Food for Thought: Genetically Modified Seeds as De Facto Standard Essential Patents

For several years, courts have been improperly calculating damages in cases involving the unlicensed use of genetically-modified (GM) seed technology. In particular, when courts determine patent damages based on the hypothetical negotiation method, they err in exaggerating these damages to a point where no rational negotiator would agree. In response, we propose a limited affirmative defense of an implied license due to the patent’s status as a de facto standard essential patent. To be classified as a de facto standard essential patent, the farmer must prove three elements that reflect the peculiarities of GM seeds used in farming: (1) dominance, (2) impracticability, and (3) necessary to fulfill a basic need. Based on the approaches used by courts and standard setting organizations in licensing standard essential patents in technological fields such as cell phones and software, designation of some GM seeds as standard essential patents allows the courts to imply a license from patentees to farmers on reasonable and non-discriminatory (RAND) terms. Doing so shifts the case from a tort-based patent infringement suit to a breach of contract dispute and alters the damages regime from one based in compensation, deterrence, and punishment (a tort approach) to one based solely in compensation (a contractual approach). As a result of this novel proposal, the damages calculations in these suits return to economic reality

Integration of Direct-Write (DW) and Ultrasonic Consolidation (UC) Technologies to Create Advanced Structures with Embedded Electrical Circuitry

In many instances conductive traces are needed in small, compact and enclosed areas. However, with traditional manufacturing techniques, embedded electrical traces or antenna arrays have not been a possibility. By integrating Direct Write and Ultrasonic Consolidation technologies, electronic circuitry, antennas and other devices can be manufactured directly into a solid metal structure and subsequently completely enclosed. This can achieve a significant reduction in mass and volume of a complex electronic system without compromising performance.Mechanical Engineerin

Examining UAS Employment Expectations and Requirements

Unmanned aircraft system (UAS) technology is radically changing how organizations, such as government agencies, non-profit corporations, and companies, apply aviation resources. Unmanned aviation is supporting improved efficiency, expanded capability, and heightened reliability through an increasing number of uses relating to: a) research and development and training-education, b) event filming, c) industrial, utility, and environmental projects, d) real estate, e) construction activities, f) agricultural, g) press and media, and h) state/local emergency services. The increasing application, and subsequent operational growth, is occurring in response to maturing technology, refined operational management and permissibility, innovative concept development, demonstrated capability, enhanced supportability, and the availability of specialized education and training opportunities. Technological advancement, regulatory changes, economic development, and widespread adoption of this technology is also leading to an observable growth of related employment opportunities. The Federal Aviation Administration has indicated that there are currently 116,027 remote pilots certified to operate small UAS in the National Airspace System, with growth to almost 350,000 by 2023. The examination of current career opportunities, in connection with commonly advertised job types and the associated roles and responsibilities, could better inform future UAS curricula design and enhancement efforts. This paper and associated presentation will feature an in-depth examination of such positions to categorize type and summarize prevalent attributes, while also highlighting notable features such as popular hiring locations, salary estimation, and experience-levels. The intent is to provide a detailed summary of hiring expectations and identify potential opportunities for improving academic alignment and career development efforts

Gas-phase formation and spectroscopic characterization of the disubstituted cyclopropenylidenes c-C3(C2H)2, c-C3(CN)2, and c-C3(C2H)(CN)

Aims. The detection of c-C3HC2H and possible future detection of c-C3HCN provide new molecules for reaction chemistry in the dense ISM where R-C2 and R-CN species are prevalent. Determination of chemically viable c-C3HC2H and c-C3HCN derivatives and their prominent spectral features can accelerate potential astrophysical detection for this chemical family. This work will characterize three such derivatives: c-C3(C2H)2, c-C3(CN)2, and c-C3(C2H)(CN). Methods. Interstellar reaction pathways of small carbonaceous species are well-replicated through quantum chemical means. Highly-accurate cc-pVX Z-F12/CCSD(T)-F12 (X =D,T) calculations generate the energetics of chemical formation pathways as well as the basis for quartic force field and second-order vibrational perturbation theory rovibrational analysis of the vibrational frequencies and rotational constants of the molecules under study. Results. The formation of c-C3(C2H)2 is as thermodynamically and, likely, stepwise favorable as the formation of c-C3HC2H, rendering its detectability to be mostly dependent on the concentrations of the reactants. c-C3(C2H)2 and c-C3(C2H)(CN) will be detectable through radioastronomical observation with large dipole moments of 2.84 D and 4.26 D, respectively, while c-C3(CN)2 has an exceedingly small and likely unobservable dipole moment of 0.08 D. The most intense frequency for c-C3(C2H)2 is ν2 at 3316.9 cm−1 (3.01 µm) with an intensity of 140 km mol−1. c-C3(C2H)(CN) has one frequency with a large intensity, ν1, at 3321.0 cm−1 (3.01 µm) with an intensity of 82 km mol−1. c-C3(CN)2 lacks intense vibrational frequencies within the range that current instrumentation can readily observe. Conclusions. c-C3(C2H)2 and c-C3(C2H)(CN) are viable candidates for astrophysical observation with favorable reaction profiles and spectral data produced herein, but c-C3(CN)2 will not be directly observable through any currently-available remote sensing means even if it forms in large abundances

