description: Η ανίχνευση τοπικών κοινοτήτων αποτελεί μέθοδο της ανάλυσης κοινωνικών δικτύων, στη σύγχρονη ανάλυση δεδομένων. Στην εργασία αυτή πραγματοποιείται προσπάθεια αναγνώρισης κοινοτήτων γύρω από κοινότητες γονιδίων. Τα γονίδια αυτά είναι γνωστό από την βιβλιογραφία πως σχετίζονται με την εκδήλωση καρκίνου του μαστού, σε περίπτωση που υποστούν κάποια μετάλλαξη. Τα τελευταία χρόνια όλο και περισσότερες μελέτες διεξάγονται στο πεδίο αυτό, ωστόσο η εφαρμογή της ανάλυσης κοινωνικών δικτύων και ιδιαίτερα της ανίχνευσης τοπικών κοινοτήτων είναι σε πρώιμο στάδιο. Η μέθοδος αυτή γεννήθηκε από την ανάγκη ανάλυσης δυναμικών δικτύων μεγάλου μεγέθους. Στο πλαίσιο της ανάλυσης που πραγματοποιείται, σημαντικό μέρος καταλαμβάνει η προεπεξεργασία των δεδομένων αλλά και η υλοποίηση του αλγορίθμου LTE. H εργασία αυτή προσφέρει σημαντικές κατευθύνσεις όσον αφορά τις ιδιομορφίες των αλγορίθμων ανίχνευσης τοπικών κοινοτήτων, καθώς και του δικτύου αυτού καθεαυτού. Μετά από την εκτέλεση του αλγορίθμου σχηματίστηκαν κοινότητες γύρω από τα γονίδια τα οποία παρουσιάζουν επιστημονικό ενδιαφέρον. Στο μέλλον θα ήταν σημαντικό να εφαρμοστούν περισσότεροι αλγόριθμοι ανίχνευσης τοπικών κοινοτήτων, για την εξαγωγή ασφαλών αποτελεσμάτων σχετικά με την τοπολογία του δικτύου
description: Local community detection is a method of analyzing social networks in modern data analysis. This work attempts to identify communities in gene networks, which are already known, from the literature, to have a strong relation with breast cancer forms, if they undergo a mutation. In recent years, more and more studies have been conducted in this field. However, the implementation of social network analysis and in particular the detection of local communities is at an early stage and it was born because of the need to analyze large and dynamic networks. An important part of this analysis involves the pre-processing of data and the implementation of the LTE algorithm. This novel work provides important insights about the peculiarities of the local community detection algorithms. After the application of the LTE algorithm, local communities around the genes of interest were identified. In the future, more local community detection algorithms could be applied in this network, in order to obtain more insights about the topology of it

description: An analytic formula is given for the total scattering cross section of an electron and a photon at order $α^3$. This includes both the double-Compton scattering real-emission contribution as well as the virtual Compton scattering part. When combined with the recent analytic result for the pair-production cross section, the complete $α^3$ cross section is now known. Both the next-to-leading order calculation as well as the pair-production cross section are computed using modern multiloop calculation techniques, where cut diagrams are decomposed into a set of master integrals that are then computed using differential equations.

description: Kn-band images, unsharp-masked images, as well as major-axis and vertically- summed surface brightness profiles are presented for 30 edge-on spiral galaxies, most with a boxy or peanut-shaped (B/PS) bulge. Such galaxies have more complex morphologies than galaxies of other bulge types, more often showing (off-)centered X structures, secondary major-axis maxima and spiral-like structures. Those features are also observed in N-body simulations of barred discs and may trace the main bar orbit families. The surface brightness profiles of galaxies with a B/PS bulge are also more complex, with typically 3 or more clearly separated regions, including a flat intermediate region (Freeman Type II profiles). Those radial breaks offer evidence for bar-driven transfer of angular momentum and radial redistribution of material. The profiles also suggest a rapid variation of the scaleheight of the disc material, contrary to conventional wisdom but again as expected from vertical resonances and instabilities in barred discs. The steep inner region of the surface brightness profiles is often shorter than the isophotally thick part of the galaxies, itself always shorter than the flat region of the profiles. Contrary to the standard `bulge + disc' model, we thus propose that galaxies with a B/PS bulge are composed of a thin concentrated disc (a disc-like bulge) contained within a partially thick bar (the B/PS bulge) and a thin outer disc. The inner disc likely formed secularly through bar-driven processes and is responsible for the steep inner region of the surface brightness profiles, while the bar is responsible for the flat region and the thick complex morphological structures observed. Those components are strongly coupled dynamically and are formed mostly of the same (disc) material. [Abridged]

