Article Title: Integrated beamline control and data acquisition for small-angle X-ray scattering at the P12 BioSAXS beamline at PETRAIII storage ring DESY

Figure Lengend Snippet: Schematic overview of the organization of the communication in BECQUEREL . The main interface has two major tasks: (i) controlling all devices at the beamline in a flexible manner and (ii) setting-up and triggering the data collection. All tasks, data collections and beamline optics are initiated through BECQUEREL , but an intermediary agent, the BMS, executes the commands during data collection. The communication is further mediated by an abstract communication layer, TINE, followed by the device specific servers that communicate directly to the hardware. BECQUEREL has different profiles for allowing smooth measurement and control of the different sample environments available at P12 ( a , robotic; b , SEC-SAXS; c , stop-flow; d , microfluidic spinning disk; e , in-air samples). Abstraction in the representation of the hardware makes it easy to establish communication following a switch between, for example, the four detectors or the two monochromators available. HFM and VFM refer to horizontal and vertical focusing mirror, respectively.

Figure Lengend Snippet: Screen-shot of the BECQUEREL GUI. ( a ) Left-most widgets give an overview of monitor readings specific to the profile, and a view of the sample holder (here, robotic sample-changer mode with a capillary view). The central widget accepts sample specifications of the user and displays the well structure of the sample holder. The upper right corner widget contains the status of the BMS and the current command queue. The queue can be paused, cleared and aborted (row of buttons). The Recommender widget (lower right corner) suggests commands and appropriate actions to take to allow for a data collection. Convenient shortcuts in the form of buttons are available in the top row, for submitting measurements and normalization measurements, breaking interlocks and accessing the data-collection directory. ( b ) Plot-tab, here showing transmitted beam over time during a robotic sample changer data collection. ( c ) Hardware tree-tab, with the hardware widget of a guard slit motor shown.

( a ) Results of a slit scan with GGCDF and GGPDF fits to the experimental data and numerical derivatives. Re-scans can be made, and data appended to supplement the scan range. ( b ) Result of a fully automated positioning of a slit system. Data represented as beam profiles described by GGPDF are plotted in MATLAB. ( c ) Data from an adaptive scan (three steps) of one slit blade.

Article Title: Telemetric electroencephalography recording in anesthetized mice—A novel system using minimally-invasive needle electrodes with a wireless OpenBCI™ Cyton Biosensing Board

doi: 10.1016/j.mex.2023.102187

Figure Lengend Snippet: Telemetric EEG recording using needle electrodes and OpenBCI™. Mice under isoflurane anesthesia were situated for EEG recording via subdermal needle electrodes integrated with the OpenBCI™ 8-channel Cyton Biosensing Board. The device contains various hardware features such as a Texas Instruments© ADS1299 Analog-to-Digital Converter (Texas Instruments, TX, USA). The processed raw EEG data is wirelessly transmitted through RFduino™ Low Power Bluetooth™ radio transmission signals and received at the USB dongle host on a computer node. The EEG signals are then stored and visualized at the computer node via the data acquisition, processing, and design tool OpenBCI™ graphical user interface .

Article Snippet: For visual interpretation and control of signal acquisition, live raw EEG signals can be seen on the computer [where data is received] through the data acquisition, processing, and design tool OpenBCI™ graphical user interface (GUI).
