description: We compute exactly the statistics of the number of records in a discrete-time random walk model on a line where the walker stays at a given position with a nonzero probability $0\leq p \leq 1$, while with the complementary probability $1-p$, it jumps to a new position with a jump length drawn from a continuous and symmetric distribution $f_0(η)$. We have shown that, for arbitrary $p$, the statistics of records up to step $N$ is completely universal, i.e., independent of $f_0(η)$ for any $N$. We also compute the connected two-time correlation function $C_p(m_1, m_2)$ of the record-breaking events at times $m_1$ and $m_2$ and show it is also universal for all $p$. Moreover, we demonstrate that $C_p(m_1, m_2)< C_0(m_1, m_2)$ for all $p>0$, indicating that a nonzero $p$ induces additional anti-correlations between record events. We further show that these anti-correlations lead to a drastic reduction in the fluctuations of the record numbers with increasing $p$. This is manifest in the Fano factor, i.e. the ratio of the variance and the mean of the record number, which we compute explicitly. We also show that an interesting scaling limit emerges when $p \to 1$, $N \to \infty$ with the product $t = (1-p)\, N$ fixed. We compute exactly the associated universal scaling functions for the mean, variance and the Fano factor of the number of records in this scaling limit. .

description: In this work, near-field imaging by two strongly coupled arrays of split ring resonators is analyzed. A simple theoretical model is developed to obtain the transfer function of the lens. This model shows that magnetoinductive surface waves (MISWs) play the same role as plasmon-polaritons in negative refractive slabs. In particular, the model predicts that the image is formed near the resonant frequency of the rings, between the pass-bands for the two MISW branches that can be excited in the lens. It also predicts a significant image enhancement when the distance between the source source and the image plane is smaller than twice the lens width. The predictions of the theoretical model are supported by measurements in the radio-frequency range. This suggests the possibility of using this kind of devices to imaging processes in the megahertz range, as for example in magnetic resonance imaging.

description: In this paper a notion of entropy transmission of quantum channels is introduced as a natural extension of Ohya's entropy. Here by quantum channel is meant unital completely positive mappings (ucp) of $B(H)$ into itself, where $H$ is an infinite dimensional Hilbert space. Using a representation theorem of ucp mapping we associate to every ucp map a uniquely determined state, and prove that entropy of ucp map is less then Ohya's entropy of the associated state.

description: We report enhanced nonlinear optics in complementary metal oxide semiconductor compatible photonic platforms through the use of layered two dimensional (2D) graphene oxide (GO) films. We integrate GO films with silicon on insulator nanowires (SOI), high index doped silica glass (Hydex) and silicon nitride (SiN) waveguides and ring resonators, to demonstrate an enhanced optical nonlinearity including Kerr nonlinearity and four wave mixing (FWM). The GO films are integrated using a large area, transfer free, layer by layer method while the film placement and size are controlled by photolithography. In SOI nanowires we observe a dramatic enhancement in both the Kerr nonlinearity and nonlinear figure of merit (FOM) due to the highly nonlinear GO films. Self phase modulation (SPM) measurements show significant spectral broadening enhancement for SOI nanowires coated with patterned films of GO. The dependence of GO Kerr nonlinearity on layer number and pulse energy shows trends of the layered GO films from 2D to quasi bulk like behavior. The nonlinear parameter of GO coated SOI nanowires is increased 16 fold, with the nonlinear FOM increasing over 20 times to a FOM greater than 5. We also observe an improved FWM efficiency in SiN waveguides integrated with 2D layered GO films. FWM measurements for samples with different numbers of GO layers and at different pump powers are performed, achieving up to 7.3 dB conversion efficiency (CE) enhancement for a uniformly coated device with 1 layer of GO and 9.1 dB for a patterned device with 5 layers of GO. These results reveal the strong potential of GO films to improve the nonlinear optics of silicon, Hydex and SiN photonic devices.

description: We present 432 low-dispersion optical spectra of 32 Type Ia supernovae (SNe Ia) that also have well-calibrated light curves. The coverage ranges from 6 epochs to 36 epochs of spectroscopy. Most of the data were obtained with the 1.5m Tillinghast telescope at the F. L. Whipple Observatory with typical wavelength coverage of 3700-7400A and a resolution of ~7A. The earliest spectra are thirteen days before B-band maximum; two-thirds of the SNe were observed before maximum brightness. Coverage for some SNe continues almost to the nebular phase. The consistency of the method of observation and the technique of reduction makes this an ideal data set for studying the spectroscopic diversity of SNe Ia.

