description: Crystalline Mn5Ge3 nanomagnets are formed inside a Mn-diluted Ge matrix using Mn ion implantation. A temperature-dependent memory effect and slow magnetic relaxation are observed below the superparamagnetic blocking temperature of Mn5Ge3. Our findings corroborate that the observed spin-glass-like features are caused by the size distribution of Mn5Ge3 nanomagnets, rather than by the inter-particle interaction through the Mn-diluted Ge matrix.

Clustering of variables around latent components: an application in consumer science

Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2008
Subjects: SECS-S/02 Statistica per la ricerca sperimentale e tecnologica

description: The present work proposes a method based on CLV (Clustering around Latent
Variables) for identifying groups of consumers in L-shape data. This kind of datastructure
is very common in consumer studies where a panel of consumers is asked to
assess the global liking of a certain number of products and then, preference scores are
arranged in a two-way table Y. External information on both products (physicalchemical
description or sensory attributes) and consumers (socio-demographic
background, purchase behaviours or consumption habits) may be available in a row
descriptor matrix X and in a column descriptor matrix Z respectively. The aim of this
method is to automatically provide a consumer segmentation where all the three
matrices play an active role in the classification, getting homogeneous groups from all
points of view: preference, products and consumer characteristics.
The proposed clustering method is illustrated on data from preference studies on food
products: juices based on berry fruits and traditional cheeses from Trentino. The
hedonic ratings given by the consumer panel on the products under study were
explained with respect to the product chemical compounds, sensory evaluation and
consumer socio-demographic information, purchase behaviour and consumption habits.

description: A class of algorithms in discrete space and continuous time for Brownian first passage time estimation is considered. A simple algorithm is derived that yields exact mean first passage times (MFPT) for linear potentials in one dimension, regardless of the lattice spacing. When applied to nonlinear potentials and/or higher spatial dimensions, numerical evidence suggests that this algorithm yields MFPT estimates that either outperform or rival Langevin-based (discrete time, continuous space) estimates.

description: The theory underlying neutrino oscillations has been described at length in the literature. The neutrino state produced by a weak decay is usually portrayed as a linear superposition of mass eigenstates with, variously, equal energies or equal momenta. We point out that such a description is incomplete, that in fact, the neutrino is entangled with the other particle or particles emerging from the decay. We offer an analysis of oscillation phenomena involving neutrinos (applying equally well to neutral mesons) that takes entanglement into account. Thereby we present a theoretically sound proof of the universal validity of the oscillation formulae ordinarily used. In so doing, we show that the departures from exponential decay reported by the GSI experiment cannot be attributed to neutrino mixing. Furthermore, we demonstrate that the `Mossbauer' neutrino oscillation experiment proposed by Raghavan, while technically challenging, is correctly and unambiguously describable by means of the usual oscillation formalae.

On the Recovery of the Star Formation History of the LMC from the VISTA Survey of the Magellanic System

description: The VISTA near infrared survey of the Magellanic System (VMC) will provide deep YJKs photometry reaching stars in the oldest turn-off point all over the Magellanic Clouds (MCs). As part of the preparation for the survey, we aim to access the accuracy in the Star Formation History (SFH) that can be expected from VMC data, in particular for the LMC. To this aim, we first simulate VMC images containing not only the LMC stellar populations but also the foreground MW stars and background galaxies. We perform aperture photometry over these simulated images, access the expected levels of photometric errors and incompleteness, and apply the classical technique of SFH-recovery based on the reconstruction of colour-magnitude diagrams (CMD) via the minimization of a chi-squared-like statistics. We then evaluate the expected errors in the recovered star formation rate as a function of stellar age, SFR(t), starting from models with a known Age--Metallicity Relation (AMR). It turns out that, for a given sky area, the random errors for ages older than ~0.4 Gyr seem to be independent of the crowding. For a spatial resolution of ~0.1 sqdeg, the random errors in SFR(t) will be below 20% for this wide range of ages. On the other hand, due to the smaller stellar statistics for stars younger than ~0.4 Gyr, the outer LMC regions will require larger areas to achieve the same level of accuracy in the SFR(t). If we consider the AMR as unknown, the SFH-recovery algorithm is able to accurately recover the input AMR, at the price of an increase of random errors in the SFR(t) by a factor of about 2.5. Experiments of SFH-recovery performed for varying distance modulus and reddening indicate that the propagation of the errors in these parameters in the SFR(t) implies systematic errors below 30%.

