description: The theory of multidimensional persistence captures the topology of a multifiltration - a multiparameter family of increasing spaces. Multifiltrations arise naturally in the topological analysis of scientific data. In this paper, we give a polynomial time algorithm for computing multidimensional persistence. We recast this computation as a problem within computational commutative algebra and utilize algorithms from this area to solve it. While the resulting problem is EXPSPACE-complete and the standard algorithms take doubly-exponential time, we exploit the structure inherent withing multifiltrations to yield practical algorithms. We implement all algorithms in the paper and provide statistical experiments to demonstrate their feasibility.

description: We study the complexity of the visibility map of terrains whose triangles are fat, not too steep and have roughly the same size. It is known that the complexity of the visibility map of such a terrain with n triangles is Θ(n2) in the worst case. We prove that if the elevations of the vertices of the terrain are subject to uniform noise which is proportional to the edge lengths, then the worst-case expected (smoothed) complexity is only Θ(n). We also prove non-trivial bounds for the smoothed complexity of instances where some triangles do not satisfy the above properties. Our results provide an explanation why visibility maps of superlinear complexity are unlikely to be encountered in practice.

description: The Strategic Highway Investment Formula for Tomorrow (SHIFT) program research team evaluated the program’s 2018 safety component and developed a new methodology to rank the safety needs of 2020 projects. For the current year, the research team suggests replacing the SHIFT 2018 formulas (based on three naive crash measures) with a new metric, Excess Expected Crashes, formulated from the most current safety analysis guidelines available in the Highway Safety Manual. In addition, the research team developed a user-friendly network screening tool serving as a method to prioritize projects. Another automation tool was developed that will help safety professionals evaluate and prioritize projects in an efficient manner, replacing the laborious manual calculation needed for each project. This report details the new methodology and tools.

description: Femoroacetabular impingement syndrome (FAIS) is an abnormal physical hip morphology that causes functional changes and pain during gait. Mechanical gait differences in this population require further biomechanical investigation to elucidate characteristics unique to this group. Fixed speed gait trials were performed on force plates and analyzed in addition to isokinetic strength testing to find a multitude of biomechanical variables including joint moment, joint power, joint work, and peak joint angle. This work has discovered evidence of muscular deficits at the hip, specifically hip extension, as well as knee joint power contributions to gait when compared to controls. These findings suggest the FAIS population may be compensating at the knee for hip musculature deficits or disfunction. Additionally, verbal cueing may be implemented to correct altered gait patterns and assist in pain reduction during gait. When given a targeted verbal cue to promote trunk extension, the FAIS alters their ambulation entirely kinematically and maintains the kinetic profile of their standard gait. The control group, when given the cue, altered their knee joint kinematics which suggests that further research on gait retraining with cues must be designed to ensure kinetic changes occur in the intervention group when desired.

description: Motivated by breakthroughs in the synthesis of faceted nano- and colloidal particles, as well as theoretical and computational studies of their packings, we investigate a family of truncated triangular bipyramids. We report dense periodic packings with small unit cells that were obtained via numerical and analytical optimization. The maximal packing fraction $ϕ_{\max}$ changes continuously with the truncation parameter $t$. Eight distinct packings are identified based on discontinuities in the first and second derivatives of $ϕ_{\max}(t)$. These packings differ in the number of particles in the fundamental domain (unit cell) and the type of contacts between the particles. In particular, we report two packings with four particles in the unit cell for which both $ϕ_{\max}(t)$ and $ϕ'_{\max}(t)$ are continuous and the discontinuity occurs in the second derivative only. In the self-assembly simulations that we perform for larger boxes with 2048 particles, only one out of eight packings is found to assemble. In addition, the degenerate quasicrystal reported previously for triangular bipyramids without truncation [{http://prl.aps.org/abstract/PRL/v107/i21/e215702}{Haji-Akbari \emph{et al.}, \emph{Phys. Rev. Lett.} \textbf{107}: 215702 (2011)}] assembles for truncations as high as 0.45. The self-assembly propensities for the structures formed in the thermodynamic limit are explained using the isoperimetric quotient of the particles and the coordination number in the disordered fluid and in the assembled structure.

