description: We use Pantheon Type Ia supernova (SN Ia) apparent magnitude, DES-3yr binned SN Ia apparent magnitude, Hubble parameter, and baryon acoustic oscillation measurements to constrain six spatially flat and non-flat cosmological models. These sets of data provide mutually consistent cosmological constraints in the six cosmological models we study. A joint analysis of these data sets provides model-independent estimates of the Hubble constant, $H_0=68.8\pm1.8\ \rm{km \ s^{-1} \ Mpc^{-1}}$, and the non-relativistic matter density parameter, $Ω_{\rm m_0}=0.294\pm0.020$. Although the joint constraints prefer mild dark energy dynamics and a little spatial curvature, they do not rule out dark energy being a cosmological constant and flat spatial hypersurfaces. We also add quasar angular size and H II starburst galaxy measurements to the combined data set and find more restrictive constraints.

description: In this work we study the diamagnetic properties of a perfect quantum gas in the presence of a constant magnetic field of intensity $B$. We investigate the Gibbs semigroup associated to the one particle operator at finite volume, and study its Taylor series with respect to the field parameter $ω:= eB/c$ in different topologies. This allows us to prove the existence of the thermodynamic limit for the pressure and for all its derivatives with respect to $ω$ (the so-called generalized susceptibilities).

description: The present political regime in Nigeria under the All Progressive Congress (APC) led government by General Mohammed Buhari (Retd) has been waging a yeoman war against corruption. The dictionary meaning of Corruption being illegal or dishonest behavior. Buhari having won the election to run for another term of four years has sworn to continue with the battle. Unfortunately, in Nigeria, corruption has become an enormous timber that has branches. Some of these evil branches are dishonesty, immoral behaviors, bribery and all forms of illegalities that you can think of. Corruption has eaten deep into the fabrics of the nation.

description: Magnetic skyrmions have attracted considerable interest, especially after their recent experimental demonstration at room temperature in multilayers. The robustness, nanoscale size and non-volatility of skyrmions have triggered a substantial amount of research on skyrmion-based low-power, ultra-dense nanocomputing and neuromorphic systems such as artificial synapses. Room-temperature operation is required to integrate skyrmionic synapses in practical future devices. Here, we numerically propose a nanoscale skyrmionic synapse composed of magnetic multilayers that enables room-temperature device operation tailored for optimal synaptic resolution. We demonstrate that when embedding such multilayer skyrmionic synapses in a simple spiking neural network (SNN) with unsupervised learning via the spike-timing-dependent plasticity rule, we can achieve only a 78% classification accuracy in the MNIST handwritten data set under realistic conditions. We propose that this performance can be significantly improved to about 98.61% by using a deep SNN with supervised learning. Our results illustrate that the proposed skyrmionic synapse can be a potential candidate for future energy-efficient neuromorphic edge computing.

description: Through photoionization modeling, constraints on the physical conditions of three z ~ 1.7 single-cloud weak Mg II systems (W_r(2796) < 0.3A) are derived. Constraints are provided by high resolution R = 45,000, high signal-to-noise spectra of the three quasars HE0141-3932, HE0429-4091, and HE2243-6031 which we have obtained from the ESO archive of VLT/UVES. Results are as follows: (1) The single-cloud weak Mg II absorption in the three z ~ 1.7 systems is produced by clouds with ionization parameters of -3.8 < logU < -2.0 and sizes of 1-100 pc. (2) In addition to the low-ionization phase Mg II clouds, all systems need an additional 1-3 high-ionization phase C IV clouds within 100 km/s of the Mg II component. The ionization parameters of the C IV phases range from -1.9 < logU < -1.0, with sizes of tens of parsecs to kiloparsecs. (3) Two of the three single-cloud weak Mg II absorbers have near-solar or super-solar metallicities, if we assume a solar abundance pattern. Although such large metallicities have been found for z < 1 weak Mg II absorbers, these are the first high metallicities derived for such systems at higher redshifts. (4) Two of the three weak Mg II systems also need additional low-metallicity, broad Lya absorption lines, offset in velocity from the metal-line absorption, in order to reproduce the full Lya profile. (5) Metallicity in single-cloud weak Mg II systems are more than an order of magnitude larger than those in Damped Lya systems at z ~ 1.7. In fact, there appears to be a gradual decrease in metallicity with increasing N(HI), from these, the most metal-rich Lya forest clouds, to Lyman limit systems, to sub-DLAs, and finally to the DLAs.

