Neuroscience to Investigate Social Mechanisms Involved in Human-Robot Interactions

To what extent do human-robot interactions (HRI) rely on social processes similar to human-human interactions (HHI)? To address this question objectively, we use a unique corpus. Brain activity and behaviors were recorded synchronously while participants were discussing with a human (confederate of the experimenter) or a robotic device (controlled by the confederate). Here, we focus on two main regions of interest (ROIs), that form the core of "the social brain", the right temporoparietal junction [rTPJ] and right medial prefrontal cortex [rMPFC]. An new analysis approach derived from multivariate time-series forecasting is used. A prediction score describes the ability to predict brain activity for each ROI, and results identify which behavioral features, built from raw recordings of the conversations, are used for this prediction. Results identify some differences between HHI and HRI in the behavioral features predicting activity in these ROIs of the social brain, that could explain significant differences in the level of activity
DSOGI with proportional resonance controlled CHB inverter based two‐stage exalted photovoltaic integration in power system with power quality enhancement

: This study presents a grid-integrated solar photovoltaic system (SPVS). The objective of the work is to explore the scope of cascaded H-bridge multilevel inverter (CHBMLI) in the high infiltration of photovoltaic (PV) in the distribution system. A five-level CHBMLI is implemented with a balanced power-sharing and equal switch stress mode, which increases the system power rating with longer life. The power conversion efficiency is elevated by reduced switching frequency, compared to two-level inverters. The damped second-order generalised integral (DSOGI) control-based grid synchronisation is used to critically damp system oscillations and overshoots at dynamic operating conditions. Hence, safer service of lower rating power electronic switches at high power operation is ensured. It also has better bandpass filtering at the nominal grid frequency. A single-input multiple-output single-ended primary inductance converter realises the isolated DC sources for the CHBMLI. It extracts maximum power from the PV array by using centralised incremental conductance algorithm. The SPVS also considers the nonlinear unbalanced loads at the bus of common coupling and provide shunt active filter functionality. A minimum number of voltage and current sensors are used in the configuration. An extensive analysis is carried out to validate the theoretical claims.
Does Technology Lower the Cost of Education without Reducing Quality? A Financial Modeling Approach to Flipping the Classroom

Colleges and universities are rapidly expanding their use of technology to flip courses, where at least some of the content delivered synchronously in a traditional class is converted to asynchronous materials (e.g., recorded videos) the students learn from online in lieu of attending class. Flipped courses offer the potential to improve the quality of education and lower the cost of delivering it. However, the question of whether flipped courses are fulfilling this potential remains unanswered. I address this gap in the literature by developing a model that compares the cost of a flipped course to its traditional version. The model solves the problem of comparing the uneven cost structure of a flipped course, with its large upfront investment in asynchronous materials followed by lower subsequent costs because of the reduction in synchronous sessions, to its traditional version, with its relatively constant cost per offering. With this model, a new pooled cross-section database consisting of 2,060 students enrolled in seven cohorts over a six-year period, and the application of rigorous educational-quality metrics, I test the hypothesis of whether technology lowers the cost of education without diminishing quality. I report consistent evidence of a significant decrease (36% on average) in the cost of developing and delivering a flipped course relative to its traditional version without a reduction in quality. I also show the circumstances under which a flipped course can be more expensive than its traditional version, and demonstrate how the model can be a practical tool for deciding when it makes sense to invest in technology and how to do so.

