Energy storage solution for wireless sensor network used in bridge surface corrosion monitoring (2019)

This Letter presents a radio‐frequency energy storage solution for monitoring corrosion on bridge in wireless sensor network system. In this monitoring system, wireless terminals and sensors are installed on the bridges to monitor surface corrosion remotely. The proposed energy storage module to supply power to the sensors consists of a rectifier, a supercapacitor, and a DC–DC boost converter. The rectifier circuit is designed to convert 920 MHz RF energy to DC source. Experimental results demonstrate that the harvested energy can power up the sensor nodes for several times in a week, at input power density of 0.81 μW/cm 2 .

Stereochemical Observations in the Synthesis of Novel 1,4,5,9b-Tetrahydro-5-phenyl-2H-azeto[2,1-a]isoquinolin-2-one Derivatives (1993)

Imine (5),4-phenyl-3,4-dihydroisoquinoline, reacted with Cl 2 CHC(O)Cl in the presence of Et 3 N to give β-lactams, azeto[2,1-a]isoquinolin-2-one derivatives, (7a) and (7b) in a 4:1 ratio. The stereochemistry of cycloadduct (7a) was confirmed by X-ray analysis. Uncyclized intermediates were identified. Reduction of dichloro β-lactam (7a) with Zn/HOAc gave mostly exo monochloride (13a), with high stereoselectivity (10:1) ratio. Reduction of a mixture of exo and endo monochlorides (13a) and (13b) with Zn/HOAc indicated that the more sterically hindered endo chlorine is preferentially attacked. Reduction of (7a) with Bu 3 SnH gave β-lactam (14a) as the major product

On the measurement of the delta Radar Cross Section (&#x0394;RCS) for UHF tags (2009)

This paper presents a methodology for the practical measurement of the variation of the radar cross section for the RFID UHF tags. This is a very critical parameter, and will govern the tag performance. It also influences both the reading distance as well as the sensitivity of UHF tag. The paper includes the analysis procedure and the experimental setup. The later is based on standard equipments such as an anechoic environment, a vector signal generator and a vector signal analyzer. The application of the proposed method is illustrated on some samples of EPC GEN2 UHF tag. The delta RCS is obtained as a function of the reader power.
Asymmetric Electrophilic Fluorocyclization with Carbon Nucleophiles (2013)

Twist of ‘F'ate: Various helical-shaped fluorinated tetracyclic molecules were prepared by fluorocarbocyclization of prochiral alkenes. The development of a new class of chiral Selectfluor (1) proved instrumental in developing an asymmetric variant of this transformation. These novel chiral N-F reagents are readily accessible by fluorine transfer from shelf-stable N-fluoropyridinium salts.
A novel method of ligand peptidomics to identify peptide ligands binding to AQP2-expressing plasma membranes and intracellular vesicles of rat kidney (2008)

Aquaporin-2 (AQP2), the vasopressin-regulated water channel in collecting duct principal cells, plays a key role in the regulation of body water balance. We aimed to isolate high-affinity peptide ligands that bind to immunoisolated AQP2-expressing plasma membrane (PM) or intracellular vesicle (ICV) preparations from rat kidney by the in vitro phage display technique. Immunoblotting revealed that AQP2 was exclusively expressed in the immunoisolated AQP2 membrane fractions (PM and ICV), compared with the nonimmunoisolated or preimmune IgG pulldown rat kidney samples. Moreover, AQP1 or H+-ATPase (B1 subunit) expression was minimal in the immunoisolated AQP2 membrane fractions, indicating the specificity of AQP2 membrane isolation. A phage peptide library based on T7 415-1b phage vector displaying CX7C was constructed. After three rounds of biopanning, seven phage clones of high frequency were selected, which showed high affinity to the AQP2-containing PM or ICV fractions compared with a nonrecombinant T7 insertless phage clone. In contrast, these phage clones showed lower affinity to H+-ATPase-containing fractions. Fluorescein-conjugated peptide labeling was associated with intracellular compartment and PM of primary cultured inner medullary collecting duct cells, relative to absent or very weak labeling with fluorescein-conjugated control peptide. Library analyses demonstrated proteins that had motifs homologous to the peptide ligands, albeit with a high probability of a random match due to short peptide sequences. In summary, we applied the in vitro phage display technique to identify high-affinity peptide ligands to AQP2-expressing membranes. Library analyses identified proteins having homologous motifs, which need to be examined for involvement in AQP2 trafficking and regulation.
Comparison of Superpulse Thulium Fiber Laser vs Holmium Laser for Ablation of Renal Calculi in an In Vivo Porcine Model (2022)

