Racial Capitalism and Black Maternal Mortality Rates in Chicago
Creators: name: Bovat, Sara
Publisher: name: Unknown
Year: 2021

description: Non-Hispanic, Black women in the United States experience the highest maternal morbidity and pregnancy-associated mortality rates. These rates hold for Chicago as well. On April 12, 2021, Illinois became the first state to expand Medicaid coverage from 60 days postpartum to 12 months postpartum when its Illinois Continuity of Care & Administrative Simplification 1115 Waiver was approved by the Centers for Medicare and Medicaid Services. The waiver should lower the number of Black women dying from pregnancy-associated causes. However, the policy only addresses the issues of access related to the social determinants of health, and not the heavily embedded biases rooted in anti-Black, structural racism. This paper uses the idea of racial capitalism to examine Chicago’s high rates of Black morbidity and mortality rates surrounding pregnancy and the potential limitations of the state’s expansion of Medicaid coverage for postpartum care.

description:
Phengite is the main nitrogen (N) carrier in high-P/T metamorphosed rocks in subduction zones (e.g. Halama et al., 2017; Abdel-Hak et al., 2020). N is incorporated as ammonium (NH4+) substituting for K+. The significant amounts of NH4+ observed in natural phengite from the high-P metasediments of the Dora Maira Massif (Busigny et al., 2003) suggest that N can be retained during subduction and recycled into the deep mantle. Understanding the pathways of N during subduction, however, requires an understanding of the partitioning behavior of N within the hosting phases (Mikhail et al., 2017). Accordingly, we studied the exchange of NH4+ between phengite and fluid experimentally.

Piston-cylinder experiments using the ‘’synthesis exchange technique’’ (Zimmermann et al., 1997) were performed at 700°C, 4.0 GPa for the synthesis of K-NH4-phengites solid solutions. Starting materials were solid oxide mixtures and chloridic solutions.

After the experiments, solid run products were examined by X-ray powder diffraction with Rietveld analysis, and infrared spectroscopy. Cations in the product fluids were analyzed by ion chromatography.

Resulting coefficients (KD) for the K- NH4 exchange range from 0.77±0.13 to 1.42±0.18. Results show that at these P-T conditions, NH4+ partitions equally between phengite and coexisting fluid. Pöter et al. (2004) performed partitioning experiments between tobelite (an NH4+-muscovite mineral) and fluid at lower pressures (0.4 & 1.5 GPa). Here, contrary to our results, NH4+ shows preferential partitioning into the fluid phase. This pressure-induced change in the partitioning behavior highlights the significance of high pressures in increasing the extent to which N can be recycled during subduction.

description: Accretion models predict two ejections along the eccentric orbit of LS I +61 303: one major ejection at periastron and a second, lower ejection towards apastron. We develop a physical model for LS I +61 303 in which relativistic electrons are ejected twice along the orbit. The ejecta form a conical jet that is precessing with P2. The jet radiates in the radio band by the synchrotron process and the jet radiates in the GeV energy band by the external inverse Compton and synchrotron self-Compton processes. We compare the output fluxes of our physical model with two available large archives: OVRO radio and Fermi Large Area Telescope (LAT) GeV observations, the two databases overlapping for five years. The larger ejection around periastron passage results in a slower jet, and severe inverse Compton losses result in the jet also being short. While large gamma-ray emission is produced, there is only negligible radio emission. Our results are that the periastron jet has a length of 3.0 10^6 rs and a velocity beta ~ 0.006, whereas the jet at apastron has a length of 6.3 10^7 rs and beta ~ 0.5.

