The aim of the study was to estimate the economic damage by COPD, including direct medical and non-medical costs and indirect costs associated with premature deaths of working-age individuals.Materials and methods. First, estimation of the economic COPD burden in Astrakhan region (AR) was carried out using the clinical and economic analysis of the "cost of illness" (COI). Direct medical costs of inpatient, outpatient, ambulance and emergency medical care, as well as direct non-medical costs associated with the disability benefits payments, were taken into account. Indirect costs were defined as economic losses from undelivered products due to premature deaths of working-age individuals.Results. From 2015 to 2019, the economic COPD burden in AR amounted to 757.11 million rubles in total, which is equivalent to 0.03% of the gross regional product covering a five-year period of the study. Direct medical and non-medical costs totaled 178.02 million rubles. In the structure of direct medical expenses, expenses for inpatient, as well as ambulance and emergency medical care during the study period, increased by 92.5% and 45.5%, respectively. While the costs for the outpatient care decreased by 31.9%, the increase in direct non-medical costs associated with the disability benefits payments, increased by 5.1% (2019). Indirect losses amounted to 579.09 million rubles.Conclusion. The structure of the main damage is dominated by indirect losses in the economy associated with premature deaths of working-age individuals. In the structure of direct medical costs, inpatient care costs prevailed. These studies indicate the need to continue an advanced analysis of the economic burden of COPD, as well as to optimize the treatment and prevention of the exacerbations development of this disease.
Proposing Notaries’ Deed Digitalization in Indonesia: A Legal Perspective
Authors: Agustin Ika Yuli , Anand Ghansham 
Published: July 2021

Along with emerging technology, a notary public's role should adjust this changing development, mainly dealing with a deed. Technological development inevitably impacts the role of a notary public and the future digitization of notarial deeds. To date, notaries in Indonesia remain implementing laws and regulations that have not been changed. In contrast, technological development has shifted rapidly, especially on the notaries' task in appearing, reading, signing, and using stamps. This study aimed to identify the challenges of implementing notaries’ deed digitalization by taking into account rapid technological development. With legal research, this study showed that as a consequence of technological development, notarial functions’ disruption in Indonesia evoked a concept of a cyber notary, an idea of notarial function through an online system. As it has flourished globally, digital disruptions had brought out an electronic system that changed the implementation of works, business, professions, and functions, mainly to notarial functions. Nevertheless, no specific rules were established to amend Notary Law 02/2014, particularly to the requisites of authentic deeds by a cyber notary. Indonesia applied some restrictions on technology to maintain the legality of authentic deeds to place the notarial profession as a public official consistently.

Published: July 2021

One of the main elements in corruption is the loss of state finances. It results in confusion impacting law enforcement officials' performance in eradicating corruption. In Indonesia, the Supreme Audit Agency (BPK) is an institution authorized to assess state financial losses. In practice, the Financial and Development Supervisory Agency (BPKP) is another institution with similar power. This study analyzed which institutions have the more appropriate power in determining state financial losses in corruption. Using legal research with statutory and conceptual approaches, this study showed that the BPK is an institution granted the constitutional power to examine state finances' management and responsibility, asserting its more legitimate institution to handle the power to assess the financial losses. Consequently, the BPK is the only state institution that can determine state financial losses. At the same time, the BPKP is only authorized to assess or audit the calculation of state financial losses as an indication of irregularities detrimental to state finances. This study concluded that only the BPK can assess and determine state financial losses used in examining the alleged corruption before the court.

Tracking Pandemic Severity Using Data on the Age Structure of Mortality: Lessons From the 1918 Influenza Pandemic in Michigan
Authors: Chandra Siddharth , Christensen Julia 
Published: July 2021

Objectives. To test whether distortions in the age structure of mortality during the 1918 influenza pandemic in Michigan tracked the severity of the pandemic. Methods. We calculated monthly excess deaths during the period of 1918 to 1920 by using monthly data on all-cause deaths for the period of 1912 to 1920 in Michigan. Next, we measured distortions in the age distribution of deaths by using the Kuiper goodness-of-fit test statistic comparing the monthly distribution of deaths by age in 1918 to 1920 with the baseline distribution for the corresponding month for 1912 to 1917. Results. Monthly distortions in the age distribution of deaths were correlated with excess deaths for the period of 1918 to 1920 in Michigan (r = 0.83; P < .001). Conclusions. Distortions in the age distribution of deaths tracked variations in the severity of the 1918 influenza pandemic. Public Health Implications. It may be possible to track the severity of pandemic activity with age-at-death data by identifying distortions in the age distribution of deaths. Public health authorities should explore the application of this approach to tracking the COVID-19 pandemic in the absence of complete data coverage or accurate cause-of-death data.

