description: Abstract

This research aims to assess the capabilities of market timing and stock selection in the context of the performance of equity mutual funds, with a focus on return risk factors such as inflation and exchange rate. The Treynor-Mazuy Model is adopted as the main analytical framework, allowing researchers to consider the impact of these risk factors on the variables of market timing and stock selection in the performance of equity mutual funds. This research will gather secondary data from mutual fund firms in Indonesia, specifically focusing on the period from 2018 to 2023. The data is assessed via the use of multiple regression analysis utilizing the Eviews software. The aim of this study is to thoroughly examine the efficacy of market timing and stock selection, as well as the impact of return risk factors on the performance of stocks mutual funds throughout the chosen research period. The results of this research suggest that properly predicting the best time to buy or sell stocks does not significantly affect the performance of stock mutual funds. However, the careful selection of certain stocks does really have a substantial influence on their total success. The performance of stock mutual funds is greatly impacted by the market timing skills, especially when inflation acts as a moderator. Accurate prediction of market timing significantly affects the performance of stock mutual funds, especially when the exchange rate acts as a moderator. However, the capacity to choose individual stocks does not have a substantial impact on the performance of stock mutual funds when inflation is considered as a moderator. Nevertheless, the capacity to choose stocks has a substantial effect on the performance of mutual funds when the exchange rate functions as a moderator.

description: The need for strategies able to accurately manipulate quantum dynamics is ubiquitous in quantum control and quantum information processing. We investigate two scenarios where randomized dynamical decoupling techniques become more advantageous with respect to standard deterministic methods in switching off unwanted dynamical evolution in a closed quantum system: when dealing with decoupling cycles which involve a large number of control actions and/or when seeking long-time quantum information storage. Highly effective hybrid decoupling schemes, which combine deterministic and stochastic features are discussed, as well as the benefits of sequentially implementing a concatenated method, applied at short times, followed by a hybrid protocol, employed at longer times. A quantum register consisting of a chain of spin-1/2 particles interacting via the Heisenberg interaction is used as a model for the analysis throughout.

description: In this work, we have studied the isovector giant dipole resonance (IVGDR) in even-even Sm isotopes within time-dependent Hartree-Fock (TDHF) with four Skyrme forces SLy6, SVbas, SLy5 and UNEDF1. The approach we have followed is somewhat similar to the one we did in our previous work in the region of Neodymium (Nd, Z=60) [\href{https://iopscience.iop.org/article/10.1088/1402-4896/ab73d8}{Physica Scripta (2020)}]. We have calculated the dipole strength of $ ^{128-164}\text{Sm}$, and compared with the available experimental data. An overall agreement between them is obtained. The dipole strength in neutron-deficient $ ^{128-142}\text{Sm}$ and in neutron-rich $^{156-164}\text{Sm}$ isotopes are predicted. Shape phase transition as well as shape coexistence in Sm isotopes are also investigated in the light of IVGDR. In addition, the correlation between the quadrupole deformation parameter $β_{2}$ and the splitting $ΔE/ \bar{E}_{m}$ of the giant dipole resonance (GDR) spectra is studied. The results confirm that $ΔE/ \bar{E}_{m}$ is proportional to quadrupole deformation $β_{2}$

description: We provide a review of recent experimental results on the chiral anomaly in Dirac/Weyl semimetals. After a brief introduction, we trace the steps leading to the prediction of materials that feature protected 3D bulk Dirac nodes. The chiral anomaly is presented in terms of charge pumping between the chiral Landau levels of Weyl fermions in parallel electric and magnetic fields. The related chiral magnetic effect and chiral zero sound are described. Current jetting effects, which present major complications in experiments on the longitudinal magnetoresistance, are carefully analyzed. We describe a recent test that is capable of distinguishing these semiclassical artifacts from intrinsic quantum effects. Turning to experiments, we review critically the longitudinal magnetoresistance experiments in the Dirac/Weyl semimetals Na3Bi, GdPtBi, ZrTe5 and TaAs. Alternate approaches to the chiral anomaly, including experiments on non-local transport, thermopower, thermal conductivity and optical pump-probe response are reviewed. In the Supplement, we provide a brief discussion of the chiral anomaly in the broader context of high energy physics and relativistic quantum field theory, as well the anomaly's starring role at the nexus of quantum physics and differential geometry.

