Published: April 2022

AbstractThe cloning between different animals known as interspecific somatic cell nuclear transfer (iSCNT) was carried out for endangered species. The iSCNT has been characterized by a poor success rate due to several factors that influence the formation of the SCNT in various cytoplasms. The cell cycle of the transferred somatic cell, the passage number of the cultured somatic cell, the mitochondria oocytes, and their capabilities are among these factors. This study investigates the role of the passage number of the Arabian Oryx somatic cell culture when transplanted to an enucleated domestic cow oocyte and embryo developmentin vitro. The fibroblast somatic cell of the Arabian Oryx was cultured for several passage lanes (3–13). The optimal passage cell number was found to be 10–13 Oryx cell lines that progressed to various cell stages up to the blastula stage. There was some variation between the different passage numbers of the oryx cell line. The 3–9 cell line did not show a good developmental stage. These could be attributed to several factors that control the iSCNT as stated by several investigators. More investigation is needed to clarify the role of factors that affect the success rate for the iSCNT.
Synergistic effects of PEG middle-blocks and talcum on crystallizability and thermomechanical properties of flexible PLLA-b-PEG-b-PLLA bioplastic
Authors: Srisuwan Yaowalak , Baimark Yodthong 
Published: April 2022

Abstract
In this study, talcum was melt-blended with a flexible poly(l-lactide)-b-polyethylene glycol-b-poly(l-lactide) triblock copolymer (PLLA-PEG-PLLA) with 1, 2, 4, and 8 wt% talcum, for improvement of the crystallization and thermomechanical properties of PLLA-PEG-PLLA compared with PLLA. The crystallizability of PLLA-PEG-PLLA/talcum composites was better than that of PLLA/talcum composites as determined from differential scanning calorimetry. X-ray diffractometry showed that the PLLA-PEG-PLLA/talcum films had a higher degree of crystallinity than the PLLA/talcum films. PEG middle-blocks and talcum showed a synergistic effect for crystallization of PLLA end-blocks. The PLLA-PEG-PLLA/talcum films showed better thermomechanical properties than those of the PLLA/talcum films as determined from dynamic mechanical analysis. This was confirmed from the results of dimensional stability to heat. In summary, the PLLA-PEG-PLLA/talcum composites have potential for use as flexible bioplastics with good dimensional stability to heat.

Abstract
Plant-mediated silver nanoparticles are unique and are considered one of the best nanomaterials used in cancer research. We report a low-cost, eco-friendly process of green synthesis of AgNPs from Commiphora gileadensis stem extracts and evaluated their anticancer potential against colon cancer cell lines HCT-116, HT 29, and SW620. Anticancer activities were performed by an MTT assay and gene expression levels of four genes CHEK1, CHEK2, ATR, and ATM by the real-time polymerase chain reaction. Particles were initially confirmed by UV-visible spectroscopy. The morphology and stability of the particles were examined through TEM, zeta potential, and zeta sizer. GC-MS and FTIR were performed to examine the functional groups. The absorption peak was recorded at 430 nm; the average size recorded by TEM images was 13 nm, while the zeta potential and zeta sizer study showed aggregation in nanoparticles. Compared to C. gileadensis extracts, some of the FT-IR spectrum peaks were sight shifted with some new peaks in C. gileadensis AgNPs. C. gileadensis AgNPs were more toxic against HT29 followed by HTC116 and SW620. Expression levels of most of the genes in HCT116 and HT29 were increased by treatment whereas the gene expression level was least affected in SW620. C. gileadensis AgNPs have anticancer potential and need to be explored in cancer research.
Effect of in situ observation of cooling rates on acicular ferrite nucleation
Authors: Wang Tiantian , Yang Shufeng , Li Jingshe , Guo Hao , Chen Zhengyang 
Published: April 2022

Abstract
The effect of cooling rates on acicular ferrite (AF) nucleation was observed in situ by laser scanning confocal microscopy. The precipitation characteristics of TiN–MnS inclusions, the austenite grain size, and the content and morphologies of AF were analyzed and compared under different cooling rates. The results indicated that with the increase of the cooling rate, the size of TiN–MnS inclusions precipitated in the test steel gradually decreased while the inclusion number increased. When the cooling rate increased from 0.2 to 10°C·s−1, the average inclusion size decreased from 2.7 to 1.3 µm. The austenite grain size decreased gradually with the increase of the cooling rate, and the larger the cooling rate was, the more uniform the grain size distribution. The AF proportion increased first and then decreased, it reached the maximum when the cooling rate was 5°C·s−1, which accounted for 82.6%. Meanwhile, the dendrite size decreased gradually, the average length decreased from 30 to 5 µm, and the average width decreased from 2.8 to 0.7 µm when the cooling rate increased from 0.2 to 10°C·s−1.
Interpretive challenges with American presidential discourse described as joking
Authors: Davies Catherine Evans 
Published: April 2022

