description: Molecular self-assembly is a well-known technique to create highly functional nanostructures on surfaces. Self-assembly on two-dimensional materials is a developing field and has already resulted in the discovery of several rich and interesting phenomena. Here, we review this progress with an emphasis on the electronic properties of the adsorbates and the substrate in well-defined systems, as unveiled by scanning tunneling microscopy (STM). We cover three aspects of the self-assembly. The first one focuses on non-covalent self-assembly dealing with site-selectivity due to inherent moire pattern present on 2D materials deposited on substrates. Modification of intermolecular interactions and molecule-substrate interactions influences the assembly drastically and 2D materials can also be used as a platform to carry out covalent and metal-coordinated assembly. The second part deals with the electronic properties of molecules adsorbed on 2D materials. By virtue of being inert and possessing low density of states near the Fermi level, 2D materials decouple molecules electronically from the underlying metal substrate and allow high-resolution spectroscopy and imaging of molecular orbitals. The moire pattern on the 2D materials causes site-selective gating and charging of molecules in some cases. The last section covers the effects of self-assembled organic molecules on the electronic properties of graphene as revealed by spectroscopy and electrical transport measurements. Non-covalent functionalization of 2D materials has already been applied for their application as catalysts and sensors. With the current surge of activity on building van der Waals heterostructures from 2D materials, molecular self-assembly has the potential to add an extra level of flexibility and functionality for applications ranging from flexible electronics and OLEDs to novel electronic devices and spintronics.

description: Enshrouded in several well-known controversies, dwarf galaxies have been extensively studied to learn about the underlying cosmology, notwithstanding that physical processes regulating their properties are poorly understood. To shed light on these processes, we introduce the Pandora suite of 17 high-resolution (3.5 parsec half-cell side) dwarf galaxy formation cosmological simulations. Commencing with thermo-turbulent star formation and mechanical supernova feedback, we gradually increase the complexity of physics incorporated leading to full-physics models combining magnetism, on-the-fly radiative transfer and the corresponding stellar photoheating, and SN-accelerated cosmic rays. We investigate combinations of these processes, comparing them with observations to constrain what are the main mechanisms determining dwarf galaxy properties. We find hydrodynamical `SN feedback-only' simulations struggle to produce realistic dwarf galaxies, leading either to overquenched or too centrally concentrated, dispersion dominated systems when compared to observed field dwarfs. Accounting for radiation with cosmic rays results in extended and rotationally-supported systems. Spatially `distributed' feedback leads to realistic stellar and HI masses as well as kinematics. Furthermore, resolved kinematic maps of our full-physics models predict kinematically distinct clumps and kinematic misalignments of stars, HI and HII after star formation events. Episodic star formation combined with its associated feedback induces more core-like dark matter central profiles, which our `SN feedback-only' models struggle to achieve. Our results demonstrate the complexity of physical processes required to capture realistic dwarf galaxy properties, making tangible predictions for integral field unit surveys, radio synchrotron emission, and for galaxy and multi-phase interstellar medium properties that JWST will probe.

description: The Fabaceae family contains a shrub tree called Vachellia flava (Syn.: Acacia ehrenbergiana), and considering its ethnopharmacological uses, it is recognized as a significant traditional medicinal herb. We herein aim to evaluate the biological potential of V. flava crude extract, including antioxidant, antimicrobial, antiparasite, and toxicity against normal cells. Furthermore, the chemical composition of the crude extract of V. flava was investigated. Antimicrobial results showed that the crude extract possessed significant activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans at various concentrations. The plant extracts also exhibited high antiparasite activity against Giardia intestinalis and scavenged DPPH• free radicals. An in vitro MTT assay showed no toxicity in normal cells. At the same time, by assaying the in vivo acute toxicity in rats, slight changes in various rat parameters were detected. GC-MS analysis of V. flava identified a phenolic compound as the most abundant constituent, pyrogallol (42.79%), followed by a sugar (4-O-methylmannose; 17.96%), a diterpenoid (1S,3E,4S,5R,7E,11E)-cembra-2,7,11-trien-4,5-diol; 14.49%), and a fatty acid (n-hexadecanoic acid; 12.87%). Considering all the prominent bioactivities, the plant serves as an excellent example to be considered for further phytochemical and pharmacological investigation.

