As a pandemic‐era collaborative writing project undertaken amid rising geopolitical tensions, this article demonstrates understanding humor in contemporary China as an ethnographic project leading toward deep, empathetic knowledge at a time when in‐person fieldwork became difficult. Through deciphering and translating layered meanings "encrypted" in and intentions signaled by humor in a new comedy program launched in 2021, we dive deep into the lively social life in contemporary China. Humor, via "thick description," offers valuable insights into life in "fieldsites" that were hard to access during the pandemic time, amid political tensions. It provides a unique lens to examine the unspoken but shared sentiments in societies where humor has become a fundamental mode of public expression. It alerts us to existential anxieties in social life, the subtle voices of social critique, and the yearning for empathy. Humor is not only a valuable object for anthropological inquiry but also a vantage point to reflect on ethnographic methodology and epistemology. We examine humor, with its sentimental and ethical potentialities, and through spontaneous collaboration of mutual support, envision new possibilities in anthropological knowledge production.

Objectives: The Life's Simple 7 score (LS7) promotes cardiovascular health (CVH). Despite this, somewith optimal LS7 develop cardiovascular disease (CVD), while others with poor CVH do not, termed the "CVH paradox." This paper explores pathways explaining this paradox. Methods: We examined methodological aspects: 1) misclassification bias in self-reported lifestyle factors (smoking, physical activity, diet); 2) cumulative exposure to risk factors over a lifetime, impacting the CVH paradox. Punctual risk factor assessments are suboptimal for predicting outcomes. We proposed personalized prevention using "novel" elements to refine CVH assessment: 1) subclinical vascular disease markers, 2) metabolic biomarkers in blood and urine, 3) emerging risk factors, 4) polygenic risk scores (PRS), 5) epigenetics, and 6) the exposome. Results: Addressing the CVH paradox requires a multifaceted approach, reducing misclassification bias, considering cumulative risk exposure, and incorporating novel personalized prevention elements. Conclusion: A holistic, individualized approach to CVH assessment and CVD prevention can better reduce cardiovascular outcomes and improve population health. Collaboration among researchers, healthcare providers, policymakers, and communities is essential for effective implementation and realization of these strategies. [ABSTRACT FROM AUTHOR]

The safety of SCUBA divers remains at high risk in deep-sea owing to multiple factors such as dangerous surrounding, rely upon technical equipment necessary for life support, decreased underwater navigation, and communication infrastructure. Gradual decrease and increase in water temperature and pressure corresponding to depth are among the most common problems that cause most of the fatalities in deep-sea diving. Therefore, different gadgets for accurate measurement of vital parameters, reliable navigation, and seamless communication are of prime importance. In this paper, we propose an all-optical technique for local and remote monitoring of underwater temperature and pressure for deep-sea SCUBA divers based on fiber Bragg grating (FBG) sensors and underwater optical communication-single mode fiber (UWOCSMF) integrated transmission system. The proposed technique is implemented using two FBG temperature and pressure sensors fixed over diver's suit and UWOC-SMF integrated transmission system for simultaneous local and remote monitoring of underwater temperature and pressure. Remote monitoring of underwater temperature and pressure is achieved at ship station through a remotely operated underwater vehicle (ROV) and UWOC-SMF integrated transmission system by means of shifts in the original Bragg wavelengths of sensors due to temperature and pressure variations. The performance of the sensors is analyzed for pressure and temperature in the range of 0 to 6.4 MPa (≈0 to 655mH2O) and 40 to -2°C, respectively corresponding to different depths. The results show that the proposed technique can work well in the deep ocean over a range of pressures and temperatures of 0-7 MPa and 40 to -2°C while achieving a temperature sensitivity of 4.3 p.m./°C and a pressure sensitivity of 30.5 p.m./MPa. Clear spectra of reflected signals from FBG sensors at ship station are achieved after signal transmission over UWOC-SMF hybrid link. [ABSTRACT FROM AUTHOR]

