description: In this paper, our purpose is to construct Genocchi wavelet functions (GWFs) and applied them for the numerical solution of various types of conformable fractional differential equations. Also, we present the operational matrices of GWFs, to reduce conformable fractional differential equations to a system of algebraic equations. In addition, we examine several examples to illustrate accuracy and efficiency of the proposed method.

description: We present methods for calculating a measure of phonotactic complexity---bits per phoneme---that permits a straightforward cross-linguistic comparison. When given a word, represented as a sequence of phonemic segments such as symbols in the international phonetic alphabet, and a statistical model trained on a sample of word types from the language, we can approximately measure bits per phoneme using the negative log-probability of that word under the model. This simple measure allows us to compare the entropy across languages, giving insight into how complex a language's phonotactics are. Using a collection of 1016 basic concept words across 106 languages, we demonstrate a very strong negative correlation of -0.74 between bits per phoneme and the average length of words.

description: Smartwatch comfort is a fundamental factor that significantly influences the user experience and provides crucial guidance for the evolution of wearable technology. However, there is currently a lack of a comprehensive theoretical model to describe the dimensions of smartwatch comfort and their corresponding influencing factors. Therefore, the present study employed a bottom-up grounded theory approach to construct a user-centered model for smartwatch comfort. Through the coding of in-depth interviews with 64 smartwatch users, we discovered that smartwatch comfort encompasses both physiological dimensions (e.g., pressure and foreign body sensation) and psychological dimensions (e.g., perceived intelligence and satisfaction of needs). Furthermore, the features of smartwatches, including physical attributes (e.g., size and material) and functionalities (e.g., interoperability and automation capabilities), directly impact the comfort experience. Additionally, individual and contextual factors can explain variations in the comfort experience of smartwatches. Users with different physiological characteristics (e.g., wrist size and body sensitivity) and psychological needs (e.g., utilitarian or hedonic needs) are influenced differently by the factors of smartwatches that affect their comfort experience. The adaptability of smartwatches across different contexts (including task context, social context, and temporal context) is also a significant influencing factor on comfort. This substantive grounded theory provides crucial guidance for the selection of core variables in future quantitative research and contributes to the development of smarter, more comfortable, and user-centric smartwatches.

description: The synthesis of catechol polymers often demands tedious protection and deprotection steps. In this work, the role of a guanidine base to subdue the catechol functions and promote the ring-opening polymerization (ROP) is suggested. Accordingly, guanidine, 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (MTBD), was employed to mediate ROP of N-carboxyanhydride (NCA) from a catechol initiator. MTBD played a dual-role in ROP of sarcosine-NCA (Sar-NCA) and masking the catechol initiator concurrently. Catechol-ended polysarcosine (PSar) was synthesized with a predicted molecular weight (Mn,SEC = 3.5 kg mol−1, Mn,NMR = 3.7 kg mol−1) and narrow dispersities (Đ

Signal reconstruction is performed using a version of Sobolev duals for fusion frames, and numerical experiments are given to validate the overall performance.

description: Soybean (Glycine hispida Moench.) is a promising legume crop that can solve problems of plant protein and fat, improve soil nitrogen balance and increase food production. It removes significant quantities of nutrients from the soil, so it has the potential to improve the soil's nutrient balance. There is no doubt about the importance of soybeans as a crop that can solve the problem of vegetable protein and fat, improve the nitrogen balance of soils and increase food production. With an increase in the area of soybean crops, we note a rather low level of crop yields, when the realization of the genetic productivity potential of its modern varieties under production conditions is 50% or less. The reason for this is primarily the violation by farmers of the technological process of crop production and the lack of clear scientifically sound recommendations for cultivation technology. It is therefore an important issue that the increase in productivity of this crop is being studied. The results of the research on the influence of foliar feeding by multicomponent chelate micro fertilizers on the yield and quality of the soybean grain are given in the article. The passage of growth processes, namely height, density and the factors influencing their passage have been investigated. The maximum survival rates of soybean plants were observed in the variant with double application of the micro fertilizer Vuksal Microplant in the phases of budding and green beans. At the same time the number of plants in Merlin during harvesting was 56.2 units / M2, and the survival rate was 93.2%, while in Kent variety, respectively, 45.7 units / M2 and 91.3%. The studies revealed that the average daily growth of soybean plants of Merlin variety was in the range of 0.90-0.94 cm, while that of Kent variety was 0.96-1.00 cm.

