A positive, negative and zero sequences electric power, to improve upon the standard IEEE 1459-2010
Authors: Bialobrzheskyi Oleksii V. , Rod'Kin Dmytro 
Published: July 2022

Purposes
The purpose of this paper is to identify on the instantaneous electrical power basis of a nonsinusoidal periodic current three-phase asymmetric system, active and reactive positive, negative and zero sequence powers, taking into account higher harmonics. The main power theories, including those embodied in the IEEE 1459 standard, do not allow to evaluate some of power components.

Design/methodology/approach
A well-known fact is that the three-phase AC system total power with the symmetry of currents and voltages is constant. It corresponds to the electrical energy transfer process in a DC system. In this case, the electrical energy transmission can be taken as high quality. It has been established that the components of active and reactive powers are because of the product of current and voltage of unidirectional sequences. The orthogonal components of the oscillating power are because of the product of the voltage and current components of different sequences, with the exception of the zero sequence.

Findings
For an unbalanced nonsinusoidal mode of a three-phase system, the components of instantaneous power were defined, corresponding to the active and reactive positive and negative and zero sequences powers with the selection of the fundamental and higher harmonics. The active and reactive powers of sequences were divided into two categories – consumed and generated.

Originality/value
It is proposed to use the ratio of “interfere” power RMS value to the total power RMS value to assess the instantaneous power distortion.
Gender difference in nutrition and health in Nigeria’s agricultural households: the role of corporate social responsibility in oil-producing communities
Authors: Uduji Joseph Ikechukwu , Okolo-Obasi Elda Nduka 
Published: July 2022

Purpose
The purpose of this paper is to critically examine the multinational oil companies’ (MOCs) corporate social responsibility (CSR) initiatives in Nigeria. Its special focus is to investigate the impact of the global memorandum of understanding (GMoU) on gender difference in nutrition and health in the Niger Delta region of Nigeria.

Design/methodology/approach
This paper adopts a survey research technique, aimed at gathering information from a representative sample of the population, as it is essentially cross-sectional, describing and interpreting the current situation. A total of 800 women respondents were sampled across the rural areas of the Niger Delta region.

Findings
The results from the use of a combined propensity score matching and logit model indicate that CSR of the MOCs using GMoU model has made significant success in closing the gender difference in nutrition and health in agricultural household in the Niger Delta region. The findings also show that mainstreaming gender in nutrition within the field of agriculture is a critical aspect of strengthening gender and nutrition/health linkages, in recognition of women’s substantial contribution to agriculture production and their central role in household food collection, preservation/processing and preparation.

Practical implications
This suggests that mainstreaming gender in nutrition offers opportunities to integrate agriculture and health approaches in GMoU projects, which will require increased collaboration and coordination between the MOCs’ and CBD clusters in the field of gender and nutrition to exploit existing complementary and comparative advantages, and to apply a holistic approach in host communities.

Social implications
This implies that gender and nutrition/health have multiple dimensions and are highly context-specific; and the pathway towards improved food and nutrition security for all should be a gender-equitable process incorporated in CSR programmes and projects in sub-Saharan Africa.

Originality/value
This research contributes to the gender debate in agriculture from a CSR perspective in developing countries and rationale for demands for social project by host communities. It concludes that business has an obligation to help in solving problems of public concern.
A deep learning counting model applied to quality control
Authors: Jaramillo Juan R. 
Published: July 2022

Purpose
This paper aims to present two different methods to speed up a test used in the sanitary ware industry that requires to count the number of granules that remains in the commodity after flushing. The test requires that 2,500 granules are added to the lavatory and less than 125 remain.

Design/methodology/approach
The problem is approached using two deep learning computer vision (CV) models. The first model is a Vision Transformers (ViT) classification approach and the second one is a U-Net paired with a connected components algorithm. Both models are trained and evaluated using a proprietary data set of 3,518 labeled images, and performance is compared.

Findings
It was found that both algorithms are able to produce competitive solutions. The U-Net algorithm achieves accuracy levels above 94% and the ViT model reach accuracy levels above 97%. At this time, the U-Net algorithm is being piloted and the ViT pilot is at the planning stage.

Originality/value
To the best of the authors’ knowledge, this is the first approach using CV to solve the granules problem applying ViT. In addition, this work updates the U-Net-Connected components algorithm and compares the results of both algorithms.

