description: We study the formation and collision-aided decay of an ultra-cold atomic Bose-Einstein condensate in the first excited band of a double-well 2D-optical lattice with weak harmonic confinement in the perpendicular $z$ direction. This lattice geometry is based on an experiment by Wirth et al. The double well is asymmetric, with the local ground state in the shallow well nearly degenerate with the first excited state of the adjacent deep well. We compare the band structure obtained from a tight-binding (TB) model with that obtained numerically using a plane wave basis. We find the TB model to be in quantitative agreement for the lowest two bands, qualitative for next two bands, and inadequate for even higher bands. The band widths of the excited bands are much larger than the harmonic oscillator energy spacing in the $z$ direction. We then study the thermodynamics of a non-interacting Bose gas in the first excited band. We estimate the condensate fraction and critical temperature, $T_c$, as functions of lattice parameters. For typical atom numbers, the critical energy $k_BT_c$, with $k_B$ the Boltzmann constant, is larger than the excited band widths and harmonic oscillator energy. Using conservation of total energy and atom number, we show that the temperature increases after the lattice transformation. Finally, we estimate the time scale for a two-body collision-aided decay of the condensate as a function of lattice parameters. The decay involves two processes, the dominant one in which both colliding atoms decay to the ground band, and the second involving excitation of one atom to a higher band. For this estimate, we have used TB wave functions for the lowest four bands, and numerical estimates for higher bands. The decay rate rapidly increases with lattice depth, but stays smaller than the tunneling rate between the $s$ and $p$ orbitals in adjacent wells.

description: A revision of the Heirtzler and others magnetic reversal time scale is presented. In addition to incorporating published studies which have increased the resolution and accuracy of their time scale, we have revised the relative lengths of anomalies 4A to 5 and 29 to 34 and have eliminated anomaly 14. We have calibrated the time scale by choosing an age of 3.32 m.y. B.P. for the older reversal boundary of anomaly 2A and 64.9 m.y. B.P. for the older reversal boundary of anomaly 29. The resulting magnetic reversal time scale is in reasonable agreement with the biostratigraphic ages from Deep Sea Drilling Project (DSDP) drill holes.

description: X-ray computed tomography at the nanometer scale (nano-CT) offers a wide range of applications in scientific and industrial areas. Here we describe a reliable, user-friendly and fast software package based on LabVIEW that may allow to perform all procedures after the acquisition of raw projection images in order to obtain the inner structure of the investigated sample. A suitable image alignment process to address misalignment problems among image series due to mechanical manufacturing errors, thermal expansion and other external factors has been considered together with a novel fast parallel beam 3D reconstruction procedure, developed ad hoc to perform the tomographic reconstruction. Remarkably improved reconstruction results obtained at the Beijing Synchrotron Radiation Facility after the image calibration confirmed the fundamental role of this image alignment procedure that minimizes unwanted blurs and additional streaking artifacts always present in reconstructed slices. Moreover, this nano-CT image alignment and its associated 3D reconstruction procedure fully based on LabVIEW routines, significantly reduce the data post-processing cycle, thus making faster and easier the activity of the users during experimental runs.

Sympathetic cooling of fluorine atoms with ultracold atomic hydrogen

description: We consider the prospect of using ultracold hydrogen atoms for sympathetic cooling of fluorine atoms to microkelvin temperatures. We carry out quantum-mechanical calculations on collisions between cold F and H atoms in magnetically trappable states and show that the ratio of elastic to inelastic cross sections remains high across a wide range of temperatures and magnetic fields. For F atoms initially in the spin-stretched state ($^2$P$_{3/2}$, $f=m_f=+2$), sympathetic cooling appears likely to succeed from starting temperatures around 1 K or even higher. This occurs because inelastic collisions are suppressed by p-wave and d-wave barriers that are 600 mK and 3.2 K high, respectively. In combination with recent results on H + NH and H + OH collisions [M. L. González-Mart\'ınez and J. M. Hutson, arXiv:1305.6282 (2013)], this establishes ultracold H atoms as a very promising and versatile coolant for atoms and molecules that cannot be laser-cooled.

