This paper explores our experiences as scholars in higher education who collaborate as part of an informal collective supporting the Feminist Pedagogy for Teaching Online digital guide[1]. We, the authors, have diverse professional and educational backgrounds; our areas of research interest also vary significantly. However, we have a passion for humanizing online learning experiences and practically applying feminist pedagogical tenets to these interactions. The purpose of this paper is to explore, through a process of self-reflection, our experiences as scholars in higher education as part of an informal collective supporting the Feminist Pedagogy for Teaching Online digital guide. To share our experiences as editors of this digital guide, we included our individual stories using a collaborative autoethnography approach. In our stories, we specifically discussed our interest in joining this collective of feminist scholars, the evolving nature of our efforts in support of the digital guide, the success experienced, the challenges that we encountered, and the internal and external support we received throughout this journey. Ideally, through this critical reflection, we can aid other collectives who already engage, or are considering engaging, in similar scholarly communication endeavors. [1] This digital scholarship project works towards communicating liberatory pedagogical principles for educators in digital modalities.

This paper develops an agentic framework that employs large language models (LLMs) for grounded persuasive language generation in automated copywriting, with real estate marketing as a focal application. Our method is designed to align the generated content with user preferences while highlighting useful factual attributes. This agent consists of three key modules: (1) Grounding Module, mimicking expert human behavior to predict marketable features; (2) Personalization Module, aligning content with user preferences; (3) Marketing Module, ensuring factual accuracy and the inclusion of localized features. We conduct systematic human-subject experiments in the domain of real estate marketing, with a focus group of potential house buyers. The results demonstrate that marketing descriptions generated by our approach are preferred over those written by human experts by a clear margin while maintaining the same level of factual accuracy. Our findings suggest a promising agentic approach to automate large-scale targeted copywriting while ensuring factuality of content generation.

We address the challenge of acquiring real-world manipulation skills with a scalable framework. We hold the belief that identifying an appropriate prediction target capable of leveraging large-scale datasets is crucial for achieving efficient and universal learning. Therefore, we propose to utilize 3D flow, which represents the future trajectories of 3D points on objects of interest, as an ideal prediction target. To exploit scalable data resources, we turn our attention to human videos. We develop, for the first time, a language-conditioned 3D flow prediction model directly from large-scale RGBD human video datasets. Our predicted flow offers actionable guidance, thus facilitating zero-shot skill transfer in real-world scenarios. We deploy our method with a policy based on closed-loop flow prediction. Remarkably, without any in-domain finetuning, our method achieves an impressive 81\% success rate in zero-shot human-to-robot skill transfer, covering 18 tasks in 6 scenes. Our framework features the following benefits: (1) scalability: leveraging cross-embodiment data resources; (2) wide application: multiple object categories, including rigid, articulated, and soft bodies; (3) stable skill transfer: providing actionable guidance with a small inference domain-gap.

We study generalized anti-self-dual instantons defined over Riemannian manifolds equipped with a parallel codimension-$4$ differential form. In particular, for product Riemannian manifolds possessing such a form, we study dimension reduction phenomena, finding a topological criterion for bundles which, when satisfied, allows for a complete characterization of dimension reduction for the corresponding moduli space of generalized ASD instantons. By establishing an integrability result for families of connections, we then deduce explicit descriptions for these moduli spaces, including those of Hermitian Yang--Mills connections, $G_2$-, and $\Spin(7)$-instantons. When one factor in the product is a $4$-manifold, we establish well-behaved compactifications for these moduli spaces.

