Grade Prediction in Blended Learning Using Multisource Data

Field: Computer Science (Physical Sciences)

Today, blended learning is widely carried out in many colleges. Different online learning platforms have accumulated a large number of fine granularity records of students’ learning behavior, which provides us with an excellent opportunity to analyze students’ learning behavior. In this paper, based on the behavior log data in four consecutive years of blended learning in a college’s programming course, we propose a novel multiclassification frame to predict students’ learning outcomes. First, the data obtained from diverse platforms, i.e., MOOC, Cnblogs, Programming Teaching Assistant (PTA) system, and Rain Classroom, are integrated and preprocessed. Second, a novel error-correcting output codes (ECOC) multiclassification framework, based on genetic algorithm (GA) and ternary bitwise calculator, is designed to effectively predict the grade levels of students by optimizing the code-matrix, feature subset, and binary classifiers of ECOC. Experimental results show that the proposed algorithm in this paper significantly outperforms other alternatives in predicting students’ grades. In addition, the performance of the algorithm can be further improved by adding the grades of prerequisite courses.
The McGill Thyroid Nodule Score's (MTNS+) role in the investigation of thyroid nodules with benign ultrasound guided fine needle aspiration biopsies: A retrospective review

Field: Medicine (Health Sciences)

Background Ultrasound guided fine needle aspiration (USFNA) biopsies of thyroid nodules sometimes create a decision-making dilemma for surgeons as they may yield falsely benign results. The McGill Thyroid Nodule Score + (MTNS+) was developed to aid in clinical guidance regarding the management of patients with these USFNA results. The aim of this study was to assess the MTNS+ as a clinical tool in patients with benign preoperative thyroid nodule USFNAs and to analyze the relationship between nodule size and malignancy in these patients. Methods We conducted a retrospective chart review of 1312 patients who underwent thyroidectomies between 2010 and 2015 at the McGill University Teaching Hospitals. Patients with Bethesda II (benign) USFNA results, calculated MTNS+, and nodule size evaluated on ultrasound were included in the study. The false-negative rate was calculated, and MTNS+ and nodule size were each compared to final pathology results. Binary logistic regression was used for statistical analysis. Results Of the 1312 patients, 101 met the inclusion criteria and together had an average MTNS+ score of 6.83, which corresponds to a predicted malignancy rate between 25 and 33 %. Final pathology revealed malignancy in 16 (15.8 %) subjects. The average MTNS+ of patients with malignant nodules on surgical pathology was 8.25, while that of patients with benign nodules was 6.56. Patients with nodule size 1–1.9 cm (a) and 2–2.9 cm (b) each had an equal rate of malignancy of 2.97 % ( n = 3), nodule size 3–3.9 cm (c) had a rate of 1.98 % ( n = 2), and nodule size ≥4 cm (d) a rate of 7.92 % ( n = 8). Conclusion The rate of malignancy (15.8 %) is higher than expected when reviewing the risk of malignancy in nodules considered as Bethesda class 2. On the other hand, the rate is lower than the 25–33 % predicted by the MTNS+. We also found a higher malignancy rate for nodules above 4 cm in size, but size was a poor predictor of malignancy when used alone. Therefore, while the MTNS+ may be helpful at helping to identify USFNAs that are incorrectly classified as benign, the percentage risk of malignancy is lower than expected.
The end of the globalization debate: continued

Field: Social Sciences (Social Sciences)

This brief essay pursues a line of argument that I deployed in a review article in the Harvard Law Review, discussing several important recent books about globalization. The thesis is that there is no longer a meaningful or important debate for or against globalization because the anti-globalizers have themselves gone global. In various sites of global law and policy-making, including those at the interstices of the global and local (as will be explained), the anti-globalizers actually found processes and institutions where, unlike the case with the ‘state’ in many instances, they could air their criticisms of policies and express their values as global values. Despite the continuing rhetoric and polemics regarding the promotion of globalization, there is no longer an anti-globalization ‘side’ in the debate, coherently representing the position that the territorial nation-state is and should remain the locus of control over economic activity and that it should retain a monopoly on legitimate governance. Today the protesters who march against ‘globalization’ are not marching in favor of the ‘state’. Instead, they are, mostly, advocating a set of values and causes that transcend state boundaries and that require global action. Anthony Giddens anticipated, at the beginning of this century, that the debate would re-focus as a debate about globalization, rather than whether globalization should take place (as I learned after writing my Harvard essay).
Analysis of stress-structural collapse mechanism of columnar jointed basalt under high stress

