description: The dissertation explores the deliberate destruction of cultural heritage under international law. The main thread of theresearch concerns the legal boundaries of cultural memory by examining when a duty to remember cultural heritage can translate into a legal obligation to preserve it - a right to remember- and when, at the same time, there may be a symmetrical legal duty to forget it. In other terms, the dissertation seeks to study not only the “pathological” dimension of destruction but also tracetheborders of destruction by verifying lawful situations in which is possible to recognize “a right to destroy”, b comparing different casesof destruction, or, as the case may be, removal of heritage. Thestudy explores cases of the destruction of heritage in national contexts authorized by domestic governments in light of applicable international norms in both peacetime and wartime contexts. The scope of the research includes mainly examples of tangible cultural heritage (more specifically, public monuments and buildings), which are characterized as contested heritage with accompanying issues of memory and divisive identity narratives. The research will focus on iconoclastic episodes driven by ideological reasons, rooted in three case-studies: Soviet monuments in Ukraine, Confederate iconography in the United States, and the situation of the Rohingya in Myanmar. It will exclude cases of peacetime threats to cultural heritage caused by economic development. The study seeks to enrich the interdisciplinary literature on memory and heritage studies in connection with law.

description: La présente thèse propose une analyse de l'application par un tribunal administratif québécois de l'obligation d'accommodement d'un employeur à l'égard d'un(e) salarié(e) ayant un problème de santé mentale. Cette étude en trois volets fait 1) une revue d'une sélection d'articles et rapports de la littérature en psychologie organisationnelle et gestion des incapacités portant sur le retour au travail des personnes ayant un problème de santé mentale, 2) un rappel des principales décisions de la Cour suprême du Canada portant sur l'obligation d'accommodement en contexte d'emploi pour des personnes handicapées et 3) une analyse approfondie des décisions rendues par les arbitres de grief québécois entre 2010 et 2018 qui se sont penchées sur l'obligation d'accommodement d'un employeur à l'égard d'un(e) salarié(e) ayant un problème de santé mentale. Notre analyse de ces décisions nous permet d'émettre certaines conclusions notamment quant a) à une judiciarisation plus élevée du recours à l'obligation d'accommodement chez les syndiqués que chez les non-syndiqués, b) aux possibilités restreintes d'accommodement lorsqu'il y a un absentéisme de longue durée ou fréquent, c) à l'influence de la taille du milieu de travail sur l'étendue de l'obligation, les grandes entreprises ayant des obligations plus étendues et d) à la nécessité d'une collaboration des parties au processus d'accommodement.

description: A class of beam-like lattice structures, or metabeams under static, sinusoidally distributed transverse loads is discussed. Their neutral axis deflects either in-phase, out-of-phase or shows no deflection, depending on the beam design parameters, and also on the spatial frequency of the static load. These outcomes contrast the behavior of continuum beams, deflecting always in-phase with the load, and they are interpreted on the basis of a positive, negative and near-infinite effective Young's modulus of the structured beams in bending. They also represent a collective effect of the behavior of multiple elements in the lattice that cannot be realized from the performance of an isolated unit cell. A long-range periodic order and nonlocality of the lattice interaction is essential for this unusual behaviors, and those are particularly pronounced at higher wavenumbers, when the load wavelength becomes comparable with the range of direct interactions in the lattice. Theoretical discussion and predictions agree well with numerical experiments performed on the basis of commonly accepted models. Practical applications could be found in advanced reinforcing materials for building foundations, deformation mitigation for lightweight structures and bridges, and in smart mechanical systems able to differentiate external stimuli and to respond selectively.

description: Nitrophenols (NPs) and their derivatives are highly toxic, mutagenic and bio-refractory pollutants commonly present in natural water resources and industrial wastewater. To remove NPs from water, N-doped graphitic carbon (NGC) and NGC adsorbent containing titanium dioxide (NGC–TiO2) were synthesized by pyrolysis of microcrystalline cellulose and dopamine mixture, and the mixture along with TiO2 at 500°C, respectively. NCG-TiO2 was thoroughly characterized using various analytical techniques. NP adsorption on the NGC–TiO2 adsorbent surface was studied by varying the pH, initial concentration of NP, and adsorbent dose. The results showed that the most efficient adsorption was achieved at pH 3. After 4 h sonication at pH 3, 80% 4-NP adsorption was achieved using NGC–TiO2 compared to 74% with NGC adsorbent. The percentage removal of 4-NP was higher than 3-NP which was also higher than 2,4-DNP using NGC–TiO2. 4-NP adsorption best fitted to the Langmuir isotherm plot with R2 value of 0.9981 and adsorption capacity of 52.91 mg g−1. The adsorption process of NP was found to follow a pseudo-second-order kinetic model. The rate constant value for the adsorption of 10−4 M 4-NP at pH 3 using 10 mg of NGC–TiO2 adsorbent was found to be 3.76 × 10−5 g.mg−1.min−1

