This research examines whether transportation network companies (TNCs), such as Uber and Lyft, live up to their stated vision of reducing congestion in major cities. Existing has produced conflicting results been hampered by a lack data. Using data scraped from the application programming interfaces two TNCs, combined with observed travel time data, we find that contrary vision, TNCs are biggest contributor growing traffic San Francisco. Between 2010 2016, weekday vehicle hours delay...

Abstract Transportation network companies (TNCs), such as Uber and Lyft, have been hypothesized to both complement compete with public transit. Existing research on the topic is limited by a lack of detailed data timing location TNC trips. This study overcomes that limitation using scraped from Application Programming Interfaces two TNCs, combined Automated Passenger Count transit use other supporting data. Using panel model change in bus ridership San Francisco between 2010 2015, confirming...

Results of the analyses occupational and environmental samples are frequently reported as “less than a specified value,” practice followed by many analytical laboratories. A left-censored distribution occurs when laboratories do not report results that fall below their limits detection or quantification. Approximately 37% household interior dust lead loadings collected in large-scale, multisite, longitudinal study lead-based paint hazard controls were to be “method limit.” These unreported...

Using probe vehicles to collect real-time traffic information is considered an efficient method in real-world applications. How determine the minimum number of required for accurate estimate link travel time a question increasing interest. Although it usually assumed that normally distributed, shown, on basis simulation results, sometimes this not true. A heuristic determining developed accommodate situation. In addition, impact volume vehicle discussed.

There has been a lack of socioeconomic status (SES) disparity analysis on women in China with only one child, the family planning target population. In 2008, National Research Institute for Family Planning conducted study investigating relationship between SES and fertility intentions among 17,093 who already had child. A questionnaire was used to collect information intentions, logistic regression models were estimate odds ratios 95% CIs according SES. Compared female farmers, other...

Recent research in dynamic convolution shows substantial performance boost for efficient CNNs, due to the adaptive aggregation of K static kernels. It has two limitations: (a) it increases number convolutional weights by K-times, and (b) joint optimization attention kernels is challenging. In this paper, we revisit from a new perspective matrix decomposition reveal key issue that applies over channel groups after projecting into higher dimensional latent space. To address issue, propose...

796 Background: Sacituzumab tirumotecan (sac-TMT; also known as MK-2870/SKB264) is a TROP2 targeting ADC with hydrolytically cleavable linker and topoisomerase I inhibitor payload, KL610023 (average drug-to-antibody ratio, 7.4). In patients (pts) urothelial carcinoma (UC), treatment the anti-TROP2 sacituzumab govitecan led to treatment-related grade ≥3 neutropenia in 35% of pts febrile 10%. Cohort 9 MK-2870-001 (KL264-01; NCT04152499) evaluated sac-TMT monotherapy unresectable, locally...

(Abstracted from J Clin Oncol 2017;35:2535–2541) Endometrial cancer (EC) identified at an early stage is successfully treated in a majority of patients with surgery or without radiotherapy chemotherapy. For advanced disease, however, the prognosis poor; 5-year survival rates are less than 50% lymph node metastases and 20% those peritoneal distant metastases.

3D building models are important for many applications related to human activities in urban environments. However, due the high complexity of structures, it is still difficult automatically reconstruct with accurate geometric description and semantic information. To simplify this problem, article proposes a novel approach decompose compound buildings symmetric roofs into primitives by exploiting local symmetry contained structure. In approach, proposed decomposition allows overlapping...

The characteristics of traffic flow under various conditions have been studied by many. Particularly, researchers use the concept phases to distinguish conditions. In this study, a data-clustering methodology is developed define using continuous data obtained through detectors. Such provide rich information on characteristics. It shown that between two clustering variables, density has more significant impact results than speed. fundamental relationships parameters are then analyzed based...

A novel method for registering imagery with Light Detection And Ranging (LiDAR) data is proposed. It based on the phenomenon that back-projection of LiDAR point cloud an object should be located within boundary in image. Using this inherent geometrical constraint, registration parameters computation both sets only requires clouds several objects and their corresponding boundaries The proposed comprises four steps: extraction, computation. There are not any limitations spectral properties...