Field: Earth and Planetary Sciences (Physical Sciences)

Columnar jointed rock mass with unique joint network structure is a special type of jointed rock mass, which is a binary structure composed of high strength ‘basalt block’ and specific ‘dominant joint’. Relaxation, opening and slippage of columnar jointed surfaces and disintegration of columns occur easily during excavation under high ground stress, which eventually lead to disastrous collapses in columnar jointed rock mass. The construction safety of underground engineering under high stress is severed restricted by it. By combining acoustic wave, borehole camera and other integrated in-situ testing technology and numerical simulation, the mechanism of stress-structural collapse in columnar jointed rock mass under high stress is studied based on multiple columnar jointed rock mass collapses at left bank tailwater connection pipe of Baihetan hydropower station. The proposed controlling measures of excavation and support are also provided. The key of columnar joined rock mass collapse is the redistribution of stress in surrounding rock mass after the excavation and the strong unloading relaxation of columnar joined basalt, which causes the opening of its internal joint surfaces and structural deterioration, result in the disintegration of basalt columns. Thus, the chain catastrophic process of continuous unloading relaxation and progressive collapse of columnar jointed rock mass is induced. The research can provide reference for the prediction and control of deformation and failure of jointed rock masses in underground engineering under high geo-stress.
Genome-Wide Analysis of Cyclophilin Proteins in 21 Oomycetes

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Cyclophilins (CYPs), a highly-conserved family of proteins, belong to a subgroup of immunophilins. Ubiquitous in eukaryotes and prokaryotes, CYPs have peptidyl-prolyl cis–trans isomerase (PPIase) activity and have been implicated as virulence factors in plant pathogenesis by oomycetes. We identified 16 CYP orthogroups from 21 diverse oomycetes. Each species was found to encode 15 to 35 CYP genes. Three of these orthogroups contained proteins with signal peptides at the N-terminal end, suggesting a role in secretion. Multidomain analysis revealed five conserved motifs of the CYP domain of oomycetes shared with other eukaryotic PPIases. Expression analysis of CYP proteins in different asexual life stages of the hemibiotrophic Phytophthora infestans and the biotrophic Plasmopara halstedii demonstrated distinct expression profiles between life stages. In addition to providing detailed comparative information on the CYPs in multiple oomycetes, this study identified candidate CYP effectors that could be the foundation for future studies of virulence.

CHILD’S RIGHTS PECULIARITIES: GENERAL AND LEGAL ASPECT

Field: Social Sciences (Social Sciences)

Актуальність дослідження обумовлюється необхідністю чіткого розуміння змісту прав дитини задля їх відмежування від суміжних правових понять.Відзначається, що за сучасних умов функціонування Української держави на порядку денному для вітчизняної правничої науки постало питання як забезпечення людських прав, так і забезпечення прав дитини.Метою роботи є висвітлення особливостей прав дитини.Акцентується увага на окремих положеннях, які мають важливе методологічне значення для сприйняття проблематики прав дитини.Права дитини тривалий час переважно не були предметом вітчизняного правничого дискурсу, зважаючи на усталене сприйняття дитини, зокрема, як об'єктів виховного впливу повнолітніх осіб (для подолання такого підходу в Україні запроваджена нова українська школа, основною ідеєю якої є забезпечити можливість вільного розвитку дитини).Відзначається, що певна непослідовність сприйняття людських прав стала чинником розуміння прав дитини як категорії, що замінює своїм змістом людські права.Людські права є тими вимогами, що ставляться не до інших осіб (фізичних чи юридичних), а саме до держави.На державі лежить обов'язок забезпечувати ці природні, невід'ємні можливості людини.При цьому, це односторонній зв'язок: людина наділена тільки правами, а держава має тільки обов'язки.Людські права не передбачають (і не можуть передбачати) обов'язки людини; обов'язки покладаються на публічну владу.Натомість права дитини передбачають наявність у дитини і певних обов'язків та, відповідно, наявність обов'язків та прав у інших суб'єктів (наприклад, батьків, опікунів, піклувальників та ін
O impacto de hedge accounting no valor da empresa: setores das comunicações, retalho e tecnologias

