Article Abstract
According to the second law of thermodynamics, for every transformation performed on a system which is in contact with an environment of fixed temperature, the average extracted work is bounded by the decrease of the free energy of the system. However, in a single realization of a generic process, the extracted work is subject to statistical fluctuations which may allow for probabilistic violations of the previous bound. We are interested in enhancing this effect, i.e. we look for thermodynamic processes that maximize the probability of extracting work above a given arbitrary threshold. For any process obeying the Jarzynski identity, we determine an upper bound for the work extraction probability that depends also on the minimum amount of work that we are willing to extract in case of failure, or on the average work we wish to extract from the system. Then we show that this bound can be saturated within the thermodynamic formalism of quantum discrete processes composed by sequences of unitary quenches and complete thermalizations. We explicitly determine the optimal protocol which is given by two quasi-static isothermal transformations separated by a finite unitary quench.
Background: Worldwide, tuberculosis (TB) is among the most common causes of death. To our knowledge, there has been no study showing the prevalence of EPTB in Khuzestan province. Therefore, the objective of this research was to investigate the prevalence of EPTB in patients with or without pulmonary TB in different cities of Khuzestan province from 2002 to 2023.
Background: Most transgender people face different conditions of health vulnerability on a daily basis. In the Brazilian context, no research review has been found on such situations in the light of the theoretical conceptualization of multidimensional vulnerability. This research aimed to identify and analyze components of social and/or programmatic vulnerability that interfere with access to health care for trans people in Brazil.

Objective: Evolving digital technology has paved the way for endless potentiality. Leveraging on digital technology for healthcare purposes can target cancer patients, thus improving physical and psychological symptoms. Nevertheless, there is limited consolidated evidence on the effectiveness of virtual reality (VR) and mobile applications.

Emerging evidence suggests that lipid-laden macrophages (LLM) participate in lung damage in various clinical conditions. However, the mechanisms involved in LLM formation are not fully understood. In this study, we aimed to investigate the link between reactive oxygen species (ROS) and LLM formation.
Accurately monitoring the content of Cu and Hg in real samples and biological systems is of great significance in ensuring food safety and human health. Therefore, developing efficient methods for simultaneously detecting Cu and Hg is of great significance in living organisms and real samples. In this work, a bifunctional ratiometric and colorimetric fluorescent bio-sensor DPT-1, was designed and synthesized using triphenylamine to specifically and concurrently detect Cu and Hg exhibited varying degrees of fluorescence quenching through "turn-off" fluorescence.
