description: Objetivou-se, neste artigo, analisar a competitividade e as potencialidades da piscicultura no Lago de Três Marias em Minas Gerais, dado que é latente o desenvolvimento dessa atividade como alternativa econômica para a região. São utilizadas a visão de APL (Arranjo Produtivo Local), com contribuições da Nova Economia Institucional e de coordenação em sistemas agroindustriais, como modelos de análise. Como método para coleta de dados, foi realizado um levantamento de dados in loco por meio de entrevistas e da organização de um workshop com agentes participantes do APL. Foi possível concluir que, a despeito das grandes vantagens em termos de recursos naturais e apoio governamental, grande parte dos desafios para aumentar a competitividade da atividade está relacionada à consolidação das instituições e à melhoria da coordenação vertical e horizontal entre os agentes participantes. Uma vez que essas ações e definições estejam implementadas, é razoável supor que recursos e competências locais existentes serão mais bem aproveitados, gerando benefícios econômicos e sociais relevantes para uma região ainda pouco desenvolvida no Brasil, mas com potencial notável.

description: We present solutions for the late time evolution of cosmological tensor and scalar perturbations in a single-Randall-Sundrum brane world model. Assuming that the bulk is anti-de Sitter spacetime, the solutions for cosmological perturbations are derived by summing mode functions in Poincaré coordinate. The junction conditions imposed at the moving brane are solved numerically. The recovery of 4-dimensional Einstein gravity at late times is shown by solving the 5-dimensional perturbations throughout the infinite bulk. We also comment on several possibilities for having deviations from 4-dimensional Einstein gravity.

Novel bacterial strains, suitable for use in large-scale fermentation, for the maintenance and replication of Petit Plasmid
Creators: name: Solofondrazaintsoanirina, Rojopitiavana
Publisher: name: Zenodo
Year: 2024

description: I previously introduced a class of antibiotic-free small DNA vectors termed “Petit Plasmids”. These vectors can be maintained and replicated within engineered amino acid auxotrophic bacterial strains cultivated in a medium lacking one or more essential amino acids. In large-scale fermentation systems, these growing cells can scavenge lysed cells to obtain the essential amino acids, promoting the survival of cells lacking Petit Plasmid. To address this limitation, I present novel strains of engineered bacterial cells that require a specific inducing agent for growth in the absence of Petit Plasmid.

description: Мета. Експериментальне встановлення впливу конструкційних, режимних та технологічних параметрів процесу роботи гвинтового гранулятора кормів на якісні показники кормових гранул. Методи. Експериментальні дослідження та аналіз отриманих результатів проводилися з використанням методів планування багатофакторного експерименту та регресійного аналізу. Результати. В результаті експериментальних досліджень було отримано рівняння регресії у вигляді поліномів другого порядку, що характеризують залежність критеріїв оптимізації – температури гранул, втрат вологи в процесі гранулювання, кришимості та щільності гранул – від досліджуваних факторів. Висновки. Встановлено, що найбільший вплив на показники міцності (щільності та кришимості) гранул чинить діаметр отворів матриці гранулятора, а втрати вологи при гранулюванні кормосуміші за допомогою гвинтових грануляторів становлять 3-6% в залежності від режиму роботи гранулятора та початкової вологості сировини

description: A decisão de hedge simultâneo dos produtores de soja de Mato Grosso com contratos futuros de preço e taxa de câmbio da BOVESPA-BM&F foi analisada. Um modelo de hedge simultâneo do risco de preços e taxa de câmbio foi obtido e as eficiências de diferentes estratégias de hedge foram calculadas. As principais conclusões foram que o hedge simultâneo de risco de preços e a taxa de câmbio reduzem de forma acentuada o risco da receita total, comparativamente ao hedge de preços isolado. A mitigação do risco de taxa de câmbio, em conjunto com o de preços é fundamental para uma gestão estratégica dos exportadores de commodities.

description: A density wave in quark matter is discussed at finite temperature, which occurs along with the chiral condensation, and is described by a dual standing wave in scalar and pseudo-scalar condensates on the chiral circle. The mechanism is quite similar to that for the spin density wave suggested by Overhauser, and entirely reflects many-body effects. It is found that the chiral condensed phase with the density wave develops at a high-density region just outside the usual chiral-transition line in phase diagram. A magnetic property of the density wave is also elucidated.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. 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. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

