description: Excitons in diluted magnetic semiconductors represent excellent probes for studying the magnetic properties of these materials. Various magneto-optical effects, which depend sensitively on the exchange interaction of the excitons with the localized spins of the magnetic ions can be used for probing. Here, we study core/shell CdSe/(Cd,Mn)S colloidal nanoplatelets hosting diluted magnetic semiconductor layers. The inclusion of the magnetic Mn$^{2+}$ ions is evidenced by three magneto-optical techniques using high magnetic fields up to 15 T: polarized photoluminescence, optically detected magnetic resonance, and spin-flip Raman scattering. In particular, information on the Mn$^{2+}$ concentration in the CdS shell layers can be obtained from the spin-lattice relaxation dynamics of the Mn$^{2+}$ spin system.
Conserving Gapless Mean-Field Theory for Bose-Einstein Condensates
Creators: name: Kita, Takafumi
Publisher: name: arXiv

Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: We formulate a conserving gapless mean-field theory for Bose-Einstein condensates on the basis of a Luttinger-Ward thermodynamic functional. It is applied to a weakly interacting uniform gas with density $n$ and s-wave scattering length $a$ to clarify its fundamental thermodynamic properties. It is found that the condensation here occurs as a first-order transition. The shift of the transition temperature $ΔT_c$ from the ideal-gas result $T_{0}$ is positive and given to the leading order by $ΔT_c = 2.33a n^{1/3}T_0$, in agreement with a couple of previous estimates. The theory is expected to form a new theoretical basis for trapped Bose-Einstein condensates at finite temperatures.

Subjects: subject: 620

description: Complex mechatronic products are usually decomposed into several sub-systems for their development. These sub-systems are developed in parallel or even independently based on their specifications and use cases. The application of model-based solution patterns is an effective way to comprehensively and efficiently describe the available knowledge about the sub-systems. This contribution proposes an approach to support the selection and application of model-based solution patterns. The approach, based on a metamodel for solution patterns using SysML, describes the process for selecting solution patterns and aligning requirements and constraints with the as-is properties of the sub-systems. Additionally, the approach supports the design of solution patterns taking into account special knowledge from the development of the sub-systems as well as the usage of the solution patterns in different systems and contexts. As an example, an application scenario of a specific load cell within a measurement system is explained.

description: We present a beyond-mean-field approach to predict the nature of organic polariton lasing, accounting for all relevant photon modes in a planar microcavity. Starting from a microscopic picture, we show how lasing can switch between polaritonic states resonant with the maximal gain, and those at the bottom of the polariton dispersion. We show how the population of non-lasing modes can be found, and by using two-time correlations, we show how the photoluminescence spectrum (of both lasing and non-lasing modes) evolves with pumping and coupling strength, confirming recent experimental work on the origin of blueshift for polariton lasing.

The targum (1953:Nov. 3 - 1953:Nov. 24)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1953

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

Subjects: subject: 620

description: Technical products are developed to meet the demands of stakeholders. Therefore, the product's functions and associated properties are important. Various influencing factors e.g., external disturbances can have an impact on the input flows of the products or its characteristics and thus on the functions. If this leads to deviations between the required and as-is functions, these deviations are called errors. It is therefore important to analyze errors in product development and implement measures to increase the robustness of the product. Model-Based Systems Engineering (MBSE) supports the development of complex systems. However, MBSE alone has limited ability to identify in-depth errors. This requires knowledge of possible errors from previous products in specific contexts. For this purpose, the method proposed in this paper facilitates identifying errors in the concept phase by combining MBSE approaches with reusable knowledge (i.e., knowledge graph). The approach is presented using an application example for a mobile robot.

description: We present a detailed spectroscopic investigation of a thermal $^{87}$Rb atomic vapour in a magnetic field of 1.5~T in the Voigt geometry. We fit experimental spectra for all Stokes parameters with our theoretical model \textit{ElecSus} and find very good quantitative agreement, with RMS errors of $\sim 1.5$\% in all cases. We extract the magnetic field strength and the angle between the polarisation of the light and the magnetic field from the atomic signal, and we measure the birefringence effects of the cell windows on the optical rotation signals. This allows us to carry out precise measurements at a high field strength and arbitrary geometries, allowing further development of possible areas of application for atomic magnetometers.

