description: This paper develops a new route choice modelling framework that deals with both route correlations and unrealistic routes in a consistent and robust way. To do this, we explore the integration of a correlation-based Path Size Logit model with the Bounded Choice Model (BCM) (Watling et al. 2018. “Stochastic User Equilibrium with a Bounded Choice Model.” Transportation Research Part B: Methodological 114: 254–280). We find, however, that the natural integration of these models leads to behavioural inconsistencies and/or undesirable mathematical properties. Solving these challenges, we derive a mathematically well-defined Bounded Path Size (BPS) model form that utilises a consistent criterion for assigning zero choice probabilities to unrealistic routes while eliminating their path size contributions. A closed-form and fixed-point BPS model are consequently formulated. Subsequently, we consider parameter estimation in a simulation study and on a real-life large-scale network using GPS data, where computational feasibility is demonstrated. Estimation results show the potential of the BPS models to give improved fit relative to non-bounded versions (and BCM).

description: We investigate the effect of the Continuous Spontaneous Localization (CSL) model on light-pulse atom interferometry. Using a path-integral approach with an additional stochastic potential accounting for CSL, we derive an exponential loss of the contrast that scales linearly with the interferometer time $T$ if both interferometer arms are spatially separated. We compare our theoretical results with measurements from a cold rubidium atom interferometer based on counter-propagating two-photon transitions with pulse separation times up to $T$ = 260 ms and obtain the corresponding bounds on the CSL parameters.

description: A thought experiment is proposed to demonstrate the existence of a gravitational, vector Aharonov-Bohm effect. A connection is made between the gravitational, vector Aharonov-Bohm effect and the principle of local gauge invariance for nonrelativistic quantum matter interacting with weak gravitational fields. The compensating vector fields that are necessitated by this local gauge principle are shown to be incorporated by the DeWitt minimal coupling rule. The nonrelativistic Hamiltonian for weak, time-independent fields interacting with quantum matter is then extended to time-dependent fields, and applied to problem of the interaction of radiation with macroscopically coherent quantum systems, including the problem of gravitational radiation interacting with superconductors. But first we examine the interaction of EM radiation with superconductors in a parametric oscillator consisting of a superconducting wire placed at the center of a high Q superconducting cavity driven by pump microwaves. We find that the threshold for parametric oscillation for EM microwave generation is much lower for the separated configuration than the unseparated one, which then leads to an observable dynamical Casimir effect. We speculate that a separated parametric oscillator for generating coherent GR microwaves could also be built.

description: A critical early stage for the origin of life on Earth may have involved the production of hydrogen cyanide (HCN) in a reducing, predominantly H$_2$ atmosphere. HCN is crucial for the origin of life as it is a possible precursor to several biomolecules that make up RNA and proteins including nucleobases, nucleotides, amino acids, and ribose. In this work, we perform an in depth experimental and theoretical investigation of HCN production in reducing atmospheric conditions (89-95% H$_2$) possibly representing the earliest stages of the Hadean eon, ~4.5-4.3 billion years ago. We make use of cold plasma discharges - a laboratory analog to shortwave UV radiation - to simulate HCN production in the upper layers of the atmosphere for CH$_4$ abundances ranging from 0.1-6.5%. We then combine experimental mass spectrum measurements with our theoretical plasma models to estimate the HCN concentrations produced in our experiments. We find that upper atmospheric HCN production scales linearly with CH$_4$ abundance with the relation [HCN] = 0.13 $\pm$ 0.01[CH$_4$]. Concentrations of HCN near the surface of the Hadean Earth are expected to be about 2-3 orders of magnitude lower. The addition of 1% water to our experiments results in a ~50% reduction in HCN production. We find that four reactions are primarily responsible for HCN production in our experiments: (i) $^4$N + CH$_3$ -> H$_2$CN + H -> HCN + H$_2$, (ii) $^4$N + CH -> CN + H followed by CN + CH$_4$ -> HCN + CH$_3$, (iii) C$_2$H$_4$ + $^4$N -> HCN + CH$_3$, and (iv) $^4$N + $^3$CH$_2$ -> HCN + H. The most prebiotically favorable Hadean atmosphere would have been very rich in CH$_4$ (> 5%), and as a result of greenhouse effects the surface would be likely very hot. In such a prebiotic scenario, it may have been important to incorporate HCN into organic hazes that could later release biomolecules and precursors into the first ponds.