Networks of marine protected areas (MPAs) are being increasingly implemented worldwide as conservation management tools. We report here on MPA effectiveness using data from a 17‐year long remotely operated vehicle (ROV) monitoring program spanning mesophotic (~ 20–130 m) depths in 26 MPAs across California's MPA network. We utilize a spatial modeling approach that includes important environmental covariates as well as spatial dependence in the data, and allows the separation of statewide and regional trends in the abundance of focal species from additional trends specific to MPAs. We demonstrate that there have been statewide and/or regional recoveries in abundance for the majority of our 10 focal demersal fish species, with all four statewide species assessments and 18 out of 22 species‐region combinations assessed displaying positive trends. We also demonstrate that MPA protection has had an additional positive effect on the abundance of the majority of these focal species inside MPAs compared with reference areas, with positive effects for all four statewide species, and 18 out of 22 statewide/regions assessed showing positive effects, four showing no statistically detectable differences, and no negative MPA effects found. Comparisons with theoretical expectations of MPA recovery for our focal species showed that 2 out of 4 statewide, and 11 out of 17 species‐region combinations assessed displayed higher mean MPA effects than expected. Our results highlight strong trajectories of increasing abundance and additional MPA effects for many of our focal species, demonstrating that MPAs are having positive effects in mesophotic depths across the network as well as at previously reported shallower depths, and that image‐based platforms such as ROVs provide an important tool to support timely reporting on the effectiveness of MPA networks.

In this paper, I present the idea that the documentary film My Octopus Teacher (Ehrlich & Reed) is an evocative allegory for some key threads in the ongoing learning at the heart of psychotherapy. On the one hand, the film is a narrative about a relationship formed between the narrator and documentary‐maker Craig and an octopus that he encounters in daily dives in an underwater kelp forest. On the other hand, it is a story–dream of a man and an octopus who swim together in the proto‐mental seas of the unconscious, a space where fluidity and symmetry rule, and where the boundaries between I and thou dissolve. Alongside the theme of mutual dream work, the documentary presents an evocative allegory of what it takes to practice as a therapist: the maps of our own disintegration that inform our work, and the key dispositions of learning to watch and observe and to fine tune our faith.

Simple Summary: Our study provides the first record of Pacific sleeper sharks in 1629 m deep waters off the southeast coast of Hainan Island in the South China Sea. At a site, we placed a dead cow as bait and a metal-framed cage with cameras and observed eight individuals and their feeding activities by using ROV diving. The record indicates an expansion of the known distribution range of the Pacific sleeper sharks to the west of the northern South China Sea. Such a finding demonstrates that the habitat ranges of large animals are far wider in deep seas than we know from observations in the upper layer, and habitat expansion of some animal populations may have already taken place under intensive anthropogenic influences such as climate changes. We conducted an experiment of planting a dead cow and a metal-framed cage with cameras on the 1629 m deep sea floor off the southeast coast of Hainan Island in the northwestern South China Sea, using ROV diving and setting up a video camera on the cage to observe animals who came to eat the bait. The deep-sea cameras captured footage of eight Pacific sleeper sharks (Somniosus pacificus) swimming and feeding around the dead cow. To our knowledge, this is the first time the occurrence of such a shark species has been reported in the South China Sea. Eight individuals were differentiated based on the characteristic differences displayed in the images, with lengths of 1.9 to 5.1 m estimated. The video camera also recorded the predators' behavior of tearing at the dead cow on the seabed. It was discovered that Pacific sleeper sharks are not strictly solitary and exhibit queue-feeding behavior. This study is significant as it documents a record of a data-scarce shark species, for which little information is available in the literature. It also documents an expansion of the species' known habitat from the north Pacific Ocean into the South China Sea. Such sharks diving into the deep sea to predate on dead animals also suggests that occurrences of large chunks of dead organic bodies falling onto the deep sea might have been more frequent than we previously thought in the South China Sea. The findings have implications for understanding the geographic connectivity of large swimming animals between the South China Sea and the Pacific Ocean and provide scientific evidence for formulating conservation and management strategies for sharks and other large animals in the oceans.

Psychological reattachment to work means mentally reconnecting with one's work before or upon returning to work in the morning. Recent studies revealed its potential to boost daily work engagement, demonstrating its relevance to research and practice. Despite this, no studies have explored the components of psychological reattachment and why and how employees reattach to their work. Yet, to expand the theoretical understanding of psychological reattachment and to apply its potential in practice, it is crucial to dive deeper into the details around this process. Therefore, this study employs a qualitative approach to test existing theoretical assumptions on psychological reattachment, uncover additional manifestations of psychological reattachment, examine its unfolding process, and identify potential predictors, benefits, and drawbacks. Our methodological procedure comprises the multi-coding of qualitative material from 35 employees with diverse backgrounds. One of our main findings is that when anticipating upcoming demands during the workday, employees also anticipate how to meet those demands. Furthermore, the more demands are expected, the longer it takes employees to mentally reattach to their work. This hints at how psychological reattachment might resemble a preventive coping mechanism for job demands during the day. [ABSTRACT FROM AUTHOR]