description: The contributor's father, Robert McKechnie, was born in 1917. Robert lived in a town called Whitburn and worked as a mining engineer. While waiting on his call-up papers, Robert hoped to go to the RAF, but ended up with the Navy. Robert was terrified because he couldn't swim. But he then received another letter that told him to ignore his call-up, because he was in a reserved occupation. During the war, Robert was in Whitburn. The rationing wasn't so bad because it was supplemented by local farms' produce. The contributor said that her father's main memory was of working in a local pit and watching the sky go black, because something was happening in Glasgow. Robert joined the Home Guard and hated it. He was stationed in a valley, signaling from each side of the hill, but found it cold and wet. Whitburn was quiet but a plane crashed in the park and all the locals went down to see it. The contributor said her father remembered going to Glasgow on the back of a bike during the war and going to the matinee performance at the theatre to get back before dark (and maybe to get back before the nightshift). Robert's youngest brother, Andy, was in the RAF and served in Africa. The cigarette case came from Andy. The date on the object is 1946. The contributor wasn't certain on the details of the object's origin - but Andy met an Italian POW during his RAF service, and they became friends. The Italian made cigarette cases, so Andy asked if he would make two for his brothers. The metal is from an airplane. The contributor's mother, Elsie Round, was born in 1922. The contributor noted that her mother's war experience was different as she was brought up in Glasgow. Elsie worked in a munitions factory and watched for incendiary bombs on the roof, although she wasn't sure what to do if she saw one. The main thing the contributor said her mother talked about was rationing, and that she could still hear the bombs. Elsie considered joining the Land Army but decided to stay in the munitions factory with her friends! Elsie remembered being in George Square on VE Day with everybody! She loved being in crowds and people-watching so would have loved it! The contributor said that her parents spoke about war constantly throughout her life. Although, her mother didn't talk about anything specific. The contributor doesn't know if she was traumatized or if she was just a happy-go-lucky 16-year-old who didn't really care! Elsie never told stories about going dancing, but her best friend married a GI and emigrated to Canada! Throughout life, Elsie would say 'during the war...'. Robert loved music his whole life, and the contributor grew up listening to war records.

description: Widespread vaccine coverage for viral diseases could save the lives of millions of people each year. For viral vaccines to be effective, they must be transported and stored in a narrow temperature range of 2-8°C. If temperatures are not maintained, the vaccine may lose its potency and would no longer be effective in fighting disease; this is called the cold storage problem. Finding a way to thermally stabilize a virus and end the need to transport and store vaccines at refrigeration temperatures will increase access to life-saving vaccines. We explore the use of polymer-rich complex coacervates to stabilize viruses. We have developed a method of encapsulating virus particles in liquid complex coacervates that relies on the electrostatic interaction of viruses with polypeptides. In particular, we tested the incorporation of two model viruses; a non-enveloped porcine parvovirus (PPV) and an enveloped bovine viral diarrhea virus (BVDV) into coacervates formed from poly(lysine) and poly(glutamate). We identified optimal conditions (i.e., the relative amount of the two polypeptides) for virus encapsulation, and trends in this composition matched differences in the isoelectric point of the two viruses. Furthermore, we were able to achieve a ~103 – 104-fold concentration of virus into the coacervate phase, such that the level of virus remaining in the bulk solution approached our limit of detection. Lastly, we demonstrated a significant enhancement of the stability of non-enveloped PPV during an accelerated aging study at 60°C over the course of a week. Our results suggest the potential for using coacervation to aid in the purification and formulation of both enveloped and non-enveloped viruses, and that coacervate-based formulations could help limit the need for cold storage throughout the transportation and storage of vaccines based on non-enveloped viruses.

