Continuous curvature path planning for semi-autonomous vehicle maneuvers using RRT (2015)

This paper proposes a sampling based planning technique for planning maneuvering paths for semi-autonomous vehicles, where the autonomous driving system may be taking over the driver operation. We use Rapidly-exploring Random Tree Star (RRT*) and propose a two-stage sampling strategy and a particular cost function to adjust RRT* to semi-autonomous driving, where, besides the standard goals for autonomous driving such as collision avoidance and lane maintenance, the deviations from the estimated path planned by the driver are accounted for. We also propose an algorithm to remove the redundant waypoints of the path returned by RRT*, and, by applying a smoothing technique, our algorithm returns a G <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> continuous path that is suitable for semi-autonomous vehicles. In order to deal with sudden changes in the environment, we apply a replanning procedure to enable our algorithm to rapidly react to the changes in a real-time manner, without full recomputation of the RRT* solution. Numerical simulations demonstrate the effectiveness of the proposed method.
An Opportunistic STBC-OFDM Scheme with Reduced PAR in the Presence of Frequency Offset (2007)

In [(S. Diggavi et al., 2003),(S. Das et al., 2005, 2006)] opportunistic space-time block codes were presented for flat-fading channels. In this paper, we propose an opportunistic STBC-OFDM for frequency-selective channels with an unequal error protection capability making it attractive for multimedia applications. Our new scheme optimizes the tradeoff between coding gain and peak-to-average ratio while minimizing inter-carrier interference in the presence of carrier frequency offset. We show that our scheme achieves a 2 dB reduction in PAR over the conventional scheme.
Push-to-Talk over LTE Modeling and Performance Evaluation (2019)

Public Safety organizations play a vital role in disaster recovery and public protection. First responders rely on their communication systems to perform their mission. Their communication systems are considered mission critical which puts special requirements on their underlying enabling technologies. Nowadays, most of the communication systems used in public safety are narrowband and were mainly developed for voice communication. Push-to-Talk is a multicast (group call) half-duplex type of communication that emergency first responders heavily rely on. When first responders request to speak by pushing the button on their handset, during emergencies, they must be confident that their requests will go through and not blocked. LTE technology has been chosen in many countries, including the US, to be the platform for the next generation public safety communication systems. LTE is a broadband wireless communication technology that public safety communication may benefit from the high data rates LTE technology offers. This paper proposes an analytical model of Push-to-Talk over LTE networks to study their performance by using queueing theory. The model is validated against a discrete event simulation (SimEvents). The study provides some guidelines to improve the Grade of Service (GOS) of Push-to-Talk over LTE systems.
Immune capacity of the chicken bursectomized at 60 hr of incubation: surface immunoglobulin and B-L (La-like) antigen-bearing cells. (1983)

Chickens were surgically bursectomized at 60 hr of incubation before the bursal anlage appears. Completeness of the bursectomy was confirmed at autopsy at 10 wk of age. These embryonically bursectomized (Bx) chickens are known to produce immunoglobulins of IgM, IgG, and IgA classes, but so far no specific antibodies have been observed even after heavy immunization. Regarding the appearance of surface immunoglobulin positive (s-Ig+) cells, the most striking effect of bursectomy was observed in the frequency of s-IgG+ cells, which were markedly decreased in the spleen, peripheral blood, and thymus of the Bx birds when compared with the age-matched controls. s-IgM+ cells were significantly decreased in the peripheral blood and s-IgA+ cells in the spleen of the Bx birds. In contrast to these findings, s-Ig+ cells of all three classes were present in normal frequency in the bone marrow. Bursectomy had no effect on the total lymphocyte and other white cell counts in the peripheral blood. Likewise, no effect on the frequency of B-L (Ia-like) antigen-positive cells in different organs was observed.
Conjugated Polymer- Based OFET Devices (2019)

