Design a decentralized secure access control network using blockchain on a cloud platform
Authors: CH RAVIKUMAR 
Published: September 2022

Abstract
The cloud storage framework offers a pay-on-demand capacity model with low registration costs. Peer-to-peer distributed storage is an interesting application of blockchain as it provides a decentralized information storage space without the involvement of a Trusted Third Party or client-server engineering. Therefore, we propose blockchain-based decentralized engineering for a distributed storage framework based on Timely Ciphertext Strategy Feature-Based Encryption (TCP-ABE) with Distributed Hash Tables (DHT). In the proposed structure, the report's metadata would be stored on the blockchain, while the actual files would be distributed via his DHT under its uncommon domain name. Distributed information storage helps eliminate the most common information disappointments and power outages by improving information security, protection, and control. Additionally, it provides two important types of support to ensure the security element of the distributed storage framework. Introduce a decentralized access control system where the blockchain hub verifies the authenticity of joint accounts of clients and CP-ABE.

Published: September 2022

Abstract
Purpose
There exists continuous controversy regarding the effect of primary tumor resection (PTR) for stage IV colorectal cancer (CRC) patients. Little is known about how to predict the patients’ survival benefit from PTR. This study aimed to develop a tool for surgical benefit prediction.
Methods
Stage IV CRC patients diagnosed between 2010 and 2015 from the Surveillance, Epidemiology, and End Results database were included. After propensity score matching, patients receiving PTR that survived longer than the median cancer-specific survival (CSS) time of those who did not undergo PTR were considered to benefit from surgery. Logistic regression analysis identified prognostic factors influencing the surgical benefit, based on which a nomogram was constructed. A user-friendly webserver was then built for convenient clinical use. The predictive model was assessed using Harrell’s concordance index, calibration plot, receiver operative curve and decision curve analysis.
Results
The median CSS of the PTR group was 23 months, which was significantly longer than the non-PTR group (12 months, P < 0.001). In the PTR group, 32.9% of patients did not benefit from surgery. Logistic regression analysis identified age, tumor location, CEA level, histological grade, number of distant metastasis, and preoperative chemotherapy independently associated with surgical benefit. The established prognostic nomogram demonstrated satisfactory performance.
Conclusion
PTR was associated with prolonged survival in stage IV CRC. The proposed nomogram could be used as a risk-to-benefit assessment evidenced-based platform for selecting appropriate patients to undergo PTR.

Published: September 2022

Abstract
Purpose
To determine an early diagnostic indicator of biliary atresia (BA), we focused on morphological left-right differences of BA livers.
Methods
Of 74 infants with suspected BA at our hospital in the last 12 years, 25 met the conditions for investigation: 15 infants with BA (BA group) and 10 with other pathologies (non-BA group). CT volumetry of the liver in each patient was performed using a 3D image analysis system. Patient characteristics, blood data, and proportion of the left lateral segment to the total liver volume (LLS ratio) were compared between the two groups.
Results
Among the patient characteristics and liver function tests, only γ-glutamyl transpeptidase (GGT) were significantly higher in the BA group (p < 0.001). The LLS ratio was 0.321 (0.227–0.382) in the BA group and 0.243 (0.193–0.289) in the non-BA group (p = 0.01). The summary cut-off, area under the curve, sensitivity, and specificity were 0.322, 0.813, 53.3, and 100% for the LLS ratio and 94.26, 0.95, 86.7, and 100% for the GGT × LLS ratio, respectively.
Conclusions
The LLS ratio is highly specific and may be an early diagnostic predictor of BA. Moreover, this segmental LLS enlargement may be associated with the etiology of BA.
Use of minimally invasive cerclage wiring for displaced major fragments of femoral shaft fractures after intramedullary nailing promotes bone union and functional outcome
Authors: tao xingguang , Yang Qing 
Published: September 2022