Making the classroom a healthy place : the development of affective competency in Aboriginal pedagogy
Creators: name: Brown, Francis Lee
Publisher: name: University of British Columbia
Year: 2009

description: This thesis explores the development of affective competency in Aboriginal pedagogy through the exploration of the Native Training Institute (NTI), an institute that functioned from 1980 to 1987 in Kamloops, British Columbia. Ten students, two administrators arid one elder were interviewed to explore how the processes of affective education were included in the NTI curriculum. The thesis develops a theory of educational transformation based on the educational principles developed at the Native Training Institute that posits a theory of affective development founded on Aboriginal knowledge, learning identity, values, competencies, ideals and vision. Four arguments for the inclusion of affective education in contemporary curriculum are presented. First, the Indigenous assertion that emotions and values are essential to the decolonization process and therefore necessary for Aboriginal success in the educational environment is defined. Second, the argument of modern European philosophy that affect is more essential to the process of learning than has been previously thought. Third, the recent developments in cognitive science that uphold the Aboriginal world view that thinking and feeling are not only connected but that emotion plays the major role in the functioning of mind and memory. Fourth, the comments of the students from the NTI that the affective aspect of the curriculum at the institute was essential to their learning.

All these compounds are found to show large magnetoresistance (with a negative sign) in the paramagnetic state at rather high temperatures with the magnitude peaking at respective magnetic ordering temperatures. There is a corresponding behavior in the magnetocaloric effect as inferred from the entropy derived from these data.

Subjects: subject: 620

description: Model Based Systems Engineering (MBSE) offers a systematic approach to address the challenges faced by industries in developing complex systems. However, the full implementation of MBSE Process, Methods, and Tools (PMT) in industry remains a challenge. This paper focuses on the implementation of the 3DEXPERIENCE MBSE toolchain by Dassault Systèmes Industrial Service (DSIS), introduces the typical challenges observed during the MBSE implementation process and categorizes them into five types. Based on industrial best practices and service experiences, the paper proposes multiple solution elements to overcome these challenges. These elements emphasize stakeholder support, establish an experience-based MBSE capability, enrich MBSE capabilities to solution bricks, create an implementation plan and validate through proof of concepts. The interdependency between solution elements allows efficient implementation and realization of short-term benefits. The paper concludes by discussing the value and applicability of the proposed solution elements, highlighting their potential for the industrial practice. The chapter closes with an outline of future steps to mature and advance the solution elements.

description: By law, US food aid relies on commodity procurement in the US. A powerful political coalition of US farm groups, shippers and relief agencies vigorously supports these in-kind food aid donation. As an alternative, local procurement of food aid, in Africa, has attracted growing interest because of its potential to reduce landed costs and speed delivery times. For this reason, many food aid donors, other than the US, have switched to local and regional procurement of food aid commodities. This paper reviews experience with local and regional food aid procurement in Zambia. The study focuses primarily on experience of the World Food Programme (WFP), the agency with the most extensive experience conducting local and regional procurement in Africa. WFP’s experience suggests that local or regional procurement of food aid offers significant savings, in both commodity costs and delivery times. On average, maize procured in Africa costs 30% to 50% less than white maize imported from the US and arrives 1 to 2 months faster than commodity imports from the US.

description: Quantum chaos imposes universal spectral signatures that govern the thermofield dynamics of a many-body system in isolation. The fidelity between the initial and time-evolving thermofield double states exhibits as a function of time a decay, dip, ramp and plateau. Sources of decoherence give rise to a nonunitary evolution and result in information loss. Energy dephasing gradually suppresses quantum noise fluctuations and the dip associated with spectral correlations. Decoherence further delays the appearance of the dip and shortens the span of the linear ramp associated with chaotic behavior. The interplay between signatures of quantum chaos and information loss is determined by the competition among the decoherence, dip and plateau characteristic times, as demoonstrated in the stochastic Sachdev-Ye-Kitaev model.

