Improving penetration testing through static and dynamic analysis (2011)

Abstract Penetration testing is widely used to help ensure the security of web applications. Using penetration testing, testers discover vulnerabilities by simulating attacks on a target web application. To do this efficiently, testers rely on automated techniques that gather input vector information about the target web application and analyze the application's responses to determine whether an attack was successful. Techniques for performing these steps are often incomplete, which can leave parts of the web application untested and vulnerabilities undiscovered. This paper proposes a new approach to penetration testing that addresses the limitations of current techniques. The approach incorporates two recently developed analysis techniques to improve input vector identification and detect when attacks have been successful against a web application. This paper compares the proposed approach against two popular penetration testing tools for a suite of web applications with known and unknown vulnerabilities. The evaluation results show that the proposed approach performs a more thorough penetration testing and leads to the discovery of more vulnerabilities than both the tools.

New Procedures and Materials for Improving Protection of Archaeological Areas (2011)

The paper explains the role of nondestruvtive testing (NDT) in the protecion of archaeologicals sites, as well as research activity and a pilot ptoject in Sardinia, an island region of Italy. Microclimate, surface temperature and sun irradiation, as well as wind direction and speed, were monitored for two years by means of infrared thermography, psychrometry and probes to determine the requirements for a new shelter. In addition, several technical aspects were analysed, highlighting how covering solutions can often contribute to damage instead of offering protection.
THE PLASTIC DEFORMATION OF SINGLE CRYSTALS OF ALUMINUM SUMMARY REPORT (1952)

Most research into the validity of graduate medical education in-training examinations has focused on construct validity and concurrent validity issues. This study examined the predictive validity of the American Board of Family Practice In-Training Examination using multivariate analysis of all U.S. family practice residents who took the certification examination in either 1987 or 1988. Results of these two certification examinations were analyzed for the cohorts of physicians who had taken in-training examinations as first-, second-, and third-year residents. Multiple regression analysis showed that the composite score, and all but one part-score, of each in-training examination were independently predictive of performance on the certification examination. This study also found that the older residents did less well on the certification exam, and that men and women each did better on selected portions of the examination. The implications of these findings for in-training examinations in other specialties and for program directors and residents are discussed.

The Lomakin Effect in Annular Gas Seals Under Choked Flow Conditions (2006)

The paper deals with the static stability of annular gas seals under choked flow conditions. For a centered straight annular seal choking can occur only in the exit section because the gas is constantly accelerated by friction forces. From the mathematical standpoint, the flow choking corresponds to a singularity that was never dealt with numerically. The present work introduces an original numerical treatment of this singularity that is validated by comparisons with the analytical solution for planar channel flow. An interesting observation stemming from these results is that the usual hypothesis of considering the flow as being isothermal is not correct anymore for a gas accelerated by a pressure gradient; the characteristics of the flow are the same but the quantitative results are different. The analysis of eccentric annular seals then shows that choked flow conditions produce a change in the static stiffness. For a subsonic exit section the Lomakin effect is represented by a centering radial force opposed to the rotor displacement. For a choked exit section the radial force stemming from an eccentricity perturbation has the same direction as the rotor displacement. The annular seal becomes then statically unstable. From the physical standpoint this behaviour is explained by the modification of the Lomakin effect that changes sign. The pressure and Mach number variations along the seal depict the influence of high compressible flow regimes on the Lomakin effect. This characteristic has never been depicted before.

Spatial patterns of protein expression in focal infections of human cytomegalovirus (2006)

Human cytomegalovirus (HCMV) is a medically significant human pathogen that infects a wide range of cell and tissue types. During infection, HCMV activates a variety of signal transduction pathways that induce profound changes in cellular processes and dramatically affect cellular gene expression patterns. To better define how these virus-host interactions affect the local microenvironment and influence the spatial and temporal spread of HCMV, we initiated HCMV focal infections on normal human dermal fibroblast monolayers and monitored viral gene expression patterns and infection spread over 45 days. To establish baseline temporal measurements of HCMV infection and spread in cell monolayers, we characterized the influence of three experimental variables on viral gene expression: cell plating density, the presence of serum, and neutralization of cellular antiviral responses with an antibody against interferon-beta. We found that high cell plating density or the inclusion of serum correlated with enhanced HCMV infection spread. Dramatic differences in the expression pattern of the viral immediate early 2 (IE2) gene were observed under these conditions as compared to low plating density or the absence of serum. In the latter case round, uniform foci were observed with a clear wave of IE2 expression visible in advance of a late stage viral protein, envelope glycoprotein B. By contrast, larger irregular foci with arms of IE2 expression were observed in the presence of serum. Addition of the antibody had little effect on the rate of spread, which is consistent with the knowledge that HCMV represses antiviral responses during infection. This experimental system provides a useful means to visualize and quantify complex virus-host interactions.
Integrated corner mirrors physically micromachined in silica-on-silica (2011)