description: The Hell Creek Formation preserves one of the most intensely studied late Cretaceous terrestrial fossil units. Over 22 dinosaur genera are currently recognized from this unit, but the record of juvenile individuals is surprisingly limited. Here, we document a nestling hadrosaur that represents the first occurrence of an articulated nestling dinosaur skeleton from the latest Cretaceous (late Maastrichtian) of North America. The specimen (UCMP 128181) preserves a partial scapula, nearly complete rib cage, vertebral series from the shoulder to mid-tail, a large portion of the pelvic girdle, and both hind limbs through a combination of bone and/or natural impressions in the concretion. It is assignable to the genus Edmontosaurus based on the shape of the prepubic process, or blade, of the pubis. The specimen represents the earliest ontogenetic growth stage of Edmontosaurus cf. annectens and possesses a femur length of 148 mm. It greatly contributes as a new end member to a sample of associated Edmontosaurus skeletons that is well suited for allometrically testing the hypothesized ontogenetic gait shift in hadrosaurs from bipedal juveniles to quadrupedal adults using individual limb proportions. Although UCMP 128181 does not preserve forelimbs, regressions based on associated Edmontosaurus skeletons (N = 25) reveal overall isometry of the forelimb relative to the hind limb, and within each limb. These data indicate that Edmontosaurus nestlings were anatomically capable of fully quadrupedal locomotion and provide no compelling evidence to support an ontogenetic gait shift in hadrosaurids.

description: Since the discovery of high-temperature superconductivity in the thin-film FeSe/SrTiO$_3$ system, iron selenide and its derivates have been intensively scrutinized. Using ab initio density functional theory calculations we review the electronic structures that could be realized in iron-selenide if the structural parameters could be tuned at liberty. We calculate the momentum-dependence of the susceptibility and investigate the symmetry of electron pairing within the random phase approximation. Both the susceptibility and the symmetry of electron pairing depend on the structural parameters in a nontrivial way. These results are consistent with the known experimental behavior of binary iron chalcogenides and, at the same time, reveal two promising new ways of tuning superconducting transition temperatures in these materials. On the one hand by expanding the iron lattice of FeSe at constant iron-selenium distance and, on the other hand, by increasing the iron-selenium distance with unchanged iron lattice.

description: We introduce $\mathbb Z_2$-valued bulk invariants for symmetry-protected topological phases in $2+1$ dimensional driven quantum systems. These invariants adapt the $W_3$-invariant, expressed as a sum over degeneracy points of the propagator, to the respective symmetry class of the Floquet-Bloch Hamiltonian. The bulk-boundary correspondence that holds for each invariant relates a non-zero value of the bulk invariant to the existence of symmetry-protected topological boundary states. To demonstrate this correspondence we apply our invariants to a chiral Harper, time-reversal Kane-Mele, and particle-hole symmetric graphene model with periodic driving, where they successfully predict the appearance of boundary states that exist despite the trivial topological character of the Floquet bands. Especially for particle-hole symmetry, combination of the $W_3$ and the $\mathbb Z_2$-invariants allows us to distinguish between weak and strong topological phases.

description: A surprising result in $e^+ e^-$ collisions is that the particle spectra from the string formed between the expanding quark-antiquark pair have thermal properties even though scatterings appear not to be frequent enough to explain this. We address this problem by considering the finite observable interval of a relativistic quantum string in terms of its reduced density operator by tracing over the complement region. We show how quantum entanglement in the presence of a horizon in spacetime for the causal transfer of information leads locally to a reduced mixed-state density operator. For very early proper time $τ$, we show that the entanglement entropy becomes extensive and scales with the rapidity. At these early times, the reduced density operator is of thermal form, with an entanglement temperature $T_τ=\hbar/(2πk_B τ)$, even in the absence of any scatterings.

