    Abstract While historical studies of urbanisation tend to focus on the morphological and social changes of cities in transition, the very ontological status of the city itself can be historically located as an emergence dependent on specific political, cultural and technical conditions. This essay examines the attempt to create a single ‘Greater Boston’ entity at the end of the nineteenth century in response to forces which were ostensibly linking the separate communities of Massachusetts Bay together into a single whole. Using statistical methods, representational techniques, environmental transformation and appeals to community solidarity in order to make their case for the ‘real’ status of an enlarged Boston, this movement sheds light on how the limits of the ‘single’ city are historically contested. This essay argues against radical critiques of spatial boundedness and advances a theory of the ‘constitutive landscape’ which emphasises the way in which bounded, unitary geographic entities are historically made.

    Abstract The emergence in the United States of large-scale "megaregions" centered on major metropolitan areas is a phenomenon often taken for granted in both scholarly studies and popular accounts of contemporary economic geography. This paper uses a data set of more than 4,000,000 commuter flows as the basis for an empirical approach to the identification of such megaregions. We compare a method which uses a visual heuristic for understanding areal aggregation to a method which uses a computational partitioning algorithm, and we reflect upon the strengths and limitations of both. We discuss how choices about input parameters and scale of analysis can lead to different results, and stress the importance of comparing computational results with "common sense" interpretations of geographic coherence. The results provide a new perspective on the functional economic geography of the United States from a megaregion perspective, and shed light on the old geographic problem of the division of space into areal units.

    Abstract A six-year-old boy with Pallister-Killian syndrome (PKS) presented to the clinic with extensive lesions on his body (Figure 1). The patient was not born with the lesions but began developing them on the head and neck, extending to his lower extremities, at 2 years of age. These lesions had been evaluated by his primary care physician and were previously treated with desonide and ketoconazole cream with little improvement.

    Abstract The Robotics Systems Lab at Santa Clara University worked closely with Monterey Bay Aquarium Research Institute to design and modernize a safe, low-voltage remotely operated vehicle (ROV) and fabricate a shape memory alloy (SMA) triggered water sampler. The scope of this project was split into two parts. The first was to modernize an existing ROV frame and flotation device with low-cost, low-voltage components for depths up to 300ft. The second scope was to design and manufacture a 100ml water sampling system that was mostly mechanical. Due to the onset of COVID-19, the functionality and performance of the ROV was verified and confirmed through extensive Simulink simulations and calculations. The ROV is expected to perform at a translational speed of 2.8 ft/s and a vertical speed of 1.6 ft/s when deployed. The sampler was self-manufactured during the pandemic and successfully took a 135ml sample. After the modernization was complete, the controls were verified through a mass properties analysis and thruster mapping simulation.

    Abstract

    Granular parakeratosis, originally named axillary granular parakeratosis, is an uncommon disease with an unclear etiology. It is thought to result from defective processing of profillagrin to fillagrin, causing retention of keratohyaline granules in the epidermis. A myriad of causative factors has been proposed, including friction, moisture, heat, and contact irritants such as deodorants. We present a case in the inframammary area that resolved with mastopexy, further supporting the role of friction, moisture, and heat. Furthermore, we present electron microscopic evidence demonstrating non-degraded keratohyaline granules upon epidermal maturation. This entity, we believe, is reactive and represents a protective response of the body to moisture and heat.

    Abstract Gas dynamic virtual nozzles (GDVNs) produce microscopic flow-focused liquid jets and droplets and play an important role at X-ray free-electron laser (XFEL) facilities where they are used to steer a stream of hydrated biomolecules into an X-ray focus during diffraction measurements. Highly stable and reproducible microjet and microdroplets are desired, as are flexible fabrication methods that enable integrated mixing microfluidics, droplet triggering mechanisms, laser illumination, and other customized features. In this study, we develop the use of high-resolution 3D nano-printing for the production of monolithic, asymmetric GDVN designs that are difficult to fabricate by other means. We also develop a dual-pulsed nanosecond image acquisition and analysis platform for the characterization of GDVN performance, including jet speed, length, diameter, and directionality, among others. We show that printed GDVNs can form microjets with very high degree of reproducibility, down to sub-micron diameters, and with water jet speeds beyond 170 m/s.