description: This study investigated the influence of non- monetary Rewards System on Library Staff Performance in polytechnics in Nigeria. A survey research design was adopted and a questionnaire was used for data collection. Purposive sampling technique was used in selecting the sample for the study. The total population is fifty- eight (58) library staff in polytechnics library in Edo state. The copies of the questionnaire retrieved and analyzed using mean score, standard deviation, frequency counts and percentage. From the analysis of data collected, the findings revealed that verbal recognition/praise, awards, office gettogether/end of year celebration and special treats are the major forms of recognition used by Auchi polytechnic library management to influence staff performance. Flexible work schedule, increase freedom, participation in decision making and decentralizing authority are the major forms of non- monetary rewards employed by the library management to influence library staff performance. However, improve performance /services, confidence, job satisfaction, increase productivity, commitment/dedication, feelings of accomplishment and loyalty are the major influence of independence and recognition rewards on library staff. The study recommended that Polytechnics library management should improve and sustain the culture of celebrating staff achievement and performance. Rewards must be provided equitably based on performance.
Post-Einsteinian tests of linearized gravitation

description: The general relativistic treatment of gravitation can be extended by preserving the geometrical nature of the theory but modifying the form of the coupling between curvature and stress tensors. The gravitation constant is thus replaced by two running coupling constants which depend on scale and differ in the sectors of traceless and traced tensors. When calculated in the solar system in a linearized approximation, the metric is described by two gravitation potentials. This extends the parametrized post-Newtonian (PPN) phenomenological framework while allowing one to preserve compatibility with gravity tests performed in the solar system. Consequences of this extension are drawn here for phenomena correctly treated in the linear approximation. We obtain a Pioneer-like anomaly for probes with an eccentric motion as well as a range dependence of Eddington parameter $γ$ to be seen in light deflection experiments.

description: As host to two accreting planets, PDS 70 provides a unique opportunity to probe the chemical complexity of atmosphere-forming material. We present ALMA Band 6 observations of the PDS~70 disk and report the first chemical inventory of the system. With a spatial resolution of 0.4''-0.5'' ($\sim$50 au), 12 species are detected, including CO isotopologues and formaldehyde, small hydrocarbons, HCN and HCO+ isotopologues, and S-bearing molecules. SO and CH3OH are not detected. All lines show a large cavity at the center of the disk, indicative of the deep gap carved by the massive planets. The radial profiles of the line emission are compared to the (sub-)mm continuum and infrared scattered light intensity profiles. Different molecular transitions peak at different radii, revealing the complex interplay between density, temperature and chemistry in setting molecular abundances. Column densities and optical depth profiles are derived for all detected molecules, and upper limits obtained for the non detections. Excitation temperature is obtained for H2CO. Deuteration and nitrogen fractionation profiles from the hydro-cyanide lines show radially increasing fractionation levels. Comparison of the disk chemical inventory to grids of chemical models from the literature strongly suggests a disk molecular layer hosting a carbon to oxygen ratio C/O>1, thus providing for the first time compelling evidence of planets actively accreting high C/O ratio gas at present time.

The reports – signed by Domenico Campanari and addressed to Karl Josias von Bunsen – span the entire second excavation season between November 9th 1835 and May 28th 1836 both on the plateau of the Etrusco-Roman city and in the necropolis. We have been able to identify a group of 37 objects in various European and non-European museums and collections and connect them with the excavations of the Campanaris in Vulci. It was thus possible outline the lively network of antiquarians, scholars and collectors within which the Campanaris operated and for whom scientific and commercial interests appeared complementary.
Characterization of classical pathway complement activation by liposomes and modulation by incorporated poly (ethylene glycol)
Creators: name: Bradley, Amanda Joan
Publisher: name: University of British Columbia
Year: 2009

