description: We use discontinuous molecular dynamics and grand-canonical transition-matrix Monte Carlo simulations to explore how confinement between parallel hard walls modifies the relationships between packing fraction, self-diffusivity, partial molar excess entropy, and total excess entropy for binary hard-sphere mixtures. To accomplish this, we introduce an efficient algorithm to calculate partial molar excess entropies from the transition-matrix Monte Carlo simulation data. We find that the species-dependent self-diffusivities of confined fluids are very similar to those of the bulk mixture if compared at the same, appropriately defined, packing fraction up to intermediate values, but then deviate negatively from the bulk behavior at higher packing fractions. On the other hand, the relationships between self-diffusivity and partial molar excess entropy (or total excess entropy) observed in the bulk fluid are preserved under confinement even at relatively high packing fractions and for different mixture compositions. This suggests that the partial molar excess entropy, calculable from classical density functional theories of inhomogeneous fluids, can be used to predict some of the nontrivial dynamical behaviors of fluid mixtures in confined environments.

description: Modern compiler implementations use the Static Single Assignment representation as a way to efficiently implement optimizing algorithms. However this representation is not well adapted to architectures with a predicated instruction set. The Psi-SSA representation extends the SSA representation such that standard SSA algorithms can be easily adapted to an architecture with a fully predicated instruction set. A new pseudo operation, the Psi operation, is introduced to merge several conditional definitions into a unique definition.

description: Flue gas desulfurization (FGD) gypsum was surface-applied on a poorly drained cultivated Coastal Plain soil in Maryland containing excessive amounts of plant-available phosphorus (P). Using a constant head double-ring infiltrometer, a field experiment indicated a slight increase in final infiltration rate (FIR) at 10 and 15 Mg ha-1 application rates, however a laboratory rainfall simulation showed no significant effect of FGD gypsum on FIR. Water extractable phosphorus (WEP) decreased by 13-47% one year after application of FGD gypsum. Linear relationships were established between Mehlich 3 (M3) and ammonium oxalate extractions of P and aluminum (Al) (r2 = 0.83, 0.56, respectively), supporting previous research on the reliability of M3 in place of ammonium oxalate to predict P loss. One year after FGD gypsum application total S was 3-150% higher at 15 cm and 44-74% higher at 30 cm depths. No significant difference in total S was apparent at deeper depths.

description: Computational models were built for the endoplasmic reticulum (ER), trans-Golgi network (TGN), and plasma membranes (PM) of yeast Saccharomyces cerevisiae. Based on experimental data, ergosterol, phosphatidic acid, phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and phosphatidylinositol lipids were included. Lipid packing, order parameters (SCD), electron density profiles (EDPs), and lipid rotation were studied for each model. The average surface area per lipid decreased from 63.82±0.03 Å2 in the ER to 47.09±0.12 Å2 at the PM; while the compressibility modulus (KA) varied in opposite direction (PM>TGN>ER). The SCD values were higher (more ordered) for the PM lipids than the ER and TGN membranes by a factor of 1.5. The bilayer thickness estimated from EDPs was larger for the PM (43.9±0.1 Å) than the ER or TGN (37.6±0.1 Å). These properties followed expected experimental trends and were compared against a previous model built by Jo et al. (Biophys J. 2009, 97:50-58).

description: The perceived risk and reward for a given situation can vary depending on resource availability, accumulated wealth, and other extrinsic factors such as individual backgrounds. Based on this general aspect of everyday life, here we use evolutionary game theory to model a scenario with randomly perturbed payoffs in a prisoner's dilemma game. The perception diversity is modeled by adding a zero-average random noise in the payoff entries and a Monte-Carlo simulation is used to obtain the population dynamics. This payoff heterogeneity can promote and maintain cooperation in a competitive scenario where only defectors would survive otherwise. In this work, we give a step further understanding the role of heterogeneity by investigating the effects of quenched disorder in the critical properties of random games. We observe that payoff fluctuations induce a very slow dynamic, making the cooperation decay behave as power laws with varying exponents, instead of the usual exponential decay after the critical point, showing the emergence of a Griffiths phase. We also find a symmetric Griffiths phase near the defector's extinction point when fluctuations are present, indicating that Griffiths phases may be frequent in evolutionary game dynamics and play a role in the coexistence of different strategies.

description: This report, with its structure along the five dimensions and the barriers and enablers therein, aims

to enrich existing frameworks for analyzing coastal governance. Assessing the different

dimensions that shape governance systems' capacity to respond to complex challenges is key to

achieving change. Taking stock of the dimensions, the different positions that have emerged in

different governance systems, as well as assessing the interrelations between the dimensions and

their constitutive components, leads to useful insights into the actual functioning of governance

systems. By knowing the main characteristics of each governance system, the specific barriers and

enablers that are present in those systems can be unveiled and future courses of action decided

upon.

