description: In the present study, isoquinoline sulfonic acid thiocyanate (isoquinoline-SO3H)SCN and isoquinoline sulfonic acid chloride (isoquinoline-SO3H)Cl as a novel and heterogeneous catalyst were designed and synthesized by a simple and inexpensive procedure. The prepared heterogeneous catalyst was characterized by FT-IR, 1H NMR, and 13C NMR techniques. Then, the catalytic activity of (isoquinoline-SO3H)SCN and (isoquinoline-SO3H)Cl were successfully investigated for the synthesis of aryl and heteroaryl thiocyanates derivatives through a one-pot reaction. Moreover, the use of (isoquinoline-SO3H)SCN provides a quite simple and more convenient procedure, due to it has both acidic group and thiocyanation agent in reaction. The present procedure offers advantages such as the usage of a commercially available materials, cheap and chemically stabile reagents, short reaction time, excellent yield, ease of separation by simple filtration, and simple reaction work-up.

description: Exclusive photoproduction of vector mesons in the perturbative two-gluon exchange formalism depends significantly on nucleon and nuclear gluon distributions. In the present study we calculate total cross sections and rapidity distributions of $J/ψ(1s)$, $ψ(2s)$, $Υ(1s)$, $Υ(2s)$, and $Υ(3s)$ in ultraperipheral proton-lead (pPb) and lead-lead (PbPb) collisions at the CERN Large Hadron Collider (LHC) at $\sqrt{s_{_{NN}}}=5$ TeV and $\sqrt{s_{_{NN}}}=2.76$ TeV respectively. Effects of gluon shadowing are investigated and potentials for constraining nuclear gluon modifications are discussed.

This generalises the Bouchard-Marino conjecture and places Hurwitz-Hodge integrals, which arise in the Gromov--Witten theory of target curves with orbifold structure, in the context of the Eynard-Orantin topological recursion.

description: A common goal in the control of a large network is to minimize the number of driver nodes or control inputs. Yet, the physical determination of control signals and the properties of the resulting control trajectories remain widely under-explored. Here we show that: (i) numerical control fails in practice even for linear systems if the controllability Gramian is ill-conditioned, which occurs frequently even when existing controllability criteria are satisfied unambiguously; (ii) the control trajectories are generally nonlocal in the phase space, and their lengths are strongly anti-correlated with the numerical success rate and number of control inputs; (iii) numerical success rate increases abruptly from zero to nearly one as the number of control inputs is increased, a transformation we term numerical controllability transition. This reveals a trade-off between nonlocality of the control trajectory in the phase space and nonlocality of the control inputs in the network itself. The failure of numerical control cannot be overcome in general by merely increasing numerical precision---successful control requires instead increasing the number of control inputs beyond the numerical controllability transition.

title: Cognitive and affective deficits after chronic stress: role of inhibitory circuits
Creators: name: Wan-Yan-Chan, Derek L.
Publisher: name: Memorial University of Newfoundland

description: Major depressive disorder (MDD) is a debilitating neuropsychiatric disease that affects millions of people worldwide. With an increasing prevalence, it is imperative to find a cure for such disorder. Stress is a major risk factor of MDD and thus understanding the pathophysiological mechanism underlying the onset of stress-dependent depression could translate into possible future therapies. In the present study, we investigated if different stress exposure duration, short-term (ST-UCMS) and long-term stress (LT-UCMS), would result in distinct phenotypic profile in a mouse model of depression. We found that LT-UCMS resulted in increased more anhedonia-like symptoms than ST-UCMS and surprisingly, LT-UCMS exposure enhanced cognitive abilities. Both stress duration increased the expression of small-conductance calcium-dependent potassium channel subtype 3 (SK3C) mRNA within somatostatin (SST)- and parvalbumin (PV)-positive neurons. Furthermore, LT-UCMS regimen resulted in significantly higher SK3C-SST and SK3C-PV co-expression levels in the medial prefrontal cortex and nucleus accumbens, respectively. A sex- and region-specific increase in SST mRNA was reported after LT-UCMS exposure only. Notably, after LT-UCMS exposure, stressed females show a significant increase in SK3C-PV co-expression level in the NAcc, which was not observed in males. Similarly, females expressed higher level of SST mRNA in the mPFC after LT-UCMS exposure compared to males, and regarding PV mRNA, only males showed a significant decrease in NAcc, whereas for the CA1 region, only females had a decrease. Our results demonstrate that the length of stress exposure is a determinant factor in the onset of MDD and its effects could be mediated through differential transcriptomic profiles.