description: We carried out Raman measurements on neutron-irradiated and Al-doped MgB$_2$ samples. The irradiation-induced topological disorder causes an unexpected appearance of high frequency spectral structures, similar to those observed in lightly Al-doped samples. Our results show that disorder-induced violations of the selection rules are responsible for the modification of the Raman spectrum in both irradiated and Al-doped samples. Theoretical calculations of the phonon density of states support this hypothesis, and demonstrate that the high frequency structures arise mostly from contributions at ${\bf q}\not=0$ of the E$_{2g}$ phonon mode.

Resolving VLBI correlator ambiguity in the time delay model improves precision of geodetic measurements

description: The modern Very Long Baseline Interferometry (VLBI) relativistic delay model, as documented in the IERS Conventions refers to the time epoch when the signal passes one of two stations of an interferometer baseline (selected arbitrarily from the pair of stations and called the 'reference station', or 'station 1'). This model consists of the previous correlation procedure used before the year 2002. However, since 2002 a new correlation procedure that produces the VLBI group delays referring to the time epoch of signal passage at the geocenter has been used. A corresponding correction to the conventional VLBI model delay has to be introduced. However, this correction has not been thoroughly presented in peer reviewed journals, and different approaches are used at the correlators to calculate the final group delays officially published in the IVS database. This may cause an inconsistency up to 6 ps for ground-based VLBI experiments between the group delay obtained by the correlator and the geometrical model delay from the IERS Conventions used in data analysis software. Moreover, a miscalculation of the signal arrival moment to the 'reference station' could result a larger modelling error (up to 50 ps). The paper presents the justification of the correction due to transition between two epochs elaborated from the Lorentz transformation, and the approach to model the uncertainty of the calculation of the signal arrival moment. The both changes are particularly essential for upcoming broadband technology geodetic VLBI observations.

description: Empirical correlations between the masses of supermassive black holes (SMBHs) and properties of their host galaxies are well-established. Among these is the correlation with the flat rotation velocity of each galaxy measured either at a large radius in its rotation curve or via a spatially-integrated emission line width. We propose here the use of the de-projected integrated CO emission line width as an alternative tracer of this rotation velocity, that has already been shown useful for the Tully-Fisher (luminosity-rotation velocity) relation. We investigate the correlation between CO line widths and SMBH masses for two samples of galaxies with dynamical SMBH mass measurements, with respectively spatially-resolved and unresolved CO observations. The tightest correlation is found using the resolved sample of 24 galaxies as $\log (M_\mathrm{BH}/\mathrm{M_\odot})=(7.5\pm0.1)+(8.5\pm0.9)[\log(W_\mathrm{50}/\sin i \,\mathrm{km\,s}^{-1})-2.7]$, where $M_\mathrm{BH}$ is the central SMBH mass, $W_{50}$ the full-width at half-maximum of a double-horned emission line profile, and $i$ the inclination of the CO disc. This relation has a total scatter of $0.6\,$dex, comparable to those of other SMBH mass correlations, and dominated by the intrinsic scatter of $0.5\,$dex. A tight correlation is also found between the de-projected CO line widths and the stellar velocity dispersions averaged within one effective radius. We apply our correlation to the COLD GASS sample to estimate the local SMBH mass function.

