description: Vector magnetometry provides more information than scalar measurements for magnetic surveys utilized in space, defense, medical, geological and industrial applications. These areas would benefit from a mobile vector magnetometer that can operate in extreme conditions. Here we present a scanning fiber-coupled nitrogen vacancy (NV) center vector magnetometer. Feedback control of the microwave excitation frequency is employed to improve dynamic range and maintain sensitivity during movement of the sensor head. Tracking of the excitation frequency shifts for all four orientations of the NV center allow us to image the vector magnetic field of a damaged steel plate. We calculate the magnetic tensor gradiometry images in real time, and they allow us to detect smaller damage than is possible with vector or scalar imaging.

description: We present the result of radio and optical observations of the S0 galaxy IC 4200. We find that the galaxy hosts 8.5 billion solar masses of HI rotating on a ~90 deg warped disk extended out to 60 kpc from the centre of the galaxy. Optical spectroscopy reveals a simple-stellar-population-equivalent age of 1.5 Gyr in the centre of the galaxy and V- and R-band images show stellar shells. Ionised gas is observed within the stellar body and is kinematically decoupled from the stars and characterised by LINER-like line ratios.We interpret these observational results as evidence for a major merger origin of IC 4200, and date the merger back to 1-3 Gyr ago.

description: Objective: To compare the effects of intensity-matched acute exercise at different intensities on proinflammatory and anti-inflammatory cytokines between able-bodied (AB) and spinal cord injured (SCI) individuals. Design: Non-Randomized Controlled Trial. Setting: Community settings in São Paulo – Brazil. Participants: Eight AB and nine SCI paraplegic. Interventions: Participants underwent three exercise sessions at different relative intensities: at ventilatory threshold 1 intensity (VT1), 15% below VT1, and 15% above VT1. Similar energy expenditures were established from exercises with different intensities for each volunteer. The AB group was tested on a conventional treadmill, whereas the SCI group was tested on a treadmill adapted for wheelchair use. Blood samples were collected at baseline, immediately after, and 30 min after the exercise sessions. Outcome measures: Interleukin 1 receptor antagonist, interleukin 1 beta, interleukin 2, interleukin 4, interleukin 6, interleukin 10 and tumoral necrosis factor alpha were measured. Results: When groups were compared, interleukin – 2 was found higher, whereas interleukin – 4 and interleukin – 10 were found lower in the SCI group at all collection times in the three exercise intensities (all P P P = 0.01). Conclusion: Individuals with SCI may have to perform physical exercise at a higher volume or energy expenditure than AB individuals to obtain similar anti-inflammatory benefits of acute exercise.

description: Physical visualizations (i.e., data representations by means of physical objects) have been used for many centuries in medical and anatomical education. Recently, 3D printing techniques started also to emerge. Still, other medical physicalizations that rely on affordable and easy-to-find materials are limited, while smart strategies that take advantage of the optical properties of our physical world have not been thoroughly investigated. We propose the Anatomical Edutainer, a workflow to guide the easy, accessible, and affordable generation of physicalizations for tangible, interactive anatomical edutainment. The Anatomical Edutainer supports 2D printable and 3D foldable physicalizations that change their visual properties (i.e., hues of the visible spectrum) under colored lenses or colored lights, to reveal distinct anatomical structures through user interaction.

description: The study aimed at assessing whether differences exist in identity complexity and integration between 31 lesbian, gay, and bisexual (LGB) and 33 heterosexual youths whose mean age was 21.47 (SD = 3.27). It constitutes a pilot study using a newly created questionnaire, called Identity Labels and Life Contexts Questionnaire (ILLCQ), which assesses the interplay between identity dimensions and life contexts. The ILLCQ allows to assess identity integration on three levels: 1) the integration among the different domains of identity in their intersection with the various life contexts (assessed through salience and centrality); 2) the integration between an individual’s self-definition and the definition mirrored by others (perceived self-recognition); and 3) the integration between how she/he feels her/himself to be and the way she/he shows her/himself to others. Results suggest that identity salience is significantly variable across the life contexts for both LGB and heterosexual youths. The only significant difference found between groups was higher salience and centrality of the sexual orientation domain for LGB youths. This constitutes a sort of core identity for LGB participants, which seems to be missing in the heterosexual counterparts. LGB youths reported general lower identity recognition on the part of other people. Implications for clinical practice are discussed.

