description: In a system with an even number of SU(2) spins, there is an overcomplete set of states--consisting of all possible pairings of the spins into valence bonds--that spans the S=0 Hilbert subspace. Operator expectation values in this basis are related to the properties of the closed loops that are formed by the overlap of valence bond states. We construct a generating function for spin correlation functions of arbitrary order and show that all nonvanishing contributions arise from configurations that are topologically irreducible. We derive explicit formulas for the correlation functions at second, fourth, and sixth order. We then extend the valence bond basis to include triplet bonds and discuss how to compute properties that are related to operators acting outside the singlet sector. These results are relevant to analytical calculations and to numerical valence bond simulations using quantum Monte Carlo, variational wavefunctions, or exact diagonalization.

description: We report on transport measurements in a thin film of the 2D misfit Cobaltite $Ca_{3}Co_{4}O_{9}$. Dc magnetoresistance measurements obey the modified variable range hopping law expected for a soft Coulomb gap. When the sample is cooled down, we observe large telegraphic-like fluctuations. At low temperature, these slow fluctuations have non Gaussian statistics, and are stable under a large magnetic field. These results suggest that the low temperature state is a glassy electronic state. Resistance relaxation and memory effects of pure magnetic origin are also observed, but without aging phenomena. This indicates that these magnetic effects are not glassy-like and are not directly coupled to the electronic part.

description: We present the optical spectra of 338 nearby M dwarfs, and compute their spectral types, effective temperatures ($T_{\mathrm{eff}}$), and radii. Our spectra have been obtained using several optical spectrometers with spectral resolutions that range from 1200 to 10000. As many as 97% of the observed M-type dwarfs have a spectral type of M3-M6, with a typical error of 0.4 sub-type, among which the spectral types M4-M5 are the most common. We infer the $T_{\mathrm{eff}}$ of our sample by fitting our spectra with theoretical spectra from the PHOENIX model. Our inferred $T_{\mathrm{eff}}$ is calibrated with the optical spectra of M dwarfs whose $T_{\mathrm{eff}}$ have been well determined with the calibrations that are supported by previous interferometric observations. Our fitting procedures utilize the VO absorption band (7320-7570 Å) and the optical region (5000-8000 Å), yielding typical errors of 128 K (VO band) and 85 K (optical region). We also determine the radii of our sample from their spectral energy distributions (SEDs). We find most of our sample stars have radii of $

description: We study the interplay of pore-scale mixing and network-scale advection through heterogeneous porous media, and its role for the evolution and asymptotic behavior of hydrodynamic dispersion. In a Lagrangian framework, we identify three fundamental mechanisms of pore-scale mixing that determine large scale particle motion, namely, the smoothing of intra-pore velocity contrasts, the increase of the tortuosity of particle paths, and the setting of a maximum time for particle transitions. Based on these mechanisms, we derive a theory that predicts anomalous and normal hydrodynamic dispersion based on the characteristic pore length, Eulerian velocity distribution and Péclet number.

Finding Galaxy Groups In Photometric Redshift Space: the Probability Friends-of-Friends (pFoF) Algorithm

description: We present a structure finding algorithm designed to identify galaxy groups in photometric redshift data sets: the probability friends-of-friends (pFoF) algorithm. This algorithm is derived by combining the friends-of-friends algorithm in the transverse direction and the photometric redshift probability densities in the radial dimension. The innovative characteristic of our group-finding algorithm is the improvement of redshift estimation via the constraints given by the transversely connected galaxies in a group, based on the assumption that all galaxies in a group have the same redshift. Tests using the Virgo Consortium Millennium Simulation mock catalogs allow us to show that the recovery rate of the pFoF algorithm is larger than 80% for mock groups of at least $2\times10^{13}M_{\sun}$, while the false detection rate is about 10% for pFoF groups containing at least $\sim8$ net members. Applying the algorithm to the CNOC2 group catalogs gives results which are consistent with the mock catalog tests. From all these results, we conclude that our group-finding algorithm offers an effective yet simple way to identify galaxy groups in photometric redshift catalogs.

description: Motivation
In the DREAM 9.5 Prostate Cancer subchallenge 2, we developed predictive models to predict patient outcomes in metastatic castrate-resistant prostate cancer (mCRPC) with subsequent discontinuation of docetaxel therapy.  The input data consist of 131 variables measured across data from three clinical trials, namely, Memorial Sloan Kettering (MSK, 476 patients), Celgene (526 patients), Sanofi (598 patients). The goal is to predict which patients in a fourth clinical trial, AstraZeneca (AZ, 470 patients), would discontinue treatment due to adverse events within 3 months.

