On a generalized basic series and Rogers-Ramanujan type identities

In this paper, we give the generalization of MacMahon's type combinatorial identities. A generalized $q$-series is interpreted as the generating function of two different combinatorial objects, viz., restricted $n$-color partitions and weighted lattice paths which give entirely new Rogers–Ramanujan–MacMahon type combinatorial identities. This result yields an infinite class of 2-way combinatorial identities which further extends the work of Agarwal and Goyal. We also discuss the bijective proof of the main result. Forbye, eight particular cases are also discussed which give a combinatorial interpretation of eight entirely new Rogers–Ramanujan type identities

Achieve High Verifiability using Proxy Resignature and TPA in User Revocation within the Cloud

Using Cloud Storage, users can remotely store their data and enjoy the on-demand high quality applications and services from cloud. User can get relaxation from the burden of local data storage and maintenance. In addition, we have an efficient probabilistic query and audit services to improve the performance of approach based on periodic confirmation. So that the users existing blocks by themselves do not need to sign up and download the proxy by using the idea of re-signatures, we block the user revocation on behalf of existing users to the cloud, the signing in again to allow for..In addition, a public Verifier always without retrieving all of the data shared data is able to audit the integrity of Cloud, even if part of the shared data has been signed by the cloud again. Moreover, our system by multiple auditing functions with batch verification audit is able to support. Experimental results show that our system fairly can improve the efficiency of user cancellation. Data storage and sharing services in the cloud, users can easily modify and share data in a group. Shared data to ensure unity in public, group users shared data to calculate signatures on all blocks need to be verified. Shared data by different users in different blocks are usually due to data revisions have been signed by individual users. The proposed system considers proxy resign, if the user from group get revoked. Cloud is able to resign block, which was created previously by the revoked user with existing users private kye. As a result, user revocation can be greatly improved, and capacity of computing and communications resources of existing users can be saved. DOI: 10.17762/ijritcc2321-8169.15062

Substituted benzocoumarin derivatives: synthesis, characterization, biological activities and molecular docking with ADME studies

Herein, an efficient and convenient method for the synthesis of 4-(substitutedphenyl)-1,2-dihydro-2-oxo-6-(2-oxo-2H-benzo[g]chromen-3-yl)pyridine-3-carbonitrile derivatives have been reported using ammonium acetate as catalyst. The structures of synthesized compounds were confirmed using FT-IR, 1H, 13C-NMR and LC-MS spectroscopic techniques. The synthesized compounds have been evaluated for antibacterial activity against bacterial strains by agar diffusion method at different concentrations. Further, all the targeted compounds were screened for anti-oxidant and anti-cancer studies by DPPH and MTT assay methods at different concentrations. Compound 4b displayed good antioxidant and anticancer (against MCF-7 cell line) activity. Further, the binding capability for the synthesized compounds (4a–j) was analyzed by molecular docking studies using human peroxiredoxin 5 (PDB ID: 1HD2) and P38 MAP kinase (PDB ID: 1OUK) protein. Further, the physicochemical properties were analysed from ADME studies respectively

Comparison of neuroimaging by CT and MRI and correlation with neurological presentation in eclampsia

Background: The objective of the study was to compare computed tomography (CT) and magnetic resonance imaging (MRI) findings of eclampsia patients with respect to neurological signs and symptoms.Methods: This is a prospective observational study, 25 patients of eclampsia were studied, statistical analysis was done by Fishers’ exact and chi square test.Results: All patients in our study presented with antepartum or intrapartum eclampsia with neurological features ranging from headache, altered consciousness to coma. On neuroimaging by MR transiently high T2 signal intensity in the cerebral cortex and sub cortical white matter was seen, including edema. With MR angiography generalized vasospasm was also seen in 40% cases. MRI was found to be co-relating more than CT with the neurological presentation and had 90% sensitivity and 100% sensitivity.Conclusions: Symptoms like visual blurring, loss of vision and ophthalmological signs in eclampsia suggest occipital lobe involvement. Magnetic resonance imaging abnormalities in eclampsia correlate well with clinical findings as compared to CT and can be better imaging modality in eclampsia patients

