Wiki Loves Monuments: Crowdsourcing the Collective Image of the Worldwide Built Heritage (2022)

The wide adoption of digital technologies in the cultural heritage sector has promoted the emergence of new, distributed ways of working, communicating, and investigating cultural products and services. In particular, collaborative online platforms and crowdsourcing mechanisms have been widely adopted in the effort to solicit input from the community and promote engagement. In this work, we provide an extensive analysis of the Wiki Loves Monuments initiative, an annual, international photography contest in which volunteers are invited to take pictures of the built cultural heritage and upload them to Wikimedia Commons. We explore the geographical, temporal, and topical dimensions across the 2010–2021 editions. We first adopt a set of CNN-based artificial systems that allow the learning of deep scene features for various scene recognition tasks, exploring cross-country (dis)similarities. To overcome the rigidity of the framework based on scene descriptors, we train a deep convolutional neural network model to label a photo with its country of origin. The resulting model captures the best representation of a heritage site uploaded in a country, and it allows the domain experts to explore the complexity of cross-national architectural styles. Finally, as a validation step, we explore the link between architectural heritage and intangible cultural values, operationalized using the framework developed within the World Value Survey research program. We observe that cross-country cultural similarities match to a fair extent the interrelations emerging in the architectural domain. We think this study contributes to highlighting the richness and the potential of the Wikimedia data and tools ecosystem to act as a scientific object for art historians, iconologists, and archaeologists.
Unification of Gap Soliton Classes (2005)

We introduce a generalized nonlinear Schrodinger equation valid throughout the photonic gap region for a dielectric nonlinear system with a periodic linear background. The equation is derived using a transfer matrix approach and a local Bloch wave description characterized by a universal dimensionless band-structure parameter �. This single equation provides a unified interpretation and novel insight into three classes of gap solitons. The analytical solutions compare
A Wireless Communications Systems Laboratory Course (2009)

A novel wireless communications systems laboratory course is introduced. The course teaches students how to design, test, and simulate wireless systems using modern instrumentation and computer-aided design (CAD) software. One of the objectives of the course is to help students understand the theoretical concepts behind wireless communication systems through hands-on experiments and to make them more confident both in system design and analysis. The course also aims at increasing the interest of students in engineering and technology. Therefore, laboratory experiments that are complementary to the materials discussed in the theoretical part of the course are designed specifically to incorporate the use of several wireless devices that students probably use extensively in their daily lives. Complementing and expanding upon the materials covered in other communication courses is another merit of this laboratory-based course. Meeting the course requirements also helps students improve their oral presentation and report preparation abilities. The evaluation of the course indicates that most of the objectives are achieved. This paper discusses the experiments designed to teach various wireless communication concepts to the students on a weekly basis, as well as the interesting projects and the other course requirements, which could be replicated by other universities.
Increased Amounts of C4‐Containing Immune Complexes and Inefficient Activation of C3 and the Terminal Complement Pathway in a Patient with Homozygous C2 Deficiency and Systemic Lupus Erythematosus (1990)

Plasma and serum samples from a patient with homozygous C2 deficiency and severe systemic lupus erythematosus who responded with full clinical remission after plasma infusions were examined for immune complexes (IC), C3 activation products, and the terminal complement complex (TCC). Plasma contained large amounts of C4-containing IC but no C3-containing IC or complement activation products. Classical pathway activation in vitro did not lead to C3 activation or TCC formation as seen in normal serum, but a very efficient binding of C1q and C4 was found. No disturbances in alternative pathway activation were observed. The results indicate an impaired formation of C3-containing IC and an inefficient clearance of C4-containing IC, supporting the idea of a causal relationship between the dysfunctional classical pathway, pathophysiology, and clinical manifestations in this patient.
c-Met activation leads to the establishment of a TGFβ-receptor regulatory network in bladder cancer progression (2019)

Abstract Treatment of muscle-invasive bladder cancer remains a major clinical challenge. Aberrant HGF/c-MET upregulation and activation is frequently observed in bladder cancer correlating with cancer progression and invasion. However, the mechanisms underlying HGF/c-MET-mediated invasion in bladder cancer remains unknown. As part of a negative feedback loop SMAD7 binds to SMURF2 targeting the TGFβ receptor for degradation. Under these conditions, SMAD7 acts as a SMURF2 agonist by disrupting the intramolecular interactions within SMURF2. We demonstrate that HGF stimulates TGFβ signalling through c-SRC-mediated phosphorylation of SMURF2 resulting in loss of SMAD7 binding and enhanced SMURF2 C2-HECT interaction, inhibiting SMURF2 and enhancing TGFβ receptor stabilisation. This upregulation of the TGFβ pathway by HGF leads to TGFβ-mediated EMT and invasion. In vivo we show that TGFβ receptor inhibition prevents bladder cancer invasion. Furthermore, we make a rationale for the use of combinatorial TGFβ and MEK inhibitors for treatment of high-grade non-muscle-invasive bladder cancers.
Regular and irregular regimes in binary fluid convection excited by parametric resonance (1996)

