description: Online real estate platforms have become significant marketplaces facilitating users' search for an apartment or a house. Yet it remains challenging to accurately appraise a property's value. Prior works have primarily studied real estate valuation based on hedonic price models that take structured data into account while accompanying unstructured data is typically ignored. In this study, we investigate to what extent an automated visual analysis of apartment floor plans on online real estate platforms can enhance hedonic rent price appraisal. We propose a tailored two-staged deep learning approach to learn price-relevant designs of floor plans from historical price data. Subsequently, we integrate the floor plan predictions into hedonic rent price models that account for both structural and locational characteristics of an apartment. Our empirical analysis based on a unique dataset of 9174 real estate listings suggests that current hedonic models underutilize the available data. We find that (1) the visual design of floor plans has significant explanatory power regarding rent prices - even after controlling for structural and locational apartment characteristics, and (2) harnessing floor plans results in an up to 10.56% lower out-of-sample prediction error. We further find that floor plans yield a particularly high gain in prediction performance for older and smaller apartments. Altogether, our empirical findings contribute to the existing research body by establishing the link between the visual design of floor plans and real estate prices. Moreover, our approach has important implications for online real estate platforms, which can use our findings to enhance user experience in their real estate listings.

Magnetars' Giant Flares: the case of SGR 1806-20
Creators: name: Rea, Nanda

Subjects: subject: Astrophysics (astro-ph)

description: We first review on the peculiar characteristics of the bursting and flaring activity of the Soft Gamma-ray Repeaters and Anomalous X-ray Pulsars. We then report on the properties of the SGR 1806-20's Giant Flare occurred on 2004 December 27th, with particular interest on the pre and post flare intensity/hardness correlated variability. We show that these findings are consistent with the picture of a twisted internal magnetic field which stresses the star solid crust that finally cracks causing the giant flare (and the observed torsional oscillations). This crustal fracturing is accompanied by a simplification of the external magnetic field with a (partial) untwisting of the magnetosphere.

description: Let M be a connected real-analytic hypersurface in N-dimensional complex euclidean space whose Levi form is nondegenerate at some point. We prove that for every point p in M, there exists an integer k=k(M,p) such that germs at p of local real-analytic CR automorphisms of M are uniquely determined by their k-jets (at p). To prove this result we develop a new technique that can be seen as a resolution of the degeneracies of M. This procedure consists of blowing up M near an arbitrary point p in M regardless of its minimality or nonminimality; then, thanks to the blow-up, the original problem can be reduced to an analogous one for a very special class of nonminimal hypersurfaces for which one may use known techniques to prove the finite jet determination property of its CR automorphisms.

description: Searching for Kitaev quantum spin liquid (QSL) is a fascinating and challenging problem. Much effort has been devoted to honeycomb lattice candidates with strong spin-orbit coupling in 5d-electron iridates and 4delectron RuCl3. Recently, theoretical studies suggested that the 3d7 Co-based honeycomb materials with high spin state S=3/2 and effective orbital angular momentum L=1 could also be promising candidates of Kitaev QSL. One of the candidates, BaCo2(AsO4)2, was revisited recently. The long range magnetic order in BaCo2(AsO4)2 can be suppressed by very weak in-plane magnetic field, suggesting its proximity to Kitaev QSL. Here we perform time domain terahertz spectroscopy measurement to study the magnetic excitations on BaCo2(AsO4)2. We observe different magnon excitations upon increasing external magnetic field. In particular, the system is easily driven to a field-polarized paramagnetic phase, after the long range magnetic order is suppressed by a weak field Hc 2. The spectra beyond Hc2 are dominated by single magnon and two magnon excitations without showing signature of QSL. We discuss the similarity and difference of the excitation spectra between BaCo2(AsO4)2 and the widely studied Kitaev QSL candidate RuCl3.