description: To identify the contributions of the multiband nature and the anisotropy of a microscopic electronic structure to a macroscopic vortex lattice morphology, we develop a method based on the Eilenberger theory near Hc2 combined with the first-principles band calculation to estimate the stable vortex lattice configuration. For a typical two-band superconductor MgB2, successive transitions of vortex lattice orientation that have been observed recently by small angle neutron scattering [Das, et al.: Phys. Rev. Lett. 108 (2012) 167001] are explained by the characteristic field-dependence of twoband superconductivity and the competition of sixfold anisotropy between the sigma- and pi-bands. The reentrant transition at low temperature reflects the Fermi velocity anisotropy of the sigma-band.

description: A spectroscopically detected Lyman alpha emitting halo at redshift 3.216 in the GOODS-N field is found to reside at the convergence of several Lyman alpha filaments. HST images show that some of the filaments are inhabited by galaxies. Several of the galaxies in the field have pronounced head-tail structures, which are partly aligned with each other. The blue colors of most tails suggest the presence of young stars, with the emission from at least one of the galaxies apparently dominated by high equivalent width Lyman alpha. Faint, more diffuse, and similarly elongated, apparently stellar features, can be seen over an area with a linear extent of at least 90 kpc. The region within several arcseconds of the brightest galaxy exhibits spatially extended emission by HeII, NV and various lower ionization metal lines. The gas-dynamical features present are strongly reminiscent of ram-pressure stripped galaxies, including evidence for recent star formation in the stripped contrails. Spatial gradients in the appearance of several galaxies may represent a stream of galaxies passing from a colder to a hotter intergalactic medium. The stripping of gas from the in-falling galaxies, in conjunction with the occurrence of star formation and stellar feedback in the galactic contrails suggests a mechanism for the metal enrichment of the high redshift intergalactic medium that does not depend on long-range galactic winds, at the same time opening a path for the escape of ionizing radiation from galaxies.

description: We report the first high spatial resolution near-infrared imaging of the Vela pulsar in the $K_s$ band obtained with the new adaptive optics system recently mounted on the Gemini-South telescope. For the first time, we have firmly detected the pulsar in this band with $K_s$ $\approx$ 21\fm8, and have resolved in detail an extended feature barely detected previously in the immediate vicinity of the pulsar in the $J_sH$ bands. The pulsar $K_s$ flux is fully consistent with the extension of the flat optical spectrum of the pulsar towards the infrared and does not confirm the strong infrared flux excess in the pulsar emission suggested earlier by the low spatial resolution data. The extended feature is about two times brighter than the pulsar and is likely associated with its X-ray counter-jet. It extends $\sim$ 2\asec southwards of the pulsar along the X-ray ounter-jet and shows knot-like structures and a red spectrum.

Glueball Spectrum in a Gauge Theory with Two Dynamical Scales

description: We investigate the glueball spectrum of a strongly coupled gauge theory with two dynamical scales. The main tool is the use of the gauge/gravity duality. The model we study has a known graviational dual, which arises from a type IIB D-brane configuration. It exhibits two dynamical scales, separated by a nearly conformal region. Thus, it is of great interest for the study of walking in gauge theories. By using the gravitational description, we are able to compute analytically the glueball mass spectrum in a certain range of the parameter space of the theory. Within that range, we do not find a light state that could be associated with a slight breaking of conformal invariance. Finally, we show that in this model there can be an order of magnitude hierarchy between the scale of confinement, given by the lowest glueball mass, and the scale of chiral symmetry breaking, determined by the lowest vector-meson mass.

The new device design incorporates silica side walls close to the microresonators which not only enable placing the coupling fibers on the same plane with respect to the microtoroid resonator but also provides mechanical stability, leading to an add-drop filter with high drop efficiency and improved robustness to environmental perturbations. We show that this new device can be thermally tuned to drop desired wavelengths from the bus without significantly affecting the drop efficiency, which is around 57%

