Article Synopsis
  • * This experiment produced 2.05 MJ of laser energy, resulting in 3.1 MJ of total fusion yield, which exceeds the Lawson criterion for ignition, demonstrating a key milestone in fusion research.
  • * The report details the advancements in target design, laser technology, and experimental methods that contributed to this historic achievement, validating over five decades of research in laboratory fusion.

During May 2016, a corky textured, "star like" symptom, located at the apex on the far side of the fruit was observed on young persimmon fruitlets (Fig. 1), on several persimmon varieties in plantations located along the Mediterranean Sea coast. The lesions caused cosmetic damage, which disqualified the fruit from marketing and can affect as much as 50% of the fruit in the orchard.

Article Synopsis
  • * In inertially confined fusion, ignition allows the fusion process to spread into surrounding fuel, potentially leading to higher energy output.
  • * Recent experiments at the National Ignition Facility achieved capsule gains of 5.8 and approached ignition, even though "scientific breakeven" has not yet been fully realized.

Technologies and practices that reduce the environmental impacts of US agriculture are well documented. Less is known about how best to encourage their adoption. We report on the results of a large randomized controlled trial conducted with nearly 10,000 agricultural producers in the United States.

Millimeter-sized CD foils fielded close (order mm) to inertial confinement fusion (ICF) implosions have been proposed as a game-changer for improving energy resolution and allowing time-resolution in neutron spectrum measurements using the magnetic recoil technique. This paper presents results from initial experiments testing this concept for direct drive ICF at the OMEGA Laser Facility. While the foils are shown to produce reasonable signals, inferred spectral broadening is seen to be high (∼5 keV) and signal levels are low (by ∼20%) compared to expectation.

We present narrow-band self-emission x-ray images from a titanium tracer layer placed at the fuel-shell interface in 60-laser-beam implosion experiments at the OMEGA facility. The images are acquired during deceleration with inferred convergences of ∼9-14. Novel here is that a systematically observed asymmetry of the emission is linked, using full sphere 3D implosion modeling, to performance-limiting low mode asymmetry of the drive.

Background: Six hundred and four surviving children aged 2 years, who had been entered into a neonatal trial of fresh frozen plasma on the incidence of intraventricular haemorrhage, were grouped into four categories of disability based on a review by a full paediatric assessment. A 29 item questionnaire completed by the children's health visitors was used to group the children into the same categories.

Aims: To explore whether severe disability could be identified by using only a few of the 29 questions.

The outcome at age 2 years of preterm babies recruited into a three-arm randomised controlled trial of prophylactic volume expansion was ascertained in two ways: from a neurodevelopmental assessment performed by a paediatrician and from responses on a brief questionnaire completed by the child's personal health visitor. Of 776 babies recruited into the trial, 604 survived to the age of 2 years and the findings of a paediatric assessment were available for all survivors. Questionnaires were sent to the health visitors of 601 of the survivors; 513 (85.

Aims: To evaluate a parental questionnaire as a means of providing outcome measures for a multicentre randomised controlled trial of treatment for post-haemorrhagic ventricular dilatation.

Methods: The parents of 88 survivors were sent a questionnaire before a paediatric assessment at the age of 30 months. The parents' responses to individual questions taken mainly from the Griffiths' mental development scales and their perception of the child's ability to see and hear were compared with the paediatric findings.

Portal hypertension with varices developed in 18/675 patients with chronic myeloid leukaemia (CML) in a randomized trial comparing busulphan with busulphan and thioguanine. All 18 had received the drug combination and none busulphan alone (P less than 0.0001).

The MRC has conducted randomised trials in CLL sine 1978: CLL 1 (1978-84), 660 patients; CLL 2 (1984-90), 640 patients; CLL 3 (from June 1990), 90 patients. Centralised morphological diagnosis and membrane marker studies have allowed the exclusion of non-CLL disorders. Some of the treatment questions were repeated in more than one trial.

We report the analysis of prognostic factors in a cohort of 660 patients entered in the first Medical Research Council trial in chronic lymphocytic leukaemia (CLL) between 1978 and 1984. The majority (94%) of patients were aged 50 or over and the number of men (M) was almost twice that of women (F) with an M:F ratio of 1.8:1.

The Medical Research Council (MRC) Working Party on Leukaemia in Adults has conducted two randomised trials in CLL since 1978. CLL 1 ran from 1978 to 1984 and recruited 660 eligible patients. The number of males was twice the number of females and the distribution of cases by stage was different in the sexes: 58% of females were stage A, 25% stage B and 17% stage C; in males the proportions for stages A, B and C were 40%, 30% and 30% respectively.
