PRA: A PERSPECTIVE ON STRENGTHS, CURRENT LIMITATIONS, AND POSSIBLE IMPROVEMENTS

open access: yesNuclear Engineering and Technology, 2014
Probabilistic risk assessment (PRA) has been used in various technological fields to assist regulatory agencies, managerial decision makers, and systems designers in assessing and mitigating the risks inherent in these complex arrangements.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Shackle versus Savage: non-probabilistic alternatives to subjective probability theory in the 1950s [PDF]

open access: yes
G.L.S Shackle’s rejection of the probability tradition stemming from Knight's definition of uncertainty was a crucial episode in the development of modern decision theory.

Task-Structured Probabilistic I/O Automata [PDF]

open access: yes, 2009
"May 28, 2009."Modeling frameworks such as Probabilistic I/O Automata (PIOA) and Markov Decision Processes permit both probabilistic and nondeterministic choices. In order to use these frameworks to express claims about probabilities of events, one needs

Central Notion of Potential Theory: Balayage [PDF]

open access: yes, 2020
summary:Since the time of Poisson and Green it has been known that a charge placed inside a ball can be replaced by a charge distributed on the sphere $S$ in such a way that the potentials of the original charge and of the swept out charge on $S ...

A Flexible Bridge Rating Method Based on Analytical Evidential Reasoning and Monte Carlo Simulation

open access: yesAdvances in Civil Engineering, 2018
Several bridge inspection standards and condition assessment practices have been developed around the globe. Some practices employ four linguistic expressions to rate bridge elements while other practices use five or six, or adopt numerical ratings such ...

Five‐Year Outcomes of Laparoscopic Sphincter‐Preserving Surgery for Rectal Cancer: A Prospective Study in Elderly Vietnamese Patients

open access: yesAging and Cancer, EarlyView.
This prospective study demonstrates that laparoscopic sphincter‐preserving surgery is feasible for elderly patients. While overall survival reaches 70% at 5 years, advanced T‐stage and the omission of neoadjuvant therapy significantly drive recurrence, highlighting the need for personalized geriatric protocols despite logistical challenges.

Potential for the adaptation of probabilistic risk assessments by end-users and decision-makers [PDF]

open access: yes, 2008
In the area of risk assessment associated with ecotoxicological and plant protection products, probabilistic risk assessment (PRA) methodologies have been developed that enable quantification of variability and uncertainty.

Baseline Regional Cholinergic Denervation Predicts Cognitive Trajectories in Moderate Parkinson Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive decline is a disabling and variable feature of Parkinson disease (PD). While cholinergic system degeneration is linked to cognitive impairments in PD, most prior research reported cross‐sectional associations. We aimed to fill this gap by investigating whether baseline regional cerebral vesicular acetylcholine transporter ...
