Development of a Combined Orchard Harvesting Robot Navigation System

Our research concerned the development of an autonomous robotic navigation system for orchard harvesting with a dual master-slave mode, the autonomous navigation tractor orchard transport robot being the master followed by a navigation orchard picking robot as the slave. This addresses the problem that in single master-slave navigation mode, agricultural combined harvesting equipment cannot stop repeatedly between rows of apple trees and drive continuously when turning. According to distances obtained from a global positioning system (GNSS), ground points were used to switch the navigation mode of the transport and picking robot. A cloth simulation filter (CSF) and random sample consensus (RANSAC) algorithm was used to obtain inter-row waypoints. The GNSS point was manually selected as the turn waypoint of the master and a kinematic model was used to compute the turn waypoints of the slave. Finally, we used a pure pursuit algorithm to track these waypoints sequentially to achieve master-slave navigation and ground head master-slave command navigation. The experimental results show that the data packet loss rate was less than 1.2% when the robot communicated in the orchard row within 50 m which meets the robot orchard communication requirements. The master-slave robot can achieve repeated stops in the row using follow navigation, which meets the demands of joint orchard harvesting. The maximum, minimum, mean and standard deviation of position deviation of the master robot were 5.3 cm, 0.8 cm, 2.4 cm, and 0.9 cm, respectively. The position deviations of the slave robot were larger than those of the master robot, with maximum, minimum, mean and standard deviation of 39.7 cm, 1.1 cm, 4.1 cm, and 5.6 cm, respectively. The maximum, minimum, mean and standard deviation of the following error between the master-slave robot were 4.4 cm, 0 cm, 1.3 cm, and 1 cm respectively. Concerning the ground head turn, the command navigation method allowed continuous turning, but the lateral deviation between robots was more than 0.3 m and less than 1 m, and the heading deviation was more than 10° and less than 90°.

Structural Variation Detection of Adolescent Thyroid Cancer Using Optical Mapping

Structural variation (SV) is a fundamental genetic cause for cancer, with demonstrated correlation to disease progression and treatment response. Traditional sequencing method cannot provide full genomic landscape especially large-scale and complex structural variation. To overcome these limitations, we adopted a combined sequencing approaches, including optical mapping, single molecular sequencing and short reads shotgun sequencing, to evaluate the SV in thyroid cancer. Different numbers, length and types of structural variation, with genes affected by SV were scrutinized. Integrating these results could showed comprehensive scenario for thyroid cancer in a genomic view. We demonstrate that integrated approaches could provide a powerful tool for capturing a higher level of genomic SV, creating new interpretation of sequencing data of particular relevance to human cancer.
Flexibility in Faculty Work-Life Policies at Medical Schools in the Big Ten Conference: A Ten-Year Follow-up Study

Background: Flexible work-life policies for medical school faculty are necessary to support career progress, advancement, retention, and job satisfaction. Objective: Our objective was to perform a 10-year follow-up descriptive assessment of the availability of flexible work-life policies for faculty in medical schools in the Big Ten Conference. Design: In this descriptive study, a modified objective scoring system was used to evaluate the flexibility of faculty work-life policies at 13 medical schools in the Big Ten Conference. Policy information was obtained from institutional websites and verified with the human resources offices. Scores from the 2011 study and 2020 were compared. Results: Michigan State and Ohio State Universities offered the most flexible policies (score 17.75/22) with the University of Michigan following (score 16.75/22). The largest delta scores, indicating more flexible policies in the past decade, were at University of Michigan (6) and University of Minnesota (5.25). Policies for parental leave and part-time faculty varied widely. Most schools earned an additional point in the newly added category of “flexible scheduling and return-to-work policies. ” Nearly every institution reported dedicated lactation spaces and improved childcare options. Limitations: Limitations included missing policy data and interpretation bias in reviewing the policy websites, unavailable baseline data for schools that joined the Big Ten after the 2011 study, and unavailable baseline data for the additional category of return-to-work policies. Conclusions: While progress has been made, every institution should challenge themselves to review flexibility in work-life policies for faculty. It is important to advance a healthy competition with the goal to achieve more forward-thinking policies that improve retention, recruitment, and advancement of faculty. Big Ten institutions can continue to advance their policies by providing greater ease of access to options, further expansion of parental leave and childcare support, and offering more flexible policies for part-time faculty.

