description: In this paper, we find a necessary and sufficient condition for multi-twisted Reed-Solomon codes to be MDS. In particular, we introduce a new class of MDS double-twisted Reed-Solomon codes $\mathcal{C}_{\bm α, \bm t, \bm h, \bm η}$ with twists $\bm t = (1, 2)$ and hooks $\bm h = (0, 1)$ over the finite field $\mathbb{F}_q$, providing a non-trivial example over $\mathbb{F}_{16}$ and enumeration over the finite fields of size up to 17. Moreover, we obtain necessary conditions for the existence of multi-twisted Reed-Solomon codes with small dimensional hull. Consequently, we derive conditions for the existence of MDS multi-twisted Reed-Solomon codes with small dimensional hull.

description: In a noisy environment, oscillations loose their coherence which can be characterized by a quality factor. We determine this quality factor for oscillations arising from a driven Fokker-Planck dynamics along a periodic one-dimensional potential analytically in the weak noise limit. With this expression, we can prove for this continuum model the analog of an upper bound that has been conjectured for the coherence of oscillations in discrete Markov network models. We show that our approach can also be adapted to motion along a noisy two-dimensional limit cycle. Specifically, we apply our scheme to the noisy Stuart-Landau oscillator and the thermodynamically consistent Brusselator as a simple model for a chemical clock. Our approach thus complements the fairly sophisticated extant general framework based on techniques from Hamilton-Jacobi theory with which we compare our results numerically.

description: Recently multiscale imaging approaches such as DoG-HiT were developed to solve the VLBI imaging problem and showed a promising performance: they are fast, accurate, unbiased and automatic. We extend the multiscalar imaging approach to polarimetric imaging, reconstructions of dynamically evolving sources and finally to dynamic polarimetric reconstructions. These extensions (mr-support imaging) utilize a multiscalar approach. The time-averaged Stokes I image is decomposed by a wavelet transform into single subbands. We use the set of statistically significant wavelet coefficients, the multiresolution support, computed by DoG-HiT as a prior in a constrained minimization manner: we fit the single-frame (polarimetric) observables by only varying the coefficients in the multiresolution support. The EHT is a VLBI array imaging supermassive black holes. We demonstrate on synthetic data that mr-support imaging offers ample regularization and is able to recover simple geometric dynamics at the horizon scale in a typical EHT setup. The approach is relatively lightweight, fast and largely automatic and data driven. The ngEHT is a planned extension of the EHT designed to recover movies at the event horizon scales of a supermassive black hole. We benchmark the performance of mr-support imaging for the denser ngEHT configuration demonstrating the major improvements the additional ngEHT antennas will bring to dynamic, polarimetric reconstructions. Current and upcoming instruments offer the observational possibility to do polarimetric imaging of dynamically evolving structural patterns with highest spatial and temporal resolution. State-of-the-art dynamic reconstruction methods can capture this motion with a range of temporal regularizers and priors. With this work, we add an additional, simpler regularizer to the list: constraining the reconstruction to the multiresolution support.

title: Evaluation of the Filter Paper Method for Estimating Soil Water Potential
Creators: name: Al-Khafaf, Samir
Publisher: name: Utah State University
Year: 1972

description: The filter paper method for measuring soil water potential was evaluated. The method was calibrated using salt solutions (-1.4 bars to -22.4 bars), sample chamber psychrometer (-1 to -50 bars), pressure plate (-0.1 to - 15 bars) and soil column at equilibrium (0 to -0.2 bars). It was found that the absolute temperature had little effect on the predicted soil water potential, but a temperature variation had a large effect. It was found that the temperature fluctuation must be small. The predicted water potential was influenced by the type of contact of the soil with the filter paper. It is suggested that one filter paper be placed beneath the soil (good contact for liquid or vapour flow) and one filter paper be placed above the soil not in physical contact (allowing vapour flow only).
The equilibrium between the filter paper and soil mass was essential completed by the end of two days and certainly by the end of five days.