description: The human voice is a primary channel for emotional communication. It is often presumed that being able to recognize vocal emotions is important for everyday socio-emotional functioning, but evidence for this assumption remains scarce. Here, we examined relationships between vocal emotion recognition and socio-emotional adjustment in children. The sample included 141 6- to 8-year-old children, and the emotion tasks required them to categorize five emotions (anger, disgust, fear, happiness, sadness, plus neutrality), as conveyed by two types of vocal emotional cues: speech prosody and non-verbal vocalizations such as laughter. Socio-emotional adjustment was evaluated by the children's teachers using a multidimensional questionnaire of self-regulation and social behaviour. Based on frequentist and Bayesian analyses, we found that, for speech prosody, higher emotion recognition related to better general socio-emotional adjustment. This association remained significant even when the children's cognitive ability, age, sex and parental education were held constant. Follow-up analyses indicated that higher emotional prosody recognition was more robustly related to the socio-emotional dimensions of prosocial behaviour and cognitive and behavioural self-regulation. For emotion recognition in non-verbal vocalizations, no associations with socio-emotional adjustment were found. A similar null result was obtained for an additional task focused on facial emotion recognition. Overall, these results support the close link between children's emotional prosody recognition skills and their everyday social behaviour.
Sand sources, volumes and movement patterns on Wreck Beach, Vancouver, British Columbia
Creators: name: Pool, Meridith Ines
Publisher: name: University of British Columbia
Year: 2010

description: Along Wreck Beach the existing headland cliffs are eroding and receding under attack from terrestrial and marine agents. Valuable property is being lost and nearby structures endangered. Remedial measures were undertaken in the summer of 1974 to halt wave erosion along the cliff base. A rock groin and sand—gravel protective beach scheme was only partially success ful during the following year. To design an adequate protection system for the cliffs wind and wave effects need to be deter mined to fully understand the resulting sand movement patterns. Understanding the processes affecting Wreck Beach is the first step in controlling them. Methods used to investigate sand movement included field coverage of the study area in photographic form as well as instrument cross—sectioning over a two year period. These data were correlated with historical wind records and predictions from wave refraction diagrams to determine seasonal movement onto and off the beach face and the cyclic progression of sandbars in the longshore current direction. Annual sand trans port volumes, sand supply sources and amounts contributed are outlined. In designing a protection scheme in which longshore trans port requirements must be considered the information and calcu lations suggests that the Fraser River North Arm could amply provide the longshore transport supply requirements. However, some means in addition to the present natural processes must be available to bring this sand into a range where wind gen erated wave activity can incorporate it into the existing Wreck Beach system.
Cosmology of modified (but second order) gravity

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: This is a brief review of modified gravity cosmologies. Generically extensions of gravity action involve higher derivative terms, which can result in ghosts and instabilities. There are three ways to circumvent this: Chern-Simons terms, first order variational principle and nonlocality. We consider recent cosmological applications of these three classes of modified gravity models, in particular to the dark energy problem. The viable parameter spaces can be very efficiently constrained by taking into account cosmological data from all epochs in addition to Solar system tests and stability considerations. We make some new remarks concerning so called algebraic scalar-tensor theories, biscalar reformulation of nonlocal actions involving the inverse d'Alembertian, and a possible covariant formulation holographic cosmology with nonperturbative gravity.

description: We show theoretically that polariton pairs with a high degree of polarization entanglement can be produced through parametric scattering. We demonstrate that it can emerge in coincidence experiments, even at low excitation densities where the dynamics is dominated by incoherent photoluminesce. Our analysis is based on a microscopic quantum statistical approach that treats coherent and incoherent processes on an equal footing, thus allowing for a quantitative assessment of the amount of entanglement under realistic experimental conditions. This result puts forward the robustness of pair correlations in solid-state devices, even when noise dominates one-body correlations.