Owing to their large-area and easy processing on flexible substrates, polymer thin film transistors (OTFT) have generated great interest for applications in displays, printed circuits or integrated sensors. Over the past years, advances have been made in designing novel classes of conjugated polymers routinely exhibiting benchmark field-effect (FET) mobilities above 1 cm2/Vs. For widespread applications in both scientific and industrial settings, however, there remain a range of challenges that still have to be overcome; these include understanding the role and origin of low environmental and stress stabilities, energetic disorder, device non-uniformity or the nonideality of device characteristics leading to an inflation of reported charge carrier mobilities. In this chapter, we review these challenges and look at what needs to be done for them to be to successfully addressed and overcome. We also take a look at state-of the-art polymer design concepts and review routes towards next generations of polymer OFET materials.
Des MEMS à l’optomécanique en cavité (2018)

Les travaux sur les microsystèmes mécaniques ont abouti à de nombreux succès techniques. Les technologies relatives aux capteurs inertiels sont désormais transférées à l’industrie, démontrant leur maturité. Ce domaine se renouvelle en intégrant la photonique et en exploitant les interactions de modes optiques résonants avec des modes de résonances mécaniques. Cette nouvelle approche aboutit à des preuves de concept de capteurs optomécaniques ultra sensibles ou de fonctions optiques nouvelles.
Diabetes exacerbates infection severity due to hyperinflammation rather than neutrophil defects (INM7P.425) (2014)

Abstract Patients with diabetes mellitus are at increased risk of dying from Gram negative bacterial infections. This excess mortality is often attributed to immune suppression, including neutrophil dysfunction. However, diabetic hosts also exhibit increased inflammatory responses to LPS. Here we show that lethal infections with Acinetobacter baumannii in diabetic mice are driven by LPS interactions with TLR4, as opposed to neutrophil defects. Mice made diabetic either by streptozotocin (Type 1) or diet induced obesity (Type 2) were hypersusceptible to lethality from A. baumannii bacteremia, whereas mice made neutropenic by anti-Ly6G administration were not more susceptible to infection. Diabetic infected mice developed severe septic shock, with hypothermia, medical acidosis, and marked elevations in inflammatory cytokines, compared to non-diabetic mice. Diabetic mice with impaired or absent TLR4 function, however, were protected against lethal infection and did not develop sepsis. Collectively, these results suggest that enhanced lethality of A. baumannii infection in diabetic mice is not driven by diabetes-related abrogation of neutrophil function. Rather, diabetic mice are more prone to progression to severe sepsis syndrome and are protected from this progression by impairment of TLR4 function. Short term abrogation of TLR4 signaling is a promising therapeutic approach to the treatment of A. baumannii, and possibly other Gram negative infections in diabetic hosts.
Can virtual-reality simulators assess experience and skill level of orthopaedic surgeons? (2015)

A summary of 16 recent construct validity studies is provided by this research which assesses evidence demonstrating whether virtual reality (VR) simulators can be used to assess and score the skill levels of orthopaedic surgeons. The findings of this study are that there is overwhelming evidence that VR simulators can reliably assess the skill levels of orthopaedic trainees, which suggests that VR training could potentially be used as part of a residency testing or assessment tool for orthopaedic surgery. This research provides an analysis of virtual reality orthopaedic simulator construct validity.
[Intra-cytoplasmic sperm injection with testicular sperm: what strategy?]. (1997)

The pregnancy rate after ICSI with surgically retrieved spermatozoa varies according to the etiology and to the level of sperm retrieval in the genital tract. The use of testicular sperm in all cases is discussed.
Spatial current-density instabilities in multilayered semiconductor structures (2002)

