Abstract

The short-tailed albatross Phoebastria albatrus, a globally Vulnerable species recovering from near-extinction, breeds mainly on 2 island groups in the north-western Pacific: Torishima and Senkaku Islands. Recently, it became clear that this is a species complex, composed of 2 populations (‘Torishima’ and ‘Senkaku’ types) that are distinct from both genetic and morphological perspectives, and which mate assortatively on Torishima. We tested the hypothesis of premating isolation as a possible mechanism for genetic differentiation and shifted breeding date in short-tailed albatrosses. Using light-based geolocation and molecular analysis, we examined whether adults from the 2 populations breeding on Torishima differed in their at-sea distribution during the nonbreeding period (June-September) and in their return dates. From 22 bird tracks collected from 12 birds over 4 yr, we identified 2 distinct nonbreeding areas: around the Aleutian Islands in the Bering Sea and near the Kuril Islands in the Okhotsk Sea. All 6 tracks of Torishima-type birds migrated directly to the Bering Sea in all years. In contrast, most of the Senkaku-type birds migrated along northeast Japan to the Okhotsk Sea (9 tracks), with the others moving to the Bering Sea (7 tracks). There was no clear difference in the dates of return to Torishima between the 2 bird types. Overall, no absolute pre-mating isolation in space or time was observed in short-tailed albatrosses, but we highlighted notable divergences in the nonbreeding distribution of both types. This result suggests that Torishima- and Senkaku-type populations should be treated as separate management units.

Abstract

We present direct photon-hadron correlations in 200 GeV/A Au+Au, d+Au, and p+p collisions, for direct photon pT from 5–12 GeV/c, collected by the PHENIX Collaboration in the years from 2006 to 2011. We observe no significant modification of jet fragmentation in d+Au collisions, indicating that cold nuclear matter effects are small or absent. Hadrons carrying a large fraction of the quark's momentum are suppressed in Au+Au compared to p+p and d+Au. As the momentum fraction decreases, the yield of hadrons in Au+Au increases to an excess over the yield in p+p collisions. The excess is at large angles and at low hadron pT and is most pronounced for hadrons associated with lower momentum direct photons. Comparison to theoretical calculations suggests that the hadron excess arises from medium response to energy deposited by jets.

Abstract

The prefrontal cortex (PFC) is sensitive to the stress exposure and involved in stress coping. And the effects of gum chewing on the stress have been studied using NIRS. However, when measuring NIRS on PFC during gum chewing, blood flows in shallow tissues (scalp, skin, muscle) might be affected. A NIRS used in the present study first, which has a short distance (1 cm) and the usual (3 cm) source-detector (S-D) regression, can allow eliminating shallow tissues effect of gum chewing. The aim of this study was to investigate the hypothesis that gum chewing activates the right prefrontal cortex (PFC) in stress coping against negative sounds (NS) from the International Affective Digitized Sounds-2 (IADS) as a mental stress task. NS showed activation in the right PFC. There was a significant difference between NS, and NS with Gum, where NS with Gum showed an increased PFC activity, increased alpha wave appearance rate, a higher value in heart rate level, and a higher VAS score indicating 'pleasant'. Gum chewing activated right PFC activity while exposed to negative sounds from IADS as a mental stress task.

Abstract

In the fully superconducting synchronous motors using REBCO tapes, the magnetic fields in the direction of perpendicular to the face of the tapes in armature windings generate large ac losses in the windings. Therefore, it is effective to reduce magnetic fields in the direction of perpendicular to tape face for the reduction of ac losses. A one of the methods is to get closer a yoke to the armature windings as possible. However, installing the yoke in the cooling area in order to get closer the yoke to the armature windings substantially increase the iron loss in the yoke by the cooling penalty. Therefore, in general, the yoke is placed at room temperature. The purpose of this paper is to evaluate the effect of installing the yoke in low temperature. So, we analyzed the properties of 500-kW fully superconducting synchronous motor by finite element method. We estimated the influences of installing yoke into low temperature in the two cases of armature winding shapes, solenoid windings and pancake windings. In this calculation, we assumed that superconducting material is EuBCO, and the operating temperature is 65 K.

Abstract

This study designed various 2-MW fully superconducting motors with the recently developed REBa 2 Cu 3 O 7-δ (RE: Rare Earth, Y, Gd, Eu, REBCO) superconducting tapes to determine an optimum structure. The ac loss and critical current properties of the REBCO tapes were investigated and adopted in the design and analysis of the motor. The motors were designed by setting the operating temperature and the magnitude of magnetic field at the gap as parameters, and the properties of each motor were evaluated through numerical simulations with commercially available two-dimensional analysis software. Various factors, such as ac loss in the windings, efficiency, and the length of the required REBCO tapes, were evaluated, and the dependence of these factors on the operating temperature T, magnetic loading B g , and diameter of motor D were analyzed. The ac loss induced in the armature windings could be reduced by our original technique, which involves scribing into a multifilamentary structure and special winding of the tapes. As a result, the motor could achieve an efficiency of 97.2% under optimum conditions, in which the REBCO tape is scribed into a 10-filament structure. Setting lower B g and higher T is more favorable for enhancing efficiency, whereas the condition of lower B g and T is more favorable for achieving compactness and lightness.

