description: The utilization of epidural electrodes in the preoperative evaluation of intractable epilepsy is a valuable but underrepresented tool. In recent years, we have adapted the use of cylindrical epidural 1-contact electrodes (1-CE) instead of Peg electrodes. 1-CEs are more versatile since their explantation is a possible bedside procedure. Here we report our experience with 1-CEs as well as associated technical nuances. This retrospective analysis included 56 patients with intractable epilepsy who underwent epidural electrode placement for presurgical evaluation at the Department of Neurosurgery at the Charité University Hospital from September 2011 to July 2021. The median age at surgery was 36.3 years (range: 18–87), with 30 (53.6%) female and 26 (46.4%) male patients. Overall, 507 electrodes were implanted: 93 Fo electrodes, 33 depth electrodes, and 381 epidural electrodes, with a mean total surgical time of 100.5 ± 38 min and 11.8 ± 5 min per electrode. There was a total number of 24 complications in 21 patients (8 Fo electrode dislocations, 6 CSF leaks, 6 epidural electrode dislocations or malfunction, 3 wound infections, and 2 hemorrhages); 11 of these required revision surgery. The relative electrode complication rates were 3/222 (1.4%) in Peg electrodes and 3/159 (1.9%) in 1-CE. In summary, epidural recording via 1-CE is technically feasible, harbours an acceptable complication rate, and adequately replaces Peg electrodes.
On Calibration of Three-axis Magnetometer

description: Magnetometer has received wide applications in attitude determination and scientific measurements. Calibration is an important step for any practical magnetometer use. The most popular three-axis magnetometer calibration methods are attitude-independent and have been founded on an approximate maximum likelihood (ML) estimation with a quartic subjective function, derived from the fact that the magnitude of the calibrated measurements should be constant in a homogeneous magnetic field. This paper highlights the shortcomings of those popular methods and proposes to use the quadratic optimal ML estimation instead for magnetometer calibration. Simulation and test results show that the optimal ML calibration is superior to the approximate ML methods for magnetometer calibration in both accuracy and stability, especially for those situations without sufficient attitude excitation. The significant benefits deserve the moderately increased computation burden. The main conclusion obtained in the context of magnetometer in this paper is potentially applicable to various kinds of three-axis sensors.

description: As a revolutionary paradigm for controlling wireless channels, reconfigurable intelligent surfaces (RISs) have emerged as a candidate technology for future 6G networks. However, due to the "multiplicative fading" effect, the existing passive RISs only achieve limited capacity gains in many scenarios with strong direct links. In this paper, the concept of active RISs is proposed to overcome this fundamental limitation. Unlike passive RISs that reflect signals without amplification, active RISs can amplify the reflected signals via amplifiers integrated into their elements. To characterize the signal amplification and incorporate the noise introduced by the active components, we develop and verify the signal model of active RISs through the experimental measurements based on a fabricated active RIS element. Based on the verified signal model, we further analyze the asymptotic performance of active RISs to reveal the substantial capacity gain they provide for wireless communications. Finally, we formulate the sum-rate maximization problem for an active RIS aided multi-user multiple-input single-output (MU-MISO) system and a joint transmit beamforming and reflect precoding scheme is proposed to solve this problem. Simulation results show that, in a typical wireless system, passive RISs can realize only a limited sum-rate gain of 22%, while active RISs can achieve a significant sum-rate gain of 130%, thus overcoming the "multiplicative fading" effect.

WAdS$_3$/CFT$_2$ correspondence in presence of bulk massive gravitons

description: In a previous paper, it has been shown that the entropy of non-extremal black holes in Warped Anti-de Sitter (WAdS) spaces in massive gravity can be computed microscopically in terms of a dual conformal field theory. Here, we extend this computation to a set of asymptotic boundary conditions that, while still gathering the WAdS$_3$ black holes, also allow for new solutions that are not locally equivalent to WAdS$_3$ space, and therefore are associated to the local degrees of freedom of the theory (bulk massive gravitons). After presenting explicit examples of such geometries, we compute the asymptotic charge algebra and show that it is generated by the semi-direct sum of Virasoro algebra and an affine Kac-Moody algebra. The value of the central charge turns out to be exactly the one that leads to reproduce the entropy of the WAdS$_3$ black holes. This result probes the WAdS$_3$/CFT$_2$ correspondence in presence of bulk gravitons.

