Hybrid Finite-Element Analysis of Leaky Surface Acoustic Waves in Periodic Waveguides (1996)

A numerical approach based on the hybrid finite-element method (HFEM) is developed for the analysis of leaky surface acoustic wave (LSAW) propagation along periodic waveguides. Only a region corresponding to one period of the waveguide is discretized, and the dispersion relation between complex propagation constants and frequencies around a stop band and the standing-wave distributions at these frequencies are calculated. Using the hybrid variational principle, the region to which HFEM is applied is divided into elements with suitable interpolation functions; the inhomogeneous region including electrodes is divided into conventional quadratic elements of the serendipity class, and the remaining homogeneous substrate region is replaced with a hybrid element with specialized interpolation functions which are derived from modal expansions and satisfy the radiation condition of LSAWs. In this method, all the effects of piezoelectric perturbation, mechanical perturbation, energy storage due to nonradiated bulk waves, and radiation loss of LSAWs are automatically taken into account. Using this method, aluminum strip gratings on an Al/ST- X quartz or a 36° Y – X LiTaO 3 substrate are analyzed, and the validity of this method is confirmed.
Application of multiuser coding to random access protocols (1988)

The usefulness of multiuser coding for throughput enhancement in various random-access protocols with (0, 1, e) feedback is examined. A scheme is proposed in which the user population is divided into two or more classes and multiuser coding is used in such a manner that all collisions among at most one-user-per-class are resolved by virtue of the multiuser code. For ALOHA, tree, and interval-splitting random-access protocols, significant improvements in throughput are demonstrated when multiuser coding techniques are used.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Estimating Velocity Fields on a Freeway From Low-Resolution Videos (2006)

An algorithm to estimate velocity fields from low-resolution video recordings is presented. The algorithm does not attempt to identify and track individual vehicles, nor does it attempt to estimate derivatives of the field of pixel intensities. Rather, a frame is compressed by obtaining an intensity profile in each lane along the direction of traffic flow. The speed estimate is then computed by searching for a best matching profile in a frame at earlier and later times. It is shown that the estimate is equivalent to a weighted median of velocities of vehicles. Because the algorithm does not need high-quality images, it is directly applicable to a compressed format digital video stream, such as .mpeg, from conventional traffic video cameras. The procedure is illustrated using a 15-min-long Video Home System recording to obtain speed estimates on a 1-mi stretch of highway I-80 in Berkeley, CA
Key caching mechanism for AAA over mobile IP (2006)

Abstract —RFC 2977 proposes the Authentication, Authorization,Accounting (AAA) framework architecture for mobile IP toprotect signaling messages from eavesdropping by maliciousattackers. The AAA server in the home network (i.e., AAAH)generates and distributes session keys to Mobile Node (MN), Foreign Agent (FA), and Home Agent (HA), which is known asthe authentication procedure. The procedure for session keydistribution introduces extra signaling overhead in the mobileIP network, which is not considered in RFC 2977. To resolvethis issue, this paper proposes a key caching algorithm namedAKC. With AKC, the MN can be authenticated locally withoutinvolving the AAAH. The simulation experiments are conductedto investigate the performance of the AKC algorithm. I. I NTRODUCTION With the rapid development of the mobile networkingtechnologies, mobile computing over Internet has become oneof the major research directions. Users with mobile equipmentenjoy Internet services through wireless networks anywhereand any time. To efﬁciently route the packets for the mobileusers in the Internet, the working group,
Encoding User as More Than the Sum of Their Parts (2017)

Neural networks and word embeddings are powerful tools to capture latent factors. These tools can provide effective measures of similarities between users or items in the context of sparse data. We propose a novel approach that relies on neural networks and word embeddings to the problem of matching a learner looking for mentoring, and a tutor that is willing to provide this mentoring. Tutors and learners can issue multiple offers/requests on different topics. The approach matches over the whole array of topics specified by learners and tutors. Its performance for tutor-learner matching is compared with the state of the art. It yields similar results in terms of precision, but improves the recall.
Myotonic disorders: A review article. (2016)

The myotonic disorders are a heterogeneous group of genetically determined diseases that are unified by the presence of myotonia, which is defined as failure of muscle relaxation after activation. The presentation of these disorders can range from asymptomatic electrical myotonia, as seen in some forms of myotonia congenita (MC), to severe disability with muscle weakness, cardiac conduction defects, and other systemic features as in myotonic dystrophy type I (DM1). In this review, we describe the clinical features and pathophysiology of the different myotonic disorders, their laboratory and electrophysiologic findings and briefly review the currently available treatments.