description: Preliminary paleomagnetic study of granitic and sedimentary rocks from the Ellsworth-Whitmore Mountains crustal block (EVH), Vest Antarctica, leads to the following conclusions: (1) The EVH has a paleogole for the Middle Jurassic located at 235°E, 41°S, (α₉₅ = 5.3, N = 8 sites) assuming that no widespread regional tilting has occurred since the magnetization measured was acquired. A Middle Jurassic paleolatitude of 47°S is indicated for the sites and precludes an original location for the EVH block south of the Antarctic Peninsula crustal block (AP). (2) This pole is not significantly different from the previously published Middle Jurassic paleopole obtained from rocks of the northern Antarctic Peninsula. The combined AP-EVH paleopole, compared to the Middle Jurassic mean paleopole obtained from igneous rocks of the Ferrar Supergroup in East Antarctica, suggests about 15° tectonic clockwise rotation of the AP and EVH. Since the AP and EVH poles coincide, these two crustal blocks may have moved as one unit since the Middle Jurassic. ( 3) The new data are compatible with two different Gondwanaland reconstructions. The first considers the AP and EVH as separate entities. The second is based on the movement of the AP and EVH as one block. For the Middle Jurassic, both reconstructions would locate the EVH west of Coats Land and south of the Falkland Plateau, with the adjacent AP located south of southernmost South America. (4) Enigmas concerning the structural trend and isolation of the thick Ellsworth Mountains Paleozoic succession persist.

description: We study intertwining relations for matrix one-dimensional, in general, non-Hermitian Hamiltonians by matrix differential operators of arbitrary order. It is established that for any matrix intertwining operator Q_N^- of minimal order N there is a matrix operator Q_{N'}^+ of different, in general, order N' that intertwines the same Hamiltonians as Q_N^- in the opposite direction and such that the products Q_{N'}^+Q_N^- and Q_N^-Q_{N'}^+ are identical polynomials of the corresponding Hamiltonians. The related polynomial algebra of supersymmetry is constructed. The problems of minimization and of reducibility of a matrix intertwining operator are considered and the criteria of minimizability and of reducibility are presented. It is shown that there are absolutely irreducible matrix intertwining operators, in contrast to the scalar case.

title: Characterization of Atlantic salmon head kidney leukocyte culture
Creators: name: Smith, Nicole C.
Publisher: name: Memorial University of Newfoundland

description: The Atlantic salmon (Salmo salar) is an economically important farmed and wild fish in several countries including Canada. Macrophages are white blood cells of the immune system of fish and other vertebrates, that are essential in fighting infection and disease. Elucidating how macrophages differentiate and function is necessary to fully understand how the fish immune system functions and to enable the development of methods to maintain healthy fish. Therefore, the objective of my Ph.D. thesis was to characterize the Atlantic salmon adherent head kidney leukocyte (HKL) culture, a macrophage-like model commonly used in fish immunological studies, using various genomic and complementary techniques. Using morphology (Giemsa stain) and functional (phagocytosis) assays, the results of this thesis showed that the Atlantic salmon adherent HKL population changes during culture time. At Day 1 of culture, the results suggest that adherent HKLs are a heterogeneous population of predominantly “monocyte-like”, cells but by Day 5 of culture, the cells become more homogenous selectively enriched with macrophages. RNA-sequencing identified a change in the microRNA (miRNA) profile of Day 1 and Day 5 adherent HKLs, as well as the extracellular vesciles (EVs) released from them. Many of the identified miRNAs are involved in macrophage function and/or differentiation in other species. Furthermore, using a 44K microarray, changes in the mRNA transciprtome were profiled. Macrophage-related transcripts, lipid-related transcripts, immune-related transcripts and transcription factors were identified as differentially expressed between the two cell populations. In addition, GO term enrichment and network analysis identified immune-related and immune-cell differentiation related terms. The results of this thesis provides evidence that the Atlantic salmon HKL culture changes to become predominantly “macrophage-like” by Day 5 of culture and this is something that should be kept in mind when using HKLs for in vitro fish immunology studies. This research provides novel insight into the genes, miRNAs and molecular pathways involved in the differentiation of Atlantic salmon adherent HKLs from monocyte-like cells to macrophage-like cells.
Magnetic polarity stratigraphy and paleolatitude of the Triassic-Jurassic Blomidon Formation in the Fundy basin (Canada): implications for early Mesozoic tropical climate gradients
Creators: name: Kent, Dennis V.

Subjects: Paleoclimatology

description: A magnetic polarity stratigraphy is established for a continuously cored 360 m thick section of the entire cyclical lacustrine sequence and part of the sandy fluvial and eolian basal sequence of the Late Triassic Blomidon Formation in the Fundy basin in Nova Scotia (Canada). In conjunction with published results for the Newark and Dan River basins, the Fundy basin record allows us to precisely map the spatio-temporal distribution of climate-sensitive continental lithofacies along a paleolatitudinal transect in eastern North America corresponding to the tropics of Pangea in the Late Triassic. Indicators of high humidity such as coals and black shales tend to occur within 5° of the paleoequator and eolian dunes and other evidence of aridity occurs within 10° of the paleoequator. Although steep, the latitudinal climate gradient in the interior of the Pangea supercontinent is not that different from the average modern zonal variation in the balance of evaporation to precipitation even though the distribution of continents was radically different and there is no evidence of continental ice sheets in the Late Triassic. We suggest that the common perception of a dry paleoequator in the Triassic is largely an artifact of observational bias because compilations of paleoclimate proxies usually have spatio-temporal resolutions that are inadequate to delineate narrow zonal climate belts, giving an aliased impression of ancient climate.
Geomagnetic reversal frequency since the Late Cretaceous

