description: Unlike animals, plants express several CaM isoforms. A unique variant of calmodulin which bears a C-terminal prenylation site is present in some plant cells such as Oryza sativa and Petunia hybrida. In this thesis I demonstrated that the tail adopts a partial helical structure and that the tail interacts with different regions of the protein in the presence and absence of calcium. Altogether it seems that the tail represents a new regulatory mechanism that plants can utilize to control calcium signalling. Another interesting aspect of calcium signalling are the plant-specific calcium-ATPases and their interactions with calmodulin. In this thesis the structure of soybean calmodulin isoform 4 (sCaM4) in complex with ACA2 and ACA8, which belong to two different groups of calcium-ATPases, were examined. Altogether it seems that the CaM-binding domain of different calcium-ATPases with different locations in the cell have unique structural characteristics, which leads to distinct regulation by sCaM4.

description: By means of catalytic chemical vapor deposition (CCVD) in-situ grown monolayer graphene field-effect transistors (MoLGFETs) and bilayer graphene transistors (BiLGFETs) are realized directly on oxidized silicon substrate without the need to transfer graphene layers. In-situ grown MoLGFETs exhibit the expected Dirac point together with the typical low on/off-current ratios. In contrast, BiLGFETs possess unipolar p-type device characteristics with an extremely high on/off-current ratio up to 1E7. The complete fabrication process is silicon CMOS compatible. This will allow a simple and low-cost integration of graphene devices for nanoelectronic applications in a hybrid silicon CMOS environment.

“Litterarum plane rudis sed ingenii acumine adeo praestans”: impalcati per la manutenzione dell’architettura nella Roma settecentesca tra pratica artigianale, sperimentazione tecnica e codifica teorica
Creators: name: Marconi, Nicoletta
Publisher: name: Opus Incertum

description: Renaissance and Baroque building machines and construction techniques have been widely explored in the scientific literature, but scaffoldings for ordinary and extraordinary maintenance remain less well-documented, and were rarely part of architectural treatises. This is because on the building sites of the early modern age the construction of scaffolding was entrusted to the experience of craftsmen like bricklayers and carpenters. Nicola Zabaglia (1667-1750) was a master carpenter of the Fabbrica of St. Peter’s and, exceptionally, his astonishing inventions and those of his successors were considered virtuoso examples of operational empiricism and were included in the main European treatises on construction up until the early 20th century. Their long-lasting fortune shows that the scientific method did not make the empirical approach obsolete, but a gradual incorporation of theoretical precepts sanctioned the successful qualitative transition in the relationship between theory and practice even on the construction site.

Les termes liégeois et français dans l’architecture domestique à Liège au XVIIIe siècle : l’exemple du vocabulaire de la cheminée
Creators: name: Gilles, Isabelle
Publisher: name: Opus Incertum
Year: 2020

description: This article first discusses the change in technical terminology of domestic architecture in Liège in the course of the 18th century, which saw an increasing appropriation of French words originating from Paris and a progressive disappearance of the local, Walloon vocabulary − the memory of which is preserved in the first Walloon-French Dictionary, published in 1787 by the Liège ecclesiastic Remi-HenriJoseph Cambresier. It then examines more closely the case of the domestic chimneypiece, as this illustrates the use of a vocabulary that was distinctive to Liège, where coal was customarily employed for domestic purposes (heating and cooking), resulting in a terminology that had no equivalent in the French language but was subsequently exported to Paris, particularly through the writings of the French physician Jean-François-Clément Morand (1726-1784).

description: We study the pathologies in AdS black branes in Lovelock theory. More precisely, we examine the conditions that AdS black branes have the naked singularity, the ghost instability and the dynamical instability. From the point of view of the AdS/CFT correspondence, the pathologies in AdS black branes indicate the pathologies in the corresponding CFT. Hence, we need to be careful when we apply AdS/CFT in Lovelock theory to various phenomena such as the shear viscosity to entropy ratio in strongly coupled quantum filed theory.

