OPTION IMPLIED VIX, SKEW AND KURTOSIS TERM STRUCTURES

Comparisons are made of the Chicago Board of Options Exchange (CBOE) skew index with those derived from parametric skews of bilateral gamma models and from the differentiation of option implied characteristic exponents. Discrepancies can be due to strike discretization in evaluating prices of powered returns. The remedy suggested employs a finer and wider set of strikes obtaining additional option prices by interpolation and extrapolation of implied volatilities. Procedures of replicating powered return claims are applied to the fourth power and the derivation of kurtosis term structures. Regressions of log skewness and log excess kurtosis on log maturity confirm the positivity of decay in these higher moments. The decay rates are below those required by processes of independent and identically distributed increments.

An alternative sedation option for special care patients: combined inhalation sedation with nitrous oxide and oxygen and intravenous sedation with midazolam

This article highlights an alternative sedation technique by providing inhalation sedation with nitrous oxide and oxygen alongside intravenous sedation with midazolam as an additional option for patients within special care dentistry. Two case reports are described, as well as a short overview of the available literature on this technique and the indications, advantages and disadvantages. This technique should be considered alongside other sedation techniques. As with all treatment for which sedation is provided, each case needs to be considered on an individual basis and the most appropriate option selected following discussion with the patient. CPD/Clinical Relevance: Although single sedation techniques provide a good level of sedation to facilitate dental treatment for the majority of patients, it is desirable to have an awareness of alternative sedation options that may be available for patients.

AGE RELATED MACULAR DEGENERATION (ARMD) CLINICAL PROFILE AND MANAGEMENT

Age Related Macular Degeneration (ARMD) next to cataract is the leading cause visual loss in elderly. My study is to focus on cleanical profile of Age Related Macular Degeneration with effective Ayurveda management to increasing in average longitivity of an individual with advance in science and technology along with traditional management.In research scenario it has been demonstrated that choroidal neovascular lesion of Age Related Macular Degeneration. Account for most of severe loss of vision attributed to this condition. My study tries to give additional option and contribution of Ayurveda to patient affected with Age Related Macular Degeneration. Macula is area which correspond to centre of vision. There are two types Dry and Wet ARMD based on appearance of exudates and tiny haemorrhage in the macular area . in wet AMD treatment of Raktpitta should be followed. Though description of macular degeneration is not described is classics . Gradual loss of vision in Timira we can assume this regenerative pathology as Prakopita Vatalakshana in Drushti Mandala . Inn proper Tarpak Kapha result in weakening of function and death of life sensing cells of macula . In dry Age Related Macular Degeneration this cells breakdown slowly and result in loss of central vision . These can be stated Kaphavata Drushtijanya Timira . In case of wet AMD abnormal blood vessels start to grow under macula and eventually bleed . This explains Raktpitta Drushti . Management of Age Related Macular Degeneration should be done on the principle of Vatavyadhi with Rasayan Chikitsa .

JomMachineLearning

When a user intends to custom make a name card, the very first step that the printing service provider would ask for is their name card design artwork, yet users do not have their name card design artwork. The client would feel frustrated with the designer to create artwork that does not meet their requirements. The designer would also feel the same as the artwork has been rejected regularly by the client. From the primary data survey result, most respondents agreed that they have a clear idea in mind but have difficulty expressing their idea to the designer. The opinions concluded from the interviews would there be another choice for the user to design an artwork besides hiring a designer. This study has proposed a designer matching platform to match the client's preference and designer's talent and an online artwork design editor as an additional option for the user.