This article explores how citizens’ legitimacy perceptions are affected when decision makers deviate from the recommendations of a deliberative mini‐public (DMP), and what can be done to mitigate negative consequences. The results of a preregistered vignette experiment in Belgium (N = 2659) support our two main expectations. First, citizens’ legitimacy perceptions decrease when politicians do not follow the outcome of a DMP. Second, when politicians communicate responsively about this – meaning that they show respect for the recommendations and publicly justify why they deviated from them – legitimacy perceptions substantially increase, generally reaching the level of those cases where recommendations are followed. Diving deeper into this result also shows that for this effect to occur, citizens must find the provided reasoning valid and acceptable. Finally, the results hold among both policy winners and policy losers. These findings have implications for the literature on democratic innovations, empirical legitimacy, and political representation, but also for policymakers striving to combine arrangements of public participation that go beyond triviality, with political responsibility for the whole, and sustained mechanisms for accountability.

In the dynamic landscape of biomedical science, the pursuit of effective treatments for motor neuron disorders like hereditary spastic paraplegia (HSP), amyotrophic lateral sclerosis (ALS), and spinal muscular atrophy (SMA) remains a key priority. Central to this endeavor is the development of robust animal models, with the zebrafish emerging as a prime candidate. Exhibiting embryonic transparency, a swift life cycle, and significant genetic and neuroanatomical congruencies with humans, zebrafish offer substantial potential for research. Despite the difference in locomotion--zebrafish undulate while humans use limbs, the zebrafish presents relevant phenotypic parallels to human motor control disorders, providing valuable insights into neurodegenerative diseases. This review explores the zebrafish's inherent traits and how they facilitate profound insights into the complex behavioral and cellular phenotypes associated with these disorders. Furthermore, we examine recent advancements in high-throughput drug screening using the zebrafish model, a promising avenue for identifying therapeutically potent compounds. [ABSTRACT FROM AUTHOR]

Birt-Hogg-Dubé syndrome is a rare autosomal dominant hereditary disorder caused by a genetic mutation in the folliculin (FLCN) gene, characterized by benign fibrofolliculomas, increased risk of kidney tumors, lung cysts, and spontaneous pneumothorax. Genetic counseling for a mutation in the FLCN gene is recommended if specific criteria are met. Family members are eligible for genetic testing starting at age 20. For these patients, prevention of pneumothorax is crucial by avoiding deep-sea diving and smoking. Imaging of the kidneys is recommended due to the increased risk of renal cell carcinoma. An MRI scan should be performed at initial presentation, followed by annual monitoring through ultrasound. If kidney surgery is recommended, kidney-sparing surgery is preferred over radical nephrectomy due to the high risk of (contralateral) recurrence. [ABSTRACT FROM AUTHOR]

Latin American marxism, understood as a category, phenomena and process hasn’t been studied broadly, despite how fruitful the Marxist tradition has been in our region. It is proposed in the next pages a series of theoretical-methodological approaches and coordinates to push out into its analysis, respecting the analytical plurality and heterogeneity that characterizes it, describing its enunciation origins and development and outlining the essential ingredients that separate it from other approaches giving its specificity within Latin American critical social thought. The purpose of the article is to provide the researcher a basic framework to dive into deeper inquiries that concern the different topics circumscribed to the marxisms in Latin America.

The Mediterranean spearfish (Tetrapturus belone) is a highly migratory predator, also exploited by commercial and recreational fisheries although its catches are poorly reported. The fishing pressure on this species is currently unknown because catch and landing data are fragmentary. Furthermore, more ecological information (e.g. migratory movements) is needed to establish eventual management measures, and ICCAT has not examined the population status yet. Understanding species migratory movements is crucial for addressing conservation challenges and supporting management decisions. In this study we investigated the migratory movements, seasonal patterns, vertical behavior, and thermal preference of T. belone, with the aim to improve information on its ecology and behavior. Overall, six individuals were tagged in the Strait of Messina and Tyrrhenian Sea with pop-up satellite tags and their movements were mainly restricted to the central Mediterranean. Utilization distributions derived from geolocation revealed an overall and seasonal importance of the Tyrrhenian Sea and Strait of Sicily, as well as variability in winter habitat use. While the fish exhibited similar depth preference, spending the majority of time at depths ≤ 10 m, we observed that the Mediterranean spearfish is also able to perform sporadic deep dives below 200 m. Vertical movement showed a bimodal pattern common in other billfish species, characterized by occupation of shallower, warmer waters during the night and deeper, cooler waters during the day. This research increases knowledge on the migration ecology and habitat preference of T. belone which is important for management of this understudied species. [ABSTRACT FROM AUTHOR]

