DRLAR: A deep reinforcement learning-based adaptive routing framework for network-on-chips

Adaptive routing plays a pivotal role in the overall performance of Network-on-Chips (NoCs). However, with many-core architectures supporting complex and constantly changing traffic patterns for emerging applications, this aspect presents significant challenges. Our meticulous examination and analysis of existing heuristic adaptive routing algorithms revealed three key limiting factors: single network status metric, lack of system feedback awareness, and lack of ability to customize. Reinforcement Learning (RL) methods have demonstrated promising opportunities for exploring adaptive routing design. Deep reinforcement learning (DRL) techniques, in particular, enable efficient exploration in adaptive routing design spaces where heuristic strategies may be inadequate. This paper proposes a novel deep reinforcement learning framework for adaptive routing called DRLAR that is suitable for diversified traffic patterns and resolves multi-objective optimization simultaneously. DRLAR formulates routing as an agent, which makes routing decisions based on autonomous learning using multiple network state features and system-level feedback information. We conduct extensive experiments against state-of-the-art routing algorithms to evaluate our design. The results show that DRLAR reduces packet latency by an average of 33.3%, achieving a reduction of 41.6% and 10.5% on average under heavy synthetic traffic and the PARSEC 2.1 benchmark, respectively. We also perform a cost analysis to validate the potential implementation of DRLAR on NoCs with low computational, storage, and power.

A cost analysis of upscaling access to continuity of midwifery carer: Population-based microsimulation in Queensland, Australia

ObjectiveTo quantify the economic impact of upscaling access to continuity of midwifery carer, compared with current standard maternity care, from the perspective of the public health care system. MethodsWe created a static microsimulation model based on a whole-of-population linked administrative data set containing all public hospital births in one Australian state (Queensland) between July 2017 to June 2018 (n = 37,701). This model was weighted to represent projected State-level births between July 2023 and June 2031. Woman and infant health service costs (inpatient, outpatient and emergency department) during pregnancy and birth were summed. The base model represented current standard maternity care and a counterfactual model represented two hypothetical scenarios where 50% or 65% of women giving birth would access continuity of midwifery carer. Costs were reported in 2021/22 AUD. ResultsThe estimated cost savings to Queensland public hospital funders per pregnancy were $336 in 2023/24 and $546 with 50% access. With 65% access, the cost savings were estimated to be $534 per pregnancy in 2023/24 and $839 in 2030/31. A total State-level annual cost saving of $12 million in 2023/24 and $19 million in 2030/31 was estimated with 50% access. With 65% access, total State-level annual cost savings were estimated to be $19 million in 2023/24 and $30 million in 2030/31. ConclusionEnabling most childbearing women in Australia to access continuity of midwifery carer would realise significant cost savings for the public health care system by reducing the rate of operative birth.

Exploring the influence of activity participation on the economic value of nature-based recreation in the Sierra Nevada

A more comprehensive understanding of how recreational values and forest visitation rates vary across different activities enables forest managers to tailor conservation and management strategies to align with preferences among visitors, ensuring more effective allocation of budgetary resources. However, current research often focuses on only a few recreational activities, resulting in limited insights for forest managers. This study aims to expand the nature-based activities considered so that management can better serve the broader public. We conduct a travel cost analysis using a large survey-based dataset to estimate the value of nature-based recreation in national forests in the Sierra Nevada region and assess how these values differ across main activities. We categorize recreational activities into five broad groups (Passive, Active, Camping, Winter, and Other) to offer a comprehensive view of recreational preferences. A truncated negative binomial regression accounting for endogenous stratification is used to analyze the relationship between the number of trips to the forests, travel cost, activity categories, and socio-demographic variables. Our results suggest a mean consumer surplus (CS) of $65 per visit per person to national forests in the Sierra Nevada. Aggregated over annual per person visits, the total CS is approximately $313.3 million per year. Our findings reveal variations in CS across activity groups, with winter activities (e.g., skiing, snowboarding) and active activities (e.g., hiking, fishing) attracting the highest number of visits, and the highest total CS. Our results provide valuable insights for national forest managers, facilitating the strategic allocation of limited resources to recreational activities that maximize societal welfare.

