description: A cadeia de frango de corte no Paraná se consolidou, principalmente, no interior do Estado, onde concentra 79% da produção. Esta atividade contribui significativamente para a geração de superávits na balança comercial. O objetivo deste artigo foi discutir a distribuição da quase-renda na cadeia de frango de corte paranaense por meio da análise do custo de transação visando avaliar o incentivo dos produtores e abatedouros a permanecer na atividade. A produção avícola no estado é realizada por duas estruturas de governança distintas - firmas integradoras ou cooperativas. Acredita-se que cada uma delas estabelece diferentes padrões de apropriação dos resultados. Verificou-se que as diferentes estruturas de governança refletem particularidades nas transações, sejam referentes à característica própria do tipo de organização (cooperativa ou não), à capacidade de inovação (inovadora ou imitadora) ou ao direcionamento de mercado (apenas interno ou interno e externo). As particularidades da transação e a vinculação da mesma com as demais etapas da cadeia permitem a existência, no longo prazo, da quase-renda em uma disputa conflituosa entre o oportunismo, por parte dos abatedouros, e da permanência na atividade, por parte dos produtores.

description: We use Monte Carlo simulations to identify the mechanism that allows for phase transitions in dipolar spin ice to occur and survive for applied magnetic field, H, much larger in strength than that of the spin-spin interactions. In the most generic and highest symmetry case, the spins on one out of four sublattices of the pyrochlore decouple from the total local exchange+dipolar+applied field. In the special case where H is aligned perfectly along the [110] crystallographic direction, spin chains perpendicular to H show a transition to q=X long range order, which proceeds via a one to three dimensional crossover. We propose that these transitions are relevant to the origin of specific heat features observed in powder samples of the Dy2Ti2O7 spin ice material for H above 1 Tesla.

description: The paper proposes a synchropahsor estimation (SE) algorithm that leverages the use of a delayed in-quadrature complex signal to mitigate the self-interference of the fundamental tone. The estimator, which uses a three-point IpDFT combined with a three-cycle Hanning window, incorporates a new detection mechanism to iteratively estimate and remove the effects caused by interfering tones within the out-of-band interference (OOBI) range. The main feature of the method is its ability to detect interfering tones with an amplitude lower than that adopted by the IEC/IEEE Std. 60255-118, this detection being notably challenging. Furthermore, it simultaneously satisfies all the accuracy requirements for the P and M phasor measurement unit (PMU) performance classes, while offering a reduction in the total computational cost compared to other state-of-the-art techniques. Despite an increase in total memory requirements, a preliminary analysis reveals its suitability for implementation on embedded devices.

description: O Ceará, estado situado na área do polígono das secas, tem sua história marcada pela difícil condição climática à qual grande parte da sua população rural está submetida e pelas estratégias de sobrevivência desenvolvidas por esta para resistir aos impactos causados pelas variações climáticas, principalmente no sertão semi-árido. Apresenta-se nesta pesquisa uma proposta de investigação sobre emigração, destacando a importância do estudo da afetividade para a compreensão das relações sociais, tendo como objetivo investigar os afetos que marcam a relação de jovens do sertão semi-árido nordestino com seu entorno e com sua decisão entre emigrar ou não, através do estudo da afetividade, que pode nos mostrar, segundo Sawaia (1999), uma nova forma de compreensão da desigualdade e da dialética inclusão/exclusão social. A pesquisa foi realizada em três escolas públicas localizadas na sede do município de Tauá-CE. A amostra dos sujeitos se constituiu de jovens que estivessem cursando o último ano do ensino médio, fossem maiores de 18 anos, devendo também ser composta de moradores tanto da sede como das comunidades rurais do município e de ambos os sexos. Para a apreensão dos afetos, foi utilizada o método dos mapas afetivos (Bomfim,2003). A análise dos dados foi feita de forma qualitativa através da análise de conteúdo e contou com uma análise estatística complementar. Observou-se que a decisão de emigrar sofre a influência de fatores bastante subjetivos, sendo a relação afetiva com a cidade importante nessa decisão, pois as pessoas que apresentam uma estima mais negativa em relação à sua comunidade estão mais propensas à emigração. Entre os grupos, notou-se que as mulheres e os jovens maiores de 21 anos têm maior tendência à migração. A importância do estudo se deve ao fato de que, através da compreensão de como a juventude é afetada emocionalmente pelas contingências sociais, pode-se inferir sobre as ações éticas desses jovens, ações estas que ocasionam a manutenção da realidade existente ou a transformação da mesma.

