description: Nickel and chromium as alloying elements in steel have shown to increase corrosion resistivity in high temperature environments and molybdenum is known to provide material pitting resistivity. In sulphur rich environment, the protective mechanism of the alloying elements varies. Molybdenum is known to adsorb the sulphur, while chromium and nickel have antagonistic effects in the presence of sulphur. In the present work, several steel coupons of different alloy types were exposed in different geothermal setting for 3 months. The corrosion rate during exposure was evaluated using weight loss measurements and microstructural analysis. The results show that non-alloyed steel had by far the highest material loss. Furthermore, the corrosion products formed are iron sulphate products. The findings indicate a linear correlation of lower corrosion rate in high sulphur environment to the proportionality of nickel in the alloy.

description: There is a significant clinical need for engineered bone graft substitutes that can quickly, effectively, and safely repair segmental bone defects. One emerging field of interest involves the growth of engineered bone tissue in vitro within bioreactors, the most promising of which, are perfusion bioreactors. Utilizing a tubular perfusion system bioreactor, which allows media to perfuse freely around alginate scaffolds laden with human mesenchymal stem cells, large-scale bone constructs can be created by simply aggregating these beads together in the desired shape. However, these engineered constructs lack inherent vasculature and quickly develop a necrotic core, where no nutrient exchange occurs. Through the use of 3D printed vascular structures, used in conjunction with a TPS bioreactor, cell viability after just one day of aggregation was found to increase by as much as 50 percent in the core of these constructs, with in silico modeling predicting construct viability at steady state.

description: Along with COVID-19 pandemic we are also fighting an `infodemic'. Fake news and rumors are rampant on social media. Believing in rumors can cause significant harm. This is further exacerbated at the time of a pandemic. To tackle this, we curate and release a manually annotated dataset of 10,700 social media posts and articles of real and fake news on COVID-19. We benchmark the annotated dataset with four machine learning baselines - Decision Tree, Logistic Regression, Gradient Boost, and Support Vector Machine (SVM). We obtain the best performance of 93.46% F1-score with SVM. The data and code is available at: https://github.com/parthpatwa/covid19-fake-news-dectection

description: We discuss the equilibrium condition for a liquid that partially wets a solid on the level of intermolecular forces. Using a mean field continuum description, we generalize the capillary pressure from variation of the free energy and show at what length scale the equilibrium contact angle is selected. After recovering Young's law for homogeneous substrates, it is shown how hysteresis of the contact angle can be incorporated in a self-consistent fashion. In all cases the liquid-vapor interface takes a nontrivial shape, which is compared to models using a disjoining pressure.

description: In this work we discuss the process of measurements by a detector in an uniformly accelerated rectilinear motion, interacting linearly with a massive scalar field. The detector model for field quanta is a point-like system with a ground state and a continuum of unbounded states. We employ the Glauber theory of photodetection. In an uniformly accelerated reference frame, the detector, interacting with the field prepared in an arbitrary state of the Rindler Fock space, is excited only by absorption processes. For the uniformly accelerated detector prepared in the ground state, we evaluate the transition probability rate in three important situations. In the first one the field is prepared in an arbitrary state of $n$-Rindler quanta, then we consider a thermal Rindler state at a given temperature $β^{-1}$, and finally the case in which the state of the field is taken to be the Minkowski vacuum. The well-known result that the latter excitation rates are equal is recovered. Accelerated or inertial observer interpretations of the measurements performed by the accelerated detector is presented. Finally, we investigate the behaviour of the detector in a frame which is inertial in the remote past but in the far future becomes uniformly accelerated. For the massless case, we obtain that the transition probability rate of the detector in the far future is tantamount to the analogous quantity for the detector at rest in a non-inertial reference frame interacting with the field prepared in an usual thermal state.

