    Evidence against strong correlation in 4d transition metal oxides, CaRuO3 and SrRuO3

    Full text link
    We investigate the electronic structure of 4d transition metal oxides, CaRuO3 and SrRuO3. The analysis of the photoemission spectra reveals significantly weak electron correlation strength (U/W ~ 0.2) as expected in 4d systems and resolves the long standing issue that arose due to the prediction of large U/W similar to 3d-systems. It is shown that the bulk spectra, thermodynamic parameters and optical properties in these systems can consistently be described using first principle approaches. The observation of different surface and bulk electronic structures in these weakly correlated 4d systems is unusual.Comment: 4 pages, 4 figure

    Transfer Inference Learning

    Techniques are described that combine machine learning with an edge network that includes IoT devices to yield an effective and efficient method of assessing a condition of an environment. An inference module that includes a machine-learning algorithm, installed and executing on the IoT devices, assesses a condition detected from multiple, different geographic locations. The IoT devices transfer sets of data and inferences as well as respective sets of confidence levels to converge on a verified set of inferences. The verified set of inferences is arrived at quickly and with a high confidence level

    Manifestation of lattice distortions in the O 1s spectra in Ca1-xSrxRuO3

    Full text link
    We investigate the effect of temperature on the electronic and crystal structures of Ca1-xSrxRuO3 via the evolution of O 1s core level spectra as a function of temperature and composition, x. O 1s spectra in SrRuO3 exhibit a dominant sharp feature at all the temperatures with a small trace of impurity feature at higher binding energies. The spectra in Ca doped samples, however, exhibit two distinct features. Analysis of the experimental spectral functions and the band structure results suggest that different Madelung potential at the two types of oxygen sites in the orthorhombically distorted structure leads to such splitting in the O 1s spectra. Interestingly, the energy separation of these two features becomes smaller at low temperatures in the Ca dominated samples concomitant to the observation of non-Fermi liquid behavior in their bulk properties. Such temperature evolution, thus, indicates a direct connection of the lattice degrees of freedom with the electronic properties of these compounds.Comment: four figure

    A Meta Analysis on Cardiac Vascular Disease with Obesity

    Increasing evidence suggests that inflammatory and immunological factors present in the general population play a role in the pathogenesis of cardiovascular disease in RA. More than that, RA is treated with a wide range of drugs, many of which have the potential to alter cardiovascular function. Non-steroidal anti-inflammatory medicines (NSAIDs) have been linked to an increased risk, whereas some treatments, like methotrexate and TNF inhibitors, have been linked to a reduced risk. Cardiac catheterization is just one of several possible procedures that can be done on the heart. More than a million people in the United States get cardiac catheterization each year. [1] Any time a surgeon makes incisions into a patient, they must be ready for the possibility of complications, whether they arise from the patient or the surgery itself. Fortunately, the prevalence of these issues has decreased considerably in recent years thanks to developments in cardiac catheterization equipment, advances in the experience of the operators, and the introduction of novel methods. The term "cardiac catheterization" can refer to either a right heart or a left heart catheterization, or both. Depending on the patient\u27s condition, interventional cardiologists can do either diagnostic or therapeutic operations. The dangers and difficulties that can arise during a diagnostic cardiac catheterization are briefly discussed in this article

    Internationalism, Soft power and India’s Vaccine Maitri

    Abstract- Internationalism as a concept means promoting cooperation and understanding among the nation-states and avoiding conflict. India’s understanding of Internationalism can be dated back to the period when the idea of “Vasudev Katumbukam” was proposed, which means the world is a family. In modern times India, after gaining Independence, has followed the concept of Internationalism and supported not only the formation of international organisations to promote international peace and cooperation but also advocated the policy of Internationalism in its foreign policy. The greatest threat to the idea of Internationalism is from the concept of nationalism because it prevents the modern nation-states from cooperating with each other. In this interconnected world, most of the global problems, such as climate change, terrorism, human trafficking, poverty, health problems etc., cannot be solved by the mere efforts of a single country; instead, the world needs cooperative actions to deal with it. Covid 19 pandemic has challenged the entire world’s health system and brought the world to a standstill; it has affected all nations irrespective of the level of development uniformly. Such a health crisis can only be dealt with the global cooperation. Through its “Vaccine Maitri” programme, India has established itself as the “Pharmacy of the World” and supplied the vaccines and essential medical equipment to impoverished countries, which helped India boost its Soft Power image in “Health diplomacy”. India has also tried to support the equitable vaccination drive through its Vaccine Maitri, whereas Western countries concentrated on “Vaccine Nationalism”. India’s Vaccine diplomacy has also helped promote its foreign policy as it provided vaccines not only to Neighbouring countries but also to African countries and other small Island nations, along with UN peacekeeping forces. This article will highlight India’s effort to deal with the pandemic through its Vaccine Maitri Programme and its soft power projection in health diplomacy. Keywords- Internationalism, Soft power, Vaccine diplomacy, Vaccine Maitri, Covid-19
