title: APT: A principled design for an animated view of program execution for novice programmers
Creators: name: Rajan, Tim
Publisher: name: The Open University
Year: 1987

description: This thesis is concerned with the principled design of a computational environment which depicts an animated view of program execution for novice programmers. We assert that a principled animated view of program execution should benefit novice programmers by: (i) helping students conceptualize what is happening when programs are executed; (ii) simplifying debugging through the presentation of bugs in a manner which the novice will understand; (iii) reducing program development time. The design is based on principles which have been extracted from three areas: (i) the problems that novices encounter when learning a programming language; (ii) the general design principles for computer systems; and (iii) systems which present a view of program execution. The design principles have been embodied in three 'canned stepper displays for Prolog, Lisp and 6502 Assembler. These prototypes, called APT-0 (Animated Program Tracer), demonstrate that the design principles can be broadly applied to procedural and declarative; low and high level languages. Protocol data was collected from subjects using the prototypes in order to check the direction of the research and to suggest improvements in the design. These improvements have been incorporated in a real implementation of APT for Prolog. This principled approach embodied by APT provides two important facilities which have previously not been available, firstly a means of demonstrating dynamic programming concepts such as variable binding, recursion, and backtracking, and secondly a debugging tool which allows novices to step through their own code watching the virtual machine in action. This moves towards simplifying the novice's debugging environment by supplying program execution information in a form that the novice can easily assimilate. An experiment into the misconceptions novices hold concerning the execution of Prolog programs shows that the order of database search, and the concepts of variable binding, unification and backtracking are poorly understood. A further experiment was conducted which looked at the effect that APT had on the ability of novice Prolog programmers to understand the execution of Prolog programs. This demonstrated that the performance of subjects significantly increased after being shown demonstrations of the execution of Prolog programs on APT, while the control group who saw no demonstration showed no improvement. The experimental evidence demonstrates the potential of APT, and the principled approach which it embodies, to communicate run-time information to novice programmers, increasing their understanding of the dynamic aspects of the Prolog interpreter. APT, uses an object centred representation, is built on top of a Prolog interpreter and environment, and is implemented in Common Lisp and Zeta Lisp and runs on the Symbolics 3600 range of machines.

description: Erfahrungen aus verschiedenen Projekten zeigen: Geowissenschaften können von touristischer Vermarktung profitieren, umgekehrt kann auch der Tourismus von den Geowissenschaften profitieren. Eine solche Kooperation kann jedoch nur dann erfolgreich sein, wenn einige wichtige Voraussetzungen erfüllt sind. Der Gewinn (Win-Win-Situation) muss von beiden Seiten wahrgenommen werden. Insbesondere im Rahmen längerfristiger Kooperationen können Geowissenschaftler eine wirkungsvolle Marketing-Plattform, im Idealfall sogar neue, interessante Forschungsfelder, neue Lehr- und Lernorte und vielleicht sogar neue Drittmittelaufträge erhalten. Touristiker profitieren insbesondere von neuen, interessanten, innovativen und qualitativ hochwertigen Produkten und Angeboten. Beide Seiten können oftmals beträchtliche Kompetenzgewinne verbuchen. Eine effektive und effiziente Kooperation benötigt Vertrauen, das am besten im Kontext schnell umsetzbarer Starterprojekte entstehen und wachsen kann. Dabei geht es auch darum, das Bild des jeweils anderen Akteurskreises zu berichtigen. Geowissenschaftler haben das Image der trockenen Theoretiker, die sich mit etwas 'Kaltem', 'Totem' und 'Altem' beschäftigen. Touristiker haben eher das Image, dass sie "auf die Schnelle" ihre Landschaft vermarkten und "ohne Rücksicht auf Verluste" schnell Buchungszahlen und Gewinne sehen wollen. Eine Kooperation zwischen solch verschiedenartigen Akteurskreisen wie Touristikern und Geowissenschaftlern benötigt Kompromissbereitschaft auf beiden Seiten ...

