description: We consider 1-D quasi-periodic Frenkel-Kontorova models. We study the existence of equilibria whose frequency (i.e. the inverse of the density of deposited material) is resonant with the frequencies of the substratum. We study perturbation theory for small potential. We show that there are perturbative expansions to all orders for the quasi-periodic equilibria with resonant frequencies. Under very general conditions, we show that there are at least two such perturbative expansions for equilibria for small values of the parameter. We also develop a dynamical interpretation of the equilibria in these quasi-periodic media. We show that equilibria are orbits of a dynamical system which has very unusual properties. We obtain results on the Lyapunov exponents of the dynamical systems, i.e. the phonon gap of the resonant quasi-periodic equilibria. We show that the equilibria can be pinned even if the gap is zero.

description: Many studies have focused on the interactive effects of temperature increases due to global warming and nutrient enrichment on phytoplankton communities. Recently, non-temperature effects of climate change (e.g., decreases in wind speed and increases in solar radiation) on large lakes have received increasing attention. To evaluate the relative contributions of both temperature and non-temperature effects on phytoplankton communities in a large eutrophic subtropical shallow lake, we analyzed long-term monitoring data from Lake Taihu, China from 1997 to 2016. Results showed that Lake Taihu's spring phytoplankton biovolume and composition changed dramatically over this time frame, with a change in dominant species. Stepwise multiple linear regression models indicated that spring phytoplankton biovolume was strongly influenced by total phosphorus (TP), light condition, wind speed and total nitrogen (TN) (radj 2= 0.8, p < 0.01). Partial redundancy analysis (pRDA) showed that light condition accounted for the greatest variation of phytoplankton community composition, followed by TP and wind speed, as well as the interactions between TP and wind speed. Our study points to the additional importance of non-temperature effects of climate change on phytoplankton community dynamics in Lake Taihu.

description: We discuss the $\sqrt{s}$-dependence of the $K^+/π^+$ ratio in heavy-ion collisions (the "horn" effect) within a Mott-Anderson localization model for chemical freeze-out. The different response of pion and kaon radii to the hot and dense hadronic medium results in different freeze-out conditions. We demonstrate within a simple model that this circumstance enhances the "horn" effect relative to statistical models with universal chemical freeze-out.

description: Internet-of-Things (IoT) has widely permeated our daily lives and is used for various applications ranging from agriculture to industrial IoT. Recent years have seen the emergence of Low-Power Wide-Area Networks (LP-WANs) as a promising technology to connect the Internet of Things. LP-WAN technologies allow devices to send data at low data rate (few kbps) to base stations several miles away while lasting 5-10 years powered by batteries. These LP-WAN deployments are inherently asymmetric where more resourceful base stations and cloud infrastructure lie on the other side of the clients’ bandwidth starved link. This precludes the possibility of data-driven applications on LP-WAN deployments for large scale sensing such as smart agriculture, automated traffic signals and micro-climate monitoring. While most smart-home sensors can communicate large amounts of data to enable low-latency complex inference applications, the big data revolution has eluded such outdoor sensors from realizing their true potential. This thesis overcomes fundamental limitations of such low-power wireless technologies and builds systems that enable such data driven applications at scale. Firstly, we develop solutions that can push the wireless and compute operations from these low-power IoT clients to the much more powerful base stations. We further take a cross-layer approach to enable data-driven applications on these IoT sensors at scale by co-optimizing their wireless physical layer to improve client range and throughput while reducing latency for higher level network and inference objectives. My solutions apply these principles for improving LoRa, a popular LP-WAN technology, where this asymmetry is particularly stark. First, we enable base station collaboration which allows us to push components of the LoRa physical layer from the clients to the base stations and the shared cloud infrastructure. This collaboration allows us to reduce power expenditure at clients while improving communication range as well as throughput. Further, this collaborative base station framework can also enable decameter-level location tracking. Next, we develop a distributed LP-WAN physical layer that can perform complex low-latency statistical, spatial and inference queries on thousands of low-power clients. Finally, we show how we can empower LoRa-enabled CubeSats deployed in low-earth orbit by co-designing higher level data-driven applications within communication constraints for multi-fold improvement in inference and data retrieval quality.