OFDM Channel Estimation Along with Denoising Approach under Small SNR Environment using SSA

Abstract—In this paper, a de-noising approach in conjunction with channel estimation (CE) algorithm for OFDM systems using singular spectrum analysis (SSA) is presented. In the proposed algorithm, the initial CE is computed with the aid of traditional linear minimum mean square error (LMMSE) algorithm, and then further channel is evaluated by considering the low rank eigenvalue approximation of channel correlation matrix related to channel using SSA. Simulation results on bit error rate (BER) revealed that the method attains an improvement of 7 dB, 5 dB and 3 dB compared to common LSE, MMSE and SVD based methods respectively. With the help of statistical correlation coefficient (C) and kurtosis (k), the SSA method utilized to de-noise the received OFDM signal in addition to CE. In the process of denoising, the received OFDM signal will be decomposed into different empirical orthogonal functions (EOFs) based on the singular values. It was established that the correlation coefficients worked well in identifying useful EOFs only up to moderate SNR 12dB. For low SNR<12 dB, kurtosis was found to be a useful measure for identifying the useful EOFs. In addition to outperforming the existing methods, with this de-noising approach, the mean square error (MSE) of channel estimator is further improved approximately 1 dB more in SNR at the cost of computational complexity.
Incorporating Bank-Toe Erosion by Hydraulic Shear into the ARS Bank- Stability Model: Missouri River, Eastern Montana

Bank-stability concerns along the Missouri River, eastern Montana are heightened by a proposed change in flow releases from Ft Peck dam to improve habitat conditions for Pallid Sturgeon. The effects of the proposed flow releases on streambank pore-pressures and banktoe erosion needs to be evaluated to properly model bank-stability. The ARS Bank-Stability Model incorporates pore-water pressure distributions, layering, confining pressures, reinforcement effects of riparian vegetation and complex bank geometries to solve for the factor of safety (Fs). To increase the applicability and accuracy of the model for use in predicting critical conditions the hydraulic effects of bank-toe erosion have been added. Upper-bank stability is often a function of the degree of fluvial undercutting that occurs during rises in stage when the bank toe becomes submerged and steepened. This erosion, which is a function of the erodibility of previously failed materials and in situ sediments at the toe has been difficult to measure or estimate in the field. Recent field research on erosion of in situ cohesive streambeds and bank toes with a submerged jet-test device provides a means of calculating bank-toe erosion. Results of almost 200 tests at stream sites across the United States provide the following general relation: k =0 . 1τc –0.5 ;w herek = erodibility coefficient in cm 3 /N-s and τc = critical shear stress in Pa. Critical shear stresses are obtained in situ with the jet-test device (92 tests) for bank-toe materials along the Missouri River, Montana to obtain k and to calculate an erosion rate based on an excess shear-stress relation: e = k (τ - τc); where e = erosion rate in m/s and τ = average boundary shear stress in Pa. Inputs for the bank-toe erosion routine are: (1) a rectangular-shaped hydrograph of specified height and duration, (2) bed or water-surface slope, (3) flow depth, (4) bank geometry, and (5) τc for all bank layers and failed debris. Erosion is simulated normal to the submerged bank surface and the resulting bank geometry serves as input into the bank-stability part of the model. According to the proposed flow-release plan, flows of 216 m 3 /s are increased by 38.3 m 3 /s/day for 12 days to 675 m 3 /s, held for 60 days and decreased for 12 days back to 216 m 3 /s according. As expected, results show the important contribution of bank-toe erodibility in controlling mass failure. All sites modeled indicate a destabilizing influence (reduction in Fs) during the lowering of stage after 60 days, much of it due to lateral seepage and losses of matric suction and confining pressure. Banks at river miles 1624, 1676 and 1716 attain Fs < 1.0 indicating imminent failure. These sites contain less resistant sandy-silt material at the bank toe, and experienced simulated undercutting up to 3m. More resistant cohesive, clay bank toes at river miles 1589 and 1762 were undercut only 0.2 m and remained stable.
Picturing Mental Health on Instagram: Insights from a Quantitative Study Using Different Content Formats

