BGP Prefix Independent Convergence (PIC) (2007)

With the explosive growth of the Internet and the growing deployment of layer 3 virtual private networks (L3VPN), the size of the Border Gateway Protocol (BGP) routing table has dramatically increased over the past years (in the 750K range in early 2007 counting Internet and L3VPN routes in a typical major Service Provider). Studies have shown that dynamics of BGP may cause several minutes of packet loss during network failures. This duration increases further as the routing table grows, as the traditional convergence oper- ation scales with the number of prefixes. In this paper, we present an alternate solution to provide BGP convergence and demonstrate that it is possible to limit the traffic loss period to sub-second for any failure occurring within the network of a service provider (SP) or on peering links with redundantly-connected peers. This covers the vast major- ity (if not all) of business models involving tight BGP con- vergence requirements. We term this alternate solution as BGP Prefix Independent Convergence (PIC) since it works by triggering an immediate and prefix-independent dataplane rerouting of the BGP destinations via the alternate path at In- terior Gateway Protocol (IGP) convergence time. We present experimental results of the convergence behavior based on a benchmark of a commercially available carrier router that supports the BGP PIC solution, and on BGP data provided by a Tier-1 ISP.
Cutting Force Analysis of Split Beam Connectors (1982)

The insertion process of a bare wire into a split beam is analyzed using the theories of metal cutting. The insertion and the wire entry force, which are two important design considerations for insulation displacement type connectors, are calculated theoretically and found to agree with the values obtained from the experiment.
Frequency‐independent blockade of cardiac Na+channels by riluzole: comparison with established anticonvulsants and class I anti‐arrhythmics (2000)

The Na+ channel blocking activity and the antiarrhythmic effects of riluzole, and established anticonvulsants (lamotrigine and lifarizine) and class I antiarrhythmics (lidocaine, flecainide and disopyramide) were studied under in vitro and in vivo conditions. Guinea-pig cardiac Purkinje fibres were superfused with Tyrode solution and electrically driven for recording action potentials with intracellular microelectrodes. In these preparations paced at 1 Hz, all compounds tested produced concentration-dependent (0.3-100 microM) reductions in the maximum rate of depolarization of the action potential (Vmax). For riluzole, phenytoin and carbamazepine this effect was frequency-independent (0.5-6 Hz) but for lamotrigine, lifarizine, lidocaine, flecainide and disopyramide it was frequency-dependent. In anaesthetized rats, riluzole, in contrast to flecainide, did not delay the appearance of aconitine-induced arrhythmias. Riluzole (0.3-3.9 mg/kg, i.v.) also lacked notable cardiac electrophysiological effects in anaesthetized dogs. At an i.v. dose of 3.0 mg/kg riluzole failed to restore a normal sinus rhythm in conscious dogs with polymorphic arrhythmias produced by ligation of the left anterior descending coronary artery 24 h earlier. These results indicate that riluzole, phenytoin and carbamazepine, unlike lamotrigine, lifarizine and flecainide, block cardiac Na+ channels in a frequency-independent manner. This property may account for the lack of antiarrhythmic activity of riluzole, phenytoin and carbamazepine in animal models of arrhythmias that respond to class I antiarrhythmic drugs. It may also account for the clinical observation that riluzole does not seem to cause the unfavourable electrocardiographic changes characteristic of drugs that block cardiac Na+ channels in a frequency-dependent manner.
Design and Analysis of a 3-Arm Spiral Antenna (2007)

A novel 3-arm spiral antenna structure is presented in this paper. This antenna similar to traditional two-arm or four-arm spiral antennas exhibits wideband radiation characteristic and circular polarization. Advantages offered by the new design are two fold. Unlike the traditional spiral antennas the three-arm spiral can be fed by an unbalanced transmission line, such as a coaxial line or coplanar waveguide, and therefore an external balun is not needed at the feed point. Also by proper choice of arms' dimensions the antenna can be directly matched to any practical transmission line characteristic impedance and therefore external matching networks are not required. This is accomplished by feeding the antenna at the outer radius by a coplanar waveguide (CPW) transmission line and tapering it towards the center. The antenna can also be fed from the center using a coaxial or CPW line perpendicular to the plane of the spiral antenna. A full-wave numerical simulation tool is used to optimize the geometry of the proposed 3-arm spiral to achieve a compact size, wide bandwidth operation, and low axial ratio. The antenna is also designed over a ground plane to achieve a unidirectional radiation and center loading is examined that improves the axial ratio. Simulated results like return loss, radiation pattern, gain, and axial ratio are compared with those obtained from measurements and good agreements are shown. Because of its unique feed structure and compact size, application of the proposed 3-arm spiral antenna for wideband array applications is demonstrated
Epidermal growth factor receptor-targeted therapy (2008)

