Aquatic ecosystem monitoring is important for supporting biodiversity and environmental stability, yet it faces increasing threats from pollution, climate change and human activities. This study presents the development and deployment of a low-cost multi-sensor data logging system for real-time monitoring of Lagos Lagoon. The system integrates temperature sensors, hydrophones, and imaging devices to collect environmental data. Results showed that temperature variations ranged from ~28.5 to 31.5 °C, with fluctuations influenced by partial and full submersion. Acoustic analysis revealed dominant frequencies below 500 Hz, indicative of biological and anthropogenic activity in the lagoon. Machine learning models trained on 31 species closely agreed with the environmental dataset despite some noticeable deviations, suggesting potential improvements through data augmentation and model refinement. Despite challenges such as signal attenuation in submerged conditions and image degradation due to water turbidity, the system successfully recorded and logged environmental parameters. This study demonstrates the feasibility of using artificial intelligence-powered, cost-effective sensor technology for continuous aquatic monitoring, with implications for biodiversity conservation and water resource management. Future research should focus on enhancing wireless communication, refining species detection algorithms and improving sensor resilience in harsh aquatic conditions.
This study examines the role of the timing of obligatory disambiguating information – obligatory cues – and presence/absence of optional morphological markers in resolving temporary syntactic ambiguity in Spanish object relative clauses. Native adult comprehension (Study 1) reveals similar accuracy for clauses with relatively early obligatory cues, regardless of the presence/absence of additional markers, and those with late obligatory cues with additional markers, but reduced accuracy for those with late obligatory cues without additional markers. Given the phonetic resemblance of the late-disambiguated variant with its corresponding subject relative, we conduct two follow-up perceptual identification tasks with the whole relative clause, including the head (Study 2), and relative clause fragments (Study 3). The identification tasks show that, when instructed to attend to the form of the structures, participants perceive acoustic differences but retain a bias towards subject-relative interpretations. Our results suggest that additional markers aid comprehension of non-canonical structures when obligatory cues occur relatively late within the structure and highlight the dominance of predictive processing over perceptual information in such cases of late disambiguation.
There has been limited research into the effectiveness of penetrating captive bolt (PCB) for stunning horses (Equus caballus) at slaughter. This study observed 100 horses at a commercial abattoir in Mexico, stunned using pneumatic PCB. Animals were assessed at the time of stunning and immediately after for signs of effective/ineffective stunning and shot positioning, with macroscopic gross brain pathology conducted to determine brain trauma. Twenty-five percent (25/100) received more than one shot and 28% (28/100) displayed behavioural signs of ineffective stunning. Of these 28 animals, all had deviations of more than 10 mm from the suggested shot position outlined by the Humane Slaughter Association with rostral-caudal deviation associated with an absence of damage to the thalamus, midbrain, and pons. Forty-four percent (44/100) of animals displayed no damage to critical brain structures (thalamus, midbrain, pons and medulla), with this associated with ineffective stunning. Overall, 16% of shots missed the brain (16/100), with a higher proportion of poll shots (30%) missing the brain compared to frontal shots (12%). There is the potential, when animals are shot into the poll, for paralysis from damage to the spinal cord and caudal brainstem structures. Appropriate position, angle and performance of PCB is therefore vital to achieving an effective stun, by targeting critical brain structures responsible for maintaining consciousness and ensuring proper PCB maintenance. Animals should be routinely checked between stunning and exsanguination, with minimal time between these stages, to minimise recovery of consciousness and alleviate suffering for horses at slaughter.
One of the central insights of critical and constructivist International Relations (IR) scholarship is that identity-seeking matters in world politics. Ontological Security Studies (OSS) has expanded on this insight, emphasising that actors may prioritise maintaining a stable sense of self over physical security and other concerns. Yet the question of radical identity change, particularly its affective dimension, remains underexplored. To address this gap, we draw on Lacanian psychoanalysis and argue that ontological security is sustained by fantasies aimed at filling a primordial lack that can never be resolved. This lack generates anxiety, which actors attempt to soothe by attaching their desires to empirical signifiers – objects-cause of desire – that promise wholeness. Our argument centres on the idea that the rearticulation of desire occurs through the affective mechanism of catharsis, manifesting as either metaphor or metonymy. We illustrate our argument through the case of Serbia’s cathartic (re)articulation of Kosovo as its object-cause of desire. In particular, we juxtapose earlier successful articulations of Kosovo as a metaphoric substitution for other desires with more recent, less effective attempts to rearticulate the north of Kosovo and the submerged cultural heritage in Gazivode Lake as metonymic substitutions for the rest of the territory.
