description: A novel x-axis tuning fork MEMS gyroscope with "8 vertical springs-proofmass" structure for Coriolis effect detection is presented. Compared with the common single-plane springs, the 8 vertical springs, symmetrically located at the top and bottom sides, more stably suspend the large thick proofmass featuring large capacitance variation and low mechanical noise. A bulk-micromachining technology is applied to obtain the large proofmass and twins-like dual beams. During the fabrication process, the dimensions of the 8 vertical springs are precisely confined by thermal oxide protected limit trenches (LTs) sidewalls and the extreme slowly etched (111)-planes; therefore a small mismatch of less than 30 Hz is achieved before tuning. Initial test shows a sensitivity of 0.15mV/(deg/s) and rate resolution around 0.1deg/s under atmosphere pressure.

Subjects: subject: Cryptography and Security (cs.CR)
subject: FOS: Computer and information sciences

description: We propose the use of the cubic transformation for public-key applications and digital signatures. Transformations modulo a prime p or a composite n=pq, where p and q are primes, are used in such a fashion that each transformed value has only 3 roots that makes it a more efficient transformation than the squaring transformation of Rabin, which has 4 roots. Such a transformation, together with additional tag information, makes it possible to uniquely invert each transformed value. The method may be used for other exponents as well.

Subjects: WP9

description: Task 9.3 foresees the study of a novel charge readout scheme for very large time projection chambers named Vertical Drift. This technology avoids using wires to collect the signals of the electrons, originating from charged particles’ ionization, at the end of their drift path. This kind of development program, included in task 9.3, is unprecedented and innovative in the domain of LAr Time Projection Chambers (TPC). In Vertical Drift the wire planes are replaced by stacks of perforated printed circuit boards integrated in Charge Readout Planes (CRP) with an area of  3 x 3.3 m2 , covering the surface at the top and bottom of the detector. This active surface receives the electrons drifting thanks to a uniform electric field aligned along the vertical axis.  Task 9.3 focuses on the readout of the top-drift volume of the detector. The cryogenic ASIC amplifiers used to read the signals are integrated in this layout in front-end cards hosted in cryostat penetrations “signal feedthrough chimneys” which make them accessible from outside during detector operation. The digitization electronics on the detector roof is cabled to warm-flanges closing the top part of the chimneys. This technology, which is foreseen to equip a DUNE Far Detector module, underwent extensive large-scale tests at the CERN Neutrino Platform in 2021-2022. These tests successfully demonstrated its validity. During 2024 all these technologies reached development maturity ready for production and passed the DUNE Production Readiness Reviews. This deliverable document reports about the overall work and developments performed on the CRP readout system for the DUNE Vertical Drift Far Detector module which is currently in construction.

description: We study thermodynamics of strongly coupled lattice QCD with two colors of massless staggered fermions as a function of the baryon chemical potential $μ$ in 3+1 dimensions using a new cluster algorithm. We find evidence that the model undergoes a weak first order phase transition at $μ=0$ which becomes second order at a finite $μ$. Symmetry considerations suggest that the universality class of these phase transitions should be governed by an $O(N)\times O(2)$ field theory with collinear order, with N=3 at $μ=0$ and N=2 at $μ\neq 0$. The universality class of the second order phase transition at $μ\neq 0$ appears to be governed by the decoupled XY fixed point present in the $O(2)\times O(2)$ field theory. Finally we show that the quantum (T=0) phase transition as a function of $μ$ is a second order mean field transition.

description: Let A be an abelian variety over a number field K. An identity between the L-functions L(A/K_i,s) for extensions K_i of K induces a conjectural relation between the Birch-Swinnerton-Dyer quotients. We prove these relations modulo finiteness of Sha, and give an analogous statement for Selmer groups. Based on this, we develop a method for determining the parity of various combinations of ranks of A over extensions of K. As one of the applications, we establish the parity conjecture for elliptic curves assuming finiteness of Sha[6^\infty] and some restrictions on the reduction at primes above 2 and 3: the parity of the Mordell-Weil rank of E/K agrees with the parity of the analytic rank, as determined by the root number. We also prove the p-parity conjecture for all elliptic curves over Q and all primes p: the parities of the p^\infty-Selmer rank and the analytic rank agree.

