description: The first set of theoretical cross sections for propylene oxide (CH3CHCH2O) colliding with cold He atoms has been obtained at the full quantum level using a high-accuracy potential energy surface. By scaling the collision reduced mass, rotational rate coefficients for collisions with para-H2 are deduced in the temperature range 5-30 K. These collisional coefficients are combined with radiative data in a non-LTE radiative transfer model in order to reproduce observations of propylene oxide made towards the Sagittarius B2(N) molecular cloud with the Green Bank and Parkes radio telescopes. The three detected absorption lines are found to probe the cold (~ 10 K) and translucent (nH ~ 2000 cm-3) gas in the outer edges of the extended Sgr B2(N) envelope. The derived column density for propylene oxide is Ntot ~ 3e12 cm-2, corresponding to a fractional abundance relative to total hydrogen of ~ 2.5e-11. The present results are expected to help our understanding of the chemistry of propylene oxide, including a potential enantiomeric excess, in the cold interstellar medium.

description: The constellation of Earth-observing satellites continuously collects measurements of scattered radiance, which must be transformed into geophysical parameters in order to answer fundamental scientific questions about the Earth. Retrieval of these parameters requires highly flexible, accurate, and fast forward and inverse radiative transfer models. Existing forward models used by the remote sensing community are typically accurate and fast, but sacrifice flexibility by assuming the atmosphere or ocean is composed of plane-parallel layers. Monte Carlo forward models can handle more complex scenarios such as 3D spatial heterogeneity, but are relatively slower. We propose looking to the computer graphics community for inspiration to improve the statistical efficiency of Monte Carlo forward models and explore new approaches to inverse models for remote sensing. In Part 1 of this work, we examine the evolution of radiative transfer models in computer graphics and highlight recent advancements that have the potential to push forward models in remote sensing beyond their current periphery of realism.

description: We present a novel approach to derive the age of very young star clusters, by using the Turn-On (TOn). The TOn is the point in the color-magnitude diagram (CMD) where the pre-main sequence (PMS) joins the main sequence (MS). In the MS luminosity function (LF) of the cluster, the TOn is identified as a peak followed by a dip. We propose that by combining the CMD analysis with the monitoring of the spatial distribution of MS stars it is possible to reliably identify the TOn in extragalactic star forming regions. Compared to alternative methods, this technique is complementary to the turn-off dating and avoids the systematic biases affecting the PMS phase. We describe the method and its uncertainties, and apply it to the star forming region NGC346, which has been extensively imaged with the Hubble Space Telescope (HST). This study extends the LF approach in crowded extragalactic regions and opens the way for future studies with HST/WFC3, JWST and from the ground with adaptive optics.

The mass spectra of hidden-charm hexaquark states are obtained within the chromo-magnetic interaction model. In addition to the mass spectra analysis, we further illustrate their two-body strong decay behaviors. There exist some compact bound states which cannot decay through the strong interaction. Hopefully our results will help to search for such types of the exotic states in the future experiments.

description: Thanks to high sensitivity and angular resolution and broad spectral coverage, SPICA will offer a unique opportunity to better characterize the nature of polycyclic aromatic hydrocarbons (PAHs) and very small grains (VSGs), to better use them as probes of astrophysical environments. The angular resolution will enable to probe the chemical frontiers in the evolution process from VSGs to neutral PAHs, to ionized PAHs and to "Grand-PAHs" in photodissotiation regions and HII regions, as a function of G$_0$/n (UV radiation field / density). High sensitivity will favor the detection of the far-IR skeletal emission bands of PAHs, which provide specific fingerprints and could lead to the identification of individual PAHs. This overall characterization will allow to use PAH and VSG populations as tracers of physical conditions in spatially resolved protoplanetary disks and nearby galaxies (using mid-IR instruments), and in high redshift galaxies (using the far-IR instrument), thanks to the broad spectral coverage SPICA provides. Based on our previous experience with ISO and Spitzer we discuss how these goals can be reached.

description: Axion-like particles (ALPs) interacting with the Standard Model can be abundantly produced in proton beam fixed-target experiments. Looking for their displaced decays is therefore an effective search strategy for ALPs with a mass in the MeV to GeV range. Focusing on the benchmark models where the ALP interacts dominantly with photons or gluons, we show that the proposed DarkQuest experiment at Fermilab will be able to test parameter space which has been previously inaccessible. We pay particular attention to the self-consistency of gluon-coupled ALP production and decay calculations, which has been recently shown to be a problem in many existing predictions. We also apply these results to explore existing constraints in the ALP parameter space.