The growing interest in the study of time-modulated free convection, started first by Gershuni and Zhukhovitsky @1#, is triggered by unfolding new mechanisms of instability. In such systems as binary liquids @2#, multilayer systems @3#, and nematic liquid crystals @4#, which undergo Hopf bifurcation in the absence of modulation, strong destabilization based on the resonance phenomena can be observed in the presence of modulation @5‐7#. It seems that less attention was paid to the fact that in an extended system with translational and reflection symmetries undergoing Hopf bifurcation, when modulation amplitude
Individual‐specific (idiotypic) T‐B cell interactions regulating the production of anti‐2,4,6‐trinitrophenyl antibody. I. Generation of suppressor T cells and antibody directed against immunocompetent cells (1980)

It is known from several experimental systems that the production of dominant antibody idiotypes may be regulated by anti-idiotypic mechanisms. Our aim has been to test whether the potential for such control also exists in the more typical heterogeneous antibody responses of inbred mice to the trinitrophenyl (TNP) hapten, where dominant idiotypes are not recognized. CBA mice were hyperimmunized to trinitrophenylated keyhole limpet hemocyanin. Serum or lightly fixed spleen cells from these mice were injected into normal syngeneic "recipients". The serum and spleen cells from these recipients were found to have the power to suppress in vitro anti-TNP antibody responses made by further spleen cells from the donor mice. This suppression was specifically directed against the cells of the individual donor animals suggesting idiotype-related regulation.
Coded Elastic Computing (2018)

Cloud providers have recently introduced new offerings whereby spare computing resources are accessible at discounts compared to on-demand computing. Exploiting such opportunity is challenging inasmuch as such resources are accessed with low-priority and therefore can elastically leave (through preemption) and join the computation at any time. In this paper, we design a new technique called coded elastic computing, enabling distributed computations over elastic resources. The proposed technique allows machines to leave the computation without sacrificing the algorithm-level performance, and, at the same time, adaptively reduce the workload at existing machines when new ones join the computation. Leveraging coded redundancy, our approach can achieve similar computational cost as the original (noiseless) method when all machines are present; the cost gracefully increases when machines are preempted and reduces when machines join. The performance of the proposed technique is evaluated on matrix-vector multiplication and linear regression tasks. In experimental validations, it can achieve exactly the same numerical result as the noiseless computation, while reducing the computation time by 46% when compared to non-adaptive coding schemes.
The synthesis of P‐chiral optically pure phosphorothioates, phosphorotrithioates, phosphoroselenothioates, methanephosphonothioates, and methylphenylphosphinothioates (1991)

Abstract Enantiomers of representative alkyl esters of phosphorothioic ( 7 ), phosphorodithioic ( 6 ), phosphorotrithioic ( 11 ), phosphoroselenothioic ( 9 ), methanephosphonothioic ( 28 ), methanephosphonodithioic ( 25 ), and methylphenylphosphinothioic ( 31 ) acids were prepared from corresponding pure diastereoisomers of N‐[R(+) ‐ or S (‐)‐α‐methylbenzyl] phosphamidochalcogenates (e.g. 2 , 3 , 12 , 17 , 23 , 26 , and 30 ) via PN → PX conversion, which has been proved to proceed with full retention of configuration at phosphorus.
Involvement of the Urokinase Kringle Domain in Lipopolysaccharide-Induced Acute Lung Injury (2006)

Urokinase plasminogen activator (uPA) plays a major role in fibrinolytic processes and also can potentiate LPS-induced neutrophil activation through interactions with its kringle domain (KD). To investigate the role of the uPA KD in modulating acute inflammatory processes in vivo, we cloned and then developed Abs to the murine uPA KD. Increased pulmonary expression of uPA and the uPA KD was present in the lungs after LPS exposure. Administration of anti-kringle Abs diminished LPS-induced up-regulation of uPA and uPA KD in the lungs, and also decreased the severity of LPS-induced acute lung injury, as determined by development of lung edema, pulmonary neutrophil accumulation, histology, and lung IL-6, MIP-2, and TNF-alpha cytokine levels. These proinflammatory effects of the uPA KD appeared to be mediated through activation of Akt and NF-kappaB. The present studies indicate that the uPA KD plays a major role in the development of TLR4-mediated acute inflammatory processes, including lung injury. Blockade of the uPA KD may prevent the development or ameliorate the severity of acute lung injury induced through TLR4-dependent mechanisms, such as would occur in the setting of Gram-negative pulmonary or systemic infection.

