description: In this paper we demonstrate methods for reliable and efficient training of discrete representation using Vector-Quantized Variational Auto-Encoder models (VQ-VAEs). Discrete latent variable models have been shown to learn nontrivial representations of speech, applicable to unsupervised voice conversion and reaching state-of-the-art performance on unit discovery tasks. For unsupervised representation learning, they became viable alternatives to continuous latent variable models such as the Variational Auto-Encoder (VAE). However, training deep discrete variable models is challenging, due to the inherent non-differentiability of the discretization operation. In this paper we focus on VQ-VAE, a state-of-the-art discrete bottleneck model shown to perform on par with its continuous counterparts. It quantizes encoder outputs with on-line $k$-means clustering. We show that the codebook learning can suffer from poor initialization and non-stationarity of clustered encoder outputs. We demonstrate that these can be successfully overcome by increasing the learning rate for the codebook and periodic date-dependent codeword re-initialization. As a result, we achieve more robust training across different tasks, and significantly increase the usage of latent codewords even for large codebooks. This has practical benefit, for instance, in unsupervised representation learning, where large codebooks may lead to disentanglement of latent representations.

description: Neste artigo, procura-se abordar a recepção crítica à atuação literária do romancista José de Alencar, focando sua obra regionalista O Gaúcho, de 1870, por meio de um conjunto de cartas do português José Feliciano de Castilho, assinadas com o pseudônimo de Cincinato, que foram publicadas na imprensa do Rio de Janeiro, em 1871. As cartas, um gênero de texto comum na imprensa daquele período, foram veiculadas na revista Questões do Dia: observações políticas e literárias escritas por vários e coordenadas por Lucio Quinto Cincinato, sendo, em seguida, reunidas em livro homônimo. Ater-nos-emos àquelas de teor literário originadas da pena de Cincinato e escritas como instrumento político de censura e deslegitimação da prática literária e política de Alencar, que se posicionava, no momento, em confronto direto com o poder imperial, do qual Castilho era aliado.

description: This paper presents a novel and direct approach to price boundary and final-value problems, corresponding to barrier options, using forward deep learning to solve forward-backward stochastic differential equations (FBSDEs). Barrier instruments are instruments that expire or transform into another instrument if a barrier condition is satisfied before maturity; otherwise they perform like the instrument without the barrier condition. In the PDE formulation, this corresponds to adding boundary conditions to the final value problem. The deep BSDE methods developed so far have not addressed barrier/boundary conditions directly. We extend the forward deep BSDE to the barrier condition case by adding nodes to the computational graph to explicitly monitor the barrier conditions for each realization of the dynamics as well as nodes that preserve the time, state variables, and trading strategy value at barrier breach or at maturity otherwise. Given these additional nodes in the computational graph, the forward loss function quantifies the replication of the barrier or final payoff according to a chosen risk measure such as squared sum of differences. The proposed method can handle any barrier condition in the FBSDE set-up and any Dirichlet boundary conditions in the PDE set-up, both in low and high dimensions.

description: We prove the first genuine QBF proof size lower bounds for the proof system Merge Resolution (MRes [Olaf Beyersdorff et al., 2020]), a refutational proof system for prenex quantified Boolean formulas (QBF) with a CNF matrix. Unlike most QBF resolution systems in the literature, proofs in MRes consist of resolution steps together with information on countermodels, which are syntactically stored in the proofs as merge maps. As demonstrated in [Olaf Beyersdorff et al., 2020], this makes MRes quite powerful: it has strategy extraction by design and allows short proofs for formulas which are hard for classical QBF resolution systems.
 Here we show the first genuine QBF exponential lower bounds for MRes, thereby uncovering limitations of MRes. Technically, the results are either transferred from bounds from circuit complexity (for restricted versions of MRes) or directly obtained by combinatorial arguments (for full MRes). Our results imply that the MRes approach is largely orthogonal to other QBF resolution models such as the QCDCL resolution systems QRes and QURes and the expansion systems $\forall$Exp+Res and IR.