description: One problem of the $Λ$CDM model is the tension between the $S_8$ found in Cosmic Microwave Background (CMB) experiments and the smaller one obtained from large-scale observations in the late Universe. The $σ_8$ quantifies the relatively high level of clustering. Bayesian Analysis of the Redshift Space Distortion (RSD) selected data set yields: $S_8 = 0.700^{+0.038}_{-0.037}$. The fit has $3σ$ tension with the Planck 2018 results. With Gaussian processes method a model-independent reconstructions of the growth history of matter in-homogeneity is studied. The fit yields $S_8 = 0.707^{+0.085}_{-0.085}, 0.701^{+0.089}_{-0.089}$, and $ 0.731^{+0.063}_{-0.062}$ for different kernels. The tension reduces and being smaller then $1.5\, σ$. With future measurements the tension may be reduced, but the possibility the tension is real is a plausible situation.

description: Visible light communication (VLC) systems are promising candidates for future indoor access and peer-to-peer networks. The performance of these systems, however, is vulnerable to the line of sight (LOS) link blockage due to objects inside the room. In this paper, we develop a probabilistic object detection method that takes advantage of the blockage status of the LOS links between the user devices and transceivers on the ceiling to locate those objects. The target objects are modeled as cylinders with random radii. The location and size of an object can be estimated by using a quadratic programming approach. Simulation results show that the root-mean-squared error can be less than $1$ cm and $8$ cm for estimating the center and the radius of the object, respectively.

title: Granitic Rocks of Ophiolites
Creators: name: Aldiss, Donald Tresham
Publisher: name: The Open University
Year: 1978

description: The field relationships, primary and secondary petrography and chemical composition of granitic rocks (plagiogranites) and associated formations in five ophiolites are described. In addition, the occurrence of similar rocks in other ophiolites, some island arcs and in the ocean crust is reviewed. Plagiogranites in ophiolites can be distinguished from all other granitic rocks by their almost complete lack of potassium feldspar, low alumina content, high K/Rb ratio and their LREdepleted, flat or "dished" rare earth profiles and negative europium anomalies. The hypothesis that ophiolites represent oceanic lithosphere fragments is supported by the strong resemblance of some granitic rocks d~edged from the seafloor to those in ophiolites. Granitic rocks in ophiolites differentiate from subalkaline tholeiitic magmas at spreading axes in mid-ocean and in marginal ocean basins. These magmas evolved on a trend of ironenrichment unless FeTioxides appeared as fractionating phases, which seems to have followed saturation of the magma by seawater. The magma then became progressively enriched in silica and sodium, evolving by the removal of plagioclase, FeTioxides, apatite and zircon. However, potassium was partitioned into the magmatic volatile phase and so entered the open hydrothermal system at the spreading axis and was thereby not enriched in the plagiogranites. Plagiogranites in ophiolites are all deuterically altered to assemblages typical or upper greenschist or lower amphibolite racies metamorphism. Hydrothermal activity in the vicinity or each magma cell beneath the spreading axis ceased soon after the last of the silicate liquid froze and there was little repenetration of the ophiolite plutonic complex by hydrothermal fluids.

description: We study the relativistic Vlasov-Maxwell system which describes large systems of particles interacting by means of their collectively generated forces. If the speed of light $c$ is considered as a parameter then it is known that in the Newtonian limit $c\to\infty$ the Vlasov-Poisson system is obtained. In this paper we determine the next order approximate system, which in the case of individual particles usually is called the Darwin approximation.

description: Topological fermions as excitations from multi-degenerate Fermi points have been attracting increasing interests in condensed matter physics. They are characterized by topological charges, and magnetic fields are usually applied in experiments for their detection. Here we present an index theorem that reveals the intrinsic connection between the topological charge of a Fermi point and the in-gap modes in the Landau band structure. The proof is based on mapping fermions under magnetic fields to a topological insulator whose topological number is exactly the topological charge of the Fermi point. Our work lays a solid foundation for the study of intriguing magneto-response effects of topological fermions.

