description: We study the Laplacian on Stenzel spaces (generalized deformed conifolds), which are tangent bundles of spheres endowed with Ricci flat metrics. The (2d-2)-dimensional Stenzel space has SO(d) symmetry and can be embedded in C^d through the equation \sum_{i = 1}^d {z_i^2} = ε^2. We discuss the Green's function with a source at a point on the S^{d-1} zero section of TS^{d-1}. Its calculation is complicated by mixing between different harmonics with the same SO(d) quantum numbers due to the explicit breaking by the ε-deformation of the U(1) symmetry that rotates z_i by a phase. A similar mixing affects the spectrum of normal modes of warped deformed conifolds that appear in gauge/gravity duality. We solve the mixing problem numerically to determine certain bound state spectra in various representations of SO(d) for the d=4 and d=5 examples.

description: Inspired by the allelopathetic effects of Xanthium orientale subsp. italicum (Moretti) Greuter, bioassay-guided isolation was employed to identify its antitumor constituents and clarify the chemical basis of its multitarget activity. Among four fractions of X.orientale extraction, TCM-fr and PE-fr were discovered to exhibit significant cytotoxicity aganist HepG two and A549 cells, which were further isolated by chromatographic methods to yield 16 compounds, including six active ones: xanthatin (1), xanthinosin (2), lupeol (6), oleanolic acid (9), betulinic acid (10) and emodin (12) with IC50 of 10 ∼ 120μM. The systematically study of antitumor constituents has firstly provided a chemical basis for the multitarget and synergistic anticancer activity of the genus Xanthium. The method presented could be utilized to guide the exploitation and promising utilization of X. orientale on cancer therapy.
Computationally efficient modeling and analysis of conductivity and sensitivity of CNT/polymer composites

Publisher: name: University of British Columbia

description: In this PhD thesis, an efficient model of conductivity for carbon nanotube (CNT)/polymer composites is developed, considering the effect of intertube tunneling through polymers, and the eletromechanical properties of the composites are estimated. The statistical nature of intertube distance is first investigated through numerical analysis for both two dimensional and three dimensional networks of CNTs. Considering the intertube distance as the key parameter of tunneling effect, analytical models are developed for tunneling conductivity at the CNT junctions and the overall conductivity of the composites. The model of composite conductivity provides significantly lower computational cost as compared to the numerical resistive network models, with reasonable accuracy. By incorporation of electron tunneling effects, this model also provides closer approximation to experimental results in comparison to the models based on percolation theory, which are highly relevant for filler/polymer composite applications designed around the percolation threshold. Using the conductivity model, the sensitivity of the composite films is estimated in presence of an organic gas. The change in the film resistance due to gas absorption is investigated for different CNT and gas concentrations. From the phase of reflected radio frequency (RF) signal, the wireless gas sensitivity is estimated for a lossless transmission system terminated with a composite film as the load. Films with lower filler concentration is found to have higher gas sensitivity and higher wireless sensitivity within a low range of gas pressure. This work is useful for design and development of biohazard gas sensors for real-time remote monitoring. Furthermore, the sensitivity of the composite films is estimated under the application of tensile strain. The influence of varying film thickness on the intertube distance in composite films is analyzed numerically. Then our analytical model is employed to estimate the composite conductivity and film sensitivity under mechanical strain. The partial alignment of CNTs introduced by the film thickness less than the CNT length is observed to have significant influence on the composite conductivity and strain sensitivity specially at low CNT concentration. The numerical results are compared with literature reports and experimental results. This work is helpful for strain sensing and stretchable switching applications.

description: Many-body quantum-mechanical scattering problem is solved asymptotically when the size of the scatterers (inhomogeneities) tends to zero and their number tends to infinity. A method is given for calculation of the number of small inhomogeneities per unit volume and their intensities such that embedding of these inhomogeneities in a bounded region results in creating a new system, described by a desired potential. The governing equation for this system is a non-relativistic Schrödinger equation described by a desired potential. Similar ideas were developed by the author for acoustic and electromagnetic (EM) wave scattering problems.

