description: Amphiphilic molecules and their self-assembled structures have long been the target of extensive research due to their potential applications in fields ranging from materials design to biomedical and cosmetic applications. Increasing demands for functional complexity have been met with challenges in biochemical engineering, driving researchers to innovate in the design of new amphiphiles. An emerging class of molecules, namely, peptide amphiphiles, combines key advantages and circumvents some of the disadvantages of conventional phospholipids and block-copolymers. Herein, we present new peptide amphiphiles comprised of an intrinsically disordered peptide conjugated to two variants of hydrophobic dendritic domains. These molecules termed intrinsically disordered peptide amphiphiles (IDPA), exhibit a sharp pH-induced micellar phase-transition from low-dispersity spheres to extremely elongated worm-like micelles. We present an experimental characterization of the transition and propose a theoretical model to describe the pH-response. We also present the potential of the shape transition to serve as a mechanism for the design of a cargo hold-and-release application. Such amphiphilic systems demonstrate the power of tailoring the interactions between disordered peptides for various stimuli-responsive biomedical applications.

description: We consider a curvaton scenario in which the late-time domination and the generation of the curvature perturbation is achieved by a non-oscillatory (NO) curvaton potential. Instead of considering the conventional curvaton oscillation, we consider ``weak trapping'' after preheating, which modifies the evolution of the curvaton density after preheating. The primordial isocurvature perturbation related to the curvaton is once converted into the fluctuation of the number density of the preheat field through inhomogeneous preheating. Then the evolution of the curvatons and the preheat field is controlled by the preheat-field number density. The density of these fields decreases slightly slower than the standard matter density which suggests that these fields will grow with time. Finally, the preheat field decays to reheat the Universe leaving behind the curvature perturbation. In our scenario the task of the standard curvaton is not executed solely by the curvaton itself but is partially shared with the preheat field. NO curvatons can be considered as the hybrid version of the quintessential inflationary model.

description: The introduction of alkali catalyst during hydrothermal liquefaction (HTL) improves conversion and allows the aqueous liquid product to be used as gasification feedstock. This study investigates the effect of reaction temperature (240–300°C), sawdust mass fraction (9.1–25%) and reaction time (0–60 min) during K2CO3-catalytic HTL of pine sawdust. The highest biomass conversion (75.2% carbon conversion and 83.0% mass conversion) was achieved at a reaction temperature of 270°C, 9.1% sawdust mass fraction and 30 min reaction time; meanwhile, the maximum aqueous product (AP) yield (69.0% carbon yield and 73.5% mass yield) was found at a reaction temperature of 300°C, 9.1% sawdust mass fraction and 60 min reaction time. Based on the main experimental results, models for carbon and mass yields of the products were developed according to face-centered central composite design using response surface methodology. Biomass conversion and product yields had a positive correlation with reaction temperature and reaction time, while they had an inverse correlation with sawdust mass fraction. Further investigation of the effects of biomass/water and biomass/K2CO3 ratios revealed that both high water loading and high K2CO3 loading enhanced conversion and AP yield.

description: A sterile neutrino in the $3+1$ scheme, where the sterile accounts for neutrino anomalies not explained solely by the weak active neutrinos, arises as a natural source for the breaking of the $μ-τ$ symmetry suggested by oscillation neutrino data. We explore the predictions for the Dirac CP phases in this scenario, with and without sterile neutrino decay, and show that current limits on $δ_{CP}$ suggest a normal hierarchy and a lightest neutrino scale below 0.1~eV as the most plausible explanation for that, when Majorana phases are null. Other Dirac phases turn out to be non zero as well.

description: Objective: To investigate, record and study diabetic retinopathy in patients with gestational diabetes. Materials and Methods: 152 patients with gestational diabetes according to the "International Association of Diabetes in Pregnancy Study Groups" criteria were prospectively examined. The examination included recording of visual acuity with Snellen's chart, control of anterior eye chamber under the slit lamp, retinal biomicroscopy after mydriasis and optical coherence tomography. For statistical analysis the SPSS 23 software was selected. Results: No patient was found to have fundoscopic defects consistent with diabetic retinopathy. No pathologic findings of the anterior chamber were observed under slit lamp examination. 21,6% of patients were found to have some refractive error. Of these patients 87,5% had myopia, 12,5% hyperopia and 37,5% astigmatism. Conclusion: Patients with gestational diabetes do not exhibit ophthalmic findings consistent with diabetic retinopathy. Gestational diabetes does not seem to influence the visual acuity nor the refractional ability of pregnant women.