A recital of compositions

Publisher: name: University of British Columbia
Year: 2008

description: Each composition in the following document has resulted from my desire to explore problems and possibilities that are to be found in the various ensembles and/or techniques chosen. For each new composition a particular issue or set of issues was established at the outset and dealt with from different angles at all stages of the works' creation. [1] Chansons Precieux: In these three songs I was interested in reducing my material choices to a minimum and also in creating a small fragment for the text which could be exploded into syllabic utterances. These were, over the course of the three songs, utilized in small groups. Only in the final song is the entire text revealed. [2] Across The Gorge Is The Bridge: Synthesized and concrete sounds constitute the palette of this tape piece. In processing the sounds I selected evolutionary characteristics with the intention of exploiting these characteristics in a particular manner - the notes in the piece are of extremely long duration (c. 12') and so the evolution takes place at a very slow pace. In a sense time is slowed down in the work, almost to the point of absolute stasis. [3] Triangle: Here I examined the concept of an imagined triangular pathway in which each intersection of two lines consisted of the same object viewed in a different way. The lines themselves are manipulations of the object. The original inspiration for this piece came from reading about Stonehenge and other such prehistoric laboratories designed as viewing points for the sun and moon and their risings and settings at key times of the year. [4] Anya Manas: A small item, in this case a chord, is never presented literally, but begins its life in this piece by already having been bent, altered, linearized and otherwise mutilated. Eventually the chord has completely lost its own sense of its own reality. "Anya Manas" is a Sanskrit saying that refers to a state of mind in which confusion of identity prevails. [5] Wo Weilest Du?: This work involved the desire to eliminate such traditional concepts as motivic development, regular phrasing and clear form. Sound objects appear, vanish and may or may not return later. There is no formal goal or climax. The piece simply begins and ends where it does. The title is German and means where are you waiting? It comes from Wagner's Tristan und lsolde.
Threshold between Spontaneous and Cloud-Collisional Star Formation

description: Based on simple physical and geometric assumptions, we have calculated the mean surface molecular density of spiral galaxies at the threshold between star formation induced by cloud-cloud collision and spontaneous gravitational collapse. The calculated threshold is approximately $\log Σ_\mathrm{crit} \sim 2.5$, where $ Σ\quad \mathrm{M_{\solar}}\cdot \mathrm{pc}^{-2}$ is the observed surface mass density of an assumed flat gas disk. Above this limit, the rate of molecular cloud collisions dominates over spontaneous molecular cloud collapse. This model may explain the apparent discontinuity in the Schmidt law found recently at $2 \lesssim \log Σ\lesssim 3$.

Frequency comb generation by Bloch gain induced giant Kerr nonlinearity

description: Optical nonlinearities are known to provide a coherent coupling between the amplitude and phase of the light, which can result in the formation of periodic waveforms. Lasers that emit such waveforms are referred to as optical frequency combs. Here we show that Bloch gain - a nonclassical phenomenon that was first predicted in the 1930s - plays an essential role in comb formation in quantum cascade lasers (QCLs). We develop a self-consistent theoretical model that considers all aspects of comb formation: bandstructure, electron transport, and cavity dynamics. It reveals that Bloch gain gives rise to a giant Kerr nonlinearity and serves as the physical origin of the linewidth enhancement factor in QCLs. Using a master equation approach, we explain how frequency modulated combs can be produced in Fabry-Pérot QCLs over the entire bias range. In ring resonators, Bloch gain triggers phase turbulence and the formation of soliton-like patterns.
Australian medical regulations and strengthened CPD: A policy implementation gap analysis with the specialist medical colleges
Creators: name: Pizzuti, Carol
Publisher: name: F1000 Research Limited
Year: 2024

description: This paper examines the implementation of new mandatory continuing professional development (CPD) requirements for Australian medical practitioners introduced in 2023.

The study focuses on the challenges specialist medical colleges face in meeting these requirements, which include completing specific hours of reviewing performance and measuring outcomes CPD activities using patient health data and large eHealth datasets.

Through a policy implementation gap analysis using semi-structured interviews with staff and CPD Committee members from four participating colleges, the study identifies three key themes: the roles and responsibilities of colleges in the CPD ecosystem, challenges and enablers for policy implementation, and organizational needs and actions required for strengthened CPD.

The findings highlight the need for further research, a reassessment of colleges' roles and responsibilities, and greater collaboration among colleges and data holders to facilitate full policy implementation.

