description: Nanotechnology refers to the manipulation or design of materials and structures with desired features in the 1nm–1000 nm size range. The blood brain barrier (BBB) is a major obstacle that drugs must overcome in order to reach tumor cells. The role of this barrier is to transport essential nutrients while protecting and regulating the internal environment. Nanoparticles have been shown to transport drugs through this barrier and accumulate in tumor cells. This is significant since nanoparticles are drug carriers allowing chemotherapeutic drugs to accumulate in target areas (Sun et al., 2017). This is possible because they are able to be modified to overexpress specific peptides or membrane markers that are found in these target areas. Once the nanoparticle reaches these anatomical barriers they bind to the correct receptor and move into the area. They can then accumulate and drop their payload which may include a chemotherapeutic drug or contrast agent. This release is sensed by specific pH or temperature changes (Cheng, Morshed, Auffinger, Tobias, & Lesniak, 2014). Nanoparticles can contain different types of elements with unique properties. These properties can be optical, magnetic, or thermal resonating (Savale, 2015). They can be used in both imaging and treating tumors such as glioblastomas. However, there may be potential side effects that are currently not well understood (Wikipedia, 2019b). Nanoparticles are known to have a low toxicity when compared to other drugs (Wikipedia, 2019b). However, high toxicity levels can lead to alarming effects such as affecting other organs and their function (Savale, 2015). Cancer in the brain such as a glioblastoma (GBM) is one of the most active and lethal cancers. Unfortunately, there is no known effective treatment; however, the use of nanoparticles has opened a new door into fighting this disease. This paper will discuss the relationships that nanoparticles have in treating cerebral tumors as well as imaging of cerebral tumors.

description: The study will use an experiment to test whether varying characteristics of the text and images within misinformation content impacts sharing related behavior (such as likes, comments, re-shares, retweets etc. on social media). We intend to test for various mediators and moderators of the relationship between image/text characteristics and sharing outcomes, and control for participants' pre-existing attitudes and their demographics (e.g. age, gender, nationality etc.). Issues examined will relate to those that are more socially divisive and controversial (e.g. related to politics or controversial public figures) versus those that are not (e.g. related to brands, fashion, and trends).

Deep visual learning with spike-timing dependent plasticity
Creators: name: Author, Unknown
Publisher: name: University of Lincoln
Year: 2023
Subjects: I100 - Computer science

description: For most animal species, reliable and fast visual pattern recognition is vital fortheir survival. Ventral stream, a primary pathway within visual cortex, plays an importantrole in object representation and form recognition. It is a hierarchical systemconsisting of various visual areas, in which each visual area extracts different level ofabstractions. It is known that the neurons within ventral stream use spikes to representthese abstractions. To increase the level of realism in a neural simulation, spikingneural network (SNN) is often used as the neural network model. From SNN point ofview, the analog output values generated by traditional artificial neural network (ANN)can be considered as the average spiking firing rates. Unlike traditional ANN, SNNcan not only use spiking rates but also specific spiking timing sequences to representthe structural information of the input visual stimuli, which greatly increases the distinguishability.To simulate the learning procedure of the ventral stream, various research questionsneed to be resolved. In most cases, traditional methods use winner-take-all strategy todistinguish different classes. However, such strategy works not well for overlappedclasses within decision space. Moreover, neurons within ventral stream tends to recognizenew input visual stimuli in a limited time window, which requires a fast learningprocedure. Furthermore, within ventral stream, neurons receive continuous input visualstimuli and can only access local information during the learning procedure. However,most traditional methods use separated visual stimuli as the input and incorporateglobal information within the learning period. Finally, to verify the universality of theproposed SNN framework, it is necessary to investigate its classification performancefor complex real world tasks such as video-based face disguise recognition.To address the above problems, a novel classification method inspired by the softIwinner-take-all strategy has been proposed firstly, in which each associated class willbe assigned with a possibility and the input visual stimulus will be classified as theclass with the highest possibility. Moreover, to achieve a fast learning procedure, anovel feed-forward SNN framework equipped with an unsupervised spike-timing dependentplasticity (STDP) learning rule has been proposed. Furthermore, an eventdrivencontinuous STDP (ECS) learning method has been proposed, in which twonovel continuous input mechanisms have been used to generate a continuous inputvisual stimuli and a new event-driven STDP learning rule based on the local informationhas been applied within the training procedure. Finally, such methodologies havealso been extended to the video-based disguise face recognition (VDFR) task in whichhuman identities are recognized not just on a few images but the sequences of videostream showing facial muscle movements while speaking