description: Two-dimensional transition metal dichalcogenides (TMDC) have shown promise for various applications in optoelectronics and so-called valleytronics. Their operation and performance strongly depend on the stacking of individual layers. Here, optical second-harmonic generation (SHG) in imaging mode is shown to be a versatile tool for systematic time-resolved investigations of TMDC monolayers and heterostructures in consideration of the material's structure. Large sample areas can be probed without the need of any mapping or scanning. By means of polarization dependent measurements, the crystalline orientation of monolayers or the stacking angles of heterostructures can be evaluated for the whole field of view. Pump-probe experiments then allow to correlate observed transient changes of the second-harmonic response with the underlying structure. The corresponding time-resolution is virtually limited by the pulse duration of the used laser. As an example, polarization dependent and time-resolved measurements on mono- and multilayer MoS$_2$ flakes grown on a SiO$_2$/Si(001) substrate are presented.

description: PAC-Bayes has recently re-emerged as an effective theory with which one can derive principled learning algorithms with tight performance guarantees. However, applications of PAC-Bayes to bandit problems are relatively rare, which is a great misfortune. Many decision-making problems in healthcare, finance and natural sciences can be modelled as bandit problems. In many of these applications, principled algorithms with strong performance guarantees would be very much appreciated. This survey provides an overview of PAC-Bayes bounds for bandit problems and an experimental comparison of these bounds. On the one hand, we found that PAC-Bayes bounds are a useful tool for designing offline bandit algorithms with performance guarantees. In our experiments, a PAC-Bayesian offline contextual bandit algorithm was able to learn randomised neural network polices with competitive expected reward and non-vacuous performance guarantees. On the other hand, the PAC-Bayesian online bandit algorithms that we tested had loose cumulative regret bounds. We conclude by discussing some topics for future work on PAC-Bayesian bandit algorithms.

description: The present study aimed to develop conventional propagation protocols for Paeonia emodi, a threatened and high-value medicinal herb of the Himalayan region. Different experiments were conducted to evaluate the effects of various concentrations of plant growth regulators (PGRs) on seed germination and vegetative propagation (root cuttings) in nursery conditions. Leaves of well-developed plants were used to evaluate phytochemical content and antioxidant activity. Seed germination percentage reached a maximum (78.88 ± 1.25%) with gibberellic acid + abscisic acid treatment (GA3+ABA) at a concentration of 100 µM each. However, 100% sprouting was observed in roots treated with 500 mg L−1 indole-3-butyric acid (IBA). Seeds treated with GA3 (100 µM) induced a maximum plant height (11.98 ± 0.05 cm). Similarly, roots treated with IBA (500 mg L−1) resulted in 35.54 ± 0.84 cm plant height and maximum root diameter (25.18 ± 0.90 mm) in IBA (100 mg L−1) treated plants. Among differently treated plants, total phenolic content (100.95 ± 1.36 mg GAE/g dw) and 2, 2′-azinobis-3-ethylbenzothiazoline-6-sulfonate assay activity (25.24 ± 0.35 mg AAE/g dw) were higher in GA3+ABA (100 µM each) treated seed raised plants. However, vegetatively propagated plants treated with IBA 100 mg L−1 had the highest levels of total phenolics (110.42 ± 3.42 mg GAE/g dw) and 2, 2′-diphenyl-1-picrylhydrazyl assay activity (22.35 ± 0.48 mg AAE/g dw). The results of the study will help in the mass multiplication of the species for large-scale production.

