Glenohumeral Arthrodesis After Failed Prosthetic Shoulder Arthroplasty (2009)

Treatment of a failed prosthetic shoulder arthroplasty with concomitant extensive glenohumeral bone loss and soft-tissue deficiencies is extremely challenging. The results of this study suggest that glenohumeral arthrodesis can yield satisfactory clinical outcomes. However, both the patient and the surgeon should be aware of the complex nature of this surgery and the frequent need for additional surgical procedures to obtain fusion.
High-gain, high-frequency AlGaAs/GaAs graded band-gap base bipolar transistors with a Be diffusion setback layer in the base (1985)

AlGaAs/GaAs heterojunction bipolar transistors (HBT’s) with graded band-gap bases were fabricated from computer-controlled molecular beam epitaxy layers. It was found that the use of an undoped setback layer of 200–500 Å to offset Be diffusion in the emitter resulted in significant current gain increases. Maximum current gains of 1150 for a base width of 0.18 μm were obtained which are the highest yet reported for graded base HBT’s. Zn diffusion was used to contact the base and provides a low base contact resistance. Microwave s-parameter measurements yielded fT=5 GHz and fmax=2.5 GHz. Large signal pulse measurements resulted in rise times of τr∼150 ps and pulsed collector currents of Ic&gt;100 mA which is useful for high current laser drivers.
Duvall-Structure-Based Adaptive Beamforming Method for Cancellation of Coherent and Incoherent Interferences (2008)

CZZ (Concatenated Zigzag) Code is a class of fast encodable LDPC codes. In the case that LDPC codes including CZZ codes have short length, short cycles seriously affect the code performance. In this paper, we construct CZZ codes using various degree-2 polynomial interleavers which eliminate cycles of length 4 and through simulation, compare the performance of these CZZ codes and turbo codes in many different fading channels. Especially, quasi-static fading channel, block fading channel, uncorrelated fading channel, and correlated fading channel are considered. Since CZZ codes show similar performance as turbo codes, they can be used in the next generation wireless communication systems.
La colère, source d'insécurité routière ? In Sécurité des déplacements, protection des usagers et de l'environnement - Maîtrise des risques et prévention Tome 1 (2015)

La colere est une emotion negative definie par un fort arousal (i.e., elle provoque un etat d'activations psychologique et physiologique intenses). C'est egalement une emotion frequemment ressentie en conduite (Sullman, 2006; Underwood, Chapman, Wright, & Crundall, 1999). Une des raisons a cela est qu'elle peut etre causee par un evenement sans rapport avec la conduite, mais aussi par un evenement provenant directement de la tâche de conduite (e.g., Jeon, Walker, & Yim, 2014). La colere serait a l'origine de plusieurs modifications comportementales et attentionnelles chez les conducteurs.
The Approximation with Rational Functions of Prescribed Magnitude and Phase Characteristics (1952)

A successive-approximations method is applied to the selection of network functions having desired magnitude and phase variation with frequency. The first approxination, the first set of pole and zero locations, can be selected on the basis of known solutions to similar problems or through use of a set of curves. In succeeding approximations the pole and zero locations are adjusted to decrease the deviation of the earlier approximations from the desired characteristics. The process adjusts the magnitude and phase characteristics simultaneously. Its flexibility permits accommodation of practical constraints not possible with other methods.
Absolute Rate Constants for Iminyl Radical Reactions (1997)

The kinetics of cyclization of the 2-methyl-6,6-diphenyl-5-hexeniminyl radical (3) were measured by laser flash photolysis methods from 0 to 50 degrees C, and the kinetics of trapping of radical 3 by thiophenol and p-chlorothiophenol were determined between 4 and 83 degrees C by indirect methods using the unimolecular rate constants as the basis values. Radical 3 cyclizes with a rate constant of 2.2 x 10(6) s(-)(1) at 25 degrees C and reacts with thiophenol and p-chlorothiophenol at this temperature with rate constants of 0.6 and 1.4 x 10(7) M(-)(1) s(-)(1), respectively. Bu(3)SnH reacted with 3 too slowly to prevent nearly complete cyclization, but a crude rate constant for the trapping reaction was estimated. The cyclization and trapping reactions of iminyl radical 3 are slower than the corresponding reactions of alkyl radicals.
Synthesis of 4- and 6-Azaindoles via the Fischer Reaction (2009)

