description: The Weather Research and Forecast model, augmented with a retrospective cost adaption algorithm, was assessed for forecast similarity to a synthetic flow-field generated by adding independent forcing terms to the horizontal momentum equations. The adapted solution was produced by employing synthetic horizontal wind speeds at 75 select locations. The results show a mean absolute wind speed difference of 0.053 m/s between the synthetic and adapted flow-fields. Furthermore, the mean difference between the input and output independent forcing terms over the entire simulation period is 0.06 Pam/s. This outcome demonstrates this approach could be used to improve real-time localized weather predictions.

description: Social networks initially had been places for people to contact each other, find friends or new acquaintances. As such they ever proved interesting for machine aided analysis. Recent developments, however, pivoted social networks to being among the main fields of information exchange, opinion expression and debate. As a result there is growing interest in both analyzing and integrating social network services. In this environment efficient information retrieval is hindered by the vast amount and varying quality of the user-generated content. Guiding users to relevant information is a valuable service and also a difficult task, where a crucial part of the process is accurately resolving duplicate entities to real-world ones. In this paper we propose a novel approach that utilizes the principles of link mining to successfully extend the methodology of entity resolution to multitype problems. The proposed method is presented using an illustrative social network-based real-world example and validated by comprehensive evaluation of the results.

description: Hydrocarbon aviation fuel is used as a coolant in the active regenerative cooling systems of hypersonic cruise vehicles. \\\\!hen the fuel is heated to above its critical point, hydrocarbon aviation fuel decomposes into hydrogen and various low-molecular weight hydrocarbons. This change in the composition of the fuel owing to thermal cracking affects the fluid flow and cooling performance within the active regenerative cooling system. In order to develop an effective active regenerative cooling system, it is essential to understand the thermal decomposition characteristics of hydrocarbon aviation fuel. Therefore, this study investigated the thermal cracking behaviours of two hydrocarbon aviation fuels (ndodecane (C12H2,) and exo-THDCPD (C10H16)) under a couple of conditions above their critical states using a batch reactor The experimental results revealed that the thermal cracking rate of the fuels increased as the reaction temperature increased and the thermal cracking behaviour differed depending on the substance. In addition, coking occurred under some high temperature conditions. The significance of the experimental results of this study is highlighted in the comprehensive description of the situations experienced by hydrocarbon aviation fuel in an active regenerative cooling system.

description: The field distribution in the vortex lattice of a pure niobium single crystal with an external field applied along a three-fold axis has been investigated by the transverse-field muon-spin-rotation (TF-$μ$SR) technique over a wide range of temperatures and fields. The experimental data have been analyzed with the Delrieu's solution for the form factor supplemented by phenomenological formulas for the parameters. This has enabled us to experimentally establish the temperatures and fields for the Delrieu's, Ginzburg-Landau's, and Klein's regions of the vortex lattice. Using the numerical solution of the quasiclassical Eilenberger's equation the experimental results have been reasonably understood. They should apply to all clean BCS superconductors. The analytical Delrieu's model supplemented by phenomenological formulas for its parameters is found to be reliable for analyzing TF-$μ$SR experimental data for a substantial part of the mixed phase. The Abrikosov's limit is contained in it.

Publisher: name: The Bovine Practitioner
Year: 2020

description: Vaccination of adult lactating dairy cattle can have a negative impact on milk production. Decreased milk production may occur from a combination of the cow’s immune response, endotoxin level in the vaccine, and the impact of cattle handling. A randomized clinical trial utilized 3 treatment groups to examine changes in milk production following vaccination with a Mannheimia haemolytica subunit vaccine (MHSV; Nuplura PH, Elanco Animal Health) using 972 lactating dairy cows on a single Midwestern dairy: a vaccinated group (MHSV, n=315); a placebo-treated control (saline, n=342); and a negative control group (no injections, n=315). The decline in milk across a 3 d post-treatment period for the saline group was 0.5 lb (0.2 kg) greater than the negative control cows, but the difference was not significant (P=0.57). The decline in milk during the same time period for cows in the MHSV group was 1.5 lb (0.7 kg) more than the negative control, (P=0.02). The declines between the saline group (0.5 lb; 0.2 kg) and the MHSV group (1.5 lb; 0.7 kg) were not significantly different (P=0.17).

