Elicitation on Artemisinin Biosynthesis in Artemisia annua Hairy Roots by the Oligosaccharide Extract from the Endophytic Colletotrichum sp. B501

The oligosaccharide elicitor from the mycelial wall of an endophytic Colletotrichum sp. B501 promoted the production of artemisinin in Artemisia annua L. hairy root culture. When hairy roots of 22-day-old cultures (later growth phase) were exposed to the elicitor (20 mg/L) for 4 d, the maximum content of artemisinin reached 1.15 mg/g, a 64.29% increment over the control. The electron X-ray microanalysis disclosed the rapid accumulation of Ca 2+ in the elicited cortical cells of hairy root. The electronic microscope observation revealed the high electron density area in vacuole of elicited cells. During the first day of elicitation the peroxidase activity of hairy roots was improved sharply. Some cellular morphological changes including cell shrinkage, condensation of cytoplasm and nuclear fragmentation, coincident with the appearance of DNA ladders, were observed after the third day of elicitation. It was suggested that the oligosaccharide elicitor triggered the programmed cell death, which may provide the substance or chemical signal for artemisinin biosynthesis.

Economical Requirements Elicitation Techniques During COVID-19: A Systematic Literature Review

Requirements elicitation is a fundamental phase of software development in which an analyst discovers the needs of different stakeholders and transforms them into requirements.This phase is cost-and time-intensive,and a project may fail if there are excessive costs and schedule overruns.COVID-19 has affected the software industry by reducing interactions between developers and customers.Such a lack of interaction is a key reason for the failure of software projects.Projects can also fail when customers do not know precisely what they want.Furthermore,selecting the unsuitable elicitation technique can also cause project failure.The present study,therefore,aimed to identify which requirements elicitation technique is the most cost-effective for large-scale projects when time to market is a critical issue or when the customer is not available.To that end,we conducted a systematic literature review on requirements elicitation techniques.Most primary studies identified introspection as the best technique,followed by survey and brainstorming.This finding suggests that introspection should be the first choice of elicitation technique,especially when the customer is not available or the project has strict time and cost constraints.Moreover,introspection should also be used as the starting point in the elicitation process of a large-scale project,and all known requirements should be elicited using this technique.

Therefore, multi-repeating elicitation with E2, 3, 4 coupled with Biofertilizers F2, 4 could be considered as eco-friendly innovative reliable practical application for sustainable improvement and sustainable use that exceeded significantly over traditional agriculture NPK alone or 1/2 NPK-PGPB for R. officinals.

An Investigation of Confucian Heuristic Teaching Elicitation Teaching Theory Theory and Socrates

Confucianism （especially its teaching theory） is the core of Chinese traditional culture with Confucius as its representative. It has played an indispensable role in the development of Chinese culture. It is the spiritual pillar of Chinese sustainable development. There are no others that can compare with its teaching method and art. The famous ＂heuristic teaching theory＂ is one of its greatest inventions. But many people think that it is Socrates invention. In fact, Socrates ＂elicitation teaching theory＂ was invented far later than that of Confucius. This paper aims at investigating of these two theories.

Probability Elicitation in Influence Diagram Modeling by Using Interval Probability

In decision modeling with influence diagrams, the most challenging task is probability elicitation from domain experts. It is usually very difficult for experts to directly assign precise probabilities to chance nodes. In this paper, we propose an approach to elicit probability effectively by using the concept of interval probability (IP). During the elicitation process, a group of experts assign intervals to probabilities instead of assigning exact values. Then the intervals are combined and converted into the point valued probabilities. The detailed steps of the elicitation process are given and illustrated by constructing the influence diagram for employee recruitment decision for a China’s IT Company. The proposed approach provides a convenient and comfortable way for experts to assess probabilities. It is useful in influence diagrams modeling as well as in other subjective probability elicitation situations.

