Wasserstein Barycenter for Multi-Source Domain Adaptation

Multi-source domain adaptation is a key technique that allows a model to be trained on data coming from various probability distribution. To overcome the challenges posed by this learning scenario, we propose a method for constructing an intermediate domain between sources and target domain, the Wasserstein Barycenter Transport (WBT). This method relies on the barycenter on Wasserstein spaces for aggregating the source probability distributions. Once the sources have been aggregated, they are transported to the target domain using standard Optimal Transport for Domain Adaptation framework. Additionally, we revisit previous single-source domain adaptation tasks in the context of multi-source scenario. In particular, we apply our algorithm to object and face recognition datasets. Moreover, to diversify the range of applications, we also examine the tasks of music genre recognition and music-speech discrimination. The experiments show that our method has similar performance with the existing state-of-the-art.
Storage of Miscanthus-derived carbon in rhizomes, roots, and soil

Abstract: Compared with annual crops, dedicated perennial bioenergy crops are ascribed additional benefits in terms of reduced greenhouse gas emissions; these benefits include increased carbon (C) storage in soil. We measured Miscanthus-derived C in rhizomes, roots, and 0–100 cm soil beneath three 16-yr-old stands established on sandy soils at two experimental sites in Denmark. Miscanthus C in soil was estimated from changes in the natural abundance of 13C. In the 0–20 cm depth, soil C derived from Miscanthus made up to 15–18% of the soil total C. In the 20–50 cm and 50–100 cm depth, Miscanthus C accounted for less than 7% and 5% of the soil total C, respectively. After 16 yr, the total quantity of Miscanthus C in 0–20 cm ranged from 11.9 to 18.2 Mg C ha−1, of which 23–34% was in rhizomes and roots, substantiating their crucial contribution to soil C storage. Future studies should prioritize the seasonal and annual dynamics of C stored in rhizomes and roots, and the fate of these C pools following termination of Miscanthus stands.

1Department of Neurology, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, 325000, People’s Republic of China; 2Department of Cardiac Care Unit, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, 325000, People’s Republic of China Objective: Pneumonia is a common complication in patients with stroke. There was a close relationship between serum iron and inflammatory response. This study aimed to explore the relationship between serum iron levels and stroke-associated pneumonia (SAP). Methods: Patients with acute stroke were recruited from the First Affiliated Hospital of Wenzhou Medical University and divided into SAP group and Non-SAP group. The demographic and clinical data of the patients were collected via the medical records, and the blood samples were collected within 24 hours after admission. The predictive value of serum iron to SAP was evaluated by receiver operating characteristic curve (ROC) and binary Logistic regression models. A restricted cubic spline (RCS) was used to furtherly clarify the relationship between serum iron and the risk of SAP. Results: A total of 906 participants were enrolled, including Non-SAP group (n = 755) and SAP group (n = 151). Serum iron levels in the SAP group were significantly lower than those in the Non-SAP group (9.77±5.61 vs 14.01±6.80, P < 0.001). Logistic regression showed that patients with high serum iron levels (≥7.8μmol/L) showed a lower risk of SAP (OR=0.43, 95% CI, 0.27–0.69, P < 0.001). Besides, the RCS model showed that there was an L-shaped relationship between the serum iron and risk of SAP (P for non-linearity: 0.014). Conclusion: Low serum iron level was a risk factor for SAP, and there was an L-shaped relationship between them. Stroke patients with low serum iron levels should be alert to the risk of SAP.