Extreme value statistics and arcsine laws for heterogeneous diffusion processes
Creators: name: Singh, Prashant
Publisher: name: arXiv
Year: 2021
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Heterogeneous diffusion with spatially changing diffusion coefficient arises in many experimental systems like protein dynamics in the cell cytoplasm, mobility of cajal bodies and confined hard-sphere fluids. Here, we showcase a simple model of heterogeneous diffusion where the diffusion coefficient $D(x)$ varies in power-law way, i.e. $D(x) \sim |x|^{-α}$ with the exponent $α>-1$. This model is known to exhibit anomalous scaling of the mean squared displacement (MSD) of the form $\sim t^{\frac{2}{2+α}}$ and weak ergodicity breaking in the sense that ensemble averaged and time averaged MSDs do not converge. In this paper, we look at the extreme value statistics of this model and derive, for all $α$, the exact probability distributions of the maximum spatial displacement $M(t)$ and arg-maximum $t_m(t)$ (i.e. the time at which this maximum is reached) till duration $t$. In the second part of our paper, we analyze the statistical properties of the residence time $t_r(t)$ and the last-passage time $t_{\ell}(t)$ and compute their distributions exactly for all values of $α$. Our study unravels that the heterogeneous version $(α\neq 0)$ displays many rich and contrasting features compared to that of the standard Brownian motion (BM). For example, while for BM $(α=0)$, the distributions of $t_m(t),~t_r(t)$ and $t_{\ell}(t)$ are all identical (\textit{á la} "arcsine laws" due to Lévy), they turn out to be significantly different for non-zero $α$. Another interesting property of $t_r(t)$ is the existence of a critical $α$ (which we denote by $α_c=-0.3182$) such that the distribution exhibits a local maximum at $t_r = t/2$ for $α< α_c$

description: Controlling quantum materials with light is of fundamental and technological importance. By utilizing the strong coupling of light and matter in optical cavities1?3, recent studies were able to modify some of their most defining features4?6. Here we study the magneto-optical properties of a van der Waals magnet that supports strong coupling of photons and excitons even in the absence of external cavity mirrors. In this material?the layered magnetic semiconductor CrSBr?emergent light?matter hybrids called polaritons are shown to substantially increase the spectral bandwidth of correlations between the magnetic, electronic and optical properties, enabling largely tunable optical responses to applied magnetic fields and magnons. Our results highlight the importance of exciton?photon self-hybridization in van der Waals magnets and motivate novel directions for the manipulation of quantum material properties by strong light?matter coupling.

description: The 5$d$ transition metal oxides, in particular iridates, host novel electronic and magnetic phases due to the interplay between onsite Coulomb repulsion ($U$) and spin-orbit coupling (SOC). The reduced dimensionality brings another degree of freedom to increase the functionality of these systems. By taking the example of ultrathin films of SrIrO$_3$,theoretically, we demonstrate that confinement led localization can introduce large magnetic anisotropy energy (MAE) in the range 2-7 meV/Ir which is one to two orders higher than that of the traditional MAE compounds formed out of transition metals and their multilayers. Furthermore, in the weak correlation limit, tailored terminations can yield multiple Dirac states across a large energy window of 2 eV around the Fermi energy which is a rare phenomena in correlated oxides and upon experimental realization it will give rise to unique transport properties with excitation and doping.
A simple model to link the properties of quasars to the properties of dark matter halos out to high redshift