description: This work is devoted to the study of the existence of at least one weak solution to nonlocal equations involving a general integro-differential operator of fractional type. As a special case, we derive an existence theorem for the fractional Laplacian, finding a nontrivial weak solution of the equation \begin{eqnarray*} \begin{cases} (-Δ)^s u=h(x)f(u) & {\mbox{ in }} Ω\\ u=0 & {\mbox{ in }} \mathbb{R}^n\setminus Ω, \end{cases} \end{eqnarray*} where $h\in L^{\infty}_+(Ω)\setminus\{0\}$ and $f:\mathbb{R}\rightarrow\mathbb{R}$ is a suitable continuous function. These problems have a variational structure and we find a nontrivial weak solution for them by exploiting a recent local minimum result for smooth functionals defined on a reflexive Banach space. To make the nonlinear methods work, some careful analysis of the fractional spaces involved is necessary.

COVID-19

description: In December 2019, the first case of Coronavirus was identified. The novel virus appears to be highly contagious and is rapidly spreading worldwide, becoming a pandemic. The disease is causing a high toll of deaths. Effective public health response to a new infectious disease is expected to mitigate and counteract its negative impact on the population. However, time and economic-financial constraints, as well as uncertainty, can jeopardize the answer. Appropriate financing of the health system and ensuring equitable access to health services for all can protect individuals against high medical costs, which is one of the most important goals of any health system. Financing profoundly affects the performance of the health system, and any policy that the health system decides to implement or not directly depends on the amount of available funding. Various countries are injecting new funding to cope with the disease and prevent it faster. In addition to psychological support and increased social participation for the prevention, control, and treatment of COVID-19, extensive financial support to governments by the community should be considered. Developed and rich countries should support countries that do not have financial viability. This disease cannot be controlled without international cooperation. The experience of the COVID-19 should be a lesson for further developing universal health coverage in all countries. In addition to promoting equity in health, appropriate infrastructure is provided to address these crises. Governments should make a stronger political commitment to implement this crucial policy fully.

description: Epoxidation is reaction of the carbon–carbon double bond of fatty acids of vegetable oils. Recent environmental awareness and reduction of world fossil fuel reserves have enforced the need to look for a replacement of mineral oils with environmental friendly and nontoxic vegetable base oils such as epoxy oil. In this study epoxy oil was produced from seed oil using locally available raw material, podo carpus falcatus ('zigba') by carbon-based sulfonated catalyst. This bio-based catalyst was used for epoxidation reactions of podo carpus falcatus seed oil and the study was undertaken by preparing both carbon-based acid catalyst from rice husk at carbonization temperatures (400, 500, 600 ℃) and extraction of vegetable oil from podo carpus falcatus seed. The prepared sulfonated solid acid catalysts were characterized using: bulk density, total acid density, elemental analysis (CNHS), absorbance for methyl orange solution, and (Fourier Transform Infrared Spectroscopy) FT-IR. Based on the above characterization, the catalyst prepared from rice husk at temperature of 600 ℃ was selected for further investigation for epoxidation reaction of podo carpus falcatus seed oil. Podo carpus falcatus seed oil and epoxidized podo carpus seed oil were characterized by acid value (4 mmol KOH/l), Iodine value (121 g/100 g of I2), Gas Chromatography Mass Spectroscopy (GC-MS), FT-IR, Nuclear Magnetic Resonance (NMR) and including other physical properties (density, specific gravity, and kinematic viscosity).The epoxidation reaction experiment was performed at reaction temperatures of 65, 75 and 85 ℃, hydrogen peroxide to the podo carpus falcatus seed oil with molar ratio of 1.5 :1, 2.5:1 and 3.5:1, acetic acid to podo carpus falcatus seed oil molar ratio 0.5:1 and reaction times of 2, 4, and 6 hours. The optimal value of oxirane oxygen content 3.788 % was obtained at 71.89 °C reaction temperature, in 5.1 hours reaction time, and 1.94:1 hydrogen peroxide to oil molar ratio. The relative conversion of double bond was 90.89%. Epoxidized podo carpus falcatus prepared from podo carpus falcatus seed have a good physiochemical and functional properties for epoxidized podo carpus production. and the carbon-based sulfonated catalyst works successfully for epoxidation of podo carpus falcatus seed oil.