description: This Tech Brief summarizes an Intelligent Transportation System (ITS) study titled Evaluation of Techniques for Ocular Measurement as an Index of Fatigue and as the Basis for Alertness Management. The study was funded in part by FHWA’s Office of Motor Carriers and managed by the National Highway Traffic Safety Administration (NHTSA). The project’s goal was to evaluate the validity and reliability of several drowsiness-detection measures and technologies in a controlled laboratory setting, and to analyze the effects of alerting stimuli on drivers’ alertness levels. Of the drowsiness-detection measures and technologies evaluated in this study, the measure referred to as “PERCLOS” was found to be the most reliable and valid determination of a driver’s alertness level. PERCLOS is the percentage of eyelid closure over the pupil over time and reflects slow eyelid closures (“droops”) rather than blinks. A PERCLOS drowsiness metric was established in a 1994 driving simulator study as the proportion of time in a minute that the eyes are at least 80 percent closed. (Wierwille et al., 1994) Based on research by Wierwille and colleagues (1994), FWHA and NHTSA consider PERCLOS to be among the most promising known real-time measures of alertness for in-vehicle drowsiness-detection systems. The results of this research support the development of a “first-ever” real-time drowsiness detection sensor that would measure the percentage of eyelid closure over the pupil, over time (i.e., PERCLOS)

description: We study numerically the effects of loop quantum gravity motivated corrections on massless scalar field collapse in Painlevé-Gullstrand coordinates. Near criticality, the system exhibits Choptuik scaling with the added features of a mass gap and a new scaling relationship dependant upon the quantum length scale. The quantum corrected collapse exhibits a radiation-like phase which resolves the singularity: the black hole consists of a compact region of space-time bounded by a single, smooth trapping horizon. The "evaporation" is not complete but leaves behind an outward moving remnant.

title: The Overwintering of the Fireblight Bacteria Outside of Living Tissue in Utah
Creators: name: Thomson, Sherman
Publisher: name: Utah State University
Year: 1969

description: The purpose of this investigation was to determine the sites of overwintering of Erwinia amylovora (Burrill) Winslow et al . outside of living tissue in Utah. Bacterial isolates were taken from the surfaces of blighted twigs and mummified fruits remaining on the tree; also from internal dead tissue of blighted twigs and mummies, and from soil beneath blighted trees. Each isolate was tested for agglutination with antiserum specific for Erwina amylovora, susceptibility to Erwinia amylovora bacteriophage, production of symptoms in pear seedlings and development of bacterial ooze on green pears.
Both virulent and avirulent isolates were taken from all sites tested. There was also a slight increase in the number of Erwinia amylovora isolates taken as spring approached . There was no apparent difference in apple or pear trees as overwintering hosts.

description: This is the second one of a series of four papers devoted to a first calculation of the scalar and spinor QED four-photon amplitudes completely off-shell. We use the worldline formalism which provides a gauge-invariant decomposition for these amplitudes as well as compact integral representations. It also makes it straightforward to integrate out any given photon leg in the low-energy limit, and in the present sequel we do this with two of the four photons. For the special case where the two unrestricted photon momenta are equal and opposite the information on these amplitudes is also contained in the constant-field vacuum polarisation tensors, which provides a check on our results. Although these amplitudes are finite, for possible use as higher-loop building blocks we evaluate all integrals in dimensional regularisation. As an example, we use them to construct the two-loop vacuum polarisation tensors in the low-energy approximation, rederive from those the two-loop $β$-function coefficients and analyse their anatomy with respect to the gauge-invariant decomposition. As an application to an external-field problem, we provide a streamlined calculation of the Delbrück scattering amplitudes in the low-energy limit. All calculations are done in parallel for scalar and spinor QED.

description: We give a finite-sample analysis of predictive inference procedures after model selection in regression with random design. The analysis is focused on a statistically challenging scenario where the number of potentially important explanatory variables can be infinite, where no regularity conditions are imposed on unknown parameters, where the number of explanatory variables in a "good" model can be of the same order as sample size and where the number of candidate models can be of larger order than sample size. The performance of inference procedures is evaluated conditional on the training sample. Under weak conditions on only the number of candidate models and on their complexity, and uniformly over all data-generating processes under consideration, we show that a certain prediction interval is approximately valid and short with high probability in finite samples, in the sense that its actual coverage probability is close to the nominal one and in the sense that its length is close to the length of an infeasible interval that is constructed by actually knowing the "best" candidate model. Similar results are shown to hold for predictive inference procedures other than prediction intervals like, for example, tests of whether a future response will lie above or below a given threshold.

