description: Existing smart composite piezoelectric beam models in the literature mostly ignore the electro-magnetic interactions and adopt the linear elasticity theory. However, these interactions substantially change the controllability and stabilizability at the high frequencies, and linear models fail to represent and predict the governing dynamics since mechanical nonlinearities are pronounced in certain applications such as energy harvesting. In this paper, first, a consistent variational approach is used by considering nonlinear elasticity theory to derive equations of motion for a single-layer piezoelectric beam with and without the electromagnetic interactions (fully dynamic and electrostatic). This modeling strategy is extended for the three-layer piezoelectric smart composites by adopting the two widely-accepted sandwich beam theories. For both single-layer and three-layer models, the resulting infinite dimensional equations of motion can be formulated in the state-space form. It is observed that the fully dynamic nonlinear models are unbounded boundary control systems (same in linear theory) ${\bf \dot y}(t)=(\mathcal A +\mathcal N) {\bf y} (t) + \mathcal B u(t)$, the electrostatic nonlinear models are unbounded bilinear control systems ${\bf \dot y}(t)=(\mathcal A +\mathcal N){\bf y} (t) + (\mathcal B_1+ \mathcal B_2 {\bf y}) u(t)$ in sharp contrast to the linear theory. Finally, we propose $\mathcal B^*-$type feedback controllers to stabilize the single piezoelectric beam models. The filtered semi-discrete Finite Difference approximations is adopted to illustrate the findings.

On the von Neumann capacity of noisy quantum channels

description: We discuss the capacity of quantum channels for information transmission and storage. Quantum channels have dual uses: they can be used to transmit known quantum states which code for classical information, and they can be used in a purely quantum manner, for transmitting or storing quantum entanglement. We propose here a definition of the von Neumann capacity of quantum channels, which is a quantum mechanical extension of the Shannon capacity and reverts to it in the classical limit. As such, the von Neumann capacity assumes the role of a classical or quantum capacity depending on the usage of the channel. In analogy to the classical construction, this capacity is defined as the maximum von Neumann mutual entropy processed by the channel, a measure which reduces to the capacity for classical information transmission through quantum channels (the "Kholevo capacity") when known quantum states are sent. The quantum mutual entropy fulfills all basic requirements for a measure of information, and observes quantum data-processing inequalities. We also derive a quantum Fano inequality relating the quantum loss of the channel to the fidelity of the quantum code. The quantities introduced are calculated explicitly for the quantum "depolarizing" channel. The von Neumann capacity is interpreted within the context of superdense coding, and an "extended" Hamming bound is derived that is consistent with that capacity.

description: We investigate quench dynamics of spin ice after removal of a strong magnetic field along the [100] crystal direction, using Monte Carlo simulations and theoretical arguments. We show how the early-time relaxation of the magnetization can be understood in terms of nucleation and growth of strings of flipped spins, in agreement with an effective stochastic model that we introduce and solve analytically. We demonstrate a crossover at longer times to a regime dominated by approximately isotropic clusters, which we characterize in terms of their morphology, and present evidence for a percolation transition as a function of magnetization.

description: This work examines the labor conditions experienced by a primarily Latina/o immigrant labor force following the massive devastation in the Deep-South in the wake of Hurricanes Katrina and Rita. I argue that immigrant workers have been targeted as an exploitable workforce by the state, multinational corporations, and contractors to perform the difficult and dangerous work of clean-up and rebuilding in the affected region. The recruitment of large numbers of primarily Latino men to the Deep South has resulted in a demographic shift throughout the entire South. The movement of immigrant men has initiated an increase in the number of immigrant women entering the work force in the Middle South, creating diasporas in immigrant communities. An investigation of legal advocacy by the Southern Poverty Law Center exposes the extreme conditions and practices of labor exploitation employed by corporations and contractors in the rebuilding of the hurricane-affected regions. Also discussed are the impacts to the labor force throughout the entire South, with particular attention to legal advocacy needs of immigrant women. The legal advocacy of the Southern Poverty Law Center serves as a model in the protection of the human, civil, and labor rights of immigrant workers.

