description: When considering the Stone Law of Universality dynamics must be considered in order for it to apply to everything.

Mass=Field=Time==System Dynamics 

Zone or mass(State_A): represents the local state (e.g., particle, node, field pocket).

Importation or force (State_B): recursive influence or deviation accumulating toward threshold.

Shift or time(State_C): temporal or spatial redefinition of the system due to bifurcation.

The dynamic interaction, sequence, and continuity is the essence of unified oneness

description: In science, one observes correlations and invents theoretical models that describe them. In all sciences, besides quantum physics, all correlations are described by either of two mechanisms. Either a first event influences a second one by sending some information encoded in bosons or molecules or other physical carriers, depending on the particular science. Or the correlated events have some common causes in their common past. Interestingly, quantum physics predicts an entirely different kind of cause for some correlations, named entanglement. This new kind of cause reveals itself, e.g., in correlations that violate Bell inequalities (hence cannot be described by common causes) between space-like separated events (hence cannot be described by classical communication). Einstein branded it as spooky action at a distance. A real spooky action at a distance would require a faster than light influence defined in some hypothetical universally privileged reference frame. Here we put stringent experimental bounds on the speed of all such hypothetical influences. We performed a Bell test during more than 24 hours between two villages separated by 18 km and approximately east-west oriented, with the source located precisely in the middle. We continuously observed 2-photon interferences well above the Bell inequality threshold. Taking advantage of the Earth's rotation, the configuration of our experiment allowed us to determine, for any hypothetically privileged frame, a lower bound for the speed of this spooky influence. For instance, if such a privileged reference frame exists and is such that the Earth's speed in this frame is less than 10^-3 that of the speed of light, then the speed of this spooky influence would have to exceed that of light by at least 4 orders of magnitude.

The effect of temperature on drop size of black liquor sprays
Creators: name: Bennington, Chad Patrick Joseph
Publisher: name: University of British Columbia
Year: 2010

description: The effect of temperature on drop size of black liquor sprays produced by small grooved-core nozzles at near boiling point conditions was investigated. It was found that increasing temperature through the boiling point decreased the Sauter mean diameter in a smooth manner, by a magnitide accounted for by the viscosity decrease. In contrast, water sprayed through the same nozzle under similar conditions showed a near step increase in mean drop size for the same temperature increase through its boiling point. The mass-weighted distributions of drop size for black liquor sprays were much broader than those of water, or glycerol/water solutions having the same viscosity as black liquor. Increasing the temperature through the boiling point of black liquor shifted its drop size distribution to smaller diameters.
Simulations of helical inflationary magnetogenesis and gravitational waves

description: Using numerical simulations of helical inflationary magnetogenesis in a low reheating temperature scenario, we show that the magnetic energy spectrum is strongly peaked at a particular wavenumber that depends on the reheating temperature. Gravitational waves (GWs) are produced at frequencies between 3 nHz and 50 mHz for reheating temperatures between 150 MeV and 3x10^5 GeV, respectively. At and below the peak frequency, the stress spectrum is always found to be that of white noise. This implies a linear increase of GW energy per logarithmic wavenumber interval, instead of a cubic one, as previously thought. Both in the helical and nonhelical cases, the GW spectrum is followed by a sharp drop for frequencies above the respective peak frequency. In this magnetogenesis scenario, the presence of a helical term extends the peak of the GW spectrum and therefore also the position of the aforementioned drop toward larger frequencies compared to the case without helicity. This might make a difference in it being detectable with space interferometers. The efficiency of GW production is found to be almost the same as in the nonhelical case, and independent of the reheating temperature, provided the electromagnetic energy at the end of reheating is fixed to be a certain fraction of the radiation energy density. Also, contrary to the case without helicity, the electric energy is now less than the magnetic energy during reheating. The fractional circular polarization is found to be nearly hundred per cent in a certain range below the peak frequency range.

description: We investigate the efficiency of a gauge invariant input to a neural network for the path optimization method. While the path optimization with a completely gauge-fixed link-variable input has successfully tamed the sign problem in a simple gauge theory, the optimization does not work well when the gauge degrees of freedom remain. We propose to employ a gauge invariant input, such as plaquette, to overcome this problem. The efficiency of the gauge invariant input to the neural network is evaluated for the 2-dimensional $U(1)$ gauge theory with a complex coupling. The average phase factor is significantly enhanced by the path optimization with the plaquette input, indicating good control of the sign problem. It opens a possibility that the path optimization is available to complicated gauge theories, including Quantum Chromodynamics, in a realistic setup.