Ecological significance of intraplant variation: Epigenetic mosaicism in Lavandula latifolia plants predicts extant and transgenerational variability of fecundity‐related traits
Authors: Herrera Carlos M. , Medrano Mónica , Bazaga Pilar , Alonso Conchita 
Published: July 2022

Abstract

Intraindividual epigenetic mosaicism is probably widespread among long‐lived plants, yet its ecological significance as a potential source of variation in fitness‐related traits in plant populations remains virtually unexplored. This paper examines the hypothesis that extant epigenetic variation within plants can have both current and transgenerational fecundity correlates which could eventually translate into fitness variations among different parts of the same individual and their respective offspring.

Five modules, each consisting of a terminal branchlet bearing one inflorescence and its subtending leaves, were collected from each of 15 wild‐growing Lavandula latifolia (Lamiaceae) plants. They were characterized epigenotypically by the methylation state of methylation‐sensitive amplified fragment length polymorphism (MS‐AFLP) markers, and phenotypically by fecundity‐related traits (inflorescence length, and size, number and mass of seeds produced). Seeds from the different modules were sown in the greenhouse and resulting ‘subprogenies’ characterized phenotypically (germination probability and time to emergence, seedling size, susceptibility to fungal disease).

All plants sampled were internally heterogeneous with regard to the methylation state of 1%–13% of MS‐AFLP markers. Predictable relationships were found between epigenotypic and phenotypic variation across the extant modules of individual L. latifolia shrubs. Phenotypes of subprogenies from different modules of the same plant grown under homogeneous conditions in the greenhouse were predictably related to the epigenotype of the maternal module which produced the seeds.

Synthesis. The variable epigenotypes of different modules in the same plant not only predicted extant phenotypic variation among the modules themselves, but also phenotypic differences among the subprogenies produced by different modules. These relationships linking intraplant epigenotypic mosaicism with both extant and transgenerational heterogeneity in fitness‐related traits support the ‘epigenetic mosaicism hypothesis’ for plant variation, and also suggest hitherto unexplored ecological consequences of epigenotypically enhanced variation in the context of plant populations and communities.

Published: July 2022

AbstractEnhancer of zeste homologue 2 (EZH2) is a clarified promoter in a list of tumours, including osteosarcoma (OS). Our research was projected to define the mechanism involved in EZH2‐mediated OS progression through the protein kinase B (AKT)/glycogen synthase kinase 3β (GSK3β) pathway. EZH2 expression was tested in 66 OS tissues and five osteosarcoma cell lines (143B, SJSA‐1, HOS, MG63, and U2OS). In HOS and U2OS cells, cellular malignant characteristics, and the markers of the AKT/GSK3β signalling pathway were measured when EZH2 was silenced or overexpressed. Meanwhile, rescue assays were implemented to observe whether the AKT/GSK3β signalling pathway inhibitor (MK‐2206) could affect the role of overexpressed EZH2 in OS cells. EZH2 was up‐regulated in tumour tissues of OS patients. OS cell lines (HOS and U2OS) showed impairments of proliferative, migratory, invasive and anti‐apoptotic properties when EZH2 was silenced. Downregulated EZH2 inhibited the activation of the AKT/GSK3 signalling pathway. However, the situation in HOS and U2OS cells over‐expressing EZH2 was opposite. MK‐2206 erased EZH2 up‐regulation‐induced promotion of OS cell growth. It is demonstrated that EZH2 promotes the progression of OS via inducing the activation of the AKT/GSK3β pathway, offering a therapeutic direction for OS treatment.

AbstractThe COVID‐19 pandemic has caused drastic disruptions to many multinational companies’ (MNCs’) supply chain management, pushing them to relocate their manufacturing activities to their home countries, a phenomenon known as reshoring. Grounded in moral psychology theory and the resource‐based view (RBV), the aims of this research are to provide an extended conceptualization of sustainable development goal (SDG) perceptions from local consumers, develop a scale, and assess this scale in relation to the reliability and validity of consumer perception of SDG antecedents and consequences in reshoring contexts from three industries, with the help of six studies. We conceptualise these perceptions on the basis of seven components (i.e. society/community wellbeing, affordable and clean energy consumption, economic growth, responsible consumption, responsible production, sustainable industrialization and innovation and gender equality). Using data from three distinct industries and a sample of 1075 reshoring MNC customers, we also determine how local consumers perceive and react to reshoring initiatives geared towards achieving SDGs and advocacy. The findings offer relevant implications for both the management and research of SDGs in a reshoring context at a scale level, which we describe in the form of future research directions.
Racism towards the Chinese Minority in Malaysia: Political Islam and Institutional Barriers
Authors: Chin James 
Published: July 2022

