Optimal Sensor Placement for Topology Identification in Smart Power Grids (2019)

Accurate network topology information is critical for secure operation of smart power distribution systems. Line outages can change the operational topology of a distribution network. As a result, topology identification by detecting outages is an important task to avoid mismatch between the topology that the operator believes is present and the actual topology. Power distribution systems are operated as radial trees and are recently adopting the integration of sensors to monitor the network in real time. In this paper, an optimal sensor placement solution is proposed that enables outage detection through statistical tests based on sensor measurements. Using two types of sensors, node sensors and line sensors, we propose a novel formulation for the optimal sensor placement as a cost optimization problem with binary decision variables, i.e., to place or not place a sensor at each bus/line. The advantage of the proposed placement strategy for outage detection is that it incorporates various types of sensors, is independent of load forecast statistics and is cost effective. Numerical results illustrating the placement solution are presented.
Lycopene attenuates chlorpyrifos-induced hepatotoxicity in rats via activation of Nrf2/HO-1 axis (2023)

Chlorpyrifos (CPF), is an organophosphate pesticide that is widely used for agricultural purposes. However, it has well-documented hepatotoxicity. Lycopene (LCP) is a plant-derived carotenoid with antioxidant and anti-inflammatory activities. The present work was designed to evaluate the potential hepatoprotective actions of LCP against CPF-induced hepatotoxicity in rats. Animals were assigned into five groups namely: Group I (Control), Group II (LCP), Group III (CPF), Group IV (CPF + LCP 5 mg/kg), and Group V (CPF + LCP 10 mg/kg). LCP offered protection as evidenced by inhibiting the rise in serum activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) induced by CPF. This was confirmed histologically as LCP-treated animals showed liver tissues with less proliferation of bile ducts and periductal fibrosis. LCP significantly prevented the rise in hepatic content of malondialdehyde (MDA), depletion of reduced glutathione (GSH), and exhaustion of glutathione-s-transferase (GST) and superoxide dismutase (SOD). Further, LCP significantly prevented hepatocyte death as it ameliorated the increase in Bax and the decrease in Bcl-2 expression induced by CPF in liver tissues as determined immunohistochemically. The observed protective effects of LCP were further confirmed by a significant enhancement in heme oxygenase-1 (HO-1) and NF-E2-related factor 2 (Nrf2) expression. In conclusion, LCP possesses protective effects against CPF-induced hepatotoxicity. These include antioxidation and activation of the Nrf2/HO-1 axis.
Treatment with a Proton Pump Inhibitor for a Laryngeal Granuloma with GERD (2015)

Reflux laryngitis and has been known to be caused by gastro-esophageal reflux disease (GERD). In severe case of laryngitis, a granuloma might be seen at the unilateral vocal cord and the lesion is very difficult to be controlled by surgery due to its high recurrence rate. Proton pump inhibitor (PPI) therapy can reduce the secretion of gastric juice. These drugs, therefore, have been generally used to relieve the symptoms of GERD, but their usefulness for laryngeal granuloma has not been clarified so far.We have treated two cases of laryngeal granuloma with a PPI which were resistant to surgery and other medications including steroids. In both cases, remarkable improvement was seen following PPI treatment. These findings suggest that PPI could be useful in laryngeal granuloma patients with GERD before laryngomicrosurgery. In addition to its potential efficacy, PPI treatment is inexpensive and severe side effects are seldom seen.
Recombinant single-chain and disulfide-stabilized Fv-immunotoxins that cause complete regression of a human colon cancer xenograft in nude mice (1996)

Monoclonal antibody (MAb) 55.1 specifically recognizes an antigen on the surface of human colon adenocarcinoma cells. We constructed recombinant immunotoxins composed of the heavy- and light-chain variable regions of MAb 55.1 fused to a recombinant form of Pseudomonas exotoxin (PE). The heavy- and light-chain variable regions are stabilized by 2 means. One is by a flexible peptide linker to form a single-chain antigen binding protein (scFv) and the second by an interchain disulfide bond engineered between structurally conserved framework regions. These are termed disulfide stabilized Fvs (dsFv). The 2 Fv forms are fused to truncated forms of PE lacking the cell binding domain. The recombinant scFv- and dsFv-immunotoxins were expressed in E. coli and purified to near homogeneity. The scFv- and dsFv-immunotoxins were shown to be specifically cytotoxic to human colon adenocarcinoma cell lines. The scFv-immunotoxin containing PE38KDEL was more active than the immunotoxin containing PE38 with the native carboxyl terminus (REDLK). However, the PE38KDEL immunotoxin is about 2-fold more toxic in mice, and therefore it does not appreciably increase the therapeutic window in mice. Intravenous administration of the scFv- and dsFv- recombinant immunotoxins caused complete regression of a human colon carcinoma (Colo205) growing subcutaneously in immunodeficient mice. The dsFv-immunotoxin has better antitumor activity compared with its scFv-immunotoxin counterpart.
Robust synchronization technique for mobile DTV broadcasting system (2010)