description: We have performed particle-resolved direct numerical simulations of many heavy non-spherical particles settling under gravity in the dilute regime. The particles are oblate spheroids of aspect ratio 1.5 and density ratio 1.5. Two Galileo numbers are considered, namely 111 and 152, for which a single oblate spheroid follows a steady vertical and a steady oblique path, respectively. In both cases, a strongly inhomogeneous spatial distribution of the disperse phase in the form of columnar clusters is observed, with a significantly enhanced average settling velocity as a consequence. Thus, in contrast to previous results for spheres, the qualitative difference in the single particle regime does not result in a qualitatively different behavior of the many-particle cases. In addition, we have carried out an analysis of pairwise interactions of particles in the well-known drafting-kissing-tumbling setup, for oblate spheroids of aspect ratio 1.5 and for spheres. We have varied systematically the relative initial position between the particle pair and we have considered free-to-rotate particles and rotationally-locked ones. We have found that the region of attraction for both particle shapes, with and without rotation, is very similar. However, significant differences occur during the drafting and tumbling phases. In particular, free-to-rotate spheres present longer drafting phases and separate quickly after the collision. Spheroids remain close to each other for longer times after the collision, and free-to-rotate ones experience two or more collision events. Therefore, we have observed a shape-induced increase in the interaction which might explain the increased tendency to cluster of the many-particle cases.

description: We report the detection of the lowest energy conformer of $E$-1-cyano-1,3-butadiene ($E$-1-C$_4$H$_5$CN), a linear isomer of pyridine, using the fourth data reduction of the GOTHAM deep spectral survey toward TMC-1 with the 100 m Green Bank Telescope. We performed velocity stacking and matched filter analyses using Markov chain Monte Carlo simulations and find evidence for the presence of this molecule at the 5.1$σ$ level. We derive a total column density of $3.8^{+1.0}_{-0.9}\times 10^{10}$ cm$^{-2}$, which is predominantly found toward two of the four velocity components we observe toward TMC-1. We use this molecule as a proxy for constraining the gas-phase abundance of the apolar hydrocarbon 1,3-butadiene. Based on the three-phase astrochemical modeling code NAUTILUS and an expanded chemical network, our model underestimates the abundance of cyano-1,3-butadiene by a factor of 19, with a peak column density of $2.34 \times 10^{10}\ \mathrm{cm}^{-2}$ for 1,3-butadiene. Compared to the modeling results obtained in previous GOTHAM analyses, the abundance of 1,3-butadiene is increased by about two orders of magnitude. Despite this increase, the modeled abundances of aromatic species do not appear to change and remain underestimated by 1--4 orders of magnitude. Meanwhile, the abundances of the five-membered ring molecules increase proportionally with 1,3-butadiene by two orders of magnitudes. We discuss implications for bottom-up formation routes to aromatic and polycyclic aromatic molecules.
Non-Abelian Landau-Ginzburg Theory of Ferromagnetic Superconductivity and Photon-Spinon Mixing

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: We propose an effective theory of non-Abelian superconductivity, an SU(2)xU(1) extension of the Abelian Landau-Ginzburg theory, which could be viewed as an effective theory of ferromagnetic superconductivity made of spin-up and spin-down doublet Cooper pair. Just like the Abelian Landau-Ginzburg theory it has the U(1) electromagnetic interaction, but the new ingredient is the non-Abelian SU(2) gauge interaction between the spin doublet Cooper pair. A remarkable feature of the theory is the mixing between the photon and the diagonal part of the SU(2) gauge boson. After the mixing it has massless gauge boson (the massless non-Abelian spinon) and massive gauge boson (the massive photon), in addition to the massive off-diagonal gauge bosons (the massive non-Abelian spinons) which induces the spin-flip interaction between the spin up and down components of the Cooper pair. So, unlike the ordinary Landau-Ginzburg theory it has a long range interaction mediated by the massless non-Abelian spinon, which could be responsible for the long range magnetic order and spin waves observed in ferromagnetic superconductors. The theory is characterized by three scales. In addition to the correlation length fixed by the mass of the Higgs field it has two different penetration lengths, the one fixed by the mass of the photon (which generates the well known Meissner effect) and the other fixed by the mass of the off-diagonal spinons (which determines the scale of the spin flip interaction). The non-Abelian structure of the theory naturally accommodates new topological objects, the non-Abrikosov quantized spin vortex (as well as the well known Abrikosov vortex) and non-Abelian spin monopole. We discuss the physical implications of the non-Abelian Landau-Ginzburg theory.

