Improving Software Development Effort Estimation with a Novel Design Pattern Model
Authors: Subbiah Chidambaram , Hupman Andrea C. , Li Haitao , Simonis Joseph 
Published: September 2022

A U.S. Midwestern Fortune 500 financial services firm develops software capabilities in-house and requires predictions of project needs for efficient resource allocation decisions across the many projects operating simultaneously. The company develops a novel prediction tool based on the projects’ required software development tasks as described by firm-specific design patterns. The firm provides these predictions within a set of estimates based on industry standard function count methods as well as firm-specific predictive models based on function points and on initial labor assignments. Company management is thus equipped with predictions from multiple methodologies and multiple information sources, enhancing the firm’s ability to predict project needs. Managers aggregate the forecasts, with prediction performance estimated to improve by 35%–49%, measured relative to estimates of the absolute percentage error of the prior method. The improved predictions provide a significant advantage to planning decisions and efficient internal operations. Insights to how managers aggregate the set of forecasts and insights to how the models contribute to the scaled value of information are discussed and further illustrate the benefits of the approach.

Platelet-rich fibrin accelerates skin wound healing in pressure injuries: a rat model
Authors: Zhang Tao , Wang Jia , Le Kai , Guo Yifan , Zhu Bin 
Published: September 2022

Objective: Platelet-rich fibrin (PRF) plays a role in promoting wound healing by releasing cytokines, chemokines and growth factors, and by inducing proliferation and activation of cells. A pressure injury (PI) is a treatable but serious and costly disease with adverse outcomes for the patient. However, traditional PI treatments are time-consuming, with limited effectiveness. Thus, we aimed to investigate the effects and mechanisms of PRF on skin wound healing in PIs in vivo in a rat model. Method: PRF was prepared from the blood of male Wistar rats. A rat model for PI ischaemia/reperfusion injury was established by placing a magnet onto the back skin, where a magnetic steel plate had been previously implanted. The rats were randomised into two groups: the control group was treated with sterile gauze dressings and the iPRF group received additional PRF. Skin wound healing rate was calculated and a CD31/Masson's trichrome stain performed. Results: In this study, 16 rats were allocated to the two groups (n=8 in each group). PRF improved the skin wound healing rate of PIs in the rats; haematoxylin and eosin staining and CD31 staining showed that the number of capillaries increased significantly in the wound. However, Masson's trichrome staining showed no increase in fibrotic tissues after PRF treatment. Conclusion: In this in vivo rat model for PI, PRF accelerated skin wound healing by increasing angiogenesis in the wound.

Combined effects of high irradiance and temperature on the photosynthetic and antioxidant responses of Thalassia hemprichii and Halophila ovalis
Authors: Saewong Chanida , Soonthornkalump Sutthinut , Buapet Pimchanok 
Published: September 2022

Abstract
During midday low tides, tropical intertidal seagrasses are challenged by high irradiance and high temperature. This study assessed photosynthetic and oxidative stress responses of Thalassia hemprichii and Halophila ovalis exposed to 150 and 1000 μmol photons m−2 s−1 and 30 and 40 °C for 3 h. High temperature (40 °C) significantly decreased the maximum quantum yield of both seagrasses and this heat-induced photoinhibition was exacerbated by high irradiance (1000 μmol photons m−2 s−1). High irradiance also aggravated the effects of high temperature on the effective quantum yield of T. hemprichii. Non-photochemical quenching (NPQ) of T. hemprichii was induced by both stressors with no additive effects. In contrast, NPQ of H. ovalis was induced under high irradiance at 30 °C but was inhibited at 40 °C. Nevertheless, antioxidant enzyme activity and reactive oxygen species content did not differ among treatments in either seagrass. Monitoring chloroplast distribution in H. ovalis revealed a partial inhibitory effect of high temperature on chloroplast avoidance movement under high irradiance. Our results suggest that warming events may cause detrimental impacts on shallow water seagrasses. Halophila ovalis may be more vulnerable than T. hemprichii as its photoprotection, i.e. NPQ and chloroplast avoidance movement, was hindered at high temperature.
How do L1 Chinese raters process the L2 Chinese speech signal at the sentence level with respect to accentedness, comprehensibility and intelligibility?
Authors: Neal Robert 
Published: September 2022

Abstract
Set within the context of teaching and learning Chinese at two secondary schools in the North of England and adopting a case study research design, the aim of this study was to develop research-informed insights into the nature of the pronunciation challenges facing beginner learners of Chinese. Data collection activities included recording the spoken Chinese of 20 L2 learners during a read-aloud task and a question-answer activity. Forty L1 raters were subsequently interviewed as they rated and transcribed the learners’ randomized speech samples. Distinguishing between the key constructs of accentedness, comprehensibility and intelligibility, it was found that heavily accented tones did not necessarily lead to lower levels of comprehensibility and intelligibility. Furthermore, many intelligibility breakdowns – i.e. when raters failed to correctly transcribe the learners’ intended utterances – could be traced to problems with individual words which usually implicated segmental sounds as well as tone. Findings are interpreted in terms of indicating a need for more nuanced classroom priorities aimed at the promotion of intelligible speech as opposed to an unrealistic focus on developing a native-like accent.