AbstractPolitics in Malaysia revolves around the tensions between the three major ethnic groups: Malays, Chinese and Indians. After the 1969 ethnic riots, the country adopted an affirmative action programme widely regarded as racist towards the non‐Malays. The rise of political Islam in recent times has added a religious layer to institutional racism. This article looks at contemporary racism towards the Malaysian Chinese community and argues that things will get worse in the future owing to the omnipresence of the Malay Islamic supremacy ideology.
Impact of the Affordable Care Act's Physician Payments Sunshine Act on branded statin prescribing
Authors: Li Jing , Wu Bingxiao , Flory James , Jung Jeah 
Published: July 2022

AbstractObjectiveTo evaluate the impact of the Affordable Care Act's Physician Payments Sunshine Act (PPSA), which mandates disclosure of industry payments to physicians, on physician prescribing of branded statins.Data SourcesAdministrative claims data from 2011 to 2015 from three large national commercial insurers were provided by the Health Care Cost Institute.Study DesignWe adopted a difference‐in‐differences and event study design, leveraging the control group of physicians in two states, MA and VT, which implemented state laws on disclosure of industry payments prior to the national PPSA. To further address potential confounding caused by differences in prescribing patterns across states, our analytical sample includes physicians practicing in border counties between the treatment (NH, NY, and RI) and control (MA and VT) states.Data CollectionWe restricted our sample to physicians who had at least 50 new‐fill prescription claims for statins during the five‐year study period, with at least one new‐fill prescription claim each year.Principal FindingsWe found that the PPSA led to a 7% (p < 0.001) reduction in monthly new prescriptions of brand‐name statin over the study period, with little change in generic prescribing. The reduction in branded prescriptions was concentrated among physicians with the highest tercile of drug spending pre‐PPSA, with a decrease of 15% (p < 0.001) in new branded statin prescriptions. The decline was most prominent after mandated reporting of industry payments began before the payment data was published.ConclusionsThe PPSA may have achieved its intended effect of reducing branded prescriptions at least in the short run, particularly among physicians most likely to have engaged in excessive or low‐value prescribing of branded drugs.

Published: July 2022

AbstractCone‐beam computed tomography (CBCT) enables the assessment of regressive morphological changes in teeth, which can be used to predict chronological age (CA) in adults. As each tooth region is known to have different correlations with CA, this study aimed to segment and quantify the sectional volumes of the tooth crown and root from CBCT scans to test their correlations with the chronological age (CA). Seventy‐five CBCT scans from individuals with age between 20 and 60 years were collected retrospectively from an existing database. A total of 192 intact maxillary anterior teeth fulfilled the eligibility criteria. The upper tooth volume ratio (UTVR), lower tooth volume ratio (LTVR), and sex were used as predictor variables. The UTVR and LTVR parameters were both found to be differently correlated to CA and independent from each other. Regression models were derived from each tooth, with the highest R2 being the maxillary lateral incisor (R2 = 0.67). Additional single predictor models using each ratio were capable of reliably predicting the CA. The segmentation approach in volumetric adult dental age estimation proved to be beneficial in enhancing the reliability of the regression model.

Published: July 2022

AbstractBackgroundThe use of immune checkpoint inhibitors (ICIs) as first‐line treatment rather than as second‐line treatment makes a big difference in the drug efficacy and progression‐free survival. However, the mechanism for this is still not clear. This study aimed to analyze the effects of the rest period between chemotherapy and immunotherapy on the efficacy of ICIs.MethodsThis study included 100 patients with advanced NSCLC treated with PD‐1/PD‐L1 inhibitors at Chungnam National University Hospital (CNUH) between May 2016 and August 2019. The rest period was defined from the last dose of cytotoxic chemotherapy to the first dose of ICIs. We retrospectively reviewed patients' clinical data and blood test records and analyzed lymphocyte subsets using flow cytometry.ResultsThe median rest period was 64 days. The long rest period group (≥36 days) showed significantly higher clinical benefits than the short rest period group (<36 days) (69.4% vs. 39.5%, p = 0.003). White blood cell (WBC) count, absolute neutrophil count (ANC), absolute lymphocyte count (ALC), and neutrophil‐lymphocyte ratio (NLR) just before chemotherapy were not different between the two groups. However, the blood test after chemotherapy immediately before immunotherapy showed significantly higher ANC and NLR in the short rest period group than in the long rest period group. The frequency of the Th1 subset and PD‐1 + CD8+ T cells were significantly higher in the long rest period group than in the short rest period group.ConclusionTime interval from chemotherapy to immunotherapy may affect immune cell status and efficacy of ICIs.

