description: A method for measuring an integral of a classical field via local interaction of a single quantum particle in a superposition of 2^N states is presented. The method is as efficient as a quantum method with N qubits passing through the field one at a time and it is exponentially better than any known classical method that uses N bits passing through the field one at a time. A related method for searching a string with a quantum particle is proposed.

description: In this work, we explore the possibilities of producing Axion-Like Particles (ALPs) in a future $e^-p$ collider. Specifically, we focus on the proposed Large Hadron electron collider (LHeC), which can achieve a center-of-mass energy of $\sqrt{s} \approx 1.3$~TeV, enabling us to probe relatively high ALP masses with $m_a \lesssim 300$~GeV. The production of ALPs can occur through various channels, including $W^+W^-$, $γγ$, $ZZ$, and $Zγ$-fusion within the collider environment. To investigate this, we conduct a comprehensive analysis that involves estimating the production cross section and constraining the limits on the associated couplings of ALPs, namely $g_{WW}$, $g_{γγ}$, $g_{ZZ}$, and $g_{Zγ}$. To achieve this, we utilize a multiple-bin $χ^2$ analysis on sensitive differential distributions. Through the analysis of these distributions, we determine upper bounds on the associated couplings within the mass range of 5~GeV $\leq m_a \leq$ 300~GeV. The obtained upper bounds are of the order of ${\cal O}(10^{-1})$ for $g_{γγ}$ ($g_{WW}$, $g_{ZZ}$, $g_{Zγ}$) in $m_a \in$~[5, 200 (300)]~GeV considering an integrated luminosity of 1~ab$^{-1}$. Furthermore, we compare the results of our study with those obtained from other available experiments. We emphasize the limits obtained through our analysis and showcase the potential of the LHeC in probing the properties of ALPs.

title: Sub-cellular localization and regulatory mechanisms of AMPA receptors in motor neurons of a murine model of familial Amyotrophic Lateral Sclerosis
Creators: name: Veglianese, Peitro
Publisher: name: The Open University
Year: 2007

description: Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease leading to progressive muscle wasting and paralysis and premature death. The disease is predominantly sporadic (sALS) in nature with approximately 10% of case inherited (familial ALS). In the present study, I have examined the subcellular distribution and expression of the AMPA receptor subunits and the proteins involved in their trafficking between the cytosol and postsynaptic membrane (ABP, PICK1 and NSF) in a mouse model of familial ALS (SOD1G93A mice) at different stages of the disease. The main finding was a decrease of GluR2 AMPA receptor subunit selectively in cytosol, but not in synaptic membrane of spinal motor neurons of SOD1G93A mice before symptoms onset. This suggests that an impairment in the usually well-organized trafficking of the GluR2 AMPA is likely the cause of the increased degradation of this receptor subunit. In support of this, increased level of the trafficking protein NSF, able to increase the delivery of GluR2 at the cell surface, was reported selectively in the motor neurons at the presymptomatic stage of the disease in SOD1G93A mice. Since GluR2 plays an important role in regulating the calcium entrance in the cells by the AMPA receptors, I hypothesise that the increase of NSF may be an attempt to protect motor neurons from excitotoxicity by maintaining the sufficient levels of GluR2 subunit in the membrane. However, since an overall degradation of this subunit occurs in the motor neurons, this effect is probably no longer efficacious. At symptomatic and end stage of the disease increased immunoreactivity of GluRl, 2 and 3 AMPA receptor subunits was found in the activated glial cells. Although there are evidences of a role of reactive glia in favouring the neuronal excitotoxicity, the relevance of this effect needs to be investigated.