Some people and personalities of organic chemistry: a teaching hook for mid-level university students
Authors: Mackey Katrina , McHugh Martin , McGlacken Gerard P. 
Published: September 2022

Abstract
Organic chemistry often represents a key impasse for students during their third level science education. Both intrinsic and extrinsic factors contribute to perceived difficulties in learning the subject. Moreover, the teaching of multi-step organic synthesis at third level has well-documented challenges. At University College Cork (UCC), we have adopted a strategy to engage students at the mid to late degree stage using an innovative teaching hook, to inspire interest and engagement. The approach was taken to outline chronologically some of the seminal breakthroughs in synthesis, and organic chemistry more generally, from the 1950 s to a few of the current leaders of today. Importantly the focus is on the people, the circumstance and the stories surrounding them. As a relevance-based hooking strategy grounded in a storytelling pedagogy, the goal was to inform students of the potential in organic chemistry and thus spark their interest for the subsequent lectures. Over multiple interventions, feedback from students has been highly positive. We posit that the design framework behind the ‘The People and Personalities’ could be adapted to many disciplines in a similarly successful manner. Overall, this approach proved inspirational for students, and was a most timely intervention in their degree program.
A modified seven-level cross-connected PUC boost multilevel inverter with reduced cost factor and device count
Authors: Phukan Hillol , Debela Tamiru , Singh Jiwanjot 
Published: September 2022

Abstract
The device count (dC) and cost factor (CF) with the boosting feature are the main challenges in the packed u-cell multilevel inverters as the number of levels are increased in the output voltage. In this paper, to mitigate these problems, a new topology of a 7-level modified packed u-cell boost multilevel inverter (PUC-BMLI) is designed to improve the cost factor and device count. Further, it can be used for a wide range of switching frequencies since only one capacitor is required and the voltage across the capacitor is balanced. To generate a 7-level stepped-up voltage across the load, the PUC-BMLI needs only eight power switches and one capacitor. The proposed topology can boost the input voltage by 1.5 times. To generate a 7-level stepped-up voltage across the output multicarrier phase-disposition pulse width modulation (PD-PWM) has been used. To prove the superior performance of the PUC-BMLI, a comparative analysis with existing single DC source boost MLI has been done. The device count (dC) and cost factor (CF) are the lowest compared to the recently proposed topology employing one dc source and producing 7-level across the output. The dC and CF are 10 and 22.33. All the switches are two-quadrant switches, thus reducing the cost of the overall circuit. THD is found to be 4.10% for output current. The feasibility of the 7-level modified topology is evaluated by Matlab/Simulink simulation and verified by an experimental study using the OPAL-RT 4510 real-time platform.
Tu quoque?! On the second person pronoun tusya (tus̱a) and the second person verbal ending -tu (-du) in Niya Prakrit
Authors: Schoubben Niels 
Published: September 2022

Abstract
When compared to Old Indo-Aryan (OIA) and other Middle Indo-Aryan (MIA) languages, the marking of the second person in Niya Prakrit differs in two crucial respects. On the one hand, Niya Prakrit makes use of a pronoun tusya/tus̱a ‘you’ that is not found in the other languages. On the other hand, Niya Prakrit has a verbal ending -tu (-du) as a second person marker on top of the old 2sg ending -si (-s̱i) and the 2pl ending -tha. This paper argues that these two peculiarities are related to one another and that both the pronoun and the verbal ending have not been properly described in earlier scholarship. First, it will be claimed that tusya (tus̱a) is not a genitive singular (gen.sg), as previously thought, but a direct plural (dir.pl). As a consequence, a new etymology for this pronoun will be offered too. Second, this article presents various arguments that -tu (-du) is not a 2sg ending, but a 2pl.