Data & Methods
The data cleansing were done separately within each clinical trial and later merged back together. Our data cleansing and pre-processing procedures include imputation of missing data, and removal of clinical variables with a high percentage of missing data. Data augmentation were also performed by converting selected multi-label variables into binary variables.

We observed that univariate feature selection methods did not perform well.  Hence, we adopted a hill-climbing approach that optimized the AUC within 10-fold cross validation of the training data.  We also addressed the issue of imbalanced data (1292 negative and 197 positive samples) by randomly removing negative samples to meet a ratio roughly of 60% negative and 40% positive samples.

We applied random forest using Sanofi as the hold-out, setting the parameters “mtry” to 25% of the number of features and number of trees to 100 times of the number of features. Our predictive model using MSK and Celgene data as the training set and Sanofi data as the test set yielded AUC=0.165, accuracy=0.9, precision=0.21, F1=0.092 and recall=0.06.

Results
Our final submission in predicting the discontinuation of docetaxel in the AstraZeneca clinical trial (using MSK, Celgene and Sanofi as training data) resulted in AUC of 0.13. Across the 470 patients in AstraZeneca clinical trial, 8 patients are predicted to discontinue the treatment within 3 months.

description: DNA polymerase beta is a 39 kDa enzyme that comprises two major domains, a 31 kDa domain responsible for the polymerase activity and an 8 kDa domain, which bind ssDNA and has a dRP Lyase activity. DNA polymerase beta was shown to be phosphorylated in vitro with Protein Kinase C at serines 44 and 55, resulting in loss of its polymerase enzymic activity, but not ability to bind ss DNA. The enzyme has a potential phosphorylation site at tyrosine 250, observed by mass spectroscopy. We set out to simulate potential phosphorylation-induced structural changes for DNA polymerase beta using Molecular Dynamics (MD) simulations (CHARMM22 and AMBER for serines and tyrosine, respectively) and published structural coordinates for the enzyme (pdb: 2FMS). Simulations with CHARMM22 were for 10 ns and with AMBER for 100 ns. RMSF plot of Ser44P showed highest deviation. RMSF plot of Ser55P and Ser44/55P showed a similar fluctuation pattern except at aa 1-75, the major part for ssDNA binding and dRP lyase domains. Radius for gyration (Rg) for apo_enzyme and Ser55P were consistent throughout the simulation. The Rg of Ser44P and Ser44/55P fluctuated throughout the simulation. Phosphorylation at Ser44, Ser55 and Ser44/55 induced major conformational fluctuations from apo_enzyme at the ssDNA binding domain and dNTP selection domain. Tyr250P enzyme was noticeably more dynamic than reference. The results may explain the Protein Kinase C phosphorylation-induced loss of enzymic activity reported in vitro. Data also suggest that phosphorylation at tyrosine 250 is worthy of being investigated. Such studies may pave the way for simulating variations in the atomic structure for the other post- translationally modified (e.g. acetylated) form(s) for this and other enzymes/proteins and be used as an indicator that a potential modification may have structural (and functional) consequences.
Polarization of Quasars: Electron Scattering in the Broad Absorption Line Region

description: It is widely accepted that the broad absorption line region (BALR) exists in most (if not all) quasars with a small covering factor. Recent works showed that the BALR is optically thick to soft and even medium energy X-rays, with a typical hydrogen column density of a few 10$^{23}$ to $>$ 10$^{24}$ cm$^{-2}$. The electron scattering in the thick absorber might contribute significantly to the observed continuum polarization for both BAL QSOs and non-BAL QSOs. In this paper, we present a detailed study of the electron scattering in the BALR by assuming an equatorial and axisymmetric outflow model. Monte-Carlo simulations are performed to correct the effect of the radiative transfer. Assuming an average covering factor of 0.2 of the BALR, which is consistent with observations, we find the electron scattering in the BALR with a column density of $\sim$ 4 $\times$ 10$^{23}$ cm$^{-2}$ can successfully produce the observed average continuum polarization for both BAL QSOs and non-BAL QSOs. The observed distribution of the continuum polarization of radio quiet quasars (for both BAL QSOs and non-BAL QSOs) is used to constrain the dispersal distribution of the BALR. We find that, to match the observations, the maximum continuum polarization produced by the BALR (while viewed edge-on) peaks at $P$ = 0.34%, which is much smaller than the average continuum polarization of BAL QSOs ($P$ = 0.93%). The discrepancy can be explained by a selection bias that the BAL with larger covering factor, and thus producing larger continuum polarization, is more likely to be detected. A larger sample of radio quiet quasars with accurate measurement of the continuum polarization will give better constraints to the distribution of the BALR properties.