description: This paper presents a quantum mechanical treatment for both atomic and field fluctuations of an atomic ensemble interacting with propagating fields, either in Electromagnetically Induced Transparency or in a Raman situation. The atomic spin noise spectra and the outgoing field spectra are calculated in both situations. For suitable parameters both EIT and Raman schemes efficiently preserve the quantum state of the incident probe field in the transfer process with the atoms, although a single pass scheme is shown to be intrinsically less efficient than a cavity scheme.

description: O presente texto discute as possibilidades da organização de redes de unidades produtivas como instrumento de apoio ao desenvolvimento territorial rural (DTR), tomando como objeto de análise empírica o projeto Redes de Referências para a Agricultura Familiar, conduzido no Estado do Paraná, Brasil, sob responsabilidade do Instituto Agronômico do Paraná (IAPAR) e Empresa Paranaense de Assistência Técnica e Extensão Rural (EMATER/PR). Partindo do referencial teórico analisado e de informações coletadas junto a especialistas envolvidos com o tema, o trabalho discute a pertinência da organização de redes em ações de DTR, bem como os ajustes necessários no atual projeto para a sua adoção nessa perspectiva. Considerando aspectos relativos à formação de capital social, à valorização de atributos para a construção de territórios e ao incentivo do desenvolvimento endógeno, a pesquisa aponta a adoção da estratégia de redes de unidades produtivas como instrumento adequado às ações de DTR. Constata também que as perspectivas da inovação tecnológica e gerencial; de aumento da competitividade territorial; de aprimoramento institucional associado à transformação dos sistemas produtivos; e a possibilidade de validação e transferência de inovações surgidas no meio rural, todos elementos presentes no projeto Redes de Referências para a Agricultura Familiar, qualificam-no como potencialmente útil às ações desenvolvidas sob o enfoque do DTR. O texto aborda ainda as perspectivas futuras para o projeto Redes de Referências, considerando sobretudo os aspectos necessários para a sua adequação ao enfoque do desenvolvimento sob a ótica territorial. Tais aspectos são discutidos considerando o escopo atual do projeto, as mudanças de ordem metodológica e/ou operacional pertinentes e, ainda, os ajustes necessários no plano institucional para a sua implementação, oferecendo assim, elementos que devem permitir uma melhor adequação da proposta às ações de DTR.

description: It is a safe conjecture that most (not necessarily periodic) two-dimensional Lorentz gases with finite horizon are recurrent. Here we formalize this conjecture by means of a stochastic ensemble of Lorentz gases, in which i.i.d. random scatterers are placed in each cell of a co-compact lattice in the plane. We prove that the typical Lorentz gas, in the sense of Baire, is recurrent, and give results in the direction of showing that recurrence is an almost sure property (including a zero-one law that holds in every dimension). A few toy models illustrate the extent of these results.

description: We report results of experiments with liquid $^3$He confined in a high porosity anisotropic nanostructure which we call planar aerogel. This aerogel consists of nanofibers (with diameters $\sim10$ nm) which are randomly oriented in the plane normal to the specific axis. We used two samples of planar aerogel prepared using different techniques. We have found that on cooling from the normal phase of $^3$He the superfluid transition in both samples occurs into an equal spin pairing superfluid phase. NMR properties of this phase qualitatively agree with the properties of the superfluid A phase in the anisotropic Larkin-Imry-Ma state. We have observed differences between results obtained in the presence and absence of solid paramagnetic $^3$He on the aerogel strands. We propose that these differences may be due, at least in part, to a magnetic scattering channel which appears in the presence of solid paramagnetic $^3$He.

description: I present light curves for two detached eclipsing binary stars in the region of the LMC cluster NGC 1850, which is possibly a young globular cluster still in formation. One, a likely spectral type O star, is a newly detected eclipsing binary in the region of the very young subcluster NGC 1850A. This binary is among a small number of highly massive O-type stars in binary systems found in LMC clusters. These two eclipsing binaries are the first discovered in the well studied NGC 1850, and the O-type star is the first eclisping binary found in NGC 1850A. Light curves for two NGC 1850 region Cepheid variables are also shown. Discovering two eclipsing binaries in the young globlular-like cluster NGC 1850 is discussed in terms of the importance of the binary fraction to globular cluster evolution.

