LIVE: a Tool for Checking Licenses Compatibility between Vocabularies and Data (2014)

Abstract In the Web of Data, licenses specifying the terms of use and reuse are associated not only to datasets but also to vocabularies. However, even less support is provided for taking the licenses of vocabularies into account than for datasets, which says it all. In this paper, we present a framework called LIVE able to support data publishers in verifying licenses compatibility, taking into account both the licenses associated to the vocabularies and those assigned to the data built using such vocabularies. 1
Deep Brain Stimulation of Frontal Lobe Networks to Treat Alzheimer’s Disease (P2.222) (2016)

Objective: The study objective was to evaluate the safety and efficacy of Deep Brain Stimulation (DBS) at the ventral capsule/ventral striatum (VC/VS) region to specifically modulate frontal lobe behavioral and cognitive networks as a novel treatment approach for AD patients. Background: Treatments for Alzheimer’s disease (AD) are limited. Previously published investigations of DBS in AD have only targeted memory circuits. DBS to specifically modulate the frontal networks has never been performed but is a logical treatment approach as deficits in executive abilities, decision-making, and problem solving in AD patients, result in functional impairments and increased supervision needs that are very challenging for caretakers. Methods: This is a non-randomized phase I safety and pilot feasibility prospective open label interventional trial with matched comparison groups. AD participants given DBS for at least 18 months at the VC/VS target were compared on the Clinical Dementia Rating-Sum of Boxes (CDR-SB), our primary outcome clinical measure, to matched groups without DBS from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) cohort. Results: Three AD DBS participants were matched to 13, 95, and 9 subjects respectively from the ADNI AD cohort. All participants tolerated DBS well without significant adverse events. All three AD DBS participants had less performance decline and two of them significantly less decline (p<0.05) after 18-28 months on our primary outcome measure, CDR-SB, relative to matched comparison groups from ADNI using score trajectory slopes. Conclusions: The first use of DBS in AD at a frontal lobe target (VC/VS) revealed preliminary findings of less performance decline in CDR-SB. Frontal network modulation to improve executive and behavioral deficits should be furthered studied in AD.
A Strength Based Approach for the Synthesis of a Compliant Nonlinear Spring for an Orthotic Knee Brace (2013)

Lightweight mechanical energy-storage devices or springs with nonlinear strain-energy absorption rate are important building blocks for passive/quasi-passive rehabilitation robotics. They provide support and controllable energy storage/release into the system thereby making daily activities such as walking/running metabolically efficient for the disabled. These devices have stringent footprint constraints and must withstand 10 million cycles of loading for successful implementation on an orthotic device. Currently, there are no off-the-shelf springs or a systematic synthesis methodology that can meet these requirements in a deterministic fashion. In this paper, we demonstrate how existing body of knowledge in compliant mechanisms can be systematically leveraged to design spring geometries with distributed compliance that meet fatigue criteria and weight requirements. Towards this, we implement a strength-based approach to determine feasible initial solutions that upon optimization yield geometries with maximally distributed stresses. Such a framework is general and can be adapted for designing any compliant mechanism.
Secure Two-Party Computation is Practical. (2009)

Abstract. Secure multi-party computation has been considered by the cryptographic community for a number of years. Until recently it has been a purely theoretical area, with few implementations with which to test various ideas. This has led to a number of optimisations being proposed which are quite restricted in their application. In this paper we describe an implementation of the two-party case, using Yao’s garbled circuits, and present various algorithmic protocol improvements. These optimisations are analysed both theoretically and empirically, using experiments of various adversarial situations. Our experimental data is provided for reasonably large circuits, including one which performs an AES encryption, a problem which we discuss in the context of various possible applications. 1
Field experiment of 10 Gbit/s, 360 km transmissionthrough embedded standard (non-DSF) fibre cables (1994)

