  • LET'S BE CLEAR

    When writing, clarity is essential. If writing is unclear, the reader may become confused or frustrated, which may lead them to stop reading altogether. Using ambiguous words, or words that have more than one meaning, without clarification can make writing unclear. Pronouns like “their” or “it” are commonly ambiguous, as the following illustrates: “The project managers report potential risks and suggest approaches according to their guidelines.” What does “their” refer to? The project managers’ guidelines? The guidelines of the approaches? A simple rewording can clarify: “…managers report potential risks and, according to their guidelines, suggest approaches….” 

    Disconnected or oddly arranged wording also may cause a lack of clarity. In the following example, watch for the confusion over what took place and where: “The athlete said she and her team mutually agreed to part ways in an online video.” Does the video show the team agreeing to part ways or just the athlete announcing it happened? If the latter, then moving the “video posted” phrase would clarify: “In an online video, the athlete said….” 

    Looking carefully for ambiguities and removing them can sharpen your writing — and sharp writing keeps readers reading. For questions, contact Dave Bounds at x2859 (virtual office hours: Tuesday and Thursday, 9-11 a.m.). Happy writing!

  • WATCH YOUR TONE!

    All writing has a voice, which is often referred to as “tone.” Word choice and order, sentence and paragraph length and even punctuation are all factors that contribute to someone’s tone.

    A tone may be authoritative, conversational, scientific, diplomatic and so on. In these examples, note how all are saying essentially the same thing in varying tones:

    • The following documentation presents a full explanation of the incident as requested.
    • You’ll find everything that happened below.
    • To understand the incident, read on. All details are accounted for.

    There are several ways to write the same sentence and just as many ways to convey tone. Which of the above sounds like a professional statement? An informal comment? The answers reveal themselves in the details.

    When put together, words like “documentation” and “explanation” give an official tone. Personalized wording like “you’ll find” "read on” convey a confident, possibly casual tone. Wording matters! How does your wording make up your tone? What wording could you change to better suit your intended tone?

  • MAKE WRITING FLOW WITH “PARAGRAPHING”

    Just as the sentences in a good paragraph connect to create a train of thought, paragraphs themselves should flow together to create the train of thought for whatever it is you are writing. From introduction to body to conclusion, paragraphs are key. “Paragraphing” well is all about moving your reader’s attention smoothly from one paragraph to the next.

    Incorporating smooth transitions, or segues, between your paragraphs comes down to two methods. The first method is using key words in the start of the paragraph (or toward the beginning) that shape the reader’s expectations for what comes next. For example: Instead of “Several proposals came through...,” try starting your paragraph with “In the first proposal...” Delegating your discussion items into their own paragraphs not only directs your reader’s attention but organizes your own thoughts.

    The paragraph above did this by mentioning two transition methods but only discussing one. The second method is to feature key words in the concluding line of a paragraph to set up what comes next. A paragraph on IT updates might mention “...which brings up implications for cybersecurity,” in the concluding sentence. The next paragraph can then jump right into discussing those implications.

  • SENTENCES MATTER!

    Writing usually involves a lot of shaping and rearranging sentences. If one sentence is too long, awkwardly worded, or just “off,” it can distract readers. Assessing the way sentences are structured is essential to improving your writing skills.

    No matter the sentence, it always come down to the subject and the verb. For example: “She wrote.” Anything outside of this sentence just concerns the details. To expand on the example: “She wrote an assessment of the initial efforts of the new program, which began in FY 2021.” In that sentence, the subject remains “she” and the action remains “wrote.” The rest pertains to what she wrote about. To make this flow better, we could break the sentence in two: “She wrote an assessment of the program. The initial efforts began in FY 2021.”

    Which is easier to read? The longer sentence or the two shorter sentences? How would you restructure sentences in your own writing to allow for better flow and focus?

    Maintaining a subject/verb can ease the stress that comes with finding places to put the extra details. The subject/verb focus is key to creating compelling sentences.