The article is devoted to the modern development of high technologies and computer technology greatly enhanced the development of automated banking systems of banking sector organizations and allowed the synthesis of information and communication technologies for their formation.The main purpose of the article is to select the main indicators for assessing the level of financial security of the banking system of the state and identify promising areas of its development using forecasting models. In the process of research such analytical functions have been used: polynomial, exponential, power and logarithmic. The authors believe that the information and analytical provision of the financial security of the bank is an information provision that combines, on the one hand, information work, that is, ways, means and methods of collecting the necessary information, and on the other - analytical work, which includes forms and methods of information analysis and processing, which ensures an objective assessment of the situation and the adoption of a balanced management decision. As a result, forecast models were built for each of the indicators and also, it has been found that most indicators of the banking system of Ukraine in 2021-2023 will remain at “unsatisfactory” and “critical” levels. In conclusions it was proposed to introduce measures that would be aimed at improving the reliability and stability of the banking system of Ukraine.

The general relativistic Poynting-Robertson (PR) effect is a very important dissipative phenomenon occurring in high-energy astrophysics. Recently, it has been proposed a new model, which upgrades the two-dimensional (2D) description in the three-dimensional (3D) case in Kerr spacetime. The radiation field is considered as constituted by photons emitted from a rigidly rotating spherical source around the compact object. Such dynamical system admits the existence of a critical hypersurface, region where the gravitational and radiation forces balance and the matter reaches it at the end of its motion. Selected test particle orbits are displayed. We show how to prove the stability of these critical hypersurfaces within the Lyapunov theory. Then, we present how to study such effect under the Lagrangian formalism, explaining how to analytically derive the Rayleigh potential for the radiation force. In conclusion, further developments and future projects are discussed.

The long-term resilient property of ecosystems has been quantified as ecological robustness (RECO) in terms of the energy transfer over food webs. The RECO of resilient ecosystems favors a balance of food webs' network efficiency and redundancy. By integrating RECO with power system constraints, the authors are able to optimize power systems' inherent resilience as ecosystems through network design and system operation. A previous model used on real power flows and aggregated redundant components for a rigorous mapping between ecosystems and power systems. However, the reactive power flows also determine power systems resilience; and the power components' redundancy is part of the global network redundancy. These characteristics should be considered for RECO-oriented evaluation and optimization for power systems. Thus, this paper extends the model for quantifying RECO in power systems using real, reactive, and apparent power flows with the consideration of redundant placement of generators. Recalling the performance of RECO-oriented optimal power flows under N-x contingencies, the analyses suggest reactive power flows and redundant components should be included for RECO to capture power systems' inherent resilience.

Este artículo estudia la relevancia de un hecho en el que, hasta el momento, no había reparado la historia de la medicina, la historia del libro ni la filología: el Tratado breve de cirugía (1579) y el Tratado breve de medicina (1592) traducen y adaptan parte del contenido anatómico y quirúrgico que escribió Juan de Vigo en su Practica in arte chirurgica copiosa (1514). La propuesta es que este hecho no resta originalidad a los dos tratados del médico agustino fray Agustín Farfán, señalando que el tratamiento de la obra del médico del papa Julio II –además de otros factores más allá del texto– influyó en el desequilibrio editorial existente entre los dos tratados. Se concluye con una posible justificación del porqué el último tratado (1592) sería reeditado en 1610, ya bajo el beneficio de la Orden de San Agustín; determinamos una respuesta que atiende a cuestiones políticas, propias de una orden religiosa mendicante que fue de las primeras en convertirse en una institución criolla.

Cultural transmission is the domain-general social skill that allows agents to acquire and use information from each other in real-time with high fidelity and recall. In humans, it is the inheritance process that powers cumulative cultural evolution, expanding our skills, tools and knowledge across generations. We provide a method for generating zero-shot, high recall cultural transmission in artificially intelligent agents. Our agents succeed at real-time cultural transmission from humans in novel contexts without using any pre-collected human data. We identify a surprisingly simple set of ingredients sufficient for generating cultural transmission and develop an evaluation methodology for rigorously assessing it. This paves the way for cultural evolution as an algorithm for developing artificial general intelligence.