description: We show how the MHV diagram description of Yang-Mills theories can be used to study non-supersymmetric loop amplitudes. In particular, we derive a compact expression for the cut-constructible part of the general one-loop MHV multi-gluon scattering amplitude in pure Yang-Mills theory. We show that in special cases this expression reduces to known amplitudes - the amplitude with adjacent negative-helicity gluons, and the five gluon non-adjacent amplitude. Finally, we briefly discuss the twistor space interpretation of our result.

The interface between the arrays supports two distinct topological edge states, which can be resonantly coupled by additional weak longitudinal refractive index modulation with a period larger than the helix period. In the presence of Kerr nonlinearity, such coupled edge states enable topological Bragg solitons. Theory and examples of such solitons are presented.

description: We calculate the dressed gluon and ghost propagators of Landau gauge Yang-Mills theory in the complex momentum plane from their Dyson-Schwinger equations. To this end, we develop techniques for a direct calculation such that no mathematically ill-posed inverse problem needs to be solved. We provide a detailed account of the employed ray technique and discuss a range of tools to monitor the stability of the numerical calculation. Within a truncation employing model ansaetze for the three-point vertices and neglecting effects due to four-point functions, we find a singularity in the gluon propagator in the second quadrant of the complex $p^2$-plane. Although the location of this singularity turns out to be strongly dependent on the model for the three-gluon vertex, it occurs always at complex momenta for the range of models considered.

description: The intrinsic difficulties in building realistic climate models and in providing complete, reliable and meaningful observational datasets, and the conceptual impossibility of testing theories against data imply that the usual Galilean scientific validation criteria do not apply to climate science. The different epistemology pertaining to climate science implies that its answers cannot be singular and deterministic; they must be plural and stated in probabilistic terms. Therefore, in order to extract meaningful estimates of future climate change from a model, it is necessary to explore the model' uncertainties. In terms of societal impacts of scientific knowledge, it is necessary to accept that any political choice in a matter involving complex systems is made under unavoidable conditions of uncertainty. Nevertheless, detailed probabilistic results in science can provide a baseline for a sensible process of decision making.

description: The objective of this study was to better understand the process of adopting occupational exoskeletons and the phases of acceptability and acceptance in particular. The studies focused mainly on acceptance. This topic given considerable attention, particularly in the framework of information systems, whereas it received less attention in the case of occupational exoskeletons. A questionnaire for studying both acceptability and acceptance based on the UTAUT and the concepts of Situated Acceptance was designed. This questionnaire was organized around seven dimensions comprising a total of 33 items. Two data collection campaigns were performed. They were composed of two samples of respondents with different characteristics. To explore correlations within these seven dimensions and the acceptability and/or acceptance of exoskeletons, PLS path modeling, i.e., causal modeling, was used. The results show that the same dimensions are involved in the acceptability and acceptance processes. However, the dimensions are organized differently and have different impacts according to it is acceptability or acceptance. The models were identified, their formalization as dimensions and their operationalization in questionnaire form were validated. This questionnaire is a subjective tool for assessing exoskeletons that permits identifying elements that impede or facilitate acceptance. It permits monitoring the dynamics of the different dimensions involved in acceptance during the utilization of exoskeletons by operators. Lastly, from a more qualitative standpoint, it could also be used as an interview guide for exchanges with future users or users.
The indoor environmental quality (IEQ) survey of Canadian households : a focus on indoor air quality, lighting, and acoustics
Creators: name: Spetic, Wellington C.
Publisher: name: University of British Columbia
Year: 2009

