description: Society lacks a thorough understanding of the concept of aging. By the time Americans reach their senior years, they have little concept of what life will become as an aging adult. Older adults begin to grow isolated from society both physically and mentally. Health limitations, technological or transportation limitations, and spatial discrepancies generate barriers to seniors, perpetuating a cycle of isolation and loneliness. As the senior population rapidly increases with the aging of Baby Boomers, can architecture break this cycle and stimulate the creation of a society of intertwined generations? This thesis challenges the design of senior housing to become a vehicle through which seniors might reconnect with society through intellectual, physical, and social engagement. Designing spaces that foster new paradigms of intergenerational relationships may become the tool through society is exposed to the beauty and importance of aging.

description: We present a complete analytical solution of a system of Potts spins on a random k-regular graph in both the canonical and microcanonical ensembles, using the Large Deviation Cavity Method (LDCM). The solution is shown to be composed of three different branches, resulting in an non-concave entropy function.The analytical solution is confirmed with numerical Metropolis and Creutz simulations and our results clearly demonstrate the presence of a region with negative specific heat and, consequently, ensemble inequivalence between the canonical and microcanonical ensembles.

Debris torrent mechanisms
Creators: name: Smyth, Kenneth Jeffrey
Publisher: name: University of British Columbia
Year: 2010

description: The phenomenon of the debris torrent is explored by examining the mechanisms of initiation, particularly those of rainfall and deforestation. The types of precipitation likely to contribute to instability are identified and data collection is reviewed. Debris torrents have characteristics unlike that of ordinary stream flow, and are capable of transporting massive quantities and sizes of material. Models to explain this transport capability are compared and contrasted. A theoretical analysis of the flow regime is carried out which is argued to be consistent with the observed turbulent nature of a debris torrent. This analysis is extended to the calculation of superelevation in bends and shows that current attempts to estimate velocities from super-elevation data may be very conservative. Further application of the turbulent stress analysis is used to estimate the angle of spread of the debris torrent in the deposition zone, and this analysis may be useful in zoning the downstream area to safeguard construction.

description: Mobility, whether for studies or internships, is considered one of the most important EU actions in the field of education and a key tool for achieving the broader goal of European integration. The fact that mobility at various levels (students, university professors, primary and secondary school teachers and teachers, school students, etc.) is institutionally organized and supported by European grants reflects - and is treated as - an "investment" in European education, closely linked to the emergence of common standards and an emphasis on competitiveness in view of the requirements of the single market. Ιt is a commonplace that, Erasmus program is a political initiative and a symbol for this new generation of European citizens, a brand name known worldwide. This paper analyzes the essential involvement of European exchange programs in the formation of a European identity and examines through a questionnaire to students and graduates of the Aristotle University of Thessaloniki, to what extent the Erasmus mobility program affected them at an academic, professional and personal level. AUTH is constantly active in the various actions of the Erasmus program supporting both incoming and outgoing users.

description: The U.S. Department of State deploys hundreds of American diplomats into embassies abroad. With temporary posts, diplomats and their families are transplanted into unfamiliar, foreign contexts. While protecting Americans abroad, this mobile and dynamic population attempts to find stability and security in a temporary environment. This thesis examines the crossroads of culture and architecture through the implementation of a new United States embassy in Algiers, Algeria. As diplomats and locals attempt to absorb one another’s culture, they can face a sense of displacement. U.S. embassies can expand from a purely political context to one that creates community between Americans and Algerians. It explores the built environment’s role in mitigating physical and social displacement and maintaining security. With globalization, preserving identity while blurring the boundaries between cultures becomes a challenge. By integrating community, foreign policy and security, architecture can create a platform for cultural assimilation resulting in a truly global society.
Subleading contributions to the decay width of the $T_{cc}^+$ tetraquark

