Plant Endophytes and Epiphytes: Burgeoning Sources of Known and “Unknown” Cytotoxic and Antibiotic Agents?
Authors: Newman David J. , Cragg Gordon M. 
Published: February 2020

AbstractIn the last 20 or so years, the influence of endophytes and, quite recently, epiphytes of plants upon the compounds found in those plants, which were usually assumed to be phytochemicals produced by the plant for a variety of reasons, often as a defense against predators, is becoming more evident, in particular in the case of antitumor agents originally isolated from plant sources, though antibiotic agents might also be found, particularly from epiphytes. In this review, we started with the first report in 1993 of a taxol-producing endophyte and then expanded the compounds discussed to include camptothecin, the vinca alkaloids, podophyllotoxin, and homoharringtonine from endophytic microbes and then the realization that maytansine is not a plant secondary metabolite at all, and that even such a well-studied plant such as Arabidopsis thaliana has a vast repertoire of potential bioactive agents in its leaf epiphytic bacteria. We have taken data from a variety of
sources, including a reasonable history of these discoveries that were not given in recent papers by us, nor in other papers covering this topic. The sources included the Scopus database, but we also performed other searches using bibliographic tools, thus, the majority of the papers referenced are the originals, though we note some very recent papers that have built on previous results. We concluded with a discussion of the more modern techniques that can be utilized to “persuade” endophytes and epiphytes to switch on silent biosynthetic pathways and how current analytical techniques may aid in evaluating such programs. We also comment at times on some findings, particularly in the case of homoharringtonine, where there are repetitious data reports differing by a few years claiming the same endophyte as the producer.
Feline Distal Tibial Physeal Fracture Repair Using a Modified Cross-Pin Technique with Four Pins
Authors: Miraldo Diogo , Salmelin Bettina , Yeadon Russell 
Published: February 2020

Abstract
Objective The aim of this article was to report the surgical technique and clinical outcome of a modified cross-pin technique for the treatment of distal tibial physeal fractures in cats without postoperative external coaptation.
Study Design This study was a retrospective clinical study.
Animals A total of 9 cats were presented with fracture of the distal tibial physis.
Materials and Methods Medical records from July 2014 to September 2018 were reviewed. In all cases, a second medial and a craniolateral Kirschner wires were added to the traditional cross-pin technique. Information reviewed included orthogonal radiographs pre- and post-surgery and at subsequent re-examinations, subjective assessment of lameness and passive range of motion, veterinary clinical assessment and completion of a functional questionnaire (feline musculoskeletal pain index) at the time of writing this report. Eight owners completed the questionnaire. The mean questionnaire follow-up time was 12.7 months.
Results Uncomplicated fracture healing occurred in all patients. Two patients required implant removal due to Kirschner wire migration and protrusion through the skin at 5 and 12 months post-surgery. No other complications were noticed. Eight patients had an excellent outcome, and one patient had a good outcome.
Conclusion Distal tibial physeal fractures in cats can be treated successfully with the use of a modified cross-pin technique and without the use of external coaptation. Prognosis should be considered favourable for this type of fracture.

Abstract
Background Replantation of a single digit at the distal phalanx level is not routinely performed since it is technically challenging with questionable cost-effectiveness. The purpose of this study was to analyze international microsurgeons' clinical decisions when faced with this common scenario.
Methods A survey of a right-middle finger distal phalanx transverse complete amputation case was conducted via online and paper questionnaires. Microsurgeons around the world were invited to provide their treatment recommendations. In total, 383 microsurgeons replied, and their responses were stratified and analyzed by geographical areas, specialties, microsurgery fellowship training, and clinical experiences.
Results Among 383 microsurgeons, 170 (44.3%) chose replantation as their preferred management option, 137 (35.8%) chose revision amputation, 62 (16.2%) chose local flap coverage, 8 (2.1%) chose composite graft, and 6 (1.6%) favored other choices as their reconstruction method for the case study. Microsurgeons from the Asia-Pacific, Middle East/South Asia, and Central/South America regions tend to perform replantation (70.7, 68.8, and 67.4%, respectively) whereas surgeons from North America and Europe showed a lower preference toward replantation (20.5 and 26.8%, respectively p < 0.001). Having completed a microsurgery fellowship increased the attempt rate of replantation by 15.3% (p = 0.004). Clinical experience and the surgeons' specialties did not show statistical significance in clinical decision making.
Conclusion From the present study, the geographic preferences and microsurgery fellowship experience influence the method of reconstruction for distal phalanx amputation. Multiple factors are taken into consideration in selecting the most suitable reconstructive method for each case scenario. In addition to the technical challenges of the proposed surgery, the cost of the procedure and the type of facility needed are important variables in the decision making process.

