Learning of Tool Force Adjustment Skills by a Life-sized Humanoid using Deep Reinforcement Learning and Active Teaching Request

The purpose of this study is to make life-sized humanoid robots acquire tool manipulation skills that require complicated force adjustment. The difficulty in acquisition of tool manipulation skills comes from the hardship in physical modeling. Recent research have revealed that deep reinforcement learning (DRL), a model-free approach, performs superior in such tasks. However, DRL in general has a drawback in sample efficiency, and this becomes critical in robot learning especially in life-sized humanoid robots. In this study, we propose an integrated system incorporating DRL method and active learning. Our method also leverages a variety of previous studies on life-sized humanoid robots to overcome the sample efficiency issue. We demonstrated the effectiveness of our proposed system through a hacksaw skill acquisition and a Japanese planer (Kanna) skill acquisition by a life-sized humanoid robot.
Growth performance and small intestinal morphology of native chickens after feed supplementation with tryptophan and threonine during the starter phase

Background and Aim: The amino acid content of feed can affect growth performance of poultry during the first 6 weeks of life or the starter phase. Unlike for broiler and layer chickens, there is no information concerning standard requirements for tryptophan and threonine during the starter phase. This study aimed to determine the amount of threonine and tryptophan that should be supplemented in chicken feed to maximize growth performance and small intestinal morphology of native chickens during the starter phase. Materials and Methods: A total of 128 day-old native chickens were divided into four treatment groups with four replications based on a completely randomized design. The treatment diets were as follows: T0 (control feed); T1 (T0+0.10% L-tryptophan+0.35% L-threonine); T2 (T0+0.17% L-tryptophan+0.68% L-threonine); and T3 (T0+0.25% L-tryptophan+1.00% L-threonine). Results: The feed intake was highest for the T2 and T3 groups (123.06 and 124.18 g/bird/week, respectively). The T3 group had the highest body weight gain (49.35 g/bird/week) and carcass weight (201.44 g/bird) relative to the other groups, while the T2 and T3 groups showed similar, significant (p<0.05) increases in feed conversion ratio (2.57 and 2.51, respectively) and carcass percentage (60.88 and 60.99%/bird, respectively) compared to the other groups. This study showed villi height, crypt depth, and villi width of duodenum, the highest jejunum and ileum of T3 (1109.00±27.26, 1325.50±75.00, 1229.50±101.68, 225.50±17.52, 236.00±24.81, 219.75±17.25, 192.25±14.41, 191.75±4.79, and 184.75±6.40, respectively) compare to other treatment. Conclusion: These results indicate that supplementation of feed with 0.17% L-tryptophan and 0.68% L-threonine positively affected the growth performance and small intestinal morphology of native chickens during the starter phase.
Cost-Efficient RAA Technology for Development of the High-Gain Steerable Antennas for mmWave Communications

For the future millimeter wave wireless systems the high gain steerable antennas are the key technology to overcome large path loss and support users’ mobility and reconfigurable backhauling. This paper introduces a specially designed reflect-array antenna (RAA), integrating single phased antenna array (PAA) module (as a feed source) and flat reflecting surface. The RAA provides high antenna gain by focusing the beam in vertical plane, but, at the same time, supporting beamsteering capability in the horizontal plane. The RAA technology allows creation of the very larger aperture antennas with simplified light-weight design. Two RAA prototypes with different feed source mounting demonstrated reliable multi-gigabit IEEE 802.11ad link 2.3–4.62 Gbps at distances 100–150m. These properties of the RAAs make them suitable for both millimeter-wave mobile access and reconfigurable backhauling applications.
Effect of chemical treatment on the thermoelectric properties of single walled carbon nanotube networks

Carbon nanotube networks showing superior electric properties, high chemical stability, strong mechanical properties, and flexibility are also known to exhibit thermoelectric effects. However, the experimental thermoelectric figure of merit, ZT, of pristine carbon nanotubes is typically in the range of 10−3–10−2, which is still not attractive for thermal energy conversion applications. In this work, we show possible ways to improve the thermoelectric properties of single walled carbon nanotubes (SWCNTs) by means of chemical treatments. In this study, we primarily investigated the effect of chemical treatment on the electrical conductivity and thermoelectric power (TEP) of the entangled network of nanotubes, also, known as “buckypaper”. This chemical treatment increased the electrical conductivity due to p‐type doping, thereby, showing a decrease in the TEP given by the Seebeck coefficient, whereas the n‐type dopants changed the sign and value of the TEP from about 40 to −40 µV K−1. Neutral polymers, in terms of doping, such as PVDF, PMMA, PVA, PS, and PC, were expected to hinder phonon transport through the nanotube network, increasing the Seebeck coefficient up to ca. 50 µV K−1. Our results reveal the importance of chemical doping determining the sign and the magnitude of the TEP, and role of the polymer matrix in the development of more effective thermoelectric composites based on carbon nanotubes.