description: We present a simple model of how quasars occupy dark matter halos from z=0 to z=5 using the observed mBH-sigma relation and quasar luminosity functions. This provides a way for observers to statistically infer host halo masses for quasar observations using luminosity and redshift alone. Our model is deliberately simple and sidesteps any need to explicitly describe the physics. In spite of its simplicity, the model reproduces many key observations and has predictive power: 1) model quasars have the correct luminosity function (by construction) and spatial clustering (by consequence); 2) we predict high redshift quasars of a given luminosity live in less massive dark matter halos than the same luminosity quasars at low redshifts; 3) we predict a factor of ~5 more 10^8.5Msun black holes at z~2 than is currently observed; 4) we predict a factor of ~20 evolution in the amplitude of the mBH-Mhalo relation between z=5 and the present day; 5) we expect luminosity dependent quasar lifetimes of between tQ~10^(7-8)yr, but which may become as short as 10^(5-6)yr for quasars brighter than L*; 6) while little luminosity dependent clustering evolution is expected at z<1, increasingly strong evolution is predicted for L>L* quasars at higher redshifts. These last two results arise from the narrowing distribution of halo masses that quasars occupy as the Universe ages. We also deconstruct both "downsizing" and "upsizing" trends predicted by the model at different redshifts and space densities. Importantly, this work illustrates how current observations cannot distinguish between more complicated physically motivated quasar models and our simple phenomenological approach. It highlights the opportunities such methodologies provide.

Depth-resolved OCT reveals unique features of retinal arteries and veins. Retinal arteries show hyper-reflective boundaries at both upper (inner side towards the vitreous) and lower (outer side towards the choroid) walls. In contrary, retinal veins reveal hyper-reflectivity at the upper boundary only. Uniform lumen intensity was observed in both small and large arteries. However, the vein lumen intensity was dependent on the vessel size. Small veins exhibit a hyper-reflective zone at the bottom half of the lumen, while large veins show a hypo-reflective zone at the bottom half of the lumen

Consolidation of sand formation using Freon-11 gas hydrate
Creators: name: Cheng, Wai Keung
Publisher: name: University of British Columbia
Year: 2010

description: In this study, the conditions under which gas hydrates form in a porous sand formation were explored. It was established that the permeability of the sand may be greatly reduced by the gas hydrate crystals formed in the pores. Freon-11 gas hydrate was formed in a two-inch sand bed in a high pressure vessel of one-inch diameter under isothermal condition.. Hydrate was found to have been formed in the pores of sand beds of four ranges of particle sizes from 24 mesh to 60 mesh. Laboratory tests showed that the hydrate thus formed could sustain a hydraulic pressure of 1000 psia across the two-inch bed. A subcooling of about 5°C was required for the hydrate to form in sand pores and eliminate its permeability. The hydrate melted at its critical temperature which was higher than its nucleation temperature. The time required for the hydrate crystal to grow to a size large enough to block the pores of the bed was about two hours. In practice, this would allow sufficient time for the hydrate forming agent to be forced to a large area from one injection point. The amount of hydrate forming agent required to block the sand pores was found to be approximately that calculated from the ideal composition of the hydrate. The result of this study shows that the hydrate formation process in pores of a sand bed behaved as predicted by the thermodynamic properties of the hydrate. Thus, although only Freon-11 gas hydrate was used in this study, any other hydrate former or mixture of hydrate formers may be selected for this use if their thermodynamic properties match the conditions in the porous formation.

description: We theoretically study emergent edge and corner states in monolayer blue phosphorus (blue phosphorene) using the first-principles calculation and tight-binding model. We show that the existence of the Wannier orbitals at every bond center yields edge states both in zigzag and armchair nanoribbons. The properties of the edge states can be well described by a simple effective Hamiltonian for uncoupled edge orbitals, where the structural relaxation near the boundary significantly affects the edge band structure. For corner states, we examine two types of corner structures consisting of zigzag and armchair edges, where we find that multiple corner states emerge in the bulk gap as a consequence of hybridization of edge and corner uncoupled orbitals. In the armchair corner, in particular, we demonstrate that corner states appear right at the Fermi energy, which leads to the emergence of fractional corner charge due to filling anomaly. Finally, we discuss the relationship between blue phosphorene and black phosphorene, and show that two systems share the equivalent Wannier orbital positions and similar edge/corner state properties even though their atomic structures are totally different.

