Brain volume changes were found in the CCT showing a significant increase in precuneus volume. Sex moderated the brain volume change in the AE and COMB groups, suggesting that men may benefit more than women. Changes in molecular biomarkers and brain volumes did not significantly mediate the cognitive-related benefits found previously for any group. This study shows crucial initial molecular and brain volume changes related to lifestyle interventions at early stages and highlights the value of examining activity parameters, individual difference characteristics and using a multi-level analysis approach to address these questions.This study evaluated the feasibility of using occipitoparietal alpha activity to drive target/non-target classification in a brain-computer interface (BCI) for communication. EEG data were collected from 12 participants who completed BCI Rapid Serial Visual Presentation (RSVP) calibrations at two different presentation rates 1 and 4 Hz. Attention-related changes in posterior alpha activity were compared to two event-related potentials (ERPs) N200 and P300. Machine learning approaches evaluated target/non-target classification accuracy using alpha activity. Results indicated significant alpha attenuation following target letters at both 1 and 4 Hz presentation rates, though this effect was significantly reduced in the 4 Hz condition. Target-related alpha attenuation was not correlated with coincident N200 or P300 target effects. Classification using posterior alpha activity was above chance and benefitted from individualized tuning procedures. These findings suggest that target-related posterior alpha attenuation is detectable in a BCI RSVP calibration and that this signal could be leveraged in machine learning algorithms used for RSVP or comparable attention-based BCI paradigms.
The US Navy has a long history of responding to disasters around the globe. US Navy ships have unique characteristics and capabilities that determine their capacity for a disaster response. This paper discusses common considerations and lessons learned from three distinct disaster missions.
The 2010 earthquake in Haiti had a robust response with multiple US Navy ship platforms. It was best assessed in three phases an initial mass casualty response, a subacute response, and a humanitarian response. The 2017 response to Hurricane Maria had a significant focus on treating patients with acute needs secondary to chronic illnesses to decrease the burden on the local healthcare system. The COVID-19 response brought distinctive challenges as it was the first mission where hospital ships were utilized in an infectious disease deployment.
The first ships to respond to a disaster will need to focus on triage and acute traumatic injury. After this first phase, the ship's medical assets will need to focus on providing care in a disrupted health care system which most often includes acute exacerbations of chronic disease. Surgeons must be ready to be flexible in their responsibilities, be competent with end-of-life care, and negotiate technical and cultural communication challenges.

We obtain necessary/sufficient criteria for the local equivalence of Gaussian states, independently of the classical results by Araki and Yamagami, Van Daele, Holevo. We also present a criterion for a Bogoliubov automorphism to be weakly inner in the GNS representation. The main application of our analysis is the description of the vacuum modular Hamiltonian associated with a time-zero interval in the scalar, massive, free QFT in two spacetime dimensions, thus complementing the recent results in higher space dimensions (Longo and Morsella in The massive modular Hamiltonian. arXiv2012.00565). In particular, we have the formula for the local entropy of a one-dimensional Klein-Gordon wave packet and Araki's vacuum relative entropy of a coherent state on a double cone von Neumann algebra. Besides, we derive the type III 1 factor property. Incidentally, we run across certain positive selfadjoint extensions of the Laplacian, with outer boundary conditions, seemingly not considered so far.It is known that the eigenfunctions of a random Schrödinger operator on a strip decay exponentially, and that the rate of decay is not slower than prescribed by the slowest Lyapunov exponent. A variery of heuristic arguments suggest that no eigenfunction can decay faster than at this rate. We make a step towards this conjecture (in the case when the distribution of the potential is regular enough) by showing that, for each eigenfunction, the rate of exponential decay along any subsequence is strictly slower than the fastest Lyapunov exponent, and that there exists a subsequence along which it is equal to the slowest Lyapunov exponent.During the Corona pandemic, it became clear that people are vulnerable to potentially harmful nonhuman agents, as well as that our own biological existence potentially poses a threat to others, and vice versa. Vismodegib This suggests a certain reciprocity in our relations with both humans and nonhumans. In his The Visible and the Invisible, Merleau-Ponty introduces the notion of the flesh to capture this reciprocity. Building on this idea, he proposes to understand our relationships with other humans, as well as those with nonhuman beings as having a chiasmic structure to sense, or perceive another entity in a particular way simultaneously implies to be sensed or perceived in a particular way by this other entity. In this paper, we show how a postphenomenological perspective expands on Merleau-Ponty first, it more radically interprets Merleau-Ponty's notion of