description: This research examines what is required to introduce new instructional technology---in the form of distance educational technology---into the corporate arena. The importance and need to attain lifelong learning in today's society is obvious, however, learning can be provided for corporations via online education. Distance educational technology has become a catalyst for constant change and upgrading of skills and work processes, a change based on how processes may be improved and upon people's skills in the corporate arena. While some corporate educational training programs are experimenting with distance educational technology, many are failing because they are not sufficiently implementing the full range of pedagogy. For successful implementation, particularly in the corporate distance education arena, a fundamental and authentic pedagogy must be incorporated into the curriculum in order for genuine learning to transpire (Dede, 1999). The corporate distance educational curricular environment is no different than any educational curriculum: Without an educational pedagogy, the purpose of the distance educational environment to learn is contradicted. This study examined constructivist pedagogy utilization within the arena of corporate distance education. The researcher queried several experts via web-based surveys and superlative interview techniques. Although the demographic population queried was a selected sample group, all respondents have experience in technology and education thus, they were able to comprehend the magnitude of pedagogy. Specifically, the sample population understood the significance of a particular pedagogy, such as constructivistism, and how it could enhance or maintain effective learning to take place. This research confirmed that in order for a corporate distance educational program to be deemed effective and successful, the constructivist pedagogy must be implemented. Therefore, the most critical conclusion of this research established that regardless of "cutting edge" technology, some of the most traditional characteristics of the constructivist pedagogy must be tied to the curriculum in order for it to be successful. Since the constructivist models have emerged from the works of many traditional educational theorists such as Bruner, Piaget, Dewey, and Vygotsky, the remarkable findings are that the most fundamental elements in successful learning environments can be applied into innovative classrooms, including the corporate distance education classroom.

Cavity and anisotropy effects are investigated and demostrated to play a central role in the transverse mode dynamics. While the idler beam can oscillate in a Laguerre-Gauss mode, the crystal birefringence induces an astigmatic effect in the signal beam that prevents the resonance of such mode.

description: Coronal dimmings - transient regions of strongly reduced emission in soft X-rays (SXR) and extreme ultraviolet (EUV) emission that occur in association with CMEs in the low corona and are interpreted to be density depletions due to the evacuation of plasma. We studied 43 coronal dimming events associated with Earth-directed coronal mass ejections (CMEs) that were observed in quasi-quadrature by the SDO and STEREO satellites. We derived the properties of the dimmings as observed above the limb by STEREO EUVI, and compared them with the mass and speed of the associated CMEs. The unique satellite constellation allowed us to compare our findings with the results from Dissauer et al. (2018, 2019), who studied these events observed against the solar disk by SDO AIA. Such statistics is done for the first time and confirms the close relation between characteristic dimming and CME parameters for the off-limb viewpoint. We find that the dimming areas are typically larger for off-limb observations (mean value of 1.24±1.23×1011 km2 against 3.51±0.71×1010 km2 for on-disk), while the decrease in the total extreme ultraviolet intensity is similar (c=0.60±0.14). The off-limb dimming areas and brightnesses are strongly correlated with the CME mass (c=0.82±0.06 and 0.75±0.08), whereas the dimming area and brightness change rate correlate with the CME speed (c∼0.6). Our findings suggest that coronal dimmings have the potential to provide early estimates of the Earth-directed CMEs parameters, relevant for space weather forecasts, for satellite locations at both L1 and L5.

description: At the turn of the 20th to 21st century, ghost films experienced an unexpected boom in East and Southeast Asia. This cultivation of ‘angstlust’ needs to be explained, as does the omnipresence of vengeful undead in the cinema. This article deals with the emergence of the East and Southeast Asian horror genre since the late 1990s. Ghost films reflect and comment on the imposition of modernity for individuals and society. The narratives of some transnational ghost films from Japan, Korea, Hong Kong, Thailand and Singapore serve as illustrative material. Three interpretative approaches are offered in order to better understand the cinematically generated presence of the undead: ghost films and the dark sides of modernity, ghost films as post-mortem and/or mindgame movies, ghost films and family secrets.

description: We show that finite lattices with arbitrary boundaries may support large degenerate subspaces, stemming from the underlying translational symmetry of the lattice. When the lattice is coupled to an environment, a potentially large number of these states remains weakly or perfectly uncoupled from the environment, realising a new kind of bound states in the continuum. These states are strongly localized along particular directions of the lattice which, in the limit of strong coupling to the environment, leads to spatially-localized subradiant states.

