Approximations to the Probability Integral [PDF]

open access: yesNature, 1925
RECENT numbers of NATURE contain two interesting approximations to the probability integral, one by Prof. H. C. Plummer (October 25, 1924), and one by Mr. S. Krichewsky (January 10, 1925). A comparison made by the latter shows that of the two different formulae Prof.

On Low Treewidth Approximations of Conjunctive Queries [PDF]

open access: yes, 2012
We recently initiated the study of approximations of conjunctive queries within classes that admit tractable query evaluation (with respect to combined complexity).

Influenza Vaccination Responses in Disabled Stroke Patients: A Single‐Center Prospective Observational Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study aimed to investigate the immunological response to influenza vaccination, the incidence and severity of influenza infection, and the side effects of the vaccination in patients with ischemic stroke. Methods This prospective observational study was conducted between 2023 and 2024 at Ramathibodi Hospital.

A canonical entropy-based multiscale decomposition of functions

open access: yesJournal of Physics Communications
We introduce a canonical entropy-based multiscale decomposition of nonnegative $L^1$ functions that yields both physically meaningful approximations and an injective representation.

Risk of Non‐Arteritic Anterior Ischemic Optic Neuropathy in Idiopathic Intracranial Hypertension Patients Treated with GLP‐1 Receptor Agonists

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) have demonstrated significant weight‐reducing effects and may offer benefits in idiopathic intracranial hypertension (IIH); however, recent concerns about the risk of non‐arteritic anterior ischemic optic neuropathy (NAION) have emerged.

Strong Approximations in Probability and Statistics (eBook)

open access: yes, 2014
Strong Approximations in Probability and Statistics presents strong invariance type results for partial sums and empirical processes of independent and identically distributed random variables (IIDRV). This seven-chapter text emphasizes the applicability

Numerical Calculation of Finite-Time Ruin Probabilities in the Dual Risk Model

open access: yesRisks
In the dual risk model, while the ultimate ruin probability has an exact and straightforward formula, the mathematics becomes significantly more complex when considering a finite time horizon, and the literature on this topic is scarce.

A Computable Measure of Algorithmic Probability by Finite Approximations with an Application to Integer Sequences

open access: yesComplexity, 2017
Given the widespread use of lossless compression algorithms to approximate algorithmic (Kolmogorov-Chaitin) complexity and that, usually, generic lossless compression algorithms fall short at characterizing features other than statistical ones not ...

A stable iterative algorithm for evaluation of upper and lower approximations to ultimate ruin probabilities

open access: yesStatistica, 2007
In this contribution we present an iterative algorithm for the calculation of two-sided numerical approximations to the probability of ultimate ruin for the classical risk model, which can be directly used in the case of compounding assets as well ...

Formal properties of the probability of fixation: identities, inequalities and approximations

open access: yes, 2015
The formula for the probability of fixation of a new mutation is widely used in theoretical population genetics and molecular evolution. Here we derive a series of identities, inequalities and approximations for the exact probability of fixation of a new
