Quantitative evaluation of side-channel security for Elliptic Curve Cryptosystems

Side-channel security has aroused widespread attentions since the first publication of power analysis attack. Enormous research efforts were dedicated to new countermeasures against side-channel attacks. However, there have been very few reports about how to quantitatively verify the effectiveness. This paper presents statistical approaches of quantitative evaluation for Elliptic Curve Cryptosystems. The significance test over the difference of mean measures the distinguishability of the secret key in scalar multiplication. Experiment results demonstrate that the proposed evaluation approaches are accurate and feasible.
Determination of Chloramphenicol and Thiamphenicol Residues in Fish, Shrimp and Milk by ESI-LCMS/MS

Chloramphenicol (CAP) and thiamphenicol (TAP) – analogue of CAP are widely used in the growth of animals and marine culture as they are broad spectrum antibiotics. Due to the development of resistance of microorganisms against antibiotics many countries have completely banned the use of them. A Negative Electro spray ionization mode with liquid chromatography and mass spectrometry was used to monitor the contamination of TAP and CAP in shrimp, fish and milk. Transitions 321 → 152, 120.4, 257 for CAP, 326 → 126, 157, 262 for CAP IS and 354 → 184.9, 168.8, 78.8 for TAP were monitored. For extraction of antibiotics ethyl acetate was used, showed recovery batter than 75% in all three matrixes. For timely efficient separation Agilent Eclipse C18 column was used with the simple isocratic mobile phase methanol as A (99%) and water: methanol in ratio of (8:2) as a B (1%), which needed 3.5 min to elute out both the compounds. Full validation was done as per EU decision 2002/657. Linearity was greater than 0.99. Coefficient variation was performed at 3 different concentrations and it was not greater than 3% between 6 replicates. CCα and CCβ in different matrices on an average were 0.27 and 0.29 μg/kg for CAP and 51.85 and 53.45 μg/kg for TAP. Accuracy was calculated at three different concentrations and the readings were found between 90 to 110%. Youden approach was used for the calculation of ruggedness and their statistically calculated results were satisfactory. Method was applied to the samples in which 56 shrimp, 18 fish and 8 milk samples were tested and 4 shrimp samples were found positive at MRPL level V.R. Vora & M.K. Raikwar 824 so that the method is fit for CAP and TAP analysis of commercial products at MRL compliance.
Probabilistic Risk Assessment in Medium Scale for Rainfall-Induced Earthflows: Catakli Catchment Area (Cayeli, Rize, Turkey)

The aim of the present study is to introduce a probabilistic approach to determine the components of the risk evaluation for rainfall-induced earthflows in medium scale. The Catakli catchment area (Cayeli, Rize, Turkey) was selected as the application site of this study. The investigations were performed in four different stages: (i) evaluation of the conditioning factors, (ii) calculation of the probability of spatial occurrence, (iii) calculation of the probability of the temporal occurrence, and (iv) evaluation of the consequent risk. For the purpose, some basic concepts such as “Risk Cube”, “Risk Plane”, and “Risk Vector” were defined. Additionally, in order to assign the vulnerability to the terrain units being studied in medium scale, a new more robust and more objective equation was proposed. As a result, considering the concrete type of roads in the catchment area, the economic risks were estimated as 3.6×106€—in case the failures occur on the terrain units including element at risk, and 12.3×106€—in case the risks arise from surrounding terrain units. The risk assessments performed in medium scale considering the technique proposed in the present study will supply substantial economic contributions to the mitigation planning studies in the region.
Development and Validation of a Simplified Falls Assessment Tool in an Acute Care Setting

An easy-to-use assessment tool, which contains reversible risk factors, might influence the success of a falls prevention program. A 2-phase study was undertaken to develop and validate a simplified falls assessment tool. Risk factors of confusion, dizziness, altered elimination, and difficulty with mobility were found to be significantly associated with fall status. The simplified falls assessment tool that contains these 4 risk factors yielded a comparable predictive value to Hendrich II Falls Risk Model.
Digital Text Collections, Linguistic Research Data, and Mashups: Notes on the Legal Situation

Comprehensive data repositories are an essential part of practically all research carried out in the digital humanities nowadays. For example, library science, literary studies, and computational and corpus linguistics strongly depend on online archives that are highly sustainable and that contain not only digitized texts but also audio and video data as well as additional information such as metadata and arbitrary annotations. Current Web technologies, especially those that are related to what is commonly referred to as the Web 2.0, provide a number of novel functions such as multiuser editing or the inclusion of third-party content and applications that are also highly attractive for research applications in the areas mentioned above. Hand in hand with this development goes a high degree of legal uncertainty. The special nature of the data entails that, in quite a few cases, there are multiple holders of personal rights (mostly copyright) to different layers of data that often have different origins. This article discusses the legal problems of multiple authorships in private, commercial, and research environments. We also introduce significant differences between European and U.S. law with regard to the handling of this kind of data for scientific purposes.
Employing fuzzy logic in the diagnosis of a clinical case

