Dynamic Kinematic Primitives Track Planning for Fabrics Palletizing
Authors: zhu Lihong , Zhao LiangCheng , Tan Jiamin , Zhang Dong , Cui Can 
Published: December 2023

Abstract

In the garment industry's fabrics palletizing process, this study confronts significant challenges: increasing diversity of fabric types and changes in palletizing trajectories due to frequent fabric changes. To address these challenges, we introduce a method based on dynamic kinematic primitives for optimizing robot fabric placement trajectory planning. We first establish the basic system equations for the dynamic motion primitives. Considering the necessity of suppressing acceleration variation at the beginning of trajectory, we introduce progressive activation coefficient factor. This factor makes the initial motion smoother and effectively solves the problem of sudden changes in acceleration at the initial position. Additionally, we introduce a new parameter, the rectangular length of the outer contour of the fabric cutting denoted as ' L' into the system equations. This parameter enables autonomous learning and adaptation within the robot, allowing it to manifest distinct motion characteristics tailored to the specific fabric type. The robot can autonomously generate a variety of motion trajectories while retaining core motion characteristics. The validity of our method is verified by varying length L and performing a drag-and-drop demonstration of the robot, deriving the robot's autonomous placement and spreading trajectories. Palletizing experiments were conducted on different types of fabrics. The outcomes confirm the enhanced performance of the dynamic motion primitive method, as it consistently generates fabrics palletizing trajectories harmonized with demonstrated trajectories across varied the fabric types. This study demonstrates the role of dynamic motion primitives in optimizing fabric palletizing to improve productivity in the apparel industry.
Taxing Digital Platforms: A Race to the Top?
Authors: Innocenti Federico , Bucciol Alessandro 
Published: December 2023

Abstract
The digital advertising tax is an increasingly used policy measure, but its consequences must still be better understood. We develop a theoretical model inspired by a recently introduced digital advertising tax in Maryland. While the tax may increase state-level tax revenues, we highlight an unexplored drawback of this policy. The unilateral ability of a country to tax advertising revenues generated in its territories leads to inefficiently high equilibrium tax rates. Our findings emphasize the need for a global initiative on digital platform taxation rather than leaving the decision to individual countries.

Bond-graph Representation of Ideal Constraints Via the Principle of Virtual Power
Authors: Phillips James R. , Amirouche Farid 
Published: December 2023

Abstract

In this paper we develop bond-graph representations for ideal mechanical constraints, both embedded andadjoined, by stating and applying the principle of virtual power, at the particle level, to both types of constraints.The resulting system-level bond graph provides a bond-graphic derivation of Kane's equations for a general nonlinearnonholonomic system. Four examples are then shown to illustrate the application of the method to specific systems. Inthe final example we show how to apply the method to an existing bond graph having causal conflicts that force inertialelements into differential causality. The power and simplicity of the method, when applied in this fashion, recommendit for incorporation into standard procedures for sequential causality assignment of bond graphs.
Development of Neighborhood Trajectories employing Historic Redlining and the Area Deprivation Index

Published: December 2023

Abstract

The role of historic residential redlining on health disparities is intertwined with policy changes made before and after the 1930s that influence current neighborhood characteristics and shape ongoing structural racism in the United States. We developed Neighborhood Trajectories which combine historic redlining data and the current neighborhood socioeconomic characteristics as a novel approach to studying structural racism. Home Owners Loan Corporation (HOLC) neighborhoods for the entire U.S. were used to map the HOLC grades to the 2020 U.S. Census block group polygons based on the percentage of HOLC areas in each block group. Each block group was also assigned an Area Deprivation Index (ADI) from the Neighborhood Atlas®. To evaluate changes in neighborhoods from historic HOLC grades to present degree of deprivation, we aggregated block groups into “Neighborhood Trajectories” using historic HOLC grades and current ADI. The Neighborhood Trajectories are “Advantage Stable”; “Advantage Reduced”; “Disadvantage Reduced”; and “Disadvantage Stable.” Neighborhood Trajectories were established for 13.3% (32,152) of the block groups in the U.S., encompassing 38,005,799 people. Overall, the Disadvantage-Reduced trajectory had the largest population (16,307,217 people). However, the largest percentage of Non-Hispanic/Latino Black residents (34%) fell in the Advantage-Reduced trajectory, while the largest percentage of Non-Hispanic/Latino White residents (60%) fell in the Advantage-Stable trajectory. The development of the Neighborhood Trajectories affords a more nuanced mechanism to investigate dynamic processes from historic policy, socioeconomic development, and ongoing marginalization. This adaptable methodology may enable investigation of ongoing sociopolitical processes including gentrification of neighborhoods (Disadvantage-Reduced trajectory) and “White flight” (Advantage Reduced trajectory).
Polar metabolomics using trichloroacetic acid extraction and porous graphitic carbon stationary phase.
Authors: Day Francesca , O'Sullivan Justin , Ramzan Farha , Pook Chris 
Published: December 2023

