Physiological Function of Blood Vessels from Uncontrolled Donation after Circulatory Death in Pigs

Donation after circulatory death (DCD) has become increasingly important in kidney transplantation. Challenges, including early graft loss and delayed graft function, remain. Little is known regarding vascular properties. The aim was to examine effects of DCD on renal artery function in a novel pig extended DCD model, extending the time from circulatory arrest to retrieval of the organ to more than 4 hours, making it more feasible to recruit more organs from DCD. Renal and iliac arteries were obtained from animals immediately after euthanasia (fresh) and 4.5hr after DCD. Vessels were also analyzed after 10hr at 4℃ in physiological salt solution (stored). Preparations were mounted for isometric force recording in vitro and examined at optimal stretch for active tension. Iliac arteries were more sensitive to noradrenaline compared to renal artery, possibly reflecting differences in sympathetic control of perfusion in renal and hind limb vascular beds. in endothelial-mediated relaxation. Kidneys from uDCD donors performed poorly after transplantation, as expected, with a somewhat better result if the donor was given the standard protocol, including cooling after two hours. In conclusion, DCD introduces changes both in contractile function and endothelium-mediated relaxation of renal arteries. Effects were more pronounced than in iliac artery, suggesting that DCD could be one factor affecting the functional circulation of the donor kidney after transplantation. Further studies of uDCD subject to reconditioning before transplantation is underway to study the reversibility of changes to the endothelial function after our uDCD protocol. an µg/kg
Low-Dimensional Subspace Estimation of Continuous-Doppler-Spread Channel in OTFS Systems

Orthogonal time frequency space (OTFS) has shown to be a promising modulation technology that achieves the robust wireless transmission in high-mobility environments. The high mobility incurred Doppler effect in OTFS system, is represented as a continuous and relatively large band in the Doppler frequency. It yields the equivalent channel responses (ECRs) in the system change significantly within one symbol block, posing a challenge to channel estimation (CE) or tracking. In order to tackle this issue, in this paper, a set of transform-domain basis functions is designed to span a low-dimensional subspace for modeling the OTFS channel. Then, the CE can be performed by estimating a few projection coefficients of ECRs in the developed subspace, with training pilots. According to the individual transmission characteristic of OTFS signal, we propose a corner-inserted pilot pattern, which targets the low pilot overhead and satisfactory CE performance. Moreover, an OTFS signal detector, leveraging the time-domain channel equalization, linear-complexity interference cancellation and delay-Doppler domain maximal ratio combining detection, is developed to retrieve the transmitted data symbols. The simulations show the precisely estimated ECRs enable the detector to ideally demodulate 256-ary quadrature amplitude modulation signaling, under a velocity of 550 km/h at 5.9 GHz carrier frequency.
Retrospective Analysis of Graduates’ Outcomes in a Post-Professional Occupational Therapy Doctorate Program

Abstract There are limited studies within occupational therapy literature assessing the outcomes of advanced degrees. Specifically, there is a scarcity of literature about the benefits of completing a post-professional occupational therapy doctorate (POTD) program. The purpose of this study was to retrospectively examine graduates’ professional and personal outcomes at a midwestern university with an established POTD program. A total of 64 graduate exit surveys completed by POTD graduates between the years of 2008 and 2017 were analyzed using a mixed methods research design. Emergent categories from the data included a greater sense of self-empowerment and confidence, expanded career opportunities, and increased professional knowledge and skills. Quantitative data indicated new employment opportunities and increased pay. Overall, graduates reported increased personal and professional growth, however continued research regarding the benefits of completing a POTD is needed to help guide occupational therapists considering an advanced degree.
Your Future Employer: Employer Branding, Reputation, and Social Media

This study examines employer branding and the relationship between corporate reputation, social media, and the intention of potential applicants to seek future employment. The researchers deployed a structured questionnaire to gather data from national service personnel in Ghana via the WhatsApp platform using a Google Form hyperlink. The proposed conceptual framework was tested based on 581 generated responses. The researchers depended on ADANCO 2.1 software for analysis. This helped in producing the PLS-SEM. The results indicate that the application value, development value, and social value positively impact reputation, which successively influences the intent to apply. The findings also reveal that, where social media influence intention to apply, it does not positively impact corporate reputation. The limitation of this study and directions for future studies are presented.
Modeling and Simulation Study of an Industrial Radial Moving Bed Reactor for Propane Dehydrogenation Process