description: High redshift Type Ia supernovae (SNe Ia) are likely to be gravitationally lensed by dark matter haloes of galaxies in the foreground. Since SNe Ia have very small dispersion after light curve shape and colour corrections, their brightness can be used to measure properties of the dark matter haloes via gravitational magnification. We use observations of galaxies and SNe Ia within the Great Observatories Origins Deep Survey (GOODS) to measure the relation between galaxy luminosity and dark matter halo mass. The relation we investigate is a scaling law between velocity dispersion and galaxy luminosity in the B-band. The best-fitting values to this relation (velocity dispersion normalisation and exponent) are 136 km/s and 0.27. We find the velocity dispersion normalisation to be less than 190 km/s at the 95 per cent confidence level. This method provides an independent cross-check of measurements of dark matter halo properties from galaxy-galaxy lensing studies. Our results agree with the galaxy-galaxy lensing results, but have much larger uncertainties. The GOODS sample of SNe Ia is relatively small (we include 24 SNe) and the results therefore depend on individual SNe Ia. We have investigated a number of potential systematic effects. Light curve fitting, which affects the inferred brightness of the SNe Ia, appears to be the most important one. Results obtained using different light curve fitting procedures differ at the 68.3 per cent confidence level.

description: Buildings have a significant energy and environmental footprint. In Greece, there are about 4.1 million buildings, a quarter of which are exclusive-use nonresidential buildings. The aim of this work is to define the average construction and technical characteristics of the existing Hellenic nonresidential buildings, and to assess their energy performance, responding to the need for more information and insight on this sector. The work exploits data from about 2400 building energy audits that include general information as well as specific characteristics on the envelope construction and the electromechanical installations. The information were first screened by a data quality control and were then organized into 239 classes that correspond to the Hellenic nonresidential building typology, defined in terms of building use, vintage, and location. The analysis revealed that there is a great potential for upgrading the existing building stock, since only 4% of the audited buildings meet the current minimum thermal envelope code requirements and 15% are in compliance with code recommendations for the technical installations. Overall, only 1% of the buildings have fully compliant envelope and technical installations. The calculated total final energy use averages 217.5kWh/m2 for the entire NR sector, ranging between 89.0kWh/m2 and 530.0kWh/m2 among the different building uses.

description: We extend recent \textit{ab initio} calculations of the electronic band structure and the phonon dispersion relations of rhombohedral GeTe to calculations of the density of phonon states and the temperature dependent specific heat. The results are compared with measurements of the specific heat. It is discovered that the specific heat depends on hole concentration, not only in the very low temperature region (Sommerfeld term) but also at the maximum of $C_p/T^3$ (around 16 K). To explain this phenomenon, we have performed \textit{ab initio} lattice dynamical calculations for GeTe rendered metallic through the presence of a heavy hole concentration ($p$ $\sim$ 2$\times$ 10$^{21}$ cm$^{-3}$). They account for the increase observed in the maximum of $C_p/T^3$.

Genomic and non genomic effects of elevated concentration of anabolic steroids in human neuronal cells
Creators: name: Guarino, Goffredo <1979>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2008
Subjects: BIO/14 Farmacologia

