Distributed clocks in slotted networks (2003)

A simple technique is described for operating slotted loop or mesh networks with independent, and slightly different clocks at every node. The technique eliminates the need to designate one node as the master clock in these networks. The technique can also be used to transfer synchronous samples from a voice source. If the slots correspond to time-division multiplexed (TDM) frames of voice samples, the TDM frames from all of the input lines arrive at a switching point in the node simultaneously, and the samples can be interchanged by standard telephone switching techniques.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
InGaAs/In(AlGa)As RHET's with InAs pseudomorphic base (1992)

An InGaAs/In(AlGa)As resonant-tunneling hot-electron transistor (RHET) with an INAs pseudomorphic base to increase current gain and to reduce base resistance was designed and fabricated. The conduction band discontinuity between the InAs base and the In(AlGa)As collector barrier was estimated from the thermionic current. The band discontinuity was about 0.38 eV, which agrees well with the calculated band discontinuity taking into consideration the effect of strain. The common-emitter current gain doubled and the base resistance decreased 20% compared to InGaAs-base RHETs with the same doping concentration. A current gain cutoff frequency of 65 GHz and a maximum oscillation frequency of 50 GHz at 77 K were measured.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

XS, S, M, L: Creative Text Generators of Different Scales (2013)

Creative text generation projects of different sizes (in terms of lines of code and length of development time) are described. “Extra-small, ” “small, ” “medium, ” and “large” projects are discussed as participating in the practice of creative computing differently. Different ways in which these projects have circulated and are being used in the community of practice are identified. While large-scale projects have clearly been important in advancing creative text generation, the argument presented here is that the other types of projects are also valuable and that they are undervalued (particularly in computer science and strongly related fields) by current structures of higher education and academic communication – structures which could be changed.
EnaCloud: An Energy-Saving Application Live Placement Approach for Cloud Computing Environments (2009)

With the increasing prevalence of large scale cloud computing environments, how to place requested applications into available computing servers regarding to energy consumption has become an essential research problem, but existing application placement approaches are still not effective for live applications with dynamic characters. In this paper, we proposed a novel approach named EnaCloud, which enables application live placement dynamically with consideration of energy efficiency in a cloud platform. In EnaCloud, we use a Virtual Machine to encapsulate the application, which supports applications scheduling and live migration to minimize the number of running machines, so as to save energy. Specially, the application placement is abstracted as a bin packing problem, and an energy-aware heuristic algorithm is proposed to get an appropriate solution. In addition, an over-provision approach is presented to deal with the varying resource demands of applications. Our approach has been successfully implemented as useful components and fundamental services in the iVIC platform. Finally, we evaluate our approach by comprehensive experiments based on virtual machine monitor Xen and the results show that it is feasible.
Selective ion-sensing with membrane-functionalized electrolyte-gated carbon nanotube field-effect transistors (2014)

In this work the ion-selective response of an electrolyte-gated carbon-nanotube field-effect transistor (CNT-FET) towards K(+), Ca(2+) and Cl(-) in the biologically relevant concentration range from 10(-1) M to 10(-6) M is demonstrated. The ion-selective response is achieved by modifying the gate-electrode of an electrolyte-gated CNT-FET with ion-selective membranes, which are selective towards the respective target analyte ions. The selectivity, assured by the ion-selective poly(vinyl chloride) based membrane, allows the successful application of the herein proposed K(+)-selective CNT-FET to detect changes in the K(+) activity in the μM range even in solutions containing different ionic backgrounds. The sensing mechanism relies on a superposition of both an ion-sensitive response of the CNT-network as well as a change of the effective gate potential present at the semiconducting channel due to a selective and ion activity-dependent response of the membrane towards different types of ions. Moreover, the combination of a CNT-FET as a transducing element gated with an ion-selective coated-wire electrode offers the possibility to miniaturize the already well-established conventional ion-selective electrode setup. This approach represents a valuable strategy for the realization of portable, multi-purpose and low-cost biosensing devices.
Integrating complement into the molecular pathogenesis of Hidradenitis Suppurativa (2019)