description: Aim: We investigated cost effectiveness of benralizumab vs. standard of care (SOC) plus oral corticosteroids (OCS) for patients with severe, eosinophilic OCS-dependent asthma in Sweden. Materials and methods: A three-state, cohort-based Markov model of data from three Phase III benralizumab clinical trials (ZONDA [NCT02075255], SIROCCO [NCT01928771], and CALIMA [NCT01914757]) was used to assess the incremental cost-effectiveness ratio of benralizumab vs. SOC plus OCS. Health outcomes were estimated in terms of quality-adjusted life-years (QALYs). The model included costs and disutilities associated with extrapolated OCS-related adverse events. Patients with severe asthma were defined as those receiving OCS ≥5 mg/day. Results: Benralizumab demonstrated a cost-effectiveness ratio vs. SOC plus OCS of 2018 Swedish Kronor (SEK) 366,855 (€34,127) per QALY gained, based on increases of 1.33 QALYs and SEK 488,742 (€45,344) per patient. Benralizumab treatment costs contributed most to incremental costs. The probability of benralizumab’s being cost-effective with willingness-to-pay (WTP) thresholds between SEK 429,972 (€40,000) and SEK 752,452 (€70,000) ranged from 75% to 99%. Limitations: Potential limitations of these analyses include the use of combined data from three different clinical trials, a one-way sensitivity analysis that did not include mortality and transition estimates, and Observational & Pragmatic Research Institute (OPRI) data from the UK as a proxy of the Swedish health care system. Conclusions: The results of these analyses demonstrate that benralizumab has a high probability of being cost-effective compared with SOC plus OCS for a subgroup of patients with severe, eosinophilic asthma receiving regular OCS treatment and may support clinicians, payers and patients in making treatment decisions.
350 micron SHARC-II Imaging of Luminous High-z Radio Galaxies

description: Using the filled bolometer array SHARC-II on the Caltech Submillimeter Observatory (CSO), we have obtained deep (rms ~ 15mJy/beam), high-quality 350 micron maps of five of the most luminous high-z radio galaxies known. In all cases the central radio galaxy is detected at the >3sigma level, and in some cases the high resolution of SHARC-II (FWHM ~ 9") allows us to confirm the spatially extended nature of the dust emission. In PKS1138-262 (z=2.156), 8C1909+722 (z=3.538) and 4C41.17 (z=3.792), additional sources -- first discovered by SCUBA at 850 micron and believed to be dusty, merging systems associated with the central radio galaxy -- are detected at 350 micron. Furthermore, in PKS1138 and 4C41.17 additional SHARC-II sources are seen which were not detected at 850 micron, although the reality of these sources will have to be confirmed by independent submm observations. Thus, our observations seem to support the notion of extended star formation taking place in radio galaxies at high redshifts, and that these systems sit at the centers of overdense regions harbouring a complexity of dusty and vigorously star forming systems. At the redshift of the radio galaxies, the 350 micron observations sample very close to the rest-frame dust peak (typically at ~100 micron), and they therefore contribute a particularly important point to the spectral energy distributions of these sources, which we use this in conjunction with existing (sub)millimeter data to derive FIR luminosities, dust temperatures and spectral emissivities of the central radio galaxies.

description: Medical image analysis using deep neural networks has been actively studied. Deep neural networks are trained by learning data. For accurate training of deep neural networks, the learning data should be sufficient, of good quality, and should have a generalized property. However, in medical images, it is difficult to acquire sufficient patient data because of the difficulty of patient recruitment, the burden of annotation of lesions by experts, and the invasion of patients' privacy. In comparison, the medical images of healthy volunteers can be easily acquired. Using healthy brain images, the proposed method synthesizes multi-contrast magnetic resonance images of brain tumors. Because tumors have complex features, the proposed method simplifies them into concentric circles that are easily controllable. Then it converts the concentric circles into various realistic shapes of tumors through deep neural networks. Because numerous healthy brain images are easily available, our method can synthesize a huge number of the brain tumor images with various concentric circles. We performed qualitative and quantitative analysis to assess the usefulness of augmented data from the proposed method.

title: Aspects of the biology of Trypanorhynch tapeworms and investigations on their use as biological tags
Creators: name: Bates, Rachel Margaret
Publisher: name: The Open University
Year: 1988

description: Four hundred papers published in refereed papers during the years 1935-1985 were researched for information on the biology of trypanorhynchs, and a publishable host-parasite list was compiled for this period as a complement to the only previous monograph (published forty-five years ago) on all known members of the order Trypanorhyncha (Platyhelminthes: Cestoda). The theoretical information gained from this initial exercise was then used in carrying out original research on trypanorhynchs found in over 1,000 elasmobranch and teleost fish. This led to a choice of three research topics for more detailed investigations: (i) taxonomic studies on four little-known species and the application of this information to fisheries biology, (ii) life-cycle studies on Grillotia erinaceus (van Beneden, 1858) and (iii) the use of Grillotia smaris-gore (Wagener, 1854) Dollfus, 1946 as a biological tag for commercially important teleosts. A pre-requisite of this last problem was the need to review critically all information on the use of parasites as population indicators. Thus a further 100 papers published in primary journals were researched. The work concludes with a discussion of the above and also brief comments on the need for further research on tapeworms of the order Trypanorhyncha as an aid to our understanding of other basic contemporary problems in parasitology, relating to host-specificity, ecology and phylogeny.