description: Nandrolone and other anabolic androgenic steroids (AAS) at elevated concentration can alter
the expression and function of neurotransmitter systems and contribute to neuronal cell death.
This effect can explain the behavioural changes, drug dependence and neuro degeneration
observed in steroid abuser.
Nandrolone treatment (10-8M–10-5M) caused a time- and concentration-dependent
downregulation of mu opioid receptor (MOPr) transcripts in SH-SY5Y human neuroblastoma
cells. This effect was prevented by the androgen receptor (AR) antagonist hydroxyflutamide.
Receptor binding assays confirmed a decrease in MOPr of approximately 40% in nandrolonetreated
cells. Treatment with actinomycin D (10-5M), a transcription inhibitor, revealed that
nandrolone may regulate MOPr mRNA stability. In SH-SY5Y cells transfected with a human
MOPr luciferase promoter/reporter construct, nandrolone did not alter the rate of gene
transcription. These results suggest that nandrolone may regulate MOPr expression through
post-transcriptional mechanisms requiring the AR.
Cito-toxicity assays demonstrated a time- and concentration dependent decrease of
cells viability in SH-SY5Y cells exposed to steroids (10-6M–10-4M). This toxic effects is
independent of activation of AR and sigma-2 receptor. An increased of caspase-3 activity was
observed in cells treated with Nandrolone 10-6M for 48h.
Collectively, these data support the existence of two cellular mechanisms that might
explain the neurological syndromes observed in steroids abuser.
Falling Through the Cracks of Early Intervention and Prevention: Missed Smoking Cessation Referrals for Mothers in Early Head Start

description: Smoking rates have decreased overall but smoking during pregnancy remains a challenge with impacts to mother, child, and family. Referrals are a critical component in accessing cessation, yet research identifies several barriers to access. Early Head Start (EHS) is one avenue for referrals, and we wanted to understand which characteristics describe those who have received prenatal smoking cessation referrals from EHS. Methods. This project utilized secondary data from the EHS Family and Child Experiences Study (N = 144). We conducted three hierarchical logistic regressions based on the following characteristics pulled from the literature—demographics (e.g., race, ethnicity, age, education, marital status, and partner at home), smoking behavior, and accessibility (e.g., language, location, siblings in EHS, length of time (LOT) in EHS, and program type)— removing non-significant variables at each stage of the hierarchy. Results. Results indicated no significant differences in referral rates across demographics (ps > .32). Results also showed smoking during pregnancy predictive of referral receipt (OR = 10.35, p < .05). Lastly, results showed longer LOTs with EHS (OR = 4.41, p < .01) and siblings in EHS (OR = 10.98, p < .05) significantly associated with referral receipt. Discussion. We found equity among referrals, consistent with EHS’s anti-racist foundation. We found mothers only reporting smoking history were missed. Finally, we found when EHS knows about a pregnancy, either from early referral to EHS or from other children receiving services, the referral mechanism is most successful. Future work should include an emphasis on recruiting earlier in gestation.

description: Magnetic field estimates for nearby isolated neutron stars (INS) help to constrain both the characteristics of the population and the nature of their peculiar X-ray spectra. From a series of XMM-Newton observations of RX J2143.0+0654, we measure a spin-down rate of -4.6e-16 +/- 2.0e-16 Hz/s. While this does not allow a definitive measurement of the dipole magnetic field strength, fields of >1e14 G such as those inferred from the presence of a spectral absorption feature at 0.75keV are excluded. Instead, the field is most likely around 2e13 G, very similar to those of other INS. We not only suggest that this similarity most likely reflects the influence of magnetic field decay on this population, but also discuss a more speculative possibility that it results from peculiar conditions on the neutron-star surface. We find no evidence for spectral variability above the ~2% level. We confirm the presence of the 0.75-keV feature found earlier, and find tentative evidence for an additional absorption feature at 0.4 keV.

description: We present a study of the correlations between spectral, timing properties and mass accretion rate observed in X-rays from the Galactic Black Hole (BH) binary GRS 1915+105 during the transition between hard and soft states. We analyze all transition episodes from this source observed with RXTE, coordinated with Ryle Radio Telescope (RT) observations. We show that broad-band energy spectra of GRS 1915+105 during all these spectral states can be adequately presented by two Bulk Motion Comptonization (BMC) components: a hard component (BMC1, photon index Gamma_1=1.7-3.0) with turnover at high energies and soft thermal component (BMC2, Gamma_2=2.7-4.2) with characteristic color temperature <1 keV, and the redskewed iron line (LAOR) component. We also present observable correlations between the index and the normalization of the disk "seed" component. The use of "seed" disk normalization, which is presumably proportional to mass accretion rate in the disk, is crucial to establish the index saturation effect during the transition to the soft state. We discovered the photon index saturation of the soft and hard spectral components at values of 4.2 and 3 respectively. We present a physical model which explains the index-seed photon normalization correlations. We argue that the index saturation effect of the hard component (BMC1) is due to the soft photon Comptonization in the converging inflow close to BH and that of soft component is due to matter accumulation in the transition layer when mass accretion rate increases. In addition to our spectral model components we also find a strong feature of "blackbody-like" bump which color temperature is about 4.5 keV in eight observations of the intermediate and soft states. We discuss a possible origin of this "blackbody-like" emission.

