Simulation Study on the Influence of High Toroidal Mode Number n=4 RMP Phases on Plasma Response
Creators: name: Lingjie Zhou, X.J.Zha
Publisher: name: Zenodo
Year: 2024

description: Based on the equilibrium constructed from the EAST device discharge 115766, this study employed a linear plasma response model computed with the MARS-F program to investigate the influence of different RMP coil phase angles, under conditions of equal RMP coil current and zero phase difference. Simulation results indicate that the deformation of the plasma, under the influence of RMP fields, occurs only within a thin layer at the plasma boundary, manifesting a typical edge-peeling-like response. Notably, the plasma response at an RMP phase angle of 180° was more pronounced than at 0°, demonstrating that even with the same phase difference, different RMP phase angles can lead to significant variations in plasma response. This study provides crucial theoretical guidance for the design of RMP coil currents and their application in controlling Edge Localized Modes (ELMs) experiments.

description: We propose that the expectation value of a circular BPS-Wilson loop in N=4 SUSYM can be calculated exactly, to all orders in a 1/N expansion and to all orders in g^2 N. Using the AdS/CFT duality, this result yields a prediction of the value of the string amplitude with a circular boundary to all orders in alpha' and to all orders in g_s. We then compare this result with string theory. We find that the gauge theory calculation, for large g^2 N and to all orders in the 1/N^2 expansion does agree with the leading string theory calculation, to all orders in g_s and to lowest order in alpha'. We also find a relation between the expectation value of any closed smooth Wilson loop and the loop related to it by an inversion that takes a point along the loop to infinity, and compare this result, again successfully, with string theory.

Malleability at the extreme nanoscale: Slow and fast quakes of few-body systems

description: We explore the malleability of ultra-small metal nanoparticles by means of ab initio calculations. It is revealed that, when strained, such nanoparticles exhibit complex behavior, including bifurcation between slow and fast quakes of their atomic structure, despite being few-body systems. We show the bifurcation to arise from the collapse of the nanoparticle's stiffness and a broken soft mode symmetry, and that whether a slow or fast quake occurs can be controlled by varying the amplitude of the externally applied strains. We predict that while energy is released abruptly in a fast quake, surprisingly, it continues to build up during a slow quake and that, in common with slow-slip geological earthquakes, the slow nanoparticle quake is a silent precursor to a fast "seismic" quake. We show that electrical conductance and force measurements can detect and distinguish between slow and fast quakes, opening the way for experiments and potential applications of these phenomena.

description: Das Bedecken des natürlichen Bodens mit Beton, Asphalt oder Steinen wird als Bodenversiegelung oder Flächenversiegelung bezeichnet. Dadurch ist der Boden fast oder komplett wasserdicht, wodurch Regenwasser nicht oder nur wenig versickern kann. Die Komponenten des Wasserkreislaufs werden ungünstig verändert. Der oberflächliche Abfluss ist verstärkt und kann bei Starkregen erhebliche Schäden verursachen. Auch der Gasaustausch des Bodens mit der ⁠Atmosphäre sowie weitere Prozesse im Boden werden gehemmt oder gestoppt. Die Bodenversiegelung nimmt v.a. in großen Städten nach wie vor besorgniserregend zu und trägt dort zu der stärkeren Erwärmung bei als im Umland; neue Techniken können Abhilfe schaffen. Soil sealing and changes in the natural water cycle: The covering of the natural soil with concrete, asphalt or stones is called soil sealing or surface sealing. As a result, the floor is almost or completely waterproof, which means that rainwater cannot or very little seepage. The components of the water cycle are changed unfavorably. The superficial runoff is increased and can cause considerable damage in heavy rain. The gas exchange between the soil and the atmosphere and other processes in the soil are also inhibited or stopped. Soil sealing continues to increase worryingly, especially in large cities, and contributes to its greater warming than in the surrounding area; new techniques can help. Sellado del suelo y cambios en el ciclo natural del agua: El recubrimiento del suelo natural con cemento, asfalto ó piedras se denomina sellado del suelos ó sellado de superficie. Como resultado, el suelo queda casi ó completamente sellado, lo que significa que el agua de lluvia no se filtra nada ó casi nada. El ciclo del agua local cambia negativamente. El flujo superficial del agua en caso de una lluvia fuerte aumenta y puede causar daños considerables. El intercambio de gases entre el suelo y la atmósfera asi como otros procesos dentro del suelo también se inhiben ó detienen. El sellado del suelo continúa aumentando de manera preocupante, especialmente en las grandes ciudades, y asi aportan significativamente a su mayor calentamiento que en las áreas circundantes.

