Photoinduced electron transfer in a β,β′-pyrrolic fused ferrocene–(zinc porphyrin)–fullerene (2007)

A donor-acceptor linked triad with a short spacer (Fc-ZnP-C60) 1 was designed and synthesised to attain the longest charge-separation lifetime, 630 micros, ever reported for triads at room temperature. The ferrocene electron donor and fullerene electron acceptor of triad 1 are attached to imidazole rings fused to opposite beta,beta'-pyrrolic positions of the zinc porphyrin. After excitation of the porphyrin, electron transfer to C60 occurs within 230 ps, followed by hole transfer to ferrocene after 500 ps to produce the long-lived charge-separated state.
Performance evaluation of the time delay digital tanlock loop architectures (2015)

This article presents the architectures, theoretical analyses and testing results of modified time delay digital tanlock loop (TDTLs) system. The modifications to the original TDTL architecture were introduced to overcome some of the limitations of the original TDTL and to enhance the overall performance of the particular systems. The limitations addressed in this article include the non-linearity of the phase detector, the restricted width of the locking range and the overall system acquisition speed. Each of the modified architectures was tested by subjecting the system to sudden positive and negative frequency steps and comparing its response with that of the original TDTL. In addition, the performance of all the architectures was evaluated under noise-free as well as noisy environments. The extensive simulation results using MATLAB/SIMULINK demonstrate that the new architectures overcome the limitations they addressed and the overall results confirmed significant improvements in performance compared to the conventional TDTL system.
Drug-Coated Balloons for Restenosis Prophylaxis (2013)

Drug-coated balloons for restenosis prophylaxis provide a high local drug concentration with minimal or no systemic adverse effects. Their development was both delayed and facilitated by the introduction of drug-eluting stents: delayed because sustained release kinetics from stent platforms seemed to be essential and facilitated because prior experience with stents allowed selection of testing methods and drugs. Currently, a variety of drug-coated balloons are available, basically consisting of a coating containing paclitaxel at a dose of about 3 µg/mm² balloon surface, and different additives influencing the adherence and release of the drug, e. g., contrast agent, urea, or various amphiphilic compounds. The drug is almost completely released during a single inflation of 30 - 60 seconds. Studies in animals and several independent randomized clinical trials in coronary and peripheral arteries demonstrate effective reduction of neointimal proliferation, restenosis, and revascularization persisting for at least 2 years or 5 years according to one study in coronary arteries. Drug-coated balloons are preferably used for treating coronary in-stent restenosis and de novo and restenotic lesions in peripheral vessels. No coating-related adverse events have been observed in clinical trials. Persistent efficacy may be explained by the long residence time of paclitaxel in tissue or inhibition of an essential first step in the chain of events leading to neointimal proliferation.
The RHRPMICL1A Integrated Current Limiter: Radiation Tests and High Voltage Application (2019)

This paper provides a detailed overview of the reliability and radiation tests (both TID and SEE) performed inside the QML-V qualification phase and a high voltage application of RHRPMICL1A IC (integrated circuit) device, a rad-hard integrated current limiter designed and developed by STMicroelectronics. The device was born from the idea of ESA to have an ICL (Integrated Current Limiter) of universal use and containing most of the components for the relevant current limiter functions (such as the Latching and Re-triggerable modes), in order to avoid recurrent re-design and implementation by using discrete components. The device has obtained recently the QML-V qualification with SMD number 5962-17211. The high voltage application, described in the second part of this paper, allows using the device in power bus of 100V or higher, as those ones required more and more in the telecom satellites. The related application tests, performed in the laboratory for the validation of the proposed solution, are also presented.

Complementary Metal–Oxide–Silicon Field-Effect-Transistors Featuring Atomically Flat Gate Insulator Film/Silicon Interface (2009)

In this paper, we demonstrate newly developed process technology to fabricate complementary metal–oxide–silicon field-effect transistors (CMOSFETs) having atomically flat gate insulator film/silicon interface on (100) orientated silicon surface. They include 1,200 °C ultraclean argon ambient annealing technology for surface atomically flattening and radical oxidation technology for device isolation, flatness recovery after ion implantation, and gate insulator formation. The fabricated CMOSFET with atomically flat interface exhibit very high current drivability such as 923 and 538 µA/µm for n-channel MOSFET (nMOS) and p-channel MOSFET (pMOS) at gate length of 100 nm when combined with very low resistance source and drain contacts, four orders of magnitude lower 1/ f noise characteristics when combined with damage free plasma processes, and one decade longer time dependent dielectric breakdown (TDDB) lifetime in comparison to devices with a conventional flatness. The developed technology effectively improves the performance of the silicon-based CMOS large-scale integrated circuits (LSI).
Contemporary Management of Type B Aortic Dissection in the Endovascular Era. (2016)

