title: Regulation of Stability and Copy Number of Tandem Repeats in Saccharomyces cerevisiae
Creators: name: Salim, Devika
Publisher: name: The Open University
Year: 2020

description: Tandem repeats are inherently unstable and exhibit extensive copy number polymorphisms. Despite mounting evidence for their adaptive potential, the mechanisms associated with regulation of the stability and copy number of tandem repeats remain largely unclear. To study copy number variation at tandem repeats, I used two well-studied repetitive arrays in the budding yeast genome, the ribosomal DNA (rDNA) locus, and the copper-inducible CUP1 gene array. I developed powerful, highly sensitive assays to measure repeat instability and copy number and used them in multiple high-throughput genetic screens to define pathways involved in regulating rDNA copy number variation. These screens revealed that rDNA stability and copy number are regulated by DNA replication, transcription, and histone acetylation. Through parallel studies of the CUP1 array, I showed that instability at both tandem arrays can be induced by DNA replication stress and altered transcription of the locus. Importantly, while changes in instability in response to stress are observed within a few cell divisions, a change in steady state repeat copy number requires selection. Further, H3K56 acetylation is required for regulating transcription and transcription-induced instability at the CUP1 array, and, importantly, it restricts transcription-induced amplification of the CUP1 array. My work suggests that the modulation of replication and transcription is a simple, reversible strategy to alter instability at tandem repeats in response to environmental stimuli, which provides cells rapid adaptability through copy number variation. Additionally, histone acetylation may function to promote the normal adaptive program in response to transcriptional stress. Given the ubiquity of DNA replication, transcription, and chromatin marks like histone acetylation, the mechanisms I have characterized could significantly advance our understanding of the behavior of other tandem repeats and their role in shaping eukaryotic genomes.

description: We investigate the impact of gravity portal to properties of white dwarfs, such as equation-of-state as well as cooling time. We find that the interaction between dark matter spin-zero bosons and electrons in the mean field approximation softens the equation-of-state, and the object coolers down slower compared to the usual case.

description: Pectic oligosaccharides have become novel bioactive components. However, the comprehensive preparation methods, structural features, bioactivities and application of them lack a systematic review. Here, we focused on the enzymatic preparation of pectic oligosaccharides, and attempted to outline relationships among the enzymolysis condition, structure, bioactivities and application of pectic oligosaccharides. Pectic oligosaccharides were characterized by the oligosaccharides with units of →4)-α-GalpA-(1→4)-α-GalpA-(1→ or →4)-α-GalpA-(1→2)-α-Rhap-(1→. Enzymatic method was the most suitable approach for pectic oligosaccharides preparation that was significantly affected by the enzyme’s type, time and concentration. Besides, pectic oligosaccharides possessed various bioactivities including prebiotic, anti-glycosylation, antioxidant, anticancer and lipid metabolism-regulation activities, which were closely associated with the molecular weight, the structure of side chain and the monosaccharide composition. Especially, many pectic oligosaccharides with low molecular weight demonstrated high prebiotic activities, and those with arabinogalactan side chains exhibited strong anticancer activities. Moreover, pectic oligosaccharides have been used in food preservatives, dairy product additives and food processing aids. Nevertheless, the industrial application, novel technology exploration, and structure-bioactivity relationship of pectic oligosaccharides remain a demanding and significant task for future work.

description: The reflection spectrum of a multiple quantum well structure with an inserted defect well is considered. The defect is characterized by the exciton frequency different from that of the host's wells. It is shown that for relatively short structures, the defect produces significant modifications of the reflection spectrum, which can be useful for optoelectronic applications. Inhomogeneous broadening is shown to affect the spectrum in a non-trivial way, which cannot be described by the standard linear dispersion theory. A method of measuring parameters of both homogeneous and inhomogeneous broadenings of the defect well from a single CW reflection spectrum is suggested.

