description: We present an accurate, efficient and massively parallel finite-element code, DFT-FE, for large-scale ab-initio calculations (reaching $\sim 100,000$ electrons) using Kohn-Sham density functional theory (DFT). DFT-FE is based on a local real-space variational formulation of the Kohn-Sham DFT energy functional that is discretized using a higher-order adaptive spectral finite-element (FE) basis, and treats pseudopotential and all-electron calculations in the same framework, while accommodating non-periodic, semi-periodic and periodic boundary conditions. We discuss the main aspects of the code, which include, the various strategies of adaptive FE basis generation, and the different approaches employed in the numerical implementation of the solution of the discrete Kohn-Sham problem that are focused on significantly reducing the floating point operations, communication costs and latency. We demonstrate the accuracy of DFT-FE by comparing the energies, ionic forces and periodic cell stresses on a wide range of problems with popularly used DFT codes. Further, we demonstrate that DFT-FE significantly outperforms widely used plane-wave codes---both in CPU-times and wall-times, and on both non-periodic and periodic systems---at systems sizes beyond a few thousand electrons, with over $5-10$ fold speedups in systems with more than 10,000 electrons. The benchmark studies also highlight the excellent parallel scalability of DFT-FE, with strong scaling demonstrated on up to 192,000 MPI tasks.

description:
This paper discusses the implications of the newly adopted European Union Directive on Combating Violence against Women and Domestic Violence considering the utmost importance of addressing cyber violence against women and girls. We begin by an overview of the existing literature and the main topics related to cyber violence against women and girls, as we try to highlight some of the key challenges to tackling this phenomenon. This is followed by a description of the current situation in Bulgaria with respect to preventing violence against women and protecting survivors. We then centre on the importance of the newly adopted EU Directive and some of its key provisions. Based on the obligations borne out of the Directive and good practices from other European countries, we propose several policy recommendations that decision- and policymakers in Bulgaria may consider for the implementation of the new Directive. These relate to the need to adopt relevant and recent international and regional documents, ensure the collection of comprehensive data on cyber violence against women and stimulate the collaboration among different stakeholders

description: This case study of English Language Arts (ELA) teachers' experiences was conducted to explore whether ELA teachers are able to take students’ interests and identities into account when building their required reading curricula. Non-probability sampling was used to select eight high school English teachers from across North Carolina. Teachers then participated in semi-structured interviews, in which they were questioned on a variety of elements regarding their curriculum development process, their required reading material selection process, their methods for accounting for student interest and identities, their collaboration with school librarians, and more. This study will build understanding on the influences that affect high school ELA teachers’ ability to account for students’ interests and identities in their curricula, and how they do so.

description:
Pornographic deepfakes are a category of digital sexual offences that have been persistently rising, driven by the rapid progress in AI technology. In 2024, South Korea experienced a widespread crisis involving pornographic deepfakes that predominantly affected women, including minors. The feminist reaction to this case has been lightning-fast: mobilisations have transitioned from online to offline, also receiving support from abroad. This research aims to highlight the gendered dimension of technological innovations as well as the awareness of digital feminists on this matter from a technofeminist perspective. Particularly, it examines the activism of South Korean and Chinese feminists opposing pornographic deepfakes via hashtag campaigns. This study relies on qualitative content analysis of online posts from Instagram and two country-specific digital platforms, Naver in South Korea and Xiaohongshu in the People’s Republic of China, to examine the timeline and dynamics of the mobilisations’ building process in South Korea and among the Chinese diaspora. The discussion explores the characteristics, practices and claims of these mobilisations. Additionally, it presents an overview of recent legislative developments regarding deepfakes at both the international level and within South Korea and China. The findings aim to 1) enhance understanding of the digital feminist movements in both countries and their alliance, and 2) amplify the arguments and demands of the movement under study.

description: We present experimental evidence for coexisting periodic attractors in a semiconductor laser subject to external optical injection. The coexisting attractors appear after the semiconductor laser has undergone a Hopf bifurcation from the locked steady state. We consider the single mode rate equations and derive a third order differential equation for the phase of the laser field. We then analyze the bifurcation diagram of the time periodic states in terms of the frequency detuning and the injection rate and show the existence of multiple periodic attractors.