description: The Minimum Linear Arrangement problem (MLA) consists of finding a mapping $π$ from vertices of a graph to distinct integers that minimizes $\sum_{\{u,v\}\in E}|π(u) - π(v)|$. In that setting, vertices are often assumed to lie on a horizontal line and edges are drawn as semicircles above said line. For trees, various algorithms are available to solve the problem in polynomial time in $n=|V|$. There exist variants of the MLA in which the arrangements are constrained. Iordanskii, and later Hochberg and Stallmann (HS), put forward $O(n)$-time algorithms that solve the problem when arrangements are constrained to be planar (also known as one-page book embeddings). We also consider linear arrangements of rooted trees that are constrained to be projective (planar embeddings where the root is not covered by any edge). Gildea and Temperley (GT) sketched an algorithm for projective arrangements which they claimed runs in $O(n)$ but did not provide any justification of its cost. In contrast, Park and Levy claimed that GT's algorithm runs in $O(n \log d_{max})$ where $d_{max}$ is the maximum degree but did not provide sufficient detail. Here we correct an error in HS's algorithm for the planar case, show its relationship with the projective case, and derive simple algorithms for the projective and planar cases that run without a doubt in $O(n)$ time.
description: Here we have corrected a mistake we made in the previous version. In particular, line 7 of Algorithm 3.2 used to say: "For i = 1 to |C_v| ..."; it should be "For i = 2 to |C_v| ..." (notice the change from 'i=1' to 'i=2')

Due to the high level of suspended solute in SW and high level of iron in GW, both water sources qualified as below requirements for drinking water. As a solution, people in West Kalimantan preferred rainwater (RW) as a source of clean water and drinking water. However, the RW quality in West Kalimantan is decreasing due to increased population and economic activities. The increase in air pollution in the dry season also contributes to the decline in RW quality and raises health issues when used as the source of clean water. In slum areas in West Kalimantan, the RW harvesting system commonly used is Roof-Harvested Rainwater (RHRW) without additional treatment, increasing the potential for disease. Based on the problems above, this research aims to design a minimum and simple RW harvesting system to be applied to slum areas. The methods used in this study are field studies in three sub-districts (Tambelan Sampit, Sungai Jawi Luar, and Tengah) in Pontianak City, West Kalimantan, and Life Cycle Assessment (LCA) for design. The result of the study showed that communal RWHS are the most suitable design for slum areas. Also, in this study, we present the minimum and simple communal RWHS design results.

description: We investigate the possibility of forcing a self-supervised model trained using a contrastive predictive loss to extract slowly varying latent representations. Rather than producing individual predictions for each of the future representations, the model emits a sequence of predictions shorter than that of the upcoming representations to which they will be aligned. In this way, the prediction network solves a simpler task of predicting the next symbols, but not their exact timing, while the encoding network is trained to produce piece-wise constant latent codes. We evaluate the model on a speech coding task and demonstrate that the proposed Aligned Contrastive Predictive Coding (ACPC) leads to higher linear phone prediction accuracy and lower ABX error rates, while being slightly faster to train due to the reduced number of prediction heads.

description: We present a number of low-resource approaches to the tasks of the Zero Resource Speech Challenge 2021. We build on the unsupervised representations of speech proposed by the organizers as a baseline, derived from CPC and clustered with the k-means algorithm. We demonstrate that simple methods of refining those representations can narrow the gap, or even improve upon the solutions which use a high computational budget. The results lead to the conclusion that the CPC-derived representations are still too noisy for training language models, but stable enough for simpler forms of pattern matching and retrieval.

description: In the framework of the COASTAL project, at the Soil and Water Conservation Research group of the Spanish Research Council (CEBAS-CSIC), we organised six stakeholder workshops with representatives from agriculture, tourism, fisheries and salt pans, local population, public administrations, research and environmental NGOs and consultancies. During each of these workshops stakeholders jointly developed mental maps of the functioning of the socio-ecosystem of the Mar Menor coastal lagoon and its surrounding Campo de Cartagena. The methodology applied in the workshop fostered ‘Systems Thinking’ and helped to develop Causal Loop Diagrams (CLD). After the workshops, the six sectoral CLD were merged into one CLD describing all interactions mentioned by the stakeholders. This CLD was then presented and discussed with representatives of all sectors in a multi-actor workshop. Stakeholders also identified direction and weights of interactions that helped convert the CLD into Fuzzy Cognitive Maps. The weights were divided in high (1), medium (0.67) and low impact (0.33) of one variable on another. Fuzzy Cognitive Mapping was used to illustrate the impacts of different scenarios of implementation of individual or multiple solutions. This last step was performed in R script using FCMapper.

description: Este trabalho se insere na Análise do Discurso de linha francesa. Seu objetivo é apresentar uma concepção de Literatura como ‘instituição discursiva’ e discutir a problemática de (des)legitimação no ‘campo literário’. Esse campo se mostra como um lugar de poder em que diferentes enunciadores se colocam em concorrência por um ‘posicionamento’ mais ou menos legitimado. Para exemplificar a tentativa de (auto)legitimação por parte de um autor, recorremos a um trabalho de Maingueneau (2010), em que ele toma o percurso literário do poeta francês Émile Du Tiers. Veremos que, apesar das tentativas do poeta de se alinhar aos produtores parisienses de ‘centro’, ao fim de sua carreira, ele é ‘posicionado’ pela crítica como um escritor ‘regional’. Esses conceitos serão aqui trabalhados a partir de Maingueneau (2006, 2010).

