Platylomia radha
No full text8. - Platylomia radha (Distant, 1881) Dundubia radha Distant, 1881 Cosmopsaltria radha (Distant), DISTANT, 1889; Platylomia radha, DISTANT, 1906); CHOU & LEI, 1997. Platylomia radha (tribu des Platylomiini) est une espèce de très grande taille (67 mm de longueur totale pour 127mm d'envergure), à teinte dominante brune et caractérisée, chez les mâles, par des opercules disproportionnés, en forme de gouges acérées, s'écartant largement de l'abdoipen, et qui sont recouverts d'une pruinescence d'un blanc immaculé; aussi sont-ils bien visibles au travers des ailes tout à fait transparentes (fig. 2, K). P. radha est une espèce dendrophile, d'assez haute futaie et principalement héliophile. Cette espèce est, littéralement, "vociférante" qui, de la même place haut perchée et installée tête en haut, fait entendre, de préférence sous le soleil, de longues et fortes séquences d'appel, entrecoupées de silences irréguliers dépassant souvent les 10 à 15 minutes. Sa cymbalisation comprend des périodes relativement courtes de haut sifflement (près de 2 s) relayées, après une brève coupure, par des périodes plus longues (8 à 9 s) de grésillements très rapprochés émis en alternance régulière. Sa carte d'identité acoustique (C. I. A), est analyséeci-dessous(fig. 11). a: oscillogramme d'une portion d'une vingtaine de secondes de la cymbalisation d'appel transcrite en temps réel et restituant deux séquences entières, Sql et Sq2. b: oscillogramme d'un espace-temps arbitraire étirant une seconde et demie du plein signal centrée, plage inversée en a, sur la transition entre les deux séquences: entre le train de modules sifflés (ms), identiques et très proches entre eux, qui terminent la séquence Sql, et le train de modules grésillés, mg, comprenant la répétition régulière d'un motif grésillé de 1 + 3 groupes de signaux lesquels débutent, après une brève baisse de tonalité (tf, pour tonalité de fond), la séquence Sq2. c: spectrogramme étiré suivant l'oscillogramme b et mettant en évidence les plages d'occupation fréquentielle relatives aux divers groupes de signaux et dont l'efficacité sonore est en relation avec la richesse formantique. Les modules sifflés, identiques entre eux, possèdent une échelle d'harmoniques montant jusqu'à près de 16000 Hz; la plage correspondant à la tonalité de fond (tf) ne dépasse pas 12500 Hz, tandis que le grésillement alternant est rendu par la succession régulière de motifs cons¬ titués parun module sifflé (1), riche en harmoniques, que suivent trois modules de fond (2, 3 et 4). d: tracé spécifique du spectre moyen. Femelle et accouplement non observés.Published as part of Boulard, Michel, 2001, Statut acoustique et comportement sonore de quelques Cigales thaïlandaises.

Universal Oneness as the Ulterior Motive of the Incarnation of Radha and Krishna
No full textMy Affair with Radha, the debut work of Kunal Desai is the dedication to his readers who firmly believe in the divine couple Radha and Krishna. The intention of the author was to spread the awareness of the significance of divine love to the world through the example of Radha and Krishna who remain to be the epitome of transcendental oneness. The human life that has been influenced in multiple ways throughout the life time, fails to overcome the temptations and eventually ends up in misery. A solution to all the misery in the world is to experience the feeling of oneness from within, which uplifts the individual from selfishness to selflessness and eventually the individual feels empathy towards all things. A world with such human beings with the feeling of oneness, will obviously be in harmony and without any miseries.
 
DNA Triplexes in chemistry biology and medicine
No full textThe formation of DNA triple helices offers the possibility of selectively targeting specific genes to control their expression in vivo. This anti-gene strategy provides powerful tools for the development of therapeutics (anti-cancer drugs, drugs for viral infections) at the transcriptional level. DNA triplexes are formed when an oligonucleotide binds to the major groove of double helical DNA; the third strand can bind in either a parallel motif, or an anti-parallel motif. The requirement of low pH for the protonation of cytosine in the parallel binding motif makes the formation of triple helices difficult under physiological conditions. Described in this thesis is a novel method for the synthesis of the deoxycytidine analogue, 2-amino-3-methyl-5-(2’-deoxy-?-D-ribofuranosyl)pyridine (MeP). The phosphoramidite monomer of MeP was synthesised and incorporated as a “protonated” cytidine analogue into triplex forming oligonucleotides (TFOs). It was compared with other cytosine analogues, 5-methyl-(2’-deoxy-?-D-ribofuranosyl)cytosine (MeC), 2’-Omethyl MeP (MePOMe), and 2’-O-aminoethyl MeC (MeCAE). Triplex stability studies indicate that over the pH range 6.2-8.0, the general trend observed in terms of melting temperature (Tm) was as follows: MeP > MeC > MePOMe > MeCAE. DNase I footprinting studies indicate that at pH 7.5, MeP, when incorporated into the TFO, enhances the stability of the triplex by three-fold relative to MeC. In addition, UV melting, DNase I footprinting, and gel electrophoresis studies were carried out on a triplex formed by the binding of a TFO containing MeP and a 5’-Psoralen to a target duplex. This revealed the benefits of the combined modifications on the stability of the resultant triplex. “Soaking” experiments (in vivo) were also performed with this TFO on the organism C. elegans (the worms were soaked in solutions of the TFO for TFO delivery), to observe whether the TFO would induce loss-of-function phenotypes. Tm measurements indicated that in the pH range 6.6-8.0, photo-crosslinking of the TFO to the duplex created a shift in the triplex Tm of ~ + 26 °C when compared to the un-crosslinked triple

