An Analytical Framework to Describe the Interactions Between Individuals and a Continuum

We consider a discrete set of individual agents interacting with a continuum. Examples might be a predator facing a huge group of preys, or a few shepherd dogs driving a herd of sheeps. Analytically, these situations can be described through a system of ordinary differential equations coupled with a scalar conservation law in several space dimensions. This paper provides a complete well posedness theory for the resulting Cauchy problem. A few applications are considered in detail and numerical integrations are provided

Doing gender locally: The importance of ‘place’ in understanding marginalised masculinities and young men’s transitions to ‘safe’ and successful futures

Observable anxieties have been developing about the position of boys and young men in contemporary society in recent years. This is expressed as a crisis of masculinity, in which place is often implicitly implicated, but is rarely considered for its role in the shaping of young men’s practices, trajectories and aspirations. Drawing on research conducted with young people who accessed a range of social care support services, this article argues that transition means different things for young men in different locales and that local definitions of masculinity are required to better understand young men’s lives and the opportunities available to them. The authors argue that home life, street life, individual neighbourhoods, regions and nations all shaped the young men’s identities and the practices they (and the staff working with them) drew on in order to create successful futures and ‘safe’ forms of masculinity. It is suggested that this place-based approach has the potential to re-shape the ‘crisis’ discourse surrounding masculinity and the anxieties associated with young men

Transoral robotic surgery (TORS): a new tool for high risk tracheostomy decannulation

La decannulazione è sempre stata considerata una procedura con un certo grado di rischio, specie nei pazienti con ridotti diametri delle via aeree, come nel caso della sindrome delle apnee ostruttive (OSA). Presentiamo 4 casi nei quali la chirurgia robotica transorale (TORS) ha permesso un appropriato management di pazienti tracheotomizzati da divers mesi. Gli obiettivi del nostro lavoro sono: 1. Dimostrare come il team otorinolaringoiatrico possa favorire il riconoscimento di pazienti ad alto rischio di decannulazione inefficace e 2. Evidenziare il ruolo nella TORS nel trattamento dellipertrofia della base della lingua, responsabile dellostruzione delle vie aeree superiori. Dalla nostra esperienza la TORS appare una tecnica efficace nella decannulazione di pazienti affetti da ipertrofia della base della lingua e da epiglottide flottante

Effects of environment on quality of tomato transplanting plants

Com a finalidade de verificar o efeito da adubação nitrogenada e intensidade luminosa sobre a qualidade das mudas de tomateiro cv Roma VF, foi instalado um experimento em con dições de estufa de vidro, no Setor de Horticultura da ESALQ, Piracicaba (SP). Os tratamentos consistiram em plantas sombreadas, com e sem adubação. Foram observados a altura, diâmetro do caule, e desenvolvimento do sistema radicular das mudas após 32 dias de germinação e os níveis de carboidratos e nitrato no caule. Dos resultados concluiu-se que a adubação nitrogenada na fase de muda é muito importante para se obter plantas sadias e fortes e em condições sombreadas, com adubação nitrogenada, as mudas são maiores, com alto teor de nitrato, enquanto que em condições de pleno sol e adubada, elas possuem maior diâmetro e sistema radicular mais desenvolvido.In order to study the effects of shading and unshading combined with N fertilizing on tomato transplanting plants, an experiment in greenhouse conditions was carried on. It was concluded that N is important to produce healthy and strong plants. Under shading plus N fertilization, plants are taller and have high nitrate contents, while under unshading plus N fertilization, plants have higher diameter and more developed root system

The development of children's comprehension and appreciation of riddles

Humor appreciation and understanding is important for children’s social relationships. The current study examined the associations between riddle comprehension, riddle appreciation, and smiling/laughter in children from a wide age-range aged 4 to 11 years old, as well as how cognitive processing style relates to riddle comprehension. Style was distinguished between local and global language processing at the sentence level. The results showed that only children above the age of 8 years old showed a reliable relationship between humor comprehension and smiling/laughter. These findings show that laughter should not be taken as an automatic indicator of explicit understanding. In addition, higher vocabulary ability was independently associated with better humor comprehension. This demonstrates a separable role language proficiency in humor comprehension and suggests avenues for future research in atypical populations known to have difficulties in this area

Lifetime measurement in excited and yrast superdeformed bands in Hg194

Nuclear level lifetimes have been measured in two superdeformed bands in Hg194 using the Doppler-shift attenuation method. Average transition quadrupole moments derived from the lifetimes of an excited and yrast superdeformed bands are Qt=17.6(30) and 17.2(20)eb, respectively. The Doppler shifts of the excited band relative to the yrast band indicate a slight difference in quadrupole moments [+4(5)%], assuming similar side feeding..ul2 These results imply that the second well is stable and rigid with respect to the particle excitation responsible for this excited band

Projected WIMP sensitivity of the LUX-ZEPLIN dark matter experiment

LUX-ZEPLIN (LZ) is a next-generation dark matter direct detection experiment that will operate 4850 feet underground at the Sanford Underground Research Facility (SURF) in Lead, South Dakota, USA. Using a two-phase xenon detector with an active mass of 7 tonnes, LZ will search primarily for low-energy interactions with weakly interacting massive particles (WIMPs), which are hypothesized to make up the dark matter in our galactic halo. In this paper, the projected WIMP sensitivity of LZ is presented based on the latest background estimates and simulations of the detector. For a 1000 live day run using a 5.6-tonne fiducial mass, LZ is projected to exclude at 90% confidence level spin-independent WIMP-nucleon cross sections above 1.4 × 10-48cm2 for a 40 GeV/c2 mass WIMP. Additionally, a 5σ discovery potential is projected, reaching cross sections below the exclusion limits of recent experiments. For spin-dependent WIMP-neutron(-proton) scattering, a sensitivity of 2.3 × 10−43 cm2 (7.1 × 10−42 cm2) for a 40 GeV/c2 mass WIMP is expected. With underground installation well underway, LZ is on track for commissioning at SURF in 2020

Volume I. Introduction to DUNE

The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay—these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. The Deep Underground Neutrino Experiment (DUNE) is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. This TDR is intended to justify the technical choices for the far detector that flow down from the high-level physics goals through requirements at all levels of the Project. Volume I contains an executive summary that introduces the DUNE science program, the far detector and the strategy for its modular designs, and the organization and management of the Project. The remainder of Volume I provides more detail on the science program that drives the choice of detector technologies and on the technologies themselves. It also introduces the designs for the DUNE near detector and the DUNE computing model, for which DUNE is planning design reports. Volume II of this TDR describes DUNE\u27s physics program in detail. Volume III describes the technical coordination required for the far detector design, construction, installation, and integration, and its organizational structure. Volume IV describes the single-phase far detector technology. A planned Volume V will describe the dual-phase technology

Deep Underground Neutrino Experiment (DUNE), far detector technical design report, volume III: DUNE far detector technical coordination

The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay—these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. The Deep Underground Neutrino Experiment (DUNE) is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. Volume III of this TDR describes how the activities required to design, construct, fabricate, install, and commission the DUNE far detector modules are organized and managed. This volume details the organizational structures that will carry out and/or oversee the planned far detector activities safely, successfully, on time, and on budget. It presents overviews of the facilities, supporting infrastructure, and detectors for context, and it outlines the project-related functions and methodologies used by the DUNE technical coordination organization, focusing on the areas of integration engineering, technical reviews, quality assurance and control, and safety oversight. Because of its more advanced stage of development, functional examples presented in this volume focus primarily on the single-phase (SP) detector module