Digital twins (DTs) have become a widely discussed subject, believed to have the potential to solve various problems across different industries, including Engineering & Construction (E&C). However, there is still significant misconception concerning the definition of DTs and their purpose within E&C. This study dives deep into identifying DT applications within E&C and the other prominent industries, i.e., Aerospace & Aviation, Manufacturing, Energy & Utilities, Automotive, Healthcare, Smart Cities, Oil & Gas, and Retail. The main challenges to the evolution of DT practical applications are also analyzed. A combination of a literature review, multi-case study analysis, and comparative analysis compose the deployed methodology. Standardization and a maturity level classification are proposed to drive progress of the adoption of DTs. The distinct aspects of the different industries and their assets are evaluated to the conclusion that DTs are better employed for maintenance of structures within E&C. DTs have become a well-worn topic, but the abundance of complex theoretical frameworks is met with simple or inexistent practical applications. Therefore, the novelty of this study lays in its comprehensive analysis of DT applications and real-world implementations—a departure from the often-theoretical discussions surrounding DTs.

Purpose: This short paper builds on and critiques work presenting potential non-disasters: disasters that did not seem to happen despite a major hazard. Previous work does not differentiate among different types of potential non-disasters. This short paper uses local information to propose three categories according to reasons for vulnerability being low or absent. These proposed categories are used to critique the construct of "potential non-disasters". Design/methodology/approach: This short paper uses a subjective approach to examples of potential non-disasters in 2022, focusing on local information that describes what happened. This information is applied and analysed for the three proposed categories using examples from Japan, Nepal, the Philippines and Vietnam. Such comparisons are useful for critiquing "potential non-disasters", by understanding better local approaches and information available for reporting on situations that could be disasters. Findings: Potential non-disasters remain relevant for exploring mechanisms, tools and actions for educating about vulnerability causes and vulnerability reduction to avert disasters. Limitations are evident by relying on media reports, even local ones with local authors. A suggestion is to implement a grant programme for collecting data immediately after a major hazard without an evident, major disaster. Additionally, an annual report and critique of each year's potential non-disasters, categorised and analysed, would help to evidence the presence and limits of the "potential non-disaster" construct. Originality/value: This short paper contributes a much deeper theoretical dive into understanding potential non-disasters, both describing them and the drawbacks of the construct. To practitioners, the construct now offers more avenues for actions while illustrating their effectiveness in reducing vulnerabilities. Thus, this paper supports multiple, linked pathways towards more non-disasters. [ABSTRACT FROM AUTHOR]

In this forum paper, I grapple with critical questions about our understanding of science as a discipline and the education standards formulated within that framing. My exploration is contextualized in our current socio-political climate and is presented in discourse with Charity Winburn's Meeting the needs of the individual student in the post-pandemic era: an analysis of the next generation science standards. I draw on Winburn's astute observations about the narratives and epistemologies that shape our current science standards as a springboard for diving deeper into questions about the ways of knowing and types of knowledge traditions that are uplifted in US science education. Through a dialogic process, I outline a critical analysis of the myth of neutrality, the prioritization of epistemologies, and the standardization of learning ingrained in traditional science curricula. I conclude by building on Winburn's hopes for science education with my own aspirations for bringing joy into our collective science learning experiences. [ABSTRACT FROM AUTHOR]

Autism is heterogeneous at many levels, including clinical symptoms and etiology. A key strategy in studying heterogeneous conditions is having large enough sample sizes to stratify into smaller groups that are more homogeneous. SPARK and Simons Searchlight are large and growing research cohorts of individuals with autism in the United States and individuals with genetically defined neurodevelopmental conditions around the world, respectively. They both provide freely available phenotypic and genotypic data with the ability to re-contact participants through the research match program. Deep dives into each gene in Searchlight provide comprehensive natural history data to understand the differing clinical courses to inform proper clinical care, and work toward treatment for each condition. Moreover, pilots of genetically based newborn screening programs for neurogenetic disorders can provide opportunities for equitable and early diagnosis to try to improve outcomes with earlier interventions.