description: We study the implications at the LHC for the minimal (least) version of the supersymmetric standard model. In this model supersymmetry is broken by gravity and extra gauge interactions effects, providing a spectrum similar in several aspects to that in natural supersymmetric scenarios. Having the first two generations of sparticles partially decoupled means that any significant signal can only involve gauginos and the third family of sfermions. In practice, the signals are dominated by gluino production with subsequent decays into the stop sector. As we show, for gluino masses below 2300 GeV, a discovery at the LHC is possible at \sqrt{s}=14 TeV, but will require large integrated luminosities.

description: We analyze efficiency of excitation energy transfer in photosynthetic complexes in transient and stationary setting. In the transient setting the absorption process is modeled as an individual event resulting in a subsequent relaxation dynamics. In the stationary setting the absorption is a continuous stationary process, leading to the nonequilibrium steady state. We show that, as far as the efficiency is concerned, both settings can be considered to be the same, as they result in almost identical efficiency. We also show that non-Markovianity has no effect on the resulting efficiency, i.e., corresponding Markovian dynamics results in identical efficiency. Even more, if one maps dynamics to appropriate classical rate equations, the same efficiency as in quantum case is obtained.

More Clarification, Less Item Nonresponse in Establishment Surveys? A Split-Ballot Experiment

Year: 2021

description: The IAB Job Vacancy Survey of the German Institute for Employment Research collects detailed information on job search and vacancy durations for an establishment’s last successful hiring process. The duration questions themselves are burdensome for respondents to answer as they ask for precise dates of the earliest possible hiring for the vacancy, the start of the personnel search, and the decision to hire the selected applicant. Consequently, the nonresponse rates for these items have been relatively high over the years (up to 21 percent). In an effort to reduce item nonresponse, a split-ballot experiment was conducted to test the strategy of providing additional clarifying information and examples to assist respondents in answering the date questions. The results revealed a backfiring effect. Although there was evidence that respondents read the additional clarifying information, this led to even more item nonresponse and lower data quality compared to the control group. Additionally, we observed a negative spillover effect with regard to item nonresponse on a subsequent (non-treated) question. We conclude this article by discussing possible causes of these results and suggestions for further research.

description: Survey duration—the time it takes to complete a survey—affects response and completion rates. Estimated survey duration equations may be used to estimate survey duration, however, there are no studies assessing their use. The objective of this study is to evaluate estimated survey duration equations using a health risk assessment. Six existing estimated survey duration equations were identified. Using health risk assessment data from January 1, 2018 to December 31, 2018, an average participant profile was built to inform the inputs into the estimated survey duration equations. Estimated survey duration of the health risk assessment ranged from 7.64 minutes to 39.6 minutes. Using the same dataset, the estimated survey duration was compared to the actual completion time of the health risk assessment. The average completion time of the health risk assessment was 11.27 minutes. The estimated survey duration equations either under- or overestimated the completion time of the health risk assessment. The equation that is based on word count, number of questions, decisions, and open text boxes is recommended for use to estimate the duration of a health risk assessment although it was an overestimate. Using estimated survey duration equations appear to be a suitable alternative to pilot testing but future studies are needed to further evaluate these equations in other types of surveys.

Directional Pattern based Clustering for Quantitative Survey Data: Method and Application
Creators: name: Sadh, Roopam