description: Recently the LHCb collaboration has announced the discovery of the $T_{cc}^+$ tetraquark. Being merely a few hundred ${\rm keV}$ below the $D^{*+} D^0$ threshold, the $T_{cc}^+$ is expected to have a molecular component, for which there is a good separation of scales that can be exploited to make reasonably accurate theoretical predictions about this tetraquark. Independently of its nature, the most important decay channels will be $D^+ D^0 π^0$, $D^0 D^0 π^+$ and $D^+ D^0 γ$. Its closeness to threshold suggests that the mass and particularly the width of the $T_{cc}^+$ tetraquark depend on the resonance profile. While the standard Breit-Wigner parametrization generates a $T_{cc}^+$ that is too broad for current theoretical calculations to reproduce, a three-body unitarized Breit-Wigner shape reveals instead a decay width ($Γ_{\rm pole} = 48\pm 2\,{}^{+0}_{-12}\,{\rm keV}$) consistent with theoretical expectations. Here we consider subleading order contributions to the decay amplitude, which though having at most a moderate impact in the width still indicate potentially significant differences with the experimental width that can be exploited to disentangle the nature of the $T_{cc}^+$. Concrete calculations yield $Γ^{\rm LO} = 49 \pm 16\,{\rm keV}$ and $Γ^{\rm NLO} = 58^{+7}_{-6}\,{\rm keV}$, though we expect further corrections to the ${\rm NLO}$ decay widths from asymptotic normalization effects. We find that a detailed comparison of the ${\rm NLO}$ total and partial decay widths with experiment suggests the existence of a small (but distinguishable from zero) non-molecular component of the $T_{cc}^+$.

description: Cellular appendages conferring motility, such as flagella or cilia, are known to synchronise their periodic beats. The origin of synchronisation is a combination of long-range hydrodynamic interactions with physical mechanisms allowing the phases of these biological oscillators to evolve. Two of such mechanisms have been identified by previous work, the elastic compliance of the periodic orbit or oscillations driven by phase-dependent biological forcing. To help uncover the physical mechanism for hydrodynamic synchronisation most essential overall in biology, we theoretically investigate the effect of strong confinement on the effectiveness of hydrodynamic synchronisation. We use minimal models where appendages are modelled as rigid spheres forced to move along circular trajectories near a rigid surface. Strong confinement is modelled by adding a second nearby surface, parallel to the first one, where the distance between the surfaces is much smaller than the typical distance between the cilia. We calculate separately the impact of confinement on the synchronisation dynamics of the elastic compliance and the force modulation mechanisms and compare our results to the case with no confinement. Applying our results to the biologically-relevant situation of nodal cilia, we show that force modulation is a mechanism that leads to phase-locked states under strong confinement that are very similar to those without confinement as a difference with the elastic compliance mechanism. Our results point therefore to the robustness of force modulation for synchronisation, an important feature for biological dynamics that suggests it could be the most essential physical mechanism overall in arrays of nodal cilia. We further examine the distinct situation of primary cilia and show in that case that the difference in robustness of the mechanisms is not as pronounced but still favours the force modulation.

description: This paper presents a novel method for visualizing four-dimensional (4D) shapes using quantum computing, addressing challenges in traditional computing. The focus is on rendering a 4D hypercube (tesseract) via quantum algorithms. A specific quantum algorithm is developed, utilizing the Quantum Gate Model to encode 4D vertices in quantum states and form entanglements representing hypercube edges. The central technique is a projection transformation, executed using a custom unitary matrix. This matrix aims to condense the fourth dimension while preserving spatial relationships. The method's validity is confirmed through a mathematical proof, assessing vertex distance preservation in the hypercube before and after projection. An analysis of error rates evaluates the impact of gate errors, highlighting the limitations of current quantum computing hardware. The paper further explores algorithm optimization strategies to enhance efficiency and minimize errors. These findings underscore quantum computing's promising role in computer graphics, specifically in depicting complex, multidimensional data, marking a significant stride in the field.
On the occurrence of oscillatory modulations in the power-law behavior of dynamic and kinetic processes in fractals

description: The dynamic and kinetic behavior of processes occurring in fractals with spatial discrete scale invariance (DSI) is considered. Spatial DSI implies the existence of a fundamental scaling ratio (b_1). We address time-dependent physical processes, which as a consequence of the time evolution develop a characteristic length of the form $ξ\propto t^{1/z}$, where z is the dynamic exponent. So, we conjecture that the interplay between the physical process and the symmetry properties of the fractal leads to the occurrence of time DSI evidenced by soft log-periodic modulations of physical observables, with a fundamental time scaling ratio given by $τ= b_1 ^z$. The conjecture is tested numerically for random walks, and representative systems of broad universality classes in the fields of irreversible and equilibrium critical phenomena.