$High-J_c\;NdBa_2Cu_3O_{7-{\delta}}$ thin films on $SrTiO_3$ (100) substrates prepared by the PLD process (2009)

We report a successful fabrication of (NdBCO) films on (STO) (100) substrates by pulsed laser deposition (PLD) in a relatively wide processing window. Under various oxygen pressures controlled by either 1%/Ar mixture gas or pure gas, strongly c-axis oriented NdBCO films were grown at the substrate temperature in 800 mTorr with 1%/Ar gas and also in 400 and 800 mTorr with pure gas. These samples exhibited values over 90K and values of at 77K in self-field (77K, sf). On the other hand, values over were obtained at the temperature regions of in 800 mTorr with 1%/Ar gas at those of in 800 mTorr with pure gas. Unlike previous reports, resent results support that the PLD processing window for high-Jc NdBCO films is not narrow.
Determination of band profiles in GaN films using hard X-ray photoelectron spectroscopy (2017)

We investigated band-profile control by introducing interlayers between a semiconductor and metal contact layers to improve the electrical properties of GaN-based semiconductor devices. We evaluated the electronic structure of the semiconductor surface and the metal/semiconductor interface by hard X-ray photoelectron spectroscopy. We also performed Monte Carlo simulations using the Boltzmann transport equation under the potential profile obtained using the Poisson equation. The band profile in the semiconductor substrate was then examined by comparing the energy spectra from the simulations with those from the experiments. We obtained good agreement between the two results. The present experimental and theoretical methods allow one to determine the band profile near the surface of a semiconductor as well as that in a metal interface. This approach may become a useful tool in the design and/or evaluation of processing conditions.
Risk of further ulcer complications after an episode of peptic ulcer bleeding (1996)

To identify the risk factors for developing recurrent ulcer complications after recovery from an episode of peptic ulcer bleeding 611 patients admitted with peptic ulcer bleeding were studied. Some 557 (91 per cent) were discharged without operation. A total of 22 patients were lost to follow-up and five were excluded as maintenance H2 blockers were required. Of the remaining 530 patients at risk, 169 (32 per cent) developed another complication (166 bleeding, three perforations) over a median follow-up period of 36 months. Patients with duodenal ulcers at the time of bleeding, previous history of peptic ulcer, previous bleeding, history of dyspepsia longer than 3 months, and a short interval between previous ulcer complications and the index bleed were more likely to develop further complications. Sex, age, smoking, coexisting illness, non-steroidal anti-inflammatory drugs intake and time taken to achieve ulcer healing had no predictive value.
Acellular Urethra Bioscaffold: Decellularization of Whole Urethras for Tissue Engineering Applications (2017)

Patients with stress urinary incontinence mainly suffer from malfunction of the urethra closure mechanism. We established the decellularization of porcine urethras to produce acellular urethra bioscaffolds for future tissue engineering applications, using bioscaffolds or bioscaffold-derived soluble products. Cellular removal was evaluated by H&E, DAPI and DNA quantification. The presence of specific ECM proteins was assessed through immunofluorescence staining and colorimetric assay kits. Human skeletal muscle myoblasts, muscle progenitor cells and adipose-derived stromal vascular fractions were used to evaluate the recellularization of the acellular urethra bioscaffolds. The mechanochemical decellularization system removed ~93% of tissue's DNA, generally preserving ECM's components and microarchitecture. Recellularization was achieved, though methodological advances are required regarding cell seeding strategies and functional assessment. Through microdissection and partial digestion, different urethra ECM-derived coating substrates were formulated (i.e. containing smooth or skeletal muscle ECM) and used to culture MPCs in vitro. The skeletal muscle ECM substrates enhanced fiber formation leading to the expression of the main skeletal muscle-related proteins and genes, as confirmed by immunofluorescence and RT-qPCR. The described methodology produced a urethra bioscaffold that retained vital ECM proteins and was liable to cell repopulation, a crucial first step towards the generation of urethra bioscaffold-based Tissue Engineering products.
SEISMIC PERFORMANCE OF UNBONDED POST-TENSIONED PRECAST CONCRETE BEAM-COLUMN CONNECTION (2009)

The aim of this study is to investigate the seismic behavior of the unbonded post-tensioned precast concrete beam-column connections with and without shear bracket under simultaneous action of cyclic load and gravity load. Three specimens of precast unbonded post-tensioned exterior beam-column connection were designed and tested. The test results of the specimen without shear bracket showed excessive beam slip, and large residual deformation. The specimens with shear bracket expressed very good performance with small residual deformation, almost no slip, fully developed strength, minor damage to the beam and column elements, and easy to disassemble. It is concluded that satisfactory seismic performance can be expected from well-designed connection with shear bracket.
Carbon Support Effects on Bimetallic Pt−Ru Nanoparticles Formed from Molecular Precursors (1999)