Effects of Marker Selection and Mix Time on the Coefficient of Variation (Mix Uniformity) of Broiler Feed (2007)

An experiment was conducted evaluating several markers to determine mix uniformity. Treatment diet was a corn-soybean meal-based diet formulated for broiler chicks fed from 0 to 17 d posthatch. Dietary nutrients or tracers evaluated included the following: 1) dl-Met (99%), 2) l-Lys-HCl (78%), 3) CP, 4) mixing salt (chloride ion), 5) P, 6) Mn, 7) Fe particles (#40 Red, count), 8) Fe particles (#40 Red, absorbance), 9) Fe particles (RF-Blue Lake), 10) roxarsone, and 11) semduramicin. All minor and microingredients were individually hand-weighed and added to the mixer to insure accuracy and were added at the same location for all treatments. Diets were mixed using a double ribbon mixer for 3 different mix times (0.5, 2.5, and 5.0 min). Overall, from 0.5 to 5.0 min, all markers evaluated showed a numerical reduction in percentage of CV. Crude protein and P should not be considered as markers, because many different components in the batch of feed contribute some level of CP or P, and results can be confounding. dl-Methionine (99%) and l-Lys-HCl (78%) were the only markers that statistically reduced over time and had a CV < 10% (23.86 to 9.47% and 19.75 to 8.70%, respectively). These data suggest that mixer uniformity results can be influenced by the particular marker that is chosen for mixer uniformity analysis.
Solution Processed Top‐Gate <i>n</i>‐Channel Transistors and Complementary Circuits on Plastics Operating in Ambient Conditions (2008)

Top-gate n-TFTs and CMOS circuits on plastic substrates based on solution-processed n- and p-channel semiconductors and polymeric dielectrics have been fabricated. These unencapsulated devices exhibit good performance characteristics in ambient.
Relative gene-silencing efficiencies of small interfering RNAs targeting sense and antisense transcripts from the same genetic locus (2004)

Short interfering RNAs (siRNAs) directed against different regions of genes display marked variation in their potency in mediating mRNA degradation. Various factors have been proposed to affect the efficacy of siRNA. We explored some of the factors by evaluating in cultured human cells 28 randomly selected siRNAs targeting the GPR39 and MGC29643 transcripts derived from the same genetic locus but transcribed in opposite directions. Twenty of the 24 siRNAs targeting the overlapping regions of the transcripts simultaneously reduced the levels of both transcripts. Single nucleotide changes in either of the siRNA strands significantly reduced the gene-silencing efficiency of the siRNA on targeted sense transcript without affecting the antisense transcript. Overall, we observed a greater gene-silencing efficiency on the MGC29643 transcript than on the GPR39 transcript in HeLa cells. Since MGC29643 transcript is more abundant than the GPR39 transcript [0.24 versus 0.008% relative to 100% for glyceraldehyde-3-phosphate dehydrogenase (GAPDH)], the results suggest that the abundance of the mRNA affects the efficiency of silencing. Two additional observations supported this hypothesis. First, GAPDH whose intracellular level is the highest of the three was the most efficiently silenced. Second, a reversal of gene-silencing efficiency was observed in U-138 MG cells in which the relative abundance of the GPR39 and MGC29643 transcripts is also reversed. Our study suggests that low-abundant transcripts are less susceptible to siRNA-mediated degradation than medium- and high-abundant transcripts.
Novel Blocking Human IgG Directed against the Pentapeptide Repeat Motifs of <i>Neisseria meningitidis</i> Lip/H.8 and Laz Lipoproteins (2011)

Ab-initiated, complement-dependent killing contributes to host defenses against invasive meningococcal disease. Sera from nonimmunized individuals vary widely in their bactericidal activity against group B meningococci. We show that IgG isolated from select individuals can block killing of group B meningococci by human sera that are otherwise bactericidal. This IgG also reduced the bactericidal efficacy of Abs directed against the group B meningococcal protein vaccine candidates factor H-binding protein currently undergoing clinical trials and Neisserial surface protein A. Immunoblots revealed that the blocking IgG was directed against a meningococcal Ag called H.8. Killing of meningococci in reactions containing bactericidal mAbs and human blocking Abs was restored when binding of blocking Ab to meningococci was inhibited using either synthetic peptides corresponding to H.8 or a nonblocking mAb against H.8. Furthermore, genetic deletion of H.8 from target organisms abrogated blocking. The Fc region of the blocking IgG was required for blocking because F(ab')(2) fragments were ineffective. Blocking required IgG glycosylation because deglycosylation with peptide:N-glycanase eliminated blocking. C4b deposition mediated by an anti-factor H-binding protein mAb was reduced by intact blocking IgG, but not by peptide:N-glycanase-treated blocking IgG, suggesting that blocking resulted from inhibition of classical pathway of complement. In conclusion, we have identified H.8 as a meningococcal target for novel blocking Abs in human serum. Such blocking Abs may reduce the efficacy of select antigroup B meningococcal protein vaccines. We also propose that outer membrane vesicle-containing meningococcal vaccines may be more efficacious if purged of subversive immunogens such as H.8.
Lithium nitrides as sustainable energy materials (2008)

