Air network performance and hub competitive position : evaluation of primary airports in East and South-East Asia

The growth of hub-and-spoke operations has changed the structure of competition among airlines and airports, meaning that airlines now compete both directly (air services from A to B) as well as indirectly (services from A to B via H). Traditional measures of airport performance, such as passenger enplanements and aircraft movements, fail to address indirect connectivity via hubs. This paper uses the NetScan connectivity model to compare the competitive position of 13 primary airports in East and South-East Asia between 2001 and 2007. The results reveal that Tokyo-Narita has the greatest total connectivity, and that it is composed of direct and indirect connections via other hubs. It also has the greatest hub connectivity. However, the most striking connectivity growth took place at the three major airports in mainland China: Beijing, Shanghai and Guangzhou. The number of both direct and indirect connections at these three airports increased at a much higher rate than at other airports in the sample. Indeed, other airports, such as Osaka-Kansai and Taipei, experienced deteriorating network performance during the period of analysis. The results presented here may be helpful for airlines and airports in identifying their competitive position vis-a-vis other airlines and airports.
Optimal attack strategy with heterogeneous costs in complex networks

The problem of network disintegration, such as suppressing the epidemic spreading and destabilizing terrorist networks, has broad applications and recently has received growing attention. We first presents a cost constrain model for attack strategy in complex networks, in which the attack cost for a node is heterogeneous. Then we introduce the unequal probability sampling into the network disintegration problem and present an optimization model for optimal attack strategy with limited attack costs in complex networks. We investigate the influence of cost-sensitive parameter and cost-constraint parameter on the optimal attack strategy in both model networks and real-world networks. We find that the low-degree nodes are attacked preferentially when the cost constraint is tight; however, the high-degree nodes are attacked preferentially when the cost constraint is relax. Moreover, we find there is a threshold for the cost-sensitive parameter, the high-degree nodes won't be attacked preferentially if the cost of single node is more than a threshold.
A Uniform and Universal Accounting and Currency System and its Influence on Corporate Value

This study analyzes the effects of the introduction of the Euro on the corporate market values of the Fortune Global 500 (FG500) companies over the period 1990 to 2007. Our results demonstrate a positive impact of the single Euro currency on the market values of the FG500 companies domiciled in that region. These valuation effects are realized through a number of channels, including the reduction of capital costs, increase in intra-European trade and real GDP growth. In the light of these advantages, we argue that both, a single global accounting standard a single global currency are necessary for welfare optimizing investment decisions and conclude that the introduction of a single global currency is not a question of 'whether' but 'when'.
To What Extent Can Arm–Hand Skill Performance—of Both Healthy Adults and Children—Be Recorded Reliably Using Multiple Bodily Worn Sensor Devices?

Neurological patients often encounter arm-hand problems in daily life. Bodily worn sensors may be used to assess actual performance by quantifying specific movement patterns associated with specific activities. However, signal reliability during activities of daily living should be determined first. The aim is to determine to what extent standardized arm-hand skill performance of both healthy adults and healthy children can be recorded reliably using a combination of multiple sensor devices. Thirty adults and thirty-two children (aged between 6-18 years) performed the activities drinking, eating and combing five times in a standardized setting. Sensor devices, each containing a triaxial accelerometer, gyroscope and magnetometer were attached to the arms, hands and trunk of the participants. Within-subject and between-subject reliability of the signal patterns amongst skill repetitions was determined by calculating Intraclass Correlation Coefficients (ICCs). Median reliability was good to very good for all activities performed (both within and between subjects). Regarding within-subject reliability (instruction-condition), median ICCs ranged between 0.76-0.90 and 0.68-0.92 for the adults and children, respectively. For between-subject reliability (instruction-condition), median ICCs ranged 0.75-0.86 and 0.61-0.90 for the adults and children, respectively. It can be concluded that the above-mentioned sensor system can reliably record activities of daily living in a standardized setting.
NEW MODEL USING DSA TECHNIQUES AND COASIAN BARGAINING AGREEMENTS FOR SPECTRUM MANAGEMENT IN KOSOVO

