Abstract:
Abstract This article investigates Beethoven’s connection to the Bavarian Catholic theologian Johann Michael Sailer (1751–1832), the importance of which has been understated or misunderstood in the existing Beethoven literature. Drawing on historical studies of the complex relationship between Catholicism and the German Enlightenment, it provides a detailed and nuanced account of Sailer’s theology, situating it within the fierce debates that took place among German Catholics in this period. The article goes on to examine the contents of three books by Sailer in Beethoven’s possession, and to show how key ideas in these books resonate with features of Beethoven’s Missa solemnis, which he worked on around the time he was exposed to Sailer’s ideas. In conclusion, the article argues that a deeper understanding of Sailer and his possible influence on Beethoven should prompt a reconsideration of long-standing assumptions regarding the composer’s religious outlook, which may have been more sympathetic to Catholicism than has previously been supposed.

Abstract:
Since the phylogenetic analysis of the Herrichella clade (Ochlerini) new genera were described to fit monophyletic groups inferred and considered to be new taxa. The clade I supported by two synapomorphies of the female genitalia, grouped Alitocoris brunneus Sailer together to two new species. Alloeogyna gen. nov. is described here for this clade including the two new species Alloeogyna ampla sp. nov. and Alloeogyna poecila sp. nov. and a new combination is proposed for Alloeogyna brunnea comb. nov.. Also, Alitocoris maculosus Sailer recovered within the clade E in the Herrichella clade is here redescribed in the monotypic Sailerus gen. nov. resulting in the new combination Sailerus maculosus comb. nov..

Abstract:
Abstract Motivation Single-cell sequencing assay for transposase-accessible chromatin (scATAC-seq) provides new opportunities to dissect epigenomic heterogeneity and elucidate transcriptional regulatory mechanisms. However, computational modeling of scATAC-seq data is challenging due to its high dimension, extreme sparsity, complex dependencies and high sensitivity to confounding factors from various sources. Results Here, we propose a new deep generative model framework, named SAILER, for analyzing scATAC-seq data. SAILER aims to learn a low-dimensional nonlinear latent representation of each cell that defines its intrinsic chromatin state, invariant to extrinsic confounding factors like read depth and batch effects. SAILER adopts the conventional encoder-decoder framework to learn the latent representation but imposes additional constraints to ensure the independence of the learned representations from the confounding factors. Experimental results on both simulated and real scATAC-seq datasets demonstrate that SAILER learns better and biologically more meaningful representations of cells than other methods. Its noise-free cell embeddings bring in significant benefits in downstream analyses: clustering and imputation based on SAILER result in 6.9% and 18.5% improvements over existing methods, respectively. Moreover, because no matrix factorization is involved, SAILER can easily scale to process millions of cells. We implemented SAILER into a software package, freely available to all for large-scale scATAC-seq data analysis. Availability and implementation The software is publicly available at https://github.com/uci-cbcl/SAILER. Supplementary information Supplementary data are available at Bioinformatics online.

Abstract:
Alitocoris Sailer, 1950 possui quatro espécies válidas, descritas da América Central, sendo A. schraderi Sailer, 1950 a espécie tipo. O gênero foi reconhecido como parafilético na filogenia de Ochlerini, e o encontro de espécies não descritas das Américas Central e do Sul, supostamente pertencentes a Alitocoris, torna necessária a identificação e caracterização dos grupos monofiléticos. Para tanto foi feita, no software TNT, uma análise cladística de 40 táxons e 88 caracteres morfológicos, incluindo as espécies de Alitocoris e 16 espécies novas. Utilizou-se comparação com grupo externo, buscas heurísticas com o algoritmo TBR, retenção de 100 árvores e 1000 aleatorizações, cálculo de consenso estrito, índice de consistência (CI), de retenção (RI) e suporte de Bremer. O enraizamento dos cladogramas foi feito no grupo externo, Adoxoplatys Breddin, 1903. A análise resultou em 48 cladogramas de 264 passos, CI=39 e RI=64; e consenso com 285 passos, CI=36 e RI=59. Confirmou-se o parafiletismo de Alitocoris, com suas espécies distribuídas em quatro clados distintos. Alitocoris brunneus Sailer, 1950 formou uma politomia com sp. n. 15 e sp. n. 17, clado suportado por uma sinapomorfia exclusiva (Bremer=1) e irmão de sp. n. 5+sp. n. 10, este suportado por sete sinapomorfias sendo uma exclusiva (Bremer=2). Alitocoris schraderi é grupo irmão de sp. n. 11 com suporte de três sinapomorfias homoplásticas (Bremer=1) e A. maculosus Sailer, 1950 irmão de sp. 09, suportado por uma sinapomorfia exclusiva e uma homplástica (Bremer=1), ambos os grupos posicionados em uma politomia. Alitocoris parvus (Distant, 1880) agrupou com as demais nove espécies novas no clado apical sp. n. 07+, com suporte de três sinapomorfias homoplásticas (Bremer=1). Os resultados implicam em modificações na classificação de Alitocoris, que passa a ser composto por A. schraderi e seu grupo irmão sp. n. 11, além de A. maculosus e das espécies novas 6 e 9 que serão mantidas no gênero até que seja possível o esclarescimento de suas relações, com o acrécimo de mais espécimes. As espécies A. brunneus e A. parvus são transferidas a novos gêneros, propostos para os clados a que pertencem, respectivamente A. brunneus* e sp. 07+. O clado sp. n. 5+sp. n. 10 também comporá um novo gênero. Os novos táxons são propostos com base nas sinapomorfias que suportam cada ramo.

