A Simulation and Experiment on the Optimization Design of an Air Outlet Structure for an Air-Assisted Sprayer

open access: yesAgriculture, 2023
In response to the issues of low-velocity zones and non-uniform jet velocity distribution in the airflow field of traditional air-assisted orchard sprayers, an arc-shaped air outlet suitable for axial-flow air-assisted systems is designed.

On strong uniform distribution IV

open access: yesJournal of Inequalities and Applications, 2001
This is an interesting contribution to metric uniform distribution and a continuation of earlier papers of the author on strong uniform distribution [Acta Arith. 56, 183--193 (1990; Zbl 0716.11036); Monatsh. Math. 132, 341--348 (2001; Zbl 1015.11037); Indag. Math., New Ser., 14, 233--240 (2003; Zbl 1054.11038)]. A typical result is the following. Let \(

Stability of second-order recurrences modulo pr

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
The concept of sequence stability generalizes the idea of uniform distribution. A sequence is p-stable if the set of residue frequencies of the sequence reduced modulo pr is eventually constant as a function of r.

Pre-Shaped Burst-Mode Hybrid MOPA Laser System at 10 kHz Pulse Frequency

open access: yesSensors, 2023
A temporal pre-shaped burst-mode hybrid fiber-bulk laser system was illustrated at a 10 kHz rate with a narrow spectral linewidth. A theoretical model was proposed to counteract the temporal profile distortion and compensate for the desired one, based on

Randomized Simplicial Hessian Update

open access: yesMathematics, 2021
Recently, a derivative-free optimization algorithm was proposed that utilizes a minimum Frobenius norm (MFN) Hessian update for estimating the second derivative information, which in turn is used for accelerating the search.

The gamma-uniform distribution and its applications [PDF]

open access: yes, 2012
summary:Up to present for modelling and analyzing of random phenomenons, some statistical distributions are proposed. This paper considers a new general class of distributions, generated from the logit of the gamma random variable. A special case of this

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...

Gaps in the sequence n2ϑ(mod1)

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1987
Let ϑ be an irrational number and let {t} denote the fractional part of t. For each N let I0,I1,…,IN be the intervals resulting from the partition of [0,1] by the points {k2ϑ}, k=1,2,…,N.

Mixture Representations for Generalized Burr, Snedecor–Fisher and Generalized Student Distributions with Related Results

open access: yesMathematics, 2023
In this paper, the representability of the generalized Student’s distribution as uniform and normal-scale mixtures is considered. It is also shown that the generalized Burr and the Snedecor–Fisher distributions can be represented as the scale mixtures of

Pediatric Idiopathic Multicentric Castleman Disease Is Often Severe But Responsive to Siltuximab

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Idiopathic multicentric Castleman disease (iMCD) is a potentially fatal immunologic disorder marked by widespread lymphadenopathy and inflammation. Siltuximab, an interleukin‐6 (IL‐6) inhibitor, is the only FDA‐approved treatment for adult patients with iMCD.
