Subjects: Vinyl polymers -- Properties

description: Ethylene vinyl alcohol (EVOH) copolymers are widely used in food packaging for shelf stable foods because of their good oxygen barrier. However, EVOH is very sensitive to moisture which adversely affects its oxygen barrier. The overall objective of this research was to understand the influences of thermal processing on oxygen barrier properties of multilayer EVOH films, with emphasis on influence of water absorption by packaging films when exposed to conditions of high moisture and high temperature during processing. The research focused on two multilayer films containing EVOH as the oxygen barrier which were used as lidstock for rigid trays. Film A was a laminated structure of oriented polyethylene terephthalate (PET), EVOH and polypropylene (PP). Film B consisted of PET laminated to a co-extruded structure of PP/tie/Nylon 6/EVOH/Nylon 6/tie/PP. Oxygen transmission rates were measured on films after retort and combined microwave-hot water heating under conditions necessary to produce shelf-stable low acid foods. For both films, the retort treatments resulted in more deterioration of the oxygen barrier than microwave treatments. This was attributed to the amount of moisture absorbed during retort treatment, which was thought to be directly related to duration of direct exposure of films to high temperature humid environment during processing. Storage of packages for 2 months under ambient conditions resulted in recovery of more than 50% of the oxygen barrier. Further studies were carried out to investigate the relationship between the amount of water absorbed during retort processing and oxygen transmission through the films. Results confirmed dramatic increases in oxygen transmission at high film water contents which was attributed to plasticization and stresses created by high moisture and temperature conditions. Water absorption behavior of multilayer films was also studied at different temperatures and compared to monolayer films representing the individual components of the multilayer films. A preliminary study on use of split post dielectric resonator (SPDR) technique as a method for measuring amount of water in polymers was carried out. The measured dielectric property data correlated well with water absorption data, indicating that the method can be used to rapidly and non-destructively measure water absorption in these films.

description: In this paper we explore the following question: can the probabilities constituting the quantum Boltzmann distribution, $P^B_n \propto e^{-E_n/kT}$, be derived from a requirement that the quantum configuration-space distribution for a system in thermal equilibrium be very similar to the corresponding classical distribution? It is certainly to be expected that the quantum distribution in configuration space will approach the classical distribution as the temperature approaches infinity, and a well-known equation derived from the Boltzmann distribution shows that this is generically the case. Here we ask whether one can reason in the opposite direction, that is, from quantum-classical agreement to the Boltzmann probabilities. For two of the simple examples we consider---a particle in a one-dimensional box and a simple harmonic oscillator---this approach leads to probability distributions that provably approach the Boltzmann probabilities at high temperature, in the sense that the Kullback-Leibler divergence between the distributions approaches zero.

description: This paper proposes an optimal control problem for a parabolic equation with a nonlocal nonlinearity. The system is described by a parabolic equation involving a nonlinear term that depends on the solution and its integral over the domain. We prove the existence and uniqueness of the solution to the system and the boundedness of the solution. Regularity results for the control-to-state operator, the cost functional and the adjoint state are also proved. We show the existence of optimal solutions and derive first-order necessary optimality conditions. In addition, second-order necessary and sufficient conditions for optimality are established.

description: We have conducted a survey of Ultra-luminous Infrared Galaxies (ULIRGs) with the Infrared Spectrograph on the Spitzer Space Telescope, obtaining spectra from 5.0-38.5um for 77 sources with 0.022Jy. The average warm molecular gas mass is ~2x10^8solar-masses. High extinction, inferred from the 9.7um silicate absorption depth, is not observed along the line of site to the molecular gas. The derived H2 mass does not depend on F(25um)/F(60um), which has been used to infer either starburst or AGN dominance. Similarly, the molecular mass does not scale with the 25 or 60um luminosities. In general, the H2 emission is consistent with an origin in photo-dissociation regions associated with star formation. We detect the S(0) 28.22um emission line in a few ULIRGs. Including this line in the model fits tends to lower the temperature by ~50-100K, resulting in a significant increase in the gas mass. The presence of a cooler component cannot be ruled out in the remainder of our sample, for which we do not detect the S(0) line. The measured S(7) 5.51um line fluxes in six ULIRGs implies ~3x10^6 solar-masses of hot (~1400K) H2. The warm gas mass is typically less than 1% of the cold gas mass derived from CO observations.