description: This research aims at analysing thermo-chemical properties of the hypersonic high-enthalpy flow in the L2K wind tunnel, situated in Koln at the German Aerospace Center (DLR). ln the L2K wind tunnel, Martian atmosphere can be created, and the facility can simulate heat load conditions encountered during atmospheric entry of Martian missions. The focus of this project is the analysis of the non-intrusive experimental technique \"Tunable Diode Laser Absorption Spectroscopy\" (TDLAS), based on line of sight absorption spectroscopy, and applied to hypersonic flow. A simplified Martian atmosphere (97% CO2 and 3% N2) was used. A new interpretation for CO-TDLAS experimental technique applied to hypersonic wind tunnel flow analysis was developed. Numerical simulations with the DLR-TAU non-equilibrium flow solver were used as support of this analysis, and match between simulations and experiments was observed. Flow speed and absorption line\'s width were measured, and the knowledge of L2K\'s flow structure was extended.

Subjects: subject: Statistics Theory (math.ST)

description: We consider the problem of efficient estimation of the drift parameter of an Ornstein-Uhlenbeck type process driven by a Lévy process when high-frequency observations are given. The estimator is constructed from the time-continuous likelihood function that leads to an explicit maximum likelihood estimator and requires knowledge of the continuous martingale part. We use a thresholding technique to approximate the continuous part of the process. Under suitable conditions, we prove asymptotic normality and efficiency in the Hájek-Le Cam sense for the resulting drift estimator. Finally, we investigate the finite sample behavior of the method and compare our approach to least squares estimation.

description: The CALLISTO vehicle (for Cooperative Action Leading to Launcher Innovation in Stage TOss-back) is a flight demonstrator for future reusable launcher stages. The program involves three countries and their space organizations: CNES for France, DLR for Germany and JAXA for Japan. The first tests will be conducted from the CSG, Europe\'s Spaceport for commercial launches. The challenge is to develop, all along the project, the skills of the Partners. This knowhow includes Products and Vehicle design, Ground Segment set up, and post-flight operations for Vehicle recovery then reuse. It is a common and good practice to held a Flight Readiness Review at the latest before final operations clearing GO/NO GO for flight. Among the input for this review, a summary of all activities completed since the beginning of the program is provided: from initial product requirements compliance down to qualification testing period. In particular, this summary records all shortcomings that result in deviations to the launch system design-to-requirements, and especially the analysis proving that the residual risks of mission loss are acceptable. In the case of CALLISTO program, this basic approach is applied and tuned according to the top peculiarities of the project. Then and according to culture and background of three aerospace Agencies that may differ with each other, it was decided to implement and agree a tailor-made Flight Worthiness process and its resulting output: the Flight Worthiness Report [ 1 l Moreover, and for avoiding possible misunderstandings for such \"GO/NO GO for flight\" key event very late in the program, it was decided to conduct a kind of dry run of Flight Worthiness process much ahead of first flight itself: as soon as the System Critical Design Review (aka CDR-S). To do so, the upcoming CDR-S will include a status of the Flight Worthiness [I].

description: To examine the effects of transport stress and concur-rent respiratory infection on bovine vaccine responses, 75 previously weaned beef calves were randomly assigned to 1 of 3 treatments (n=25/group). Group 1 calves were not transported, but were vaccinated (NTV). Both Groups 2 (vaccinated TV) and 3 (not vaccinated TUV) were transported for 12 h. Twelve h after transport, calves in NTV and TV groups were vaccinated intranasally with modified-live bovine respiratory syncytial virus (BRSV), bovine herpesvirus −1 (BHV-1), and parainfluenza virus type 3 (PI3V), and subcutaneously with modified-live bovine viral diarrhea virus (BVDV) types 1 and 2 vaccine with Mannheimia hemolytica (Mh) leukotoxoid vaccine. Nasal secretions and serum were collected pre- and post-vaccination for measurement of nasal interferon alpha, beta, and gamma, IgA to BHV-1 and BRSV, and serum neutralizing (SN) titers to BHV-1, BRSV, and BVDV types 1 and 2. At vaccination some calves had nasal discharge and fever. Pre-vaccination nasal swabs, tested for respiratory viruses, were negative. During the 21-d study, 6 calves developed BRD and eventually recovered. BHV-1 and BVDV 1 and 2 SN titers were significantly higher in vaccinated than nonvaccinated calves on d 14 and 21. BVDV2 titers were significantly higher in TV than NTV. Vaccination stimulated systemic, but not mucosal, antibody responses. Cattle can mount a humoral response to vaccination in spite of transport and mild respiratory disease.

