Lattice models for ballistic aggregation in one-dimension

description: We propose two lattice models in one dimension, with stochastically hopping particles which aggregate on contact. The hops are guided by "velocity rates" which themselves evolve according to the rules of ballistic aggregation as in a sticky gas in continuum. Our lattice models have both velocity and density fields and an appropriate real time evolution, such that they can be compared directly with event driven molecular dynamics (MD) results for the sticky gas. We demonstrate numerically that the long time and large distance behavior of the lattice models are identical to that of the MD, and some exact results known for the sticky gas. In particular, the exactly predicted form of the non-Gaussian tail of the velocity distribution function is clearly exhibited. This correspondence of the lattice models and the sticky gas in continuum is nontrivial, as the latter has a deterministic dynamics with local kinematic constraint, in contrast with the former; yet the spatial velocity profiles (with shocks) of the lattice models and the MD have striking match.

description: Three-dimensional (3-D) synthetic aperture radar (SAR) is widely used in many security and industrial applications requiring high-resolution imaging of concealed or occluded objects. The ability to resolve intricate 3-D targets is essential to the performance of such applications and depends directly on system bandwidth. However, because high-bandwidth systems face several prohibitive hurdles, an alternative solution is to operate multiple radars at distinct frequency bands and fuse the multiband signals. Current multiband signal fusion methods assume a simple target model and a small number of point reflectors, which is invalid for realistic security screening and industrial imaging scenarios wherein the target model effectively consists of a large number of reflectors. To the best of our knowledge, this study presents the first use of deep learning for multiband signal fusion. The proposed network, called kR-Net, employs a hybrid, dual-domain complex-valued convolutional neural network (CV-CNN) to fuse multiband signals and impute the missing samples in the frequency gaps between subbands. By exploiting the relationships in both the wavenumber domain and wavenumber spectral domain, the proposed framework overcomes the drawbacks of existing multiband imaging techniques for realistic scenarios at a fraction of the computation time of existing multiband fusion algorithms. Our method achieves high-resolution imaging of intricate targets previously impossible using conventional techniques and enables finer resolution capacity for concealed weapon detection and occluded object classification using multiband signaling without requiring more advanced hardware. Furthermore, a fully integrated multiband imaging system is developed using commercially available millimeter-wave (mmWave) radars for efficient multiband imaging.

Mixing of CNO-cycled matter in pulsationally and magnetically active massive stars

description: We report on the abundances of helium, carbon, nitrogen and oxygen in a larger sample of Galactic massive stars of ~7-20 M_sun near the main sequence, composed of apparently normal objects, pulsators of beta-Cephei- and SPB-type, and magnetic stars. High-quality spectra are homogeneously analysed using sophisticated non-LTE line-formation and comprehensive analysis strategies. All the stars follow a previously established tight trend in the N/C-N/O ratio and show normal helium abundances, tracing the nuclear path of the CNO-cycles quantitatively. A correlation of the strength of the mixing signature with the presence of magnetic fields is found. In conjunction with low rotation velocities this implies that magnetic breaking is highly efficient for the spin-down of some massive stars. We suggest several objects for follow-up spectropolarimetry, as the mixing signature indicates a possible magnetic nature of these stars.

description: This paper presents an approach to a time-dependent variant of the concept of vector field topology for 2-D vector fields. Vector field topology is defined for steady vector fields and aims at discriminating the domain of a vector field into regions of qualitatively different behaviour. The presented approach represents a generalization for saddle-type critical points and their separatrices to unsteady vector fields based on generalized streak lines, with the classical vector field topology as its special case for steady vector fields. The concept is closely related to that of Lagrangian coherent structures obtained as ridges in the finite-time Lyapunov exponent field. The proposed approach is evaluated on both 2-D time-dependent synthetic and vector fields from computational fluid dynamics.

