Chemical Synthesis and Magnetic Properties of Monodisperse Nickel Ferrite Nanoparticles for Biomedical Applications (2016)

With the aim of improving the response in magnetic hyperthermia treatments and other biomedical applications, a nanoparticle system based on nickel ferrites has been investigated. Monodisperse ferrite nanoparticles with different proportions of Ni2+ ions and sizes have been produced by an optimized synthesis based on the thermal decomposition method and the seed-growth technique. All samples were chemically and structurally characterized by different methods, and the magnetic behavior has been analyzed by means of field and temperature dependent magnetization measurements and electronic magnetic resonance. It has been proved that low proportions of Ni2+ cation in the structure favors high saturation magnetization values and a reduction of the magnetic anisotropy constant. The optimized nanoparticles were transferred to water. Such nanoparticles are innocuous at concentrations up to 0.5 mg/mL and are convenient MRI contrast agents. Those samples with lower percentages of Ni2+ atoms and bigger particle sizes presented the highest specific absorption rate, and, for instance, they are the most adequate for magnetic hyperthermia applications.
LDRD final report on polyphosphaacetylenes, new hybrid conducting organic-inorganic materials (1996)

Thermal, electrochemical and transition metal mediated reactions of phosphaacetylene monomers were conducted in attempts to form novel polyphosphaacetylenes as a new class of potentially electrically conducting polymers. Molecular modeling was used to simulate the molecular conformations of optimized, isolated oligomers to identify the proper monomeric repeat units for highly conjugated molecules. Electrodeposition of suitable monomers led to low molecular weight oligomers. Thermal polymerization of phosphaacetylene monomers bearing aromatic substituents ed to the formation of polyhedral cage oligomers. Under metathesis polymerization conditions the phosphaacetylene monomers form unique complexes via an unprecedented sequence of intermediates which suggest that metathesis to linear oligomers is achievable. Conductivity measurements on electrodeposited oligomers indicate modest electrical conductivity.
Hollow Core Inhibited Coupled Antiresonant Terahertz Fiber: A Numerical and Experimental Study (2020)

In this article, a hollow core antiresonant photonic crystal fiber is analyzed for terahertz applications. A numerical analysis of the proposed fiber is first carried out to minimize coupling between the core and cladding modes. The modeling of the scaled-up and inhibited coupling fiber is carried out by means of a finite element method, which is then demonstrated using a Zeonex filament fiber, fabricated by fused deposition modeling of 3-D printing technology. The simulation is carried out to analyze both the transmission and possibility of refractometric sensing, whereas the experimental analysis is carried out using terahertz time-domain spectroscopy, and supports our numerical findings, illustrating how the proposed fibers can be used for low-loss transmission of terahertz waves. The simplicity of the proposed fiber structures facilitates fabrication for a number of different transmission and sensing applications in the terahertz range.
3D FS LASER WRITING OF QUANTUM DOT AND METALLIC NANOSTRUCTURES (2012)

Diffusion-assisted direct laser writing is a nonlinear optical technique which allows the fabrication of three-dimensional structures with a resolution beyond the diffraction limit. The polymerization process is initiated when the beam of an ultra-fast infrared laser is tightly focused into the volume of a transparent, photosensitive material. Multi-photon absorption takes place within the focal volume, where polymerization occurs due to radical generation. The polymerization voxel can be efficiently reduced by diffusing quenchers. By moving the focused laser beam in a three-dimensional manner within the resin, 3D structures can be fabricated. The technique has been employed successfully in the fabrication of nanophotonic structures and devices.

The RNS System: responsive cortical stimulation for the treatment of refractory partial epilepsy (2014)

The RNS(®) System is the first commercially available device to provide closed-loop responsive brain stimulation. The system includes a cranially implanted neurostimulator that continually monitors the electrocorticogram through one or two depth and/or subdural cortical strip leads that are placed at the seizure focus. When abnormal electrographic activity is detected, the neurostimulator delivers brief pulses of electrical stimulation to the seizure focus through the implanted leads. In November 2013, the US FDA approved the RNS System as an adjunctive therapy for patients with drug resistant, partial onset seizures who have undergone diagnostic testing that localized no more than 2 epileptogenic foci. Safety and effectiveness of the RNS System for the indicated patient population was demonstrated in a multicenter, randomized, sham-stimulation controlled 2-year pivotal study. An ongoing, prospective, long-term treatment study is currently gathering an additional 7 years of prospective safety and effectiveness data of the RNS System.