description: Parvovirus B19 is single-stranded DNA virus and can cause general flu-like symptoms or asymptomatic infection with rash and, more commonly in adults, arthritis, especially in the fingers and hands but also in the wrists and ankles. The present study aimed to investigate the involvement of parvovirus B19 in the development of rheumatoid arthritis and ankylosing spondylitis by demonstrating the presence of specific antiviral antibodies in patient’s serum samples. Serological methods (indirect ELISA test and Immunoblot test) to demonstrate the specific parvovirus B19 IgM/IgG antibodies were used. A total 36 serum samples, collected in 2015 from patients with rheumatoid arthritis (n=24) and ankylosing spondylitis (n=12) were tested. The average age of patients studied was 50 ± 13.2 years. Positive results for B19-IgM antibodies which are marker for acute B19 infection in 2/36 (5.55%) serum samples were detected. These two sera were from patients with diagnosis rheumatoid arthritis. Protective B19-IgG antibodies evidence of past infection in 17/36 (47.22%) patients were found. Thirteen of them were diagnosed with rheumatoid arthritis and four with ankylosing spondylitis. Two of the tested serum samples from patients with rheumatoid arthritis were positive for both investigated B19 markers. Rheumatoid diseases are one of the oldest problems of mankind, which is widespread today. This study is the basis for future more detailed tests aimed enrichment of diagnostic range on these diseases and inclusion of parvovirus B19 assays.

description: Coronal holes (CHs) are darker than quiet Sun (QS) when observed in coronal channels. This study aims to understand the similarities and differences between CHs and QS in the transition region using the \ion{Si}{4}~1394~Å line recorded by the Interface Region Imaging Spectrograph (IRIS) by considering the distribution of magnetic field measured by the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO). We find that \ion{Si}{4} intensities obtained in CHs are lower than those obtained in QS for regions with identical magnetic flux densities. Moreover, the difference in intensities between CHs and QS increases with increasing magnetic flux. For the regions with equal magnetic flux density, QS line profiles are more redshifted than those measured in CHs. Moreover, the blue shifts measured in CHs show an increase with increasing magnetic flux density unlike in the QS. The non-thermal velocities in QS, as well as in CHs, show an increase with increasing magnetic flux. However, no significant difference was observed in QS and CHs, albeit a small deviation at small flux densities. Using these results, we propose a unified model for the heating of the corona in the QS and in CHs and the formation of the solar wind.

description: Objectification theory posits that women internalize males’ sexualizing gaze upon them and pay more attention to their appearance than to their feelings. To date, the literature has focused on the differences that males and females arouse in objectification experiences of women. In the current study, a tripartite comparison of the effects of self-gaze, female gaze, and male gaze upon women’s self-objectification, body dissatisfaction, body shame, appearance anxiety, and negative mood was made with Turkish college women. The study utilized a 3x2 repeated measures factorial design with six different imagined scenarios comprised of three types of gaze (self, female, and male) and two types of clothing (swimsuit, and sweater and jeans). All dependent variables were significantly affected by clothing type. Body shame, negative mood, appearance anxiety, and state SO were significantly affected by the type of gaze. Interaction effects were significant for body dissatisfaction and negative mood.

description: Bulgaria is a country with the intermediate endemicity for hepatitis B virus (HBV) with predominance in adults between 40 and 49 years. Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are musculoskeletal conditions that cause severe long term pain and disability which prevalence increased with ageing. Reactivation of HBV is not rare event in patients receiving immunosuppressive therapy, but the prevalence of HBV markers among such patients is still unclear. The aim of the present work is to study distribution of two main HBV markers – HBV surface antigen (HbsAg), as marker for the present infection, and antibodies against HBV core antigen (anti-HBc), as a marker for past infection, among patients with AS and RA. The screening for HBV markers was done by commercial enzyme-linked assays for detection of HBsAg and anti-HBc in blood samples, for 14 sera samples concentration of HBV DNA were measured by quantitative real-time PCR. The study included 23 patients with AS and 24 – with RA. Two (8%) of the patients with AS were positive for HBsAg and 9 (39%) - were anti-HBc positive. From patients with RA 2 (8%) were HBsAg positive and 7 (29%) – were anti-HBc positive. The presence of low HBV DNA concentration (between 182 copies/ml and <116 copies/ml) were established in 2 patients with AS. In conclusion the prevalence of markers for past HBV infection was high among patients with AS and RA, which is reason for more strict screening of patients before immunosuppressive therapy.