Deep ocean foraging northern elephant seals (Mirounga angustirostris) consume fish and squid in remote depths of the North Pacific Ocean. Contaminants bioaccumulated from prey are subsequently transferred by adult females to pups during gestation and lactation, linking pups to mercury contamination in mesopelagic food webs (200–1000 m depths). Maternal transfer of mercury to developing seal pups was related to maternal mercury contamination and was strongly correlated with maternal foraging behavior (biotelemetry and isotopes). Mercury concentrations in lanugo (hair grown in utero) were among the highest observed worldwide for young pinnipeds (geometric mean 23.01 μg/g dw, range 8.03–63.09 μg/g dw; n = 373); thus, some pups may be at an elevated risk of sub-lethal adverse health effects. Fetal mercury exposure was affected by maternal foraging geographic location and depth; mercury concentrations were highest in pups of the deepest diving, pelagic females. Moreover, pup lanugo mercury concentrations were strongly repeatable among successive pups of individual females, demonstrating relative consistency in pup mercury exposure based on maternal foraging strategies. Northern elephant seals are biosentinels of a remote deep-sea ecosystem. Our results suggest that mercury within North Pacific mesopelagic food webs may also pose an elevated risk to other mesopelagic-foraging predators and their offspring. [ABSTRACT FROM AUTHOR]

ANNs have become a cornerstone in efficiently managing building energy management systems (BEMSs) as they offer advanced capabilities for prediction, control, and optimization. This paper offers a detailed review of recent, significant research in this domain, highlighting the use of ANNs in optimizing key energy systems, such as HVAC systems, domestic water heating (DHW) systems, lighting systems (LSs), and renewable energy sources (RESs), which have been integrated into the building environment. After illustrating the conceptual background of the most common ANN architectures for controlling BEMSs, the current work dives deep into relative research applications, thereby exhibiting their methodology and outcomes. By summarizing the numerous impactful applications during 2015–2023, this paper categorizes the predominant ANN-based techniques according to their methodological approach, specific energy equipment, and experimental setups. Grounded in the different perspectives that the integrated studies illustrate, the primary focus of this paper is to evaluate the overall status of ANN-driven control in building energy management, as well as to offer a deep understanding of the prevailing trends at the building level. Leveraging detailed graphical depictions and comparisons between different concepts, future directions, and fruitful conclusions are drawn, and the upcoming innovations of ANN-based control frameworks in BEMSs are highlighted.

Physiological embryogenesis and adult tissue homeostasis are regulated by transforming growth factor‐β (TGF‐β), an evolutionarily conserved family of secreted polypeptide factors, acting in an autocrine and paracrine manner. The role of TGF‐β in inflammation, fibrosis, and cancer is complex and sometimes even contradictory, exhibiting either inhibitory or promoting effects depending on the stage of the disease. Under pathological conditions, especially fibrosis and cancer, overexpressed TGF‐β causes extracellular matrix deposition, epithelial–mesenchymal transition, cancer‐associated fibroblast formation, and/or angiogenesis. In this review article, we have tried to dive deep into the mechanism of action of TGF‐β in inflammation, fibrosis, and carcinogenesis. As TGF‐β and its downstream signaling mechanism are implicated in fibrosis and carcinogenesis blocking this signaling mechanism appears to be a promising avenue. However, targeting TGF‐β carries substantial risk as this pathway is implicated in multiple homeostatic processes and is also known to have tumor‐suppressor functions. There is a need for careful dosing of TGF‐β drugs for therapeutic use and patient selection. [ABSTRACT FROM AUTHOR]

Studying the behavior of pelagic sharks can be challenging due to the logistical difficulties of locating migratory individuals in the open ocean. This is further compounded by their rarity in certain ocean regions due to overfishing. The accessibility of deep-water basins in The Bahamas provides a unique model system for describing how pelagic sharks connect surface and deep ocean habitats through vertical behavior. Using custom deep-sea landers in The Bahamas, we provide novel depth data for two species of pelagic sharks: a depth range extension for the dusky shark at 767 m and novel occurrence at twilight zone depth for the silky shark at 470 m. These observations expand the vertical niche for these two species, suggesting that deep diving behavior is likely more common than previously thought and likely important for ecosystem connectivity.

