AbstractIn this work we present a simple transfer-matrix based modeling tool for arbitrarily layered stacks of resonant plasmonic metasurfaces interspersed with dielectric and metallic multilayers. We present the application of this model by analyzing three seminal problems in nanophotonics. These are the scenario of perfect absorption in plasmonic Salisbury screens, strong coupling of microcavity resonances with the resonance of plasmon nano-antenna metasurfaces, and the hybridization of cavities, excitons and metasurface resonances.

"Tunable Fano Resonance and Enhanced Sensing in a Simple Au/TiO2 Hybrid Metasurface." Nanomaterials 10, no. 4 (April 5, 2020): 687. http://dx.doi.org/10.3390/nano10040687.
We investigate Fano resonances and sensing enhancements in a simple Au/TiO2 hybrid metasurface through the finite-different time-domain (FDTD) simulation and coupled mode theory (CMT) analysis. The results show that the Fano resonance in the proposed simple metasurface is caused by the destructive interaction between the surface plasmon polaritons (SPPs) and the local surface plasmon resonances (LSPRs), the quality factor and dephasing time for the Fano resonance can be effectively tuned by the thickness of Au and TiO2 structures, the length of each unit in x and y directions, as well as the structural defect. In particular, single Fano resonance splits into multiple Fano resonances caused by a stub-shaped defect, and multiple Fano resonances can be tuned by the size and position of the stub-shaped defect. Moreover, we also find that the sensitivity in the Au/TiO2 hybrid metasurface with the stub-shaped defect can reach up to 330 nm/RIU and 535 nm/RIU at the Fano resonance 1 and Fano resonance 2, which is more than three times as sensitive in the Au/TiO2 hybrid metasurface without the stub-shaped defect, and also higher than that in the TiO2 metasurface reported before. These results may provide further understanding of Fano resonances and guidance for designing ultra-high sensitive refractive index sensors.

AbstractNanoshells, concentric nanoparticles consisting of a dielectric core and a metallic shell, are simple spherical nanostructures with unique, geometrically tunable optical resonances. As with all metallic nanostructures, their optical properties are controlled by the collective electronic resonance, or plasmon resonance, of the constituent metal, typically silver or gold. In striking contrast to the resonant properties of solid metallic nanostructures, which exhibit only a weak tunability with size or aspect ratio, the optical resonance of a nanoshell is extraordinarily sensitive to the inner and outer dimensions of the metallic shell layer. The underlying reason for this lies beyond classical electromagnetic theory, where plasmon-resonant nanoparticles follow a mesoscale analogue of molecular orbital theory, hybridizing in precisely the same manner as the individual atomic wave functions in simple molecules. This plasmon hybridization picture provides an essential “design rule” for metallic nanostructures that can allow us to effectively predict their optical resonant properties. Such a systematic control of the far-field optical resonances of metallic nanostructures is accomplished simultaneously with control of the field at the surface of the nanostructure. The nanoshell geometry is ideal for tuning and optimizing the near-field response as a stand-alone surface-enhanced Raman spectroscopy (SERS) nanosensor substrate and as a surface-plasmon-resonant nanosensor.Tuning the plasmon resonance of nanoshells into the near-infrared region of the spectrum has enabled a variety of biomedical applications that exploit the strong optical contrast available with nanoshells in a spectral region where blood and tissue are optimally transparent.

We consider a class of higher order (quartet) Bragg resonance involving two incident wave components and a bottom ripple component (so called class III Bragg resonance). In this case, unlike class I/II Bragg resonance involving a single incident wave and one/two bottom ripple components, the frequency of the resonant wave, which can be reflected or transmitted, is a sum or difference of the incident wave frequencies. In addition to transferring energy across the spectrum leading to potentially significant spectral transformation, such resonances may generate long (infragravity) waves of special importance to coastal processes and engineering applications. Of particular interest here is the case where the incident waves are oblique to the bottom undulations (or to each other) which leads to new and unexpected wave configurations. We elucidate the general conditions for such resonances, offering a simple geometric construction for obtaining these. Perturbation analysis results are obtained for these resonances predicting the evolutions of the resonant and incident wave amplitudes. We investigate special cases using numerical simulations (applying a high-order spectral method) and compare the results to perturbation theory: infragravity wave generation by co- and counter-propagating incident waves normal to bottom undulations; longshore long waves generated by (bottom) oblique incident waves; and propagating–standing resonant waves due to (bottom) parallel incident waves. Finally, we consider a case of multiple resonance due to oblique incident waves on bottom ripples which leads to complex wave creation and transformations not easily tractable with perturbation theory. These new wave resonance mechanisms can be of potential importance on continental shelves and in littoral zones, contributing to wave spectral evolution and bottom processes such as sandbar formation.

