description: A "tournament sequence" is an increasing sequence of positive integers (t_1,t_2,...) such that t_1=1 and t_{i+1} <= 2 t_i. A "Meeussen sequence" is an increasing sequence of positive integers (m_1,m_2,...) such that m_1=1, every nonnegative integer is the sum of a subset of the {m_i}, and each integer m_i-1 is the sum of a unique such subset. We show that these two properties are isomorphic. That is, we present a bijection between tournament and Meeussen sequences which respects the natural tree structure on each set. We also present an efficient technique for counting the number of tournament sequences of length n, and discuss the asymptotic growth of this number. The counting technique we introduce is suitable for application to other well-behaved counting problems of the same sort where a closed form or generating function cannot be found.

description: The so-called stellar formalism allows to represent the non-Gaussian properties of single-mode quantum states by the distribution of the zeros of their Husimi Q-function in phase-space. We use this representation in order to derive an infinite hierarchy of single-mode states based on the number of zeros of the Husimi Q-function, the stellar hierarchy. We give an operational characterisation of the states in this hierarchy with the minimal number of single-photon additions needed to engineer them, and derive equivalence classes under Gaussian unitary operations. We study in detail the topological properties of this hierarchy with respect to the trace norm, and discuss implications for non-Gaussian state engineering and continuous variable quantum computing.

description: Excessive anthropogenic nutrient input has resulted in eutrophication and algal blooms which have severely impacted the function and sustainability of aquatic ecosystems, underscoring the need to implement nutrient management strategies. It was assumed that the increasing rainfall during flood season would affect the stoichiometric ratio of total nitrogen (TN): total phosphorus (TP), driving the nutrient limitation of algal growth. In order to test this concept and explore corresponding nutrient management strategies, nutrient addition bioassays were carried out in Xiangxi Bay, one of the largest tributaries of the Three Gorges Reservoir (TGR), China. Results indicated that nutrient limitation on algal growth fluctuated from nitrogen (N) to phosphorus (P) limitation. N limitation dominated in the early flood season. However, the reduction of dissolved P, accompanied with an increase of TN: TP caused by an increase in extreme rainfall events intensified P limitation throughout the bay. Then P limitation was alleviated due to the reduction of rainfall and the process of impoundment after the flood season. The variation of TN: TP caused by the increasing of rainfall and flooding could be the main driving factor of the nutrient limitation shift in aquatic ecosystems mainly affected by external nutrient inputs. Nutrient dilution and enrichment bioassays showed that TN and TP concentration thresholds should be targeted at below 0.55 mg/L and 0.057 ∼ 0.064 mg/L respectively, to limit the growth of algae and maintain chlorophyll a below 30 μg/L. Dual nutrient (N & P) reductions were required for long-term bloom mitigation in the entire basin. This study provided a scientific basis for a nutrient management strategy to combat eutrophication and reduce algal bloom potentials in the tributaries of the TGR. We recommend that long-term determinations of nutrient limitation and nutrient threshold will be needed to control algal growth, considering future anticipated changes in land use, population density and the impacts of climate change.
Field-Selective Anomaly and Chiral Mode Reversal in Type-II Weyl Materials

description: Three-dimensional condensed matter incarnations of Weyl fermions generically have a tilted dispersion—in sharp contrast to their elusive high-energy relatives where a tilt is forbidden by Lorentz invariance, and with the low- energy excitations of two-dimensional graphene sheets where a tilt is forbidden by either crystalline or particle-hole symmetry. Very recently, a number of materials (MoTe2, LaAlGe, and WTe2) have been identified as hosts of so-called type-II Weyl fermions whose dispersion is so strongly tilted that a Fermi surface is formed, whereby the Weyl node becomes a singular point connecting electron and hole pockets. We here predict that these systems have remarkable properties in the presence of magnetic fields. Most saliently, we show that the nature of the chiral anomaly depends crucially on the relative angle between the applied field and the tilt, and that an inversion-asymmetric overtilting creates an imbalance in the number of chiral modes with positive and negative slopes. The field-selective anomaly gives a novel magneto-optical resonance, providing an experimental way to detect concealed Weyl nodes.

