description: We present two observational campaigns performed with the RXTE satellite on the black hole transient H 1743-322. The source was observed in outburst on two separate occasions between October-November 2008 and May-July 2009. We have carried out timing and spectral analysis of the data set, obtaining a complete state classification of all the observations. We find that all the observations are well described by using a spectral model consisting of a disk-blackbody, a powerlaw + reflection + absorption and a gaussian emission component. During the 2009 outburst the system followed the canonical evolution through all the states seen in black hole transients. In the 2008 outburst only the hard states were reached. The early evolution of the spectral parameters is consistent between the two epochs, and it does not provide clues about the subsequent behavior of the source. The variation of the flux associated to the two main spectral components (i.e. disk and powerlaw) allows us to set a lower limit to the orbital inclination of the system of >= 43°.

description: We develop a procedure to reproduce the ten-dimensional generalized supergravity equations from T-duality covariant equations, that facilitates generalization to U-duality covariant formulations of eleven-dimensional supergravity. The latter leads to a modification of the eleven-dimensional supergravity equations with terms that contain a rank-2 tensor field $J^{mn}$ which is the eleven-dimensional analog of the non-unimodularity Killing vector $I^m$ in ten dimensions.

description: There is no unique and widely accepted definition of the complexity measure (CM) of a many-fermion wave function in the presence of interactions. The simplest many-fermion wave function is a Slater determinant. In shell-model or configuration interaction (CI) and other related methods, the state is represented as a superposition of a large number of Slater determinants, which in case of CI calculations reaches about 20 billion terms. Although in practice this number has been used as a CM for decades, it is ill defined: it is not unique, and it depends on the particular type and the number of single-particle wave functions used to construct the Slater determinants. The canonical wave functions/natural orbitals and their corresponding occupation probabilities are intrinsic properties of any many-body wave function, irrespective of the representation, and they provide a unique solution to characterize the CM. The non-negative orbital entanglement entropy, which vanishes for a Slater determinant, provides the simplest CM, while a more complete measure of complexity is the entanglement spectrum. We illustrate these aspects in the case of a complex non-equilibrium time-dependent process, induced nuclear fission described within a real-time Density Functional Theory framework extended to superfluid systems, which can describe simultaneously the long-range and the short range correlations between fermions.

Neel to staggered dimer order transition in a generalized honeycomb lattice Heisenberg model

description: We study a generalized honeycomb lattice spin-1/2 Heisenberg model with nearest-neighbor antiferromagnetic 2-spin exchange, and competing 4-spin interactions which serve to stabilize a staggered dimer state which breaks lattice rotational symmetry. Using a combination of quantum Monte Carlo numerics, spin wave theory, and bond operator theory, we show that this model undergoes a strong first-order transition between a Neel state and a staggered dimer state upon increasing the strength of the 4-spin interactions. We attribute the strong first order character of this transition to the spinless nature of the core of point-like Z(3) vortices obtained in the staggered dimer state. Unlike in the case of a columnar dimer state, disordering such vortices in the staggered dimer state does not naturally lead to magnetic order, suggesting that, in this model, the dimer and Neel order parameters should be thought of as independent fields as in conventional Landau theory.

SU(3) Breaking in Charmless B Decays

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

description: There are many charmless B decay pairs whose amplitudes are related by U spin (d s) or flavor SU(3). The theoretical uncertainty in any analysis involving such pairs must take into account U-spin/SU(3) breaking. In the past, such considerations generally used theoretical input, but we show that this can be experimentally measured. We present lists of two- and three-body decay pairs from which the size of the breaking can be obtained. We detail the values of U-spin/SU(3) breaking given by the present experimental data. One pair -- Bd -> pi+ pi- and Bd -> pi- K+ -- exhibits large nonfactorizable breaking. We present other signals of SU(3) breaking in two- and three-body decays, and discuss further tests for nonfactorizable effects. Finally, we also point out that the pure-penguin decay Bs -> Kbar0 Kbar0 K0 is intriguing because it can be used to cleanly probe the Bs-Bsbar mixing phase.