Abstract:
Universitaire, puis évêque à l'action et aux relations multiformes, Johann Michael Sailer (1751-1832) fut, en un temps de profonde transition, une haute figure du catholicisme bavarois. De son ample oeuvre se dégage une doctrine spirituelle féconde, écho de sa riche expérience individuelle, communautaire, interconfessionnelle. Certes, Sailer connut l'ombre du discrédit. Car sa manière d'être, son christianisme qui séduisait par son ouverture et son dynamisme, intriguaient. Sa personnalité cependant et son enseignement, forgé de l'Aufklärung au romantisme, au rythme de ses "noviciats", lectures, relations, ont fait de lui un maître spirituel pour son temps. Cette thèse se propose d'éclairer, selon une approche interdisciplinaire, la cohérence interne entre la vie et l'oeuvre de Sailer, la genèse et la maturation de sa pensée, la place unique prise par Sailer dans l'histoire des idées. C'est toute la spécificité de la religion sailérienne que d'être revenue aux sources du christianisme pour y puiser des principes vivants, dans un perpétuel dialogue avec l'esprit du temps et une inlassable confrontation avec sa philosophie. La théologie de Sailer a pour fondement l'histoire divino-humaine du salut. Son christianisme déploie sa réalité sotériologique dans les profondeurs de l'être, comme dans la communauté humaine et les divers domaines de la vie. L'esprit sailérien, transmis par toute une école de pensée, a par là marqué de son empreinte l'histoire religieuse, mais aussi la vie politique, universitaire, culturelle du temps et connu une renaissance, signe de son indéfectible fécondité et actualité
Johann Michael Sailer (1751-1832), academic and bishop, was a leading figure of Bavarian Catholicism, whose multifarious action and personal relationships greatly influenced an age in which significant changes were taking place. A rich spiritual doctrine echoing his individual, interdenominational, and congregational experience may be derived from his extensive work. Admittedly, Sailer fell into disrepute. For other people found his way of life and his Christian faith, characterized by their open-mindedness and dynamism, both appealing and intriguing. However, his personality and his lectures, based on views ranging from the Enlightenment to the romantic movement, through his "noviciates", reading, and personal relationships, turned him into a spiritual guide for the age that he lived in. This dissertation intends to shed light, from an interdisciplinary approach, on the internal consistency of Sailer's life and works, the origin of his thought, how his ideas matured, and his unique place in the history of ideas. The specificity of Sailer's religion consisted in drawing principles that were still very much alive from the sources of primitive Christianity, while constantly engaging in a dialogue with the spirit of the time and confronting its philosophy. Sailer's theology is based on the divine and human history of salvation. His Christianity develops its soteriology in the depths of the human psyche, as well as human community and every field of life. Sailer's spirit thus influenced the religious history as well the political, cultural and academic life of his time, but has also been handed down by a school of thought and now revived, which only schows that it is indestructibly fruitful and still relevant today

Based on nearly sixty years experience with nine different racing and cruising boats, Dick Miller decided that one of those hulls could be converted to an ideal "old man's" day sailer. The basis for his design, changes made in rig and hull, and the resulting MAGIC III are described in this paper.

