description: By using a shooting technique, we prove that the quasilinear boundary value problem $$ \textrm{div} \, \left( \frac{\nabla u}{\sqrt{1-| \nabla u |^2}}\right) + λq(| x |) | u |^{p-1} u = 0, \qquad u|_{\partial \mathcal{B}} = 0,$$ where $\mathcal{B} \subset \mathbb{R}^N$ is a ball and $p > 1$, has more and more pairs of nodal solutions on growing of the parameter $λ> 0$. The radial Neumann problem and the periodic problem for the corresponding one-dimensional equation are considered, as well.
Learning to trust, trusting to treat: epistemic trust and significant learning moments for psychotherapy trainees in their own therapy

description: A cornerstone for the personal and professional development of counsellors and psychotherapists is frequently identified in the experiences of their own therapy. But, how does one come to trust another as a reliable source of knowledge about themselves as a person, and as a professional who provides the same support for others? And, what arising within this helping relationship becomes regarded as significant? This study seeks to explore the role of the trainee's attachment pattern to their own therapist as shaping their preparedness to trust this individual as a reliable source of social knowledge. The study used a mixed methodology to firstly quantitatively identify trainee attachment patterns with their treatingtherapist. Semi-structured interviews were used to explore trainee experiences of trust and doubt in themselves and theirtherapist, and significant or teachable moments. A qualitative framework was used to construct plausible models thatreflect different epistemic stances taken with the treating therapist. Following triangulation of a self report measure and a clinician rated scale of the trainees’ attachment to their therapist,a two-group comparison of interviews was made which reflected a contrast between four securely attached, and onetrainee identified as having a hyperactivating attachment orientation to their therapist. The emergence of distinctepistemic stances taken by secure and hyperactivating trainees suggest that the prevailing attachment orientation of thetherapeutic dyad did shape the trainees’ approaches to learning social knowledge and the kinds of moments experiencedas significant. This study represents a first exploration of the linkages between a trainee therapist’s pattern of social learning(epistemic stance) with their own therapist and the subsequent moments they regard as significant. Differences inepistemic stance do indeed shape the trainee’s approach to trusting in and collaborating with another mind, leading todiffering trajectories not just in their own therapies but across the spectrum of social relationships. An awareness ofdiffering epistemic stances across trainees may well sharpen training and development avenues for those individualsidentified as having insecure attachment patterns, as well as potentially shape the ways in which psychotherapy deliveryis offered to these individuals.

description: The rapid growth of e-commerce has placed considerable pressure on customs representatives, prompting advanced methods. In tackling this, Artificial intelligence (AI) systems have emerged as a promising approach to minimize the risks faced. Given that the Harmonized System (HS) code is a crucial element for an accurate customs declaration, we propose a novel multimodal HS code prediction approach using deep learning models exploiting both image and text features obtained through the customs declaration combined with e-commerce platform information. We evaluated two early fusion methods and introduced our MultConcat fusion method. To the best of our knowledge, few studies analyze the featurelevel combination of text and image in the state-of-the-art for HS code prediction, which heightens interest in our paper and its findings. The experimental results prove the effectiveness of our approach and fusion method with a top-3 and top-5 accuracy of 93.5% and 98.2% respectively

description: The center-of-mass motion of a single optically levitated nanoparticle resembles three uncoupled harmonic oscillators. We show how a suitable modulation of the optical trapping potential can give rise to a coupling between two of these oscillators, such that their dynamics are governed by a classical equation of motion that resembles the Schrödinger equation for a two-level system. Based on experimental data, we illustrate the dynamics of this parametrically coupled system both in the frequency and in the time domain. We discuss the limitations and differences of the mechanical analogue in comparison to a true quantum mechanical system.

description: The kinetics of the dehydration of four sizes of spherical inorganic materials was studied experimentally with warm air using a fixed-bed dryer at laboratory scale. Following the evaluation of the effect of bed thickness, air mass rate, and air temperature on drying kinetics, a kinetic model consisting of two equations was proposed. The main novelty of this study resides in the possibility of utilizing a new model for simultaneous heat and mass transfer in an efficient manner for practical applications and appropriate system optimization, especially during the falling rate period.