description: Crisis management is an increasingly emerging domain in modern times. Amidst the risk society, predictability, preparedness and planning of crisis management serve as high virtues. In this context, effective crisis management includes the communication of the risk and the crises as well. It is a fact that the latter can prove to be life – saving, while informing adequately and promptly the citizens and can lead to the prevention of the spread of the crisis’s consequences. We have to bear in mind, after all, that any crisis can lead to human losses. In view of the above, the predominant risk of the communication of a crisis is the transmission of incorrect information or rumors, which in combination with the need for immediate and rapid response to the crisis may lead to negative results. However, proper preparation alongside with the involvement of well trained personnel in crisis management and advance planning of actions are the desired solution for the mitigation of the crisis and the associated risks. The management of the bomb that was found in Kordelio and the emergence of the need to neutralize it while avoiding any losses and damages in three Municipalities of Thessaloniki are examined. The case study demonstrates the need for crisis management and effective communication of the crisis

description: What is architecture if you cannot see? How might we perceive if we ignore our dominant visual sense to focus on inputs from the senses that we rarely engage as we move through the built environment? How might architects design buildings to fully engage our senses? This thesis began to address that question through research including a literature search, analysis of examples of architecture for visually impaired users, and interviews with blind individuals and people who work with visually impaired people. This research informed the development of a set of principles for the design of built environments that enrich the ability to people along the spectrum from sighted to blind to navigate the spaces of their lives through multi-sensory perception. These principles are tested by application to the design of a building, a Creative Co-Lab, in which blind and sighted users come together on the Baltimore waterfront to learn collaboratively about the multi-sensory ways to perceive and create space, place, and objects without vision.

description: The focus of this thesis is the design and implementation of a community health project at a new school campus for 600 students in St. Louis Du Norde, Haiti. The design harvests and filters rainwater to drinking water standards, grows nutritional vegetable crops on secure rooftops, creates social space, and recycles old tires, plastic bottles and rice sacks that otherwise pose a massive solid waste problem in Haiti. The processes are also taught to the students so they can take and use the planters at home. The materials for building the growing containers and the growing media are all free and made from local wastes (tires, plastic bottles, rice sacks, manure, soil etc.). They are easy to build and free to construct making them accessible to even to the poorest and neediest families in Haiti. The idea is to develop easily replicable and desirable solutions to the basic health needs.
Proposal of a Geiger-type Single-Phase Liquid Xenon Time Projection Chamber as Potential Detector Technique for Dark Matter Direct Search

description: Dual phase time projection chamber using liquid xenon as target material is one of most successful detectors for dark matter direct search, and has improved the sensitivities of searching for weakly interacting massive particles by almost five orders of magnitudes in past several decades. However, it still remains a great challenge for dual phase liquid xenon time projection chamber to be used as the detector in next-generation dark matter search experiments ($\sim$ 50 tonne sensitive mass), in terms of reaching sufficiently high field strength for drifting electrons, and sufficiently low background rate. Here we propose a single phase liquid xenon time projection chamber with detector geometry similar to a Geiger counter, as a potential detector technique for future dark matter search, which trades off field uniformity for less isolated charge signals. Preliminary field simulation and signal reconstruction study have shown that such single phase time projection chamber is technically feasible and can have sufficiently good signal reconstruction performance for dark matter direct search.

description: The present thesis develops a framework for Health Care Management Systems using modern Model-Based Systems Engineering methodologies and applies it to Diabetes Mellitus. The desired architecture of such systems is described. Tests and interventions, including Health Care IT, used for Diabetes 2 diagnosis and treatment, are described and modeled. A Controlled Markov Chain model for the progression of Diabetes Mellitus with three states, three diagnostic tests, ten interventions, three patient types, is developed. Evaluation metrics for healthcare quality and associated costs are developed. Using these metrics and disease models, two methods for tradeoff analysis between healthcare quality and costs are developed and analyzed. One is an exhaustive Monte Carlo simulation and the other utilizes multi-criteria optimization with full state information. The latter obtains similar results as the former at a fraction of the time. Practical examples illustrate the powerful capabilities of the framework. Future research directions and extensions are described.