Published: July 2021

Since its founding, the US government has sorted people into racial/ethnic categories for the purpose of allowing or disallowing their access to social services and protections. The current Office of Management and Budget racial/ethnic categories originated in a dominant racial narrative that assumed a binary biological difference between Whites and non-Whites, with a hard-edged separation between them. There is debate about their continued use in researching group differences in mortality profiles and health outcomes: should we use them with modifications, cease using them entirely, or develop a new epistemology of human similarities and differences? This essay offers a research framework for including in these debates the daily lived experiences of the 110 million racialized non-White Americans whose lived experiences are the legacy of historically limited access to society’s services and protections. The experience of Latinos in California is used to illustrate the major elements of this framework that may have an effect on mortality and health outcomes: a subaltern fuzzy-edged multivalent racial narrative, agency, voice, and community and cultural resilience.

Published: July 2021

Background:
The evidence for the treatment of acceptably reduced intra-articular distal radial fractures remains inconclusive. We therefore compared the functional outcomes of cast immobilization (nonoperative) and volar plate fixation (operative) for patients with these fractures.

Methods:
This multicenter randomized controlled trial enrolled patients between 18 and 75 years old with an acceptably reduced intra-articular distal radial fracture. Patients were randomized to nonoperative treatment or to operative treatment. The primary outcome measure was the Patient-Rated Wrist Evaluation (PRWE) score after 12 months. Secondary outcome measures were the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire; the Short Form-36 (SF-36) questionnaire; a visual analog scale for pain; range of motion; grip strength; radiographic parameters; and complications. Analyses followed the intention-to-treat principle.

Results:
A total of 96 patients were randomized, and 90 (46 in the nonoperative group and 44 in the operative group) were included in the analysis. Patients treated in the operative group had significantly better functional outcomes measured with the PRWE at 6 weeks, 3 months, 6 months, and 1 year. Additionally, a 28% rate of subsequent surgery was identified in the nonoperative group.

Conclusions:
Adult patients with an acceptably reduced intra-articular distal radial fracture have better functional outcomes for 12 months when treated operatively instead of nonoperatively. We therefore recommend surgical treatment for patients with these fractures.

Capsular Repair During Hip Arthroscopy Demonstrates Restoration of Axial Distraction Resistance in an in Vivo Intraoperative Testing Model
Authors: O’Neill Dillon C. , Tomasevich Kelly M. , Mortensen Alexander J. , Featherall Joseph , Ohlsen Suzanna M. , Aoki Stephen K. 
Published: July 2021

Background:
Cadaveric models demonstrate that failure of hip capsular repair is dependent on the robustness of the repair construct. In vivo data on capsular repair construct efficacy are limited. We investigated the effect of a figure-of-8 capsular repair on hip distraction resistance relative to native and post-capsulotomy states. We hypothesized that an unrepaired capsulotomy would demonstrate increased axial distraction compared with the native state and that capsular repair would restore distraction resistance to native levels.

Methods:
Patients undergoing primary hip arthroscopy by a single surgeon were prospectively enrolled between March 2020 and June 2020. Prior to any instrumentation, fluoroscopic images of the operative hip were obtained at 12.5-lbs (5.7-kg) traction intervals, up to 100 lbs (45.4 kg). Anterolateral, modified anterior, and distal anterolateral portals were established. Following interportal capsulotomy, labral repair, and osteochondroplasty, fluoroscopic images were reobtained at each traction interval. Capsular repair was performed with use of a figure-of-8 suture configuration. Traction was reapplied and fluoroscopic images were again obtained. Joint distraction distance was measured at each traction interval for all 3 capsular states. Anteroposterior pelvic radiographs were utilized to scale fluoroscopic images to obtain joint space measurements in millimeters.