Abstract

Accurately identifying and quantifying polar metabolites using untargeted metabolomics has proven challenging in comparison to mid to non-polar metabolites. Hydrophilic interaction chromatography and gas chromatography-mass spectrometry are predominantly used to target polar metabolites. However, the scope of these methods are limited and the extraction and post-analyses can be laborious. Using serum from 6 healthy individuals we demonstrate a simple one step MilliQ + 10% trichloroacetic acid (TCA) extraction combined with porous graphitic carbon liquid chromatography – mass spectrometry (LC-MS) that can reliably retain (Coefficient of variation [CV] <0.30) a range of polar metabolites with logp as low as -9.1 (Range:-9.1-5.6). The use of QreSSTM (Quantification, Retention, and System Suitability) internal standards determined this method consistently (CV<0.16), and effectively (70-130% recovery) recovers polar to mid-polar metabolites within biologically relevant concentration ranges. Quality control dilution series demonstrated ~80% of annotated metabolites can be accurately (Pearsons’s correlation coefficient >0.80) quantified within their concentration range. Repeatability of this method was demonstrated through clustering of repeated extractions from a single sample. This LC-MS method is better suited to covering the polar segment of the metabolome than current methods.
Development and Validation of Group Intervention Module for Women Survivors of Intimate Partner Violence
Authors: Sinu  , Chinnadurai  
Published: December 2023

Abstract

Background: Group work intervention is highly effective for survivors of IPV. There are fewer interventions available in addiction services and intimate partner violence in the Indian context. This study aims to develop and validate the group work module for women survivors of IPV. A standard group work module would help the group workers help the survivors reduce or prevent violence and improve their quality of life.
Methods: The group intervention manual was developed through psychosocial need assessments for intimate partner violence, subject experts' opinions, and expert validation through the content validation index and kappa value. The components of the group intervention manual were developed for women survivors of IPV who are staying with perpetrator inpatient services in the Centre for Addiction Medicine.
Results: The final components included sharing about the experience of intimate partner violence, understanding and impact of IPV, psychoeducation regarding alcohol dependence syndrome and treatment process, importing the social skills, safety plans, and self-care of the survivors and their children, crisis intervention, and resource mapping. The delivery of the group intervention module was refined based on pilot testing with ten participants.
Conclusion: The tailored group work intervention module was designed to be delivered by a research scholar. The group, each session of 40 min to 45 min in every day, consisted of 6 sessions; after the group intervention, feedback was collected from each session.

Abstract

Wastewater surveillance is an effective tool for monitoring community spread of covid-19 and other diseases. Quantitative PCR (qPCR) analysis for wastewater surveillance is more susceptible than binary PCR analysis for clinical surveillance to mutations in target genome regions. The SARS-CoV-2 concentrations in wastewater estimated by N1 and N2 qPCR assays started to diverge around July 2022 in data from different sampling sites, analytical methods, and analytical laboratories in Japan. On the basis of clinical genomic surveillance data and experimental data, we demonstrate that the divergence is due to two mutations in the N1 probe region, which can cause underestimation of viral concentrations. We further show that this inaccuracy can be alleviated if the qPCR data are analyzed with the second derivative method or the Cy0 method instead of the crossing point method.
What does data literacy means for you (as an educator)nowadays?
Authors: Raffaghelli Juliana Elisa , Ferrarelli Mariana , Kühn Caroline 
Published: December 2023

