Sublinear time algorithms in the theory of groups and semigroups (2010)

Sublinear time algorithms represent a new paradigm in computing, where an algorithm must give some sort of an answer after inspecting only a small portion of the input. The most typical situation where sublinear time algorithms are considered is property testing. There are several interesting contexts where one can test properties in sublinear time. A canonical example is graph colorability. To tell that a given graph is not $k$-colorable, it is often sufficient to inspect just one vertex with incident edges: if the degree of a vertex is greater than $k$, then the graph is not $k$-colorable. It is a challenging and interesting task to find algebraic properties that could be tested in sublinear time. In this paper, we address several algorithmic problems in the theory of groups and semigroups that may admit sublinear time solution, at least for “most” inputs.
Crash Testing and Evaluation of TxDOT Burn Ban Signs (2009)

Texas counties expressed a desire to the Texas Department of Transportation (TxDOT) to post advisory signs on the roadside to alert motorists when a burn ban is in effect. For obvious economic reasons, the preferred method of implementation is to append the burn ban notification signs to existing sign support structures already installed along Texas highways. In support of this request, TxDOT sponsored this project to evaluate the impact performance of a Texas slip base sign support system with a lightweight, composite burn ban sign appended to the support below the primary sign at a mounting height less than 7 ft. The impact performance of the burn ban sign support configurations was evaluated through full-scale crash testing. The crash testing was performed in accordance with the requirements of NCHRP Report 350. The configuration selected for testing incorporated a 24 in. × 24 in. × 0.080 in. thick aluminum confirmation sign mounted at a height of 7 ft, with the burn ban signs mounted below. Based on the satisfactory test results reported herein, the practice of appending a burn ban sign to an existing slip base sign support system is considered suitable for implementation.
Terahertz detection in a multi-gate high electron mobility transistor (2009)

We observe the THz response of a multi-gate high electron mobility transistor detector structure. These devices are fabricated from single heterostructure GaAs/AlGaAs material and feature three gates: a `source gate' adjacent to source terminal, a `drain gate' adjacent to drain terminal, and a narrow `barrier gate' biased to pinch-off that serves as a bolometric sensor. Bias dependent measurements of the responsivity indicate coupling to free carriers located in the non-metalized slots between gates. The absorbed terahertz radiation is sensed by the hot electron bolometer formed by the pinched off channel under the barrier gate.
Defects in electron-irradiated Ge studied by positron lifetime spectroscopy (1999)

The formation and annealing behavior of electron-irradiation induced defects in germanium were studied. The undoped Ge samples were irradiated at 4 K with an electron energy of 2 MeV. The fluence was varied between ${10}^{15}$ and ${10}^{19}{\mathrm{cm}}^{\mathrm{\ensuremath{-}}2}.$ Annealing experiments were performed from 90 K. Additional temperature-dependent positron lifetime measurements after different annealing stages were carried out to make a statement about charge states of defects and to the presence of shallow positron traps. Two main annealing stages were observed. The first between 150 and 250 K was attributed to the annealing of Frenkel pairs. The second annealing stage between 350 and 450 K was observed after irradiation with fluences above ${10}^{17}{\mathrm{cm}}^{\mathrm{\ensuremath{-}}2}$ and was assigned to annealing of a complex containing a vacancy and an impurity atom. Furthermore, shallow positron traps were detected after irradiation. This defect type anneals above 330 K in a wide-temperature range.
Active Content Popularity Learning and Caching Optimization With Hit Ratio Guarantees (2020)

Edge caching is an effective solution to reduce delivery latency and network congestion by bringing contents close to end-users. A deep understanding of content popularity and the principles underlying the content request sequence are required to effectively utilize the cache. Most existing works design caching policies based on global content requests with very limited consideration of individual content requests which reflect personal preferences. To enable the optimal caching strategy, in this article, we propose an Active learning (AL) approach to learn the content popularities and design an accurate content request prediction model. We model the content requests from user terminals as a demand matrix and then employ AL-based query-by-committee (QBC) matrix completion to predict future missing requests. The main principle of QBC is to query the most informative missing entries of the demand matrix. Based on the prediction provided by the QBC, we propose an adaptive optimization caching framework to learn popularities as fast as possible while guaranteeing an operational cache hit ratio requirement. The proposed framework is model-free, thus does not require any statistical knowledge about the underlying traffic demands. We consider both the fixed and time-varying nature of content popularities. The effectiveness of the proposed learning caching policies over the existing methods is demonstrated in terms of root mean square error, cache hit ratio, and cache size on a simulated dataset.