description: To explore biocompatibility and degradability of alginate-poly-l-arginine (APLA) microcapsules prepared by high-voltage electrostatic process, this study investigated cytotoxicity, blood compatibility, acute toxicity, and in vivo biocompatibility and degradability of APLA microcapsules. The results showed that the uniform APLA microcapsules almost had no cytotoxicity within 1.0 mg/mL, and their degradation products promoted cell proliferation. APLA microcapsules had excellent hemocompatibility even at 200 mg/mL, and their extract products did not create acute toxicity even at 5,000 mg/kg. The inflammatory responses induced by APLA microcapsules were moderate and decreased with time, and APLA microcapsules could be degraded and phagocytized by tissue cells.

description: Water ice-rich patches have been detected on the surface of comet 67P/Churyumov-Gerasimenko by the VIRTIS hyperspectral imager on-board the Rosetta spacecraft, since the orbital insertion in late August 2014. Among those, three icy patches have been selected, and VIRTIS data are used to analyse their properties and their temporal evolution while the comet was moving towards the Sun. We performed an extensive analysis of the spectral parameters, and we applied the Hapke radiative transfer model to retrieve the abundance and grain size of water ice, as well as the mixing modalities of water ice and dark terrains on the three selected water ice rich areas. Study of the spatial distribution of the spectral parameters within the ice-rich patches has revealed that water ice follows different patterns associated to a bimodal distribution of the grains: ~50 μm sized and ~2000 μm sized. In all three cases, after the first detections at about 3.5 AU heliocentric distance, the spatial extension and intensity of the water ice spectral features increased, it reached a maximum after 60-100 days at about 3.0 AU, and was followed by an approximately equally timed decrease and disappearanceat about ~2.2 AU, before perihelion. The behaviour of the analysed patches can be assimilated to a seasonal cycle. In addition we found evidence of short-term variability associated to a diurnal water cycle. The similar lifecycle of the three icy regions indicates that water ice is uniformly distributed in the subsurface layers, and no large water ice reservoirs are present.

description: One of the main problems that emerges in the classic approach to semantics is the difficulty in acquisition and maintenance of ontologies and semantic annotations. On the other hand, the Internet explosion and the massive diffusion of mobile smart devices lead to the creation of a worldwide system, which information is daily checked and fueled by the contribution of millions of users who interacts in a collaborative way. Search engines, continually exploring the Web, are a natural source of information on which to base a modern approach to semantic annotation. A promising idea is that it is possible to generalize the semantic similarity, under the assumption that semantically similar terms behave similarly, and define collaborative proximity measures based on the indexing information returned by search engines. The PMING Distance is a proximity measure used in data mining and information retrieval, which collaborative information express the degree of relationship between two terms, using only the number of documents returned as result for a query on a search engine. In this work, the PMINIG Distance is updated, providing a novel formal algebraic definition, which corrects previous works. The novel point of view underlines the features of the PMING to be a locally normalized linear combination of the Pointwise Mutual Information and Normalized Google Distance. The analyzed measure dynamically reflects the collaborative change made on the web resources.

Can Cyrus speak?: Cyrus the Great and his reception from antiquity to the modern Iranian national-state
Creators: name: Parnian, Natasha
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: The Achaemenid Persian King Cyrus the Great has been remembered as a model ruler in comparison with later despotic Achaemenid kings and as the liberator of Jewish people. More recently, he has been celebrated as a human rights icon, supposedly initiating the first charter of human rights. This idolised view has been appropriated by nationalist agendas of the Iranian state, drawing on a selective reading of ancient classical, Biblical and Near Eastern texts stressing his exceptional leadership. The ongoing attraction to Cyrus is reflective of the appropriation of European colonial scholarship of the nineteenth and twentieth centuries by Iranian nationalists. Utilising a post- structuralist lens, this thesis examines the ancient texts of Herodotus, Xenophon, the books of Ezra and Isaiah and the influential Cyrus Cylinder, investigating the circumstances molding Cyrus' reputation from antiquity to the post-colonial era. This thesis reflects on the complicated representations of Cyrus as part of a broader problem connected to the reconstruction of the Achaemenid Persian; Cyrus' benevolence is routinely polarised against the popular perception of Persian decadence dominating popular perceptions today. By tracing Cyrus' reconstruction from antiquity to the modern Iranian nation-state, this thesis highlights how Iran's pre-Islamic past remains the stage on which ideas about the nation are debated and critiques the outdated discourses inherited and appropriated from Iran's encounter with Europe --summary.

