description: Majorana features of neutrinos and SO(3) gauge symmetry of three families enable us to construct a gauge model of neutrino for understanding naturally the observed smallness of neutrino masses and the nearly tri-bimaximal neutrino mixing when combining together with the mechanism of approximate global U(1) family symmetry. The vacuum structure of SO(3) symmetry breaking is found to play an important role. The mixing angle $θ_{13}$ and CP-violating phases governed by the vacuum of spontaneous symmetry breaking are in general non-zero and testable experimentally at the allowed sensitivity. The model predicts the existence of vector-like SO(3) triplet charged leptons and vector-like SO(3) triplet Majorana neutrinos as well as SO(3) tri-triplet Higgs bosons, some of them can be light and explored at the colliders LHC and ILC.

description: We study general aspects of active motion with fluctuations in the speed and the direction of motion in two dimensions. We consider the case in which fluctuations in the speed are not correlated to fluctuations in the direction of motion, and assume that both processes can be described by independent characteristic time-scales. We show the occurrence of a complex transient that can exhibit a series of alternating regimes of motion, for two different angular dynamics which correspond to persistent and directed random walks. We also show additive corrections to the diffusion coefficient. The characteristic time-scales are also exposed in the velocity autocorrelation, which is a sum of exponential forms.

description: Wētā (Orthoptera: Anostostomatidae) are a well-recognised component of New Zealand nocturnal ecology, but much of the diversity remains undescribed and only partly characterised. Species of Hemiandrus conceal themselves during the day in soil burrows and most are infrequently encountered, however, one taxon is notorious in some South Island vineyards. We demonstrate that this wētā at unusually high density in some vineyards in the Awatere valley is also found in North Island forests (Hemiandrus bilobatus). Here we use morphological and genetic data to identify the wine wētā and examine its ecology in vineyards. We also describe four new species which belong to the same ground wētā clade as the wine wētā. We provide mtDNA analysis and diagnostic morphological characters to distinguish six Hemiandrus species that are characterised by adult females having an extremely short ovipositor and maternal care.
Examining the Limitations of Representational Competence to Investigate Conceptual Change in Chemistry
Creators: name: Spurgeon, Sidney Gates
Publisher: name: University of Illinois at Chicago
Year: 2024

description: This thesis identifies and explains the gaps in prior and current applications of representational competence construct in chemistry. Representational competence (RC) describes a set of skills that chemistry researchers Kozma and Russell observed experts demonstrate when engaging with disciplinary representations (Kozma & Russell, 1997; Kozma & Russell, 2005). These skills have commonly been used as a frame for other researchers to study student engagement with disciplinary representations and to design instructional practices to improve novice skill development.
Development of a Framework and Checklist to Guide the Translation of AI Systems for Clinical Care
Creators: name: Owoyemi, Ayomide Joseph
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Implementing AI systems in a clinical setting requires adequate consideration of the social aspects of its application alongside the technical ones. It is essential to understand the context in which the technology will be used, how it will work with existing workflows without disruption, and how it will be accepted by the people who will have to use it. Despite the numerous proof-of-concept publications in this field, the lack of robust frameworks for supporting these tools' design, development, and management is one of the main barriers to their adoption in healthcare. This study employs primary research using a mixed methods approach to investigate the factors influencing the implementation and effectiveness of the Epic Sepsis System at UI Health and the experiences of clinicians with the same tool. It combines this with the results of a literature review to create a framework. A Delphi study was conducted to expand the framework into a checklist, which was validated through interviews with purposively selected members of the UI Health Diabetes Tool development team. Findings from this study show that the successful implementation and integration of AI in a clinical setting depends on a balanced focus on the clinical settings' technical and social dynamics. Also identified were critical gaps in existing frameworks primarily focused on technical specifications or ethics, neglecting the comprehensive sociotechnical dynamics essential for developing and implementing AI systems in clinical environments. Clinical AI Sociotechnical Framework (CASoF) addresses this gap by providing a framework and a structured checklist that guides the planning, design, development, and implementation stages of AI systems in clinical settings. The checklist emphasizes the importance of considering the value proposition, data integrity, human-AI interaction, technical architecture, organizational culture, and ongoing support and monitoring, ensuring that AI tools are technologically sound, practically viable, and socially adaptable within clinical settings. CASoF represents a step forward in bridging this divide, offering a holistic approach to AI deployment that is mindful of the complexities of healthcare systems.
Existence and properties of geometric quotients

