Let ∆ be an infinite, locally finite tree with more than two ends. Let Γ < Aut(∆) be an acylindrical uniform lattice. Then the boundary algebra AΓ = C(∂∆) Γ is a simple Cuntz-Krieger algebra whose K-theory is determined explicitly.

An apparatus for measuring parity-violating asymmetries in gamma-ray emission following polarized cold neutron capture was constructed as a 1/10th scale test of the design for the forthcoming −→n + p → d + γ experiment at LANSCE. The elements of the polarized neutron beam, including a polarized He neutron spin filter and a radio frequency neutron spin rotator, are described. Using CsI(Tl) detec...

The clinical and hematological course of β thalassemia intermedia is influenced by a number of genetic factors which play a role in increasing fetal haemoglobin levels. Several polymorphisms located in the promoters of β and γ globin gene are involved in influencing the disease severity. Our objective was to study the effect of cis-DNA haplotypes, motifs, or polymorphisms (Pre G γ globin gene h...

تالاسمی اینترمدیا به دسته ای از انواع تالاسمی ها اطلاق می شود که در آن شدت علائم بیماری از تالاسمی ماژور خفیف تر و از تالاسمی مینور شدیدتر می باشد. افزایش بیان هموگلوبین f یکی از فاکتورهایی است که باعث کاهش شدت بیماری تالاسمی ماژور و تبدیل آن به تالاسمی اینترمدیا می شود. در این تحقیق تغییرات نوکلئوتیدی مربوط به نواحی پروموتری ژن های a ، g گلوبین و نواحی تنظیمی بالادست و پایین دست خوشه ژنی بتا گ...

A hica is a highest weight, homogeneous, indecomposable, Calabi-Yau category of dimension 0. A hica has length l if its objects have Loewy length l and smaller. We classify hicas of length ≤ 4, up to equivalence, and study their properties. Over a fixed field F , we prove that hicas of length 4 are in one-one correspondence with bipartite graphs. We prove that an algebra AΓ controlling the hica...

A bstract We study the sensitivity of existing MEG data to lepton flavor violating axion-like particles produced through μ + → e aγ and estimate discovery potential for upcoming II experiment in this channel. The signal efficiency can be improved significantly if a new trigger implemented dedicated run with reduced beam intensity. This search would establish world leading measurement channel on...

Alzheimer's disease (AD) is the most common neurodegenerative disorder leading to dementia. Neuritic plaque formation is one of the pathological hallmarks of Alzheimer's disease. The central component of neuritic plaques is a small filamentous protein called amyloid β protein (Aβ)(1), which is derived from sequential proteolytic cleavage of the beta-amyloid precursor protein (APP) by β-secretas...

Let P be a polyhedron in H$ of finite volume such that the group Γ(P) generated by reflections in the faces of P is a discrete subgroup of IsomH$. Let Γ+(P) denote the subgroup of index 2 consisting entirely of orientation-preserving isometries so that Γ+(P) is a Kleinian group of finite covolume. Γ+(P) is called a polyhedral group. As discussed in [12] and [13] for example (see §2 below), asso...