Characterization of fimbriae produced by enteropathogenic Escherichia coli (1993)

Enteropathogenic Escherichia coli (EPEC) express rope-like bundles of filaments, termed bundle-forming pili (BFP) (J. A. Girón, A. S. Y. Ho, and G. K. Schoolnik, Science 254:710-713, 1991). Expression of BFP is associated with localized adherence to HEp-2 cells and the presence of the EPEC adherence factor plasmid. In this study, we describe the identification of rod-like fimbriae and fibrillae expressed simultaneously on the bacterial surface of three prototype EPEC strains. Upon fimbrial extraction from EPEC B171 (O111:NM), three fimbrial subunits with masses of 16.5, 15.5, and 14.7 kDa were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Their N-terminal amino acid sequence showed homology with F9 and F7(2) fimbriae of uropathogenic E. coli and F1845 of diffuse-adhering E. coli, respectively. The mixture of fimbrial subunits (called FB171) exhibited mannose-resistant agglutination of human erythrocytes only, and this activity was not inhibited by alpha-D-Gal(1-4)-beta-Gal disaccharide or any other described receptor analogs for P, S, F, M, G, and Dr hemagglutinins of uropathogenic E. coli, which suggests a different receptor specificity. Hemagglutination was inhibited by extracellular matrix glycoproteins, i.e., collagen type IV, laminin, and fibronectin, and to a lesser extent by gangliosides, fetuin, and asialofetuin. Scanning electron microscopic studies performed on clusters of bacteria adhering to HEp-2 cells revealed the presence of structures resembling BFP and rod-like fimbriae linking bacteria to bacteria and bacteria to the eukaryotic cell membrane. We suggest a role of these surface appendages in the interaction of EPEC with eukaryotic cells as well as in the overall pathogenesis of intestinal disease caused by EPEC.
Spacially resolved heat flux measurements from HSDI engine over NEDC (C1305/047/2011) (2011)

A new design of heat flux sensor has been developed in order to allow investigations of the thermal state of IC engines. The sensor was designed to fit within the engine structure and to measure the radial heat flux in an 8 mm thick section of cast iron cylinder. The sensor was subject to a substantial calibration process prior to being installed longitudinally down cylinder two of a production diesel engine to investigate the thermal condition of the cylinders during NEDC tests. The heat flux calculated at the top of the bores was highly dynamic and closely followed engine power during transients. The observed heat flux is in the range up to 220 kW/m2 during the EUDC part of the drive cycle. The local heat transfer coefficients between metal and coolant are calculated and lay in the range 1.5 kW/m2K to 40 kW/m2K.
Typeface Emotion Analysis for Communication on Mobile Messengers (2016)

Nonverbal signals such as facial expressions and gestures cannot be conveyed by text messages on a mobile messenger. In this study, we investigate the potential use of typefaces for emotional representation by which people can feel nonverbal signals. We constructed a dataset of various typefaces and conducted a large-scale crowd-sourced user study to investigate the relationship between typefaces and emotional signals based on commonly used psychological emotion models. From the user study, we determined that several visual characteristics of typefaces have weak/strong emotional influences on viewers and verified that certain emotions and feelings can be conveyed on text messages.

UV generation with passively Q-switched picosecond microchip lasers (1995)

The generation of coherent UV radiation has typically required large, expensive laser systems. By quadrupling the output of a passively-Q-switched microchip laser,1 we have demonstrated 0.5-µJ UV pulses of 250-ps duration from a 3-cm-long×1-cm-diamfiter package. The device, illustrated in Fig. is pumped by a 1.2-W fiber-coupled diode laser and operates in a single-frequency, linearly polarized, diffraction-limited mode at pulse repetition rates up to 13 kHz over a temperature range of >70°C.