The Influence of Reduced Muscle Quality on Muscular Dimensional Changes and Performance: Implications for the Elderly and Obese
Creators: name: Giuliani, Hayden
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Muscle quality has been suggested to contribute to the age-related decline in muscle function, which is exacerbated by obesity. Although the mechanism is unknown, it may be due to a reduction in muscular dimensional changes with contraction. The purpose of the present study was to determine if the dimensional changes during contraction is influenced by intramuscular fat, and its relationship to muscle strength and performance. Forty-nine males were categorized into three groups by BMI and age. Participants completed a walking test, a maximal and submaximal isometric strength assessment, while ultrasonography was used to determine muscular dimensions. Muscle size decreased (P<0.045) across torque intensities in the young group, but not in the older men (P>0.410). A greater change in muscle size was correlated with faster walking speed (r=-0.377,P=0.013), but not muscle quality or strength. Future studies are needed to determine which non-contractile tissues contribute to the alterations in muscular dimension changes.
The Resurgence of the Korean War Blockbuster in Chinese Cinema: How China Uses the Korean War to Promote Nationalism

subject: Propaganda films

description: Korean War films were a popular source of propaganda in Maoist China. The genre declined after Mao’s death, but there has been a recent resurgence of Korean War films under Xi Jinping. The purpose of this thesis is to examine how these new films are upholding and reshaping elements of the Korean War narrative, and what this means for modern Chinese nationalism. To date, there has been no comprehensive study examining the Chinese cinematic Korean War narrative from Mao to the recent blockbusters under Xi. This thesis therefore charts trends in the evolution of film depictions of the Korean War in China by focusing on changing portrayals of the in-group and out-group across three periods: 1) Mao’s leadership; 2) 1980s to 2016; and 3) Xi Jinping’s leadership. Across the Maoist period and the recent resurgence under Xi, the in-group and out-group largely corresponds to the loyal Chinese soldier and the American imperialist adversary. While the virtuous Chinese in-group has remained fairly consistent in its presentation – with the notable exception of whether to include or exclude North Korean characters within this group – the American adversary has evolved from a nondescript menace to a more fully defined character. This reflects the cinematic Korean War narrative’s interaction with the Century of Humiliation narrative, changing Sino-American relations, and the achievements Xi is seeking to claim in advancing China’s modernization and development.

description: This paper presents a physical interface for collaborative mobile manipulators in industrial manufacturing and logistics applications. The proposed work builds on our earlier MOCA-MAN interface, through which an operator could be physically coupled to a mobile manipulator to be assisted in performing daily activities. The previous interface was based on a magnetic clamp attached to one arm of the user for the coupling stage, and a bracelet based on EMG sensors on the other arm for human-robot communication via gestures. The new interface instead presents the following additions: i) An industrial-like design that allows the worker to couple/decouple easily and to operate mobile manipulators locally; ii) A simplistic communication channel via a simple buttons board that allows controlling the robot with one hand only; iii) The interface offers enhanced loco-manipulation capabilities that do not compromise the worker mobility. In addition, an experimental evaluation with six human subjects is carried out to analyze the enhanced locomotion and flexibility of the proposed interface in terms of mobility constraint, usability, and physical load reduction.

description: This is the first in a series of papers constructing geometric models of twisted differential K-theory. In this paper we construct a model of even twisted differential K-theory when the underlying topological twist represents a torsion class. By differential twists we will mean smooth U(1)-gerbes with connection, and we use twisted vector bundles with connection as cocycles. The model we construct satisfies the axioms of Kahle and Valentino, including functoriality, naturality of twists, and the hexagon diagram. This paper confirms a long-standing hypothetical idea that twisted vector bundles with connection define twisted differential K-theory.

