Reheating Metastable O'Raifeartaigh Models [PDF]

, 2006
In theories with multiple vacua, reheating to a temperature greater than the height of a barrier can stimulate transitions from a desirable metastable vacuum to a lower energy state.

Finetuning foundation models for joint analysis optimization in High Energy Physics [PDF]

Machine Learning: Science and Technology
In this work we demonstrate that significant gains in performance and data efficiency can be achieved in High Energy Physics (HEP) by moving beyond the standard paradigm of sequential optimization or reconstruction and analysis components.

Development of a Grasshopper‐Leg‐Inspired Back‐Type Exoskeleton for the Reduction of Muscle Activation During Stoop Activities

Journal of Field Robotics, EarlyView.
ABSTRACT Farmers frequently suffer from musculoskeletal disorders, particularly lower back pain (LBP), mainly due to occupational ergonomic factors such as repetitive stooping and lifting. This study proposes using an exoskeleton to reduce LBP risk by providing external torque to the hip joints.

Bouncing Cosmologies: Progress and Problems

, 2016
We review the status of bouncing cosmologies as alternatives to cosmological inflation for providing a description of the very early universe, and a source for the cosmological perturbations which are observed today.

Proposal of a novel APPLE‐KNOT undulator by selecting the KNOT field as the dominant magnetic field

Journal of Synchrotron Radiation, EarlyView.
The degradation of circular polarization state in conventional APPLE‐KNOT undulators has been noted. To overcome this limitation, we propose a novel APPLE‐KNOT undulator design which utilizes the KNOT magnetic field as the dominant component.The APPLE‐KNOT undulator forms composite magnetic fields by superimposing an APPLE field and a KNOT field with ...

Black hole evaporation based upon a q-deformation description

, 2005
A toy model based upon the $q$-deformation description for studying the radiation spectrum of black hole is proposed. The starting point is to make an attempt to consider the spacetime noncommutativity in the vicinity of black hole horizon.

Targeting the noradrenergic‐metabolic axis: A new strategy for sugar‐induced depression subtypes

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Lifestyle is closely related to major depressive disorder (MDD). Given the growing focus on the impact of diet on mental health, this study examined how dietary habits affect the pathophysiology of MDD. Experimental Approach Health check‐up data were analysed. Mice received sucrose under chronic unpredictable mild stress

Noncommutative field gas driven inflation

, 2008
We investigate early time inflationary scenarios in an Universe filled with a dilute noncommutative bosonic gas at high temperature. A noncommutative bosonic gas is a gas composed of bosonic scalar field with noncommutative field space on a commutative ...

Ultrasound and MRI abdominal fat distribution and its associations with metabolic conditions in adults with abdominal obesity

Diabetes, Obesity and Metabolism, EarlyView.
Abstract Aims To evaluate the accuracy of abdominal fat distribution of subcutaneous (SAT) and visceral adipose tissue (VAT) assessed by ultrasound (US) compared to magnetic resonance imaging (MRI), as the gold standard technique. Additionally, to assess the association between abdominal fat distribution measured by US and metabolic conditions in ...