description: A simple and fast process for micro-electromechanical (MEM) resonators with deep sub-micron transduction gaps in thin SOI is presented in this paper. Thin SOI wafers are important for advanced CMOS technology and thus are evaluated as resonator substrates for future co-integration with CMOS circuitry on a single chip. As the transduction capacitance scales with the resonator thickness, it is important to fabricate deep sub-micron trenches in order to achieve a good capacitive coupling. Through the combination of conventional UV-lithography and focused ion beam (FIB) milling the process needs only two lithography steps, enabling therefore a way for fast prototyping of MEM-resonators. Different FIB parameters and etching parameters are compared in this paper and their effect on the process are reported.

description: By considering the continuous model for graphene, we analytically study a special gauge field for the edge state. The gauge field explains the properties of the edge state such as the existence only on the zigzag edge, the partial appearance in the $k$-space, and the energy position around the Fermi energy. It is demonstrated utilizing the gauge field that the edge state is robust for surface reconstruction, and the next nearest-neighbor interaction which breaks the particle-hole symmetry stabilizes the edge state.

description: At the Department of Electron Devices a cheap, more or less CMOS process compatible capacitive type RH sensor has been developed. Capacitive sensors are based on dielectric property changes of thin films upon water vapour uptake which depends on the surrounding media's relative humidity content. Because of the immense surface-to-volume ratio and the abundant void fraction, very high sensitivities can be obtained with porous ceramics. One of the ceramics to be used is porous Al2O3, obtained by electrochemical oxidation of aluminium under anodic bias. The average pore sizes are between 6...9 nm. In our paper we intend to demonstrate images representing the influence of the technological parameters on the porous structure and the device sensitivity.

description: Topological edge modes, which are robust against disorders, have been used to enhance the spatial stability of lasers. Recently, it was revealed that topological lasers can be further stabilized using a novel topological phase in non-Hermitian photonic topological insulators. Here we propose a procedure to realize topologically protected modes extended over a d-dimensional bulk by introducing an imaginary gauge field. This generalizes the idea of zero-energy extended modes in the one-dimensional Su-Schrieffer-Heeger lattice into higher dimensional lattices allowing a d-dimensional bulky mode that is topologically protected. Furthermore, we numerically demonstrate that the topological bulk lasing mode can achieve high temporal stability superior to topological edge mode lasers. In the exemplified topological extended mode in the kagome lattice, we show that large regions of stability exist in its parameter space.

description: We consider the renormalisation of composite quark-antiquark operators with one and two lattice covariant derivatives related to the lowest moments of generalised parton distributions (GPDs) and meson distribution amplitudes (DAs). Their matrix elements are calculated in one-loop lattice perturbation theory for non-zero momentum transfer. Using clover and overlap fermions we present the resulting matrices of mixing and renormalisation factors. For overlap fermions we explicitly check the absence of mixing with lower-dimensional operators of different chirality in particular representations of the hypercubic group. This feature favours the use of chiral fermions.

description: Today, hot embossing and injection molding belong to the established plastic molding processes in microengineering. Based on experimental findings, a variety of microstructures have been replicated so far using the processes. However, with increasing requirements regarding the embossing surface and the simultaneous decrease of the structure size down into the nanorange, increasing know-how is needed to adapt hot embossing to industrial standards. To reach this objective, a German-Canadian cooperation project has been launched to study hot embossing theoretically by a process simulation and experimentally. The present publication shall report about the first results of the simulation - the modeling and simulation of large area replication based on an eight inch microstructured mold.

An analysis of UNC-52/perlecan domain IV immunoglobulin repeats in myofilament assembly of Caenorhabditis elegans
Creators: name: Bush, Jason Allan
Publisher: name: University of British Columbia
Year: 2009

