description: We present new limits on the graviton mass using a sample of 12 relaxed galaxy clusters, for which temperature and gas density profiles were derived by Vikhlinin et al (astro-ph/0507092) using Chandra X-ray observations. These limits can be converted to a bound on the graviton mass, assuming a non-zero graviton mass would lead to a Yukawa potential at these scales. For this purpose, we first calculate the total dynamical mass from the hydrostatic equilibrium equation in Yukawa gravity and then compare it with the corresponding mass in Newtonian gravity. We calculate a 90 % c.l. lower/upper limit on the graviton Compton wavelength/ mass for each of the 12 clusters in the sample. The best limit is obtained for Abell 2390, corresponding to $λ_g > 3.58\times 10^{19}$ km or $m_g<3.46 \times 10^{-29}$ eV. This is the first proof of principles demonstration of setting a limit on the graviton mass using a sample of related galaxy clusters with X-ray measurements and can be easily applied to upcoming X-ray surveys such as eRosita.

description: Synthetic oxidative hair dyes available in the market contain a combination of peroxide and ammonia. In addition, people who use synthetic dyes are at risk for skin burns, irritation to the eye and also lead to cancer. Hence, herbal-based hair dyes are safe to use. In the traditional system of medicine, different parts of Phyllanthus reticulatus were used for curing various ailments. The aqueous leaf extract showed the presence of phytochemical rich components. Herbal hair dye has been formulated by using P. reticulatus with various natural ingredients in the ratio of 5:1:1:1:1. The herbal hair dye was evaluated for its various parameters. It showed potent in vitro antimicrobial activity against various microorganisms and antioxidant activity. In the formulated product, the natural ingredients are known for their non-toxic properties and there are no added chemicals and preservatives. It offers a natural alternative, that can be used irrespective of any side effects.

description: As shown recently, one can obtain additional information from the measured multiplicity distributions, $P(N)$, by extracting the so-called modified combinants, $C_j$. This information is encoded in their specific oscillatory behavior, which can be described only by some combinations of compound distributions, the basic part of which is the Binomial Distribution. So far this idea was applied to $pp$ and $p\bar{p}$ processes; in this note we show that an even stronger effect is observed in the $C_j$ deduced from $e^+e^-$ collisions. We present its possible explanation in terms of the so called Generalised Multiplicity Distribution (GMD) proposed some time ago.

description: Brownian motion with coordinate dependent damping and diffusivity is ubiquitous. Understanding equilibrium of a Brownian particle with coordinate dependent diffusion and damping is a contentious area. In this paper, we present an alternative approach based on already established methods to this problem. We solve for the equilibrium distribution of the over-damped dynamics using Kramers-Moyal expansion. We compare this with the over-damped limit of the generalized Maxwell-Boltzmann distribution. We show that the equipartition of energy helps recover the Stokes-Einstein relation at constant diffusivity and damping of the homogeneous space. However, we also show that, there exists no homogeneous limit of coordinate dependent diffusivity and damping with respect to the applicability of Stokes-Einstein relation when it does not hold locally. In the other scenario where the Stokes-Einstein relation holds locally, one needs to impose a restriction on the local maximum velocity of the Brownian particle to make the modified Maxwell-Boltzmann distribution coincide with the modified Boltzmann distribution in the over-damped limit.
description: 8 pages and no figures. This version includes an extra section where the situation of the Stokes-Einstein relation holding locally in equilibrium is taken into consideration. The results are essentially for a Brownian particle with coordinate dependent diffusivity

description: Ctenomys roigi
 This lineage corresponds to the species firstly described by Contreras (1988) who pointed out its morphological distinctiveness. This species is distributed in an extremely limited area, within less than 100 km 2, and thus was considered as Critically Endangered in the IUCN Red List of Threatened Species (Bidau et al. 2008a). To date, three nearby populations have been ascribed to Ctenomys roigi: Arroyo Pehuajó, Costa Mansión and Estancia San Luis, located in the northwest extreme of the Corrientes Province (Figure 2). All three populations share a distinctive karyotype, 2n = 48 FN = 80, with a unique FN in the Corrientes group (Ortells et al. 1990, Table 1). Ctenomys roigi is also a well supported lineage in terms of genetic exclusivity, since it forms a unique SSR cluster and also results monophyletic in the mtDNA phylogeny (Table 1, Figure 3).