description: The organic dye is one of the most problematic water pollutants in the vicinity of leather and textile industries. Adsorption method via functional materials can be considered as an effective method for dye removal from wastewater. In present work, the synthesis of mesoporous silica nanoparticles (MSNs) functionalised with histidine (MSN-His) has been reported for simultaneous removal of methylene blue (MB) and phenol red (PR) from an aqueous solution. The properties of nanoparticles were characterised in terms of size, surface area and surface modification using a scanning electron microscope (SEM), transmission electron microscope (TEM) and Fourier transform infrared (FT-IR). The influence of various factors including the contact time, the initial concentration of the adsorbate and pH of the medium on the MB and PR adsorption efficiencies were investigated. The maximum adsorption capacity was calculated to be ca. 65 mg/g for MB in basic media, and ca. 55 mg/g for PR in acidic media. The adsorption isotherm is fitted with Freundlich for all solutions. The maximum removal efficiency was ca. 70% for MB in basic media and PR in acidic media after second cycle.

description: Aiming at the problem that delay time is difficult to determine and prediction accuracy is low in building prediction model of SCR system, a dynamic modeling scheme based on a hybrid of multiple data-driven algorithms was proposed. First, processed abnormal values and normalized the data. To improve the relevance of the input data, used MIC to estimate delay time and reconstructed production data. Then used combined feature selection method to determine input variables. To further mine data information, VMD was used to decompose input time series. Finally, established NOx emission prediction model combining ELM and EC model. Experimental results based on actual historical operating data show that the MAPE of predicted results is 2.61%. Model sensitivity analysis shows that besides the amount of ammonia injection, the inlet oxygen concentration and the flue gas temperature have a significant impact on NOx emission, which should be considered in SCR process control and optimization.

description: TiO2/H2O2 mediated UV photocatalysis was studied for estimating the degradation of cypermethrin in a synthetic aqueous solution. All the experiments were performed in a laboratory scale photo-reactor under UV-A (~365 nm) irradiation. Optimisation of the process parameters was done to achieve maximum degradation of cypermethrin. The process parameters chosen for this investigation were concentration of TiO2 (0.5 to 2 g/L), concentration of H2O2 (50 to 350 mg/L) and initial pH of the reaction mixture (2 to 10). A three-level Box-behnken factorial design (BBD) in combination with Response Surface Methodology (RSM) was adopted to perform the optimisation process. Further, thermal treatment method was adopted to regenerate the TiO2 particles and their reusability was assessed. The findings of this analysis revealed that after 3 h of reaction time and at optimised conditions (i.e., concentration of TiO2 = 0.65 g/L; concentration of H2O2 = 179 mg/L and pH = 3.9), 48.30% of cypermethrin was degraded and subsequent biodegradability index, of the reaction mixture, improved from 0.55 to 0.3. Also, it was estimated that the adsorption and photocatalytic degradation processes followed Langmuir isotherm and first-order kinetics, respectively. The TiO2 particles were observed to be reusable as, after five cycles only 12.6% reduction was observed in its degradation efficiency. The findings of this study may prove beneficial for treating the pesticides’-contaminated water bodies, in the tropical countries, where sunlight is intense and pesticides are continuously entering into the water bodies from nearby agricultural fields.

description: We find sufficient conditions for the singularity of a substitution $\mathbb{Z}$-action's spectrum, which generalize the conditions given in arXiv:2003.11287, Theorem 2.4, and we also obtain a similar statement for a collection of substitution $\mathbb{R}$-actions, including the self-similar one. To achieve this, we first study the distribution of related toral endomorphism orbits. In particular, given a toral endomorphism and a vector $\mathbf{v}\in\mathbb{Q}^d$, we find necessary and sufficient conditions for the orbit of $ω\mathbf{v}$ to be uniformly distributed modulo $1$ for almost every $ω\in\mathbb{R}$. We use our results to find new examples of singular substitution $\mathbb{Z}$- and $\mathbb{R}$-actions.