Dielectric anomaly at the orbital order-disorder transition in LaMnO_(3+delta)

description: We report a novel dielectric anomaly around the Jahn-Teller orbital order-disorder transition temperature T_JT in LaMnO_(3+delta). The transition has been characterized by resistivity (rho)versus temperature (T), calorimetry, and temperature-dependent X-ray diffraction studies. Measurements of complex dielectric permittivity epsilon* (= epsilon'-i.epsilon'') over a low-frequency range (1 Hz - 10 MHz)across T_JT reveal a distinct anomaly. This observation, and the reported relatively high static dielectric constant at T = 0 (epsilon0 \~18-20), possibly indicate that the orbital order gives rise to intrinsic polarization that undergoes transition at T_JT. The frequency dispersion of the dielectric response at any given temperature, however, reveals that the dielectric response consists of Maxwell-Wagner component, due to interfaces, within such a low frequency range. The T_JT and the nature of the anomaly in epsilon'(omega,T), epsilon''(omega,T) at T_JT, of course, vary - from a sharp upward feature to a smeared plateau and then a downward trend - depending on the Mn^4+ concentration of the sample. The observation of an intrinsic dielectric response due to long-range orbital order in LaMnO_3 - where no ferroelectric order is possible due to the absence of off-centre distortion in MnO_6 octahedra - may throw a new light onto these classes of materials vis-a-vis multiferroic materials.

The results also extend to the general cases of harmonic measure moments and winding of multiple paths in a star configuration.

description: The currently known Galactic globular cluster population extends out to a maximum galactocentric distance of $\sim$ 145 kpc, with the peculiarity that the outermost clusters predominantly have an inward velocity. Orbit averaging finds that this configuration occurs by chance about $6\%$ of the time, suggesting that several globular clusters with positive radial velocities remain undiscovered. We evaluate the expected number of undiscovered clusters at large distances under the assumption that the cluster population has a smooth radial distribution and is in equilibrium within the Milky Way's virial radius. By comparing the present day kinematic properties of outer clusters to random orbital configurations of the Galactic globular cluster system through orbit averaging, we estimate a likelihood of $73\%$ of there being at least one undiscovered globular cluster within the Milky Way. This estimate assumes the current population is complete out to 50 kpc, and increases to $91\%$ if the population is complete out to 150 kpc. The likelihood of there being two undiscovered clusters is between $60\%$ and $70\%$, with the likelihood of there being three undiscovered clusters being on the order of $50\%$. The most likely scenario is that the undiscovered clusters are moving outwards, which results in the outer cluster population being consistent with an equilibrium state. Searches for distant and possibly quite low concentration and very low metallicity globular clusters will be enabled with upcoming deep imaging surveys.

description: We present a computational method to solve the magnetohydrodynamic equations in spherical geometry. The technique is fully nonlinear and wholly spectral, and uses an expansion basis that is adapted to the geometry: Chandrasekhar-Kendall vector eigenfunctions of the curl. The resulting lower spatial resolution is somewhat offset by being able to build all the boundary conditions into each of the orthogonal expansion functions and by the disappearance of any difficulties caused by singularities at the center of the sphere. The results reported here are for mechanically and magnetically isolated spheres, although different boundary conditions could be studied by adapting the same method. The intent is to be able to study the nonlinear dynamical evolution of those aspects that are peculiar to the spherical geometry at only moderate Reynolds numbers. The code is parallelized, and will preserve to high accuracy the ideal magnetohydrodynamic (MHD) invariants of the system (global energy, magnetic helicity, cross helicity). Examples of results for selective decay and mechanically-driven dynamo simulations are discussed. In the dynamo cases, spontaneous flips of the dipole orientation are observed.

description: A striking discovery in the field of network science is that the majority of real networked systems have some universal structural properties. In generally, they are simultaneously sparse, scale-free, small-world, and loopy. In this paper, we investigate the second-order consensus of dynamic networks with such universal structures subject to white noise at vertices. We focus on the network coherence $H_{\rm SO}$ characterized in terms of the $\mathcal{H}_2$-norm of the vertex systems, which measures the mean deviation of vertex states from their average value. We first study numerically the coherence of some representative real-world networks. We find that their coherence $H_{\rm SO}$ scales sublinearly with the vertex number $N$. We then study analytically $H_{\rm SO}$ for a class of iteratively growing networks -- pseudofractal scale-free webs (PSFWs), and obtain an exact solution to $H_{\rm SO}$, which also increases sublinearly in $N$, with an exponent much smaller than 1. To explain the reasons for this sublinear behavior, we finally study $H_{\rm SO}$ for Sierpinśki gaskets, for which $H_{\rm SO}$ grows superlinearly in $N$, with a power exponent much larger than 1. Sierpinśki gaskets have the same number of vertices and edges as the PSFWs, but do not display the scale-free and small-world properties. We thus conclude that the scale-free and small-world, and loopy topologies are jointly responsible for the observed sublinear scaling of $H_{\rm SO}$.

