description: Ultra Reliable Low Latency Communications (URLLC) is an important challenge for the next generation wireless networks, which poses very strict requirements to the delay and packet loss ratio. Satisfaction is hardly possible without introducing additional functionality to the existing communication technologies. In the paper, we propose and study an approach to enable URLLC in Wi-Fi networks by exploiting an additional radio similar to that of IEEE 802.11ba. With extensive simulation, we show that our approach allows decreasing the delay by orders of magnitude, while the throughput of non-URLLC devices is reduced insignificantly.

description: Over $1.7 billion has been spent on the Conservation Reserve Program (CRP) since 1985. The purpose of this study is to show that these expenditures have aided the environment. Rather than quantify changes in environmental variables, a spatial econometric model is used to test if CRP enrollments are greater in counties with poorer environmental quality. In seven of nine regions, CRP enrollments are higher in counties with an environmental concern. This positive finding justifies past expenditures by the CRP and supports continued funding as an environmental program. The CRP is targeting current environmental concerns that will lead to future improvement.

description: Purpose: This study aimed to identify the current practices of New Zealand speech–language pathologists (SLPs) working with multilingual children, to compare these with best practice guidelines and make recommendations for training and service development. Method: An online survey was sent to SLPs working with children in New Zealand, asking questions about their training, languages spoken and management of multilingual children. Result: Responses from 146 SLPs were analysed. While 28% reported over 25% of children on their caseloads were multilingual, most SLPs felt under-trained to work with these clients. In accordance with best practice guidelines, SLPs supported retention of home languages for their multilingual children. Half of the children seen were assessed and treated in all languages, despite the majority of SLPs being monolingual English speakers. However contrary to best practice recommendations, parents were used as interpreters more frequently than professional interpreters. The SLPs reported a lack of resources for assessment and treatment of multilingual children. Informal assessments were frequently used, but dynamic assessment and peer-child comparisons were under-utilised. Conclusion: There were marked differences between SLPs’ current practice with multilingual children and best practice guidelines. Increased training opportunities along with resource development in languages commonly spoken in New Zealand are required.
Probabilistic testing of Boolean functions, or, How to test locally for a global property
Creators: name: Majewski, Krzysztof Michał
Publisher: name: University of British Columbia
Year: 2009

description: Probabilistic testing is a general problem that has fundamental scientific value as well as direct applications to important concepts in theoretical computer science, such as probabilistically checkable proofs (PCP). We consider specifically the testing of Boolean functions, discussing some key existing results and providing new results for several classes of functions. In particular, we give efficient tests for a Boolean function to be symmetric (invariant under permutation of its variables) and quasi-symmetric (a symmetric function of the variables it actually depends on).

description: Changes to commodity programs in the 2002 Farm Bill increased the value of crop base acreages on which decoupled payments are received. The bill also expanded the availability of key conservation programs. This paper compares the value of payments from commodity programs (along with continued crop production) to the easement payment (and recreational lease revenue) available under the Wetland Reserve Program. A net present value model using risk-adjusted returns is employed in the analysis for Mississippi delta cropland containing rice, cotton, and soybean base. Sensitivity analysis is conducted on some of the key variables affecting the decision.

description: Conservation reserve program (CRP) payments amount to several billion dollars annually. Payments are allocated to both remove land from production and to help farmers pay for conservation improvements. However, research examining whether farmers increase their utility with CRPs is limited. This paper uses simulation analysis and certainty equivalents to compare farming income to payments under the CRP. Farming income is a combination of crop production and government payments as specified in the 2002 Farm Bill. This analysis focuses on farms in three different counties in Kentucky. Results indicate that CRPs are good choices for many farmers.

description: We review observations and gravitational lensing theory related to the magnification of background QSOs by intervening overdensities, and the induced cross-correlation between sources and foreground galaxies. We pay special attention to simulations, and present some preliminary results from high resolution cluster simulations, which show the role of the halo core and substructure on non-linear magnification. For massive clusters, deviations from the weak gravitational lensing regime are significant on arcmin scales and bellow. The accumulated knowledge in the field already shows that gravitational lensing magnification is an important astrophysical and cosmological tool.

description: The temperature gradient of microwave background radiation (CMBR) is calculated in the Self Consistent Model. An expected values for Hubble parameter have been presented in two different cases. In the first case the temperature is treated as a function of time only, while in the other one the temperature depends on relaxation of isotropy condition in the self-consistent model and the assumption that the universe expands adiabatically. The COBE's or WMAP's fluctuations in temperature of CMBR may be used to predict a value for Hubble parameter.