Study of free and occluded particulate organic matter in soils by solid state 13C Cp/MAS NMR spectroscopy and scanning electron microscopy

A simple densimetric method for the separation of free and occluded particulate organic materials was developed and applied to five virgin soils. The free organic matter was isolated by suspending the soil in sodium polytungstate solution (d = 1.6 Mg m-3) and decanting the light material. The remaining soil was disaggregated by sonification for liberation of occluded organic materials. The free light fraction consisted of large, undecomposed or partly decomposed root and plant fragments. This fraction comprised 0.59-4.34% of soil dry weight and accounted for 6.9-31.3% and 5.9-22.1% of total soil carbon and nitrogen respectively. Identifiable components of the occluded fraction were small particles of incompletely decomposed organic residues, pollen grains, particles of plant tissue such as lignin coils and phytoliths. This fraction comprised 0.69-1.81% of soil dry weight and represented 9.2-17.5% and 6.2-14.1% of the total soil carbon and nitrogen. The proportion of soil organic carbon recovered as the occluded fraction was high in soils with high clay contents. The chemical composition of occluded and free organic materials was investigated by solid-state 13C CP/MAS NMR spectroscopy. Despite the differences in soils, environmental conditions and vegetation, the organic structure of the free light fraction was similar in four of the five soils. This fraction consisted of 55-63% O-alkyl C, 18-25% alkyl C, 14-18% aromatic C, and 5-7% carbonyl C. In the other soil, this fraction showed a higher proportion of alkyl C (31%) and lower O-alkyl C (46%). Most of the differences between soils were associated with organic materials contained in the occluded light fraction. The differences in chemical structure between the occluded light fraction and free light fractions were similar in all examined soils. The NMR data showed that the proportion of O-alkyl C was lower and alkyl C higher in the occluded light fractions than in the free light fractions. The proportion of aromatic and carbonyl carbon was higher in the occluded fractions of three soils while the percentage of these two types of carbon remained unchanged in the two other soils. It is considered that the occluded organic matter is an old pool of carbon that has been accreted within aggregates during decades of root growth and it is that pool which is lost due to cultivation.

“It’s Raining Bits”: Patterns in Directional Precipitation Persistence across the United States

The spatial and temporal ordering of precipitation occurrence impacts ecosystems, streamflow, and water availability. For example, both large-scale climate patterns and local landscapes drive weather events, and the typical speeds and directions of these events moving across a basin dictate the timing of flows at its outlet. We address the predictability of precipitation occurrence at a given location, based on the knowledge of past precipitation at surrounding locations. We identify “dominant directions of precipitation influence” across the continental United States based on a gridded daily dataset. Specifically, we apply information theory–based measures that characterize dominant directions and strengths of spatial and temporal precipitation dependencies. On a national average, this dominant direction agrees with the prevalent direction of weather movement from west to east across the country, but regional differences reflect topographic divides, precipitation gradients, and different climatic drivers of precipitation. Trends in these information relationships and their correlations with climate indices over the past 70 years also show seasonal and spatial divides. This study expands upon a framework of information-based predictability to answer questions about spatial connectivity in addition to temporal persistence. The methods presented here are generally useful to understand many aspects of weather and climate variability.
Advancement in Cancer Immunotherapy in Veterinary Medicine: A Review

Cancer is one of the leading cause of death in human beings throughout the world. Attempts to treat cancer are made but not effectively. Surgical removal, use of radiation therapy, chemotherapy and combination of these therapies have been tried to cure cancer but every therapy had its own side effects. Due to potential side effects, these therapies failed to develop as the permanent cure for cancer. Stem cell transplantation has also been attempted as an alternative but the recovery rate was very low. The most recent therapy, nowadays, to treat cancer is immunotherapy in which utilises the immunity of the patient to get modulated in such a way that cancerous cells get killed. So this review enlightens the eminent immunotherapies used for veterinary patients. T cell checkpoint inhibitors, engineered T cells, cancer vaccines, and anti-B and anti-T cell antibodies are amongst the important immunotherapies used in human as well as veterinary patient. Inhibition of T cell checkpoint molecules, such as PD-1 and CTLA-4, using monoclonal antibodies are the most advanced techniques developed in humans. These significant immunotherapies have achieved notable success against some of the advanced tumors in humans, including melanoma, renal cell carcinoma and non small cell lung cancer. However, a recent clinical trial with a caninized monoclonal antibody against canine PD-L1 showed response in canine melanoma.