Electric vehicle and photovoltaic advanced roles in enhancing the financial performance of a manufacturing and commercial setup

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network.

Wound vacuum-assisted closure temporization after tumor resection of soft tissue sarcomas-A cost analysis in a propensity-score matched population.

Vacuum-assisted closure (VAC) temporization is a technique associated with high local control rates used in myxofibrosarcoma. We sought to compare the costs and postoperative outcomes of VAC temporization and single-stage (SS) excision/reconstruction. We conducted a retrospective analysis of patients with myxofibrosarcoma surgically treated at our institution between 2000 and 2022. Variables of interest included total, direct, and indirect costs for initial episode of care, 90 days and 1 year after initial admission, and postoperative outcomes. Costs were compared between the VAC temporization and SS groups. After matching, 13 patients in the SS group and 23 in the VAC group were analyzed. We found no difference in median and mean total inpatient costs, between the VAC temporization and SS group. While total 90-day and 1-year costs were higher in the VAC group compared to the SS group, mean costs were similar. There were no differences in postoperative complications between groups. A subanalysis of the entire cohort (n = 139) revealed lower local recurrence and overall death rates in the VAC temporization group. VAC temporization had similar inpatient costs and postoperative outcomes toSS excision/reconstruction. While median 90-day and 1-year costs were higher in the VAC group, mean costs did not differ.

Techno-Economic Evaluation of a Residential Photovoltaic System: A Case Study From the Residential Complex Kass Suwailem in Hilla, Iraq

Recently, the construction of residential complexes has spread significantly in all cities of Iraq. Hence, incorporating renewable energy into residential buildings provides multiple advantages as an essential component of the global sustainability initiative. In this study, a techno-economic analysis of a photovoltaic (PV) system has been evaluated in residential buildings of Kass Suwailem I and II, Iraq-Hilla, as a case study. The evaluation involved the technical and economic feasibility of implementing a solar power generation system in this residential setting. Furthermore, it assessed the costs, benefits, and financial viability of installing and operating a PV system for electricity generation. The optimal size of the PV system based on the energy consumption, local solar irradiation levels, and electricity demand patterns for each apartment unit has been evaluated. For each apartment unit, the total PV system cost is assumed to be $12,470 consisting of a 14.7 kW array, 8-battery bank of 230 Ah each, controller, and 10 kW inverter. Life-Cycle Cost analysis has been employed to determine the comprehensive cost of the PV system, encompassing all expenditures accrued throughout its operational lifespan. The calculation of the installed PV system involves annual energy rationalization, along with determining the amount of cost reduction and comparing the system with a generator or any other source that uses fossil fuels.

Improved dual-threshold quantum image segmentation algorithm and simulation

Abstract Quantum image segmentation algorithm is crucial for quantum image processing. In this paper, a dual-threshold quantum image segmentation algorithm is designed and simulated in IBM Quantum Experience (IBM Q) platform, which can segment a complex image into three parts using fewer quantum bits. In our algorithm, given a high threshold and a low threshold, grayscale values larger than the high threshold are set to the high threshold and grayscale values smaller than the low threshold are set to the low threshold, with no change for the part between the two thresholds. Then we use a low-cost quantum comparator and design a complete and scalable quantum image segmentation circuit. Analysis of the circuit cost shows that the quantum gates required for the circuit are only related to the grayscale range q and are independent of the image size. The feasibility of the algorithm and the correctness of the quantum circuit are verified by simulation in IBM Q platform, and finally the MSE, PSNR AND SSIM value of the image is analyzed to prove the effectiveness of the segmentation algorithm.

#2331 Distal arteriovenous fistulas for hemodialysis – too many interventions?

