description: Nigeria has continued to face separatist agitations over time with dire consequences. This study examined the fallout of these ethnic agitations on economic development in South East Nigeria. The specific objectives of the study included determining the effect of ethnic agitations on foreign direct investment in South East, Nigeria; ascertaining the impact of ethnic agitations on the level of infrastructural development in South East, Nigeria; and examining the impact of ethnic agitations on human capital flight in South East Nigeria. The study chose three states Enugu, Abia, and Imo with a population of 11,641,017. The sample size obtained through Taro Yamani's statistical formula was 400. The study employed a descriptive survey design. The data were analyzed through the use of mean score while the Chi-square test technique was applied in the test of hypotheses. The findings showed that ethnic agitations have a significant effect on foreign direct investment in South East, Nigeria; it was discovered that ethnic agitations do have a significant effect on the level of infrastructural development in South East, Nigeria; and that the result indicated that ethnic agitations have a significant effect on human capital flight in South East Nigeria. The study concluded that the impact of ethnic agitations on the economic development of South East Nigeria is substantial. Ethnic tensions create an environment of uncertainty and instability, deterring foreign direct investment, hindering infrastructural development, and driving human capital flight from the region. The study recommended among others that to attract foreign direct investment (FDI) and other development strides, the government should inculcate fairness, justice, and equity into our political and administrative system to promote peace and stability, reassure investors, and create a conducive environment in the South East region, thereby fostering economic growth

description: According to the latest WHO data, over 26 million women, mostly of late reproductive and perimenopausal periods (35-55 y.o.) are diagnosed with uterine leiomyoma (UL) [1]. According to recent publications, the key risk factors for UL may be diabetes mellitus (DM), obesity, hypertension, or a combination of these as part of metabolic syndrome (MS) [2]. Risk factors for MS are hypertension, dyslipidemia, fasting hyperglycemia, and central obesity [3,4]. The aim of the research is to present a clinical case of combined gynecological and vascular pathology on the background of severe extragenital diseases (DM type II, obesity, essential hypertension), conducted at the Kyiv Regional Clinical Hospital (KRCH) as the clinical base of the Department of Obstetrics and Gynecology №1 Shupik NHUU.

description: The combination of chain-mapping and tensor-network techniques provides a powerful tool for the numerically exact simulation of open quantum systems interacting with structured environments. However, these methods suffer from a quadratic scaling with the physical simulation time, and therefore they become challenging in the presence of multiple environments. This is particularly true when fermionic environments, well-known to be highly correlated, are considered. In this work we first illustrate how a thermo-chemical modulation of the spectral density allows replacing the original fermionic environments with equivalent, but simpler, ones. Moreover, we show how this procedure reduces the number of chains needed to model multiple environments. We then provide a derivation of the fermionic Markovian closure construction, consisting of a small collection of damped fermionic modes undergoing a Lindblad-type dynamics and mimicking a continuum of bath modes. We describe, in particular, how the use of the Markovian closure allows for a polynomial reduction of the time complexity of chain-mapping based algorithms when long-time dynamics are needed.

description: Originally applied on domestic and lab animals, assisted reproduction technologies (ARTs) have also found application in conservation breeding programs, where they can make the genetic management of populations more efficient, and increase the number of individuals per generation. However, their application in wildlife conservation opens up new ethical scenarios that have not yet been fully explored. This study presents a frame for the ethical analysis of the application of ART procedures in conservation based on the Ethical Matrix (EM), and discusses a specific case study—ovum pick-up (OPU) procedures performed in the current conservation efforts for the northern white rhinoceros (Ceratotherium simum cottoni)—providing a template for the assessment of ART procedures in projects involving other endangered species.