description: This study examined aspects of the Healthful Living concept in the Canadian housing market. This is a marketing research project which focused on what Canadian householders value and desire in the indoor environment of their homes, particularly the indoor air quality, lighting, and acoustics. A nationwide sample consisting of 3,592 Canadian households was investigated revolving around issues of consumer demand for healthier homes. The major topics assessed were: 1) identification of consumer groups that show an interest in certain aspects of the indoor environment through demographic and psychographic segmentation; 2) measurement of the levels of importance and knowledge of some issues related to indoor environmental quality; and 3) willingness to pay for better indoor environmental quality. Results showed that 56% percent of the respondents are knowledgeable or have heard the term "Healthy House" before. Modeling using a logistic regression algorithm was conducted to determine whether the likelihood of paying more for better indoor environmental quality features could be predicted. Cluster analysis was used to identify consumer groups that valued or were more knowledgeable about some aspects of the indoor environmental quality. Products and materials promoting energy efficiency, natural light, better insulation, and non-allergic qualities were preferred in a choice/preference question of nine attributes regarding Healthier Homes. There seems to be a market and opportunities for the Healthful Living concept to establish itself in the Canadian housing sector which may offer great prospects to the Canadian wood industry and its segments.

description: Wigner functions play a central role in the phase space formulation of quantum mechanics. Although closely related to classical Liouville densities, Wigner functions are not positive definite and may take negative values on subregions of phase space. We investigate the accumulation of these negative values by studying bounds on the integral of an arbitrary Wigner function over noncompact subregions of the phase plane with hyperbolic boundaries. We show using symmetry techniques that this problem reduces to computing the bounds on the spectrum associated with an exactly-solvable eigenvalue problem and that the bounds differ from those on classical Liouville distributions. In particular, we show that the total ``quasiprobability'' on such a region can be greater than 1 or less than zero.

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: We study double-winding Wilson loops in $SU(N)$ lattice Yang-Mills gauge theory by using both strong coupling expansions and numerical simulations. First, we examine how the area law falloff of a ``coplanar'' double-winding Wilson loop average depends on the number of color $N$. Indeed, we find that a coplanar double-winding Wilson loop average obeys a novel ``max-of-areas law'' for $N=3$ and the sum-of-areas law for $N\geq 4$, although we reconfirm the difference-of-areas law for $N=2$. Second, we examine a ``shifted'' double-winding Wilson loop, where the two constituent loops are displaced from one another in a transverse direction. We evaluate its average by changing the distance of a transverse direction and we find that the long distance behavior does not depend on the number of color $N$, while the short distance behavior depends strongly on $N$.

description: Depression is a common mental disturbance that can be categorized as mild, moderate or severe. Mesemberine alkaloids, the main recognized phytoconstituents of some plants belonging to family Mesembryanthemaceae, are well-known as serotonin reuptake inhibitors. Therefore, the objective of this study is to evaluate the antidepressant activity of the alkaloidal fraction of Mesembryanthemum cordifolium L.f. (Aptenia cordifolia) roots, family Mesembryanthemaceae using forced swimming test, assisted by metabolomic analysis and in silico ligand-based and structure-based screening. Results showed that the alkaloidal fraction displayed an antidepressant activity superior to imipramine hydrochloride, a standard antidepressant agent. Nine alkaloids were annotated from the metabolomic analysis. Interestingly, among the dereplicated constituents, mesembrane (5) displayed strong binding affinity to SERT protein, which is slightly higher than the antidepressant drug venlafaxine. In conclusion, the alkaloidal fraction of the M. cordifolium (A. cordifolia) root exhibits an antidepressant activity which can be attributed in part to mesembrane (5).

description: The electrical conductivity of a pion gas at low temperatures is studied in the framework of Linear Response and Chiral Perturbation Theory. The standard ChPT power counting has to be modified to include pion propagator lines with a nonzero thermal width in order to properly account for collision effects typical of Kinetic Theory. With this modification, we discuss the relevant chiral power counting to be used in the calculation of transport coefficients. The leading order contribution is found and we show that the dominant higher order ladder diagrams can be treated as perturbative corrections at low temperatures. We find that the DC conductivity $σ(T)$ is a decreasing function of $T$, behaving for very low $T$ as $σ(T)\sim e^2m_π\sqrt{m_π/T}$, consistently with nonrelativistic Kinetic Theory. When unitarization effects are included, $σ(T)$ increases slowly as $T$ approaches the chiral phase transition. We compare with related works and discuss some physical consequences, especially in the context of the low-energy hadronic photon spectrum in Relativistic Heavy Ion Collisions.

