Optical parametric chirped-pulse amplification (OPCPA) operation with low gain by seeding with high-energy, clean pulses is shown to significantly improve the contrast to better than 10(-10) to 10(-11) in a high-intensity Ti:sapphire laser system that is based on chirped-pulse amplification. In addition to the high-contrast broadband, high-energy output from the final amplifier is achieved with a flat-topped spatial profile of filling factor near 77%. This is the result of pump beam spatial profile ...

Protein kinases are known for their highly conserved adenosine triphosphate (ATP)-binding site, rendering the discovery of selective inhibitors a major challenge. In theory, allosteric inhibitors can achieve high selectivity by targeting less conserved regions of the kinases, often with an added benefit of retaining efficacy under high physiological ATP concentration. Although often overlooked in favor of ATP-site directed approaches, performing a screen at high ATP concentration or stringent hit ...

Background: Reports have shown that visceral adipose tissue (VAT) is more closely linked to cardiovascular risk factors (CRFs) than subcutaneous adipose tissue (SAT). We aimed to elucidate preferential abdominal fat loss and the correlations between abdominal fat reductions and changes in CRFs achieved with a moderate low-carbohydrate diet (LCD) in patients with type 2 diabetes (T2DM). Patients and methods: Fifty-two outpatients (28 men and 24 women, mean age ± SD: 60.0 ± 10.5 years) with hemoglobin A 1c ( ...

We investigated the effect of a 3-month M-LCD on visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT), and examined an association between decrease in carbohydrate intake and reduction in abdominal fat among patients with Type 2 diabetes mellitus (T2DM).Seventy-six patients (45 men and 31 women; mean age ± SD: 59.5 ± 11.1 years) with T2DM were ...

To determine whether good glycemic control can be achieved with a 30%-carbohydrate diet in severe type 2 diabetes, 33 outpatients (15 males, 18 females, mean age: 59 yrs) with HbA1c levels of 9.0% or above were instructed to follow a low-carbohydrate diet (1852 ...

A search for sequential charged leptons decaying into massive neutrinos has been performed at ${E}_{\mathrm{c}.\mathrm{m}.}=56$ GeV at the KEK colliding-beam accelerator TRISTAN. We have found no evidence for the production of the charged heavy leptons for an integrated luminosity of 5.3 ${\mathrm{pb}}^{\ensuremath{-}1}$. A search for stable charged leptons was also conducted yielding null results. A new mass limit on the charged heavy leptons was obtained as a function of the mass of the associated ...

No evidence has been found for the production of the top quark. From the study using the event shape of the multihadron events, the upper limit of the production cross section is found to be 16 pb at thcc 95% confidence level.

The obseved angular distributions are consistent with QCD, but are inconsistent with the Abelian gluon model at the 5% significance level. We have further obtained 95%-confidence experimental bounds on the fundamental parameters of the SU(${\mathit{N}}_{\mathit{c}}$) local color symmetry.

A charge asymmetry has been measured in hadron jets from e+e− annihilation at energies between 52 and 61.4 geV (〈√s〉=57.6 GeV). The measured asymmetry is A=11.4%±2.2%±2.1% and is consistent with the prediction of the standard model of the electroweak theory. By using the differential cross section, lower limits of the compositeness scale in eeqq contact interactions have been determined to be typically a few TeV at 95% CL.

The electron bunch has high stability and high reproducibility compared with single pulse electron generation. In the case of 180° collision, special measures have been taken to prevent damage. In the case of 135° ...

The differential cross sections for e + e - → e + e - and e + e - →γγ have been measured at the highest energy of \(\sqrt{s}=52\) GeV in e + e - collisions.The process e + e - → e + e - is well understood within the framework of the standard model of electroweak interactions. The reaction e + e - →γγ is found to be in good agreement with QED. The 95% confidence limits obtained for the QED cut-off parameters are \(\varLambda_{+}>61\) GeV and \(\varLambda_{-}>72\) GeV for e + e - →γγ.

A search for a new charge -(1/3 quark has been carried out at the KEK ${e}^{+}$${e}^{\mathrm{\ensuremath{-}}}$Collider TRISTAN under the assumption of its photonic decay through a flavor-changing neutral current (FCNC). The observed number of multihadronic events with isolated photons is consistent with that expected from the known five quark flavors. Including the usual charged-current decays, limits on the absolute photonic branching ratio and FCNC processes were obtained.

Although postprandial glucose levels largely depend on carbohydrate intake, the impact of carbohydrate and its sources on hemoglobin A1c (HbA1c) levels has not been demonstrated in patients with type 2 diabetes (T2DM) probably because, in previous studies, more than 50% of patients were taking anti-diabetic medication, and the researchers used energy percent of carbohydrate as an indicator of carbohydrate intake.We recruited 125 Japanese men (mean age 58±12 years) and 104 women (mean age 62±10 years) ...

We report the demonstrated irradiation effect of laser-accelerated protons on human cancer cells. In vitro (living) A549 cells are irradiated with quasimonoenergetic proton bunches of 0.8–2.4 MeV with a single bunch duration of 15 ns. Irradiation with the proton dose of 20 Gy results in a distinct formation of γ-H2AX foci as an indicator of DNA double-strand breaks generated in the cancer cells. This is a pioneering result that points to future investigations of the radiobiological effects of laser- ...