description: Polynomials with values in an irreducible module of the symmetric group can be given the structure of a module for the rational Cherednik algebra, called a standard module. This algebra has one free parameter and is generated by differential-difference ("Dunkl") operators, multiplication by coordinate functions and the group algebra. By specializing Griffeth's (arXiv:0707.0251) results for the G(r,p,n) setting, one obtains norm formulae for symmetric and antisymmetric polynomials in the standard module. Such polynomials of minimum degree have norms which involve hook-lengths and generalize the norm of the alternating polynomial.

Strain rate behaviour of Saint-Jean-Vianney clay
Creators: name: Robertson, Peter K.
Publisher: name: University of British Columbia
Year: 2010

description: A series of constant rate of strain compression tests and creep rupture tests have been performed on undisturbed, isotropically consolidated quick clay from the Saint-Jean-Vianney region, Quebec Province, Canada. Both drained and undrained tests were performed in conventional triaxial equipment. Also included is the data obtained from a series of Ko consolidation tests performed by Dr.Y.P. Vaid at U.B.C. Saint-Jean-Vianney clay, hereafter referred to as S.J.V. clay, is a stiff, heavily overconsolidated, cemented clay, from the site of the Saint-Jean-Vianney slide of 1971. The testing of this, very stiff, cemented clay proved to be very difficult due to it's very stiff and brittle nature, combined with it's lenses of silt and fine sand. The consolidation testing showed that the preconsolidation pressure could vary from 7.5 Kg/cm² to 12 Kg/cm² depending on the strain rate of the test. Snead (1970) and Campanella and Vaid (1972) performed similar creep tests on a local clay, known as Haney clay. The analysis of the creep tests performed on S.J.V. clay showed similar relationships to those reported by Snead and, Campanella and Vaid, but because of the extremely stiff nature of this clay the scatter of the results was more than that reported for Haney clay. The testing indicated a possible stress-strain-strain rate relationship may exist along with a possible drained failure criterion. The results obtained from this research were very dependent on the bonding of this clay, and indicate that the bond strength appears to be a function of strain rate.

description: Pain is a health condition defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage. It can vary widely in intensity, quality, duration, and underlying pathophysiological mechanisms, leading to various forms of classification.

In terms of duration, pain can be classified as acute or chronic. Acute pain is short-term, typically related to injury or medical procedures, and usually resolves within 3 to 6 months. Chronic pain, on the other hand, is long-lasting, either continuous or intermittent, persisting beyond the expected time for tissue healing, and is often associated with psychological and pathological factors.

Pain management has long been a challenge for healthcare systems worldwide due to its significant impact on patients' quality of life and the costs involved in its treatment. In the search for innovative and therapeutic alternatives, in January 2025, the FDA approved suzetrigine for the treatment of acute pain. Suzetrigine works through a mechanism different from conventional analgesics by selectively inhibiting NaV1.8 sodium channels, which are responsible for transmitting pain signals.

This article reviews the available evidence on suzetrigine, including its pharmacological and pharmacokinetic properties, clinical trial results on efficacy and safety, and recommendations for its rational use.

