Fast OMP algorithm and its FPGA implementation for compressed sensing-based sparse signal acquisition systems

Compressed sensing ‐ based radio frequency signal acquisition systems call for higher reconstruction speed and low dynamic power. In this study, a novel low power fast orthogonal matching pursuit (LPF ‐ OMP) algorithm is proposed for faster reconstruction of sparse signals from their compressively sensed samples and the reconstruction circuit consumes very low dynamic power. The searching time to find the best column is reduced by reducing the number of columns to be searched in successive iterations. A novel architecture of the proposed LPF ‐ OMP algorithm is also presented here. The proposed architecture is implemented on field programmable gate array for demonstrating the performance enhancement. Computation of pseudoinverse in OMP is avoided to save time and storage requirement to store the pseudoinverse matrix. The proposed design incorporates a novel strategy to stop the algorithm without consuming any extra circuitry. A case study is carried out to reconstruct the RADAR test pulses. The design is implemented for K = 256, N = 1024 using XILINX Virtex6 device and supports maximum of K /4 iterations. The proposed design is faster, hardware efficient and consumes very less dynamic power than the previous implementations of OMP. In addition, the proposed implementation proves to be efficient in reconstructing low sparse signals.
Anomalies in the China A-share Market

This paper sheds light on the similarities and differences with respect to the presence of anomalies in the China A-share market and other markets. To this end, we examine the existence of 32 anomalies in the China A-share market over the period 2000-2019. We find that value, risk, and trading anomalies carry over to China A-shares. Evidence for anomalies in the size, quality, and past return categories is substantially weaker, with the exception of a strong residual momentum and reversal effect. We document that most anomalies cannot be explained by industry composition, and are present among large, mid, and small capitalization stocks. We are the first to examine the existence of residual reversal, return seasonalities, and connected firm momentum for the China A-share market. We find strong out-of-sample evidence for the former two, but not the latter. Specific characteristics of the China A-share market, such as short-sale restrictions, the prevalence of state-owned enterprises, and the effect of stock market reforms, are examined in more detail. These features do not seem to be important drivers of our empirical findings.
Direct energy landscape sampling of the homogeneous nucleation and crystal growth of a model liquid

A material’s properties can be effected greatly by the method of synthesis of the material. The first step in the synthesis of any material is the nucleation of the material’s phase. Nucleation and crystal growth are understood to be activated processes involving the crossing of free-energy barriers. Attempts to capture the entire crystallization process over long timescales with molecular dynamic simulations have met major obstacles because of the temporal constraints of molecular dynamics. Herein, we circumvent this temporal limitation by using an improved metadynamics method based on the adaptive basin-climbing algorithm to directly sample the potential-energy landscape of a monotonic, model-liquid Argon system. The algorithm biases the system to evolve from a liquid-like structure towards an FCC crystal structure through inherent structures. Compared to other computational techniques, our method requires no assumptions about the shape, size, or thermodynamics properties of the critical crystal nucleus, and does not require a nucleation seed to simulate the growth process. Consequently, the sampled timescale is macroscopically long, magnitudes longer than molecular dynamics simulations. Thus, we observe that the formation of a crystal involves two processes, each with a unique temperature-dependent energy barrier. One barrier corresponds to the creation of a crystal nucleation site; the other barrier corresponds to the crystal growth. We find the two processes dominate in different temperature regimes. Further, we provide empirical evidence for the nonmonotonic temperature dependence of the nucleation energy barrier and the nucleation rate. Then, we also use metadynamics on a fragile glass forming system, and compare the landscape and timescale of the fragile glass former to the good crystal former. The stark difference in landscapes provides an energy landscape explanation for the nucleation process. The success of this method on a model liquid system is encouraging for elucidating the crystallization of more complex systems.
Effect of ozonation on the Staphylococcus Aureus innoculated in milk

The aim of this research was evaluate the efficiency of the action of ozonation of milk on the reduction of the bacterial counts of Staphylococcus aureus artificially inoculated and subjected to different binomials times/concentrations of ozone. The samples were divided in four assays: 1 and 2, with skim milk and ozone concentrations of 34.7 mg L –1 and 44.8 mg L-1, respectively, and assays 3 and 4, with whole milk and the same concentrations of ozone. The time of ozonation in all of the assays was 5 (T1), 10 (T2), 15 (T3), 20 (T4) and 25 (T5) minutes. Each treatment was replicated three times. The bacterial counts were determined immediately before and after the ozonation process by plating the samples on Baird Parker agar. In treatments 1 and 2, the greatest reductions were 0.42 log10 CFU/mL (colony forming units per millilitre), whereas in treatments 3 and 4, the greatest reductions were 0.19 and 0.21 log10 CFU/mL, respectively. The results of all of the tests show that, for T1, there was no reduction in the microbial load, whereas for T2, there was a sharp decrease in the microbiota, and this decrease was even more significant for T4 and T5. In both skim and whole milk with ozone concentrations of 34.7 and 44.8 mg L-1, the reductions were significantly greater after 20 minutes of ozonation. The results indicated that ozone showed low efficacy in the reduction of S.aureus inoculated into fluid milk and milk fat interferes with the bactericidal action of the gas.
Effects of pigment richness and size variation on coexistence, richness and function in light‐limited phytoplankton