Lithium nitride is an exceptional yet simple compound with remarkable properties that can be tuned with judicious chemical modifications. A unique structure coupled with high ionic mobility present both a fundamental model and an advanced material for energy applications, involving either storage of charge (lithium) or storage of hydrogen. In the former case, and as an electrode material, the system can be modified to increase defects and the number of charge carriers, both ionic and electronic. In so doing, one can create anodes of high reversible capacity. In the latter context, tailoring structure, microstructure, and composition has profound effects on both the amount of hydrogen one can store in the solid state and the rate at which this process (uptake and release) can be achieved.
Novel aluminum–BODIPY dyads: intriguing dual-emission via photoinduced energy transfer (2016)

Three novel BODIPY-based heterodinuclear complexes, [salen(3,5-(t)Bu)2Al-(OC6H4-BODIPY)] (6), [salen(3,5-(t)Bu)2Al-(OC6F2H2-BODIPY)] (7), and [(mq)2Al-(OC6H4-BODIPY)] (8) (salen = N,N'-bis(salicylidene)ethylenediamine, BODIPY = 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene, and mq = methyl-8-quinolinolato) were prepared and characterized by multinuclear NMR spectroscopy. The specific structures of 6-8 were also determined by single crystal X-ray analysis. In particular, the salen-based heterodinuclear complexes 6 and 7 exhibited higher thermal stability (Td5 = 309 and 306 °C, respectively) than that of the closely related mononuclear aluminum or BODIPY compounds, except for 8. The UV/vis absorption and PL spectra for 6 and 7 indicated a significant photoinduced energy transfer from the aluminum-salen moiety to the BODIPY group in an intramolecular manner. Theoretical calculations revealed independent transition states of the aluminum-salen moiety or the BODIPY group in the Al(III)-BODIPY dyads, further supporting these experimental results.
Inertia identification for speed control of PMSM servo motor (2011)

In most servo motor drive applications, speed control is affected not only by disturbance torque but also by mechanical parameters such as inertia and friction coefficient. This paper presents a new technique for the inertia and friction identification which are based on adaptive identification. The strategy has been simulated and implemented in a drive system. The results demonstrate the high performance of the scheme.
Epidemiological approach to the control of horse strongyles (1985)

An investigation of the spring rise in strongyle egg output of grazing horses on two commercial horse farms in northern USA in 1981 and 1982 revealed two distinct spring and summer rises in faecal egg counts, with peaks in May and August/September. There was a marked rise in the concentration of infective larvae on pasture two to four weeks after the peaks in egg output, so that grazing horses were at serious risk from June onwards and pasture larval counts on one farm did not fall to low levels until June of the following year. The spring and summer rises in faecal egg counts appeared to be seasonal in nature, to be derived largely from worms developing from previously ingested larvae, rather than from newly ingested larvae, and to be unrelated to the date of foaling. An epidemiological approach to strongyle control based on prophylactic treatments in the spring successfully eliminated the spring rise in egg output but was inadequate to control the summer rise or subsequent escalation of pasture infectivity in September. It was, nevertheless, superior to a conventional treatment programme at eight week intervals, using the same drug, pyrantel pamoate. Prophylactic spring/summer treatments proved to be much more effective. Both pyrantel pamoate at four week intervals and ivermectin at eight week intervals kept faecal egg counts at low levels during spring and summer. As few as two ivermectin treatments (11 May, 6 July) resulted in a sixfold reduction in pasture larval counts on 9 November and 3 January for the treated group (8872, 8416 stage three larvae [L3]/kg) compared to the control group (52,824, 50,984 L3/kg).(ABSTRACT TRUNCATED AT 250 WORDS)
Surface Morphology of Thermal, Furnace and Pyrolytic Carbon Blacks by Nitrogen Adsorption - Relation to the Electrical Conductivity (2002)