description: Recent advances in topological artificial systems open the door to realizing topological states in dimensions higher than the usual three-dimensional space. Here, we present a "tensor product" theory, which offers a method to construct Chern insulators with arbitrarily high dimensions and Chern numbers. Particularly, we show that the tensor product of a $d_A$D Chern insulator $\langle \mathcal{H}_A^{(κ_{A})}, C_A\rangle$ with a $d_B$D Chern insulator $\langle \mathcal{H}_B^{(κ_B)}, C_B\rangle$ leads to a $(d_A+d_B)$D Chern insulator $\langle \mathcal{H}_{A B}^{(κ_A\star κ_B)},-2C_AC_B\rangle $, where in the brackets, $\mathcal{H}^{(κ)}$ is the $d$D Hamiltonian with $d$ even, $C$ is the corresponding $(d/2)$th Chern number, and $κ$ labels the five non-chiral Altland-Zirnbauer symmetry classes A, AI, D, AII and C. The four real classes AI, D, AII and C form a Klein four-group under the multiplication `$\star$' with class AI the identity, and class A is the zero element. Our theory leads to novel higher-dimensional topological physics. (i) The construction can generate large higher-order Chern numbers, e.g., for some cases the resultant classification is $8\mathbb{Z}$. (ii) Fascinatingly, the boundary states feature flat nodal hypersurfaces with nontrivial Chern charges. For the constructed $(d_A+d_B)$D Chern insulator, a boundary perpendicular to a direction of $\mathcal{H}_A$ generically hosts $|C_A|$ $d_B$D nodal hypersurfaces, each of which has topological charge $\pm 2C_B$. Under perturbations, each nodal hypersurface bursts into stable unit nodal points, with the total Chern charge conserved. Examples are given to demonstrate our theory, which can be experimentally realized in artificial systems such as acoustic crystals, electric circuit arrays, ultracold atoms, or mechanical networks.

An alternative B cell development program

Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2008
Subjects: BIO/17 Istologia

description: Two major types of B cells, the antibody-producing cells of the immune
system, are classically distinguished in the spleen: marginal zone (MZ) and
follicular (FO). In addition, FO B cells are subdivided into FO I and FO II
cells, based on the amount of surface IgM. MZ B cells, which surround the
splenic follicles, rapidly produce IgM in response to blood-borne pathogens
without T cell help, while T cell-dependent production of high affinity,
isotype-switched antibodies is ascribed to FO I cells. The significance of FO
II cells and the mechanism underlying B cell fate choices are unclear. We
showed that FO II cells express more Sca1 than FO I cells and originate
from a distinct B cell development program, marked by high expression of
Sca1. MZ B cells can derive from the “canonical” Sca1lo pathways, as well
as from the Sca1hi program, although the Sca1hi program shows a stronger
MZ bias than the Sca1lo program, and extensive phenotypic plasticity exists
between MZ and FO II, but not between MZ and FO I cells. The Sca1hi
program is induced by hematopoietic stress and generates B cells with an
Igλ-enriched repertoire. In aged mice, the canonical B cell development
pathway is impaired, while the Sca1hi program is increased. Furthermore, we
showed that a population of unknown function, defined as Lin-c-kit+Sca1+
(LSK-), contains early lymphoid precursors, with primarily B cell potential
in vivo. Our data suggest that LSK- cells may represent a distinct precursor
for the Sca1hi program in the bone marrow.

