Historically, systems analysis and design methodologies have been used as a guide in software development. Such methods provide structure to software engineers in their efforts to create quality solutions in the real world of information systems. This article looks at the elements that constitute a systems analysis methodology and examines the historical development of systems analysis in software development. It concludes with observations on the strengths and weaknesses of four methodologies and the state of the art of practice today.

The amorphous/crystalline (A/C) assembly in molecular solids has a direct bearing on their attributes and applications, including mechanical, pharmaceutical, electronic and photophysical. A systematic analysis of the molecular features and interactions that determine the predilection towards the A, C or bi-stable A-C states is critical. This fundamental problem is addressed through an exhaustive investigation of a large family of alkoxyalkyl diaminodicyanoquinodimethanes (ROR'-DADQs); enhancement of their fluorescence from the solution, to the A, to the C state serves as an excellent signature of the phase preference and temporal stability.

Therapeutic hurdles persist in the fight against lung cancer, although it is a leading cause of cancer-related deaths worldwide. Results are still not up to par, even with the best efforts of conventional medicine, thus new avenues of investigation are required. Examining how immunotherapy, precision medicine, and AI are being used to manage lung cancer, this review shows how these tools can change the game for patients and increase their chances of survival.

The burden of cardiovascular disease has declined in high-income countries in the past 3 decades but is growing in low- and middle-income countries due to epidemiological, demographic, and socioeconomic shifts. A range of cost-effective policies and interventions are available for advancing cardiovascular health (CVH) through primordial, primary, and secondary prevention. We showcase multifaceted challenges that stifle the global progress of CVH including shortcomings in financial protection, health systems, primary health care, national health policies, service coverage, and surveillance.

Accurate annotation of these residual potentials by three-dimensional electroanatomical mapping systems is challenging and can be misleading. Herein, we present a case of successful LAPW isolation using peak frequency analysis.
