Grainy visuals and tape distortions blanket one video showing a "typical" middle-class suburban breakfast table featuring milk, orange juice, and of course, Eggos before cutting to a screen that ...reads "One Eggo Can Change Everything." The only difference between the Limited Edition 1985 Graphics Eggos and regular 2019 Eggos is the package itself, and thus, in relation to the function or quality of the product, nothing substantial is different. Though there is potential overlap between lived experience and the experiences represented in cultural ephemera for viewers of a certain age, it is significant that the lens the show provides for those viewers to reminisce about their lived experiences is explicitly tropological and mediated-it is accessed, if at all, through reference, genre, narrative structure, sound, and visual style. A gloss of the interpretive frames into which viewers have placed the show offers a glimpse into this myriad and often contradictory landscape: the series has been seen as a distinctly celebratory, nostalgic vision of the 1980s and its media (McCarthy; Genzlinger; Chaney); as a critique of the 1980s, Reaganism, and middle-class suburbia (Butler; Smith; Burges; Nussbaum); as an allegory or metaphor for the traumatic experience of coming-of-age and entering into a world of adult conformity (Khan; Butler); as a form of digital gothic or an expression of longing for the analog in a digital world (Landrum; Rust); as an exploration of queerness past and present as well as a critique of straight nostalgia (Burges and Middleton; Roach; Berns et al.; Briefel); as an example of a distinctly white nostalgia (Bering-Porter; Giovannone); and as a critique of white nostalgia (Reich).
This paper describes the initial results of precipitation estimates from the Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) ...Millimeter-wave Sounder (TMS) using the Precipitation Retrieval and Profiling Scheme (PRPS). The TROPICS mission consists of a Pathfinder cubesat and a constellation of six cubesats, providing a low-cost solution to the frequent sampling of precipitation systems across the Tropics. The TMS instrument is a 12-channel cross-track scanning radiometer operating at frequencies from 91.655 to 204.8 GHz, providing similar resolutions to current passive microwave sounding instruments. These retrievals showcases the potential of the TMS instrument for precipitation retrievals. The PRPS has been modified for use with the TMS using a database based upon observations from current sounding sensors. The results shown here represent the initial post-launch version of the retrieval scheme, as analyzed for the Pathfinder cubesat launched on June 30, 2021. In terms of monthly precipitation estimates the results fall within the mission specifications and are similar in performance t
A millimeter (mm) wave amplifier that combines both high-power output and a wide bandwidth would enable dramatic improvements in areas where high-power radio signals with significant information ...content are required. However, to date, the only available devices are either high-power vacuum electronic devices with limited bandwidths, or larger bandwidth semiconductor amplifiers with low-power output. Here, we show a new design of a vacuum electronic traveling-wave tube amplifier that has a measured output power of 107 W with a 3-dB bandwidth of 6 GHz centered on 200 GHz. The power-bandwidth product of this amplifier is 642 W-GHz. These results provide a demonstration of a high-power mm-wave source with significant bandwidth. This device is readily scalable to other frequency bands, particularly those in the mm- and sub-mm-wave frequency bands from 100 GHz to 1 THz.
Gastrointestinal stromal tumors (GISTs) are rare tumors of the digestive tract, often found incidentally on imaging. Although these tumors possess malignant potential, splenic encapsulation has not ...yet been described in the literature. A 74-year-old male fell and suffered blunt abdominal trauma followed by a 20-pound weight loss, early satiety, and left-sided abdominal pain. Computed tomography (CT) imaging showed splenomegaly with gastric compression. At the time of surgery, it was felt that this was a neoplastic process. He underwent a subsequent splenectomy and en bloc wedge gastrectomy. Further analysis revealed a GIST, of gastric origin, encapsulating the spleen and invading the diaphragm. Specimen stained strongly positive for the cluster of differentiation (CD) 117 mutation. Following recovery from the operation, the patient was started on Imatinib (Gleevec) therapy and will continue treatment for five years. Splenic metastasis and contiguous spread are rare sequelae of GISTs. While these tumors hold the potential for metastasis, the primary locations are the liver and peritoneum. This case illustrates the importance of considering malignancy as a possible underlying etiology when presented with an apparent splenic hematoma and abdominal pain. Since this patient possessed the CD117 mutation, Imatinib is an appropriate therapeutic choice in addition to surgical resection of the neoplasm.
Over the last several decades, a wealth of observations of gamma-ray emission at TeV energies has increased our understanding of the extreme physical processes happening in our Galaxy. However, ...fundamental questions remain unanswered. To how high an energy are cosmic rays able to be accelerated in our galaxy, and how does that connect with the features observed in the cosmic-ray energy spectrum such as the "knee'', the "second knee'', and the "ankle''? Answers to these questions can be searched for by extending gamma-ray observations to higher energies. As the only experiment sensitive to PeV gamma rays in the Southern Hemisphere, the IceCube observatory can address these issues from a unique perspective. In this work, gamma-ray candidate events are selected from data observed by the surface and in-ice arrays of the IceCube observatory. This is accomplished by leveraging characteristic properties of gamma-ray induced air showers such as low muonic content and a deep shower maximum. Using five years of data, several searches for gamma-ray emission using unbinned likelihood methods are presented. The results of all searches are consistent with background, resulting in 90% flux upper limits that are the most stringent ever placed on PeV emission. The limits set on PeV gamma-ray point sources constrain, for the first time, the energy extension of a power-law flux for sources observed by HESS to have no break in their energy spectrum at TeV energies. Additionally, the resulting limit set by a search for an angular-integrated diffuse flux from the Galactic plane provides an upper bound useful for constructing Galactic cosmic-ray transport models.
Using the PolyStrata® 3D additive fabrication process, a novel 16-Way solid state power amplifier at Gband frequency range is demonstrated. InP DHBT PA MMICs, with an excess of 80 mW output power and ...>15 dB small signal gain, are used in this SSPA. To connect the MMICs to the 16-way splitter-combiner network, a micromachined WR4 E-probe to CPW transition was developed. These transitions use micro-length-wire-bonds exhibiting capability at sub-mmw frequencies. The broadband transitions showcase <;0.5 dB insertion loss and exhibit tight tolerances due to the batch additive manufacturing process. The SSPA was assembled using 16 mounted MMICs with transitions and demonstrated >11 dB small signal gain from 200-230 GHz. Large signal characterization showcased high saturated output power of 580 mW at 200 GHz, 820 mW at 216 GHz, 680 mW at 225 GHz and 380 mW at 230 GHz in an ultra-compact volume of 45 cm3 demonstrating a functional power density of >18 mW/cm3. Nuvotronics measured 823 mW at 216 GHz representing a 15.9% increase to the state of the art for a power module above 210 GHz, while reducing by half the number of MMICs required as compared to other approaches.
This paper reports a wideband MMIC low noise amplifier using a 50nm L g E-mode InGaAs PHEMT technology. It demonstrates simultaneous 22dB S21 gain and 1.0dB noise figure at 24GHz operation. The MMIC ...was designed for 18-35GHz bandwidth; however, noise figure is low and gain is appreciable from 4-40GHz. The amplifier survived being separately subjected to high-power bursts (18dBm P in , 60-sec), and elevated temperature burn-in (85°C for 24-hours) to verify its power handling capability and long-term reliability. The overall amplifier performance, yield, and reliability show that this InGaAs PHEMT technology has the requisite figures-of-merits to advance receiver system performance in hostile environments, as well as the increasingly more demanding commercial environment.