description: Purpose: Yolŋu are Aboriginal Australians from northeast Arnhem Land in the Northern Territory (NT). Machado–Joseph disease (MJD) prevalence in the NT Aboriginal population is the highest in the world. Yolŋu living with progressive dysarthria associated with MJD could benefit from augmentative and alternative communication (AAC). However, there are no aided AAC systems in Yolŋu languages. This research aimed to explore the views of Yolŋu with MJD about communication, speech-language pathology (SLP) services and AAC. Method: A collaborative, culturally responsive research design was informed by Indigenist Research methodology and Constructivist Grounded Theory. Yolŋu with MJD (n = 10) and their interested family members (n = 4) participated in interviews and created visual representations of their social networks. Data were analysed through an oral interpretive process with Yolŋu researchers. Result: A Yolŋu metaphor, Goŋdhu “Building understanding by hand”, emerged as a culturally meaningful way to represent the core understandings required for speech-language pathologists (SLPs) to work effectively with Yolŋu with MJD. Elements of this metaphor include seeking to understand the complex lived experiences of Yolŋu with MJD, and working with families to explore the potential benefits of SLP services and AAC. Conclusion: Yolŋu with MJD and their families want to work collaboratively with SLPs to develop bilingual AAC systems and culturally responsive SLP services that build on strengths of Yolŋu culture and kinship to improve communication opportunities and participation.
Active Region Irradiance During Quiescent Periods: New Insights from Sun-as-a-star Spectra

description: How much energy do solar active regions (ARs) typically radiate during quiescent periods? This is a fundamental question for storage and release models of flares and ARs, yet it is presently poorly answered by observations. Here we use the "Sun-as-a-point-source" spectra from the EUV Variability Experiment (EVE) on the Solar Dynamics Observatory (SDO) to provide a novel estimate of radiative energy losses of an evolving active region. Although EVE provides excellent spectral (5-105nm) and temperature (2-25MK) coverage for AR analysis, to our knowledge, these data have not been used for this purpose due to the lack of spatial resolution and the likelihood of source confusion. Here we present a way around this problem. We analyze EVE data time series, when only one large AR 11520 was present on the disk. By subtracting the quiet Sun background, we estimate the radiative contribution in EUV from the AR alone. We estimate the mean AR irradiance and cumulative AR radiative energy losses in the 1-300A and astronomical standard ROSAT-PSPC, 3-124A, passbands and compare these to the magnetic energy injection rate through the photosphere, and to variations of the solar cycle luminosity. We find that while AR radiative energy losses are ~100 times smaller than typical magnetic energy injection rates at the photosphere, they are an order of magnitude larger or similar to the bolometric radiated energies associated with large flares. This study is the first detailed analysis of AR thermal properties using EVE Sun-as-a-star observations, opening doors to AR studies on other stars.

description: Purpose: To determine the most effective intervention for adults with social communication impairments due to an Acquired Brain Injury (ABI), using standardised outcome measures completed by significant others. Method: A systematic literature review was conducted. Four electronic databases relevant to the field of speech-language pathology or brain injury were searched: Medline, CINAHL, AMED and Embase. Grey literature, reference lists and citation indexes were also hand searched for additional research. Studies that met the broad inclusion and exclusion criteria were initially screened to determine articles for full text reviews by two independent reviewers. Reviewers independently extracted data from full-text reviews using a data extraction form and performed bias analysis using the Downs and Black quality checklist (Downs, S.H., & Black, N. (1998). The feasibility of creating a checklist for the assessment of the methodological quality both of randomised and non-randomised studies of health care interventions. Journal of Epidemiology & Community Health, 52, 377–384.). Studies were categorised using a five-phase model of evidence (Robey, R.R., & Schultz, M.C. (1998). A model for conducting clinical-outcome research: An adaptation of the standard protocol for use in aphasiology. Aphasiology, 12, 787–810.). Result: 681 articles were identified after duplicates were removed. 15 articles were reviewed for full-text analysis. Six studies were ultimately included in the review. Of these, three were randomised controlled trials and three others were not. Four studies delivered intervention solely to the individual with an ABI, one to the communication partner only, and one delivered intervention both to the individual and their communication partner. Intervention programmes ranged from four to 12 weeks and from 12 to 48 hours total contact time. The reviews studies were heterogeneous, which made comparisons difficult. Risk of bias was also present to varying degrees in all studies. The current level of evidence has focussed on efficacy of treatments and effectiveness of treatment is not yet established. Conclusion: The current level of evidence is not yet established to make clear clinical guidelines on which interventions are most effective, based on significant others’ reports. Further research is required, incorporating more rigorous study designs and larger sample sizes to enable accurate conclusions to be drawn.

