description: This paper presents an extension of recently published large signal model of peak limiting current mode controlled dc-dc converters by including an artificial ramp intended to provide the limit cycle stability into the model. The model was implemented and verified using computer simulation. Existence of an infinite number of discontinuous conduction modes has been observed, similar to the case when the artificial ramp is not applied. Boundaries between the modes as they depend on circuit parameters were analytically established, showing a reduction of the area covered by the discontinuous conduction modes. The analytically established boundaries were verified by simulation.

description: Rashba spin-orbit coupling appears in 2D systems lacking inversion symmetry, and causes the spin-splitting of otherwise degenerate energy bands into an upper and lower helicity band. In this paper, we explore how impurity scattering affects transport in the ultra-low-density regime where electrons are confined to the lower helicity band. A previous study has investigated the conductivity in this regime using a treatment in the first Born approximation. In this work, we use the full T-matrix to uncover new features of the conductivity. We first compute the conductivity within a semiclassical Boltzmann framework and show that it exhibits an unconventional density dependence due to the unusual features of the group velocity in the single particle dispersion, as well as quantized plateaus as a function of the logarithm of the electron density. We support this with a calculation using the Kubo formula and find that these plateaus persist in the full quantum theory. We suggest that this quantization may be seen in a pump-probe experiment.

Die Cuspis ist kurz, besteht eigentlich nur aus einem kurzen Stück der Lamellen mit zwei ungleichen Zähnen. Dabei ist der Außenzahn immer kurz, doch zugespitzt, der Innenzahn lang, von oben gesehen mit einer breiten Basis hell, von der Seite gesehen gleichmäßig breit, dunkel. Zwischen beiden Zähnen ist die Stelle wo das Lamellarhaar entspringt etwas erhöht. Der Intercuspidalzahn ist immer konisch, nie gerundet und dunkler gefärbt als die Lamellen bzw. die Cuspidalzähne. Er stellt eigentlich eine Verlängerung des Innensaumes der Lamellen dar. Manchmal ist an der Stelle, wo die Cuspides am nächsten stehen, eine Art Translamelle in Form eines breiten Querbalkens ausgebildet, so, daß der Zahn auf diesem zu stehen kommt. Nicht selten ist der Intercuspidalzahn auf dem Propodosoma angeheftet, da der Querbalken fehlt, die Lamellen aber mit ihrem Innensaum (Kante) auf das Propodosoma angeheftet sind (wie bei anderen L.). Die Größe des Zahnes ist verschieden, immer breiter als lang (siehe L. parvus Mih.).
Das Rostrum ist durch zwei schräg nach hinten und außen laufende Einschnitte in drei Lappen geteilt. Die Seitenlappen sind mit einem Innenzahn ausgerüstet, doch kann dieser auch fehlen, dann sind sie nur schwach eingebuchtet, der Mittellappen ist aber fast gerade oder schwach dreiwellig. Hinten ist eine immer dunkle Linie oder Leiste mit oder ohne Vorsprung.
Das Organum ist schalenförmig und schräg seitwärts geneigt. Die Spitze des Sensillus kaum länger als die Spindel und diese länger als der Basalteil. Die Grenzlinie ist geschlossen und vorne eingebuchtet.
Gefunden in Kärnten und um Lienz (Tristach, St. Johann i. W.).

description: The nature of a physical law is examined, and it is suggested that there may not be any fundamental dynamical laws. This explains the intrinsic indeterminism of quantum theory. The probabilities for transition from a given initial state to a final state then depends on the quantum geometry that is determined by symmetries, which may exist as relations between states in the absence of dynamical laws. This enables the experimentally well confirmed quantum probabilities to be derived from the geometry of Hilbert space, and gives rise to effective probabilistic laws. An arrow of time which is consistent with the one given by the second law of thermodynamics, regarded as an effective law, is obtained. Symmetries are used as the basis for a new proposed paradigm of physics. This gives rise naturally to the gravitational and gauge fields from the symmetry group of the standard model, and a general procedure for obtaining interactions from any symmetry group.

description: We have studied implications of the generic lopsided mass matrix of the charged leptons by taking the SU(5) GUT relation in the nearest-neighbor interaction (NNI) basis. We have found four interesting relations among the lepton mixings and the quark ones, which are independent of details of the model. These relations are discussed by using the experimental data. We have also discussed the relation between U_{e2} and U_{e3} incuding the contribution from the neutrino mass matrix. We have presented the probable value U_{e3}=0.05 \sim 0.16, which is independent of the solar neutrino solutions. The CP violating quantity J_{CP} is also discussed.

