Garfunkel - Trager family papers undated, 1892-1905, 1911-1941, 1954, 1966-1998
Contains research and original documents compiled by Milton M. Gottesman for his book "Hoopskirts and Huppas: A Chronicle of the Early Years of the Garfunkel-Trager Family in America, 1836-1920." Original documents are numbered to correspond with the book's chapter notes. Original documents primarily consist of correspondence between Garfunkel and Trager family members. Letters written by Louis Trager and Mark Moses are also available; as well letters between Aaron Garfunkel and his grandfather Abraham Isaac. Aaron Garfunkel pocket diaries from 1892-1940 form the second half of the collection. Research documents on Louis Trager's Civil War career include official records of the Union and Confederate Army, copies of correspondence concerning his appointment as U.S. Consul, and a copy of a recommendation letter from U.S. Grant Major General to Major General H.W. Halleck. Further research pertains to copies of Garfunkel family birth registers from Rzeskow, marriage and anniversy notices (Moses and Mashe Hennie Garfunkel; Aaron and Sarah Garfunkel; Ray and Nathan Adler), obituary clippings and articles (Abraham Isaac Trager, Moses Garfunkel, B.M. Garfunkel, Max Lubetkin, Aaron Garfunkel, and extended Garfunkel members), death certificates (Max and Rachel Lubetkin), copies of Moses Garfunkel's 1870 census records, a copy of a deed of slave to Abraham Isaac Trager, and a memoir written by Esther Garfunkel Gottesman. The Garfunkel-Trager hoopskirt business is documented through newsclipping of advertisements, a partnership contract for a new hoopskirt business in New York City, and advertisements and catalogs for the Broadway Bargain House. Information is also available regarding the founding of Beth Hamedrash Hagadol (New York, NY), Eldgridge Street Synagogue (New York, NY), and Congregation Tree of Life (Columbia, SC) as well as Montefiore Hospital (New York, NY)Milton M.

Worker description. This species is most similar to longicornis, but is shinier and has less pilosity. Head rectangular to weakly hexagonal, HL greater than HW; with conspicuous vertex pilosity consisting of (5) 8–20 erect macrosetae; scapes at least reaching, normally surpassing vertex corners, gradually thickening in distal half; pronotum with 0–6 dorsal erect setae; mesonotal profile weakly convex for most of its length; propodeal profile variable ranging from evenly rounded to a weakly obtuse, rounded angle; petiole narrow, sides convex and converging dorsad, petiolar dorsum rounded or with median portion flat, less often feebly concave; first tergite lacking pubescence; first tergite pilosity sparse, weakly flexuous or straight. Head matte to very faintly shining; mesosoma matte dorsally but shining laterally; gaster weakly shining to shiny. Discussion. This is among the three largest species of the lucidus group, almost in the same size range as longicornis, but characterized by a shinier head and mesosoma, especially the pronotum, and less abundant pilosity, especially on the vertex. Color is clear red with at most slight infuscation of the extremities. P. r u b e r appears intermediate between longicornis and lucidus in its proportions, pilosity, and shininess. The sheen and lesser vertex pilosity distinguishes ruber from the more matte longicornis (ruber ½ VeM 13) while the longer appendages distinguish it from lucidus (ruber SI> 92 + vs. lucidus <91). Etymology. With the name ruber, Latin for red or ruddy, I refer to the brighter, all-red color of this ant species, in comparison to other southeastern species, especially the somewhat similar, but dark-legged longicornis. Natural history. Polyergus ruber tracks its host, F. biophilica, in distribution, namely, a U-shaped range south from Maryland to Georgia, west to Louisiana, then north to eastern Missouri. It would be unsurprising if this ant showed up from collecting in at least southern Illinois. Polyergus ruber was studied by Vargo and Gibbs (1987, reported as lucidus longicornis) in Athens, GA. Aside from its unique host association, ruber seems much like its relatives in the lucidus group in most respects. Raids were observed from early June to mid-August, and may have continued after these observations ended, as the activity was still vigorous, so perhaps starting just a few weeks earlier and persisting perhaps a bit longer than in other species of the group. I observed parts of a raid, and a mating flight that occurred several hours before the raid, in Georgia, and two raids of these ants in Missouri, all in July, and they are much like those of the other species. At both locations, pre-raiding milling was initiated around 1700 hr. The size of raiding parties in the Georgia colonies was estimated between 500 and 1000, quite large compared to other known lucidus group species. Colonies and raiding parties were somewhat smaller in Missouri. Vargo and Gibbs observed dealate gynes near the outskirts of nests before raids in late July, and saw one of these follow a raid and enter the raided nest. Habitats of this species included a variety of upland, grassy and open woodland types, with acid soils. Distribution of studied specimens. GEORGIA Clarke Co. Athens. 165 Doe Run. Flight at noon.

High-resolution clean-sc
In this paper a high-resolution extension of CLEAN-SC is proposed: HR-CLEAN-SC. Where CLEAN-SC uses peak sources in “dirty maps” to define so-called source components, HR-CLEAN-SC takes advantage of the fact that source components can likewise be derived from points at some distance from the peak, as long as these “source markers” are on the main lobe of the Point Spread Function (PSF). This is very useful when sources are closely spaced together, such that their PSFs interfere. Then, alternative markers can be sought in which the relative influence by PSFs of other source positions is minimised. For those markers the source components better agree with the actual sources, which allows for better estimation of their locations and strengths. This paper outlines the theory needed to understand this approach and discusses applications to 2D and 3D microphone array simulations with closely spaced sources

Ca-modified Al–Mg–Sc alloy with high strength at elevated temperatures due to a hierarchical microstructure
Al-Mg alloys are normally prone to lose part of their yield and tensile strength at high temperatures due to insufficient thermal stability of the microstructure. Here, we present a Ca-modified Al–Mg–Sc alloy demonstrating high strength at elevated temperatures. The microstructure contains Al4Ca phases distributed as a network along the grain boundary and Al3(Sc,Zr) nano-particles dispersed within the grains. The microstructure evolution and age-hardening analysis indicate that the combination of an Al4Ca network and Sc-rich nano-particles leads to excellent thermal stability even upon aging at 300 °C. The tensile strength of the alloy for temperatures up to 250 °C is significantly improved by an aging treatment and is comparable with the commercial heat-resistant aluminum alloys, i.e., A356 and A319. At a high temperature of 300 °C, the tensile strength is superior to the above-mentioned commercial alloys, even more so when expressed as the specific strength due to the low density of Ca-modified Al–Mg–Sc alloy. The excellent high-temperature strength results from a synergistic effect of solid solution strengthening, grain boundary strengthening and nanoparticle order strengthening.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Novel Aerospace Material