description: α-Lipoic acid is a potent antioxidant, and also an essential cofactor for PDH and α-KDH complexes in mitochondria. Investigations have shown complex human diseases are associated with oxidative stress. As preventative and therapeutic purposes, studies have evaluated effects of lipoic acid on complex human diseases, however, its molecular mechanisms and effects remained unknown. In this study, we examined the effects of heterozygous Lias deficiency on LPS induced inflammation and adrenergic agonist induced cardiac hypertrophy. We observed increased sensitivity of Lias heterozygous mice with elevation of TNF-α, decreased and delayed recovery of leukocyte and platelet counts accompanied with liver necrosis lung inflammation on LPS stimuli. Upon adrenergic agonist stimulation, both genotypes developed hypertrophy with increased HW/BW ratio and fibrosis in the heart, however, we observed protective effect of Lias deficiency upon stimulation. Our data indicates that Lias deficiency results in increased sensitivity upon LPS stimulation, however, protective effect against cardiac stimulation.

description: Let E be a Real or Quaternionic Hermitian vector bundle over a Klein surface M. We study the action of the gauge group of E on the space of Galois-invariant unitary connections and we show that the closure of a semi-stable orbit contains a unique unitary orbit of projectively flat, Galois-invariant connections. We then use this invariant-theoretic perspective to prove a version of the Narasimhan-Seshadri correspondence in this context: S-equivalence classes of semi-stable Real and Quaternionic vector bundes are in bijective correspondence with equivalence classes of certain appropriate representations of orbifold fundamental groups of Real Seifert manifolds over the Klein surface M.

description: This paper proposes a novel integrated dynamic method based on Behavior Trees for planning and allocating tasks in mixed human robot teams, suitable for manufacturing environments. The Behavior Tree formulation allows encoding a single job as a compound of different tasks with temporal and logic constraints. In this way, instead of the well-studied offline centralized optimization problem, the role allocation problem is solved with multiple simplified online optimization sub-problem, without complex and cross-schedule task dependencies. These sub-problems are defined as Mixed-Integer Linear Programs, that, according to the worker-actions related costs and the workers' availability, allocate the yet-to-execute tasks among the available workers. To characterize the behavior of the developed method, we opted to perform different simulation experiments in which the results of the action-worker allocation and computational complexity are evaluated. The obtained results, due to the nature of the algorithm and to the possibility of simulating the agents' behavior, should describe well also how the algorithm performs in real experiments.

Equivalence of Single-server and Multiple-servers Blind Quantum Computation Protocols

Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Because quantum computers are expensive, it is envisaged that individuals who want to utilize them would do so by delegating their calculations to someone who has a quantum computer. When quantum computer users delegate computations to quantum servers, they wish to keep information about their calculations hidden from the servers. The protocol of delegating a calculation while hiding information about the calculation from the server is called {\sl blind quantum computation protocol}. Prior research on single-server's blind quantum computation protocol required users to have quantum capabilities. Prior research on multiple-servers' blind quantum computation protocols required users to have just classical capabilities but imposed limits on the server-to-server communication. There are no known single-server blind quantum computation protocols with a classical user and multiple-servers blind quantum computation protocols that allows servers to communicate freely with each other. We show that the existence of these protocols is equivalence.

description: Background Analyzing kinematic and video data can help identify potentially erroneous motions that lead to sub-optimal surgeon performance and safety-critical events in robot-assisted surgery. Methods We develop a rubric for identifying task and gesture-specific Executional and Procedural errors and evaluate dry-lab demonstrations of Suturing and Needle Passing tasks from the JIGSAWS dataset. We characterize erroneous parts of demonstrations by labeling video data, and use distribution similarity analysis and trajectory averaging on kinematic data to identify parameters that distinguish erroneous gestures. Results Executional error frequency varies by task and gesture, and correlates with skill level. Some predominant error modes in each gesture are distinguishable by analyzing error-specific kinematic parameters. Procedural errors could lead to lower performance scores and increased demonstration times but also depend on surgical style. Conclusions This study provides insights into context-dependent errors that can be used to design automated error detection mechanisms and improve training and skill assessment.