Constraining the SN Ia Host Galaxy Dust Law Distribution and Mass Step: Hierarchical BayeSN Analysis of Optical and Near-Infrared Light Curves

description: We use the BayeSN hierarchical probabilistic SED model to analyse the optical-NIR ($BVriYJH$) light curves of 86 Type Ia supernovae (SNe Ia) from the Carnegie Supernova Project to investigate the SN Ia host galaxy dust law distribution and correlations between SN Ia Hubble residuals and host mass. Our Bayesian analysis simultaneously constrains the mass step and dust $R_V$ population distribution by leveraging optical-NIR colour information. We demonstrate how a simplistic analysis where individual $R_V$ values are first estimated for each SN separately, and then the sample variance of these point estimates is computed, overestimates the $R_V$ population variance $σ_R^2$. This bias is exacerbated when neglecting residual intrinsic colour variation beyond that due to light curve shape. Instead, Bayesian shrinkage estimates of $σ_R$ are more accurate, with fully hierarchical analysis of the light curves being ideal. For the 75 SNe with low-to-moderate reddening (peak apparent $B-V\leq0.3$), we estimate an $R_V$ distribution with population mean $μ_R=2.59\pm0.14$, and standard deviation $σ_R=0.62\pm0.16$. Splitting this subsample at the median host galaxy mass ($10^{10.57}~\mathrm{M}_\odot$) yields consistent estimated $R_V$ distributions between low- and high-mass galaxies, with $μ_R=2.79\pm0.18$, $σ_R=0.42\pm0.24$, and $μ_R=2.35\pm0.27$, $σ_R=0.74\pm0.36$, respectively. When estimating distances from the full optical-NIR light curves while marginalising over various forms of the dust $R_V$ distribution, a mass step of $\gtrsim0.06$ mag persists in the Hubble residuals at the median host mass.

description: This study aims to investigate the membrane-stabilizing and clot-lysis activities of an aqueous extract derived from the flowers of Canna indica (CIFA) on human blood in vitro. In this experiment, erythrocyte lysis was induced by a hypotonic solution, and clot formation was created by incubating the blood sample at 37 °C for 45 minutes. We conducted experiments using varying amounts of acetyl salicylic acid 6.25–100 µL and a fixed amount of streptokinase 100 µL as the positive control groups. The group designated as the negative control treated the vehicle. CIFA was treated at doses ranging from 6.25 to 100 µL. CIFA demonstrated dose-dependent membrane stabilizing and clot lysis abilities. The CIFA exhibited a wide range of membrane stabilizing capabilities, with a percentage of 71.03 ± 0.02 at a concentration of 100 µL. The EC50 of the test extract was calculated to be 47.43 ± 1.02 µL. In contrast, CIFA demonstrated clot lysis capabilities of 60.38 ± 2.37% at the same concentration, with the EC50 of the test extract calculated at 91.42 ± 1.86 µL. CIFA demonstrated significant membrane stabilizing and clot lysis activity in human blood, suggesting that they could be promising candidates for the treatment of atherothrombosis.

The first counterexample occurs in type A_5 for p = 2 and involves the same singularity used by Kashiwara and Saito to show the reducibility of the characteristic variety of an intersection cohomology D-module on a quiver variety. Using recent results of Polo one can give counterexamples in type A in all characteristics.

description: Dynamical fluctuations of the globally conserved quantities in heavy ion collision such as baryon number, strangeness, charge, and isospin are suggested to carry information about the deconfinement and chiral phase transitions. The STAR experiment has performed a comprehensive study of the collision energy and charge dependence of dynamical particle ratio ($K/π$, $p/π$, and $K/p$) fluctuations, net-charge fluctuations, and transverse momentum correlations at mid-rapidity, as well as neutral-charge pion fluctuations at forward rapidity. The centrality, charge, and collision energy dependence from new measurements of the fluctuation observables $ν_{dyn}$ and $r_{m,1}$ and the energy dependence of transverse momentum correlations from $\sqrt{s_{NN}}$ = 7.7-200 GeV Au+Au collisions are presented. These results are also compared to predictions from hadronic models.

