Influence of Crystallization Conditions on the Microstructure and Electromechanical Properties of Poly(vinylidene fluoride−trifluoroethylene−chlorofluoroethylene) Terpolymers (2003)

The crystallization process and its influence on the microstructures and in turn the ferroelectric and electromechanical properties of poly(vinylidene fluoride−trifluoroethylene−chlorofluoroethylene) (P(VDF−TrFE−CFE)) terpolymer were investigated. It was found that, in addition to the crystallites formed at the isothermal crystallization temperature Tx, further crystallites form during the rapid cooling from Tx to room temperature. The proportion of lower melting crystallites increases with Tx, and for Tx = 142 °C, this proportion is more than 90%. The experimental results show that the lower melting crystallites have a higher fraction of the all-trans conformation (and thus more polar-phase component) than the crystallites formed at Tx. As a result, the higher Tx samples show an increased polarization hysteresis and reduced electric field induced strain response. For example, the strain is reduced from −5.9 to −4.2% as Tx is increased from 112 to 142 °C. In addition, the experimental results in combination with other reported results indicate that CFE units are included in the crystalline lattice. Consequently, the influence of CFE on the ferroelectric behavior of the polymer is through the defects induced in the crystal lattice.
Next-generation nanocrystals for cellular imaging: non-blinking, non-bleaching phosphors (2013)

Nanocrystals that have unusual or exceptional optical properties have shown promise as transformative probes for biological imaging. Phosphorescent upconverting nanoparticles (UCNPs) have proven to be especially promising as biological labels, and single-particle studies of UCNPs have shown that they exhibit nearly ideal properties as single molecule imaging probes. UCNPs absorb two or more photons in the near infrared and emit one at shorter wavelengths in the visible or nIR, an unusual characteristic that distinguishes them from all luminescent chemicals in the cell, and one that suggests background-free cellular imaging. We have shown that UCNPs do not blink on and off as most other probes do, and that they posses remarkable photostability, resisting photobleaching under continuous irradiation long after organic dyes, proteins, and even quantum dots are extinguished. We have recently developed synthetic methods for control of UCNP size, and completed a combinatorial lanthanide scan in order to tune emission wavelengths for multicolor upconverted imaging. We have also developed methods for studying single nanocrystal lifetimes and emission spectra, which has allowed us to understand lanthanide-lanthanide communication within the nanocrystal.
A case of adult Still's disease occurred during pregnancy. (1991)

妊娠18週で発症した成人Still病と考えられた1例を経験した.症例は30歳の女性で, 19歳に原因不明の発熱を生じ,成人Still病の発症が疑われた.妊娠18週のときより発熱,多関節痛が出現した.入院時の現症では,リンパ節腫大,肝脾腫,多関節の腫脹,可動痛を認めた.発熱時に両下腿に融合傾向の強い斑状紅斑がみられた.検査成績では,血沈亢進,好中球増加,軽度の肝機能障害, CRP強陽性,フェリチン高値などを認めた.他の発熱疾患を否定することにより成人Still病が疑われた.入院後aspirinを使用したが肝機能障害が増悪したため, naproxenに変更して肝機能障害なく軽快した.胎児に一時子宮内発達遅延を認めたが, 38週に男子を出産し母子共に異常なかった.分娩後現在まで再発はみられていない.妊娠中に発症した成人Still病は自験例を含めて6例しか報告されておらず,これらについて文献的考察を行った.
Zusammenhang zwischen Glukosehomöostase und Immunantwort bei Neugeborenen (2010)

