description: We have studied Zn(CN)2 at high pressure using Raman spectroscopy, and report Gruneisen parameters of the soft phonons. The phonon frequencies and eigen vectors obtained from ab-initio calculations are used for the assignment of the observed phonon spectra. Out of the eleven zone-centre optical modes, six modes exhibit negative Gruneisen parameter. The calculations suggest that the soft phonons correspond to the librational and translational modes of CN rigid unit, with librational modes contributing more to thermal expansion. A rapid disordering of the lattice is found above 1.6 GPa from X-ray diffraction.

description: We describe a simple and fast technique to perform ultrasound differential phase contrast (DPC) imaging in arbitrarily thick scattering media. Though configured in a reflection geometry, DPC is based on transmission imaging and is a direct analogue of optical differential interference contrast (DIC). DPC exploits the memory effect and works in combination with standard pulse-echo imaging, with no additional hardware or data requirements, enabling complementary phase contrast (in the transverse direction) without any need for intensive numerical computation. We experimentally demonstrate the principle of DPC using tissue phantoms with calibrated speed-of-sound inclusions.

Temperature and stress are two influence factors of the magnetic properties of silicon steel, which means they affect the performance of electrical devices that use silicon steel sheets as cores. Accurate measurement and simulation of magnetic properties such as hysteresis and loss of magnetic materials under multiple working conditions are essential to their application in the design and improvement of new electromagnetic equipment. There are few devices that could measure the rotational magnetic properties under simultaneous loading of temperature and stress at present [1]. In order to obtain the magnetic properties of silicon steel sheets under a specific working condition, a 2-D magnetic measuring system that could apply temperature and stress at the same time is developed in this paper. The silicon steel sample is cut into a cross shape to fit the excitation structure consists of two orthogonal double-C yokes. An aluminum alloy plate with heating wires is used to locally heat the middle area of the sample. The uniformity and gradient changes of temperature loading were analyzed through simulation and experiment. Two stepper electrical cylinders are connected to the legs of the sample through stabilizers to apply stress. The magnetic flux density B and magnetic field intensity H in the middle area of the sample are measured by a combined B-H sensor which is able to withstand high temperatures above 200°C. The magnetic properties under different temperature and under different uniaxial stress of non-oriented silicon steels B25AV1300 are measured, which is under alternating magnetization. The hysteresis loop of magnetization along the rolling direction at different temperatures at a frequency of 400Hz and a magnetic flux density of 1T is shown in Fig. 1. Fig. 2 shows the power loss when different tensile and compress stress are applied along the rolling direction at different temperatures， at a frequency of 200Hz and a magnetic flux density of 1T. Results of rotational magnetic measurement will be presented in the full manuscript.References: [1] D. Zhang, K. Shi, Z. Ren, et al.

description: We investigate the isospin-violating mixing of the light scalar mesons a0(980) and f0(980) within the unitarized chiral approach. Isospin-violating effects are considered to leading order in the quark mass differences and electromagnetism. In this approach both mesons are generated through meson-meson dynamics. Our results provide a description of the mixing phenomenon within a framework consistent with chiral symmetry and unitarity, where these resonances are not predominantly q q-bar states. Amongst the possible experimental signals, we discuss observable consequences for the reaction J/Psi -> phi pi0 eta in detail. In particular we demonstrate that the effect of a0-f0 mixing is by far the most important isospin-breaking effect in the resonance region and can indeed be extracted from experiment.

description: Classical effective potentials are indispensable for any large-scale atomistic simulations, and the relevance of simulation results crucially depends on the quality of the potentials used. For complex alloys like quasicrystals, however, realistic effective potentials are practically inexistent. We report here on our efforts to develop effective potentials especially for quasicrystalline alloy systems. We use the so-called force matching method, in which the potential parameters are adapted so as to optimally reproduce the forces and energies in a set of suitably chosen reference configurations. These reference data are calculated with ab-initio methods. As a first application, EAM potentials for decagonal Al-Ni-Co, icosahedral Ca-Cd, and both icosahedral and decagonal Mg-Zn quasicrystals have been constructed. The influence of the potential range and degree of specialisation on the accuracy and other properties is discussed and compared.