description: Broad Raman-scattered wings of hydrogen lines can be used to map neutral gas illuminated by high-mass stars in star forming regions. Raman scattering transforms far-ultraviolet starlight from the wings of the Lyman beta line (1022 Angstrom to 1029 Angstrom) to red visual light in the wings of the H alpha line (6400 Angstrom to 6700 Angstrom). Analysis of spatially resolved spectra of the Orion Bar and other regions in the Orion Nebula shows that this process occurs in the neutral photo-dissociation region between the ionization front and dissociation front. The inner Raman wings are optically thick and allow the neutral hydrogen density to be determined, implying n(H0) ~= 100,000 per cubic cm for the Orion Bar. Far-ultraviolet resonance lines of neutral oxygen imprint their absorption onto the stellar continuum as it passes through the ionization front, producing characteristic absorption lines at 6633 Angstrom and 6664 Angstrom with widths of order 2 Angstrom. This is a unique signature of Raman scattering, which allows it to be easily distinguished from other processes that might produce broad H alpha wings, such as electron scattering or high-velocity outflows.

description: An experimental precast, post-tensioned concrete segmental girder bridge over Twelvemile Creek in Campbell County was instrumented with stress and strain sensors. Those sensors were read during beam fabrication and the initial portion of construction. The work was performed to address Transportation Cabinet questions about structural performance and also to assess the effect of long-term creep. The study and bridge were not completed as originally designed due a beam failure during post-tensioning.  A variety of stress, strain, and deflection measuring techniques were to be employed during the study. Several of those including concrete stress and strain meters, and vibrating-wire strain gages were embedded in beams and one pier cap. Those sensors were read during several phases of fabrication and construction.  Concrete maturity meters were also employed to determine temperature-time relationships with increases in curing strength for concrete used in the pier caps and in one beam. Compressive strength and modulus tests were also performed on test cylinders obtained from the pier and beam concrete.  This report describes the progress of the field instrumentation and laboratory work to the termination of the study. The study was terminated due to the failure of a beam during erection. The bridge was completed using conventional steel girders.  Based upon the limited study findings and the beam failure, recommendations are provided that the Transportation Cabinet: 1) conduct further research related to the use of maturity meters, and 2) consider employing nondestructive testing of similar beams in fabrication shops.
title: Finite element analysis of hollow structural sections subject to torsion and combined loading
Creators: name: Bartlett, Steven
Publisher: name: Memorial University of Newfoundland

description: The reliability of steel structures is governed by design codes which may vary between countries. These codes may stipulate factors of safety, quality, and loading conditions. The approved steel design codes ensure each structure is designed with the same quality, recommended loading conditions, and safety standards for the design life of the structure. In Canada, steel structures are governed by the Canadian Standards Association (CSA) and designed to CAN/CSA S16-19 – Design of Steel Structures [1]. In the United States, steel structures are governed by the American Institute of Steel Construction (AISC) and designed to ANSI/AISC 360-16 – Specification for Structural Steel Buildings [2]. Both Canada and the United States have similar design principles included in their structural design codes. Therefore, the Canadian steel code and the load-resistant factored design sections of the American steel code are almost interchangeable. From the literature review comparing the most current Canadian and American principle clauses, it was identified ANSI/AISC 360-16 [2] provides mathematical equations for checking HSS in torsion and combined loading while CAN/CSA S16-19 [1] advises the user to complete an elastic analysis for verification. While the approach of completing a finite element analysis to the torsion stress is a very precise method, having the option to use theoretical formulas in accordance with limit state design to analyze this condition could be beneficial to practicing engineers. This thesis concentrates on strength verification of the American torsional clause using non-linear FEA techniques with calculated section capacities to determine if the clause can be a potential recommended method of torsion loading assessment. The objective of this work is to develop a practical method of evaluating hollow structural sections subject to torsion and combined loading in Canada. From the research performed, conclusions are made based on the results of the analysis. Recommendations are provided according to the application of the ANSI/AISC 360-16 [2] torsion clause along with the additional research required for validation as an approved design approach in Canada.