An empirical evaluation of the economic determinants and impacts of labor standards
Creators: name: Vijaya, Ramya
Publisher: name: American University
Year: 2023

description: This dissertation conducts an empirical evaluation of the economic determinants and the economic impact of labor standards. In doing so it hopes to move away from the narrow focus in the literature on the ambiguous relationship between trade and labor standards and view the latter as an evolving process that is embedded within a broader economic context. Viewing labor standards as an evolving process also helps to develop a better framework to understand the varied links between trade, particularly exports, and labor standards. In order identify the economic factors that influence the dynamic evolution of labor standards a two period optimization model is developed. The model incorporates the various short-run and long-run implications of adopting higher labor standards and derives an empirical equation with labor standards as the endogenous variable. The economic impact of labor standards is linked to improvements in labor productivity. In order to test this impact a stochastic production frontier approach is used. The empirical analysis is conducted with the help of a labor standards index. The cross-country times series index has been specifically constructed to overcome some of the shortcomings of previous measures. The significant conclusions from this research are that the influences on labor standards differ by levels of economic development. For countries above a threshold of development, income and factors like exports that have a potential positive impact on income, have a positive impact on labor standards in the long run. However for countries with very low levels of development do not experience this positive income impact on labor standards. Investments in education are the only positive influence on standards across all levels of development. Therefore raising standards globally cannot be achieved through a simple legislative process alone. Substantial and country specific investments in human capital are required. The results also indicate that in the short run exports tend to diminish the importance of labor productivity gains from higher labor standards.

description: We study the effects of thermal fluctuations of gluons and the diquark pairing field on the superconducting-to-normal state phase transition in a three-flavor color superconductor, using the Ginzburg-Landau free energy. At high baryon densities, where the system is a type I superconductor, gluonic fluctuations, which dominate over diquark fluctuations, induce a cubic term in the Ginzburg-Landau free energy, as well as large corrections to quadratic and quartic terms of the order parameter. The cubic term leads to a relatively strong first order transition, in contrast with the very weak first order transitions in metallic type I superconductors. The strength of the first order transition decreases with increasing baryon density. In addition gluonic fluctuations lower the critical temperature of the first order transition. We derive explicit formulas for the critical temperature and the discontinuity of the order parameter at the critical point. The validity of the first order transition obtained in the one-loop approximation is also examined by estimating the size of the critical region.

description: Palm oil expansion in Indonesia is associated with both a reduction in biodiversity and ecosystem services, and livelihood improvements for smallholder farmers. While this dichotomy highlights the importance of sustainable management options, empirical evidence on which policies are effective in stimulating biodiversity-friendly plantation management is relatively scarce. This paper addresses this gap by presenting results from a Randomized Controlled Trial implemented in Jambi province, Sumatra, in 2016. We focus on tree nuclei planting in oil palm plantations as one sustainable management option. To test whether information and input provision affect smallholders tree enrichment activities, two treatments were designed: the first provided information about tree planting in oil palm, while the second combined information and input delivery. We model adoption in a double-hurdle framework where farmers first decide whether to adopt or not and then how many trees they plant per hectare. Our results suggest that both interventions are effective in stimulating tree planting in oil palm. While input provision in combination with information leads to a higher probability of adoption, farmers plant on average relatively few trees per hectare. In contrast, in the informational treatment, few farmers enrich but they plant more trees per hectare than farmers who received saplings.