description: Along the development process of technical products, challenges arise repeatedly, which result from uncertainties, i.e., conscious, or unconscious gaps in knowledge or definitions. The causes often lie in the fact that empirical values represent the basis for many decisions, from the specification of tasks to the required organizational and control structures to the models and calculation tools used. Based on this knowledge, it is essential to continuously identify, evaluate and, if necessary, reduce the degree of uncertainty during the development of innovative products. This is intended to avoid potentially negative influences on the strategic goals of the magic triangle of project management (costs, time, and quality). This is exactly where the investigations started, using the example of an automotive supplier company. Completed projects are the starting point. A first focus is on the analysis of the effects of unclearly defined requirements and ambiguities in verification, validation, and end customer use. A second focus is the systematization, classification up to the provision of project-specific tools, which should facilitate the reduction of uncertainties already in early project phases.

description: Experiments observing the liquid surface in a vertically oscillating container have indicated that modeling the dynamics of such systems require maps that admit states at infinity. In this paper we investigate the bifurcations in such a map. We show that though such maps in general fall in the category of piecewise smooth maps, the mechanisms of bifurcations are quite different from those in other piecewise smooth maps. We obtain the conditions of occurrence of infinite states, and show that periodic orbits containing such states are superstable. We observe period-adding cascade in this system, and obtain the scaling law of the successive periodic windows.

description: It has been demonstrated in the recent years that nanomechanical mass spectrometry was well suited for the analysis of specific high mass species such as viruses. Still, the exclusive use of one-dimensional devices such as vibrating beams forces a trade-off between analysis time (related to capture area) and mass resolution (inversely proportional to device mass). Such devices also require complex readout schemes to simultaneously monitor multiple resonance modes, in particular when stiffness or shape come into play, which degrades mass resolution. These issues restrict nanomechanical MS to the analysis of species with specific properties. We report here the first demonstration of single-particle mass spectrometry with nano-optomechanical resonators fabricated with a Very Large Scale Integration process. The unique motion sensitivity of optomechanical techniques allows the use of resonators with new topologies. The device introduced here is designed to be impervious to particle position, stiffness or shape, opening the way to the analysis of large aspect ratio biological objects of great significance such as viruses with a tail or fibrils. Compared to top-down beam resonators with electrical read-out and state-of-the-art mass resolution, we show a three-fold improvement in capture area with no resolution degradation, despite the use of a single resonance mode. Short analysis time is in reach thanks to the sensitivity and bandwidth of optomechanical read-out and its compliance with telecom multiplexing techniques.

description: Product development means identifying the needs of different stakeholders, developing a product for them to the point where it is ready for production and use, and documenting it. To manage the complexity of product development, it is becoming increasingly digitalised. As virtual product development is a key area of industry, teaching in this area is an important component of a practice-oriented engineering curriculum. Engineering education constantly requires new teaching and learning formats. The trend is towards a systematic combination of digital teaching materials for self-organised individual and cooperative self-study on the one hand, and in-depth forms of classroom teaching tailored to the needs of students on the other - in short: hybrid forms of teaching and learning. Within the framework of an eTeach impulse project for a hybrid teaching and learning environment for virtual product development, important results have been developed, implemented and evaluated to achieve this goal.

description: Two Galactic isolated strong X-ray pulsars seem to be in the densest environments compared to other types of Galactic pulsar. X-ray pulsar J1846-0258 can be in an early phase of anomalous X-ray pulsars and soft gamma repeaters if its average braking index is ~1.8-2.0. X-ray pulsar J1811-1925 must have a very large average braking index (n~11) if this pulsar was formed by SN 386AD. This X-ray pulsar can be in an early phase of evolution of the radio pulsars located in the region P~50-150 ms and P~10$^{-14}-10^{-16}$ s/s of the P-P diagram. X-ray/radio pulsar J0540-69 seems to be evolving in the direction to the dim isolated thermal neutron star region on the P-P diagram. Possible progenitors of different types of neutron star are also discussed.

