Transient birefringence and dichroism in ZnO studied with fs-time-resolved spectroscopic ellipsometry (2021)

The full transient dielectric-function (DF) tensor of ZnO after UV-laser excitation in the spectral range 1.4-3.6 eV is obtained by measuring an m-plane-oriented ZnO thin film with femtosecond (fs)-time-resolved spectroscopic ellipsometry. From the merits of the method, we can distinguish between changes in the real and the imaginary part of the DF as well as changes in birefringence and dichroism, respectively. We find pump-induced switching from positive to negative birefringence in almost the entire measured spectral range for about 1 ps. Simultaneously, weak dichroism in the spectral range below 3.0 eV hints at contributions of inter-valence-band transitions. Line-shape analysis of the DF above the band gap based on discrete exciton, exciton-continuum, and exciton-phonon-complex contributions shows a maximal dynamic increase in the transient exciton energy by 80 meV. The absorption coefficient below the band gap reveals an exponential line shape attributed to Urbach-rule absorption mediated by exciton-longitudinal-optic-phonon interaction. The transient DF is supported by first-principles calculations for 10 20 cm -3 excited electron-hole pairs in ideal bulk ZnO.
J-FLiC UAS Flights for Acoustic Testing Research (2016)

The jet-powered flying testbed (J-FLiC) unmanned aircraft system (UAS) successfully completed twenty-six flights at Fort AP Hill, VA, from 27 August until September 3 2015, supporting tests of a microphone array system for aircraft noise measurement. The test vehicles, J-FLiC NAVY2 (N508NU), and J-FLiC 4 (N509NU), were flown under manual and autopiloted control in a variety of test conditions: clean at speeds ranging from 80 to 150 knots; and full landing configuration at speeds ranging from 50 to 95 knots. During the test campaign, autopilot capability was incrementally improved to ultimately provide a high degree of accuracy and repeatability of the critical test requirements for airspeed, altitude, runway alignment and position over the microphone array. Manual flights were performed for test conditions at the both ends of the speed envelope where autopiloted flight would have required flight beyond visual range and more extensive developmental work. The research objectives of the campaign were fully achieved. The ARMD Integrated Systems Research Program (ISRP) Environmentally Responsible Aviation (ERA) Project aims to develop the enabling capabilities/technologies that will allow prediction/reduction of aircraft noise. A primary measurement tool for ascertaining and characterizing empirically the effectiveness of various noise reduction technologies is a microphone phased array system. Such array systems need to be vetted and certified for operational use via field deployments and overflights of the array with test aircraft, in this case with sUAS aircraft such as J-FLiC.
Mapping and correcting hyperpolarized magnetization decay with radial keyhole imaging (2019)

We have demonstrated that center-out trajectories combined with keyhole reconstruction can be used to map regional HP signal decay and to quantitatively correct images. This approach may be used to improve the accuracy of quantitative measures obtained from hyperpolarized media. Although validated with gaseous HP <sup>129</sup> Xe in this work, this technique can be generalized to any hyperpolarized agent.
Control of SiC-based dual active bridge in high power three phase on-board charger of EVs (2015)

This paper presents a control algorithm of active power flow between traction battery and grid in a dual active bridge converter (DAB). Here, DAB is a part of a three phase 10kW bidirectional on-board charger in electric vehicles (EVs). It is an isolated interface to the battery placed after a three phase power factor correction (PFC) stage. 1200V rated SiC JFETs in the H-bridge at the DC link side of DAB enable operation at high voltage values of the DC link (above 500V) with high switching frequencies in the range from 50 to 150 kHz. Both high converter efficiency and simplified, compact converter design can be achieved thanks to the application of these wide band gap (WBG) devices. Furthermore, the control algorithm is presented to achieve the fast reference tracking even in the case when, due to simplicity of sensing, only average values of currents of both battery and DC link are being regulated.
II. The Effects of Some Hallucinogens on Aggressiveness of Mice and Rats (1972)