description: Over the past half a century, machine-based text summarization has been addressed from many different perspectives in a variety of application domains. Deep neural networks recently show promising results for text summarization and this thesis explores this application domain. In this research study, a deep auto-encoder is used to rank sentences based on the most salient information. More precisely, a deep neural network has been used for extractive query-oriented single-document summarization. Also, the use of an Ensemble Noisy Auto-Encoder (ENAE) for this task has been evaluated. ENAE is a stochastic version of an auto-encoder that adds noise to the input text and selects the top sentences from an ensemble of runs. Our experiments show that although a deep auto-encoder can be an effective summarizer, deep auto-encoders trained with stochastic noise in the input and run multiple times with different noise in the input can make improvements. The architecture of ENAE changes the application of the auto-encoder from a deterministic feed-forward network to a stochastic model. To cover a wide range of topics and structures, we perform experiments on two different publicly available email corpora that are specifically designed for text summarization.

description: Going beyond the bistability paradigm of the charge polarizations in ferroelectrics is highly desired for ferroelectric (FE) memory devices toward ultra-high-density information storage. Here, we propose to build multistates by combining the intrinsic and sliding-induced polarizations. The physics is that there is at least one order of magnitude difference in the energy barriers between these two types of polarization, which leads to a significant difference in the electric fields for reversing the polarization. This difference, along with the symmetry breaking, allows for a unique flipping mechanism involving layer-by-layer sliding followed by layer-by-layer flipping during the transformation of the multistates. As a result, six and ten switchable states can be achieved for the 1T" bilayers and trilayers, respectively. We further illustrate the concept in H-stacking bilayers and trilayers of 1T" transition-metal dichalcogenides by first-principles calculations. Our study provides a new route to design novel polarization states for developing next-generation memory devices.

description: GLI family zinc finger proteins are transcriptional effectors of the sonic hedgehog signaling pathway. GLI regulates gene expression and repression at various phases of embryonic morphogenesis. In humans, 4 GLI genes are known, and GLI2 (2q14.2) and GLI3 (7p14.1) mutations cause different syndromes. Here, we present 2 distinctive cases with a chromosomal microdeletion in one of these genes. Patient 1 is a 14-year-old girl with Culler-Jones syndrome. She manifested short stature, cleft palate, and mild intellectual/social disability caused by a 6.6-Mb deletion of 2q14.1q14.3. Patient 2 is a 2-year-old girl with Greig cephalopolysyndactyly contiguous gene deletion syndrome. She manifested macrocephaly, preaxial polysyndactyly, psychomotor developmental delay, cerebral cavernous malformations, and glucose intolerance due to a 6.2-Mb deletion of 7p14.1p12.3 which included GLI3, GCK, and CCM2. Each patient manifests a different phenotype which is associated with different functions of each GLI gene and different effects of the chromosomal contiguous gene deletion. We summarize the phenotypic extent of GLI2/3 syndromes in the literature and determine that these 2 syndromes manifest opposite features to a certain extent, such as midface hypoplasia or macrocephaly, and anterior or posterior side of polydactyly. We propose a GLIA/R balance model that may explain these findings.

description: We have used soft x-ray photoemission electron microscopy to image the magnetization of single domain La$_{0.7}$Sr$_{0.3}$MnO$_{3}$ nano-islands arranged in geometrically frustrated configurations such as square ice and kagome ice geometries. Upon thermal randomization, ensembles of nano-islands with strong inter-island magnetic coupling relax towards low-energy configurations. Statistical analysis shows that the likelihood of ensembles falling into low-energy configurations depends strongly on the annealing temperature. Annealing to just below the Curie temperature of the ferromagnetic film (T$_{C}$ = 338 K) allows for a much greater probability of achieving low energy configurations as compared to annealing above the Curie temperature. At this thermally active temperature of 325 K, the ensemble of ferromagnetic nano-islands explore their energy landscape over time and eventually transition to lower energy states as compared to the frozen-in configurations obtained upon cooling from above the Curie temperature. Thus, this materials system allows for a facile method to systematically study thermal evolution of artificial spin ice arrays of nano-islands at temperatures modestly above room temperature.