Subjects: subject: Algebraic Geometry (math.AG)

subject: 14L30, 14A20

description: In this paper, we study quotients of groupoids and coarse moduli spaces of stacks in a general setting. Geometric quotients are not always categorical, but we present a natural topological condition under which a geometric quotient is categorical. We also show the existence of geometric quotients of finite flat groupoids and give explicit local descriptions. Exploiting similar methods, we give an easy proof of the existence of quotients of flat groupoids with finite stabilizers. As the proofs do not use noetherian methods and are valid for general algebraic spaces and algebraic stacks, we obtain a slightly improved version of Keel and Mori's theorem.

Byzantine Fault-Tolerant Causal Ordering and Causality Detection in Distributed Systems
Creators: name: Misra, Anshuman
Publisher: name: University of Illinois at Chicago
Year: 2024

description: This thesis is a comprehensive study of causal ordering and causality detection algorithms in the Byzantine failure model across a variety of system settings. This includes proving impossibility results for problems that may appear to be solvable and presenting solutions in the form of algorithms with correctness proofs when problems are solvable. The first part of this thesis deals with Byzantine fault-tolerant causality detection. Causality detection is a fundamental problem in distributed computing and deals with determining an ordering across events in a distributed execution. Determining causality is a critical tool in reasoning about and designing distributed systems. Further, there are many applications of causality detection including determining consistent recovery points in distributed databases, deadlock detection, termination detection, distributed predicate detection, distributed debugging and monitoring, and the detection of race conditions and other synchronization errors. In this thesis, we prove a fundamental impossibility result for the causality detection problem - It is impossible to detect causality across events under Byzantine failures in an asynchronous system. In light of this result, we developed a causality detection protocol for synchronous systems. This protocol establishes another fundamental result - the causality detection problem is solvable in synchronous systems. The second part of this thesis deals with Byzantine fault-tolerant causal ordering. The focus is ensuring that message delivery at correct processes does not violate application level semantics characterized by causal relationships. Applications of causal ordering include distributed data stores, fair resource allocation, and collaborative applications such as multiplayer online gaming, social networks, event notification systems, group editing of documents, and distributed virtual environments. We prove a variety of solvability/impossibility results and provide seven causal ordering algorithms along with correctness proofs across different system settings.

Subjects: subject: Quantum Physics (quant-ph)

description: The entanglement content of superpositions of quantum states is investigated based on a measure called {\it concurrence}. Given a bipartite pure state in arbitrary dimension written as the quantum superposition of two other such states, we find simple inequalities relating the concurrence of the state to that of its components. We derive an exact expression for the concurrence when the component states are biorthogonal, and provide elegant upper and lower bounds in all other cases. For quantum bits, our upper bound is tighter than the previously derived bound in [Phys. Rev. Lett. 97, 100502 (2006).]

Efficient estimation of Pauli observables by derandomization

description: We consider the problem of jointly estimating expectation values of many Pauli observables, a crucial subroutine in variational quantum algorithms. Starting with randomized measurements, we propose an efficient derandomization procedure that iteratively replaces random single-qubit measurements with fixed Pauli measurements; the resulting deterministic measurement procedure is guaranteed to perform at least as well as the randomized one. In particular, for estimating any $L$ low-weight Pauli observables, a deterministic measurement on only of order $\log(L)$ copies of a quantum state suffices. In some cases, for example when some of the Pauli observables have a high weight, the derandomized procedure is substantially better than the randomized one. Specifically, numerical experiments highlight the advantages of our derandomized protocol over various previous methods for estimating the ground-state energies of small molecules.