Contrary to the common idea that Fischer indole cyclization often cannot be effectively applied to the synthesis of the corresponding azaindoles, we show that this approach can be actually very efficient for the formation of 4- and 6-azaindoles bearing an electron-donating group on the starting pyridylhydrazines. Two 4-azaindole natural product analogues were synthesized in a few steps and very good overall yields.
Optical fiber transmission of 2 kW cw YAG laser and its practical application to welding (1990)

The YAG laser has an excellent characteristic that makes beam transmission with optical fibers. In addition, the oscillator of the 2 kW class has recently been developed, and so its applications are changing largely from conventional fine material processing. The authors have adopted the YAG laser welding that uses optical fibers favorable to application to narrow, complicated areas. First, the authors have analyzed the beam intensity distribution near the focusing point using ray tracing method, and manufactured the compact condensing optical lens systems, and metal mirrors which have high reflectivity and durability that can be inserted in the tubes of about 16 mm I.D. to weld them. And also have developed the beam transmission system that can transmit beam for a long distance of about 200 m using small diameter optical fibers. In addition, with these systems the welding conditions to get about 2 mm penetration for stable welding has been obtained and applied YAG laser welding of steam generator tubes in practical nuclear power plants.
An Experimental Study on Switching Threshold for Adaptive Modulation in Broadband FWA Systems (2006)

A number of wireless systems have recently adopted an adaptive modulation scheme to improve frequency efficiency. Unlike mobile systems, FWA (fixed wireless access) systems including IEEE 802.16 systems used for MAN (metropolitan area network) are allowed to use quasi-millimeter and millimeter bands, but those are vulnerable to rain attenuation. Adaptive modulation scheme is effective in those systems to improve the availability of wireless links. A 26 GHz-band broadband FWA system with a five-level (1024 QAM to BPSK) adaptive modulation scheme was proposed and developed by the authors for field experiments. This paper introduces field experimental results concerning switching thresholds for adaptive modulation controls using the developed FWA system. The numerical results reveal that conventional ideas, in which identical switching thresholds in terms of BER (bit error rate) apply to all modulation methods and switching thresholds maximizing Layer-2 throughput, can neither obtain the maximum TCP (transmission control protocol) throughput nor satisfy the upper limit of the UDP (user datagram protocol) packet loss rate.
Annotation of Putative Circadian Rhythm-Associated Genes in <i>Diaphorina citri</i> (Hemiptera : Liviidae) (2021)

Abstract The circadian rhythm is a process involving multiple genes that generates an internal molecular clock, allowing organisms to anticipate environmental conditions produced by the earth’s rotation on its axis. This report presents the results of the manual curation of twenty-seven genes likely associated with circadian rhythm in the genome of Diaphorina citri , the Asian citrus psyllid. This insect acts as the vector of the bacterial pathogen Candidatus Liberibacter asiaticus (CLas), the causal agent of citrus greening disease (Huanglongbing). This disease is the most severe detriment to citrus industries and has drastically decreased crop yields worldwide. Based on the genes identified in the psyllid genome, namely cry1 and cry2, D. citri likely possesses a circadian model similar to that of the lepidopteran butterfly, Danaus plexippus . Manual annotation of these genes will allow future molecular therapeutics to be developed that can disrupt the psyllid biology.
Cathodic Protection of Bronze Propellers for Copper Nickel Surfaced Ships (1981)

The finite element method was employed to determine an acceptance method for cathodically protecting bronze propellers on a Cu-Ni surfaced slip. Experiments conducted in a water tunnel were used to establish the need for cathodic protection for this case and to determine the needed data. The analysis of the propeller geometry was accomplished by using a highly twisted wedge shape and periodic boundary conditions. A number of individual anode locations and multi-anode protection systems were investigated to determine the configuration with the least power dissipation. A method for establishing current requirements for each of the three anodes chosen was devised to ensure adequate protection for all of the propeller surfaces. These results were extended to cover a range of propeller diameters.
On the performance of cooperative wireless networks under interference conditions (2007)

