NASA's Sample Retrieval Lander would touch down on Mars and remain in place to receive a diverse collection of scientifically curated samples of Martian rock already collected and cached by NASA's Perseverance rover.

Biggest Lander Ever Sent to Mars

The payload mass of the lander is double that of the Perseverance rover (1,241 pounds, or 563 kilograms). The lander's hefty cargo would include a rocket, sample transfer arm, and two helicopters. Each landing leg would be roughly the size of a human adult, with the whole lander standing about as tall as a professional basketball player.

First Mars Vehicle to Carry Two Helicopters

These aerial explorers would be based on the Ingenuity Helicopter carried to the Red Planet by the Perseverance rover. They would have wheels added for agility and a small arm to grab one sample tube at a time, in case the helicopters are needed to help retrieve Mars samples left by Perseverance.

Interactions with Multiple Vehicles

The lander would interact with the Perseverance rover, the Sample Recovery Helicopters (as needed), and the Mars Ascent Vehicle in order to prepare the sample tubes for launch into orbit around Mars. The task requires many highly accurate robotic arm movements, to be performed by ESA's Sample Transfer Arm.

For most censuses, IPUMS has multiple datasets which were constructed using different sampling techniques (i.e. size/demographic of the sample population, geographic coverage level or location, or duration of the sampling period for the ACS/PRCS samples).

New rules published on May 17, 2016, under the Americans with Disabilities Act (ADA) require employers that offer wellness programs that collect employee health information to provide a notice to employees informing them what information will be collected, how it will be used, who will receive it, and what will be done to keep it confidential. The EEOC has published the sample notice below to help employers comply with the ADA:

Note: For accessibility purposes, we have used "Track Changes" to make comments along the margins of these samples. Those authored by [AF] denote explanations of formatting and [AWC] denote directions for writing and citing in APA 7.

If x has length 1, is numeric (in the sense ofis.numeric) and x >= 1, sampling viasample takes place from 1:x. Note that thisconvenience feature may lead to undesired behaviour when x isof varying length in calls such as sample(x). See the examples.

The optional prob argument can be used to give a vector ofweights for obtaining the elements of the vector being sampled. Theyneed not sum to one, but they should be non-negative and not all zero.If replace is true, Walker's alias method (Ripley, 1987) isused when there are more than 200 reasonably probable values: thisgives results incompatible with those from R < 2.2.0.

This page contains sample papers formatted in seventh edition APA Style. The sample papers show the format that authors should use to submit a manuscript for publication in a professional journal and that students should use to submit a paper to an instructor for a course assignment. You can download the Word files to use as templates and edit them as needed for the purposes of your own papers.

The following two sample papers were published in annotated form in the Publication Manual and are reproduced here as PDFs for your ease of use. The annotations draw attention to content and formatting and provide the relevant sections of the Publication Manual (7th ed.) to consult for more information.

These sample papers demonstrate APA Style formatting standards for different student paper types. Students may write the same types of papers as professional authors (e.g., quantitative studies, literature reviews) or other types of papers for course assignments (e.g., reaction or response papers, discussion posts), dissertations, and theses.

Example 3

The proposed research will involve a small sample (less than 20 participants) recruited from clinical facilities in the New York City area with Williams syndrome. This rare craniofacial disorder is associated with distinguishing facial features. Even with the removal of all identifiers, we believe that it would be difficult if not impossible to protect the identities of subjects given the physical characteristics of subjects, the type of clinical data (including imaging) that we will be collecting, and the relatively restricted area from which we are recruiting subjects. Therefore, we are not planning to share the data.

Almost half the exam time will be devoted to stand-alone multiple-choice questions with between four and six answer options and one or more correct answers. Initially, many of these questions will closely resemble Multistate Bar Examination (MBE) questions; this will ensure stability between scores for the current and NextGen bar exams. In future administrations, the variety of multiple-choice question types will increase. This sample set of questions includes both new question types and questions in the current MBE format. Note that some multiple-choice questions may also appear in the integrated question sets and longer writing tasks.

NextGen Bar Exam Sample Questions are protected under US copyright laws. These sample questions are for your personal use only. The questions and answers may not be reproduced or disseminated, and commercial use is prohibited without a license from NCBE.

(logical) When TRUE, call CmdStan with argument"algorithm=fixed_param". The default is FALSE. The fixed parametersampler generates a new sample without changing the current state of theMarkov chain; only generated quantities may change. This can be usefulwhen, for example, trying to generate pseudo-data using the generatedquantities block. If the parameters block is empty then usingfixed_param=TRUE is mandatory. When fixed_param=TRUE the chains andparallel_chains arguments will be set to 1.

(character vector) The diagnostics to automatically checkand warn about after sampling. Setting this to an empty string "" orNULL can be used to prevent CmdStanR from automatically reading in thesampler diagnostics from CSV if you wish to manually read in the resultsand validate them yourself, for example using read_cmdstan_csv(). Thecurrently available diagnostics are "divergences", "treedepth",and "ebfmi" (the default is to check all of them).

These diagnostics are also available after fitting. The$sampler_diagnostics() method providesaccess the diagnostic values for each iteration and the$diagnostic_summary() method providessummaries of the diagnostics and can regenerate the warning messages.

This sample ballot tool includes: All candidates in every upcoming election occurring within the 100 most-populated cities in the U.S., plus all federal and statewide elections, including ballot measures, nationwide. Additional local elections and ballot measures may also be included. Tribal elections are not included. Territorial elections are included.

Thank you for using Ballotpedia's sample ballot tool. We test the tool on an ongoing basis for accuracy. The note below discusses how we do that, and how you can help. (Click here to read about the Eight Quality Benchmarks for a Sample Ballot Lookup Tool.)

Ballotpedia regularly tests our sample ballot's accuracy by looking up addresses on both it and the official sample ballot and comparing the lookup results from both tools. We strive for our sample ballot tool to be 100% accurate. This means that, for offices within our coverage scope, a person's sample ballot results should include every election that will appear on their actual ballot. It should also include every candidate running in those elections, except write-ins. Finally, it should not contain errors such as misspelled names, inaccurate incumbency labels, or incorrect political party affiliations.

Zephyr also provides a variety of Samples and Demos, including very simple Basic Samples.These samples are a good starting point for understanding how to put together your own application.However, Zephyr samples and applications are not tested and verified to work with the nRF Connect SDK releases.

All samples in the nRF Connect SDK use Fatal error handler library and are configured to perform a system reset if a fatal error occurs.This behavior is different from how fatal errors are handled in the Zephyr samples.You can change the default behavior by updating the configuration option CONFIG_RESET_ON_FATAL_ERROR.

When data sampling is enabled, the query is not performed on all the data, but only on a certain fraction of data (sample). For example, if you need to calculate statistics for all the visits, it is enough to execute the query on the 1/10 fraction of all the visits and then multiply the result by 10.

In this example, the query is executed on a sample from 0.1 (10%) of data. Values of aggregate functions are not corrected automatically, so to get an approximate result, the value count() is manually multiplied by 10.

When using the SAMPLE n clause, you do not know which relative percent of data was processed. So you do not know the coefficient the aggregate functions should be multiplied by. Use the _sample_factor virtual column to get the approximate result.

The _sample_factor column contains relative coefficients that are calculated dynamically. This column is created automatically when you create a table with the specified sampling key. The usage examples of the _sample_factor column are shown below.

This will bring up a selector list of analyses. A particular dialog can also be run directly from the command line, if you know its name (can be discovered by browsing piface.jar with a zip file utility). For example, the two-sample t-test dialog may be run using e24fc04721
