Duroc and Iberian Pork Neural Network Classification by Visible and Near Infrared Reflectance Spectroscopy

a b s t r a c t Visible and near infrared reflectance spectroscopy (VIS/NIRS) was used to differentiate between Duroc and Iberian pork in the M. masseter. Samples of Duroc (n = 15) and Iberian (n = 15) pig muscles were scanned in the VIS/NIR region (350-2500 nm) using a portable spectral radiometer. Both mutual information and VIS/NIRS spectra characterization were developed to generate a ranking of variables and the data were then processed by artificial neural networks, establishing 1, 3, or 10 wavelengths as input variable for classifying between the pig breeds. The models correctly classified >70% of all problem assumptions, with a correct classification of >95% for the three-variable assumption using either mutual information ranking or VIS/NIRS spectra characterization. These results demonstrate the potential value of the VIS/ NIRS technique as an objective and rapid method for the authentication and identification of Duroc and Iberian pork

\u201cWhat is more important than love?\u201d. Parental attachment and romantic relationship in Italian emerging adulthood

Previous researches suggest that individuals with different attachment styles practice different styles of love, but these do not consider the role of trust, communication, and closeness to the father and mother separately. The main aim of this study was to evaluate the relationship and the impact of parental attachment, through the analysis of the participants\u2019 self-reported account and 1.

The 296 participants (19\u201329 years; 50.7% males) rated items of information on a questionnaire, regarding their perspective of their attachment to their mother/father and attitude toward love. Using a variable-centred approach and a person-centred approach, the results suggest that the respondents differed in levels of parental attachment or love styles and that the present parental attachment has a positive impact on their romantic relationship. It is possible to estimate romantic relationships and prevent manic relationships based on the individual\u2019s current perceptions of their attachment to the father or mother. The role of parents and paternal attachment, are still fundamental in Italian young adults. The role of communication with the mother, in particular, is controversial and should be further investigated

Parents’ Acute Illnesses, Hospitalizations, and Medication Changes During the Difficult First Year After Infant or Child NICU/PICU Death

Infant/child death is described as a most stressful life event; however, there are few reports of effects on parent physical health during the first year after the death. The study\u27s purpose is to examine the patterns of parent acute illnesses, hospitalizations, and medication changes over 1 to 13 months after neonatal intensive care unit (NICU) or pediatric intensive care unit (PICU) infant/child death in 3 racial/ethnic groups. METHODS: Secondary analyses were conducted with longitudinal data on parent health and functioning 1 to 13 months after infant/child NICU/PICU death. Parents (176 mothers, 73 fathers; 44% Hispanic, 35% black non-Hispanic, and 21% white non-Hispanic) of deceased infants/children were recruited from 4 children\u27s hospitals and state death records. Inclusion criteria-parents understood English or Spanish and had a deceased neonate/child ≤ 18. Exclusion criteria -deceased newborn from multiple gestation pregnancy, child in foster care, child\u27s injury due to suspected abuse, or parent death in illness/injury event. Parents reported numbers and types of acute illnesses, hospitalizations, and medication changes 1 to 13 months postdeath. RESULTS: Parents\u27 acute illnesses, hospitalizations, and medication changes were greatest between months 1 and 6, with relative quiescence in months 7 to 10, and an increase in months 11 to 13. Mothers (aged 32 ± 7.8 years) reported 300 acute illnesses (primarily colds/flu, headaches, anxiety/depression, and infections) and 89 hospitalizations (primarily infections, chest pain, and gastrointestinal problems). Fathers (aged 37 ± 8.8 years) reported 104 acute illnesses (colds/flu and headaches) and 9 hospitalizations. CONCLUSION: After infant/child NICU/PICU death, mothers had greater morbidity than fathers, with no significant differences by race/ethnicity. Parents\u27 health needs to be monitored in months 1 to 6 and months 11 to 13, and interventions targeted to parents in these months