The authors have demonstrated, for the first time, 10 Gbit/s transmission over 360 km of embedded standard fibre cables. During the five month long field experiment, the 1.55 µm, 10 Gbit/s IM/DD system showed long term ‘error free’ transmission (less than 10-16 BER) with an optical repeater spacing of 120 km (33 dB repeater span loss).
An Open and Shut Case: The Interaction of Magnesium with MST Enzymes (2016)

The shikimate pathway of bacteria, fungi, and plants generates chorismate, which is drawn into biosynthetic pathways that form aromatic amino acids and other important metabolites, including folates, menaquinone, and siderophores. Many of the pathways initiated at this branch point transform chorismate using an MST enzyme. The MST enzymes (menaquinone, siderophore, and tryptophan biosynthetic enzymes) are structurally homologous and magnesium-dependent, and all perform similar chemical permutations to chorismate by nucleophilic addition (hydroxyl or amine) at the 2-position of the ring, inducing displacement of the 4-hydroxyl. The isomerase enzymes release isochorismate or aminodeoxychorismate as the product, while the synthase enzymes also have lyase activity that displaces pyruvate to form either salicylate or anthranilate. This has led to the hypothesis that the isomerase and lyase activities performed by the MST enzymes are functionally conserved. Here we have developed tailored pre-steady-state approaches to establish the kinetic mechanisms of the isochorismate and salicylate synthase enzymes of siderophore biosynthesis. Our data are centered on the role of magnesium ions, which inhibit the isochorismate synthase enzymes but not the salicylate synthase enzymes. Prior structural data have suggested that binding of the metal ion occludes access or egress of substrates. Our kinetic data indicate that for the production of isochorismate, a high magnesium ion concentration suppresses the rate of release of product, accounting for the observed inhibition and establishing the basis of the ordered-addition kinetic mechanism. Moreover, we show that isochorismate is channeled through the synthase reaction as an intermediate that is retained in the active site by the magnesium ion. Indeed, the lyase-active enzyme has 3 orders of magnitude higher affinity for the isochorismate complex relative to the chorismate complex. Apparent negative-feedback inhibition by ferrous ions is documented at nanomolar concentrations, which is a potentially physiologically relevant mode of regulation for siderophore biosynthesis in vivo.
Wideband Circularly Polarized E-Shaped Patch Antenna for Wireless Applications [Wireless Corner] (2010)

A new technique to achieve a circularly polarized probe-fed single-layer microstrip-patch antenna with a wideband axial ratio is proposed. The antenna is a modified form of the conventional E-shaped patch, used to broaden the impedance bandwidth of a basic patch antenna. By letting the two parallel slots of the E patch be unequal, asymmetry is introduced. This leads to two orthogonal currents on the patch and, hence, circularly polarized fields are excited. The proposed technique exhibits the advantage of the simplicity of the E-shaped patch design, which requires only the slot lengths, widths, and position parameters to be determined. Investigations of the effect of various dimensions of the antenna have been carried out via parametric analysis. Based on these investigations, a design procedure for a circularly polarized E-shaped patch was developed. A prototype has been designed, following the suggested procedure for the IEEE 802.11big WLAN band. The performance of the fabricated antenna was measured and compared with simulation results. Various examples with different substrate thicknesses and material types are presented and compared with the recently proposed circularly polarized U-slot patch antennas.
SKNet: Detecting Rotated Ships as Keypoints in Optical Remote Sensing Images (2021)