description: The existence of resonant enhanced transmission and collimation of light waves by subwavelength slits in metal films [for example, see T.W. Ebbesen et al., Nature (London) 391, 667 (1998) and H.J. Lezec et al., Science, 297, 820 (2002)] leads to the basic question: Can a light pulse be enhanced and simultaneously localized in space and time by a subwavelength slit? To address this question, the spatial distribution of the energy flux of an ultrashort (femtosecond) wave-packet diffracted by a subwavelength (nanometer-size) slit was analyzed by using the conventional approach based on the Neerhoff and Mur solution of Maxwell's equations. The results show that a light pulse can be enhanced by orders of magnitude and simultaneously localized in the near-field diffraction zone at the nm- and fs-scales. Possible applications in nanophotonics are discussed.

Forty-eight percent of the variation in first-semester college grades was explained by high school grades, standardized test scores, socioeconomic variables, high school characteristics, credit hours completed, and major field of study. Approximately 62% of the variation in second-semester grades was explained. First-semester college grades explained 43% of second-semester grades. Several statistically significant relationships are detected, and the implications for students, advisors, and administrators are discussed.

description: We calculate the electrical and thermal conductivity of a two-dimensional electron gas with strong spin--orbit coupling in which the scattering is dominated by electron--electron collisions. Despite the apparent absence of Galilean invariance in the system, the two-particle scattering does not affect the electrical conductivity above the band-crossing point where both helicity bands are filled. Below the band-crossing point where one helicity band is empty, switching on the electron--electron scattering leads only to a limited decrease of the electrical conductivity, so that its high-temperature value is independent of the scattering intensity. In contrast to this, thermal conductivity is not strongly affected by the spin-orbit coupling and exhibits only a kink as the Fermi level passes through the band-crossing point.

description: The thermal radiation of small conducting particles was investigated in the region where the Stephan-Boltzmann law is not valid and strongly overestimates radiation losses. The new criterion for the particle size, at which black body radiation law fails, was formulated. The approach is based on the magnetic particle polarization, which is valid until very small sizes (cluster size) where due to drop of particle conductivity the electric polarization prevails over the magnetic one. It was also shown that the radiation power of clusters, estimated on the basis of the experimental data, is lower than that given by the Stephan-Boltzmann law.

description: This article analyzes anomalous patterns of agent, adjuster, and producer claim outcomes and determines the most likely pattern of collusion that is suggestive of fraud, waste, and abuse in the federal crop insurance program. Log-linear analysis of Poisson-distributed counts of anomalous entities is used to examine potential patterns of collusion. The most likely pattern of collusion present in the crop insurance program is where agents, adjusters, and producers nonrecursively interact with each other to coordinate their behavior. However, if a priori an intermediary is known to initiate and coordinate the collusion, a pattern where the producer acts as the intermediary is the most likely pattern of collusion evidenced in the data. These results have important implications for insurance program design and compliance.

We show that in this setting, classical theories and intuitions do not hold, and various counter intuitive dynamics are possible. In particular, the weaker competitor could avoid competitive exclusion, and the slower diffuser may not win. Numerical simulations are performed to verify our analytical findings.

The ground state properties of the integrable two-leg spin-1/2 and the mixed spin-(1/2,1) ladder models at zero temperature are analyzed by means of the Thermodynamic Bethe Ansatz. Solving the TBA equations yields exact results for the critical fields and critical behaviour. The thermal and magnetic properties of the models are investigated in terms of the recently introduced High Temperature Expansion method, which is discussed in detail. It is shown that in the strong coupling limit the integrable spin-1/2 ladder model exhibits three quantum phases: (i) a gapped phase in the regime $HH_{c2}$, and (iii) a Luttinger liquid magnetic phase in the regime $H_{c1}

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We consider a matrix model description of the 2d string theory whose matter part is given by a time-like linear dilaton CFT. This is equivalent to the c=1 matrix model with a deformed, but very simple fermi surface. Indeed, after a Lorentz transformation, the corresponding 2d spacetime is a conventional linear dilaton background with a time-dependent tachyon field. We show that the tree level scattering amplitudes in the matrix model perfectly agree with those computed in the world-sheet theory. The classical trajectories of fermions correspond to the decaying D-branes in the time-like linear dilaton CFT. We also discuss the ground ring structure. Furthermore, we study the properties of the time-like Liouville theory by applying this matrix model description. We find that its ground ring structure is very similar to that of the minimal string.

