Hydrogen Cyanamide Induces Budbreak of Peaches and Nectarines Following Inadequate Chilling (1990)

Hydrogen cyanamide (Dormex) treatments were applied to 17 insufficiently chilled peach and nectarine cultivars ≈6 weeks after normal budbreak. Treatment effectively induced vegetative budbreak and reduced shoot dieback. The responses to Dormex treatments were linear, with the 2% rate being more effective than the 0 and 1% rates in most cases.
Spontaneous Immunity against Bcl-xL in Cancer Patients (2005)

It is well-established that peptide epitopes derived from human tumor-associated Ags can be recognized by CTL in the context of the MHC molecule. However, the vast majority of Ags described are not vital for survival and growth of the tumor cells, and immunoselection of Ag-loss variants during immunotherapy has been demonstrated in several cases. Malfunctions in death pathways observed in human cancers are often due to overexpression of antiapoptotic proteins in the Bcl-2 protein family, i.e., Bcl-2, Mcl-1, and Bcl-xL. These antiapoptotic proteins are implicated in cancer development, tumor progression, and drug resistance. The general overexpression of the antiapoptotic members of the Bcl-2 family in cancer and the fact that down-regulation or loss of expression of these proteins as a means of immune escape would impair sustained tumor growth makes them very attractive targets for anticancer immunotherapy. Recently, we identified spontaneous T cell responses against Bcl-2- and Mcl-1-derived peptides in patients suffering from cancers of different origin. In this study, we demonstrate that Bcl-xL is a target for T cell recognition in cancer patients. Thus, we describe spontaneous HLA-A2-restricted cytotoxic T cell responses against peptide epitopes derived from Bcl-xL by means of ELISPOT and flow cytometry stainings, whereas no responses were detected against any of the Bcl-xL epitopes in any healthy controls. Moreover, Bcl-xL-specific T cells are cytotoxic against HLA-matched cancer cells of different origin. Thus, cellular immune responses against apoptosis inhibitors like the Bcl-2 family proteins appear to represent a general feature in cancer.
A Few-Shot Learning Based Approach to IoT Traffic Classification (2021)

IoT traffic classification is an important step in network management. Efficient and accurate IoT traffic classification helps Internet Service Providers provide high-quality services to network users. At present, popular IoT traffic classification methods are using traditional machine learning or deep learning algorithm, which relies on a large amount of labeled traffic to construct the traffic-level fingerprinting. However, it is worth noting that some classes of IoT devices only generate limited labeled traffic when they are working, and this limited labeled traffic is insufficient for the aforementioned classification methods. In this letter, we propose Festic, a few-shot learning based approach to IoT traffic classification. Festic can accurately classify IoT traffic under conditions of insufficient labeled traffic. We evaluate Festic on two publicly available datasets, and the experimental results show that Festic has excellent classification accuracy and outperforms the state-of-the-art traffic classification methods.
ICC++—a C++ dialect for high performance parallel computing (1996)

ICC++ is a new concurrent C++ dialect which supports a single source code for sequential and parallel program versions, the construction of concurrent data abstractions, convenient expression of irregular and fine-grained concurrency, and high performance implementation. ICC++ programs are annotated with potential concurrency, facilitating both sharing source with sequential programs and automatic grain size tuning for efficient execution. Concurrency control is at the object level; each object ensures the consistency of its own state. This consistency can be extended over larger data abstractions. Finally, ICC++ integrates arrays into the object system and the concurrency model. In short, ICC++ addresses concurrency and its relation to abstractions --- whether they are implemented by single objects, several objects, or object collections. The design of the language, its rationale, and where to find implementations are all described.
Nano-plasmonic antennas in the near infrared regime (2012)

Plasmonic nano-antennas constitute a central research topic in current science and engineering with an enormous variety of potential applications. Here we review the recent progress in the niche of plasmonic nano-antennas operating in the near infrared part of the spectrum which is important for a variety of applications. Tuning of the resonance into the near infrared regime is emphasized in the perspectives of fabrication, measurement, modeling, and analytical treatments, concentrating on the vast recent achievements in these areas.
Optical modulation characteristics of a twin-guide laser by an electric field (1991)

The characteristics for a twin-guide (TG) laser modulated by a reverse bias are studied for the first time. The extinction ratio and the wavelength shift are 20 dB with only 1 V bias and −0.4 nm, respectively. Further, the characteristics of a TG modulator itself (that has the same structure as the TG laser) are measured under a driving current lower than the threshold. The possibility of integrating a TG modulator with a tunable twin-guide (TTG) laser is presented.

