The paper proposes two new efficient algorithms, implemented by a short program code in MS Excel, designed to identify and characterize the sizes of nano- and micropowders of particles in the form of generalized gamma or lognormal distributions according to experimental histograms. The proposed method is a new general approach to solving inverse problems of identifying the parameters of differential distribution functions from experimental data based on minimizing the functional that is the coefficient of determination.The algorithm is implemented with formulas (less than 10) of the most common tools (MS Excel spreadsheets without the use of macros), which allow researchers without the skills of professional programmers to easily check and reproduce the presented material, as well as the ability to modify the code to solve a wider range of problems. The text of the article and comments on the worksheets of screenshots represent ready-made instructions for solving problems of identification of distribution functions and characterization of the sizes of nano- and micropowders.

Adding Matrix Control: Insertion-Deletion Systems with Substitutions III

Insertion-deletion systems have been introduced as a formalism to model operations that find their counterparts in ideas of bio-computing, more specifically, when using DNA or RNA strings and biological mechanisms that work on these strings. So-called matrix control has been introduced to insertion-deletion systems in order to enable writing short program fragments. We discuss substitutions as a further type of operation, added to matrix insertion-deletion systems. For such systems, we additionally discuss the effect of appearance checking. This way, we obtain new characterizations of the family of context-sensitive and the family of recursively enumerable languages. Not much context is needed for systems with appearance checking to reach computational completeness. This also suggests that bio-computers may run rather traditionally written programs, as our simulations also show how Turing machines, like any other computational device, can be simulated by certain matrix insertion-deletion-substitution systems.

Adaptive True Proportional Navigation Guidance Based On Heuristic Optimization Algorithms

The PN-guidance (Proportional Guidance) still continues to be improved, because it is the simplest, cheapest and most reliable algorithm. One of the most important techniques to improve PN-guidance is to adapt the navigation constant depending on time. In this study, first, the entire adaptation methods for PN-guidance are classified, then the adaptation process is online achieved by using heuristic optimization during guiding the missile. The novelty of this study is that the heuristic optimization approach is used at the first time to update the navigation constant of PN-guidance. It is considered that having short program code, fast convergence speed and just simple algebraic computations without derivative are vital advantages of heuristic algorithms using into missile systems. In this scope, an Adaptive True-PN (ATPN) guidance algorithm is designed by optimizing navigation constants varying according to the target behavior. The results show that while the acceleration gap of the pitch axis decreases 21.8%, the acceleration gap of yaw axis reduces 39.68%. These reductions mean that while the missile guided by ATPN is maneuvering, it is exposed to less acceleration and less strain.

HbE Variants: An Experience from Tertiary Care Centre of Eastern India

Background- HbE is the second most common structural haemoglobin disorder after sickle cell haemoglobin (HbS). Haemoglobin E (HbE) is variant haemoglobin with a mutation in the globin gene causing substitution of glutamic acid for lysine at position 26 of the globin chain. Aims & Objectives- 1) To Know demographical parameters of HbE variants and 2) To know the Hematological parameters of HbE variants. Materials & Methods- The present single-centre, retrospective, cross-sectional study was carried out on consecutive 2035 Hb-E variants who were screened by CE-HPLC for hemoglobinopathies in the Thalassemia control unit (TCU) in our tertiary care referral centre after obtaining the proper approval from ethical committee of the institution and informed consent from the patients. The evaluation was done in Bio-Rad Variant Haemoglobin Testing System (Hercules, California, USA) using variant b-thalassemia short program pack. All the analyses were done using IBM SPSS statistics software, version 19 and MedCalc software, version 12.3.0.0. Result- Among 2035 subjects’ majority (80%) were diagnosed as HbE carrier. Age ranged from 1 year to 75 years with mean of 19.1±13.2 years. Study population mostly comprised of antenatal mothers (23.2 %) followed by premarital (20.2%), children (18.1 %), post marital (17.4%), %), family member of affected person (16.6%), suspected patient (3.5 %) family member of carrier (0.2%) and others (0.8%). Conclusion: HbE disorders are paradox: its behaviour ranges from good, bad to ugly and the value of HbE does not correlate with the severity of the diseases.

Introduction

This chapter is a self-contained tutorial which tells you how to get started with parallel programming and how to design and implement parallel algorithms in a structured way using supersteps. It introduces a simple target architecture for designing parallel algorithms, the bulk synchronous parallel (BSP) computer. Using the computation of the inner product of two vectors as an example, the chapter shows how an algorithm is designed, hand in hand with its cost analysis. The inner-product algorithm is implemented in a short program that demonstrates the most important primitives of the communication library, BSPlib. Furthermore, a benchmarking program is given for measuring the BSP parameters of a parallel computer. Its use is demonstrated on a desktop computer and a supercomputer. Finally, a parallel regular sampling sort algorithm is presented, implemented, and tested.

