Effects of early maternal separation on the expression levels of hippocampal and prefrontal cortex genes and pathways in lactating piglets

Introduction In actual production, due to increased litter size when raising pigs, the management of piglets by split-suckling leads to intermittent neonatal maternal separation (MS). Early lactation is a critical period for the cognitive development of the brain of newborn piglets, and we hypothesized that intermittent MS may affect piglets’ neurodevelopment and cognitive ability. Methods To determine the effects of the MS, we selected hippocampal and prefrontal cortex (PFC) tissues from piglets for the detection of neurodevelopmental or cognitive related indicators, the control group (Con group, n = 6) was established with no MS and an experimental group (MS group, n = 6) was established with MS for 6 h/day. Piglets in the MS group were milk-supplemented during the separation period and all piglets in both treatment groups were weaned at postnatal day (PND) 35. On PND 35, three male piglets from each group were sacrificed for hippocampus and PFC samples used for reference transcriptome sequencing. Following bioinformatics analysis, Gene ontology (GO) enrichment, Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis, and candidate gene screening and pathway were performed for differentially expressed genes. Results The results showed that a total of 1,632 differential genes were identified in the hippocampus of the MS group, including 1,077 up-regulated differential genes, 555 down-regulated differential genes, and 655 significant GO entries. Analysis of the PFC of the MS group revealed 349 up-regulated genes, 151 down-regulated differential genes, and 584 significant GO entries. Genes associated with neurodevelopment were screened for large fold differences in the hippocampus, and genes associated with cognition were screened for large fold differences in the PFC. Quantitative real-time PCR (qRT-PCR) was used to verify the sequencing data. Western blot (WB) experiments revealed that MS inhibited the neurodevelopment-related WNT signaling pathway in the hippocampus and the cognitive-related PI3K-AKT signaling pathway in the PFC. Discussion Taken together, these findings suggest that intermittent MS may affect some cognitive functions in piglets by damaging hippocampal and PFC genes or pathways.
Evidence for Extrusive Mg‐Suite Magmatism on the Moon? Fine‐Grained Magnesian Clasts in an Apollo 16 Impact Melt Breccia

The magnesian suite (Mg‐suite) of rocks record some of the earliest intrusive magmatism on the Moon. Studies of these Mg‐suite rocks find they are plutonic or hypabyssal, formed typically kilometers under the lunar surface. Several models exist to explain the formation and evolution of the Mg‐suite but distinguishing between hypotheses can be difficult given the limited sample availability. The global extent of Mg‐suite magmatism remains in debate and is key to constraining models of early secondary crust building. In this study, we present magnesian clasts within Apollo impact melt rock 68815. These clasts contain olivine, plagioclase, with minor amounts of Mg‐Al‐spinel and pyroxene similar to spinel troctolites of the Mg‐suite, but they lack plutonic textures. We provide evidence that some of the clasts may be of extrusive volcanic origin akin to terrestrial komatiites while others might represent crystalline impact melts. There exists a large breadth of evidence for Mg‐suite intrusives, whereas here, we present possible evidence of Mg‐rich volcanic counterparts. If valid, this would broaden the known diversity of lunar volcanism during the initial stages of secondary crust building. We anticipate this finding to provide a greater constraint onto models of Mg‐suite ascent and emplacement, which only currently consider intrusive magmatism, as well as renewed motivation to examine impact melt breccias for rare and understudied lithologies. Future trace element studies or radiometric dating could be used to further interrogate the connections of these clasts to the Mg‐suite.
What does the audience care? The effects of travel vlog information quality on travel intention

