description: The compactification of 6 dimensional Salam-Sezgin model in the presence of 3-form flux H is investigated. We find a torus topology for this compactification with two cusps which are the places of branes, while at the limit of large size L of the compact direction we also obtain sphere topology. This resembles the Randall-Sundrum I,II model. The branes at one of the cusps can be chosen to be 3- and 4-branes which fill our 4-dimensional space together with the fact that H=0 at this position restores the Lorentz symmetry. This compactification also provides an example for the so-called `time warp' solution, [0812.5107 [hep-th]]. According to a no-go theorem in $d\ne 6$, the time warp compactification violates the null energy condition. While the theorem is quiet for d=6, our model gives a time warp compactification which satisfies the null energy condition. We also derive the four dimensional effective Planck mass which is not obvious due to the time warp nature of the solution.

Search for Fermion-Pair Decays $Q\Qbar \to (\t\Wmp)(\tbar\Wpm)$ in Same-Charge Dilepton Events

description: We report the most restrictive direct limits on masses of fourth-generation down-type quarks $b^{\prime}$, and quark-like composite fermions ($B$ or $T_{5/3}$), decaying promptly to $t W^{\mp}$. We search for a significant excess of events with two same-charge leptons ($e$, $μ$), several hadronic jets, and missing transverse energy. An analysis of data from $p\overline{p}$ collisions with an integrated luminosity of 2.7 fb$^{-1}$ collected with the CDF II detector at Fermilab yields no evidence for such a signal, setting mass limits $m_{b^{\prime}}, m_{B} >$ 338 $\mathrm{GeV}/c^2$ and $m_{T_{5/3}} >$ 365 $\mathrm{GeV}/c^2$ at 95% confidence level.

Intergalactic Baryons in the Local Universe

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Simulations predict that shocks from large-scale structure formation and galactic winds have reduced the fraction of baryons in the warm, photoionized phase (the Lya forest) from nearly 100% in the early universe to less than 50% today. Some of the remaining baryons are predicted to lie in the warm-hot ionized medium (WHIM) phase at T=10^5-10^7 K, but the quantity remains a highly tunable parameter of the models. Modern UV spectrographs have provided unprecedented access to both the Lya forest and potential WHIM tracers at z~0, and several independent groups have constructed large catalogs of far-UV IGM absorbers along ~30 AGN sight lines. There is general agreement between the surveys that the warm, photoionized phase makes up ~30% of the baryon budget at z~0. Another ~10% can be accounted for in collapsed structures (stars, galaxies, etc.). However, interpretation of the ~100 high-ion (OVI, etc) absorbers at z<0.5 is more controversial. These species are readily created in the shocks expected to exist in the IGM, but they can also be created by photoionization and thus not represent WHIM material. Given several pieces of observational evidence and theoretical expectations, I argue that most of the observed OVI absorbers represent shocked gas at T~300,000 K rather than photoionized gas at T<30,000 K, and they are consequently valid tracers of the WHIM phase. Under this assumption, enriched gas at T=10^5-10^6 K can account for ~10% of the baryon budget at z<0.5, but this value may increase when bias and incompleteness are taken into account and help close the gap on the 50% of the baryons still "missing".

description: Free-floating substellar candidates with estimated theoretical masses of as low as ~5 Jupiter masses have been found in the ~3 Myr old sigma Orionis open cluster. As the overlap with the planetary mass domain increases, the question of how these objects form becomes important. The determination of their number density and whether a mass cut-off limit exists is crucial to understanding their formation. We propose to search for objects of yet lower masses in the cluster and determine the shape of the mass function at low mass. Using new- and (re-analysed) published IZJHKs[3.6]-[8.0]-band data of an area of 840 arcmin2, we performed a search for LT-type cluster member candidates in the magnitude range J=19.5-21.5 mag, based on their expected magnitudes and colours. Besides recovering the T type object S Ori 70 and two other known objects, we find three new cluster member candidates, S Ori 72-74, with J=21 mag and within 12 arcmin of the cluster centre. They have theoretical masses of 4 (-2,+3) M_Jup and are among the least massive free-floating objects detected by direct imaging outside the Solar System. The photometry in archival Spitzer [3.6]-[5.8]-band images infers that S Ori 72 is an L/T transition candidate and S Ori 73 a T-type candidate, following the expected cluster sequence in the mid-infrared. Finally, the L-type candidate S Ori 74 with lower quality photometry is located at 11.8 arcsec (~4250 AU) of a stellar member of sigma Orionis and could be a companion. After contaminant correction in the area complete to J=21.1 mag, we estimate that there remain between zero and two cluster members in the mass interval 6-4 M_Jup. Our result suggests a possible turnover in the substellar mass spectrum below ~6 Jupiter masses, which could be investigated further by wider and deeper photometric surveys.