description: Despite the superior performance in modeling complex patterns to address challenging problems, the black-box nature of Deep Learning (DL) methods impose limitations to their application in real-world critical domains. The lack of a smooth manner for enabling human reasoning about the black-box decisions hinder any preventive action to unexpected events, in which may lead to catastrophic consequences. To tackle the unclearness from black-box models, interpretability became a fundamental requirement in DL-based systems, leveraging trust and knowledge by providing ways to understand the model's behavior. Although a current hot topic, further advances are still needed to overcome the existing limitations of the current interpretability methods in unsupervised DL-based models for Anomaly Detection (AD). Autoencoders (AE) are the core of unsupervised DL-based for AD applications, achieving best-in-class performance. However, due to their hybrid aspect to obtain the results (by requiring additional calculations out of network), only agnostic interpretable methods can be applied to AE-based AD. These agnostic methods are computationally expensive to process a large number of parameters. In this paper we present the RXP (Residual eXPlainer), a new interpretability method to deal with the limitations for AE-based AD in large-scale systems. It stands out for its implementation simplicity, low computational cost and deterministic behavior, in which explanations are obtained through the deviation analysis of reconstructed input features. In an experiment using data from a real heavy-haul railway line, the proposed method achieved superior performance compared to SHAP, demonstrating its potential to support decision making in large scale critical systems.

Shielding, Levitation and Propulsion
Recently, permanent magnet synchronous motors to which PWM (Pulse Width Modulation) control is applied are mainly used. PWM control is a technique that can modulate not only the frequency of the output voltage but also the magnitude, and is a control method that generates pulses for turning on and off each phase switch. In addition, it is a technology that uses switching to control analog circuits with digital output, which is effective for motor control. In general, when designing a motor using FEM, a sinusoidal current waveform is used. When the motor is driven through PWM control, current contains harmonic components compared to sinusoidal current, and these harmonic components have a great influence on eddy current loss generated in permanent magnets. When designing a motor, it is possible to obtain more accurate analysis results by using a current waveform considering PWM control instead of using a conventional sinusoidal waveform. In this paper, the eddy current loss of the permanent magnet, which has a great effect on the performance of the motor, is compared using the division of the permanent magnet, and the eddy current loss of the permanent magnet is derived and compared using the sinusoidal current waveform and the current waveform considering PWM control. In a synchronous motor, since the rotating speed of the rotor and the speed of the stator rotating magnetic field are the same, eddy current loss for the fundamental wave does not occur. However, when harmonics exist, eddy current loss of permanent magnets occurs due to harmonics. Due to the harmonic components of the PWM current, the Total Harmonic Distortion(THD) of the line-to-line voltage under load increased by about 167% compared to the simulation result through the sinusoidal current waveform in comparison to the existing sinusoidal current waveform, and the torque ripple also increased by about 33%. When the magnet was not divided, the model using a sinusoidal current waveform measured 5.79W, and the model using a current waveform considering PWM measured 7.26W. When the magnet was divided, the model using a sinusoidal current waveform measured 0.416W and PWM The model using the considered current waveform measured 0.604W.

description: In this paper we report on the early evolution of core-collapse supernova explosion following the birth of a magnetar with the dipolar magnetic field of B=10^{15}G and the rotational period of 2ms, which was studied by means of axisymmetric general relativistic MHD simulations. The numerical models exhibit highly collimated magnetically-driven jets very early on. The jets are super-Alfvenic but remain sub-fast until the end of the simulations (t=0.2s). The power released in the jets is about 3x10^{50}erg/s which implies the spin-down time of ~37s. The total rotational energy of the magnetar, E~10^{52}erg, is sufficient to drive hypernova but it is not clear as to how large a fraction of this energy can be transfered to the stellar envelope. Given the observed propagation speed of the jets, v_p~0.17c, they are expected to traverse the progenitor in few seconds and after this most of the released rotational energy would be simply carried away by these jets into the surrounding space. Our results provide the first more or less self-consistent numerical model of a central engine capable of producing, in the supernova setting and on a long-term basis, collimated jets with sufficient power to explain long duration GRBs and their afterglows. Although the flow speed of our jets is relatively low, v_j~0.5c$, the cooling of proto-neutron star will eventually result in much higher magnetization of its magnetospheres and ultra-relativistic asymptotic speeds of the jets. Given the relatively long cooling time-scale we still expect the jets to be only weakly relativistic by the time of break out. This leads to a model of GRB jets with systematic longitudinal variation of Lorentz factor which may have specific observational signatures both in the prompt and the afterglow emission.