A presente pesquisa caracteriza-se como um estudo descritivo de caráter qualitativo. É realizado um estudo de caso, utilizando-se de documentação e observação in loco, questionário, entrevista e focus group. Os dados obtidos possibilitaram o desenvolvimento de uma figura representativa dos aspectos envolvidos na criação de conhecimento. Os resultados demonstraram que, para a ocorrência da criação de conhecimento, é necessária a existência de grupos de relacionamento e de certa liderança em nível de propriedade, de comunidades de prática (CoPs) ou da cooperativa. A forma de conduzir os negócios pode afetar o modo como se dá a criação de conhecimento. Por exemplo, numa propriedade em que as pessoas buscam socializar, questionar e inovar constantemente evidencia-se haver maior espaço para transformar conhecimento tácito em explícito. O aspecto cultural e o estilo das relações, bem como a forma de conduzir os negócios podem afetar o modo como se dá a criação de conhecimento. Há um grande percurso entre o produtor rural ter conhecimento e a capacidade de torná-lo atitude que traga bons resultados nos negócios.

description: We study the index of 4d $\mathcal{N}=4$ Yang-Mills theory with $U(N)$ gauge group, focussing on the physics of the dual BPS black holes in $AdS_5\times S^5$. Certain aspects of these black holes can be studied from finite $N$ indices with reasonably large $N^2$. We make numerical studies of the index for $N\leq 6$, by expanding it up to reasonably high orders in the fugacity. The entropy of the index agrees very well with the Bekenstein-Hawking entropy of the dual black holes, say at $N^2=25$ or $36$. Our data clarifies and supports the recent ideas which allowed analytic studies of these black holes from the index, such as the complex saddle points of the Legendre transformation and the oscillating signs in the index. In particular, the complex saddle points naturally explain the $\frac{1}{N}$-subleading oscillating patterns of the index. We also illustrate the universality of our ideas by studying a model given by the inverse of the MacMahon function.

description: Let $Φ(N)$ denote the number of products of matrices $[ \begin{smallmatrix} 1 & 1 \\ 0 & 1 \end{smallmatrix}]$ and $[ \begin{smallmatrix} 1 & 0 \\ 1 & 1 \end{smallmatrix} ]$ of trace equal to $N$, and $Ψ(N)=\sum_{n=3}^N Φ(n)$ be the number of such products of trace between $3$ and $N$. We prove an asymptotic formula of type $Ψ(N) = c_1 N^2 \log N +c_2 N^2 + O_\varepsilon (N^{7/4+\varepsilon})$ as $N\to \infty$. As a result, the Dirichlet series $\sum_{n=1}^\infty Φ(n) n^{-s}$ has a meromorphic extension in the half-plane $\Re (s)>7/4$ with a single, order two pole at $s=2$. Our estimate also improves on an asymptotic result of Faivre concerning the distribution of reduced quadratic irrationals, providing an explicit upper bound for the error term.

description: In todays world, smartphones are a constant and almost indispensable companion in day-to-day life. A study from Eurostat shows that 74\% of Austrian individuals aged 16 to 74 use Internet over mobile phones. Therefore, it is important to know why and how modern devices can effect the personal privacy through wireless emissions. Especially if the mobile phone is not connected to an Access Point and Wi-Fi is turned on. There can be wireless emissions because of a regular occurring network discovery to detect nearby Access Points. In this master thesis an extensive data collection of Wi-Fi frames is created and analyzed. The evaluation of the collected data led to the result that capturing of Probe Requests which are used for network discovery can be misused to provide a feasible and cheap tracking solution. Even if MAC randomization is used, devices could be tracked for multiple days. Also a combination of randomized MAC addresses which use directed Probe Requests was recorded. Directed Probe Requests can render MAC randomization completely useless.