description: Given heavy dependence on rainfed maize production, Zambia must routinely cope with pronounced production and consumption volatility in their primary food staple. Typical policy responses include increased food aid flows, government commercial imports and stock releases, and tight controls on private sector trade. This paper examines recent experience in Zambia, using a simple economic model to assess the likely impact of maize production shocks on the domestic maize price and on staple food consumption under alternative policy regimes. In addition to an array of public policy instruments, the analysis evaluates the quantitative impact of two key private sector responses in moderating food consumption volatility— private cross-border maize trade and consumer substitution of an alternate food staple (cassava) for maize. The analysis suggests that, given a favorable policy environment, private imports and increased cassava consumption together could fill roughly two-thirds of the maize consumption shortfall facing vulnerable households during drought years.

This method is based on an FE data-based surrogate model and is intended to support the simulation-based product design process. To demonstrate their application and necessity, a case study on the design of eBike drive units is presented. For this purpose, the general requirements for the design of eBike drive units as well as the fundamentals of multiaxial fatigue analysis and surrogate modeling are outlined. In addition, a validation process of the surrogate model and its use for fatigue calculation is presented and discussed.

description: Infinite projected entangled pair states (iPEPS) have emerged as a powerful tool for studying interacting two-dimensional fermionic systems. In this review, we discuss the iPEPS construction and some basic properties of this tensor network (TN) ansatz. Special focus is put on (i) a gentle introduction of the diagrammatic TN representations forming the basis for deriving the complex numerical algorithm, and (ii) the technical advance of fully exploiting non-abelian symmetries for fermionic iPEPS treatments of multi-band lattice models. The exploitation of non-abelian symmetries substantially increases the performance of the algorithm, enabling the treatment of fermionic systems up to a bond dimension $D=24$ on a square lattice. A variety of complex two-dimensional (2D) models thus become numerically accessible. Here, we present first promising results for two types of multi-band Hubbard models, one with $2$ bands of spinful fermions of $\mathrm{SU}(2)_\mathrm{spin} \otimes \mathrm{SU}(2)_\mathrm{orb}$ symmetry, the other with $3$ flavors of spinless fermions of $\mathrm{SU}(3)_\mathrm{flavor}$ symmetry.

description: Spin and orbital magnetic moments of Re in AA'FeReO6 double perovskites (A,A' = Ba, Sr, Ca) have been directly probed employing XMCD spectroscopy at the Re L2,3-edges. A considerable orbital magnetic moment is observed in all the studied compounds despite octahedral coordination. Relative orbital to spin contribution per Re atom rises with lattice distortion from mL/mS = -0.28 to -0.34 for AA'=Ba2FeReO6 and Ca2FeReO6, respectively. A preliminary XMCD measurements at the Fe L2,3-edges reveals also a significant orbital moment of iron in Ca2FeReO6. The relation of the results to the magnetic properties of the compounds is discussed.

description: Testing a system for observability is of great practical relevance in technical applications. For linear systems, this problem was solved decades ago. The observability of nonlinear systems can be formally defined, but the actual verification is extremely difficult. For the subclass of poynomial systems, the observability can be decided in a finite number of calculation steps. In this paper, we provide an observability test for embedded polynomial systems. The observability test uses methods of algebraic geometry.

description: The Cassini spacecraft's last orbits directly sampled Saturn's thermosphere and revealed a much more chemically complex environment than previously believed. Observations from the Ion and Neutral Mass Spectrometer (INMS) aboard Cassini provided compositional measurements of this region and found an influx of material raining into Saturn's upper atmosphere from the rings. We present here an in-depth analysis of the CH$_4$, H$_2$O, and NH$_3$ signal from INMS and provide further evidence of external material entering Saturn's atmosphere from the rings. We use a new mass spectral deconvolution algorithm to determine the amount of each species observed in the spectrum and use these values to determine the influx and mass deposition rate for these species.