description: Understanding transport characteristics of airborne nanotubes and nanofibers is important for assessing their fate in the respiratory system. Typically, diffusion and aerodynamic diameters capture key deposition mechanisms of near-spherical particles such as diffusion and impaction in the submicrometer size range. For nonspherical particles with high aspect ratios, such as aerosolized carbon nanotubes, these diameters can vary widely, requiring their independent measurement. The objective of this study was to develop an approach to provide approximate estimates of aerodynamic- and diffusion-equivalent diameters of airborne carbon nanotubes (CNTs) and carbon nanofibers (CNFs) using their morphological characteristics obtained from electron micrographs. The as-received CNT and CNF materials were aerosolized using different techniques such as dry dispersion and nebulization. Mobility and aerodynamic diameters of test aerosol were directly deduced from tandem measurement of particle mobility and mass. The same test aerosol was mobility-classified and subsequently collected on a microscopy grid for transmission electron microscopy (TEM) analysis. TEM micrographs were used to obtain projected area, maximum projected length, and two-dimensional (2-D) radius of gyration of test particles. Estimates of the aerodynamic diameter and the diffusion diameter were obtained by applying the fractal theory developed for aerosol agglomerates of primary spherical particles. After accounting for the particle dynamic shape factor, estimated aerodynamic diameters agreed with those from the direct measurements (using tandem mobility-mass technique) within 30–40% for the agglomerates with relatively open structures while the diffusion diameters agreed within 40–50%. The uncertainty of these estimates mainly depends on degree of overlapping structures in the microscopy image and nonuniformity in tube diameter. The approach could be useful in calculating approximate airborne properties from microscopy images of CNT and CNF agglomerates with relatively open structures.

description: Designed motoring programs for hyperactivity-induced children can lead to visible improvement in their behavioral problems. Therefore, this study aimed to compare the effect of perceptual-motor exercises and resistance-balance exercises on behavioral disorders in children with attention deficit hyperactivity disorder. In the current research, a semi-experimental design with two groups design with control group was used. A total of 36 boy children aged 12 to 5 years (18 preschoolers and 18 primary school children) with attention deficit hyperactivity disorder who visited the Zehnara rehabilitation clinic in Tehran, randomly assigned to two experimental groups (perceptual-motor exercises) and (resistance-balance exercises) and control group. For data screening and collection, Conners Parents Rating Questionnaire and Child Behavior Checklist (CBCL) were used and the results were analyzed using covariance analysis and Ben-fronni post hoc test. The results showed that the effect of perceptual-motor and resistance-balance exercises on reducing behavioral disorders in children with attention deficit hyperactivity disorder was significant (P <0.001).However, the results of Ben-fronni post hoc test showed that there was no significant difference between two experimental groups in reducing behavioral disorders (P <0.005). According to research results it can be said that motor activity with emphasis on perceptual-motor and resistance-balance exercises can reduce the behavioral disorders of children with attention deficit hyperactivity disorder and use of these programs in the treatment of these children is suggested.

description: We examine Penrose limits of the duality proposed by Guarino, Jafferis and Varela between a type IIA massive background of the type of a warped, squashed $AdS_4\times S^6$, and a 2+1 dimensional IR fixed point of ${\cal N}=8$ super Yang-Mills deformed by Chern-Simons terms to ${\cal N}=2$ supersymmetry. One type of Penrose limit for closed strings corresponds to a large charge closed spin chain, and another, for open strings on giant graviton D-branes, corresponds to an open spin chain on sub-determinant operators. For the first limit, we find that like in the ABJM case, there are functions $f_a(λ)$ that interpolate between the perturbative and nonperturbative (string) regions for the magnon energy. For the second, we are unable to match the gravity result with the expected field theory result, making this model more interesting than ones with more supersymmetry.

description: We present a method for estimating conditionally Gaussian random vectors with random covariance matrices, which uses techniques from the field of machine learning. Such models are typical in communication systems, where the covariance matrix of the channel vector depends on random parameters, e.g., angles of propagation paths. If the covariance matrices exhibit certain Toeplitz and shift-invariance structures, the complexity of the MMSE channel estimator can be reduced to O(M log M) floating point operations, where M is the channel dimension. While in the absence of structure the complexity is much higher, we obtain a similarly efficient (but suboptimal) estimator by using the MMSE estimator of the structured model as a blueprint for the architecture of a neural network. This network learns the MMSE estimator for the unstructured model, but only within the given class of estimators that contains the MMSE estimator for the structured model. Numerical simulations with typical spatial channel models demonstrate the generalization properties of the chosen class of estimators to realistic channel models.

