Vision Positioning-Based Estimation Method and Its Simulation Studies on State of Underwater Manipulator

Work class remote operated vehicles (ROVs) are generally equipped with underwater manipulators and are widely used in underwater intervention and maintenance tasks. As the load of underwater operation is relatively heavy, most commercial underwater manipulators are hydraulically actuated and are not equipped with any sensor for joint angles to keep their architectures compact. Therefore, the automatic control methods widely used in industrial robots cannot be simply applied to underwater manipulators. In this paper, an estimation method on joint angles of manipulator is presented, in which several markers are arranged on the arm links and positioned from the corresponding cameras; consequently, the joint angles of the manipulator are estimated. The simulation results show that under typical optical vision positioning error (RMS: 5 mm), the positioning error of the end effector can be estimated as about 10 mm (RMS), which means that the proposed estimation method is feasible for the state estimation for automatic control of underwater manipulators.
Hierarchical round-robin mapper emulator for evaluating massively parallel Ethernet physical layer developing

: Future bandwidth-consuming services will require 10 Tbps class network interface. Massively parallel transmission with dynamic bandwidth assignment becomes a key. To realize the 10 Tbps class dynamic bandwidth ﬂexible media access control (MAC) mechanism, we have proposed “Dynamic MAC” concept. The key technical component is round-robin distribution of the MAC signal into parallel transmission lanes. Therefore, we have proposed a hierarchical round-robin mapper (HRRM) and developed a software-based dynamic MAC emulator for evaluating the HRRM. Details of the emulator and experiment results are presented.
Simple Fully Automatic Testing Method of Seepage Indices for Low-Permeability Materials

In anti-seepage engineering, quality control and engineering applications are based on the accurate measurement of seepage indices for low-permeability materials. The test used to determine the seepage indices for low-permeability materials adopts an external source to produce water pressure, and the seepage flux produced during the process requires manual measurement; thus, the apparatus used is complex and difficult to operate, thereby lowering the testing efficiency and restricting its application. In this study, a built-in servo motor was used to produce high water pressure with a pressure transmitter, and it controlled and measured the seepage pressure. According to the rotation number of the electric cylinder motor, the volume change of water in the hydraulic cylinder was calculated and, thus, the seepage flux was deduced. A simple fully automatic seepage apparatus for low-permeability materials was designed with a human–computer interface. The results showed the successful calculation of seepage flux as a function of the rotation number of the servo motor through automatic measurement. Furthermore, the replacement of the external high-pressure source with the built-in servo motor enhanced the safety performance, and the human–computer interface enabled an interactive operation and simplified the measurement structure. This simple testing method can provide technical support for quality inspection and construction control of anti-seepage engineering.
Use of Flash Continuous Glucose Monitoring Is Associated With A1C Reduction in People With Type 2 Diabetes Treated With Basal Insulin or Noninsulin Therapy

BACKGROUND Glycemic control is suboptimal in many individuals with type 2 diabetes. Although use of flash continuous glucose monitoring (CGM) has demonstrated A1C reductions in patients with type 2 diabetes treated with a multiple daily injection or insulin pump therapy regimen, the glycemic benefit of this technology in patients with type 2 diabetes using nonintensive treatment regimens has not been well studied. METHODS This retrospective, observational study used the IBM Explorys database to assess changes in A1C after flash CGM prescription in a large population with suboptimally controlled type 2 diabetes treated with nonintensive therapy. Inclusion criteria were diagnosis of type 2 diabetes, age <65 years, treatment with basal insulin or noninsulin therapy, naive to any CGM, baseline A1C ≥8%, and a prescription for the FreeStyle Libre flash CGM system during the period between October 2017 and February 2020. Patients served as their own control subject. RESULTS A total of 1,034 adults with type 2 diabetes (mean age 51.6 ± 9.2 years, 50.9% male, baseline A1C 10.1 ± 1.7%) were assessed. More patients received noninsulin treatments (n = 728) than basal insulin therapy (n = 306). We observed a significant reduction in A1C within the full cohort: from 10.1 ± 1.7 to 8.6 ± 1.8%; Δ −1.5 ± 2.2% (P <0.001). The largest reductions were seen in patients with a baseline A1C ≥12.0% (n = 181, A1C reduction −3.7%, P <0.001). Significant reductions were seen in both treatment groups (basal insulin −1.1%, noninsulin −1.6%, both P <0.001). CONCLUSION Prescription of the flash CGM system was associated with significant reductions in A1C in patients with type 2 diabetes treated with basal insulin or noninsulin therapy. These findings provide evidence for expanding access to flash CGM within the broader population of people with type 2 diabetes.
A Two‐Phase Model for the Evolution of Planetary Embryos With Implications for the Formation of Mars