description: Detection of magnetic-type ($B$-type) polarization in the Cosmic Microwave Background (CMB) radiation plays a crucial role in probing the relic gravitational wave (RGW) background. In this paper, we propose a new method to deconstruct a polarization map on an incomplete sky in real space into purely electric and magnetic polarization type maps, ${\mathcal{E}}(\hatγ)$ and ${\mathcal{B}}(\hatγ)$, respectively. The main properties of our approach are as follows: Firstly, the fields ${\mathcal{E}}(\hatγ)$ and ${\mathcal{B}}(\hatγ)$ are constructed in real space with a minimal loss of information. This loss of information arises due to the removal of a narrow edge of the constructed map in order to remove various numerical errors, including those arising from finite pixel size. Secondly, this method is fast and can be efficiently applied to high resolution maps due to the use of the fast spherical harmonics transformation. Thirdly, the constructed fields, ${\mathcal{E}}(\hatγ)$ and ${\mathcal{B}}(\hatγ)$, are scalar fields. For this reason various techniques developed to deal with temperature anisotropy maps can be directly applied to analyze these fields. As a concrete example, we construct and analyze an unbiased estimator for the power spectrum of the $B$-mode of polarization $C_{\ell}^{BB}$. Basing our results on the performance of this estimator, we discuss the RGW detection ability of two future ground-based CMB experiments, QUIET and POLARBEAR.

description: The major problem in the cosmological nucleosynthesis is the evaluation of the reaction rate. The present scenario is that the standard thermonuclear function in the Maxwell-Boltzmann form is evaluated by using various techniques. The Maxwell-Boltzmannian approach to nuclear reaction rate theory is extended to cover Tsallis statistics (Tsallis, 1988) and more general cases of distribution functions. The main purpose of this paper is to investigate in some more detail the extended reaction probability integral in the equilibrium thermodynamic argument and in the cut-off case. The extended reaction probability integrals will be evaluated in closed form for all convenient values of the parameter by means of residue calculus. A comparison of the standard reaction probability integrals with the extended reaction probability integrals is also done.

description: Multiple-input-multiple-output (MIMO) millimeter-wave (mmWave) sensors for synthetic aperture radar (SAR) and inverse SAR (ISAR) address the fundamental challenges of cost-effectiveness and scalability inherent to near-field imaging. In this paper, near-field MIMO-ISAR mmWave imaging systems are discussed and developed. The rotational ISAR (R-ISAR) regime investigated in this paper requires rotating the target at a constant radial distance from the transceiver and scanning the transceiver along a vertical track. Using a 77GHz mmWave radar, a high resolution three-dimensional (3-D) image can be reconstructed from this two-dimensional scanning taking into account the spherical near-field wavefront. While prior work in literature consists of single-input-single-output circular synthetic aperture radar (SISO-CSAR) algorithms or computationally sluggish MIMO-CSAR image reconstruction algorithms, this paper proposes a novel algorithm for efficient MIMO 3-D holographic imaging and details the design of a MIMO R-ISAR imaging system. The proposed algorithm applies a multistatic-to-monostatic phase compensation to the R-ISAR regime allowing for use of highly efficient monostatic algorithms. We demonstrate the algorithm's performance in real-world imaging scenarios on a prototyped MIMO R-ISAR platform. Our fully integrated system, consisting of a mechanical scanner and efficient imaging algorithm, is capable of pairing the scanning efficiency of the MIMO regime with the computational efficiency of single pixel image reconstruction algorithms.

We show that the proof of the main theorem, Theorem 2.6 in [Phys. Lett. A 373 (2009) 3610] is not complete. Therefore the generalization of Nielsen's theorem to mixed states still remains an open problem.

description: Using the formalism of Lyapunov potential function it is shown that the stability principles for biomass in the ecosystem and for employment in economics are mathematically similar. The ecosystem is found to have a stable and an unstable stationary state with high (forest) and low (grasslands) biomass, respectively. In economics, there is a stable stationary state with high employment, which corresponds to mass production of conventional goods sold at low cost price, and an unstable stationary state with lower employment, which corresponds to production of novel goods appearing in the course of technological progress. An additional stable stationary state is described for economics, the one corresponding to very low employment in production of life essentials such as energy and raw materials. In this state the civilization currently pays 10% of global GDP for energy produced by a negligible minority of the working population (currently ~0.2%) and sold at prices greatly exceeding the cost price by 40 times. It is shown that economic ownership over energy sources is equivalent to equating measurable variables of different dimensions (stores and fluxes), which leads to effective violation of the laws of energy and matter conservation.