description: Quantum oscillation measurements can provide important information about the Fermi surface (FS) properties of strongly correlated metals. Here, we report a Shubnikov-de Haas (SdH) effect study on the pnictide parent compounds EuFe$_{2}$As$_{2}$ (Eu122) and BaFe$_{2}$As$_{2}$ (Ba122) grown by In-flux. Although both members are isovalent compounds with approximately the same density of states at the Fermi level, our results reveal subtle changes in their fermiology. Eu122 displays a complex pattern in the Fourier spectrum, with band splitting, magnetic breakdown orbits, and effective masses sistematically larger when compared to Ba122, indicating that the former is a more correlated metal. Moreover, the observed pockets in Eu122 are more isotropic and 3D-like, suggesting an equal contribution from the Fe $3d$ orbitals to the FS. We speculate that these FS changes may be responsible for the higher spin-density wave ordering temperature in Eu122.

description: We present the results of a survey for CaII 3934,3969 absorption-line systems culled from ~ 95,000 Sloan Digital Sky Survey (SDSS) Data Release 7 and Data Release 9 quasar spectra. With 435 doublets identified in the catalog, this list is the largest CaII catalog compiled to date, spanning redshifts z < 1.34, which corresponds to the most recent ~ 8.9 Gyrs of the history of the Universe. We derive statistics on the CaII rest equivalent width distribution (REW) and incidence (number density per unit redshift). We find that the lambda3934 REW distribution cannot be described by a single exponential function. A double exponential function is required to produce a satisfactory description. The function can be written as a sum of weak and strong components: dn/dW = (N_wk*/W_wk*) exp(-W/W_wk*) + (N_str*/W_str*) exp(-W/W_str*). A maximum likelihood fit to the unbinned data indicates: N_wk*=0.140 +/- 0.029, W_wk*=0.165 +/- 0.020 A, N_str*=0.024 +/- 0.020, and W_str*=0.427 +/- 0.101 A. This suggests that the CaII absorbers are composed of at least two distinct populations. The incidence (product of integrated absorber cross section and their co-moving number density) of the overall CaII absorber population does not show evidence for evolution in the standard cosmology. The normalization of the no-evolution curve, i.e., the value of the CaII incidence extrapolated to redshift z=0, for lambda 3934 >= 0.3 A, is n_0=0.017 +/- 0.001. In comparison to MgII surveys, we found that only 3% of MgII systems in the SDSS have CaII, confirming that it is rare to identify CaII in quasar absorption-line surveys. We also report on some preliminary investigations of the nature of the two populations of CaII absorbers, and show that they can likely be distinguished using their MgII properties.

Agire liberamente implica la capacità di governare la sequenza tra fine e mezzo.

description: A numerical solution is presented for the natural convection from inclined wall plumes which arise from a line thermal source imbedded at the leading edge of an adiabatic plate with arbitrary tilt angle and embedded in a fluid-saturated porous medium.

description: Using a Coulomb gas technique, we compute analytically the probability $\mathcal{P}_β^{(C)}(N_+,N)$ that a large $N\times N$ Cauchy random matrix has $N_+$ positive eigenvalues, where $N_+$ is called the index of the ensemble. We show that this probability scales for large $N$ as $\mathcal{P}_β^{(C)}(N_+,N)\approx \exp\left[-βN^2 ψ_C(N_+/N)\right]$, where $β$ is the Dyson index of the ensemble. The rate function $ψ_C(κ)$ is computed in terms of single integrals that are easily evaluated numerically and amenable to an asymptotic analysis. We find that the rate function, around its minimum at $κ=1/2$, has a quadratic behavior modulated by a logarithmic singularity. As a consequence, the variance of the index scales for large $N$ as $\mathrm{Var}(N_+)\sim σ_C\ln N$, where $σ_C=2/(βπ^2)$ is twice as large as the corresponding prefactor in the Gaussian and Wishart cases. The analytical results are checked by numerical simulations and against an exact finite $N$ formula which, for $β=2$, can be derived using orthogonal polynomials.

description: From the physical point of view entanglement witnesses define a universal tool for analysis and classification of quantum entangled states. From the mathematical point of view they provide highly nontrivial generalization of positive operators and they find elegant correspondence with the theory of positive maps in matrix algebras. We concentrate on theoretical analysis of various important notions like (in)decomposability, atomicity, optimality, extremality and exposedness. Several methods of construction are provided as well. Our discussion is illustrated by many examples enabling the reader to see the intricate structure of these objects. It is shown that the theory of entanglement witnesses finds elegant geometric formulation in terms of convex cones and related geometric structures.

