Here, we present the first steps to build a process design kit of components in the visible range centered at 633 nm using a LPCVD silicon nitride platform. The first basic elements are presented (grating couplers, single mode waveguides and a MMI).
Tuning functional two-dimensional MXene nanosheets to enable efficient sulfur utilization in lithium-sulfur batteries (2021)

Practicality of lithium-sulfur batteries is severely hindered by the notorious polysulfide-shuttle phenomenon, leading to rapid capacity fade. This issue is aggravated with increase in sulfur loading, causing low-coulombic efficiency and cycle life. Herein, we present a facile strategy to combine hydrophobic sulfur and hydrophilic, conductive Ti3C2Tz-MXene via one-step surface functionalization using di(hydrogenated tallow)benzylmethyl ammonium chloride (DHT). The latter renders the Ti3C2Tz surface hydrophobic, making it readily dispersible in sulfur dissolved in a carbon disulfide (CS2) solvent. By evaporating the solvent, we conformally coat the DHT-Ti3C2Tz (DMX) with sulfur. The developed composite, with higher available active area, enables effective trapping of lithium polysulfides (LiPs) on the electroactive sites within the cathode, leading to improvement in electrochemical performance at higher sulfur loadings. The DMX/S cathodes function with high sulfur loading of ∼10.7 mg·cm−2 and deliver a stable areal capacity of ∼7 mAh·cm−2 for 150 cycles. Moreover, a DMX/S cathode in a pouch-cell configuration retains ∼770 mAh·g−1 after ∼200 cycles at 0.2C (85.5% retention). Ex situ studies elucidate the nature of the LiPs-MXene interaction and the effect of surface functionalization towards improved performance.

Base-catalysed depolymerization of lignins in supercritical water: Influence of lignin nature and valorisation of pulping and biorefinery by-products (2022)

Different lignins from different sources (hardwoods, softwoods and crop residues) and obtained as by-products of different processes such pulping or biorefining were depolymerized in alkaline supercritical water (SCW: 386 °C and 260 bar) in an intensified continuous process to produce high value-added compounds with low-molecular-weight in only 300 ms of reaction time. The products obtained were analysed to determine the yield, selectivity to monomers, chemical structure and molecular weight distribution. The char formation was low in most cases, but the proportion of heavy and light oils were variable upon the starting material used. The monoaromatics yield depends mostly on the type of lignin utilized being the non-wood biorefinery lignins less suitable for monomers production than the technical wood ones (13-8%). The monomer distribution depends on the biomass of origin and the pulping method. This technology is equally effective when directly treating a black liquor and better results are obtained if compared to the corresponding isolated lignin.
Resistance to antimicrobial agents and prevalence of R plasmids in Pasteurella multocida from swine (1991)

Twenty-nine field isolates of porcine Pasteurella multocida were characterized for their capsular and somatic types and were evaluated for their susceptibility to 10 antimicrobial agents. Plasmid DNA-screening experiments were conducted to determine whether a relationship existed between the presence of plasmids and antibiotic resistance. Field isolates of P multocida were susceptible to most of the antimicrobials tested, but all isolates were resistant to clindamycin. Eleven isolates of serogroup D were resistant to 1 or 2 antimicrobial agents. Resistance to sulfonamides and streptomycin was observed in 7 isolates. These isolates contained R plasmids conferring resistance to streptomycin and sulfonamides. The R plasmids belonged to 2 groups, one of 5.6 kilobase and the other of 5.9 kilobase. Restriction endonuclease mapping and DNA hybridization revealed that these R plasmids were related to RSF1010 from Salmonella panama, which also confers resistance to streptomycin and sulfonamides.
Solar‐Energy Harvesting: Broadband Hot‐Electron Collection for Solar Water Splitting with Plasmonic Titanium Nitride (Advanced Optical Materials 15/2017) (2017)

In article number 1601031, Alberto Naldoni, Vladimir M. Shalaev, and co-workers present plasmonic titanium nitride (TiN) nanoparticles on top of TiO2 nanowires, which strongly improve the activity toward photoelectrochemical water splitting. Plasmonic TiN provides efficient generation of hot electrons due to a broadband absorption and improved electrical compatibility at the TiN–TiO2 interface.
The heterogeneous decomposition of ozone on atmospheric mineral dust surrogates at ambient temperature (2006)