description: The linear electronic dispersion relation of graphene endows the atomically thin carbon layer with a large intrinsic optical nonlinearity, with regard to both parametric and photothermal processes. While plasmons in graphene nanostructures can further enhance nonlinear optical phenomena, boosting resonances to the technologically relevant mid- and near-infrared (IR) spectral regime necessitates patterning on $\sim10$ nm length scales, for which quantum finite-size effects play a crucial role. Here we show that thermoplasmons in narrow graphene nanoribbons can be activated at mid- and near-IR frequencies with moderate absorbed energy density, and furthermore can drive substantial third-harmonic generation and optical Kerr nonlinearities. Our findings suggest that photothermal excitation by ultrashort optical pulses offers a promising approach to enable nonlinear plasmonic phenomena in nanostructured graphene that avoids potentially invasive electrical gating schemes and excessive charge carrier doping levels.

description: The observed hierarchy of the quark masses is interpreted as a signal for an underlying ``subnuclear democracy'' as the relevant symmetry of the quark mass terms. A simple breaking of the symmetry leads to a mixing between the second and the third family, in agreement with observation. Introducing the mixing between the first and the second family, one finds an interesting pattern of maximal CP--violation as well as a complete determination of the elements of the CKM matrix and of the unitarity triangle.

description: The lack of dense random-access memory is one of the main obstacles to the development of digital superconducting computers. It has been suggested that AVRAM cells, based on the storage of a single Abrikosov vortex, the smallest quantized object in superconductors, can enable drastic miniaturization to the nanometer scale. In this work, we present numerical modeling of such cells using time-dependent Ginzburg-Landau equations. The cell represents a fluxonic quantum dot containing a small superconducting island, an asymmetric notch for vortex entrance, a guiding track, and a vortex trap. We determine the optimal geometrical parameters for operation at zero magnetic field and the conditions for controllable vortex manipulation by short current pulses. We report ultra-fast vortex motion with velocities more than an order of magnitude faster than those expected for macroscopic superconductors. This phenomenon is attributed to strong interactions with the edges of a mesoscopic island, combined with the nonlinear reduction of flux-flow viscosity due to nonequilibrium effects in the track. Our results show that such cells can be scaled down to sizes comparable to the London penetration depth, 100 nm, and can enable ultrafast switching on the picosecond scale with ultra-low energy per operation, 0.1 aJ.

description: Starting from a standard description of an ideal, isentropic fluid, we derive the effective theory governing a gapless non-relativistic mode---the sound mode. The theory, which is dictated by the requirement of Galilei invariance, entails the entire set of hydrodynamic equations. The gaplessness of the sound mode is explained by identifying it as the Goldstone mode associated with the spontaneous breakdown of Galilei invariance. Differences with a superfluid are pointed out.

description: The light-cone (LC) effect imprints the cosmological evolution of the redshifted 21-cm signal $T_{\rm b} ({\hat{\bf{n}}}, ν)$ along the frequency axis which is the line of sight (LoS) direction of an observer. The effect is particularly pronounced during the Epoch of Reionization (EoR) when the mean hydrogen neutral fraction ${\bar{x}_{\rm HI}}(ν)$ falls rapidly as the universe evolves. The multi-frequency angular power spectrum (MAPS) ${{\mathcal C}_{\ell}}(ν_1,ν_2)$ quantifies the entire second-order statistics of $T_{\rm b} ({\hat{\bf{n}}}, ν)$ considering both the systematic variation along $ν$ due to the cosmological evolution and also the statistically homogeneous and isotropic fluctuations along all the three spatial directions encoded in ${\hat{\bf{n}}}$ and $ν$. Here we propose a simple model where the systematic frequency $(ν_1,ν_2)$ dependence of ${{\mathcal C}_{\ell}}(ν_1,ν_2)$ arises entirely due to the evolution of ${\bar{x}_{\rm HI}}(ν)$. This provides a new method to observationally determine the reionization history. Considering a LC simulation of the EoR 21-cm signal, we use the diagonal elements $ν_1=ν_2$ of ${{\mathcal C}_{\ell}}(ν_1,ν_2)$ to validate our model. We demonstrate that it is possible to recover the reionization history across the entire observational bandwidth provided we have the value ${\bar{x}_{\rm HI}}$ at a single frequency as an external input.