Panel data analysis via mechanistic models

description: Panel data, also known as longitudinal data, consist of a collection of time series. Each time series, which could itself be multivariate, comprises a sequence of measurements taken on a distinct unit. Mechanistic modeling involves writing down scientifically motivated equations describing the collection of dynamic systems giving rise to the observations on each unit. A defining characteristic of panel systems is that the dynamic interaction between units should be negligible. Panel models therefore consist of a collection of independent stochastic processes, generally linked through shared parameters while also having unit-specific parameters. To give the scientist flexibility in model specification, we are motivated to develop a framework for inference on panel data permitting the consideration of arbitrary nonlinear, partially observed panel models. We build on iterated filtering techniques that provide likelihood-based inference on nonlinear partially observed Markov process models for time series data. Our methodology depends on the latent Markov process only through simulation; this plug-and-play property ensures applicability to a large class of models. We demonstrate our methodology on a toy example and two epidemiological case studies. We address inferential and computational issues arising due to the combination of model complexity and dataset size.

description: We consider three-partite pure states in the Hilbert space $\mathbb{C}^2 \otimes \mathbb{C}^m \otimes \mathbb{C}^n$ and investigate to which states a given state can be locally transformed with a non-vanishing probability. Whenever the initial and final states are elements of the same Hilbert space, the problem can be solved via the characterization of the entanglement classes which are determined via stochastic operations and classical communication (SLOCC). In general, there are infinitely many SLOCC classes. However, when considering transformations from higher- to lower-dimensional Hilbert spaces, an additional hierarchy among the classes can be found. This hierarchy of SLOCC classes coarse grains SLOCC classes which can be reached from a common resource state of higher dimension. We first show that a generic set of states in $\mathbb{C}^2 \otimes \mathbb{C}^m \otimes \mathbb{C}^n$ for $n=m$ is the union of infinitely many SLOCC classes, which can be parameterized by $m-3$ parameters. However, for $n \neq m$ there exists a single SLOCC class which is generic. Using this result, we then show that there is a full-measure set of states in $\mathbb{C}^2 \otimes \mathbb{C}^m \otimes \mathbb{C}^n$ such that any state within this set can be transformed locally to a full measure set of states in any lower-dimensional Hilbert space. We also investigate resource states, which can be transformed to any state (not excluding any zero-measure set) in the smaller-dimensional Hilbert space. We explicitly derive a state in $\mathbb{C}^2 \otimes \mathbb{C}^m \otimes \mathbb{C}^{2m-2}$ which is the optimal common resource of all states in $\mathbb{C}^2 \otimes \mathbb{C}^m \otimes \mathbb{C}^m$. We also show that for any $n < 2m$ it is impossible to reach all states in $\mathbb{C}^2 \otimes \mathbb{C}^m \otimes \mathbb{C}^{\tilde{n}}$ whenever $\tilde{n}>m$.