description: Der Klimawandel verlangt nach einer Reduzierung der Treibhausgase. Für eine Umset-zung im Gebäudesektor ist das thermische Potenzial von Oberflächengewässern hierfür eine Option. Ihre physikalischen Eigenschaften, wie eine hohe spezifische Wärmekapa-zität sind eine Alternative für das Heizen und Kühlen von Gebäuden oder deren Warm-wasseraufbereitung über Anergienetze. Diese bieten, aufgrund ihres Temperaturniveaus nah der Umgebungstemperatur, geringe thermische Verluste. Obwohl Anergienetze oft in Kombination mit Geothermie genutzt werden, sind Oberflächengewässer eine Alterna-tive als Wärmequelle. Diese Arbeit analysiert existierende Anergienetze und leitet Empfehlungen für die Pla-nung und Umsetzung ähnlicher Projekte in Deutschland ab. In diesem Rahmen werden grundlegende Kenntnisse von Verteilungsnetzen und deren Energiefluss, mit Fokus auf Anergienetze, dargestellt. Anschließend werden deren Struktur und Komponenten sowie grundsätzliche Eigenschaften von Oberflächengewässern genannt und Anforderungen und Rahmenbedingungen für deren Nutzung als Wärmequelle in Anergienetzen be-schrieben. Mögliche Systemkonfigurationen werden aufgezählt und in Hinblick auf ihre Eigenschaften verglichen. Der Hauptteil vergleicht vier existierende Anergienetze, um unterschiedliche Umsetzungen bezüglich gegebener gesetzlicher Vorgaben und Ver-ordnungen zu evaluieren. Zwei der diskutierten Netze nutzen als Wärmequelle stehende Gewässer in der Schweiz und zwei fließende Gewässer in Deutschland. Als Ergebnis werden existierende gesetzliche Vorgaben und Verordnungen der Schweiz aufgezeigt und erforderliche Aspekte für Projekte in Deutschland zusammengefasst, als erster Schritt, um den in Deutschland fehlenden gesetzlichen Vorgaben und Verordnungen entgegen zu wirken.

description: We have conducted a search for new strong gravitational lensing systems in the Dark Energy Spectroscopic Instrument Legacy Imaging Surveys' Data Release 8. We use deep residual neural networks, building on previous work presented in Huang et al. (2020). These surveys together cover approximately one third of the sky visible from the northern hemisphere, reaching a z band AB magnitude of ~22.5. We compile a training sample that consists of known lensing systems as well as non-lenses in the Legacy Surveys and the Dark Energy Survey. After applying our trained neural networks to the survey data, we visually inspect and rank images with probabilities above a threshold. Here we present 1210 new strong lens candidates.

description: Die Bilder und Meldungen der letzten Wochen aus Bolivien, Ecuador und Peru vermitteln den Eindruck, dass politische Instabilität sukzessive von einem auf den anderen zentralen Andenstaat übergreift. Hauptakteure sind wütende Volksmassen und hilflose Regierungen, die sich als Konfliktparteien gegenüberstehen. Während Carlos Mesa im bolivianischen La Paz als Präsident zurücktrat und prophezeite, dass ein Scheitern des Reformprozesses die Unregierbarkeit Boliviens zur Folge hätte, zogen in Ecuador Tausende Demonstranten durch die Straßen Quitos und erzwangen die Amtsenthebung von Staatschef Lucio Gutiérrez. In Lima und Umland sinken derweil die Popularitätswerte des Präsidenten Alejandro Toledo unter zehn Prozent. Dieser Beitrag skizziert wesentliche Merkmale der politischen und zivilgesellschaftlichen Auseinandersetzung in Peru und Bolivien, unter Einbeziehung der aktuellen Entwicklungen in Ecuador.