Well Oiled Machine: Classifying Machinery Performance Reductions Using Work Order Data

Work Order (WO) data from System Applications and Products in Data Processing (SAP) software contains valuable information about what WOs intend to accomplish. Using SAP work order data, with time-series machinery sensor data combined into the same dataset, provides an opportunity to optimize prediction models to increase performance. Ideally, WO data can be utilized to help predict machinery's anticipated performance and can help prioritize a WO among others based on the anticipated machinery performance. It is possible to identify anomalies in pump sensor data using the Isolation Forest algorithm as the method for anomaly detection. The relationship between the sensor data and the WO data is not straightforward due to scheduled maintenance programs, causing anomalies in the data and periods where a pump has experienced higher than normal performance. Autoregressive integrated moving average (ARIMA) provides additional insight from a time series perspective but may not necessarily provide different results. However, some anomalies did show that some advance notice or other factors that could be used for elevating the priority of a work order. Further analysis in what is considered to be a “good” and a “bad” anomaly may need additional research to enable a more efficient approach to detection with respect to WO prioritization of “bad” anomaly data.
First-principles calculations of dielectric constants for ultrathin SiO2 films

We studied the dielectric properties of ultrathin SiO2 films using two methods, internal field method and dipole moment method, based on first-principles calculations of the ground state in a finite electric field. We evaluated the optical and static dielectric constants, e∞ and e0, of H-terminated β-quartz (0001) films through calculations without and with the lattice relaxation in the electric field applied, respectively. The calculated values of e∞ and e0 with these two methods are in good agreement with each other, and they reproduce well the experimental values. Both the optical and static dielectric constants hardly depend on the film thickness, and the spatial variation of the local dielectric constant is also very small. These results indicate that both the surface effect and the quantum confinement effect are small for the ultrathin H-terminated β-quartz (0001) films.
Estudo de Detectores de Baixa Complexidade para Sistemas MIMO-OTFS

Resumo— As transmissões de dados sem fio em canais variantes no tempo e com alta dispersão Doppler são desafiadoras. Assim, foi proposta a modulação orthogonal time-frequency space (OTFS) que apresentou vantagens significativas em canais duplamente dispersivos. O modelo de canal na modulação OTFS é esparso, permitindo usar algoritmos de baixa complexidade para detecção. Neste artigo, o desempenho da modulação OTFS para sistema MIMO é avaliado para algoritmos de "passagem de mensagens"aproximados. Os resultados mostram que os algoritmos têm desempenhos semelhantes e superam significativamente o estimador MMSE. Além disso, o algoritmo aproximado de primeira ordem é sugerido como melhor bom custo-benefício.

4-year recurrence risk factors after tension-free vaginal tape-obturator as a treatment of stress urinary incontinence

Objectives: Tension-free vaginal tapes are the gold standard of the surgical treatment of stress urinary incontinence (SUI); however, long-term recurrence of SUI after this surgery has been a matter of problem. Here, we attempted to determine the incidence of its recurrence and to identify the risk factors of 4-year-recurrence of SUI after this surgery. Methods: Of all patients undergoing this surgery (n = 341, 2015-2019), 71 patients were met the study inclusion criteria. Of 71, SUI recurred in 8 patients, with the recurrence rate being 11.3%. The following three were identified to be independent risk factors: older age, history of delivery of macrosomic baby (>4 kg), and the presence of mixed urinary incontinence. The frequency of recurrence in cases with mixed incontinence amounted for 19.5%. Recurrence was 22 and 50% for women with macrosomic delivery once and more than twice, respectively. Conclusion: Advanced age, macrosomic delivery and mixed urinary incontinence have shown to be independent risk factors of recurrence of SUI after tension-free vaginal tape-obturator at 4 years. Key message: Stress urinary incontinence can recur so investigate possible risk factors is a priority. Our paper relates recurrence with: advanced age, fetal macrosomia and mixed incontinence.
Effect of principals' relationship management on the organisational commitment of teachers in secondary school in county governments in Kenya

