A 71-yr-old man presented to our emergency department, with 12 hr of chest pain and dyspnea. A computed tomography scan demonstrated the presence of a 7.4 cm ascending aortic aneurysm, type A aortic dissection, in the distal ascending aorta extending into brachiocephalic and right common carotid arteries. A transthoracic echocardiogram showed type A dissection, with intimal flap prolapsing thro...

Cities experience elevated temperature, CO2 , and nitrogen deposition decades ahead of the global average, such that biological response to urbanization may predict response to future climate change. This hypothesis remains untested due to a lack of complementary urban and long-term observations. Here, we examine the response of an herbivore, the scale insect Melanaspis tenebricosa, to temperat...

AbstRAct Domain Name System (DNS) is the system for the mapping between easily memorizable host names and their IP addresses. Due to its criticality, the Internet Engineering Task Force (IETF) has defined a DNS Security Extension (DNSSEC) to provide data-origin authentication. In this paper, we point out two drawbacks of the DNSSEC standard in its handling of DNS dynamic updates: 1) the on-line...

and Applied Analysis 3 function. Since the edge detector function g : g u0 : 1/ 1 |∇ u0 ∗Gσ x | with Gσ x 1/2πσ2 exp − x2/2σ2 can depict the information of edges, we can employ it as a balance function; that is, we can apply the following model: min u β 2 ‖u − u0‖L2 ∣ ∣1 − gu∣∣BV ∣ ∣gu ∣ ∣ BV 2 1.7 to restore the noisy image 16 . Obviously, | 1 − g u|BV tends to be predominant where edges most ...

We find that the prostate cancer cell lines ALVA-31, PC-3, and DU 145 are highly sensitive to apoptosis induced by TRAIL (tumor-necrosis factor-related apoptosis-inducing ligand), while the cell lines TSU-Pr1 and JCA-1 are moderately sensitive, and the LNCaP cell line is resistant. LNCaP cells lack active lipid phosphatase PTEN, a negative regulator of the phosphatidylinositol (PI) 3-kinase/Akt...

For building applications, woven fabrics have been widely used as finishing elements of room interior but not in particular aimed for sound absorbers. Considering the micro perforation fabrics, they should potential to be micro-perforated panel (MPP) absorbers; some measurement results indicated such absorption ability. Hence, it is importance a model enable us predicting their characteristic t...
