ASRPAKE: An Anonymous Secure Routing Protocol with Authenticated Key Exchange for Wireless Ad Hoc Networks (2007)

In this paper, we present a novel anonymous secure routing protocol for mobile ad hoc networks (MANETs). The proposed protocol not only provides anonymity from all the intermediate nodes, but also integrates the authenticated key exchange mechanisms into the routing algorithm design. Furthermore, a new attack on anonymous services, called snare attack, is introduced, where a compromised node lures a very important node (VIN) into communicating with him and traces back to the VIN by following the route path. An adversary can then snare the VIN and launch decapitation strike on the VIN. Finally, we present a novel DECOY mechanism as a countermeasure to enhance anonymity of VINs and defeat snare attack.
Effects of Different Levels of Supplementary Alpha-amylase on Digestive Enzyme Activities and Pancreatic Amylase mRNA Expression of Young Broilers (2008)

Four hundred and forty 1-day-old Arbor Acre broilers were fed commercial starter diets with 0, 250, 750 and 2,250 mg/kg of an alpha-amylase preparation from 1 to 21 days of age to investigate the effects of an exogenous enzyme on growth performance, activities of digestive enzymes in the pancreas and anterior intestinal contents and pancreatic amylase mRNA expression. Body weight gain (BWG) and average daily gain (ADG) increased linearly (p<0.01) with increasing levels of supplementary amylase but feed conversion ratio (FCR) was not affected. There was a negative quadratic change of protease and amylase in the small intestinal contents with the increase of supplementary amylase level. The activity of intestinal trypsin was also increased (p<0.05). Lipase was unaffected by amylase supplementation (p>0.05). The pancreatic protease, trypsin, and lipase were not affected by exogenous amylase levels. Consistent with the tendency for a linear depression of amylase activity, pancreatic -amylase mRNA was down-regulated by dietary amylase supplementation. The present study suggested that oral administration of exogenous amylase affected activities of intestinal enzymes and the production of pancreatic digestive enzymes in a dose-dependent manner.
Cloud Hooks: Security and Privacy Issues in Cloud Computing (2011)

In meteorology, the most destructive extratropical cyclones evolve with the formation of a bent-back front and cloud head separated from the main polar-front, creating a hook that completely encircles a pocket of warm air with colder air. The most damaging winds occur near the tip of the hook. The cloud hook formation provides a useful analogy for cloud computing, in which the most acute obstacles with outsourced services (i.e., the cloud hook) are security and privacy issues. This paper identifies key issues, which are believed to have long-term significance in cloud computing security and privacy, based on documented problems and exhibited weaknesses.

THE CHROMOSOMES OF TURKEY EMBRYOS DURING EARLY STAGES OF PARTHENOGENETIC DEVELOPMENT (1981)

In the early stages of parthenogenetic development in turkey eggs, many blastoderms are mosaics of haploid, diploid and polyploid cells. The genome composition of these blastoderms can be identified by C-banding. They may be generally described as either A-Z/2A-ZZ/nA-nZ or A-W/2A-WW/nA-nW and are found in a nearly 1:1 ratio. The blastoderms showing the W body (W+) become lethal within two days of incubation. The haploid cell proportion decreases rapidly during the early stage of development, and, as haploid cells decrease, the proportion of polyploid cells appears to increase. At six days of incubation, various kinds of parthenogenetic development can be observed. Their genome compositions are either diploid (2A-ZZ) or mosaic (A-Z/2A-ZZ). These findings suggest that diploid parthenogenesis occurs by either suppression of meiosis II or chromosome doubling some time after the first cleavage division. The frequent occurrence of mosaic blastoderms indicates that the majority, if not all, of the parthenogenetic embryos initiate their development in haploid ova.
Ethene Adsorption and Decomposition on the Cu(410) Surface (2009)

The influence of open steps on the surface properties is shown by investigating the interaction of molecular ethene with Cu(410). We find a surprisingly low-temperature, site-selective chemistry at the strongly under-coordinated step sites. Ethene bonds either in a π-bonded or in a di-σ-bonded state or undergoes complete dehydrogenation. All pathways involve the low-coordination sites at the step, since the first species is partially stabilized with respect to low-Miller-index surfaces, while the other two are observed only on Cu(410). When annealing the surface, dehydrogenation and transformation into the di-σ-bonded moiety proceed, both processes being favored by faster heating rates. The so-generated carbon (presumably C2 admolecules) decorates the step edges, thereby blocking the active sites for subsequent dissociation and permitting only π-bonding of ethene. The dipole loss of carbon disappears in high-resolution electron energy loss spectroscopy when annealing to room temperature, indicating that carbon moves to more coplanar or even to subsurface sites where it still influences the surface chemistry. The surface reactivity is recovered when heating the crystal to 900 K since C dissolves then deep enough into the bulk.