description: Inspired by the classical spectral analysis of birth-death chains using orthogonal polynomials, we study an analogous set of constructions in the context of open quantum dynamics and related walks. In such setting, block tridiagonal matrices and matrix-valued orthogonal polynomials are the natural objects to be considered. We recall the problems of the existence of a matrix of measures or weight matrix together with concrete calculations of basic statistics of the walk, such as site recurrence and first passage time probabilities, with these notions being defined in terms of a quantum trajectories formalism. The discussion concentrates on the models of quantum Markov chains, due to S. Gudder, and on the particular class of open quantum walks, due to S. Attal et al. The folding trick for birth-death chains on the integers is revisited in this setting together with applications of the matrix-valued Stieltjes transform associated with the measures, thus extending recent results on the subject. Finally, we consider the case of non-symmetric weight matrices and explore some examples.
The uniqueness of environmental policy in the European context

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: The purpose of this thesis is to demonstrate the unique qualities of the environmental policy sector in the European context and what this means for European integration. This begins with a theoretical discussion of European integration, focused on differences between neofunctionalist and intergovernmental perspectives, also discussing how environmental policy fits into the dialogue. Following this is a brief discussion of the history and the guiding principles of the field that inform the institutionalization of environmental ideals in Europe. Next is a discussion of some important examples of policies, regulations and institutions involved in European environmental policy that demonstrate the institutionalization of environmental ideals. Finally, there is a comparison of the EU and the US from a federalist perspective to gauge the degree of environmental policy centralization in the EU. This demonstrates that the EU, not the US is the more centralized polity in terms of environmental policy.

description: The purpose of this study was to discover how university administrators believe adding college football will benefit their school and to investigate to what degree those anticipated benefits were realized. The research utilized branding theory to identify benefits commonly derived from football programs. University Presidents, Provosts, Athletic Directors, Senior Woman Administrators, and Faculty Athletic Representatives at NCAA Division I, II, & III member institutions who added college football in the 2001-2011 period were asked to participate in an on-line survey. The primary motivations for adding football were increasing undergraduate enrollment, increasing the amount of initial applications, and improving school spirit. Improving the proportion of male students on campus was also a university goal. Student-athlete participation opportunities, school spirit, the amount of initial applications for admission, and undergraduate enrollment all increased after adding football. This study serves as an aid to the many athletic departments currently contemplating whether to add football.

description: Motivated by recent trapped-ion quantum simulation experiments, we carry out a comprehensive study of the phase diagram of a spin-1 chain with XXZ-type interactions that decay as $1/r^α$, using a combination of finite and infinite-size DMRG calculations, spin-wave analysis, and field theory. In the absence of long-range interactions, varying the spin-coupling anisotropy leads to four distinct phases: a ferromagnetic Ising phase, a disordered XY phase, a topological Haldane phase, and an antiferromagnetic Ising phase. If long-range interactions are antiferromagnetic and thus frustrated, we find primarily a quantitative change of the phase boundaries. On the other hand, ferromagnetic (non-frustrated) long-range interactions qualitatively impact the entire phase diagram. Importantly, for $α\lesssim3$, long-range interactions destroy the Haldane phase, break the conformal symmetry of the XY phase, give rise to a new phase that spontaneously breaks a $U(1)$ continuous symmetry, and introduce an exotic tricritical point with no direct parallel in short-range interacting spin chains. We show that the main signatures of all five phases found could be observed experimentally in the near future.

description: While there has been a number of studies on Zero-Shot Learning (ZSL) for 2D images, its application to 3D data is still recent and scarce, with just a few methods limited to classification. We present the first generative approach for both ZSL and Generalized ZSL (GZSL) on 3D data, that can handle both classification and, for the first time, semantic segmentation. We show that it reaches or outperforms the state of the art on ModelNet40 classification for both inductive ZSL and inductive GZSL. For semantic segmentation, we created three benchmarks for evaluating this new ZSL task, using S3DIS, ScanNet and SemanticKITTI. Our experiments show that our method outperforms strong baselines, which we additionally propose for this task.