Full text
Abstract:
In small sailboats, the bodyweight of the sailor is proportionately large enough to induce significant unsteady dynamics of the boat and sail. Sailors use a variety of techniques to create sail dynamics which can provide an increment in thrust, increasing the boatspeed. In this study, we experimentally investigate the unsteady aerodynamics associated with two such techniques, “upwind leech flicking" and “downwind S-turns". We employ a two-part approach. First, on-the-water experiments are carried out using a Laser class sailboat sailed by Olympic and world championship level sailors. Data collected from an on-board GPS, IMU, anemometer, and camera array is used to generate characteristic motions of the boat and sail relative to the apparent wind. Second, laboratory experiments using the characteristic motion of the sail are run in a computer-controlled 3 degree-of-freedom (X, Y, and θ) towing tank. We use water as the working fluid. Rather than directly experiment with three-dimensional sail shapes, we represent the primary effects of the sail dynamics using rapidly prototyped two-dimensional flexible sail geometries. Shapes are based on extruded draft stripes from the upper third of the sail. The laboratory experiments approximately match the key non-dimensional parameters of the on-the-water sailing conditions, including the reduced frequency and heave-to-chord ratio. Particle Image Velocimetry and force measurements are used to analyze the flow field and thrust generated by the model sail during the dynamic motions. On-the-water testing shows that the characteristic sail motion in leech flicking is a combination of periodic heave caused by the actions of the sailor and a passive twisting of the sail due to rig flexibility. The heaving sail motions are due to rotation (roll) of the rig around the longitudinal axis of the hull. This is at an angle to the apparent wind, resulting in heave that has components both perpendicular and parallel to the oncoming wind flow. This is distinct from classical aerodynamic studies with heave purely perpendicular to the incoming flow. In laboratory experiments, the characteristic flicking motion is applied to a NACA 0012 airfoil and a 2D sail, both angled at 15 deg to the flow. Lift increases and drag decreases, leading to an overall increase in resultant driving force of the boat. The beneficial effect of this dynamic motion becomes greater as the apparent wind angle increases. In the case of leech flicking, the experiments show that the formation of vortex pairs is fundamental to the augmented thrust due to heaving. The presence of S-turns, whereby the sailor changes the boats direction simultaneous with rolling the boat, generally in the downwind direction, is also associated with vortex formation and pairing, which will be described at the conference. During downwind S-turns, large amplitude heaving motions are paired with substantial rotations of the sail caused by both adjustments of the main sheet and changes in heading. Increased velocity made good downwind is measured from the on-the-water experiments, and is associated with an increase of thrust during characteristic dynamics of the airfoil or sail shape in the laboratory.

Abstract:
Linear dynamic models are extremely useful in autonomous vehicle controller development because they are straightforward to estimate from real data and they enable advanced control system design. To date an in depth investigation of the possibility of using a linear dynamic system model to represent sailing yacht dynamics has not been made. A non-linear simulation of a 10m racer/cruiser racer and full-scale data collected aboard a 23 ft day-sailer are used in conjunction with the one-shot least squares estimation algorithm to evaluate this possibility. Using the non-linear simulation data it is found that it is possible to use a linear model to represent sailing yacht. Full-scale data collected while sailing upwind on a port tack is used to estimate 10 different linear models.

Abstract:
When a sailboat is sailing in the general direction of the wind, it is known as downwind sailing. Under these conditions boats generally carry two sails — a mainsail and a spinnaker. The flow over these sails is complicated and poorly understood. An issue of importance to sailors is how the adjustment of one sail affects the aerodynamics of the other sail and the total driving force. In the present work a CFD analysis was performed on two different sailboat rigs, with an emphasis on the interactions between the main and spinnaker. The results show that the optimum angle of attack of the mainsail is generally 60° to 70°, depending on the direction of the wind relative to the boat. The correct setting for a mainsail has been a point of debate amongst sailors, and the present analysis supports the theory of easing the mainsail until it luffs (or flaps), then pulling it in. A surprising result is that when the wind is directly behind the boat, the mainsail should not be set to maximize projected area, but eased out past 90°. This is difficult to accomplish in practice due to restrictions of the rig, but raise some interesting questions.

Abstract:
A method is described to conduct an integrated Fluid-Structure Interaction (FSI) simulation of sails that is based upon knowledge of the sail’s design shape geometry and membrane material properties. A Finite Element Analysis (FEA) of the sail structure and a Computational Fluid Dynamics (CFD) model of the aerodynamic field are combined and iteratively solved to compute the actual flying shape of the sail under aerodynamic load, the stress strain behavior of the sail membrane, the integrated aerodynamic forces produced by the sail such as driving force and heel moment, and the resulting loads on sheets, halyards, etc. An important contribution of this particular method is the incorporation of wrinkling phenomena into the FEA portion of the calculation. Results from a study of working sails for a 30’ MORC racing yacht designed by Nelson-Marek (NM) in the 1990’s are presented and discussed with particular emphasis on the variability of primary load paths with changing trim and sailing conditions as well as the impact of sail deformation in the direction of relatively small stresses that is often poorly addressed in many proprietary sail construction methods.