For this model we construct a Bäcklund transformation and prove its basic properties: canonicity, commutativity and spectrality. The Bäcklund transformation can be also viewed as a discretized time dynamics. Two Lax matrices are used: of order 2 and of order 2n+2, which are mutually dual, sharing the same spectral curve.

description: We study the effect of physical aging on the mechanical properties of a model polymer glass using molecular dynamics simulations. The creep compliance is determined simultaneously with the structural relaxation under a constant uniaxial load below yield at constant temperature. The model successfully captures universal features found experimentally in polymer glasses, including signatures of mechanical rejuvenation. We analyze microscopic relaxation timescales and show that they exhibit the same aging characteristics as the macroscopic creep compliance. In addition, our model indicates that the entire distribution of relaxation times scales identically with age. Despite large changes in mobility, we observe comparatively little structural change except for a weak logarithmic increase in the degree of short-range order that may be correlated to an observed decrease in aging with increasing load.

description: We study the binding energies of spin-isospin saturated nuclei with nucleon number $8 \le A \le 100$ in semiclassical Monte Carlo many-body simulations. The model Hamiltonian consists of, (i) nucleon kinetic energy, (ii) a nucleon-nucleon interaction potential, and (iii) an effective Pauli potential which depends on density. The basic ingredients of the nucleon-nucleon potential are, a short-range repulsion, and a medium-range attraction. Our results demonstrate that one can always expect to obtain the empirical binding energies for a set of nuclei by introducing a proper density dependent Pauli potential. The present work suggests a simple, pragmatic procedure for modelling a set of nuclei calibrated by the empirical binding energies for a given NN interaction potential. Then, each set of modelled nuclei can be tested by studying other properties of nuclei in semiclassical simulations.

Effect of antiferromagnetic exchange interactions on the Glauber dynamics of one-dimensional Ising models

description: We study the effect of antiferromagnetic interactions on the single spin-flip Glauber dynamics of two different one-dimensional (1D) Ising models with spin $\pm 1$. The first model is an Ising chain with antiferromagnetic exchange interaction limited to nearest neighbors and subject to an oscillating magnetic field. The system of master equations describing the time evolution of sublattice magnetizations can easily be solved within a linear field approximation and a long time limit. Resonant behavior of the magnetization as a function of temperature (stochastic resonance) is found, at low frequency, only when spins on opposite sublattices are uncompensated owing to different gyromagnetic factors (i.e., in the presence of a ferrimagnetic short range order). The second model is the axial next-nearest neighbor Ising (ANNNI) chain, where an antiferromagnetic exchange between next-nearest neighbors (nnn) is assumed to compete with a nearest-neighbor (nn) exchange interaction of either sign. The long time response of the model to a weak, oscillating magnetic field is investigated in the framework of a decoupling approximation for three-spin correlation functions, which is required to close the system of master equations. The calculation, within such an approximate theoretical scheme, of the dynamic critical exponent z, defined as ${1/τ} \approx ({1/ ξ})^z$ (where τis the longest relaxation time and ξis the correlation length of the chain), suggests that the T=0 single spin-flip Glauber dynamics of the ANNNI chain is in a different universality class than that of the unfrustrated Ising chain.

description: We investigate the complexity=volume proposal in the case of Janus AdS$_3$ geometries, both at zero and finite temperature. The leading contribution coming from the Janus interface is a logarithmic divergence, whose coefficient is a function of the dilaton excursion. In the presence of the defect, complexity is no longer topological and becomes temperature-dependent. We also study the time evolution of the extremal volume for the time-dependent Janus BTZ black hole. This background is not dual to an interface but to a pair of entangled CFTs with different values of the couplings. At late times, when the equilibrium is restored, the couplings of the CFTs do not influence the complexity rate. On the contrary, the complexity rate for the out-of-equilibrium system is always smaller compared to the pure BTZ black hole background.