Abstract
When an American president speaks in a way that is later characterized as joking/kidding, a wide range of interpretations become possible. At a minimum, there are two basic interpretations: serious and non-serious. At the other extreme, there may be as many nuanced interpretations as there are audiences for the discourse. This study examines the “just/only joking” strategy outside of the face-to-face context and how it has been enacted in relation to presidential discourse. Using as data three prototypical examples for which public interpretations were available, the study explores how the two main audiences (currently polarized political groupings in the United States) tend to interpret the “joking” in relation to the performance style of former President Donald J. Trump either as a harmless joke or as a grave threat.

Die Katastrophe der asketischen Ideale in interkultureller Hinsicht. Wissenschaft, Askese und Nihilismus in GM III 27
Authors: Giacóia Junior Oswaldo 
Published: April 2022

Abstract

The Catastrophe of the Ascetic Ideals from an Intercultural Perspective. Science, Asceticism and Nihilism in GM III 27. This article aims to clarify the meaning and strategic position of the parentheses on the development of philosophy in India in GM III 27. Nietzsche’s reference to the philosophical development in India reveals his intercultural considerations and helps clarify the relations between science and ascetic ideal as a moment of the historical-genealogical reconstitution of European nihilism. I argue that honest forms of atheism and science contain the core of the ascetic ideal and that the critique of nihilism is therefore inevitably self-referential. Nietzsche’s intercultural view sheds new light on important current philosophical questions such as the scope of Giorgio Agamben’s homo-sacer-project and on the prospects of non-European philosophical perspectives.

Published: April 2022

AbstractBamboo is one of the renewable materials which can be applied in the engineering field widely. Previous research has shown that bamboo’s inherent poor durability can limit the application of bamboo materials. And nanotechnology has been receiving more and more attention on improving the properties of natural materials, simultaneously. This article aims to promote the application of nanotechnology on bamboo by presenting some guides. And this article has been organized as follows: first, the characteristics and nanomechanical behavior of bamboo in mesoscopic and nanoscopic scale have been introduced. Then, nanomaterials for modifying bamboo have been presented. Next, some analyses on the improvement of some properties of nano-modified bamboo materials have been made. Finally, future perspectives have been discussed.
Elevated blood lead levels of refugee children in the United States: a systematic review of recent literature (2011–2021)
Authors: Balza Joanna S. , Bikomeye Jean C. , Beyer Kirsten M. M. , Rublee Caitlin , Flynn Kathryn E. 
Published: April 2022

Abstract
Lead is an environmental hazard; even small elevations in blood lead level can cause serious negative health effects in children, including irreversible impacts such as learning difficulties, attention disorders, and behavioral issues. Previous research has shown that some groups are at higher risk for lead poisoning including racial/ethnic minorities, those with low economic status, and immigrants, especially refugees. This systematic review explores recent literature studying disparities in lead poisoning in refugee children. Search terms were chosen with the assistance of a medical librarian, and two independent reviewers assessed articles using a PICOS criteria (Population, Intervention, Comparison, Outcome, Study Design) following the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRIMSA-P) guidelines, a set of evidence-based minimum standards for reporting in systematic reviews. 321 article titles were reviewed, 61 abstracts screened, and 17 methods sections reviewed, ultimately including 13 studies. The studies found a high prevalence of elevated blood lead level among refugee populations when compared to reference populations. Both pre-migration and post-migration factors were identified as contributors to the disparity, and associations were identified between elevated blood lead levels and factors such as country of origin, age, and other health variables. Health providers and resettlement workers should be aware of these disparities and related factors. Testing, care, education and consistent follow-up should be provided.
On the multi-annual potential predictability of the Arctic Ocean climate state in the INM RAS climate model
Authors: Volodin Evgeny M. , Vorobyeva Vasilisa V. 
Published: April 2022

