description: We give a short summary of results and conjectures in the theory of dynamical quantum group related to the dynamical coboundary equation also known as IRF-Vertex transform. O.Babelon has shown that the dynamical twist $F(x)$ of $U_q(sl(2))$ is a dynamical coboundary $M(x)$ i.e $F(x)M_1(xq^{h_2})M_2(x)=Δ(M(x)).$ We give a new formula for this element $M(x)$ as an infinite product and give a new proof of the coboundary relation. Our proof involves the quantum Weyl group element, giving possible hint for the generalization to higher rank case.

description: Recent simulation results imply the lowering of the ground-state correlation energy per counterion at a charged planar wall, compared with that of the 2D and 3D one-component plasma systems. Our aim is to correctly evaluate the ground-state energy of strongly-coupled counterion systems by considering a quasi-2D bound state where bound counterions are confined to a layer of molecular thickness. We use a variational approach based on the Gibbs-Bogoliubov inequality for the lower-bound free energy so that the liquid-state theory can be incorporated into the formulations. The soft mean spherical approximation demonstrates that the lowered ground-state energy can be reproduced by the obtained analytical form of a quasi-2D bound state.

description: This paper presents Dual Action Policy (DAP), a novel approach to address the dynamics mismatch inherent in the sim-to-real gap of reinforcement learning. DAP uses a single policy to predict two sets of actions: one for maximizing task rewards in simulation and another specifically for domain adaptation via reward adjustments. This decoupling makes it easier to maximize the overall reward in the source domain during training. Additionally, DAP incorporates uncertainty-based exploration during training to enhance agent robustness. Experimental results demonstrate DAP's effectiveness in bridging the sim-to-real gap, outperforming baselines on challenging tasks in simulation, and further improvement is achieved by incorporating uncertainty estimation.

description: Currently, reliable and accurate ship detection in optical remote sensing images is still challenging. Even the state-of-the-art convolutional neural network (CNN) based methods cannot obtain very satisfactory results. To more accurately locate the ships in diverse orientations, some recent methods conduct the detection via the rotated bounding box. However, it further increases the difficulty of detection, because an additional variable of ship orientation must be accurately predicted in the algorithm. In this paper, a novel CNN-based ship detection method is proposed, by overcoming some common deficiencies of current CNN-based methods in ship detection. Specifically, to generate rotated region proposals, current methods have to predefine multi-oriented anchors, and predict all unknown variables together in one regression process, limiting the quality of overall prediction. By contrast, we are able to predict the orientation and other variables independently, and yet more effectively, with a novel dual-branch regression network, based on the observation that the ship targets are nearly rotation-invariant in remote sensing images. Next, a shape-adaptive pooling method is proposed, to overcome the limitation of typical regular ROI-pooling in extracting the features of the ships with various aspect ratios. Furthermore, we propose to incorporate multilevel features via the spatially-variant adaptive pooling. This novel approach, called multilevel adaptive pooling, leads to a compact feature representation more qualified for the simultaneous ship classification and localization. Finally, detailed ablation study performed on the proposed approaches is provided, along with some useful insights. Experimental results demonstrate the great superiority of the proposed method in ship detection.

description: Phasor Measurement Unit measurement data have been widely used in nowadays power system applications both in steady state and dynamic analysis. The performance of these applications running in utilities' energy management system depends heavily on an accurate positive sequence power system model. However, it is impractical to find this accurate model with transmission line parameters calculated directly with the PMU measurements due to ratio errors brought by instrument transformers and communication errors brought by PMUs. Therefore, a methodology is proposed in this paper to estimate the actual transmission lines parameters throughout the whole system and, at the same time, calibrate the corresponding instrument transformers. A PMU positive sequence measurement error model is proposed targeting at the aforementioned errors, which is applicable to both transposed and un-transposed transmission lines. A single line parameters estimation method is designed based on Least Squares Estimation and this error model. This method requires only one set of reference measurements and the accuracy can be propagated throughout the whole network along with the topology acquired by the introduced Edge-based Breadth-first Search algorithm. The IEEE 118-bus system and the Texas 2000-bus system are used to demonstrate the effectiveness and efficiency of the proposed method. The potential for deployment in reality is also discussed.

