Current Injection Attack against the KLJN Secure Key Exchange

The Kirchhoff-law-Johnson-noise (KLJN) scheme is a statistical/physical secure key exchange system based on the laws of classical statistical physics to provide unconditional security. We used the LTSPICE industrial cable and circuit simulator to emulate one of the major active (invasive) attacks, the current injection attack, against the ideal and a practical KLJN system, respectively. We show that two security enhancement techniques, namely, the instantaneous voltage/current comparison method, and a simple privacy amplification scheme, independently and effectively eliminate the information leak and successfully preserve the system's unconditional security

Urogenital tuberculosis — epidemiology, pathogenesis and clinical features

Tuberculosis (TB) is the most common cause of death from infectious disease worldwide. A substantial proportion of patients presenting with extrapulmonary TB have urogenital TB (UG-TB), which can easily be overlooked owing to non-specific symptoms, chronic and cryptic protean clinical manifestations, and lack of clinician awareness of the possibility of TB. Delay in diagnosis results in disease progression, irreversible tissue and organ damage and chronic renal failure. UG-TB can manifest with acute or chronic inflammation of the urinary or genital tract, abdominal pain, abdominal mass, obstructive uropathy, infertility, menstrual irregularities and abnormal renal function tests. Advanced UG-TB can cause renal scarring, distortion of renal calyces and pelvic, ureteric strictures, stenosis, urinary outflow tract obstruction, hydroureter, hydronephrosis, renal failure and reduced bladder capacity. The specific diagnosis of UG-TB is achieved by culturing Mycobacterium tuberculosis from an appropriate clinical sample or by DNA identification. Imaging can aid in localizing site, extent and effect of the disease, obtaining tissue samples for diagnosis, planning medical or surgical management, and monitoring response to treatment. Drug-sensitive TB requires 6–9 months of WHO-recommended standard treatment regimens. Drug-resistant TB requires 12–24 months of therapy with toxic drugs with close monitoring. Surgical intervention as an adjunct to medical drug treatment is required in certain circumstances. Current challenges in UG-TB management include making an early diagnosis, raising clinical awareness, developing rapid and sensitive TB diagnostics tests, and improving treatment outcomes

Survey on Mining Effective Information Using Ontology Based semantic web Crawler Mechanism

Due to usable of copious data on web, searching has a consequential impact. Ongoing study place emphasis on the relevancy and robustness of the data found, as the invent patterns proximity is far from the probe. In spite of their relevance pages for some investigate topic, the results are mammoth that needed and are explored. Also the users’ perspective differs in timely manner from topic to topic. In general terms ones’ want is others unnecessary. Crawling algorithms play crucial role in selecting the pages that satisfies the users’ needs. This paper reviews the research work on web crawling algorithms used on searching

Assessment the Pb, Cu and Cd Deposition at Southern Bypass Roadside Soil in Damascus-Syria

Contamination of heavy metals represents one of the most pressing threats to water and soil resources as well as human health, and the Assessment the Pb, Cu and Cd deposition was studied by analyzing soil samples, where have been collected from one site located near the Damascus Homs highway in Damascus-Syria (Southern Bypass road), Sampling plots were marked in each area at 5, 10,15,20,25,30,35,40,45 , 50 and 100 meters distance from the road, Three soil samples were taken from each distance in all selected sites, and all samples were analyzed first for soil texture, organic matter and pH then the samples have been digested and analyzed by atomic absorption spectrophotometer for total metal concentrations. The results indicated that soils of study area were clay loamy and it was basic in nature. Where total soil Pb, Cu, and Cd concentrations varied from 62.56, 13.55 and 2.11 To 0.021, 0.12 and 0.00 mg kg−1 respectively. The highest heavy metals concentration was found at a distance of 5 meters from the road, and contents of metals tended to decrease with increasing distance from the highway, where the lowest concentration at 100 meter. The results showed that the soil near the highway had significant enrichment, particularly in Pb, and to a lesser extent with Cu and Cd. Dependence on the obtained results of heavy metals, the more we move away from the side of road, the fewer ratios of heavy metals will be obtained, and therefore safer distance for growing crops

The use of intra aortic baloon pump in patients undergoing coronary artery bypass grafting at the Aga Khan University Hospital, Karachi

Objective: To review the experience in the use of Intra Aortic Balloon Pump (IABP) in patietits undergoing Coronary Artery Bypass Grafting (CABG) at a tertiary care hospital with a new Open Heart surgery program. Design: Retrospective study. Setting: The Aga Khan University Hospital, Karachi. Patients: Medical records of all patients undergoing CABG between November 1994 and July 1997 were reviewed and those in whom IABP device was used, were included in this study. Results: A total of 15 patients had IABP suppOrt during the study period. Four surgeries were done urgently while two were emergencies. There were three mortalities. Ejection fractions in all hut one patient were impaired. Among the surviving patients, the average pre-IABP Cardiac Index was 2.6 litres/mm/meter2 which registered an average increase of 21.15% after the initiation of the IABP. The Pulmonary Artery Wedge Pressure also showed an average reduction of 29.11% from the pre IABP levels reflecting an increase in the cardiac output with the use of the IABP. Conclusion: This series represents the early experience of a new cardiac surgery center in Pakistan in the use of IABP. Although the numbers in this study are too small to derive any conclusions, the overall morbidity and mortality in this short series are within acceptable limits in the high risk patients include

RESPIRATORY SYNDROME: A MAJOR THREAT TO THE LIVESTOCK FARMERS AND ITS ECONOMIC IMPACT

Epidemiology of a respiratory syndrome was studied at Landhi Dairy Colony (LDC), Karachi, Pakistan and its economic impact was estimated. Among 5889 buffaloes examined, 2.3% animals were suffering from this syndrome. From some of the sick animals, Pasteurella multocida, the causative agent of haemorrhagic septicaemia, was isolated. In the present study, an average loss of Rs. 0.2 million per farm was calculated and the extrapolated values for 0.2 and 0.8 million animals present in LDC and other dairy colonies in Karachi were Rs. 225.6 and Rs. 1128.1 million, respectively

Monthly average daily global and diffuse solar radiation based on sunshine duration and clearness index for Brasov, Romania

The main objective of this study is to develop single location appropriate models for the estimation of the monthly average daily global and diffuse horizontal solar radiation for Brasov, Romania. The study focuses particularly on models based on the sunshine duration and clearness index. The data used for the calibration of the models were collected during a period of 4 yr, between November 2008 and October 2012, at the Transilvania University of Brasov. The testing and validation of the models was carried out using data from the online SoDa database for Brasov for the year 2005. Different statistical error tests were applied to evaluate the accuracy of the models. The predicted values are also compared with values from three other known models concerning the global and diffuse solar radiation. A new mixed model was developed for the estimation of monthly average daily global horizontal solar radiation. The data processing was performed by means of a real-time interface developed with LabVIEW graphical programming language. The parameters taken into account were the relative sunshine, the clearness index, the extraterrestrial radiation, the latitude and the longitude. The methodology is simple and effective and may be applied for any region. Its effectiveness was proven through comparison with global models
