The presence of heterogeneity is a significant attribute within the context of ovarian cancer. This study aimed to assess the predictive accuracy of models utilizing quantitative 18F-FDG PET/CT derived inter-tumor heterogeneity metrics in determining progression-free survival (PFS) and overall survival (OS) in patients diagnosed with high-grade serous ovarian cancer (HGSOC).

Orthodontic archwire materials are changing rapidly in our time. Because an ideal archwire material has not yet been found, assessment of the most effectual properties of different archwires including working range and its effect on root resorption is still an unmet clinical need. Unfortunately, most clinical studies lack standardization of subjects and force.

There is a tendency of an increasing number of signals and derived variables to be incorporated in the monitoring of patients during anesthesia and in intensive care units. The addition of new signals hardly ever leads to thedeletion of other signals. This is probably based on a feeling of insecurity. We must realize that each new signal that is being monitored brings along its cost, in terms of risk to the patient, investment and time.

The bureaucracy is the fourth branch of government, often receiving attention in times of emergency or when it is the object of criticism from the media or politicians. Less understood is how bureaucratic institutions function in a democracy, both from an organizational perspective and as institutional participants within the political arena. Drawing on rational choice approaches, computationally intensive data and modeling techniques, and systematic empirical inquiry, this original collection of essays highlights the important role bureaucracies play in shaping public policy-making.

In ebook "Biohybrid systems: Nerves, interfaces, and machines" the discipline of neurodesign is a highly interdisciplinary one, while at the same time in the process of maturing towards real-life applications. The breakthrough about to be achieved is to close the loop in communication between neural systems and electronic and mechatronic systems and actually let the nervous system adapt to the feedback from the man-made systems. To master this loop, scientists need a sound understanding of neurology, from the cellular to the systems scale, of man-made systems and how to connect the two.

The dynamic model is developed based on the conceptual model represented by a causal loop diagram (CLD). Next, CLD is converted into a stock and flow diagram (SFD), so the dynamic model can be simulated to achieve the proposed of this article. The result of simulation shows the decrease of service time variables can cause either decrease, increase or no change to the total, the event number, and the average of the reliability, average reliability, and maintainability of service and all services, as well as its demand.

Ebook "Introduction to computational biology: An evolutionary approach" Analysis of molecular sequence data is the main subject of this introduction to computational biology. There are two closely connected aspects to biological sequences: (i) their relative position in the space of all other sequences, and (ii) their movement through this sequence space in evolutionary time. Accordingly, the first part of the book deals with classical methods of sequence analysis: pairwise alignment, exact string matching, multiple alignment, and hidden Markov models.

Ebook "Photochemistry: A modern theoretical perspective" offers an introduction to photochemistry for students with a minimal background in physical chemistry and molecular quantum mechanics. The focus is from a theoretical perspective and highlights excited state dynamics. The authors, experienced lecturers, describe the main concepts in photochemical and photophysical processes that are used as a basis to interpret classical steady-state experimental results (essentially product branching ratios and quantum yields) and the most advanced time-resolved techniques.

This thesis develops a flexible customer behavior analysis system, including essential head pose estimation or F-formation modules. This system will be evaluated in an actual retail store. Further, after studying the system, realizing the mentioned problems of the head pose problem, we also propose a process to collect the head pose dataset and multi-task deep neural network model, fusing face detection and head pose estimation to yield face position and head pose at the same time.