Engineering methods are centered around traditional notions of decomposition and recomposition that rely on partitioning the inputs and outputs of components to allow for component-level properties to hold after their composition. In artificial intelligence (AI), however, systems are often expected to influence their environments, and, by way of their environments, to influence themselves. Thus, it is unclear if an AI system's inputs will be independent of its outputs, and, therefore, if AI systems can be treated as traditional components. This paper posits that engineering general intelligence requires new general systems precepts, termed the core and periphery, and explores their theoretical uses. The new precepts are elaborated using abstract systems theory and the Law of Requisite Variety. By using the presented material, engineers can better understand the general character of regulating the outcomes of AI to achieve stakeholder needs and how the general systems nature of embodiment challenges traditional engineering practice.

En el presente estudio se evaluó el efecto de los extractos acuosos (decocción y maceración acuosa) y etanólico de dos especies del género Cylindropuntia sobre el crecimiento micelial de Fusarium sp. y Aspergillus sp. en condiciones in vitro. Los extractos se realizaron de cladodios de C. imbricata y C. leptocaulis en tres concentraciones (10 %, 20 % y 30 %) y se añadieron a cajas Petri para formar un medio de cultivo extracto-agar nutritivo. Los medios de cultivo se inocularon con las diferentes cepas fitopatógenas y se incubaron por 10 días y se midió el crecimiento del micelio de cada una de las cepas en cada uno de los tratamientos y cada concentración cada 24 horas. Los resultados mostraron diferencias significativas entre los extractos de las plantas. C. imbricata presentó una mayor estimulación del crecimiento micelial con respecto a la obtenida de C. leptocaulis. Aspergillus sp. fue la cepa que presentó el mayor crecimiento micelial y Fusarium sp. presentó un menor crecimiento. El extracto etanólico presentó un mayor porcentaje de crecimiento micelial, seguido de los extractos obtenidos de la decocción y los que presentaron un menor crecimiento micelial fueron los obtenidos por maceración acuosa. Las concentraciones del 30 % fueron las que presentaron un mayor crecimiento micelial, seguida de las concentraciones del 20 %, y finalmente las concentraciones del 10 %. Nosotros concluimos que estos extractos no presentaron un efecto inhibitorio en el crecimiento de micelio de estos hongos fitopatógenos; al contrario, los extractos de ambas especies estimularon el crecimiento de estos hongos.

Background: Peer review is a necessary but costly and time-consuming process to identify good-quality and methodologically sound articles and improve them before publication. Finding good peer reviewers is often difficult.Objective: To identify the incentives that make Iranian biomedical researchers accept invitations to be a peer reviewer and factors that affect these incentives.Methods: Twelve reviewers selected at random from the reviewers pool of each of 26 biomedical journals published from Fars province, Iran, were surveyed using a questionnaire that we had developed and tested in a pilot study of 30 reviewers (Cronbach’s alpha of 0.779). The data included the reviewers’ demographics, history of their reviews, and choice of 11 reasons each for accepting or declining the invitation to review.Results: A total of 233 reviewers completed the questionnaire. The most important reasons for accepting the invitation to review were the journal’s practice to publish the names of the reviewers alongside the article they had reviewed, acknowledgement by the journals by publishing the names of reviewers once a year, free access to journals’ content, and lower publication charges as authors. The most common reasons to decline the invitation were lack of time, busy schedules, and lack of sufficient incentive to review.Conclusion: Acknowledgement by the journal, offering to publish the names of reviewers alongside the articles they had reviewed, and monetary rewards will be effective incentives for biomedical researchers in Iran to serve as peer reviewers.

Due to their broad application to different fields of theory and practice, generalized Petersen graphs $GPG(n,s)$ have been extensively investigated. Despite the regularity of generalized Petersen graphs, determining an exact formula for the diameter is still a difficult problem. In their paper, Beenker and Van Lint have proved that if the circulant graph $C_n(1,s)$ has diameter $d$, then $GPG(n,s)$ has diameter at least $d+1$ and at most $d+2$. In this paper, we provide necessary and sufficient conditions so that the diameter of $GPG(n,s)$ is equal to $d+1,$ and sufficient conditions so that the diameter of $GPG(n,s)$ is equal to $d+2.$ Afterwards, we give exact values for the diameter of $GPG(n,s)$ for almost all cases of $n$ and $s.$ Furthermore, we show that there exists an algorithm computing the diameter of generalized Petersen graphs with running time $O$(log$n$).