Although travel vlogs have recently been adopted as digital marketing tools to promote tourist spots, relatively little is known about which attributes of travel vlogs and how these attributes motivate audiences to travel. This study emphasizes the importance of information conveyed by the content of travel vlogs and aims to explore how the information quality (information usefulness, ease of use, and comprehensiveness) in travel vlogs affects audience travel intention through presence, enjoyment, and flow experience. The partial least squares structural equation modeling (PLS-SEM) is adopted to analyze data collected from 241 respondents who had experience with watching travel vlogs. The results indicate that the three facets of information quality positively influence travel intention through the mediating role of presence, enjoyment, and flow experience. The total effect of information comprehensiveness on travel intention is the strongest, followed by information usefulness and ease of use orderly. The findings extend the literature on travel vlogs by validating the role of information quality in travel vlogs. In line with this, travel vlog creators are suggested to pay attention to information management when making vlogs.
Finite-Time Stabilization for Fuzzy Complex-Valued Neural Networks With Mixed Delays via Comparison Approach

This article explores deeply the finite-time stabilization for the fuzzy complex-valued neural networks (CVNNs) model with discrete delays and distributed delays. Based on the quadratic norm and one norm in complex domain, we construct the appropriate comparison functions and design the controllers without the delay information. Then, we establish algebraic criteria to guarantee finite-time stabilization for fuzzy CVNNs with multiple time delays by exploiting the comparison approach and inequality techniques. Different from applying the finite-time stability theorem to deal with finite-time control problems of delayed systems, we combine the comparison strategy with the nonseparation method, which provides a cornerstone to analyze the finite-time control of complex-valued systems with time delays. Finally, numerical simulations are conducted to testify the availability of theoretical researches.
Dynamics of Ice-Island Motion Near the Coast of Axel Heiberg Island, Canadian High Arctic

The largest ice island presently known to exist in the Arctic Ocean has a mass of about 700 × 106 tonnes, an area of about 26 km2, and a mean thickness of 42.5 m. Known as Hobson’s Ice Island, this large ice feature has been tracked almost continuously since August 1983 with a succession of Argos buoys. In this paper, two particular ice-island movement episodes near the north-west coast of Axel Heiberg Island are described: 6–16 May 1986 and 14–21 June 1986. Each movement episode is analyzed in terms of the forces acting on the ice island, including wind shear, water drag, water shear, Coriolis force, sea-surface tilt, and pack-ice force. Ice-island movement is generally preceded by an offshore surface wind, and a threshold wind speed of 6 m s°1 appears to be necessary to initiate ice-island motion. An angle of 50° between surface wind and ice-island movement direction is noted during one episode. The pack-ice force, which appears to be the dominant arresting factor of ice-island motion for these two episodes, varies from 100° to 180° to the left of the ice-island velocity direction, depending upon whether the ice island is accelerating or decelerating.
A Least Squares Approach for Estimating Non-linearity Parameters for OFDM Signals with Bussgang Receivers

Non-linear distortion imposed to orthogonal frequency division multiplexing (OFDM) signals from non-linear power amplifiers (PAs), has always been a challenging problem in wireless communications. This is due to the high peak-to-average power ratio (PAPR) of OFDM signals. To overcome this issue, receiver side compensation techniques based on distortion cancellation and iterative detection have been proposed. However, these techniques require knowledge of the non-linearity (NL) parameters. Therefore, in this paper we focus on NL parameter estimation and propose a least squares (LS) based estimation technique by transmitting a training signal. We study the performance of the proposed technique for the solid state power amplifier (SSPA) model and the Bussgang model. The studies are done considering both perfect channel knowledge and imperfect channel knowledge at the receiver. The results show that the proposed technique has good accuracy and performance for distortion cancellation and iterative detection based receivers such as the Bussgang receiver. The results also indicate that the estimation technique is more sensitive to channel estimation error than the additive Gaussian noise.
Teachers’ Perceptions Toward Video as a Tool for Feedback on Students’ Oral Performance