description: Isotopic signatures used in the georeferencing of human remains are largely fixed by spatially distinct geologic and environmental processes. However, location-dependent temporal changes in these isotope ratios should also be considered when determining an individual’s provenance and/or trajectory. Distributions of the relevant isotopes can be impacted by predictable external factors such as climate change, delocalisation of food and water sources and changes in sources and uses of metals. Using Multi-Collector Inductively-Coupled Plasma Mass Spectrometer (MC-ICP-MS) analyses of 206Pb/207Pb in tooth enamel and dentin from a population of 21 ± 1-year-old individuals born circa 1984 and isotope ratio mass spectrometry (IRMS) of δ18O in their enamel, we examined the expected influence of some of these factors. The resulting adjustments to the geographic distribution of isotope ratios (isoscapes) found in tooth enamel and dentin may contain additional useful information for forensic identification, but the shifts in values can also impact the uncertainty and usefulness of identifications if they are not taken into account.KEY POINTSIsoscapes of 206Pb/207Pb and δ18O used for geolocation are not static.Within a few years, the enamel and dentin of a person may exhibit measurable differences in 206Pb/207Pb even without changing locations.Changes in climatic patterns tied to rising temperatures are more significant than the direct effect of increasing temperature on δ18O fixed in tooth bioapatite.Third molar (M3) enamel mineralisation includes material incorporated from before formal amelogenesis takes place.

description: Contrary to the common wisdom, local bosonizations of fermionic systems exist in higher dimensions. Interestingly, resulting bosonic variables must satisfy local constraints of a gauge type. They effectively replace long distance exchange interactions. In this work we study in detail the properties of such a system which was proposed a long time ago. In particular, dependence of the constraints on lattice geometry and fermion multiplicity is further elaborated and is now classified for all two dimensional, rectangular lattices with arbitrary sizes. For few small systems the constraints are solved analytically and the complete spectra of reduced spin hamiltonias are shown to agree with the original fermionic ones. The equivalence is extended to fermions in an external Wegner $Z_2$ field. It is also illustrated by an explicit calculation for a particular configuration of Wegner variables. Finally, a possible connection with the recently proposed web of dualities is discussed.

description: Recently, WMAP has measured the cosmological parameters to a much greater accuracy. We analyze the implications of this more precise measurement for supersymmetric dark matter and for the direct detection of supersymmetry at accelerators. We consider mSUGRA including also the hyperbolic branch in the radiative breaking of the electroweak symmetry. On the part of the hyperbolic branch where the lightest neutralino is dominantly a higgsino rather than being mostly a bino, the relic density constraints are satisfied by coannihilation with the next lightest neutralino and the light chargino. Including this branch the lightest neutralino mass satisfies $m_{χ_1^0}\leq 1200$ GeV for $\tanβ\leq 50$. Constraints of $b\to s+γ$ and of $g_μ-2$ are also analyzed. It is shown that the neutralino-proton cross section in each case will fall within the reach of dark matter experiments. Possibility for the direct detection of supersymmetry is discussed in the allowed regions of the parameter space consistent with WMAP constraints. A brief discussion of the hyperbolic branch and focus point region (HB/FP) is also given.

title: The Influence Of The Material And The Geometry Of Nanoparticles On Their Organ Distribution And Biological Barrier Passage
Creators: name: Talamini, Laura
Publisher: name: The Open University
Year: 2020

description: The interest of nanomaterials for biomedical applications is even more increasing. Several strategies utilising nanoparticles (NPs) to deliver drugs have been widely characterised in these last two decades. In spite of the potential offered by NP-based therapy (e.g. prolonged biodistribution, active target therapy, reduced toxicity, combined diagnosis and therapy), many hurdles hampered the passage from the bench to the bedside. To build up safe and reliable devices, a hierarchical characterisation of the interactions with what NPs will encounter on their way toward the therapeutic target (biological fluids, cells, and organs) is fundamental, even before the loading of the drug. Unfortunately, this aspect is often neglected and the lack of standardised characterisation methods limits the possibility of clearly elucidating the potential of nanomaterials to be used as drug carriers. The aim of my thesis was to investigate how NP physicochemical features such as the material, size, shape and surface functionalization can influence their biodistribution and their passage through biological barriers upon systemic administration in healthy mice. The results of my thesis confirmed a size- and shape- dependent effect of hard NPs to the overall biodistribution. Small spherical gold NPs showed a progressive accumulation over time at variance with larger NPs that accumulated from the beginning in vital organs. On the contrary, Ultrasmall silica NPs preferentially underwent a kidney filtration. They escaped from resident macrophages and therefore did not accumulate in the liver and spleen. Moreover, our findings gave rise doubts about the contribution of the geometry and the functionalization on the passage across the blood-brain barrier after intravenous administration of NPs.