description: Models of geomagnetic reversals as a stochastic or gamma renewal process have generally been tested for the Heirtzler et al. [1] magnetic polarity time scale which has subsequently been superseded. Examination of newer time scales shows that the mean reversal frequency is dominated in the Cenozoic and Late Cretaceous by a linearly increasing trend on which a rhythmic fluctuation is superposed. Subdivision into two periods of stationary behavior is no longer warranted. The distribution of polarity intervals is visibly not Poissonian but lacks short intervals. The LaBrecque et al. [2] polarity time scale shows the positions of 57 small-wavelength marine magnetic anomalies which may represent short polarity chrons. After adding these short events the distribution of all polarity intervals in the age range 0-40 Myr is stationary and does not differ significantly from a Poisson distribution. A strong asymmetry develops in which normal polarity chrons are Poisson distributed but reversed polarity chrons are gamma distributed with index k = 2. This asymmetry is of opposite sense to previous suggestions and results from the unequal distribution of the short polarity chrons which are predominantly of positive polarity and concentrated in the Late Cenozoic. If short-wavelength anomalies arise from polarity chrons, the geomagnetic field may be more stable in one polarity than the other. Alternative explanations of the origin of short-wavelength marine magnetic anomalies cast doubt on the inclusion of them as polarity chrons, however. The observed behavior of reversal frequency suggests that core processes governing geomagnetic reversals possess a long-term memory.

description: The problem of variation of spectral subspaces for linear self-adjoint operators under an additive bounded perturbation is considered. The aim is to find the best possible upper bound on the norm of the difference of two spectral projections associated with isolated parts of the spectrum of the perturbed and unperturbed operators. In the approach presented here, a constrained optimization problem on a specific set of parameters is formulated, whose solution yields an estimate on the arcsine of the norm of the difference of the corresponding spectral projections. The problem is solved explicitly. This optimizes the approach by Albeverio and Motovilov in [Complex Anal. Oper. Theory 7 (2013), 1389--1416]. In particular, the resulting estimate is stronger than the one obtained there.

description: In a sequential auction with multiple bidding agents, it is highly challenging to determine the ordering of the items to sell in order to maximize the revenue due to the fact that the autonomy and private information of the agents heavily influence the outcome of the auction. The main contribution of this paper is two-fold. First, we demonstrate how to apply machine learning techniques to solve the optimal ordering problem in sequential auctions. We learn regression models from historical auctions, which are subsequently used to predict the expected value of orderings for new auctions. Given the learned models, we propose two types of optimization methods: a black-box best-first search approach, and a novel white-box approach that maps learned models to integer linear programs (ILP) which can then be solved by any ILP-solver. Although the studied auction design problem is hard, our proposed optimization methods obtain good orderings with high revenues. Our second main contribution is the insight that the internal structure of regression models can be efficiently evaluated inside an ILP solver for optimization purposes. To this end, we provide efficient encodings of regression trees and linear regression models as ILP constraints. This new way of using learned models for optimization is promising. As the experimental results show, it significantly outperforms the black-box best-first search in nearly all settings.

description: In recent years there have been reappraisals of a variety of significant stratigraphic sections across the Spathian/Anisian (Early/Middle Triassic) boundary (Wang, 1985; Bucher, 1989; Tozer and Talon, 1990; Gradinaru, 1991; Gaetani et al., 1992). At present, sections in Oman, Dobrudgea (Romania) and Chios (Greece) appear to be the most relevant sections described in pelagic Tethyan environments. All of them are comprised of pinkish to reddish nodular limestones with low sedimentation rates. The Himalayan sections do not seem to be suitable, essentially because the boundary occurs within the so-called Niti Limestone (Nicora et al., 1984), where ammonoids are badly preserved and almost impossible to chisel out. As regards magnetostratigraphy it is worth noting that, although a paleomagnetic survey has not been attempted, the Color Alteration Index of conodonts (4 to 5) suggests that the region underwent high regional heating (more than 300 °C?) that may have reset the magnetization. In SE China (Yangtze Platform) the critical interval is condensed and is characterized by mixed ammonoid faunas (Wang, 1985), whereas in Nevada the critical interval around the boundary falls within the poorly fossiliferous "Brown Sandstones" (Silberling and Wallace, 1969). As Bucher (1989) reports, the first ammonoid-bearing level above this terrigenous unit is the J. welteri horizon. Thus, the most suitable sections for the Global Stratotype Section and Point (GSSP) of the base of the Anisian seem to be, at present, the western Tethyan Oman, Dobrudgea and Chios sections.

