Authors: Odeck James , Presterud Eirik Lund 
Published: July 2023

Abstract

This paper assesses how transforming a cordon toll ring with flat toll rates to a congestion charging scheme works in achieving its intended objectives. The contribution to the literature on transportation is that few studies have examined how such transformations fulfill their main policy objectives. We use the City of Bergen in Norway as a case study to infer the extent to which policy objectives were achieved two years later. In early 2016, the city council transformed its flat-rate cordon toll ring into a congestion charging scheme. It entailed an increase in toll rates during rush hour and a decrease during non-rush hour periods. The primary aim was to reduce traffic levels entering the city center during rush hour and improve the inner city's air quality. A secondary objective was to maintain income at the current level to complete the preplanned and already sanctioned investment projects. We use traffic counts, NO2 and PM10 emission measurements, and annual toll income to evaluate how the congestion scheme performed two years after implementation. We find that (i) traffic levels during rush hour and non-rush hour periods were reduced by 12% and 2%, respectively, giving a grand reduction of 6%; (ii) the emissions in NO2 and PM10 were reduced by 6.3% and 11%, respectively; (iii) the toll income dropped by 13%, meaning that preplanned investments would not be implemented on time; and (iv) the use of other modes of transportation increased. Overall, congestion charging worked according to transportation economists' longstanding suggestions.

Abstract
Background The global healthcare burden of COVID19 pandemic has been unprecedented with a high mortality. Metabolomics, a powerful technique, has been increasingly utilized to study the host response to infections and for understanding the progression of multi-system disorders such as COVID-19. Analysis of the host metabolites in response to SARS-CoV-2 infection can provide a snapshot of the endogenous metabolic landscape of the host and its role in shaping the interaction with SARS-CoV-2. Disease severity and consequently the clinical outcomes may be associated with a metabolic imbalance related to amino acids, lipids, and energy-generating pathways. Hence, the host metabolome can help predict potential clinical risks and outcomes.Methods In this study, using a targeted metabolomics approach, we studied the metabolic signatures of COVID-19 patients and related it to disease severity and mortality. Blood plasma concentrations of metabolites were quantified through LC-MS using MxP Quant 500 kit, which has a coverage of 630 metabolites from 26 biochemical classes including distinct classes of lipids and small organic molecules. We then employed Kaplan-Meier survival analysis to investigate the correlation between various metabolic markers, and disease severity and patient outcomes.Results A comparison of survival rates between individuals with high levels of various metabolites (amino acids, tryptophan, kynurenine, serotonin, creatine, SDMA, ADMA, 1-MH, and indicators of carnitine palmitoyltransferase 1 and 2 enzymes) and those with low levels revealed statistically significant differences in survival outcomes. We further used four key metabolic markers (tryptophan, kynurenine, asymmetric dimethylarginine, and 1-Methylhistidine) to develop a COVID-19 mortality risk model through the application of multiple machine-learning methods.Conclusions In conclusion, these metabolic predictors of COVID19 can be further validated as potential biomarkers to identify patients at risk of poor outcomes. Finally, integrating machine learning models in metabolome analysis of COVID-19 patients can improve our understanding of disease severity and mortality by providing insights into the relationship between metabolites and the survival probability, which can help lead the development of clinical risk models and potential therapeutic strategies.

Abstract
Purpose
This study determines the prognostic impact of body mass index (BMI) in patients with hormone receptor-positive/human epidermal growth factor receptor-2-negative (HR+/HER2-) advanced (i.e. metastatic) breast cancer (ABC).
Methods
All patients diagnosed with HR+/HER2- ABC who received endocrine therapy with or without a cyclin-dependent kinase (CDK) 4/6 inhibitor as first-given systemic therapy between 2007 and 2020 in the Netherlands were identified from the Southeast Netherlands Advanced Breast Cancer (SONABRE) registry (NCT03577197). Patients with a recorded BMI were categorised as underweight (<18.5 kg/m2), normal weight (18.5-24.9 kg/m2), overweight (25-29.9 kg/m2), or obese (≥30 kg/m2). Overall survival (OS) and progression-free survival (PFS) were compared between BMI classes using multivariable Cox regression analyses.
Results
This study included 1,456 patients, of whom 35 were underweight, 580 normal weight, 479 overweight, and 362 obese. No differences in OS were observed between normal weight patients and respectively overweight (HR=0.99; 95% CI: 0.85-1.16) and obese patients (HR=1.04; 95% CI: 0.88-1.24). However, the OS of underweight patients (HR=1.45; 95% CI: 0.97-2.15) tended to be worse than the OS of normal weight patients. When compared with normal weight patients, the PFS was similar in underweight (HR=1.05; 95% CI: 0.73-1.51), overweight (HR=0.90; 95% CI: 0.79-1.03), and obese patients (HR=0.88; 95% CI: 0.76-1.02).
Conclusion In this study among 1,456 patients with HR+/HER2- ABC, overweight and obesity were prevalent, whereas underweight was uncommon. When compared with normal weight, overweight and obesity were not associated with either OS or PFS. However, underweight seemed to be an adverse prognostic factor for OS.
Development of control systems for laser powder bed fusion