Analysis of Effect of Train Overload on Disc Brake of AALRT
Creators: name: Solomon, Kebebew
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Changes in the train dynamics characteristics such as train weight will affect the train's braking performance and its ability to stop safely in braking situation. This paper studies about the disc temperature and von misses stress of train over loading used in AALRT. A transient thermal analysis has been carried out to investigate the temperature variation across the disc using ANSYS 14.5. Further structural analysis is also carried out by coupling with thermal analysis. A more realistic braking disc model for AALRT under various over load percentages, road grade level and maximum travel speed of 70km/h is analyzed. The model of disc brake is done by CATIA software and then simulation was followed using ANSYS 14.5 workbench. Results from this research showed that the temperature and stress on disc brake during service brake at downhill train position and unacceptable load condition has increased by 37.08 o c and 56 Mpa from acceptable load and the same train position. When a repetitive braking is applied the temperature and von misses stress during train overload has increased by 37.07 o c and 56 Mpa respectively. Similarly, when the emergency brake is applied during normal and unacceptable load condition, the temperature and stress on the disc has increased by 41.4 o c and 51 Mpa in time of downhill track position. In general, overloading the train has the effect of increasing the temperature and stress induced in to the disc brake rotor during braking

description: We investigate the open dynamics of a quantum system when it is rapidly repeatedly updated by a quantum channel. Specifically, we analyze when this dynamics can purify the system. We develop a necessary and sufficient condition for such purification effects to occur and characterize their strength. We thoroughly analyze the specific scenario of a quantum system undergoing rapid unitary interactions with a sequence of ancillary quantum systems. We find that while the purification effects are generally present, in order for these effects to be strong compared to the decoherence effects the interaction Hamiltonian must have a minimum degree of complexity. Specifically, a tensor product interaction $\hat{Q}_\text{S}\otimes\hat{R}_\text{A}$, as well as many common light-matter interactions cannot purify efficiently.

Simulation of Crack Propagation of a Skidded Rail Wheel Using Extended Finite Element Method (XFEM)
Creators: name: Natnael, Mandefro
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: In this thesis work, an investigation of a crack growth pattern due to the additional effect of the frictional heat induced on the static mechanical full load due to skidding of a wheel on a rail is conducted using an Extended Finite Element Method (XFEM). The contact parameters are determined using Hertz contact theory. The assumption of the elliptical contact pressure distribution is linearized to give a simple rectangular pressure distribution. The contact elliptical area is also assumed to be as an equivalent rectangular area. The frictional heating case is considered at the maximum sliding velocity having in mind the full loading spectrum of the wheel on the entire journey. The Material of the wheel is assumed to be an isotropic hardened Elastic-plastic material and the damage initiation criterion selected is the maximum principal stress. An energy based damage evolution is selected for the crack growth simulation. The crack Extension pattern with respect to the crack tip maximum principal stress and Equivalent plastic strain (PEEQ) are plotted for both case scenarios and it is can then be inferred that the as the crack length increases the crack tip stress and plastic strain also increases therefore the wheel will lose integrity for further successive damage.
Reduced Order Podolsky Model

description: We perform the canonical and path integral quantizations of a lower-order derivatives model describing Podolsky's generalized electrodynamics. The physical content of the model shows an auxiliary massive vector field coupled to the usual electromagnetic field. The equivalence with Podolsky's original model is studied at classical and quantum levels. Concerning the dynamical time evolution we obtain a theory with two first-class and two second-class constraints in phase space. We calculate explicitly the corresponding Dirac brackets involving both vector fields. We use the Senjanovic procedure to implement the second-class constraints and the Batalin-Fradkin-Vilkovisky path integral quantization scheme to deal with the symmetries generated by the first-class constraints. The physical interpretation of the results turns out to be simpler due to the reduced derivatives order permeating the equations of motion, Dirac brackets and effective action.