description: We consider a two-dimensional layer of dipolar particles in the regime of strong dipole moments. Here we can describe the system using classical methods and determine the crystal structure that minimizes the total energy. The dipoles are assumed to be aligned by an external field and we consider different orientations of the dipolar moments with respect to the two-dimensional plane of motion. We observe that when the orientation angle changes away from perpendicular and towards the plane, the crystal structure will change from a hexagonal form to one that has the dipoles sitting in equidistant rows, i.e. a striped configuration. In addition to calculating the crystal unit cell, we also consider the phonon spectrum and the speed of sound. As the orientation changes away from perpendicular the phonon spectrum develops local minima that are a result of the deformation to the crystal structure.

description: Interactions with neutrons and protons play a crucial role for the neutrino opacity of matter in the supernova core. Their current implementation in many simulation codes, however, is rather schematic and ignores not only modifications for the correlated nuclear medium of the nascent neutron star, but also free-space corrections from nucleon recoil, weak magnetism or strange quarks, which can easily add up to changes of several 10% for neutrino energies in the spectral peak. In the Garching supernova simulations with the Prometheus-Vertex code, such sophistications have been included for a long time except for the strange-quark contributions to the nucleon spin, which affect neutral-current neutrino scattering. We demonstrate on the basis of a 20 M_sun progenitor star that a moderate strangeness-dependent contribution of g_a^s = -0.2 to the axial-vector coupling constant g_a = 1.26 can turn an unsuccessful three-dimensional (3D) model into a successful explosion. Such a modification is in the direction of current experimental results and reduces the neutral-current scattering opacity of neutrons, which dominate in the medium around and above the neutrinosphere. This leads to increased luminosities and mean energies of all neutrino species and strengthens the neutrino-energy deposition in the heating layer. Higher nonradial kinetic energy in the gain layer signals enhanced buoyancy activity that enables the onset of the explosion at ~300 ms after bounce, in contrast to the model with vanishing strangeness contributions to neutrino-nucleon scattering. Our results demonstrate the close proximity to explosion of the previously published, unsuccessful 3D models of the Garching group.

description: Cyanobacteria can form dense and sometimes toxic blooms in freshwater and marine environments, which threaten ecosystem functioning and degrade water quality for recreation, drinking water, fisheries and human health. Here, we review evidence indicating that cyanobacterial blooms are increasing in frequency, magnitude and duration globally. We highlight species traits and environmental conditions that enable cyanobacteria to thrive and explain why eutrophication and climate change catalyse the global expansion of cyanobacterial blooms. Finally, we discuss management strategies, including nutrient load reductions, changes in hydrodynamics and chemical and biological controls, that can help to prevent or mitigate the proliferation of cyanobacterial blooms.
Rotational self-diffusion in suspensions of charged particles: Revised Beenakker-Mazur and Pairwise Additivity methods versus numerical simulations

description: To the present day, the Beenakker-Mazur (BM) method is the most comprehensive statistical physics approach to the calculation of short-time transport properties of colloidal suspensions. A revised version of the BM method with an improved treatment of hydrodynamic interactions is presented and evaluated regarding the rotational short-time self-diffusion coefficient, $D^r$ , of suspensions of charged particles interacting by a hard-sphere plus screened Coulomb (Yukawa) pair potential. To assess the accuracy of the method, elaborate simulations of $D^r$ have been performed, covering a broad range of interaction parameters and particle concentrations. The revised BM method is compared in addition with results by a simplifying pairwise additivity (PA) method in which the hydrodynamic interactions are treated on a two-body level. The static pair correlation functions re- quired as input to both theoretical methods are calculated using the Rogers-Young integral equation scheme. While the revised BM method reproduces the general trends of the simulation results, it systematically and significantly underestimates the rotational diffusion coefficient. The PA method agrees well with the simulation data at lower volume fractions, but at higher concentrations $D^r$ is likewise underestimated. For a fixed value of the pair potential at mean particle distance comparable to the thermal energy, $D^r$ increases strongly with increasing Yukawa potential screening parameter.

