Wavelet Analysis and Lognormal Distributions in GRBs [PDF]

, 1998
A wavelet analysis has been performed on 80 intense gamma-ray bursts GRBs) from the BATSE 3B catalog with durations longer than 2 seconds. The wavelet analysis applied novel features developed for edge detection in image processing and this filtering ...

A dose‐finding population pharmacokinetic/pharmacodynamic model of ginisortamab, an anti‐gremlin‐1 monoclonal antibody, in patients with solid tumours

British Journal of Clinical Pharmacology, EarlyView.
Aims Ginisortamab, a first‐in‐class human monoclonal antibody for the treatment of advanced solid tumours, binds to gremlin‐1 and restores bone morphogenetic protein signalling. We used pharmacokinetic/pharmacodynamic (PK/PD) modelling to characterize the relationship between ginisortamab dose and serum gremlin‐1 binding, using model‐based simulations ...

parfm : Parametric Frailty Models in R

Journal of Statistical Software, 2012
Frailty models are getting more and more popular to account for overdispersion and/or clustering in survival data. When the form of the baseline hazard is somehow known in advance, the parametric estimation approach can be used advantageously ...

Weibull or Lognormal Distribution to Characterize Fatigue Life Scatter – Which is More Suitable? – Continued

Fatigue of Aircraft Structures
This paper describes a study to determine whether fatigue test life scatter is best characterised by a Weibull or lognormal statistical distribution for a high strength steel used for landing gear structures. It is a response to “Face 2” of the ICAF 2017

Time Scales in Long GRBs

, 2001
We analyze a sample of bright long bursts and find that the pulses duration have a lognormal distribution while the intervals between pulses have an excess of long intervals (relative to lognormal distribution).

Cost‐effectiveness of DPYD genotyping prior to fluoropyrimidine‐based treatment for colorectal cancer in Wales

British Journal of Clinical Pharmacology, EarlyView.
Abstract Background Regulatory guidance in the United Kingdom advises DPYD genotyping prior to fluoropyrimidine‐based treatment. This economic evaluation estimated the costs and outcomes associated with DPYD screening prior to prescribing fluoropyrimidines for colorectal cancer in Wales and also considers additional variants to those included in ...

Anifrolumab Dose Regimen Selection for a Phase 3 Trial in Lupus Nephritis

Clinical Pharmacology &Therapeutics, EarlyView.
In patients with systemic lupus erythematosus (SLE), increased type I interferon signaling is associated with increased disease activity across organs, including in the kidney, which can cause lupus nephritis (LN). Anifrolumab, which abrogates type I interferon signaling, is an approved treatment for moderate to severe SLE.

The Lognormal Distribution Is Characterized by Its Integer Moments

Mathematics
The lognormal moment sequence is considered. Using the fractional moments technique, it is first proved that the lognormal has the largest differential entropy among the infinite positively supported probability densities with the same lognormal-moments.
