title: Der Zusammenhang zwischen situationaler Stärke und Arbeitsmotivation unter Berücksichtigung der Identifikation mit der Organisation
Creators: name: Martinelli, Julia-Theresa
Year: 2023

description: In der vorliegenden Masterarbeit wird die Auswirkung von Situationaler Stärke auf die Arbeitsmotivation untersucht. Situationale Stärke umschreibt den Grad der Eindeutigkeit und Klarheit einer Situation, welche das Verhalten einer Person beeinflusst und ihre Handlungsspielräume einschränken oder erweitern kann. Die Hypothese besagt, dass eine hohe Situationale Stärke dazu führt, dass die kontrollierte bzw. extrinsische Motivation steigt, jedoch die autonome bzw. intrinsische Motivation sinkt. Der Einfluss der Identifikation mit der Organisation der einzelnen Mitarbeiter:innen wird hierbei als moderierende Variable berücksichtigt. Zur Überprüfung wurde eine querschnittliche Studie mithilfe eines Fragebogens am österreichischen Bundesheer durchgeführt. Es wurden einseitige t-Tests durchgeführt, die zu dem Ergebnis kamen, dass sich Situationale Stärke positiv sowohl auf die autonome als auch auf die kontrollierte Arbeitsmotivation auswirkt. Zur Überprüfung der Auswirkung der Identifikation mit der Organisation wurde eine klassische Moderation durchgeführt, und es ergab sich, dass der Moderator den Zusammenhang zwischen Situationaler Stärke und der kontrollierten sowie der autonomen Arbeitsmotivation verstärkt. Explorativ wurde ein Gruppenvergleich in Bezug auf die Arbeitsmotivation zwischen militärischem und nicht militärischem Personal durchgeführt. Die beiden Gruppen unterscheiden sich in der autonomen Arbeitsmotivation, nicht aber in der kontrollierten Arbeitsmotivation und dem Gesamtscore. Zusammenfassend lässt sich feststellen, dass eine hohe Situationale Stärke positive Auswirkungen auf die Arbeitsmotivation hat. Es werden praktische Implikationen abgeleitet sowie Vorschläge für zukünftige Forschungsthemen gemacht.

description: Recently, Bravyi and König have shown that there is a tradeoff between fault-tolerantly implementable logical gates and geometric locality of stabilizer codes. They consider locality-preserving operations which are implemented by a constant depth geometrically local circuit and are thus fault-tolerant by construction. In particular, they shown that, for local stabilizer codes in D spatial dimensions, locality preserving gates are restricted to a set of unitary gates known as the D-th level of the Clifford hierarchy. In this paper, we elaborate this idea and provide several extensions and applications of their characterization in various directions. First, we present a new no-go theorem for self-correcting quantum memory. Namely, we prove that a three-dimensional stabilizer Hamiltonian with a locality-preserving implementation of a non-Clifford gate cannot have a macroscopic energy barrier. Second, we prove that the code distance of a D-dimensional local stabilizer code with non-trivial locality-preserving m-th level Clifford logical gate is upper bounded by $O(L^{D+1-m})$. For codes with non-Clifford gates (m>2), this improves the previous best bound by Bravyi and Terhal. Third we prove that a qubit loss threshold of codes with non-trivial transversal m-th level Clifford logical gate is upper bounded by 1/m. As such, no family of fault-tolerant codes with transversal gates in increasing level of the Clifford hierarchy may exist. This result applies to arbitrary stabilizer and subsystem codes, and is not restricted to geometrically-local codes. Fourth we extend the result of Bravyi and König to subsystem codes. A technical difficulty is that, unlike stabilizer codes, the so-called union lemma does not apply to subsystem codes. This problem is avoided by assuming the presence of error threshold in a subsystem code, and the same conclusion as Bravyi-König is recovered.