description: Galactic cosmic rays are energetic particles important in the context of life. Many works have investigated the propagation of Galactic cosmic rays through the Sun's heliosphere. However, the cosmic ray fluxes in M dwarf systems are still poorly known. Studying the propagation of Galactic cosmic rays through the astrospheres of M dwarfs is important to understand the effect on their orbiting planets. Here, we focus on the planetary system GJ 436. We perform simulations using a combined 1D cosmic ray transport model and 1D Alfvén-wave-driven stellar wind model. We use two stellar wind set-ups: one more magnetically-dominated and the other more thermally-dominated. Although our stellar winds have similar magnetic field and velocity profiles, they have mass-loss rates two orders of magnitude different. Because of this, they give rise to two different astrosphere sizes, one ten times larger than the other. The magnetically-dominated wind modulates the Galactic cosmic rays more at distances < 0.2 au than the thermally-dominated wind due to a higher local wind velocity. Between 0.2 and 1 au the fluxes for both cases start to converge. However, for distances > 10 au, spatial diffusion dominates, and the flux of GeV cosmic rays is almost unmodulated. We find, irrespective of the wind regime, that the flux of Galactic cosmic rays in the habitable zone of GJ 436 (0.2 - 0.4 au) is comparable with intensities observed at Earth. On the other hand, around GJ 436 b (0.028 au), both wind regimes predict Galactic cosmic ray fluxes that are approximately $10^4$ times smaller than the values observed at Earth.

description: We propose a method of neural evolution structures (NESs) combining artificial neural networks (ANNs) and evolutionary algorithms (EAs) to generate High Entropy Alloys (HEAs) structures. Our inverse design approach is based on pair distribution functions and atomic properties and allows one to train a model on smaller unit cells and then generate a larger cell. With a speed-up factor of approximately 1000 with respect to the SQSs, the NESs dramatically reduces computational costs and time, making possible the generation of very large structures (over 40,000 atoms) in few hours. Additionally, unlike the SQSs, the same model can be used to generate multiple structures with the same fractional composition.

description: We study a model for a protein searching for a target, using facilitated diffusion, on a DNA molecule confined in a finite volume. The model includes three distinct pathways for facilitated diffusion: (a) sliding - in which the protein diffuses along the contour of the DNA (b) jumping - where the protein travels between two sites along the DNA by three-dimensional diffusion, and finally (c) intersegmental transfer - which allows the protein to move from one site to another by transiently binding both at the same time. The typical search time is calculated using scaling arguments which are verified numerically. Our results suggest that the inclusion of intersegmental transfer (i) decreases the search time considerably (ii) makes the search time much more robust to variations in the parameters of the model and (iii) that the optimal search time occurs in a regime very different than that found for models which ignore intersegmental transfers. The behavior we find is rich and shows surprising dependencies, for example, on the DNA length.

description: Industrial change forces enterprises to constantly adjust their organizational structures in order to stay competitive. In this regard, research acknowledges the potential of Reference Enterprise Architectures (REA). This thesis proposes REAM—a method for developing REAs. After contrasting organizations' needs with approaches available in the current knowledge base, this work identifies the absence of method support for REA development. Proposing REAM, the author aims to close this research gap and evaluates the method's utility by applying REAM in different naturalistic settings.

description: Using the recently proposed definition of a conserved spin-current operator [J. Shi et al., Phys. Rev. Lett. 96, 076604 (2006)] we explore the frequency dependent spin Hall conductivity for a two-dimensional electron gas with Rashba and Dresselhaus spin-orbit interaction in response to an oscillating electric field. We show that the optical spectrum of the spin Hall conductivity exhibit remarkable changes when the new definition of spin current is applied. Such behavior is mainly due to a significant contribution of the spin torque term which is absent in the conventional form of the spin current. In addition, it is observed that the magnitude and direction of the dynamic spin Hall current strongly depends on the electric field frequency as with the interplay of the spin-orbit coupling strengths.

description: We report a comprehensive high-pressure study on the antiferromagnetic topological insulator EuSn2As2 up to 21.1 GPa through measurements of synchrotron x-ray diffraction, electrical resistance, magnetic resistance, and Hall transports combined with first-principles calculations. No evident trace of a structural phase transition is detected. The Neel temperatures determined from resistance are increased from 24 to 77 K under pressure, which is resulted from the enhanced magnetic exchange couplings between Eu2+ ions yielded by our first-principles calculations. The negative magnetoresistance of EuSn2As2 persists to higher temperatures accordantly. However, the enhancement of the observed Néel temperatures deviates from the calculations obviously above 10.0 GPa. In addition, the magnitude of the magnetoresistance, the Hall coefficients, and the charge carrier densities show abrupt changes between 6.9 to 10.0 GPa. The abrupt changes probably originate from a pressure induced valence change of Eu ions from a divalent state to a divalent and trivalent mixed state. Our results provide insights into variation of the magnetism of EuSn2As2 and similar antiferromagnetic topological insulators under pressure.

