Genetic algorithmic based approach for multiple-objective probabilistic fractional programming problem involving discrete random variables
Authors: Belay Berhanu , Abebaw Adane
Published: September 2022

This manuscript presents a technique for solving a multiple-objective probabilistic fractional programming problem with discrete random variables. A multiple-objective probabilistic mathematical model is constructed with fractional objectives. In the model, some parameters of coefficients and right hand side parameters of restrictions are assumed as random variables having Pascal and Hyper geometric distributions. The feasibility of probabilistic constraints is checked by means of stochastic simulation. Genetic algorithm approach method is used to obtain the Pareto optimal solution of the proposed model without finding the deterministic model. Genetic algorithm parameters are fixed in all generation. The proposed method is coded by C++ programming language. To illustrate the method, a numerical example and practical example on the case of supply chain management are presented. The result shows that the values of the objective functions are conflicting each other.
Conceptualisation, estimation, and empirical analyses of land–sea convergenomics: A case study on Bohai Economic Rim cities
Authors: Yu Zhe , Di Qianbin
Published: September 2022

This study proposes a land–sea convergenomics model based on analyses of marine and terrestrial economies. A viscosity-based system of indices was constructed to evaluate the land–sea convergenomics of Bohai Economic Rim (BER) cities and was applied to analyse the viscosities of BER cities from 2009 to 2019. BER cities’ viscosities trended upward, although with significant disparities. The developmental fundamentals were high at the system level and grew steadily during the study period. Resource development was low with a slow growth rate. Industrial linkages grew significantly but exhibited minor fluctuations. Outcome creation began at a low level but grew steadily. Cluster analyses revealed that, overall, the development of land–sea convergenomics in the BER occurred in clusters, with viscosity distribution centred around three core cities: Tianjin, Qingdao, and Dalian. Due to regional disparities, the effects of labour productivity, science and technology investment, economic fundamentals, and energy efficiency on land–sea convergenomics were significantly differentiated.

Published: September 2022

The use of drug utilization management techniques such as formulary exclusions, prior authorizations, and step edits has risen sharply during the last decade, contributing to the growing burden on physicians and patients. Limited quantitative data exist, however, on physician perceptions of drug utilization management. A national survey was conducted between February 9 and March 30, 2021, targeting office-based physicians working in the United States to assess their perceptions on drug utilization management in their practice. Of the 742 physicians that participated in the study, over 80% reported deciding against prescribing certain treatments in anticipation of drug utilization management at least sometimes (>50% of the time). Despite utilization management having an impact on prescribing decisions, about half of physicians said that the utilization management policies they encounter rarely or never (0–25% of the time) align with clinical evidence.

It is well known that the presence of comorbidities and age-related health issues may hide biochemical and metabolic features triggered by SARS-CoV-2 infection and other diseases associated to hypoxia, as they are by themselves chronic inflammatory conditions that may potentially disturb metabolic homeostasis and thereby negatively impact on COVID-19 progression. To unveil the metabolic abnormalities inherent to hypoxemia caused by COVID-19, we here applied gas chromatography coupled to mass spectrometry to analyze the main metabolic changes exhibited by a population of male patients less than 50 years of age with mild/moderate and severe COVID-19 without pre-existing comorbidities known to predispose to life-threatening complications from this infection. Several differences in serum levels of particular metabolites between normal controls and patients with COVID-19 as well as between mild/moderate and severe COVID-19 were identified. These included increased glutamic acid and reduced glutamine, cystine, threonic acid, and proline levels. In particular, using the entire metabolomic fingerprint obtained, we observed that glutamine/glutamate metabolism was associated with disease severity as patients in the severe COVID-19 group presented the lowest and higher serum levels of these amino acids, respectively. These data highlight the hypoxia-derived metabolic alterations provoked by SARS-CoV-2 infection in the absence of pre-existing co-morbidities as well as the value of amino acid metabolism in determining reactive oxygen species recycling pathways, which when impaired may lead to increased oxidation of proteins and cell damage. They also provide insights on new supportive therapies for COVID-19 and other disorders that involve altered redox homeostasis and lower oxygen levels that may lead to better outcomes of disease severity.