description: Abstract: Corals have evolved as optimized photon augmentation systems, leading to space-efficient microalgal growth and outstanding photosynthetic quantum efficiencies. Light attenuation due to algal self-shading is a key limiting factor for the upscaling of microalgal cultivation. Coral-inspired light management systems could overcome this limitation and facilitate scalable bioenergy and bioproduct generation. Here, we develop 3D printed bionic corals capable of growing microalgae with high spatial cell densities of up to 109 cells mL−1. The hybrid photosynthetic biomaterials are produced with a 3D bioprinting platform which mimics morphological features of living coral tissue and the underlying skeleton with micron resolution, including their optical and mechanical properties. The programmable synthetic microenvironment thus allows for replicating both structural and functional traits of the coral-algal symbiosis. Our work defines a class of bionic materials that is capable of interacting with living organisms and can be exploited for applied coral reef research and photobioreactor design.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

description: The flex-fuel car is a commercial success in Brazil. This innovation illustrates two different strategies of supplier involvement in technology development: black-box and gray-box or co-design. This paper presents two cases studies of how two mature Brazilian automakers subsidiaries (Volkswagen and General Motors) undertook the development of flex-fuel technology. We also present the development’s context, which led to the technology wide spread adoption. Then we discuss the possible impact of both involvement strategies on dependence relations between automakers and their module suppliers, suggesting they will not change large trends toward more, even if limited, dependence on complex high technology modules or “systemist” suppliers.

description: Following our previous work, we continue to explore gravitational dark matter production during the minimal preheating caused by inflaton self-resonance. In this situation there is only one dimensionless index parameter $n$ characterizing the inflation potential after the end of inflation, which leads to a robust prediction on the gravitational dark matter relic abundance. Using lattice method to handle the non-perturbative evolutions of relevant quantities during the inflaton self-resonance, we derive the gravitational dark matter relic abundance arising from both the inflaton condensate and fluctuation annihilation. While being absent for $n=2$, the former one can instead dominate over the later one for $n=4,6$. Our results show that gravitational dark matter mass of $1.04~(2.66)\times 10^{14}$ GeV accommodates the observed value of dark matter relic abundance for $n=4$ (6).

description: We study the spatio-temporal behavior of the Elsässer variables describing magnetic and velocity field fluctuations, using direct numerical simulations of three-dimensional magnetohydrodynamic turbulence. We consider cases with relatively small, intermediate, and large values of a mean background magnetic field, and with null, small, and high cross-helicity (correlations between the velocity and the magnetic field). Wavenumber-dependent time correlation functions are computed for the different simulations. From these correlation functions, the decorrelation time is computed and compared with different theoretical characteristic times: the local non-linear time, the random-sweeping time, and the Alfvénic time. It is found that decorrelation times are dominated by sweeping effects for low values of the mean magnetic field and for low values of the cross-helicity, while for large values of the background field or of the cross-helicity and for wave vectors sufficiently aligned with the guide field, decorrelation times are controlled by Alfvénic effects. Finally, we observe counter-propagation of Alfvénic fluctuations due to reflections produced by inhomogeneities in the total magnetic field. This effect becomes more prominent in flows with large cross-helicity, strongly modifying the propagation of waves in turbulent magnetohydrodynamic flows.

description: Growing demand for the tasty and healthy food has driven the development of low-calorie sweeteners, sweet taste modulators, and bitter masking compounds originated from natural sources. With the discovery of human taste receptors, increasing numbers of sweet taste modulators have been identified through human taste response and molecular docking techniques. However, the discovery of novel taste-active molecules in nature can be accelerated by using advanced spectrometry technologies based on structure-activity relationships (SARs). SARs explain why structurally similar compounds can elicit similar taste qualities. Given the characterization of structural information from reported data, strategies employing SAR techniques to find structurally similar compounds become an innovative approach to expand knowledge of sweeteners. This review aims to summarize the structural patterns of known natural non-nutritive sweeteners, sweet taste enhancers, and bitter masking compounds. Innovative SAR-based approaches to explore sweetener derivatives are also discussed. Most sweet-tasting flavonoids belong to either the flavanonols or the dihydrochalcones and known bitter masking molecules are flavanones. Based on SAR findings that structural similarities are related to the sensory properties, innovative methodologies described in this paper can be applied to screen and discover the derivatives of taste-active compounds or potential taste modulators.