Video technology has the potential to improve opportunities for students to benefit from feedback that is essential for learning. However, previous studies have all dealt with videos of tutors, rather than videos of students’ performances. This study explores whether video technology contributes to the quality of feedback on students’ oral language performance and investigates how language teachers perceive contemporary technology regarding student education. Participants in the study were eight incumbent teachers involved in language education. The interview data suggested that the teachers seemed to be very positive about using video technology as a tool for feedback. The technology not only allowed for evidence-based accounts which served to enrich the quality of feedback, but also enabled them to highlight specific aspects of oral performances and create feedback that is conducive to understanding. The findings of this study showed that technology-enhanced evidence-based feedback will be able to provide an important supplement to written feedback, adding one more mode for an effective feedback process.
Bearing-Only Formation Tracking Control of Multiagent Systems

This paper studies the problem of bearing-only formation control of multiagent systems, where the control of each agent merely relies on the relative bearings to its neighbors. Although this problem has received increasing research attention recently, it is still unsolved to a large extent due to its highly nonlinear dynamics. In particular, the existing control approaches are only able to solve the simplest scenario where the target formation is stationary and each agent is modeled as a single integrator. The main contribution of this paper is to propose new bearing-only formation control laws to 1) track moving target formations and 2) handle a variety of agent models including single-integrator, double-integrator, and unicycle models. These control laws are an important step towards the application of bearing-only formation control in practical tasks. Both numerical simulation and real experimental results are presented to verify the effectiveness of the theoretical results.
PAPER for Plastic Debris Rivers to the Sea Conference 2005 Seabirds as indicators of plastic pollution in the North Pacific

As far-ranging top predators, seabirds are valuable biological indicators of climatic and human-related perturbations of marine food webs because they sample marine ecosystems over large space and time scales. These same ecological reasons make seabirds valuable indicators of plastic pollution in coastal and oceanic waters. In this paper we review studies of the incidence and impacts of plastic ingestion on North Pacific seabirds, and identify several ecological factors that influence the susceptibility of different species. Foraging mode, habitat use, and body size are important factors to consider when quantifying the magnitude of plastic ingestion and its potential impacts on seabird populations. Largebodied, oceanic species that feed opportunistically at the surface are most susceptible to plastic ingestion. In particular, far-ranging tubenose (Procellariiformes) species, like fulmars and albatrosses, are ideal bio-indicators of marine plastic pollution. In this paper we report on plastic ingestion by Northern Fulmars (Fulmarus glacialis) collected in California during 2003–2004, and review past research on far-ranging Hawaiian albatrosses. These results underscore the value of studies of seabird diet and stomach contents to monitor trends in North Pacific marine pollution. Although it is difficult to quantify population-level impacts resulting from the documented patterns of plastic ingestion in seabirds, the incidence of plastic debris in many long-lived North Pacific species is an emerging ecological problem that warrants further investigation. The mitigation of plastic ingestion in seabirds is a complex problem that will require broad-reaching cooperation between industry and wildlife resource managers, as well as education and public outreach. We present an educational program, designed to increase public awareness of the threats posed to seabirds by marine pollution, and to promote public stewardship of North Pacific seabirds.

This study aims to examine the phenomenon of alleged greenwashing at PT Tirta Fresindo Jaya as the producer of Le Minerale bottled water with variables recommended in several previous studies, including Greenwashing, Skepticism, Confusion, Information and Knowledge, and Green Purchase Intention. The population in this research were the people of Central Java who know Le Minerale's disposable gallon products. The sample in this research was 233 respondents who were taken using a purpose random sampling method. Results of research conducted using Structural Equation Modeling (SEM) processed with AMOS software, it shows that: (1) Greenwashing has a significant positive effect on skepticism. (2) Greenwashing has a significant positive effect on Confusion. (3) Skepticism has no effect on green purchase intention. (4) Confusion has no effect on green purchase intention. (5) Skepticism does not mediate the effect of greenwashing on the green purchase intention. (6) Confusion does not mediate the effect of greenwashing on the green purchase intention. (7) Information and knowledge do not moderate the relationship of confusion to the green purchase intention.
Past, Current, and Future Perspectives on Transplanting Acute Kidney Injury Kidneys