Complement inhibition has been identified as a potential therapeutic target for multiple inflammatory disorders including Hidradenitis Suppurativa (HS). It is currently unclear how complement integrates into our current model of molecular pathogenesis in HS and whether it represents a central component of pathogenesis, or a neutrophil-associated bystander. Levels of C5a in serum and tissue correlate with disease activity and degree of neutrophilic infiltrates in HS. C5a has been associated with Th17 immune axis activation in psoriasis, rheumatoid arthritis and Crohn's disease with strong similarities to TH17 activation in HS. Porphyromonas species (which are identified in the HS microbiome) are able to cleave inactive C5 into C5a implicating the cutaneous microbiome as an activator of complement. C3a and C5a are associated with activation of the NLRP3 inflammasome, implicated in the inflammatory drive in HS. Complement receptors are present upon dendritic cells, monocytes, fibroblasts and adipocytes, which may broaden the potential contribution of complement to multiple aspects of HS pathogenesis. Dysregulation of complement receptor pathways has been documented in obesity, insulin resistance and polycystic ovarian syndrome leading to the possibility that complement may explain the epidemiological associations between these conditions and HS. The therapeutic potential of complement inhibitors in HS may be related to the therapeutic target (complement receptor or complement subunit) and the presence of alternate receptors (such as C5aR2) or ligands (including C3a, PAMPs and DAMPs). Integrating complement into the known pathogenesis of HS may aid in explaining the contradictory results between Phase 2 studies of C5a antagonists. It also allows for the identification of existing knowledge gaps to target further clinical investigation and research.
Modeling and characterization of a merged PiN Schottky diodes with semi-super junction structure (2006)

In this paper a novel merged PiN Schottky rectifier structure based on semi-super junction technique, which is the combination of super junction (SJ) structure and n-bottom assisted layer (BAL), is proposed and demonstrated for a power-switching device. Optimal diode design is obtained exploiting a two dimension analytical model. Devices such as the blocking characteristic, the forward voltage-drop and the reverse recovery are analyzed with two-dimensional numerical simulations and compared with conventional SJ MPS and PiN diodes. The proposed structure without increasing the process difficulty and the cost is very attractive for high voltage and freewheeling rectifiers due to the low forward voltage drop and the soft recovery
Recent Advances in Electrolytes for Lithium–Sulfur Batteries (2015)

The rapidly increasing demand for electrical and hybrid vehicles and stationary energy storage requires the development of “beyond Li‐ion batteries” with high energy densities that exceed those of state‐of‐the‐art Li‐ion batteries. Li–S batteries, which have very high theoretical capacities and energy densities, are believed to be one of the most promising candidates. The sulfur‐based electrochemical reaction requires novel electrolytes to replace the classical carbonate‐based electrolyte systems inherited from Li‐ion batteries because carbonates are incompatible with the intermediate polysulfides in Li–S batteries. In addition, the theoretical specific capacities and projected energy densities of Li–S batteries are difficult to achieve experimentally, mainly because of the electronically insulating nature of sulfur and lithium sulfide cathodes, and the shuttle effect; this is a serious issue associated with the dissolution and diffusion of soluble polysulfides in most potential electrolytes and causes rapid capacity fading. It is therefore highly desirable to explore, modify, and/or optimize electrolytes for Li–S batteries to address these issues and improve their capacities, cycling stabilities, rate performances, and energy densities. An overview of recent developments in electrolytes for Li–S batteries is provided with a focus on the chemistry of polysulfides in different electrolyte media, including polysulfide solubility and its relevance to battery performance.
Abstract 1036: Cbl-independent degradation of Met: Ways to avoid agonism of bivalent Met targeting antibody. (2013)

Abstract The Met receptor tyrosine kinase, found to be constitutively activated in many tumors, has become a leading target for cancer therapy. Disruptions in Met down-regulation have been associated with aggressive tumor progression with several therapeutic strategies addressing this aspect of Met biology. Cbl E3 ligase-mediated degradation, which attenuates Met signaling via ligand-dependent Met internalization, is a major negative regulator of Met expression. It is believed that one of the mechanisms by which the therapeutic anti-Met antibodies induce cancer cell death in Met over-expressing tumors is via internalization and subsequent degradation of Met from the cell surface. However, a previously reported Met targeting antibody demonstrated intrinsic agonistic activity while capable of inducing Cbl-mediated degradation of Met, suggesting that Cbl-mediated degradation requires receptor activation and impedes therapeutic application. We have developed a potent and selective bivalent Met targeting antibody (SAIT301) that invokes Met degradation using an alternative regulator LRIG1. In this report, we demonstrate that LRIG1 mediates degradation of Met by SAIT301 and this degradation does not require Met activation. Furthermore, SAIT301 was able to down-regulate Met and dramatically inhibit growth of tumors with low or no Cbl expression, as well as tumors with Met exon 14 deletion that prevents Met binding to Cbl. In summary, we demonstrate the enhanced therapeutic potential of a novel tumor-inhibiting anti-Met antibody, SAIT301, which utilizes a Cbl-independent, LRIG1-mediated Met degradation pathway and thereby avoids the agonism that limits the effectiveness of previously reported anti-Met antibodies.

