Can we develop a device to prevent death in NICU babies?4 answersDeveloping a device to prevent death in NICU babies is possible. Incorporating human-centered design principles and utilizing methods such as simulation and clinical testing can improve the safety of devices used in caring for neonates. However, there are significant regulatory, financial, social, and ethical barriers to development that need to be overcome. In a non-randomized controlled trial, the BEMPU bracelet, a hypothermia monitoring device, was found to significantly reduce neonatal mortality. Regular bioethical education, activation of bioethical committees in NICU, and the establishment of a hospice unit for dying babies are suggested to lessen the burdens faced by doctors and parents. Ensuring that NICU babies receive their mother's milk is important for reducing morbidity and mortality. The waitlist mortality for heart transplants in neonates and infants remains high, but modifications to protocols and the use of different devices have shown improvements in survival rates.
How does a Noise become hazardous to people?5 answersExcessive noise can become hazardous to people in several ways. Firstly, it can cause temporary or permanent hearing loss if it is loud enough. Secondly, there is evidence to suggest that noise may contribute to the development of heart disease.

What are the pitch characteristics of children in speech recognition?
3 answersThe pitch characteristics of children in speech recognition have been studied in several papers. Children's speech is found to have high values of pitch, abnormal spectrum, and well-marked high-frequency. The pitch of children's speech is generally higher than that of adults. The increase in pitch of children's speech leads to an increase in the dynamic range and variances of higher order coefficients of Mel frequency cepstral coefficient (MFCC) features. To address the pitch differences between adults and children, various techniques have been proposed, such as spectral smoothening, pitch reduction, and pitch-based spectrum normalization. These techniques aim to improve the performance of automatic speech recognition (ASR) systems trained on adults' speech for recognizing children's speech.How does external noise affect someone's memory?
5 answersExternal noise can have an impact on someone's memory. Studies have shown that increasing external noise does not affect the precision with which visual information can be recalled from working memory. However, meaningful external noise at low sound pressure levels can cause annoyance and decrease performance in mental tasks, such as short-term memory tasks. Additionally, external noise can lead to a shift in memory strategies employed by individuals. In the presence of noise, individuals with an external locus of control tend to decrease their use of higher-level semantic memory strategies and increase their use of lower-level perceptual strategies. Therefore, external noise can have negative effects on memory recall and the strategies used for memory tasks.What is the weather outside?

3 answersBusiness incubators offer various courses to support the growth and development of small and medium enterprises (SMEs). These courses cover areas such as business development, management, technology support, and problem-solving skills. In addition, incubators provide training in individual and organizational knowledge, observable skills, and attitudes and beliefs that influence startup empowerment processes. Vocational high schools also use business incubators as a means of fostering student interest in entrepreneurship. The courses taught in these incubators include entrepreneurship theory, practical experience, skills development, and knowledge essential to starting new businesses. Corporate incubators, on the other hand, focus on fostering innovation activities beyond the company's current business. The specific courses offered by corporate incubators may vary depending on the company's objectives and industry.What is the definition of neuroscience?
5 answersNeuroscience is the scientific study of the nervous system, including the brain, spinal cord, and peripheral nervous system, as well as its functions. It is an interdisciplinary field that collaborates with other sciences such as chemistry, engineering, psychology, and medicine. The field has made significant advances in recent decades, thanks to progress in related fields like molecular biology, electrophysiology, and computational neuroscience. Neuroscience aims to understand various aspects of the brain, including its structure, development, function, and neurological disorders, and seeks ways to treat these abnormalities. It also investigates the biological basis of consciousness, perception, memory, and learning. Neuroscientists are constantly exploring the brain's activities and trying to unravel its mysteries, even when it appears to be inactive.What is the background of neuroscience?
