Non-adiabatic transitions in the near-UV photodissociation of H3+

Field: Physics and Astronomy (Physical Sciences)

Synopsis The near-UV photodissociation of H 3 + has been studied in a fast beam experiment. The kinetic energy release and branching ratio among the fragmentation channels were obtained by three-dimensional imaging of the dissociation products. It is found that the photodissociation of vibrationally excited H 3 + mostly produces vibrationally cold H 2 + and hot H 2 . The non-adiabatic repopulation of the ground potential energy surface after excitation is accounted for by modelling the wavepacket dynamics on the intersecting potential energy surfaces.

Perceptions of parents with children receiving special education support in the Stockholm and adjacent areas

Field: Social Sciences (Social Sciences)

This study had three objectives. One was to compare the needs, resources and supports perceived as available and needed by 32 parents of children with mild to moderate intellectual impairments, educated in self-contained special education classes (SCS), and 46 parents of children with general special needs educated in regular classes. A second objective was to compare these perceptions to the rated degree of pupil impairment. The third objective was to examine the applicability of two surveys. Results revealed that parents perceived strong informational needs regardless of educational setting, though the parents of children in the SCS group expressed stronger informational needs. Parents of children in the SCS group tended to be more satisfied with their relationship with schools than parents in the comparison group. Child impairments in the areas of social skills, behaviour, communication, and thinking and reasoning were highly correlated with parental needs and parental perception of school supports and resources. Factors influencing parental self-efficacy are discussed and recommendations are made for enhancing parental involvement in the child's education. Suggestions are also made for utilizing information derived from this study when planning the implementation of inclusive schools.
Combination of Molecule-Targeted Therapy and Photodynamic Therapy Using Nanoformulated Verteporfin for Effective Uveal Melanoma Treatment

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Uveal melanoma (UM) is the most common primary ocular malignancy in adults and has high mortality. Recurrence, metastasis, and therapeutic resistance are frequently observed in UM, but no beneficial systemic therapy is available, presenting an urgent need for developing effective therapeutic drugs. Verteporfin (VP) is a photosensitizer and a Yes-Associated Protein (YAP) inhibitor that has been used in clinical practice. However, VP's lack of tumor targetability, poor biocompatibility, and relatively low treatment efficacy hamper its application in UM management. Herein, we developed a biocompatible CD44-targeting hyaluronic acid nanoparticle (HANP) carrying VP (HANP/VP) to improve UM treatment efficacy. We found that HANP/VP showed a stronger inhibitory effect on cell proliferation than that of free VP in UM cells. Systemic delivery of HANP/VP led to targeted accumulation in the UM-tumor-bearing mouse model. Notably, HANP/VP mediated photodynamic therapy (PDT) significantly inhibited UM tumor growth after laser irradiation compared with no treatment or free VP treatment. Consistently, in HANP/VP treated tumors after laser irradiation, the tumor proliferation and YAP expression level were decreased, while the apoptotic tumor cell and CD8+ immune cell levels were elevated, contributing to effective tumor growth inhibition. Overall, the results of this preclinical study showed that HANP/VP is an effective nanomedicine for tumor treatment through PDT and inhibition of YAP in the UM tumor mouse model. Combining phototherapy and molecular-targeted therapy offers a promising approach for aggressive UM management.
EXPERIENCES OF SOCIAL PARTICIPATION AND PLACE AMONG OLDER ADULTS LIVING IN URBAN NEIGHBOURHOODS IN THE UK AND BRAZIL

Field: Social Sciences (Social Sciences)

Urban environments present opportunities and barriers in respect of social in/exclusion in old age. In response, policies and practices that support active ageing are increasingly being sought, central to which are the provision of opportunities for social participation. This paper presents qualitative data (including 180 face-to-face interviews, 120 walking interviews and 60 photo diaries), to examine experiences of social participation and place amongst older adults living across 6 cities and 18 neighbourhoods in the UK and Brazil. Thematic analysis identified key themes in relation to the urban environment and social participation: negotiating the built environment; place familiarity and control; place ownership and access; and security and safety. The findings support the integral role that urban environments play in shaping experiences of social participation in old age, identifying similarities and differences across case study areas. The paper offers suggestions for integrating social participation and place within age-friendly city frameworks.
Effects of virtual reality therapy on upper limb function after stroke and the role of neuroimaging as a predictor of a better response

Field: Medicine (Health Sciences)