Authors: Kajiwara Saito Mari , Morishima Toshitaka , Ma Chaochen , Koyama Shihoko , Miyashiro Isao
Published: September 2022

Background

The coronavirus disease 2019 (COVID-19) affected cancer care in Japan, but the detailed impact on cancer diagnosis and treatment is not well-understood. We aimed to assess the impact of COVID-19 on digestive cancer care in Osaka Prefecture, which has a population of 8.8 million.

Methods

We conducted a multi-center cohort study, using hospital-based cancer registry (HBCR) data linked to administrative data from 66 designated cancer care hospitals in Osaka. Records of patients diagnosed with cancer of the stomach, colorectum, esophagus, liver, gallbladder or pancreas were extracted from the HBCR data. Baseline characteristics, such as the number of diagnoses, routes to diagnosis and clinical stage, were compared between patients diagnosed in 2019 and those in 2020. We also compared treatment patterns such as the number of treatments (operations, endoscopic surgeries, chemotherapies, radiotherapies), pathological stage and time to treatment for each digestive cancer.

Results

In total, 62,609 eligible records were identified. The number of diagnoses decreased in 2020, ranging from -1.9% for pancreatic cancer to -12.7% for stomach cancer. Screen-detected cases decreased in stomach and colorectal cancer. The percentage of clinical stage III slightly increased across different cancers, although it was only significant for colorectal cancer. Among 52,741 records analyzed for treatment patterns, the relative decrease in radiotherapy was larger than for other treatments. The median time from diagnosis to operation was shortened by 2–5 days, which coincided with the decrease in operations.

Conclusion

The impact of COVID-19 on cancer care in 2020 was relatively mild compared with other countries but was apparent in Osaka. Further investigation is needed to determine the most affected populations.

Authors: Arango Álvarez Luisa Fernanda , Balbo Jose Tadeu
Published: September 2022

In addition to technical studies, bicycle paths should be a product of planning and investment policies considering the ability of projects to generate socioeconomic benefits, implementing policie’s objective analysis relevant to the feasibility of projects for the implementation of exclusive bike tracks.  In this paper the Non-Motorized Traffic (NTM) model of the HDM-4 (Highway Development and Management) software is applied for the analysis of different alternatives for bicycle lanes, evaluating aspects such as current and potential cyclists demand, operation speed, capital costs and economic profile of bicycle users. The combination of such variables leads to technical and economic alternatives whose analysis results relevant differences in their profitability indicators. The analyses were carried out considering two scenarios; the first comprises the analysis of the profitability of alternatives structured with normative guidelines that, in terms of speed, represent ideal operating conditions; the second scenario consists of a more realistic evaluation for the city of São Paulo, considering speed restrictions and diversifying the user profile according to the per capita income of the main regions of the city. The results reflect interregional diversity about the desirability of bikeway projects based solely on the monetary benefits of reduced travel times. The kern results point out financial risk of the projects as governed by speed and traffic, also requiring a demand of over 1000 bicycles/day and an operation that exceeds 8 km/h to support bicycle projects investments.

Published: September 2022

Hypertension as well as diabetes mellitus has been reported to be a major risk factor for deteriorating kidney functions. However, there is paucity of reports on renal functions in a co-existence of hypertension and diabetic condition, hence, this study evaluates renal functions in hypertensive and diabetic co-morbidity. Participants were categorised into healthy, hypertension, diabetes and hypertension with diabetes group. Blood pressure was measured as well as fasting blood glucose and blood samples were collected from each participant to assay renal function indices. The results showed that there was substantial uraemia as well as a significant reduction glomerular filtration rate in co-morbid hypertension and diabetic patients. Fasting blood glucose and mean arterial blood pressure were considerably elevated while creatinine concentration was not significantly altered in comorbid hypertension and diabetic patients. This study revealed that co-existence of hypertension and diabetes mellitus exacerbated renal dysfunction comparatively to hypertension and diabetes mellitus.
Comparing perceptions of nursing faculty and students to actual student performance in syringe measurement and use: An example of the Dunning-Kruger effect?
Authors: Shimony Kant Sarit , Woloski Wruble Anna
Published: September 2022