Estimating the evolution of Sparks in Partially Screened Gap of Pulsars from Subpulse Drifting

description: A novel scheme has been developed to show that the observed phase behaviour associated with subpulse drifting from two pulsars, J1034$-$3224 and J1720$-$2933, can be used to obtain the magnetic field configuration in the partially screened gap (PSG). The outflowing plasma along the open magnetic field line region of pulsars is generated due to spark discharges in an inner acceleration region (IAR) above the polar cap. The IAR has been modelled as a partially screened gap (PSG) with a steady supply of positively charged ions emitted from the heated polar cap surface dominated by strong non-dipolar magnetic fields. In a PSG the sparks are tightly packed and constrained to be present along the polar cap boundary. The sparks lag behind the rotation of the star during their lifetimes. As a result the sparking pattern evolves along two different directions in the clockwise and counter-clockwise manner around a stationary central spark, and can be associated with the observed phenomenon of subpulse drifting. PSR J1034$-$3224 has four prominent components and exhibit bi-drifting where alternate components show opposite sense of drifting, while PSR J1720$-$2933 has a single component profile and shows systematic coherent drift bands. We show that the differences in their drifting behaviour can be directly linked to different natures of the non-dipolar surface magnetic field configurations.

description: The South Cushitic languages Gorwaa (ISO639-3: gow) and Iraqw (ISO639-3: irk) - both spoken in Tanzania by approximately 130,000 and 500,000 people, respectively – are among the small number of Cushitic languages spoken in the country, setting themselves apart by their phonology, grammar, as well as the wider cultures of their speaker communities. Linguists working from both outsider (Harvey 2019) and insider (Alphonce 2020) perspectives have argued that Gorwaa and Iraqw naming traditions are important conduits of local history, and are under considerable pressure from Christian, Muslim, and Swahili naming conventions. While both of the above works attempt an internal typology of Gorwaa and Iraqw names and naming, no attempt has been made to place them within the larger context of Tanzanian names and naming systems. This talk begins with a detailed discussion of names and naming in Gorwaa and Iraqw, distinguishing several independent mechanisms within the larger whole, including inherited, circumstantial, and talismanic names. Then, drawing on a wealth of newly-available analyses of names and naming in other Tanzanian languages, the Gorwaa and Iraqw systems are compared and contrasted with those present in Bantu-, Nilotic-, and Hadza-speaking communities.

Material examined.
China • Liaoning Province, Tieling City (42°17'22.3"N, 123°50'22.2"E), on a dead adult moth (Lepidoptera) on the stem of a plant, 25 August 2023, Ting-Chi Wen, HLJ 2023082515 (HKAS 144393).
Notes.
Phylogenetic analysis based on six gene markers revealed that the specimen HKAS 144393 and Akanthomyces baishanensis (CGMCC 3.25673 and CGMCC 3.25674) form a robustly supported monophyletic clade (100 % SH-aLRT / 100 % UFB / 1.00 PP, Fig. 1). Both HKAS 144393 and A. baishanensis exhibit parasitic relationships with adult moths. Notably, HKAS 144393 represents a naturally occurring asexual morph characterised by trimorphic conidiogenous structures, while the asexual morph of A. baishanensis described by Pu et al. (2025) was obtained from culture and displayed only a single type of conidiogenous structure. Our observations demonstrate greater morphological plasticity in this species than previously recognised.