Abstract:
Although competitive sailing yachts may sail fast today this is mainly due to material progress, not sail design. It is always difficult to design a set of sails for a given boat and sailing conditions. A sail has one design shape but an infinite number of corresponding flying shapes depending on materials, trimming, rigging and wind conditions. In this paper a computational framework for sail analysis, design and optimization has been extended to Fluid-Structure Interaction (FSI) and will be presented. The multi-physics computational framework is based on a viscous Computational Fluid Dynamics (CFD) solver for the fluid part and on a nonlinear structural modelling for the structural part. A loose coupling of both models has been implemented to be able to make Fluid-Structure Interaction simulations on various sail configurations and to investigate the relation between a design shape and its corresponding flying shapes. The computational framework presented also contains an optimization package based on derivative free evolutionary strategies to address complex, nonlinear optimization problems. It will be used on few examples of sail design questions to illustrate how it may contribute to put some rational elements in a rather frequently passionate discussion between sailors, sail designers, naval architects and amateurs to design the right set of sails for a given boat.

Abstract:
The velocity prediction program, VPP, appeared on the yachting scene about ten years ago and it now dominates design and sailing. Originally implemented as a handicapping tool under the Measurement Handicap System, now accepted internationally as IMS, it has seen widespread acceptance for many other uses, from design to tuning and racing. This capability means that it is productive, even necessary, for the typical sailor interested in good performance to understand how to apply a VPP to his activities. To do so requires an appreciation of how a VPP functions and how it is applied to practical sailing problems, such as sail selection or tactics. The paper presents a review of VPP fundamentals and then treats the following applications: - Sail selection and strategy for offshore yachts. - Tuning and optimization of all boats. It is the goal of the paper to impart a working understand­ing of the VPP to many sailors so that they can take advantage of the technology in their normal activities.

Abstract:
There are many factors critical to the success of a Whitbread Round The World Race™ campaign. One of the most significant is the design, construction, and selection of an individual leg inventory of offwind sails. As a result of the technical challenges to the experimental and computational analysis of offwind sails, shape development for this class of sails has historically relied upon empirical efforts. An added element for any advanced, state-of-the-art, sail development program is the extensive reliance upon wind tunnel results to guide sail shape improvement and leg inventory selection of offwind sails. Lessons regarding improved offwind sail shapes, construction techniques, use of exotic materials, and sail trim learned or reinforced during the 1997-98 Whitbread Round the World Race sail development program for Swedish Match, are described with particular emphasis placed on the role of wind tunnel testing.

Abstract:
Some years ago, in 1975, I presented a paper and a slide show at an earlier sailing yacht symposium in Annapolis. The subject was a four-year, 28,000 mile cruise I had made in the years 1965 - 1968 most of the way around the world: Hawaii and the South Pacific, New Zealand, Australia's Barrier Reef, the Indian Ocean, the Red Sea, the Mediterranean, including the Greek Islands, an Atlantic crossing to Barbados from the Canary Islands, the Caribbean, and home to the Chesapeake. The paper I wrote then was entitled "Extended Cruising: An Overview" and contained sketches and data from my logs. It was same 55 pages long and talked about many facets of cruising from my vantage point, primarily as seen from the decks of Mamari, the 28 foot ketch I had bought in New Zealand. Lest Mamari 's size appear too small, which perhaps would make me seen heroic, recognize that in displacement and accomodations Mamari was the equivalent of a 33 foot boat. To dispel one other misconception, be advised that I normally sailed with a crew of two, sometimes more, and only sailed two legs single-handed, of about 500 miles each, one from Tonga to Fiji in the Pacific, the other in the Gulf of Suez and from Port Said to the Greek Islands. The 1975 paper reflected my background as a naval architect, combined with my experience as a sailor. I told of things I learned from others. I analyzed log data, presented photographs, drawings and tables, and wrote a series of "yarns" such as sailors spin about their travels. The paper is touched with a flavor of the sea, a flavor of talk over run or coffee in a snug anchorage or on a shared night watch. That 1975 paper makes good reading, and much of the information is still valid. It could be reprinted and if there is enough interest l will do so (contact me). This present paper is a brief look at my experiences on a series of sailing trips, but in particular a one year voyage in a 37 foot yawl from Turkey to the Chesapeake via the West Indies in 1980-81. The paper answers the question posed at the 1975 symposium, would I do the trip again? Then, I thought so, but could not be sure, now my reply is, "of course."
