Security policy rules optimization and its application to the Iptables firewall (2011)

Abstract\n\nThe security of a network which is being connected to the Internet is of the highest importance especially if this network belongs to a private company or a bank. Many different methods have been invented and are currently used in order to prevent harm that can be caused by perpetrators to the local network. One of the most commonly used methods is a firewall. \n\nThe important feature of the firewall is the efficiency of its filtering. Since each packet is compared against filtering rules in the firewall, the firewall introduces a delay. The less the delay, the more efficient is the filtering.\n\nIn order to make network more secure, we have to make sure that firewall implements a given security policy and makes it efficiently. The ruleset should be examined for the presence of errors such as duplicated, shadowed and conflicting rules and those errors should be eliminated if found. Rules should be also rearranged to make filtering optimally efficient. Rule rearrangement could accidentally cause a change in the security policy and we have to make sure that it will not happen. \n\nWe study two different optimization approaches that can be applied to the ruleset of the firewall. The optimization approach that examines the ruleset and eliminates the errors is called static optimization since it uses a given ruleset and does not need any additional data. Another optimization approach that rearranges the rules' order in the ruleset is called dynamic optimization since it uses dynamic statistical information of the traffic which flows through the firewall.\n\nIn this work we consider different existing optimization approaches, both static as well as dynamic, and suggest a combination of their best features and improvements. We make sure that the suggested optimizations will not change the security policy of the initial ruleset at any time. We also consider peculiarities of the Iptables firewall and show how the suggested method can be applied to its ruleset.\n\n
Virtual Web Services (2010)

Several open issues in Web services architecture are being solved by using different kinds of solutions. Standard high-availability techniques based on the use of Web servers, business-logic-based caching systems, dynamic binding of Web services by programming the access to a SOAP message content from the business logic layer, and other kinds of current open problems can now be handled using a common unique technique. What we propose is to apply virtualization techniques to Web services.
Characterization of photoconductive CdS thin films prepared on glass substrates for photoconductive-sensor applications (2008)

Cadmium sulfide (CdS) thin films with n-type semiconductor characteristics were prepared at room temperature on glass substrates by radio-frequency magnetron sputtering for photoconductive-sensor applications. Films deposited at room temperature exhibit polycrystalline phases and show smooth surface morphologies. The deposition rate of the films decreases with increasing working pressure. The dark- and photoresistances in 400-nm-thick CdS films deposited at 6.7×10−1Pa and 80W were approximately 1×105 and 3×104Ω∕sq, respectively. Lowering both the dark- and photoresistances lowers the sensitivity (Rdark∕Rphoto) of the resistance.
Embedded magnetic power transformer (2013)

Inductors and transformers are basic building blocks in power systems. Their attributes are critical to the function and performance of a switch mode power converter (SMPC). Embedded magnetics provides a new approach for fabricating transformers and inductors. A key benefit of this approach is that it provides a practical means for employing toroid (ring) cores in power designs. Essentially, the fabrication is done with a Printed Circuit Board (PCB) line. Ferrite elements are embedded into an FR4 substrate and the device windings are realized using printed circuit techniques. Rather than fabrication one-at-a time, devices are fabricated in a batch format. Automation also brings the benefit of improved consistency and reliability. This paper describes the device composition and fabrication on a printed circuit line.
Numerical simulation of the sucker-rod pumping system (2014)

The sucker rod pump is an artificial lift method frequently applied in onshore petroleum wells. This system can be described using a numerical simulation based on the behavior of a rod string. In the past, the elastic behavior of the rod string made it difficult to model the system. However, since the 1960s and with the advent of digital computers, it has been modeled numerically. The rod string be-haves like a slender bar, and thus, the propagation of elastic waves along the bar can be represented by a one-dimensional equation. Gibbs (1963) presented a mathematical model based on the wave equation, which is described on the basis of the analysis of forces on the rod string and is incorporated into a boundary value problem involving partial differential equations. The use of the finite differ-ence method allows for a numerical solution by the discretization of the wave equation developed in the mathematical formulation with appropriate boundary and initial conditions. This work presents a methodology for implementing an academic computer code that allows simulation of the upstroke and downstroke motion of the rod string described by the wave equation under ideal operating conditions, assuming a harmonic motion of the rod at one end and downhole pump at the other end. The goal of this study is to generate the downhole dynamometer card, an important and consolidated tool that controls the pump system by diagnosing oper-ational conditions of the downhole pump.

