The Signature of Galactic Tides in Local Group Dwarf Spheroidals

description: (Abridged) We use N-body simulations to explore the effects of tidal stripping on the structure of dwarf spheroidal galaxies (dSphs). We model dSphs as King spheres embedded in NFW dark halos that orbit the Galactic potential on eccentric orbits. We find that episodes of stellar mass loss remove the initial cutoff of the bound stellar core. Once equilibrium has been re-established the outer mass profile approaches a power-law in projection that is well described by a simple Plummer model. Tides also result in transient features in the outer density profile. As the system re-equilibrates, an outward-moving "excess" of stars is found at radii where the local crossing time exceeds the time elapsed since pericenter. If the orbit is known, these results provide a simple way to assess whether "breaks" and "bumps" in the profile of dSphs are actually tidal in origin. We apply this to the Sagittarius dwarf and, encouragingly, identify two features in the profile that may be traced to its two last pericentric passages. Applied to Leo I, we find that any tidal break would locate beyond the area surveyed by current data, casting doubt on recent claims of the detection of tidal debris around this galaxy. For Carina, the tidal break should occur at a radius twice farther than observed, suggesting that the outer excess of stars is not tidal in origin unless its orbit is in error. A similar comment applies to Sculptor, whose pericenter appears too large for Galactic tides to be important but whose outer profile, like that of Draco, nonetheless follows closely a Plummer-law. Fornax and Leo II show no sign of a power-law outer profile, suggesting that they have not suffered stellar tidal stripping. Published profiles for other, fainter Milky Way dSph companions do not extend sufficiently far to allow for conclusive assessment.

description: The maintenance of bacterial diversity at both species- and strain-levels is crucial for the sustainability of honey bee gut microbiota and host health. Periodic or random fluctuation in diet typically alters the metabolic niches available to gut microbes, thereby continuously reshaping bacterial diversity and interspecific interactions. It remains unclear how closely related bacteria adapt to these fluctuations and maintain coexistence within the bee gut. Here, we demonstrate that the five predominant Gilliamella species associated with Apis cerana, a widely distributed Asiatic honey bee, have diverged in carbohydrate metabolism to adapt to distinct nutrient niches driven by dietary fluctuation. Specifically, the glycan-specialists gain improved growth on a pollen-rich diet, but are overall inferior in competition to non-glycan-specialist on either a simple sugar or sugar-pollen diet, when co-inoculated in the bee host and transmitted across generations. Strikingly, despite of their disadvantage in a high-sugar condition, the glycan-specialists are found prevalent in natural A. cerana guts. We further reveal that these bacteria have adopted a life history strategy characterized by high biomass yield on a low-concentration sugar diet, allowing them to thrive under poor nutritional conditions, such as when the bee hosts undergo periodical starvation. Transcriptome analyses indicate that the divergence in life history strategies is attributed to gene expression programming rather than genetic variation. This study highlights the importance of integrative metabolic strategies in carbohydrate utilization, which facilitate the coexistence of closely related Gilliamella species in a changing bee gut environment.

description: We investigate the use of external time-dependent magnetic field for the control of the quantum states in a two-electron quantum ring. The hyperfine interaction of the confined electrons with surrounding nuclei couples the singlet state with the three triplet states. When the external magnetic field is changed, the singlet ground state becomes degenerate with the triplet states allowing singlet-triplet transitions. By choosing different speeds for the magnetic field switching the final quantum state of the system can be manipulated. We evaluate suitable magnetic field values and time scales for efficient quantum ring control.

description: Measuring the transport of electrons through a graphene sheet necessarily involves contacting it with metal electrodes. We study the adsorption of graphene on metal substrates using first-principles calculations at the level of density functional theory. The bonding of graphene to Al, Ag, Cu, Au and Pt(111) surfaces is so weak that its unique "ultrarelativistic" electronic structure is preserved. The interaction does, however, lead to a charge transfer that shifts the Fermi level by up to 0.5 eV with respect to the conical points. The crossover from p-type to n-type doping occurs for a metal with a work function ~5.4 eV, a value much larger than the work function of free-standing graphene, 4.5 eV. We develop a simple analytical model that describes the Fermi level shift in graphene in terms of the metal substrate work function. Graphene interacts with and binds more strongly to Co, Ni, Pd and Ti. This chemisorption involves hybridization between graphene $p_z$-states and metal d-states that opens a band gap in graphene. The graphene work function is as a result reduced considerably. In a current-in-plane device geometry this should lead to n-type doping of graphene.