Published: February 2020

AbstractGiant serpentine aneurysm (GSA) with rare aortic and supra-aortic vascular anomaly is technically difficult to treat. Often such patients suffer without treatment. We have treated a patient by a different approach which is not regularly followed. This case has many developmental anomalies with complicated anatomy, and it is a challenge to the treating interventionist.
Neonatal Polycythemia and Hypoglycemia in Newborns: Are They Related?
Authors: Hopfeld-Fogel Adi , Kasirer Yair , Mimouni Francis B. , Hammerman Cathy , Bin-Nun Alona 
Published: February 2020

AbstractObjective This study aimed to test whether neonatal hypoglycemia (NH) is more common in infants with neonatal polycythemia (NP).Study Design This is a retrospective study based on universal screening of NH and targeted screening for NP. Polycythemia was defined as venous hematocrit ≥ 65%. NH was defined as whole blood glucose (BG) concentration < 48 mg/dL (measured using a “point-of-care” analyzer [Accu-Chek]).Results The study population consisted of 119 consecutive term polycythemic infants and 117 controls. There were no significant differences between the two groups in perinatal characteristics, minimal BG concentration, and rate of hypoglycemia. In a stepwise backward multiple regression where NH was the dependent variable, only maternal gestational diabetes mellitus (p = 0.032) and toxemia (p = 0.001) remained significant, whereas NP was insignificant.Conclusion NH is not more common in NP infants than in non-NP infants. We suggest that the occurrence of NH in infants with NP might be related to the common risk factors of the two morbidities.
A corpus-based exploration of constructions in written academic
English as a lingua franca
Authors: Yilmaz Selahattin , Römer-Barron Ute 
Published: February 2020

Abstract
With English being the global language of
research, academic English as a Lingua Franca (ELF) research has
gained wide recognition. While early research showcased the dynamic
nature of spoken academic ELF, written academic ELF, a more recent
focus of research, remains to be under-studied. However, not only
are there known differences between speaking and writing, writing is
also the dominant mode of reporting new research in academia.
Situated within usage-based Construction Grammar (CxG), the present
study aims to identify constructions in written academic ELF in
comparison to American academic writing. Our methodological
approach, which combined a key word analysis with systematic
explorations of fixed and variable phraseological items in a corpus
of ELF academic writing, leads to the identification of
constructions that are characteristic of written academic ELF.
The influence of sources on First-Year Composition L1 student
writing
Authors: Doolan Stephen M. 
Published: February 2020

Abstract
Writing from sources is a necessity for academic
writing, but it is especially challenging for First-Year Composition
(FYC) writers (Horning &
Kraemer 2013; Serviss
& Jamieson 2017). Yet, few studies have empirically
investigated the source-based language use features of FYC writers.
For this study, English as a first language (L1) FYC students
(N = 232) wrote in-class essays using two
source readings. A multi-dimensional analysis on 13 linguistic
features associated with the presence or absence of source use
(e.g., reporting verbs, titles and authors, personal pronouns) was
conducted, resulting in three dimensions, (1) Source-Based Concept
Density vs. Prompt-Based Freewriting, (2) Impersonal Extension of
Source-Based Concepts, and (3) Source Text Deixis. Implications of
these dimensions for source-based student writing are discussed.
The use of lexical patterns in engineering
Authors: Nekrasova-Beker Tatiana , Becker Anthony 
Published: February 2020

Abstract
Over the past decade, engineering has been one
of the most oft-chosen fields of study for domestic and
international students at US colleges and universities (IIE 2017; NCES 2018). As a result,
the number of students in undergraduate engineering courses has
steadily grown, leading to increased attention devoted to the
written discourse encountered in engineering courses. The present
study investigates the linguistic overlap between published
textbooks used in lower-division undergraduate engineering courses
by focusing on the analysis of multi-word sequences – 5-word
phrase-frames – commonly found in five engineering disciplines.
Overall, it was found that, while frequency distribution and
structural characteristics of the identified phrase-frames were
consistent across the five corpora, there were dissimilarities in
the discourse functions performed by these patterns.
Stand-alone literature reviews
Authors: Wright Heidi R. 
Published: February 2020

