City-Scale Change Detection in Cadastral 3D Models Using Images (2013)

In this paper, we propose a method to detect changes in the geometry of a city using panoramic images captured by a car driving around the city. We designed our approach to account for all the challenges involved in a large scale application of change detection, such as, inaccuracies in the input geometry, errors in the geo-location data of the images, as well as, the limited amount of information due to sparse imagery. We evaluated our approach on an area of 6 square kilometers inside a city, using 3420 images downloaded from Google Street View. These images besides being publicly available, are also a good example of panoramic images captured with a driving vehicle, and hence demonstrating all the possible challenges resulting from such an acquisition. We also quantitatively compared the performance of our approach with respect to a ground truth, as well as to prior work. This evaluation shows that our approach outperforms the current state of the art.
Model-based detection and direction of arrival estimation in radar using sparse arrays (2005)

In this paper we investigate the potential performance of radar systems employing sparse arrays. Different sparse array geometries are evaluated with respect to detection and estimation performance, with particular attention paid to the effect of near-ambiguities on system performance. The results show that sparse arrays have several advantages over a fully populated array, but that the near-ambiguities deteriorate performance when sidelobe interference is present.
Finding the Exhaustive List of Small Fully Absorbing Sets and Designing the Corresponding Low Error-Floor Decoder (2012)

This work provides an efficient exhaustive search algorithm for finding all small fully absorbing sets (FASs) of any arbitrary low-density parity-check (LDPC) code. The proposed algorithm is based on the branch-&-bound principle for solving NP-complete problems. In particular, given any LDPC code, the problem of finding all FASs of size less than t is formulated as an integer programming problem, for which a new branch-&-bound algorithm is devised with new node selection and tree-trimming mechanisms. The resulting algorithm is capable of finding all FASs of size <; 7 for LDPC codes of length <; 1000. When limiting the FASs of interest to those with the number of violated parity-check nodes <; 3, the proposed algorithm is capable of finding all such FASs of size <; 14 for LDPC codes of lengths <; 1000. The resulting exhaustive list of small FASs is then used to devise a new efficient post-processing low-error floor LDPC decoder. The numerical results show that by exploiting the exhaustive list of small FASs, the proposed post-processing decoder can significantly lower the error-floor performance of a given LDPC code. For various example codes of length <; 3000, the proposed post-processing decoder lowers the error floor by a couple of orders of magnitude when compared to the standard belief propagation decoder and by an order of magnitude when compared to other existing low error-floor decoders.
Audio-Visual Based Online Multi-Source Separation (2022)

Meeting or conference assistance is a popular application that typically requires compact configurations of co-located audio and visual sensors. This paper proposes a novel solution for online separation of an unknown and time-varying number of moving sources using only a single microphone array co-located with a single visual device. The approach exploits the complementary nature of simultaneous audio and visual measurements, accomplished by a model-centric 3-stage process of detection, tracking, and (spatial) filtering, which performs separation in a block-wise or recursive fashion. Fusing the measurements requires solving the multi-modal space-time permutation problem, since the audio and visual measurements reside in different observation spaces, but also are unidentified or unlabeled (with respect to the unknown and time-varying number of sources), and are subject to noise, extraneous measurements and missing measurements. A labeled random finite set tracking filter is applied to resolve the permutation problem and recursively estimate the source identities and trajectories. A time-varying set of generalized side-lobe cancellers is constructed based on the tracking estimates to perform online separation. Evaluations are undertaken with live human speakers.

Changes in von Willebrand factor–cleaving protease (ADAMTS13) activity after infusion of desmopressin (2003)

von Willebrand factor-cleaving protease (ADAMTS13) cleaves von Willebrand factor (VWF) and regulates its physiologic function. To investigate the relation between ADAMTS13 activity and VWF, we compared ADAMTS13 activity with the VWF-related parameters VWF antigen (VWF:Ag), VWF collagen-binding activity (VWF:CBA), VWF-propeptide, proVWF, and VWF multimeric composition in 10 healthy volunteers and 3 patients with type 1 von Willebrand disease before and after infusing 0.3 microg/kg desmopressin. The VWF-related parameters in the volunteers increased 60 minutes after start of infusion by 3.7-fold for VWF:Ag, 7.2-fold for propeptide, and 2.2-fold for VWF:CBA. Unusually large VWF multimers and traces of proVWF appeared. The ADAMTS13 activity decreased to about half the initial value. After 24 hours values returned to baseline. Patients with type 1 von Willebrand disease showed similar results. We conclude that the inverse correlation between ADAMTS13 and VWF-related parameters suggests a consumption of ADAMTS13 after the desmopressin-induced release of higher multimers of VWF.
Neutrophil to lymphocyte ratio predicts pattern of recurrence in patients undergoing liver resection for colorectal liver metastasis and thus the overall survival (2014)

