Anna: A Dapper Open-Domain Dialogue Agent Based on a Joint Attention Network

We constructed a high-quality open-domain dialogue generation model called Anna that is composed of a hierarchical self-attention network with multiple convolution (cid:12)lters and a topic-augmented network. During daily conversations, humans typically respond by understanding a dialogue history and assembling their knowledge regarding the topic. However, existing dialogue generation models are weak at capturing the dependencies among words or utterances, resulting in an insu(cid:14)cient understanding of context and the generation of irrelevant responses. Previous works have largely ignored topic information modeling in multi-turn dialogue, making responses overly generic. Although pre-training using large-scale transformer models has recently resulted in enhanced performance, large parameter sizes complicate such models. Anna e(cid:11)ectively captures contextual dependencies and assigns greater weight to important words and utterances to compute context representations. We incorporate topic information into our model as prior knowledge to synthesize topic representations. Two types of representations jointly determine the probability distributions of responses, which e(cid:11)ectively simulates how people behave in real conversations. Empirical studies on both Chinese and English corpora demonstrate that Anna outperforms baseline models in terms of response quality, parameter size and decoding speed.
Automatic Misinformation Detection About COVID-19 in Brazilian Portuguese WhatsApp Messages

During the coronavirus pandemic, the problem of misinformation arose once again, quite intensely, through social networks. In Brazil, one of the primary sources of misinformation is the messaging application WhatsApp. However, due to WhatsApp's private messaging nature, there still few methods of misinformation detection developed specifically for this platform. In this context, the automatic misinformation detection (MID) about COVID-19 in Brazilian Portuguese WhatsApp messages becomes a crucial challenge. In this work, we present the COVID-19.BR, a data set of WhatsApp messages about coronavirus in Brazilian Portuguese, collected from Brazilian public groups and manually labeled. Then, we are investigating different machine learning methods in order to build an efficient MID for WhatsApp messages. So far, our best result achieved an F1 score of 0.774 due to the predominance of short texts. However, when texts with less than 50 words are filtered, the F1 score rises to 0.85.
PRIMARY STAGE OF PAKIS-STEM-BLOCK SYSTEM AS THERMAL PROTECTIVE TO FLAT BARE CONCRETE ROOFTOP IN TROPICAL CLIMATE OF SURABAYA

In the era of global warming and increasing urban heat island condition, flat concrete deck on shop-houses may be less sustainable to handle the excessive solar heat radiation impacts on the roof surfaces. Innovative alternative roofing system is needed to manage heat radiation that will lead to sustainable factors likes energy savings, less energy body used on the roofing materials, and provide comprehensive environmental friendly roof system. This paper discusses about particular environmental friendly materials such as “Pakis-Stem Blocks” system is a good thermal resistant to absorb the solar sun heat and provide natural cooling through convective-wind without adding substantial loads to the roof structures. “Pakis-stem blocks” are easier, cheaper and more valuable than other sub-structure roofing materials as thermal resistant layer on flat bare concrete deck besides green roofing systems.
A deadbeat current controller for field oriented induction motor drives

Accurate stator current control is essential in high performance field orientation-controlled induction motor drives. Any current error degrades the drive's performance in the same way as an incorrectly tuned field orientation. This paper presents an efficient current control scheme that can achieve high accuracy and a fast dynamic response. This scheme uses voltage decoupling and deadbeat control loops. The decoupling controller provides the voltage needed to oppose the motor's back EMF. The deadbeat controller reduces the current error as fast as possible and stabilizes the system. The control law does not require knowledge of the rotor flux and is independent of the field orientation control tuning. Good static and dynamic performances were obtained in both the simulation and experimental verifications. Because the motor leakage inductance and resistance information were required for this control method, the influence of the estimation errors for these parameters was also investigated. The results show that the leakage inductance model error might cause a current ripple. However, this parameter can be tuned to its correct value easily by inspecting the current response.
Some characteristics of a human operator

The paper discusses experimental findings which aid an understanding of the basic limitations of a human operator as an element in a servo system. It is shown how experiments on threshold effects can guide the choice of both display magnification and gear ratio. At least 2 sec appears to be required to develop the maximum perceptual acuity, but a time greater than this is usually needed in accurately setting a control for full confidence in accuracy to develop. The mechanisms of muscular movements are discussed. Reciprocatingrnovements can be performed at higher rates than circular movements, although the latter are less fatiguing. Measurements of the mechanical efficiency of man may be worth applying under conditions of heavy work. The conditions of tracking are shown to resemble multiple-choice reaction-time experiments, with a lag between stimulus and response that is strictly indeterminable, but which is generally of the order of 0.3 sec. Discontinuity in the operator is demonstrated by the inability to halt a reacting movement within 0.2 sec of its start. In practical design, the advantages are stressed of incorporating the maximum possible display magnification; of abolishing any striction in the control, possibly by using two hands; of using high rates of turning; and of introducing as much inertia as the operator can manage. The paper concludes with a note on the acquisition of skill in tracking, particularly stressing the need for simple training aids which isolate the individual stimulus-response elements, and which allow accurate scoring and control of difficulty in the task facing the operator.
An Interdisciplinary Agent-based Evacuation Model: Integrating Natural Environment, Built environment, and Social System for Community Preparedness and Resilience