The purpose of this study was to investigate the influence principals’ relationship management (RM) on the organizational commitment (OC) of secondary school teachers in county governments in Kenya as moderated by teachers’ self-efficacy. This study hypothesized that principals’ RM has no significant relationship on the teachers’ OC. Survey research design was employed to establish the relationship between principals’ RM and teachers’ OC. Simple random sampling was used to draw a sample of 120 principals and 480 teachers from Nairobi, Machakos, Kajiado, and Kiambu counties in Kenya. The method of data collection was through the use of questionnaires. This study established that principals’ RM was a significant predictor of teachers’ OC. The study also established that teachers’ self-efficacy moderated the relationship between principals’ RM and teachers’ OC and that self-efficacy had positive influence on teachers OC. The study recommends that Teachers’ Service Commission (teachers’ employer) should put more emphasize on training of RM among principals in secondary schools in Kenya. This study makes useful contribution in the advancement of knowledge on the effects of principals’ RM on teachers’ OC in Kenya.
Sensitivity of the freshwater tropical oligochaete, Branchiura sowerbyi (Beddard, 1892) to the grey list metal, Zinc

Although the freshwater oligochaete, Branchiura sowerbyi Beddard, 1892 (Oligochaeta: Naididae: Rhyacodrilinae) has been used as an indicator organism to monitor aquatic pollution, the data on the toxic effects of the grey list metal, zinc on this worm is remained scanty. The present study was undertaken to determine the sensitivity of the worm, B. sowerbyi to zinc on the basis of 24, 48, 72 and 96h lethal concentrations (LC1, 5, 10, 15, 50, 85, 90, 95, 99) and their behavioural responses. The 96h LC50 value of zinc with 95% confidence limit to the worm was recorded as 45.48 (41.32-49.33) mg/l. The rate of mortality of the worm was significantly increased (p<0.05) with increasing concentrations and time of exposure (24, 48, 72 and 96h). The study further focussed on estimation of the toxicity factor at different time scale and possible safe level of zinc to the worm to strengthen the base line data that could be used to set up local water quality criteria (WQC) for the toxicant. The worms showed behavioural changes like clumping tendency, movement and mucous secretion with increasing concentration of the toxicant and the progress of time. The findings can be used in determination of ecological risk assessment for the worm to zinc toxicity as well as to understand its mode of action in the light of their ethological changes. Keywords: Zinc, Branchiura sowerbyi, acute toxicity, toxicity factor, safe level, behavioural responses

The way through which financial distress impact companies is the core of the economy especially after the COVID 19 wave all over the world. The main aim of the paper is to test the impact of Financial distress, firm size, and audit quality on earnings management. The study is applied on a sample of 42 companies listed in the Egyptian stock exchange market from the period 2015-2017. The paper main contribution is to add to the accounting literature of the financial distress and earnings management in the Egyptian environment as one of the leading developing countries in MENA region. The main research objective is to examine the relation between the financial distress, firm size, and audit quality from one side and earnings management from other side. This can help in understanding the behavior of earnings management in practice regarding these stressful variables. The researchers used regression analysis to find out the specific causal relationship among the research variables. The research results show that financial distress and audit quality are significantly impacting earnings management practices meanwhile the study failed to find a significant effect for firm size on earnings management within the Egyptian companies listed in the stock exchange market. The regression model include both variables and excluding firm value showed a 48.6% explanation power for explaining the change in the dependent variable. The limitation of the research is related to the other variables not considered in the study and the time period that included only 2015-2017. The main recommendation of the researchers that this study to be extended to include larger sample and a recent period to include the financial distress resulted by COVID 19 pandemic.
Acute oral toxicity study of ethanol extract of Oroxylum indicum leaf in mice