AbstractA variety of intrinsic and extrinsic factors contribute to the altered efficiency of CTLs in elderly organisms. In particular, the efficacy of antiviral CD8+ T cells responses in the elderly has come back into focus since the COVID‐19 pandemic outbreak. However, the exact molecular mechanisms leading to alterations in T cell function and the origin of the observed impairments have not been fully explored. Therefore, we investigated whether intrinsic changes affect the cytotoxic ability of CD8+ T cells in aging. We focused on the different subpopulations and time‐resolved quantification of cytotoxicity during tumor cell elimination. We report a surprising result: Killing kinetics of CD8+ T cells from elderly mice are much faster than those of CD8+ T cells from adult mice. This is true not only in the total CD8+ T cell population but also for their effector (TEM) and central memory (TCM) T cell subpopulations. TIRF experiments reveal that CD8+ T cells from elderly mice possess comparable numbers of fusion events per cell, but significantly increased numbers of cells with granule fusion. Analysis of the cytotoxic granule (CG) content shows significantly increased perforin and granzyme levels and turns CD8+ T cells of elderly mice into very efficient killers. This highlights the importance of distinguishing between cell‐intrinsic alterations and microenvironmental changes in elderly individuals. Our results also stress the importance of analyzing the dynamics of CTL cytotoxicity against cancer cells because, with a simple endpoint lysis analysis, cytotoxic differences could have easily been overlooked.

Published: July 2022

Abstract
Frankliniella occidentalis is a pest of horticultural crops, including commercial strawberry (Fragaria x ananassa). Control is challenging because certain populations are resistant to insecticides and, in strawberry, now relies on the application of biocontrols. However, this approach is not always successful if F. occidentalis populations overwhelm biocontrols. We investigated whether targeted spectral modifications to cladding materials could reduce numbers of F. occidentalis, in strawberry flowers.
Five UV‐attenuating plastic‐film materials were tested in three, 6‐week, semi‐field tunnel experiments containing strawberry plants. F. occidentalis were introduced into tunnels from a laboratory culture and subsequent numbers that developed in strawberry flowers were recorded.
Limiting UV‐A radiation to the crop significantly reduced the numbers of adult and larval F. occidentalis in strawberry flowers. The numbers of adult (and larvae) in flowers were reduced by 42 (47)%, 54 (41)%, 70 (73)%, and 82 (73)% in UV350, UV370, UV400, and UV430‐attenuating films, respectively, compared with the UVopen (control) film. However, no damage to strawberry fruits was observed regardless of the film treatment.
Incorporating UV‐attenuating films as tunnel cladding can suppress F. occidentalis numbers in strawberry. Reducing populations of F. occidentalis in crops is likely to enable the more successful use of other non‐chemical control strategies.

Published: July 2022

AbstractBackgroundChest wall sarcomas are a rare group of tumours. Surgical resection is considered the mainstay of curative treatment, however, resection and reconstruction of chest wall defects presents complex issues for the clinician.MethodsA retrospective analysis of 59 patients undergoing surgical management of chest wall sarcoma between December 1996 and July 2020 was conducted across a multidisciplinary sarcoma service in Melbourne, Australia. Patient demographics, pathologic data, and long‐term outcomes were recorded.ResultsMean age at surgery was 48.4 years (SD 18.3), and 66.1% were male. Median follow‐up was 29 months (IQR 11.8, 51.0 months). Fifty‐one patients presented with primary tumours, while the others had secondary tumours resected. Most tumours arose in bone (72.9%) as opposed to soft tissues (27.1%). Chondrosarcoma was the most common histologic subtype (50.8%). The most common reconstructive techniques involved the use of mesh (79.7%) or mesh supplemented with bone cement (33.9%). Overall survival at 1 and 5 years was 92% and 70%, respectively. Seven patients died of metastatic sarcoma during the follow up period with a median survival time of 27 months. Twelve patients had evidence of disease recurrence during the follow‐up period. Stage 4 disease, soft tissue tumours, secondary tumours, leiomyosarcoma and UPS subtypes, and plating reconstruction were associated with increased disease recurrence.ConclusionsThe results suggest that outcomes for chest wall sarcoma are similar to extremity sarcomas and may be treated in a similar manner. Patients requiring adjuvant radiotherapy and those who develop disease‐recurrence are more likely to have worse overall survival outcome despite complete surgical resection.