Aortic dissection (AD) is one of the most common catastrophic pathologies affecting the aorta. Anatomic classification is based on the origin of entry tear and its extension. Type A dissections originate in the ascending aorta, whereas the entry tear in Type B dissections starts distal to the left subclavian artery. The patients with aortic dissection who manifest complications such as rupture, malperfusion, aneurysmal degeneration, and intractable pain are classified as complicated AD. Risk factors for developing aortic dissection include age, male gender, and aortic wall structural abnormalities. The most common presenting symptom of acute aortic dissection is pain. Malperfusion occurs as a result of end-organ ischemia due to involvement of aortic branches from the dissecting process. This can happen in various locations causing mesenteric ischemia (mesenteric vessels), stroke (aortic arch vessels), renal failure (renal arteries), spinal ischemia, and limb ischemia (iliac or subclavian arteries). Aneurysmal degeneration is the most common complication of patients with chronic Type B dissection who are managed with medical therapy. Management of Type B aortic dissection (TBAD) remains controversial. Many groups recommend conservative therapy for newly diagnosed TBAD and reserve surgical management for patients who develop complications such as rupture, malperfusion, aneurysmal dilatation, and refractory pain. The mainstay of medical therapy includes antihypertensive medication to reduced ΔP/ ΔT by lowering blood pressure and heart rate. With the continued success of thoracic endovascular aortic repair (TEVAR), this procedure has been extended to treat TBAD in selected patients. The outcomes of TEVAR are promising, with early mortality rates from 10% to 20%. With promising results from these series, some groups recommend early TEVAR in uncomplicated TBAD to prevent future adverse events. The goals of endovascular treatment of TBAD are to cover the entry tear, treat or prevent impending rupture, reestablish organ perfusion, restore flow in the true lumen, and induce the false lumen thrombosis. Patients with TBAD need long-term follow-up.
Highly-efficient conversion of glycerol to solketal over heterogeneous Lewis acid catalysts (2012)

The acetalization of acetone with glycerol to yield 2,2-dimethyl-1,3-dioxolane-4-methanol (solketal) was successfully catalyzed by mesoporous substituted silicates including the novel Hf-TUD-1 material. This reaction offers an attractive path for the conversion of glycerol, which is the main side-product in the synthesis of biodiesel, to a valuable compound with potential for industrial applications. The most promising among the heterogeneous catalysts employed in this work, Zr- and Hf-TUD-1 and Sn-MCM-41, display mainly Lewis acid properties as demonstrated by characterization with FT-IR analysis of pyridine adsorption, and achieve superior results compared to a reference solid acid catalyst such as Ultrastable zeolite Y. Especially the newly synthesized Hf-TUD-1, showing the highest conversion and turnover among the screened materials, is a promising catalyst for the acetalization of acetone with glycerol in a sustainable process. The excellent performance of these mesoporous catalysts is ascribed to their combination of acidity, wide pores, large specific surface area and relatively hydrophobic surface.
Solid state recycling of aluminum machined chip wastes by compressive torsion processing (2009)

The compressive torsion process (CTP) is applied for consolidation of aluminum machined chip wastes to investigate a possibility of a new solid state recycling for aluminum alloy. The machined chips were consolidated by the CTP under the different temperatures and rotation times, and then the microstructure and tensile properties were investigated. It was possible to consolidate aluminum chips sufficiently into a cylindrical specimen by the CTP even at room temperature. The tensile strength of the specimen processed by the CTP was higher than that of annealed alloy made from an ingot metallurgy process. The tensile strength increased as the processing temperature decreased. The enough elongation over 15% was also obtained all over the specimen processed at room and elevated temperatures. It was concluded that the CTP had the availability of a new solid state recycling process with upgrading of aluminum alloy.
Screening for Antifungal Activity of Panamanian Plants (1993)