We show that this map is Poisson if the space of edge weights is equipped with a representative of a 6-parameter family of universal quadratic Poisson brackets and the Grasmannian is viewed as a Poisson homogeneous space of the general linear group equipped with an appropriately chosen R-matrix Poisson-Lie structure. We also prove that Poisson brackets on the Grassmannian arising in this way are compatible with the natural cluster algebra structure.

description: We present an original method to magnetically pattern thin layers of (Ga,Mn)As. It relies on local hydrogen passivation to significantly lower the hole density, and thereby locally suppress the carrier-mediated ferromagnetic phase. The sample surface is thus maintained continuous, and the minimal structure size is of about 200 nm. In micron-sized ferromagnetic dots fabricated by hydrogen passivation on perpendicularly magnetized layers, the switching fields can be maintained closer to the continuous film coercivity, compared to dots made by usual dry etch techniques.

The Lifetime of FRIIs in Groups and Clusters: Implications for Radio-Mode Feedback

description: We determine the maximum lifetime t_max of 52 FRII radio sources found in 26 central group galaxies from cross correlation of the Berlind SDSS group catalog with the VLA FIRST survey. Mock catalogs of FRII sources were produced to match the selection criteria of FIRST and the redshift distribution of our parent sample, while an analytical model was used to calculate source sizes and luminosities. The maximum lifetime of FRII sources was then determined via a comparison of the observed and model projected length distributions. We estimate the average FRII lifetime is 1.5x10^7 years and the duty cycle is ~8x10^8 years. Degeneracies between t_max and the model parameters: jet power distribution, axial ratio, energy injection index, and ambient density introduce at most a factor of two uncertainty in our lifetime estimate. In addition, we calculate the radio active galactic nuclei (AGN) fraction in central group galaxies as a function of several group and host galaxy properties. The lifetime of radio sources recorded here is consistent with the quasar lifetime, even though these FRIIs have substantially sub-Eddington accretion. These results suggest a fiducial time frame for energy injection from AGN in feedback models. If the morphology of a given extended radio source is set by large-scale environment, while the lifetime is determined by the details of the accretion physics, this FRII lifetime is relevant for all extended radio sources.

description: The Affleck-Kennedy-Lieb-Tasaki (AKLT) spin interacting model can be defined on an arbitrary graph. We explain the construction of the AKLT Hamiltonian. Given certain conditions, the ground state is unique and known as the Valence-Bond-Solid (VBS) state. It can be used in measurement-based quantum computation as a resource state instead of the cluster state. We study the VBS ground state on an arbitrary connected graph. The graph is cut into two disconnected parts: the block and the environment. We study the entanglement between these two parts and prove that many eigenvalues of the density matrix of the block are zero. We describe a subspace of eigenvectors of the density matrix corresponding to non-zero eigenvalues. The subspace is the degenerate ground states of some Hamiltonian which we call the block Hamiltonian.

description: We search for conditions under which a characteristic time scale for ordering dynamics towards either of two absorbing states in a finite complex network of interactions does not exist. With this aim, we study random networks and networks with mesoscale community structure built up from randomly connected cliques. We find that large heterogeneity at the mesoscale level of the network appears to be a sufficient mechanism for the absence of a characteristic time for the dynamics. Such heterogeneity results in dynamical metastable states that survive at any time scale.

