Non-invasive calibration of a Stewart platform by photogrammetry
Authors: Karmakar Sourabh , Turner Cameron J. 
Published: April 2024

AbstractAccurate calibration of a Stewart platform is important for their precise and efficient operation. However, the calibration of these platforms using forward kinematics is a challenge for researchers because forward kinematics normally generates multiple feasible and unfeasible solutions for any pose of the moving platform. The complex kinematic relations among the six actuator paths connecting the fixed base to the moving platform further compound the difficulty in establishing a straightforward and efficient calibration method. The authors developed a new forward kinematics-based calibration method using Denavit-Hartenberg (DH) convention and used the Stewart platform “Tiger 66.1” developed in their lab for experimenting with the photogrammetry-based calibration strategies described in this paper. This system became operational upon completion of construction, marking its inaugural use. The authors used their calibration model for estimating the errors in the system and adopted three compensation options or strategies as per least-square method to improve the accuracy of the system. These strategies leveraged a high-resolution digital camera and off-the-shelf software to capture the poses of the moving platform’s center. This process is non-invasive and does not need any additional equipment to be attached to the hexapod or any alteration of the hexapod hardware. This photogrammetry-based calibration process involves multiple high-resolution images from different angles to measure the position and orientation of the platform center in the three-dimensional space. The target poses and actual poses are then compared, and the error compensations are estimated using the least-square methods to calculate the predicted poses. Results from each of the three compensation approaches demonstrated noticeable enhancements in platform pose accuracies, suggesting room for further improvements. Given that “Tiger 66.1” is based on the general Stewart platform structure, the proposed calibration method holds promise for extension to machines operating on similar principles where non-invasive calibration is desirable. This study contributes to advancing the field of Stewart platform calibration, paving the way for more precise and efficient applications in various domains.
Stability conditions and Teichmüller space
Authors: Allegretti Dylan G. L. 
Published: April 2024

AbstractWe consider a 3-Calabi–Yau triangulated category associated to an ideal triangulation of a marked bordered surface. Using the theory of harmonic maps between Riemann surfaces, we construct a natural map from a component of the space of Bridgeland stability conditions on this category to the enhanced Teichmüller space of the surface. We describe a relationship between the central charges of objects in the category and shear coordinates on the Teichmüller space.

Abstract
Purpose
The aim of this registry was to assess technical success, procedural safety and mid- to long-term follow-up results of the Silk Vista “Mama” (SVM) flow diverter (BALT, Montmorency, France) for the treatment of proximal intracranial aneurysms.

Methods
Between August 2020 and March 2022, data from nine Italian neurovascular centres were collected. Data included patients’ clinical presentation, aneurysms’ size, location and status, technical details, overall complications and mid- to long-term angiographic follow-up.

Results
Forty-eight aneurysms in 48 patients were treated using the SVM. Most aneurysms were small (≤ 10 mm: no. 29, 60%) and unruptured (no. 31, 65%); 13 aneurysms were recurrent after coiling or clipping. 37/48 aneurysms involved the internal carotid artery (77%). Optimal opening and complete wall apposition of the device were achieved in 46 out of 48 cases (96%). Four intra- or periprocedural complications occurred (two thrombotic complications successfully resolved, one cerebellar ischemia, one perirenal hematoma), without new neurological deficit. No significant intra-stent stenosis or stent displacement was observed during follow-up. No FD-related morbidity nor mortality was reported. At midterm (6–12 months) to long-term (> 12 months) follow-up, complete aneurysm occlusion (OKM D) was achieved in 76% of cases. Eighty-eight percent of patients had complete aneurysm occlusion or entry remnant (OKM D + C).

Conclusions
Our experience suggests that the new generation of low-profile SVM flow diverter for the treatment of proximal intracranial aneurysms is safe and effective, with low rates of intraprocedural complications and acceptable mid- to long-term occlusion rate.