In each country spectrum is scarce and expensive and as such it should treated carefully in terms of efficiency usage. The spectrum can be reallocated, reassigned and resold through agreements between the participants. In some places, interference exists (internalas well as external, i.e., from bordering countries) resulting in inefficient usage of spectrum, not respecting the law of telecommunication, the poor communication, loss of revenue, damage to telecommunication equipment etc. One of these places is Kosovo in GSM spectrum. In this thesis what we are addressing is how to avoid this problem and bring to participants an AGREEMENT that benefits all. With these kinds of agreements, the interference can be avoided, saving a lot of money and revenue will increase for both parties: unlicensed and licensed mobile operators (including the Government of Kosovo (GK)). On the other hand the positive externalities should happen, such a social cost, economical efficiency, political view and community integration. Our solution is based on Coase Theory and Problem of Social Cost and on another hand on the situation in Kosovo based on data from TRA of Kosovo and Serbia also data from Mobile Operators from both sides.
The effectiveness of the use of electrocautery with chondroplasty in treating chondromalacic lesions: A randomized prospective study.

PURPOSE To determine the clinical effect of electrocautery with arthroscopic chondroplasty on chondromalacic tissue. TYPE OF STUDY A randomized, prospective study. METHODS In a prospective study, 146 patients were randomly placed in either a control group (chondroplasty alone) or a treatment group (chondroplasty and electrocautery). Intraoperative findings in both treatment and control groups were classified by both the extent of chondromalacia and the number of compartments in which chondromalacia was diagnosed. In our study, we used 6 defined compartments: medial and lateral tibial plateau, medial and lateral femoral condyles, patella, and femoral trochlea. Patients were followed up at 1 year and evaluated using the Lysholm scale. Postoperative Lysholm scores were matched against compartment involvement and compared between groups. RESULTS There was no significant difference in the patients with grade 2 chondromalacia in either control or cautery group (P >.5). Groups with grade 3 chondromalacia showed a significant difference favoring the control group (P <.05). A significant difference was found in comparing 2-compartment chondromalacia between the 2 treatment cohorts, again, favoring the control group (P =.01). The remaining groups of multiple compartment chondromalacia showed no significant difference, indicating that the postoperative result was independent of the use of electrocautery. CONCLUSIONS This study shows that electrocautery as an adjunct to chondroplasty offers little benefit in the treatment of chondromalacic lesions and may, in fact, limit successful outcome.
Agent Orange exposure and cancer incidence in Korean Vietnam veterans: A prospective cohort study

During the Vietnam War, US and allied military sprayed approximately 77 million liters of tactical herbicides including Agent Orange, contaminated with 2,3,7,8‐tetrachlorodibenzo‐p‐dioxin. To the authors' knowledge, few studies to date have examined the association between Agent Orange exposure and cancer incidence among Korean veterans who were exposed to Agent Orange during the Vietnam War.
Children ' s Attitudes Toward Physical Activity in Classes

The purpose of the study was to determine if there were differences in attitudes toward physical activity for children in classes taught by specialists versus those taught by nonspecialists. Fourthand fifth-grade children (N=414) from four schools participated in the study. Two schools had P.E. specialists teaching the P.E. classes while the other two schools had classroom teachers teaching the classes. Attitudes were assessed by employing the Children's Attitude Toward Physical Activity (CATPA) inventory (Simon & Smoll, 1974). Although discriminant function analysis resulted in a significant difference between the attitudes of both groups of children, only 57.48% of the cases were correctly classified. These results suggest that teachers play a minimal role in children's attitudes toward physical activity. It was recommended that additional studies be conducted that examine and control for multiple factors influencing attitude formation.

