Graph Similarity based on Graph Fourier Distances (2018)

Graph theory is a branch of mathematics which is gaining momentum in the signal processing community due to their ability to efficiently represent data defined on irregular domains. Quantifying the similarity between two different graphs is a crucial operation in many applications involving graphs, such as pattern recognition or social networks' analysis. This paper focuses on the graph similarity problem from the emerging graph Fourier domain, leveraging the spectral decomposition of the Laplacian matrices. In particular, we focus on the intuition that similar graphs should provide similar frequency representation for a particular graph signal. Similarly, we argue that the frequency responses of a particular graph filter applied to two similar graphs should be also similar. Supporting results based on numerical simulations support the aforementioned hypothesis and show that the proposed graph distances provide a new tool for comparing graphs in the frequency domain.
[Antitumor activity and toxicity of KB-5424 R, a newly developed antitumor platinum compound]. (1991)

KB-5424 (ab-(3-aminopyrrolidine)-cd-[glycolato (2-)-0, 0'] platinum (II) is a newly developed antitumor platinum compound which was synthesized at Kanebo Institute for Cancer Research. When the antitumor activity of KB-5424 was evaluated using several rodent tumors, no significant differences were observed between the antitumor activities of KB-5424, cisplatin (CDDP) and DWA-2114 R (DWA). KB-5424 was divided into two kinds of optical isomers, KB-5424 R and KB-5424 S, of which antitumor activity was compared each other. The maximum increased life span (ILSmax) on L 1210 of KB-5424 R was almost equal to that of CDDP and better than those of KB-5424 S and carboplatin (CBDCA). The antitumor activity of KB-5424 R on a human tumor xenograft MX-1 was almost identical to those of CDDP and CBDCA and better than that of DWA. Since the nephrotoxicity of KB-5424 R was significantly reduced comparing with CDDP, this newly developed antitumor platinum compound was thought to be a promising agent for the clinical application.
An Aluminosilicate Zeolite Containing Rings of Tetrahedral Atoms with All Odd Numbers from Five to Eleven (2020)

Herein we report the synthesis, structure solution, and catalytic properties of PST-31, which has an unprecedented framework topology. This high-silica (Si/Al=16) zeolite was synthesized using a pyrazolium-based dication with a tetramethylene linker as an organic structure-directing agent (OSDA) in hydroxide media. The PST-31 structure is built from new building layers containing four-, five-, six-, and seven-membered rings, which are connected by single four-membered rings in the interlayer region to form a two-dimensional pore system. Its channels consist of [4.5<sup>6</sup> .6.9.11] and [5.6.7.9.10.11] cavities and are thus delimited by nine-, ten-, and eleven-membered rings. The OSDA cations in as-synthesized PST-31 were determined to reside without disorder in the large [4<sup>2</sup> .5<sup>14</sup> .6<sup>4</sup> .7<sup>2</sup> .9<sup>4</sup> ] cavities composed of smaller [4.5<sup>6</sup> .6.9.11] and [5.6.7.9.10.11] ones, leading to a symmetry coincidence between the OSDA and the surrounding zeolite cavity. The proton form of PST-31 was found to be selective for the cracking of n-hexane to light olefins.

Synthesis of chiral molecules from non-chiral crystals by controlled reaction at a single surface (1986)

A procedure is described for performing reactions at a single face of a single crystal of organic compounds, using as examples the cis-dihydroxylation of tiglic and crotonic acids by osmium tetraoxide, and the dibromination of tiglic acid. For molecules whose orientation in the crystalline state is appropriate, reactions carried out in this way can produce enantiomerically enriched products from a non-chiral crystal and reagent. Enantiomeric excesses are dependent upon the crystal quality; values up to 30% have been achieved in the reactions of tiglic acid with osmium tetraoxide or bromine vapour.
New and Old Functions of STAT3: A Pivitol Target for Individualized Treatment of Cancer (2005)

Signal transducers and activators of transcription (STAT) regulate a plethora of cytokine responses. Recently, aberrant signaling by STAT proteins has been demonstrated to play important roles in the pathogenesis of many neoplasms, by promoting cell cycle progression and survival, stimulating angiogenesis, and impairing immunological responses and tumor surveillance. We have developed genetic tools to evaluate STAT-dependent malignancy and showed that survival and growth of lymphoid malignancies requires expression of STAT3. In contrast, loss of STAT3 in normal cells does not impair their growth or survival; but in spite of this apparent dispensability of STAT3, STAT3-null fibroblasts are resistant to transformation by a variety of oncogenes. The precise molecular mechanisms responsible for the tumorigenic activity of STAT3 have been only partially elucidated. While the tyrosine phosphorylation of STAT3, which is indicative of its signal-dependent activation, is a common occurrence in tumors, and appears to play a crucial role in some malignancies, a variety of new data suggest that it can be dispensable under some circumstances and STAT3 can participate in transformation through novel and non-canonical mechanisms. The discovery and dissection of non-canonical modes of STAT3 action will open new avenues for the design of effective therapeutics capable of neutralizing the tumorigenic properties of this molecule.
Enhancement of Torque Pulsation and Acoustic Response in SRM Drives via Bipolar Excitation (2005)