Local Shear Stresses Elicit Different Mechanical Response and Gene Expression from Complex Stresses

It is well established that living cells and tissues respond to mechanical forces such as flow-related shear stresses in blood or interstitial space and complex tractional stresses at cell-matrix contacts and cell-cell contacts.However,how different modes of forces impact mechanical and biological responses is elusive.Here we describe a strategy of using the three-dimensional magnetic twisting cytometry(3D MTC)technology to apply forces in any desired directions to the same living cell.We reveal that for a fixed stress amplitude and frequency,a live cell exhibits mechanical anisotropy and responds to a local shear stress differently from responding to a local complex stress by stretching chromatin and upregulating gene transcription to different levels,extending our previous finding on force-induced direct gene activation.This finding highlights the importance of force modes in impacting cellular mechanical and biological responses in living cells and tissues and may have implications in tissue patterning and embryonic development.

Eliciting Requirements from Stakeholders’ Responses Using Natural Language Processing

Most software systems have different stakeholders with a variety of concerns.The process of collecting requirements from a large number of stakeholders is vital but challenging.We propose an efficient,automatic approach to collecting requirements from different stakeholders’responses to a specific question.We use natural language processing techniques to get the stakeholder response that represents most other stakeholders’responses.This study improves existing practices in three ways:Firstly,it reduces the human effort needed to collect the requirements;secondly,it reduces the time required to carry out this task with a large number of stakeholders;thirdly,it underlines the importance of using of data mining techniques in various software engineering steps.Our approach uses tokenization,stop word removal,and word lemmatization to create a list of frequently accruing words.It then creates a similarity matrix to calculate the score value for each response and selects the answer with the highest score.Our experiments show that using this approach significantly reduces the time and effort needed to collect requirements and does so with a sufficient degree of accuracy.

Hermeneutical Elicitation of Requirements: A Technical Perspective to Improve the Conception of the Software Requirements

In order to develop quality software that meets the originals needs of its users, it is necessary to perform the Requirements Engineering, so that the software context to be developed is identified, examined and specified properly. However, there is a problem that is increasingly in debate: the difficulty in understanding and establishing the purpose of the software to be developed, as pointed out by important researches in the area, such as the Chaos Report, which indicates that only 29% of software projects are successful, and the Software Engineering Institute, which points out software requirements as a critical factor for the success of software engineering and that deficiencies in this dimension are the main causes of software project failures. This article presents a proposal to address this problem through the use of the Hermeneutical Elicitation of Requirements, which is the conceptual adequacy of some hermeneutical methods in a technical approach that assists the requirements engineer to conceive better of the software requirements. In this way, the software engineer will be better able to develop the software to better meet the needs of its end users and sponsors.

Exogenous Pre-Harvest Treatment with Methyl Jasmonate and Chitosan Elicits Lycopene Biosynthesis in Tomato Plants

In this study, exogenous pre-harvest treatment of tomato plants with MeJA （Methyl Jasmonate） and chitosan was used to elicit lycopene biosynthesis and stimulate plant growth. Lycopene is a bright red carotene and carotenoid pigment found in tomatoes, carrots and other red fruits and vegetables. It is a powerful antioxidant that protects cells from damage and blocks cancerous cell growth. Many studies suggest eating lycopene-rich foods may be directly linked to reducing risk of several cancers, heart disease and stroke, hence there is a need to enhance its levels in tomatoes. Tomato seeds were soaked in MeJA and chitosan solutions of varying concentrations and then planted. The resulting plants were irrigated with the solutions used to soak the seeds, accordingly. The heights of the plants were recorded on a tri-weekly basis and HPLC （High Performance Liquid Chromatography） was used to analyze the effects of the MeJA and chitosan solutions on lycopene yields in the tomato fruits. Analysis of chromatograms obtained from tomato samples in the MeJA and chitosan-treated groups showed enhanced levels of lycopene. Plant growth was not significantly affected by treatment ofMeJA. Chitosan, however, noticeably increased plant growth over 7 weeks.