An on-chip 1 Mb SRAM, that has three modes of operation, for application processors is developed to reduce power consumption. It operates at 300 MHz, with leakage of 25 /spl mu/A/Mb in the standby mode, and 50 /spl mu/A/Mb in the low-leakage-active mode.
Favorable Prognosis of Hyperdiploid Common Acute Lymphoblastic Leukemia May Be Explained by Sensitivity to Antimetabolites and Other Drugs: Results of an In Vitro Study

DNA hyperdiploidy is a favorable prognostic factor in childhood acute lymphoblastic leukemia (ALL). The explanation for this prognostic significance is largely unknown. We have studied whether DNA ploidy was related to cellular resistance to 12 drugs, assessed with the methyl-thiazol-tetrazo- lium assay, in samples of 74 children with common (CD10' precursor B-cell) ALL. Sixteen patients had hyperdiploid ALL cells and 58 patients had nonhyperdiploid ALL cells. Hyper- diploid ALL cells were more sensitive to mercaptopurine (median, 9.0-fold; P = .000003), to thioguanine (1.4-fold; P = .023), to cytarabine (1.8-fold; P = .016), and to l-asparaginase (19.5-fold; P = .022) than were nonhyperdiploid ALL cells. In contrast, these two ploidy groups did not differ significantly
Comovements of Returns and Volatility in International Stock Markets: A High-Frequency Approach

This paper analyzes common factors in the continuous volatility component, co-extreme and co-jump behavior of a sample of stock market indices. In order to identify those components in stock price processes during a trading day we use high-frequency data and techniques. We show that in most of the cases one common factor is enough to describe the largest part of the international variation in the continuous part of volatility and that this factorâ€™s importance has increased over time. Furthermore, we find strong evidence for asymmetries between extremely negative and positive co-extreme close-open returns and of negative and positive co-jumps across countries.
Modeling radiation sources of electronic components

Taking into account the integration of electronic components on the boards, the consideration of electromagnetic perturbations is more and more important. The aim of this paper is to present a methodology to model the electromagnetic radiation of electronic components or complete systems so as to predict and avoid future possible interferences. As application, two different systems are modeled: a microcontroller and an oscillator. The characterization of the oscillator allows us to validate the model at a high distance from the component. So, the magnetic field is simulated at 5cm over the circuit under test and it is compared to the measurements. Due to the increase of embedded electronic circuits present in the systems, modeling the emissions of electronic components has become important in the last years. The prediction of possible malfunctions caused by the interference between components mounted on the same board can be achieved by simulation. Consequently, the electronic board designers need the models of their components to predict the radiation and the possible interferences before the conception of the board. In this paper, a simple technique of modeling the magnetic field radiated by a component is presented. The component is modeled by an array of dipoles disposed in a two-dimensional plane. Some characteristics of these dipoles are fixed by the user; nevertheless this particularity provides simplicity for the process and consequently, velocity in the resolution of the equations. In order to apply the model to a real component, a microcontroller mounted on an autonomous board is used. Due to the fact that the measurements of the emissions at a certain height over the component are needed, the main difficulty of using this active device lies in the measurement of the phase of the magnetic field. The technique used is also presented. Due to the fact that the microcontroller used is mounted on an electronic board, the verification of the model at another distance high enough cannot be done because the radiation of the elements around it is measured. Therefore, another circuit is used: an oscillator. This circuit is modeled and afterwards the magnetic field at 5cm is simulated and compared with the measurements. II. PRESENTATION OF THE MODEL
A New Look at Where Our Food Dollars Go

The ERS market ing bill has been a popular stat ist ical series for food market observers interested in knowing the costs of gett ing food from farm to table. The market ing bill series ident if ied the costs of processing and market ing the raw farm commodit ies contained in a typical dollar's worth of U.S.-produced food and the share going to farmers. However, it is no longer possible to use the longstanding method for est imat ing the annual market ing bill because many of the data sources have been discont inued and the est imat ion procedures do not fully represent today's food economy.
Meta-service Design and Implementation for Content Delivery Network Cloud Environments