description: Particle methods are a ubiquitous tool for solving the Vlasov-Poisson equation in comoving coordinates, which is used to model the gravitational evolution of dark matter in an expanding universe. However, these methods are known to produce poor results on idealized test problems, particularly at late times, after the particle trajectories have crossed. To investigate this, we have performed a series of one- and two-dimensional "Zel'dovich Pancake" calculations using the popular Particle-in-Cell (PIC) method. We find that PIC can indeed converge on these problems provided the following modifications are made. The first modification is to regularize the singular initial distribution function by introducing a small but finite artificial velocity dispersion. This process is analogous to artificial viscosity in compressible gas dynamics, and, as with artificial viscosity, the amount of regularization can be tailored so that its effect outside of a well-defined region - in this case, the high-density caustics - is small. The second modification is the introduction of a particle remapping procedure that periodically re-expresses the dark matter distribution function using a new set of particles. We describe a remapping algorithm that is third-order accurate and adaptive in phase space. This procedure prevents the accumulation of numerical errors in integrating the particle trajectories from growing large enough to significantly degrade the solution. Once both of these changes are made, PIC converges at second order on the Zel'dovich Pancake problem, even at late times, after many caustics have formed. Furthermore, the resulting scheme does not suffer from the unphysical, small-scale "clumping" phenomenon known to occur on the Pancake problem when the perturbation wave vector is not aligned with one of the Cartesian coordinate axes.

description: Cyber-physical systems (CPSs), engineered systems which include sensing, processing, control, and communication in physical spaces, are ubiquitous in modern critical infrastructures including manufacturing, transportation systems, energy delivery, health care, water management, and the smart grid. The presence of heterogeneous components and devices creates numerous attack surfaces in these large scale, highly connected systems. Consequently, these systems are attractive targets for adversaries and are essential to protect in today’s society. In this dissertation, we provide a set of mechanisms and tools that can be used to achieve resilient CPSs, where safety is preserved while functionality is restored in the presence of attacks. More specifically, we focus on two necessary components in designing resilient CPSs: detection and response. The recognition and detection of attacks is the first and foremost step in achieving resilience. Once an attack is detected, a number of forms of active response can be implemented to ensure system resilience. We first present a number of tools which leverage both cyber theory and system theory to detect powerful stealthy attacks. Specifically, we set forth the moving target defense as an active detection mechanism for detecting what would otherwise be stealthy covert attacks. We then introduce a number of response mechanisms which leverage both cyber theory and system theory to ensure safety and security against these attacks. Specifically, we set forth software rejuvenation and overlay networks as response mechanisms that provide resilience against attacks on the CPS control software and communication network, respectively. We then set forth some general design and analysis tools for achieving resilient CPSs, providing a framework that minimizes an adversary’s window of opportunity when attacking decentralized systems. We conclude by providing a general tool that analyzes the resilience of any response mechanism against stealthy attacks.

description: We present an investigation of twelve candidate transiting planets from Kepler with orbital periods ranging from 34 to 207 days, selected from initial indications that they are small and potentially in the habitable zone (HZ) of their parent stars. Few of these objects are known. The expected Doppler signals are too small to confirm them by demonstrating that their masses are in the planetary regime. Here we verify their planetary nature by validating them statistically using the BLENDER technique, which simulates large numbers of false positives and compares the resulting light curves with the Kepler photometry. This analysis was supplemented with new follow-up observations (high-resolution optical and near-infrared spectroscopy, adaptive optics imaging, and speckle interferometry), as well as an analysis of the flux centroids. For eleven of them (KOI-0571.05, 1422.04, 1422.05, 2529.02, 3255.01, 3284.01, 4005.01, 4087.01, 4622.01, 4742.01, and 4745.01) we show that the likelihood they are true planets is far greater than that of a false positive, to a confidence level of 99.73% (3 sigma) or higher. For KOI-4427.01 the confidence level is about 99.2% (2.6 sigma). With our accurate characterization of the GKM host stars, the derived planetary radii range from 1.1 to 2.7 R_Earth. All twelve objects are confirmed to be in the HZ, and nine are small enough to be rocky. Excluding three of them that have been previously validated by others, our study doubles the number of known rocky planets in the HZ. KOI-3284.01 (Kepler-438b) and KOI-4742.01 (Kepler-442b) are the planets most similar to the Earth discovered to date when considering their size and incident flux jointly.

