Design rainfalls under climate change scenarios in South East Queensland, Australia: A Brisbane River case study
This study updates design rainfalls for the Brisbane River Basin, Australia, employing rainfall data from eight CMIP5 General Circulation Models (GCMs) across two Representative Concentration Pathways (RCP 4.5 and RCP 8.5) and four future timeframes (2016–2045, 2036–2065, 2056–2085, and 2075–2104), totalling 64 climate futures. Future design rainfalls were computed for Annual Exceedance Probabilities (AEPs) of 1%, 2%, 5%, and 10%, spanning durations from 1 to 7 days. For each climate future, an Annual Maximum Series was established, and a Gumbel distribution was applied to estimate precipitation for various AEPs. Comparisons were made with baseline (stationary) design rainfalls and those derived from Australian Rainfall & Runoff (AR&R) methodology based on temperature scale factors. GCM-derived design rainfalls indicate a general reduction in depths for most durations and AEPs under both RCP scenarios. Specifically, RCP 4.5 demonstrated significant reductions in design rainfalls for the 1% AEP, ranging from −9.61% (1-day duration) to −21.40% (7-day duration). Similarly, RCP 8.5 showed decreased depths, except for 1-day, 2-day, and 3-day design rainfalls in the 2075–2104 timeframe, which exhibited marginal increases. AR&R methodology yielded substantially higher design rainfalls, with increases reaching +11.6% for 1% AEP and 10% AEP. While GCM-derived rainfalls imply adequacy of current drainage infrastructure, AR&R methodology suggests a more conservative estimate, emphasizing the need for cautious climate data interpretation.Full Tex
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
[Newspaper Clipping: Author Claims Evidence of Second JFK Assassin #1]
Newspaper article titled "Author Claims Evidence of Second JFK Assassin." The article states that author Richard J. Whalen concluded "that there is circumstantial evidence to support the theory of a second assassin in the shooting of President John F. Kennedy.
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
The desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
Jersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
We report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either

Takahashi.</p> <p> <i>Description</i></p> <p>Trunk (Figure 6A) slender, completely segmented. Lateral processes twice as long as their diameters, separated by their lengths, each with single tiny distal seta without protuberance; some lateral processes lack setae. Neck more than three times as long as wide. Ocular tubercle in midline between anterior margins of first lateral processes, shorter than its basal diameter, dome-shaped, tilted toward posterior, with small distal knob; eyes pigmented and situated halfway up ocular tubercle. Abdomen height about three times basal diameter, cylindrical proximally, slightly tapering and blunt distally, without setae. Proboscis long, straight, cylindrical, almost as long as neck, less than three times as long as wide, swollen distally and centrally, without setae; lips flat.</p> <p>Chelifore scapes (Figure 6A) about seven times as long as wide, with several dorsal setae, with rows of setae dorsodistally and laterodistally. Chelae (Figure 6B) slightly curved inwards; palms cylindrical, equal to finger length, with many short setae; movable finger with 39 pointed teeth endally; immovable finger same length as movable finger, with 34 teeth; fingers crossed at tips.</p> <p>Palps (Figure 6C) slender, five-segmented; second segment longest; third segment 0.7 times length of second segment and 1.2 times length of fifth segment; fifth segment 1.5 times length of fourth segment; all segments except for first have setae over entire surface, each segment more setose than next proximal segment.</p> <p>Ovigers (Figure 6D) 10-segmented; fifth segment longest, 1.3 times length of fourth, gently curved, swollen distally, distal width 1.5 times basal width, with moderately long setae dorsally, smaller setae ventrally, and several distal setae longer than dorsal setae; first segment glabrous; second and third segments with a few setae; fourth segment with setae ventrally and dorsodistally; sixth segment less than half length of fifth, with many setae over entire surface except ventrally; distal four segments (Figure 6E) with several setae ectally and laterally, and with compound spines having three denticles per side; eighth and ninth segments equal in length, 0.6 times as long as seventh segment; terminal segment slightly shorter than eighth and ninth segments; terminal claw equal to or slightly shorter than terminal segment, with seven tooth serrations; spine formula 10: 6: 6: 6:: 7.</p> <p>Legs (Figure 6F) long, slender, with many small setae and a few longer distal setae on every segment, each segment after second coxa narrower and more setose than preceding segment, propodus about one-third the width of coxa and of femur. Second coxa slightly longer than first and third coxae combined; femur 0.7 times length of first tibia; second tibia longest, less than 1.5 times length of first tibia. Cement gland pores open on ventral side of femur and first tibia, numbering six to 41 in a line on femur and seven to 31 on first tibia. Tarsus and propodus length (Figure 6G) subequal. Main claw slender, longer than half propodus length; auxiliary claws short, about a quarter as long as main claw.</p> <p> <i>Remarks</i></p> <p> Our specimens correspond well with the original description of <i>N</i>. <i>ortmanni</i> by Helfer (1938) and the re-description by Nakamura (1987) in the morphology of chelifores, ovigers and palps, and in the length ratios of tarsus to propodus and of auxiliary claws to main claw. Our specimens, however, have a more elongate trunk than that described by these two authors.</p> <p> <i>Nymphon ortmanni</i> is most similar to <i>N</i>. <i>japonicum</i> in the structures of chelifores, palps, and ovigers, shape of the trunk and body size. However, the two species can be easily distinguished by the proportions of the claws. <i>Nymphon ortmanni</i> has a main claw that is over half the length of the propodus, and relatively small auxiliary claws that are a quarter the length of main claw, whereas <i>N</i>. <i>japonicum</i> has a smaller main claw that is less than half the length of the propodus, and longer auxiliary claws that are nearly or over half the length of the main claw.</p> <p> Careful re-examination of the paratype specimens of <i>N</i>. <i>ortmanni</i> revealed that this species has multi-pored cement glands on both the femur and first tibia. The number of pores, which seems to depend on segment length, is 24–41 on the femur and 22–31 on the first tibia of paratype males, compared with six to 26 on the femur and seven to 11 on the first tibia in our specimens.</p> <p> <i>Nymphon ortmanni</i> was originally described from Sagami Bay, central Japan (Helfer 1938), and was subsequently found at various sites from Sagami Bay to Tsugaru Strait, northern Japan. Hedgpeth (1949) noted concerning the geographical distribution of pycnogonids that “a few endemic species are found along the shore both north and south of 35 ◦ N, however, on the whole species do not cross this boundary”. Since his study, three species of <i>Nymphon</i> (<i>N</i>. <i>gunteri</i> Hedgpeth, 1949, <i>N</i>. <i>japonicum</i> and <i>N</i>. <i>kodanii</i> Hedgpeth, 1949) have been found to occur across the 35 ◦ N parallel; our study adds <i>N</i>. <i>ortmanni</i> as the fourth.</p> <p>This species is endemic to Japan. It was previously known from Tsugaru Strait to Suruga Bay at depths of 75–450 m, (Utinomi 1971; Nakamura and Child 1983, 1991); our study extends its known distribution southward to Okinawa and its minimum known depth to 51 m. Our specimens represent the first record from subtropical waters.</p>Published as part of <i>Takahashi, Yoshie, Kajihara, Hiroshi & Mawatari, Shunsuke F., 2012, Sea spiders of the genus Nymphon (Arthropoda: Pycnogonida) from waters around the Nansei Islands, Japan, pp. 1337-1358 in Journal of Natural History 46 (21 - 22)</i> on pages 1349-1352, DOI: 10.1080/00222933.2012.655797, <a href="http://zenodo.org/record/5200053">http://zenodo.org/record/5200053</a>