<b><i>Introduction and Objectives:</i></b> We sought to compare the effectiveness and efficiency of the superpulse thulium fiber laser (sTFL to the holmium: yttrium-aluminum-garnet [Ho:YAG] laser for ureteroscopic "dusting" of implanted renal stones in an <i>in vivo</i> porcine model. <b><i>Methods:</i></b> Twenty-four porcine kidneys (12 juvenile female Yorkshire pigs) were randomized to Ho:YAG or sTFL treatment groups. Canine calcium oxalate stones were scanned with computed tomography to calculate stone volume and stone density; the stones were randomized and implanted into each renal pelvis via an open pyelotomy. In all trials, a 14F, 35 cm ureteral access sheath was placed. With a 9.9F dual lumen flexible ureteroscope, laser lithotripsy was performed using <i>dusting</i> settings: Ho:YAG 200 μm laser fiber at 16 W (0.4 J, 40 Hz) or sTFL 200 μm laser fiber at 16 W (0.2 J, 80 Hz). Lithotripsy continued until no fragments over 1 mm were observed. No stone basketing was performed. Throughout the procedures, intrarenal and renal pelvis temperatures were measured using two percutaneously positioned K-type thermocouples, one in the upper pole calyx and one in the renal pelvis. After the lithotripsy, the ureteropelvic junction was occluded, the kidneys were bivalved, and all residual fragments were collected, dried, weighed, and then measured with an optical laser particle sizer. <b><i>Results:</i></b> Implanted stones were similar in volume and density in both groups. Intraoperative collecting system temperatures were similar for both groups (all <44°C). Compared to Ho:YAG, sTFL ablated stones faster (9 <i>vs</i> 27 minutes, <i>p</i> < 0.001) with less energy expenditure (8 <i>vs</i> 26 kJ, <i>p</i> < 0.001), and a greater stone clearance rate (73% <i>vs</i> 45%, <i>p</i> = 0.001). After sTFL lithotripsy, 77% of the remaining fragments were ≤1 mm <i>vs</i> 17% of fragments ≤1 mm after Ho:YAG treatment (<i>p</i> < 0.001). <b><i>Conclusions:</i></b> In an <i>in vivo</i> porcine kidney, using <i>dusting</i> settings, sTFL lithotripsy resulted in shorter ablation times, higher stone clearance rates, and markedly smaller stone fragments than Ho:YAG lithotripsy.
Method of Minimizing Liner Expansion Issues in Horizontal Thermal Applications (2011)

Abstract Thermal recovery methods used in the exploitation of heavy-oil and bitumen reservoirs can create severe expansion problems on liner and production tubular equipment caused by the effects of thermal expansion. This is more often the case when using horizontal sandface completion configurations in steam flood, cyclic steam, and steam-assisted gravity drainage (SAGD) applications. Many single lateral and multi-lateral horizontal heavy-oil wells are produced initially using cold ambient reservoir heavy-oil production methodologies where liner expansion is not a concern. However, with proper up-front planning and engineering, these wells could be converted to thermal EOR producers with the addition of thermal expansion devices placed within the liner assembly when initially completed. These expansion devices are engineered to activate when exposed to elevated temperatures once the thermal operations begin and do not require mechanical activation or well intervention. Since these devices are deployed with the liner assembly, they must also be capable of handling compression, tension, and torque loading across the liner during the deployment phase. These devices can be deployed with the slotted liner/sand screen applications or can be used with production or concentric tubing configurations. This paper will present use of this new device in different wellbore configurations found in various thermal recovery methods.
Considerations on the Systematics of Neotropical Pierina, with the Description of Two New Species of Phulia Herrich-Schäffer from the Peruvian Andes (Lepidoptera: Pieridae, Pierinae, Pierini) (2022)