Cubic Action in Double Field Theory

description: We study target space theory on a torus for the states with $N_L+N_R=2$ through Double Field Theory. The spin-two Fierz-Pauli fields are not allowed when all spatial dimensions are non-compact. The massive states provide both non-vanishing momentum and winding numbers in the target space theory. To derive the cubic action, we provide the unique constraint for $N_L\neq N_R$ compatible with the integration by part. We first make a correspondence of massive and massless fields. The quadratic action is gauge invariant by introducing the mass term. We then proceed to the cubic order. The cubic action is also gauge invariant by introducing the coupling between the one-form field and other fields. The massive states do not follow the consistent truncation. One should expect the self-consistent theory by summing over infinite modes. Hence the naive expectation is wrong up to the cubic order. In the end, we show that the momentum and winding modes cannot both appear for only one compact doubled space.

A two-color Hanle-MOKE technique (based on continuous-wave excitation) and time-resolved Kerr rotation in the regime of resonant spin amplification (based on pulsed excitation) provide a complementary measure of electron spin relaxation time. Influence of electron localization on long-lived spin coherence is examined by means of spectral and temperature dependencies. Various scenarios of spin polarization generation (via the trion and exciton states) are analyzed and difference between continuous-wave and pulsed excitations is considered. Effects related to inhomogeneous distribution of $g$-factor and anisotropic spin relaxation time on measured quantities are discussed.

description: Charge, like mass in Newtonian mechanics, is an irreducible element of electromagnetic theory that must be introduced ab initio. Its origin is not properly a part of the theory. Fields are then defined in terms of forces on either masses--in the case of Newtonian mechanics, or charges in the case of electromagnetism. General Relativity changed our way of thinking about the gravitational field by replacing the concept of a force field with the curvature of space-time. Mass, however, remained an irreducible element. It is shown here that the Reissner-Nordstrom solution to the Einstein field equations tells us that charge, like mass, has a unique space-time signature.

description: We present a detailed study of $B\to K_1(1270) γ$ and $B\to K_1(1400) γ$ decays. Using the light-cone sum rule technique, we calculate the $B\to K_{1A} (1^3P_1)$ and $B\to K_{1B} (1^1P_1)$ tensor form factors, $T_1^{K_{1A}}(0)$ and $T_1^{K_{1B}}(0)$, where the contributions are included up to the first order in $m_{K_1}/m_b$. We resolve the sign ambiguity of the $K_1(1270)$--$K_1(1400)$ mixing angle $θ_{K_1}$ by defining the signs of decay constants, $f_{K_{1A}}$ and $f_{K_{1B}}^\perp$. From the comparison of the theoretical calculation and the data for decays $B\to K_1 γ$ and $τ^-\to K_1^-(1270)ν_τ$, we find that $θ_{K_1}=-(34\pm 13)^\circ$ is favored. In contrast to $B\to K^* γ$, the hard-spectator contribution suppresses the $B\to K_1(1270) γ$ and $B\to K_1(1400) γ$ branching ratios slightly. The predicted branching ratios are in agreement with the Belle measurement within the errors. We point out that a more precise measurement for the ratio $R_{K_1}={\cal B}(B\to K_1(1400)γ)/{\cal B}(B\to K_1(1270)γ)$ can offer a better determination for the $θ_{K_1}$ and consequently the theoretical uncertainties can be reduced.

description: A generalized fractional derivative (GFD) definition is proposed in this work. For a differentiable function that can be expanded by Taylor series, we show that D^Elafa*D^Beta f(t)=D^(Elafa+Beta)f(t). GFD is applied for some functions in which we investigate that GFD coincides with Caputo and Riemann-Liouville fractional derivatives' results. The solutions of Riccati fractional differential equation are simply obtained via GFD. A comparison with other definitions is also discussed. The results show that the proposed definition in this work gives better accuracy than the commonly known conformable derivative definition. Therefore, GFD has some advantages in comparison with other definitions in which a new path is provided for simple analytical solutions of many problems in the context of fractional calculus.