Open String Self-energy on the Lightcone Worldsheet Lattice

description: We continue our study of open string perturbation theory on the lightcone worldsheet lattice, which is an $M\times N$ rectangular grid. Here $M$ is the number of $P^+$ units and $N$ is the number of $ix^+$ units. We extend our previous analysis to the bosonic open string one planar loop self-energy. We find that, when all open string coordinates satisfy Neumann conditions, the ultraviolet worldsheet divergences associated with the closed string tachyon and boundary effects can be cancelled by renormalization of bulk ($AM^1$) and boundary ($BM^0$) worldsheet "cosmological constants". The bulk divergence for the open string matches that for the closed string. The open string tachyon mass shift displays the dilaton logarithmic divergence with the correct coefficient for its consistent absorption by renormalization of the string tension. The ultraviolet contribution to the open string gluon mass shift vanishes, in accord with its interpretation as a gauge particle. We also find that when the bosonic string ends on a D-brane additional negative powers of $\ln M$ multiply the bulk and boundary divergences. These can no longer be cancelled by the "cosmological constants", perhaps pointing to the need, in the presence of D-branes, for the cancellations of divergences provided by supersymmetry.

description: With this presentation, I am describing my experience as an astrophysicist who decided to do her next postdoc in a different research field. Driven by a growing passion for sustainability and an eagerness to put my skills to work towards protecting the environment, I applied for various industry jobs in that sector as well as one postdoc position at the Technical University of Denmark in the group of Energy System Operation and Management. I was fortunate to obtain the postdoc position in Denmark and it turned out to be an extremely rewarding 1.5 years experience. In this presentation, I talk about the shift from astronomy to electrical engineering, and in particular what made it an easier transition. I also answer the two questions I've been asked the most: 1) What made me seek a job outside of astronomy? and 2) What drove me back to astronomy?

The contributions from the one loop diagrams and the Weinberg operators are taken into account. Adopting some assumptions on the relevant parameter space, we give the numerical results analysis. The numerical results for neutron EDM can reach $1.05\times 10^{-25}(e.cm)$, which is about the experimental upper limit.

Transfer

description: The success of Germany’s dual education and training system is viewed worldwide as an example to follow. But how can other countries effectively transfer the model to their national contexts?

Prof. Dr. Dieter Euler expores this question in a new study in which he identifies 11 components of the dual system and examines the extent to which each is transferable in various stages of implementation.  Emphasizing operational considerations in implementation, his approach shows how individual elements can be transferred and adapted to the uniques conditions of a country.

The study will be available in German, English, French and Spanish.

description: We perform a global fit study on the new agegraphic dark energy (NADE) model in a non-flat universe by using the MCMC method with the full CMB power spectra data from the WMAP 7-yr observations, the SNIa data from Union2.1 sample, BAO data from SDSS DR7 and WiggleZ Dark Energy Survey, and the latest measurements of $H_0$ from HST. We find that the value of $Ω_{k0}$ is greater than 0 at least at the 3$σ$ confidence levels (CLs), which implies that the NADE model distinctly favors an open universe. Besides, our results show that the value of the key parameter of NADE model, $n=2.673^{+0.053+0.127+0.199}_{-0.077-0.151-0.222}$, at the 1--3$σ$ CLs, where its best-fit value is significantly smaller than those obtained in previous works. We find that the reason leading to such a change comes from the different SNIa samples used. Our further test indicates that there is a distinct tension between the Union2 sample of SNIa and other observations, and the tension will be relieved once the Union2 sample is replaced by the Union2.1 sample. So, the new constraint result of the NADE model obtained in this work is more reasonable than before.

Investigating visual expertise in sculpture: A methodological approach using eye tracking

description: Research on visual expertise has progressed significantly due to the availability of eye tracking tools. However, attempts to bring together research on expertise and eye tracking methodology provoke several challenges, because visual information processes should be studied in authentic and domain-specific environments. Among the barriers to designing appropriate research are the proper definition of levels of expertise, the tension between internal (experimental control) and external (authentic environments) validity, and the appropriate methodology to study eye movements in a three-dimensional environment. This exploratory study aims to address these challenges and to provide an adequate research setting by investigating visual expertise in sculpting. Eye movements and gaze patterns of 20 participants were investigated while looking at two sculptures in a museum. The participants were assigned to four different groups based on their level of expertise (laypersons, novices, semi-experts, experts). Using mobile eye tracking, the following parameters were measured: number of fixations, duration of fixation, dwell time in relevant areas, and revisits in relevant areas. Moreover, scan paths were analysed using the eyenalysis approach. Conclusions are drawn on both the nature of visual expertise in sculpting and the potential (and limitations) of empirical designs that aim to investigate expertise in authentic environments.

description: A M-ary phase shift keying (PSK) quantum receiver consisting of displacement operations, photon counting, and electrical feed-back adaptive measurements is analyzed with a realistic model considering the effects of the sub-unity quantum efficiency and the dark counts of single-photon detectors, as well as the transmittance and the mode mismatch of beam splitters. Among these factors, the mode mismatch has the greatest impact on the error probability of the receiver with on-off detectors. The errors due to mode mismatch can be suppressed effectively by using photon-number-resolving detectors (PNRD) instead of on-off detectors.