Siren Songs and Echo’s Response
Creators: name: Borbach, Christoph
Publisher: name: On_Culture
Year: 2016

description: In contrast to phonographical recording, storage, and reproduction of the voice, most media theories, especially prominent media theories of the human voice, neglected the aspect of synthesizing human-like voices by non-human means. This paper takes this lacuna as a starting point for an inquiry into the media theory of (non)human voices under the premise that the epistemological difference between techn(olog)ical voice production and its mere re-production is illuminated by the mythological motifs of the Sirens and Echo, respectively. Interestingly, the interconnection between terror and tempting nonhuman voices, which is implemented in the cultural imaginary through the Sirens’ song, can be identified in the media history of speech synthesis, which challenges the idea(l) of the human voice as an anthropological constant. The main concerns here are to re-read the critique of Derrida’s Of Grammatology and other theories of the human voice in the light of speech synthesis and show how the oft-used term ‘disembodied voice’ is inadequate when it comes to describing phonographical, radiophonic, and telephonic hearing situations.

description: We report the detection of the CO J=1-0 emission line in [H89]1821+643, one of the most optically luminous QSOs in the local Universe and a template ULIRG-to-QSO transition object, located in a rich cool-core cluster at z=0.297. The CO emission is likely to be extended, highly asymmetric with respect to the center of the host elliptical where the QSO resides, and corresponds to a molecular gas mass of ~ 8.0 x 10^{9} M_sun. The dynamical mass enclosed by the CO line emission region could amount up to ~ 1.7x10^{12} M_sun (80% of the total mass of the elliptical host). The bulk of the CO emission is located at ~9 kpc south-east from the nuclei position, and close to a faint optical structure, suggesting that the CO emission could either represent a gas-rich companion galaxy merging with the elliptical host or a tail-like structure reminiscent of a previous interaction. We argue that the first scenario is more likely given the large masses implied for the CO source, which would imply a highly asymmetrical elliptical host. The close alignment between the CO emission major axis and the radio-plume suggests a possible role of the latter excitation of the ambient gas reservoir. The stacking technique was used to search for CO emission and 3mm continuum emission from galaxies in the surrounding cluster, however no detection was found either toward individual galaxies or the stacked ensemble of galaxies, with a 3 sigma limit of < 1.1x10^9 M_sun for the molecular gas.

description: We have used multi-band imaging to investigate the nature of the extreme starburst environment in Haro 11 galaxy. The central starburst region has been observed in 8 HST wavebands and at 2.16 micron at the ESO-VLT. We constructed integrated spectral energy distributions (SEDs) for about 200 star clusters and compared them with single stellar population models in order to derive ages, masses and extinctions of thestar clusters. The present starburst has lasted for 40 Myr, and shows a peak of cluster formation only 3.5 Myr old. With such an extremely young cluster population, Haro 11 represents a unique opportunity to investigate the youngest phase of the cluster formation process and evolution in starburst systems. Extinction tends to diminish as function of the cluster age, but the spread is large and for clusters in partial embedded phases (< 5 Myr). A fraction of low-mass (> 10^4 Msun), very young (1-3 Myr) clusters is missing, either because they are embedded inthe parental molecular cloud and heavily extinguished, or because of blending. Almost half of the cluster sample is affected by flux excesses at wavelengths 8000 Åwhich cannot be explained by simple stellar evolutionary models. Fitting SED models over all wavebands leads to systematic overestimates of cluster ages and incorrect masses for the stellar population supplying the light in these clusters. We show that the red excess affects also the HST F814W filter, which is typically used to constrain cluster physical properties. The clusters which show the red excess are younger than 40 Myr; we propose possible physical explanations for the phenomenon. Finally, we estimate that Haro 11 hasproduced bound clusters at a rate almost a factor of 10 higher than the massive and regular spirals, like the Milky Way. (Abriged)

description: In an armchair carbon nanotube pn junction the p- and n- regions are separated by a region of a Mott insulator, which can backscatter electrons only in pairs. We predict a quantum-critical behavior in such a pn junction. Depending on the junction's built-in electric field E, its conductance G scales either to zero or to the ideal value G=4e^2/h as the temperature T is lowered. The two types of the G(T) dependence indicate the existence, at some special value of E, of an intermediate quantum critical point with a finite conductance G<4e^2/h. This makes the pn junction drastically different from a simple barrier in a Luttinger liquid.