&lt;div class="htmlview paragraph"&gt;&lt;b&gt;This paper reports on the analytical and experimental results for an 8/6 switched reluctance machine operating under conventional and bipolar excitation strategies. The results illustrate the relationship between normal and tangential flux densities present in the airgap, and normal and tangential force densities present on stator and rotor poles. The investigation utilizes finite element analysis in conjunction with the Maxwell Stress Tensor method to correlate the relationship between the radial and tangential force densities and the airgap flux densities. In addition, finite element analysis is utilized to illuminate the difference in flux path type between the conventional and bipolar excitation methods. The experimental results are presented in terms of electromagnetic torque production over a full electrical cycle for each excitation method. The enhancement in mitigating torque ripple has a direct correspondence to the acoustic response due the improved magnetic balance that bipolar excitation provides.&lt;/b&gt;&lt;/div&gt;

Characterization of switchable terahertz metasurfaces (2016)

We describe experimental characterization of switchable THz metasurfaces using variable-angle broadband THz ellipsometry. A theoretical framework is used to extract surface susceptibility tensors as a function of frequency and applied DC bias. This will allow us to make a priori predictions of the performance of these devices for applications as metasurface active components.
“Ó cóleras sagradas!/ Dai-me versos febris, agudos como espadas”: a sátira na poesia de Guerra Junqueiro (2022)

The aim of this paper is to determine and understand the ideas and poetics of the Portuguese writer Guerra Junqueiro’s (1850-1923) satire in verse. the article analyzes the literary content, form and stylistic strategies and takes into account Junqueiro’s historical, cultural and literary contexts. the idea of homeland fuels his satire to ridicule and punish both the internal agents that the poet considers responsible for the civilizational backwardness of his country (monarchists, King D. Carlos, the Church, the literati, etc.), and the external ones (England and its Portugal-related policies). the article demonstrates that Junqueiro’s satire is aimed to produce psychological and physical pain, which is metaphorized in the images of defense and punishment. Finally, it proves that this kind of fi gurative violence, in the context of a country in dire need of activism, paradoxically took the form of a nihilistic perspective expressed through a satirical verbalization that can, nonetheless, be considered as “active pessimism”.
Observation of the $B^0_s \to X(3872)\phi$ decay (2020)

Using a data sample of proton-proton collisions at s=13 TeV, corresponding to an integrated luminosity of 140 fb-1 collected by the CMS experiment in 2016–2018, the Bs0→X(3872)ϕ decay is observed. Decays into J/ψπ+π− and K+K- are used to reconstruct, respectively, the X(3872) and ϕ. The ratio of the product of branching fractions B[Bs0→X(3872)ϕ]B[X(3872)→J/ψπ+π−] to the product B[Bs0→ψ(2S)ϕ]B[ψ(2S)→J/ψπ+π−] is measured to be [2.21±0.29(stat)±0.17(syst)]%. The ratio B[Bs0→X(3872)ϕ]/B[B0→X(3872)K0] is found to be consistent with one, while the ratio B[Bs0→X(3872)ϕ]/B[B+→X(3872)K+] is two times smaller. This suggests a difference in the production dynamics of the X(3872) in B0 and Bs0 meson decays compared to B+. The reported observation may shed new light on the nature of the X(3872) particle.
Isolating Stem Cells from Soft Musculoskeletal Tissues (2010)

Adult stem cells have long been discussed in regards to their application in regenerative medicine. Adult stem cells have generated a great deal of excitement for treating injured and diseased tissues due to their impressive capabilities to undergo multi-lineage cell differentiation and their self-renewal ability. Most importantly, these qualities have made them advantageous for use in autologous cell transplantation therapies. The current protocol will introduce the readers to the modified preplate technique where soft tissues of the musculoskeletal system, e.g. tendon and muscle, are 1(st) enzymatically dissociated and then placed in collagen coated flasks with medium. The supernatant, which is composed of medium and the remaining floating cells, is serially transferred daily to new flasks. The stem cells are the slowest to adhere to the flasks which is usually takes 5-7 days (serial transfers or preplates). By using this technique, adult stem cells present in these tissues can be easily harvested through fairly non-invasive procedures.
Aging‐related anatomical and biochemical changes in lymphatic collectors impair lymph transport, fluid homeostasis, and pathogen clearance (2015)