ABSTRACT Background: Virtual reality therapy (VRT) is an interactive intervention that induces neuroplasticity. The aim was to evaluate the effects of VRT associated with conventional rehabilitation for an upper limb after stroke, and the neuroimaging predictors of a better response to VRT. Methods: Patients with stroke were selected, and clinical neurological, upper limb function, and quality of life were evaluated. Statistical analysis was performed using a linear model comparing pre- and post-VRT. Lesions were segmented in the post-stroke computed tomography. A voxel-based lesion-symptom mapping approach was used to investigate the relationship between the lesion and upper limb function. Results: Eighteen patients were studied (55.5 ± 13.9 years of age). Quality of life, functional independence, and dexterity of the upper limb showed improvement after VRT (p < 0.001). Neuroimaging analysis showed negative correlations between the internal capsule lesion and functional recovery. Conclusion: VRT showed benefits for patients with stroke, but when there was an internal capsule lesion, a worse response was observed.

Forecasting mortality rates of elderly in Indonesia using the first generalized Cairns-Blake-Dowd model

Field: Decision Sciences (Social Sciences)

The insurance companies in Indonesia is always aware of the importance of forecasting future mortality rates. If information about mortality rates for several future periods can be obtained in the present time, then the financial planning and policy in determining the amount of premium are expected to be better and more directed. This paper proposed the First Generalized Cairns-Blake-Dowd (CBD) model to forecast the mortality rates of the Indonesian population. The CBD model contains time series parameters. The first stage is to use the Least Square and Newton-Raphson methods to estimate these parameters. The accuracy of the estimation results is verified by the Mean Squared Error (MSE) value. The second stage is to use Holt's linear trend method to forecast the values of estimated parameters aims to calculate the future mortality rates. The level of forecasting accuracy is verified by Mean Absolute Percentage Error (MAPE) value. The MSE and MAPE for each age group are less than 10−4 and 5%, respectively. The forecasted mortality rates for the next periods are presented in the tabular and graphical form. The trend of the projected mortality rate shows a downward trend for each age group.

A comparative study on single event irradiation effects between Trench MOSFET and Split-gate-trench MOSFET

Field: Engineering (Physical Sciences)

The single event effects of conventional Trench MOSFET (T-MOS) and Split-gate-trench MOSFET (SGT-MOS) with the same breakdown voltage are compared in this paper by simulation. It is shown that the sensitive positions and failure process of single event burnout (SEB) and single event gate rupture (SEGR) are different for T-MOS and SGT-MOS. Compared with T-MOS, SGT-MOS has better anti single event effect ability.
The effects of sildenafil citrate on intrauterine growth restriction: a systematic review and meta-analysis

Field: Medicine (Health Sciences)

Abstract Background An increase in vascular resistance of uterine vessels is associated with intrauterine growth restriction (IUGR). Sildenafil citrate, a phosphodiesterase-5 inhibitor that stabilizes cyclic guanosine monophosphate (cGMP) and increases nitric oxide levels, improves placental perfusion by dilation of spiral arteries and is beneficial in managing IUGR. This study aims to determine the effectiveness of sildenafil citrate in improving perinatal outcomes in IUGR pregnancies. Methods Meta-analysis was performed on data extracted from all studies specific to sildenafil citrate in IUGR management, searching relevant articles on PubMed, Medline, Google Scholar, Embase, and Cochrane databases. Publications identified by the manual search, based on references in reviews, were also included. Dichotomous results were presented as risk ratio (95% confidence interval), while continuous results were expressed as mean difference (MD); samples represented by the random effects model. Results Nine trials were included where the sildenafil citrate effect was compared with a placebo or no intervention. A significant increase in birth weight [SMD (95% CI), 0.69 (0.31, 1.07)] was seen in IUGR pregnancies managed with sildenafil. However, gestational age (SMD (95% CI), 0.44 (-0.05, 0.94], fetal death rate [RR (95% CI), 0.56 (0.17, 1.79)] in IUGR pregnancies was not changed by sildenafil. Neonatal death [RR (95% CI), 0.93 (0.47, 1.86)] and neonatal intensive care unit (NICU) admissions [RR (95% CI), 0.76 (0.50, 1.17)] were not significantly different between sildenafil and control groups. Conclusion Sildenafil citrate increases birth weight and prolonged pregnancies but did not affect stillbirth rate, neonatal death, and NICU admission. Trial registration The study was registered in PROSPERO on September 18, 2021 (CRD42021271992).