CO+ in M 82: A Consequence of Irradiation by X-rays

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: Based on its strong CO+ emission it is argued that the M 82 star-burst galaxy is exposed to a combination of FUV and X-ray radiation. The latter is likely to be the result of the star-burst superwind, which leads to diffuse thermal emission at ~0.7 keV, and a compact hard, 2-10 keV, source (but not an AGN). Although a photon-dominated region (FUV) component is clearly present in the nucleus of M 82, and capable of forming CO+, only X-ray irradiated gas of density 10^3-10^5 cm^-3 can reproduce the large, ~(1-4)x10^13 cm^-2, columns of CO+ that are observed toward the proto-typical star-burst M 82. The total X-ray luminosity produced by M 82 is weak, ~10^41 erg s^-1, but this is sufficient to drive the formation of CO+.

Blo gsal grub mtha'
Creators: name: MacDonald, Anne Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: This thesis presents the translation and study of the twelfth section of Bio gsal grub mtha', an early fourteenth century Tibetan text composed by the bKa' gdams pa scholar, dBus pa bio gsal. Bio gsal grub mtha' as a whole represents a distinct sort of scholarly literature known as Grub mtha' that finds its roots in Indian siddhānta literature. Tibetan Grub mtha' texts set forth, as the name in translation reveals, the "established tenets" of various Indian, Tibetan, and occasionally Chinese philosophical schools. The section of Bio gsal grub mtha' translated here presents the tenets of the Mādhyamika school of Tibetan Buddhism in general, and their fourteenth century bKa' gdams pa manifestation in particular. The central tenet of Mādhyarnika philosophy is that all phenomena are empty of self-nature. Even that which is discovered to be the ultimate emptiness (stong pa nyid, śunyatā) - is also said to be devoid of any real self-nature. All phenomena are dependent-arisings, lacking reality, existing like dreams and magical illusions. These assertions are discussed in detail in the translation and in the second part of the introduction. Of special interest to scholars of both Indian and Tibetan Buddhism, however, is dBus pa bio gsal's classification of the Mādhyamika subschools. The early Tibetan Buddhist scholars took upon themselves the task of categorizing and inventing names for the various Mādhyamika "schools", and dBus pa bio gsal's classification represents the development of such thought to the fourteenth century. The introduction elucidates both dBus pa bio gsal's divisions of the Mādhyamika sub-schools and elaborates on earlier and later classifications set forth by Tibetan scholars. The investigation provides insight into both the tenets of the Mādhyamika school and the attempts of the Tibetans to arrange the previously unclassified Mādhyamika subschools in a manner that would render them more logical and accessible to themselves and to future generations of scholars.
Behavior Mining for Recommendation
Creators: name: Wang, Yu
Publisher: name: University of Illinois at Chicago
Year: 2024

description: In the era of information explosion, recommender systems are crucial for mitigating user information overload by filtering out irrelevant information and suggesting preferred items or content. The effectiveness of these systems hinges on accurately understanding user prefer- ences through the analysis of vast user behavior records. However, several challenges hinder the optimal performance of recommender systems. Notably, cold-start problems and noise within user behavior records significantly hinder learning user behavior patterns and develop- ing effective recommendation models. Additionally, over-smoothing issues inherent in common recommender system architectures further complicate the creation of intelligent recommender systems. This thesis is articulated through the discussion of four published papers and one paper under review, each addressing these impediments from different perspectives. The first paper tackles cold-start issues through the integration of knowledge graphs, and proposes a learnable sampling strategy to mitigate noise interference from these graphs. The second paper addresses noise in sequential recommendation scenarios via employing Variational Autoencoders (VAEs) to directly capture noise and uncertainty. The third paper overcomes cold-start difficulties by leveraging the knowledge embedded in pretrained large language models, along with a focused capture of user intent dynamics. The fourth paper confronts over-smoothing by incorporating diffusion models into the recommendation processes. Finally, the fifth paper takes a novel approach by utilizing the emergent capabilities of large language models for few-shot inference, offering a broad spectrum approach to the prevailing issues discussed.
Analytical approximations for the speed of pacemaker-generated waves

