REVIEW
Ioannis Sgouralis, Steve Pressé
The hidden Markov model (HMM) has been a workhorse of single-molecule data analysis and is now commonly used as a stand-alone tool in time series analysis or in conjunction with other analysis methods such as tracking. Here, we provide a conceptual introduction to an important generalization of the HMM, which is poised to have a deep impact across the field of biophysics: the infinite HMM (iHMM). As a modeling tool, iHMMs can analyze sequential data without a priori setting a specific number of states as required for the traditional (finite) HMM...

In the competency-based medical education (CBME) approach, clinical competency committees are responsible for making decisions about trainees' competence. However, we currently lack a theoretical model for group decision-making to inform this emerging assessment phenomenon. This paper proposes an organizing framework to study and guide the decision-making processes of clinical competency committees.This is an explanatory, non-exhaustive review, tailored to identify relevant theoretical and evidence-based papers related to small group decision-making...

PURPOSE: To evaluate the treatment outcomes with high-dose-rate (HDR) interstitial brachytherapy (HDR-BRT) in head and neck cancers (HNC). MATERIAL AND METHODS: Fifty-eight patients with HNC as per American Joint Committee on Cancer (AJCC) TNM staging criteria were analyzed retrospectively between 2008 and 2015. Forty-two patients received external beam radiotherapy (EBRT) with HDR-BRT and 16 patients received BRT alone. The survival was calculated with respect to median biological equivalent doses (BED) and median 2 Gy equivalent dose (EQD2), keeping α/β = 10 for tumor...

Excellent chemical and physical properties of glass, over a range of operating conditions, make it a preferred material for chemical detection systems in analytical chemistry, biology, and the environmental sciences. However, it is often compromised with SU8, PDMS, or Parylene materials due to the sophisticated mask preparation requirements for wet etching of glass. Here, we report our efforts toward developing a photolithography-free laser-patterned hydrofluoric acid-resistant chromium-polyimide tape mask for rapid prototyping of microfluidic systems in glass...

The last few years have seen the advancement of high-throughput experimental techniques produce an extraordinary amount of data. Bioinformatics and statistical analyses have become instrumental to interpreting the information coming from e.g. sequencing data, and often motivate further targeted experiments. The broad discipline of "computational biology" spans far beyond the well-established field of bioinformatics, but it is our impression that more theoretical methods like mathematical models are not yet as well integrated in the research studying microbial interactions...

BACKGROUND: Understanding factors surrounding the implementation process of mass drug administration for lymphatic filariasis (MDA for LF) elimination programmes is critical for successful implementation of similar interventions. The sub-Saharan Africa (SSA) region records the second highest prevalence of the disease and subsequently several countries have initiated and implemented MDA for LF. Systematic reviews have largely focused on factors that affect coverage and compliance, with less attention on the implementation of MDA for LF activities...

Evaluation must attend meaningfully and respectfully to issues of culture, race, diversity, power, and equity. This attention is especially critical within the evaluation of science, technology, engineering, and mathematics (STEM) educational programming, which has an explicit agenda of broadening participation. The purpose of this article is to report lessons learned from the implementation of a values-engaged, educative (Greene et al., 2006) evaluation within a multi-year STEM education program setting. This meta-evaluation employed a case study design using data from evaluator weekly systematic reflections, review of evaluation and program artifacts, stakeholder interviews, and peer review and assessment...

INTRODUCTION: The transition from paediatric to adult care poses risks to the health of young adults living with HIV if unsuccessful, including interruptions in care and poor health outcomes. Evolving best practices in HIV healthcare transition should ideally be informed by real-world qualitative and quantitative clinical healthcare transition outcomes. There has been a recent proliferation of HIV healthcare transition outcome research, largely from Europe and North America. METHODS: A literature search was undertaken using the online databases PubMed, Web of Science, and Google Scholar...

BACKGROUND: Efforts to improve HIV diagnosis and antiretroviral therapy (ART) initiation among people living with HIV and reduce onward transmission of HIV rely on innovative interventions along multiple steps of the HIV care continuum. These innovative methods are particularly important for key populations, including men who have sex with men (MSM) and transgender women (TW). The HIV epidemic in Myanmar is concentrated among key populations, and national efforts now focus on reducing stigma and improving engagement of MSM and TW in HIV prevention and care...

BACKGROUND: Ventilator-associated pneumonia (VAP) is defined as the occurrence of pneumonia in patients receiving mechanical ventilation for more than 48 h after endotracheal intubation. The implementation of effective oral care with antiseptics may reduce the incidence of ventilator-associated pneumonia. However, previous studies have been unclear about the best antiseptic for this purpose. Therefore, present protocol proposed to perform a network meta-analysis to evaluate the efficacy of different antiseptics to prevent ventilator-associated pneumonia...

We review research findings and the limitations of recent qualitative and quantitative studies of HIV prevalence and risk behaviors in military populations in three Caribbean countries (Dominican Republic, Belize, and Barbados). This research shows how mental health issues, disordered substance use, and structuring aspects of the occupational field produce and reproduce patterns of risk behaviors. We discuss the use of formative research, the Positive Health, Dignity, and Prevention framework, and the use of implementation science (including research methods that employ alternative methodological assumptions to better elucidate both cultural nuances and unknown components of program impact in different military populations) as a means to tailor individual prevention strategies to military populations...

The creative process is fun, complex, and sometimes frustrating, but it is critical to the future of our nation and progress in science, technology, engineering, mathematics, as well as other fields. Thus, we set out to see if implementing methods of active learning typical to the theatre department could impact the creativity of senior capstone design students in the Bioengineering department. Senior Bioengineering capstone design students were allowed to self-select into groups. Prior to the beginning of coursework, all students completed a validated survey measuring engineering design self-efficacy...

Departing from the conventional view of the reasons for the behavior of living systems, this research presents a radical and unique view of that behavior, as the observed side effects of a hierarchical set of simple, continuous, and dynamic negative feedback control systems, by way of an experimental model implemented on a real-world autonomous robotic rover. Rather than generating specific output from input, the systems control their perceptual inputs by varying output. The variables controlled do not exist in the environment, but are entirely internal perceptions constructed as a result of the layout and connections of the neural architecture...