description: In this paper we present a new algebraic structure (a super hyperbolic system in our terminology) for finite quantum systems, which is a generalization of the usual one in the two-level system. It fits into the so-called generalized Pauli matrices, so they play an important role in the theory. Some deep relation to the modified Bessel functions of integer order is pointed out. By taking a skillful limit finite quantum systems become quantum mechanics on the circle developed by Ohnuki and Kitakado.

Moveability and Collision Analysis for Fully-Parallel Manipulators

Publisher: name: arXiv
Year: 2007
Subjects: subject: Robotics (cs.RO)
subject: FOS: Computer and information sciences

description: The aim of this paper is to characterize the moveability of fully-parallel manipulators in the presence of obstacles. Fully parallel manipulators are used in applications where accuracy, stiffness or high speeds and accelerations are required \cite{Merlet:97}. However, one of its main drawbacks is a relatively small workspace compared to the one of serial manipulators. This is due mainly to the existence of potential internal collisions, and the existence of singularities. In this paper, the notion of free aspect is defined which permits to exhibit domains of the workspace and the joint space free of singularity and collision. The main application of this study is the moveability analysis in the workspace of the manipulator as well as path-planning, control and design.

The Lagrangian includes new higher derivative operators. We show that the higher derivative terms can be eliminated by introducing a set of auxiliary fields; this allows for convenient computation and makes the physical interpretation more transparent. Although the theory is unitary, it does not satisfy the usual analyticity conditions.

description: When constructing high-order schemes for solving hyperbolic conservation laws, the corresponding high-order reconstructions are commonly performed in characteristic spaces to eliminate spurious oscillations as much as possible. For multi-dimensional finite volume (FV) schemes, we need to perform the characteristic decomposition several times in different normal directions of the target cell, which is very time-consuming. In this paper, we propose a rotated characteristic decomposition technique which requires only one-time decomposition for multi-dimensional reconstructions. The rotated direction depends only on the gradient of a specific physical quantity which is cheap to calculate. This technique not only reduces the computational cost remarkably, but also controls spurious oscillations effectively. We take a third-order weighted essentially non-oscillatory finite volume (WENO-FV) scheme for solving the Euler equations as an example to demonstrate the efficiency of the proposed technique.

description: Nowadays, as cameras are rapidly adopted in our daily routine, images of documents are becoming both abundant and prevalent. Unlike natural images that capture physical objects, document-images contain a significant amount of text with critical semantics and complicated layouts. In this work, we devise a generic unsupervised technique to learn multimodal affinities between textual entities in a document-image, considering their visual style, the content of their underlying text and their geometric context within the image. We then use these learned affinities to automatically cluster the textual entities in the image into different semantic groups. The core of our approach is a deep optimization scheme dedicated for an image provided by the user that detects and leverages reliable pairwise connections in the multimodal representation of the textual elements in order to properly learn the affinities. We show that our technique can operate on highly varying images spanning a wide range of documents and demonstrate its applicability for various editing operations manipulating the content, appearance and geometry of the image.

Maternal Depressive Symptoms and Preschoolers’ Helping, Sharing, and Comforting: The Moderating Role of Child Attachment