description: We systematically study a collection of refractive phenomena that can possibly occur at the interface of a two-dimensional photonic crystal, with the use of the wave vector diagram formalism. Cases with a single propagating beam (in the positive or the negative direction) as well as cases with birefringence were observed. We examine carefully the conditions to obtain a single propagating beam inside the photonic crystal lattice. Our results indicate, that the presence of multiple reflected beams in the medium of incidence is neither a prerequisite nor does it imply multiple refracted beams. We characterize our results in respect to the origin of the propagating beam and the nature of propagation (left-handed or not). We identified four distinct cases that lead to a negatively refracted beam. Under these findings, the definition of phase velocity in a periodic medium is revisited and its physical interpretation discussed. To determine the ``rightness'' of propagation, we propose a wedge-type experiment. We discuss the intricate details for an appropriate wedge design for different types of cases in triangular and square structures. We extend our theoretical analysis, and examine our conclusions as one moves from the limit of photonic crystals with high index contrast between the constituent dielectrics to photonic crystals with low modulation of the refractive index. Finally, we examine the ``rightness'' of propagation in the one-dimensional multilayer medium, and obtain conditions that are different from those of two-dimensional systems.

In the first chapter (which also forms the first part), which is subdivided into twelve sections, we deal with eleven distinct fuzzy algebraic concepts and in the concluding section list the miscellaneous properties of fuzzy algebra. The eleven fuzzy algebraic concepts which we analyze are fuzzy sets, fuzzy subgroups, fuzzy sub-bigroups, fuzzy rings, fuzzy birings, fuzzy fields, fuzzy semirings, fuzzy near-rings, fuzzy vector spaces, fuzzy semigroups and fuzzy half-groupoids. The results used in these sections are extensive and we have succeeded in presenting new concepts defined by several researchers.

description: Abstract: Vorticity is a key ingredient to a broad variety of fluid phenomena, and its quantised version is considered to be the hallmark of superfluidity. Circulating flows that correspond to vortices of a large topological charge, termed giant vortices, are notoriously difficult to realise and even when externally imprinted, they are unstable, breaking into many vortices of a single charge. In spite of many theoretical proposals on the formation and stabilisation of giant vortices in ultra-cold atomic Bose-Einstein condensates and other superfluid systems, their experimental realisation remains elusive. Polariton condensates stand out from other superfluid systems due to their particularly strong interparticle interactions combined with their non-equilibrium nature, and as such provide an alternative testbed for the study of vortices. Here, we non-resonantly excite an odd number of polariton condensates at the vertices of a regular polygon and we observe the formation of a stable discrete vortex state with a large topological charge as a consequence of antibonding frustration between nearest neighbouring condensates.

The simplest structure that exhibits these effects is the spin ladder with the surface being the ladder end, which can be either compensated or non-compensated spins. The structure with the compensated end has a surface spin flop phase, the non-compensated end has a discommensurational phase, and the transition to these phases can be either first or second order with a tricritical point.

description: No abstracts are to be cited without prior reference to the author.The problem of funding could lead to fewer and less frequent surveys. This study evaluated how such a reduction may affect the quality of Northeast Arctic (NEA) cod stock assessment, which relies on the results of survey data. Based on data from the ICES Arctic Fisheries Working Group collected for the period from 1946 to 2010, VPA/XSA stock assessments were performed in FLR with different assumptions on possible reduction in surveys. For all explored cases of reduced frequency of surveys a serious deterioration of the NEA cod assessment quality was observed. Retrospective patterns of SSB estimates demonstrate possible deviation of up to 55% and the same effect is observed for total stock estimates. If such a situation becomes real, it may lead to serious under/overestimation of the stock and TAC. In addition, in current ICES practice the results of NEA cod assessment are used for NEA haddock assessment and capelin TAC prediction, for which cod consumption is taken into account. Thus a decrease in cod assessment quality will influence the quality of NEA haddock and capelin assessments and advice. It was also concluded that reductions in survey frequency may reduce the quality of assessments for other species as these surveys are multispecies.