description: Starting in 2013 February, Swift has been performing short daily monitoring observations of the G2 gas cloud near Sgr A* with the X-Ray Telescope to determine whether the cloud interaction leads to an increase in the flux from the Galactic center. On 2013 April 24 Swift detected an order of magnitude rise in the X-ray flux from the region near Sgr A*. Initially thought to be a flare from Sgr A*, detection of a short hard X-ray burst from the same region by the Burst Alert Telescope suggested that the flare was from an unresolved new Soft Gamma Repeater, SGR J1745-29. Here we present the discovery of SGR J1745-29 by Swift, including analysis of data before, during, and after the burst. We find that the spectrum in the 0.3-10 keV range is well fit by an absorbed blackbody model with kTBB ~ 1 keV and absorption consistent with previously measured values from the quiescent emission from Sgr A*, strongly suggesting that this source is at a similar distance. Only one SGR burst has been detected so far from the new source, and the persistent light curve shows little evidence of decay in approximately 2 weeks of monitoring after outburst. We discuss this light curve trend and compare it with those of other well covered SGR outbursts. We suggest that SGR J1745-29 belongs to an emerging subclass of magnetars characterized by low burst rates and prolonged steady X-ray emission 1-2 weeks after outburst onset.

description: The recently observed lepton mixing angle $θ_{13}$ of the MNS mixing matrix is well incorporated in a universal mixing hypothesis between quark and lepton sectors. This hypothesis asserts that, in the charged lepton diagonal base, all other mass matrices for up- and down-type quarks and light neutrinos are diagonalized by the same unitary matrix except for the phase elements. It is expressed as $V_{CKM}= U_{MNS}(δ^\prime)^\dagger P U_{MNS}(δ)$ for quark mixing matrix $V_{CKM}$ and lepton mixing matrix $U_{MNS}(δ)$ in the phenomenological level. Here $P$ is a diagonal phase mass matrix. $δ^\prime$ is a slightly different phase parameter from the Dirac CP violating phase $δ=1.1π$ (best fit) in the MNS lepton mixing matrix.

description: The concentration of melatonin is elevated during the night when patients mainly wear removable orthodontic appliances. Next to periodontal ligament fibroblasts and osteoblasts, macrophages react to mechanical strain with an increased expression of inflammatory mediators. Here, we investigated the impact of melatonin on RAW264.7 macrophages exposed to tensile or compressive strain occurring during orthodontic tooth movement in the periodontal ligament. Before exposure to mechanical strain for 4 h, macrophages were pre-incubated with different melatonin concentrations for 24 h, to determine the dependence of melatonin concentration. Afterwards, we performed experiments with and without mechanical strain, the most effective melatonin concentration (25 µM), and the melatonin receptor 2 (MT2) specific antagonist 4P-PDOT. The expression of inflammatory genes and proteins was investigated by RT-qPCR, ELISAs, and immunoblot. Both tensile and compressive strain increased the expression of the investigated inflammatory factors interleukin-1-beta, interleukin-6, tumor necrosis factor alpha, and prostaglandin endoperoxide synthase-2. This effect was inhibited by the addition of melatonin. Incubation with 4P-PDOT blocked this anti-inflammatory effect of melatonin. Melatonin had an anti-inflammatory effect on macrophages exposed to mechanical strain, independent of the type of mechanical strain. As inhibition was possible with 4P-PDOT, the MT2 receptor might be involved in the regulation of the observed effects.

description: We study the quantum phases of fermions with an explicit SU(N)-symmetric, Heisenberg-like nearest-neighbor flavor exchange interaction on the honeycomb lattice at half-filling. Employing projective (zero temperature) quantum Monte Carlo simulations for even values of N, we explore the evolution from a weak-coupling semimetal into the strong-coupling, insulating regime. Furthermore, we compare our numerical results to a saddle-point approximation in the large-N limit. From the large-N regime down to the SU(6) case, the insulating state is found to be a columnar valence bond crystal, with a direct transition to the semimetal at weak, finite coupling, in agreement with the mean-field result in the large-N limit. At SU(4) however, the insulator exhibits a subtly different valence bond crystal structure, stabilized by resonating valence bond plaquettes. In the SU(2) limit, our results support a direct transition between the semimetal and an antiferromagnetic insulator.

