Abstract

The widespread emergence of the COVID-19 pandemic has transformed our lifestyle, and facial respirators have become an essential part of daily life. Nevertheless, the current respirators possess several limitations such as poor respirator fit because they are incapable of covering diverse human facial sizes and shapes, potentially diminishing the effect of wearing respirators. In addition, the current facial respirators do not inform the user of the air quality within the smart facepiece respirator in case of continuous long-term use. Here, we demonstrate the novel smart N-95 filtering facepiece respirator that incorporates the humidity sensor and pressure sensory feedback-enabled self-fit adjusting functionality for the effective performance of the facial respirator to prevent the transmission of airborne pathogens. The laser-induced graphene (LIG) constitutes the humidity sensor, and the pressure sensor array based on the dielectric elastomeric sponge monitors the respirator contact on the face of the user, providing the sensory information for a closed-loop feedback mechanism. As a result of the self-fit adjusting mode along with elastomeric lining, the fit factor is increased by 3.20 and 5 times at average and maximum respectively. We expect that the experimental proof-of-concept of this work will offer viable solutions to the current commercial respirators to address the limitations., Comment: 20 pages, 5 figures, 1 table, submitted for possible publication

Abstract

Simple Summary: Cerebral salt wasting syndrome is defined as a hyponatremic condition due to sodium loss through the kidney during intracranial disorders. A 12-year-old spayed female domestic shorthair cat was referred to our referral animal hospital with tetraplegia and a history of hyponatremia with dehydration from a local hospital after intravenous fluid treatment. The cat was suspected to have intracranial disease after a thorough physical and neurologic examination. MRI revealed bilateral parietal lobe cerebrocortical gray-white matter junction T2/Flair high signal related to rapid electrolyte calibration, and C2 spinal cord ventral area T2 high signal indicated ischemic myelopathy. After 2 days, the cat revisited our hospital with severe lethargy and anorexia. Laboratory examination revealed hyponatremia (136 mEq/L) with dehydration. Through history-taking, laboratory examination, imaging, and fluid therapeutic response, the cerebral salt wasting syndrome was tentatively diagnosed. Electrolytes stabilized after starting treatment with fludrocortisone, and the cat was discharged. After 3 weeks, MRI revealed that the parietal lobe lesion had disappeared; however, the spinal cord ischemic lesion got worse than previous imaging, and the cat was euthanized. This is the first case of suspected cerebral salt-wasting syndrome in a cat. And this syndrome might be included on the differential diagnosis list for cats with intracranial disease, dehydration, and hyponatremia. A 12-year-old spayed female domestic short cat was presented with tetraplegia. The cat also showed signs of hyponatremia and dehydration, which were rapidly corrected by intravenous fluid infusion. Based on thorough physical and neurological examinations, the patient was suspected of having an intracranial disease. MRI revealed a high-signal T2 image of the bilateral parietal cerebral cortical gray matter junction, which is associated with fast electrolyte calibration, and a high-signal T2 image of the C2 spinal cord ventral area, which is associated with ischemic myelopathy. The cat reappeared three days later due to anorexia. Laboratory examinations revealed that the cat was clinically dehydrated and exhibited hyponatremia. Other causes of hyponatremia were excluded through history-taking, laboratory examination, imaging, and therapeutic response to fluid therapy, except for cerebral salt-wasting syndrome (CSWS). The cat was discharged 3 days after the start of fludrocortisone therapy with electrolytes within the normal range. Magnetic resonance imaging (MRI) was performed again 1 month after hospitalization, and the cerebral lesion disappeared, but the spinal cord lesion worsened compared to the previous image. The patient was euthanized due to the progression of the spinal lesion, with a poor prognosis and poor quality of life. This is the first case of suspected CSWS with a cervical spinal lesion in a cat. [ABSTRACT FROM AUTHOR]

28. Nuclear Learning: Nuclear Coercion and the Proliferation Dilemma

Abstract

Since 1945 the United States has not used nuclear weapons to attack other states, yet it has used nuclear coercion more actively than any state. Why did the U.S. use nuclear coercion at all against weak states or for non-vital national interests when the U.S. had superior conventional forces? What would have induced U.S. leaders to employ nuclear coercion? Nuclear deterrence theory and nuclear taboo theory cannot adequately explain why, under similar security and domestic environments, Dwight Eisenhower and Richard Nixon were more willing to use nuclear coercion whereas other leaders like Lyndon Johnson overall abstained from using nuclear threats. I argue that while U.S. leaders’ learning of the overly destructive damages of military nuclear use raised the threshold of using nuclear weapons to attack, the lack of learning or biased learning of the repercussions of coercive nuclear use, especially nuclear proliferation induced by U.S. nuclear threats, allowed many leaders to retain their belief in the coercive power of nuclear weapons. Therefore, they considered and even used nuclear coercion for non-vital matters. Based on the theoretical concepts of nuclear learning and using a historical analysis, my dissertation finds a causal mechanism of nuclear learning that could explain what promoted or hindered learning of the technical and political reality of nuclear weapons and led them to the counterproductive use of nuclear coercion.

Abstract

The arrangement of Xe atoms incorporated in the cavities of a fully dehydrated zeolite A with a unit composition of Cs3Na8HSi12Al12O48 (Cs3-A) has been studied. A Cs3-A crystal was exposed to 255 atm of Xe at 400 degrees C for 7 days and then cooled at pressure to trap the Xe atoms. A second crystal received the same treatment at 450 atm and a third crystal at 1020 atm. Single-crystal x-ray diffraction methods were used in determining the crystal structures in the cubic space group Pm3m at 21 degrees C and 1 atm.

Abstract

Humans now have a life expectancy of nearly 90 years and, as a result, society is rapidly aging. These longer life spans have, however, increased the average length of hospitalization for elderly adults suffering from chronic diseases such as cancer, diabetes, and encephalopathy. In a recent survey of 10 well-being indices for elderly adults, the top demands for well-being are physical, spiritual, and psychological. Thus, we developed the WISH (Well-aging Indexing for Senior Health) Platform to enhance the normalizing exponents using survey data. Nowadays, the incidence of many chronic diseases is increasing. Thus, we designed the WISH Platform using clinical research on depression, cerebral infarction, coronary artery, and rheumatism, which are common diseases in Koreans. By applying this study to chronic diseases, which manifest differently among elderly adults across different countries, it is possible to determine influential nutrition and life patterns to create a standardized index. Such an index will help create value for the happiness of active elderly people, which in turn will aid in their efforts to maintain health, it may even benefit health promotion in other age groups.

Abstract

A 3-year-old neutered female poodle with a long history of dermatophytic skin disease was presented with lethargy, anorexia and progressive weight loss. Abdominal ultrasonography revealed markedly enlarged mesenteric lymph nodes and multiple hypoechoic foci in the spleen. Cytology of the mesenteric lymph nodes and spleen showed granulomatous inflammation with fungal organisms and negatively stained intracytoplasmic bacterial rods consistent with Mycobacteria spp. Based on culture, multiplex polymerase chain reaction and sequence analysis, the bacterium was identified as Mycobacterium avium subspecies hominissuis. Despite treatment with antibiotics, the dog's condition deteriorated, and it died approximately 3 weeks after first presentation.
