On the Statistical Properties of the Capacity of Spatially Correlated Nakagami-M MIMO Channels
2008
This paper studies the statistical properties of the channel capacity of spatially correlated Nakagami-m multiple- input multiple-output (MIMO) channels. We have derived closed- form expressions for the probability density function (PDF), the cumulative distribution function (CDF), the level-crossing rate (LCR), and the average duration of fades (ADF) of the lower bound on the channel capacity. In order to study the impact of the spatial correlation on the channel capacity, the analysis of the statistical properties of the channel capacity is carried out for different receiver antenna spacings. It is observed that the antenna spacing has a significant influence on the spread and maximum val…
The Impact of Shadowing and the Severity of Fading on the First and Second Order Statistics of the Capacity of OSTBC MIMO Nakagami-Lognormal Channels
2011
Published version of an article in Wireless Personal Communications (2011), 1-16. Also available from the publisher at http://dx.doi.org/10.1007/s11277-011-0275-x This article presents a thorough statistical analysis of the capacity of orthogonal space-time block coded (OSTBC) multiple-input multiple-output (MIMO) Nakagami- lognormal (NLN) channels. The NLN channel model allows to study the joint effects of fast fading and shadowing on the statistical properties of the channel capacity. We have derived exact analytical expressions for the probability density function (PDF), cumulative distribution function (CDF), level-crossing rate (LCR), and average duration of fades (ADF) of the capacity…
The impact of spatial correlation on the statistical properties of the capacity of nakagami-m channels with MRC and EGC
2011
Published version of an article published in the journal: EURASIP Journal on Wireless Communications and Networking. Also available from the publisher at: http://dx.doi.org/10.1186/1687-1499-2011-116. OA In this article, we have studied the statistical properties of the instantaneous channel capacitya of spatially correlated Nakagami-m channels for two different diversity combining methods, namely maximal ratio combining (MRC) and equal gain combining (EGC). Specifically, using the statistical properties of the instantaneous signal-to-noise ratio, we have derived the analytical expressions for the probability density function (PDF), cumulative distribution function (CDF), level-crossing rat…
The influence of severity of fading on the statistical properties of the capacity of Nakagami-m channels with MRC and EGC
2010
In this article, we have studied the statistical properties of the capacity of Nakagami-m channels when spatial diversity combining, such as maximal ratio combining (MRC) and equal gain combining (EGC), is employed at the receiver. The presented results provide insight into the statistical properties of the channel capacity under a wide range of fading conditions in wireless links using L-branch diversity combining techniques. We have derived closed-form analytical expressions for the probability density function (PDF), cumulative distribution function (CDF), level-crossing rate (LCR), and average duration of fades (ADF) of the channel capacity. The statistical properties of the capacity ar…
Two fungal lanostane derivatives as phospholipase A2 inhibitors.
1996
The hydroalcoholic extract of Poria cocos and two lanostane derivatives isolated from it, pachymic acid (1) and dehydrotumulosic acid (2), were active as inhibitors of phospholipase A2 from snake venom when a polarographic method was used. Dehydrotumulosic acid exhibited an IC50 of 0.845 mM. These two compounds are structurally related to certain triterpenoids from Ganoderma and Schinus that have previously been described as competitive inhibitors of phospholipase A2. These comprise a new group of natural potential antiinflammatory agents due to their interaction with that enzyme.
Exploring the Potential of Short-Baseline Physics at Fermilab
2018
We study the capabilities of the short baseline neutrino program at Fermilab to probe the unitarity of the lepton mixing matrix. We find the sensitivity to be slightly better than the current one. Motivated by the future DUNE experiment, we have also analyzed the potential of an extra liquid Argon near detector in the LBNF beamline. Adding such a near detector to the DUNE setup will substantially improve the current sensitivity on non-unitarity. This would help to remove CP degeneracies due to the new complex phase present in the neutrino mixing matrix. We also study the sensitivity of our proposed setup to light sterile neutrinos for various configurations.
Strateginen ja ennakoiva toimintaympäristön seuranta : suomalaisten suuryritysten strategiajohtajien näkemyksiä toimintaympäristön seurannan merkityk…
2013
Toimintaympäristön seuranta on aktiivista tietämyksen luomista yritystä ympäröivästä toimintakentästä. Toimintaympäristön seuranta koostuu informaation keräämisestä, prosessoinnista, analysoinnista ja hyödyntämisestä. Jalostamalla irtonaista dataa ja informaatiota yritykselle merkitykselliseksi tietämykseksi, on mahdollista tukea yrityksen päätöksentekoa ja toiminnan suunnittelua. Ennakoiva ja strateginen toimintaympäristön seuranta on näin ollen tarkoituksenmukaista, yrityksen nykytilan ja tulevaisuuden huomioon ottavaa toimintaa, jolla pyritään yrityksen kannattavuuden ja jatkuvuuden varmistamiseen pidemmällä aikavälillä. Tutkimuksen tarkoituksena on luoda ymmärrystä strategisen ja ennako…
Tacitus on Titus? Visit to the Temple of Venus at Paphos
2020
This article deals with Titus? visit to the temple of Venus at Paphos in the second book of Tacitus? Historiae. I argue that apart from its other literary intentions already mentioned by scholars, this digression implicitly connects Titus not only with Aeneas but also with Julius Caesar. Titus? affair with Berenice that recalls Caesar?s affair with Cleopatra, Tacitus? allusions to Lucan?s De Bello Civili where Caesar?s visit to the tomb of Alexander the Great is described, the ?????Motiv and fortuna?s favour that characterise both Roman generals, all contribute to connect Titus with Caesar and allow the reader to view a parallel between the Flavian and the Julio-Claudian dynasty.