description: Poverty alleviation through employment promotion is to promote the poor households to get rid of poverty through promoting employment to increase income. It is the most effective and direct way out of poverty. Dongchuan District, located in the alpine valley area of northeastern Yunnan, is a typical extreme poverty-stricken county in China. Under its jurisdiction, Awang Town is a mountainous township with a wide area of poverty and an extreme poverty. The incidence of poverty in 2015 reached 35.39%. In recent years, through the implementation of various policies to combat poverty, combined with the advantages as a traditional “hometown of migrant labor”, focusing on employment-promoting poverty alleviation work, Awang Town has made certain achievements in poverty alleviation work. By the end of 2018, the poverty rate in the town fell to 0.57%, marking a major victory in the town’s fight against poverty. Through field investigations, this article summarizes the main practices of Awang Town to carry out employment-promoting targeted poverty alleviation, analyzes the poverty alleviation achievements and successful experience of the town’s employment-promoting targeted poverty alleviation work and discusses the promotion and application of this model so as to provide reference Yunnan Province and other poverty-stricken areas to carry out employment-promoting poverty alleviation.

Empirical analysis of used construction equipment and auction house revenues
Creators: name: Ponnaluru, Srinivasa Sasdhar
Publisher: name: Washington State University
Year: 2009
Subjects: Excavating machinery

description: This dissertation consists of three separate papers (as Chapters 1, 2 and 3). The first chapter deals with a spatial hedonic price analysis of used excavators. Chapter 2 deals with empirical estimation of functions for auction house revenue. Chapter 3 deals with empirical analysis of price relationships in a multi-item, multi-type auction. The objective of the first paper is to specify and estimate a spatial hedonic price function for used excavators sold by auction in North America from 1996 to 2005. The results indicate that prices of used excavators differ significantly for various reasons. Not surprisingly, prices vary by region of sale, physical condition, and brand of the equipment. We also find that prices are different between auction houses themselves. Furthermore, there exist 'within sale' spatial effects on the selling price that are statistically significant. Auction houses, besides providing auctioneering service to sellers and bidders, can influence selling prices in the auctions for used construction equipment. The objective of the second paper is to quantify the effects of multiple units of items and to identify the influence of different types of items on auction revenue. The results indicate that auction revenues increase with an increasing rate for some items (graders) and with a decreasing rate for others (excavators and wheel loaders). Magnitude of effects varies from auction house to auction house, which, might be due to heterogeneity in the groups of bidders across auction houses. Cross quantity spillover effects also vary in magnitude and direction from auction house to auction house. Auction houses stage events where sellers offer for sale multiple units of an item, items of different types, and items in various physical conditions. Objective of the third paper is to specify and estimate theoretically consistent inverse supply functions for multi-unit and multi-type auctions. It is hypothesized that price complementarities exist between different items being offered at an event, offering opportunity for auction houses to exploit price relationships by preselecting the number, type and condition of equipment. Normalized quadratic inverse supply functions are estimated for different types of equipment, and hypothesis are tested using transaction level, time series cross section data on equipment sales from 1996 to 2006.

We analyze the accretion process when different test fluids are falling onto these regular black holes. The accreting fluid is being classified through equation of state according to features of regular black holes. The behavior of fluid flow and the existence of sonic points is being checked for these regular black holes. It is noted that three velocity depends on critical points and equation of state parameter on phase space.

