A compressed sensing approach to block-iterative equalization: connections and applications to radar imaging reconstruction

A proliferacao de sistemas sub-determinados trouxe a tona uma gama de novas solucoes algoritmicas, baseadas no sensoriamento compressivo (CS) de dados esparsos. As recursoes do tipo greedy e de limitacao iterativa para CS se apresentam comumente como um filtro adaptativo seguido de um operador proximal, nao muito diferente dos equalizadores de realimentacao de decisao iterativos em blocos (BI-DFE), em que um decisor explora a estrutura do sinal de constelacao. A partir da esparsidade intrinseca presente na modulacao de sinais no contexto de comunicacoes, a interferencia entre blocos (IBI) pode ser abordada utilizando-se o conceito de CS, onde a realimentacao otima de simbolos detectados e realizada de forma adaptativa. O novo DFE se apresenta como um esquema mais eficiente de reestimacao, baseado na atualizacao por minimos quadrados recursivos (RLS). Sempre que possivel estas recursoes sao propostas via formulacao linear no sentido amplo, o que reduz ainda mais o erro medio quadratico minimo (MMSE) em comparacao com abordagens tradicionais. Alem de maximizar a taxa de transferencia de informacao, o novo algoritmo exibe um desempenho significativamente superior quando comparado aos metodos existentes. Tambem mostraremos que um equalizador BI-DFE formulado adequadamente se torna um poderoso algoritmo de CS. O novo algoritmo CS-BDFE apresenta convergencia e deteccao aprimoradas, quando comparado a metodos de primeira ordem, superando as recursoes de Passagem de Mensagem Aproximada para Complexos (CAMP). Os meritos das novas recursoes sao ilustrados atraves de um modelo tridimensional para radares MIMO recentemente proposto, onde o algoritmo CAMP falha em aspectos importantes de medidas de desempenho.
Notes on the diet of adult Yellow Catfish Aspistor luniscutis (Pisces: Siluriformes) in northern Rio de Janeiro State, southeastern Brazil

Diet of adult specimens of Yellow Catfish Aspistor luniscutis (Valenciennes, 1840) was determined through stomach contents analysis. The specimens were target of commercial gillnet fisheries in northern Rio de Janeiro State, southeastern Brazil. In this region, A. luniscutis is a generalist benthophagous feeder, consuming most available prey species with crustaceans, especially penaeid shrimps, brachyuran crabs, and sciaenid fish dominating.
Time of Emergence of Eight Weed Species

Under irrigated field conditions at Prosser, WA, Russian thistle [Salsola kali (L.) var. tenuifolia Tausch. ♯3 SASKR] began to emerge by mid-March each year and usually had completed its emergence by May 1. Common lambsquarters (Chenopodium album L. ♯ CHEAL) was the next to appear, usually during the third or fourth week of March. Barnyardgrass [Echinochloa crus-galli (L.) Beauv. ♯ ECHCG], redroot pigweed (Amaranthus retroflexus L. ♯ AMARE), hairy nightshade (Solarium sarrachoides Sendt. ♯ SOLSA), black nightshade (5. nigrum L. ♯ SOLNI), eastern black nightshade (S. ptycanthum Dun.), and cutleaf nightshade (S. triflorum Nutt. ♯ SOLTR) generally began to emerge during the first 2 weeks of April and emergence generally peaked mid-April to mid-May. Russian thistle and cutleaf nightshade had the most restricted emergence patterns, whereas seedlings of common lambsquarters, redroot pigweed, hairy nightshade, and black nightshade emerged each month from April through September. Shallow tillage at monthly intervals increased the overall emergence of common lambsquarters, redroot pigweed, black nightshade, and eastern black nightshade; decreased the emergence of barnyardgrass; and had no effect on the emergence of Russian thistle, cutleaf nightshade, or hairy nightshade.

The evolution of power in the global coffee value chain and production network

The configurations of global value chains and production networks are constantly changing, leading to new trajectories and geographical distributions of value creation and capture. In this article, we offer a 40-year evolutionary perspective on power and governance in the global coffee value chain and production network. We identify three distinct phases that are characterised by different power dynamics, governance setups and distributional configurations. We find that the kinds of power exercised along the coffee chain have changed, but also that the underlying power inequities between Northern buyers and Southern producers have remained fundamentally unaltered.
Thermodynamic Analysis of Cascade Refrigeration System Using R12-R13, R290-R23 and R404A-R23