description: We numerically study the non-equilibrium dynamics of the three dimensional Heisenberg Edwards-Anderson spin glass following a sudden quench to its low temperature phase. The subsequent aging behavior of the system is analyzed in detail, and the scaling behavior of various space-time correlation functions is investigated for both spin and chiral degrees of freedom. We carefully compare our results with those obtained from simulations of the more studied Ising version of the model, and with experiments on real spin glasses in which the spins have vectorial character. Finally, the present dynamical study offers new perspectives into the possibility of spin-chirality decoupling at low temperature in vectorial spin glasses.

description: Purpose. The purpose of the study is to review and summarise the views on the evaluation of modern methods and approaches to the determination of the economic efficiency of milk production. Methodology / approach. Analysis of literary sources, critical assessment of different views in terms of assessment of milk production efficiency and development of own proposal in terms of this assessment were selected as the study method. Results. It has been established that for the diary livestock sector, the most common practice of assessing economic efficiency is through the calculation of gross production per 1 average annual animal head, 1 man-hour, 1 centner of feed unit, UAH 1 of feed costs, UAH 1 of expenses; gross income per 1 head, per 1 man-hour; net income per 1 head, 1 man-hour, UAH 1 expenses; level of profitability and labour expense; productivity of cattle and poultry. It is stated that Ukraine has an urgent problem of raising the level of economic efficiency of milk production. It is noted that the unprofitableness of the livestock sector over a considerable period of time is one of the main factors in reducing both the livestock and the volumes of milk production. Originality / scientific novelty. In order to assess the level of efficiency in dairy farming, it is proposed to calculate relative efficiency factor of expenditure in livestock sector. This parameter evaluates the ratio of changes in the rate of production of consumable products (animal productivity) per one head of an animal with a change in the rate of expenditure. Its economic content is that when this factor is equal to 1, this suggests that the rate of change in expenses and resulting income, or productivity at the enterprise, coincide. If it is higher than 1, then there is an increasing return, and if lower than 1 – decreasing return. Practical value / implications. Under current conditions, development of the livestock sector is possible only under the conditions of the existence of an appropriate economic incentive mechanism for manufacturers, including state support through appropriate programs. This would allow enterprises to invest in the initial stages of production.

description: Growing model complexities in load modeling have created high dimensionality in parameter estimations, and thereby substantially increasing associated computational costs. In this paper, a tensor-based method is proposed for identifying composite load modeling (CLM) parameters and for conducting a global sensitivity analysis. Tensor format and Fokker-Planck equations are used to estimate the power output response of CLM in the context of simultaneously varying parameters under their full parameter distribution ranges. The proposed tensor structured is shown as effective for tackling high-dimensional parameter estimation and for improving computational performances in load modeling through global sensitivity analysis.

description: Efforts to combine the advantages of multiple systems to enhance functionlities through solid solution design present a great challenge due to the constraint imposed by the classical Vegard law. Here, we successfully navigate this trade off by leveraging the synergistic effect of chemical doping and strain engineering in solid solution system of BiFeO3 BaTiO3. Unlike bulks, a significant deviation from the Vegard law accompanying with enhanced multiferroism is observed in the strained solid solution epitaxial films, where we achieve a pronounced tetragonality, enhanced saturated magnetization, substantial polarization, high ferroelectric Curie temperature, all while maintaining impressively low leakage current. These characteristics surpass the properties of their parent BiFeO3 and BaTiO3 films. Moreover, the superior ferroelectricity has never been reported in corresponding bulks. These findings underscore the potential of strained BiFeO3 BaTiO3 films as lead-free, room-temperature multiferroics.

