description: Excess loop delay (ELD) in high speed continuous-time (CT) Delta-Sigma-Modulators (DSMs) imposes design challenges and limits the use of high resolution, e.g. successive-approximation-register (SAR) based internal quantizers, as usual compensation techniques like the use of a direct path around the quantizer come with increased swings and reduced maximum stable amplitude (MSA). In this paper, two bitwise ELD compensation approaches applicable to cascade-of-integrators with distributed feedback (CIFB) loop filters are proposed, which alleviate this problem for SAR and other multi-step quantizers by sequentially feeding bits into the feedback loop when they are available (MSB first, LSB last). Loop-filter equivalence for such bitwise ELD compensation is analytically derived. System-level simulations using Matlab & Simulink for exemplary 4-bit 2nd, 3rd and 4th-order modulators show 40% reduction of the last integrator output swing compared to the conventional direct path compensation. This potentially allows to avoid the swing, quantizer scaling and noise trade-offs due to ELD in state of the art designs.

description: Abstract When connecting a voltage-biased Josephson junction in series to several microwave cavities, a Cooper-pair current across the junction gives rise to a continuous emission of strongly correlated photons into the cavity modes. Tuning the bias voltage to the resonance where a single Cooper pair provides the energy to create an additional photon in each of the cavities, we demonstrate the entangling nature of these creation processes by simple witnesses in terms of experimentally accessible observables. To characterize the entanglement properties of the such created quantum states of light to the fullest possible extent, we then proceed to more elaborate entanglement criteria based on the knowledge of the full density matrix and provide a detailed study of bi- and multipartite entanglement. In particular, we illustrate how due to the relatively simple design of these circuits changes of experimental parameters allow one to access a wide variety of entangled states differing, e.g., in the number of entangled parties or the dimension of state space. Such devices, besides their promising potential to act as a highly versatile source of entangled quantum microwaves, may thus represent an excellent natural testbed for classification and quantification schemes developed in quantum information theory.

description: Pocket diary kept by Hector Langevin during a trip by rail and steamship via the United States to visit British Columbia. In 1871 as Minister of Public Works of Canada, Langevin was sent by the Federal Cabinet to visit British Columbia with the mission to acquire knowledge of the new province in relation to the Canadian Pacific Railway and possible location of its western terminus, and also to study the requirements of British Columbia for public works. Langevin's journey took him from central Canada to Chicago, then by the American Pacific Railway to San Francisco, where he embarked on the steamer Prince Alfred traveling to Victoria on Vancouver Island, and then to the mainland.

Whilst the micromaser has long been recognised as an important model for the dynamics of open quantum systems far from equilibrium, so-called Josephson-photonics devices are a recently developed form of superconducting quantum circuit in which the quantum transport of charges through a voltage-biased Josephson junction drives the production of photons in a microwave resonator.
title: Perceptions and Use of Inclusive Language in Spanish

Subjects: subject: Spanish
subject: Gender
subject: Inclusive language
subject: Lenguaje inclusivo

description: This thesis investigates the perceptions and use of gender-inclusive language in Spanish among Spanish speakers living in the United States. The term inclusive language encompasses a series of written and spoken strategies intended to provide more linguistic options apart from the traditional use of the generic masculine, with the ultimate goal of increasing the visibility and representation of people who identify as women and nonbinary within the Spanish language. These strategies include "doubling", or using both the masculine and feminine form (e.g., los profesores y las profesoras, instead of los profesores); replacing the terminal -o with a graphical symbol such as @, *, or x; replacing the terminal -o with -e to neutralize gender; and/or the use of collective nouns (e.g., el profesorado) to replace the use of the generic masculine form. Extant literature about inclusive language in Spanish often analyzes the dynamics of the debate between language academies and activists, however the opinions and uses of day-to-day Spanish speakers are just beginning to be analyzed. Using survey and interview data, this thesis intends add to the growing body of literature about inclusive language, providing insight into current perceptions and uses of inclusive language in Spanish by speakers of diverse backgrounds.

description: The nonequilibrium dynamics of charges along one-dimensional tight-binding lattices subject to a vibronic background is analyzed in the two-particle sector of a dissipative Hubbard model. The role of symmetries for distinguishable fermions with opposite spins and for indistinguishable ones with polarized spins is revealed and is shown to cause transfer dynamics with non-Boltzmann types of asymptotic distributions. Explicit results are obtained within an improved path integral Monte Carlo approach and are compared against an approximate description in terms of rate equations.