Crude extracts of Panamian plants (153 representing 28 species from 21 families) have been screened for antifungal activity against Candida albicans and Cladosporium cucumerinum. Activity was assessed in a semiquantitative fashion by bioautography on TLC plates. When tested at 100 μg, 15% of the extracts showed activity against one of the fungi, and 9% of the extracts were active against both test organisms. The most promising extracts originate from plants used in traditional medicine, such as Bursera simaruba (Burseraceae), Gliricidia sepium (Leguminosae) and Piper auritum (Piperaceae).
High power passively mode-locked fiber laser based on graphene nanocoated optical taper (2017)

We experimentally demonstrate a passively mode-locked Er:Yb doped double-clad fiber laser using a graphene nanocoated optical taper. Averaging 20 μm of clad diameter with a length of 6 mm, such a saturable absorber enables a strong light–graphene interaction owing to the evanescent field of the excited cladding mode. With the highest pump power of 5 W, the 326th harmonic mode locking of soliton bunches with an average output power of 520 mW was obtained in a fiber ring cavity that has a fundamental frequency of 1.67 MHz. This is the highest average output power yet reported in graphene-based passively mode-locked fiber lasers.
On the NP-completeness of the Constrained Minimal Structural Controllability/Observability Problem (2014)

This paper studies the problem of, given the structure of a linear-time invariant system and a set of possible inputs, finding the smallest subset of input vectors that ensures system's structural controllability. We refer to this problem as the minimum constrained input selection (minCIS) problem, since the selection has to be performed on an initial given set of possible inputs. We prove that the minCIS problem is NP-hard, which addresses a recent open question of whether there exist polynomial algorithms (in the size of the system plant matrices) that solve the minCIS problem. To this end, we show that the associated decision problem, to be referred to as the CIS, of determining whether a subset (of a given collection of inputs) with a prescribed cardinality exists that ensures structural controllability, is NP-complete. Further, we explore in detail practically important subclasses of the minCIS obtained by introducing more specific assumptions either on the system dynamics or the input set instances for which systematic solution methods are provided by constructing explicit reductions to well known computational problems. The analytical findings are illustrated through examples in multi-agent leader-follower type control problems.
HeuristicDB (2021)

Hybrid storage systems are widely used in big data fields to balance system performance and cost. However, due to a poor understanding of the characteristics of database block requests, past studies in this area cannot fully utilize the performance gain from emerging storage devices. This study presents a hybrid storage database system, called HeuristicDB, which uses an emerging non-volatile memory (NVM) block device as an extension of the database buffer pool. To consider the unique performance behaviors of NVM block devices and the block-level characteristics of database requests, a set of heuristic rules that associate database (block) requests with the appropriate quality of service for the purpose of caching priority are proposed. Using online analytical processing (OLAP) and online transactional processing (OLTP) benchmarks, both trace-based examination and system implementation on MySQL are carried out to evaluate the effectiveness of the proposed design. The experimental results indicate that HeuristicDB provides up to 75% higher performance and migrates 18X fewer data between storage and the NVM block device than existing systems.

A 500-dpi cellular-logic processing array performs all fingerprint identification steps on one chip, from image acquisition, enhancement, to verification. Morphological functions for executing these steps are implemented in a 30/spl times/50-/spl mu/m/sup 2/ processing unit. A single-cycle datapath and a shared logic structure enable compact implementation of the processing unit. A fabricated 224/spl times/256-pixel fingerprint identification LSI demonstrates fully-functional image processing and practical accuracy of identification.
Key Frame Extraction in 3D Video by Rate-Distortion Optimization (2006)

3D video, which consists of a sequence of 3D mesh models, can provide detailed 3D information both in spatial and temporal domain. In this paper, a key frame extraction method has been developed to summarize 3D video by rate-distortion optimization. For this purpose, we introduce an effective feature vector extraction algorithm from 3D video. Prior to key frame extraction, shot detection is performed using the feature vectors as a pre-processing. Then, a rate-distortion (R-D) curve is generated in each shot, where the locations of key frames are optimized. Lastly, R-D trade-off can be achieved by optimizing a cost function with a Lagrange multiplier. Our experimental results show the extracted key frames are compact and faithful to original 3D video

The exceptionally high electronic and thermal conductivity, optical transparency, and high specific surface area, combined with excellent mechanical flexibility and environmental stability leave graphene poised to be a material of the future. This perspective introduces the importance of graphene electrodes, discusses the synthesis of graphene and transfer onto desired substrates and the role of graphene in electrodes for a broad range of flexible devices such as photovoltaic, electronic, and electrochemical energy storage.
EUS May Have Limited Impact on the Endoscopic Management of Gastric Carcinoids (2002)

