SEARCH FOR PATTERNS IN COMPRESSED TIME SERIES (2002)

We describe a technique for fast compression of time series, indexing of compressed series, and retrieval of series similar to a given pattern. The compression procedure identifies "important" points of a series and discards the other points. We use the important points not only for compression, but also for indexing a database of time series. Experiments show the effectiveness of this technique for indexing of stock prices, weather data and electroencephalograms.

Infield logistics planning for crop-harvesting operations (2009)

Crop-harvesting operations are typically carried out with combine harvesters. The harvested product is transferred to one or more tractors every time the combine harvester's storage capacity is reached. The efficiency of the process can be significantly improved by computing optimal routes and interactions for the harvest vehicles in the field. Furthermore, an automated method for generating itineraries for the harvest vehicles facilitates the planning for autonomous agricultural vehicles. The infield logistics problem is formulated as an integer linear programming vehicle routing problem with additional turn penalty constraints, but, because of the high number of decision variables, it is not possible to solve cases of realistic field size. The solution time of the infield logistics problem is considerably reduced by reformulating it as a modified minimum-cost network flow problem. This specific structure allows the exact solution of intermediate-size planning problems in a much shorter time period. The result of solving the infield logistics problem with the proposed modelling approaches is a set of itineraries (‘tours’), covering the entire field. Each ‘tour’ is characterized by the combine harvester's start and end points and the positions where the combine harvester needs to be unloaded. The planning models minimize non-productivity (i.e. the time when a combine harvester travels in a field without harvesting). The results indicate that coordination between combine harvesters and tractors is also improved.
Breast Cancer Genes: Therapeutic Strategies (1997)

Although effective treatments for breast cancer predated the identification of causative molecular defects in humans, it is widely hoped that an understanding and/or manipulation of the key genetic events will lead to even more effective therapies or even cures. Powerful methods of positional cloning and gene identification have identified the breast cancer genes, BRCA1 and BRCA2, which together are responsible for the majority of cases of hereditary breast and ovarian cancer. Although the BRCA1 gene is rarely mutated in sporadic breast or ovarian cancer, levels of BRCA1 mRNA and protein are markedly decreased in the majority of sporadic cases of cancer. This suggests that hereditary and sporadic breast cancer share common genetic themes and that treatments aimed at increasing levels of BRCA1 or BRCA2 may be useful for both hereditary and sporadic cancers. We have demonstrated that gene transfer of wild-type BRCA1 inhibits the growth of sporadic breast and ovarian cancer cells and suppresses growth of established breast and ovarian tumor models in nude mice. Mutant BRCA1 genes do not inhibit growth or suppress tumor, providing additional evidence that BRCA1 is a tumor-suppressor gene. Strategies designed to increase BRCA1 expression or development of BRCA1-mimetic agents may be ultimately useful as therapeutic approaches.
Optical Probing of the Electronic Interaction between Graphene and Hexagonal Boron Nitride (2013)

Even weak van der Waals (vdW) adhesion between two-dimensional solids may perturb their various materials properties owing to their low dimensionality. Although the electronic structure of graphene has been predicted to be modified by the vdW interaction with other materials, its optical characterization has not been successful. In this report, we demonstrate that Raman spectroscopy can be utilized to detect a few percent decrease in the Fermi velocity (v(F)) of graphene caused by the vdW interaction with underlying hexagonal boron nitride (hBN). Our study also establishes Raman spectroscopic analysis which enables separation of the effects by the vdW interaction from those by mechanical strain or extra charge carriers. The analysis reveals that spectral features of graphene on hBN are mainly affected by change in v(F) and mechanical strain but not by charge doping, unlike graphene supported on SiO₂ substrates. Graphene on hBN was also found to be less susceptible to thermally induced hole doping.

Microcirculatory blood flow as a tool to select ICU patients eligible for fluid therapy (2012)

These data add to the understanding that noninvasive assessment of microvascular blood flow may help to identify patients eligible for fluid therapy, and to evaluate its effect.
Compliant Surfaces: Introduction (1980)

It is noted that the essence of the compliant surface question is whether or not wall motion can provide a decrease in skin friction for either transitional or turbulent flows. This wall motion is capable of being externally excited or flow driven, with varying amounts of fluid motion-wall motion phasing (depending primarily upon wall structural configuration and damping). It is concluded that current research has eroded still further the experimental data base which indicates drag reduction on compliant surfaces under turbulent boundary layers in air. The need for further clarification and research is stressed for the small wavelength liquid case.
Pervasive Power: A Radioisotope-Powered Piezoelectric Generator (2005)

A long-lasting radioisotope micropower generator for self-powered sensor microsystems promises to make pervasive computing systems more reliable. Its higher energy conversion efficiency enables microsystems with small amounts of radioactivity to realize sensor and basic computation operations. The goal is to achieve power sources that operate over a wide temperature range and for extended time periods with high reliability. To reach this goal, researchers have investigated technologies for miniature micropower applications and developed radioisotope power generators. We've created a power source employing radioactive thin films and piezoelectric unimorphs, using a nonthermal energy conversion cycle that enables much higher energy conversion efficiency.