Introduction: A vital component of nursing education is the evaluation by faculty of student nurse’s skill competence. Erroneous estimations of skill competence, as in syringe measurements and dosages, can be critical to patient safety. The Dunning-Kruger effect describes the overestimation/underestimation of skill competence. It is the professional responsibility of faculty and students to be able to assess actual versus perceived competence levels accurately.
Purpose: The purpose of this study was to compare the perceptions of nursing faculty and nursing students to student actual competence in syringe measurement and usage.
Methods: A cross-sectional, descriptive, comparative study conducted in a School of Nursing Skills Laboratory. Participants included faculty and 3rd and 4th year nursing students.
Results: The study sample included 96 students and 30 faculty members. Significant differences were found between faculty perception and student perception of competence (p=0.001). The actual successful performance of all students was lower than expected; 3rd year students had a higher perception of their skill competence than their actual performance, and 4th year students performing at a lower level than 3rd year students (p=0.001).
Discussion: Nursing faculty educators and upper-class nursing students perceived a higher level of competence than actual performance. This supports the Dunning Kruger effect and behooves nursing faculty and students to be more precise in their assessments.
Conclusions: In today's milieu of online teaching, keen awareness and objectivity regarding clinical skills competence is imperative for client safety.  A longitudinal study measuring perception of competence as compared with actual skill performance is warranted.

TSG101 associates with PARP1 and is essential for PARylation and DNA damage‐induced NF‐κB activation
Authors: Tufan Ahmet Buğra , Lazarow Katina , Kolesnichenko Marina , Sporbert Anje , von Kries Jens Peter , Scheidereit Claus
Published: September 2022

In a genome‐wide screening for components of the dsDNA‐break‐induced IKK‐NF‐κB pathway, we identified scores of regulators, including tumor susceptibility gene TSG101. TSG101 is essential for DNA damage‐induced formation of cellular poly(ADP‐ribose) (PAR). TSG101 binds to PARP1 and is required for PARP1 activation. This function of TSG101 is independent of its role in the ESCRT‐I endosomal sorting complex. In the absence of TSG101, the PAR‐dependent formation of a nuclear PARP1‐IKKγ signalosome, which triggers IKK activation, is impaired. According to its requirement for PARP1 and NF‐κB activation, TSG101‐deficient cells are defective in DNA repair and apoptosis protection. Loss of TSG101 results in PARP1 trapping at damage sites and mimics the effect of pharmacological PARP inhibition. We also show that the loss of TSG101 in connection with inactivated tumor suppressors BRCA1/2 in breast cancer cells is lethal. Our results imply TSG101 as a therapeutic target to achieve synthetic lethality in cancer treatment.

Published: September 2022

A polyol-based ester was synthesized from biomass-derived bio-oil for application as a biolubricant. The bio-ester is biodegradable, non-toxic, and does not require mineral oil usage. Levulinic acid (LA), a major component obtained from bio-oil, was used for the catalytic esterification with two types of polyols, i.e., trimethylolpropane (TMP) and pentaerythritol (PE), in the presence of alumina-supported Cu(II), Co(II), and Fe(II) complexes as catalysts. Alumina-supported Cu(II), Co(II), and Fe(II) complexes [Cu(Tyr)(GA)]Cl-alumina, [Co(Tyr)(Amp)]Cl-alumina, and [Fe(Tyr)(Amp)]Cl-alumina were synthesized by the reaction of ligands [L-tyrosine (Tyr), Gallic acid (GA), and 2-aminopyridine (Amp)] with metal chloride salts. The catalysts were characterized by elemental analyses (CHN), magnetic susceptibility, Fourier transform infrared spectroscopy (FTIR), thermo-gravimetric analysis/differential thermal analysis (TGA/DTA), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray (EDX) techniques. Catalytic performances of the synthesized complexes were investigated via esterification of levulinic acid with trimethylolpropane and pentaerythritol. In addition, the two best catalysts, [Cu(Tyr)(GA)]Cl and [Co(Tyr)(Amp)]Cl-alumina, were further employed for the in situ hydrogenation of levulinate esters at 120 °C to 130 °C and 7 bar to 8 bar H2 pressure for upgrading in a specially designed reactor. The alumina-supported catalysts were active, reusable, and exhibited their efficiency as heterogeneous catalysts for esterification and hydrogenation reactions for synthesizing ester-based oils.
New method to evaluate the frictional behavior within the forming gap during the deep drawing process of paperboard
Authors: Lenske Alexander , Müller Tobias , Hauptmann Marek , Majschak Jens-Peter
Published: September 2022