description: Extragalactic foregrounds in Cosmic Microwave Background (CMB) temperature maps lead to significant biases in CMB lensing reconstruction if not properly accounted for. Combinations of multi-frequency data have been used to minimize the overall map variance (internal linear combination, or ILC), or specifically null a given foreground, but these are not tailored to CMB lensing. In this paper, we derive an optimal multi-frequency combination to jointly minimize CMB lensing noise and bias. We focus on the standard lensing quadratic estimator, as well as the "shear-only" and source-hardened estimators, whose responses to foregrounds differ. We show that an optimal multi-frequency combination is a compromise between the ILC and joint deprojection, which nulls the thermal Sunyaev-Zel'dovich (tSZ) and Cosmic Infrared Background (CIB) contributions. In particular, for a Simons Observatory-like experiment with $\ell_{\text{max},T}=3000$, we find that profile hardening alone (with the standard ILC) reduces the bias to the lensing power amplitude by $40\%$, at a $20\%$ cost in noise, while the bias to the cross-correlation with a LSST-like sample is reduced by nearly an order of magnitude at a $10\%$ noise cost, relative to the standard quadratic estimator. With a small amount of joint deprojection the bias to the profile hardened estimator can be further reduced to less than half the statistical uncertainty on the respective amplitudes, at a $20\%$ and $5\%$ noise cost for the auto- and cross-correlation respectively, relative to the profile hardened estimator with the standard ILC weights. Finally, we explore possible improvements with more aggressive masking and varying $\ell_{\text{max,}T}$.

description: Analysis of EDGES data shows an absorption signal of the redshifted 21-cm line of atomic hydrogen at $z\sim 17$ which is stronger than expected from the standard $Λ$CDM model. The absorption signal interpreted as brightness temperature $T_{21}$ of the 21-cm line gives an amplitude of $-$500$_{-500}^{+200}$ mK at 99\% C.L. which is a 3.8$σ$ deviation from what the standard $Λ$CDM cosmology gives. We present a particle physics model for the baryon cooling where a fraction of the dark matter resides in the hidden sector with a $U(1)$ gauge symmetry and a Stueckelberg mechanism operates mixing the visible and the hidden sectors with the hidden sector consisting of dark Dirac fermions and dark photons. The Stueckelberg mass mixing mechanism automatically generates a millicharge for the hidden sector dark fermions providing a theoretical basis for using millicharged dark matter to produce the desired cooling of baryons seen by EDGES by scattering from millicharged dark matter. We compute the relic density of the millicharged dark matter by solving a set of coupled equations for the dark fermion and dark photon yields and for the temperature ratio of the hidden sector and the visible sector heat baths. For the analysis of baryon cooling, we analyze the evolution equations for the temperatures of baryons and millicharged dark matter as a function of the redshift. We exhibit regions of the parameter space which allow consistency with the EDGES data. We note that the Stueckelberg mechanism arises naturally in strings and the existence of a millicharge would point to its string origin.

On an alternative quantization of R-NS strings
Creators: name: Yuki, Tsubasa
name: Nakayama, Yu
Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We investigate an alternative quantization of R-NS string theory. In the alternative quantization, we define the distinct vacuum for the left-moving mode and the right-moving mode by exchanging the role of creation operators and annihilation operators in the left-moving sector. The resulting string theory has only a finite number of propagating degrees of freedom. We show that an appropriate choice of the GSO projection makes the theory tachyon free. The spectrum coincides with the massless sector of type IIA or type IIB superstring theory without any massive excitations.

Effect of a Tertiary Butyl Group on Polar Solvation Dynamics in Aqueous Solution: A Computational Approach

description: The current computational study investigates the changes in solvation dynamics of water when introducing hydrophobic side chains to the molecular probe N-methyl-6-oxyquinolinium betaine. High precision transient fluorescence and absorption measurements published in the companion paper revealed an influence of hydrophobic sidechain alterations on the observed solvation dynamics of a chromophore in water. As the influence of shape, size and structure of chromophores on the time-dependent Stokes shift was so far thought to play a role only in slowly rotating solvents compared to the solute or if the hydrogen bonding ability of the solute changes, this finding is quite unexpected. Analysis of the time-dependent Stokes shift obtained from nonequilibrium simulations corroborates experimental retardation factors and activation energies, and indicates that solute motion, namely vibration, is mainly responsible for the observed retardation of solvation dynamics. The faster dynamics around the smaller chromophore is in fact achieved by some normal modes located at the pyridinium part of the chromophore. Rotation also contributes to a very small extent to hydration dynamics, but for small and large derivatives alike. Local residence times furthermore reveal slight retardations in the first solvent shell around the chromophores. The current picture of the solute acting as a passive molecular probe therefore needs to be revised even for solvents like water.

