LIDAR DATA RESOLUTION VERSUS HYDRO-MORPHOLOGICAL MODELS FOR FLOOD RISK ASSESSMENT
LiDAR topographical resolution hydro-morphological model
2014/4/24
Uncertainties in topographic data have a significant influence on hydro-morphological and hydraulic predictions and therefore on
flood risk assessment. In this work, the effects of topographic data ...
More than 23 million people are estimated to be living with HIV in Sub-Saharan Africa, concentrated primarily in East and Southern Africa (UNAIDS 2012). There are a number of noncompeting explanations...
Hungry horses could be more susceptible to contracting Hendra virus, according to the findings of a preliminary study into the effect of pasture availability on infection rates.
Comments on "Assessing future risk: quantifying the effects of sea level rise on storm surge risk for the southern shores of Long Island, New York," by Christine C. Shepard, et al (Natural Hazards, Vol. 60, No. 2, 727-745)
Comments Assessing future risk effects of sea level rise the southern shores of Long Island
2012/4/19
Tide gauge and satellite data indicate that the rate of sea level rise has not increased significantly in response to the last 3/4 century of CO2 emissions, so there is no reason to expect that it wil...
The photographs in this journal are educational and enlightening, explicit and enigmatic, moving and disturbing, beautiful and optimistic. This glimpse into a handful of lives paints a picture of life...

The University of Queensland scientists warn world's cloud forests are at risk of destruction
climate change habitat destruction

Many of the world's most rare and rich forests, the tropical montane cloud forests, could be all-but obliterated by 2080.
Geophagy: The Potential Risk of Sand Impaction.
On the Gerber-Shiu discounted penalty function for the ordinary renewal risk model with constant interest
Surplus immediately prior to ruin Deficit at ruin
2011/11/7
In this paper, we study the Gerber-Shiu discounted penalty function for the ordinary renewal risk model modified by the constant interest on the surplus. The time of ruin is analyzed in terms of it$\&...
Exponential and non-exponential upper bounds for the ruin probabilities for the double Cox processes risk models
Probability Double Cox processes Martingale method
2011/11/4
In this paper, we consider a general insurance risk model in which the premium income process and the claim process are based on Cox processes. Exponential upper bounds for ruin probabilities are obta...
Conditional Value-at-Risk for Random Immediate Reward Variables in Markov Decision Processes
Markov Decision Processes Conditional Value-at-Risk Risk Optimal Policy Inventory Model
2013/1/30
We consider risk minimization problems for Markov decision processes. From a standpoint of making the risk of random reward variable at each time as small as possible, a risk measure is introduced usi...
From Smile Asymptotics to Market Risk Measures
dynamic convex risk measures volatility skew stochastic volatility models indifference pricing backward stochastic differential equations
2011/10/9
Abstract: The left tail of the implied volatility skew, coming from quotes on out-of-the-money put options, can be thought to reflect the market's assessment of the risk of a huge drop in stock prices...
Quantum Financial Economics - Risk and Returns
Quantum Financial Economics Multifractal Self-Organized Criticality Quantum Chaotic Volatility
2011/8/17
Abstract: Financial volatility risk is addressed through a multiple round evolutionary quantum game equilibrium leading to Multifractal Self-Organized Criticality (MSOC) in the financial returns and i...
Biophysics of risk aversion based on neurotransmitter receptor theory
Biophysics of risk aversion neurotransmitter receptor theory Biological Physics
2011/8/2
Abstract: Decision under risk and uncertainty has been attracting attention in neuroeconomics and neuroendocrinology of decision-making. This paper demonstrated that the neurotransmitter receptor theo...
BSDEs in Utility Maximization with BMO Market Price of Risk
Quadratic BSDEs BMO Market Price of Risk Power Utility Maximization Dynamic Exponential Moments
2011/8/22
Abstract: This article studies quadratic semimartingale BSDEs arising in power utility maximization when the market price of risk is of BMO type. In a Brownian setting we provide a necessary and suffi...
