A <italic>Ka</italic>-Band Transformer-Based Doherty Power Amplifier for Multi-Gb/s Application in 90-nm CMOS (2018)

A Ka-band transformer (TF)-based Doherty power amplifier (DPA) is designed and fabricated in 90-nm CMOS process. Symmetrical Doherty structure is used to improve the 6-dB power backoff efficiency. The high turn ratio (N = 2) current-type TF is adopted for the load modulation in a DPA to avoid from leakage power. The measured small signal gain is 19.8 dB with 3-dB bandwidth from 28.7 to 41.9 GHz. The proposed PA achieves 20.7-dBm saturated output power with above 32% power added efficiency (PAE) at 34 GHz. In the 6-dB power backoff region, the PAE of the proposed PA is about 1.7× of that in a class-A PA.
The influence of endothelial cells on the ECM composition of 3D engineered cardiovascular constructs (2008)

Tissue engineering of small diameter (<5 mm) blood vessels is a promising approach to develop viable alternatives for autologous vascular grafts. Development of a functional, adherent, shear resisting endothelial cell (EC) layer is one of the major issues limiting the successful application of these tissue engineered grafts. The goal of the present study was to create a confluent EC layer on a rectangular 3D cardiovascular construct using human venous cells and to determine the influence of this layer on the extracellular matrix composition and mechanical properties of the constructs. Rectangular cardiovascular constructs were created by seeding myofibroblasts (MFs) on poly(glycolic acid) poly-4-hydroxybutyrate scaffolds using fibrin gel. After 3 or 4 weeks, ECs were seeded and co-cultured using EGM-2 medium for 2 or 1 week, respectively. A confluent EC layer could be created and maintained for up to 2 weeks. The EGM-2 medium lowered the collagen production by MFs, resulting in weaker constructs, especially in the 2 week cultured constructs. Co-culturing with ECs slightly reduced the collagen content, but had no additional affect on the mechanical performance. A confluent endothelial layer was created on 3D human cardiovascular constructs. The layer was co-cultured for 1 and 2 weeks. Although, the collagen production of the MFs was slightly lowered, co-culturing ECs for 1 week results in constructs with good mechanical properties and a confluent EC layer.
New Phenylethanoid Glycosides from the Fruits of Forsythia Suspense (Thunb.) Vahl (2009)

Forsythosides H-J (1-3), three new caffeoyl phenylethanoid glycosides (CPGs), were isolated from the fruits of Forsythia suspense (Thunb.) Vahl., together with six known phenylethanoid glycosides: Forsythoside A (4), Forsythoside F (5), Forsythoside E (6), 2-(3,4-dihydroxyphenyl)ethyl-beta-D-glucopyranoside (7), phenethyl alcohol beta-D-xylo-pyranosyl-(1-->6)-beta-D-glucopyranoside (8) and calceolarioside B (9). Their structures were determined by spectroscopic and chemical methods.
Prevention of oesophageal injury during catheter ablation of atrial fibrillation: is monitoring of oesophageal temperature the solution? (2010)

This editorial refers to ‘Oesophageal temperature monitoring and incidence of oesophageal lesions after pulmonary vein isolation using a remote robotic navigation system’ by A. Rillig et al. , Europace 2010;12:655–61. 

Atrio-oesophageal fistula is among the most dangerous complications of interventional treatment of atrial fibrillation. The complication was first observed during intraoperative radiofrequency ablation of atrial fibrillation1 but subsequently also reported after catheter based radiofrequency ablation of atrial fibrillation.2 Atrio-oesophageal fistula is associated with high mortality3 even if the correct diagnosis is made relatively early. However, the diagnosis of the complication often is delayed because of the significant time delay of its occurrence after the ablation procedure (which mostly is 1–4 weeks) and unspecific initial symptoms.3,4 The mechanism most likely leading to atrio-oesophageal fistula after radiofrequency ablation of atrial fibrillation is the induction of thermal oesophageal injury during the ablation procedure; this pathophysiologic pathway could recently be observed in a patient who declined intervention after diagnosis of atrio-oesophageal fistula.4 The incidence of oesophageal injury after radiofrequency ablation of atrial fibrillation has been described between 5% and almost 50%5–7 depending on the radiofrequency power settings and ablation strategies. After the initial injury of the oesophagus, inflammation, and tissue necrosis promoted by the biological milieu in the oesophagus seem to pave the way for the occurrence of atrio-esophagel fistula. However, it is unclear which factors determine the progression of the frequently observed oesophageal lesion to the relatively rare but …
Comparisons of Inter-Domain Routing Schemes for Heterogeneous Ad Hoc Networks (2005)