Year: 2025

description: Literature plays a crucial role in education by fostering critical thinking, cultural understanding, and creativity. However, traditional teaching methods often fail to accommodate the diverse learning styles of students, leading to disengagement and limited comprehension. This paper explores how literature instruction can be adapted to different learning styles visual, auditory, kinesthetic, and reading/writingthrough multimodal strategies to enhance student engagement and comprehension. Multimodal approaches integrate various instructional methods, such as digital storytelling, interactive e-books, and blended learning, to create a more inclusive and effective learning environment. Visual learners benefit from graphic novels, video adaptations, and mind maps, while auditory learners engage more with audiobooks, discussions, and oral presentations. Kinesthetic learners, who learn best through movement and hands-on activities, benefit from role-playing, dramatizations, and interactive projects. Meanwhile, reading/writing learners excel through journaling, analytical essays, and textual annotations. The study highlights the cognitive benefits of a multimodal approach, emphasizing that incorporating multiple sensory modalities enhances retention and comprehension. Additionally, differentiated instruction fosters an inclusive classroom environment, ensuring that all students, including those with learning disabilities, have access to meaningful learning experiences. A student-centered approach allows learners to engage with literature in ways that align with their strengths and preferences, increasing motivation and long-term interest in reading and analysis.
title: Digital Twin in Industrial Applications – How Model-Based Systems Engineering (MBSE) and Asset Administration Shell (AAS) complement each other

description: In the development, production and usage of cyber-physical systems, the number of stakeholders, involved interfaces and volatile environmental conditions is constantly rising. In addition, use cases require more consideration of the entire system life cycle. This significantly increases the administration effort and forms a barrier for the digital transformation of industrial companies. While model-based systems engineering (MBSE) addresses internal challenges within the product development and Asset Administration Shell (AAS) addresses vendor independent information exchange and interoperability, both approaches need to be coupled to address today’s challenges. In this publication typical tasks within product development are discussed: “search the right information”, “integrate the right information” and “provide the right information”. It is shown how they were approached today, without the alignment of MBSE and AAS, what technological concepts exists to address the challenges and how the tasks are realized by an alignment of MBSE and AAS.

description: Since the southern African food crisis of 2001/02, the ‘new-variant famine’ (NVF) hypothesis first proposed by de Waal and Whiteside (2003) has become an important part of the conventional wisdom surrounding the relationship between HIV/AIDS and food crises in the region. The NVF hypothesis suggests that HIV/AIDS is eroding agrarian livelihoods and exacerbating the effects of drought and other shocks on agrarian communities. These concepts have begun to shape the HIV/AIDS mitigation and food security policies and programs of governments and development agencies. To date, however, there is a dearth of empirical evidence to support the NVF hypothesis, and there have been no studies specifically designed to tests its predictions.
title: Can I play with madness : American missionaries in Iran during the 1960s and 1970s
Creators: name: Hopkins, Philip O
Publisher: name: University of St Andrews

description: This thesis studied the interaction of American Protestant missionaries with Iranians during the 1960s and 1970s. It focused on the missionary activities of four American Protestant groups: Presbyterians, Assemblies of God, International Missions, and Southern Baptists. It argued that American missionaries’ predisposition toward their own culture confused their message of the gospel and added to the negative perception of Christianity among Iranians. This bias was seen primarily in the American missionaries’ desire to modernise Iran through education and healthcare, and between the missionaries’ relationship with Iranian Christians. Iranian attitudes towards missionary involvement in these areas were investigated, as was the changing American missionary strategy from a traditional method where missionaries had final say on most matters related to American and Iranian Christian interaction to the beginnings of an indigenous system where a partnership developed between the missionary and the Iranian Christian. Freedoms that American missionaries were given under Mohammed Reza Shah to be overt in their evangelistic and discipleship activities, and details of the amount of Christian material propagated, were investigated. As missionaries eventually withdrew from Iran’s education and healthcare systems, more opportunities to be involved in Christian and Western activities were given to Iranian Christians. Finally, the state of the Iranian Church after 1979, when American missionaries were expelled from the country, was contrasted with the Iranian Church during the Pahlavi era. This section explained that while Iranian Christians were thankful for American missionaries, they were also resentful because Iranian Christians wanted Christianity to fit better within Iranian accepted norms and practices.