description: Analytic continuation from Minkowski space to $(2,2)$ split signature spacetime has proven to be a powerful tool for the study of scattering amplitudes. Here we show that, under this continuation, null infinity becomes the product of a null interval with a celestial torus (replacing the celestial sphere) and has only one connected component. Spacelike and timelike infinity are time-periodic quotients of AdS$_3$. These three components of infinity combine to an $S^3$ represented as a toric fibration over the interval. Privileged scattering states of scalars organize into $SL(2,\mathbb{R})_L \times SL(2,\mathbb{R})_R$ conformal primary wave functions and their descendants with real integral or half-integral conformal weights, giving the normally continuous scattering problem a discrete character.

Involvement of muscarinic acetylcholine receptors in conditional discrimination task in eyeblink conditioning in mice
Creators: name: Ashrafur Rahman
name: Kawahara, Shigenori
Publisher: name: F1000Research
Year: 2015

description: In the present study, behavioral results suggested muscarinic acetyl choline receptors (mAChRs) might play an important role in the formation, but not the expression, of the memory for top-down modulation associated with the feature cue in the serial feature-positive discrimination task in mouse eyeblink conditioning. Analysis of conditioned response (CR) dynamics suggests an involvement of mAChRs in refining CR timing in serial feature-positive discrimination learning.

The similarity in CR peak amplitudes in both trials indicates that once the CR had been triggered, it fully developed irrespective of the trial type, suggesting that the top-down modulation mainly occurred before the execution of the CR, but not during the CR itself. This view is consistent with the earlier onset of CR onset in cued trials, suggesting an increased level of attention to the coming conditioned stimulus (CS) by the light cue, which might serve to gate the input-output relationship in the cerebellum and related brain stem structures.

The local field potential (LFP) data revealed  the different roles of sub-bands of type 2 theta in the acquisition sessions. The higher band (7-9 Hz), but not the lower band (4-6Hz), was enhanced across the sessions and further by the cue. Moreover, the lower sub-band but not the higher sub-band showed a steeper rising tendency particularly around the CS in non-cued trial and the higher sub-band was significantly enhanced before the CS in cued trials than in non-cued trials. Also, we observed that cue altered the spectral pattern of the theta from lower-band dominance to higher-band dominance which was further correlated with the earlier onset of the CR, suggesting the higher band of theta reflects the cognition of the conditional cue, leading to the acquisition of the discriminative responses in mice and the lower band of theta reflects an elevation of general attention to the conditioning situation or the behavioral context.

Post-training administration of scopolamine suppressed the elevation of both the lower and higher bands before the cue, but preferentially suppressed the elevation of the higher band after the cue, suggesting that both the sub-bands (i.e. type 2 theta) depend on mAChRs and have different roles in this conditional discrimination learning.
SUSY interpretation of the Egret GeV anomaly, Xenon-10 dark matter search limits and the LHC

description: The observation of the Egret experiment of an excess of diffuse gamma rays with energies above E_γ=1 GeV has previously been interpreted in the context of the minimal supergravity model (mSUGRA) as coming from neutralino annihilation into mainly b-quarks in the galactic halo, with neutralino mass in the vicinity of 50-70 GeV. We observe that in order to obtain the correct relic abundance of neutralinos in accord with WMAP measurements, the corresponding neutralino-proton direct detection (DD) rates should be in excess of recent limits from the Xenon-10 collaboration. While it does not appear possible to satisfy the Egret, WMAP and Xenon-10 constraints simultaneously within the mSUGRA model, we find that it is easily possible in models with non-universal Higgs soft masses (NUHM). In either case, gluino pair production from m(gluino)\sim 400-500 GeV should occur at large rates at the CERN LHC, and a gluino pair production signal should be visible with just 0.1 fb^{-1} of integrated luminosity. The NUHM interpretation predicts a rather light spectrum of heavy Higgs bosons with m_A\sim 140-200 GeV over the whole parameter space which would interpret Egret data. Spin-independent DD rates are predicted to be just above 10^{-8} pb, within range of the next round of direct dark matter detection experiments.