For T = 88 mK, C(H, theta=90) increases proportionally to H^{1/2} up to nearly the upper critical field Hc2, indicating the presence of line nodes. By contrast, C(H, theta=0) deviates upward from the H^{1/2} dependence for (H/Hc2)^{1/2} > 0.5. This behavior can be related to the suppression of Hc2 along the c direction, whose origin has not been resolved yet. Our data show that the unusual Hc2 limit becomes marked only when theta is smaller than 30. In order to explore the possible vertical line nodes in the gap structure, we measured the phi dependence of C in wide T and H ranges. However, we did not observe any in-plane angular oscillation of C within the accuracy of dC/C~0.5%. This result implies that field-induced excitations of the heavy quasiparticles occur isotropically with respect to phi, which is apparently contrary to the recent finding of a twofold thermal-conductivity oscillation.

description: We use the axially-deformed Skyrme Quasiparticle Random-Phase Approximation (QRPA) together with the SkM* energy-density functional, both as originally presented and with the time-odd part adjusted to reproduce the Gamow-Teller resonance energy in 208Pb, to calculate the matrix elements governing the neutrinoless double-beta decay of 76Ge, 130Te, 136Xe, and 150Nd. Our matrix elements in 130Te and 136Xe are significantly smaller than those of previous QRPA calculations, primarily because of the difference in pairing or deformation between the initial and final nuclei. In 76Ge and 150Nd our results are similar to those of less computationally intensive QRPA calculations. We suspect the 76Ge result, however, because we are forced to use a spherical ground-state, even though the HFB indicates a deformed minimum.

title: A call for community governance: wind energy implementation in Alberta through strategic environmental policymaking
Creators: name: Hudson, Emma
Publisher: name: Memorial University of Newfoundland

description: The transition towards green energy systems is a highly debated topic. While Canada promises sustainable changes to ensure climate change targets are reached, such efforts are not transpiring on the provincial level. This paper analyzes the difficulties of Alberta’s acceptance of wind energy, a strong contender for a green energy alternative, and possible solutions through community governance and strategic environmental policymaking. I provide two research questions that ask for an explanation of the resistance to wind energy in Alberta and what the opportunities are for community governance. To answer these questions, I present governance and ideology as obstacles to successful wind energy implementation. These factors possess fundamental and deeply-rooted origins. While policy efforts have been made to reduce carbon emissions, the general lack of acceptance of wind energy has created a province in stagnation - unable and unwilling to change amidst the federal and global appeals. By analyzing secondary literature, a governance typology, and a comparative policy analysis, this paper illustrates the benefits of a community governance, and community renewable energy (RE) by extension, for renewable energy implementation in contentious regions. Community governance presents a potential answer through policymaking methods that focus on citizens’ participation and collaboration. The results of this paper argue that the governance and ideology challenges constraining renewable energy in Alberta can partly be addressed through community governance and strategic environmental policymaking. From this, this paper urges the necessity of approaching climate change mitigation through adaptive approaches.

description: We address the issue of the validity of linear response theory for a closed quantum system subject to a periodic external driving. Linear response theory (LRT) predicts energy absorption at frequencies of the external driving where the imaginary part of the appropriate response function is different from zero. Here we show that, for a fairly general non-linear many-body system on a lattice subject to an extensive perturbation, this approximation should be expected to be valid only up to a time $t^*$ depending on the strength of the driving, beyond which the true coherent Schrödinger evolution departs from the linear response prediction and the system stops absorbing energy form the driving. We exemplify this phenomenon in detail with the example of a quantum Ising chain subject to a time-periodic modulation of the transverse field, by comparing an exact Floquet analysis with the standard results of LRT. In this context, we also show that if the perturbation is just local, the system is expected in the thermodynamic limit to keep absorbing energy, and LRT works at all times. We finally argue more generally the validity of the scenario presented for closed quantum many-body lattice systems with a bound on the energy-per-site spectrum, discussing the experimental relevance of our findings in the context of cold atoms in optical lattices and ultra-fast spectroscopy experiments.