Three-parton contribution to the $B\toπ$ form factors in $k_T$ factorization

description: We calculate the three-parton twist-3 contribution to the $B\toπ$ transition form factors in the $k_T$ factorization theorem. Since different mesons are involved in the initial and final states, two(three)-parton-to-three(two)-parton amplitudes do not vanish. It is found that the dominant contribution arises from the diagrams with the additional valence gluon attaching to the leading-order hard gluon. Employing the three-parton meson distribution amplitudes from QCD sum rules, we show that this subleading piece amounts only up to few percents of the form factors at large recoil of the pion. The framework for analyzing three-parton contributions to $B$ meson decays in the $k_T$ factorization is established.

description: We study the fine tuning in the parameter space of the semi-constrained NMSSM, where most soft Susy breaking parameters are universal at the GUT scale. We discuss the dependence of the fine tuning on the soft Susy breaking parameters M_1/2 and m0, and on the Higgs masses in NMSSM specific scenarios involving large singlet-doublet Higgs mixing or dominant Higgs-to-Higgs decays. Whereas these latter scenarios allow a priori for considerably less fine tuning than the constrained MSSM, the early LHC results rule out a large part of the parameter space of the semi-constrained NMSSM corresponding to low values of the fine tuning.

Predicting Post-Operative Functional Performance, Treatment Path, and Overall Survival in Glioblastoma Patients based on Tumour Location and Size

description: Glioblastoma multiforme (GBM) is the most common primary brain malignancy in adults with a median survival of 12-18 months with treatment. Surgical reduction of the tumour volume by 78% or more increases patient life expectancy (further extended by adjuvant radio/chemotherapy). Although GBM surgery focuses on complete removal of the tumour, there is limited evidence supporting the approach, and the question of what effect the extent-ofresection (EOR) has on patient prognosis is frequently asked. Furthermore, extensive surgery in GBM management has been associated with surgically-acquired motor and language deficits. In addition, present subjective appraisals of tumour severity based on location are inconsistent. Working towards an objective grading system with radiological markers has been suggested to improve accuracy. In this thesis, I demonstrate a quantitative approach for assessing tumour severity. These results provide more evidence for tumour anatomical location and size as factors in affecting post-surgical functional performance and predicting clinical response.
The Origin of Force Increase in Actively Stretched Single Muscle Fibres

Subjects: subject: Physiology

subject: muscle contraction
subject: residual force enhancement

description: Theoretically, at long sarcomere lengths (SLs) beyond myofilament overlap, only passive forces, produced by passive structural elements, are possible. However, previous studies showed a dramatic increase in force above the passive force when myofibrils were actively stretched beyond actin and myosin filament overlap. It has been suggested that titin might produce this increase in force, possibly by increasing its stiffness in a variety of ways. In this study, I used rabbit psoas single muscle fibres to investigate whether the increase in force observed after active stretch to a sarcomere length beyond myofilament overlap was caused by a passive component (titin) alone, or possibly some remnant cross-bridges that continue to contribute force in some unknown manner in muscle fibres. The results indicate that both passive and active components are contributing to this force increase in actively stretched single muscle fibres at an average sarcomere length beyond myofilament overlap.
Sparkles under the Northern Sun: The Danckerts Press and the Slow Introduction of Writing on Building Technique in the Dutch Republic
Creators: name: Goudeau, Jeroen
Publisher: name: Opus Incertum
Year: 2020

description: Between 1630 and 1727 the rich catalogue of the Danckerts press covered a wide span of subjects in contemporary architecture. This case-study makes clear that in the Dutch Republic the interest in autonomous information on building techniques arose relatively late. Publishers mostly looked to Italy, France and, as is demonstrated here, also to Germany. In the genres discussed, actual building techniques can only be traced to a very limited extent. It is more precise to speak of technical details in the communication of architecture. Only in 1680 the first book with exclusively technical illustrations appeared, Architectura chivilis, based on a German source. Danckerts proved to be a pioneer in what would become an independent technical book genre. Around 1700, books on elements of civil architecture, such as roofs and stairs, were accompanied by publications on mills, sluices, and bridges. It was only then that building techniques in the strict sense found their way into books.