description: Charge transfer dynamics is studied in a ratchet-type molecular wire subject to finite frequency driving. Numerically exact data are obtained within the path integral Monte Carlo approach over the full transient time regime until a stationary net population imbalance has been established. This allows for a quantitative comparison with the master equation approaches and, in particular, underlines the usefulness of these rate models.

description: Agricultural index insurance seeks to protect producers against negative shocks that are common across a prespecified area, i.e., an index insurance zone. Often, administrative boundaries are used to delineate such index insurance zones. However, administrative boundaries may not reflect relevant variations in yield over space, which can be costly for policyholders as well as the public, especially since agricultural insurance is often heavily subsidized. Increased availability of finely resolved geospatial data on agronomic conditions coupled with machine learning approaches to identify similarities promises the ability to reduce losses associated with index insurance by identifying more homogeneous zones. In this work, we examine the changes in welfare impacts of a hypothetical area-yield index insurance when redrawing zone boundaries on the basis of relevant observed agronomic conditions. Drawing upon crop cut data from over 10,000 maize fields in Kenya from 2016-2020 combined with satellite-based estimates of agronomic conditions, we examine the changes in expected utility to assess the value of data-driven and administrative insurance zones. When keeping the number of insurance zones equal to the number of administrative zones, we find that data-driven zones may offer only slightly higher risk reduction value than administrative zones. If no set number of zones are prespecified, the data-driven approach offers a flexible approach to identify an optimal number of zones that balances costs and performance. This approach can help inform program design as well as impact evaluations, as it further sheds light on trade-offs between the costs of ground sampling and zone size that can inform how to design and evaluate new programs in resource-constrained environments for maximum impact.

description: While supramolecular hosts capable of binding and transporting anions and ion pairs are now widely available, self-assembled architectures are still rare, even though they offer an inherent mechanism for the release of the guest ion(s). In this work, we report the dynamic covalent self-assembly of tripodal, urea-based anion cryptates that are held together by two orthoester bridgeheads. These hosts exhibit affinity for anions such as Cl−, Br− or I− in the moderate range that is typically advantageous for applications in membrane transport. In unprecedented experiments, we were able to dissociate the Cs⋅Cl ion pair by simultaneously assembling suitably sized orthoester hosts around the Cs+ and the Cl− ion.

description: Abstract Heat transport in open quantum systems is particularly susceptible to the modeling of system–reservoir interactions. It thus requires us to consistently treat the coupling between a quantum system and its environment. While perturbative approaches are successfully used in fields like quantum optics and quantum information, they reveal deficiencies—typically in the context of thermodynamics, when it is essential to respect additional criteria such as fluctuation-dissipation theorems. We use a non-perturbative approach for quantum dissipative dynamics based on a stochastic Liouville–von Neumann equation to provide a very general and extremely efficient formalism for heat currents and their correlations in open harmonic chains. Specific results are derived not only for first- but also for second-order moments, which requires us to account for both real and imaginary parts of bath–bath correlation functions. Spatiotemporal patterns are compared with weak coupling calculations. The regime of stronger system–reservoir couplings gives rise to an intimate interplay between reservoir fluctuations and heat transfer far from equilibrium.

description: 20 years ago, we described a human cell strain derived from subcutaneous adipose tissue of an infant supposed to have Simpson-Golabi-Behmel Syndrome (SGBS), thus called “SGBS cells”. Since then, these cells have emerged as the most commonly used cell model for human adipogenesis and human adipocyte biology. Although these adipocyte derived stem cells have not been genetically manipulated for transformation or immortalization, SGBS cells retain their capacity to proliferate and to differentiate into adipocytes for more than 50 population doublings, providing an almost unlimited source of human adipocyte progenitor cells. Original data obtained with SGBS cells led to more than 200 peer reviewed publications comprising investigations on adipogenesis and browning, insulin sensitivity, inflammatory response, adipokine production, as well as co-culture models and cell-cell communication. In this article, we provide an update on the characterization of SGBS cells, present basic methods for their application and summarize results of a systematic literature search on original data obtained with this cell strain.