"Extracting useful machine learning features from acoustic resonance spectra of coupled multi-body structures." Journal of the Acoustical Society of America 151, no. 4 (April 2022): A232. http://dx.doi.org/10.1121/10.0011159.
The usefulness of machine learning algorithms is highly dependent on the formulation of relevant features that sufficiently represent the model. Acoustic resonance spectra consist of a series of peaks, representing resonant modes of the system and contain detailed information about the system structure, material, boundary forces, etc. We present a technique for extracting useful features from dense acoustic resonance spectra of multi-component systems. For simple geometries, the resonance spectrum is relatively sparse and it is feasible to track individual peaks to quantify properties of the system. However, for multi-component systems, the acoustic resonance spectra consist of overlapping peaks, corresponding to resonances in different components. As a result, a high density of peaks exists, and some peak positions are sensitive to changes in the contact between components. Thus, tracking specific resonance modes becomes challenging. Instead, we combine principles from wavelet transformation, nonlinear normalization, and genetic algorithm optimization to extract useful features from complicated acoustic resonance spectra. We demonstrate this technique on simulated acoustic resonance spectra for multi-layer structures. Here, we are measuring the thickness of a specific layer, which is hampered by changes in the acoustic resonance spectrum due to variation in the other layer thicknesses as well as delamination defects.

The monograph is devoted to the study of nonlinear first order systems in the plane where the principal term is the gradient of a positive and positively 2-homogeneous Hamiltonian (or the convex combination of two of such gradients). After some preliminaries about positively 2-homogeneous autonomous systems, some results of existence and multiplicity of T-periodic solutions are presented in case of bounded or sublinear nonlinear perturbations. Our attention is mainly focused on the occurrence of resonance phenomena, and the corresponding results rely essentially on conditions of Landesman-Lazer or Ahmad-Lazer-Paul type. The techniques used are predominantly topological, exploiting the theory of coincidence degree and the use of the Poincaré-Birkhoff fixed point theorem. At the end, other boundary conditions, including the Sturm-Liouville ones, are taken into account, giving the corresponding existence and multiplicity results in a nonresonant situation via the shooting method and topological arguments.

Les instruments a vent a anche simple (clarinette, saxophone) comme plus generalement les instruments de musique a son entretenu sont des systemes physiques dits autooscillant. Afin de determiner leurs solutions en regime permanent, nous avons adapte la methode d'equilibrage harmonique a ces systemes physiques, par la convergence simultanee des harmoniques du signal suppose periodique et de la frequence fondamentale. En mettant au point un systeme micro-intervalle quart de ton sur le saxophone alto, nous avons ete confrontes a des difficultes d'emission sur certaines notes du registre grave de l'instrument. La resolution de ce probleme nous a amene a preciser les roles respectifs du resonateur et du systeme excitateur sur les caracteristiques de l'oscillation. Il est utile de connaitre les frequences de resonance du systeme caracterise par l'impedance d'entree du resonateur en parallele avec l'impedance d'anche, frequences qui correspondent aux frequences de jeu du systeme autooscillant. En etudiant le cas extreme d'oscillations quasi-periodiques (les notes qui roulent), nous avons relie leur inharmonicite avec la facilite d'emission.