As a modified gravity theory that introduces new gravitational degrees of freedom, the generalized SU(2) Proca theory (GSU2P for short) is the non-Abelian version of the well-known generalized Proca theory where the action is invariant under global transformations of the SU(2) group. This theory was formulated for the first time in Phys. Rev. D 94 (2016) 084041, having implemented the required primary constraint-enforcing relation to make the Lagrangian degenerate and remove one degree of freedom from the vector field in accordance with the irreducible representations of the Poincaré group. It was later shown in Phys. Rev. D 101 (2020) 045008, ibid 045009, that a secondary constraint-enforcing relation, which trivializes for the generalized Proca theory but not for the SU(2) version, was needed to close the constraint algebra. It is the purpose of this paper to implement this secondary constraint-enforcing relation in GSU2P and to make the construction of the theory more transparent. Since several terms in the Lagrangian were dismissed in Phys. Rev. D 94 (2016) 084041 via their equivalence to other terms through total derivatives, not all of the latter satisfying the secondary constraint-enforcing relation, the work was not so simple as directly applying this relation to the resultant Lagrangian pieces of the old theory. Thus, we were motivated to reconstruct the theory from scratch. In the process, we found the beyond GSU2P.

We investigate a foliation of Schwarzschild spacetime determined by observers freely falling in the radial direction. This is described using a generalisation of Gullstrand-Painlevé coordinates which allows for any possible radial velocity. This foliation provides a contrast with the usual static foliation implied by Schwarzschild coordinates. The $3$-dimensional spaces are distinct for the static and falling observers, so the embedding diagrams, spatial measurement, simultaneity, and time at infinity are also distinct, though the $4$-dimensional spacetime is unchanged. Our motivation is conceptual understanding, to counter Newton-like viewpoints. In future work, this alternate foliation may shed light on open questions regarding quantum fields, analogue gravity, entropy, energy, and other quantities. This article is aimed at experienced relativists, whereas a forthcoming series is intended for a general audience of physicists, mathematicians, and philosophers.

The renaissance of General Relativity witnessed considerable progress regarding both understanding and justifying Einstein's equations. Both general relativists and historians of the subject tend to share a view, General Relativity exceptionalism. But does some of the renaissance progress in understanding and justifying Einstein's equations owe something to particle physics egalitarianism? If so, how should the historiography of gravitation and Einstein's equations reflect that fact? The idea of a graviton mass has a 19th century Newtonian pre-history in Neumann's and Seeliger's long-distance modification of gravity, which (especially for Neumann) altered Poisson's equation to give a potential $e^{-mr}/r$ for a point mass, improving convergence for homogeneous matter. Einstein reinvented the idea before introducing his faulty analogy with $Λ$. This confusion was first critiqued by Heckmann in the 1940s (without effect) and by Trautman, DeWitt, Treder, Rindler, and Freund et al. in the 1960s, and especially more recently by Schücking, but it has misled North, Jammer, Pais, Kerszberg, the Einstein Papers, and Kragh. The error is difficult to catch if one has an aversion to perturbative thinking, but difficult to make if one thinks along the lines of particle physics. The $Λ$-graviton mass confusion not only distorted the interpretation of Einstein's theory, but also obscured a potentially serious particle physics-motivated rivalry (massless vs. massive spin 2). How could one entertain massive spin 2 gravity if $Λ$ is thought already analogous to the Neumann-Seeliger scalar theory? Historiography, like physics, is best served by overcoming the divide between the two views of gravitation.