Abstract. Previous tsunami evacuation simulations have mostly been based on arbitrary assumptions or inputs adapted from non-emergency situations, but a few studies have used empirical behavior data. This study bridges this gap by integrating empirical decision data from local evacuation expectations surveys and evacuation drills into an agent-based model of evacuation behavior for a Cascadia Subduction Zone community. The model also considers the impacts of liquefaction and landslides from the earthquake on tsunami evacuation. Furthermore, we integrate the slope-speed component from Least-cost-distance to build the simulation model that better represents the complex nature of evacuations. The simulation results indicate that milling time and evacuation participation rate have significant non-linear impacts on tsunami mortality estimates. When people walk faster than 1 m/s, evacuation by foot is more effective because it avoids traffic congestion when driving. We also find that evacuation results are more sensitive to walking speed, milling time, evacuation participation, and choosing the closest safe location than to other behavioral variables. Minimum tsunami mortality results from maximizing the evacuation participation rate, minimizing milling time, and choosing the closest safe destination outside of the inundation zone. This study's comparison of the agent-based model and BtW model finds consistency between the two models' results. By integrating the natural system, built environment, and social system, this interdisciplinary model incorporates substantial aspects of the real world into the multi-hazard agent-based platform. This model provides a unique opportunity for local authorities to prioritize their resources for hazard education, community disaster preparedness, and resilience plans.
Evaluation of the Impact of Different Doses of Curcuma longa L. on Antioxidant Capacity: A Randomized, Double-Blind, Crossover Pilot Trial

Curcumin is a bioactive compound derived from Curcuma longa L. root, extensively studied due to its antioxidant and anti-inflammatory properties. This study evaluates the effects of different doses of powdered C. longa root on antioxidant capacity in healthy men. In a pilot randomized, double-blinded, crossover experiment, we acutely administered a low dose (1.5 g, LCG), moderate dose (3.0 g, MCG), and high dose (6.0 g, HCG) of C. longa to nine healthy men. There were no differences in plasma curcumin levels (p = 0.593) and antioxidant capacity (p = 0.473) for time × group interactions. Plasma curcumin levels increased in all groups after 20 and 90 min of C. longa intake (p < 0.05). HCG had a lower postprandial incremental area under the antioxidant capacity curve than LCG or MCG (p < 0.01). A low dose of C. longa increased the antioxidant capacity in healthy men. However, plasma curcumin levels were not dose dependently affected.
Study on the Radial Sectional Velocity Distribution and Wall Shear Stress Associated With Carotid Artery Stenosis

BackgroundAtherosclerosis is an important cause of cardiovascular disease. The wall shear stress (WSS) is one of the key factors of plaque formation and dislodgement. Currently, WSS estimation is based on measurement of the blood velocity gradient. However, due to the lack of flow field measurements in carotid stenosis vessels, the two distribution forms (parabolic and non-parabolic) commonly considered in numerical simulations could cause WSS estimates to differ by more than 40%, which could seriously affect the accuracy of mechanical analysis. MethodsThis study was the first to apply 3D printing technology to create an experimental model of real-structure carotid arteries. Microparticle image velocimetry (micro-PIV) was adopted to comprehensively measure blood velocity field data at the stenosis location, providing experimental validation of numerical simulation (Fluent; finite volume method) results. Then, the flow field was simulated at a normal human heart rate (45-120 beats per minute). ResultsThis study revealed that when blood flowed across the carotid artery stenosis location, the velocity distribution was not parabolic but rather a plateau-shaped distribution, with a similar flow velocity in the central area (more than 65% of the total flow path). The WSS values calculated based on a parabolic velocity distribution and the maximum velocity were nearly 60% lower.ConclusionThis study provides a reliable method for WSS determination to better understand the vascular stenosis location and facilitate flow and shear force field research. In the future, it is necessary to carry out in-depth research on the relationship between the plaque shape, flow field distribution and WSS, and amendments to the calculated WSS for clinical stenosis should be proposed.