description: The vacuum polarization functions $Π(q^2)$ of charged and neutral gauge bosons which arise from top and bottom quark loops lead to important shifts in relations between electroweak parameters which can be measured with ever-increasing precision. The large mass of the top quark allows approximation of these functions through the first two terms of an expansion in $M_Z^2/M_t^2$. The first three terms of the Taylor series of $Π(q^2)$ are evaluated analytically up to order $\as^2$. The first two are required to derive the approximation, the third can be used to demonstrate the smallness of the neglected terms. The paper improves earlier results based on the leading term $\propto G_F M_t^2 \as^2$. Results for the subleading contributions to $\dr$ and the effective mixing angle $\sineff$ are presented.

Modelling and Simulation of the Nonlinear Dynamics of Arrays of Coupled Filaments for Robot Walkers

Subjects: metachronal Wave

description: This thesis project centers on modelling and simulation of the nonlinear dynamics of systems of filaments attached to a solid substrate that couples their motion. The geometry of the system is inspired by ubiquitous structures found in small organisms. These structures, called cilia, exhibit different types of organized coordinated patterns used for locomotion, among other functions. One notable type of coordination is called metachronal, which manifests through wave propagation across the filaments, and it is inherently related to motility and locomotion. The same type of wave phenomena are observed in larger organisms such as centipedes and millipedes, which use it for terrestrial locomotion. While there are many studies on cilia-inspired robot locomotion, they often focus on hydrodynamic coupling or magnetic actuation. This thesis introduces a model with mechanical coupling. The main objective of the thesis is to derive a mechanical model and to simulate it, creating the foundation for the systematic prediction of the emergence of coordinated patterns of the system. The ultimate goal for future work is to use the predictions to design controls for terrestrial locomotion systems for mobile autonomous robots capable of navigating across various terrains. The system we simulate consists of arrays of rigid filaments that are coupled through visco-elastic lumped elements at the base. These filaments emulate hair-like structures idealized as inverted pendulums, capturing certain characteristics of cilia-like structures that are relevant for the locomotion. Mechanical coupling is achieved through elastic springs and linear viscous dampers, creating a lumped-parameter model of the coupling base. The governing equations for the system are derived using Euler-Lagrange's formalism. In simulations, our primary objective is to examine coordinated patterns under diverse initial conditions. The evolution of the simulated system demonstrates a convergence towards a synchronized state. The study contributes to the exploration of bio-inspired approaches for developing robust terrestrial robot walkers capable of adaptive and efficient movement.

description: Recently the semileptonic decays $B\to X_s e^+ e^-$, $B\to X_s μ^+ μ^-$ in generic supersymmetric extensions of the Standard Model have been studied in ref.~\cite{noi}. In this talk I review the main points of this analysis. SUSY effects are parameterized using the mass insertion approximation formalism and differences with MSSM results are pointed out. Constraints on SUSY contributions coming from other processes ({\it e.g.} $b\to s \g$) are taken into account. Chargino and gluino contributions to photon and Z-mediated decays are computed and non-perturbative corrections are considered. We find that the integrated branching ratios and the asymmetries can be strongly modified. Moreover, the behavior of the differential Forward-Backward asymmetry remarkably changes with respect to the Standard Model expectation.

Malaconothrus monodactylus has been recorded from the British Isles on several occasions. Michael (1888) found it in moss at Cannock Chase, Staffordshire; Hull (1915) recorded it from mosses at Delamere, Cheshire; Halbert (1915) recorded it from moss on Clare Island and on Croaghpatrick, Co. Mayo; Wood (1967) recorded it from upland moorland, near Malham Tarn, North Yorkshire, and Behan-Pelletier and Hill (1983) recorded it from acid peat bog, Glenamoy, Co. Mayo. Hull (1916) also offered 'Scotland' as a locality. In the absence of original specimens the veracity of Hull's records cannot be confirmed. Indeed, a vial from the Hull Collection labelled ' N. monodactylus ' (from Hatchmere, Cheshire) was found to contain an adult and a juvenile Nanhermannia sp., and a Malaconothrus which, although too badly damaged for an authoritative identification, was not M. monodactylus.