L'essentiel de la production de zirconium est utilise par l'industrie nucleaire pour le gainage des combustibles des reacteurs ainsi que pour le stockage des dechets radioactifs. L'objectif de ce travail est l'etude qualitative et quantitative des complexes formes par le zirconium avec les ions hydroxyle et carbonate afin d'evaluer, a long terme, les risques d'eventuelles pollutions dues a la corrosion des conteneurs de confinement. Le systeme zirconium(iv)/hydroxyle est etudie par protometrie en suivant un protocole reduisant les surconcentrations locales de reactif et la precipitation de l'hydroxyde de zirconium. En milieu nitrate de potassium, dans une gamme de ph 1,5 a 3,5, trois especes solubles sont mises en evidence : zr(oh) 3 +, zr 2(oh) 7 + et zr(oh) 4. Leurs constantes apparentes de formation ainsi que le produit de solubilite de l'hydroxyde de zirconium sont determines a quatre forces ioniques. A partir de ces resultats, les constantes thermodynamiques correspondantes sont calculees par application de la theorie des interactions specifiques. La formation des complexes hydroxocarbonates du zirconium(iv) est mise en evidence par protometrie et rmn 1 7o et 1 3c. Le nombre de carbonates fixes par zirconium varie de 0 a 4 ; la dialyse indique que le degre de polycondensation des especes est fonction inverse du nombre de carbonates complexes. Les spectres polarises raman ainsi que les resultats de rmn 1 3c prouvent, pour l'ensemble des complexes, le caractere bidente du mode de complexation des carbonates. L'etude dynamique suivie par rmn 1 3c de l'echange entre carbonates complexes de l'ion tetracarbonatozirconate et carbonates libres en solution permet de determiner les constantes cinetiques et la loi de vitesse correspondante. Un mecanisme associatif est propose, en accord avec les resultats obtenus par spectrometrie de masse avec ionisation electrospray. Ces nouvelles donnees thermodynamiques et cinetiques permettent de modeliser la speciation du zirconium dans les eaux naturelles.

Imager des objets non-périodiques à une échelle nanométrique et à une échelle femto seconde est un vrai challenge à notre époque. Les techniques d’imagerie « sans lentille » sont des moyens puissants pour répondre à ce besoin. En utilisant des sources ultrarapide (~fs) et cohérente (ex. laser à électron libre ou harmoniques d’ordres élevés), ces techniques nous permettent de reconstruire des objets à partir de leur figure de diffraction, remplaçant les optiques conventionnelles du système d’imagerie par un algorithme informatique. Dans ce travail de thèse, je présent des expériences d’imageries en utilisant un rayonnement extrême-UV (15~40 nm) produit par la génération d’harmoniques d’ordre élevé d’un laser infrarouge puissant. Ce manuscrit est constitué d’une introduction, un chapitre de background théorique, trois chapitres de travail de thèse et une conclusion générale avec perspectives. La première partie du travail de thèse porte sur les développements et caractérisations de la ligne de lumière avec l’objectif de générer maximum de photons harmoniques cohérents avec un front d’onde plat. La deuxième partie est consacrée aux expériences et analyses de trois techniques d’imageries « sans lentille » : Imagerie par diffraction cohérente (CDI), Holographie par la transformée de Fourier (FTH) et Holographie avec références étendues (HERALDO). Ces derniers nous permettent de reconstruire des objets avec une résolution spatiale de 78 nm dans le cas de CDI et de 112 nm dans le cas de HERALDO, tous les deux avec une résolution temporaire de 20 fs. La troisième partie est une première application physique de l’imagerie sur la ligne harmonique. Il s’agit des études statiques et dynamiques de nano-domaines magnétique avec une résolution spatiale sub-100 nm à l’échelle femto seconde. Perspective des techniques d’imagerie 3D et développement potentiel de la ligne d’harmoniques sont présentés à la fin Ultrafast imaging of isolated objects with nanometric spatial resolution is a great challenge in our time. The lensless imaging techniques have shown great potential to answer this challenge. In lensless imaging, one can reconstruct sample images from their diffraction patterns with computational algorithms, which replace the conventional lens systems. Using ultrafast and coherent light sources, such as free electron laser and high order harmonics, one can investigate dynamic phenomena at the femtosecond time scale. In this thesis work, I present the lenless imaging experiments using XUV radiation provided by a laser driven high order harmonic beamline. The manuscript is composed of an introduction, a chapter of theoretical background, three chapters of main research work and a general conclusion with perspectives. The first part of this work concerns the development of the harmonic beamline to optimize the illumination condition for lensless imaging. The second part concentrates on the imaging techniques: the Coherent Diffraction Imaging (CDI), the Fourier Transform Holography (FTH) and the Holography using extended references (HERALDO). The reconstructions have achieved 78 nm spatial resolution in case of CDI and 112 nm resolution in case of HERALDO, both in single-shot regime corresponding to a temporal resolution of 20 fs. The third part presents the first physical application on the harmonic beamline using the lensless imaging. Samples with magnetic nano-domains have been studied with sub-100 nm spatial resolution, which paves the way for ultrafast magnetic dynamic studies. At the end, single-shot 3D imaging and further beamline development have been discussed

It is non-invasive and avoids patient exposure to ionizing radiation. MRI has the advantage of establishing diagnoses in a painful knee without the morbidity of surgical intervention. It is now widely available and has moved from a simple diagnostic adjunct into a key planning tool. It offers improved management of theatre resources and it allows for more accurate planning of postoperative rehabilitation.The role of MRI in management of the injured knee is determined by its cost-effectiveness and its ability to augment the diagnostic accuracy of clinical examination. Accuracy of clinical examination by specialist orthopaedic surgeons is comparable to MRI when interpreted by specialist radiologists (Table 8.3.1). Increasingly, MRI has been shown to be cost neutral. Whilst costs are high, diagnostic information reduces the need for unnecessary surgery.

