Interaction of Daylength and Applied Gibberellins on Stem Growth and Leaf Production in Three Varieties of Celery (1987)

Pressman, E. and Negbi, M. 1987. Interaction of daylength and applied gibberellins on stem growth and leaf production in three varieties of celery.—J. exp. Bot. 38: 968–971. Exogenous application of gibberellins (GAs) stimulated stem length. The extent of this stimulation was less in long photoperiods, as long days (LD) or as long nights interrupted by night breaks (NB), than it was in short days (SD). Long photoperiods increased the length and erectness of leaves and reduced leaf number. Similar morphological changes were stimulated by applied GAs, which were more effective on plants grown in SD than on those in LD. It is suggested that long photoperiods cause these morphological changes via the production or metabolism of endogenous GAs, but it is not clear how endogenous GAs interact with the applied ones.
Spatiotemporal variance-guided filtering (2017)

We introduce a reconstruction algorithm that generates a temporally stable sequence of images from one path-per-pixel global illumination. To handle such noisy input, we use temporal accumulation to increase the effective sample count and spatiotemporal luminance variance estimates to drive a hierarchical, image-space wavelet filter [Dammertz et al. 2010]. This hierarchy allows us to distinguish between noise and detail at multiple scales using local luminance variance.
Immune regulation of metastasis: mechanistic insights and therapeutic opportunities (2018)

Metastatic disease is the leading cause of death in cancer patients. Metastasis formation involves a cascade of events for which the underlying mechanisms are still poorly understood. During the metastatic cascade, cancer cells tightly interact with the immune system and they influence each other, both in the tumor microenvironment and systemically. The crosstalk between cancer and immune cells adds another layer of complexity to our understanding of metastasis formation, but at the same time opens new therapeutic opportunities for cancer patients. The intensifying development of immunotherapeutic strategies calls for a better understanding of immune regulation of metastasis in order to maximize the therapeutic benefit for patients with metastatic disease. In this Review and accompanying poster, we describe the main mechanisms of immune regulation of metastasis that have been reported to date, and present promising immunotherapeutic options that are currently available, or may become so in the near future, to tackle metastasis.
Digital Photoplethysmography for Assessment of Arterial Stiffness: Repeatability and Comparison with Applanation Tonometry (2015)

For estimation of the LV function, ETc, EEI and b/a are suitable, for large artery stiffness EEI, and for small arteries DI and DDI. The only global parameter, AI, showed a high repeatability and the overall best correlations with AIX and PWV.
Innate Stat3-mediated induction of the antimicrobial protein Reg3γ is required for host defense against MRSA pneumonia (2013)

Pulmonary Staphylococcus aureus (SA) infections are a public health concern and a major complication of hyper-IgE syndrome, caused by mutations in STAT3. In contrast to previous findings of skin infection, we observed that clearance of SA from the lung did not require T, B, or NK cells but did require Stat3 activation. Immunohistochemistry showed robust Stat3 phosphorylation in the lung epithelium. We identified that a critical Stat3 target gene in lung epithelium is Reg3g (regenerating islet-derived 3 γ), a gene which is highly expressed in gastrointestinal epithelium but whose role in pulmonary host defense is uncharacterized. Stat3 regulated Reg3g transcription through direct binding at the Reg3g promoter region. Recombinant Reg3γ bound to SA and had both bacteriostatic and bactericidal activity in a dose-dependent fashion. Stat3 inhibition in vivo reduced Reg3g transcripts in the lung, and more importantly, recombinant Reg3γ rescued mice from defective SA clearance. These findings reveal an antibacterial function for lung epithelium through Stat3-mediated induction of Reg3γ.
A framework for adaptive voice communication over wireless channels (2003)

Time-varying channel error conditions of a wireless link do not allow for providing a steady service quality. Adaptability is one way to go around this problem since the quality of service (QoS) requirements can be changed as the channel status changes. In this paper, we propose a framework for adaptive voice over one-hop wireless communication between a source and a destination. Adaptability is achieved at two levels: (1) changing the voice-encoding rate, and (2) changing the signal modulation scheme. In addition to reacting to the channel conditions and hence achieving better quality, adaptation, will allow for the support of more of the offered load (i.e., higher multiplexing gain). This will introduce some issues and problems; the goal was to reach to a near-optimal operating point, where quality is not traded for bandwidth efficiency. We simulated a special case of the framework. Results show that the adaptive approach has a much less degradation in voice quality (DVQ) and allows for more voice communications to be supported.