description: Prions are infectious protein particles known to cause prion diseases. The biochemical entity of the pathogen is the misfolded prion protein (PrPSc) that forms insoluble amyloids to impair brain function. PrPSc interacts with the non-pathogenic, cellular prion protein (PrPC) and facilitates conversion into a nascent misfolded isoform. Several small molecules have been reported to inhibit the aggregation of PrPSc but no pharmacological intervention was well established thus far. We, here, report that acylthiosemicarbazides inhibit the prion aggregation. Compounds 7x and 7y showed almost perfect inhibition (EC50 = 5 µM) in prion aggregation formation assay. The activity was further confirmed by atomic force microscopy, semi-denaturing detergent agarose gel electrophoresis and real-time quaking induced conversion assay (EC50 = 0.9 and 2.8 µM, respectively). These compounds also disaggregated pre-existing aggregates in vitro and one of them decreased the level of PrPSc in cultured cells with permanent prion infection, suggesting their potential as a treatment platform. In conclusion, hydroxy-2-naphthoylthiosemicarbazides can be an excellent scaffold for the discovery of anti-prion therapeutics.
Comparative Study on Biogas Production Potential of Sewage, Slaughterhouse, Fruit-Vegetable Wastes and their Co-digestion

description: Currently, 1.5 liters per person per day (De Mes and Stams, 2003) faeces and urine as sewage waste, 45 to 60m3/day SHW and 2 to 3 trucks/day of FVW generated in Addis Ababa. The main objective of this work was to make comparative study on the biogas generation potential of SW, SHW, FVW, and their co-digestion (M) by using wet batch anaerobic digestion technology. Specifically the study investigated how the performance of anaerobic digestion is affected by temperature, retention time, and waste types. The temperature levels used were room temperature, 37°C and 45°C. Wet mesophilic anaerobic digestions of SW, SHW, FVW and co-digestion of their mixture have been investigated. Wastes samples were characterized in terms of TS, VS, pH, BOD5, COD, total nitrogen and C: N ratio as per the existing standards. Biogas produced was characterized using biogas analyzer. The data from the experiment was analyzed and modeled using Design-Expert version 6.0.8 and significance was accepted at 0.05 level of probability (p<0.05). Comparatively, maximum of 63.9, 77.8, 70.0 %CH4 biogas was observed for co-digestion of aforementioned wastes at room, 37°C and 45°C, respectively. This study shows that %CH4 in the biogas increases with retention time until it reaches optimum point and decrease afterwards. It also shows that biogas production increases in the temperature range investigated irrespective of waste types. Maximum methane yields of 0.12 and 0.16 liters per gram volatile solids digestion (lCH4/gVS) was achieved at 37°C from SHW and M, respectively. Similarly, maximum methane yields of 0.09 and 0.13 lCH4/gVS was achieved at 45°C from FVW and SWs, respectively. Keywords: Sewage waste, Co-digestion, Fruit-Vegetable waste, Methane yield

description: ABSTRACT
 Caring is the fundamental core component in the nursing profession and nurse-patient interaction. Competency is the integration of skills, values, knowledge, and attitudes to specific, contextual practice situations.
 In the Middle East, particularly in Qatar, the health care sector depends greatly on expatriates. The link between nurse competency and caring efficacy has not been directly investigated thoroughly in a different clinical setting. Professional nursing practice is the vital role of nurses towards patient-centered care, teamwork, and collaboration, evidence-based practice, quality improvement, safety, and informatics.
 Professional caring behaviors include developing good relationships with
 patients and other staff; working in a self-directed manner; making clinical
 decisions and the management of practice. This descriptive correlational
 research design aims to examine the relationship between nurse competency
 and caring efficacy among primary health care nurses.
 A total of 102 nurses of the medical services department from different health
 care facilities of the Ministry of Interior, Doha, Qatar were included in the final
 sample using purposive sampling. The average age of nurses was 37 years old, most were Filipino nurses, married and had a baccalaureate degree. The
 average of the length of nursing experience was 3 years and the mean average of the length of the nursing service was 2 years. Data were collected using Nurse Quality and Safety Inventory scale and Caring Efficacy Scale. The study showed that there was a significant relationship between nurse
 competency and caring efficacy. Specifically, nurse competency had a
 significant, positive, and direct but weak relationship to caring efficacy. Furthermore, this suggests that nurse competency increases with increasing
 caring efficacy. Nurse competency is a vital element in the provision of nursing care. It is a synthesis of skills, knowledge, attitudes, values, and abilities in providing safe, effective, and quality care to individuals, families, and communities. Thus, having professional nurse competency leads to professional caring behavior that directly affects safe and quality health care delivery. It also increases patient satisfaction, helps promote nursing as a profession, and improves nursing education and clinical nursing practice.