The action of JB-336, psilocybin, ibogaine and bufotenine on the aggressiveness os isolated mice, as well as the muricide reaction of rats, was investigated. All drugs evoked a substantial decrease in aggressiveness, but this effect was dependent on isolation time, time after injection and the type of test used.
Phenotypic and genotypic infidelity in B-lineage neoplasms, including transdifferentiation following targeted therapy: Report from the 2021 SH/EAHP Workshop (2023)

This cohort of cases enabled us to illustrate, discuss, and review current concepts of lineage switch and aberrant antigen expression in a variety of B-cell neoplasms and draw attention to the role targeted therapies may have in predisposing neoplasms to transdifferentiation as well as other, less expected changes in maturational status.
Scaling of flux pinning with the thermodynamic critical field (1999)

A systematic study of flux pinning and the thermodynamic critical field ${H}_{c}$ has been undertaken to determine whether ${H}_{c}$ is a central factor determining the critical current ${J}_{c}.$ Materials that have a fairly wide temperature interval of thermodynamic reversibility are selected so that the thermodynamic critical field can be confidently extrapolated into the irreversible regime. ${J}_{c}$ is found to scale with ${H}_{c}.$ For a given sample, the ${J}_{c}{/H}_{c}$ vs ${H/H}_{c}$ curves are close to a universal function as temperature changes. In addition, the peak in the pinning force curve also scales with ${H}_{c}^{2}$ for a wide variety of samples having quite different transition temperatures.
Association Between ABCB1 Polymorphism and Stable Warfarin Dose Requirements in Brazilian Patients (2018)

The ideal dose of the oral anticoagulant warfarin varies widely among patients, mainly due to genetic factors. Genetic variations that impact warfarin pharmacokinetics and the vitamin K cycle are plausible candidates for being associated with warfarin dose requirements. Therefore, the aim of this study was to assess whether polymorphisms in the <i>ABCB1</i> and <i>CYP4F2</i> genes were associated with stable warfarin dose requirements in Brazilian patients. This retrospective study included samples from 309 individuals. Genotyping of <i>ABCB1</i> c.3435C>T and <i>CYP4F2</i> c.1297G>A were performed by polymerase chain reaction followed by melting curve analysis (HRM-PCR) and TaqMan® genotyping assay, respectively. Stable doses were adjusted in a linear multiple regression model for age, gender, body mass index, self-reported race, use of amiodarone, <i>CYP2C9</i> (<sup>*</sup>2 and <sup>*</sup>3), <i>VKORC1</i> c.1639G>A, and <i>ABCB1</i> c.3435C>T or <i>CYP4F2</i> c.1297G>A. By performing a univariate analysis of variance, we found that the warfarin patients who carry <i>ABCB1</i> c.3435T variant alleles (CT and TT genotypes) need fewer warfarin stable doses in comparison with the individuals that are CC wild-type: 2.5 (<i>p</i> = 0.003) and 4.3 (<i>p</i> < 0.001) mg/week less, respectively, for the overall group of patients on stable anticoagulation therapeutics (<i>n</i> = 309); and 5.5 (<i>p</i> = 0.006) and 10.2 (<i>p</i> < 0.001) mg/week less, respectively, for the self-declared non-white stable subgroup (<i>n</i> = 76). No statistically significant differences in dose requirements were observed according to <i>CYP4F2</i> genotypes. In conclusion, our results suggest <i>ABCB1</i> c.3435C>T variant may influence warfarin dose requirements in Brazilian patients, when associated with other genotypic, demographic and clinical factors.
Digital image recording for court-related purposes (2003)