Bias in voting behaviour: endogenous and exogenous factors

Publisher: name: University of Lincoln

Subjects: C880 - Social psychology

description: Despite the vast research on the social bias in decision-making, relatively little isknown about biases in voting behaviour. The main aim of this research was to explorealternative indirect methods to observe biases in decision-making and voting behaviour. Aproximity bias was first observed in the rather unusual setting of the Weakest Link TVgame show, when contestants avoided casting negative votes against their closestneighbours. This proximity bias was most profound for the contestant closest to the voter.Two field experiments were designed to test whether this Neighbour Effect occurred indifferent social contexts, among the first-year undergraduate students. The first study askedfirst-year undergraduate students in a lecture (n=449) to vote for another person seated inthe same row. The same Neighbour Effect occurred when the vote carried a nasty(negative) outcome for the recipient however, when the vote valence changed to a nice(positive) outcome the Neighbour Effect disappeared. In negative voting, the result of thefield experiment confirmed the original observation in the Weakest Link. However, areverse polarity voting pattern was also found in the positive voting. This suggestsparticipants significantly favoured their closest neighbour(s). The second field experimentused Prisoner’s Dilemma with undergraduates in a lecture theatre (n= 229) to test theNeighbour Effect. The undergraduates played the game with another player seated in thesame row and in the same block in a lecture theatre. The results showed a neighbour effectbecause the players were significantly more likely to cooperate with a neighbour that anon-neighbour. To conclude the findings from this study suggested that the NeighbourEffect is a robust bias in strategic decision-making and voting.

description: La filosofia in Grecia sembra acquisire la sua configurazione prendendo le distanze dalla poesia e dalla tragedia, luoghi di raccolta di passioni ed emozioni, dove queste, fin da tempi remoti, avevano trovato la possibilità di venire alla parola. La poesia epica di Omero tratta delle passioni, e l'ira è stata considerata non a torto la prima parola della letteratura europea. L'ira era la linea che separava l'offesa dalla vendetta, ed era capace di reintegrare la dignità offesa dell'eroe. È l'ira che protegge dal rischio di essere asserviti ad altri. Così si comincia a strutturare la soggettività occidentale scissa tra la minaccia della morte e l'asservimento. Tutto ruota intorno alla questione di come si possa essere "liberi" e contemporaneamente vivere insieme ad altri che parimenti sono "liberi". In questo contesto sorgono e trovano spazio i problemi dell'umana convivenza e delle passioni.

description: Two-component mixtures in optical lattices reveal a rich variety of different phases. We employ an exact diagonalization method to obtain the relevant correlation functions in hexagonal optical lattices to characterize those phases. We relate the occupation difference of the two species to the magnetic polarization. `Iso'-magnetic correlations disclose the nature of the system, which can be of easy-axis type, bearing phase segregation, or of easy-plane type, corresponding to super-counter-fluidity. In the latter case, the correlations reveal easy-plane segregation, involving a highly-entangled state. We identify striking correlated supersolid phases appearing within the superfluid limit.

description: Relativistic world-line Hamiltonian for strongly interacting 3q systems in magnetic field is derived from the path integral for the corresponding Green's function. The neutral baryon Hamiltonian in magnetic field obeys the pseudomomentum conservation and allows a factorization of the c.m. and internal motion. The resulting expression for the baryon mass in magnetic field is written explicitly with the account of hyperfine, OPE and OGE (color Coulomb) interaction. The neutron mass is fast decreasing with magnetic field, losing 1/2 of its value at eB~0.25 GeV^2 and is nearly zero at eB~0.5 GeV^2. Possible physical consequences of the calculated mass trajectory of the neutron, M_n(B), are presented and discussed.

description: In this study, through various tests one theoretical model is presented to describe the relationship between promoter strength and its nucleotide sequence. Our analysis shows that, promoter strength is greatly influenced by nucleotide groups with three adjacent nucleotides in its sequence. Meanwhile, nucleotides in different regions of promoter sequence have different effects on promoter strength. Based on experimental data for {\it E. coli} promoters, our calculations indicate, nucleotides in -10 region, -35 region, and the discriminator region of promoter sequence are more important than those in spacing region for determining promoter strength. With model parameter values obtained by fitting to experimental data, four promoter libraries are theoretically built for the corresponding experimental environments under which data for promoter strength in gene expression has been measured previously.