Abstract An accurate model is required to optimize the propane dehydrogenation reaction carried out in the radial moving bed reactors (RMBR). The present study modeled the RMBR using a plug flow reactor model incorporated with kinetic models expressed in simple power-law model. Catalyst activity and coke formation were also considered. The model was solved numerically by discretizing the RMBR in axial and radial directions. The optimized kinetic parameters were then used to predict the trends of propane conversion, temperature, catalyst activity and coke content in the RMBR along axial and radial directions. It was found that the predicted activation energies of the propane dehydrogenation, propane cracking and ethylene hydrogenation were in reasonable agreement with the experimental values reported in the literature. The model developed has accurately predicted the reaction temperature profile, conversion profile and catalyst coke content. The deviations of these simulated results from the plant data were less than 5%.
Gelosaite, BiMo6+(2–5x)Mo5+6xO7(OH)·H2O (0 ≤ x ≤ 0.4), a new mineral from Su Senargiu (CA), Sardinia, Italy, and a second occurrence from Kingsgate, New England, Australia

Abstract Gelosaite, BiMo6+(2-5x)Mo5+6xO7(OH)·H2O (0 ≤ x ≤ 0.4), occurs at the type locality in quartz veins hosted by granitic rocks at Su Senargiu, near Sarroch, Sardegna, Italy. The name is in memory of Mario Gelosa (1947-2006) who first found the mineral. The mineral also occurs in the oxidized zones of the Old 25 and Wolfram pipes at Kingsgate, New South Wales, Australia. Both the mineral and its name have been approved by the IMA CNMNC (IMA 2009-022). Gelosaite occurs as yellow, yellowish green, and pale blue, prismatic crystals with a white streak. It is transparent with an adamantine luster, non-fluorescent, brittle, and has a conchoidal fracture. Mohs hardness is ~3. The mineral is monoclinic, space group P21/n, with a = 5.8505(4), b = 9.0421(6), c = 13.917(1) Å, β = 100.42(1)°, V = 724.1(1) Å3, Z = 4 (yellow Su Senargiu crystal); a = 5.8570(5), b = 9.0517(8), c = 13.992(1) Å, β = 100.44(1)°, V = 729.5(1) Å3, Z = 4 (pale blue Su Senargiu crystal); a = 5.837(3), b = 9.040(5), c = 13.904(7) Å, β = 100.64(1)°, V = 721.0(6) Å3, Z = 4 (blue Kingsgate crystal). Strongest lines in the powder X-ray pattern [d (Å)(Irel)] are 4.83(100), 3.41(21), 3.30(25), 3.015(50), 2.755(60), 2.080(50), 1.688(20), and 1.509(30). The single-crystal X-ray structure of gelosaite was determined for three separate crystals, two from Su Senargiu and one from Kingsgate. The structure consists of layers of distorted MoO6 octahedra, plus minor amounts of interstitial Mo ions, and layers made up of eight-coordinate Bi3+ ions, plus further small amounts of interstitial Mo ions. The theoretical Mo(VI) end-member has the stoichiometry BiMo6+2O7(OH)·H2O and excess Mo in the interstices requires increasing amounts of Mo(V) to be present. The theoretical Mo(V) end-member has the stoichiometry BiMo5+2.4O7(OH)·H2O
Time-consistent investment-reinsurance strategy with a defaultable security under ambiguous environment

This paper considers an investment and reinsurance problem with a defaultable security for an insurer in an environment with parameter uncertainties. Suppose that the insurer is ambiguous about the insurance claims. Specifically, the insurance claim is exponentially distributed and the rate parameter is uncertain. The insurer is allowed to invest in a financial market consisting of a risk-free bond, a stock whose price process satisfies the Heston's SV model and a defaultable bond. Moreover, the insurer is allowed to purchase proportional reinsurance and aims to maximize the smooth ambiguity utility proposed in Klibanoff et al. [ 15 ]. By applying stochastic control approach, we establish the extended HJB system and derive the time-consistent investment-reinsurance strategy for the post-default case and the pre-default case, respectively. Finally, a sensitivity analysis is provided to illustrate the effects of model parameters on the equilibrium reinsurance-investment strategy under the smooth ambiguity.