Despite progress in data literacy frameworks associated with a critical discussion of datafication, educators are still perplexed when it comes to working with these issues in their everyday teaching practice. In part, this is due to the complexity of the data infrastructures that permeate educational practice itself. In this context, it seems particularly appropriate to understand the discursive phenomena, the construction of professional practise and therefore the educators’ positionings around the issues of datafication in general, and the development of critical data literacy, namely, “postdigital positinings”.
This paper proposes a collaborative autoethnographic analysis of the professional experiences of the three authors, as educators.
As women with complex migrant identities, with roots in the Global South and at the same time, bearers of European métisages, our pathways meet at the crossover of an international project in which we develop materials and design educational activities. Our history lies on an intersectional basis that allows us to express rich positionalities, full of examples and resources that can be resounding notes for the construction of agentic educational practices in this field of post-digital forces.
A holistic assessment of groundwater quality for drinking and irrigation purposes
Authors: Raheja Hemant , Goel Arun , Pal Mahesh 
Published: December 2023

Abstract
This study discusses about suitability of groundwater for drinking and irrigation use in Rohtak district of Haryana (India). The entropy water quality index (EWQI), sodium absorption ratio (SAR), permeability index (PI), Sodium percentage (Na%), Kelly ratio (KR), magnesium adsorption ratio (MAR), US salinity, and Gibbs diagram were analyzed. The spatial maps suggest that groundwater quality in central part extending towards southwestern part of area can be categorized as poor. The major ions were reported in the following order: Mg2+ &gt; Ca2+ &gt; Na+ &gt; K+, and Cl− &gt; SO42− &gt; NO3− &gt; HCO3− &gt; F− &gt; CO32− respectively. Moreover, results revealed that most of groundwater exceeded desirable limits for drinking water. The EWQI assessment indicates that 23.4% and 38.4% of groundwater samples have extremely poor quality in pre-monsoon and post-monsoon, respectively. Further other indices shows that various indices exceed their standard limit, and mostly samples are unsuitable for irrigation. The Gibbs diagram and other bivariate plots demonstrate that various ions in groundwater can be attributed to silicate and carbonate weathering, which occur through water -rock interactions and ion exchange phenomena. In addition, the US Salinity diagram verifies that most groundwater samples exhibit significant salinity hazards, particularly concerning high sodium levels.
Tailored Prompting to Improve Adherence to Image-Based Dietary Assessment: Mixed Methods Study
Authors: Lee Lachlan , Hall Rosemary , Stanley James , Krebs Jeremy 
Published: December 2023

Abstract

Background
Accurately assessing an individual’s diet is vital in the management of personal nutrition and in the study of the effect of diet on health. Despite its importance, the tools available for dietary assessment remain either too imprecise, expensive, or burdensome for clinical or research use. Image-based methods offer a potential new tool to improve the reliability and accessibility of dietary assessment. Though promising, image-based methods are sensitive to adherence, as images cannot be captured from meals that have already been consumed. Adherence to image-based methods may be improved with appropriately timed prompting via text message.

Objective
This study aimed to quantitatively examine the effect of prompt timing on adherence to an image-based dietary record and qualitatively explore the participant experience of dietary assessment in order to inform the design of a novel image-based dietary assessment tool.

Methods
This study used a randomized crossover design to examine the intraindividual effect of 3 prompt settings on the number of images captured in an image-based dietary record. The prompt settings were control, where no prompts were sent; standard, where prompts were sent at 7:15 AM, 11:15 AM, and 5:15 PM for every participant; and tailored, where prompt timing was tailored to habitual meal times for each participant. Participants completed a text-based dietary record at baseline to determine the timing of tailored prompts. Participants were randomized to 1 of 6 study sequences, each with a unique order of the 3 prompt settings, with each 3-day image-based dietary record separated by a washout period of at least 7 days. The qualitative component comprised semistructured interviews and questionnaires exploring the experience of dietary assessment.

Results
A total of 37 people were recruited, and 30 participants (11 male, 19 female; mean age 30, SD 10.8 years), completed all image-based dietary records. The image rate increased by 0.83 images per day in the standard setting compared to control (P=.23) and increased by 1.78 images per day in the tailored setting compared to control (P≤.001). We found that 13/21 (62%) of participants preferred to use the image-based dietary record versus the text-based dietary record but reported method-specific challenges with each method, particularly the inability to record via an image after a meal had been consumed.

Conclusions
Tailored prompting improves adherence to image-based dietary assessment. Future image-based dietary assessment tools should use tailored prompting and offer both image-based and written input options to improve record completeness.