description: The roasting process is the most important process in forming complex flavors and aromas in processed coffee-based drinks. Different temperatures and roasting times result in different qualities of Arabica coffee. The temperature and length of roasting time vary depending on the system and type of roasting machine used to maintain the quality of the coffee in terms of coffee color and most importantly in terms of the desired coffee taste. This research aims to determine the physical quality characteristics of Arabica coffee beans roasted in Simalungun Regency, North Sumatra. The material used is the Gayo variety of red cherry Arabica coffee fruit which is processed into green beans using the semi-wet method. Roasting uses a William Edison brand W600i SE roasting machine with varying temperatures (160 0C, 170 0C, and 180 0C) and length of time (14 minutes, 17 minutes, and 20 minutes). The parameters observed include the physical quality characteristics of roasted coffee, including yield, water content, acidity and color. The research results showed that the average yield value of coffee beans after roasting was 87.85%, the average water content was 3.09%, the pH value ranged from 4.76 – 5.32, and the color varied predominantly from brown.
Dynamics near Relative Equilibria: Nongeneric Momenta at a 1:1 Group-Reduced Resonance

description: An interesting situation occurs when the linearized dynamics of the shape of a formally stable Hamiltonian relative equilibrium at nongeneric momentum 1:1 resonates with a frequency of the relative equilibrium's generator. In this case some of the shape variables couple to the group variables to first order in the momentum perturbation, and the first order perturbation theory implies that the relative equilibrium slowly changes orientation in the same way that a charged particle with magnetic moment moves on a sphere under the influence of a radial magnetic monopole. In the course of showing this a normal form is constructed for linearizations of relative equilibria and for Hamiltonians near group orbits of relative equilibria.

description: The Compact Linear Collider (CLIC) is a TeV-scale high-luminosity linear $e^+e^-$ collider under development by international collaborations hosted by CERN. This document provides an overview of the design, technology, and implementation aspects of the CLIC accelerator. For an optimal exploitation of its physics potential, CLIC is foreseen to be built and operated in stages, at centre-of-mass energies of 380 GeV, 1.5 TeV and 3 TeV, for a site length ranging between 11 km and 50 km. CLIC uses a Two-Beam acceleration scheme, in which normal-conducting high-gradient 12 GHz accelerating structures are powered via a high-current Drive Beam. For the first stage, an alternative with X-band klystron powering is also considered. CLIC accelerator optimisation, technical developments, and system tests have resulted insignificant progress in recent years. Moreover, this has led to an increased energy efficiency and reduced power consumption of around 170 MW for the 380 GeV stage, together with a reduced cost estimate of approximately 6 billion CHF. The construction of the first CLIC energy stage could start as early as 2026 and first beams would be available by 2035, marking the beginning of a physics programme spanning 25-30 years and providing excellent sensitivity to Beyond Standard Model physics, through direct searches and via a broad set of precision measurements of Standard Model processes, particularly in the Higgs and top-quark sectors.

description: We consider the following class of unitary representations $π$ of some (real) Lie group $G$ which has a matched pair of symmetries described as follows: (i) Suppose $G$ has a period-2 automorphism $τ$, and that the Hilbert space $\mathbf{H} (π)$ carries a unitary operator $J$ such that $Jπ=(π\circ τ)J$ (i.e., selfsimilarity). (ii) An added symmetry is implied if $\mathbf{H} (π)$ further contains a closed subspace $\mathbf{K}_0 $ having a certain order-covariance property, and satisfying the $\mathbf{K}_0 $-restricted positivity: $< v \mid Jv > \ge 0$, $\forall v\in \mathbf{K}_0 $, where $< \cdot \mid \cdot >$ is the inner product in $\mathbf{H} (π)$. From (i)--(ii), we get an induced dual representation of an associated dual group $G^c$. All three properties, selfsimilarity, order-covariance, and positivity, are satisfied in a natural context when $G$ is semisimple and hermitean; but when $G$ is the $(ax+b)$-group, or the Heisenberg group, positivity is incompatible with the other two axioms for the infinite-dimensional irreducible representations. We describe a class of $G$, containing the latter two, which admits a classification of the possible spaces $\mathbf{K}_0 \subset \mathbf{H} (π)$ satisfying the axioms of selfsimilarity and order-covariance.