While the evidentiary value of photographs submitted with original film material (ordinarily a negative or slide) has rarely been contested in the past, it is likely that the susceptibility of digital images to manipulation will lead to increasing doubt with respect to the authenticity of photographic images in the era of digital data processing. Faced with this situation, it is essential that all concerned, and law-enforcement agencies in particular, engage in concerted world-wide efforts to preserve and restore the evidentiary value of photographic images. This article describes an approach to ensuring the integrity and authenticity of photographic images during the image-recording phase currently favoured by the Bundeskriminalamt. Because the retroactive detection of manipulations on the basis of image content alone is likely to prove quite difficult, this concept presently shows the most promise. Reflections regarding the basic configuration of a manipulation-proof digital camera capable of meeting the stringent integrity and authenticity requirements imposed for images presented as evidence in court are discussed. We propose the use of a suitable digital signature, a method that is also used in other cases for the purpose of establishing the binding legal character of a digital expression of intent, as an effective means of protecting digital images against manipulation. Features built into the camera make it relatively easy to record additional characteristic parameters of the image-production process.
A Review on Graph Database and its representation (2019)

Extensively, facts are represented characteristically as a table for the purpose of making it indexed with increased readability. Currently, the tendencies are altering as Graph databases are rapidly attaining popularity. Actually, it is appropiately termed as "the outlook of DBMS". The demonstration of facts within the procedure of a graph advances within the circumstances sound for the prearranged facts through a dynamic schema. This paper discusses the backbone of graph database as to why they are gaining much popularity in present situations illustrating the dissimilar types available and their distinction. Owing to the extensive usage of graph algorithms with models, neither a standardised system nor query language has been dispossessed with graph databases. Research and industry acceptance will regulate the upcoming course of graph databases. The authors have tried in representing the graph database with a real life scenario.
Neuroradiology, Third Edition. Juan M. (1997)

Neuroradiology, Third Edition. Juan M. Taveras, John Pile-Spellman. Baltimore, Williams & Wilkins, 1996. Pages: 1179. Price:$200. ISBN: 0-683-08112-8. This is the third edition of what has become one of the classic textbooks of neuroradiology written by one of the foremost pioneers in the field. Since the publication of the second edition, the third edition has been extensively revised to provide an up-to-date overview of neuroradiology, including the most recent advances in imaging technology. What is most impressive is that the bulk of this book has been written by one author.

In addition, each chapter is presented in a highly organized fashion, which includes an overview at the beginning of each chapter detailing the major topics to be covered. Taveras' clarity is particularly evident in explanations of imaging physics in Chapter 2, which...
Neuropilin-1 is essential for vascular endothelial growth factor A–mediated increase of sensory neuron activity and development of pain-like behaviors (2023)

Neuropilin-1 (NRP-1) is a transmembrane glycoprotein that binds numerous ligands including vascular endothelial growth factor A (VEGFA). Binding of this ligand to NRP-1 and the co-receptor, the tyrosine kinase receptor VEGFR2, elicits nociceptor sensitization resulting in pain through the enhancement of the activity of voltage-gated sodium and calcium channels. We previously reported that blocking the interaction between VEGFA and NRP-1 with the Spike protein of SARS-CoV-2 attenuates VEGFA-induced dorsal root ganglion (DRG) neuronal excitability and alleviates neuropathic pain, pointing to the VEGFA/NRP-1 signaling as a novel therapeutic target of pain. Here, we investigated whether peripheral sensory neurons and spinal cord hyperexcitability and pain behaviors were affected by the loss of NRP-1. Nrp-1 is expressed in both peptidergic and nonpeptidergic sensory neurons. A CRIPSR/Cas9 strategy targeting the second exon of nrp-1 gene was used to knockdown NRP-1. Neuropilin-1 editing in DRG neurons reduced VEGFA-mediated increases in CaV2.2 currents and sodium currents through NaV1.7. Neuropilin-1 editing had no impact on voltage-gated potassium channels. Following in vivo editing of NRP-1, lumbar dorsal horn slices showed a decrease in the frequency of VEGFA-mediated increases in spontaneous excitatory postsynaptic currents. Finally, intrathecal injection of a lentivirus packaged with an NRP-1 guide RNA and Cas9 enzyme prevented spinal nerve injury-induced mechanical allodynia and thermal hyperalgesia in both male and female rats. Collectively, our findings highlight a key role of NRP-1 in modulating pain pathways in the sensory nervous system.
Topology, design, analysis and thermal management of power electronics for hybrid electric vehicle applications (2008)