— The Montreal protocol and Kyoto protocol underlined the need of substitution of CFC’s and HCFC’s due to their adverse impact on atmospheric ozone layer which protects earth from U.V rays. The CFCs have been entirely ruled out since 1995 and a long-term basis HCFCs must be replaced by 2020. All this events motivated HFC refrigerants which are harmless to ozone layer. In this paper thermodynamic analysis of cascade refrigeration system has been done using three different refrigerant pairs R13-R12, R290-R23, and R404A-R23. Effect of various operating parameters i.e. evaporator temperature, condenser temperature, temperature difference in cascade condenser and low temperature cycle condenser temperature on performance parameters viz. COP, exergetic efficiency and refrigerant mass flow ratio have been studied. Thermodynamic analysis shows that out of three refrigerant pairs R12-R13, R290-R23 and R404A-R23 the COP of R290-R23 refrigerant pair is highest.
Political, Legal and Institutional Aspects of the Policy of the Management of Diaspora in the Republic of Moldova

The article is devoted to the study of political, legal and institutional aspects of the policy of diaspora management in the Republic of Moldova. The authors consider that the Moldovan authorities are trying to develop a coherent state policy on the Diaspora through an integrated approach. This is reflected in the legislative and institutional framework of the state policy in the field of Diaspora. As the results of sociological research, Moldovan migrants do not actively participate in the activity of Diaspora organizations. The authors note that in order to develop an effective management policy Diaspora in the Republic of Moldova, the creation of institutions is necessary to ensure the preservation and development of the Diaspora; development of a strategy of interaction with state institutions as the country of residence, and the “title” of the state; development of legal acts on the Diaspora, as well as laws and policies on management of the diaspora processes. These measures will provide creation and strengthening of a stable platform for cooperation between the state and the Moldovan diaspora, the active participation of the diaspora in the economic and political life of the Republic of Moldova.
Short-term outcome of laparoscopic surgery versus open surgery on colon carcinoma: A meta-analysis.

OBJECTIVE The aim of this article is to compare the oncological outcomes of laparoscopic and open resection for colon cancer. METHOD Search the publications on comparison the efficacy of laparoscopic surgery comparison with open surgery in treatment outcomes of colon cancer to May, 2018. After rigorous reviewing on quality, the data was extracted from eligible trials. All trials analyzed the summary hazard ratios (HRs) of the endpoints of interest, including intraoperative and postoperative outcomes. RESULTS A total of 13 trials were met our inclusion criteria. With the pooled result of duration of surgery indicate that laparoscopic surgery was associated with a trend longer operate time (SMD = 0.58, 95% CI 0.17-0.99; P＝0.005) , shorter length of hospital stay (SMD = -0.57, 95% CI -1.00--0.15; P = 0.008) and postoperative hospital stay (SMD = -0.66, 95% CI -0.99--0.33; P = 0.0001) , less blood loss (SMD = -0.68, 95% CI -1.12--0.24; P = 0.002), shorter incision length (SMD = -4.61, 95% CI -5.79--3.43; P＜＝0.00001 and less wound infection (OR = 0.30, 95% CI 0.13-0.67; P = 0.004). However, there were no differences in the number of lymph nodes harvested (P = 0.17), ileus (P = 0.91), pulmonary infection (P = 0.22) and postoperative complications (P = 0.24) between the 2 groups. CONCLUSION Laparoscopic surgery had similar intraoperative and postoperative recovery parameters to those of the patients in the open group. The patients treated with laparoscopic had a trend longer operate time, shorter hospital stays, less intra-operative blood loss, faster recovery and lower incidence of wound infection. Whether it can be expected to be a standardization operation method for colon carcinoma still need more random clinical trials to be verified.
ON THE MYTH OF PARENTAL ALIENATION SYNDROME (PAS) AND THE DSM-5

224 he Magistrates of the Group of Experts on Domestic and Gender Violence of the Spanish General Council of the Judiciary (CGPJ), at a meeting held on October 13, 2016 approved the Guidelines to Organic Law 1/2004, of December 28, on Measures of Integral Protection against Gender Violence (Carmona et al., 2016). In chapter X of these guidelines, four pages of comments are included about what is known as Parental Alienation Syndrome (PAS), under the heading “Other aspects to consider in the Jurisdictional Activity”. We submit to analysis the above mentioned chapter, because –in its brevity– it is intended to dictate doctrine in the forensic field and may serve our analysis of the myth about the non-existence of the PAS phenomenon, based, among other arguments, on its lack of inclusion in the diagnostic classifications, a specific issue on which this article focuses. The problem is of great interest for the work of all legal actors affected by these issues, given the prestige of the CGPJ and the possible implications of these guidelines at the level of legal and forensic practice.

