description: To manufacture semi-finished hybrid workpieces with tailored properties, a finite element simulation assisted process chain design was investigated. This includes the process steps of cross wedge rolling, hot geometry inspection, induction hardening, and fatigue testing. The process chain allows the utilisation of material combinations such as high-strength steels with low-cost and easy to process steels. Here, plasma transferred arc welding is applied to supply the process chain with hybrid specimen featuring different steel grades. An overview of the numerical approaches to consider the various physical phenomena in each of the process steps is presented. The properties of the component behaviour were investigated via the finite element method (FEM) and theoretical approaches. At first, the manufacturing of a hybrid workpiece featuring a near net shape geometry with improved mechanical properties due to recrystallising the weld was computed, using the example of a cross wedge rolling process. The rolling process was designed by means of FEM to determine suitable process parameters and to reduce experimental testing. An optical multi-scale geometry inspection of the hot workpiece is meant to be carried out after each manufacturing step to detect potential undesired forming or cooling-induced deformations. Due to the heat transfer from the hot component to the ambient medium, an optical measurement is affected by the developing inhomogeneous refractive index field in air. To gain a basic understanding of the refractive index field and induced light deflection effects, computations were conducted using heat transfer and ray tracing simulations. According to the proposed process route, a subsequent local heat treatment of the hybrid component is required to adapt the mechanical properties by a spray cooling assisted induction hardening. The heat treatment step was computed via a 2D FEM calculation. After finishing by machining, the hybrid material shafts are examined in fatigue tests under load conditions. To predict the component’s lifetime under rolling contact fatigue, a damage accumulation model was combined with an FE simulation. The resulting residual stress state after quenching and the geometry after the finishing process were used as input data for the fatigue life calculations.

description: If bone defects occur, the body’s own healing mechanism can close them below a critical size; for larger defects, bone autografts are used. These are typically cut from the same person’s hip in a second surgery. Consequently, the risk of complications, such as inflammations, rises. To avoid the risks resulting from the second surgery, absorbable, open-pored implants can be used. In the present study, the suitability of different magnesium alloys as absorbable porous bone substitute material has been investigated. Using the investment casting process with its design flexibility, the implant’s structure can be adapted to the ideal pore geometry with respect to bone ingrowth behavior. Different magnesium alloys (Mg-La2, LAE442, and ZX61) were studied and rated in terms of their degradation rate, bone ingrowth behavior, biocompatibility, and resorbability of the individual alloying elements.

description: The influence of the bond on grinding processes remains one uncertainty in the investigation of grinding tool behavior. Among others, this is due to the lack of knowledge about the interactions between the grain/bond interface and the grinding process loads. Understanding these interactions allows for further process development by adjusting the bond to the grinding application. The interactions at the grain/bond interface during grinding depend on the single grain thermomechanical loads as well as the tool properties. This paper presents an approach to provide the boundary conditions which are needed to model the interactions at the grain/bond interface. The machining of tungsten carbide with a bronze-bonded diamond tool is considered as use case. For this purpose, a novel kind of tool extracted from the grinding layer that serves to quantify the loads affecting the active grains and consequently their grain/bond interfaces during grinding is developed. The results of different grain orientations are plotted in a so-called Acu diagram, which gives an overview of the mechanical loads for different grain orientations and chip thickness values, as they occur during grinding due to the stochastic orientation and distribution of the abrasive grains in the grinding tool. It is shown that depending on the engagement conditions, the single grain-cutting force can reach up to 300 N by chip thickness values of 20 μm, which implies different wear behavior of the active grains.

description: Cystobactamids belong to the group of arene-based oligoamides that effectively inhibit bacterial type IIa topoisomerases. Cystobactamid 861-2 is the most active member of these antibiotics. Most amide bonds present in the cystobactamids link benzoic acids with anilines and it was found that some of these amide bonds undergo chemical and enzymatic hydrolysis, especially the one linking ring C with ring D. This work reports on the chemical synthesis and biological evaluation of thirteen new cystobactamids that still contain the methoxyaspartate hinge. However, we exchanged selected amide bonds either by the urea or the triazole groups and modified ring A in the latter case. While hydrolytic stability could be improved with these structural substitutes, the high antibacterial potency of cystobactamid 861-2 could only be preserved in selected cases. This includes derivatives, in which the urea group is positioned between rings A and B and where the triazole is found between rings C and D.

