High-Capacitance-Density ${p}$ -GaN Gate Capacitors for High-Frequency Power Integration (2018)

The p-GaN gate capacitors with a metal/p-GaN/AlGaN/GaN structure are demonstrated on an enhancement-mode (E-mode) GaN-on-Si power device platform. High capacitance density of >170 nF/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> is obtained with an operating voltage range of 0 ~ 7 V. Frequency response of the p-GaN gate capacitors with circular and interdigitated layout design are characterized. It is found that the interdigitated layout can suppress the distribution effect and reduce the equivalent series resistance, and thus can significantly enhance the capacitor's high-frequency performance. The fabrication process of the p-GaN gate capacitors is fully compatible with the E-mode GaN power transistors, and thus can be seamlessly implemented as one of the on-chip peripheral components for GaN-based power integrated circuits.
Three Electron Reversible Redox Reaction in Sodium Vanadium Chromium Phosphate as a High‐Energy‐Density Cathode for Sodium‐Ion Batteries (2020)

Abstract A sodium‐ion battery operating at room temperature is of great interest for large‐scale stationary energy storage because of its intrinsic cost advantage. However, the development of a high capacity cathode with high energy density remains a great challenge. In this work, sodium super ionic conductor‐structured Na 3 V 2− x Cr x (PO 4 ) 3 is achieved through the sol–gel method; Na 3 V 1.5 Cr 0.5 (PO 4 ) 3 is demonstrated to have a capacity of 150 mAh g −1 with reversible three‐electron redox reactions after insertion of a Na + , consistent with the redox couples of V 2+ / 3+ , V 3+ / 4+ , and V 4+ / 5+ . Moreover, a symmetric sodium‐ion full cell utilizing Na 3 V 1.5 Cr 0.5 (PO 4 ) 3 as both the cathode and anode exhibits an excellent rate capability and cyclability with a capacity of 70 mAh g −1 at 1 A g −1 . Ex situ X‐ray diffraction analysis and in situ impedance measurements are performed to reveal the sodium storage mechanism and the structural evolution during cycling.
Feasibility and proof of concept of a proprietary non-contact ablation system with low intensity collimated ultrasound (2023)

Abstract Funding Acknowledgements Type of funding sources: Private company. Main funding source(s): Heailum Medical Inc. Background Utilization of collimated acoustic energy transition as an ablation energy source has the advantage of propagation through blood with negligible absorption. This allows delivery of non-contact, directional and precise ablation lesions to cardiac tissue. In addition, with dual mode ultrasound technology real-time monitoring of the tissue is possible during ablation. Aim To evaluate a proprietary ultrasound-based ablation system in swine and define the characteristics of the isolated ablation lesions and lines performed in-vivo. Methods In female large white swines, bilateral thigh muscle prep ablations were performed using different time and energy ablation parameters while tip to tissue distance measured with the imaging B-mode and set to 10mm. Lesions were analysed for maximal depth and width. Additional assessment for contiguous linear ablation was performed in the thigh muscle, SVC and within the coronary sinus with the transducer rotated to the endocardial direction. Tissue was fixed in formalin and gross pathological examination with lesion measurement was performed. Results 36 distinct ablation lesions were performed in the thigh prep model. No steam pops were observed for any of the lesions. Mean necrotic lesion depth was 5.35 ± 1.5mm, with increased time with greater influence on dimensions compared to small changes in energy delivered (Figure 1). Reversible damage influenced additional 29% of tissue depth, while 55% additional tissue width was reversible. Linear ablation performed at 2.5mm inter-lesion distance showed contiguous lines, with transmural effect in both SVC and coronary sinus. Conclusions A novel ultrasound based catheter ablation has the ability for non-contact effective ablation in cardiac tissue with directional and tailored energy selection to achieve transmural atrial ablation. Additional in-vivo experimentation will allow refinement of this tool for both isolated lesions and linear ablation while enabling tissue visualization.
Behavioural Approach to Network Anomaly Detection for Resource-Constrained System – Presentation of the Novel Solution – Preliminary Study (2019)

In this paper some preliminary results of network anomaly detection for resource-constrained systems have been presented. All described algorithms are embedded into a three-tier system application. The presented solution is a response to nowadays trends in computer/network security domain that indicate gradual shifting from signature-based anomaly detection typically based on some selected statistical measures toward systems that are based on behavioural analysis of computer systems and/or networks. The presented system requirements, explain relevant terminology as well as we include some selected results and their analysis. The solution is potentially destined for very resource-constrained systems (IoT specifically), all tests were carried out in an example network to additionally analyse their effect of the presented approach on the computer resources.
Information Technologies for Set-designers (1999)

The project The set-designer and the instruments of his days–New information technologies for the theatre was proposed in the second edition of the Solomon R. Guggenheim Foundation competition, Impresa &amp; Cultura, Intrapresae Collezione Guggenheim enterprise, being awarded a mention by the jury for the originality of the application in a typical Italian field, the opera theatre, in need of deep innovations.