description: Maize varieties and hybrids are characterized by increased requirements for nutritional conditions and only with a full and balanced supply of nutrients can fully realize their genetic potential. An important measure of modern intensive technologies for growing high yields of corn for grain is the use of biologically active compounds that can affect the intensity of physiological processes and affect the production process of agricultural production. In addition to growth stimulants, much attention is paid to the use of trace elements that are active catalysts that accelerate biochemical reactions and affect their direction. Lack of micronutrients can adversely affect the growth and development of corn plants. Treatment of corn seeds before sowing with growth stimulant Biolan, normal consumption of 15 ml/t, and during the growing season of corn plants in the phase of 6-7 leaves of foliar spraying with micronutrients Quantum Gold at a rate of 2 l/ha + Chelatin Zinc, 1 l/ha, will allow to obtain grain yield of maize hybrids at the level of 6,79-8,17 t/ha.

description: U.S. beef producers have always been concerned that beef imports may depress prices. Consumer groups have held the opposite view. This research addresses this issue by assessing the impact of beef imports on wholesale domestic beef prices. This is done by estimating the flexibilities between domestic beef, choice and select grades, and imported beef at the wholesale level. No statistical evidence is found to support either producer or consumer view. This may be resultant of small import volumes of beef. Beef exports, however, have a statistically measurable effect on domestic beef prices, especially the select grade.

description: Mixing above the proto-neutron star is believed to play an important role in the supernova engine, and this mixing results in a supernova explosion with asymmetries. Elements produced in the innermost ejecta, e.g., ${}^{56}$Ni and ${}^{44}$Ti, provide a clean probe of this engine. The production of ${}^{44}$Ti is particularly sensitive to the exact production pathway and, by understanding the available pathways, we can use ${}^{44}$Ti to probe the supernova engine. Using thermodynamic trajectories from a three-dimensional supernova explosion model, we review the production of these elements and the structures expected to form under the "convective-engine" paradigm behind supernovae. We compare our results to recent X-ray and $γ$-ray observations of the Cassiopeia A supernova remnant.

description: The dynamic structure factor of lithium-diborate glass has been measured at several values of the momentum transfer $Q$ using high resolution inelastic x-ray scattering. Much attention has been devoted to the low $Q$-range, below the observed Ioffe-Regel crossover \qco{}$\simeq$ 2.1 nm$^{-1}$. We find that below \qco{}, the linewidth of longitudinal acoustic waves increases with a high power of either $Q$, or of the frequency $Ω$, up to the crossover frequency \OMco{} $\simeq$ 9 meV that nearly coincides with the center of the boson peak. This new finding strongly supports the view that resonance and hybridization of acoustic waves with a distribution of rather local low frequency modes forming the boson peak is responsible for the end of acoustic branches in strong glasses. Further, we present high resolution Brillouin light-scattering data obtained at much lower frequencies on the same sample. These clearly rule out a simple $Ω^2$-dependence of the acoustic damping over the entire frequency range.

description: In this paper we derive and discuss the completely spin- and photon-polarisation dependent probability rates for nonlinear Compton scattering and nonlinear Breit-Wheeler pair production. The locally constant field approximation, which is essential for applications in plasma-QED simulation codes, is rigorously derived from the strong-field QED matrix elements in the Furry picture for a general plane-wave background field. We discuss important polarisation correlation effects in the spectra of both processes. Asymptotic limits for both small and large values of $χ$ are derived and their spin/polarisation dependence is discussed.

description: In the paper, preliminary results of the analysis of potential use of climate forecast information in designing rainfall index insurance in the southeastern region of the U.S. are reported. Joint distributions of bi-monthly rainfall and El Nino Southern Oscillation (ENSO) indexes are estimated using copula analysis of historical data. The risk reducing effectiveness of introducing premiums conditional on ENSO forecast is evaluated. The results indicate some dependence of the downward volatility of rainfall on the lagged ENSO (forecast) index, particularly in the coastal areas and in the late winter and spring.
On (the Lack of) Code Confidentiality in Trusted Execution Environments