Trait diversity is traditionally seen as promoting species richness and ecosystem function. Species with dissimilar traits would partition available resources, increasing niche differences, facilitating coexistence and increasing ecosystem function. Here we first show, using theory and simulations for light‐limited phytoplankton, that combing photosynthetic pigments is indeed a necessary condition for coexistence and stimulates ecosystem function. However, pigment richness does mostly not permit the coexistence of more than two species, and increases productivity at most 40% compared to single‐pigment communities. That is because blending in more pigments leads to coexistence of species with many pigments and therefore flat absorption spectra, which equalizes their fitness but decreases their niche differences. Similarly, seeding species with more variable size leads to an excess of large‐celled species, which does not only decrease fitness differences but also niche differences. Empirical data and additional simulations suggest that pigment richness effects can be stronger during transient dynamics but inevitably weaken with time, that is, pigment richness effects on species richness and function are likely short‐lived. Synthesis. Our results highlight the need to apply coexistence theory to understand the long‐term effects of trait diversity on biodiversity and ecosystem function.
Signifying nothing: the hyperreal politics of ‘apolitical’ games

ABSTRACT Developers of AAA videogames which feature recognizable military forces, governmental law enforcement agencies, and geopolitical conflicts routinely make claims that their works do not make “political statements. ” This article takes seriously the claims made by several developers, revealing their attempts to radically narrow the definition of the term “political. ” Through a critical discourse analysis, this article will articulate several key theses held forth by the developers regarding systemic media and expressivity, the responsibility of the player, and the inevitable constraints of production and technology. These points are deployed by the developers to build an argument for a reduced scope of the term “political,” as well as to propose an ideological framing of videogames as an expressive medium, which ultimately serve to obscure the role that ideology plays in the production of videogames.
The Fano effect in the point contact spectroscopy of heavy electron materials

We show that Fano interference explains how point contact spectroscopy in heavy-electron materials probes the emergence of the Kondo heavy-electron liquid below the same characteristic temperature ${T}^{\ensuremath{\ast}}$ as that seen in many other experiments and why the resulting measured conductance asymmetry reflects the universal Kondo liquid behavior seen in these. Its physical origin is the opening of a new channel for electron tunneling beyond that available from the background conduction electrons. We derive the Fano formula with a mean-field slave boson approach for the Kondo lattice model and generalize it to finite temperature and realistic situation by introducing empirical parameters. The resulting simple expression for the Fano interference provides a good fit to the experimental results for ${\text{CeCoIn}}_{5}$, ${\text{CeRhIn}}_{5}$, and ${\text{YbAl}}_{3}$, over the entire range of bias voltages, and deduce a lifetime of the heavy quasiparticle excitations that agrees well with recent state-of-the-art numerical calculations.
Contrasting the Emotions identified in Spanish TV debates and in Human-Machine Interactions

This work is aimed to contrast the similarities and differences for the emotions identiﬁed in two very different scenarios: human-to-human interaction on Spanish TV debates and human-machine interaction with a virtual agent in Spanish. To this end we developed a crowd annotation procedure to label the speech signal in terms of both, emotional categories and Valence-Arousal-Dominance models. The analysis of these data showed interesting ﬁndings that allowed to proﬁle both the speakers and the task. Then, Convolutional Neural Networks were used for the automatic classiﬁcation of the emotional samples in both tasks. Experimental results drew up a different human behavior in both tasks and outlined different speaker pro-ﬁles.
Tenure Expectations and Career Aspirations Among Female Assistant Professors in STEM

This study used social cognitive career theory to predict the career aspirations and tenure expectations of untenured female science, technology, engineering, and math (STEM) assistant professors. We hypothesized that contextual variables (perceived career barriers and institutional support for work–life balance) would directly predict career aspirations and tenure expectations. We also expected that these contextual variables would be indirectly related to career aspirations and tenure expectations through our self-efficacy variables (faculty task-specific self-efficacy and impostor beliefs). Data were collected from 214 untenured female faculty in STEM departments. Path analyses indicated that the hypothesized model was a good fit for the data. Institutional support for work–life balance produced direct and indirect pathways to career aspirations through faculty task-specific self-efficacy and an indirect pathway to tenure expectations through impostor beliefs, whereas perceived career barriers produced a direct pathway to career aspirations. Implications for research and practice are discussed.
Segregated and yet inclusive? the application process for upper secondary school in Iceland for students labelled as disabled through the lens of social justice

