2 Qutrit-Inspired Fully Self-Supervised Shallow Quantum Learning Network for Brain Tumor Segmentation
شبکه یادگیری کوانتومی کم عمق کاملاً خود نظارتی الهام گرفته از Qutrit برای تقسیم بندی تومور مغزی-2022
Classical self-supervised networks suffer from convergence problems and reduced segmentation accuracy due to forceful termination. Qubits or bilevel quantum bits often describe quantum neural network models. In this article, a novel self-supervised shallow learning network model exploiting the sophisticated three-level qutrit-inspired quantum information system, referred to as quantum fully self-supervised neural network (QFS-Net), is presented for automated segmentation of brain magnetic resonance (MR) images. The QFS-Net model comprises a trinity of a layered structure of qutrits interconnected through parametric Hadamard gates using an eight-connected secondorder neighborhood-based topology. The nonlinear transformation of the qutrit states allows the underlying quantum neural network model to encode the quantum states, thereby enabling a faster self-organized counterpropagation of these states between the layers without supervision. The suggested QFS-Net model is tailored and extensively validated on the Cancer Imaging Archive (TCIA) dataset collected from the Nature repository. The experimental results are also compared with state-of-theart supervised (U-Net and URes-Net architectures) and the selfsupervised QIS-Net model and its classical counterpart. Results shed promising segmented outcomes in detecting tumors in terms of dice similarity and accuracy with minimum human intervention and computational resources. The proposed QFS-Net is also investigated on natural gray-scale images from the Berkeley segmentation dataset and yields promising outcomes in segmentation, thereby demonstrating the robustness of the QFS-Net model.

3 Code as constitution: The negotiation of a uniform accounting code for U:S: railway corporations and the moral justification of stakeholder claims on wealth
کد به عنوان قانون اساسی: مذاکره در مورد یک کد حسابداری یکسان برای شرکت های راه آهن ایالات متحده و توجیه اخلاقی ادعاهای سهامداران در مورد ثروت-2021
Economic historians of the United States identify the railway industry of the nineteenth century as the birthplace of existing institutions of corporate finance, law, and labor relations (Chandler, 1990; Perrow, 2002; Thomas, 2011). This paper shows that the railway industry was also an important arena for the standardization of corporate accounting in the U. S., and that railway accountants played a significant role in the federal government’s earliest attempts to regulate large corporations. The paper describes how railway accountants worked with the first federal regulator of corporations, the Interstate Commerce Commission (ICC), created by act of Congress in 1887, to create a uniform accounting code for the railway industry. This code was designed by the prominent economist and ICC statistician Henry Carter Adams to serve as a mechanism for the administrative supervision of railway corporations: a “cognitive equivalent of a constitution” (Starr, 1987, p. 53) that would promote economic democracy by protecting the property rights of non-controlling stakeholders in the railway system: shippers who used the trains to send goods to markets, long-term investors in railway shares and bonds, consumers of shipped goods, and members of the communities that the railways connected and employed. Railway accountants working with Adams created the rules for answering “potentially divisive questions of fact” (Starr, 1987, p. 53) about who contributed how much to the assets and profits of the railway corporation, and thus provided moral justification for how claims on those assets and profits were distributed.

4 Educational Intervention to Strengthen Pediatric Postoperative Pain Management: A Cluster Randomized Trial
مداخله آموزشی برای تقویت مدیریت درد پس از عمل کودکان: یک آزمایش تصادفی خوشه ای-2021
Background: Pediatric postoperative pain is still undertreated. Aims: To assess whether educational intervention increases nurses’ knowledge and improves pediatric postoperative pain management.
Design: Cluster randomized controlled trial with three measurement points (baseline T1, 1 month after intervention T2, and 6 months after intervention T3). Participants/Subjects: The study was conducted in postanesthesia care units at six hospitals in Norway. Nurses working with children in the included units and children who were undergoing surgery were invited to participate in this study.
Methods: Nurses were cluster randomized by units to an intervention (n = 129) or a control group (n = 129). This allocation was blinded for participants at baseline. Data were collected using “The Pediatric Nurses’ Knowledge and Attitudes Survey Regarding Pain: Norwegian Version” (primary outcome), observations of nurses’ clinical practice, and interviews with children. The intervention included an educational day, clinical supervision, and reminders.
Results: At baseline 193 nurses completed the survey (75% response rate), 143 responded at T2, and 107 at T3. Observations of nurses’ (n = 138) clinical practice included 588 children, and 38 children were interviewed. The knowledge level increased from T1 to T3 in both groups, but there was no statistically significant difference between the groups. In the intervention group, there was an improvement between T1 and T2 in the total PNKAS-N score (70% vs. 83%), observed increase use of pain assessment tools (17% vs. 39%), and children experienced less moderate-to-severe pain.
Conclusions: No significant difference was observed between the groups after intervention, but a positive change in knowledge and practice was revealed in both groups. Additional studies are needed to explore the most potent variables to strengthen pediatric postoperative pain management.