description: We present the number counts of Ks-band selected high redshift galaxy populations such as extremely red objects (EROs), B, z & K -band selected galaxies (BzKs) and distant red galaxies (DRGs) in the AKARI NEP field. The final catalogue contains 308 EROs (Ks<19.0 ; 54 percent are dusty star-forming EROs and the rest are passive old EROs), 137 star-forming BzKs and 38 passive old BzKs (Ks<19.0) and 64 DRGs (Ks<18.6). We also produce individual component source counts for both the dusty star-forming and passive populations. We compare the observed number counts of the high redshift passively evolving galaxy population with a backward pure luminosity evolution (PLE) model allowing different degrees of number density evolution. We find that the PLE model without density evolution fails to explain the observed counts at faint magnitudes, while the model incorporating negative density evolution is consistent with the observed counts of the passively evolving population. We also compare our observed counts of dusty star-forming EROs with a phenomenological evolutionary model postulating that the near-infrared EROs can be explained by the source densities of the far-infrared - submillimetre populations. Our model predicts that the dusty ERO source counts can be explained assuming a 25 percent contribution of submillimetre star-forming galaxies with the majority of brighter Ks -band detected dusty EROs having luminous (rather than HR10 type ultra-luminous) submillimetre counterparts. We propose that the fainter Ks>19.5 population is dominated by the sub-millijansky submillimetre population. We also predict a turnover in in dusty ERO counts around 19

description: A large acceptance scintillator detector with wavelength shifting optical fibre readout has been designed and built to detect the decay particles of $η$-nucleus bound system (the so-called $η$-mesic nuclei), namely, protons and pions. The detector, named as ENSTAR detector, consists of 122 pieces of plastic scintillator of various shapes and sizes, which are arranged in a cylindrical geometry to provide particle identification, energy loss and coarse position information for these particles. A solid angle coverage of $\sim$95% of total 4$π$ is obtained in the present design of the detector. Monte Carlo phase space calculations performed to simulate the formation and decay of $η$-mesic nuclei suggest that its decay particles, the protons and pions are emitted with an opening angle of 150$^\circ \pm 20^\circ$, and with energies in the range of 25 to 300 MeV and 225 to 450 MeV respectively. The detailed GEANT simulations show that $\sim$ 80 % of the decay particles (protons and pions) can be detected within ENSTAR. Several test measurements using alpha source, cosmic-ray muons etc. have been carried out to study the response of ENSTAR scintillator pieces. The in-beam tests of fully assembled detector with proton beam of momentum 870 MeV/c from the Cooler synchrotron COSY have been performed. The test results show that the scintillator fiber design chosen for the detector has performed satisfactorily well. The present article describes the detector design, simulation studies, construction details and test results.

description: The absolute generalized cross sections and angular distribution parameters of photoelectrons for the two-photon above threshold $3p$-ionization of Ar were calculated in the exciting photon energy range from 15.76 to 36 eV. The correlation function technique developed earlier was extended for the case when an intermediate-state function is of a continuum-type. We show that two-photon ionization of Ar near the $3p^{4}$ threshold to a large extent is determined by the $(3p\dashrightarrow\varepsilon d)^{2}$ two-photon absorption via the giant resonance. This many-electron correlation causes (i) an increase of the photoionization cross sections by more than a factor of 3; (ii) the appearance of resonances in the exciting-photon energy range of the doubly-excited states. The predictions are supported by a good agreement between length and velocity results obtained after taking into account of the higher-order perturbation theory corrections.

description: The search for the effect of private debt, i.e., the debt accumulated by individuals, households and private businesses, on the power of states and how this affects the role of the latter in the international political arena, is a particularly topical issue. The role of the capitalist system in today's global economy has not been negligible at all. Of course, and even though it is becoming clear that especially in the international political scene, the public debt of the states is the one that takes the lead, the importance of the private debt in the state power cannot be overlooked. Private debt is a beneficial and essential part of any economy and as long as it is at low levels it is possible to affect the production of a country in a positive way. However, as it increases, it can lead to economic crises and become an obstacle to the economic development of states, which will ultimately affect their position at the international level. A challenge in recent years has of course been the corona virus pandemic, which brought about dramatic consequences and a sharp increase in the private debt of the states, with subsequent consequences for their state power.