description: Grinding tools with superabrasive grains can be manufactured from different bond materials. In several industrial applications, metallic bond systems are used. In general, these show good grain retention and offer a high thermal conductivity, when compared to the other widely used bond types such as vitrified and resin bonds. One drawback of the metallic bond is the lack of pores in the grinding layer. This is caused by the manufacturing processes that are typically used, like brazing or hot pressing. These generally produce very dense layers. The high density and low porosity lead to comparatively little space for the transport of lubricant, coolant, and chips. One approach to eliminate this disadvantage is to introduce cavities into the grinding layer, using the laser powder bed fusion technique (LPBF). In order to evaluate the general suitability of LPBF in combination with the bond material and diamond grains, grinding layer samples with a nickel-titanium bond were produced. The abrasive behavior of these samples was tested in scratch tests on cemented carbide to verify the applicability as grinding tools. While the diamond grains in the powder mixture are not part of the fusion process, they also did not interfere with the manufacturing process, and the scratch tests showed promising abrasive capabilities. The grinding layer itself withstood the process forces, and no grain breakout could be observed. This indicates that the grain retention forces are high enough for the grinding process and that NiTi has a high potential as a bonding material for the manufacturing of grinding tools via LPBF.

description: Glaucoma is a neurodegenerative disorder marked by the death of retinal ganglion cells and cupping of the optic nerve head, both of which cause vision fiel loss. Glaucoma remains the leading cause of irreversible blindness worldwide. The only well established modifiable risk factor is intraocular pressure (IOP). When the glaucome is refractory to medical treatment, surgery is considered. Over the last decade, surgical options for glaucoma management have been augmented with the introduction of minimally invasive glaucoma surgery (MIGS). The Preserflo Microshunt ( Santen, Osaka, Japan) formerly known as the InnFocus Microshunt, is a novel MIGS that facilitates aqueous humor drainage to a sub-Tenon's bleb created ab-externo with the aime of providing meaningful intraocular pressure reduction with improved safety than gold-standard glaucoma filtration surgery. This systematic review evaluate the efficacy and safety of the Microshunt Preserflo versus trabeculectomy or XEN gel stent in open angle glaucoma. Inclusion studies: comparative studies between Preserflo versus trabeculectomy and/or XEN Gel Stent implantation with data about intra-ocular pressure reduction ( IOP pre and post surgery). Exclusion studies: case reports, conference abstracts, in vitro studies, numerical model studies, animal studies , sigle-arm studies, less than 3 months follow up studies.
Stochastic analysis of the time evolution of Laminar-Turbulent bands of plane Couette flow

description: This article is concerned with the time evolution of the oblique laminar-turbulent bands of transitional plane Couette flow under the influence of turbulent noise. Our study is focused on the amplitude of modulation of turbulence. In order to guide the numerical study of the flow, we first perform an analytical and numerical analysis of a Stochastic Ginzburg-Landau equation for a complex order parameter. The modulus of this order parameter models the amplitude of modulation of turbulence. Firstly, we compute the autocorrelation function of said modulus once the band is established. Secondly, we perform a calculation of average and fluctuations around the exponential growth of the order parameter. This type of analysis is similar to the Stochastic Structural Stability Theory. We then perform numerical simulations of the Navier-Stokes equations in order to confront these predictions with the actual behaviour of the bands. Computation of the autocorrelation function of the modulation of turbulence shows quantitative agreement with the model: in the established band regime, the amplitude of modulation follows an Ornstein-Uhlenbeck process. In order to test the S3T predictions, we perform quench experiments, sudden decreases of the Reynolds number from uniform turbulence, in which modulation appears. We compute the average evolution of the amplitude of modulation and the fluctuations around it. We find good agreement between numerics and modeling. The average trajectory grows exponentially, at a rate clearly smaller than that of the formation of laminar holes. The actual time evolution remains in a flaring envelope, centred on the average, and expanding at the same rate. These results provide further validation of the stochastic modeling for the time evolution of the bands for further studies. They stress on the difference between the oblique band formation and the formation of laminar holes.