Abstract

Superconducting magnets for MRI operating in subcooled liquid nitrogen at 65 K are aggressively developed with Re 1 Ba 2 Cu 3 O 7-δ (REBCO, Re:Rare Earth such as Y, Gd, and Eu) superconducting tapes. Superconducting magnets for MRI generally need uniformity of magnetic field within parts per million (ppm) order in time and space. The disturbance is mainly caused by the shielding current induced in the wound REBCO tapes. In this study, to solve that, multifilamentization of REBCO tapes by scribing is introduced. Two pieces of small test coils with the same dimensions and parameters were wound with nonscribed and scribed EuBCO tapes into a four-filament structure. After cooling each test coil with subcooled liquid nitrogen at 65 K and applying bias magnetic field of 0-2 T, transport current was applied step by step with an interval of several tens ampere. Magnetic field variation at the coil center was observed. Though magnetic field followed the variation of transport current with a delay in the respective coils, scribing brought about not only reduction, but also quick decay of shielding current. For quantitative analysis, a fitting expression for the observed field variations was derived and discussed.

Abstract

The PHENIX collaboration presents first measurements of low-momentum ($0.4$1\,GeV/$c$) direct-photon yield $dN_{\gamma}^{\rm dir}/d\eta$ is a smooth function of $dN_{\rm ch}/d\eta$ and can be well described as proportional to $(dN_{\rm ch}/d\eta)^\alpha$ with $\alpha{\approx}1.25$. This scaling behavior holds for a wide range of beam energies at the Relativistic Heavy Ion Collider and the Large Hadron Collider, for centrality selected samples, as well as for different, $A$$+$$A$ collision systems. At a given beam energy the scaling also holds for high $p_T$ ($>5$\,GeV/$c$) but when results from different collision energies are compared, an additional $\sqrt{s_{_{NN}}}$-dependent multiplicative factor is needed to describe the integrated-direct-photon yield., Comment: 673 authors from 82 institutions, 10 pages, 4 figures. v2 is version accepted for publication in Physical Review Letters.

Abstract

The development of fully superconducting motors using $\text{Re}_{1}\text{Ba}_{2}\text{Cu}_{3}\text{O}_{7-\delta}$ (REBCO, Re: rare earth such as Y, Gd, or Eu) superconducting tapes has begun with the support of the Japan Science and Technology Agency. In this study, as the first step, the optimum arrangement of the rotating field winding for a 20-kW 600-r/min fully superconducting motor was evaluated in terms of torque. The ac loss and critical current properties of currently developed REBCO superconducting tapes were first investigated using a pickup coil method. Taking these properties into account, 20-kW fully superconducting motors with four types of ironless two-pole rotors were designed. The ac loss reduction technique for REBCO superconducting tapes, which was successfully adopted for a 66-kV 2-MVA transformer, was applied to the fixed armature winding. By numerically simulating the actual operation of the respective motors, the torque and ac loss properties were investigated. The torque, i.e., the output power of the motor, and the torque ripple were found to strongly depend on the arrangement of the field winding, despite the different arrangements having the same ampere-turn. The torque ripple becomes smaller as the rotating field winding approximates a 2-D dipole, which is indicated by the uniformity of the magnetic field inside the rotor.

Abstract

We are developing superconducting magnets for MRI with $\mbox{Re}_{1}\mathrm{Ba}_{2}\mbox{Cu}_{3}\mbox{O}_{7-\delta}$ (Re: Rare Earth, Y, Gd, Eu, REBCO) superconducting tapes. We intend to operate them in subcooled liquid nitrogen at 65 K. Superconducting magnets for MRI need uniformity of magnetic field in time and space. The disturbance should be mainly caused by the shielding current induced in the wound tapes. To investigate this, we made small test coils with a laser-scribed four-filament EuBCO tape and a nonscribed GdBCO tape. After cooling down to 65 K with subcooled liquid nitrogen and applying a dc bias magnetic field, transport current was applied step by step to the test coil and the magnetic field variation at the coil center was observed. The actual magnetic field followed the variation of transport current with a delay. We derived the fitting expression for the observed field variations. The magnitude and the decay time constant of the shielding current increased with transport current. However, when further increasing transport current close to the critical current, the shielding current decayed quickly. Using this tremendous knowledge, we proposed a new operating method so that the magnetic field reached to the target one in a short time. In addition, the comparison between both coils demonstrated that not only the magnitude of shielding current but also the decay time constant was drastically reduced by scribing.

Abstract

Superconducting magnets for MRI need uniformity of produced magnetic field within ppm order in time and space. To develop the superconducting magnets for MRI operating in subcooled liquid nitrogen at 65 K, two pieces of small test coils were fabricated with Re 1 Ba 2 Cu 3 O 7-δ (REBCO, Re: Rare Earth such as Y, Gd, and Eu) superconducting tapes. One was wound with a nonscribed tape and the other was with a laser-scribed tape into a four-filament structure. Each test coil was inserted inside a NbTi superconducting magnet. After bath cooling, the test coil with subcooled liquid nitrogen and applying a dc bias magnetic field of 0.5-2 T, transport current was applied step by step, and the variation of magnetic field at the coil center was observed by a Hall probe with high accuracy. Although magnetic field followed the variation of transport current with a delay in the respective coils, the drastic difference between them was revealed. It was demonstrated that the influence of the induced shielding current on the produced magnetic field was drastically reduced by scribing. Not only the magnitude of shielding current but also the decay time constant was reduced by scribing. The produced magnetic field of the test coil with the scribed tape reached to a target one in a short time as programmed. Scribing REBCO tapes brought about faster relaxation of magnetization.