Collective models are built on the basis of the «cellular emotional automate» proposed by the authors. The possibility of using the standard rules for cellular automate in modeling the emotional behavior of collectives is shown. The proposed approach can be attributed to artificial intelligence technologies.
3-D Object Imaging Method With Electromagnetic Vortex

The electromagnetic (EM) vortex imaging has demonstrated superior performance in target detection and imaging with azimuthal super-resolution. However, the restricted elevation resolution degrades the acquisition of target spatial information, which limits the development of the radar imaging technology based on orbital angular momentum (OAM). This article offers a solution to achieve the 3-D EM vortex imaging, by effectively utilizing relative motion between radar and target in the line-of-sight (LOS) direction. First, the forward-looking radar imaging scenario is presented, the 3-D echo model is derived, and the characteristics are analyzed as well. Second, the imaging method, based on the back-projection (BP) and spectrum estimation method, is proposed to obtain the target’s 3-D focused image. Furthermore, the influence factors about the elevation resolution are analyzed by the point spread function (PSF). Finally, simulations are carried out to verify the effectiveness of the theoretical analyses.
Anti-urease, total phenolic content and antioxidant activities of some Inula l. (Asteraceae) taxa in Turkey

The genus Inula belongs to family Asteraceae and it is medicinally important because it possesses cytotoxic, anticancer, hepatoprotective, antibacterial and anti-inflammatory properties. The aim of this research was to explore antioxidant and anti-urease activities of fifteen Inula taxa in Turkey. Ethanol extracts of Inula taxa were obtained by Soxhlet extraction. Antioxidant activity was determined through total antioxidant activity, total phenolic content and copper reducing antioxidant capacity (CUPRAC) analyses. The highest total phenolic content and total antioxidant capacity were found in I. orientalis (158.54? 0.002 ? g GAE/mL) and I. macrocephala (189.16? 0.002 ? g AAE/mL). CUPRAC activity increases with the increasing concentration of the extracts and the standard. Moreover, all the tested plants exhibited better anti-urease activity than standard thiourea except for I. anatolica and I. thapsoides subsp. thapsoides. Results obtained from this study demonstrate that Inula species might be utilized as a probable natural source in the pharmaceutical and food industries but further and more specific studies are needed to determine active antioxidative and anti-urease compounds in the extracts.
The long noncoding RNA-30162 is regulated by commensal microbiota and modulates CCL24 and ARG1 in macrophages

Background Alveolar macrophages (AMs) are the largest number of innate immune cells in the distal lung. AMs have critical roles in maintaining immunological homoeostasis and host defense in the lung and are inherently suppressive. Immune homeostasis depends on the integrity of microbiome, which contribute to appropriate maturation and priming of the immune system. The absence of commensal microbiota can lead to changes in AM function; however, little is known about the effect of long non-coding RNA (lncRNA) molecules in this process. Results Here, by lncRNA microarray analysis using AM samples from antibiotic-treated (Abt) mice, we found that treatment with antibiotics resulted in differential expression of numerous lncRNAs in AMs. Target genes of differentially expressed lncRNAs were associated with several biological pathways, including regulation of immune system processes, angiogenesis, cell differentiation, and chemotaxis, among others. Notably, lncRNA-30162 expression levels were up-regulated in AMs from Abt mice. Moreover, knockdown of lncRNA-30162 expression significantly reduced CCL24 and ARG1 levels in macrophages. Conclusions These findings indicate that microbiome can regulate the expression of lncRNA-30162 in AMs, identifying a molecular mechanism underlying lncRNA-mediated regulation of macrophage functions.
Benefits of short-term training with vibrotactile biofeedback of trunk sway on balance control in multiple sclerosis