Semiconductor ${p}^{+}\ensuremath{-}{p}^{\ensuremath{-}}\ensuremath{-}n\ensuremath{-}{p}^{+}\ensuremath{-}{n}^{++}$ structures are considered as (1\ifmmode\times\else\texttimes\fi{}2)-dimensional active media. Such systems may exhibit several carrier injection modes associated with different nonequilibrium plasma/field patterns along the cathode-to-anode direction and numerous self-organized current-density patterns in the transversal plane. We study a peculiar field punch-through (FPT) mode by regarding the structure to be composed of two transistor subsystems coupled by a field domain. The suggested model allows one to analyze the stability properties of the uniform FPT mode with respect to transversal harmonic perturbations of the distributed variables. An analysis of the dispersion relations $\ensuremath{\zeta}(k)$ shows that depending on the material and design parameters three different types of instability may occur. The first one is of Ridley type, in which $\ensuremath{\zeta}$ first becomes positive for the lowest wave number $\stackrel{\ensuremath{\rightarrow}}{k}0.$ The second case corresponds to an analog of Turing's instability where the uniform state is destabilized by a fluctuation with a wave number $k&gt;0$ and being different from the lowest possible k value. Third, at certain conditions both types of instability may appear simultaneously, so that a new diversity of spatiotemporal patterns can be expected due to the competition between fluctuations with different wave numbers.

Overview of the OECD-NEA Working Party on International Nuclear Data Evaluation Cooperation (WPEC) (2020)

The OECD Nuclear Energy Agency (NEA) Working Party on International Nuclear Data Evaluation Cooperation (WPEC) was established in 1989 to facilitate collaboration in nuclear data activities. Over its thirty year history, different Subgroups have been created to address topics in nearly every aspect of nuclear data, including: experimental measurements, evaluation, validation, model development, quality assurance of databases and the development of software tools. WPEC has recently completed activities on fission yield evaluation, the general nuclear database structure (GNDS) to replace the ENDF-6 format, methods to provide feedback to evaluation, studies of specific capture cross sections, new methods in thermal scattering kernel evaluation and the Collaborative International Evaluated Library Organisation (CIELO) Pilot Project. Ongoing activities in GNDS application programming interface (API) development, methods for covariance evaluation and quality assurance in nuclear data validation using the International Criticality Safety Benchmark Evaluation Project (ICSBEP) database are complemented by the work of two Expert Groups that oversee the High-Priority Request List (HPRL) for Nuclear Data and the continuous development of the GNDS. New activities on the use of integral experiments for nuclear data validation and adjustment, as well as the use of the Shielding Integral Benchmark Archive and Database (SINBAD) for validation have begun and will be coordinated alongside future Subgroups. After three decades we will review the status of WPEC, how it integrates other collections and activities organised by the NEA and how it dovetails with the initiatives of the IAEA and other bodies to effectively coordinate international activities in nuclear data.
Mechanochemically Metamorphosed Composites of Homogeneous Nanoscale Silicon and Silicate Oxides with Lithium and Metal Compounds (2018)

An active anode material for Li-ion batteries was synthesized using a simple mechanochemical process to minimize the large change in Si volume observed during charge-discharge operation and to compensate for the associated irreversible loss of Li or irreversible capacity loss, which are obstacles to achieve high-performance electrochemical properties during charge-discharge. The composite was mechanochemically milled with Si, lithium oxide, and copper oxide as raw materials; the composite contains Si nanoparticles, amorphous silicon monoxide, and Si-Li or Si-Cu alloy compounds, and it exhibits improved electrochemical properties. In particular, this composite achieved a better capacity retention, higher coulombic efficiency (over 100%), and longer cycling performance than Si alone, indicating considerable optimization of the electrical and ionic conductivity in the composite. The developed method allowed for control of the Li content to compensate for the lack of Li ions in the composite, and the cycling performance was optimized using the Cu alloy, oxide, and Li compounds within the composite.
Gaussian mixture cardinalized PHD filter for ground moving target tracking (2007)