Για τον σκοπό αυτό, χρησιμοποιήθηκε ο ήδη υπάρχοντας στην βιβλιογραφία αλγόριθμος ‘TWODD’ (Crouch and Starfield, 1990) ο οποίος λύνει προβλήματα στις δύο διαστάσεις.Με βάση αυτόν κατασκευάστηκαν:
•	Κώδικας στο υπολογιστικό πακέτο MATLAB
•	Τροποποιημένος κώδικας για επίλυση στις τρεις διαστάσεις με επίπεδα τριγωνικά στοιχεία (Kuriyama and Mizuta, 1993)

description: This paper is devoted to the classification of integrable Davey-Stewartson type equations. A list of potentially deformable dispersionless systems is obtained through the requirement that such systems must be generated by a polynomial dispersionless Lax pair. A perturbative approach based on the method of hydrodynamic reductions is employed to recover the integrable systems along with their Lax pairs. Some of the found systems seem to be new.

description: We discuss efficient solutions to systems of shifted linear systems arising in computations for oscillatory hydraulic tomography (OHT). The reconstruction of hydrogeological parameters such as hydraulic conductivity and specific storage using limited discrete measurements of pressure (head) obtained from sequential oscillatory pumping tests, leads to a nonlinear inverse problem. We tackle this using the quasi-linear geostatistical approach \cite{kitanidis1995quasi}. This method requires repeated solution of the forward (and adjoint) problem for multiple frequencies, for which we use flexible preconditioned Krylov subspace solvers specifically designed for shifted systems based on ideas in \cite{gu2007flexible}. The solvers allow the preconditioner to change at each iteration. We analyze the convergence of the solver and perform an error analysis when an iterative solver is used for inverting the preconditioner matrices. Finally, we apply our algorithm to a challenging application taken from oscillatory hydraulic tomography to demonstrate the computational gains by using the resulting method.

Africa 7(2), fasc. 2: 68 (1983). — Type: Schlechter 10964, South Africa, Northern Cape, Bokkeveld Mts., Oorlogskloof (lecto-, G, designated by M. P. DE VOS, 1972; isolecto-, B, BM, BOL!, GRA, K!, P, PRE!, S, Z). Plants 12-40 cm high, stem subterranean; corm rounded at base with curved acuminate teeth. Leaves 3-5, basal, filiform, 4-grooved, c. 1 mm diam.; outer bracts usually keeled above, with narrow, usually brown membranous margins, inner bracts 2-keeled usually with brown membranous margins. Flowers dark red, rarely pink, with black blotches at the edge of a creamy green cup, unscented, tepals obovate-cuneate, 25-40 mm long; filaments 3-5 mm long, anthers 8-12 mm long. Fruiting peduncles suberect. Flowering: July-Sep. — Fig. 2D. Romulea sabulosa is a local endemic that grows in large populations in renosterveld on clay and sandy soils on the Bokkeveld Escarpment west of Nieuwoudtville. It is closely related to R. monadelpha, which has similar large red flowers with a pale cup and prominently marked with dark blotches at the base of the tepals. The leaf anatomy of both species is also similar, with a band of subepidermal sclerenchyma along the ribs. The species are best distinguished by details of the filaments. In R. sabulosa the filaments are usually pale greenish and taper from a pubescent base as in most other species of Romulea while in R. monadelpha the black filaments are either united into a short, stout glabrous column or when free are oblong and do not taper toward the apex. Another differences is in the peduncle, which in R. sabulosa is subterete and remains suberect in fruit, but in R. monadelpha is somewhat stouter, with the upper side conspicuously flattened, and is curved in fruit.

description: This work studies whether increased ranges of bistatic scatter radio
communication are possible, especially when low-cost (in the order of 4 Euro),
embedded receivers, originally designed for conventional radio (and not for
scatter radio) are employed. It is found that for 13 dBm emitter
transmission power, 246 meters scatter radio tag-to-reader distance is possible, with packet error rate (PER) less than 1%, while 268 meters are possible at the expense of increased PER, in the order of 10%. A prototype node employing the communication scheme suggested and powered by a supercapacitor along with a solar panel is also built. Additionally an experimental wireless communication link, utilizing the harmonics of a microcontroller’s clock signal as the carrier is presented.

description: Using a beyond-mean-field model including a Lee-Huang-Yang-type interaction, we demonstrate a supersolid-like spatially-periodic square- and triangular-lattice crystallization of droplets in a polarized dipolar condensate confined by an appropriate three-dimensional (3D) box trap. In this paper we consider a rectangular box (cuboid) trap, a square box (cuboid with two equal sides) trap, a cylindrical box trap and a hexagonal box (hexagonal prism) trap. The droplet lattice is always formed in the $x$-$y$ plane perpendicular to the polarization $z$ direction of dipolar atoms. In contrast to a harmonic trap, the box traps allow the formation of a large clean supersolid-like spatially-periodic crystallization in free space without any distortion. Moreover, a droplet lattice can be formed in a 3D box trap with a significantly reduced number of atoms than in a harmonic trap, which could facilitate the experimental observation of droplet lattice in a box trap. With present know-how such a supersolid-like crystallization of dipolar droplets in a 3D box trap can be realized in a laboratory thus allowing the study of a large periodic lattice of dipolar droplets in free space bounded by rigid walls.