Abstract The rate of uptake of ozone on various mineral dust surrogates, expressed as uptake coefficient γ, has been studied employing a Knudsen flow reactor. Experiments were performed at T = 298 ± 2 K on substrates of kaolinite, CaCO 3 , natural limestone, Saharan dust, and Arizona test dust. Initially, the uptake coefficients have been calculated on the basis of the geometric surface area of the powder samples. Both initial and steady‐state uptake coefficients γ 0 and γ ss were found very similar for all the examined substrates. In addition, additional uptake experiments on marble sample have shown that γ 0 and γ ss may be overestimated between a factor of 50 and 100, respectively. Based on these considerations, we proposed initial and steady‐state uptake values of the order of 10 −4 and 10 −5 , respectively. On kaolinite, the uptake coefficient decreased with increasing O 3 residence time τ g thus indicating a complex mechanism. In contrast, γ decreased and became independent of τ g at long residence time after long exposure to O 3 . For all uptake experiments the disappearance of O 3 was accompanied by the formation of O 2 . The different mineral dust surrogates may be more accurately distinguished by their time‐dependent O 2 yield r ( t ) rather than the magnitude of γ. The heterogeneous reaction of O 3 on mineral dust has been found to be noncatalytic and of limited importance in the atmosphere. © 2006 Wiley Periodicals, Inc. Int J Chem Kinet 38: 407–419, 2006
Sleep-disordered Breathing in Heart Failure – Current State of the Art (2015)

Sleep-disordered breathing (SDB), either obstructive sleep apnoea (OSA) or central sleep apnoea (CSA)/Cheyne-Stokes respiration (CSR) and often a combination of the two, is highly prevalent in patients with heart failure (HF), is associated with reduced functional capacity and quality of life, and has a negative prognostic impact. European HF guidelines identify that sleep apnoea is of concern in patients with HF. Continuous positive airway pressure is the treatment of choice for OSA, and adaptive servoventilation (ASV) appears to be the most consistently effective therapy for CSA/CSR while also being able to treat concomitant obstructive events. There is a growing body of evidence that treating SDB in patients with HF, particularly using ASV for CSA/CSR, improves functional outcomes such as HF symptoms, cardiac function, cardiac disease markers, exercise tolerance and quality of life. However, conflicting results have been reported on 'hard' outcomes such as mortality and healthcare utilisation, and the influence of effectively treating SDB, including CSA/CSR, remains to be determined in randomised clinical trials. Two such trials (SERVE-HF and ADVENT-HF) in chronic stable HF and another in post-acute decompensated HF (CAT-HF) are currently underway.
Real-time dual-frequency (L1/L5) GPS/WAAS software receiver (2011)

This paper demonstrates a real-time software receiver supporting GPS/WAAS dual-frequency (L1/L5) processing. The software receiver is implemented on a widely-available recent generation multi-core processor and is capable of post-processing datasets from collection hardware. Key contributions of this software receiver are that 1) it is perhaps the first receiver capable positioning solely on L5 ranging despite there being only one operational GPS L5 signal and 2) it estimates ionosphere delay using L1-L5 measurements The architecture of such a software receiver needs to be carefully developed so that it can process signals from each individual frequency. Multitasking and synchronization mechanisms were developed to support the tracking of multiple channels in real time. To achieve real-time capability, parallel operations are necessary to reduce computation complexity. Bit-wise operations are exploited and implemented by Single Instruction Multiple Data (SIMD) instructions in the software correlator. An assistance mechanism between L1 and L5 is built for shortening the acquisition time and increasing the sensitivity of tracking L5 data-free channel. Currently, positioning using GPS/WAAS L5 signal needs assistance from L1 signal because the ephemeris on GPS L5 is currently not provided. However, using the L1 GPS ephemeris from L1 should consider the time offset or interfrequency bias (IFB) between L1 and L5 which results from the difference of antenna phase center and other hardware on the satellite. Besides, a time offset exists between WAAS and GPS time. These time offsets are solved by adding another unknown into position solution. The solutions of the time offset are used to correct the pseudorange of L5 and then perform positioning by three methods 1) L1 only 2) L5 only 3) iono-free combination. The results of positioning by the dual-frequency software receiver are illustrated and the positioning accuracy is analyzed in this paper.
Engineering a GPCR−Ligand Pair That Simulates the Activation of D2L by Dopamine (2009)

In the past decade, engineered G-protein-coupled receptors activated solely by synthetic ligands (RASSLs) have been implemented as a new means to study neurotransmission, which is controlled by G-protein-coupled receptors in vitro and in vivo. In this study, we report an engineered dopamine receptor D(2L) F390(6.52)W, which is the first identified RASSL for the dopamine receptor family. The mutant receptor is characterized by a disrupted ligand binding and complete loss of efficacy for the endogenous ligand, dopamine, which is putatively due to a sterically induced perturbation of H-bonding with conserved serine residues in TM5. Based on this model, we rationally developed an aminoindane-derived set of agonists. Because these agonists forgo analogous H-bonding functionalities, their binding energy does not depend on the respective interactions. Binding affinity and potency were optimized by ligand modifications bearing molecular appendages that obviously interact with a secondary recognition site provided by four hydrophobic residues in TM2 and TM3. Thus, the ferrocenyl carboxamide 5b (FAUC 185) was identified as a synthetic agonist that is able to stimulate the mutant receptor in a manner similar to that by which endogenous dopamine activates the D(2L) wild-type receptor. The engineered dopamine receptor D(2L) F390(6.52)W in combination with FAUC 185 (5b) provides a new tool to probe GPCR functions selectively in specific cell populations in vitro and in vivo.