The role of facilitation in the structure of tropical bird communities : a case study of mixed-species flocks
Creators: name: Munoz, Jenny
Publisher: name: University of British Columbia
Year: 2016

description: Understanding the influence of species interactions on community structure is a long-standing goal in ecology. While many studies have focused on negative biotic interactions, the role of other mechanisms has received less attention, in particular, facilitation. In birds, a striking case of facilitation occurs in mixed-species flocks, in which individuals of different species move and forage as a group to obtain benefits from the association. These associations of species in mixed flocks have been described in different habitats during the last century; however, there is still much debate regarding the prevalence of this foraging strategy and the role it plays in Neotropical bird communities. In this study, I integrated data from mixed species flocks observations and species occurrence to investigate how facilitative interactions influence the structure of Neotropical bird communities across a 3000-m elevational gradient on the eastern slope of the Andes in Peru. First, I examine how the structure of mixed flocks changes across elevations. Second, I quantify the stability of these multispecies groups over time. Third, I evaluate the association of several key habitat variables with flock diversity. Finally, utilizing a dataset for the entire forest bird community, I assess the prevalence and importance of mixed-species flocks across the gradient. The results showed that flocks were highly organized and stable across elevations. Flocks across the gradient exhibited a similar general structure, composed of a stable core group of species and a more dynamic component of attending species. This spatial and temporal analysis suggests that the stability of mixed-species flocks in the Andes is similar to what has been previously described in the Amazonian lowlands, with flocks exhibiting stable home ranges and core member composition over time. Vegetation structure explained 63% of variation in flock richness along the gradient, with number of trees and canopy height as primary predictors. Importantly, this study demonstrates that mixed-species flocks are used by more than a third of bird species present in the community, suggesting that these facilitative interactions are an important and underappreciated component of tropical bird communities.

description: Nano-Fe3O4@Cellulose-NH2-CuI as a novel magnetically separable composite was prepared and fully characterized using various techniques including Fourier transform infrared, X-ray photoelectron and energy-dispersive X-ray spectroscopies, X-ray diffraction, field-emission scanning and transmission electron microscopies, thermogravimetric analysis and vibrating sample magnetometry. To obtain an appropriate structure and also to describe to some extent the different kinds of metal–ligand interactions present in the nano-Fe3O4@Cellulose-NH2-CuI composite, covalent and electrostatic interactions, density functional theory model chemistry and quantum theory of atoms in molecules method were employed, respectively. This cellulose-based heterogeneous catalyst can effectively promote the one-pot three-component reaction of a variety of terminal alkynes bearing substituted phenyls or propargylic alcohol together with substituted benzyl halides and sodium azide, so-called click reaction, in water to afford the corresponding 1,4-disubstituted 1,2,3-triazoles with improved yields and regioselectivity. The magnetic catalyst was conventionally recovered using an external magnet and reused in at least four successive runs under the optimal reaction conditions, without appreciable loss of its activity.

description: We realise a turbulent cascade of wave excitations in a homogeneous 2D Bose gas, and probe on all relevant time and length scales how it builds up from small to large momenta, until the system reaches a steady state with matching energy injection and dissipation. This all-scales view directly reveals the two theoretically expected cornerstones of turbulence formation -- the emergence of statistical momentum-space isotropy under anisotropic forcing, and the spatiotemporal scaling of the momentum distribution at times before any energy is dissipated.

Topological Iwasawa Invariants and Arithmetic Statistics

Year: 2022

description: Given a prime number $p$, we study topological analogues of Iwasawa invariants associated to $\mathbb{Z}_p$-covers of the $3$-sphere that are branched along a link. We prove explicit criteria to detect these Iwasawa invariants, and apply them to the study of links consisting of $2$ component knots. Fixing the prime $p$, we prove statistical results for the average behaviour of $p$-primary Iwasawa invariants for $2$-bridge links that are in Schubert normal form. Our main result, which is entirely unconditional, shows that the density of $2$-bridge links for which the $\mu$-invariant vanishes, and the $\lambda$-invariant is equal to $1$, is $(1-\frac{1}{p})$. We also conjecture that the density of $2$-bridge links for which the $\mu$-invariant vanishes is $1$, and this is significantly backed by computational evidence. Our results are proven in a topological setting, yet have arithmetic significance, as we set out new directions in arithmetic statistics and arithmetic topology.