This article provides a historical account of deep-diving trials conducted by the Royal Navy in the early 20th century. The trials aimed to improve the safety and effectiveness of deep-sea diving by testing new equipment and techniques. Divers faced challenges such as CO2 poisoning, equipment malfunctions, and decompression sickness. The article also highlights the record-breaking achievement of Frederick Hilton, who unintentionally set a world record for deep diving in 1930. The Royal Navy used the findings from these trials to develop decompression tables and explore the use of helium/oxygen breathing mixtures. However, further experiments were halted due to the outbreak of World War II. [Extracted from the article]

Purpose: The broader analytical framing of systematically distorted communication (SDC) helps extract value out of the enormous amount of scholarship on fake news. Design/methodology/approach: The massive literature on fake news has been the subject of handbook overviews, systematic literature reviews, summaries, taxonomies, citation studies and so on. Deploying these tools, the approaches that the literature takes can be characterized, Habermas' concept of systematically distorted communication (SDC) will then be presented in its context, reviewed and put to work to frame fake news research to tell us new things that individual pieces of specific analysis and research do not. Conclusions will be offered from this analysis. Findings: Fake news research has become repetitive, revolving around themes such as the fate of journalism, the role of technology, remediating its effects and deep dives into definitional components (disinformation, misinformation, lies and so on). A broader framing of systematically distorted communication allows us to arrive at some conclusions about contemporary fake news: that it is a power strategy with a particular right-wing slant and it creates a sociology – that is, its own interpretive environment – hostile to democratic functioning. It answers the question: what is fake news for? Originality/value: A perspective on fake news research is much needed and Habermas' concept is a useful framing mechanism for the large corpus of research. Systematically distorted communication asks – and answers – different questions of the research. Meanwhile, SDC itself is modified by its application to fake news research and contemporary conditions. [ABSTRACT FROM AUTHOR]

The oceans contain 1,335 million km3 of water covering 361.9 million km2 of seafloor across 71% of the planet. In the past few decades, there has been substantial effort put into mapping and exploring the ocean fueled by the advent of new technologies that more easily enable deepwater access. However, we are still far from achieving our shared goals of a well characterized and documented ocean. In 2010, Webb et al. documented the paucity of deep-sea data in general, with a specific focus on the lack of pelagic records in the Ocean Biogeographic Information System OBIS, which is the largest of the ocean biodiversity archives. While significant exploration progress has been made, the rate of change in the ocean is outstripping the rate of characterization and research. Given the limited resources available, future work needs to be prioritized to focus on areas of greatest need. Here, we investigated several lines of inquiry to determine priority areas for future exploration. We accumulated the largest database of global deep submergence dive records ever compiled and used it, plus OBIS biodiversity records, to assess the level of exploration in different ocean regions. Then, we compared these measures of exploration effort with different biogeographic province schemas and estimates of climate change velocity projections to identify the largest remaining gaps in exploration and research sampling. Given that marine science has only explored between 5 and 20% of the ocean (depending on estimates) in the last hundred and fifty years, future exploration needs to be more targeted to attempt to keep pace with the rate and impact of environmental and biodiversity change in the ocean.

Dreams have the potential provide intimate access to psychotherapy clients' inner lives. When therapists are able to help clients experience their dreams in a curious, open, focusing-oriented way, the client gains direct access the dream's tendency to carry their life situation forward. This paper offers evidence of a paradigm shift away from analytic to experiential, client-centered approaches to dreams. It then describes three experiential dreamwork practices: finding the help in a dream (from focusing), re-entering a dream element (from Gestalt) and dreaming the dream onward (from Jung). Included are several clinical and personal examples which show how entering a dream experientially allows the dreamer to discover something new and how this often leads to a change-moment or, in focusing terms, a felt shift. Several clinical and personal examples illustrate that while dreams may be helpful in their own right, engaging deeply with them in an experiential way allows their fuller potential for personal growth and forward movement to be realized. Over time, this way of engaging with dreams can become a natural ongoing undercurrent, both in dreaming and waking, that is always available and evolving. [ABSTRACT FROM AUTHOR]

The acoustic ecology of sei whales (Balaenoptera borealis) is poorly understood due to limited direct observation of the behavioral context of sound production and individual behavior. Suction cup–attached acoustic recording tags were deployed on sei whales to unambiguously assign call types and explore the acoustic behavior of this endangered species. Twelve tag deployments resulted in ∼173 h of acoustic data and 1030 calls. Sound types included downsweeps and three previously undescribed call types. Knocks were short duration (<1 s), with an average peak frequency of 330 Hz. Pulse type 1 and pulse type 2 calls, typically produced in sequences, were short in duration (0.08 and 0.28 s) and low in average peak frequency (50 and 26 Hz), with relatively high received levels. Average call rates for all call types combined were three calls per hour, but increased during twilight. Sex differences in call type usage included a higher use of pulses by females and knocks by males. Calls were almost exclusively produced at depths <10 m, although whales rarely dove deeper in this study. These data provide a more comprehensive picture of the acoustic and behavioral ecology of sei whales than previously possible, which can inform future conservation efforts for this endangered species.

