description: Multiferroics, where two or more ferroic order parameters coexist, is one of the hottest fields in condensed matter physics and materials science[1-9]. However, the coexistence of magnetism and conventional ferroelectricity is physically unfavoured[10]. Recently several remedies have been proposed, e.g., improper ferroelectricity induced by specific magnetic[6] or charge orders[2]. Guiding by these theories, currently most research is focused on frustrated magnets, which usually have complicated magnetic structure and low magnetic ordering temperature, consequently far from the practical application. Simple collinear magnets, which can have high magnetic transition temperature, have never been considered seriously as the candidates for multiferroics. Here, we argue that actually simple interatomic magnetic exchange interaction already contains a driving force for ferroelectricity, thus providing a new microscopic mechanism for the coexistence and strong coupling between ferroelectricity and magnetism. We demonstrate this mechanism by showing that even the simplest antiferromagnetic (AFM) insulator MnO, can display a magnetically induced ferroelectricity under a biaxial strain.

description: Locating the boundaries of consecutive blocks of quantum information is a fundamental building block for advanced quantum computation and quantum communication systems. We develop a coding theoretic method for properly locating boundaries of quantum information without relying on external synchronization when block synchronization is lost. The method also protects qubits from decoherence in a manner similar to conventional quantum error-correcting codes, seamlessly achieving synchronization recovery and error correction. A family of quantum codes that are simultaneously synchronizable and error-correcting is given through this approach.

description: The transnational consumption of Hindi popular cinema (referred to commonly as "Bollywood") and its narrative film music figures prominently as an element of globalized cultural production through popular media. While scholars have noted the importance of Hindi films in defining local and global identities and aesthetics both in India and abroad, little attention has been given to the animations of Bollywood within transnational digital social networks, especially via popular music genres and highly accessible media, such as YouTube and music blogs. This paper analyzes how Bollywood is re-signified and attuned to popular and underground music in Tunisia and Algeria in its contextualization on the Internet. My research focuses on the relationship between Hindi film songs and Tunisian and Algerian styles of popular music (mizwid and raï, respectively), as well as the implications behind the digital "mashups" (or mixing) of these genres. The majority of mizwid and raï music videos on YouTube, for example, are visually represented not by the original performer, but by well-known scenes from Hindi films. These juxtapositions (referred to informally as Bollymizwid or Bollyraï) – as well as the re-arrangements, fragmentations, and redefinitions representative of Hindi film songs, of mizwid, and of raï – represent a critical juncture in the creation of cosmopolitan identities and counter-public spheres through the digital manipulation of a transnational musical and visual medium. Indeed, the transnational flow of popular music genres within digital public spheres redraws lines of selfhood and nationhood, complicating the ways in which individuals access and perform cosmopolitanism. Encompassing the transnational movements of digital media, this study examines the routes by which Bollyraï and Bollymizwid access and correspond to South Asian popular culture, as well as the dialogues of cosmopolitanism between Algerians and Tunisians both "at home" and in the Francophone diaspora.

description: No abstracts are to be cited without prior reference to the author.Alternative life-history tactics are common in fishes and many cases involve resident and migratory life styles. The resident tactic may involve both sexes or be restricted to males. Disruptive selection favouring alternative tactics may arise from two different evolutionary mechanisms. On the one hand, alternative migratory tactics may be the result of sexual selection for alternative reproductive phenotypes that impact other aspects of life-history, including resource exploitation. On the other hand, alternative migratory tactics may be caused by natural selection favouring divergence to exploit multiple niches which in turn impacts reproductive tactics

description: Background: Sensory tricks are compensatory gestures that cervical dystonia (CD) patients use to reduce abnormal neck posture and movements. Although sensory tricks are common in CD, little is known about whether trick efficacy changes over time or has effect on quality of life. Methods: We analyzed clinical data and video recordings from 188 patients with isolated CD. We calculated the duration of CD and assessed the Toronto Western Spasmodic Torticollis Rating Scales and the Cervical Dystonia Impact Profile (CDIP-58). Results: A longer duration of CD corresponded to a less effective sensory trick (r(187) = 0.1901, p = 0.009). Patients who demonstrated more effective sensory tricks reported higher sleep-related quality of life than patients with less effective sensory tricks (r(187) = 0.1680, p = 0.0212). There were no significant relationships between the effectiveness of a sensory trick and the other aspects of quality of life as measured by the CDIP-58. Discussion: Patients who have had CD longer had less effective sensory tricks consistent with patients’ verbal reports of previously having a trick that no longer works. Patients should be apprised of a wide variety of sensory tricks because their previous tricks may lose efficacy over time and because more effective tricks are associated with higher sleep-related quality of life.