From the mill to the hill : race, gender, and nation in the making of a French-Canadian community in Maillardville, BC, 1909-1939
Creators: name: Lapointe, Geneveieve
Publisher: name: University of British Columbia
Year: 2011

description: This study looks at the making of a French-Canadian community in Maillardville, British Columbia, between 1909 and 1939. Drawing on oral history transcripts, as well as textual and visual documents, From the Mill to the Hill explores how complicated and contested relations of race, class, gender, and sexuality intertwined to constitute a French-Canadian identity and community in Maillardville prior to the Second World War. Using critical discourse analysis as methodology, this study examines the narratives of 23 men and women who were interviewed in the early 1970s and lived in Maillardville in the period preceding that war. Newspaper articles, city council minutes, company records, church records, as well as historical photographs culled from various archives and a local museum, also serve as primary documents. From the Mill to the Hill argues that a French-Canadian identity and community was constructed in Maillardville between 1909 and 1939 through the racialization of bodies and spaces. Narratives about the myth of the frontier, the opposite "other," and the racialization of the space in and around the company town of Fraser Mills illustrate how identity construction operated within a gendered and racialized framework. Secondly, this study excavates the fragile "whiteness" of French Canadians as both colonizers and colonized in British Columbia. Even though these French Canadians were de facto Canadian citizens - thus entitled to purchase land, and (for the men) vote in elections - they were also working-class, poor, Roman Catholic, and French-speaking - all attributes that made them inferior in the eyes of English-speaking Canadians of Protestant British descent. Finally, this thesis explores the moral regulation of gender roles, heteronormativity, and wedding ceremonies. Looking specifically at the institutional power of the Roman Catholic religion and education, this research shows how the French Canadians' fragile whiteness was also fractured along axes of gender and sexual inequalities.

description: Port-Hamiltonian systems theory provides a structured approach to modelling, optimization and control of multiphysical systems. Yet, its relationship to thermodynamics seems to be unclear. The Hamiltonian is traditionally thought of as energy, although its meaning is exergy. This insight yields benefits: 1. Links to the GENERIC structure are identified, making it relatively easy to borrow ideas from a popular framework for nonequilibrium thermodynamics. 2. The port-Hamiltonian structure combined with a suitable bond-graph syntax is expected to become a main ingredient in thermodynamic optimization methods akin to exergy analysis and beyond. The intuitive nature of exergy and diagrammatic language facilitates interdisciplinary communication that is necessary for implementing sustainable energy systems and processes. Port-Hamiltonian systems are cyclo-passive, meaning that a power-balance equation immediately follows from their definition. For exergetic port-Hamiltonian systems, cyclo-passivity is synonymous with degradation of energy and follows from the first and the second law of thermodynamics being encoded as structural properties.

description: We report photometry and spectroscopy of the novalike variable DW Cancri. The spectra show the usual broad H and He emission lines, with an excitation and continuum slope characteristic of a moderately high accretion rate. A radial-velocity search yields strong detections at two periods, 86.1015(3) min and 38.58377(6) min. We interpret these as respectively the orbital period P_orb of the binary, and the spin period P_spin of a magnetic white dwarf. The light curve also shows the spin period, plus an additional strong signal at 69.9133(10) min, which coincides with the difference frequency 1/P_spin-1/P_orb. These periods are stable over the 1 year baseline of measurement. This triply-periodic structure mimics the behavior of several well-credentialed members of the "DQ Herculis" (intermediate polar) class of cataclysmic variables. DQ Her membership is also suggested by the mysteriously strong sideband signal (at nu_spin-nu_orb), attesting to a strong pulsed flux at X-ray/EUV/UV wavelengths. DW Cnc is a new member of this class, and would be an excellent target for extended observation at these wavelengths.