description: Liver cirrhosis, known to increase intra- and postoperative complications after hepatic resection, has always been considered a limiting factor by the liver surgeon. We analyzed the effect of hepatic inflow occlusion in minimally invasive liver resection in patients with HCC and cirrhosis, and found no increase in complications or liver failure. While clinical studies like these need to accompany the development of new surgical techniques to re-evaluate risks for individual patient groups, and keep cirrhotic patients from being excluded from optimal treatments, it is also crucial to better understand the underlying mechanisms regulating inflammation, fibrosis and cirrhosis. Chronic inflammation of the gut or the liver can result in fibrosis and increased risk of cancer. Inflammation and its resolution are finely regulated by a multitude of interconnected signaling pathways, including purinergic signaling by extracellular nucleotides and nucleosides. Extracellular ATP is known as a pro-inflammatory “danger signal” and adenosine as an immunoregulatory and pro-regenerative stimulus. The balance between ATP and adenosine is regulated by a group of cell-surface localized enzymes, ecto-nucleotide triphosphate diphosphohydrolases (ENTPD). CD39 (ENTPD1) is located on immune cells and leads to their immunoregulatory differentiation. ENTPD2 and 3 are similar enzymes that are expressed on portal fibroblasts and pericytes, and on endocrine and exocrine tissues, respectively. In the presented research project, different experimental models of acute and chronic, intestinal and hepatic inflammation were performed using mice with global or targeted deficiency for CD39, ENTPD2 or ENTPD3. These studies confirmed the central role that these ecto-enzymes play as a “switch” turning a local micro-milieu into an immunoregulatory environment. Macrophage-expressed CD39 was found to alleviate sclerosing cholangitis and biliary fibrosis. ENTPD2, while not affecting liver regeneration after partial hepatectomy, attenuates acute necrotic liver injury and liver fibrosis. ENTPD2 and, to a lesser extent ENTPD3 have protective properties in experimental colitis, most likely due to their expression on the enteric nervous system. Taken together, these findings expose the crucial role that CD39 and other ENTPD play through modulating purinergic signaling in creating an immunoregulatory microenvironment in gut and liver. These insights contribute to a better understanding of inflammation and anti-inflammatory medication in autoimmune diseases of liver and intestine.
Understanding the Dependence of Perception Model Competency on Regions in an Image

description: While deep neural network (DNN)-based perception models are useful for many applications, these models are black boxes and their outputs are not yet well understood. To confidently enable a real-world, decision-making system to utilize such a perception model without human intervention, we must enable the system to reason about the perception model's level of competency and respond appropriately when the model is incompetent. In order for the system to make an intelligent decision about the appropriate action when the model is incompetent, it would be useful for the system to understand why the model is incompetent. We explore five novel methods for identifying regions in the input image contributing to low model competency, which we refer to as image cropping, segment masking, pixel perturbation, competency gradients, and reconstruction loss. We assess the ability of these five methods to identify unfamiliar objects, recognize regions associated with unseen classes, and identify unexplored areas in an environment. We find that the competency gradients and reconstruction loss methods show great promise in identifying regions associated with low model competency, particularly when aspects of the image that are unfamiliar to the perception model are causing this reduction in competency. Both of these methods boast low computation times and high levels of accuracy in detecting image regions that are unfamiliar to the model, allowing them to provide potential utility in decision-making pipelines. The code for reproducing our methods and results is available on GitHub: https://github.com/sarapohland/explainable-competency.

description: Актуальність теми. До пізніх ускладнень цукрового дібету (ЦД) відноситься синдром дібетичної стопи (СДС). На фоні гіперглікемії та ураженні нервів, судин при розвитку СДС розвиваються некротичні, деструктивні та дегенеративні процеси в м`яких тканинах, кістках та суглобах. [1]. СДС спостерігається більше ніж у 20 – 50 % пацієнтів з цукровим діабетом і є однією з вагомих причин виконання нетравматичних ампутацій нижніх кінцівок. [2] По даним авторів виконується до 30 % ампутацій другої нижньої кінцівки у пацієнтів яким на протязі трьох років було вконано ампутацію першої нижньої кінцівки з приводу СДС, до 50 % пацієнтам виконують ампутацію іншої нижньої кінцівки на протязі 5 – ти років. [3] В перший рік після ампутацій смертність становить 13 – 40 %, в наступні 5 років становить 39 – 80 %. [4] Ураження кінцівок при ЦД наносять вагомі соціально – економічні збитки. Приблизно 10% бюджетів охорони здоров`я у різних країнах виділяють на лікування та профілактику СДС, що становить від 4,6 до 13,7 млрд доларів. [5,6] Середня тривалість госпіталізації хворих з гнійно – некротичними ураженнями при ЦД приблизно 86 – 91 день, що на 47 % перевищує тривалість госпіталізації при інших ускладнення ЦД. Тому питання з приводу лікування та надання соціальної допомоги не можна вважати закритим, що потребує подальшого вивчення цієї проблеми. [7]

