Abstract

In this work we discuss about the problem of an electrically charged particle placed on the symmetry axis of an electrically charged ring in a quantum viewpoint. This problem should be an expanded version of the usual quantum ring and quantum corral. For this purpose, we present a detailed and pedagogical review about a version of the quantum ring focusing in mathematical aspects. As a new result, we calculate numerically the spectrum and wave functions related to charged particle located on the symmetry axis of charged ring and respective wave functions using two different ways: Numerov and perturbative method., Comment: 10 pages, 6 figures

Abstract

Radiologists today play a central role in making diagnostic decisions and labeling images for training and benchmarking artificial intelligence (AI) algorithms. A key concern is low inter-reader reliability (IRR) seen between experts when interpreting challenging cases. While team-based decisions are known to outperform individual decisions, inter-personal biases often creep up in group interactions which limit nondominant participants from expressing true opinions. To overcome the dual problems of low consensus and interpersonal bias, we explored a solution modeled on bee swarms. Two separate cohorts, three board-certified radiologists, (cohort 1), and five radiology residents (cohort 2) collaborated on a digital swarm platform in real time and in a blinded fashion, grading meniscal lesions on knee MR exams. These consensus votes were benchmarked against clinical (arthroscopy) and radiological (senior-most radiologist) standards of reference using Cohen's kappa. The IRR of the consensus votes was then compared to the IRR of the majority and most confident votes of the two cohorts. IRR was also calculated for predictions from a meniscal lesion detecting AI algorithm. The attending cohort saw an improvement of 23% in IRR of swarm votes (k = 0.34) over majority vote (k = 0.11). Similar improvement of 23% in IRR (k = 0.25) in 3-resident swarm votes over majority vote (k = 0.02) was observed. The 5-resident swarm had an even higher improvement of 30% in IRR (k = 0.37) over majority vote (k = 0.07). The swarm consensus votes outperformed individual and majority vote decision in both the radiologists and resident cohorts. The attending and resident swarms also outperformed predictions from a state-of-the-art AI algorithm.

Abstract

Glass is one of the oldest and most versatile manmade materials and has been used for centuries. One of the areas of significant research and progress is that of high-mechanical-resistance glass. Several processes can be used to maximize the mechanical strength of glasses, namely thermal or chemical treatments. Glass ceramics, obtained through controlled crystallization, can enhance the mechanical properties of these materials and, as long as the crystals remain small enough, transparent glass ceramics can be obtained. On the other hand, ion exchange can strengthen the glass surface and reduce failure. As a result, ceramization followed by ion exchange can further enhance the mechanical characteristics of the parent glass. Aluminosilicate glasses and glass ceramics are known to present excellent transparency and chemical durability, plus good mechanical behavior; therefore, a lithium aluminosilicate glass composition was studied in order to obtain transparent glass ceramics, followed by an ion exchange process, and its mechanical properties were studied. Transparent glass ceramics were obtained, with an increase of ~15% in hardness over the parent glass. The glass ceramics were then subjected to an ion exchange treatment in a KNO3 bath, in order to further enhance the mechanical properties, without hindering the optical transmittance. The combination of heat treatment and chemical treatment resulted in a cumulative hardness increase of ~25%, from 620 ± 10 HV, for the as-cast glass and from 773 ± 23 HV for the ion-exchanged glass ceramic. Regarding the indentation fracture toughness, values obtained for the glass ceramics were similar to those obtained for the cast glass, yielding no noticeable change. Indentation fracture toughness increased after the ion exchange treatment of the glass ceramic, since a much higher load was necessary to obtain a measurable indentation, indicating higher indentation fracture strength.

Abstract

ObjectivesTo describe patterns of multimorbidity in six diverse Latin American and Caribbean countries, examine its effects on primary care experiences, and assess its influence on reported overall health care assessments.MethodsCross-sectional data are from the Inter-American Development Bank's international primary care survey, conducted in 2013/2014, and represent the adult populations of Brazil, Colombia, El Salvador, Jamaica, Mexico and Panama. Robust Poisson regression models were used to estimate the extent to which those with multimorbidity receive adequate and appropriate primary care, have confidence in managing their health condition, and are able to afford needed medical care.ResultsThe prevalence of multimorbidity ranged from 17.5% in Colombia to 37.3% in Jamaica. Most of the examined conditions occur along with others, with diabetes and heart disease being the two problems most associated with other conditions. The proportions of adults with high out-of-pocket payments, problems paying their medical bills, seeing multiple doctors, and being in only fair/poor health were higher among those with greater levels of multimorbidity and poorer primary care experiences. Multimorbidity and difficulties with primary care were positively associated with trouble paying for medical care and managing one's conditions. Nonetheless, adults with multimorbidity were more likely to have received lifestyle advice and to be up to date with preventive exams.ConclusionsMultimorbidity is reported frequently. Providing adequate care for the growing number of such patients is a major challenge facing most health systems, which will require considerable strengthening of primary care along with financial protection for those most in need.

39. Low-dose naltrexone: a novel adjunctive treatment in symptomatic alopecias?

Abstract

Naltrexone is a competitive antagonist of μ, κ and γ opioid receptors, used for treatment of alcoholism and opioid addiction. Low-dose naltrexone (LDN) is defined as daily doses ranging from 1mg to 5mg. This is purported to have a paradoxical effect that leads to an increase in endogenous opioids, including beta-endorphins, which have anti-inflammatory properties. Theses mechanisms may also justify their possible role in the treatment of inflammatory conditions. The aim of this article is to discuss the use of LDN as an adjuvant therapeutic option in symptomatic alopecias presenting with trichodynia. Trichodynia is defined as scalp discomfort of variable intensity presenting as diffuse or localized dysesthesia and may be described by patients as pain, pruritus, or burning. These are common symptoms in patients with hair loss that negatively impacts quality of life. Scalp discomfort may be refractory to conventional therapies and does not yet have a specific therapeutic guideline. For these cases, LDN would be a possible alternative to be added to the therapeutic arsenal owing to its anti-inflammatory properties, analgesic potential, low cost, and few adverse effects described. Further studies are needed to standardize dosing, better understand its mechanism of action, and evaluate its potential therapeutic indications.