description: Anaplasma marginale is a gram-negative rickettsial pathogen that can cause clinical anemia and death in cattle. The objective of this study was to evaluate the effectiveness of enrofloxacin (ENR) 100 mg/mL at a single subcutaneous dose of 5.7 mg/lb (12.5 mg/kg) for treatment of acute anaplasmosis (ANA) in mature beef cows (n=67). Following intravenous inoculation with A. marginale-infected blood, cattle were monitored for clinical signs of ANA. Upon meeting case criteria, cattle were randomly assigned to receive ENR or saline (SAL). Treatment success, defined as 28 d post-treatment survival and resolution of abnormal clinical scores, was 81.8% (27/33) and 44.1% (15/34) (P=0.0032) for ENR and SAL treated cows, respectively. Mortality was 47% (16/34) and 3% (1/33) in SAL and ENR, respectively (P=0.0027). Packed cell volume at 7, 14, 21, and 28 d post-treatment was significantly greater in ENR compared to SAL (P<0.05). In this study, ENR improved treatment success compared to SAL, reduced ANA mortality, and maintained greater packed cell volumes post-clinical signs compared to SAL. Extra-label use of fluoroquinolones in food animals is prohibited in the United States, but ENR (Baytril® 100-CA1) was recently conditionally approved for treatment of ANA.

description: The single particle tunneling in a vertical stack consisting of monolayers of two-dimensional semiconductors is studied theoretically and its application to a novel Two-dimensional Heterojunction Interlayer Tunneling Field Effect Transistor (Thin-TFET) is proposed and described. The tunneling current is calculated by using a formalism based on the Bardeen's transfer Hamiltonian, and including a semi-classical treatment of scattering and energy broadening effects. The misalignment between the two 2D materials is also studied and found to influence the magnitude of the tunneling current, but have a modest impact on its gate voltage dependence. Our simulation results suggest that the Thin-TFETs can achieve very steep subthreshold swing, whose lower limit is ultimately set by the band tails in the energy gaps of the 2D materials produced by energy broadening. The Thin-TFET is thus very promising as a low voltage, low energy solid state electronic switch.
Explaining earnings variation of bovine veterinarians in private practice

Year: 2020

description: Bovine veterinarians are needed to protect food animal protein supplies, prevent losses due to disease, and protect public health: society needs these services. It is also important that economic incentives exist for, and are understood by, practitioners that serve the food animal industry. Surveys of American Association of Bovine Practitioners members were examined to explain variation in bovine veterinary earnings in private practice. We estimate the systematic variation in earnings due to practitioner characteristics. Results communicate expected earnings levels and variation across bovine veterinarians in private practice based on observable individual attributes and characteristics. These results communicate, in context of the survey questions, what the market for bovine veterinary services values. Bovine veterinarians are compensated more for specializing in a species within the food animal industries and owning their practice. The volume of animals seen is important, and bovine veterinarians should look to practice in areas with large concentrations of animals. Numbers of clients attained are not important, whereas numbers of animals serviced are. Further, gaining experience is more important than additional education or certifications beyond the doctor of veterinary medicine degree. However, there remains a large unexplainable variation in earnings models. This unexplained variation is likely due to unobserved and unmeasured ability/effort effects within each individual and it is thought, but not tested, that higher quality veterinarians earn more. Future salary surveys need to attempt to measure these deep human capital attributes.

description: Dermatophytosis is an important zoonotic superficial mycosis of cattle, primarily caused by the dermatophyte Trichophyton verrucosum. T. verrucosum presents a signifi-cant public health risk in the United States. The presence of dermatophyte lesions does not necessarily preclude issuance of certificates of veterinary inspection, and are permitted in some livestock shows and exhibition cattle if the inspecting veterinarian observes hair regrowth within the lesion. The objective of this study was to evaluate dermatophyte lesions, both without hair (alopecic or active) and with hair regrowth (resolving), for presence of T. verrucosum spores in calves. Our hypothesis was that the regrowth of hair would not correlate with the absence of infective material. Of the 34 calves sampled, 23 of 34 of the haired/resolving lesions had spores present, while 14/34 of the alopecic/active lesions had spores present. The odds of a haired/resolving sample having spores present was found to be 4 times that of the odds of an alopecic/active sample having spores present (p-value = 0.03516, 95% CI: 1.07, 22.09). Resolving lesions, as evidenced by regrowth of hair, did not correlate with mycologic cure in this study as spores were still recovered in many lesions designated as haired/resolving.