The article discusses the history of reinforced straps on diving helmets, specifically focusing on Augustus Siebe's original design. The reinforced strap was a feature of Siebe's 12-bolt breastplate design, which created a waterproof seal between the helmet and diver's dress. While Siebe eventually abandoned the reinforced strap, it was occasionally used by other manufacturers. The article also mentions other manufacturers, such as Morse, Cabirol, Scauda, John Date, and Heinke, who incorporated reinforced straps into their diving helmets. The author provides images and references to further explore the topic. [Extracted from the article]

Introduction: While gas narcosis is familiar to most divers conducting deep (> 30 metres) dives, its effects are often considered minuscule or subtle at 30 metres. However, previous studies have shown that narcosis may affect divers at depths usually considered safe from its influence, but little knowledge exists on the effects of gas narcosis on higher cognitive functions such as decision-making in relatively shallow water at 30 metres. Impaired decision-making could be a significant safety issue for a multitasking diver. Methods: We conducted a study exploring the effects of gas narcosis on decision-making in divers breathing compressed air underwater. The divers (n = 22) were evenly divided into 5-metre and 30-metre groups. In the water, we used underwater tablets equipped with the Iowa Gambling Task (IGT), a well-known psychological task used to evaluate impairment in decision-making. Results: The divers at 30 metres achieved a lower score (mean 1,584.5, standard deviation 436.7) in the IGT than the divers at 5 metres (mean 2,062.5, standard deviation 584.1). Age, body mass index, gender, or the number of previous dives did not affect performance in the IGT. Conclusions: Our results suggest that gas narcosis may affect decision-making in scuba divers at 30 metres depth. This supports previous studies showing that gas narcosis is present at relatively shallow depths and shows that it may affect higher cognitive functions. [ABSTRACT FROM AUTHOR]

Purpose: To examine the effect of freediving depth on risk for hypoxic blackout by recording arterial oxygen saturation (SpO2) and heart rate (HR) during deep and shallow dives in the sea. Methods: Fourteen competitive freedivers conducted open-water training dives wearing a water-/pressure proof pulse oximeter continuously recording HR and SpO2. Dives were divided into deep (> 35 m) and shallow (10–25 m) post-hoc and data from one deep and one shallow dive from 10 divers were compared. Results: Mean ± SD depth was 53 ± 14 m for deep and 17 ± 4 m for shallow dives. Respective dive durations (120 ± 18 s and 116 ± 43 s) did not differ. Deep dives resulted in lower minimum SpO2 (58 ± 17%) compared with shallow dives (74 ± 17%; P = 0.029). Overall diving HR was 7 bpm higher in deep dives (P = 0.002) although minimum HR was similar in both types of dives (39 bpm). Three divers desaturated early at depth, of which two exhibited severe hypoxia (SpO2 ≤ 65%) upon resurfacing. Additionally, four divers developed severe hypoxia after dives. Conclusions: Despite similar dive durations, oxygen desaturation was greater during deep dives, confirming increased risk of hypoxic blackout with increased depth. In addition to the rapid drop in alveolar pressure and oxygen uptake during ascent, several other risk factors associated with deep freediving were identified, including higher swimming effort and oxygen consumption, a compromised diving response, an autonomic conflict possibly causing arrhythmias, and compromised oxygen uptake at depth by lung compression possibly leading to atelectasis or pulmonary edema in some individuals. Individuals with elevated risk could likely be identified using wearable technology. [ABSTRACT FROM AUTHOR]

The escalating utilization of pesticides has led to pronounced environmental contamination, posing a significant threat to agroecosystems. The extensive and persistent global application of these chemicals has been linked to a spectrum of acute and chronic human health concerns. This review paper focuses on the concentrations of airborne pesticides in both indoor and outdoor environments. The collection of diverse pesticide compounds from the atmosphere is examined, with a particular emphasis on active and passive air sampling techniques. Furthermore, a critical evaluation is conducted on the methodologies employed for the extraction and subsequent quantification of airborne pesticides. This analysis takes into consideration the complexities involved in ensuring accurate measurements, highlighting the advancements and limitations of current practices. By synthesizing these aspects, this review aims to foster a more comprehensive and informed comprehension of the intricate dynamics related to the presence and measurement of airborne pesticides. This, in turn, is poised to significantly contribute to the refinement of environmental monitoring strategies and the augmentation of precise risk assessments. [ABSTRACT FROM AUTHOR]