Spectral type dependent rotational braking and strong magnetic flux in three components of the late-M multiple system LHS 1070

description: We show individual high resolution spectra of components A, B, and C of the nearby late-M type multiple system LHS 1070. Component A is a mid-M star, B and C are known to have masses at the threshold to brown dwarfs. From our spectra we measure rotation velocities and the mean magnetic field for all three components individually. We find magnetic flux on the order of several kilo-Gauss in all components. The rotation velocities of the two late-M objects B and C are similar (vsini = 16km/s), the earlier A component is spinning only at about half that rate. This suggests weakening of net rotational braking at late-M spectral type, and that the lack of slowly rotating late-M and L dwarfs is real. Furthermore, we found that magnetic flux in the B component is about twice as strong as in component C at similar rotation rate. This indicates that rotational braking is not proportional to magnetic field strength in fully convective objects, and that a different field topology is the reason for the weak braking in low mass objects.

description: Time-resolved fluorescence imaging is a key tool in biomedical applications, as it allows to non-invasively obtain functional and structural information. However, the big amount of collected data introduces challenges in both acquisition speed and processing needs. Here, we introduce a novel technique that allows to reconstruct a Giga-voxel 4D hypercube in a fast manner while only measuring 0.03 % of the information. The system combines two single-pixel cameras and a conventional 2D array detector working in parallel. Data fusion techniques are introduced to combine the individual 2D and 3D projections acquired by each sensor in the final high-resolution 4D hypercube, which can be used to identify different fluorophore species by their spectral and temporal signatures.

Il conflitto, ubiquo e in una certa misura normale e comprensibile, rispetto a luoghi e simboli che incarnano la memoria collettiva di una comunità (certo, pur sempre immaginata), è un tema che continua a insistere sul presente. Il dibattito impazzito sulle foibe, che puntualmente riemerge ogni volta che si avvicinano il giorno della memoria e quello del ricordo, oppure la scandalosa legge polacca, approvata da poco più di un anno, che impedisce anche solo parlare di una collaborazione allo sterminio nazista della popolazione civile polacca, sono due esempi che stanno a indicare chiaramente quanto sia aperta e irrisolta la tensione tra memoria – la concrezione simbolica di alcuni passaggi storici, ricordati e celebrati nel presente – e storia.

description: A primary goal at the interface of theoretical and experimental quantum magnetism is the investigation of exotic spin states, most notably quantum spin liquids (QSLs). Magnetic rare-earth ions go beyond the straightforward paradigm of geometrical frustration in Heisenberg antiferromagnets by introducing competing energy scales, and in particular their strong spin-orbit coupling creates multiple split crystal electric-field (CEF) levels, leading to anisotropic effective spin models with intrinsic frustration. While rare-earth delafossites have a triangular-lattice geometry, and thus have gained recent attention as candidates for hosting spin-1/2 QSL physics, the reliable extraction of effective spin models from the initial many-parameter CEF spectrum is a hard problem. Using the example of CsYbSe2, we demonstrate the unambiguous extraction of the Stevens-operators coefficients dictating the full CEF spectrum of Yb$^{3+}$ by translating these into parameters with a direct physical interpretation. Specifically, we combine low-field susceptibility measurements with resonant torsion magnetometry experiments in fields up to 60 T to determine a sufficiently large number of physical parameters -- effective Zeeman splittings, anisotropic van Vleck coefficients, and magnetotropic coefficients -- that the set of Stevens-operator coefficients is unique. Our crucial identification of the strong corrections to the Zeeman splitting of Kramers doublets as van Vleck coefficients has direct consequences for the interpretation of all anisotropic magnetic susceptibility measurements. Our results allow us to determine the nature and validity of an effective spin-1/2 model for CsYbSe2, to provide input for theoretical studies of such models on the triangular lattice, and to provide additional materials insight into routes for achieving magnetic frustration and candidate QSL systems in rare-earth compounds.