description: Having access to realistic and empirically grounded passenger valuations of public transport trip components facilitate the undertaking of necessary trade-offs during planning of transport networks. Discrete choice estimation of path choice preferences is a practical way to obtain such preferences. This paper proposes a new take on the empirical foundation of path choice estimation based on revealed choices by introducing trip data for full activity-based ‘door-to-door’ public transport trips collected from a dedicated survey application for smartphones. Choice probabilities were modelled based on an explicitly generated choice set, where the public transport trip parts were generated using a branch-and-bound approach. Results in terms of estimated preferences are comparable to those based on conventional surveying methods and suggest significant premiums for paths involving public transport stops with an elevated level of passenger service as well as differences in preferences across population groups.

Echinodorus tenellus

description: Echinodorus tenellus (Fig. 3 A-E) En Mph le pollen est homogène, sphérique et mesure 24-26(-35) µm de diamètre; il est périporé, le nombre d’apertures étant de 12-16(-26). En MeB, l’exine est microéchinulée; sur le tectum les épines sont très courtes et élargies à la base. Le tectum est irrégulier en profondeur et les régions amincies donnent l’image d’un « réseau » en profondeur en L.O. analyse (PUNT & REUMER 1981). L’infratectum est formé de columelles régulières, fines, cylindriques ou obconiques (Fig. 3E). La nexine est scabre et microperforée. La membrane aperturale est formée de gemmules ou verrues microéchinulées (Fig. 3C) formant des îlots ectexiniques (moins de 18). En profondeur, les apertures sont mal délimitées (Fig. 3D) et la nexine irrégulière semble continue; il n’y a donc pas de véritable endoaperture. Le pollen des trois échantillons étudiés est comparable à celui déjà décrit par ARGUE (1976) et HESSE (1980).

description: Conventional neuro-computing architectures and artificial neural networks have often been developed with no or loose connections to neuroscience. As a consequence, they have largely ignored key features of biological neural processing systems, such as their extremely low-power consumption features or their ability to carry out robust and efficient computation using massively parallel arrays of limited precision, highly variable, and unreliable components. Recent developments in nano-technologies are making available extremely compact and low-power, but also variable and unreliable solid-state devices that can potentially extend the offerings of availing CMOS technologies. In particular, memristors are regarded as a promising solution for modeling key features of biological synapses due to their nanoscale dimensions, their capacity to store multiple bits of information per element and the low energy required to write distinct states. In this paper, we first review the neuro- and neuromorphic-computing approaches that can best exploit the properties of memristor and-scale devices, and then propose a novel hybrid memristor-CMOS neuromorphic circuit which represents a radical departure from conventional neuro-computing approaches, as it uses memristors to directly emulate the biophysics and temporal dynamics of real synapses. We point out the differences between the use of memristors in conventional neuro-computing architectures and the hybrid memristor-CMOS circuit proposed, and argue how this circuit represents an ideal building block for implementing brain-inspired probabilistic computing paradigms that are robust to variability and fault-tolerant by design.

description: In this diploma thesis, we study the problem of optimal noncoherent trellis decoding, that is, the maximization of |s(x)^H y| over x, where y is a complex vector, x is a discrete symbol sequence, and s(x) is a vector that is produced by x through a trellis structure. Two example cases of noncoherent trellis decoding are noncoherent detection of a minimum-shift keying (MSK) modulated sequence and noncoherent decoding of convolutionally encoded data. Specifically, MSK is a modulation scheme that limits problems associated with nonlinear distortion and is used in a variety of applications, like signal transmission from satellites and broadcasting. Although the optimal coherent MSK receiver simplifies to constant-complexity symbol-bysymbol detection, optimal noncoherent reception of MSK takes the form of sequence detection (due to channel-induced memory) which has exponential (in the sequence length) complexity when implemented through an exhaustive search among all possible sequences. Convolutional codes are used extensively to achieve reliable data transfer in numerous applications, such as digital video, radio, and satellite communications. They are modeled by a trellis structure and optimal noncoherent reception of convolutionally encoded data also takes the form of sequence detection. In this work, we present an algorithm that performs generalized-likelihood-ratio-test (GLRT) optimal noncoherent sequence detection of MSK signals in flat fading with log-linear (in the sequence length) complexity. Moreover, for Rayleigh fading channels, the proposed algorithm is equivalent to the maximum-likelihood (ML) noncoherent sequence detector. We then discuss how the proposed algorithm can be generalized for use on noncoherent convolutional decoding. To simplify the presentation, we consider a particular convolutional code and modify the proposed algorithm to perform optimal noncoherent trellis decoding with empirically low complexity. Simulation studies indicate that the optimal noncoherent MSK detector attains coherent-detection performance when the sequence length is on the order of 100, offering a 5–6 dB gain over the typical single-symbol detector. Similar results are obtained for the generalized algorithm on convolutional decoding.