description: Our present study deals with the synthesis of a heterogeneous catalyst (CuL@Al2O3). Initially [CuL], having the formula [Cu(L)(H2O)](NO3) (HL = 2-[(3,5-dichloro-2-hydroxy-benzylidene)-amino]-2-hydroxymethyl-propane-1,3-diol, obtained from condensation between 3,5-dichloro-2-hydroxybenzaldehyde and 2-amino-2-(hydroxymethyl)propane-1,3-diol), has been synthesized, followed by immobilization of [CuL] on alumina to generate the catalyst. The catalyst has been characterized by SXRD, UV-vis, FT-IR and SEM. Ground-state structure of the homogeneous catalyst [CuL] was optimized by Density Functional Theory (DFT) and Time-Dependent DFT (TD-DFT) calculations. This catalyst exhibits appreciable catalytic activity towards oxidation of alcohols by using hydrogen peroxide as oxidant. Through ESI-MS study, it becomes possible to isolate intermediate species of the catalytic oxidation. Finally, a plausible mechanistic pathway has been proposed to elucidate the role of each substituent of the catalytic system. Prepared (CuL@Al2O3) offers a number of advantages such as easy work-up and separation of the catalyst from the reaction mixture by centrifugation, recyclability for six times with minimal loss of activity along with the high yield of product.

description: With numerous ongoing deployments owned by private companies and startups, dense satellite constellations deployed in low Earth orbit (LEO) will play a major role in the near future of wireless communications. In addition, the 3rd Generation Partnership Project (3GPP) has ongoing efforts to integrate satellites into 5G and beyond-5G networks. Nevertheless, numerous challenges must be overcome to fully exploit the connectivity capabilities of satellite constellations. These challenges are mainly a consequence of the low capabilities of individual small satellites, along with their high orbital speeds and small coverage due to the low altitude of deployment. In particular, inter-plane inter-satellite links (ISLs), which connect satellites from different orbital planes, are greatly dynamic and may be considerably affected by the Doppler shift. In this paper, we present a framework and the corresponding algorithms for the dynamic establishment of the inter-plane ISLs in LEO constellations. Our results show that the proposed algorithms increase the sum of rates in the constellation 1) by up to 115% with respect to the state-of-the-art benchmark schemes in an interference-free environment and 2) by up to 71% when compared to random resource allocation in a worst-case scenario for interference.

description: We investigated the magnetic properties of the ilmenite-type iridate CdIrO$_3$ with a honeycomb lattice formed by Ir$^{4+}$ ions prepared via a solid-state metathesis. The magnetization measurements with using the powder sample reveal a large effective magnetic moment and a fairly strong antiferromagnetic interaction, indicating a deviation from the Kitaev model. Considering the relationship between magnetism and crystal structure in CdIrO$_3$ with comparing with the other ilmenite-type iridates ZnIrO$_3$ and MgIrO$_3$, we conclude that insulating CdIrO$_3$ cannot be describe as a $J_{\rm eff} = 1/2$ Mott state owing to a metathetically-stabilized large trigonal distortion of IrO$_6$ octahedra.

description: Bolivien zeigt sich dieser Tage mal wieder gespalten. Auch wenn die Dezemberwahlen 2005 mit dem ersten indigenen Präsidenten Evo Morales einen eindeutigen Gewinner hervorbrachten, so halten etwa die Diskussionen über die staatliche Energie- und Ressourcenpolitik unvermindert an. Es geht dabei um die bereits vollzogene Verstaatlichung der nationalen Öl- und Erdgasvorkommen, die womöglich bald folgende von Forstwirtschaft und Bergbau sowie eine angekündigte Reform der agrarischen Besitzverhältnisse. Die Mehrheit der indigenen Bevölkerung sieht in diesem Politikwandel die lang ersehnte Realisierung einer gerechteren Aufteilung kollektiven Eigentums. Dagegen erkennen vor allem Mestizen und Weiße in den Verstaatlichungen den problematischen Versuch Morales’, dem Namen seiner Regierungspartei „Movimiento al Socialismo“ zur Verwirklichung verhelfen zu wollen: die „Bewegung hin zum Sozialismus“. Anliegen dieses Beitrages ist es nicht zu klären,welches Szenario den Realitäten in Bolivien näher kommt. Auch stehen nicht die schwer abschätzbaren Auswirkungen der staatlichen Ressourcenpolitik im Fokus. Vielmehr möchte dieser Beitrag die Fragmentierung der bolivianischen Gesellschaft beleuchten und anhand eines regionalen Beispiels verdeutlichen, dass interkulturelles Zusammenleben in Bolivien gelingen kann, wenn es denn ausprobiert wird.