On the Local Donaldson-Thomas theory of curves
Creators: name: Song, Yinan
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis, we study the Donaldson-Thomas theory of local curves. The motivation is the Gromov-Witten/Donaldson-Thomas correspondence. First, we review the gauge theory motivation of the original construction and the history of the Donaldson-Thomas theory. Then we review the construction of Gieseker-Maruyama-Simpson moduli spaces and their relation with Hilbert schemes of threefolds. We also review the concept of a perfect obstruction theory and its relation with the virtual fundamental classes. Then we describe the Gromov-Witten/Donaldson-Thomas correspondence and the equivariant generalization. We study the equivariant Donaldson-Thomas theory of two types of threefolds. First, we consider the total space of P²-bundles over smooth curves of genus g with (C*)³ action along the fiber, and we consider the curve class of a section plus the class of a line in the fiber. We compute the Donaldson-Thomas partition function up to the first order and we find that it agrees with the Gromov-Witten prediction. The second case we consider is the local curve case. The threefold is the total space of a direct sum of two line bundles of opposite degree with an anti-diagonal action along the fiber. Based on the calculation from Gromov-Witten theory, the only non-trivial contributions to the Donaldson-Thomas partition function come from components that parametrize subschemes of pure dimension. We compute these contributions and find that they agree with the Gromov-Witten prediction. We are also able to verify the vanishing of contributions from the so-called product-type components.

description: Overcoming the influence of noise and imperfections is a major challenge in quantum computing. Here, we present an approach based on applying a desired unitary computation in superposition between the system of interest and some auxiliary states. We demonstrate, numerically and on the IBM Quantum Platform, that parallel applications of the same operation lead to significant noise mitigation when arbitrary noise processes are considered. We first design probabilistic implementations of our scheme that are plug and play, independent of the noise characteristic and require no postprocessing. We then enhance the success probability (up to deterministic) using adaptive corrections. We provide an analysis of our protocol performance and demonstrate that unit fidelity can be achieved asymptotically. Our approaches are suitable to both standard gate-based and measurement-based computational models.

title: A Critical Analysis Of Actions Taken Upon Historic Musical Instruments Through The Period Of The Early Music Revival From The Beginning Of The 20th Century To The 1990s
Creators: name: Barclay, Robert Leslie
Publisher: name: The Open University
Year: 1999

description: This work is a critical analysis of craft internvention upon historic musical instruments. It is centred upon the tension between use and preservation that arose with the conflicting demands of the early music revival for working musical instruments,and of the conservation discipline for the preservation of these artefacts as documents of contemporary instrument-making and musical practices. A framework is developed around three regimens of function, termed Currency, Restitution and Preservation, within which the actions and rationales of craft activity on musical instruments may be characterized. Case studies of nine historic instruments are presented in order to demonstrate the derivation of both the technical and social factors that contributed to their changes in state and status during the period under study. Analysis of the actions taken upon the instruments in their historical and social contexts provides a novel understanding of the relationship between the desire for musical experience, and the need for historical and technical information. The work concludes with a discussion of a strategy for encouraging a balance between musical function and preservation, thus mediating between the conflicting demands.

description: The COVID-19 pandemic has greatly increased remote work among enterprise employees. Home-network environments are not professionally managed, so they are an appealing target for attackers. These attackers are aware that systems on home networks are not patched regularly and a number of them are out of date with respect to vulnerability mitigation. Threat detection is typically nearly absent on home systems, and remediation is often incidental at best.

