description: Pemasangan PLTS rumahan diyakini dapat menghemat biaya pengeluaran listrik bulanan rumah tangga. Namun ada dugaan dari pengguna mengenai produksi listrik dari solar panel yang akan mengalami penurunan jika kondisi setempat berawan dan hujan terutama pada saat musim penghujan tiba. Telah diamati produksi listrik sebuah 4000 Wp PLTS rumahan selama kurang lebih satu tahun dari Oktober 2021 sampai Oktober 2022 penggunaan. Menggunakan data logger, Sistem hybrid on-grid dengan 4000 Wp didapati bahwa rata - rata produksi listrik tahunan adalah 427 kWh/bulan dan 14.2 kWh/hari. Produksi listrik paling tinggi terjadi pada bulan Januari 2022 sebesar 488.7 kWh/bulan dengan rata - rata harian 16.3 kWh/hari, sedangkan yang terendah terjadi pada bulan Oktober 2022 yaitu sebesar 293.5 kWh/bulan dengan rata - rata harian 9.8 kWh/hari. Pada musim penghujan 2021-2022 (sebelum bulan April 2022) tidak selalu hujan terjadi pada jam - jam produksi listrik, sehingga produksi listrik rata-rata tiap bulan dikisaran 12.8 - 16.3 kWh/hari masih dinilai cukup baik. Dari observasi, pada kondisi berawan (e.g. suasana redup akibat awan yang melintas) kapasitas PLTS dapat turun sampai up to 25% dari total kapasitas atau sekitar up to 1000 Watt. Pada kondisi mendung berat dan hujan lebat, produksi listrik solar panel sangat minimal bahkan tidak ada produksi listrik. Kondisi ideal produksi listrik adalah kondisi dimana suasana hari tidak terlalu berawan, tidak mendung dan tidak terjadi hujan. Jika kondisi ini terjadi, maka saat jam produksi prima (jam 10.00 - 14.00) efisiensi produksi listrik sekitar 75% dari total kapasitas 4000 Wp tercapai atau sekitar 3000 watt.

description: We present optical and near-infrared imaging of the field of the z=7.0842 quasar ULAS J112001.48+064124.3 taken with the Hubble Space Telescope. We use these data to search for galaxies that may be physically associated with the quasar, using the Lyman break technique, and find three such objects, although the detection of one in Spitzer Space Telescope imaging strongly suggests it lies at z~2. This is consistent with the field luminosity function and indicates that there is no excess of >L* galaxies within 1 Mpc of the quasar. A detection of the quasar shortward of the Ly-alpha line is consistent with the previously observed evolution of the intergalactic medium at z>5.5.

description: A first-principles study of the structural and electronic properies of carbon impurities in CuIn$_{1-x}$Ga$_x$Se$_{2}$ is presented. Carbon is present in organic molecules in the precursor solutions used in nonvacuum growth methods, making more efficient use of material, time and energy than traditional vacuum methods. The formation energies of several carbon impurities are calculated using the hybrid HSE06 functional. C$_{\mathrm{Cu}}$ acts as a shallow donor, C$_{\mathrm{In}}$ and interstitial C yield deep donor levels in CuInSe$_{2}$, while in CuGaSe$_{2}$ C$_{\mathrm{Ga}}$ and interstitial C act as deep amphoteric defects. So, if present, these defects reduce the majority carrier (hole) concentration by compensating the acceptor levels and become trap states for the photogenerated minority carriers (electrons). However, the formation energies of the calculated carbon impurities are high, even under C-rich growth conditions. Therefore, these impurities are not likely to form and will probably be expelled to the intergranular region and out of the absorber layer.