description: We present a first combined analysis of the morphological and dynamical properties for the Intermediate MAss Galaxy Evolution Sequence (IMAGES) sample. It is a representative sample of 52 z~0.6 galaxies with Mstell from 1.5 to 15 10^10Msun and possessing 3D resolved kinematics and HST deep imaging in at least two broad band filters. We aim at evaluate robustly the evolution of rotating spirals since z~0.6, as well as to test the different schemes for classifying galaxies morphologically. We used all the information provided by multi-band images, color maps and 2 dimensional light fitting to assign to each object a morphological class. We divided our sample between spiral disks, peculiar objects, compact objects and mergers. Using our morphological classification scheme, 4/5 of identified spirals are rotating disks and more than 4/5 of identified peculiar galaxies show complex kinematics, while automatic classification methods such as Concentration-Asymmetry and GINI-M20 severely overestimate the fraction of relaxed disk galaxies. Using this methodology, we find that the fraction of rotating spirals has increased by a factor ~ 2 during the last 6 Gyrs, a much higher fraction that found previously based on morphologies alone. These rotating spiral disks are forming stars very rapidly, doubling their stellar masses over the last 6 Gyrs, while most of their stars have been formed few Gyrs earlier, which reveals the presence of a large gas supply. Because they are likely the progenitors of local spirals, we can conjecture how their properties are evolving. Their disks show some evidence for an inside-out growth and the gas supply/accretion is not made randomly as the disk need to be stable in order to match the local disk properties.

DETECTIFz galaxy groups in the REFINE survey -- 1. Group detection and quenched fraction evolution at $z < 2.5$

description: We use a large K-selected sample of 299,961 galaxies from the REFINE survey, consisting of a combination of data from three of the deepest near-infrared surveys: UKIDSS UDS, COSMOS/UltraVISTA and CFHTLS-D1/VIDEO, that were homogeneously reduced to obtain photometric redshifts and stellar masses. We detect 2588 candidate galaxy groups up to $z=3.15$ at $S/N>1.5$. We build a very pure ($>90\%$) sample of 448 candidate groups up to $z=2.5$ and study some of their properties. Cluster detection is done using the DElaunay TEssellation ClusTer IdentiFication with photo-z (DETECTIFz) algorithm that we describe. This new group finder algorithm uses the joint probability distribution functions (PDF) of redshift and stellar-mass of galaxies to detect groups as stellar-mass overdensities in overlapping redshift slices, where density is traced using Monte Carlo realisation of the Delaunay Tessellation Field Estimator (DTFE). We compute the algorithm selection function using mock galaxy catalogues taken from cosmological N-body simulation lightcones. Based on these simulations, we reach a completeness of $\sim80\%$ for clusters ($M_{200}>10^{14} M_{\odot}$) at a purity of $\sim90\%$ at $z<2.5$. Using our 403 most massive candidate groups, we constrain the redshift evolution of the group galaxy quenched fraction at $0.12\le z<2.32$, for galaxies with $10.25 < \log M_\star/M_{\odot} < 11$ in $0.5\times R_{200}$. We find that the quenched fraction in group cores is higher than in the field in the full redshift range considered, the difference growing with decreasing redshift. This indicates either more efficient quenching mechanisms in group cores at lower redshift or pre-processing by cosmic filaments.

description: We give an explicit characterization of the most general quasi-Hermitian operator H, the associated metric operators η_+, and η_+-pseudo-Hermitian operators acting in two-dimensional complex Euclidean space C^2. These operators represent the physical observables of a model whose Hamiltonian and Hilbert space are respectively H and C^2 endowed with the inner product defined by η_+. Our calculations allows for a direct demonstration of the fact that the choice of an irreducible family of observables fixes the metric operator up to a multiplicative factor.

description: As an application in circuit quantum electrodynamics (cQED) coupled systems, superconducting resonators play an important role in high-sensitivity measurements in a superconductingsemiconductor hybrid architecture. Taking advantage of a high-impedance NbTiN resonator, we perform excited-state spectroscopy on a GaAs double quantum dot (DQD) by applying voltage pulses to one gate electrode. The pulse train modulates the DQD energy detuning and gives rise to charge state transitions at zero detuning. Benefiting from the outstanding sensitivity of the resonator, we distinguish different spin-state transitions in the energy spectrum according to the Pauli exclusion principle. Furthermore, we experimentally study how the interdot tunneling rate modifies the resonator response. The experimental results are consistent with the simulated spectra based on our model.

description: It has been shown that the criticism of Pauli as well as of Susskind and Glogover may be avoided if the standard quantum-mechanical mathematical model has been suitably extended. There is not more any reason for Einstein's citicism, either, if in addition to some new results concerning Bell's inequalities and Belifante's argument are taken into account. The ensemble interpretation of quantum mechanics (or the hidden-variable theory) should be preferred, which is also supported by the already published results of experiments with three polarizers. Greater space in the text has been devoted also to the discussion of epistemological problems and some philosophical consequences.

In this paper, we first determine the maximum Sombor index among cacti with $n$ vertices and $t$ cycles, then determine the maximum Sombor index among cacti with perfect matchings.