Published: July 2023

Abstract
This article aims to highlight the development of an intermittent controller designed to compensate and rectify the lack of fusion (LoF) zones that induce during the LPBF process. The initial step involved the utilization of the Self-Organizing Map (SOM) algorithm to identify the location of LoF defects. Subsequently, the identified defects undergo clustering through the K-means algorithm to form a matrix of cells on the build plate. The center of each cell that encompasses the defective area is then selected as the optimal position for increasing laser power during the subsequence printed layer. To identify the optimum laser power value, various artificial voids, mimicking actual defects, are embedded in the coupons. The capping layer (a layer that covers the artificial void) is then manufactured with different laser powers to heal the underlying defects. Based on the optimum laser power and defect size, several controlling rules are defined to change the laser power in-situ in the targeted cells located within the capping layer of defects. The change in laser power is transferred as a Laser Correction File (LCF) to the actuator via the Message Queuing Telemetry Transport (MQTT) broker. Finally, the performance of the controller is evaluated by designing and fabricating two new sets of experiments, including artificial and randomized defects. The results are validated by performing a micro CT scan, in which the density of defects is analyzed on parts produced with and without the controller. The results suggest that the use of the controller increased the density of the sample with randomized defects by up to 1%.
Numerical simulation for investigating the impact of shot peening process parameters via surface reconstruction

Published: July 2023

Abstract
Shot peening is one of the most widely used surface strengthening processes. The shot peening process involves multiple process parameters, which have a complex and interdependent impact on the peening effects, including compressive residual stress distribution and surface roughness. Accurately predicting the influence of shot peening parameters on the shot peening effect is a tough challenge in the simulation. In this paper, a shot peening simulation model is developed to investigate the influence of peening process parameters. The model encompasses material, target surface, and shot stream modeling. A method is proposed to reconstruct target surface model based on real rough surface data obtained via confocal laser scanning microscope. Unlike similar surface models, such as the Gaussian model, the reconstructed surface model replicates the peaks and valleys of the target surface along with their exact locations. A random multiple-shot model incorporating the reconstructed surface with predefined target coverage is developed via Python in Abaqus. Experimental verification on TC4 titanium alloy targets validates the simulation accuracy. The effects of peening parameters (shot velocity, density, diameter, and initial surface roughness) on residual stress distribution and surface roughness are investigated via the established model. Results reveal the significant influence of shot velocity and the relatively minor impact of other parameters. Increasing the diameter, velocity, and density of the shots result in higher residual stress levels and surface roughness. Notably, excessive initial surface roughness leads to abnormal increases in surface compressive residual stress.
Introduction of Bessel higher-order cosh-Gaussian beam and its propagation through a paraxial ABCD optical system

Published: July 2023

Abstract
In this paper, we introduce a new laser beam called Bessel higher-order cosh-Gaussian (BHChG) beam and analyzed its propagation properties through a paraxial ABCD optical system. The analytical expression of the diffracted beam is derived based on the extended Huygens-Fresnel integral and some numerical examples of BHChG beam propagating in a free space, through a thin lens and a Fractional Fourier transform (FRFT) system are exposed. The results reveal that the behavior of the output BHChG beam is affected by the optical system and the source beam parameters. The propagation of some laser beams through a paraxial ABCD optical system is deduced as particular case from the present study such as the fundamental Gaussian beam, the Bessel-Gaussian beam, the cosh-Gaussian beam, the Bessel-cosh-Gaussian beam and the Higher-order-cosh-Gaussian beam. The outcomes can be helpful for free-space optical communication, remote sensing and optical micromanipulation.
A Digital Music-Based Mindfulness Intervention for Black Americans With Elevated Race-Based Anxiety: A Multiple-Baseline Pilot Study
Authors: Jones Grant , Herrmann Felipe , Nock Matthew K 
Published: July 2023

