Effects of tree age and waterlogging duration on the form factors of eastern cottonwood (Populus deltoides Bartr. ex Marsh.)

open access: yesMetsanduslikud Uurimused, 2019
Stem form is the short name of the tree trunk shape. Stem form determines the quantity and quality of trunk volume, and affects forest timber volume and stand merchantable volume. Based on Populus deltoides Bartr. ex Marsh. in the Dongting Lake region of

S-Matrix of Nonlocal Scalar Quantum Field Theory in Basis Functions Representation

open access: yesParticles, 2019
Nonlocal quantum theory of a one-component scalar field in D-dimensional Euclidean spacetime is studied in representations of S -matrix theory for both polynomial and nonpolynomial interaction Lagrangians.

Efficacy and Safety Analysis of Roxarestat in Regulating Renal Anemia in Patients on Maintenance Hemodialysis

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Objective To compare the efficacy and safety of roxarestat versus recombinant human erythropoietin (rhEPO) in the management of renal anemia in patients undergoing maintenance hemodialysis. Methods This was a prospective, open‐label, randomized controlled trial.

The filling factor of the sEMG signal at low contraction forces in the quadriceps muscles is influenced by the thickness of the subcutaneous layer

open access: yesFrontiers in Physiology
Introduction: It has been shown that, for male subjects, the sEMG activity at low contraction forces is normally “pulsatile”, i.e., formed by a few large-amplitude MUPs, coming from the most superficial motor units.

Types of forest and timber reserves of plain beech stands in Ukraine

open access: yesНаукові праці Лісівничої академії наук України, 2019
Forest management on a typological basis foresees that forest site types and correct values of silvicultural indices of stands, including volumes of stands, reliably established during forest management activities allow planning appropriate forest ...

The form factor of the Fermi model spatial distribution

open access: yes, 1966
A useful analytic expression for the form factor [formula not included] of the Fermi distribution [formula not included] is derived. This expression consists of a simple term with elementary functions plus a rapidly convergent infinite series with terms ...

Therapeutic Apheresis for Intravenous Methylprednisolone‐Refractory Neuromyelitis Optica Spectrum Disorder: Clinical and Radiological Outcomes in a Single‐Center Case Series

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

Baryon form factors

open access: yes
We review the status of baryon form factors with a special focus on the nucleon electromagnetic form factors which are known best. First, we give an introduction into the dispersive analyses and emphasize the role of unitarity and analyticity in the construction of the isoscalar and isovector spectral functions.

Neutrino electromagnetic form factors [PDF]

open access: yesPhysical Review D, 1989
It has been suggested that an apparent correlation of the flux of detected solar neutrinos with solar activity is due to a neutrino magnetic moment. Here several terrestrial experiments that might observe the magnetic moment are considered, with emphasis on those employing reactor neutrinos.