We present extensive benchmark studies conducted with this package on UMBC's Bluegrit and Bluewave clusters, and NASA-GFSC's Discover cluster systems. Our results show speedup for a single node achieved by Phi Coprocessors relative to the host CPU SandyBridge processors is about a 1.5X improvement, which compares with the studies published by F.Masci (2013) where he obtains a 2-2.5x performance. The performances across 20 CPU nodes of SandyBridge obtains a uniform speedup of 0.5X over Westmere for problem sizes of 10K, 20K and 40K unknowns. With an Infiniband DDR, the performance of Nehalem processors is comparable to Westmere without the interconnect.

description: The geodesic equation encodes test-particle dynamics at arbitrary gravitational coupling, hence retaining all orders in the post-Minkowskian (PM) expansion. Here we explore what geodesic motion can tell us about dynamical scattering in the presence of perturbatively small effects such as tidal distortion and higher derivative corrections to general relativity. We derive an algebraic map between the perturbed geodesic equation and the leading PM scattering amplitude at arbitrary mass ratio. As examples, we compute formulas for amplitudes and isotropic gauge Hamiltonians for certain infinite classes of tidal operators such as electric or magnetic Weyl to any power, and for higher derivative corrections to gravitationally interacting bodies with or without electric charge. Finally, we present a general method for calculating closed-form expressions for amplitudes and isotropic gauge Hamiltonians in the test-particle limit at all orders in the PM expansion.

description: Thin PbTe films (thickness 500 - 600 angstrom), deposited on SrTiO3, have been investigated by electric field effect (EFE). The high resistivity of such thin films warrants a high sensitivity of the EFE method. The SrTiO3 substrate serves as the dielectric layer in the Gate-Dielectric-PbTe structure. Due to the large dielectric constant of SrTiO3, particularly at low temperatures, the electric displacement D in the film reaches the high value of about 10^8 V/cm, and the EFE introduced charge into the PbTe film amounts to ~ 8 microC/cm2. The high D permits to measure the EFE resistance and Hall constant over a wide region of D, revealing the characteristic features of their D-dependence. An appropriate theoretical model has been formulated, showing that, for such films, one can measure the dependence of the Fermi level on D. In fact, we demonstrate that shifting the Fermi level across the gap by varying D, the density-of-states of the in-gape states can be mapped out. Our results show, that the PbTe layers studied, possess a mobility gap exceeding the gap of bulk PbTe.

description: The present research contributed to the limited research on the influence of the unique components of acculturation on the functioning and parenting of immigrant mothers, by adopting a multidimensional approach using the cluster analysis method. The demographic profile, psychological functioning and parenting practices associated with each acculturation style were examined. The sample was comprised of eighty-six families with young children recruited from Chinese organizations and community centers throughout Maryland. Results revealed four acculturation styles: Integrated, Assimilated, Psychologically Marginalized/Behaviorally Integrated, and Separated. Follow-up analyses indicated that Separated mothers were older at immigration, resided in the U.S. for a shorter amount of time, were less educated, and had lower psychological functioning than mothers in the other clusters. There were no significant differences between the styles in authoritative or indigenous parenting practices. Findings highlighted the importance of simultaneously assessing cultural orientations and components of acculturation, and have implications for policymakers and mental health professionals.

