
- Subject:
- matematika, mathematics, adjacency matrix, unicyclic graph, bicyclic graph, inverse graph, perfect matching, 13, and 51
- Language:
- English
- Description:
- A graph is nonsingular if its adjacency matrix $A(G)$ is nonsingular. The inverse of a nonsingular graph $G$ is a graph whose adjacency matrix is similar to $A(G)^{-1}$ via a particular type of similarity. Let $\mathcal{H}$ denote the class of connected bipartite graphs with unique perfect matchings. Tifenbach and Kirkland (2009) characterized the unicyclic graphs in $\mathcal{H}$ which possess unicyclic inverses. We present a characterization of unicyclic graphs in $\mathcal{H}$ which possess bicyclic inverses., Swarup Kumar Panda., and Obsahuje bibliografii

16436. Uniform a priori estimates for discrete solution of nonlinear tensor diffusion equation in image processing
- Creator:

- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- funite volume method, diamond-cell method, image processing, nonlinear parabolic equation, and tensor diffusion
- Language:
- English
- Description:
- This paper concerns with the finite volume scheme for nonlinear tensor diffusion in image processing. First we provide some basic information on this type of diffusion including a construction of its diffusion tensor. Then we derive a semi-implicit scheme with the help of so-called diamond-cell method (see \cite{Coirier1} and \cite{Coirier2}). Further, we prove existence and uniqueness of a discrete solution given by our scheme. The proof is based on a gradient bound in the tangential direction by a gradient in normal direction. Moreover, the proofs of L2(Ω) - a priori estimates for our discrete solution are given. Finally we present our computational results.

16437. Uniform controllability for the beam equation with vanishing structural damping
- Creator:
- Bugariu, Ioan Florin
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- beam equation, null-controllability, structural damping, moment problem, and biorthogonals
- Language:
- English
- Description:
- This paper is devoted to studying the effects of a vanishing structural damping on the controllability properties of the one dimensional linear beam equation. The vanishing term depends on a small parameter $\varepsilon \in (0,1)$. We study the boundary controllability properties of this perturbed equation and the behavior of its boundary controls $v_{\varepsilon }$ as $\varepsilon $ goes to zero. It is shown that for any time $T$ sufficiently large but independent of $\varepsilon $ and for each initial data in a suitable space there exists a uniformly bounded family of controls $(v_\varepsilon )_\varepsilon $ in $L^2(0, T)$ acting on the extremity $x = \pi $. Any weak limit of this family is a control for the beam equation. This analysis is based on Fourier expansion and explicit construction and evaluation of biorthogonal sequences. This method allows us to measure the magnitude of the control needed for each eigenfrequency and to show their uniform boundedness when the structural damping tends to zero.

16438. Uniform convergence of double trigonometric series
- Creator:
- Kórus, Péter
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- sine series, cosine series, double sine series, sine-cosine series, double cosine series, uniform convergence, regular convergence, general monotone sequence, general monotone double sequence, and supremum bounded variation
- Language:
- English
- Description:
- It is a classical problem in Fourier analysis to give conditions for a single sine or cosine series to be uniformly convergent. Several authors gave conditions for this problem supposing that the coefficients are monotone, non-negative or more recently, general monotone. There are also results for the regular convergence of double sine series to be uniform in case the coefficients are monotone or general monotone double sequences. In this paper we give new sufficient conditions for the uniformity of the regular convergence of sine-cosine and double cosine series, which are necessary as well in case the coefficients are non-negative. The new results also bring necessary and sufficient conditions for the uniform regular convergence of double trigonometric series in complex form.

- Abdullayev, F. G.
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- conformal mapping, Quasiconformal curve, Bieberbach polynomials, and complex approximation
- Language:
- English
- Description:
- Let $C$ be the extended complex plane; $G\subset C$ a finite Jordan with $ 0\in G$; $w=\varphi (z)$ the conformal mapping of $G$ onto the disk $ B\left( {0;\rho _{0}}\right):={\left\rbrace {w\:{\left| {w}\right| }<\rho _{0}} \right\lbrace }$ normalized by $\varphi (0)=0$ and ${\varphi }^{\prime }(0)=1$. Let us set $\varphi _{p}(z):=\int _{0}^{z}{{\left[ {{\varphi } ^{\prime }(\zeta )}\right] }^{{2}/{p}}}\mathrm{d}\zeta $, and let $\pi _{n,p}(z)$ be the generalized Bieberbach polynomial of degree $n$ for the pair $(G,0)$, which minimizes the integral $ \iint \limits _{G}{{\left| {{\varphi }_{p}^{\prime }(z)-{P}_{n}^{\prime }(z)}\right| }}^{p}\mathrm{d}\sigma _{z}$ in the class of all polynomials of degree not exceeding $\le n$ with $P_{n}(0)=0$, ${P}_{n}^{\prime }(0)=1$. In this paper we study the uniform convergence of the generalized Bieberbach polynomials $\pi _{n,p}(z)$ to $\varphi _{p}(z)$ on $\overline{G}$ with interior and exterior zero angles and determine its dependence on the properties of boundary arcs and the degree of their tangency.