description: Polarons and spin-orbit (SO) coupling are distinct quantum effects that play a critical role in charge transport and spin-orbitronics. Polarons originate from strong electron-phonon interaction and are ubiquitous in polarizable materials featuring electron localization, in particular $\mathrm{3d}$ transition metal oxides (TMOs). On the other hand, the relativistic coupling between the spin and orbital angular momentum is notable in lattices with heavy atoms and develops in $\mathrm{5d}$ TMOs, where electrons are spatially delocalized. Here we combine ab initio calculations and magnetic measurements to show that these two seemingly mutually exclusive interactions are entangled in the electron-doped SO-coupled Mott insulator $\mathrm{Ba_2Na_{1-x}Ca_xOsO_6}$ ($0< x < 1$), unveiling the formation of spin-orbital bipolarons. Polaron charge trapping, favoured by the Jahn-Teller lattice activity, converts the Os $\mathrm{5d^1}$ spin-orbital $\mathrm{J_{eff}=3/2}$ levels, characteristic of the parent compound $\mathrm{Ba_2NaOsO_6}$ (BNOO), into a bipolaron $\mathrm{5d^2}$ $\mathrm{J_{eff}=2}$ manifold, leading to the coexistence of different J-effective states in a single-phase material. The gradual increase of bipolarons with increasing doping creates robust in-gap states that prevents the transition to a metal phase even at ultrahigh doping, thus preserving the Mott gap across the entire doping range from $\mathrm{d^1}$ BNOO to $\mathrm{d^2}$ $\mathrm{Ba_2CaOsO_6}$ (BCOO).

description: The purpose of this study was to record the process, events, and reactions that occurred when an administrator made purposeful changes to the culture of a toxic alternative high school. Consistent with the purpose, this study used qualitative case study design and methods. The principles of action research were also applied, because the researcher was also a participant. Participants' journals were the primary data sources for this study. An alternative high school in a rural Washington state community was the site for this study. The journal data were analyzed and compiled to create a portrait of the cultural change process in the school during the period of one academic year. In this study, a narrative regarding cultural system changes and their impact was developed. The responses in the journals of the other participants were analyzed for descriptions of what did happen and their perceptions of the changes. The data were analyzed and sorted into themes from which a narrative was constructed. An attempt was made in the narrative to include the various voices of the participants in the writing. The elements that contribute to a toxic school culture were explored. A case study was conducted to record the experiences of the individuals involved with the school as the administrator made purposeful cultural changes to the school in order to create a positive school culture. Several conclusions were reached as a result of this study: (a) Chronological order of the changes made does matter; (b) it is not necessary to "gut" the staff of a building to retool the culture; (c) staff is more resistant to change than students; (d) a positive school culture increases emotional safety, student connectedness, and impacts student learning; (e) in a healthy culture you do not want to be complacent. This study is significant in that it contributes knowledge regarding the process of purposeful cultural change at alternative high schools. Conclusions and implications resulting from this study may be useful to administrators at alternative high schools as they endeavor to retool a toxic school culture into a positive school culture.

description: FixMyStreet (FMS) is a web-based civic participation platform that allows inhabitants to report environmental defects like potholes and damaged pavements to the government. In this paper, we examine the use of FMS in Brussels, the capital city of Belgium. Analyzing a total of 30,041 reports since its inception in 2013, we demonstrate how civic participation on FMS varies between the ethnically diverse districts in Brussels. We compare FMS use to a range of sociodemographic indicators derived from official city statistics as well as geotagged social media data from Twitter. Our statistical analysis revealed several significant differences between the districts that suggested that crowdsourced civic participation platforms tend to marginalize low-income and ethnically diverse communities. In this respect, our findings provide timely evidence to inform the design of more inclusive crowdsourced, civic participation platforms in the future.

By incorporating the anharmonic perturbation into the WKB energy splitting formula we show that the WKB approximation can be greatly improved in the region over which the tunneling is appreciable. We also observe that the usual WKB results can be obtained from our formalism as a limiting case in which the two potential minima are far apart.

description: We generalize the Hamiltonian picture of General Relativity coupled to classical matter, known as geometrodynamics, to the case where such matter is described by a Quantum Field Theory in Curved Spacetime, but gravity is still described by a classical metric tensor field over a spatial hypersurface and its associated momentum. Thus, in our approach there is no non-dynamic background structure, apart from the manifold of events, and the gravitational and quantum degrees of freedom have their dynamics inextricably coupled. Given the Hamiltonian natureof the framework, we work with the generators of hypersurface deformations over the manifold of quantum states. The construction relies heavily on the differential geometry of a fibration of the set of quantum states over the set of gravitational variables. An important feature of this work is the use of Gaussian measures over the space of matter fields and of Hida distributions to define a common superspace to all possible Hilbert spaces with different measures, to properly characterize the Schrodinger wave functional picture of QFT in curved spacetime. This allows us to relate states within different Hilbert spaces in the case of vacuum states or measures that depend on the gravitational degrees of freedom, as the ones associated to Ashtekar's complex structure. This is achieved through the inclusion of a quantum Hermitian connection for the fibration, which will have profound physical implications. The most remarkable physical features of the construction are norm conservation of the quantum state (even if the total dynamics are non-unitary), the clear identification of the hybrid conserved quantities and the description of a dynamical backreaction of quantum matter on geometry and vice versa, which shall modify the physical properties the gravitational field would have in the absence of backreaction.