description: We evaluate the Casimir energy and force for a massive fermionic field in the geometry of two parallel plates on background of Minkowski spacetime with an arbitrary number of toroidally compactified spatial dimensions. The bag boundary conditions are imposed on the plates and periodicity conditions with arbitrary phases are considered along the compact dimensions. The Casimir energy is decomposed into purely topological, single plate and interaction parts. With independence of the lengths of the compact dimensions and the phases in the periodicity conditions, the interaction part of the Casimir energy is always negative. In order to obtain the resulting force, the contributions from both sides of the plates must be taken into account. Then, the forces coming from the topological parts of the vacuum energy cancel out and only the interaction term contributes to the Casimir force. Applications of the general formulae to Kaluza-Klein type models and carbon nanotubes are given. In particular, we show that for finite length metallic nanotubes the Casimir forces acting on the tube edges are always attractive, whereas for semiconducting-type ones they are attractive for small lengths of the nanotube and repulsive for large lengths.

Scienza sociale o politica? Il dilemma dell’avalutatività
Creators: name: Fitzi, Gregor
Publisher: name: Università degli Studi di Firenze
Year: 2014

description: The rapid growth of the ‘studies’ profoundly influenced the social sciences in recent decades. Against the background of this reality, to ask today the question of Weber’s value neutrality appears an anachronism. The relationship between science, ethics and politics is characterized today by a massive blending of communicative codes. Political intentions and ethical principles guide the main stream of social science. The essay reconstructs the fundamental features of Weber’s conception of the conduct of life of the scientist and the political and highlights its normative intent. For Weber the functional differentiation between the spheres of science, ethics and politics is not only an achievement of modernity, but also an ethical-political heritage to defend. Weber only spends a few words about the background of this position. By comparison with Luhmann’s theory of ‘human rights as a social institution’ the essay offers a key to interpreting the position of Weber and its consequences for an analysis of the current success of the studies.

description: Let $\mathcal{D}=(d_n)_{n=1}^\infty$ be a bounded sequence of integers with $d_n\ge 2$ and let $(i, j)$ be a pair of strictly positive numbers with $i+j=1$. We prove that the set of $x \in \RR$ for which there exists some constant $c(x) > 0$ such that \[ \max\{|q|_\DDD^{1/i}, \|qx\|^{1/j}\} > c(x)/ q \qquad \forall q \in \NN \] is one quarter winning (in the sense of Schmidt games). Thus the intersection of any countable number of such sets is of full dimension. In turn, this establishes the natural analogue of Schmidt's conjecture within the framework of the de Mathan-Teulié conjecture -- also known as the `Mixed Littlewood Conjecture'.

description: Photonic states encoded in spatial modes of paraxial light fields provide a promising platform for high-dimensional quantum information protocols and related studies, where several pioneering theoretical and experimental demonstrations have paved the path for future technologies. Crucially, critical issues encountered in free-space propagation still represent a major challenge. This is the case of asynchronous diffraction between spatial modes with different modal orders, which experience variations in their transverse structure upon free-space propagation. Here we address this issue by proposing an encoding method based on the use of Laguerre-Gaussian (LG) modes of the same modal order N to define a N + 1 dimensional space. Noteworthy, such modes endowed with orbital angular momentum (OAM) experience the same propagation aberrations featuring an identical Gouy phase and wavefront curvature. We demonstrate our proposal experimentally by using time-correlated-single-photon imaging combined with a digital propagation technique. Importantly, our technique allows to eliminate, without the use of imaging systems, all issues related to asynchronous diffraction, providing an accessible way to generate propagation-invariant OAM qudits for quantum optical protocols.
Squark Flavor Violation at the LHC