Abstract

We report a measurement of e+e− pairs from semileptonic heavy-flavor decays in p+p collisions at sNN=200 GeV. The e+e− pair yield from bb¯ and cc¯ is separated by exploiting a double differential fit done simultaneously in dielectron invariant mass and pT. We used three different event generators, pythia, mc@nlo, and powheg, to simulate the e+e− spectra from cc¯ and bb¯ production. The data can be well described by all three generators within the detector acceptance. However, when using the generators to extrapolate to 4π, significant differences are observed for the total cross section. These difference are less pronounced for bb¯ than for cc¯. The same model dependence was observed in already published d+A data. The p+p data are also directly compared with d+A data in mass and pT, and within the statistical accuracy no nuclear modification is seen.

Abstract

10 MW fully superconducting generators, comprising REBCO superconducting tapes with various armature winding configurations, were designed. The influences of these configurations, such as a distributed-winding and a concentrated-winding configuration, on AC loss, output power density, and output voltage waveform were evaluated. As a result, the short-pitch distributed-winding model exhibited the best properties among all the models. In particular, the AC loss of the armature winding was approximately half that of the concentrated winding. Furthermore, the distortion factor was lower than 10%.

Abstract

Measurements of the anisotropic flow coefficients v2{Ψ2},v3{Ψ3},v4{Ψ4}, and v4{Ψ2} for identified particles (π±,K±, and p+p) at midrapidity, obtained relative to the event planes Ψm at forward rapidities in Au + Au collisions at sNN=200GeV, are presented as a function of collision centrality and particle transverse momenta pT. The vn coefficients show characteristic patterns consistent with hydrodynamical expansion of the matter produced in the collisions. For each harmonic n, a modified valence quark-number Nq scaling [plotting vn{Ψm}/(Nq)n/2 versus transverse kinetic energies (KET)/Nq] is observed to yield a single curve for all the measured particle species for a broad range of KET. A simultaneous blast-wave model fit to the observed vn{Ψm}(pT) coefficients and published particle spectra identifies radial flow anisotropies ρn{Ψm} and spatial eccentricities sn{Ψm} at freeze-out. These are generally smaller than the initial-state participant-plane geometric eccentricities n{ΨmPP} as also observed in the final eccentricity from quantum interferometry measurements with respect to the event plane. © 2016 American Physical Society.

Abstract

Jet production rates are measured in p+p and d+Au collisions at sqrt[s_{NN}]=200 GeV recorded in 2008 with the PHENIX detector at the Relativistic Heavy Ion Collider. Jets are reconstructed using the R=0.3 anti-k_{t} algorithm from energy deposits in the electromagnetic calorimeter and charged tracks in multiwire proportional chambers, and the jet transverse momentum (p_{T}) spectra are corrected for the detector response. Spectra are reported for jets with 12

Abstract

Measurements of the fractional momentum loss $({S}_{\mathrm{loss}}\ensuremath{\equiv}\ensuremath{\delta}{p}_{T}/{p}_{T})$ of high-transverse-momentum-identified hadrons in heavy-ion collisions are presented. Using ${\ensuremath{\pi}}^{0}$ in $\mathrm{Au}+\mathrm{Au}$ and $\mathrm{Cu}+\mathrm{Cu}$ collisions at $\sqrt{{s}_{{}_{NN}}}=62.4$ and 200 GeV measured by the PHENIX experiment at the Relativistic Heavy Ion Collider and and charged hadrons in $\mathrm{Pb}+\mathrm{Pb}$ collisions measured by the ALICE experiment at the Large Hadron Collider, we studied the scaling properties of ${S}_{\mathrm{loss}}$ as a function of a number of variables: the number of participants, ${N}_{\mathrm{part}}$, the number of quark participants, ${N}_{\mathrm{qp}}$, the charged-particle density, $d{N}_{\mathrm{ch}}/d\ensuremath{\eta}$, and the Bjorken energy density times the equilibration time, ${\ensuremath{\varepsilon}}_{\mathrm{Bj}}{\ensuremath{\tau}}_{0}$. We find that the ${p}_{T}$, where ${S}_{\mathrm{loss}}$ has its maximum, varies both with centrality and collision energy. Above the maximum, ${S}_{\mathrm{loss}}$ tends to follow a power-law function with all four scaling variables. The data at $\sqrt{{s}_{{}_{NN}}}=200$ GeV and 2.76 TeV, for sufficiently high particle densities, have a common scaling of ${S}_{\mathrm{loss}}$ with $d{N}_{\mathrm{ch}}/d\ensuremath{\eta}$ and ${\ensuremath{\varepsilon}}_{\mathrm{Bj}}{\ensuremath{\tau}}_{0}$, lending insight into the physics of parton energy loss.

Abstract

Measurements of midrapidity charged particle multiplicity distributions, $dN_{\rm ch}/d\eta$, and midrapidity transverse-energy distributions, $dE_T/d\eta$, are presented for a variety of collision systems and energies. Included are distributions for Au$+$Au collisions at $\sqrt{s_{_{NN}}}=200$, 130, 62.4, 39, 27, 19.6, 14.5, and 7.7 GeV, Cu$+$Cu collisions at $\sqrt{s_{_{NN}}}=200$ and 62.4 GeV, Cu$+$Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV, U$+$U collisions at $\sqrt{s_{_{NN}}}=193$ GeV, $d$$+$Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV, $^{3}$He$+$Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV, and $p$$+$$p$ collisions at $\sqrt{s_{_{NN}}}=200$ GeV. Centrality-dependent distributions at midrapidity are presented in terms of the number of nucleon participants, $N_{\rm part}$, and the number of constituent quark participants, $N_{q{\rm p}}$. For all $A$$+$$A$ collisions down to $\sqrt{s_{_{NN}}}=7.7$ GeV, it is observed that the midrapidity data are better described by scaling with $N_{q{\rm p}}$ than scaling with $N_{\rm part}$. Also presented are estimates of the Bjorken energy density, $\varepsilon_{\rm BJ}$, and the ratio of $dE_T/d\eta$ to $dN_{\rm ch}/d\eta$, the latter of which is seen to be constant as a function of centrality for all systems.