description: Graphene-based nanostructured systems and van-der-Waals heterostructures comprise a material class of growing technological and scientific importance. Joining materials with vastly different properties, polymer-graphene heterosystems promise diverse applications in surface- and nanotechnology, including photovoltaics or nanotribology. Fundamentally, molecular adsorbates are prototypical systems to study confinement-induced phase transitions exhibiting intricate dynamics, which require a comprehensive understanding of the dynamical and static properties on molecular time and length scales. Here, we investigate the dynamics and the structure of a single polyethylene chain on free-standing graphene by means of molecular dynamics simulations. In equilibrium, the adsorbed polymer is orientationally linked to the graphene as two-dimensional folded-chain crystallites or, at elevated temperatures, as a floating solid. The associated superstructure can be reversibly melted on a picosecond time scale upon quasi-instantaneous substrate heating, involving ultrafast heterogeneous melting via a transient floating phase. Our findings elucidate time-resolved molecular-scale ordering and disordering phenomena in individual polymers interacting with solids, yielding complementary information to collective friction and viscosity, and linking to recent experimental observables from ultrafast electron diffraction. We anticipate that the approach will help in resolving non-equilibrium phenomena of hybrid polymeric systems over a broad range of time and length scales.

description: Adotou-se como objetivo, neste trabalho, identificar as contribuições da inovação tecnológica para a competitividade e os seus impactos nas relações de trabalho em usinas de açúcar e álcool, localizadas na região noroeste do Paraná. Para tanto, realizou-se uma pesquisa do tipo descritiva, de natureza qualitativa e corte seccional, sendo os dados coletados por meio de entrevistas semiestruturadas, realizadas com gerentes envolvidos no processo produtivo. O referencial teórico utilizado contemplou uma revisão de literatura sobre inovação tecnológica, competitividade e relações de trabalho. Os resultados apontaram que a principal contribuição da inovação tecnológica para a competitividade das usinas é a redução de custos e, consequentemente, a maior lucratividade, devido ao aumento da produtividade alcançado pelo máximo aproveitamento da matéria-prima. No que tange às relações de trabalho, os principais impactos observados estão na área agrícola e industrial, em que a mecanização da colheita de cana-de-açúcar e a automação dos processos de fabricação de açúcar e álcool, respectivamente, trazem extinções e criações de postos de trabalho, além de realocação de pessoal.

description: Recently, the term blockchain has been on everyones lips due to the media hype which has emerged around the cryptocurrency Bitcoin. Soon the blockchain paradigm has become an inspiration for additional applications next to cryptocurrencies. One type of such applications are smart contracts, i.e. programs which are executed on a blockchain network and move digital assets according to arbitrary pre-specified rules. Utilizing the combination of cryptographically secure mechanisms of a blockchain and the possibility to execute programs on a blockchain network results in promising use cases for the public and the private sector. In order to run smart contracts, a platform such as Ethereum can be used. In contrast to a public smart contract platform, a private version allows to configure some blockchain-specific parameters when setting up the system. Examples of these configuration parameters are the time passing between two consecutive blocks, the size of blocks, the hardware of the nodes running the blockchain software or simply the size of the network. However, how these and other parameters of a private Ethereum smart contract platform affect the performance of the system is still poorly understood. Moreover, it is not clear to which extent these parameters scale and which parameters represent the bottleneck of such systems. In order to tackle this problem, this thesis introduces a novel concept for measuring the performance and scalability of private Ethereum smart contract platforms. This concept is practically implemented in a framework which allows to automatically deploy differently configured private Ethereum smart contract platforms on the cloud for the purpose of gathering performance-related data. Based on the gathered data, various charts were created which visualize the effects on performance when changing a specific parameter. The results of the data analysis conducted show that the effect of variations in one parameter is highly dependent on the configuration of other parameters as well, especially when running the system near its limits. Nevertheless, a structure which depicts the bottlenecks of current private Ethereum smart contract platforms has been identified. Further research may be conducted in order to support additional Ethereum clients and APIs.