In a polyuric patient, first exclude osmotic diuresis, then differentiate between primary polydipsia, central, and nephrogenic diabetes insipidus, with clinical characteristics, simple blood and urine tests, and hypothalamic magnetic resonance imaging. Mammals are osmoregulators and osmolality is perceived by central and peripheral osmotic receptors and influencing thirst perception and vasopressin secretion. In congenital polyuric states it is useful to distinguish ‘pure’ polyuric states, that is, loss of water only but normal conservation of sodium, potassium, chloride, and calcium, from complex (water + sodium + calcium) polyuric states. For the latter, the triad polyuria/polyhydramnios/prematurity is a tell-tale sign of Bartter syndrome. We recommend sequencing of the nephrogenic diabetes insipidus and Bartter genes in all the affected congenital and hereditary polyuric patients. Acquired central and nephrogenic polyuric states are simpler to evaluate.

Common symptoms of pulmonary disease include cough, sputum, hemoptysis, dyspnea, chest pain, cyanosis, and clubbing. A thorough history and physical examination, including palpation, auscultation, and percussion, are key to accurate diagnosis. The radiologic tests performed in the diagnosis of chest diseases include plain CXR, CT, magnetic resonance imaging, pulmonary angiography, and bronchial angiography. Simple microscopy with a "wet" slide preparation of sputum is helpful in assessing the degree of sputum eosinophilia and detecting the presence of Charcot-Leyden crystals. The major indication for pulmonary function tests (PFTs) is dyspnea. PFT results do not diagnose lung disease, but they are used to assess the mechanical function of the respiratory system and to quantify the loss of lung function. Obstructive, restrictive, and occupational lung diseases are reviewed.

This article considers molecular electronics based on self-assembled monolayers. It begins with a brief overview of the nanofabrication of molecular devices, followed by a discussion of the electronic properties of several basic devices, from simple molecules such as molecular tunnel junctions and molecular semiconducting wires, to more complex ones such as molecular rectifying diodes. It also describes molecular switches and memories, focusing on three approaches called ‘conformational memory’, ‘charge-based memory’ and ‘RTD-based memory’ (RTD is resonant tunnelling diode). It shows that memory can be implemented from resonant tunnelling diodes following cell architecture already used for semiconductor devices. The article concludes with a review of molecular transistors.

Human beings are permanently required to process the world numerically and, consequently, to perform computations to adapt their behaviour and they have developed various calculation strategies, some of them based on specific manipulations of the fingers. In this chapter, we argue that the way we express physically numerical concepts by raising fingers while counting leads to embodied representations of numbers and calculation procedures in the adult brain. To illustrate this, we focus on number and finger interactions in the context of simple arithmetic operations. We show that the fixed order of fingers on the hand provides human beings with unique facilities to increment numerical changes or represent a cardinal value while solving arithmetic problems. In order to specify the influence of finger representation on mental arithmetic both at the cognitive and neural level, we review past and recent findings from behavioural, electrophysiological, and brain imaging studies. We start with anthropological and developmental data showing the role of fingers in the acquisition of arithmetic knowledge, then address the issue of whether number and finger interactions are also observed in adults solving arithmetic problems mentally. We suggest that arithmetic performance depends on the integrity of finger representations in children and adults. Finally, we overview the results of recent functional magnetic resonance imaging (fMRI) studies showing a common brain substrate for finger and number representations during and after the acquisition of arithmetic skills.

Mechanical properties of bonds are discussed, with the aid of a simple phenomenological model in which the variation of energy as a function of distance between the elements is described in terms of polynomials. The properties of various kinds of bonds (ionic bond, metallic bond, covalent bond, van der Waals bond) are explained with the aid of simple models. Carbon is discussed with two examples: bonds between 60 atoms that lead to the formation of a three-dimensional molecule known as Buckminsterfullerene, and the alternative sheet-shaped configuration known as graphene, that has recently become the centre of interest. A general theory for finding the energy levels is introduced, relying on Feynman’s coupled wave equations. There is a brief reference to nuclear forces, followed by a discussion of the hydrogen molecule. The relationship between coupling and the splitting of the energy levels is discussed with an analogy to coupled resonant circuits.