description: In an oscillatory medium, a region which oscillates faster than its surroundings can act as a source of outgoing waves. Such pacemaker-generated waves can synchronize the whole medium and are present in many chemical and biological systems, where they are a means of transmitting information at a fixed speed over large distances. In this paper, we apply analytical tools to investigate the factors that determine the speed of these waves. More precisely, we apply singular perturbation and phase reduction methods to two types of negative-feedback oscillators, one built on underlying bistability and one including a time delay in the negative feedback. In both systems, we investigate the influence of timescale separation on the resulting wave speed, as well as the effect of size and frequency of the pacemaker region. We compare our analytical estimates to numerical simulations which we described previously [1].

A real Lorentz-FitzGerald contraction

description: Many condensed matter systems are such that their collective excitations at low energies can be described by fields satisfying equations of motion formally indistinguishable from those of relativistic field theory. The finite speed of propagation of the disturbances in the effective fields (in the simplest models, the speed of sound) plays here the role of the speed of light in fundamental physics. However, these apparently relativistic fields are immersed in an external Newtonian world (the condensed matter system itself and the laboratory can be considered Newtonian, since all the velocities involved are much smaller than the velocity of light) which provides a privileged coordinate system and therefore seems to destroy the possibility of having a perfectly defined relativistic emergent world. In this essay we ask ourselves the following question: In a homogeneous condensed matter medium, is there a way for internal observers, dealing exclusively with the low-energy collective phenomena, to detect their state of uniform motion with respect to the medium? By proposing a thought experiment based on the construction of a Michelson-Morley interferometer made of quasi-particles, we show that a real Lorentz-FitzGerald contraction takes place, so that internal observers are unable to find out anything about their `absolute ' state of motion. Therefore, we also show that an effective but perfectly defined relativistic world can emerge in a fishbowl world situated inside a Newtonian (laboratory) system. This leads us to reflect on the various levels of description in physics, in particular regarding the quest towards a theory of quantum gravity.

Modelling strong interactions and longitudinally polarized vector boson scattering

Year: 2007
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study scattering of the electroweak gauge bosons in 5D warped models. Within two different models we determine the precise manner in which the Higgs boson and the vector resonances ensure the unitarity of longitudinal vector boson scattering. We identify three separate scales that determine the dynamics of the scattering process in all cases. For a quite general background geometry of 5D, these scales can be linked to a simple functional of the warp factor. The models smoothly interpolate between a `composite' Higgs limit and a Higgsless limit. By holographic arguments, these models provide an effective description of vector boson scattering in 4D models with a strongly coupled electroweak breaking sector.

Toward Automatic Summarization of Hospital Discharge Notes
Creators: name: Landes, Paul
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Traditional methods to perform automatic summarization are rapidly being substituted by methods based on Large Language Models (LLMs). However, it cannot be guaranteed that summaries generated by LLMs contain only content from the source. The goal of my research is to discover new methods that combine language-based graphs and deep learning models to address provenance of content and trustworthiness in automatic summarization.

This is particularly important for summarization in health care. Specifically, I focus on automatically generating discharge summaries, a lengthy medical narrative document written by physicians that summarize a hospital in-patient visit. Automatically generating these summaries would allow more time for physicians to be with patients and ameliorate physician documentation burden and burnout. My method uses language-based graphs to model the source data and an alignment algorithm to pair the source and the potential summary; I demonstrate it on both to the publicly available MIMIC-III corpus and clinical notes written by physicians at UI Health (accessed according to IRB protocol 2024-0109).