description: The human serum albumin (HSA)-drug binding characteristic is directly related to the pharmacokinetic, pharmacodynamic profile and side effect properties of drug. Though much is known about the protein binding characteristics of flavonol, the influence of molecular structure of flavonol and dynamic behaviour of protein conformations have received little attention. Here, we studied the interactions of HSA with flavonols by using molecular docking, molecular dynamics simulations coupled with molecular mechanics- Poisson Boltzmann/generalized Born surface area (MM-PB/GBSA) method. The results demonstrated the probable flavonol-binding position of HSA exist near the large hydrophobic cavity of Sudlow’s site 1; and the predicted binding free energies of HSA-flavonol complexes were consistent with the trend of the experimental data that the binding affinity increased with the growth in number of hydroxyl groups on B-ring, and the van der Waals contribution is the dominated component for the binding; and Quercetin and Myricetin with one or two adjacent hydroxyl groups can exist stably in the binding pocket by strong hydrophobic interactions and extensive hydrogen bond interactions. The present work provides further information on the dynamical behaviors of binding pocket and reasonable binding models for HSA to five flavonols, and the adjacent hydroxyl groups introduced to B-ring might be beneficial to HSA-binding.

description: The distribution of the zeros of the partition function in the complex temperature plane (Fisher zeros) of the two-dimensional Q-state Potts model is studied for non-integer Q. On $L\times L$ self-dual lattices studied ($L\le8$), no Fisher zero lies on the unit circle $p_0=e^{iθ}$ in the complex $p=(e^{βJ}-1)/\sqrt{Q}$ plane for Q<1, while some of the Fisher zeros lie on the unit circle for Q>1 and the number of such zeros increases with increasing Q. The ferromagnetic and antiferromagnetic properties of the Potts model are investigated using the distribution of the Fisher zeros. For the Potts ferromagnet we verify the den Nijs formula for the thermal exponent $y_t$. For the Potts antiferromagnet we also verify the Baxter conjecture for the critical temperature and present new results for the thermal exponents in the range 0

description: Object selection is essential in virtual reality (VR) head-mounted displays (HMDs). Prior work mainly focuses on enhancing and evaluating techniques for selecting a single object in VR, leaving a gap in the techniques for multi-object selection, a more complex but common selection scenario. To enable multi-object selection, the interaction technique should support group selection in addition to the default pointing selection mode for acquiring a single target. This composite interaction could be particularly challenging when using freehand gestural input. In this work, we present an empirical comparison of six freehand techniques, which are comprised of three mode-switching gestures (Finger Segment, Multi-Finger, and Wrist Orientation) and two group selection techniques (Cone-casting Selection and Crossing Selection) derived from prior work. Our results demonstrate the performance, user experience, and preference of each technique. The findings derive three design implications that can guide the design of freehand techniques for multi-object selection in VR HMDs.

description: Extant strategic leadership literature has established the substantial and nuanced implications of narcissism in chief executive officers (CEOs) for firm outcomes, and psychological research on narcissism in groups highlights the importance of narcissism for interpersonal dynamics. However, there is little research on strategic leaders’ narcissism and the CEO–top management team (TMT) interface, especially related to its configuration by way of TMT composition. In this article, we therefore study two issues. First, we examine how CEO narcissism directly affects two aspects of TMT composition—the narcissism of newly appointed TMT members and TMT turnover. Second, we consider the moderating effect of TMT narcissism on the relationship between CEO narcissism and TMT turnover. To be able to test our theory, we develop and extensively validate a novel measure based on LinkedIn profiles that allows us to capture the narcissism of non-CEO executives. We find substantial support for our predictions in a large sample of executives of S&P 1500 corporations across a 5-year time frame. We discuss the contributions and implications of our findings for the literatures on executive narcissism, TMT composition, and the CEO–TMT interface.

description: Bolanthus aziz-sancarii identified in 2019 for the first time is an endemic species of Bolanthus genus belonging to Caryophyllaceae family. Ten compounds were isolated from aerial parts of the plant. The potential antioxidant and anti-inflammatory effects of all four phases (hexane, chloroform, ethyl acetate, and water) from the methanol extract of the plant were investigated. After considering the findings regarding both antioxidant and anti-inflammatory capacities, it was decided to investigate the phytochemical profile of the EtOAc layer of B. aziz-sancarii. An abscisic acid-type sesquiterpene glucoside and nine flavonoid derivatives were isolated from the ethyl acetate fraction of the B. aziz-sancarii methanol extract through the use of column chromatography with silica gel.

description: What is the next step after the data/digital revolution? What do we need the most to reach this aim? How machines can memorize, learn or discover? What should they be able to do to be qualified as "intelligent"? These questions relate to the next generation "intelligent" machines. Probably, these machines should be able to handle knowledge discovery, decision-making and concepts. In this paper, we will take into account some historical contributions and discuss these different questions through an analogy to human intelligence. Also, a general framework for a concept oriented language will be proposed.

description: We study steady-state properties of inelastic gases in two-dimensions in the presence of an energy source. We generalize previous hydrodynamic treatments to situations where high and low density regions coexist. The theoretical predictions compare well with numerical simulations in the nearly elastic limit. It is also seen that the system can achieve a nonequilibrium steady-state with asymmetric velocity distributions, and we discuss the conditions under which such situations occur.