Fuzzy logic is a logical calculus which operates with many truth values (while classical logic works with the two values of true and false). Since fuzzy logic considers the truth of scientific statements like something softened, it is fruitfully applied to the study of biological phenomena, biology is indeed considered the field of complexity, uncertainty and vagueness. In this paper fuzzy logic is successfully applied to the clinical diagnosis of a patient who suffers from different diseases bound by a complex causal chain. In this work it is presented a mathematical foundation of fuzzy logic (with connectives and inference rules) and then the application of fuzzy reasoning to the study of a clinical case. Probabilistic logic is widely considered the unique logical calculus useful in clinical diagnosis, thus the usefulness of fuzzy logic and its relation with probabilistic logic is here explored. The presentation of the case is supplied with all the features necessary to affect a clinical diagnosis: physical exam, anamnesis and tests.
Physician ownership of physical therapy services. Effects on charges, utilization, profits, and service characteristics.

OBJECTIVE To evaluate the effects of physician ownership of freestanding physical therapy and rehabilitation facilities on utilization, charges, profits, and three measures of service characteristics for physical therapy treatments. DESIGN Statistical comparison by physician joint venture ownership status of freestanding physical therapy and comprehensive rehabilitation facilities providing physical therapy treatments in Florida. PARTICIPANTS A total of 118 outpatient physical therapy facilities and 63 outpatient comprehensive rehabilitation facilities providing services in Florida during 1989. The data from the facilities were collected under a legislative mandate. MAIN OUTCOME MEASURES Visits per patient, average revenue per patient, percent operating income, percent markup, profits per patient, licensed therapist time per visit, and licensed and nonlicensed medical worker time per visit. RESULTS Visits per patient were 39% to 45% higher in joint venture facilities. Both gross and net revenue per patient were 30% to 40% higher in facilities owned by referring physicians. Percent operating income and percent markup were significantly higher in joint venture physical therapy and rehabilitation facilities. Licensed physical therapists and licensed therapist assistants employed in non-joint venture facilities spend about 60% more time per visit treating physical therapy patients than licensed therapists and licensed therapist assistants working in joint venture facilities. Joint ventures also generate more of their revenues from patients with well-paying insurance. CONCLUSION Our results indicate that utilization, charges per patient, and profits are higher when physical therapy and rehabilitation facilities are owned by referring physicians. With respect to service characteristics, joint venture firms employ proportionately fewer licensed therapists and licensed therapist assistants to perform physical therapy, so that licensed professionals employed in joint venture businesses spend significantly less time per visit treating patients. These results should be of interest to the medical profession, third-party payers, and policymakers, all of whom are concerned about the consequences of physician self-referral arrangements.
Platelet-rich fibrin as a scaffold in combination with either deciduous or permanent dental pulp cells for bone tissue engineering

Objective: To determine if Choukroun’s platelet-rich fibrin (PRF) can increase the osteogenic properties of deciduous and permanent dental pulp cells (DPCs), we evaluated the ability of PRF to stimulate the proliferation and differentiation of these DPCs. Methods: Primary cultured deciduous and permanent DPCs were obtained from 3-month-old and 16-month-old canines, respectively. Blood samples were obtained from the canines and centrifuged to extract PRF. The cell counts and cytotoxicity tests were performed at 1, 4, 7, and 11 days after culture. In addition, deciduous and permanent DPC were cultured under 4 different conditions: control group (without PRF in normal medium), test group (with PRF in normal medium), test group D (without PRF in differentiation medium) and test group D0 (with PRF in differentiation medium). Osteoblast differentiation was analysed using Alizarin Red staining and alkaline phosphatase (ALP) activity. Results: PRF did not have a toxic effect on the cells. It significantly increased the proliferation of both deciduous and permanent DPCs, reaching levels up to 2.5, 3.0, 2.0 and 2.8 times compared to those of controls at 7 and 11 days after inoculation, respectively (P < 0.01). In addition, PRF significantly stimulated differentiation of all DPCs as shown by increased calcium nodules (P < 0.05), up-regulated ALP levels, and elevated expression of osteogenesis-related genes (P < 0.05). These effects were more pronounced in deciduous cells than in permanent cells. Conclusions: PRF has an obvious stimulatory effect on the proliferation and differentiation of both deciduous and permanent DPCs in vitro, suggesting that PRF promotes osteogenesis. Therefore, the combination of PRF with both either deciduous or permanent DPCs could be a promising method for bone tissue engineering.
Biological Control of the Invasive Dryocosmus kuriphilus (Hymenoptera: Cynipidae) - an Overview and the First Trials in Croatia