description: Recently, multi-screen cloud social TV is invented to transform TV into social experience. People watching the same content on social TV may come from different locations, while freely interact with each other through text, image, audio and video. This crucial virtual living-room experience adds social aspects into existing performance metrics. In this paper, we parse social TV user experience into three elements (i.e., inter-user delay, video quality of experience (QoE), and resource efficiency), and provide a joint analytical framework to enhance user experience. Specifically, we propose a cloud-based optimal playback rate allocation scheme to maximize the overall QoE while upper bounding inter-user delay. Experiment results show that our algorithm achieves near-optimal tradeoff between inter-user delay and video quality, and demonstrates resilient performance even under very fast wireless channel fading.

description: A 240-d study was conducted to assess the efficacy of long-acting, erodible implants containing Norgestomet (NOR; 11β-methyl-17α-acetoxy-19-norprogesterone) on growth performance and preventing pregnancy in grazing postpubertal beef heifers. Nonpregnant, cyclic crossbred beef heifers (n = 240) were stratified by BW (763 ± 7.5 lb [346 ± 3.40 kg]) and assigned to 80 blocks (3 heifers/block). Blocks were allocated randomly to 5 pastures (48 heifers/pasture). Heifers were assigned randomly within block to receive 1 of 3 implants (randomized complete block design) containing 0 (control), 100, or 150 mg NOR (d 0). Heifers grazed mixed fescue-bermudagrass pastures with ad libitum access to mineral-vitamin mix. Heifers were exposed to fertile bulls from d 7 to 200 (≥ 1 bull/25 heifers). Bull breeding soundness evaluations were conducted on d 0, 50, 100, and 150. Heifer BW was recorded pretreatment and on d 50, 100, 150, 200, and 240. Pregnancy was diagnosed by ultrasonography on d 50, 100, 150, 200, and 240. Orthogonal contrasts were used to assess the effects of control vs NOR (100 or 150 mg NOR) and dose efficacy (100 vs 150 mg NOR). Control heifers exhibited lower (P < 0.05) average daily gain (ADG) when compared to heifers that received 100 or 150 mg NOR (0.84 vs 1.04 and 1.06 lb [0.38 vs 0.47 and 0.48 kg]/d, respectively). Implants did not completely eliminate pregnancy at any NOR dosage. Pregnancy rates were 90.0 (90% CI = [82.9, 94.4]), 8.9 (90% CI = [4.8, 15.8]), and 12.5% (90% CI = [7.5, 20.0]) for control, 100, or 150 mg NOR, respectively. Heifers that received 100 or 150 mg NOR experienced lower (P < 0.0001) pregnancy rates compared to control heifers. By d 150, 88.8% (71/80) of control heifers were pregnant, and 90.0% (72/80) were pregnant by d 200. Administration of 100 or 150 mg NOR prevented pregnancy in at least 92.5% of heifers for 200 d. Pregnancy rates of heifers that received 100 or 150 mg NOR were not different (P = 0.46). These data suggest that implants containing 100 or 150 mg NOR increased rate of gain and decreased pregnancy rates in grazing postpubertal beef heifers.

description: In a uniformly rotating fluid, inertial waves propagate along rays that are inclined to the rotation axis by an angle that depends on the wave frequency. In closed domains, multiple reflections from the boundaries may cause inertial waves to focus on to particular structures known as wave attractors. Such structures have previously been studied from a theoretical point of view, in laboratory experiments, in linear numerical calculations and in some recent numerical simulations. In the present paper, two-dimensional direct numerical simulations of an inertial wave attractor are presented. In the linear regime, we first recover the results of the linear calculations and asymptotic theory of Ogilvie (2005) who considered a prototypical problem involving the focusing of linear internal waves into a narrow beam centred on a wave attractor in a steady state. The velocity profile of the beam and its scalings with the Ekman number, as well as the asymptotic value of the dissipation rate, are found to be in agreement with the linear theory. We also find that, as the beam builds up around the wave attractor, the power input by the applied force reaches its limiting value more rapidly than the dissipation rate, which saturates only when the beam has reached its final thickness. In the nonlinear regime, the beam is strongly affected and becomes unstable to a subharmonic instability. This instability transfers energy to secondary waves possessing shorter wavelengths and lower frequencies. The onset of the instability of a narrow inertial wave beam is investigated by means of a separate linear analysis and the results, such as the onset of the instability, are found to be consistent with the global simulations of the wave attractor. The excitation of such secondary waves described theoretically in this work has also been seen in recent laboratory experiments on internal gravity waves.