description: Decoherence-Free Subsystems (DFS) are a powerful means of protecting quantum information against noise with known symmetry properties. Although Hamiltonians theoretically exist that can implement a universal set of logic gates on DFS encoded qubits without ever leaving the protected subsystem, the natural Hamiltonians that are available in specific implementations do not necessarily have this property. Here we describe some of the principles that can be used in such cases to operate on encoded qubits without losing the protection offered by the DFS. In particular, we show how dynamical decoupling can be used to control decoherence during the unavoidable excursions outside of the DFS. By means of cumulant expansions, we show how the fidelity of quantum gates implemented by this method on a simple two-physical-qubit DFS depends on the correlation time of the noise responsible for decoherence. We further show by means of numerical simulations how our previously introduced "strongly modulating pulses" for NMR quantum information processing can permit high-fidelity operations on multiple DFS encoded qubits in practice, provided that the rate at which the system can be modulated is fast compared to the correlation time of the noise. The principles thereby illustrated are expected to be broadly applicable to many implementations of quantum information processors based on DFS encoded qubits.

description: We investigate "chimera" states in a ring of identical phase oscillators coupled in a time-delayed and spatially non-local fashion. We find novel "clustered chimera" states that have spatially distributed phase coherence separated by incoherence with adjacent coherent regions in anti-phase. The existence of such time-delay induced phase clustering is further supported through solutions of a generalized functional self-consistency equation of the mean field. Our results highlight an additional mechanism for cluster formation that may find wider practical applications.

description: Bosonic modes have wide applications in various quantum technologies, such as optical photons for quantum communication, magnons in spin ensembles for quantum information storage and mechanical modes for reversible microwave-to-optical quantum transduction. There is emerging interest in utilizing bosonic modes for quantum information processing, with circuit quantum electrodynamics (circuit QED) as one of the leading architectures. Quantum information can be encoded into subspaces of a bosonic superconducting cavity mode with long coherence time. However, standard Gaussian operations (e.g., beam splitting and two-mode squeezing) are insufficient for universal quantum computing. The major challenge is to introduce additional nonlinear control beyond Gaussian operations without adding significant bosonic loss or decoherence. Here we review recent advances in universal control of a single bosonic code with superconducting circuits, including unitary control, quantum feedback control, driven-dissipative control and holonomic dissipative control. Various approaches to entangling different bosonic modes are also discussed.

Year: 2006

description: This paper describes a fourth-order integration algorithm for the gravitational N-body problem based on discrete Lagrangian mechanics. When used with shared timesteps, the algorithm is momentum conserving and symplectic. We generalize the algorithm to handle individual time steps; this introduces fifth-order errors in angular momentum conservation and symplecticity. We show that using adaptive block power of two timesteps does not increase the error in symplecticity. In contrast to other high-order, symplectic, individual timestep, momentum-preserving algorithms, the algorithm takes only forward timesteps. We compare a code integrating an N-body system using the algorithm with a direct-summation force calculation to standard stellar cluster simulation codes. We find that our algorithm has about 1.5 orders of magnitude better symplecticity and momentum conservation errors than standard algorithms for equivalent numbers of force evaluations and equivalent energy conservation errors.

description: Environmental noise plays a key role in determining the efficiency of transport in quantum systems. However, disorder and localisation alter the impact of such noise on energy transport. To provide a deeper understanding of this relationship we perform a systematic study of the connection between eigenstate localisation and the optimal dephasing rate in 1D chains. The effects of energy gradients and disorder on chains of various lengths are evaluated and we demonstrate how optimal transport efficiency is determined by both size-independent, as well as size-dependent factors. By discussing how size-dependent influences emerge from finite size effects we establish when these effects are suppressed, and show that a simple power law captures the interplay between size-dependent and size-independent responses. Moving beyond phenomenological pure dephasing, we implement a finite temperature Bloch-Redfield model that captures detailed balance. We show that the relationship between localisation and optimal environmental coupling strength continues to apply at intermediate and high temperature but breaks down in the low temperature limit.