Elevated NLR in patients who undergo hepatectomy following neoadjuvant chemotherapy for CRLM increases risk of extrahepatic/multifocal recurrence and is an independent predictor of overall survival.
Effect of an external electric field on the dissociation energy and the electron density properties: The case of the hydrogen bonded dimer HF⋯HF (2009)

The effect of a homogeneous external electric field parallel to the hydrogen bond in the FH...FH dimer has been studied by theoretical methods. The quantum theory of atoms in molecules methodology has been used for analyzing the electron distribution of the dimer, calculated with different hydrogen bond distances and external field magnitudes. It is shown that an electric field in the opposite direction to the dipole moment of the system strengthens the interaction due to a larger mutual polarization between both molecules and increases the covalent character of the hydrogen bond, while an external field in the opposite direction has the inverse effect. The properties of the complex at its equilibrium geometry with applied field have been calculated, showing that dependencies between hydrogen bond distance, dissociation energy, and properties derived from the topological analysis of the electron distribution are analogous to those observed in families of XDH...AY complexes. The application of an external field appears as a useful tool for studying the effect of the atomic environment on the hydrogen bond interaction. In the case of FH...FH, both the kinetic energy density and the curvature of the electron density along the hydrogen bond at the bond critical point present a surprisingly good linear dependence on the dissociation energy. The interaction energy can be modeled by the sum of two exponential terms that depend on both the hydrogen bond distance and the applied electric field. Moreover, as indicated by the resulting interaction energy observed upon application of different external fields, the equilibrium distance varies linearly with the external field, and the dependence of the dissociation energy on either the hydrogen bond distance or the external electric field is demonstrated to be exponential.
Blind prediction of broadband coherence time at basin-scales (2004)

A blind comparison with data is made with a model for the coherence time of broadband sound (133 Hz, 17 Hz bandwidth) at 3709 km. Coherence time is limited by changes in the ocean because the acoustic instruments are fixed to the Earth on the bottom of the sea with time bases maintained by atomic clocks. Although the modeled coherence time depends a bit on the difficult problem of correctly modeling relative signal-to-noise ratios, normalized correlation coefficients of the broadband signals for the data (model) are 0.90 (0.83), 0.72 (0.59), and 0.51 (0.36) at lags of 2, 4.1, and 6.2 mins respectively. In all these cases, observed coherence times are a bit longer than modeled. The temporal evolution of the model is based on the linear dispersion relation for internal waves. Acoustic propagation is modeled with the parabolic approximation and the sound speed insensitive operator.
Synthesis of 35‐Deoxy Amphotericin B Methyl Ester: A Strategy for Molecular Editing (2008)

A modular strategy for the assembly of amphotericin B analogues with modifications in the macrolactone ring relies on the efficient gram-scale synthesis of all major and minor motifs of amphotericin B. Proof of concept has been achieved by the preparation of the 35-deoxy aglycone en route to the long-sought-after 35-deoxy analogue of amphotericin B.
Characterization of an HLA DR beta pseudogene. (1985)

The class II molecules of the human major histocompatibility complex include the DR, DC, and SB antigens, each composed of an alpha and a beta polypeptide chain. We have isolated a DR beta gene in overlapping cosmid clones made from genomic DNA of a Dw4/DR4 homozygous individual. This gene consists of six exons and spans greater than 20 kilobases. Upon sequencing, it was found to possess several deleterious mutations, each capable of rendering the gene nonfunctional: (i) four splice junctions deviate from the G-T/A-G rule; (ii) two premature termination codons are present in the first domain exon; (iii) a 2-base-pair insertion causes a translational frame shift in the second domain exon. In addition, several amino acid residues that are conserved in all known expressed beta chains have been replaced in the amino acid sequence predicted from the pseudogene. Analysis of the pattern of nucleotide substitutions in the second domain exon suggests that most amino acid replacements occurred after the gene was inactivated. The inactivation may have been caused by insertion of a Kpn I repeat 5' to the promoter region, thereby interfering with transcription of the gene through removal of transcriptional enhancer elements. The DR beta pseudogene seems to be present also in other DR4 individuals.
Data-mining patent literature for novel chemical reagents for use in medicinal chemistry design (2010)