We propose three inter-domain routing schemes for ad hoc networks, namely the implicit foreign degree based protocol (IFD), the explicit locally optimal protocol (ELO) and the explicit limited scope protocol (ELS). We studied the performance of these different schemes. Our simulation studies reveal that the explicit schemes can achieve high packet delivery ratio and good average end-to-end delay at a lower overhead cost compared to IFD. We also compared our approaches with LANMAR, an existing scalable routing protocol for ad hoc networks. The results show that our approach outperforms LANMAR in terms of the packet delivery ratio and control overhead, while maintaining comparable end-to-end delay at low and medium mobility rate (less than 8 m/s).
Stimulated Raman scattering of a high-Q liquid-hydrogen droplet in the ultraviolet region (2002)

We show that a liquid-hydrogen droplet can achieve high- Q values that exceed 10(9) for whispering-gallery modes in the ultraviolet. We show also that pumping high- Q liquid-hydrogen droplets with ultraviolet laser radiation generates many vibrational and rotational Raman sidebands that cover a broad spectral range from the ultraviolet to the near infrared.
Activity and subcellular distribution of cathepsins in primary human monocytes (2003)

Cathepsins (Cat) in antigen presenting cells (APC) control antigen processing as well as major histocompatibility complex class II transport and function. The set of active Cat and the subcellular architecture of the class II antigen presentation compartment are largely unknown in primary human APC, including peripheral blood monocytes. We used novel chemical tools to visualize Cat in an activity-dependent manner. Primary human monocytes contained active CatS, -B, and -H, while CatL was absent. Expression and activity patterns of Cat in human myelo-monocytoid cell lines were distinct from those found in primary cells. On a subcellular scale, the bulk of active Cat was concentrated in lysosomes in primary monocytes. In late endosomes, only active CatS was found in sizable amounts, colocalizing with C-terminal processing of the class II invariant chain and with cystatin C, the major endogenous Cat inhibitor. Late endosomes of human peripheral blood monocytes contain a well-controlled proteolytic machinery distinct from lysosomes, which is likely to play a key role in class II function.

<i>HMG‐X</i>, a <i>Xenopus</i> gene encoding an HMG1 homolog, is abundantly expressed in the developing nervous system (1994)

We used a PCR-based subtraction cloning procedure with Concanavalin A-treated and untreated animal caps from stage 9 Xenopus embryos to search for genes the expression of which is induced during neurogenesis. One of these genes was found to encode a homolog of mammalian HMG 1 and 2, hence named HMG-X. HMG-X mRNA was maternally transmitted, up-regulated in neuroectoderm-derived tissues throughout early development, and eventually down-regulated in all adult tissues examined except ovary. Our data suggest that we have identified a gene for a member of the HMG1/2 family that could have an important role in neurogenesis.
Liquid crystal lasers: coherent and incoherent microsources (2005)

In this paper, we review our recent experimental work on coherent and incoherent liquid crystal lasers. For the coherent lasers, results are presented on thin-film photonic band edge lasing using dye-doped low molar mass liquid crystals in the self-organised chiral nematic phase. We show that potentially high Q-factor lasers can be fabricated from these materials by demonstrating that a single mode output with a very narrow linewidth is readily achievable in well-aligned monodomain samples. Moreover, from our investigations we have found that the performance of the laser, i.e. the slope efficiency and the excitation threshold, are dependent upon the physical parameters of the low molar mass liquid crystal. Specifically, the slope efficiency was found to vary from 1% to 12% depending upon the liquid crystalline material employed. Using this information, the important parameters of the host liquid crystal are highlighted. As regards to the functionality, we demonstrate how the wavelength of the laser can be tuned using an in-plane electric field in a direction perpendicular to the helix axis. Finally, for the incoherent lasers, we summarise our findings on random lasers that are fabricated from liquid crystals which exhibit a smectic A* phase.
Erythropoietin therapy in patients with chronic renal failure. (1992)

Symptomatic anemia is a common complication of chronic renal failure. Treatment is now possible with the availability of recombinant human erythropoietin (epoetin alfa). Previous experimental studies have suggested that correcting the anemia of chronic renal failure may be harmful in that renal failure may be accelerated. Although experience with this drug has been primarily restricted to its use in patients with end-stage renal disease, several recent trials have been reported in patients with varying degrees of chronic renal failure. We review these studies with particular reference to the progression of renal failure and the drug's reported side effects. We conclude that the use of epoetin is beneficial and well tolerated and that there is no compelling evidence for the acceleration of renal failure associated with its use in patients.
Freeform fabrication and characterization of Zn‐air batteries (2008)