description: This study presents an approach for fabricating durable superhydrophobic surfaces on 3D-printed structures inspired by the architectural design of beehives. Using fused deposition modeling (FDM) 3D printing technology, hexagonal macrostructures were fabricated using polylactic acid (PLA) filament. These structures were designed to protect an inner layer of hydrophobic nanoparticles, which were deposited by a squeegee coating method and immobilized by a photocurable resin. The relationship between hexagonal area size (ranging from 24 to 200 mm2) and the durability of superhydrophobic properties under frictional stress was systematically investigated. Wettability and surface morphology analyses performed before and after the friction tests showed that structures with hexagonal areas between 40 and 80 mm2 retained superhydrophobicity even after 100 friction cycles, while larger hexagonal configurations exhibited diminished performance. To elucidate the underlying mechanisms, a theoretical model based on the Cassie-Baxter equation was developed and compared with experimental values alongside surface observations. This research advances the development of durable and functional superhydrophobic surfaces in 3D-printed materials, with promising implications for industries requiring water-repellent and self-cleaning technologies. The study introduces an approach to creating durable superhydrophobic surfaces combining hydrophobic nanoparticles protected by 3D-printed hexagonal macrostructures inspired by beehive architecture, enhancing durability while maintaining superhydrophobicity under mechanical stress.

Subjects: smartphone application, seniors, mobility needs,

description: This report focuses on the development of a mobile smartphone application, named Urban Connector, to fill the gap, i.e., caters to the specific needs of seniors. To identify the mobility needs, a survey was conducted (in English and Spanish) at various senior recreation centers across El Paso, Texas. Questions were asked to 458 seniors to gain a better understanding of the lifestyle, mobility needs, and technological literacy (especially the use of smartphones). A similar survey on 61 seniors was conducted in New York, New York. It was discovered from the survey that the greatest mobility need of the seniors is that they would like to avoid traffic congestion. Although there is a market for smartphone application (i.e. many seniors own a smartphone), they are not using available navigation tools to avoid such traffic congestion. Therefore, the primary focus of the Urban Connector is navigation. The survey results provided guidelines on the functions and user interface designs. After the initial version of the Urban Connector had been developed in the Android platform, a pilot survey was conducted in which 65 seniors were asked to comment on the suitability of the functions, and ease of use (user interface and menu). Based on the feedbacks, the Urban Connector application was improved and refined. A follow up usability survey was implemented as the third effort to collect user feedbacks. In this usability survey, 40 seniors were recruited and they installed the Urban Connector application in their Android based smartphones to field test the application for one month. At the end of one month, 38 participants completed this survey.

description: Gastrointestinal (GI) parasitism is a health and production concern in sheep, yet its impact on animal welfare remains unclear. The impact of subclinical infections is especially ambiguous as GI parasitism often remains undiagnosed until clinical signs such as diarrhoea are evident. This study applied quantitative and qualitative methods to examine the effects of subclinical Teladorsagia circumcincta infection on the behaviour and welfare of 96 Suffolk-cross lambs (24 pens of 4 lambs) weaned at 10 weeks old. The hypothesis that parasitism causes negative affective states was tested. Lambs were divided into three groups at the pen level: ad-lib fed control (AC), restricted-fed control (RC), and ad-lib fed parasitised (AP). Parasitised lambs (AP) were dosed three times weekly with 7000 third stage T. circumcincta larvae (L 3) from 16 weeks of age. Lambs in the RC group were pair fed to match AP feed intake to separate the effects of infection-induced anorexia from the potential direct impacts of infection. From 7 days pre-infection to 23 days post-infection, scan and behaviour samples were taken from video recordings to quantitatively monitor behaviour, and animal-based measures such as faecal soiling score (FSS) were recorded as welfare indicators. Lying, standing, eating, play and social behaviour were monitored. Qualitative behaviour assessment (QBA) was conducted weekly using the AWIN (2015) protocol to gain insight into the lambs’ affective states over the onset of infection. Parasitised lambs were more likely to stand inactive than AC lambs as the infection progressed (P=0.006). They were also less likely to display eating behaviour in the third daily scan sample than RC lambs (P<0.001). Principal Component Analysis of the QBA data revealed that the first dimension (PC1) described arousal levels, the second (PC2) described the valence of the animals’ affective states, and the third (PC3) described fearfulness and aggression levels. Parasitised lambs (est=10.64,SE=0.33) scored higher than RC lambs (est=9.42, SE=0.33) on PC3, the fearfulness dimension (P=0.030). There were no differences between fearfulness scores of AC and AP lambs or RC lambs and treatment group had no significant impact on the distribution of scores on PC1 or PC2. These findings demonstrate that subclinical GI parasitism negatively impacts lamb welfare not only in the health domain but in the behaviour and mental domains as well. This has implications for welfare assessments and early disease detection in lambs. Future research could explore remote monitoring of the indicators of parasitism identified in this study.
Soil fauna communities in cedar-hemlock and hemlock-amabalis fir forest types on northern Vancouver Island, British Columbia
Creators: name: Battigelli, Jeffrey Paul
Publisher: name: University of British Columbia
Year: 2008