description: The widespread adoption of technologies has made digital transformation relevant to almost every sector of the economy, including agriculture. Thanks to technologies such as the Internet of Things (IoT), the farming industry now has access to tools that enable a shift from precision agriculture to farming. Smart farming has progressed from precision agriculture, which relied on technologies like satellites and planes for precise product applications, such as pesticides. These improvements allowed for the collection of information and assisting farmers at a reduced cost. The research examined farming architecture systems and their different levels. It introduced commonly used machine learning models in agricultural data management. By applying mathematical methodologies, a simulation model was created to study the growth of crops, particularly focusing on cassava as the plant of interest. Additionally, various machine learning models were constructed and evaluated using the available data.

description: Novel member of polymetalloporphines, namely manganese polymetalloporphine of type I (pMnP-I) obtained by ion exchange from magnesium polyporphine of type I (pMgP-I) is reported for the first time and compared to its cobalt analogue (pCoP-I). Both polymer films have been obtained via two-step procedure: demetalation of the pMgP-I electrode film via its exposure to trifluoroacetic acid solution, resulting in formation of the metal-free polyporphine of type I (pH2P-I) followed by electrochemically induced incorporation of Co or Mn ions from the acetonitrile solution of cobalt and manganese perchlorates. A further oxidative transformation of pCoP-I, pMnP-I polymer films has led to the corresponding polyporphines of type II, pCoP-II and pMnP-II, possessing such unique features as condensed polymer structure with a very high density of active sites and high electronic conductivity within a very broad potential range including the one corresponding to the neutral (uncharged) state of the polymer matrix. Both polymers of type II also exhibit interesting electrocatalytic activity toward oxygen electroreduction in aqueous neutral (pH 6.7) and alkaline (pH 13) media which was evaluated under cyclic voltammetric and steady-state conditions. The results demonstrate that the efficiency (regardless of the electrolyte) of both polymetalloporphines is comparable to bare platinum electrode. The effect of annealing of polymer-modified electrodes on their catalytic properties has also been considered.

description: Given the importance of the fishing industry to the Newfoundland economy and identity, understanding the realities of fish work in the province allows for a deeper understanding of labour practices, safety regulations, and the health of the many fisheries the bolster that Newfoundland economy and identity. Initially designed to assess the working experiences of migrant workers on Canadian fishing boats, this thesis turns to domestic workers to unpack labour realties and address the potential of exploitative and abusive practices that help chart fishing among one of the most dangerous jobs in the world. This research took place in Newfoundland in October of 2022, where crew members, boat captains, their owners, and industry and union representatives were approached to gather work experiences and opinions on the broader regional fishing industry in the province. From these experiences, an assessment of how and if exploitative working conditions can be improved utilizes existing and proposed international labour conventions, understandings of unionization, and the political economy, to represent exploitative labour conditions along a continuum. The evolving and changing economic and environmental realities of fishing both globally and in eastern Canada highlight how an already risk-taking, masculine, and community focused industry lives with, is shaped by, and can work towards limiting, the more damaging forms of exploitation. This thesis utilizes qualitative data to inform its assessment of precarious labour realities at sea in the Newfoundland fishing industry to further advocate for the move towards regionalized and industry specific seafarer support mechanisms. Through promoting these mechanisms, such as a seafarer support centre and the ratification of the Work in Fishing Convention (C188), this research calls for Newfoundland's fishing industry to lead the way towards better practices nationally.

description: The rise of sauropodomorphs is still poorly understood due to the scarcity of well-preserved fossils in early Norian rocks. Here, we present an association of complete and exceptionally well-preserved dinosaur skeletons that helps fill that gap. They represent a new species, which is recovered as a member of a clade solely composed of Gondwanan Triassic taxa. The new species allows the definition of a set of anatomical changes that shaped sauropodomorph evolution along a period from 233 to 225 Ma, as recorded in the well dated Late Triassic beds of Brazil. In that time span, apart from achieving a more herbivorous diet, sauropodomorph dinosaurs increased their size in a ratio of 230% and their typical long neck was also established, becoming proportionally twice longer than those of basal taxa. Indeed, the new dinosaur is the oldest-known sauropodomorph with such an elongated neck, suggesting that the ability to feed on high vegetation was a key trait achieved along the early Norian. Finally, the clustered preservation mode of the skeletons represents the oldest evidence of gregarious behaviour among sauropodomorphs.
Strategies to cure numerical shock instability in HLLEM Riemann solver