description: Introduction: Many semiarid regions around the world are presently experiencing significant changes in both climatic conditions and vegetation. This includes a disturbed coexistence between grasses and bushes also known as bush encroachment, and altered precipitation patterns with larger rain events. Fewer, more intense precipitation events might promote groundwater recharge, but depending on the structure of the vegetation also encourage further woody encroachment. Materials and Methods: In this study, we investigated how patterns and sources of water uptake of Acacia mellifera (blackthorn), an important encroaching woody plant in southern African savannas, are associated with the intensity of rain events and the size of individual shrubs. The study was conducted at a commercial cattle farm in the semiarid Kalahari in Namibia (MAP 250 mm/a). We used soil moisture dynamics in different depths and natural stable isotopes as markers of water sources. Xylem water of fifteen differently sized individuals during eight rain events was extracted using a Scholander pressure bomb. Results and Discussion: Results suggest the main rooting activity zone of A. mellifera in 50 and 75 cm soil depth but a reasonable water uptake from 10 and 25 cm. Any apparent uptake pattern seems to be driven by water availability, not time in the season. Bushes prefer the deeper soil layers after heavier rain events, indicating some evidence for the classical Walter’s two-layer hypothesis. However, rain events up to a threshold of 6 mm/day cause shallower depths of use and suggest several phases of intense competition with perennial grasses. The temporal uptake pattern does not depend on shrub size, suggesting a fast upwards water flow inside. d2H and d18O values in xylem water indicate that larger shrubs rely less on upper and very deep soil water than smaller shrubs. It supports the hypothesis that in environments where soil moisture is highly variable in the upper soil layers, the early investment in a deep tap-root to exploit deeper, more reliable water sources could reduce the probability of mortality during the establishment phase. Nevertheless, independent of size and time in the season, bushes do not compete with potential groundwater recharge. In a savanna encroached by A. mellifera, groundwater will most likely be affected indirectly.

description: Introduction Injury prevention programs (IPPs) are an inherent part of training in recreational and professional sports. Providing performance-enhancing benefits in addition to injury prevention may help adjust coaches and athletes’ attitudes towards implementation of injury prevention into daily routine. Conventional thinking by players and coaches alike seems to suggest that IPPs need to be specific to one’s sport to allow for performance enhancement. The systematic literature review aims to firstly determine the IPPs nature of exercises and whether they are specific to the sport or based on general conditioning. Secondly, can they demonstrate whether general, sports-specific or even mixed IPPs improve key performance indicators with the aim to better facilitate long-term implementation of these programs? Methods PubMed and Web of Science were electronically searched throughout March 2018. The inclusion criteria were randomized control trials, publication dates between Jan 2006 and Feb 2018, athletes (11–45 years), injury prevention programs and included predefined performance measures that could be categorized into balance, power, strength, speed/agility and endurance. The methodological quality of included articles was assessed with the Cochrane Collaboration assessment tools. Results Of 6619 initial findings, 22 studies met the inclusion criteria. In addition, reference lists unearthed a further 6 studies, making a total of 28. Nine studies used sports specific IPPs, eleven general and eight mixed prevention strategies. Overall, general programs ranged from 29–57% in their effectiveness across performance outcomes. Mixed IPPs improved in 80% balance outcomes but only 20–44% in others. Sports-specific programs led to larger scale improvements in balance (66%), power (83%), strength (75%), and speed/agility (62%). Conclusion Sports-specific IPPs have the strongest influence on most performance indices based on the significant improvement versus control groups. Other factors such as intensity, technical execution and compliance should be accounted for in future investigations in addition to exercise modality.