The cardinalized probability hypothesis density (CPHD) filter is a recursive Bayesian algorithm for estimating multiple target states with varying target number in clutter. In particular, the Gaussian mixture variant (GMCPHD) for linear, Gaussian systems is a candidate for real time multi target tracking. The present work addresses the following three issues: (i) we show the equivalence between the GMCPHD filter and the standard Multi Hypothesis Tracker (MHT) in the case of single targets; (ii) using a Gaussian sum approach, we extend the GMCPHD filter by employing digital road maps for road constraint targets. The utilization of such external information leads to more precise tracks and faster and more reliable target number estimates; (iii) we model the effect of Doppler blindness by a target state dependent detection probability, leading to more stable target number estimation in the case of low Doppler targets.
Bounce-by-Bounce Cavity Ring-Down Spectroscopy: Femtosecond Temporal Imaging (2001)

A time microscope (100× magnification) allows light pulses exiting an optical cavity to be viewed one at a time. A linearly chirped Gaussian pulse is mixed in a nonlinear crystal with the dispersed input waveform; the up-converted light is sent onto an output dispersive network. The resulting temporal image is recorded both with a streak camera and with a spectrometer.
Isolation of bacteriophage T4 baseplate proteins P7 and P8 and in vitro formation of the P10/P7/P8 assembly intermediate (1988)

Two bacteriophage T4 proteins, P7 and P8, which are components of the phage baseplate have been purified to apparent homogeneity. P7 and P8 are the protein products of T4 genes 7 and 8. A plasmid has been constructed which contains approximately 5 kilobases of T4 DNA, including genes 7 and 8, under the control of the tac promoter. Induction of Escherichia coli W3110iQ cells containing this plasmid resulted in the production of functional P7 and P8. Standard protein isolation procedures were used to purify both P7 and P8 from extracts of induced cells. In T4-infected cells, these two proteins and P10 interact in a strictly ordered sequential manner (P10 + P7----P10/P7,P10/P7 + P8----P10/P7/P8) to form an intermediate in the baseplate assembly pathway. The three purified proteins assembled in vitro to form a limited number of oligomeric species, as determined by nondenaturing gel electrophoresis. P10 and P7 interacted in vitro to form two assemblies with distinct electrophoretic mobilities, both containing P10 and P7. Addition of P8 to this mixture resulted in the disappearance of both P10/P7 species and the appearance of a single new assembly with a different electrophoretic mobility. These interactions occurred without the addition of any catalyst or cofactors. Isolated P11 appeared to add as predicted to the in vitro-formed complexes without affecting the formation of the two P10/P7 or the single P10/P7/P8 intermediates. Interactions between P7 and P8 in the absence of P10 or interactions between P10 and P8 in the absence of P7 could not be detected. These data indicate that purified P10, P7, and P8 interact in vitro in a manner completely in accord with the published assembly pathway and thus establish a system for further study of the regulation of the formation of this assembly intermediate in vitro.

Cell-specific transcriptional control of mitochondrial metabolism by TIF1γ drives erythropoiesis (2021)

Transcription and metabolism both influence cell function, but dedicated transcriptional control of metabolic pathways that regulate cell fate has rarely been defined. We discovered, using a chemical suppressor screen, that inhibition of the pyrimidine biosynthesis enzyme dihydroorotate dehydrogenase (DHODH) rescues erythroid differentiation in bloodless zebrafish <i>moonshine (mon)</i> mutant embryos defective for transcriptional intermediary factor 1 gamma (<i>tif1γ</i>). This rescue depends on the functional link of DHODH to mitochondrial respiration. The transcription elongation factor TIF1γ directly controls coenzyme Q (CoQ) synthesis gene expression. Upon <i>tif1γ</i> loss, CoQ levels are reduced, and a high succinate/α-ketoglutarate ratio leads to increased histone methylation. A CoQ analog rescues <i>mon</i>'s bloodless phenotype. These results demonstrate that mitochondrial metabolism is a key output of a lineage transcription factor that drives cell fate decisions in the early blood lineage.
Fabrication of TiB<SUB>2</SUB>/Al Composites by Combustion Synthesis of Al-Ti-B System (2002)