Persistence of Cryptosporidium parvum in bovine feces during summer and winter exposure
Creators: name: Story, Keith Trizin
Publisher: name: University of British Columbia
Year: 2016

description: Grazing cattle on forested crown lands can be beneficial to the local economy but may also pose a risk to the drinking water extracted from the watershed. A major disturbance that the cattle present to watersheds is the deposition of protozoan pathogens such as Cryptosporidium parvum in their manure. Fecal pathogens deposited near riparian zones can be transmitted into water systems when disturbed by elevated river flow. Although cattle are out of pasture during spring freshet when water flow is high, their feces remain near rivers and streams. If C. parvum persists in feces beyond grazing season and into spring freshet, it may serve as a point source for disease. Nested PCR targeting the Cryptosporidium 18S rRNA gene was used to assess the persistence time of C. parvum oocysts in bovine feces during both the winter and summer seasons in the Okanagan valley, British Columbia. Nested PCR was found to have a limit of detection less than one oocyst per reaction and was of comparable sensitivity to quantitative real-time PCR (3.2 oocyst LOD). Ruptured oocysts were not detectable by nested PCR, Shading, precipitation, freezing/thawing events, temperature, and ultraviolent light were evaluated as factors associated with persistence time. In winter, heavily and moderately forested sites contained detectable C. parvum for less than 67 days, whereas lightly shaded sites showed persistence up to 106 days. Fecal pats were subjected to simulated river flow after winter exposure and no samples leached C. parvum. In summer experiments, feces in lightly forested plots contained no oocysts by 71 days of exposure, whereas heavily and moderately forested plots showed persistence up to 261 and 227 days, respectively. Freeze-thaw events as well as direct ultraviolet light exposure are supported as predominant factors against C. parvum persistence in winter and summer exposures. After three freeze-thaws, 59% of the oocyst population was lost and only 19.3% of the remaining oocysts contained intact cell walls. This research has application in grazing operations as it is provides unprecedentedly low detection limits for monitoring seasonal C. parvum persistence in different shading conditions.

title: Molecular Analysis of the Replication Stress Response Caused by DDX11 Dysfunction and Overexpression
Creators: name: Jegadesan, Nanda Kumar
Publisher: name: The Open University
Year: 2022

description: DDX11 is a conserved iron-sulfur cluster DNA helicase, dysregulated in various cancers and important for normal development. While DDX11 plays roles in DNA repair and mitotic chromosome structure, the molecular mechanism by which DDX11 affects DNA damage response and tumorigenesis is still elusive. We report that loss/depletion of DDX11 in various cancer cell lines, but not in transformed normal cells, confers sensitivity to chemotherapeutic drugs, including Olaparib and Cisplatin. We established DDX11 knockout (KO) and performed synthetic lethality drug screens, uncovering that DDX11 loss sensitizes cells to ATR inhibitors, TOPII poisons and p53 stabilizers. DDX11 averts accumulation of double strand breaks in unperturbed and chemotherapeutic drug treated conditions and plays a crucial role in protecting against MRE11-mediated nascent strand degradation upon replication stress and fork stalling conditions. Focusing on the mechanism by which DDX11 facilitates cellular survival upon DNA damage, we find that DDX11 promotes homologous recombination (HR)-mediated double strand break (DSB) repair by facilitating single stranded DNA (ssDNA) formation and subsequently RPA and RAD51 focus formation. By quantitively measuring ssDNA upon induction of DSBs at specific loci, we find that loss of DDX11 significantly impairs DNA end resection. DDX11 inactivation is synergistic to chemotherapeutic drugs in BRCA1/2-deficient cells by aggravating the DNA damage accumulation. Notably, loss of 53BP1 in DDX11 KO cells partially rescues the HR-defects and their sensitivity to Olaparib and Cisplatin. Mechanistically, DDX11 works downstream of the NHEJ factor 53BP1 to facilitate DNA end resection, RAD51 focus formation and to mediate HR-mediated DSB repair non-redundantly with the HR mediators BRCA1 and BRCA2. Importantly, downregulation of DDX11 re-sensitized BRCA1/2-mutated drug-resistant cancer cells that regained HR proficiency and drug resistance to PARP inhibitors and platinum drugs. Altogether, our results indicate DDX11 as a potential target for both BRCA1/2-deficient as well as HR proficient and drug resistant cancer cells.

description: A $k$-path vertex cover ($k$-PVC) of a graph $G$ is a vertex subset $I$ such that each path on $k$ vertices in $G$ contains at least one member of $I$. Imagine that a token is placed on each vertex of a $k$-PVC. Given two $k$-PVCs $I, J$ of a graph $G$, the $k$-Path Vertex Cover Reconfiguration ($k$-PVCR) under Token Sliding ($\mathsf{TS}$) problem asks if there is a sequence of $k$-PVCs between $I$ and $J$ where each intermediate member is obtained from its predecessor by sliding a token from some vertex to one of its unoccupied neighbors. This problem is known to be $\mathtt{PSPACE}$-complete even for planar graphs of maximum degree $3$ and bounded treewidth and can be solved in polynomial time for paths and cycles. Its complexity for trees remains unknown. In this paper, as a first step toward answering this question, for $k \geq 4$, we present a polynomial-time algorithm that solves $k$-PVCR under $\mathsf{TS}$ for caterpillars (i.e., trees formed by attaching leaves to a path).