Abstract

Jet production rates are measured in p+p and d+Au collisions at sqrt[s_{NN}]=200 GeV recorded in 2008 with the PHENIX detector at the Relativistic Heavy Ion Collider. Jets are reconstructed using the R=0.3 anti-k_{t} algorithm from energy deposits in the electromagnetic calorimeter and charged tracks in multiwire proportional chambers, and the jet transverse momentum (p_{T}) spectra are corrected for the detector response. Spectra are reported for jets with 12p_{T}50 GeV/c, within a pseudorapidity acceptance of |η|0.3. The nuclear-modification factor (R_{dAu}) values for 0%-100% d+Au events are found to be consistent with unity, constraining the role of initial state effects on jet production. However, the centrality-selected R_{dAu} values and central-to-peripheral ratios (R_{CP}) show large, p_{T}-dependent deviations from unity, challenging the conventional models that relate hard-process rates and soft-particle production in collisions involving nuclei.

Abstract

We present the first measurement of elliptic ($v_2$) and triangular ($v_3$) flow in high-multiplicity $^{3}$He$+$Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV. Two-particle correlations, where the particles have a large separation in pseudorapidity, are compared in $^{3}$He$+$Au and in $p$$+$$p$ collisions and indicate that collective effects dominate the second and third Fourier components for the correlations observed in the $^{3}$He$+$Au system. The collective behavior is quantified in terms of elliptic $v_2$ and triangular $v_3$ anisotropy coefficients measured with respect to their corresponding event planes. The $v_2$ values are comparable to those previously measured in $d$$+$Au collisions at the same nucleon-nucleon center-of-mass energy. Comparison with various theoretical predictions are made, including to models where the hot spots created by the impact of the three $^{3}$He nucleons on the Au nucleus expand hydrodynamically to generate the triangular flow. The agreement of these models with data may indicate the formation of low-viscosity quark-gluon plasma even in these small collision systems.

Abstract

We present a systematic study of charged-pion and kaon interferometry in Au + Au collisions at root s(NN) = 200 GeV. The kaon mean source radii are found to be larger than pion radii in the outward and longitudinal directions for the same transverse mass; this difference increases for more central collisions. The azimuthal-angle dependence of the radii was measured with respect to the second-order event plane and similar oscillations of the source radii were found for pions and kaons. Hydrodynamic models qualitatively describe the similar oscillations of the mean source radii for pions and kaons, but they do not fully describe the transverse-mass dependence of the oscillations.

Abstract

We have studied the dependence of azimuthal anisotropy $v_2$ for inclusive and identified charged hadrons in Au$+$Au and Cu$+$Cu collisions on collision energy, species, and centrality. The values of $v_2$ as a function of transverse momentum $p_T$ and centrality in Au$+$Au collisions at $\sqrt{s_{_{NN}}}$=200~GeV and 62.4~GeV are the same within uncertainties. However, in Cu$+$Cu collisions we observe a decrease in $v_2$ values as the collision energy is reduced from 200 to 62.4~GeV. The decrease is larger in the more peripheral collisions. By examining both Au$+$Au and Cu$+$Cu collisions we find that $v_2$ depends both on eccentricity and the number of participants, $N_{\rm part}$. We observe that $v_2$ divided by eccentricity ($\varepsilon$) monotonically increases with $N_{\rm part}$ and scales as ${N_{\rm part}^{1/3}}$. The Cu$+$Cu data at 62.4 GeV falls below the other scaled $v_{2}$ data. For identified hadrons, $v_2$ divided by the number of constituent quarks $n_q$ is independent of hadron species as a function of transverse kinetic energy $KE_T=m_T-m$ between $0.1

Abstract

The PHENIX experiment at RHIC has measured the centrality dependence of the direct photon yield from Au+Au collisions at sNN−−−√=200 GeV down to pT=0.4 GeV/c. Photons are detected via photon conversions to e+e− pairs and an improved technique is applied that minimizes the systematic uncertainties that usually limit direct photon measurements, in particular at low pT. We find an excess of direct photons above the Ncoll-scaled yield measured in p+p collisions. This excess yield is well described by an exponential distribution with an inverse slope of about 240MeV/c in the pT range 0.6–2.0 GeV/c. While the shape of the pT distribution is independent of centrality within the experimental uncertainties, the yield increases rapidly with increasing centrality, scaling approximately with Nαpart, where α=1.38±0.03(stat)±0.07(syst).