description: Purpose. The purpose of the article is to analyze the background of the creation of family-type farms based on personal peasant farms, to consider possible scenarios for the development of such processes in Ukraine, to identify the strategic objectives of the development of small entrepreneurship in rural areas and the main ways of achieving them. Methodology / method / approach. The theoretical and methodological basis of the research is the dialectical method of knowledge of economic processes, the fundamental provisions of modern economic theory, legislative acts of Ukraine, scientific works of domestic and foreign scientists on trends and specifics of small business development in rural areas. To achieve the goal, there were used methods of logical generalization and systematization; abstract method; techniques of analogy and comparison. Results. The results of the analysis of the background of the establishment of family-type farms based on personal peasant farms indicate a significant untapped potential in Ukraine. The implementation of this process will be facilitated by the availability of labor, natural resources and favorable agro-climatic conditions, as well as the growth of demand for traditional and organic food. Scenarios of possible development of small entrepreneurship in rural areas are considered; and it is considered more acceptable one that involves the support of small business entities and developing market infrastructure for expanding the range of agricultural products and foodstuffs, increasing their production volumes, and improving their quality. The strategic goals of small business development in rural areas and the main ways of their achievement are determined. Originality / scientific novelty. For the first time a SWOT-analysis of the development of small business in rural areas of Ukraine was conducted and three alternative scenarios of possible development of such entrepreneurship in the countryside were considered. The main ways to achieve the identified strategic goals are to create a favorable tax, financial microclimate for the activity of small forms of entrepreneurship in rural areas and the development of the infrastructure of the agrarian market. Practical value / significance. Recommendations for the preparation of regional agro-industrial development programs and rural areas are given. Among the strategic objectives of the regional agro-industrial development and rural development programs, it is proposed to foresee the expansion of the entrepreneurial environment in the village and the development of the activity of agricultural service cooperatives.

description: A comprehensive study was conducted to determine thorium, uranium and potassium elemental concentrations in surface soils throughout the accessible area of Cyprus using high-resolution gamma-ray spectrometry. A total of 115 soil samples was collected from all over the bedrock surface of the island based on the different lithological units of the study area. The soil samples were sieved through a fine mesh, sealed in 1000-mL plastic Marinelli beakers, and measured in the laboratory in terms of their gamma radioactivity for a counting time of 18 hours each. From the measured gamma-ray spectra, elemental concentrations were determined for thorium (range from 2.5x10^-3 to 9.8 micro g g-1), uranium (from 8.1x10^-4 to 3.2 micro g g-1) and potassium (from 1.3x10^-4 to 1.9 %). The Arithmetic mean values (A.M. +- S.D.) calculated are (1.2 +- 1.7) micro g g-1, (0.6 +- 0.7) micro g g-1, and (0.4 +- 0.3) %, for thorium, uranium and potassium, respectively, which are by a factor of three to six lower than the world average values of 7.4 micro g g-1 (Th), 2.8 micro g g-1 (U) and 1.3 % (K) derived from all data available worldwide. The best-fitting relation between the concentrations of Th and K versus U, and also of K versus Th, is essentially of linear type with a correlation coefficient of 0.93, 0.84, and 0.90, respectively. The Th/U, K/U, and K/Th ratios (slopes) calculated are equal to 2.0, 2.8x10^3,and 1.4x10^3, respectively.

description: We study the problem of unbiased estimation of expectations with respect to (w.r.t.) $π$ a given, general probability measure on $(\mathbb{R}^d,\mathcal{B}(\mathbb{R}^d))$ that is absolutely continuous with respect to a standard Gaussian measure. We focus on simulation associated to a particular class of diffusion processes, sometimes termed the Schrödinger-Föllmer Sampler, which is a simulation technique that approximates the law of a particular diffusion bridge process $\{X_t\}_{t\in [0,1]}$ on $\mathbb{R}^d$, $d\in \mathbb{N}_0$. This latter process is constructed such that, starting at $X_0=0$, one has $X_1\sim π$. Typically, the drift of the diffusion is intractable and, even if it were not, exact sampling of the associated diffusion is not possible. As a result, \cite{sf_orig,jiao} consider a stochastic Euler-Maruyama scheme that allows the development of biased estimators for expectations w.r.t.~$π$. We show that for this methodology to achieve a mean square error of $\mathcal{O}(ε^2)$, for arbitrary $ε>0$, the associated cost is $\mathcal{O}(ε^{-5})$. We then introduce an alternative approach that provides unbiased estimates of expectations w.r.t.~$π$, that is, it does not suffer from the time discretization bias or the bias related with the approximation of the drift function. We prove that to achieve a mean square error of $\mathcal{O}(ε^2)$, the associated cost is, with high probability, $\mathcal{O}(ε^{-2}|\log(ε)|^{2+δ})$, for any $δ>0$. We implement our method on several examples including Bayesian inverse problems.

