title: New exact results on density matrix for XXX spin chain
abstract: Using the fermionic basis, we obtain the expectation values of all \mathfrak {sl}}_{2}$sl2 invariant and C invariant local operators on 10 sites for the anisotropic six vertex model on a cylinder with generic Matsubara data. This is equivalent to the generalised Gibbs ensemble for the XXX spin chain. In the case when the \mathfrak {sl}}_{2}$sl2 and C symmetries are not broken this computation is equivalent to finding the entire density matrix up to 10 sites. As application, we compute the entanglement entropy without and with temperature, and compare the results with CFT predictions.

title: ExoMol molecular line lists XXX: a complete high accuracy line list for water
abstract: A new line list for H$_2${16}$O is presented. This line list, which is called POKAZATEL, includes transitions between rotation vibrational energy levels up to 41000 cm$ 1} in energy and is the most complete to date. The potential energy surface (PES) used for producing the line list was obtained by fitting a high quality ab initio PES to experimental energy levels with energies of 41000 cm$ 1} and for rotational excitations up to $J=5$ The final line list comprises all energy levels up to 41000 cm$ 1} and rotational angular momentum $J$ up to 72. An accurate ab initio dipole moment surface (DMS) was used for the calculation of line intensities and reproduces high precision experimental intensity data with an accuracy close to 1 The final line list uses empirical energy levels whenever they are available, to ensure that line positions are reproduced as accurately as possible. The POKAZATEL line list contains over 5 billion transitions and is available from the ExoMol website (www.exomol.com) and the CDS database.

title: Scalar Products in Twisted XXX Spin Chain. Determinant Representation
abstract: We consider XXX spin $1/2$ Heisenberg chain with non diagonal boundary conditions. We obtain a compact determinant representation for the scalar product of on shell and off shell Bethe vectors. In the particular case, we obtain a determinant representation for the norm of on shell Bethe vector and prove orthogonality of the on shell vectors corresponding to the different eigenvalues of the transfer matrix.

title: N Terminal Cu Binding Motifs (Xxx Zzz His, Xxx His) and Their Derivatives: Chemistry, Biology and Medicinal Applications.
abstract: Peptides and proteins with N terminal amino acid sequences NH2 Xxx His (XH) and NH2 Xxx Zzz His (XZH) form well established high affinity CuII complexes.  His (in serum albumin) and Gly His Lys, the wound healing factor. This opens a straightforward way to add a high affinity CuII binding site to almost any peptide or protein, by chemical or recombinant approaches. Thus, these motifs, NH2 Xxx Zzz His in particular, have been used to equip peptides and proteins with a multitude of functions based on the redox activity of Cu, including nuclease, protease, glycosidase, or oxygen activation properties, useful in anticancer or antimicrobial drugs. More recent research suggests novel biological functions, mainly based on the redox inertness of CuII in XZH, like PET imaging (with 64 Cu) chelation therapies (for instance in Alzheimer's disease and other types of neurodegeneration) antioxidant units, Cu transporters and activation of biological functions by strong CuII binding. This Review gives an overview of the chemical properties of Cu XH and XZH motifs and discusses the pros and cons of the vastly different biological applications, and how they could be improved depending on the application.

title: Modified Algebraic Bethe Ansatz: Twisted XXX Case
abstract: We prove the modified algebraic Bethe Ansatz characterization of the spectral problem for the closed XXX Heisenberg spin chain with an arbitrary twist and arbitrary positive (half) integer spin at each site of the chain. We provide two basis to characterize the spectral problem and two families of inhomogeneous Baxter T Q equations. The two families satisfy an inhomogeneous quantum Wronskian equation.

title: OPE for XXX
abstract: We explain a new method for finding the correlation functions for the XXX model which is based on the concepts of Operator Product Expansion of Quantum Field Theory on one hand and of fermionic bases for the XXX spin chain on the other. With this method, we are able to perform computations for up to 11 lattice sites. We show that these "experimental" data allow to guess exact formulae for the OPE coefficients.