5 Fermentation 4:0, a case study on computer vision, soft sensor, connectivity, and control applied to the fermentation of a thraustochytrid
تخمیر 4:0 ، مطالعه موردی در مورد بینایی ماشین ، حسگر نرم ، اتصال و کنترل اعمال شده در تخمیر thraustochytrid-2021
In this work, the incorporation of I4.0 technologies in fermentation was studied. The work aimed to explore if I4.0 technologies could be used to solve problems related to the modernization of fermentation processes, particularly, 1) the interconnection of incompatible components (sensor, compressor, and feeding pump), 2) the implementation of fermentation conditions, relevant to the process efficiency, and 3) making the fermentation an I4.0 compatible component. The technologies were tested on a lab- scale thraustochytrid fermentation, an example of a complex and economically valuable bioprocess. The results showed that the incorporated I4.0 technologies allowed acquiring the dissolved oxygen values from an incompatible equipment screen and implementing a control algorithm for obtaining; high car- bon and nitrogen, and low dissolved oxygen concentration automatically after the growth phase. An automatic supervision tool allowed communicating relevant information about the fermentation state to humans and other computers. We conclude that incorporating I4.0 technologies in complex fermentation processes can improve process and equipment integration and allow the implementation of culture conditions that cannot be obtained using I2.0 and I3.0 technologies.© 2021 The Authors.

6 Research on prepaid account financing model based on embedded system and Internet of Things
تحقیق در مورد مدل تامین مالی پیش پرداخت بر اساس سیستم جاسازی شده و اینترنت اشیا-2021
Internet of Things (IoT) network interconnection to create objects and things will play the Internet to play an active role in the global network in the future. For the Internet of Things, which is widely adopted through funding models, it must be trusted in the IoT security infrastructure. Efficiently and Securely IoT is very important to define how each other can communicate with remote servers and get Exchange account informa- tion. Prepayments for effective financial management and an important choice for financial IoT for service providers and customers. However, it must be supported by real-time credit checking and costing. Internet re- sources are consumed by these real-time action stuff providers and impose high costs on the old system. To solve this problem, to propose the K Means Algorithm scalable accounting solutions, where the user is hosted each occupies a prepaid account, constitute the components of embedded systems. Based on each of our prepaid billing components’ supervision, it is at the same time consumed by the embedded system of all services, based on the calculation of the service packages consumed by the customer. Prepaid accounts are reassigned when the customer had sufficient credit to supplement their use and are allocated based on IoT services’ consumption. This work aims to reduce the cost of pre-paid services and ensure that service delivery is not to interfere with the charging unit. Also, embedded systems’ theoretical and experimental analysis shows that this work can store long-lived services on the Internet of Things to provide inexpensive accounting solutions.

7 Impact of fuel-efficient technology on automotive and fuel supply chain under government intervention: A case study
تأثیر فناوری کم مصرف بر روی زنجیره تأمین سوخت و خودرو تحت مداخله دولت: مطالعه موردی-2021
Transportation is one of the most influential factors in greenhouse gas emissions and global warming. This paper studies a network with an automotive supply chain that includes one supplier and one manufacturer next to a fuel supply chain consisting of a fuel manufacturer, operating under government intervention. The car manufacturer sells its green and non-green products under the dual-channel system with stochastic demand and demand leakage. To decrease greenhouse gas emissions, the car manufacturer invests in fuel-efficient technology for green products to reduce car fuel consumption. Moreover, due to increasing public awareness of environmental issues, the supplier invests in greening efforts to provide raw materials for fuel-efficient cars. The fuel manufacturer determines the fuel price under the government supervision and the government considers subsidies to support it. The fuel manufacturer has the opportunity to export the surplus fuel to other markets at a higher price. The government supports the production of fuel-efficient cars with two policies of subsidy-taxation and granting loans to customers. By doing so, the car manufacturer improves the level of fuel-efficient technology and the greening efforts of the supplier are increased. Additionally, the amount of fuel consumption in the internal market is reduced and the fuel manufacturer can export more fuel to the external market. As a result, the profit of all members increases simultaneously and environmental conditions improve. This model is studied under two scenarios for the distribution function of stochastic part of demand: (1) the Stackelberg scenario with complete information as a uniform distribution function and (2) the Nash scenario with partial information on a distribution-free approach. Some numerical examples based on real cases are provided to examine the capability of the proposed models. Finally, some sensitivity analyses are applied to the main parameters to extract several in-depth managerial concepts.