description: This study aims to evaluate the wound healing potential of lectin isolated from the seeds of Centrolobium microchaete (Mart. ex Benth) (CML) on cutaneous wounds in mice. CML did not show cytotoxicity on murine dermal fibroblasts (L929 cell line). The wounds treated with CML (200 μg/mL) showed a decrease in area within 12 days post-operative (P.O.) when compared to control. On 3rd and 7th day P.O., the CML-treated group exhibited fibroblast proliferation and neovascularization. On 12th day P.O., complete restructuring of the epithelial layer and connective tissue was observed in the CML-treated group, whereas control groups exhibited incomplete reepithelialization. CML treatment enhanced the wound closure via the wound contraction process, resulting in the restructuring of the skin layers on 12th day P.O. In conclusion, CML induced a fast and efficient wound healing, suggesting that it can be used as a promising therapeutic tool to heal acute wounds.

description: Chalcones (1,3-diphenylpropen-1-ones) are a class of flavonoids that have been shown a broad spectrum of biological activities with therapeutic potential. Naturally occurring chalcones or synthetic chalcone derivatives have been extensively investigated as anticancer compounds. Cancer is still among the leading causes of death globally, although cancer treatments have improved over the past decades. Most of chemotherapeutic drugs target proliferating tumor cells; however, the cancer cells capabilities are also associated to tumor surround microenvironment. Thereby, the search of new compounds with a broad antitumor activity is still a great challenge. The cytotoxicity mechanisms of chalcones are beyond apoptosis induction in tumor cells, which make them promising compound for cancer therapy. In this mini-review we summarized recent studies that describe the anticancer potential of chalcones related to some of hallmarks of cancer. We shed a light on sustaining proliferative signaling, tumor-promoting inflammation, activating invasion and metastasis, inducing angiogenesis and resisting cell death.

description: In this paper, we study various mixed state information theoretic quantities for a boosted black brane geometry. We have considered two setups, namely, a strip-like subsystem taken parallel and perpendicular to the direction of the boost. The quantities we calculate are the entanglement wedge cross-section, mutual information, entanglement negativity, and purification complexity. In the subsequent analysis, we have incorporated the thin-strip approximation and computed the leading order change (over pure AdS) in the concerned information theoretic quantities due to the boost parameter. We also show the relation of these quantities computed holographically to the energy and pressure of the boundary field theory. We then proceed to calculate the asymmetry ratios of these quantities, and observe that they are independent of the subsystem size. Finally, we proceed to study an interesting limit of the boosted black brane geometry, which is the so called AdS wave geometry. We once again compute all the mixed state information theoretic quantities for this geometry.

description: We propose a paradigmatic model system, a subcritical Hopf normal form subjected to noise and time-delayed feedback, to investigate the impact of time delay on coherence resonance in non-excitable systems. We develop analytical tools to estimate the stationary distribution and the time correlations in nonlinear stochastic delay differential equations. These tools are applied to our model to propose a novel quantity to measure coherence resonance induced by a saddle-node bifurcation of periodic orbits.

On Leray's problem in an infinite-long pipe with the Navier-slip boundary condition

description: The original Leray's problem concerns the well-posedness of weak solutions to the steady incompressible Navier-Stokes equations in a distorted pipe, which approach to the Poiseuille flow subject to the no-slip boundary condition at spacial infinity. In this paper, the same problem with the Navier-slip boundary condition instead of the no-slip boundary condition, is addressed. Due to the complexity of the boundary condition, some new ideas, presented as follows, are introduced to handle the extra difficulties caused by boundary terms. First, the Poiseuille flow in the semi-infinite straight pipe with the Navier-slip boundary condition will be introduced, which will be served as the asymptotic profile of the solution to the generalized Leray's problem at spacial infinity. Second, a solenoidal vector function defined in the whole pipe, satisfying the Navier-slip boundary condition, having the designated flux and equalling to the Poiseuille flow at large distance, will be carefully constructed. This plays an important role in reformulating our problem. Third, the energy estimates depend on a combined $L^2$ estimate of the gradient and the stress tensor of the velocity.