Year: 2018

description: The HLLEM scheme is a popular contact and shear preserving approximate Riemann solver for cheap and accurate computation of high speed gasdynamical flows. Unfortunately this scheme is known to be plagued by various forms of numerical shock instability. In this paper we present various strategies to save the HLLEM scheme from developing such spurious solutions. A linear scale analysis of its mass and interface-normal momentum flux discretizations reveal that its antidiffusive terms, which are primarily responsible for resolution of linear wavefields, are inadvertently activated along a normal shock front due to numerical perturbations. These erroneously activated terms counteract the favourable damping mechanism provided by its inherent HLL-type diffusive terms and trigger the shock instability. To avoid this, two different strategies are proposed for discretization of these critical flux components in the vicinity of a shock: one that deals with increasing the magnitude of inherent HLL-type dissipation through careful manipulation of specific non-linear wave speed estimates while the other deals with reducing the magnitude of these critical antidiffusive terms. A linear perturbation analysis is performed to gauge the effectiveness of these cures and estimate von-Neumann type stability bounds on the CFL number arising from their use. Results from classic numerical test cases show that both types of modified HLLEM schemes are able to provide excellent shock stable solutions while retaining commendable accuracy on shear dominated viscous flows.

Biosorption by Green Alga Chlorella vulgaris for Decontamination of Pb(II) from Wasters at Near Benign Concentration

description: Lead ion, i.e., Pb(II), is one of the most toxic heavy metal ions (HMI) that constitutes a significant threat to aquatic ecosystems and human health. It is non-biodegradable and, therefore, could build up in human bodies to a harmful level via biomagnification and bioaccumulation, even when it exists at a very low level in the environment. Its presence in the environment is mainly due to human activities such as mining, burning fossil fuels, and industrial operations, which contaminate natural water sources through pathways such as precipitation of dust in the contaminated atmosphere, runoffs of contaminated soils, and discharge of contaminated wastewater. Corrosion of pipelines may also cause leakage of heavy metals into tap water. The levels of HMI, including Pb(II), in contaminated natural waterbodies are mostly at near-benign concentrations (10-100 ppb), which is harmful but very difficult to decontaminate with conventional methods. This study investigated the potential of utilizing growing green alga Chlorella vulgaris in removing Pb(II) from water sources contaminated with near-benign concentrations (10-100 ppb). The growth and behavior of C. vulgaris cells under Pb(II) exposure were examined. It was first established that the biosorption of Pb(II) by growing C. vulgaris in culture containing near-benign level Pb(II) was very similar to that of non-growing cells with short contact time. Then, biosorption tests were carried out with non-growing cells to analyze the effects of various factors such as pH, contact time, biomass concentration, and Pb(II) concentration. Results indicate that C. vulgaris exhibits promising biosorption abilities, with efficient removal of Pb(II) attributed mainly to surface adsorption mechanisms. PH played an important role in biosorption, with increasing pH enhancing biosorption in the tested range of pH 2.0 - pH 7.0. The rapid adsorption kinetics with the plateau achieved within 5 minutes contact time and the desorption of over 85.7% of lead from cells using EDTA buffer support the hypothesis that the biosorption of Pb(II) at near-benign levels is surface adsorption, which has been well reported for the biosorption of Pb(II) and other HMI by microalgae at high-level biosorption tests. Results of the study show that using C. vulgaris could effectively decontaminate Pb(II) contaminated water to meet drinking water standards within a well-defined operation window.

description: Targeted advertising is meant to improve the efficiency of matching advertisers to their customers. However, targeted advertising can also be abused by malicious advertisers to efficiently reach people susceptible to false stories, stoke grievances, and incite social conflict. Since targeted ads are not seen by non-targeted and non-vulnerable people, malicious ads are likely to go unreported and their effects undetected. This work examines a specific case of malicious advertising, exploring the extent to which political ads from the Russian Intelligence Research Agency (IRA) run prior to 2016 U.S. elections exploited Facebook's targeted advertising infrastructure to efficiently target ads on divisive or polarizing topics (e.g., immigration, race-based policing) at vulnerable sub-populations. In particular, we do the following: (a) We conduct U.S. census-representative surveys to characterize how users with different political ideologies report, approve, and perceive truth in the content of the IRA ads. Our surveys show that many ads are "divisive": they elicit very different reactions from people belonging to different socially salient groups. (b) We characterize how these divisive ads are targeted to sub-populations that feel particularly aggrieved by the status quo. Our findings support existing calls for greater transparency of content and targeting of political ads. (c) We particularly focus on how the Facebook ad API facilitates such targeting. We show how the enormous amount of personal data Facebook aggregates about users and makes available to advertisers enables such malicious targeting.