The idea of the “Semantic Web” was suggested as a solution that would create a structure able to host this information based on the technology of ontologies. Ontologies are structured knowledge representation systems, like graphs, that can contain the knowledge existing in data and create new information based on it. In this study, the process of creating a system like that will be presented by following a process with certain steps. In order to present this process properly, an ontology will be created based on the domain of dragons in ancient Greek mythology, and some of the functionalities and features of the knowledge graphs will be explained in order to prove the significance of this technology.

description: We provide a "first principles" description of scattering from open quantum systems subject to a Lindblad-type dynamics. In particular we consider the case that the duration of the scattering process is of similar order as the decoherence time of the scatterer. Under rather general conditions, the derivations lead to the the following new result: The irreversible time-evolution may cause a reduction of the system's transition rate being effectuated by scattering. This is tantamount to a shortfall of scattering intensity. The possible connection with striking experimental results of neutron and electron Compton scattering from protons in condensed matter is mentioned.

description: The study was conducted to achieve the main objective of mango Value chain in the study area. About 52 respondents of mango value chain actors were selected randomly from four keeled administration of Simada woreda. The study employed both qualitative and quantitative type of data. Primary data were collected by close ended and open Questionnaires, personal interview; focus group discussion and key informant interview and the secondary data were taken from different written. The collected data were analyzed by using stasticial tools like mean, standard devation, frequency, tables and percentage methods. The study has indicated that direct actors along mango value chain include producers, wholesalers, retailers and consumers and also indirect actors such as extension service providers, credit and saving service. From the research I summarize 72.7% of mango was produced by males and some of the respondents were females (27.3%). In the study area household heads more tend to be males and also most of the practicing in production of mango was by males. From this I recommend female should participate in mango production and the government and other concerned body should play a great roll in order to improve quality of mango production, input supply and income in the study area.

description: We study three-dimensional time-reversal-invariant topological superconductivity in noncentrosymmetric materials such as RhSi, CoSi, and AlPt which host coupled multifold nodes energetically split by the spin-orbit coupling at the same time-reversal-invariant momentum (TRIM). The topological superconductivity arises from the $s_{+} \oplus s_{-}$ gap function, which is $\boldsymbol{k}$ independent, but with opposite signs for the two nodes split at the same TRIM. We consider various electron-electron interactions in the tight-binding model for RhSi and find that the topological superconducting phase supporting a surface Majorana cone and topological nodal rings is favored in a wide range of interaction parameters.

description: There is broad agreement that language change can result from external factors (contact-induced change), or internal factors, but there is no consensus on what constrains these types of changes, nor on the interaction between them. This talk addresses these questions by examining several salient grammatical constructions in Rangi, a Bantu language which has been in sustained contact with non-Bantu languages. Exploring the various pieces of evidence for the sources of these constructions (some of which point to external factors, and others which point to internal factors), is a practical exercise in dealing with the complexity of accounting for processes of change.

There are now four detached eclipsing binaries which are likely members of the cluster. Determination of the absolute parameters of the components would provide a valuable check on evolutionary models of low-mass stars. An accurate ephemeris and orbital period analysis are presented for the previously-known detached binary NV CMa. We also provide ephemerides for 7 other periodic variables. We show that 3 contact binaries are likely members of the cluster.

New chiral fermions charged under the extended gauge symmetry have nonzero lepton numbers, which makes the $B-L$ symmetry anomalous. The new lepton sector contains a large flavor-dependent CP violation, similar to the Cabibbo-Kobayashi-Maskawa phase, without inducing sizable electric dipole moments of the Standard Model particles. A bubble wall dynamics associated with the first-order phase transition and $SU(2)_R$ sphaleron processes generate a lepton asymmetry, which is transferred into a baryon asymmetry via the ordinary electroweak sphaleron process. Unlike the Standard Model electroweak baryogenesis, the new phase transition can be of the strong first order and the new CP violation is not significantly suppressed by Yukawa couplings, so that the observed asymmetry can be produced. The model can be probed by collider searches for new particles and the observation of gravitational waves. One of the new leptons becomes a dark matter candidate. The model can be also embedded into a left-right symmetric theory to solve the strong CP problem.

