Structure of Λ10^{10}_{\Lambda}Be and Λ10^{10}_{\Lambda}B hypernuclei studied with the four-body cluster model

The structure of the isodoublet hypernuclei, $^{10}_{\Lambda}$B and $^{10}_{\Lambda}$Be within the framework of an $\alpha +\alpha +\Lambda +N$ four-body cluster model is studied. Interactions between the constituent subunits are determined so as to reproduce reasonably well the observed low-energy properties of the $\alpha \alpha$, $\alpha N$, $\alpha \Lambda$, $\alpha \alpha \Lambda$ and $\alpha \alpha N$ subsystems. Furthermore, the two-body $\Lambda N$ interaction is adjusted so as to reproduce the $0^+$-$1^+$ splitting of $^4_{\Lambda}$H. The $\Lambda$ binding energies of $^{10}_{\Lambda}$B and $^{10}_{\Lambda}$Be are 8.76 MeV and 8.94 MeV, respectively. The energy splitting of the $1^-$-$2^-$ levels in $^{10}_{\Lambda}$B is 0.08 MeV, which does not contradict the experimental report in BNL-E930. An even-state $\Lambda N$ charge symmetry breaking (CSB) interaction determined from the A=4 systems works repulsively by +0.1 MeV (attractively by -0.1 MeV) in $^{10}_{\Lambda}$Be ($^{10}_{\Lambda}$B). We discuss a possibility that an odd-state CSB interaction improves the fitting to the experimental data of A=10 double $\Lambda$ hypernuclei.Comment: 20 pages and 7 fugures, To be published in Progress of Theoretical Physic

Superdeformed Λ\Lambda hypernuclei with antisymmetrized molecular dynamics

The response to the addition of a $\Lambda$ hyperon is investigated for the deformed states such as superdeformation in $^{41}_\Lambda$Ca, $^{46}_\Lambda$Sc and $^{48}_\Lambda$Sc. In the present study, we use the antisymmetrized molecular dynamics (AMD) model. It is pointed out that many kinds of deformed bands appear in $^{45}$Sc and $^{47}$Sc. Especially, it is found that there exists superdeformed states in $^{45}$Sc. By the addition of a $\Lambda$ particle to $^{40}$Ca, $^{45}$Sc and $^{47}$Sc, it is predicted, for the first time, that the superdeformed states exist in the hypernuclei $^{41}_\Lambda$Ca and $^{46}_\Lambda$Sc. The manifestation of the dependence of the $\Lambda$-separation energy on nuclear deformation such as spherical, normal deformation and superdeformation is shown in the energy spectra of $^{41}_\Lambda$Ca, $^{46}_\Lambda$Sc and $^{48}_\Lambda$Sc hypernuclei.Comment: 24 pages, 8 figure

Effectiveness of outpatient-based group cognitive-behavioral therapy in Japanese patients with mood disorders and neurotic disorders

Background: Although the effectiveness of group cognitive-behavioral therapy (GCBT) has been studied, evidence is still not sufficient. Objective: The aim of the present study is to consider the effectiveness of GCBT with mood disorders and neurotic disorders. Methods: The present study assessed a total of 32 patients who were classified as F3 (mood disorders) or F4 (neurotic disorders) according to the ICD-10, and who attended GCBT sessions offered at The Tokai University Hospital. Depression and mood in these patients were assessed before and after GCBT by using the Center for Epidemiologic Studies Depression Scale (CES-D) and the Profile of Mood States (POMS). Results: A comparison of pre- and post-GCBT CES-D scores among all patients as well as within F3 and F4 groups showed a significant decrease in CES-D scores after GCBT. As for the POMS, a comparison of pre- and post-GCBT scores among all patients showed a significant improvement in “vigor” and “confusion” scores after GCBT. Discussion: The present study demonstrated that GCBT can relieve depression and improve some mood states. Furthermore, the GCBT sessions offered proved to be effective even when administered to a group of participants consisting of both mood disorders and neurotic disorder patients

Electrical muscle stimulation on upper and lower limb muscles in critically ill patients

Objectives: Electrical muscle stimulation (EMS) is widely used to enhance lower limb mobilization. Although upper limb muscle atrophy is common in critically ill patients, EMS application for the upper limbs has been rarely reported. The purpose of this study was to investigate whether EMS prevents upper and lower limb muscle atrophy and improves physical function. Design: Randomized controlled trial. Setting: Two-center, mixed medical/surgical intensive care unit (ICU). Patients: Adult patients who were expected to be mechanically ventilated for >48 h and stay in the ICU for >5 days. Interventions: Forty-two patients were randomly assigned to the EMS (n = 17) or control group (n = 19). Measurements and Main Results: Primary outcomes were change in muscle thickness and cross-sectional area of the biceps brachii and rectus femoris from day 1 to 5. Secondary outcomes included incidence of ICU-acquired weakness (ICU-AW), ICU mobility scale (IMS), length of hospitalization, and amino acid levels. The change in biceps brachii muscle thickness was −1.9% vs. −11.2% in the EMS and control (p = 0.007) groups, and the change in cross-sectional area was −2.7% vs. −10.0% (p = 0.03). The change in rectus femoris muscle thickness was −0.9% vs. −14.7% (p = 0.003) and cross-sectional area was −1.7% vs. −10.4% (p = 0.04). No significant difference was found in ICU-AW (13% vs. 40%; p = 0.20) and IMS (3 vs. 2; p = 0.42) between the groups. The length of hospitalization was shorter in the EMS group (23 [19–34] vs. 40 [26–64] days) (p = 0.04). On day 3, the change in the branched-chain amino acid level was lower in the EMS group (40.5% vs. 71.5%; p = 0.04). Conclusion: In critically ill patients, EMS prevented upper and lower limb muscle atrophy and attenuated proteolysis and decreased the length of hospitalization

An asymptotic analysis for an integrable variant of the Lotka-Volterra prey-predator model via a determinant expansion technique

Abstract: The Hankel determinant appears in representations of solutions to several integrable systems. An asymptotic expansion of the Hankel determinant thus plays a key role in the investigation of asymptotic analysis of such integrable systems. This paper presents an asymptotic expansion formula of a certain Casorati determinant as an extension of the Hankel case. This Casorati determinant is then shown to be associated with the solution to the discrete hungry Lotka-Volterra (dhLV) system, which is an integrable variant of the famous prey-predator model in mathematical biology. Finally, the asymptotic behavior of the dhLV system is clarified using the expansion formula for the Casorati determinant
