Comparing Random-based and k-Anonymity-Based Algorithms for Graph Anonymization

Recently, several anonymization algorithms have appeared for privacy preservation on graphs. Some of them are based on random-ization techniques and on k-anonymity concepts. We can use both of them to obtain an anonymized graph with a given k-anonymity value. In this paper we compare algorithms based on both techniques in orderto obtain an anonymized graph with a desired k-anonymity value. We want to analyze the complexity of these methods to generate anonymized graphs and the quality of the resulting graphs.

Is bank debt special for the transmission of monetary policy? Evidence from the stock market

We combine existing balance sheet and stock market data with two new datasets to studywhether, how much, and why bank lending to firms matters for the transmission of monetarypolicy. The first new dataset enables us to quantify the bank dependence of firms precisely,as the ratio of bank debt to total assets. We show that a two standard deviation increase inthe bank dependence of a firm makes its stock price about 25% more responsive to monetarypolicy shocks. We explore the channels through which this effect occurs, and find that thestock prices of bank-dependent firms that borrow from financially weaker banks display astronger sensitivity to monetary policy shocks. This finding is consistent with the banklending channel, a theory according to which the strength of bank balance sheets mattersfor monetary policy transmission. We construct a new database of hedging activities andshow that the stock prices of bank-dependent firms that hedge against interest rate riskdisplay a lower sensitivity to monetary policy shocks. This finding is consistent with aninterest rate pass-through channel that operates via the direct transmission of policy ratesto lending rates associated with the widespread use of floating-rates in bank loans and creditline agreements.

1st datings of ammonite-bearing Bajocian suites from Caucasus (Georgia) - K-Ar ages of volcanic hornblendes

Volcanic flows and tuffs interbedded with ammonite-bearing sediments directly correlatable with the stratotype section of the Bajocian stage have been dated for the first time within the Caucasus area. Three samples, each from a different section, allowed separation of well-preserved brown hornblende; these are considered reliable geochronometers in a region where subsequent volcanic activity occurred. The dated separates are V139: a volcanic layer probably near the base, V142 another layer near the top of the Lower Bajocian substage; V141 a boulder from a latest Bajocian volcanic conglomerate. From bottom to top, apparent ages at 173.5 +/- 2.6, 164.8 +/- 2.5 and 167.1 +/- 1.9 Ma (analytical uncertainty, 95% confidence level) respectively, can be calculated. The consistency of the results is obtained if the dated boulder is interpreted as derived from an underlying layer, The Bajocian-Bathonian boundary is much younger than commonly accepted and younger than 164 Ma.

Absor����o de N, P e K por esp��cies de adubos verdes cultivadas em diferentes ��pocas e densidades num latossolo vermelho-escuro argiloso sob cerrados

Popula����es espec��ficas de plantas e a ��poca de semeadura podem promover interfer��ncias na absor����o dos nutrientes. Assim, um experimento foi realizado, no ano agr��cola de 1991/92, num Latossolo Vermelho-Escuro argiloso no Centro Nacional de Pesquisa de Solos/Embrapa, em Senador Canedo (GO), com o objetivo de determinar os teores e as quantidades absorvidas de nitrog��nio, f��sforo e pot��ssio na parte a��rea da Crotalaria juncea: l., Crotalaria ochroleuca: G. Don, mucuna preta ( Mucuna aterrima (Piper & Tracy) Merr.) e guandu cv. Kaki (Cajanus cajan (L.) Millsp.), em tr��s ��pocas de semeadura (in��cio, meados e final da esta����o chuvosa) e em dois espa��amentos entrelinhas (0,5 e 0,4 m). O delineamento experimental, dentro de cada ��poca, foi o de blocos ao acaso em parcelas subdivididas, com tr��s repeti����es. As esp��cies diferiram entre si quanto aos teores e quantidades absorvidas de N, P e K. Ao contr��rio das ��pocas de semeadura, n��o houve efeito significativo dos espa��amentos nos teores e quantidades absorvidas de N, P e K. A intera����o de esp��cies e ��pocas de semeadura foi significativa apenas para o nitrog��nio e f��sforo.