BARON: Base-Station Authentication Through Core Network for Mobility Management in 5G Networks
No full textFifth-generation (5G) cellular communication networks are being deployed on applications beyond mobile devices, including vehicular networks and industry automation. Despite their increasing popularity, 5G networks, as defined by the Third Generation Partnership Project (3GPP), have been shown to be vulnerable against fake base station (FBS) attacks. An adversary carrying out an FBS attack emulates a legitimate base station by setting up a rogue base station. This enables the adversary to control the connection of any user equipment that (inadvertently) connects with the rogue base station. Such an adversary can gather sensitive information belonging to the user. While there is a large body of work focused on the development of tools to detect FBSs, the user equipment will continue to remain vulnerable to an FBS attack. In this paper, we propose BARON, a defense methodology to enable user equipment to determine whether a target base station that it is connecting to is legitimate or rogue. BARON accomplishes this by ensuring that the user receives an authentication token from the target base station which can be computed only by a legitimate and trusted entity. As a consequence, receiving such an authentication token from a base station ensures legitimacy of the base station. We evaluate BARON through extensive experiments on the handover process between base stations in 5G networks. Our experimental results show that BARON introduces an overhead of less than 1% during handover completion, which is 10000× lower than the overhead reported by a state-of-the-art method. BARON is also effective in thwarting an FBS attack and quickly recovering connection to a legitimate base station. Cyber Securit
Dirasah Muqaranah ‘an Hukm al-Zawaj Bayna Rudha’a Alban Bunuk al-Laban Fi Manzhur Fuqaha al-Aqdamin wa al-Mu’ashirin
No full textThe issue of Breast Milk Bank is a contemporary fiqh issue, and its ruling is not found in classical fiqh. However, classical Moslem scholars have studied the issue of radha in an unusual way known as al-major (breast milk put into the baby's mouth), al-south (breast milk put through the nose), and or putting breast milk into the baby's mouth using bottles and cups. Therefore, the fuqaha differed on the prohibition of marriage because of radha' unusually or indirectly such as radha' from a breast milk bank. After conducting a comparative analysis, the author concludes that the majority of classical scholars from the Hanafi, Maliki, Shafi'i and Hambali madhhabs, and most contemporary fiqh scholars, think that indirect radha', such as radha' from a breast milk bank, makes marriage prohibited. They reason that indirect radha' has the same effect as direct radha' regarding the growth of the baby's flesh and bones. Meanwhile, the Zhahiri school of classical jurisprudence and some contemporary jurisprudence scholars such as Yusuf al-Qardhawi think that indirect radha' such as radha' from a breast milk bank is not called radha'. According to them, radha' is only if the baby suckles directly on the mother's nipple. Hence, they think that radha' from a breast milk bank does not lead to the prohibition of marriage

NMR Structure of the extended Myb cognate sequence and modeling studies on specific DNA-Myb complexes
No full textThe recognition sequence of the Myb protein has been recently described to be pyAACKGHH (where py = T/C, K = G/T, and H = A/C/T), modifying the earlier identification as pyAACKG [Ording, E., et al. (1994) Eur. J. Biochem. 222, 113-120]. We had earlier determined the solution structure of the minimal cognate sequence TAACGG, choosing py = T and K = G, embeded in a 12-mer DNA duplex by NMR and related computational techniques [Radha, P. K., et al. (1995) Biochemistry 34, 5913-5912]. To understand the structural significance of the above modification and the role of the variability in the recognition sequence, we have investigated here the solution structure of a different DNA segment, d-ACAACTGCAGTTGT, which contains the extended Myb cognate site, CAACTGCA. The three-dimensional structure of the 14-mer duplex has been determined from NMR data by relaxation matrix and restrained molecular dynamics calculations. The structure of the above cognate sequence in the 14-mer duplex has been compared with that of the cognate sequence, TAACGG, in the 12-mer duplex and also with that in the NMR structure of the Myb DNA binding domain (R2R3)-DNA complex determined by Ogata et al. recently [Ogata, K., et al. (1994) Cell 79, 639-648]. The comparison highlighted differences in several structural parameters for the cognate sites in the DNA segments. Modeling studies by taking out the protein from the complex and presenting it with 12-mer and 14-mer DNA structures indicated that the protein induces structural alterations to drive the cognate site to a reasonably conserved structure. The extent of similarity of the derived structures was, however, dependent on the base sequences. Base changes in the minimal cognate sequence in the 12-mer-protein complex and in the 14-mer-protein complex so as to match the sequence of Ogata et al. produced a more conserved structure of the complex. A reverse exercise, in which the Ogata DNA in the complex was mutated to match the 12-mer and 14-mer minimal cognate sequences, complemented the above observations of the subtle sequence dependence of the structure in the complex. On the other hand, base changes in the extension did not influence the DNA-protein complex structure significantly. We also observed that the structural changes in the protein were very minor when different DNA sequences or different DNA structures were presented to it. These observations would be of interest from the point of view of DNA-Myb recognition