Einführung: Die akute Hyperglykämie tritt gehäuft im Rahmen schwerer systemischer Infektionen bei Neugeborenen auf. Der Zusammenhang zwischen Hyperglykämie und Inflammation ist nicht abschließend geklärt. Die Hyperglykämie trägt vermutlich zum Unterhalt und der Verstärkung einer systemischen Inflammation bei und gilt bei erwachsenen Patienten auf Intensivstationen als negativer prognostischer Faktor. Neugeborene sind anfällig für Infektionen und eine systemische Inflammation (SIRS) ausgelöst durch proinflammatorische Zytokine. Diese Arbeit soll den Zusammenhang zwischen neonataler Glukosehomöostase und der Produktion pro-inflammatorischer Zytokine darstellen. Methoden: Innerhalb eines in-vitro Sepsis-Modells wurde das Nabelschnurblut von Reifgeborenen (n=10), von Frühgeborenen &gt;32 vollendeten Schwangerschaftswochen (SSW) (n=16) und von Frühgeborenen &lt;32 SSW (n=18) mit verschiedenen Glukose- (0–1000mg/dl) und Insulinkonzentrationen (0–10 IE/l) versetzt. Nach Inkubation mit Lipopolysaccharid (LPS) (0,3ng/ml) wurde intrazytoplasmatisch der Anteil der zytokinproduzierenden CD 14+ Zellen gemessen.
Structures of an ATM switching system with MPLS functionality (2003)

MultiProtocol Label Switching (MPLS) is a new IP over ATM technology that can be deployed in private networks as well as in public backbone networks operated by Internet service providers or telecommunication operators. From the viewpoint of telecommunication, we propose several structures of an ATM switching system having MPLS functionality that swaps a label at the packet forwarding engine and controls a label switched path at the MPLS controller. The proposed structures are discussed, and compared with each other according to their features. We also introduce the new ATM switching system named HANbit ACE 64 system that supports the MPLS functionality.
Proposal and Simulation of a Low Loss, Highly Efficient Monolithic III-V/Si Optical Phase Shifter (2019)

Carrier-depletion monolithic III-V/Si optical phase modulators are proposed and numerically investigated. Thanks to the larger carrier-induced refractive index change of the III-Vs compared to Si, the III-V/Si phase modulator is predicted to achieve 0.07-Vcm modulation efficiency at 16-dB/cm optical loss at 1310-nm wavelengths.
BLAST: THE REDSHIFT SURVEY (2009)

The Balloon-borne Large Aperture Submillimeter Telescope (BLAST) has recently surveyed 8.7 deg 2 centered on Great Observatories Origins Deep Survey-South at 250, 350, and 500 m. In Dye et al., we presented the catalog of sources detected at 5 in at least one band in this field and the probable counterparts to these sources in other wavebands. In this paper, we present the results of a redshift survey in which we succeeded in measuring redshifts for 82 of these counterparts. The spectra show that the BLAST counterparts are mostly star-forming galaxies but not extreme ones when compared to those found in the Sloan Digital Sky Survey. Roughly one quarter of the BLAST counterparts contain an active nucleus. We have used the spectroscopic redshifts to carry out a test of the ability of photometric redshift methods to estimate the redshifts of dusty galaxies, showing that the standard methods work well even when a galaxy contains a large amount of dust. We have also investigated the cases where there are two possible counterparts to the BLAST source, finding that in at least half of these there is evidence that the two galaxies are physically associated, either because they are interacting or because they are in the same large-scale structure. Finally, we have made the first direct measurements of the luminosity function in the three BLAST bands. We find strong evolution out to z = 1, in the sense that there is a large increase in the space density of the most luminous galaxies. We have also investigated the evolution of the dust-mass function, finding similar strong evolution in the space density of the galaxies with the largest dust masses, showing that the luminosity evolution seen in many wavebands is associated with an increase in the reservoir of interstellar matter in galaxies.
Formulation of the Theoretical Model of Coronary Circulation Based on Mixture Theory (2008)

The disorder of the coronary circulation system, which supplies blood for the working heart, may cause ischemic heart disease such as myocardial infarction, angina pectoris. On the other hand, the interaction between intramyocardial pressure and coronary blood flow is recognized to be an important factor that influences the hemodynamics of coronary circulation. In this work, a multiphasic model for coronary circulation system is proposed based on mixture theory by treating the myocardial matrix and the blood in hierarchical coronary system as solid phase and multi-fluid phase respectively. The governing equations and constitutive relations have been derived by applying conservation laws and entropy inequality in the framework of mixture theory. The microscopic properties, such as the viscosity of blood or the compliance of the micro vessel are represented by their macroscopic counterparts. The abilities of representing the characteristic behavior of coronary system have been confirmed by numerical examples.