A new species of flatfish (Pleuronectiformes) is described from early Oligocene deposits of the Keasey Formation near Mist, Oregon, USA. The rare preservation of an articulated fish in the Mist crinoid lagerstätte is likely because the specimen represents a relatively pelagic immature individual that had not yet settled into the typical benthic lifestyle of adult flatfishes. The new species is included in a phylogenetic analysis; although it is lacking many characters, it is recovered as an early diverging lineage, sister to the extant members of the superfamily Pleuronectoidea. This phylogenetic position fits well with the age of this fossil and conforms with the origin of flatfishes occurring in the early Cenozoic, followed by diversification and radiation throughout the Eocene, Oligocene and Miocene epochs.
Compressible jets impinging on a perpendicular surface can produce high-intensity, discrete-frequency tones. The character of these tones is a function of nozzle shape, jet Mach number, impingement-plate geometry, and the distance between nozzle and plate. Though it has long been recognised that these tones are associated with a resonance cycle, the exact mechanism by which they are generated has remained a topic of some debate. In this work, we present evidence for a number of distinct tone-generation mechanisms, reconciling some of the different findings of prior authors. We demonstrate that the upstream-propagating waves that close resonance can be confined within the jet, or external to it. These waves can be either weak and relatively linear, or strong and nonlinear from their inception. The waves can undergo coalescence or merging, and in some configurations, pairs of waves rather than singletons appear. We discuss both historical and new evidence for multiple distinct processes by which upstream-propagating waves are produced: direct vortex sound, shock leakage, wall-jet-boundary fluctuations, and wall-jet shocklets. We link these various mechanisms to the disparate collection of upstream-propagating waves observed in the data. We also demonstrate that multiple mechanisms can be provoked by a single vortex, providing an explanation as to why sometimes pairs of waves or merging waves are observed. Through this body of work, we demonstrate that rather than being in opposition, the various pieces of past research on this topic were simply identifying different mechanisms that can support resonance.
By synthesising findings from both clinical and preclinical research, this review aims to provide an understanding of the interplay between 5-HT2A receptor psychedelics and the immune system and considers how their immunomodulatory effects associate with neuronal and behavioural changes.
Methods:
A PubMed literature search covering the past 30 years was conducted using keywords such as ‘5-HT2A receptor’, ‘psychedelics’, ‘immune system’, and ‘HPA axis’. Studies were included if they addressed the effects of 5-HT2AR psychedelics on immune function, neuroimmune interactions, or HPA axis involvement. This narrative review synthesises evidence highlighting the bi-directional effects of 5-HT2AR psychedelics between the immune and nervous systems, identified through this search process.
Results:
Preclinical and clinical studies report that 5-HT2AR psychedelics have some direct immunomodulatory properties with downregulation of gene regulators like NF-κB, and reduced cytokine expression such as TNF-α, IL-6, and IL-1β at a central and peripheral level, accompanied by modulation of corticotrophin releasing hormone (CRH), adrenocorticotrophic hormone (ACTH), and cortisol. Direct immunomodulatory effects are mediated by pathways involving serotonin receptors, the Sigma-1 receptor, and the TrkB receptor. Immunomodulation is further mediated indirectly via the HPA axis.
Conclusion:
Further studies will determine the molecular and cellular mechanisms underlying these immunomodulatory effects. There is growing interest in the potential of 5-HT2AR psychedelics for treating a range of mental health and brain disorders. In keeping with their immunomodulatory actions, the likely modulation of brain glia and glial-neuronal interaction remains to be determined, representing a promising direction of further research on the therapeutic potential of 5-HT2AR psychedelics.
We present a flexible, multilayer fabric strain sensor composed of a carbon fabric layer sandwiched between elastic bands. The sensor achieved a gauge factor of 3.4 and maintained its durability up to 635% strain. Its uniform graphite layer enabled reliable fabrication and easy integration into wearable formats. Performing well on commercial gloves and bands, the sensor effectively captured strain variations during body movement and enabled wireless transmission for real-time monitoring. Distinct resistance patterns were recorded for various body motions such as walking, jogging, jumping, and knee bending with a clear separation between high- and low-intensity activities. The overall design supports scalable fabrication and practical integration into wearable systems.