description: Soil fauna play an important role in regulating decomposition and nutrient cycling. They are able to process a portion of the annual litter input thus decreasing forest litter, increasing microbial activity and increasing mineralization of nutrients. The faunal composition of most Canadian soils has not been investigated. The purpose of this study is to determine and compare the composition of major soil fauna groups in Cedar-Hemlock and Hemlock-Amabalis fir forest types and to examine seasonal changes in vertical distribution within and between the forest types. Four methods were used to extract soil fauna: hand sorting, Lussenhop high gradient extractor, modified Baermann funnel and the Formalin method. Samplingoccurred five times between August 1989 and March 1991. Forty one groups were identified in both forest types. Results indicate that the Hemlock-Amabalis fir forest type maintains a higher abundance and biomass of soil fauna than the Cedar-Hemlock forest type. Nematoda are numerically dominant inboth forest types followed by Acari (in toto), Collembola (in toto) and Copepoda. Diplopoda, Enchytraeidae, Diptera larvae and Acari (in toto) are the dominant groups in both forest types when considering biomass. Similarity indices indicate that the forest types have similar group diversity. Biomass is slightly different between both forest types in October 1990. Analysis of variance performed on mean depth values for twenty groups indicate that mean depth was not significantly different between the two forest types (p > 0.05). Variation in mean depth was significantly different between sampling times for Prostigmata,Isotomidae, Onychiuridae and Nematoda (p > 0.05). Soil moisture content did not significantly affect mean depths. Distribution through the organic horizons showed a decrease in percent abundance of microarthropods in the upper organic layer in the summer with higher abundances in the spring and fall. Enchytraeidae showed a similar pattern in both forest types. Soil moisture content in the mat complex also exhibited this pattern with high moisture contents relating to higher abundances. Nematoda maintained a constant abundance in the upper organic layer throughout the study. This suggests that soil moisture may not be solely responsible for the observed shifts in vertical distribution of the groups examined. Overall, the soil fauna communities are similar between the Cedar-Hemlock and Hemlock-Amabalis fir forest types. Further work is required to increase the level of taxonomy to genus or species, which may identify tax a unique to either forest type. At the very least, this could provide a higher resolution of the distributional trends that might also be observed in species within the organic horizons and possibly relate information on their biological activity within these horizons.

In the case where $G$ is soluble we obtain a better result -- if $G$ is a finite soluble group in which every nilpotent subgroup generated by $w$-values is of rank at most $r$, then the rank of $w(G)$ is at most $r+1$.

The geochemistry and minerology of estuarine sediments : implications for Rice Grass removal in the Rubicon Estuary
Creators: name: Knight, EP
Publisher: name: University of Tasmania
Year: 2024

description: Saltmarshes are incredibly valuable ecosystems which support large ecosystems of fish, birds and plants, they provide a buffer between marine, terrestrial and riverine environments (Sheehan and Ellison, 2015). The aim of this study was to assess the risks associated with a large-scale removal of Spartina anglica from the Rubicon estuary in central northern Tasmania. The removal of this invasive species would allow hectares of sediment to remobilise into the surface waters of the estuary and any metals currently held in the sediment would be mobile and could become toxic to the ecosystem. The results of the study showed elevated levels of Cu and Zn in the surface waters, with Cu being above ANZECC guidelines. The sediment also showed elevated metals, particularly Al, Cu, Cr, Fe, Ni, Pb, Ti and Zn, these metals of concern were the focus of the study. It was found that although metals were elevated in the sediment, they were held in immobile mineral phases which are unlikely to enter the ecosystem, such as the high proportion of Ti that was found to be held in ilmenite and rutile. The shaker flask testing resulted in metals being resorbed into the sediment rather than releasing into the surface waters. This study demonstrated that a large-scale eradication of Spartina anglica from the Rubicon estuary is unlikely to cause a mass remobilisation of metals into the estuary. This suggests that removing the invasive grass will have an overall positive benefit to the ecosystem.