description: In this thesis, we investigate the relationship between employee retention and workplace climate. Our investigation is based on the Federal Employee Viewpoint Survey (FEVS) conducted annually by the U.S Office of Personnel Management. We arrange employees into cohorts and summarize their responses using three methods from the literature on big data and high-dimensional statistics: Manhattan Plots, Elastic-Net with Stability Selection, and Principal Component Analysis. We find that employee retention is best explained by how respondents answer three questions: “I know what is expected of me on the job,” “When needed I am willing to put in the extra effort to get a job done,” and “My workload is reasonable.” However, respondent answers are highly correlated, with the first principal component explaining nearly two-thirds of the overall variation. Moreover, this variable explains a significant portion of employee retention.

description: Regulation of cellular catabolic metabolism in immune cells has recently become a major concept for resolution of inflammation. Nuclear receptors (NRs), including peroxisome proliferator activator receptors, 1,25-dihydroxyvitamin D (3) receptor, liver X receptors, glucocorticoid receptors, oestrogen-related receptor α and nuclear receptor 4A1, have been identified as major modulators of inflammation, affecting innate immune cells, such as macrophages. Evidence emerges on how NRs regulate cellular metabolism in macrophages during inflammatory processes and contribute to the resolution of inflammation. This could have new implications for our understanding of how NRs shape immune responses and inform anti-inflammatory drug design. This review will highlight the recent developments about NRs and their role in cellular metabolism in macrophages.

description: he growth of adipose tissue and its vasculature are tightly associated. Angiogenic factors have been linked to obesity, yet little is known about their expression during early childhood. To identify associations of angiogenic factors with characteristics on individual and tissue level, subcutaneous white adipose tissue samples were taken from 45 children aged 0–9 years undergoing elective surgery. We measured the expression of vascular endothelial growth factor A (VEFGA), fibroblast growth factor 1 and 2 (FGF1, FGF2), angiopoietin 1 and 2 (ANGPT1, ANGPT2), TEK receptor tyrosine kinase (TEK), and von Willebrand factor (VWF). In addition, we determined the mean adipocyte size in histologic tissue sections. We found positive correlations of age with FGF1 and FGF2 and a negative correlation with ANGPT2, with pronounced differences in the first two years of life. FGF1, FGF2, and ANGPT1 correlated positively with adipocyte size. Furthermore, we identified a correlation of ANGPT1 and TEK with body mass index-standard deviation score (BMI-SDS), a measure to define childhood obesity. Except for ANGPT2, all angiogenic factors correlated positively with the endothelial marker VWF. In sum, our findings suggest that differences related to BMI-SDS begin early in childhood, and the analyzed angiogenic factors possess distinct roles in adipose tissue biology.

description: In recent years, certain advocacy campaigns launched in the midst of on going peace processes by mainstream Human Rights Non-Governmental Organizations (HR NGOs) has created much controversy. HR NGOs that base their advocacy efforts exclusively on international legal frameworks such as the Universal Declaration of Human Rights (UDHR) and legal instruments such as the International Criminal Court (ICC) have been accused by some groups and individuals in protracted conflict situations of slowing down or stopping peace negotiations ignoring the urgency of local populations for resolutions. This thesis examined this controversy in depth through mainstream HR NGO advocacy campaigns in three active conflict zones: Northern Uganda, Darfur region of Sudan and North-East Sri Lanka. Findings of this research reveal the limitations of the current mainstream NGO approach to human rights advocacy in active conflict zones and suggest a more comprehensive “Do No Harm” approach that has the potential of addressing the many complexities of protracted social conflicts with minimal harm to victims.

description: Brown adipose tissue (BAT) has been considered beneficial for metabolic health by participating in the regulation of glucose homoeostasis. The browning factors that improve glucose uptake beyond normal levels are still unknown but glucose uptake is not affected in UCP1 knockout mice. Here, we demonstrate in human white adipocytes that basal/resting glucose uptake is improved by solely elevating UCP1 protein levels. Generating human white Simpson-Golabi-Behmel syndrome (SGBS) adipocytes with a stable knockout and overexpression of UCP1, we discovered that UCP1 overexpressing adipocytes significantly improve glucose uptake by 40%. Mechanistically, this is caused by higher glycolytic flux, seen as increased oxygen consumption, extracellular acidification and lactate secretion rates. The improvements in glucose handling are comparable to white-to-brown transitions, as judged by, for the first time, directly comparing in vitro differentiated mouse brown vs white adipocytes. Although no adipogenic, metabolic and mitochondrial gene expressions were significantly altered in SGBS cells, pharmacological inhibition of GLUT1 completely abrogated differences between UCP1+ and control cells, thereby uncovering GLUT1-mediated uptake as permissive gatekeeper. Collectively, our data demonstrate that elevating UCP1 levels is sufficient to improve human white adipocytes as a glucose sink without adverse cellular effects, thus not requiring the adrenergic controlled, complex network of browning which usually hampers translational efforts.