description: We have analyzed single pulses from PSR J0737-3039B, the 2.8-s pulsar in the recently discovered double pulsar system, using data taken with the Green Bank Telescope at 820 and 1400 MHz. We report the detection of features similar to drifting subpulses, detectable over only a fraction of the pulse window, with a fluctuation frequency of 0.196 cycles/period. This is exactly the beat frequency between the periods of the two pulsars. In addition, the drifting features have a separation within a given pulse of 23 ms, equal to the pulse period of A. These features are therefore due to the direct influence of PSR J0737-3039A's 44-Hz electromagnetic radiation on PSR J0737-3039B's magnetosphere. We only detect them over a small range of orbital phases, when the radiation from the recycled pulsar PSR J0737-3039A meets our line of sight to PSR J0737-3039B from the side.

description: O termo capital social é considerado variável potencializadora da equação do desenvolvimento social e da prosperidade econômica regional. Isso porque facilita ações coordenadas, promovendo e aumentando a eficiência da sociedade por meio de características, tais como a confiança, a cooperação e a participação, podendo se tornar facilitadoras do desenvolvimento econômico e social. Objetivouse neste estudo analisar a existência e prevalência de capital social em um sítio cafeeiro no município de Poço Fundo, que produz café orgânico na região do Sul do estado de Minas Gerais. Para tanto, metodologicamente, recorreu-se a uma abordagem de multimétodo, o que implica em procedimentos de pesquisa quanti-qualitativa somados a uma técnica de triangulação. Com o estudo evidenciou-se que, na realidade observada, no sítio cafeeiro da região de Poço Fundo há formas de capital social como um recurso coletivo e redes mais densas e fechadas, nas quais a confiança por meio de condutas de cooperação e solidariedade permitiu aos cafeicultores orgânicos dessa região construir uma associação e, posteriormente, uma cooperativa com princípios de gestão participativa dentro da filosofia do fair trade. Essa relação restrita entre os produtores garantiu sua marca e garantia no mercado para atuarem num mercado extremamente competitivo.

Para tanto calcula-se o potencial importador dos blocos/países, o Índice de Vantagem Revelada das Exportações do Brasil e de seus principais concorrentes, o Índice de Orientação Regional, além de pesquisa bibliográfica das principais barreiras existentes. Os resultados, quanto ao potencial importador, indicam que a União Européia (UE) e a Comunidade dos Estados Independentes (CEI) constituem-se em mercados potenciais e promissores para a carne suína, respectivamente. Os resultados do cálculo das vantagens comparativas revelaram que o Brasil tem competitividade crescente no setor estudado para o período 1990-2005. As barreiras impostas revelaram-se muito elevadas. Enfim, constata-se alto grau de aceitação das exportações brasileiras de carne suína naqueles blocos que não têm barreiras sanitárias impeditivas.

description: As exigências de padrões de mercado têm demandado organização do setor produtivo para atendê-los. Algumas estruturas organizacionais permitem perceber as mudanças e fornecer incentivos para que essas sejam implementadas. A Produção Integrada de Frutas (PIF) surgiu como uma demanda do setor produtivo, que necessitava de um sistema de certificação e rastreabilidade. Objetivou-se, nesta pesquisa, verificar a importância das organizações (associações) de interesse privado, na cadeia produtiva da maçã no Brasil, que adotam a PIF, verificando como essas atuam com outras estruturas do setor produtivo. A metodologia consistiu, inicialmente, em estudo exploratório para conhecer se melhor as características do setor. Após essa etapa fez-se uma pesquisa descritiva e explicativa usando questionários e entrevistas semiestruturadas nas empresas, cooperativas e Ministério da Agricultura, Pecuária e Abastecimento (MAPA), incluindo a coordenação do Programa. Os participantes destacam a importância das organizações de interesse privado como impulsionador das mudanças, com uma participação nas atividades de capacitação, divulgação dos produtos e principalmente de melhorias da atividade, fazendo lobby junto ao Estado. Por parte do Estado, destaca-se que essas associações foram de grande importância para a adoção da PIF no Brasil.

description: In SUSY models, it is still possible to have large signals even if the current data on $K$ and $B$ systems are consistent with the CKM paradigm for flavor mixing and CP violation. I first discuss $b\to d$ and $b\to s$ transitions including time-dependent CP asymmetries in $B_d \to ϕK_s$, and usefulness of $B_s \to μ^+ μ^-$ to distinguish various SUSY breaking mechanisms. Then I will discuss some possible connections between B physics and cosmology: (i) B physics and electroweak baryogenesis within SUSY models, and (ii) the correlation between the neutralino dark matter scattering and $B (B_s \to μ^+ μ^-)$.