INFLUENCING FACTORS AFFECTING YOUNG PEOPLE’S ATTITUDE TOWARDS ONLINE ADVERTISING: A SYSTEMATIC LITERATURE REVIEW

Young people are constantly targeted by online advertisements. This systematic literature review aims to identify the principal factors that influence young people’s attitude towards online advertising. It seeks to understand if the influence of online advertising is dependent on gender and age differences in young people. The methodology involves the systematic review of empirical studies published from 1994 to 2020 and identifies the factors that impact young people’s attitude towards online advertising. The review commences with a scoping study and follows the PRISMA structure, which includes identifying studies, screening and evaluation, the analysis and synthesis of studies, and the presentation of the final studies. This work reveals two main observations from a thematic content analysis of the appraised studies. The first relates to the principal factors influencing young people’s attitude towards advertising. These factors comprise informativeness, entertainment, irritation, credibility, personalisation, and interactivity. In general, studies show that when informativeness, entertainment, credibility and interactivity are present, the more positive the attitude towards advertising is, while irritation fosters an unfavourable attitude. Studies provide a dichotomous stand on personalisation. The second relates to young people’s age and gender. Our review notes that earlier studies lack focus on audiences predominantly between 10 and 15 years.
Clinical Analysis and Perinatal Outcome in Pregnant Patients with COVID-19

Background: Severe acute respiratory syndrome Corona virus 2 (SARS-CoV-2) is the felon responsible for the extraordinary global pandemic of COVID-19 disease. As per the world health organization WHO) updates dated 12 th April 2021 the total number of cases worldwide were 135,6,46,617 out of which 399,277 were reported in Saudi Arabia, as the number of the Covid patients is increased, the number of pregnant patients effected by the disease are also increasing. We therefore planned this study to do the clinical analysis of the pregnant patients with COVID-19 and to see the effect of the disease on the perinatal outcome. Objective: The purpose of the study was to prove the null hypothesis that perinatal morbidity is increased with severity of the Covid 19 effected pregnant patients. Material and Methods: It was a prospective observational study. All the patients who presented at term in labor with singleton pregnancy and with positive nasopharyngeal swab in last 10 days were included in the trial. While the women who had Preterm labor, multiple pregnancy and any other medical disorder were excluded from the study. The duration of the study was 6 months (01/09/202028/02/2021) and was conducted in the labor ward of Dr. Sulaiman Al Habib Hospital, Sweidi, Riyadh, Saudi Arabia. Results: The total numbers of patients enrolled to the trial were 45. The 73% of the study population presented with mild symptoms (n=33) and moderate and severe symptoms were observed in 22.2% (n=10) and 4.4% (n=2) of the population respectively. The 5-minute Apgar score was compared in three groups and was found significantly lower in patients having moderate and severe Covid symptoms (P-value was 0.003). However, the difference in cord pH and NICU (neonatal intensive care unit) admission was not found statistically significant. No risk of the vertical transmission was found when calculated by doing the neonatal swab within 24 hours. The prevalence of Cesarean section was higher in patients having moderate and severe symptoms, though the difference was not found statistically significant. Female gender prevalence was observed in patients having moderate symptoms (70%, n=07). Conclusion: On the basis of our observations we hereby reject our hypothesis that the perinatal morbidity is increased in patients having moderate or severe Covid symptoms.
Aronia melanocarpa Products and By-Products for Health and Nutrition: A Review

Due to factors such as cultivar, fertilization, maturation or climate conditions, as well as the date of their harvest, chokeberries (Aronia melanocarpa) differ in their content of minerals, vitamins, carbohydrates, amino acids, organic acids, fats, aroma compounds and especially polyphenols, substances exerting a beneficial impact on health. The total content of the most important ingredients, polyphenolic compounds, influence many proven chokeberry activities like antioxidative, anti-inflammatory, hypotensive, antiviral, anticancer, antiplatelet, antidiabetic and antiatherosclerotic, respectively. Polyphenolic compounds such as anthocyanins, flavonoids, procyanidins and phenolic acids in different rates and amounts are responsible for all mentioned activities. In the human body, they undergo different biotransformative processes strengthening their bioactivity inside and outside cells. The popularity of chokeberry has been significant lately because of its effects on human health and not just because of its nutritional value. The main interest in this review has been refocused on the chokeberry benefits to human health, nutritional contribution of its components, particularly polyphenolic compounds, and its physiological effects.
Current Status of Emerging PV Technologies: A Comparative Study of Dye-Sensitized, Organic, and Perovskite Solar Cells