We verify this relation by extensive numerical calculations. We also demonstrate that the level compressibility $χ$ describing level correlations can be related to $D_q$ in a unified way as $D_q=(1-χ)[1+(q-1)χ]^{-1}$, thus generalizing existing relations with relevance to the disorder driven Anderson--transition.

description: The purpose of this study was to explore the phenomenon of special education teachers and child and youth care workers’ (CYCWs) individual and collective experiences integrating new mobile (iPad) technologies into their daily practices in a rural, alternate educational setting in British Columbia, Canada. The research used an exploratory, holistic, single-case study framed by Rogers’ Diffusion of Innovation (DOI) theory. Data was collected using six procedures: open-ended technology and iPad technology questionnaires; semi-structured focus group interviews; semi-structured individual interviews; observations; reflective memos; and reflective journals. Preliminary exploratory analysis; inductive data analysis; constant comparative methods of analysis; descriptive tables; concept mapping; and thematic charting were the qualitative data analysis techniques used to develop a coding system, to draw out key themes, and to interpret the findings. This study identified key factors influencing participants’ readiness to use iPads, current practices with these devices, conditions that enabled the use of iPads, and barriers to the use of these devices in alternate educational settings. The findings suggest that with ongoing, targeted professional development for educators that teaches them how to use technologies to support their teaching practices within their subject area, and regular opportunities and time to participate in collaborative conversations about technology integration, iPads could be integrated into classrooms in a sustainable way that enhances instruction and student learning. Additional research needs to address the gap between theory and practice, which suggests that teachers do not know how to effectively use iPads with students in ways that enhance students’ learning experiences and provide authentic, engaging learning activities.

Finally, we give some conditions in which the Baer invariant of a triple is a torsion group.

description: Even in his own time, Philippe de La Hire (1640–1718) was known as a prolific and accomplished mathematician and scientist with an insatiable curiosity. A member of the Académie des sciences (since 1678) and professor at the Collège Royal (since 1682), in 1687 he became the second professor (after François Blondel) at the Académie royale d’architecture, even though he never built anything. In this academy, he was very active and presented several contributions on the architectural orders, shared his own translation of Scamozzi’s L’idea della architettura universale, and held several courses for the future architects of the king on geometry, optics, stereotomy and architecture. He presented his course on architecture three times (1698-1699, 1705-1706, 1714-1715); it is preserved in three manuscript versions (in Paris, London, and Einsiedeln), covers construction, hydraulics, orders, interior distribution, etc., and can be considered the first general manual on architecture in France. La Hire developed his own propositions on construction. He commented on theoretical texts, studied buildings from antiquity and of his own time, and always and more than other theoreticians, gave great importance to arithmetic and geometry.

description: Preliminary specifications for the Square Kilometre Array (SKA) call for 25% of the total collecting area of the dish array to be located at distances greater than 180 km from the core, with a maximum baseline of at least 3000 km. The array will provide angular resolution ~ 40 - 2 mas at 0.5 - 10 GHz with image sensitivity reaching < 50 nJy/beam in an 8 hour integration with 500 MHz bandwidth. Given these specifications, the high angular resolution component of the SKA will be capable of detecting brightness temperatures < 200 K with milliarcsecond-scale angular resolution. The aim of this article is to bring together in one place a discussion of the broad range of new and important high angular resolution science that will be enabled by the SKA, and in doing so, address the merits of long baselines as part of the SKA. We highlight the fact that high angular resolution requiring baselines greater than 1000 km provides a rich science case with projects from many areas of astrophysics, including important contributions to key SKA science.