Equilibrium Sampling From Nonequilibrium Dynamics

We present some applications of an Interacting Particle System (IPS) methodology to the field of Molecular Dynamics. This IPS method allows several simulations of a switched random process to keep closer to equilibrium at each time, thanks to a selection mechanism based on the relative virtual work induced on the system. It is therefore an efficient improvement of usual non-equilibrium simulations, which can be used to compute canonical averages, free energy differences, and typical transitions paths

Supersymmetric (non-)Abelian Bundles in the Type I and SO(32) Heterotic String

We discuss perturbative four-dimensional compactifications of both the SO(32) heterotic and the Type I string on smooth Calabi-Yau manifolds endowed with general non-abelian and abelian bundles. We analyse the generalized Green-Schwarz mechanism for multiple anomalous U(1) factors and derive the generically non-universal one-loop threshold corrections to the gauge kinetic function as well as the one-loop corrected Fayet-Iliopoulos terms. The latter can be interpreted as a stringy one-loop correction to the Donaldson-Uhlenbeck-Yau condition. Applying S-duality, for the Type I string we obtain the perturbative Pi-stability condition for non-abelian bundles on curved spaces. Some simple examples are given, and we qualitatively discuss some generic phenomenological aspects of this kind of string vacua. In particular, we point out that in principle an intermediate string scale scenario with TeV scale large extra dimensions might be possible for the heterotic string.Comment: LaTeX, 32 pages, v2: refs adde

Giant volume magnetostriction in the Y 2

An investigation of the Y2Fe17 compound belonging to the class of intermetallic alloys of rare-earth and 3d-transition metals is presented. The magnetization, magnetostriction, and thermal expansion of the Y2Fe17 single crystal were studied. The forced magnetostriction and magnetostriction constants were investigated in the temperature range of the magnetic ordering close to the room temperature. The giant field induced volume magnetostriction was discovered in the room temperature region in the magnetic field up to 1.2 T. The contributions of both anisotropic single-ion and isotropic pair exchange interactions to the volume magnetostriction and magnetostriction constants were determined. The experimental results were interpreted within the framework of the Standard Theory of Magnetostriction and the Landau thermodynamic theory. It was found out that the giant values of the volume magnetostriction were caused by the strong dependence of the 3d-electron Coulomb charge repulsion on the deformations and width of the 3d-electron energy band

Moduli Stabilisation and de Sitter String Vacua from Magnetised D7 Branes

Anomalous U(1)'s are ubiquitous in 4D chiral string models. Their presence crucially affects the process of moduli stabilisation and cannot be neglected in realistic set-ups. Their net effect in the 4D effective action is to induce a matter field dependence in the non-perturbative superpotential and a Fayet-Iliopoulos D-term. We study flux compactifications of IIB string theory in the presence of magnetised D7 branes. These give rise to anomalous U(1)'s that modify the standard moduli stabilisation procedure. We consider simple orientifold models to determine the matter field spectrum and the form of the effective field theory. We apply our results to one-modulus KKLT and multi-moduli large volume scenarios, in particular to the Calabi-Yau P^4_{[1,1,1,6,9]}. After stabilising the matter fields, the effective action for the Kahler moduli can acquire an extra positive term that can be used for de Sitter lifting with non-vanishing F- and D-terms. This provides an explicit realization of the D-term lifting proposal of hep-th/0309187.Comment: 35 pages, 1 figure. v2: Minor changes, references adde

D terms from D-branes, gauge invariance and moduli stabilization in flux compactifications

We elucidate the structure of D terms in N=1 orientifold compactifications with fluxes. As a case study, we consider a simple orbifold of the type-IIA theory with D6-branes at angles, O6-planes and general NSNS, RR and Scherk-Schwarz geometrical fluxes. We examine in detail the emergence of D terms, in their standard supergravity form, from an appropriate limit of the D-brane action. We derive the consistency conditions on gauged symmetries and general fluxes coming from brane-localized Bianchi identities, and their relation with the Freed-Witten anomaly. We extend our results to other N=1 compactifications and to non-geometrical fluxes. Finally, we discuss the possible role of U(1) D terms in the stabilization of the untwisted moduli from the closed string sector.Comment: 1+31 pages, 1 figur