Synchronization is considered an important design issue for the implementation of digital television (DTV) receiver, specially for proper reception of multipath distorted signal at low signal to noise ratio (SNR). This challenge is more pronounced in complex multipath channel scenarios and for high mobility applications in presence of carrier frequency offset (CFO). In this paper, time domain correlation technique based on multiple PN-511 sequences is proposed to improve the synchronization performance of DTV broadcasting system that is robust against multipath impairments and CFO. Due to self-resolving capability of the multipath components, proposed synchronization algorithm provides better performance than conventional single PN-511 based algorithm in complex multipath channel. Since only the received adjacent PN-511 sequences are considered in the correlation process, the proposed technique is robust against CFO as well. In addition, the proposed technique provides higher peak-to-noise ratio (PNR), therefore this technique can be effectively used at low SNR conditions. Further, maximum likelihood (ML) estimation for multiple PN-511 based algorithm is carried out to evaluate the feasibility of the proposed algorithm.
Distance-Dependent Solid Electrolyte Interphase Control by Electrochemical Pretreatment (2022)

A new method to control the morphology and chemical composition of the solid electrolyte interphase (SEI) on the Si anode via electrochemical pretreatment with variation of the distance between the counter electrode and the working electrode has been investigated. This fundamental investigation reveals that the chemical composition and structure of the SEI are dependent on the distance between the electrodes during electrochemical pretreatment. The electrochemical pretreatment in a conventional coin cell or with a narrow gap between the electrodes (0.5 mm) generates a SEI composed of a mixture of Li2CO3 and LiF on the Si anode. However, with a large distance between the electrodes (≥2 mm), a LiF-dominant surface film is generated with well-dispersed LiF nanoparticles (<500 nm), improving the electrochemical performance of the Si anode. This finding provides insight into the potential to use distance between electrodes during electrochemical pretreatment as a method to control the structure and function of the SEI.

Imaging of hyperalgesia in rats by functional MRI (2006)

Cerebral activation in response to sequences of temperature boosts at the hindpaw was observed in functional magnetic resonance imaging (fMRI) experiments in isoflurane anesthetized rats. Cingulate, retrosplenial, sensory-motor and insular cortex, medial and lateral posterior thalamic nuclei, pretectal area, hypothalamus and periaqueductal gray were the most consistently, often bilaterally activated regions. With the same experimental paradigm, activity changes in the brain following subcutaneous zymosan injection into one hindpaw were detected. These changes developed over time (up to 4h) in parallel with the temporal development of hyperalgesia shown by a modified Hargreaves test, thus reflecting processes of peripheral and central sensitization. When the heat stimuli were applied to the inflamed paw, the hyperalgesia manifested itself as a volume increase of the activated areas and/or an enhanced functional blood oxygenation level dependent (BOLD) signal in all the above-mentioned brain regions. Enhanced BOLD signals were also observed in response to stimulation of the contralateral non-injected paw. They were significant in higher associative regions and more pronounced in output-related than in input-related brain structures. This indicates additional sensitization processes in the brain, which we named cerebral sensitization. Long lasting zymosan-induced hyperalgesia could be monitored with high resolution fMRI in rats under isoflurane anaesthesia. This technique may provide an effective method for testing new analgesics and studying structure specific pain processing.