description: Malathion is one of the most well-known pesticides which is widely used for controlling insects and pests. Slow degradation and extensive and/or inappropriate use of malathion have resulted in the contamination of the environment inflicting hazardous damages to the ecosystems and human health. This systematic study along with meta-analysis is aimed at reviewing a vast number of reports on the application of the above-mentioned methods used for the extraction and detection of malathion in a wide variety of samples. Initially, the relevant articles over the last decade (2011-2020) were selected for the meta-analysis and subsequently systematically reviewed. The major key points of each article were extracted by a predefined data template. In addition, the statistical analyses were performed by the R software. Following a thorough screening, 812 articles were found to be suitable. Of which, 68 were finally selected which met the required quantitative criteria for the meta-analysis. Meta-analysis was conducted by the random-effects model with a high heterogeneity (I2 = 99.99%). The pooled results on the selected articles revealed that the solid phase-based methods in combination with gas chromatography-mass spectroscopy (GC-MS) have gained lots of interest among the researchers. Within the mentioned articles, the respective recoveries, LODs and LOQs were reported to fall in the range of 95.43-139%, 0.000026-100 µg/l, 0.000078-300 µg/l and 97.20-136%, 0.00001-1.3 µg/g, 0.00005-4.2 µg/g for the aqueous and solid matrices. The results also revealed that the maximum recovery was affiliated to the SPE method (139%) for the aqueous matrices, while the corresponding value for the solid matrices was 134%. According to the pooled data, the mean recoveries varied in the ranges of 92.11-102.50 % and 92.21-102.91% in the aqueous and solid matrices, respectively. The maximum recovery of malathion was assigned to the extraction by SPE (101.46%, 95% CI= 94.66-108.27).

description: The residue behaviours of difenoconazole, bifenthrin, thiamethoxam and its metabolite clothianidin on representative crops such as cucumber, bitter gourd, loofah, zucchini, tomato, cherry tomato, eggplant, cowpea, kidney bean, celery, and fennel were investigated. The effects of factors such as fruit size, property of epidermis, leaf size and others on pesticide residues were studied, and then analysed whether these crops are suitable for the same group. Results indicated residue extrapolation could be made between the different crop groups or subgroups. It could be extrapolated from high-risk residue crops to the low-risk residue crops. Cherry tomato or eggplant could be extrapolated to tomato, and bitter gourd or loofah could be extrapolated to cucumber or zucchini, and the reverse was unacceptable. For these four vegetable groups, the different edible parts led to a significant difference in pesticide residues, celery and fennel had higher residue risk because the edible parts were whole plants including the leaves. The residue difference in the same edible parts of the different crop groups was not obvious, such as the Fruiting vegetables, Cucurbits group and the Fruiting vegetables, other than Cucurbit group. The processing factor (PF) extrapolation was more reasonable because crop varieties had no significant effect on pesticide residues in processed commodities. From the perspective of pesticide residues, representative crops were proposed and the rationality of crop classification and residue extrapolation was analysed. These results could promote the process of pesticide registration and the settlement of Maximum Residue Limit (MRL) standards, and further solve the missing of MRL for minor crops.

description: In this work, we test the capability of an exact solution found in the framework of a nonlinear extension of the Israel-Stewart theory to fit the supernovae Ia, gravitational lensing, and black hole shadow data. This exact solution is a generalization of one previously found for a dissipative unified dark matter model in the context of the near-equilibrium description of dissipative processes, where we do not have the full regime of the nonlinear picture. This generalized solution is restricted to the case where a positive entropy production is guaranteed and is tested under the condition that ensures its causality, local existence, and uniqueness. From the observational constraints, we found that this generalized solution is a good candidate in the description of the observational late-time data used in this work, with best-fit values $H_{0}=73.2_{-0.9}^{+0.8}\,\frac{km/s}{Mpc}$, $q_{0}=-0.41_{-0.03}^{+0.03}$, $\hatξ_{0}=0.88_{-0.17}^{+0.09}$, $ε=0.34_{-0.04}^{+0.03}$, and $k=0.27_{-0.20}^{+0.37}$. Therefore, we show that the nonlinear regime of the Israel-Stewart theory consistently describes the recent accelerated expansion of the universe without the inclusion of some kind of dark energy component and also provides a more realistic description of the fluids that make up the late Universe.

description: We characterize the energy transport in a one dimensional $\mathbb{Z}_3$ chiral clock model. The model generalizes the $\mathbb{Z}_2$ symmetric transverse field Ising model (TFIM). The model is parametrized by a chirality parameter $θ$, in addition to $f$ and $J$ which are analogous to the transverse field and the nearest neighbour spin coupling in the TFIM. Unlike the well studied TFIM and XYZ models, does not transform to a fermionic system. We use a matrix product states implementation of the Lindblad master equation to obtain the non-equilibrium steady state (NESS) in systems of sizes up to $48$. We present the estimated NESS current and its scaling exponent $γ$ as a function of $θ$ at different $f/J$. The estimated $γ(f/J,θ)$ point to a ballistic energy transport along a line of integrable points $f=J\cos{3θ}$ in the parameter space; all other points deviate from ballistic transport. Analysis of finite size effects within the available system sizes suggest a diffusive behavior away from the integrable points.