Schizophrenia is a severe and disabling psychiatric illness that profoundly affects a person’s ability to think clearly, perceive reality, manage emotions, and engage in daily activities. While antipsychotic medications have long been the cornerstone of treatment, debates persist around their long-term use and potential impacts on brain structure and function. In our review, we examine whether antipsychotic medications improve or worsen long-term outcomes in schizophrenia, particularly when treatment is refused or discontinued. Drawing from randomized controlled trials, large-scale observational studies, forensic outcome data, international guidelines, and neuroimaging research, the findings demonstrate that sustained antipsychotic treatment significantly reduces relapse, improves functional outcomes, and may protect against neurobiological deterioration. In contrast, untreated or inconsistently treated psychosis is associated with higher relapse rates, treatment resistance, cognitive decline, and progressive brain changes. While treatment must be personalized and compassionate, the cumulative evidence supports the critical role of early and continuous antipsychotic use in preserving health, autonomy, and long-term recovery for individuals living with schizophrenia.
Fall from height is common in all age groups. In 2020 alone, over 6000 people in Canada died from fall-related injuries. Most of the published literature investigating fall-related injuries are often focused on fracture patterns, survival and recovery. Fatal falls are not well studied. The objective of this study is to characterize the demographics and craniocerebral and vertebrospinal injury patterns related to fatal falls within Southwestern Ontario.
Methods:
A retrospective case review was conducted at the Department of Pathology, London Health Sciences Centre, for deaths attributed to falls from 2000 to 2020. Only cases with complete autopsy and detailed neuropathology reports were included. Demographic data, comorbidity profiles and craniocerebral and vertebrospinal injuries, along with scene details, were collected and analyzed.
Results:
45 cases were included, with a male sex predominance and a mean age of 60.3 ± 18.1 years. The most common head injuries were hematoma, cerebral contusions and skull base fractures. Falls from stairs were the most common. Low fall (<3 m) was associated with subfalcine herniation and was more commonly seen in older individuals (>65 years). Younger individuals were more prone to falls from a high height (>3 m), with frontotemporal lobe contusions as the most common finding.
Discussion:
This study provides a detailed depiction of craniocerebral and vertebrospinal injury patterns of the fatal falls in Southwestern Ontario. Our findings show low falls are a more common cause of fatalities in individuals 65 years and older, and age is a significant predictor of frontal contusions and subdural hematomas.
This research note examines the evolving nature of political parties in the contemporary era, with a particular focus on the trend of movementization, defined as the process by which political parties adopt organizational, strategic, and discursive elements of social movements to revitalize their declining structures and reconnect with society. While early studies on this phenomenon primarily focused on movement parties—challenger actors that positioned themselves at the intersection of institutional and contentious politics, blending conventional and unconventional repertoires of action—recent developments suggest that movementization is no longer confined to movement-parties only. Instead, it is becoming a broader trend affecting both challenger and mainstream parties across the entire ideological spectrum. This research note aims to review and critically assess the existing literature on movementization, identifying key theoretical and empirical contributions while highlighting unresolved questions and methodological gaps. Although substantial work has been done on individual case studies, the field remains fragmented and lacks systematic comparative analysis. To advance the study of movementization, this note calls for a shift from case-centric approaches toward comparative frameworks, integrating quantitative indicators and cross-national perspectives to better assess the prevalence, drivers, and consequences of this transformation. By doing so, it seeks to contribute to a more structured and generalizable understanding of how movementization is reshaping contemporary party politics.
This book began with a set of propositions about how the ancient Greek religious system worked, particularly in relation to divine manifestation. I set out to explore how technology featured and functioned with(in) those propositions which mediated between human and supernatural realms. Including the mechanical in the discourse on divine epiphany and religious experience is not intuitive. Karel Čapek’s satiric vision of a machine that creates practically free energy but spurts out a numinous by-product known as the Absolute is both very relevant and utterly alien to the ancient context. It is alien in that Čapek’s novel is focalised through (relatively) modern preconceptions of technology and religion as antithetical. The protagonist’s invention is strictly a machine of science fiction. That a sense of the numinous might be created by mechanical technology is entertained in the story as imaginatively (and metaphorically) compelling but remains impossible in practical terms.