Published: April 2024

AbstractInitial experiences with magnetic resonance imaging (MRI) of living strangulation victims demonstrated additional findings of internal injuries compared to the standard clinical forensic examination. However, existing studies on the use of MRI for this purpose mostly focused on the first 48 h after the incident. The aims of this study were (a) to evaluate the longitudinal visibility of MRI findings after violence against the neck by performing two MRI examinations within 12 days and a minimum of four days between both MRI scans and (b) to assess which MRI sequences were most helpful for the detection of injuries. Twenty strangulation victims participated in this study and underwent one (n = 8) or two (n = 12) MRI scans. The first MRI examination was conducted during the first five days, the second five to 12 days after the incident. Two blinded radiologists assessed the MRI data and looked for lesions in the structures of the neck. In total, 140 findings were reported in the 32 MRI examinations. Most of the findings were detected in the thyroid and the muscles of the neck. T2-weighted SPACE with fat suppression, T1-weighted TSE and T1-weighted MPRAGE were rated as the most helpful MRI sequences. Subjects who showed findings in the initial scan also demonstrated comparable results in the second scan, which was performed on average 8.4 days after the incident. Our results show that even up to 12 days after the incident, the criminal proceeding of strangulation cases may greatly profit from the information provided by an MRI examination of the neck in addition to the standard clinical forensic examination.

Published: April 2024

Abstract
Purpose
To assess Black women’s exposure to and appraisal of racism-related stress during the postpartum period and to distinguish its impact on three indicators of postpartum mood and anxiety disorders (PMADs) symptoms.

Methods
Data from the Black Mothers’ Mental Wellness Study (N = 231) and linear regression models estimated the associations between racism-related stress and the PMAD indicators: 3-item Edinburgh Postnatal Depression Scale (EPDS-3), 8-item Patient Health Questionnaire (PHQ-8), and PHQ-15.

Results
The majority of participants (80.5%, N = 186) experienced racism a few times a year or more, of which 37.1% (N = 69) were bothered somewhat and 19.3% (N = 36) a lot. Racism-related stress, income, level of education, and history of mental health diagnosis explained greater variance in PMAD symptoms as measured by the PHQ-8 score (R2 = 0.58, p =  < 0.001) compared to the EPDS-3 (R2 = 0.46, p =  < 0.001) or the PHQ-15 (R2 = 0.14, p = 0.035).

Conclusions
Racism is a stressor for Black women living in Los Angeles County, California. Racism-related stress and emotional expression of PMAD symptoms were salient to the postpartum mental health of the Black women in this study. Findings from this study suggest that the PHQ-8 should be used to assess how racism impacts Black women’s postpartum mental health.

Authors: Ferreira Patrícia S. , Ribeiro Sónia M. , Pontes Rita , Nunes João 
Published: April 2024

AbstractBioplastics appear as an alternative to fossil fuel-derived plastics because bioplastics are carbon neutral and often biodegradable, thus potentially solving the issues of plastic pollution and climate change. In particular, polylactic acid is a substitute for traditional petrochemical-based polymers. Here, we review polylactic acid production with focus on surface modification and integration of bioactive compounds. Surface can be modified by chemical treatment, photografting, surface entrapment, plasma treatment, and coating. Bioactive compounds can be incorporated by encapsulation, impregnation, melt blending, solvent casting, electrospinning, and in situ polymerization. Biomedical and packaging applications are discussed.

Published: April 2024

AbstractIn this paper, we propose a three-way decision (TWD) method on multi-scale single-valued neutrosophic decision systems (MS-SVNDSs). First, to explore the application of single-valued neutrosophic sets (SVNSs) in multi-scale environment, we establish a rough set model of MS-SVNDSs. Then, aiming at the problem of knowledge acquisition in MS-SVNDSs, we present the corresponding optimal scale selection and reduction methods by using evidence theory, a more direct and simpler algorithm is also discussed. For obtaining decision results that are more in line with human cognition, we further provide a novel three-way decision method. Comparative experiments are subsequently conducted to demonstrate the effectiveness of our approach. The experimental results show that our method not only improves the classification accuracy but also raises decision efficiency.
Country Differences in the Effects of Individual Traits on Depression in Women in Europe

Published: April 2024

AbstractMental health and, in particular, depression are of great global concern today, especially in middle- and high-income countries. These health issues show an unequal gender prevalence as they are more common in women than in men. The aim of this work is to use micro-econometric models to analyze the prevalence of depression in women in 27 European countries, as well as to quantify the effects of certain individual characteristics on the probability of experiencing depression and the degree to which it occurs. In addition, measures are proposed to assess how each country differs from the total sample. The data used proceed from the European Health Interview Survey wave 2 (EHIS-2). The results show that higher educational levels and incomes are protective factors, while older age and being unemployed have a positive effect on the probability of having depression, particularly on the probability of severe depression. Furthermore, from the calculation of ratios, notable differences are detected in the effects of these characteristics in different countries. Although the direction of the effect of each characteristic is similar in all countries, the size of the effect in each country varies significantly from the sample average. The results highlight the importance of identifying which individual traits generate a higher propensity to experience depression in women. The proposed procedure leads to the conclusion that the detection of differences and similarities between countries could allow the extrapolation of successful practices in prevention and mental health care.
Outcomes in Cirrhosis-Related Refractory Ascites with Emphasis on Palliative Care: Single-Centre Experience and Literature Review
Authors: English Marcus Rex , Ellis Jordache , Verma Sumita , Haddadin Yazan 
Published: April 2024