description: We examine isospin breaking in the nucleon wave functions due to the $u - d$ quark mass difference and the Coulomb interaction among the quarks, and their consequences on the nucleon electroweak form factors in a nonrelativistic constituent quark model. The mechanically induced isospin breaking in the nucleon wave functions and electroweak form factors are exactly evaluated in this model. We calculate the electromagnetically induced isospin admixtures by using first-order perturbation theory, including the lowest-lying resonance with nucleon quantum numbers but isospin 3/2. We find a small ($\leq 1\%$), but finite correction to the anomalous magnetic moments of the nucleon stemming almost entirely from the quark mass difference, while the static nucleon axial coupling remains uncorrected. Corrections of the same order of magnitude appear in charge, magnetic, and axial radii of the nucleon. The correction to the charge radius in this model is primarily isoscalar, and may be of some significance for the extraction of the strangeness radius from e.g. elastic forward angle parity violating electron-proton asymmetries, or elastic ${}^4He({\vec e},e')$ experiments.

description: The escalating challenge of antibiotic resistance in clinical settings underscores the urgent need for novel antimicrobial strategies. This thesis presents a concerted effort to address this crisis by targeting bacterial metabolism, specifically the biotin biosynthetic pathway. Biotin, a crucial vitamin for bacterial growth, is synthesized through a pathway involving the enzyme BioA. Our research focuses on MAC13772, a synthetic acetohydrazide identified as a potential inhibitor of BioA, which plays a pivotal role in this pathway. Originating from SAR studies at McMaster University, MAC13772 exhibited promising antibacterial properties, albeit with limitations in potency and potential toxicity that necessitated further optimization. The primary objective of this study was to enhance the antibacterial efficacy of MAC13772 against Gram-negative pathogens through structural modification and optimization. A comprehensive series of analogs were synthesized, aiming to overcome the limitations of MAC13772 by improving its potency and metabolic stability. Notably, a trifluoromethyl derivative emerged as significantly more potent against Acinetobacter baumannii, achieving a four-fold increase in efficacy. Moreover, dichloro-substituted analogues demonstrated a remarkable improvement in inhibitory concentration values against BioA, with up to a 90-fold enhancement. Additionally, a benzimidazole derivative was identified for its superior metabolic stability in liver microsomes, indicating a potential for increased in vivo efficacy. This research not only advances our understanding of the biotin biosynthetic pathway as a viable target for antibiotic intervention but also highlights the successful application of SAR studies in the development of more potent and stable antibacterial agents. By addressing the pharmacokinetic shortcomings of MAC13772 and its analogs, this work lays a foundational step towards the identification of new antibacterial drugs capable of combating the growing threat of drug-resistant bacteria.

The Supersymmetric Flavor Problem
Creators: name: Dimopoulos, Savas

Publisher: name: arXiv
Year: 1995
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The supersymmetric $SU(3)\times SU(2)\times U(1)$ theory with minimal particle content and general soft supersymmetry breaking terms has 110 physical parameters in its flavor sector: 30 masses, 39 real mixing angles and 41 phases. The absence of an experimental indication for the plethora of new parameters places severe constraints on theories posessing Planck or GUT-mass particles and suggests that theories of flavor conflict with naturalness. We illustrate the problem by studying the processes $μ\rightarrow e + γ$ and $K^0 - \bar{K}^0$ mixing which are very sensitive probes of Planckian physics: a single Planck mass particle coupled to the electron or the muon with a Yukawa coupling comparable to the gauge coupling typically leads to a rate for $μ\rightarrow e + γ$ exceeding the present experimental limits. A possible solution is that the messengers which transmit supersymmetry breaking to the ordinary particles are much lighter than $M_{\rm Planck}$.