description: Multi-Label Image Classification (MLIC) aims to predict a set of labels that present in an image. The key to deal with such problem is to mine the associations between image contents and labels, and further obtain the correct assignments between images and their labels. In this paper, we treat each image as a bag of instances, and reformulate the task of MLIC as an instance-label matching selection problem. To model such problem, we propose a novel deep learning framework named Graph Matching based Multi-Label Image Classification (GM-MLIC), where Graph Matching (GM) scheme is introduced owing to its excellent capability of excavating the instance and label relationship. Specifically, we first construct an instance spatial graph and a label semantic graph respectively, and then incorporate them into a constructed assignment graph by connecting each instance to all labels. Subsequently, the graph network block is adopted to aggregate and update all nodes and edges state on the assignment graph to form structured representations for each instance and label. Our network finally derives a prediction score for each instance-label correspondence and optimizes such correspondence with a weighted cross-entropy loss. Extensive experiments conducted on various image datasets demonstrate the superiority of our proposed method.

Spin Orbitronics I
Thin films with perpendicular magnetic anisotropy (PMA) attained huge attraction among the spintronics researchers due to their application on high density data storage devices [1,2]. The HM converts the longitudinal charge current (Jx) into a transverse spin (Js) current due to the spin hall effect. The spin current gives spin-orbit torque (SOT) to the FM magnetization. The strength of SOT largely depends on effective the spin hall angle (θsh) of the HM. Therefore, tuning effective spin hall angle is very important to achieve current induced magnetization reversal (CIMR) at very low current density. Several HMs has been studied to quantify the θsh [3-5]. In this work, we prepared Ta/Pt/Co/Pt and Ta/Pt/Co/Au PMA multilayers and introduced Au layer at both sides of Co layer to prepare Ta/Pt/Co/Au/Pt, Ta/Pt/Au/Co/Pt and Ta/Pt/Au/Pt/Au multilayers (Fig. 1) and studied critical current density (Jc) required for magnetization reversal. The detailed measurement scheme can be found here [6]. The Jc with respect to in plane magnetic field (Hx) has been displayed in Fig. 2. The Jc decreases with increase in Hx for all the samples. The bottom and top Pt layers in S1 generate competing spin polarized current that minimizes SOT strength acting on magnetization of Co and as a result Jc = 3.13 × 1011 A/m2 obtained for switching is maximum at Hx = 100 mT among all samples. Introduction of Au layer between top Co/Pt interface (sample S2) the Jc drops only 5% at same Hx. In sample S3, the Au layer is introduced between bottom Pt/Co interface the current density drops significantly (∼50 %). In sample S4, Au layer generates negligible spin current and the bottom Pt layer acts as primary source of spin polarized current. In S4, the obtained Jc was not reduced significantly in. comparison with S1. The introduction of Au layer at bottom Pt/Co interface in S5 leads to reduction of Jc ∼49% with respect to S1. The lowering of Jc can be due to the reduction of spin memory loss or spin back flow at the Pt/Co interfaces of S3 and S5. Introduction of a thin layer of Au between bottom Pt/Co can significantly increase the the SOT strength and lower the Jc.References: 1. Parkin et. al., Science, 320, 190–194 (2008) 2.

The role of environmental colour
Creators: name: Avakumovic, Fiona
Publisher: name: University of British Columbia
Year: 2010

