Gait Speed and Survival in Older Adults
Gait speed was calculated for each participant using distance in meters and time in seconds. All studies used instructions to walk at usual pace and from a standing start. The walk distance varied from 8 ft to 6 m. For 8 ft, we converted to 4-m gait speed by formula.24 (link) For 6 m, we created a conversion formula (4-m speed=−0.0341 + (6-mspeed)×0.9816 withR2=0.93, based on a cohort of 61 individuals with concurrent 4- and 6-m walks). For 15 feet (4.57 m),23 (link) speed was simply meters divided by time. Where available, data on fast gait speed (walk as fast as comfortably able25 (link)) and the Short Physical Performance Battery were obtained.26 (link) Survival for each individual used study monitoring methods, including the National Death Index and individual study follow-up. Time from gait speed baseline to death was calculated in days. Five-year survival status was confirmed for more than 99% of participants.
Additional variables include sex, age, race/ethnicity (white, black, Hispanic, other, defined by participant), height(centimeters), weight(kilograms), body mass index (BMI), calculated as weight in kilograms divided by height in meters squared (<25, 25–30, and >30), smoking (never, past, current), use of mobility aids (none, cane, walker), systolic blood pressure, self-reports of health (excellent or very good vs good, fair, or poor), hospitalization in the past year (yes/no), and physician-diagnosed medical conditions (cancer, arthritis, diabetes, and heart disease, all yes/no). Measures of self-reported functional status were not collected in all studies and varied in content and form. We created a dichotomous variable reflecting dependence in basic activities of daily living (ADLs) based on report of being unable or needing help from another person to perform any basic activity, including eating, toileting, hygiene, transfer, bathing, and dressing. For individuals independent in ADLs, we created a dichotomous variable reflecting difficulty in instrumental ADLs based on report of difficulty or dependence with shopping, meal preparation, or heavy housework due to a health or physical problem. Participants were then classified into 1 of 3 groups; dependent in ADLs, difficulty with instrumental ADLs, or independent. Physical activity data were collected in 6 studies, but time frames and items varied widely. Two studies used the Physical Activity Scale for the Elderly (PASE).27 (link) We dichotomized the PASEs core at 100.28 (link) We created operational definitions of other covariates that were reasonably consistent across studies. Covariates were identical for height, weight, BMI, and systolic blood pressure. Hospitalization within the prior year was determined largely by self-report, and chronic conditions were by self-report of physician diagnosis, with heart disease encompassing angina, coronary artery disease, heart attack, and heart failure.

Navigating NCBI Databases for Gene Expression Data
NCBI uses a search and retrieval system that can be used to search the content of its entire network of integrated databases including PubMed, GenBank, Genomes, Taxonomy, and many others [12 ] (see http://www.ncbi.nlm.nih.gov/gquery/gquery.fcgi). GEO data are available in two separate NCBI databases:

GEO DataSets: Users should use this database to search for studies of interest. The database stores all original submitter-supplied Platform, Sample and Series records, as well as curated gene expression DataSet records. Retrievals include the title, summary, organism, and accession for each record, as well as links to related data (Fig. 1). The GEO DataSets search interface is available at http://www.ncbi.nlm.nih.gov/gds/ or can be selected from the dropdown databases menu from the main search box on the NCBI home page at http://www.ncbi.nlm.nih.gov/.

GEO Profiles: Users should use this database to search for expression profiles of genes. The database stores gene expression profiles derived from curated DataSet records. Retrievals include the gene name, DataSet title, and a thumbnail image that depicts the expression values of that gene across each Sample in that DataSet. Experimental context is provided in the blocks at the foot of the charts making it possible to see immediately whether that gene is differentially expressed across experimental conditions (Fig. 2). Clicking on the thumbnail image enlarges the chart to reveal the full profile details, expression values, and the DataSet subsets that reflect experimental design, see Section 2.7 for more details). The GEO Profiles search interface is available at http://www.ncbi.nlm.nih.gov/geoprofiles/ or can be selected from the dropdown databases menu from the main search box on the NCBI home page at http://www.ncbi.nlm.nih.gov/.

Simple keyword searches work very well in these databases. For example, if a user wants to find studies that examine hepatocellular carcinoma, it is only necessary to type “hepatocellular carcinoma” into the GEO DataSets search box to retrieve all the DataSet, Series, and Sample records that mention that term. Similarly, if a user is studying the gene CREB5, it is only necessary to type “CREB5” into the GEO Profiles search box to retrieve all gene expression profile records for that gene across all DataSets.
Typical workflows within and between these databases depend on the aims of the user. Generally, if users want to identify particular studies of interest, they should search the GEO DataSets database first, and then they have the option to use either GEO2R (Section 2.8), GEO DataSets analysis tools (Section 2.6) or GEO Profiles analysis tools (Section 2.7) to identify specific genes or interesting gene expression patterns within those studies (Fig. 1 and Fig. 2). On the other hand, users want to see expression patterns of a favorite gene across any study, they can search the GEO Profiles database directly to see how that gene behaves across all DataSets.