description: We use high-resolution zoom-in cosmological simulations to model outflow triggered by radiation and thermal drivers around the central mass accumulation during direct collapse within the dark matter (DM) halo. The maximal resolution is $1.3\times 10^{-5}$\,pc, and no restrictions are put on the geometry of the inflow/outflow. The central mass is considered {\it prior} to the formation of the supermassive black hole seed at a redshift of $z\sim 15.9$, and can constitute either a supermassive star (SMS) of $\sim 10^5\,M_\odot$ surrounded by a growing accretion disk or a self-gravitating disk. The radiation transfer is modeled using the ray-tracing algorithm. Due to the high accretion rate of $\sim 1\,M_\odot\,{\rm yr^{-1}}$ determined by the DM halo, accretion is mildly supercritical, resulting in mildly super-critical luminosity which has only a limited effect on the accretion rate, with the duty cycle of $\sim 0.9$. We observe a fast development of hot cavities, which quickly extend into polar funnels and expand dense shells. Within the funnels, fast winds, $\sim 10^3\,{\rm km\,s^{-1}}$, are mass-loaded by the accreting gas. We follow the expanding shells to $\sim 1$\,pc, when the shell velocity remains substantially, $\sim 5$ times, above the escape speed. The ionization cones formed by the central UV/X-ray completely ionize the cavities. Extrapolating the outflow properties shows that the halo material outside the shell will have difficulty stopping it. We therefore conclude that the expanding wind-driven shell will break out of the central parsec and will reach the halo virial radius. Finally, the anisotropic accretion flow on sub-parsec scales will attenuate the UV/soft X-rays on the H$_2$. Hence, the formation of funnels and powerful outflows around, e.g., SMS, can have interesting observational corollaries.

description: Banana fiber is one of natural fiber and can be produced from pseudo stem with mechanical and chemical treating mechanism. The aim of this paper is producing regenerated cellulosic fiber from banana pseudo stem by using copper amine solution. Banana pseudo stem was collected around Jima zone and the fiber was extracted mechanically. The pseudo stem has around 6.5 w% of fiber and the fiber has a moisture content of 59.3 w% and has a cellulose content of 57-64 %. The analysis was taken which used to know the properties of raw fiber, mercerized fiber and regenerated fiber. Water absorption capacity is one useful technique to determine hydrophilicity of fiber. The water absorption of raw fiber, mercerized fiber and regenerated fiber was 4.85, 3.8 and 1.1 respectively. And the result shows that hydrophilicity of fiber decreases probably because of the hydroxyl group is replaced by sodium ion for mercerization and amine group for regenerated fiber. Other characterization techniques were also proceeded; such that FTIR analysis with a wave length between 4000 and 400 cm -1 , thermal stability of regenerated fiber from a temperature 25 2018 o C to 700 o C with a great mass loss from 200 to 400 o C. And also, the crystallinity of regenerated fiber was calculated by taking reference polymers and gives around 72% crystallinity. The optimum factors obtained from design are time of 60.23 hours, copper amine volume of 66.96ml and concentration for regenerating compound is 1.07M for responses of water absorption capacity is 1.09 and yield of 1.4 gram.

description: Research which has compared co-operative, competitive and individualistic learning environments has been prolific and has focused mostly on achievement levels, problem solving and goals and rewards. Studies specifically into co-operative learning have investigated task structures, including peer tutoring and group investigation models and, more recently, the constructed controversy model. This study is possibly the first to examine simple, short-term co-operative learning structures and their perceived effects on metacognition and motivation. The purpose of this research was to investigate students' perceptions about the extent to which and the ways in which participating in simple, co-operative activities impacted upon their metacognitive skills and their motivation. Thirty-six students from two Year 12 English classes recorded their reflections on participating in the co-operative learning structures in their journals over a period of two weeks. The students then completed a scaled questionnaire and a survey which related to co-operative learning structures, metacognition and motivation. Analysis of the results indicated that the students thought that they gained most metacognitive benefit from the co-operative learning structures of Think -Pair -Share and Inside -Outside -Circle and were most motivated to participate in Pairs -Compare. The findings support the proposition that future research cannot afford to dismiss the impact that some of the simpler co-operative structures appear to have on students' perceptions of their metacognition and motivation. The evidence also suggests that these simple co-operative learning structures should be differentiated in future research in order to identify their distinctive as well as common benefits.