description: Background: Agroforestry (AF) and Mixed Farming (MF) are multifunctional systems that have been in use for centuries, but represent much untapped potential for modern solutions. AF and MF were severely neglected in policy making during the last 50 years for further industrialisation in agricultural systems. The negative consequence of this industrialisation on biodiversity, pollution to water, soil and air are becoming more apparent, as well as the need for more radical re-designs of farming systems. Despite many already known benefits of AF and MF systems, direct policies aimed at supporting and developing these systems remain a minority, both in Europe and internationally. AF and MF systems could be at the centre of this transformation routed in a food systems approach and the principles of agroecology for Europe.
Chance-Constrained Shrunken-Primal-Dual Subgradient (CC-SPDS) Approach for Decentralized Electric Vehicle Charging Control

description: In this paper, we develop a chance-constrained decentralized electric vehicle (EV) charging control framework to achieve "valley-filling" meanwhile meeting individual charging requirements and satisfying distribution network constraints. The control design is formulated as an optimization problem with a stochastic non-separable objective function and globally coupled chance constraints. We propose a novel chance-constrained shrunken-primal-dual subgradient (CC-SPDS) algorithm to support the chance-constrained decentralized control scheme and verify its efficacy and convergence with a representative distribution network model.

description: In this dissertation, I examine a former sixties era hippie commune from the things and memories its residents have left behind. I focus on the intersections of memories, materialities, identities and systems of signification in order to suggest the following: that we might consider through archaeological, anthropological, and oral historical analyses the value of a genealogy of the sixties alongside histories of the era; that plastic presents a challenging archaeological issue (one of method and curation) while simultaneously reifying a social sense of its artificiality as an artifact of New Buffalo and a present-fact of speech (i.e. referring metaphorically to things as ‘plastic’, meaning false or artificial); that considerations of a ‘hippie’ work ethic might be productively brought to bear upon contemporary concerns about work and labor, but also might unpack our understandings of work and labor in American history; that playing primitive is a performance of citation and appropriation, a process of the inauthentic mimesis creating an authentic new (problematic) identity; and that artifacts and other objects shape (even re-appropriate) memories as much as they are re-made by them, and that recent historical artifacts can open up interesting collaborative analytical spaces when brought into actual conversation with site inhabitants, residents, and visitors. I aim to synthesize a number of threads, a number of different thought clusters throughout this dissertation in an effort to unpack anew questions of authenticity, of performing primitive as a kind of ‘Indian play’, or cultural appropriation, while also articulating a kind of identity creation that is aesthetic, political and counter to hegemonic and dominant traditions and forms. This work combines original field research at the site of New Buffalo commune in Arroyo Hondo, NM (in Taos County) and among the New Buffalos.

description: In electrical contacts, thin films of nickel and gold or silver are traditionally plated on top of a copper base plate to provide corrosion resistance and wear protection. Most recently, the rising cost of noble metals and intensified competition in manufacturing technology has driven the industry towards thinner plating layers, which gives rise to questions regarding how interfacial contact and wear is affected by plating thickness and material characteristics. This study uses a combination of finite element analysis and ex-situ wear measurement to determine the effect of gold plating thickness on wear performance under linear reciprocating sliding contact. Correlations between predicted and measured results lead to insight into the stress state within the multi-layer system under contact conditions as well as a wear map for gold platings that can be used to inform future connector designs. The middle layer material, Ni, is relatedly inexpensive, but takes a relatively long time to deposit. Because this deposition time has a direct influence on the cost of manufacturing, it is important to reduce the Ni thickness as well. This project thus determines how different combinations of Ni and Au properties influence wear and subsurface layer exposure, which is critical for determining the makeup of future, low-cost, connector designs.

description: A nonlocal interface equation is derived for two-phase fluid flow, with arbitrary wettability and viscosity contrast c=(mu_1-mu_2)/(mu_1+mu_2), in a model porous medium defined as a Hele-Shaw cell with random gap b_0+delta b. Fluctuations of both capillary and viscous pressure are explicitly related to the microscopic quenched disorder, yielding conserved, non-conserved and power-law correlated noise terms. Two length scales are identified that control the possible scaling regimes and which scale with capillary number as ell_1 ~ b_0(c Ca)^{-1/2} and ell_2 ~ b_0 Ca^{-1}. Exponents for forced fluid invasion are obtained from numerical simulation and compared with recent experiments.

