title: Dick Whittington Photography Collection, 1924-1987

description: The "Dick" Whittington Studio was the largest and finest photography studio in the Los Angeles area from 1924 to 1987. Specializing in commercial photography, the Whittington Studio took photographs for nearly every major business and organization in Los Angeles; in so doing, they documented the growth and commercial development of Los Angeles. Clients included Max Factor, the Broadway, Bullock's, and May Co. department stores, the California Fruit Growers Association, Signal Oil, Shell Oil, Union Oil, Van de Kamp's bakeries, Forest Lawn, Sparkletts Water, CBS, Don Lee Television, Goodyear Tire and Rubber, real estate developers, construction companies, automobile, aircraft, and railroad companies, and drive-in theaters. Another notable client was the University of Southern California, which contracted with the Whittington Studios for coverage of athletic and other events. The collection consists primarily of roughly 500,000 negatives; the rest are photoprints. Supporters The collection is only partially digitized, but thanks to the generous help of the National Endowment for the Humanities (NEH) and the National Historical Publications and Records Commission (NHPRC), the USC Libraries has digitized 76,645 at-risk negatives in obsolete formats from the 1920s to 1940s.

description: Rhodiola yunnanensis(Crassulaceae) is an endemic medicinal plant distributed in the Hengduan Mountains of southwestern China. Here, we present a high-quality, near telomere-to-telomere chromosome-level genome assembly of R. yunnanensisgenerated using Oxford Nanopore long-read sequencing and Hi-C scaffolding. The assembled genome spans 643.28 Mb with a contig N50 of 51.92 Mb, and 98.46% of the sequence was anchored to 11 pseudochromosomes, among which eight are completely gap-free. Benchmark analyses showed a BUSCO completeness of 97.46%, while the LTR Assembly Index (LAI) score reached 20.50, both supporting a gold-standard level of assembly quality. Telomeric repeat motifs were detected at both ends of 10 pseudochromosomes, and centromeric regions were identified on all 11 chromosomes. We predicted 36,495 protein-coding genes, 94.16% of which were functionally annotated, together with 1,643 transcription factors and 6,429 non-coding RNAs.This high-quality genome provides a valuable resource for studying alpine adaptation, specialized metabolite biosynthesis, and evolutionary diversification in Rhodiolaand other high-altitude plants.

title: Real-Time Inter-Vehicle Distance Estimation and Multi-Vehicle Detection Using FMCW Radar with Corner Reflectors and Reflective Metal Sheets

description: This dataset supports the research study titled "Blind-Spot Vehicle Distance Estimation Using High-Frequency FMCW Radar and Passive Metal Reflectors", conducted since April 2025.
The study proposes a novel method for estimating inter-vehicle distances when preceding vehicles are located in blind-spot environments. The method combines a 24 GHz high-frequency FMCW radar with passive metal sheets and triangular corner reflectors to enhance radar signal reflection and detection capabilities. Specifically, the system exploits the radiation directivity of the radar, the boundary reflection characteristics of passive metal sheets, and the high radar cross-section (RCS) gain of corner reflectors.

By analyzing the reflected signals based on the transmission angle and discrete Fourier transform (DFT) results, the proposed method enables the detection of multiple preceding vehicles even under non-line-of-sight (NLOS) conditions where conventional sensors such as cameras, LiDAR, or standard millimeter-wave radars fail. Experimental validation was performed using three vehicles, including the radar-equipped one, with variable inter-vehicle distances and radar transmission angles. The method achieved an average distance estimation error of approximately 0.36 m under blind-spot conditions.

This research demonstrates that accurate vehicle distance estimation can be achieved even in NLOS environments, contributing to the advancement of environmental perception technologies for next-generation mobility systems. Furthermore, the proposed approach has potential applications in improving road safety by preventing chain-reaction collisions, particularly those caused by delayed human responses or operational errors among elderly drivers.

title: Joint space calibration data for dVRK Si

description: # Data for dVRK Si tool calibration

Four joints (Joint 3, 4, 5 and 6) are calibrated. All data is .csv files. Each joint has 15 groups of data used for training and validating during training, stored in the folder "Si_Joint?". 

 





Testing set is stored in the folder "Test_dataset", with Joint index in their file names.



 

For both training dataset and testing set, each file has two columns. (If it contains 3 columns, ignore the first column.) The first one is the commands given to the robot, which is the output of the network. The second one is the real joint angle measured corrosponding to the commands, which is the input of the network.

 

All data in this data set is collected with the same permanent cautery spatula.

 

Note: This is the raw dataset. Data cleanning is probably needed based on the usage.

Testing set is stored in the folder "Test_dataset", with Joint index in their file names.



 

For both training dataset and testing set, each file has two columns. (If it contains 3 columns, ignore the first column.) The first one is the commands given to the robot, which is the output of the network. The second one is the real joint angle measured corrosponding to the commands, which is the input of the network.

 

All data in this data set is collected with the same permanent cautery spatula.

 

Note: This is the raw dataset. Data cleanning is probably needed based on the usage.
