Influence of Surfacing Fe-Based Alloy Layers on Wire Arc Additive Manufactured Ni-Based Superalloys Material on Its Microstructure and Wear Properties

Wire arc additively manufactured (WAAM) Ni-based materials have good properties but are costly and hard to cut, leading to difficulties in machining after welding and wasting the materials. To overcome these shortcomings, this work proposes a method of surfacing Fe-based alloy layers on WAAM Ni-based material. The effect of this method on the microstructure and wear properties of WAAM Ni-based materials is discussed. In this work, a Fe-based alloy (JX103) was welded as the last layers of the WAAM Ni-based superalloy (JX201) material. The hardness, microstructure, and wear behavior of the material with different residual Fe-based materials were tested and analyzed. Our results indicate that the surface hardness was smoothly increased from HV350 to HV400 by overlaying Fe-based alloy layers. Microstructure analysis shows that γ-Fe gradually disappears, and the carbide form changes from WAAM Ni-based superalloys to Fe-based alloys. In the fusion boundary, the occurrence of cellular dendritic growth, a type -Ⅱ boundary, and low dilution indicate good crack resistance and good connection performance between these two materials. The wear test showed that the wear resistance of JX201 was decreased by changing the last layer to JX103. However, as the residual thickness of JX103 decreased, the influence gradually reduced. Meanwhile, the wear mechanism changed from severe abrasive and adhesive wear to light abrasive wear. When the thickness is less than 0.5 mm, the wear weight per minute is at the same level as the sample without JX103.
Simulation-Based Outreach Program Improves Rural Hospitals’ Team Confidence in Neonatal Resuscitation

Introduction: Neonatal resuscitation is a high acuity, low occurrence event (HALO), and in rural community hospitals, low birth rates prevent providers from regular opportunities to maintain essential resuscitation skills. Simulation is an effective training modality for medical education, although resources for simulation are often limited in rural hospitals. Our primary objective was to test the hypothesis that in situ neonatal resuscitation simulation training improves rural hospitals' delivery room team confidence in performing key Neonatal Resuscitation Program® (NRP®) skills. Our secondary objective was to compare confidence to performance as measured by adherence to NRP® guidelines. Methods: We conducted a quasi-experimental pre-training survey and post-training survey of delivery room team confidence in NRP® skills at five level one delivery hospitals before and after an in situ simulation training program. Participants included rural hospitals’ usual delivery room team members. Participants rated their confidence on a five-point Likert scale. Simulations were analyzed using an adapted version of a validated scoring tool for NRP® adherence and presented as overall percentage scores. Results: Our data demonstrate a significant improvement in self-assessed confidence levels pre- and post-simulation training in key areas of neonatal resuscitation. Participants reported higher confidence in airway management (4 vs. 3, p=0.003), emergency intravenous access (3 vs. 2, p=0.007), and the ability to manage a code in the delivery room (4 vs. 3, p=0.013) and the operating room (4 vs. 3, p=0.028). Improvements were also noted in their team member’s knowledge and skills to perform neonatal resuscitation. While improvements were appreciated in confidence, the performance of skills (NRP® adherence scores) was often in the sub-optimal performance range. Conclusions: An in situ-based neonatal resuscitation outreach simulation program improves self-confidence among rural delivery room teams. Additional research is needed to understand how to translate improved confidence into actual improved performance.
Computation with Unitaries and One Pure Qubit

We define a semantic complexity class based on the model of quantum computing with just one pure qubit (as introduced by Knill and Laflamme) and discuss its computational power in terms of the problem of estimating the trace of a large unitary matrix. We show that this problem is complete for the complexity class, and derive some further fundamental features of the class. We conclude with a discussion of some associated open conjectures and new oracle separations between classes.
Beltrami structures in disk-jet system: alignment of flow and generalized vorticity

