description: In the context of a canonical quantization of general relativity, one can deform the loop gravity phase space on a graph by replacing the T*SU(2) phase space attached to each edge by SL(2,C) seen as a phase space. This deformation is supposed to encode the presence of a non-zero cosmological constant. Here we show how to parametrize this phase space in terms of spinor variables, thus obtaining deformed spinor networks for loop gravity, with a deformed action of the gauge group SU(2) at the vertices. These are to be formally interpreted as the generalization of loop gravity twisted geometries to a hyperbolic curvature.

description: This letter proposes a novel single-fingered reconfigurable robotic gripper for grasping objects in narrow working spaces. The finger of the developed gripper realizes two configurations, namely, the insertion and grasping modes, using only a single motor. In the insertion mode, the finger assumes a thin shape such that it can insert its tip into a narrow space. The grasping mode of the finger is activated through a folding mechanism. Mode switching can be achieved in two ways: switching the mode actively by a motor, or combining passive rotation of the fingertip through contact with the support surface and active motorized construction of the claw. The latter approach is effective when it is unclear how much finger insertion is required for a specific task. The structure provides a simple control scheme. The performance of the proposed robotic gripper design and control methodology was experimentally evaluated. The minimum width of the insertion space required to grasp an object is 4 mm (1 mm, when using a strategy).

description: We use observational properties of galaxies accumulated in the Updated Nearby Galaxy Catalog to derive a dark matter mass of luminous galaxies via motions of their companions. The data on orbital-to-stellar mass ratio are presented for 15 luminous galaxies situated within 11 Mpc from us: the Milky Way, M31, M81, NGC5128, IC342, NGC253, NGC4736, NGC5236, NGC6946, M101, NGC4258, NGC4594, NGC3115, NGC3627 and NGC3368, as well as for a composit suite around other nearby galaxies of moderate and low luminosity. The typical ratio for them is M_{orb}/M* = 31, corresponding to the mean local density of matter Omega_m = 0.09, i.e 1/3 of the global cosmic density. This quantity seems to be rather an upper limit of dark matter density, since the peripheric population of the suites may suffer from the presence of fictitious unbound members. We notice that the Milky Way and M31 haloes have lower dimensions and lower stellar masses than those of other 13 nearby luminous galaxies. However, the dark-to-stellar mass ratio for both the Milky Way and M31 is the typical one for other neighboring luminous galaxies. The distortion in the Hubble flow, observed around the Local Group and five other neighboring groups yields their total masses within the radius of zero velocity surface,R_0, which are slightly lower than the orbital and virial values. This difference may be due to the effect of dark energy, producing a kind of "mass defect" within R_0.

description: The Vibe Dance Video Set is a collection of eight video clips, each featuring a 3-minute dance performance that communicates the shared emotional atmosphere experienced within workgroups. Drawing from the group mood typology developed by Alev Sonmez, Pieter Desmet, and Natalia Romero Herrera (2022a), this video set explores the embodied representation of eight distinct group moods through artistic human movement. These group moods—Chill Flow, Fiery, Fuzzy, Creative, Tense, Confrontational, Slack, and Safe Haven—are described in the accompanying Eight Group Vibes booklet (Sönmez et al., 2022b).

The videos are produced by a team of professional artists, including choreographers, dancers, and specialists in music, filming, costumes, make-up, and set design (Sönmez, Desmet & Romero Herrera, 2021). Each video showcases five dancers performing a choreography designed to express a particular group mood. The choreographies incorporate bodily expressions combined with symbolic movements to communicate metaphors. The primary distinction between group moods is achieved through movement and is further supported by music.