description: We implemented a parallel version of the multicanonical algorithm and applied it to a variety of systems with phase transitions of first and second order. The parallelization relies on independent equilibrium simulations that only communicate when the multicanonical weight function is updated. That way, the Markov chains efficiently sample the temporary distributions allowing for good estimations of consecutive weight functions. The systems investigated range from the well known Ising and Potts spin systems to bead-spring polymers. We estimate the speedup with increasing number of parallel processes. Overall, the parallelization is shown to scale quite well. In the case of multicanonical simulations of the $q$-state Potts model ($q\ge6$) and multimagnetic simulations of the Ising model, the optimal performance is limited due to emerging barriers.

description: When placed onto a vibrating liquid bath, a droplet may adopt a permanent bouncing behavior, depending on both the forcing frequency and the forcing amplitude. The relationship between the droplet deformations and the bouncing mechanism is studied experimentally and theoretically through an asymmetric and dissipative bouncing spring model. Antiresonance effects are evidenced. Experiments and theoretical predictions show that both resonance at specific frequencies and antiresonance at Rayleigh frequencies play crucial roles in the bouncing mechanism. In particular, we show that they can be exploited for droplet size selection.

description: Compte tenu de toutes les exigences imposées aux enseignant-e-s en matière de programme, il est compréhensible qu’ils souhaitent rechercher des techniques prêtes à l'emploi qui peuvent soutenir instantanément le développement du potentiel créatif des élèves (Ingersoll, 2003). En d’autres termes, qu'est-ce qu'un-e enseignant-e devrait faire pour privilégier le développement de la créativité des élèves à l’école obligatoire ? Les enseignant-e-s sont désireux d’en apprendre plus sur la nature la créativité mais ils veulent des techniques concrètes qui les aideraient à la mettre en avant au sein de leur classe. Pour favoriser le développement de la créativité des élèves à l'école obligatoire, il serait pertinent d'inclure l'élève dans la manière d'aborder un enseignement centré sur le développement de sa créativité. Il conviendrait donc de privilégier une centration de l'enseignement sur l'élève pour mieux comprendre et identifier les différents aspects à prendre en compte pour favoriser le développement de sa créativité. En effet, nous pensons qu’en ayant accès à leurs conceptions, nous pourrons avoir un impact favorable sur le développement de leur créativité. Dans cette perspective, nous privilégions une centration sur le point de vue des élèves en adoptant une méthode de recherche issue de la théorisation ancrée (Grounded Theory). Aussi, nous proposons une enquête de terrain afin de faire émerger les conceptions de la créativité de 40 élèves issus de deux classes différentes.

description: Ce mémoire professionnel réalisé en didactique de l’histoire à la HEP-Vaud porte sur la question de la propagande communiste et anticommuniste durant la Guerre froide en Suisse et en France. Il s’inscrit dans une réflexion qui touche l’usage de l’image en classe, dans une démarche comparative entre deux pays. D’un point de vue didactique, ce travail part du constat d’une double lacune. La première est que la fonction de l’image est très souvent réduite à illustrer un propos plutôt que d’être placée au centre d’une séquence d’enseignement. La seconde est que le plan d’étude en secondaire II invite rarement les enseignants à mobiliser une démarche comparative entre des espaces géographiques différents. La séquence proposée dans ce travail vise ainsi à mieux comprendre les représentations communistes et anticommunistes durant la Guerre froide et invite les élèves à développer un regard critique avec les affiches de propagande politique. Le dispositif didactique prévu pour cette séquence se déroule sur dix périodes et s’inscrit dans une démarche multiple : tout d’abord, il invite les élèves à répondre à une problématique sur la base d’images (des affiches politiques). Ensuite, il a aussi pour objectif de développer chez les élèves des compétences dans l’analyse de l’image (avec une approche de dénotation et de connotation). Puis, il propose de les initier à la démarche comparative en analysant un phénomène historique qui s’est produit dans deux pays différents. Enfin, le dispositif didactique proposé permet aux élèves de distinguer les faits historiques de leurs représentations et de comprendre ainsi les différents niveaux de discours. Ainsi, cela questionne non seulement les discours des acteurs de l’époque mais amène à réfléchir à la question de la subjectivité historique dans la lecture du passé.