We present azimuthal angular correlations between charged hadrons and energy deposited in calorimeter towers in central d+Au and minimum bias p+p collisions at sqrt[s_{NN}]=200 GeV. The charged hadron is measured at midrapidity |η| 2.75 is observed in d+Au collisions. Using the event plane method applied to the Au-going energy distribution, we extract the anisotropy strength v_{2} for inclusive charged hadrons at midrapidity up to p_{T}=4.5 GeV/c. We also present the measurement of v_{2} for identified π^{±} and (anti)protons in central d+Au collisions, and observe a mass-ordering pattern similar to that seen in heavy-ion collisions. These results are compared with viscous hydrodynamic calculations and measurements from p+Pb at sqrt[s_{NN}]=5.02 TeV. The magnitude of the mass ordering in d+Au is found to be smaller than that in p+Pb collisions, which may indicate smaller radial flow in lower energy d+Au collisions.

Abstract

The standard model (SM) of particle physics is spectacularly successful, yet the measured value of the muon anomalous magnetic moment (g−2)μ deviates from SM calculations by 3.6σ. Several theoretical models attribute this to the existence of a “dark photon,” an additional U(1) gauge boson, which is weakly coupled to ordinary photons. The PHENIX experiment at the Relativistic Heavy Ion Collider has searched for a dark photon, U, in π0,η→γe+e− decays and obtained upper limits of O(2×10−6) on U−γ mixing at 90% C.L. for the mass range 30

Abstract

Measurements of bottomonium production in heavy-ion and p + p collisions at the Relativistic Heavy Ion Collider (RHIC) are presented. The inclusive yield of the three states, (1S + 2S + 3S), was measured in the PHENIX experiment via electron-positron decay pairs at midrapidity for Au + Au and p + p collisions at root sNN = 200 GeV. The (1S + 2S + 3S) -> e(+)e(-) differential cross section at midrapidity was found to be B(ee)d sigma/dy = 108 +/- 38 (stat) +/- 15 (syst) +/- 11 (luminosity) pb in p + p collisions. The nuclear modification factor in the 30% most central Au + Au collisions indicates a suppression of the total. state yield relative to the extrapolation from p + p collision data. The suppression is consistent with measurements made by STAR at RHIC and at higher energies by the CMS experiment at the Large Hadron Collider.

Abstract

We present midrapidity charged-pion invariant cross sections, the ratio of the pi(-) to pi(+) cross sections and the charge-separated double-spin asymmetries in polarized p + p collisions at root s = p + 200 GeV. While the cross section measurements are consistent within the errors of next-to-leading-order (NLO) perturbative quantum chromodynamics predictions (pQCD), the same calculations overestimate the ratio of the charged-pion cross sections. This discrepancy arises from the cancellation of the substantial systematic errors associated with the NLO-pQCD predictions in the ratio and highlights the constraints these data will place on flavor-dependent pion fragmentation functions. The charge-separated pion asymmetries presented here sample an x range of similar to 0.03-0.16 and provide unique information on the sign of the gluon-helicity distribution.

Abstract

We report a measurement of e+e− pairs from semileptonic heavy-flavor decays in d+Au collisions at sNN−−−√=200 GeV. By exploring the mass and transverse-momentum dependence of the yield, the bottom decay contribution can be isolated from charm, and quantified by comparison to pythia and mc@nlo simulations. The resulting bb¯-production cross section is σdAubb¯=1.37±0.28(stat)±0.46(syst) mb, which is equivalent to a nucleon-nucleon cross section of σNNbb=3.4±0.8(stat)±1.1(syst)μb.

Abstract

The PHENIX experiment at the Relativistic Heavy Ion Collider has performed a systematic study of K-S(0) and K*(0) meson production at midrapidity in p + p, d + Au, and Cu + Cu collisions at root s(NN) = 200 GeV. The K-S(0) and K*(0) mesons are reconstructed via their K-S(0) -> pi(0)(-> gamma gamma) pi(0)(-> gamma gamma) and K*(0) -> K-+/-pi(-/+) decay modes, respectively. The measured transverse-momentum spectra are used to determine the nuclear modification factor of K-S(0) and K*(0) mesons in d + Au and Cu + Cu collisions at different centralities. In the d + Au collisions, the nuclear modification factor of K-S(0) and K*(0) mesons is almost constant as a function of transverse momentum and is consistent with unity, showing that cold-nuclear-matter effects do not play a significant role in the measured kinematic range. In Cu + Cu collisions, within the uncertainties no nuclear modification is registered in peripheral collisions. In central collisions, both mesons show suppression relative to the expectations from the p + p yield scaled by the number of binary nucleon-nucleon collisions in the Cu + Cu system. In the p(T) range 2-5 GeV/c, the strange mesons (K-S(0), K*(0)) similarly to the phi meson with hidden strangeness, showan intermediate suppression between the more suppressed light quark mesons (pi(0)) and the nonsuppressed baryons (p, (p) over bar). At higher transverse momentum, p(T) > 5 GeV/c, production of all particles is similarly suppressed by a factor of approximate to 2.

Abstract

We developed a turbo-Brayton refrigerator with Ne gas as a working fluid for a 3 - 66/6.9kV-2MVA superconducting transformer with coated conductors which was bath-cooled with subcooled LN2. The two-stage compressor and expansion turbine had non-contact magnetic bearings for a long maintenance interval. In the future, we intend to directly install a heat exchanger into the Glass-Fiber-Reinforced-Plastics cryostat of a transformer and make a heat exchange between the working fluid gas and subcooled LN2. In this paper we investigate the behaviour of subcooled LN2 in a test cryostat, in which heater coils were arranged side by side with a flat plate finned-tube heat exchanger. Here a He turbo-Brayton refrigerator was used as a substitute for a Ne turbo-Brayton one. The pressure at the surface of LN2 in the cryostat was one atmosphere. Just under the LN2 surface, a stationary layer of LN2 was created over the depth of 20 cm and temperature dropped from 77 K to 65 K with depth while, in the lower level than that, a natural convection flow of LN2 was formed and temperature was almost uniform over 1 m depth. The boundary plane between the stationary layer and the natural convection region was visible.