Exploring Reggeon bound states in strongly-coupled $\mathcal{N}=4$ super Yang-Mills

description: The multi-Regge limit of scattering amplitudes in strongly-coupled $\mathcal{N}=4$ super Yang-Mills is described by the large mass limit of a set of thermodynamic Bethe ansatz (TBA) equations. A non-trivial remainder function arises in this setup in certain kinematical regions due to excitations of the TBA equations which appear during the analytic continuation into these kinematical regions. So far, these analytic continuations were carried out on a case-by-case basis for the six- and seven-gluon remainder function. In this note, we show that the set of possible excitations appearing in any analytic continuation in the multi-Regge limit for any number of particles is rather constrained. In particular, we show that the BFKL eigenvalue of any possible Reggeon bound state is a multiple of the two-Reggeon BFKL eigenvalue appearing in the six-gluon case.

description: We discuss whether the bound nature of multiquark states in quark models could benefit from relativistic effects on the kinetic energy operator. For mesons and baryons, relativistic corrections to the kinetic energy lead to lower energies, and thus call for a retuning of the parameters of the model. For multiquark states, as well as their respective thresholds, a comparison is made of the results obtained with non-relativistic and relativistic kinetic energy. It is found that the binding energy is lower in the relativistic case. In particular, $QQ\bar q\bar q$ tetraquarks with double heavy flavor become stable for a larger ratio of the heavy to light quark masses; and the all-heavy tetraquarks $QQ\bar Q\bar Q$ that are not stable in standard non-relativistic quark models remain unstable when a relativistic form of kinetic energy is adopted

description: We report variability of the X-ray source, X-7, in NGC 6946, during a 60 ksec Chandra observation when the count rate decreased by a factor of ~1.5 in ~5000 secs. Spectral fitting of the high and low count rate segments of the light curve reveal that the simplest and most probable interpretation is that the X-ray spectra are due to disk black body emission with an absorbing hydrogen column density equal to the Galactic value of 2.1 X 10^{21} cm^{-2}. During the variation, the inner disk temperature decreased from ~0.29 to ~0.26 keV while the inner disk radius remained constant at ~6 X 10^8 cm. This translates into a luminosity variation from 3.8 to 2.8 X 10^{39} ergs cm^{-2} sec^{-1} and a black hole mass of ~400 solar masses. More complicated models like assuming intrinsic absorption and/or the addition of a power-law component imply a higher luminosity and a larger black hole mass. Even if the emission is beamed by a factor of ~5, the size of the emitting region would be > 2.7 X 10^8 cm implying a black hole mass > 180 solar masses. Thus, these spectral results provide strong evidence that the mass of the black hole in this source is definitely > 100 solar masses and more probably ~400 solar masses.

description: The low energy excitations of graphene can be described by a massless Dirac equation in two spacial dimensions. Curved graphene is proposed to be described by coupling the Dirac equation to the corresponding curved space. This covariant formalism gives rise to an effective hamiltonian with various extra terms. Some of them can be put in direct correspondence with more standard tight binding or elasticity models while others are more difficult to grasp in standard condensed matter approaches. We discuss this issue, propose models for singular and regular curvature and describe the physical consequences of the various proposals.

Counselling clients with foreign accents : a comparison of counsellor anxiety with the accented and non-accented client
Creators: name: Rungta, Susan A.
Publisher: name: University of British Columbia
Year: 2010

description: This research project was designed to determine whether anxiety in counsellors was higher with clients with foreign accents, and if so, whether this resulted in counsellors being less effective within the counselling session. Other feelings experienced by counsellors specific to counselling accented clients were also examined. Two separate, but related studies were conducted in which a comparison between two groups of counsellors-in-training was made. One group counselled a client with a European accent, while the other counselled a client with a Western Canadian speech style, typical of the region in which the study took place. Subjects in both groups were presented with a 20-minute video training tape of a client presenting a problem. Each subject was asked to respond verbally as they would in a real counselling session. The video tapes shown to the two groups were identical with the exception of the accent variable. The findings in both studies were similar. No statistically significant differences were found between the two groups in level of state anxiety as measured by the A-State of the STAI. Results from a questionnaire constructed specifically for this research project supported these findings. It did appear, however, that counsellors presented with the foreign accented client may have experienced more anxiety in the first few minutes of the session resulting from their inability to fully understand the accent. An unexpected finding emerged when both studies were examined together. It was found that a lower proportion of counsellors exposed to the foreign accented client expressed feelings on a frustrated/thwarted dimension (p<.05). More expected however, was the finding that higher levels of counsellor state anxiety were correlated with lower levels of counsellor functioning in the session (p<.001). The results of this study are discussed in relation to cross-cultural counselling, the anxiety-counsellor competence relationship, and sociolinguistic accent research. These results question several assumptions prevalent in the cross-cultural literature and suggest that a new set of issues may be emerging for the counsellor working with the minority client.

