description: The chlorination titanium blast furnace slag belongs to industrial waste, but after grinding, they can be used to prepare cementing fluids to realize the secondary utilization of solid waste resources. As a common additive, fluid loss additives are mostly used in oil well cement systems, and there is still a lot of room for development when applied to chlorination titanium blast furnace slag systems. In this paper, the AMPS/DN-1/DMC/AA tetramer fluid loss additive was synthesized by free radical polymerization and named as ADDA. After testing its adsorption, hydration and plugging experiments, the TOC results showed that with the increase of ADDA, the organic carbon absorption increased from 5.68 mg/L to 34.59 mg/L; the BET results showed that, with the increase of ADDA, the specific surface area decreased from 15.3976 m3/g to 8.4157 m3/g. Combined with the microscopic morphology and other tests, it is shown that ADDA can effectively adsorb slag particles due to the electrostatic interaction of the sulfonic and carboxyl group in its molecular structure and the steric effect of the quaternary amine group. In addition, ADDA can promote the hydration reaction of the slag and entangle with the hydration products to form a complex network structure, thereby changing the filter cake structure to produce a dense and uniform filter cake; Polymer macromolecules can also effectively block the "gap" and "holes" in the structure, greatly reducing the flow path of free water, thereby realizing the control of water loss.

description: Carbon dioxide (CO2) storage into geological formations is regarded as an important mitigation strategy for anthropogenic CO2 emissions to the atmosphere. This study first simulates the leakage of CO2 and brine from a storage reservoir through the caprock. Then, we estimate the resulting pressure changes at the zone overlying the caprock also known as Above Zone Monitoring Interval (AZMI). A data-driven approach of arbitrary Polynomial Chaos (aPC) Expansion is then used to quantify the uncertainty in the above zone pressure prediction based on the uncertainties in different geologic parameters. Finally, a global sensitivity analysis is performed with Sobol indices based on the aPC technique to determine the relative importance of different parameters on pressure prediction. The results indicate that there can be uncertainty in pressure prediction locally around the leakage zones. The degree of such uncertainty in prediction depends on the quality of site specific information available for analysis. The scientific results from this study provide substantial insight that there is a need for site-specific data for efficient predictions of risks associated with storage activities. The presented approach can provide a basis of optimized pressure based monitoring network design at carbon storage sites.

description: A generalized disclination (g.disclination) theory [AF15] has been recently introduced that goes beyond treating standard translational and rotational Volterra defects in a continuously distributed defects approach; it is capable of treating the kinematics and dynamics of terminating lines of elastic strain and rotation discontinuities. In this work, a numerical method is developed to solve for the stress and distortion fields of g.disclination systems. Problems of small and finite deformation theory are considered. The fields of a single disclination, a single dislocation treated as a disclination dipole, a tilt grain boundary, a misfitting grain boundary with disconnections, a through twin boundary, a terminating twin boundary, a through grain boundary, a star disclination/penta-twin, a disclination loop (with twist and wedge segments), and a plate, a lenticular, and a needle inclusion are approximated. It is demonstrated that while the far-field topological identity of a dislocation of appropriate strength and a disclination-dipole plus a slip dislocation comprising a disconnection are the same, the latter microstructure is energetically favorable. This underscores the complementary importance of all of topology, geometry, and energetics in understanding defect mechanics. It is established that finite element approximations of fields of interfacial and bulk line defects can be achieved in a systematic and routine manner, thus contributing to the study of intricate defect microstructures in the scientific understanding and predictive design of materials. Our work also represents one systematic way of studying the interaction of (g.)disclinations and dislocations as topological defects, a subject of considerable subtlety and conceptual importance [Mer79, AMK17].