User cooperation can be employed to provide transmit diversity in wireless networks . In this paper we analyze the error performance of coded cooperative diversity with multiple cooperating users over Nakagami fading channels under interference conditions. We derive the end-to-end bit error probability of coded cooperation (averaged over all cooperation scenarios). Results show that allowing more cooperating users improves the performance of the network under low loads, where two cooperating users suffice for highly-loaded networks. Furthermore, the gains obtained by increasing the number of cooperating users decreases with increasing the network load.
Isolation and characterization of temperature-sensitive mutants of the<i>Staphylococcus aureus dnaC</i>gene (2002)

A protein encoded by the Staphylococcus aureus dnaC gene has 44% and 58% homology with Escherichia coli DnaB and Bacillus subtilis DnaC replicative DNA helicases, respectively. We identified five mutant strains whose temperature-sensitive colony formation phenotypes were complemented by the dnaC gene. DNA replication in these mutants has a fast-stop phenotype, indicating that the S. aureus dnaC gene encodes the replicative DNA helicase required for the elongation step. These mutants were also sensitive to UV irradiation, suggesting that the dnaC gene is involved in DNA repair. The number of viable mutant cells decreased at a non-permissive temperature, suggesting that S. aureus DnaC helicase is a promising target for antibiotics providing bactericidal effects.
Induction of Neutralizing Antibodies to Transmissible Gastroenteritis Virus by Anti-Idiotypic Antibodies (1989)

The potential of anti-idiotypic antibodies (anti-ids) as immunogens against transmissible gastroenteritis virus (TGEV) was tested in a heterologous system. A month-old pig was immunized with a neutralizing murine monoclonal antibody (MAb, 5A5) of the IgG2a isotype, specific for the E2 glycoprotein of TGEV. The anti-ids were isolated from the serum of the immunized pig by affinity chromatography, initially on a 5A5-Sepharose column, followed by repeated adsorption on a mouse IgG2a column. The swine anti-ids thus obtained bound to the MAb 5A5 (the idiotype), but not to MAbs of the same isotype IgG2a but of different idiotypes. The anti-ids also inhibited the binding of 5A5 to TGEV in a concentration-dependent manner. Mice immunized with the anti-ids produced antibodies to TGEV. These antibodies, neutralized TGEV in vitro and inhibited the binding of 5A5 to TGEV.
Phospholipid crystalline clusters induced by adsorption of novel amphiphilic triblock copolymers to monolayers (2008)

The molecular arrangement in mixed monolayers resulting from the adsorption of the novel water soluble amphiphilic triblock copolymers of poly(glycerol monomethacrylate) and poly(propylene oxide) (PGMA-b-PPO-b-PGMA) to phospholipid monolayer films has been investigated at the air-water interface. All measurements were performed at an intermediate initial surface pressure (10.2 mN m−1) of the acyl chain perdeuterated phospholipids dipalmitoylphosphatidylcholine (DPPC-d62) or dimyristoylphosphatidylcholine (DMPC-d54), and at a bulk (PGMA14)2-PPO34 concentration of 8 µM, which is well below its critical micelle concentration. Brewster Angle Microscopy (BAM) images show that in spite of the different physical state of the DPPC-d62 compared to the DMPC-d54 monolayers, at longer equilibration times an optically homogenous mixed monolayer is obtained in both cases. The conformation of the lipid acyl chains was monitored, simultaneously with BAM imaging, through the frequency of the perdeuterated methylene symmetric νs(CD2) stretching band by infrared reflection absorption spectroscopy (IRRAS). It shows that the conformational order brought about by the copolymer adsorption is preserved even after the domains formed initially have completely disappeared and a homogeneous lipid-polymer mixed monolayer has been obtained. Based on these results it is concluded that a mixed monolayer consisting of clusters of lipid molecules, having a substantial conformational order of their lipid acyl chains (i.e., a larger population of trans conformers) and sizes in the mesoscopic to nanoscopic range, surrounded by a network of block copolymer chains is formed.
Optimal treatment and current situation in reperfusion after thrombolysis for acute myocardial infarction (2002)