description: The behaviour of a driven double well Duffing-van der Pol (DVP) oscillator for a specific parametric choice ($\mid α\mid =β$) is studied. The existence of different attractors in the system parameters ($f-ω$) domain is examined and a detailed account of various steady states for fixed damping is presented. Transition from quasiperiodic to periodic motion through chaotic oscillations is reported. The intervening chaotic regime is further shown to possess islands of phase-locked states and periodic windows (including period doubling regions), boundary crisis, all the three classes of intermittencies, and transient chaos. We also observe the existence of local-global bifurcation of intermittent catastrophe type and global bifurcation of blue-sky catastrophe type during transition from quasiperiodic to periodic solutions. Using a perturbative periodic solution, an investigation of the various forms of instablities allows one to predict Neimark instablity in the $(f-ω)$ plane and eventually results in the approximate predictive criteria for the chaotic region.

Even in such a case, it is known that the gravitational particle production in an expanding universe may lead to a correct relic abundance depending on the inflation scale and the mass of dark matter particle. We provide a comprehensive and systematic analysis of the gravitational particle production of fermionic and vectorial dark matter, and emphasize that particles which are much heavier than the Hubble parameter but lighter than inflaton can also be produced abundantly.

We explore the full range of energies characterizing the active phase. The model exhibits strong non-ergodic features by settling into limit-cycles whose period depends on the energy and initial conditions. The asymptotic activity $ρ_a$ (topplings density) shows, as a function of energy density $ζ$, a devil's staircase behaviour defining a symmetric energy interval-set over which also the period lengths remain constant. The properties of $ζ$-$ρ_a$ phase diagram can be traced back to the basic symmetries underlying the model's dynamics.

Deterioration of Woman's Mental Health in Gilman's the Yellow Wallpaper

Publisher: name: Zenodo
Year: 2025

description: Charlotte Perkins Gilman’s “The Yellow Wallpaper” stands as a critical examination of thesuffocating patriarchy of its verse, one that contributes to the decreasing mental health of women.The plot of the paper centers around the narrator’s psychological decline, as the "rest cure" whichhad become a popular treatment prescribed to women who were dubbed 'nervous persons' in the19th century, took a devastating toll on her mind. The paper demonstrates, through an examinationof the narrator’s descent into madness, the ways in which restrictive gender roles, medicalmisogyny, and social conventions work together to inhibit female autonomy and intellectualexpression. The article, which proceeds to explore Gilman’s life—her suffering from depressionand her treatment by Dr. Weir Mitchell—makes a direct link between the tale and the real-life maledominated medical practices. Additionally, the paper explores the larger scope of late 19th centurysocio-cultural context surrounding marriage and work, and the restrictions imposed on women inboth areas. The diagnosis of women’s conditions as hysteria or nervous depression, mostlydetermined by their reproductive functions, provides further insight on how systematic theoppression of women was by medical practitioners. The yellow wallpaper itself symbolizes femaleentrapment, and serves as a powerful metaphor for a psychological rebellion. Approaching TheYellow Wallpaper with a feminist lens, this analysis demonstrates that Gilman provides us withnot simply the individual account of a woman driven to mental breakdown, but wider commentaryon the systemic forces of gender inequality and societal norms that render women alienated. Thenarrator's ultimate breakdown, represented by the last of her wallpaper, is an expression of tragicidentity and self-violating defiance. The story powerfully reflects the disregard for women’s voicesand the dreadful effects that stem from fertilizing the soil of their psychological and emotionalneeds.