Low complexity user pairing algorithm for in-band full-duplex networks with power control (2017)

Full Duplex(FD) network is considered as efficient scheme which could service both downlink(DL) and uplink(UL) users by same resource while HD can serve only DL or UL user for each resource. By optimized user scheduling with power control, optimal spectral efficiency could be achieved but optimization problem is non-linear and complex thus it is hard to implement. Low complexity relaxed optimization problem is proposed to solve resource allocation to minimize the transmission completion time in FD network. By adopting proposed scheme, suboptimal solution can be found in linear problem with significantly lower complexity.

The reliability of WDM transmission at 10 Gb/s on overhead fiber-optic cables, in the presence of lightning and short-circuit discharge events, has been proven by repeated laboratory tests, simultaneously evaluating BER, state-of-polarization and optical path evolutions
Introducing Information Technology Fundamentals Into The Undergraduate Curriculum (2020)

We have been challenged to introduce our students to "information technology" as part of their undergraduate education. This is not an exercise in training people how to use a word processor, rather it is teaching the undergraduate student, from any discipline, the underlying fundamentals of the technology which pervades our daily lives. The genesis of the course is a result from a survey of senior people at Navy operational commands listing the top ten areas where our graduates could use more emphasis in their education. Of those top ten, we developed a course, which addressed seven of the areas. These areas include Networking, the Internet, Communications Theory, Software, Databases and the World Wide Web. The diversity of the topics and the target audience meant that we were not able to go particularly deep in any one area. One of our main goals was to bring a non-technically oriented student up to a conversational level on the topic areas and to provide them with a foundation and a desire to seek a deeper understanding on their own. The initial target audience for the course is anyone who has had two semesters of Physics. As a result, we had ten different majors in the first offering of the course, varying from History to Economics to Computer Science and Marine Engineering. The course is offered as a lab course in order to allow as much hands-on opportunity as possible. In this paper, we focus on the course topics we covered in hope that others who may face this daunting challenge may gain some insight. We attempt to show how we approached some of the more complex topics without the benefit of higher order math emphasizing the importance of cooperative and collaborative learning in this environment. We also hope to show why a course like this rightly belongs in the Electrical and/or Computer Engineering Department and the challenges that brings.
Vibration analysis of drillstrings with string—borehole interaction (2008)

Drillstring vibration is one of the major causes for a deteriorated drilling performance, and if left untreated may result in a complete failure of the drilling process. Although the variations in the drilling load, stick-slip, and whirling are known to be the primary causes of severe vibrations, they often give rise to excessive flexural deformations and subsequent string—borehole interaction. Drillstring contact-impact interaction with borehole results in high-frequency excitations, which further deteriorate the drilling performance, and may cause damage to the bottomhole assembly. Modelling of impact is crucial to understanding the associated dynamic response, and to providing means for controlling the collision phenomenon. A continuous force—displacement law is introduced to model the impulsive force during the short-lived interval of impact, wherein the material compliance and damping coefficients are determined from energy balance relations. The impact model is integrated to the dynamic model of the whole drillstring; including drillpipes and drillcollars. The dynamic model of the rotating drillstring is formulated using a Lagrangean approach in conjunction with the finite-element method. The model accounts for the torsional-bending inertia coupling and the axial-bending geometric non-linear coupling. In addition, the model accounts for the gyroscopic effect and the effect of the gravitational force field. The generalized eigenvalue problem is solved to determine modal transformations, which are invoked to obtain the reduced-order modal form of the dynamic equations. The developed model is integrated into a computational scheme to calculate time-response of the drillstring system in the presence of string—borehole collisions.
High-power, high-efficiency digital polar doherty power amplifier for cellular applications in SOI CMOS (2016)

