Lacuna (manuscripts)
A lacuna ( lacunae or lacunas) is a gap in a manuscript, inscription, text, painting, or musical work. A manuscript, text, or section suffering from gaps is said to be "lacunose" or "lacunulose". Weathering, decay, and other damage to old manuscripts or inscriptions are often responsible for lacunae - words, sentences, or whole passages that are missing or illegible. Palimpsests are particularly vulnerable. To reconstruct the original text, the context must be considered. In papyrology and textual criticism, this may lead to competing reconstructions and interpretations. Published texts that contain lacunae often mark the section where text is missing with a bracketed ellipsis. For example, "This sentence contains 20 words, and ..nouns," or, "Finally, the army arrived at ..and made camp." Notable examples See also * Unfinished work Unfinished may refer to: *Unfinished creative work, a work which a creator either chose not to finish or was prevented from finishing. ...

Lacunary Polynomial
In mathematics, a sparse polynomial (also lacunary polynomial or fewnomial) is a polynomial that has far fewer terms than its degree and number of variables would suggest. Examples include *monomials, polynomials with only one term, * binomials, polynomials with only two terms, and *trinomials, polynomials with only three terms. Research on sparse polynomials has included work on algorithms whose running time grows as a function of the number of terms rather than on the degree, for problems including polynomial multiplication, root-finding algorithms, and polynomial greatest common divisors. Sparse polynomials have also been used in pure mathematics, especially in the study of Galois groups, because it has been easier to determine the Galois groups of certain families of sparse polynomials than it is for other polynomials. The algebraic varieties determined by sparse polynomials have a simple structure, which is also reflected in the structure of the solutions of certain related diff ...

Lacunarity
Lacunarity, from the Latin lacuna, meaning "gap" or "lake", is a specialized term in geometry referring to a measure of how patterns, especially fractals, fill space, where patterns having more or larger gaps generally have higher lacunarity. Beyond being an intuitive measure of gappiness, lacunarity can quantify additional features of patterns such as "rotational invariance" and more generally, heterogeneity. This is illustrated in Figure 1 showing three fractal patterns. When rotated 90°, the first two fairly homogeneous patterns do not appear to change, but the third more heterogeneous figure does change and has correspondingly higher lacunarity. The earliest reference to the term in geometry is usually attributed to Benoit Mandelbrot, who, in 1983 or perhaps as early as 1977, introduced it as, in essence, an adjunct to fractal analysis. Lacunarity analysis is now used to characterize patterns in a wide variety of fields and has application in multifractal analysis in particu ...

Lacunary Function
In analysis, a lacunary function, also known as a lacunary series, is an analytic function that cannot be analytically continued anywhere outside the radius of convergence within which it is defined by a power series. The word ''lacunary'' is derived from lacuna (''pl.'' lacunae), meaning gap, or vacancy. The first known examples of lacunary functions involved Taylor series with large gaps, or lacunae, between the non-zero coefficients of their expansions. More recent investigations have also focused attention on Fourier series with similar gaps between non-zero coefficients. There is a slight ambiguity in the modern usage of the term lacunary series, which may refer to either Taylor series or Fourier series. A simple example Let a\in\mathbb\cap\left ''z'', 0 is an arbitrary positive constant, then ''f''(''z'') is a lacunary function that cannot be continued outside its circle of convergence. In other words, the sequence doesn't have to grow as fast as 2''k'' for ''f''(''z'') ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lacuna Coil
Lacuna Coil is an Italian gothic metal band from Milan. Since their formation in 1994, the group has had two name changes, being previously known as Sleep of Right and Ethereal, and they have recorded nine studio albums, two extended plays, two live albums, two compilation albums, one video album, and sixteen singles and music videos. Inspired by the combination of Gothic aesthetics, gothic imagery and music, the members have been known, musically, for composing mid-tempo songs consisting of prominent guitar lines and contrasting dual female/male vocal harmonies to help create a melodic, detached sound. Much of the band's recent material, however, sees a heavier and more down-tuned style, featuring a more distinct bass line and a higher mixing of the guitars within the songs. They have toured internationally and were nominated in 2006 for a MTV Europe Music Award for Best Italian Act, MTV Europe Music Award. They won the 2012 Metal Female Voices Fest Award for the Best Album, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lacunar Stroke
Lacunar stroke or lacunar cerebral infarct (LACI) is the most common type of ischemic stroke, resulting from the occlusion of small penetrating arteries that provide blood to the brain's deep structures. Patients who present with symptoms of a lacunar stroke, but who have not yet had diagnostic imaging performed, may be described as having lacunar stroke syndrome (LACS). Much of the current knowledge of lacunar strokes comes from C. Miller Fisher's cadaver dissections of post-mortem stroke patients. He observed "lacunae" (empty spaces) in the deep brain structures after occlusion of 200–800 μm penetrating arteries and connected them with five classic syndromes. These syndromes are still noted today, though lacunar infarcts are diagnosed based on clinical judgment and radiologic imaging. Signs and symptoms Each of the five classical lacunar syndromes has a relatively distinct symptom complex. Symptoms may occur suddenly, progressively, or in a fluctuating (e.g., the cap ...