description: The unc-52(II) gene encodes the nematode homologue of perlecan, a mammalian basement membrane (BM) proteoglycan. UNC-52 is essential for proper myofilament assembly and muscle attachment in C. elegans. The longest predicted UNC-52 protein has five structural domains, including a LDL-receptor-like domain (domain II), a laminin-like domain (domain III), an NCAM-like domain (domain IV) and a globular laminin-like domain (domain V). The unc-52 gene consists of 37 exons which, through alternative splicing, generate a number of protein isoforms. These isoforms show both tissue and temporal specificity. The domain structure of unc-52 lends itself to regulation via alternative splicing. In particular, domain IV contains multiple copies of an immunoglobulin-like repeat (Ig-repeat) and many of the repeats are encoded by individual exons. Alternative splicing of exons 16, 17 and 18 alters the number of Ig-repeats within this domain. Null mutations in unc-52 lead to a lethal Pat (paralyzed arrested elongation at two-fold) phenotype (e.g. st549), while mutations in exons 16-18 lead to a viable Unc phenotype. Through the sequence analysis of two new unc-52 mutations, st560 and ra112, I established that domain IV-containing isoforms of unc-52 are critical for myofilament assembly during early development. These two mutations both lead to a Pat phenotype and result in premature truncation of UNC-52 isoforms with domain IV; st560 is a stop codon in exon 13; and rall2 is an deletion removing several Ig-encoding exons within domain IV. Using a Tel excision and double-strand break repair scheme to vary the number of Ig repeats within an isoform, I addressed the functional significance of domain IV in establishing proper muscle assembly. I sought to determine the minimal number of Ig repeats necessary within domain IV to allow proper myofilament assembly and to determine the role of combinatorial Ig repeats in assembly. I characterized eight in-frame deletion alleles created by Tel excision which eliminate from 1 to 4 Ig repeats. Animals homozygous for these deletions appear wild-type in movement and muscle structure. The mec-8 gene encodes a putative RNA-binding protein that is required for some of the alternative splicing of unc-52 (Lundquist et al., 1996). In the absence of MEC-8 function, otherwise viable mutations in the alternatively-spliced region of unc-52 are lethal because the affected exons are no longer spliced out of embryonic unc-52 pre-mRNA (Lundquist et al., 1996). I constructed several mec-8; unc-52(deletion) double mutants to ask whether MEC-8 function was still required in the absence of its splicing target. I found that mec-8(null); unc-52(viable deletion) combinations are phenotypically wild-type, suggesting a complete independence from mec-8.

description: We measured the optical signature of the charge density waves (CDWs) in the multiband conductor TTF[Ni(dmit)2]2 by electronic Raman scattering. At low energies, a hump develops below 60 K. This hump is associated to the amplitude mode of the CDW with an energy around 9 meV. Raman symmetry-resolved measurements show that the CDW amplitude mode is anisotropic and that the CDW can be associated to the band nesting of Ni(dmit)2 chains.

description: The modification of the Paschos-Wolfenstein relation is investigated when the charge symmetry violations of valence and sea quark distributions in the nucleon are taken into account. We also study qualitatively the impact of charge symmetry violation (CSV) effect on the extraction of $\sin^{2}θ_{w}$ from deep inelastic neutrino- and antineutrino-nuclei scattering within the light-cone meson-baryon fluctuation model. We find that the effect of CSV is too small to give a sizable contribution to the NuTeV result with various choices of mass difference inputs, which is consistence with the prediction that the strange-antistrange asymmetry can account for largely the NuTeV deviation in this model. It is noticeable that the effect of CSV might contribute to the NuTeV deviation when the larger difference between the internal momentum scales, $α_{p}$ of the proton and $α_{n}$ of the neutron, is considered.

description: Image forensic plays a crucial role in both criminal investigations (e.g., dissemination of fake images to spread racial hate or false narratives about specific ethnicity groups) and civil litigation (e.g., defamation). Increasingly, machine learning approaches are also utilized in image forensics. However, there are also a number of limitations and vulnerabilities associated with machine learning-based approaches, for example how to detect adversarial (image) examples, with real-world consequences (e.g., inadmissible evidence, or wrongful conviction). Therefore, with a focus on image forensics, this paper surveys techniques that can be used to enhance the robustness of machine learning-based binary manipulation detectors in various adversarial scenarios.

description: This paper presents the design, fabrication and preliminary experimental results of a flexure plate wave (FPW) resonator using sol-gel derived lead zirconate titanates (PZT) thin films. The resonator adopts a two-port structure with reflecting grates on the composite membrane of PZT and SiNx. The design of the reflecting grate is derived from a SAW resonator model using COM theory to produce a sharp resonant peak. The comparison between the mass and the viscosity effects from the theoretical expression illustrates the applications and the constraints of the proposed device in liquid sensing. Multiple coatings of sol-gel derived PZT films are adopted because of the cost advantage and the high electromechanical coupling effect over other piezoelectric films. The fabrication issues of the proposed material structure are addressed. Theoretical estimations of the mass and the viscosity effects are compared with the experimental results. The resonant frequency has a good linear correlation with the density of low viscosity liquids, which demonstrate the feasibility of the proposed device.