description: We study the evolution of maximally symmetric $p$-branes with a $S_{p-i}\otimes \mathbbm{R}^i$ topology in flat expanding or collapsing homogeneous and isotropic universes with $N+1$ dimensions (with $N \ge 3$, $p < N$, $0 \le i < p$). We find the corresponding equations of motion and compute new analytical solutions for the trajectories in phase space. For a constant Hubble parameter, $H$, and $i=0$ we show that all initially static solutions with a physical radius below a certain critical value, $r_c^0$, are periodic while those with a larger initial radius become frozen in comoving coordinates at late times. We find a stationary solution with constant velocity and physical radius, $r_c$, and compute the root mean square velocity of the periodic $p$-brane solutions and the corresponding (average) equation of state of the $p$-brane gas. We also investigate the $p$-brane dynamics for $H \neq {\rm constant}$ in models where the evolution of the universe is driven by a perfect fluid with constant equation of state parameter, $w={\cal P}_p/ρ_p$, and show that a critical radius, $r_c$, can still be defined for $ -1 \le w < w_c$ with $w_c=(2-N)/N$. We further show that for $w \sim w_c$ the critical radius is given approximately by $r_c H \propto (w_c-w)^{γ_c}$ with $γ_c=-1/2$ ($r_c H \to \infty$ when $w \to w_c$). Finally, we discuss the impact that the large scale dynamics of the universe can have on the macroscopic evolution of very small loops.

description: We investigate LiVS2 and LiVSe2 with a triangular lattice as itinerant analogues of LiVO2, known for the formation of valence bond solid (VBS) state out of S = 1 frustrated magnet. LiVS2, which is located at the border between a metal and a correlated insulator, shows a first ordered transition from a paramagnetic metal to a VBS insulator at Tc ~ 305 K upon cooling. The presence of VBS state in the close vicinity of insulator-metal transition may suggest the importance of itinerancy in the formation of VBS state. We argue that the high temperature metallic phase of LiVS2 has a pseudo-gap, likely originating from the VBS fluctuation. LiVSe2 was found to be a paramagnetic metal down to 2 K.

Inherent rhythms of activity of the northern flying squirrel in relation to illumination and to lunar and solar photoperiodism
Creators: name: Radvanyi, Andrew
Publisher: name: University of British Columbia
Year: 2012

description: For more than three and one-half years a study was made of the amount of locomotor activity of the northern flying squirrel, Glaucomys sabrinus (Shaw). These nocturnal animals were studied in captivity under both natural climatic (outdoor) and controlled artificial (indoor) environmental conditions. Over a sixteen month period, 1285 observations were made under all kinds of weather upon the time at which flying squirrels became active. The average "awakening" time was 35.4 minutes after sunset. Spontaneous locomotor activity, of both individual and groups of flying squirrels, were recorded under natural climatic conditions by means of activity wheels, a treadle-board activity recorder, and an electronic vibration amplifier. Under these outside conditions an inverse relationship exists between the level of activity and the intensity of the nocturnal illumination. Locomotor activity was at a high level between the last and first quarter phases of the moon and declined markedly at full moon, or just afterwards. The relationship appeared to be unaltered by temperature, vapor pressure, the season, or the sex of the animal. The internal physiological "clock" governing this activity cycle persisted even after nine months under constant environmental conditions in which only the light was manipulated to produce 2-3 month periods of continuous light, continuous darkness, or light-dark periods in normal or reversed sequences. In later experiments manipulation of artificial moonlight was used to produce in the animals cycles of activity corresponding to lunar cycles of normal duration and lengthened cycles of 40-days duration or shortened cycles as brief as 7-days in duration. Under 8-hours light and 8-hours darkness (a 16-hour day instead of a 24-hour day), responsiveness differed markedly from the previous experiments i. e. the animals became almost as active under illumination as under darkness. Only after two months under these conditions did daylight activity begin to decline. Whether or not the animals could eventually adapt to a 16-hour day was not determined. This study reveals a series of inherent physiological controls within the animal which govern the level of the spontaneous activity under varying natural climatic conditions and under controlled artificial experimental conditions. The flying squirrel is sensitive to slight changes in light intensity during the dark periods. By observing the responses to varying environmental photoperiods, an attempt was made to understand the inherent rhythms of activity of this species--whether these should be neural, endocrinological, or both. Most nocturnal animals respond mainly to olfactory stimuli. The activity of the flying squirrel is shown by this study to be intimately determined by illumination.