This paper presents a Digital Doherty Power Amplifier (DDPA) with high back-off efficiency. The main and peaking amplifiers are implemented in 180 nm CMOS SOI as Digital Power Amplifiers (DPAs) with 10 bit amplitude control. The Doherty combiner is implemented using external matching components on a PCB, with lumped elements synthesized to provide equivalent characteristics of impedance inverter and offset-line. Phase adjustment between main and peaking DDPAs allows optimization of efficiency. CW measurements for the DDPA at 900 MHz correspond to 33.1 dBm peak power with 55.5% efficiency. This is highest reported output power for CMOS Doherty amplifiers. The efficiency at 6 dB back-off reaches 52.5%.
Experimental Feasibility of the In-Drilling Alignment Method for Inertial Navigation in Measurement-While-Drilling (2010)

Conventional methods in horizontal drilling processes incorporate magnetic surveying techniques for determining the position and attitude of the bottom-hole assembly (BHA). This results in an increased weight of the drilling assembly, higher cost due to the use of nonmagnetic drill collars necessary for shielding the magnetometers, and significant errors in the position of the drilling bit. A novel inertial navigation system (INS)-based technique has been previously proposed as an alternative to magnetometer-based downhole surveying. Previous studies have shown theoretically that an adaptive-filter-based in-drilling alignment (IDA) fine alignment method successfully limits the error growth associated with INS. This study aims at examining IDA's practical feasibility and, specifically, its ability to estimate the azimuth angle. Experimental testing of the IDA method was conducted under laboratory conditions with an apparatus that can easily be adopted for downhole conditions. The experimental results demonstrate that the IDA-estimated azimuth is more precise, compared with the one estimated by conventional magnetic surveying systems. The high accuracy and implementation simplicity of the proposed INS-based surveying system render it a preferred method for future horizontal drilling operations.
Proteomic Analysis of Glomerular Proteins in Primary and Bucillamine-induced Membranous Nephropathy (2021)

Abstract The aim of this study was to characterize glomerular proteins in primary membranous nephropathy (pMN) and drug-induced secondary MN (sMN) by laser microdissection and comparative proteomic analysis. We used renal biopsy specimens from 6 patients with anti-phospholipase A2 receptor autoantibody (PLA2R Ab) (+) pMN, 6 patients with PLA2R Ab (‒) pMN, 6 patients with bucillamine (BCL)-induced sMN, and 5 control cases (time 0 transplant biopsies). Proteins were extracted from laser-microdissected glomeruli and analyzed using mass spectrometry. The quantification values of protein abundance in each MN group were compared with those in the control group. More than 800 proteins with high confidence were identified. Principal component analysis revealed a different distribution between the pMN and sMN groups. For further analysis, 441 proteins matched with ≥3 peptides were selected. Among the pMN and sMN groups, we compared the profiles of several protein groups based on the structural and functional characteristics, such as immunoglobulins, complements, complement-regulating proteins, podocyte-associated proteins, glomerular basement membrane proteins, and several proteins that are known to be associated with kidney diseases, including MN. Between the pMN and BCL-induced sMN groups, we observed common and different alterations in protein levels such as known disease-associated proteins and potential disease marker proteins.
Emmanuel Macron et les réformes territoriales. Finances et institutions (2020)

Emmanuel Macron n’a exercé aucun mandat local avant d’être élu président de la République. Cet évènement, unique dans l’histoire politique récente de notre pays, a été présenté par beaucoup de commentateurs comme le présage de ruptures à venir dans le cours de l’action publique vis-à-vis des « territoires ».\n\nLa singularité de son profil était elle-même renforcée par l’élection d’une majorité de député.es largement composée de nouvelles et nouveaux entrant.es, dépourvu.es d’ancrage territorial et de toute expérience des mandats locaux. Dans la mesure où il avait « en même temps » fait l’éloge de la verticalité supposément attendue des Français.es et proposé une approche fondée sur l’horizontalité, fallait-il attendre une inflexion significative du cours de l’action publique ?\n\nAlors que la dernière partie du quinquennat est engagée, cet ouvrage examine ce qu’il est réellement advenu de sa promesse de bâtir un « pacte girondin » avec les collectivités territoriales et leurs élu.es. Le pouvoir macronien a-t-il donné naissance à un mouvement de recentralisation, ainsi que le suggèrent ses opposants, ou au contraire, ouvert la voie à une relance de la décentralisation, comme le proclament les discours présidentiels ?\n\nQu’est-il advenu des perspectives de différenciation territoriale ébauchées durant la campagne et quelles en sont les traductions concrètes ?\n\nCe livre s’attache à comprendre et à analyser la politique territoriale d’Emmanuel Macron – politique dont l’importance est cruciale dans la perspective de 2022 – à travers neuf contributions rédigées dans un style accessible à tou.tes par des spécialistes de sociologie politique et de l’action publique territoriale.