Acute myocardial infarction is the leading cause of death in the industrialized world and the paramount goal is establishing early, complete, and sustained reperfusion at the myocardial tissue level. For hospitals without the capacity to perform emergent percutaneous coronary intervention, fibrinolytic therapy plays a critical role although it is limited by a 67% success rate. Despite promising pilot studies, reduced-dose fibrinolytic therapy with glycoprotein IIb/IIIa therapy (GUSTO-V) and full-dose fibrinolytic therapy with enoxaparin (ASSENT-3) or bivalirudin (HERO-2) provide only marginally improved clinical outcomes. Adjunctive in-hospital and secondary preventive measures should include an aspirin, a beta-blocker, an ACE inhibitor, and a statin, based on the Heart Protection Study, unless contraindicated. Patients should be risk stratified, participate in a cardiac rehabilitation program, cease smoking tobacco, and have an intracardiac defibrillator (ICD) implanted if their LV systolic function is < or = 30% at one month based on the MADIT-2 trial.
Three-carrier spin blockade and coupling in bilayer graphene double quantum dots (2022)

The spin degree of freedom is crucial for the understanding of any condensed matter system. Knowledge of spin-mixing mechanisms is not only essential for successful control and manipulation of spin-qubits, but also uncovers fundamental properties of investigated devices and material. For electrostatically-defined bilayer graphene quantum dots, in which recent studies report spin-relaxation times T1 up to 50ms with strong magnetic field dependence, we study spin-blockade phenomena at charge configuration $(1,2)\leftrightarrow(0,3)$. We examine the dependence of the spin-blockade leakage current on interdot tunnel coupling and on the magnitude and orientation of externally applied magnetic field. In out-of-plane magnetic field, the observed zero-field current peak could arise from finite-temperature co-tunneling with the leads; though involvement of additional spin- and valley-mixing mechanisms are necessary for explaining the persistent sharp side peaks observed. In in-plane magnetic field, we observe a zero-field current dip, attributed to the competition between the spin Zeeman effect and the Kane-Mele spin-orbit interaction. Details of the line shape of this current dip however, suggest additional underlying mechanisms are at play.
Diagnostic Value of Immature Neutrophils (Bands) in the Cerebrospinal Fluid of Children With Cerebrospinal Fluid Pleocytosis (2009)

In this multicenter study, neither the presence nor quantity of CSF bands independently predicted bacterial meningitis among children with CSF pleocytosis.
A COMBINED RESEARCH AND CURRICULUM PROGRAM IN SIGNAL PROCESSING FOR COMMUNICATIONS (2005)

This paper describes a combined curriculum and research program that aims to provide scientific and investigative experiences to undergraduate (UG) students by immersing them into Electrical Engineering communications and signal processing research. Our objective is to raise the interest of undergraduates in thesis-oriented research and hence attract them to graduate education programs or prepare them for research careers in the industry. The innovation includes the development of research modules that expose UG students to signal processing for communications (SP-COM) research. These modules are taken by students across the Electrical Engineering SP-COM curriculum. Four interrelated modules are first injected in early junior-level “Signal and systems” and “Random signal analysis” courses and then in senior-level “Digital signal processing” and “Communications systems” courses. In addition, a new senior-level elective UG course entitled “Introduction to signal processing for communications research,” is being developed for Fall 2005. Evaluation and assessment procedures are in place to evaluate the modules and measure the success of our objectives.
Secret message capacity of a line network (2014)

