Systematic study of SYBR green chromophore reveals major improvement with one heteroatom difference

2021

Five nucleic acid binding cyanine dyes were synthesized and their photophysical properties were evaluated. Changing a single heteroatom in the chromophore causes major differences both in brightness and photostability between the dyes. With such alteration, the brightness of the chromophore increased two-fold compared to the one found in SYBR Green I. peerReviewed

Rhythmic Memory Consolidation in the Hippocampus

2022

Functions of the brain and body are oscillatory in nature and organized according to a logarithmic scale. Brain oscillations and bodily functions such as respiration and heartbeat appear nested within each other and coupled together either based on phase or based on phase and amplitude. This facilitates communication in wide-spread neuronal networks and probably also between the body and the brain. It is a widely accepted view, that nested electrophysiological brain oscillations involving the neocortex, thalamus, and the hippocampus form the basis of memory consolidation. This applies especially to declarative memories, that is, memories of life events, for example. Here, we present our vie…

Evaluation of Nigeria Universities Websites Quality : A Comparative Analysis

2018

The use and continuous use of the website in the developed countries universities are predominant, and the developing countries universities are heightening their effort in the aspect of education technology. The reason why one university website is better than the other concerning quality and accessibility is the focus of this study and this prompt evaluation of 141 Universities in Nigeria across the Federal, State, and the Private ownership. We opted for a hybrid approach to cover the gap in the previous studies. WebQual and SITEQUAL as a framework is adopted based on the web analytical tools. The study contributes theoretically by combining two website quality theories to explain the inh…

Music adviser : emotion-driven music recommendation ecosystem

2017

In respect of the big amounts of music available in the web, people met the problem of choice. From another side, practically unlimited resources can bring us new opportunities in the music context. Efficient data management engines which are smart and self managed are in demand nowadays in the music industry to handle music sources amounts of which are coming towards to infinity continuously. This study demonstrates feasibility of the emotional based personalization of music recommendation system. There is still gap between human and artificial intelligence, robotics do not have intuition and emotions which represent critical point of recommendations. Taking into account significant influe…

Opiskelijoiden motivaatio ja siihen vaikuttavat tekijät selkärangattomien peruslajintuntemuksen kurssilla

2017

Lajintuntemustaidot ovat tärkeä bio- ja ympäristötieteiden alojen ammattilaisten osaamisalue. Lajintuntemuksella on myös merkitys osana laajempaa luonnontuntemusta, sillä esimerkiksi ekosysteemien rakenteen ja toiminnan ymmärtäminen ilman lajintuntemusta olisi hankalaa. Lajintuntemustaitojen on todettu heikentyneen luonnontieteiden korkeakouluopiskelijoilla, minkä lisäksi lajintuntemuksen opiskelu korkeakouluissa on todettu yllättävän vaikeaksi. Kaikki opiskelijat eivät koe lajintuntemustaitojen olevan edes tärkeitä tai kiinnostavia. Lajintuntemuksen opiskelua tulisikin kehittää siten, että opiskelijoiden motivaatio paranisi tieteellisesti, sisällöllisesti ja menetelmällisesti laadukkaalla …

Learn to Cache: Machine Learning for Network Edge Caching in the Big Data Era

2018

The unprecedented growth of wireless data traffic not only challenges the design and evolution of the wireless network architecture, but also brings about profound opportunities to drive and improve future networks. Meanwhile, the evolution of communications and computing technologies can make the network edge, such as BSs or UEs, become intelligent and rich in terms of computing and communications capabilities, which intuitively enables big data analytics at the network edge. In this article, we propose to explore big data analytics to advance edge caching capability, which is considered as a promising approach to improve network efficiency and alleviate the high demand for the radio resou…

IEEE Access Special Section Editorial: Exploiting the Benefits of Interference in Wireless Networks: Energy Harvesting and Security

2018

Interference used to be viewed as a harmful factor in wireless networks, which can reduce the quality of information transmission. To combat against interference, many interference management techniques have emerged. Due to the latest research advances, interference (or noise) can also be exploited to offer some benefits to wireless networks. The first aspect is that interference in multi-user networks can be collected as a green power supply for the transceivers, known as wireless energy harvesting. Another application is that one can generate artificial noise to disrupt the adversarial eavesdropping, and guarantee the security of wireless networks. Therefore, conventional interference man…

A Double Auction Mechanism for Virtual Resource Allocation in SDN-based Cellular Network

2016

The explosively growing demands for mobile traffic service bring both challenges and opportunities to wireless net- works, among which, wireless network virtualization is proposed as the main evolution towards 5G. In this paper, we first propose a Software Defined Network (SDN) based wireless virtualization architecture for enabling multi-flow transmission in order to save capital expenses (CapEx) and operation expenses (OpEx) significantly with multiple Infrastructures Providers (InPs) and multiple Mobile Virtual Network Operators (MVNOs). We for- mulate the virtual resource allocation problem with diverse QoS requirements as a social welfare maximization problem with transaction cost. Due…