The Vibe Dance Video Set was developed as part of a PhD project to communicate group moods in a comprehensive, relatable, and distinct way, and was used to support the embodied exploration of these moods in a workshop study (Sönmez, 2024). The video set can help group members reflect on, recognize, and discuss issues related to emotional dynamics within their workgroups. In the field of design, the videos can assist designers in empathizing with different group experiences and inspire the development of products, services, and interventions to foster beneficial group moods.

description: Collections of observed data from the Earth's atmosphere and, mainly, aerosol and trace gas data with the subsequent information produced are essential for the analysis and prediction of natural processes. After defining a data quality framework and metric conventions to handle data efficiently, a data portal is required for its publication and distribution of data so that it can be free and available in a web platform with Data Distribution Services. Despite the diversity and amount of data generated, there is an absence of web platforms in the Brazilian context that gather such data, making integration and access to data more difficult, as well as obtaining intelligence from this collection. Thus, we propose essential requirements for the development of a Data Portal, in such a way that it can achieve Big Data processing, human interaction and download-oriented approaches. To achieve the project objective, a requirements analysis was carried out using software engineering methodologies from the Atmospheric Radiation Measurement (ARM: www.arm.gov) platform and the FAIR principles for managing and administering scientific data. ARM provides a set of tools that help users to catalog, publish and analyse atmospheric data. The data portal’s functional requirements perform a wide variety of tasks, such as metadata management, data discovery, data citations, quality reports, and data access via the web. These tasks are considered as data recovery tools and FAIR tools. This paper specifies the requirements for a data portal for the atmospheric science community in Brazil.
Synthesizing Exoplanet Demographics from Radial Velocity and Microlensing Surveys, I: Methodology

description: Motivated by the order-of-magnitude difference in the frequency of giant planets orbiting M dwarfs inferred by microlensing and radial velocity (RV) surveys, we present a method for comparing the statistical constraints on exoplanet demographics inferred from these methods. We first derive the mapping from the observable parameters of a microlensing-detected planet to those of an analogous planet orbiting an RV-monitored star. Using this mapping, we predict the distribution of RV observables for the planet population inferred from microlensing surveys, taking care to adopt reasonable priors for, and properly marginalize over, the unknown physical parameters of microlensing-detected systems. Finally, we use simple estimates of the detection limits for a fiducial RV survey to predict the number and properties of analogs of the microlensing planet population such an RV survey should detect. We find that RV and microlensing surveys have some overlap, specifically for super-Jupiter mass planets ($m_p \gtrsim 1~M_{\rm Jup}$) with periods between $\sim 3-10~$years. However, the steeply falling planetary mass function inferred from microlensing implies that, in this region of overlap, RV surveys should infer a much smaller frequency than the overall giant planet frequency ($m_p\gtrsim 0.1~M_{\rm Jup}$) inferred by microlensing. Our analysis demonstrates that it is possible to statistically compare and synthesize data sets from multiple exoplanet detection techniques in order to infer exoplanet demographics over wider regions of parameter space than are accessible to individual methods. In a companion paper, we apply our methodology to several representative microlensing and RV surveys to derive the frequency of planets around M dwarfs with orbits of $\lesssim 30~$years.

description: Multiferroics with coupling between ferroelectricity and magnetism have been pursued for decades. However, their magnetoelectric performances remain limited due to the common trade-off between ferroelectricity and magnetism. Here, a family of nitride perovskites is proposed as multiferroics with prominent physical properties and nontrivial mechanisms. Taking GdWN$_3$ as a prototype, our first-principles calculations found that its perovskite phases own large polarizations (e.g. $111.3$ $μ$C/cm$^2$ for the $R3c$ phase) and a magnetic moment $7$ $μ_{\rm B}$/Gd$^{3+}$. More interestingly, its ferroelectric origin is multiple, with significant contributions from both Gd$^{3+}$ and W$^{6+}$ ions, different from its sister member LaWN$_3$ in which the ferroelectricity almost arises from W$^{6+}$ ions only. With decreasing size of rare earth ions, the A site ions would contribute more and more to the ferroelectric instability. Considering that small rare earth ions can be primary origins of both proper ferroelectricity and magnetism in nitride perovskites, our work provides a route to pursuit more multiferroics with unconventional mechanisms and optimal performances.