description: Blooms of microalgae on glaciers and ice sheets are amplifying surface ice melting rates, which are already affected by climate change. Most studies on glacial microorganisms (including snow and glacier ice algae) have so far focused on the spring and summer melt season, leading to a temporal bias, and a knowledge gap in our understanding of the variations in microbial diversity, productivity, and physiology on glacier surfaces year-round. Here, we investigated the microbial communities from Icelandic glacier surface snow and bare ice habitats, with sampling spanning two consecutive years and carried out in both winter and two summer seasons. We evaluated the seasonal differences in microbial community composition using Illumina sequencing of the 16S rRNA, 18S rRNA, and ITS marker genes and correlating them with geochemical signals in the snow and ice. During summer, Chloromonas, Chlainomonas, Raphidonema, and Hydrurus dominated surface snow algal communities, while Ancylonema and Mesotaenium dominated the surface bare ice habitats. In winter, algae could not be detected, and the community composition was dominated by bacteria and fungi. The dominant bacterial taxa found in both winter and summer samples were Bacteriodetes, Actinobacteria, Alphaproteobacteria, and Gammaproteobacteria. The winter bacterial communities showed high similarities to airborne and fresh snow bacteria reported in other studies. This points toward the importance of dry and wet deposition as a wintertime source of microorganisms to the glacier surface. Winter samples were also richer in nutrients than summer samples, except for dissolved organic carbon—which was highest in summer snow and ice samples with blooming microalgae, suggesting that nutrients are accumulated during winter but primarily used by the microbial communities in the summer. Overall, our study shows that glacial snow and ice microbial communities are highly variable on a seasonal basis.

Multifrequency polarimetry of High-Synchrotron Peaked blazars probes the shape of their jets

description: Multifrequency polarimetry is emerging as a powerful probe of blazar jets, especially due to the advent of the Imaging X-ray Polarimetry Explorer (IXPE) space observatory. We study the polarization of High-Synchrotron Peaked (HSP) blazars, where both optical and X-ray emission can be attributed to synchrotron radiation from a population of non-thermal electrons. We adopt an axisymmetric stationary force-free jet model, where the electromagnetic fields are determined by the jet shape. When the jet is nearly parabolic, the X-ray polarization degree is $Π_{\rm X}\sim 15-50\%$, and the optical polarization degree is $Π_{\rm O}\sim 5-25\%$. The polarization degree is strongly chromatic, as $Π_{\rm X}/Π_{\rm O}\sim 2-9$. The chromaticity is due to the softening of the electron distribution at high energies, and is much stronger than for a uniform magnetic field. The Electric Vector Position Angle (EVPA) is aligned with the projection of the jet axis on the plane of the sky. These results compare very well with multifrequency polarimetric observations of HSP blazars. Instead, when the jet is nearly cylindrical, the polarization degree is large and weakly chromatic (we find $Π_{\rm X}\sim 70\%$ and $Π_{\rm O}\sim 60\%$, close to the expected values for a uniform magnetic field). The EVPA is perpendicular to the projection of the jet axis on the plane of the sky. Then, a cylindrical geometry is practically ruled out by current observations. The polarization degree and the EVPA may be less sensitive to the specific particle acceleration process (e.g.,~magnetic reconnection or shocks) than previously thought.