Maturation-associated changes in the response of the salmon testis to the steroidogenic actions of gonadotropins (GTH I and GTH II) in vitro (1995)

Previous studies from our laboratory have shown that salmon gonadotropins GTH I and GTH II have similar effects on testicular steroidogenesis in vitro. To determine whether the relative potencies of GTH I and GTH II changed during late stages of spermatogenesis, the effects of GTH I and GTH II on in vitro steroid production by testicular tissue from fish in stages IV to V of spermatogenesis were examined. Fragments of testicular tissue were incubated with GTH I and GTH II for 18 h at 15 degrees C. The in vitro production of 11-ketotestosterone (11-KT), testosterone (T), 17 alpha-hydroxyprogesterone (17OH-P), and 17 alpha,20 beta-dihydroxy-4-pregnen-3-one (17,20 beta-P) was determined by RIA. GTH I and GTH II were equipotent in stimulating the production of 11-KT, T, and 17,20 beta-P (17OH-P was not detectable) by testicular tissue in stage IV of spermatogenesis. The sensitivity of testicular tissue to the steroidogenic effects of GTH II increased as spermatogenesis progressed. In contrast, the sensitivity of testicular tissue to the effects of GTH I on 17,20 beta-P production declined from stages IV to V, while the sensitivity of testicular tissue to the effects of GTH I on 11-KT production remained unchanged. These changes in sensitivity to GTH I and II are consistent with previously reported changes in GTH receptors in salmon testis and support the hypothesis that GTH I and GTH II may have different roles during spermatogenesis.
Flagella number among Naegleria flagellates. (1991)

Scanning electron microscopy was used to determine the number of flagella on the flagellates of Naegleria australiensis, N. fowleri, N. gruberi, and N. jadini. Although the majority of flagellates had 2 flagella, there was considerable variation among individual cells. The number of flagella per flagellate varied from 1-8, with 2.4 being the average number per cell. For the different species, the average number of flagella per cell ranged from 2.0 in N. jadini to 3.1 for N. australiensis. The greatest amount of variation occurred in N. australiensis, with only 43% of the cells having 2 flagella. By contrast, 92% of N. fowleri cells had 2 flagella. Naegleria jadini and N. gruberi were intermediate with 80% and 74% biflagellates, respectively.
RELATIONSHIP OF THE BACTERIA INHIBITING PLAQUE FORMATION AND THE NUMBER OF ORAL BACTERIA (1999)

The inhibition degree of the isolated bacteria on plaque formation of Streptococcus mutans, and the effect of these bacterial genus on the concentration of total bacteria in saliva were assessed with the following. The effectiveness of the isolated bacteria on the inhibition of plaque formation was assessed culturing Streptococcus mutans in the beaker with orthodontic wires. The mean weight of plaque produced on a wire was 152mg in the culture of Streptococcus mutans only, whereas being reduced to 4mg, 78mg, or 72mg in the combined culture of Streptococcus mutans and Enterococcus durans, Lactobacillus acidophilus, or Streptococcus oralis. The colony forming units (CFU) of Streptococcus mutans were per ml in the culture of Streptococcus mutans, only, wheras being per ml in the combined culture of Streptococcus mutans and Enterococcus durans, Lactobacillus acidophilus, or Streptococcus oralis. When saliva from children was inoculated on brain heart infusion agar, the colony forming units of bacteria were per ml of saliva. The concentration of Enterococcus, Lactobacillus, or Streptococcus inhibiting Streptococcus mutans in saliva was not proportioned to that of total bacteria replicated on brain heart infusion agar. These results indicate that the isolated bacteria inhibited the replication of Streptococcus mutans, resulting into inhibiting the formation of plaque, but the concentration of Enterococcus, Lactobacillus, or Streptococcus inhibiting Streptococcus mutans, in saliva might not affect the total bacterial concentration of saliva.
Bradykinin and cardiovascular system: estimation of half-life (1962)

Synthetic bradykinin in postpartal women produced a decrease in systolic and diastolic blood pressure, reduction of pulse pressure, and increased heart rate and respiration. The threshold dose for single intravenous injections was approximately 0.1 µg/kg, and that for intravenous infusions approximately 0.125 µg/kg/min. For the change in diastolic blood pressure, a linear dose-response curve was found in the semilogarithmic system in the range of 0.125– 1.25 µg/kg/min. In intravenous infusions, the maximal effect appeared, regardless of the dose, after 2–3 min. The time interval between starting the infusion and the onset of effect was distinctly dependent on the dose. These observations indicate exponential elimination or inactivation. Using a formula applicable to exponentially eliminated substances, a threshold level of 0.1 µg/kg and a half-life shorter than 0.5 min were estimated.
Pseudomosaicism, true mosaicism, and maternal cell contamination in amniotic fluid processed with <i>in situ</i> culture and robotic harvesting (1992)