(1) Background: Acute kidney injury (AKI) kidneys have high non-utilization rates due to concerns regarding unfavorable outcomes. In this paper, we aimed to review the past, present, and future opinions on AKI kidneys. (2) Methods: A PubMed search was conducted for topics relevant to AKI kidney transplantation. (3) Results: Current short- and long-term data on AKI kidneys have demonstrated good outcomes including favorable graft function and survival. The role of procurement biopsies is controversial, but they have been shown to be beneficial in AKI kidneys by allowing clinicians to differentiate between reversible tubular injury and irreversible cortical necrosis. Machine perfusion has also been applied to AKI kidneys and has been shown to reduce delayed graft function (DGF). The incidence of DGF increases with AKI severity and its management can be challenging. Strategies employed to counteract this have included early initiation of dialysis after kidney transplantation, early targeting of adequate immunosuppression levels to minimize rejection risk, and establishment of outpatient dialysis. (4) Conclusions: Despite good outcomes, there continue to be barriers that impact AKI kidney utilization. Successful strategies have included use of procurement biopsies or machine perfusion and expectant management of DGF. With increasing experience, better use of AKI kidneys can result in additional opportunities to expand the donor pool.
Effects of perceived gender on the perceived social function of laughter

Previously, the sex of the speaker has been found to play an important role in how we perceive human and artificial voices. It was found, for example, that sex mediates in how we perceive the social function of laughter. We, however, are interested in how socially-formed concepts of gender influence how laugh-ter is perceived. To investigate this, we carried out a within-subjects study of listeners who judged social functions of the same laugh stimulus twice, which was framed as produced by either a man or woman. Mixed-effects ordinal regression modelling showed no statistically significant relations between the perceived gender of a laugh and its perceived social functions
Dynamique de population d'une légumineuse du sous-bois de la forêt landaise (Ulex europaeus) dans le cadre de la sylviculture du pin maritime : proposition d'un modèle conceptuel

La fixation symbiotique d'azote par l'ajonc d'Europe (Ulex europaeus) represente une source importante d'azote dans la foret cultivee de pins maritimes des 'Landes de Gascogne'. Cette these a pour objectif la creation d'un modele conceptuel de dynamique de population de l'ajonc dans la region en vue de la prediction du flux d'azote associe. Pour cela plusieurs etapes du cycle de vie de l'espece ont ete etudiees: la production et la predation des graines, puis le recrutement de nouveaux individus depuis le stock de graines du sol. Nos resultats suggerent que le maintien de cette espece heliophile a l'ombre de la canopee des pins est facilite par la diminution de l'allocation de ressources a la reproduction, lui permettant de maintenir sa croissance, et par la diminution de la predation des graines. Par ailleurs, le recrutement de nouveaux ajoncs semble influence par des facteurs ecologiques identifiables (e.g. humidite du sol). Mais ces facteurs sont fortement variables dans l'espace et dans le temps, et aucun micro habitat n'apparait comme plus favorable a la regeneration de l'espece. Ces resultats sont integres a un modele conceptuel, representant les differentes etapes du cycle de vie de l'espece, et l'impact des operations sylvicoles sur ces etapes. Les connaissances issues de cette these pourraient aussi beneficier a d'autres problematiques liees a l'espece (e.g. c'est une espece invasive dans de nombreuses regions du monde) et a la comprehension de l'ecologie de la regeneration des especes ligneuses. En effet, l'allocation des ressources a la reproduction pourrait etre plastique et permettre une reponse adaptative a un environnement changeant; et la variabilite spatiotemporelle de la regeneration des ligneux pourrait reposer sur l'existence de niches ecologiques de regeneration definies dans l'espace ecologique.
Bring Your Own Positioning System: An Infrastructure-free and Omnidirectional UWB-based Localization Approach