The Theme of class in James Joyce's Dubliners
Creators: name: Clee, David Glyndwr
Publisher: name: University of British Columbia
Year: 2011

description: There is evidence throughout the stories, and in Joyce's letters, to show that Dubliners should be considered as a single entity rather than as a series of unconnected short stories. This thesis examines Joyce's presentation of Dublin's middle class as a unifying principle underlying the whole work. Joyce believed that his city was in the grip of a life-denying "paralysis", and this thesis studies his attempt in Dubliners to relate that paralysis to those attitudes towards experience which his Dubliners hold in common. The stories in Dubliners are grouped to form a progression from childhood through adolescence to maturity and public life. This progression reveals the nature of Dublin's middle class and its effect on its individual member throughout his life. Childhood is a time of comparative freedom, and adolescence shows the individual's increasing conformity to the standards and values of his class. By the time he reaches maturity he is totally trapped in that paralysis reflected in the corruption of the public institutions. The nature of the middle class is revealed by four sub-themes which I designate: "religion," "adventure", "love", and "culture". For the purposes of this analysis the stories are grouped according to these thematic divisions, but Joyce's own order is always taken into consideration. Chapters 1 to IV each examines one of these sub-themes. In Chapter V, "The Dead", which embraces all of these aspects of experience, is treated separately.

description: The interplay between vibrational modes and Kondo physics is a fundamental aspect of transport properties of correlated molecular conductors. We present theoretical results for a single molecule in the Kondo regime connected to left and right metallic leads, creating the usual coupling to a conduction channel with left-right parity ("even"). A center-of-mass vibrational mode introduces an additional, phonon-assisted, tunneling through the antisymmetric ("odd") channel. A non-Fermi liquid fixed point, reminiscent of the two-channel Kondo effect, appears at a critical value of the phonon-mediated coupling strength. Our numerical renormalization-group calculations for this system reveal non-Fermi-liquid behavior at low temperatures over lines of critical points. Signatures of this strongly correlated state are prominent in the thermodynamic properties and in the linear conductance.

description: Aims: The JWST program JOYS (JWST Observations of Young protoStars) aims at characterizing the physical and chemical properties of young high- and low-mass star-forming regions, in particular the unique mid-infrared diagnostics of the warmer gas and solid-state components. We present early results from the high-mass star formation region IRAS23385+6053. Methods: The JOYS program uses the MIRI MRS with its IFU to investigate a sample of high- and low-mass star-forming protostellar systems. Results: The 5 to 28mum MIRI spectrum of IRAS23385+6053 shows a plethora of features. While the general spectrum is typical for an embedded protostar, we see many atomic and molecular gas lines boosted by the higher spectral resolution and sensitivity compared to previous space missions. Furthermore, ice and dust absorption features are also present. Here, we focus on the continuum emission, outflow tracers like the H2, [FeII] and [NeII] lines as well as the potential accretion tracer Humphreys alpha HI(7--6). The short-wavelength MIRI data resolve two continuum sources A and B, where mid-infrared source A is associated with the main mm continuum peak. The combination of mid-infrared and mm data reveals a young cluster in its making. Combining the mid-infrared outflow tracer H2, [FeII] and [NeII] with mm SiO data shows a complex interplay of at least three molecular outflows driven by protostars in the forming cluster. Furthermore, the Humphreys alpha line is detected at a 3-4sigma level towards the mid-infrared sources A and B. Following Rigliaco et al. (2015), one can roughly estimate accretion luminosities and corresponding accretion rates between ~2.6x10^-6 and ~0.9x10^-4 M_sun/yr. This is discussed in the context of the observed outflow rates. Conclusions: The analysis of the MIRI MRS observations for this young high-mass star-forming region reveals connected outflow and accretion signatures.

Fall of a Particle to the Center of a Singular Potential: Classical vs. Quantum Exact Solutions

Subjects: subject: Quantum Physics (quant-ph)

description: Exact solutions describing a fall of a particle to the center of a non-regularized singular potential in classical and quantum cases are obtained and compared. We inspect the quantum problem with the help of the conventional Schrödinger's equation. During the fall, the wave function spatial localization area contracts into a single zero-dimensional point. For the fall-admitting potentials, the Hamiltonian is non-Hermitian. Because of that, the wave function norm occurs time-dependent. It demands an extension to this case of the continuity equation and rules for mean value calculations. Surprisingly, the quantum and classical solutions exhibit striking similarities. In particular, both are self-similar at the particle energy equals zero. The characteristic spatial scales of the quantum and classical self-similar solutions obey the same temporal dependence. We present arguments indicating that these self-similar solutions are attractors to a broader class of solutions, describing the fall at finite energy of the particle.

description: The three-particle $K$-matrix, $\mathcal{K}_{\mathrm{df},3}$, is a scheme-dependent quantity that parametrizes short-range three-particle interactions in the relativistic-field-theory three-particle finite-volume formalism. In this work, we compute its value for systems of three pions at maximal isospin through next-to-leading order (NLO) in Chiral Perturbation Theory (ChPT). We compare the values to existing lattice QCD results and find that the agreement between lattice QCD data and ChPT in the first two coefficients of the threshold expansion of $\mathcal{K}_{\mathrm{df},3}$ is significantly improved with respect to leading order once NLO effects are incorporated.