Observational Study of Rheumatoid Arthritis Patients
One source of data employed was a large observational cohort of RA outpatients, who were seen on a regular basis, usually every 3 months. At each visit clinical, functional and laboratory core set variables [18 -20 (link)] and disease activity according to the composite scores DAS28 and SDAI were documented. Clinical assessments including joint counts were performed by independent, trained assessors who were not involved in treatment decisions. In July 2004, data on 998 patients followed in our clinics had been entered into the database. Each patient's first visit with complete documentation of clinical data was included to assemble the 'routine' cohort. There were 767 patients with at least one complete observation, and the first of these complete observations was used for the analyses. Of all 5070 patient observations that were initially documented, 2564 (50.6%) had missing data. Among these incomplete observations, 45% (n = 1150) had missing ESR and/or CRP values.
The second source of data was an independent cohort of newly diagnosed RA patients ('inception' cohort), whose visits were documented in the same manner as described above but starting from their first presentation to the clinic. The referral pattern and detailed follow up of these patients were described elsewhere [9 (link),27 (link)]. Radiographs of the hands and feet were obtained every 1–2 years, and were scored using the Larsen method [28 (link)] by a team of two experienced readers; they were presented to the readers in chronological order. Reassessment of a random subgroup of 40 radiographs of hands and feet revealed good agreement (R = 0.86, 95% confidence interval [CI] 0.81–0.91). All patients in the inception cohort received disease-modifying antirheumatic drugs, such as methotrexate, as soon as the diagnosis was made, with a few exceptions in patients who refused to take such therapy immediately.
The demographic and disease activity characteristics of patients in both cohorts are summarized in Table 1. Because several baseline variables were not normally distributed (see below), we present the median along with the first and third quartiles as robust descriptive measures.

Brain-Computer Interface for Robotic Arm Control
See Supplementary Information for additional Methods.
Permission for these studies was granted by the US Food and Drug Administration (Investigational Device Exemption; CAUTION: Investigational Device. Limited by Federal Law to Investigational Use Only) and the Partners Healthcare/Massachusetts General Hospital Institutional Review Board. Core elements of the investigational BrainGate system have been described previously6 (link),7 (link).
During each session, participants were seated in a wheelchair with their feet located near or underneath the edge of the table supporting the target placement system. The robotic arm was positioned to the participant’s right (Fig. 1a). Raw neural signals for each channel were sampled at 30 kHz and fed through custom Simulink (Mathworks Inc., Natick, MA) software in 100 ms bins (S3) or 20 ms bins (T2) to extract threshold crossing rates2 ,30 ; these threshold crossing rates were used as the neural features for real-time decoding and for filter calibration. Open and closed-loop filter calibration was performed over several blocks, which were each 3 to 6 minutes long and contained 18–24 trials. Targets were presented using a custom, automated target placement platform. On each trial, one of 7 servos placed its target (a 6 cm diameter foam ball supported by a spring-loaded wooden dowel rod attached to the servo) in the workspace by lifting it to its task-defined target location (Fig. 1b). Between trials, the previous trial’s target was returned to the table-top while next target was raised. Due to variability in the position of the target-placing platform from session to session and changes in the angles of the spring-loaded rods used to hold the targets, visual inspection was used for scoring successful grasp and successful touch trials. Further details on session setup, signal processing, filter calibration, robot systems, and target presentations are given in Methods.

LDACS-DME/TACAN Interference Mitigation
Not available on PMC !

Example 2

In this example also shown as Case 2 in FIG. 54, a transmission from LDACS-o 692a aircraft station may interfere with reception of the DME/TACAN aircraft 692b using that system. To prevent this interference, LDACS-o cell 406 should not be co-channeled in the air-to-ground direction with any DME/TACAN 402 ground-to-air signals within a two RHz40k distance. The RHz40k distance in an example indicates radio horizon for an aircraft at the highest cruising altitude of 40,000 feet. This distance may be estimated as:

R ⁢ H ⁢ z = RE × asin ⁡ ( [ ( R ⁢ E + h ⁢ A ) 2 - R ⁢ E 2 ] 1 / 2 R ⁢ E + h ⁢ A ) Where

    • RHz—radio horizon of a flying aircraft at altitude hA
    • RE—radius of the earth (6378.14 km)
    • hA—altitude of the aircraft
    • Substituting hA=40,000 feet (i.e., 12.2 km), one obtains:
      • RHz40k=394 km

High-Resolution Imaging of Hydraulic Fractures Using DAS
Not available on PMC !

Example 1

High-Resolution Imaging Using Microseismic Events on DAS Data.

Using the high-frequency data recorded in DAS array to form high-resolution seismic images, which are used to image hydraulic fractures. The embodiment of this example has several advantages or prior systems, including: (a) Sensors are closer to the sources thus can provide much higher frequency comparing to traditional surface seismic data; (b) microseismic data generally carries frequency around 200 Hz while the surface seismic data is usually below 30 Hz. High-frequency data will improve the spatial-resolution of seismic images; (c) microseismic data have much stronger S-wave amplitude comparing to the surface seismic data, which is dominated by P-wave. S-wave is sensitive to the highly compliant fluids. Thus, the seismic attributes derived from the S-wave seismic images can be used to identify the fluid-filled hydraulic fractures; (d) DAS array forms much larger aperture (generally much greater than 2000 feet) comparing to traditional geophones (usually less than 2000 feet), while having much smaller spatial interval between the sensors. Those properties are ideal for producing high-resolution seismic images.

A velocity model is built using known-sources, such as (perforation shots) and microseismic events. Next microseismic events using geophone or DAS arrays are located. From this a reflection traveltime table between sources/sensors to the image voxels is computed. Next events on the DAS data are identified, provided they are located by geophones. The DAS data is then migrated to form a seismic image. Computations are then performed on the seismic attributes for fracture identification.