Application of programmable logic control in the nonlinear machine automation control using numerical control technology
Authors: Zhang Lei 
Published: September 2022

Abstract
To explore the application of programmable logic control (PLC) in the automatic control of nonlinear machine tools, the application of PLC in the nonlinear electronic system control is studied. First, the author takes PLC technology in the numerical control machine tool electrical control application as the research equipment, PLC technology in the numerical control machine tool electrical control application is divided into four types. Then, according to the need of management number, the overall structure of PLC is designed and developed, and the concept of operation modularization is adopted to realize the decentralized development of PLC. There are three functional modules: repair, compile, and simulate. Finally, the machining performance of the nc system is evaluated experimentally. The processing time difference of two kinds of machine tools is compared. The average processing time of the original (Numerically controlled) NC system is 3.06 s, and the average processing time of the embedded soft PLC system is 2.01 s, with a gap of 1.04 s between the two systems. The Computer Numerical Control (CNC) machining improvement of 1 s is significant in the processing efficiency of CNC machine tools. The numerical control system embedded in the PLC system is more stable in the machining time, so it can be concluded that the numerical control-embedded soft PLC system has carried on some improvements and upgrades to the operation of machine tools. PLC has relatively strong reliability, stability, and flexibility and is widely used in industrial control systems. In the production process of CNC machine tools, the application of PLC can improve the automatic control level of machine tools. The application of PLC can improve the automatic control level of machine tools and realize the effective control of each link in the production process of CNC machine tools, such as the start-stop program, the automatic replacement of cutting tools in the production process, the automatic diagnosis, and treatment of various faults in the production process, which can be realized through the application of PLC technology.
Online media and global communication research in Nigeria
Authors: Mojaye Eserinune McCarty , Ogunyombo Oludare Ebenezer 
Published: September 2022

Abstract
The growth of global online media necessitates a better knowledge of how these media affect the world. Communication researchers have examined how rhetoric and globalization interact dynamically; how information spreads through cross-cultural interactions, and how a growing global media landscape affects culture, society, economy, and politics. However, no study has aggregated the areas of focus of such studies in order to establish a trend of the discussion of online media and global communication scholarship in Nigeria. In this essay, we offer a pathway for understanding approaches to scholarship in online media and global communication in Nigeria. We review all articles on online media and global communication that were published in two Nigerian academic journals, The Nigerian Journal of Communication and the Journal of Communication and Media Research between 2015 and 2021 using our content categories of authorship, theory/theories used, study population, method of study and research focus. We found that social media, which has proved to be a very hot area of research among scholars worldwide, also occupied the pride of place among Nigerian scholars and that collaboration in research, which is a major way of growing and advancing knowledge, was also significantly common among Nigerian communication researchers. On the low side, however, we found, among others, that lack of funding was a major issue in Nigerian communication research as none of the 73 articles that we analyzed was funded.
Concurrent Validity Between Potential Screening Tests for Early Mobility Decline in Independent Community Dwellers
Authors: Yoshida Yuri , Zeni Joseph A. , Zhu YiLiang , Rhyne Robert L. 
Published: September 2022

Background and Purpose:
Standardized screening tests that detect early mobility decline, regardless of etiology, are needed for healthy aging. The locomotive syndrome (LS) tests are designed to identify stages of mobility decline and inform appropriate levels of intervention. The long-term goal of this research is to develop standardized mobility screening tests that can be used across health care settings and throughout a patient's lifespan to guide appropriate medical care. As the first step in this process, this study examines the concurrent validity between the reference and the LS tests.

Methods:
This cross-sectional study examined correlations between the LS functional tests and a set of reference tests and the ability to differentiate the 3 stages of mobility decline. The reference tests included the stair-climbing test, the 30-second chair rise test, the 6-minute walk test, the Global Physical Health (GPH) portion of the PROMIS, and the Lower Extremity Functional Scale (LEFS). The LS tests included the Stand-Up Test, the 2-Step Test, and the 25-question Geriatric Locomotive Function Scale (25-GLFS). A total of 115 community dwellers of 61.2 years old on average (±10.0 years), with n = 71 (61%) older than 60 years, voluntary participated in this prospective study. Nonparametric analyses of variance and correlations were used to examine the concurrent validity.

Results and Discussion:
Performance-based tests were significantly correlated (|r | = 0.38-0.61, P < .001) with LS tests. The LEFS was correlated with all LS tests, but the GPH was only correlated with the 25-GLFS. Also, significant differences were found in reference test scores between the 3 LS stages (P < .05).