Background and aims: Patients with multiple sclerosis (MS) suffer from diminished balance control. We examined whether 4 sessions of training with vibrotactile biofeedback (VTfb) of trunk sway could improve their balance control and provide a carry-over effect. Methods: Baseline trunk sway was first measured for 15 MS patients. Then they received head mounted VTfb of trunk sway which was directionally active when trunk sway exceeded limits set using the baseline assessments. Stance and gait tasks were trained 2 times weekly for 2 weeks with VTfb. Assessments with VTfb were performed at the end of each week. Two weeks later balance was assessed without VTfb to determine if a carry-over effect was present. Results: Assessments with VTfb showed a significant decrease in trunk sway after 1 and 2 weeks of VTfb training (p<0.02). Carry-over improvements were also present (p<0.02). The greatest effects were found for tests of standing eyes closed stance on foam which resulted in a 59% decreased pitch sway angle (p=0.002) with VTfb and a 51% reduction (p=0.03) carry-over effect. Conclusions: This study indicates that balance control in MS patients improves rapidly after one week of training with VTfb and more slowly subsequently. The carry-over effect lasted at least 2 weeks. Future studies should determine, with more weeks of VTfb training, the time course of the slower balance and carry-over improvements following the first rapid improvement in balance control. We conclude that training with VTfb of trunk sway significantly improves balance control in MS patients, and could possibly reduce falls.
Short Term Effect of Virtual Reality on Tear Film Stability and Ocular Discomfort

Virtual reality (VR) has been integrated and used with smartphones as one of the digital entertainments such as in gaming and movie streaming. With emergent of various VR brands in the market, it concerns the public on the possible side effects of VR on the ocular performance specifically on tear film stability and ocular discomfort. The purpose of this study was to compare the change on non-invasive keratograph tear break-up time (NIKBUT), tear meniscus height (TMH) before and after the use of VR for 30 minutes, and to measure the ocular discomfort after the use of VR quantitatively. Thirty-two subjects were recruited in this study and all the subjects were divided randomly into two groups; VR and laptop (used as a control) groups. Each subject needed to watch a movie for 30 minutes using the respective devices. The changes of tear film stability and ocular discomfort before and after the use of the devices were then compared and the results showed that there was no significant difference (p>0.05) after 30 minutes of the use. Comparison of the ocular parameters between the devices on post-watching activities was also not significant (p>0.05). Use of VR did not give any signs of dryness to the eyes and it can be used without any discomfort even after 30 minutes usage of the devices.
Fluorescence Resonance Energy Transfer (FRET)

FRET involves the excitation of a donor fluorophore by incident light within its absorption spectrum. This radiative absorption elevates the donor fluorophore to a higher-energy excited state that would normally decay (return to the ground state) radiatively with a characteristic emission spectrum. If, however, another fluorophore molecule (the acceptor) exists in proximity to the donor with its energy state characterized by an absorption spectrum that overlaps the emission spectrum of the donor, then the possibility of non-radiative energy transfer between donor and acceptor exists. As an example, Figure 1 shows the overlap of the cyan fluorescent protein (CFP) emission spectrum and the yellow fluorescent protein (YFP) absorption spectrum; this pair supports a strong FRET interaction.
Theoretical study of phase transition of 3C-SiC under high pressure

Based on the generalized gradient approximation, we have investigated the phase transition of 3C-SiC from ZB to NaCl structure using first-principles method, and obtained the accurate symmetry Imm2 (previously regarded as lower symmetry Cmm2 and Pmm2) of the intermediate phase. The relative activation enthalpy 0.647eV is close to the result of Catti. The obtained transition pressure 69GPa is lower than the experimental value of 100GPa which may be attributed to the hysteresis of the phase transition. Meanwhile, the energy bands for ZB- and NaCl-SiC were also calculated and discussed, the results suggest that the phase transition of 3C-SiC is accompanied by an electronic transition from semiconducting to metallic character besides the structure reconstruction, which may be useful for the accurate determination of the transition pressure.
Effect of Sequence Padding on the Performance of Protein-Based Deep Learning Models