We investigate the problem of information theoretically secure communication in a line network with erasure channels and state feedback. We consider a spectrum of cases for the private randomness that intermediate nodes can generate, ranging from having intermediate nodes generate unlimited private randomness, to having intermediate nodes generate no private randomness, and all cases in between. We characterize the secret message capacity when either only one of the channels is eavesdropped or all of the channels are eavesdropped, and we develop polynomial time algorithms that achieve these capacities. We also give an outer bound for the case where an arbitrary number of channels is eavesdropped. Our work is the first to characterize the secrecy capacity of a network of arbitrary size, with imperfect channels and feedback. As a side result, we derive the secret key and secret message capacity of an one-hop network, when the source has limited randomness.
Effects of LAs&rsquo; Strategic Bidding on Wholesale Electricity Market Equilibrium (2017)

This paper proposes a game-theoretic framework for quantifying effects of strategic bidding behavior of load aggregators (LAs) on wholesale electricity market equilibrium. The independent system operator (ISO) employs double-sided auction design to settle transactions in the wholesale electricity market. Generating companies (GENCOs) and LAs submit their bids to the ISO in the economic model of supply function equilibrium. Under the smart grid paradigm, a LA participates in the electricity market on behalf of end-consumers to minimize their total payment for purchasing electricity. In this paper, bi-level programming (BLP) method is employed to determine optimal bidding strategy of self-interested market participants. In the upper level, the profit of intended market participant is maximized and in the lower level, the ISO clears the market via a bid-based security constrained economic dispatch (SCED). Also, competition of GENCOs and LAs is modeled as a non-cooperative game. To examine the effects of strategic bidding behavior of LAs on market equilibrium, the proposed model is applied to the IEEE 9-bus and the IEEE 30-bus test systems. According to numerical results, to allow the LAs to behave strategically along with the GENCOs makes the former better off and the latter worse off, while the net effect of this on total social welfare turns out to be case-contingent.

Sodium dodecyl sulfate‐capillary electrophoresis of proteins in a sieving matrix utilizing two‐spectral channel laser‐induced fluorescence detection (1998)

We report a method for protein labeling, separation by capillary electrophoresis in a polymer sieving matrix, and detection by laser-induced fluorescence. Different dyes are used to label standard and sample proteins. A two-spectral channel detector resolves fluorescence from the sample and standards. Comparison of the migration time of the sample and standards permits the precise determination of molecular weight, irrespective of variations in run-to-run migration times.
Search for a low-mass neutral Higgs boson with suppressed couplings to fermions using events with multiphoton final states (2016)

A search for a Higgs boson with suppressed couplings to fermions, ${h}_{f}$, assumed to be the neutral, lower-mass partner of the Higgs boson discovered at the Large Hadron Collider, is reported. Such a Higgs boson could exist in extensions of the standard model with two Higgs doublets, and could be produced via $p\overline{p}\ensuremath{\rightarrow}{H}^{\ifmmode\pm\else\textpm\fi{}}{h}_{f}\ensuremath{\rightarrow}{W}^{*}{h}_{f}{h}_{f}\ensuremath{\rightarrow}4\ensuremath{\gamma}+X$, where ${H}^{\ifmmode\pm\else\textpm\fi{}}$ is a charged Higgs boson. This analysis uses all events with at least three photons in the final state from proton-antiproton collisions at a center-of-mass energy of 1.96 TeV collected by the Collider Detector at Fermilab, corresponding to an integrated luminosity of $9.2\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. No evidence of a signal is observed in the data. Values of Higgs-boson masses between 10 and $100\text{ }\text{ }\mathrm{GeV}/{c}^{2}$ are excluded at 95% Bayesian credibility.
Focal childhood‐onset, action induced primary hip dystonia treated with pallidal deep brain stimulation (2008)

Focal proximal lower limb dystonias are rare. Unlike the adult form, focal lower limb dystonias in children usually become generalized. The condition is often unrecognized and the patient often receives orthopedic or psychiatric treatment for years before the diagnosis eventually made. Previously reported cases of isolated lower limb dystonias have been managed nonsurgically. We present a case of a childhood-onset action-induced primary hip dystonia that has remained focal even in adulthood and which responded successfully to pallidal deep brain stimulation. Additionally, our results suggest that neurons representing the leg lie within the most ventral aspect of the globus pallidus interna.
