Employed but Unpaid, Volunteers or Paradoxical Surplus? Sierra Leone's Unsalaried Health Workforce
The International Journal of Health Planning and Management, EarlyView.ABSTRACT Background In 2016, 36.5% of Sierra Leone's health workforce consisted of unsalaried clinical staff whose payroll inclusion was deferred. The Ministry of Health introduced policies to reduce this percentage, renewing pledges to introduce health workforce planning.

Alternative Price Dynamics and Valuation of Flexible Strategies
International Journal of Finance &Economics, EarlyView.ABSTRACT In this article, we study the optimal operational strategy of production projects. We investigate different underlying price models and determine the optimal barriers of transition to suspension, recovery, or irreversible abandonment of productive activity.

A Discontinuous Sturm-Liouville Operator With Indefinite Weight
Journal of Mathematics Research, 2010 In this paper, we consider an indefinite Sturm-Liouville operator with eigenparameter-dependent boundary conditions andtransmission conditions. In an appropriate space K, we define a new self-adjoint operator A such that the eigenvalues ofA coincide with those of such a problem and obtain asymptotic approximation for its eigenvalues and eigenfunctions.

Market Expansion and Business Stealing With Differentiated Products Using a Nested Logit
Journal of Applied Econometrics, EarlyView.ABSTRACT In this paper, we use the widely adopted nested logit model to examine how introducing a new product into a market of highly substitutable, differentiated goods affects both market expansion and business stealing. Central to our analysis is the nesting parameter σ$$ \sigma $$, which captures the correlation in consumers' unobserved utilities ...

Frontiers in the Management of Orthopaedic Periprosthetic Joint Infection
Journal of Orthopaedic Research, EarlyView.ABSTRACT Periprosthetic joint infection (PJI) is a devastating complication of total joint arthroplasty (TJA), one of the most frequently performed surgical procedures worldwide. Management of acute PJI commonly involves debridement, antibiotics, and implant retention (DAIR), though failure rates remain high due to antibiotic‐tolerant biofilms. Chronic

Some remarks on an eigenvalue problem for an anisotropic elliptic equation with indefinite weight
Filomat, 2019 In this paper, we consider an eigenvalue problem for an anisotropic elliptic equation with indefinite weight, in which the differential operator involves partial derivatives with different variable exponents.

Photonic Systolic Array for All‐Optical Matrix–Matrix Multiplication
Laser &Photonics Reviews, EarlyView.A photonic systolic array is introduced, offering extreme parallelism in matrix‐matrix multiplication based on the synchronized movement of optical pulses along a crossbar array. Optical pulses traveling in perpendicular directions meet at freeform‐designed multiply‐accumulate units, each tailored to generate two signals whose intensity difference ...

Brane Realizations of Quantum Hall Solitons and Kac-Moody Lie Algebras [PDF]
, 2010 Using quiver gauge theories in (1+2)-dimensions, we give brane realizations of a class of Quantum Hall Solitons (QHS) embedded in Type IIA superstring on the ALE spaces with exotic singularities.

A Low‐Cost and Compact High‐Frequency Gallium Nitride Gradient Power Amplifier for Low‐Field MRI
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To reduce the upfront cost of small, low‐field MRI systems, while expanding the capabilities of their gradient systems. Methods A gradient power amplifier was designed to leverage the lowering cost of Gallium Nitride (GaN) power transistors and high speed logic, to achieve high efficiency and responsiveness for driving gradient coils ...