Year: 2021

description: Analysis of survey data is a matter of significant concern as it plays a key role in organizational and behavioral research. Quantitative survey data possesses several distinct characteristics i.e., fixed small range of ordinal values, importance of respondent category labels etc. Due to such reasons quantitative survey data is not appropriate for existing analysis methods involving aggregate statistics. Literature has advised to utilize pattern based analysis tools instead of aggregate statistics since patterns are more informative and efficient in reflecting respondents’ preferences. Thus, we introduce a specialized pattern based clustering technique for survey data that uses the convention of direction instead of magnitude. Further, it does not require manual setting of clustering parameters whereas it automatically identifies respondent categories and their representative features with the help of an adaptive procedure. We apply proposed method over an original academic survey dataset and compare its results with K-Means clustering method in terms of interpretability and usability. We utilize benchmark stakeholder theory to verify the results. Results suggest that proposed pattern clustering method performs far better in segregating survey responses according to the stakeholder theory and the clusters made by it are much more meaningful. Hence, results empirically validates that pattern based analysis methods are more suitable for analyzing quantitative survey data.

description: We investigate the consequences of adopting the criteria used by the state of California, as described by Myers et al. (2011), for conducting familial searches. We carried out a simulation study of randomly generated profiles of related and unrelated individuals with 13-locus CODIS genotypes and YFiler Y-chromosome haplotypes, on which the Myers protocol for relative identification was carried out. For Y-chromosome sharing first degree relatives, the Myers protocol has a high probability (80 - 99%) of identifying their relationship. For unrelated individuals, there is a low probability that an unrelated person in the database will be identified as a first-degree relative. For more distant Y-haplotype sharing relatives (half-siblings, first cousins, half-first cousins or second cousins) there is a substantial probability that the more distant relative will be incorrectly identified as a first-degree relative. For example, there is a 3 - 18% probability that a first cousin will be identified as a full sibling, with the probability depending on the population background. Although the California familial search policy is likely to identify a first degree relative if his profile is in the database, and it poses little risk of falsely identifying an unrelated individual in a database as a first-degree relative, there is a substantial risk of falsely identifying a more distant Y-haplotype sharing relative in the database as a first-degree relative, with the consequence that their immediate family may become the target for further investigation. This risk falls disproportionately on those ethnic groups that are currently overrepresented in state and federal databases.

Dependent interviewing: a remedy or a curse for measurement error in surveys?
Creators: name: Pankowska, Paulina

description: Longitudinal surveys often rely on dependent interviewing (DI) to lower the levels of random measurement error in survey data and reduce the incidence of spurious change. DI refers to a data collection technique that incorporates information from prior interview rounds into subsequent waves. While this method is considered an eective remedy for random measurement error, it can also introduce more systematic errors, in particular when respondents are rst reminded of their previously provided answer and then asked about their current status. The aim of this paper is to assess the impact of DI on measurement error in employment mobility. We take advantage of a unique experimental situation that was created by the roll-out of dependent interviewing in the Dutch Labour Force Survey (LFS). We apply Hidden Markov Modeling (HMM) to linked LFS and Employment Register (ER) data that cover a period before and after dependent interviewing was abolished, which in turn enables the modeling of systematic errors in the LFS data. Our results indicate that DI lowered the probability of obtaining random measurement error but had no signicant eect on the systematic component of the error. The lack of a signicant eect might be partially due to the fact that the probability of repeating the same error was extremely high at baseline (i.e when using standard, independent interviewing); therefore the use of DI could not increase this probability any further.

Establishing a baseline: bringing innovation to the evaluation of cross-national probability-based online panels
Creators: name: Bottoni, Gianmaria

Publisher: name: Survey Research Methods
Year: 2021

description: A number of countries in Europe and beyond have established online or mixed mode panels with a web component based upon probability samples. This paper aims to assess the first ever attempt to do this cross-nationally using an input harmonised approach representing a major innovation in cross-national survey methodology. The European Social Survey established a panel using the face-to-face interview as the basis for recruitment to the panel. This experiment was conducted in Estonia, Slovenia and Great Britain using an input harmonised approach to the design throughout something never done before across multiple countries simultaneously. The paper outlines how the experiment was conducted. It then moves on to compare the web panel respondents to the ESS achieved face-to-face sample in each country, as well as comparing the web panel achieved sample to external benchmarks. Most importantly, since the literature is very scarce, the differences in attitudinal and behavioural characteristics are also assessed. By comparing the answers of the total achieved sample in the ESS to the subset who also answered the CRONOS web panel we assess changes in representativeness and substantive answers without confounding the findings with other changes such as mode effects. This approach is only possible where ‘piggybacking’ recruitment has been used. This in itself is rare at the national level but this is the first time survey methodologists have employed this cross-nationally allowing such an analytical approach. Our findings suggest that the CRONOS sample is not too divergent from the target population and to the ESS with the exception of the oldest age groups. However, there are cross-national differences suggesting cross-national comparability might be different when compared to estimates from a face-to-face survey.

