Path analysis of Wiener Process

open access: yes, 2013
In this thesis we research and introduce several properties of paths of a Wiener process. At first we present a way to prove existence of a Wiener process and then we discuss its basic properties. The second chapter is devoted to analytical properties of

Degradation Modeling Using Stochastic Filtering for Systems under Imperfect Maintenance

open access: yesChemical Engineering Transactions, 2013
Wiener process with a linear drift has been extensively studied in degradation modeling, mainly due to the existence of an analytical expression of the first hitting time distribution which permits feasible mathematical developments.

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Evidence of introgression amid phylogenetic conflict in Brachyotum, a plant radiation from the Tropical Andes

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The species‐rich flora of Tropical Andes underwent multiple rapid and recent diversifications, yet resolving their evolutionary histories remains challenging despite increasing phylogenomic data. Here, we examined phylogenomic conflict in Brachyotum (Melastomataceae) to identify sources preventing its resolution.

On the Increments of Wiener and Related Processes

open access: yesThe Annals of Probability, 1982
Let $\{W(t), 0 \leq t < +\infty\}$ be a standard Wiener process and $0 < b_t \leq t$ be a nondecreasing function of $t$. The properties of the process $Y_1(t) = b^{-1/2}_t \sup_{0\leq s \leq t - b_t}(W(s + b_t) - W(s))$ are investigated. One of the results says that $\lim_{t\rightarrow\infty}(Y_1(t) - (2 \log tb^{-1}_t)^{1/2}) = 0$ a.s.

Two decades of resurrection studies: What have we learned about contemporary evolution of plant species?

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Global climate change has altered the eco‐evolutionary trajectories of plant species, leading to observed shifts in phenotypes, such as earlier flowering. However, disentangling the contributions of plasticity and adaptation to trait changes remains challenging.

The 9th International RASopathies Symposium

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The RASopathies are a group of congenital disorders with overlapping clinical manifestations that are caused by pathogenic germline or early somatic variants that result in the hyperactivation of the RAS/mitogen‐activated protein kinase (MAPK) signaling pathway.