Year: 2014

description: The purpose of this paper is to explore what research says about the effectiveness of using picture books to support language acquisition among students learning English as a second language. The research can be grouped into the following themes : book floods, the effect of using picture books on a specific ability or skill and wordless picture books. Researchers "flooded" communities in the South pacific and China with high interest western picture books and examined the effect that those picture books had on different learning outcomes related to story structure, oral language and reading comprehension. Other experimental research sought to compare the effects of a book based program as opposed to the use of an audio-lingual highly structured textbook. Lastly, some of the research revolved around case studies or experimental studies on how wordless books can be used to promote language learning. Communities who were exposed to picture books showed significant improvement in oral language, comprehension and use of story structure elements. Other research that was conducted comparing the use of picture books to highly structured texts or exercises found that there was a significant increase in language comprehension, vocabulary and expression when using picture books. Wordless books were also found to be an excellent resource for facilitating language development in students learning English as a second language. In my Connections to Practice section I propose a unit plan created using the different picture book versions of the 3 Little Pigs with my English language learners. In this unit students will study and explore variations in the 3 Little Pigs and will participate in activities designed to enhance their language acquisition.

description: The search for a Dark Matter particle is the new grail and hard-sought nirvana of the particle physics community. From the theoretical side, it is the main challenge to provide a consistent and model-independent tool for comparing the bounds and reach of the diverse experiments. We propose a first complete classification of minimal consistent Dark Matter models, which provides the missing link between experiments and top-down models. Consistency is achieved by imposing renormalisability and invariance under the full Standard Model symmetries. We apply this paradigm to fermionic Dark multiplets with up to one mediator. We also reconsider the one-loop contributions to direct detection, including the relevant effect of (small) mass splits in the Dark multiplet. Our work highlights the presence of unexplored viable models, and paves the way for the ultimate systematic hunt for the Dark Matter particle.

Economic and statistical methods (graphic method, comparison method, correlation-regression and trend analysis) were used to diagnose the development trends of the global agricultural market. Using techniques of abstract-logical method and method of generalization, the main regularities of the manifestation of globalization in the agrarian sector were identified and the priorities of ensuring the competitiveness of Ukraine’s agriculture were determined. Results. In the article, according to the analysis results of the world agrarian market development, it was concluded that there is a trend towards its growth. There is also a tendency towards concentration of agricultural products world trade by individual groups of countries. That is why the strategy of promoting Ukrainian agricultural goods to world markets should be moderately aggressive, and strengthen the position of Ukrainian agriculture in world markets requires the implementation of priorities ensuring its competitiveness. Originality / scientific novelty. The set of priorities for ensuring the Ukraine’s agriculture competitiveness in the world markets was improved. These priorities are systematized in two groups: market oriented priorities (formation of an export-oriented model of agricultural development, moderately aggressive character of Ukrainian goods promotion, providing of complementary effects of entering the world markets, creation of new non-traditional market niches, market orientation of positioning strategies and promotion of goods) and production oriented priorities (providing innovative way of business, the integration of producers in the export-oriented segment, the development of organic products production, etc.). Practical value / significance. Determining the priorities of ensuring Ukraine’s agriculture competitiveness will allow to substantiate the methods and mechanisms of policy implementation to strengthen its positions in the world agrarian markets.