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Massive stars (M $\gsim 10$ \msun) form from collapse of parsec-scale molecular clumps. How molecular clumps fragment to give rise to massive stars in a cluster with a distribution of masses is unclear. We search for cold cores that may lead to future formation of massive stars in a massive ($> 10^3$ \msun), low luminosity ($4.6 \times 10^2$ \lsun) infrared dark cloud (IRDC) G030.88+00.13. The \nh3 data from VLA and GBT reveal that the extinction feature seen in the infrared consists of two distinctive clumps along the same line of sight: The C1 clump at 97 \kms-1 coincides with the extinction in the Spitzer 8 and 24 $μ$m. Therefore, it is responsible for the majority of the IRDC. The C2 clump at 107 \kms-1 is more compact and has a peak temperature of 45 K. Compact dust cores and \h2O masers revealed in the SMA and VLA observations are mostly associated with C2, and none is within the IRDC in C1. The luminosity indicates that neither the C1 nor C2 clump has yet to form massive protostars. But C1 might be at a precluster forming stage. The simulated observations rule out 0.1pc cold cores with masses above 8 \msun\ within the IRDC. The core masses in C1 and C2, and those in high-mass protostellar objects suggest an evolutionary trend that the mass of cold cores increases over time. Based on our findings, we propose an empirical picture of massive star formation that protostellar cores and the embedded protostars undergo simultaneous mass growth during the protostellar evolution.

description: Mesial temporal lobe epilepsy (MTLE) is the most common focal epilepsy. One-third of patients have drug-refractory seizures and are left with suboptimal therapeutic options such as brain tissue-destructive surgery. Here, we report the development and characterization of a cell therapy alternative for drug-resistant MTLE, which is derived from a human embryonic stem cell line and comprises cryopreserved, post-mitotic, medial ganglionic eminence (MGE) pallial-type GABAergic interneurons. Single-dose intrahippocampal delivery of the interneurons in a mouse model of chronic MTLE resulted in consistent mesiotemporal seizure suppression, with most animals becoming seizure-free and surviving longer. The grafted interneurons dispersed locally, functionally integrated, persisted long term, and significantly reduced dentate granule cell dispersion, a pathological hallmark of MTLE. These disease-modifying effects were dose-dependent, with a broad therapeutic range. No adverse effects were observed. These findings support an ongoing phase 1/2 clinical trial (NCT05135091) for drug-resistant MTLE.

description: The nuclear level densities of $^{118,119}$Sn and the $γ$-ray strength functions of $^{116,118,119}$Sn below the neutron separation energy are extracted with the Oslo method using the ($^3$He, \,$αγ$) and ($^3$He,$^3$He$^\primeγ$) reactions. The level density function of $^{119}$Sn displays step-like structures. The microcanonical entropies are deduced from the level densities, and the single neutron entropy of $^{119}$Sn is determined to be $(1.7 \pm 0.2)\,k_B$. Results from a combinatorial model support the interpretation that some of the low-energy steps in the level density function are caused by neutron pair-breaking. An enhancement in all the $γ$-ray strength functions of $^{116-119}$Sn, compared to standard models for radiative strength, is observed for the $γ$-ray energy region of $\simeq (4 -11)$ MeV. These small resonances all have a centroid energy of 8.0(1) MeV and an integrated strength corresponding to $1.7(9)\%$ of the classical Thomas-Reiche-Kuhn sum rule. The Sn resonances may be due to electric dipole neutron skin oscillations or to an enhancement of the giant magnetic dipole resonance.
Popular educational books for women as cultural commodities in early modern Japan : a case study of Takara-bako and Oshie-gusa
Creators: name: Suzuki, Saeko
Publisher: name: University of British Columbia