Contribui����o dos mecanismos de fluxo de massa e de difus��o para o suprimento de K, Ca e Mg a plantas de arroz

O transporte de nutriente at�� �� superf��cie das ra��zes pode ocorrer por fluxo de massa ou por fluxo de massa e difus��o, dependendo da atividade do nutriente na solu����o do solo e da exig��ncia nutricional da planta. Objetivou-se verificar a contribui����o dos mecanismos de fluxo de massa e de difus��o para o suprimento de pot��ssio, de c��lcio e de magn��sio a plantas de arroz, em experimento realizado em casa de vegeta����o. Aplicaram-se em amostra de Latossolo Varia����o Una, os seguintes tratamentos: Na2CO3, K2CO3, CaCO3 e MgCO3. Aos 75 dias da semeadura, as plantas de arroz foram colhidas e determinadas as quantidades de pot��ssio, de c��lcio e de magn��sio nelas acumuladas, bem como a concentra����o desses nutrientes na solu����o do solo. Essas concentra����es, multiplicadas pelo volume de ��gua transpirado, foram usadas para calcular o suprimento por fluxo de massa. A difus��o foi estimada por diferen��a entre a quantidade do nutriente acumulado no vegetal e a transportada por fluxo de massa. Verificou-se que o pot��ssio foi transportado predominantemente por difus��o, exceto no tratamento com K2CO3, que gerou altos teores de K na solu����o de solo, tornando o fluxo de massa suficiente para atender �� demanda das plantas. O c��lcio e o magn��sio foram transportados por fluxo de massa. Segundo os resultados, a difus��o foi o principal mecanismo de transporte de pot��ssio nas condi����es do experimento; todavia, o fluxo de massa pode satisfazer isoladamente a demanda nutricional da planta, quando a concentra����o de pot��ssio na solu����o do solo for muito elevada.

The yield of high-density electric source imaging in focal epilepsy

Background: EEG is the cornerstone of epilepsy diagnostics and mandatory to determine the underlying epilepsy syndrome (e.g. focal vs idiopathic generalized). However, its potential as imaging tool is still underrecognized. In the present study, we aim to determine the prerequisites of maximal benefit of electric source imaging (ESI) to localize the irritative zone in patients with focal epilepsy. Methods: 150 patients suffering from focal epilepsy and with minimum 1 year post-operative follow-up were studied prospectively by reviewers blinded to the underlying diagnosis and outcome. We evaluated the influence of two important factors on sensitivity and specificity of ESI: the number of electrodes (low resolution, LR-ESI: \30 vs. high resolution, HR-ESI: 128-256 electrodes), and the use of individual MRI (i-MRI) vs. template MRI (t-MRI) as head model.Results: ESI had a sensitivity of 85% and a specificity of 87% when HR-ESI with i-MRI was used. Using LR-ESI, sensitivity decreased to 68%, or even 57% when only t-MRI was available. The sensitivity of HR-ESI/i-MRI compared favorably with those of MRI (76%), PET (69%) and ictal/interictal SPECT (64%).Interpretation: This study on a large patient group shows excellent sensitivity and specificity of ESI if 128 EEG channels or more are used for ESI and if the results are co-registered to the patient's individual MRI. Localization precision is as high as or even higher than established brain imaging techniques, providing excellent costeffectiveness in epilepsy evaluation. HR-ESI appears to be a valuable additional imaging tool, given that larger electrode arrays are easily and rapidly applied with modern EEG equipment and that structural MRI is nearly always available for these patients.

Incremental growth of the Patagonian Torres del Paine laccolith over 90 k.y.