High epidermal growth factor receptor (EGFR) expression is a feature of human tumours and is an adverse prognostic factor for radiotherapy outcome. High expression is associated with benefit from accelerated radiotherapy in patients with head and neck squamous cell carcinoma. Anti-EGFR strategies potentiate the effects of radiotherapy and the inhibition of deoxyribonucleic acid repair appears to be important amongst a wide range of mechanisms, which include effects on angiogenesis, differentiation and the immunological response. There is considerable interest in exploring combined modality therapies involving radiation and EGFR antagonists for the curative treatment of cancer patients. Important issues in designing new trials are to investigate optimal scheduling and to establish biobanks to develop biomarkers for future patient selection.
Influence of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) in polymer LEDs (2006)

We investigate the influence of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) on the optoelectronic properties of polymer light-emitting diodes containing poly(9,9-dioctylfluorene) (PFO). Electromodulation and $IV$ luminance measurements are reported for a series of devices with bare indium tin oxide (ITO) or PEDOT:PSS-coated ITO anodes and Ba or Al cathodes. The ITO/PFO/Al, ITO/PFO/Ba, and ITO/PEDOT:PSS/PFO/Al devices all exhibit conventional field-induced electromodulation behavior, in both forward and reverse bias, consistent with the Stark effect (SE). The ITO/PEDOT:PSS/PFO/Ba devices by contrast exhibit conventional behavior only for applied biases below the flat-band voltage; at higher biases, the field-induced SE features vanish and are replaced by anomalous charge-induced electromodulation features. This anomalous behavior is observed only when PEDOT:PSS is used in conjunction with a strongly electron-injecting cathode such as Ba, and is attributed to the presence of trapped electrons at the PEDOT:PSS-emitter interface, which screen the electric field from the bulk of the device. The enhanced field at the interface increases the rate of field-assisted hole injection into the highest occupied molecular orbital (HOMO) of the PFO, resulting in lower drive voltages and increased electroluminescence efficiencies.
Ab initio molecular simulations with numeric atom-centered orbitals (2009)

We describe a complete set of algorithms for ab initio molecular simulations based on numerically tabulated atom-centered orbitals (NAOs) to capture a wide range of molecular and materials properties from quantum-mechanical first principles. The full algorithmic framework described here is embodied in the Fritz Haber Institute “ab initio molecular simulations” (FHI-aims) computer program package. Its comprehensive description should be relevant to any other first-principles implementation based on NAOs. The focus here is on density-functional theory (DFT) in the local and semilocal (generalized gradient) approximations, but an extension to hybrid functionals, Hartree–Fock theory, and MP2/GW electron self-energies for total energies and excited states is possible within the same underlying algorithms. An all-electron/full-potential treatment that is both computationally efficient and accurate is achieved for periodic and cluster geometries on equal footing, including relaxation and ab initio molecular dynamics. We demonstrate the construction of transferable, hierarchical basis sets, allowing the calculation to range from qualitative tight-binding like accuracy to meV-level total energy convergence with the basis set. Since all basis functions are strictly localized, the otherwise computationally dominant grid-based operations scale as O(N) with system size N. Together with a scalar-relativistic treatment, the basis sets provide access to all elements from light to heavy. Both low-communication parallelization of all real-space grid based algorithms and a ScaLapack-based, customized handling of the linear algebra for all matrix operations are possible, guaranteeing efficient scaling (CPU time and memory) up to massively parallel computer systems with thousands of CPUs.
Simple nonlinear equalisers for binary baseband signals (1983)

