A bi-objective model for designing a green closed-loop supply chain network in a petroleum complex considering transportation constraints: A case study
Authors: Vardan Fatemeh , Hosseini Seyed Mohammad Hassan 
Published: March 2024

Abstract

Environmental concerns and operational costs leave companies no choice but to apply the approach of supply chain management considering both environmental and cost aspects. Meanwhile, the petroleum industry as a main industry plays a vital role in Iran’s economy as well as CO2 emissions. This paper aims to propose a new mixed integer linear programming model for a closed-loop supply chain network design in an Iranian petroleum complex. We consider a four-echelon supply chain network including input feed suppliers, primary petroleum manufacturers, secondary petroleum manufacturers, and customers. In addition, collection and recycling centers are also considered for products that have reached the end of their life. To close the problem to real-world conditions, we consider different technologies and different types of capacity for candidate petrochemical complexes and different types of vehicles for transportation. All types of vehicles have a given capacity and differ in terms of cost and CO2 emissions. Two objective functions are considered for simultaneous optimization, which include total expected cost and total CO2 emissions. The model's efficiency is validated based on data from a real case in the production and distribution chain of a petroleum complex in Iran. The result represents the conflict between the two objective functions and the proposed model provided several options as Pareto solutions for decision makers. Moreover, sensitivity analysis represents the effect of variations in the capacity of domestic refineries, the capacity of vehicles, and the capacity of secondary petrochemical complexes on two objective functions and the final values of decision variables. Specifically, we find that changes in the capacity of refineries, causes a 12% change in the value of the emitted CO2 but the total expected cost doesn’t change significantly. Finally, managerial insights are gained through the numerical results.

Abstract

Soil nutrients can limit productivity on highly weathered soils, but vegetation can adopt a range of strategies to maintain productivity under low nutrient supply. Using a full nutrient flux approach, we examine nutrient use strategies across nine old-growth and logged lowland moist tropical forests in Malaysian Borneo. Soil nutrient availability was a weak predictor of productivity. We explored the reasons for this by examining the vegetation biogeochemical cycles of five key macro- and micronutrients. For nitrogen (N), we found very little evidence of nutrient limitation. Four nutrients showed evidence of shifting strategies under limitation, with clear evidence for quantifiable thresholds below which compensation strategies were invoked and contrasting resource optimization strategies employed for each nutrient. For potassium (K), enhanced leaf resorption was the primary strategy for coping with supply limitation. For calcium, shifting stoichiometry was the primary strategy. For phosphorus (P), a combination of both enhanced resorption and shifting stoichiometry was observed. The strongest relationships were found for P and K, with old-growth forests at this site showing some limitation and logged forests having sufficient nutrient supply. This study reveals the potential of nutrient flux approaches to describe the multifaceted and non-linear relationship between soil nutrient supply and uptake, and biomass productivity.

Abstract
Several aspects of the global biospheric carbon cycle are highly uncertain, including estimation of CO2 budgets at hemispheric scale by top-down inverse modelling approach. We use CO2 fluxes from a model intercomparison project (OCO-2_v10_MIP) that was conducted using long-term background station CO2 and total-column CO2 (XCO2) observations for the period 2015–2020. Total (ocean + land) CO2 flux and mean model-observed CO2 differences against 50 background sites exhibit statistically significant correlations for the northern and southern extra-tropics (latitude > 30o). Using these correlations, we define emergent constraints to calculate “best estimate” total CO2 fluxes. After correcting ocean fluxes and riverine carbon export, we estimate terrestrial CO2 fluxes or land carbon stockchange of -1.54 ± 1.18, -0.04 ± 1.11 and − 0.13 ± 0.27 PgC yr− 1 in the northern extra-tropics, tropics, and southern extra-tropics, respectively. These fluxes agree well with those based on national inventories and land surface observations, but suggest that CO2 inversion models generally overestimate northern extratropical uptake and tropical emissions.

Published: March 2024

Abstract

Hand visibility affects motor control, perception, and attention, as visual information is integrated into an internal model of somatomotor control. Spontaneous brain activity, i.e., at rest, in the absence of an active task, is correlated among somatomotor regions that are jointly activated during motor tasks. Recent studies suggest that spontaneous activity patterns do not only replay task activation patterns but also maintain a model of the statistical regularities (priors) of the body and environment, which may be used to predict upcoming behavior. We test whether spontaneous activity in the human somatomotor cortex is modulated by visual stimuli that display hands vs. non-hand stimuli and by the use/action they represent. We analyzed fMRI activity and multivariate pattern analysis to examine the similarity between spontaneous activity patterns and task-evoked patterns to the presentation of natural hands, robot hands, gloves, or control stimuli (food). In the left somatomotor cortex, we observed a stronger (multivoxel) spatial correlation between resting-state activity and natural hand picture patterns compared to other stimuli. We did not observe any task-rest similarity in the visual cortex. We conclude that spontaneous activity patterns in somatomotor brain regions code for the visual representation of human hands and their use.