description: A near-hollow plasma channel, where the plasma density in the channel is much less than the plasma density in the walls, is proposed to provide independent control over the focusing and accelerating forces in a plasma accelerator. In this geometry the low density in the channel contributes to the focusing forces, while the accelerating fields are determined by the high density in the channel walls. The channel also provides guiding for intense laser pulses used for wakefield excitation. In certain regimes, both electron and positron beams can be accelerated and focused in a nearly symmetric fashion. Near-hollow plasma channels can effectively mitigate emittance growth due to Coulomb scattering for high-energy physics applications.

description: In the article we describe an enhancement to the Demand for Labour (DL) survey con- ducted by Statistics Poland, which involves the inclusion of skills obtained from online job advertisements. The main goal is to provide estimates of the demand for skills (competences), which is missing in the DL survey. To achieve this, we apply a data integration approach com- bining traditional calibration with the LASSO-assisted approach to correct coverage and selec- tion error in the online data. Faced with the lack of access to unit-level data from the DL survey, we use estimated population totals and propose a bootstrap approach that accounts for the un- certainty of totals reported by Statistics Poland. We show that the calibration estimator assisted with LASSO outperforms traditional calibration in terms of standard errors and reduces rep- resentation bias in skills observed in online job ads. Our empirical results show that online data significantly overestimate interpersonal, managerial and self-organization skills while un- derestimating technical and physical skills. This is mainly due to the under-representation of occupations categorised as Craft and Related Trades Workers and Plant and Machine Operators and Assemblers.

description: Noether's theory offers us a useful tool to research the conserved quantities and symmetries of the modified gravity theories, among which the $f(T)$ theory, a generally modified teleparallel gravity, has been proposed to account for the dark energy phenomena. By the Noether symmetry approach, we investigate the power-law, exponential and polynomial forms of $f(T)$ theories. All forms of $f(T)$ concerned in this work possess the time translational symmetry, which is related with energy condition or Hamilton constraint. In addition, we find out that the performances of the power-law and exponential forms are not pleasing. It is rational adding a linear term $T$ to $T^n$ as the most efficient amendment to resemble the teleparallel gravity or General Relativity on small scales, ie., the scale of the solar system. The corresponding Noether symmetry indicates that only time translational symmetry remains. Through numerically calculations and observational data-sets constraining, the optimal form $αT + βT^{-1}$ is obtained, whose cosmological solution resembles the standard $Λ$CDM best with lightly reduced cosmic age which can be alleviated by introducing another $T^m$ term. More important is that we find the significant differences between $Λ$CDM and $f(T)$ gravity. The $Λ$CDM model has also two additional symmetries and corresponding positive conserved quantities, except the two negative conserved quantities.

description: We make a critical study of two highly-constrained models of supersymmetry --- the constrained minimal supersymmetric standard model (cMSSM), and the non-universal Higgs mass model (NUHM) --- in the light of the 125-126 GeV Higgs boson, the first observation of $B_s \to μμ$ at the LHCb, and the updated $B \to τν$ branching ratio at BELLE. It turns out that these models are still allowed by the experimental data, even if we demand that there be a light stop with mass less than 1.5 TeV. The only significant effects of all these constraints are to push the mass of the light stop above $\sim 500$ GeV, and to prefer the universal trilinear coupling $A_0$ to be large and negative. We calculate the Higgs boson branching ratios to $WW, ZZ, ττ$ and $γγ$ in these models and show that improved experimental limits on these could put them to the most stringent experimental tests yet.

