Perverse Effects of Non-sterilized Interventions on Spot Foreign Exchange Rates
(SAGE Publications Ltd, 2019-06)
We study the effects of non-sterilized intervention on a spot foreign exchange (forex) rate using a multi-period game-theoretical model which involves an unspeci?ed number of competitive traders, a ?nite number of strategic ...
Does Poverty Among Immigrants Adapt to Country of Residence? Turks in Germany and Denmark
(John Wiley & Sons Ltd., 2019-02)
We use data on Turkish immigrants in two European welfare states, Denmark and Germany, and data on Turks at home. Unlike in most studies of immigrant poverty, we thus control for the differences in immigrant composition. ...
Immediate and delayed effects of nutrient-sensing in fruit fly Drosophila melanogaster
(Elsevier B.V., 2019-07)
Starting in late 1980's, Bill Timberlake and associates conducted a series of experiments on anticipatory contrast which showed that rats’ feeding decisions were regulated by the nutritive value of currently ingested and ...
Working in the Midst of Trauma: Exposure and Coping in News Camera Operators
(Routledge, 2019-05)
News camera operators are among the first responders to crises, emergencies, and other human suffering. This study is an attempt in the literature to explore trauma exposure and coping in news camera operators who are ...
Design of anti-reflective graded height nanogratings for photovoltaic applications
(IEEE Computer Society, 2017-08)
Design of nanogratings with graded heights is proposed for solar-cell applications. The designed structure gives rise to absorption enhancement in solar-cells by reducing the reflection losses and focusing the incoming ...
The impact of stapling technique and surgeon specialism on anastomotic failure after right?sided colorectal resection: an international multicentre, prospective audit
(2018)
Aim
There is little evidence to support choice of technique and configuration for stapled anastomoses after right hemicolectomy and ileocaecal resection. This study aimed to determine the relationship between stapling ...
The effect of different optical zone diameters on the results of high-order aberrations in femto-laser-assisted in situ keratomileusis
(SAGE PUBLICATIONS LTD, 2019)
Purpose:
To evaluate the postoperative high-order aberration differences of femto-LASIK surgery in 6.5 and 7?mm optic zones.
Patients and Methods:
We retrospectively reviewed 80 eyes of 40 patients with myopia or myopia ...
Prediction of Intramolecular Reorganization Energy Using Machine Learning
(AMER CHEMICAL SOC, 2019)
Facile charge transport is desired for many applications of organic semiconductors (OSCs). To take advantage of high-throughput screening methodologies for the discovery of novel OSCs, parameters relevant to charge transport ...
A bioartificial rat heart tissue: Perfusion decellularization and characterization
(SAGE PUBLICATIONS LTD, 2019)
Despite remarkable advancement in the past decades, heart-related defects are still prone to progress irreversibly and can eventually lead to heart failure. A personalized extracellular matrix-based bioartificial heart ...
A method comparison for D-Dimer measurement
(Turkish Biochemical Society, 2018)
OBJECTIVES:D-dimer is a fibrin degradation product, a small protein fragment present in the blood after a blood clot is degraded by fibrinolysis. The determination of D-dimer concentration may ...
Information-Theoretic Feature Selection for Human Micro-Doppler Signature Classification
(IEEE-Inst Electrical Electronics Engineers Inc, 2016-05)
Micro-Doppler signatures can be used not only to recognize different targets, such as vehicles, helicopters, animals, and people, but also to classify varying activities, e.g., walking, running, creeping, and crawling. For ...
Maximum-weight scheduling with hierarchical modulation for lower delay
(Elsevier Gmbh, Urban & Fischer Verlag, 2016)
In this paper, hierarchical modulation is used in conjunction with maximum-weight scheduling to achieve lower transmission delays. Via hierarchical modulation, the scheduled user has the option to transmit to two users ...
Transmission strategies and resource allocation for fading broadcast relay channels
(Elsevier Gmbh, Urban & Fischer Verlag, 2015)
In this paper the broadcast relay channel, where the source communicates with multiple destinations with the help of a single relay is studied. Five different transmission protocols, direct transmission, multihop (MH), ...
A Low-Complexity Policy for Outage Probability Minimization With an Energy Harvesting Transmitter
(IEEE-Inst Electrical Electronics Engineers Inc, 2017-04)
Outage probability in an energy harvesting (EH) block-fading communication system is studied in the finitehorizon online setting. First, the offline version of the problem is considered, and formulated as a mixed integer ...
The Impact of Incapacitation of Multiple Critical Sensor Nodes on Wireless Sensor Network Lifetime
(IEEE-Inst Electrical Electronics Engineers Inc, 2017-06)
Wireless sensor networks (WSNs) are envisioned to be utilized in many application areas, such as critical infrastructure monitoring, and therefore, WSN nodes are potential targets for adversaries. Network lifetime is one ...
Diversity Analysis of Hierarchical Modulation in Wireless Relay Networks
(IEEE-Inst Electrical Electronics Engineers Inc, 2014-07)