Flexible manufacturing in Vancouver's clothing industry
Creators: name: Mather, Charles
Publisher: name: University of British Columbia
Year: 2010

description: Flexible production techniques have been implemented in a number of industries in response to the crisis following the long post World War Two boom. These new methods have recently captured the attention of social scientists from a broad range of perspectives. In the large North American automobile industry, where flexible manufacturing is best documented, firms are introducing programmable equipment, work teams are replacing the assembly line, inventories are kept at a minimum, improving turnaround time and quality are important goals, and markets are smaller as specific consumers are targeted. However, it is becoming increasingly clear that the experience of the automobile industry is not representative of other manufacturing sectors. The implementation of the new techniques is likely to be different where the organisation of production is different, the structure of the industry is less concentrated, and where norms of consumption are distinct. This thesis focuses on the clothing industry in Vancouver, British Columbia. For this study, interviews were conducted with fourteen clothing firms in the city, ten workers (most of whom were Chinese female immigrants), union officials, equipment salespeople and a government official. The primary research question was to understand the pervasiveness of the new techniques and their effects on workers and the industry in Vancouver. The results of this study suggest that it is overwhelmingly the very large fashion firms that have invested in flexible machinery. These firms are large enough to lay out the capital for the new machines which improve turnaround time and flexibility, both vital for manufacturers of fashion apparel. A second advantage of the equipment for factory owners is that it reduces their dependence on skilled male workers who command the highest wages on the shop floor. For women workers in the industry (machinists), the new machines simply speed up work, making an already debilitating job worse. On the other hand, many smaller fashion firms are unable to raise the capital for the equipment even though the potential benefits are significant. In addition, standardised clothing manufacturers in Vancouver have not purchased the new technology because it does not suit their needs. Firms without the new technology weather downturns in the economy primarily through workers in the secondary labour market, which, in Vancouver is dominated by immigrant women. At this stage it seems that are barriers to the widespread implementation of flexible equipment in Vancouver clothing industry.

This unique transformation accompanies a Fermi surface reconstruction, demarcating competing ordered phases suitably described with localized and itinerant description of the magnetic $5f$-electrons. Ferromagnetic fluctuations over a wide range of temperatures and pressures in the pressure-induced low temperature phase are evidenced by a robust $T^{5/3}$ temperature dependence of resistivity up to 11 GPa, which is a characteristic of elusive marginal Fermi-liquid state.

description: An integrated and automated smart structures approach for structural health monitoring is presented, utilizing an array of piezoelectric transducers attached to or embedded within the structure for both actuation and sensing. The system actively interrogates the structure via broadband excitation of multiple actuators across a desired frequency range. The structure's vibration signature is then characterized by computing the transfer functions between each actuator/sensor pair, and compared to the baseline signature. Experimental results applying the system to local area damage detection in a MD Explorer rotorcraft composite flexbeam are presented.

description: Among active galactic nuclei, blazars show extreme variability properties. We here investigate the case of the BL Lac object S4 0954+65 with data acquired in 2019-2020 by the Transiting Exoplanet Survey Satellite (TESS) and by the Whole Earth Blazar Telescope (WEBT) Collaboration. The 2-min cadence optical light curves provided by TESS during three observing sectors of nearly one month each, allow us to study the fast variability in great detail. We identify several characteristic short-term time-scales, ranging from a few hours to a few days. However, these are not persistent, as they differ in the various TESS sectors. The long-term photometric and polarimetric optical and radio monitoring undertaken by the WEBT brings significant additional information, revealing that i) in the optical, long-term flux changes are almost achromatic, while the short-term ones are strongly chromatic; ii) the radio flux variations at 37 GHz follow those in the optical with a delay of about three weeks; iii) the range of variation of the polarization degree and angle is much larger in the optical than in the radio band, but the mean polarization angles are similar; iv) the optical long-term variability is characterized by a quasi-periodicity of about one month. We explain the source behaviour in terms of a rotating inhomogeneous helical jet, whose pitch angle can change in time.