description: A severe cyanobacterial bloom in the mainstem of a large Chinese river was first reported from China. The Qiantang River is the longest river in the Zhejiang province, southeast China. It provides drinking water supply to ~ 16 million people, including Hangzhou city. Fifteen sites along the Qiantang River (including upper, middle (Fuchunjiang Reservoir), and lower reaches and tributaries) were sampled between August 13 and September 9, 2016 to conduct a preliminary examination of the outbreak of Microcystis blooms. Laboratory investigation revealed that Microcystis spp. are dominant in the Fuchunjiang Reservoir (an overflow reservoir on the mainstem of the Qiantang River) with an extremely high cell density of 2.3 × 108 cells/L, leading to a severe bloom in the mainstem of the Qiantang River. Investigations of the meteorological, hydrological, and nutrient characteristics associated with the bloom indicated that extremely dry (6.8 mm rainfall from August 13 to September 9, 2016) and hot (32 consecutive days of temperatures > 30 °C from July 20 to August 31, 2016) weather might be the key factors triggering the bloom. Additionally, the extremely low flow of the tributary, Lanjiang River (142 ± 56 m3/s from August 13 to September 9), and its high nutrient background, favored the bloom. While nutrient reductions are important, the most immediate and effective management approach might be to implement appropriate minimal flow conditions to mitigate the blooms.

description: Quillen proved that, if a Hermitian bihomogeneous polynomial is strictly positive on the unit sphere, then repeated multiplication of the standard sesquilinear form to this polynomial eventually results in a sum of Hermitian squares. Catlin-D'Angelo and Varolin deduced this positivstellensatz of Quillen from the eventual positive-definiteness of an associated integral operator. Their arguments involve asymptotic expansions of the Bergman kernel. The goal of this article is to give an elementary proof of the positive-definiteness of this integral operator.

El estudio de la desinformación es de por sí un desafío, al ser un problema polimórfico, de factores múltiples y que no tiene una única forma de ser solucionado, según la Comisión Europea. En lo que se refiere a España, no deja de ser un tema relevante y de creciente preocupación social. Algo que ha contribuido al surgimiento de acciones orientadas a la verificación de contenidos desinformativos divulgados en contextos digitales (ejemplo: Servimedia y 16 medios de comunicación españoles han lanzado recientemente la iniciativa denominada «Comprobado» para la verificación de contenido relacionado con las elecciones del 28 de abril de 2019), así como al estudio del fenómeno. Medidas que deben ser estudiadas y analizadas desde las particularidades culturales y lingüísticas del castellano y de los rasgos que caracterizan a la sociedad española. Este trabajo se centra en abordar lo antes expuesto, desde los resultados generales obtenidos durante el año 1 del proyecto que se está ejecutando desde la Universidad Internacional de la Rioja desde septiembre de 2019. Un proyecto que pretende ahondar en la comprensión del panorama de la desinformación en contextos digitales promovido por y desde actores políticos en España, desde la implementación de perspectivas metodológicas cuali-cuantitivas, las cuales han permitido avanzar en la identificación de la frontera de conocimiento científico en esta temática y otros resultados considerados de interés de la comunidad científica.

description: Fermi-LAT analyses show that the gamma-ray photon spectral indices Gamma_gamma of a large sample of blazars correlate with the vFv peak synchrotron frequency v_s according to the relation Gamma_gamma = d - k log v_s. The same function, with different constants d and k, also describes the relationship between Gamma_gamma and peak Compton frequency v_C. This behavior is derived analytically using an equipartition blazar model with a log-parabola description of the electron energy distribution (EED). In the Thomson regime, k = k_EC = 3b/4 for external Compton processes and k = k_SSC = 9b/16 for synchrotron self-Compton (SSC) processes, where b is the log-parabola width parameter of the EED. The BL Lac object Mrk 501 is fit with a synchrotron/SSC model given by the log-parabola EED, and is best fit away from equipartition. Corrections are made to the spectral-index diagrams for a low-energy power-law EED and departures from equipartition, as constrained by absolute jet power. Analytic expressions are compared with numerical values derived from self-Compton and external Compton scattered gamma-ray spectra from Ly alpha broad-line region and IR target photons. The Gamma_gamma vs. v_s behavior in the model depends strongly on b, with progressively and predictably weaker dependences on gamma-ray detection range, variability time, and isotropic gamma-ray luminosity. Implications for blazar unification and blazars as ultra-high energy cosmic-ray sources are presented. Arguments by Ghisellini et al. (2014) that the jet power exceeds the accretion luminosity depend on the doubtful assumption that we are viewing at the Doppler angle.

