Exergy of passive states: Waste energy after ergotropy extraction.

Work extraction protocol is always a significant issue in the context of quantum batteries, in which the notion of ergotropy is used to quantify a particular amount of energy that can be extracted through unitary processes. Given the total amount of energy stored in a quantum system, quantifying wasted energy after the ergotropy extraction is a question to be considered when undesired coupling with thermal reservoirs is taken into account. In this paper, we show that some amount of energy can be lost when we extract ergotropy from a quantum system and quantified by the exergy of passive states.

Lost clips after targeted lymph node biopsy in breast cancer patients: Follow-up of the CLIP-study.

Introduction: Clipping and selective removal of axillary lymph nodes in breast cancer patients presenting with initially node-positive disease and achieving a nodal downstaging after primary systemic therapy is a less invasive method for axillary staging. An imaging guided localization and successful extirpation of these clipped lymph nodes is not possible in all patients. To date no follow-up data regarding patients with lost clips are available.

Entanglement, coherence, and charging process of quantum batteries.

Quantum devices are systems that can explore quantum phenomena, such as entanglement or coherence, for example, to provide some enhancement performance concerning their classical counterparts. In particular, quantum batteries are devices that use entanglement as the main element in their high performance in powerful charging. In this paper, we explore quantum battery performance and its relationship with the amount of entanglement that arises during the charging process.

Long-Term Effects of Repeated Cycles of Intrathecal Triamcinolone Acetonide on Spasticity in MS Patients.

Main Problem: Spasticity is a common feature in patients with multiple sclerosis (MS). Although options have broadened over the last years, there are still patients with no response to common therapeutic agents. Intrathecal administered triamcinolone acetonide (TCA) has been tested for spasticity in patients with MS.

Effects of intrathecal triamincinolone-acetonide treatment in MS patients with therapy-resistant spasticity.

Objectives: Multiple sclerosis (MS) is an autoimmune disease affecting young people and is a major cause of disability. In the course of time, disability progresses and symptoms like spasticity may occur. Spasticity is a major cost factor in MS patients.