description: The algebraic dichotomy conjecture for Constraint Satisfaction Problems (CSPs) of reducts of (infinite) finitely bounded homogeneous structures states that such CSPs are polynomial-time tractable if the model-complete core of the template has a pseudo-Siggers polymorphism, and NP-complete otherwise. One of the important questions related to the dichotomy conjecture is whether, similarly to the case of finite structures, the condition of having a pseudo-Siggers polymorphism can be replaced by the condition of having polymorphisms satisfying a fixed set of identities of height 1, i.e., identities which do not contain any nesting of functional symbols. We provide a negative answer to this question by constructing for each non-trivial set of height 1 identities a structure within the range of the conjecture whose polymorphisms do not satisfy these identities, but whose CSP is tractable nevertheless. An equivalent formulation of the dichotomy conjecture characterizes tractability of the CSP via the local satisfaction of non-trivial height 1 identities by polymorphisms of the structure. We show that local satisfaction and global satisfaction of non-trivial height 1 identities differ for $ω$-categorical structures with less than doubly exponential orbit growth, thereby resolving one of the main open problems in the algebraic theory of such structures.

description: This paper investigates the relationship between income diversification and income change within Zambian smallholder households, and investigates what the constraints of income diversification are in this group. A panel data set of roughly 7000 smallholder farmer households interviewed in 2001 and 2004 is used. Different combinations of the four main income generating activities – farm income, agricultural wage work, non-agricultural wagework, and own-business income – are analyzed.

description: Cassava production has grown rapidly in Zambia since the early 1990’s. Available evidence suggests that volumes of traded cassava have been increasing roughly twice as fast as production. Yet this cassava production boom could stall unless commercial markets for it develop. To help accelerate commercial development of cassava and cassava-based products at the national level, Zambia’s Agricultural Consultative Forum (ACF) initiated an Acceleration of Cassava Utilization (ACU) Task Force, beginning in August 2005. At a regional level, efforts such as the Cassava Transformation in Southern Africa (CATISA) project aim to complement national efforts and help facilitate regional spillovers, so that new products, new technologies or new lessons can help to accelerate cassava-based commercial growth throughout the region. This paper aims to provide empirical content in support of both the ACU Task Force and CATISA activities.

description: The increasing complexity of technical solutions caused by constantly changing requirements and competitive situations, has led to the introduction of agile development processes in various domains in order to be able to react faster and more efficient to changes. This paper explores the integration of agile aspects into engineering education to prepare students for the corporate world. Two approaches, a single-stage and a two-stage approach, were implemented and evaluated in student projects at Technische Hochschule Ulm and Technische Universität Ilmenau. The findings reveal that both approaches effectively enhance students' competencies in agile product development. The observations highlight the value of iterative sprints, design thinking, peer learning, focused work, stakeholder involvement and the application of digital tools. Students exhibited increased confidence, independence, and creativity in their development projects. The integration of agile approaches in teaching methodologies proves beneficial in addressing the challenges posed by complex technical solutions and evolving requirements.

description: Engineering changes are often classified as critical and lead to high costs. The reason for this is the high system complexity. To deal with high complexity, MBSE can be used as an approach. However, in order to be able to operate model-based engineering change management, suitable approaches are required. The Advanced Engineering Change Impact Approach - AECIA presents a holistic methodology for model-based change management by supporting change request validity checking, change propagation and change impact analysis, and change information communication in an agile development environment. In this publication, the methodology is extended to include a procedure for checking the validity of change requests, applied to a real change case using a machine tool as an example, and initially evaluated.

description: The economic reforms in maize marketing and trade policies implemented during the 1990s have been highly controversial, and there remains a lack of solid empirical investigation on the impacts of these reforms on national food security, price stability and rural income growth. This study aims to provide a detailed evidence-based analysis of the impacts of maize marketing and trade policies on smallholder agricultural production growth, access to food by consumers, and other important national policy objectives. These insights from Zambia can hopefully move forward the continuing debate in the region on how maize marketing and trade policies should be structured in the future.