description: We present continuum observations of the Perseus B1-E region from the Herschel Gould Belt Survey. These Herschel data reveal a loose grouping of substructures at 160 - 500 micron not seen in previous submillimetre observations. We measure temperature and column density from these data and select the nine densest and coolest substructures for follow-up spectral line observations with the Green Bank Telescope. We find that the B1-E clump has a mass of ~ 100 solar masses and appears to be gravitationally bound. Furthermore, of the nine substructures examined here, one substructure (B1-E2) appears to be itself bound. The substructures are typically less than a Jeans length from their nearest neighbour and thus, may interact on a timescale of ~ 1 Myr. We propose that B1-E may be forming a first generation of dense cores, which could provide important constraints on the initial conditions of prestellar core formation. Our results suggest that B1-E may be influenced by a strong, localized magnetic field, but further observations are still required.

description: No abstracts are to be cited without prior reference to the author.1 ) Occupancy – abundance relationships (OA) reflect the area used by a population as a function of its abundance. OA are generally non‐linear and logically show that with increasing abundance a population uses more space. The form of the OA will vary by species, however, because of behavioural and competitive mechanisms. Furthermore, the relationship can vary over time because of external forcing factors such changes in suitable habitat availability. 2 ) Commonly single species OA are estimated (also called intraspecific (ssOA)), one can also estimate OA over several species within a single time (also called interspecific or multispecies (msOA)) but here we deal with a expected value of the msOA  (eOA) which we define as the global relationship with all species and all years and a single fitted model. 3 ) We examined the eOA for 32 George’s Bank fish species from 1963‐2006, fitting linear models and a spline smoother and we examined the temporal trend in the eOA residuals. Residuals of early years in the time series showed a much greater probability to be positive while latter years negative. This suggests that in more recent times, populations tended to occupy less area for any given level of abundance than earlier and relative to the expected value. 4 ) The above pattern is consistent with the ecological interpretation of how populations respond to habitat destruction and stress which is postulated to have increased on George’s Bank from 1963‐2006. That is, populations tend to hyper‐aggregate in some patches of remaining habitat though are less likely to be found in suitable though disparate patches of habitat because they cannot find them, insufficient corridors exist to link patches, or behavioural mechanisms lead to concentration of the remaining individuals as a response to stress. 2 5 ) Theoretical work has suggested that contraction of populations in response to habitat destruction and stress can result in local extinction of certain species over the long run – thus termed an “extinction debt” owing to its latent response. Counter‐intuitively, those most likely to suffer local extinction are those which were often the most abundant and best competitors in the undisturbed system. The increase in destructive fishing effort on George’s Bank since the rise of industrial fisheries in the 1950s and occupancy declines of many species is a phenomenon consistent with extinction debt.

description: We investigate the properties of holographic fermions in charged Lifshitz black holes at finite temperature through the AdS/CFT correspondence. In the charged Lifshitz background with the dynamical exponent $z=2$, we find that the dispersion relation is linear. The scaling behavior of the imaginal part of the Green function relative to $k_{\perp}=k-k_F$ is also discussed. We find, although the system has linear dispersion relation and quadratic quasi-particle width, it does not satisfy Luttinger's theorem. We also find that the variation of the scaling parameters $α$ and $β$ is small as the charge $q$ varies. Furthermore, we also discuss the effect of the dynamical exponent $z$ by considering the cases $z=4$ and $z=6$ and show that $ImG_{ii}$ become smooth when the dynamical exponent $z$ increases.