Publisher: name: Taylor & Francis

description: Maternal depressive symptoms (MDS) are inconsistently associated with lower rates of child prosocial behavior. Studies typically examine prosocial behavior as a unitary construct rather than examining its multiple dimensions, and rarely consider how the quality of the parent-child relationship could influence this association. The current study examines whether the security of the parent-child attachment relationship moderates the association between MDS and children’s helping, sharing, and comforting behaviors. Participants were 164 low-income, majority African American mothers and their preschool-aged children recruited from Head Start centers. Mothers reported the frequency of depressive symptoms at baseline; child attachment security and helping, sharing, and comforting behavior were observationally assessed 5 to 8 months later. Moderation analyses revealed a positive main effect of security (but not MDS) on children’s comforting behavior, a main effect of MDS on sharing, and no main effects of MDS or security on children’s helping behaviors. Significant interactions between MDS and security predicted comforting and (marginally) helping behaviors, such that MDS were associated with both more helping and more comforting behavior only when children were more secure. No such interaction was observed for sharing. These findings suggest that children may adapt to maternal depressive symptoms in prosocial ways, but that this depends at least in part on the quality of the parent-child relationship, underscoring the importance of examining attachment quality as a moderator of parental influences on children’s social-emotional development. We discuss potential explanations for these findings, as well as their implications for intervention.

description: Phantom fields with negative kinetic energy are often plagued by the vacuum quantum instability in the ultraviolet region. We present a Lorentz-violating dark energy model free from this problem and show that the crossing of the cosmological constant boundary w=-1 to the phantom equation of state is realized before reaching a de Sitter attractor. Another interesting feature is a peculiar time-dependence of the effective Newton's constant; the magnitude of this effect is naturally small but may be close to experimental limits. We also derive momentum scales of instabilities at which tachyons or ghosts appear in the infrared region around the present Hubble scale and clarify the conditions under which tachyonic instabilities do not spoil homogeneity of the present/future Universe.

description: We study the dynamics of the critical two-dimensional fully-frustrated Ising model by means of Monte Carlo simulations. The dynamical exponent is estimated at equilibrium and is shown to be compatible with the value $z_c=2$. In a second step, the system is prepared in the paramagnetic phase and then quenched at its critical temperature $T_c=0$. Numerical evidences for the existence of logarithmic corrections in the aging regime are presented. These corrections may be related to the topological defects observed in other fully-frustrated models. The autocorrelation exponent is estimated to be $λ=d$ as for the Ising chain quenched at $T_c=0$.

description: The response of degree-correlated scale-free attractor networks to stimuli is studied. We show that degree-correlated scale-free networks are robust to random stimuli as well as the uncorrelated scale-free networks, while assortative (disassortative) scale-free networks are more (less) sensitive to directed stimuli than uncorrelated networks. We find that the degree-correlation of scale-free networks makes the dynamics of attractor systems different from uncorrelated ones. The dynamics of correlated scale-free attractor networks result in the effects of degree correlation on the response to stimuli.

description: We present the detections of shocked molecular hydrogen (H2) gas in near- and mid-infrared and broad CO in millimeter from the mixed-morphology supernova remnant (SNR) HB~3 (G132.7+1.3) using Palomar WIRC, the Spitzer GLIMPSE360 and WISE surveys, and HHSMT. Our near-infrared narrow-band filter H2 2.12 micron images of HB~3 show that both Spitzer IRAC and WISE 4.6 micron emission originates from shocked H2 gas. The morphology of H2 exhibits thin filamentary structures and a large scale of interaction sites between the HB~3 and nearby molecular clouds. Half of HB~3, the southern and eastern shell of the SNR, emits H2 in a shape of a "butterfly" or "W", indicating the interaction sites between the SNR and dense molecular clouds. Interestingly, the H2 emitting region in the southeast is also co-spatial to the interacting area between HB~3 and the H~II regions of the W3 complex, where we identified star-forming activity. We further explore the interaction between HB~3 and dense molecular clouds with detections of broad CO(3-2) and CO(2-1) molecular lines from the southern and southeastern shells along the H2 emitting region. The widths of the broad lines are 8-20 km/s; the detection of such broad lines is unambiguous, dynamic evidence of the interactions between the SNR and clouds. The CO broad lines are from two branches of the bright, southern H2 shell. We apply the Paris-Durham shock model to the CO line profiles, which infer the shock velocities of 20 - 40 km/s, relatively low densities of 10^{3-4} cm^{-3} and strong (>200 micro Gauss) magnetic fields.