description: Excerpts: I shall not attempt in this brief summary to discuss progress in the whole broad field of social science. It seems to me more useful here to think of developments in the Department of Agriculture and the State colleges and universities than to wander too far afield. One cannot, as I have done in the past few years, examine the developments in the Department of Agriculture without being impressed by the great progress that has been made; in the improvement of basic data; in the development of analytical techniques and in the application of research findings to practical problems. My comment here refers principally to economic research. The economic studies and service work of the Department seem to me to fall roughly into three major categories: 1. The collection of basic data, here the Department has, in my opinion, made its greatest contribution. Without this enormous body of raw material for analytical work, most of the agricultural economics research both in and outside the Department would have been impossible. The United States now has a growing body of basic data that is incomparably better than that of any other nation in the world. 2. The Department has made a sizable contribution in the form of analytical studies. This phase of its work is less fully developed than its data gathering activities and perhaps always will be. The analytical work has, in my opinion, suffered a serious setback in the decision to break up the Bureau of Agricultural Economics. 3. There has been a very large development of what is sometimes called "operating research," that is, quick assembling of information needed in making administrative decisions, and rather rough and hurried analyses pertaining to some immediate problem. The trend in the last year or two, and perhaps in most of the years since 1930, has been in that direction.

Hydrodynamic interactions between ice masses and large offshore structures
Creators: name: Cheung, Kwok Fai
Publisher: name: University of British Columbia
Year: 2010

description: The objective of the work described in this thesis is to evaluate the significance of the ambient fluid on the motion of an ice mass in the vicinity of an offshore structure and during the subsequent impact mechanism. Models for iceberg drift are first reviewed. The changes in flow field around an ice mass drifting in a current near an offshore structure are investigated by potential flow theory. The proximity effects and current interactions are generalized by introducing the added mass and convective force coefficients for the ice mass. A two-dimensional numerical model based on the boundary element method is developed to calculate these coefficients over a range of separation distances up to the point of contact. A numerical model based on ice properties and geometry is developed to simulate the impact force acting on the structure. Both the 'contact-point' added masses estimated in this thesis and the traditionally assumed far-field added masses are used in the impact model separately. The results from the two cases are compared and the crucial roles played by the ambient fluid during impact are discussed. Finally, a number of related topics is proposed for further studies.

description: Two-mode nonlinear interaction (second-harmonic and second-subharmonic generation) in a planar waveguide with a small periodic corrugation at the surface is studied. Scattering of the interacting fields on the corrugation leads to constructive interference that enhances the nonlinear process provided that all the interactions are phase matched. Conditions for the overall phase matching are found. Compared with a perfectly quasi-phase-matched waveguide, better values of squeezing as well as higher intensities are reached under these conditions. Procedure for finding optimum values of parameters for squeezed-light generation is described.

description: The stories and places we choose to preserve tell us who we are as a people. What does it say about ourselves when the stories that are associated with a particular place are ones that we wish to keep in the dark? As we look towards the future of preservation it has become clear that our perception of what is “significant” has shifted. Modern preservation has expanded to include tangible and intangible landscapes, environmental conservation, and more voices at the table. This thesis explores how to use preservation, storytelling, and sustainable practices to respond to places of difficult history and reclaim that space, while using Crownsville State Hospital as a model. The racial and systemic trauma experienced at the formerly racially segregated mental health facility permeated the campus grounds; not only does the community need to heal, the land does too.