description: The possibility of reconstructing the whole history of the scale factor of the Universe from the power spectrum of relic gravitational waves (RGWs) makes the study of these waves quite interesting. First, we explore the impact of a hypothetical era -right after reheating- dominated by mini black holes and radiation that may lower the spectrum several orders of magnitude. Next, we calculate the power spectrum of the RGWs taking into account the present stage of accelerated expansion and an hypothetical second dust era. Finally, we study the generalized second law of gravitational thermodynamics applied to the present era of accelerated expansion of the Universe.

description: The quantum logic gates used in the design of a quantum computer should be both universal, meaning arbitrary quantum computations can be performed, and fault-tolerant, meaning the gates keep errors from cascading out of control. A number of no-go theorems constrain the ways in which a set of fault-tolerant logic gates can be universal. These theorems are very restrictive, and conventional wisdom holds that a universal fault-tolerant logic gate set cannot be implemented natively, requiring us to use costly distillation procedures for quantum computation. Here, we present a general framework for universal fault-tolerant logic with stabiliser codes, together with a no-go theorem that reveals the very broad conditions constraining such gate sets. Our theorem applies to a wide range of stabiliser code families, including concatenated codes and conventional topological stabiliser codes such as the surface code. The broad applicability of our no-go theorem provides a new perspective on how the constraints on universal fault-tolerant gate sets can be overcome. In particular, we show how non-unitary implementations of logic gates provide a general approach to circumvent the no-go theorem, and we present a rich landscape of constructions for logic gate sets that are both universal and fault-tolerant. That is, rather than restricting what is possible, our no-go theorem provides a signpost to guide us to new, efficient architectures for fault-tolerant quantum computing.

description: Design of machine foundations that are subject to dynamic loading require

that their amplified displacement is within certain limit so that such displacement

doesn’t impede the operation of the machine they are supporting. For the design of

such foundations, several methods are available that are based on a mathematical

solution of the differential equation that represents dynamic loads on an elastic half

space. When the soil conditions are not uniform, the response cannot be predicted

accurately by these methods and hence numerical methods should be used to analyze

the problem. This research presents a numerical solution to a foundation subject to

dynamic loading considering: 1) the effect of soil layering on the dynamic response.

Specifically, a footing rests on a finite soil layer over an elastic half space and 2) the

effect of the depth of embedment of a foundation in a homogenous elastic half space

on its dynamic response

ETYMOLOGY: Named in honor of the Warren Halley family on whose ranch most of our prospecting was done.
HOLOTYPE: AMNH 77367, a lower molar.
TYPE LOCALITY: Clambank Hollow, Chouteau County, Montana.
KNOWN DISTRIBUTION: Judith River Formation, Montana.
DIAGNOSIS: Smaller than Alphadon praesagus but larger than A. lulli from the Lance Formation. Upper molars with stylar cusp D well developed and larger than stylar cusp C; metaconule and protoconule distinct, protocone low.
DESCRIPTION: Several lower molars from Clambank Hollow show morphological differences from teeth that can be assigned to A. praesagus. AMNH 77367 is significantly smaller (length 2.1 mm., fig. 13U, V) than lower molars of A. praesagus. Its paraconid is a conical cusp and it is slightly medial to the metaconid. The metaconid is anteroposteriorly elongated, particularly at its base, and tapers toward the apex. The protoconid is taller than the metaconid and situated anterior to it. The talonid is deep and basined and the crista obliqua is oriented in the manner characteristic of Alphadon. The hypoconid is a well-developed cusp, and the hypoconulid is directed posteriorly and more separated from the entoconid than in most contemporary marsupials. The width of the talonid (1.2 mm.) is equal to that of the trigonid.
A partial upper molar, AMNH 77370, is small enough to be included within A. halleyi (fig. 13W). The width of the crown is 1.7 mm. and it is approximately equal to the estimated length. The stylar shelf anterior to stylar cusp C is broken. Stylar cusp D is well developed and larger than stylar cusp C. The metacone is as high as the paracone and separated from it by a narrow valley. Both conules are present, and the protocone is a low cusp. Alphadon halleyi is a possible ancestor to the Maestrichtian A. lulli.