Nachsäuleninjektion als Verfahren zur schnellen und präzisen Quantifizierung von Radioprodukten mittels analytischer HPLC (2023)

Ziel/Aim Während der Radiosyntheseoptimierung wird der radiochemische Umsatz (RCU) üblicherweise durch HPLC-Analyse des mit H2O verdünnten Reaktionsgemischs bestimmt. Dabei kann es aufgrund der geringen Wiederfindungsrate von F-18-Fluorid jedoch zu einer erheblichen Überschätzung der isolierten radiochemischen Ausbeute (RCA) kommen. Hier zeigen wir, dass dieser Effekt durch Nachsäuleninjektion berücksichtigt und damit Radioprodukte zuverlässig quantifiziert werden können.
Physical Properties of 1.3 μm InAs-Based Quantum Dot Laser on Silicon (2018)

The temperature performance of InAs/Si quantum dot lasers is studied using temperature-dependent characterization of the stimulated and spontaneous emission and discussed in terms of localization effects due to the inhomogeneity of the active region and the interplay of radiative and non-radiative recombination.
Constructal law of vascular trees for facilitation of flow (2014)

Diverse tree structures such as blood vessels, branches of a tree and river basins exist in nature. The constructal law states that the evolution of flow structures in nature has a tendency to facilitate flow. This study suggests a theoretical basis for evaluation of flow facilitation within vascular structure from the perspective of evolution. A novel evolution parameter (Ev) is proposed to quantify the flow capacity of vascular structures. Ev is defined as the ratio of the flow conductance of an evolving structure (configuration with imperfection) to the flow conductance of structure with least imperfection. Attaining higher Ev enables the structure to expedite flow circulation with less energy dissipation. For both Newtonian and non-Newtonian fluids, the evolution parameter was developed as a function of geometrical shape factors in laminar and turbulent fully developed flows. It was found that the non-Newtonian or Newtonian behavior of fluid as well as flow behavior such as laminar or turbulent behavior affects the evolution parameter. Using measured vascular morphometric data of various organs and species, the evolution parameter was calculated. The evolution parameter of the tree structures in biological systems was found to be in the range of 0.95 to 1. The conclusion is that various organs in various species have high capacity to facilitate flow within their respective vascular structures.
Land Cover and Socio-economic Characteristics in the Eight Counties of Alabama: A Spatial Analysis (2004)

This study employed a clustering algorithm and a logistic regression analysis to examine the relationship between cropland and demographic attributes obtained at the census block group level. The result indicated that population density, African Americans, and poverty are significantly related with crop land use in the region.
Genetic Code Expansion in Zebrafish Embryos and Its Application to Optical Control of Cell Signaling (2017)

Site-specific incorporation of unnatural amino acids into proteins provides a powerful tool to study protein function. Here we report genetic code expansion in zebrafish embryos and its application to the optogenetic control of cell signaling. We genetically encoded four unnatural amino acids with a diverse set of functional groups, which included a photocaged lysine that was applied to the light-activation of luciferase and kinase activity. This approach enables versatile manipulation of protein function in live zebrafish embryos, a transparent and commonly used model organism to study embryonic development.
The necessity for and use of CDMA transmitter filtering in overlay systems (1998)

The concept of code division multiple access (CDMA) overlay has been proposed as a way to take advantage of the unused bandwidth available in sparsely populated narrowband systems. Most research up to this point has focused on the effects of the narrowband system on the CDMA system. However, because the CDMA system is likely to be overlaid on a narrowband system that is already established, it is of equal or greater importance to examine how the CDMA overlay would affect the narrowband system's performance. It is shown that even a lightly loaded CDMA system can have a detrimental effect on a narrowband system to the point where the possibility of overlay may be precluded. To solve this problem, the idea of notch filtering the CDMA signals in an effort to avoid those bands already occupied by narrowband users is examined. For certain filtering methods the effects of CDMA interference on the narrowband system are shown to be greatly reduced, thus making overlay feasible from the perspective of the narrowband system. For the CDMA system, the performance of the minimum mean-squared error (MMSE) receiver was evaluated and it was found to work quite well with CDMA signals that have been notched. With CDMA transmitter filtering, the prospects for overlay become very encouraging.
Relationship between visual complexity and aesthetics: Application to beauty prediction of photos (2015)

Automatic evaluation of visual content by its aesthetic merit is becoming exceedingly important as the available volume of such content is expanding rapidly. Complexity is believed to be an important indicator of aesthetic assessment and widely used. However, psychological theories concerning complexity are only verified on limited situations, and the relationship between complexity and aesthetic experience on extensive scope of application is not yet clear. To this end, we designed an experiment to test human perception on the complexity of various photos. Then we propose a set of visual complexity features and show that the complexity level calculated from the proposed features have a near-monotonic relationship with human beings’ beauty expectation on thousands of photos. Further applications on beauty predication and quality assessment demonstrate the effectiveness of proposed method.
Improving color saturation for color managed images rendered using the perceptual intent (2007)