Power electronics circuits play an important role in the success of electric, hybrid and fuel cell vehicles. Typical power electronics circuits in hybrid vehicles include electric motor drive circuits and DC/DC converter circuits. Conventional circuit topologies, such as buck converters, voltage source inverters and bidirectional boost converters are challenged by system cost, efficiency, controllability, thermal management, voltage and current capability, and packaging issues. Novel topologies, such as isolated bidirectional DC/DC converters, multilevel converters, and Z-source inverters, offer potential improvement to hybrid vehicle system performance, extended controllability and power capabilities. This paper gives an overview of the topologies, design, and thermal management, and control of power electronics circuits in hybrid vehicle applications.
DRD4 Genotype Predicts Longevity in Mouse and Human (2013)

Longevity is influenced by genetic and environmental factors. The brain's dopamine system may be particularly relevant, since it modulates traits (e.g., sensitivity to reward, incentive motivation, sustained effort) that impact behavioral responses to the environment. In particular, the dopamine D4 receptor (DRD4) has been shown to moderate the impact of environments on behavior and health. We tested the hypothesis that the DRD4 gene influences longevity and that its impact is mediated through environmental effects. Surviving participants of a 30-year-old population-based health survey (N = 310; age range, 90-109 years; the 90+ Study) were genotyped/resequenced at the DRD4 gene and compared with a European ancestry-matched younger population (N = 2902; age range, 7-45 years). We found that the oldest-old population had a 66% increase in individuals carrying the DRD4 7R allele relative to the younger sample (p = 3.5 × 10(-9)), and that this genotype was strongly correlated with increased levels of physical activity. Consistent with these results, DRD4 knock-out mice, when compared with wild-type and heterozygous mice, displayed a 7-9.7% decrease in lifespan, reduced spontaneous locomotor activity, and no lifespan increase when reared in an enriched environment. These results support the hypothesis that DRD4 gene variants contribute to longevity in humans and in mice, and suggest that this effect is mediated by shaping behavioral responses to the environment.
Ultrasonic focusing and steering through the skull: Toward brain imaging (1998)

The time-reversal method has been experimentally applied to the focusing through the skull bone. This technique needs the knowledge of the Green’s function of a dominant scatterer available in the medium. Moreover, it is shown that the skull induces severe attenuation of ultrasound and reduces the efficiency of the time-reversal approach. Nevertheless, an improvement of time-reversal processing for ultrasonic waves focusing through an aberrating and absorbing layer can be achieved. When the attenuating layer is located close to the array, this method consists of inversing the amplitude modulation before the time-reversal operation. Conversely, when the attenuating layer is located some distance away from the transducer array, numerical backpropagation is used to discriminate between the amplitude modulations resulting, respectively, from interference and absorption. Moreover, although time reversal is only self-adaptative to the artificial source implanted inside the imaging volume, this method is generalized to steer the ultrasonic beam on other points surrounding this acoustic source. This process has already been applied to hyperthermia through the skull bone and it can be applied to noninvasive brain imaging.

Extraction of essential oils with carbon dioxide (1993)

Abstract The use of compressed carbon dioxide to extract essential oils from primary botanicals has been an established practice for ten years. The technology involves high pressures and low temperatures in an energy efficient process which is environmentally friendly because the source of CO 2 is a by‐product of fermentations, not combustion of fossil fuels. A comparative study of steam‐distillation and CO 2 ‐extracted essential oils of celery seed ( Apium graveolens L.), hop ( Humulus lupulus L.), clove bud ( Syzygium aromaticum (L.) Merill. et L. M. Perry), juniper berry ( Juniperus communis L.), mace ( Myristica fragrans Houtt.), and ginger ( Zingiber officinale Roscoe) is made using free choice odour profiling and standardized fingerprint GLC analysis.
Three steps is all you need: fast, accurate, automatic scaling decisions for distributed streaming dataflows (2018)