description: Trusted Execution Environments (TEEs) have been proposed as a solution to protect code confidentiality in scenarios where computation is outsourced to an untrusted operator. We study the resilience of such solutions to side-channel attacks in two commonly deployed scenarios: when a confidential code is a native binary that is shipped and executed within a TEE and when the confidential code is an intermediate representation (IR) executed on top of a runtime within a TEE. We show that executing IR code such as WASM bytecode on a runtime executing in a TEE leaks most IR instructions with high accuracy and therefore reveals the confidential code. Contrary to IR execution, native execution is much less susceptible to leakage and largely resists even the most powerful side-channel attacks. We evaluate native execution leakage in Intel SGX and AMD SEV and experimentally demonstrate end-to-end instruction extraction on Intel SGX, with WASM bytecode as IR executed within WAMR, a hybrid between a JIT compiler and interpreter developed by Intel. Our experiments show that IR code leakage from such systems is practical and therefore question the security claims of several commercial solutions which rely on TEEs+WASM for code confidentiality.

description: Speech synthesis (text to speech, TTS) and recognition (automatic speech recognition, ASR) are important speech tasks, and require a large amount of text and speech pairs for model training. However, there are more than 6,000 languages in the world and most languages are lack of speech training data, which poses significant challenges when building TTS and ASR systems for extremely low-resource languages. In this paper, we develop LRSpeech, a TTS and ASR system under the extremely low-resource setting, which can support rare languages with low data cost. LRSpeech consists of three key techniques: 1) pre-training on rich-resource languages and fine-tuning on low-resource languages; 2) dual transformation between TTS and ASR to iteratively boost the accuracy of each other; 3) knowledge distillation to customize the TTS model on a high-quality target-speaker voice and improve the ASR model on multiple voices. We conduct experiments on an experimental language (English) and a truly low-resource language (Lithuanian) to verify the effectiveness of LRSpeech. Experimental results show that LRSpeech 1) achieves high quality for TTS in terms of both intelligibility (more than 98% intelligibility rate) and naturalness (above 3.5 mean opinion score (MOS)) of the synthesized speech, which satisfy the requirements for industrial deployment, 2) achieves promising recognition accuracy for ASR, and 3) last but not least, uses extremely low-resource training data. We also conduct comprehensive analyses on LRSpeech with different amounts of data resources, and provide valuable insights and guidances for industrial deployment. We are currently deploying LRSpeech into a commercialized cloud speech service to support TTS on more rare languages.

description: The effects of monovalent (Na+, K+) and divalent (Mg2+, Ca2+, Mn2+) ions on the interaction between DNA and histone are studied using the molecular combing technique. Lamda-DNA molecules and DNA-histone complexes incubated with metal cations (Na+, K+, Mg2+, Ca2+, Mn2+) are stretched on hydrophobic surfaces, and directly observed by fluorescence microscopy. The results indicate that when these cations are added into the DNA solution, the fluorescence intensities of the stained DNA are reduced differently. The monovalent cations (Na+, K+) inhibit binding of histone to DNA. The divalent cations (Mg2+, Ca2+, Mn2+) enhance significantly the binding of histone to DNA and the binding of the DNA-histone complex to the hydrophobic surface. Mn2+ also induces condensation and aggregation of the DNA-histone complex.

description: Florida’s open-space land-acquisition program is one of the most aggressive in the country, with $3.7 billion paid for 3.8 million acres since 1972. Using data from the Conservation and Recreational Lands (CARL) program, hedonic analyses found that acquiring private lands with valuable natural resources, habitat for rare species, and important historical sites for public preservation is more costly. Development potential and pressure also increased acquisition costs. The presence of additional endangered natural elements and needing to contract with additional landowners, however, were found to decrease the cost. Results provide a basis for landowners and land-acquisition agencies to negotiate.

description: A HP20 resin-based unique method was adopted to get an active fraction of the hydroalcoholic extract of G. glabra roots. The fraction showed potent cytotoxicity against cancer cell line and was further subjected to detailed phytochemical investigation to obtain ten biomarkers. The isolated compounds were also tested for the cytotoxicity against the C6 glioma cell line in vitro using MTT assay. Among the isolated compounds, glycyrrhetic acid (1), glabrol (6), and glabridin (9) exhibited significant cytotoxicity. The compounds showed a dose-dependent decrease in cell viability. The active compounds were subjected to molecular docking study against topoisomerase I and topoisomerase II to support the mechanism of antitumor activity.