description: We employ an agent-based model for cultural dynamics to investigate the effects of spatial heterogeneities on the collective behavior of a social system. We introduce heterogeneity as a random distribution of defects or imperfections in a two-dimensional lattice. Two types of defects are considered separately: obstacles that represent geographic features, and opinion leaders, described as agents exerting unidirectional influence on other agents. In both cases, we characterize two collective phases on the space of parameters of the system, given by the density of defects and a quantity expressing the number of available states: one ordered phase, consisting of a large homogeneous group; and a disordered phase, where many small cultural groups coexist. In the case of leaders, the homogeneous state corresponds to their state. We find that a high enough density of obstacles contributes to cultural diversity in the system. On the other hand, we find a nontrivial effect when opinion leaders are distributed in the system: if their density is greater than some threshold value, leaders are no longer efficient in imposing their state to the population, but they actually promote multiculturality. In this situation, we uncover that leaders, as well as obstacles, serve as locations for the formation of boundaries and segregation between different cultural groups. Moreover, a lower density of leaders than obstacles is needed to induce multiculturality in the system.

description: Aims. This study aims to determine the level and constancy of the Spite plateau as definitively as possible from homogeneous high-quality VLT-UVES spectra of 19 of the most metal-poor dwarf stars known. Methods. Our high-resolution (R ~ 43000), high S/N spectra are analysed with OSMARCS 1D LTE model atmospheres and turbospectrum synthetic spectra to determine effective temperatures, surface gravities, and metallicities, as well as Li abundances for our stars. Results. Eliminating a cool subgiant and a spectroscopic binary, we find 8 stars to have -3.5 < [Fe/H] < -3.0 and 9 stars with -3.0 < [Fe/H] < -2.5. Our best value for the mean level of the plateau is A(Li) =2.10 +- 0.09. The scatter around the mean is entirely explained by our estimate of the observational error and does not allow for any intrinsic scatter in the Li abundances. In addition, we conclude that a systematic error of the order of 200 K in any of the current temperature scales remains possible. The iron excitation equilibria in our stars support our adopted temperature scale, which is based on a fit to wings of the Halpha line, and disfavour hotter scales, which would lead to a higher Li abundance, but fail to achieve excitation equilibrium for iron. Conclusions. We confirm the previously noted discrepancy between the Li abundance measured in extremely metal-poor turnoff stars and the primordial Li abundance predicted by standard Big-Bang nucleosynthesis models adopting the baryonic density inferred from WMAP. We discuss recent work explaining the discrepancy in terms of diffusion and find that uncertain temperature scales remain a major question. (abridged)

description: Several published studies indicate that cattle hide values and edible and inedible cattle slaughtering byproducts influence cattle prices. Most cattle processing byproducts are exported. The worldwide COVID-19 pandemic interrupted many international trade supply chains and fed cattle futures prices declined from $127.43/cwt in January 2020 to $83.83/cwt at the end of April 2020. Much of this decline was the result of uncertainties in supply chains, reductions in the demand for beef by the HRI sector, and disruptions in international trade. In addition, lower hide and edible/inedible byproduct values also contributed to lower cattle prices. We show that 0.6% (or $0.54/cwt) of the reduction in cattle prices was associated with lower non-hide byproduct values. A larger reduction (6.5% or $6.30/cwt) was associated with a 50.3% decline in hide values.

description: education system, particularly in preparatory Career and Technical Education (CTE) programs. This narrative inquiry explores the experiences of female students of color in STEM-focused CTE programs in several Washington State skill centers. By examining the educational trajectories and personal narratives of these women, this study seeks to uncover the challenges, supports, and institutional barriers they faced throughout their K-12 education and into their postsecondary endeavors.
description: Through a series of semi-structured interviews, the five participants shared their stories, offering insights into how cultural expectations, family supports, mentorship, and barriers influenced their pursuit of their individual STEM college and career progression. Yosso's Community Cultural Wealth (CCW) framework provided the theoretical lens for this analysis, emphasizing the forms of capital these women leveraged to navigate predominantly White and male-dominated STEM fields.
description: Findings reveal that aspirational and familial capital was crucial in participants' early interest in STEM, while navigational and resistant capital helped them overcome challenges such as gender bias, racial isolation, feelings of imposter syndrome, and financial barriers. Despite these obstacles, four out of five participants persisted in their STEM pathways, with all transitioning to higher education institutions or STEM-related careers.
description: This study contributes to the literature on educational equity in CTE and skill centers by highlighting the systems changes needed to support the retention and success of female students of color to access STEM programs. Recommendations include enhancing mentorship opportunities, addressing implicit bias in educational settings, and fostering more inclusive learning environments in STEM fields. Ultimately, this research underscores the ongoing importance of culturally responsive approaches to closing the participation gaps for females and minorities in secondary STEM education plus post-secondary college and careers.