Development of bone regeneration strategies using human periosteum‐derived osteoblasts and oxygen‐releasing microparticles in mandibular osteomyelitis model of miniature pig (2019)

Hypoxia and limited vascularization inhibit bone growth and recovery after surgical debridement to treat osteomyelitis. Similarly, despite significant efforts to create functional tissue-engineered organs, clinical success is often hindered by insufficient oxygen diffusion and poor vascularization. To overcome these shortcomings, we previously used the oxygen carrier perfluorooctane (PFO) to develop PFO emulsion-loaded hollow microparticles (PFO-HPs). PFO-HPs act as a local oxygen source that increase cell viability and maintains the osteogenic differentiation potency of human periosteum-derived cells (hPDCs) under hypoxic conditions. In the present study, we used a miniature pig model of mandibular osteomyelitis to investigate bone regeneration using hPDCs seeded on PFO-HPs (hPDCs/PFO-HP) or hPDCs seeded on phosphate-buffered saline (PBS)-HPs (hPDCs/PBS-HP). Osteomyelitis is characterized by a series of microbial invasion, vascular disruption, bony necrosis, and sequestrum formation due to impaired host defense response. Sequential plain radiography, computed tomography (CT), and 3D reconstructed CT images revealed new bone formation was more advanced in defects that had been implanted with the hPDCs/PFO-HPs than in defects implanted with the hPDCs/PBS-HP. Thus, PFO-HPs are a promising tissue engineering approach to repair challenging bone defects and regenerate structurally organized bone tissue with 3D architecture.
Novel peptides suppress VEGFR-3 activity and antagonize VEGFR-3-mediated oncogenic effects (2014)

Vascular endothelial growth factor receptor 3 (VEGFR-3) supports tumor lymphangiogenesis. It was originally identified as a lymphangiogenic factor expressed in lymphatic endothelial cells. VEGFR-3 was detected in advanced human malignancies and correlated with poor prognosis. Our previous studies show that activation of the VEGF-C/VEGFR-3 axis promotes cancer metastasis and is associated with clinical progression in patients with lung cancer, indicating that VEGFR-3 is a potential target for cancer therapy. In this study, we developed eight peptides targeting VEGFR-3. Two peptides strongly inhibited the kinase activity of VEGFR-3 and suppressed VEGF-C-mediated invasion of cancer cells. Moreover, these peptides abolished VEGF-C-induced drug resistance and tumor initiating cell formation. This study demonstrates the therapeutic potential of VEGFR-3-targeting peptides.
Synthesis of Phospholane–Phosphoramidite Ligands and their Application in Asymmetric Catalysis (2015)

Abstract A set of phospholane–phosphoramidite ligands, which possess four elements of chirality, has been synthesized through a modular diastereoselective process. The ligands were applied in the Rh‐catalyzed asymmetric CC hydrogenation of several functionalized olefins with enantioselectivities of up to 99 % ee and a turnover frequency of up to 12 000 h −1 , in the Rh‐catalyzed hydroformylation of vinyl arenes with enantioselectivities of up to 79 % ee , and in the Ir‐catalyzed asymmetric CN hydrogenation of different aryl imines with enantioselectivities of up to 79 % ee .
MP51-14 PERCUTANEOUS NEPHROLITHOTOMY AFTER RECENT UROLITHIASIS RELATED SEPSIS: WHAT SHOULD PATIENTS EXPECT? ANSWERS FROM A MATCHED PAIR ANALYSIS (2016)

those with prior URS in the 6 month preceding the study URS (3.79% v 2.59%), and those with ureteral stent placement within 30 days of URS (3.56% v 2.82%). All associations were statistically significant on logistic regression analysis (p < 0.001). Risk factors for ureteral stricture were similar in patients receiving SWL, with the exception of stone location, which had no association with stricture risk.
Micronutriments non essentiels et pourtant… (2017)

