Four-dimensional lattice results on the MSSM electroweak phase transition

We present the results of our large scale 4-dimensional (4d) lattice simulations for the MSSM electroweak phase transition (EWPT). We carried out infinite volume and continuum limit extrapolations and found a transition whose strength agrees well with perturbation theory. We determined the properties of the bubble wall that are important for a successful baryogenesis.Comment: 5 pages, 3figures.

Electroweak Phase Transition in the MSSM: 4-Dimensional Lattice Simulations

Recent lattice results have shown that there is no Standard Model (SM) electroweak phase transition (EWPT) for Higgs boson masses above \approx 72 GeV, which is below the present experimental limit. According to perturbation theory and 3-dimensional (3d) lattice simulations there could be an EWPT in the Minimal Supersymmetric Standard Model (MSSM) that is strong enough for baryogenesis up to m_h \approx 105 GeV. In this letter we present the results of our large scale 4-dimensional (4d) lattice simulations for the MSSM EWPT. We carried out infinite volume and continuum limits and found a transition whose strength agrees well with perturbation theory, allowing MSSM electroweak baryogenesis at least up to m_h = 103 \pm 4 GeV. We determined the properties of the bubble wall that are important for a successful baryogenesis.Comment: 4 pages, 4 figures included; lightest Higgs mass bound relaxed (abstract, fig. 3 changed), version to appear in Phys.

Contour deformation trick in hybrid NLIE

The hybrid NLIE of AdS_5 x S^5 is applied to a wider class of states. We find that the Konishi state of the orbifold AdS_5 x (S^5/Z_S) satisfies A_1 NLIE with the source terms which are derived from contour deformation trick. For general states, we construct a deformed contour with which the contour deformation trick yields the correct source terms.Comment: 39 pages, 6 figures, v2: discussion on analyticity constraints replaced by consistent deformed contou

Hypothyroidism and type d personality:Results from E-MPATHY, a cross-sectional international online patient survey

ContextBetween 10% and 15% of people with hypothyroidism experience persistent symptoms, despite achieving biochemical euthyroidism.The underlying causes are unclear. Type D personality (a vulnerability factor for general psychological distress) is associated with poor healthstatus and symptom burden but has not been studied in people with hypothyroidism.ObjectiveTo investigate type D personality in hypothyroidism and explore associations with other characteristics and patient-reported outcomes.DesignMultinational, cross-sectional survey.SettingOnline.ParticipantsIndividuals with self-reported, treated hypothyroidism.InterventionQuestionnaire.Main Outcome MeasuresType D personality and associations with baseline characteristics, control of the symptoms of hypothyroidism bymedication, satisfaction with care and treatment of hypothyroidism, impact of hypothyroidism on everyday living.ResultsA total of 3915 responses were received, 3523 of which were valid. The prevalence of type D personality was 54.2%. Statisticallysignificant associations were found between type D personality and several respondent characteristics (age, marital status, ethnicity,household income, comorbidities, type of treatment for hypothyroidism, most recent TSH level), anxiety, depression, somatization, poorcontrol of the symptoms of hypothyroidism by medication, dissatisfaction with care and treatment of hypothyroidism, and a negative impactof hypothyroidism on everyday living).DiscussionOur study found a high prevalence of type D personality among people with hypothyroidism who responded to the survey. Type Dpersonality may be an important determinant of dissatisfaction with treatment and care among people with hypothyroidism. Our findings requireindependent confirmation. Close collaboration between the disciplines of thyroidology and psychology is likely to be key in progressing ourunderstanding in this area

Nonlinear integral equations for finite volume excited state energies of the O(3) and O(4) nonlinear sigma-models

We propose nonlinear integral equations for the finite volume one-particle energies in the O(3) and O(4) nonlinear sigma-models. The equations are written in terms of a finite number of components and are therefore easier to solve numerically than the infinite component excited state TBA equations proposed earlier. Results of numerical calculations based on the nonlinear integral equations and the excited state TBA equations agree within numerical precision.Comment: numerical results adde

On the Discrete Logarithmic Minkowski Problem

A new sufficient condition for the existence of a solution for the logarithmic Minkowski problem is established. This new condition contains the one established by Zhu [70] and the discrete case established by Böröczky et al. [7] as two important special cases. © The Author(s) 2015.

Use of thyroid hormones in hypothyroid and euthyroid patients: A survey of members of the Endocrine Society of Australia

\ua9 2024 The Authors. Clinical Endocrinology published by John Wiley & Sons Ltd.Objective: Hypothyroidism is a common endocrine condition usually managed with levothyroxine (LT4). However, controversy remains around the use of liothyronine (LT3). We aimed to investigate the practices of Australian endocrinologists when managing patients with hypothyroidism, their use of LT3 + LT4 combination therapy and use of thyroid hormones in euthyroid patients. Design and Participants: Members of the Endocrine Society of Australia (ESA) were invited to participate in an online questionnaire. Measurements: We analysed questionnaires that had complete demographic data. Results: Eighty-seven questionnaires fulfilled the criteria. LT4 was used as first line treatment for hypothyroidism by all respondents. Only 45% reported that their patients were dispensed the brand of LT4 that they recommend. LT3 (alone or in combination) was prescribed by 44% in their clinical practice. Although 49% of respondents would consider LT3 + LT4 in patients with normal TSH who had ongoing symptoms of hypothyroidism, the inability of LT4 to restore normal physiology was ranked the least likely explanation for persistent symptoms and only 32% would consider it for themselves if they were diagnosed with hypothyroidism. The majority (55%), in accordance with evidence, would not prescribe thyroid hormone to euthyroid individuals but 39% would consider use in euthyroid female infertility with high levels of thyroid antibodies and 11% in euthyroid patients with a simple goitre growing over time. LT4 use in pregnancy was variable among members. Conclusions: Australian endocrinologists mostly follow international guidelines when prescribing thyroid hormone therapy and many prescribe combination LT3 and LT4 therapy, particularly for patients who remain symptomatic on LT4 monotherapy. Prescribing practices are largely similar to other countries who have completed similar questionnaires

Konishi operator at intermediate coupling

TBA equations for two-particle states from the sl(2) sector proposed by Arutyunov, Suzuki and the author are solved numerically for the Konishi operator descendent up to 't Hooft's coupling lambda ~ 2046. The data obtained is used to analyze the properties of Y-functions and address the issue of the existence of the critical values of the coupling. In addition we find a new integral representation for the BES dressing phase which substantially reduces the computational time.Comment: lots of figures, v2: improved numerics, c1=2, c2=0, c4 does not vanis