The Coulombic pseudogap remains robust well into the quantum Hall regime until it is overshadowed by the cyclotron gap in the TDOS. The pseudogap is modified by in-plane magnetic field, demonstrating a non-trivial effect of in-plane magnetic field on the electron-electron interaction.

description: In this report, we discussed the effect of manipulative-based interventions on improving mathematics computation outcomes for students with mathematics difficulties. We conducted systematic analysis on 23 articles including single case design studies, and group design studies by using random effect meta regression model. This study serves as the first study which combined single case design and group design studies in the data analysis in the field of manipulative-based interventions. We determined that the manipulative-based interventions are effective on improving whole number computation for students with mathematics difficulties. We also found that special education teacher or researcher implemented interventions had a larger effect size than that implemented by general education teachers. However, our conclusion should be considered as preliminary and more exploration on manipulative-based interventions are needed.

description: Lifetime stress exposure has profound effects on neurobiology with lifelong implications for mental health. Epigenetic processes, such as DNA methylation, have been proposed as playing a role in shaping the trajectories of stress-related disorders such as major depression and posttraumatic stress disorder, yet the relationship between stress and DNA methylation has yet to be evaluated in depth. The research presented in this thesis aimed to evaluate 1) the factors associated with chronic biological stress, 2) the relationship between chronic biological stress and DNA methylation, 3) and the impact of acute psychological stress on DNA methylation. Chapters 3 and 4 of this thesis utilized human subjects to investigate the complexity of hair cortisol as a biomarker of chronic stress and its relationship with the epigenome. Results from these studies indicate that chronic biological stress is subtly influenced by both demographic and psychological factors, possibly in a sex-dependent manner. We also report many DNA methylation sites across the genome that are associated with chronic biological stress. Chapter 5 of this thesis aimed to determine the impact of acute stress on the epigenome in humans using a controlled laboratory experiment. For the first time in the literature, we test the influence of acute psychological stress on genome-wide DNA methylation and report novel sites related to stress and immune function that may be sensitive to acute stress, and that are implicated in chronic stress. Taken together, these studies link acute and chronic stress, support the notion that both short- and long-term stress have epigenetic impact, and inform the mechanism of psychopathology. The specific molecular processes by which different types of stress promote epigenetic changes across the lifespan and contribute to the differential susceptibility of males and females to psychiatric morbidity require further investigation.
Domestic violence research in Canada : an assessment and re-direction
Creators: name: Brimner, Tammy Lanette
Publisher: name: University of British Columbia

description: Domestic violence has been identified as a problem for over twenty-five years. However, a number of reviews have demonstrated the lack of research in this area, especially in Canada. In order to encourage and provide direction for future research, past studies must be assessed. Attention must be given to both methodological and theoretical issues and the implications for domestic violence research. The focus of this thesis is the critique of three Canadian surveys. The purpose is: (1) to offer a critique of the methodology and the theoretical assumptions underlying each of these surveys, and (2) to propose revisions to advance the empirical research of domestic violence. The objectives are accomplished through a literature review of domestic violence and through a detailed assessment of the strengths and weaknesses of each of the surveys. This assessment revealed the need for more domestic violence research in Canada, making theoretical and methodological revisions to increase the reliability of these data and the validity of surveys as effective research tools. Theoretically, researchers need to consider a synthesis of existing domestic violence perspectives, emphasizing psychological and interactional theories, in order to provide a fuller understanding of the complexity of domestic violence. Methodologically, future research should focus on both men and women as victims and offenders, creating measurement tools tailored to each gender. Researchers need to further explore the perceptions of men and women about their intimate relationships and how domestic violence affects their lives.