Automated Defect Detection and Characterization on Pulse Thermography Images Using Computer Vision Techniques

Defect detection and characterization plays a vital role in predicting the life span of materials. Defect detection using appropriate inspection technologies at various phases has gained huge importance in metal production lines. It can be accomplished through wise application of non-destructive testing and evaluation (NDE). It is important to characterize defects at an early stage in order to be able to overcome them or take corrective measures. Pulse thermography is a modern NDE method that can be used for defect detection in metal objects. Only a limited amount of work has been done on automated detection and characterization of defects due to thermal diffusion. This paper proposes a system for automatic defect detection and characterization in metal objects using pulse thermography images as well as various image processing algorithms and mathematical tools. An experiment was carried out using a sequence of 250 pulse thermography images of an AISI 316 L stainless steel sheet with synthetic defects. The proposed system was able to detect and characterize defects sized 10 mm, 8 mm, 6 mm, 4 mm and 2 mm with an average accuracy of 96%, 95%, 84%, 77%, 54% respectively. The proposed technique helps in the effective and efficient characterization of defects in metal objects

Bupivacaine 0.5% vs. levobupivacaine 0.5% for epidural anaesthesia for caesarean section: a comparative study

Background: Levobupivacaine has been purported to be as efficacious as Bupivacaine for epidural anaesthesia in recent literature.Methods: With the intent to study the same in caesarean section cases in our set up, we observed various intra- and post-operative variables in two groups (Levobupivacaine and Bupivacaine) of 60 healthy parturients. Sixty parturients for elective caesarean section were allocated randomly to receive epidural block with 10-20 ml of either 0.5% Levobupivacaine with Fentanyl 25µg or 0.5% Bupivacaine with Fentanyl 25µg to reach T6 level.Results: Mean total volume in Bupivacaine group was 15.23ml and in Levobupivacaine group was 12.76 ml. The difference was statistically significant. There was significant difference between the groups in the sensory block. The onset of analgesia was earlier in Levobupivacaine group. Mean time was 6.20 minutes in Bupivacaine group and 4.36 minutes in Levobupivacaine group. The duration of motor block was significantly short in Levobupivacaine group. Mean Time for recovery from motor block in Bupivacaine group was 2.5 hours and in Levobupivacaine group 1.5 hours. Mean time to achieve T6 height was earlier in Levobupivacaine group i.e. 16.46 minutes in Bupivacaine group and 13.26 minutes in Levobupivacaine group. Duration of postoperative analgesia was similar. There was no significant difference in neonatal outcome.Conclusions: Levobupivacaine was found to fare better than Bupivacaine in the studied intra and post-operative parameters and is hence recommended over racemic Bupivacaine for epidural block in patients undergoing elective cesarean section

Perceptions of neighborhood social environment and drug dependence among incarcerated women and men: a cross-sectional analysis

Abstract Background Perception of neighborhood social environment can influence an individual’s susceptibility to drug dependence. However, this has never been examined with a jailed sample, where frequent transitions between local jails and disadvantaged neighborhoods are common. Understanding these associations could aid in the design of targeted programs to decrease drug dependence and recidivism among the incarcerated. Methods For this study, 596 women and men from three Kansas City jails were surveyed over the course of six months in 2010. Drug dependence was assessed with DSM-IV criteria. Independent variables included fear of one’s neighborhood, perceived level of neighborhood violence, and social capital. All data were self-reported and were analyzed using logistic regression. Results Controlling for gender and age, fear of neighborhood violence was associated with increased odds of having drug dependence (OR = 1.27, CI 1.02, 1.58) and a higher level of social capital prior to incarceration was associated with lower odds of drug dependence (OR = 0.65, CI 0.44, 0.96). Mental health problem diagnosis and past year intimate partner violence were significant mediating factors. Gender and race/ethnicity were significant moderating factors between neighborhood disadvantage and drug dependence. Conclusions Our study suggests that drug dependence programs for women and men who cycle between jails and communities require both individual- and community-level interventions. To be most effective, programs at the community-level should focus on helping specific groups navigate their communities, as well as address individual health needs associated with drug dependence.Peer Reviewe