description: Using the field-particle correlation technique, we examine the particle energization in a 1D-2V continuum Vlasov--Maxwell simulation of a perpendicular magnetized collisionless shock. The combination of the field-particle correlation technique with the high fidelity representation of the particle distribution function provided by a direct discretization of the Vlasov equation allows us to ascertain the details of the exchange of energy between the electromagnetic fields and the particles in phase space. We identify the velocity-space signatures of shock-drift acceleration of the ions and adiabatic heating of the electrons due to the perpendicular collisionless shock by constructing a simplified model with the minimum ingredients necessary to produce the observed energization signatures in the self-consistent Vlasov-Maxwell simulation. We are thus able to completely characterize the energy transfer in the perpendicular collisionless shock considered here and provide predictions for the application of the field-particle correlation technique to spacecraft measurements of collisionless shocks.

Es ist mitunter seinen engen freundschaftlichen Beziehungen zu verdanken, dass bekannte Musiker wie Johannes Brahms, Joseph Joachim und Clara Schumann in der Westfalenstadt auftraten. In Anbetracht seiner zahlreichen Konzertverpflichtungen ist sein kompositorisches Œuvre vergleichsweise schmal. 1889 widmete sich Grimm der Bearbeitung von frühen Klavierkompositionen, darunter die Orchesterfassung seines Scherzos op. 5 Nr. 2, welche jedoch unveröffentlicht blieb.

description: Large future galaxy cluster surveys, combined with cosmic microwave background observations, can achieve a high sensitivity to the masses of cosmologically important neutrinos. We show that a weak lensing selected sample of ~100,000 clusters could tighten the current upper bound on the sum of masses of neutrino species by an order of magnitude, to a level of 0.03 eV. Since this statistical sensitivity is below the best existing lower limit on the mass of at least one neutrino species, a future detection is likely, provided that systematic errors can be controlled to a similar level.

description: In this paper, we first try to shed light on the ambiguities that exist in the literature in the generalization of the standard linear response theory (LRT) which has been basically formulated for closed systems to the theory of open quantum systems in the Heisenberg picture. Then, we investigate the linear response of a driven-dissipative optomechanical system (OMS) to a weak time-dependent perturbation using the so-called generalized LRT. It is shown how the Green's function equations of motion of a standard OMS as an open quantum system can be obtained from the quantum Langevin equations (QLEs) in the Heisenberg picture. The obtained results explain a wealth of phenomena, including the anti-resonance, normal mode splitting and the optomechanically induced transparency (OMIT). Furthermore, the reason why the Stokes or anti-Stokes sidebands are amplified or attenuated in the red or blue detuning regimes is clearly explained which is in exact coincidence, especially in the weak-coupling regime, with the Raman-scattering picture.

description: This paper reviews some of the recent major research findings concerning the effect of household behavior on food consumption and nutrition. Important extensions to the understanding of household behavior have been made in the areas of the impact of income and price changes, agricultural households, the effects of agricultural commercialization, the new household economics, and particularly the effect of time as a scarce economic resource, the intrahousehold allocation of food, and the determinants of nutritional status. This knowledge is important because the response by households determines the ultimate impact of economic changes and government actions on the nutritional status of the population.

description: A framework was developed in order to specify a model for annual U.S. per capita consumption of cigarettes. Three separate time related variables were utilized to measure the effects of health related information regarding smoking. The empirical results from the post World War II data set reveal that while prices and income are important determinants of cigarette consumption, the estimates for both were in the inelastic range. The age distribution of the adult population is also an important variable. While the development of the filter tip has been successful in stimulating smoking, the low tar and nicotine innovation has not had a statistically significant effect. Health information has repeatedly produced substantial short and long run effects. Current consumption is falling at an annual rate of between 3 to 4 percent.