description: We present a microscopic computation of the radio emission from air showers initiated by ultra-high energy cosmic rays in the atmosphere. The strategy adopted is to compute each secondary particle contribution of the electromagnetic component and to construct the total signal at any location. SELFAS2 is a code which doesn't rely on air shower generators like AIRES or CORSIKA and it is based on the concept of air shower universality which makes it completely autonomous. Each positron and electron of the air shower is generated randomly following relevant distributions and tracking them along their travel in the atmosphere. We confirm in this paper earlier results that the radio emission is mainly due to the time derivative of the transverse current and the time derivative of the charge excess. The time derivative of the transverse current created by systematic deviations of charges in the geomagnetic field is usually dominant compared to the charge excess contribution except for the case of an air shower parallel to the geomagnetic field.

Returning to Vimy Ridge : Canada's narrative of battle and remembrance
Creators: name: Lermitte, Janet L.
Publisher: name: University of British Columbia
Year: 2010

description: The approach of the centennial of World War I (1914-1918) has marked an increase in domestic and international interest in war narratives. In Canada, this can be most clearly seen in the institutional focus on remembering Canada's first major military victory in that war, the Battle of Vimy Ridge. This study begins with the question of why the grand narrative of Vimy Ridge continues to persist in the national consciousness, especially as it relates to identity construction and commemorative practice. And why do Canadian artists, educators, historians and war veterans continue to return to Vimy? Through my examination of three texts that represent three different genres in Canadian literature, Pierre Berton's popular history book, Vimy, Jane Urquhart's novel The Stone Carvers, and Vern Thiessen's play, Vimy, I endeavour to make conclusions about the role of contemporary artists in challenging and disrupting traditional representations of the Vimy narrative. In particular, this study explores how these authors (especially Urquhart and Thiessen) are engaged in an imaginative retelling or revision of the meta-narrative or "myth" of Vimy. I employ Jonathan Vance's use of the term "myth" to capture the imaginative and epic elements of the Vimy story. At the same time, I examine specific ways in which Thiessen and Urquhart interrogate traditional representations of soldiers and the home front through their depictions of gender, ethnicity, religion and art. These two writers are exploring alternative narratives, or in the words of Herb Wyile, "speculative fictions" that unfold in the inventive blend of history and fiction. My field work at the site of Vimy Memorial Park near Arras, France, and at the Canadian War Museum in Ottawa, Ontario, also has as its focus the commemorative role of Vimy in national narratives about WWI. At these two sites, I found evidence of the institutional mandate to remember juxtaposed with the material evidence of social and cultural suffering and healing. My conclusions argue that the Vimy narrative continues to play an important role in the Canadian social ethos, but contemporary approaches to the narrative provide critical interventions to the representation of war in Canada.
L’apparition du traité technique au XVIe siècle en France et sa fortune au XVIIe siècle de Mathurin Jousse à Claude Perrault
Creators: name: Lemerle, Frédérique
Publisher: name: Opus Incertum
Year: 2020

description: The 17th century was a new era for architectural literature, in Europe and especially in France. Specialized technical writings, covering all branches of building, replaced general treatises. This new development was linked to the mass dissemination enabled by the printing press and to the mastery of engraving techniques, in particular intaglio printing. The renovation of Paris and some avant-garde construction sites in the provinces, and more generally the artistic policy of the French monarchy, stimulated an architectural production in which technical treatises feature prominently. Examples include those of Mathurin Jousse on carpentry and stereotomy (1627 and 1642), François Derand on stereotomy (1642), and Abraham Bosse, who published Girard Desargues’ works (1643). All these books, as well as the composite ones which deal in detail with certain practical aspects of construction (Le Muet, 1623 and 1645), reveal the close relationship between theory and architectural practice, tradition and modernity, science and technique, as well as the occasional conflicts between architects and master builders.

