<p>Hand-made stippling has been used frequently in the process of drawing illustrations for documenting archaeological pieces. This is due to the fact that this technique represents in an efficient way shapes, tones, and textures, by means of distributing dots on the paper. The process of stippling has needed traditionally the ability of an artist, who usually produces the illustration from photographs. In this paper, a program that generates stippling illustrations of high quality is presented. The developed interface makes possible that any user can generate illustrations without the need of artistic abilities. The program is able to work in realtime, allowing the user interacts with the program. We have developed several artistic techniques in high level tasks that allow to improve the final results.</p>

Chengde City boasts a wealth of high-quality mineral water resources characterized by a high level of strontium (Sr), a low level of sodium, and low alkalinity. In order to study the mechanism of formation of Sr-bearing mineral water in Chengde and to scientifically guide future mineral water exploration, taking three typical mineral water exploration areas in Chengde as examples, this paper studies the sources of Sr in mineral water and the general rules of its dissolution via a laboratory static leaching experiment and impact experiments, and it provides an analysis of the characteristics of typical rock samples. The research results indicate that the content of Sr in surrounding rock and the characteristics of minerals existing in surrounding rock jointly control the dissolution of Sr in water; that CO2 can promote the formation of mineral water containing Sr; and that temperature increases may boost the dissolution of Sr from carbonate minerals but also inhibit the dissolution of Sr from silicate minerals.

Abstract Specialized studies show how a fighter should physically be, not just any fighter, but the one who possesses the qualities and features of the ideal model, i.e. those elements that define the near-perfect fighter. The demands of the modern battlefield impose a high quality human potential that provides a good basis for the selection and training of fighters. Resistance to physical, climate, season and weather condition demands, to the prolonged efforts fighting requires is one of the important conditions of success. The paper presents information with particular impact in optimizing exercise capacity for future officers of the land forces, emphasizing once again the idea that a high level of motric ability is an essential objective.

AbstractCiliates are microbial eukaryotes with distinct somatic and germline genomes. Post-zygotic development involves extensive remodeling of the germline genome to form somatic chromosomes. Ciliates therefore offer a valuable model for studying the architecture and evolution of programmed genome rearrangements. Current studies usually focus on a few model species, where rearrangement features are annotated by aligning reference germline and somatic genomes. While many high-quality somatic genomes have been assembled, a high quality germline genome assembly is difficult to obtain due to its smaller DNA content and abundance of repetitive sequences. To overcome these hurdles, we propose a new pipeline SIGAR (Splitread Inference of Genome Architecture and Rearrangements) to infer germline genome architecture and rearrangement features without a germline genome assembly, requiring only short germline DNA sequencing reads. As a proof of principle, 93% of rearrangement junctions identified by SIGAR in the ciliate Oxytricha trifallax were validated by the existing germline assembly. We then applied SIGAR to six diverse ciliate species without germline genome assemblies, including Ichthyophthirius multifilii, a fish pathogen. Despite the high level of somatic DNA contamination in each sample, SIGAR successfully inferred rearrangement junctions, short eliminated sequences and potential scrambled genes in each species. This pipeline enables pilot surveys or exploration of DNA rearrangements in species with limited DNA material access, thereby providing new insights into the evolution of chromosome rearrangements.

This paper examines the involvement of sixteen undergraduate students across four disciplines in a practice-led research project to create the “Once Upon a Time in Palestine” XR documentary by exploring how they performed when given complex challenges, to create this novel and complex practice-led research project. The students were trained and mentored but also were trusted to work under minimal supervision. This created a high level of engagement with the expectation of high-quality output and presented the students with opportunities not afforded to them within the rigid structure of their academic programs. This paper examines the engagement of the students, and their willingness to learn new technologies and apply this learning to produce high quality output under tight deadlines with minimal supervision and the value of interdisciplinary collaboration across multiple fields of study. The paper concludes that while there was a steep learning curve, the students were able to achieve high-level engagement and produce professional results within the specified deadlines, using the latest technological advances in the field, while learning new skills outside their academic program and also enhancing the outcome of the successful project.

