Joint Resource Allocation and UAV Scheduling With Ground Radio Station Sleeping

2021

Applications of Unmanned aerial vehicles (UAVs) have advanced rapidly in recent years. The UAVs are used for a variety of applications, including surveillance, disaster management, precision agriculture, weather forecasting, etc. In near future, the growing number of UAV applications would necessitate densification of UAV infrastructure (ground radio station (GRS) and ground control station (GCS)) at the expense of increased energy consumption for UAV communications. Maximizing the energy efficiency of this UAV infrastructure is important. Motivated by this, we propose joint resource allocation and UAV scheduling with GRS sleeping (GRSS). Further, we propose the use of coordinated multi-poi…

Immunotherapy in gastrointestinal cancer: Recent results, current studies and future perspectives

2016

The new therapeutic approach of using immune checkpoint inhibitors as anticancer agents is a landmark innovation. Early studies suggest that immune checkpoint inhibition might also be effective in patients with gastrointestinal cancer. To improve the efficacy of immunotherapy, different strategies are currently under evaluation. This review summarises the discussion during the European Organisation for Research and Treatment of Cancer Gastrointestinal Tract Cancer Translational Research Meeting in Mainz in November 2014 and provides an update on the most recent results of immune therapy in gastrointestinal cancers. Knowledge of potential relationships between tumour cells and their microenv…

Genomics and the gene transcription kinetics in yeast.

2007

As an adaptive response to new conditions, mRNA concentrations in eukaryotes are readjusted after any environmental change. Although mRNA concentrations can be modified by altering synthesis and/or degradation rates, the rapidity of the transition to a new concentration depends on the regulation of mRNA stability. There are several plausible transcriptional strategies following environmental change, reflecting different degrees of compromise between speed of response and cost of synthesis. The recent development of genomic techniques now enables researchers to determine simultaneously (either directly or indirectly) the transcription rates and mRNA half-lifes, together with mRNA concentrati…

RNAi knock-down mice: an emerging technology for post-genomic functional genetics

2003

RNA interference (RNAi) has been extensively used for sequence-specific silencing of gene function in mammalian cells. The latest major breakthrough in the application of RNAi technology came from experiments demonstrating RNAi-mediated gene repression in mice and rats. After more than two decades of functional mouse research aimed at developing and continuously improving transgenic and knock-out technology, the advent of RNAi knock-down mice represents a valuable new alternative for studying gene function in vivo. In this review we provide some basic insight as to how RNAi can induce gene silencing to then focus on recent findings concerning the applicability of RNAi for regulating gene fu…

Wetting properties at the surface of iota-carrageenan-based edible films

2006

International audience; Surface properties of edible films composed of a polymeric matrix of carrageenan in association with hydrophobic material were studied by contact angle measurements. The use of this technique not only in a static mode but also in a dynamic way enables investigation of surface hydrophobicity as well as surface wettability. The absorption flux inside the material can be estimated from the wetting kinetic, which can be very useful to quickly compare water barrier efficiency of the tested films. Comparison of carrageenan films with films containing known amounts of additives enables understanding and correlation of changes of the surface properties with the nature of use…

Ambush Marketing in China: Counterbalancing Olympic Sponsorship Efforts

2008

This paper provides an empirical insight into the perception and use of ambush marketing on the People's Republic of China public television network CCTV5 (the official Olympic broadcaster), by examining the commercials used by various corporations during its coverage of the 2004 Olympic Games in Athens. A five-point categorization is presented to distinguish between various methods of ambushing. Despite the efforts of the Beijing government to fight ambush marketing ahead of its Olympic Games in 2008, the results demonstrate that concerns about the practice of ambush marketing in China must be taken seriously. An analysis of 40 commercial spots was carried out, based on China's 2002 Olympi…

Uterus Transplantation

2018

Uterus transplantation (UTx) has been successfully introduced as a treatment option for women with absolute uterine factor infertility (AUFI). AUFI representing approximately 3% to 5% of the female general population is linked to either congenital uterine agenesis (Mayer-Rokitansky-Küster-Hauser syndrome), major congenital uterine malformation (hypoplastic uterus, fraction of bicornuate/unicornuate uterus), a surgically absent uterus, or an acquired condition (intrauterine adhesions, leiomyoma) linked to uterine malfunction that causes implantation failure or defect placentation. The world's first clinical uterus transplant was performed in 2000. However, a hysterectomy became necessary sho…

E-health progresses in Romania

2006

The paper is presenting the recent evolution of e-health aspects in Romania. Data presented are based on governmental reports. Surveys organized by the "Lucian Blaga" University of Sibiu and studies carried on by the national Institute for Research and Development in Informatics (I.C.I.) have shown that Romania has important health problems, from cardio vascular diseases (CVD) to cancer and infectious diseases, a high score on mortality and morbidity and a low one on natality. Poor management of the health sector did not help to solve all these problems. In the last 14 years there were several attempts to reform healthcare but none succeeded until now. The health insurance system is operati…

[The key role of public health medical resident education for future public health challenges].

2015

The Italian Committee of medical residents in Hygiene, Preventive Medicine and Public Health is a member of the Italian Society of Hygiene, Preventive Medicine and Public Health with the aim of developing a network among Italian resident in public health and promoting the educational path improvement through comparisons and debates between postgraduate medical schools. In this perspective, during last years account has been taken of some essential topics concerning education of public health medical residents, which represent future health-care and public health experts.Cross-sectional researches were conducted among Italian public health medical residents (PHMRs) through self-administered …