Background: COVID-19 has changed individual lives to the core. Through national curfews and social distancing, individuals’ social lives changed and led to increased levels of stress and mental health problems. As another consequence, communication, especially among young people, has shifted to social networking sites, where particularly young adults sought help for their mental health problems. In recent years, Instagram has received recognition for its health-enhancing potentials. On this social networking site, more than 1 billion users worldwide post 500 million stories and images per day. Methods: During COVID-19, increasing mental health incidences were reported throughout the world, and have led mental health influencers to gain in relevance. The proposed study is based on a quantitative survey. In order to test how different content formats utilized by mental health influencers —motivational quotes, comics, or influencer posts—are evaluated by Instagram users, a cross-sectional quantitative study was conducted in April 2021. Data collection was based on convenience sampling. In total, 532 Austrian respondents between 16 and 34 years of age participated in the survey. Results: Overall, the content that received the most favorable evaluations were both the motivational quote (M = 4.23) and the influencer post (M = 4.12), while the comics scored lower in terms of evaluations (M = 3.72). Conclusions: Respondents’ preference of content suggests that individuals seek out content that boosts their esteem or content with a “human touch”. Explanations as to why the selected content formats were preferred over the other formats are offered alongside a future research outlook.
Metabolism and Health Effects of Rare Sugars in a CACO-2/HepG2 Coculture Model

Non-alcoholic fatty liver disease (NAFLD) has become the most prevalent liver disease worldwide and is impacted by an unhealthy diet with excessive calories, although the role of sugars in NAFLD etiology remains largely unexplored. Rare sugars are natural sugars with alternative monomers and glycosidic bonds, which have attracted attention as sugar replacers due to developments in enzyme engineering and hence an increased availability. We studied the impact of (rare) sugars on energy production, liver cell physiology and gene expression in human intestinal colorectal adenocarcinoma (Caco-2) cells, hepatoma G2 (HepG2) liver cells and a coculture model with these cells. Fat accumulation was investigated in the presence of an oleic/palmitic acid mixture. Glucose, fructose and galactose, but not mannose, l-arabinose, xylose and ribose enhanced hepatic fat accumulation in a HepG2 monoculture. In the coculture model, there was a non-significant trend (p = 0.08) towards higher (20–55% increased) median fat accumulation with maltose, kojibiose and nigerose. In this coculture model, cellular energy production was increased by glucose, maltose, kojibiose and nigerose, but not by trehalose. Furthermore, glucose, fructose and l-arabinose affected gene expression in a sugar-specific way in coculture HepG2 cells. These findings indicate that sugars provide structure-specific effects on cellular energy production, hepatic fat accumulation and gene expression, suggesting a health potential for trehalose and l-arabinose, as well as a differential impact of sugars beyond the distinction of conventional and rare sugars.
A Methodology to Derive a Symbolic Transfer Function for Multistage Amplifiers

In this paper, a simple while effective methodology to calculate the symbolic transfer function of a multistage amplifier with frequency compensation is proposed. Three general amplifier models are introduced and analyzed, which represent basic topologies found in the literature. For these amplifier models, the symbolic transfer function is derived and specific strategies for the zero and non-dominant pole expressions are presented. The methodology is suited for hand calculations and yields accurate results while offering more intuition into the operation of the widely adopted frequency compensation solutions discussed in the literature. The effectiveness of the proposed approach is validated through various typical cases of study.
Black Women in White Institutional Spaces: The Invisible Labor Clause and The Inclusion Tax

The dual pandemics brought on by COVID-19 and racial violence has played a significant role in uncovering how systemic racism is deeply entrenched within white spaces in America. This article examines the experiences of Black women lawyers in elite law firms to demonstrate how white institutional spaces are racially organized with embedded colorblind racist practices that work to obscure the insidious perpetuation of white supremacy. Black women are required to perform added, unrecognized, and uncompensated labor to maintain their positions. This invisible labor manifests in the form of an inclusion tax that they must pay to be included in white spaces. This article discusses how being one of very few Black people in white spaces creates a myriad of issues that require significant invisible labor including navigating white narratives of affirmative action, negotiating how dominant white culture functions to normalize the white experience, and adherence to white normative standards.
Designing A Provincial Surveillance and Support System for Childhood Cancer Survivors