Data from the Far Ultraviolet Spectroscopic Explorer (FUSE) were used to analyze 26 lines of sight lying both in the galactic disk and halo, including lines to Wolf-Rayet stars and through known supernova remnants. The equivalent widths of fluorine resonance lines at 951.871 A and 954.827 A were measured or assigned upper limits and combined with a nitrogen curve of growth to obtain F I column densities. These column densities were then used to calculate fluorine depletions. Comparisons are made to the previous study of F I by Federman et al. (2005) and implications for F I formation and depletion are discussed.

description: Compressive lensless imagers enable novel applications in an extremely compact device, requiring only a phase or amplitude mask placed close to the sensor. They have been demonstrated for 2D and 3D microscopy, single-shot video, and single-shot hyperspectral imaging; in each of these cases, a compressive-sensing-based inverse problem is solved in order to recover a 3D data-cube from a 2D measurement. Typically, this is accomplished using convex optimization and hand-picked priors. Alternatively, deep learning-based reconstruction methods offer the promise of better priors, but require many thousands of ground truth training pairs, which can be difficult or impossible to acquire. In this work, we propose the use of untrained networks for compressive image recovery. Our approach does not require any labeled training data, but instead uses the measurement itself to update the network weights. We demonstrate our untrained approach on lensless compressive 2D imaging as well as single-shot high-speed video recovery using the camera's rolling shutter, and single-shot hyperspectral imaging. We provide simulation and experimental verification, showing that our method results in improved image quality over existing methods.

description: The Simon tensor gives rise to a local characterization of the Kerr-NUT family in the stationary class of vacuum spacetimes. We find that a symmetric and traceless tensor in the quotient space of the stationary Killing trajectory offers a useful alternative to the Simon tensor. Our tensor is distinct from the spatial dual of the Simon tensor and illustrates the geometric property of the three dimensional quotient space more manifest. The reconstruction procedure of the metric for which the generalized Simon tensor vanishes is spelled out in detail. We give a four dimensional description of this tensor in terms of the Coulomb part of the imaginary selfdual Weyl tensor, which corresponds to the generalization of the three-index tensor defined by Mars. This allows us to establish a new and simple criterion for the Kerr-NUT family: the gradient of the Ernst potential becomes the non-null eigenvector of the Coulomb part of the imaginary selfdual Weyl tensor. We also discuss the ${\rm SU}(1,2)$ covariant extension of the obstruction tensor into the Einstein-Maxwell system as an intrinsic characterization of the Kerr-Newman-NUT family.

The integrals reduce to those over the maximal tori by semi-classical approximation which is exact in reduced models. We carry out residue calculus by developing a diagrammatic method, in which the action of the Weyl groups and therefore counting of multiplicities are explained obviously.

description: Anomia (word-finding difficulties) is the hallmark of aphasia, an acquired language disorder most commonly caused by stroke. Assessment of speech performance using picture naming tasks is a key method for both diagnosis and monitoring of responses to treatment interventions by people with aphasia (PWA). Currently, this assessment is conducted manually by speech and language therapists (SLT). Surprisingly, despite advancements in automatic speech recognition (ASR) and artificial intelligence with technologies like deep learning, research on developing automated systems for this task has been scarce. Here we present NUVA, an utterance verification system incorporating a deep learning element that classifies 'correct' versus' incorrect' naming attempts from aphasic stroke patients. When tested on eight native British-English speaking PWA the system's performance accuracy ranged between 83.6% to 93.6%, with a 10-fold cross-validation mean of 89.5%. This performance was not only significantly better than a baseline created for this study using one of the leading commercially available ASRs (Google speech-to-text service) but also comparable in some instances with two independent SLT ratings for the same dataset.

