Illegal Access Point detection using clock skews method in wireless LAN (2014)

Illegal Access Point called as Rogue Access Point (RAP) is an access point that has been installed on a secure network without explicit authorization from a system administrator Wireless Networks has big security threat called Rough access points. If care is not taken and if this network threats are not detected and mitigated on time, this will result into the serious network damage and data loss. Every organization should give priority for Finding and avoiding rogue wireless access points. For detection of unauthorized AP', we have use clock skew as a parameter of a wireless access point (AP). For detecting Rogue access point using clock skews method in wireless LAN network overcomes the limitations of existing solutions. For calculating clock skew of AP, we have use IEEE 802.11 Time Synchronization Function (TSF) time stamps sent out in the beacon/probe response frames. We mainly focus on implementation of least-square fit method for this purpose though we have explain both approach for detecting clock skew From this studies we came to known that use of clock skews appears to be an effective and robust method for detecting fake AP's in wireless local area networks.
The viscoelastic properties of rubber–resin blends. II. The effect of resin molecular weight (1985)

Abstract In blends of rubber and low molecular weight resins, the compatibility of the system controls the viscoelastic properties and ultimately the performance of the composition as a pressure sensitive adhesive. The effect of the resin molecular weight on compatibility was examined by studying rubber–resin blends prepared from resins which represent a range of molecular weights. Viscoelastic properties were measured using a mechanical spectrometer on 1:1 blends of rubber and a series of polystyrene resins and poly(vinylcyclohexane) resins. Based on plots of G ′ and tan δ vs. temperature, blends of natural rubber and polystyrene resin show incompatibility at resin M w of about 600 and above. Blends of natural rubber and poly(vinyl cyclohexane) are incompatible at resin M w of about 1800, but are compatible at M w of about 650. Blends of styrene–butadiene rubber and polystyrene resins are compatible at resin M w of about 650 but appear to contain a low volume incompatible phase at M w of about 900. Therefore, the compatibility of a rubber–resin blend depends upon the molecular weight of the resin. Even systems expected to be compatible will show evidence of incompatibility as the molecular weight of the resin is raised above some limiting value.
Microwave-Assisted Addition of Pyrroles to Electron-Deficient Olefins: A Rapid Entry to<i>C</i>-Alkyl Pyrroles (2005)

A general procedure for the Michael addition of pyrroles with electron-deficient olefins using silica gel supported reagent under microwave irradiation, has been developed. This new method is fast, efficient, environmentally benign and solvent-free. A catalytic amount of BiCl3 is employed for moderately bulk electron-deficient olefins.
Solar magnetic and velocity-field measurements: new instrument concepts (1984)

Using a generalized Mueller calculus, a number of new instrument concepts for the recording of solar magnetic and velocity fields are treated: (1) Schemes for the simultaneous recording of all four Stokes parameters, in particular solutions requiring only one piezoelastic modulator, and systems using the beat frequencies of two modulators (to obtain compatibility with the slow readout rate of large array detectors). (2) A system using a solid polarizing Michelson interferometer in combination with broadband prefilters and piezoelastic modulators. (3) A white-light solar magnetometer, an instrument without any spectrally resolving element at all.
A prediction algorithm for coexistence problem in multiple WBANs environment (2014)

Coexistence problem occurs when a single WBAN(Wireless Body Area Network) locates in multiple WBANs environment. In that case, WBANs are suffered from serious channel interferences which may degrade the performance of each WBAN due to failure of data transmission. Because WBAN handles physical signal or emergency data affecting human life, WBAN requires the detection of coexistence condition to guarantee reliable communication continuously for each sensor node of WBAN. In this paper, we present a prediction algorithm to detect coexistence problem efficiently in multiple WBANs environment. The algorithm measures PRR(Packet Reception Ratio) and SINR(Signal to Interference and Noise Ratio) to detect interference reliably. In order to handle coexistence problem efficiently, the algorithm employs the naive Bayesian classifier which is one of machine learning techniques to classify the coexistence condition into four states. We conduct extensive simulations for coexistence detection with various packet transmit rates of sender node and speeds of mobile WBAN by using Castalia 3.2 simulator based on OMNet++ platform. Consequently, we demonstrate that the proposed algorithm provides more reliable and accurate performance than existing studies to detect coexistence in multiple WBANs environment.
Characterization of Semi‐Insulating Polycrystalline Silicon Prepared by Low Pressure Chemical Vapor Deposition (1993)