description: Deciphering the non-coding regions of the eukaryotic genes continues to be an important transdisciplinary area spanning bioinformatics and experimental biology fields. Upstream of a eukaryotic gene there is a region of regulatory DNA sequences, which serve as genetic switches for modulating its expression. Various computational methods have been implemented to locate specific functionally important genomic elements. Nonetheless, accurately detecting promoters, transcription start sites (TSS), and transcription factor binding sites (TFBS) is a conundrum as even the finest and most sophisticated computational tools produce a significant amount of false positive and false negative predictions. In this study, our objective was to accurately classify regulatory regions in several eukaryotic species and elucidate their roles. Information of several transcription factors (TFs) of rice (O. sativa), their corresponding binding sites and the distribution of these sites near TSSs of rice genome were obtained from (Triska, et al., 2017), (Tatarinova, et al., 2016). For each transcription factor, we determined its orthologues in other species and compared their binding sites to those of O. sativa transcription factors. After mapping the identified TFs to non-plant eukaryote genomes, we discovered their putative binding sites in non-plant eukaryote species, and analyzed the distribution of distances between corresponding TFBS and TSS. We have shown that the genome distributions of orthologous TFBSs in rice (O. sativa), fruit fly (D. melanogaster), two species of rodents (M. musculus and R. norvegicus), as well as humans (H. sapiens) share similar characteristics, thus, proving a conservative nature of TF-TFBS interactions at a genomic scale.

description: Macrophages are key cells after tissue damage since they mediate both acute inflammatory phase and regenerative inflammation by shifting from pro-inflammatory to restorative cells. Glucocorticoids (GCs) are the most potent anti-inflammatory hormone in clinical use, still their actions on macrophages are not fully understood. We show that the metabolic sensor AMP-activated protein kinase (AMPK) is required for GCs to induce restorative macrophages. GC Dexamethasone activates AMPK in macrophages and GC receptor (GR) phosphorylation is decreased in AMPK-deficient macrophages. Loss of AMPK in macrophages abrogates the GC-induced acquisition of their repair phenotype and impairs GC-induced resolution of inflammation in vivo during post-injury muscle regeneration and acute lung injury. Mechanistically, two categories of genes are impacted by GC treatment in macrophages. Firstly, canonical cytokine regulation by GCs is not affected by AMPK loss. Secondly, AMPK-dependent GC-induced genes required for the phenotypic transition of macrophages are co-regulated by the transcription factor FOXO3, an AMPK substrate. Thus, beyond cytokine regulation, GR requires AMPK-FOXO3 for immunomodulatory actions in macrophages, linking their metabolic status to transcriptional control in regenerative inflammation.

While the importance of MAT for bone health has long been recognized, its complex role in hematopoiesis has only recently gained attention. In this review article we summarize recent conceptual advances in the field of MAT research and how these developments impact our understanding of MAT regulation of hematopoiesis. Elucidating routes of interaction and regulation between MAT and cells of the hematopoietic system are essential to pinpoint vulnerable processes resulting in malignant transformation. The concept of white adipose tissue contributing to cancer development and progression on the cellular, metabolic, and systemic level is generally accepted. The role of MAT in malignant hematopoiesis, however, is controversial. MAT is very sensitive to changes in the patient’s metabolic status hampering a clear definition of its role in different clinical situations. Here, we discuss future directions for leukemia research in the context of metabolism-induced modifications of MAT and other adipose tissues and how this might impact on leukemia cell survival, proliferation, and antileukemic therapy.