description: Parkinson's disease (PD) is commonly characterized by several motor symptoms, such as bradykinesia, akinesia, rigidity, and tremor. The analysis of patients' fine motor control, particularly handwriting, is a powerful tool to support PD assessment. Over the years, various dynamic attributes of handwriting, such as pen pressure, stroke speed, in-air time, etc., which can be captured with the help of online handwriting acquisition tools, have been evaluated for the identification of PD. Motion events, and their associated spatio-temporal properties captured in online handwriting, enable effective classification of PD patients through the identification of unique sequential patterns. This paper proposes a novel classification model based on one-dimensional convolutions and Bidirectional Gated Recurrent Units (BiGRUs) to assess the potential of sequential information of handwriting in identifying Parkinsonian symptoms. One-dimensional convolutions are applied to raw sequences as well as derived features; the resulting sequences are then fed to BiGRU layers to achieve the final classification. The proposed method outperformed state-of-the-art approaches on the PaHaW dataset and achieved competitive results on the NewHandPD dataset.

description: We report in this paper the design, fabrication and experimental characterization of a piezoelectric MEMS microgenerator. This device scavenges the energy of ambient mechanical vibrations characterized by frequencies in the range of 1 kHz. This component is made with Aluminum Nitride thin film deposited with a CMOS compatible process. Moreover we analyze two possible solutions for the signal rectification: a discrete doubler-rectifier and a full custom power management circuit. The ASIC developed for this application takes advantage of diodes with very low threshold voltage and therefore allows the conversion of extremely low input voltages corresponding to very weak input accelerations. The volume of the proposed generator is inferior to 1mm3 and the generated powers are in the range of 1$μ$W. This system is intended to supply power to autonomous wireless sensor nodes.

description: The present lecture notes are an introduction to selected topics of {\it Galactic Dynamics}. The focus is on topics that we consider more relevant to the main theme of this workshop, {\it Celestial Mechanics}. This is not intended to be a review article. In fact, any of the topics below could be the subject of a separate review. Only the main ideas and notions are introduced, as well as some important currently open problems in each topic. Some relevant results from our own research are also presented. We discuss topics related mostly to the so-called {\it ellipsoidal components} of galaxies. These are \textbf{a)} the dark halos of both elliptical and disk galaxies, \textbf{b)} the luminous matter in elliptical galaxies, and \textbf{c)} the bulges of disk galaxies. We shall only occasionally refer to the dynamics of disks, bars or spiral structure.

SRoll3: A neural network approach to reduce large-scale systematic effects in the Planck High Frequency Instrument maps

description: In the present work, we propose a neural network based data inversion approach to reduce structured contamination sources, with a particular focus on the mapmaking for Planck High Frequency Instrument (Planck-HFI) data and the removal of large-scale systematic effects within the produced sky maps. The removal of contamination sources is rendered possible by the structured nature of these sources, which is characterized by local spatiotemporal interactions producing couplings between different spatiotemporal scales. We focus on exploring neural networks as a means of exploiting these couplings to learn optimal low-dimensional representations, optimized with respect to the contamination source removal and mapmaking objectives, to achieve robust and effective data inversion. We develop multiple variants of the proposed approach, and consider the inclusion of physics informed constraints and transfer learning techniques. Additionally, we focus on exploiting data augmentation techniques to integrate expert knowledge into an otherwise unsupervised network training approach. We validate the proposed method on Planck-HFI 545 GHz Far Side Lobe simulation data, considering ideal and non-ideal cases involving partial, gap-filled and inconsistent datasets, and demonstrate the potential of the neural network based dimensionality reduction to accurately model and remove large-scale systematic effects. We also present an application to real Planck-HFI 857 GHz data, which illustrates the relevance of the proposed method to accurately model and capture structured contamination sources, with reported gains of up to one order of magnitude in terms of contamination removal performance. Importantly, the methods developed in this work are to be integrated in a new version of the SRoll algorithm (SRoll3), and we describe here SRoll3 857 GHz detector maps that will be released to the community.

description: We construct higher spin quasinormal modes algebraically in $D$-dimensional de Sitter spacetime using the ambient space formalism. The quasinormal modes fall into two nonunitary lowest-weight representations of $\mathfrak{so}(1, D)$. From a local QFT point of view, the lowest-weight quasinormal modes of massless higher spin fields are produced by gauge-invariant boundary conserved currents and boundary higher-spin Weyl tensors inserted at the southern pole of the past boundary. We also show that the quasinormal spectrum of a massless/massive spin-$s$ field is precisely encoded in the Harish-Chandra character corresponding to the unitary massless/massive spin-$s$ $\text{SO}(1, D)$ representation.