Results:
A total of 31 hips in 31 patients were included. Capsulotomy resulted in significant increases in distraction distance from 25 (11.3 kg) to 100 lbs of traction compared with both native and capsular repair states (all comparisons, p ≤ 0.017). Capsular repair yielded a significantly greater distraction distance compared with the native state at 37.5 lbs (17.0 kg; 5.49 versus 4.98 mm, respectively; p = 0.012) and 50 lbs (22.7 kg; 6.08 versus 5.35 mm; p < 0.001). The mean difference in distraction distance between native and capsular repair states from 25 to 100 lbs of traction was 0.01 mm.

Conclusions:
This in vivo model demonstrates that an unrepaired interportal capsulotomy significantly increases axial distraction distance compared with the native, intact hip capsule. Performing a complete capsular closure reconstitutes resistance to axial distraction intraoperatively. Future research should evaluate the in vivo effects and associated clinical outcomes of other published capsular repair techniques and assess the durability of capsular repairs over time.
A Hashing Power Allocation Game with and without Risk-free Asset
Authors: Cheng Yukun , Du Donglei , Han Qiaoming 
Published: July 2021

Abstract
Miners in various blockchain-backed cryptocurrency networks compete to maintain the validity of the underlying distributed ledgers to earn the bootstrapped cryptocurrencies. With limited hashing power, each miner needs to decide how to allocate their resource to different cryptocurrencies so as to achieve the best overall payoff. Together all the miners form a hashing power allocation game. We consider two settings of the game, depending on whether each miner can allocate their fund to a risk-free asset or not. We show that this game admits unique pure Nash equilibrium in closed-form for both settings.
The Depth to Magnetic Sources in the Arctic and ItsRelationshipwith Some Parameters of the Lithosphere
Authors: Seredkina A.I. , Filippov S.V. 
Published: July 2021

Abstract––The depth to magnetic sources in twenty Arctic tectonic provinces is determined from azimuthally averaged Fourier power spectra of geomagnetic anomalies according to the EMAG2v3 and WDMAM 2.0 global models. The resulting depths to the centroid and bottom of the magnetic lithosphere are more reliable than the depth to the upper magnetic boundary. The depth to the bottom of magnetic sources, corresponding to the Curie point depth, varies from 25.3 to 38.1 km in different provinces. The Curie point depth estimates are correlated with several parameters of the lithosphere. They are directly proportional to the lithospheric thickness and inversely proportional to average upper mantle temperatures, but the relationship with the intensity of long-wavelength satellite magnetic anomalies and crustal thickness is poor. The magnetic sources are located at crustal depths in most of the provinces, but the upper mantle may be magnetic beneath deep-water oceanic basins and the Laptev Sea. The results for the Laptev Sea shelf support a passive mechanism of current lithospheric extension in the area.
Palinostratigraphy and Paleoenvironments in the Gorodishchi Section (Middle Volga River Region, Kimmeridgian–Hauterivian)
Authors: Pestchevitskaya E.B. 
Published: July 2021

Abstract
—Eight dinocyst-based and three spore- and pollen-based biostratigraphic units are defined in the Kimmeridgian, Volgian, and Hauterivian of the Gorodishchi section, based on a biostratigraphic analysis of the successions of marine and terrestrial palynomorphs. Algological assemblages are described in more detail, and additional criteria for the definition of dinocyst zones established by previous researches are given. A more detailed biostratigraphic subdivision of the middle part of the Volgian is proposed. A local dinocyst zone in the Hauterivian and a biostratigraphic succession of spore–pollen units in the entire section are described for the first time. The research results demonstrate that the boundaries of many palynostratigraphic units exhibit a considerable correlation potential. Based on a biofacies analysis of the microphytoplankton, the dynamics of transgressive–regressive events is studied in relation to the accompanying oxygen and trophic conditions. Possible relationships between marine paleoenvironments and climatic changes reconstructed on the basis of spore–pol­len data are discussed.
A Revised Gassmann Fluid Replacement Model Based on Neutron-Density Logs in Shaly Sandstone Reservoirs
Authors: Chakraborty Shantanu , Mondal Samit , Chatterjee Rima 
Published: July 2021