Gas accretion from minor mergers in local spiral galaxies
Creators: name: Di Teodoro, Enrico
name: Fraternali, Filippo
Publisher: name: arXiv
Year: 2014
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: In this paper we quantify the gas accretion rate from minor mergers onto star-forming galaxies in the Local Universe using HI observations of 148 nearby spiral galaxies (WHISP sample). We developed a dedicated code that iteratively analyses HI data-cubes, finds dwarf gas-rich satellites around larger galaxies and estimates an upper limit to the gas accretion rate. We found that 22% of the galaxies have at least one detected dwarf companion. We made the very stringent assumption that all satellites are going to merge in the shortest possible time transferring all their gas to the main galaxies. This leads to an estimate of the maximum gas accretion rate of 0.28 solar masses per year, about five times lower than the average SFR of the sample. Given the assumptions, our accretion rate is clearly an overestimate. Our result strongly suggests that minor mergers do not play a significant role in the total gas accretion budget in local galaxies.

description: Trifolium pratense, is a forage found worldwide, but it is negatively impacted by the clover root borer, Hylastinus obscurus. Methanolic extraction has been reported for isolating formononetin from vegetal tissues, with an antifeeding effect on H. obscurus. However, this methodology is time-consuming and also extracts other secondary metabolites, whereas enzymatic assays can provide higher specificity. Hence, the objective of this work was to determine the optimal conditions in pH, temperature, and incubation time for the activity of isoflavone synthase via a response surface model. Once these parameters were optimized, the concentration of formononetin in cultivars and experimental lines of T. pratense was evaluated enzymatically. The results showed that the best condition for developing the enzymatic assay was pH 9.1 with an incubation at 34.5 °C for 155 min. The formononetin content fluctuated between 0.74 and 1.96 mg/g of fresh weight, where Precoz-3, Precoz-1, and Superqueli-INIA presented the highest production.
First-principles study of the lattice instabilities in Mn$_{2}$Ni{\it X} ({\it X}= Al, Ga, In, Sn) magnetic shape memory alloys

description: Using first-principles based Density Functional Theory (DFT), we have investigated the structural instabilities in the austenite phases of Mn$_{2}$Ni{\it X} ({\it X}= Al, Ga, In, Sn) magnetic shape memory alloys (MSMA). A complete softening is observed in the acoustic TA$_{2}$ branches for all the materials along [$ξξ$0] directions leading to the instability in the austenite structure which effectively stabilizes into martensitic structure. The reasons behind this softening are traced back to the repulsion from the optical T$_{2g}$ branches and to the nesting features in the Fermi surfaces. The vibrational density of states, the force constants and the elastic moduli are also computed and analyzed, which reconfirm the underlying mechanism behind the instabilities. The results indicate that the phonon anomalies are related to the occurrence of possible pre-martensitic phases which can be quite complex.

Quantum Approximate Optimization Algorithm with Sparsified Phase Operator

description: The Quantum Approximate Optimization Algorithm (QAOA) is a promising candidate algorithm for demonstrating quantum advantage in optimization using near-term quantum computers. However, QAOA has high requirements on gate fidelity due to the need to encode the objective function in the phase separating operator, requiring a large number of gates that potentially do not match the hardware connectivity. Using the MaxCut problem as the target, we demonstrate numerically that an easier way to implement an alternative phase operator can be used in lieu of the phase operator encoding the objective function, as long as the ground state is the same. We observe that if the ground state energy is not preserved, the approximation ratio obtained by QAOA with such phase separating operator is likely to decrease. Moreover, we show that a better alignment of the low energy subspace of the alternative operator leads to better performance. Leveraging these observations, we propose a sparsification strategy that reduces the resource requirements of QAOA. We also compare our sparsification strategy with some other classical graph sparsification methods, and demonstrate the efficacy of our approach.

description: When a quantum field theory in $d$-spacetime dimensions possesses a global $(d-1)$-form symmetry, it can decompose into disjoint unions of other theories. This is reflected in the physical quantities of the theory and can be used to study properties of the constituent theories. In this note we highlight the equivalence between the decomposition of orbifold $σ$-models and disconnected McKay quivers. Specifically, we show in numerous examples that each component of a McKay quiver can be given definitive geometric meaning through the decomposition formulae. In addition, we give a purely group and representation theoretic derivation of the quivers for the cases where the trivially acting part of the orbifold group is central. As expected, the resulting quivers are compatible with the case of $σ$-models on `banded' gerbes.