description: The most productive star factories in the Universe are the progenitors of galaxy clusters at the nodes of cosmic filaments, the so called protoclusters. The extended nature of these extraordinary sites and their bright sub-millimeter emission make them detectable by the Planck satellite. We have observed a sample of 18 of these Planck-selected protocluster candidates at millimeter wavelengths with the IRAM 30-m telescope to reveal their molecular gas reservoirs and the mechanisms at the origin of their prodigious star formation rates. We detected 40 CO lines in 24 bright Herschel sources over 14 fields at an average redshift of 2.25. The CO redshifts support the idea that some of these fields contain protoclusters. The CO-detected sources are mainly normal SFGs, with only ∼20% undergoing a starburst phase. Their large star formation rates, ~1000 M⊙/yr on average, are supported by large (a few 10^11 M⊙) cold gas reservoirs. The CO spectral line energy distribution, available for ten sources implies low gas excitation in most of the cases. These properties hint to extended and cold molecular gas reservoirs at low excitation and a steady fueling mechanism. Millimeter and CO observations at higher spatial resolution with NOEMA and ALMA have recently been obtained for two sources to test the proposed fueling scenario, and gain more insights on the origin of their prodigious star formation activity. The implications of these findings on the formation scenario of the most massive passive galaxies found in local clusters will also be discussed.

The role of the epidermal growth factor signalling pathway in regulation of skeletal muscle fibre type
Creators: name: Ciano, Margherita
Publisher: name: Imperial College London
Year: 2018

description: Deranged skeletal muscle fibre type proportion is a common characteristic in a number of chronic diseases such as chronic obstructive pulmonary disease (COPD), cardiac failure, type 2 diabetes and obesity. In these conditions, there is a low quadriceps proportion of slow-twitch (ST) fibres, relative to fast-twitch (FT) fibres, associated with exercise limitation, insulin resistance, adiposity and, in COPD, mortality. Although skeletal muscle fibre types can switch and the benefits of increased ST fibre to exercise capacity, diabetes and obesity risk have been demonstrated in genetically modified animals, the molecular mechanisms regulating the switch between fibres are not completely understood. Therefore, at the present, druggable targets to increase ST fibre proportion are not available. Pathway analysis of microarray data from both COPD patients’ quadriceps (with high proportion of FT fibre) and published mouse data identified the EGF pathway to be associated with FT fibre phenotype, suggesting that the EGF pathway may be a suppressor of the ST fibre phenotype. My preliminary (MRes) data indicated that inhibition of the EGF-receptor (EGFR) in vitro promotes expression of ST fibre-associated genes, while suppressing FT fibre-associated gene expression. In this thesis, I aimed to consolidate the preliminary in vitro data and determine whether EGFR depletion promotes the ST phenotype in skeletal muscle in zebrafish (Danio rerio) and in mouse (Mus musculus). Pharmacological inhibition and EGFR silencing in vitro increased ST, including mitochondrial, gene and protein expression and increased glucose transporter 4 (GLUT4) transcripts. In zebrafish, egfra depletion by genome editing increased the number of ST fibres and mitochondrial content. In mice, pharmacological inhibition of EGFR increased GLUT4 gene expression in the tibialis anterior (TA). Together, these data indicate that EGFR may be involved in the regulation of the skeletal muscle fibre type gene expression and may play a role in chronic diseases characterised by deranged fibre type proportions.

description: It was South Korea’s president Park Geun-hye who coined the Phrase “Unification is a Jackpot.” On being awarded an honorary doctorate by the Technical University of Dresden, Ms. Park delivered a speech outlining her vision and proposals for the unification of North and South Korea. If the North Korean government abandoned its nuclear programme, the Republic of Korea would be willing to improve the living conditions of the people living in the North by promoting infrastructure measures. The focus should be on the people and their needs (e.g., family reunions) as well as on narrowing the cultural distance between the two countries.

description: The interpretation of present and future neutrino experiments requires accurate theoretical predictions for neutrino-nucleus scattering rates. Neutrino structure functions can be reliably evaluated in the deep-inelastic scattering regime within the perturbative QCD (pQCD) framework. At low momentum transfers ($Q^2 \le {\rm few}$ GeV$^2$), inelastic structure functions are however affected by large uncertainties which distort event rate predictions for neutrino energies $E_ν$ up to the TeV scale. Here we present a determination of neutrino inelastic structure functions valid for the complete range of energies relevant for phenomenology, from the GeV region entering oscillation analyses to the multi-EeV region accessible at neutrino telescopes. Our NNSF$ν$ approach combines a machine-learning parametrisation of experimental data with pQCD calculations based on state-of-the-art analyses of proton and nuclear parton distributions (PDFs). We compare our determination to other calculations, in particular to the popular Bodek-Yang model. We provide updated predictions for inclusive cross sections for a range of energies and target nuclei, including those relevant for LHC far-forward neutrino experiments such as FASER$ν$, SND@LHC, and the Forward Physics Facility. The NNSF$ν$ determination is made available as fast interpolation LHAPDF grids, and can be accessed both through an independent driver code and directly interfaced to neutrino event generators such as GENIE.