description: The ordered hexagonal perovskite Ba2CuTeO6 hosts weakly coupled S=1/2 spin ladders produced by an orbital ordering of Cu2+. The magnetic susceptibility chi(T) of Ba2CuTeO6 is well described by that expected for isolated spin ladders with exchange coupling of J~86 K but shows a deviation from the expected thermally activated behavior at low temperatures below T*~25 K. An anomaly in chi(T), indicative of magnetic ordering, is observed at T_mag=16 K. No clear signature of long-range ordering, however, is captured in NMR, specific heat or neutron diffraction measurements at and below T_mag. The marginal magnetic transition, indicative of strong quantum fluctuations, is evidence that Ba2CuTeO6 is in very close proximity to a quantum critical point between a magnetically ordered phase and a gapped spin liquid controlled by inter-ladder couplings.

description: We performed inelastic neutron scattering experiments on Cu$_2$$^{114}$Cd$^{11}$B$_2$O$_6$ powder. The magnetic excitations at low temperatures are similar to those of the interacting spin-1/2 tetramers in the ordered state. The weak excitations existing above 3 meV suggest that the Higgs mode appears in Cu$_2$CdB$_2$O$_6$ at ambient pressure and zero magnetic field. We evaluated $J_1 = 27.3 \pm 1.0$ and $J_2 = -14.0 \pm 1.4$ meV for the intra-tetramer interactions and $J_3 = -0.4 \pm 0.2$ and $J_4 = 1.4 \pm 0.2$ meV for the inter-tetramer interactions. The spin gap in the isolated spin tetramer was calculated to be 1.6 meV, which is less than the effective inter-tetramer interaction value ($3.6 \pm 0.8$ meV). Therefore, antiferromagnetic long-range order is possible, although the ground state of the isolated spin tetramer is the spin-singlet state. We discuss the temperature dependence of the magnetic excitations.

description: Struthiopteris spicant var. fallax (Lange) Wasowicz & Gabriel y Galán, comb. nov.
 Basionym: Blechnum spicant var. fallax Lange (1880: 11–12).
 Lectotype (designated by Wasowicz et al. 2017):— ISLAND. Tunguhver, varme Kilde, Ch. GrØnlund s.n. (C! barcode C 10021769, left hand specimen, ”no. 2” and its separate parts).
 Notes:— Plants classified to the var. fallax are very small, with monomorphic leaves 2–5 cm long. All leaves in this taxon are fertile and in shape similar to the sterile ones in var. spicant. Variety fallax was first discovered by Danish botanist Christian Grønlund during his excursion to Iceland in 1876 (Grønlund 1881). He found the plant growing on the cone of a large hot spring called Deildartunguhver in western Iceland. Grønlund passed his herbarium material to Lange (Löve & Löve 1966), who described var. fallax on the basis of these collections (Lange 1880). During summer 2016 all locations of plants previously classified as var. fallax were visited by the authors. This study proved that var. fallax is still present only in one locality (locus classicus) where it forms a large population of several hundred individuals that are morphologically uniform and conform to the description of var. fallax given by Lange. In the vicinity of all other hot springs the presence of typical, heterophyllous var. spicant was confirmed. No transition forms to var. spicant were observed.

description: There are many ways to decompose the Hilbert space H of a composite quantum system into tensor product subspaces. Different subsystem decompositions generally imply different interaction Hamiltonians V, and therefore different expectation values for subsystem observables. This means that thE uniqueness of physical predictions is not guaranteed, despite the uniqueness of the total Hamiltonian H and the total Hilbert space. Here we use Clausius' version of the second law of thermodynamics (CSL) and standard identifications of thermodynamic quantities to identify possible subsystem decompositions. It is shown that agreement with the CSL is obtained, whenever the total Hamiltonian and the subsystem-dependent interaction Hamiltonian commute (i.e. [H,V]=0). Not imposing this constraint can result in the transfer of heat from a cooler to a hotter subsystem, in conflict with thermodynamics. We also investigate the status of the CSL with respect to non- standard definitions of thermodynamic quantities and quantum subsystems.

