Background: Non-infection caused urticaria is a common ailment in adolescents. Its symptoms (e.g., unusual rash appearance, limitation of daily activities, and recurrent itching) may contribute to the development of depressive stress in adolescents; the potential link has not been well studied. This study aimed to investigate the risk of major depression after a first-attack and non-infection caused urticaria. Methods: This study used the Taiwan Longitudinal Health Insurance Database. A total of 5,755 adolescents hospitalized for a first-attack and non-infection caused urticaria from 2005 to 2009 were recruited as the study group, together with 17,265 matched non-urticarial enrollees who comprised the control group. Patients who had any history of urticaria or depression prior to the evaluation period were excluded. Each patient was followed for one year to identify the occurrence of depression. Cox proportional hazards models were generated to compute the risk of major depression, adjusting for the subjects\' sociodemographic characteristics. Depression-free survival curves were also analyzed. Results: Thirty-four (0.6%) adolescents with non-infection caused urticaria and 59 (0.3%) non-urticarial control subjects suffered a new-onset episode of major depression during the study period. The stratified Cox proportional analysis showed that the crude hazard ratio (HR) of depression among adolescents with urticaria was 1.73 times (95% CI, 1.13-2.64) than that of the control subjects without urticaria. Moreover, the HR were higher in physical (HR: 3.39, 95% CI 2.77-11.52) and allergy chronic urticaria (HR: 2.43, 95% CI 3.18-9.78). Conclusion: Individuals who have a non-infection caused urticaria during adolescence are at a higher risk of developing major depression.

本發明係揭露一種用於全像儲存之影像定位方法，其係利用一參考灰階框，在接收到之灰階影像上依序擷取與灰階框大小相同之區域影像，作為一擷取影像，且將參考灰階框與每一擷取影像進行區域比對，以得到複數數值，進而藉此建立一二維原矩陣。再來令小於零之數值為零，以轉換二維原矩陣為一二維矩陣。利用維度大小與參考灰階框小於或等於之一擷取矩陣及二維矩陣，取得一定位矩陣，並據此於二維矩陣之中心區域找到最大之數值，作為一定位值。最後，利用定位值找到其對應於灰階影像上之位置，作為定位點位置，以藉此還原扭曲或失焦之灰階影像。

「傳播基礎寫作」應該如何教？這是全球傳播與新聞相關學系，甚至擴及管理、語言領域，不斷思索、但仍無解答的議題。傳播基礎寫作的課程結構，應該如何規劃？課程形式為何？什麼是適當的教材？作業是否為不斷的寫作與檢討，而不考慮其他方式？進一步，授課教師除研究專長符合外，本身是否要有豐富經驗？部分媒體認為，由目前第一線的專家教學，成效會更好，是否合理？

「何謂文化的生命力」，是每次在討論傳播與科技學系學生培養、課程規劃及系所發展時，皆會碰到的議題，面對耳熟能詳的文化復興、承先啟後等，我心中的答案總是「創新」兩個字。尤其在大學，我們樂於面對未知、提出未來的各種可能，並勇於付諸實現，期待我們也能創造出Yahoo、Google或臉書，能影響全世界。簡言之，文化要創新，不是復興。我們重視的是不同的想法，而非千篇一律。

In this paper, a novel light separator with contrast ratio enhancement but maintaining the optical efficiency of the DLP projection system is proposed. The main capability of the novel light separator is to direct the uncontrolled light away from the image system. The working theorem for the novel light separator is derived as well. Uncontrolled light is kept away from the image system by a total internal reflection surface, thereby effectively improving the image quality. Compared with the conventional contrast ratio enhancement method, the FO:FO contrast ratio can be improved from 839: 1 to 48250: 1, the ANSI contrast ratio can be improved from 180: 1 to 306: 1, while the image system efficiency remains at 76.2%.

We study the quantum phases and phase transitions of the Kane-Mele Hubbard (KMH) model on a zigzag ribbon of honeycomb lattice at a finite size via the weak-coupling renormalization group (RG) approach. In the noninteracting limit, the Kane-Mele (KM) model is known to support topological edge states where electrons show helical property with orientations of the spin and momentum being locked. The effective interedge hopping terms are generated due to finite-size effect. In the presence of an on-site Coulomb (Hubbard) interaction and the interedge hoppings, special focus is put on the stability of the topological edge states (TI phase) in the KMH model against (i) the charge and spin gaped (II) phase, (ii) the charge gaped but spin gapless (IC) phase, and (iii) the spin gaped but charge gapless (CI) phase depending on the number (even/odd) of the zigzag ribbons, doping level (electron filling factor) and the ratio of the Coulomb interaction to the interedge tunneling. We discuss different phase diagrams for even and odd numbers of zigzag ribbons. We find the TI-CI, II-IC, and II-CI quantum phase transitions are of the Kosterlitz-Thouless (KT) type. By computing various correlation functions, we further analyze the nature and leading instabilities of these phases. The relevance of our results for graphene is discussed.

Background: Estradiol plays an important role in the regulation of collagen metabolism. Deficiency of estradiol has been reported to be associated with the degeneration of many connective tissues. However, the association of estradiol and hypertrophy of the ligamentum flavum was seldom explored. Therefore, we studied the effects of estradiol on cultured cells from the ligamentum flavum. Methods: Primary cultures of human ligamentum flavum cells obtained from surgical specimens of 14 patients undergoing spinal surgery were used to investigate the effect of estradiol on cell proliferation and the expression of collagen, elastin, and matrix metalloproteinases. Downstream pathways of estrogen receptor underlying the regulation of metalloproteinases were also investigated. Results: In our study, we revealed the existence of estrogen receptors on both female and male ligamentum flavum cells with a gender difference. 17 beta-estradiol increased early (24 hours) proliferation of ligamentum flavum cells in a dose dependent manner and the effect could not be seen when the cell density increased. Estradiol with a concentration of 10-9 M decreased collagen levels and increased the expression of MMP-13. Adding an antagonist of PI3K downstream pathway could reverse the expression of MMP-13 caused by estradiol. Conclusions: The results implied estradiol regulated the expression of MMP-13 via PI3K pathway and contributed to the homeostasis of extracellular matrix in the ligamentum flavum.

Ma and Wang derived an equation linking the separation location and times for the boundary layer separation of incompressible fluid flows. The equation gave a necessary condition for the separation (bifurcation) point. The purpose of this paper is to generalize the equation to other geometries, and to phrase it as a simple ODE. Moreover we consider the Navier-Stokes equation with the Coriolis effect, which is related to the presence of trade winds on Earth. (C) 2014 Elsevier B.V. All rights reserved.

We experimentally demonstrate the use of annular beams to improve lateral resolution in laser-diode-based pump-probe microscopy. We found that the width of the point-spreading function in the case of the annular pump-probe beams is 162 nm, which is 30% smaller than that of the circular beams (232 nm). Furthermore, side lobes were efficiently suppressed at the focal plane since the pump-probe signal is proportional to the product of the two beam intensities. This scheme is demonstrated for the photothermal signal of nonfluorescent gold nanoparticles and the stimulated emission signal of fluorescence beads. (C) 2014 Optical Society of America