description: The cytoplasmic accumulation and aggregates of TARDBP/TDP-43 (TAR DNA binding protein) are a pathological hallmark in amyotrophic lateral sclerosis and frontotemporal lobar degeneration. We previously reported that the primate specific cleavage of TARDBP accounts for its cytoplasmic mislocalization in the primate brains, prompting us to further investigate how the cytoplasmic TARDBP mediates neuropathology. Here we reported that cytoplasmic mutant TARDBP reduced SQSTM1 expression selectively in the monkey brain, when compared with the mouse brain, by inducing SQSTM1 mRNA instability via its binding to the unique 3ʹUTR sequence (GU/UG)n of the primate SQSTM1 transcript. Overexpression of SQSTM1 could diminish the cytoplasmic C-terminal TARDBP accumulation in the monkey brain by augmenting macroautophagy/autophagy activity. Our findings provide additional clues for the pathogenesis of cytoplasmic TARDBP and a potential therapy for mutant TARDBP-mediated neuropathology.
Supercell studies of the Fermi surface changes in the electron-doped superconductor LaFeAsO$_{1-x}$F$_x$

description: We study the changes in the Fermi surface with electron doping in the LaFeAsO$_{1-x}$F$_x$ superconductors with density-functional supercell calculations using the linearized augmented planewave (LAPW) method. The supercell calculations with explicit F substitution are compared with those obtained from the virtual crystal approximation (VCA) and from a simple rigid band shift. We find significant differences between the supercell results and those obtained from the rigid-band shift with electron doping, although quite remarkably the supercell results are in good agreement with the virtual crystal approximation (VCA) where the nuclear charges of the O atoms are slightly increased to mimic the addition of the extra electrons. With electron doping, the two cylindrical hole pockets along $Γ-Z$ shrink in size, and the third hole pocket around $Z$ disappears for an electron doping concentration in excess of about 7-8%, while the two elliptical electron cylinders along $M-A$ expand in size. The spin-orbit coupling does not affect the Fermi surface much except to somewhat reduce the size of the third hole pocket in the undoped case. We find that with the addition of the electrons the antiferromagnetic state becomes energetically less stable as compared to the nonmagnetic state, indicating that the electron doping may provide an extra degree of stability to the formation of the superconducting ground state.

Stellar Population and Kinematic Profiles in Spiral Bulges & Disks: Population Synthesis of Integrated Spectra

description: We present a detailed study of the stellar populations (SPs) and kinematics of the bulge and inner disk regions of eight nearby spiral galaxies (Sa-Sd) based on deep Gemini/GMOS data. The long-slit spectra extend to 1-2 disk scale lengths with S/N/Ang>=50. Several different model fitting techniques involving absorption-line indices and full spectrum fitting are explored and found to weigh age, metallicity, and abundance ratios differently. The SPs of spiral galaxies are not well matched by single episodes of star formation; representative SPs must involve average SP values integrated over the star formation history (SFH) of the galaxy. Our "full population synthesis" method is an optimised linear combination of model templates to the full spectrum with masking of regions poorly represented by the models. Our spiral bulges follow the same correlations of increasing light-weighted age and metallicity with central velocity dispersion as those of elliptical galaxies and early-type bulges found in other studies, but when SFHs more complex and realistic than a single burst are invoked, the trend with age is shallower and the scatter much reduced. In a mass-weighted context, all bulges are predominantly composed of old and metal-rich SPs. Bulge formation appears to dominated by early processes that are common to all spheroids, whether they currently reside in disks or not. While monolithic collapse cannot be ruled out in some cases, merging must be invoked to explain the SP gradients in most bulges. Further bulge growth via secular processes or "rejuvenated" star formation generally contributes minimally to the stellar mass budget. (Abridged)

No indication of f0(1370) in pi pi phase shift analyses

description: The scalar meson f_0(1370) - indicated in particular in the low energy p\bar p \to 3 body reactions - is a crucial element in certain schemes of the scalar meson spectroscopy including glueballs. The most definitive results can be obtained from elastic and inelastic pi pi phase shift analyses using the constraints from unitarity where the discrete ambiguities can be identified and resolved. We reconsider the phase shift analyses for pi^+ pi^- \to pi+ π-, pi^0 pi^0, K \bar K, eta eta. While a clear resonance signal for f_0(1500) in the resp. Argand diagrams is seen in all channels above a large ``background'' from f_0(600) there is no clear signal of a second resonance ``f_0(1370)'' in this mass range in any reaction, at the level of \sim 10% branching ratio into pi-pi.