We employed the multiple angle incident ellipsometer to study the growth mechanism and optical properties of semi‐insulating polycrystalline silicon (SIPOS) films deposited by the low‐pressure chemical vapor deposition (LPCVD) technique. A significant difference of the imaginary part of the refractive index between film at the edge and those in the central region of the wafer was observed. Our analyses showed that it was consistent with the depletion model. This depletion phenomenon was confirmed by Auger analysis. Moreover, we found that spatial depletion at the edge of the wafer was greatly influenced by the flow rate of to gases. Excessively high flow rate suppressed the silicon microcrystal formation, resulting in a thinner SIPOS film.
Local Multipoint Communications Systems: Network System Architectures For Broadband Internet Access (1998)

LMCS (local multipoint communications systems) network architectures for Internet access are designed based on the Korean government frequency allocation notice[ 11. The parameters of frame structures, modulation demodulation methods, and MAC protocol are selected from DAVIC specification[2], and the protocol structures for Internet access are designed using internetworking protocols between IP and ATM.
Pneumocele of the maxillary sinus. (1980)

Since 1974, four cases of pneumocele of the maxillary sinus have been reported. An air contained sac, the pneumocele erodes bone and presents with cheek swelling, facial fullnss, or pain. This report documents a case of pneumocele of the maxillary sinus and outlines diagnostic and therapeutic guidelines. Caldwell-Luc with nasal antrostomy is curative.
Melanin is an essential component for the integrity of the cell wall of Aspergillus fumigatus conidia (2009)

These results suggest that, in addition to a protective role against the host's immune defences, melanin is also a structural component of the conidial wall that is required for correct assembly of the cell wall layers and the expression at the conidial surface of adhesins and other virulence factors.
2-Chloro-2,2-difluoroacetophenone:  A Non-ODS-Based Difluorocarbene Precursor and Its Use in the Difluoromethylation of Phenol Derivatives (2006)

A novel and non-ODS-based (ODS = ozone-depleting substance) preparation of 2-chloro-2,2-difluoroacetophenone (1) was achieved in high yield by using 2,2,2-trifluoroacetophenone as the starting material. Compound 1 was found to act as a good difluorocarbene reagent, which readily reacts with a variety of structurally diverse phenol derivatives 4 in the presence of potassium hydroxide or potassium carbonate to produce aryl difluoromethyl ethers 5 in good yields. This new and easy-to-handle synthetic methodology offers an environmentally friendly alternative to other Freon- or Halon-based difluoromethylating approaches.

Bending and flexibility of kinetoplast DNA (1986)

We have evaluated the extent of bending at an anomalous locus in DNA restriction fragments from the kinetoplast body of Leishmania tarentolae using transient electric dichroism to measure the rate of rotational diffusion of DNA fragments in solution. We compare the rate of rotational diffusion of two fragments identical in sequence except for circular permutation, which places the bend near the center in one case and near one end of the molecule in the other. Hydrodynamic theory was used to conclude that the observed 20% difference in rotational relaxation times is a consequence of an overall average bending angle of 84 +/- 6 degrees between the end segments of the fragment that contains the bending locus near its center. If it is assumed that bending results from structural dislocations at the junctions between oligo(dA).oligo(dT) tracts and adjacent segments of B DNA, a bend angle of 9 +/- 0.5 degrees at each junction is required to explain the observations. The extent of bending is little affected by ionic conditions and is weakly dependent on temperature. Comparison of one of the anomalous fragments with an electrophoretically normal control fragment leads to the conclusion that they differ measurably in apparent stiffness, consistent with a significantly increased persistence length or contour length in the kinetoplast fragments.
Strong exciton–photon coupling in a low-Q all-metal mirror microcavity (2002)

We report the experimental observation of strong exciton–photon coupling in a planar microcavity composed of an organic semiconductor positioned between two metallic (silver) mirrors. Via transmission and reflectivity measurements, we observe a very large, room temperature Rabi splitting in excess of 300 meV. We show that the Rabi-splitting is enhanced in all-metal microcavities by a factor of more than 2 compared to an organic film positioned between a silver mirror and a dielectric mirror. This enhancement results from the significantly larger optical fields that are confined within all-metal microcavities.
Neuroprotective effect of<i>N</i>‐methyl‐<scp>d</scp>‐aspartate non‐competitive antagonists (arylcyclohexylamine derivatives) on human cultured spinal cord cells (1994)