description: We develop the pseudo-Cl method for reconstructing the Cosmic Microwave Background (CMB) temperature and polarization auto- and cross-power spectra, and estimate the pseudo-Cl covariance matrix for a realistic experiment on the cut sky. We calculate the full coupling equations for all six possible CMB power spectra, relating the observed pseudo-Cl's to the underlying all-sky Cl's, and test the reconstruction on both full-sky and cut-sky simulated CMB data sets. In particular we consider the reconstruction of the Cl from upcoming ground-based polarization experiments covering areas of a few hundred sq. degrees and find that the method is fast, unbiased and performs well over a wide range of multipoles from l=2 to l=2500. We then calculate the full covariance matrix between the modes of the pseudo-temperature and polarization power spectra, assuming that the underlying CMB fields are Gaussian randomly distributed. The complexity of the covariance matrix prohibits its rapid calculation, required for parameter estimation. Hence we present an approximation for the covariance matrix in terms of convolutions of the underlying power spectra. The coupling matrices in these expressions can be estimated by fitting to numerical simulations, circumventing direct and slow calculation, and further, inaccurate analytic approximations. We show that these coupling matrices are mostly independent of cosmology, and that the full covariance matrix for all six pseudo-Cl power spectra can be quickly and accurately calculated for any given cosmological model using this method. We compare these semi-analytic covariance matrices against simulations and find good agreement, the accuracy of which depends mainly on survey area and the range of cosmological parameters considered.

description: This paper shows first quantitative analysis of the detachment processes in the MAST Upgrade Super-X divertor (SXD). We identify an unprecedented impact of plasma-molecular interactions involving molecular ions (likely $D_2^+$), resulting in strong ion sinks (Molecular Activated Recombination - MAR), leading to a reduction of ion target flux. The MAR ion sinks exceed the divertor ion sources before electron-ion recombination (EIR) starts to occur, suggesting that significant ionisation occurs outside of the divertor chamber. In the EIR region, $T_e \ll 0.2$ eV is observed and MAR remains significant in these deep detached phases. The total ion sink strength demonstrates the capability for particle (ion) exhaust in the Super-X Configuration.
 Molecular Activated Dissociation (MAD) is the dominant volumetric neutral atom creation process can lead to an electron cooling of 20\% of $P_{SOL}$. The measured total radiative power losses \emph{in the divertor chamber} are consistent with inferred hydrogenic radiative power losses. This suggests that intrinsic divertor impurity radiation, despite the carbon walls, is minor in the divertor chamber. This contrasts previous TCV results, which may be associated with enhanced plasma-neutral interactions and reduced chemical erosion in the detached, tightly baffled SXD.
 The above observations have also been observed in higher heat flux (narrower SOL width) type I ELMy H-mode discharges. This provides evidence that the characterisation in this paper may be general.

description: Inflammation-related pathologies remain a serious health problem with high costs for the community. Citrus flavonoids are known to possess important pharmacological properties, including anti-inflammatory activity. In this study we evaluated the effects of a flavonoid-rich extract of orange juice (OJe) in an experimental model of enteritis induced by Vibrio anguillarum in adult zebrafish (Danio rerio). Administration of V. anguillarum through live feed (Artemia nauplii) for three consecutive days caused evident signs of enteritis in zebrafish. Three days of treatment with OJe before the pathogenic insult resulted in a remarkable reduction of tissue inflammatory events as well as a molecular down-regulation of the inflammatory genes such as IL-1β, IL-6 and TNFα. Our data suggest that OJe counteracts the inflammation of zebrafish intestinal mucosa, indicating that the pool of flavonoids present in orange juice could be useful for the prevention of enteritis.

description: O Município de Bonito, situado na Região Sudeste do Estado de Mato Grosso do Sul, até a década de oitenta teve na agricultura sua principal base econômica, porém com a crise gerada no setor, a pecuária foi substituindo aos poucos esta atividade. O Município situado na Serra da Bodoquena, lugar privilegiado com belíssimas paisagens e uma grande diversidade de flora e fauna terrestre, além de diversos rios e cachoeiras, essas características fizeram com que a partir nos anos 1990 houvesse o desenvolvimento do turismo na região, incrementando desta forma o setor de serviços. Assim o estudo teve como objetivo verificar a concentração da agropecuária e do setor de serviços no Município de Bonito. De maneira a constatar que a atividade agropecuária tem se sobressaído como atividade de maior contribuição no período de 1999 a 2003.
title: The metamorphosis of Battersea, 1800-1914: a building history
Creators: name: Bailey, Keith Alan
Publisher: name: The Open University
Year: 1995

description: The Metamorphosis of Battersea is a study of the process of building development in a London parish during the nineteenth century. Part I reviews existing literature on the subject and looks at the physical and pre-urban background. It also provides a brief overview of the creation of the essential infrastructure of the suburb, from sewers to railways and from churches to music halls, and looks at the social and occupational background of the population as it grew with breathtaking rapidity from less than 3,000 in 1801 to 170,000 a century later.