description: Spin defects in van der Waals materials offer a promising platform for advancing quantum technologies. Here, we propose and demonstrate a powerful technique based on isotope engineering of host materials to significantly enhance the coherence properties of embedded spin defects. Focusing on the recently-discovered negatively charged boron vacancy center ($\mathrm{V}_{\mathrm{B}}^-$) in hexagonal boron nitride (hBN), we grow isotopically purified $\mathrm{h}{}^{10}\mathrm{B}{}^{15}\mathrm{N}$ crystals. Compared to $\mathrm{V}_{\mathrm{B}}^-$ in hBN with the natural distribution of isotopes, we observe substantially narrower and less crowded $\mathrm{V}_{\mathrm{B}}^-$ spin transitions as well as extended coherence time $T_2$ and relaxation time $T_1$. For quantum sensing, $\mathrm{V}_{\mathrm{B}}^-$ centers in our $\mathrm{h}{}^{10}\mathrm{B}{}^{15}\mathrm{N}$ samples exhibit a factor of $4$ ($2$) enhancement in DC (AC) magnetic field sensitivity. For additional quantum resources, the individual addressability of the $\mathrm{V}_{\mathrm{B}}^-$ hyperfine levels enables the dynamical polarization and coherent control of the three nearest-neighbor ${}^{15}\mathrm{N}$ nuclear spins. Our results demonstrate the power of isotope engineering for enhancing the properties of quantum spin defects in hBN, and can be readily extended to improving spin qubits in a broad family of van der Waals materials.

description: In the so-called "global polytropic model", we assume planetary systems in hydrostatic equilibrium and solve the Lane--Emden equation in the complex plane. We thus find polytropic spherical shells providing hosting orbits to planets. On the basis of this model, we develop a numerical method which has three versions. In its three-dimensional version, the method is effective for systems with substantial uncertainties in the observed host star radius, and in the orbit of a particular planet (compared to the uncertainties in the orbits of the other planets); the method uses as fixed entry values the observed orbits of the remaining planets. In its two-dimensional version, the method is effective for systems with substantial uncertainty in the host star radius; in this case, the method uses as fixed entry values the observed orbits of the planets. The one-dimensional version was previously developed and applied to several systems; in this version, the observed values of the host star radius and of the planetary orbits are taken as fixed entry values. Our method can compute optimum values for the polytropic index of the global polytropic model which simulates the exoplanetary system, for the orbits of the planets, and (excluding the one-dimensional version) for the host star radius.

description: Edinburgh Cognitive and Behavioural ALS Screen (ECAS) is a brief, standardized assessment of cognitiveimpairment inamyotrophic lateral sclerosis. Objective: We aimed to createa normative dataset for the ECAS Czech version (ECAS-CZ) in order to make the assessment applicable for clinical settings. Method: Included were 102 healthy participants (mean age: 54.92 ± 14.55; education: 14.52 ± 2.44; 54:48 females/males) that fulfilled rigorous exclusion criteria and controlled for depressive symptoms. Results: The internal consistency of ECAS-CZ was acceptable (Cronbach’s α = .69). We found medium correlations (rho ≈ .5) of age and education with ECAS-CZ Total score but not with gender. Cut-offs with −2 SD’s threshold are presented for the differentiation of cognitive impairment. We report percentile values for ECAS-CZ Total including all subscales. Conclusion: We provide normative values for ECAS-CZ that are well suited for the detection of cognitive impairment in clinical settings especially for patients with ALS.