description: Continuous casting is a critical process in steel manufacturing, which yields superior quality, and efficiency compared to conventional ingot casting. However, challenges such as macro-segregation, fluid flow instabilities, and inclusion entrapment persist, directly affecting the quality and uniformity of the final steel product. This thesis presents a comprehensive computational investigation into the coupled phenomena of fluid flow and chemical segregation during continuous casting, utilizing advanced Computational Fluid Dynamics (CFD) techniques. A robust Multiphysics CFD framework was developed to model solidification, solute transport, and argon injection across full-scale slab geometries. The solidification process was simulated using the enthalpy-porosity technique, capturing the progression of mushy zones and the growth of shell thickness under realistic thermal and flow boundary conditions. A carbon segregation model, based on solute partitioning and mass transport equations, was integrated to analyze the redistribution of carbon during solidification. Parametric studies involving three different steel grades, superheat variations, and casting speeds were conducted to assess their influence on carbon segregation intensity and shell growth behavior. Additionally, the study incorporated a two-phase Euler–Lagrange model to simulate argon gas injection and its impact on mold flow dynamics. The role of bubble size and distribution was investigated in relation to flow turbulence, inclusion removal efficiency, and meniscus stability. The influence of mold geometry, particularly in thin-slab casting configurations, was also examined to understand the effects of mold width and casting speed on jet impingement, recirculation zones, and breakout risks. The simulation results revealed key insights into the mechanisms of macro-segregation, the effects of steel composition on segregation severity, and the physics of gas-liquid interactions in the mold. This work provides valuable guidelines for optimizing casting conditions to reduce centerline segregation, improve flow uniformity, and minimize surface defects. The findings offer a strong foundation for future CFD-based process control in continuous casting and contribute to the advancement of clean and high-performance steel production.

description: Smallholders play an important role as producers of cash-crops in developing countries and are often responsible for land clearing and agricultural expansion into pristine environments where productivity is low. Closing yield-gaps of smallholders to industrial plantations as well as diversifying production systems has been identified as a mean to prevent further environmental degradation. At the same time, developing and emerging economies are beginning to struggle with an ageing farmer population, potentially hindering advances in land productivity. In Indonesia, increased income from oil palm cultivation has led to rapid educational attainments within one generation. While this opens job opportunities for children of oil palm smallholders, it inhibits farm succession and thus contributes to ageing among smallholders. Using primary data from a random sample of 417 oil palm smallholders in Indonesia, we investigate trends of farm succession and test, how these moderate possible effects of ageing on plantation investments and outcomes. Our results suggest, that older farmers are associated with lower productivity levels generally and are less likely to replant mature plots. These trends are moderated by succession plans of households. Succession generally moderates negative effects on productivity – indifferent of the successor’s involvement. Households with a successor are generally more likely to replant. We argue that these results hint towards strategic decision- making in ageing smallholders and that observed trends of lower productivity and technology adoption in ageing farmer populations are likely a mix of both decreasing ability and strategic decisions by the farmer.

description: Quantizer (QTZ) latency and therefore excess loop delay (ELD) compensation techniques in wideband continuous-time (CT) Delta-Sigma-Modulators (DSMs) are particularly important due to stringent timing requirements. To relax timing constraints, a bitwise ELD compensation technique for internal multi-step QTZs has been introduced in prior art, which realizes feedback of individual bits in order to relax conversion time and loop filter output swings. This paper aims to analyze the impact of loop filter integrator nonidealities, most prominently finite amplifier gain-bandwidth product (GBW), when bitwise feedback is applied. The bitwise concept and possible configurations are reviewed and extended to a 3rd-order modulator. System-level simulations using Matlab/Simulink in presence of finite and varying GBW show that harmonic distortion is generated due to coefficient mismatch across the individual bits. The less bitwise feedback paths are applied, the more robust the technique becomes against these nonidealities, which makes bitwise feedback around the last integrator the most beneficial approach, while an integrator output swing reduction of −46% can be achieved compared to compensation in the QTZ.

description: Teachers' collaboration, from sharing support to pedagogy, influences school climate on a classroom and school level. Collaboration draws on the unique ideas that come from varied backgrounds and experiences within and outside of the school setting. Studies analyzing the relationship between teacher collaboration and school climate have not addressed the inclusion of students' backgrounds and experiences. This study investigates how diversity-related teaching practices may enhance the relationship between teacher collaboration and school climate. Using the 2018 Teaching and Learning Survey (TALIS), I focus on middle school teachers in the United States. I found that diversity practices and teacher collaboration each have a significant relationship with school climate, but there was no statistical evidence for the influence of diversity practices on the relationship between teacher collaboration and school climate. To provide actionable steps inspired by the research, I include brief recommendations for educators to develop their teaching based on the values of collaboration and diversity.