  • Thomas Jefferson National Accelerator Facility (Jefferson Lab) provides scientists worldwide the lab’s unique particle accelerator, known as the Continuous Electron Beam Accelerator Facility (CEBAF), to probe the most basic building blocks of matter by conducting research at the frontiers of nuclear physics (NP) and related disciplines. In addition, the lab capitalizes on its unique technologies and expertise to perform advanced computing and applied research with industry and university partners, and provides programs designed to help educate the next generation in science and technology.

    Majority of computational science activities in Jefferson Lab focus on these areas : large scale and numerical intensive Lattice Quantum Chromodynamics (LQCD) calculations, modeling and simulation of accelerators and the experiment detectors, fast data acquisition and streaming data readout, high throughput computing for data analysis of experimental data, and large scale distributed data storage and management.

    Many Jefferson Lab scientists and staffs lead or actively participate the computational efforts in the above areas. Among those are computer/computational scientists and computer professionals from newly formed computational sciences and technology division (CST), physicists from physics division and the Center for Theoretical and Computational Physics, and accelerator physicists from Center for Advanced Studies of Accelerators (CASA). In addition, collaborations with universities and industrial partners further research and development in computational science.

    Jefferson Lab maintains various state of art high performance computing resources onsite. CSGF students will utilize these resources to carried out their researches in the specific areas described below:

    Accelerator Modeling

    CASA and Jefferson Lab SRF institute focus on advanced algorithms, such as fast multipole methods, for multiparticle accelerator dynamics simulations, artificial intelligence (AI) and machine learning (ML) applied to superconducting RF (SRF) accelerator operations, and integrated large and multi-scale modeling of SRF accelerator structures. These areas will be an essential part of a national strategy to optimize DOE operational facility investments, and to strengthen Jefferson Lab’s core competency of world-leading SRF advanced design and facility operations. Especially, current active simulation projects

    like electron cooling, intra-beam scattering, and coherent synchrotron radiation present diverse research domains ranging from numerical algorithms development to parallel computing.

    Streaming Data Readout

    With tremendous advancement in micro-electronics and computing technologies in the last decade, many nuclear physics and high-energy physics experiments are taking advantage of these developments by upgrading their existing triggered data acquisition to a streaming readout model (SRO) , whereby detectors are continuously read out in parallel streams of data. An SRO system, which could handle up to 100 Gb/s data throughput, provides a pipelined data analysis model to nuclear physics experiments where data are analyzed and processed in near real-time fashion. Jefferson Lab is leading a collaborative research and development effort to devise SRO systems not only for CEBAF 12GeV experiments but also for the upcoming EIC facility. SRO development offers CSGF students some exciting research areas such as network protocol design, high speed data communication, high performance data compression and distributed computing.

    Physics Data Analysis

    Analysis of data from modern particle physics experiments uses technically advanced programming and computing techniques to handle the large volumes of data. One not only needs to understand aspects of parallel programming using modern languages such as C/C++, Java, and Python, but also must incorporate knowledge of experimental techniques involving error propagation and estimation in order to properly interpret the results. Aspects of this range from writing a single algorithm used in event reconstruction, to using the collection of algorithms written by others, to managing campaigns at HPC facilities that apply these algorithms to large datasets. Detector calibrations and final physics analysis are also significant parts of the analysis chain. CSGF students could participate in any of these areas.

    Machine Learning

    Rapid developments in hardware computational power and an ever increasing set of data has lead to explosive growth in machine learning techniques, specifically deep learning techniques. These techniques threaten to change just about every facet of modern life and nuclear physics is no exception. At Jefferson Lab machine learning is being developed for every step in the physics workflow. To deliver beam to the experimental halls the accelerator relies on radio frequency (RF) cavities to accelerate the electrons. Occasionally these cavities, of which there are over 400 in operation around the accelerator, fault which disrupts the delivery of the beam to experiments. To quickly identify and diagnose cavity faults A.I. is being developed and deployed. Experiments themselves are developing and/or deploying A.I. to monitor detector performance, decide what data to keep, reconstruct detector responses, simulate the detectors, and even to analyze collected data. With the active development of machine learning tools and techniques Jefferson Lab hopes to drive nuclear physics research forward, enabling physicists to more quickly obtain and analyze high quality data.