description: The instability of metal halide perovskites upon exposure to moisture or heat strongly hampers their applications in optoelectronic devices. Here, we report the large-yield synthesis of highly water-resistant total-inorganic green luminescent CsPbBr3/CsPb2Br5 core/shell heteronanocrystals (HNCs) by developing an in situ phase transition approach. It is implemented via water-driven phase transition of the original monoclinic CsPbBr3 nanocrystal and the resultant tetragonal CsPb2Br5 nanoshell has small lattice mismatch with the CsPbBr3 core, which ensures formation of an epitaxial interface for the yielded CsPbBr3/CsPb2Br5 HNCs. These HNCs maintain nearly 100% of the original luminescence intensity after immersion in water for eleven months and the luminescence intensity drops only to 81.3% at 100 °C. The transient luminescence spectroscopy and density functional theory calculation reveal that there are double radiative recombination channels in the core CsPbBr3 nanocrystal, and the electron potential barrier provided by the CsPb2Br5 nanoshell significantly improves the exciton recombination rate. A prototype quasi-white light-emitting device based on these robust CsPbBr3/CsPb2Br5 HNCs is realized, showing their strong competence in solid-state lighting and wide color-gamut displays.

description: Quantum phase transitions (QPTs) are usually associated with many-body systems with large degrees of freedom approaching the thermodynamic limit. In such systems, the many-body ground state shows abrupt changes at zero temperature when the control parameter of the Hamiltonian is scanned across a quantum critical point. Recently it has been realized that a QPT can also occur in a simple system composed of only a two-level atom and a single-mode bosonic field, described by the quantum Rabi model (QRM). Here we report the first experimental demonstration of a QPT in the QRM using a single trapped ion. We measure the average spin-up state population of the ion and the average phonon number in its spatial oscillation mode as two order parameters and observe the clear evidences of the phase transition via slow quench of the coupling between the ion and its spatial motion. An experimental probe of the phase transitions in a fundamental quantum optics model without imposing the thermodynamic limit opens up a new window for the controlled study of QPTs and quantum critical phenomena.

description: We study the steady state of the two-species Asymmetric Simple Exclusion Process (ASEP) with open boundary conditions. The matrix product method works for the determination of the stationary probability distribution. Several physical quantities are calculated through an explicit representation for the matrix products. By making full use of the relation with the continuous big q-Hermite polynomials, we arrive at integral formulae for the partition function and the n-point functions. We examine the thermodynamic limit and find three phases: the low-density phase, the high-density phase and the maximal current phase.

description: We extend the definition, from the class of abelian groups to a general locally compact group G, of Feichtinger's remarkable Segal algebra S_0(G). In order to obtain functorial properties for non-abelain groups, in particular a tensor product formula, we endow S_0(G) with an operator space structure. With this structure S_0(G) is simultaneously an operator Segal algebra of the Fourier algebra A(G), and of the group algebra L^1(G). We show that this operator space structure is consistent with the major functorial properties: (i) S_0(G)\hat{\otimes}S_0(H)=S_0(G\times H) completely isomorphically (operator projective tensor product), if H is another locally compact group; (ii) the restriction map u\mapsto u|_H:S_0(G)\to S_0(H) is completely surjective, if H is a closed subgroup; and (iii) T_N:S_0(G)\to S_0(G/N) is completely surjective, where N is a normal subgroup and T_N u(sN)=\int_N u(sn)dn. We also show that S_0(G) is an invariant for G when it is treated simultaneously as a pointwise algebra and a convolutive algebra.

description: Recently, the single image super-resolution (SISR) approaches with deep and complex convolutional neural network structures have achieved promising performance. However, those methods improve the performance at the cost of higher memory consumption, which is difficult to be applied for some mobile devices with limited storage and computing resources. To solve this problem, we present a lightweight multi-scale feature interaction network (MSFIN). For lightweight SISR, MSFIN expands the receptive field and adequately exploits the informative features of the low-resolution observed images from various scales and interactive connections. In addition, we design a lightweight recurrent residual channel attention block (RRCAB) so that the network can benefit from the channel attention mechanism while being sufficiently lightweight. Extensive experiments on some benchmarks have confirmed that our proposed MSFIN can achieve comparable performance against the state-of-the-arts with a more lightweight model.

description: This thesis presents the aerodynamic analysis of a UAV with a BWB configuration. The analysis has been performed using the open source CDF software OpenFOAM®. OpenFOAM® requires for the user to have a basic knowledge of C++ programming, Linux environment and a solid background in the physics of the problem. Thus, the governing equations of fluid dynamics and their numerical solution via the FVM should be introduced before the OpenFOAM® case structure analysis. The next part of the thesis is the BWB UAV design based on the conclusions of the previous studies and the distinctive aerodynamic characteristics and limitations of the BWB configurations. Then, the CAD model was analyzed in OpenFOAM® and crucial insights were gained which led to the redesign of the UAV. Subsequently, a final BWB UAV layout, which fulfils the requirements and is statically stable in pitching and yawing axes, was developed. Finally, the performance of the added winglets was evaluated and it was found that the winglets can improve the overall efficiency of the UAV.