The combination of a thin disk and a narrowly-collimated jet is a typical structure that is observed in the vicinity of a massive object such as AGN, black hole or YSO. Despite a large variety of their scales and possible diversity of involved processes, a simple and universal principle dictates the geometric similarity of the structure; we show that the singularity at the origin ($r=0$) of the Keplerian rotation ($V_\theta \propto r^{-1/2}$) is the determinant of the structure. The collimation of jet is the consequence of the alignment ---so-called Beltrami condition--- of the flow velocity and the "generalized vorticity" that appears as an axle penetrating the disk (the vorticity is generalized to combine with magnetic field as well as to subtract the friction force causing the accretion). Typical distributions of the density and flow velocity are delineated by a similarity solution of the simplified version of the model.
|Z_{Kup}|=|Z_{Henn}|^2 for Lens spaces

M. Hennings and G. Kuperberg defined quantum invariants Z_{Henn} and Z_{Kup} of closed oriented 3-manifolds based on certain Hopf algebras, respectively. We prove that |Z_{Kup}|=|Z_{Henn}|^2 for lens spaces when both invariants are based on factorizable finite dimensional ribbon Hopf algebras.
Input-to-State Stability Analysis of Digital Filters With Generalized Overflow Arithmetic and Time-Varying Delay

This work focuses on the input-to-state stability (ISS) of digital filters with disturbances and time-varying delay in the presence of generalized overflow arithmetic. First, an extra-freedom-based lemma is derived to consider the information about the overflow arithmetic connecting the digital filter's state. Then, a novel delay-dependent ISS criterion of the digital filter is established based on the given lemma, which has less conservatism than the criterion described in the existing results. At last, the feasibility and advantages of the presented ISS analysis methods are demonstrated using a numerical simulation.
Outcomes of Catheter-Delivered Thrombolytic Therapy and Resuscitative Measures in a Cardiac Arrest Patient With Massive Pulmonary Embolism: A Case Report

Acute massive pulmonary embolism is the most critical presentation of venous thromboembolism that needs early detection and management for a better outcome. We present the case of a 42-year-old female who presented to the emergency department (ED) complaining of acute dyspnea and descended into cardiac arrest. Working through the advanced cardiac life support guidelines and appropriate resuscitative measures, having high clinical suspicion supported by bedside ultrasound findings, massive pulmonary embolism was the most likely diagnosis, and so the patient was treated with thrombolytic therapy delivered via a central venous catheter. Return of spontaneous circulation was achieved, and consequently, she made a complete recovery with no adverse neurological or hemodynamic sequelae. The aim of presenting this topic is to review the literature available on approaches to thrombolytic doses in life-threatening cases of massive pulmonary embolism and to add to an already ongoing discussion about the effects and outcomes of various dosing regimens. The above facts will lead us to conclude that any discussion seeks to remind us of the primary management principle. All physicians should bear this in mind while managing any case ("primum non-nocere," which is a Latin phrase that means "first, do no harm"); it helps to fuel ideologies to seek best practice interventions that ensure the best outcome for pulmonary embolism patients. And such experiences are worth sharing with the world.
ERS technical standards for using type III devices (limited channel studies) in the diagnosis of sleep disordered breathing in adults and children

For more than three decades, type III devices have been used in the diagnosis of sleep disordered breathing in supervised as well as unsupervised settings. They have satisfactory positive and negative predictive values for detecting obstructive and central sleep apnoea in populations with moderately high pre-test probability of symptoms associated with these events. However, standardisation of commercially available type III devices has never been undertaken and the technical specifications can vary widely. None have been subjected to the same rigorous processes as most other diagnostic modalities in the medical field. Although type III devices do not include acquisition of electroencephalographic signals overnight, the minimum number of physical sensors required to allow for respiratory event scoring using standards outlined by the American Academy of Sleep Medicine remains debatable. This technical standard summarises data on type III studies published since 2007 from multiple perspectives in both adult and paediatric sleep practice. Most importantly, it aims to provide a framework for considering current type III device limitations in the diagnosis of sleep disordered breathing while raising research- and practice-related questions aimed at improving our use of these devices in the present and future.