description: Although Mediterranean species demonstrate a strong ability to survive in degraded and arid environments, it is crucial to acknowledge the significant influence that climate change can have on them. Woodlands dominated by Quercus ithaburensis subsp. macrolepis are part of an agroforestry system in the Mediterranean region, hence, the potential changes in its distribution were investigated under future climate and land-use change scenarios through species distribution modeling. The modeling results show that the suitable habitats for the species are mainly concentrated in Greece and the west of Anatolia, which are already natural ranges. In addition, climate has a higher influence on the thriving strength and distribution of the species than land-use, with temperature being the primary factor driving these effects. Therefore, the distribution of the species is predicted to undergo small declines in suitable habitats and to be more influenced by climate change than the combination of land-use and climate change in case of minor temperature increases. However, the synergistic influence of land-use and climate change is expected to have a more adverse impact on the distribution of the species than climate change alone in case of major temperature changes, thus leading to a more significant decrease in the species’ habitats.

description: The Earth's climate has experienced numerous critical transitions during its history, which have often been accompanied by massive and rapid changes in the biosphere. Such transitions are evidenced in various proxy records covering different timescales. The goal is then to identify, date, and rank past critical transitions in terms of importance, thus possibly yielding a more thorough perspective on climatic history. To illustrate such an angle, which inspired the punctuated equilibrium angle on the theory of evolution, we have analyzed 2 key high-resolution datasets: the CENOGRID marine compilation (past 66 Myr), and North Atlantic U1308 record (past 3.3 Myr). By combining recurrence analysis of the individual time series with a multivariate representation of the system based on the theory of the quasi-potential, we identify the key abrupt transitions associated with major regime changes that differentiate various clusters of climate variability. This allows interpreting the time-evolution of the system as a trajectory taking place in a dynamical landscape, whose multiscale features are associated with a hierarchy of tipping points.

Infection prevention

description: Oxidative mechanisms are not only involved in chronic degenerative diseases but also in infectious diseases, among which viral respiratory diseases. Antioxidants have the capability to counteract the action of oxidants by scavenging reactive oxygen species (ROS) and by inhibiting oxidant generating enzymes. Overproduction of ROS and deprivation of antioxidant systems play a major role in COVID-19 occurrence, progression, and severity. Interconnected pathways account for the relationships between oxidative damage and inflammation resulting from an interplay between transcription factors having opposite effects. For instance, Nrf2 downregulates inflammation by inhibiting endogenous antioxidant enzymes such as NQO-1 and HO-1. On the other hand, NF-κB upregulates pro-inflammatory cytokines and chemokines, such as IL-1β, IL-6, IL-8, PGE-2, COX-2, TNF-α, MMP-3, and MMP-4. A central protective role against oxidants is played by reduced glutathione (GSH), which is depleted in SARS-CoV-2 infection. N-acetylcysteine (NAC), a precursor of GSH, is of particular interest as an anti-COVID-19 agent. GSH and NAC hamper binding of the S1 subunit of SARS-CoV-2 spike proteins to the angiotensin-converting enzyme 2 (ACE2) receptor. In addition, NAC and its derivatives possess a broad array of antioxidant and antiinflammatory mechanisms that could be exploited for COVID-19 prevention and adjuvant therapy. In particular, as demonstrated in a previous clinical trial evaluating influenza and influenza-like illnesses, the oral administration of NAC may be expected to decrease the risk of developing COVID-19. Furthermore, at the very high doses used worldwide as an antidote against paracetamol intoxication, intravenous NAC is likely to attenuate the pulmonary and systemic symptoms of COVID-19.
