  • Reparameterized multiobjective control of BCG immunotherapy

    Nonlinear bladder cancer model In this study, a bladder cancer model27,28 is employed, as depicted in Fig. 1. The model considers the impact of BCG vaccines on various populations, including uninfected tumor cells, infected tumor cells, and effector T cells. The administration of BCG vaccines to the tumor site converts uninfected tumor cells into infected tumor…

  • Development of a hybrid LSTM with chimp optimization algorithm for the pressure ventilator prediction

    Materials The ventilator data used in this work was obtained from the Google Brain public dataset, which is publicly accessible on Kaggle42. An artificial bellows test lung was attached to a custom open-source ventilator using a respiratory circuit to create the dataset. Figure 1 shows the configuration, with the predicted state variable (airway pressure) indicated in…

  • Study of noise and structural characteristics of twin-screw air compressor based on multi-physical field coupling

    The acoustic-structural coupling analysis of the air compressor shell was done by multi-physical field coupling technique. When the incident frequency is 1300 Hz, the air compressor shell characteristics, such as sound pressure level, deformation, and surface acceleration distribution are analyzed respectively. In order to obtain the distribution law of sound pressure level, deformation and surface acceleration…

  • Complete computer model of the ear simulates every aspect of hearing

    Complete computer model of the ear simulates every aspect of hearing

    Encompassing all features from the outer ear to the auditory nerve, a comprehensive computer model of the ear has been built that may be used to simulate hearing in mammals, including humans.  The human hearing system is a complex and intricate sensory mechanism that enables us to perceive and interpret sound. This system involves several…

  • Study warns that workaholism ruins mood and may even result in death

    Study warns that workaholism ruins mood and may even result in death

    Workaholism is a pattern of behavior in which an individual is overly committed to their work, frequently at the expense of other elements of their life such as health, relationships, and leisure activities. While a strong work ethic and dedication to one’s career are admirable qualities, workaholism is characterized by an excessive and compulsive concern…

  • Links found between ultra-processed foods and mouth and throat cancers

    Links found between ultra-processed foods and mouth and throat cancers

    According to a new study led by researchers from the University of Bristol and the International Agency for Research on Cancer (IARC), eating more ultra-processed foods (UPFs) may be associated with an increased risk of developing cancers of the mouth, throat, and esophagus. The research examined the nutrition and lifestyle habits of 450,111 adults who…

  • Scientists discover that your ears speak to your eyes and vice versa

    Scientists discover that your ears speak to your eyes and vice versa

    In 2018, Duke University researchers discovered that when the eyes move, the ears generate a tiny almost imperceptible murmur and the other way around. Now, following up on their first study, the scientists investigated if the faint audio impulses generated by the body parts contained comprehensive information about eye movements.  Estimating the eye position from…

  • Minefield Clearance: Military and Civilian Innovations

    Minefield Clearance: Military and Civilian Innovations

    In the realm of minefield clearance, the M1150 Assault Breacher Vehicle (ABV) takes center stage with its Mine Clearing Line Charge (MICLIC) system, a vital tool for military operations since 2009. This rope-like device, armed with 1,760 pounds of explosives, paves the way for troops to navigate safely through treacherous terrains. On the civilian front,…

  • Good news! Animals affected by global warming have options for relocation

    Good news! Animals affected by global warming have options for relocation

    Global warming has a substantial impact on animal habitat ranges. The distribution and characteristics of habitats change as the Earth’s climate evolves, influencing ecosystems and the organisms that inhabit them.  An increase in average temperatures is one of the most direct effects of global warming. This can modify the temperature ranges appropriate for various species.…