description: We propose a scalable readout interface for superconducting nanowire single-photon detector (SSPD) arrays, which we call the AQFP/RSFQ interface. This interface is composed of adiabatic quantum-flux-parametron (AQFP) and rapid single-flux-quantum (RSFQ) logic families. The AQFP part reads out the spatial information of an SSPD array via a single cable, and the RSFQ part reads out the temporal information via a single cable. The hybrid interface has high temporal resolution owing to low timing jitter in the operation of the RSFQ part. In addition, the hybrid interface achieves high circuit scalability because of low supply current in the operation of the AQFP part. Therefore, the hybrid interface is suitable for handling many-pixel SSPD arrays. We demonstrate a four-pixel SSPD array using the hybrid interface as proof of concept. The measurement results show that the hybrid interface can read out all of the pixels with a low error rate and low timing jitter.

description: Analyzing data from GLAST's Large Area Telescope (LAT) will require sophisticated techniques. The PSF and effective area are functions of both photon energy and the position in the field-of-view. During most of the mission the observatory will survey the sky continuously and thus the LAT will detect each count from a source at a different detector orientation; each count requires its own response function! The likelihood as a function of celestial position and photon energy will be the foundation of the standard analysis techniques. However the 20 MeV-300 GeV emission at the time of the ~100 keV burst emission (timescale of ~10 s) can be isolated and analyzed because essentially no non-burst counts are expected within a PSF radius of the burst location during the burst. Both binned and unbinned (in energy) spectral fitting will be possible. Longer timescale afterglow emission will require the likelihood analysis that will be used for persistent sources.

description: In this report, we describe the proximity effect which arises when a quasicrystal is placed in contact with a superconductor. We consider the simplest known model of a quasicrystal, the 1D Fibonacci chain, for which all states are known to be critical. A hybrid ring is made by connecting a finite piece of such a Fibonacci chain to a BCS-type superconductor. Solving the resulting Bogoliubov-de Gennes equations self-consistently, we show that the proximity effect in the Fibonacci chain is long ranged, and that the induced superconducting order carries information on topological properties, namely, the winding numbers of edge states of the Fibonacci chain.

AbstractMelphalan flufenamide (melflufen, Pepaxto®) is a peptide conjugated alkylating drug developed by Oncopeptides for the treatment of multiple myeloma (MM) and amyloid light-chain amyloidosis. It is an ethyl ester of a lipophilic dipeptide consisting of melphalan and para-fluoro-L-phenylalanine. Due to its lipophilicity, melphalan flufenamide is rapidly transported across the cell membrane and almost immediately hydrolyzed by aminopeptidases in the cytoplasm to yield more hydrophilic alkylating molecules, such as melphalan and desethyl-melflufen. Like other nitrogen mustard drugs, melphalan flufenamide exerts antitumor activity through DNA crosslinking. In February 2021, melphalan flufenamide, in combination with dexamethasone, received its first approval in the USA for the treatment of adults with relapsed or refractory (r/r) MM who have received at least four prior lines of therapy and whose disease is refractory to at least one proteasome inhibitor (PI), one immunomodulatory agent, and one CD38-directed monoclonal antibody. A multinational clinical study of melphalan flufenamide in amyloid light-chain amyloidosis is underway across several countries, and preclinical studies for various haematological and solid cancers are underway. This article summarizes the milestones in the development of melphalan flufenamide leading to this first approval.

description: Indonesia began to grow oil palm in small scale in 1911. In 2006, palm oil production ranked first in the world. In 2007, the oil palm harvest area ranked first in the world. In 2009, the output of oil palm fruit ranked first in the world. To further explore the development prospects of the oil palm industry in Indonesia, the development of the oil palm industry in Indonesia is discussed, and the oil palm harvested area and yield and palm oil production in Indonesia are analyzed in this paper. The results showed that the oil palm harvested area in Indonesia showed an increasing trend from 1980 to 2016. During the period from 1980 to 1993, the oil palm harvested area was slowly increasing. In 2002-2016, the oil palm harvested area was growing rapidly, and the oil palm harvested area was 9.33 million ha in 2016. The growth trend of the oil palm fruit production was obvious in 2008-2016, and the oil palm fruit yield was 161.4 million t in 2016. The palm oil production increased slowly from 1980 to 1999. During the period 2000-2014, the palm oil production increased by a large margin. In 2014, the palm oil production was 29.28 million t. It is believed that the area of oil palm in Indonesia will continue to expand, and there is a development space of at least 1 500 000 to 2 000 000 ha. The oil palm fruit production and palm oil production in Indonesia will continue to increase in the coming years. Indonesia has unique advantages for the development of oil palm industry, with great potential for development.