We describe the preparation, structural characterization, and support interactions experienced by two different compositions of Pt−Ru nanoparticles supported on several carbons (carbon black, fullerene soot, and desulfurized carbon black). The bimetallic nanoparticles, obtained by reduction of the neutral molecular precursors PtRu5C(CO)16 and Pt2Ru4(CO)18 (the latter of which lacks a central “stabilizing” carbide core) at elevated temperatures in a hydrogen atmosphere, show a structural homology, exhibiting exceptionally narrow size and compositional distributions. A detailed structural picture of the nanoparticles has been deduced on the basis of in-situ extended X-ray absorption fine structure (EXAFS), scanning transmission electron microscopy (STEM), energy-dispersive X-ray analysis (EDX), and X-ray absorption near edge structure (XANES). These techniques reveal that the bimetallic nanoparticles have Pt/Ru compositions of 1:5 and 2:4, respectively, and average diameters lying between 1.0 and 1.5 nm. The local metal coordination environments reveal a nonstatistical distribution of the two metals in the nanoparticles. Specifically, Pt shows a marked preference for segregation to the particle surfaces under an H2 atmosphere. The data also reveal a difference in the structural environment of the nanoparticles when formed on the fullerene soot support. Interactions between Ru and low-Z atoms are revealed through XANES, which, taken collectively with the other data presented, leads us to propose a possible Ru−C compound formation on this latter support phase.
Brain Abscess in a Japanese Black Calf: Utility of Computed Tomography (CT) (2008)

Computed tomography (CT) was used for diagnosis of brain abscess in a 6-month-old, Japanese black calf presented with neurological dysfunction, compulsive circling and vision disturbance. CT images showed asymmetric lateral ventricles, and presence of intra-cranial multiple low absorption lesions surrounded by capsule suggestive of abscess in the right cerebral hemisphere. Postmortem examination revealed marked swelling of right cerebral hemisphere and olfactory bulb. Multilocular large abscess containing creamy pus was found to occupy most area of periventricular and lateral ventricle. Fusobacterium necrophrum was isolated from the abscess contents as the causative agent. These results demonstrate that CT is useful tool for tentative diagnosis of bovine brain abscess.
Broadband lightweight flat lenses for long-wave infrared imaging (2019)

Significance We demonstrate, with simulations corroborated by experiments, that broadband long-wave infrared (LWIR) imaging is possible with a single flat lens with a thickness of 10 μm and a weight that is over 100 times less than conventional refractive optics. Reducing the weight and thickness of LWIR optics is crucial for increasing the range of camera-carrying drones as well as for reducing head and neck injuries among camera-borne soldiers. The technology discussed herein will be extremely useful not only to optics specialists but also to camera designers and users in general.

Non-HLA Antibodies to Immunogenic Epitopes Predict the Evolution of Chronic Renal Allograft Injury (2012)

Chronic allograft injury (CAI) results from a humoral response to mismatches in immunogenic epitopes between the donor and recipient. Although alloantibodies against HLA antigens contribute to the pathogenesis of CAI, alloantibodies against non-HLA antigens likely contribute as well. Here, we used high-density protein arrays to identify non-HLA antibodies in CAI and subsequently validated a subset in a cohort of 172 serum samples collected serially post-transplantation. There were 38 de novo non-HLA antibodies that significantly associated with the development of CAI (P<0.01) on protocol post-transplant biopsies, with enrichment of their corresponding antigens in the renal cortex. Baseline levels of preformed antibodies to MIG (also called CXCL9), ITAC (also called CXCL11), IFN-γ, and glial-derived neurotrophic factor positively correlated with histologic injury at 24 months. Measuring levels of these four antibodies could help clinicians predict the development of CAI with >80% sensitivity and 100% specificity. In conclusion, pretransplant serum levels of a defined panel of alloantibodies targeting non-HLA immunogenic antigens associate with histologic CAI in the post-transplant period. Validation in a larger, prospective transplant cohort may lead to a noninvasive method to predict and monitor for CAI.
Polarization Dependent Loss Compensation with Mueller Matrix Monitor in Coherent Transmission System (2018)

We demonstrate a new proposal of polarization-dependent-loss compensation with digital-signal-processing based on Mueller matrix monitor technology. The experimental results show high Q improvement of 1.6dB for a polarization-dependent-loss of 5dB.
Adiabatically tapered slab-coupled optical waveguide lasers (2012)

Adiabatically flared slab-coupled optical waveguide lasers (SCOWLs) at 1.06 μm wavelength have been studied, achieving a large fundamental mode and a 32% increase in COD power. Capabilities and limitations of the taper mechanism are discussed.