Conclusions:
The LS tests and reference tests demonstrated significant correlations, and participants performed significantly worse on reference tests as LS severity increased. Given these results, it is possible that the LS standardized tests may play an important role in mobility screening. Future research should investigate feasibility, sensitivity, and specificity of these tests.
Optimization of Parameters of the New Turner-Fairbank Alkali-Silica Reactivity Susceptibility Test (T-Fast)
Authors: Muñoz Jose F. , Balachandran Chandni , Lichtenwalner Ronald L. , Li Zihui , Arnold Terence S. 
Published: September 2022

Abstract
Prevention is an effective strategy to avoid damage caused by the alkali-silica reaction (ASR) in concrete structures. The effectiveness of this strategy heavily depends on the use of reliable accelerated tests to determine if an aggregate used in the concrete has the potential to cause ASR. Recently, a new provisional standard test, AASHTO TP 144-21, Determining the Potential Alkali–Silica Reactivity of Coarse Aggregates (TFHRC-TFAST), has been approved by the American Association of State Highway and Transportation Officials. The test accurately predicted the ASR-induced expansion of aggregates used in more than 50 different mortar and concrete samples, including concrete blocks in outdoor testing facilities and concrete in the field. This manuscript presents the results of the collaborative study among three laboratories conducted as part of an overall effort to standardize the new AASHTO TP 144-21. The objectives of the study were to evaluate the suitability of wavelength dispersive x-ray fluorescence (WDXRF) spectroscopy as the main analytical technique, determine the optimal particle size and effect of moisture on calcium oxide (CaO), and evaluate sample preparation on the results. A total of 18 aggregates were evaluated under the TP 144-21 using 4 different CaO samples and 2 sample preparation protocols. The results indicated that the alkali-silica reactivity of the aggregates can be accurately determined by using WDXRF. Upon exposure to the atmosphere, CaO reacts rapidly with moisture to produce calcium hydroxide [Ca(OH)2]. The particle size distribution and amount of Ca(OH)2 in the CaO influenced the ASR classification of marginal (moderately and slow reactive) and nonreactive aggregates. The researchers obtained optimal results using a reagent grade powder CaO with an average particle size of 4.6 μm and less than 5 % of Ca(OH)2. These conclusions were important to validate and optimize the TP 144-21 protocol before launching a wider interlaboratory study.
Ventrolateral Prefrontal Cortex Contributes to Human Motor Learning
Authors: Kumar Neeraj , Sidarta Ananda , Smith Chelsea , Ostry David J. 
Published: September 2022

AbstractThis study assesses the involvement in human motor learning, of the ventrolateral prefrontal cortex (BA 9/46v), a somatic region in the middle frontal gyrus. The potential involvement of this cortical area in motor learning is suggested by studies in nonhuman primates which have found anatomic connections between this area and sensorimotor regions in frontal and parietal cortex, and also with basal ganglia output zones. It is likewise suggested by electrophysiological studies which have shown that activity in this region is implicated in somatic sensory memory and is also influenced by reward. We directly tested the hypothesis that area 9/46v is involved in reinforcement-based motor learning in humans. Participants performed reaching movements to a hidden target and received positive feedback when successful. Before the learning task, we applied continuous theta burst stimulation (cTBS) to disrupt activity in 9/46v in the left or right hemisphere. A control group received sham cTBS. The data showed that cTBS to left 9/46v almost entirely eliminated motor learning, whereas learning was not different from sham stimulation when cTBS was applied to the same zone in the right hemisphere. Additional analyses showed that the basic reward-history-dependent pattern of movements was preserved but more variable following left hemisphere stimulation, which suggests an overall deficit in somatic memory for target location or target directed movement rather than reward processing per se. The results indicate that area 9/46v is part of the human motor learning circuit.

Published: September 2022

Purpose
Mosaicism is a feature of several inherited tumor syndromes. Only a few cases of mosaicism have been described in multiple endocrine neoplasia type 1 (MEN1). Next-generation sequencing (NGS) offers new possibilities for detecting mosaicism. Here, we report the first study to systematically look for MEN1 mosaicism, using blood DNA, in MEN1-suspected patients but without MEN1 pathogenic variants (PV) in a heterozygous state.

Methods
Digital targeted NGS, including unique molecular identifiers (UMIs), was performed in routine practice, and the analytic performance of this method was verified.

Results
Among a cohort of 119 patients harboring from 2 to 5 MEN1 lesions, we identified 3 patients with MEN1 mosaic PVs. The allele frequencies ranged from 2.3 to 9.5%. The detection rate of MEN1 mosaicism in patients bearing at least 3 MEN1 lesions was 17% (3/18). No cases were detected in patients with two lesions.

Conclusion
We report here three new cases with MEN1 mosaicism. This study examined the performance of UMI in the diagnosis of MEN1 mosaicism in routine practice, and our results underline that the frequency of mosaicism is probably underestimated in patients with suspected MEN1.