Asymmetric Synthesis of Protected Arylglycines by Rhodium-Catalyzed Addition of Arylboronic Acids to <i>N</i>-<i>tert</i>-Butanesulfinyl Imino Esters (2006)

A new method for the Rh(I)-catalyzed addition of arylboronic acids to N-tert-butanesulfinyl imino esters has been developed for the asymmetric synthesis of arylglycine derivatives. This method provides high yields (61-90%) and diastereoselectivities (>98:2) for a variety of functionalized arylboronic acids. The N-sulfinyl arylglycine ester products are versatile intermediates for further transformations, including selective protecting group removal, conversion to beta-amino alcohols, and direct incorporation into peptides.
Handling Spontaneous Traffic Variations in 5G+ via Offloading onto\n mmWave-Capable UAV `Bridges' (2020)

Unmanned aerial vehicles (UAVs) are increasingly employed for numerous public\nand civil applications, such as goods delivery, medicine, surveillance, and\ntelecommunications. For the latter, UAVs with onboard communication equipment\nmay help temporarily offload traffic onto the neighboring cells in\nfifth-generation networks and beyond (5G+). In this paper, we propose and\nevaluate the use of UAVs traveling over the area of interest to relieve\ncongestion in 5G+ systems under spontaneous traffic fluctuations. To this end,\nwe assess two inherently different offloading schemes, named routed and\ncontrolled UAV `bridging'. Using the tools of renewal theory and stochastic\ngeometry, we analytically characterize these schemes in terms of the fraction\nof traffic demand that can be offloaded onto the UAV `bridge' as our parameter\nof interest. This framework accounts for the unique features of millimeter-wave\n(mmWave) radio propagation and city deployment types with potential\nline-of-sight (LoS) link blockage by buildings. We also introduce enhancements\nto the proposed schemes that significantly improve the offloading gains. Our\nfindings offer evidence that the UAV `bridges' may be used for efficient\ntraffic offloading in various urban scenarios.\n

Catalytic Enantioselective Synthesis of Amino Skipped Diynes (2016)

The Cu-catalyzed synthesis of nonracemic 3-amino skipped diynes via an enantiodetermining C-C bond formation is described using StackPhos as ligand. Despite challenging issues of reactivity and stereoselectivity inherent to these chiral skipped diynes, the reaction tolerates an extremely broad substrate scope with respect to all components and provides the title compounds in excellent enantiomeric excess. The alkyne moieties are demonstrated here to be useful synthetic handles, and 3-amino skipped diynes are convenient building blocks for enantioselective synthesis.
PE1018, a novel insecticidal compound produced by Humicola sp. (1994)

A new insecticidal compound PF1018 was isolated from the culture broth of Humicola sp. It exhibited insecticidal activity against a wide range of critical pest species. The structure of PF1018 was determined to be (7aS)-2-((2E)-1-hydroxy-3-((1S,3aR,4R,5R,7aR)-3a,4,5,7 a-tetrahydro-1,3,5,7- tetramethyl-5,1-((3S)-(Z)-2,3-dimethylpropeno)-1H-inden-4-yl )-2- propenylidene)pyrrolizidine-1,3-dione, by NMR spectral analyses coupled with X-ray crystallographic analysis and chemical degradation study.
Screening Entire Health System ECG Databases to Identify Patients at Increased Risk of Death (2013)

Screening hospital ECG databases with QRS-scoring and QRS-T angle analysis identifies patients with high 1-year all-cause mortality and predominantly preserved left ventricular ejection fraction. This approach may represent a widely available method to identify patients at increased risk of death.
Indoor exclusion zone analysis in a nuclear power plant with wirelessHART application (2019)

This article investigates the radiation properties of the wireless devices in nuclear power plants (NPPs) and proposes a new exclusion zone (EZ) with NPP indoor environment. The indoor EZs were affected by the multiple reflections, standing wave, and diffraction depending on the indoor geometry. To accurately analyze the variations between the indoor EZ and free-space EZ, multiple reflection ray tracing, modal analysis of a cylindrical coordinate, and measurements are performed. The results demonstrate that the proposed indoor EZ applied to the NPP environment is more practical and suitable than the EZ in free-space.
Quality of protection for mobile multimedia applications (2003)

In traditional computer systems, security is typically provided in a one-or-nothing manner; the system is either secure or insecure. Such an approach is insufficient for pervasive environments that contain heterogenous devices with varying computing resources. The small, portable handheld devices are often left unsecured due to their limited computing power. The approach is also inadequate for multimedia applications that require security as a controllable service attribute to maintain performance quality of service to levels that are acceptable to the users. Hence, we need a tunable and differentiable security framework. In this paper, we present a quality of protection (QoP) framework that resolves the inadequacies of the one-or-nothing approach by providing differential security levels for different device, user and application security requirements and preferences. We show that our QoP framework is necessary for multimedia applications to achieve the best possible security and performance levels in pervasive environments.
Wireless Access in Vehicular Environments Using BitTorrent and Bargaining (2008)