A comparative analysis of high-Andean Pierina was carried out, including a total of 25 species. Based on morphological evidence, with an emphasis on venation and genitalia and molecular data, using three genetic markers, we confirm the recent subjective synonymy of the generic names Tatochila Butler, 1870, Piercolias, Staudinger, 1894, Hypsochila Ureta, 1955, Infraphulia Field, 1958, Pierphulia Field, 1958, and Theochila Field, 1958 with Phulia Herrich-Schäffer, 1867. Two new species are described, namely Phulia stoddardi Pyrcz & Cerdeña n. sp., from the Andes of Central Peru, which occurs at an unusually high altitude of close to 5000 m a.s.l. in dry puna habitat, and Phulia phantasma Lamas, Willmott & Boyer n. sp., from dry montane forests in northern Peru and southern Ecuador. An overview of high-elevation butterflies is presented, with some discussion on adaptations to this environment.
A 2 Tb/s 6<formula formulatype="inline"><tex Notation="TeX">$\,\times\,$</tex> </formula>4 Mesh Network for a Single-Chip Cloud Computer With DVFS in 45 nm CMOS (2011)

A packet-switched 6 × 4 2-D mesh network providing 2 Tb/s of bisectional bandwidth with a per-hop latency of 4-cycles, forms the high performance communication fabric for a Single-Chip Cloud Computer (SCC) with 48 Pentium™ class IA-32 cores. The fabric operates on an independent power supply and frequency domain. The router micro-architecture achieves over 90% network utilization by effective use of a single-cycle Wrapped Wave-Front Allocator (WWFA) and virtual channel (VC) flow control. A router transit latency of 2 ns is achieved through early buffer write, route pre-computation and a single-cycle WWFA implementation. This 640 K transistor, 1.32 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> router operates at 2 GHz at 1.1 V while dissipating 550 mW. The 24-node mesh network with 1.28 Tb/s router and 16B, 5.4 mm wide links consumes only 5% of the chip area, 1.2% of the transistors and 10% of total chip power at 1.1 V in a 45 nm nine-metal CMOS process. The router energy efficiency scales from 1.3 Tb/s/W to 7.2 Tb/s/W over a dynamic voltage range from 0.7 V to 1.25 V.

The Moving Bed Fuel Reactor Process (2018)

This chapter describes the use of moving reactors for chemical looping processes with specific application to syngas and power production with CO2 capture using metal oxide materials as oxygen carrier chemical intermediates. The fuel reactor can be operated in counter-current or co-current moving bed mode, where the solid oxygen carrier particles travel downwards by gravity while the process gases flow upwards or downwards. The chapter discusses the development of the counter-current moving bed fuel reactor systems of the syngas chemical looping (SCL) and coal direct chemical looping (CDCL) processes for H2 production and power generation with CO2 capture, respectively. In the co-current moving bed fuel reactor operation, the gas species travel in the same directions as the solid flow. Co-current moving bed reactor system is directed for partial oxidation of solid and gaseous fuels to syngas. The chapter explores reactor thermodynamic modeling combined with experimental results.
Update to Terwilliger and Göring's “Gene Mapping in the 20th and 21st Centuries” (2000): Gene Mapping When Rare Variants Are Common and Common Variants Are Rare (2009)

Our Lasker Prize winning article from 2000 was a discussion of the myriad factors that influence the success or failure of gene mapping studies, and in it we sug- gested that the reasons we geneticists have had so little success in unraveling the etiology of complex traits had more to do with biology than technology and that many of the decisions about future strategies were being made based on unrealis- tic and untested assumptions. At the time, the common variant/common disease (CVCD) hypothesis (Reich and Lander 2001) was widely believed to provide a
Clinical manifestations of African AIDS. (1993)

This article provides a brief introduction to the problems posed by AIDS and AIDS-related conditions and their recognition.
A simple derivation of the constrained multiple parameter Cramer-Rao bound (1993)

J.D. Gorman and A.O. Hero (1988) obtained a remarkable extension to the classical multiple parameter Cramer-Rao (CR) lower bound that accounts for deterministic nonlinear equality constraints on the parameters. The virtue of Gorman and Hero's result is that the constrained CR bound on all of the parameters is obtained by subtracting an easily computed nonnegative definite correction matrix from the unconstrained CR bound matrix. The author presents a new, simple derivation of the constrained CR bound and a new necessary condition for an estimator to satisfy the constrained CR bound with equality.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Extensible packet processing architecture (2023)

A technique for distributed packet processing includes sequentially passing packets associated with packet flows between a plurality of processing engines along a flow through data bus linking the plurality of processing engines in series. At least one packet within a given packet flow is marked by a given processing engine to signify by the given processing engine to the other processing engines that the given processing engine has claimed the given packet flow for processing. A processing function is applied to each of the packet flows within the processing engines and the processed packets are output on a time-shared, arbitered data bus coupled to the plurality of processing engines.