This article argues that allegorical exegesis is important for understanding the writings of William of Malmesbury, both in his exegesis and beyond. In the mid-1130s, William penned a commentary on Lamentations in part to explain the causes and aftermath of the Norman Conquest. His allegorical exegesis decried exploitation and mismanagement of ecclesiastical lands by episcopal appointees from the continent, including his own bishop, Roger of Salisbury. In William’s sometimes veiled yet unmistakable critiques, Roger appears as an invading tyrant whose tenure as abbot of Malmesbury amounts to a period of Babylonian captivity for the monks of that house.
Four Palaearctic species of Staphylininae (Coleoptera: Staphylinidae) are reported from North America for the first time: Heterothops cognatus Sharp, H. praevius (Erichson), Philonthus chujoi Dvořák, and Quedius (Raphirus) maurorufus (Gravenhorst). We suspect that these species are part of a more recent cohort of accidental introductions to North America. Notably, two of them are native to the East Palaearctic, an unusual source of adventive staphylinids in North America because nearly all others are native to Central Europe. We suggest that the East Palaearctic is an underrecognised and increasingly important source for recently adventive soil invertebrates and that increased taxonomic focus on this fauna is important to North American biosecurity. The detection of trans-Palaearctic H. praevius resulted in the recognition of H. praevius Erichson (= H. marmotae Smetana syn. nov.). We also newly report the Nearctic species Heterothops conformis Smetana and H. sordidus Smetana from eastern North America. Philonthus debilis, a close relative of P. chujoi, is reported from the Yukon Territory, representing the northernmost locality known for this long-established adventive species. Illustrations of diagnostic features, barcode data, and distribution maps are provided for all four species. Updated or new identification keys are provided to aid in the recognition of these species in eastern North America.
The present article stresses the unmatched quality of late-medieval English manorial documents, both in quantity and quality, and their importance for both economic and environmental history. The corpus of manorial documents is used here as a case study to reinvigorate interest in late-medieval agricultural history of England. To do so, the paper suggests to integrate manorial documents with methods and data from other palaeo-scientific disciplines: palaeoclimatology, palaeoecology, aDNA analysis, stable isotope analysis, palaeo-epigenetics, and molecular analysis of parchments. The paper argues that involving scientists from these fields in collaborative work and integrating the novel analysis of manorial documents and palaeo-scientific data will both help resolve various outstanding controversies and reshape the discipline. But beyond that, such interdisciplinary interdisciplinary framework has a strong potential to ask and answer new questions, create new data knowledge, and take our knowledge to new heights.
Despite the burgeoning literature on historical humanitarianism and transnational history, little work has sought to explain the humanitarian intervention in the ‘first battleground’ of the Cold War, namely the Greek Civil War (1945–9). This paper casts light on the intricate relationship between civilians’ forced displacement and humanitarian aid during the late phases of this conflict. It also questions the extent to which humanitarianism was embedded into liberal and conservative politics of the early Cold War.
From 1941, multiple humanitarian organisations distributed aid to famine-stricken Greek areas, while the United Nations Relief and Rehabilitation Administration (UNRRA) intervened in Greece in 1943. As the civil strife intensified, more than 700,000 civilians were displaced during the royalist counterinsurgency operations against the communist rebels, while humanitarian groups received the mandate by the royalist government to feed, accommodate and rehabilitate these populations. Most of these relief workers had grappled with wartime famine and relied on the restoration of the pre-war political system to solidify their presence in Greece.
Drawing on archival material from UNRRA and the personal records of humanitarian workers Charles Schermerhorn and Ewan John Christian Hare, I scrutinise how humanitarian logistics became embedded into the conflict, and how the distribution or withholding, of aid determined the forced displacement of civilians. On a second level, I focus on the antagonism between the aid distributed by ‘purely’ humanitarian organisations, such as UNRRA, the NEF and the United Nations Children’s Fund (UNICEF), and the so-called ‘development’ aid, as institutionalised by the European Recovery Program in 1948.
Nakamura and Tsuji recently obtained an integral inequality involving a Laplace transform of even functions that implies, at the limit, the Blaschke-Santaló inequality in its functional form. Inspired by their method, based on the Fokker-Planck semi-group, we extend the inequality to non-even functions. We consider a well-chosen centering procedure by studying the infimum over translations in a double Laplace transform. This requires a new look on the existing methods and leads to several observations of independent interest on the geometry of the Laplace transform. Application to reverse hypercontractivity is also given.