Part II discusses the evidence for building cycles in Battersea. The myriad men responsible for building the houses are then examined. This was an industry which essentially remained a collection of hand crafts throughout the period, albeit with some increase in the scale of operations after c.1870. Almost all of the thousands of builders and others came from within a five-mile radius of Battersea, and few lasted more than five years, most considerably less. The speculative nature of housebuilding was always at present and left a trail of bankruptcies and lesser failures in its wake.

A classification of building estates according to the occupation of the initiator is proposed. Most were small operators who often failed to make the sure profits they expected when they set out. Case studies in Part Ill demonstrate that despite the degree of fragmentation in both estates and building, the operation of the various processes tended to produce homogeneous results in terms of the type and quality of housing, and of the tenants who occupied it, at leas: when new. This convergence often occurred despite the aspirations of landowners and developers, so that the supply and demand equation was usually in balance over a mid- to longer-term period, although there were severe cyclical fluctuations causing casualties among the many groups associated with the transformation of Battersea from an agricultural settlement with a substantial industrial base to a fully-fledged London suburb, larger than most provinicial towns

description: We study neutrino emission from a normal, ungapped, quark phase in the core of a compact star. Neutrino emission from non-interacting quark matter leads to an emissivity that scales as $ε\sim T^7$. We show that the emissivity is enhanced by a combination of Fermi liquid and non-Fermi liquid effects. Fermi liquid effects lead to an emissivity that scales as $ε\sim α_s T^6$, as originally shown by Iwamoto. We demonstrate that non-Fermi liquid effects further enhance the rate, leading to $ε\sim α_s^3 T^6\log(m/T)^2$, where $m$ is the electric screening scale and $m\gg T$ under the conditions found in compact stars. We show, however, that combined with non-Fermi liquid effects in the specific heat the enhancement in the emissivity only leads to a modest reduction in the temperature of the star at late times. Our results confirm existing bounds on the presence of ungapped quark matter in compact stars. We also discuss neutrino emission from superconducting phases with ungapped fermionic excitations.

title: A living life, a living death: a study of Bessie Head's writings as a survival strategy
Creators: name: Atkinson, Susan D.
Publisher: name: The Open University
Year: 1998

description: This thesis explores Bessie Head's writing as a survival strategy through which, by transforming her personal experience into imaginative literature, she was able to give meaning and purpose to a life under permanent threat from the dominant groups first in South Africa and later in Botswana. This threat included the destructive effect of the many fixed labels imposed upon her which included: a 'Coloured' woman; the daughter of a woman designated mad; an exile; a psychotic; a tragic black woman, a Third World woman writer. In my view, her endeavours to avoid and defeat such limited and static definitions produced work characterized by contradiction and paradox. In this way she asserted her right to survive and determined, like Makhaya in When Rain Clouds Gather, to establish a 'living life' in place of the 'living death that a man [sic] could be born into' (136 RC). Her preoccupations include her relationship to her absent mother, her feelings about women's sexuality, and her need for love, articulated throughout her writings in terms not only of the threats against her but also the ways in which she empowered herself, and thus survived. I have drawn on a combination of Bessie Head's unpublished letters and papers, her published writings, and relevant critical works in order to show how her writing was the mediating agent which related her preoccupations to her experiences, while also facilitating her ability to survive and finally to transcend the all-pervasive power structures which influenced her life and her sense of self. As she said in the last years of her life (with bitter understatement) ' I am no failure' (20.2.1986 KMM BHP).

description: A atividade pesqueira é considerada uma dessas atividades tradicionais da Amazônia, enquanto ligada ao próprio modo de vida região. É uma atividade muito importante, mas que não tem sido capaz de criar um dinamismo interno para o desenvolvimento local, especialmente enquanto mecanismo endógeno. Assim sendo, propõe-se neste artigo estudar as suas características, enquanto capazes ou não de dinamizar esse desenvolvimento local na região da Amazônia Legal. Isto implica verificar suas especificidades na região, indicando seus limites e potencialidades. A metodologia empírica principal utilizada neste estudo será os estudos de Arranjos Produtivos Locais – APL realizados pela Agência de Desenvolvimento da Amazônia – ADA, concomitante a uma análise com base na Matriz Insumo-Produto e de Contabilidade Social para os Estados do Pará, Amazonas e Amapá.