Some very recent work on equalisers has led to a simple development of a conventional nonlinear (decision-feedback) equaliser, that involves only changes to the equalisation process itself and can, under certain conditions, give a useful improvement in tolerance to additive white Gaussian noise. The technique is particularly effective when binary data symbols are transmitted, at a high signal/noise ratio, and there is severe amplitude distortion in the received data signal. The paper is concerned with a further development of the technique, suitable for applications where a binary data signal is transmitted at a high rate over a linear baseband channel and where the channel introduces severe amplitude distortion. The channel may be either minimum phase or linear phase, or else it may approximate to some compromise between these two. It is shown that, under the given conditions, the linear feedforward transversal filter that forms the first part of a conventional nonlinear equaliser can often be replaced by a simple two-tap feedforward transversal filter, with either an improvement in performance or, at least, no serious degradation in performance. The paper describes both the new equaliser and a further development of this for the case where the received data signal is sampled at twice the data symbol rate. Finally, results of computer-simulation tests are presented, comparing the tolerances to additive white Gaussian noise of the two new equalisers with those of more conventional detectors, for models of various channels. Three quite different applications have been considered, one of which involves the transmission of digital data at 140 Mbit/s over a length of coaxial cable.
Role of left inferior prefrontal cortex in retrieval of semantic knowledge: A reevaluation (1997)

A number of neuroimaging findings have been interpreted as evidence that the left inferior frontal gyrus (IFG) subserves retrieval of semantic knowledge. We provide a fundamentally different interpretation, that it is not retrieval of semantic knowledge per se that is associated with left IFG activity but rather selection of information among competing alternatives from semantic memory. Selection demands were varied across three semantic tasks in a single group of subjects. Functional magnetic resonance imaging signal in overlapping regions of left IFG was dependent on selection demands in all three tasks. In addition, the degree of semantic processing was varied independently of selection demands in one of the tasks. The absence of left IFG activity for this comparison counters the argument that the effects of selection can be attributed solely to variations in degree of semantic retrieval. Our findings suggest that it is selection, not retrieval, of semantic knowledge that drives activity in the left IFG.
Disaggregating Hot Water Use and Predicting Hot Water Waste in Five Test Homes (2014)

While it is important to make the equipment (or "plant") in a residential hot water system more efficient, the hot water distribution system also affects overall system performance and energy use. Energy wasted in heating water that is not used is estimated to be on the order of 10%-30% of total domestic hot water (DHW) energy use. This field monitoring project installed temperature sensors on the distribution piping (on trunks and near fixtures) in five houses near Syracuse, NY, and programmed a data logger to collect data at 5 second intervals whenever there was a hot water draw. This data was used to assign hot water draws to specific end uses in the home as well as to determine the portion of each hot water that was deemed useful (i.e., above a temperature threshold at the fixture). Overall, the procedures to assign water draws to each end use were able to successfully assign about 50% of the water draws, but these assigned draws accounted for about 95% of the total hot water use in each home. The amount of hot water deemed as useful ranged from low of 75% at one house to a high of 91% in another. At three of the houses, new water heaters and distribution improvements were implemented during the monitoring period and the impact of these improvements on hot water use and delivery efficiency were evaluated.
Dynamic modeling and forecasting on enterprise revenue with derived granularities (2005)

Timely and accurate forecasts are crucial in decision-making processes and have significant impacts on many business aspects. We at HP Labs have developed a complete set of quantitative forecasting methods that can enable the establishment of a reliable predictive reporting system, so that executives can discern as early as possible where the company is heading financially. This paper reports some of our technical developments in building such a predictive reporting system.
The enlightened eye (1992)

This article reports on a qualitative study investigating Vietnamese EFL teachers' perceptions of sources of self-efficacy information. Findings suggested that four sources of efficacy information appeared to influence teachers' sense of self-efficacy. Contrary to widespread belief, mastery experiences were not the most influential source of efficacy information. Rather, social persuasion was. Study teachers reported various vicarious experiences and physiological/affective states as supplementary self-efficacy sources, including cognitive mastery experiences, which were deemed more powerful than enactive mastery experiences. The study highlights a range of Vietnamese cultural and contextual factors that influenced the way the teachers selected, weighed and interpreted efficacy information.
Using software component generators to construct a meta-weaver framework (2001)

Several new modularity technologies have been proposed that improve separation of concerns in programming languages. The initial efforts to demonstrate these technologies are usually focused on a single programming language. Since we live in a polyglot world, this proposal addresses the goal of being able to take these new powerful technologies to other languages. The approach uses software generators that create new weavers from meta-specifications of programming languages.