ABSTRACT Inclusive education is affirmed in Icelandic laws and regulations although, at upper secondary school level, schools can apply to establish special programmes for students who have been labelled as disabled. The application process for these programs differs from the one in the mainstream regarding arrangement and time. In this article, special attention will be paid to the application process for Icelandic students with intellectual disabilities at upper secondary level. We use Alecia Jackson’s and Lisa Mazzei’s methodology of thinking with theory by ‘plugging’ Iris Marion Young’s philosophical concepts of oppression regarding social justice into the text, and vice versa. This approach reveals a discriminatory application process where cultural imperialism has the upper hand causing a denial of group differences. Students are being marginalised based on their support needs which can, among other things, result in systemic violence.
A multi-proxy reconstruction of climate during the late-Pleistocene to early Holocene transition in the northeastern, USA

Abstract A multiproxy record from Twin Ponds, VT, is used to reconstruct climatic variability during the late Pleistocene to early Holocene transition. Pollen, ostracodes, δ18O, and lithologic records from 13.5 to 9.0 cal ka BP are presented. Pollen- and ostracode-inferred climatic reconstructions are based on individual species’ environmental preferences and the modern analog technique. Principal components analysis of all proxies highlights the overall warming trend and centennial-scale climatic variability. During the Younger Dryas cooling event (YD), multiple proxies show evidence for cold winter conditions and increasing seasonality after 12.5 cal ka BP. The early Holocene shows an initial phase of rapid warming with a brief cold interval at 11.5 cal ka BP, followed by a more gradual warming; a cool, wet period from 11.2 to 10.8 cal ka BP; and cool, dry conditions from 10.8 to 10.2 cal ka BP. The record ends with steady warming and increasing moisture. Post-YD climatic variability has been observed at other sites in the northeastern United States and points to continued instability in the North Atlantic during the final phases of deglaciation.
Helping Students Reflect on Their Interpersonal Skills: The Team Performance Scale (TPS)

Many instructors of program evaluation incorporate team-based service projects into their courses. What is often overlooked is that it provides a golden opportunity for students to reflect on the interpersonal skills necessary for teamwork. This paper explains how two instructors leveraged service project working groups to include reflection on interpersonal skills. Minor changes were made to the Team Performance Scale (TPS), a tool used for Team-Based Learning in medical education. We found it to be a practical and effective way to engage students in reflecting on behaviours associated with a high functioning team. This article will be of interest to instructors using team learning approaches to teach key competencies in program evaluation.
A study to assess the utility of poison severity score, pseudocholinesterase levels and Glasgow coma scale in predicting severity and clinical outcome of organophosphorus poisoning

Background: Suicides due to organophosphate self-poisoning is a major cause of concern world over. Organophosphate compounds (OP) possess a major cause of suicide in India. There is a greater need for tools to predict severity of OP poisoning. We in this study try to assess the utility of the Glasgow coma scale (GCS), pseudocholinesterase levels and the poisoning severity score (PSS) in estimating severity and clinical prognosis of OP poisoning in patients of south India. Methods: A prospective study was conducted over 2 years in department of medicine, KIMS hospital and research centre, patients who were >18 years of age were included. OP poisoning was determined by either history of consumption or clinical features. Pseudocholinesterase levels at admission, PPS and GCS scores were assessed at admission and at 24 hours. Clinical, demographical, and certain laboratory investigation were recorded. Patients were followed till the patient stayed in intensive care unit. Results: In present study 100 patients were enrolled. Significant association was observed between GCS (p<0.001), PSS (p<0.001) and outcome of OP poisoning. Unexpectedly no significant association was observed with pseudocholinesterase level (p=0.118). A total of 83% patients were improved after treatment and mortality rate observed was 17%. Out of these 83% severe complications were observed in 14% of the patients. Conclusions: The findings of this study highlight the usefulness of GCS and PSS systems for predicting severity of OP poisoning. Identification of severity at an early stage followed by prompt treatment can prevent deaths. Our study did not find any association between pseudocholinesterase levels at admission and severity of OP poisoning.
An attention‐based category‐aware GRU model for the next POI recommendation