description: Implementing quantum key distribution in existing optical telecommunication infrastructure requires the employment of appropriate spatial, spectral, and temporal filtering to achieve high tolerance to noise from classical optical signals present in fibre networks. Electronic temporal filtering may be limited by the nanosecond-scale timing jitter of typical single-photon detectors; this requires us to use faster physical processes to rapidly gate the desired optical signal, while rejecting random noise photons arriving outside of a narrow passing window. In this work, we use ultrashort optical pulses to implement a Kerr switch in a 1-metre length of single-mode fibre to perform all-optical temporal filtering of noise in a telecom-wavelength quantum channel. Using our switch, we demonstrate 2.4-ps temporal gating of 1.3 µm-wavelength signal photons with a near-unity switching efficiency of 98.77 ± 0.01%. We also show that our switch can be used as an effective ultrafast temporal filter capable of reducing noise introduced into a quantum channel by up to 18.2 dB.

An Examination of How Donald Trump's Charismatic Leadership and Charismatic Rhetoric Uses Twitter to Bond with his Followers

description: Trump's tumultuous presidency has been described as far-right through the use of discriminatory and nationalist talking points to prey upon the fears of conservative citizens in the US. He has also been described as charismatic, but research has not focused upon how he used Twitter to convey his charismatic leadership and rhetoric to the public. This thesis seeks to examine how Donald Trump's use of charismatic leadership and charismatic rhetoric influence his use of Twitter and how he interacts with his followers. I analyze Trump's tweets between May 25th, 2020, until January 8th, 2021, as two significant events (the Black Lives Matter protests and the 2020 US presidential election) occurred during this time that help shape his presidency. I found that through examining Trump's tweets, it is shown that he promotes a far-right brand of loyalty that supports the suppression of anybody that opposes him.

description: 4. Liacarus parvus Mih. (Abb. 4)
Auch bei dieser Art reichen die Lamellen über das Rostrum hinaus. Ihre Cuspides sind aber viel kürzer und breiter als bei der vorigen Art. Der Außenzahn ist fast gerade nach vorne gerichtet und ist viel kürzer als der Innenzahn; zwischen beiden Cuspides ist ein breiter, gerundeter Zapfen im breiten Intercuspidalspalt. Die Verbindungslinie der Lamellen ist bogig eingebuchtet.
Das Rostrum ist dreilappig, doch sind die Einschnitte schräg nach außen gerichtet, wie bei L. coracinus, dem die Art stark ähnelt. Doch sind die Lappen am Ende gerundet. Der Mittellappen hat einen geraden Aufsatz. Hinter ihm ist ein kurzer, nicht die ganze Breite einnehmender heller Spalt (bei L. coracinus dunkel, bis schwarz). Am Hysterosoma sind kurze Börstchen.
Von L. coracinus, dem die Art, wie erwähnt stark ähnelt, unterscheidet sich: durch den gerundeten Zapfen im Intercuspidalspalt, durch die helle, bogige Stelle hinter dem Mittellappen und durch plumpere, d. h. breitere Lamellen. (Weitere Unterscheidungsmerkmale sind aus dem oben genannten Beitrag zu erlesen).

description: Resonant systems emerge as weakly nonlinear approximations to problems with highly resonant linearized perturbations. Examples include nonlinear Schroedinger equations in harmonic potentials and nonlinear dynamics in Anti-de Sitter spacetime. The classical dynamics within this class of systems can be very rich, ranging from fully integrable to chaotic as one changes the values of the mode coupling coefficients. Here, we initiate a study of quantum infinite-dimensional resonant systems, which are mathematically a highly special case of two-body interaction Hamiltonians (extensively researched in condensed matter, nuclear and high-energy physics). Despite the complexity of the corresponding classical dynamics, the quantum version turns out to be remarkably simple: the Hamiltonian is block-diagonal in the Fock basis, with all blocks of varying finite sizes. Being solvable in terms of diagonalizing finite numerical matrices, these systems are thus arguably the simplest interacting quantum field theories known to man. We demonstrate how to perform the diagonalization in practice, and study both numerical patterns emerging for the integrable cases, and the spectral statistics, which efficiently distinguishes the special integrable cases from generic (chaotic) points in the parameter space. We discuss a range of potential applications in view of the computational simplicity and dynamical richness of quantum resonant systems.