In many cases, rendering images using color management approach may result in unsatisfactory color, particularly for cases when the gamut mismatch is large and the source / destination profile pair does not lead to a satisfactory color. This more often the case when images on laptop computer screens with limited color gamut are transferred to print and color management is used. For those cases, we present a method of improving image quality by manipulating the display profile such that the color quality of the printouts is not compromised by the small gamut of the portable display and color management. The basic idea consists of using in the color management pipeline of a virtual gamut that has the role of either the source or of the destination depending on the type of transformation and the gamut size of the source and destination in the color management pipeline. In case the mismatch between the source and destination gamut is under a threshold the virtual gamut is not used. This virtual gamut is constructed directly in the CIE 1931 chromaticity diagram, although other color spaces may be used. A procedure to derive a constant hue line from two adjacent lines is presented. The chromaticities of the virtual gamut are computed based on the replaced gamut chromaticities and a weighting factor computed automatically at the time of rendering. The method proves to give very pleasing results in prints for example and the boost in saturation approximates very well the color enhancement achieved in silver halide photographic prints even for relatively modest print media.
Design and fabrication of LMA low-bending loss leakage channel fibers (2012)

We report design and fabrication of both all-glass fluorine doped and air-clad leakage-channel fibers (LCF) to achieve large-mode-area (LMA) and effectively single-mode operation with a minimum bending loss (BL) for compact Yb-doped fiber laser delivery applications. The BL and effective area for the fabricated LCF were numerically calculated by using full-vector FEM for both A-A' plane and B-B' plane. A high enough differential BL between the fundamental mode (~ 0.1dB/m) and the higher order mode (100dB/m) can be found in A-A' plane. The measured BL of the air-clad LCF was 0.09 dB/m and effective area of 350 μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> for 5 cm bending radius which is the best performance for minimum bendable LCF. The dispersion characteristic of the air-clad LCF is calculated and it has zero dispersion at 1.264μm. Single-mode nature of 1064nm light was measured at bent LCF. All-glass F-doped LCF was fabricated for easy splicing with standard SMF.
Analysis of High-Reliable and Low-Latency Communication Enablers for New Radio Unlicensed (2020)

In this paper, the performance impact of several high-reliable and low-latency communications technology enablers in the unlicensed spectrum for standalone operation is evaluated. Firstly, a comparison between MulteFire (MF) and New Radio-Unlicensed (NR-U) is established. It is shown that higher sub-carrier spacings and shorter processing times provide clear latency reduction benefits. Additionally, different transmission time intervals (TTI) durations are evaluated. Shortening the TTI duration decreases the latency by a factor of 5.75 at 99.99% reliability and reduces the uplink Listen Before Talk (LBT) blocking probability by 18%. The possibility of having multiple switching points during the frame is also evaluated. It is concluded that having multiple switching points provides a latency reduction mainly due to the reduction of the number of channel accesses and the reduced gaps within the frame. A time-diversity technique to cope with high uplink LBT blocking probability is also evaluated. By combining the aforementioned features, a latency reduction factor of 31 is achieved when optimized NR-U and MulteFire performances are compared.
Thermal Policies and Active Workload Migration Within Data Centers (2009)

Energy consumption and energy prices are two critical concerns for data center operators. In 2005, servers alone accounted for 1.2% of energy consumption in the U.S. [1]. By 2012, the EPA predicts energy consumption in data centers will double from 2007 levels. Energy prices are also increasing. In 2006, they rose by 10% [1]. Energy prices are expected to rise even higher, due to regulatory and social concerns over green house gas emissions from energy production. In this work, we demonstrate how data center energy consumption can be reduced and thermal capacity improved by systematically considering the interactions between data center infrastructure elements (e.g., cooling and servers). Specifically, we quantify the benefits of the automated migration of workloads running in Virtual Machines (VMs). VMs are migrated from a set of servers located in an inefficient thermal zone to servers in a more efficient zone. Our experimental results show that our technique reduced data center energy usage by 30% and improved available thermal capacity by 22%.