Finite element based simulations are used to confirm design presses and show less than 7% error in parametric design that is acceptable for simple primary design. (4 pages)
A 60‐GHz single‐pole‐single‐throw switch in 65‐nm bulk CMOS

A single‐pole‐single‐throw (SPST) switch in a π‐network topology is designed in a 1.2‐V 65‐nm bulk CMOS RF process for millimeter‐wave applications in the 60‐GHz band from 57 to 66 GHz. The SPST switch with an active chip area of only 96 μm × 140 μm achieves the measured 11‐dB return loss, 1.6‐dB insertion loss, and 27.9‐dB isolation at 60 GHz. The SPST switch also shows the simulated power‐handling capability of 11.4 dBm and switching speed of 1 ns at 60 GHz. These results clearly demonstrate that the SPST switch in CMOS rivals the performance of SPST switches in GaAs and therefore has potential to be used in highly‐integrated 60‐GHz CMOS radios. © 2011 Wiley Periodicals, Inc.

Unlike Brief Inhibition of Microglia Proliferation after Spinal Cord Injury, Long-Term Treatment Does Not Improve Motor Recovery

Microglia are major players in scar formation after an injury to the spinal cord. Microglia proliferation, differentiation, and survival are regulated by the colony-stimulating factor 1 (CSF1). Complete microglia elimination using CSF1 receptor (CSF1R) inhibitors worsens motor function recovery after spinal injury (SCI). Conversely, a 1-week oral treatment with GW2580, a CSF1R inhibitor that only inhibits microglia proliferation, promotes motor recovery. Here, we investigate whether prolonged GW2580 treatment further increases beneficial effects on locomotion after SCI. We thus assessed the effect of a 6-week GW2580 oral treatment after lateral hemisection of the spinal cord on functional recovery and its outcome on tissue and cellular responses in adult mice. Long-term depletion of microglia proliferation after SCI failed to improve motor recovery and had no effect on tissue reorganization, as revealed by ex vivo diffusion-weighted magnetic resonance imaging. Six weeks after SCI, GW2580 treatment decreased microglial reactivity and increased astrocytic reactivity. We thus demonstrate that increasing the duration of GW2580 treatment is not beneficial for motor recovery after SCI.
On stationary linear time-varying systems

A comprehensive review of representations of linear timevarying systems is given, both in the time and in frequency domains. Subsequently a definition is given of a stationary deterministic signal. Based on this definition the notion of stationary systems is introduced. These systems have the useful property that the spectral relation between input and output has a simpler form than the corresponding relation for arbitrary time-varying systems. It is shown that causality puts rather severe constraints on the frequency mappings that can be realized by stationary linear systems. An extension of the theory of linear time-varying systems to the case of discrete-time and hybrid systems (analog input, digital output, or vice versa) is discussed. Examples of stationary systems are given, such as a decimator, a periodic sampler, and a bilinear A/D converter. Also, a recently proposed generalized sampling method is analyzed by means of the concepts discussed in this paper.
On-chip voltage noise monitor for measuring voltage bounce in power supply lines using a digital tester

With increasing interconnect densities, voltage bounce noise in power supply lines is becoming an important problem. In this paper, we describe a method to measure voltage bounce in a power supply line on a chip. We use a voltage comparator circuit to make the output a digital value. We connect this circuit in series to output the results with less pins.
Extended-Boost $Z$ -Source Inverters

The Z-source inverter has gained popularity as a single-stage buck-boost inverter topology among many researchers. However, its boosting capability could be limited, and therefore, it may not be suitable for some applications requiring very high boost demand of cascading other dc-dc boost converters. This could lose the efficiency and demand more sensing for controlling the added new stages. This paper is proposing a new family of extended-boost quasi Z -source inverter (ZSI) to fill the research gap left in the development of ZSI. These new topologies can be operated with same modulation methods that were developed for original ZSI. Also, they have the same number of active switches as original ZSI preserving the single-stage nature of ZSI. Proposed topologies are analyzed in the steady state and their performances are validated using simulated results obtained in MATLAB/Simulink. Furthermore, they are experimentally validated with results obtained from a prototype developed in the laboratory.