description: Nittka gave an efficient criterion on a form defined on $L_2(Ω)$ which implies that the associated semigroup is $L_p$-invariant for some given $p \in (1,\infty)$. We extend this criterion to the Hilbert space valued~$L_2(Ω,H)$. As an application we consider elliptic systems of pure second order. Our main result shows that the induced semigroup is $L_p$-contractive for all $p \in [p_-,p_+]$ for some $1 < p_- < 2 < p_+ < \infty$.

description: Fluidisation is the process by which the weight of a bed of particles is supported by a gas flow passing through it from below. When fluidised materials flow down an incline, the dynamics of the motion differ from their non-fluidised counterparts because the granular agitation is no longer required to support the weight of the flowing layer. Instead, the weight is borne by the imposed gas flow and this leads to a greatly increased flow mobility. In this paper, a framework is developed to model this two phase motion by incorporating a kinetic theory description for the particulate stresses generated by the flow. In addition to calculating numerical solutions for fully developed flows, it is shown that for sufficiently thick flows there is often a local balance between the production and dissipation of the granular temperature. This phenomenon permits an asymptotic reduction of the full governing equations and the identification of a simple state in which the volume fraction of the flow is uniform. The results of the model are compared with new experimental measurements of the internal velocity profiles of steady granular flows down slopes. The distance covered with time by unsteady granular flows down slopes and along horizontal surfaces and their shapes are also measured and compared with theoretical predictions developed for flows that are thin relative to their streamwise extent. For the horizontal flows, it was found that resistance from the sidewalls was required in addition to basal resistance to capture accurately the unsteady evolution of the front position and the depth of the current and for situations in which side-wall drag dominates, similarity solutions are found for the experimentally-measured motion.

One consists of W-balls nearly identical to the glueball spectrum of the pure gauge theory, the other of bound states of scalars.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: The nitrogen-vacancy (NV) center occurs in GaAs bulk crystals doped or implanted with nitrogen. The local vibration of nitrogen gives rise to a sharp infrared absorption band at 638 cm$^{-1}$, exhibiting a fine structure due to the different masses of neighboring $^{69}$Ga and $^{71}$Ga host isotopes. Piezospectroscopic investigations in the crystallographic <100> direction prove that the center has C$_\text{3v}$ point symmetry, which is weakly perturbed by the isotope effect. The stress-induced shifts of some band components show an unusual non-linear behavior that can be explained by coupling between the isotope and the stress splitting. First-principles density-functional theory calculations are in full accordance with the experiments and confirm the C$_\text{3v}$ symmetry, caused by relaxation of the nitrogen atom from the anion lattice site towards the nearest-neighbor Ga plane. The NV center in GaAs is structurally analogous to the same center in diamond. The $-3$ charge state is most stable for nearly all Fermi-level positions.

description: The dynamical equation of quantum mechanics are rewritten in form of dynamical equations for the measurable, positive marginal distribution of the shifted, rotated and squeezed quadrature introduced in the so called "symplectic tomography". Then the possibility of a purely classical description of a quantum system as well as a reinterpretation of the quantum measurement theory is discussed and a comparision with the well known quasi-probabilities approach is given. Furthermore, an analysis of the properties of this marginal distribution, which contains all the quantum information, is performed in the framework of classical probability theory. Finally examples of harmonic oscillator's states dynamics are treated.

description: We investigate the thermal expansion and superconducting properties of a CuAl2-type (tetragonal) superconductor CoZr2 under high pressures. We perform high-pressure synchrotron X-ray diffraction in a pressure range of 2.9 GPa < P < 10.4 GPa and discover that CoZr2 exhibits volumetric negative thermal expansion under high pressures. Although the uniaxial positive thermal expansion (PTE) along the a-axis is observed under ambient pressure, that is suppressed by pressure, while the large uniaxial negative thermal expansion (NTE) along the c-axis is maintained under the pressure regime. As a result of a combination of the suppressed uniaxial PTE along the a-axis and uniaxial NTE along the c-axis, volumetric negative thermal expansion is achieved under high pressure in CoZr2. The mechanisms of volumetric NTE would be based on the flexible crystal structure caused by the soft Co-Co bond as seen in the iso-structural compound FeZr2, which exhibits uniaxial NTE along the c-axis. We also perform high-pressure electrical resistance measurements of CoZr2 to confirm the presence of superconductivity under the examined pressure regime in the range of 0.03 GPa < P < 41.9 GPa. We confirm the presence of superconductivity under all pressures and observe dome-like shape pressure dependence of superconducting transition temperature. Because of the coexistence of two phenomena, which are volumetric NTE and superconductivity, in CoZr2 under high pressure, the coexistence would be achievable under ambient pressure by tuning chemical compositions after our present observation.