Fibre-reinforced additive manufacturing: from design guidelines to advanced lattice structures
Creators: name: Plocher, János
Publisher: name: Imperial College London
Year: 2021

description: In pursuit of achieving ultimate lightweight designs with additive manufacturing (AM), engineers across industries are increasingly gravitating towards composites and architected cellular solids; more precisely, fibre-reinforced polymers and functionally graded lattices (FGLs). Control over material anisotropy and the cell topology in design for AM (DfAM) offer immense scope for customising a part’s properties and for the efficient use of material. This research expands the knowledge on the design with fibre-reinforced AM (FRAM) and the elastic-plastic performance of FGLs. Novel toolpath strategies, design guidelines and assessment criteria for FRAM were developed. For this purpose, an open-source solution was proposed, successfully overcoming the limitations of commercial printers. The effect of infill patterns on structural performance, economy, and manufacturability was examined. It was demonstrated how print paths informed by stress trajectories and key geometric features can outperform conventional patterns, laying the groundwork for more sophisticated process planning. A compilation of the first comprehensive database on fibre-reinforced FGLs provided insights into the effect of grading on the elastic performance and energy absorption capability, subject to strut-and surface-based lattices, build direction and fibre volume fraction. It was elucidated how grading the unit cell density within a lattice offers the possibility of tailoring the stiffness and achieving higher energy absorption than ungraded lattices. Vice versa, grading the unit cell size of lattices yielded no effect on the performance and is thus exclusively governed by the density. These findings help exploit the lightweight potential of FGLs through better informed DfAM. A new and efficient methodology for predicting the elastic-plastic characteristics of FGLs under large strain deformation, assuming homogenised material properties, was presented. A phenomenological constitutive model that was calibrated based upon interpolated material data of uniform density lattices facilitated a computationally inexpensive simulation approach and thus helps streamline the design workflow with architected lattices.

description: Mushrooms have health benefits, including anti-tumoral properties. We evaluated the cytotoxic and cell death induction effects of water-soluble extracts of Pleurotus ostreatus and Pleurotus eryngii mycelium in the cervical cancer cell lines HeLa (HVP18+) and SiHa (HVP16+) as well as the non-tumoral cell line HaCaT. Both Pleurotus extracts presented similar protein patterns from 190 to 10 kDa and displayed protease activity on a gelatine substrate. The mycelium extracts of both Pleurotus strains induced a dose-dependent cytotoxic effect on HPV+ cells IC50 65 µg), whereas HaCaT cells were less susceptible (IC50 90 µg). The cytotoxic effect at the IC50 concentration was not associated with apoptosis, the activation of Caspases-3/7 was not significantive; only P. eryngii induced a moderate (1.2-fold) increase in SiHa cells. Pleurotus extracts induced autophagy, mainly in SiHa cells (4.3-fold). Neither extracts induced changes in p53 protein expression, suggesting that the cytotoxic effect could be due to p53-independent pathways.

description: Recently [L. Lacasa and J. Gómez-Gardeñes, Phys. Rev. Lett. {\bf 110}, 168703 (2013)], a fractal dimension has been proposed to characterize the geometric structure of networks. This measure is an extension to graphs of the so called {\em correlation dimension}, originally proposed by Grassberger and Procaccia to describe the geometry of strange attractors in dissipative chaotic systems. The calculation of the correlation dimension of a graph is based on the local information retrieved from a random walker navigating the network. In this contribution we study such quantity for some limiting synthetic spatial networks and obtain analytical results on agreement with the previously reported numerics. In particular, we show that up to first order the correlation dimension $β$ of integer lattices $\mathbb{Z}^d$ coincides with the Haussdorf dimension of their coarsely-equivalent Euclidean spaces, $β=d$.