description: Complement activation causes opsonization of foreign particles leading to particle elimination from the blood. Complement-mediated opsonization of charged and large liposomes presents a fundamental problem in their use to deliver therapeutic agents in vivo. To prolong the circulation half-lives of such liposomes, complement activation must be curtailed. The two overall aims of this study were to characterize complement activation through antibody-independent C1q binding to anionic liposomes and to assess the ability of poly(ethylene glycol)-lipids (PEG-lipids) to inhibit this complement activation. This study determined that both electrostatic and chemical forces contributed to C1q binding to anionic liposomes. Negative phospholipids in the liposome composition were required to detect C1 q binding to liposomes. At close to physiologic pH (7.2) and ionic strength (0.145 M) and in the absence or presence of serum, anionic liposomes bound a measurable but small amount of C1q . However, as the concentration of negative phospholipid in the liposomes increased, C1q binding increased. C1q binding increased even more as the ionic strength or the pH decreased. C1q peptide studies also demonstrated the importance of electrostatics. Peptides composed of residues 14-26 of the C1qA chain (C1qA₁₄[sub -]₂₆ ) bearing a net charge of plus five inhibited C1q binding and complement activation by anionic liposomes. This inhibitory capacity was dependent on the peptide's five positive charges and was independent of conformation or amino acidsequence. While electrostatics were important in determining C1q saturation binding, C1q binding affinity constants were independent of the electrostatic component suggesting that chemical forces were also involved. Clq-mediated complement activation was also affected by liposome size. For cardiolipin-containing liposomes, 240 nm vesicles bound more C1q and activated complement more readily than 100 nm vesicles. Multilamellar vesicles (∽1-8 μm) bound 15 times more C1q than 240 nm liposomes. This study is the first to show the ability of PEG-lipids to act as a barrier against complement activation by anionic liposomes. Incorporation of either cholesterol-PEG₆₀₀ (CH-PEG₆₀₀) , cholesterol-PEG₁₀₀₀ (CH-PEG₁₀₀₀) , or phosphatidylethanolamine-PEG₂₀₀₀ (PE-PEG₂₀₀₀) caused PEG-lipid dose-dependent inhibition of C1q binding to and complement activation by large anionic liposomes. Complement activation was strongly inhibited when 15 mole % of CH-PEG₆₀₀, 10 mole % CH - PEG₁₀₀₀, or 5 mole % PE - PEG₂₀₀₀ were incorporated into 100 nm anionic liposomes.

description: Long-range exchange and correlation effects, responsible for the failure of currently used approximate density functionals in describing van der Waals forces, are taken into account explicitly after a separation of the electron-electron interaction in the Hamiltonian into short- and long-range components. We propose a "range-separated hybrid" functional based on a local density approximation for the short-range exchange-correlation energy, combined with a long-range exact exchange energy. Long-range correlation effects are added by a second-order perturbational treatment. The resulting scheme is general and is particularly well-adapted to describe van der Waals complexes, like rare gas dimers.

description: Topological phases, including the conventional first-order and higher-order topological insulators and semimetals, have emerged as a thriving topic in the fields of condensed-matter physics and material science. Usually, a topological insulator is characterized by a fixed order topological invariant and exhibits associated bulk-boundary correspondence. Here, we realize a new type of topological insulator in a bilayer phononic crystal, which hosts simultaneously the first-order and second-order topologies, referred here as the hybrid-order topological insulator. The one-dimensional gapless helical edge states, and zero-dimensional corner states coexist in the same system. The new hybrid-order topological phase may produce novel applications in topological acoustic devices.

description: Recently there was a significant change of views on physical properties and underlying dynamics of Quark-Gluon Plasma at $T=170-350 MeV$, produced in heavy ion collisions at RHIC. Instead of being a gas of $q,g$ quasiparticles, a near-perfect liquid is observed. Also, precisely in this temperature interval, the interaction deduced from lattice studies is strong enough to support multiple binary bound states. This work is the first variational study of {\em multibody} bound states. We will consider: (i) ``polymer chains'' of the type $\bar q g g ..g q$; (ii) baryons $(qqq)$; (iii) closed (3-)chains of gluons $(ggg)$. We found that chains (i) form in exactly the same $T$ range as binary states, with the same binding {\em per bond}. The binding and $T$-range for diquarks, baryons and closed 3-chains are also established. We point out that the presence of chains, or possibly even a chain network, may drastically change the transport properties of matter, such as charm diffusion or jet energy loss. We further suggest that it seems to exist only for $T=(1-1.5)T_c$ and thus there may be a ``latent period'' for charm/jet quenching in RHIC collisions, while matter cools down to such $T$.

description: The Neil Gehrels Swift Observatory followed up 18 gravitational wave (GW) triggers from the LIGO/Virgo collaboration during the O3 observing run in 2019/2020, performing approximately 6500 pointings in total. Of these events, four were finally classified (if real) as binary black hole (BH) triggers, six as binary neutron star (NS) events, two each of NSBH and Mass Gap triggers, one an unmodelled (Burst) trigger, and the remaining three were subsequently retracted. Thus far, four of these O3 triggers have been formally confirmed as real gravitational wave events. While no likely electromagnetic counterparts to any of these GW events have been identified in the X-ray data (to an average upper limit of 3.60 x 10^{-12} erg cm^{-2} s^{-1} over 0.3-10 keV), or at other wavelengths, we present a summary of all the Swift-XRT observations performed during O3, together with typical upper limits for each trigger observed. The majority of X-ray sources detected during O3 were previously uncatalogued; while some of these will be new (transient) sources, others are simply too faint to have been detected by earlier survey missions such as ROSAT. The all-sky survey currently being performed by eROSITA will be a very useful comparison for future observing runs, reducing the number of apparent candidate X-ray counterparts by up to 95 per cent.

