Global Web Page Design: Issues of Culture and Gender

The globalization of business has been of considerable interest in both the academic press (e.g., Ho, Ong, & Lee, 1997; Roberts & Hardt, 1997) and the practitioner press (e.g., Business Week Special Report, 1997). As a consequence of the growth in business across borders (e.g., Bartlett & Ghoshal, 1991), it is projected that the global workforce and consumer base will become increasingly diverse by the year 2000 (e.g., Human Resources Institute, 1991). Shaw (1990) has suggested there may be basic differences in how individuals from varying cultures collect, process, store, and use information. This implies that with regard to Web sites, perception and satisfaction differences may exist due to the socialization processes consumers may have experienced in their home countries

Hypergeometric decomposition of symmetric K3 quartic pencils

We study the hypergeometric functions associated to five one-parameter deformations of Delsarte K3 quartic hypersurfaces in projective space. We compute all of their Picard--Fuchs differential equations; we count points using Gauss sums and rewrite this in terms of finite field hypergeometric sums; then we match up each differential equation to a factor of the zeta function, and we write this in terms of global L-functions. This computation gives a complete, explicit description of the motives for these pencils in terms of hypergeometric motives.Comment: 70 pages, minor revision, to appear in Research in the Mathematical Science

Adversarial Assessment of the \u3ci\u3eF Prime\u3c/i\u3e Flight Software Framework: Findings and Recommendations

F Prime (F’) is a multi-platform, open-source flight software (FSW) framework developed by the Jet Propulsion Laboratory (JPL). F’ provides a highly capable, component-driven framework tailored towards, but not limited to, small-scale systems like CubeSats, SmallSats, and instruments. We conducted an adversarial assessment of F’ aimed at evaluating its security vulnerabilities. This preliminary assessment of F’ entailed a multi-stage simulation of a malicious actor’s activities, including open-source reconnaissance, passive and active reconnaissance, and exploitation. In this paper, we present our methodology and discuss the preliminary findings of this assessment, which highlighted several areas where F’ could be enhanced. These areas include the implementation of encryption for uplink and down-link communication, command authentication, the establishment of community standard cybersecurity practices, remediation of information leakage, and development of an opcode randomizer to provide secure defaults. We expect this preliminary work to inspire further detailed security assessments, and further the design and development of more secure and resilient flight software architectures

Zeta functions of alternate mirror Calabi–Yau families

We prove that if two Calabi-Yau invertible pencils have the same dual weights, then they share a common factor in their zeta functions. By using Dwork cohomology, we demonstrate that this common factor is related to a hypergeometric Picard–Fuchs differential equation. The factor in the zeta function is defined over the rationals and has degree at least the order of the Picard–Fuchs equation. As an application, we relate several pencils of K3 surfaces to the Dwork pencil, obtaining new cases of arithmetic mirror symmetry

Lick Tanks to Deliver Condensed Corn Distillers Solubles to Summer Grazing Beef Cows

This project was a preliminary investigation of the use of lick tanks to deliver condensed corn distillers soluble (CCDS) to summer grazing beef cows. During the first four paddock rotations, there was an increase in the amount of pasture dry matter consumed. As hot, dry weather persisted, forage quality and hence, pasture dry matter intake declined. This was accompanied by increased dry matter consumption of CCDS. Dry matter consumption of CCDS ranged from 2.66 pounds (14.8 pounds as-fed at the beginning of the project) to 8.11 pounds (30 pounds as-fed near the end of the project). Dietary intake of sulfur ranged from .43 to .62% of total diet dry matter. However, cattle health appeared to be unaffected by CCDS intake. Mold analyses for the CCDS are incomplete. Yeasts were consistently isolated from the assayed samples, but very few colonies of filamentous fungi (molds) were recovered. In fact, in most samples mold colonies were not detected. Mycotoxins were non-detectable for all mycotoxins analyzed, except fumonisins, which were present at low levels in all CCDS samples and likely came from the original grain. This data suggests that, if carefully managed, lick tanks may be used to deliver CCDS to summer grazing cows. However, the cows in this project had access to ample quantities of pasture and corn silage. A shortage of additional feedstuffs could alter the conclusions of this project

Mars Image Content Classification: Three Years of NASA Deployment and Recent Advances

The NASA Planetary Data System hosts millions of images acquired from the planet Mars. To help users quickly find images of interest, we have developed and deployed content-based classification and search capabilities for Mars orbital and surface images. The deployed systems are publicly accessible using the PDS Image Atlas. We describe the process of training, evaluating, calibrating, and deploying updates to two CNN classifiers for images collected by Mars missions. We also report on three years of deployment including usage statistics, lessons learned, and plans for the future.Comment: Published at the Thirty-Third Annual Conference on Innovative Applications of Artificial Intelligence (IAAI-21).

Airglow-CubeSat with Orientation Control by Aerospike Puff-jets

Observations of upper atmospheric emissions further the understanding of the effects of the chemiluminescent energetics of the Earth’s atmosphere. The Airglow- CubeSat will scan the desired altitudes of the mesosphere and the upper thermosphere. The resulting data is intended to help validate results collected from measurements taken from rocket profiles as well as the SABER/TIMED satellite. The Airglow-CubeSat will be monitoring the atomic oxygen green line at a wavelength of 557 nm. Research is also being conducted into the feasibility of using aerospike technology for altitude maintenance and satellite orientation control