Storage has emerged as a typical kind of service in the cloud environment as the content delivery network (CDN) emerges and becomes widely-used. In this paper, we conducted a research on the management issues for such applications, and implemented some meta-services upon the underlying cloud services. The architecture of the system was described in detailed and the detailed design of four types of meta-services was further discussed. The implementation of the key components was presented one by one, depicting the functionalities of these meta-services. Experimental results show that the implemented prototype can work effectively and meaningful suggestions could be given according to users’ requests, and thus exhibit the advantages of employing the proposed meta-services. Moreover, by presenting a special case study, the feasibility and usability of meta-services in the CDN is further illustrated. DOI: http://dx.doi. org/10.11591/telkomnika.v10i7. 1582 Full Text: PDF
Performance of various magnetic core models in comparison with the laboratory test results of a ferroresonance test on a 33 kV voltage transformer

Ferroresonance is a nonlinear phenomenon and occurs in all voltage levels of power systems. One of the main elements of a ferroresonance circuit is saturable inductance. Existing electromagnetic transient programs such as EMTP present various models of magnetization characteristics of saturable cores. However, to study ferroresonance phenomenon, many papers have used single-valued characteristics for magnetic cores and ignored hysteresis effects. In this paper, some modeling methods of magnetic core characteristics are reviewed and the results of a ferroresonance test on a 33 kV voltage transformer are presented. Using the results of the voltage transformer no-load test, the magnetization characteristic is obtained and the magnetic core is modeled by various methods. The comparison between the experimental and simulation results shows that in analysis of some ferroresonance cases, the aspect of inherent variation of inductance in hysteresis loops is more important than the power loss introduced by these loops. Therefore, in such cases, the core characteristic must be represented by a hysteretic model. Otherwise, the simulation results may present significant errors
Embedding the features of the users' physical environments to improve the feeling of presence in collaborative Virtual Environments

The feeling of presence is essential for efficient interaction within Virtual Environments (VE). When a user is fully immersed within a VE through a large display system such as a big CAVE™, his feeling of presence can be altered because of disturbing interactions with his physical environment, such as collision with hardware parts of the system or loss of tracking. This alteration can be avoided by taking into account the physical features of the user and to embed them in the VE. Moreover, the 3D representation of these physical features can also be useful for collaboration between distant users because they can make a user aware of the physical limitations of the other users they are collaborating with. In this paper we present how we use the Immersive Interactive Virtual Cabin (IIVC) model to obtain this virtual representation of the physical environment of the user and we illustrate how it can be used to guide efficiently a user for a navigation task in a VE.
(201)Tl-SPECT, (1)H-MRS, and MIB-1 labeling index of central neurocytomas: three case reports.

BACKGROUND The proliferative activity and metabolic features of three central neurocytomas were investigated using the findings of thallium-201 single photon emission computed tomography ((201)Tl-SPECT) and proton magnetic resonance spectroscopy ((1)H-MRS), and the MIB-1 labeling index (MIB-1 LI). METHOD The early and delayed (201)Tl indices were calculated as the ratio of tumour to normal brain tissue uptake by (201)Tl-SPECT. In vivo single-voxel (1)H-MRS was performed with echo time of 272 msec to evaluate the metabolites including choline (Cho), N-acetyl aspartate (NAA) and creatine/phosphocreatine (Cre). An external standard reference was used to semiquantitate each metabolite. MIB-1 LI was determined in the surgical specimens. FINDINGS The MIB-1 LI was 0.5%, 1.2%, and 7.5% in an atypical central neurocytoma without intraventricular extension. Significant (201)Tl uptake was observed on delayed images in all three central neurocytomas. (1)H-MRS showed the high Cho peaks relative to the NAA and Cre peak. The signal at 3.55 ppm, which may be due to inositol or glycine, was observed in one central neurocytoma. INTERPRETATION Both (201)Tl-SPECT and (1)H-MRS did not reflect the proliferative potential of central neurocytomas.
The thermal-aware floorplanning for 3D ICs using Carbon Nanotube