Les aliments d’origine végétale contiennent de nombreux composés dotés d’activités biologiques diverses, antioxydantes, anti-inflammatoires, antimicrobiennes… Ce sont des micronutriments dits « non essentiels » de notre alimentation, en raison de l’absence de pathologies associées à des carences. Ils ne bénéficient d’ailleurs pas d’apports nutritionnels conseillés. De nombreuses études, épidémiologiques, cliniques et expérimentales chez l’animal ou sur des modèles cellulaires, établissent qu’ils pourraient contribuer significativement à préserver notre santé.
Small Serotonin-Producing Neuroendocrine Tumor of the Pancreas Associated With Pancreatic Duct Obstruction (2011)

Serotonin produced by pancreatic neuroendocrine tumors can induce fibrosis and pancreatic duct obstruction. Pancreatic neuroendocrine tumors should be considered when CT shows a small hypervascular mass associated with upstream pancreatic duct dilatation or atrophy. Evidence of small pancreatic neuroendocrine tumors should be sought in cases of idiopathic pancreatic duct stenosis.
Stabilizing Mechanism in Bone-Grafting of a Large Glenoid Defect (2010)

An osseous defect with a width that is > or =19% of the glenoid length remains unstable even after Bankart lesion repair. The stabilizing mechanism of bone-grafting was the restoration of the glenoid concavity.
Investigation of high-temperature degradation of platinum thin films with an in situ resistance measurement apparatus (1998)

Many microfabricated systems require metallizations that can withstand high temperatures. In particular, a microfabricated chemical reactor system which we are investigating needs thin metal films for heating and temperature sensing that can withstand prolonged 1000/spl deg/C exposure. The current microreactor metallization, a 100-nm platinum film with a 10-nm titanium adhesion layer, degrades at temperatures greater than 700/spl deg/C. This degradation was examined with a custom-built high-temperature resistance measurement apparatus in addition to chemical analysis, scanning electron microscopy (SEM), atomic-force microscopy (AFM) and wafer curvature measurements. Thicker films and coating layers increased the lifetime of these films while exposure to oxygen decreased lifetime, consistent with the hypothesized degradation mechanism of agglomeration.
Titanium‐Mediated Oxidative Arylation of Homoallylic Alcohols (2011)

E-substituierte Styrole wurden durch TiIV-vermittelte oxidative Kupplung aus terminalen Olefinen und Grignard-Reagentien synthetisiert (siehe Schema). Das Substratspektrum umfasst Homoallylalkohole mit verschiedensten funktionellen Gruppen sowie substituierte Aryl-Grignard-Reagentien. Die Reaktion verläuft vermutlich über eine Aryltitanierung mit anschließender β-Hydrid-Eliminierung; das Aren wird dann aus einem TiIVH(Aryl)-Intermediat eliminiert.
Chemoenzymatic Synthesis of Globo‐series Glycosphingolipids and Evaluation of Their Immunosuppressive Activities (2022)

Glycosphingolipids (GSLs) play essential roles in many important biological processes, making them attractive synthetic targets. In this paper, a viable chemoenzymatic method is described for the synthesis of globo-series GSLs, namely, Gb4, Gb5, SSEA-4, and Globo H. The strategy uses a chemically synthesized lactoside acceptor equipped with a partial ceramide structure that is uniquely extended by glycosyltransferases in a highly efficient one-pot multiple enzyme (OPME) procedure. A direct and quantitative conversion of Gb4 sphingosine to Globo H sphingosine is achieved by performing two-sequential OPME glycosylations. A reduction and N-acylation protocol allows facile incorporation of various fatty acids into the lipid portions of the GSLs. The chemically well-defined lipid-modified Globo H-GSLs displayed some differences in their immunosuppressive activities, which may benefit the structural modifications of Globo H ceramides in finding new types of immunosuppressive agents. The strategy outlined in this work should be applicable to the rapid access to other complex GSLs.

Massive Tears of the Rotator Cuff (2010)

Repair of massive rotator cuff tears is technically difficult but often feasible. Technical and biological challenges to a successful repair include inelastic poor-quality tendon tissue, scarring, muscle atrophy, and fatty infiltration. Fatty infiltration of the involved rotator cuff muscles has been identified as an important negative prognostic factor for the outcome after repair of massive rotator cuff tears. Tendon transfer is a good option for young patients and manual laborers with an irreparable massive rotator cuff tear. Arthroplasty can be considered for the treatment of symptomatic massive rotator cuff tears in patients who have glenohumeral arthritis.