This research investigated the climate system’s response to large volcanic eruptions in the Community Earth System Model-Large Ensemble (CESM-LE). Using 29 CESM-LE global simulations with each ensemble member having a unique prediction about the weather and how climate will change; the climate system's response to large volcanic eruptions could be better understood against the natural variability of the climate model. This is important for developing better predictions of how such events can affect the atmosphere, oceans, cryosphere, and biosphere and for helping people and communities develop mitigations and adaptations to volcanic impacts. This analysis involved examining three large 20th century eruptions, Mount Agung, El Chichón, and Mount Pinatubo and their effect on climate in the CESM-LE ensemble members. Anomalies and standard deviations were distinguished and calculated from the ensemble means of three climate variables: surface temperature, precipitation, and surface pressure. The analysis focused on surface temperature anomalies to look at possible climate responses: global cooling, Northern Hemisphere (NH) winter warming, and changes in El Niño Southern Oscillation (ENSO) events. The first task was to determine if the observed model could produce the well-known and expected global cooling effect. Once that was established the research could confidently explore the two other less clear responses of NH winter warming and ENSO events. The task turned into analyzing if the model would produce NH winter warming or a correlation between volcanic eruptions and ENSO events. The model does produce dramatic decreases in temperature at the time of the eruption, but so far has not been able to produce NH winter warming as a robust climate response. The model does hint at an increased likelihood of ENSO events following large volcanic eruptions.

description: We study a one-dimensional spin-$1/2$ model with three-spin interactions and a transverse magnetic field $h$. The model has a $Z_2 \times Z_2$ symmetry, and a duality between $h$ and $1/h$. The self-dual point at $h=1$ is a quantum critical point with a continuous phase transition. We compute the critical exponents $z$, $β$, $γ$ and $ν$, and the central charge $c$ numerically using exact diagonalization (ED) for systems with periodic boundary conditions. We find that both $z$ and $c$ are equal to $1$, implying that the critical point is governed by a conformal field theory. The values obtained for $β/ν$, $γ/ν$, and $ν$ from ED suggest that the model exhibits Ashkin-Teller criticality with an effective coupling that is intermediate between the four-state Potts model and two decoupled transverse field Ising models. An analysis on larger systems but with open boundaries using density-matrix renormalization group calculations, however, shows that the self-dual point may be in the same universality class as the four-state Potts model. An energy level spacing analysis shows that the model is not integrable. For a system with periodic boundary conditions, there are an exponentially large number of exact mid-spectrum zero-energy eigenstates. A subset of these eigenstates have wave functions which are independent of $h$ and have unusual entanglement structure, suggesting that they are quantum many-body scars. The number of such states scales at least linearly with system size. Finally, we study the infinite-temperature autocorrelation functions close to one end of an open system. We find that some of the autocorrelators relax anomalously in time, with pronounced oscillations and very small decay rates if $h \gg 1$ or $h \ll 1$. If $h$ is close to the critical point, the autocorrelators decay quickly to zero except for an autocorrelator at the end site.

description: In this work, we present the inverted harmonic oscillator (IHO) Hamiltonian as a paradigm to understand the quantum mechanics of scattering and time-decay in a diverse set of physical systems. As one of the generators of area preserving transformations, the IHO Hamiltonian can be studied as a dilatation generator, squeeze generator, a Lorentz boost generator, or a scattering potential. In establishing these different forms, we demonstrate the physics of the IHO that underlies phenomena as disparate as the Hawking-Unruh effect and scattering in the lowest Landau level(LLL) in quantum Hall systems. We derive the emergence of the IHO Hamiltonian in the LLL in a gauge invariant way and show its exact parallels with the Rindler Hamiltonian that describes quantum mechanics near event horizons. This approach of studying distinct physical systems with symmetries described by isomorphic Lie algebras through the emergent IHO Hamiltonian enables us to reinterpret geometric response in the lowest Landau level in terms of relativistic effects such as Wigner rotation. Further, the analytic scattering matrix of the IHO points to the existence of quasinormal modes (QNMs) in the spectrum, which have quantized time-decay rates. We present a way to access these QNMs through wave packet scattering, thus proposing a novel effect in quantum Hall point contact geometries that parallels those found in black holes.

