MLL is fused to ENL or ELL in acute leukemias that contain t(l1; 191(q23;p131. Although ENL and ELL localize to chromosome 19, bands p13.3 and p13.1, respectively, these breakpoints are not always readily distinguished by standard cytogenetics. We therefore used reversa transcriptasepolymerase chain reaction (RT-PCR) assays to analyze 26 cases of childhood acute leukemia containing t(l1; 19) to...

We investigate to what extent homotopy invariant, excisive and matrix stable homology theories help one distinguish between the Leavitt path algebras $L(E)$ $L(F)$ of graphs $E$ $F$ over a commutative ground ring $\ell$. approach this by studying structure such under bivariant algebraic $K$-theory $kk$, which is universal theory with properties above. show that very mild assumptions on $\ell$, ...

Purpose—The primary goal of this study was to explore the effect of the language context on the socially withdrawn behaviors of school aged-children who are English Language Learners (ELLs) from middle to high SES backgrounds. This is one of the first studies to address the frequently confused concepts of shyness and unsociability as independent constructs within the ELL population. This study ...

Motivated by the first search for rare charged-current $B$ decay to four leptons, $\ell \bar{\nu}_\ell \ell^{(\prime)} \bar{\ell}^{(\prime)}$, we calculate amplitude with factorization methods. We obtain $B\to \gamma^*$ form factors, which depend on invariant masses of two lepton pairs, at leading power in an expansion $\Lambda_{\rm QCD}/m_b$ next-to-leading order $\alpha_s$, and $\mathcal{O}(\...

Let G be a group and $$\ell $$ commutative unital $$*$$ -ring with an element $$\lambda \in \ell such that + \lambda ^*= 1$$ . We introduce variants of hermitian bivariant K-theory for -algebras equipped G-action or G-grading. For any graph E finitely many vertices weight function $$\omega :E^1 \rightarrow G$$ , distinguished triangle $$L(E)=L_\ell (E)$$ in the G-graded category $$kk^h_{G_{{\te...

BACKGROUND The chromosomal translocation t(11;19)(q23;p13) with a breakpoint within subband 19p13.1 is found mainly in acute myeloid leukemia (AML) and results in the MLL-ELL fusion gene. Variations in the structure of MLL-ELL seem to influence the leukemogenic potency of the fusion in vivo and may lie behind differences in clinical features. The number of cases reported so far is very limited ...

The excitation of density and bending waves in Saturn's C ring by planetary oscillation modes presents a unique opportunity to learn about gas giant interiors rotation. However, theoretical complications related rapid differential rotation pose barrier the full utilization wave detections. We calculate using complete, non-perturbative treatment modelled after zonal winds self-consistently compu...