description: A rather general enhancement of superconductivity is demonstrated in a hybrid structure consisting of submicron superconducting (SC) sample combined with an in-plane ferromagnet (FM). The superconducting state resists much higher applied magnetic fields for both perpendicular polarities, as applied field is screened by the FM. In addition, FM induces (in the perpendicular direction to its moment) two opposite current-flows in the SC plane, under and aside the magnet, respectively. Due to the compensation effects, superconductivity persists up to higher applied currents. With increasing current, the sample undergoes SC-"resistive"-normal state transitions through a mixture of vortex-antivortex and phase-slip phenomena.

description: We investigated the phase separation of dioleoylphosphatidylserine (DOPS) and dipalmitoylphosphatidylcholine (DPPC) in giant unilamellar vesicles in hypotonic solution using fluorescence and confocal laser scanning microscopy. Although phase separation in charged lipid membranes is generally suppressed by the electrostatic repulsion between the charged headgroups, osmotic stress can promote the formation of charged lipid domains. Interestingly, we observed three-phase coexistence even in DOPS/DPPC binary lipid mixtures. The three phases were DPPC-rich, dissociated DOPS-rich, and nondissociated DOPS-rich phases. The two forms of DOPS were found to coexist owing to the ionization of the DOPS headgroup, such that the system could be regarded as quasi-ternary. The three formed phases with differently ionized DOPS domains were successfully identified experimentally by monitoring the adsorption of positively charged particles. In addition, coarse-grained molecular dynamics simulations confirmed the stability of the three-phase coexistence. Attraction mediated by hydrogen bonding between protonated DOPS molecules and reduction of the electrostatic interactions at the domain boundaries stabilized the three-phase coexistence.

description: Published data for large amplitude asymptotic giant branch variables in the Large Magellanic Cloud are re-analysed to establish the constants for an infrared (K) period-luminosity relation of the form: Mk=rho[log P-2.38] + delta. A slope of rho=-3.51+/-0.20 and a zero point of delta=-7.15+/-0.06 are found for oxygen-rich Miras (if a distance modulus of 18.39+/-0.05 is used for the LMC). Assuming this slope is applicable to Galactic Miras we discuss the zero-point for these stars using the revised Hipparcos parallaxes together with published VLBI parallaxes for OH Masers and Miras in Globular Clusters. These result in a mean zero-point of delta=-7.25+/-0.07 for O-rich Galactic Miras. The zero-point for Miras in the Galactic Bulge is not significantly different from this value. Carbon-rich stars are also discussed and provide results that are consistent with the above numbers, but with higher uncertainties. Within the uncertainties there is no evidence for a significant difference between the period-luminosity relation zero-points for systems with different metallicity.

description: Assessment is a key element in the teaching–learning process in physical education (PE). In 2020, the Association Internationale des Écoles Supérieures d’Éducation Physique (AIESEP) published a position statement on PE assessment, in which it reviews the current state of the field and establishes the current yet forward-looking main lines of research on this topic. The most widely used approach, which this article reviews in depth, is assessment for learning (AfL). In Spain, the most widespread approach employed in PE throughout primary and secondary education in the last 25 years has been formative and shared assessment, which clearly aligns with the AIESEP position statement. The objective of this study was to gain an understanding of the main contributions of the formative and shared assessment model in PE and PE teacher education (PETE). Four databases (ERIC, SCOPUS, WOS and DIALNET) were explored, and 51 documents were selected on which an inductive thematic analysis was conducted. The evidence obtained at different educational levels and contexts seems to show a positive influence of formative and shared assessment on learning outcomes, which has favoured the expansion of the model, especially in PETE. Research on the transfer of PETE to educational practice has indicated that adequate continuing professional development seems necessary to help teachers integrate formative and shared assessment in their PE classroom. In conclusion, this model can provide an answer to some of the current questions being raised at an international level about PE assessment, especially in relation to students’ involvement in the assessment process and its role in PETE.