Attempts to constrain the accretion history of Mars using geochemical observations have focused on the chronology of core formation. However, given the possibility of incomplete metal‐silicate equilibration, most previous results cannot distinguish between the following two scenarios: (1) Mars was formed early through gradual accretion and remained isolated as a “planetary embryo” and (2) Mars underwent relatively protracted accretion involving collisions between planetary embryos. Here we use a two‐phase model to demonstrate that, despite strong heating from the short‐lived radionuclide 26Al, the mantle of a Mars‐sized planetary embryo may stay effectively solid because the generation and migration of melts in relatively small fractions leads to efficient heat transport. In this scenario, the effectively solid mantle would have undergone substantial differentiation before the extinction of 26Al, and the disparate planetary building blocks would not have been homogenized within the embryo. Hence, features of very early silicate differentiation (within the first few million years of the solar system) and significant nucleosynthetic isotope heterogeneity would be expected to exist in stranded planetary embryos. In contrast, meteorite observations suggest that the crust‐mantle system of Mars is homogeneous in nucleosynthetic isotope anomalies and the onset of silicate differentiation was no earlier than ∼15 Myr after solar system formation. This discrepancy implies that Mars is not a stranded planetary embryo. Instead, we suggest that the accretion of Mars involved at least one collision between planetary embryos with comparable sizes that caused complete melting and homogenization during the giant‐impact stage of planetary growth.
Chemo-biocatalytic one-pot two-step conversion of cyclic amine to lactam using whole cell monoamine oxidase

BACKGROUND Most biocatalysts currently involved in one-pot chemoenzymatic cascades are pure enzymes, while whole cells and crude enzyme extracts remain unexplored. This work aims to develop a chemo-biocatalytic one-pot two-step system involving whole cell monoamine oxidase (MAO, EC 1.4.3.4) coupled with a Cu-based oxidative system (CuI/H2O2) for the transformation of 1,2,3,4-tetrahydroisoquinoline (THIQ) to 3,4-dihydroisoquinolin-1(2H)-one (DHIO). RESULTS MAO-N variants D9 and D11 were tested as whole cell and crude lysate biocatalysts for biological oxidation. Whole Escherichia coli OverExpress C43(DE3) cells expressing MAO-N D9 showed the best performance (Vmax = 36.58 mmol L−1 h−1, KM = 8.124 mmol L−1, maximum specific productivity 89.3 μmol min−1 g−1DCW) and were employed in combination with CuI/H2O2 in a sequential one-pot two-step process. The biotransformation was scaled-up to the initial volume of 25 mL and after triple THIQ feeding, 48.2 mmol L−1 of the intermediate 3,4-dihydroisoquinoline (DHIQ) was obtained with a yield of 71.3%. Afterwards, chemical catalysts (1 mol% CuI and 10 eq. H2O2) were added to the biologically produced DHIQ, which was transformed to ∼30 mmol L−1 DHIO at 69.4% overall yield. CONCLUSION As MAO-N variants have wide substrate specificity, this work broadens the portfolio of one-pot chemoenzymatic processes employing whole cell biocatalysts, representing an alternative to using pure enzymes. © 2016 Society of Chemical Industry
I Read It Online: Understanding How Undergraduate Students Assess the Accuracy of Online Sources of Health Information