Wireless ad-hoc localization can play an enabling role for many safety-critical applications and help to save life. For instance, in challenging applications such as firefighting, first responders are often faced with the decision to enter a structure with limited to no visibility and lacking detailed information on the existing conditions. Relative position uncertainty or loss of contact may lower the operation's prospect of success or, in the worst case, result in human harm. This work aims to provide a novel ad-hoc localization system that allows for omnidirectional awareness of co-responders' locations, even under zero-visibility and non-line-of-sight conditions. To this end, we propose a novel ultra-wideband-based localization method combining multiple phase-difference of arrival capable nodes for accurate direction and distance estimation. A tightly integrated hardware setup enables time difference of arrival direction finding, augmenting the limitations of pure phase-based direction estimation. Additionally, single-sided two-way ranging is utilized for ad-hoc distance estimation. We have evaluated the localization performance for different realistic indoor scenarios under line-of-sight and non-line-of-sight conditions. Experimental results show an average 95th percentile 2D accuracy of 40 cm at a distance of up to 6 m in an unobstructed environment. In more challenging conditions which incorporate obstruction an accuracy of 1.2 m at up to 12 m distance could be achieved.
Caregiver Quality of Life: Satisfaction and Burnout

Informal caregivers (ICs) of cancer patients play a crucial role in health care. Several of the challenges they face can affect their quality of life (QoL). This cross-sectional study explored role of burnout and caregiving satisfaction in their relationship to QoL. Portuguese ICs of adult cancer patients (N = 92) answered a sociodemographic and caregiving questionnaire, the WHOQOL-SRPB BREF, assessing physical, psychological, social, environmental, and spiritual QoL domains; the Maslach Burnout Interview, assessing the dimensions of depersonalization, emotional exhaustion, and personal accomplishment; and a Visual Analogic Scale on caregiving satisfaction. We tested correlations and a parallel mediation model for each domain of QoL, considering burnout dimensions as possible mediators between satisfaction and QoL domains. Our results show that satisfaction, burnout dimensions, and almost all QoL domains are correlated. Together, burnout dimensions seem to mediate the relationship between caregiving satisfaction and psychological, environmental, and spiritual QoL. Satisfaction had a significant indirect effect solely through emotional exhaustion on psychological QoL (β = 1.615, 95% BCI [0.590; 2.849]), environmental QoL (β = 0.904, 95% BCI [0.164; 1.876]), and spiritual QoL (β = 0.816, 95% BCI [0.019; 1.792]). It seems essential for mental health professionals to address these dimensions when providing support to an IC.
An Improved End-to-End Audio-Visual Speech Recognition Model

By incorporating lip language, audio-visual speech recognition can effectively improve the recognition effect in noisy environments, and will slightly improve the recognition effect in quiet environments. we use a frequency domain attention based residual network (Fca-Net) as the model of the vision front-end module, which extracts more features that are helpful to the AVSR and VSR system at a small cost. And use the powerful speech pre-training model Hu-BERT as the recognition front-end model of ASR. We compare the impact of different model as visual back-end modules and fusion modules on the AVSR system. Our experiments show that the model selection of the fusion module is critical to the performance of the AVSR sys-tem. Ultimately, our proposed model achieves state-of-the-art results on audio-visual speech recognition tasks using the LRS2 dataset.
Unreliable retrial queueing system with working vacation

This paper investigates an unreliable $ M/G(P_{1}, P_{2})/1 $ retrial queueing system with a woking vacation. An arriving customer successfully starts the first phase service with the probability $ \alpha $ or the server fails with the probability $ \bar{\alpha} $. Once failure happens, the serving customer is taken to the orbit. The failed server is taken for repair with some delay. Once the repair is comleted, the server is ready to provide service once again. In this background, we implemented the working vacation scenario. During working vacation, the service will be provided at a slower rate, rather than entirely stopping the service. The supplementary variable method was adopted to find the orbit and system lengths. Additionally, some unique results and numerical evaluations have been presented.