Detecting rotated ships is difficult in optical remote sensing images due to the challenges of complex scenes. Existing advanced rotated ship detectors are typically anchor-based algorithms that require plenty of predefined anchors. However, the use of anchors brings three critical problems: 1) a large number of anchors bring a huge amount of calculation; 2) the attributes (e.g., size and aspect ratios) of anchors are designed via <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ad hoc</i> heuristics; and 3) only a tiny fraction of anchors that overlap with ground-truth bounding boxes of ships tightly can be considered as positive samples, which causes an extreme imbalance between positive and negative samples. As a result, the detection accuracy will be influenced seriously when the design of anchors is not suitable. To address the above problems, this article proposes a novel anchor-free rotated ship detection framework, called SKNet, which detects rotated ships as keypoints in optical remote sensing images. In SKNet, a ship target is modeled as its center keypoint and morphological sizes, including the width, height, and rotation angle. Accordingly, we design two customized modules: orthogonal pooling and soft-rotate-nonmaximum suppression (NMS), where the former is to improve the prediction accuracy of the center keypoint and the morphological size, and the latter is to effectively remove redundant rotated ship detection results. Extensive experiments are conducted to demonstrate the effectiveness of SKNet on three optical remote sensing image data sets: HRSC2016, DOTA-ship, and HPDM-OSOD, which is collected by ourselves and published in this article. Empirical studies show that SKNet achieves state-of-the-art detection performance while being time-efficient. Overall, SKNet achieves the best speed–accuracy tradeoff.
Burkholderia cepacia Genomovar III Is a Common Plant-Associated Bacterium (2001)

A polyphasic taxonomic study involving DNA-DNA hybridization, whole-cell protein electrophoresis, and 16S ribosomal DNA sequence analysis revealed that a group of Burkholderia cepacia-like organisms isolated from the rhizosphere or tissues of maize, wheat, and lupine belong to B. cepacia genomovar III, a genomic species associated with "cepacia syndrome" in cystic fibrosis patients. The present study also revealed considerable protein electrophoretic heterogeneity within this species and demonstrated that the B. cepacia complex consists of two independent phylogenetic lineages.

Immunization with SPf66 and subsequent infection with homologous and heterologous Plasmodium falciparum parasites. (1998)

In an area of intense transmission, a malaria vaccine could reduce infection due to the parasite types represented in the vaccine, but have no detectable effect on the overall frequency of infection if it did not protect against infection with heterologous parasites. These studies were performed to determine whether immunization with SPf66 decreased infection with homologous parasites containing the 11 amino acid peptide from merozoite surface protein-1 (MSP-1) in SPf66, or increased infection due to heterologous parasites containing heterologous (alternative) MSP-1 sequences. Based on this 11 amino acid peptide (YSLFQKEKMVL), three forward primers (S,Q,V) were designed to amplify the MSP-1 sequence present in SPf66, and 3 additional forward primers (G,H,I) to amplify the alternative MSP-1 sequence (YGLFHKEKMIL). This strategy was validated by polymerase chain reaction (PCR) amplification and dideoxy sequencing with 14 cloned laboratory isolates, which demonstrated that each primer amplified one MSP-1 sequence or the other, but not both. The technique was then used to examine filter paper blots from an SPf66 vaccine study of 69 subjects in Saradidi, Kenya. In that study, the prevalence of infection with YSLFQKEKMVL or YGLFHKEKMIL type parasites was unaffected by immunization with SPf66 (based on PCR amplification with the S, Q, V, G, H and I primers, respectively). These results suggest that immunization with SPf66 does not produce a selective effect in vivo. They demonstrate a molecular method to test for selection in vivo as an indirect measure of vaccine efficacy.
An 8GHz multi-beam spatio-spectral beamforming receiver using an all-passive discrete time analog baseband in 65nm CMOS (2012)

A novel multi-frequency beamforming front-end is proposed. The proposed front-end allows for simultaneous and independent steering of multiple frequency beams. As proof of concept, an 8GHz 2-channel, 4-frequency phased array beam-former is designed and implemented in 65nm CMOS. The IF signal on each channel is frequency split using an all passive 4-point analog FFT. The orthogonal frequency outputs are then beam steered using an all passive I-Q vector combiner. The RF circuit draws 22.8mA from a 1.2V supply while the analog baseband consumes 9pJ/conv. (135μW at 120MSps).
Effect of interferon alpha on high serum androgen concentrations in HIV positive men with Kaposi's sarcoma. (1997)