Abstract
Idealized numerical experiments with the INM RAS climate model are used to study the potential predictability of the temperature in the upper 300-meter layer of the Arctic Ocean. It is shown that the heat content can be predictable for up to 4–6 years. Positive anomalies of the temperature and salinity are preceded for several years by a state in which the influx of Atlantic water into the Arctic Ocean exceeds the average value. Surface fields, including temperature, salinity, concentration and mass of ice, are less predictable than the heat content in the layer of 0–300 meters.
Semiotics in South Korea: history and research trends
Authors: Zhang Naiyu 
Published: April 2022

Abstract
Semiotic studies in South Korea have a relatively short history; nevertheless, they enjoy a rapid development from a high starting point, so their research scale and insightful perspectives should not be underestimated. The introduction of “structuralist theory” in the late 1960s paved the way for Korean semiotics to enter the academic arena ideologically and theoretically. In the process of following the international trend of semiotic research, Korean semiotics has also formed its own characteristics. After over 40 years of development, it has become an important part of the world’s semiotic studies. It has experienced three historical stages, namely, the budding period (1974–1983), the steady development period (1984–1993), and the comprehensive advancement period (1994–present). The current Korean semiotics presents obvious new trends as follows: conducting cross-regional integration research, highlighting the national characteristic culture, and focusing on the current application of research. First, Korean scholars switched their focus to East Asia, and emphasized the presentness and application of related research while focusing on the combination of semiotics with traditional cultural classics and cultural heritage. Second, in terms of the field of study, Korean semiotics has expanded across multiple fields such as linguistics, literature, aesthetics, philosophy, communication and traditional culture, music, dance, film, architecture, design, and so forth. Finally, in terms of studying the application of semiotics, it has already reached a considerable scale and depth. Although semiotic research in Korea still needs continuous efforts in enhancing theoretical depth and rigor, it has created a wide development space and displayed unlimited potential in terms of innovation of research perspectives and novelty of ideas.
Controlling chaos in New Keynesian macroeconomics
Authors: Barnett William A. , Bella Giovanni , Ghosh Taniya , Mattana Paolo , Venturi Beatrice 
Published: April 2022

Abstract
In a New Keynesian model, it is believed that combining active monetary policy using a Taylor rule with a passive fiscal rule can achieve local equilibrium determinacy. However, even with such policies, indeterminacy can occur from the emergence of a Shilnikov chaotic attractor in the region of the feasible parameter space. That result, shown by Barnett et al. (2022a), “Shilnikov Chaos, Low Interest Rates, and New Keynesian Macroeconomics,” Journal of Economic Dynamics and Control 134, and again by Barnett et al. (2022b), “Is Policy Causing Chaos in the United Kingdom,” Economic Modeling 108, implies that the presence of the Shilnikov chaotic attractor can cause the economy to drift towards and finally become stuck in the vicinity of lower-than-targeted inflation and nominal interest rates. The result can become the source of a liquidity trap phenomenon. We propose policy options for eliminating or controlling Shilnikov chaotic dynamics to help the economy escape from the liquidity trap or avoid drifting into it in the first place. We consider ways to eliminate or control the chaos by replacing the usual Taylor rule by an alternative policy design without interest rate feedback, such as a Taylor rule with monetary quantity feedback, an active fiscal policy rule with passive monetary rule, or an open loop policy without feedback. We also consider approaches that retain the Taylor rule with interest rate feedback and the associated Shilnikov chaos, while controlling the chaos through a well-known engineering algorithm using a second policy instrument. We find that a second instrument is needed to incorporate a long-run terminal condition missing from the usual myopic Taylor rule.
Data fusion of local and global sensors within a Global Reference System in aeroplane assembly
Authors: Huber Meike , Nicksch Christoph , Schmitt Robert H. 
Published: April 2022