Insulin Induces Progressive Insulin Resistance in Cultured Rat Adipocytes: Sequential Effects at Receptor and Multiple Postreceptor Sites (1986)

We have examined the ability of insulin to regulate insulin action in primary cultured adipocytes, and found that insulin induces progressive insulin resistance in this target tissue. To assess effects at both receptor and postreceptor sites, we cultured cells in the absence (control) and presence of 100 ng/ml insulin, and, after various times, measured the dose response of insulin's ability to bind cell-surface receptors and stimulate 2-deoxyglucose transport. In control cells, insulin binding (0.2 ng/ml) was increased 10-13% due to an apparent increase in receptor affinity (6-24 h). A comparable increase in affinity was also observed in treated cells; however, concomitantly, insulin decreased the number of cell-surface receptors causing a slowly progressive net decrease in binding after a 6-10-h lag (maximal 30% at 24 h). When insulin action was assessed in control cells, the functional consequence of increased receptor binding was hypersensitization (i.e., increased insulin sensitivity) manifested by a leftward shift in the 2-deoxyglucose dose-response curve. On the other hand, in the treated cells, insulin produced insulin resistance initially by decreasing insulin sensitivity. The ED50 for insulin stimulation of glucose transport increased 84% from 0.31 to 0.57 ng/ml at 6 h without a net change in insulin binding; this was the result of a decrease in coupling efficiency between occupied receptors and the insulin effect. Receptor uncoupling progressively increased in severity, but before the full effect was reached insulin also caused a rapid decline in maximally stimulated glucose transport rates (between 6 and 10 h). This decrease in insulin responsiveness (maximal 52%) exacerbated overall insulin resistance, and was indicative of a postreceptor defect in the glucose transport system. Finally, insulin-induced receptor downregulation contributed, along with uncoupling, to a further decrease in insulin sensitivity, and constituted a more long-term regulatory mechanism. We also observed that insulin could regulate the basal glucose transport system by preventing a progressive rise in basal transport observed in control cells. In conclusion, primary cultured adipocytes can be used to study long-term regulation of insulin action. We found that insulin induces progressive insulin resistance with sequential effects at multiple sites in the insulin action pathway, including decreased coupling efficiency between occupied receptors and stimulated glucose transport, a postreceptor defect in insulin responsiveness of the glucose transport system, and receptor downregulation. These mechanisms may be relevant to the cellular defects in insulin action present i

Machine learning shows torsion angle preferences in left-handed and right-handed quadruplex DNAs (2022)

Left-handed G quadruplexes (LHG4) have been recently discovered as a new class of G quadruplexes. The biological functions of LHG4s are still unknown, but they share a striking resemblance to Z-DNA in their helicity and jagged phosphate backbone. To further understand structural features of the LHG4s that define their left handedness, we have employed human-interpretable machine-learning methods to classify right- and left-handed G4s purely based on torsional angle analysis. Our results reveal the importance of the α, β, δ, and χ angles in left-handed structuring across both Z-DNAs and LHG4s. Our analysis may serve as the first step to understanding the conditions of formation for LHG4s and their potential biological relevance.
Simultaneous nonunique decoding is rate-optimal (2012)

It is shown that simultaneous nonunique decoding is rate-optimal for the general K-sender, L-receiver discrete memoryless interference channel when encoding is restricted to randomly generated codebooks, superposition coding, and time sharing. This result implies that the Han-Kobayashi inner bound for the two-user-pair interference channel cannot be improved simply by using a better decoder such as the maximum likelihood decoder. It also generalizes and extends previous results by Baccelli, El Gamal, and Tse on Gaussian interference channels with point-to-point Gaussian random codebooks and shows that the Cover-van der Meulen inner bound with no common auxiliary random variable on the capacity region of the broadcast channel can be improved to include the superposition coding inner bound simply by using simultaneous nonunique decoding. The key to proving the main result is to show that after a maximal set of messages has been recovered, the remaining signal at each receiver is distributed essentially independently and identically.
Nucleotide Sequence of a Root-Specific Transcript Encoding a Germin-Like Protein from the Halophyte Mesembryanthemum crystallinum (1992)