Preoperative EUS staging of esophageal carcinoma

Background. EUS is an essential tool in the evaluation of patients with esophageal cancer allowing accurate staging and permitting stratified treatment options. Aim. We studied prospectively the impact of EUS in the evaluation and decision for therapy of patients with esophageal cancer. Material and methods. From March 2001 through March 2006, 220 patients were hospitalized at the Center of Gastroenterology and Hepatology, Fundeni Clinical Institute, with the diagnosis of esophageal cancer. Out of the 220, 41 patients, with no major comorbidities and already screened by abdominal and thoracic CT to disclose distant metastases, had EUS with the definite purpose of staging esophageal carcinoma and selecting adequate therapy. Assuming that without preoperative staging by EUS, all 41 patients in the study group would have been offered surgical treatment, we evaluated the number of patients and the modality in which EUS resulted in changes to the therapeutic plan. Statistical analysis: Fisher’s exact test. Results. Depth of invasion was recorded for the 41 patients as follows: T1 in 2 patients (4.9%), T2 in 6 patients (14.6%), T3 in 24 patients (58.5%), and T4 in 10 patients (22%). Regional lymph node (N) status was as follows: N0 in 7 patients (17%) and N1 in 34 patients (83%). Assessment of distant metastases (M) was recorded showing 4 patients with celiac axis lymph nodes metastases (M1). Preoperative EUS staging changed the decision for surgery in 18 of 41 patients (44%) (p<0.0001) and allowed primary esophagectomy in only 6 patients (15%) (p<0.0001). Compared to histopathology, the overall accuracy of EUS staging for pT1 and pT2 was 80%, for staging pT3 and pT4 77% and for lymph node evaluation was approximately 75%. Conclusion. Esophageal EUS offers useful information to clinicians caring for patients with esophageal cancer, impacts clinical decision making, and should be used in appropriate settings to plan patients’ care.
Serum Untargeted UHPLC-HRMS-Based Lipidomics to Discover the Potential Biomarker of Colorectal Advanced Adenoma

Background: As a key precancerous lesion, colorectal advanced adenoma (CAA) is closely related to the occurrence and development of colorectal cancer (CRC). Effective identification of CAA-related biomarkers can prevent CRC morbidity and mortality. Lipids, as an important endogenous substance, have been proved to be involved in the occurrence and development of CRC. Lipidomics is an advanced technique that studies lipid metabolism and biomarkers of diseases. However, there are no lipidomics studies based on large serum samples to explore diagnostic biomarkers for CAA. Methods: An integrated serum lipid profile from 50 normal (NR) and 46 CAA subjects was performed using ultra-high performance liquid chromatography tandem high-resolution mass spectrometry (UHPLC-HRMS). Lipidomic data were acquired for negative and positive ionization modes, respectively. Differential lipids were selected by univariate and multivariate statistics analyses. A receiver operator characteristic curve (ROC) analysis was conducted to evaluate the diagnostic performance of differential lipids. Results: A total of 53 differential lipids were obtained by combining univariate and multivariate statistical analyses ( P < 0.05 and VIP > 1). In addition, 12 differential lipids showed good diagnostic performance (AUC > 0.90) for the discrimination of NR and CAA by receiver operating characteristic curve (ROC) analysis. Of them, the performance of PC 44:5 and PC 35:6e presented the outstanding performance (AUC = 1.00, (95% CI, 1.00– 1.00)). Moreover, triglyceride (TAG) had the highest proportion (37.74%) as the major dysregulated lipids in the CAA. Conclusion: This is the first study that profiled serum lipidomics and explored lipid biomarkers with good diagnostic ability of CAA to contribute to the early prevention of CRC. Twelve differential lipids that effectively discriminate between NR and CAA serve as the potential diagnostic markers of CAA. An obvious perturbation of TAG metabolism could be involved in the CAA formation.