description: We investigate the environment of the very low-luminosity object L1521F IRS using data from the Taurus Spitzer Legacy Survey. The MIPS 160 micron image shows both extended emission from the Taurus cloud as well as emission from multiple cold cores over a 1 X 2 deg region. Analysis shows that the cloud dust temperature is 14.2 +- 0.4 K and the extinction ratio is A_160/A_K = 0.010 +- 0.001 up to A_V ~ 4 mag. We find kappa_160 = 0.23 +- 0.046 cm^2/g for the specific opacity of the gas-dust mixture. Therefore, for dust in the Taurus cloud we find the 160 um opacity is significantly higher than that measured for the diffuse ISM, but not too different from dense cores, even at modest extinction values. Furthermore, the 160 um image shows features that do not appear in the IRAS 100 um image. We identify six regions as cold cores, i.e. colder than 14.2 K, all of which have counterparts in extinction maps or C18O maps. We compare the effects of L1521F IRS on its natal core and find there is no evidence for dust heating at 160 or 100 um by the embedded source. From the infrared luminosity L_TIR = 0.024 Lo we find L_bol = 0.034 - 0.046L_o, thus confirming the source's low-luminosity. Comparison of L1521F IRS with theoretical simulations for the very early phases of star formation appears to rule out the first core collapse phase. The evolutionary state appears similar to or younger than the class 0 phase, and the estimated mass is likely to be substellar.

description: The unrestrainable evolution of medical science and technology is drastically changing health-care, enabling new medical procedures and remedies, which are increasingly intertwined with moral principles. Although a uniform European approach on assisted suicide is lacking, a common trend is developing: the boundary between euthanasia, assisted suicide and end-of-life care and the frontiers of legitimate medicine are becoming increasingly blurred. In Italy, a ruling of the Constitutional Court, no. 242/2019, declared the partial unconstitutionality of article 580 of the Italian Criminal Code, which prohibited assistance in suicide. Specifically, article 580 excluded the criminal liability for the person who, in the manner provided for in Articles 1 and 2 of the law 22 December 2017, no. 219, “facilitates the execution of intention of suicide, autonomously and freely formed, of one person kept alive by life-sustaining treatments and suffering from an irreversible pathology, source of physical or psychological suffering that he/she deems intolerable, but fully capable of making free aware decisions, provided that such conditions and methods of execution have been verified by a public structure of the national health service, following the opinion of the territorially competent ethics committee.” The present paper analyzes the legal regime of assisted suicide in Italy, the role of the rule of law, and the crucial boundary between the branches of government with regard to this delicate issue, and investigates current legal challenges and potential future legal tracks.

description: Excited states in the extremely neutron-deficient nucleus, 180Pb, have been identified for the first time using the JUROGAM II array in conjunction with the RITU recoil separator at the Accelerator Laboratory of the University of Jyvaskyla. This study lies at the limit of what is presently achievable with in-beam spectroscopy, with an estimated cross-section of only 10 nb for the 92Mo(90Zr,2n)180Pb reaction. A continuation of the trend observed in 182Pb and 184Pb is seen, where the prolate minimum continues to rise beyond the N=104 mid-shell with respect to the spherical ground state. Beyond mean-field calculations are in reasonable correspondence with the trends deduced from experiment.

Teledentistry perceptions and practices among British Columbia dentists
Creators: name: Wong, Michael Stephen
Publisher: name: University of British Columbia
Year: 2023

description: Purpose: This study aims to understand what knowledge dentists have about teledentistry, the attitudes they had towards teledentistry, if/how they implemented teledentistry in their practices during COVID-19, and if clinicians intend to continue to use teledentistry following the COVID-19 pandemic. Methods: A 21 item online anonymous survey assessing the knowledge, attitudes, and practice of teledentistry was developed and distributed to dentists in British Columbia between July 18, 2022, to October 24, 2022 through e-mail. Descriptive statistics, bivariate chi-square analysis, and binary logistic regression were performed. Our sample size calculation was 660. P-value was set at p<0.001. Results:. Of the surveys returned, 198 surveys met the inclusion criteria and were included in data analysis. The majority of dentists agreed on the benefits of teledentistry. Just over half (53.6%) of respondents had used a form of teledentistry at the time of survey. Over three quarters (75.8%) of the surveyed dentists had no prior training in teledentistry. Practitioner comfort level was found to be a predictor for future teledentistry use amongst dentists. Conclusion: Respondents in this study were unprepared for the provision of care using teledentistry at the start of the COVID-19 pandemic. Practitioner comfort level was found to be a determinant for continued use of teledentistry following the pandemic. Education in teledentistry may improve practitioner comfort and improve the widespread implementation of teledentistry in the dental profession.