Abstract BackgroundManagement of primary aldosteronism (PA) has become a research hotspot in the field of endocrinology. To obtain reliable research evidence, it is necessary to establish a high-quality PA research database. MethodsThe establishment of PA research database involved two steps. Firstly, patients with confirmation of PA diagnosis between 1 Jan 2009 to 31 Aug 2019 at West China Hospital were identified and data were extracted. Secondly, patients with confirmatory testing for PA will be enrolled into a prospective cohort. Data will be prospectively collected based on the case report forms since 1 Sep 2019. We evaluated the quality of research database through assessment of quality of key variables.ResultsTotally, 862 patients diagnosed as PA were identified, of which 507 patients who had positive confirmatory testing for PA were included into the retrospective database. Among 862 patients diagnosed as PA, the mean systolic blood pressure (SBP) was 156.1 mmHg, mean diastolic blood pressure (DBP) was 97.2 mmHg. Among included patients, the mean serum potassium level was 2.85 mmol/L, and the mean plasma aldosterone concentration (PAC) was 28.1 ng/dL. The characteristics patients with positive confirmatory testing for PA were similar. Validation of data extracting and linking showed the accuracy were 100%. Evaluation of missing data showed that the completeness of BMI (95.9%), SBP (99.4%) and DBP (99.4%) were high. ConclusionThrough integrating retrospective and prospective cohort of PA, a research database of PA with high quality and comprehensive data can be established. We anticipate that the research database will provide a high level of feasibility for management of PA in China.

Software architecture is a very important software artifact, as it describes a system’s high-level structure and provides the basis for its development. Software architecture development is not a trivial task; to this end, a number of methods have been proposed to try to systematize their related processes to ensure predictability, repeatability, and high quality. In this chapter, the authors review some of these methods, discuss some specific problems that they believe complicate their adoption, and present one practical experience where the problems are addressed successfully.

In a principal-agent framework under moral hazard, when the monopolist can pass on the liability of any defect of the product to the subcontractors, and cannot credibly commit to a high level of investment, he actually chooses a low investment level and supplies a low quality product if the product replacement cost is below a critical level. However, under contract renegotiation, when the monopolist is taking the entire risk of replacing the defective product, he will profitably choose high investment level and serves high quality product. But the results show that the monopolist will choose to renegotiate the contract only for limited values of product replacement cost, even if renegotiation is socially optimal.

The article deals with projecting that is an important component of the formation of a new pedagogical ideology - lifelong learning. Projecting as an educational function of the pedagogical system, becomes an important factor in human success, generating new ideas and continuous updating of outdated knowledge. It is analyzed that the practice of projecting is so widespread that in a relatively short period of time within the pedagogical system project types of work at different levels of government are actively implemented. In particular, teachers project educational programs, pedagogical technologies, including educational, upbringing, development subsystems. Thus, the preparation of teachers for design activities becomes relevant, and this in turn determines the understanding of the productive application of projecting logic, the formation of technologies for such activities. Project activity is multifaceted and multifunctional, as it allows to form both engineering skills and abilities, as well as psychological and pedagogical. The psychological basis of didactic projecting is the readiness of the individual to constantly improve their competence, mobility of professional functions. In fact, it is a question of training at the university of an engineer-teacher-professional, competent in the main spheres of pedagogical activity. Training of vocational training establishment students, that is aimed at developing the projecting activity related knowledge, skills, and abilities among prospective engineer-educators is supposed to essentially scale up the vocational training quality with high education establishment graduates, to foster development of their professional mobility and competitiveness in the labor market. Hence it is necessary to ensure high level of professional competence among the graduates, which, in turn, is supposed to provide for involvement of each student into high-quality educational and learning; to provide for building up the core research activity features with prospecting professionals, for building up the skills to gain individually up-front knowledge and put it efficiently into practice. The so called educational projecting, being an option for the implementation of high-quality education concept, fully complies with the said requirements.