description: Research on Offline Handwritten Signature Verification explored a large variety of handcrafted feature extractors, ranging from graphology, texture descriptors to interest points. In spite of advancements in the last decades, performance of such systems is still far from optimal when we test the systems against skilled forgeries - signature forgeries that target a particular individual. In previous research, we proposed a formulation of the problem to learn features from data (signature images) in a Writer-Independent format, using Deep Convolutional Neural Networks (CNNs), seeking to improve performance on the task. In this research, we push further the performance of such method, exploring a range of architectures, and obtaining a large improvement in state-of-the-art performance on the GPDS dataset, the largest publicly available dataset on the task. In the GPDS-160 dataset, we obtained an Equal Error Rate of 2.74%, compared to 6.97% in the best result published in literature (that used a combination of multiple classifiers). We also present a visual analysis of the feature space learned by the model, and an analysis of the errors made by the classifier. Our analysis shows that the model is very effective in separating signatures that have a different global appearance, while being particularly vulnerable to forgeries that very closely resemble genuine signatures, even if their line quality is bad, which is the case of slowly-traced forgeries.

description: Supersymmetrical (SUSY) intertwining relations are generalized to the case of quantum Hamiltonians in Minkowski space. For intertwining operators (supercharges) of second order in derivatives the intertwined Hamiltonians correspond to completely integrable systems with the symmetry operators of fourth order in momenta. In terms of components, the itertwining relations correspond to the system of nonlinear differential equations which are solvable with the simplest - constant - ansatzes for the "metric" matrix in second order part of the supercharges. The corresponding potentials are built explicitly both for diagonalizable and nondiagonalizable form of "metric" matrices, and their properties are discussed.

description: Distributed Hash Tables (DHT) are a common architecture for decentralized applications and, therefore, would be suited for privacy-aware applications. However, currently existing DHTs allow every peer to access any index. To build privacy-aware applications, we need to control this access. In this paper, we present k-rAC, a privacy-aware fine-grained AC for DHTs. For authentication, we present three different mechanisms based on public-key cryptography, zero-knowledge-proofs, and cryptographic hashes. For authorization, we use distributed AC lists. The security of our approach is based on k-resilience. We show that our approach introduces an acceptable overhead and discuss its suitability for different scenarios.

description: Welsh Wreck Web Research Project unpublished report series, 1
description: The Active was a wooden Brig of 134 tons built by T & J Brocklebank in Whitehaven in 1800, who were the first owners. Active made voyages to Archangel, and other ports in Russia, Barbados, the Azores, British America and to Ireland, mainly Dublin. The Active travelled in a Naval convoy from Cork to Barbados to protect it from being captured in 1807. It was 1814 before Active was reported as being chased by a privateer in the English Channel for 4 hours before it escaped. Active was returning from Quebec in British America with timber when after calling at Waterford in Ireland she continued to her destination at Cardigan. Active then encountered a N W gale as she was at anchor waiting for the tide and was driven on shore on the Cardigan bar and wrecked. The captain and two boys were drowned but the remaining crew of 9 and the captains wife were rescued by boats from the shore. The captains wife had been lashed in mast top of Active and was cut free shortly before the masts fell overboard. The cargo was washed ashore, some of it in Aberystwyth.
Wheel Rail Interaction Modeling on Rail Vehicle System Lateral Dynamics