Here we report the ALD growth of SiO$_{2}$/GeO$_{2}$ multilayers on Silicon substrates using a so far unreported Ge precursor. The characterization of multilayers with various periodicities reveals successful layer-by-layer growth with electron density contrast and absence of chemical intermixing, down to a periodicity of 2 atomic layers.

description: We study the relationship between the off-farm labor decision and the limited-resource farmers’ and spouses’ off-farm experience, education, and sources of income. We found that farmers’ and spouses’ off-farm experience and wages are significant factors in explaining the off-farm labor supply decision. Contrary to expectations, farm income variability is not significant in the farmers’ and spouses’ decision to see off-farm work. The off-farm labor supply of farmers and their spouses is negatively correlated with income transfers from the government. It was also found that the spouse is a residual supplier of on-farm and off-farm labor.

description: The fully consistent relativistic proton-neutron quasiparticle random phase approximation (PN-RQRPA) is employed in the calculation of beta-decay half-lives of neutron-rich nuclei in the N$\approx$50 and N$\approx$82 regions. A new density-dependent effective interaction, with an enhanced value of the nucleon effective mass, is used in relativistic Hartree-Bogoliubov calculation of nuclear ground states and in the particle-hole channel of the PN-RQRPA. The finite range Gogny D1S interaction is employed in the T=1 pairing channel, and the model also includes a proton-neutron particle-particle interaction. The theoretical half-lives reproduce the experimental data for the Fe, Zn, Cd, and Te isotopic chains, but overestimate the lifetimes of Ni isotopes and predict a stable 132Sn.

description: Purpose: Yolŋu are Aboriginal Australians from northeast Arnhem Land in the Northern Territory (NT). Machado–Joseph disease (MJD) prevalence in the NT Aboriginal population is the highest in the world. Yolŋu living with progressive dysarthria associated with MJD could benefit from augmentative and alternative communication (AAC). However, there are no aided AAC systems in Yolŋu languages. This research aimed to explore the views of Yolŋu with MJD about communication, speech-language pathology (SLP) services and AAC. Method: A collaborative, culturally responsive research design was informed by Indigenist Research methodology and Constructivist Grounded Theory. Yolŋu with MJD (n = 10) and their interested family members (n = 4) participated in interviews and created visual representations of their social networks. Data were analysed through an oral interpretive process with Yolŋu researchers. Result: A Yolŋu metaphor, Goŋdhu “Building understanding by hand”, emerged as a culturally meaningful way to represent the core understandings required for speech-language pathologists (SLPs) to work effectively with Yolŋu with MJD. Elements of this metaphor include seeking to understand the complex lived experiences of Yolŋu with MJD, and working with families to explore the potential benefits of SLP services and AAC. Conclusion: Yolŋu with MJD and their families want to work collaboratively with SLPs to develop bilingual AAC systems and culturally responsive SLP services that build on strengths of Yolŋu culture and kinship to improve communication opportunities and participation.

description: Radiatively-induced gravitational leptogenesis is a potential mechanism to explain the observed matter-antimatter asymmetry of the universe. Gravitational tidal effects at the quantum loop level modify the dynamics of the leptons in curved spacetime and may be encoded in a low-energy effective action Seff. It has been shown in previous work how in a high-scale BSM theory the CP odd curvature-induced interactions in Seff modify the dispersion relations of leptons and antileptons differently in an expanding universe, giving rise to an effective chemical potential and a non-vanishing equilibrium lepton-antilepton asymmetry. In this paper, the CP even curvature interactions are shown to break lepton number current conservation and modify the evolution of the lepton number density as the universe expands. These effects are implemented in a generalised Boltzmann equation and used to trace the dynamical evolution of the lepton number density in different cosmological scenarios. The theory predicts a potentially significant gravitationally-induced lepton-antilepton asymmetry at very early times in the evolution of the universe.