Comparison of simulcast and scalable video coding in terms of the required capacity in an IPTV network (2007)

The diversity of multimedia-enabled devices supporting streamed multimedia is ever growing. Multicast delivery of TV channels in IP networks to a heterogeneous set of clients can be organised in many different ways, which brings up the discussion which one is optimal. Scalable video streaming has been believed to be more efficient in terms of network capacity utilisation than simulcast video delivery because one flow can serve all terminals, while with simulcast all resolutions are offered in parallel. At the same time, it is also largely recognised that in order to provide the same video quality compared to non-layered video coding, scalable video coding (SVC) incurs a bit rate penalty. In this paper we compare simulcast and SVC in terms of their required capacity in an IPTV network scenario where a bouquet of TV channels is offered to the subscribers. We develop methods to calculate and approximate the capacity demand for two different subscriber behaviour models. These methods are then used to explore the influence of various parameters: the SVC bit rate penalty, the number of offered channels, the channel popularity and the number of subscribers. The main contribution of this paper is that we derive an analytical formula to calculate the SVC limit bit rate penalty beyond which SVC is less efficient than simulcast. In the realistic IPTV examples considered here, the limit is found to lie between 16% and 20%, while the reported values for this coding penalty range from 10% up to 30% for current H.264 SVC codecs, indicating that SVC in IPTV is not always more efficient than simulcast.
Simplified Successive-Cancellation List decoding of polar codes (2016)

The Successive-Cancellation List (SCL) decoding algorithm is one of the most promising approaches towards practical polar code decoding. It is able to provide a good trade-off between error-correction performance and complexity, tunable through the size of the list. In this paper, we show that in the conventional formulation of SCL, there are redundant calculations which do not need to be performed in the course of the algorithm. We simplify SCL by removing these redundant calculations and prove that the proposed simplified SCL and the conventional SCL algorithms are equivalent. The simplified SCL algorithm is valid for any code and can reduce the time-complexity of SCL without affecting the space complexity.
Data on immunogenicity and reactogenicity to COVID-19 vaccination among patients receiving maintenance dialysis (2022)

Compared with the general population, patients receiving maintenance dialysis are at increased risk for morbidity and mortality associated with coronavirus disease 2019 (COVID-19). Currently, data on severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2)-specific immunity post-vaccination in patients on maintenance dialysis are scarce given that the effectiveness of the vaccines has not been explicitly tested in this population due to their common exclusion from SARS-CoV-2 vaccination trials. We herein present data of the specific cellular (interferon-γ and interleukin-2 ELISpot assays) and humoral immune responses (dot plot array and chemiluminescent microparticle immunoassay) at 4 weeks and 6 weeks following a single dose or a complete homologous dual dose SARS-CoV-2 vaccine regimen in 60 adult patients on maintenance dialysis (six with a history of COVID-19). The data was produced in a framework of a project focused on a) quantifying the immune response after full vaccination, b) evaluating the short-term durability of immune response, and c) examining the reactogenicity of SARS-CoV-2 vaccine regimens in patients on maintenance dialysis.
Warm Starting Bandits with Side Information from Confounded Data (2020)

We study a variant of the multi-armed bandit problem where side information in the form of bounds on the mean of each arm is provided. We describe how these bounds on the means can be used efficiently for warm starting bandits. Specifically, we propose the novel UCB-SI algorithm, and illustrate improvements in cumulative regret over the standard UCB algorithm, both theoretically and empirically, in the presence of non-trivial side information. As noted in (Zhang & Bareinboim, 2017), such information arises, for instance, when we have prior logged data on the arms, but this data has been collected under a policy whose choice of arms is based on latent variables to which access is no longer available. We further provide a novel approach for obtaining such bounds from prior partially confounded data under some mild assumptions. We validate our findings through semi-synthetic experiments on data derived from real datasets.
