Automatic filtering algorithm for imbalanced classification

The imbalanced data set has been reported to hinder the classification performance of many machine learning algorithms on both accuracy and speed. But extremely imbalanced data sets (3∼5% positive samples) are common for many applications, such as multimedia semantic classification. In this paper, we propose a novel algorithm to automatically remove samples that have no or negative effects on classifier training for imbalanced training data sets. By using our algorithm, most easy-to-classify dominant-class samples in imbalanced training set will be eliminated automatically. As a result, the ratio of minority class samples is increased significantly, making it more suitable for classification algorithms. Experiments show that our algorithm can keep the classification accuracy of SVM, and decrease the training time dramatically.
Effect of P2Y12 Inhibitors on Survival Free of Organ Support Among Non–Critically Ill Hospitalized Patients With COVID-19

Platelets represent a potential therapeutic target for improved clinical outcomes in patients with COVID-19.To evaluate the benefits and risks of adding a P2Y12 inhibitor to anticoagulant therapy among non-critically ill patients hospitalized for COVID-19.An open-label, bayesian, adaptive randomized clinical trial including 562 non-critically ill patients hospitalized for COVID-19 was conducted between February 2021 and June 2021 at 60 hospitals in Brazil, Italy, Spain, and the US. The date of final 90-day follow-up was September 15, 2021.Patients were randomized to a therapeutic dose of heparin plus a P2Y12 inhibitor (n = 293) or a therapeutic dose of heparin only (usual care) (n = 269) in a 1:1 ratio for 14 days or until hospital discharge, whichever was sooner. Ticagrelor was the preferred P2Y12 inhibitor.The composite primary outcome was organ support-free days evaluated on an ordinal scale that combined in-hospital death (assigned a value of -1) and, for those who survived to hospital discharge, the number of days free of respiratory or cardiovascular organ support up to day 21 of the index hospitalization (range, -1 to 21 days; higher scores indicate less organ support and better outcomes). The primary safety outcome was major bleeding by 28 days as defined by the International Society on Thrombosis and Hemostasis.Enrollment of non-critically ill patients was discontinued when the prespecified criterion for futility was met. All 562 patients who were randomized (mean age, 52.7 [SD, 13.5] years; 41.5% women) completed the trial and 87% received a therapeutic dose of heparin by the end of study day 1. In the P2Y12 inhibitor group, ticagrelor was used in 63% of patients and clopidogrel in 37%. The median number of organ support-free days was 21 days (IQR, 20-21 days) among patients in the P2Y12 inhibitor group and was 21 days (IQR, 21-21 days) in the usual care group (adjusted odds ratio, 0.83 [95% credible interval, 0.55-1.25]; posterior probability of futility [defined as an odds ratio <1.2], 96%). Major bleeding occurred in 6 patients (2.0%) in the P2Y12 inhibitor group and in 2 patients (0.7%) in the usual care group (adjusted odds ratio, 3.31 [95% CI, 0.64-17.2]; P = .15).Among non-critically ill patients hospitalized for COVID-19, the use of a P2Y12 inhibitor in addition to a therapeutic dose of heparin, compared with a therapeutic dose of heparin only, did not result in an increased odds of improvement in organ support-free days within 21 days during hospitalization.ClinicalTrials.gov Identifier: NCT04505774.

OP19 – 2435: Prognostic significance of EEG in infantile spasms

Objective To assess the prognostic value of initial characteristics of EEG for primary and long-term outcome in infantile spasms, and correlation between hypsarrhythmia duration/resolution/normalization during treatment and long-term outcome. Methods In the cohort of 180 infants with infantile spasms treated in the Institute with vigabatrin from the beginning of 1996 to the end of 2010. the analysis of the impact of EEG features on the first EEG to primary outcome (cessation of spasms) was done. Also the impact of initial EEG characteristics and after 6 weeks of treatment on long-term outcome was investigated after follow up period of 2.4 to 18.9 years (M=10.64; SD=4.40). The duration of hypsarrhythmia was assessed with standard statistical methods and logistic regression analysis. Results In the initial EEG hypsarithmia occurred more frequently in non-responders (χ 2 (1)=3.789, p=0.052), whereas modified hypsarithmia occurred more frequently in responders (χ 2 (1)=4.282, p=0.039). Odds for favorable long-term outcome in patient with initial hypsarrhythmia was 0.45 and with initial modified hypsarrhythmia was 1.05. After 6 weeks of treatment, odds for favorable long-term outcome in patient with hypsarrhythmia was 0.17 and with normal EEG was 1.45 (χ 2 (3)=15.261, p=0.002). Duration of hypsarrhythmia did not statistically influence the long-term outcome assessed as divided (χ 2 (2)=3.647, p=0.161) or continuous variable. Conclusion Features of hypsarrhythmia on initial EEG did not significantly determine the primary or long-term outcome in our patients. The duration of hypsarrhythmia did not correlate with the long-term outcome. But the normalization of EEG was associated with cessation of spasms, and reactivity to therapy with good outcome. That points to the complex interplay between duration of hypsarrhythmia and basic etiologic condition in the prognosis of IS.
Is OASIS Effective in Predicting Rehospitalization for Home Health Care Elderly Patients?