title: Negotiating with social algorithms in the design of service personalization
Creators: name: Dodd, Cody
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2021

description: Supported by three standalone yet complimentary essays, this thesis investigates the development of service personalization that has been mediated by technologies characterized as having elements of Artificial Intelligence (AI), including prediction, natural language processing, and machine learning. The aim of this work is to expand our understanding of the role emerging technologies play in affording personalization, and personalization’s relationship with systems increasingly capable of mediating experiences directly with users. Data was collected from participant observation of an AI development company over two and a half years and comprised of a detailed mapping of the technologies as well as development documents, chats, meetings, and interviews with developers and key users. We found that the implementation of deeper forms of personalization over time led to the adoption of emerging technologies like AI. In the context of a government agency, these algorithms changed the way employees are screened and selected. We also found that requests for personalization led to increasingly opaque systems where interpretation about how algorithms work emerges in place of an explanation of how they work. Building upon these findings, a framework was developed to investigate 34 discrete cases of personalization across dimensions of ease of design and ease of understanding. We found that the pursuit of deeper personalization leads to the adoption of tools that make increasingly social decisions. That is, we utilize social technologies despite their complexity because they make faster and deeper decisions about individuals from social data than can be done without them. To accomplish this, various strategies are employed to help increase user tolerance for a lack of understanding of their inner workings and to ensure they operate within bounds acceptable to users and the designers of the systems. As these systems gain increasing autonomy, issues of bias amplification, privacy, and an increasingly inexplainable logic behind decision-making remain persistent and this has implications for theory and practice.

description: In this paper we present a new, accurate determination of the three components of the absolute space velocity of the Galactic globular cluster NGC6397 (l 338d, b -12d). We used three HST/WFPC2 fields with multi-epoch observations to obtain astrometric measurements of objects in three different fields in this cluster. The identification of 33 background galaxies with sharp nuclei allowed us to determine an absolute reference point and measure the absolute proper motion of the cluster. The third component has been obtained from radial velocities measured on spectra from the multi-fiber spectrograph FLAMES at UT2-VLT. We find [mu_alpha cos(delta), mu_delta](J2000.0) = [+3.39 +/- 0.15, -17.55 +/- 0.15] mas/yr, and V_rad = +18.36 +/- 0.09 (+/-0.10) km/s. Assuming a Galactic potential, we calculate the cluster orbit for various assumed distances, and briefly discuss the implications.

We show that the field dressing becomes important at long laser wavelengths ($\approx 2 μ$m), leading to an overall reduction of harmonic generation and modifying the ratio of harmonic signals from different isotopes.

description: The opacity of spiral galaxy disks, from counts of distant galaxies, is compared to HI column densities. The opacity measurements are calibrated using the ``Synthetic Field Method'' from Gonzalez et al (1998) and Holwerda et al. (2005a). When compared for individual disks, the HI column density and dust opacity do not seem to be correlated as HI and opacity follow different radial profiles. To improve statistics, an average radial opacity profile is compared to an average HI profile. Compared to dust-to-HI estimates from the literature, more extinction is found in this profile. This difference may be accounted for by an underestimate of the dust in earlier measurements due to their dependence on dust temperature. Since the SFM is insensitive to the dust temperature, the ratio between the SFM opacity and HI could very well be indicative of the true ratio. Earlier claims for a radially extended cold dust disk were based on sub-mm observations. A comparison between sub-mm observations and counts of distant galaxies is therefore desirable. We present the best current example of such a comparison, M51, for which the measurements seem to agree. However, this remains an area where improved counts of distant galaxies, sub-mm observations and our understanding of dust emissivity are needed.

description: Field research at Babunjë, a small fortified settlement of ca. 5 ha lying between the Corinthian-Corcyraian colonies of Apollonia and Epidamnos, seeks to achieve a better understanding of the colonial settlement structure at the eastern coast of the southern Adriatic (and further south along the Ionian Sea). Babunjë was founded at the end of the 6th century BC and was abandoned in the last decades of the 4th century BC. The site had a fortification with a ‚bastion‘ or unusual large tower which was built some decades after Babunjë’s foundation. A planned urban layout shows long, narrow insulae with single rows of house-plots. A two-roomed house was excavated completely. Small settlements like Babunjë were, after the large colonies, most probably an important part of the colonial settlement structure on this coast.