description: A key part of implementing high-level languages is providing built-in and default data structures. Yet selecting good defaults is hard. A mutable data structure's workload is not known in advance, and it may shift over its lifetime - e.g., between read-heavy and write-heavy, or from heavy contention by multiple threads to single-threaded or low-frequency use. One idea is to switch implementations adaptively, but it is nontrivial to switch the implementation of a concurrent data structure at runtime. Performing the transition requires a concurrent snapshot of data structure contents, which normally demands special engineering in the data structure's design. However, in this paper we identify and formalize an relevant property of lock-free algorithms. Namely, lock-freedom is sufficient to guarantee that freezing memory locations in an arbitrary order will result in a valid snapshot. Several functional languages have data structures that freeze and thaw, transitioning between mutable and immutable, such as Haskell vectors and Clojure transients, but these enable only single-threaded writers. We generalize this approach to augment an arbitrary lock-free data structure with the ability to gradually freeze and optionally transition to a new representation. This augmentation doesn't require changing the algorithm or code for the data structure, only replacing its datatype for mutable references with a freezable variant. In this paper, we present an algorithm for lifting plain to adaptive data and prove that the resulting hybrid data structure is itself lock-free, linearizable, and simulates the original. We also perform an empirical case study in the context of heating up and cooling down concurrent maps.

description: Frustrated magnets with degenerate ground states exhibit exotic ground states and rich phase structures when perturbations and/or thermal fluctuations lift the degeneracy. In two-dimensional models with short-range interactions, continuous symmetries cannot spontaneously break at finite temperatures, leading to the suppression of conventional magnetic long-range ordering (LRO). In this paper, we numerically study the classical $J_1$-$J_2$ $XY$ antiferromagnet on the kagome lattice as a prototype model of such frustrated magnets, where $J_2$ denotes the next-nearest-neighbor exchange interaction. We map out the $J_2$-$T$ phase diagram of this model employing extensive classical Monte Carlo (MC) simulations. The obtained phase diagram features Berezinskii-Kosterlitz-Thouless (BKT) transitions of $q=0$, $\sqrt{3}\times\sqrt{3}$ magnetic orders, and octupole orders, in addition to finite-temperature phase transitions of both ferrochiral and antiferrochiral long-range orders. Additionally, we find a non-trivial first-order transition for antiferromagnetic $J_2/J_1 < 0$. The origin of this transition is discussed in the context of non-local loop structures present in local $120^\circ$ spin structures.

description: Doping is a common route to reducing nanowire transistor on-resistance but has limits. High doping level gives significant loss in gate performance and ultimately complete gate failure. We show that electrolyte gating remains effective even when the Be doping in our GaAs nanowires is so high that traditional metal-oxide gates fail. In this regime we obtain a combination of sub-threshold swing and contact resistance that surpasses the best existing p-type nanowire MOSFETs. Our sub-threshold swing of 75 mV/dec is within 25% of the room-temperature thermal limit and comparable with n-InP and n-GaAs nanowire MOSFETs. Our results open a new path to extending the performance and application of nanowire transistors, and motivate further work on improved solid electrolytes for nanoscale device applications.

