Evaluation of The Effectiveness of a Direct Observed Therapy Program With Vietnamese Tuberculosis Patients

Tuberculosis (TB) has long been recognized as a major public health problem. The rate of TB is high in immigrants and the frequency of drug resistance is increasing. A major reason for the development of resistant infections as well as relapse is poor adherence to TB treatment. In response to this problem, direct observed therapy (DOT) was introduced to the TB program in Santa Clara County in 1993. The purpose of this study is to compare the completion rates, relapse rates, and sputum conversion rates between a DOT group and a non-DOT group of Vietnamese TB patients. A chart review was completed with a convenience sample of 25 records of DOT patients and 25 records of non-DOT patients. Frequencies and percentages were used to analyze the completion rates and the relapse rates. The results show that the completion of therapy rate was 16% higher in the DOT group and the relapse rate was 8% lower. A t-test indicated that the sputum conversion rate was significantly more rapid in the DOT group than in the non-DOT group (p \u3c.05). It appears that Vietnamese TB patients benefit from the DOT program

Lyapunov exponents as a dynamical indicator of a phase transition

We study analytically the behavior of the largest Lyapunov exponent $\lambda_1$ for a one-dimensional chain of coupled nonlinear oscillators, by combining the transfer integral method and a Riemannian geometry approach. We apply the results to a simple model, proposed for the DNA denaturation, which emphasizes a first order-like or second order phase transition depending on the ratio of two length scales: this is an excellent model to characterize $\lambda_1$ as a dynamical indicator close to a phase transition.Comment: 8 Pages, 3 Figure

Blockchain and other innovations in entrepreneurial finance: implications for future policy

More than a decade after the Global Financial Crisis (GFC) of 2007–08, entrepreneurial finance has exhibited enormous changes, notably in the rise of alternative nonbank financing. This has been most acutely experienced in the provision and delivery of early stage and innovative business finance—the focus of this special issue. The ensuing innovations in entrepreneurial finance have taken place in developed and developing economies, presenting considerable challenges to policymakers. This editorial paper reviews the special issue articles on this subject and their implications for future research, practice and policy

IoT Forensics: Challenges For The IoA Era

Challenges for IoT-based forensic investigations include the increasing amount of objects of forensic interest, relevance of identified and collected devices, blurry network boundaries, and edgeless networks. As we look ahead to a world of expanding ubiquitous computing, the challenge of forensic processes such as data acquisition (logical and physical) and extraction and analysis of data grows in this space. Containing an IoT breach is increasingly challenging – evidence is no longer restricted to a PC or mobile device, but can be found in vehicles, RFID cards, and smart devices. Through the combination of cloud-native forensics with client-side forensics (forensics for companion devices), we can study and develop the connection to support practical digital investigations and tackle emerging challenges in digital forensics. With the IoT bringing investigative complexity, this enhances challenges for the Internet of Anything (IoA) era. IoA brings anything and everything “online” in a connectedness that generates an explosion of connected devices, from fridges, cars and drones, to smart swarms, smart grids and intelligent buildings. Research to identify methods for performing IoT-based digital forensic analysis is essential. The long-term goal is the development of digital forensic standards that can be used as part of overall IoT and IoA security and aid IoT-based investigations