Future Directions and Issues (2005)

Attend a conference or seminar about the future of law and journalism, and it's a fair bet the talk will turn to televising courts. Cameras have been allowed in various Australian courts, mainly broadcasts of judgments and sentencing decisions, footage taken at the start of proceedings, and ceremonial occasions. Writing in 1995, Justice Michael Kirby speculated on the inevitability of cameras in court. He mentioned the Bobbit and O. J. Simpson cases from the United States and described the controls needed to stop the unacceptable distractions of wandering camera operators, whose presence might affect the testimony of witnesses. Almost ten years later, camera access is regular, though still tightly controlled. Australian television has no station which markets live broadcasts of the most spectacular murder trials.
[Integration activities of a central municipal hospital]. (2001)

Scientifically-based integration of therapeutic and prophylactic institutions is needed for better meeting the population requirement of medical care, and it is desirable to unite the financial resources and personnel; such is the objective reality for municipal therapeutic and prophylactic institutions of local public health systems. In order to make medical care available for the population and to ensure its high quality, structural changes in the public health of a region are needed. These changes include integration of medical services of these territories; creation of a network of therapeutic and prophylactic institutions corresponding to medical demographic structure of population, so that the scope of medical care be increased and specialized care made easier available for the population; and creation of the optimal managing system. Comparative studies of population health and its time course, public health organization at neighboring territories, where therapeutic and prophylactic institutions, such as Central Municipal Hospital and Central Regional Hospital have autonomous managing and financing, confirmed the need in integration of public health units functioning at a certain territory into a universal system, and in development of approaches to overcome the present-day miscellaneous network by integrating the activities of treatment-and-prophylaxis institutions. Identical economic, geographic, and macroeconomic living conditions of the population, similarity of medical demographic structure and similar changes in it, as well as similar morbidity structure, are sufficient grounds for integration of public health services.
Using a pulsed supply voltage for delay faults testing of digital circuits in a digital oscillation environment (2003)

High-performance digital circuits with aggressive timing constraints are usually very susceptible to delay faults. Much research done on delay fault detection needs a rather complicated test setup together with precise test clock requirements. In this paper, we propose a test technique based on the digital oscillation test method. The technique, which was simulated in software, consists of sensitizing a critical path in the digital circuit under test and incorporating the path into an oscillation ring. The supply voltage to the oscillation ring is then varied to detect delay and stuck-at faults in the path.

The Effects of the Social Context on Pre-Decisional Processes of Protective Action in Beijing Communities (2016)

This paper examined the effects of the social context (media communication, face-to-face communication, and friend and kinship network) on pre decisional processes of individual protective action. A two-stage survey was carried out aimed at residents in Beijing communities in half a year, and then the data were disposed from three aspects: Common Method Variance, non-parametric test, and Exploratory Factor Analysis. Based on the pretest data (N=344) and the posttest data (N=351), analyses were implemented from aspects of competing model analysis, hypothesis path test, and Multiple Group Analysis with the method of Structural Equation Modeling. Results: First, media communication activities can influence individual reception of risk information, which influence is the strongest among social context variables; moreover education attainment and age can influence it significantly. Then media channel should be diverse with respect to the different groups in order to increase the degree of information reception. Second, face-to-face communication activities can influence individual attention behavior; at the same time, it can also influence media communication; in addition, education attainment and income level are can influence it significantly. Then physical activities should be specific with respect to different socioeconomic strata in order to raise the degree of information attention. Third, friendly and kinship network does not influence any pre decisional processes variable, but it can influence face-to-face communication instead. Then it can be seen that the role of social conformity should be emphasized in order to enhance the degree of individual participation. Fourth, no social context variable can exert significant influence on comprehension behavior. Then it can be seen that the literal problem should be emphasized in order to improve the degree of understanding of risk communication. Future research should cover the particular social context as regards demographic characteristics, the facilitating and barriers inside risk information, and the relationship between social conformity and risk communication.
Seasonal Variation in Heavy Metal Removal Efficiency and Application of Risk Assessment for Constructed Wetlands (2010)