Background Survivors of childhood cancer are at lifelong risk of morbidity (such as new cancers or heart failure) and premature mortality because of their cancer treatment. These are termed late effects. Therefore, they require lifelong, risk-tailored surveillance. However, most adult survivors of childhood cancer do not complete recommended surveillance tests such as mammograms or echocardiograms. Working with survivors, family physicians, and health-system partners, we are designing a provincial support system for high-priority tests, informed by principles of implementation science, behavioral science and design-thinking. Methods Our multi-phase process was as follows: Step 1: a qualitative study to explore intervention components essential to accessing surveillance tests; Step 2: a workshop with childhood cancer survivors, family physicians and health system stakeholders that used the Step 1 findings and ‘personas’ (a series of fictional but data-informed characters) to develop and tailor the intervention for different survivor groups Step 3: intervention prototype development; and step 4: iterative user-testing. Results The qualitative study of 30 survivors and 7 family physicians found a high desire for information on surveillance for late effects. Respondents indicated that in addition to providing personalized information, the intervention should help patients book appointments when they are due. Insights from the workshop included the importance of partnering with both family physicians and survivorship clinics and providing emotional support for survivors that may experience distress upon learning of their risk for late effects. In our user-testing process, prototypes went through iterations that incorporated feedback from users regarding usability and functionality. We sought to address the needs of survivors and physicians while balancing the capacity and infrastructure available for a life-long intervention via our health system partners. Conclusion In partnership with childhood cancer survivors, family physicians, and health-system partners, we elucidated the barriers and enablers to accessing guideline-recommended surveillance tests and designed a multi-faceted solution that will support survivors and their family physician. The next step is to evaluate the intervention in a pragmatic randomized control trial.
Bioengineered 3D microfibrous‐matrix modulates osteopontin release from MSCs and facilitates the expansion of hematopoietic stem cells

The osteopontin (OPN) released from mesenchymal stem cells (MSCs) undergoing lineage differentiation can negatively influence the expansion of hematopoietic stem cells (HSCs) in coculture systems developed for expanding HSCs. Therefore, minimizing the amount of OPN in the coculture system is important for the successful ex vivo expansion of HSCs. Toward this goal, a bioengineered three dimensional (3D) microfibrous‐matrix that can maintain MSCs in less OPN‐releasing conditions has been developed, and its influence on the expansion of HSCs has been studied. The newly developed 3D matrix significantly decreased the release of OPN, depending on the MSC culture conditions used during the priming period before HSC seeding. The culture system with the lowest amount of OPN facilitated a more than 24‐fold increase in HSC number in 1 week time period. Interestingly, the viability of expanded cells and the CD34+ pure population of HSCs were found to be the highest in the low OPN‐containing system. Therefore, bioengineered microfibrous 3D matrices seeded with MSCs, primed under suitable culture conditions, can be an improved ex vivo expansion system for HSC culture.

THE EFFECT OF BIG FIVE PERSONALITY ON FEAR OF MISSING OUT

This study aims to examine the influence of the Big Five Personality on Fear of Missing Out. Fear of missing out is the worry that individuals experience when other people experience impressive experiences in their absence, FOMO is characterized by the desire that the Big-Five Taxonomy does not aim to replace the existing system, but acts as an unifier because it can provide an explanation of the general personality system. In this study, the method used is a quantitative method with a population consisting of 284 students and the number of sample is 71 students of the Faculty of Psychology, University of Muhammadiyah Gresik. In this case the researchers used simple random sampling technique. The data analysis technique used multiple linear regression with a significant level of 5%. The result iss obtained that the value of r count = 0.453 then Ho is rejected and Ha is accepted. The result of the coefficient (r2) of r = 0.453 = 0.205, which indicates that the contribution of the Big-Five personality dimension with a fear of missing out is 20.5%, while the rest is by other variables not examined. Based on the data analysis, it can be concluded that there is a simultaneous influence of Big Five personality on fear of missing out.