description: We present the ALPS (Algorithms and Libraries for Physics Simulations) project, an international open source software project to develop libraries and application programs for the simulation of strongly correlated quantum lattice models such as quantum magnets, lattice bosons, and strongly correlated fermion systems. Development is centered on common XML and binary data formats, on libraries to simplify and speed up code development, and on full-featured simulation programs. The programs enable non-experts to start carrying out numerical simulations by providing basic implementations of the important algorithms for quantum lattice models: classical and quantum Monte Carlo (QMC) using non-local updates, extended ensemble simulations, exact and full diagonalization (ED), as well as the density matrix renormalization group (DMRG). The software is available from our web server at http://alps.comp-phys.org.

description: Overcoming the influence of noise and imperfections in quantum devices is one of the main challenges for viable quantum applications. In this article, we present different protocols, which we denote as "superposed quantum error mitigation", that enhance the fidelity of single gates or entire computations by performing them in coherent superposition. Our results demonstrate that via our methods, significant noise suppression can be achieved for most kinds of decoherence and standard experimental parameter regimes. Our protocols can be either deterministic, such that the outcome is never post-selected, or probabilistic, in which case the resulting state must be discarded unless a well-specified condition is met. By using sufficiently many resources and working under broad assumptions, our methods can yield the desired output state with unit fidelity. Finally, we analyze our approach for gate-based, measurement-based and interferometric-based models, demonstrating the applicability in all cases and investigating the fundamental mechanisms they rely upon.

description: Two mechanisms for nonlinear mode saturation of the r-mode in neutron stars have been suggested: the parametric instability mechanism involving a small number of modes and the formation of a nearly continuous Kolmogorov-type cascade. Using a network of oscillators constructed from the eigenmodes of a perfect fluid incompressible star, we investigate the transition between the two regimes numerically. Our network includes the 4995 inertial modes up to n<= 30 with 146,998 direct couplings to the r-mode and 1,306,999 couplings with detuning< 0.002 (out of a total of approximately 10^9 possible couplings). The lowest parametric instability thresholds for a range of temperatures are calculated and it is found that the r-mode becomes unstable to modes with 13

Enhancement of Giant Rashba Splitting in BiTeI under Asymmetric Interlayer Interaction

description: We carry out density functional theory calculation to enhance the Rashba spin splitting (RSS) of BiTeI by modifying the interlayer interaction. It is shown that RSS increases as the Te layer approaches to adjacent Bi layer or the I layer recedes from the Bi layer. Our results indicate that the RSS can be sensitively increased by introducing a vacancy on the Te site to make effective Bi-Te distance shorter. It is also found that the difference of Te p orbital character between two spin-split bands increases when the RSS is developed along crystal momentum, which supports asymmetric interlayer interaction in the spin-split bands. Our work suggests that the modification of interlayer interaction is an effective approach in the modeling of the RSS in BiTeI and other layered materials.

description: We develop optimal protocols for efficient photon transfer in a cavity-QED network. This is executed through stimulated Raman adiabatic passage (STIRAP) scheme, where time-varying capacitive couplings (with carefully chosen sweep rate) play a key role. We work in a regime where semiclassical limit is valid and we investigate the dynamical chaos caused by the light-matter coupling. We show that this plays a crucial role in estimating the lower bound on the sweep rate for ensuring efficient photon transfer. We present Hermitian as well as an open quantum system extension of the model. Without loss of generality, we study the three cavity and four cavity case and our results can be adapted to larger networks. Our analysis is also significant in designing transport protocols aimed for nonlinear open quantum systems in general.

description: The recent progress of text-to-image generation has been recognized in architectural design. Our study is the first to investigate the potential of text-to-image generators in supporting creativity during the early stages of the architectural design process. We conducted a laboratory study with 17 architecture students, who developed a concept for a culture center using three popular text-to-image generators: Midjourney, Stable Diffusion, and DALL-E. Through standardized questionnaires and group interviews, we found that image generation could be a meaningful part of the design process when design constraints are carefully considered. Generative tools support serendipitous discovery of ideas and an imaginative mindset, enriching the design process. We identified several challenges of image generators and provided considerations for software development and educators to support creativity and emphasize designers' imaginative mindset. By understanding the limitations and potential of text-to-image generators, architects and designers can leverage this technology in their design process and education, facilitating innovation and effective communication of concepts.