Wireless Access in Vehicular Environment (WAVE) technology such as IEEE 802.11pWireless Access in Vehicular Environment (WAVE) technology such as IEEE 802.11p has emerged as a state-of-the- art solution to vehicular communications. The major challenges in WAVE arise due to the fast changing communication environment and short durations of communications due to the mobility. As a result, it is difficult to transmit a large amount of data in such a network for vehicle-to-roadside and/or vehicle-to-vehicle communications. To overcome this problem, we propose a solution based on the idea of BitTorrent used for peer-to-peer networking, and the concept of bargaining game used in game theory. Similar to the distribution of data to peers in BitTorrent, the roadside units (RSUs) randomly distribute the data to the passing vehicles. Then, the on board units (OBUs) on the vehicles with different data, exchange the information among each other using bargaining considering channel adaptations and fairness in their achieved utility. We formulate two optimization problems - one for the RSUs and the other for the OBUs. For OBUs, the bargaining solutions are proposed which are based on three fairness criteria. For RSUs, depending on the traffic pattern, distribution of packets to the OBUs is optimized considering the different priority of the packets so that the overall utilities of the OBUs are maximized. Simulation results show that the proposed schemes can ensure fairness among the OBUs, and adapt to different traffic scenarios with different vehicular traffic intensity. has emerged as a state-of-the- art solution to vehicular communications.

Insight into the Effects of Chiral Diphosphine Ligands on the Structure and Optical Properties of the Au<sub>24</sub>Cd<sub>2</sub> Nanocluster (2022)

Introduction of chiral ligands has been regarded as an effective strategy to obtain nanoclusters with optical purity. However, how the chiral ligands work is still unclear due to the lack of structural comparison between racemic nanoclusters and the corresponding optically active ones. In this work, three structurally related Au<sub>24</sub>Cd<sub>2</sub> nanoclusters, including one racemic and two homochiral nanoclusters, were synthesized, and their crystal structures were characterized using single-crystal X-ray crystallography (SC-XRD). Based on their crystal structures, the origin of the chirality in Au<sub>24</sub>Cd<sub>2</sub> was found to be the twist of the kernel and the chiral arrangement of the metal-ligand surface. Au<sub>24</sub>Cd<sub>2</sub> protected with chiral ligands exhibits a more twisted kernel than the racemic one. Therefore, the chirality of chiral diphosphine was found to transfer from the ligands to the metal-ligand interface and then to the metal core, inducing its distortion to produce enhanced chirality. In addition, the optical properties including optical absorption and circular dichroism of these structurally related Au<sub>24</sub>Cd<sub>2</sub> nanoclusters were compared.
Towards Noise Robust Speech Emotion Recognition Using Dynamic Layer Customization (2021)

Robustness to environmental noise is important to creating automatic speech emotion recognition systems that are deployable in the real world. In this work, we experiment with two paradigms, one where we can anticipate noise sources that will be seen at test time and one where we cannot. In our first experiment, we assume that we have advance knowledge of the noise conditions that will be seen at test time. We show that we can use this knowledge to create "expert" feature encoders for each noise condition. If the noise condition is unchanging, data can be routed to a single encoder to improve robustness. However, if the noise source is variant, this paradigm is too restrictive. In-stead, we introduce a new approach, dynamic layer customization (DLC), that allows the data to be dynamically routed to noise-matched encoders and then recombined. Critically, this process maintains temporal order, enabling extensions for multimodal models that generally benefit from long-term context. In our second experiment, we investigate whether partial knowledge of noise seen at test time can still be used to train systems that generalize well to unseen noise conditions using state-of-the-art domain adaptation algorithms. We find that DLC enables performance increases in both cases, highlighting the utility of mixture-of-expert approaches, domain adaptation methods and DLC to noise robust automatic speech emotion recognition.
Preoperative Chlorhexidine Gluconate Use Can Increase Risk for Surgical Site Infections after Ventral Hernia Repair (2016)

Prehospital chlorhexidine gluconate scrub appears to increase the risk of 30-day wound morbidity in patients undergoing ventral hernia repair. These findings suggest that the generalized use of prehospital chlorhexidine might not be desirable for all surgical populations.
3D Modeling by Integrating Point Cloud and 2D Images through 3D Edge-Matching and Its Application to Architecture Modeling (2013)