Why does N-limitation persist in the world's marine waters?
Creators: name: Paerl, H.W.
Publisher: name: Elsevier B.V.
Year: 2018

description: Primary production of vast regions of the world's estuarine, coastal and pelagic ocean waters is limited by availability of fixed nitrogen; this despite the fact that a highly diverse suite of microorganisms potentially capable of fixing N2 (eubacteria and cyanobacteria), inhabit these waters. Theoretically, diazotrophs should supply the N needs to balance the N required to support primary production, assuming other key limiting nutrients, phosphorus and iron, are available and energy requirements are met. In practice however, N2 fixation often does not meet ecosystem-scale N demands, even when these nutrients are replete. The problem lies with the fact that optimal rates of N2 fixation are often controlled by additional environmental factors, including light and organic matter availability, turbulence, and high levels of dissolved oxygen which can suppress this process in N-deplete surface waters. In addition, rates of N loss via denitrification and anammox can exceed N2 fixation and external N inputs on annual scales in coastal and pelagic waters, including those experiencing eutrophication. This creates a situation where chronic N limitation persists, even in the presence of anthropogenic nitrogen enrichment. Many aquatic ecosystems exhibit a perpetual “hunger” for fixed N to support primary and higher levels of production and this is likely to continue over forseeable biological and geologic timescales.

description: We propose a semiclassical method to calculate S-matrix elements for two-stage gravitational transitions involving matter collapse into a black hole and evaporation of the latter. The method consistently incorporates back-reaction of the collapsing and emitted quanta on the metric. We illustrate the method in several toy models describing spherical self-gravitating shells in asymptotically flat and AdS space-times. We find that electrically neutral shells reflect via the above collapse-evaporation process with probability exp(-B), where B is the Bekenstein-Hawking entropy of the intermediate black hole. This is consistent with interpretation of exp(B) as the number of black hole states. The same expression for the probability is obtained in the case of charged shells if one takes into account instability of the Cauchy horizon of the intermediate Reissner-Nordstrom black hole. Our semiclassical method opens a new systematic approach to the gravitational S-matrix in the non-perturbative regime.

description: So far, only one rotating disk has been clearly identified and studied in AGB or post-AGB objects (in the Red Rectangle), by means of observations with high spectral and spatial resolution. However, disks are thought to play a key role in the late stellar evolution and are suspected to surround many evolved stars. We aim to extend our knowledge on these structures. We present interferometric observations of CO J=2-1 emission from the nebula surrounding the post-AGB star AC Her, a source belonging to a class of objects that share properties with the Red Rectangle and show hints of Keplerian disks. We clearly detect the Keplerian dynamics of a second disk orbiting an evolved star. Its main properties (size, temperature, central mass) are derived from direct interpretation of the data and model fitting. With this we confirm that there are disks orbiting the stars of this relatively wide class of post-AGB objects

title: A systematic review of CEO duality and firm performance in different organizational contexts
Creators: name: Baliyarsingh, Utkal Kumar
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: CEO duality is a situation that emerges when the Chief Executive Officer (CEO) also serves as the Chair of the Board of Directors. In absence of CEO duality, the board is considered independent. CEO duality as an issue is of utmost importance in the field of corporate governance and corporate strategy. From its scholarly inception in the early 1990s this phenomenon has become more complex with contradicting and mixed results, which is evident from the extant literature. The inconclusive nature of the debate prompts researchers to look beyond a direct link between CEO duality and Firm performance. To understand the nature of this phenomenon, a systematic literature review was conducted uncovering 62 research articles over a period of almost two decades. First of all, the review suggests that given its broad and multidisciplinary relevance, the current form of literature on CEO duality needs more organization. Second, the study identifies key research areas in which CEO duality was studied. Findings show that, although, CEO duality does not, on its own, improve or reduce firm performance, the performance implications of CEO duality could be dependent on various other firm specific parameters, which corporate boards need to acknowledge. Finally, this study discusses identified themes and highlights the need for a multi-level analysis followed by future research directions, management implications, and a limitation section.
On relation between rest frame and light-front descriptions of quarkonium

description: In this paper we study the relation between the light-front (infinite momentum) and rest-frame descriptions of quarkonia. While the former is more convenient for high-energy production, the latter is usually used for the evaluation of charmonium properties. In particular, we discuss the dynamics of a relativistically moving system with nonrelativistic internal motion and give relations between rest frame and light-front potentials used for the description of quarkonium states. We consider two approximations, first the small coupling regime, and next the nonperturbative small binding energy approximation. In both cases we get consistent results. Our results could be relevant for the description of final state interactions in a wide class of processes, including quarkonium production on nuclei and plasma. Moreover, they can be extended to the description of final state interactions in the production of weakly bound systems, such as for example the deuteron.