description: Reducing greenhouse gas emissions (GHG) is an important social goal to mitigate climate change. A common mitigation paradigm is to consider strategy "wedges" that can be applied to different activities to achieve desired GHG reductions. In this policy analysis piece, we consider a wide range of possible strategies to reduce light-duty vehicle GHG emissions, including fuel and vehicle options, low carbon and renewable power, travel demand management and land use changes. We conclude that no one strategy will be sufficient to meet GHG emissions reduction goals to avoid climate change. However, many of these changes have positive combinatorial effects, so the best strategy is to pursue combinations of transportation GHG reduction strategies to meet reduction goals. Agencies need to broaden their agendas to incorporate such combination in their planning.

description: Most, if not all, stars are now believed to produce energetic outflows during their formation. Yet, almost 20 years after the discovery of bipolar outflows from young stars, the origins of this violent phenomenon are not well understood. One of the difficulties of probing the outflow process, particularly in the case of massive embedded stars, is a deficit of high spatial resolution observations. Here, we present sub-arcsecond-resolution mid-infrared images of one massive young stellar object, AFGL 2591, and its immediate surroundings. Our images, at 11.7, 12.5 and 18.0 microns, reveal a knot of emission ~6'' SW of the star, which may be evidence for a recent ejection event or an embedded companion star. This knot is roughly coincident with a previously seen near-infrared reflection nebula and a radio source, and lies within the known large-scale CO outflow. We also find a new faint NW source which may be another embedded lower-luminosity star. The IRAS mid-infrared spectrum of AFGL 2591 shows a large silicate absorption feature at 10 microns, implying that the primary source is surrounded by an optically thick dusty envelope. We discuss the interrelationship of these phenomena and suggest that mid-infrared imaging and spectroscopy provide powerful tools for probing massive star birth.

description: Most technologically relevant ferroelectrics typically lose piezoelectricity above the Curie temperature. This limits their use to relatively low temperatures. In this Letter, exploiting a combination of flexoelectricity and simple functional grading, we propose a strategy for high-temperature electromechanical coupling in a standard thin film configuration. We use continuum modeling to quantitatively demonstrate the possibility of achieving apparent piezoelectric materials with large and temperature-stable electromechanical coupling across a widetemperature range that extends significantly above the Curie temperature. With Barium and Strontium Titanate, as example materials, a significant electromechanical coupling that is potentially temperature-stable up to 900 °C is possible.

description: Il lavoro di diploma consiste in un progetto didattico sul tema L’azienda e i suoi finanziatori. Il percorso è rivolto ad una classe di prima della Scuola cantonale di commercio di Bellinzona. Le lezioni sono suddivise in cinque tappe di apprendimento in cui vengono costruite le nozioni necessarie ad individuare le principali fonti di finanziamento. Il contenuto disciplinare si basa sullo studio di un caso utilizzato per le varie tappe di apprendimento: gli studenti sono chiamati ad aiutare un’azienda ticinese nell’indentificare e caratterizzare i metodi a loro disposizione per ottenere le risorse finanziarie necessarie. Le principali tipologie di fonti di finanziamento esterne ed interne sono quindi passate in rassegna, evidenziandone i vantaggi e gli svantaggi. Le metodologie didattiche sono alternativamente di tipo induttivo e dialogato, per permettere agli studenti di scoprire la materia, riflettendo sulla necessità di un determinato metodo di finanziamento. La classe affronta le varie tappe lavorando a coppie ed in gruppi, operando per discussione, in modalità dialogata e dove possibile ricostruendo le nozioni ricercate. I risultati della verifica mostrano che gli obiettivi richiesti sono stati in media raggiunti dalla classe a cui è stato sottoposto il progetto didattico. Relatore: Luca Berla.

description: This paper investigates the implementation of Field Dislocation Mechanics (FDM) theory for media with a periodic microstructure (i.e. the Nye dislocation tensor and the elastic moduli tensor are considered as spatially periodic continuous fields). In this context, the uniqueness of the stress and elastic distortion fields is established. This allows to propose an efficient numerical scheme based on Fourier transform to compute the internal stress field, for a given spatial distribution of dislocations and applied macroscopic stress. This numerical implementation is assessed by comparison with analytical solutions for homogeneous as well as heterogeneous elastic media. A particular insight is given to the critical case of stress-free dislocation microstructures which represent equilibrium solutions of the FDM theory.