AbstractBackground Femoral shaft fractures which are caused by high energy trauma, can be very challenging due to the large variability in fracture morphology and poor functional outcome. Displaced major fragments of femoral shaft fractures are difficult to manage after closed reduction and intramedullary nailing (IMN). The minimally invasive cerclage wiring (CW) procedure has developed to be an optimal tool for major fragments resetting and stabilization after IMN. However, argues continue for CW procedure is at potential risk of arterial injury, blood supply disruption, and delayed bone union or nonunion. The surgical algorithsm for femoral shaft fractures with displaced major fragments remains controversial. Thus, emphysis is placed on whether CW procedure can offer promotion of bone union rate and improvement of functional outcome without significant complications. Methods We perfomed a retrospective study on all patients of femoral shaft fractures with displaced major fragments between June 2015 and August 2019 in our trauma centre. Eligible patients were included and stratified into the cerlage wiring (CW) group and intramedulary nailing (IMN) group. Demographics, radiological data, callus formation, union time, and fuctional outcome were critically compared between two groups. Results 37 patients were included in the present study according to our inclusion/exclusion criteria, of which 16 (43.2%) were stratified into CW group, and 21 (56.8%) into IMN group. The Modified radiographic union score for femorae (mRUSH) in CW group and IMN group were compared to be sigfificantly different (11.94 ± 1.29 vs.7.95 ± 0.74, 6 months; 15.88 ± 0.50 vs. 10.33 ± 0.91, 12 months)(P < 0.0001). The mean union time was of significance between CW and IMN group (7.9 ± 3.2 months vs. 20.1 ± 8.48 months)(p < 0.0001). Bone union achieved at 12 months differed significantly between CW and IMN group (15 vs. 5) (p < 0.05). Harris Hip Score (HHS) in CW group was higher than IMN group (88.19 ± 4.69 vs. 76.81 ± 5.26, 12 months; 93.19 ± 4.68 vs. 87.57 ± 5.38, 24 months) significantly (P < 0.01), respectively. So was the Hospital for Special Surgery Knee Score (HSS) in CW and IMN group (78.50 ± 5.65 vs. 67.71 ± 4.65, 12 months; 89.50 ± 5.05 vs.75.81 ± 8.90, 24 months) significantly (p < 0.0001). Conclusions Minimally invasive CW is an optimal supplement for IMN in the treatment of femoral shaft fractures with displaced major fragments. As illustrated, benefits of CW might be promotion of bone union rate and improvement of functional outcome.
A new UHP unit in the Western Alps: First occurrence of coesite from the Monviso Massif (Italy)
Authors: Ghignone Stefano , Scaramuzzo Emanuele , Bruno Marco , Livio Franz A. 
Published: September 2022

AbstractThe Western Alps are one of the most studied exhumed subduction-accretionary complexes worldwide. Ultrahigh-pressure (UHP) metamorphism has been documented there since the 1980s. We now report the first discovery of coesite in the meta-ophiolitic suite of the Monviso Massif, corresponding to the fourth UHP unit defined on the Western Alps. Previous petrographic studies and results from thermodynamic modeling already suggested that these Alpine units may have experienced UHP metamorphism, but no occurrences of index minerals, such as coesite, have been reported to date. The newly discovered coesite inclusions from the Monviso Massif occur as intact single crystals (10–60 µm) hosted by garnet. The observations suggest that they have escaped re-equilibration and maintained all the original features from the trapping time. The reduced size of the crystals and the lack of re-equilibration significantly differ from the typical textural features described in past findings (i.e., radial cracks, palisade texture of quartz surrounding coesite relicts). Detailed garnet inclusions analysis and thermodynamic modeling constrained the metamorphic peak conditions at P = 2.8–2.9 GPa and T = 500–520 °C within the coesite stability field.The Lago Superiore Unit represents the fourth UHP unit discovered on the Western Alps. The UHP metamorphism on the Western Alps was considered rare due to the escape process of unusual units from mantle depths. In our view, the implication of our discovery provides new insight into UHP processes that seem to be more common than expected. Further tectonic reconstructions should take into account the common features observed in the UHP units to better constrain the subduction- and exhumation-related mechanisms that drove the actual stacking of mountain belts.
Method for automatic correction of offset drift in online sensors
Authors: Chowdhury Dhrubajit , Melin Alexander , Villez Kris 
Published: September 2022