description: Foraging societies with low population densities would seem an unlikely context in which to find extensive, continental scale, exchange systems featuring formal and standardized methods and materials of interaction. Yet, in the Late Archaic of the North American Midcontinent, this situation unfolds. How does formalized exchange function in such dispersed, small scale foraging societies? How does it help to create larger social entities and increasing sociopolitical complexity? How do such systems develop, what do they do, and why? In this study, a synthesis of anthropological theory on exchange and evolutionary theory of cooperative behavior is developed to produce a model of exchange with several testable predictions. These predictions include that differential access to exchange benefits will exist within and between communities, that exchange is inherently risky to participants and their communities, the frequency and scale of exchange will increase as trust is established and validated, exchange of material goods creates opportunities and incentives for social change, and conflict between communities is expected when trust is lost or undermined. These are then examined through a methodologically diverse set of studies involving analysis of lithic and copper artifacts to examine changes affecting Late Archaic societies in the western Great Lakes between 4000 and 2000 years ago. Data from the Late Archaic Riverside site, Middle Archaic Reigh site, and sites of the Late Archaic Burnt Rollways phase are examined to understand the production and movement of copper and lithic exchange materials, access to and benefits from exchange networks, and social changes accompanying the development of such systems of interaction. This study demonstrates that the Burnt Rollways phase is socially distinct from, and not interacting with, their downstream neighbors at Reigh and Riverside, while Riverside is engaged in a formal system of interaction and ritual with communities as distant as the lower Ohio River valley. As a consequence of this interaction network, Riverside exhibits differential access to benefits, standardization and ritualization of materials of interaction including formalized bifaces of Wyandotte chert and copper beads, intensification of exchange through time, significant social changes emphasizing the growing importance of women and children, and conflict.

description: The identification of distinct charge transport features, deriving from nontrivial bulk band and surface states, has been a challenging subject in the field of topological systems. In topological Dirac and Weyl semimetals, nontrivial conical bands with Fermi-arc surface states give rise to negative longitudinal magnetoresistance due to chiral anomaly effect and unusual thickness dependent quantum oscillation from Weyl-orbit effect, which were demonstrated recently in experiments. In this work, we report the experimental observations of large nonlinear and nonreciprocal transport effects for both longitudinal and transverse channels in an untwinned Weyl metal of SrRuO$_3$ thin film grown on a SrTiO$_{3}$ substrate. From rigorous measurements with bias current applied along various directions with respect to the crystalline principal axes, the magnitude of nonlinear Hall signals from the transverse channel exhibits a simple sin$α$ dependence at low temperatures, where $α$ is the angle between bias current direction and orthorhombic [001]$_{\rm o}$, reaching a maximum when current is along orthorhombic [1-10]$_{\rm o}$. On the contrary, the magnitude of nonlinear and nonreciprocal signals in the longitudinal channel attains a maximum for bias current along [001]$_{\rm o}$, and it vanishes for bias current along [1-10]$_{\rm o}$. The observed $α$-dependent nonlinear and nonreciprocal signals in longitudinal and transverse channels reveal a magnetic Weyl phase with an effective Berry curvature dipole along [1-10]$_{\rm o}$ from surface states, accompanied by 1D chiral edge modes along [001]$_{\rm o}$.