Abstract Background and Aims Distal arteriovenous fistula (dAVF) for haemodialysis (HD) is preferred due to lesser complications, despite greater risk of maturation failure. In HD patients, age and comorbid conditions increased the risk of access failure and number of procedures necessary for fistula patency. Preferred location for AVF poses a challenging decision. Advantages of dAVF must be taken into account although these may lead an unreasonably high number of interventions. Our aim was to determine time to functioning distal AFV in our centre and number of procedures necessary to achieve such status. Method Single centre retrospective analysis was performed on a cohort of patients submitted to distal AFV construction from 2015-2021. Success rate was defined as AFV patency in time for dialysis. Results Of 528 patients submitted to AVF construction from 2015 - 2021, 110 radiocephalic fistulas were seen, 59% male patients, mean age 68.5±12,0 yrs. Comorbidities were prevalent (80.9%, n=89), DM (54.6%) and HF (41.1%). Outcomes at 6 weeks were adequate maturation in 4.5% (n=59), 31.8% (n=35) late maturation (LM) and 14.5%(n=16) primary failure (PF). Causes of LM included inflow and outflow stenosis, 34.3% and 37.1%, respectively. LM (> 6 weeks) requiring no further intervention was seen in 28.6%. PF patients had smaller artery diameters on pre-operative US, with no statistical significance (0.23±0.07; 0.30 ± 0.2; p=0,375). Assisted patency rate was 78.2%. Number of procedures for access permeability was 1, 2 e 3 in 40%, 25.5% and 6.4%, respectively. Mean of 1,5±0,7 interventions per patient. Median time-to-adequate AFV was 2.0 (IQR 2,0 - 6,45) months. Success rate was 72,8%. Conclusion Outcomes at 6 weeks in our cohort were similar to those reported in literature. Timely referencing may increase access patency with resort to vascular intervention. Individualized management is essential, discussing risks and benefits taking into account the treatment burden associated with numerous procedures. Patency rates and outcomes after HD initiation and even cost analysis are essential to guide recommendations.

Variation in the Cost of Hip Arthroscopy for Labral Pathological Conditions: A Time-Driven Activity-Based Costing Analysis.

Despite growing interest in delivering high-value orthopaedic care, the costs associated with hip arthroscopy remain poorly understood. By employing time-driven activity-based costing (TDABC), we aimed to characterize the cost composition of hip arthroscopy for labral pathological conditions and to identify factors that drive variation in cost. Using TDABC, we measured the costs of 890 outpatient hip arthroscopy procedures for labral pathological conditions across 5 surgeons at 4 surgery centers from 2015 to 2022. All patients were ≥18 years old and were treated by surgeons who each performed ≥20 surgeries during the study period. Costs were normalized to protect the confidentiality of internal hospital cost data. Descriptive analyses and multivariable linear regression were performed to identify factors underlying cost variation. The study sample consisted of 515 women (57.9%) and 375 men (42.1%), with a mean age (and standard deviation) of 37.1 ± 12.7 years. Most of the procedures were performed in patients who were White (90.6%) or not Hispanic (93.4%). The normalized total cost of hip arthroscopy per procedure ranged from 43.4 to 203.7 (mean, 100 ± 24.2). Of the 3 phases of the care cycle, the intraoperative phase was identified as the largest generator of cost (>90%). On average, supply costs accounted for 48.8% of total costs, whereas labor costs accounted for 51.2%. A 2.5-fold variation between the 10th and 90th percentiles for total cost was attributed to supplies, which was greater than the 1.8-fold variation attributed to labor. Variation in total costs was most effectively explained by the labral management method (partial R2 = 0.332), operating surgeon (partial R2 = 0.326), osteoplasty type (partial R2 = 0.087), and surgery center (partial R2 = 0.086). Male gender (p < 0.001) and younger age (p = 0.032) were also associated with significantly increased costs. Finally, data trends revealed a shift toward labral preservation techniques over debridement during the study period (with the rate of such techniques increasing from 77.8% to 93.2%; Ptrend = 0.0039) and a strong correlation between later operative year and increased supply costs, labor costs, and operative time (p < 0.001 for each). By applying TDABC to outpatient hip arthroscopy, we identified wide patient-to-patient cost variation that was most effectively explained by the method of labral management, the operating surgeon, the osteoplasty type, and the surgery center. Given current procedural coding trends, declining reimbursements, and rising health-care costs, these insights may enable stakeholders to design bundled payment structures that better align reimbursements with costs.

