Mapping climate change in European temperature distributions

Environmental Research Letters, 2013
Climate change poses challenges for decision makers across society, not just in preparing for the climate of the future but even when planning for the climate of the present day.

Pattern of common hormonal disorders among patients with polycystic ovarian syndrome at a tertiary health facility in Nigeria

Nigerian Journal of Medicine, 2022
Background: Polycystic ovarian syndrome (PCOS) is a disease associated with multiple reproductive and metabolic endocrine disorders. It is associated with cardiometabolic complications with established morbidity and mortality. Aim: We studied the pattern

Nuclear Parton Distributions [PDF]

, 2016
We review a microscopic model of the nuclear parton distribution functions, which accounts for a number of nuclear effects including Fermi motion and nuclear binding, nuclear meson-exchange currents, off-shell corrections to bound nucleon distributions ...

Nonforward Parton Distributions [PDF]

, 1997
Applications of perturbative QCD to deeply virtual Compton scattering and hard exclusive electroproduction processes require a generalization of usual parton distributions for the case when long-distance information is accumulated in nonforward matrix ...

Analysis of pediatric fixation equipment with audio-video for chest radiography examinations

Jurnal Ilmiah SINERGI
Pediatric patients are generally uncooperative during radiology examinations. Radiographic images can become blurry due to movement. This will cause to repeat examinations, thereby significantly increasing radiation exposure, and it can pose significant ...

Asymptotic tail behavior of phase-type scale mixture distributions [PDF]

, 2015
We consider phase-type scale mixture distributions which correspond to distributions of a product of two independent random variables: a phase-type random variable $Y$ and a nonnegative but otherwise arbitrary random variable $S$ called the scaling ...

Are Parton Distributions Positive? [PDF]

, 1998
We show that the naive positivity conditions on polarized parton distributions which follow from their probabilistic interpretation in the naive parton model are reproduced in perturbative QCD at the leading log level if the quark and gluon distribution ...

Complex and distributional weights for sieved ultraspherical polynomials

International Journal of Mathematics and Mathematical Sciences, 1996
Contour integral and distributional orthogonality of sieved ultraspherical polynomials are established for values of the parameters outside the natural range of orthogonality by positive measures on the real line.

Demystifying generalized parton distributions [PDF]

, 2002
In this paper, I will explain in as simple and intuitive physical terms as possible what generalized parton distributions are, what new information about the structure of hadrons they convey and therefore what picture of the hadron will emerge.