Our results are valid to leading order in the electromagnetic coupling constant but non-perturbatively in the SU(Nc) interactions. The spectral function of electromagnetic currents and other related observables exhibit an interesting structure as a function of the photon frequency and the quark mass. We discuss possible implications for heavy ion collision experiments.

description: We study the statistical and dynamic properties of the systems characterized by an ultrametric space of states and translationary non-invariant symmetric transition matrices of the Parisi type subjected to "locally constant" randomization. Using the explicit expression for eigenvalues of such matrices, we compute the spectral density for the Gaussian distribution of matrix elements. We also compute the averaged "survival probability" (SP) having sense of the probability to find a system in the initial state by time $t$. Using the similarity between the averaged SP for locally constant randomized Parisi matrices and the partition function of directed polymers on disordered trees, we show that for times $t>t_{\rm cr}$ (where $t_{\rm cr}$ is some critical time) a "lacunary" structure of the ultrametric space occurs with the probability $1-{\rm const}/t$. This means that the escape from some bounded areas of the ultrametric space of states is locked and the kinetics is confined in these areas for infinitely long time.

description: Since language is an integral part of a culture, inspecting linguistic expressions can unveil the hidden cultural memes of a society, conceptualized as cultuling (culture in language) analysis. The present study examined the cultuling of ‘making accreditation with English’ used by Persian native speakers from the upper, middle, and lower social classes. To this end, 623 pieces of natural utterances, embracing this cultuling, were extracted from people\\\'s conversations in public and private places and from Iranian movies. Then, 279 utterances were analyzed from linguistic, cultural, and psychological perspectives based on the cultuling analysis (CLA) model. Additionally, more data were acquired through semi-structured interviews with 198 participants aged 19 to 54. The results of the study revealed that Iranians use English for various purposes in their conversations, including accreditation, power, education, superior identity, and higher social class in public/ private and formal/ informal contexts. Moreover, the analysis of Iranians’ different reactions to hearing English words in conversations manifested their hidden cultural patterns, including indirectness, power distance, uncertainty avoidance, high context, collectivism, low trust, and overstating.

description: QCD amplitudes display a universal behaviour when one or more partons are soft and/or collinear. This can expressed in terms of antenna functions which are much simpler than the full amplitudes and yet correctly embody their infrared behaviour. We show how antenna functions can be naturally obtained via a twistor-inspired MHV approach. As an application, we present compact results for MHV and NMHV antennas functions valid for any number of gluons. These are sufficient to calculate the complete set of tree-level gluon antenna functions up to NNNLO. As an interesting corollary, we prove that splitting amplitudes too can be written directly through a MHV diagrammatic approach. Finally we find that antenna functions, collinear splitting amplitudes and eikonal factors satisfy the same kind of recursive relation as the full amplitudes.

Development of techniques for the supercritical fluid extraction of oils
Creators: name: Campbell, Hamish D
Publisher: name: University of British Columbia

description: Experimental equipment, procedures and an analysis method have been developed to provide equilibrium data for supercritical fluid solvents CO₂, C₂H₄, C₂H₆, C₃H₆ and C₃H₈ in tne presence of a multicomponent separator oil. The equilibrium cell was developed around a 1 dm³ high pressure autoclave. The maximum pressure and temperature ratings of the developed cell were 34.5 MPa and 200°C respectively. A circulating system was used in the design of the cell to allow the sampling of two fluid phases at isobaric equilibrium conditions. The high pressure samples were expanded to ambient conditions forming a liquid and gas phase. The liquid phase represents the oil fraction and the gas phase the solvent fraction. The oil analysis was based on a gas chromatographic distillation. The chromatographic analyses provided a qualitative and quantitative description of compounds with molecular weights up to n-C₃₉H₈₀. No gas analysis was performed and therefore the procedures were unsuitable for hydrocarbons more volatile than decane (n-CO₁₀H₂₂). The reliability of the present equipment and procedures were checked by comparing equilibrium data for the CO₂/n-CO₁₀H₂₂ system, obtained at a pressure of 10.34 MPa and a temperature of 137.8°C, with previously published data. Repeatability tests were also performed using supercritical CO₂ and a multicomponent oil solute at pressures of 13.5 MPa and 20.2 MPa at a temperature of 65.5°C.

description: There is increasing interest in identifying changes in the underlying states of brain networks. The availability of large scale neuroimaging data creates a strong need to develop fast, scalable methods for detecting and localizing in time such changes and also identify their drivers, thus enabling neuroscientists to hypothesize about potential mechanisms. This paper presents a fast method for detecting break points in exceedingly long time series neuroimaging data, based on vector autoregressive (Granger causal) models. It uses a multi-step strategy based on a regularized objective function that leads to fast identification of candidate break points, followed by clustering steps to select the final set of break points and subsequent estimation with false positives control of the underlying Granger causal networks. The latter provides insights into key changes in network connectivity that led to the presence of break points. The proposed methodology is illustrated on synthetic data varying in their length, dimensionality, number of break points, strength of the signal, and also applied to EEG data related to visual tasks.