Evidence of noncompetitive pricing either through price discrimination across destinations or through imperfect exchange rate pass-through is found in this small but growing segment of the international rice trade.

description: Farmer perceptions of extension program delivery methods and an analysis of the relationships of method and farmer characteristics to evaluation scores are presented. Evaluation scores tend to increase with written, interactive and variable-scheduled methods and methods where users determine the agenda. Evaluations tend to be lower for high user cost and "high-tech" methods. Substantial similarity of results exists across groups of farmers differing by age, education levels, farm size and farm type. There are differences, however, in absolute valuation of the method characteristics across the groups.
The enhanced Rate Proportional Differentiation Model for the future Internet differentiated services
Creators: name: Shi, Xizheng
Publisher: name: University of British Columbia
Year: 2009

description: With the advent of diversified network applications and utilization, the services demanded by users demonstrate divergent requirements. However, the traditional network service model, which provides all the users with the same performance level (best effort service), cannot meet the demand for providing a set of differentiated services. A number of service models, especially the Integrated Service model and the Differentiated Service model, have been proposed to address this problem. This thesis focuses on a new differentiated service model, called the Rate Proportional Differentiation (RPD) Services model. We propose an improvement of the model that can accommodate different differentiation requirements of the responsive and non-responsive traffic. We investigate a number of implementation issues of the service model using the network simulator NS- 2, including the problems of traffic starvation and fairness within each service class.

description: We study here the gravitational collapse of a matter cloud with a non-vanishing tangential pressure in the presence of a non-zero cosmological term. Conditions for bounce and singularity formation are derived for the model. It is also shown that when the tangential pressures vanish, the bounce and singularity conditions reduce to that of the dust case studied earlier. The collapsing interior is matched with an exterior which is asymptotically de Sitter or anti de Sitter, depending on the sign of cosmological constant. The junction conditions for matching the cloud to exterior are specified. The effect of the cosmological term on apparent horizons is studied in some detail, and the nature of central singularity is analyzed. We also discuss here the visibility of the singularity and implications for the cosmic censorship conjecture.

description: This study determines the likely effect of cost-share incentives on participation in the Tennessee Forest Stewardship Program and identifies other factors that may contribute to participation. A random utility model is used to determine the probability that a landowner will choose to participate in the program. A binary choice model is specified to represent the dichotomous decision and a logit procedure is used to fit the model. Data are obtained from mail surveys of 4,000 randomly selected landowners. Results indicate that attitudes and knowledge of forestry programs may be more influential in a landowner's decision to participate than monetary incentives.
2PI nonequilibrium versus transport equations for an ultracold Bose gas

description: The far-from-equilibrium dynamics of an ultracold, one-dimensional Bose gas is studied. The focus is set on the comparison between the solutions of fully dynamical evolution equations derived from the 2PI effective action and their corresponding kinetic approximation in the form of Boltzmann-type transport equations. It is shown that during the time evolution of the gas a kinetic description which includes non-Markovian memory effects in a gradient expansion becomes valid. The time scale at which this occurs is shown to exceed significantly the time scale at which the system's evolution enters a near-equilibrium drift period where a fluctuation dissipation relation is found to hold and which would seem to be predestined for the kinetic approximation.

description: The issue at hand revolves around the increasing adoption of Disruptive Technologies (DTs) in European Public Administrations (PAs), where cutting-edge technologies like AI, IoT, and Big Data are reshaping how services are delivered. While these technologies hold the potential for efficiency gains and cost savings, they raise significant ethical and social concerns. The European Union has been actively working on a legal framework to regulate AI and emerging technologies, but changes are frequent, causing uncertainty for adopting organizations. Equipping PAs with digital skills and ethics expertise is a pressing need. 

For Public Administrations and citizens, responsible adoption of DTs is crucial to avoid potential harm, legal implications, and governance risks. A notable case in the Netherlands highlights the dangers of discriminatory biases in algorithms. On the positive side, ethical technology adoption promises risk reduction, streamlined procedures, improved service delivery, and strengthened trust in public institutions. 