This study was designed to test the usefulness of the common definitions for maternal cell contamination, true mosaicism, and pseudomosaicism for amniotic fluid specimens processed by in situ culture and robotic harvesting. We prospectively studied 4309 consecutive amniotic fluid specimens processed with these methods and found that 0.84 per cent had maternal cell contamination, 0.28 per cent had true mosaicism, and 5.4 per cent had pseudomosaicism. Although the frequencies of maternal cell contamination and true mosaicism were comparable to those in similar published studies, the frequency of pseudomosaicism was more than twice as high as that in previous reports. This finding is most likely not due to the method, but rather to a more accurate estimate of the actual frequency of pseudomosaicism in amniotic fluid cultures than reported heretofore. Follow-up clinical information was available on 72 per cent of the cases. In three cases of true mosaicism involving structural anomalies, the results of cytogenetic follow-up studies on the neonates were normal. None of the pseudomosaic cases involving trisomy 8, 13, 18, or 21; triple X; or monosomy X were associated with newborns who had birth defects.
Geopolitics, Moral Reform, and Poetic Internationalism: Liang Qichao’s The Future of New China (2012)

Liang Qichao's novel The Future of New China views culture and commerce in international contexts under the rubric of datong. While the novel begins with a scene of cultural exchange and commerce, it soon centers on the foreign education and travel of two young protagonists, who are to become the founding fathers of a constitutional nation-state. The urgency of nation building plays out in the two young men's over the political, moral or populist means of achieving the nation. How does nation-state building relate to the initial datong cosmopolitanism? This paper suggests that Liang's nation contains international dimensions. The new Chinese nation is situated in a geopolitical network of nation-states, but it also aspires to self-determination and equality with other nations. The nation is to be built by resorting to a moral reform that contains the idea of tianxia (all under heaven). In his Discourse on the New Citizen, Liang calls for personal outlooks based on culture and morality rather than institutions or actual politics. The novel analyzes China's debates on reform and revolution; the present paper traces the connection between this moral quality of a nation and internationalism. I contend that Liang's nation-building projects an international type of aspiration toward tianxia.
CADIC: computer-aided design on internet with cryptosystem (2002)

Computer-aided design of integrated circuit on the Internet explores new frontiers in the design environment. A new hypermedia CAD system is introduced in this paper promoting distributed design collaboration, remote command executions, and automatic exchange of design data. The proposed organization is implemented using the World Wide Web and the client server communication protocol. The security has been a problem in exchange of data through the Internet. The proposed CAD system alleviates the security problem using the combined system of One-Time Password (OTP) and the RC4 encryption algorithm. Our system is fast and reliable enough to design and provide electronic commerce services of intellectual property blocks on the Internet.

Susceptibility of cats to infection with Ehrlichia risticii, causative agent of equine monocytic ehrlichiosis (1988)

Eight adult cats were inoculated IV (n = 6) or SC (n = 2) with Ehrlichia risticii-infected P388D1 (continuous murine macrophage) cells or with E risticii released from P388D1 cells. Three additional cats were inoculated with organism-free P388D1 cultured monocytes, and 1 cat, which served as a medium control was inoculated with balanced salt solution. Clinical signs of illness were observed in the IV inoculated cats from which E risticii was isolated. One cat developed intermittent diarrhea between postinoculation days (PID) 8 and 18, and the other cat developed lymphadenopathy, acute depression, and anorexia between PID 20 and 24. Ehrlichia risticii was isolated in cultures from 2 of 6 IV inoculated cats on PID 6, 10, and 17. Both cats were inoculated with E risticii released from the P388D1 cells. Ehrlichia risticii was not isolated from SC inoculated cats or from control cats. All 8 cats inoculated with E risticii seroconverted between PID 10 and 23. A pony inoculated with E risticii isolated from 1 of the inoculated cats developed clinical signs of equine monocytic ehrlichiosis including fever, anorexia, depression, and mild colic. Ehrlichia risticii was isolated from the blood of this pony on PID 7, 9, 11, and 16.
Quantitative contrast‐enhanced MRI with superparamagnetic nanoparticles using ultrashort time‐to‐echo pulse sequences (2014)

This ability to longitudinally quantify blood pool CA concentration is unique to quantitative UTE contrast-enhanced (QUTE-CE) MRI and makes QUTE-CE MRI competitive with nuclear imaging.
Diphendramine Hydrochloride Oral Dispersible Tablets: Preparation and Evaluation (2014)