The Miocene Paine Granite in the Torres del Paine Intrusive Complex, southern Chile, is an extraordinary example of an upper crustal mafic and granitic intrusion. The granite intruded as a series of three sheets, each one underplating the previous sheet along the top of the basal Paine Mafic Complex. High-precision U/Pb geochronology on single zircons using isotope dilution-thermal ionization mass spectrometry yields distinct ages of 12.59 +/- 0.02 Ma and 12.50 +/- 0.02 Ma, respectively, for the first and last sheet of the laccolith. This age relationship is consistent with field observations. The zircon ages define a time frame of 90 +/- 40 k.y. for the emplacement of a >2000-m-thick granite laccollith. These precise U-Pb zircon ages permit identification of the pulses in a 20 k.y. range. The data obtained for the Paine Granite fill the gap between 100 k.y. and 100-1000 yr pulses described in the literature for crustal magma chambers.

Prevention of vitamin K deficiency bleeding with three oral mixed micellar phylloquinone doses: results of a 6-year (2005-2011) surveillance in Switzerland.

In 2003, the Swiss guidelines to prevent vitamin K deficiency bleeding (VKDB) were adapted. As two oral doses (2 mg, hour/day 4) of mixed micellar VK preparation had failed to abolish late VKDB, a third dose (week 4) was introduced. This report summarizes the new guidelines acceptance by Swiss pediatricians and the results of a prospective 6-year surveillance to study their influence on the incidence of VKDB. The new guidelines acceptance by Swiss pediatricians was evaluated by a questionnaire sent to all pediatricians of the Swiss Society of Paediatrics. With the help of the Swiss Paediatric Surveillance Unit, the incidence of VKDB was monitored prospectively from July 1, 2005 until June 30, 2011. Over a 6-year period (458,184 live births), there was one case of early and four cases of late VKDB. Overall incidence was 1.09/10(5) (95 % confidence intervals (CI) 0.4-2.6). Late VKDB incidence was 0.87/10(5) (95 % CI 0.24-2.24). All four infants with late VKDB had an undiagnosed cholestasis at the time of bleeding; parents of 3/4 had refused VK prophylaxis, and in 1/4, the third VK dose had been forgotten. Compared with historical control who had received only two oral doses of mixed micellar VK (18 cases for 475,372 live births), the incidence of late VKDB was significantly lower with three oral doses (Chi(2),Yates correction, P = 0.007). CONCLUSION: VKDB prophylaxis with 3 �� 2 mg oral doses of mixed micellar VK seems to prevent adequately infants from VKDB. The main risk factors for VKDB in breast-fed infants are parental VK prophylaxis refusal or an unknown cholestasis.

M��todo convencional e "bootstrap" para estimar o n��mero de observa����es na determina����o dos par��metros da fun����o K(Θ)

A variabilidade natural do solo dificulta a obten����o de valores que representem adequadamente as propriedades do solo em determinada ��rea. O conhecimento do n��mero m��nimo de observa����es, que devem ser realizadas para representar, com um erro aceit��vel, uma propriedade ou caracter��stica do solo, �� fundamental para que os resultados experimentais possam ser aplicados com seguran��a. No presente trabalho, comparou-se o m��todo convencional (teste-t) com o m��todo "bootstrap", com vistas em estimar o n��mero de observa����es necess��rias para calcular os par��metros que caracterizam a rela����o entre a condutividade hidr��ulica e o teor de ��gua do solo, determinada pelo m��todo do perfil instant��neo. Realizou-se um experimento de drenagem num Latossolo Vermelho-Amarelo em Piracicaba (SP), numa parcela experimental com 45 pontos de observa����o distanciados de 1 m entre si. Observaram-se a umidade (com TDR) e o potencial m��trico (com tensi��metros) durante tr��s semanas de redistribui����o da ��gua. Ap��s processamento dos dados, o conjunto de valores mostrou uma distribui����o n��o-normal, fazendo-se necess��ria a elimina����o de "outliers" para a aplica����o do m��todo convencional, normalizando a distribui����o. Assim, o uso do m��todo tradicional s�� �� recomendado ap��s a confirma����o da pertin��ncia da elimina����o dos "outliers". Ambos os m��todos de an��lise requerem grande n��mero de repeti����es, reafirmando que determina����es da fun����o condutividade hidr��ulica com poucas repeti����es n��o podem ser extrapoladas para ��reas maiores.
