Predicting habitual water intake from lifestyle questions.

Previous studies have used selective recall and descriptive dietary record methods, requiring considerable effort for assessing food and water intake. This study created a simplified lifestyle questionnaire to predict habitual water intake (SQW), accurately and quickly assessing the habitual water intake. We also evaluated the validity using descriptive dietary records as a cross-sectional study. First, we used crowdsourcing and machine learning to collect data, predict water intake records, and create questionnaires. We collected 305 lifestyle-related questions as predictor variables and selective recall methods for assessing water intake as an outcome variable. Random forests were used for the machine learning models because of their interpretability and accurate estimation. Random forest and single regression correlation analysis were augmented by the synthetic minority oversampling that trained the model. We separated the data by sex and evaluated our model using unseen hold-out testing data, predicting the individual and overall habitual water intake from various sources, including non-alcoholic beverages, alcohol, and food. We found a 0.60 Spearman's correlation coefficient for total water intake between the predicted and the selective recall method values, reflecting the target value to be achieved. This question set was then used for feasibility tests. The descriptive dietary record method helped to obtain a ground-truth value. We categorized the data by gender, season, and source: non-alcoholic beverages, alcohol, food, and total water intake, and the correlation was confirmed. Consequently, our results showed a Pearson's correlation coefficient of 0.50 for total water intake between the predicted and the selective recall method values. We hypothesize that dissemination of SQW can lead to better health management by easily determining the habitual water intake.

Dynamic field load testing of a horizontally curved longspan LRT Kuningan bridge using eccentric mass vibrator and experimental modal analysis

Light Rail Transit (LRT) infrastructure in Indonesia is developing at a rapid pace. The LRT challenging construction is the Kuningan-Longspan Curved bridge with a span of 148 meters and the radius of curvature R = 115 meter.

Parametric Delayed Output Feedback Control for Versatile Human-Exoskeleton Interactions During Walking and Running

This paper presents a parametric delayed output feedback controller for various types of human-exoskeleton interactions during walking or running gait. The parametric delayed-feedback controller operates reliably during various gait pattern changes, utilizing three adjustable control parameters: smoothing factor, time delay, and feedback gain. We show that various human-exoskeleton interaction torques can be generated using these three parameters, such as assistance with running or walking and different types of resistances. Feasibility tests were performed to demonstrate the efficacy of the proposed interaction controller. Hip exoskeleton assistance reduces the metabolic cost by 12.3% during running at 7 km/h compared with running without the exoskeleton. The generalizability of the controller performance was also demonstrated through various gait speed tests. Furthermore, we measured the electromyography signal data and the human lower limb joint kinematics to examine the feasibility of providing different gait resistances using different time delays. The results show that resistance with a delay of 0.3 s (Late mode) instead of a delay of 0.1 s (Early mode) is possible for walking resistance training, focusing on the hip flexors compared to the zero-torque mode.

Unsupervised image-to-image translation in multi-parametric MRI of bladder cancer

Detection of muscular invasive bladder cancer (MIBC) is critical for surgical selection of bladder cancer (BCa) patients. Currently, multi-parameter magnetic resonance imaging (mp-MRI) is the predominant approach for identifying MIBC. However, mp-MRI is still insufficient due to the presence of noise and artifacts. Our research aims to synthesize images from the existing sequences of mp-MRI to substitute missing or low signal-to-noise ratio sequences through image-to-image (I2I) translation. Using mp-MRI images of 255 BCa patients collected in our department, we here propose a one-to-many unsupervised I2I translation network with region-wise semantic enhancement to synthesize virtual samples. We introduce an improved adaptive instance normalization module to support the generator for synthesizing multi-domain images. In addition, a branch for region-wise semantic segmentation helps the generator to enhance the quality of image translation for a specific region. A semantically consistent loss is applied to maintaining the consistency between the synthesized and the input images via region-wise semantic segmentation. Experiments on the BraTS and BCa datasets indicate that our I2I translation approach outperforms several state of the art methods. Additionally, we perform clinical feasibility tests using the synthesis images. The clinicians reach a consensus between the Vesical Imaging Reporting and Data System (VI-RADS) scoring results from the synthesized and the real mp-MRI images. In addition, after the BCa training set has been expanded using the proposed generation model, the accuracy of the BCa muscular invasion classification is improved from 77.78% to 85.19%.