description: In this paper, we consider two regularized transformation-optics cloaking schemes for electromagnetic (EM) waves. Both schemes are based on the blowup construction with the generating sets being, respectively, a generic curve and a planar subset. We derive sharp asymptotic estimates in assessing the cloaking performances of the two constructions in terms of the regularization parameters and the geometries of the cloaking devices. The first construction yields an approximate full-cloak, whereas the second construction yields an approximate partial-cloak. Moreover, by incorporating properly chosen conducting layers, both cloaking constructions are capable of nearly cloaking arbitrary EM contents. This work complements the existing results in [5--7] on approximate EM cloaks with the generating set being a singular point, and it also extends [9,25] on regularized full and partial cloaks for acoustic waves governed by the Helmholtz system to the more challenging EM case governed by the full Maxwell system.

description: This thesis presents a conceptualization of Arendtian imagination that emerges from an analysis of some of Hannah Arendt's most significant writings. Imagination, on this account, is central to the processes of Arendtian action and Arendtian judgment, insofar as it enables the actor and spectator to imagine a new world that either could look (for the actor) or could have looked (for the spectator) differently from the world that either exists (for the actor) or existed (for the spectator). Importantly, though, the imagined world that facilitates the processes of Arendtian action and Arendtian imagination cannot be so distinct from the world as it exists as to lose any touch with reality itself. Such loss of reality risks actions that are destructive and tyrannical and judgments that are invalid and inattentive. Imagination must be bounded, then, to ensure that the imagined worlds remain close to reality.

description:
 The widespread use of digital resources, the Internet and the
 development of technology have brought several significant changes in
 reading practices, preferences and use among information consumers.
 Readers of the 21st century have many options for reading thanks to the
 rapid growth of electronic-based reading materials, instead of printed ones,
 such as online newspapers, electronic books, digital encyclopedias, and
 online academic journals, as well as the expansion of e-book readers. All
 of these have contributed to changing readers’ reading strategies, reading
 preferences, and attitudes toward the act of reading. In the field of
 academia, for instance, there has been a tremendous shift from paper-based
 reading to screen-based reading. Given the fact that digital devices have
 become pervasive, and that reading has recently become a digital activity,
 this article proposes the need to investigate the impact of print vs. digital
 reading materials on Moroccan undergraduate students’ reading behaviors,
 preferences and use.

description: Ionization injection is attractive as a controllable injection scheme for generating high quality electron beams using plasma-based wakefield acceleration. Due to the phase dependent tunneling ionization rate and the trapping dynamics within a nonlinear wake, the discrete injection of electrons within the wake is nonlinearly mapped to discrete final phase space structure of the beam at the location where the electrons are trapped. This phenomenon is theoretically analyzed and examined by three-dimensional particle-in-cell simulations which show that three dimensional effects limit the wave number of the modulation to between $> 2k_0$ and about $5k_0$, where $k_0$ is the wavenumber of the injection laser. Such a nano-scale bunched beam can be diagnosed through coherent transition radiation upon its exit from the plasma and may find use in generating high-power ultraviolet radiation upon passage through a resonant undulator.

description: Low-mass dwarf galaxies are very sensitive test-beds for theories of cosmic structure formation since their weak gravitational fields allow the effects of the relevant physical processes to clearly stand out. Up to now, no unified account exists of the sometimes seemingly conflicting properties of the faintest isolated dwarfs in and around the Local Group, such as Leo T and the recently discovered Leo P and Pisces A systems. Using new numerical simulations, we show that this serious challenge to our understanding of galaxy formation can be effectively resolved by taking into account the regulating influence of the ultraviolet radiation of the first population of stars on a dwarf's star formation rate while otherwise staying within the standard cosmological paradigm for structure formation. These simulations produce faint, gas-dominated, star-forming dwarf galaxies that lie on the baryonic Tully-Fisher relation and that successfully reproduce a broad range of chemical, kinematical, and structural observables of real late-type dwarf galaxies. Furthermore, we stress the importance of obtaining properties of simulated galaxies in a manner as close as possible to the typically employed observational techniques.