description: The article "Chronology of fluctuating sea levels since the Triassic" ( 1) provides a new version of the Exxon-based sea level and sedimentary cycles chart, calibrated to a new geological time scale. It is not clear to us (i) how and why this time scale differs from other recently published scales (2-5); (ii) what the criteria are that are used to correlate the first-, second-, and third-order sedimentary onlap events; and (iii) where the type sections are for the sedimentary sequences.
LE PROBLEME DE L'HORIZON CHEZ HUSSERL ET MERLEAU-PONTY

description: Cet article qui porte sur le problème de l'horizon, montre comment cet horizon est compris d'une part par Husserl à partir de la conscience transcendantale et d'autre part par Merleau-Ponty au moyen du monde. Si pour Husserl l'horizon se comprend par l'état de conscience, pour Merleau-Ponty cependant l'horizon reste ce lieu du monde invisible par lequel les consciences se perçoivent sans parvenir à épuiser la perception de l'horizon. L'article tourne ainsi autour de l'enjeu de la discussion phénoménologique, qui montre finalement que, si Husserl enferme l'horizon dans la conscience qui le contient, Merleau-Ponty voit dans l'horizon l'inépuisable lieu du monde, qui ouvre mutuellement les consciences l'une sur l'autre.

Promoting and Resisting Student “Success”: Critical Information Literacy Instruction in the Neoliberal Academic Library
Creators: name: Beilin, Ian G.

Subjects: Library science

description: How can a critical library praxis encourage and support students’ academic and career success but still remain faithful to the struggle against the system of inequality and oppression that enables that success? Is student success an affirmation of the neoliberal myth that personal initiative, honest hard work and worthy talent will receive their just rewards? This presentation problematizes the idea of success and explores ways that students can learn important skills and knowledge to advance themselves in a corporatized, privatized world governed by individualistic competition, while also learning how those abilities can be used to challenge and undermine that system.

description: Carbon-rich Wolf-Rayet binaries are a prominent source of carbonaceous dust that contribute to the dust budget of galaxies. The "textbook" example of an episodic dust producing WR binary, WR140 (HD193793), provides us with an ideal laboratory for investigating the dust physics and kinematics in an extreme environment. This study is among the first to utilize two separate JWST observations, from Cycle 1 ERS (July 2022) and Cycle 2 (Sept. 2023), to measure WR140's dust kinematics and confirm its morphology. To measure the proper motions and projected velocities of the dust shells, we performed a novel PSF subtraction to reduce the effects of the bright diffraction spikes and carefully aligned the Cycle 2 to the Cycle 1 images. At 7.7 $μ$m, through the bright feature common to 16 dust shells (C1), we find an average dust shell proper motion of $390\pm29$ mas yr$^{-1}$, which equates to a projected velocity of $2714\pm188$ km s$^{-1}$ at a distance of 1.64 kpc. Our measured speeds are constant across all visible shells and consistent with previously reported dust expansion velocities. Our observations not only prove that these dusty shells are astrophysical (i.e., not associated with any PSF artifact) and originate from WR140, but also confirm the "clumpy" morphology of the dust shells, in which identifiable substructures within certain shells persist for at least 14 months from one cycle to the next. These results support the hypothesis that clumping in the wind collision region is required for dust production in WR binaries.

description: In this paper we studied the behavior of radial photons from the point of view of the coordinate time in (asymptotically) Lifshitz space-times, and we found a generalization to the result reported in previous works by Cruz et. al. [Eur. Phys. J. C {\bf 73}, 7 (2013)], Olivares et. al. [Astrophys. Space Sci. {\bf 347}, 83-89 (2013)], and Olivares et. al. [arXiv: 1306.5285]. We demonstrate that all asymptotically Lifshitz space-times characterized by a lapse funcion $f(r)$ which tends to one when $r\rightarrow \infty$, present the same behavior, in the sense that an external observer will see that photons arrive at spatial infinity in a finite coordinate time. Also, we show that radial photons in the proper system cannot determine the presence of the black hole in the region $r_+

description: Critical Information Literacy does not dispense with teaching ‘rules’ (of grammar, citation, research, writing, etc.), but also places these elements within larger frameworks of critical dialogue, creative thinking and learning, and political and historical inquiry. All of these elements together empower students far more than a mastering of the rules and techniques of research. “Research and Documentation for the Information Age” is the critical information literacy course currently offered by the Library department at New York City College of Technology. With the luxury of three credits, we emphasize integration of library skills into all facets of assignments rather than presenting them as discrete competencies to be mastered and measured. Students come away not only with the ability to succeed in the world, but also with an ability to better understand their world’s origins, structures, and functions, and with a clearer idea of how those structures are contingent and open to challenge. In other words, critical information literacy enables students to believe that they have the ability to change that world.