Using the Outcome and Assessment Information Set (OASIS), this study examined the feasibility of using OASIS items to identify direct and indirect factors contributing to rehospitalization among elderly patients receiving home health care. The outcomes revealed that being male, having a median level of cognitive impairment, a lower level of functional ability, and the absence of support, such as environmental support, psychosocial support, or facilitated medical care directly contributed to rehospitalization. While being older, obese, having a poorer clinical status, receiving ADL and/or IADL and less frequent informal care contributed to rehospitalization indirectly through decreased functional ability. Home health care providers may take full advantage of OASIS data, assessing both the direct and indirect factors leading to rehospitalization to identify patients at risk and intervene when needed.

1,094,933. Producing self-crimping polypropylene filaments. IMPERIAL CHEMICAL INDUSTRIES Ltd. April 4, 1966 [April 20, 1965], No. 16543/65. Heading B5B. Self-crimping composite polypropylene filaments are produced by conjugate melt spinning of two propylene polymers having the same intrinsic viscosity, but different molecular weight distributions, and subsequently drawing and/or relaxing the tension in the filaments. The " dispersion coefficient " of at least one component must be at least 6À5 and the dispersion coefficients of the polymers may differ by at least 0À5. The component polymers may have a viscosity of at least 1À0. The unrelaxed spun filaments may be drawn 2-4 times their original length and the drawing may be effected by means of a snubbing surface heated to not over 100 C. The drawn filaments may be heat treated on the draw roll which is maintained at a temperature of up to 100 C. The crimped filaments may be stabilized by heat treatment at 100.. 140 C. The " dispersion coefficient ", which is an expression of the molecular weight distribution of a propylene polymer is defined as the ratio of the weight average molecular weight to the number average molecular weight of the polymer, these values being determined by light scattering and membrane osmometry techniques described in detail in the Specification. The intrinsic viscosities of the polymer are measured in decalin solution at 135 C., the units of intrinsic viscosity being decilitres/gram.

Human development and cross-border acquisitions

Abstract We examine the role of human development in US companies' decisions to engage in cross-border acquisitions. Utilizing the human development index (HDI) published by the United Nations Development Program (UNDP), we find that US firms make acquisitions in countries with strong HDI levels. Alternative factors such as institutional quality, life expectancy, telephone usage and school enrolments also have a positive influence on the cross-border acquisition decision. Further, we find a positive relationship between cross-border mergers and acquisitions (M&As) and HDI rankings relative to the United States. Our findings contribute to the literature that seeks to explain why so little capital flows from developed to developing economies.
Pyschometric properties and the factor structure of the Spanish version of the cognitive adaptability(MAC) scale.

In the context of entrepreneurship, cognitive adaptability is a key competence. Thus, researchers in this field are making an effort to find instruments to measure this ability in a way that allows us to predict success in the context of enterprise creation or intention. We conducted a series of exploratory and confirmatory analyses of the cognitive adaptability scale (MAC), using a sample of Spanish (N = 494), in addition to the reliability and validity analyses. We found that a three-factor solution of the MAC best fit the data. The reliability coefficients of consistency were acceptable. The validity of the MAC was confirmed by its correlation with Need for Cognition (NFC). The NFC measures the degree to which individuals enjoy cognitive activity. The present study suggests that more studies are needed in different contexts that would allow the structure of cognitive adaptability to be validated, improved or modified.
Fault detection system for distributed generation converters

In this paper, a fault detector algorithm for detecting voltage disturbances is proposed and analyzed. This method is based on the voltage characteristics instead of the current amplitude that is the most common approach in power distribution electrical systems. The proposed system uses a dual quadrature signal generator for each voltage component in a stationary reference frame to extract the positive- and negative-sequence components of the voltage. Besides a frequency-locked loop is used to estimate the voltage frequency. All these information is compared with the nominal values by means of hysteresis comparators. As a result, a fast and reliable fault detector system is obtained. Results of simulations and experiments are presented to illustrate the feasibility and performance of the proposed schemes.

The invention also relates to a device for carrying out the method.
A NEW MULTIPLICATIVE DECOMPOSITION FOR THE FOSTER-GREER-THORBECKE POVERTY INDICES

This paper identifies a multiplicative decomposition for the Foster-Greer-Thorbecke poverty indices as a product of the three components which should be involved in every poverty index: the incidence of poverty, measured by the headcount ratio, the intensity of poverty, measured by the aggregate income gap ratio and the inequality among the poor measured by an increasing transformation of the corresponding inequality index of the Generalized Entropy family. Then, taking data from the Spanish Household Budget Surveys (SHB) as a basis we show the advantages and possibilities of this framework in regard to completing and detailing information in studies of poverty over time.