Abstract
Currently, aeroplane assembly is carried out in rigid, aeroplane-specific assembly lines which causes high costs for reconfiguration. One approach to reduce the costs is to use automated lineless assembly systems. To enable automated reconfiguration of assembly processes, continuous availability of factory-wide position data is required. When providing these data, a challenge is the combination of large-volume, “global” measurement sensors and high-precision, “local” measurement sensors to a single easily interpretable indication. The aim of this research work is the fusion of local and global measurement data within a so-called Global Reference System (GRS). For data fusion, sensors are linked to a reference measurement system covering the entire assembly area. The relationships between the coordinate systems of the individual measurement systems are described using homogeneous transformations. Using Kalman filters, the transformed measurement data are fused into a vector containing information about the pose of aeroplane components. Furthermore, a GUM-compliant statement about the measurement uncertainty of the fused sensor data is made by specifying the covariance matrix. The method is validated using a demonstrator covering the essential aspects of the assembly process. The result is a validated procedure for data fusion and for the determination of the combined measurement uncertainty in a GRS.
The Psychometric Properties of the Short Physical Performance Battery to Assess Physical Performance in Older Adults: A Systematic Review
Authors: Kameniar Kate , Mackintosh Shylie , Van Kessel Gisela , Kumar Saravana 
Published: April 2022

Background:
Maintaining physical performance in older age is critical. The Short Physical Performance Battery (SPPB) is one of many tools available to measure physical performance in older people.

Purpose:
Describe the psychometric properties of the SPPB.

Methods:
Using a systematic review methodology, quantitative studies addressing the validity, reliability, and sensitivity of the SPPB in populations 60 years or older were included. We searched 8 databases: MEDLINE, CINAHL, Cochrane, Ageline, Amed, Embase, Scopus, and Emcare, as well as gray literature. Two researchers independently screened, appraised, and extracted data from the literature, following which a descriptive synthesis was undertaken.

Results:
Twenty-eight studies with varying methodological quality were included. Floor and ceiling effects were reported in 4 studies, generally related to very high or very low functioning adults. Nineteen studies investigated validity with varying correlations between the SPPB and other physical performance assessment tools. Ten studies reported good to excellent reliability (intraclass correlation coefficient ranging 0.82-0.92). Minimum detectable change indicates low sensitivity (ranging 0.7-3.42).

Discussion:
Evidence from the literature indicates that the SPPB is a reliable and valid measure of physical performance in adults older than 60 years. However, the SPPB has a narrow scope and is most appropriate for frail older adults who can ambulate and are cognitively able to follow instructions. It has limited applicability for specific populations such as people with dementia who have difficulty following instructions. Targeted training for users may improve its usability and success in clinical practice.

Conclusions:
Clinicians should be mindful that while the SPPB has good validity and reliability, it has limited applicability for people with dementia and is not particularly sensitive to change. In practice, this means that it provides a good snapshot of a client's physical performance compared with the rest of the older population; it is less useful for tracking changes to physical performance over time.
Effects of Differences in Exercise Programs With Regular Resistance Training on Resting Blood Pressure in Hypertensive Adults: A Systematic Review and Meta-Analysis
Authors: Igarashi Yutaka 
Published: April 2022

Abstract
Igarashi, Y. Effects of differences in exercise programs with regular resistance training on resting blood pressure in hypertensive adults: A systematic review and meta-analysis. J Strength Cond Res XX(X): 000–000, 2022—This systematic review and meta-analysis aimed to evaluate changes in resting blood pressure (RBP) with differences in regular resistance training (RT) programs. Inclusion criteria were randomized controlled trials involving hypertensive adults and interventions involving only RT of both the upper and lower limbs for ≥7 weeks. The weighted mean difference (WMD) was defined as the mean difference between the exercise and control groups, weighted by the inverse of the squared standard error for each study, and all WMDs in RBP were pooled as overall effects. A simple meta-regression analysis was performed to evaluate the relationship between RT variables (percentage 1 repetition maximum [1RM], number of repetitions, number of sets, and weekly frequency) and changes in RBP. Seventeen studies (646 subjects) were analyzed. The pooled WMDs in the resting systolic blood pressure (RSBP) and resting diastolic blood pressure (RDBP) decreased significantly but contained significant heterogeneity {RSBP, −4.7 mm Hg (95% confidence interval [CI], −6.7 to −2.8; I
2 = 46.6%); RDBP, −3.5 mm Hg (95% CI, −4.9 to −2.1; I
2 = 39.1%)}. Meta-regression analysis revealed that an increase in % 1RM was significantly associated with a decrease in the RSBP (γ = −0.25x0 + 10.85, where γ represents the mean difference in RSBP, and x0 represents % 1RM [%]), and heterogeneity was alleviated (I
2 = 0.0%). For reducing RSBP, regular RT with moderate or heavy loads may be more beneficial than regular RT with light loads.