Electrical Properties of Silica‐Based Nanocomposites with Multiwall Carbon Nanotubes

Fully dense multiwall carbon nanotubes (MWCNT)/SiO2 nanocomposites with MWCNTs contents of 5 and 10 vol% have been processed by spark plasma sintering, and the electrical conductivities of the nanocomposites were evaluated at temperatures ranging from 5 to 300 K. It has been found that the incorporation of MWCNTs converted an insulating silica nanoceramic into metallically conductive composites. The room-temperature conductivities of the nanocomposites, with over 14 orders of magnitude compared with pure silica, are in the range of 8 and 65 S/m. Also, it was interestingly found that the conductivity increased linearly with temperature from 5 to 300 K.
A Web-Based Platform to Teach Music Online

—The development of educational technology has encouraged music educators to consider different ways to teach music online. However, this change may need an online platform to support teachers when the size of the class is large. This paper aims to address two research questions. The ﬁrst question is to determine the learning experiences of students and to understand their needs to support Web-based learning. The second question is to study the key technologies required for a Web-based music teaching system. In this paper, we try to determine the best ways to motivate students to study music and to make music teaching experiences more accessible, engaging, and fun for students.
Quantum-Chemical Studies on TATB Processes

Quantum chemical studies have gained paramount importance in screening of thermodynamically feasible chemical processes. The current investigation attempts to select an appropriate process for the synthesis of 1,3,5-triamino-2,4,6-trinitro benzene (TATB), a reasonably powerful insensitive high explosive (IHE) through density functional theory (DFT) calculations. Although, 1,3,5-trichlorobenzene (TCB) and 1,3,5-trihydroxybenzene (THB) routes for synthesis of TATB have been well established, this article demonstrates the predictive capability of thermochemical computations for the identification of a viable process. Thermochemical parameters of reaction species have been obtained from DFT B3LYP/6-31G* calculations and feasibility of the process has been worked out on the basis of free energies of reactions and equilibrium constant as derived from standard enthalpy and entropy of the reaction species. The detailed computational studies have revealed that the THB route is thermodynamically feasible and the same has been supported experimentally.
Factors Affecting the Client's Performance in the Public Construction Projects: Case Study of Oman

Despite the vast research on construction projects management issues in the Middle-East, little is known about client involvement in public projects. This article presents a study on identifying significant factors affecting client participation performance in public construction projects in the Sultanate of Oman. The study was conducted in quantitative approach where the data was collected through questionnaire survey. The collected data was analysed statistically to determine the ranking of the identifiedfactors based on the degree of involvement in the project. The study found that the handover phase had the highest client’s participation, while the operations and maintenance phase had the lowest client’s participation among all the five construction phases. The low client participation in any project has an undesirable influence on the projects’ overall outcomes. Consequently, this condition has harmed the time of completion of construction projects in the Sultanate of Oman. This condition is also the main reason for the quality problems in construction projects in Oman.
FORENSIC LINGUISTICS OF HOAX TEXT ABOUT COVID-19 ISSUES THAT HANDLED BY POLICE STATION OF BENGKAYANG, WEST KALIMANTAN

Abstract : This paper is a study of the alleged hoax news regarding the announcement of an area in Yogyakarta that was all positive COVID-19. This news became noisy in Facebook of Bengkayang Informasi so make the Bengkayang Criminal Detective Unit Team processed the case. This study aims to describe the alleged lies of the news spread on Facebook's as social media. This type of research is qualitative. This paper uses a documentary study using report data processed by Bengkayang Police investigators. The method used to analyze data is to use the forensic linguistic approach by describing the forensic semantics. This semantic analysis is contrasted with other texts that explain the facts of the case. The results of this study indicate that the news disseminated has the potential to violate the law because it is suspected to contain elements of lies.
Spin relaxation by collective director fluctuations and molecular diffusion in lamellar phases. Continuum theory of relaxation anisotropy and dispersion