description: Multifractal analysis and extensive statistical tests are performed upon intraday minutely data within individual trading days for four stock market indexes (including HSI, SZSC, S&P500, and NASDAQ) to check whether the indexes (instead of the returns) possess multifractality. We find that the mass exponent $τ(q)$ is linear and the singularity $α(q)$ is close to 1 for all trading days and all indexes. Furthermore, we find strong evidence showing that the scaling behaviors of the original data sets cannot be distinguished from those of the shuffled time series. Hence, the so-called multifractality in the intraday stock market indexes is merely an illusion.

Polyolefin allylsilane cyclisations
Creators: name: Armstrong, Rosemary Joyce
Publisher: name: University of British Columbia
Year: 2010

description: A series of Lewis acid-catalysed polyolefin cyclisations were performed, and the effect of the trimethylsilyl moiety and an ester group on the cyclisations were examined. It was found that an allylsilane not only directs formation of the resulting alkene to the less stable exocyclic position, but also activates an αβ-unsaturated ester in the cyclisation reactions. The allylsilanes 138 and 172 were synthesised and were treated with a variety of Lewis acids to give the monocyclic gem-dimethylcyclohexane 140 and the drimane 173b, respectively. The allylsilyl acid 123 was also synthesised and converted to structure 125. Elaboration of 140 and 125 into the monocyclic terpenoid, trixagol (153), and of 173b into several bicyclic terpenoids, albicanol (179b), albicanyl acetate (180), and isodrimenin (183), was achieved. The allylsilyl epoxides 191 and 226 were successfully synthesised and cyclised to the structures 189 and 229b, respectively. These are some of the first examples of an efficient cyclisation of an olefinic epoxide, and once again the trimethylsilyl group was found to be exceedingly useful in directing formation of the olefin to the exocyclic position. Karahana ether (193) was obtained in two steps from the cyclised product 189, and elaboration of 229b resulted in the first reported synthesis of 3-hydroxylabda-8(20),13-dien-15-oic acid (238).

description: We present an experiment that systematically probes the basins of attraction of two fixed points of a nonlinear nanomechanical resonator and maps them out with high resolution. We observe a separatrix which progressively alters shape for varying drive strength and changes the relative areas of the two basins of attraction. The observed separatrix is blurred due to ambient fluctuations, including residual noise in the drive system, which cause uncertainty in the preparation of an initial state close to the separatrix. We find a good agreement between the experimentally mapped and theoretically calculated basins of attraction.
The cardiac Ca-sensitive regulatory switch, a system in dynamic equilibrium

description: The Ca-sensitive regulatory switch of cardiac muscle is a paradigmatic example of protein assemblies that communicate ligand binding through allosteric change. The switch is a dimeric complex of troponin C (TnC), an allosteric sensor for Ca, and troponin I (TnI), an allosteric reporter. Time-resolved equilibrium FRET measurements suggest that the switch activates in two steps: a TnI-independent Ca-priming step followed by TnI-dependent opening. To resolve the mechanistic role of TnI in activation we performed stopped-flow FRET measurements of activation following rapid addition of a lacking component (Ca or TnI) and deactivation following rapid chelation of Ca. The time-resolved measurements, stopped-flow measurements, and Ca-titration measurements were globally analyzed in terms of a new quantitative dynamic model of TnC-TnI allostery. The analysis provided a mesoscopic parameterization of distance changes, free energy changes, and transition rates among the accessible coarse-grained states of the system. The results reveal (i) the Ca-induced priming step, which precedes opening, is the rate limiting step in activation, (ii) closing is the rate limiting step in deactivation, (iii) TnI induces opening, (iv) an incompletely deactivated population when regulatory Ca is not bound, which generates an accessory pathway of activation, and (v) incomplete activation by Ca--when regulatory Ca is bound, a 3:2 mixture of dynamically inter-converting open (active) and primed-closed (partially active) conformers is observed (15 C). Temperature-dependent stopped-flow FRET experiments provide a near complete thermo-kinetic parametrization of opening.