description: In this work the flow field simulation inside the centrifugal compressor of a Micro Jet Engine (AMT Olympus) is described in detail. Firstly, the components of the corresponding compressor were measured, using a MITUTOYO Coordinate Measuring Machine (CMM), and then accurate digital models of the corresponding parts were produced, using the Computer Aided Design (CAD) software SolidWorks. The corresponding digital models were subsequently used to define the flow domain upstream, inside, and downstream the centrifugal compressor, taking into account the stationary and rotating parts, accordingly. A hybrid unstructured computational mesh was produced inside the stationary and rotating sub-domains, using the Beta CAE ANSA mesh generation software. The steady-state simulation of the corresponding flow filed was accomplished using the ANSYS CFX Computational Fluid Dynamics (CFD) solver, utilizing the Shear Stress Transport (SST) two-equation turbulence model. Specific attention was payed so that the inlet far-field boundary conditions and the outlet boundary conditions to be applied in adequate distances from the compressor. The simulation results revealed the details of the flow filed inside the centrifugal compressor, which will be used as a reference for a subsequent optimization of its geometry.
description: Στα πλαίσια της παρούσας Μεταπτυχιακής Διατριβής, αρχικά θα πραγματοποιηθεί κατασκευή του ψηφιακού μοντέλου του συμπιεστή (compressor) ενός μικρού στροβιλοαντιδραστήρα (turbojet), ο οποίος χρησιμοποιείται για την πρόωση μικρών μη-επανδρωμένων αεροσκαφών (UAVs) υψηλών επιδόσεων. Ο συμπιεστής περιλαμβάνει το τμήμα εισόδου (inlet), την πτερωτή (impeller), το πρόσθιο και οπίσθιο κέλυφος (front and rear casing) και την άτρακτο (shaft). Στο κέλυφος βρίσκονται ενσωματωμένα και τα σταθερά πτερύγια του διαχύτη (diffuser).
Από τα εν λόγω ψηφιακά μοντέλα θα παραχθούν τα αντίστοιχα μοντέλα του χωρίου ροής (flow domain), εντός του οποίου θα πραγματοποιηθεί η προσομοίωση της ροής του αέρα. Η προσομοίωση θα γίνει με τη χρήση του εμπορικού λογισμικού ANSYS CFX. Το χωρίο ροής εντός της πτερωτής θα είναι περιστρεφόμενο, ενώ τα υπόλοιπα θα είναι ακίνητα. Θα δημιουργηθεί το κατάλληλο υπολογιστικό πλέγμα για την διακριτοποίηση των εξισώσεων της ροής. Στη συνέχεια θα οριστούν οι κατάλληλες οριακές συνθήκες (εισόδου, εξόδου, στερεού τοιχώματος, ταχύτητα περιστροφής, διεπιφάνειες μεταξύ των σταθερών και περιστρεφόμενου τμήματος), καθώς και το μοντέλο επίλυσης (εξισώσεις RANS συμπιεστού συνεκτικού ρευστού, μοντέλο τύρβης SST, μόνιμο πεδίο ροής).
Μετά την προσομοίωση θα πραγματοποιηθεί επεξεργασία των αποτελεσμάτων, ώστε να φανούν τα προβλήματα της σχεδίασης και να προταθούν βελτιώσεις για την αύξηση της απόδοσης του εν λόγω συμπιεστή.

description: Background

Several mechanical thrombectomy (MT) devices have been designed with the goal of improving the recanalization rates of major intracranial artery occlusions.