THE CASTLE OF ACHANDUIN, LISMORE—A POINT OF REFERENCE FOR THE RADIOCARBON ANALYSIS OF MORTAR-ENTRAPPED RELICT LIMEKILN FUELS

ABSTRACT The results of a short program of landscape, buildings and materials analysis undertaken at Achanduin Castle, Lismore, Scotland (NM 8043 3927) are presented from the pilot phase of the Scottish Medieval Castles & Chapels C14 Project (SMCCCP). The study presents the first independent chronological evidence relating to the construction of this important medieval building, by radiocarbon analysis of a limited assemblage of Mortar-Entrapped Relict Limekiln Fuel (MERLF) fragments. Informed by a wider investigation of structural phasing and sample taphonomy, these measurements are constrained within a series of different Bayesian models, to generate a range of comparative estimates for the building’s constructional chronology. The precision with which the construction of this building can now be dated, from other evidence associated with the site, makes the Achanduin Castle study a useful point of reference for wider materials research.

Empowering the Peer Group to Prevent School Bullying in Kosovo: Effectiveness of a Short and Ultra-Short Version of the ViSC Social Competence Program

Evidence-based anti-bullying programs are predominantly implemented in high-income countries, although there is a clear need for bullying prevention also in low- and middle-income countries. The present study reports the effectiveness of a short and ultra-short version of the ViSC Social Competence Program that was implemented in nine Kosovar schools. The ViSC program aims to empower adolescents to recognize bullying and to intervene in bullying situations. A quasi-experimental longitudinal control group design was realized to examine the effectiveness of the two program versions regarding different forms of self-reported perpetration and victimization. The short program version was implemented in 10 classes (N = 282, 52% girls, Mage = 13.45), the ultra-short program version was implemented in 13 classes (N = 354, 46% girls, Mage = 13.28), and 23 classes (N = 613, 50% girls, Mage = 13.31) served as control group. Multilevel growth models revealed intervention effects in favor of the ultra-short version when compared to the control group regarding physical victimization. All other effects were not significant. To conclude, educational and social policies supporting the implementation of evidence-based anti-bullying programs need to be issued in low- and middle-income countries, as even ultra-short versions might be effective in contexts with limited available resources.

Teaching Requesting to EFL Learners: A Conversation Analysis-Informed Approach

Requesting can be a difficult speech act for EFL learners. However, current classroom materials do not always provide effective guidance, frequently lacking explicit instruction or failing to embed requests in wider conversations. Conversation analysis (CA), focusing on requesting in authentic talk, has been proposed as a potential resource for the EFL classroom. In the current study, the effectiveness of CA-informed classroom instruction in promoting development in learner requesting was investigated, focusing on a single participant. There were 3 study phases—a preprogramme set of requesting tasks; a short program of instruction, informed by the CA literature; and a further set of requesting tasks. Pre-and postprogramme transcript data and requesting models drawn by the participant were analysed. Postprogramme requesting performances were found to generally be more complex, with lengthier opening, requesting, and closing sequences. Learner requesting models also showed evidence of developing understanding of how requests are co-constructed in conversation. EFL学習者にとって、依頼行為は、難しい発話行為となりえる。しかしながら、授業で使用する教材は、効果的なガイダンスが提示されていないことがあり、明白な指示もしばしば不足し、また様々な会話での依頼行為を盛り込めていない。会話分析（CA）は、実際の会話での依頼行為にフォーカスし、EFLの授業のリソース候補として提唱されてきた。本論文では、CAに基づく授業指導の有効性を探っている。今回のCAは一人の実験参加者に着目し、3段階に分けて調査した。指導前の依頼行為、CA研究に基づく短かい指導、指導後の依頼行為である。そして、指導前後の会話データと、実験参加者が描いた依頼の会話チャートを分析した。指導後は、依頼行為が全体的により複雑化し、会話の始まり、依頼、そして結びまでが長くなることが判明した。また、学習者が描いた依頼の会話チャートでも、会話での依頼行為の（参加者による）共同の組み立て方をより理解した形跡が見られた。

Wellness in Allied Health students: the case for change

Introduction: the case for changeThere are increasing mental health issues among young people, including higher education students. Millennial students face unique challenges with attention, critical thinking and managing stress. In addition, allied health students engage in multiple placements where they need to interact with real people in real time whilst being evaluated in assessment and treatment strategies. Some universities have been using wellness programs and mindfulness strategies to support student mental health across campuses for some time. However, as allied health students face unique challenges, there is a need for a particular focus on wellness at an individual allied health course level. The curriculum in allied health courses is determined by accreditation bodies and is comprehensive with little space for additional information. It is possible for short activities to be embedded in tutorials and the authors argue a focus on wellness is vital for the future allied health workforce.Methodology for pilot projectThis project used questionnaires to investigate student perceptions of a short program of activities to promote wellness and mindfulness in third year speech pathology students who were also engaging in clinical placements.Results and discussionStudents were positive about the activities, developed their own wellness plan and learnt new strategies to manage their mental health at university and in their future careers.Future directionsThis short program could easily be adapted in other allied health courses.