In integrated photonics, compact redirection of light can be achieved by corner (turning) mirrors, providing a route to higher density optical components. Corner mirrors have been demonstrated in both silicon-on-insulator and hollow waveguides with reported losses of 0.9dB [1] and 0.8dB [2] respectively. We report a novel method of fabricating mirrors on a silica-on-silicon substrate. The method utilises the complementary techniques of physical micromachining and direct UV writing, both providing rapid prototyping outside the cleanroom environment.
Urodynamic changes in a noble rat model for nonbacterial prostatic inflammation (2007)

Elevated estrogen concentration was essential for the gradual development of prostatic inflammation. The profile and location of inflammatory cells suggest that prostatic vasculature is one of the sites of estrogen action. Urodynamic changes which developed in association with glandular inflammation indicated abnormal bladder function, reflecting an incipient obstruction.
Outcomes in Mantle Cell Lymphoma for Elderly Patients Undergoing Autologous Stem Cell Transplant in CR1 (2017)

Introduction: Consolidation with autologous stem cell transplant (ASCT) in first complete remission (CR) is often utilized for fit patients with newly diagnosed mantle cell lymphoma (MCL) and is generally safe with low rates of transplant related mortality. However, elderly patients are often excluded from ASCT due to safety concerns. We evaluated outcomes for elderly patients with MCL in a multi-center cohort. Methods: We retrospectively evaluated MCL patients from 5 centers, including patients >65 years old with available treatment and survival data. In patients between 66 and 75 years of age, we compared those who did and did not receive ASCT in first CR based on demographic, clinical, and treatment-related variables of interest using chi-squared tests and ANOVA. We evaluated the impact of ASCT on outcomes including progression-free (PFS) and overall survival (OS) using Cox Proportional Hazards models and Kaplan-Meier curves. We also described the rate of non-relapse mortality (NRM) using competing risks and cumulative incidence curves, where progression prior to death was considered a competing event. Time to event was calculated from the date of diagnosis, with non-relapsing, alive patients censored at the time of last follow-up. Results: Of 94 patients 66-75 years old, 29 completed ASCT in first remission and 65 patients did not. Median age was 67 years in the ASCT patients and 70 years in the non-ASCT patients (P = .02). MIPI score was low-risk in 0%, intermediate-risk in 77%, and high-risk in 23% for ASCT patients versus 13%, 42%, and 44% for non-ASCT patients (P = .07). Ki-67 > 30% was 55% versus 42% (P = .47), Stage III or IV disease was 96% versus 94% (P = .53), and ECOG PS > 1 was 5% versus 9% (P = .46) for ASCT versus non-ASCT patients, respectively. Non-relapse mortality (NRM) at 1, 2, and 5 years was 0%, 0%, and 6.0% in the ASCT group versus 1.6%, 3.4%, and 8.6% in the non-ASCT group respectively (HR = .51; P = .53). The median PFS was 4.4 years (95%CI, 3.5-not reached) in ASCT patients and 2.9 years (95%CI, 2.3 Ð 5.2) in non-ASCT patients (HR .65, P = .19). Median OS (Figure 1) was not reached in the group that underwent ASCT and was 13.2 yrs in the group that did not undergo ASCT (Figure 1; HR .52, P = .24). 2-year overall survival (OS) was 100% in pts who underwent ASCT versus 89% (95%CI, 77%-95%) in non-ASCT pts. 5-year OS was 88% (59%-97%) and 64%(45%-78%) in the ASCT and non-ASCT groups respectively. Conclusion: In elderly MCL patients, ASCT is not associated with increased NRM and should be considered a safe therapy approach in eligible patients. Although there is not a clear benefit in median OS, there is a trend towards improved 2 year-OS and 5 year-OS in the ASCT group. Additional studies using larger databases are needed to further evaluate these findings; as well to prospectively identify the patients most likely to benefit from an intensive, ASCT-containing approach versus those who can potentially receive less aggressive therapy.