description: A trivial projective change of a Finsler metric $F$ is the Finsler metric $F + df$. I explain when it is possible to make a given Finsler metric both forward and backward complete by a trivial projective change. The problem actually came from lorentz geometry and mathematical relativity: it was observed that it is possible to understand the light-line geodesics of a (normalized, standard) stationary 4-dimensional space-time as geodesics of a certain Finsler Randers metric on a 3-dimensional manifold. The trivial projective change of the Finsler metric corresponds to the choice of another 3-dimensional slice, and the existence of a trivial projective change that is forward and backward complete is equivalent to the global hyperbolicity of the space-time.

description: The prevalence of older adults with advanced chronic kidney disease (CKD) is increasing globally, although optimal treatment remains uncertain. We examined in this thesis survival outcomes for older adults with kidney failure treated and not treated with dialysis. We also sought to identify barriers and facilitators to optimal conservative (non-dialysis) care for older adults with kidney failure managed by primary care physicians. We conducted three studies: a population-based retrospective cohort study using administrative and laboratory data to compare survival outcomes between dialysis and non-dialysis treatment; a qualitative descriptive study to explore primary care physician experiences when providing conservative care to older adults with kidney failure; and a cross-sectional population-based survey study within Alberta, Canada, to quantify results from the previous qualitative study. These last two studies formed a sequential exploratory mixed methods program of work to identify barriers and facilitators to community-based conservative care. We found that compared to non-dialysis care, dialysis was associated with a reduced risk of all-cause mortality but only within the first three years following onset of kidney failure. Conservative care for older adults is commonly provided by primary care physicians; however, they face substantial barriers to optimal care. Primary care physicians also expressed a need for resources including telephone access to nephrology or conservative care expertise, better access to conservative care clinics, and improved ability to appropriately co-manage patients with nephrologists. Research in conservative care has previously focused on patients with advanced CKD referred to nephrology. However, conservative care and outcomes among older adults not referred to nephrology is largely unknown. This thesis examined clinical care and outcomes through a wider perspective. To foster clinical impact we worked closely from conceptualization to dissemination stages with key stakeholders in Alberta including the Southern Alberta Conservative Management Program, the Conservative Kidney Management Pathway Steering Committee, the Kidney Health Strategic Clinical Network, and the Alberta College of Family Physicians. Our findings contributed to development of a conservative kidney management clinical care pathway and province-wide telephone access for primary care physicians to directly contact nephrologists and conservative care specialists.

description: Perinatal stroke results in lifelong unilateral motor impairment. Periventricular venous infarct (PVI) is a subcortical injury sustained in utero whereas arterial ischemic stroke (AIS) occurs near term birth and often damages the primary motor cortex (M1). Both disease-states result in the maladaptive emergence of aberrant ipsilateral (M1’) connections. Task-based functional magnetic resonance imaging defined patterns of motor cortex activity during unilateral tapping of the paretic and non-paretic hand. Peak bilateral coordinates of M1 and M1’ were compared to controls. AIS cases displayed the greatest extent of M1 displacement in the lesioned hemisphere, but M1 displacement in PVI cases approximated controls. For stroke cases with bilateral control of their paretic hand, M1’ responses in the intact hemisphere were displaced from the canonical hand knob. We conclude that extensive motor reorganization occurs bilaterally following perinatal stroke. Targeting individualized M1 and M1’ displacements may facilitate opportunities for precision medicine in pediatric neurorehabilitation.

Bubbles in the new catalogue have been independently measured by at least 5 individuals, producing consensus parameters for their position, radius, thickness, eccentricity and position angle. Citizen scientists - volunteers recruited online and taking part in this research - have independently rediscovered the locations of at least 86% of three widely-used catalogues of bubbles and H ii regions whilst finding an order of magnitude more objects. 29% of the Milky Way Project catalogue bubbles lie on the rim of a larger bubble, or have smaller bubbles located within them, opening up the possibility of better statistical studies of triggered star formation. Also outlined is the creation of a 'heat map' of star-formation activity in the Galactic plane. This online resource provides a crowd-sourced map of bubbles and arcs in the Milky Way, and will enable better statistical analysis of Galactic star-formation sites.

