Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Shwachman–Diamond syndrome (SDS) is a rare autosomal recessive ribosomopathy characterized by bone marrow failure and multisystem involvement, with emerging evidence of associated neurocognitive impairment. Methods We conducted a retrospective study of 240 individuals with biallelic Shwachman–Bodian–Diamond syndrome (SBDS) mutations

Relativity without tears [PDF]
, 2008 Special relativity is no longer a new revolutionary theory but a firmly established cornerstone of modern physics. The teaching of special relativity, however, still follows its presentation as it unfolded historically, trying to convince the audience of

Quaternions and special relativity [PDF]
Journal of Mathematical Physics, 1996 We reformulate Special Relativity by a quaternionic algebra on reals. Using real linear quaternions, we show that previous difficulties, concerning the appropriate transformations on the 3+1 space–time, may be overcome. This implies that a complexified quaternionic version of Special Relativity is a choice and not a necessity.

Is Einstein’s Special Relativity Wrong?
SSRN Electronic Journal, 2020 Einstein’s special relativity is incomplete. It is vogue at the speed of the light and does not present a correct value of the momentum in the spacetime. Hence, all formulas that have been extracted in the last century should be reviewed.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Matter or geometry as fundamental in relativity theory: How not to teach special relativity [PDF]
, 2013 In this paper, I review a number of interpretational frameworks for relativistic phenomena like length contraction and relativity of simultaneity. Of central focus is the book Physical Relativity by Harvey Brown, where Brown advocates a view in which ...

Quantum Entropy and Special Relativity [PDF]
Physical Review Letters, 2002 We consider a single free spin 1/2 particle. The reduced density matrix for its spin is not covariant under Lorentz transformations. The spin entropy is not a relativistic scalar and has no invariant meaning.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