Background
Race-based anxiety is a substantial health issue for the Black community. Although mindfulness interventions have demonstrated efficacy for alleviating anxiety, three central barriers prevent Black Americans from accessing existing mindfulness treatments: high costs, excessive time commitments, and limited cultural relevance. There is a need for novel mindfulness interventions for the Black community that can overcome these barriers.

Objective
The goal of this web-based study was to examine the preliminary efficacy, feasibility, and acceptability of a novel digital music-based mindfulness intervention for middle-to-low-income Black Americans with elevated race-based anxiety.

Methods
This study used a nonconcurrent multiple-baseline design (n=5). The intervention featured contributions from Lama Rod Owens (a world-renowned meditation teacher and LA Times best-selling author) and Terry Edmonds (the former chief speechwriter for President Bill Clinton). We examined the effect of the intervention on state anxiety and assessed its feasibility and acceptability using quantitative and qualitative measures.

Results
Results revealed that administration of the intervention led to significant decreases in state anxiety (Tau-U range –0.75 to –0.38; P values<.001). Virtually all feasibility and acceptability metrics were high (ie, the average likelihood of recommending the intervention was 98 out of 100).

Conclusions
This study offers preliminary evidence that a digital music-based mindfulness intervention can decrease race-based anxiety in Black Americans. Future research is needed to replicate these results, test whether the intervention can elicit lasting changes in anxiety, assess mechanisms of change, and explore the efficacy of the intervention in real-world contexts.

A chronic medical condition known as hypertension (HT) is characterised by persistently high blood pressure (BP) in the arteries. Although HT is initially asymptomatic, it eventually develops into a significant risk factor for renal, cardiovascular, and cerebrovascular conditions, which in turn are major contributors to morbidity and mortality in industrialised nations. A complicated disorder called HT is thought to affect more than one-fourth of adult humans worldwide. Both its pathophysiology (primary and secondary HT) and the measurements of the resting blood pressure (elevated systolic, diastolic, and pulse pressure) are used to categories it. It results from a complex interplay between genes and a number of environmental risk factors, including as ageing, smoking, inactivity, being overweight or obese, eating too much salt, stress, depression, and anxiety. Millions of people are affected by anxiety and depressive disorders each year, which are the most often diagnosed mental illnesses. These conditions are both characterised by emotional, cognitive, psychomotor, and neurovegetative symptoms. Additionally, stress at work has been identified as a significant risk factor for heart disease (CVD) and HT. Despite the fact that numerous writers have looked into and proposed connections between HT, stress, anxiety, and depression over the past few decades, a complete knowledge of the underlying pathophysiological mechanisms has not yet been attained, particularly with regards to young people. The purpose of this study was to examine the role that stress and anxiety from the workplace play in the HT development of young students of health care professions as well as any potential links to early CVDs.

Abstract
Conventional plastics which are often used in everyday life cause the accumulation of plastic waste and cause environmental pollution problems because plastics are difficult to decompose by microorganisms. Bioplastic is one of the solutions used in reducing environmental pollution, its nature is easily degraded and decomposed by microorganisms in a fairly short time making the plastic environmentally friendly. The materials used in the manufacture of bioplastics in this study are corn starch and cellulose fibers which are extracted from wasted paper using the acetylation method. The general objective of this study was to determine the effect of adding cellulose fibers to bioplastic samples with glycerol acting as plasticizers. Bioplastic analysis is carried out by measuring the tensile strength test, water absorption test, biodegradation test, and observing the structure using an optical microscope. The best tensile strength test results were obtained in the addition of 2 grams of cellulose pulp, with a tensile strength value of 1.65 MPa and a percentage of the sample's elongation value of 25%. For the water absorption test with the smallest percentage was obtained the addition of 1 gram of pulp with a value of 35.48%. The best biodegradation test results were in the addition of 1 gram and 2 grams, with a degradation time of 13 days.