Following environmental stresses that impair water avail- ability, transcription of a number of genes is induced in the facultative halophyte Mesembryanthemum crystallinum (com- mon ice plant) in aerial parts of the plants (2,(8)(9)(10).Identified products of induced transcripts enable the plant to cope with such stresses, either long term by the induction of the CAM pathway (2, 3) or in a shorter time frame by the expression of enzymes leading to the biosynthesis of osmotically balanc- ing substances (10).Although the expression of these genes and induction of the corresponding biochemical pathways provide stress protection or stress amelioration, we think that major defense mechanisms against stresses that affect the plant's water status are mounted by the root system in the ice plant (Table I).This statement is based on the observation that salt stress leads to a global change in the expression of genes in the root system-a response that is much broader than the changes observed (8, 10) in aerial parts of the plants.By differential screening of a cDNA library established for mRNAs isolated from roots after 6 h of salt stress, several hundred of either up-regulated or down-regulated mRNAs were indicated (C.B.Michalowski, E.F.McElwain, personal communication).Partial sequencing of a number of these cDNAs suggested pu- tative functions of some cDNAs (for which homologies in the sequence data bases were indicated) in signal transduction pathways, in transporting substances or ions across mem- branes, or in functions that had been implied before to be affected by water balance in plants (4, 7).An example for the latter function is the sequence of a cDNA for a germinlike protein (Fig. 1).Germin is one of a few proteins whose synthesis is induced within hours after the imbibition of dry wheat seeds (4, 6, 7).Recently, polypeptides that are immu- nologically related and show amino terminal amino acid homology to wheat germins have been found to increase in roots of salt-stressed barley plants (5).Both the predicted ice plant protein and wheat proteins share homology with pro- teins from the slime mold Physarum polycephalum, sphaerulins (1), which increase in response to environmental stress conditions that lead to encystment.
Generalized volterra series model for highly nonlinear optical interconnects, circuits and devices (2007)

The ever increasing speed and scaling of the CMOS technology have enabled the implementation of very complex systems within a single IC. The inadequacy of electronics to efficiently meet the rising interconnect requirements have created a bottleneck at the interconnect level. The unique properties of optics as a data propagation medium have thus created a window of opportunity for the penetration of optics into mainstream electronic circuits. The development of optical interconnect models that can easily be incorporated into standard circuit simulation environments can help optics seize this opportunity. Although the optical link component modeling has been extensively researched, these models usually require explicit knowledge of numerous proprietary device parameters. 
To this end, we in this dissertation propose a Generalized Volterra Series (GVS) modeling method that provides a comprehensive representation of both small-signal and large-signal end-to-end behavior of optical interconnects. The GVS model enables system level signal integrity and timing analysis of electrical systems employing optical interconnects through a polynomial based representation, which is estimated through non-sophisticated sinusoidal and DC measurements that have traditionally been used in electronics. 
The encapsulation of the optical link components into a single behavioral construct eliminates the need for circuit designers to gain expertise in the field of optics. The proposed approach generates a black-box model for the end-to-end behavior of the optical link to enable the representation of the system response without explicit knowledge of its implementation. Therefore, by alleviating the dependence on implementation details, the GVS model offers a unique advantage over more detailed analytical models that rely on numerous manufacturing parameters, which are proprietary and in many cases hard to obtain. While the GVS model has been introduced in this thesis in the context of end-to-end modeling of optical interconnects, the domain independent nature of the proposed black-box model makes it an invaluable tool for the modeling of any system, circuit or device.
NHC–Cu-Catalyzed Addition of Propargylboron Reagents to Phosphinoylimines. Enantioselective Synthesis of Trimethylsilyl-Substituted Homoallenylamides and Application to the Synthesis of S-(−)-Cyclooroidin (2014)

A catalytic method for the efficient and enantioselective addition of a 1-trimethylsilyl-substituted allene moiety to phosphinoylimines is presented. Transformations are promoted by 5.0 mol % of a copper complex of an N-heterocyclic carbene in the presence of a propargylboron reagent that can be readily prepared in multigram quantities. Within 10 min of reaction, products are obtained in up to 91% yield, 98% allene (vs propargyl) selectivity, and 98:2 enantiomeric ratio. An assortment of aldimines serve as suitable substrates. The phosphinoyl and silyl groups can be removed efficiently and orthogonally. The silylallene moiety may be transformed to versatile derivatives that are difficult to access via nonsilylated allenes. The special features and utility of the approach are highlighted through a succinct enantioselective synthesis of marine alkaloid S-(-)-cyclooroidin.