Abstract

Introduction:
Human papillomavirus (HPV) vaccination protects against HPV-associated cancers and genital warts. Healthy People 2030 goal for HPV vaccine uptake is 80%, but as of 2021, only 58.5% of adolescents are up to date in Georgia. The purpose of the study is to assess the attitudes, vaccine practices, facilitators, and barriers to receiving the HPV vaccine in southwest Georgia.
Methods
We conducted 40 semi-structured interviews with three different audiences (young adults, parents, and providers and public health professionals) guided by the P3 (patient-, provider-, practice-levels) model and used deductive coding approach. Young adults and parents were interviewed to assess their perceived benefits, barriers, and susceptibility of the HPV vaccine. Providers and public health professionals were interviewed about facilitators and barriers of patients receiving the HPV vaccine in their communities.
Results
Out of the 40 interviews: 10 young adults, 20 parents, and 10 providers and public health professionals were interviewed. Emerging facilitator themes to increase the uptake of the HPV vaccine included existing knowledge (patient level), providers’ approach to the HPV vaccine recommendations (provider level) and immunization reminders (practice level). Barrier themes were lack of knowledge around HPV and the HPV vaccine (patient level), need for strong provider recommendation and discussing the vaccine with patients (provider level), and limited patient reminders and information (practice level).
Conclusions
These interviews revealed key themes around education, knowledge, importance of immunization reminders, and approaches to increasing the HPV vaccination in rural Georgia. This data can inform future interventions across all levels (patient, provider, practice, policy, etc.) to increase HPV vaccination rates in rural communities.

Published: March 2024

Abstract

Background
Preoperative hematological parameters are predictors of pathological features and recurrence-free survival (RFS) in various malignancies. However, comprehensive studies of preoperative indicators associated with papillary thyroid carcinoma (PTC) are scarce. The present study investigated the association between preoperative indicators and RFS in patients with PTC. Accordingly, we explored the clinical impact of the prognostic nutritional index (PNI) on lymph node metastasis and RFS in patients with PTC.
Methods
A total of 619 PTC patients were retrospectively reviewed between Jan 2013 and Dec 2017. Laboratory values were measured and calculated. Receiver operating characteristic curves were generated to calculate the cutoff value. Univariate and multivariate analyses using the COX proportional hazard model were performed for RFS. The effects of PNI and age on RFS were investigated by the Kaplan-Meier method. Clinical characteristics and PNI were tested with the chi-square test. Univariate and multivariate logistic analyses were conducted to evaluate the predictive value of PNI for lymph node metastasis.
Results
In the multivariate Cox analysis, age, PNI and lymph node metastasis were independent prognostic indicators for RFS. The Kaplan-Meier method showed that the lower PNI group and age older than 55 years group displayed poor RFS. A low preoperative PNI was remarkably correlated with age, sex, extrathyroidal invasion, T stage, N stage and TNM stage. PNI was the only preoperative hematological indicator for lateral lymph node metastasis.
Conclusions
Among the preoperative hematological indicators, PNI may serve as a promising and effective predictor for RFS and lateral lymph node metastasis in PTC patients.

Abstract

Thin-walled cylindrical rings with outer cross ribs (TCROCR) have the advantages of lightweight, high stiffness, and high bearing capacity, which is widely used in aerospace equipment. Usually, these kinds of parts are split manufacturing with welding, and integrated manufacturing has received more attention now. Spin-extrusion forming (SEF) processing which draws inspiration from the principle of the gear-generating method is proposed and has been preliminarily applied. This method can improve rib height-width ratio and TCROCR can be formed efficiently and integrally. However, as a new method, how to design the target parts geometry and how to determine the rib limit height to meet the needs of the process still lacks systematic research. This article proposes an analytic model for predicting the rib height variation. The rib height of TCROCR is determined by two factors: one is the skin thickness reduction, which can be conveniently calculated based on the feeding amount of the feeding roll, and the other is the rib growth, which is caused by the material of the skin flowing towards the cavities. Therefore, the key to creating the analytic model is to obtain the material volume of the skin allocated to the longitudinal and transverse cavities, respectively. Utilizing Newton's second law, the proportion of material flowing into the transverse and longitudinal ribs can be correlated with the stress state of the skin, and the stress state during SEF processing can be calculated by the slab method and upper bound method. Then, the material flowing into the longitudinal ribs and transverse ribs can be obtained based on the principle of volume invariance, and the analytic model is established to predict the rib height variation. Subsequently, the accuracy of the analytic model is verified through experiments and simulations, and the growth patterns of rib height are detailed research.