description: Σκοπός της μεταπτυχιακής διατριβής ήταν να συγκρίνει την αποτελεσματικότητα 2 διαφορετικών πρωτοκόλλων ενεργητικής προθέρμανσης εκτός νερού στην κολυμβητική επίδοση σε μέγιστη προσπάθεια 50 m, σε κινηματικές παραμέτρους (μήκος, συχνότητα και δείκτης χεριάς), στην υποκειμενική αντίληψη της κόπωσης και στην καρδιακή συχνότητα σε αθλητές και των 2 φύλων. Οι άνδρες και οι γυναίκες αθλητές κολύμβησης αντιδρούν διαφορετικά μετά από πρωτόκολλα μυϊκής ενεργοποίησης εκτός νερού και δυναμικών διατάσεων. Η διαφοροποίηση της επίδρασης των πρωτοκόλλων στους συμμετέχοντες, καθιστά σημαντική τη σημασία της εξατομίκευσης των πρωτοκόλλων προθέρμανσης εκτός νερού που εφαρμόζονται με στόχο τη μεγιστοποίηση της κολυμβητικής απόδοσης στην απόσταση των 50 m εκτελούμενων με την «ελεύθερη» τεχνική.
description: The purpose of this thesis was to compare the effectiveness of 2 different dry-land active warm-up protocols on 50-m front-crawl swimming performance, biomechanical variables (stroke rate, stroke length, and stroke index), rate of perceived exertion, and exercise heart rate in swimmers of both genders. Male and female swimmers respond differently to a power or a dynamic stretching protocol. The variation in responses to different warm-up conditions highlights the importance of individualizing the dry-land warm-up procedure to promote maximum performance during 50-m front-crawl swimming.

description: We present a simple model for the formation of pairs in multi-agent populations of type A and B which move freely on a spatial network. Each agent of population A (and B) is labeled as Ai (and Bj) with i=1,.. NA (and j=1,..NB) and carries its own individual list of characteristics or 'phenotype'. When agents from opposite populations encounter one another on the network, they can form a relationship if not already engaged in one. The length of time for which any given pair stays together depends on the compatibility of the two constituent agents. Possible applications include the human dating scenario, and the commercial domain where two types of businesses A and B have members of each type looking for a business partner, i.e. Ai+Bj-->Rij. The pair Rij then survives for some finite time before dissociating Rij-->Ai+Bj. There are many possible generalizations of this basic setup. Here we content ourselves with some initial numerical results for the simplest of network topologies, together with some accompanying analytic analysis.

description: In multi-view fluorescence microscopy, each angular acquisition needs to be aligned with care to obtain an optimal volumetric reconstruction. Here, instead, we propose a neat protocol based on auto-correlation inversion, that leads directly to the formation of inherently aligned tomographies. Our method generates sharp reconstructions, with the same accuracy reachable after sub-pixel alignment but with improved point-spread-function. The procedure can be performed simultaneously with deconvolution further increasing the reconstruction resolution.

description: We present the results of a high sensitivity survey for 6.7 GHz methanol masers towards 22 GHz water maser using the 100 m Efflesberg telescope. A total of 89 sources were observed and 10 new methanol masers were detected. The new detections are relatively faint with peak flux densities between 0.5 and 4.0 Jy. A nil detection rate from low-mass star forming regions enhances the conclusion that the masers are only associated with massive star formation. Even the faintest methanol maser in our survey, with a luminosity of 1.1 $10^{-9} L_\odot$ is associated with massive stars as inferred from its infrared luminosity.

description: The dynamics of vibrational wave packets excited in K$_2$ dimers attached to superfluid helium nanodroplets is investigated by means of femtosecond pump-probe spectroscopy. The employed resonant three-photon-ionization scheme is studied in a wide wavelength range and different pathways leading to K$^+_2$-formation are identified. While the wave packet dynamics of the electronic ground state is not influenced by the helium environment, perturbations of the electronically excited states are observed. The latter reveal a strong time dependence on the timescale 3-8 ps which directly reflects the dynamics of desorption of K$_2$ off the helium droplets.

To get good student ratings should you only teach programming courses? Investigation and implications of student evaluations of teaching in a software engineering context

description: Student evaluations of teaching (SET) are commonly used in universities for assessing teaching quality. However, previous literature shows that in software engineering students tend to rate certain topics higher than others: In particular students tend to value programming and software construction over software design, software engineering models and methods, or soft skills. We hypothesize that these biases also play a role in SET responses collected from students. The objective of this study is to investigate how the topic of a software engineering course affects the SET metrics. We accomplish this by performing multilevel regression analysis on SET data collected in a software engineering programme. We analyzed a total of 1295 student evaluations from 46 university courses in a Finnish university. The results of the analysis verifies that the student course evaluations exhibit similar biases as distinguished by previous software engineering education research. The type of the course can predict a higher SET rating. In our dataset, software construction and programming courses received higher SET ratings compared to courses on software engineering processes, models, and methods.