Abstract

Aim: We aimed to assess the amniotic fluid glucose concentration cut-off as an indicator of fetal chromosomal abnormalities, such as trisomy 13, 18, and 21., Methods: This prospective observational study included pregnant females who underwent amniocentesis. Participants were divided into two groups on the border of 22 weeks of gestational age (<22 and ≥22-week groups)., Results: In total, 224 pregnant females were included in the analysis. In the <22 week group, 15 females had trisomies 13/18/21 and 174 females had no trisomies. In the ≥22 week group, 18 females had trisomies 13/18/21 and 17 had no trisomies. In each group, there was a difference in amniotic fluid glucose concentration between fetuses with trisomies 13, 18, and 21 and other fetuses with normal karyotype or minor chromosomal abnormalities. In both groups, the amniotic glucose concentration was noticeably lower in trisomies 13/18/21 (p = 0.002 in the <22 week group; p = 0.039 in the ≥22 week group). According to receiver operating characteristic curves, the optimal cut-off point of glucose concentration was 46 mg/dL in the <22 week group (odds ratio 6.55; 95% confidence interval 1.78-24.1) and 24 mg/dL in the ≥22 week group (odds ratio 8.40; 95% confidence interval 1.83-38.6)., Conclusions: Our study suggested that glucose concentration in amniotic fluid is an indicator of trisomy 13, 18, and 21. Amniotic fluid glucose concentration itself does not diagnose fetal trisomy, but this may be helpful in selecting treatment facilities., (© 2024 Japan Society of Obstetrics and Gynecology.)

Abstract

Microbial rhodopsins are photoreceptive membrane proteins found in microorganisms with an all-trans-retinal chromophore. The function of many microbial rhodopsins is determined by three residues in the third transmembrane helix called motif residues. Here, we report a group of microbial rhodopsins with a novel Thr-Thr-Gly (TTG) motif. The ion-transport assay revealed that they function as light-driven inward anion pumps similar to halorhodopsins previously found in archaea and bacteria. Based on the characteristic glycine residue in their motif and light-driven anion-pumping function, these new rhodopsins are called glycylhalorhodopsins (GHRs). X-ray crystallographic analysis found large cavities on the cytoplasmic side, which are produced by the small side-chain volume of the glycine residue in the motif. The opened structure of GHR on the cytoplasmic side is related to the anion releasing process to the cytoplasm during the photoreaction compared to canonical halorhodopsin from Natronomonas pharaonis (NpHR). GHR also transports SO 4 2- and the extracellular glutamate residue plays an essential role in extracellular SO 4 2- uptake. In summary, we have identified TTG motif-containing microbial rhodopsins that display an anion-releasing mechanism., Competing Interests: Conflict of interest The authors declare that they have no conflicts of interest with the contents of this article., (Copyright © 2024 The Authors.

Abstract

Objectives: There are several types of colorectal cancer (CRC) according to the detection methods and intervals, including interval CRC (iCRC) and postcolonoscopy CRC (PCCRC). We aimed to examine their proportions and characteristics., Methods: We conducted a multicenter prospective study using questionnaires in Japan ("C-DETECT study"), in which differences in CRC characteristics according to detection methods and intervals were examined from consecutive adult patients. Because the annual fecal immunochemical test (FIT) was used in population-based screening, the annual FIT-iCRC was assessed., Results: In total, 1241 CRC patients (1064 with invasive CRC) were included. Annual FIT-iCRC (a), 3-year PCCRC (b), and CRC detected within 1 year after a positive FIT with noncompliance to colonoscopy (c) accounted for 4.5%, 7.0%, and 3.9% of all CRCs, respectively, and for 3.9%, 5.4%, and 4.3% of invasive CRCs, respectively. The comparison among these (a, b, c) and other CRCs (d) demonstrated differences in the proportions of ≥T2 invasion ([a] 58.9%, [b] 44.8%, [c] 87.5%, [d] 73.0%), metastasis ([a] 33.9%, [b] 21.8%, [c] 54.2%, [d] 43.9%), right-sided CRC ([a] 42.9%, [b] 40.2%, [c] 18.8%, [d] 28.6%), and female sex ([a] 53.6%, [b] 49.4%, [c] 27.1%, [d] 41.6%). In metastatic CRC, (a) and (b) showed a higher proportions of BRAF mutations ([a] [b] 12.0%, [c] [d] 3.1%)., Conclusions: Annual FIT-iCRC and 3-year PCCRC existed in nonnegligible proportions. They were characterized by higher proportions of right-sided tumors, female sex, and BRAF mutations. These findings suggest that annual FIT-iCRC and 3-year PCCRC may have biological features different from those of other CRCs., (© 2024 Japan Gastroenterological Endoscopy Society.)