Summary
Fluid-replacement modeling (FRM) is a fundamental step in rock physics scenario modeling. The results help to conduct forward modeling for prediction of seismic signatures. Further, the analysis of the results improves the accuracy of quantitative interpretation and leads to an updated reservoir characterization. While modeling for different possible reservoir pore fluid scenarios, the quality of the results largely depends on the accuracy of the FRM. Gassmann (1951)fluid-replacement modeling (GFRM) is one of the widely adopted methods across the oil and gas industry. However, the Gassmann method assumes the reservoir as clean sandstone with connected pores. This causes Gassmann fluid-replacement results to overestimate the fluid effect in shaly sandstones. This study uses neutron and density logs to correct the overestimated results in shaly sandstone reservoirs. Due to the nature of these recordings, both of these log readings have close dependencies on the presence of shale. When the logs are plotted in a justified scale, the differences between the logs provide an accurate measurement of shaliness within the reservoir. The study has formulated a weight factor using the logs, which has further been used to scale the overestimated Gassmann-modeled fluid effect. The results of the revised method are independent of type of clay presence and associated effective porosity. Moreover, the corrected FRM results from the revised Gassmann method shows good agreement with rock physical interpretation of shaly sandstone reservoirs.

Abstract
Objective: The purpose of this study was to evaluate the usability and feasibility of smart glasses for team-based simulations constructed using a high-fidelity simulator. Methods: Two scenarios of patients with arrhythmia were developed to establish the process for interprofessional interaction via smart-glass in 15 hour simulation training. Three to four participants made a team and took roles of either remote supporter and bad-side trainee with smart-glass. Usability, attitudes towards interprofessional health care team and learning satisfaction were assessed. A scale for software evaluation was used to obtain quantitative data and essay questionnaire were used to assess usability and feasibility of current program. Using SPSS (version 25.0), statistical analysis was conducted. Results: Data were obtained from 31 participants. The current program was given an easy to use (3.61±0.95) rating, and the users reported feeling confident during use (3.90±0.87). Participants responded positively to long-term use (3.26±0.89) and low levels of physical discomfort (1.96±1.06). The likability of the smart glasses-based simulation was high, with a high rating for satisfaction (4.65±0.55). The majority (84%) of subjects provided favorable responses to their overall experience with high expectations for improving safety in future clinical practice. Key barriers and challenges of the current program include unstable internet connection, poor resolution and display, and physical discomfort of the smart glasses with accessories. Conclusion: We determined the feasibility and acceptability of smart glasses for interprofessional interaction within a team-based simulation environment. Participants responded favorably toward a smart glasses-based simulation learning environment that would be applicable in clinical settings.

Published: July 2021

Abstract
Software-defined networking (SDN) provides many benefits, including traffic programmability, agility, and network automation. However, budget constraints burdened with technical (e.g., scalability, fault tolerance, security issues) and, sometimes, business challenges (user acceptance and confidence of network operators) make providers indecisive for full SDN deployment. Therefore, incremental deployment of SDN functionality through the placement of a limited set of SDN devices among traditional devices represents a rational and efficient environment that can offer customers modern and more data-intensive services. However, while hybrid SDN provides many benefits, it also has specific challenges addressed in the literature. This paper answers one of these challenges by presenting the research and development of a new load balancing scheme in the hybrid SDN environment built with a minimal SDN device set (controller and one switch). We propose a novel load balancing scheme to monitor current server load indicators and apply multi-parameter metrics for scheduling connections to balance the load on the servers as efficiently as possible. The base of the new load balancing scheme is continuous monitoring of server load indicators and implementations of multi-parameter metrics (CPU load, I/O Read, I/O Write, Link Upload, Link Download) for scheduling connections. The testing performed on servers aims to balance the server's load as efficiently as possible. The obtained results have shown that this mechanism achieves better results than existing load balancing schemes in traditional and SDN networks. Moreover, a proposed load balancing scheme can be used with various services and applied in any client-server environment.