AIM: To measure serum androgen concentrations in men with HIV related Kaposi's sarcoma (KS) who had been treated with recombinant interferon (IFN) alpha-2a to determine the role of androgens on the development of KS lesions. METHODS: 32 men with HIV related KS who had been treated with IFN were studied: 24 men in complete KS remission and eight not in remission. Serum androgen concentrations were determined before, during, and after IFN treatment and correlated with clinical remission. RESULTS: All patients in complete KS remission had lower serum androgen concentrations following IFN treatment: -51% for dehydroepiandrosterone (DHEA) (p &lt; 0.0001); -38% for DHEA sulphate (p &lt; 0.002);-39% for androstenedione (p &lt; 0.002); and -44% for testosterone (p &lt; 0.007). These decreases brought the serum concentrations to about normal levels. However, IFN had varying effects on serum androgen concentrations in the men not in remission: a small decrease, a large increase in one androgen, or no change in serum androgens. CONCLUSIONS: The association between serum androgen levels and the progression or remission of HIV associated KS suggests that androgens affect the development of KS lesions. A clear understanding of the changes in the androgen environment may provide a sound basis for the development of new therapeutic strategies.
Possibility of a Mott-Hubbard ground state for the SiC(0001) surface (1998)

The possibility that large electronic correlation effects produce a semiconducting surface-state spectrum for the $\mathrm{Si}{\ensuremath{-}T}_{4}$ adatom model of the $\mathrm{SiC}(0001)\sqrt{3}\ifmmode\times\else\texttimes\fi{}\sqrt{3}$ surface is discussed. We argue that a Hubbard model, with parameters obtained from local-density calculations, provides a qualitatively correct account of the excitation spectra inferred from angle-resolved photoemission and inverse-photoemission experiments. The Hubbard $U$ parameter obtained in local-density-functional calculations for the Si-adatom dangling bond on SiC(0001) is 1.6 eV.
Synthesis of 2-Substituted myo-Inositol 1,3,4,5-Tetrakis(phosphate) and 1,3,4,5,6-Pentakis(phosphate) Analogs (1994)

Abstract Some biologically interesting inositol poly(phosphate) derivatives, 2-O-(p-aminobenzoyl)-myo-inositol 1,3,4,5-tetrakis(phosphate), 2-O-(4-aminocyclohexylcarbonyl)-myo-inositol 1,3,4,5-tetrakis(phosphate), myo-inositol 1,3,4,5,6-pentakis(phosphate), and its 2-substituted analogs, were synthesized. Inositol tetrakis(phosphate) and pentakis(phosphate) affinity columns were also prepared. The inositol 1,3,4,5-tetrakis(phosphate) affinity column was found to be effetive in isolating the binding proteins from bovine cardiac membranes.
Cephalometric Approach to the Occlusal Vertical Dimension Reestablishment (2014)

The occlusal vertical dimension (OVD) refers to the length of the face as determined by the amount of separation of the jaws. Its determination is important for the manufacture of restorations. However, defining the correct occlusal vertical dimension for edentulous patients is one of the most important steps for function and esthetics rehabilitation. Cephalometry is a standardized method of assessing dental and facial proportions and their interrelation. Additionally, cephalometric analysis of the facial vertical dimension can establish an individual pattern for each patient. This analysis should become a permanent part of each patient's record. Hence, this study presented a case report with the use of cephalometry as an auxiliary tool in the rehabilitation of OVD. Clinical relevance showed that cephalometric analysis can be an accurate and convenient instrument to treatment planning and prognostic of oral rehabilitation. The reader should understand the clinical implications of using cephalometry as a tool in the rehabilitation of OVD.
Immunofluorescence studies for myosin, α-actinin and tropomyosin in developing hearts of normal and cardiac lethal mutant Mexican axolotls, Ambystoma mexicanum (1980)