description: Based on a large qualitative study the paper confirms previous and provides interesting new insights into societal acceptance of current animal husbandry in Germany. Regarding perception and evaluation of animal husbandry two concepts and visual depictions are dominant. In this paper, we name them museums husbandry and mass animal production whereby the first describes a common feeling about an acceptable way of animal husbandry while the opposite holds for the latter which is perceives as a rotten system driven by greed. Omnivores feel entangled in this system and deal with the meat paradox by finding excuses for their behavior. Interviewees felt guilt and concern to a different extend. No one really accepted what they perceived as the current way of animal husbandry, but tolerance was quite diverse among participants. The latter implies to be willing to go on with the system because of the many benefits linked to it. Moreover, it has to be taken into account that not own experience but media and peoples fantasies and horror scenarios as well as their longings drive perception of animal welfare. That leads to the question to what extend potential future adjustments in animal husbandry change peoples perception.

description: We investigate the high energy emission activities of two bright gamma-ray pulsars, PSR~J2021+4026 and Vela. For PSR~J2021+4026, the state changes in the gamma-ray flux and spin-down rate have been observed. We report that the long-term evolution of the gamma-ray flux and timing behavior of PSR~J2021+4026 suggests a new gamma-ray flux recovery at around MJD~58910 and a flux decrease around MJD~59500. During this epoch, the staying time, the gamma-ray flux difference and spin-down rate are smaller than previous epochs in the same state. The waiting timescale of the quasi-periodic state changes is similar to the waiting timescale of the glitch events of the Vela pulsar. For the Vela pulsar, the quench of the radio pulse was in a timescale of $\sim0.2$~s after the 2016 glitch, and the glitch may disturb the structure of the magnetosphere. Nevertheless, we did not find any evidence for a long-term change in the gamma-ray emission properties using years of $Fermi$-LAT data, and therefore, no long-term magnetosphere structural change. We also conduct searching for photons above 100~GeV using 15-year $Fermi$-LAT data, and found none. Our results provide additional information for the relation between the state change of the gamma-ray emission and the glitch event.

description: In recent years, sales of commercial nutritionally enhanced complementary food are very common land scape in developing countries. However, whether this phenomenon can improve child nutrition or not is ambiguous. This study explore the impact of appearance of new commercial supplementary food product on child nutrition by means of randomized sales experiment. We use definitely new product for impact evaluation of market based approach. Therefore we can evaluate the impact of appearance and prevalence of the commercial product. The results shows there are heterogeneous impact of the product. The consumption of the product has statistically significant and positive impacts on child weight only for initially less-weighted children, but not for initially well-weighted children. Our results show the market based approach is effective way for improvement of child nutrition in Ghana. Acknowledgement :

description: Among the vast variety of proposals put forward by the community to resolve tree-level unitarity violations in Higgs inflation models, there exists the concept of self-healing. It heals the theory from supposed tree-level violations for elastic scattering processes by summing over successive vacuum polarization loop corrections. In this work, we examine this technique to check whether unitarity is indeed restored and find that there exist underlying constraints in self-healing unitarity that pose the same perturbative unitarity bounds that it was expected to heal.

description: Wormhole configurations in Einstein's general theory of relativity (GR) require exotic matter sources violating the weak energy condition (WEC). Rastall's theory is a generalization of GR in its matter source considering a nonconserved energy-momentum (EM) tensor. Hence, on one hand, the nature of this generalization of the matter source of field equations and, on the other hand, the possibility of respecting energy conditions for dynamical wormholes in contrast to static ones motivates us to study the possibility of the existence of wormhole configurations respecting energy conditions or minimizing the violations of them in Rastall's modified theory. We derive general analytical solutions considering a constant redshift function and a particular equation of state for energy density and pressure profiles. We show that because of the modification in the EM source of the field equations, there exist solutions respecting the WEC in the vicinity of the wormhole's throat for specified values of the parameters. Some particular solutions are discussed in detail.

We convert the squeezing of the two linear polarization modes into quadrature entanglement and show how to find out the best entanglement generated in a two-mode system using the inseparability criterion for continuous variable [Duan et al., Phys. Rev. Lett. 84, 2722 (2000)]. We verify this method experimentally with a direct measurement of the inseparability using two homodyne detections. We then map this entanglement into a polarization basis and achieve polarization entanglement.