Abstract
Trojan droppers consistently emerge as formidable malware threats, particularly within the Android ecosystem. Traditional malware detection strategies focus on identifying payloads upon execution or intercepting malicious downloads from compromised sources. Despite rigorous efforts to fortify network defenses against such droppers, these measures inadvertently highlight the necessity for exploring unconventional infiltration methodologies. This study expands on covert channel attacks, proposing the utilizationof gaming platforms, notably the classic Tetris arcade game, as a novel vector for malicious payload delivery. Our methodology diverges from conventional network-based attacks by embedding malicious payloads within the game’s Tetromino pieces. Through a custom-made application that masquerades as a benign Tetris variant, we facilitate the delivery and execution of malicious payloads on target devices within 3 to 7 minutes. This process is enabled by integrating the Shikata-Ga-Nai polymorphic encoder, an autosuggestion algorithm and mapping Tetromino shapes to a Meterpreter payload, thereby innovating payload delivery via gameplay suggestions. Our work provides a novel covert channel attack methodology which merges gamification with malicious payload delivery. To the best of our knowledge, this is the first study that introduces gamification and autosuggestion mechanisms for payload delivery. We present an in-depth analysis of the proposed attack, along with a number of countermeasures to mitigate such threats, emphasizing the importance of enhanced user awareness and prudent management of application permissions.

Published: March 2024

Abstract

The protein from black soldier fly larvae was used as a functional ingredient of a new fiber composite for wound scaffolding. Larvae protein powder (LP) was blended with biodegradable poly(ε-caprolactone) (PCL) and processed in an electrospinning machine using a coaxial feeding/mixing method to produce nanofibers approximately 100–350 nm in diameter. To improve the dispersion and interface bonding of various PCL/LP nanofiber components, a homemade compatibilizer, maleic anhydride-grafted poly(ε-caprolactone) (MPCL), was added to form MPCL/LP nanofibers. The structure, morphology, mechanical properties, water absorption, biocompatibility, wound healing, and biodegradability of PCL/LP and MPCL/LP nanofiber mats were investigated. The results showed enhanced adhesion in the MPCL/LP nanofiber mats compared to PCL/LP nanofiber mats; additionally, the MPCL/LP nanofibers exhibited better tensile strength at break of 0.7–2.2 and a Young's modulus of 9.0–22.8 MPa. Decomposition tests using a simulated body fluid revealed that the addition of LP enhanced the decomposition rate of both PCL/LP and MPCL/LP nanofiber mats and in vitro protein release. Cell proliferation and migration analysis indicated that PCL, MPCL, and their composites were biocompatible for fibroblast (FB) growth. Cell-cycle assays conducted by FBs on PCL/LP and MPCL/LP nanofiber samples showed normal cell growth distribution and biodegradability in a 30-day soil test. When the LP content was 20 wt.%, the degradation rate exceeded 50%. This suggests the potential of these materials as a new scaffold material and as a novel green nanofiber for environmental pollution reduction.
Epigenetic Control of Hyperuricemia and Gout by Gene Writer DNMT1 and RNA Editor ADAR1: Mechanism of Gout and Amyloid Dissolution in Down Syndrome

Published: March 2024

Abstract

Although DNA methyltransferase 1 (DNMT1) and RNA editor; ADAR triplications exist in Down syndrome (DS), their specific roles remain unclear. DNMT methylates DNA, yielding S-adenosine homocysteine (SAH), subsequently converted to homocysteine (Hcy) and adenosine by S-adenosine homocysteine (Hcy) hydrolase (SAHH). ADAR converts adenosine to inosine and uric acid. We hypothesized that targeting epigenetic regulators and RNA editor, and inhibiting Hcy and adenosine, could alleviate DS phenotype including the congenital heart disease (CHD). DS and wild type mice were treated with epigallocatechin gallate (EG), inhibitor of Hcy and adenosine. Specific substrate gel zymography identified matrix metalloproteinases (MMPs)/A Disintegrin and Metalloproteinase with Thrombospondin motifs (ADAMTS) activities and MMP12/ADAMTS12 and MMP13/ADAMTS13 levels were assessed via gel zymography. Cardiac levels of DNMT1, ADAR, tissue inhibitor of metalloproteinase 1 (TIMP1), SAHH, and ten eleven translocator (TET2); hydroxy methylation; a gene eraser was measured. Calcium urate deposits in heart tissue suggested gout mechanism in DS. Robust amyloid fibers in DS mouse brain cortex were most likely dissolved by ADAMTS as its levels were elevated in tissues, with a corresponding decrease in TIMP1 in the EG group. It appears that triplication of down syndrome cell adhesion molecule (DSCAM) and cell adhesion molecule 1 (CAM1) fragment also help dissolve amyloid fibers, thus suggesting ADAMTS13/TIMP1 ratio could predict plaque dissolution. Our results indicate that cystathionine-β synthase (CBS) inhibitor as a potential therapy for amyloid dissolution.
