Evidence against strong correlation in 4d transition metal oxides, CaRuO3 and SrRuO3
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
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
Critical success factors for implementation of supply chain management in Indian small and medium enterprises and their impact on performance
AbstractGlobalization of the economy, e-business, and introduction of new technologies pose new challenges to all organizations especially for small and medium enterprises (SMEs). In this scenario, successful implementation of supply chain management (SCM) can give SMEs an edge over their competitors. However, SMEs in India and other developing countries face problems in SCM implementation due to lack of resources and direction. Against this backdrop, this paper identified 13 critical success factors (CSFs) for implementation of SCM in SMEs and studied their impact on performance of Indian SMEs. Top management commitment, long–term vision, focus on core strengths, devoted resources for supply chain, and development of effective SCM strategy emerged as the most pertinent CSFs. To measure improvement in performance, the authors considered different measures related to customer service and satisfaction, innovation and growth, financial performance, and internal business. Results are analysed by testing research propositions using standard statistical tools