description: This project examines joshiyō ōrai-mono (popular educational publications for women in early modern Japan) as cultural commodities in the transmission of knowledge in relation to three areas: texts/illustrations, commercial publishers, and readers as clients. It also seeks to understand that woodblock prints have the characteristics of repeatable commodities. The project focuses on two encyclopaedia-type joshiyō ōrai-mono books: the 1814 edition of Onna daigaku takara-bako or The Treasure Box of the Women’s Greater Learning, and the second edition of Onna daigaku oshie-gusa or The Elementary Textbook of the Women’s Greater Learning, published in the mid-1840s. Comparing the two books reveals some notable issues. First, the commonality of the contents and physical characteristics of the two books shows that their publisher, Izumiya Ichibē, reused the texts, and copied the design of Takara-bako, a best-selling ōrai-mono, to produce his new book Oshie-gusa. Second, previous scholarship that has developed the literary genre framework for early modern print books cannot always explain the encyclopaedia type of popular educational materials because of their cross-genre characteristics. Third, Takara-bako emphasizes knowledge of waka poetry for female readers as well as providing the list of major female occupation catalogue in that period. Fourth, Oshie-gusa increased the practical contents such as Yin-yang divination and male-female compatibility as a handbook of marriage and family. Fifth, both books stress clothing-related matters, advocating not only household responsibilities but also female virtue based on neo-Confucianist ideology. The comparative analysis of Takara-bako and Oshie-gusa as cultural commodities has demonstrated the commercialization of knowledge in the Tokugawa period (1603-1868). Understanding the mechanisms of commercialization of printed knowledge can help us understand knowledge transmission that is de-commercialized or commercialized in different ways in electronic environments.

description: We compare the Gram-Schmidt and covariant phase-space-basis-vector descriptions for three time-reversible harmonic oscillator problems, in two, three, and four phase-space dimensions respectively. The two-dimensional problem can be solved analytically. The three-dimensional and four-dimensional problems studied here are simultaneously chaotic, time-reversible, and dissipative. Our treatment is intended to be pedagogical, for publication in Communications in Nonlinear Science and Numerical Computation and for use in an updated version of our book on Time Reversibility, Computer Simulation, and Chaos.

description: We study analytically the highly damped quasinormal modes of Kerr black holes in the small angular momentum limit. To check the previous analytic calculations in the literature, which use a combination of radial and tortoise coordinates, we reproduce all the results using the radial coordinate only. According to the earlier calculations, the real part of the highly damped quasinormal mode frequency of Kerr black holes approaches zero in the limit where the angular momentum goes to zero. This result is not consistent with the Schwarzschild limit where the real part of the highly damped quasinormal mode frequency is equal to c^3 ln(3)/(8 pi G M). In this paper, our calculations suggest that the highly damped quasinormal modes of Kerr black holes in the zero angular momentum limit make a continuous transition from the Kerr value to the Schwarzschild value. We explore the nature of this transition using a combination of analytical and numerical techniques. Finally, we calculate the highly damped quasinormal modes of the extremal case in which the topology of Stokes/anti-Stokes lines takes a different form.

description: We report the first experimental demonstration of electrical spin injection, transport and detection in bulk germanium (Ge). The non-local magnetoresistance in n-type Ge is observable up to 225K. Our results indicate that the spin relaxation rate in the n-type Ge is closely related to the momentum scattering rate, which is consistent with the predicted Elliot-Yafet spin relaxation mechanism for Ge. The bias dependence of the nonlocal magnetoresistance and the spin lifetime in n-type Ge is also investigated.

description: We compare form factors in sine-Gordon theory, obtained via the bootstrap, to finite volume matrix elements computed using the truncated conformal space approach. For breather form factors, this is essentially a straightforward application of a previously developed formalism that describes the volume dependence of operator matrix elements up to corrections exponentially decaying with the volume. In the case of solitons, it is necessary to generalize the formalism to include effects of non-diagonal scattering. In some cases it is also necessary to take into account some of the exponential corrections (so-called mu-terms) to get agreement with the numerical data. For almost all matrix elements the comparison is a success, with the puzzling exception of some breather matrix elements that contain disconnected pieces. We also give a short discussion of the implications of the observed behaviour of mu-terms on the determination of operator matrix elements from finite volume data, as occurs e.g. in the context of lattice field theory.