Objective

In this single-center experience, we analyzed the acute ischemic stroke (AIS) treatment with Primary MT; safety and efficacy and clinical results in our patients with large vessel occlusion (LVO).

Methods

During a five-year period (from September 2011 to July 2016), out of 996 patients who presented to our center with a diagnosis of AIS, 113 (11.4%) patients (55 men and 58 women) underwent primary mechanical recanalization within three hours from onset of signs and symptoms for anterior and 12 hours for posterior circulation (with computer tomography angiography/perfusion ELVO). Successful recanalization (thrombolysis in cerebral infarction 2b–3), good outcome (modified Rankin scale score 0–2) and overall mortality rate, and symptomatic intracranial hemorrhage [sICH: parenchymal hematoma Type 1 or Type 2; National Institutes of Health Stroke Scale (NIHSS) score increment ≥4 points] were prospectively assessed.

description: Equilibrium properties of dilute binary fluid mixtures are studied in two-phase states on the basis of a Helmholtz free energy including the gradient free energy. The solute partitioning between gas and liquid (Henry's law) and the surface tension change $Δγ$ are discussed. A derivation of the Gibbs law $Δγ=-TΓ$ is given with $Γ$ being the surface adsorption. Calculated quantities include the derivatives $d T_c/dX$ and $d p_c/dX$ of the critical temperature and pressure with respect to the solute molar fraction $X$ and the temperature-derivative $(\p γ/\p T)_{{\rm cx},p}$ of the surface tension at fixed pressure $p$ on the coexistence surface. Here $(\p γ/\p T)_{{\rm cx},p}$ can be both positive and negative, depending on the solute molecular size and the solute-solvent interaction,and diverges on the azeptropic line. Explicit expressions are given for all these quantities in the van der Waals model.

Luttinger parameters and momentum distribution function for the half-filled spinless fermion Holstein model: A DMRG approach

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We reexamine the nature of the metallic phase of the one-dimensional half-filled Holstein model of spinless fermions. To this end we determine the Tomonaga-Luttinger-liquid correlation parameter $K_ρ$ by large-scale density-matrix renormalisation-group (DMRG) calculations, exploiting (i) the leading-order scaling relations between the ground-state energy and the single-particle excitation gap and (ii) the static charge structure factor in the long-wavelength limit. While both approaches give almost identical results for intermediate-to-large phonon frequencies, we find contrasting behaviour in the adiabatic regime: (i) $K_ρ>1$ (attractive) versus (ii) $K_ρ<1$ (repulsive). The latter result for the correlation exponent is corroborated by data obtained for the momentum distribution function $n(k)$, which puts the existence of an attractive metallic state in the spinless fermion Holstein model into question. We conclude that the scaling relation must be modified in the presence of electron-phonon interactions with noticeable retardation.

A mesoscopic ring as a XNOR gate: An exact result

subject: FOS: Physical sciences

description: We describe XNOR gate response in a mesoscopic ring threaded by a magnetic flux $ϕ$. The ring is attached symmetrically to two semi-infinite one-dimensional metallic electrodes and two gate voltages, viz, $V_a$ and $V_b$, are applied in one arm of the ring which are treated as the inputs of the XNOR gate. The calculations are based on the tight-binding model and the Green's function method, which numerically compute the conductance-energy and current-voltage characteristics as functions of the ring-to-electrode coupling strength, magnetic flux and gate voltages. Our theoretical study shows that, for a particular value of $ϕ$ ($=ϕ_0/2$) ($ϕ_0=ch/e$, the elementary flux-quantum), a high output current (1) (in the logical sense) appears if both the two inputs to the gate are the same, while if one but not both inputs are high (1), a low output current (0) results. It clearly exhibits the XNOR gate behavior and this aspect may be utilized in designing an electronic logic gate.