description: All planets and satellites of our solar system are subject to a continuous rain of material, ranging in size from specks of dust to objects the size of boulders. Upon impact, these objects deposit their kinetic energy into the incident surface or atmosphere and affect the environment of the target body in ways not yet well understood. Recent high-profile events - impact flashes on Jupiter and the encounter of comet C/Siding Spring with Mars - brought the study of "extraterrestrial meteors" and their effects into the fore. Here we review the history, status and future prospects of meteor studies on planets other than the Earth. Would bright meteors appear in the atmosphere of Mars and what are the long-term effects on the planet's atmosphere? How do high-speed impacts of particulate matter on the airless surfaces of Mercury and the Moon affect their environment and those of the countless other bodies like them? These are some of the questions we attempt to answer in this Chapter.

description: Understanding the emergence of extreme opinions and in what kind of environment they might become less extreme is a central theme in our modern globalized society. A model combining continuous opinions and observed discrete actions (CODA) capable of addressing the important issue of measuring how extreme opinions might be has been recently proposed. In this paper I show extreme opinions to arise in a ubiquitous manner in the CODA model for a multitude of social network structures. Depending on network details reducing extremism seems to be possible. However, a large number agents with extreme opinions is always observed. A significant decrease in the number of extremists can be observed by allowing agents to change their positions in the network.

description: In this paper, we explore the five-dimensional f(T,B) teleparallel modified gravity with f_1(T,B)=T+k_1B^{n_1} and f_2(T,B)=B+k_2T^{n_2} in the brane scenario. Asymptotically, the bulk geometry converges to an AdS_5 spacetime whose cosmological constant is produced by parameters that control torsion and boundary term. The analysis of the energy density condition reveals a splitting brane process satisfying the weak and strong energy conditions for some values of the parameters n_{1,2} and k_{1,2}. In addition, we investigate the behavior of the gravitational perturbations in this scenario. In the bulk, the torsion keeps a gapless non-localizable, and stable tower of massive modes. Inside the brane core, the torsion produces new barriers and potential wells, leading to small amplitude massive modes and a massless mode localized for some values of the parameters n_{1,2} and k_{1,2}.

In the nonlinear fiber system with third-order dispersion, we illustrate their generation conditions by the modified linear stability analysis, and numerically generate them from initial perturbations on continuous waves. We implement the quantitative control over their dynamical features, including the wave type, velocity, periodicity, and localization. Our results may provide an effective scheme for generating optical solitons on continuous waves, and it can also be applied for wave generations in other various nonlinear systems.

description: It was recently shown that charged AdS boson stars can reproduce the universal structure of the lowest scaling dimension in the subsector of a CFT with fixed large global $U(1)$ charge $Q$. Using the model consisting of Einstein-Maxwell gravity with a negative cosmological constant, coupled to a $U(1)$-charged conformally massless scalar with the fourth-order self interaction, we construct a class of charged AdS boson star solutions in the large $Q$ limit, where the scalar field obeys a mixed boundary condition, parameterized by $k$ that interpolates between the Neumann and Dirichlet boundary conditions corresponding to $k=0$ and $\infty$ respectively. By varying $k$, we numerically read off the $k$ dependence of the leading coefficient $c_{3/2}(k) \equiv \lim_{Q\rightarrow \infty} M/Q^{3/2}$. We find that $c_{3/2}(k)$ is a monotonously increasing function which grows linearly when $k$ is sufficiently small. When $k\rightarrow \infty$, $c_{3/2}(k)$ approaches the maximal value at a decreasing rate given by $k^{-3/2}$ . We also obtain a close form expression that fits the numerical data for the entire range of $k$ within $10^{-4}$ accuracy.

description: The principal objective of the research effort was to develop historical performance data for bituminous sandstone pavements and bituminous limestone pavements relative to visual distress, pavement rutting characteristics, and structural condition using deflection measurements. Data relative to Road Rater deflections, pavement rutting, condition ratings based on subjective visual surveys and objective data such as skid resistance and rideability, were collected and analyzed during the course of the study and reported herein for the routes investigated.  It was concluded, based upon information gained during the evaluation period and presented in this report, that pavements constructed with bituminous sandstone bases do not develop excessive rut depths, are more resistant to shoving and pushing, but appear to exhibit cracking at an earlier age than pavements constructed with bituminous limestone bases. The use of bituminous sandstone mixtures addresses problems such as haul costs, rutting, skid resistance, etc. Field engineers indicated that although bituminous sandstone surface mixtures have a slight tendency to ravel, they are very resistant to rutting and applications of bituminous sandstone base and surface mixtures have been very successful in their estimation.