Production, characterization and optimization of fermented tomato and carrot juices by using Lysinibacillus sphaericus isolate -

Fermentation of tomato and carrot juices was carried out with a native isolate of Lysinibacillus sphaericus. Initial screening showed that total phenolics, antioxidants and titratable acidity were higher in both the fermented juices than respective un-fermented controls. Better fermentation characteristics were found in fermented tomato juice at 37oC (pH 5.8, TA% 0.38 and cell viability of 7.8 x 107 CFU/mL) than those of fermented carrot juice (pH 5.5, TA% 0.30 and cell viability of 6.9 x 107 CFU/mL). Hence, fermentation of tomato juice was optimized by Central Composite Design using temperature, pH, incubation time and sucrose concentrations as critical parameters. The optimized conditions for fermentation of tomato juice were determined to be pH 6.2, temperature of 37oC, inoculum size of 7.58 log CFU/mL, sucrose concentration of 10% and fermentation for 24 h. The antimicrobial activity of the fermented tomato juice against Bacillus cereus MTCC 7190 was better (inhibition zone of 10 mm) than the fermented carrot juice (8 mm). The cell viability of Lys. sphericus at 4oC for 6 weeks was better in tomato juice (0.9 x 106) than in the carrot juice (0.6 x106 CFU/mL). Fermented juices exhibited good sensory attributes and could possibly be used as probiotic drinks.
Capital Controls and Currency Crises Revisited: A Political Economy Analysis

Abstract Recent empirical studies have reached mixed results on the effects of capital controls and currency crises. We argue that this relationship is likely to depend both on whether controls are primarily on capital inflows or outflows and on the stability of the government. Using the disaggregated data on capital controls using the newly developed disaggregated data on capital controls for a sample of 56 countries for a sample of 56 countries over the period 1995–2015, we discover some interesting patterns on capital controls and political stability that there is a vanishing middle in terms of the extent of controls and that the use of controls is positively associated with government stability. We also find strong support for the proposition that controls on outflows are positively associated with the probability of currency crises especially under less stable governments, while controls on capital inflows reduce the risks of currency crises, especially for more stable governments.
Seasonal variations in infiltrability of moss‐dominated biocrusts on aeolian sand and loess soil in the Chinese Loess Plateau

Biocrust effects on soil infiltration have attracted increasing attention in dryland ecosystems, but their seasonal variations in infiltrability have not yet been well understood. On the Chinese Loess Plateau, soil infiltrability indicated by saturated hydraulic conductivity (Ks) of biocrusts and bare soil, both on aeolian sand and loess soil, was determined by disc infiltrometer in late spring (SPR), midsummer (SUM), and early fall (FAL). Then their correlations with soil biological and physiochemical properties and water repellency index (RI) were analysed. The results showed that the biocrusts significantly decreased Ks both on sand during SPR, SUM, and FAL (by 43%, 66%, and 35%, respectively; P < .05) and on loess (by 42%, 92%, and 10%, respectively; P <.05). As compared with the bare soil, the decreased Ks in the biocrusted surfaces was mostly attributed to the microorganism biomass and also to the increasing content of fine particles and organic matter. Most importantly, both the biocrusts and bare soil exhibited significant (F ≥ 11.89, P ≤ .003) seasonal variations in Ks, but their patterns were quite different. Specifically, the Ks of bare soil gradually decreased from SPR to SUM (32% and 42% for sand and loess, respectively) and FAL (29% and 39%); the Ks of biocrusts also decreased from SPR to SUM (59% and 92%) but then increased in FAL (36% and 588%). Whereas the seasonal variations in Ks of the biocrusts were closely correlated with the seasonal variations in RI, the RI values were not high enough to point at hydrophobicity. Instead of that, the seasonal variations of Ks were principally explained by the changes in the crust biomass and possibly by the microbial exopolysaccharides. We conclude that the biocrusts significantly decreased soil infiltrability and exhibited a different seasonal variation pattern, which should be carefully considered in future analyses of hydropedological processes.
Regional Widening of Tropical Overturning: Forced Change, Natural Variability, and Recent Trends