description: We delve deeper into the compelling regularizing effect of the Brownian-time Brownian motion density, $\KBtxy$, on the space-time-white-noise-driven stochastic integral equation we call BTBM SIE, which we recently introduced. In sharp contrast to second order heat-based SPDEs--whose real-valued mild solutions are confined to $d=1$--we prove the existence of solutions to the BTBM SIE in $d=1,2,3$ with dimension-dependent and striking Holder regularity, under both less than Lipschitz and Lipschitz conditions. In space, we show an unprecedented nearly local Lipschitz regularity for $d=1,2$--roughly, the SIE is spatially twice as regular as the Brownian sheet in these dimensions--and nearly local Hölder 1/2 regularity in d=3. In time, our solutions are locally Hölder continuous with exponent $γ\in(0,(4-d)/(8))$ for $1\le d\le3$. To investigate our SIE, we (a) introduce the Brownian-time random walk and we use it to formulate the spatial lattice version of the BTBM SIE; and (b) develop a delicate variant of Stroock-Varadhan martingale approach, the K-martingale approach, tailor-made for a wide variety of kernel SIEs including BTBM SIEs and the mild forms of many SPDEs of different orders on the lattice. Here, solutions types to our SIE are both direct and limits of their lattice version. The BTBM SIE is intimately connected to intriguing fourth order SPDEs in two ways. First, we show that it is connected to the diagonals of a new unconventional fourth order SPDE we call parametrized BTBM SPDE. Second, replacing $\KBtxy$ by the intimately connected kernel of our recently introduced imaginary-Brownian time-Brownian-angle process (IBTBAP), our SIE becomes the mild form of a Kuramoto-Sivashinsky SPDE with linear PDE part. Ideas developed here are adapted in separate papers to give a new approach, via our explicit IBTBAP representation, to many KS-type SPDEs in multi spatial dimensions.

Impact of a Brief Fentanyl Educational Intervention on Demand for Cocaine mixed with Fentanyl
Creators: name: Nunez, Cecilia

description: Individuals who use cocaine are at increased risk of overdose related to fentanyl in the cocaine supply, yet few interventions address fentanyl risks in people who use cocaine. Demand tasks use hypothetical decisions about drug purchases to quantify likely real-world behavior. My cocaine demand task, the Adulterated Cocaine Purchase Task, contrasts planned purchases of cocaine when there is 0% probability (no chance) the cocaine is mixed with fentanyl vs. 10% probability (in 10 chance) the cocaine is mixed with fentanyl. No previous studies have examined the impact of fentanyl education on cocaine demand. This pilot study tested the effects of a brief online fentanyl educational intervention on demand for cocaine mixed with fentanyl, fentanyl knowledge, and stated intentions to use harm reduction strategies when taking cocaine (e.g., using test strips, taking a tester dose, carrying naloxone). I hypothesized that participants in the fentanyl education intervention group would show stronger reductions in demand (intensity) for cocaine mixed with fentanyl relative to those in the control group, and secondarily, that they would show increased fentanyl knowledge, and increased intentions to use other harm reduction strategies when taking cocaine.

Using a between-subjects design, participants who reported purchasing cocaine in the past year (N = 58) were randomly assigned to complete test measures either following (intervention group; n = 30) or before receiving (control group; n = 28) fentanyl education. Test measures consisted of the Adulterated Cocaine Purchase Task, self-reported fentanyl knowledge, and harm reduction strategies. Demographics and substance use history were also assessed.

Findings suggested that providing brief fentanyl education significantly increased fentanyl knowledge. Results also indicated that higher probability (1 in 10 chance) of fentanyl admixture was consistently related to decreased cocaine demand across multiple demand indices (e.g., reducing their consumption when cocaine is free). However, providing brief education did not lead to stronger reductions in demand for cocaine mixed with fentanyl relative to those in the control group. Results also showed that fentanyl education and harm reduction behaviors were not significantly related. Findings from this research study further suggest the urgent need to prioritize strategies aside from education to address overdose risk among people who use cocaine.
Radiation-dominated area metric cosmology

description: We provide further crucial support for a refined, area metric structure of spacetime. Based on the solution of conceptual issues, such as the consistent coupling of fermions and the covariant identification of radiation fields on area metric backgrounds, we show that the radiation-dominated epoch of area metric cosmology is equivalent to that epoch in standard Einstein cosmology. This ensures, in particular, successful nucleosynthesis. This surprising result complements the previously derived prediction of a small late-time acceleration of an area metric universe.