description: Gundrada, the wife referred to in the title, is one of those historical characters, whose death conferred on them an importance they did not have in life. Romanticism turned her into a princess who set out with her husband across the snowy Alps towards the shrine of the Apostle Peter in Rome. She was certainly no royal figure and probably no pilgrim either. Her real identity and its significance are discussed in this paper. But it was her untimely death, burial and re-burial that set in train a series of remarkable events that gave her a place of permanent importance in the art of medieval Europe. These events are unravelled and analysed. The story is brought up to date, but 1992 is not the end of the journey, merely a resting-place on the way. References will be made throughout to details that will be found in the Appendix. These include the Warenne tombslab and inscription , plus the Gundrada tombslab, its inscription and decoration; the latter is assisted by a scale diagram.

description: We present the most general rotating black hole solution of five-dimensional N=4 superstring vacua that conforms to the ``no hair theorem''. It is chosen to be parameterized in terms of massless fields of the toroidally compactified heterotic string. The solutions are obtained by performing a subset of O(8,24) transformations, i.e., symmetry transformations of the effective three-dimensional action for stationary solutions, on the five-dimensional (neutral) rotating solution parameterized by the mass m and two rotational parameters $l_1$ and $l_2$. The explicit form of the generating solution is determined by three $SO(1,1)\subset O(8,24)$ boosts, which specify two electric charges $Q_1^{(1)}, Q_{2}^{(2)}$ of the Kaluza-Klein and two-form U(1) gauge fields associated with the same compactified direction, and the charge Q (electric charge of the vector field, whose field strength is dual to the field strength of the five-dimensional two-form field). The general solution, parameterized by 27 charges, two rotational parameters and the ADM mass compatible with the Bogomol'nyi bound, is obtained by imposing $[SO(5)\times SO(21)]/[SO(4)\times SO(20)]\subset O(5,21)$ transformations, which do not affect the five-dimensional space-time. We also analyze the deviations from the BPS-saturated limit.

description: With its destabilizing shifts away from mercantilism toward liberal economics, early nineteenth-century Britain generated an increasingly powerful class of technocrats, including architects and builders, in design and construction. This burgeoning professional group involved in architecture, planning, and building directed processes, products, and technologies of construction toward maintaining societal order. In doing so, they cemented their social hierarchical status. Following abolition of the slave trade in 1807 and emancipation from 1833-1838, architects and builders had to adapt their techniques of communication and labor management, and adjust their building practices to material and technological innovations. In contrast to heroic narratives of industrial progress and optimism that conventionally dominated histories of modern architecture, figures of apprehension, anxiety, and anticipation more appropriately encapsulate the consequential events of this period. Through empirical analyses of small-scale techniques of drawing and building, this dissertation renders the general transition from rigid, mercantilist arrangements aligned with economies of enslavement toward ideologies of free trade, increasingly widespread wage labor regimes, and liberalism more broadly, into legible, tangible forms. Using as heuristics architectural technologies for preempting, mitigating, and suppressing fires—planning, constructional assemblies, mechanisms, materials, regulations, financing, and legislation—I demonstrate that preventing undesirable occurrences governed a heterogeneous array of activities. These ranged from English architects' professionalization initiatives, to plans for evacuating people from and extinguishing fires in theaters, to labor management in West Indian military outposts, to fire insurance offices that spread their risk profiles by indemnifying Caribbean sugar plantations beginning in the late eighteenth century. Thus capital and uncertainty went hand in hand as elements in conveying wealth, as architects and others involved in building at once made risk both fungible and material.

description: We study the dynamics of systems with different time scales, when access only to the slow variables is allowed. We use the concept of Finite Size Lyapunov Exponent (FSLE) and consider both the case when the equations of motion for the slow components are known, and the situation when a scalar time series of one of the slow variables has been measured. A discussion on the effects of parameterizing the fast dynamics is given. We show that, although the computation of the largest Lyapunov exponent can be practically infeasible in complex dynamical systems, the computation of the FSLE allows to extract information on the characteristic time and on the predictability of the large-scale, slow-time dynamics even with moderate statistics and unresolved small scales.