description: Recent experimental observation of unexpectedly large current-induced spin-orbit torque in surface oxidized Cu on top of a ferromagnet suggested a possible role of the orbital Rashba effect (ORE). With this motivation, we investigate the ORE from first principles by considering an oxygen monolayer on top of a Cu(111) film. We show that surface oxidization of Cu film leads to gigantic enhancement of the ORE for states near the Fermi surface. The resulting chiral orbital texture in the momentum space is exceptionally strong, reaching $\sim 0.5\hbar$ in magnitude. We find that resonant hybridization between O $p$-states and Cu $d$-states is responsible for the emergence of the ORE. We demonstrate that application of an external electric field generates huge orbital Hall current, which is an order of magnitude larger than the spin Hall current found in heavy metals. This implies that "orbital torque" mechanism may be significant in surface oxidized Cu/ferromagnet structures. It also encourages experimental verification of the orbital texture in surface oxidized Cu through optical measurements such as angle-resolved photoemission spectroscopy.

description: We describe an action principle, within the framework of the Eddington gravity, which incorporates the matter fields in a simple manner. Interestingly, the gravitational field equations derived from this action is identical to the Einstein's equations, in contrast with the earlier attempts in the literature. The cosmological constant arises as an integration constant in this approach. In fact, the derivation of the field equations demands the existence of a non-zero cosmological constant, thereby providing the raison d'être for a non-zero cosmological constant, implied by the current observations. Several features of our approach strongly support the paradigm that gravity is an emergent phenomenon and, in this perspective, our action principle could have a possible origin in the microstructure of the spacetime. We also discuss several extensions of the action principle, including the one which can incorporate torsion in the spacetime. We also show that an Eddington-like action can be constructed to obtain the field equations of the Lanczos-Lovelock gravity.

The current study uses Sarbin's (1970) social role theory as a framework for analyzing the experiences of seven Afghan men who migrated to the U.S. after fleeing war-torn Afghanistan. It emerged that the Afghan-American men in this sample developed a series of adaptive strategies in response to how they located themselves within the four ecologies theorized by Sarbin, namely self-maintenance (physical), social (relational), transcendental (meaning-making) and normative (internalized standards of success). Findings also revealed that experiences in both Afghanistan and the U.S. contributed to how this sample of Afghan men made meaning of their migration and facilitated their adaptation efforts as refugees.

description: The stochastic transport of suspended particles through a periodic pattern of obstacles in microfluidic devices is investigated by means of the Fokker-Planck equation. Asymmetric arrays of obstacles have been shown to induce the continuous separation of DNA molecules of different length. The analysis presented here of the asymptotic distribution of particles in a unit cell of these systems shows that separation is only possible in the presence of a driving force with a non-vanishing normal component at the surface of the solid obstacles. In addition, vector separation, in which different species move, in average, in different directions within the device, is driven by differences on the force acting on the various particles and not by differences in the diffusion coefficient. Monte-Carlo simulations performed for different particles and force fields agree with the numerical solutions of the Fokker-Planck equation in the periodic system.

description: The cytoplasm is highly compartmentalized, but the extent and consequences of subcytoplasmic mRNA localization in non-polarized cells are largely unknown. We determined mRNA enrichment in TIS granules (TGs) and the rough endoplasmic reticulum (ER) through particle sorting and isolated cytosolic mRNAs by digitonin extraction. When focusing on genes that encode non-membrane proteins, we observed that 52% have transcripts enriched in specific compartments. Compartment enrichment correlates with a combinatorial code based on mRNA length, exon length, and 3' UTR-bound RNA-binding proteins. Compartment-biased mRNAs differ in the functional classes of their encoded proteins: TG-enriched mRNAs encode low-abundance proteins with strong enrichment of transcription factors, whereas ER-enriched mRNAs encode large and highly expressed proteins. Compartment localization is an important determinant of mRNA and protein abundance, which is supported by reporter experiments showing that redirecting cytosolic mRNAs to the ER increases their protein expression. In summary, the cytoplasm is functionally compartmentalized by local translation environments.
Spectral gaps in Wasserstein distances and the 2D stochastic Navier--Stokes equations