Abstract This chapter will introduce a system that is fundamental to our understanding of more physical phenomena than any other. Although the “simple” harmonic oscillator seems to be only the combination of the most mundane components, the formalism developed to explain the behavior of a mass, spring, and damper is used to describe systems that range in size from atoms to oceans. Our investigation goes beyond the “traditional” treatments found in the elementary physics textbooks. For example, the introduction of damping will open a two-way street: a damping element (i.e., a mechanical resistance, Rm) will dissipate the oscillator’s energy, reducing the amplitudes of successive oscillations, but it will also connect the oscillator to the surrounding environment that will return thermal energy to the oscillator. The excitation of a harmonic oscillator by an externally applied force, displacement, or combination of the two will result in a response that is critically dependent upon the relationship between the frequency of excitation and the natural frequency of the oscillator and will introduce the critical concepts of mechanical impedance, resonance, and quality factor. Finally, the harmonic oscillator model will be extended to coupled oscillators that are represented by combinations of several masses and several springs.

The laser dynamics arising from quasi-resonant interaction between a single mode field and a medium with a homogeneously broadened gain line is described by the equations coupling five variables, namely, the complex field amplitude E, the complex medium polarization P and the real population inversion D. At resonance, E and P are real and the equations reduce to where k, γ1 and γ11 are the relaxation rates of field, polarization and population, respectively, and D0 is the population imposed by the pump.

Split resonance and backward whirl in a simple rotor, were investigated both analytically and experimentally. A two degree-of-freedom rotor model was developed to simulate the steady state, lateral vibration characteristics of a simply supported, single disk rotor. This model included the effects of direct and cross coupled, linear damping and stiffness. The computer model was used to quantify the influence of bearing characteristics on rotordynamic response. In the absence of gyroscopic effects, split resonance is due to separate and distinct natural frequencies in the two orthogonal lateral directions created by non-equal direct stiffnesses. Backward whirl can occur between these two frequencies if the direct damping is sufficiently low. The model was able to predict the observed response of a simply supported rotor, including split resonance and backward whirl. The cause of the asymmetric direct stiffnesses in the experimental apparatus, which created split resonance and backward whirl was investigated. In particular, the influence of geometric imperfections in the plain bearing sleeve, gravitational forces, degree of imbalance and bearing support stiffness asymmetries were isolated using the experimental apparatus. It was determined that the bearing asymmetry was caused by the gravitational influence. However, larger imbalances increased the asymmetry and large damping was able to suppress backward whirl.

Discerning the dynamics of complex systems in a mathematically rigorous and physically consistent manner is as fascinating as intimidating of a challenge, stirring deeply and intrinsically with the most fundamental Physics, while at the same time percolating through the deepest meanders of quotidian life. The socio-natural coevolution in climate dynamics is an example of that, exhibiting a striking articulation between governing principles and free will, in a stochastic-dynamic resonance that goes way beyond a reductionist dichotomy between cosmos and chaos. Subjacent to the conceptual and operational interdisciplinarity of that challenge, lies the simple formal elegance of a lingua franca for communication with Nature. This emerges from the innermost mathematical core of the Physics of Coevolutionary Complex Systems, articulating the wealth of insights and flavours from frontier natural, social and technical sciences in a coherent, integrated manner. Communicating thus with Nature, we equip ourselves with formal tools to better appreciate and discern complexity, by deciphering a synergistic codex underlying its emergence and dynamics. Thereby opening new pathways to see the “invisible” and predict the “unpredictable” – including relative to emergent non-recurrent phenomena such as irreversible transformations and extreme geophysical events in a changing climate. Frontier advances will be shared pertaining a dynamic that translates not only the formal, aesthetical and functional beauty of the Physics of Coevolutionary Complex Systems, but also enables and capacitates the analysis, modelling and decision support in crucial matters for the environment and society. By taking our emerging Physics in an optic of operational empowerment, some of our pioneering advances will be addressed such as the intelligence system Earth System Dynamic Intelligence and the Meteoceanics QITES Constellation, at the interface between frontier non-linear dynamics and emerging quantum technologies, to take the pulse of our planet, including in the detection and early warning of extreme geophysical events from Space.