description: This thesis reviews the role of environmental colour, that found on the large manmade surfaces of pavements, facades and roofs. In addition, it provides a conceptual framework for the planner 'to think through' urban colour, that is, to reflect fully upon as a basis for developing strategies and evaluating options. In the built environment, colour is an essential, ubiquitous, enjoyable, and, now, highly topical element. However, much of the available information is, to the planner, too specialized, complicated by unresolved debates or dated. Therefore, to clarify the subject concisely and creatively for the planner, this thesis reviews pertinent literature, with material mainly drawn from architecture, fine arts, geography, optics, psychology, and urban design. Examples of recent or renowned uses of environmental colour, primarily from the 'Western' world for reasons of similarity of culture and climate to Canada, supplement the literature review. As a result, this thesis reveals to the planner that environmental colour may be thought through in terms of 'Place' and 'Power' and that, far from playing one principal role, environmental colour has many precise parts. Each of the surfaces on which colour occurs offers different constraints and opportunities for colour use. At various scales of perception, different factors also influence such use. Colour's power is both spatial, to transform the appearance of our surroundings through changing light conditions, surface spectral qualities, angles of perception, and synaesthesia, and psychological, to influence our well-being, through arousal, pleasure, and control. With this 'Power in Place', colour's symbolic, aesthetic, and functional values modify its six main roles, Background, Meaningful, Timely, Ciruculatory, Illusory, and Pictorial, to produce the array of precise parts which range from 'Backdrop' to 'Advertizer'. To realize the importance of these parts, the planner promotes 'thought through' environmental colour through strategies of education, exemplification, encouragement and enforcement, and through the contributions of various professional roles. However, more research is still needed about colour's environmental potential and the public's preferences in order to develop clear colour policies, especially if, as Ellen Marx (1972) confidently predicts: La tâche de l'urbaniste futur sera sans doute d'approfondir les critères qualitatifs et quantitatifs de la couleur et de la lumière, en collaboration étroite avec des biologistes, des psychologues, et des socilogues qui auront défini les besoins fondamentaux de silence, de l'espace, d'information et de communication de l'être humain. (The task of the future urban planner will undoubtably be to deepen the qualitative and quantitative criteria of colour and light, in direct collaboration with biologists, psychologists, and sociologists who will have defined the fundamentals of silence, space, information, and communication needed to be human.)

Thin Films, Multilayers and Interface Effects II
Magnetic nanoparticles (MNPs) have been the subject of intense study for many decades, due, in part, to their many applications such as water/gas purification to data storage to drug delivery. While it is well-known that the physical properties of MNPs, such as composition, size and size distribution, crystallinity, shape, etc. determine the magnetic properties, it is not as widely discussed what impact the MNP environment has on the measured properties. For example, MNPs can physically move in a liquid under the influence of an external magnetic field, forming structures like rings and chains [1]. When dispersed in a solid matrix, or nanocomposites, their physical movement can be significantly restricted, if not eliminated, leaving only magnetic (Neel) rotations. Here, we compared colloidal dispersions of iron oxide MNPs in water and toluene with nanocomposites of the iron oxide MNPs made by dispersion of the MNPs in polymer followed by either UV polymerization (water-based) or rapid precipitation (toluene-based). Measurement of magnetization as a function of applied field show two distinct behaviors: the nanocomposite virgin curve is centered in the first quadrant major loop before merging with the falling major loop, in stark contrast with the MNPs in liquid which track the rising side of the major loop (Fig. 1). Furthermore, in the nanocomposites, there is a peak in the imaginary AC susceptibility component based on the magnetic properties of the individual MNPs. In liquid, the peak in the imaginary component shifts out of range based on the magnetic properties of a chain. (Fig. 2) The changing structures possible in liquid (which are restricted in nanocomposites) also modify the interactions, resulting in a dynamic magnetic anisotropy [2]. This has profound implications for magnetic applications, especially as many of these use AC magnetic fields where the magnetic anisotropy is crucial to their detailed response.References: 1.

description: User electromagnetic (EM) exposure is continuously being exacerbated by the evolution of multi-antenna portable devices. To mitigate the effects of EM radiation, portable devices must satisfy tight regulations on user exposure level, generally measured by specific absorption rate (SAR). To this end, we investigate the SAR-aware uplink precoder design for the energy efficiency (EE) maximization in multiuser multiple-input multiple-output transmission exploiting statistical channel state information (CSI). As the objective function of the design problem is computationally demanding in the absence of closed form, we present an asymptotic approximation of the objective to facilitate the precoder design. An iterative algorithm based on Dinkelbach's method and sequential optimization is proposed to obtain an optimal solution of the asymptotic EE optimization problem. Based on the transformed problem, an iterative SAR-aware water-filing scheme is further conceived for the EE optimization precoding design with statistical CSI. Numerical results illustrate substantial performance improvements provided by our proposed SAR-aware energy-efficient transmission scheme over the traditional baseline schemes.