Multifilter spectrophotometry of the environment of the quasar 3C281
Creators: name: Craven, Sally Eve
Publisher: name: University of British Columbia
Year: 2008

description: The technique of multifilter spectrophotometry is applied to identify stars and deduce galaxy redshifts and morphological types in a field centred on the quasar 3C281, with the intention of both testing the method and identifying members of the galaxy cluster surrounding the QSO. Photometry is performed on CCD images taken in twenty-four narrowband filters, and the resulting spectral energy distributions are compared with redshifted model galaxy spectra from Rocca-Volmerange and Guiderdoni (1988) and with fiducial star spectra from Gunn and Stryker (1983) to determine the physical characteristics of the best-fitting spectral template. For twelve of the 184 objects in the 3.7'x6' field, spectroscopic redshifts have been published (Ellingson, Green, and Yee 1991), and an attempt is made to examine the accuracy of the technique using this small sample: a relationship between object signal-to-noise ratio and error in assigned redshift is sought. The results of a complementary study using simulated spectral energy distributions (Callaghan, Gibson, and Hickson 1992; Callaghan 1992) are briefly described, and compared with results from this data set. A broadband R filter is simulated by combining twenty-one narrowband filters, and the instrumental magnitudes are calibrated with published magnitudes from Yee, Green, and Stockman (1986). The photometric errors are found to increase substantially with decreasing signal-to-noise ratio, but the results suggest that broadband multicolour photometry could be fairly accurately performed for many of the objects in the field, if the appropriate narrowband filters were present. Of the commonly used broadband filters UBVRI, this data set has spectral coverage adequate to simulate only the R filter. Multifilter spectrophotometry has the potential to be a versatile and efficient survey technique, and will be employed in the sky survey to be made in forty filters by the UBC Liquid Mirror Telescope (Hickson et al. 1993, Gibson & Hickson 1991).
Horizon thermalization of Kerr black hole through local instability

description: The validity of our already proposed conjecture -- {\it horizon creates a local instability which acts as the source of the quantum temperature of black hole} -- is being tested here for Kerr black hole. Earlier this has been explicitly shown for spherically symmetric static black hole (SSS BH). The more realistic situation like Kerr spacetime, being stationary and axisymmetric, is a non-trivial example to analyze. We show that for a chargeless massless particle, the near horizon radial motion in Kerr spacetime, like SSS BH, can be locally unstable. The radial contribution in the corresponding Hamiltonian is $\sim xp$ kind, where $p$ is the canonical momentum and $x$ is its conjugate position of particle. Finally we show that the horizon thermalization can be explained through this Hamiltonian when one dose a semi-classical analysis. It again confirms that near horizon instability is liable for its own temperature and moreover generalizes the validity of our conjectured mechanism for the black hole horizon thermalization.

description: The complexity of the cells can be described and understood by a number of networks such as protein-protein interaction, cytoskeletal, organelle, signalling, gene transcription and metabolic networks. All these networks are highly dynamic producing continuous rearrangements in their links, hubs, network-skeleton and modules. Here we describe the adaptation of cellular networks after various forms of stress causing perturbations, congestions and network damage. Chronic stress decreases link-density, decouples or even quarantines modules, and induces an increased competition between network hubs and bridges. Extremely long or strong stress may induce a topological phase transition in the respective cellular networks, which switches the cell to a completely different mode of cellular function. We summarize our initial knowledge on network restoration after stress including the role of molecular chaperones in this process. Finally, we discuss the implications of stress-induced network rearrangements in diseases and ageing, and propose therapeutic approaches both to increase the robustness and help the repair of cellular networks.

description: We consider the classical algebra of observables that are diagonal in a given orthonormal basis, and define a complete decoherence process as a completely positive map that asymptotically converts any quantum observable into a diagonal one, while preserving the elements of the classical algebra. For quantum systems in dimension two and three any decoherence process can be undone by collecting classical information from the environment and using such an information to restore the initial system state. As a relevant example, we illustrate the quantum eraser of Scully et al. [Nature 351, 111 (1991)] as an example of environment-assisted correction. Moreover, we present the generalization of the eraser setup for d-dimensional systems, showing that any von Neumann measurement on a system can be undone by a complementary measurement on the environment.