description: A systematic review and meta-analysis of randomized controlled trials (RCTs) were performed to examine treatment-related adverse events (TRAEs) for combination of nivolumab (NIVO) and ipilimumab (IPI) compared to NIVO monotherapy among cancer patients. We searched several databases to identify relevant RCTs. Meta-analysis was performed using random-effects model. In fourteen RCTs included in the study, we found that compared to NIVO monotherapy, combination NIVO + IPI increased the risk of any grade (Risk Ratio (RR) = 1.11), and grade 3 or 4 (RR = 1.95) TRAEs. Compared to NIVO, NIVO + IPI had higher risk for any grade colitis (RR = 4.52), pneumonitis (RR = 3.06), and diarrhea (RR = 1.68).

description: Il saggio intende circoscrivere i contorni di un processo, quello della delegittimazione – sino ad ora assente nell’indagine storiografica – strettamente connesso con l’analisi dei fondamenti del potere politico. Partendo dalla classica analisi weberiana sulla legittimazione del potere, il saggio distingue la delegittimazione dal normale confronto politico e dal dissenso considerandola come un fenomeno di contestazione del potere che si realizza all’interno di un sistema di valori comuni o almeno in parte condivisi dagli attori politici. Ne può così derivare un atteggiamento di contestazione radicale della legittimità di un potere o di un’aspirazione al potere che potrebbe sfociare in aperto conflitto. Sulla base di questa definizione il saggio prende in esame alcuni esempi storici di delegittimazione cercando di mostrarne il differente andamento nei regimi democratici, nelle crisi transizioni di regime e nelle dittature.

description: The real-time prediction of NOx emissions is of great significance for pollutant emission control and unit operation of coal-fired power plants. Aiming at dealing with the large time delay and strong nonlinear characteristics of the combustion process, a dynamic correction prediction model considering the time delay is proposed. First, the maximum information coefficient (MIC) is used to calculate the delay time between related parameters and NOx emissions, and the modeling data set is reconstructed; then, an adaptive feature selection algorithm based on Lasso and ReliefF is constructed to filter out the high correlation with NOx emissions. Parameters; Finally, an extreme learning machine (ELM) model combined with error correction was established to achieve the purpose of dynamically predicting the concentration of nitrogen oxides. Experimental results based on actual data show that the same variable has different delay times under load conditions such as rising, falling, and steady; and there are differences in model characteristic variables under different load conditions; dynamic error correction strategies effectively improve modeling accuracy; proposed The prediction error of the algorithm under different working conditions is less than 2%, which can accurately predict the NOx concentration at the combustion outlet, and provide guidance for NOx emission monitoring and combustion process optimization.

description: Seroconversion rates were compared between oncological and nononcological patients infected with SARS-CoV-2 during a 14-day hospitalization time. All COVID-19 non-oncological and solid malignancies patients reached 100% seroconversion at day 14, while less than half of the hematological patients were seroconverted at the same time point. Despite the limited number and variability of the patient’s cohort, we conclude that there is a delayed seroconversion in the hematological malignancies group, which may be linked to changes in the hematological parameters, immune suppression and/or oncological treatments that are typically associated with these patients.

description: The removal of pollutants such as dyes and bacteria has become a tedious process hence there is a need for multifunctional materials that can be used for the removal or degradation of various pollutants from wastewater. In this study, a flowerlike NiO nanoparticle was synthesised and used for the removal of dyes and bacterial from water. Sutherlendia frutescene plant extract was used as a reducing agent. SEM and XRD confirmed the formation of this material through morphological analysis and phase identification, respectively. EDX further corroborated the formation with the present dominant phases of Ni and O. TGA showed the material was stable, furthermore, UV-Vis was able to demonstrate the optical properties of the material with excitation at the absorption wavelength of 302 nm and with a bandgap of 3.5 eV. This material was further tested for the degradation of two dye pollutants, methylene blue and malachite green. A percentage degradation of 89% and 98%, respectively, was achieved. The materials could be reused at least three times before losing their stability. Upon testing the model bacterial strains, E. faecalis and P. aurugenosa,the SfNiO activity was more active towards gram-positive bacteria. This study has shown that it is possible to produce environmentally safe materials that can be used for the degradation of various dyes and removal of both gram-negative and gram-positive bacterial strains in our water streams.