description: Strong and precisely-controlled interactions between quantum objects are essential for quantum information processing, simulation, and sensing, and for the formation of exotic quantum matter. A well-established paradigm for coupling otherwise weakly-interacting quantum objects is to use auxiliary bosonic quantum excitations to mediate the interactions. Important examples include photon-mediated interactions between atoms, superconducting qubits, and color centers in diamond, and phonon-mediated interactions between trapped ions and between optical and microwave photons. Boson-mediated interactions can in principle be amplified through parametric driving of the boson channel; the drive need not couple directly to the interacting quantum objects. This technique has been proposed for a variety of quantum platforms, but has not to date been realized in the laboratory. Here we experimentally demonstrate the amplification of a boson-mediated interaction between two trapped-ion qubits by parametric modulation of the trapping potential. The amplification provides up to a 3.25-fold increase in the interaction strength, validated by measuring the speedup of two-qubit entangling gates. This amplification technique can be used in any quantum platform where parametric modulation of the boson channel is possible, enabling exploration of new parameter regimes and enhanced quantum information processing.

description: Almost 3500 people are killed and almost 400000 people are injured in the traffic accidents by distracted driving annually in the USA alone. In the EU, 20% of all fatalities on the roads are due to driver distraction (DD). Unfortunately, this trend grows. DD caused by secondary activity detection and minimization is an essential task for vehicle manufacturers. The objective of this study is a development of robust practical tool for DD detection and evaluation methodology. An appropriate hardware and software environment is offered and studied The real-time experiment with 18 volunteers is conducted using the advanced driver-in-the-loop simulator, System Experience Platform, provided by the IPG Automotive GmbH (Karlsruhe, Germany). The drivers completed 2 laps of their normal driving (without a distraction). This performance-based data is exploited to design for each individual driver driving prediction model. Next, the participants drove the simulator respecting all the traffic regulations and simultaneously distracted by the secondary task (i.e. chatting on a cellular phone). The DD detection and evaluation is performed as follows. First, machine learning algorithm, trained with the data collected during free from distraction driving, predicts driver’s non-distracted/normal performance via regression analysis. Second, the predicted driving is compared to the distracted by the interaction with the cellular phone driving performance for DD detection. Finally, the compared data is melted by intelligent fuzzy logic algorithm to merge a single variable, which represents a level of DD in percentage. The main finding is that proposed in this work method allows very precise secondary activity DD detection and following measurement. The suggested methodology can be exploited as a benchmark for safe and clear in-vehicle information system design with minimal driver’s burden from human-machine interface (e.g. voice command and hand gesture recognition). In other related to this studies works [References] for DD detection Boolean 2-class classification is used: distracted/not distracted. These methods are not capable for level of DD measurement and consequent evaluation of secondary tasks’ impact on safe vehicle operation.

description: The South Terminal Visiting Center, aside from its programmatic purpose to educate and entertain, intends to use its form to draw a parallel relationship with the contents of the museum to the tectonics of the aircraft, bridging the gap between architecture for industry and architecture for art. Building Concept- the Hanger Aside from sprawling lawns and concrete runways, aprons and taxis, the aircraft does not belong to any particular physical place except in the air. Hangar, perhaps, is the closest formal typology associated with airplanes. Oftentimes, the word hangar conjures up the notion of an airplane garage or storage. Hangar is often favored as the basic formal unit for industrial purposes because it offers structural efficiency and large volume of open space. The intent is to utilize the hangar-like space that connects to other amenities and facilities in a clear and coherent manner. Siting and Orientation The frontages of the existing neighboring buildings, as well as the direction of the traffic flow determine siting of the Visiting Center. The grid system and the edges of the Visiting Center echo the edges of the Vancouver Jet Center and the Canadian Air Building. The connection of the vehicular routes and the turnout of the Dinsmore Bridge naturally suggest a visual as well as physical connection to South Terminal Airport. Entry of the building would be more relevant to be placed here than at the water's edge. The shape of the site suggests a linear east to west configuration of form.