EXPLORING THE IMPACT OF DECENTRALIZED AUTONOMOUS SUPPLY CHAINS (DASCs) IN THE AGRICULTURAL SECTOR: AN INNOVATION ASSIMILATION PERSPECTIVE

Blockchain, distributed ledger technology (DLT) and smart-contract technology enhance the effectiveness and automation of business processes along supply chains. The rising interest in the development of decentralized autonomous organizations (DAO) shows that blockchain and related decentralized technologies have the potential to reform how businesses conduct their supply chain operations. A DAO is an organization wherein business rules are encoded in smart-contract programs that are executed automatically when specified rules are met. There is a scarcity of research that has examined the impact of blockchain technologies in facilitating decentralized autonomous supply chains in the agricultural sector. Therefore, the purpose of this paper is twofold. First, we introduce a new concept to the blockchain literature called decentralized autonomous supply chains (DASCs) and discuss how this new concept can overcome the challenges associated with extant centralized agricultural supply chains. Finally, we also propose a framework that can explore how the concept of DASCs assimilates into agricultural supply chains to assist organizations with the realization of benefits not originally conceived with blockchain technologies.
A study of Creativity in Relation to Achievement Motivation of IX Standard Students of CBSE Schools in Aurangabad City

Adolescence is one of the crucial stage of development between childhood and adulthood moments, in which many physical, cognitive, social and emotional changes takes place. Psychologist and educationist in their studies have found that after the early childhood adolescence is the most creative age. The functioning of creativity of adolescence is superior to the child’s creativity, because it is more rational, responsible, productive and independent while the child’s creativity is instinctual. Therefore it is significant to study what happens to the potential creative force of children when they grow to adolescence and why this potential force not contribute due to the individual, family and the society. It is said that Achievement Motivation is the motivational variable of functional creativity. In this study an attempt is made to find the relationship between creativity and Achievement Motivation. The study is performed on 300 IX standard students of CBSE schools of Aurangabad city. The result revealed that there is positive but low and substantial relationship between Creativity and Achievement Motivation. Result also revealed that there is no significant difference between Creativityand Achievement Motivation of Male and Female IX standard students of CBSE schools of Aurangabad city, whereas Creativity of IX standard students of CBSE schools of Aurangabad city is moderate and Achievement Motivation is high.
DMSO_A_370118 2675..2682

Background: It is uncertain whether the effect of hyperglycemia on mortality among patients with acute coronary syndrome (ACS) could be adjusted by other modifiable risk factors. Greater body mass index (BMI) might enhance the effect of fasting blood glucose (FPG) on cardiovascular mortality in patients with ACS. Methods: We retrospectively enrolled patients admitted for ACS from 2008 to 2017 in Beijing and divided them into three BMI groups (normal weight ≤ 25 kg/m, overweight 25–29.9 kg/m, obese ≥ 30 kg/m). The relationships between the blood glucose levels and all-cause or cardiovascular mortalities and their heterogeneities across the groups were analyzed using Cox regression models. Results: A total of 8,086 patients were enrolled, with 746 all-cause and 496 cardiovascular mortalities recorded during the follow-up period. Each 1 mmol/L increase in FPG was associated with an increased risk of all-cause mortality across all groups (adjusted hazard ratio [HR] 1.06, 95% confidence interval [CI] 1.02–1.09 for normal weight patients; adjusted HR: 1.09, 95% CI: 1.05–1.13 for overweight patients; adjusted HR: 1.12, 95% CI: 1.03–1.22 for obese patients), and was associated with an increased risk of cardiovascular mortality among overweight (adjusted HR: 1.10, 95% CI: 1.05–1.14) and obese patients (adjusted HR: 1.15, 95% CI: 1.04–1.26), which was greater (p for heterogeneity = 0.006) than the association in the normal weight group (adjusted HR: 1.03, 95% CI: 0.99–1.08). Similar results were found among 2,537 patients with ACS diagnosed with diabetes. Conclusion: Greater BMI enhances the effect of FPG on cardiovascular mortality among patients with ACS.
IMPACT OF E-MAINTENANCE AND ARTIFICIAL INTELLIGENCE TOOLS ON COSTS AND BENEFITS