Interaction of 157-nm excimer laser light with fused silica, polytertrafluoroethylene and calcium fluoride
Creators: name: George, Sharon Rose
Publisher: name: Washington State University
Year: 2010
Subjects: Lasers in physics

description: Emission of positive ions, neutral atoms and molecules and negative ions was observed during 157-nm irradiation of fused silica. Positive ion emission from fused Silica is best explained by a hybrid mechanism involving (a) excitation of an antibonding chemical state (Menzel-Gomer-Redhead mechanism) and (b) acceleration of the positive ion by repulsive electrostatic forces due to the photoionization of nearby electron traps. Neutral emission results from the absorption of single 157 nm photons that cleave strained bonds to produce defects that subsequently diffuse to the surface. There then react with dangling bonds to release neutral atoms and molecules. Negative ions are created after the laser pulse, by electron attachment to the neutral particles. Time- and mass-resolved measurements on neutral particles emitted PTFE during exposure to 157-nm laser radiation. We observe neutral (CF2)N radicals for all N up to the limit of our mass filter (N = 6). These radicals are emitted directly from the surface with high kinetic energies of about 0.6 eV of the fastest (CF2)N radicals consistent with photochemical scission of the polymer backbone. A great majority of emitted material is in the form of heavier fragments ranging from 300 to 2000 amu. The presence of heavy and light particles in the cloud of emitted particles gives rise to some unique behavior in the way it expands. The trajectories of the heaviest fragments are preferentially directed at large angles away from the surface normal-- often nearly parallel to the substrate surface. This behavior is due to density and pressure gradients associated with the Gaussian intensity profile of the laser beam. Transient absorption was observed in Calcium Fluoride during 157-nm irradiation with peaks at 153 nm, 220 nm and 375 nm under 157-nm irradiation due to the Hs -- center, Ca1+ interstitial and the F-center respectively. Capture of a hole by Hs -- center, Ca1+ interstitial destroys the absorption and trapping of an electron at Hi 0 center and the Ca2+ interstitial reinduces absorption. Aggregation of F-centers to form M-centers leads to loss of absorption at 375 nm and the dissociation of the M-center when irradiation is restored re-induces absorption.

Effects of anthropogenic disturbance on landscape ecology of cougars

Subjects: Puma -- Ecology

description: Anthropogenic disturbance in the form of hunting and human landscape alterations have extensive effects on cougar populations. I analyzed the effects of hunting and related immigration on the social organization of two independent populations of cougars; a source population with low hunting mortality (11%) and a 12% emigration rate, and a sink population with high mortality (24%) and a 13% immigration rate. I compared home range size, 2-dimensional home range overlap, and 3-dimensional utilization distribution overlap index (UDOI) between annual cougar home ranges. Male cougars in the heavily hunted area had 2-3 times larger home ranges, and 2-dimensional and 3-dimensional UDOI overlap-indicating a difference in the social structure in the high mortality area. Females showed no difference in home range size and overlap of home range areas between study populations. Traditional closed population methods to estimate density may over-estimate numbers of carnivores. I used cougar home range size and overlap to model total (closed) and proportional (open) densities within the 99% composite female range for two sampling areas in Washington. These simulations suggest that traditional closed population estimates may more than double or triple estimates of density and population size. The proportion of time spent by territorial animals within a sampling area should be considered when calculating densities of wide-ranging, territorial carnivores. Understanding the ecology of how cougars respond to human development aids in landscape planning and minimizes negative interactions. I analyzed sex and seasonal differences in use of human occupied areas and identified cumulative percentage of cougar utilization for distance to structures and density of human development. There were no differences in habitat use between sexes. Cougars used lower elevations and steeper slopes during winter, and expanded into higher elevation areas with greater canopy closure during summer. Cougar response to density of human structures was equally negative for both seasons. Only 5% of cougar habitat use occurs in areas where density of human structures exceeds 19.6 structures/km2. I found cougars utilized areas > than 240 m from structures 95% of the time in winter, and > 340 m from structures during summer.

description: We describe a number of aspects in our attempt to construct an approximately perfect lattice action for QCD. Free quarks are made optimally local on the whole renormalized trajectory and their couplings are then truncated by imposing 3-periodicity. The spectra of these short ranged fermions are excellent approximations to continuum spectra. The same is true for free gluons. We evaluate the corresponding perfect quark-gluon vertex function, identifying in particular the ``perfect clover term''. First simulations for heavy quarks show that the mass is strongly renormalized, but again the renormalized theory agrees very well with continuum physics. Furthermore we describe the multigrid formulation for the non-perturbative perfect action and we present the concept of an exactly (quantum) perfect topological charge on the lattice.

