Resummed prediction for Higgs boson production through bbˉb\bar{b} annihilation at N3^3LL

We present an accurate theoretical prediction for the production of Higgs boson through bottom quark annihilation at the LHC up to next-to-next-to-next-to leading order (N$^3$LO) plus next-to-next-to-next-to-leading logarithmic (N$^3$LL) accuracy. We determine the third order perturbative Quantum Chromodynamics (QCD) correction to the process dependent constant in the resummed expression using the three loop bottom quark form factor and third order quark soft distribution function. Thanks to the recent computation of N$^3$LO corrections to this production cross-section from all the partonic channels, an accurate matching can be obtained for a consistent predictions at N$^3$LO+N$^3$LL accuracy in QCD. We have studied in detail the impact of resummed threshold contributions to inclusive cross-sections at various centre-of-mass energies and also discussed their sensitivity to renormalization and factorization scales at next-to-next-to leading order (NNLO) matched with next-to-next-to leading logarithm (NNLL). At N$^3$LO+N$^3$LL, we predict the cross-section for different centre-of-mass energies using the recently available results in \cite{Duhr:2019kwi} as well as study the renormalization scale dependence at the same order.Comment: 19 pages, 4 figures, 2 table

Non-existence of Hopf real hypersurfaces in complex quadric with recurrent Ricci tensor

In this paper, we first introduce the notion of recurrent Ricci tensor which is the generalization of parallel Ricci tensor in the complex quadric Qm = SOm+2 /SOm SO2. After then, we investigate real hypersurfaces of the complex quadric Qm with the condition of recurrent Ricci tensor and give the glimpse of full classification with this condition

Comparative Analysis of External Links of video Using Apriori and RFP

Recently popularity of video sharing site is increased. People can watch video from any other site other than video sharing site. To increase popularity of video external links concept is introduced. Now in video sharing site through external link is video or audio content can be embedded into external website. User can copy that URL of that embedded link & post on their own blog or website. In this paper our intension is study of relevancy of videos and & increase the popularity & measure the quantification. With the results collected from two major video sharing site like Youtube & Youku we observed that these links have an various impact on popularity. Overall, videos which are collected from external links are analyzed and accuracy & popularity is measured DOI: 10.17762/ijritcc2321-8169.15079

Analysis of External Links of video using Association Rule Mining

Now a days, to increase the popularity of video sharing site they provide a external link, so that their video or audio content can be embedded into external website. User can copy that URL of that embedded link & post on their own blog or website. In this paper our intension is to increase the popularity & measure the quantification. We provide the measurement & analysis on this external link. With the results collected from two major video sharing site like You tube & Youku we observed that these links have an various impact on popularity. Videos that have been uploaded for ten months in Youku, around 20% of views can come from external links. Next, we analyzed that correlation between internal & external link. Another observation is Youku has comparatively more impact than You tube. DOI: 10.17762/ijritcc2321-8169.15026

On next to soft corrections to Drell-Yan and Higgs Boson productions

We present a framework that resums threshold enhanced large logarithms to all orders in perturbation theory for the production of a pair of leptons in Drell-Yan process and of Higgs boson in gluon fusion as well as in bottom quark annihilation. We restrict ourselves to contributions from diagonal partonic channels. These logarithms include the distributions $((1-z)^{-1} \ln^i(1-z))_+$ resulting from soft plus virtual (SV) and the logarithms $\ln^i(1-z)$ from next-to-SV (NSV) contributions. We use collinear factorisation and renormalisation group invariance to achieve this. The former allows one to define a Soft-Collinear (SC) function which encapsulates soft and collinear dynamics of the perturbative results to all orders in strong coupling constant. The logarithmic structure of these results are governed by universal infrared anomalous dimensions and process dependent functions of Sudakov differential equation that the SC satisfies. The solution to the differential equation is obtained by proposing an all-order ansatz in dimensional regularisation, owing to several state-of-the-art perturbative results available to third order. The $z$ space solutions thus obtained provide an integral representation to sum up large logarithms originating from both soft and collinear configurations, conveniently in Mellin $N$ space. We show that in $N$ space, tower of logarithms $a_s^n/N^\alpha \ln^{2n-\alpha} (N), a_s^n/N^\alpha \ln^{2n-1-\alpha}(N) \cdots$ etc for $\alpha =0,1$ are summed to all orders in $a_s$.Comment: 55 Pages, 3 Table