Abstract
This chapter presents a new multi-dimensional
analysis of stand-alone literature reviews (e.g., Annual
Review of Medicine). Using the methods of Biber (1988), I analyzed
417 stand-alone literature reviews. A factor analysis of 72
grammatical features was conducted and a six-factor solution chosen.
The dimensions were interpreted as Human vs. Technical/Academic
Focus, Questioning/ Interpreting vs. Knowledge-Conferring,
Expression of Stance, Author/Discourse Community vs. Topic Focus,
Abstract vs. Concrete Focus, and Methodological Concerns vs.
Description. Texts were then divided into four groups: discipline,
time period, review type, and the presence or absence of methods.
Factorial ANOVAs found significant differences for discipline and
time period for many dimensions, whereas significant differences for
presence of methods and review type were limited to one dimension
each.
A multi-dimensional view of collocations in academic
writing
Authors: Zuppardi Maria Carolina , Berber Sardinha Tony 
Published: February 2020

Abstract
This chapter discusses the identification of the
major sets of interrelated collocations in academic writing across
different disciplines, or dimensions of collocation. A corpus of
textbooks and research articles from Social, Behavioral and Economic
Sciences, containing 10.6 million words across 230 texts was
analyzed using a collocational multi-dimensional analysis framework
(Berber Sardinha
2017). Results show four dimensions of collocation for
Social, Behavioral and Economic Sciences, namely: (1) Human Nature,
Culture and Research Methods vs. Economics; (2) Human Evolution and
Society; (3) Business and Finance; and (4) Statistics. The chapter
highlights a methodology for identifying collocational patterns
through multi-dimensional analysis, and contributes to a better
understanding of academic writing in Social, Behavioral and Economic
Sciences.
How are translation norms negotiated?
Authors: Hu Bei 
Published: February 2020

AbstractTranslation norms are conventionally viewed as forces that regulate translatorial behavior. Yet little is known about how norms are validated, challenged or broken by human agents. This quasi-experimental study of Chinese institutional translation proposes a risk-management model that explains how norms are jointly negotiated among the agents embedded in different institutional milieus. It is argued that norms are validated by the translators who strategically manage and weigh various translation risks pertaining to both the start and target cultures.

The optimized allocation of emergency resources for power system restoration
Authors: Liang H P , Li Y , Wang X M , Liu Y P 
Published: February 2020

Abstract
In recent years, there have been frequent blackout accidents in foreign countries. For power system, the configuration of emergency resources affects the process of the power system restoration. It is the key to ensure the smooth restoration of power system that the emergency generating vehicle and the operations staff arrive at the substation in time after the blackout. In this paper, the optimal allocation scheme of the emergency generating vehicle considering the comprehensive importance of load nodes and traffic network constraints is proposed. The comprehensive importance degree of nodes is calculated by considering the spectral importance degree, the importance degree of load amount and the comprehensive importance degree of load of nodes. The blackout economic loss of node is evaluated by node’s comprehensive importance degree. In addition, the cost of configuration and maintenance of the emergency generating vehicle and the transmission cost under the constraint of traffic network are considered to establish the optimal configuration model of the emergency generating vehicle. Finally, the Discrete Binary Particle Swarm Optimization (DBPSO) is used to obtain the optimal configuration location of emergency generating vehicle and the optimal route for recovery. The validity and feasibility of the proposed method are verified by the results of IEEE39.

Published: February 2020

Abstract
The take-off and landing signal light is an integral part of the ship’s helicopter surface-assisted lighting system and light attenuation under special weather conditions are different. In this paper, the light color performance of an actual take-off and landing signal light are tested and the transmission characteristics under special weather conditions are analyzed. The methods of increasing the forward current and turn on the standby light source are studied. In this paper, the mathematical relationship between increasing current and increasing transmission distance is studied. The calculation of the example shows that the variation of the transmission distance of the take-off and landing signal by changing current is effective to adapt to weather conditions. For an example, the transmission distance of the given lamp is increased about 300 meters when the current is increased from 350 mA to 400 mA in sunny weather.

Published: February 2020

Abstract
In order to overcome the shortcomings of half-angle reflectors mechanism stabilization configuration, we study the Line-of-Sight (LOS) of reflectors reconstruction and stabilization technique. A LOS reconstruction and stabilization configuration of reflectors is designed and modeled. Firstly, we design the Fastest Differential Tracker (FDT) to estimate relative angular rates, then propose a two-coordinate modeling method that is easy to analyse disturbance isolation performance, thirdly we study the control system isolation deegree to the measurement noise and carrier disturbance. The simulations indicate that FDT has superior performance in tracking speed, noise suppression and steady state vibration suppression, and that the stabilization accuracy, in consideration of both noise and carrier disturbance, is about 70μrad(1σ). The experimental results show that reflector platform stabilization accuracy based on LOS reconstruction configuration is about 80μrad(1σ).