A biomechanical investigation of blood flow occlusion achieved with the use of surgical pneumatic tourniquets
Creators: name: Breault, Martine
Publisher: name: University of British Columbia
Year: 2010

description: The use of the modern pneumatic surgical tourniquet has greatly facilitated orthopaedic limb surgery since its introduction. Overly high inflation pressures and improper application procedures have, however, resulted in occasional cutaneous, vascular and neuromuscular injuries. The present research models the mechanism of blood flow occlusion produced by a pneumatic cuff to determine safer inflation pressures and efficacious application procedures. A computerized data acquisition system using a biomedical pneumatic pressure sensor was utilized to measure surface and internal soft tissue pressures. Minimal occlusive cuff inflation pressures were determined by a series of pressure measurements on exsanguinated and non-exsanguinated limbs of normotensive subjects and patients. It was found that occlusion was achievable near patient diastolic pressure providing the cuff width was equal to or greater than the limb circumference. Analytical models were developed to understand the mechanism causing arrest of blood flow. To illustrate the application of the model and analytic techniques, two commercial tourniquet cuffs were analysed and tested to improve their design. Wider, thinner, softer and shape-matching cuff designs were suggested for future manufacture.
title: Online Content Generation in Mobile Applications - Adaptation and Personalization for Location-based Game Systems
Creators: name: Tregel, Thomas
Publisher: name: UNSPECIFIED

description: Location-aware mobile applications like navigation services or fitness trackers are inherently incorporated into our everyday life. The success of Ingress and Pokémon GO popularized the genre of location-based games, even indicating positive health effects for avid players that voluntarily cover large distances. However, the inconsistent and area-dependent supply of playable content, combined with superficial cooperation mechanisms, pose a considerable challenge for novel games in this genre. Furthermore, a suitable content generation based on real-world location data is complicated by the heterogeneity of populated areas. Continuously, in these movement-based games an inflexible mobility integration penalizes players deviating from the game’s intended style of play. Online procedural content generation, which creates content during run-time, is well suited for such scenarios. In numerous application domains, online content generation is utilized based on individual scenario parameters and contextual user data, providing personalized outcomes. But the optimization of content availability based on real-world location data, combined with a dynamic online generation, remains an open research challenge. In this thesis, we design and implement automatic location-based content generation mechanisms as our first contribution, which address the aforementioned challenge. We develop an approach to identify suitable content locations and procedurally derive game areas. Consequently, we enable cooperation concepts by game area coupling, providing distinct game areas with similar urban characteristics, even in heterogeneous areas. Since movement is the main characteristic of such games, we propose a mobility personalization strategy as our second contribution. This incorporates a player routing approach in urban scenarios focusing on guided virtual reward optimization. On this basis, we develop a run-time mobility detection utilizing accumulated smartphone sensor data as our third contribution. To support this decision-making process, we employ a combination of accelerometer and location sensor readings to overcome the limitations of individual data sources for specific mobility types. Finally, based on our developed GeoVis prototype, we conduct an extensive evaluation of our contributions. Therefore, we assess the effectiveness of our content approach under varying ambient conditions. We show that our location-based content generation leads to a reliable and flexible content selection in inhabited regions. Additionally, we demonstrate the utilization of route planning and automatic mobility detection as suitable mobility personalization strategies. In summary, we show that our contributions allow novel location-based game systems to create content worldwide and adapt to application-specific area and mobility characteristics by examining user mobility data during run-time.

description: Shock and release temperatures in Mo were calculated, taking account of heating from plastic flow predicted using the Steinberg-Guinan model. Plastic flow was calculated self-consistently with the shock jump conditions: this is necessary for a rigorous estimate of the locus of shock states accessible. The temperatures obtained were significantly higher than predicted assuming ideal hydrodynamic loading. The temperatures were compared with surface emission spectrometry measurements for Mo shocked to around 60GPa and then released into vacuum or into a LiF window. Shock loading was induced by the impact of a planar projectile, accelerated by high explosive or in a gas gun. Surface velocimetry showed an elastic wave at the start of release from the shocked state; the amplitude of the elastic wave matched the prediction to around 10%, indicating that the predicted flow stress in the shocked state was reasonable. The measured temperatures were consistent with the simulations, indicating that the fraction of plastic work converted to heat was in the range 70-100% for these loading conditions.