description: We consider the prospects for measuring squark flavor violation through the signal of single top production at the LHC. We study this signal in the context of R-symmetric supersymmetry, which allows for large flavor violation in the squark sector, however the results can also be generalized to the MSSM. The single top signal arises from squark pair production in which one squark decays to a top and gaugino, whereas the other squark decays to a non-top quark and gaugino. We study three decay patterns: (I) squark decay into a quark and neutralino LSP; (II) squark decay into a quark and neutralino NLSP, with subsequent decay of the NLSP to a photon and gravitino; (III) squark decay into a quark and chargino NLSP, with subsequent decay of the NLSP to a H^\pm/W^\pm and gravitino. Case II is the most promising, when the NLSP decay is prompt, since every event contains two hard photons that can be used to tag the events, reducing the background to a negligible level. Case I is promising if the neutralino LSP is bino-like. We carefully consider large SM backgrounds and identify a series of cuts to isolate the signal. Case III can occur in the MRSSM with Higgsino-like lightest gauginos. Due to the large Higgs coupling, squarks preferentially decay to top quarks, substantially reducing the potential flavor violating signal. Nevertheless, the flavor violating signal might still be identifiable if the chargino NLSP is long-lived.

Law and Science through the Lens of Patent Law and Software Agents

description: In this investigation I look at patents and software agents as a way to study broader relation between law and science (the latter term broadly understood as inclusive of science and technology). The overall premise framing the entire discussion, my basic thesis, is that this relation, between law and science, cannot be understood without taking into account a number of intervening factors identifying which makes it necessary to approach the question from the standpoint of fields and disciplines other than law and science themselves.

Protection Strategy of Sensitive Body Organs in Radiation Therapy

description: In this paper, we investigate protection strategies of sensitive body anatomy against the irradiation to the cancerous moving tumors in intensity modulated radiation therapy. Inspired by optimization techniques developed in statistical physics and dynamical systems, we deploy a method based on variational principles and formulate an efficient genetic algorithm which enable us to search for global minima in a complex landscape of irradiation dose delivered to the radiosensitive organs at risk. We take advantage of the internal motion of body anatomy during radiation therapy to reduce the unintentional delivery of the radiation to sensitive organs. We show that the accurate optimization of the control parameters, compare to the conventional IMRT and widely used delivery based on static anatomy assumption, leads to a significant reduction of the dose delivered to the organs at risk.

The solution photochemistry of some Diels-Alder adducts
Creators: name: Ngan, Yuen Mui
Publisher: name: University of British Columbia

description: In order to extend the study of the photochemistry of substituted butadiene-α, β-unsaturated ketone Diels-Alder adducts, 3,4-dimethyl-3- cyclohexenyl phenyl ketone (47) and cis and trans-2,5-dimethyl-3-cyclo- hexenyl methyl ketone (48 and 56) were synthesized and photolyzed. The photoproducts from 3,4-dimethyl-3-cyclohexenyl phenyl ketone were obtained in very low yields with difficuclty, and appeared to have arisen via a hydrogen abstraction process. The photoreaction of cis-2,5-dimethyl-3- cyclohexenyl methyl ketone resulted in the formation of 8-oxa-2,5,7- trimethyltricyclo[4.2.0.0]³[sup ,]⁷]octane (80A), 7-oxa-2,5,8-trimethyltricyclo-3 8 [4.2.0.0]³[sup ,]⁸]octane (81B) and 7-hydroxy-4,7-dimethylbicyclo[4.2.0]oct-2-ene (82C) , all in low yield. The first two products were produced by an intramolecular Paterno-Buchi reaction, while the third was formed from a Norrish Type II reaction. Photolysis of trans-2,5-dimethyl-3-cyclo- hexenyl methyl ketone afforded the major product 7-oxa-3,6,8-trimethyl- bicyclo[3.2.1]oct-2-ene (83B) in low yield, for which a mechanism involving a diradical intermediate and an unusual intramolecular 1,4-hydrogen transfer was postulated. In addition the photochemistry of the trans-1,3,5-hexatriene- p-benzoquinone Diels-Alder adduct (t-59) was investigated. Selective n-π* excitation of this material led to a single product, tetracyclo[6.4.0. 2 11 4 9 0.²[sup ,]¹¹ 0⁴[sup ,]⁹ ]dodec-6-ene-3,10-dione (127) in high yield, the result of a novel regiospecific intramoleculat 2+2 photoaddition. A two step mechanism involving a diradical intermediate was proposed, and the observed photoreaction was discussed in terms of conformational and radical stability effects.