A Detection and Offense Mechanism to Defend Against Application Layer DDoS Attacks (2007)

Application layer DDoS attacks, which are legitimate in packets and protocols, gradually become a pressing problem for commerce, politics and military. We build an attack model and characterize layer-7 attacks into three classes: session flooding attacks, request flooding attacks and asymmetric attacks. We proposed a mechanism named as DOW (defense and offense wall), which defends against layer-7 attacks using combination of detection technology and currency technology. An anomaly dete-ction method based on K-means clustering is introduced to detect and filter request flooding attacks and asymmetric attacks. To defend against session-flooding attacks, we propose an encouragement model that uses client's session rate as currency. Detection model drops suspicious sessions, while currency model encourages more legitimate sessions. By collaboration of these two models, normal clients could gain higher service rate and lower delay of response time.

Viscoelastic Properties of Polystyrene Solutions (1965)

Quartz crystals resonant in the fundamental torsional mode at frequencies of 40 and 73 kc/sec have been used to measure the viscoelastic properties of solutions of polystyrene in toluene, methylethylketone, and cyclohexane. A monodisperse polystyrene sample of molecular weight 2.39×105 was employed. The results have been compared with those of Harrison, Lamb, and Matheson (1964) for dilute solutions in toluene of a number of polystyrene samples of different molecular weight. In toluene, it is found that 25% of the contribution of the polymer to the viscosity of the solution is not able to take part in viscoelastic relaxation, and that the dynamic viscosity at high frequencies (the “Einstein viscosity”) is greater than the solvent viscosity. Under these conditions, the viscoelastic behavior of all time solutions of toluene of polystyrene samples of different molecular weights agrees with the predictions of the Rouse theory. From time value obtained for the Einstein viscosity of the solutions, it is shown that the radius of time equivalent hydrodynamic sphere is approximately proportional to the square root of the molecular weight of the polymer molecule. The viscoelastic behavior of the solution in methylethylketone is intermediate between the predictions of the Zimm and Rouse theories.
Capacitively Loaded, Inductively Coupled Fed Loop Antenna With an Omnidirectional Radiation Pattern for UHF RFID Tags (2013)

A capacitively loaded, inductively coupled fed loop antenna with an omnidirectional radiation pattern for UHF radio frequency identification (RFID) tags is proposed. The inductively coupled feed structure is beneficial for conjugate impedance matching. The loaded capacitors in the radiating and feeding loops allow for easy control of the resonant frequency and the antenna reactance, respectively. The omnidirectional radiation pattern on the horizontal plane makes the proposed tag insensitive to be mounted on different target objects. With a small size of 43 <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$\,\times\,$</tex> </formula> 43 mm <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$^2$</tex> </formula> , the measured maximum reading range of the prototype is 9.5 m with a total transmitted power of 4.0 W effective isotropic radiated power (EIRP).
First Demonstration of Virtual Transport Network Services With Multi-layer Protection Schemes over Flexi-grid Optical Networks (2015)

Based on the virtualization technique in optical networks, virtual transport network services (VTNS) has been introduced as a new kind of service in transport networks. With VTNS, transport providers are able to provide their customers entire virtual topologies instead of traditional end-to-end connections. This letter analyzes the new characteristics (i.e., multiple operators, diversified services) aiming at the survivability problem in virtualized optical transport networks, and proposes three novel protection schemes for VTNS against the new features. For the first time, VTNS with the proposed protection schemes are demonstrated on the flexi-grid optical networks testbed with commercial optical transport equipments. Additionally, the performances of the proposed protection schemes have been evaluated via simulations.
Influence of substrate resistivity on the degradation of silicon solar cell performance due to crystal defects (1988)

The dependencies of minority carrier diffusion length and solar cell parameters on dislocation density were experimentally determined for silicon substrates of different resistivities. These data show that an increase in the substrate carrier concentration reduces the influence of dislocations on the carrier recombination and the cell parameters. Furthermore, the increase in V/sub oc/ and the decrease in J/sub sc/ that accompany a decrease in the substrate resistivity depend on the substrate dislocation density. This effect makes the optimum substrate resistivity a function of the average dislocation density of the substrate. These results dictate the choice of the substrate resistivity for obtaining optimum performance of solar cells fabricated on single-crystal or large-grain polycrystalline silicon of known average dislocation density.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effects of Bisphenol S on the Structures and Activities of Trypsin and Pepsin (2014)