The role of lymphatic vessels is to transport fluid, soluble molecules, and immune cells to the draining lymph nodes. Here, we analyze how the aging process affects the functionality of the lymphatic collectors and the dynamics of lymph flow. Ultrastructural, biochemical, and proteomic analysis indicates a loss of matrix proteins, and smooth muscle cells in aged collectors resulting in a decrease in contraction frequency, systolic lymph flow velocity, and pumping activity, as measured in vivo in lymphatic collectors. Functionally, this impairment also translated into a reduced ability for in vivo bacterial transport as determined by time-lapse microscopy. Ultrastructural and proteomic analysis also indicates a decrease in the thickness of the endothelial cell glycocalyx and loss of gap junction proteins in aged lymph collectors. Redox proteomic analysis mapped an aging-related increase in the glycation and carboxylation of lymphatic's endothelial cell and matrix proteins. Functionally, these modifications translate into apparent hyperpermeability of the lymphatics with pathogen escaping from the collectors into the surrounding tissue and a decreased ability to control tissue fluid homeostasis. Altogether, our data provide a mechanistic analysis of how the anatomical and biochemical changes, occurring in aged lymphatic vessels, compromise lymph flow, tissue fluid homeostasis, and pathogen transport.
Role of CXCR3 in the Immune Response to Murine Gammaherpesvirus 68 (2005)

The chemokine IP-10 (CXCL10) and its cellular receptor CXCR3 are upregulated in the lung during murine gammaherpesvirus 68 (MHV-68) infection. In order to determine the role of the CXCR3 chemokine receptor in the immune response to MHV-68, CXCR3-/- mice were infected with the virus. CXCR3-/- mice showed delayed clearance of replicating MHV-68 from the lungs. This correlated with delayed T-cell recruitment to the lungs and reduced cytolytic activity prior to viral clearance. Splenomegaly and the numbers of latently infected cells per spleen were transiently increased. However, CXCR3-/- mice showed normal virus-specific antibody titers and effective long-term control of MHV-68 infection.
Evaluation of a Novel Manganese-Based Contrast Agent for Cardiac MRI in the Setting of Myocardial Ischemia-Reperfusion (2023)

Cardiac MRI a powerful imaging modality to assess cardiac anatomy and function, and its utility can be greatly enhanced with the use of contrast agents. Conventional contrast agents are nephrotoxic which limits their utility. We evaluate a novel contrast agent which is safe for use in renal dysfunction. We compare its performance against that of a conventional agent a porcine model of ischemia-reperfusion. This novel contrast agent demonstrates equivalent performance in assessing myocardial fibrotic scars, indicating its potential clinical use in the workout of cardiac patients with renal impairment.
A Fuzzy Evidential Reasoning Data Fusion Approach with Uncertainty Evaluation for Robust Pattern Classification (2006)

This paper presents a data fusion approach for pattern classification, based on the fuzzy evidential reasoning technique. First, a new fuzzy evidence structure model is introduced to formulate probabilistic evidence and fuzzy evidence in a unified manner. A generalized Dempster's rule is then used to combine fuzzy evidence structures associated with multiple information sources. Finally, an effective decision rule is developed to take into account uncertainty, quantified by Shannon entropy and fuzzy entropy, of probabilistic evidence and fuzzy evidence, to deal with conflict and to achieve robust decisions. To demonstrate the effectiveness of this approach, we apply it to classify multimodality human brain MR images in a supervised manner. The proposed approach outperforms both the traditional evidential reasoning technique and the fuzzy reasoning technique, in terms of robustness and classification accuracy.
Amino-terminal sequence of the Tn3 transposase protein (1982)

The amino-terminal sequence of the Tn3 transposase protein was determined to be Pro-Val-Asp-Phe-Leu-Thr-Thr-Glu-Gln-Val-Glu-Ser.... This was determined both from an active transposase protein purified from a transposase overproducing mutant strain and from a hybrid transposase-beta-galactosidase fusion protein. The amino acid sequence corresponded to the DNA sequence of the transposase gene beginning at an ATG initiation codon, as previously predicted from the analysis of transposase-beta-galactosidase gene fusions.
Design and operation of a tunable MeV-level Compton-scattering-basedγ-ray source (2010)