Abstract
Purpose of Review
Despite refractory ascites (RA) due to cirrhosis having a median transplant-free survival of 6–12 months, palliative care (PC) input remains uncertain. We aimed to review the existing literature on clinical outcomes in cirrhosis-related RA and report the findings of a single-centre retrospective cohort study with a special focus on linkage to PC in this cohort of patients.

Recent Findings
Our study and subsequent literature review confirm the high mortality associated with cirrhosis-related RA (19–55% 1-year mortality) with only a minority of patients receiving curative options (3–23%). Despite this, in our study only a minority of patients (33%) were referred to PC. None of the studies identified in the scoping review makes any references to palliative care use.

Summary
Our own data and a literature review confirm that, despite high mortality, only a minority with RA due to cirrhosis are referred for specialist PC input and often too late in their disease trajectory. Future research should focus on patient-centred outcomes in this cohort of patients where optimising quality-of-life and facilitating advanced care planning should be a priority.
Mikrofluidische Partikelgrößenbestimmung
Authors: Bauernhofer Lena , Glueck David , Krainer Georg , Keller Sandro 
Published: April 2024

AbstractMicrofluidic diffusional sizing (MDS) is a powerful lab-on-a-chip method for determining the particle sizes, interactions, and association states of fluorescent analytes. MDS requires only microliter volumes and works even in heterogeneous, unpurified samples. Here we describe how MDS can be used to study (i) antibody binding and cellular copy numbers of oncoproteins, (ii) charge-dependent interactions of proteins with lipid membranes, and (iii) the size of native nanodiscs. We also show how single-molecule MDS (smMDS) achieves ultimate sensitivity and superior size resolution through digital counting.

Published: April 2024

AbstractIn in vitro fertilization, the status of the zona pellucida is of pivotal interest to determine the window of best fertilization. In this window, the zona pellucida becomes soft, so that a sperm can penetrate. Two lab-on-chip systems will be introduced which were developed to monitor the status of the zona pellucida of mouse oocytes with electrical impedance spectroscopy. The combination of microfluidic systems and impedance spectroscopy offer advantages of easy cell handling and observer-independent characterization.
Unerwartete räumlich-zeitliche Muster des bakteriellen Membranpotenzials
Authors: Hennes Marc , Maier Berenike 
Published: April 2024

AbstractBacteria maintain electrical polarization across their membrane, which is crucial for ATP synthesis, membrane transport, and other cellular functions. Recent studies showed astonishing polarization dynamics governed by electrical and mechanical stimuli, as well as antibiotic treatment. These dynamics affect bacterial survival in a complex way. While cell-to-cell heterogeneity is prominent, several studies report collective polarisation patterns in response to limitation of growth resources.
Kleb‘s zusammen & zerleg‘s: Detergensproteine in der zelleigenen Immunität
Authors: Kutsch Miriam 
Published: April 2024

AbstractThe spread of antibiotic resistances among bacteria led to an increase in multidrug resistant pathogens. New therapies are urgently needed to tackle the current global antibiotic crisis. One strategy is to boost the ancient antimicrobial defense conserved in all vertebrates: the innate immune system. To develop such therapies, a fundamental understanding of host-pathogen interactions is crucial. We study how detergent-like host factors combat bacterial pathogens in cell-autonomous immunity.
Sexual Orientation and Gender Identity Among Donor-Conceived Offspring in the U.S. National Longitudinal Lesbian Family Study from Adolescence to Adulthood
Authors: Carone Nicola , Rothblum Esther D. , Koh Audrey S. , Bos Henny M. W. , Gartrell Nanette K. 
Published: April 2024

Abstract
Introduction
Concerns about parents with minoritized sexual identities often focus on the belief that their children will be confused about their gender and report a non-heterosexual orientation compared to children reared by heterosexual parents. Yet, few longitudinal studies exist.