On the occasion of the introduced project was trained in the Alias software secrets and he could work closely with the professionals of the Stage setting departments of the theatres involved in the experimental project. At the same time he could finished his studies with a thesis on the use of computer technologies in the theatre.
Accelerating virtual high‐throughput ligand docking: current technology and case study on a petascale supercomputer (2013)

In this paper we give the current state of high-throughput virtual screening. We describe a case study of using a task-parallel MPI (Message Passing Interface) version of Autodock4 [1], [2] to run a virtual high-throughput screen of one-million compounds on the Jaguar Cray XK6 Supercomputer at Oak Ridge National Laboratory. We include a description of scripts developed to increase the efficiency of the predocking file preparation and postdocking analysis. A detailed tutorial, scripts, and source code for this MPI version of Autodock4 are available online at http://www.bio.utk.edu/baudrylab/autodockmpi.htm.
Zeolitic Imidazolate Framework (ZIF)‐Derived, Hollow‐Core, Nitrogen‐Doped Carbon Nanostructures for Oxygen‐Reduction Reactions in PEFCs (2013)

The facile synthesis of a porous carbon material that is doped with iron-coordinated nitrogen active sites (FeNC-70) is demonstrated by following an inexpensive synthetic pathway with a zeolitic imidazolate framework (ZIF-70) as a template. To emphasize the possibility of tuning the porosity and surface area of the resulting carbon materials based on the structure of the parent ZIF, two other ZIFs, that is, ZIF-68 and ZIF-69, are also synthesized. The resulting active carbon material that is derived from ZIF-70, that is, FeNC-70, exhibits the highest BET surface area of 262 m(2) g(-1) compared to the active carbon materials that are derived from ZIF-68 and ZIF-69. The HR-TEM images of FeNC-70 show that the carbon particles have a bimodal structure that is composed of a spherical macroscopic pore (about 200 nm) and a mesoporous shell. X-ray photoelectron spectroscopy (XPS) reveals the presence of Fe-N-C moieties, which are the primary active sites for the oxygen-reduction reaction (ORR). Quantitative estimation by using EDAX analysis reveals a nitrogen content of 14.5 wt.%, along with trace amounts of iron (0.1 wt.%), in the active FeNC-70 catalyst. This active porous carbon material, which is enriched with Fe-N-C moieties, reduces the oxygen molecule with an onset potential at 0.80 V versus NHE through a pathway that involves 3.3-3.8 e(-) under acidic conditions, which is much closer to the favored 4 e(-) pathway for the ORR. The onset potential of FeNC-70 is significantly higher than those of its counterparts (FeNC-68 and FeNC-69) and of other reported systems. The FeNC-based systems also exhibit much-higher tolerance towards MeOH oxidation and electrochemical stability during an accelerated durability test (ADT). Electrochemical analysis and structural characterizations predict that the active sites for the ORR are most likely to be the in situ generated N-FeN(2+2)/C moieties, which are distributed along the carbon framework.
Aging and Visual Counting (2010)

Here we show that age reduces the ability to correctly enumerate in a glance, but the accuracy (veridicality), on average, remains unchanged with advancing age. Control experiments indicate that the degraded performance cannot be explained by optical, retinal or other perceptual factors, but is cortical in origin.
Efficient synthesis of aluminosilicate RTH zeolite with good catalytic performances in NH3-SCR and MTO reactions (2018)

The synthesis of aluminosilicate RTH zeolite is very fast in the presence of 2,6-methyl-<italic>N</italic>-methylpyridinium cations.
Extracellular Vesicles Secreted by Bone Marrow- and Adipose Tissue-Derived Mesenchymal Stromal Cells Fail to Suppress Lymphocyte Proliferation (2015)