Time-saving opportunities in knee osteoarthritis: T2 mapping and structural imaging of the knee using a single 5-min MRI scan (2019)

• Quantitative T<sub>2</sub>values of cartilage and meniscus as well as structural assessment of the knee with a single 5-min quantitative double-echo steady-state (qDESS) scan can distinguish between different grades of knee osteoarthritis (OA). • Quantitative and structural qDESS-based measurements correlate significantly with the reference standard, radiographic degree of OA, for all cartilage and meniscus regions. • By providing quantitative measurements and diagnostic image quality in one rapid MRI scan, qDESS has great potential for application in large-scale clinical trials in knee OA.
Current Practice: Diagnosis and Treatment in Primary Healthcare (1995)

In a primary healthcare facility, there are certain 'rules of thumb' that can be recommended for the diagnosis and treatment of conjunctivitis. The type of discharge is a crucial factor in the differential diagnosis and can also be a clue towards the management in primary care. It is important to identify whether the conjunctivitis is an isolated case or part of another disease, and if it is acute or chronic, and I would suggest taking a smear or culture sample whenever possible. When the aetiology is not clear, I would try antibiotics. If the patient is allergic, and an allergic conjunctivitis is suspected, the best management today is to use mast cell stabilisers, and combine these with conservative measures of frequent washings, and compresses. If the aetiology remains doubtful, or if there is no obvious improvement using these treatments, the patient should be re-evaluated and/or referred to an ophthalmologist or specialist eye centre. The use of corticosteroids for conjunctivitis should certainly be avoided in primary healthcare. Conjunctivitis is often self-limited and the drug-induced consequences of improper management can be far more devastating than the disease itself.
A Comprehensive Characterization of Hollow Conductor Additively Manufactured Coils and Thermal Management System for a 250kW SPM Machine (2022)

This paper provides an extensive and comprehensive analysis on characterization of additively manufactured coils and heat pipe based liquid cooling thermal management system, for a 250 kW and 5,000 rpm machine. AC and DC electrical tests at 140 Arms and 70 ADC are conducted on AlSi10Mg additively manufactured coils to extract their thermal and electrical characteristics. Heat pipes and liquid cooling test setups are described and discussed. The thermal discussion is concluded by experimental results showing the effectiveness of the thermal management system proposed in this paper. FEA are performed on the coils using ANSYS Maxwell to accurately predict the losses at frequencies and current levels where the experimental setups face limitations. The FEA calibration process is successfully implemented to match experimental results resulting in a maximum error of 2.4%. Moreover, the FEA results are used to predict experimental losses for the coils at 1250 Hz which is beyond the experimental setup limits.
Time domain cyclic-selective mapping for PAPR reduction using delayed correlation with matched filter in OFDM system (2015)

The cyclic-SLM which implements delayed correlation with a matched filter (DC-MF) is proposed in this paper. The cyclic-SLM reduces a peak-to-average power ratio (PAPR) on an orthogonal frequency divison multiplexing (OFDM) signal. This scheme combines the original OFDM signal and its cyclic shifted ones. However, it needs side information (SI) of the cyclic shifts to recover the original signal that decreases the throughput of a wireless OFDM system. The DC-MF estimates the amount of a shift in a receiver side by multipling a recieved signal with its conjugates of the guard interval (GI) sequence in the time domain. Numerical results obtained through computer simulation show that the cyclic-SLM with the DC-MF significantly reduces the PAPR by around 2.5 dB as compared to the original signal. It also achieves the accuracy rate of the amount of the shift close to 100 % and the BER of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−4</sup> at E <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">b</inf> /N <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</inf> = 8.8 dB that is close to the perfect shift estimation.

Structure-Based Optimization of a Fragment-like TLR8 Binding Screening Hit to an In Vivo Efficacious TLR7/8 Antagonist (2022)

Inappropriate activation of TLR7 and TLR8 is linked to several autoimmune diseases, such as lupus erythematosus. Here we report on the efficient structure-based optimization of the inhibition of TLR8, starting from a co-crystal structure of a small screening hit. Further optimization of the physicochemical properties for cellular potency and expansion of the structure-activity relationship for dual potency finally resulted in a highly potent TLR7/8 antagonist with demonstrated <i>in vivo</i> efficacy after oral dosing.