description: Delphi is a powerful technique used to seek answers to appropriate questions. The purpose of this paper is to provide an overview of the Delphi technique as a research method. This paper discusses the scientific merit of the Delphi technique by investigating on 41 studies of Journal of Agricultural Education from 1981 to 2013, and 2 studies of Journal of Agricultural Science and Technology. The results showed that there is no general agreement on using indexes in different rounds of Delphi technique; however, according to the frequencies of using indexes in different studies, the following suggestions are presented. The favourable number of panel of experts is between 10 to 20. Purposive sampling method is used for selecting the panel members. Usually a three rounds of Delphi method is used. One question is designed in round one. Mean and standard deviation indexes are used for passing from round two to round three and agreement level of 70 present is used for achieving expert's consensus in round three.
Euclidean Approach to the Entropy for a Scalar Field in Rindler-like Space-Times

description: The off-shell entropy for a massless scalar field in a D-dimensional Rindler-like space-time is investigated within the conical Euclidean approach in the manifold $C_\be\times\M^N$, $C_\be$ being the 2-dimensional cone, making use of the zeta-function regularisation. Due to the presence of conical singularities, it is shown that the relation between the zeta-function and the heat kernel is non trivial and, as first pointed out by Cheeger, requires a separation between small and large eigenvalues of the Laplace operator. As a consequence, in the massless case, the (naive) non existence of the Mellin transform is by-passed by the Cheeger's analytical continuation of the zeta-function on manifold with conical singularities. Furthermore, the continuous spectrum leads to the introduction of smeared traces. In general, it is pointed out that the presence of the divergences may depend on the smearing function and they arise in removing the smearing cutoff. With a simple choice of the smearing function, horizon divergences in the thermodynamical quantities are recovered and these are similar to the divergences found by means of off-shell methods like the brick wall model, the optical conformal transformation techniques or the canonical path integral method.

description: This exploratory study examined maternal attitudes, subjective norms and food selection behaviors of 31 mothers (mean age 29.6 years, 50% Hispanic, 34% Black, 47% ≤ high school, 31% marginal health literacy, 71% Women, Infants and Children program participants) for their 2 and 3-year-old children (n=32, 50% female, 34.4% overweight/obese, 72% breastfed during infancy) to identify factors associated with childhood overweight. The Theory of Reasoned Action was used to examine relationships between variables of interest. Subjects were recruited from two primary care sites. Measurements included 5 surveys, child anthropometric measures and a simulation exercise to identify types and quantities of food mothers offered to their child. Selected food items were weighed and organized by food group and compared to USDA recommendations by child's age, gender and activity level. Data were analyzed using descriptive statistics, Spearman's rho correlation coefficients, and multivariate linear regression modeling. On average, mothers offered their children more fruit (237%) and meat (153%) but less vegetables (75%), dairy (79%) and grain (65%) than what is recommended. Mothers of 2 year olds selected greater quantity of food compared to mothers of 3 year old children for all food groups except dairy (p <0.05). Demographic, normative beliefs, maternal attitudes and health literacy meeting criteria were entered into multivariate regression models to predict behavioral intent. Final models explained 13% (dairy- restrictive attitude); 28% (grain- child's age, maternal BMI, physical activity); 40% (fruit-child's age, maternal education, normative belief, and health literacy); 44% (calories- child's age, normative beliefs for all food groups, restrictive attitude); 38% (meat- child's age, Hispanic ethnicity, normative belief) and 51% (vegetable- child's age, television viewing, normative belief and health literacy) of the variance of behavioral intent for the respective food groups. Normative beliefs and health literacy are potentially modifiable. Therefore, appraisal of maternal normative beliefs about dietary recommendations for children and health literacy may identify children at risk for overweight and obesity.

description: Island Copper Mine ceased operation in 1995 after having operated its open pit and concentrator for 24 years. During this time, the operation produced 1.3 billion kilograms of copper, 31 million kilograms of molybdenum, 31.7 million grams of gold and 336 million grams of silver. A closure plan was submitted to the Vancouver Island Mine Development Review Committee in 1994. Following comprehensive reviews, additional information was submitted in 1996. Acceptance of the plan was given in 1998. Progressive reclamation at the mine has been ongoing since the 1970's, Reclamation plans address the need for a forest cover that is designed to move through succession, productive terrestrial wildlife habitat and a sustainable marine environment along the shoreline of the Beach Dump. Areas of maturing trees are interspersed with open grassy areas providing both food and shelter for wildlife. Forest productivity is developed following successional processes with Red Alder serving as a nurse crop for subsequent conifer growth. A total of over 1/2 million trees have been planted on mine site areas. A total of 759 ha have been reclaimed out of a total disturbance of 769 ha. The revegetation strategy developed for the Island Copper Mine is based on the natural successional patterns that operate in the area. Red Alder initially colonizes disturbed sites. Amelioration of harsh site conditions by the alder creates sites in which conifers can thrive. Conifer growth under an alder canopy is greater than conifer growth without the alder, Nitrogen and moderated site conditions are believed to be responsible for this. Special revegetation areas such as wetlands to treat drainage water and to provide diversity for wildlife: have been developed in selected locations on the mine site. This paper presents a synopsis of the revegetation work that has been conducted at the Island Copper Mine. The role of Red Alder in the reclamation of mine disturbances is explored.