description: The development of ICT has emerged a new way of learning using electronic platforms: E-learning. In addition, pedagogical approaches have been adopted in teaching based on group learning, such as the project-based teaching. The project-based teaching is an active learning method, based on group work to develop skills and acquire knowledge. However, the group of students is facing several challenges throughout the project, such as the decision-making group. The group decision generates convergences and divergences among members. Our approach in this article relates to the calculation of the homogeneity of a group of learners during decision making in an educational project.

description: In this work we present a hierarchical framework for solving discrete stochastic pursuit-evasion games (PEGs) in large grid worlds. With a partition of the grid world into superstates (e.g., "rooms"), the proposed approach creates a two-resolution decision-making process, which consists of a set of local PEGs at the original state level and an aggregated PEG at the superstate level. Having much smaller cardinality, both the local games and the aggregated game can be easily solved to a Nash equilibrium. To connect the decision-making at the two resolutions, we use the Nash values of the local PEGs as the rewards for the aggregated game. Through numerical simulations, we show that the proposed hierarchical framework significantly reduces the computation overhead, while still maintaining a satisfactory level of performance when competing against the flat Nash policies.

description: The methanolic extract of Mussaenda pubescens Dryand leaves exhibited significant anti-osteoclastogenic activity. Chemical investigation of M. pubescens led to the isolation of one new cycloartane saponin, mussaendoside X (1) along with eight known compounds: heinsiagenin A 3-O-[α-L-rhamnopyranosyl-(1→2)-O-β-D-glucopyranosyl-(1→2)]-O-β-D-glucopyranoside (2), mussaendoside O (3), heinsiagenin A 3-O-[α-L-rhamnopyranosyl-(1→2)-O-β-D-glucopyranosyl-(1→2)]-O-β-D-glucopyranosyl-(1→4)-O-β-D-glucopyranoside (4), mussaendoside G (5), mussaendoside U (6), shanzhiside methyl ester (7), barlerin (8) and musaenoside (9). Their structures were elucidated by extensive spectroscopic methods including 1D- and 2D-NMR as well as MS analysis and comparison with the literature. Cycloartane saponins 1–6 positively suppressed osteoclast formation in an anti-osteoclastogenic screening assay. Consequently, treatment of RANKL-stimulated RAW 264.7 cells with compounds 1–4 significantly decreased the number of osteoclasts in a concentration-dependent manner. Six compounds from M. pubescens, with the new cycloartane, mussaendoside X, were shown for the first time as potential effective inhibitors of osteoclastogenesis.

description: The possibility of integration of two important categories of optical components, i.e., circular polarizer and lens, into a thin plasmonic metasurface is examined. After exploring general theoretical formulation, optimal designs to realize polarizing lenses at mid-infrared frequencies are presented, for the cases when metal losses cannot be neglected. A two-dimensional array of Y-shaped nanoantennas with polarization dependent and spatially varying phase response is the basis for such a unique compact polarizing lens, whose properties can have a high impact in integrated optics.
Developing and testing measures of exchange market pressure for three emerging Asian economies
Creators: name: Deffenu, Elisa
Publisher: name: Loughborough University
Year: 2022
Subjects: Economics

description: This thesis uses the concept of exchange market pressure (EMP) - which is a measure of ex ante external imbalance in the foreign exchange market – to examine external disequilibrium in three emerging Asian economies, namely China, India and Vietnam, vis-a-vis the US Dollar over the last two decades. A new model of EMP is developed, which differs from previous measures in that we use a balance of payments model to derive a measure of exchange market pressure, rather than the traditional stock adjustment, money market model, explicitly allowing for imperfect capital mobility, which is important for our sample of countries. The new measure postulates that exchange market pressure can be explained by domestic and foreign incomes, real depreciation and the change in the short-term interest rate differential. The empirical analysis further extends the model to consider US central bank intervention, represented by a QE-adjusted measure of US policy stance, and domestic and US economic policy uncertainty (EPU). We find that in addition to the previous variables, US policy stance as well as EPU are significant drivers of EMP in China, India and Vietnam.