description: Collagen is the most abundant extracellular-matrix protein in mammals and the main structural and load-bearing element of connective tissues. Collagen networks show remarkable strain-stiffening properties which tune the mechanical functions of tissues and regulate cell behaviours. Linear and non-linear mechanical properties of in-vitro disordered collagen networks have been widely studied using rheology for a range of self-assembly conditions in recent years. However, a one to one correlation between the onset of macroscopic network failure and local deformations inside the sample is yet to be established in these systems. Here, using shear rheology and in-situ high-resolution boundary imaging, we study the yielding dynamics of in-vitro reconstituted networks of uncrosslinked type-I collagen. We find that in the non-linear regime, the differential shear modulus ($K$) of the network initially increases with applied strain and then begins to drop as the network starts to yield beyond a critical strain (yield strain). Measurement of the local velocity profile using colloidal tracer particles reveals that beyond the peak of $K$, strong strain-localization and slippage between the network and the rheometer plate sets in that eventually leads to a detachment. We generalize this observation for a range of collagen concentrations, applied strain ramp rates, as well as different network architectures obtained by varying the polymerization temperature. Furthermore, by fitting the stress vs strain data with a continuum affine network model, we map out a state diagram showing the dependence of yield-stain and -stress on the reduced persistence length and mesh size of the network. Our findings can have broad implications in tissue engineering, particularly, in designing highly resilient biological scaffolds.

description: Rapid quantitative analysis of single chiral amino acid (aa) was achieved using circular dichroism (CD) with data analysis by standard calibration curve. The absolute concentrations of D- and L-aas in enantiomeric mixtures were determined by CD and achiral liquid chromatography (LC) method. It is worth noting that CD and LC were used independently, not on-line LC/CD in this study. The errors of the experimental results were less than 10%. The method is also applicable to the quantification of non-aa chiral molecules, such as chiral nucleoside and chiral quinine. With this study, we provide a new method for the chiral quantitative analysis of enantiomeric aas mixtures.

description: The goal of my thesis is to improve the typical office building’s performance as well as the work place by re-imagining the zone of the building’s enclosure. My position is that building enclosures which are usually thin and flat wrappers could instead, be zones of space that serve multiple functions contribute positively to both the building’s interior and its performance. On the urban scale, a network of these buildings could have a large impact on the city. By rethinking what the enclosure could be, I hope to improve the relationships between the urban fabric and the building, the people working there. Building enclosures are not meant to be thin and flat wrappers, they are meant to be dynamic elements of the building that serve multiple functions that improve the surrounding environment.

Με τη βοήθεια της βιβλιογραφικής επισκόπησης μελετάται η έννοια του μουσειακού μάρκετινγκ και των εργαλείων του. Κατόπιν, παρατίθενται δύο μελέτες περιπτώσεων (case studies), του Ελληνικού Παιδικού Μουσείου της Αθήνας και του Μουσείου Παιδιών της Βοστώνης που εφαρμόζουν το σύγχρονο μοντέλο ολοκληρωμένης επικοινωνίας του μάρκετινγκ χρησιμοποιώντας έξι βασικά εργαλεία: τη διαφήμιση, τις δημόσιες σχέσεις, την ενεργοποίηση του ονόματος του οργανισμού, τις επικοινωνιακές χορηγίες, το ηλεκτρονικό και το άμεσο μάρκετινγκ, επεκτείνοντας το παραδοσιακό μοντέλο των 4Ps του McCarthy.

description: This thesis explores which of the marketing tools the modern museums use for advertising and promotion. With the help of literature review, the concept of museum marketing and its tools is studied. Afterwards, there are two case studies, the Hellenic Children's Museum and the Boston Children's Museum that apply the modern integrated communication marketing model, using six basic tools: Advertising, Public Relations, branding, Communication Sponsorships, e-marketing and Direct Marketing, extending McCarthy's traditional 4Ps model. The relevance attributed to each of these tools, and the way they are applied, are differentiated according to the size and dynamics of the two Children's Museums. The findings of this research suggest that B.C.M. stands as a model of communication policy, making effective use of marketing tools in order to attract the public, while the H.C.M. presents significant shortcomings in the marketing communication tools· thus it is crucial to devise a strategy and design a marketing plan, but unfortunately the experts do not currently exist. Therefore, there is a strong convergence between theory and practice and, at the same time, it is possible to pinpoint a basic core of actions which can lead to favorable outcomes for each cultural organization

description: We analyze the space-times admitting two shear-free geodesic null congruences. The integrability conditions are presented in a plain tensorial way as equations on the volume element $U$ of the time-like 2--plane that these directions define. From these we easily deduce significant consequences. We obtain explicit expressions for the Ricci and Weyl tensors in terms of $U$ and its first and second order covariant derivatives. We study the different compatible Petrov-Bel types and give the necessary and sufficient conditions that characterize every type in terms of $U$. The type D case is analyzed in detail and we show that every type D space-time admitting a 2+2 conformal Killing tensor also admits a conformal Killing-Yano tensor.