The authors have developed a technology to produce a 3D surface model by detecting the 3D edges on the stereo-images of a digital camera. Then we arrived to register the 3D data obtained from the stereo-images and the 3D edge data detected on the 3D point-cloud of a Terrestrial Laser Scanner (TLS), and thus succeeded to develop the new technology to fuse the 3D data of the Camera and TLS. The basic idea is to take stereo-pictures by a digital camera around the areas where the scanner cannot, because of the occlusion. The camera, with the digital photogrammetry, can acquire the data of complicates and hidden areas instantly, thus shutting out the possibility of noises in a blink. The data of the camera are then integrated into the data of scanner to produce automatically the model of great perfection. In this paper, the authors show (1) how to detect the 3D edges on the photo images and to detect from the scanner's point cloud, (2) how to register the data of both 3D edges to produce the unified model, (3) how to assess the accuracy and the speed of analyzing process, which turned out to be quite satisfactory.

Efficacy of small-incision intraocular lens exchange of opacified Hydroview implants (2010)

Opacification of Hydroview intraocular lens (IOL) has been reported to result in visual impairment and become one of the reasons for IOL exchange.1–4 Although IOL exchange has been reported to be of visual benefit, the surgery is technically challenging because of its intraoperative complications, including rupture of the posterior capsule, zonulysis, iris prolapse and vitreous loss.1 2 5 The trisection technique was reported to be useful, which allows explantation of IOLs through a small incision and reduces the risk of complications.6 The purpose of this study is to evaluate the efficacy of small-incision trisection technique in Hydroview IOL exchange.

The retrospective clinical interventional case series study included consecutive 32 eyes of 25 patients with opacified Hydroview IOL, who underwent IOL exchange. The mean age was 76.7±9.8 years old, with a range of 57–90 years. In …
Enhanced protein isoform characterization through long-read proteogenomics (2021)

The detection of physiologically relevant protein isoforms encoded by the human genome is critical to biomedicine. Mass spectrometry (MS)-based proteomics is the preeminent method for protein detection, but isoform-resolved proteomic analysis relies on accurate reference databases that match the sample; neither a subset nor a superset database is ideal. Long-read RNA sequencing (e.g. PacBio, Oxford Nanopore) provides full-length transcript sequencing, which can be used to predict full-length proteins. Here, we describe a long-read proteogenomics approach for integrating matched long-read RNA-seq and MS-based proteomics data to enhance isoform characterization. We introduce a classification scheme for protein isoforms, discover novel protein isoforms, and present the first protein inference algorithm for the direct incorporation of long-read transcriptome data in protein inference to enable detection of protein isoforms that are intractable to MS detection. We have released an open-source Nextflow pipeline that integrates long-read sequencing in a proteomic workflow for isoform-resolved analysis.
Free-running isotropic whole-heart T2 mapping with ECG-free Pilot Tone navigation (2023)

The most commonly employed T 2 mapping techniques are 2D and make use of ECG-triggering. This may be a limitation in patients with variable heart rate and complex three-dimensional conditions. To address these limitations, we here propose an isotropic free-running 3D T 2 mapping technique that avoids ECG triggering by using Pilot Tone navigation. In three healthy volunteers, our technique produced accurate isotropic T 2 maps when compared to 2D T 2 prepared bSSFP (T 2 =41.1&amp;plusmn;4.8ms vs. 44.9&amp;plusmn;3.3ms, respectively, p=0.1), and cardiac motion was successfully resolved.
DIFFERENCES IN ESTIMATES OF CISPLATIN-INDUCED CELL KILL IN VITRO BETWEEN COLORIMETRIC AND CELL COUNT/COLONY ASSAYS (2006)

The aim of this study was to evaluate some bioassays that are different in principle: cell counting, colony forming assay, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT), sulforhodamine B (SRB), crystal violet, and alamarBlue, with respect to their ability to measure cisplatin-induced cell death of in vitro-cultivated squamous cell carcinoma of the head and neck (SCCHN). Cisplatin was applied in concentrations of 1.0, 5.0, 10.0, 50.0, and 100 microM. The cells were incubated for 1 h, and the cell survival was measured 5 d after treatment. We found the colorimetric assays and cell counting to be comparable. The colony forming assay indicated a higher degree of cell kill compared with the other techniques. Measurement of cell survival after treatment with cisplatin can be done by use of any of the above tested assays. However, the majority of SCCHN cell lines available do not form colonies easily, or at all. Therefore, comparing the chemosensitivity between such cell lines is limited to alternative assays. In this respect, any of the tested colorimetric assays can be used. However, they seem to underestimate cell kill. Cell counting is also an alternative. This technique, however, is time consuming and operator dependent, as in the case of manual counting, or relatively expensive when counting is performed electronically, compared with the colorimetric assays.