Wrist--Wounds and injuries

description: Patients with poststroke complex regional pain syndrome (CRPS) show different symptoms compared to other types of CRPS, as they usually complain of shoulder and wrist pain with the elbow relatively spared. It is thus also known by the term “shoulder-hand syndrome.”

The aim of this study is to present a possible pathophysiology of poststroke CRPS through ultrasonographic observation of the affected wrist before and after steroid injection at the extensor digitorum communis (EDC) tendon in patients suspected with poststroke CRPS.

Prospective evaluation and observation, the STROBE guideline checklist was used.

Twenty-three patients diagnosed as poststroke CRPS in accordance to clinical criteria were enrolled. They had a Three Phase Bone Scan (TPBS) done and the cross-sectional area (CSA) of EDC tendon was measured by using ultrasonography. They were then injected with steroid at the EDC tendon. The CSA of EDC tendon, visual analogue scale (VAS), and degree of swelling of the wrist were followed up 1 week after the injection.

TPBS was interpreted as normal for 4 patients, suspected CRPS for 10 patients, and CRPS for 9 patients. Ultrasonographic findings of the affected wrist included swelling of the EDC tendon. After the injection of steroid to the wrist, CSA and swelling of the affected wrist compared to that before the treatment was significantly decreased (P < 0.001). The VAS score declined significantly after the injection (P < 0.001).

Our results suggest that the pathophysiology of poststroke CRPS might be the combination of frozen shoulder or rotator cuff tear of shoulder and soft tissue injury of the wrist caused by the hemiplegic nature of patients with stroke.

description: Weak gravitational lensing by galaxy clusters on faint higher redshift galaxies has been traditionally used to study the cluster mass distribution and as a tool to identify clusters as peaks in the shear maps. However, it becomes soon clear that peaks statistics can also be used as a way to constrain the underlying cosmological model due to its dependence on both the cosmic expansion rate and the growth rate of structures. This feature makes peak statistics particularly interesting from the point of view of discriminating between General Relativity and modified gravity. Here we consider a general class of $f(R)$ theories and compute the observable mass function based on the aperture mass statistics. We complement our theoretical analysis with a Fisher matrix forecast of the constraints that an Euclid\,-\,like survey can impose on the $f(R)$ model parameters. We show that peak statistics alone can in principle discriminate between General Relativity and $f(R)$ models and strongly constrain the $f(R)$ parameters that are sensitive to the non-linear growth of structure. However, further analysis is needed in order to include possible selection function in the peaks redshift determination.

description: No abstracts are to be cited without prior reference to the author.Experience has shown that the recovery of collapsed fish stocks takes place over long periods of time, and much longer than can be predicted by traditional fishery population models. It is here hypothesized that the collapse of a fish stock is associated with the disruption of biological mechanisms that sustain life cycle closure in space and time. Based on a review of case studies, we argue that stock collapses not only entail loss of biomass but key structural elements related to life cycle diversity (e.g., stock components, spawning units, contingents) as well as a social breakdown. Behavioral mechanisms are identified that are sufficient to explain how these structural elements can contribute to the recovery of depleted populations.

description: This study draws on a case study of Wukan and interviews with migrants and peasants in other sites to examine how migration shapes popular resistance in migrant-sending communities (i.e. rural China). Findings demonstrate multidimensional roles played by migrants and returned migrants who act as a vehicle of informational and ideological transmission and at times directly participate in or even lead rural resistance in origin communities. Both the transmission and participation processes foster political consciousness and action orientations among peasants. The importance of migrants is exemplified in the Wukan protests but is also found in other settings under study. In general, migrants represent a latent political force that acts upon serious grievances back home. The findings provide a useful lens for understanding the diffusion of popular resistance and the linkage between urban and rural activism in China.