Lacunar Amnesia
Lacunar amnesia is the loss of memory about a specific event. This specific form of amnesia is caused by brain damage in the limbic system which is responsible for our memories and emotions. When the damage occurs it leaves a lacuna, or a gap, in the record of memory within the cortex region of the brain. There is a general belief that certain emotions from the lost memory may be triggered without the recollection of the event. Characteristics Daniel Goleman, in his book ''Vital Lies, Simple Truths'', defines a lacuna as: "...the sort of mental apparatus that diversionary schemas represent. A lacuna is, then, the attentional mechanism that creates a defensive gap in awareness. Lacunas, in short, create blind spots." Lacunar amnesia has also been known to be attributed to alcoholism, drug treatment, and withdrawal in some cases. After using these substances a person may experience a loss of memory of a specific event temporarily or even permanently. Steven Johnson, (the author ...

Lacuna Model
The lacuna model is a tool for unlocking culture differences or missing "gaps" in text (in the further meaning). The lacuna model was established as a theory by Jurij Sorokin and Irina Markovina (Russia), further developed by Astrid Ertelt-Vieth and Hartmut Schröder (Germany) and practical research tested in ethnopsycholinguistics (Igor Panasiuk 2000 and 2005), Russian studies (Vladimir Zhelvis 2002; Astrid Ertelt-Vieth 1987; 2005), American studies (Iosif Sternin and Marina Sternina 2001), Arabic studies (Sherine Elsayed 2005), Germanics studies (Elena Denisova-Schmidt 2005), Finnish studies (Pirkko Muikku-Werner 2005), literature studies (Irina Markovina 2005), foreign language acquisition (Natalia Turunen 2005), film studies (Hannah Sard 2005), journalism (B.

Lakes Of Titan
Lakes of ethane and methane on Titan, Saturn's largest moon, have been detected by the ''Cassini–Huygens'' space probe, and had been suspected long before. The large ones are known as maria (seas) and the small ones as lacūs (lakes). History The possibility that there were seas on Titan was first suggested based on data from the Voyager 1 and 2 space probes, launched in August and September 1977. The data showed Titan to have a thick atmosphere of approximately the correct temperature and composition to support them. Direct evidence was not obtained until 1995 when data from the Hubble Space Telescope and other observations had already suggested the existence of liquid methane on Titan, either in disconnected pockets or on the scale of satellite-wide oceans, similar to water on Earth. The ''Cassini'' mission affirmed the former hypothesis, although not immediately. When the probe arrived in the Saturnian system in 2004, it was hoped that hydrocarbon lakes or oceans might ...
