Learning Based Security for VANET with Blockchain (2018)

The security issue is one of the greatest challenges in vehicular ad hoc networks (VANETs) attracting a great deal of attention. Malicious onboard units (OBUs) can attack other OBUs with various manners to obtain illegal gains, such as jamming, eavesdropping spoofing and so on. To reduce the potential attackers in the network, we propose an indirect reciprocity security framework with a scalar reputation assigned to each OBU to evaluate their dangerous level to the VANET. A blockchain technique that uses consensus mechanism and encryption algorithms to protect information from being tampered is applied for the transmitter to record the behaviors of other OBUs. We also propose a reinforcement learning based action selection strategy for an OBU in the VANET to choose a reliable relay OBU or determine whether to follow the request of a source OBU or not. A hotbooting technique is applied for the OBUs with prior knowledge to accelerate the learning speed. Simulation results show that the proposed action selection strategy can efficiently increase the packet delivery ratio, the reputation and the utility of the each OBU.

Bioerosional innovation for living in carbonate hardgrounds in the Early Ordovician of Sweden (2001)

Some of the world's oldest macroborings occur in hardgrounds in lower Ordovician (Arenig) limestones exposed on the island of Öland, southern Sweden. The trace fossils, which are described here as Gastrochaenolites oelandicus isp. nov., appear to be dwelling structures excavated in the indurated substrate by invertebrates of unknown taxonomic affinity. They are the oldest examples of this ichnogenus. The appearance of a macroboring life habit at this early time represents a revolutionary new adaptive strategy for inhabiting carbonate hardgrounds. However, this innovative strategy apparently was not successful for the long term, because this particular macroboring taxon seems to have disappeared shortly after its early Ordovician appearance.
A thermodynamically consistent model of bone rotary remodeling: a 2D study (Conference Abstract) (2017)

Bone remodeling characterizes the lifelong turnover and adaptation of bone tissue to its mechanical and biochemical environment. This phenomenon is of major importance, as it governs healing as well as osseointegration around implants (Haïat et al. 2014). Several scales and physics are involved in bone remodeling. Indeed, changes of the mechanical environment of bone at the organ scale lead to apposition and resorption of bone material at the microstructural scale which, in turn, result in an evolution of the mechanical properties of bone tissue, at the tissue scale. Moreover, biochemical stimuli can also trigger bone remodeling. In this work, we present a thermodynamically consistent framework for describing the evolution of bone elastic properties at the tissue scale. Such an approach allows to consider not only mechanics, but also phenomena related to biological activity. In particular, we focus on the stress driven rotation of the principal axes of the elastic tensor of bone. Rotation of bone material axes describes, at the tissue scale, the reorientation of bone microstructure induced by the macroscopic loading.
Third- and fourth-order active dispersion compensation using a phase modulator in a terabit/s OTDM transmission (2001)

The third- and fourth-order dispersions of a transmission line were simultaneously compensated for by using a phase modulator. The pulse broadening of a 380 fs pulse after a 70 km transmission in a 1.28 Tbit/s OTDM experiment was as small as 20 fs.
Can susceptibility to carcinoid tumors be inherited? (1989)

Previously, all carcinoid tumors were considered to occur sporadically. We present an extremely rare series of three first-degree relatives in two generations with proximal duodenal carcinoid tumors and other family-associated neoplasms. This unusual circumstance, which has never been described previously, represents the sixth case of familial clustering of carcinoid tumors reported in the world's literature.
Effect of a High Protein Diet on Calcium Metabolism in Sheep (1991)

高タンパク質飼料を摂取しためん羊の腎におけるカルシウム(Ca)の動態およびEDTA負荷時の血中へのCa動員量を検討した.対照飼料(CP:9.9%, ME:2.02Mcal/kg)と高タンパク質飼料(CP:19.6%, ME:2.02Mcal/kg)を6頭の成めん羊に給与し,腎クリアランス試験とEDTA負荷試験を行なった.高タンパク質飼料摂取により,尿中Ca排泄量の増加と血漿Ca濃度の減少が見られた.その要因として,糸球体濾過量の増加とそれに伴う糸球体濾過Ca量の増加が,尿中Ca排泄量の増加をもたらしたと考えられた.また,血漿遊離ハイドロキシプロリン濃度は,高タンパク質飼料区で高くなった.EDTA負荷により,血漿イオン化Ca濃度は全動物において直線的に減少したが,低下の程度は高タンパク質飼料の摂取により緩和される傾向が認められ,Ca動員量は高タンパク質飼料区で有意に増加した.EDTA負荷前の血漿上皮小体ホルモン(iPTH)濃度は,高タンパク質飼料区で高かったが,負荷時および負荷後の血漿iPTH濃度の増加は,高タンパク質飼料摂取により小さくなる傾向であった.めん羊に高タンパク質飼料を給与すると,尿中Ca排泄量の増加と血漿Ca濃度の減少がみられるが,骨吸収は促進されており,これはPTH分泌とその反応性の増加によるものと考えられた.
Desymmetrization of Cyclohexadienylsilanes. Regio-, Diastereo-, and Enantioselective Access to Sugar Mimics (1999)