Boosting the Accuracy of Differentially-Private Queries Through Consistency (2009)

Recent differentially private query mechanisms offer strong privacy guarantees by adding noise to the query answer. For a single counting query, the technique is simple, accurate, and provides optimal utility. However, analysts typically wish to ask multiple queries. In this case, the optimal strategy is not apparent, and alternative query strategies can involve difficult trade-offs in accuracy, and may produce inconsistent answers. In this work we show that it is possible to significantly improve accuracy for a general class of histogram queries. Our approach carefully chooses a set of queries to evaluate, and then exploits consistency constraints that should hold over the noisy output. In a post-processing phase, we compute the consistent input most likely to have produced the noisy output. The final output is both private and consistent, but in addition, it is often much more accurate. We apply our techniques to real datasets and show they can be used for estimating the degree sequence of a graph with extreme precision, and for computing a histogram that can support arbitrary range queries accurately.

Cognitive Radio Trial Environment: First Live Authorized Shared Access-Based Spectrum-Sharing Demonstration (2013)

Cognitive radio system (CRS) technology can help respond to the growing mobile traffic demand by improving network resource usage and gaining access to new shared spectrum bands. This article presents a cognitive radio trial environment (CORE) consisting of cognitive engines (CEs) to control different radio systems [e.g., long-term evolution (LTE) and wireless open-access research platform (WARP)-based networks]. Load balancing and authorized shared access (ASA) are demonstrated using the trial environment with promising results. The ASA-based spectrum sharing trial is presented for the first time with a real-life mobile network accessing a shared spectrum band under a licensed shared access (LSA) regime. Cognitive decision making brings intelligence to the usage of the radio and network resources and, at best, increases considerably end users? quality of service (QoS) compared to the standard systems, as shown for QoS-based offloading.

The Application of Nanomaterials for the Electrochemical Detection of Antibiotics: A Review (2021)

Antibiotics can accumulate through food metabolism in the human body which may have a significant effect on human safety and health. It is therefore highly beneficial to establish easy and sensitive approaches for rapid assessment of antibiotic amounts. In the development of next-generation biosensors, nanomaterials (NMs) with outstanding thermal, mechanical, optical, and electrical properties have been identified as one of the most hopeful materials for opening new gates. This study discusses the latest developments in the identification of antibiotics by nanomaterial-constructed biosensors. The construction of biosensors for electrochemical signal-transducing mechanisms has been utilized in various types of nanomaterials, including quantum dots (QDs), metal-organic frameworks (MOFs), magnetic nanoparticles (NPs), metal nanomaterials, and carbon nanomaterials. To provide an outline for future study directions, the existing problems and future opportunities in this area are also included. The current review, therefore, summarizes an in-depth assessment of the nanostructured electrochemical sensing method for residues of antibiotics in different systems.
The effects of heart rate on the action potential of guinea‐pig and human ventricular muscle. (1981)

1. On increasing the stimulation frequency of isolated pieces of guinea-pig ventricular muscle, the resting potential depolarizes, and the action potential duration and amplitude are reduced. On termination of the high frequency train of action potentials, these changes are reversed. 2. The resting potential changes are roughly exponential, with a time constant of the order of 10 sec, and are attributable to K+ accumulation in the extracellular space. They are not explicable in terms of known gating variables. 3. The action potential duration and amplitude recover much more slowly than the resting potential, after a high frequency train (half-time approximately 5 min). The time course of these recoveries is not exponential, and is slower after trains which produce more shortening of the action potential. The slow time course suggests that K+ accumulation is not the main cause of the changes in action potential shape. Furthermore, when a certain depolarization of the resting potential is produced by a high frequency train, there is a greater reduction of the action potential duration than that which occurs when the bathing [K+] is raised to produce the same depolarization (Reiter & Stickel, 1968). This is so even when a gradient of extracellular [K+] is induced in the preparation, to mimic non-uniform K+ accumulation. 4. Similarly, the shortening of the action potential produced by toxic doses or cardiotonic steroids is probably not the result of K+ accumulation. 5. The slow changes of the action potential shape produced by a high frequency train are not attributable to the effects of gating variables, nor (solely) to a rise in the intracellular Na concentration stimulating the electrogenic Na/K pump. The dye 3,3'-diethylthiadicarbocyanine, which blocks the Ca2+-activated K conductance in the erythrocyte, has no significant effect on the shape changes. 6. After a sudden change in heart rate, the QT interval of the human electrocardiogram (e.c.g.) changes slowly to a new equilibrium value. The time course of this change is similar to that of the action potential duration in guinea-pig ventricle following a change in stimulation frequency. These changes of the e.c.g. are probably not due to slow alterations of neural or hormonal factors extrinsic to the heart. In the whole heart, the effects on the ventricular action potential duration of changes in sympathetic or vagal tone, or of circulating catecholamines, can be largely accounted for by the changes of atrial driving frequency they produce.
Noninvasive identification of fluids by swept-frequency acoustic interferometry (2023)