Background The use of raw amino acid sequences as input for protein-based deep learning models has gained popularity in recent years. This scheme obliges to manage proteins with different lengths, while deep learning models require same-shape input. To accomplish this, zeros are usually added to each sequence up to a established common length in a process called zero-padding. However, the effect of different padding strategies on model performance and data structure is yet unknown. Results We analysed the impact of different ways of padding the amino acid sequences in a hierarchical Enzyme Commission number prediction problem. Our results show that padding has an effect on model performance even when there are convolutional layers implied. We propose and implement four novel types of padding the amino acid sequences. Conclusions The present study highlights the relevance of the step of padding the one-hot encoded amino acid sequences when building deep learning-based models for Enzyme Commission number prediction. The fact that this has an effect on model performance should raise awareness on the need of justifying the details of this step on future works.

Chemical, physicochemical analysis and sensory evaluation of the novel formulation of tea based (Camellia sinensis L.) natural carbohydrate-electrolyte replenishing drink (sports drink)

Sports drinks are consumed as a nutritive supplement by the sportsmen. Artificiality of those formulations, increases the unreliability over the consumers regarding health effects. The created objectives were formulated, tea based sports drinks by using Ceylon tea which matches the plasma osmolality. Sensory evaluations were done to investigate the market position and the performance of tea based sports drinks and results demonstrated a higher consumer preference on tea based sports drinks than that of commercially available drinks. To reveal the health benefits, total phenolic content (TPC), total flavonoid content (TFC), total antioxidant capacity (TAC ) and content of catechins were checked by using modified Folin-Ciocalteu method, colorimetric method, ferric reducing antioxidant power (FRAP) assay and high-performance liquid chromatography (HPLC) respectively. Significantly, highest TPC (1.852 ± 0.021 mg GAE/mL) was observed in Ceylon black tea sports drink while the highest TFC (1.252 ± 0.006 mg RE/mL), TAC (27.916 ± 0.121 mg TE/mL), epicatechin (1.07 mg/300 mL) and epigallocatechin gallate (8.29 mg/300 mL) contents were present in Ceylon green tea sports drink. According to the pH, titratable acidity (TA) and total soluble solid (TSS), higher acidity ranges and higher TSS contents were recorded by commercially available samples. Accordingly, the addition of tea demonstrated the enhancement of health benefits and thereby, the novel formulations can be concluded as healthy natural sports drinks.
Review of An Integrated Air-Vinasse Treatment-To-Food, Energy, Water, And A Novel Mosquito-Combatant Soil Amendment

Industrial waste has been an international concern for decades. In addition to pollution concerns, other problems assailing humanity include global hunger, lack of clean water in many parts of the world, and the rising cost of energy production. In order to remediate an environmental pollution issue, and, simultaneously, to generate three main items that are essential to humanity, the novel Integrated Air-Vinasse Treatment-to-Food, Energy, Water, and a Novel Mosquito-Combatant Soil Amendment was conceptualized [1]. This report reviews the said novel integrated air-vinasse treatment-to-co-products process: TAOS (Three and One Significant products). In this study, other vinasse treatment alternatives are also reviewed. A succinct description of the five main stages of the TAOS process is summarized. Biogas treatment technologies are reviewed. The novel concept of a vinasse-generated mosquito-combatant fertilizer is revealed. A process flow diagram of the TAOS process is shown.
The nexus of tourism spending with economic performance: A panel data analysis for the Eurozone area

The paper investigates the nexus of tourism spending (i.e. leisure and business tourism spending) with economic performance (i.e. GDP and employment) for the Eurozone countries, during the period 20002018, employing sophisticated panel data analysis techniques. The issue is salient, given that within the Eurozone economic space the abolition of border impediments has released dynamics and brought into surface a new mix of opportunities, threats and challenges that has been changing the balance between centripetal and centrifugal forces. The findings of the paper identify the long-run equilibrium and confirm the bi-directional relationships among the variables considered, thus contributing to the discussion on the relationship between tourism and economic performance.