description: This is the second of two papers devoted to the perturbative computation of the ghost and gluon propagators in SU(3) Lattice Gauge Theory. Such a computation should enable a comparison with results from lattice simulations in order to reveal the genuinely non-perturbative content of the latter. The gluon propagator is computed by means of Numerical Stochastic Perturbation Theory: results range from two up to four loops, depending on the different lattice sizes. The non-logarithmic constants for one, two and three loops are extrapolated to the lattice spacing $a \to 0$ continuum and infinite volume $V \to \infty$ limits.

description: In this paper, we investigate novel data collection and training techniques towards improving classification accuracy of non-moving (static) hand gestures using a convolutional neural network (CNN) and frequency-modulated-continuous-wave (FMCW) millimeter-wave (mmWave) radars. Recently, non-contact hand pose and static gesture recognition have received considerable attention in many applications ranging from human-computer interaction (HCI), augmented/virtual reality (AR/VR), and even therapeutic range of motion for medical applications. While most current solutions rely on optical or depth cameras, these methods require ideal lighting and temperature conditions. mmWave radar devices have recently emerged as a promising alternative offering low-cost system-on-chip sensors whose output signals contain precise spatial information even in non-ideal imaging conditions. Additionally, deep convolutional neural networks have been employed extensively in image recognition by learning both feature extraction and classification simultaneously. However, little work has been done towards static gesture recognition using mmWave radars and CNNs due to the difficulty involved in extracting meaningful features from the radar return signal, and the results are inferior compared with dynamic gesture classification. This article presents an efficient data collection approach and a novel technique for deep CNN training by introducing ``sterile'' images which aid in distinguishing distinct features among the static gestures and subsequently improve the classification accuracy. Applying the proposed data collection and training methods yields an increase in classification rate of static hand gestures from $85\%$ to $93\%$ and $90\%$ to $95\%$ for range and range-angle profiles, respectively.

Flexible low-cost wireless temperature sensor using thermoresponsive Y5V capacitor chips
Creators: name: Patel, Ronish
Publisher: name: University of British Columbia
Year: 2020

description: Temperature sensing is one of the most important abilities for monitoring and controlling thermal behaviors of target objects or environments, and the capability of its wireless reading largely expands the potential application areas. For example, biomedical and environmental applications are some of the promising areas for wireless temperature sensors. The use of inductor-capacitor (LC) resonant-tank circuits in which the capacitance or the inductance is designed to vary with temperature, is an advantageous approach for wireless temperature sensing given its reliable frequency-based reading and no requirement for having internal power sources. Type Y5V multilayer dielectric capacitors, commercially available in low-cost (e.g., ~$0.01-0.1/chip) surface-mount chips, exhibit significant capacitance variations over a wide range of temperatures (-30 to +85 ℃). Such capacitors can serve as the sensing elements in LC-tank circuits for frequency-based wireless temperature reading. The current work designs, fabricates, and demonstrates the first proof-of-concept device of a flexible wireless sensor that uses Y5V capacitor chips in combination with planar inductive coils microfabricated on thin polymer film, forming LC-tank-based devices. The physical flexibility and disposable nature of the devices makes them suitable for medical/healthcare applications, e.g., continuous remote monitoring of patient’s body temperature and feedback control of clinical hyperthermia treatments for various cancer therapies. This research presents the design, fabrication, and experimental validation of two prototype passive wireless LC temperature sensors of varying dimensions. The larger sized (20 mm²) sensor reported has a frequency response of 106-150KHz/℃ and a resonant frequency of 152 MHz at room temperature. Whereas, the miniature (~6 mm2) sized sensor reported demonstrates a frequency response of 77-119KHz/℃ and a resonant frequency of 1.5 MHz at room temperature. Moreover, a low-cost impedance analyzer is developed in this work. It consists of Raspi 3 host device and a Digilent PmodIA impedance analyzer has a low error of ~4% as compared to the Agilent network analyzer. The new analyzer is demonstrated and experimentally validated.
Radiation from an Oscillating Dipole in the Presence of Photon-Sector CPT and Lorentz Violation