Purpose The paper's aim is to show the development of materials and methods which allow freeform fabrication of macroscopic Zn‐air electrochemical batteries. Freedom of geometric design may allow for new possibilities in performance optimization. Design/methodology/approach The authors have formulated battery materials which are compatible with solid freeform fabrication (SFF) while retaining electrochemical functionality. Using SFF processes, they have fabricated six Zn‐air cylindrical batteries and quantitatively characterized them and comparable commercial batteries. They analyze their performance in light of models from the literature and they also present SFF of a flexible two‐cell battery of unusual geometry. Findings Under continuous discharge to 0.25 V/cell with a 100 Ω load, the cylindrical cells have a specific energy and power density in the range of 40‐70 J/g and 0.4‐1 mW/cm 2 , respectively, with a mass range of 8‐18 g. The commercial Zn‐air button cells tested produce 30‐750 J/g and 7‐9 mW/cm 2 under the same conditions, and have a mass range of 0.2‐2 g. The two‐cell, flexible Zn‐air battery produces a nominal 2.8 V, open‐circuit. Research limitations/implications The freeform‐fabricated batteries have ∼10 percent of the normalized performance of the commercial batteries. High‐internal contact resistance, loss of electrolyte through evaporation, and inferior catalyst reagent quality are possible causes of inferior performance. Complicated material preparation and battery fabrication processes have limited the number of batteries fabricated and characterized, limiting the statistical significance of the results. Practical implications Performance enhancement will be necessary before the packaging efficiency and design freedom provided by freeform‐fabricated batteries will be of practical value. Originality/value The paper demonstrates a multi‐material SFF system, material formulations, and fabrication methods which together allow the fabrication of complete functional Zn‐air batteries. It provides the first quantitative characterization of completely freeform‐fabricated Zn‐air batteries and comparison to objective standards, and shows that highly unusual, functional battery designs incorporating flexibility, multiple cells, and unusual geometry may be freeform fabricated.
Some preservation of stability of modules (1997)

IN model theory, Zil’ ber has proved that any model of nontrivial -categorical theory is verysimilar to a module or field. So some people wanted to prove the famous Vaught’s conjec-ture for superstable theories of modules. Later, Buechler proved that the Vaught’s conjectureis true for the theories of modules with Morley rank 1. In order to reduce Vaught’s conjec-ture for superstablc theories of modules, Prest suggested discussing the preservation of stabili-ty--theory properties of modules when the underlying ring of the modules changes. Zieglergave some preservation theorems of clementary properties of the theory of modules in ref.
A taxonomy of behavior change techniques used in interventions. (2008)

Vaccines and Other Immunological Approaches for Cancer Immunoprevention (2011)

The immune system effectively prevents cancer, whereas severe immunodepression increases its incidence. Cancer immunoprevention is a strategy based on the concept that enhancement of tumor immunity in healthy individuals reduces cancer risk. It can be viewed as a kind of chemoprevention. For cancer immunoprevention, the cancer universe can be neatly divided between tumors caused - directly or indirectly - by infectious agents and all other tumors. Immunoprevention of tumors caused by infectious agents is already implemented at the population level for hepatitis B virus (HBV)-related hepatocellular carcinoma and for tumors caused by human papillomaviruses (HPV), like cervical carcinoma. Now the challenge is to develop immunological strategies to prevent the bulk ( > 80%) of human tumor burden, unrelated to infections. Both vaccines against tumor antigens and immune modulators can prevent tumor onset in cancerprone mice. These studies outlined the target antigens and the molecular and cellular mechanisms of cancer immunoprevention: a) the best target antigens are surface molecules controlling tumor growth and progression (oncoantigens); b) combinations of potent vaccines and nonspecific stimuli (adjuvants) yield the strongest protection; c) immunoprevention must start early in the natural history of tumors, before key progression events like the onset of carcinoma in situ; d) lifetime protection requires repeated boosts, to maintain a strong and steady immune response; e) antibodies and helper, rather than cytotoxic, T cells mediate long-term protection from tumor onset; f) immunoprevention can be combined with chemoprevention. The development of agents like tamoxifen, which went from cancer therapy to chemoprevention, could be a model for the translation of cancer immunoprevention from mice to humans.
GaAs wafer breakage: Causes and cures, growth and process (2002)

The impact of GaAs wafer breakage on processing facilities is discussed. Wafer strength and equipment assessment are detailed. The authors describe many of the improvements that have resulted in the virtual elimination of wafer breakage due to unassignable causes. When proper material and process control techniques are used, GaAs wafer breakage should not occur.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Building large-scale and corporate-wide case-based systems: integration of the organizational and machine executable algorithms (1992)