Landfast Sea Ice Conditions in the Canadian Arctic: 1983 – 2009

We used Canadian Ice Service (CIS) digital charts from 1983 to 2009 to create a climatology of landfast sea ice in the Canadian Arctic. The climatology characterized the spatial distribution and variability of landfast ice through an average annual cycle and identified the mean onset date, breakup date, and duration of landfast ice. Trends in date and duration of onset and breakup were calculated over the 26-year period on the basis of CIS regions and sub-regions. In several sub-regions— particularly in the Canadian Arctic Archipelago—we calculated significant trends towards later landfast ice onset or earlier breakup, or both. These later onset and earlier breakup dates translated into significant decreases in landfast ice duration for many areas of the Canadian Arctic. For communities located in the most affected areas, including Tuktoyaktuk, Kugluktuk, Cambridge Bay, Gjoa Haven, Arctic Bay, and Pond Inlet, this shorter landfast ice season is of significant social, cultural, and economic importance. Landfast sea-ice duration in the interior of the Northwest Passage has not undergone any statistically significant decrease over the time series.Nous nous sommes appuyés sur les cartes numériques du Service canadien des glaces (SCG) pour les années 1983 à 2009 afin de produire la climatologie de la glace de mer de l’Arctique canadien. La climatologie permet de caractériser la distribution spatiale et la variabilité de la glace de mer au moyen d’un cycle annuel moyen, et de déterminer la date moyenne du commencement, la date de la débâcle et la durée de la glace de mer. Les tendances en matière de dates et de durées relativement au commencement et à la débâcle ont été calculées sur la période de 26 ans en fonction des régions visées par le SCG et des sous-régions. Dans plusieurs sous-régions — plus particulièrement dans l’archipel Arctique canadien — nous avons calculé d’importantes tendances indiquant des dates de commencement plus tardives de la glace de mer ou des dates de débâcle plus hâtives, ou les deux. Ces dates plus hâtives et plus tardives se traduisent par la réduction considérable de la durée de la glace de mer en maints endroits de l’Arctique canadien. Pour les localités situées dans la plupart des régions touchées, dont Tuktoyaktuk, Kugluktuk, Cambridge Bay, Gjoa Haven, Arctic Bay et Pond Inlet, cette saison de glace de mer plus courte revêt une grande importance sur les plans social, culturel et économique. Du point de vue statistique, la durée de la glace de mer à l’intérieur du passage du Nord-Ouest n’a pas connu de réduction importante au cours de cette période

An integrated system to survey boat-based recreational fishing in Western Australia 2011/12

The Department of Fisheries developed an integrated system involving several survey methods to provide a more robust approach for obtaining annual estimates of recreational catch by boat based fishers at both state-wide and bioregional levels. These surveys, which used the recently implemented Recreational Fishing from Boat Licence (RFBL) as the basis for sampling, were the most comprehensive ever conducted in Western Australia. They not only provided estimates of catch and effort but provided the information for the validation of these estimates by enabling comparisons across the various methods

Moderating Effects of Immunosuppressive Medications and Risk Factors for Post-Operative Joint Infection Following Total Joint Arthroplasty in Patients with Rheumatoid Arthritis or Osteoarthritis

Objective—Inconclusive findings about infection risks, importantly the use of immunosuppressive medications, in patients who have undergone large-joint total joint arthroplasty challenge efforts to provide evidenced-based perioperative total joint arthroplasty recommendations to improve surgical outcomes. Thus, the aim of this study was to describe risk factors for developing a postoperative infection in patients undergoing TJA of a large joint [total hip arthroplasty, total knee arthroplasty, or total shoulder arthroplasty] by identifying clinical and demographic factors, including the use of high risk medications (i.e., prednisone and immunosuppressive medications) and diagnoses (i.e., rheumatoid arthritis [RA], osteoarthritis [OA], gout, obesity, diabetes mellitus), that are linked to infection status, controlling for length of follow-up. Methods—A retrospective, case-control study (N = 2,212) using de-identified patient health claims information from a commercially-insured, U.S. dataset representing 15 million patients annually (January 1, 2007 - December 31, 2009) was conducted. Descriptive statistics, t-test, chi-square test, Fisher\u27s exact test, and multivariate logistic regression were used. Results—Male gender (OR = 1.42; p \u3c .001), diagnosis of RA (OR = 1.47; p = .031), diabetes mellitus (OR = 1.38, p = .001), obesity (OR = 1.66, p \u3c .001) or gout (OR = 1.95; p = .001), and a prescription for prednisone (OR = 1.59; p \u3c .001) predicted a post-operative infection following total joint arthroplasty. Persons with post-operative joint infections were significantly more likely to be prescribed allopurinol (p = .002) and colchicine (p = .006; no significant difference was found for the use of specific disease modifying anti-rheumatic drugs and TNF-α inhibitors. Conclusion—High-risk, post-operative joint infection groups were identified allowing for precautionary clinical measures to be taken