description: The Aerodynamic Aerosol Classifier (AAC) is a novel instrument that selects aerosol particles based on their relaxation time or aerodynamic diameter. Additional theory and characterization is required to allow the AAC to accurately measure an aerosol’s aerodynamic size distribution by stepping while connected to a particle counter (such as a Condensation Particle Counter, CPC). To achieve this goal, this study characterized the AAC transfer function (from 32 nm to 3 μm) using tandem AACs and comparing the experimental results to the theoretical tandem deconvolution. These results show that the AAC transmission efficiency is 2.6–5.1 times higher than a combined Krypton-85 radioactive neutralizer and Differential Mobility Analyzer (DMA), as the AAC classifies particles independent of their charge state. However, the AAC transfer function is 1.3–1.9 times broader than predicted by theory. Using this characterized transfer function, the theory to measure an aerosol’s aerodynamic size distribution using an AAC and particle counter was developed. The transfer function characterization and stepping deconvolution were validated by comparing the size distribution measured with an AAC-CPC system against parallel measurements taken with a Scanning Mobility Particle Sizer (SMPS), CPC, and Electrical Low Pressure Impactor (ELPI). The effects of changing AAC classifier conditions on the particle selected were also investigated and found to be small (<1.5%) within its operating range.

description: Cellular senescence is a stress-induced cell cycle arrest that can be triggered by various stimuli such as telomere shortening, oncogene activation, radiation or chemotherapy. Through their senescence-associated secretory phenotype (SASP), senescent cells shape their microenvironment and have both beneficial and detrimental effects, affecting processes such as tissue repair, inflammation and tumorigenesis. While extensive data exists on the role of therapy-induced senescent tumor and stromal cells, little is known about senescent cancer cells under therapy-naive conditions. The aim of this work was to characterize the role of spontaneously senescent tumor cells (SSTC) under therapy-naïve conditions. SSTC were found in therapy-naive murine and human colorectal carcinoma (CRC), cholangiocarcinoma (CCA) and pancreatic ductal adenocarcinoma (PDAC) as well as in 27 different human and murine tumor lines. Interestingly, the percentage of SSTCs within the lines correlated with their in vitro invasive capacity. Analysis of primary human tumor material also showed an increased frequency of SSTC in patients with regional lymph node metastasis compared to patients with localized disease. Pharmacological senolysis with navitoclax or genetic ablation of SSTC significantly reduced tumor cell invasion in vitro and in vivo, resulting in significantly reduced metastasis in the passive splenic seeding model and in two syngenic mouse models of CRC and CCA. Spontaneous senescence and tumor invasion/metastasis were shown to be functionally linked, with selection of highly invasive and metastatic cells leading to increased SSTC numbers. Collected data suggest a model in which SSTC are derived from a subset of cancer cells with increased resistance to apoptosis, and functional studies confirmed the induction of SSTC in such cells upon exposure to microenvironmental factors such as acidosis or hypoxia. In turn, several SASP factors from SSTC were found to act on neighboring cancer cells to increase their metastatic potential. Overall this thesis pinpoints a crucial role of SSTC for initiation of metastasis. The data harbor important translational implications, as, despite intensified screening and early detection efforts, almost half all human tumors are still diagnosed at advanced stages. Pharmacological senolysis in patients with increased cancer risk might allow to detect more cancers at earlier curative stages and thus greatly increase the prognosis of cancer patients.

description: In order to study the growth and evolution of circumstellar disks around classical Be stars, we analyze optical time-series photometry from the KELT survey with simultaneous infrared and visible spectroscopy from the APOGEE survey and BeSS database for a sample of 160 Galactic classical Be stars. The systems studied here show variability including transitions from a diskless to a disk-possessing state (and vice versa), and persistent disks that vary in strength, being replenished at either regularly or irregularly occurring intervals. We detect disk-building events (outbursts) in the light curves of 28\% of our sample. Outbursts are more commonly observed in early- (57\%), compared to mid- (27\%) and late-type (8\%) systems. A given system may show anywhere between 0 -- 40 individual outbursts in its light curve, with amplitudes ranging up to $\sim$0.5 mag and event durations between $\sim$2 -- 1000 days. We study how both the photometry and spectroscopy change together during active episodes of disk growth or dissipation, revealing details about the evolution of the circumstellar environment. We demonstrate that photometric activity is linked to changes in the inner disk, and show that, at least in some cases, the disk growth process is asymmetrical. Observational evidence of Be star disks both growing and clearing from the inside out is presented. The duration of disk buildup and dissipation phases are measured for 70 outbursts, and we find that the average outburst takes about twice as long to dissipate as it does to build up in optical photometry. Our analysis hints that dissipation of the inner disk occurs relatively slowly for late-type Be stars.