description: Digital disorders in cattle constitute the majority of lameness issues that bovine practitioners will encounter. Treatment of many digital infections in cattle can be facilitated in part by regional limb perfusions of either local anesthetics, antibiotics, or both. This article reviews infectious causes of digital disease, relevant clinical anatomy, use of various perfusates and tourniquet types in regional intravenous perfusions in cattle, and potential complications associated with the procedure.

description: The primary objective of this study was to evaluate the association between serum metabolic parameters and the risk of bovine respiratory disease (BRD) in high-risk beef stocker calves. Jugular venous blood samples were collected from mixed-breed beef bull, steer, and heifer calves (n=468) at the time of arrival processing at a stocker facility in northeast Georgia. Serum samples were then submitted for determination of serum creatinine, total calcium, phosphorus, magnesium, albumin, serum urea nitrogen, glucose, cholesterol, beta-hydroxybutyrate (BHBA), non-esterified fatty acid (NEFA), sodium, potassium, and chloride concentrations, as well as sodium:potassium ratio and NEFA:cholesterol ratio. Calves were monitored for the development of signs consistent with BRD for 45 days following arrival. A multi-variable logistic regression model was created to evaluate the association between serum variables and subsequent risk of BRD. In this analysis, BRD was associated with higher serum potassium, lower serum urea nitrogen, and lower BHBA concentrations at arrival processing. The area under the receiver operating characteristic curve for the ability of the model to predict morbidity was 0.645. These data suggest that hydration status, nutrient balance, and degree of rumen development may play a role in the development of BRD in high-risk beef stocker calves.

description: Tycho's supernova remnant (SNR) is well-established as a source of particle acceleration to very high energies. Constraints from numerous studies indicate that the observed gamma-ray emission results primarily from hadronic processes, providing direct evidence of highly relativistic ions that have been accelerated by the SNR. Here we present an investigation of the dynamical and spectral evolution of Tycho's SNR by carrying out hydrodynamical simulations that include diffusive shock acceleration of particles in the amplified magnetic field at the forward shock of the SNR. Our simulations provide a consistent view of the shock positions, the nonthermal emission, the thermal X-ray emission from the forward shock, and the brightness profiles of the radio and X-ray emission. We compare these with the observed properties of Tycho to determine the density of the ambient material, the particle acceleration efficiency and maximum energy, the accelerated electron to-proton ratio, and the properties of the shocked gas downstream of the expanding SNR shell. We find that evolution of a typical Type Ia supernova in a low ambient density (n_0 ~ 0.3 cm^{-3}), with an upstream magnetic field of ~5\ microGauss, and with ~16% of the SNR kinetic energy being converted into relativistic electrons and ions through diffusive shock acceleration, reproduces the observed properties of Tycho. Under such a scenario, the bulk of observed gamma-ray emission at high energies is produced by pi^0-decay resulting from the collisions of energetic hadrons, while inverse-Compton emission is significant at lower energies, comprising roughly half of the flux between 1 and 10 GeV.

description: Thirty-five Holstein cows were utilized in a completely randomized design to evaluate the efficacy of 2 doses of an aluminosilicate clay at reducing aflatoxin M1 (AFM1) transfer into milk. Cows were stratified by parity, stage of lactation, and milk production. Cows were assigned to 1 of 5 dietary treatments for 13 days (n = 7): (1) control (CON), basal diet; (2) clay control (4C), CON plus 4 oz clay; (3) aflatoxin (AF) control (AF-CON), CON plus 113 ppb AF; (4) AF-CON diet with 4 oz clay (4C+AF); or (5) AF-CON diet with 8 oz clay (8C+AF). Data were analyzed using the GLM procedure of SAS, and significance was declared when P ≤ 0.05. Milk yield was greatest in 4C+AF and 8C+AF cows and least in CON. Milk AFM1concentration averaged < 0.01, N/D (< 0.04 ppb), 1.64, 1.26, and 0.90 ppb for CON, 4C, AF-CON, 4C+AF, and 8C+AF diets, respectively. A dose response was observed for AFM1 transfer with a 21.88 and 40.63% reduction in cows consuming 4C+AF and 8C+AF diets, respectively. Feeding aluminosilicate clay to AF challenged Holstein cows resulted in a dose response reduction in AFM1 secretion and improved milk production.