A method for rapid, noninvasive identification and monitoring of chemicals in sealed containers or containers where direct access to the chemical is not possible is described. Multiple ultrasonic acoustic properties (up to four) of a fluid are simultaneously determined. The present invention can be used for chemical identification and for determining changes in known chemicals from a variety of sources. It is not possible to identify all known chemicals based on the measured parameters, but known classes of chemicals in suspected containers, such as in chemical munitions, can be characterized. In addition, a large number of industrial chemicals can be identified.
Real-time visual recognition of facial gestures for human-computer interaction (2002)

People naturally express themselves through facial gestures and expressions. Our goal is to build a facial gesture human-computer interface for use in robot applications. We have implemented an interface that tracks a person's facial features in real time (30 Hz). Our system does not require special illumination nor facial makeup. By using multiple Kalman filters we accurately predict and robustly track facial features. This is despite disturbances and rapid movements of the head (including both translational and rotational motion). Since we reliably track the face in real-time we are also able to recognise motion gestures of the face. Our system can recognise a large set of gestures (13) ranging from "yes", "no" and "may be" to detecting winks, blinks and sleeping.
Localizing Failure Root Causes in a Microservice through Causality Inference (2020)

An increasing number of Internet applications are applying microservice architecture due to its flexibility and clear logic. The stability of microservice is thus vitally important for these applications' quality of service. Accurate failure root cause localization can help operators quickly recover microservice failures and mitigate loss. Although cross-microservice failure root cause localization has been well studied, how to localize failure root causes in a microservice so as to quickly mitigate this microservice has not yet been studied. In this work, we propose a framework, MicroCause, to accurately localize the root cause monitoring indicators in a microservice. MicroCause combines a simple yet effective path condition time series (PCTS) algorithm which accurately captures the sequential relationship of time series data, and a novel temporal cause oriented random walk (TCORW) method integrating the causal relationship, temporal order, and priority information of monitoring data. We evaluate MicroCause based on 86 real-world failure tickets collected from a top tier global online shopping service. Our experiments show that the top 5 accuracy (AC@5) of MicroCause for intra-microservice failure root cause localization is 98.7%, which is greatly higher (by 33.4 %) than the best baseline method.
Ultra-High Data-Rate 60 GHz Radio-Over-Fiber Systems Employing Optical Frequency Multiplication and OFDM Formats (2010)

The increasing demand for wireless video-based interactive and multimedia data services explains why 60-GHz millimeter-wave wireless system is a promising candidate to provide multi-gigabit-per-second wireless services. While attempting to generate and transmit 60 GHz signals in a wireless system cost effectively and increase the spectral efficiency to facilitate multi-gigabit-per-second services, this work reviews three radio-over-fiber (RoF) systems based on optical frequency multiplication (up to 6 times) to reduce the bandwidth requirement of optical transmitters. Additionally, orthogonal frequency division multiplexing (OFDM) signals with multi-level modulation formats (16 QAM) are utilized to achieve an ultrahigh data rate of 28 Gbps within the 7-GHz license-free band and compensate for an uneven frequency response of 60-GHz RoF systems. Negligible power penalty following 25-km standard single mode fiber (SSMF) transmission is observed, capable of significantly extending the service range to various applications within a building or campus.

