In this exploratory study the spectrum of tetraquarks of type c \bar{c} s \bar{s} is calculated within a simple quark model with chromomagnetic interaction and effective quark masses extracted from meson and baryon spectra. It is tempting to see if this spectrum can accommodate the resonance Y(4140), observed by the CDF Collaboration, but not yet confirmed. The results seem to favor the JPC = 1++ sector where the coupling to the VV channel is nearly as small as that of X(3872), when described as a c \bar{c} q \bar{q} tetraquark. This suggests that Y(4140) could possibly be the strange partner of X(3872) in a tetraquark interpretation. However, the sector JPC = 0++ cannot entirely be excluded. This work questions the practice of extracting effective quark masses containing spin-independent contributions, from mesons and baryons, to be used in multiquark systems as well. [less ▲]

In this paper, we discuss methods to refine locally optimal solutions of sparse PCA. Starting from a local solution obtained by existing algorithms, these methods take advantage of convex relaxations of the sparse PCA problem to propose a refined solution that is still locally optimal but with a higher objective value.

Certaines espèces de pucerons et de fourmis entretiennent une relation bénéfique aux deux espèces que l'on nomme mutualisme. Le miellat produit par les pucerons est le ciment de cette relation. Alors que bon nombre d'ennemis naturels de pucerons se servent des odeurs de ces derniers pour localiser leur proie, aucune étude ne s'est actuellement intéressée à la potentialité des fourmis exploratrices à utiliser également les sémiochimiques de pucerons pour localiser ces derniers et établir ou non une relation de mutualisme. Cette étude avait donc pour objectif d'identifier et quantifier les odeurs émises par les pucerons et d'observer si celles-ci influencent le comportement de recherche de nourriture des fourmis exploratrices. Une analyse par SPME (Solid Phase Micro-extraction) a permis de mettre en évidence une différence en composition des odeurs pour du miellat provenant de deux espèces de pucerons, l'une étant myrmécophile (Aphis fabae) et l'autre non (Acyrthosiphon pisum). Les molécules volatiles du miellat d'A. fabae ont également été semi-quantifiées à l'aide de la thermodésorption. Les molécules volatiles principales de ce miellat sont le 3-méthyl-1-butanol, le 2-méthyl-1-butanol, le benzèneéthanol et le 3-méthylbutanal. La seconde partie de cette étude a permis de démontrer que les fourmis perçoivent les odeurs provenant des pucerons et plus particulièrement les odeurs de leur miellat. Des tests olfactométriques réalisés en milieu ouvert ont démontré que les fourmis s'orientent vers une plante infestée de pucerons. Ensuite, des études en milieu fermé ont démontré l'effet attractant du miellat envers les fourmis exploratrices. Celles-ci utilisent donc les sémiochimiques d'origine aphidienne pour s'orienter et rechercher une source de nourriture. Nous avons aussi observé que l'E-β-farnésène (EBF), phéromone d'alarme des pucerons, pouvait également jouer un rôle dans ce comportement de recherche. Enfin, nous avons démontré la capacité des fourmis exploratrices à discriminer une population de A. fabae d'une population de A. pisum sur base des odeurs émises par celles-ci. [less ▲]

This work considers the problem of fitting data on a Lie group by a coset of a compact subgroup. This problem can be seen as an extension of the problem of fitting affine subspaces in Rn to data which can be solved using principal component analysis. We show how the fitting problem can be reduced for biinvariant distances to a generalized mean calculation on an homogeneous space. For biinvariant Riemannian distances we provide an algorithm based on the Karcher mean gradient algorithm. We illustrate our approach by some examples on SO(n). [less ▲]

Strong cation exchange HPLC with the parallel ICP MS and electrospray hybrid linear ion trap quadrupole orbital trap mass spectrometry (ESI Orbitrap MS) detection was developed for the study of the metabolomic pattern of selenium in selenium-rich yeast. The mobile phase composition (gradient of ammonium formate in 20% methanol) was optimized to obtain separation in conditions guaranteeing the identical ICP MS sensitivity during the entire chromatographic run and the compatibility with electrospray ionization. Twenty seven Se-containing metabolites observed in the HPLC-ICP MS chromatogram were identified by ESI Orbitrap MS based on the Se isotopic pattern, the accurate molecular mass, and the multistage fragmentation patterns. The method allowed for the first time the correlation of the differences observed in HPLC-ICP MS chromatography of water extracts of Se-rich yeast samples from different manufacturers with the identity of the eluted compounds determined by ESI MS.

The objectives of this study were to determine the prevalence of sub-clinical diseases in poorly-performing Standardbred horses, compare their physiological response to exercise with control horses, and identify predictive parameters of poor-performance. Fifty horses underwent thorough clinical and ancillary examinations, including haematological and biochemical evaluation, Doppler echocardiography, standardised exercise tests (SETs) on both treadmill and racetrack, treadmill video-endoscopy and collection of respiratory fluids. Most of the poorly-performing horses exhibited many concomitant diseases. The most frequently diagnosed problems involved the lower and upper respiratory tract and the musculoskeletal system. Poor-performers had lower speeds at a blood lactate (LA) concentration of 4 mmol/L (VLA4) and a heart rate (HR) of 200 bpm (V200) on treadmill and racetrack, as well as lower values for haematological parameters, plasma angiotensin-converting enzyme and antioxidants, compared to control horses. Problems of the respiratory system were the most frequently diagnosed sub-clinical diseases affecting performance. SETs, together with some blood markers, may be useful as a non-specific diagnostic tool for early detection of diseases that may affect performance. [less ▲]