Background. Carcinoids are occasionally found during gastroscopy. Endoscopic ultrasonography (EUS) can determine the depth of invasion and vascularity of submucosal tumors, including carcinoid tumors. Thus, EUS can lead to an informed decision as to whether to attempt endoscopic or surgical excision of a carcinoid. The three cases described here were found by EUS to be amenable to endoscopic resection of submucosal carcinoid tumors. In each case, the margin of the specimen obtained led to uncertainty regarding the completeness of gastroscopic excision of the tumor. Guidelines for follow-up of gastric carcinoid are few. The incompleteness of endoscopic resection of submucosal tumors, with tumor found at the specimen margin, indicates that careful follow-up and/or consideration of other means of excision are indicated.
Functional properties of endosperm protein from size‐fractionated broken rice kernels generated after milling of parboiled and nonparboiled rice (2019)

Abstract Background and objectives The quantity and functionality of proteins in different sizes of broken rice (brokens) may inform the different pasting properties observed in rice flour derived from brokens. This study was conducted to determine properties of protein from size‐fractionated parboiled and nonparboiled milled broken rice kernels. In addition, the research sought to determine the extent to which properties of proteins influence functionality of rice flour derived from the studied brokens. Findings Whole kernels and medium brokens of nonparboiled rice recorded the highest quantity and yield of protein isolate, while the lowest was recorded in large brokens. A strong negative correlation existed between sample protein content and the size of parboiled brokens. Parboiled samples had decreased protein extractability than nonparboiled samples. Emulsifying activity (EA) of parboiled rice had a significantly strong negative linear association with size of brokens. Emulsifying stability (ES) on the other hand had a significantly strong positive linear association with size of brokens, and about 82% of the variation in ES was explained by size. The trend was opposite in the nonparboiled stream with ES having a strong negative linear association with size. A very strong positive linear association existed between foaming capacity (FC), foaming stability (FS), and size of nonparboiled samples. Surface hydrophobicity (SH) was significantly different among parboiled and nonparboiled rice, with weak positive correlations existing between SH and size of parboiled and nonparboiled samples. Solubility curves in nonparboiled stream were more uniform than the parboiled stream. Strong significant positive correlations existed between peak, trough, breakdown, final, setback viscosities, and ES. A strong positive linear association was observed between peak, trough, final viscosities, and FS. Differences in protein contents of whole kernels and size‐fractionated brokens may be attributed to either the variations in the distribution of inherent components of the kernel or variations in milling efficiency. Results in this research are specific for long‐grain hybrid rice and may vary depending on cultivar and environmental factors. Conclusions Proteins influence the pasting properties of brokens. Understanding the functional properties of size‐fractionated broken rice kernels from parboiled and nonparboiled streams is essential in directing the right kind of brokens to the right end‐use. Significance and novelty This study provides useful information to better utilization and value addition of brokens.

<title>Tissue modification with feedback: the smart scalpel</title> (1998)

While feedback control is widespread throughout many engineering fields, there are almost no examples of surgical instruments that utilize a real-time detection and intervention strategy. This concept of closed loop feedback can be applied to the development of autonomous or semi- autonomous minimally invasive robotic surgical systems for efficient excision or modification of diseased tissue. Spatially localized regions of the tissue are first probed to distinguish pathological from healthy tissue based on differences in histochemical and morphological properties. Energy is directed to only the diseased tissue, minimizing collateral damage by leaving the adjacent healthy tissue intact. Continuous monitoring determines treatment effectiveness and, if needed, enables real-time treatment modifications to produce optimal therapeutic outcomes. The present embodiment of this general concept is a microsurgical instrument we call the Smart Scalpel, designed to treat skin angiodysplasias such as port wine stains. Other potential Smart Scalpel applications include psoriasis treatment and early skin cancer detection and intervention.

Influence of Statistical Fluctuation on Reproducibility and Accuracy of SUVmax and SUVpeak: A Phantom Study (2015)

SUVmax was variable and overestimated as the scan time decreased and the sphere size increased. In contrast, SUVpeak was a more robust and accurate metric than SUVmax. The measurements of SUVpeak (or SUVpeak normalized to lean body mass) in addition to SUVmax are desirable for reproducible and accurate quantification in clinical situations.