Abstract
Successful operation and optimization of water treatment systems hinge on the availability of high-quality online sensor measurements. Ideally, the available measurements should be simultaneously accurate (i.e., unbiased and precise), representative, voluminous, and timely. This remains a pain-point in current water infrastructures, forming a barrier to a wider adoption of advanced and autonomous control systems. While short-lived symptoms, such as outliers and spikes, can be detected or corrected with state-of-the-art tools for fault detection and identification, it is much more difficult to detect, diagnose, and correct the symptoms of slow faults, such as changes in offset or sensitivity due to drift. The time scale of drift is often longer than the time scales of the system dynamics of interest. Moreover, sensor drift has been shown to occur at the same time and with similar rates when sensors are exposed to the same conditions. This challenges data quality management strategies based on redundancy. In this contribution, we develop a new method, including both a hands-off sensor calibration mechanism and an information-seeking control architecture that can handle the unique challenge of simultaneous and similar drift in online sensors.

Published: September 2022

AbstractThe aim of this study was to determine the water, sanitation, and hygiene conditions of schools in Antalya. This descriptive study was conducted with the administrators of 480 schools in 19 districts of Antalya. The data were collected with a questionnaire created by the researchers. In the study, number, percentage, and chi-square tests were used to evaluate the data. In 59% of the schools, a fountain in the garden or building was used as a source of drinking water, only 37.1% of the schools had a programmed pest control program, 32.1% of them had permanent cleaning personnel, and the cleaning materials were mostly (51.2%) obtained from their own budgets. While the number of sinks was sufficient according to the number of students in the schools, the number of toilets was not sufficient, especially for female students. It is of great importance that budget, material, and personnel deficits of schools, where the risk of infection transmission is high, are overcome by the authorities.

Abstract
The study proposed a practical approach for low impact development (LID) placement in dense residential urban catchments considering social, economic, and technical criteria. The objective is to shift the current technical orientation in LIDs' locating to a practical one with a specific level of residents' cooperation. Four stages were conducted, including (i) acquiring the residents' socio-economic information; (ii) hydraulic simulation of the stormwater collection system in the status quo, (iii) regionalization of the urban catchment using data mining, and (iv) proposing specific LIDs locating scenarios. The field study lasted around four months in a dense residential area with a combination of old/new buildings in the eastern Tehran metropolis. Regionalization was conducted by combining pre-processing/clustering techniques, resulting in six regions (preliminary results) and four regions after the clustering integration in the post-processing study. The regions have different priorities for the LIDs locating, including (i) cooperative cluster, 57 sub-catchments (SCs) and appropriate for rain barrel (RB) and green roof (GR) locating; (ii) semi-cooperative cluster, 12 SCs, appropriate for RB or GR locating; (iii) 15 SCs with infrastructural constraints in the third cluster and appropriate for RB; and (iv) non-cooperative cluster, 34 SCs, inappropriate for LIDs locating. Accordingly, seven locating scenarios were specified, and the developed EPA-SWMM model was modified to evaluate the scenarios for mitigating the study area's node flooding problems. The finding shows that the overflow volume reduced in a range of 36.7–93.1%, 28.3–78.7%, and 16.3–66.4% under the rainfall with 2, 5, and 10 years return periods, respectively.

Abstract: Education Quality Management Concept. This journal aims to provide an explanation of the concept of quality, school quality and the quality of educational institutions. This journal also focuses on the quality of education managed by professional institutions through integrated quality management. Educational institutions as producers of the service sector must pay attention to the quality, the quality of the managerial and academic aspects. Both of these aspects can be achieved through the application of the concept of total quality management (TQM). TQM is a management concept that places all university personnel (academics) as individuals who have responsibility for quality in accordance with their duties and functions. Quality of education is the degree of excellence in managing education effectively and efficiently to give birth to academic and extracurricular excellence in students who are declared to have passed for one level of education or completed a certain learning program. National Education Standards aim to ensure the quality of national education in the context of educating the nation's life and shaping the character and civilization of a dignified nation.