The Relative Success of Africanized and European Honey-Bees Over a Range of Life-Zones in Costa Rica

Field: Agricultural and Biological Sciences (Life Sciences)

1. The reproductive success and biology of Africanized and European honey-bees (Apis mellifera) were compared for a year over three life-zones from 900 m to 2800 m in Costa Rica, with the aim of identifying the factors which might limit the distribution of both bee types in tropical highlands. ' 2. Determinations of colony success and comparative biology included survivorship during the rainy season, causes of colony mortality, frequency of swarming, absconding, seasonal patterns of weight gain, brood-rearing (worker and drone), and nectar and pollen storage. 3. There was a significant difference in survivorship during the rainy season between European colonies given supplemental feedings and those not so fed; however, there were no significant differences in survivorship between the fed and unfed Africanized colonies. 4. More European than Africanized colonies died from gradual weakening, and only Africanized colonies absconded. However, colony deaths and absconding occurred with approximately equal frequency over all elevations during the year. 5. Almost three times as many Africanized as European colonies swarmed over the year. Although the majority of swarms occurred in the dry season at the lowest apiary, both bee types issued swarms at the highest elevation. 6. Africanized colonies weighed significantly more and maintained significantly larger worker brood areas than European colonies across all elevations for most months of the year, except at 2800 m from March through June. 7. Africanized colonies reared more drones than European colonies, except during the dry season at the highest elevation. 8. There were no significant differences in pollen storage between bee types across all elevations for 10 months of the year, and there were no significant differences in nectar storage throughout the year. 9. The most pronounced differences between the bee types were observed in the lowlands, which accounts for the rapid population growth and range expansion of Africanized bees, and their displacement of European bees in these areas. 10. The differences between the bee types in the highlands (2200 m and 2800 m) were not as pronounced for any of the determinations, indicating that neither was better adapted than the other to the climatic and resource conditions of tropical highlands. Possible reasons for the similarities in survival and performance between the bee types in the highlands as well as the implications of these findings on the potential distribution of Africanized bees are discussed.
Wnt1 Accelerates anEx VivoExpansion of Human Cord Blood CD34+CD38−Cells

Field: Medicine (Health Sciences)

Cord blood hematopoietic stem cells (CB-HSCs) transplantation has been increasing gradually with facing the limitation of insufficient quantity of HSCs in each CB unit. Therefore, efficient expansion methods which can maintain stem cell characteristics are needed. In this study, umbilical CB-CD34 + cells were cultured in two different cytokine cocktails: 4 factors (4F = Flt3-L, SCF, IL-6, and TPO) and 5 factors (5F = Wnt1 + 4F) in both serum and serum-free media. The data revealed that the best condition to accelerate an expansion of CD34 + CD38 − cells was serum-free culture condition supplemented with 5F (5F KSR). This condition yielded 24.3 ± 2.1 folds increase of CD34 + CD38 − cells. The expanded cells exhibited CD34 + CD38 − CD133 + CD71 low CD33 low CD3 − CD19 − markers, expressed nanog, oct3/4, c-myc, and sox2 genes, and maintained differentiation potential into lymphoid, erythroid and myeloid lineages. The achievement of CD34 + CD38 − cells expansion may overcome an insufficient quantity of the cells leading to the improvement of the stem cell transplantation. Altogether, our findings highlight the role of Wnt1 and the new culture condition in stimulating hematopoietic stem/progenitor cells expansion which may offer a new therapeutic avenue for cord blood transplantation, regenerative medicine, stem cell bank applications, and other clinical applications in the future.
Unsupervised Domain Adaptation via Structurally Regularized Deep Clustering

Field: Computer Science (Physical Sciences)

Unsupervised domain adaptation (UDA) is to make predictions for unlabeled data on a target domain, given labeled data on a source domain whose distribution shifts from the target one. Mainstream UDA methods learn aligned features between the two domains, such that a classifier trained on the source features can be readily applied to the target ones. However, such a transferring strategy has a potential risk of damaging the intrinsic discrimination of target data. To alleviate this risk, we are motivated by the assumption of structural domain similarity, and propose to directly uncover the intrinsic target discrimination via discriminative clustering of target data. We constrain the clustering solutions using structural source regularization that hinges on our assumed structural domain similarity. Technically, we use a flexible framework of deep network based discriminative clustering that minimizes the KL divergence between predictive label distribution of the network and an introduced auxiliary one; replacing the auxiliary distribution with that formed by ground-truth labels of source data implements the structural source regularization via a simple strategy of joint network training. We term our proposed method as Structurally Regularized Deep Clustering (SRDC), where we also enhance target discrimination with clustering of intermediate network features, and enhance structural regularization with soft selection of less divergent source examples. Careful ablation studies show the efficacy of our proposed SRDC. Notably, with no explicit domain alignment, SRDC outperforms all existing methods on three UDA benchmarks.