description: Energetic materials are materials which can release large amounts of energy in a short time interval. When the size of energetic materials is reduced from micro into nanoscale, the reactivity of energetic materials increases dramatically due to increase in intimate contact and faster mass and heat transfer. Finding an efficient way to synthesize energetic nanocomposites has become an import research topic. Here I demonstrate the use of electrospray methods to generate mesostructured microparticles containing nanomaterials and a gas generator. The system was designed for characterization of the size distribution as well as combustion properties. In this thesis, size distribution of the Al/NC mesoparticles is tuned from 0.7-2.0 µm, and the ignition delay is shown significantly decrease (15 ms to 3 ms) compared to nano-size Al. The burn time is also decreased significantly (4036 µs to 366 µs) by using electrospray assembly. This demonstrated that assembly of nanocomponents can significantly impact combustion performance.

description: We report on the design, fabrication, and on-sky performance of the Florida Image Slicer for Infrared Cosmology and Astrophysics (FISICA)- a fully-cryogenic all-reflective image-slicing integral field unit for the FLAMINGOS near-infrared spectrograph. Designed to accept input beams near f/15, FISICA with FLAMINGOS provides R \sim 1300 spectra over a 16x33-arcsec field-of-view on the Cassegrain f/15 focus of the KPNO 4-meter telescope, or a 6x12-arcsec field-of-view on the Nasmyth or Bent Cassegrain foci of the Gran Telescopio Canarias 10.4-meter telescope. FISICA accomplishes this using three sets of "monolithic" powered mirror arrays, each with 22 mirrored surfaces cut into a single piece of aluminum. We review the optical and opto-mechanical design and fabrication of FISICA, as well as laboratory test results for FISICA integrated with the FLAMINGOS instrument. Finally, we present performance results from observations with FISICA at the KPNO 4-m telescope and comparisons of FISICA performance to other available IFUs on 4-m to 8-m-class telescopes.

description: The present study discusses the insulation thickness effects on the underground oil pipeline life cycle overall costs and its sensitivity to economic parameters and environmental Emissions. The heating degree-day and life cycle cost procedures are used for the optimization and environmental analyses of the mazut oil pipeline. The insulation materials used are Rock wool, PF, and EPS regarding all the physical and economical parameters of insulation thickness. The results show that the optimum insulation thickness varies between 70.7 and 130.4 mm, the annual energy saving cost varies between 403.69 and 419.29 $/m, the payback periods vary between 0.331 and 0.887 years, the reductions in emissions at optimum insulation thickness marked 90.84% for Rock wool, 93.2% for PF, and 93.28% for EPS. Both lifetime and the unit cost of insulation is sensitive to the insulation thickness. Additionally, the increased discount rate and cost of insulation material per unit volume reduce the optimum insulation thickness. In conclusion, it is predictable that this research can supply a guide for engineers as insulation is used to decrease the total energy loss and total annual cost, which includes the fuel and insulation expenses of the pipeline of large diameters that are used to transmit viscous oil.

description: According to the Center for Disease Control children are being diagnosed with autism with greater frequency today than in the past, partially due to the refinement of diagnostic techniques and increased vigilance on the part of parents, pediatricians and teaching professionals. The educational system for those with autism however has not caught up to the growing population. The students are often overlooked by the school district and given classrooms that are detrimental to their sensory perceptions. In order to serve the needs of autistic students, new facilities need to be built and current facilities need to be adapted in order to accommodate this growing population. This thesis imagines a learning environment which both facilitates learning for those with sensory perception issues and creates an environment which fosters social interaction among students regardless of physical and mental capabilities. The design of this learning center will be designed based on research and case studies, followed by  the creation of a set a principles, and the application of  these principles to a test case.

description: We study the ballistic transport in integrable lattice models, i.e., the spin XXZ and Hubbard chains, close to the noninteracting limit. The stiffnesses of spin and charge currents reveal, at high temperatures, a discontinuous reduction (jump) when the interaction is introduced. We show that the jumps are related to the large degeneracy of the parent noninteracting models. These degeneracies are properly captured by the degenerate perturbation calculations which may be performed for large systems. We find that the discontinuities and the quasilocality of the conserved current in this limit can be traced back to the nonlocal character of an effective interaction. From the latter observation we identify a class of observables which show discontinuities in both models. We also argue that the known local conserved quantities are insufficient to explain the stiffnesses in the Hubbard chain in the regime of weak interaction.