Recessive mutant gene c in axolotl embryos results in an absence of normal heart function. Immunofluorescence studies were done to determine the distributions of myosin, tropomyosin and alpha-actinin in the hearts of normal and mutant siblings. Anti-myosin specifically stains the A bands of myofibrils in normal hearts and reveals a progressive increase in myofibril organization with development. Mutant hearts display less staining for myosin than normal and localization is mainly in amorphous collections. Anti-alpha-actinin stains the Z lines of myofibrils in normal myocytes. Mutant cells also have significant staining for alpha-actinin but show no striations. Antitropomyosin intensely stains the I bands of myofibrils in normal cells; however, there is very little staining for tropomyosin in mutant hearts. Thus, mutant myocardial cells have reduced but significant amounts of actin (Lemanski, Mooseker, Peachey & Iyengar, 1976) and myosin, even though non-filamentous, and substantial amounts of alpha-actinin. The cells appear to contain little tropomyosin.

Are JWST/NIRCam color gradients in the lensed z=2.3 dusty star-forming galaxy El Anzuelo due to central dust attenuation or inside-out galaxy growth? (2023)

Gradients in the mass-to-light ratio of distant galaxies impede our ability to characterize their size and compactness. The long-wavelength filters of $JWST$'s NIRCam offer a significant step forward. For galaxies at Cosmic Noon ($z\sim2$), this regime corresponds to the rest-frame near-infrared, which is less biased towards young stars and captures emission from the bulk of a galaxy's stellar population. We present an initial analysis of an extraordinary lensed dusty star-forming galaxy (DSFG) at $z=2.3$ behind the $El~Gordo$ cluster ($z=0.87$), named $El~Anzuelo$ ("The Fishhook") after its partial Einstein-ring morphology. The FUV-NIR SED suggests an intrinsic star formation rate of $81^{+7}_{-2}~M_\odot~{\rm yr}^{-1}$ and dust attenuation $A_V\approx 1.6$, in line with other DSFGs on the star-forming main sequence. We develop a parametric lens model to reconstruct the source-plane structure of dust imaged by the Atacama Large Millimeter/submillimeter Array, far-UV to optical light from $Hubble$, and near-IR imaging with 8 filters of $JWST$/NIRCam, as part of the Prime Extragalactic Areas for Reionization and Lensing Science (PEARLS) program. The source-plane half-light radius is remarkably consistent from $\sim 1-4.5~μ$m, despite a clear color gradient where the inferred galaxy center is redder than the outskirts. We interpret this to be the result of both a radially-decreasing gradient in attenuation and substantial spatial offsets between UV- and IR-emitting components. A spatial decomposition of the SED reveals modestly suppressed star formation in the inner kiloparsec, which suggests that we are witnessing the early stages of inside-out quenching.
Thioketen‐Synthesen, III1) Umsetzung von Phosphonat‐Carbanionen mit Kohlenstoffdisulfid (1979)

Abstract Die α‐monosubstituierten Phosphonat‐Carbanionen 2 reagieren mit Kohlenstoffdisulfid ( 3 ) über die Primäraddukte 4 zu den 1,1‐Alkendithiolaten 6 , die sich durch Alkylierung, Oxidation, Protonierung sowie Phosgenierung zu den Phosphonoverbindungen 7–11 charakterisieren lassen. Die Dithietanone 11 geben für Thioketene typische Reaktionen. Die α,α‐disubstituierten Phosphonat‐Carbanionen 15 setzen sich mit 3 zu den Salzen 16 um, die wie 4 keinerlei Tendenz zur Thioketen‐Bildung in einer Horner‐Reaktion zeigen. Durch Alkylierung werden aus 16 die phosphonosubstituierten Dithioester 18 zugänglich. Ähnlich entstehen aus 15c und Carbonylsulfid ( 24 ) über das Anion 25 die S ‐(Alkyl)thiosäureester 26 und mit Isocyanaten oder Isothiocyanaten 28 über 29 die Amide bzw. Thioamide 30 . Das Anion 29a gibt in der Wärme mit der Bildung des Alkoxyketenimins 31 das erste Beispiel für die Olefinierung eines Heterokumulens nach Horner.