Conclusion and Future Recommendation

Publisher: name: A+BE | Architecture and the Built Environment

description: Interactive Architecture should embody the features of “Information”, “Improvisation”, and “Integration” in order to generate sufficient “Intelligence” to embody the authentic kernel of “Organic Architecture”. In the domain of Interactive Architecture, it is quite easy to become trapped in discussions predominantly focused on technical discourses. This is what can be observed in most of the published materials on Interactive Architecture available in the market today. These publications draw too much attentions in the manner of how to make technical systems, instead of focusing on why to make it. Partly, this may be because it is necessary to understand hands-on technical issues, however, there should certainly be more informative material to fertilize design thinking of Interactive Bio-Architecture. Some other publications in the same genre fall into a collection of on-going case studies in the domain of Interactive Architecture without properly arranging them into an organized systemic discourse. Unlike such publications, this research attempts to become a pioneering exploration attempting to address Interactive architecture as the convergence of three areas: Computation, Embodiment (Body), and Biology. From the computational point of view, the research outlined the historic trajectory of computational applications in digital architecture design or CAAD (computer aided architectural design) and its evolution from data storage, rendering representation, towards sophisticated physical computing. From embodiment(body) perspective, a wide range of issues from diverse fields of metrology, philosophy, media studies, interactive art, VR and motion tracking technology have been elaborated upon in order to discover intimate relationships and connections between (cyber)space and (cyborgs)human. In the section of Biology, the discussion ranged from the so-called organic architecture design that remains at the stage of mimicking organic shapes, to extracting and translating the fundamental premises of morphogenesis from Evolutionary-Development Biology (Evo-Devo) in order to propose computationally assisted body-like interactive Bio-architectures. By leading the arguments slightly more towards the humanities, cultural, and social or even biological aspects, it aims to broaden the research scope of Interactive Bio-Architecture to reverse its stereotypical associations of being extremely technical and engineering oriented. This research thus concludes by providing critical emphasis on topics such as Information, Improvisation, Integration, and Intelligence, which are reflective of the fundamental essence of the inter-disciplinary research elaborated in each chapter of the thesis.

description: The SHGH conjecture proposes a solution to the question of how many conditions a general union of fat points imposes on the complete linear system of curves in $\mathbb P^2$ of fixed degree $d$, and it is known to be true in many cases. We propose a new problem, namely to understand the number of conditions imposed by a general union of fat points on the incomplete linear system defined by the condition of passing through a given finite set of points $Z$ (not general). Motivated by work of Di Gennaro-Ilardi-Vallès and Faenzi-Vallès, we give a careful analysis for the case where there is a single general fat point, which has multiplicity $d-1$. There is an expected number of conditions imposed by this fat point, and we study those $Z$ for which this expected value is not achieved. We show, for instance, that if $Z$ is in linear general position then such unexpected curves do not exist. We give criteria for the occurrence of such unexpected curves and describe the range of values of $d$ for which they occur. Unexpected curves have a very particular structure, which we describe, and they are often unique for a given set of points. In particular, we give a criterion for when they are irreducible, and we exhibit examples both where they are reducible and where they are irreducible. Furthermore, we relate properties of $Z$ to properties of the arrangement of lines dual to the points of $Z$. In particular, we obtain a new interpretation of the splitting type of a line arrangement. Finally, we use our results to establish a Lefschetz-like criterion for Terao's conjecture on the freeness of line arrangements.

description: We investigate matter couplings in massive bigravity. We find a new family of such consistent couplings, including and extending known consistent matter couplings, and we investigate their decoupling limits, ADM decompositions, Higuchi bounds and further aspects. We show that differences to previous known consistent couplings only arise beyond the $Λ_3$ decoupling limit and discuss the uniqueness of consistent matter couplings and how this is related to the so-called symmetric vielbein condition. Since we work in a vielbein formulation, these results easily generalise to multi-gravity.

description: We show that the honeycomb Heisenberg antiferromagnet with $J_1/2=J_2=J_3$, where $J_{1/2/3}$ are first-, second- and third-neighbour couplings respectively, forms a classical spin liquid with pinch-point singularities in the structure factor at the Brillouin zone corners. Upon dilution with non-magnetic ions, fractionalised degrees of freedom carrying $1/3$ of the free moment emerge. Their effective description in the limit of low-temperature is that of spins randomly located on a triangular lattice, with a frustrated interaction of long-ranged logarithmic form. The XY version of this magnet exhibits nematic thermal order by disorder, which comes with a clear experimental diagnostic.