description: Due to an increased level of threat, the design of buildings to resist blast loads has gained importance. The most vulnerable component of the building is typically the cladding system, generally being lightweight and directly facing the hazard with large, exposed surface areas. A large number of cladding materials are available, with architectural intent constantly driving the development of new products and systems. Glazed façades are aesthetically appealing and are popular among architects. In this paper, the use of super-elastic shape memory alloy (SMA) to improve the blast resilience of a cable-supported system is explored. The critical component of these systems is the high strength steel material cable. In the present study it is rendered hybrid (Steel-SMA), by attaching SMA cable(s) to the steel cable at one or both ends, and the dynamic performance under blast is studied. It is shown that the introduction of SMA in the cable has the potential to improve the resilience of the façade system.

description: Electronic nematicity that spontaneously breaks rotational symmetry has been shown as a generic phenomenon in correlated quantum systems including high-temperature superconductors and the AV3Sb5 (A = K, Rb, Cs) family with a kagome network. Identifying the driving force has been a central challenge for understanding nematicity. In iron-based superconductors, the problem is complicated because the spin, orbital and lattice degrees of freedom are intimately coupled. In vanadium-based kagome superconductors AV3Sb5, the electronic nematicity exhibits an intriguing entanglement with the charge density wave order (CDW), making understanding its origin difficult. Recently, a new family of titanium-based kagome superconductors ATi3Bi5 has been synthesized. In sharp contrast to its vanadium-based counterpart, the electronic nematicity occurs in the absence of CDW. ATi3Bi5 provides a new window to explore the mechanism of electronic nematicity and its interplay with the orbital degree of freedom. Here, we combine polarization-dependent angle-resolved photoemission spectroscopy with density functional theory to directly reveal the band topology and orbital characters of the multi-orbital RbTi3Bi5. The promising coexistence of flat bands, type-II Dirac nodal line and nontrivial Z2 topological states is identified in RbTi3Bi5. Remarkably, our study clearly unveils the orbital character change along the G-M and G-K directions, implying a strong intrinsic inter-orbital coupling in the Ti-based kagome metals, reminiscent of iron-based superconductors. Furthermore, doping-dependent measurements directly uncover the orbital-selective features in the kagome bands, which can be well explained by the d-p hybridization. The suggested d-p hybridization, in collaboration with the inter-orbital coupling, could account for the electronic nematicity in ATi3Bi5.

description: What makes a façade beautiful? We are proud to announce the next regular issue of JFDE, which presents a variety of different interesting contributions. They include papers on the effects of plants growing over double façades, mitigation of seismic risks, blast resilience, and a comparative analysis of semi-permanent paperbased envelopes. Last but not least, one paper offers insight into the decision-making processes of façade designers and architects: ”What makes a façade beautiful?” is the title of one paper we are particularly happy to feature. We agree that the most successful façade examples – those that we actually remember and keep referring to as inspiration for our work – convey a certain message. A successful façade is the result of a good translation of the purpose, technical execution, functionality for the user, and finally: meaning. The latter refers to metaphysical aspects that are often difficult to explain. Façades and buildings do not simply provide space to host functions; they are displays of human activity in an urban context. They communicate, and they enable social interaction. At the same time, however, their built manifestation can limit us; In essence, architecture defines how we act and how we live. Good architecture makes us feel that it has the right answer to a problem and conveys a sense of well-being. This manifests as materiality, proportion, haptic quality, and elegance. Even Vitruvius talked about beauty and appropriateness as fundamental qualities of architecture. The paper does not offer a list of good examples as templates for repetition but rather sets out to explore the aesthetic preferences of designers. It is great to feature a contribution to the inspiring debate between architects and engineers, both defending their arguments about what a good façade is. Enjoy reading this issue of JFDE and keep contributing with inspiring papers.

description: The researchers collected data from 73 firms listed on the Tunisian Stock Exchange over the period 2010-2017 and applied multiple regression analysis to investigate the relationships between the variables. The study found a positive relationship between ownership concentration and firm value, and a negative relationship between earnings management and firm value. The study also found that ownership concentration moderates the negative relationship between earnings management and firm value. The authors discuss the implications of the findings for firms and investors, suggesting that firms should focus on developing transparent financial reporting practices to enhance their reputation and attract more investment. They also suggest that investors should pay close attention to the ownership structure of firms and how it may affect firm value. Overall, this study provides insights into the complex relationships between earnings management, ownership structure, and firm value, which can help inform strategies for enhancing the financial performance of firms.