Heat dissipation becomes one of the most serious challenges in three dimensional integrated circuits (3D ICs) designs. The through-silicon vias (TSVs) are effective on improving the thermal conductivity of 3D ICs. Many previous works have proposed thermal model for 3D ICs with TSVs, and formulated the TSV planning as a convex programming problem. On the other hand, besides excellent electrical and mechanical properties, thermal analysis of Carbon Nanotubes (CNTs) shows significant advantages in tall vias, indicating their promising applications as through-silicon vias in 3D ICs. In this paper, we integrate carbon nanotubes into the 3D ICs for inter layer connections. Thermal aware floor-planning approaches with TSV planning are also implemented. Experimental results show that compared to the copper TSVs, carbon nanotubes can reduce the total via number by over 89% for the same temperature.
Linguistic and co-speech gestural patterns of spatiotemporal metaphors in Indonesian

Abstract accepted for oral-presentation at the 15th International Cognitive Linguistics Conference, in Nishinomiya, Japan (6 - 11 August, 2019). Click on the dark pink Cite button (next to the Download button) for how to cite and view its DOI.The topic is about metaphorical representations of time in terms of space in Indonesian language and co-speech gesture. Here we try to add a few (methodological) notes that cannot be fit in a single-page abstract. Comments and/or feedback are welcome! (the project is still at its initial stage). In preparation for this abstract, we adopt the general guidelines from the LC period', waktu 'time', zaman 'era; period'. This approach is inspired by the corpus-based Metaphorical Pattern Analysis (MPA) (Stefanowitsch 2006) that focuses on the metaphorical collocational patterns of words referring to the metaphorical target domain (such as TIME). Such an approach allows us to identify a number of linguistic elements the "Time and Space Questionnaire" focuses on, such as types of motion verbs and prepositional phrases collocating with the temporal words; our corpus-based approach adds quantitative information for these collocational patterns regarding their token frequency. The linguistic data suggest that Indonesian also exhibits the two general patterns of temporal metaphors found in other languages (Sweetser & Gaby 2017:627): (i) one in which the passage of time is conceptualised as moving object toward a stationary observer or Ego (also called as MOVING-TIME metaphor as in "masa yang akan datang" 'time that will come'); (ii) one in which the ego is construed as moving along a temporal landscape with a moment in time is understood as a stationary object (also called as MOVING-EGO metaphor as in "sudah melewati zaman Orde Baru" 'already passed the era of the New Order'). Furthermore, linguistic evidence indicates that expressions for Front space is mapped onto the Future while Behind space is mapped onto the Past (cf. the abstract for the examples). Regarding the co-speech gesture dataFor the initial co-speech gesture data, we observe one episode of an Indonesian TV talk show Just Alvin. The episode is called "Golden Voice" featuring four top male Indonesian singers (the videos are available online and can be downloaded using Safari web browser in macOS Mojave (ver. 10.14.3)). The episode's central theme includes the main host (Alvin) asking the guests singers to narrate and tell how they know they have special music talents and distinctive voices. This allows the production of temporal expressions in the narratives. Our focus is on annotating gestures co-produced with verbal temporal expressions from the guests (e.g., reference to events in the past; the guests' career development over time up to the present). ELAN is used to annotate the co-speech gesture.
A Lidar Collaboratory Data Management System

A data management system has been developed for the Connecticut State University (CSU) Lidar Collaboratory to facilitate user authentication, scheduling of remote lidar instrumentation control sessions, storage and retrieval of lidar datasets and generation of new data products. In addition to providing for efficient archival and retrieval of lidar data products, a major design goal of the data management system is to support collaborative, multidisciplinary, atmospheric sciences research projects. In this paper, we describe the framework of the CSU Lidar Collaboratory data management system and how the system interacts with the data acquisition and data analysis software.