description: We have studied Electroweak Symmetry Breaking (EWSB) fine-tuning in the context of two unified Supersymmetry scenarios: the Constrained Minimal Supersymmetric Model (CMSSM) and models with Non-Universal Higgs Masses (NUHM), in light of current and upcoming direct detection dark matter experiments. We consider both those models that satisfy a one-sided bound on the relic density of neutralinos, $Ω_χ h^2 < 0.12$, and also the subset that satisfy the two-sided bound in which the relic density is within the 2 sigma best fit of WMAP7 + BAO + H0 data. We find that current direct detection searches for dark matter probe the least fine-tuned regions of parameter-space, or equivalently those of lowest Higgs mass parameter $μ$, and will tend to probe progressively more and more fine-tuned models, though the trend is more pronounced in the CMSSM than in the NUHM. Additionally, we examine several subsets of model points, categorized by common mass hierarchies; $M_{χ_0} \sim M_{χ^\pm}, M_{χ_0} \sim M_{\stau}, M_{χ_0} \sim M_{\stop_1}$, the light and heavy Higgs poles, and any additional models classified as "other"; the relevance of these mass hierarchies is their connection to the preferred neutralino annihilation channel that determines the relic abundance. For each of these subsets of models we investigated the degree of fine-tuning and discoverability in current and next generation direct detection experiments.

Non-singlet sectors of the c=1 matrix model with connections to two dimensional string theory
Creators: name: Rabideau, Charles
Publisher: name: University of British Columbia
Year: 2012

description: The goal of this thesis is to study non-singlet sectors of the c=1 matrix model in order to determine their connection with string theory in two space-time dimensions. It is well understood that the singlet sector of this matrix model is related to the closed string sector of the string theory. The adjoint sector has been connected to long strings stretching from an FZZT brane at infinity. The goal is to find a sector which includes a large number of these long strings which condense to form an FZZT brane in line with a proposal due to Gaiotto. Sectors corresponding to symmetric and antisymmetric tensor products of the fundamental and antifundamental representation of the U(N) symmetry of the matrix model are studied. Partition functions of the matrix model with a harmonic oscillator potential as well as bases for the Hilbert spaces are found for all these sectors. The first two representations are studied using a collective field approach with the inverted oscillator potential applicable to the c=1 model and are found to contain large numbers of long strings which form a free bosonic gas in the large N limit and so do not condense. On the other hand, in the third sector the degrees of freedom are fermionic and a shift in the ground state energy is found in the harmonic oscillator potential, which points to the existence of a Fermi sea and the condensation of the long strings. A collective field that can be used to study this sector is proposed and the technical difficulties presented by the study of this sector are discussed, but its study is left for future work.

description: We define and study hole-like excitations (the Lieb II mode) in a weakly interacting Bose liquid subject to external confinement. These excitations are obtained by semiclassical quantization of gray solitons propagating on top of a Thomas-Fermi background. Radiation of phonons by an accelerated gray soliton leads to a finite life-time for the trapped Lieb II mode. It is shown that, for a large number of trapped atoms, most of the Lieb II levels can be experimentally resolved.

A Technique for Counting NATted Hosts

description: There have been many attempts to measure how many hosts are on the Internet. Many of those end-points, however, are NAT boxes (Network Address Translators), and actually represent several different computers. We describe a technique for detecting NATs and counting the number of active hosts behind them. The technique is based on the observation that on many operating systems, the IP header's ID field is a simple counter. By suitable processing of trace data, packets emanating from individual machines can be isolated, and the number of machines determined. Our implementation, tested on aggregated local trace data, demonstrates the feasibility (and limitations) of the scheme.

description: No abstracts are to be cited without prior reference to the author.Whiting and cod are two closely related gadoids, sharing the same grounds in the northern European waters as well as most of their life-cycle features. Many studies have investigated the level of mixing of adults in both species for more than one century, using a wide spectrum of methods such as tagging experiments, parasitic tags, otolith analysis, meristics and morphometrics. This large amount of data is particularly valuable to evaluate the migration patterns of adults and to detect homing behaviour, but do not allow to draw any conclusion about the natal origin of the fish and thus to discriminate natal homing from entrainment. Since the last decade, several studies have depicted the population genetic structure of cod and whiting in the NE Atlantic, providing useful informations about the extent of gene flow between populations through the passive drift of eggs and larvae or the active migration of adults. Population genetic structure and adult migration patterns displayed substantial discrepancies, and the purpose of this talk is to review all these discrepancies reported in the literature for cod and whiting. The comparison of gene flow and adult migration patterns in both species offers a very interesting opportunity to disentangle natal homing from entrainment.