description: Relations between the local weight distributions of a binary linear code, its extended code, and its even weight subcode are presented. In particular, for a code of which the extended code is transitive invariant and contains only codewords with weight multiples of four, the local weight distribution can be obtained from that of the extended code. Using the relations, the local weight distributions of the $(127,k)$ primitive BCH codes for $k\leq50$, the $(127,64)$ punctured third-order Reed-Muller, and their even weight subcodes are obtained from the local weight distribution of the $(128,k)$ extended primitive BCH codes for $k\leq50$ and the $(128,64)$ third-order Reed-Muller code. We also show an approach to improve an algorithm for computing the local weight distribution proposed before.

description: It is known that the Kauffman-Murasugi-Thislethwaite type inequality becomes an equality for any (possibly virtual) adequate link diagram. We refine this condition. As an application we obtain a criterion for virtual link diagram with exactly one virtual crossing to represent a properly virtual link.

description: With the growing interest in cell-free massive multiple-input multiple-output (MIMO) systems, the benefits of single-antenna access points (APs) versus multi-antenna APs must be analyzed in order to optimize deployment. In this paper, we compare various antenna system topologies based on achievable downlink spectral efficiency, using both measured and synthetic channel data in an indoor environment. We assume multi-user scenarios, analyzing both conjugate beamforming (or maximum-ratio transmission (MRT)) and zero-forcing (ZF) precoding methods. The results show that the semi-distributed multi-antenna APs can reduce the number of APs, and still achieve the comparable achievable rates as the fully-distributed single-antenna APs with the same total number of antennas.

description: We studied a nilpotent Non-Anti-Commutative (NAC) deformation of the effective superpotentials in supersymmetric gauge theories, caused by a constant self-dual graviphoton background. We derived the simple non-perturbative formula applicable to any NAC (star) deformed chiral superpotential. It is remarkable that the deformed superpotential is always `Lorentz'-invariant. As an application, we considered the NAC deformation of the pure super-Yang-Mills theory whose IR physics is known to be described by the Veneziano-Yankielowicz superpotential (in the undeformed case). The unbroken gauge invariance of the deformed effective action gives rise to severe restrictions on its form. We found a non-vanishing gluino condensate in vacuum but no further dynamical supersymmetry breaking in the deformed theory.

description: Rotating massive stars at $Z=10^{-8}$ and $10^{-5}$ lose a great part of their initial mass through stellar winds. The chemical composition of the rotationally enhanced winds of very low $Z$ stars is very peculiar. The winds show large CNO enhancements by factors of $10^3$ to $10^7$, together with large excesses of $^{13}$C and $^{17}$O and moderate amounts of Na and Al. The excesses of primary N are particularly striking. When these ejecta from the rotationally enhanced winds are diluted with the supernova ejecta from the corresponding CO cores, we find [C/Fe], [N/Fe],[O/Fe] abundance ratios very similar to those observed in the C--rich extremely metal poor stars (CEMP). We show that rotating AGB stars and rotating massive stars have about the same effects on the CNO enhancements. Abundances of s-process elements and the $^{12}$C/$^{13}$C ratio could help us to distinguish between contributions from AGB and massive stars. On the whole, we emphasize the dominant effects of rotation for the chemical yields of extremely metal poor stars.

description: High-entropy perovskite thin films, as the prototypical representative of the high-entropy oxides with novel electrical and magnetic features, have recently attracted great attention. Here, we reported the electronic structure and charge transport properties of sol-gel-derived high-entropy Ba(Zr0.2Sn0.2Ti0.2Hf0.2Nb0.2)O3 thin films annealed at various temperatures. By means of X-ray photoelectron spectroscopy and absorption spectrum, it is found that the conduction-band-minimum shifts downward and the valence-band-maximum shifts upward with the increase of annealing temperature, leading to the narrowed band gap. Electrical resistance measurements confirmed a semiconductor-like behavior for all the thin films. Two charge transport mechanisms, i.e., the thermally-activated transport mechanism at high temperatures and the activation-less transport mechanism at low temperatures, are identified by a self-consistent analysis method. These findings provide a critical insight into the electronic band structure and charge transport behavior of Ba(Zr0.2Sn0.2Ti0.2Hf0.2Nb0.2)O3, validating it as a compelling high-entropy oxide material for future electronic/energy-related technologies.