The purpose of this research was to make an attempt to develop mouth dissolving tablets of diphenhydramine hydrochloride. Mouth dissolving tablet offers a solution for pediatrics, adolescents and geriatrics patients those have difficulty in swallowing tablets/capsules, resulting in improved patient compliance. Diphenhydramine is used as anti emetic, anti tussive for dermatosis and pertusis and for hypersensitivity reactions. The aim is to formulate different formulations of mouth dissolving tablets of diphenhydramine hydrochloride using different superdisintegrants like crospovidone and croscarmellose sodium and subliming agent menthol, by direct compression and sublimation method. Precompression parameters were characterized for flow properties and prepared tablets were evaluated for hardness, thickness, friability, weight variation, wetting time, water absorption ratio, drug content, disintegration time and dissolution studies. Invitro dissolution studies show that release in tablets with a combination of superdisintegrant and subliming agent was good. Among all the formulations, F9 (10% crospovidone and menthol)showed maximum drug release of 99.76% in 12 min. Hence it is evident from this study that mouth dissolving tablets could be a promising delivery system for diphenhydramine hydrochloride with good mouth feel and improved drug bioavailability with better patient compliance.
VLSI implementation of the motion estimator with two-dimensional data-reuse (1998)

This paper describes the VLSI implementation with a two-dimensional (2-D) data-reuse architecture for a full-search block-matching algorithm. Based on a one-dimensional processing element (PE) array and two data-interlacing shift-register arrays, the proposed VLSI architecture can efficiently reuse data to decrease external memory accesses and save the pin counts. It also achieves 100% hardware utilization and a high throughput rate. In addition, the same chips can be cascaded for different block sizes, search ranges, and pixel rates.
Investigation of a horn antenna fed by several waveguides (2009)

A pyramidal horn antenna fed by Dolph-Chebyshev amplitudes and equal phases via some adjacent H-plane coupled rectangular waveguides was simulated and measured. The simulation has been performed horn fed by 8 and by for 4 waveguides. Building and measuring were done for the 4 waveguides antenna. The measured gain of the horn fed by 4 waveguides was approximately 16 dBi, about 4 – 6 dB more than the gain of a conventional horn antenna having the same volume. The measured sidelobe level in the H-plane of this antenna was approximately 20 dB. Good agreement between simulation and measurement was achieved

Laser surgery of the vocal cordsAn experimental study with carbon dioxide lasers on dogs (1972)

Abstract In experiments on dogs, a focused beam from a continuous wave surgical carbon dioxide laser integrated with an operating microscope was used selectively to evaporate predetermined amounts of normal vocal cord tissue through a laryngoscope. This mode of tissue removal was precise, rapid and practically bloodless. Microscopic laryngoscopy examinations and histological work‐up one, two and three weeks postoperatively indicated normal healing similar to that of clean surgical wounds.
Predistorted Waveguide Filters for Use in Communications Systems (1969)

Predistortion is a standard technique for correcting the effects of energy dissipation in filters, making their response conform to that of ideal filters. The problem of dissipation is particularly noticeable in narrowband bandpass filters used in microwave communications systems. Dissipation makes the passband edges slump downward, as shown in Figure 1, which can cause distortion and intermodulation. In predistorting a filter, we allow for dissipation in the initial design. A response approximating the ideal response can be approximated at the price of increased insertion loss. The flat response of predistorted filters is advantageous when used in high-capacity microwave communications systems; however, the filters have an additional property which makes them especially attractive for certain applications in microwave communications systems.
Dysfunction of the ubiquitin–proteasome system in multiple disease conditions: therapeutic approaches (2008)

The ubiquitin-proteasome system (UPS) is the major proteolytic pathway that degrades intracellular proteins in a regulated manner. Deregulation of the UPS has been implicated in the pathogenesis of many neurodegenerative disorders like Alzheimer's disease, Parkinson's diseases, Huntington disease, Prion-like lethal disorders, in the pathogenesis of several genetic diseases including cystic fibrosis, Angelman's syndrome and Liddle syndrome and in many cancers. Multiple lines of evidence have already proved that UPS has the potential to be an exciting novel therapeutic target for the treatment of these diseases. Here I review how aberrant functions of various genes have implicated UPS in many human disorders including neurodegeneration and cancers. I also discuss the finding that some proteasome inhibitors possess a therapeutic potential as drugs against many such diseases.
A performance model for software focused supply chains (2005)

Software focused products such as iPods, DVD players, etc. have emerged a lot in the markets. The study on the supply chain of software focused products and service has become to attract a lot of research attentions. In this paper, we summarize the general features of software focused products and the features of software focused supply chains. We then propose a performance model to describe the performance of traditional supply chains and the performance of software focused supply chains. With this model, the bottlenecks of software focused supply chains can be easily located and the overall supply chain performance can be improved.