description: To investigate the effect of energy and helicity on the growth of magnetic field, helical kinetic forcing was applied to the magnetohydrodynamic(MHD) system that had a specific distribution of energy and helicity as initial conditions. Simulation results show the saturation of a system is not influenced by the initial conditions, but the growth rate of large scale magnetic field is proportionally dependent on the initial large scale magnetic energy and helicity. It is already known that the helical component of small scale magnetic field(i.e., current helicity $$) quenches the growth of large scale magnetic field. However, $$ can also boost the growth of large scale magnetic field by changing its sign and magnitude. In addition, simulation shows the nonhelical magnetic field can suppress the velocity field through Lorentz force. Comparison of the profiles of evolving magnetic and kinetic energy indicates that kinetic energy migrates backward when the external energy flows into the three dimensional MHD system, which means the velocity field may play a preceding role in the very early MHD dynamo stage.

description: Sky masking is unavoidable in wide-field weak lensing observations. We study how masks affect the measurement of statistics of matter distribution probed by weak gravitational lensing. We first use 1000 cosmological ray-tracing simulations to examine in detail the impact of masked regions on the weak lensing Minkowski Functionals (MFs). We consider actual sky masks used for a Subaru Suprime-Cam imaging survey. The masks increase the variance of the convergence field and the expected values of the MFs are biased. The bias then affects the non-Gaussian signals induced by the gravitational growth of structure. We then explore how masks affect cosmological parameter estimation. We calculate the cumulative signal-to-noise ratio S/N for masked maps to study the information content of lensing MFs. We show that the degradation of S/N for masked maps is mainly determined by the effective survey area. We also perform simple chi^2 analysis to show the impact of lensing MF bias due to masked regions. Finally, we compare ray-tracing simulations with data from a Subaru 2 deg^2 survey in order to address if the observed lensing MFs are consistent with those of the standard cosmology. The resulting chi^2/n_dof = 29.6/30 for three combined MFs, obtained with the mask effects taken into account, suggests that the observational data are indeed consistent with the standard LambdaCDM model. We conclude that the lensing MFs are powerful probe of cosmology only if mask effects are correctly taken into account.

description: We perform numerical tests on quantum nonlocality of two-level quantum systems (qubits) observed by a uniformly moving observer. Under a suitable momentum setting, the quantum nonlocality of two-qubit nonmaximally entangled states could be weakened drastically by the Lorentz transformation allowing for the existence of local-hidden-variable models, whereas three-qubit genuinely entangled states are robust. In particular, the generalized GHZ state remains nonlocal under arbitrary Wigner rotation and the generalized W state could admit local-hidden-variable models within a rather narrow range of parameters.

description: Evans (2007) defines insubordination as the conventionalised main clause use of what appear to be formally subordinate clauses. D’Hertefelt (2018) constructed an insubordination typology for six Germanic languages for both complement insubordinate constructions starting with that (and its equivalents in the other languages) as well as conditional insubordinate constructions starting with if. In this paper, we aim to extend both typologies to include Afrikaans using a corpus investigation and show that Afrikaans is very similar to Dutch with respect to the types of insubordinate constructions that occur, and that together with Dutch, it has the largest number of different types for the investigated constructions. We also investigate the use of insubordination of other subordinators in Afrikaans, both for complement constructions and for some causal and temporal constructions.

description: We consider the theory of the glass phase and jamming of hard spheres in the large space dimension limit. Building upon the exact expression for the free-energy functional obtained previously, we find that the Random First Order Transition (RFOT) scenario is realized here with two thermodynamic transitions: the usual Kauzmann point associated with entropy crisis, and a further transition at higher pressures in which a glassy structure of micro-states is developed within each amorphous state. This kind of glass-glass transition into a phase dominating the higher densities was described years ago by Elisabeth Gardner, and may well be a generic feature of RFOT. Micro states that are small excitations of an amorphous matrix -- separated by low entropic or energetic barriers -- thus emerge naturally, and modify the high pressure (or low temperature) limit of the thermodynamic functions.

