Proposed New Framework Scheme for Path Loss in Wireless Body Area Network

Recent technical developments in wi-fi networking, microelectronic integration and programming, sensors and the Internet have enabled us to create and enforce a range of new framework schemes to fulfil the necessities of healthcare-related wireless body area network (WBAN). WBAN sensors continually screen and measure patients’ indispensable signs and symptoms, and relay them to scientific monitoring for diagnosis. WBAN has a range of applications, the most necessary of which is to help patients suffering diseases to stay alive. The quality instance is the coronary heart implant sensor, whose video display unit monitors coronary heart sign and continuously transmits it. This setup eliminates the need for patients to visit the medical doctor frequently. Instead, they can take a seat at home and acquire an analysis and prescription for the disease. Today, a sizable effort is being made to increase low-power sensors and gadgets for utility in WBAN. A new framework scheme that addresses route loss in WBAN and discusses its penalties in depth is endorsed in this paper. The new framework scheme is applied to three case scenarios to obtain parameters by measuring vital information about the human body. On-body and intrabody conversation simulations are conducted. On-body conversation findings show that the route loss between transmitter and receiver rises with growing distance and frequency

Reasoning about “reasoning about reasoning”: semantics and contextual equivalence for probabilistic programs with nested queries and recursion

Metareasoning can be achieved in probabilistic programming languages (PPLs) using agent models that recursively nest inference queries inside inference queries. However, the semantics of this powerful, reflection-like language feature has defied an operational treatment, much less reasoning principles for contextual equivalence. We give formal semantics to a core PPL with continuous distributions, scoring, general recursion, and nested queries. Unlike prior work, the presence of nested queries and general recursion makes it impossible to stratify the definition of a sampling-based operational semantics and that of a measure-theoretic semantics—the two semantics must be defined mutually recursively. A key yet challenging property we establish is that probabilistic programs have well-defined meanings: limits exist for the step-indexed measures they induce. Beyond a semantics, we offer relational reasoning principles for probabilistic programs making nested queries. We construct a step-indexed, biorthogonal logical-relations model. A soundness theorem establishes that logical relatedness implies contextual equivalence. We demonstrate the usefulness of the reasoning principles by proving novel equivalences of practical relevance—in particular, game-playing and decisionmaking agents. We mechanize our technical developments leading to the soundness proof using the Coq proof assistant. Nested queries are an important yet theoretically underdeveloped linguistic feature in PPLs; we are first to give them semantics in the presence of general recursion and to provide them with sound reasoning principles for contextual equivalence.

The study incorporates a thematic analysis approach, and the data is collected from primary sources by conducting semi-structured interviews with four experts working in IT organizations. This research would be useful for recruiters and HR managers to consider the fields of AI implementation and management to take advantage of cost-cutting technical developments.

STRENGTHENING SPATIAL PERSPECTIVE THROUGH GIS APPLICATIONS IN TRANSPORT MODELING

The process of transporting passengers and goods takes place in space; therefore, geospatial foundations are considered in transport models. Considering conceptual, methodological and technical developments in this direction, the relevance of an integrated approach becomes obvi-ous. The article deals with geographic information systems and their application in modeling transport processes. Three areas are identified in which the spatial perspective contributes to effective modeling and increasing the reliability of the results obtained. The purpose of the study is to prove the prospects of spatial transport modeling with the integration of geographic information systems

Advances in lung cancer diagnosis and treatment - a review

Lung cancer is the second and third most common cancer in Iceland for females and males, respectively. Although the incidence is declining, lung cancer still has the highest mortality of all cancers in Iceland. Symptoms of lung cancer can be specific and localized to the lungs, but more commonly they are unspecific and result in significant diagnostic delay. Therefore, majority of lung cancer patients are diagnosed with non-localized disease. In recent years, major developments have been made in the diagnosis and treatment of lung cancer. Positive emission scanning (PET) and both transbroncial (EBUS) or transesophageal ultrasound (EUS) biopsy techniques have resulted in improved mediastinal staging of the disease and minimal invasive video-assisted thoracic surgery (VATS) has lowered postoperative complications and shortened hospital stay. Technical developments in radiotherapy have benefitted those patients who are not candidates for curative surgery. Finally, and most importantly, recent advances in targeted chemotherapeutics and development of immunomodulating agents have made individual tailoring of treatment possible. Recent screening-trials with low-dose computed tomography show promising results in lowering mortality. This evidence-based review focuses on the most important developments in the diagnosis and treatment of lung cancer, and includes Icelandic studies in the field.

Recent Advances in the Understanding of Specific Efferent Pathways Emerging From the Cerebellum

The cerebellum has a long history in terms of research on its network structures and motor functions, yet our understanding of them has further advanced in recent years owing to technical developments, such as viral tracers, optogenetic and chemogenetic manipulation, and single cell gene expression analyses. Specifically, it is now widely accepted that the cerebellum is also involved in non-motor functions, such as cognitive and psychological functions, mainly from studies that have clarified neuronal pathways from the cerebellum to other brain regions that are relevant to these functions. The techniques to manipulate specific neuronal pathways were effectively utilized to demonstrate the involvement of the cerebellum and its pathways in specific brain functions, without altering motor activity. In particular, the cerebellar efferent pathways that have recently gained attention are not only monosynaptic connections to other brain regions, including the periaqueductal gray and ventral tegmental area, but also polysynaptic connections to other brain regions, including the non-primary motor cortex and hippocampus. Besides these efferent pathways associated with non-motor functions, recent studies using sophisticated experimental techniques further characterized the historically studied efferent pathways that are primarily associated with motor functions. Nevertheless, to our knowledge, there are no articles that comprehensively describe various cerebellar efferent pathways, although there are many interesting review articles focusing on specific functions or pathways. Here, we summarize the recent findings on neuronal networks projecting from the cerebellum to several brain regions. We also introduce various techniques that have enabled us to advance our understanding of the cerebellar efferent pathways, and further discuss possible directions for future research regarding these efferent pathways and their functions.