description: We develop a general method to prove the existence of spectral gaps for Markov semigroups on Banach spaces. Unlike most previous work, the type of norm we consider for this analysis is neither a weighted supremum norm nor an $Ł^p$-type norm, but involves the derivative of the observable as well and hence can be seen as a type of 1-Wasserstein distance. This turns out to be a suitable approach for infinite-dimensional spaces where the usual Harris or Doeblin conditions, which are geared toward total variation convergence, often fail to hold. In the first part of this paper, we consider semigroups that have uniform behavior which one can view as the analog of Doeblin's condition. We then proceed to study situations where the behavior is not so uniform, but the system has a suitable Lyapunov structure, leading to a type of Harris condition. We finally show that the latter condition is satisfied by the two-dimensional stochastic Navier--Stokes equations, even in situations where the forcing is extremely degenerate. Using the convergence result, we show that the stochastic Navier--Stokes equations' invariant measures depend continuously on the viscosity and the structure of the forcing.

THE EFFECTS OF INTERACTIVE AND PASSIVE DISTRACTION ON COLD-PRESSOR PAIN IN PRESCHOOL-AGED CHILDREN

description: Distraction is a pain management technique that has been shown to be successful at reducing pain and behavioral distress in children during invasive medical procedures. According to McCaul and Malott (1984) the more a distraction task requires controlled cognitive processing (versus automatic processing), the less cognitive resources are available to process the pain sensations. Therefore, a more engaging distraction task should be more successful at reducing pain than a passive task. However, this premise has not been thoroughly investigated, particularly for younger children. In general, distraction as a pain management technique is not as successful for younger children. Since younger children are often referred to pediatric psychologists for distress during procedures, it is important to know what types of distraction tasks are developmentally appropriate and will result in less pain behaviors. This study examined if there are differential effects of one dimension of distraction, amount of interaction with the distractor, for healthy preschool aged children during a cold pressor task. It was hypothesized that children would demonstrate longer pain tolerance during the interactive and passive distraction tasks when compared to baseline and that they would demonstrate significantly longer pain tolerance during the interactive distraction when compared to the passive distraction. Within-subjects analyses of 65 healthy children ages 3 to 5 years old demonstrated a significant main effect for experimental condition F(2,118) = 11.52, p < .001, ?p  = .16. Post hoc analyses indicate that children showed significantly higher pain tolerance during the active and passive conditions when compared to baseline (p < .05). There was not a significant difference between the active and passive conditions (p = .98). This study demonstrates that distraction does result in higher pain tolerance when compared to no distraction for healthy preschool-aged children in a non-clinical setting. Interactive distraction was not more beneficial than passive distraction was in this study. The authors discuss the possibility that these findings differ from those of previous studies with older children because of age-related issues such as cognitive development.

description: We show how every bound state of a finite system of identical fermions, whether a ground state or an excited one, defines a density functional. Degeneracies created by a symmetry group can be trivially lifted by a pseudo-Zeeman effect. When complex scaling can be used to regularize a resonance into a square integrable state, a DF also exists.

Anomaly Detection in Data Streams with A-Distance: Effects of Multiple Anomalous Operators on Accuracy

description: Recent research has shown positive outcomes in using the A-Distance metric to evaluate the current state of a planning domain to find anomalies with a low false positive rate. In order to use the A-Distance metric, which compares two arbitrary probability distributions, previous research converted the planning domains from a symbolic representation to a vector representation. Each column of the vector represents a predicate in the domain, which means there are as many data streams as there are predicates. When creating an anomaly, previous work removed a single operator from the planning domain, which causes a shift in the types of problems that can be solved. However, anomalies can affect many operators. In this thesis, an investigation on the effects of multiple anomalous operators on accuracy was conducted. These anomalous operators included adding multiple new operators to the domain under the closed world assumption, deleting multiple existing operators from the domain, and implementing failure rates to the original set of operators in the domain. Additionally, an exploration of three ways to structure the data streams in the interest of further minimizing the false positive rates was carried out. These methods include taking the sum of all values in a vector, taking the sum of the absolute values of their discrete derivatives, and running a Principle Component Analysis (PCA) on the data streams.