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: The long history of railway engineering provides many practical examples of dynamic problems which are unique to railway vehicles. One of the railway vehicle's dynamic problems is the lateral dynamic which is mainly arising from wheel rail contact condition. In the early time, to analyze and formulate such kinds of railway vehicle dynamics scientists had been using different experimental methods such as roller rigs and roller coasters. Even though such experimental methods are most efficient and error free, they are very costly and need some time. But now a day there are different computer packages used to study and simulate the dynamic behavior of a railway vehicle (ADAMS/RAIL, SIMPAKC and Vampire). These computational packages are very efficient in both cost and time but they are not more flexible and require indepth knowledge to run them. So this paper tried to make the computational tool more flexible and easy to use with basic computer knowledge In the work presented, mathematical model and computational tool used for the dynamic simulation of railway vehicle wheelset systems was developed using multibody systems formulations. The model based on the multibody techniques developed by Shabana. With respect to other exciting methodologies the proposed one make use of a combined frame of references that permit the use of independent coordinates, without the possibility to have singularity configurations depending on the rotation sequence. Lagrangian Equation of motions such as virtual work and kinetic and potential energy are used to develop the equation of motion. Finally a MATLAB program is developed to analyze the dynamic behavior of the wheelset at different velocities on a straight track. The program was designed to considering the flexibility of different configuration of railway vehicles. The model used was applied to make a simulation for single wheelset. The analysis were made for different velocities, lower than the critical in which the vehicle responded in stable form, and higher than the critical at which the instability of the vehicle was studied. The obtained results of the dynamic response for a defined track composed of tangent segment is analyzed and compared with one published paper.

description: Filaments in Herschel molecular cloud images are found to exhibit a "characteristic width". This finding is in tension with spatial power spectra of the data, which show no indication of this characteristic scale. We demonstrate that this discrepancy is a result of the methodology adopted for measuring filament widths. First, we perform the previously used analysis technique on artificial scale-free data, and obtain a peaked width distribution of filament-like structures. Next, we repeat the analysis on three Herschel maps and reproduce the narrow distribution of widths found in previous studies $-$ when considering the average width of each filament. However, the distribution of widths measured at all points along a filament spine is broader than the distribution of mean filament widths, indicating that the narrow spread (interpreted as a "characteristic" width) results from averaging. Furthermore, the width is found to vary significantly from one end of a filament to the other. Therefore, the previously identified peak at 0.1 pc cannot be understood as representing the typical width of filaments. We find an alternative explanation by modelling the observed width distribution as a truncated power-law distribution, sampled with uncertainties. The position of the peak is connected to the lower truncation scale and is likely set by the choice of parameters used in measuring filament widths. We conclude that a "characteristic" width of filaments is not supported by the available data.

description: Welsh Wreck Web Research Project unpublished report series, 1
description: The Advance was a ketch built at Pembroke Dock in 1893 by W & J Francis for W Francis. She traded mainly between Wales, Southern Ireland and the Channel Islands. The next owner of Advance was Mrs Annie Graham, the Master being W J Graham with W France remaining as manager. The Advance had a number of masters with Graham returning as master again before her sale in 1905. Advance was sold to two brothers from Braunston, Devon with Sidney Incledon being the master. On Advance's first voyage under the new owners she sprang a leak after leaving Milford on a voyage from Bideford to Glasgow carrying clay. The pumps were unable to stem the rising water and the crew abandoned her in the ship's boat and were picked up by the steamer Lestras and conveyed to Liverpool. Advance did not founder immediately and was reported floating derelict with the sea washing over her near Bardsey Island after being abandoned.

