title: Enhanced Secondary-Electron Detection of Single Ion Implants in Silicon Through Thin SiO2 Layers

description: The experimental data in this spreadsheet was used to generate the results reported in the paper "Enhanced Secondary-Electron Detection of Single Ion Implants in Silicon Through Thin SiO2 Layers."

Deterministic placement of single dopants is essential for scalable quantum devices based on group-V donors in silicon. We demonstrate a non-destructive, high-efficiency method for detecting individual ion implantation events using secondary electrons (SEs) in a focused ion beam system. Using low-energy Sb ions implanted into un-doped silicon, we achieve up to 98 ± 1% single-ion detection efficiency (DE). We find introducing thin, controlled SiO2 capping layers enhances SE yield, consistent with increased electron mean free path in the oxide, while maintaining successful ion deposition in the underlying silicon substrate. Our approach provides a robust and scalable route to precise donor placement and extends deterministic implantation strategies toa broad range of material systems and quantum device architectures.

title: 2021 NIST Speaker Recognition Evaluation Development and Test Set

description: <h3>Introduction</h3>
<p>2021 NIST Speaker Recognition Evaluation Test Set (LDC2025S11) was developed by the Linguistic Data Consortium (LDC) and NIST (National Institute of Standards and Technology). It contains approximately 447 hours of Cantonese, Mandarin, and English converstaional telephone speech (CTS), audio from video (AfV), and image data for development and test, along with answer keys, enrollment, trial files and documentation from the NIST-sponsored <a href="https://www.nist.gov/itl/iad/mig/nist-2021-speaker-recognition-evaluation-sre21">2021 Speaker Recognition Evaluation (SRE)</a>.</p>
<p>The ongoing series of SRE evaluations conducted by NIST are intended to be of interest to researchers working on the general problem of text independent speaker recognition. To this end the evaluations are designed to be simple, to focus on core technology issues, to be fully supported and to be accessible to those wishing to participate.</p>
<p>The SRE task is speaker detection, that is, to determine whether a specified target speaker was speaking during a segment of speech. SRE21 focused on telephone speech and audio from video and included close-up images of participants. The evaluation also featured cross-lingual trials, that is, enrollment and test segments spoken in different languages. Further information about the evaluation is contained in the SRE21 evaluation plan included in this release.</p>
<h3>Data</h3>
<p>The data was drawn from the WeCanTalk corpus collected by LDC in which speakers called friends or relatives who agreed to record their telephone conversations lasting between 8-10 minutes. Subjects contributed multiple conversational telephone speech recordings and audio recordings in which they were talking, plus a single selfie image. Recordings were manually audited to verify speaker, language, and quality.</p>
<p>The corpus contains approximately 355 hours of CTS audio, 53 hours of AfV segments, and 39 hours of video clips and 202 selfie images.</p>
<p>The CTS data is presented as sphere files in 8kHz A-law format, AfV segments are presented as 16 kHz FLAC-compressed MS-WAV files, videos are presented in mp4 format. and images are presented in JPG format.</p>
<p>In addition to the development and evaluation data, this corpus also contains answer keys, enrollment, trial files and documentation.</p>
<h3>Updates</h3>

title: HIFLD OPEN Wrecks and Obstructions

description: Shipwrecks and obstructions in the ocean have long been a hazard to navigation and construction, and points of interest to archaeologists, recreational divers, fishermen, educators, and explorers. Locating hazardous wrecks and obstructions is part of the ongoing NOAA charting process. The exact position of many wrecks is difficult to determine because of changes in the environment, varied survey methods, and human error. Some wrecks are intentionally placed in the ocean to serve as artificial reefs or for disposal. Others pose a health and environmental threat from their cargo. Ownership and control over wrecks and obstructions is governed by a collection of state and federal regulations, the Abandoned Shipwreck Act, National Historic Preservation Act, and National Marine Sanctuaries Act.<br><br>These data are a synthesis of two sources—the NOAA Office of Coast Survey’s 2016 Automated Wreck and Obstruction Information System (AWOIS), and NOAA Electronic Navigational Charts (ENC). Not included were those records that were clearly identified as natural features such as rocks, shoals, and trees. Features are recorded as either a wreck, wreck area, obstruction, or unknown.

title: Kinder Houston Area Survey, 2009-2018: Successive Representative Samples of Houston Residents

description: The Kinder Houston Area Survey is a longitudinal study that began in May 1982 after Houston, Texas, recovered from the recession of the mid-1980s. The overall purpose of this research was to measure systematically the public responses to the new economic, educational, and environmental challenges, and to make the findings of this continuing project readily available to civic and business leaders, to the general public, and to research scholars. 

This restricted-use dataset contains all the responses from the successive representative samples of Houston residents from 2009 through 2018. These are the data that enabled the project to analyze continuity and change among area residents over the past 9 years. Altogether, the survey reached a total of 6,387 Anglos, 3,704 African Americans, 4,384 Hispanics, 1,101 Asians, and 275 others. 

Conducted during February and March of each year, the interviews measured perspectives on the local and national economy, on poverty programs, inter-ethnic relationships. Also captured were respondents' beliefs about discrimination and affirmative action, education, crime, health care, taxation, and community service, as well as their assessments of downtown development, mobility and transit, land-use controls and environmental concerns, and their attitudes toward abortion, homosexuality, and other aspects of the social agenda. Also recorded were religious and political orientations, as well as an array of demographic and immigration characteristics, socioeconomic indicators, and family structures. 

In addition, the data record the geographic information of each respondent, which enables researchers to connect the respondents' perceptions and experiences with information on the neighborhoods in which they live, thereby adding a contextual dimension to analyses of the factors that account for individual differences in attitudes and beliefs.