description: As the SKA is expected to be operational in the next decade, investigations of the radio sky in the range of 100 MHz to 10 GHz have become important for simulations of the SKA observations. In determining physical properties of galaxies from radio data, the radio SED is often assumed to be described by a simple power law, usually with a spectral index of 0.7 for all sources. Even though radio SEDs have been shown to exhibit deviations from this assumption, both in differing spectral indices and complex spectral shapes, it is often presumed that their individual differences cancel out in large samples. We constructed the average radio SED of radio-excess active galactic nuclei (RxAGN), defined as those that exhibit a 3 $σ$ radio luminosity excess with respect to the value expected only from contribution from star formation, out to z~4. We combined VLA observations of the COSMOS field at 1.4 GHz and 3 GHz with GMRT observations at 325 MHz and 610 MHz. To account for nondetections in the GMRT maps, we employed the survival analysis technique. We selected a sample of RxAGN out to z~4. We find that a sample of RxAGN can be described by a spectral index of $α_1=0.28\pm0.03$ below the break frequency $ν_b=(4.1\pm0.2)$ GHz and $α_2=1.16\pm0.04$ above, while a simple power-law model yields a single spectral index of $α=0.64\pm0.07$. By binning in 1.4 GHz radio luminosity and redshift, we find that the power-law spectral index, as well as broken power-law spectral indices, may increase for larger source sizes, while the power-law spectral index and lower-frequency (<4 GHz) broken power-law spectral index are additionally positively correlated with redshift.

description: We demonstrate the implementation of Grover's quantum search algorithm on a liquid state nuclear magnetic resonance (NMR) quantum computer using essentially pure states. This was achieved using a two qubit device where the initial state is an essentially pure ($ε=1.06\pm0.04$) singlet nuclear spin state of a pair of 1H nuclei arising from a chemical reaction involving para-hydrogen. We have implemented Grover's search to find one of four inputs which satisfies a function.

description: Por meio deste estudo, buscou-se avaliar a eficiência econômica da alocação dos recursos produtivos da cafeicultura no Sul de Minas Gerais. Os municípios pesquisados estão entre os maiores produtores do sul do Estado, a exemplo de Alfenas, Guaxupé, São Sebastião do Paraíso, Varginha e Três Pontas, totalizando 46 propriedades de café. Este estudo baseia-se nos princípios da teoria da produção e do custo e utiliza o modelo de Análise Envoltória de Dados para avaliar a eficiência econômica dos cafeicultores pesquisados. Os coeficientes técnicos referem-se aos anos agrícolas 2006/2007, 2007/2008 e 2008/2009, que foram ajustados para a safra 2008/2009. Em média, os cafeicultores apresentam eficiência econômica de 64,08%. Considerou-se o produtor de café economicamente eficiente aquele em que a medida de eficiência econômica (EE) fosse igual ou maior 90,0%, e o percentual de cafeicultores que atingiram esse escore mínimo de eficiência foi de 13,4%. Os resultados indicaram uso ineficiente dos recursos produtivos na maioria dos casos, tanto técnica quanto economicamente.

description: The Higgs potential of the standard model with an additional real Higgs singlet is studied in order to examine if it may allow the strongly first order electroweak phase transition. It is found that there are parameter values for which this model at the one-loop level with finite temperature effect may allow the desired phase transition. Those parameter values also predict that the masses of the neutral scalar Higgs bosons of the model are consistent with the present experimental bound, and that their productions in $e^+e^-$ collisions may be searched at the proposed ILC with $\sqrt s$ = 500 GeV in the near future.

description: The critical points of the two-layer Ising and Potts models for square lattice have been calculated with high precision using probabilistic cellular automata (PCA) with Glauber algorithm. The critical temperature is calculated for the isotropic and symmetric case (Kx=Ky=Kz=K), where Kx and Ky are the nearest-neighbor interactions within each layer in the x and y directions, respectively, and Kz is the interlayer coupling. The obtained results are 0.310 and 0.726 for two-layer Ising and Potts models, respectively, that are in good agreement with the accurate values reported by others.