description: Στην παρούσα εργασία εξετάζεται ο Ιερός Ναός των Αγίων Αθανασίου Ακακίου και Δαμασκηνού στο χωριό Λητή, αρμοδιότητας της Ιεράς Μητροπόλεως Λαγκαδά Λητής και Ρεντίνης. Σε ένα ευρύτερο πλαίσιο, η Λητή έχει αξιοσημείωτη παρουσία εντός της ιστορικής εξέλιξης, με αφετηρία την αρχαιότητα όταν και συγκαταλεγόταν μεταξύ των πιο μεγάλων πόλεων στη Μακεδονία. Αναφορές για την ύπαρξή της συναντώνται και κατά τη διάρκεια της Βυζαντινής Περιόδου. Χωρίς να μπορεί να προσδιοριστεί χρονικά το διάστημα εντός του οποίου εκχριστιανίστηκε, εκτιμάται ότι αυτό συνέβη παράλληλα με την Θεσσαλονίκη. Στο πλαίσιο απόδοσης τιμών και αναγνώρισης των Αγίων της Χριστιανικής θρησκείας, στο χωριό Λητή ανεγέρθη ο ναός του Αγίου Αθανασίου όπως στην πορεία και μετά την πραγματοποίηση αγιοκατάταξης και την αναγνώριση της αγιότητας δύο πρώην επισκόπων της περιοχής, ονομάστηκε Ιερός Ναός Αγίων Αθανασίου, Ακακίου και Δαμασκηνού. Ξεχωρίζει ιδιαίτερα για το εικονοστάσιό του το οποίο αναμφισβήτητα έχει μεγάλη ιστορική σημασία. Καταληκτικά επισημαίνεται ότι η ιστορία του έχει συνδεθεί με την ιστορία της Λητής και με τα έθιμα και τις παραδόσεις των ντόπιων. Συνεπώς αντιλαμβάνεται κανείς ότι γνωρίζοντας κανείς τις ιστορικές πτυχές ενός τόπου, στις οποίες συγκαταλέγονται και τα ορθόδοξα μνημεία του, διευρύνει τους ορίζοντές του και έτσι κυριαρχεί η αγάπη και εκτίμηση για τους ανθρώπους που φιλοξενούνται εκεί. 
description: In this work, the Holy Church of Saints Athanasios Akakios and Damascenes in the village of Liti, under the jurisdiction of the Holy Metropolis of Lagada Liti and Rentini, is examined. In a broader context, Liti has a remarkable presence within the historical development, starting from antiquity when it was counted among the largest cities in Macedonia. References to its existence are also found during the Byzantine Period. Without being able to determine the period during which it became Christian, it is estimated that this happened at the same time as Thessaloniki. In the context of honoring and recognizing the Saints of the Christian religion, the church of Agios Athanasios was erected in the village of Liti as in the process and after the canonization and the recognition of the sainthood of two former bishops of the area, it was named the Holy Church of Agios Athanasios, Akakios and Damascenes. It stands out especially for its iconography which undoubtedly has great historical importance. Finally, it is pointed out that its history has been linked to the history of Litis and to the customs and traditions of the locals. Therefore, one realizes that knowing the historical aspects of a place, which includes its Orthodox monuments, broadens one's horizons and thus the love and appreciation for the people who are hosted there prevails.

description: We consider the construction of the basic bundle gerbe on SU(n) introduced by Meinrenken and show that it extends to a range of groups with unitary actions on a Hilbert space including U(n), diagonal tori and the Banach Lie group of unitary operators differing from the identity by an element of a Schatten ideal. In all these cases we give an explicit connection and curving on the basic bundle gerbe and calculate the real Dixmier-Douady class. Extensive use is made of the holomorphic functional calculus for operators on a Hilbert space.

description: We analyze the role of the Allee effect, a positive correlation between population density and mean individual fitness, for ecological communities formed by a large number of species. Our study is performed using the generalized Lotka-Volterra model with random interactions between species. We obtain the phase diagram and analyze the nature of the multiple equilibria phase. Remarkable differences emerge with respect to the case of the logistic growth case, thus revealing the major role played by the functional response in determining aggregate behaviours of ecosystems.

description: Quantile regression is a flexible approach to assessing covariate effects on failure time, which has attracted considerable interest in survival analysis. When the dimension of covariates is much larger than the sample size, feature screening and variable selection become extremely important and indispensable. In this article, we introduce a new feature screening method for ultrahigh dimensional censored quantile regression. The proposed method can work for a general class of survival models, allow for heterogeneity of data and enjoy desirable properties including the sure screening property and the ranking consistency property. Moreover, an iterative version of screening algorithm has also been proposed to accommodate more complex situations. Monte Carlo simulation studies are designed to evaluate the finite sample performance under different model settings. We also illustrate the proposed methods through an empirical analysis.
Stochastic modeling in nanoscale biophysics: Subdiffusion within proteins
Creators: name: Kou, S. C.

description: Advances in nanotechnology have allowed scientists to study biological processes on an unprecedented nanoscale molecule-by-molecule basis, opening the door to addressing many important biological problems. A phenomenon observed in recent nanoscale single-molecule biophysics experiments is subdiffusion, which largely departs from the classical Brownian diffusion theory. In this paper, by incorporating fractional Gaussian noise into the generalized Langevin equation, we formulate a model to describe subdiffusion. We conduct a detailed analysis of the model, including (i) a spectral analysis of the stochastic integro-differential equations introduced in the model and (ii) a microscopic derivation of the model from a system of interacting particles. In addition to its analytical tractability and clear physical underpinning, the model is capable of explaining data collected in fluorescence studies on single protein molecules. Excellent agreement between the model prediction and the single-molecule experimental data is seen.