Cost analyses for malaria molecular diagnosis for research planners in India and beyond

ABSTRACT Background Malaria elimination mandates early and accurate diagnosis of infection. Although malaria diagnosis is programmatically dependent on microscopy/RDTs, molecular diagnosis has much better diagnostic accuracy. Higher cost of molecular diagnoses is a recognized challenge for use at the point of care. Because funding is always a recognized constraint, we performed financial cost-analyses of available molecular platforms for better utilization of available budget. Methods Two strategies were applied to deduce the cost per sample. Strategy 1 included recurring components (RC) in minimum pack size, and biologist’s time whereas strategy 2 included only RC and non-recurring components and costs are calculated for sample sizes (1–1,000,000) to infer the sample size effect. Results Spin column-based manual DNA extraction (US$ 3.93 per sample) is the lowest-cost method, followed by magnetic bead-based automated, semi-automated, and PCI-based manual method. Further, DNA extraction cost per sample via spin column-based manual method and semi-automated method decreases with an increase in sample size up to 10,000. Real-time PCRs are ~ 2-fold more economical than conventional PCR, regardless of sample size. Conclusions This study is the first for malaria to estimate systematic molecular diagnosis financial costs. Kit-based and automated methods may replace conventional DNA extraction and amplification methods for a frugal high-throughput diagnosis.

A microcosting approach for planning and implementing community-based mental health prevention program: what does it cost?

BackgroundEstimating program costs when planning community-based mental health programs can be burdensome. Our aim was to retrospectively document the cost for the first year of planning and implementing Healthy Minds Healthy Communities (HMHC), a mental health promotion and prevention multi-level intervention initiative. This Program is among the first to use the Community Initiated Care (CIC) model in the US and is aimed at building community resilience and the capacity for communities to provide mental health support, particularly among those disproportionately impacted by COVID-19. Our objective is to share our methods for costing a program targeting 10 zip codes that are ethnically and linguistically diverse and provide an example for estimating the cost of a mental health prevention and promotion programs consisting of multiple evidence-based interventions.MethodsWe used a semi-structured interview process to collect cost data through the first year of program planning, start-up and initial implementation from key staff. We calculated costs for each activity, grouped them by major project categories, and identified the cost drivers of each category. We further validated cost estimates through extensive literature review. The cost analysis was done from the provider’s perspective, which included the implementing agency and its community partners. We delineated costs that were in-kind contributions to the program by other agency, and community partners. Sensitivity analyses were conducted to estimate uncertainty around parameters.ResultsFor the first year of the development and implementation of the program, (funded through program and in-kind) is estimated at $1,382,669 (2022 US$). The costs for the three main activity domains for this project are: project management $135,822, community engagement $364,216 and design and execution $756,934. Overall, the cost drivers for the first year of this intervention were: hiring and onboarding staff, in-person community building/learning sessions, communications and marketing, and intervention delivery.ConclusionImplementation of community-based mental health promotion and prevention programs, when utilizing a participatory approach, requires a significant amount of upfront investment in program planning and development. A large proportion of this investment tends to be human capital input. Developing partnerships is a successful strategy for defraying costs.