description: In Österreich lebende DaZ-Lernende werden im Alltag häufig mit Dialekten konfrontiert, was zu Verständnisschwierigkeiten, Frustration und Verwirrung führen kann. Im DaZ-Unterricht herrscht jedoch die Standardsprache als jene Varietät vor, die vermittelt wird. Für die sprachliche und gesellschaftliche Teilhabe ist allerdings auch das Verständnis der Dialekte notwendig. Diese Masterarbeit beschäftigt sich deswegen damit, wie Dialekte im DaZ-Unterricht im bairischen Dialektraum in Österreich thematisiert werden. Dafür werden sechs DaZ-Lehrpersonen, welche in der Erwachsenenbildung arbeiten, in leitfadengestützten Expert*inneninterviews dazu befragt, wie sie im Unterricht mit dieser Thematik umgehen. Dabei wurde herausgefunden, dass DaZ-Lernende allgemein ein großes Interesse an den Dialekten zeigen und im Unterricht häufig nach einzelnen Wörtern und non-standardsprachlichen Ausdrücken fragen. Dieses Interesse ist für die Lehrpersonen einer der Hauptgründe, weshalb sie für sich selbst entschieden haben, nicht nur auf die Standardsprache einzugehen, sondern auch auf dialektale Varietäten. Sie thematisieren dabei entweder lediglich die lexikalische Ebene oder zum Teil auch andere sprachliche Bereiche. Einige Lehrer*innen erstellen dafür eigenes Material; sehr beliebt sind auch authentische Materialien. Es werden viele positive Aspekte und Vorteile der Dialektthematisierung aufgezeigt, besonders das rezeptive Verständnis wird als notwendig hervorgehoben. Nachteile werden von den Lehrkräften keine gesehen. Eine Thematisierung der Dialekte im DaZ-Unterricht wird mit Hinblick auf die Ergebnisse sehr empfohlen.

description: Zinc containing ternary nitrides, in particular ZnSnN2 and ZnGeN2, have great potential as earth-abundant and low toxicity light-absorbing materials. The incorporation of oxygen in this system – may it be intentional or unintentional – affects the crystal structure of the materials as well as their optical band gaps. Herein, we explore the origins of structural changes between the wurtzite type and its hettotype, the β-NaFeO2 type, and highlight the effect of oxygen. Furthermore, we study the electronic structure and bonding in order to understand the reason for the narrower band gap of zinc germanium oxide nitrides as opposed to pure zinc germanium nitride.

description: 5,7-Dihydroxy-2-(1,2-isopropyldioxy-4-oxo-cyclohex-5-enyl)-chromen-4-one (DICO) is a novel non-aromatic B-ring flavonoid, isolated mainly from Macrothelypteris viridifrons and has anti-tumour properties. In this study, we investigated the cytotoxicity and underlying biochemical pathways leading to cell death, in response to DICO treatment of a human colon cancer cell line HT-29. Our results indicated that DICO induced apoptosis by elevating the generation of reactive oxygen species, which could be quenched by the antioxidants N-acetyl cysteine. In addition, activation of signal transducer and activator of transcription 3 and suppression of nuclear factor kappa B played a crucial role in DICO-induced apoptosis. Overall, our results provide mechanistic insights into the apoptotic action of a potential anti-tumour drug, DICO.

title: Sexismus und (anti-)feministische Ideen in "Bridget Jones - Schokolade zum Frühstück"
Creators: name: Hainthaler, Katharina
Year: 2023