description: We studied the non-equilibrium dynamics of the q-state Potts model in the square lattice, after a quench to sub-critical temperatures. By means of a continuous time Monte Carlo algorithm (non-conserved order parameter dynamics) we analyzed the long term behavior of the energy and relaxation time for a wide range of quench temperatures and system sizes. For q>4 we found the existence of different dynamical regimes, according to quench temperature range. At low (but finite) temperatures and very long times the Lifshitz-Allen-Cahn domain growth behavior is interrupted with finite probability when the system stuck in highly symmetric non-equilibrium metastable states, which induce activation in the domain growth, in agreement with early predictions of Lifshitz [JETP 42, 1354 (1962)]. Moreover, if the temperature is very low, the system always gets stuck at short times in a highly disordered metastable states with finite life time, which have been recently identified as glassy states. The finite size scaling properties of the different relaxation times involved, as well as their temperature dependency are analyzed in detail.

Then we proceed with a construction of an operational calculus of the Mikusiński type for the general fractional derivatives with the Sonine kernels. This operational calculus is applied for analytical treatment of some initial value problems for the fractional differential equations with the general fractional derivatives. The solutions are expressed in form of the convolution series that generalize the power series for the exponential and the Mittag-Leffler functions.

Biomedical Applications I
When an inflammatory response occurs in the body, primary immune cells, such as macrophages, phagocytize and present antigens, and secondary immune cells, such as T cells, produce antibodies against the presented antigens to prevent infection in the body.[1] Excessive inflammation releases pro-inflammatory cytokines such as TNF-α and IL-6, which damage normal tissues and cells in the body, leading to rheumatoid arthritis and sepsis.[2] This study has tried to confirm the change in inflammatory activity across innate immunity and acquired immunity and investigate the effects of pulsed magnetic field (PMF) on the immune system in regulating excessive inflammation. Raw 264.7 and EL4 cells were co-cultured in a DMEM medium using insert well. Inflammation was induced using LPS. Our PMF stimulator has the maximum intensity of 4700G at a transition time of 136 μs with pulse intervals of 1Hz. In order to confirm changes in inflammatory activity between the two cells and the anti-inflammatory effects of PMF, the level of IL-6 and mitochondrial activity (MA) were measured using ELISA and MTT assay, respectively. The concentration of IL-6 increased in macrophages and T cells after inflammation was induced, and decreased after PMF stimulation. MA also increased under inflammation. When PMF was applied after inflammation induction, MA decreased in both cells, suggesting that PMF has an anti-inflammatory effect on the immune system. From the results of both experiments, it was confirmed that macrophages respond more rapidly than T cells to PMF stimulation with a decrease in cellular activity and a decrease in IL-6, which indicates inflammation relief. Our results show that macrophages, the primary immune cells, are first involved in the inflammatory response and recovery and influence T cells, the secondary immune cells. Therefore PMF stimulus is thought to affect the immune system of the human body by balancing the activation and suppression of immune cells and improve anti-inflammation. For clinical use, non-invasive PMF can be developed as a medical devices modulating immune system with optimizing the PMF conditions such as pulse shape, duration, or repetition rate.References: [1] M.

Novel solid-liquid phase separation diffused (SepD) Nd-Fe-B sintered magnets were successfully prepared by using TbH3 nanopowder [1]. In this study, SepD and solid-liquid phase simultaneous diffusion (SimD) are used to create grain boundary diffusion (GBD) Nd-Fe-B sintered magnets by using DyH3 nanopowder. The magnetic properties and microstructure of sintered Nd-Fe-B magnets of varying thicknesses are thoroughly investigated. The magnetic properties of SepD magnets are higher than SimD magnets when the weight increase ratio is 0.25 wt.% as shown in Fig. 1. When the magnet is 8 mm thick, SepD magnets have a coercivity of 18.10 kOe, which is higher than SimD magnets (17.00 kOe). It is determined that this new GBD mode can manufacture thick magnets with excellent coercivity. The diffusion depth of the Dy element in SepD magnets is deeper than that in SimD magnets. The core-shell structure is formed on the surface of the SepD magnet with a wider shell, while there forms an anti-core-shell structure that is unfavorable to magnetic properties on the surface of the SimD magnet as shown in Fig. 2. More continuous core-shell structure created by the deeper diffusion depth of the Dy element is the fundamental cause of the enhanced coercivity of the SepD magnet.References: [1] Z. J. Wang, M.