description: In preprocessing tensor-valued data, e.g. images and videos, a common procedure is to vectorize the observations and subject the resulting vectors to one of the many methods used for independent component analysis (ICA). However, the tensor structure of the original data is lost in the vectorization and, as a more suitable alternative, we propose the matrix- and tensor fourth order blind identification (MFOBI and TFOBI). In these tensorial extensions of the classic fourth order blind identification (FOBI) we assume a Kronecker structure for the mixing and perform FOBI simultaneously on each direction of the observed tensors. We discuss the theory and assumptions behind MFOBI and TFOBI and provide two different algorithms and related estimates of the unmixing matrices along with their asymptotic properties. Finally, simulations are used to compare the method's performance with that of classical FOBI for vectorized data and we end with a real data clustering example.

description: This paper applies existing and new approaches to study trends in the performance of elite athletes over time. We study both track and field scores of men and women athletes on a yearly basis from 2001 to 2019, revealing several trends and findings. First, we perform a detailed regression study to reveal the existence of an "Olympic effect", where average performance improves during Olympic years. Next, we study the rate of change in athlete performance and fail to reject the notion that athlete scores are leveling off, at least among the top 100 annual scores. Third, we examine the relationship in performance trends among men and women's categories of the same event, revealing striking similarity, together with some anomalous events. Finally, we analyze the geographic composition of the world's top athletes, attempting to understand how the diversity by country and continent varies over time across events. We challenge a widely held conception of athletics, that certain events are more geographically dominated than others. Our methods and findings could be applied more generally to identify evolutionary dynamics in group performance and highlight spatio-temporal trends in group composition.

description: A comparative content analysis examined the use of graphics as promotional tools by cable networks. The cable networks chosen for analysis were USA, TNT, Nickelodeon, and the Disney Channel. Comparisons of the use of graphics by these cable networks were made based on target audiences and business models. Key findings included the use of graphics to drive viewers to social media by the adult-targeted networks and the exclusive use of graphics to promote programming by the non-ad-supported network. In addition, the study revealed that programming-related graphics were used predominantly to retain viewers on the child-targeted networks and to drive viewers to programming considered to be a priority on the adult-targeted networks.

description: Here we propose another type of ferromagnetic semiconductors: ferromagnetic negative charge-transfer insulator (FNCTI). In FNCTI, the negative charge-transfer states strongly enhance the ferromagnetic (FM) exchange interactions and the orbital hybridization gap permits the magnetic molecular orbitals as the underlying magnetic units rather than local atomic orbitals. Thus the FM exchange interactions are rather strong and decay slowly due to the large spearding of magnetic molecular orbitals. This is distinct from the superexchange mechanism where FM exchange interactions are quite weak as summarized in the well-known Goodenough-Kanamori-Anderson semi-empirical rules.Through first-principle calculations with the hybrid functional, PbO-type CrAs monolayer is mapped out to be a FNCTI, which possesses a band gap $\sim$ 0.35 eV, FM nearest-/next-nearest-neighbor exchange coupling strength $\sim$ 57/40 meV, and a high $T_c$ $\sim$ 1500 K respectively. It is believed that the existence of FNCTI validates the long-pending hypothesis by D. I. Khomskii and G. A. Sawatzky in 1997 [Solid State Commun. 102, 87 (1997)].