A mono-material Nernst thermopile with hermaphroditic legs

description: A large transverse thermoelectric response, known as anomalous Nernst effect (ANE) has been recently observed in several topological magnets. Building a thermopile employing this effect has been the subject of several recent propositions. Here, we design and build a thermopile with an array of tilted adjacent crystals of Mn$_3$Sn. The design employs a single material and replaces pairs of P and N thermocouples of the traditional design with hermaphroditic legs. The design exploits the large lag angle between the applied field and the magnetization, which we attribute to the interruption of magnetic octupoles at the edge of $xy$-plane. Eliminating extrinsic contacts between legs will boost the efficiency, simplify the process and pave the way for a new generation of thermopiles.

Role of Pax8 transcriptional factor in the differentiated thyroid
Creators: name: Marotta, Pina
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: In Pax8-/- mice the thyroid anlage disappears around E11.5. At birth the gland appears as a rudimentary structure composed only of C cells while thyroid follicular cells are undetectable. Thus, this model does not allow the study of  Pax8 function in the postnatal thyroid.
To address the role of Pax8 in the differentiated thyroid, I  established novel strains amenable to thyroid follicular cell-specific conditional knockout of Pax8 gene using the Cre/lox system. A genetically modified mouse strain (Pax8fl/fl) harbouring a floxed allele of Pax8 was generated. These mice were crossed  with  two different Cre mice,  a Pax8Cre/+ strain expressing  constitutively  Cre recombinase by embryonic day 8.5 and a Tg-CreER strain in which Cre is active in thyroid follicular cells following tamoxifen injection.
Pax8Cre/fl  mice do not display an overt phenotype during embryonic life. However, 3-week old Pax8Cre/fl  pups  show a hypothyroid phenotype characterized by both an increased serum TSH value and a significant reduction in body weight when compared with their wild type littermates. In  Pax8Cre/fl  animals the thyroid gland  is hypoplastic and shows the absence of the follicular structure; moreover, the expression of many thyroid specific genes, required for both hormone production and regulative functions, is completely abolished. In addition, survival of follicular cells is impaired.
The disruption of Pax8 in adult life (Pax8ko/fl;Tg-CreER strain) seems to be not efficient and thyroid structure appears comparable to that of wild type. However, the absence of a clear phenotype in the Pax8ko/fl;TgCreER thyroid could be due to the compensatory  proliferation of cells in which Pax8 has not been inactivated.
In conclusion, in my thesis work I demonstrated in vivo that Pax8 plays a key role in controlling both the expression of many thyroid specific genes and the survival of thyroid follicular cells.
Liminal space. The control of territory between formal and informal.

description: Lo sfondo entro il quale si colloca il lavoro di ricerca è da riferirsi allo studio dei processi di formazione dello spazio urbano da parte di attori organizzati (formali ed informali) capaci di esercitare controllo (sociale, economico, comportamentale, ecc.) e di influenzare processi decisionali sugli usi dello spazio.
La ricerca analizza come alcuni gruppi dominanti possano influenzare le scelte di governo territoriale, muovendosi in un mutevole spazio liminale tra formale e informale.
Partendo dal presupposto che formale ed informale non siano due ambiti nettamente distinti, ma in continua relazione fra loro, e che pertanto generino degli spazi di limite indefiniti e dinamici, la ricerca si pone l'obiettivo di comprendere la diversa “forma” e “composizione” di questi spazi decisionali in relazione al sistema di pianificazione formale in cui insistono, quali siano i soggetti che “abitano” questi spazi privilegiati e di quali strumenti “formali” si servano.
Per tale motivo si è scelto di confrontare due modelli di pianificazione (italiana e americana) molto diversi fra loro in relazione all'apprendimento e alla gestione delle pratiche informali.
Questi diversi sistemi di pianificazione danno vita a modelli diversi di informalità, a seconda della loro strutturazione e degli strumenti e norme di cui si servono. Il sistema informale si adatta mutualmente alle pratiche formali, definendo spazi liminali diversi.
Dall’analisi dei due sistemi si desumono considerazioni di carattere generale sulle possibili interazioni instaurabili tra formale ed informale in relazione alle caratteristiche dei sistemi di pianificazione, sull’effettivo utilizzo degli strumenti urbanistici esistenti e sulle modalità di manipolazione della rendita fondiaria. L’analisi consente, in tal modo, di riconsiderare l’adeguatezza dei diversi sistemi analizzati, rispetto ad obiettivi prestazionali enunciati, rispetto alla valutazione degli interessi in gioco e all’equità delle politiche distributive.