Recently, mesenchymal stromal cell-derived extracellular vesicles (MSC-EVs) have been suggested as an alternative to MSCs for the treatment of various inflammatory disorders. However, while a first case report observed beneficial therapeutic effects of repeated MSC-EV infusions in a patient with therapy-refractory graft-versus-host disease, in vitro findings revealed that MSC-EVs were significantly less immunosuppressive than their parental cells. In this study, we compared the immunosuppressive potency of MSCs derived from bone marrow (BM-MSCs) and adipose tissue (AT-MSCs), with their secreted EVs in a standardized lymphocyte proliferation assay (LPA). Both BM-MSCs and AT-MSCs exhibited a remarkable inhibition of lymphocyte proliferation (LP) (88.1%±1.5% and 75.5%±1.5%, respectively), while isolated EVs derived from them failed to suppress LP at dose levels up to 100 μg/mL. Thus, our data further substantiate previous reports suggesting that cell-cell contact plays an important role on the immunosuppressive potential mediated by MSCs. Hence, MSC-EVs are still a matter of debate and might not be a reasonable substitute for MSCs with regard to the immunosuppressive function. Collectively, these contrasting findings may also reflect the importance of relevant translational aspects when designing new studies. Standardization of MSC culture conditions before EV collection as well as isolation and characterization methods with regard to EV purity are urged. Moreover, before clinical use, dose-finding studies evaluating MSC-EV preparations in suitable preclinical models are warranted.

Hollow-core fiber Characterization with Correlation-Optical Time Domain Reflectometry (2021)

Using a Correlation-OTDR, we characterized the temperature-induced group delay variations of two nested antiresonant nodeless hollow core fibers. The temperature sensitivity of both is substantially less than for SSMF with some dependency on coating type.
Effect of the ultraconserved noncoding RNA uc.338 on cellular growth of hepatocarcinoma. (2011)

202 Background: The role of non-protein coding (nc)RNAs in cancer is unknown but emerging evidence suggests that deregulated expression of ncRNA may contribute to cancer pathogenesis. We sought to examine the role of ultraconserved ncRNA (ucRNA) that are 100% conserved across the human, rat and mouse genomes in hepatocellular cancers (HCC). Methods: Whole genome ucRNA expression profiling was performed using a custom microarray, and verified by real time PCR in cell lines and by in situ hybridization in a tissue microarray comprising of 221 human HCC, 72 non cirrhotic (NC) and 97 cirrhotic (C) liver tissues. ucRNA expression was manipulated with siRNA or plasmid-over-expressing ucRNA, and the effects on anchorage-dependent and independent growth, and cell cycle assessed using cell viability, soft agar assays and flow cytometry. Gene ontology analysis was performed by evaluating uc338-dependent changes on mRNA expression using Affymetrix chips. Results: 56 ucRNAs were aberrantly expressed with 33 increased and 23 decreased in HepG2 cells compared to non-malignant hepatocytes. The greatest change was observed with uc.338 (6.9-fold increase). uc.338 expression was significantly increased in several HCC cell lines. uc.338 expression was detected in 170 cases (77%) of HCC, with 62% of these showing a moderate to strong expression. Compared to non- malignant adjacent tissue, uc.338 expression was increased in 97/156 of HCC. The mean % of cells expressing uc.338 was 4% in NC liver, 15% in C and 24% in HCC. Inhibition of uc.338 reduced anchorage dependent and independent growth, and cell cycle progression in both human and murine malignant hepatocytes. Gene annotation enrichment analysis of mRNAs that were altered by inhibition of uc.338 expression identified the top over-represented GenMAPP pathways as: cell cycle, mRNA processing, RNA transcription, G1 to S cell cycle. Moreover, enforced expression of uc.338 increased cell growth in nonmalignant hepatocytes. Conclusions: These data showing that uc.338 is selectively overexpressed in HCC and promotes cell growth provides new insights into the role of RNA genes in HCC. No significant financial relationships to disclose.
A Retrospective Comparison of DLI and gDLI for Post-Transplant Treatment (2020)