Improved Storage Security using IDS and Performance using Container De-Duplication

Due to enormous increase in use of web services in our day today life, web services have moved to multitier design where in web server runs the application front-end logic and data are outsourced to a database or file server. In our system, we will implement secure de-duplication which is a technique for eliminating duplicate copies of data, it has been largely used in cloud storage to reduce storage space and upload bandwidth with Container security, an IDS system that models the network acts as user sessions across both front-end web server and back-end database. By monitoring both the web and subsequent database requests, we are capable to search out attacks that an independent Intrusion Detection System (IDS) unable to identify. In this system, each user requesting for our application will be allocated separate container. The container based web architecture not only fasters profiling of causal mapping, but it also provides an isolation that obstruct future session hijacking attacks .Each user will hold de-key which is a new construction in which users do not require to manage any keys on their own but as an alternative securely distribute the convergent key shares across multiple servers. We implement De-key to demonstrate that De-key incurs limited overhead in realistic environments

A rare pediatric renal tumor: classic congenital mesoblastic nephroma: two cases and review of literature

Background Mesoblastic nephroma (Boland’s tumor) is the most common benign renal tumor occurring in infants and neonates. The most common presentation is abdominal mass, but it can have varied presentations because of associated paraneoplastic syndromes. Majority of these tumors can be cured with surgical excision alone; however, long-term follow-up is required for recurrence or metastasis. Histopathologically, it is divided into two subtypes: classic and cellular. The less common cellular congenital mesoblastic nephromas have cellular elements in them and tend to have a more malignant potential.Patients and methods Two patients were studied over a period of 2 years from June 2010 to June 2012.Results By reporting two patients presenting in the infantile period with classic congenital mesoblastic nephromas, an attempt is made in this paper to characterize the clinical behavior of this variety of renal tumors. Hypertension and paraneoplastic syndromes can be associated with this tumor. Herein we compare our experience with other similar cases reported in the literature.Conclusion When renal tumors occur in infancy or at neonatal age, mesoblastic nephroma should be kept in mind. Association of hypertension and paraneoplastic syndromes should be looked for. Surgery is usually curative and postoperative follow-up for recurrence is required, more so in cellular variety

Evaluation of drug use health related quality of life and pharmacoeconomics in autoimmune skin disorders: focus on blistering skin disorders-a prospective observational study

Background: Autoimmune skin disorders (ASDs) are complex diseases triggered by autoantibodies action against epidermal antigens or the dermo epidermal junction. Although rare, they present high morbidity, affecting the quality of life (QoL) of patients and financial status of patient.Methods: This prospective, observational study was carried out in department of dermatology for 2-3 months after ethical approval. Drug usage pattern, heath related QoL (HRQOL) by using DLQI (Dermatology life quality index) and cost were evaluated in patients with ASDs. Statistical analysis was done using Microsoft excel office 2019 and rechecked with SPSS (version 23.0). P<0.001 was considered as statistically significant.Results: Out of 73 patients enrolled, 32 were male and 41 were female with the mean age was 48.27±14.93 years; 55% patients had autoimmune blistering skin disorders (AIBDs) and 45% having other ASDs (OADs). Pemphigus vulgaris (PV) (35%) being the most common among all ASDs. Systemic steroid (60.27%), topical steroid (79.45%), levocetirizine (63%) were most commonly prescribed drugs. Mean DLQI score at baseline and after treatment was 11.64±2.49 and 6.8±2.75 respectively. It was highly significant statistically (p<0.0001). Total cost of illness per month was 813.64±481.21 INR. Maximum percentage variation in cost was seen with prednisolone (1706.28%).Conclusions: ASDs have a female bias and inflict severe impairment to the QoL of patients. Appropriate drug therapy with corticosteroids and other adjuvant drug lead to positive impact on QoL. There was very wide price variation of different brands of the same generic most commonly prednisolone and levocetirizine