description: Multifunctional agriculture (MFA) has emerged as a key concept in science and politics with respect to the future of agriculture and rural development in the recent decade. Overall, MFA implies that in addition to their main function in production and support of rural livelihood, the agricultural activities have some other advantages for the environment including the conservation of water and soil resources and the enhancement of food security. This paper takes a look at the benefits of MFA as a concept and path toward agricultural development from an integrated perspective within the framework of sustainable development. Also, it tries to clarify the distinction between MFA and conventional agriculture in sustainable development approaches.

description: A six-parameter family of five-dimensional black hole solutions is constructed which are labeled by their mass, two asymptotic scalar fields and three charges. It is shown that the Bekenstein-Hawking entropy is exactly matched, arbitrarily far from extremality, by a simple but mysterious duality-invariant extension of previously derived formulae for the number of D-brane states in string theory.

On tensionless string field theory in AdS$_3$

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We report on progress in formulating a field theory of tensionless strings in $AdS_3$, starting from the dual large-$N$ symmetric orbifold CFT. We propose a set of field equations which are gauge invariant under the higher spin algebra of the theory, the `Higher Spin Square'. The massless higher spin sector is captured by a Chern-Simons gauge field, while the matter sector is described by unfolded equations similar to those appearing in Vasiliev theory. Our equations incorporate the full perturbative spectrum of the theory, including states coming from the twisted sectors, and capture some of the interactions fixed by gauge invariance. We also discuss the spectrum of the bulk theory and explain how linearization around $AdS_3$ gives rise to the expected set of decoupled wave equations. Our results can be generalized to describe bulk duals of other large-$N$ symmetric orbifolds.

Mother and child

description: This study examined the relationship between maternal education, the home environment, educational expectations and children’s math skills. The aim of this research was to determine how well these measures individually and collectively explained the variation in children’s mathematical achievement at the start of kindergarten. This analysis was done within the context of the unique biological mother-child relationship, how frequently they engaged with their children in shared activities at home, the warmth of their relationship with their children, their perspectives on parenting, and finally their aspirations for their children’s educational attainment. Relying on a large, nationally representative sample of 10,863 biological mothers and their children, this study found a persistent and moderate association between maternal education and children’s mathematical skills, even after adjusting for both the home environment and educational expectations measures, and several other select maternal, child, and family characteristics. The home environment, measured by maternal self-reports of the frequency of engagement in eight pre-selected activities and by maternal self-ratings of the warmth of the relationship with their children, was addressed using Principal Component Analysis. The findings in this area were mixed. A higher self-reported frequency of time spent playing games, talking about nature, playing with construction toys, and helping with arts and crafts was positively linked to children’s early math achievement. The frequency of shared book reading, storytelling, and working with numbers was negatively linked to children’s mathematical achievement. Both of these effect sizes were statistically significant, yet quite small. No relationship was found between maternal warmth and children’s mathematical skills or between parenting perspectives and children’s math achievement. The findings also demonstrated a small, positive association between maternal expectations and children’s mathematical achievement. Children whose mothers believed they would graduate from college or beyond had stronger math skills than those whose mothers expected them to experience some college. This finding was more pronounced among mothers from different cultural backgrounds. The continued significance of both the maternal education and maternal expectations effects helped to explain some of the variation in children’s math achievement and contributed to the important research aimed at reducing these gaps early in children’s formative education.