Solving the Cosmological Constant Problem with 5D Time-Field Theory

Publisher: name: Zenodo

description: This presentation explores how the 5D Time-Field Theory provides a natural solution to the cosmological constant problem. Instead of requiring fine-tuning, the theory introduces an extra time-like dimension (T2T_2T2) that dynamically regulates Λ\LambdaΛ, explaining why it is small but nonzero. The model predicts an emergent dark energy effect and may offer insights into the expansion of the universe without invoking a fixed cosmological constant.

description: Finite type nilpotent spaces are weakly equivalent if and only if their singular cochains are quasi-isomorphic as E-infinity algebras. The cochain functor from the homotopy category of finite type nilpotent spaces to the homotopy category of E-infinity algebras is faithful but not full.

description: We have studied the existence of self-dual effective compact and true compacton configurations in Abelian Higgs models with generalized dynamics. We have named of an effective compact solution the one whose profile behavior is very similar to the one of a compacton structure but still preserves a tail in its asymptotic decay. In particular we have investigate the electrically neutral configurations of the Maxwell-Higgs and Born-Infeld-Higgs models and the electrically charged ones of the Chern-Simons-Higgs and Maxwell-Chern-Simons-Higgs models. The generalization of the kinetic terms is performed by means of dielectric functions in gauge and Higgs sectors. The implementation of the BPS formalism without the need to use a specific \textit{Ansatz} has leaded us to the explicit determination of the dielectric function associated to the Higgs sector to be proportional to $λ|ϕ|^{2λ-2}$, $λ>1$. Consequently, the followed procedure allows us to determine explicitly new families of self-dual potentials for every model. We have also observed that for sufficiently large values of $λ$ every model supports effective compact vortices. The true compacton solutions arising for $λ= \infty $ are analytical. Therefore, this new self-dual structures enhance the space of BPS solutions of the Abelian Higgs models and they probably will imply in interesting applications in physics and mathematics.

description: In this paper we establish a connection between the bulk topological structure and the magnetic properties of drumhead surface states of nodal loop semimetals. We identify the magnetic characteristics of the surface states and compute the system's magnon spectrum by treating electron-electron interactions on a mean-field level. We draw attention to a subtle connection between a Lifshitz-like transition of the surface states driven by mechanical distortions and the magnetic characteristics of the system. Our findings may be experimentally verified e.g. by spin polarized electron energy loss spectroscopy of nodal semimetal surfaces.

Subjects: Teachers -- Professional relationships

description: This phenomenological, qualitative study explored the lived experiences of ten teacher leaders in K-12 schools who have served in non-supervisory teacher leader roles, including as "mentors" or "instructional coaches." Data were collected through a seriesof open-ended interviews with each participant. The study utilizes portraiture and auto-ethnography and a cross-case analysis. This technique reveals the multiple roles employed by full time teacher leader in K-12 school settings, underscoring their backgrounds and motivations, the nature of their work as teacher leaders, and how they make sense of their work. In addition, the study explores teachers' experiences when they exit these roles

description: We present a summary of our recent publication concerning the derivation of the extended Casimir-Polder dispersive interaction between two neutrons. Dynamical polarizations of the neutrons, recently derived within Chiral Effective Theory are used for the purpose. An account of the higher frequency/energy behavior of these entities related to the opening of one-pion production channel and the excitation of the $Δ$ resonance are taken into consideration in our derivation of the CP interaction. The neutron-neutron system in free space is treated in details so are the neutron-wall and the wall-neutron-wall systems. The case of tetraneutron (a 4 neutron system) in a resonant state is then briefly considered. The 4n CP interaction is evaluated to assess its potential relevance to the ongoing debate concerning the nature of the tetraneutron.

description: The exactly solvable eigenproblems in Schrödinger quantum mechanics typically involve the differential "shift operators". In the standard supersymmetric (SUSY) case, the shift operator turns out to be of first order. In this work, I discuss a technique to generate exactly solvable eigenproblems by using second order shift operators. The links between this method and SUSY are analysed. As an example, we show the existence of a two-parametric family of exactly solvable Hamiltonians, which contains the Abraham-Moses potentials as a particular case.

description: Rural areas in the developing countries are predominantly devoid of Internet access as it is not viable for operators to provide broadband service in these areas. To solve this problem, we propose a middle mile Long erm Evolution Advanced (LTE-A) network operating in TV white space to connect villages to an optical Point of Presence (PoP) located in the vicinity of a rural area. We study the problem of spectrum sharing for the middle mile networks deployed by multiple operators. A graph theory based Fairness Constrained Channel Allocation (FCCA) algorithm is proposed, employing Carrier Aggregation (CA) and Listen Before Talk (LBT) features of LTE-A. We perform extensive system level simulations to demonstrate that FCCA not only increases spectral efficiency but also improves system fairness.