description: We describe a newly developed polytetrafluoroethylene/copper capacitor driven by a cryogenic piezoelectric slip-stick stage and demonstrate with the chosen layout cryogenic capacitance tuning of ≈60 pF at ≈10 pF background capacitance. Connected to a highly sensitive superconducting toroidal LC circuit, we demonstrate tuning of the resonant frequency between 345 and 685 kHz, at quality factors Q > 100 000. Connected to a cryogenic ultra low noise amplifier, a frequency tuning range between 520 and 710 kHz is reached, while quality factors Q > 86 000 are achieved. This new device can be used as a versatile image current detector in high-precision Penning-trap experiments or as an LC-circuit-based haloscope detector to search for the conversion of axion-like dark matter to radio-frequency photons. This new development increases the sensitive detection bandwidth of our axion haloscope by a factor of ≈1000.

description: High resolution movies in 193 A from the Atmospheric Imaging Assembly (AIA) on the Solar Dynamic Observatory SDO show apparent rotation in the leg of a prominence observed during a coordinated campaign. Such structures are commonly referred to as tornadoes. Time-distance intensity diagrams of the AIA data show the existence of oscillations suggesting that the structure is rotating. The aim of this paper is to understand if the cool plasma at chromospheric temperatures inside the tornado is rotating around its central axis. The tornado was also observed in Halpha with a cadence of 30 seconds by the MSDP spectrograph, operating at the Solar Tower in Meudon. The MSDP provides sequences of simultaneous spectra in a 2D field of view from which a cube of Doppler velocity maps is retrieved. The Halpha Doppler maps show a pattern with alternatively blueshifted and redshifted areas of 5 to 10 arcsec wide. Over time the blueshifted areas become redshifted and vice versa, with a quasi-periodicity of 40 to 60 minutes. Weaker amplitude oscillations with periods of 4 to 6 minutes are superimposed onto these large period oscillations. The Doppler pattern observed in Halpha cannot be interpreted as rotation of the cool plasma inside the tornado. The H$α$ velocity observations give strong constraints on the possible interpretations of the AIA tornado

description: Here, we report on terahertz (THz) radiation generation in air driven by the fundamental and second harmonic of Yb:KGW laser pulses with durations of a few hundred femtoseconds. It was found that the spectrum of generated THz pulses surprisingly spans up to 50 THz, which is comparable to that usually obtained using much shorter Ti:sapphire laser pulses. The broad bandwidth is attributed to a strong spatiotemporal reshaping of the pump pulses in a filament. The achieved energy conversion efficiency is comparable to the one usually obtained from much shorter pump pulses and could be further improved by an optimized experimental setup. The obtained results indicate that compact Yb-based sources provide an attractive alternative to much larger and expensive laser systems.
Effects of heart rate on arterial stiffness

Subjects: Other education not elsewhere classified

description: Both elevated heart rate (HR) and increased arterial wall stiffness are independent predictors for cardiovascular disease and mortality. Whilst it is well established that arteries stiffen with age and increased blood pressure (BP), research findings to date have failed to converge on the relationship between HR and arterial stiffness. This thesis explores the HR-arterial stiffness relationship through the study of pulse wave velocity (PWV) changes, a surrogate measure of arterial stiffness, with changes in HR induced by artificial cardiac pacing in both rodents and humans. In both the rodent study and human study, HR was shown to exert an independent effect on PWV, with PWV increasing as HR increased, and the intrinsic HR dependency of PWV was quantified in the human study as 0.17 m/s per 10 bpm increase in HR. As external cardiac pacing is often used as a means to induce HR changes, as it was in the studies in this thesis,the effect of different pacing modalities on indices of pulse wave analysis and arterial stiffness was also explored. Practical applications of the associations between HR, BP and PWV were also demonstrated through the estimation of systolic times that utilised pulse wave analysis and PWV. To investigate a possible mechanism by which HR exerts an influence on arterial stiffness,a computerised transmission line model of the human arterial tree was utilised to simulate effects of HR on PWV at different scenarios where arterial wall elasticity was modelled with varying frequency dependence. Model simulations showed that frequency dependency of arterial wall elasticity, beyond a critical point, could partly explain the observed increases in PWV with increasing HR. The findings in this thesis not only lend further evidence to an independent HR effect on arterial stiffness, but also provide an insight into the mechanisms behind this relationship. Quantification of the intrinsic HR dependency on PWV will allow for practical application of this established relationship in future cardiovascular studies.