description: This presentation shows a longitudinal assessment of economic inequality and residential segregation of all Dutch urban areas between 2003 and 2021. Using microdata covering the entire population of the country, we differentiate between the segregation of poverty and the segregation of affluence by computing indicators for every percentile of the income distribution. Calculations also distinguish between net and gross income to evaluate the impact of social transfers and taxation. Although results show a general increase in the levels of inequality, there is considerable variance on its evolution across the country and segregation remains relatively stable. In addition, our findings confirm that the rich are usually more spatially clustered than the poor, but the latter is becoming increasingly segregated while the former is not. Notably, whereas taxation and social transfers reduce income inequality, they also paradoxically exacerbate segregation.

description: Processing magnetocaloric materials into magnetic refrigerants with appropriate shapes is essential for the development of magnetic refrigeration systems. In this context, the impact of processing on the physical properties of magnetocaloric materials is one of the important issues. Here, we investigate the crystallographic, magnetic, and magnetocaloric properties of gas-atomized particles of the intermetallic compound ErCo$_{2}$, a giant magnetocaloric material for low-temperature applications. The results demonstrate that the physical properties of ErCo$_{2}$ are significantly changed by atomization and subsequent thermal annealing. In the as-atomized particles, the magnetic transition temperature increases from 34 to 56 K and the phase transition changes from first order to second order. The thermal annealing shifts the transition temperature back to the original one and restores the first-order phase transition characteristic. The changes in magnetic properties are closely related to those in crystallographic properties, suggesting the importance of the magneto-structural coupling. The magnetic entropy change $-ΔS_{M}$ of the particles can be tuned in size, shape, and peak temperature depending on the annealing conditions. The peak value of $-ΔS_{M}$ varies in the range of 9--33 J kg$^{-1}$ K$^{-1}$ for a magnetic field change of 0--5 T. All the ErCo$_{2}$ atomized particles have magnetocaloric properties comparable or superior to other promising candidates for low-temperature magnetic refrigerants.

description: According to the current experimental data, the Higgs vacuum appears to be metastable due to the development of a second lower ground state in its potential. Consequently, vacuum decay would induce the nucleation of true vacuum bubbles with catastrophic consequences for our Universe and therefore we are motivated to study possible stabilising mechanisms in the early universe. In our latest investigation (2207.00696), we studied the electroweak metastability in the context of the observationally favoured model of Starobinsky inflation. Following the motivation and techniques from our first study (2011.037633), we obtained constraints on the Higgs curvature coupling $ξ$, while embedding the SM on the modified gravity scenario $R+R^2$, which introduces Starobinsky inflation naturally. This had significant repercussions for the effective Higgs potential in the form of additional negative terms that destabilize the false vacuum. Another important aspect lay in the definition for the end of inflation, as bubble nucleation is most prominent during its very last moments. Our results dictated that these stronger lower $ξ$-bounds are very sensitive to the final moments of inflation, where spacetime deviates increasingly from de Sitter.

description: Green dock beetles Gastrophysa viridula exhibit sexual dimorphism in tarsal attachment setae: females have only pointed, lanceolate and spatula-like setae, while males additionally possess discoidal ones. The sexual dimorphism is likely attributed to the necessity of male discoidal setae to adhere to the smooth back of the female during copulation. We aimed to understand its possible mechanism of attachment with G. viridula. Pull-off forces of both females and males were measured on (i) alive females, (ii) dead and dried females, and (iii) resin replicas of fresh females. The attachment ability tended to increase on dead and replicated female surfaces in both sexes, which indicates that the epicuticular grease layer on the integument of alive intact beetles decreases the attachment. This tendency was prominent in females. The present study clearly showed that in G. viridula discoidal setae enable the males to adhere stronger to female surfaces. The divergent performance found between the sexes differing in their setal composition is likely caused by the stiffness difference between the setae types and by the specific shape of the setal tips. A peculiar reproductive biology in G. viridula is likely attributed to this remarkable divergence of labour in their attachment pads between the sexes.
The Role of Chitinases and Fungal Siderophores in Salmonella enterica serovar Typhimurium Infection