Online sources of health information are a significant means by which the public educates itself about health and wellness. The purpose of this study is to investigate how undergraduate students evaluate and assess health-related websites for accuracy, as well as the self-reported factors used in identifying whether a website is an accurate source of information. One hundred and fifty-seven students participated by reviewing a series of 10 health-related websites and indicated whether they believed the website to be an accurate source of health information. Students completed an open-ended question to self-report how they made this determination. Results indicate that students were not able to accurately distinguish between credible sources of web-based health information and those sources that were previously categorized as not being credible sources. Analysis of self-reported qualitative feedback gave rise to 6 factors used to determine the accuracy of the websites reviewed. While students report using these factors, and these factors are consistent with previous research, this does not appear then to be translating to successful determination of a source’s accuracy. Educating students in proper fact-checking and evaluation skills may be warranted to develop a generation of individuals who can be said to have better health literacy.
An organocatalytic enantioselective ring-reorganization domino sequence of methyleneindolinones with 2-aminomalonates

An organocatalytic enantioselective ring-reorganization domino sequence (Michael addition/intramolecular ring-opening/lactamization) of methyleneindolinones with 2-aminomalonates has been established in this work. As a result, pyrrolo[3,4-c]quinolinones bearing two to three contiguous chiral centers were efficiently assembled in high yields (up to 92%) with excellent diastereoselectivities (>20 : 1 dr) and enantioselectivities (up to >99% ee).
The puzzling nuanced status of who free relative clauses in English: a follow-up to Patterson and Caponigro (2015)

This squib challenges Patterson & Caponigro's (2015, this journal) claim that there are few acceptable free relative clauses with who. We show that free relatives with who are generally acceptable when they are ‘transparent’ free relatives or complements of a copula, and add further nuance to their findings concerning how the degree of acceptability of free relatives with who varies according to positional factors.
Precoding Aided Data Correlation Scheme for Channel Estimation Technique in MIMO-OFDM System

Channel estimation is considered as an important phase in Multiple Input Multiple Output – Orthogonal Frequency Division Multiplexing (MIMO-OFDM) networks which can enhances the performance significantly. Channel estimation widely classified as pilot based, blind and semi-blind channel estimation. The pilot-based channel estimation decreases the data transmission rate and spectral efficiency. To overcome these issues of existing schemes, we present a novel blind channel estimation technique. According to proposed scheme, we transmit the data in a block-wise manner. The proposed scheme uses precoding technique to establish the correlation between these blocks. Further, we use channel correlation to solve the diagonal uncertainty of correlation matrix which helps to improve the system performance. We present a comparative analysis study which shows that proposed approach can achieve better performance in terms of Normalized Mean Square Error (NMSE) and Mean Square Error (MSE) when compared with existing techniques.
Governmentality without Truth: An Essay on the Role of Foucauldian Thinking in a Post- Truth Society

Considering the issue of power in Foucault will always lead to comments on the issue of knowledge and vice versa. What I suggest in this paper, however, is to look into both topics presented in the work by Foucault separately, at least to a certain extent. I believe that the evolution of these two threads in his works allows us to evaluate their suitability differently as far as their relevance to contemporary culture is concerned. Foucault’s approach to the issue of power and its evolution towards so-called governmentality is evidence of how accurately he sensed the direction of changes to the Zeitgeist of Western civilizations, a fact which cannot be said about the evolution of Foucault’s approach to the issue of knowledge, leaning towards the question of truth and truth-telling. The aim of this paper is to substantiate the outlined and differentiated evaluation of Foucault’s oeuvre while, at the same time, highlighting the predominant features of contemporary culture. Special attention will be paid to the role of sociology in governmentality.
Dynamic design method of digital twin process model driven by knowledge-evolution machining features