The properties of any molecule are fixed at the point of design. Since reliance on commercially available reagents sets to probe SAR relationships may result in incomplete interrogation of property space, efforts to pursue novel proprietary reagent collections are of clear benefit. One such approach based on fragmentation and analysis of molecules described in patent and medicinal chemistry literature is described, highlighting an example of key secondary amines with potential for broad applicability across medicinal chemistry.

A1067. DEVELOPMENT AND INTEGRATION OF ULTRA-WIDEBAND WIRELESS TECHNOLOGY FOR COMPUTER ASSISTED ORTHOPAEDIC SURGERY (2011)

Wireless technologies applied to the medical field have grown both in prevalence and importance in the past decade. Various applications and technologies exist underneath the telemedicine umbrella including Point-of-Care systems where electrocardiographs, blood pressure, temperature, and medical image data are recorded and transmitted wirelessly, which enables remote patient monitoring from inside hospitals, personal residences, and virtually any location with access to satellite communication. Another widespread application for wireless systems in hospitals is asset tracking, typically done with RFID technology. Wireless technologies have not been widely used in computer assisted orthopaedic surgery (CAOS) because of the limitations in terms of overall 3-D accuracy. We have developed a wireless positioning system based on ultra wideband technology (UWB) which achieves mm-range 3-D dynamic accuracy and can be used for intraoperative tracking in CAOS systems. Current intraoperative tracking technologies include optical and electromagnetic tracking systems. The main limitations with these systems include the need for line-of-sight in optical systems and the limited view volume and susceptibility to metallic interference in electromagnetic tracking systems. UWB indoor positioning does not suffer from these effects. Until this point, the main limitation of UWB indoor positioning systems was its limitation in 3-D real-time dynamic accuracy (10–15 cm as opposed to the required 1–2 mm). We have developed a UWB indoor positioning system which achieves dynamic 3-D accuracy in the range of 5–6 mm for a non-coherent approach and 0.5–1 mm for a coherent approach (transmitter and receiver use the same clock signal). The integration of this tracking system with smart surgical tools opens up a plethora of exciting intraoperative applications including picking landmarks, 3-D bone and instrument registration, real-time wireless pressure sensing used for ligament balancing in TKA, and real-time A-mode ultrasound bone morphing. The UWB tracking system will be presented along with its integration into smart surgical tools and surgical navigation.
Brain-based ranking of cognitive domains to predict schizophrenia (2018)

Abstract Schizophrenia is a devastating brain disorder that disturbs sensory perception, motor action, and abstract thought. Its clinical phenotype implies dysfunction of various mental domains, which has motivated a series of theories regarding the underlying pathophysiology. Aiming at a predictive benchmark of a catalogue of cognitive functions, we developed a bottom-up machine-learning strategy and provide a proof of principle in a multi-site clinical dataset (n=324). Existing neuroscientific knowledge on diverse cognitive domains was first condensed into neuro-topographical maps. We then examined how the ensuing meta-analytic cognitive priors can distinguish patients and controls using brain morphology and intrinsic functional connectivity. Some affected cognitive domains supported well-studied directions of research on auditory evaluation and social cognition. However, rarely suspected cognitive domains also emerged as disease-relevant, including self-oriented processing of bodily sensations in gustation and pain. Such algorithmic charting of the cognitive landscape can be used to make targeted recommendations for future mental health research.