Density shock waves in confined microswimmers

description: Motile and driven particles confined in microfluidic channels exhibit interesting emergent behavior from propagating density bands to density shock waves. A deeper understanding of the physical mechanisms responsible for these emergent structures is relevant to a number of physical and biomedical applications. Here, we study the formation of density shock waves in the context of an idealized model of microswimmers confined in a narrow channel and subject to a uniform external flow. Interestingly, these density shock waves exhibit a transition from `subsonic' with compression at the back to `supersonic' with compression at the front of the population as the intensity of the external flow increases. This behavior is the result of a non-trivial interplay between hydrodynamic interactions and geometric confinement, and is confirmed by a novel quasilinear wave model that properly captures the dependence of the shock formation on the external flow. These findings can be used to guide the development of novel mechanisms for controlling the emergent density distribution and average population speed, with potentially profound implications on various processes in industry and biotechnology such as the transport and sorting of cells in flow channels.
The Impact of Reading Medium on the Comprehension and Judgment of Performance of Moroccan EFL Readers

description: Technology use in Moroccan higher education classrooms is growing at an exponential rate. However, current knowledge about the pedagogical effectiveness of Information Communication Technology (ICT) usage for reading and self-efficacy beliefs of Moroccan EFL readers is inconclusive. The main purpose of the present study was to examine the impact of reading texts on paper versus on-screen on reading comprehension and judgment of performance, while controlling for relevant individual difference variables. In a between-subjects design, three groups of first-year university students (N = 83) read an expository text on a sheet of paper versus on a laptop. Before reading, topic knowledge was assessed. After reading, participants were asked to answer three open-ended questions (main idea, key points, and other relevant ideas) and one closed-ended question (true-false). Next, based on the medium used for reading, participants were asked to rate how confident they were that the answers they provided were correct. Results of the t-test showed that reading medium did not affect overall reading comprehension, but slight differences between groups emerged. Calculated means indicated that participants who read on paper scored somewhat better on the main idea and other-relevant ideas questions; whereas, participants who read on-screen scored a little bit better on the key points and true-false questions. Moreover, results suggested no influence of the reading medium on students’ post-task judgments, indicating that participants who read on-screen were about as accurate in judging their comprehension performance as those who read on paper. These results suggest that reading short factual texts on the screen has no detrimental effects on the cognitive and metacognitive abilitiesof EFL readers.

description: The 60s was the age of freedom and boldness. According to John Lennon, the legendary singer-songwriter, who said in his last interview for RKO, “The thing the sixties did was to show us the possibilities and the responsibility that we all had. It wasn’t the answer. It just gave us a glimpse of the possibility”.10 Various technologies and cultures were developing boundlessly at an unprecedented speed during this time. Movements for civil rights due to racial discrimination, movements for women’s rights due to feminism, liberation movements for bodily autonomy, and student movements (Mai 68) in France due to the education system, influenced and challenged the conservative thought and systems in the society which people were used to. With the flourishing development of high-end technology, during the cold war period, the US and Russia were still competing to be the world leaders in technological development. The battlefields of the well-known space race included not only the terrain of the earth but also the surface of the moon. For the general public, the impact of rapid technological development, plus the discovery of chaos theory in Science and the gradual advancement of computer technology, opened the door towards all kinds of imagination about how the future world will look. The influential pop art movement, gave new birth to art which was no longer bigwigs’ assets hung on the walls of a royal palace and high-end art galleries, but relatively closer to people’s daily lives by using common substances and materials for creating art pieces. In addition, with the growth of the underground hippy culture and rock ‘n roll music, it was the golden age when people gradually had the courage to explore, to experiment, to express personal opinions, and dare to imagine and expect a future life of their own. And this was also the time when Archigram was born.