description: The PowerSkin conference series is a biennial event organised cooperatively between TU München, TU Darmstadt, and TU Delft, which is already in its third edition, having started in 2017. The conference aims to address the role of building skins in accomplishing a carbon neutral building stock. The presented papers showcase recent scientific research and developments as well as projects related to building skins from the perspectives of material, technology, and design. Topics such as building operation, embodied energy, energy generation and storage in context of the envelope, energy, and environment are considered. The building envelope largely determines the energetic performance of the building, plays a significant part in the embodied energy of construction activities, defines the indoor qualities for the user and – quite importantly – defines the appearance of the building in an urban content. So, being central to all these aspects, the building envelope is the focus of research & development, engineering, and design. This is the scope of the PowerSKIN conferences, bringing research, industry, and users together to share and discuss new knowledge in an interdisciplinary environment (albeit an online environment this time around). The focus of the PowerSKIN Conference 2021 deals with the question of whether simplicity and robustness are in contradiction to good performance or whether they even complement each other. Hence the question Simplicity vs. Performance? is tackled throughout the conference from three points of view which define the thematic sessions of the Conference: Energy, Envelope, and Environment. This special issue of the Journal of Façade Design and Engineering dedicated to PowerSKIN 2021 showcases the most prominent and relevant papers of the conference, with the aim of enhancing their visibility for a larger audience.

Dynamic changes in adolescent endocannabinoid signaling in male rats : relevance to stress responsivity and emotional behaviour
Creators: name: Lee, Tiffany Tien-Yan
Publisher: name: University of British Columbia
Year: 2015

description: Adolescence is a period characterized by many distinct physical, behavioural and neural changes during the transition from child- to adulthood. In particular, adolescent neural changes often confer greater plasticity and flexibility, yet with this period of fluidity also comes the potential for heightened vulnerability to external perturbations such as stress exposure or recreational drug use. There is substantial evidence to suggest that factors such as adolescent stress exposure have longer lasting and sometimes more deleterious effects on an organism than stress exposure during adulthood. Moreover, the adolescent neuroendocrine response to stress exposure is different from that of adults, suggesting that further maturation of the adolescent hypothalamic-pituitary-adrenal (HPA) axis is required. The endocannabinoid system is a potential candidate underlying these age-dependent differences given that it is an important regulator of the adult hypothalamic-pituitary-adrenal (HPA) axis and neuronal development. Therefore, three studies were conducted in male rats to examine this possibility. The results of these experiments suggest that there is divergent age-dependent endocannabinoid tone between adolescents and adults (Chapter 2), age-dependent endocannabinoid regulation of HPA axis stress responsivity (Chapter 3) and a moderate organizational role of adolescent cannabinoid receptor type 1 (CB₁R) activation on adult stress responsivity and emotionality (Chapter 4). Taken together, the emerging picture suggests that the endocannabinoid system mediates interactions between HPA axis stress responsivity, emotionality and maturational stage. These findings may also be particularly relevant to our understanding of the development of affective disorders and the risks of adolescent cannabis consumption on emotional health and stress responsivity.
Exploring the Possibility of Using Bioreceptive Concrete in Building Façades

description: A bioreceptive material allows for biological content (biofilms) to grow on it, without necessarily affecting the material itself. If a bioreceptive concrete could therefore be integrated into a building façade, it could lead to green façades that do not need additional technical systems. As part of previous research by the authors, a promising bioreceptive concrete mixture was formulated. The aim of this research is to develop this concept by using the previously developed mixture to create a bioreceptive concrete façade panel prototype, made using commonly available materials, that can direct where the biological growth takes place. The latter is done by combining the bioreceptive concrete with a non-bioreceptive (UHPCbased) concrete in the same panel, through a two-stage pouring process. A biofilm was developed on this prototype panel and results show that full coverage of the bioreceptive parts of the panel can be achieved within two weeks under optimal growing conditions and biological growth can be directed. However, exterior survivability is an issue for now. The concept of bioreceptive façades therefore shows promise, yet further investigation into improving exterior survivability is necessary, while further research into the underlying ecology, material, economics, and climate effects is also necessary.

