The Internet of Things (IoT) and Cloud computing are gaining popularity due to their numerous advantages, including the efficient utilization of internetand computing resources. In recent years, many more IoT applications have beenextensively used. For instance, Healthcare applications execute computations utilizing the user’s private data stored on cloud servers. However, the main obstaclesfaced by the extensive acceptance and usage of these emerging technologies aresecurity and privacy. Moreover, many healthcare data management system applications have emerged, offering solutions for distinct circumstances. But still, theexisting system has issues with specific security issues, privacy-preserving rate,information loss, etc. Hence, the overall system performance is reduced significantly. A unique blockchain-based technique is proposed to improve anonymityin terms of data access and data privacy to overcome the above-mentioned ***, the registration phase is done for the device and the user. After that, theGeo-Location and IP Address values collected during registration are convertedinto Hash values using Adler 32 hashing algorithm, and the private and publickeys are generated using the key generation centre. Then the authentication is performed through login. The user then submits a request to the blockchain server,which redirects the request to the associated IoT device in order to obtain thesensed IoT data. The detected data is anonymized in the device and stored inthe cloud server using the Linear Scaling based Rider Optimization algorithmwith integrated KL Anonymity (LSR-KLA) approach. After that, the Time-stamp-based Public and Private Key Schnorr Signature (TSPP-SS) mechanismis used to permit the authorized user to access the data, and the blockchain servertracks the entire transaction. The experimental findings showed that the proposedLSR-KLA and TSPP-SS technique provides better performance in terms of higherprivacy-preserving rate, lower info

Seasonal Dynamics of Turbidity Maximum in the Muthupet Estuary, India

引用

journal of Ocean University of China 2015年第5期14卷 765-777页

作者： priya K.L. jEGATHAMBAL P. jAMES E.j. School of Civil Engineering Karunya University

Results are presented of the longitudinal and vertical profiling of salinity and suspended particulate matter(SPM) at the Muthupet estuary, India, during a one year period under widely varying freshwater flow conditions. Freshwater flow was available during post-monsoon and monsoon. An up-estuary shift in the location of estuarine turbidity maxima(ETM) was observed during the transition from post-monsoon to pre-monsoon and further it shifted downstream during the transition from pre-monsoon to monsoon, thereby exhibiting a pronounced seasonal cycle. The salinity intrusion was dependent on the freshwater discharge and was expressed as a power function of freshwater flow, explaining 97% of the variance. The formation of a salt plug in Muthupet estuary and its seasonal dynamics were observed, which is not an identified feature of any of the Indian estuaries studied so far. The geographical positions of salt plug and ETM core were more or less the same during their formation. The occurrence of two ETM during the LW of post-monsoon and the absence of ETM during monsoon explains the strong seasonal variation in the formation of ETM. The primary factor affecting the formation of ETM was identified as the freshwater flow over an annual cycle; the resuspension of sediments by tidal current affecting the formation on a flood/ebb cycle was secondary. The extent of shift of ETM was found to be an inverse logarithmic function of the freshwater discharge. The separation between ETM intrusion and salinity intrusion increased two fold with the increase in ETM intrusion.

Photometric investigation of eight ultra-short period eclipsing binaries from OGLE

引用

Research in Astronomy and Astrophysics 2020年第8期20卷 113-120页

作者： Shanti priya D. Ravi Raja P. Rukmini j. Raghu Prasad M. Vineet S.Thomas Department of Astronomy Osmania UniversityHyderabad-500007TelanganaIndia The University of Akron AkronOH44325USA

We performed a detailed photometric analysis of eight ultra-short period eclipsing binaries(USPEBs) using the Wilson-Devinney method. We present the modeled light curves and derived photometric solutions. The USPEBs with period(P)≤0.21 d considered in our study belong to W-subtype having shallow contact factor(f)~0.7 and later spectral types. The absolute parameters for these short-period binaries were derived applying empirical relations. We discuss the evolutionary stage of these USPEBs using the mass-radius, color-density and period-color diagrams. The objects showed poor metallicities, and some objects were even found to be existing around fully convective limits. The period distribution of USPEBs exhibited a sharp cut-off at 0.22 d;however, we observed significant deficits for our objects in the literature. We examined the statistics of USPEBs studied to date(in terms of the distribution of period, mass ratio and component temperatures of USPEBs) and observed that a dominant distribution of component temperatures for these USPEBs was towards lower temperatures.

Optical and near-infrared photometric study of NGC 6724

Research in Astronomy and Astrophysics 2018年第2期18卷 37-42页

作者： Reda Bendary Ashraf Tadross priya Hasan Anas Osman Ahmed Essam National Research Institute of Astronomy & Geophysics 11421-Helwan Cairo Egypt Maulana Azad National Urdu University Gachibowli Hyderabad - 500 032 India

BVRI CCD photometry of the poorly studied open cluster NGC 6724 has been carried out down to a limiting magnitude of V-20 mag. The stars of the cluster have been observed using the Newtonian focus （f/4.84） of the 74-inch telescope at Kottamia Astronomical Observatory in Egypt. Also, the 2MASS - jHK system is used to confirm the results we obtained. The main photometric parameters have been estimated for the present object; the diameter is found to be 6 arcmin, the distance is 15304-60pc from the Sun and the age is 900＋50Myr. The optical reddening E（B - V） = 0.65 mag, while the infrared reddening is E（j - H） = 0.20 mag. The slope of the mass function distribution and the relaxation time estimations indicate that cluster NGC 6724 is dynamically relaxed.

Genome-Wide DNA Binding of GBF1 IsModulated by Its Heterodimerizing ProteinPartners, HY5 and HYH

引用

Molecular Plant 2014年第2期7卷 448-451页

作者： Hathi Ram Pushp priya Mukesh jain Sudip Chattopadhyay National Institute of Plant Genome Research Aruna Asaf Ali Marg New Delhi 110067 India Department of Biotechnology National Institute of Technology Mahatma Gandhi Avenue Durgapur 713209 India

Dear Editor, In today＇s post-genomic era where direct targets of manytranscription factors have been identified, it is becomingincreasingly evident that transcriptional networks are verycomplex. Heterodimerization of transcription factors is oneof the several methods by which these complex transcrip-tional networks are formed. By heterodimerization, DNA-binding specificity and affinity, transactivation properties,and ultimately cell physiology might be altered （Naar et al.,2001）. The formation of heterodimers has the potential torecognize additional binding sites and increase the rangeof DNA-binding specificity （Foster et al., 1994）. Further, het-erodimerization also allows the production of new proteinconfigurations. For example, the protein STF1 from soybeancan dimerize with GBF proteins and this dimerization bringstogether the acidic region from STF1 and the proline-richregion of the GBF proteins into one binding element （Cheonget al., 1998）. These results highlight the importance and/orconsequences of heterodimerization of transcription factorsat particular locus. However, to understand the complex tran-scriptional networks, it is important to investigate that howheterodimerization affects the whole-genome-wide bind-ing and transcriptional properties of a transcription *** in this study, we have investigated genome-wide DNAbinding of bZIP transcription factor GBF1, and analyzed theimportance of its heterodimerization with HY5 and HYH forits genome-wide binding. We have found that GBF1 bindingsites are enriched within the 1-kb regions upstream to thetranscription start sites of target genes. Moreover, the bind-ings of GBF1 to most of its targets are largely dependent onHY5, while HYH only affects the binding of GBF1 to somespecific sites.