description: This dissertation examines the factors affecting consumer choice in education and health care. The first study relates to education choice in considering the value of a community college compared to a four-year university. Community colleges are less expensive, so a student might choose to attend community college for the first two years of a baccalaureate degree. However, there is a concern that the quality of education at a community college is lower. The first paper investigates whether students who take introductory macroeconomics and microeconomics courses at a community college perform as well as students taking the introductory sequence at a four-year university when the rigor of instruction is held constant. This study estimates a production function with correction for students dropping the course using a Heckman two-step process to determine which variables affect student performance. In the second paper, data from the National Director's Cup is used to investigate whether success in athletics affects the quality and quantity of applications an educational institution receives. Many college-bound high school students choose which university to attend based on a collection of institutional attributes such as academic quality, tuition, financial aid and overall success in athletics. Although athletics may not influence enrollments, applications or test scores, there is evidence that overall athletic success influences the premium that public universities charge their out-of-state students on tuition. Lastly, individuals who become ill must choose what type of primary care provider to utilize. In the third paper, data from the National Health Interview Survey is used to investigate whether individuals prefer to use clinics, doctor's offices or emergency rooms for their source of health care. Results indicated that most people preferred to have a regular doctor, but the absence / loss of health insurance, lower income and lower education levels caused people to use clinics or emergency rooms as their primary source of care.

description: The Micius satellite is the pioneering initiative to demonstrate quantum teleportation, entanglement distribution, quantum key distribution (QKD), and quantum-secured communications experiments at the global scale. In this work, we report on the results of the 600-mm-aperture ground station design which has enabled the establishment of a quantum-secured link between the Zvenigorod and Nanshan ground stations using the Micius satellite. As a result of a quantum communications session, an overall sifted key of 2.5 Mbits and a total final key length of 310 kbits have been obtained. We present an extension of the security analysis of the realization of satellite-based QKD decoy-state protocol by taking into account the effect of the detection-efficiency mismatch for four detectors. We also simulate the QKD protocol for the satellite passage and by that validate our semi-empirical model for a realistic receiver, which is in good agreement with the experimental data. Our results pave the way to the considerations of realistic imperfection of the QKD systems, which are important in the context of their practical security.

description: Ozsvath and Szabo have defined a knot concordance invariant tau that bounds the 4-ball genus of a knot. Here we discuss shortcuts to its computation. We include examples of Alexander polynomial one knots for which the invariant is nontrivial, including all iterated untwisted positive doubles of knots with nonnegative Thurston-Bennequin number, such as the trefoil, and explicit computations for several 10 crossing knots. We also note that a new proof of the Slice-Bennequin Inequality quickly follows from these techniques.

description: We present a theory for the generation of mesoscale ($kr_{g}\ll 1$, where $r_{g}$ is the cosmic ray gyroradius) magnetic fields during diffusive shock acceleration. The decay or modulational instability of resonantly excited Alfven waves scattering off ambient density perturbations in the shock environment naturally generates larger scale fields. For a broad spectrum of perturbations, the physical mechanism of energy transfer is random refraction, represented by diffusion of Alfven wave packet in $k-$space. The scattering field can be produced directly by the decay instability or by the Drury instability, a hydrodynamic instability driven by the cosmic ray pressure gradient. This process is of interest to acceleration since it generates waves of longer wavelength, and so enables the confinement and acceleration of higher energy particles. This process also limits the intensity of resonantly generated turbulent magnetic field on $r_{g}$ scales.