description: Background: Minimally invasive surgery (MIS) for evacuation of spontaneous intracerebral hemorrhage (ICH) has shown promise but there remains a need for intraoperative performance assessment considering the wide range of evacuation effectiveness. In this feasibility study, we analyzed the benefit of intraoperative 3-dimensional imaging during navigated endoscopy-assisted ICH evacuation by mechanical clot fragmentation and aspiration. Methods: 18 patients with superficial or deep supratentorial ICH underwent MIS for clot evacuation followed by intraoperative computerized tomography (iCT) or cone-beam CT (CBCT) imaging. Eligibility for MIS required (a) availability of intraoperative iCT or CBCT, (b) spontaneous lobar or deep ICH without vascular pathology, (c) a stable ICH volume (20–90 ml), (d) a reduced level of consciousness (GCS 5–14), and (e) a premorbid mRS ≤ 1. Demographic, clinical, and radiographic patient data were analyzed by two independent observers. Results: Nine female and 9 male patients with a median age of 76 years (42–85) presented with an ICH score of 3 (1–4), GCS of 10 (5–14) and ICH volume of 54 ± 26 ml. Clot fragmentation and aspiration was feasible in all cases and intraoperative imaging determined an overall evacuation rate of 80 ± 19% (residual hematoma volume: 13 ± 17 ml; p < 0.0001 vs. Pre-OP). Based on the intraoperative imaging results, 1/3rd of all patients underwent an immediate re-aspiration attempt. No patient experienced hemorrhagic complications or required conversion to open craniotomy. However, routine postoperative CT imaging revealed early hematoma re-expansion with an adjusted evacuation rate of 59 ± 30% (residual hematoma volume: 26 ± 37 ml; p < 0.001 vs. Pre-OP). Conclusions: Routine utilization of iCT or CBCT imaging in MIS for ICH permits direct surgical performance assessment and the chance for immediate re-aspiration, which may optimize targeting of an ideal residual hematoma volume and reduce secondary revision rates.

description: Background: Promoting a disruptive innovation in microsurgery, exoscopes promise alleviation of physical strain and improved image quality through digital visualization during microneurosurgical interventions. This study investigates the impact of a novel 3D4k hybrid exoscope (i.e., combining digital and optical visualization) on surgical performance and team workflow in preclinical and clinical neurosurgical settings. Methods: A pre-clinical workshop setting has been developed to assess usability and implementability through skill-based scenarios (neurosurgical participants n = 12). An intraoperative exploration in head and spine surgery (n = 9) and a randomized clinical study comparing ocular and monitor mode in supratentorial brain tumor cases (n = 20) followed within 12 months. Setup, procedure, case characteristics, surgical performance, and user experience have been analyzed for both ocular group (OG) and monitor group (MG). Results: Brain tumor cases using frontal, frontoparietal, or temporal approaches have been identified as favorable use cases for introducing exoscopic neurosurgery. Mean monitor distance and angle were 180 cm and 10°. Surgical ergonomics when sitting improved significantly in MG compared with OG (P = .03). Hand-eye coordination required familiarization in MG. Preclinical data showed a positive correlation between lateral camera inclination and impact on hand-eye coordination (rs = 0.756, P = .01). There was no significant added surgical time in MG. Image quality in current generation 3D4k monitors has been rated inferior to optic visualization yet awaits updates. Conclusions: The hybrid exoscopic device can be integrated into established neurosurgical workflows. Currently, exoscopic interventions seem most suited for cranial tumor surgery in lesions that are not deep-seated. Ergonomics improve in monitor mode compared to conventional microsurgery.