Abstract The surface morphology of various carbon blacks was studied by low-pressure nitrogen adsorption. The shape of their low-pressure nitrogen isotherm depends on the concentration of surface defects. This defect concentration on the surface is different for thermal blacks, even for those of the same grade. Different surface morphologies were also observed for carbon blacks obtained by pyrolysis of truck tires. The concentration of defects increased with pyrolysis pressure. For the various furnace blacks, however, similar surface morphologies were observed. The electrical conductivity of thermal and pyrolytic carbon blacks decreases with increasing defect concentration. However, in spite of a similar surface morphology, different conductivities were observed for furnace blacks. The carbon black surface morphology is therefore not a determining factor for the electrical conductivity. Furthermore, the graphitic character of the carbon black surface was studied by secondary ion mass spectroscopy (SIMS). For thermal, furnace and pyrolytic carbon blacks, the conductivity increased with increasing graphitic character of the carbon black surface, thus underlining the importance of this parameter.
Synthesis and Evaluation of Neuroprotective α,β-Unsaturated Aldehyde Scavenger Histidyl-Containing Analogues of Carnosine (2005)

The synthesis, scavenging activity, and cytoprotective profiles of histidyl-containing carnosine analogues bearing hydrazide or 1,2-diol moieties is reported. Some compounds have demonstrated higher aldehyde-sequestering efficiency than carnosine and were also efficient in protecting SH-SY5Y neuroblastoma cells and rat hippocampal neurons from 4-hydroxy-trans-2,3-nonenal (HNE)-mediated death. The cytoprotective efficacy of these compounds suggests their potential use as therapeutic agents for disorders that involve excessive membrane lipids peroxidation and HNE-mediated neuronal toxicity.
A review of the repair of reinforced concrete beams (2006)

This paper reviews works on repairing of deteriorated reinforced concrete beams. Every structural element should be designed for a particular type of loading as well as for adopting of different types of environment. However many civil structural elements, like reinforced concrete beams are often required to be repaired to restore the structural integrity and to protect the reinforcement from sever weathering condition. Recently repairing is gradually increasing with the increase of age of concrete structures. In some instances it may be more economical to accept the need for maintenance or repair at suitable intervals than to attempt to build a structure that will be maintenance-free under severe conditions for a long period. Several types of materials and techniques are available for repairing of exiting deteriorated reinforced concrete beams. In this paper, causes of deterioration of concrete as well as repairing by using cement grout, mortar, concrete, sprayed concrete or shotcrete, epoxy, ferrocement with mortar, Fiber Reinforced Polymer (FRP) Sprayed Fiber Reinforced Polymer (SFRP) and the techniques of applying of these materials and also some resin based materials for bonding agent between interface of old concrete and newconcrete are reported.The advantages anddisadvantages ofthesematerials,causes ofdebondingbetweenconcretesubstrateandnewconcreteapplied on substrate and preventive measures are also discussed.

Charge Carriers in Few-Layer Graphene Films (2006)

The nature of the charge carriers in 2D few-layer graphites (FLGs) has been recently questioned by transport measurements [K. S. Novoselov, Science 306, 666 (2004)10.1126/science.1102896] and a strong ambipolar electric field effect has been revealed. Our density functional calculations demonstrate that the electronic band dispersion near the Fermi level, and consequently the nature of the charge carriers, is highly sensitive to the number of layers and the stacking geometry. We show that the experimentally observed ambipolar transport is only possible for an FLG with a Bernal-like stacking pattern, whereas simple-carrier or semiconducting behavior is predicted for other geometries.
Measuring Password Guessability for an Entire University (CMU-CyLab-13-013) (2018)

Despite considerable research on passwords, empirical studies of password strength have been limited by lack of access to plaintext passwords, small data sets, and password sets specifically collected for a research study or from low-value accounts. Properties of passwords used for high-value accounts thus remain poorly understood. We fill this gap by studying the single-sign-on passwords used by over 25,000 faculty, staff, and students at a research university with a complex password policy. Key aspects of our contributions rest on our (indirect) access to plaintext passwords. We describe our data collection methodology, particularly the many precautions we took to minimize risks to users. We then analyze how guessable the collected passwords would be during an offline attack by subjecting them to a state-of-the-art password cracking algorithm. We discover significant correlations between a number of demographic and behavioral factors and password strength. For example, we find that users associated with the computer science school make passwords more than 1.8 times as strong as those of users associated with the business school. In addition, we find that stronger passwords are correlated with a higher rate of errors entering them. We also compare the guessability and other characteristics of the passwords we analyzed to sets previously collected in controlled experiments or leaked from low-value accounts. We find more consistent similarities between the university passwords and passwords collected for research studies under similar composition policies than we do between the university passwords and subsets of passwords leaked from low-value accounts that happen to comply with the same policies.
Effect of Antimicrobial Interventions on the Oral Microbiota Associated with Early Childhood Caries. (2016)