description: Although experts diverge on how best to improve spreadsheet quality, it is generally agreed that more time needs to be spent testing spreadsheets. Ideally, experienced and trained spreadsheet engineers would carry this out, but quite often this is neither practical nor possible. Many spreadsheets are a legacy, developed by staff that have since moved on, or indeed modified by many staff no longer employed by the organisation. When such spreadsheets fall into the hands of inexperienced, non-experts, any features that reduce error visibility may become a risk. Range names are one such feature, and this paper, building on previous research, investigates in a more structured and controlled manner the effect they have on the debugging performance of novice spreadsheet users.

description: Building envelopes incorporate a multitude of functions, such as structure, room enclosure, insulation, and aesthetic appeal, typically resulting in multi-material layered constructions. With the technology of additive manufacturing, geometrical freedom can instead be utilised to integrate functional requirements into mono-material building components. In this research, the additive manufacturing method of lightweight concrete extrusion and its potential for thermal performance via geometric customisation is explored. It investigates whether the insulating performance of wall components can be increased through the creation of closed cellular structures, and further, whether these performance features can be functionally graded by locally adapting the geometric properties. A design tool for closedcell wall geometries is created, which integrates lightweight concrete extrusion related fabrication constraints and takes into account thermal and structural performance considerations. Through the simulation of heat transfer, generated wall geometries are analysed for their thermal performance. By calculating the layer cycle times and determining the overhang during extrusion, the structural capacity during printing is validated. Finally, experimental manufacturing of 1:1 scale architectural prototypes is executed to test the feasibility of the concept.

description: We consider a simple model of an internally driven self-rotating object; a rotor, confined to two dimensions by a thin film of low Reynolds number fluid. We undertake a detailed study of the hydrodynamic interactions between a pair of rotors and find that their effect on the resulting dynamics is a combination of fast and slow motions. We analyse the slow dynamics using an averaging procedure to take account of the fast degrees of freedom. Analytical results are compared with numerical simulations. Hydrodynamic interactions mean that while isolated rotors do not translate, bringing together a pair of rotors leads to motion of their centres. Two rotors spinning in the same sense rotate with an approximately constant angular velocity around each other, while two rotors of opposite sense, both translate with the same constant velocity, which depends on the separation of the pair. As a result a pair of counter-rotating rotors are a promising model for controlled self-propulsion.

Potential of Façade-Integrated PVT With Radiant Heating and Cooling Panel Supported by a Thermal Storage for Temperature Stability and Energy Efficiency
Creators: name: Bayoumi, Mohannad
Publisher: name: Journal of Facade Design and Engineering
Year: 2021

description: Hybrid photovoltaic/thermal (PVT) systems combine electric and thermal energy generation and provide noiseless operation and space-saving features. As the efficiency of photovoltaic (PV) panels increases at low surface temperatures, this paper suggests combining the PVT panel with a radiant cooling and heating panel in one system. A thermal storage tank fluidly connects the heat-exchanging pipes at the back of the PVT system and radiant panel. The upper portion of the tank feeds the radiant panel and the lower portion of the tank is connected to the PVT system. The proposed device is expected to function in connection with a heat pump that feeds the thermal storage. Using the dynamic thermal simulation software Polysun, the performance of the proposed façade-integrated device was investigated while considering the surface temperatures and energy production in the moderate climatic condition of the city of Munich. The results indicate a substantial impact on the efficiency of the PV module with an increase of up to 35% in the electricity production of the PV due to the lowered surface temperature. The obtained results contribute to façade-supported cooling/heating and electricity generation through the novel coupling and integration of PV, PVT, and radiant cooling elements.