description: One-carbon (C1) metabolism is crucial to all living organisms. Tetrahydrofolate (H4PteGlun) -bound C1 units are needed in biosynthesis of purines, thymidylate, methionine, and N-formylmethionine, in the methylation of DNA, proteins, and phospholipids, and in biosynthesis of important plant secondary metabolites such as lignin, alkaloids, and betaines. Folates can only be synthesized de novo by plants and prokaryotes. Folate deficiency in humans has been linked to cardiovascular disease and cancer. To fight the problem of folate deficiency, wheat products have been fortified with synthetic folic acid. Dietary folate intake could also be increased by consuming folate-enriched plants; this could potentially be accomplished by engineering C1 metabolism. Serine hydroxymethyltransferase (SHMT) catalyzes reversible conversion of H4PteGlun and serine to 5,10-CH2-H4PteGlun and glycine and is one of the three enzymes that derivatize folates with C1 units. Understanding of SHMT features such as subcellular localization and kinetic properties for polyglutamylated H4PteGlun is necessary groundwork for plant C1 engineering. However, such knowledge is still lacking although SHMTs from several plant species have been studied in the past. Sequencing of the Arabidopsis genome revealed seven SHMTs predicted to be localized in mitochondria, plastids, the cytosol, and the nuclei. As a part of the effort to investigate all seven SHMTs in Arabidopsis, this study presents the first report on the characterization of a putative plastid SHMT (AtSHMT3). The localization of AtSHMT3 in plastids was verified with GFP fusions. Additionally, the presence of SHMT and 10-formyltetrahydrofolate synthetase in plastids of pea and barley was demonstrated. In order to assay SHMT at low concentrations of H4PteGlun, we developed a sensitive HPLC-based fluorometric assay. By using this HPLC assay, we obtained kinetic parameters for H4PteGlun=1-8 showing that AtSHMT3 has increased substrate affinity and catalytic efficiency as n grows from 1 to 8. This work also showed that both 5-CH3-H4PteGlu1&5 and 5-HCO-H4PteGlu1&5 inhibit AtSHMT3-catalyzed hydroxymethyl-group transfer from serine to H4PteGlu6 with the pentaglutamylated inhibitors being more effective. Calculations revealed that these pentaglutamylated inhibitors could lead to little reduction in AtSHMT3 activity under estimated folate concentrations in plastids.

description: Inspired by the recent discovery of a successive evolutions of electronically ordered states, we present a self-consistent theoretical analysis that treats the interactions responsible for the chiral charge order and superconductivity on an equal footing. It is revealed that the self-consistent theory captures the essential features of the successive temperature evolutions of the electronic states from the high-temperature ``triple-$Q$" $2\times 2$ charge-density-wave state to the nematic charge-density-wave phase, and finally to the low-temperature superconducting state coexisting with the nematic charge density wave. We provide a comprehensive explanation for the temperature evolutions of the charge ordered states and discuss the consequences of the intertwining of the superconductivity with the nematic charge density wave. Our findings not only account for the successive temperature evolutions of the ordered electronic states discovered in experiments but also provide a natural explanation for the two-fold rotational symmetry observed in both the charge-density-wave and superconducting states. Moreover, the intertwining of the superconductivity with the nematic charge density wave order may also be an advisable candidate to reconcile the divergent or seemingly contradictory experimental outcomes regarding the superconducting properties.

description: We theoretically investigate a two-dimensional decorated honeycomb lattice framework to realize a second-order topological magnon insulator (SOTMI) phase featuring distinct corner-localized modes. Our study emphasizes the pivotal role of spin-magnon mapping in characterizing bosonic topological properties, which exhibit differences from their fermionic counterparts. We employ a symmetry indicator topological invariant to identify and characterize this SOTMI phase, particularly for systems respecting time-reversal and ${\sf{C}}_6$ rotational symmetry. Using a spin model defined on a honeycomb lattice geometry, we demonstrate that introducing ``\textit{kekulé}'' type distortions yields a topological phase. In contrast, ``\textit{anti-kekulé}'' distortions result in a non-topological magnonic phase. The presence of kekulé distortions manifests in two distinct topologically protected bosonic corner modes - an \textit{intrinsic} and a \textit{pseudo}, based on the specific edge terminations. On the other hand, anti-kekulé distortions give rise to \SW{\textit{Tamm/Shockley}} type bond-localized boundary modes, which are non-topological and reliant on particular edge termination. We further investigate the effects of random out-of-plane exchange anisotropy disorder on the robustness of these bosonic corner modes. The distinction between SOTMIs and their fermionic counterparts arises due to the system-specific magnonic onsite energies, a crucial feature often overlooked in prior literature. Our study unveils exciting prospects for engineering higher-order topological phases in magnon systems and enhances our understanding of their unique behavior within decorated honeycomb lattices.