A monoenergetic gamma-ray (MEGa-ray) source based on Compton scattering, targeting nuclear physics applications such as nuclear resonance fluorescence, has been constructed and commissioned at Lawrence Livermore National Laboratory. In this paper, the overall architecture of the system, as well as some of the design decisions (such as laser pulse lengths and interaction geometry) made in the development of the source, are discussed. The performances of the two laser systems (one for electron production, one for scattering), the electron photoinjector, and the linear accelerator are also detailed, and initial $\ensuremath{\gamma}$-ray results are presented.
Overall design of 4th Generation Wireless Infrastructures (4GW) (2002)

An important factor contributing to this uncertainty is that we have very limited knowledge about the future environment in which a fourth generation wireless infrastructure should function. Which of today's systems will still exist when a potential 4G infrastructure is deployed? Which systems and solutions will be considered successful then? What technical bottlenecks will be apparent ten years from now? What market impact will third generation wireless systems have? How will this affect user behavior, and user demands? How much money do prospective users have available to pay for services provided over this infrastructure? This paper presents some of the conclusion of of the Fourth Generation Wireless Infrastructure project (4GW) of the Computing and Communications program (PCC), the major Swedish academic research effort on future communications systems launched in late 1997(1). The vision of the PCC project has been Personal Multimedia to everyone at today's prices for fixed telephony. In 4GW a scenario-based approach has been used to tackle the issue of identifying reasonable research topics. In the paper we will present this method, and demonstrate how it interfaces with traditional research methods in the fields that the 4GW project incorporates. We will also give an overview of some research results from the project. Finally, we will conclude these results as a vision of what fourth generation wireless infrastructures might become
Detection of bovine viral diarrhea virus in semen obtained after inoculation of seronegative postpubertal bulls (2003)

Spectroscopic trace gas detection with pulsed quantum cascade lasers (2002)

Pulsed quantum cascade lasers operating at wavelength of 10 and 4.6 microns were used for detection of ammonia and carbon monoxide, respectively. Variations of atmospheric CO concentration were continuously monitored with 12 ppbv precision using a 1 m optical pathlength.
Influence of manufacturing process on electrical properties of LDPE-GnP nanocomposites (2017)

In this report electrical properties of the nanocomposite samples, prepared from graphene nanoplatelet (GnP) loaded low density polyethylene (LDPE) by extrusion and compression molding, were examined in order to elucidate the impacts of the nanoplatelets size and material’s manufacturing process. It is shown that the extrusion forces a strong anisotropy in material’s morphology. The graphene nanoplatelets become aligned along the flow direction. As compared to pure LDPE, a significant reductions of the through-plane low field electric conductivity is found in such samples. On the other hand, the samples produced by press molding exhibit slightly higher level of electric conductivity, which is connected to their less aligned microstructure and filler dispersion. For comparison results of measurements on LDPE-graphene monolayer sandwiches are also presented.
Mammalian Cell Viability in Electrospun Composite Nanofiber Structures (2011)

Incorporation of mammalian cells into nanofibers (cell electrospinning) and multilayered cell-nanofiber structures (cell layering) via electrospinning are promising techniques for tissue engineering applications. We investigate the viability of 3T3-L1 mouse fibroblasts after incorporation into poly(vinyl alcohol) nanofibers and multilayering with poly(caprolactone) nanofibers and analyze the possible factors that affect cell viability. We observe that cells do not survive cell electrospinning but survive cell layering. Assessing the factors involved in cell electrospinning, we find that dehydration and fiber stretching are the main causes of cell death. In cell layering, the choice of solvent is critical, as residual solvent in the electrospun fibers could be detrimental to the cells.
Nordic research in ophthalmology (2003)

Eye research is very active in the Nordic countries and significant contributions are being made to ophthalmology in several fields on a world scale. We hope to continue to review Nordic contributions to eye research after each Nordic Congress of Ophthalmology and plan to make the reviews more systematic and comprehensive in the future.
Thyroglobulin: Evidence for Crystallization and Association (1966)

Crystals of thyroglobulin have been obtained from ammonium sulfate solutions and have been examined by electron microscopy as shadowed carbon replicas. Unit size in the crystal is 228 +/- 9 angstroms, which corresponds to a molecular weight of 5,300,000. Data are in accord with the possibility that this unit represents a polymer of thyroglobulin.
A model for interlevel coupling noise in multilevel interconnect structures (2001)

In multilevel interconnect structures, the interconnect layers are practically always perpendicular to each other. Because of the capacitive coupling between adjacent layers, the switching activity in one layer produces noise in the other. This paper analyses the interlevel coupling noise present at the far end of a victim line when a large number of perpendicular attackers are randomly switching. Each attacker is modeled as a Markov chain and the victim is modeled as an RLC transmission line. The result is a novel closed-form expression for the power spectral density of the interlevel coupling noise.