Confinement of Non-neutral Plasmas in Stellarator Magnetic Surfaces

description: The Columbia Non-neutral Torus (CNT) is the first experiment designed to create and study small Debye length non-neutral plasmas confined by magnetic surfaces.   This thesis describes experimental confinement studies of non-neutral plasmas on magnetic surfaces in CNT. Open orbits exist in CNT resulting in electron loss rates that are much faster than initially predicted.  For this reason a conforming boundary was designed and installed to address what is believed to be the primary cause of open orbits: the existence of a sizable mismatch between the electrostatic potential surfaces and the magnetic surfaces.  After installation a record confinement time of 337 ms was measured, more than an order of magnitude improvement over the previous 20 ms record.  This improvement was a combination of the predicted improvement in orbit quality, a reduced Debye length that resulted in decreased transport due to the perturbing insulated rods, and improved operating parameters not indicative of any new physics. The perturbation caused by the insulated rods that hold emitters on axis in CNT is a source of electron transport and would provide a loss mechanism for positrons in future positron-electron plasma experiments.  For these reasons an emitter capable of creating plasmas then being removed faster than the confinement time was built and installed.  Measurements of plasma decay after emitter retraction indicate that ion accumulation reduces the length of time that plasmas are confined.  Plasmas have been measured after retraction with decay times as long as 92 ms after the emitter has left the last closed flux surface. Experimental observations show that obstructing one side of an emitting filament with a nearby insulator substantially improves confinement.  As a result, experiments have been performed to determine whether a two stream instability affects confinement in CNT.  Results indicate that the improvement is not caused by reducing a two stream instability.  Instead, the improvement is a result of altering the sheath of the emitting filament which allows the plasma to reach an equilibrium state with improved confinement.  These measurements agree with confinement times for plasmas created by unobstructed emission that are in the same improved confinement state.

description: In the present work the Calderbank-Pedersen description of four dimensional manifolds with self-dual Weyl tensor is used to obtain examples of quaternionic-kahler metrics with two commuting isometries. The eigenfunctions of the hyperbolic laplacian are found by use of Backglund transformations acting over solutions of the Ward monopole equation. The Bryant-Salamon construction of $G_2$ holonomy metrics arising as $R^3$ bundles over quaternionic-kahler base spaces is applied to this examples to find internal spaces of the M-theory that leads to an N=1 supersymmetry in four dimensions. Type IIA solutions will be obtained too by reduction along one of the isometries. The torus symmetry of the base spaces is extended to the total ones.

description: Background: Thioguanine is associated with liver toxicity, especially nodular regenerative hyperplasia (NRH). We assessed if liver histology alters during long-term maintenance treatment with thioguanine in patients with inflammatory bowel disease (IBD). Methods: Liver specimens of thioguanine treated IBD patients with at least two liver biopsies were revised by two independent liver pathologists, blinded to clinical characteristics. Alterations in histopathological findings between first and sequential liver specimen were evaluated and associated clinical data, including laboratory parameters and abdominal imaging reports, were collected. Results: Twenty-five IBD patients underwent sequential liver biopsies prior to, at time of, or after cessation of thioguanine treatment. The median time between the first and second biopsy was 25 months (range: 14–54). Except for one normal liver specimen, any degree of irregularities including inflammation, steatosis, fibrosis and some vascular disturbances were observed in the biopsies. The rates of perisinusoidal fibrosis (91%), sinusoidal dilatation (68%) and nodularity (18%) were the same in the first and second liver biopsies. A trend towards statistical significance was observed for phlebosclerosis (36% of the first vs. 68% of the second biopsies, p = .092). Presence of histopathological liver abnormalities was not associated with clinical outcomes. Furthermore, two patients in this cohort had portal hypertension in presence of phlebosclerosis. In another two patients, nodularity of the liver resolved upon thioguanine withdrawal. Conclusion: Vascular abnormalities of the liver were commonly observed in thioguanine treated IBD patients, although these were not progressive and remained of limited clinical relevance over time.