The non-competitive N-methyl-D-aspartate antagonist cis-Pip/Me 1-[1-(2-thienyl)-2-methyl-cyclohexyl] piperidine (GK11) either in racemic(+/-) or (-) enantiomeric form has been investigated on survival of human fetal spinal cord cells in culture. The treated cultured cells were processed for immunocytochemical detection of GABA at different time intervals ranging from 3 to 27 weeks. The number of GABA-stained cells was found to be greater in the treated cultures than in the control ones. The qualitative and quantitative morphological features of both control and treated cells were analysed by computer-assisted methods which allowed us to individualize three different populations: (1) all control and treated small neuritic field neurons, (2) young control and old treated large neuritic field neurons and (3) old control neurons with large neuritic fields.
Selected-area liquid-phase epitaxy of iron garnet films applying local ion implantation of the substrate (1986)

Selected-area liquid-phase epitaxy of garnet films has been achieved through local substrate damage caused by ion implantation before film deposition. Thus, patterning with a geometrical resolution of a few microns of some micron-thick epitaxial garnet films is possible. Film patterns are defined by ‘‘perfect’’ epitaxial film regions grown on unimplanted substrate areas and defective film regions where the substrate has been implanted before film deposition. The films produced consist either of imperfect monocrystalline film areas, film areas resulting from island growth, or of substrate areas without overgrowth. Application of the method to the growth of epitaxial (Gd,Bi)3(Fe, Ga,Al)5 O12 films permits local magnetic switching of the magnetization direction confined to ‘‘perfect’’ film regions without switching of the adjacent imperfect film area.
Ranges of human mobility in Los Angeles and New York (2011)

The advent of ubiquitous, mobile, personal devices creates an unprecedented opportunity to improve our understanding of human movement. In this work, we study human mobility in Los Angeles and New York by analyzing anonymous records of approximate locations of cell phones belonging to residents of those cities. We examine two data sets gathered six months apart, each representing hundreds of thousands of people, containing hundreds of millions of location events, and spanning two months of activity. We present, compare, and validate the daily range of travel for people in these populations. Our findings include that human mobility changes with the seasons: both Angelenos and New Yorkers travel less in the winter, with New Yorkers showing a greater decrease in mobility during the cold months. We also show that text messaging activity does not by itself accurately characterize daily range, whereas voice calling alone suffices. Finally, we show that our methodology is accurate by comparing our results to ground truth obtained from volunteers.

Mirror-image pain in rat models of cancer-induced bone pain (2009)

Objective: To study the mirror-image pain phenomenon in rat models of cancer-induced bone pain(CIBP).Methods:Female SD rats(180～200 g body weight) were randomly divided into 3 groups(n=8): cancer group,sham-operated group and normal group.Paw withdraw threshold(PWT) of operated foot and non-operated foot of rats was measured by Von Frey Fiber every other day from 1 d before surgery to 15 d after surgery and compared among preoperation,postoperation and intergroup.At 15 d after surgery,the animals were first anesthetized with 25% of urethane at 0.6 ml/100 g,then 60 g Von Frey fiber were used to stimulate the non-operated hind paw for 2 min,followed by the perfusion with polychlorinated formaldehyde,isolation of the L5～L6 segment of the spinal cord and immunohistochemical stain after 2 h.Finally,the c-fos immuno-positive nerve cells in spinal dorsal horn were counted.Results:The PWT declined significantly after surgery in cancer group compared with the sham-operated group(P0.01) and normal group(P0.01),but no significant differences were observed between the sham-operated group and normal group(P0.05).After the right hind paw was stimulated,the number of c-fos immuno-positive nerve cells in spinal dorsal horn was significantly more in cancer group than those in other two groups(P0.01),but there was no significant difference between sham-operated and normal group.Conclusion:The mirror-image pain phenomenon does exist in CIBP models and the spinal cord has a greater response to noxious stimulation in non-operated paw.
Transparent Displays Utilizing Nanopatterned Quantum Dot Films (2018)

We report the realization of a transparent display using glass covered by a nanopatterned quantum dot (QD) film with good transmittance. The film was fabricated by nanoimprint lithography (NIL) and spin coating of colloidal QDs with specificexcitation maxima. The produced nanopatterned QD film was attached to transparent glass, enabling active image generation using a laser light source of a specific wavelength. Selective light emission was induced by strongly exciting the laser-exposed film surface, creating desired images, with color modulationenabled by controlling the QD layer (dozens of nanometers in size) via nanopatterning. The nanopatterned QD film used for image generation exhibits excellent transmittance (>80%), and can be used for transparent displays, with image realization in both bright and dark spaces. The fabricated displays have wide viewing anglesowing to their good light emission characteristics, and the fabrication through spin coating renders the fabrication process simple and applicable to large areas.