The integrin needle in the stromal haystack: emerging role in corneal physiology and pathology (2014)

Several studies have established the role of activated corneal keratocytes in the fibrosis of the cornea. However, the role of keratocytes in maintaining the structural integrity of a normal cornea is less appreciated. We focus on the probable functions of integrins in the eye and of the importance of integrin-mediated keratocyte interactions with stromal matrix in the maintenance of corneal integrity. We point out that further understanding of how keratocytes interact with their matrix could establish a novel direction in preventing corneal pathology including loss of structural integrity as in keratoconus or as in fibrosis of the corneal stroma.
Copyright protection of vector map using digital watermarking in the spatial domain (2011)

This paper proposes a robust blind watermarking scheme for 2D-vector data used in Geographical Information Systems (GIS). The proposed method embeds two types of watermarks that complement each other into the vector data. It preserves the fidelity of the vector data using an intersection test. Simulation results show that our method is resistant to common attacks such as translations, scaling, rotation, generalization, cropping, adding objects, and noise attacks. The proposed method also maintains the topology of the vector data.
The appearance of the UmuD'C protein complex in <i>Escherichia coli</i> switches repair from homologous recombination to SOS mutagenesis (1993)

The process of SOS mutagenesis in Escherichia coli requires (i) the replisome enzymes, (ii) RecA protein, and (iii) the formation of the UmuD'C protein complex which appears to help the replisome to resume DNA synthesis across a lesion. We found that the UmuD'C complex is an antagonist of RecA-mediated recombination. Homologous recombination in an Hfr x F- cross decreased as a function of the UmuD'C cell concentration; this effect was challenged by increasing RecA concentration. Recombination of a u.v.-damaged F-lac with the lac gene of an F- recipient was reduced by increasing the UmuD'C concentration while lac mutagenesis increased, showing an inverse relationship between recombination and SOS mutagenesis. We explain our data with the following model. The kinetics of appearance of the UmuD'C complex after DNA damage is slow, reaching a maximum after an hour. Within that period, excision and recombinational repair have had time to occur. When the UmuD'C concentration relative to the number of residual RecA filaments, not resolved by recombinational repair, becomes high enough, UmuD'C proteins provide a processive factor for the replisome to help replication bypass and repel the standing RecA filament. Thus, at a high enough concentration, the UmuD'C complex will switch repair from recombination to SOS mutagenesis.

Subsea thermoelectric generators. 1- 10-watt peltier effect prototypes - a step towards autonomous electrical control units at subsea wellheads (1994)

Offshore oil production activities require the operation of underwater hydraulic or electric equipment. The high cost of acquisition and installation of umbilical cables to supply power is leading to the development of independently powered cableless equipment, connected to the surface by the transmission and reception of control signals through the water. As a first step toward these autonomous wellhead control systems, the authors designed and successfully tested in laboratory conditions a thermoelectric generator able to supply at least 10 watts of electric power, extracting it from the temperature difference between the oil and the surrounding water. Hydraulic pumps and pressure accumulators, control electronics, and valve actuators for wellhead control units are all technically solved problems, even for seafloors as deep as 1,000 meters. However, an autonomous underwater wellhead control unit can only be conceived if an energy source is available at the seafloor. The development of a reliable and compact power source is indeed a fundamental step towards autonomous wet Christmas tree valve actuators.
Broadband &#x0022;focus-free&#x0022; terahertz imaging using axicons (2014)

We report the use of axicons to achieve broadband "focus-free" imaging in transmission and reflection at terahertz wavelengths. We demonstrate how the use of a broadband terahertz source improves the resolution of the imaging system, and how by using time-of-flight data the axial position and dimension of objects within the large depth of field of the axicon (160 mm) could be determined.
Chronic allergic contact dermatitis promotes skin cancer (2014)

Allergic contact dermatitis (ACD) is well recognized as an adverse event associated with implantable medical devices that contain allergenic materials like nickel; however, other cutaneous consequences of chronic exposure to allergens in implanted devices are not well understood. Here, we present a clinical case of Marjolin's ulcer, an invasive squamous cell carcinoma (SCC) that developed in response to chronic ACD caused by an orthopedic implant. We used a standard murine model of contact hypersensitivity to determine whether chronic ACD promotes skin carcinogenesis. Chronic application of 1-fluoro-2,4-dinitrobenzene (DNFB) to carcinogen-treated skin led to the development of papillomas and aggressive SCC. DNFB-driven chronic ACD was marked by type 2 inflammation, which mediated skin carcinogenesis, as mice unable to mount an inflammatory response were less likely to develop skin tumors. Importantly, we found similar tumor-promoting inflammation surrounding the SCC in our patient. Our findings demonstrate that chronic ACD caused by constant exposure to an allergen can promote tumorigenesis at skin sites with preexisting cancer-initiated cells. Moreover, our results suggest that patients with implantable devices placed in close proximity to the skin should be monitored for ACD and highlight the importance of patch testing prior to the placement of such devices.
The long-term efficacy of currently used dental implants: a review and proposed criteria of success. (1986)

