Estimation of height from the length of humerus in western region of Maharashtra

An attempt has been made to find out correlation and to drive a regression formula between the length of humerus and height of an individual, in western region of Maharashtra. The material consisted of 200 undergraduate and post-graduate medical students of age group 20 to 30 years from western region of Maharashtra. The length of humerus is measured by asking the subject to flex the elbow joint. The flexor surfaces of arm and forearm made an angle of 90 degree. The lateral epicondyle was felt and marked with skin marking pencil. Acromion point was traced by moving finger over clavicle’s lateral end and was marked. The distance between two points was measured by spreading caliper, both side humerus length was taken. The measured length was subtracted by 2.0 mm as the acromion point is 2 to 5 mm above humeral head. Height of the subject was measured with standard height measuring instrument in anatomical position. The results obtained were analyzed and attempt was made to derive a formula between length of humerus and total height of an individual. The result shows that there is definite correlation between the two.

Policy Gradients for CVaR-Constrained MDPs

We study a risk-constrained version of the stochastic shortest path (SSP) problem, where the risk measure considered is Conditional Value-at-Risk (CVaR). We propose two algorithms that obtain a locally risk-optimal policy by employing four tools: stochastic approximation, mini batches, policy gradients and importance sampling. Both the algorithms incorporate a CVaR estimation procedure, along the lines of Bardou et al. [2009], which in turn is based on Rockafellar-Uryasev's representation for CVaR and utilize the likelihood ratio principle for estimating the gradient of the sum of one cost function (objective of the SSP) and the gradient of the CVaR of the sum of another cost function (in the constraint of SSP). The algorithms differ in the manner in which they approximate the CVaR estimates/necessary gradients - the first algorithm uses stochastic approximation, while the second employ mini-batches in the spirit of Monte Carlo methods. We establish asymptotic convergence of both the algorithms. Further, since estimating CVaR is related to rare-event simulation, we incorporate an importance sampling based variance reduction scheme into our proposed algorithms

Relative Value Iteration for Stochastic Differential Games

We study zero-sum stochastic differential games with player dynamics governed by a nondegenerate controlled diffusion process. Under the assumption of uniform stability, we establish the existence of a solution to the Isaac's equation for the ergodic game and characterize the optimal stationary strategies. The data is not assumed to be bounded, nor do we assume geometric ergodicity. Thus our results extend previous work in the literature. We also study a relative value iteration scheme that takes the form of a parabolic Isaac's equation. Under the hypothesis of geometric ergodicity we show that the relative value iteration converges to the elliptic Isaac's equation as time goes to infinity. We use these results to establish convergence of the relative value iteration for risk-sensitive control problems under an asymptotic flatness assumption

COMPARATIVE STUDY OF APAMARGA AND KUTAJA PRATISARANIYA KSHARA IN THE MANAGEMENT OF SECOND DEGREE HAEMORRHOIDS (ARSHA)

Arsha (haemorrhoid) is known to mankind as a common anorectal disease. According to Ayurveda Mithyaaaharvihara i.e., unhealthy lifestyle is one of the major aetiological factor of Arsha and it is unavoidable in this busy modern lifestyle due to junk food habits and lack of time. This habit causes vitiation of Doshas which affect digestive fire (Mandagni) and cause constipation. Hence constipation is one of the major causes for hemorrhoid. It is also known as “Mahagadas” which means difficult to cure. Acharya Sushruta has mentioned that Ksharakarma is one of the effective methods of treating Gudarsha. In these research article efforts has been made to treat II0 Haemorrhoids by Ksharakarma. Aim: To evaluate the effect of Apamarg and Kutaj Pratisaaraniya Kshar in the management of hemorrhoids. Materials and methods: An open Randomized comparative clinical study. The entire 40 patients were divided into two groups; Group-A: 20 patients- Application of Apamarg Pratisaaraniya Kshara, Group-B: 20 patients- Application of Kutaj Pratisaraniya Kshara. Observation and Results: According to the Chi-Square test the value obtained was 29.565 and p value was 0.0001 which is highly significantin group A. Conclusion: As per the complete analytical data and observation of the result found in the both group it has been revealed that patient to whom Apamarg Kshar was applied has the better result as compared to the application of Kutaja Kshara

String Fluid Cosmological Model with Magnetic Field in Bimetric Theory of Gravitation

In this paper, LRS Bianchi type I string fluid cosmological model with magnetic field in bimetric theory of gravitation is investigated by assuming barotropic equation of state for pressure and density and assuming the bulk viscosity to be inversely proportional to the scalar expansion. The source of energy momentum tensor is a bulk viscous fluid containing one dimensional string with electromagnetic field. The physical and geometrical properties of the model are discussed. The bulk viscosity affected the whole properties of the model

Risk-sensitive optimal control for Markov decision processes with monotone cost

The existence of an optimal feedback law is established for the risk-sensitive optimal control problem with denumerable state space. The main assumptions imposed are irreducibility and anear monotonicity condition on the one-step cost function. A solution can be found constructively using either value iteration or policy iteration under suitable conditions on initial feedback law

Non-Inflationary Bianchi Type VI0 Model in Rosen’s Bimetric Gravity

In this paper, we have present the solution of Bianchi type VI0 space-time by solving the Rosen’s field equations with massless scalar field φ and with constant scalar potential V(φ) for flat region. It is observed that the scalar field φ is an increasing function of time and affects the physical parameters of the model and leads to non-inflationary type solution of model, which contradicts the inflationary scenario. Other geometrical and physical properties of the model in relation to this non-inflationary model are also studied

PREVENTION AND MANAGEMENT OF GUDAGATA VIKARA (ANORECTAL DISORDERS)- AYURVEDIC PERSPECTIVE

Gudagata Vikara (Anorectal disorders) refers to ailments of the anus and/ or rectum. Gudagata Vikara includes; Arsha (Haemorrhoids), Bhagandara (Fistula in Ano), Parikartika (Fissure in Ano), Guda Kandu (Pruritus Ani), etc. These are some common disorders in human being. A study by Sharma et al. showed that Hemorrhoids (49%) and fistula-in-ano (27%) were commonest anorectal conditions, mostly affecting the age group 18-45 years. Apathya Ahara and Vihara leads to vitiation of Doshas causing Mandagni and vitiation of Apanavayu resulting in stagnation of Mala in Gudavali which leads to anorectal disorders. In present study a thorough and scientific review of Ahara (diet) and Vihara (lifestyle) has been carried out for the prevention and management of anorectal diseases. Materials and methods: Ayurvedic treaties, text books, Dissertation, Articles from PUBMED, SCOPUS, Google scholar, Mesh, Google search has been searched thoroughly related to the subject. Discussion: Gudagata Vikara, Anorectal Disorders, Ahara (Diet), Vihara (Lifestyle), Dinacharya, Ritucharya, Sadvritta has been discussed. Conclusions: Food articles mentioned in Ayurvedic text are effective in the management of Anorectal diseases. Lifestyle changes according to Dinacharya, Ritucharya and Sadavritta and following do’s and don’ts are effective in the management of Anorectal disease