The width of the tropical Hadley circulation (HC) has garnered intense interest in recent decades, owing to the emerging evidence for its expansion in observations and models and to the anticipated impacts on surface climate in its descending branches. To better clarify the causes and impacts of tropical widening, this work generalizes the zonal mean HC to the regional level by defining meridional overturning cells (RC) using the horizontally divergent wind. The edges of the RC are more closely connected to surface hydroclimate than more traditional metrics of regional tropical width (such as the sea level pressure ridge) or even than the zonal mean HC. Simulations reveal a robust weakening of the RC in response to greenhouse gas increases, along with a widening of the RC in some regions. For example, simulated widening of the zonal mean HC in the Southern Hemisphere appears to arise in large part from regional overturning anomalies over the Eastern Pacific, where there is no clear RC. Unforced interannual variability in the position of the zonal mean HC edge is associated with a more general regional widening. These distinct regional signatures suggest that the RCs may be well suited for the attribution of observed circulation trends. The spatial pattern of regional meridional overturning trends in reanalyses corresponds more closely to the pattern associated with unforced interannual variability than to the pattern associated with CO2 forcing, suggesting a large contribution of natural variability to the recent observed tropical widening trends.
The Theory of the Transnational Corporation at 50

The paper briefly summarises the historical evolution of transnational corporations (TNCs) and their activities. It then introduces the major theories developed to explain the TNC. There is an attempt to place the theories historically, within the context of the socio-economic conditions and of the relevant economic ideas in which they were developed. The following theories are discussed: Hymer's, market power and control; Vernon's international product life cycle; the internalisation theory; Dunning's eclectic framework based on Ownership, Location, and Internalisation (OLI) advantages; The Scandinavian School; the evolutionary approaches of Cantwell and of Kogut and Zander; the New Trade theory applied to the TNC; the role of nation-states in the strategic behaviour of TNCs. There are some critical comments at the end of each presentation. A brief analysis of key elements in the theories, their differences and commonalities follows. It is pointed out that the pattern of development shows tensions between the following interconnected elements: (1) contents and methods of interest to Business Schools and to Economics Departments; (2) static versus dynamic approaches; (3) emphasis on efficiency versus strategic elements; (4) strategies towards rivals as well as towards other players in the economic system such as labour, governments and suppliers; (5) single- versus multi-disciplinary approaches; and micro versus macro approaches.
Sign preservation analysis of orthogonal greedy algorithms

We bring a contribution to the exact recovery theory of a non-negative K-sparse vector from noisy linear measurements under the condition mu<1/(2K-1), where mu denotes the mutual coherence. While it is known that Orthogonal Matching Pursuit (OMP) and Orthogonal Least Squares (OLS) identify the true support in K iterations, we prove that the weights of the selected atoms have the correct sign in the best current approximation at any of the K iterations. Therefore, OMP and OLS identify with their sign-aware versions, which allows us to establish for the first time an exact support recovery property based on mutual coherence for non-negative versions of OMP and OLS.
Effects of Elevated CO2 on Wheat Yield: Non-Linear Response and Relation to Site Productivity

Elevated carbon dioxide (eCO2) is well known to stimulate plant photosynthesis and growth. Elevated carbon dioxide’s effects on crop yields are of particular interest due to concerns for future food security. We compiled experimental data where field-grown wheat (Triticum aestivum Linnaeus) was exposed to different CO2 concentrations. Yield and yield components were analyzed by meta-analysis to estimate average effects, and response functions derived to assess effect size in relation to CO2 concentration. Grain yield increased by 26% under eCO2 (average ambient concentration of 372 ppm and elevated 605 ppm), mainly due to the increase in grain number. The response function for grain yield with CO2 concentration strongly suggests a non-linear response, where yield stimulation levels off at ~600 ppm. This was supported by the meta-analysis, which did not indicate any significant difference in yield stimulation in wheat grown at 456–600 ppm compared to 601–750 ppm. Yield response to eCO2 was independent of fumigation technique and rooting environment, but clearly related to site productivity, where relative CO2 yield stimulation was stronger in low productive systems. The non-linear yield response, saturating at a relatively modest elevation of CO2, was of large importance for crop modelling and assessments of future food production under rising CO2.
Qualitative exploration of career adaptability of Turkish adolescents

This article reports on a qualitative study that uses a phenomenological approach to investigate the differences between adolescents with high and low career adaptability levels, regarding adaptive strategies and needs. The sample included students categorized as above the 75th percentile and in the bottom 25th percentile according to their scores on the Career Adapt-Abilities Scale. The data were gathered from 20 high school students (12 male and 8 female) from Ankara, Turkey, using career construction interviews. A content analysis revealed that exploration (self and occupations), persistence, and inquisitiveness were frequently observed in the high career adaptability group. On the other hand, lack of persistence, lack of confidence, and emotion-focused problem solving were prominent in the low career adaptability group. The results suggest the need for career education programs in schools that promote confidence and problem-solving skills for Turkish adolescents, especially those low on adaptability.