description: Salmonella enterica serovar Typhimurium (S. Typhimurium) is one of the leading causes of food-borne illnesses worldwide. This thesis will cover two virulence mechanisms that S. Typhimurium exploits to promote gastrointestinal infection. The first mechanism that will be addressed is the expression of two chitinases by S. Typhimurium, STM0018 (chiA) and STM0233. The putative chitinase STM0233 has not been studied previously, and only limited data exists on ChiA. ChiA expression was detected in infection models and purified ChiA cleaved carbohydrate subunits present on mammalian surface glycoproteins, indicating a role during pathogenesis. Here, we demonstrate that that both chitinases facilitate epithelial cell adhesion and invasion in vitro. In a gastroenteritis mouse model, chitinase-deficient S. Typhimurium strains were also significantly attenuated in the invasion of small intestinal tissue. This reduced invasion resulted in significantly delayed S. Typhimurium dissemination to the spleen and the liver, but chitinases were not required for systemic survival. By analyzing N-linked surface glycans of small intestinal cells, we identified specific GlcNAc-containing glycans as potential extracellular targets of S. Typhimurium chitinases, potentially driving this adhesion and invasion defect. The second part of this thesis will describe the utilization of fungal siderophores by S. Typhimurium as a source of iron. During infection, the host limits the availability of micronutrients, like iron, to starve out pathogens. S. Typhimurium produces two iron-chelating molecules known as siderophores to acquire iron in this environment. In addition, S. Typhimurium express two receptors that are for specific for siderophores produced by fungi. Here, we show that these fungal siderophore receptors give S. Typhimurium the ability to utilize siderophores produced by commensal fungi and present in the diet. This provides S. Typhimurium a growth advantage in both in vitro cultures and in mouse models of infection. Overall, this thesis explores how the production of chitinases and the utilization of fungal siderophores promote S. Typhimurium infection.

description: The proposed LUXE experiment (Laser und XFEL Experiment) at DESY Hamburg, using the electron beam from the European XFEL, aims to probe QED in the non-perturbative regime created in collisions between high-intensity laser pulses and high-energy electron or photon beams. This setup also provides a unique opportunity to probe physics beyond the standard model. In this proceedings, we show that by leveraging the large photon flux generated at LUXE, one can probe axion-like-particles (ALPs) up to a mass of 350 MeV and with a photon coupling of $3\times{10}^{-6}\ \mathrm{GeV}^{-1}$. This reach is comparable to the background-free projection from NA62. In addition, we will discuss other probes of new physics such as ALPs-electron coupling.

description: An integral method for optimal modern supply chain management has been developed in this thesis. Influential factors of supply chain management have been classified as: model of product demand, synchronicity of working time, delivery time, minimal order quantity and implementation of backlogging procedures. Based on classified factors of inventory management, quantified factors of inventory management have been determined as: minimal number of deliveries, average size of delivery, average inventory level, coefficient of bullwhip effect, risk of delivery of backlogged products, lost sales, inventory management costs without discounts and inventory management costs with discounts. The new method of optimal inventory management in supply chains has been tested on 960 simulation experiments of inventory management system which confirmed all three hypotheses: (I) selection of supply chain inventory management strategy can have a significant influence on business performance indicators of the supply chain with potentially significant benefits when choosing an optimal strategy, (II) with the same average demand, increased demand uncertainty will increase the load on inventory management system and supply chain as a whole and (III) existing models, equations and algorithms for determining required inventory levels are not sufficiently accurate thereby, by using them companies risk reduced efficiency and increased supply chain costs related to inventory management.

description: The motion of colloids in the flow field of a viscous liquid is investigated. The small colloid size compare to the macroscopical scale of the flow allow to calculate their velocity relative to that of the liquid. If the inner colloid density is larger then the density of the liquid the flow field has the domains where the colloid velocity is close to the liquid velocity. But in the domains with a strong braking of the liquid velocity the colloids are accelerated relative to the liquid. This effect is used for the qualitative explanation of the drag reduction in the flow around macroscopical bodies and in the pipes.