Duplication of 17q11.2 and Features of Albright Hereditary Osteodystrophy Secondary to Methylation Defects within the GNAS Cluster: Coincidence or Causal? (2013)

We report a case of Albright hereditary osteodystrophy (AHO) in a three-year-old girl with a microduplication at 17q11.2. The child developed obesity within the first 6 months of life. A diagnosis of Albright was made at age 2 years when biochemical evidence of parathyroid resistance was found. No mutations were identified in guanine nucleotide-binding protein G (s) subunit alpha (GNAS1). Subsequent investigations revealed methylation disturbance at GNAS1A, neuroendocrine secretory protein antisense (NESPAS) and neuroendocrine secretory protein 55 (NESP55) confirming a diagnosis of pseudohypothyroidism type 1B. A deletion of NESP55 and uniparental disomy chromosome 20 were excluded which suggested that the features of AHO arose through a purely epigenetic mechanism. Further investigation revealed a de novo microduplication at 17q11.2 encompassing the neurofibromatosis type 1 (NF1) gene. The combination of two rare de novo events in the same child raises the possibility that duplication of a gene within the 17q11.2 region may have triggered abnormal methylation in the GNAS cluster region on chromosome 20.

Branch and Bound for Piecewise Linear Neural Network Verification (2019)

The success of Deep Learning and its potential use in many safety-critical applications has motivated research on formal verification of Neural Network (NN) models. In this context, verification involves proving or disproving that an NN model satisfies certain input-output properties. Despite the reputation of learned NN models as black boxes, and the theoretical hardness of proving useful properties about them, researchers have been successful in verifying some classes of models by exploiting their piecewise linear structure and taking insights from formal methods such as Satisifiability Modulo Theory. However, these methods are still far from scaling to realistic neural networks. To facilitate progress on this crucial area, we exploit the Mixed Integer Linear Programming (MIP) formulation of verification to propose a family of algorithms based on Branch-and-Bound (BaB). We show that our family contains previous verification methods as special cases. With the help of the BaB framework, we make three key contributions. Firstly, we identify new methods that combine the strengths of multiple existing approaches, accomplishing significant performance improvements over previous state of the art. Secondly, we introduce an effective branching strategy on ReLU non-linearities. This branching strategy allows us to efficiently and successfully deal with high input dimensional problems with convolutional network architecture, on which previous methods fail frequently. Finally, we propose comprehensive test data sets and benchmarks which includes a collection of previously released testcases. We use the data sets to conduct a thorough experimental comparison of existing and new algorithms and to provide an inclusive analysis of the factors impacting the hardness of verification problems.
The development of breast carcinoma in women with thyroid carcinoma (2001)

Women with a history of thyroid carcinoma have a greater than expected risk of developing breast carcinoma. This risk is most pronounced in premenopausal white women. The implications of this observation with respect to breast carcinoma screening guidelines and thyroid carcinoma treatment guidelines deserve further investigation.
Synthesis of oxindole derivatives from <i>N</i>‐alkenyl‐<i>o</i>‐chloroanilides with zero‐valent nickel complex (1985)

Abstract Oxindole derivatives have been obtained from N ‐alkenyl‐ o ‐chloroanilides by reaction with tetrakis(triphenylphosphine)nickel(0) in toluene as solvent in good yields. A detailed analysis of all the products of the reaction allows to confirm the postulated mechanism of the cyclization reaction. The o ‐chloroanilides of the 3‐cyclohexenylacetic acid fails in the cyclization reaction, since the torsional hindrance seems to avoid that the endocyclic double bond may be orthogonally to the ortho ‐σ‐nickel complex intermediate on the aromatic ring.