A novel CO2 storage concept that reduces the leakage risk

<p>Geologic carbon storage is needed to reach carbon neutrality and eventually achieve negative emissions. In the classical concept of storing CO<sub>2</sub> in deep sedimentary aquifers, supercritical CO<sub>2</sub> has a lower density than the resident brine. CO<sub>2</sub> is therefore buoyant and the safety and effectiveness of the storage concept rely on the caprock sealing capacity to prevent CO<sub>2</sub> leakage. To reduce the risk of CO<sub>2</sub> leakage and widen the CO<sub>2</sub> storage options, we propose an innovative concept that consists in injecting CO<sub>2</sub> in reservoirs where the temperature and pressure of the resident brine are above the critical point ( 373.95 ºC and 22.064 MPa for pure water). At such conditions, which can be found at depths between 3 to 5 km in volcanic areas, CO<sub>2</sub> is denser than the resident water and thus, sinks. The sinking tendency reduces the risk of CO<sub>2</sub> leakage to the surface even in case of damaged or absent caprock. CO<sub>2</sub> storage in supercritical reservoirs can potentially become an additional option to the existing storage concepts aimed at significantly reduce CO<sub>2</sub> emissions. We estimate that every 100 wells drilled into supercritical reservoirs could store between 50 to 500 Mt/yr of CO<sub>2</sub>.</p><p> </p><p>REFERENCES</p><p>Parisio, F. and Vilarrasa, V. (2020).

Human Enhancements and Voting: Towards a Declaration of Rights and Responsibilities of Beings

The phenomenon and ethics of “voting” will be explored in the context of human enhancements. “Voting” will be examined for enhanced humans with moderate and extreme enhancements. Existing patterns of discrimination in voting around the globe could continue substantially “as is” for those with moderate enhancements. For extreme enhancements, voting rights could be challenged if the very humanity of the enhanced was in doubt. Humans who were not enhanced could also be disenfranchised if certain enhancements become prevalent. Voting will be examined using a theory of engagement articulated by Professor Sophie Loidolt that emphasizes the importance of legitimization and justification by “facing the appeal of the other” to determine what is “right” from a phenomenological first-person perspective. Seeking inspiration from the Universal Declaration of Human Rights (UDHR) of 1948, voting rights and responsibilities will be re-framed from a foundational working hypothesis that all enhanced and non-enhanced humans should have a right to vote directly. Representative voting will be considered as an admittedly imperfect alternative or additional option. The framework in which voting occurs, as well as the processes, temporal cadence, and role of voting, requires the participation from as diverse a group of humans as possible. Voting rights delivered by fiat to enhanced or non-enhanced humans who were excluded from participation in the design and ratification of the governance structure is not legitimate. Applying and extending Loidolt’s framework, we must recognize the urgency that demands the impossible, with openness to that universality in progress (or universality to come) that keeps being constituted from the outside.

Migraine Prophylaxis Using Novel Monoclonal Antibody Injections in a Commercial Pilot

BACKGROUND: Frequent migraine headaches are disabling and aeromedically disqualifying. Four new monoclonal antibody medications, targeting calcitonin gene-related peptide (CGRP), have been approved by the U.S. Food and Drug Administration (FDA) since 2018, with more expected in the coming years. These medications present new alternatives for the treatment of migraine unresponsive to other therapeutic and prophylactic agents.CASE REPORT: We present a case of a 45-yr-old commercial pilot who presented with migraine headaches increasing in frequency to 1315 per month in spite of the use of propranolol for prophylaxis and sumatriptan for abortive treatment of the headaches. Upon presentation, he was not flying due to his frequent headaches and he was started on monthly subcutaneous injections of fremanezumab. Following his second injection, his headaches stopped entirely, and he has continued on the medication and not experienced another migraine headache. He underwent an aeromedical neurology evaluation and consideration for Authorization of Special Issuance of Medical Certificate, which was granted by the Federal Aviation Administration (FAA).DISCUSSION: This is the first case to our knowledge of the successful use of an anti-CGRP monoclonal antibody medication in an active pilot. The pilot appears to be a super responder to the medication, having achieved complete remission of a nearly life-long condition. Though only a small portion of treated individuals will see this sort of response, these medications represent an effective additional option for migraine prophylaxis in the pilot population.Garber MA, Sirven JI, Roth RS, Hemphill JM.