Authors: Melnychuk I.O. , Sharayeva M.L. , Kramarova V.N. , Lyzogub V.H. 
Published: December 2023

Background. The aim of our work was to identify the links between platelet amino acid (AA) spectrum and gut microbiota composition in patients with coronary artery disease (CAD) and atrial fibrillation (AF) and to evaluate them. Materials and methods. Three hundred patients were enrolled in the study. They were divided into 3 groups: I (CAD) — 149 patients with CAD but without arrhythmias, II (CAD + AF) — 124 people with CAD and AF paroxysm, and control group (CG) — 27 individuals without CAD and arrhythmias. Platelet AA level was assessed by method of ion-exchange liquid column chromatography. Gut microbiota composition was studied by 16-S rRNA sequencing. Results. A significant increase in isoleucine (10.73 %), leucine (12.63 %) and a decrease in threonine (23.05 %), serine (5.06 %), glycine (32.21 %) and valine (30.83 %) platelets levels was found in patients with CAD and AF (P < 0.05). In addition, they had a significant increase in Bacteroides spp., Faecalibacterium prausnitzii, Actinobacter spp., Streptococcus spp., Ruminococcus spp. and a decrease in Lactobacillus spp., Bifidobacterium spp., Eubacterium rectale (P < 0.05). Platelet glutamine acid, valine, glycine, asparagine acid, threonine had the highest number of significant correlations with gut microbiota species (P < 0.05). Actinobacter spp., Blautia spp., Streptococcus spp., Akkermansia muciniphila and Roseburia inulinivorans had the highest number of significant correlations with platelet amino acids (P < 0.05). Conclusions. Platelet amino acid spectrum and gut microbiota composition in patients with coronary artery disease and atrial fibrillation are closely linked.

Authors: Firmando Harisan Boni , Simbolon Elvri Teresia , Lumbantobing Roida 
Published: December 2023

Religion, culture, and politics form a unified entity in society that cannot be separated. These three elements shape human life both socially and as citizens. The purpose of this study was to explore the relationship between religion, culture, and politics within the Toba Batak community in Samosir Regency. This research utilized qualitative methods to comprehensively understand the experiences of the subjects. The findings reveal that the relationship between religion, culture, and politics is evident in the implementation of the 'dalihan na tolu' kinship system. The Toba Batak community exhibits openness towards others outside their tribe, a practice facilitated by incorporating clan affiliations as a basis for determining kinship. The culture of solidarity in the Batak Toba community influences their political behavior. The community supports their family members who run in general elections, with this solidarity serving as both social and economic capital for the Toba Batak people engaging in political activities, particularly for those aspiring to become regional head candidates or council members. In selecting leaders, the Batak Toba community considers not only the educational and other qualifications of potential leaders but also their sociological background.
AbstrakAgama, kebudayaan, dan politik merupakan satu kesatuan di dalam masyarakat yang tidak dapat dipisahkan. Ketiga hal tersebut menyebabkan kehidupan manusia sebagai makhluk sosial dan sebagai warga negara berlangsung. Kajian ini bertujuan untuk mengetahui relasi agama, kebudayaan dan politik pada masyarakat Batak Toba di Kabupaten Samosir. Kajian ini menggunakan metode kualitatif untuk memahami. Hasil Kajian ini menunjukkan relasi agama, kebudayaan dan politik terlihat dalam implementasi sistem kekerabatan dalihan na tolu. Masyarakat Batak Toba dengan orang lain di luar suku Batak Toba, keterbukaan tersebut dilakukan dengan penabalan marga sebagai dasar suku Batak Toba untuk menentukan sistem kekerabatan. Budaya solidaritas menjadi pedoman masyarakat Batak Toba dalam berperilaku politik. Masyarakat akan membantu keluarganya yang maju dalam pemilihan umum. Solidaritas ini merupakan modal sosial sekaligus modal ekonomi bagi masyarakat Batak Toba yang melakukan aktivitas politik, khususnya anggota masyarakat yang maju menjadi calon kepala daerah dan anggota dewan. Pemilihan pemimpin pada masyarakat Batak Toba hingga kini masih memperhitungkan latar belakang calon seorang pemimpin. Latar belakang bukan hanya dari pendidikan atau modal lain dari calon pemimpin yang mumpuni, namun lebih kepada aspek-aspek sosiologis.