description: In this paper, we introduce the notion of Cooperative Perception Error Models (coPEMs) towards achieving an effective and efficient integration of V2X solutions within a virtual test environment. We focus our analysis on the occlusion problem in the (onboard) perception of Autonomous Vehicles (AV), which can manifest as misdetection errors on the occluded objects. Cooperative perception (CP) solutions based on Vehicle-to-Everything (V2X) communications aim to avoid such issues by cooperatively leveraging additional points of view for the world around the AV. This approach usually requires many sensors, mainly cameras and LiDARs, to be deployed simultaneously in the environment either as part of the road infrastructure or on other traffic vehicles. However, implementing a large number of sensor models in a virtual simulation pipeline is often prohibitively computationally expensive. Therefore, in this paper, we rely on extending Perception Error Models (PEMs) to efficiently implement such cooperative perception solutions along with the errors and uncertainties associated with them. We demonstrate the approach by comparing the safety achievable by an AV challenged with a traffic scenario where occlusion is the primary cause of a potential collision.

Emergent quality issues in the supply of Chinese medicinal plants: A mixed methods investigation of their contemporary occurrence and historical persistence
Creators: name: Fitzgerald, Martin
Publisher: name: University of Westminster
Year: 2023

description: Quality issues that emerged centuries ago in Chinese medicinal plants (CMP) were investigated to explore why they still persist in an era of advanced analytical testing and extensive legislation so that a solution to improve CMP quality could be proposed. This is important for 85% of the world’s population who rely on medicinal plants (MP) for primary healthcare considering the adverse events, including fatalities that arise from such quality issues. CMP are the most prevalent medicinal plants globally. This investigation used mixed-methods, including 15 interviews with CMP expert key informants (KI), together with thematic analysis that identified the main CMP quality issues, why they persisted, and informed solutions. An unexplained case example, Eleutherococcus nodiflorus (EN), was analysed by collection of 106 samples of EN, its known toxic adulterant Periploca sepium (PS), and a related substitute, Eleutherococcus senticosus (ES), across mainland China, Taiwan and the UK. Authenticity of the samples was determined using High-performance thinlayer chromatography. Misidentification, adulteration, substitution and toxicity were the main CMP quality issues identified. Adulteration was found widespread globally with 57.4% EN found authentic, and 24.6% adulterated with cardiotoxic PS, mostly at markets and traditional pharmacies. The EN study further highlighted that the reason CMP quality issues persisted was due to the laboratory-bound nature of analytical methods and testing currently used that leave gaps in detection throughout much of the supply chain. CMP quality could be more effectively tested with patented analytical technology (PAT) and simpler field-based testing including indicator strip tests. Education highlighting the long-term economic value and communal benefit of delivering better quality CMP to consumers was recommended in favour of the financial motivation for actions that lead to the persistence of well-known and recurrent CMP quality issues.

description: We investigate the possibility of using the only known fundamental scalar, the Higgs, as an inflaton with minimal coupling to gravity. The peculiar appearance of a plateau or a false vacuum in the renormalised effective scalar potential suggests that the Higgs might drive inflation. For the case of a false vacuum we use an additional singlet scalar field, motivated by the strong CP problem, and its coupling to the Higgs to lift the barrier allowing for a graceful exit from inflation by mimicking hybrid inflation. We find that this scenario is incompatible with current measurements of the Higgs mass and the QCD coupling constant and conclude that the Higgs can only be the inflaton in more complicated scenarios.