title: A Spontaneous Pregnancy in a Patient with Turner Syndrome with 45,X/47,XXX Mosaicism: A Case Report and Review of the Literature.
abstract: Turner syndrome is a chromosomal abnormality, due to a total or partial loss of 1 of the X chromosomes and is mostly characterized clinically by short stature and primary ovarian insufficiency. Spontaneous pregnancies are rare (5% and of relatively high risk. This is 1 of few reported cases of spontaneous conception and favorable prognosis in a patient with Turner syndrome and a 45,X/47,XXX karyotype.  A 21 year old woman with Turner mosaicism (45,X/47,XXX) who had a full term, uncomplicated pregnancy after spontaneous conception, gave birth to a healthy female (46,XX) infant.  Spontaneous pregnancies in women with Turner syndrome are a rarity. Fertility preservation methods are being discussed. Due to the high reported incidence of neonatal, obstetric, maternal, and especially cardiovascular complications in those pregnancies, close monitoring is essential.

title: Planck intermediate results XXX. The angular power spectrum of polarized dust emission at intermediate and high Galactic latitudes
abstract: The polarized thermal emission from diffuse Galactic dust is the main foreground present in measurements of the polarization of the cosmic microwave background (CMB) at frequencies above 100 GHz. In this paper we exploit the uniqueness of the Planck HFI polarization data from 100 to 353 GHz to measure the polarized dust angular power spectra C_l^(EE) and C_l^(BB) over the multipole range 40 <l< 600 well away from the Galactic plane. These measurements will bring new insights into interstellar dust physics and allow a precise determination of the level of contamination for CMB polarization experiments. Despite the non Gaussian and anisotropic nature of Galactic dust, we show that general statistical properties of the emission can be characterized accurately over large fractions of the sky using angular power spectra. The polarization power spectra of the dust are well described by power laws in multipole, C_l l_a, with exponents a^(EE,BB) 2.42 0.02. The amplitudes of the polarization power spectra vary with the average brightness in a way similar to the intensity power spectra. The frequency dependence of the dust polarization spectra is consistent with modified blackbody emission with b_d 1.59 and T_d 19.6 K down to the lowest Planck HFI frequencies. We find a systematic difference between the amplitudes of the Galactic B and E modes, C_l^(BB)/C_l^(EE) 0.5. We verify that these general properties are preserved towards high Galactic latitudes with low dust column densities. We show that even in the faintest dust emitting regions there are no "clean" windows in the sky where primordial CMB B mode polarization measurements could be made without subtraction of foreground emission. Finally, we investigate the level of dust polarization in the specific field recently targeted by the BICEP2 experiment. Extrapolation of the Planck 353 GHz data to 150 GHz gives a dust power

title: The open XXX spin chain in the SoV framework: scalar product of separate states
abstract: We consider the XXX open spin 1/2 chain with the most general non diagonal boundary terms, that we solve by means of the quantum separation of variables (SoV) approach. We compute the scalar products of separate states, a class of states which notably contains all the eigenstates of the model. As usual for models solved by SoV, these scalar products can be expressed as some determinants with a non trivial dependance in terms of the inhomogeneity parameters that have to be introduced for the method to be applicable. We show that these determinants can be transformed into alternative ones in which the homogeneous limit can easily be taken. These new representations can be considered as generalizations of the well known determinant representation for the scalar products of the Bethe states of the periodic chain. In the particular case where a constraint is applied on the boundary parameters, such that the transfer matrix spectrum and eigenstates can be characterized in terms of polynomial solutions of a usual T Q equation, the scalar product that we compute here corresponds to the scalar product between two off shell Bethe type states. If in addition one of the states is an eigenstate, the determinant representation can be simplified, hence leading in this boundary case to direct analogues of algebraic Bethe ansatz determinant representations of the scalar products for the periodic chain.

title: Calculations with spectroscopic accuracy for energies, transition rates, hyperfine interaction constants, and Lande grfactors in nitrogen like Kr XXX
abstract: Extensive self consistent multi configuration Dirac Fock (MCDF) calculations and second order many body perturbation theory (MBPT) calculations are performed for the lowest 272 states belonging to the 2s22p3, 2s2p4, 2p5, 2s22p23l, and 2s2p33l (l=s, p, d) configurations of N like Kr XXX. Complete and consistent data sets of level energies, wavelengths, line strengths, oscillator strengths, lifetimes, AJ, BJ hyperfine interaction constants, Lande gJ factors, and electric dipole (E1) magnetic dipole (M1) electric quadrupole (E2) magnetic quadrupole (M2) transition rates among all these levels are given. The present MCDF and MBPT results are compared with each other and with other available experimental and theoretical results. The mean relative difference between our two sets of level energies is only about 0.003% for these 272 levels. The accuracy of the present calculations are high enough to facilitate identification of many observed spectral lines. These accurate data can be served as benchmark for other calculations and can be useful for fusion plasma research and astrophysical applications.