Aluminum matrix composites reinforced with TiB2 particles which were synthesized in situ by a combustion reaction between titanium and boron were fabricated from powder mixtures of Al, Ti and B . The combustion reaction was generated in the compacted powder mixtures with and without preheating by an ignitor. The influences of a powder mixing ratio, porosity and preheating of the compacted reactant on the combustion reaction for the Al–Ti–B system were experimentally investigated. The aluminum matrix composites including 30 to 60 vol%TiB2 could be fabricated by the combustion reaction without preheating, but some macroscopic cracks were occurred in the composites except for the Al–50 vol%TiB2. The relatively large porosity and preheating before the combustion reaction were effective to the self-propagation of the combustion reaction and microstructure of the synthesized composites, especially in the low volume fraction of TiB2. The reaction between titanium and boron in the Al–Ti–B system was initiated after the melting of aluminum.
Compatibility of behavior interconnections (2003)

In this paper we discuss the concept of compatible behavior interconnections. We distinguish the case where all variables are available for interconnection (total interconnection) from the case where only a part of them are (partial interconnection). The main idea behind the notion of compatibility for total interconnection is causality of (the effect of) the interconnection. We also show that state variables are closely related with the concept of compatibility. The concept of compatibility has been introduced for linear behaviors. In this paper, we propose an extension for the existing concepts. Relations between the proposed concept and the existing ones are also explained.
Direct gap photoluminescence and electroluminescence in Ge<inf>1&#x2212;y</inf>Sn<inf>y</inf> alloys (2011)

Direct-gap photoluminescence and electroluminescence has been observed in Ge <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1-y</sub> Sn <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">y</sub> alloys. The emission in both cases is dominated by direct transitions exhibiting the expected compositional dependence. The data are consistent with the expected reduction of the Γ-L separation.
GeV-scale electron acceleration in a gas-filled capillary discharge waveguide (2007)

We report experimental results on laser-driven electron acceleration with low divergence. The electron beam was generated by focussing 750mJ, 42 fs laser pulses into a gas-filled capillary discharge waveguide at electron densities in the range between 10^18 and 10^19 cm^-3. Quasi-monoenergetic electron bunches with energies as high as 500 MeV have been detected, with features reaching up to 1 GeV, albeit with large shot-to-shot fluctuations. A more stable regime with higher bunch charge (20-45 pC) and less energy (200-300 MeV) could also be observed. The beam divergence and the pointing stability are around or below 1 mrad and 8 mrad, respectively. These findings are consistent with self-injection of electrons into a breaking plasma wave.
A Radiolabeled Fully Human Antibody to Human Aspartyl (Asparaginyl) β -Hydroxylase Is a Promising Agent for Imaging and Therapy of Metastatic Breast Cancer (2017)

There is a need for novel effective and safe therapies for metastatic breast cancer based on targeting tumor-specific molecular markers of cancer. Human aspartyl (asparaginyl) β-hydroxylase (HAAH) is a highly conserved enzyme that hydroxylates epidermal growth factor-like domains in transformation-associated proteins and is overexpressed in a variety of cancers, including breast cancer. A fully human monoclonal antibody (mAb) PAN-622 has been developed to HAAH. In this study, they describe the development of PAN-622 mAb as an agent for imaging and radioimmunotherapy of metastatic breast cancer. PAN-622 was conjugated to several ligands such as DOTA, CHXA″, and DTPA to enable subsequent radiolabeling and its immunoreactivity was evaluated by an HAAH-specific enzyme-linked immunosorbent assay and binding to the HAAH-positive cells. As a result, DTPA-PAN-622 was chosen to investigate biodistribution in healthy CD-1 female mice and 4T1 mammary tumor-bearing BALB/c mice. The <sup>111</sup>In-DTPA-pan622 mAb concentrated in the primary tumors and to some degree in lung metastases as shown by SPECT/CT and Cherenkov imaging. A pilot therapy study with <sup>213</sup>Bi-DTPA-PAN-622 demonstrated a significant effect on the primary tumor. The authors concluded that human mAb PAN-622 to HAAH is a promising reagent for development of imaging and possible therapeutic agents for the treatment of metastatic breast cancer.