본 연구는 자유수면형 인공습지에서의 시기적인 중금속 제거율의 변동을 평가하기 위하여 수행되었다. 대상 인공습지의 유입수는 하수처리수가 포함된 하천수이다. 인공습지에는 갈대 (Phragmites australis)와 부들 (Typha latifolia)이 주로 분포하며, 이들 두 종은 습지의 95 % 이상을 차지하는 우점종이다. 2009년 5월부터 9월까지 습지의 유입과 유출부분에서 유입수와 유출수를 시료 채취하였다. 채취된 시료는 ICP-AES 방법을 이용하여 6가지 중금속을 분석하였으며, 위해성 평가를 이용하여 카드뮴 (Cd), 크롬 (<TEX>$Cr^{+6}$</TEX>), 비소 (As), 납 (Pb), 니켈 (Ni), 구리 (Cu)의 분석 결과를 평가하였다. 위해성평가는 농부와 레크리에이션에 대한 두가지 시나리오를 바탕으로 이루어졌다. 연평균 중금속 제거율은 계절적인 변화 측면에서 큰 변화를 나타내지 않았다. 위해성 평가 결과 시료가 채취된 부분 및 계절적인 변화 대부분에서 US EPA의 기준인 <TEX>$10^{-4}$</TEX>를 초과하지 않는 수준으로 허용가능한 수준이었다. 하지만, 봄철 농부에 대한 위해성평가 결과 위해도가 <TEX>$10^{-4}$</TEX> 수준이며, <TEX>$10^{-6}-10^{-8}$</TEX> 수준은 질병의 이동이 우려되는 수준 (US EPA)임을 감안하여, 인공습지에 중금속 농도 저감 시설의 설치를 고려해야 한다. 본 연구에서는 위해성 평가를 가상의 시나리오에 적용하여 평가를 시도함으로서, 수치적인 자료로 제시할 수 있을 뿐만 아니라 중금속의 정량적인 평가를 수행할 수 있었다. 따라서 위해성 평가는 인공습지의 안전성에 대하여 대중과 소통할 수 있는 도구로서 이용할 수 있으며, 인공습지의 효율적인 운영 및 현장 적용에 있어서 스크리닝 도구로서의 역할이 가능할 것으로 판단된다.
[Detection of integration status of human papillomavirus 16 in cervical precancerous lesions]. (2005)

HPV16 integration into the host genome is already present in some of CIN lesions. The multiplex PCR estimation of the HPV L1, HPV16 E2, E6 genes and E2/E6 ratio could be a simple method for detecting HPV/HPV16 infection and its integration status in liquid-based residual samples. It would be a helpful complementary tool for cytological screening to identify those patients at high risk of developing high-grade squamous intraepithelial lesions and cervical cancer.
Sodium hyaluronate in equine traumatic arthritis. (1980)

Thirty seven intra-articular injections, each 2 ml sodium hyaluronate were made into 21 arthritic joints in 15 racing Thoroughbreds and one part-bred polo pony. One joint failed to improve at all, 16 became sound with one injection, 4 became sound with 2 injections, and 11 joints showed various degrees of response. Eleven of 14 horses became sound for flat racing. Discussion relates to the technique of using sodium hyaluronate, some clinical and pathological aspects of traumatic arthritis, joint lubrication and a brief review of some properties of sodium hyaluronate which have a bearing on arthritis.
Preventing gelation in polyisoimide synthesis (2000)

The origin of the gel formation during the conversion of poly(amic acid)s to polyisoimides, and methods for its prevention are described. The gelation behaviour was studied as a function of the cyclodehydration temperature, the concentration and end-groups of 4,4′-oxydianiline/4,4′-oxydiphthalic anhydride poly(amic acid) systems, using 1,3-dicyclohexylcarbodiimide as a dehydrating agent. The 1H NMR spectroscopic data showed that gel formation during polyisoimide synthesis results from the amide formation reaction of terminal amine groups with acylated poly(amic acid)s. Dilution of poly(amic acid) solutions and lowering cyclodehydration temperatures retarded gelation. However, complete prevention of gel formation at relatively high concentration (15%) and temperature (20 °C) was achieved only for phthalic anhydride end-capped polyamic systems. © 2000 Society of Chemical Industry

DNA polymerases from bakers' yeast. (1977)

Two DNA polymerases are present in extracts of commercial bakers' yeast and wild type Saccharomyces cerevisiae grown aerobically to late log phase. Yeast DNA polymerase I and yeast DNA polymerase II can be separated by DEAE-cellulose, hydroxylapatite, and denatured DNA-cellulose chromatography from the postmitochondrial supernatants of yeast lysates. The yeast polymerases are both of high molecular weight (greater than 100,000) but are clearly separate species by the lack of immunological cross-reactivity. Analysis of associated enzyme activities and other reaction properties of yeast DNA polymerases provides additional evidence for distinguishing the two species. Enzyme I has no associated nuclease activity but does carry out pyrophosphate exchange and pyrophosphorolysis reactions, and has an associated 3'-exonuclease activity. Enzyme I does not degrade deoxynucleoside triphosphates and cannot utilize a mismatched template. Enzyme II does carry out a template-dependent deoxynucleoside triphosphate degradation reaction and can excise mismatched 3'-nucleotides from suitable template systems. Earlier studies have shown that both Enzyme I and Enzyme II are inhibited by N-ethylmaleimide. The yeast enzymes are not identical to any known eukaryotic or prokaryotic DNA polymerases. In general, Enzyme I appears to be most similar to eukaryotic DNA polymerase alpha and Ezyme II exhibits properties of prokaryotic DNA polymerases II and III.
Measurement of rCBF by H2 clearance: theoretical analysis of diffusion effects. (1982)