description: The analysis of dynamic organelles remains a formidable challenge, though key to understanding biological processes. We introduce Nellie, an automated and unbiased user-friendly pipeline for segmentation, tracking, and feature extraction of diverse intracellular structures. Nellie adapts to image metadata, eliminating user input. Nellie's preprocessing pipeline enhances structural contrast on multiple intracellular scales allowing for robust hierarchical segmentation of sub-organellar regions. Internal motion capture markers are generated and tracked via a radius-adaptive pattern matching scheme, and used as guides for sub-voxel flow interpolation. Nellie extracts a plethora of features at multiple hierarchical levels for deep and customizable analysis. Nellie features a point-and-click Napari-based GUI that allows for code-free operation and visualization, while its modular open-source codebase invites extension by experienced users. We demonstrate Nellie's wide variety of use cases with three examples: unmixing multiple organelles from a single channel using feature-based classification, training an unsupervised graph autoencoder on mitochondrial multi-mesh graphs to quantify latent space embedding changes following ionomycin treatment, and performing in-depth characterization and comparison of endoplasmic reticulum networks across different cell types and temporal frames.

A Model of Mesons

description: Detailed models of mesons have been derived in terms of real structured particles, in order to replace the formless quark/anti-quark singularities of standard QCD theory. Pion design is related to the muonic mass, and a Yukawa potential is calculated for the hadronic field. A charged pion is produced by adding a heavy-electron or positron in a tight orbit around the neutral core. Other mesons are found to be ordered assemblies of pionic-size masses, travelling in bound epicyclical orbits, with real intrinsic spin and angular momentum. These orbit dimensions are related to the mean lifetimes of the mesons through action integrals. Decay products resemble parts of their parent mesons, as expected for a relaxation process with traceability of particles.

description: Background Alveolar hypoxia is protective in the context of cardiovascular and ischemic heart disease; however, the underlying mechanisms are incompletely understood. The present study sought to test the hypothesis that hypoxia is cardioprotective in left ventricular pressure overload (LVPO)–induced heart failure. We furthermore aimed to test that overlapping mechanisms promote cardiac recovery in heart failure patients following left ventricular assist device‐mediated mechanical unloading and circulatory support. Methods and Results We established a novel murine model of combined chronic alveolar hypoxia and LVPO following transverse aortic constriction (HxTAC). The HxTAC model is resistant to cardiac hypertrophy and the development of heart failure. The cardioprotective mechanisms identified in our HxTAC model include increased activation of HIF (hypoxia‐inducible factor)‐1α–mediated angiogenesis, attenuated induction of genes associated with pathological remodeling, and preserved metabolic gene expression as identified by RNA sequencing. Furthermore, LVPO decreased Tbx5 and increased Hsd11b1 mRNA expression under normoxic conditions, which was attenuated under hypoxic conditions and may induce additional hypoxia‐mediated cardioprotective effects. Analysis of samples from patients with advanced heart failure that demonstrated left ventricular assist device–mediated myocardial recovery revealed a similar expression pattern for TBX5 and HSD11B1 as observed in HxTAC hearts. Conclusions Hypoxia attenuates LVPO‐induced heart failure. Cardioprotective pathways identified in the HxTAC model might also contribute to cardiac recovery following left ventricular assist device support. These data highlight the potential of our novel HxTAC model to identify hypoxia‐mediated cardioprotective mechanisms and therapeutic targets that attenuate LVPO‐induced heart failure and mediate cardiac recovery following mechanical circulatory support.

description: Inflammasomes are critical sentinels of the innate immune system that respond to threats to the host through recognition of distinct molecules, known as pathogen- or damage-associated molecular patterns (PAMPs/DAMPs), or disruptions of cellular homeostasis, referred to as homeostasis-altering molecular processes (HAMPs) or effector-triggered immunity (ETI). Several distinct proteins nucleate inflammasomes, including NLRP1, CARD8, NLRP3, NLRP6, NLRC4/NAIP, AIM2, pyrin, and caspases-4/-5/-11. This diverse array of sensors strengthens the inflammasome response through redundancy and plasticity. Here, we present an overview of these pathways, outlining the mechanisms of inflammasome formation, subcellular regulation, and pyroptosis, and discuss the wide-reaching effects of inflammasomes in human disease.