Billion-scale semi-supervised learning for image classification (2019)

This paper presents a study of semi-supervised learning with large convolutional networks. We propose a pipeline, based on a teacher/student paradigm, that leverages a large collection of unlabelled images (up to 1 billion). Our main goal is to improve the performance for a given target architecture, like ResNet-50 or ResNext. We provide an extensive analysis of the success factors of our approach, which leads us to formulate some recommendations to produce high-accuracy models for image classification with semi-supervised learning. As a result, our approach brings important gains to standard architectures for image, video and fine-grained classification. For instance, by leveraging one billion unlabelled images, our learned vanilla ResNet-50 achieves 81.2% top-1 accuracy on the ImageNet benchmark.
Multi-modal human robot interaction for map generation (2002)

Describes an interface for multi modal human robot interaction, which enables people to introduce a newcomer robot to different attributes of objects and places in the room through speech commands and hand gestures. The robot makes an environment map of the room based on knowledge learned through communication with human and uses this map for navigation. The developed system consists of several sections including: natural language processing, posture recognition, object localization and map generation. This system uses a combination of multiple sources of information and model matching to detect and track a human hand so that the user can point toward an object of interest and guide the robot to go near to it or locate that object's position in the room. The position of objects in the room is located by a monocular camera vision and depth from focus method.

An improved system for estradiol-dependent regulation of gene expression in yeast (2007)

The feedback regulatory loop that we have engineered allows a 250-fold induction of the regulated gene, without increasing the basal activity of the target promoter, and achieving a 12-fold higher regulation efficiency than the previous configuration.
Large-scale Knowledge Base Completion (2015)

Constructing large-scale knowledge bases has attracted much attention in recent years, for which Knowledge Base Completion (KBC) is a key technique. In general, inferring new facts in a large-scale knowledge base is not a trivial task. The large number of inferred candidate facts has resulted in the failure of the majority of previous approaches. Inference approaches can achieve high precision for formulas that are accurate, but they are required to infer candidate instances one by one, and extremely large candidate sets bog them down in expensive calculations. In contrast, the existing embedding-based methods can easily calculate similarity-based scores for each candidate instance as opposed to using inference, so they can handle large-scale data. However, this type of method does not consider explicit logical semantics and usually has unsatisfactory precision. To resolve the limitations of the above two types of methods, we propose an approach through Inferring via Grounding Network Sampling over Selected Instances. We first employ an embedding-based model to make the instance selection and generate much smaller candidate sets for subsequent fact inference, which not only narrows the candidate sets but also filters out part of the noise instances. Then, we only make inferences within these candidate sets by running a data-driven inference algorithm on the Markov Logic Network (MLN), which is called Inferring via Grounding Network Sampling (INS). In this process, we especially incorporate the similarity priori generated by embedding-based models into INS to promote the inference precision. The experimental results show that our approach improved [email protected] from 32.911% to 71.692% on the FB15K dataset and achieved much better [email protected] evaluations than state-of-the-art methods.
Measurements of Cavity Ringdown Spectroscopy of Acetone in the Ultraviolet and Near-Infrared Spectral Regions: Potential for Development of a Breath Analyzer (2004)

We report a study on the cavity ringdown spectroscopy of acetone in both the ultraviolet (UV) and the near-infrared (NIR) spectral regions to explore the potential for development of a breath analyzer for disease diagnostics. The ringdown spectrum of acetone in the UV (282.4-285.0 nm) region is recorded and the spectrum is in good agreement with those obtained by other spectral techniques reported in the literature. The absorption cross-section of the C-H stretching overtone of acetone in the NIR (1632.7-1672.2 nm) is reported for the first time and the maximum absorption cross-section located at 1666.7 nm is 1.2 x 10(-21) cm(2). A novel, compact, atmospheric cavity with a cavity length of 10 cm has been constructed and implemented to investigate the technical feasibility of the potential instrument size, optical configuration, and detection sensitivity. The detection limit of such a mini cavity employing ringdown mirrors of reflectivity of 99.85% at 266 nm, where acetone has the strongest absorption, is approximately 1.5 ppmv based on the standard 3 criteria. No real breath gas samples are used in the present study. Discussions on the detection sensitivity and background spectral interferences for the instrument development are presented. This study demonstrates the potential of developing a portable, sensitive breath analyzer for medical applications using the cavity ringdown spectral technique.