Superconducting proximity effect and zero-bias anomaly in transport through quantum dots weakly attached to ferromagnetic leads

description: The Andreev transport through a quantum dot coupled to two external ferromagnetic leads and one superconducting lead is studied theoretically by means of the real-time diagrammatic technique in the sequential and cotunneling regimes. We show that the tunnel magnetoresistance (TMR) of the Andreev current displays a nontrivial dependence on the bias voltage and the level detuning, and can be described by analytical formulas in the zero temperature limit. The cotunneling processes lead to a strong modification of the TMR, which is most visible in the Coulomb blockade regime. We find a zero-bias anomaly of the Andreev differential conductance in the parallel configuration, which is associated with a nonequilibrium spin accumulation in the dot triggered by Andreev processes.

description: Over the years, supersymmetric quantum mechanics has evolved from a toy model of high energy physics to a field of its own. Although various examples of supersymmetric quantum mechanics have been found, systems that have a natural realization are scarce. Here, we show that the extension of the conventional Cooper-pair box by a 4pi-periodic Majorana-Josephson coupling realizes supersymmetry for certain values of the ratio between the conventional Josephson and the Majorana- Josephson coupling strength. The supersymmetry we find is a "hidden" minimally bosonized supersymmetry that provides a non-trivial generalization of the supersymmetry of the free particle and relies crucially on the presence of an anomalous Josephson junction in the system. We show that the resulting degeneracy of the energy levels can be probed directly in a tunneling experiment and discuss the various transport signatures. An observation of the predicted level degeneracy would provide clear evidence for the presence of the anomalous Josephson coupling.

description: Cylinder block/valve plate interface is one of the msot critical friction pairs in electro-hydrostatic actuator (EHA) pump, which greatly influences its performance and service life. In this paper, a new hard-on-hard material match is applied with CrN and DLC coated on the surface of W9Mo3 Cr4V cylinder block and valve plate, respectively. The friction-wear experiments are carried out on a specially designed test bench which could simulate the real working conditions. The results are compared with a traditional soft-on-hard material match of CuSnlO cylinder block and nitride 38CrMoAlA valve plate. The results indicate that adopting CrN and DLC coating can realize a much lower friction coefficient when the rotary speed is high, with the reduction percentage up to 30.41 % at 10 000 r/min. The wear of the CrN and DLC coating is basically consistent with soft-on-hard match, which the relatively soft part has higher wear depth. The match of hard-on-hard materials can be considered as a promising way to improve tribological characteristics of friction interfaces in EHA pumps. Keywords: electro-hydrostatic actuator pumps, cylinder block/valve plate interface, boundary lubrication/mixed friction, hard surface coating, friction and wear.

description: Liquid rocket engine regenerative thrust chambers are a critical component of launch vehicles. Since the material behavior with respect to the temperature drives the stress-strain plastic behavior of the aforementioned hardware, it is of primary importance to select an adequate compromise between thermal conductivity and mechanical properties. In the present study an innovative metal matrix composite, processed by LPBF additive manufacturing, is proposed. Nowadays, the so called dog house cycling failure mechanism of thrust chambers is still under investigation by the scientific community since it is driven by multiple material behaviors: low cycle fatigue, creep end local plastic instability. The present work aims to present the high temperature low cycle fatigue and creep properties investigated by an experimental activity performed on the new copper-maraging steel alloy.

description: We discuss a role of diproton correlation in two-proton emission from the ground state of a proton-rich nucleus, $^6$Be. Assuming the three-body structure of $α+ p + p$ configuration, we develop a time-dependent approach, in which the two-proton emission is described as a time-evolution of a three-body metastable state. With this method, the dynamics of the two-proton emission can be intuitively discussed by monitoring the time-dependence of the two-particle density distribution. With a model Hamiltonian which well reproduces the experimental two-proton decay width, we show that a strongly correlated diproton emission is a dominant process in the early stage of the two-proton emission. When the diproton correlation is absent, the sequential two-proton emission competes with the diproton emission, and the decay width is underestimated. These results suggest that the two-proton emission decays provide a good opportunity to probe the diproton correlation in proton-rich nuclei beyond the proton drip-line.