Enhancement of Push–Pull Properties of Pentafulvene and Pentafulvalene Derivatives by Protonation at Carbon (2018)

We report visible color changes and new intense, bathochromically shifted bands in electronic absorption spectra that reach into the near‐infrared region (up to 862 nm) upon protonation of nine pentafulvene and expanded pentafulvalene derivatives. This phenomenon can only be explained by the formation of carbocations with highly delocalized charges. Solution p K a values in organic solvents were determined, making use of the method of relative basicity measurements. All seven 6‐phenylpentafulvenes are weak bases, and p K a values of the protonated forms range from 0.92 to 10.29 in acetonitrile and from 1.3 to 5.9 in 1,2‐dichloroethane. For 6‐phenylfulvenes with varying para ‐substituents on the phenyl ring, p K a values correlate well with the Hammett parameters σ para . Furthermore, for most compounds, electrochemical reduction is significantly facilitated by protonation. Extensive theoretical and NMR studies strongly support the postulated protonation at carbon.
Progesterone, but Not Medroxyprogesterone, Inhibits Vascular Cell Adhesion Molecule-1 Expression in Human Vascular Endothelial Cells (2001)

-It has been shown that ovarian steroid hormones can reduce the incidence of cardiovascular disease in postmenopausal women. As hormone replacement therapy for postmenopausal women, progestins are added to estrogens to eliminate the increased risk of endometrial cancer. However, the effects of progestins on the atherogenic process have not been well understood. In the present study, we examined the effects of progestins on the expression of vascular cell adhesion molecule-1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs). Immunocytochemical analysis revealed the presence of progesterone receptors in HUVECs. Progesterone clearly inhibited tumor necrosis factor-alpha-activated expression of VCAM-1 protein and its mRNA in HUVECs. Synthetic progesterone receptor agonist R5020 also inhibited the tumor necrosis factor-alpha-activated VCAM-1 expression, whereas medroxyprogesterone acetate (MPA) failed to do so. Electrophoretic mobility shift assays demonstrated that progesterone, but not MPA, inhibited DNA binding of the transcription nuclear factor-kappaB, which is critical for the inducible expression of VCAM-1. Because the expression of VCAM-1 is one of the earliest events that occurs in the atherogenic process, this adhesion molecule might be a target molecule for progesterone on vascular walls. The contrasting effects of progesterone and MPA seem clinically important, inasmuch as MPA is a widely used progestin in the regimen of hormone replacement therapy.

Magnetoestratigrafia de sedimentos cenozoicos en el oeste del gran Buenos Aires (2005)

Magnetostratigraphy of Cenozoic sediments in western Buenos Aires. A palaeomagnetic study of Quaternary sediments in western Buenos Aires city, was carried out in order to know their age and the time span during which the different processes of deposition and evolution took place. This study carried out on two profiles called CAS and GAO, recognized the upper 8m of the loessic plain sediments as belonging to the Brunhes Magnetic Polarity Zone (younger than 0.78 Ma), and the underlying sediments to the Matuyama Magnetic Polarity Zone. This significant extension in time supports geochemical and mineralogical studies that suggest the existence of different areas of origin of the sediments in the Pampa Ondulada, and modifies the traditional concept of their homogeneity. The change of magnetic polarity was found above a buried soil, at 13,30 m a.s.l., probably equivalent to the Hisisa Geosol, identified in other areas of the province as a regional palaeosurface and proposed as the upper boundary of the Matuyama Magnetic Polarity Zone. Taking into account the morphological features of the studied materials and the fact that this magnetic polarity boundary has been repeatedly found in the upper section of the Ensenada Formation, it is possible to correlate the sediments from the lower section of the CAS profile with this formation, whereas sediments of the upper level, as well as the ones recognized in the GAO profile, correlate with the Buenos Aires Formation.
Characterization of the chromosomes of Bacillus subtilis merodiploid strains by quantitative DNA-DNA hybridization (1994)