The effects of bisphenol S on the structures and activities of trypsin and pepsin were investigated by various methods like UV-visible absorbance, fluorescence, circular dichroism, and molecular docking. The secondary and tertiary structures of trypsin and pepsin were altered by bisphenol S binding, which resulted in the loosening of the skeletons of trypsin and pepsin. In addition, bisphenol S induced microenvironmental changes around tyrosine and tryptophan residues of trypsin and pepsin. The activity experimental results showed that the activity of pepsin decreases obviously with the increasing concentration of BPS, while the activity of trypsin does not change remarkably. The binding and thermodynamic parameters obtained by molecular docking and fluorescence spectroscopy showed that the bindings of bisphenol S to trypsin and pepsin were spontaneous processes and hydrogen bonding and hydrophobic interactions played a vital role in stabilizing the bisphenol S-trypsin and bisphenol S-pepsin complexes. The binding constants (K(A)) of bisphenol S with trypsin were 7.42 × 10(4) (298 K) and 5.91 × 10(4) L/mol (310 K), and those of pepsin were 5.78 × 10(4) (298 K) and 4.44 × 10(4) L/mol (310 K). Moreover, there was one main kind of binding site for bisphenol S on trypsin or pepsin.
Asymmetrical bisintercalators as potential antitumor agents (1988)

Ditercalinium and its analogues are dimeric molecules made up of two identical 7H-pyrido[4,3-c]carbazole rings linked by symmetrical linking chains. These dimers elicit antitumor properties through a new mechanism of action. Recently, a relationship was found between their antitumor properties and their cytotoxic effect on the polA Escherichia coli mutant strain, suggesting that 7H-pyrido[4,3-c]carbazole dimers might induce a DNA deformation that could be recognized by the E. coli SOS repair system. Thus, the role of symmetry in ditercalinium analogues for their DNA binding, antitumor properties, and bacterial toxicity is investigated in the present study, by introducing asymmetric parameters in their structures. Dimers were either synthesized with an asymmetrical rigid linking chain or made up of two chemically different chromophores, i.e., acridine and 7H-pyrido[4,3-c]carbazole. The asymmetrical dimers remain able to bisintercalate into DNA with high affinities, but a dramatic loss in their antitumor potency is observed. On the other hand, these asymmetrical dimers are cytotoxic for polA E. coli mutants, like their symmetrical analogues. These results show that the symmetry plays a crucial role for the antitumor potency in the 7H-pyrido[4,3-c]carbazole dimers series.
Control of release rate of bleomycin from polylactic acid microspheres by additives. (1985)

Polylactic acid (PLA) microspheres containing bleomycin were prepared by a solventevaporation process. The release rate of bleomycin from PLA microspheres was very small. The release profiles of the drug from microspheres prepared by using L-and DL-isomers and PLA of different molecular weights did not differ significantly for up to 120 h. The release rate of the drug could be greatly enhanced by incorporating fatty acid esters as additives in the microspheres. It was found that the release rate of the drug could be controlled by using different additives and by adjusting the amount of the additive. Scanning electron microscopic observations suggested that the additive was uniformly distributed in the microspheres as small droplets. The enhanced release rate of the drug in the presence of the additives can be attributed to the highly porous structure of the PLA matrix through which the drug is released by diffusion.

Several different enterovirus serotypes can be associated with prediabetic autoimmune episodes and onset of overt IDDM (1998)

In a prospective multicentre study described previously on prediabetic events in siblings of index cases with insulin-dependent diabetes mellitus, 31 children developed clinical diabetes during the observation period and 51 children seroconverted for islet cell antibodies or insulin autoantibodies. By using nonserotype specific EIA and RIA, it has shown recently that enterovirus infections in both groups were frequently associated with increases of islet cell antibody and/or insulin autoantibody titres. Serum specimens sequentially collected from 12 children during the prediabetic period were still available and were then tested for serotype-specific neutralizing antibodies. Plaque-neutralization assays were carried out for coxsackievirus A9, coxsackievirus B types 1 to 6, and echovirus types 1 and 11. An unequivocal monotypic increase in neutralizing antibodies was observed on seven occasions in six children, on one occasion with coxsackievirus A9, one with coxsackievirus B1, two with coxsackievirus B2, two with coxsackievirus B3, and one with coxsackievirus B5. In four patients, the infection was associated temporally with increases in the levels of islet cell antibodies, insulin autoantibodies and/or antibodies to glutamic acid decarboxylase, and in three other patients, it coincided with the clinical onset of insulin-dependent diabetes mellitus. These results suggest that the association of enterovirus infections with insulin-dependent diabetes mellitus is not restricted to serotype 4 of coxsackie B viruses suspected previously, but that several different serotypes might play a role in the pathogenesis of the disease.
A new visualization paradigm for multispectral imagery and data fusion (2003)

We present a new formalism for the treatment and understanding of multispectral images and multisensor imagery based on first order contrast information. Although little attention has been paid to the utility of multispectral contrast, we develop a theory for multispectral contrast that enables us to produce an optimal grayscale visualization of the first order contrast of an image with an arbitrary number of bands. We demonstrate how our technique can reveal significantly more interpretive information to an image analyst, who can use it in a number of image understanding algorithms. Existing grayscale visualization strategies are reviewed and a discussion is given as to why our algorithm is optimal and outperforms them. A variety of experimental results are presented.