description: In this study we present simultaneous low-resolution longitudinal magnetic field measurements and high-resolution spectroscopic observations of the cool single giant FK Com. The variation of the magnetic field over the rotational period of 2.4 days is compared with the starspot location obtained using Doppler imaging techniques, V-band photometry and V-I colours. The chromospheric activity is studied simultaneously with the photospheric activity using high resolution observations of the Halpha, Hbeta and Hgamma line profiles. Both the maximum (272 +/- 24 G) and minimum (60 +/- 17 G) in the mean longitudinal magnetic field, , are detected close to the phases where cool spots appear on the stellar surface. A possible explanation for such a behaviour is that the active regions at the two longitudes separated by 0.2 in phase have opposite polarities.

description: Atomic (qubit) and optical or microwave (modal) phase-estimation protocols are placed on the same footing in terms of quantum-circuit diagrams. Circuit equivalences are used to demonstrate the equivalence of protocols that achieve the Heisenberg limit by employing entangled superpositions of Fock states, such as N00N states. The key equivalences are those that disentangle a circuit so that phase information is written exclusively on a mode or modes or on a qubit. The Fock-state-superposition phase-estimation circuits are converted to use entangled coherent-state superpositions; the resulting protocols are more amenable to realization in the lab, particularly in a qubit/cavity setting at microwave frequencies.

Year: 2009
Subjects: subject: Atomic Physics (physics.atom-ph)

description: Classical collisions with an ideal gas generate non-Maxwellian distribution functions for a single ion in a radio frequency ion trap. The distributions have power-law tails whose exponent depends on the ratio of buffer gas to ion mass. This provides a statistical explanation for the previously observed transition from cooling to heating. Monte Carlo results approximate a Tsallis distribution over a wide range of parameters and have ab initio agreement with experiment.
Condensation in Temporally Correlated Zero-Range Dynamics

description: Condensation phenomena in non-equilibrium systems have been modeled by the zero-range process, which is a model of particles hopping between boxes with Markovian dynamics. In many cases, memory effects in the dynamics cannot be neglected. In an attempt to understand the possible impact of temporal correlations on the condensate, we introduce and study a process with non-Markovian zero-range dynamics. We find that memory effects have significant impact on the condensation scenario. Specifically, two main results are found: (1) In mean-field dynamics, the steady state corresponds to that of a Markovian ZRP, but with modified hopping rates which can affect condensation, and (2) for nearest-neighbor hopping in one dimension, the condensate occupies two adjacent sites on the lattice and drifts with a finite velocity. The validity of these results in a more general context is discussed.

description: Let K be a function field with constant field k and let "infinity" be a fixed place of K. Let C be the Dedekind domain consisting of all those elements of K which are integral outside "infinity". The group G=GL_2(C) is important for a number of reasons. For example, when k is finite, it plays a central role in the theory of Drinfeld modular curves. Many properties follow from the action of G on its associated Bruhat-Tits tree, T. Classical Bass-Serre theory shows how a presentation for G can be derived from the structure of the quotient graph (or fundamental domain) G\T. The shape of this quotient graph (for any G) is described in a fundamental result of Serre. However there are very few known examples for which a detailed description of G\T is known. (One such is the rational case, C=k[t], i.e. when K has genus zero and "infinity" has degree one.) In this paper we give a precise description of G\T for the case where the genus of K is zero, K has no places of degree one and "infinity" has degree two. Among the known examples a new feature here is the appearance of vertex stabilizer subgroups (of G) which are of quaternionic type.