description: Die vorliegende Masterarbeit umfasst eine feministisch-ethische Filmanalyse des Filmes „Bridget Jones – Schokolade zum Frühstück“ (Maguire, 2001). Dieser behandelt feministische sowie antifeministische Motive und Ideen, die eng miteinander verwoben sind, was typisch für ein Produkt der postfeminist media culture ist. Der Film lässt sich dem Genre chick flick zuordnen und befasst sich dementsprechend mit Themen, die Frauen auf eine andere Art und Weise als Männer betreffen. Im Film werden unter anderem ethisch relevante Themen wie die Diskriminierung von Frauen am Arbeitsplatz, Sexualisierung und Objektifizierung von Frauen, und die Selbstverwirklichung von Frauen, besonders in Bezug auf heteronormative Beziehungen und Reproduktion, behandelt. Anhand des Films werden diese Themen einer feministisch-ethischen Filmanalyse in Hinblick auf Ungerechtigkeiten und Ungleichheiten aufgrund des Geschlechts unterzogen. Dabei werden filmische Mittel sowohl auf auditiver als auch auf visueller Ebene untersucht - das bedeutet, dass zum Beispiel die Kameraeinstellungen, die Filmmusik und die Sprache im Film analysiert werden, um den Humor des Films, der auf Kosten der weiblichen Hauptfigur basiert, aus feministisch-ethischer Sicht zu destruieren und so Aussagen über feministische und antifeministische Ideen des Filmes treffen zu können.
description: This master's thesis comprises a feminist-ethical film analysis of the film "Bridget Jones - Diary" (Maguire, 2001). This film deals with feminist as well as anti-feminist ideas that are entangled, which is typical for a product of postfeminist media culture. The film can be categorized as chick flick genre and accordingly deals with issues that affect women in a different way than men. Among other things, the film addresses ethically relevant issues such as discrimination against women in the workplace, sexualization and objectification of women, and women's self-actualization, especially in relation to heteronormative relationships and reproduction. Through the film, these themes are subjected to a feminist ethical film analysis in terms of injustices and inequalities based on gender. In doing so, cinematic devices, such as prominent camera angles, film music and language are examined on both an auditory and visual level in order to deconstruct the humor of the film, which is based at the expense of the female main character, from a feminist-ethical point of view and thus to be able to make statements about feminist and anti-feminist ideas of the film.

description: We introduce a class of two-dimensional non-resonant single-phase phononic materials and investigate its peculiar dispersion characteristics. The material consists of a thin plate-like structure with an embedded periodic lattice of Acoustic Black Holes. The use of these periodic tapers allows achieving remarkable dispersion properties such as Zero Group Velocity in the fundamental modes, negative group refraction index, bi-refraction, and mode anisotropy. The dispersion properties are numerically investigated using a three-dimensional supercell plane wave expansion method. The effect on the dispersion characteristics of key geometric parameters of the black hole, such as the taper profile and the residual thickness, are also explored.

description: Despite their ubiquity in terrestrial ecosystems, arbuscular mycorrhizal fungi (AMF) experience dispersion constraints and thus depend on the spatial distribution of the plant hosts. Our understanding of fungal-plant interactions with respect to their spatial distributions and implications for the functioning of the symbiosis remain limited. We here manipulated the location of habitat patches of Medicago lupulina in two experiments to explore the responses of AMF root colonization and extraradical hyphae. We tested the specific hypothesis that AMF-plant habitats high in connectance would stimulate root colonization and induce denser functional root colonization (colonization rate of arbuscules plus coils) because of higher propagule availability between nearby host plant patches (experiment 1). In experiment 2, we anticipated similar responses in mixed habitats of different soil fertility, namely phosphorus-fertilized or unfertilized soil, and anticipated a higher density of extraradical hyphae in the soil connecting the habitats with increased functional root colonization. In agreement with our hypothesis, we found the highest total and functional root colonization in unfragmented micro-landscapes, describing landscapes that occur within a spatial scale of a few centimeters with the AMF-plant habitats positioned adjacent to each other. In the second experiment, overdispersed micro-landscapes promoted functional root colonization. This study provides experimental evidence that the spatial distribution of habitats can determine AMF abundance at the microscale.

description: We present two complementary algorithms suitable for using focal-plane measurements to control a wavefront corrector with an extremely high spatial resolution. The algorithms use linear approximations to iteratively minimize the aberrations seen by the focal-plane camera. The first algorithm, Fast & Furious (FF), uses a weak-aberration assumption and pupil symmetries to achieve fast wavefront reconstruction. The second algorithm, an extension to FF, can deal with an arbitrary pupil shape; it uses a Gerchberg-Saxton style error reduction to determine the pupil amplitudes. Simulations and experimental results are shown for a spatial light modulator controlling the wavefront with a resolution of 170 x 170 pixels. The algorithms increase the Strehl ratio from ~0.75 to 0.98-0.99, and the intensity of the scattered light is reduced throughout the whole recorded image of 320 x 320 pixels. The remaining wavefront rms error is estimated to be ~0.15 rad with FF and ~0.10 rad with FF-GS.