Bayesian Learning of Graph Substructures

description: Graphical models provide a powerful methodology for learning the conditional independence structure in multivariate data. Inference is often focused on estimating individual edges in the latent graph. Nonetheless, there is increasing interest in inferring more complex structures, such as communities, for multiple reasons, including more effective information retrieval and better interpretability. Stochastic blockmodels offer a powerful tool to detect such structure in a network. We thus propose to exploit advances in random graph theory and embed them within the graphical models framework. A consequence of this approach is the propagation of the uncertainty in graph estimation to large-scale structure learning. We consider Bayesian nonparametric stochastic blockmodels as priors on the graph. We extend such models to consider clique-based blocks and to multiple graph settings introducing a novel prior process based on a Dependent Dirichlet process. Moreover, we devise a tailored computation strategy of Bayes factors for block structure based on the Savage-Dickey ratio to test for presence of larger structure in a graph. We demonstrate our approach in simulations as well as on real data applications in finance and transcriptomics.

Clues to unveil the emitter in LS 5039: powerful jets vs colliding winds

description: LS 5039 is among the most interesting VHE sources in the Galaxy. Two scenarios have been put forward to explain the observed TeV radiation: jets vs pulsar winds. The source has been detected during the superior conjunction of the compact object, when very large gamma-ray opacities are expected. In addition, electromagnetic cascades, which may make the system more transparent to gamma-rays, are hardly efficient for realistic magnetic fields in massive star surroundings. All this makes unlikely the standard pulsar scenario for LS 5039, in which the emitter is the region located between the star and the compact object, where the opacities are the largest. Otherwise, a jet-like flow can transport energy to regions where the photon-photon absorption is much lower and the TeV radiation is not so severely absorbed.

title: A Study of Adequacy and Cost of Secondary School Guidance Programs in Utah
Creators: name: Wootton, Richard Roland
Publisher: name: Utah State University
Year: 1969

description: The study attempted to determine the current expenditures for secondary school guidance programs in Utah. In addition, the study attempted to evaluate the adequacy of selected guidance programs and to determine if a relationship existed between guidance expenditures and adequacy of guidance programs.
Fiscal data were collected, tabulated, and analyzed using financial reports from the Utah Office of Education. Further, response forms were administered to students, school administrators, counselors , and teachers in an attempt to elicit responses from these persons relative to their perceptions of guidance program adequacy in their respective schools.
Results indicated that Utah districts, as a group, spend 1.6 percent of their instructional budgets for guidance purposes. This figure is considerably below the three percent usually recommended in the current literature as being necessary for a "minimum" guidance program. Significant differences were observed in the per pupil expenditures between National Defense Education Act, Title V participants and non- participants with the participants allocating the greater amount .Metropolitan districts were observed to be making significantly greater per pupil expenditures than districts with smaller populations. No significant differences were found in the number of "yes," or positive responses, of students or teachers from "minimum" and "maximum" spending effort schools.
A general conclusion was reached that Utah districts do not presently allocate percentages of instructional budgets that will allow them to develop or maintain sound guidance programs. Either larger budgetary consideration should be provided or else it should be clearly recognized by educators and the lay public that guidance programs that appear to be inadequate may be the result, in part, of unrealistic financing.
A general recommendation that encompasses several others presented in the study is that a total re-evaluation of fiscal policies, practices, allocation procedures, and record keeping for guidance programs is in order. Improvement of budgetary practices and guidance programs are such that changes cannot be expected without increased awareness and commitment by counselor educators, administrators, parents, State Office of Education officials, and counselors. Without such an awareness and commitment; we cannot expect to observe a change from undesirable budgetary practices and relatively unsound guidance programs now found in Utah.