Field: Business, Management and Accounting (Social Sciences)

In recent decades, there has been a growing internationalization of the economy, which implies an increase in the market risk to which companies are exposed. In this sense, companies feel a growing need to manage this risk, which can be carried out through derivative instruments. For this reason, the use of derivative instruments has grown exponentially. The hedge accounting method shall be applied to the derivatives of the above, in accordance with the accounting standard in force - IFRS 9. Thus, this study aimed to understand the impact of the use of derivative instruments on the company's book value, its market value and value for the investor and to understand the extent to which there are differences between the communications, retail, and technology sectors. The evaluation of this impact was based on variables that represent the proportion of the notional value and the market value of the hedging instruments to which hedge accounting is applied and the impact of the effective and ineffective proportion of the coverage ratio. The study was based on annual reports published by companies listed on the S&P500 market in the sectors mentioned. The results obtained allow us to conclude that, in general, the accounting value of the company is affected by the effective proportion of the hedging ratio and the value of the company to the investor is affected by the proportion of the notional value of the coverage instruments to which hedge accounting is applied. The company's market value was not affected using hedge accounting. There were divergences between the sectors under study. In the communications sector, the application of hedge accounting has no impact. In the retail sector, the company's book value is affected by the effective and ineffective proportion of the coverage ratio. Finally, in the technology sector, the value of the company to the investor is affected by the proportion of the notional value of the hedging instruments to which hedge accounting is applied.
Crossover critical behaviour in the ternary liquid mixtures of ethanol, water and potassium carbonate

Field: Chemistry (Physical Sciences)

There exist two upper critical points and one lower critical point near the DCP (double critical point) and CDP (critical double point) in the ternary mixtures of ethanol, water and potassium carbonate. The DCP and CDP were avoided by changing the mass ratio of ethanol to water to reach the regions where only one upper critical point exists. In this simple region, the coexistence curves of temperature-refractive index were measured for the mass ratios of ethanol to water being 0.3699 and 0.5042 to examine the crossover critical behaviour. It was found that the crossover is nonmonotonic and consistent with Sengers' crossover theory.
Finding and Matching Communities in Social Networks Using Data Mining

Field: Computer Science (Physical Sciences)

The rapid growth in the number of users using social networks and the information that a social network requires about their users make the traditional matching systems insufficiently adept at matching users within social networks. This paper introduces the use of clustering to form communities of users and, then, uses these communities to generate matches. Forming communities within a social network helps to reduce the number of users that the matching system needs to consider, and helps to overcome other problems from which social networks suffer, such as the absence of user activities' information about a new user. The proposed system has been evaluated on a dataset obtained from an online dating website. Empirical analysis shows that accuracy of the matching process is increased using the community information.
Correlative transmission electron and soft x-ray microscopy for bridging length scales and functional properties in nanoscience and materials research

Field: Materials Science (Physical Sciences)

Transmission electron and soft x-ray microscopy have contributed significantly to our understanding of phenomena in fields ranging from biology to materials science by providing highly complementary information from the atomic level to the nano- and micrometre scale, including from structural, electronic, magnetic, and chemical perspectives. However, correlative transmission electron and soft x-ray microscopy investigations on the very same samples that take full advantage of their complementary imaging and spectroscopic capabilities are surprisingly rare. In this review, we focus on the most recent developments in combining the various types of transmission electron and soft x-ray microscopy techniques including progress in sample environment, in situ and operando techniques. Based on recent research examples ranging from nanocatalysis to functional materials and 2D materials, we highlight the unique opportunities promised by fully correlative transmission electron and soft x-ray microscopy approaches.

