    Integral digitalization aims to liaise with Universal interface for human-computer interaction, assemble Brewing aggregation via online analytical processing, and engage Centered user experience (UBC), which enables wiseCIO to orchestrate “Anything-as-a-Service” (XaaS). This paper presents three important concepts such as iDATA, iDEA and ACTiVE that together orchestrate XaaS on wiseCIO. iDATA stands for “integral digitalization via archival transformation and analytics” in support of content management, iDEA denotes “intelligence-driven efficient automation” for UBC processing with little coding required via machine learning automata, and ACTiVE represents “accessible, contextual and traceable information for vast engagement” with content delivery. Where iDATA is central to XaaS through computational thinking applied to multidimensional online analytical processing (mOLAP). Case studies are through discussed on the massive basis through iDATA over broad fields, such as manageable ARM (archival repository for manageable accessibility), animated BUS (biological understanding from STEM), sensible DASH (deliveries assembled for fast search & hits), smart DIGIA (digital intelligence governing instruction and administering), informative HARP (historical archives & religious preachings), vivid MATH (mathematical apps in teaching and hands-on exercise), and engaging SHARE (studies via hands-on assignment, review/revision and evaluation). As a result, iDATA-orchestrated wiseCIO is in favor of archival content management (ACM) and massive content delivery (MCD).more »Most recently, the comprehensive online teaching and learning (COTL) has been prepared and published as ACTiVE courseware with various multimedia and the student online profiles for paperless homework, labs and submissions. The ACTiVE courseware is integrated with a capacity equivalent to 10,000 + traditional web pages and broadly used for advanced remote learning (ARL) in both synchronous model and asynchronous model with great ease.« less
  3. Abstract. As cloud-based web services get more and more capable, available, and powerful (CAP), data science and engineering is pulled toward the frontline because DATA means almost anything-as-a-service (XaaS) via Digital Archiving and Transformed Analytics. In general, a web service (via a website) serves customers with web documents in HTML, JSON, XML, and multimedia via interactive (request) and responsive (reply) ways for specific domain problem solving over the Internet. In particular, a web service is deeply involved with UI & UX (user interface and user experience) plus considerate regulations on QoS (Quality of Service) as well, which refers to both information synthesis and security, namely availability and reliability for providential web services. This paper, based on the novel wiseCIO as a Platform-as-a-Service (PaaS), presents digital archiving 3 and transformed analytics (DATA) via machine learning, one of the most practical aspects of artificial intelligence. Machine learning is the science of data analysis that automates analytical model building and online analytical processing (OLAP) that enables computers to act without being explicitly programmed through CTMP. Computational thinking combined with manageable processing is 4 thoroughly discussed and utilized for FAST solutions in a feasible, analytical, scalable and testable approach. DATA is central to informationmore »synthesis and analytics (ISA), and digitized archives plays a key role in transformed analytics on intelligence for business, education and entertainment (iBEE). Case studies as applicable examples are discussed over broad fields where archival digitization is required for analytical transformation via machine learning, such as scalable ARM (archival repository for manageable accessibility), visual BUS (biological understanding from STEM), schooling DIGIA (digital intelligence governing instruction and administering), viewable HARP (historical archives & religious preachings), vivid MATH (mathematical apps in teaching and hands-on exercise), and SHARE (studies via hands-on assignment, revision and evaluation). As a result, wiseCIO promotes DATA service by providing ubiquitous web services of analytical processing via universal interface and user-centric experience in favor of logical organization of web content and relational information groupings that are vital steps in the ability of an archivist or librarian to recommend and retrieve information for a researcher. More important, wiseCIO also plays a key role as a content management system and delivery platform with capacity of hosting 10,000+ traditional web pages with great ease.« less
  4. Abstract Understanding propagation of scintillation light is critical for maximizing the discovery potential of next-generation liquid xenon detectors that use dual-phase time projection chamber technology. This work describes a detailed optical simulation of the DARWIN detector implemented using Chroma, a GPU-based photon tracking framework. To evaluate the framework and to explore ways of maximizing efficiency and minimizing the time of light collection, we simulate several variations of the conventional detector design. Results of these selected studies are presented. More generally, we conclude that the approach used in this work allows one to investigate alternative designs faster and in more detail than using conventional Geant4 optical simulations, making it an attractive tool to guide the development of the ultimate liquid xenon observatory.

  5. Abstract The selection of low-radioactive construction materials is of the utmost importance for rare-event searches and thus critical to the XENONnT experiment. Results of an extensive radioassay program are reported, in which material samples have been screened with gamma-ray spectroscopy, mass spectrometry, and $$^{222}$$ 222 Rn emanation measurements. Furthermore, the cleanliness procedures applied to remove or mitigate surface contamination of detector materials are described. Screening results, used as inputs for a XENONnT Monte Carlo simulation, predict a reduction of materials background ( $$\sim $$ ∼ 17%) with respect to its predecessor XENON1T. Through radon emanation measurements, the expected $$^{222}$$ 222 Rn activity concentration in XENONnT is determined to be 4.2 ( $$^{+0.5}_{-0.7}$$ - 0.7 + 0.5 )  $$\upmu $$ μ Bq/kg, a factor three lower with respect to XENON1T. This radon concentration will be further suppressed by means of the novel radon distillation system.

  7. Precisely forecasting wind speed is essential for wind power producers and grid operators. However, this task is challenging due to the stochasticity of wind speed. To accurately predict short-term wind speed under uncertainties, this paper proposed a multi-variable stacked LSTMs model (MSLSTM). The proposed method utilizes multiple historical meteorological variables, such as wind speed, temperature, humidity, pressure, dew point, and solar radiation to accurately predict wind speeds. The prediction performance is extensively assessed using real data collected in West Texas, USA. The experimental results show that the proposed MSLSTM can preferably capture and learn uncertainties while output competitive performance.
  8. Abstract A novel online distillation technique was developed for the XENON1T dark matter experiment to reduce intrinsic background components more volatile than xenon, such as krypton or argon, while the detector was operating. The method is based on a continuous purification of the gaseous volume of the detector system using the XENON1T cryogenic distillation column. A krypton-in-xenon concentration of (360±60)ppq was achieved. It is the lowest concentration measured in the fiducial volume of an operating dark matter detector to date. A model was developed and fit to the data to describe the krypton evolution in the liquid and gas volumes of the detector system for several operation modes over the time span of 550 days, including the commissioning and science runs of XENON1T. The online distillation was also successfully applied to remove 37Ar after its injection for a low energy calibration in XENON1T. This makes the usage of 37Ar as a regular calibration source possible in the future. The online distillation can be applied to next-generation LXe TPC experiments to remove krypton prior to, or during, any science run. The model developed here allows further optimization of the distillation strategy for future large scale detectors.