title: Lords, land and livelihood : a study into the estate management of the lesser lay tenants-in-chief in Kent before the Black Death, c.1246-1348
Creators: name: Everett, V

description: This thesis is a study of the estate economy of the lesser lay gentry in Kent c.1246- 1348, based on an analysis of data from 280 surveys relating to more than 160 estates augmented by detailed case studies. Over this period the demesne management on many great estates became increasingly market-oriented and it has also been argued that peasant involvement in buying and selling of produce grew, it being crucial to their survival. In this work it is argued that, in Kent, the lesser gentry were not so concerned with a market economy. The typical estate was contained within a radius of about five miles, with management policies which emphasised supplying the needs of the household. Where the gentry did use the market was in the purchase of land. Many lords were also able to increase their demesnes in this way. Case-studies are made of two successful families. The demesne was important on estates of all sizes, typically accounting for 40%-60% of the total value of a manor. On many estates, most of the demesne produce appears to have been sent to the household. Also important for the supply of provisions was the manorial garden and a survey is made of this resource. Analysis is made of the opportunities for income from woodland. It is found this was managed as a long term asset and rarely 'wasted'. A survey is made of the rent and court income to be made from tenants. This was restricted by the customary rights of the Kentish peasant. Labour services, for example, were light, particularly on manors of 'recent' origin. The costs of labour are analysed for demesnes of different sizes. Investment in the local community, in the form of mills and markets, is analysed. Many lords engaged successfully in the former but only the higher aristocracy could guarantee a return from the latter. Finally, a model of the smaller lay estate is proposed, with the conclusion that, in a majority of cases, the estate was managed primarily to feed the household. If the capacity for demesne production grew, so did household size, to reflect the enhanced status of the lord in the locality.

description: Elevated concentrations of fluoride in drinking water are a serious health concern. Dental and skeletal fluorosis being the most commonly reported fluoride-related diseases in Ethiopian rift valley. Various naturally occurring materials have been explored as adsorbents for the removal of fluoride from water .This study investigate the fluoride removal capacity of spent diatomaceous earth from aqueous solution. The spent diatomaceous earth was collected, washed and dried in an oven at 110 0C for 24 hrs. The dried 10 gram of spent diatomaceous earth was reacted in 100 ml of 0.1M HCl and dried in an oven at 110 0C .The dried spent diatomaceous are powdered, sieved and preserved. The effect of processing conditions (pH, initial fluoride concentration, adsorbent dose and contact time) was investigated using batch adsorption experiments. The adsorption efficiency was increased with increasing contact time and adsorbent dose and decreased with increasing pH and initial fluoride concentration. At low pH (2) maximum amount of fluoride was adsorbed by acid treated spent diatomaceous earth (58.48). Response surface methodology (RSM) involving Box–Behnken design was used to optimize the adsorption process of fluoride ions. The second order mathematical model was developed by regression analysis of the experimental data obtained from 29 batch runs. The optimum pH, initial fluoride concentration, adsorbent dose and contact time were found by desirability function to be 2.02,24.04mg/l, 18.83g and 2.95 hr respectively. Fluoride removal was 43.19% at the optimum combination of process parameters. The results of validation experiments conducted at optimum conditions for the removal of fluoride ions (42.94%) indicate that the predicted values are in good agreement with the experimental result. The adsorption data were well fitted to the Langmuir and Freundlich isotherm model. The adsorption capacity was 0.321 mg/g. Acid treated spent diatomaceous earth could be used as adsorbent for fluoride ion containing aqueous solution

description: Condensation of objects into stable clusters occurs naturally in equilibrium and driven systems. It is commonly held that potential interactions, depletion forces, or sensing are the only mechanisms which can create long-lived compact structures. Here we show that persistent motile structures can form spontaneously from hydrodynamic interactions alone with no sensing or potential interactions. We study this structure formation in a system of colloidal rollers suspended and translating above a floor, using both experiments and large-scale 3D simulations. In this system, clusters originate from a previously unreported fingering instability, where fingers pinch off from an unstable front to form autonomous "critters", whose size is selected by the height of the particles above the floor. These critters are a stable state of the system, move much faster than individual particles, and quickly respond to a changing drive. With speed and direction set by a rotating magnetic field, these active structures offer interesting possibilities for guided transport, flow generation, and mixing at the microscale.