description: Causal structure learning refers to a process of identifying causal structures from observational data, and it can have multiple applications in biomedicine and health care. This paper provides a practical review and tutorial on scalable causal structure learning models with examples of real-world data to help health care audiences understand and apply them. We reviewed traditional (combinatorial and score-based methods) for causal structure discovery and machine learning-based schemes. We also highlighted recent developments in biomedicine where causal structure learning can be applied to discover structures such as gene networks, brain connectivity networks, and those in cancer epidemiology. We also compared the performance of traditional and machine learning-based algorithms for causal discovery over some benchmark data sets. Machine learning-based approaches, including deep learning, have many advantages over traditional approaches, such as scalability, including a greater number of variables, and potentially being applied in a wide range of biomedical applications, such as genetics, if sufficient data are available. Furthermore, these models are more flexible than traditional models and are poised to positively affect many applications in the future.
"Finding balance through compromising". A grounded theory explaining evidence-based practice by course leaders in a small-specialist land-based higher education institution
Creators: name: van Veggel, Nieky

Subjects: Higher education

description: The context of this research is course leadership in small specialist higher education institutions. Course leaders are pivotal members of the academic team, whose role bridges the interests of all institutional stakeholders. In small-specialist HEIs, course leader roles typically include pastoral care of students, curriculum development, quality assurance, admissions, course marketing and mentoring of colleagues. Despite the importance of this role, course leadership is under-researched. The limited research available focuses on the role itself, rather than course leader practice, with scant recognition of how course leaders use EBP. The purpose of this research is therefore to explain how course leaders use evidence to inform their practice in small-specialist HEIs.
 This study took a grounded theory approach to investigate evidence-based course leadership. Semi-structured interviews were held after which transcripts were coded and analysed through constant comparison and intensive memoing. The substantive theory “Finding balance through compromising” emerged from the data. This theory consists of three core categories: “finding balance”, “compromising” and “feeling undervalued”.
 The findings show that “compromising” takes place within the course leader role, between the course leader role and other roles held by the course leader within the small-specialist institution, and between the course leader’s professional and personal lives. Due to the underpinning factor “feeling undervalued”, course leaders rely on experience and institutional data, but not peer-reviewed evidence to inform their course leader practice, even though they do use these for their teaching practice. Course leaders explained that a lack of professional development, a lack of recognition and a lack of resources were the main causes for compromising, and that favouring experience-based practice over EBP is a means to find balance.
 Based on these findings, increasing EBP by course leaders will require institutional support through appropriate CPD opportunities, institutional recognition of the course leader role, and availability of resources. When these factors are integrated into institutional policy and practice, course leaders will need to compromise less, leading to EBP by course leaders, which will benefit all stakeholders.

description: We study intrinsic DC spin and valley Hall conductivity in doped ferromagnetic silicene in the presence of an electric filed applied perpendicular to silicene sheet. By calculating its energy spectrum and wavefunction and by making use of Kubo formalism, we obtain a general relation for the transverse Hall conductivity which can be used to obtain spin- and valley-Hall conductivity. Our results, in the zero limit of the exchange field, reduces to the previous results. Furthermore we discuss electrically tunable spin and valley polarized transport in ferromagnetic silicene and obtain the necessary conditions for observing a fully spin or valley polarized transport.

 Holzhammer (1956) indicated the specimen “ P. G. Lorentz & G. H. Hieronymus 705” as “ typus varietatis”, but this was in fact a lectotypification since the protologue mentioned two specimens (see Art. 7.10): “ Argentinien, Sierra de Tucuman, La Cienaga, I. 1874 (G. Hieronymus et P. G. Lorentz, Flora Argent. n. 705). Paraguay, Tobati, bei Cerro Aparepy. Toniger Camp. Vulgärname „Batatilla “ wegen der batatenähnlichen Wurzelknolle (K. Fiebrig. PI. parag. n. 796)”.
 Suessenguth’s types are mainly housed at M, but this particular collection was not traced, neither at M nor at B. Actually, there are duplicates of this collection at GOET (code 015489) and CORD (code 00002558) but none of both specimens bear an indication that Holzhammer has examined it. Considering the Art. 9.17, Holzhammer’s indication should be narrowed to one single specimen in a subsequent lectotypification. According to Stafleu & Cowan (1981), Lorentz types are housed at GOET, therefore the specimen GOET-015489 is designated here as a second-step lectotype of the name Gomphrena elegans var. claussenioides.