description: We examine one of the standard loci for studying electromagnetic wave emission -- the radiation from an oscillating electric dipole -- in a model in which the electromagnetic sector is modified to include novel CPT- and Lorentz-violating propagation effects involving a preferred axial vector background. We evaluate the vacuum-birefringent radiation fields, including nonperturbative terms where appropriate. In general, the energy-momentum carried by the fields in this model is known to have a complicated nonperturbative structure, which cannot be captured by naive power series expansions in the components of the preferred background vector. However, we nevertheless find that at the lowest nontrivial orders, there are actually no modifications to the Larmor expressions for the energy-momentum emission.

description: It allows any two parties that are either both on the same network or connected via the internet to transfer the contents of a file based on a particular sequence of words. Peer discovery happens via multicast DNS if both peers are on the same network or via entries in the distributed hash table (DHT) of the InterPlanetary File-System (IPFS) if both peers are connected across network boundaries. As soon as a connection is established, the word sequence is used as the input for a password-authenticated key exchange (PAKE) to derive a strong session key. This session key authenticates the peers and encrypts any subsequent communication. It is found that the decentralized approach to peer-to-peer file transfer can keep up with established centralized tools while eliminating the reliance on centralized service providers.
KALUZA-KLEIN TILTED COSMOLOGICAL MODEL IN LYRA GEOMETRY COUPLED WITH AND WITHOUT MAGNETIC FIELD

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: In this paper we have investigated Kaluza-Klein Tilted Bianchi type –I cosmological model in
the presence as well as in the absence of magnetic field by the frame work of Lyra geometry.
Exact solutions to the field equations are derived when the metric potentials are functions of
cosmic time only.
From the physical and geometrical properties of the solutions we find that in the absence of mag
netic field pressure,energy density,heat conduction,scalar expansion and tilt angles are constant
initially at T=0 and decreases as cosmic time increase.
Due to the presence of magnetic field tilt angle and heat conduction vectors are initially constant
and rapidly increases when the cosmic time of universe increase.

The global Peccei-Quinn symmetry under which exotic fermions are charged solves the strong CP problem. Within our general proposal, various setups can be distinguished by probing the axion-to-photon coupling at helioscopes and haloscopes. We also comment on axion dark-matter production in the early Universe.

description: The linear transient response of a two-level system coupled with an environmental system is studied under correlated and factorized initial conditions. We find that the transient response in these cases differs significantly from each other, especially for strong system-environment interaction at intermediate temperatures. This means that it is necessary to pay attention to the initial conditions chosen when analyzing experiments on transient linear response, because the conventional factorized initial condition results in an incorrect response, in which the quantum correlation between the relevant system and the environmental system is disregarded.

MATHEMATICAL MODELING OF FISH  POPULATION GROWTH WITH HARVESTING

description: In this research work, we proposed and analyzed a mathematical model to study the dynamics of a fishery
resource system in an aquatic environment that consists of two zones: a free fishing zone and a reserve
zone where fishing is strictly prohibited. Biological and bionomic equilibria of the system are obtained,
and  the existence of possible steady states, along with their local and global stability, is discussed.   It is
shown  that  even  if  fishery  is  exploited  continuously  in  the  unreserved  zone,  fish  populations  can  be
maintained  at  an  appropriate  equilibrium  level in  the  habitat.  We  then  examine  the  possibilities  of  the
existence of bionomic equilibrium.  An optimal harvesting policy is also discussed using the Pantryagin’s
Maximum  Principle.  Numerical  simulations  with  MATLAB  have  been  performed  to  study  the  effects  of
various parameters on the dynamics of the population biomass.

description: We consider the influence of a resonant control field on weak localization of light in ultracold atomic ensembles. Both steady-state and pulsed light excitation are considered. We show that the presence of a control field essentially changes the type of interference effects which occur under conditions of multiple scattering. For example, for some scattering polarization channels the presence of a control field can cause destructive interference through which the enhancement factor, normally considered to be greater than one, becomes less than one.