DESCRIPTION
Cylindrical branches, 1.01-1.64 mm in diameter, with 0.44- 0.80 mm wide endozone and 0.30-0.60 mm wide exozones. Autozooecia long, cylindrical, budding parallel to the branch axis for a long distance, gently curved toward to the colony surface. Autozooecial apertures oval. Thin, planar diaphragms rare in autozooecia. Tectitozooecia abundant, separating autozooecia in 1-3 rows, restricted to exozone, covered by thick calcitic skeleton on the colony surface. Acanthostyles large, having distinct hyaline cores, 4-9 surrounding each aperture and arranged irregularly in spaces between autozooecia. Autozooecial walls laminated, having dark serrated boundaries, 0.020 -0.025 mm thick.
COMPARISON
 Clausotrypa ramosa (Owen, 1973) is similar to C. monticula (Eichwald, 1860) but differs from it in smaller distances between aperture centres (averagely 0.76 mm vs 0.81 mm in C. monticola).

Symmetry of the phonon landscape across the duality boundary of twisted kagomes lattices

description: In this work, we investigate the symmetry of the phonon landscape of twisted kagome lattices across their duality boundary. The study is inspired by recent work by Fruchart et al. [Nature, 577, 2020], who specialized the notion of duality to the mechanistic problem of kagome lattices and linked it to the existence of duality transformations between configurations that are symmetrically located across a critical transition point in configuration space. Our first goal is to elucidate how the existence of matching phonon spectra between dual configurations manifest in terms of observable wavefield characteristics. To this end, we explore the possibility to aggregate dual kagome configurations into bi-domain lattices that are geometrically heterogeneous but retain a mechanically homogeneous response. Our second objective is to extend the analysis to structural lattices of beams, which are representative of realistic cellular metamaterials. We show that, in this case, the symmetry of the phonon landscape across the duality boundary is broken, implying that the conditions for dual behavior do not merely depend on the geometry, but also on the dominant mechanisms of the cell, suggesting a dichotomy between geometric and functional duality.

description: Dry season conditions are a major constraint to ruminant production in the Caribbean region, limiting both pasture quantity and quality. Preservation of forage as silage under favorable growing conditions is one means of stockpiling forage for dry season use. This pilot study compared growth and intake by hair sheep lambs fed sorghum silage with those fed native pasture green chop (predominantly Panicum maximum and Leucaena leucocephala). The silage samples were pooled from a sorghum variety/alley cropping trial, which were ensiled either with (3%) or without the addition of molasses. Fifteen wether lambs were assigned to the 3 treatment groups (n=5) and group-fed daily a diet of either green chop (GC), silage (S) or silage with molasses (S+H) and coconut meal (CH) at 5 and 2% of body weight on an as fed basis for 24 d following a 4-d adjustment period on a composite diet. Refusal of feedstuffs was recorded daily. Average daily gain was 110, 52 and 84 g/d for GC, S and S+H diets, respectively, and differences approached significance (P~0.15). Roughage dry matter intake was similar between treatment groups (263 to 287 g/d), but supplement intake varied from 232 g/d (S) to 364 g/d (GC). Total dry matter intake was 651, 495 and 550 g/d for CC, S and S+H, respectively. Despite the increased CH intake by GC, the gain/feed ratio was higher (0.169) compared Ito S (0.105) and S+H (0.152). Plasma urea nitrogen (PUN) increased by 9.3, 5,9 and 6.6 mg/dl from d 1 to d29 of the study for animals on GC, S and S-t·H diets, respectively. These preliminary data indicate that lambs receiving sorghum ensiled with molasses, but not plain sorghum silage, approached the growth rate of lambs receiving green chopped pasture.
Induced vs Spontaneous Breakdown of S-matrix Unitarity: Probability of No Return in Quantum Chaotic and Disordered Systems

description: We investigate systematically sample-to sample fluctuations of the probability $τ$ of no return into a given entrance channel for wave scattering from disordered systems. For zero-dimensional ("quantum chaotic") and quasi one-dimensional systems with broken time-reversal invariance we derive explicit formulas for the distribution of $τ$, and investigate particular cases. Finally, relating $τ$ to violation of S-matrix unitarity induced by internal dissipation, we use the same quantity to identify the Anderson delocalisation transition as the phenomenon of spontaneous breakdown of S-matrix unitarity.