description: The Aerodynamic Aerosol Classifier (AAC) is a novel instrument that selects aerosol particles based on their relaxation time or aerodynamic diameter. Additional theory and characterization is required to allow the AAC to accurately measure an aerosol's aerodynamic size distribution by stepping whilst connected to a particle counter (such as a Condensation Particle Counter, CPC). To achieve this goal, this study characterized the AAC transfer function (from 32 nm to 3 μm) using tandem AACs and comparing the experimental results to the theoretical tandem deconvolution. These results show that the AAC transmission efficiency is 2.6 to 5.1 times higher than a combined Krypton-85 radioactive neutralizer and Differential Mobility Analyzer (DMA), as the AAC classifies particles independent of their charge state. However, the AAC transfer function is 1.3 to 1.9 times broader than predicted by theory. Using this characterized transfer function, the theory to measure an aerosol's aerodynamic size distribution using an AAC and particle counter was developed. The transfer function characterization and stepping deconvolution were validated by comparing the size distribution measured with an AAC-CPC system against parallel measurements taken with a Scanning Mobility Particle Sizer (SMPS), CPC and Electrical Low Pressure Impactor (ELPI). The effects of changing AAC classifier conditions on the particle selected were also investigated and found to be small (<1.5%) within its operating range.

description: We present a public code to generate a mock galaxy catalog in redshift space assuming a log-normal probability density function (PDF) of galaxy and matter density fields. We draw galaxies by Poisson-sampling the log-normal field, and calculate the velocity field from the linearised continuity equation of matter fields, assuming zero vorticity. This procedure yields a PDF of the pairwise velocity fields that is qualitatively similar to that of N-body simulations. We check fidelity of the catalog, showing that the measured two-point correlation function and power spectrum in real space agree with the input precisely. We find that a linear bias relation in the power spectrum does not guarantee a linear bias relation in the density contrasts, leading to a cross-correlation coefficient of matter and galaxies deviating from unity on small scales. We also find that linearising the Jacobian of the real-to-redshift space mapping provides a poor model for the two-point statistics in redshift space. That is, non-linear redshift-space distortion is dominated by non-linearity in the Jacobian. The power spectrum in redshift space shows a damping on small scales that is qualitatively similar to that of the well-known Fingers-of-God (FoG) effect due to random velocities, except that the log-normal mock does not include random velocities. This damping is a consequence of non-linearity in the Jacobian, and thus attributing the damping of the power spectrum solely to FoG, as commonly done in the literature, is misleading.

description: The bounce solutions of self-interacting scalar fields coupled to gravity are studied using a semi-classical approach. We found that bounce solutions have a maximum required barrier curvature, in addition to the known minimum required barrier curvature. In particular, as the maximum barrier curvature is approached, the scale factor of the well-known Colemen-De Luccia (CDL) bounce solutions become divergent. Unlike the CDL or its more general oscillating bounce counterparts, this cannot be considered as a subset of the Hawking-Turok solution.

description: The number of potential job candidates and therefore, costs associated with their hiring, has grown significantly in the recent years. This is mainly due to both the complicated situation of the labour market and the increased geographical flexibility of employees. Some initiatives for making the e-Recruitment processes more efficient have notably improved the situation by developing automatic solutions. But there are still some challenges that remain open since traditional solutions do not consider semantic relations properly. This problem can be appropriately addressed by means of a sub discipline of knowledge management called semantic processing. Therefore, we overview the major techniques from this field that can play a key role in the design of a novel business model that is more attractive for job applicants and job providers.

description: We report the first observation of the magnon-polariton bistability in a cavity magnonics system consisting of cavity photons strongly interacting with the magnons in a small yttrium iron garnet (YIG) sphere. The bistable behaviors are emerged as sharp frequency switchings of the cavity magnon-polaritons (CMPs) and related to the transition between states with large and small number of polaritons. In our experiment, we align, respectively, the [100] and [110] crystallographic axes of the YIG sphere parallel to the static magnetic field and find very different bistable behaviors (e.g., clockwise and counter-clockwise hysteresis loops) in these two cases. The experimental results are well fitted and explained as being due to the Kerr nonlinearity with either positive or negative coefficient. Moreover, when the magnetic field is tuned away from the anticrossing point of CMPs, we observe simultaneous bistability of both magnons and cavity photons by applying a drive field on the lower branch.