Using science fiction, STEM content, and guided inquiry design to stimulate fifth graders’ situational and individual interest development: case studies during the Pandemic
Creators: name: DuBoff, Bruce
Publisher: name: No Publisher Supplied
Year: 2023

description: Interest in Science, Technology, Engineering, and Mathematics (STEM) education is more important than ever since the Pandemic ravaged our nation’s medical resources and personnel. This exploratory study, intended to establish and characterize potential identifiers and markers of student interest development in an inquiry-driven learning environment, offers middle and high school librarians and teachers of all subjects another tool in their toolbox to teach and promote literacy and interest in STEM subjects and activities. This dissertation project, created to satisfy the requirements of the Rutgers University School of Communications and Information Ph.D. program in Library Information Science, features fifth-graders in an after-school program in New Jersey. It incorporates the integration of Science Fiction and STEM into a Guided Inquiry unit, focusing on the potential triggering, identifying, and observing of STEM and ancillary non-STEM situational and individual interests. Incorporating Design-Based Research (Barab, 2014) and methodological triangulation (Flick, 2018), an online pilot was first conducted in Emergency Remote Teaching conditions with four students in 2020/21. Adjustments were made to the instructional design per the principles of DBR, and a second, 11-week iteration was conducted with 12 students in 2021/22. Student contact was limited and ERT conditions were still in place, though eased to allow in-person instruction. Methodologically, three case studies, pre-and-post, semi-structured interviews, videography with transcription, field observation, and qualitative coding, are utilized to examine the students’ interactions with science fiction and STEM content. Two research questions explore interest development in two areas: Science and STEM, and Science Fiction and other non-STEM topics; e.g. creating projects, global climate change, playing educational games. Observations suggest student activities during inquiry may be related to triggering of both situational and individual interest throughout the Guided Inquiry (Kuhlthau, et al., 2012) unit, revealed through three waves of data analysis. Potential inquiry design enhancements are offered, and additional observations consider future directions in interest development research.
Exact results for the zeros of the partition function of the Potts model on finite lattices

description: The Yang-Lee zeros of the Q-state Potts model are investigated in 1, 2 and 3 dimensions. Analytical results derived from the transfer matrix for the one-dimensional model reveal a systematic behavior of the locus of zeros as a function of Q. For 12 they lie outside the unit circle for finite temperature. In the special case Q=2 the zeros lie exactly on the unit circle as proved by Lee and Yang. In two and three dimensions the zeros are calculated numerically and behave in the same way. Results are also presented for the critical line of the Potts model in an external field as determined from the zeros of the partition function in the complex temperature plane.

Thermal conductivity of polymers: A simple matter where complexity matters

description: Thermal conductivity coefficient $κ$ measures the ability of a material to conduct a heat current. In particular, $κ$ is an important property that often dictates the usefulness of a material over a wide range of environmental conditions. For example, while a low $κ$ is desirable for the thermoelectric applications, a large $κ$ is needed when a material is used under the high temperature conditions. These materials range from common crystals to commodity amorphous polymers. The latter is of particular importance because of their use in designing light weight high performance functional materials. In this context, however, one of the major limitations of the amorphous polymers is their low $κ$, reaching a maximum value of about 0.4 W/Km that is 2--3 orders of magnitude smaller than the standard crystals. Moreover, when energy is predominantly transferred through the bonded connections, $κ\ge 100$ W/Km. Recently, extensive efforts have been devoted to attain a tunability in $κ$ via macromolecular engineering. In this work, an overview of the recent results on the $κ$ behavior in polymers and polymeric solids is presented. In particular, computational and theoretical results are discussed within the context of complimentary experiments. Future directions are also highlighted.
Electroweak Phase Transitions in left-right symmetric models

description: We study the finite-temperature effective potential of minimal left-right symmetric models containing a bidoublet and two triplets in the scalar sector. We perform a numerical analysis of the parameter space compatible with the requirement that baryon asymmetry is not washed out by sphaleron processes after the electroweak phase transition. We find that the spectrum of scalar particles for these acceptable cases is consistent with present experimental bounds.