description: Dans cette étude, nous tentons de répondre aux questions suivantes : • Les élèves comprennent-ils ce qui se passe dans leur portable ? À quel degré ? • Est-ce qu’ils s’intéressent au fonctionnement de cet objet qu’ils utilisent tout le temps ? • Comment les réponses à ces deux questions varient selon les variables suivantes : âge, classe, filière au post-obligatoire, métier (si en apprentissage) ? Un questionnaire est soumis aux élèves, pour tester leur connaissance et leur intérêt en rapport aux technologies du portable. À travers l’analyse des réponses, nous pouvons constater que les connaissances des élèves et leur intérêt vis-à-vis du fonctionnement interne de leur portable ne sont pas très élevées. Sur le fond d’un niveau généralement bas, et d’une grande variabilité individuelle, on a remarqué pourtant que les élèves de maturité professionnelle ont des performances meilleures et montrent un plus grand intérêt si on les compare aux élèves en ECG/gymnase. Nous mettons aussi en évidence qu’il y a une correlation entre l’intérêt montré par les élèves et leur connaissances. Si on souhaite que les élèves soient plus conscients des aspects technologiques, et sachent donc adopter des bons comportements et faire des choix judicieux, il est primordial de stimuler leur intérêt sur le sujet, car celui-ci aura un effet sur le questionnement individuel de l’élève, et donc sur l’acquisition de nouvelles connaissances.

Rather it often suffices to find occurrences of a person indicated by the user with an exemplary image sequence. We present two systems in which the search for a specific person can be initiated by a sample image sequence and then be further refined by interactive feedback by the operator. In the first system, episodes of TV series have been processed offline and can be searched for occurrences of the different characters. The second system tracks people online in multiple cameras and makes the sequences immediately searchable from a central station.

description: We study the impact of binary interaction processes on the evolution of low- and intermediate-mass stars using long-term monitoring of their radial velocity. Here we report on our results on the central stars of two planetary nebulae (PNe): the well-studied spectrophotometric standard BD+33.2642 (central star of PNG 052.7+50.7) and HD112313 (central star of PN LoTr5), the optical light of which is dominated by a rapidly rotating G star. The high-resolution spectra were cross-correlated with carefully selected masks of spectral lines. The individual masks were optimised for the spectral signatures of the dominant contributor of the optical light. We report on the first detection of orbital motion in these two objects. For BD+33.2642 we sampled 1.5 cycles of the 1105 +/- 24 day orbital period. For HD 112313 a full period is not yet covered, despite our 1807 days of monitoring. The radial-velocity amplitude shows that it is unlikely that the orbital plane is co-planar with the one defined by the nebular waist of the bipolar nebula. To our knowledge these are the first detections of orbits in PNe that are in a range from several weeks to a few years. The orbital properties and chemical composition of BD+33.2642 are similar to what is found in post-AGB binaries with circumbinary discs. The latter are probably progenitors of these PNe. For LoTr5 the Ba-rich central star and the long orbital period are similar to the Ba star giants, which hence serve as natural progeny. In contrast to the central star in LoTr5, normal Ba stars are slow rotators. The orbits of these systems have a low probability of occurrence according to recent population synthesis calculations.

description: Au cours de l’apprentissage de mon métier, avec ses doutes et ses incertitudes, l’imprévisibilité avait toujours représenté une crainte, voire une hantise. J’avais peur de la déstabilisation engendrée par l’imprévisible, peur de perdre la maîtrise du cours des choses, peur d’en devenir ridicule. Pédagogiquement, accepter l’imprévisible, c’est accepter de lâcher prise et occasionner des savoir de circonstance. Ces savoirs de circonstance stimulent la singularité et la créativité de l’action du maitre. Mais plus loin, l’enseignante ou l’enseignant peut lui-même être à la source d’une imprévisibilité. La faire advenir subitement, c’est susciter de la perplexité et de l’étonnement qui sont les moteurs les plus puissants de l’apprentissage. C’est aussi éviter l’écueil de l’apathie et de l’ennui. C’est enfin engendrer des espaces de potentialité pour stimuler la participation des élèves. Cette imprévisibilité doit toutefois être balisée dans son advenue et sa tenue : toutes les situations ne s’y prêtent pas, le chaos peut soudain l’emporter et détruire un climat d’apprentissage. C’est alors, pour finir, à un savoir-faire de l’imprévisible auquel je fais appel et pour lequel j’ai tracé quelques repères dans ce mémoire.