[Resistance and disintegration behavior of gastric juice-resistant drug products. 3. Pharmaceutical-technological and analytical studies of gastric juice-resistant commercial preparations]. (1987)

Enteric coated commercial dosage forms often do not correspond with acid resistance and disintegration requirements of the Ph. Eur. About 15-20% of 181 tested samples disintegrate during acid resistance test or do not disintegrate in buffer solution pH = 6.8. The percentage was extremely high amongst enteric coated pancreatin or cardiac glycosides (about 30%) preparations. Storage conditions and time influence acid resistance and disintegration time. 80% of 34 products coated with celluloseacetate phthalate, hydroxypropylmethylcellulose phthalate or polymethacrylic acid ester did not change disintegration time after 2 years storage at 20 degrees C. After storage at 40 degrees C the number decreased to 40%. After 5 years at 20 degrees C number of products which were not stable increased.
Picatinny Arsenal Cylinder Expansion Test and a Mathematical Examination of the Expanding Cylinder. (1995)

Abstract : To measure the effectiveness of an explosive, the cylinder expansion test is used. In order to decrease the cost and make performance testing available to smaller batch sizes in development, a reduced scale cylinder test as developed. To directly compare test results from different sized cylinders, a new Gurney equation was developed. Mathematical estimations were developed to examine the effects of the thinning walls in the cylinders to the measured performance.

Technical brief: subretinal injection and electroporation into adult mouse eyes. (2008)

A standardized surgical method and a fast distinct indicator of successful surgery were essential to establishing a gene delivery system based on subsequent electroporation. With the surgery better controlled, electroporation was adequate to transfect a substantial number of RPE cells in a defined position in the globe.
Chromium in the Canadian environment (1995)

The widening use of chromium and its compounds by local industries has led to a growing concern about the effects of chromium contamination on the Canadian environment. This report summarizes the data on Canadian sources and the concentrations of chromium in air, water, sediments, soil, terrestrial wildlife and aquatic biota. It reviews what little is currently known about the cycling of chromium in Canadian ecoystems, and the need for measuring Cr(III) and Cr(VI) rather than total Cr in the environmental media is emphasized. The potential effects of elevated levels of chromium on plants, soil microorganisms, wildlife, and aquatic biota are discussed. The human health effects are not covered. The conclusion is reached that chromium pollution has become a threat to Canadian ecosystems, especially at the local scale where the ambient chromium concentrations in some surface waters, sediments, and soils are now close to or above the toxicity threshold for a number of the more sensistive organisms.Key words: chromium pollution, chromium toxicity, chromium chemistry, chromium emission, bioaccumulation of chromium.
Importance of N-glycosylation positioning for cell-surface expression, targeting, affinity and quality control of the human AT1 receptor (2005)

GPCRs (G-protein-coupled receptors) are preferentially N-glycosylated on ECL2 (extracellular loop 2). We previously showed that N-glycosylation of ECL2 was crucial for cell-surface expression of the hAT1 receptor (human angiotensin II receptor subtype 1). Here, we ask whether positioning of the N-glycosylation sites within the various ECLs of the receptor is a vital determinant in the functional expression of hAT(1) receptor at the cell surface. Artificial N-glycosylation sequons (Asn-Xaa-Ser/Thr) were engineered into ECL1, ECL2 and ECL3. N-glycosylation of ECL1 caused a very significant decrease in affinity and cell surface expression of the resulting receptor. Shifting the position of the ECL2 glycosylation site by two residues led to the synthesis of a misfolded receptor which, nevertheless, was trafficked to the cell surface. The misfolded nature of this receptor is supported by an increased interaction with the chaperone HSP70 (heat-shock protein 70). Introduction of N-glycosylation motifs into ECL3 yielded mutant receptors with normal affinity, but low levels of cell surface expression caused by proteasomal degradation. This behaviour differed from that observed for the aglycosylated receptor, which accumulated in the endoplasmic reticulum. These results show how positioning of the N-glycosylation sites altered many properties of the AT1 receptor, such as targeting, folding, affinity, cell surface expression and quality control.
