We show how the recently proposed effective theory for a Quantum Hall system at " paired states " filling ν = 1 [1][2], the twisted model (TM), well adapts to describe the phenomenology of Josephson Junction ladders (JJL) in the presence of impurities. In particular we focus on " closed " geometries which appear promising as " protected " qubits [3] for the… (More)

Liver metastases occur in 46-93% of patients with neuroendocrine neoplasms (NENs). Presence and extension of liver metastases are considered important prognostic factors, as they may significantly impair the patient's quality of life, because of either tumor bulk or hormonal hypersecretion. Therapies for NEN liver metastases include surgical resection,… (More)

We extend the construction of the effective conformal field theory for the Jain hierarchical fillings proposed in [7] to the description of a quantum Hall fluid at non standard fillings ν = m pm+2. The chiral primary fields are found by using a procedure which induces twisted boundary conditions on the m scalar fields; they appear as composite operators of… (More)

Some benign thyroid nodules are stationary in size over time while others grow progressively, indicating that there is a broad individual variability within benign nodules. To date, it is very difficult to predict if a benign thyroid nodule will grow in size and which will be its trend over time. While BRAF(V600E) is a highly specific marker of thyroid… (More)

Following a suggestion given in [1], we show how the U(1)⊗Z 2 symmetry of the fully frustrated XY (FFXY) model on a square lattice can be accounted for in the framework of the m-reduction procedure developed for a Quantum Hall system at " paired states " fillings ν = 1 [2, 3]. The resulting twisted conformal field theory (CFT) with central charge c = 2 is… (More)

We found some identities among η-functions of Dedekind, the characters of the W m algebra and those of the level 1 affine Lie algebra su(m) 1. They allow to characterize the Z m-orbifold of the m-component free bosons u(1) Km,p (our theory TM) as an extension of the full degenerate representations of W (m) 1+∞. In particular TM is proven to be a Γ 0… (More)

We argue that a system of interacting D-branes, generalizing a recent proposal, can be modelled as a Quantum Hall fluid. We show that tachyon condensation in such a system is equivalent to one particle tunnelling. In a conformal field theory effective description , that induces a transition from a theory with central charge c = 2 to a theory with c = 3/2,… (More)

CDKN1B encodes the cyclin-dependent kinase inhibitor p27/Kip1. CDKN1B mutations and polymorphisms are involved in tumorigenesis; specifically, the V109G single nucleotide polymorphism has been linked to different tumours with controversial results. Multiple endocrine neoplasia type 1 (MEN1) is a rare autosomal dominant syndrome, characterized by the… (More)

The Morita equivalence for field theories on noncommutative two-tori is analysed in detail for rational values of the noncommutativity parameter θ (in appropriate units): an isomor-phism is established between an abelian noncommutative field theory (NCFT) and a non-abelian theory of twisted fields on ordinary space. We focus on a particular conformal field… (More)

We show how the low-energy properties of the 2-leg XXZ spin-1/2 ladders with general anisotropy parameter ∆ on closed geometries can be accounted for in the framework of the m-reduction procedure developed in [1]. In the limit of quasi-decoupled chains, a conformal field theory (CFT) with central charge c = 2 is derived and its ability to describe the model… (More)