description: This research examined the political narratives of national leaders regarding an international border dispute between Costa Rica and Nicaragua from 2010-2015 and the subsequent social relations in an affected border village known as Delta, Costa Rica. Based on eighteen months of qualitative and quantitative ethnographic research conducted on the binational border, this work documents political discourses about the conflicted territory, referred to as Isla Calero or Isla Portillos, through first-hand interviews with national figures and military officials central to the conflict. These discourses are then juxtaposed to the lived realities in the village through an ethnographic analysis of social relations and community happenings amid this conflict. Particular attention is paid to the patrón-peon relationship between Costa Rican farm owners and Nicaraguan migrant workers, and how this relation exists in the midst of an unprecedented influx of police, military personnel, and security infrastructure beginning in 2010. To accomplish this goal, the first section of this work provides a detailed report of the rapid changes and security developments that took place in the community of Delta, Costa Rica. An analysis of the different political discourses and narratives to justify these rapid actions follows. The local reality of how this conflict was experienced by villagers of Delta, Costa Rica comprises the second half of this work in the form of an ethnographic account of the social relations and daily interactions between landowners, migrant workers, and the National Police in the border community. The findings highlight the disconnect between national-level political narratives and local experiences of conflict and how a transborder identity supersedes constructed barriers based on nationality, race, ethnicity, language, and even notions of (il)legality.

 Annotation: This monotypic genus, which is only known from El Hierro (type locality: Las Montañetas), the smallest and westernmost island of the Canaries, is only mentioned for the sake of completeness [it is neither considered in the tabular synopsis (Figs 2A–22D) nor in the key]. From today’s perspective, it can be deduced from its habitus and from the describing author’s unsuccessful search for further specimens at the type locality (the description was based on one individual) that the species does not belong to the Canarian fauna. Presumably it was recently introduced with potting soil (from South or Central America?) or was mislabelled or transported with the collecting equipment.

description: A motion planning methodology based on the combination of Control Barrier Functions (CBF) and Signal Temporal Logic (STL) is employed in this paper. This methodology allows task completion at any point within a specified time interval, considering a dynamic system subject to velocity constraints. In this work, we apply this approach into the context of Socially Responsible Navigation (SRN), introducing a rotation constraint. This constraint is designed to maintain the user within the robot's field of view (FOV), enhancing human-robot interaction with the concept of side-by-side human-robot companion. This angular constraint offers the possibility to customize social navigation to specific needs, thereby enabling safe SRN. Its validation is carried out through simulations demonstrating the system's effectiveness in adhering to spatio-temporal constraints, including those related to robot velocity, rotation, and the presence of static and dynamic obstacles.

description: The diffraction of stochastic point sets, both Bernoulli and Markov, and of random tilings with crystallographic symmetries is investigated in rigorous terms. In particular, we derive the diffraction spectrum of 1D random tilings, of stochastic product tilings built from cuboids, and of planar random tilings based on solvable dimer models, augmented by a brief outline of the diffraction from the classical 2D Ising lattice gas. We also give a summary of the measure theoretic approach to mathematical diffraction theory which underlies the unique decomposition of the diffraction spectrum into its pure point, singular continuous and absolutely continuous parts.

description: This thesis explores different aspects of a surprising field of research: the conformally invariant scaling limits of planar statistical mechanics models.
      The aspects developed here include the proof of convergence of certain interfaces in the critical Ising magnetization model (joint work with Hugo Duminil-Copin and Clement Hongler), a study of the near-critical behavior of the uniform spanning tree in the scaling limit (joint work with Laure Dumaz and Wendelin Werner), the construction of an interesting measure on continuous loops satisfying a certain stability property under deformation (joint work with Julien Dubedat) as well as some related algebraic considerations, and finally, notes on a paper of Sheffield, that studies a certain coupling of the scaling limits of discrete interfaces - SLE curves - together with random surfaces obtained from the Gaussian free field.