description: In this fourth part of the series presenting the Optical Gravitational Lensing Experiment (OGLE) microlensing studies of the dark matter halo compact objects (MACHOs) we describe results of the OGLE-III monitoring of the Small Magellanic Cloud (SMC). Three sound candidates for microlensing events were found and yielded the optical depth tau_SMC-OIII=1.30+-1.01 10^{-7}, consistent with the expected contribution from Galactic disk and SMC self-lensing. We report that event OGLE-SMC-03 is the most likely a thick disk lens candidate, the first of such type found towards the SMC. In this paper we also combined all OGLE Large and Small Magellanic Cloud microlensing results in order to refine the conclusions on MACHOs. All but one of OGLE events are most likely caused by the lensing by known populations of stars, therefore we concluded that there is no need for introducing any special dark matter compact objects in order to explain the observed events rates. Potential black hole event indicates that similar lenses can contribute only about 2 per cent to the total mass of the halo, which is still in agreement with the expected number of such objects.

description: Jede Stadt hat ihre ›Angsträume‹, ›Schmuddelecken‹ und ›Problemviertel‹. Gefahren und Bedrohungsgefühle sind nicht gleichmäßig in den Kommunen verteilt. Es gibt Gegenden, die gemieden werden und deren Bewohnerinnen und Bewohner als potenzielles Sicherheitsrisiko gelten. Es gibt Orte in größerer Nähe oder Entfernung zu möglichen Schadensquellen oder zu Rettungskräften; Orte mit gutem oder weniger gutem Zugang zu Fluchtwegen. Kurzum: Unsicherheit und Sicherheit sind ungleich verteilt. Gleichwohl ist es ein Ziel demokratischer Gesellschaften, Sicherheit zu gewähren: die Sicherheit, sich ohne Angst im öffentlichen Raum, aber auch im privaten Wohnumfeld bewegen zu können; die Sicherheit, in schwierigen Situationen wie Krankheit oder Alter eine Lebensgrundlage zu haben; die Sicherheit, vor Gericht ein gerechtes Verfahren erwarten zu können; aber auch die Sicherheit, nicht wegen des Aussehens, einer abweichenden Meinung oder eines anderen Lebensstils diskriminiert zu werden. Die vorliegenden Leitlinien nehmen eine ethische Perspektive auf Sicherheit in der Stadt ein. Die Aufgabe der gerechten Verteilung von Sicherheit wird dabei mit Fragen nach dem ›guten Leben‹ verknüpft. Probleme der Gewährleistung und Verteilung von Sicherheit können letztlich nicht ohne eine Diskussion der Frage ›Wie wollen wir leben?‹ gelöst werden. Die genannten Denkanstöße für die kommunale Sicherheitsarbeit sind angesichtsder Reichweite des Themas aus drei verschiedenen Blickwinkeln formuliert. Erstens wird die Bedeutung von Sicherheit im Kontext städtischen Zusammenlebens diskutiert und ins Verhältnis zu anderen Werten gesetzt. Zweitens werden Kriterien einer gerechten Verteilung von Sicherheit im Sinne faktisch verfügbarer Ressourcen oder konkreter Maßnahmen vorgeschlagen. Drittens werden Reflexionsfragen aufgeworfen, die bei der Beurteilung einzelner Maßnahmen helfen sollen.
Multi-active façade for Swedish multi-family homes renovation: Evaluating the potentials of passive design measures

