Pricing Compound and Extendible Options under Mixed Fractional Brownian Motion with Jumps
This study deals with the problem of pricing compound options when the underlying asset follows a mixed fractional Brownian motion with jumps. An analytic formula for compound options is derived under the risk neutral measure.

Objective We aimed to construct and evaluate the first laboratory‐based frailty index (FI‐Lab) for predicting adverse outcomes in systemic lupus erythematosus (SLE) and to compare its predictive ability to that of an existing clinical FI. Methods We used data from a single‐center prospective cohort of adult patients with SLE whose baseline visit ...

Since future universal access transceiver 2 (UAT2) mode automatic dependent surveillance-broadcast (ADS-B) devices for low-altitude aircraft surveillance would face overlapping messages in high-traffic scenarios, this study combines probabilistic ...

Properties of a Random Bipartite Geometric Associator Graph Inspired by Vehicular Networks
We consider a point process (PP) generated by superimposing an independent Poisson point process (PPP) on each line of a 2D Poisson line process (PLP). Termed PLP-PPP, this PP is suitable for modeling networks formed on an irregular collection of lines ...

High Health Care Utilization Preceding Diagnosis With Juvenile Idiopathic Arthritis
Objective Although early diagnosis improves long‐term outcomes, patients with juvenile idiopathic arthritis (JIA) often experience prolonged, circuitous paths to diagnosis. To inform diagnostic improvement, we sought to characterize health care utilization in the year preceding diagnosis. Methods We identified 10,021 patients with an incident diagnosis

Bayesian adaptation in Poisson cognitive systems
The aim of the study is to investigate the possibility of applying Bayesian adaptation algorithms to cognitive systems that perceive the Poisson process of external events.The method of research is the use of stochastic description and synthesis of ...

Linear Prediction of Sum of Two Poisson Process
Our goal from this work is to find the linear prediction of the sum of two Poisson process ) ( ) ( ) ( t Y t X t Z + = at the future time 0 ), ( ≥ + τ τ t Z and that is when we know the values of ) (t Z in the past time and the correlation ...

Second order corrections for the limits of normalized ruin times in the presence of heavy tails
In this paper we consider a compound Poisson risk model with regularly varying claim sizes. For this model in [4] an asymptotic formula for the finite time ruin probability is provided when the time is scaled by the mean excess function. In this paper