The imminent depletion of conventional energy sources has motivated the advancement of renewable energy technologies. Third-generation photovoltaic technologies, such as dye-sensitized solar cells (DSSCs), organic solar cells (OSCs), and perovskite solar cells (PSCs), are being developed as alternatives to silicon solar cells. In recent years, there has been considerable interest in the market development of these emerging photovoltaic technologies, especially for sustainable solar energy applications. However, these technologies have not yet reached the maturity required for large-scale commercialization. Further research is required in order to improve the efficiency and stability of these devices, while keeping their production costs to a minimum. In this study, a comparative assessment of DSSCs, OSCs, and PSCs is conducted and the current state of the art of these promising technologies is investigated. Advanced techniques and research trends are examined from the perspective of novel materials, device modelling, and innovative device structures. The comparative advantages and limitations of each of these photovoltaic technologies are assessed in terms of device efficiency, durability, ease of fabrication, and performance-price ratio. Emphasis is placed on assessing the potential of these solar cell technologies for sustainable solar energy applications. Finally, the future outlook of these technologies is featured, and avenues for progress beyond the state of the art are explored.
Cytogenetical Investigations in Musaceae III. Meiotic studies in diploid Musa species and banana varieties of India1

The success in banana breeding depend on the ability to breed diploid male parents, which are dwarf, agronomically superior, disease resistant and are male fertile. These can be crossed with restitution nuclei forming diploid or triploid females like Gros Michel (a triploid) to ob tain commercially acceptable triploids and tetraploids (for details please see Rowe and Rich ardson 1975). The present day triploid bananas (AAB, ABB) seem to have originated the same way in India (Agarwal under publication). Previous cytological works on banana were mostly confined to determination of chromosome numbers in different varieties (Roy and Sharma 1951, Govindaswami 1962, Raman et al. 1970). The present investigations were undertaken to study detailed meiotic behaviour of two species of Musa and eleven banana varieties grown in India, and to find out the species/varieties which can be used for breeding diploid fertile males and others which show restitution nuclei formation, for use as females in synthesis of triploids.
Induction of Plantlet Regeneration on Shallot (Allium cepa var. Aggregatum)

Micropropagation is an alternative method for producing pathogenic contamination-free shallots seedlings. The aim of this research was to determine the optimum balance of auxin-cytokinin and sucrose concentration in stimulating the plantlet regeneration on shallot. The research was conducted from March to August 2019. In this study, the auxin and cytokinin treatment (1-5 ppm) were used in the format of a randomized complete block design in three replications. The basal plate containing a shoot bud was excised from healthy bulb and used as planting material. The explants had been through a sterilization process and was cultured aseptically in medium containing each treatment. Culture medium contained 7 g.L agar powder and were adjusted at pH 5.8 before autoclaving. The multiple shootlet (10 weeks of cultured) were then subcultured for bulblet formation in MS medium supplemeted with BAP dan succrose (3-9%). The basal plate containing a shoot bud was excised from healthy bulb and used as planting material. The explants had been through a sterilization process and was cultured aseptically in medium containing each treatment. Culture medium contained 7 g L agar powder and were adjusted at pH 5.8 before autoclaving. The results showed that the use of 1⁄2 MS media could increase the efficiency of using nutrient solution of tissue culture media. Micro shoot formation can be initiated on 1⁄2 MS medium with the addition of 1 ppm BAP (1.36 shoots / explants). This media also produced the best response for the number of micro roots (5.63 roots / explants), and the number of micro leaves (3.91 leaves). However, the difference in composition of nutrient in culture media was not able to accelerate the time of growth of shoots, roots and leaves. Further subculture in 1⁄2 strength of MS medium containing of BAP and sucrose 6% increased shoot, root and bulblet formation (13.3 shoots, 41.3 roots and 10.7 bulblets).