description: Reading can be considered constitutive epistemology for science and a fundamental aspect of scientific literacy. This study attempted to give further insights into the comprehension of different genres of science texts (textbook and popular science) and the assimilation of the academic language by adolescent age students. The writings 14- and 15-year-old students produced after reading one of these two genres were analysed while controlling for their reading skills and gender. The results indicated that popular science text readers achieved better comprehension scores for some of the ideas provided by the texts and that the performance of boys and girls reading the popular science materials tended to converge for most of the text ideas. Furthermore, analysis of some attributes of scientific writing revealed significant linguistic differences in the writings produced by the readers of different text genres. Data interpretation implies that (a) the influence of text genre on reading comprehension can be restrained only to some of the text imparted propositions; (b) certain school science text genres were prone to reverse the well-known girls’ reading superiority over boys; and (c) students can reproduce text characteristics in their writing that is more consistent with academic language. Overall, the findings presented favour a view that science reading is a complex phenomenon that merits more in-depth research.
The Metallicity Dependence of Giant Planet Incidence

Publisher: name: arXiv
Year: 2014
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We describe three corrections that should be applied to the observed relative incidence of nearby stars hosting giant planets. These are diffusion in the stellar atmosphere, use of the [Ref] index in place of [Fe/H] for metallicity, and correction for local sampling with the W velocity. We have applied these corrections to a subset of the SPOCS exoplanet survey with uniform giant planet detectability. Fitting the binned data to a power law of the form, $α10^{β[Fe/H]}$, we derived $α= 0.022 \pm 0.007$ and $β= 3.0 \pm 0.5$; this value of $β$ is 50\% larger than the value determined by \citet{fv05}. While the statistical significance of this difference is marginal, given the small number statistics, these corrections should be included in future analyses that include larger samples.

description: We develop the Morita theory of fusion 2-categories. In order to do so, we begin by proving that the relative tensor product of modules over a separable algebra in a fusion 2-category exists. We use this result to construct the Morita 3-category of separable algebras in a fusion 2-category. Then, we go on to explain how module 2-categories form a 3-category. After that, we define separable module 2-categories over a fusion 2-category, and prove that the Morita 3-category of separable algebras is equivalent to the 3-category of separable module 2-categories. As a consequence, we show that the dual tensor 2-category with respect to a separable module 2-category, that is the associated 2-category of module 2-endofunctors, is a multifusion 2-category. Finally, we give three equivalent characterizations of Morita equivalence between fusion 2-categories.

description: Glycyrrhiza glabra roots have been well studied for their pharmacological activities, whereas less research has been conducted on liquorice aerial parts. Leaves represent a good source of D-pinitol, useful in the treatment of insulin resistance-related pathologies. Herein, we analyzed the in vitro effects of a D-pinitol-rich methanolic extract from Glycyrrhiza glabra leaves (GGLME) against lipotoxicity-related hypertrophy, inflammation, and insulin resistance in 3T3-L1 adipocytes exposed to palmitic acid (PA), comparing its activity with D-pinitol. GGLME pretreatment decreased lipid deposition, PPAR-γ, and NF-κB pathway induced by PA, similarly to D-pinitol, and improved insulin sensitivity, in presence or not of PA, increasing PI3K, pAkt, and GLUT1 levels. This study confirms that liquorice leaves, considered a waste of resource, could potentially be reused, and support further in vivo studies on animal and human models. In conclusion, liquorice leaves extract represents a potential candidate for prevention of metabolically induced inflammation, frequently leading to metabolic disorders.