Streaming computations are by nature long-running, and their workloads can change in unpredictable ways. This in turn means that maintaining performance may require dynamic scaling of allocated computational resources.Some modern large-scale stream processors allow dynamic scaling but typically leave the difficult task of deciding how much to scale to the user. The process is cumbersome, slow and often inefficient. Where automatic scaling is supported, policies rely on coarse-grained metrics like observed throughput, backpressure, and CPU utilization. As a result, they tend to show incorrect provisioning, oscillations, and long convergence times.We present DS2, an automatic scaling controller for such systems which combines a general performance model of streaming dataflows with lightweight instrumentation to estimate the true processing and output rates of individual dataflow operators.We apply DS2 on Apache Flink and Timely Dataflow and demonstrate its accuracy and fast convergence. When compared to Dhalion, the state-of-the-art technique in Heron, DS2 converges to the optimal, backpressure-free configuration in a single step instead of six.
Influence of warm-up duration and recovery interval prior to exercise on anaerobic performance (2016)

The purpose of the study was to determine the impact of different active warm-up (AWU) durations and the rest interval separating it from exercise on anaerobic performance. Eleven male physical education students (22.6 ± 2.52 years; 179.2 ± 4.3 cm; 82.5 ± 9.7 kg; mean ± SD) participated in a cross-over randomized study, and they all underwent the Wingate test after three AWU durations: 5 min (AWU5), 15 min (AWU15) and 20 min (AWU20), with recovery (WREC) or without a recovery interval (NREC) separating the AWU and anaerobic exercise performance. All the AWUs consisted of pedalling at a constant pace of 60 rpm at 50% of the maximal aerobic power. The rest interval between the end of warm-up and the beginning of exercise was set at 5 min. During the Wingate test, peak power (PP), mean power (MP) and the fatigue index (FI) were recorded and analysed. Oral temperature was recorded at rest and at the end of the warm-up. Likewise, rest, post-warm-up and post-Wingate heart rate (HR) and rating of perceived exertion (RPE) were recorded during each session. The ANOVA showed a significant effect of recovery interval, warm-up duration and measurement point on RPE scores (P<0.001). Although the effect of AWU duration on MP and PP was significant (P<0.05), the effect of the recovery interval on both parameters was not significant (P>0.05). Moreover, the analyses showed a significant interaction between recovery interval and AWU duration (P<0.001 and P<0.05 for MP and PP respectively). The AWU15 duration improves the MP and PP when associated with a recovery interval prior to exercise of 5 min. However, the AWU5 duration allows better improvement of power output when the exercise is applied immediately after the warm-up. Consequently, physically active males, as well as educators and researchers interested in anaerobic exercise, must take into account the duration of warm-up and the following recovery interval when practising or assessing activities requiring powerful lower limb muscle contractions.
Online Synchronization of Building Model for On-Site Mobile Robotic Construction (2020)

Online Synchronization of Building Model for On-Site Mobile Robotic Construction Selen Ercan Jenny, Hermann Blum, Abel Gawel, Roland Siegwart, Fabio Gramazio and Matthias Kohler Pages 1508-1514 (2020 Proceedings of the 37th ISARC, Kitakyushu, Japan, ISBN 978-952-94-3634-7) Abstract: This research presents a novel method for a data flow that synchronizes building information with the robot map and updates building components to their "as-built" states, in order to facilitate an on-site mobile construction process. Our experiments showcase mobile mapping and localization of a robotic platform featuring segmentation, plane association and quantitative evaluation of deviations. For the users of the on-site mobile robotic system, we present a suitable interface that allows for task level commanding and the selection of target and reference building components (i.e. walls, floor, ceiling). Additionally, this interface seamlessly integrates the online workflow between building construction and the robot map, updating the target building components to their "as-built" states in real time and providing a visual representation of additional task-specific attributes for building components in the robot map, in addition to geometries. This is presented as a first step toward integrating users of the system into the proposed robotic workflow to develop decisionmaking strategies for fitting building tasks to local references on-site.