description: The Fano and Rabi models represent remarkably common effects in optics. Here we study the coherent time dynamics of plasmonic systems exhibiting Fano and Rabi resonances. We demonstrate that these systems show fundamentally different dynamics. A system with a Fano resonance displays at most one temporal beat under pulsed excitation, whereas a system in the Rabi regime may have any number of beats. Remarkably, the Fano-like systems show time dynamics with very characteristic coherent tails despite the strong decoherence that is intrinsic for such systems. The coherent Fano and Rabi dynamics that we predicted can be observed in plasmonic nanocrystal dimers in time-resolved experiments. Our study demonstrates that such coherent temporal plasmonics includes nontrivial and characteristic relaxation behaviors and presents an interesting direction to develop with further research.

description: No abstracts are to be cited without prior reference to the author.Ecosystem assessment and management in the sea is holistic, based upon interdisciplinary science that considers physical, chemical and biological processes, including feedbacks with human ecological systems, that structure and regulate marine ecosystems. Space and time based tools for the management of human activities in the sea need to be informed by a broad scale habitat ecology that reflects the dynamic realities of the ocean.
title: The Informal Learning of History with Digital Games
Creators: name: Beavers, Sian M
Publisher: name: The Open University

description: Digital games that represent history, i.e. ‘historical games’, are a fundamental way that players can engage with the past. Their focus on historical representations, narratives and processes means educators are using them in formal educational practice. Surprisingly, there is little empirical research on the educational outcomes from the use of historical games in formal contexts, and the specific ways they can increase a learner’s historical awareness and understanding. Existing research on historical game engagements outside of these formal contexts is even scarcer. There has been very little study of whether, what, and how players informally learn through historical games, and their informal learning activities in relation to them. This thesis presents two empirical studies that begin to address this imbalance, exploring player perceptions of historical games as a medium for informal historical learning. The first, an online survey completed by 621 respondents, compared audience and player perceptions of fictive historical film, television series, and games. This situated historical games within the wider media landscape of fictional representations of the past in visual culture, and how they are comparably perceived as media for informal historical learning. The second, more extensive study adopted an ethnographic approach, narrowing the focus of the first by exploring players’ informal learning experiences with historical games that specifically represent classical antiquity. It identified the historical knowledge outcomes particularly associated with historical game use, also examining player’s learning practices with the games that move beyond the game experience (e.g. information seeking, modding, after-action report writing, forum use, and LetsPlay videos). This research thus offers a greater and more comprehensive understanding of informal learning with, and in relation to historical games, highlighting the interplay between these various informal engagements and activities, and how these relationships can influence, determine, or affect player understandings of both the past, and the present.

description: Strategic planning, because of its emphasis on the future, implies extreme subjectivity in the development and assessment of a variety of objectives and strategies. The influence of personal values and priorities of the strategic planning is not limited to personal values and priorities of the company managers, but also other employees and the customers. Personal values and priorities, internal or external, carry with them certain advantages and disadvantages. In some cases they improve strategic planning by creating a differential advantage in the marketplace or in the costs. In contrast, they can sometimes limit the goals and strategies of the company.The company must continuously assess potential trends in personal values and priorities, and on the basis of this assessment to develop variants of the strategic plans of potential changes, taking into account the possible reactions to the same competition. The plan allows the company to better prepare for possible changes in the environment, and the development of strategic variants prepare their business for any events before they actually do occur.
Optimization with nonstationary, nonlinear monolithic fluid-structure interaction

description: Within this work, we consider optimization settings for nonlinear, nonstationary fluid-structure interaction. The problem is formulated in a monolithic fashion using the arbitrary Lagrangian-Eulerian framework to set-up the fluid-structure forward problem. In the optimization approach, either optimal control or parameter estimation problems are treated. In the latter, the stiffness of the solid is estimated from given reference values. In the numerical solution, the optimization problem is solved with a gradient-based solution algorithm. The nonlinear subproblems of the FSI forward problem are solved with a Newton method including line search. Specifically, we will formally provide the backward-in-time running adjoint state used for gradient computations. Our algorithmic developments are demonstrated with some numerical examples as for instance extensions of the well-known fluid-structure benchmark settings and a flapping membrane test in a channel flow with elastic walls.