Biocompatibility of Electrochemical Glucose Sensors Implanted in the Subcutis of Pigs (2006)

The reported in vivo bioinstability of sensors is likely to be caused by protein and cellular biofouling on the sensor membrane. Furthermore, the consistent finding of fibrinogen and fibrinogen fragments D and E at the sensor-tissue interface seems to play an important role in the pathogenesis as it possibly maintains the inflammation by promoting the recruitment of inflammatory cells to the implantation site.
Applications of Lentiviral Vectors for Biology and Gene Therapy of Neurological Disorders (2008)

Recombinant lentiviral vectors (rLV) are powerful tools for gene transfer to the central nervous system (CNS) and hold great potential as a therapeutic gene therapy strategy for neurological disorders. Recent data indicate that rLVs are suitable for functional studies in the CNS by over expression or knock down of specific proteins. Based on a variety of lentiviruses species, different vector systems have been developed. However, the most commonly used rLV vector is based on the human immunodeficiency virus 1 (HIV-1). Here we describe the use of such vectors to achieve cell-specific transgene expression in the brain. In this setting, rLVs are versatile tools both due to their relatively large cloning capacity and their ability to transduce non-dividing cells. Furthermore, we discuss the preclinical development of gene therapy based on enzyme replacement and/or delivery of neurotrophic factors for neurodegenerative diseases and CNS manifestations of lysosomal storage diseases. Neuroprotective strategies that aim to deliver glial cell line-derived neurotrophic factor and ciliary neurotrophic factor for Parkinson's and Huntington's diseases in particular have been documented with success in appropriate animal models. More recently, rLVs were shown to be suitable to express small interfering RNA for treatment in models of Alzheimer's disease and amyotrophic lateral sclerosis. Finally, we present a review of the use of rLVs to model neurodegenerative diseases. rLVs have proven to be a very versatile tool to create genetic models of both Parkinson's and Huntington's diseases and thus provide possibilities to study complex genetic interactions in otherwise wild-type animals evading the necessity to create transgenic mice. Moreover, the potential of these vectors in the development of gene therapy to treat neurological disorders is considerable, which is supported by the fact that clinical trials using rLVs are underway.
Interactions of xenobiotics with the steroid hormone biosynthesis pathway (2003)

Environmental contaminants can potentially disrupt endocrine processes by interfering with the function of enzymes involved in steroid synthesis and metabolism. Such interferences may result in reproductive problems, cancers, and toxicities related to (sexual) differentiation, growth, and development. Various known or suspected endocrine disrupters interfere with steroidogenic enzymes. Particular attention has been given to aromatase, the enzyme responsible for the conversion of androgens to estrogens. Studies of the potential for xenobiotics to interfere with steroidogenic enzymes have often involved microsomal fractions of steroidogenic tissues from animals exposed in vivo, or in vitro exposures of steroidogenic cells in primary culture. Increasingly, immortalized cell lines, such as the H295R human adrenocortical carcinoma cell line are used in the screening of effects of chemicals on steroid synthesis and metabolism. Such bioassay systems are expected to play an increasingly important role in the screening of complex environmental mixtures and individual contaminants for potential interference with steroidogenic enzymes. However, given the complexities in the steroid synthesis pathways and the biological activities of the hormones, together with the unknown biokinetic properties of these complex mixtures, extrapolation of in vitro effects to in vivo toxicities will not be straightforward and will require further, often in vivo, investigations.
AlGaN/GaN metal-insulator-semiconductor heterostructure field-effect transistor with an <i>in-situ</i> AlN cap layer (2011)

In this study, we investigate AlGaN/GaN metal-insulator-semiconductor heterostructure field-effect transistor with an in-situ AlN cap layer with regards to DC-, RF-, and power-performance. This “earlier” passivation by in-situ AlN cap layer protects the surface during processing and neutralizes the charges at the top of AlGaN interface, which leads to a higher electron density of channel and superior device characteristics.
E-commerce and web 3D for involving the customer in the design process (2012)

This paper aims to show to what extent the Web3D is an advantage for Living Lab paradigm. A state-of-the-art of Web3D solutions for e-commerce enabled us to select the most suitable functionalities and properties for designing a gates 3D configurator for person from the general public. This project was done in the context of an Action-Research. Twenty seven participants evaluated this tool. Results show that an interactive 3-dimensional visualization of the object is an advantage for the sale, because a single image does not usually allow user to imagine the product in its future environment. The use of Web3D for e-commerce gives the customer the ability to get involved in the design process. This point is a first answer to a research question on the role and definition of Living Labs.