Discovery of New Stilbene Antioxidants of the Bio-Elicited Peanut Sprout Powder (BPSP) and Longevity Extension of Mice Fed with BPSP-Supplemented Diets

Biosynthesis of peanut stilbenes, including resveratrol as the secondary metabolites, could be enhanced by subjecting the kernels to germination and wound-stress. Investigations of the bio-elicited peanut sprout powder (BPSP) addressed on characterization of the comprising stilbenes and effectiveness in longevity extension deserves intensive research. In this study, peanut kernels were subjected to germination and wound-stress in preparation of BPSP. The methanol extracts of BPSP were medium pressure liquid chromatographic (MPLC) fractionated and semi-preparative HPLC recovered and followed by instrumental identification and biological activity determinations of the isolated stilbenes. In longevity experiments, 16 female 11-mon-old BALB/c mice and both genders of 12-mon-old ICR mice were daily fed with BPSP supplemented diets at doses of 0, 0.1 and 0.5 g BPSP/kg bw for 750 and 762 days, respectively. Based on chemical characterization, enriched quantity of stilbenes in the BPSP up to ca. 1% (w/w) was detected. Two new stilbene compounds, namely, 4, 5’-dihydroxy-6’’-hydroxymethyl, 6’’-methylpyrano [2’’, 3’’: 3’, 4’] stilbene and 3, 4, 5’-trihydroxy-6’’, 6’’-dimethylpyrano [2’’, 3’’: 3’, 4’]stilbene along with 5 known stilbenes were isolated. The 7 stilbenes exhibited potent antioxidative and antiglycative activities and varied with structure-activity nature. Based on the resultant survival curves and average lifespans of both mouse models, basal diets supplemented with BPSP are effective to extend mouse longevity by a dose dependent manner. It is of merit to demonstrate that peanut kernels as a potent producer could be bio-elicited to biosynthesize a broad spectrum of bioactive stilbenes to prepare BPSP which is effective to extend mouse longevity as science-evidenced by the two long-term animal experiments.

Creating Space for Children’s Voices: Utility of the Collage Life Story Elicitation Technique

A challenge for many School-Based Family Counseling(SBFC)practitioners,child psychotherapists and researchers are finding ways to give voice to children and eliciting trustworthy and detailed narratives that could serve as resource for understanding the needs of young clients in the context of all their interpersonal networks.Children are often reticent when asked to self-disclose and tell their stories during consultation.The purpose of the present study was to examine the utility of five sequential steps constituting the Collage Life Story Elicitation Technique(CLET)for scaffolding storytelling among children in middle childhood(aged 9-12 years).Using the CLET for data collection and conducting an interpretive analysis,the researchers explored the performance of 38 middle-childhood children living in three different settings.Findings suggest that the five sequential steps of the CLET adequately and satisfactorily combine to stimulate and elicit rich data and help children to construct their narratives and represent the challenges they face in everyday living.We discuss the application of CLET in SBFC practice as tool when screening and intervention planning for children’s perspectives pertaining to a range of topics regarding each of the four quadrants as proposed in the SBFC metamodel.

The Use of an Elicited Imitation Test to Measure Global Oral Proficiency of L2 Chinese at the Postsecondary Classroom Level

With a growing number of foreign language studies on proficiency outcomes,it is imperative to address the challenge of measuring students’proficiency development in a language program where standardized proficiency testing is not readily available.This article reports administering a Chinese elicited imitation test(EIT)by an instructor to track students’global oral proficiency development in a small language program in a mid-size U.S.public university.The test results from the EIT of second language(L2)Chinese suggest that this tool can provide the instructor with valuable insights into students’oral proficiency.This study also discusses the potential practical value of using this EIT in a language program with limited resources for standardized proficiency assessment.The hope is that this study will encourage language educators who are not already doing so to start using empirical evidence from a valid and reliable proficiency measurement tool to reflect on,improve,and guide their instructional practices.
