LOD (countable and uncountable, plural LODs)

  1. (chemistry, initialism) Limit of detection; the smallest concentration that can be detected using a specific method.
    • 2005, Jack Cazes, Encyclopedia of Chromatography - Volume 2, →ISBN, page 1450:
      The lowest response region in the spectrum is that which has the LOD as the upper bound. It is clear that if a response that is smaller than the response associated with the LOD is observed, the analytical result should be reported as "less than the LOD" or "not detected."
    • 2011, Thomas P. Knepper & Frank T. Lange, Polyfluorinated Chemicals and Transformation Products, →ISBN, page 145:
      PFOS exceeded the LOD in potatoes, canned vegetables, eggs, sugars, and preserves, with highest levels detected in potatoes (10 ng/g ww).
    • 2016, Piotr Konieczka & Jacek Namiesnik, Quality Assurance and Quality Control in the Analytical Chemical Laboratory, →ISBN, page 145:
      When calculating the LOD, one uses the determined S/N ratio for the investigated analytical procedure [2].
  2. (initialism) Alternative form of lod
    • 1998, Thomas D. Gelehrter, Francis S. Collins, & David Ginsburg, Principles of Medical Genetics, →ISBN, page 200:
      In practice, the LOD score is computed over a wide range of values for 6.
    • 2010, Andreas Ziegler & Inke R. König, A Statistical Approach to Genetic Epidemiology, →ISBN, page 158:
      For historical reasons, the LOD score functions LOD(Θ) = log ʌ(Θ) is preferred in genetic epidemiologial applications over LR(Θ) = 2ln ʌ(Θ).
    • 2005, Linda A. Ferrera, Body Mass Index: New Research, →ISBN, page 150:
      One would expect that LOD (logarithm of odds) scores based on small sample sizes would be unstable and contribute to lack of replication.
  3. (computer graphics, initialism) Level of detail.
    • 2004, Antony Ward, Game Character Development with Maya, →ISBN, page 687:
      We have worked hard to tweak the weights on the first LOD until Kila deforms accurately as she moves.
    • 2006, Hongbin Zha, Interactive Technologies and Sociotechnical Systems, →ISBN:
      The paper proposes a time-controlling algorithm for large-scale terrain rendering, which can't be efficiently dealt with by LOD technique.
    • 2007, Cyril Brom, Ondřej Šerỹ, & Tomáš Poch, “Simulation Level of Detail for Virtual Humans”, in Intelligent Virtual Agents:
      Graphical level of detail (LOD) is a set of techniques for coping with the issue of limited computational resources by reducing the graphical detail of the scene far from the observer. Simulation LOD reduces quality of the simulation at the places unseen. Contrary to graphical LOD, simulation LOD has been almost unstudied.
  4. (initialism) Length of day.
    • 1982, S. Ponsar, V. Dehant, R. Holme, D. Jault, A. Pais, & T. Van Hoolst, The Core and Fluctuations in the Earth's Rotation:
      On very long time scale, tidal friction is responsible for a secular decrease in the Earth's rotation rate and thus for an increase in the length of day (LOD) (for more details, see for instance Brosche and Sṻndermann [1978]).
    • 1998, Ronald T. Merrill, M. W. McElhinny, & Phillip L. McFadden, The Magnetic Field of the Earth, →ISBN:
      This long-term change in the LOD must be reomoved from the total change to obtain the short period and decade variations.
    • 2002, Claudio Vita-Finzi, Monitoring the Earth: Physical Geology in Action, →ISBN, page 51:
      Artificial satellites now provide a direct measure of changes in LOD (Fig. 4. lb), and laser ranging to the Moon underpins calculations of changes in the mean angular velocity of the Moon.
  5. (military, law, initialism) Line of duty; an official determination of whether something occurred in the line of duty.
    • 1996, Richard A. Gittins & Kirk L. Davies, The Military Commander and the Law, →ISBN, page 222:
      Additionally, commanders should note that a LOD proceeding is neither a substitute for, nor a bar to, such disciplinary action as may be warrented.
    • 2009, E. Kelly Taylor, America's Army and the Language of Grunts, →ISBN:
      LOD investigations are usually a result of a soldier or other personnel being killed or injured, and the investigation is necessary to determine if the cause was in the line of duty, or if the actions that caused the casualties or injuries were a result of neglect or misconduct and not in the line of duty.
    • 2015, Janelle B. Moore, Cheryl Lawhorne-Scott, & Don Philpott, The Wounded Warrior Handbook, →ISBN:
      An unfavorable LOD determination disqualifies a service member from receiving disability compensation.
  6. (computing, initialism) Linked Open Data; An international project that links data in the Web.
    • 2013, Erik T. Mitchell, Library Linked Data: Research and Adoption, →ISBN, page 15:
      While most LOD metadata employs multiple vocabularies and metadata schemas for description, for the sake of simplicity this exploration of RDF will use only a single metadata schema, Dublin Core.
    • 2013, Hideaki Takeda, Yuzhong Qu, & Riichiro Mizoguchi, Semantic Technology, →ISBN:
      LOD (Linked Open Data) is an international endeavor to interlink structured data on the Web and create the Web of Data on a global level. In this paper, we report about our experience of applying existing LOD frameworks, most of which are designed to run only in European language environments, to Korean resources to build linked data.
    • 2014, Janusz Sobecki, Veera Boonjing, & Suphamit Chittayasothorn, Advanced Approaches to Intelligent Information and Database Systems, →ISBN:
      The LOD Cloud is a collection of the available datasets of the Semantic Web.
  7. (initialism) Line of dance; A counterclockwise direction for circuiting the dance floor.
    • 1962, Sets in Order: The Magazine of Square Dancing - Volume 14, page 37:
      Position: Intro, Left-Open, M on outside, M's L and W's R hands joined, both facing LOD.
    • 2012, Raoul Weinstein, Become a Man of Confi-Dance, →ISBN:
      Beginners will often use a box step or not get too involved in the LOD until they get a feel of matching their steps with the musical measures.
    • 2013, Judy Patterson Wright, Social Dance: Steps to Success, →ISBN, page 297:
      If the dance floor is very crowded and you cannot travel forward in a counterclockwise direction around the perimeter of the room, or in the LOD, the leader needs to select from the stationary variations that are known so far.