Performance comparison of reconstruction algorithms in discrete blind multi-coset sampling

This paper investigates the performance of different reconstruction algorithms in discrete blind multi-coset sampling. Multi-coset scheme is a promising compressed sensing architecture that can replace traditional Nyquist-rate sampling in the applications with multi-band frequency sparse signals. The performance of the existing compressed sensing reconstruction algorithms have not been investigated yet for the discrete multi-coset sampling. We compare the following algorithms - orthogonal matching pursuit, multiple signal classification, subspace-augmented multiple signal classification, focal under-determined system solver and basis pursuit denoising. The comparison is performed via numerical simulations for different sampling conditions. According to the simulations, focal under-determined system solver outperforms all other algorithms for signals with low signal-to-noise ratio. In other cases, the multiple signal classification algorithm is more beneficial.
Development of microsatellite markers for Peristenus digoneutis (Hymenoptera: Braconidae), a key natural enemy of tarnished plant bugs

The introduced European parasitoid Peristenus digoneutis is a key biocontrol agent of lygus bug pests in agricultural crops in the Northeastern USA. Changes in cultural practices and reduction of alfalfa culture have significantly reduced its abundance in its native range from historic levels. Of 48 microsatellite loci isolated from P. digoneutis genome using 454 pyrosequencing, 24 were retained based upon consistent amplification. Sixteen loci exhibited polymorphism in populations sampled in France and the USA. The number of alleles ranged from 2 to 9. The observed heterozygosity (H o) and the expected heterozygosity (H e) varied from 0.043 to 0.710 and from 0.103 to 0.728, respectively. Most loci conformed to Hardy–Weinberg equilibrium with the exclusion of five loci. These polymorphic loci will be valuable for population genetic studies and genetic conservation for P. digoneutis.
TU-C-BRB-11: In Vitro Dose Enhancement from Gold Nanoparticles under Different Clinical MV Photon Beam Configurations

Purpose: To quantify the relative in vitro dose enhancement due to the presence of goldnanoparticles (GNPs) in a clinical 6 MV beam. It is expected that depths and delivery modes that produce larger proportions of low energy photons will have a larger effect on cell samples containing GNP. Methods: HeLa cells were combined with 50 nm GNPs at a concentration of 0 or 0.05 mg/ml. The cells were irradiated in clinical solid water at depths of 1.5, 5, 10, 15 and 20 cm (SAD setup). Conventional beams with square aperture sizes 5, 10 and 15 cm at isocenter, IMRT and flattening filter free (FFF) beams were used. DNA double strand breaks (DSBs) were evaluated by H2AX staining. Results: Statistically significant dose enhancement was observed for all depths and delivery modes. Dose enhancement ratios varied between 1.1 and 1.7. Relative to the shallowest depth, dose enhancement was observed to increase as a function of increasing depth for all deliveries. For the conventional (open field) delivery, dose enhancement was seen to increase as a function of field size. The IMRT delivery chosen for this study did not significantly increase the dose enhancement at each depth, but did in the aggregate. For FFF delivery, a substantial increase in gH2AX foci was found, relative to the conventional field delivery. Without GNP, no enhancement was observed as a function of depth, indicating that the enhancing effect with GNP is due to the change in energy spectrum under each delivery condition. Conclusions: The measured relative dose enhancement validates the theoretically predicted trends in dose enhancement as a function of depth and delivery mode for a clinical MV beam. The results of this study open new possibilities for the clinical development of goldnanoparticle aided radiation therapy.

El Barrenador de la SemillaCaryedon serratusOliver (Coleoptera: Bruchidae) en Tamarindo en el Trópico Seco de México — Una Revisión

Abstract. Tamarind, Tamarindus indica L., is an economically important crop in the dry tropical region of Western Mexico. For more than a decade, damage caused by an insect borer in seeds has been observed. Since 2006, taxonomical identification, biology, hosts, and integrated management of the insect have been studied. In this review, current knowledge of the tamarind seed borer is presented. The beetle is 4 to 6 mm long, with a brown-colored body with pubescence, large hind legs, and large serrated antennae. Its elytra do not cover the last abdominal segments. The larvae are 7 to 8 mm long, pinkish-white in color, and slightly mobile. In the Western region of Mexico, tamarind is the main host. The insect oviposits on different legumes; however, only on tamarind (followed by peanut and chickpea) can it complete its life cycle. According to these characteristics, the insect was identified as Caryedon serratus Oliver and affects tamarind pods at pre-and postharvest. Its control should be oriented to damage...