Although experimental evidence now indicates that diffusion of hydrogen can influence the measured clearance curves from which local blood flow is inferred, its exact role has not yet been well defined. For this reason we have developed a theoretical treatment of the effects of diffusion near a boundary separating regions of inhomogeneous perfusion (e.g. the gray-matter interface), and reexamined the appropriateness of the currently used bi-exponential model. Using our model, we confirmed empirical estimates of important diffusion effects up to approximately 2 mm from an inhomogeneity, and further refined the concept of spatial resolution. We also showed that fitting data to bi-exponential curves may be incorrect and lead to inaccurate results. We conclude from these studies that diffusion does indeed have an important effect on the clearance curves measured near an inhomogeneity.
A Short-Wave Single-Side-Band Radiotelephone System (1938)

There is described briefly a short-wave single-side-band system which has been developed for transoceanic radiotelephone service. The system involves the transmission of a reduced carrier or pilot frequency and is designed to include the testing of twin-channel operation wherein a second channel is obtained by utilizing the other side band. The paper indicates the reasons which led to the selection of this particular system and discusses at some length those matters which require agreement between the transmitting and receiving stations when single-side-band transmission is employed.
Mechanical characterization and experimental modal analysis of 3D Printed ABS, PC and PC-ABS materials (2020)

Abstract Additive manufacturing (AM) process builds the parts, layer by layer precisely from Computer-Aided Design (CAD) models, whereas traditional subtractive manufacturing process removes layers from materials to attain the desired shape. Of late Rapid prototyped (RP) parts are used for the direct production of components for manufacturing and testing in the industries. Understanding material, machine used along with the process variables that affect the strength of the final part gains importance as the parts can be printed directly from CAD data and effectively integrated into structures. The main aim of this investigation is to present the mechanical characterization and free vibration analysis of various 3D printed Engineering Plastic Materials. Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), and Polycarbonate–Acrylonitrile Butadiene Styrene (PC-ABS) materials are used in this study. Spools are prepared from plastic pellets using wire extruder. Tensile tests have been performed on dog bone specimens to evaluate strength, fractured specimen’s surfaces which are further evaluated using Field Emission Scanning Electron Microscope (FESEM) to explore fracture of the raster and bonding between layers. From the experimental results it’s noticed that the PC-ABS material exhibits improved elastic limit and load-carrying capacity compared with ABS and PC. Three types of beams are fabricated using different materials and modal analysis has been conducted to predict the stiffness of beams in terms of natural frequencies under clamped free (CF) and clamped clamped (CC) end conditions. Higher natural frequencies observed with PC-ABS is compared with the rest of the materials.
A power control algorithm in wireless communication systems (2010)

A novel distributed power control algorithm based on interference estimation is presented for wireless cellular system. A classical result of stochastic approximation is applied in this scheme. The power control algorithm is converted to seeking for zero point problem of a certain function. In this distributed power algorithm, each user needs only to know its own channel gain to its assigned base station and its own matched filter output at its assigned base station to update its power. Hence, the proposed algorithm is robust.
An Analysis of Transaction Logs to Evaluate the Educational Needs of End Users (1992)

End users at the University of Southern California (USC) have free access to the last ten years of MEDLINE through a local online system known as USCInfo. Librarians at USC Norris Medical Library provide documentation and offer formal and informal training on the use of the system to search MEDLINE. To assess the educational needs of the end users, 643 searches were analyzed. Although a high proportion (84%) of the searches were judged to be successful, the use of medical subject headings (MeSH) to obtain optimal results was low; only 20% of all successful subject searches employed MeSH. Also, the advanced features of the system were underutilized. While it is promising to learn that many end users are obtaining positive results, methods which will encourage end users improve their retrievals need to be developed.
Pressure control devices with the microprocessor error correction (2005)

The use of microprocessors in pressure control devices is necessary to improve its accuracy, provide long-term stability, and satisfy modern requirements when the digital signal protocol needs reprogramming. By using complementary MOS structure microprocessors and decreasing the working frequency, the electronic module power consumption may be decreased. Nevertheless, the reduced processor speed allows doing the full cycle of design-measuring procedures 3-5 times per second and correcting DAC with the same speed. Microprocessor pressure control devices have some common procedures: the calibration procedure, resulting in the form of the sensitive element mathematical model characteristic and some adjustments of the device; the characteristic approximation procedure on base of the sensitive element error correction mathematical model; the measurement result-engineering unit transformation procedure; the forming of analog digital signals of interface.