The orientation and frequency dependence of nuclear spin relaxation rates can provide detailed information about the amplitudes and rates of collective orientational fluctuations (director fluctuations) in liquid crystals. In particular, the low-frequency spin relaxation rates from a lamellar phase reflect the membrane bending rigidity and the intermembrane forces. This information is contained in three spectral density functions Jn(ω), n=0,1,2. We have recently presented a continuum-mechanical theory for the second-order spectral density J1(ω). Here we extend the theory to the fourth-order spectral densities J0(ω) and J2(ω), which dominate the transverse relaxation rate in the parallel and perpendicular configurations. These spectral densities have previously been considered in connection with director fluctuations in nematic phases, neglecting the elastic and hydrodynamic anisotropy of the phase. In lamellar phases, this anisotropy plays a crucial role and must be retained in the relaxation theory. Dire.
Adsorption of Lactic Acid on Weak Base Polymeric Resins

Abstract Sorption of lactic acid from a simulated broth has been investigated using weak base ion exchange polymeric resins which behave as functionalized polymers because of tertiary amino groups on the polymer matrix. The equilibrium data for the uptake of lactic acid are represented by Langmuir‐Freundlich combination isotherm. The sorption has been modeled by a phase equilibrium approach using the extended Flory‐Huggins theory of polymer solutions. The interaction of media components, such as glucose and inorganic salts, with the resins and their effect on lactic acid sorption, also has been investigated.
Real-Time Prediction of Online False Information Purveyors and their Characteristics

Disinformation, misinformation, and other 'fake news' - collectively false information - is quick and inexpensive to create and distribute in our increasingly digital and connected world. Identifying false information early and cost effectively can offset some of those operational advantages. In this paper, we develop light-weight machine learning models that utilize (1) a novel data set tracking browsing behavior and (2) domain registration data that is available for all websites when they are established. Using only the domain registration data, we develop and demonstrate a machine learning classifier that identifies domains, at the time the domain is registered, that will go on to produce false information. We then combine this data with our browsing data and develop a machine learning classifier that identifies false information domains whose content is most associated with higher levels of consumption. Finally, we use our data to identify false information domains that will cease operations after an event of interest, in our case the 2016 U.S. presidential election. We theorize that the last category involves actors seeking primarily to manipulate perceptions and outcomes of that event.
Extent and Severity of Coronary Artery Disease as Predictors of Myocardial Reperfusion in Acute Coronary Syndrome

Background: Worldwide, Coronary Artery Disease (CAD) is the single most frequent cause of death. Over seven million people every year die from CAD, accounting for 12.8% of all deaths. Every sixth man and every seventh woman in Europe die from Myocardial Infarction (MI). Objectives: To assess the extent and severity of coronary artery disease as predictors of myocardial reperfusion in acute coronary syndrome. Patients and Methods: A prospective cohort study included patients admitted with Acute coronary syndrome after approval from the Research and Ethics Committee of Faculty of Medicine, Menofeya University from January 2015 to January 2020. They divided into two groups: Group (I): included patients with ST Elevation Myocardial Infarction (STEMI) in whom primary Percutaneous Coronary Intervention (PCI) done or pharmacoinvasive therapy either total or subtotal revascularization. Group (II): included patients with Non-ST Segment Elevation Myocardial Infarction (NSTEMI and UA) in whom PCI done either total or subtotal revascularization. Results: The cutoff value of Troponin, CK and CKMB in prediction of myocardial reperfusion in acute coronary syndrome. Our ROC results revealed that Troponin, CK and CKMB cutoff value is greater than 20, 440, and 50 and the area under the ROC curve is equal to 0.796, 0.732 and 0.690 which indicating that they are fair predictors for myocardial reperfusion in acute coronary syndrome. The sensitivity values of Troponin, CK, and CKMB were 78.2, 77.3 and 70 respectively and the specificity values of Troponin, CK and CKMB were 66.4, 65.7 and 64.3 respectively. Conclusion: Our study indicated that there is a significant Association between both syntax score and extent of CAD and Myocardial perfusion.