description: Urine incontinence and fecal incontinence is a symptom that occurs primarily in women and is often observed in elite athletes. The purpose of the review is to present the pathophysiology of incontinence and pelvic floor rehabilitation. It is important to have proper control and categorization of incontinence. Athletes usually experience incontinence and a weakness of the pelvic floor muscle. Physiotherapy is also included in therapeutic approaches. Research studies have shown that pelvic floor muscle training is a particularly effective form of treatment for incontinence. Further, technques that can be combined with pelvic floor exercises, such as electrical stimulation, pilates or yoga exercises, pharmaceutic treatment or cones appear effective, although there is no experimental justification for their use for each one of them. In conclusion, it appears that incontinence can be treated quite successfully if systematic strengthening and training of pelvic floor muscles is performed for a minimum of 5 months
description: Η ακράτεια ούρων και η ακράτεια κοπράνων είναι ένα σύμπτωμα, που εμφανίζεται κυριώς στις γυναίκες και συχνά συναντάται στις ελίτ αθλήτριες. Σκοπός της ανασκόπησης, είναι η παρουσίαση της παθοφυσιολογίας της ακράτειας και των τεχνικών αποκατάστασης της λειτουργίας των μυών πυελικού εδάφους. Έχει μεγάλη σημασία, να γίνεται σωστός έλεγχος και κατηγοριοποίηση της ακράτειας. Στις αθλήτριες εντοπίζεται συνήθως ακράτεια προσπάθειας, η οποία οδηγεί σε επιβάρυνση του πυελικού εδάφους. Στις θεραπευτικές προσεγγίσεις για την ακράτεια εντάσσεται και η φυσικοθεραπεία. Τα αποτελέσματα των ερευνών δείχνουν, ότι η εκπαίδευση των μυών του πυελικού εδάφους, είναι μια αποτελεσματική μορφή θεραπείας κατά της ακράτειας. Επίσης, τεχνικές που συνδυάζονται με την εκπαίδευση των μυών του πυελικού εδάφους, όπως η βιοανάδραση, το pilates ή yoga, η φαρμακευτική αγωγή, οι κολπικοί κώνοι δείχνουν να είναι αποτελεσματικές. Ωστόσο δεν υπάρχουν πολλές επιστημονικές έρευνες, που να τεκμηριώνουν την αποτελεσματικότητα τους για κάθε μια από αυτές. Φαίνεται ότι η ακράτεια μπορεί να αντιμετωπιστεί θετικά με συστηματική ενδυνάμωση των μυών του πυελικού εδάφους για τουλάχιστον 5 μήνες

description: Background and rationale: Heart failure (HF), which is an emerging public health issue, adversely affects the strained health system in India. The potential adverse impact of HF on the economic well-being of affected individuals and their families is narrated in various anecdotal reports. Further, HF is known to push the affected individuals and their dependents into poverty. However, there is limited research quantifying how HF impacts the economic well-being of households from the low and middle-income countries. Methods: We describe the methods of a detailed economic impact assessment of HF at the household level in India. The economic impact study in HF is initiated across 20 centres in India. The selected centres represent different regions in India stratified based on the prevailing stage of epidemiological transition levels (ETLs). We will collect data from 1800 patients with acute decompensated HF and within 6-15 months of follow-up from the time of initial admission. The data that we intend to collect will consist of a) household healthcare expenditure including out-of-pocket expenditure, b) financing mechanisms used by households and (c) the impoverishing effects of health expenditures including distress financing and catastrophic health expenditure. Trained staff at each centre will collect relevant data by using a validated and structured interview schedule. The study will have 80% power, after accounting for five percent non-response rate, to test eight percent difference in primary outcome (proportion of families under distress financing) between different ETLs. Impact: The results from the study will help policy makers in understanding the micro-economic impact of HF in India and aid in allocation of appropriate resources for prevention and control of HF.

description: The dynamical and topological properties of non-Hermitian systems have attracted great attention in recent years. In this work, we establish an intrinsic connection between two classes of intriguing phenomena -- topological phases and dynamical quantum phase transitions (DQPTs) -- in non-Hermitian systems. Focusing on one-dimensional models with chiral symmetry, we find DQPTs following the quench from a trivial to a non-Hermitian topological phase. Moreover, the number of critical momenta and critical time periods of the DQPTs are found to be directly related to the topological invariants of the non-Hermitian system. We further demonstrate our theory in three prototypical non-Hermitian lattice models, the lossy Kitaev chain (LKC), the LKC with next-nearest-neighbor hoppings, and the nonreciprocal Su-Schrieffer-Heeger model. Finally, we present a proposal to experimentally verify the found connection by a nitrogen-vacancy center in diamond.