The Phrenic Nerve And Atrial Fibrillation Ablation Procedures. (2009)

Radiofrequency ablation is increasingly used as an option to optimally manage patients with symptomatic atrial fibrillation. Presently, ablationists strive to improve success rates, particularly with persistent atrial fibrillation, while simultaneously attempting to reduce complications. A well-recognized complication with atrial fibrillation ablation is injury to the phrenic nerve giving rise to diaphragmatic paresis and patient discomfort.Phrenic nerve damage may occur when performing common components of atrial fibrillation ablation including pulmonary and superior vena caval isolation. The challenge for ablationists is to successfully target the arrhythmogenic substrate while avoiding this complication. In order to do this, a thorough knowledge of phrenic nerve anatomy, points in the ablation procedure where nerve damage is more likely, and an understanding of the presently utilized techniques to avoid this complication is required. In addition, when this complication does arise, prompt recognition of its occurrence, knowledge of the natural history, and available methods for management are needed.In this review, we discuss the underlying anatomic principles, techniques of avoiding phrenic nerve damage, and presently available methods of diagnosing and managing this complication.
Single-cell concepts for obtaining photovoltaic conversion efficiency over 30 percent (1985)

Although solar photovoltaic conversion efficiencies over 30 percent (one sun, AM1) can be expected for multiple-cell configurations using spectral splitting techniques, the highest practical single-cell conversion efficiency that can be attained using present concepts is estimated to be about 27-28 percent. To achieve conversion efficiencies above 30 percent using single-cell configurations it will be necessary to employ different concepts, such as spectral compression and broad-band detection. The implementation of these concepts would require major breakthroughs that are not anticipated in the near future.
Cultural Heritage Layers: Integrating Historic Media in Augmented Reality (2009)

In this paper we are presenting Cultural Heritage Layers, an approach that enables the visualization of historic media like drawings, paintings and photographs of buildings and historic scenes seamlessly superimposed on reality via video see through using X3D. This enables simple, inexpensive and sustainable Augmented Reality applications in the cultural heritage and architectural area based on industry standards. The main idea is to use existing historic media from archives and superimpose them seamlessly on reality at the right spot. These locative layers are context sensitively telling the location's history and create the impression of a virtual time journey. The registration of the virtual objects in the video images is provided by a robust 6DOF tracking framework based on two technologies that work in tandem: an initialization step based on Randomized Trees and a frame-to-frame tracking phase based on KLT. The entire application runs in real time on current Ultra Mobile PCs and MIDs.
An analysis of volatiles in the headspace of the faeces of neonates (2008)

A gas chromatography/mass spectrometry (GCMS) analysis of the headspace from the faeces of neonates was undertaken to record the volatiles associated with preterm babies on a neonatal unit. The compounds ethanol, acetone, 2-ethyl-1-hexanol, 3-methylbutanal, hexanal and 2,3-butanedione occurred with the highest frequency. The volatiles analysed were then compared to a previously published study of the volatiles from asymptomatic adult faeces. Fewer compounds were found in the neonatal faeces and virtually no sulfides were detected, in contrast to the adult samples where carbon disulfide, dimethyl disulfide and dimethyl sulfide were ubiquitous. In addition, 7 of the most abundant 15 volatile compounds were found to be aldehydes, while in contrast only 2, acetaldehyde and benzaldehyde, were present in the most abundant 15 compounds found in the headspace of adult faeces. 2-Ethyl-1-hexanol was considerably more abundant in the neonate stool compared to adult stool, and probably reflects high exposure to plastic materials containing plasticizers. The potential of disease diagnoses from the analysis of volatiles emitted from neonate faeces is discussed.
Dispersion compensation-free fiber laser mode-locked and stabilized by a high-contrast saturable absorber mirror (2004)

We report here a compact diode-pumped fiber laser that represents a promising route to designing a portable picosecond light source that is rugged and compact. The laser design presented in this paper is based on a high-contrast semiconductor saturable absorber mirror (SESAM) and targets a reliable picosecond-range fiber laser. The cavity is simple, since no dispersion compensators are used, the SESAM-based mode locking mechanism is robust, and self-starting resulted in low-maintenance turn-key operation. We investigated pulse formation in a short-length fiber cavity and found that nonlinear effects in a near-resonant SESAM in combination with the large cavity dispersion are the predominant mechanism that causes self-starting and stabilization of mode-locking. The effect of the recovery time of the SESAM on the stretched-pulse width and spectrum for resonant-type absorber mirrors was also studied.
Word recognition using hidden control neural architecture (2002)

Neural networks are used to model nonlinear and time-varying systems. The proposed model attempts to cope with the time variability systems by adding an undetermined control input which modulates the mapping implemented by the network. The network architecture proposed, the hidden control neural network (HCNN), combines nonlinear prediction of conventional neural networks with hidden Markov modeling. This network is trained using an algorithm that is based on back-propagation and segmentation algorithms for estimating the unknown control together with the network's parameters. The HCNN approach is evaluated on multispeaker recognition of connected digits, yielding a word accuracy of 99.3%.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