description: No abstracts are to be cited without prior reference to the author.The crustacean fishery is a highly valuable component of the Portuguese continental bottom trawl fisheries There are about 30 vessels directed to this fishery, operating mainly on the south coast and to a lesser extent on the south-western one, the range of this fishery goes from 150 to more than 600 meters depth. The Crustacean TV Survey is part of the Portuguese contribution to EU Data Collection Framework (DCF), which includes the management and biology of the stocks of crustaceans, Nephrops norvegicus, along with deepwater shrimps such as Parapenaeus longirostris, as the main target species. Among the objectives of the cruise, one stands out as the background of present work: counting of Nephrops galleries from video footages to evaluate the possibility of obtaining a fishery-independent estimation of its density
The stellar disk thickness of LSB galaxies

description: We present surface photometry results for a sample of eleven edge-on galaxies observed with the 6m telescope at the Special Astrophysical Observatory (Russia). The photometric scale length, scale height, and central surface brightness of the stellar disks of our sample galaxies are estimated. We show that four galaxies in our sample, which are visually referred as objects of the lowest surface brightness class in the Revised Flat Galaxies Catalog, have bona fide low surface brightness (LSB) disks. We find from the comparison of photometric scales that the stellar disks of LSB galaxies are thinner than those of high surface brightness (HSB) ones. There is a clear correlation between the central surface brightness of the stellar disk and its vertical to radial scale ratio. The masses of spherical subsystems (dark halo + bulge) and the dark halo masses are obtained for the sample galaxies based on the thickness of their stellar disks. The LSB galaxies tend to harbor more massive spherical subsystems than the HSB objects, whereas no systematic difference in the dark halo masses between LSB and HSB galaxies is found. At the same time, the inferred mass-to-luminosity ratio for the LSB disks appears to be systematically higher than for HSB disks.

KamLAND and Solar Antineutrino Spectrum

description: We use the recent KamLAND observations to predict the solar antineutrino spectrum at some confidence limits. We find that a scaling of the antineutrino probability with respect to the magnetic field profile --in the sense that the same probability function can be reproduced by any profile with a suitable peak field value-- can be utilised to obtain a general shape of the solar antineutrino spectrum. This scaling and the upper bound on the solar antineutrino event rate, that can be derived from the data, lead to: 1) an upper bound on the solar antineutrino flux, 2) the prediction of their energy spectrum, as the normalisation of the spectrum can be obtained from the total number of antineutrino events recorded in the experiment. We get $ϕ_{\barν}<3.8\times 10^{-3}ϕ(^8B)$ or $ϕ_{\barν} <5.5\times 10^{-3}ϕ(^8B)$ at 95% CL, assuming Gaussian or Poissonian statistics, respectively. And for 90% CL these become $ϕ_{\barν}<3.4 \times 10^{-3}ϕ(^8B)$ and $ϕ_{\barν}<4.9\times 10^{-3}ϕ(^8B)$. It shows an improvement by a factor of 3-5 with respect to existing bounds. These limits are quite general and independent of the detailed structure of the magnetic field in the solar interior.

description: In this narrative, I’m looking closer into the light and the world itself, so close that it dissolves into particles. Its particles join the larger ocean of particles. The swirling ocean of particles that represents the world, is the cosmology of this project. In this cosmology, there are no boundaries and no borders, all the entities-including humans and architecture-are interconnected through the currents of this ocean of particles. In such a world, I’m exploring the cycle of time and our perception of it. Time is nothing separate from us, it is simply a part of the same ocean of particles. Time is a product of our consciousness, we construct it as it constructs our consciousness in return. Existence of space is dependent on the presence of time and consciousness. Without which the only thing that is left of space is illusion of space. And eventually, I’m exploring our spatial sense in relation to the journey of time, in other words, the role of architecture and how it changes in relation to the cycle of time; as it drifts apart from the main current at some point and become interwoven again in the flow further in the loop.