description: We have explored Natural Supersymmetry (NSUSY) scenarios with low values of the $μ$ parameter which are characterised by higgsino-like Dark Matter (DM) and compressed spectra for the lightest MSSM particles, $χ^0_1$, $χ^0_2$ and $χ^\pm_1$. This scenario could be probed via monojet signatures, but as the signal-to-background ratio (S/B) is low we demonstrate that the 8 TeV LHC cannot obtain limits on the DM mass beyond those of LEP2. On the other hand, we have found, for the 13 TeV run of the LHC, that by optimising kinematical cuts we can bring the S/B ratio up to the 5(3)% level which would allow the exclusion of the DM mass up to 200(250) GeV respectively, significantly extending LEP2 limits. Moreover, we have found that LUX/XENON1T and LHC do play very complementary roles in exploring the parameter space of NSUSY, as the LHC has the capability to access regions where DM is quasi-degenerate with other higgsinos, which are challenging for direct detection experiments.

description: The Upper Triassic tetrapod fossil record of North America features a pronounced discrepancy between the assemblages of present-day Virginia and North Carolina relative to those of the American Southwest. While both are typified by large-bodied archosaurian reptiles like phytosaurs and aetosaurs, the latter notably lacks substantial representation of mammal relatives, including cynodonts. Recently collected non-mammalian eucynodontian jaws from the Middle Norian Blue Mesa Member of the Chinle Formation in northeastern Arizona shed light on the Triassic cynodont record from western equatorial Pangaea. Importantly, they reveal new biogeographic connections to eastern equatorial Pangaea as well as southern portions of the supercontinent. This discovery indicates that the faunal dissimilarity previously recognized between the western and eastern portions of equatorial Pangaea is overstated and possibly reflects longstanding sampling biases, rather than a true biogeographic pattern.
Non-Metallic Inclusion Generation and Evolution in Specialty Steelmaking Processes
Creators: name: Huck, Andrew
Publisher: name: Carnegie Mellon University
Year: 2023
Subjects: Thermodynamics

description: In this study, inclusion evolution and slag/metal reactions were examined in various specialty steelmaking processes. Particular focus was paid to the differential processing conditions and compositions that are present in specialty steels, as these were expected to impact inclusion generation and evolution significantly compared to the more oft studied ladle and continuous casting processes. A number of separate studies were undertaken in the following areas: AOD and ladle treatment, IF experiments, vacuum metallurgy, electro-slag remelting, and boron nitride formation in the solid state. For AOD and ladle work, it was hypothesized that a one parameter EERZ model could simulate inclusion evolution in both vessels, which was partially supported. Additionally, the Mg*O associate was hypothesized to inaccurately model thermodynamic behavior at high temperatures, which was validated by analysis of AOD data and later by induction furnace experiments. For vacuum metallurgy, calcium was revealed to be a potential source of issues as a result of slowing down the kinetics of carbothermic reduction, which was the primary inclusion removal mechanism. In ESR, the loss of deoxidants and formation of manganese silicate inclusions was revealed to almost certainly be the result of oxidation at high temperatures of the process electrode in atmosphere. Finally, boron nitride formation was found to occur in the solid state under specific composition and temperature conditions.
Global Phase Diagram of Competing Ordered and Quantum Spin Liquid Phases on the Kagomé Lattice

description: We study the quantum phase diagram of the spin-$1/2$ Heisenberg model on the kagomé lattice with first-, second-, and third-neighbor interactions $J_1$, $J_2$, and $J_3$ by means of density matrix renormalization group. For small $J_2$ and $J_3$, this model sustains a time-reversal invariant quantum spin liquid phase. With increasing $J_2$ and $J_3$, we find in addition a $q=(0,0)$ Néel phase, a chiral spin liquid phase, a valence-bond crystal phase, and a complex non-coplanar magnetically ordered state with spins forming the vertices of a cuboctahedron known as a cuboc1 phase. Both the chiral spin liquid and cuboc1 phase break time reversal symmetry in the sense of spontaneous scalar spin chirality. We show that the chiralities in the chiral spin liquid and cuboc1 are distinct, and that these two states are separated by a strong first order phase transition. The transitions from the chiral spin liquid to both the $q=(0,0)$ phase and to time-reversal symmetric spin liquid, however, are consistent with continuous quantum phase transitions.