title: Home visiting to support early childhood care and development: challenges and opportunities in sub-Saharan Africa
Creators: name: Ebrahim, Hasina Banu
Publisher: name: Norland
Year: 2023

description: The global pandemic has highlighted the inadequacies of centre-based provision for children in sub-Saharan Africa and beyond. Most young children in sub-Saharan Africa reside with families, and delivery of services in the home is becoming increasingly important. In pre-pandemic times, home visiting programmes surfaced as a modality to support young children and families in disadvantaged contexts. In current times, this modality continues to be underdeveloped and trapped in the broader challenges of making early childhood care and education public provision. The aim of this paper is to engage with challenges and opportunities in home visiting directed at supporting early childhood care and education. In so doing, a call is made for more structured government support to enable the development of high-quality home visiting programmes.

description: Home-based childcare, or family day care as it is also known, plays an important role in supporting young children’s care and education. It offers early learning opportunities as well as crucial childcare support for working parents, particularly for those with children in the early years. This paper reviews research undertaken over a decade, including the author’s own work and that of other researchers, on the role of home-based childcare in delivering early care and education. Evidence from research in the UK and internationally has consistently shown the positive associations between quality home-based day-care provision and young children’s development (Ang, 2019; Ang et al., 2017; Fauth et al., 2013). Research has also indicated that professional childcare educators working in a home-based setting play a vital role in building strong partnerships with parents and families by offering added social and family support (Garrity and McGrath, 2011). This paper argues that quality home-based childcare, as shown through the evidence base, is an important and unique model of childcare provision that can have a beneficial impact on parents and families as well as on young children’s care, education and overall development.

description: We present an analysis of results on absorption from Ca II, Ca I, K I, and the molecules CH+, CH, C2, and CN that probes gas interacting with the supernova remnant IC443. The eleven directions sample material across the visible nebula and beyond its eastern edge. Most of the neutral material, including the diatomic molecules, is associated with the ambient cloud detected via H I and CO emission. Analysis of excitation and chemistry yields gas densities that are typical of diffuse molecular gas. The low density gas probed by Ca II extends over a large range in velocities, from -120 to +80 km/s in the most extreme cases. This gas is distributed among several velocity components, unlike the situation for the shocked molecular clumps, whose emission occurs over much the same range but as very broad features. The extent of the high-velocity absorption suggests a shock velocity of 100 km/s for the expanding nebula.

description: We report the performance of two prototype TeO2 macrobolometers, operated at ~25 mK, able to identify events due to energy deposited at the detector surface. This capability is obtained by thermally coupling thin Ge active layers to the main energy absorber of the bolometer, and is demonstrated by irradiating the detectors with alpha particles. The temperature variations of the main absorber and of the active layer are measured independently with doped Ge thermistors. These results show clearly that an intrinsic limitation of monolithic low temperature calorimeters, e.g., the impossibility to give information about event position, can be efficiently overcome using composite structures.
Mesolimbic dopaminergic modulation of cue-guided risk-reward decision making
Creators: name: Schofield-Lewis, Shayden
Publisher: name: University of British Columbia
Year: 2023

description: In naturalistic decision making, we are often presented with options that provide a small reward with a high degree of certainty, or riskier options with a larger reward at the cost of higher uncertainty. Human models of decision making often provide participants with external cues to guide subsequent decisions, however in rodent models of decision making it is common for the animal to develop an internal model of decision making in response to previous choice outcomes. To bridge the gap between human and rodent models of externally guided decision making, our lab has developed the “blackjack task”, where animals listen for an external auditory cue which signals the probability of a larger, riskier reward being delivered with favourable odds (50%) or unfavourable odds (12.5%) in comparison to a smaller reward delivered with 100% certainty. Both human and rodent studies have verified the importance of dopamine (DA) transmission in nucleus accumbens (NAc) and its core and shell subregions in the modulation of such risk-reward decision making. Here, we further clarify this role by delivering intracranial infusions of D1 or D2 antagonists directly into the NAc core or shell. It was found that D2 but surprisingly not D1 receptors modulate risk-reward decision making differentially in the NAc core versus NAc shell. D2 blockade in the NAc core blunted risky choice, while D2 blockade in the NAc shell heightened risky choice. These data contribute to the understanding that externally guided risk-reward decision making is affected differently by DA receptors, and that this effect is also subregion dependent.

description: The SARS-CoV-2, a positive-sense single-stranded RNA Coronavirus, is a global threat to human health. Thus, understanding its life cycle mechanistically would be important to facilitate the design of antiviral drugs. A key aspect of viral progression is the synthesis of viral proteins by the ribosome of the human host. In Coronaviruses, this process is regulated by the viral 5ʹ and 3ʹ untranslated regions (UTRs), but the precise regulatory mechanism has not yet been well understood. In particular, the 5ʹ-UTR of the viral genome is most likely involved in translation initiation of viral proteins. Here, we performed inline probing and RNase V1 probing to establish a model of the secondary structure of SARS-CoV-2 5ʹ-UTR. We found that the 5ʹ-UTR contains stable structures including a very stable four-way junction close to the AUG start codon. Sequence alignment analysis of SARS-CoV-2 variants 5ʹ-UTRs revealed a highly conserved structure with few co-variations that confirmed our secondary structure model based on probing experiments.