This study presents the design of an underwater superlimb as a wearable robot, providing divers with mobility assistance and freeing their hands for manipulating tools underwater. The wearable design features a thrust vectoring system with two 3D‐printed, waterproofed modules. The module with adjustable connections and strapping holes is designed to enable reconfiguration for multiple purposes, including regular use as an underwater superlimb for divers, manually operated as a handheld glider for swimmers, combined with an amphibian, legged robot as a quadruped superlimb, and coupled as a dual‐unit autonomous underwater vehicle for underwater navigation. The kinematics and dynamics of the prototype and all of its reconfigured modes are developed. A sliding‐mode controller is also introduced to achieve stable simulation in PyBullet. Field tests further support the feasibility of the underwater superlimb when worn on a test diver in a swimming pool. As the first underwater superlimb presented in the literature, this study opens new doors for supernumerary robotic limbs in underwater scenarios with multifunctional reconfiguration.

Aerial–aquatic robots have promising applications due to their ability to operate in air and water with different motion modes. However, challenges such as water/air transition and multimedia movement still limit their development. Inspired by the aerial–aquatic behavior of wild ducks, an aerial–aquatic robot with tunable tilting motors and a delta wing is introduced. The robot can perform multimode motion, including flying in air, swimming on the water surface, transitioning between air and water, and diving underwater. Besides, the buoyancy design enables the robot to float at the air–water interface without consuming energy. Herein, the performance of the robot, including vertical and horizontal cross‐media performance, power consumption, and endurance in various motion modes, is evaluated. The field experiments show that the proposed robot possesses multimode motion and high maneuverability. This study provides a new idea for the structural design of next‐generation practical aerial–aquatic robots. [ABSTRACT FROM AUTHOR]

There is an ongoing need to understand whether transplantation during acute Coronavirus disease 2019 (COVID‐19) can be performed safely, especially when urgent transplant is required. We collected retrospective data of all consecutive non‐lung transplant recipients who had a positive SARS‐CoV‐2 polymerase chain reaction (PCR) on the day of planned deceased donor organ implantation. Data were collected from two large transplant centers from 01/01/2022 to 02/01/2023. Demographics, details regarding COVID‐19 infection, waitlist priority, and details regarding transplantation were obtained. A descriptive analysis was performed. A total of 12 patients were identified: 7 renal, 4 liver, and 1 heart transplant recipient. All 12 patients were vaccinated for COVID‐19. Ten were asymptomatic outpatients found positive on admission and transplanted immediately. Two were in‐patients with mild COVID‐19 symptoms and were reactivated on the waitlist following 3 days of remdesivir when no progression to severe COVID‐19 occurred. Most patients (10/12) received remdesivir posttransplant. No complications attributed to COVID‐19 were noted nor were any secondary family or healthcare worker infections observed. All recipients were managed with special isolation precautions befitting their potentially infectious state. Standard induction therapy was used in all recipients. After a median follow up period of 143 days (interquartile range: 96–201 days), 3 episodes of rejection were documented, 2/7 renal recipients experienced delayed graft function, and 2/4 liver recipients required renal replacement therapy. Graft and patient survival were 100%. Transplantation can safely proceed in select, minimally symptomatic, non‐lung recipients with a positive SARS‐CoV‐2 PCR at the time of transplant.

Is it possible to intellectually grasp the production of architecture in China over the past four decades? How should we make sense of such an unprecedented transformation of the built landscape in human history? Based on a three-year study by the editor H. Koon Wee, the book The Social Imperative: Architecture and the City in China presents a "sourcebook" that gathers multiple entanglements between architecture and society of China's economic reform era. This review attempts to provide an architectural-geographical perspective for readers to dive into this deep volume of collected essays: the socio-economic rapport between China's coastal regions and the hinterland. By situating architecture's "social imperatives" between geographies, this review presents a lateral reading across this multidisciplinary volume of work that would inform both practitioners and the broader audience on understanding the complex forces behind the process of architecture and the city, and contemplating the future role of the architect in, around, and beyond China.