Η συγκεκριμένη ανάλυση πραγματοποιήθηκε με τη χρήση του ανοιχτού λογισμικού υπολογιστικής ρευστομηχανικής OpenFOAM®. Η χρήση του λογισμικό OpenFOAM® απαιτεί βασικές γνώσεις της γλώσσας προγραμματισμού C++, του περιβάλλοντος Linux καθώς και της θεωρίας της υπολογιστικής ρευστομηχανικής. Συνεπώς, πρέπει να γίνει μία εισαγωγή στις θεμελιώδης εξισώσεις της ρευστομηχανικής και την αριθμητική επίλυση τους μέσω της μεθόδου των πεπερασμένων όγκων, πριν αναλυθεί το περιεχόμενο μίας περίπτωσης του OpenFOAM®. Το επόμενο μέρος της διπλωματικής εργασίας περιλαμβάνει την σχεδίαση ενός μη επανδρωμένου αεροσκάφους με τη διαμόρφωση της ιπτάμενης πτέρυγας, βάση, των συμπερασμάτων των προηγούμενων εργασιών και των ιδιαίτερων χαρακτηριστικών αλλά και των περιορισμών της διαμόρφωσης της ιπτάμενης πτέρυγας. Στη συνέχεια, το σχέδιο σε μορφή CAD που προέκυψε, αναλύθηκε μέσω του OpenFOAM® και η ανάλυση των αποτελεσμάτων οδήγησε στην ανάγκη επανασχεδίασης του αεροσκάφους. Ως εκ τούτου, σχεδιάστηκε ένα νέο μη επανδρωμένο αεροσκάφος με τη διαμόρφωση της ιπτάμενης πτέρυγας που καλύπτει τις απαιτήσεις και είναι στατικά ευσταθές στην πρόνευση και την εκτροπή. Τέλος, μελετήθηκε η απόδοση των winglets και βρέθηκε ότι μπορούν να αυξήσουν την συνολική απόδοση του αεροσκάφους.

description: In this paper, we focus on the supersymmetric model with left-right (LR) symmetry, that is especially proposed in our previous work [1]. In this model, there are four Higgs doublets in order to realize the Standard Model (SM) fermion masses and the Cabibbo-Kobayashi-Maskawa matrix. The heavy Higgs doublets unavoidably have flavor changing couplings to the SM fermions and induce flavor-changing neutral currents at tree level. We study broader parameter space than the previous work with including the renormalization group corrections to the Yukawa couplings between the LR breaking scale, $\mathcal{O}(10^{13})$ GeV, and the supersymmetry breaking scales, $\mathcal{O}(100)$ TeV. The CP violating observable in $K$-$\overline{K}$ mixing, $ε_K$, strongly constrains the model, so that heavy Higgs mass should be heavier than $\mathcal{O}(100)$ TeV. We study the lepton flavor violating (LFV) processes setting heavy Higgs masses to be 170 TeV. The branching ratios of $μ\to 3 e$ and the $μ$-$e$ conversion can be larger than $10^{-16}$ that could be covered by the future experiments. We also study the degree of fine-tuning in the parameter region that predicts testable LFV processes.

description: The distribution of recurrence times or return intervals between extreme events is important to characterize and understand the behavior of physical systems and phenomena in many disciplines. It is well known that many physical processes in nature and society display long range correlations. Hence, in the last few years, considerable research effort has been directed towards studying the distribution of return intervals for long range correlated time series. Based on numerical simulations, it was shown that the return interval distributions are of stretched exponential type. In this paper, we obtain an analytical expression for the distribution of return intervals in long range correlated time series which holds good when the average return intervals are large. We show that the distribution is actually a product of power law and a stretched exponential form. We also discuss the regimes of validity and perform detailed studies on how the return interval distribution depends on the threshold used to define extreme events.
