We explicitly compute up to the fifth mass-level the partition function of ten-dimensional pure spinor worldsheet variables including the spin dependence. After adding the contribution from the (x, θ, pα) matter variables, we reproduce the massive superstring spectrum. Even though pure spinor variables are bosonic, the pure spinor partition function contains fermionic states which first appear ...
A much simpler proof of Theorem 1 from [1] is presented below, using notation and formulas numeration of [1]. The text below replaces the subsection General case from §4 of [1, p. 11]. General case. In the general case for some ω we are interested in a pairs (xi,xj) with dij = ωn. But there may exist a pairs (xk,xl) with dkl < ωn. Using the “cleaning” procedure [2] we show that the influence of...
BACKGROUND Heterozygous mutations in the CASK gene in Xp11.4 have been shown to be associated with a distinct brain malformation phenotype in females, including disproportionate pontine and cerebellar hypoplasia. METHODS The study characterised the CASK alteration in 20 new female patients by molecular karyotyping, fluorescence in situ hybridisation, sequencing, reverse transcriptase (RT) and...
BACKGROUND In Alzheimer disease (AD), tests of "first-order capabilities," such as reaction time or motor ability, might measure central nervous system integrity or disability more reliably than those of abstract, conceptual, or cognitive behavior. Saccade system impairments are present in AD, but their sensitivity or specificity remains unevaluated. OBJECTIVES To determine sensitivity and sp...
CONTEXT: Early motor impairments have been reported in children with neurodevelopmental disorders (NDD), but it is not clear if early detection of can identify at risk for NDD or how such might be detected. OBJECTIVE: To characterize function later diagnosed relative to typically developing normative data. DATA SOURCES: The Cumulative Index Nursing and Allied Health Literature, Embase, Medline,...