Momentum and Heat Transfer Studies. I. Transfer of Heat and Momentum in Uniform Turbulent Air Streams. II. Continuous Velocity Measurements by the Hot Wire Method
Creators: name: Sherwin, Robert Mitchell
Publisher: name: California Institute of Technology
Year: 1952
Subjects: subject: Chemical Engineering
subject: FOS: Chemical engineering

description: Part I

The thermal flux has been measured across an air stream flowing
in a uniform, two-dimensional manner between horizontal parallel
plates at different temperatures. Reynolds numbers ranged from 9,800
to 56,500. A macroscopic correlation shows the effect of turbulence
on the thermal transfer.

A revised correlation of total conductivity as a function
of position is subsequently obtained by correcting previously deter­mined
values of total conductivity. A similar correlation of the
total viscosity with position is revised to allow for variation in
the pressure gradient with plate separation. The correlations fall
off with increasing Reynolds number. The turbulent Prandtl numbers
for two tests by an earlier investigator are compared with those predicted
from the ratio of the revised point correlations.

Part II

Two hot-wire methods are described for determining continuously
the mean velocity as a function of position in a turbulently-flowing
air stream. In the constant-resistance method the mean wire temperature
is automatically controlled. In the constant-current method no
control is necessary. In exploratory measurements the total
viscosities bridge the discontinuous gap which arises from the use of
von Kármán's expression at the boundary between the buffer layer and
the turbulent core. Thermal flux corresponding to a Nusselt number
of 40 has no noticeable effect on the velocity profile.
Triboelectric charging of volcanic ash from the 2011 Grímsvötn eruption

description: The plume from the 2011 eruption of Grímsvötn was highly electrically charged, as shown by the considerable lightning activity measured by the UK Met Office's low-frequency lightning detection network. Previous measurements of volcanic plumes have shown that ash particles are electrically charged up to hundreds of km away from the vent, which indicates that the ash continues to charge in the plume [Harrison et al., Env. Res. Lett. 5 024004 (2010), Hatakeyama J. Met. Soc. Japan 27 372 (1949)]. In this paper we study triboelectric charging of different size fractions of a sample of volcanic ash experimentally. Consistently with previous work, we find that the particle size distribution is a determining factor in the charging. Specifically, our laboratory experiments demonstrate that the normalised span of the particle size distribution plays an important role in the magnitude of charging generated. The influence of the normalised span on plume charging suggests that all ash plumes are likely to be charged, with implications for remote sensing and plume lifetime through scavenging effects.

description: We provide a systematic classification of multiparticle entanglement in terms of equivalence classes of states under stochastic local operations and classical communication (SLOCC). We show that such an SLOCC equivalency class of states is characterized by ratios of homogenous polynomials that are invariant under local action of the special linear group. We then construct the complete set of all such SL-invariant polynomials (SLIPs). Our construction is based on Schur-Weyl duality and applies to any number of qudits in all (finite) dimensions. In addition, we provide an elegant formula for the dimension of the homogenous SLIPs space of a fixed degree as a function of the number of qudits. The expressions for the SLIPs involve in general many terms, but for the case of qubits we also provide much simpler expressions.

The hidden symmetry-breaking picture of symmetry-protected topological order

description: We generalize the hidden symmetry-breaking picture of symmetry-protected topological (SPT) order developed by Kennedy and Tasaki in the context of the Haldane phase. Our generalization applies to a wide class of SPT phases in one-dimensional spin chains, protected by an on-site representation of a finite abelian group. This generalization takes the form of a non-local unitary map that relates local symmetry-respecting Hamiltonians in an SPT phase to local Hamiltonians in a symmetry-broken phase. Using this unitary, we establish a relation between the two-point correlation functions that characterize fully symmetry-broken phases with the string-order correlation functions that characterise the SPT phases, therefore establishing the perspective in these systems that SPT phases are characterised by hidden symmetry-breaking. Our generalization is also applied to systems with continuous symmetries, including SO(2k+1) and SU(k).