Background and Purpose: Dryocosmus kuriphilus is a globally invasive insect pest, spreading very quickly in new habitats and making serious damage to sweet chestnut forests in Croatia and in several other European countries. Indigenous parasitoid species trophically associated with oak gallwasps have adapted to this new host but cannot effectively regulate its population density. Classical biological control using parasitoid Torymus sinensis has been proven to be the only effective method of controlling the populations of D. kuriphilus and has been successfully applied in Japan, South Korea, the USA and Italy. The aim of this review paper is to provide overview and up-to date knowledge about biological control of D. kurphilus and to describe first steps of introduction of T. sinensis to sweet chestnut forests in Croatia. Conclusions and Future Prospects: Results presented in this paper show adapted biology and behavioural traits of T. sinensis to its host D. kuriphilus. The history and results of introductions of T. sinensis to Japan, the USA, Italy, France and Hungary are shown. The first report of release of T. sinensis to sweet chestnut forests in Croatia is given with discussion on native parasitoids attacking D. kuriphilus. Possible negative effects of T. sinensis on native parasitoid fauna and risks that could influence the successful establishment of T. sinensis in Croatia are discussed. Previous experiences have shown that T. sinensis can successfully control the population density of D. kuriphilus, slowing down the spread and mitigating negative impact of this invasive chestnut pest and keeping the damage of D. kuriphilus at acceptable level. High specificity of T. sinensis suggests that it has limited potential of exploiting native hosts but further detailed monitoring of native parasitoid and possible interactions with introduced T. sinensis is strongly suggested.
Insulin resistance in patients with polycystic ovary syndrome is associated with elevated plasma homocysteine.

BACKGROUND Elevated levels of plasma homocysteine have recently been implicated as a significant risk factor for cardiovascular disease, pre-eclampsia, and recurrent pregnancy loss, and have been found to be associated with insulin resistance in a number of clinical situations. We examined the relationship between plasma homocysteine and insulin resistance in patients with polycystic ovary syndrome (PCOS). METHODS A total of 155 infertile patients with PCOS as defined by clinical, biochemical and ultrasound criteria were screened for insulin resistance utilizing single-sample fasting insulin and glucose measurement, calculated by glucose:insulin ratio or homeostasis model assessment (HOMA) index. Total plasma homocysteine was measured by fluorescence polarization immunoassay. One hundred normo-ovulatory women with normal ovaries being treated for other infertility diagnoses served as a control group. RESULTS Insulin resistance was found in the majority of PCOS patients: -53.5% (83/155), 60.6% (94/155) and 65.8% (102/155), when defined by fasting insulin, glucose:insulin ratio, or logHOMA respectively. Mean plasma homocysteine in the PCOS group was significantly higher than in the normal ovary group (11.5 +/- 7.4 versus 7.4 +/- 2.1 micromol/l, P < 0.001). Insulin-resistant PCOS patients had significantly higher plasma homocysteine (12.4 +/- 8.4 micromol/l) than non-insulin-resistant PCOS patients (9.6 +/- 4.4 micromol/l) regardless of body mass index (P = 0.003 by groups, P = 0.005 by correlation of single samples). Thirty-four per cent (53/155) of the PCO patients had homocysteine values >95th percentile of the controls (11.0 micromol/l, P < 0.0001). Statistically significant correlations were found between all insulin resistance indices and homocysteine levels. Multiple logistic regression defined insulin resistance as the major factor examined that influenced homocysteine levels. CONCLUSIONS Insulin resistance and hyperinsulinaemia in patients with PCOS is associated with elevated plasma homocysteine, regardless of body weight. This finding may have important implications in the short term regarding reproductive performance, and in the long term regarding cardiovascular complications associated with insulin-resistant PCOS.