To address these challenges, policymakers should focus on analysing their context, building multidisciplinary teams, putting in place standardized governance procedures involving risk assessment and mitigation and legal consultations, adopting code of conducts, providing training programs to public servants and engaging citizens. 

At the European level, investment priorities should be directed towards R&D funding for ethical DT adoption, digital skills training for public servants, simplifying innovation procurement, enabling AI Act compliance, creating public awareness on digital ethics, and supporting the development of ethical DT solutions in Europe. Additionally, fostering international collaboration on ethical tech research and deployment is crucial for establishing global standards and guidelines. 

In conclusion, responsible adoption of Disruptive Technologies in European PAs is imperative to harness their benefits while safeguarding against potential risks and ethical concerns. Policymakers should focus on comprehensive approaches and targeted investments to ensure a trustworthy and ethical digital transformation.

description: This study evaluates the attitudes of U.S. (Kansas) farmers regarding "free-trade" and "free-market" policy environments. In contrast to earlier studies, non-specific policy attitudes are evaluated. A direct measure of farm program benefits is also included. Attitudes vary significantly with farm and operator characteristics. Support for free trade was shown to decrease with education and experience, to increase for farms with relatively more rented land, and to increase as total farm wealth increased. Support for free-trade was also higher for crop farms. Farms receiving more government payments are less likely to favor a free-trade policy environment.

description: The random switching of measurement bases is commonly assumed to be a necessary step of quantum key distribution protocols. In this paper we show that switching is not required for coherent state continuous variable quantum key distribution. We show this via the no-switching protocol which results in higher information rates and a simpler experimental setup. We propose an optimal eavesdropping attack against this protocol, for individual Gaussian attacks, and we investigate and compare the no-switching protocol applied to the original BB84 scheme.

description: A 1D Dirac tight-binding model is considered and it is shown that its nonrelativistic limit is the 1D discrete Schr?odinger model. For random Bernoulli potentials taking two values (without correlations), for typical realizations and for all values of the mass, it is shown that its spectrum is pure point, whereas the zero mass case presents dynamical delocalization for specific values of the energy. The massive case presents dynamical localization (excluding some particular values of the energy). Finally, for general potentials the dynamical moments for distinct masses are compared, especially the massless and massive Bernoulli cases.

description: We analyse a preferential urn model with randomness using the replica method. The preferential urn model is a stochastic model based on the concept "the rich get richer." The replica analysis clarifies that the preferential urn model with randomness shows a fat-tailed occupation distribution. The analytical treatments and results would be useful for various research fields such as complex networks, stochastic models, and econophysics.

description: Due to their topological stability and spatial confinement, particle-like field configurations have gained significant interest in many areas of physics. Only recently, the first skyrmionic hopfion was proposed in light, but its higher-order analog in optics has stayed a theoretical construct so far, and direct experimental observations also prove difficult in non-optical systems. Here we overcome this challenge by the experimental realization and analysis of a second-order skyrmionic hopfion in the polarization and phase texture of a paraxial light field in three-dimensional space. Thereby, we exemplify advanced control of observed parameters in a localized space, pioneering further experimental studies on higher-order hopfions in optics and beyond.

Sharing and privacy using untrusted storage

Publisher: name: University of British Columbia

description: Broadband connections to the Internet are enabling a new set of applications and services. Of interest is the impact of this additional bandwidth on current file system models. These models are being challenged as the Internet is enabling global file access, cross-domain sharing, and the use of Internet-based storage services. Various network file systems [3, 15, 8] offer ubiquitous file access, research systems [9] have offered solutions to cross-domain sharing, and cryptographic file systems [2, 5] addressed concerns regarding the trust of system administrators and data security. The Internet model requires that all these ideas be integrated into a single system. This thesis describes a new file system called bFS that addresses the challenges of this new model by eliminating the assumption that servers (specifically, their administrators) are trusted. Instead, agents sue trusted to manage data, metadata, authentication with storage providers, and enforcing access control. This enables global access and cross-domain sharing using untrusted storage servers.