description: Nine recently discovered long-period comets were observed by the Solar Wind Anisotropies (SWAN) Lyman-alpha all-sky camera on board the Solar and Heliosphere Observatory (SOHO) satellite during the period of 2013 to 2016. These were C/2012 K1 (PanSTARRS), C/2013 US10 (Catalina), C/2013 V5 (Oukaimeden), C/2013 R1 (Lovejoy), C/2014 E2 (Jacques), C/2014 Q2 (Lovejoy), C/2015 G2 (MASTER), C/2014 Q1 (PanSTARRS) and C/2013 X1 (PanSTARRS). Of these 9 comets 6 were long-period comets and 3 were possibly dynamically new. Water production rates were calculated from each of the 885 images using our standard time-resolved model that accounts for the whole water photodissociation chain, exothermic velocities and collisional escape of H atoms. For most of these comets there were enough observations over a broad enough range of heliocentric distances to calculate power-law fits to the variation of production rate with heliocentric distances for pre- and post-perihelion portions of the orbits. Comet C/2014 Q1 (PanSTARRS), with a perihelion distance of only ~0.3 AU, showed the most unusual variation of water production rate with heliocentric distance and the resulting active area variation, indicating that when the comet was within 0.7 AU its activity was dominated by the continuous release of icy grains and chunks, greatly increasing the active sublimation area by more than a factor of 10 beyond what it had at larger heliocentric distances. A possible interpretation suggests that a large fraction of the comet's mass was lost during the apparition.

description: We compute the one-loop four-point function in {\cal N}=4 supersymmetric Yang-Mills theory with gauge group U(N). We perform the calculation in {\cal N}=1 superspace using the background field method and obtain the complete off-shell contributions to the effective action from planar and non planar supergraphs. In the low-energy approximation the result simplifies and we can study its properties under gauge transformations. It appears that the nonplanar contributions do not maintain the gauge invariance of the classical action.

description: This thesis discusses the development of a particle timing detector for an experiment searching for a new physics process not observed before. This new physics process produces a very clear signal in the form of a high momentum electron. The timing detector developed in this thesis aims to record when any high momentum particle passes through it to let other systems in the experiment know that a potential signal has come through in amongst many low momentum noise. It also provides a reference time to measure signal electrons. This thesis explains prototype design and construction of the detector and measurements made to see how well the detector will perform.

description: Motivation: One approach to inferring genetic regulatory structure from microarray measurements of mRNA transcript hybridization is to estimate the associations of gene expression levels measured in repeated samples. The associations may be estimated by correlation coefficients or by conditional frequencies (for discretized measurements) or by some other statistic. Although these procedures have been successfully applied to other areas, their validity when applied to microarray measurements has yet to be tested. Results: This paper describes an elementary statistical difficulty for all such procedures, no matter whether based on Bayesian updating, conditional independence testing, or other machine learning procedures such as simulated annealing or neural net pruning. The difficulty obtains if a number of cells from a common population are aggregated in a measurement of expression levels. Although there are special cases where the conditional associations are preserved under aggregation, in general inference of genetic regulatory structure based on conditional association is unwarranted.

description: Gesunde Böden sind außerordentlich arten- und individuenreiche Ökosysteme, deren vielfältige Leistungen für das menschliche Leben unerlässlich sind. Landwirtschaftliche Nutzung ist die Hauptursache für die Verarmung und den Verlust von Böden, der dramatische Ausmaße angenommen hat. Um dem entgegenzusteuern, ist ein interdisziplinäres Vorgehen unerlässlich. Entscheidungsträger:innen sind gefordert, mutige Entscheidungen auf Basis der Grenzen verfügbarer Ressourcen zu treffen anstatt wie bisher blind dem Wachstumsdogma zu folgen. Intensive agriculture and soil degradation: Healthy soils are ecosystems hosting extremely diverse and abundant communities whose manifold services are essential for human life. Agricultural land use is the prime cause for soil degradation and loss, which have reached an alarming rate. In order to counteract this, interdisciplinary approaches are indispensable. Decisionmakers are required to make courageous decisions based on planetary boundaries instead of continuing to blindly follow the dogma of growth. Agricultura intensiva y degradación del suelo: Los suelos sanos son ecosistemas extraordinariamente ricos en especies e individuos y cuyos diversos servicios son esenciales para la vida humana. El uso agrícola es la principal causa del empobrecimiento y pérdida de suelos, que ha alcanzado proporciones dramáticas. Para contrarrestar esto, es fundamental un enfoque interdisciplinario. Los responsables de la toma de decisiones se enfrentan al desafío de tomar decisiones valientes basadas en los límites de los recursos disponibles en lugar de seguir ciegamente el dogma del crecimiento como antes.