Addendum: Fermiology and electron dynamics of trilayer nickelate La4Ni3O10 (2018)

The DFT calculations in the main text use crystal structure information determined by x-ray diffraction (XRD) measurements of La&lt;sub&gt;4&lt;/sub&gt;Ni&lt;sub&gt;3&lt;/sub&gt;O&lt;sub&gt;10&lt;/sub&gt;. The room temperature XRD measurements on all samples were consistent with mixed phases of orthorhombic and monoclinic symmetry. However, the in-plane lattice constants of these two phases differ by &lt;1%, leading to minimal influence on band structure calculations. Furthermore, any impact on the experimental Fermi surface attributable to such deviations would be obscured by broadening of the bands measured by ARPES. Therefore, the DFT calculations adopt the higher symmetry orthorhombic crystal structure with space group Cmca and lattice constants a = 5.417 Å, c = 5.468 Å, b = 27.962 Å, with some additional relaxation of the internal coordinates. The detailed atomic coordinates are presented in Supplementary Table 1.
Mitigating application-level denial of service attacks on Web servers (2008)

Recently, we have seen increasing numbers of denial of service (DoS) attacks against online services and Web applications either for extortion reasons or for impairing and even disabling the competition. These DoS attacks have increasingly targeted the application level. Application-level DoS attacks emulate the same request syntax and network-level traffic characteristics as those of legitimate clients, thereby making the attacks much harder to detect and counter. Moreover, such attacks often target bottleneck resources such as disk bandwidth, database bandwidth, and CPU resources. In this article, we propose handling DoS attacks by using a twofold mechanism. First, we perform admission control to limit the number of concurrent clients served by the online service. Admission control is based on port hiding that renders the online service invisible to unauthorized clients by hiding the port number on which the service accepts incoming requests. Second, we perform congestion control on admitted clients to allocate more resources to good clients. Congestion control is achieved by adaptively setting a client's priority level in response to the client's requests in a way that can incorporate application-level semantics. We present a detailed evaluation of the proposed solution using two sample applications: Apache HTTPD and the TPCW benchmark (running on Apache Tomcat and IBM DB2). Our experiments show that the proposed solution incurs low performance overhead and is resilient to DoS attacks.
Design of heterogeneous ICs for mobile and personal communication systems (1994)

Mobile and personal communication systems form key market areas for the electronics industry of the nineties. Stringent requirements in terms of flexibility, performance and power dissipation, are driving the development of integrated circuits into the direction of heterogeneous single-chip solutions. New IC architectures are emerging which contain the core of a powerful programmable processor, complemented with dedicated hardware, memory and interface structures. In this tutorial we will discuss the real-life design of a heterogeneous IC for an industrial telecom application: a reconfigurable mobile terminal for satellite communication. Based on this practical design experience, we will subsequently discuss a methodology for the design of heterogeneous ICs. Design steps that will be addressed include: system specification and refinement, data path and communication synthesis, and code generation for embedded processor cores.
An Experimental Model of Headache-Related Pain (2012)

Migraine patients often demonstrate cutaneous allodynia, defined as a hypersensitivity of the skin to touch or mechanical stimuli that are normally innocuous. The allodynia sometimes begins intracranially and spreads, via unknown mechanisms, to extracranial regions. The goal of the study was to develop and validate a model of cutaneous allodynia triggered by dural inflammation for this aspect of pain associated with headaches. Inflammatory mediators (IM) were applied to the dura of non-anesthetized rats via previously implanted cannulas and sensory thresholds of the face and hindpaws were characterized. IM elicited robust and time-related facial and hindpaw allodynia which peaked after approximately 3 h. These effects were reminiscent of cutaneous allodynia seen in patients with migraine or other primary headache conditions, and were reversed by agents used clinically in the treatment of migraine. Facial and hindpaw allodynia associated with dural stimulation is a useful surrogate of allodynia associated with primary headache including migraine likely reflecting the development of central sensitization and may be exploited mechanistically for the development of novel therapeutic strategies for headache pain.

Cladosporium Avr2 Inhibits Tomato Rcr3 Protease Required for Cf-2 -Dependent Disease Resistance (2005)

How plants recognize pathogens and activate defense is still mysterious. Direct interaction between pathogen avirulence (Avr) proteins and plant disease resistance proteins is the exception rather than the rule. During infection, Cladosporium fulvum secretes Avr2 protein into the apoplast of tomato leaves and, in the presence of the extracellular leucine-rich repeat receptor-like Cf-2 protein, triggers a hypersensitive response (HR) that also requires the extracellular tomato cysteine protease Rcr3. We show here that Avr2 binds and inhibits Rcr3 and propose that the Rcr3-Avr2 complex enables the Cf-2 protein to activate an HR.