description: A simulation tool which utilizes parallel processing is developed to describe molecular kinetics in 2D, single-and multi-component atmospheres on Callisto. This expands on our previous study on the role of collisions in 1D atmospheres on Callisto composed of radiolytic products (Carberry Mogan et al., 2020) by implementing a temperature gradient from noon to midnight across Callisto's surface and introducing sublimated water vapor. We compare single-species, ballistic and collisional O2, H2 and H2O atmospheres, as well as an O2+H2O atmosphere to 3-species atmospheres which contain H2 in varying amounts. Because the H2O vapor pressure is extremely sensitive to the surface temperatures, the density drops several order of magnitude with increasing distance from the subsolar point, and the flow transitions from collisional to ballistic accordingly. In an O2+H2O atmosphere the local temperatures are determined by H2O near the subsolar point and transition with increasing distance from the subsolar point to being determined by O2 When radiolytically produced H2 is not negligible in O2+H2O+H2 atmospheres, this much lighter molecule, with a scale height roughly an order of magnitude larger than that for the heavier species, can cool the local temperatures via collisions. In addition, if the H2 component is dense enough, particles originating on the day-side and precipitating into the night-side atmosphere deposit energy via collisions, which in turn heats the local atmosphere relative to the surface temperature. Finally, we discuss the potential implications of this study on the presence of H2 in Callisto's atmosphere and how the simulated densities correlate with expected detection thresholds at flyby altitudes of the proposed JUpiter ICy moons Explorer (JUICE) spacecraft.

description: Time-sharing Experiments for the Social Sciences (TESS) offers researchers the opportunity to capture the internal validity of experiments. Investigators submit proposals, and TESS fields successful proposals for free on a representative sample of adults in the United States. This experiment was conducted to examine whether the perceived purpose of college differs across social class backgrounds, college financing arrangements, and gender. Respondents were randomly assigned to read one of twelve vignettes about a student who is graduating from high school and will attend college. Vignettes vary students’ social class background, gender, and how they will pay for college. A total of 1,610 respondents participated. Respondents were asked to rate how likely they would be to recommend different college majors for the student and to rank different academic and social experiences in order of importance for the student. This allowed for comparison of believes about the purpose of college across different types of students.
Comparative study of a solid film dewetting in an attractive substrate potentials with the exponential and the algebraic decay

Publisher: name: arXiv
Year: 2008
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We compare dewetting characteristics of a thin nonwetting solid film in the absence of stress, for two models of a wetting potential: the exponential and the algebraic. The exponential model is a one-parameter (r) model, and the algebraic model is a two-parameter (r,m) model, where r is the ratio of the characteristic wetting length to the height of the unperturbed film, and m is the exponent of h (film height) in a smooth function that interpolates the system's surface energy above and below the film-substrate interface at z=0. The exponential model gives monotonically decreasing (with h) wetting chemical potential, while this dependence is monotonic only for the m=1 case of the algebraic model. Linear stability analysis of the planar equilibrium surface is performed. Simulations of the surface dynamics in the strongly nonlinear regime (large deviations from the planar equilibrium) and for large surface energy anisotropies demonstrate that for any m the film is less prone to dewetting when it is governed by the algebraic model. Quasiequilibrium states similar to the one found in the exponential model (M. Khenner, Phys. Rev. B 77, 245445 (2008)) exist in the algebraic model as well, and the film morphologies are similar.

description: Using quantum Monte Carlo simulations, we study a mixture of bosons and fermions loaded on an optical lattice. With simple on-site repulsive interactions, this system can be driven into a solid phase. We dope this phase and, in analogy with pure bosonic systems, identify the conditions under which the bosons enter a supersolid phase, i.e., exhibiting at the same time charge density wave and superfluid order. We perform finite size scaling analysis to confirm the presence of a supersolid phase and discuss its properties, showing that it is a collective phase that also involve phase coherence of the fermions.