The Oroxylum indicum plant is a herbal plant commonly eaten by the locals in Malaysia while the application of herbal remedies from the plant has been inherited and passed down through generations. However, there is a lack of toxicity profiling of the plant, hence this research aimed to investigate acute oral toxicity of ethanol extract of O. indicum in C57BL/6 male mice at different concentrations, to determine the LD50 of the plant extract. A total of twenty-five mice were randomly assigned into five experimental groups comprising the control (normal saline), vehicle (5% DMSO), low dose (1000 mg/kg bw), medium dose (2000 mg/kg bw) and high dose (5000 mg/kg bw). The extracts were administered in a single oral dose on day 1 and the mice were observed daily for mortality, physiological and behavioural changes throughout the 14 day study period. At the end of the study, vital organs and blood samples were collected to determine the effects of the extract on the relative organ weight, tissue changes and blood profile alterations. No mortality nor behavioural changes were recorded for 2 weeks. Results of the body weight, relative organ weight, haematological and serum biochemistry assessments showed no significant (p>0.05) changes. Nevertheless, there were significant differences in the mean corpuscular volume (MCV), urea and alanine transaminase (ALT) values but the levels were still within the normal range. Histopathological analysis of the liver and kidney tissues also revealed no striking lesions. In summary, this study indicates that O. indicum leaf ethanolic extract up to 5000 mg/kg bw did not cause any toxicological effects in the mice model and is safe to be used for therapeutic purposes.

304 Educational tools promoting biosecurity through discovery learning

Education is the most important component in creating and sustaining a healthy national agriculture industry. As part of a large USDA NIFA Coordinated Agricultural Project, we created education products for youth and an online resource, the Healthy Farms Healthy Agriculture (HFHA) website, to help existing and future farmers and ranchers discover how to create and implement a biosecurity plan for their livestock farms. A national team of three subject matter experts, led by a distance education expert, created a series of six biosecurity modules designed for youth audiences between 6thand 12thgrade. Four modules cover biosecurity basics, disease transmission risks, and biosecurity strategies while the last two prepare youth to be biosecurity advocates by helping them create and deliver a persuasive presentation. We used discovery learning to engage students and improve comprehension and retention. In the process of development and deployment of the modules we employed a thorough review process with peer reviews and pilot testing of each of the modules. Peer-reviewers were asked to evaluate the modules on multiple aspects of five dimensions: content, interactivity, effectiveness, usability, and versatility. Modifications were made based on these reviews and the low-end of the target audience was increased from 3rdto 6thgrade. FFA and 4-H youth and adult leaders piloted the revised modules for various parameters including content, effectiveness, and recommendations for improvement. Feedback was used to finalize the modules which were then published on the HFHA website. A summative evaluation plan has been created. We will demonstrate all the products and share formative and summative evaluation tools and results for the biosecurity educational series. All evaluation procedures have the approval of the Institutional Review Board at Washington State University. Funding for this effort is partially supported by the National Institute of Food and Agriculture, US Department of Agriculture, under award number 2015-69004-23273.
Relationship between APO-A, APO-B, and C-reactive Protein with Depression in Epileptic Patients

Background: Epilepsy is one of the oldest neurological disease requiring long-term treat­ment. Long-term use of certain anti-epileptic drugs (AED) will strongly induce cytochrome-P450 (CYP) enzyme resulting increase of homo­cysteine associated with risk of cerebrovascular disease and depression. The purpose of this study was to determine relationship between serum level of ApoA, ApoB, and C-Reactive Protein (CRP) with depression in epileptic patients receiving AED therapy. Subjects and Method: Respondents of this cross-sectional study were epileptic outpatients in neurology clinic Dr. Moewardi Hospital, Surakarta receiving AED therapy and met inclusion and exclusion criteria. Depression condition was evaluated by Hamilton Depress­ion Rating Scale (HDRS). Serum level of ApoA, ApoB, and CRP of each respondent were mea­sured from vein blood. Data were analyzed by a multiple linear regression. Results: There were 51 epileptic patients with proportional ratio between men and women (1.2:1) with age range from 18 to 59 years old. The average length of AED 92.67 months (Mean= 92.67; SD= 91.58). Average of HDRS score was 8.49. Meanwhile, average of ApoA level was 86.14 mg/dL, average of ApoB level was 47.57 mg/dL, and average of CRP level was 0.18 mg/dL. Serum level of ApoA, ApoB, and CRP increased depression (HDRS score) in epileptic patients. Conclusion: There was a statistically signi­fi­cant relationship between serum level of ApoA, ApoB, and CRP with depressive condi­tion of epileptic patients receiving long-term AED treatment.