8 Accounting for financial stability: Bank disclosure and loss recognition in the financial crisis
حسابداری برای ثبات مالی: افشای بانکی و تشخیص از دست دادن در بحران مالی-2021
This paper examines banks’ disclosures and loss recognition in the 2007–2009 financial crisis and identifies several core issues for the link between accounting and financial stability. We show that, going into the financial crisis, banks’ disclosures about relevant risk exposures were relatively sparse. Such disclosures came later after major concerns about banks’ exposures had arisen in markets. The recognition of loan losses also was slow and delayed relative to prevailing market expectations. Among the possible explanations for this evidence, our analysis indicates that banks’ reporting incentives played a key role, which has important implications for bank supervision and the new expected loss model for loan accounting. We also provide evidence that shielding regulatory capital from accounting losses through prudential filters can dampen banks’ incentives for corrective actions. Overall, our analysis reveals several significant challenges if accounting and financial reporting are to contribute to financial stability.

9 Model-free control method based on reinforcement learning for building cooling water systems: Validation by measured data-based simulation
روش کنترل بدون مدل مبتنی بر یادگیری تقویتی برای برای ساخت سیستم های آب خنک کننده : اعتبار سنجی با شبیه سازی مبتنی بر داده اندازه گیری شده-2020
In the domain of optimal control for building HVAC systems, the performance of model-based control has been widely investigated and validated. However, the performance of model-based control highly depends on an accurate system performance model and sufficient sensors, which are difficult to obtain for certain buildings. To tackle this problem, a model-free optimal control method based on reinforcement learning is proposed to control the building cooling water system. In the proposed method, the wet bulb temperature and system cooling load are taken as the states, the frequencies of fans and pumps are the actions, and the reward is the system COP (i.e., the comprehensive COP of chillers, cooling water pumps, and cooling towers). The proposed method is based on Q-learning. Validated with the measured data from a real central chilled water system, a three-month measured data-based simulation is conducted under the supervision of four types of controllers: basic controller, local feedback controller, model-based controller, and the proposed model-free controller. Compared with the basic controller, the model-free controller can conserve 11% of the system energy in the first applied cooling season, which is greater than that of the local feedback controller (7%) but less than that of the model-based controller (14%). Moreover, the energy saving rate of the model-free controller could reach 12% in the second applied cooling season, after which the energy saving rate gets stabilized. Although the energy conservation performance of the model-free controller is inferior to that of the model-based controller, the model-free controller requires less a priori knowledge and sensors, which makes it promising for application in buildings for which the lack of accurate system performance models or sensors is an obstacle. Moreover, the results suggest that for a central chilled water system with a designed peak cooling load close to 20 0 0 kW, three months of learning during the cooling season is sufficient to develop a good model-free controller with an acceptable performance.

10 The CV effect: To what extent does the chance to reorganize depend on a bankruptcy judges profile?
اثر CV: تا چه حد شانس سازماندهی مجدد به مشخصات قضات ورشکستگی بستگی دارد؟-2020
This study explores the link between the individual profiles of French commercial judges and the bankruptcy cases they supervised between 2006 and 2012. A “Curriculum Vitae effect” prevails: the chance to reorganize after filing for bankruptcy varies with the composition of the chambers. We also confirm the existence of a limited (but not marginal) appointment bias, suggesting that bankruptcy cases are not fully randomized across judges. Several variables accounting for the judges’ profiles are found to be significant. The presence of female judges increases the chances of a successful plan (for continuation). We find a similar influence of the judges’ managerial skills and of the highest academic profiles. However, a mismatch between the judges’ profiles (mostly oriented toward big businesses) and bankrupt firms (closer to small and medium-sized enterprises) undermines the probability of reorganizing. We also focus on the two main filters for reorganization: i) the decision to open an observation period, and ii) the court supervision of such a period. Our findings provide normative recommendations to better align lay justice with litigants’ needs. The results from France can be extended to other mixed bankruptcy systems