This paper reports a case study on a large-scale and corporate-wide case-based system. Unlike most papers for the AAAI conference, which exclusively focus on algorithms and models executed on computer systems, this paper heavily involves organizational activities and structures as a part of algorithms in the system. It is our claim that successful corporate-wide deployment of the case-base system must involve organizational efforts as a part of an algorithmic loop in the system in a broad sense. We have established a corporate-wide case acquisition algorithm, which is performed by persons, and developed the SQUAD Software Quality Control Advisor system, which facilitates sharing and spreading of experiences corporate-wide. The major findings were that the key for the success is not necessary in complex and sophisticated AI theories, in fact, we use very simple algorithms, but the integration of mechanisms and algorithms executed by machines and persons involved.
Space-time adaptive processing for distributed aperture radars (2004)

This paper furthers the development of signal processing for distributed, waveform diverse, antenna arrays. The long term goal is to develop practical waveform-time-space adaptive processing algorithms for distributed apertures. A crucial issue identified in previous works is that, in practice, the target and interfering sources are within the near-field of the antenna array. As a first step toward the long-term goal, this paper develops the model required to generate simulated data. Such a model would be particularly useful to develop and test new adaptive signal processing algorithms. Specifically, this paper develops a model for range dependent target and interference for distributed, frequency diverse, apertures.
Postpolycythemia myeloid metaplasia (1974)

From 1950 through 1955, a total of 207 patients were seen at the Mayo Clinic with a diagnosis of polycythemia vera; 29 developed postpolycythemia myeloid metaplasia (PPMM). The patients with PPMM tended to have more symptoms than patients with agnogenic myeloid metaplasia. In contrast to agnogenic myeloid metaplasia, these patients had more pressure symptoms and bleeding symptoms, a more lethal syndrome, and a shorter survival. Of 130 patients treated with sodium phosphate P 32 for polycythemia vera, 25 developed PPMM. No retrospective hematologic or clinical factors could be uncovered to predict subsequent development of metaplasia. Ten of the initial 207 patients developed acute leukemia. Five of these ten, all men, went through a metaplastic phase prior to the onset of their leukemic process. Males with polycythemia rubra vera who go through a metaplastic phase may be at higher risk for the subsequent development of acute leukemia.
The platelet-activating factor signaling system and its regulators in syndromes of inflammation and thrombosis (2002)

The PAF signaling system can trigger inflammatory and thrombotic cascades, amplify these cascades when acting with other mediators, and mediate molecular and cellular interactions (cross talk) between inflammation and thrombosis. Evidence from in vitro experiments, studies of experimental animals, and clinical observations in humans indicates that the PAF signaling system is important in sepsis and other syndromes of inflammatory injury and that therapeutic strategies to interrupt or terminate signaling via the PAF signaling system may be useful in these conditions.

A physically-based C/sub ∞/-continuous model for accumulation-mode SOI pMOSFETs (1999)

In this paper, we present a unified accumulation-mode (AM) SOI MOSFET model for circuit simulation. The model is valid in all the regimes of normal operation and includes explicit expressions of the drain current and total charges which have an infinite order of continuity; therefore, smooth transitions are assured. Short-channel effects have also been accounted for. We have finally proved that our model accurately fits the transistor characteristics for effective channel lengths down to 0.7-/spl mu/m.

ANTIBODY-INDUCED REJECTION OF PIG PROISLET XENOGRAFTS IN CD4+ T CELL-DEPLETED DIABETIC MICE (1990)

Reversal of diabetes in mice was achieved following in vivo depletion of host CD4+ T cells and transplantation of xenogeneic fetal pig proislets (pancreatic islet precursors). These procedures resulted in xenograft tolerance since established pig proislet xenografts were not rejected by antipig antibodies produced in the host, and rejection was not induced following the administration of donor major histocompatibility complex--specific pig lymphocytes. Proislet xenografts were rejected following the administration of donor MHC-specific hyper-immune antipig PBL serum raised in normal mice. Although established proislet xenografts in anti-CD4-treated mice are sensitive to antibody-mediated destruction, such hosts are unable to produce an antibody response that leads to graft rejection. The study indicates that the mechanism of preventing xenograft rejection by anti-CD4 treatment in vivo involves not only initial CD4+ T cell depletion but also quantitative and/or qualitative modulation of a CD4+ T cell-dependent antibody response. As a consequence, an apparent state of xenograft tolerance is produced.