In the current era, the market has extremely get developed, and the introduction of new technologies, and digitalization, AI… becomes a must. Indeed, only a few companies could be competitive nowadays in a digitized environment. This said, most companies today have introduced digitalization to all their strategic processes including maintenance as it’s considered as one of the development levers of many businesses since it has a direct impact on many key indicators i.e: costs, reliability, availability, safety, and productivity. Polemics about digitized maintenance have begun between the last decade of the previous century and the early 2000, it is commonly named “e-maintenance”. So far there is no standardized definition of the concept given by an official institution. Otherwise, as just a little attention was given to this subject in literature, this paper was written to give a global image of the impact of e-maintenance on costs and profit.
Probing neutrino mixing angles with ultrahigh energy neutrino telescopes

We point out that detecting $\nuebar$'s from distant astrophysical sources with the up-coming and future neutrino telescopes using the Glashow resonance channel $\nuebar e^{-}\to W^{-} \to$ anything, which occurs over a small energy window around the $\nuebar$ energy of $\sim6.3\pev$, offers a new way of measuring or setting limits on neutrino mixing angles, in particular the angle $\theta_{12}$, thereby providing an independent experimental probe of neutrino mixing angles. We also discuss how this exercise may throw light on the nature of the neutrino production mechanism in individual astrophysical sources.
Multi-Party Private Function Evaluation for RAM

Private function evaluation (PFE) is a special type of MPC protocols that, in addition to the input privacy, can preserve the function privacy. In this work, we propose a PFE scheme for RAM. In particular, we first design an efficient 4-server distributed ORAM scheme with amortized communication <inline-formula> <tex-math notation="LaTeX">$O(\log n)$ </tex-math></inline-formula> per access (both reading and writing). We then simulate a RISC RAM machine over the MPC platform, hiding (i) the memory access pattern, (ii) the machine state (including registers, program counter, condition flag, etc.), and (iii) the executed instructions. Our scheme can naturally support a simplified TinyRAM instruction set; if a public RAM program <inline-formula> <tex-math notation="LaTeX">$P$ </tex-math></inline-formula> with given inputs <inline-formula> <tex-math notation="LaTeX">$x$ </tex-math></inline-formula> needs to execute <inline-formula> <tex-math notation="LaTeX">$z$ </tex-math></inline-formula> instruction cycles, our PFE scheme is able to securely evaluate <inline-formula> <tex-math notation="LaTeX">$P(x)$ </tex-math></inline-formula> on private <inline-formula> <tex-math notation="LaTeX">$P$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$x$ </tex-math></inline-formula> within <inline-formula> <tex-math notation="LaTeX">$5z+1$ </tex-math></inline-formula> online rounds. We prototype and benchmark our system for set intersection, binary search, and quicksort algorithms. For instance, obliviously performing the binary search algorithm on a 210 array takes <inline-formula> <tex-math notation="LaTeX">$5.81s$ </tex-math></inline-formula> with function privacy.
Automated Detection and Quantification of Brain Tumors in MRI Scans through Lab VIEW Employing Morphological Technique

- In this paper the authors present the development of an algorithm based on the Morphological Technique for Automatic Detection of Brain Tumors in MR Images of the Brain and their Quantification. The basic morphological transformations identify the shape of the region of interest in a binary image based on distinct changes in spatial intensity levels in the tumor region in the image. This is implemented through Vision Assistant tool box in Lab VIEW 12. The developed algorithm is tested on a Ground Truth Image which could detect and quantify the Tumor parameters thus validating its accuracy and reliability. The algorithm is able to automatically detect and quantify the morphological parameters like the maximum width, maximum length and Areas of the Tumors and Brain in these images. The results of the measurements obtained through this algorithm are in good agreement within ± 3% error with those of Ground Truth images. Hence, then implemented the same on a set of MR Images of 12 different patients for the measurements of maximum width, maximum length and the areas of the Tumor and the Brain.