description: The availability of the double-differential charged-current neutrino cross section, measured by the MiniBooNE collaboration using a carbon target, allows for a systematic comparison of nuclear effects in quasi-elastic electron and neutrino scattering. The results of our study, based on the impulse approximation scheme and a state-of-the-art model of the nuclear spectral functions, suggest that the electron cross section and the flux averaged neutrino cross sections, corresponding to the same target and comparable kinematical conditions, cannot be described within the same theoretical approach using the value of the nucleon axial mass obtained from deuterium measurements. We analyze the assumptions underlying the treatment of electron scattering data, and argue that the description of neutrino data will require a new {\em paradigm}, suitable for application to processes in which the lepton kinematics is not fully determined.

description: The Zwin is a relatively small tidal inlet connected to the North Sea through a tidal channel. The inlet is flooded twice a day and it is characterized by the presence of intertidal area with sand banks and salt marshes. From August 2016 until the opening of the dyke in February 2019, large intervention works were carried out to reduce the sediment silting and accretion processes by increasing the amount of water flowing in and out of the inlet (i.e. tidal prism). On 4 February 2019, the intertidal area was nearly doubled when the International Dijk was cut and a part of the former Willem-Leopold polder was made intertidal. This project aims to evaluate the effects of the intervention work and to improve our understanding on the morphodynamics of the Zwin. Detailed topographic and hydrodynamic measurements were carried out in the entrance and inland inlet units over the period covering the time before the opening of the dyke which was on 04/02/2019 and up to 1.9 years afterwards. The results indicate significant morphological changes in the entire inlet system where the main channel has become deeper and wider. Also, it has experienced an eastward migration along the entire inlet. Although a high spatial variability is noted in the morphological evolution, with a clear onshore mobility of the sandy bedforms in the channel especially in the entrance inlet, the sediment balance is stable there, suggesting that sand bypass dominates there. In contrast, the inland inlet has lost a significant sediment volume over the monitoring period. It has also experienced two clear morphological trends with accretion at the west side with a vertical gain of the sand bank and bars, while erosion dominates in the middle and at the east side. There, the channel has become deeper and wider. Both trend means a migration of the channel toward the east. Since the interventions, the water discharge during the flood and ebb phase has significantly increased. It is linearly related to the geometrical characteristics of the tidal basin and water level. Future topographic and hydrodynamic monitoring will allow to fine tune our insights into the morphological response and to estimate the contribution of the different processes controlling the tidal prism in the Zwin inlet.

description: We report the first detection of CO emission at high spectral resolution in the day-side infrared thermal spectrum of an exoplanet. These emission lines, found in the atmosphere of the transiting ultra hot Jupiter (UHJ) WASP-33 b, provide unambiguous evidence of its thermal inversion. Using spectra from the MMT Exoplanet Atmosphere Survey (MEASURE, $R\sim15,000$), covering pre- and post-eclipse phases, we cross-correlate with 1D PHOENIX spectral templates to detect CO at S/N = 7.9 ($v_{sys}=0.15^{+0.64}_{-0.65}$ km/s, $K_{p}=229.5^{+1.1}_{-1.0}$ km/s). Moreover, using cross-correlation-to-log-likelihood mapping, we find that the scaling parameter which controls the spectral line contrast changes with phase. We thus use the general circulation model SPARC/MITgcm post-processed by the 3D gCMCRT radiative transfer code to interpret this variation, finding it consistent with an eastward-shifted hot spot. Pre-eclipse, when the hot spot faces Earth, the thermal profiles are shallower leading to smaller line contrast despite greater overall flux. Post-eclipse, the western part of the day-side faces Earth and has much steeper thermal profiles, leading to larger line contrast despite less overall flux. This demonstrates that within the log-likelihood framework, even relatively moderate resolution spectra can be used to understand the 3D nature of close-in exoplanets, and that resolution can be traded for photon-collecting power when the induced Doppler-shift is sufficiently large. We highlight CO as a good probe of UHJ thermal structure and dynamics that does not suffer from stellar activity, unlike species that are also present in the host star e.g. iron lines.

description: Different deformations of the Poincare symmetries have been identified for various non-commutative spaces (e.g. $κ$-Minkowski, $sl(2,R)$, Moyal). We present here the deformation of the Poincare symmetries related to Snyder space-time. The notions of smooth "K-loop", a non-associative generalization of Abelian Lie groups, and its infinitesimal counterpart given by the Lie triple system are the key objects in the construction.