Signatures of Dimensionality and Symmetry in Exciton Bandstructure: Consequences for Time-Evolution

description: Exciton dynamics, lifetimes and scattering are directly related to the exciton dispersion, or bandstructure. While electron and phonon bandstructures are well understood and can be easily calculated from first principles, the exciton bandstructure is commonly conflated with the underlying electronic bandstructure, where the exciton dispersion is assumed to follow the same dispersion as the electron and hole bands from which it is composed (i.e., the effective mass model). Here, we present a general theory of exciton bandstructure within both ab initio and model Hamiltonian approaches. We show that contrary to common assumption, the exciton bandstructure contains non-analytical discontinuities -- a feature which is impossible to obtain from the electronic bandstructure alone. These discontinuities are purely quantum phenomena, arising from the exchange scattering of electron-hole pairs. We show that the degree of these discontinuities depends on materials' symmetry and dimensionality, with jump discontinuities occurring in 3D and different orders of removable discontinuities in 2D and 1D. We connect these unexpected features to the early stages of exciton dynamics, which shows remarkable correspondence with recent experimental observations and suggests that the measured diffusion patterns are influenced by the underlying exciton bandstructure.

description: M dwarfs are ideal targets for the search of Earth-size planets in the habitable zone using the radial velocity method, attracting the attention of many ongoing surveys. As a by-product of these surveys, new multiple stellar systems are also found. This is the case also for the CARMENES survey, from which nine new SB2 systems have already been announced. Throughout the five years of the survey, the accumulation of new observations has resulted in the detection of several new multiple stellar systems with long periods and low radial-velocity amplitudes. Here, we newly characterise the spectroscopic orbits and constrain the masses of eight systems and update the properties of a system that we reported earlier. We derive the radial velocities of the stars using two-dimensional cross correlation techniques and template matching. The measurements are modelled to determine the orbital parameters of the systems. We combine CARMENES spectroscopic observations with archival high-resolution spectra from other instruments to increase the time-span of the observations and improve our analysis. When available, we also added archival photometric, astrometric, and adaptive optics imaging data to constrain the rotation periods and absolute masses of the components. We determine the spectroscopic orbits of nine multiple systems, eight of which are presented for the first time. The sample is composed of five SB1s, two SB2s, and two ST3s. The companions of two of the single-line binaries, GJ 3626 and GJ 912, have minimum masses below the stellar boundary and, thus, could be brown dwarfs. We find a new white dwarf in a close binary orbit around the M star GJ 207.1. From a global fit to radial velocities and astrometric measurements, we are able to determine the absolute masses of the components of GJ 282C, which is one of the youngest systems with measured dynamical masses.

Semi-Lorentz invariance, unitarity, and critical exponents of symplectic fermion models

description: We study a model of N-component complex fermions with a kinetic term that is second order in derivatives. This symplectic fermion model has an Sp(2N) symmetry, which for any N contains an SO(3) subgroup that can be identified with rotational spin of spin-1/2 particles. Since the spin-1/2 representation is not promoted to a representation of the Lorentz group, the model is not fully Lorentz invariant, although it has a relativistic dispersion relation. The hamiltonian is pseudo-hermitian, H^\dagger = C H C, which implies it has a unitary time evolution. Renormalization-group analysis shows the model has a low-energy fixed point that is a fermionic version of the Wilson-Fisher fixed points. The critical exponents are computed to two-loop order. Possible applications to condensed matter physics in 3 space-time dimensions are discussed.