Search for FCNC single top-quark production at sqrt(s) = 7 TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Results on the search for flavor-changing neutral-current single top-quark production are reported. Data collected with the ATLAS detector at a center-of-mass energy of sqrt(s) = 7 TeV and corresponding to an integrated luminosity of 2.05 fb^-1 are used. Candidate events with a leptonic top-quark decay signature are classified into signal- and background-like events using a neural network. No signal is observed in the output distribution and a Bayesian upper limit on the production cross-section is placed. The observed 95% C.L. upper limit on the cross-section multiplied by the t -> Wb branching fraction is measured to be sigma(qg -> t) x B(t -> Wb) < 3.9 pb. This upper limit can be converted into an upper limit of the coupling strength k_ugt/Lambda < 6.9 x 10^-3 TeV^-1 and k_cgt/Lambda < 1.6 x 10^-2 TeV^-1 and on the branching fractions B(t -> ug) < 5.7 x 10^-5 and B(t -> cg) < 2.7 x 10^-4.

description: An important desired ingredient of superconducting quantum circuits is a readout scheme whose complexity does not increase with the number of qubits involved in the measurement. Here, we present a readout scheme employing a single microwave line, which enables simultaneous readout of multiple qubits. Consequently, scaling up superconducting qubit circuits is no longer limited by the readout apparatus. Parallel readout of 6 flux qubits using a frequency division multiplexing technique is demonstrated, as well as simultaneous manipulation and time resolved measurement of 3 qubits. We discuss how this technique can be scaled up to read out hundreds of qubits on a chip.

description: Background: Rotator cuff tear (RCT) has been believed to be related to specific types of the acromion. However, most of the studies were performed on a small number of patients with surgical findings not considering the severity of RCT.
Purpose: To analyze the relationship between age, gender, the side of the shoulder, the acromion type, and the severity of RCT using shoulder magnetic resonance arthrography (MRA).
Material and Methods:  A total of 277 shoulder MRA findings were analyzed by a radiologist specializing in the musculoskeletal system. The relationship between variables (age, gender, side of the shoulder and acromion type) and the injury of the supraspinatus (no rupture, partial rupture, full rupture, complete rupture) was confirmed. The partial tear of the supraspinatus tendon was divided into bursal and articular side tear in order to investigate the damage caused by the anatomical difference of the acromion. We also confirmed the differences between single supraspinatus injury and multiple RCTs.
Results: The severity of supraspinatus tear and multiple RCTs were statistically significant with the old age, female and the right side of the shoulder, but not with a specific acromion type. In supraspinatus partial tear, there was no statistical difference between bursal and articular side tears.
Conclusion: Our study revealed that the age at which degeneration could occur also was associated with multiple RCTs and is considered to be the most important factor in RCT, not anatomical structures such as acromion type.

Epidemiology

description: Importance
There have been few large-scale studies that have included a risk factor analysis for CTS. No prior study has investigated and validated the relationship between the occurrence of CTS and known risk factors using nationwide health care database.
Objective
To confirm the actual risk factors for CTS out of various known risk factors
Design
We conducted this study using a retrospective cohort model based on the combined two databases of the Korean National Health Insurance System; the national periodic health screening program database from 2002–2003 and health insurance database of reimbursement claims from 2003 through 2013.
Setting
A population-based retrospective cohort study.
Participants
First, we randomly sampled 514,795 patients who represented 10% of the 5,147,950 people who took part in periodic health screenings in 2002–2003. Existing CTS patients were excluded from this group. Therefore, this study finally included 512,942 participants and followed up their medical records from 2003–2013.
Main Outcomes and Measures
Desired outcomes were the incidence rate of CTS in patients with various risk factors and the hazard ratios of risk factors affecting the disease’s occurrence.
Results
The incidence of CTS was highest in patients in the age of 40s, in the moderate obesity group, in females, and in patients with diabetes mellitus (DM). The hazard ratio analysis revealed that the following risk factors were strongly related to the occurrence of CTS: age of 40s, female, obesity, DM, rheumatoid arthritis, gout, and Raynaud’s syndrome. However, ESRD, hypothyroidism and smoking were not correlated with CTS occurrence.
Conclusions and Relevance
In our large-scale cohort study, risk factors such as being in one’s 40s, obesity, being female, suffering from DM, and rheumatoid arthritis were reaffirmed as those of CTS occurrence.