description: This paper focuses on the representation of épures —the 1:1-scale geometric drawings necessary for the production of stereotomic works — in Philibert de L’Orme’s Premier tome de l’architecture (Paris 1567). Épures are technical drawings that medieval and early modern practitioners developed in order to solve the geometric challenges posed by stereotomy. Épures are traced on site and have functions similar to those of modern blueprints: they are produced by the appareilleur (setter) to communicate the geometry of the vault and its components (the voussoirs) to all the craftsmen involved in its making — those who prepare the templates, the carpenters who produce the centering, and the stonecutters who shape the voussoirs — and they are referred to throughout the execution process. Reading épures is a complex task for non-practitioners, and one that architectural historians have largely shunned, thus leaving a core aspect of de L’Orme’s theory of architecture unexplored. In this paper, I use the case study of the entrance to a descente de cave (inclined barrel vault), the simplest of stereotomic works illustrated by de L’Orme, to demonstrate how épures are produced and read.

description: We investigate transport in a three-terminal graphene quantum dot. All nine elements of the conductance matrix have been independently measured. In the Coulomb blockade regime accurate measurements of individual conductance resonances reveal slightly different resonance energies depending on which pair of leads is used for probing. Rapid changes in the tunneling coupling between the leads and the dot due to localized states in the constrictions has been excluded by tuning the difference in resonance energies using in-plane gates which couple preferentially to individual constrictions. The interpretation of the different resonance energies is then based on the presence of a number of levels in the dot with an energy spacing of the order of the measurement temperature. In this multi-level transport regime the three-terminal device offers the opportunity to sense if the individual levels couple with different strengths to the different leads. This in turn gives qualitative insight into the spatial profile of the corresponding quantum dot wave functions.

Distribution. * Estonia, * Finland, * Norway, * Sweden.—Transpalearctic: from Netherlands to Siberia (UsolyeSibirskoye). The general distribution is still poorly known, because many authors have confused E. foveatus with other closely related taxa.
Remarks. The species has been recently found from museum collections in Estonia, Finland, Norway and Sweden. Earlier it had been mixed with other species of Elampus. It is new to the Nordic and Baltic countries. Surprisingly, all but two specimens recorded so far have been females, although males are usually more commonly collected in Elampus.

Efficient Framework for Quantum Walks and Beyond

subject: quantum hitting time

description: In the first part of the thesis we construct a new, simple framework which amplifies to a constant the success probability of any abstract search algorithm. The total query complexity is given by the quantum hitting time of the resulting operator, which we show that it is of the same order as the quantum hitting time of the original algorithm. As a major application of our framework, we show that for any reversible walk $P$ and a single marked state, the quantum walk corresponding to $P$ can find the solution using a number of queries that is quadratically smaller than the classical hitting time of $P$. Our algorithm is more general and simpler to implement than the solution known previously in the literature (Krovi, Magniez, Ozols, and Roland, 2015), which was developed specifically for quantum walks; we also prove that, for the particular case of quantum walks, we can embed their algorithm into our framework, thus simulating it exactly. Finally, we show that we can implement amplitude amplification using our tool. In the second part of the thesis we give a new lower bound in the query model which proves that Grover's algorithm for unordered searching is exactly optimal. Similar to existing methods for proving lower bounds, we bound the amount of information we can gain from a single oracle query, but we bound this information in terms of angles. This allows our proof to be simple, self-contained, based on only elementary mathematics, capturing our intuition, while obtaining at the same an exact bound. We then turn our attention to non-adaptive algorithms for the same problem of searching an unordered set. In this model, we obtain a lower bound and we give an algorithm which matches the lower bound, thus showing that the lower bound is exactly optimal.
Légitimer le traité technique : la rhétorique de Philibert De l’Orme dans les Nouvelles inventions et le Premier tome