Donor lymphocyte infusion (DLI) is used to prevent or treat haematological malignancies relapse after allogeneic stem cell transplantation (allo-SCT). Recombinant human granulocyte colony-stimulated factor primed DLI (gDLI) is derived from frozen aliquots of the peripheral blood stem cell collection. We compared the efficacy and safety of gDLI and classical DLI after allo-SCT. We excluded haploidentical allo-SCT. Initial diseases were acute myeloblastic leukaemia (<i>n</i> = 45), myeloma (<i>n</i> = 38), acute lymphoblastic leukaemia (<i>n</i> = 20), non-Hodgkin lymphoma (<i>n</i> = 10), myelodysplasia (<i>n</i> = 8), Hodgkin lymphoma (<i>n</i> = 8), chronic lymphocytic leukaemia (<i>n</i> = 7), chronic myeloid leukaemia (<i>n</i> = 2) and osteomyelofibrosis (<i>n</i> = 1). Indications for DLI were relapse (<i>n</i> = 96) or pre-emptive treatment (<i>n</i> = 43). Sixty-eight patients had classical DLI and 71 had gDLI. The response rate was 38.2%, the 5-year progression-free survival (PFS) rate was 38% (29-48) and the 5-year overall survival (OS) rate was 37% (29-47). Graft versus host disease rate was 46.7% and 10.1% of patients died from toxicity. There were no differences between classical DLI and gDLI in terms of response (<i>p</i> = 0.28), 5-year PFS (<i>p</i> = 0.90), 5-year OS (<i>p</i>. 0.50), GvHD (<i>p</i> = 0.86), treated GvHD (<i>p</i> = 0.81) and cause of mortality (<i>p</i>. 0.14). In conclusion, this study points out no major effectiveness or toxicity of gDLI compared to classical DLI.
Scalable Softcore Vector Processor for Biosequence Applications (2006)

Currently available genome databases are growing exponentially in size, making it difficult for software analysis tools to keep up. A number of hardware accelerators utilizing special purpose VLSI (Blas, et al., 2005) or reconfigurable hardware (Hoang, 1993) have been proposed. However, they are inflexible; support for new applications usually requires a laborious redesign. None of these accelerators can be easily adapted to other applications that require differing hardware resources. The design philosophy of the softcore vector processor is based on two important goals: adaptability and performance. Instruction based execution allows programmable support for a large number of algorithms. The fact that different classes of applications require different subsets of hardware resources, argues for a customizable hardware design built from primitives. The second goal was to achieve programmability without sacrificing performance. The SVP was designed to perform competitively with full custom solutions available in the market

Nanometer-scale resolution of a chloromethylated calixarene negative resist in electron-beam lithography: Dependence on the number of phenolic residues (2000)

We have investigated a chloromethylated calixarene, p-chloromethylmethoxcalix[n]arene (CMC[n]AOMe) (n=5,6,7), as a negative resist in electron-beam lithography. Each CMC[n]AOMe resist has a resolution of about 12 nm and a sensitivity of about 0.8 mC/cm2 which varies slightly with n (or molecular weight). A sub-10-nm Si wire has been fabricated by halide plasma etching and a CMC[n]AOMe resist as an etching mask. Because the resist pattern edge is smooth, Si wires with 7-nm width and 10-μm length were performed without any breaking.
Sequence of Courses on Particle Transport, Deposition and Removal and Engineering of Nano/Micro-Scale Systems (2010)

Small (nano-/micro-scale) particle transport, deposition and removal are of critical importance in many industries including semiconductor manufacturing, imaging, pharmaceutical and food processing. In addition, numerous environmental processes involve particle transport, deposition and removal. In the last decade, significant research progress in the areas of nano- and micro-particle transport, deposition and removal has been made. In this project, a series of courses was developed to make these class of new important research findings available to seniors and graduate students in engineering through developing and offering of specialized curricula at Clarkson University. The project involved integration of particle transport, deposition and removal numerical simulations and experiments in the developed courses. The course materials are mostly made available on the web and some courses have been taught at Clarkson University and Syracuse University campuses simultaneously. Based on the course materials, a series of short courses was also offered at several countries. The first two courses on particle transport, deposition and removal are composed of four modules: (i) fundamental of particle transport, dispersion, deposition and removal, (ii) computational modeling of particle transport, deposition and removal, (iii) experimental study of particle transport, deposition and removal, and (iv) industrial applications of particle transport, deposition and removal. Based on this course development experience, more recently, a new undergraduate course (Nano/Micro-scale Systems Engineering) was developed. The course development and implementation was supported a grant from NSF under the Nanotechnology Undergraduate Education program following an initial grant from Clarkson University. The chief instructional objective of the new course is to familiarize the students to the design, analysis, simulation and implementation/fabrication of nano/micro-scale engineering systems. This nanotechnology course consists of three main components to address a set of its well-defined educational objectives: (i) lectures developed and delivered by a multidisciplinary team at Clarkson University, (ii) instructions on computational design/analysis and simulation tools, and (iii) a hands-on workshop for gaining experience with cleanroom procedures and fabrication facilities. The second component has been developed with help of a software company. The third component is being realized through collaboration with the NNIN supported CNF facility at Cornell University as a hands-on workshop for the Clarkson students. An outline of this ongoing course development activity has been given and main features of the course has been discussed.