Highly Accreting Quasars: Sample Definition and Possible Cosmological Implications

description: We propose a method to identify quasars radiating closest to the Eddington limit, defining primary and secondary selection criteria in the optical, UV and X-ray spectral range based on the 4D eigenvector 1 formalism. We then show that it is possible to derive a redshift-independent estimate of luminosity for extreme Eddington ratio sources. Using preliminary samples of these sources in three redshift intervals (as well as two mock samples), we test a range of cosmological models. Results are consistent with concordance cosmology but the data are insufficient for deriving strong constraints. Mock samples indicate that application of the method proposed in this paper using dedicated observations would allow to set stringent limits on Omega_M and significant constraints on Omega_Lambda.

Understanding the design of energy interventions to reduce end-user demand in organisational and domestic environments

description: Energy demand is on the rise globally due to unchecked factors such as population growth, lifestyle choices, and the industrialization of developing countries. Governmentsare investing in technologies for efficient and renewable energy in an attempt to secure energy for the future over current dependencies on fossil fuels, but the development costs are high, and the rate of developed technologies is projected to fall far short of meeting global requirements. Overshadowing this growing appetite for energy is the global issue of climate change, igniting the scientific and humanitarian debate over the use of fossil fuels and a need for renewable energy, presenting a societal problem of generating clean, sustainable and secure energy for future generations. As part of understanding how society can make positive changes to daily practices around energy use, many governments have turned to behaviour change, or ‘nudge’ units, that research work on changing energy consumption behaviours. The importance of this is underlined by a focus on reducing end-user energy demand (EUED) by providing contextual energy feedback, interwoven with behaviour change strategies, in both residential and organizational sectors. EUED in large organisations and small-medium enterprises (SMEs) accounts for a significant proportion of a nation’s energy requirements. In Europe, the services sector saw a 34% growth in EUED in the period 1990-2012, with computers and other appliances in the office substantially contributing to this. In the UK, for example, 13% of total energy consumed in 2011-2012 was within the services sector, which accounts for services and business, while the residential sector consumed 30% of total consumption. Given a lack of academic HCI research in the organisational energy intervention space when comparted to domestic, the principle research undertaken in this thesis was to understand employee energy consumption practices and attitudes in the workplace, through a combination of qualitative enquiry and analysis. Additionally, alternative forms of feedback such as aversive stimuli are often ignored in the HCI literature, with favour focused on positive feedback alone as a means for behaviour change. The work in this thesis presents findings on the design implications and considerations that inform the design of in-the-field organisational energy interventions that integrate feedback and antecedent behaviour contingencies. Additionally, research is undertaken in understanding the design of aversive feedback as part of domestic energy interventions. A significant contribution is made to the HCI sustainability literature on understanding the workplace energy intervention design space, and a contribution made on how aversive feedback can in fact be a useful and engaging method for the domestic environment.

description: A 10 MeV/c $μ^+$ beam was stopped in helium gas of a few mbar in a magnetic field of 5 T. The muon 'swarm' has been efficiently compressed from a length of 16 cm down to a few mm along the magnetic field axis (longitudinal compression) using electrostatic fields. The simulation reproduces the low energy interactions of slow muons in helium gas. Phase space compression occurs on the order of microseconds, compatible with the muon lifetime of 2 $μ$s. This paves the way for preparation of a high quality muon beam.

description: This article discusses the historical research found on the Ichimatsu Ningyo boy doll by Takizawa Koryusai II. This doll is housed by the Barry Arts Museum and is an example of the Japanese Ichimatsu Ningyo art style. The purpose of this project was to discover why and how the doll was created due to the lack of provenance. This investigation will first address the make and style of the doll as well as the symbolism that lies well within its image. Second, it will address the historical significance and future of the Japanese Ningyo doll. By comparing how the doll was created and the symbols within it, this paper seeks to present a more proper understanding of the doll's intended purpose.

description: We demonstrate a two-dimensional time-domain spectroscopy method to extract amplitude and phase modifications of excited atomic states caused by the interaction with ultrashort laser pulses. The technique is based on Fourier analysis of the absorption spectrum of perturbed polarization decay. An analytical description of the method reveals how amplitude and phase information can be directly obtained from measurements. We apply the method experimentally to the helium atom, which is excited by attosecond-pulsed extreme ultraviolet light, to characterize laser-induced couplings of doubly-excited states.