description: We study a ring cavity filled with a slab of a right-handed material and a slab of a left-handed material. Both layers are assumed to be nonlinear Kerr media. First, we derive a model for the propagation of light in a left-handed material. By constructing a mean-field model, we show that the sign of diffraction can be made either positive or negative in this resonator, depending on the thicknesses of the layers. Subsequently, we demonstrate that the dynamical behavior of the modulation instability is strongly affected by the sign of the diffraction coefficient. Finally, we study the dissipative structures in this resonator and reveal the predominance of a two-dimensional up-switching process over the formation of spatially periodic structures, leading to the truncation of the homogeneous hysteresis cycle.

Dynamical stability of entanglement between spin ensembles

description: We study the dynamical stability of the entanglement between the two spin ensembles in the presence of an environment. For a comparative study, we consider the two cases: a single spin ensemble, and two ensembles linearly coupled to a bath, respectively. In both circumstances, we assume the validity of the Markovian approximation for the bath. We examine the robustness of the state by means of the growth of the linear entropy which gives a measure of the purity of the system. We find out macroscopic entangled states of two spin ensembles can stably exist in a common bath. This result may be very useful to generate and detect macroscopic entanglement in a common noisy environment and even a stable macroscopic memory.

Development of a minimally invasive implantable optical sensor to monitor spinal cord oxygenation using near-infrared spectroscopy
Creators: name: Askari, Shahbaz
Publisher: name: University of British Columbia
Year: 2023

description: Neurological damage after traumatic spinal cord injury (SCI) occurs in two stages: an acute phase (<48 hours) and a subacute phase (48 hours to 14 days), often causing severe hemorrhage. The primary treatment involves raising mean arterial pressure (MAP) to enhance blood flow and boost oxygenation levels of spinal cord tissue. A crucial challenge in managing acute SCI is the need for techniques that non-invasively measure real-time blood flow and oxygenation. Continuous-wave near-infrared spectroscopy (CW-NIRS) offers benefits such as portability, cost-effectiveness, and safety due to its employment of non-ionizing, near-infrared radiation. However, it has limitations such as moderate spatial resolution, restricted penetration depth, and low signal-to-noise ratio. To counter these challenges, researchers have proposed the use of an implantable NIRS sensor. However, most of the research surrounding this approach has, so far, been mainly conducted in animal models. Hence, the primary objective of my research was to transition this approach from animal models and adapt it for clinical applications in SCI. In my research, I progressed from the SC-NIRS V4 sensor (Spinal Cord NIRS version 4 sensor), designed to validate a fabrication technique for more complex and precise encapsulation fabrication. Next, by developing SC-NIRS V5, I incorporated an implantable silicone elastomer for sensor encapsulation and an implantable connector to simplify the sensor’s implantation and removal process. I also developed the SC-NIRS V6 platform, specifically designed to accommodate a spatially resolved (SR) NIRS algorithm for improved accuracy. My research program was successfully concluded by implanting a SC-NIRS V5 sensor, which I designed and developed in a patient with acute traumatic spinal cord injury for the first time. The sensor effectively monitored and recorded spinal cord tissue oxygenation for 42 hours with a high degree of accuracy, providing valuable data that matched the patient's clinical condition. This is the first reported continuous monitoring of spinal cord oxygenation in a human participant using an implantable sensor.

description: MHD turbulence has long been proposed as a mechanism for the heating of coronal loops in the framework of the Parker scenario for coronal heating. So far most of the studies have focused on its dynamical properties without considering its thermodynamical and radiative features, because of the very demanding computational requirements. In this paper we extend this previous research to the compressible regime, including an energy equation, by using HYPERION, a new parallelized, viscoresistive, three-dimensional compressible MHD code. HYPERION employs a Fourier collocation -- finite difference spatial discretization, and uses a third-order Runge-Kutta temporal discretization. We show that the implementation of a thermal conduction parallel to the DC magnetic field induces a radiative emission concentrated at the boundaries, with properties similar to the chromosphere--transition region--corona system.