description: Background: In clinical trials with fixed study designs, statistical inference is only made when the trial is completed. In contrast, group sequential designs allow an early stopping of the trial at interim, either for efficacy when the treatment effect is significant or for futility when the treatment effect seems too small to justify a continuation of the trial. Efficacy stopping boundaries based on alpha spending functions have been widely discussed in the statistical literature, and there is also solid work on the choice of adequate futility stopping boundaries. Still, futility boundaries are often chosen with little or completely without theoretical justification, in particular in investigator initiated trails. Some authors contributed to fill this gap. In here, we rely on an idea of Schüler et al. (2017) who discuss optimality criteria for futility boundaries for the special case of trials with (multiple) time-to-event endpoints. Their concept can be adopted to define "optimal" futility boundaries (with respect to given performance indicators) for continuous endpoints. Methods: We extend Schülers' definition for "optimal" futility boundaries to the most common study situation of a single continuous primary endpoint compared between two groups. First, we introduce the analytic algorithm to derive these futility boundaries. Second, the new concept is applied to a real clinical trial example. Finally, the performance of a study design with an "optimal" futility boundary is compared to designs with arbitrarily chosen futility boundaries. Results: The presented concept of deriving futility boundaries allows to control the probability of wrongly stopping for futility, that means stopping for futility even if the treatment effect is promizing. At the same time, the loss in power is also controlled by this approach. Moreover, "optimal" futility boundaries improve the probability of correctly stopping for futility under the null hypothesis of no difference between two groups. Conclusions: The choice of futility boundaries should be thoroughly investigated at the planning stage. The sometimes met, arbitrary choice of futility boundaries can lead to a substantial negative impact on performance. Applying futility boundaries with predefined optimization criteria increases efficiency of group sequential designs. Other optimization criteria than proposed in here might be incorporated.

description: Invasive alien species (IAS) are major drivers of global biodiversity loss, and the poorly regulated international pet trade is a source of emerging and future invaders. Predictions of the likely ecological impacts and risks of such IAS have been significantly enhanced in recent years with new metrics, which require application to many more actual and potential IAS. Hence, this study assesses the potential ecological impacts and risks of two readily available pet trade species: goldfish, Carassius auratus, a species with non-native populations worldwide; and white cloud mountain minnow, Tanichthys albonubes, a species with a limited invasion history to date. First, we compared the per capita feeding rates of these non-native species with two European trophically analogous natives – the stone loach, Barbatula barbatula, and the common minnow, Phoxinus phoxinus – using the Comparative Functional Response method. Second, we used foraging experiments in conspecific pairs to determine synergistic, neutral or antagonistic intraspecific interactions. Third, we performed novel object experiments using the two pet trade species to assess boldness, a known “dispersal enhancing trait”. Goldfish had the highest maximum feeding rates of the four species, while white cloud mountain minnows had the lowest. Neutral interactions were observed for all four species in the paired foraging experiments, with goldfish having the highest consumption and white cloud mountain minnows having the lowest. Goldfish demonstrated greater boldness, being more active during the experimental trials and more likely to approach a novel object than white cloud mountain minnows. Further, combining maximum feeding rates, boldness and species availabilities from our survey of pet shops, we assessed the relative invasion risks (RIR) of the two non-natives. This highlighted goldfish as the higher risk and most worthy of management prioritisation, mirroring its more extensive invasion history. We propose that such metrics have potential to direct future IAS policy decisions and management towards the ever-increasing rates of biological invasions worldwide.

description: Megathrust earthquakes impose changes of differential stress and pore pressure in the lithosphere-asthenosphere system that are transiently relaxed during the postseismic period primarily due to afterslip, viscoelastic and poroelastic processes. Especially during the early postseismic phase, however, the relative contribution of these processes to the observed surface deformation is unclear. To investigate this, we use geodetic data collected in the first 48 days following the 2010 Maule earthquake and a poro-viscoelastic forward model combined with an afterslip inversion. This model approach fits the geodetic data 14% better than a pure elastic model. Particularly near the region of maximum coseismic slip, the predicted surface poroelastic uplift pattern explains well the observations. If poroelasticity is neglected, the spatial afterslip distribution is locally altered by up to ±40%. Moreover, we find that shallow crustal aftershocks mostly occur in regions of increased postseismic pore-pressure changes, indicating that both processes might be mechanically coupled.