The economic impact of 14 compassionate use programs for medicines in Italy, in the perspective of the National Health Service

Background: Compassionate use programs (CUP) for medicines allow patients, not recruited in trials, accessing medicines before marketing approval. The evidence on the economic impact of CUP is limited to one paper that did not include the possible long-term economic impact of medicines used in CUP compared to alternative treatments, like avoided hospitalization costs. This paper aims at covering this information gap, updating and integrating the existing evidence, with a cost analysis in the perspective of the Italian National Health Service (SSN). Methods: Data were retrieved from the Roche CUP Database, the peer-reviewed literature (e.g. published cost-effectiveness studies, if any), the gray literature (e.g. regional documents for the alternative treatment cost) and unpublished data (e.g. cost-effectiveness analysis provided for price and reimbursement negotiation for medicines in CUP). Results: We retrieved data from 14 CUPs and 3,485 patients (70% affected by tumors) (Jan 2015-August 2022). The alternative treatment mean cost per patient ranged from € 11.1 k to € 18.8 k. The net economic benefit ranged from € 47 million to € 75 million (€ 13.5 k-€ 21.5 k per patient). Avoiding alternative treatments mostly contributes to the economic benefit. The long-term economic impact accounted for 20/30% of the net economic impact. The net economic benefit for cancer drugs ranged from € 12.6 million to € 40.0 million. Conclusions: Despite research limitations, this paper provides additional evidence on the economic impact of CUP in Italy. This could represent the first step of a broader analysis of the economic impact of early access schemes for drugs.

Comparative Analysis of Open v/s Protected Cut Flower Rose Farming in Karnataka, India

In India, the floriculture industry is the second largest in the world, trailing only China. The total area under flower crops during 2023-24 was 285,000 hectares; production of loose flowers was estimated to be 21.52 lakh metric tons, and cut-flowers were 645 metric tons. Both fresh and dried cut flowers lead floriculture exports from India. (NHB, 2023-24). Among the plethora of flowers, the rose stands out as a plant with hundreds of species and thousands of cultivars, many of which are native to Asia. These roses are not only extensively used in commercial perfumery and pharmaceuticals but also as commercial cut flower crops. In the current era of commercialization, rose cultivation has expanded to both protected and open-field methods. Therefore, this study was undertaken to analyze the Comparative Analysis of Open vs. Protected Cut Flower Rose Farming in Karnataka. The study was based on primary data collected from 40 farmers each from both the districts, namely Chikkaballapura and Bengaluru Rural. The data were analysed using cost and return analysis and capital budgeting techniques. The results obtained from this study indicated that the cultivation of roses was profitable under open and protected fields. But comparatively, the rate of return obtained from protected cultivation was higher, i.e., 54 per cent with a 1.58 B:C ratio, than open-field cultivation, i.e., 47 per cent with a 1.21 B:C ratio. Therefore, efforts should be made to educate the traditional rose farmers to adopt a better package of practices followed by protected farms and encourage them by providing cheaper institutional credit and subsidies.

Analysis of Costs Associated With Increased Length of Stay After Total Joint Arthroplasty at a Single Private Practice.

As the demand for total hip arthroplasty (THA) and total knee arthroplasty (TKA) increases, so does the financial burden of these services. Despite efforts to optimize spending and bundled care payments, THA and TKA costs still need to be assessed. Our study explores the relationship between perioperative costs and length of stay (LOS) for THA and TKA. A total of 614 patients undergoing THA or TKA at a single private practice with LOS from zero to 3 days were identified. All patients were insured by private or Medicare Advantage insurance from a single provider. Primary outcomes included total costs and their relationship with LOS, classified into surgeon reimbursement, facility costs, and anesthesia costs. Secondary outcomes included readmission rates and discharge disposition. Analyses involved Student t-test, analysis of variance, and chi-square tests. Longer LOS was associated with increased total, facility, and anesthesia costs. Costs for THA patients were stable except for reduced surgeon reimbursement with longer LOS. Patients undergoing TKA experienced an increase in facility costs with longer LOS. Total facility and anesthesia costs increased with LOS for Medicare Advantage patients, but surgeon reimbursement remained stable. Privately insured patients experienced higher total and facility costs but stable surgeon reimbursement and anesthesia costs regardless of LOS. Our study shows an increase in total cost with longer LOS, especially pronounced in privately insured patients. A notable reduction was observed in the surgeon reimbursement for Medicare Advantage patients with extended LOS. These findings underscore the need for efficient surgical practices and postoperative care strategies to optimize hospital stays and control costs.
