Physical health in severe mental illness [PDF]

British Journal of General Practice, 2017
The indivisible self has become divided. Divided by the structures of medical specialism, which themselves reflect the understanding of a wider society. Divided too by a mind and body philosophy that prefers reductionism to holism. More recently, divided by healthcare management struggling to address the issues of integrated care for patients who place

Regularization of linear ill-posed problems involving multiplication operators [PDF]

arXiv, 2019
We study regularization of ill-posed equations involving multiplication operators when the multiplier function is positive almost everywhere and zero is an accumulation point of the range of this function. Such equations naturally arise from equations based on non-compact self-adjoint operators in Hilbert space, after applying unitary transformations ...

Persistent fatigue following SARS-CoV-2 infection is common and independent of severity of initial infection

medRxiv, 2020
Fatigue is a common symptom in those presenting with symptomatic COVID-19 infection. However, it is unknown if COVID-19 results in persistent fatigue in those recovered from acute infection.

Passive smoking, as measured by hair nicotine, and severity of acute lower respiratory illnesses among children

Tobacco Induced Diseases, 2002
The aim of this study was to describe the association between passive smoking and the severity of acute lower respiratory illnesses (ALRI) among 351 children aged 3-27 months admitted to hospital. A total of 297 children provided hair samples, which were

Methods of Solving Ill-Posed Problems [PDF]

arXiv, 2012
Many physical problems can be formulated as operator equations of the form Au = f. If these operator equations are ill-posed, we then resort to finding the approximate solutions numerically. Ill-posed problems can be found in the fields of mathematical analysis, mathematical physics, geophysics, medicine, tomography, technology and ecology.

Severity of illness and the teaching hospital

Academic Medicine, 1986
In the current environment of cost containment pressures on health care providers, teaching hospitals are facing increased financial risks that could jeopardize their special role in the health care delivery system. One of these risks is that the Medicare prospective payment system does not adequately account for severity of illness.

Baseline symptom severity and efficacy of Silexan in patients with anxiety disorders: A symptom-based, patient-level analysis of randomized, placebo-controlled trials

European Psychiatry
The influence of baseline severity on the efficacy of Silexan, a proprietary essential oil from Lavandula angustifolia, in anxiety disorders has not been investigated in a pooled dataset.

Some Results on the Regularization of LSQR for Large-Scale Discrete Ill-Posed Problems [PDF]

Science China Mathematics, 60 (4) (2017): 701-718, 2015
LSQR, a Lanczos bidiagonalization based Krylov subspace iterative method, and its mathematically equivalent CGLS applied to normal equations system, are commonly used for large-scale discrete ill-posed problems. It is well known that LSQR and CGLS have regularizing effects, where the number of iterations plays the role of the regularization parameter ...

Generalizing the SVD of a matrix under non-standard inner product and its applications to linear ill-posed problems [PDF]

arXiv, 2023
The singular value decomposition (SVD) of a matrix is a powerful tool for many matrix computation problems. In this paper, we consider generalizing the standard SVD to analyze and compute the regularized solution of linear ill-posed problems that arise from discretizing the first kind Fredholm integral equations. For the commonly used quadrature method