description: We present near and mid--IR observations of a sample of Seyfert II galaxies drawn from the $12μ$m Galaxy Sample. The sample was observed in the J, H, K, L, M and N bands. Galaxy Surface Brightness Profiles are modeled using nuclear, bulge, bar (when necessary) and disk components. To check the reliability of our findings the procedure was tested using {\em Spitzer\/} observations of M\,31. Nuclear Spectral Energy Distributions (SEDs) are determined for 34 objects, and optical spectra are presented for 38, including analysis of their stellar populations using the STARLIGHT spectral synthesis code. Emission line diagnostic-diagrams are used to discriminate between genuine AGN and HII nuclei. Combining our observations with those found in the literature, we have a total of 40 SEDs. It is found that about 40\%\ of the SEDs are characterized by an upturn in the near-IR, which we have quantified as a NIR slope $α< 1$ for an SED characterized as $λf_λ \propto λ^α$. Three objects with an HII nucleus and two Seyfert nuclei with strong contamination from a circumnuclear starburst, also show an upturn. For genuine AGN this component could be explained as emission from the accretion disk, a jet, or from a very hot dust component leaking from the central region through a clumpy obscuring structure. The presence of a very compact nuclear starburst as the origin for this NIR excess emission is not favored by our spectroscopic data for these objects.

A Parameter Study for Baroclinic Vortex Amplification

description: Recent studies have shown that baroclinic vortex amplification is strongly dependent on certain factors, namely, the global entropy gradient, the efficiency of thermal diffusion and/or relaxation as well as numerical resolution. We conduct a comprehensive study of a broad range and combination of various entropy gradients, thermal diffusion and thermal relaxation time-scales via local shearing sheet simulations covering the parameter space relevant for protoplanetary disks. We measure the Reynolds stresses as a function of our control parameters and see that there is angular momentum transport even for entropy gradients as low as $β=-{d\ln s}/{d\ln r}={1}/{2}$, which corresponds to values observed in protoplanetary accretion disks. The amplification-rate of the perturbations, $Γ$, appears to be proportional to $β^2$ and thus proportional to the square of the \BV ($Γ\propto β^2 \propto N^2$). The saturation level of Reynolds stresses on the other hand seems to be proportional to $β^{1/2}$. This highlights the importance of baroclinic effects even for the low entropy gradients expected in protoplanetary disks.

description: Having moved predominantly online with the UK national lockdown of 2020, a comparison was made of two entrepreneurship courses at The University of Manchester, taught its first online academic year, with the previous year’s versions which were face to face. It was found that students generally adapted well to online teaching, feedback and attainment were similar to previous years. However, students felt it was important to have additional access to their lecturers through live sessions, extra assignment help, and need longer time to absorb the material with recorded lectures broken down into smaller videos and activities to aid concentration. They found the live session helpful to meet and work with peers and as part of their studies they want access to both asynchronous and synchronous learning methods. Analysis and recommendations were provided on what the authors consider to be the contributing pedagogic factors of delivering a successful online pedagogic approach in entrepreneurship and make recommendations as to how online learning could be improved.

description: We measured resistivity and specific heat of high-quality CsFe$_2$As$_2$ single crystals, which were grown by using a self-flux method. The CsFe$_2$As$_2$ crystal shows sharp superconducting transition at 1.8 K with the transition width of 0.1 K. The sharp superconducting transition and pronounced jump in specific heat indicate high quality of the crystals. Analysis on the superconducting-state specific heat supports unconventional pairing symmetry in CsFe$_2$As$_2$.

description: We study the P-odd effects related to the vorticity of the medium formed in noncentral heavy ion collisions. Using the kinetic Quark-Gluon Strings Model we perform the numerical simulations of the vorticity and hydrodynamical helicity for the various atomic numbers, energies and centralities. We observed the vortical structures typically occupying the relatively small fraction of the fireball volume. In the course of numerical simulations the noticeable hydrodanamical helicity was observed manifesting the specific mirror behaviour with respect to the reaction plane. The effect is maximal at the NICA and FAIR energy range.

Measurement of the elastoresistivity coefficients of the underdoped iron-arsenide Ba(Fe$_{0.975}$Co$_{0.025}$)$_2$As$_2$

description: A new method is presented for measuring terms in the elastoresistivity tensor $m_{ij}$ of single crystal samples with tetragonal symmetry. The technique is applied to a representative underdoped Fe-arsenide, Ba(Fe$_{0.975}$Co$_{0.025}$)$_2$As$_2$, revealing an anomalously large and anisotropic elastoresistance in comparison to simple metals. The $m_{66}$ coefficient follows a Curie-Weiss temperature dependence, providing direct evidence that the tetragonal-to-orthorhombic structural phase transition that occurs at $T_s$ = 97.5 K in this material is not the result of a true-proper ferro-elastic transition. Rather, the material suffers a pseudo-proper transition for which the lattice strain is not the primary order parameter.