Methods
Gender identity, gender expression, sexual orientation, and sexual experiences were examined in 75 U.S. donor-conceived offspring (39 assigned females at birth (AFAB) and 36 assigned males at birth (AMAB)) of lesbian parents, when the offspring had reached adulthood (ages 30–33). Additionally, 72 of these offspring (38 AFAB and 34 AMAB) had also completed surveys in adolescence (age 17, data collected 2004–2009) and emerging adulthood (age 25, data collected 2012–2017), which enabled us to examine the developmental pathways of their sexuality.

Results
All AMAB offspring and 94.7% of AFAB offspring who identified as cisgender during adolescence continued to do so during emerging adulthood and adulthood. Over time, sexual orientation was more fluid than gender identity, and AFAB offspring were more fluid than AMAB offspring. Specifically, considering those who reported the same (heterosexual/straight; lesbian, gay/homosexual; or bisexual+) sexual orientation from adolescence through emerging adulthood to adulthood, 63.9% were AFAB and 82.4% were AMAB. More than half of AFAB offspring and 80.6% of AMAB offspring identified as heterosexual in adulthood, and the vast majority had had sex with a non-transgender man (86.5%) and a non-transgender woman (93.6%), respectively, in the last 5 years.

Conclusions
This is the only study that has followed the biological offspring of lesbian parents from birth to adulthood, prospectively and longitudinally. The results indicate that offspring of lesbian parents are less likely to identify as transgender than the general public, but more likely to identify as LGB or queer.

Policy Implications
As gender and sexual identity development significantly impacts well-being, creating supportive environments for offspring of lesbian parents and increasing public awareness of the connections among developmental milestones, health, and thriving are vital.
Emerging techniques for the processing of food to ensure higher food safety with enhanced food quality: a review
Authors: Jadhav Harsh B. , Choudhary Pintu 
Published: April 2024

AbstractIn recent years the consumer’s preference for highly convenient food possessing superior characteristics, high nutritional value with minimum processing, easy to eat, safe, should have a longer shelf life and mouth-watering taste has increased. All these demands of the consumer are impossible to be fulfilled by the existing thermal treatments, which provide food with reduced nutritional and sensory qualities with lesser shelf life. This diverted the attention of food professionals towards non-thermal technologies which are eco-friendly, energy-efficient, and do not process food at a higher temperature for a longer time. As a result, non-thermal technology delivers food with higher nutritional and sensory values and with longer shelf life. Non-thermal treatments are cost-effective technologies that constitute a newer bunch of tools that are developing steadily and are being explored across the globe. This review discusses in brief non-thermal technologies like ultraviolet, pulse electric field, high-pressure processing, ultrasonication, cold plasma, and supercritical carbon dioxide.

Abstract
In this paper, we consider the nonlinear Schrödinger’s equation with Kudryashov’s law of refractive index. By using the method of dynamical systems, we obtain bifurcations of the phase portraits of the traveling wave system under different parameter conditions. Corresponding to some special level curves, we derive possible exact explicit parametric representations of solutions (including peakon, periodic peakon, solitary wave solutions and compactons) under different parameter conditions.
Restoring Dialogical Rule of Law in the European Union: Janus in the Mirror
Authors: Kochenov Dimitry V. 
Published: April 2024

Abstract
The primacy of EU law as framed by the Court of Justice pre-empts substantive arguments of principle that originate in other legal orders. This was accepted and acceptable to the extent that the values EU law contained were at least normatively equivalent to values originated from the other legal orders. In this contribution it is argued that this is no longer the case and that the misuse of the Rule of Law rhetoric justifying the primacy of EU law renders the EU less accountable and undermines the dialogical pluralist essence of EU constitutionalism.

Published: April 2024

Abstract

Objective:
This research was conducted in order to assess the 1-week aid needs determined by the health professional who voluntarily served in the WhatsApp communication network during the earthquakes in Kahramanmaraş, Turkey.

Methods:
This descriptive retrospective epidemiological study focuses on the 1-week messaging activities of the WhatsApp group created by volunteers after the earthquake in Turkey. During the 7-day period included in the research, a total of 5813 messages were sent. 3472 of these messages were not included in the research for various reasons, and a total of 2341 messages were used for the research.

Results:
In all 7 days, it was seen that most of the messages were sent via text message and that voice messages were very few. When the distribution of the needs demanded by the earthquake victims for 7 days was examined, it was seen that there was a significant increase in the needs on the fourth day after the earthquake, and that the highest increase was the need for tents.

Conclusion:
While the demands for rescue services increased in the first 2 days, it was determined that the demands for water especially, dry food, and tents increased from the third day onwards. It is suggested that a professional online infrastructure system should be created to enable the transfer of instant scene and need information that can be activated in such disasters.