Solid-State Electrochemical Energy Storage Based onSoluble Melanin

Biocompatible and biodegradable powering materials are appealing systems for biomedical and electronic devices. Melanin is a natural and multifunctional material with redox capability, which is of great interest in electrochemical energy storage functionalities. In our work, we explored the use of soluble melanin derivatives as active materials for symmetric solid-state supercapacitors operating in the dark and under illumination. We observed that our devices were photo-pseudocapacitive. Additionally, under illumination, our best device showed a specific capacitance of 57.7 mFg−1 at a scan rate of 0.01 Vs−1, with a decrease of 53% in resistance compared to that in the dark. Our outcome suggests that soluble melanin is a promising material for solid-state powering elements in wearable and environmentally friendly devices.
Analysis of Regional Disparity Among Regencies/Cities and the Correlation with Economic Growth North Sumatera in 2010-2019

This research is aimed to find out the level of regional disparity, the effects of government expenditure, natural resources, and the investment toward regional disparity among regencies/cities in North Sumatera Province, and the relationship between the inequality and economic growth of North Sumatera Province in 2010-2019. Using secondary data, the research applies Williamson index analysis technique to measure the development disparity. The panel regression analysis; Common Effect, Fixed Effect and Random Effect; is used to analyze the effects of government expenditure, investment, and natural resources toward regional disparity in North Sumatera in 2010-2019. This research also uses Product Moment Correlation and Regression Curve Estimation to find out the correlation between the disparity and economic growth. The result of the study shows that the level of regional disparity in North Sumatera Province is very high. Government expenditure, natural resources significantly affect the regional disparity, whereas the investment does not significantly affect the disparity. The correlation between the growth economy and regional disparity indicates a very weak negative correlation. Thus, the data cannot be used to explain the correlation between economy growth and development disparity in North Sumatera Province in 2010-2019.
Calculating characteristic timescales for environmental decoherence in the presence of thermal gravitons

Different models show the effects of environmental decoherence on a quantum system due to various environments of interest. One important quantity within these models is the decoherence time, which tells us how quickly environments wash away the coherence of local measurements. We can describe this effect as the quantum system becoming entangled with the environment, whereupon any superposition that existed at the level of the system becomes a global phenomenon. In the following work, we make use of the scattering model first introduced by Joos and Zeh in 1973, and later improved through the work of Gallis, Fleming, Adler, and Hornberger to find decoherence times of a point mass, dielectric sphere. We will do this in the presence of two different graviton environments first, a cosmic gravitational wave background (CGWB), and later a flux of gravitons emanating from a stellar core. We compare these same quantities in the corresponding photon environments which include the cosmic microwave background (CMB) and photons from stellar cores. Results show decoherence times much longer than those corresponding to photons. This is consistent with the known fact that gravity being the weakest of the four fundamental forces weakly interacts with matter, especially for smaller less massive objects. We then show this weak interaction manifests itself in decoherence times and gives us an idea for the numbers involved with gravitational interactions and provides a better intuition for the scale at play. Furthermore, this exploration allows us to explore divergence in the differential cross section for gravitons scattering off the gravitational field of a point mass. This issue differs from the corresponding problem in Coulomb scattering (which exhibits the same divergence behavior) since gravity only deals with mass and involves no differences in charge. This makes finding a finite result for the differential cross section of gravitons an interesting problem and we present one solution below.
Improved Deterministic (Δ+1) Coloring in Low-Space MPC

We present a deterministic O(log log log n)-round low-space Massively Parallel Computation (MPC) algorithm for the classical problem of (Δ+1)-coloring on n-vertex graphs. In this model, every machine has sublinear local space of size n^φ for any arbitrary constant φ \in (0,1). Our algorithm works under the relaxed setting where each machine is allowed to perform exponential local computations, while respecting the n^φ space and bandwidth limitations. Our key technical contribution is a novel derandomization of the ingenious (Δ+1)-coloring local algorithm by Chang-Li-Pettie (STOC 2018, SIAM J. Comput. 2020). The Chang-Li-Pettie algorithm runs in T_local =poly(loglog n) rounds, which sets the state-of-the-art randomized round complexity for the problem in the local model. Our derandomization employs a combination of tools, notably pseudorandom generators (PRG) and bounded-independence hash functions. The achieved round complexity of O(logloglog n) rounds matches the bound of log(T_local ), which currently serves an upper bound barrier for all known randomized algorithms for locally-checkable problems in this model. Furthermore, no deterministic sublogarithmic low-space MPC algorithms for the (Δ+1)-coloring problem have been known before.