flesh by not only considering it to be a medium that is the condition of possibility for vision but as pointing to the constitution of an intercorporeal field in which entities-both human and nonhuman-mutually sense one another. Second, it augments Merleau-Ponty's thought by drawing attention to how technologies mediate chiasmic relations. This is clarified through the example of the facemask, which (1) reveals the chiasmic structure of our relation with nonhuman entities, and (2) shows that technologies co-constitute interpersonal relationships by making humans present to one another in a particular way. We suggest that these aspects are not unique to the facemask, but point to a general technologically mediated chiasmic structure of human-world relations.Based on publication data on coronavirus-related fields, this study applies a difference in differences approach to explore the evolution of gender inequalities before and during the COVID-19 pandemic by comparing the differences in the numbers and shares of authorships, leadership in publications, gender composition of collaboration, and scientific impacts. We find that, during the pandemic (1) females' leadership in publications as the first author was negatively affected; (2) although both females and males published more papers relative to the pre-pandemic period, the gender gaps in the share of authorships have been strengthened due to the larger increase in males' authorships; (3) the share of publications by mixed-gender collaboration declined; (4) papers by teams in which females play a key role were less cited in the pre-pandemic period, and this citation disadvantage was exacerbated during the pandemic; and (5) gender inequalities regarding authorships and collaboration were enhanced in the initial stage of COVID-19, widened with the increasing severity of COVID-19, and returned to the pre-pandemic level in September 2020. This study shows that females' lower participation in teams as major contributors and less collaboration with their male colleagues also reflect their underrepresentation in science in the pandemic period. This investigation significantly deepens our understanding of how the pandemic influenced academia, based on which science policies and gender policy changes are proposed to mitigate the gender gaps.The sense of belonging plays an important role in a person's well-being. It also acts as a protective factor against mental distress. Deaf people struggle to fit into the dominant hearing society due to communication barriers. The multi-languages used in Malaysian families add to this communication challenge. Communication breakdown leaves the deaf person socially excluded while a poor sense of belonging also increases their vulnerability to mental health issues. Hence, this study explored the deaf person's sense of belonging and well-being through their social experiences in Malaysia. Baumeister's need-to-belong theory served as the theoretical framework of this study. An Ethnographic approach with in-depth interviews and participant observation was used to explore the social experiences of six Chinese deaf adults, aged 20-37, residing in Ipoh. Their hearing parents were interviewed as well to obtain parents' perspective of the child's well-being in the earlier years. Participants were selected using the purposive and snowballing sampling method. Upon data saturation, thematic analysis was used to identify themes, patterns, and interpret its meanings. The main themes that emerged from the data was the "struggle to fit in", "emotional effect", and "quality social connections". Findings of this study can be used in the formation of policies and strategies to ensure that deaf individuals are not excluded from their communities. Cultivating an inclusive community and developing the deaf community offers a better sense of belonging, which would help increase well-being of deaf people. Future research may focus on deaf identity and well-being of deaf youth in Malaysia.Mechanical ventilator is a machine that is mechanically designed to deliver breathable air in and out of the lungs to provide a breathing mechanism for a patient who is physically unable to breathe, it is an indispensable life-support device in critical care medicine and medical emergencies such as scenarios during the COVID-19 pandemic. This research presents a model design of the pneumatic circuit that is electronically controlled, by using computer-aided pneumatic rig over selected 5/3, 5/2, 3/2 solenoid gating valves, the performance of these valves must be investigated to ascertain the most appropriate valve to be used for the electro-pneumatic mechanical ventilator. An elaborate parametric investigation reported for volume-controlled ventilators illustrate the influences of key parameters on the dynamics of the ventilated respiratory system. This study presents the linearity of tidal volume, peak pressure and lung compliance for the parameters considered. However, the maximum pressure of the ventilation device increases slowly when the tidal volumes exceed 600 ml. In addition, influence of evacuation time of the ventilator predicted over high throughput in time regimes of 1 s; 1.2 s; 1.4 s; 1.6 s, and 1.8 s showed that the pressure platform in the pipe might not appear if the exhaust time of the ventilator is less than 1.6 s. The 5/2 solenoid valve was considered the best with consistent flowrate. The archetypal model of the pneumatic circuit developed in this research could find vital application in the design of patient-interfacing devices particularly in ventilators and neonatal incubator.