Criteria for the evaluation of dental implant success are proposed. These criteria are applied in an assessment of the long-term efficacy of currently used dental implants including the subperiosteal implant, the vitreous carbon implant, the blade-vent implant, the single-crystal sapphire implant, the Tubingen implant, the TCP-implant, the TPS-screw, the ITI hollow-cylinder implant, the IMZ dental implant, the Core-Vent titanium alloy implant, the transosteal mandibular staple bone plate, and the Branemark osseointegrated titanium implant. An attempt has been made to standardize the basis for comments on each type of implant.
Effect of Catalysis on the Stability of Metallic Nanoparticles:  Suzuki Reaction Catalyzed by PVP-Palladium Nanoparticles (2003)

The small size of nanoparticles makes them attractive in catalysis due to their large surface-to-volume ratio. However, being small raises questions about their stability in the harsh chemical environment in which these nanoparticles find themselves during their catalytic function. In the present work, we studied the Suzuki reaction between phenylboronic acid and iodobenzene catalyzed by PVP-Pd nanoparticles to investigate the effect of catalysis, recycling, and the different individual chemicals on the stability and catalytic activity of the nanoparticles during this harsh reaction. The stability of the nanoparticles to the different perturbations is assessed using TEM, and the changes in the catalytic activity are assessed using HPLC analysis of the product yield. It was found that the process of refluxing the nanoparticles for 12 h during the Suzuki catalytic reaction increases the average size and the width of the distribution of the nanoparticles. This was attributed to Ostwald ripening in which the small nanoparticles dissolve to form larger nanoparticles. The kinetics of the change in the nanoparticle size during the 12 h period show that the nanoparticles increase in size during the beginning of the reaction and level off toward the end of the first cycle. When the nanoparticles are recycled for the second cycle, the average size decreases. This could be due to the larger nanoparticles aggregating and precipitating out of solution. This process could also explain the observed loss of the catalytic efficiency of the nanoparticles during the second cycle. It is also found that the addition of biphenyl to the reaction mixture results in it poisoning the active sites and giving rise to a low product yield. The addition of excess PVP stabilizer to the reaction mixture seems to lead to the stability of the nanoparticle surface and size, perhaps due to the inhibition of the Ostwald ripening process. This also decreases the catalytic efficiency of the nanoparticles due to capping of the nanoparticle surface. The addition of phenylboronic acid is found to lead to the stability of the size distribution as it binds to the particle surface through the O(-) of the OH group and acts as a stabilizer. Iodobenzene is found to have no effect and thus probably does not bind strongly to the surface during the catalytic process. These two results might have an implication on the catalytic mechanism of this reaction.

Object race detection (2001)

We present an on-the-fly mechanism that detects access conflicts in executions of multi-threaded Java programs. Access conflicts are a conservative approximation of data races. The checker tracks access information at the level of objects (object races) rather than at the level of individual variables. This viewpoint allows the checker to exploit specific properties of object-oriented programs for optimization by restricting dynamic checks to those objects that are identified by escape analysis as potentially shared. The checker has been implemented in collaboration with an "ahead-of-time"Java compiler. The combination fo static program analysis (escape-analysis) and inline instrumentation during code generation allows us to reduce the runtime overhead of detecting access conflicts. This overhead amounts to about 16-129% in time and less than 25% in space for typical benchmark applications and compares favorably to previously published on-the-fly mechanism that incurred an overhead of about a factor of 2-80 in time and up to a factor of 2 in space.
Effect of cavity size on lasting characteristics of a distributed Bragg reflector-surface emitting laser with buried heterostructure (1992)

Transverse-mode characteristics of the distributed Bragg reflector-surface emitting laser diode with buried heterostructure were investigated as a function of the cavity size. Stable, fundamental transverse-mode operation was achieved for cavity openings of 4 μm in diameter and smaller. The effect of cavity size on threshold current and polarization characteristics is also discussed.
Canine risers: indications and techniques for their use. (2002)

Tooth wear leads to alterations in both static and functional occlusal contacts and may contribute to temporomandibular joint disorders and dysfunction. Treatment of tooth wear may be time consuming, expensive and destructive of remaining tooth tissues. Bruxism has been associated with the recording of abnormally high clenching forces. This paper describes a technique for the provision of the canine riser restoration, which deliberately alters the cuspal incline in canine teeth to provide a canine guided occlusion. These restorations may help to control excessive loading of teeth, limit further tooth wear and assist in the management of temporomandibular disorders and dysfunction.
Prostate specific antigen (PSA) may be a poor marker for progression of prostate cancer after treatment with a combination of chemo-hormonal therapies. (2008)

Prostate specific antigen (PSA) is typically the first indicator of relapse in patients treated for prostate cancer. Though radiographic progression with an undetectable PSA is clearly documented in the literature, this is an unusual event. We describe two cases of patients treated with a combination of androgen deprivation and chemotherapy for early stage but high risk prostate cancer who manifested clear evidence of radiographic relapse despite PSA values of <0.1 ng/mL. We hypothesize that patients with early stage prostate cancer treated with combinations of androgen deprivation and chemotherapy may be at high risk for this unusual pattern of relapse.