To evaluate the influence of different normal forces and contact temperatures on the frictional behavior of paperboard during the deep drawing process, a new measurement punch was developed to measure the normal force, which induced the friction within the gap between the forming cavity and punch. The resulting dynamic coefficient of friction was calculated and reproduced via a new developed substitute test for the friction measurement device, which was first introduced in Lenske et al. (2017). The normal force within the forming gap during the deep drawing process was influenced by the blankholder force profile, the contact temperature, and the fiber direction. The friction measurements with the substitute test showed a strong dependency between the applied normal force and the dynamic coefficient of friction. Furthermore the frictional behavior was influenced by the contact temperature and the wrinkle formation.

Published: September 2022

Producing nanocellulose from lignocellulosic plants is difficult but can be achieved with microwave-assisted treatment. However, the changes in dimensions during the process have not been investigated thoroughly. In this study, kenaf bast was used to produce cellulose nanofibers using microwave, chemical, and ultrasonic treatments. Fiber sizes were monitored throughout the experiment using an optical microscope and scanning electron microscopy (SEM). The kenaf single fiber cells were also isolated and measured. The results showed that the duration of microwave treatment notably influenced the destruction of kenaf fibers, and the concentration of NaOH in the chemical treatment had only a limited effect on the reduction of kenaf particle size. Both the microwave and chemical treatments were able to destruct the kenaf fibers longitudinally, and the ultrasonic treatment was able to reduce cellulose particles from micro-size to nano-size.

The low competitiveness of superior products in West Java is caused by several things, such as the non-conducive macro economy, weak technology development, weak competitive climate (micro); and the inaccuracy of the business development strategy implemented by business actors and other shareholders. In addition to these things, there are several inhibiting factors in increasing the competitiveness of West Java's leading export products, among others, unsettled production factors, poor institutional factors, and the relationship and utilization of supporting industries that have not been maximized.

Refugees lose their networks and support systems on their journey from their home country. In addition, they may experience torture, trauma, and socio‐economic hardship. A critical question concerning refugee wellbeing is how refugee belonging, inclusivity, and community connectedness can be better understood, strengthened, and promoted. In this article, we discuss how members of the Tamil Seniors Group, supported by the NSW Service for the Treatment and Rehabilitation of Torture and Trauma Survivors (STARTTS), develop social networks in Australia. Based on two focus group discussions, this article analyses their experiences through the intersection of age and gender to elucidate the challenges and affordances of networking and establishing social relations in Australia.
Accessible and Inclusive Cities: Exposing Design and Leadership Challenges for Bunbury and Geelong

Published: September 2022

This article compares research identifying the systemic barriers to disability access and inclusion in two regional Australian cities, and discusses some of the leadership and design challenges that will need to be addressed by government and industry to embed universal design principles within the planning, development, and redevelopment of urban infrastructure. In Geelong, Victoria, given the often-opaque decision-making dynamics at play in the urban planning and development of cities, the disability community sought a more holistic and consultative approach to addressing access and inclusion. Systems-thinking for a collective impact approach was used to generate recommendations for action around improving universal design regulations, community attitudes to disability, access to information, accessible housing, partnerships, and disability employment. At Bunbury, Western Australia, a similar project analysed systemic factors affecting universal design at a local government level, and recommended a suite of safeguards for universal design including staff training, policies and procedures, best practice benchmarks, technical support and engagement in co-design. We describe the process followed in both studies to identify how, through collaborative and action-oriented research methods, the studies identified key technical, cultural, political, and structural changes required to achieve equitable access and inclusion in the urban landscape.