description: Human papillomavirus (HPV) is one of the most common sexually transmitted infection in the United States and can lead to cervical, vulvovaginal, anal, penile, and oropharyngeal cancers. Compared with the general population, US military members are at a higher risk of HPV-related conditions, yet vaccination rates are relatively low in this population. As many service members may not be diagnosed with HPV-related cancers until after they leave active service, the objective of this study was to determine the incidence, prevalence, and economic burden of HPV-related cancers among US veterans. The study used the 2014–2018 Veterans Health Administration (VHA) database to identify newly diagnosed adult patients (cases) with HPV-related cancers, including cervical, vulvovaginal, anal, penile, and oropharyngeal cancers. Cases were matched by age, race, and sex to patients without HPV related cancer (controls). Outcome measures included annual incidence, prevalence, health care resource utilization (HCRU), and costs. These outcomes were calculated from the index date (first cancer diagnosis) through the earliest of 24 months, death, or end of study period. Adjusted results were examined using generalized linear models. The annual prevalence and incidence rates of HPV-related cancers ranged from 43 (anal) to 790 (oropharyngeal) cases per million (CPM), and four (anal) to 131 (cervical) CPM, respectively. Compared with controls, cases had significantly higher annual HCRU. Mean numbers of annual inpatient hospitalizations were several times higher compared to controls (cervical: 6.7-times (×); vulvovaginal: 2.7×; penile: 6.6×; oropharyngeal: 10.2×; and anal: 14.9×; all p p HPV-related cancers may cause significant clinical and economic burden within the VHA system. Given the consequences of HPV-related cancers among veterans who did not have access to the vaccine, HPV vaccination of active military and eligible veterans should be considered a healthcare priority.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Let $X$ be a del Pezzo surface of degree $5$ defined over a field $F$. A theorem of Yu. I. Manin and P. Swinnerton-Dyer asserts that every Del Pezzo surface of degree $5$ is rational. In this paper we generalize this result as follows. Recall that del Pezzo surfaces of degree $5$ over a field $F$ are precisely the twisted $F$-forms of the moduli space $\overline{M_{0, 5}}$ of stable curves of genus $0$ with $5$ marked points. Suppose $n \geq 5$ is an integer, and $F$ is an infinite field of characteristic $\neq 2$. It is easy to see that every twisted $F$-form of $\overline{M_{0, n}}$ is unirational over $F$. We show that (a) if $n$ is odd, then every twisted $F$-form of $\overline{M_{0, n}}$ is rational over $F$. (b) If $n$ is even, there exists a field extension $F/k$ and a twisted $F$-form $X$ of $\overline{M_{0, n}}$ such that $X$ is not retract rational over $F$.

description: We study the evolution of magnetic fields in turbulent hot plasma of the early Universe accounting for the chiral magnetic effect. The magnetohydrodynamic turbulence is modeled by replacing the matter velocity in the advection term in the Faraday equation with the Lorentz force. The system of the kinetic equations for the spectra of the densities of the magnetic helicity and the magnetic energy, as well as for the chiral imbalance, is derived. The amplification of the magnetic field is shown to result from the presence of the chiral magnetic effect solely. The system of the kinetic equations is solved numerically in primordial plasma after the electroweak phase transition. The influence of the matter turbulence on the magnetic field evolution is examined for different seed magnetic fields.