description: In order to meet the Swedish energy efficiency objectives for the built environment until 2050, a particular building stock has to be addressed: the houses of the Million Homes Programme, an ambitious housing programme of the 1960s and 70s that resulted in a large number of standardized multi-family houses all over Sweden. These are in need of upgrading the energy and comfort quality to current standards, which provides an excellent opportunity to investigate the potentials of ‘prefabricated multi-active’ façades for refurbishments on large scale. While ‘prefabrication’ is linked to cost-effectiveness and high replicability, ‘multi-active’ addresses the potential of embedded active and passive measures for improved energy efficiency and energy regulation out of the façade. Integrated building services technologies, solar technologies or moveable components, such as shading systems, are considered active measures. Passive measures include physical and constructive measures, such as e.g. thermal insulation or selective coatings of glazing’s, and provide a “passive” energy flow control to improve the thermal quality of the building envelope. Many of these strategies are well-known, traditional solutions. Although they do not provide an energy-generating or -supplying function, they dynamically interact with environmental changes; preheating of supply air through the air cavity of a façade construction or adaptive thermal buffer zones are just few of many examples. The question is how traditional passive strategies can be used to contribute most effectively to the demanded energy efficiency. The paper presents first results from an assessment dealing with this question: Two traditional ‘passive’ façade strategies, a curtain wall system and closed balconies, have been analysed in regards to their impact on energy balance and their thermal behaviour in a defined renovation scenario. The assessment is aims to support the development of a multi-active facade concept suitable for large-scale refurbishments of the multi-family houses in Sweden, which is part of the initial phase in the pre-study “Multi-active façade”. The pre-study considers architectural, technological and constructive aspects, energy performance and indoor comfort optimization, but also economic feasibility and constraints to get replicable on large scale. So-called added values that concern the upgrade to modern living standards and expectations by inhabitants and the market value of the building are also touched. The paper discusses, based on a technology screening to identify suitable key measures, the energy saving potential and impact on thermal indoor comfort of two passive renovation strategies for facades.

description: Modern cities face a climatic problem due to the high proportion of sealed surfaces that increase the urban heat island (UHI) effect. Green surfaces offer a way to mitigate the UHI effect, as they positively influence the thermal energy storage and air temperature. To support an increase of green surfaces in the limited resources of cities, vertical spaces, e.g. façades, must be exploited. A possible realisation of a vertical green system are overgrown rope façades. Overgrown rope façades have pre-fitted ropes in front of façades on which climbing plants can grow. However, such systems have to deal with dynamic wind forces, which pose static challenges to the climbing system. In order to design such systems for the effective wind forces, so-called drag coefficients of the climbing plants must be known. Unfortunately, there are no guidelines or known values that provide such specific drag coefficients for climbing plants. In this study, based on a study review of relevant data for drag coefficients on deciduous and coniferous trees and leaves, findings are made comparable by applying the power function. Six critical factors to be considered are identified and a drag coefficient for climbing plants is derived from the investigations on deciduous trees. Their transferability to overgrown rope façades is analysed and discussed.

description: Electronic transport experiments involving the topologically protected states found at the surface of Bi2Se3 and other topological insulators require fine control over carrier density, which is challenging with existing bulk-doped material. Here we report on electronic transport measurements on thin (<100 nm) Bi2Se3 devices and show that the density of the surface states can be modulated via the electric field effect by using a top-gate with a high-k dielectric insulator. The conductance dependence on geometry, gate voltage, and temperature all indicate that transport is governed by parallel surface and bulk contributions. Moreover, the conductance dependence on top-gate voltage is ambipolar, consistent with tuning between electrons and hole carriers at the surface.

description: Prior research has consistently documented that the vast majority of sexual assault cases do not progress through the criminal justice system. However, there is less agreement in prior work on how race influences case progression, resulting in a literature frequently described as “inconsistent.” This systematic review examines all prior research that has included race as an independent variable in predicting the criminal justice system response to sexual assault (N = 34) in an effort to provide insight into seemingly disparate findings. We assess each study for the degree to which race was a focal point of interest, if and what theory was used to inform the investigation of race, how samples were drawn, and how and whose race was measured. Results illustrate that findings in prior research are not inconsistent, but rather unite to tell a nuanced story of the role of race in the criminal justice system response to sexual assault. The review demonstrates how decisions made by researchers throughout the research process can have significant impacts on reported findings, and how such findings may be used to influence policy and practice.

description: Higher moments of event-by-event net-proton multiplicity distributions are applied to search for the QCD critical point in the heavy ion collisions. It has been demonstrated that higher moments as well as moment products are sensitive to the correlation length and directly connected to the thermodynamic susceptibilities computed in the Lattice QCD and Hadron Resonance Gas (HRG) model. In this paper, we will present measurements for kurtosis ($κ$), skewness ($S$) and variance ($σ^{2}$) of net-proton multiplicity distributions at the mid-rapidity ($|y|<0.5$) and $0.4