description: We are interested in the application of Machine Learning (ML) technology to improve mathematical software. It may seem that the probabilistic nature of ML tools would invalidate the exact results prized by such software, however, the algorithms which underpin the software often come with a range of choices which are good candidates for ML application. We refer to choices which have no effect on the mathematical correctness of the software, but do impact its performance. In the past we experimented with one such choice: the variable ordering to use when building a Cylindrical Algebraic Decomposition (CAD). We used the Python library Scikit-Learn (sklearn) to experiment with different ML models, and developed new techniques for feature generation and hyper-parameter selection. These techniques could easily be adapted for making decisions other than our immediate application of CAD variable ordering. Hence in this paper we present a software pipeline to use sklearn to pick the variable ordering for an algorithm that acts on a polynomial system. The code described is freely available online.

description: Objectives: Multiple reasons for suboptimal treatment of breakthrough cancer pain (BTcP) have been reported in the literature. We aimed to ascertain the perception of physicians on the potential inappropriate use and prescription of rapid-onset opioids (ROOs) for breakthrough cancer pain (BTcP) and the causes thereof. Methods: Observational study based on an online survey addressed to doctors from different specialties (radiation oncology, medical oncology, anesthesia, palliative care and general practitioners) with experience in the management of BTcP in the Spanish public health setting. Results: A total of 114 eligible specialists mainly from radiation oncology (37.7%), medical oncology (24.6%) and pain units (18.4%) participated in the study. Most agreed on important aspects of BTcP management, such as their preference for ROOs or the need for early follow-up after treatment initiation. However, their answers revealed a lack of standardization of BTcP diagnosis. Half of respondents believed that their BTcP patients might misuse ROOs. Physicians polled believed that lack of training in pain management (71.9%) and inadequate BTcP diagnosis and evaluation (66.7%) were the greatest obstacles for prescribing opioids. Specialists also thought that they do not provide the necessary information to patients (51.8%) and caregivers (57.9%) to guarantee the correct use of these drugs. Conclusions: These results are of utmost importance as they highlight the need to increase physicians’ awareness of BTcP and its management and the need to improve communication with patients and their caregivers. Our findings also indicate the need for future research on the possible misuse of opioids in BTcP patients and its causes.

description: The celebrated Kitaev honeycomb model provides an analytically tractable example with an exact quantum spin liquid ground state. While in real materials, other types of interactions besides the Kitaev coupling ($K$) are present, such as the Heisenberg ($J$) and symmetric off-diagonal ($Γ$) terms, and these interactions can also be generalized to a triangular lattice. Here, we carry out a comprehensive study of the $J$-$K$-$Γ$ model on the triangular lattice covering the full parameters region, using the combination of the exact diagonalization, classical Monte Carlo and analytic methods. In the HK limit ($Γ=0$), we find five quantum phases which are quite similar to their classical counterparts. Among them, the stripe-A and dual Néel phase are robust against the $Γ$ term, in particular the stripe-A extends to the region connecting the $K=-1$ and $K=1$ for $Γ<0$. Though the 120$^\circ$ Néel phase also extends to a finite $Γ$, its region has been largely reduced compared to the previous classical result. Interestingly, the ferromagnetic (dubbed as FM-A) phase and the stripe-B phase are unstable in response to an infinitesimal $Γ$ interaction. Moreover, we find five new phases for $Γ\ne 0$ which are elaborated by both the quantum and classical numerical methods. Part of the space previously identified as 120$^\circ$ Néel phase in the classical study is found to give way to the modulated stripe phase. Depending on the sign of the $Γ$, the FM-A phase transits into the FM-B ($Γ>0$) and FM-C ($Γ<0$) phase with different spin orientations, and the stripe-B phase transits into the stripe-C ($Γ>0$) and stripe-A ($Γ<0$). Around the positive $Γ$ point, due to the interplay of the Heisenberg, Kiatev and $Γ$ interactions, we find a possible quantum spin liquid with a continuum in spin excitations.