description: The solid solution series between Cu2ZnSnSe4, crystallizing in the kesterite type structure, and Cu2MnSnSe4, adopting the stannite type structure, i.e. Cu2(Zn1−xMnx)SnSe4, was studied by a combination of neutron and X-ray powder diffraction. Powder samples with 0 ≤ x ≤ 1 were synthesized by the solid state reaction of the pure elements and it was confirmed by wavelength-dispersive X-ray spectroscopy that each contained a homogeneous, off-stoichiometric quaternary phase. The lattice parameters and cation site occupancy factors were determined simultaneously by the Rietveld analysis of the neutron and X-ray powder diffraction data. The refined site occupancy factors were used to determine the average neutron scattering length of the cation sites in the crystal structure of the Cu2(Zn1−xMnx)SnSe4 mixed crystals, from which a cation distribution model was derived. For the end member Cu2ZnSnSe4, the disordered kesterite structure was confirmed and for Cu2MnSnSe4, the stannite structure was confirmed. The cross-over from the kesterite to stannite type structure by Zn2+ ↔ Mn2+ substitution in the Cu2Zn1−xMnxSnSe4 solid solution can be seen as a cation re-distribution process among the positions (0, 0, 0), (0, ½, ¼) and (0, ¼, ¾), including Cu+, Zn2+ and Mn2+. The Sn4+ cation does not take part in this process and remains on the 2b site. Moreover, the cross-over is also visible in the ratio of the lattice parameters c/(2a), showing a characteristic dependence on the chemical composition. The order parameter Q, the quantitative measure of Cu/BII disorder (BII = Zn and Mn), shows a distinct dependence on the Mn/(Mn + Zn) ratio. In Zn-rich Cu2(Zn1−xMnx)SnSe4 mixed crystals, the order parameter Q ∼ 0.7 and drops to Q ∼ 0 (complete Cu/BII disorder) in the compositional region 0.3 ≥ x ≥ 0.7. In Mn-rich Cu2(Zn1−xMnx)SnSe4 mixed crystals, adopting the stannite type structure, the order parameter reaches almost Q ∼ 1 (order). Thus, it can be concluded that only Mn-rich Cu2(Zn1−xMnx)SnSe4 mixed crystals do not show Cu/BII disorder. A similar trend of the dependence on the chemical composition of both Cu/BII-disorder and the band gap energy Eg in Cu2(Zn1−xMnx)SnSe4 mixed crystals was observed.

description: The rapid evolution of new SARS-CoV-2 variants poses a continuing threat to human health. Vaccination has become the primary therapeutic intervention. The goal of the current work was the construction of immunogenic virus-like particles (VLPs). Here, we describe a human cell line for cost-efficient and scalable production of immunogenic SARS-CoV-2 VLPs. The modular design of the VLP-production platform facilitates rapid adaptation to new variants. Methods: The N, M-, and E-protein genes were integrated into the genome of Expi293 cells (ExpiVLP_MEN). Subsequently, this cell line was further modified for the constitutive expression of the SARS-CoV-2 spike protein. The resulting cell line (ExpiVLP_SMEN) released SARS-CoV-2 VLP upon exposure to doxycycline. ExpiVLP_SMEN cells were readily adapted for VLP production in a 5 L bioreactor. Purified VLPs were quantified by Western blot, ELISA, and nanoparticle tracking analysis and visualized by electron microscopy. Immunogenicity was tested in mice. Results: The generated VLPs contained all four structural proteins, are within the size range of authentic SARS-CoV-2 virus particles, and reacted strongly and specifically with immunoserum from naturally infected individuals. The VLPs were stable in suspension at 4 °C for at least 10 weeks. Mice immunized with VLPs developed neutralizing antibodies against lentiviruses pseudotyped with the SARS-CoV-2 spike protein. The flexibility of the VLP-production platform was demonstrated by the rapid switch of the spike protein to a new variant of concern (BA.1/Omicron). The present study describes an efficient, scalable, and adaptable production method of immunogenic SARS-CoV-2 VLPs with therapeutic potential.