description: Social work clinical literature describes methods for developing clinical relationships that embrace flexibility, authenticity, and efficacy. Translation, or the private use of one’s spirituality to inform engagement with clients, is an area of social work practice that can aid in fostering such relationships. The Four Noble Truths as described in Theravada Buddhism provide a model for the care of the self that practitioners can use to inform their practice. This paper explores these Buddhist principles in conjunction with the relevant social work literature so as to highlight the variables of effective clinical relationships.

description: Donor electron spins in semiconductors make exceptional quantum bits because of their long coherence times and compatibility with industrial fabrication techniques. Despite many advances in donor-based qubit technology, it remains difficult to selectively manipulate single donor electron spins. Here, we show that by replacing the prevailing semiconductor host material (silicon) with germanium, donor electron spin qubits can be electrically tuned by more than an ensemble linewidth, making them compatible with gate addressable quantum computing architectures. Using X-band pulsed electron spin resonance, we measured the Stark effect for donor electron spins in germanium. We resolved both spin-orbit and hyperfine Stark shifts and found that at 0.4 T, the spin-orbit Stark shift dominates. The spin-orbit Stark shift is highly anisotropic, depending on the electric field orientation relative to the crystal axes and external magnetic field. When the Stark shift is maximized, the spin-orbit Stark parameter is four orders of magnitude larger than in silicon. At select orientations a hyperfine Stark effect was also resolved and is an order of magnitude larger than in silicon. We report the Stark parameters for $^{75}$As and $^{31}$P donor electrons and compare them to the available theory. Our data reveal that $^{31}$P donors in germanium can be tuned by at least four times the ensemble linewidth making germanium an appealing new host material for spin qubits that offers major advantages over silicon.

description: The research aims reviewing currently available braking systems on different high speed trains which are found around the world and finally evaluates such systems using one of the Multicriteria decision making method TOPSIS. To do so various factors useful for evaluation were selected and utilized after examining different literatures. The result show that a significant importance of regenerative brake followed by rheostatic, eddy current E-P and magnetic track brakes. The result can help planners and engineers to conduct preliminary general assessments concerning the suitability of the five brake system, to develop tools for evaluation, to assess different brake system for a given high-speed train, and also helpful for anyone who engaged with train braking. The result obtained is satisfactory and currently 82.35% of high speed trains around the world use regenerative brake system.
Turbulence and Particle Acceleration in Giant Radio Haloes: the Origin of Seed Electrons

description: About 1/3 of X-ray-luminous clusters show smooth, Mpc-scale radio emission, known as giant radio haloes. One promising model for radio haloes is Fermi-II acceleration of seed relativistic electrons by compressible turbulence. The origin of these seed electrons has never been fully explored. Here, we integrate the Fokker-Planck equation of the cosmic ray (CR) electron and proton distributions when post-processing cosmological simulations of cluster formation, and confront them with radio surface brightness and spectral data of Coma. For standard assumptions, structure formation shocks lead to a seed electron population which produces too centrally concentrated radio emission. Matching observations requires modifying properties of the CR population (rapid streaming; enhanced CR electron acceleration at shocks) or turbulence (increasing turbulent-to-thermal energy density with radius), but at the expense of fine-tuning. In a parameter study, we find that radio properties are exponentially sensitive to the amplitude of turbulence, which is inconsistent with small scatter in scaling relations. This sensitivity is removed if we relate the acceleration time to the turbulent dissipation time. In this case, turbulence above a threshold value provides a fixed amount of amplification; observations could thus potentially constrain the unknown CR seed population. To obtain sufficient acceleration, the turbulent magneto-hydrodynamics cascade has to terminate by transit time damping on CRs, i.e., thermal particles must be scattered by plasma instabilities. Understanding the small scatter in radio halo scaling relations may provide a rich source of insight on plasma processes in clusters.
