Anyonic correlation functions in Chern-Simons matter theories

We show that in spinor-helicity variables, two-point and three-point functions in Chern-Simons matter theories can be obtained from either the free boson theory or the free fermion theory with an appropriate coupling constant dependent anyonic phase factor which interpolates nicely between the free fermion theory and the free boson theory. For specific examples of four-point functions involving spinning operators we argue that the correlators can again be reproduced from the free theory with an appropriate phase factor.Comment: 23 pages, v2 : Subsection 5.4 on $\langle TTTT\rangle$ added.

CLUSTERING OF NETWORK DEVICES TO FORM A VIRTUAL NETWORK SERVICE CONTROL PLANE

Enterprise networks often consist of multiple sites that often operate in a hierarchical manner for routing traffic among the sites, as well as to/from external networks. With the deployment of enterprise or hybrid cloud services within enterprise networks, such as cloud productivity services, communication services, etc. many policies, security, and/or performance requirements have to be met that often depend on the knowledge of sources and destinations, including their user/group information, security information, credentials, etc. However, it is often difficult to aggregate such information to scale in an end-to-end manner, similar to routing prefixes, as it can be difficult to store such information within the hardware resources of a network. In order to address such issues, techniques are presented herein through which a clustering capability can be enabled for existing and/or newly deployed physical and/or virtual networking devices in order to form a virtual network service control plane that can facilitate scaling for the deployment of hybrid cloud services. As described in further detail herein, networking protocols can be utilized to provide intent and guidance regarding the replication capability of databases in distributed operating system infrastructure within a set of networking devices such that the cluster forms the virtual network service control plane

Lead-Free Hybrid Perovskite Light-Harvesting Material for QD-LED Application

Most recently, organic-inorganic semiconductor light harvester materials, have arisen as a new class of functional element and attracts the research community due to its outstanding optoelectronic properties. Organic-inorganic perovskites are solution process that is easy for the fabrication of devices at low temperature. Additionally, up to date, perovskite quantum dots have emerged as the most efficient light harvester for LEDs and display applications, with high color purity, color tunability, and photoluminescence quantum yield up to 100%. However, the presence of lead in organic-inorganic perovskites and the stability issue of perovskite materials are the significant challenges for the research community. To date, some lead substitute materials have been tried to enhance the film morphology and production of the less toxic light harvester. In this chapter, we focus on the lead substitution on B sight with homovalent cations like Sn2+, Mn2+, Cd2+, and Zn2+ cations. These lead substitutions not only reduce the toxicity of perovskite material while these dopants also enhance the optical and performance of LEDs. We also included the LEDs application of lead substituted perovskite quantum dots (PQDs) that may be useful for the environmental friendly and highly performing perovskite quantum dot LEDs (PQ-LEDs) shortly

A social profile of deaths related to sickle cell disease in India : a case for an ethical policy response

India accounts for 14.5 percent of the global SCD newborns, roughly over 42,000 a year, second to sub-Saharan Africa. Despite the availability of cheap diagnostic and treatment options, SCD remains a largely neglected disease within healthcare policy and practice. Epidemiological modeling based on small, often dated, regional studies (largely from sub-Saharan Africa) estimate that between 50 and 90 percent of affected children will/die before the age of 5 years. This premise, coupled with targets of reducing under 5 mortality (SDG 4), privileges public health interventions for screening and prevention of new births, undermining investments in long-term health and social care. This paper presents a retrospective, descriptive analysis of the socio-demographic profile of 447 patients diagnosed with sickle cell or sickle-beta thalassemia, who died following admission at a tertiary care entre in India. We used anonymized hospital records of 3,778 sickle cell patients, admitted in pediatric and adult/medical wards between January 2016 and February 2021. A majority of hospital deaths occurred in the second and third decades of life, following a hospital admission for a week. The overall mortality during 2016–2019 was 14% with little gender difference over time. Contrary to our expectations, the number of hospital deaths did not increase during the first year of the COVID-19 pandemic, between 2020 and 2021. The conclusion highlights the importance of longitudinal, socio-demographic data on deaths as providing important insights for identifying ethical policy interventions focused on improving SCD outcomes over time, reducing inequities in access to care, and preventing what might be considered “excess” deaths