Experimental investigation and structural optimization prediction of a novel carbon stripper for solid-fuel chemical looping combustion

The addition of carbon stripper (CS) can effectively improve the carbon conversion efficiency in the fuel reactor of solid-fuel chemical looping combustion system. An independent CS system is constructed, and the feasibility of the system is verified through feasibility tests and reference work condition tests. The effects of important conditions on the separation performance of CS are also explored based on the experimental platform. It is found that increasing the main gas velocity and cross-flow velocity in the air reactor can effectively improve the directional separation efficiency of binary particles. On the other hand, based on the Computational Fluid Dynamics platform, the important structural factors, including baffle angle, deflector angle and deflector length of the CS, are studied for the directional separation mechanism of binary particles. The results show that a CS structure with the baffle length of 140 mm, the baffle angle of 110°, the deflector length of 40 mm, and the deflector angle of 60° exhibits good directional separation performance. In this case, the separation efficiency of quartz sand is close to 100%, and that of polyvinyl chloride (PVC) particles can reach a high value of 93.7%, demonstrating the high separation efficiency and promising application prospects of this novel CS.

Development of Ultrasound Phantom Made of Transparent Material: Feasibility of Optical Particle Image Velocimetry.

The need for ultrasound flow phantoms to validate ultrasound systems requires the development of materials that can clearly visualize the flow inside for measurement purposes. A transparent ultrasound flow phantom material composed of poly(vinyl alcohol) hydrogel (PVA-H) with dimethyl sulfoxide (DMSO) and water solution manufactured using the freezing method and mixed with quartz glass powder to exhibit scattering effects is proposed. To achieve transparency of the hydrogel phantom, the refractive index (RI) was changed to match that of the glass by modifying the PVA concentration and the ratio of DMSO to water in the solvent. The feasibility of optical particle image velocimetry (PIV) was verified by comparing an acrylic rectangular cross-section channel with a rigid wall. After the feasibility tests, an ultrasound flow phantom was fabricated to conduct ultrasound B-mode visualization and Doppler-PIV comparison. The results revealed that the PIV measured through PVA-H material exhibited 0.8% error in the measured maximum velocity compared with PIV through the acrylic material. B-mode images are similar to real tissue visualization with a limitation of a higher sound velocity, when compared with human tissue, of 1792 m/s. Doppler measurement of the phantom revealed approximately 120% and 19% overestimation of maximum and mean velocities, respectively, compared with those from PIV. The proposed material possesses the advantage of the single-phantom ability to improve the ultrasound flow phantom for validation of flow.

Feasibility analysis of a newly developed multifunctional mastication simulator

Food oral mastication is a highly complicated dynamic process which involves multiple sequential or simultaneous operations. Ethical complication and technical difficulties for oral access make in situ studies of food oral processing highly challenging and, therefore, feasible instrumental techniques are highly desirable in order to be able to conduct food oral processing research in vitro instead. In this work, a newly developed mastication simulator equipped with 3D printed teeth, controlling units, and various probes have been developed. The device is capable of simulating chewing actions by using two step motors controlling transverse and longitudinal movements. The mastication units sits inside an airtight and properly temperature controlled chamber made of aluminum alloy. The chamber has various small ports to allow the addition of artificial saliva and access of probes monitoring of the temperature, conductivity and pH of the collected saliva. Fractured food particles can be collected for size distribution analysis and to quantify the kinetics of food mastication. Conductivity and pH of the collected fluid (artificial saliva + food juice) can be measured as a function of mastication time or chewing cycles. Air inside the chamber can be collected regularly for composition analysis so that the kinetics of aroma release of a food can be monitored during mastication. Nuts and food gels have been used for feasibility tests of the device. Results demonstrate that the current design provides a feasible tool for in vitro oral mastication analysis during food oral processing.