Does gas Flaring affect Biochemical Parameters? Evidence from a Nigerian Oil-Bearing Community

description: Upon the discovery of crude oil, Nigerian economy experienced an interesting leap. Agriculture suffered a setback because so much attention was moved to oil exploration since it accounted for over 70% of the country's foreign exchange earnings. However, oil exploitation precipitated the problem of gas flaring since Nigeria is endowed with more gas reserves than oil (Ashton-Jones, 1998). Gas flaring is the burning of natural gas that is associated with petroleum production while releasing hazardous compounds into the air. United States energy Information Administrative International energy statistics database (2023) reported that Nigeria flared about 5.318 billion cubic meters of natural gas in 2022 making Nigeria the 9th-highest natural gas flaring country in terms of annual natural gas flaring volume. Some of the hazardous compounds that gas flaring releases into the air are alkanes, alkenes, volatile organic compounds (VOC), polycyclic aromatic hydrocarbons, naphthalene, styrene, acetylene, fluoranthene, anthracene, pyrene, xylene, ethylene, soot, greenhouse gases and carbon monoxide. Also, heavy metals are not excluded. I went on a tour to Ibeno, a gas faring community. As I discussed with the locals, they complained bitterly of experiencing so much hazards as a result of gas flaring. This led to the decision to embark on this journey in an attempt to scientifically validate or invalidate their claims.

description: This paper characterizes the optimal use of sanitary and phytosanitary standards to prevent the introduction of harmful pests and diseases through international trade. Because established pest and disease infestations grow and spread over time their introduction has intertemporal consequences. In a dynamic economic model, an efficient trade policy balances the costs of SPS measures against the discounted stream of the costs of control and social damages that are avoided by using SPS measures, where future growth and spread of any established infestation is accounted for. We examine when phytosanitary trade policy makes good economic sense, when it is efficient to provide full protection against pests and diseases, and when restrictive, but not fully protective trade policy is efficient.

Stellar Rotation in Young Clusters. II. Evolution of Stellar Rotation and Surface Helium Abundance

description: We derive the effective temperatures and gravities of 461 OB stars in 19 young clusters by fitting the H-gamma profile in their spectra. We use synthetic model profiles for rotating stars to develop a method to estimate the polar gravity for these stars, which we argue is a useful indicator of their evolutionary status. We combine these results with projected rotational velocity measurements obtained in a previous paper on these same open clusters. We find that the more massive B-stars experience a spin down as predicted by the theories for the evolution of rotating stars. Furthermore, we find that the members of binary stars also experience a marked spin down with advanced evolutionary state due to tidal interactions. We also derive non-LTE-corrected helium abundances for most of the sample by fitting the He I 4026, 4387, 4471 lines. A large number of helium peculiar stars are found among cooler stars with Teff < 23000 K. The analysis of the high mass stars (8.5 solar masses < M < 16 solar masses) shows that the helium enrichment process progresses through the main sequence (MS) phase and is greater among the faster rotators. This discovery supports the theoretical claim that rotationally induced internal mixing is the main cause of surface chemical anomalies that appear during the MS phase. The lower mass stars appear to have slower rotation rates among the low gravity objects, and they have a large proportion of helium peculiar stars. We suggest that both properties are due to their youth. The low gravity stars are probably pre-main sequence objects that will spin up as they contract. These young objects very likely host a remnant magnetic field from their natal cloud, and these strong fields sculpt out surface regions with unusual chemical abundances.

description: We provide updated predictions for the hadronic decays $\bar{B}_s^0\to D_s^{(*)+} π^-$ and $\bar{B}^0\to D^{(*)+} K^-$. They are based on $\mathcal{O}(α_s^2)$ results for the QCD factorization amplitudes at leading power and on recent results for the $\bar{B}_{(s)} \to D_{(s)}^{(*)}$ form factors up to order ${\cal O}(Λ_{\rm QCD}^2/m_c^2)$ in the heavy-quark expansion. We give quantitative estimates of the matrix elements entering the hadronic decay amplitudes at order ${\cal O}(Λ_{\rm QCD}/m_b)$ for the first time. Our results are very precise, and uncover a substantial discrepancy between the theory predictions and the experimental measurements. We explore two possibilities for this discrepancy: non-factorizable contributions larger than predicted by the QCD factorization power counting, and contributions beyond the Standard Model. We determine the $f_s/f_d$ fragmentation fraction for the CDF, D0 and LHCb experiments for both scenarios.