Fiber optic sensor reliability issues in structural health monitoring

Reliability is an important aspect of any sensor, and especially in terms of long term monitoring of structures. Some issues pertaining to the reliability of optical fiber sensors in civil structures are discussed in this article. The strength and fatigue properties of optical fibers influence their performance, and life span. Lessons learnt from the reliability of optical fibers in the telecommunication industry are useful for assessment of reliability in optical fiber sensors. However, optical fiber sensors go through additional manufacturing steps, handling processes, and in general operate under environmental conditions and stress levels different from the telecommunication lines. In general, optical fiber sensors in structures are subjected to fatigue loading under high stresses. Other reliability concerns pertain to the effects of the packaging, installation issues at the construction site. These issues along with some of the results acquired from fatigue tests on fiber optic Bragg gratings and long gauge interferometric sensors are discussed in this article.
Impacts of the measurement equation modification of the adaptive Kalman filter on joint polarization and laser phase noise tracking

Kalman filtering (KF) has good potential in fast rotation of state of polarization (RSOP) tracking. Different measurement equations cause the diverse RSOP tracking performances. We compare the conventional KF (CKF) and the modified KF (MKF), which have different measurement equations. Semi-theoretical analysis indicates the lower conditional variances of measurement residuals and process noise of MKF. Compared with CKF, the MKF has> 3 dB optical signal-to-noise ratio (OSNR) improvement at the 10 MHz scrambling rate in simulation. For MKF, more significant tracking speed improvement exists for lower OSNR. MKF can be smoothly combined with an adaptive algorithm, which outperforms adaptive CKF throughout the simulations.
Infant Size at 8 Months of Age: Relationship to Maternal Use of Alcohol, Nicotine, and Caffeine During Pregnancy

To examine the relationship of maternal alcohol consumption, caffeine use, and smoking to infant size at 8 months of age, a follow-up cohort of 453 infants was examined at birth and again at their 8-month birthday. Even after adjustment for other relevant variables, maternal alcohol use during early pregnancy (average ounces of absolute alcohol by self-report) was significantly related to infant weight and length at 8 months of age but not as strongly related to head circumference. Maternal smoking and caffeine use during pregnancy were not significantly related to infant size at 8 months, although nicotine use had been highly related to the birth size in this sample. Maternal use of marijuana was significantly and negatively related to infant length at 8 months of age, but not to weight or head circumference. The magnitude of the growth retardation is smaller at 8 months than at birth in this sample of infants whose mothers are primarily white, married, and well-educated, and who report a variety of alcohol use patterns. Significance was tested using multiple regression analyses that adjusted for the effects of nicotine use, caffeine use, birth order, maternal height, and gestational age as well as sex and age of infant at examination.
Structural Health Monitoring of Delaware's Indian River Inlet Bridge: Year One Update

Construction of the new Indian River Inlet Bridge (IRIB) in Delaware was completed in 2012 and the bridge opened in time for the heavy summer beach resort traffic. A comprehensive Structural Health Monitoring (SHM) system was installed on the bridge during construction. The fiber-optic-based system includes more than 140 sensors to measure strain, acceleration, tilt, displacement, chlorides, and wind speed and direction on the bridge. Since the bridge opened, data has been collected automatically. Three controlled load tests have been conducted that will provide baseline data on the bridge response for the future. The test data has also been used to develop and calibrate live load models of the bridge.
How to Quantify Quality Architectural Design from the Aspect of Building Maintenance

Building construction is accused of causing environmental problems. Energy use in buildings accounts for about half of the total primary energy use in Hong Kong. There is an increasing demand for building sector to reduce energy consumption in the lifetime of buildings. Carbon dioxide is released during the processes of construction, operation and demolition of buildings. Buildings have to be well maintained after completion for efficient operation and optimal use. Most of the maintenance problems in buildings are latent defects relating to faulty design. Quantifying the quality of building design based on the need and frequency for future maintenance can reduce the environmental impacts of building construction. Construction Industry Council in United Kingdom developed an assessment system, Design Quality Indicator, to quantify the “Functionality”, “Build Quality” and “Impact” of building design, and feedback to designers. This paper outlines a research framework necessary for the development of an assessment tool based on the concept of Design Quality Indicator to quantify sustainable building design aiming at reducing maintenance work for local application.
Teleoperating a compliance task

In teleoperation, it is very important to have salient cooperation between the human operator and the control mechanism equipped on the remote manipulator. The cooperation becomes especially crucial when the teleoperation system is used to execute compliance tasks in which simultaneous control of both position and force may be demanded and inevitable contact with environments is encountered. In this paper, we focus on the issues of planning, execution, and coordination between the human operator and the remote controller in teleoperating a compliance task. In addition, we are also interested in how the intelligence in planning and control to be distributed between them according to the specific characteristics of a given compliance task. For the study, a VR-based (Virtual Reality) telerobotic system for compliance tasks is developed. The telerobotic system provides both haptic and visual information, and possesses a remote intelligence controller, capable of compliance control. Experiments based on various types of compliance tasks are performed for the investigation.