The model exhibits phase transition of the second-order between the antiphase in low temperature and the modulated phase in high temperature. Observing the domain wall free energy, we confirm that the modulation period in high-temperature side is well explained by the free-fermion picture.

description: This paper aims to apply a recently developed numerical scheme toward multi-time scale modeling, which we refer to as ‘Practical Time Averaging’ (PTA), to molecular dynamical (MD) systems. In the first part, we investigate the fine-scale dynamics of a one-dimensional chain of identical particles under cyclic loading. Assuming a double-well interatomic potential among adjacent particles leads to a phase transition between two distinct equilibrium states. Specifically, we study the macroscopic stress–strain behavior of the dynamical chain in three settings, i.e. Newtonian MD, Newtonian MD with viscous dissipation and Newtonian MD with thermostat. Rate-independent high frequency oscillations are observed in Newtonian MD due to an instability that is related to the non-convexity of the strain energy. This is stabilized by adding viscosity or a thermostat, which leads to strong hysteresis that is consistent with quasi-static results (i.e. lattice statics). In the second part, we first define coarse variables as finite time averages of phase functions in MD. Then we apply the technique of PTA developed in Tan et al. (2013) to numerically approximate the coarse dynamics for the time averaged quantities. The tested model problems include a two-dimensional lattice made of stoichiometric Nickel–Manganese undergoing detwinning and a three-dimensional atomic chain made of face-centered cubic (FCC) Nickel under uniaxial tension. The macroscopic features (such as space-time averaged strain/stress) are obtained from coarse dynamics. It is also shown that the time savings become significant when the loading rate is small.

The Flared Disc Project: RXTE and ASCA Observations of X 1822-371

description: We present archival RXTE and simultaneous ASCA data of the eclipsing low mass X-ray binary (LMXB) X 1822-371. Our spectral analysis shows that a variety of simple models can fit the spectra relatively well. Of these models, we explore two in detail through phase resolved fits. These two models represent the case of a very optically thick and a very optically thin corona. While systematic residuals remain at high energies, the overall spectral shape is well-approximated. The same two basic models are fit to the X-ray light curve, which shows sinusoidal modulations interpreted as absorption by an opaque disc rim of varying height. The geometry we infer from these fits is consistent with previous studies: the disc rim reaches out to the tidal truncation radius, while the radius of the corona (approximated as spherical) is very close to the circularization radius. Timing analysis of the RXTE data shows a time lag from hard to soft consistent with the coronal size inferred from the fits. Neither the spectra nor the light curve fits allow us to rule out either model, leaving a key ingredient of the X 1822-371 puzzle unsolved. Furthermore, while previous studies were consistent with the central object being a 1.4 Msol neutron star, which has been adopted as the best guess scenario for this system, our light curve fits show that a white dwarf or black hole primary can work just as well. Based on previously published estimates of the orbital evolution of X 1822-371, however, we suggest that this system contains either a neutron star or a low mass (~ 2.5 Msol) black hole and is in a transitional state of duration shortward of 10^7 years.

description: Magnetosphere at ion kinetic scales, or mini-magnetosphere, possesses unusual features as predicted by numerical simulations. However, there are practically no data on the subject from space observations and the data which are available are far too incomplete. In the present work we describe results of laboratory experiment on interaction of plasma flow with magnetic dipole with parameters such that ion inertia length is smaller than a size of observed magnetosphere. A detailed structure of non-coplanar or out-of-plane component of magnetic field has been obtained in meridian plane. Independence of this component on dipole moment reversal, as was reported in previous work, has been verified. In the tail distinct lobes and central current sheet have been observed. It was found that lobe regions adjacent to boundary layer are dominated by non-coplanar component of magnetic field. Tail-ward oriented electric current in plasma associated with that component appears to be equal to ion current in the frontal part of magnetosphere and in the tail current sheet implying that electrons are stationary in those regions while ions flow by. Obtained data strongly support the proposed model of mini-magnetosphere based on two-fluid effects as described by the Hall term.