Coherence and asymmetry cannot be broadcast

name: Mueller, Markus P.
Publisher: name: arXiv
Year: 2018
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In the presence of conservation laws, superpositions of eigenstates of the corresponding conserved quantities cannot be generated by quantum dynamics. Thus, any such coherence represents a potentially valuable resource of asymmetry, which can be used, for example, to enhance the precision of quantum metrology or to enable state transitions in quantum thermodynamics. Here we ask if such superpositions, already present in a reference system, can be broadcast to other systems, thereby distributing asymmetry indefinitely at the expense of creating correlations. We prove a no-go theorem showing that this is forbidden by quantum mechanics in every finite-dimensional system. In doing so we also answer some open questions in the quantum information literature concerning the sharing of timing information of a clock and the possibility of catalysis in quantum thermodynamics. We also prove that even weaker forms of broadcasting, of which Aberg's `catalytic coherence' is a particular example, can only occur in the presence of infinite-dimensional reference systems. Our results set fundamental limits to the creation and manipulation of quantum coherence and shed light on the possibilities and limitations of quantum reference frames to act catalytically without being degraded.

description: The influence of a c(2x2) ordered interface alloy of 3d transition metals at the ferromagnet/nonmagnet interface on interlayer exchange coupling (IXC), the formation of quantum well states (QWS) and the phenomenon of Giant MagnetoResistance is investigated. We obtained a strong dependence of IXC on interface alloy formation. The GMR ratio is also strongly influenced. We found that Fe, Ni and Cu alloys at the interface enhance the GMR ratio for in-plane geometry by nearly a factor of 2.

Matrix product states approaches to operator spreading in ergodic quantum systems

description: We review different tensor network approaches to study the spreading of operators in generic nonintegrable quantum systems. As a common ground to all methods, we quantify this spreading by means of the Frobenius norm of the commutator of a spreading operator with a local operator, which is usually referred to as the out of time order correlation (OTOC) function. We compare two approaches based on matrix-product states in the Schrödinger picture: the time dependent block decimation (TEBD) and the time dependent variational principle (TDVP), as well as TEBD based on matrix-product operators directly in the Heisenberg picture. The results of all methods are compared to numerically exact results using Krylov space exact time evolution. We find that for the Schrödinger picture the TDVP algorithm performs better than the TEBD algorithm. Moreover the tails of the OTOC are accurately obtained both by TDVP MPS and TEBD MPO. They are in very good agreement with exact results at short times, and appear to be converged in bond dimension even at longer times. However the growth and saturation regimes are not well captured by both methods.

Dynamics of compressible edge and bosonization

Year: 1996
Subjects: subject: Condensed Matter (cond-mat)

description: We work out the dynamics of the compressible edge of the quantum Hall system based on the electrostatic model of Chklovskii et al.. We introduce a generalized version of Wen's hydrodynamic quantization approach to the dynamics of sharp edge and rederive Aleiner and Glazman's earlier result of multiple density modes. Bosonic operators of density excitations are used to construct fermions at the interface of the compressible and incompressible region. We also analyze the dynamics starting with the second-quantized Hamiltonian in the lowest Landau level and work out the time development of density operators. Contrary to the hydrodynamic results, the density modes are strongly coupled. We argue that the coupling suppresses the propagation of all acoustic modes, and that the excitations with large wavevectors are subject to decay due to coupling to the dissipative acoustic modes.A possible correction to the tunneling density of states is discussed.

description: We report the realization of a heteronuclear two-atom of $^{87}$Rb-$^{85}$Rb in the ground state of an optical tweezer (OT). Starting by trapping two different isotopic single atoms, a $^{87}$Rb and a $^{85}$Rb in two strongly focused and linearly polarized OT with 4 $μ$m apart, we perform simultaneously three dimensional Raman sideband cooling for both atoms and the obtained 3D ground state probabilities of $^{87}$Rb and $^{85}$Rb are 0.91(5) and 0.91(10) respectively. There is no obvious crosstalk observed during the cooling process. We then merge them into one tweezer via a species-dependent transport, where the species-dependent potentials are made by changing the polarization of the OTs for each species from linear polarization to the desired circular polarization. The measurable increment of vibrational quantum due to merging is $0.013(1)$ for the axial dimension. This two-atom system can be used to investigate cold collisional physics, to form quantum logic gates, and to build a single heteronuclear molecule. It can also be scaled up to few-atom regime and extended to other atomic species and molecules, and thus to ultracold chemistry.