Machining plan is the core of guiding manufacturing production and is regarded as one of the keys to ensure the quality of product processing. Existing process design methods are inefficient to quickly handle the machining plan changed induced by the unpredictable events in real-time production. It inevitably causes time and economic losses for the enterprise. In order to express the evolutionary characteristics of product processing, the construction method of digital twin process model (DTPM) is proposed based on the knowledge-evolution machining features. Three key technologies include correlation structure of process knowledge, expression method of the evolution geometric features and the association mechanism between two are solved. On this basis, the construction framework of DTPM is illustrated. Then, the organisation and management mechanism of multi-source heterogeneous data is discussed in detail. At last, a case study of the complex machined part is researched, the results show that the processing time reduced by about 7% and the processing stability improved by 40%. Meanwhile, the implementation scheme, application process and effect of this case are described in detail to provide reference for enterprises.
Domestic dogs and water-availability effects on non-volant mammals in a protected area, south-eastern Brazil

Abstract Context. Urbanisation and human population growth can generate conflicts, threatening biodiversity. Resource availability and vegetation complexity owing to human influence may increase the potential that a habitat would lose its species. Conservation biology aims to understand how to soften human influence and maintain viable in situ populations. Aims. We evaluated the non-volant mammal’s richness and abundance in an Atlantic Forest protected area. Specifically, we tested (1) the effect of distance from water resource and vegetation (canopy and understorey cover) on richness and abundance and (2) the effects of anthropogenic pressure such as domestic dog abundance, distances from human settlements, and from the road on the community of non-volant mammals. Methods. We collected the data from January through December of 2017 in 20 sampling sites by using live traps (for small mammals), active search, sand plots and camera traps. Key results. We recorded 22 species of non-volant mammals, among them four endemic, two endangered and two invasive exotic species. The main covariates that affected the structure and composition of the non-volant mammal’s assemblage was the domestic dog abundance, which repels most of the species into the forest and water resources, which attract the species to forest edges. Conclusions. Our results indicated that the negative impact of domestic dog presence in the non-volant mammal’s community is so evident that it could generate changes in the composition, richness, and local distribution of the species. Implications. We suggest that management action in this protected area must initiate a control of domestic dogs to minimise their impact.
What is the Impact of Physical Activities in Home Isolation on Residents’ Well-Being: A Cross-Sectional Survey During the COVID-19 Social Quarantine

Background: During isolation, physical activity can enhance residents’ well-being. The objective of the present study was to examine the associations between residents’ physical activity, health values, and well-being during isolation.Methods: Based on the physical activity rating scale, health values scale, subjective well-being scale, and the satisfaction with life scale, 505 valid questionnaires were collected online from 31 provinces, municipalities and autonomous regions in China. A series of multiple linear regression models were established to study the relationship between variables, and the bootstrap confidence interval was selected to test the mediating effect.Results: The results showed that during the period of isolation, physical activity directly(b =0.463, p < 0.001) or indirectly(b =0.358, p < 0.001) had a positive impact on residents’ well-being through the mediating effect of health values. There is a positive correlation between physical activity and health values(b =0.710, p < 0.001), while health values had a direct positive impact on well-being(b =0.504, p < 0.001). In addition, moderate amount of physical activity is more likely to improve the well-being of residents during home isolation compared to small and large amount of physical activity.Conclusions: Moderate exercise at home and regular physical activity are beneficial to our physical and mental health, especially to improve the overall well-being. At the same time, it is necessary for the World Health Organization and governments at all levels to strengthen the guidance and publicity of health values, so as to eliminate the impact of COVID-19 on people to a greater extent.
Repetitions in Reserve Is a Reliable Tool for Prescribing Resistance Training Load