We use the economically-ideal F re-Primont index which allows for multi-temporal/lateral comparisons. To compare the technology gap change between six types of farming, we provide the first extension of the F re-Primont index to the meta-frontier framework. Results indicate that all types of farming farms had TFP progress. Beef farms had the highest increase in TFP change and efficiency change. The metafrontier analysis indicates that field crop farms technology was the most productive. Acknowledgement :

description: The comoving mass density of massive black hole (MBH) remnants from pre-galactic star formation could have been similar in magnitude to the mass-density of supermassive black holes (SMBHs) in the present-day universe. We show that the fraction of MBHs that coalesce during the assembly of SMBHs can be extracted from the rate of ring-down gravitational waves that are detectable by Advanced LIGO. Based on the SMBH formation history inferred from the evolution of the quasar luminosity function, we show that an observed event rate of 1 per year will constrain the SMBH mass fraction that was contributed by MBHs coalescence down to a level of ~10^-6 for 20 solar mass MBH remnants (or ~10^-4 for 260 solar mass remnants).

description: The melting curve of pure silica (SiO$_2$) was determined using {\it ab initio} density functional theory together with the solid-liquid coexisting approach, thermodynamic integration and the Z method. The melting curves are consistent with a smooth slow increase in a large region from 50 GPa (dT/dP $\approx$ 15 K/GPa) to about 500 GPa (dT/dP $\approx$ 5 K/GPa) without any abrupt changes at around 120 GPa and 300 GPa as seen in some recent experimental and computational studies. The topography of the melting curve above 50 GPa is consistent with a gradual change in the distribution of the Si coordination numbers in the liquid state and the absence of large changes in the density following solid-solid phase transitions. The pair distribution functions show that the structural correlation in the liquid is mainly short-ranged and that the Si-O bond is stiff. The densification of the melt structure with pressure above 50 GPa is therefore due to an increase in 7- and 8-fold coordinated silicon.

description: The local, eigenfunction-weighted acoustic phonon density of states (DOS) tensor is calculated for a model substrate consisting of a semi-infinite isotropic elastic continuum with a stress-free surface. On the surface, the local DOS is proportional to the square of the frequency, as for the three-dimensional Debye model, but with a constant of proportionality that is considerably enhanced compared to the Debye value, a consequence of the Rayleigh surface modes. The local DOS tensor at the surface is also anisotropic, as expected. Inside the substrate the local DOS is both spatially anisotropic and non-quadratic in frequency. However, at large depths, the local DOS approaches the isotropic Debye value. The results are applied to a Si substrate.

description: This report examines the economic effects of the Export Enhancement Program (EEP) for poultry meat for 1987. Total exports have increased 79,000 metric tons due to the program. These numbers imply that every metric ton of poultry meat subsidized has resulted in an additional 0.83 metric ton of poultry meat exports at an average cost of $761 per metric ton. Considering that the average unit export value for all U.S. poultry exports was $1,038, the program has expanded poultry exports at relatively high cost. Although U.S. poultry exports have increased, other poultry exporters (including the EC) have not been significantly affected. U.S. producers have gained marginally, while U.S. consumers have lost an equivalent amount of welfare through higher domestic poultry prices. The primary beneficiaries have been consumers in the countries targeted for the EEP, primarily Iraq and Egypt. Additional analysis indicates that U.S. poultry production and exports probably would be somewhat higher if there were no EC policies affecting the world poultry and corn markets. Even with these policies in place, however, a slightly lower world price for poultry meat caused by these policies benefits U.S. consumers as much as it hurts U.S. producers. From the perspective of poultry markets, the effect of these EC policies on the United States is very small.