Morphological and biochemical basis of centchroman as a novel antineoplastic agent in MCF-7 human breast cancer cells

OBJECTIVE: To investigate the antineoplastic potential of a novel antiestrogen (AE) centchroman (CENT) using cell morphology, viability and cathepsin-D (Cath-D) gene expression as indices in MCF-7 human breast cancer cell line. MATERIAL AND METHODS: MCF-7 cells were incubated with CENT (1 µM, 10 µM) in the absence and presence of 17- estradiol (E2, 10 nM) for 4 days. Investigations were carried out on alterations in cell morphology, number, Cath-D gene expression using Phase Contrast Microscopy, Trypan-blue dye exclusion and spectrophotometric assay. A standard antiestrogen and antibreast cancer agent tamoxifen (TAM -1 µM, 10 µM) was used as a positive control. RESULTS: E2 (10 nM) alone significantly up-regulated the cells morphologically, numerically and biochemically thus establishing their hormonal responsiveness. TAM and CENT at 1 µM each enhanced and reduced the viable cell number respectively whereas both elevated the Cath-D activity. However, 35mm photographic evidence did not indicate any cytotoxic effect with either drug as compared to control. Addition of E2 to the two ligands separately affected the three parameters similar to that in E2 alone. With 10 µM TAM and CENT individually, the cells were visually devastated and so were the viable cell numbers and Cath-D gene expression. Supplementation of E2 under similar conditions failed to undo the damage to the cells morphologically and quantitatively. However, disparate results were observed with regards to the enzyme activity where TAM+E2 caused inhibition and CENT+E2 resulted in an induction. CONCLUSION: It can be concluded that both the AEs TAM and CENT displayed similarities in their antineoplastic action on MCF-7 cells as observed by morphological and viability studies except that the latter proved cytotoxic even at 1µM concentration. TAM and CENT showed a similar effect on Cath-D gene expression except at the higher dose (10 µM). These results suggest that the antiestrogen CENT has better antineoplastic potential as opposed to TAM.
A‐type K+ current dominates somatic excitability of delayed firing neurons in rat substantia gelatinosa

Substantia gelatinosa neurons display three main types of intrinsic firing behavior: tonic, adapting, and delayed onset. Here, voltage‐gated currents expressed by delayed firing neurons were studied in nucleated patches obtained in spinal cord slices of 3–5 weeks‐old rats. Inward Na+ current was negligible under these conditions and was usually occluded by superposition of much larger outward currents. Two kinds of outward currents were found, an A‐type (KA) and delayed rectifier (KDR) potassium currents. KA activated rapidly (<1.5 ms at >−20 mV) and operated at subthreshold membrane potentials; voltages of steady‐state half‐maximal activation and inactivation were −38.7 and −87.2 mV, respectively. Inactivation was biexponential with a dominant fast component (∼90%, time constant ∼8 ms). KDR activated more slowly (<8 ms at >−20 mV), half‐maximal activation was −23.6 mV, and decayed mono‐exponentially with a time constant 70–110 ms. Maximal amplitudes of KA were almost 10‐times larger than those of KDR, their respective densities were 8.5 and 0.97 μS μm−2. Tetraethylammonium, 5 mM, blocked KDR but not KA, whereas both currents were depressed by 5 mM 4‐aminopyridine. In current‐clamp recordings, 4‐action potential but not tetraethylammonium abolished firing delay suggesting the causative role of KA. Thus, the predominance of fast KA over other somatic currents is a distinctive feature of delayed firing neurons among all other types of substantia gelatinosa neurons and likely explains the appearance of their typical firing delay.

A Detachable Electronic Device for Use With a Long White Cane to Assist With Mobility

Vision-impaired individuals often use a long white cane to assist them with gathering information about their surroundings. However, these aids are generally not used to detect obstacles above knee height. The purpose of this study is to determine whether a low-cost, custom-built electronic device clipped onto a traditional cane can provide adequate vibratory warning to the user of obstacles above knee height. Sixteen normally sighted blindfolded individuals participated in two mobility courses which they navigated using a normal white cane and a white cane with the electronic device attached. Of the 16 participants, 10 hit fewer obstacles, and 12 covered less ground with the cane when the electronic device was attached. Ten participants found navigating with the electronic device easier than just the white cane alone. However, the time taken on the mobility courses, the number of collisions with obstacles, and the area covered by participants using the electronic device were not significantly different (p > 0.05). A larger sample size is required to determine if the trends found have real significance. It is anticipated that additional information provided by this electronic device about the surroundings would allow users to move more confidently within their environment.
Some Results from an Empirical Study of Computer Software

A study has been carried out to relate the maintenance performance of a collection of PL/I programs to measures that characterize control flow, data usage, and software science attributes of the programs. The programs are from two subsystems of a business data processing application. Interesting relationships were found not only between the maintenance data and the measures but also among the measures themselves. This paper discusses some of the stronger of these relationships.