Abstract Lovegrove, S, Hughes, L, Mansfield, S, Read, P, Price, P, and Patterson, SD. Repetitions in reserve is a reliable tool for prescribing resistance training load. J Strength Cond Res 36(10): 2696–2700, 2022—This study investigated the reliability of repetitions in reserve (RIR) as a method for prescribing resistance training load for the deadlift and bench press exercises. Fifteen novice trained men (age: 17.3 ± 0.9 years, height: 176.0 ± 8.8 cm, body mass: 71.3 ± 10.7 kg) were assessed for 1 repetition maximum (1RM) for deadlift (118.1 ± 27.3 kg) and bench press (58.2 ± 18.6 kg). Subsequently, they completed 3 identical sessions (one familiarization session and 2 testing sessions) comprising sets of 3, 5, and 8 repetitions. For each repetition scheme, the load was progressively increased in successive sets until subjects felt they reached 1-RIR at the end of the set. Test-retest reliability of load prescription between the 2 testing sessions was determined using intraclass correlation coefficient (ICC) and coefficient of variation (CV). A 2-way analysis of variance with repeated measures was used for each exercise to assess differences in the load corresponding to 1-RIR within each repetition scheme. All test-retest comparisons demonstrated a high level of reliability (deadlift: ICC = 0.95–0.99, CV = 2.7–5.7% and bench press: ICC = 0.97–0.99, CV = 3.8–6.2%). Although there were no differences between time points, there was a difference for load corresponding to 1-RIR across the 3 repetition schemes (deadlift: 88.2, 84.3, and 79.2% 1RM; bench press: 93.0, 87.3, and 79.6% 1RM for the 3-, 5-, and 8-repetition sets, respectively). These results suggest that RIR is a reliable tool for load prescription in a young novice population. Furthermore, the between-repetition scheme differences highlight that practitioners can effectively manipulate load and volume (repetitions in a set) throughout a training program to target specific resistance training adaptations.
Numerical investigation on the electronic components' cooling for different coolants by finite element method

In this study, we conducted a numerical simulation to examine the cooling performance of an aluminum finned heat sink attached to a silicon chip, placed in a chamber of a rectangular cross‐section. The heat sink is cooled by convective heat transfer utilizing nine commercially available gaseous coolants, namely air, hydrogen, helium, nitrogen, oxygen, carbon dioxide, freon12 vapor, propane, and ammonia. To select an appropriate coolant for electronic devices in terms of thermal–hydraulic performance, the maximum temperature on the chip domain and the associated pressure drop in the cooling channel as a function of coolant velocity are analyzed for the aforementioned fluids. It has been found that the minimum temperature is recorded for propane and freon12 vapor, which is approximately 31.1°C, for a coolant velocity of 0.5 m/s, but freon12 vapor shows the highest pressure drop, approximately 900 mPa, among all coolants. In the overall velocity regime, hydrogen shows the best cooling performance in terms of both cooling capacity and hydrodynamic characteristics. But considering safety issues, helium can be a better alternative. This comprehensive study provides a better understanding of different coolant performances, which will aid engineers to develop an effective cooling technique to accommodate the inexorably rising power demand.
Cognitive Component Analysis Comparing Three Chinese Remote Associates Tests: Linear Logistic Latent Trait Model Approach

ABSTRACT The Remote Associates Test, generally used in creativity research, has Chinese versions for the three levels of “radical-word-vocabulary. ” However, research has not been conducted on the influence of the item components on the difficulties among these Chinese Remote Associates Tests (CRATs). The present study selected six item components from the construction rules for three versions of CRATs, collected 555 participants’ responses to them, and analyzed the differences and similarities in the predictions of item difficulty among the six item components. The results show that item difficulty decreased if the targets are high-frequency or the stimuli are low-frequency words, but item difficulty increases if the stimulus can connect to more words, while the concreteness of the target does not significantly predict item difficulty. Moreover, the concreteness of the stimulus negatively predicts the difficulty of the CRRAT but positively predicts the difficulty of the CCRAT High association transfer increased the difficulty of the CWRAT but had no influence on the other two versions of CRAT. Therefore, these findings indicate the different influences of item components on item difficulty, strengthen the structural validity of the test, and also provide a reference for test development of the CRAT.