description: We derive the upper limit to the ejecta mass of S190814bv, a black hole-neutron star merger candidate, through the radiative transfer simulations for kilonovae with the realistic ejecta density profile as well as the detailed opacity and heating rate models. The limits to the ejecta mass strongly depend on the viewing angle. For the face-on observations ($\le45^\circ$), the total ejecta mass should be smaller than $0.1\,M_\odot$ for the average distance of S190814bv ($D=267$ Mpc), while larger mass is allowed for the edge-on observations. We also derive the conservative upper limits of the dynamical ejecta mass to be $0.02\,M_\odot$, $0.03\,M_\odot$, and $0.05\,M_\odot$ for the viewing angle $\le 20^\circ$, $\le 50^\circ$, and for $\le 90^\circ$, respectively. We show that the {\it iz}-band observation deeper than $22$ mag within 2 d after the GW trigger is crucial to detect the kilonova with the total ejecta mass of $0.06\,M_\odot$ at the distance of $D=300$ Mpc. We also show that a strong constraint on the NS mass-radius relation can be obtained if the future observations put the upper limit of $0.03\,M_\odot$ to the dynamical ejecta mass for a BH-NS event with the chirp mass smaller than $\lesssim 3\,M_\odot$ and effective spin larger than $\gtrsim 0.5$.

title: Autopia and The Truelist: Language Combined in Two Computer-Generated Books
Creators: name: Montfort, Nick
Publisher: name: Electronic Book Review
Year: 2021

description: Nick Montfort discusses two of his computer-generated texts that manifest as print-on-demand books, websites and gallery installations. Though distinct in form and content, Autopia and The Truelist were guided by the author's self-imposed constraints and programmed with minimal code to produce predetermined, "novel-size" outputs. Montfort intends theses texts to engage the imaginations of readers with the combinatory aspects of language in culture as well as invite them to a deeper reading of the generating code.

description: The analysis of biological fluids, such as blood and semen, discovered during the investigation of a potential crime can provide police forces with essential information to aid their investigation. However, many of the techniques for body fluid identification are not ideally suited to the analysis of potential evidence, being non-specific, destructive and expensive. Although individual presumptive tests are relatively inexpensive, the need to perform multiple tests on suspected biofluids can rapidly increase overall analysis costs. Furthermore, the use of presumptive tests typically involves the addition of test reagents to suspected biofluids, ultimately contaminating potential forensic evidence. The use of non-specific presumptive tests conducted at a crime scene often involve laboratory-based confirmatory tests, increasing the time taken for police to positively identify a suspected body fluid. Furthermore, there is currently no established method for estimating the age of a body fluid, thus police have no way of knowing if the sample is relevant to the investigation. [Continues.]

description: Strongly correlated systems containing d/f-electrons present a challenge to conventional density functional theory (DFT), such as the widely used local density approximation (LDA) or generalized gradient approximation (GGA). In this work, we developed a doubly screened Coulomb correction (DSCC) approach to perform on-site Coulomb interaction correction for strongly correlated materials. The on-site Coulomb interaction between localized d/f-electrons is determined from a model dielectric function that includes both the static dielectric and the Thomas-Fermi screening. All parameters of the dielectric model are efficiently obtained from self-consistent calculations. We applied DSCC to simulate the electronic and magnetic properties of typical 3d, 4f and 5f strongly correlated systems. The results show that the accuracy of DSCC is comparable to hybrid functionals, but an order of magnitude faster. In addition, DSCC can reflect the difference in the Coulomb interaction of the same element between metallic and insulating situations, similar to the popular but computationally expensive constrained random phase approximation (cRPA) approach. This feature suggests that DSCC is also a promising method for simulating Coulomb interaction parameters.

Counting Supertubes

description: The quantum states of the supertube are counted by directly quantizing the linearized Born-Infeld action near the round tube. The result is an entropy $S = 2π\sqrt{2 (Q_{D0}Q_{F1}-J)}$, in accord with conjectures in the literature. As a result, supertubes may be the generic D0-F1 bound state. Our approach also shows directly that supertubes are marginal bound states with a discrete spectrum. We also discuss the relation to recent suggestions of Mathur et al involving three-charge black holes.
