INFLUENCE OF WORKING MEDIUM LEAKS ON THE POINT POSITION OF MAXIMUM COMPRESSION PRESSURE RISE RATE

open access: yesАвіаційно-космічна техніка та технологія, 2019
The article discusses the analysis of the parameters of the compression process, which is carried out according to the results of engine indication. The solution to this problem allows us to evaluate the technical condition of the cylinder-piston group ...

Braided Algebraic Quantum Groups

open access: yesMathematics
In this paper, we mainly introduce the notion of a braided algebraic group, which unifies the notions of a braided Hopf algebra with an integral, a Hopf group-coalgebra with a group-integral and an algebraic quantum group.

Kimmerle conjecture for the Held and O'Nan sporadic simple groups [PDF]

open access: yes, 2009
Using the Luthar--Passi method, we investigate the Zassenhaus and Kimmerle conjectures for normalized unit groups of integral group rings of the Held and O'Nan sporadic simple groups.

On the automorphism group of an integral group ring, I

open access: yesArchiv der Mathematik, 1977
Let G be a finite group, Z(G) denote the integral group ring ofG, and NA(G) denote the group of normalized automorphisms of Z(G). That is, NA(G) denotes the group of ring automorphismsfof Z(G) such thatf(g) has augmentation one for all g e G. As remarked in [1] and [5], little generality is lost by studying normalized automorphisms over arbitrary ...

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 ...

Structure of normal twisted group rings [PDF]

open access: yes, 1997
Let K(lambda)G be the twisted group ring of a group G over a commutative ring K with 1, and let lambda be a factor set (2-cocycle) of G over K. Suppose f:G —> U(K) is a map from G onto the group of units U(K) of the ring K satisfying f(1) = 1.

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.