Abstract

Objectives: The initial drug-eluting bead (DEB)-transarterial chemoembolization (TACE) are often performed after multiple sessions of transarterial infusion chemotherapy (TAI) or conventional TACE. The purpose of our study was to evaluate the factors associated with the occurrence of vascular lake phenomenon (VLP) during DEB-TACE, considering the previous interventional treatments., Material and Methods: Forty-nine initial DEB-TACE procedures in 49 patients between November 2010 and April 2024 were included in this retrospective study. VLP was defined as a localized pooling of contrast agents within the tumor in the venous phase of digital subtraction angiography. The laboratory data, pre-treatment imaging findings such as the maximum tumor diameter (≥3 cm or <3 cm) and the presence of enhancing capsule obtained from computed tomography or magnetic resonance imaging, size of DEBs, and loading drugs, the total number of previous interventional treatments were recorded and compared between VLP occurrence and VLP non-occurrence groups. The multivariate logistic regression analysis was performed to explore the association of factors in predicting VLP occurrence., Results: VLP was observed in 16 patients (32.65%) out of 49 patients. The maximum tumor diameter (≥3 cm) and the presence of the enhancing capsule were significantly higher, and the total number of previous interventional treatments was significantly smaller in the VLP occurrence group than in the VLP non-occurrence group ( P = 0.0006, 0.0007, and 0.0003). In multivariate analysis, the maximum tumor diameter, the presence of the enhancing capsule, and the total number of previous interventional treatments were significantly associated with the occurrence of VLP ( P = 0.0048, 0.0093, and 0.047)., Conclusion: Our study confirmed that the reported risk factor, the maximum tumor diameter, and the enhancing capsule were significantly related to the occurrence of VLP in DEB-TACE. Further, the occurrence of VLP might be carefully considered when the number of previous interventional treatments is small., Competing Interests: There are no conflicts of interest., (© 2024 Published by Scientific Scholar on behalf of Journal of Clinical Imaging Science.)

Abstract

Objective: Japan has resumed its health technology assessment to decide how to reduce high-cost drug prices. While drug price rules in Japan are comprehensive, they do not necessarily capture differences in product characteristics. This study examined the drug price revision strategy in Japan using migraine treatment with triptans as an example. Cost data from fiscal years (FY) 2018, 2020, and 2022 were utilized. Methods: A cost-utility analysis was conducted from the perspective of healthcare payers, focusing on Japanese patients aged over 18 years experiencing migraines. The study employed a base-case model with probabilities derived from a network meta-analysis. Direct costs included medical and drug costs. Effectiveness was assessed using the European Quality of Life 5-dimensions-3-level questionnaire. Deterministic and probabilistic sensitivity analyses were conducted to examine the level of uncertainty. Results: In FY2018, sumatriptan and eletriptan were cost-effective; however, the other triptans were dominated by sumatriptan. In FY2020, sumatriptan and eletriptan were cost-effective, and rizatriptan was extended-dominated; nevertheless, the other triptans were dominated by sumatriptan. In FY2022, naratriptan and eletriptan were cost-effective; however, the other triptans were dominated by naratriptan. The hierarchy of triptan strategies varied in each fiscal year. Conclusions: This study provides valuable insights into the drug price revision strategy in Japan. The variations could be problematic because in Japan, formulary management of triptans, for example, those for migraine, may face revaluation every other year. Discussions regarding this issue will be further explored in the future., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Abstract

Microbial pump rhodopsins are highly versatile light-driven membrane proteins that couple protein conformational dynamics with ion translocation across the cell membranes. Understanding how microbial pump rhodopsins use specific amino acid residues at key functional sites to control ion selectivity and ion pumping direction is of general interest for membrane transporters, and could guide site-directed mutagenesis for optogenetics applications. To enable direct comparisons between proteins with different sequences we implement, for the first time, a unique n umbering s cheme for the m icrobial pump rho dopsin residues, NS-mrho . We use NS-mrho to show that distinct microbial pump rhodopsins typically have hydrogen-bond networks that are less conserved than anticipated from the amino acid residue conservation, whereas their hydrophobic interaction networks are largely conserved. To illustrate the role of the hydrogen-bond networks as structural elements that determine the functionality of microbial pump rhodopsins, we performed experiments, atomic-level simulations, and hydrogen bond network analyses on GR, the outward proton pump from Gloeobacter violaceus , and KR2, the outward sodium pump from Krokinobacter eikastus . The experiments indicate that multiple mutations that recover KR2 amino acid residues in GR not only fail to convert it into a sodium pump, but completely inactivate GR by abolishing photoisomerization of the retinal chromophore. This observation could be attributed to the drastically altered hydrogen-bond interaction network identified with simulations and network analyses. Taken together, our findings suggest that functional specificity could be encoded in the collective hydrogen-bond network of microbial pump rhodopsins.

Abstract

Introduction: There is considerable concern about whether endoscopic resection (ER) before additional surgery (AS) for T1 colorectal cancer (CRC) has oncologically potential adverse effects. Therefore, the aim of this study was to compare the long-term outcomes, including overall survival (OS), of patients treated with AS after ER vs primary surgery (PS) for T1 CRC using a propensity score-matched analysis from a large observational study., Methods: This study investigated 6,105 patients with T1 CRC treated with either ER or surgical resection between 2009 and 2016 at 27 high-volume Japanese institutions, with those undergoing surgery alone included in the PS group and those undergoing AS after ER included in the AS group. Propensity score matching was used for long-term outcomes of mortality and recurrence analysis., Results: After propensity score matching, 1,219 of 2,438 patients were identified in each group. The 5-year OS rates in the AS and PS groups were 97.1% and 96.0%, respectively (hazard ratio: 0.72, 95% confidence interval: 0.49-1.08), indicating the noninferiority of the AS group. Moreover, 32 patients (2.6%) in the AS group and 24 (2.0%) in the PS group had recurrences, with no significant difference between the 2 groups (odds ratio: 1.34, 95% confidence interval: 0.76-2.40, P = 0.344)., Discussion: ER before AS for T1 CRC had no adverse effect on patients' long-term outcomes, including the 5-year OS rate. ER is a viable first-line treatment option for endoscopically resectable T1 CRC., (Copyright © 2024 The Author(s).