description: We study the formation of H2 in the ISM, using a modified version of the astrophysical magnetohydrodynamical code ZEUS-MP that includes a non-equilibrium treatment of the formation and destruction of H2. We examine two different approximations to treat the shielding of H2 against photodissociation: a local approximation, which gives us a solid lower bound on the amount of shielding, and a method based on ray-tracing that is considerably more accurate in some circumstances but that produces results that are harder to clearly interpret. Either approximation allows one to perform three-dimensional high-resolution simulations of cloud formation with only modest computational resources. We also include a detailed treatment of the thermal behaviour of the gas. In this paper, we focus on the problem of molecular cloud formation in gravitationally unstable, initially static gas. We show that in these conditions, and for initial densities consistent with those observed in the cold, neutral atomic phase of the interstellar medium, H2 formation occurs on a timescale t > 10 Myr, comparable to or longer than the gravitational free-fall timescale of the cloud. We also show that the collapsing gas very quickly reaches thermal equilibrium and that the equation of state of the gas is generally softer than isothermal. Finally, we demonstrate that although these results show little sensitivity to variations in most of our simulation parameters, they are highly sensitive to the assumed initial density n_i. Reducing n_i significantly increases the cloud formation timescale and decreases the amount of hydrogen ultimately converted to H2. (Abridged).

description: We consider a recently introduced geometrically nonlinear elastic Cosserat shell model incorporating effects up to order $O(h^5)$ in the shell thickness $h$. We develop the corresponding geometrically nonlinear constrained Cosserat shell model, we show the existence of minimizers for the $O(h^5)$ and $O(h^3)$ case and we draw some connections to existing models and classical shell strain measures. Notably, the role of the appearing new bending tensor is highlighted and investigated with respect to an invariance condition of Acharya [Int. J. Solids and Struct., 2000] which will be further strengthened.

description: In this paper we give a new proof of the (strong) displacement convexity of a class of integral functionals defined on a compact Riemannian manifold satisfying a lower Ricci curvature bound. Our approach does not rely on existence and regularity results for optimal transport maps on Riemannian manifolds, but it is based on the Eulerian point of view recently introduced by Otto-Westdickenberg and on the metric characterization of the gradient flows generated by the functionals in the Wasserstein space.

Level set simulations of turbulent thermonuclear deflagration in degenerate carbon and oxygen

description: We study the dynamics of thermonuclear flames propagating in fuel stirred by stochastic forcing. The fuel consists of carbon and oxygen in a state which is encountered in white dwarfs close to the Chandrasekhar limit. The level set method is applied to represent the flame fronts numerically. The computational domain for the numerical simulations is cubic, and periodic boundary conditions are imposed. The goal is the development of a suitable flame speed model for the small-scale dynamics of turbulent deflagration in thermonuclear supernovae. Because the burning process in a supernova explosion is transient and spatially inhomogeneous, the localised determination of subgrid scale closure parameters is essential. We formulate a semi-localised model based on the dynamical equation for the subgrid scale turbulence energy $k_{\mathrm{sgs}}$. The turbulent flame speed $s_{\mathrm{t}}$ is of the order $\sqrt{2k_{\mathrm{sgs}}}$. In particular, the subgrid scale model features a dynamic procedure for the calculation of the turbulent energy transfer from resolved toward subgrid scales, which has been successfully applied to combustion problems in engineering. The options of either including or suppressing inverse energy transfer in the turbulence production term are compared. In combination with the piece-wise parabolic method for the hydrodynamics, our results favour the latter option. Moreover, different choices for the constant of proportionality in the asymptotic flame speed relation, $s_{\mathrm{t}}\propto\sqrt{2k_{\mathrm{sgs}}}$, are investigated.

description: Two-dimensional (2D) semiconductors are promising channel materials for next-generation field-effect transistors (FETs) thanks to their unique mechanical properties and enhanced electrostatic control. However, the performance of these devices can be strongly limited by the scattering processes between carriers and phonons, usually occurring at high rates in 2D materials. Here, we use quantum transport simulations calibrated on first-principle computations to report on dissipative transport in antimonene and arsenene $n$-type FETs at the scaling limit. We show that the widely-used approximations of either ballistic transport or simple acoustic deformation potential scattering result in large overestimation of the ON current, due to neglecting the dominant intervalley and optical phonon scattering processes. We additionally investigate valley engineering strategy [Nano Lett. \textbf{19}, 3723 (2019)] to improve the device performance by removing the valley degeneracy and suppressing most of the intervalley scattering channels via an uniaxial strain along the zigzag direction. The method is applicable to other similar 2D semiconductors characterized by multivalley transport.