description: We demonstrate that the structure of complex second-order strongly elliptic operators $H$ on ${\bf R}^d$ with coefficients invariant under translation by ${\bf Z}^d$ can be analyzed through decomposition in terms of versions $H_z$, $z\in{\bf T}^d$, of $H$ with $z$-periodic boundary conditions acting on $L_2({\bf I}^d)$ where ${\bf I}=[0,1>$. If the semigroup $S$ generated by $H$ has a Hölder continuous integral kernel satisfying Gaussian bounds then the semigroups $S^z$ generated by the $H_z$ have kernels with similar properties and $z\mapsto S^z$ extends to a function on ${\bf C}^d\setminus\{0\}$ which is analytic with respect to the trace norm. The sequence of semigroups $S^{(m),z}$ obtained by rescaling the coefficients of $H_z$ by $c(x)\to c(mx)$ converges in trace norm to the semigroup $\hat{S}^z$ generated by the homogenization $\hat{H}_z$ of $H_z$. These convergence properties allow asymptotic analysis of the spectrum of $H$.

description: Introduction: Beyond participation in evaluation of teaching, there is sparse research available on more active roles of medical students in curriculum development. We report on a model of student engagement where medical students function as module co-directors, and how this is experienced by faculty and student module directors. Methods: Student engage in co-development of their curriculum with a high level of autonomy in organizing their activities. We conducted a mixed-methods, convergent design study based on surveys with faculty and student module co-directors and a student co-director focus group. Quantitative data were analyzed descriptively. Qualitative analysis was performed inductively. Results: Quantitatively, the majority of both faculty and student module directors report that the curriculum benefits from the students’ work (95 and 94%). Both groups see each other as equal partners (80 and 87%). Qualitatively, this is related to students’ competencies such as “bringing in broad and unique knowledge of the curriculum”, “giving the students’ perspective a voice,” and “contributing ideas for improvement”. Key strategies and challenges of the student co-module directors are illuminated. Conclusions: Student module co-directors represent a well-accepted practice model for curriculum development. This report may stimulate other faculties to engage their students more actively in medical education.

description: Encoding quantum information in continuous variables is intrinsically faulty. Nevertheless, redundant qubits can be used for error correction, as proposed by Gottesman, Kitaev and Preskill in Phys. Rev. A \textbf{64} 012310, (2001). We show how to experimentally implement this encoding using time-frequency continuous degrees of freedom of photon pairs produced by spontaneous parametric down conversion. We experimentally illustrate our results using an integrated AlGaAs photon pairs source. We show how single qubit gates can be implemented and finally propose a theoretical scheme for correcting errors in a circuit-like and in a measurement-based architecture.
CBF-Based Motion Planning for Socially Responsible Robot Navigation Guaranteeing STL Specification

description: In the field of control engineering, the connection between Signal Temporal Logic (STL) and time-varying Control Barrier Functions (CBF) has attracted considerable attention. CBFs have demonstrated notable success in ensuring the safety of critical applications by imposing constraints on system states, while STL allows for precisely specifying spatio-temporal constraints on the behavior of robotic systems. Leveraging these methodologies, this paper addresses the safety-critical navigation problem, in Socially Responsible Navigation (SRN) context, presenting a CBF-based STL motion planning methodology. This methodology enables task completion at any time within a specified time interval considering a dynamic system subject to velocity constraints. The proposed approach involves real-time computation of a smooth CBF, with the computation of a dynamically adjusted parameter based on the available path space and the maximum allowable velocity. A simulation study is conducted to validate the methodology, ensuring safety in the presence of static and dynamic obstacles and demonstrating its compliance with spatio-temporal constraints under non-linear velocity constraints.

description: The reconstruction of gene regulatory networks is one of the milestones of computational system biology. We introduce a new implementation of ARACNe (Algorithm for the Reconstruction of Accurate Cellular Networks) to reverse engineer transcriptional regulatory networks with improved mutual information estimators and significant improvement in performance. In the context of data driven network inference we identify two major confounding biases and introduce solutions to remove some of the discussed biases. First we identify prevalent spatial biases in gene expression studies derived from plate based designs. We investigate the gene expression profiles of a million samples from the LINCS dataset and find that the vast majority (96%) of the tested plates is affected by significant spatial bias. We can show that our proposed method to correct these biases results in a significant improvement of similarity between biological replicates assayed in different plates. Lastly we discuss the effect of CNV on gene expression and its confounding effect on the correlation landscape of genes in the context of cancer samples. We propose a method that removes the variance in gene expression explained by CNV and show that TF target predictions can be significantly improved.
Loop Quantum Gravity and Ultra High Energy Cosmic Rays
Creators: name: Alfaro, Jorge