description: В компонентной структуре прогресса человечества научно-технический составляющая определяет темпы, направления и содержание социального, духовного, культурного, правового, политического и экономического развития общества. Однако анализ хронологии научных, производственных и научно-технических революций не обнаружил их определенной последовательности и взаимообусловленности. Зато, согласно концепции «волн» развития человечества Е.Тоффлера (аграрной, промышленной, информационной), наблюдается их совпадение с появлением, развитием и упадком соответствующих типов обществ аграрного, индустриального и постиндустриального. Но при этом не идентифицируется движущая сила экономического и научно-технического развития, что компенсирует теория технологических укладов. Авторское исследование эволюции технологических укладов показал целесообразность их комплексной характеристики по совокупности приведенных в табл. 1 параметров.In the component structure of human progress, the scientific and technical component determines the pace, direction and content of social, spiritual, cultural, legal, political and economic development of society. However, the analysis of the chronology of scientific, industrial, and scientific-technical revolutions did not reveal their definite sequence and interdependence. But, according to the concept of "waves" of human development by E. Toffler (agricultural, industrial, informational), they coincide with the appearance, development and decline of the corresponding types of societies agricultural, industrial and post-industrial. However, the driving force of economic and scientific-technical development is not identified, which is compensated by the theory of technological structures. The author's study of the evolution of technological structures has shown the feasibility of their complex characteristics based on the set of parameters given in table 1.
title: "I Want to Know What I'm Looking at": Surveilling Gender as a Response to Cultural Anxieties in Halloween, Sleepaway Camp, and Scream

description: The purpose of this thesis is to investigate slasher films and how they use gendered tropes to respond to and perpetuate cultural anxieties. The methodology primarily uses textual analysis that includes close attention to content, context, and discourse. The study reveals structural patterns and problems that emerge within slasher films, specifically within the Final Girl trope and the behaviors that govern it. In surveilling the Final Girl’s gender performativity, it is apparent that abjection, or a gut reaction to something that exists between two distinct boundaries or categories, is provoked when the Final Girl crosses a socially established gender boundary. Her behaviors are closely monitored by herself and others. In reading the ways that these behaviors are exhibited through the body of the female lead, the thesis focuses on how panopticism, or bodily self-regulation in response to biopolitical power, is primarily expressed through these characters. Michel Foucault’s concept of internal surveillance proves to be a salient concept for examining the character development within slasher films, speaking to the power of self-regulation within gendered power relations. Cultural anxieties around gender are mobilized within American horror films, in ways that speak to both gender performativity and the desire to shore up gender categories as incontrovertible truths.

description: N-flation is a radiatively stable scenario for chaotic inflation in which the displacements of $N \gg 1$ axions with decay constants $f_1 \le \ldots \le f_N < M_P$ lead to a super-Planckian effective displacement equal to the Pythagorean sum $f_{Py}$ of the $f_i$. We show that mixing in the axion kinetic term generically leads to the phenomenon of kinetic alignment, allowing for effective displacements as large as $\sqrt{N} f_{N} \ge f_{Py}$, even if $f_1, \ldots, f_{N-1}$ are arbitrarily small. At the level of kinematics, the necessary alignment occurs with very high probability, because of eigenvector delocalization. We present conditions under which inflation can take place along an aligned direction. Our construction sharply reduces the challenge of realizing N-flation in string theory.

description: Строительная отрасль является неизвестной частью хозяйственного комплекса страны, индикатором роста или упадка экономики. Она тесно связана с другими областями, их развитием за счет строения производственных мощностей, складских и офисных помещений, логистических и инженерных сетей. Состояние и перспективы дальнейшей динамики в деятельности предприятий, относящихся к этой отрасли, является актуальным напряжением исследования в условиях трансформационных процессов, происходящих в России. Предприятия, относящиеся к области строительства, в 2016 году, согласно данным Росстата России, имеют долю 8,5% в общем объеме субъектов хозяйствования предприятий. Физические лица-предприниматели, работающие в этой сфере, составляют всего 1,5%. Однако их количество в 2019 году почти равно количеству предприятий.The construction industry is an unknown part of the economic complex of the country, an indicator of growth or decline of the economy. It is closely connected with other areas and their development through the construction of production facilities, warehouse and office premises, logistics and engineering networks. The state and prospects of further dynamics in the activities of enterprises belonging to this industry is an actual subject of research in the context of transformational processes taking place in Russia. In 2016, according to Rosstat data, enterprises related to construction have a share of 8.5% in the total volume of business entities enterprises. Individual entrepreneurs working in this field make up only 1.5%. However, their number in 2019 is almost equal to the number of enterprises.