Micrometeorological and Thermal Control of Frost Flower Growth and Decay on Young Sea Ice

Frost flowers are transient crystal structures that form on new and young sea ice surfaces. They have been implicated in a variety of biological, chemical, and physical processes and interactions with the atmosphere at the sea ice surface. We describe the atmospheric and radiative conditions and the physical and thermal properties of the sea ice and atmosphere that form, decay, and destroy frost flowers on young sea ice. Frost flower formation occurred during a high-pressure system that caused air temperatures to drop to −30˚C, with relative humidity of 70% (an undersaturated atmosphere), and very calm wind conditions. The sea ice surface temperature at the time of frost flower initiation was 10˚–13˚C warmer than the air temperature. Frost flowers grew on nodules raised above the mean surface height by 5 mm, which were 4˚–6˚C colder than the bare, brine-wetted, highly saline sea ice surface that provided the necessary moisture. The cold nodules created potential water vapour supersaturation zones above them with respect to air over the brine skim. Frost flowers formed and grew overnight in the absence of shortwave radiation, while the net longwave radiation was negative and dominated the net all-wave radiation balance at the surface. The observed crystal habits of the frost flowers were long needles, betraying their origin from the vapour phase at temperatures between −20˚C and −30˚C. After a night of growth, frost flowers decayed in association with increased solar radiation, a net surface radiation balance of 0 W m-2, increased air and surface temperatures, increased wind speed, and decreased relative humidity. We hypothesize that these conditions increased vertical mixing, which eroded near-surface water vapour saturation and initiated sublimation. The frost flowers finally were rapidly destroyed by snowfall.Les fleurs de glace sont des structures cristallines transitoires qui se forment sur des surfaces de glace de mer nouvelles et jeunes. Elles découlent de divers processus et interactions biologiques, chimiques et physiques avec l’atmosphère, à la surface de la glace de mer. Nous décrivons les conditions atmosphériques et radiatives de même que les propriétés physiques et thermiques de la glace de mer qui forment, détériorent et détruisent les fleurs de glace sur la jeune glace de mer. La formation de fleurs de glace s’est produite lorsqu’un système de haute pression a fait baisser les températures de l’air à −30 ˚C, avec une humidité relative de 70 % (atmosphère sous-saturée) et un régime des vents très calme. À l’amorçage des fleurs de glace, la température à la surface de la glace de mer était de 10˚ à 13 ˚C plus chaude que la température de l’air. Les fleurs de glace se sont formées sur des nodules élevés au-dessus de la hauteur moyenne de la surface dans une mesure de 5 mm, ce qui était entre 4˚ et 6 ˚C plus froid que la surface de glace de mer brute, saumurée et fortement saline qui a fourni l’humidité nécessaire. En ce qui a trait à l’air au-dessus de l’écume de saumure, les nodules de froid ont créé des zones potentielles de sursaturation de vapeur d’eau au-dessus. Des fleurs de glace se sont formées et ont grossi pendant la nuit, en l’absence de rayonnement de courtes longueurs d’onde, tandis que le rayonnement net de grandes longueurs d’onde était négatif et dominait l’équilibre du rayonnement net de toutes ondes à la surface. L’habitus cristallin observé dans les fleurs de glace prenait la forme de longues aiguilles, trahissant son origine de la phase vapeur à des températures variant de −20 ˚C à −30 ˚C. Après une nuit de croissance, les fleurs de glace se sont détériorées en présence du rayonnement solaire accru, du bilan radiatif de la surface de 0 W m-2, des températures accrues de l’air et de la surface, de la plus grande vitesse du vent et de l’humidité relative réduite. Nous formulons l’hypothèse que ces conditions ont eu pour effet d’augmenter le mélange vertical, ce qui a érodé la saturation de vapeur d’eau près de la surface et déclenché la sublimation. Par la suite, les fleurs de glace ont été rapidement détruites par la chute de neige