Desymmetrization of cyclohexadienylsilanes available from Birch reduction of the corresponding arylsilanes is efficiently carried out using Sharpless asymmetric dihydroxylation and aminohydroxylation. Complete diastereocontrol and reasonable enantiocontrol have been attained during the preparation of the desired diols. An excellent regiocontrol has also been observed during aminohydroxylation of dienylsilanol 6b. The resulting diol 8 and hydroxycarbamate 27 have then been elaborated further, offering a straightforward access to various types of cyclitols, aminocyclitols, carbasugars, as well as the antibiotic palitantine 4. The complete functionalization of the original arylsilanes 5 is thus typically achieved in fewer than eight steps with high stereoselectivities and excellent overall yield.
Functional analysis of CD82 in the early phase of T cell activation: roles in cell adhesion and signal transduction (1998)

To define T cell co-stimulatory molecules that work in the early phase of T cell activation, we established monoclonal antibodies (mAb) that inhibit or enhance T cell activation by the histiocytic leukemia cell line U937. One of the mAb, 53H5, which recognized both T cells and U937, was identified to bind to CD82 by expression cloning. Functional analyses of CD82 revealed that 1) CD82 needs to exist on both T cells and U937 for the full activation of T cells; 2) CD82 expression is up-regulated on both T cells and U937 by stimulation such as CD3 ligation or treatment with phorbol 12-myristate 13-acetate; 3) overexpression of CD82 enhances both homotypic and heterotypic cell adhesion between T cells and U937; 4) CD82 signal co-stimulates T cells and the signal works synergistically with the CD28-mediated T cell co-stimulation signal; 5) in mixed leukocyte reactions using U937 as stimulator cells, CD82 overexpression on U937 correlates with the higher allogeneicity of U937 cells. These results indicate that CD82 co-stimulates T cells not only by sending intra-T cell signals that work synergistically with CD28 signals but also by inducing enhanced T cell-antigen-presenting cell interaction.
Synthesis of the Tetracyclic Bis(acetal) Lactone Portion of Saudin (2003)

Abstract Two synthetic approaches towards the synthesis of the tetracyclic lactone 4 , containing the caged bis(acetalic) backbone of Saudin, were explored. Both sequences included the utilization of the known epoxy‐acetal 3 , prepared stereoselectively by means of an intramolecular radical cyclization, as the common key intermediate, allowing total control over the relative stereochemistry of four consecutive chiral centers. Oxidative degradation with ruthenium dioxide and unsymmetrical ozonolysis reactions provided the new two key synthons in each synthetic route. (© Wiley‐VCH Verlag GmbH &amp; Co.

Toward a Rapid Production of Multivirus-Specific T Cells Targeting BKV, Adenovirus, CMV, and EBV from Umbilical Cord Blood (2017)

Umbilical cord blood (CB) has emerged as an effective alternative donor source for hematopoietic stem cell transplantation. Despite this success, the prolonged duration of immune suppression following CB transplantation and the naiveté of CB T cells leave patients susceptible to viral infections. Adoptive transfer of ex vivo-expanded virus-specific T cells from CB is both feasible and safe. However, the manufacturing process of these cells is complicated, lengthy, and labor-intensive. We have now developed a simplified method to manufacture a single culture of polyclonal multivirus-specific cytotoxic T cells in less than 30 days. It eliminates the need for a live virus or transduction with a viral vector, thus making this approach widely available and GMP-applicable to target multiple viruses. The use of overlapping PepMixes as a source of antigen stimulation enable expansion of the repertoire of the T cell product to any virus of interest and make it available as a third party "off the shelf" treatment for viral infections following transplantation.
Vascular Reconstruction for Limb Salvage in Sarcoma of the Lower Extremity (1996)

Limb-preserving resection of sarcoma of the lower extremity can be performed with satisfactory function of the limb maintained, even if it becomes necessary to resect the femoral vessels. Autologous venous graft for vascular reconstruction is the treatment of choice. In spite of the high incidence of metastases, considerable long-term survival is possible.

Antioxidants Derived from Vitamin E: An Overview (2007)

Alpha-tocopherol is a very well-known potent antioxidant and radical scavenger in chemical and biological systems. Its structure has served as starting point for design and synthesis of more potent antioxidant analogues with regard to its potential clinical and nutritional applications in human health. Furthermore, in recent years, intense research has been made not only in the development of hybrid compounds with classical drug moieties in a single molecule, but also in the preparation of label analogues with application in tocopherol metabolism studies. In the present review principal progresses in these aspects are outlined.
Insertion Copolymerization of Difunctional Polar Vinyl Monomers with Ethylene (2015)