description: We discuss the dynamics in finite density medium including a heavy impurity particle (hadron or quark) with a heavy flavor, charm and bottom, at zero temperature. As a system, we consider a $\bar{D}$ ($B$) meson embedded in nuclear matter as a heavy impurity boson with SU(2) isospin symmetry. As another system, we also consider a charm (bottom) quark embedded in quark matter as a heavy impurity fermion with SU(3) color symmetry. We suppose a vector current interaction with SU($n$) symmetry ($n \ge 2$) for the fermion composing the Fermi surface and the embedded heavy impurity particle, and calculate the scattering amplitude perturbatively for the small coupling constant up to one-loop level. We obtain that the scattering amplitude has a logarithmic enhancement in the large mass limit of the heavy impurity particle, and show that the perturbative calculation breaks down for any small coupling constant in this limit.

description: Generation of perpendicular effective magnetic field or perpendicular spins (σz) is central for the development of energy-efficient, scalable, and external-magnetic-field-free spintronic memory and computing technologies. Here, we report the first identification and the profound impacts of a significant effective perpendicular magnetic field that can arise from asymmetric current spreading within magnetic microstrips and Hall bars. This effective perpendicular magnetic field can exhibit all the three characteristics that have been widely assumed in the literature to "signify" the presence of a flow of σz, i.e., external-magnetic-field-free current switching of uniform perpendicular magnetization, a sin2ϕ-dependent contribution in spin-torque ferromagnetic resonance signal of in-plane magnetization (ϕ is the angle of the external magnetic field with respect to the current, and a ϕ-independent but field-dependent contribution in the second harmonic Hall voltage of in-plane magnetization. This finding suggests that it is critical to include current spreading effects in the analyses of various spin polarizations and spin-orbit torques in magnetic heterostructure. Technologically, our results provide perpendicular effective magnetic field induced by asymmetric current spreading as a novel, universally accessible mechanism for efficient, scalable, and external-magnetic-field-free magnetization switching in memory and computing technologies.

description: In this thesis, first we present the original polar codes. We describe the basic polarization effect and present an efficient recursive formula to compute the best choices for frozen bits in the case of the binary erasure channel. Both the encoder and the decoder have log-linear complexity. We highlight that, by using the same construction as in binary polar codes, we can create polarized extreme (perfect or useless) channels for any prime-input channel.

Then, we indicate the characteristics of the matrices that achieve channel polarization. We present a strict method that allows us to recursively construct generator matrices based on the Pascal matrix for prime alphabets. We observe their characteristics and properties.

Finally, using the above-mentioned technique, we develop a new ternary kernel and an encoder and successive cancellation decoder with  log-linear complexity. We also construct  formulas that efficiently calculate the optimal choice of frozen symbols for a ternary erasure channel. It is shown that our construction polarizes the capacities of the channels relatively faster in comparison to the conventional polar construction. The latter is illustrated by considering the error-correction capability of both the conventional Polar code and our proposed code and simulating the symbol error rate for the TEC.

description: Using a particular Hilbert space representation of minimum-length deformed quantum mechanics, we show that the resolution of the wave-function singularities for strongly attractive potentials, as well as cosmological singularity in the framework of a minisuperspace approximation, is uniquely tied to the fact that this sort of quantum mechanics implies the reduced Hilbert space of state-vectors consisting of the functions nonlocalizable beneath the Planck length. (Corrections to the Hamiltonian do not provide such an universal mechanism for avoiding singularities.) Following this discussion, as a next step we take a critical view of the meaning of wave-function in such a quantum theory. For this reason we focus on the construction of current vector and the subsequent continuity equation. Some issues gained in the framework of this discussion are then considered in the context of field theory. Finally, we discuss the classical limit of the minimum-length deformed quantum mechanics and its dramatic consequences.