Abstract

SeviL, a galactoside-binding lectin previously isolated from the mussel Mytilisepta virgata , was demonstrated to trigger apoptosis in HeLa ovarian cancer cells. Here, we show that this lectin can promote the polarization of macrophage cell lines toward an M1 functional phenotype at low concentrations. The administration of SeviL to monocyte and basophil cell lines reduced their growth in a dose-dependent manner. However, low lectin concentrations induced proliferation in the RAW264.7 macrophage cell line, which was supported by the significant up-regulation of TOM22, a component of the mitochondrial outer membrane. Furthermore, the morphology of lectin-treated macrophage cells markedly changed, shifting from a spherical to an elongated shape. The ability of SeviL to induce the polarization of RAW264.7 cells to M1 macrophages at low concentrations is supported by the secretion of proinflammatory cytokines and chemokines, as well as by the enhancement in the expression of IL-6- and TNF-α-encoding mRNAs, both of which encode inflammatory molecular markers. Moreover, we also observed a number of accessory molecular alterations, such as the activation of MAP kinases and the JAK/STAT pathway and the phosphorylation of platelet-derived growth factor receptor-α, which altogether support the functional reprogramming of RAW264.7 following SeviL treatment. These results indicate that this mussel β-trefoil lectin has a concentration-dependent multifunctional role in regulating cell proliferation, phenotype, and death in macrophages, suggesting its possible involvement in regulating hemocyte activity in vivo.

Abstract

Background: Accurate clinical staging is crucial for selection of optimal oncological treatment strategies in non-small cell lung cancer (NSCLC). Although brain MRI, bone scintigraphy and whole-body PET/CT play important roles in detecting distant metastases, there is a lack of evidence regarding the indication for metastatic staging in early NSCLCs, especially ground-grass nodules (GGNs). Our aim was to determine whether checking for distant metastasis is required in cases of clinical T1N0 GGN., Methods: This was a retrospective study of initial staging using imaging tests in patients who had undergone complete surgical R0 resection for clinical T1N0 Stage IA NSCLC., Results: A total of 273 patients with cT1N0 GGNs (n = 183) or cT1N0 solid tumors (STs, n = 90) were deemed eligible. No cases of distant metastasis were detected on initial routine imaging evaluations. Among all cT1N0M0 cases, there were 191 incidental findings on various modalities (128 in the GGN). Most frequently detected on brain MRI was cerebral leukoaraiosis, which was found in 98/273 (35.9%) patients, while cerebral infarction was detected in 12/273 (4.4%) patients. Treatable neoplasms, including brain meningioma and thyroid, gastric, renal and colon cancers were also detected on PET/CT (and/or MRI). Among those, 19 patients were diagnosed with a treatable disease, including other-site cancers curable with surgery., Conclusions: Extensive staging (MRI, scintigraphy, PET/CT etc.) for distant metastasis is not required for patients diagnosed with clinical T1N0 GGNs, though various imaging modalities revealed the presence of adventitious diseases with the potential to increase surgical risks, lead to separate management, and worsen patient outcomes, especially in elderly patients. If clinically feasible, it could be considered to complement staging with whole-body procedures including PET/CT., (© 2024. The Author(s).)

Abstract

Purpose: Ultrasound pupillometry (UP) is a potential alternative to video pupillometry (VP) for assessing changes in patients' pupillary diameter (ΔPD) due to surgical nociception, but the reproducibility of UP and VP has been unclear. We evaluated the reproducibility of nociceptive ΔPD measured with both methods., Subjects and Methods: This prospective observational trial with 15 healthy volunteers aged ≥ 18 years was conducted at a Japanese teaching hospital. The ΔPD due to tetanic stimuli randomly applied at 10-60 mA was measured with VP and UP. The primary outcome was the correlation between the ΔPD measured with VP and that measured with UP. The secondary outcome was the agreement between the methods. We also evaluated ΔPD pattern changes due to the raised pain intensity in each method., Results: The noxious ΔPD values of UP were weakly but significantly correlated with those of VP (Spearman's ρ = 0.38, p < 0.001). A significant constant error was identified between the two measurements (Bland-Altman: mean of the difference in ΔPD (VP - UP), - 0.4 [95% CI: - 0.52 to - 0.28, p < 0.001], generalized estimating equation: a beta estimator of ΔPD: 0.41, [95% CI: 0.26-0.56, p < 0.001]). The ΔPD pattern changes due to the raised tetanic stimuli were almost the same in the two methods., Conclusion: Due to the significant constant error, we consider the reproducibility of the measured ΔPD between UP and VP moderate. Trial registry number UMIN 000047145. Prior to the subjects' enrollment, the trial was registered with the University Hospital Medical Information Network (Principal investigator: Mao Konno, Date of registration: 3.11.2022). https://center6.umin.ac.jp/cgi-open-bin/ctr&#95;e/ctr&#95;view.cgi?recptno=R000053778 ., (© 2024.