A single-step synthesis, structural characterization and application of a neutral, acetonitrile ligated, palladium-phosphinesulfonate complex [{P<sup>∧</sup>O}PdMe(L)] (P<sup>∧</sup>O = κ<sup>2</sup>-P,O-Ar<sub>2</sub><i>P</i>C<sub>6</sub>H<sub>4</sub>SO<sub>2</sub><i>O</i> with Ar = 2-MeOC<sub>6</sub>H<sub>4</sub>; L = CH<sub>3</sub>CN) (<b>3</b>) in coordination/insertion copolymerization of ethylene with difunctional olefin is investigated. In a significant development, complex <b>3</b> was found to catalyze insertion copolymerization of industrially relevant 1,1-disubstituted difunctional vinyl monomers for the first time. Thus, insertion copolymerization of ethyl-2-cyanoacrylate (ECA or super glue) and trifluoromethyl acrylic acid (TFMAA) with ethylene produced the corresponding copolymers with 6.5% ECA and 3% TFMAA incorporation. Increasing the concentration of difunctional olefins led to higher incorporation but at the expense of lower activities. These observations indicate that complex <b>3</b> tolerates difunctional vinyl monomers and provides direct access to difunctional polyolefins that have not been attempted before.
Potential role of proliferation signal inhibitors on atherosclerosis in renal transplant patients (2006)

Over the last decade, there has been a decrease in acute graft rejection rates following renal transplantation; however, this has not corresponded with an improvement in long-term outcomes of transplantation. One of the major causes of long-term morbidity and mortality in renal transplant recipients is cardiovascular disease. Immunosuppressive regimens, especially those including steroids and calcineurin inhibitors, have a negative role in the induction of cardiovascular risk factors. The proliferation signal inhibitors (PSIs)/mammalian target of rapamycin (mTOR) inhibitors sirolimus and everolimus have shown considerable promise in reducing acute rejection in renal transplant recipients. Although PSIs are associated with an increase in hyperlipidaemia (hypercholesterolaemia and hypertriglyceridaemia), which is a major risk factor for atherosclerosis and associated cardiovascular disease, recent studies with sirolimus have demonstrated protection from atheroma progression in hyperlipidaemic apolipoprotein E-deficient mice. Here, we summarize the results of pre-clinical and clinical studies with sirolimus and everolimus, with particular emphasis on the beneficial and adverse effects that these drugs exert on the cardiovascular system, and the underlying molecular mechanisms.
A Phononic Crystal with Differently Configured Double Defects for Broadband Elastic Wave Energy Localization and Harvesting (2021)

Several previous studies have been dedicated to incorporating double defect modes of a phononic crystal (PnC) into piezoelectric energy harvesting (PEH) systems to broaden the bandwidth. However, these prior studies are limited to examining an identical configuration of the double defects. Therefore, this paper aims to propose a new design concept for PnCs that examines differently configured double defects for broadband elastic wave energy localization and harvesting. For example, a square-pillar-type unit cell is considered and a defect is considered to be a structure where one piezoelectric patch is bonded to a host square lattice in the absence of a pillar. When the double defects introduced in a PnC are sufficiently distant from each other to implement decoupling behaviors, each defect oscillates like a single independent defect. Here, by differentiating the geometric dimensions of two piezoelectric patches, the defects’ dissimilar equivalent inertia and stiffness contribute to individually manipulating defect bands that correspond to each defect. Hence, with adequately designed piezoelectric patches that consider both the piezoelectric effects on shift patterns of defect bands and the characteristics for the output electric power obtained from a single-defect case, we can successfully localize and harvest the elastic wave energy transferred in broadband frequencies.
Vinyl cation formation by decomposition of vinyl-lead triacetates. The reactions of vinylmercury and vinyltin compounds with lead tetra-acetate (1990)

Vinylmercury compounds and vinylstannanes undergo rapid metal–metal exchange with lead tetra-acetate in chloroform to generate vinyl-lead triacetates, unstable compounds which undergo a thermodynamically favourable reductive elimination of lead(II) acetate. In the presence of mercury(II) salts, vinyl-lead triacetates collapse to the corresponding enol acetate, but in the absence of mercury(II) they yield either the enol acetate or an acetylene depending on the substitution at the double bond. Evidence for the formation of vinyl cations in the collapse of a number of vinyl-lead triacetates has been obtained. Strong support for such intermediates comes from the decomposition of (E)-o-methoxystyryl-lead triacetate, where the nature of the participation by the neighbouring methoxy group excluded the possibility of involvement of an alkylidenecarbene. Attempted trapping of an alkylidenecarbene by cyclohexane in the decomposition of 2-methylprop-1-enyl-lead triacetate was also unsuccessful, indicating the absence of such an intermediate.
A review and analysis of supply chain operations reference (SCOR) model (2004)

Research on supply chain management can be broadly classified into three categories, namely, operational, design, and strategic. While many analytical and numerical models have been proposed to handle operational and design issues, formal models for strategic planning are scarce. The supply chain operations reference (SCOR) model, developed by the Supply Chain Council, is a strategic planning tool that allows senior managers to simplify the complexity of supply chain management. It is firmly rooted in industrial practices and is poised to become an industrial standard that enables next‐generation supply chain management. This paper gives a brief introduction to the SCOR model, analyzes its strength and weakness, and discusses how it can be used to assist managers for strategic decision making.