description: This study investigated the relationship between feet kinematics upon slipping while walking and the outcome of the slip. Seventy-one slips (induced by walking over an unexpectedly slippery surface) were analysed, which included 37 recoveries, 16 feet-split falls, 11 feet-forward falls and seven lateral falls. Feet kinematics differed between recoveries and three types of slip-induced falls, and a discriminant model including six measures of feet kinematics correctly predicted 87% of slip outcomes. Two potentially modifiable characteristics of the feet kinematics upon slipping that can improve the likelihood of successfully averting a fall were identified: (1) quickly arresting the motion of the slipping foot and (2) a recovery step that places the trailing toe approximately 0–10% body height anterior to the sacrum. These results may inform the development of task-specific balance training interventions that promote favourable recovery responses to slipping. Practitioner Summary: This study investigated the relationship between feet movements upon slipping and outcomes of the slip. Potentially modifiable characteristics that can reduce the likelihood of falling were: (1) quickly arresting slipping foot motion and (2) a recovery step that places the trailing toe approximately 0–10% body height anterior to the sacrum.
The relation between the mass-to-light ratio and the relaxation state of globular clusters

description: The internal dynamics of globular clusters (GCs) is strongly affected by two-body interactions that bring the systems to a state of partial energy equipartition. Using a set of Monte Carlo clusters simulations, we investigate the role of the onset of energy equipartition in shaping the mass-to-light ratio (M/L) in GCs. Our simulations show that the M/L profiles cannot be considered constant and their specific shape strongly depends on the dynamical age of the clusters. Dynamically younger clusters display a central peak up to M/L $\simeq25$ $M_\odot/L_\odot$ caused by the retention of dark remnants; this peak flattens out for dynamically older clusters. Moreover, we find that also the global values of M/L correlate with the dynamical state of a cluster quantified as either the number of relaxation times a system has experienced $n_{rel}$ or the equipartition parameter $m_{eq}$: clusters closer to full equipartition (higher $n_{rel}$ or lower $m_{eq}$) display a lower M/L. We show that the decrease of M/L is primarily driven by the dynamical ejection of dark remnants, rather than by the escape of low-mass stars. The predictions of our models are in good agreement with observations of GCs in the Milky Way and M31, indicating that differences in relaxation state alone can explain variations of M/L up to a factor of $\simeq3$. Our characterization of the M/L as a function of relaxation state is of primary relevance for the application and interpretation of dynamical models.

description: We present a scanning probe microscopy technique for spatially resolving transport in cold atomic gases, in close analogy with scanning gate microscopy in semiconductor physics. The conductance of a quantum point contact connected to two atomic reservoirs is measured in the presence of a tightly focused laser beam acting as a local perturbation that can be precisely positioned in space. By scanning its position and recording the subsequent variations of conductance, we retrieve a high-resolution map of transport through a quantum point contact. We demonstrate a spatial resolution comparable to the extent of the transverse wave function of the atoms inside the channel, and a position sensitivity below 10nm. Our measurements agree well with an analytical model and ab-initio numerical simulations, allowing us to identify a regime in transport where tunneling dominates over thermal effects. Our technique opens new perspectives for the high-resolution observation and manipulation of cold atomic gases.

description: In Australia, supermarkets dominate our food landscape, with over eighty-four percent of weekly food purchases occurring at the supermarket. The majority of this shopping occurs at either Coles or Woolworths. Given Coles and Woolworths’ dominance in food retailing, the messages they promote about food form important narratives that establish, reflect and reproduce broader cultural and social beliefs about taste.This thesis uses a combination of topic modelling, a type of machine learning, together with close reading to analyse the supermarket narratives found in the Coles and Woolworths magazines, Coles Magazine and Woolworths’ Fresh, published between 2009 and 2018. My analysis of these narratives demonstrates how supermarkets are positioning themselves as food and lifestyle authorities ready to instruct their customers on how to be good moral citizens through their consumption choices. Although the supermarket duopoly was subjected to intense external scrutiny and criticism from multiple sources during this period, my research finds this had little impact on their magazine narratives. Finally, my research highlights the benefits and analytical richness to be gained from combining topic modelling and close reading when performing content analysis on a large corpus of text