description: Abstract: "We consider the problem of finding the shape of an airfoil which produces a pressure distribution closest to a desired one. The flow is modeled by the nonlinear potential equations of compressible flow. The problem is formulated as an optimization problem constrained by a discrete approximation to a nonlinear boundary value problem. We present a new parallel infeasible path method for this class of optimization problem. The method is based on a null space representation tailored to the structure of the constraint Jacobian matrix. The resulting null space projections formally involve inverses of the stiffness matrix. The algorithm requires only two stiffness matrix solves per optimization iteration, in contrast to a conventional path-following method, which resolves the full physics at each iteration. The algorithm has been implemented on a CM-2, and requires no new data structures or communication patterns beyond those needed for numerical solution of the boundary value problem. We discuss numerical evidence for the superiority of the new method relative to a conventional path-following approach."
Adsorption of the astatine species on gold surface: a relativistic density functional theory study

description: We report on first-principle based studies of the adsorption interaction of astatine species on a gold surface. These studies are aimed primarily at the support and interpretation of gas chromatographic experiments with Superheavy Elements, tennessine (Ts, $Z=117$) as the heavier homologue of At and possibly nihonium (Nh, $Z=113$) as its pseudo-homologue. The adsorption energies of elemental astatine or the corresponding monohydroxide on a stable gold (111) surface are estimated using gold clusters with up to 69 atoms in order to simulate the adsorption site. To simulate the electronic structure of $\rm At-Au_n$ and $\rm AtOH-Au_n$ complexes, we combine accurate shape-consistent relativistic pseudopotentials and non-collinear two-component relativistic density functional theory. The predicted adsorption energies for At and AtOH on gold are $\rm 130 \pm 10$ kJ/mol and $\rm 90 \pm 10$ kJ/mol, respectively.

Predicted Stellar Kinematics of a Kiloparsec-Scale Nuclear Disc (or Ring) in the Milky Way

description: In Debattista et al. (2015), we proposed that a kiloparsec-scale nuclear disc is responsible for the high-velocity secondary peak in the stellar line-of-sight velocity distributions (LOSVDs) seen at positive longitudes in the bulge by the Apache Point Observatory Galactic Evolution Experiment (APOGEE). Here, we make further qualitative but distinctive predictions of the kinematic properties of a nuclear disc, including for the LOSVDs at negative longitudes (which APOGEE-2 will observe) and examine the proper motions throughout the disc. Since a nuclear ring is also able to produce similar high-velocity LOSVD peaks, we present predictions for the proper motion signatures which distinguish between a nuclear disc and a nuclear ring. We also demonstrate that the stars in a nuclear disc, which would be on x2 orbits perpendicular to the bar, can remain on these orbits for a long time and can therefore be old. We show that such (old) nuclear discs of comparable size exist in external galaxies.

description: Plug-in hybrid electric vehicles (PHEVs), which use electricity from the grid to power a portion of travel, could play a role in reducing greenhouse gas (GHG) emissions from the transport sector. However, meaningful GHG emissions reductions with PHEVs are conditional on low-carbon electricity sources. We assess life cycle GHG emissions from PHEVs and find that they reduce GHG emissions by 32% compared to conventional vehicles, but have small reductions compared to traditional hybrids. Batteries are an important component of PHEVs, and GHGs associated with lithium-ion battery materials and production account for 2-5% of life cycle emissions from PHEVs. We consider cellulosic ethanol use and various carbon intensities of electricity. The reduced liquid fuel requirements of PHEVs could leverage limited cellulosic ethanol resources. Electricity generation infrastructure is long-lived, and technology decisions within the next decade about electricity supplies in the power sector will affectthe potential for large GHG emissions reductions with PHEVs for several decades.

description: We consider coupled atomic-molecular Bose-Einstein condensate system in a quasi-one-dimensional trap. In the vicinity of a Feshbach resonance the system can reveal soliton-like behavior. We analyze bright soliton solutions for the system in the trap and in the presence of the interactions between particles. We show that with increasing number of particles in the system two bright soliton solutions start resembling dark soliton profiles known in an atomic Bose-Einstein condensate with repulsive interactions between atoms. We analyze also methods for experimental preparation and detection of the soliton states.