Permanent magnet (PM) motors have been widely applied, due to high torque density and operating efficiency. However, since PM motors air gap magnetic field is difficult to adjust, its speed regulation range of constant power is relatively narrow. In recent years, variable leakage flux PM (VLF-PM) motor has been proposed [1]. By the targeted design of the magnetic barrier, bypass leakage flux can be controlled, so air-gap flux can be adjusted and corresponding motor speed range can be expanded. However, the magnetic leakage in the motor often leads to the reduction of torque output capability. Therefore, how to improve the torque output capability of the motor while ensuring its wide speed regulation capability has become a difficult research topic in the field of VLF-PM motors. To address this issue, this paper introduces a U-shaped variable leakage flux hybrid PM (VLF-HPM) motor. By incorporating ferrite magnets, the motor achieves the superposition of magnetic potential from the magnetic sources. Moreover, the ferrite magnets mitigates the end magnetic leakage of the NdFeB magnets, thereby improving the utilization rate of NdFeB magnets under heavy load conditions. Consequently, the increased torque output capacity and expanded speed range of VLF-HPM motor can be realized simultaneously. Fig. 1 shows the proposed VLF-PM and VLF-HPM motors and their flux leakage paths. Fig. 2(a) and Fig. 2(b) present the magnetic field lines and magnetic density distributions of the two motors under rated working condition. Fig. 2(c) shows that VLF-HPM motor not only improves the PM flux linkage compared to the VLF-PM motor, but also increases the magnetic adjustment range from 24.5% to 35.5%. The total torque is also increased by 2Nm, as shown in Fig. 2(d). Due to the introduction of ferrite materials, the reluctance torque of VLF-HPM motor is increased by 5.5Nm in Fig. 2(e). Table 1 shows the cost and basic performance of the motor[2]. Fig. 2(f) shows the curves of torque-speed and power-speed of the two motors. In conclusion, the proposed VLF-HPM motor can not only realize the torque output capacity, but also expand the speed regulation range. More simulation and experimental results will be presented in the full paper.References: [1] L.

description: A new simple qubit model of black hole evaporation is proposed. The model operates on four qubits and is defined in terms of quantum gates and a quantum circuit. The chief features of the model include explicit unitarity and (most notably) causality which is understood as the impossibility of the transfer of information from the interior of the black hole through its horizon. The corresponding von Neumann entanglement entropy yields a crude (four-qubit) approximation of the Page curve.

The effectiveness of employing La-Ca-Co co-doing has been demonstrated as the optimal approach for enhancing the magnetic performance of strontium ferrite [1-2]. However, limited studies have explored the evolution of the magnetoplumbite phase and its correlation with the two-step sintering temperature for La-Ca-Co doped strontium ferrite (LCCSFO). In our research, we show the progression of the M-phase and determine the ideal temperature for attaining the maximum magnetic performance of LCCSFO. LCCSFO permanent magnets were fabricated using a conventional ceramic process and a two-step sintering technique. In the initial phase, the powder, which was wet mixed and pelletized, underwent calcination at 1260 oC followed by a second step of sintering at varying temperatures between 1175 oC and 1205 oC. XRD results in Fig.1 (a) validated the presence of the hexagonal (P63/mmc) SrFe12O19 phase in the doped samples. After sintering at different temperatures, all the samples possess proper c-axis orientation, as shown in Fig.1 (b). When the sintering temperature was raised from 1175 °C to 1205 °C, there was an upward trend observed in the remanence Br, as shown in Fig.2 (a), increasing from 0.430 T to 0.439 T. The coercivity Hcj exhibited an increase from 380 kA/m and reached its peak at 397 kA/m at 1185 °C. Although the Br value remained favorable, the coercivity experienced substantial deterioration, reaching its lowest point at 303 kA/m at 1205 °C. Under ideal circumstances, the optimal magnetic performance was achieved, with Br measuring 0.439 T, Hcj at 379 kA/m, Hcb at 318 kA/m, and (BH)max at 35.5 kJm-3 at a sintering temperature of 1195 oC.
