An intuitive picture or mental image of reality from sense experience is apparently structured from orthogonal and independent sense inputs in association with past memories. Such images are not necessarily visual but may have such qualities. Play of mind with information in mental images processed by molecular actors is guided with rules of reality to assure non-contradictory outcome of actions for successful behaviors (Rogers and Jain 1993). Such functions have evolved to find food before becoming food, and fight or flight when in doubt. Shadows of ignorance that obscure mental images and associated states also have epistemic utility. Their success depends on learning from trials and errors to compensate for incomplete information and uncertainties with consideration of what could go wrong. Outcomes are also influenced by games played on mind by illusions, mistakes, surprises, ignorance. Loss of time, energy, and opportunity associated with ignored or misinterpreted information threaten survival. Equivocation, cynicism, wild goose chase, and vicious circle of sterile ideas encourage contradictory or inconsistent interpretations that compromise outcomes. Throughout the human history, ignorance of horsemen of apocalypse has unleashed havocs, perpetuated wars, epidemics, wrongful medical treatments, and economic disasters. What used to be crisis of ignorance has now become crisis of unintended consequences of inventions and other forms of knowledge. Ignorance of experts and head of states as horsemen of darkness brings misery to countless innocents. In Nay formalism, knowledge (gyan) is what knows with certainty (either as true or false). Identifying uncertainties introduces doubt (syad) in what one knows. For finding ones way around lack of relevant evidence (agyan), wisdom lies in recognition of ignorance and identifies problem to seek solution. Note that these states for propositions are not necessarily related by binary negations.展开更多

Excitingly we recognized the similarities between the cellular dynamics of the immune system and our lives, activities, and behaviors. Observing the immune system can guide how to respond to various daily situations, including when to react, tolerate, or ignore. Recognizing this analogy between our lives and the immune system should motivate us to adopt a wisdom-based approach when investigating the mechanisms and future discoveries related to this system and to deepen our understanding of this complex system with newfound respect. In this context, the present review examines several integral biological processes of the immune system by drawing parallels between them and human life, activities, and behaviors to learn how we must behave based on the insights offered by this complex organization. The literature search was conducted in international databases such as PubMed/MEDLINE and Google Scholar search engine using English equivalent keywords from 1998 up to April 2023. The search strategy used the following subject heading terms: Immune system, analogy, human life, cellular dynamics, memory, tolerance, and ignorance. In conclusion, the immune system is a complex organization comprising various cells interacting within specific sites and networks, communicating, drawing experiences, and learning how to tolerate certain conditions that make it share certain similarities with human life.展开更多

The method considers the influence of instantaneous wing deforming in flapping,as well as the induced drag,additionally models the stretching and the dissipation of vortex rings,and can present the aerodynamics status on the wing surface. An implementation of the method is developed. Moreover,the results and the efficiency of the proposed method are verified by CFD methods. Considering the less time cost of UVLM,for application of UVLM in the MAV optimization,the influence of wake vortex ignoring time saving and precision is studied. Results show that saving in CPU time with wake vortex ignoring the appropriate distance is considerable while the precision is not significantly reduced. It indicates the potential value of UVLM in the optimization of MAV design.展开更多

Acute pulmonary embolism is an extremely common and potentially the serious pattern of venous thromboembolic disease. Unfortunately, missed diagnosis of pulmonary embolism is lethal and common because of its non-specific symptoms and signs. Patient concerns: A 42-year-old male patient presented with acute chest pain that was treated as gastroesophageal reflux disease. Diagnosis: Suspected acute pulmonary embolism. Interventions: O2inhalation, urgent electrocardiography, and cardiopulmonary resuscitation. Outcomes: Deterioration and sudden cardiac death. Lessons: Physicians should pay much attention to the symptoms and signs of pulmonary embolism to reduce the rate of missed diagnosis.展开更多

Lessons learned from the 1918 flu pandemic, highlight the importance of wearing a face mask in conjunction with adherence to other public health recommendations. There are two key factors that influence how our communities are translating scientific evidence, <em>denialism and ignorance</em>. Sadly, a real consequence of this pandemic among a significant number of patients with COVID-19 disease is denial. As health care providers we need to take part in addressing these issues and educate our communities especially during this time where we see a second and larger uptake of COVID-19 cases. Fighting denialism and ignorance represents a significant challenge to our society and could have a substantial positive impact on helping with vaccine acceptability and other public health recommendations.展开更多

Both favor long, meandering sentences, in which they insert voluminous asides. In thematic terms, their narratives are constantly involved with meditation over the extent to which we can understand the past, or the degree to which we can know either ourselves or others. Beyond their common preoccupation with time and memory, I will consider some remarkable similarities between Marias' and Proust's formative years and the role translation played in the development of their style. I will show the many ways in which Proust "haunts" Marias: in his metaphorical use of the translating practice, in his love of deferral, and in his brooding first-person narrators, racked by the anxiety of ignorance.展开更多

A large decrease in the speed spread of the electron pulses(we called “boundary kick”) is observed and properly treated leading to a significant improvement in the simulation accuracy, particularly when the density of electrons is very large. We show that our method is consistent with the simulation by the N-particle method, while others can introduce factorial error.展开更多

Ignored curriculum not only in the design but also should be considered at the implementation level. The present study examined the experiences of teachers in general education from ignored curriculum in higher education and this study was done by qualitative research and its approach was interpretive phenomenology. In this regard, semi-structured interviews were conducted with twenty-six teachers of general education courses and the data obtained from these interviews were analyzed by using phenomenology of Smith. Three major themes from ignored curriculum, were found from the experience of teachers including 1) lack of attention to requirements which consists of three sub-categories: in attention to the needs of the learner, the needs and demands of everyday life and the needs of experts;2) lack of attention to content;3) run into problems involving the four sub-problems of teaching, evaluation time, space and assessment. The teachers during the training and implementing courses have gained a lot of experience from the ignored curriculum that had impact on their perception. Planners are familiar with academics experiences and identify ignored curriculum of general education courses and emphasized on how they understand the main goals of general education courses and made it meaningful and they had a main role in eliminating the flaws of this course, and enhance the effectiveness of them. In summary, the results obtained from the study were that general education courses, do not address the needs of learners. These requirements include of three sub-categories: inattention to the needs of the learner, routine needs and professionals. Also, courses have less attention to content. And there are problems such as difficulties in teaching this lesson, time, space and evaluation.展开更多