description: The combination of SCR and DPF devices in one system (so called SCRF) enables a very compact design and has already found its way into commercial application for passenger cars. In the case of heavy-duty and non-road applications, the design and control of the SCRF heavily depends on the interactions between SCR and DPF functionalities taking place in the device. Indicative examples are the competitive NO2 consumption by the SCR and soot reactions or the trade-off that needs to be made when choosing the optimal washcoat amount to balance between de-NOx performance, filtration efficiency and pressure drop behavior. In addition, another aspect of the competitive interactions is the alteration of the mass-transfer characteristics by the soot and/or ash presence which may impact NOx conversion. Based on the above, the SCRF efficiency is not a simple superimposition of the individual SCR and DPF efficiencies. The interactions between the two functionalities is a crucial aspect which needs to be understood in order to enable proper component design and optimal system performance. In the frame of the present thesis, the above phenomena are analytically studied, discussed and explained by means of multi-scale experimental testing and mathematical modeling.
description: Ο συνδυασμός ενός καταλύτη επιλεκτικής αναγωγής (SCR) κι ενός φίλτρου αιθάλης (DPF) σε μία συσκευή (γνωστή ως SCRF) επιτυγχάνει τη μείωση του απαιτούμενου όγκου του συστήματος κι έχει ήδη βρει εμπορική εφαρμογή σε επιβατικά αυτοκίνητα. Στην περίπτωση των βαρέων επαγγελματικών και εκτός δρόμου οχημάτων, ο σχεδιασμός και ο έλεγχος του φίλτρου SCRF εξαρτάται έντονα από τις αλληλεπιδράσεις μεταξύ των λειτουργιών SCR και DPF. Χαρακτηριστικά παραδείγματα είναι η ανταγωνιστική κατανάλωση του NO2 ανάμεσα στις αντιδράσεις αναγωγής NOx και οξείδωσης της αιθάλης ή ο συμβιβασμός κατά την εκλογή της ποσότητας καταλυτικού υλικού ώστε να ισοσκελιστεί η απόδοση ανάμεσα στην αναγωγή των NOx, της πτώση πίεσης και του βαθμού διήθησης. Επιπροσθέτως, μία άλλη όψη των αλληλεπιδράσεων αυτών είναι η μεταβολή των χαρακτηριστικών μεταφοράς μάζας από την ύπαρξη ενός στρώματος αιθάλης ή/και στάχτης η οποία μπορεί να επηρεάσει το βαθμό αναγωγής NOx. Βάσει των παραπάνω, ο βαθμός απόδοσης του SCRF δεν είναι μία απλή υπέρθεση των επιμέρους αποδόσεων των συσκευών SCR και DPF. Οι αλληλεπιδράσεις μεταξύ των δύο αυτών λειτουργιών αποτελούν μία κρίσιμη πτυχή η οποία πρέπει να κατανοηθεί ώστε να επιτευχθεί ορθός σχεδιασμός και βέλτιστη απόδοση του συστήματος. Στο πλαίσιο της παρούσας διδακτορικής διατριβής, τα παραπάνω φαινόμενα μελετώνται, αναλύονται και εξηγούνται διαμέσου πειραματικών δοκιμών και μαθηματικής μοντελοποίησης.

description: Let $M^{4n}$ be a complete quaternionic Kähler manifold with scalar curvature bounded below by $-16n(n+2)$. We get a sharp estimate for the first eigenvalue $λ_1(M)$ of the Laplacian which is $λ_1(M)\le (2n+1)^2$. If the equality holds, then either $M$ has only one end, or $M$ is diffeomorphic to $\mathbb{R}\times N$ with N given by a compact manifold. Moreover, if $M$ is of bounded curvature, $M$ is covered by the quaterionic hyperbolic space $\mathbb{QH}^n$ and $N$ is a compact quotient of the generalized Heisenberg group. When $λ_1(M)\ge \frac{8(n+2)}3$, we also prove that $M$ must have only one end with infinite volume.