Publisher: name: arXiv

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: There are two main sets of data for the observed spectrum of ultra high energy cosmic rays (those cosmic rays with energies greater than $\sim 4 \times 10^{18}$ eV), the High Resolution Fly's Eye (HiRes) collaboration group observations, which seem to be consistent with the predicted theoretical spectrum (and therefore with the theoretical limit known as the Greisen-Zatsepin-Kuzmin cutoff), and the observations from the Akeno Giant Air Shower Array (AGASA) collaboration group, which reveal an abundant flux of incoming particles with energies above $1 \times 10^{20}$ eV violating the Greisen-Zatsepin-Kuzmin cutoff. As an explanation of this anomaly it has been suggested that quantum-gravitational effects may be playing a decisive role in the propagation of ultra high energy cosmic rays. In this article we take the loop quantum gravity approach. We shall provide some techniques to establish and analyze new constraints on the loop quantum gravity parameters arising from both sets of data, HiRes and AGASA . We shall also study their effects on the predicted spectrum for ultra high energy cosmic rays. As a result we will state the possibility of reconciling the AGASA observations.

description: Political scientists have long been interested in the rationale behind giving official development assistance (ODA). With a few notable exceptions, scholars have neglected the impact of governing parties of differ-ent provenience on a donor country’s foreign aid policy. In order to address this shortcoming, this paper focuses on the change of government from conservative (‚right‘) to social democratic (‚left‘) parties in Sweden (1994) and the United Kingdom (1997). The results contradict and qualify much of the conven-tional wisdom on the allegedly more benign foreign aid policy of social democratic parties. The paper reveals instead that the Swedish and British foreign aid policies of the 1990s share an interesting pattern: Social democrats tend to display a rhetoric that is more attuned to the idea of solidarity than the conserva-tive foreign aid agenda, but in neither case does this tendency translate into a higher degree of solidarity as measured by five quantitative measures. On the contrary, conservative ODA actions speak louder than their words suggest, expressing at least as much, if not more, solidarity than their social democratic rivals.

description: Aim: Many factors affect learning outcomes, however studies comparing the effectiveness of different clinical teaching methods are limited. We utilize the list of influences on educational achievement compiled by John Hattie to inform a meta-analysis of learning effect sizes (ESs) associated with teaching-learning factors (TLFs) in clinical education. Methods: A literature search was conducted in PubMed to identify articles examining clinically relevant TLFs. Selection criteria were applied to identify learner-focused studies, with subsequent categorization by study design (pretest–posttest or controlled group). The Cohen’s ES (d) for each TLF was extracted and a pooled ES determined. Results: From 3454 studies, 132 suitable articles enabled analysis of 16 TLFs’ ESs. In general, ESs derived from pretest–posttest data were larger than those from controlled group designs, probably due to learner maturation effect. The TLFs of mastery learning, small group learning and goal settings possessed the largest ESs (d ≥ 0.8), while worked examples, play programs, questioning, concept mapping, meta-cognitive strategies, visual-perception programs and teaching strategies demonstrated ESs between 0.4 and 0.8. Conclusions: This is the first study to provide a rigorous and comprehensive overview of the effectiveness of TLFs in clinical education. We discuss the practical traits shared by effective TLFs which may assist teaching design.

description: Systems Engineering is a diverse field both in terms of approaches but also in impact and exploitation. Working across 12 political systems, with over 700 aircraft operational worldwide, the F-35 is a 5th Generation military aircraft which delivers impact through data. Keeping all the software intensive systems flying, through obsolescence, repair, new technology and upgrade is a configuration and logistical challenge. In late 2019, the US F-35 Joint Project Office embraced agile software delivery to reduce software cycle times from 18 months to 6 weeks. This is the story of that time.