The position of junctions and the extent of the duplicated chromosomal regions in Bacillus subtilis merodiploid strains were studied by quantitative DNA-DNA hybridization. We describe a method which allows (i) the identification of genes present in two copies per chromosome and (ii) the measurement of the amount of additional DNA in chromosomes with relatively large duplicated regions (about 10% or more). Analysis of previously described B. subtilis merodiploid strains GSY1127, GSY1800 and GSY1835 revealed that the duplicated segments represent 29 +/- 2%, 7 +/- 2% and 13 +/- 2% of the chromosome, respectively. Small discrepancies between these and previous genetic linkage data are discussed. Support for a role of prophage SP beta in the formation of merodiploid GSY1835 is provided. In conclusion, the described method confirmed the genetic maps of the merodiploids previously obtained by transduction and transformation crosses and showed that a duplication of a segment is not accompanied by large deletions of other chromosomal regions, providing direct evidence that a cell can accommodate genomes of substantially increased size.
Pharmacologic Aspects of Synthetic Angiotonin (1957)

The synthetic octapeptide angiotonin evoked systolic and diastolic pressure responses in anesthetized and unanesthetized dogs identical with those due to a natural, largely decapeptide, angiotonin, and responses to both angiotonins were modified in the same manner by a variety of procedures. Infusion of synthetic angiotonin caused hypertension sustained for the durations of the infusions and tachyphylaxis was not observed. Induced tachyphylaxis to a crude renin preparation was accompanied by loss of response to both synthetic and natural angiotonin but not to norepinephrine.

Distribution of blood group antigens and CA 19-9 in gastric cancers and non-neoplastic gastric mucosa. (1984)

The distribution of blood group ABH antigens, their precursor I(Ma) antigen, Lewis a antigen and monoclonal antibody-defined tumor-associated antigen CA 19-9 in gastric cancers and their surrounding non-neoplastic mucosa was studied by using immunohistochemical methods. ABH antigens were localized in the foveolar epithelium except for a few cases presumed to be non-secretors, but ABH antigens were lost focally from metaplastic mucosa. In contrast, Lewis a and I(Ma) antigens were present in the foveolar epithelium of non-secretors and metaplastic mucosa where ABH antigens were not detected. Gastric cancers also showed focal loss of ABH antigens and gain of Lewis a and I(Ma) antigens, and the cancer cells showed marked heterogeneity in antigen expression compared with non-neoplastic mucosa. Expression of incompatible blood group antigen (A-like antigen) reactive with monoclonal anti-A antibody was also detected in cancer cells of blood group O and B cases. CA 19-9 (sialylated-Lewis a) was detected in 62% of gastric cancers and in the restricted areas of gastric mucosa where Lewis a was positive.
A Novel Method to Study the Effect of Corona Treatment on Ink Wetting and Sorption Behavior (2014)

A novel absorption test method was developed based on a modification of the Bristow Absorption Apparatus. The proposed method combines corona treatment (CT) with short contact time absorption behavior to study particularly ink wetting and sorption on substrates in-line. The method makes it possible to study e.g. the coagulation of pigment inks induced by deposited charges i.e. electrocoagulation, the effect of short contact times on liquid/substrate interactions, and problems related to charge decay such as whiskering. In-line measurement with a short delay time minimizes the effect of ambient conditions (heat, moisture) on charge decay, and thus simulates the conditions in commercial digital printing processes.The functionality of the method was evaluated by testing paper samples with and without polymer coatings. Uncoated samples were used to study absorption properties. It was found that in some cases the CT changes both the wetting and absorption of ink and that in other cases the main changes are in the absorption behavior. Four CT levels (0, −100, −450, and −900 W*min/m2) were studied and it was found that the highest treatment level increased the absorption of the applied inkjet ink the most. As expected, the contact time between liquid and substrate was found to be an important variable affecting the absorption. Print density and mottle were determined on coated samples with the CT levels of 0, −160, and +160 W*min/m2. CT improved print density significantly, whether the treatment was positive or negative, and also reduced the mottling tendency.