description: Transport properties of manganese oxides suggest that their colossal magnetoresistance (CMR) is due to percolation between ferromagnetic metallic (FM) clusters in an antiferromagnetic insulating (AFI) matrix. We have studied small-angle neutron scattering under applied magnetic field in CMR Pr1-xCaxMnO3 crystals for x around 0.33. Quantitative analysis of the small-angle magnetic neutron scattering shows that the magnetic heterogeneities take place at different scales. At the mesoscopic scale (200nm), the inhomogeneities correspond to the percolation of the conducting ferromagnetic phase into the insulating phases. It is at the origin of the colossal magnetoresistance of the compound. The other inhomogeneities are nanoscopic: inside the antiferromagnetic phase (AFI), there exist small ferromagnetic clusters. Inside the ferromagnetic phase which exists in absence of magnetic field in some compounds and is in fact insulating (FI), there also exist small non ferromagnetic objects. No evolution of this nanostructure is observed when the magnetic field is applied. The existence of such nanoscale objects is discussed in relation to the cationic disorder of these compounds.

Accumulation of CO2 impacts climate resulting in an increase of global temperatures. It is vital to know the underlying processes driving the uptake of CO2 emissions by the biosphere and oceans to infer the rate at which CO2 concentrations will increase in the atmosphere. In this paper, we compare vertical profiles of carbon dioxide concentrations from aircraft measurements to simulated CO2 concentrations from an atmospheric inverse model simulation. The inverse model simulations are based on assimilation ofatmospheric CO2 observations from: (a) the Greenhouse gases Observing SATellite (GOSAT) instrument, (b) the NOAA/ESRL surface flask network, and (c) the Total Carbon Column Observing Network. Since the inverse model simulations generate CO2 fluxes at ~1 degree, these are then fed into an atmospheric transport model to simulate the atmospheric CO2 concentrations. The independent set of aircraft measurements are obtained from a suite of NOAA/ESRL and the HIAPER pole-to-pole flight campaigns (HIPPO-3 and HIPPO-5 field phases). Both qualitative and quantitative analyses are used to evaluate the quality of the simulated CO2 concentrations from the inverse modeling approach. Results show: (a) a greater difference between the aircraft and the inverse modeling simulated CO2 concentrations over land regions relative to over ocean basins, and (b) the inverse simulations under-estimate in the winter and over-estimate in the summer. Both of these differences can be attributed to the greater variability and heterogeneity in the CO2 signal near the land surface, which does not get simulated well by the inverse modeling approach. Future work will examine possible ways to improve the inverse model simulations in order to obtain better agreement with the aircraft data.

description: In this work, we analyze the circumstances under which social influence operations are likely to succeed. These circumstances include the selection of Confederate agents to execute intentional perturbations and the selection of Perturbation strategies. We use Agent-Based Modelling (ABM) as a simulation technique to observe the effect of intentional stance perturbations on scale-free networks. We develop a co-evolutionary social influence model to interrogate the tradeoff between perturbing stance and maintaining influence when these variables are linked through homophily. In our experiments, we observe that stances in a network will converge in sufficient simulation timesteps, influential agents are the best Confederates and the optimal Perturbation strategy involves the cascade of local ego networks. Finally, our experimental results support the theory of tipping points and are in line with empirical findings suggesting that 20-25% of agents need to be Confederates before a change in consensus can be achieved.

description: Julian Schwinger's influence on twentieth century science is profound and pervasive. Of course, he is most famous for his renormalization theory of quantum electrodynamics, for which he shared the Nobel Prize with Richard Feynman and Sin-itiro Tomonaga. But although this triumph was undoubtedly his most heroic work, his legacy lives on chiefly through subtle and elegant work in classical electrodynamics, quantum variational principles, proper-time methods, quantum anomalies, dynamical mass generation, partial symmetry, and more. Starting as just a boy, he rapidly became the pre-eminent nuclear physicist in the late 1930s, led the theoretical development of radar technology at MIT during World War II, and then, soon after the war, conquered quantum electrodynamics, and became the leading quantum field theorist for two decades, before taking a more iconoclastic route during his last quarter century.