description: The COVID-19 pandemic led to the adoption of severe measures to counteract the spread of the infection. Social distancing and lockdown measures modifies people's habits, while the Internet gains a major role to support remote working, e-teaching, online collaboration, gaming, video streaming, etc. All these sudden changes put unprecedented stress on the network. In this paper we analyze the impact of the lockdown enforcement on the Politecnico di Torino campus network. Right after the school shutdown on the 25th of February, PoliTO deployed its own in-house solution for virtual teaching. Ever since, the university provides about 600 virtual classes daily, serving more than 16,000 students per day. Here, we report a picture of how the pandemic changed PoliTO's network traffic. We first focus on the usage of remote working and collaborative platforms. Given the peculiarity of PoliTO in-house online teaching solution, we drill down on it, characterizing both the audience and the network footprint. Overall, we present a snapshot of the abrupt changes on campus traffic and learning due to COVID-19, and testify how the Internet has proved robust to successfully cope with challenges and maintain the university operations.

description: We present model spectral energy distributions, colors, polarization, and images for an evolutionary sequence of a low-mass protostar from the early collapse stage (Class 0) to the remnant disk stage (Class III). We find a substantial overlap in colors and SEDs between protostars embedded in envelopes (Class 0-I) and T Tauri disks (Class II), especially at mid-IR wavelengths. Edge-on Class I-II sources show double-peaked spectral energy distributions, with a short-wavelength hump due to scattered light and the long-wavelength hump due to thermal emission. These are the bluest sources in mid-IR color-color diagrams. Since Class 0 and I sources are diffuse, the size of the aperture over which fluxes are integrated has a substantial effect on the computed colors, with larger aperture results showing significantly bluer colors. This causes overlap in color-color diagrams between all evolutionary states, especially in the mid-IR. However the near-IR polarization of the Class 0 sources is much higher than the Class I-II sources, providing a means to separate these evolutionary states. We varied the grain properties in the circumstellar envelope, allowing for larger grains in the disk midplane and smaller in the envelope. We find that grain growth in disks of Class I sources can be detected at wavelengths greater than 100 $μ$m. Our image calculations predict that the diffuse emission from edge-on Class I and II sources should be detectable in the mid-IR with the Space Infrared Telescope Facility (SIRTF) in nearby star forming regions (out to several hundred parsecs).

description: We study the behavior of spatially homogeneous brane-worlds close to the initial singularity in the presence of both local and nonlocal stresses. It is found that the singularity in these brane-worlds can be locally either isotropic or anisotropic. We then investigate the Weyl curvature conjecture, according to which some measure of the Weyl curvature is related to a gravitational entropy. In particular, we study the Weyl curvature conjecture on the brane with respect to the dimensionless ratio of the Weyl invariant and the Ricci square and the measure proposed by Grøn and Hervik. We also argue that the Weyl curvature conjecture should be formulated on brane (i.e., in the four-dimensional context).

description: Based on survey data of 9 poverty-stricken counties in Wumen mountainous area, using the ordinal Probit model, this paper analyzed the influence mechanism for the assessment of the implementation effect of the policy of relocating the poor. It obtained the following results. (i) Material security and social environment have a positive influence on the assessment of the policy of relocating the poor. (ii) In terms of material security, there is no significant relationship between the employment environment and the assessment of the policy of relocating the poor. Per capita annual income, per capita housing, income-increasing channels, and endowment insurance have significant effects on the assessment of the policy of relocating the poor. (iii) In social environment, public services, infrastructure, neighborhood relations, and environmental sanitation have significant effects on the assessment of the policy of relocating the poor, while there is no significant relationship between the awareness of poverty alleviation policies and the effect assessment of the policy of relocating the poor. (iv) The severer the poverty, the more significant the assessment of the implementation effect of the policy of relocating the poor. In accordance with the above results, it came up with recommendations for targeted poverty alleviation.