description: Recently it was conjectured that the strongly attractive antikaon--nucleon potential can result in the formation of antikaon nuclear bound states. We discuss the formation of such states as possible residues in heavy ion collisions. In this context, we calculate the excitation functions of single- and double-$K^-$ clusters in terms of the statistical thermal model. We show that, if such objects indeed exist, then, in heavy ion collisions, the single-$K^-$ clusters are most abundantly produced at present SIS energies, while the double-$K^-$ clusters show a pronounced maximum yield in the energy domain of the future accelerator at GSI. This is a direct consequence of: i) the baryonic dominance in low energy heavy ion collisions and the large baryonic content of the antikaonic bound states; ii) the strong energy dependence of strangeness production at low energies. The production yields of double-strange clusters is compared with that of double strange baryons. It is shown that at SIS energy there is a linear scaling relation of the $Ξ^-/K^+$ with $K^+/p$ yields ratio.

description: X-ray free-electron laser oscillator (XFELO) is expected to be a cutting edge tool for fully coherent X-ray laser generation, and undulator taper technique is well-known for considerably increasing the efficiency of free-electron lasers (FELs). In order to combine the advantages of these two schemes, FEL amplifier seeded by XFELO is proposed by simply using a chirped electron beam. With the right choice of the beam parameters, the bunch tail is within the gain bandwidth of XFELO, and lase to saturation, which will be served as a seeding for further amplification. Meanwhile, the bunch head which is outside the gain bandwidth of XFELO, is preserved and used in the following FEL amplifier. It is found that the natural "double-horn" beam current as well as residual energy chirp from chicane compressor are quite suitable for the new scheme. Inheriting the advantages from XFELO seeding and undulator tapering, it is feasible to generate nearly terawatt level, fully coherent X-ray pulses with unprecedented shot-to-shot stability, which might open up new scientific opportunities in various research fields.

description: In the very near future, weak lensing surveys will map the projected density of the universe in an unbiased way over large regions of the sky. In order to interpret the results of studies it is helpful to develop an understanding of the errors associated with quantities extracted from the observations. In a generalization of one of our earlier works, we present estimators of the cumulants and cumulant correlators of the weak lensing convergence field, and compute the variance associated with these estimators. By restricting ourselves to so-called compensated filters we are able to derive quite simple expressions for the errors on these estimates. We also separate contributions from cosmic variance, shot noise and intrinsic ellipticity of the source galaxies.

Temperature- dependence of anomalous Hall conductivity in Rashba-type ferromagnets

description: The applicability and usefulness of Rashba model have been extended by recent observations in the field of spintronics, such as the spin-orbit torque at the junction interfaces between ferromagnetic (FM) metals and non-magnetic (NM) metals and the perpendicular anomalous magnetoresistance (AMR) in heterostructures such as FI/NM or FM/NI (I denotes an insulator). In particular, the observations of the perpendicular AMR effect stimulate further interest in the Rashba-type spin-orbit interaction (SOI) at interfaces. Thus, the Rashba model with exchange splitting (EXS) is considered not only to play as an effective model for the physical understanding but also to reflect actual bi-layer systems in current spintronics devices. In the present work, we have first investigated the temperature dependence of anomalous Hall conductivity (AHC) of Rashba-type ferromagnets considered effects of spin fluctuations within the disordered local moment (DLM) scheme. The most distinctive feature that we observed is that intrinsic AHC increases with increasing temperature. This can be understood from the aspect of spin chirality, which indicates that the AHC increases with decreasing EXS when the SOI is much smaller than the EXS. The extrinsic part of the Fermi surface term also increases with increasing temperature and has a large contribution, comparable to that of the intrinsic part. Although, such a behaviour has not yet been observed experimentally, we suggest that the physical picture found in this work might lurk in an anomalous Hall effects in Rashbe-type ferromagnets.