description: No abstracts are to be cited without prior reference to the author.We applied an interacting particle model to the Icelandic capelin stock to reproduce the spawning migration route for three different years, successfully predicting the route for 2008. Using available temperature data and approximated currents, and without using artificial forcing terms or a homing instinct, our model was able to reproduce the observed migration routes from all three years. By means of a sensitivity analysis we identified oceanic temperature and the balance between the influence of interaction among particles and the particles’ response to temperature as the control parameters most significant in determining the migration route. In order to maintain the same dynamics between different simulations, we argue a linear relationship between the time-step, radii of interactions, and the spatial resolution, and we argue that these scale as N −1/2 , where N is the number of particles. We also discuss a bioenergetic model for the spawning migration of the capelin.
Time domains of the cardio-respiratory response in bowfin (Amia calva) and implications for cardio-respiratory control in fish
Creators: name: Porteus, Cosima Sandra
Publisher: name: University of British Columbia

description: Time domains of the hypoxic ventilatory response (HVR) are time dependent changes in ventilation that take place without changes in metabolic rate or arterial PCO2. Time domains of the HVR have been described in mammals along with their underlying mechanisms. Each time domain reflects a different change in the various steps in the control of breathing. Peripheral chemoreceptors are necessary for the expression of all time domains in mammals and changes in their sensitivity (reflected in release of different neurotransmitters) are involved in several of the time domains. I demonstrated that neuroepithelial cells (NECs) in the gills of trout (Oncorhynchus mykiss) and goldfish (Carassius auratus) contain serotonin, but not acetylcholine or catecholamines. Acetylcholine was expressed in bipolar neurons in the filaments, and nerve bundles near the efferent filament arteries (eFA) in trout and goldfish and evidence suggests that they may play a key role in producing the HVR in these species. In bowfin (Amia calva), I found five different types of serotonin containing NECs in the gills (identified as Type I to V). Three of these cell types (I - III) had the potential to be oxygen chemoreceptors. Time domains were evident in the HVR of bowfin during moderate exposure to hypoxia but only when they did not have access to air. In these fish, all three putative chemoreceptors increased in size during sustained hypoxia. The NECs found in the basal lamina near the eFA responded exclusively to hypoxaemia (by changing cell size and shape) while the other two NEC types responded to aquatic hypoxia as well. Exposure to sustained hypoxia also caused changes within the oxygen transport cascade: the gill ventilatory sensitivity to hypoxia increased and the Hb-O₂ binding affinity decreased suggesting that acclimation to hypoxia in Amia elicits changes that both increase oxygen uptake and enhance oxygen delivery to the tissues. This thesis focused primarily on a time domain in bowfin similar to the ventilatory acclimatization to hypoxia seen in mammals and highlights the importance of changes in both the peripheral oxygen chemoreceptors as well as in the oxygen transport cascade in establishing this time dependent change.

Unhealthy Assimilation or Persistent Health Advantage? A Longitudinal Analysis of Immigrant Health in the United States

description: Existing evidence on immigrant health assimilation, which is largely based on cross-sectional data, suggests that immigrants' initial health advantage erodes over time. This study uses longitudinal data to directly compare the self-rated health trajectories of immigrants and the native-born population. Data come from four panels of the Survey of Income and Program Participation (1996, 2001, 2004, and 2008), with each panel containing 2-4 years of health information. Results show that immigrants’ self-rated health remained stable during the period under study, but there was a concomitant decline in health for the native-born population. This result pointed to a persistent health advantage of immigrants during the period under study. The pattern held for immigrants of different length of residence and was especially salient for those originally from Latin America and Asia. Our findings that immigrants maintain their health advantage do not support the pattern of unhealthy assimilation commonly reported in cross-sectional studies.
