ARNAB: Transparent Service Continuity across Orchestrated Edge Networks

Paper presented at: IEEE GLOBECOM 2018 Workshops: Intelligent Network orchestration and interaction in 5G and beyond. Abu Dabhi. 9-13 December 2018In this paper, we present an architecture for transparent service continuity for cloud-enabled WiFi networks called ARNAB: ARchitecture for traNsparent service continuity viA douBle-tier migration. The term arnab means rabbit in Arabic. It is dubbed for the proposed service architecture because a mobileuser service with ARNAB behaves like a rabbit hopping through the WiFi infrastructure. To deliver continuous services, deploying edge clouds is not sufficient. Users may travel far from the initial serving edge and also perform multiple WiFi handoffs during mobility. To solve this, ARNAB employs a double-tier migration scheme. One migration tier is for user connectivity, and the other one is for edge applications. Our experimental results show that ARNAB can not only enable continuous service delivery but also outperform the existing work in the area of container live migration across edge clouds.This work has been partially supported by the H2020 collaborative Europe/Taiwan research project 5G-CORAL (grant num. 761586)

Enabling Mobile Service Continuity across Orchestrated Edge Networks

Edge networking has become an important technology for providing low-latency services to end users. However, deploying an edge network does not guarantee continuous service for mobile users. Mobility can cause frequent interruptions and network delays as users leave the initial serving edge. In this paper, we propose a solution to provide transparent service continuity for mobile users in large-scale WiFi networks. The contribution of this work has three parts. First, we propose ARNAB architecture to achieve mobile service continuity. The term ARNAB means rabbit in Arabic, which represents an Architecture for Transparent Service Continuity via Double-tier Migration. The first tier migrates user connectivity, while the second tier migrates user containerized applications. ARNAB provides mobile services just like rabbits hop through the WiFi infrastructure. Second, we identify the root-causes for prolonged container migration downtime. Finally, we enhance the container migration scheme by improving system response time. Our experimental results show that the downtime of ARNAB container migration solution is 50% shorter than that of the state-of-the-art migration.This work has been partially funded by the H2020 Europe/Taiwan joint action 5G-DIVE (Grant #859881) and also partially funded by the Ministry of Science and Technology, under the Grant Number MOST 108-2634-F-009-006 - through Pervasive Artificial Intelligence Research (PAIR) Labs, Taiwan

The Quality Improvement of Solid-State Fermentation with Cordyceps militaris by UVB Irradiation

Cordyceps militaris, ljekovita i jestiva gljiva, korištena je za fermentaciju na čvrstoj podlozi od heljde i prirodne riže. Svrha je istraživanja bila ispitati utjecaj ultraljubičastih B (UVB) zraka na udjele vitamina D2 i biološki aktivnih tvari te antioksidacijska svojstva heljde i prirodne riže tijekom fermentacije na čvrstoj podlozi s pomoću C. militaris. Ozračeni uzorci fermentirane heljde i prirodne riže imali su znatno veći udjel vitamina D2, i to od 0-0.3 do 1.18-16.79 μg/g, dok je u svježoj prirodnoj riži udjel vitamina D2 nakon fermentacije bio 16.79 μg/g. Udjeli adenozina, kordicepina i polisaharida u ozračenim sušenim uzorcima fermentiranim s pomoću C. militaris bili su od 0.08 do 11.5 mg/g, odnosno veći nego u svježim uzorcima fermentiranim s pomoću C. militaris (0.07–8.40 mg/g). Uzorci fermentirani s pomoću C. militaris imali su manje vrijednosti EC50 i veći udjel antioksidansa od nefermentiranih uzoraka. Nakon fermentacije na čvrstoj podlozi i zračenja UVB svjetlom, smanjili su se udjeli biološki aktivnih i antioksidacijskih sastojaka te antioksidacijska svojstva uzorka. No, usprkos tome, količina navedenih komponenata bila je dostatna.Cordyceps militaris, a medicinal and edible mushroom, was used to ferment buckwheat and embryo rice by solid-state fermentation (SSF). Our aim was to investigate the effect of ultraviolet B (UVB) light irradiation on the content of vitamin D2 and biologically effective components, and antioxidant properties of buckwheat and embryo rice in SSF with C. militaris. Irradiated samples of buckwheat and embryo rice fermented by C. militaris had significantly increased vitamin D2 content, from 0-0.3 to 1.18-16.79 μg/g, while the increase in fresh embryo rice fermented by C. militaris was up to 16.79 μg/g. The content of adenosine, cordycepin and polysaccharide in irradiated dry samples fermented by C. militaris was 0.08 to 11.15 mg/g, higher than that of the irradiated fresh samples fermented by C. militaris (0.07–8.40 mg/g). Samples fermented by C. militaris had lower EC50 values and higher content of antioxidants than did unfermented samples. When the solid-state fermented sample was irradiated with UVB light, the content of biologically effective and antioxidant components and antioxidant property of sample decreased. However, it still contained enough of these biologically effective and antioxidant components

Aspartate β-Hydroxylase Expression Promotes a Malignant Pancreatic Cellular Phenotype

Pancreatic cancer (PC) is one of the leading causes of cancer related deaths due to aggressive progression and metastatic spread. Aspartate β-hydroxylase (ASPH), a cell surface protein that catalyzes the hydroxylation of epidermal growth factor (EGF)-like repeats in Notch receptors and ligands, is highly overexpressed in PC. ASPH upregulation confers a malignant phenotype characterized by enhanced cell proliferation, migration, invasion and colony formation in vitro as well as PC tumor growth in vivo. The transforming properties of ASPH depend on enzymatic activity. ASPH links PC growth factor signaling cascades to Notch activation. A small molecule inhibitor of β-hydroxylase activity was developed and found to reduce PC growth by downregulating the Notch signaling pathway. These findings demonstrate the critical involvement of ASPH in PC growth and progression, provide new insight into the molecular mechanisms leading to tumor development and growth and have important therapeutic implications

An overview of Old Tibetan synchronic phonology

Despite the importance of Old Tibetan in the Tibeto-Burman language family, little research has treated Old Tibetan synchronic phonology. This article gives a complete overview of the Old Tibetan phonemic system by associating sound values with the letters of the Tibetan alphabet and exploring the distribution of these sounds in syllable structure