With the continuous accumulation of users' check‐in data, we can gradually capture users' behavior patterns and mine users' preferences. Based on this, the next point‐of‐interest (POI) recommendation has attracted considerable attention. Its main purpose is to simulate users' behavior habits of check‐in behavior. Then, different types of context information are used to construct a personalized recommendation model. However, the users' check‐in data are extremely sparse, which leads to low performance in personalized model training using recurrent neural network. Therefore, we propose a category‐aware gated recurrent unit (GRU) model to mitigate the negative impact of sparse check‐in data, capture long‐range dependence between user check‐ins and get better recommendation results of POI category. We combine the spatiotemporal information of check‐in data and take the POI category as users' preference to train the model. Also, we develop an attention‐based category‐aware GRU (ATCA‐GRU) model for the next POI category recommendation. The ATCA‐GRU model can selectively utilize the attention mechanism to pay attention to the relevant historical check‐in trajectories in the check‐in sequence. We evaluate ATCA‐GRU using a real‐world data set, named Foursquare. The experimental results indicate that our ATCA‐GRU model outperforms the existing similar methods for next POI recommendation.
Isotopic Composition of Precipitation in a Southeastern Region of Brazil during the Action of the South Atlantic Convergence Zone

The use of stable isotopes of hydrogen and oxygen is a tool widely used to trace water paths along the hydrological cycle, providing support for understanding climatic conditions in different spatial scales. One of the main synoptic scale events acting in southeastern Brazil is the South Atlantic Convergence Zone (SACZ), which causes a large amount of precipitation from southern Amazonia to southeastern Brazil during the southern summer. In order to determine the isotopic composition of precipitation during the action of SACZ in São Francisco Xavier in southeastern Brazil, information from the Weather Forecasting and Climate Studies Center of the National Institute for Space Research (CPTEC) was used regarding SACZ performance days, the retrograde trajectories of the HYSPLIT model, and images from the GOES-16 satellite, in addition to the non-parametric statistical tests by Spearman and Kruskal–Wallis. A high frequency of air mass trajectories from the Amazon to southeastern Brazil was observed when the SACZ was operating. During the SACZ events, the average isotopic composition of precipitation was more depleted, with a δ18O of −9.9‰ (±2.1‰), a δ2H of −69.3‰ (±17.9‰), and d-excess of 10.1‰ (±4.0‰). When disregarding the SACZ performance, the annual isotopic composition can present an enrichment of 1.0‰ for δ18O and 8.8‰ for the δ2H. The long-term monitoring of trends in the isotopic composition of precipitation during the SACZ events can assist in indicating the evapotranspiration contribution of the Amazon rainforest to the water supply of southeastern Brazil.
The influence of school and family education towards a professional career: the case of the wine industry in two emerging economies

ABSTRACT This study examines the role of school and family education in supporting individuals’ career path, specifically in the wine and wine tourism environments. To gain a more in-depth understanding of this dimension, key underpinnings of social learning and family social capital theory are considered. Owners and managers of 32 wineries from two emerging economies participated through face-to-face interviews. While there was general agreement regarding the significance of school education, the relevance of family education was perceived more strongly, including in instilling effort, values and codes of conduct, thus, influencing participants’ journey towards a managerial or ownership role in the wine industry. Assimilating earlier stages of one’s life, vicarious learning, self-efficacy, and family social capital were manifested through intrinsic principles, and were further enhanced through learning gained via work experience and continuous knowledge gathering. A model highlighting links between the empirical findings and the above theoretical underpinnings is proposed.
Protective Potential of Lycopene Enriched Tomato Extract against Dexamethasone Induced Hepatic and Renal Damage in Mice

Aim: The present study was carried out to determine the protective potential of Lycopene enriched tomato extract (LycT) against hepatic and renal damage caused in mice by dexamethasone administration. Study Design: Male LACA mice were randomly divided into four treatment groups (n=6-7 animals per group) depending upon the treatment they received. Group I (control) animals served as control and were orally administered with olive oil (vehicle) thrice a week for five weeks. Group II (DEX) animals were intraperitoneallly (i.p.) administered with dexamethasone at a dose of 5 mg/kg b.w. on alternate days for three weeks. Group III (LycT) animals were orally (p.o.) administered with LycT at a dose of 5 mg/kg b.w. on alternate days for five weeks. Group IV (LycT+DEX) animals were coadministered with LycT (p.o.) and dexamethasone (i.p.) according to the above mentioned dose regimen Results: Dexamethasone caused hepatic and renal damage as evident from disturbed histoarchitecture, deranged levels of organ function markers (alkaline phosphatase, serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, total and direct Original Research Article Koul et al.; AJRB, 8(3): 1-23, 2021; Article no.AJRB. 66104 2 bilirubin, urea, creatinine) and enhanced level of cell damage (lactate dehydrogenase) and oxidative stress (lipid peroxidation) markers. Increased blood glucose level, decreased hepatic glycogen level along with inhibited activities of enzymes involved in glycolysis (hexokinase, phosphoglucoisomerase) indicated altered glucose metabolism in DEX group. The mitigation in histoarchitectural alterations, cell damage and oxidative stress markers, improved levels of organ function markers, blood glucose level along with ramped up antioxidant defense system indicated the protective potential of LycT against dexamethasone induced ill effects. Conclusions: These results point towards beneficial effects of LycT against dexamethasone induced damage to hepatic and renal tissues in mice.