High-Performance Heat Sink for Hybrid Electric Vehicle Inverters

Field: Engineering (Physical Sciences)

We report a novel active heat sink (AHS) that allows high-density electronic components to operate at a stable temperature over a broad range of ambient conditions. AHS receives heat at high flux and transfers it at reduced flux to environment, coolant fluid (e.g., air or engine coolant), heat pipe, or structures. Temperature of the heat load can be controlled electronically. Target applications for AHS include thermal management of high-power inverters for hybrid electric vehicles. Depending on the configuration, AHS can handle a heat load of several hundred watts at a heat flux over 1,000 W/cm2 with a thermal resistance as low as 0.1 °C/W. AHS physics, engineering design for inverter applications, performance simulations, and initial test data are presented.
DeepAuto: A Hierarchical Deep Learning Framework for Real-Time Prediction in Cellular Networks

Field: Computer Science (Physical Sciences)

Accurate real-time forecasting of key performance indicators (KPIs) is an essential requirement for various LTE/5G radio access network (RAN) automation. However, an accurate prediction can be very challenging in large-scale cellular environments due to complex spatio-temporal dynamics, network configuration changes and unavailability of real-time network data. In this work, we introduce a reusable analytics framework that enables real-time KPI prediction using a hierarchical deep learning architecture. Our prediction approach, namely DeepAuto, stacks multiple long short-term memory (LSTM) networks horizontally to capture instantaneous, periodic and seasonal patterns in KPI time-series. It further merge with feed-forward networks to learn the impact of network configurations and other external factors. We validate the approach by predicting two important KPIs, including cell load and radio channel quality, using large-scale real network streaming measurement data from the operator. For cell load prediction, DeepAuto model showed up to 15% improvement in Root Mean Square Error (RMSE) compared to naive method of using recent measurements for short-term horizon and up to 32% improvement for longer-term prediction.

The results indicate that the active power and reactive power of bus 1are within the permitted limits (48 kW, 30 kVAR); short circuit tests meet the standard ANSI C37/UL489 and the total harmonic distortion%THD does not exceed the limits permitted by the standard IEE 929-2000.
Twin-GD: A New Twin Gated-Diode Measurement for the Interface Characterization of Ultra-Thin Gate Oxide MOSFET's with EOT Down to 1nm

Field: Engineering (Physical Sciences)

In this paper, a new twin gated-diode (T-GD) method has been greatly improved for the oxide interface characterization of MOS devices with gate oxide as thin as 1 nm (EOT). With the scaling of gate oxide thickness into 1 nm regime, reported GD measurement can not give correct measurement due to gate tunneling leakage current. Here, we provide a simple method to remove this limitation. This method has been demonstrated successfully for the ultra-thin (EOT= 10.2Aring) gate oxide nMOSFET devices. Application of the method to the PBTI effects of high-k gate dielectric devices has been demonstrated. It was found that high-K device has worse gate oxide quality, but its interface damage is less than that of control oxide
Ardc, antirestriction protein that broadens plasmid host range

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

RESUMEN: Los plásmidos, cuando se transfieren mediante conjugación, deben superar ciertos controles de entrada, como los sistemas de restricción-modificación de la célula receptora, que son responsables de distinguir entre ADN extraño o propio. Algunos plásmidos conjugativos codifican sus propias proteínas antirrestrictivas, permitiendo que los plásmidos superen estas barreras. ArdC, proteína codificada por un gen del plásmido de amplio rango de huésped R388, se requiere en las células receptoras para la conjugación de Escherichia coli a Pseudomonas putida. Hemos resuelto la estructura de ArdC, una proteína compuesta por un dominio N-terminal de unión a ADN de cadena sencilla y un dominio metaloproteasa C-terminal, aunque la actividad metaloproteasa no es necesaria para la actividad protectora del ADN. También hemos visto que no se requiere ardC para la conjugación si el sistema de R-M Tipo I se delecciona de las células receptoras de P. putida. Por lo tanto, ArdC tiene actividad antirrestricción contra el sistema HsdRMS de P. putida que amplía el rango de huéspedes del plásmido R388.