5 answersThe background of neuroscience can be traced back to ancient times, with early civilizations attempting to understand the mysteries of the brain and its functions. Over the centuries, there have been significant developments in our understanding of nerve and brain function, including the recognition of the brain's control over sensation, movement, learning, and thought. The neuron doctrine, which states that the brain and spinal cord are made up of individual elements called neurons, was a fundamental principle in understanding the structure of the nervous system. Additionally, the discovery of chemical transmitter substances and the ionic basis of the action potential furthered our understanding of communication and electrical signaling in the nervous system. Observations of brain injuries and the development of techniques for single-cell recording and imaging revealed the specialization of different parts of the brain and spinal cord for specific functions. These historical developments laid the foundation for modern neuroscience.How does inaccurate travel demand modeling forecasts affect transportation policy development or policy performance?
5 answersInaccurate travel demand modeling forecasts can have significant implications for transportation policy development and policy performance. These forecasts, generated by AI-based models, may introduce prediction biases and fairness issues, potentially exacerbating social inequalities in decision-making processes. Limited studies have focused on addressing the fairness issues of these models, highlighting the need for fairness-aware travel demand forecasting methodologies. Additionally, research has shown that measured traffic is often lower than forecasted volumes, with a mean absolute deviation of 17% from the forecast. Factors such as road volume, functional class, time span, and the use of travel models can influence forecast accuracy. Furthermore, the presence of infrequently large prediction errors can impact the performance of demand-responsive public transport systems, highlighting the importance of accurate demand predictions for effective operation.How do ears locate sound?
3 answersEars locate sound through a combination of cues such as the relative time of arrival and sound level across the two ears, frequency-dependent filtering by the head and ears, and the shape and size of the head and outer ear (pinna). In mammals, the middle ear evolved as a chain of three ossicles, enabling sound transmission up to higher frequencies. Lizards, on the other hand, have extreme directionality in their ears, created by strong acoustical coupling of the eardrums, which allows for simple neural processing of sound direction. The pinnae, or outer ears, also play a significant role in sound localization, as they have a distinguished shape in each person and can determine the front or back location of the sound source. Internally coupled ears, where eardrum vibrations are coupled through an air-filled interaural cavity, also contribute to sound localization by generating time and amplitude differences between the ears.How do pinna help locate sound?
3 answersPinna, the external part of the ear, play a crucial role in sound localization. They provide important spectral cues that help in determining the direction of a sound source. The fine structures of the pinna affect the subjective localization of a sound source, with different structures having different effects depending on the incidence angle. Additionally, pinna-imitating (PI) microphone directionality modes in cochlear implants have been shown to improve sound localization and discrimination. PI mode leads to reduced front-back confusions and improved ability to discriminate sound sources at the sides. In children with congenital unilateral conductive hearing loss (UCHL), pinna cues are relied upon for sound localization, even after fitting a bone-conduction device (BCD). Furthermore, a combination of specially designed pinna and profile-based cues have been investigated for vertical sound localization, providing accurate estimates even in noisy environments.What are the key challenges that acoustic textiles face in the coming years?
5 answersAcoustic textiles face several key challenges in the coming years. One challenge is to enhance their performance characteristics to be comparable to conventional acoustic materials such as glass fibre mats and polyurethane foams. Another challenge is to minimize the damage inflicted on the environment throughout the whole life cycle of the textile product. Additionally, the electrical performance of textile circuits woven or knitted within a textile matrix presents unusual constraints due to the textile manufacturing process and the properties of the fibers used. Signal attenuation and the ability to form reliable interconnections are major challenges for distributed sensors connected via an electronic fabric. Furthermore, the competitiveness of products such as cars and washing machines is being considered in terms of noise levels, making noise control an important challenge for acoustic textiles.What are the benefits of incubation centers for women entrepreneurs?
5 answersIncubation centers provide several benefits for women entrepreneurs. They offer tailored assistance and a conducive work environment for new business development. Incubators also provide training, access to market information, and business networks for women's businesses. However, there is a need for contextualization in the services provided by incubators to meet the real needs of women entrepreneurs. Additionally, the attributes of incubators play a role in encouraging women's entrepreneurship, but there is a lack of gender-inclusive practices among the most impactful incubators. To maximize the benefits for women entrepreneurs, it is recommended to adopt behavioral interventions, inclusionary best practices, and provide services tailored to their real needs. Further investments in establishing new incubation centers are also suggested.