PPP2R1A mutations in gynaecologic cancers: functional characterization and use in the genomic classification of tumours

description: Endometrial carcinoma is the most common gynaecological cancer in developed countries. The current endometrial pathologic classification system lacks reproducibility, which has hampered the development of new treatments for these cancers. The PP2A phosphatase complexes are responsible for regulating many cellular pathways, and may play a role in the deregulation of endometrial cancer-associated pathways. In this thesis, the role of PPP2R1A mutations in the subtype-specific classification of gynaecological tumours was investigated. Additionally, mutational profiles will be used to improve the classification of the subtypes of endometrial carcinomas. Lastly, the functional effect of mutant PPP2R1A on PP2A-subunit protein interactions will be determined, in the context of endometrial cancer cell lines. Next-generation and Sanger sequencing was used to determine the presence of mutations in endometrial and ovarian carcinomas. PPP2R1A isogenic endometrial-specific cell lines were generated using somatic cell gene knockout by homologous recombination. Co-immunoprecipitation and mass spectrometry was used to determine effects of the PPP2R1A W257L mutation on its ability to interact with PP2A subunits. Subtype-specific somatic PPP2R1A mutations were identified in endometrial serous carcinomas. Low-grade endometrial endometrioid carcinomas were defined by mutations in the genes: ARID1A, PTEN, PIK3CA, CTNNB1, and KRAS, whereas high-grade endometrioid also harbor TP53 mutations. Endometrial serous carcinomas harbor mutations in PPP2R1A, FBXW7, PIK3CA and TP53. Consequently, the molecular profiles proved useful in assisting classification of tumours with overlapping morphological features that cause irreproducibility in diagnoses. Proteomic analysis of isogenic cell lines determined that the PPP2R1A W257L mutation disrupts interaction with PPP2R5C and PPP2R5D subunits. In addition, PPP2R1A mutated protein caused an increased interaction with the endogenous PP2A inhibitor SET/I2PP2A. The integration of mutational profiles and other genomic features will be used to improve clinical and pathological classification in endometrial tumours that are difficult to diagnose. PPP2R1A mutations are likely playing a role in the transformation of gynaecological carcinoma, by disrupting PP2A subunit interactions with tumour suppressor functions. Increased interaction of mutant PPP2R1A with SET/I2PP2A adds another layer of complexity to the tumour suppressive role of PP2A. In the future, targeting the PP2A complex with novel therapeutics could provide an alternative method for treating gyneacological cancers with poor outcomes.

description: We derive the most general first order symmetry operator for the Dirac equation coupled to arbitrary fluxes. Such an operator is given in terms of an inhomogenous form omega which is a solution to a coupled system of first order partial differential equations which we call the generalized conformal Killing-Yano system. Except trivial fluxes, solutions of this system are subject to additional constraints. We discuss various special cases of physical interest. In particular, we demonstrate that in the case of a Dirac operator coupled to the skew symmetric torsion and U(1) field, the system of generalized conformal Killing-Yano equations decouples into the homogenous conformal Killing-Yano equations with torsion introduced in [arXiv:0905.0722] and the symmetry operator is essentially the one derived in [arXiv:1002.3616]. We also discuss the Dirac field coupled to a scalar potential and in the presence of 5-form and 7-form fluxes.

description: Overgrown rope façades offer a space-saving possibility to make cities greener while counteracting the effect of the urban heat island (UHI). Unfortunately, there are no design models that adequately characterise the interaction between wind and plants for the calculation of wind loads. In the preceding study about overgrown rope façades (Arnold et al., 2021), a design model was deduced from flow force studies on trees and a drag coefficient for plants on overgrown rope façades was derived from drag resistance measurements of deciduous trees. This drag coefficient has not been validated. In this study, wind load tests in a turbulent wind tunnel were performed on five climbing plants to validate the drag coefficient. For this purpose, a prototype of a turbulent wind tunnel with an active grid that simulates gusts for a chaotic turbulent flow was built and various overgrown rope samples were measured. Based on the measured data, the 95% characteristic value of the drag coefficients was calculated using a statistical method. These drag coefficients can be applied to buildings at different speeds by means of E-values and B-values, thus allowing the design optimisation of plant climbing systems. This work does not deal with the interaction between the façade surface and overgrown rope plant in front of the façade, which requires further research.
