    This project defines and builds a comprehensive data platform that records data for bee management actions and natural world inputs and the performance results flowing from those actions and conditions. The collection and management of this data will allow for the application of advanced data analytics techniques that will lead to a better understanding and evaluation of the economic and best management practices for commercial beekeepers and growers of pollinated crops. Together these will lead to a better design and utilization of smart hive technologies for hive management and the development of an intelligent hive management system

    The ratios of branching fractions R(D)B(BˉDτνˉτ)/B(BˉDμνˉμ)\mathcal{R}(D^{*})\equiv\mathcal{B}(\bar{B}\to D^{*}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(\bar{B}\to D^{*}\mu^{-}\bar{\nu}_{\mu}) and R(D0)B(BD0τνˉτ)/B(BD0μνˉμ)\mathcal{R}(D^{0})\equiv\mathcal{B}(B^{-}\to D^{0}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(B^{-}\to D^{0}\mu^{-}\bar{\nu}_{\mu}) are measured, assuming isospin symmetry, using a sample of proton-proton collision data corresponding to 3.0 fb1{ }^{-1} of integrated luminosity recorded by the LHCb experiment during 2011 and 2012. The tau lepton is identified in the decay mode τμντνˉμ\tau^{-}\to\mu^{-}\nu_{\tau}\bar{\nu}_{\mu}. The measured values are R(D)=0.281±0.018±0.024\mathcal{R}(D^{*})=0.281\pm0.018\pm0.024 and R(D0)=0.441±0.060±0.066\mathcal{R}(D^{0})=0.441\pm0.060\pm0.066, where the first uncertainty is statistical and the second is systematic. The correlation between these measurements is ρ=0.43\rho=-0.43. Results are consistent with the current average of these quantities and are at a combined 1.9 standard deviations from the predictions based on lepton flavor universality in the Standard Model.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-039.html (LHCb public pages

    Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

    Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

    Generational Trauma and Nationalist Rhetoric as a Basis for Genocide

    No full text
    The atrocities that were committed in Rwanda, Bosnia and Armenia could not have been possible without the participation or support of those populations. How is it possible that humans can be convinced to carry out unimaginable atrocities against fellow men and women, many of whom they called friends and neighbors? I will be using the three instances of genocide mentioned above as my case studies to test my hypothesis and determine how trauma and rhetoric led to each genocide. My thesis will approach this question through studying governments, human behavior, pre-existing conditions, historical trauma, and violent rhetoric to attempt to draw parallels and pinpoint exactly which factors are universal precursors and contributors to genocide. These three cases of genocide provide a diverse range of geographic locations, ethnicities, religions, and socio-economic categories in order to show that genocides are not dependent on these factors and have similar underpinnings despite the variations of the factors above. I will be analyzing how genocide can be perpetuated as the perception of certain groups is changed by rhetoric to dehumanize or have them be considered a threat to the fabric of society. Genocide is more than murder, it is the desire to exterminate an entire people, their culture, their history, and their ability to reproduce and survive. This should never be taken lightly, but our modern globalized world has done little to prevent the continuation of genocides. This must change if we are to have any hope of preventing future brutalities

    Nuclear Proliferation and Presidential Rhetoric During the Cold War

    No full text
    Delivered on June 10, 1963, in the midst of the Cold War, President John F. Kennedy\u27s speech at American University offered a new approach to the United States\u27 relationship with the Soviet Union as well as with nuclear weapons. This speech represented a major shift in US foreign policy following the failed Bay of Pigs invasion and the Cuban Missile Crisis. Not only did this speech alter the 1960\u27s, but it also laid the groundwork for future arms deals and inspired future generations to strive for peace. Our presentation will analyze the presidential rhetoric of the Cold War and its effects, and how it compares to the presidential rhetoric of today