description: Engineering synthetic materials that mimic the remarkable complexity of living organisms is a fundamental challenge in science and technology. We study the spatiotemporal patterns that emerge when an active nematicfilm of microtubules and molecular motors is encapsulated within a shape-changing lipid vesicle. Unlike in equilibrium systems, where defects are largely static structures, in active nematics defects move spontaneously and can be described as self-propelled particles. The combination of activity, topological constraints and vesicle deformability produces a myriad of dynamical states. We highlight two dynamical modes: a tunable periodic state that oscillates between two defect configurations, and shape-changing vesicles with streaming filopodia-like protrusions. These results demonstrate how biomimetic materials can be obtained when topological constraints are used to control the non-equilibrium dynamics of active matter.
A Holistic, Non-algorithmic View of Cultural Evolution: Commentary on Review Article by Prof. Liane Gabora

description: There is surely some truth to the notion that culture evolves, but the Darwinian view of culture is trivial. Gabora does two things in this paper. First, she levels a reasoned and devastating attack on the adequacy of a Darwinian theory of cultural evolution, showing that cultural evolution violates virtually all prerequisites to be encompassed by Darwin's standard theory. Second, she advances the central concept that it is whole world views that evolve. A world view emerges when the capacity of memories to evoke one another surpasses a phase transition yielding a richly interconnected conceptual web, a world view. She proposes that cultural evolves not through a Darwinian process such as meme theory, but through communal exchange of facets of world views. Each section of her argument is completely convincing.

description: Discovery of protein-binding fragments for precisely defined binding sites is an unmet challenge to date. Herein, formylglycine is investigated as a molecular probe for the sensitive detection of fragments binding to a spatially defined protein site . Formylglycine peptide 3 was derived from a phosphotyrosine-containing peptide substrate of protein tyrosine phosphatase PTP1B by replacing the phosphorylated amino acid with the reactive electrophile. Fragment ligation with formylglycine occurred in situ in aqueous physiological buffer. Structures and kinetics were validated by NMR spectroscopy. Screening and hit validation revealed fluorinated and non-fluorinated hit fragments being able to replace the native phosphotyrosine residue. The formylglycine probe identified low-affinity fragments with high spatial resolution as substantiated by molecular modelling. The best fragment hit, 4-amino-phenyl-acetic acid, was converted into a cellularly active, nanomolar inhibitor of the protein tyrosine phosphatase SHP2.

description: Various classes of exotic singularity models have been studied as possible mimic models for the observed recent acceleration of the universe. Here we further study one of these classes and, under the assumption that they are phenomenological toy models for the behavior of an underlying scalar field which also couples to the electromagnetic sector of the theory, obtain the corresponding behavior of the fine-structure constant $α$ for particular choices of model parameters that have been previously shown to be in reasonable agreement with cosmological observations. We then compare this predicted behavior with available measurements of $α$, thus constraining this putative coupling to electromagnetism. We find that values of the coupling which would provide a good fit to spectroscopic measurements of $α$ are in more than three-sigma tension with local atomic clock bounds. Future measurements by ESPRESSO and ELT-HIRES will provide a definitive test of these models.

description: The present contribution aims to provide an overview of the large collection of soft stone vessels and lids coming from the collective tomb Long Collective Grave 1 in the Dibbā al-Bayah funerary complex, along with a brief description and evaluation of the tomb itself. The corpus of material here discussed has been recovered during the 2012 season, and it mainly encompasses the chronological span between the second and first millennium BC. The findings are classified and organised in tables according to their chronological phase, and successively on the basis of their morphology and decorative patterns to which a major focus is addressed. Given the outstanding manufacturing of the materials, the finely incised and even plastic decorations, and their state of preservation, an assessment of such remarkable corpus, although partial, contributes significantly to the study of the diffusion and production of stone vessels in South-East Arabia.