description: Philibert de L’Orme’s Nouvelles inventions pour bien bastir (1561), on carpentry, and books III and IV in his Premier tome de l’architecture (1567), on stereotomy, are the first printed texts dealing with purely technical questions. By publishing them, de L’Orme broke with the traditional methods used in the corporations to transmit technical skills: he incorporated the old oral know-how in the field of printed humanist culture. To legitimate this approach, he needed to use rhetorical techniques in his text. A precise narration explains how he presented his project to the king, and how Henry II ordered him to write a book on this subject. So he justified the publication of the Nouvelles inventions by a royal order, which protected him from the craftsmen’s criticisms. On the other hand, he presented an original allegory of the good architect in book III of the Premier tome, showing a new and prestigious aspect of the profession: the architect is no longer a mason, working in the field of the Aristotelian category of “art”, but also a humanist concerned with “prudence”: as such, he does not belong to the world of the corporations and may publish his works.

Reliability of complete gravitational waveform models for compact binary coalescences

description: With recent advances in post-Newtonian (PN) theory and numerical relativity (NR) it has become possible to construct inspiral-merger-ringdown waveforms by combining both descriptions into one hybrid signal. While addressing the reliability of such waveforms, previous studies have identified the PN contribution as the dominant source of error, which can be reduced by incorporating longer NR simulations. Here we overcome the two outstanding issues that make it difficult to determine the minimum NR simulation length necessary to produce suitably accurate hybrids: (1) the criteria for a GW search is the mismatch between the true waveform and a set of model waveforms, optimized over all waveforms in the model, but for discrete hybrids this optimization was not yet possible. (2) these calculations typically require that numerical waveforms already exist, while we develop an algorithm to estimate hybrid mismatches errors without numerical data. Our procedure relies on combining supposedly equivalent PN models at highest available order with common data in the NR regime, and their difference serves as a measure of the uncertainty assumed in each waveform. Contrary to some earlier studies, we estimate that ~10 NR orbits before merger should allow for the construction of waveform families that are accurate enough for detection in a broad range of parameters, only excluding highly spinning, unequal-mass systems. Nonspinning systems, even with high mass-ratio (q>=20) are well modeled for astrophysically reasonable component masses. The parameter bias is only of the order of 1% for total mass and symmetric mass-ratio and less than 0.1 for the dimensionless spin magnitude. We take the view that similar NR waveform lengths will remain the state of the art in the advanced detector era, and begin to assess the limits of the science that can be done with them.

Hard to Obtain, Hard to Translate: Lime and Earth Construction in Early Modern Portuguese Writings on Architecture and Fortification
Creators: name: Tavares Da Conceição, Margarida
Publisher: name: Opus Incertum
Year: 2020

description: Lime masonry and earthwork construction are subjects treated in the earliest written sources related to fortification in the Portuguese empire. Although these texts are not in the form of an architectural treatise, they do evince a noteworthy concern with construction techniques. A group of administrative records related to Mazagan (1541) provide us with a first-hand account regarding new methods of building a fortress, and reveal that good lime, considered more reliable than earth filling for the new ramparts, was difficult to obtain. Another source is an anonymous manuscript from around 1579, written by a fortificateur playing the role of the architect. Going beyond Vitruvian guidance, the author merges several sources with his own observations. A significant part of his text is devoted to construction techniques, including earthworks, and discusses new materials using new words that are sometimes hard to translate. Both cases show a pragmatic approach and a preference for time-tested knowledge and practical experimentation.

description: In Europe, cancer is the second leading cause of death from disease, behind only cardiovascular diseases. Research progress has been reported in scientific publications whose analysis has included bibliometric studies on the content and authorship of scientific activity with emphasis on gender participation. The aim of this work has been to evaluate the gender gap in Spanish cancer research over the las decade by analyzing the authorships in the derived publications and their correlation with respect to i) the integration of the sex and gender variable in the study carried out, and ii) the type of cancer investigated.
