Emergence of Human Angiohematopoietic Cells in Normal Development and from Cultured Embryonic Stem Cells (2007)

Human hematopoiesis proceeds transiently in the extraembryonic yolk sac and embryonic, then fetal liver before being stabilized in the bone marrow during the third month of gestation. In addition to this classic developmental sequence, we have previously shown that the aorta-gonad-mesonephros (AGM) embryonic territory produces stem cells for definitive hematopoiesis from 27 to 40 days of human development, through an intermediate blood-forming endothelium stage. These studies have relied on the use of traditional markers of human hematopoietic and endothelial cells. In addition, we have recently identified and characterized a novel surface molecule, BB9, which typifies the earliest founders of the human angiohematopoietic system. BB9, which was initially identified with a monoclonal antibody raised to Stro-1(+) bone marrow stromal cells, recognizes in the adult the most primitive Thy-1(+) CD133(+) Lin(-), non-obese diabetic--severe combined immunodeficiency disease (NOD-SCID) mouse engrating hematopoietic stem cells (HSCs). In the 3- to 4-week embryo, BB9 expression typifies a subset of splanchnopleural mesodermal cells that migrate dorsally and colonize the ventral aspect of the aorta where they establish a population of hemogenic endothelial cells. We have indeed confirmed that hematopoietic potential in the human embryo, as assessed by long-term culture-initiating cell (LTC-IC) and SCID mouse reconstituting cell (SRC) activities, is confined to BB9-expressing cells. We have further validated these results in the model of human embryonic stem cells (hESCs) in which we have modeled, through the development of hematopoietic embryoid bodies (EBs), primitive and definitive hematopoieses. In this setting, we have documented the emergence of BB9(+) hemangioblast-like clonogenic angiohematopoietic progenitors that currently represent the earliest known founders of the human vascular and blood systems.

Making SVG a Web Service in a Message-based MVC Architecture (2004)

We reformulate Scalable Vector Graphics browser in a Web Service architecture separating the rendering from the W3C DOM processing of events. We describe this in a message-based Model-View-Controller (M-MVC) architecture and implement it with a powerful publish-subscribe messaging infrastructure. A Web Services oriented architecture with services loosely coupled by the exchange of messages is becoming an increasingly important feature in the deployment of Internet applications. The broad applicability of this approach includes enterprise software, e-Learning, e-Science and e-Business. Our work provides a general framework for integrating Desktop and Web Service applications. We summarize the performance results from detailed tests of our prototype. These measurements demonstrate the viability of our approach and identify some key issues influencing the performance of message-based Web and Desktop applications. We note how our architecture elegantly supports the major paradigms for collaboration. 1.
Sphenopalatine Ganglion Pulsed Radiofrequency Treatment in 30 Patients Suffering from Chronic Face and Head Pain (2005)

This study evaluated the efficacy of sphenopalatine ganglion pulsed radiofrequency (SPG-PRF) treatment in patients suffering from chronic head and face pain. Thirty patients were observed from 4 to 52 months after PRF treatment. The primary efficacy measures were the reduction in oral medication use, including opioids, time-to-next-treatment modality for presenting symptoms, duration of pain relief, and the presence of residual symptoms. Secondary objectives included the evaluation of adverse effects and complications. All data were derived from patient charts, phone conversations, and clinical follow-up visits. Fourteen percent of respondents reported no pain relief, 21% had complete pain relief, and 65% of the patients reported mild to moderate pain relief from SPG-PRF treatment. Sixty-five percent of the respondents reported mild to moderate reduction in oral opioids. None of the patients developed significant infection, bleeding, hematoma formation, dysesthesia, or numbness of palate, maxilla, or posterior pharynx. A large-scale study of SPG-PRF for the treatment of face and head pain has not been previously reported. Our results suggest that a prospective, randomized, controlled trial study to confirm efficacy and safety of this novel treatment for chronic head and face pain is justified.
An unsupervised framework for extracting and normalizing product attributes from multiple web sites (2008)

We have developed an unsupervised framework for simultaneously extracting and normalizing attributes of products from multiple Web pages originated from different sites. Our framework is designed based on a probabilistic graphical model that can model the page-independent content information and the page-dependent layout information of the text fragments in Web pages. One characteristic of our framework is that previously unseen attributes can be discovered from the clue contained in the layout format of the text fragments. Our framework tackles both extraction and normalization tasks by jointly considering the relationship between the content and layout information. Dirichlet process prior is employed leading to another advantage that the number of discovered product attributes is unlimited. An unsupervised inference algorithm based on variational method is presented. The semantics of the normalized attributes can be visualized by examining the term weights in the model. Our framework can be applied to a wide range of Web mining applications such as product matching and retrieval. We have conducted extensive experiments from four different domains consisting of over 300 Web pages from over 150 different Web sites, demonstrating the robustness and effectiveness of our framework.
Millimeter-Wave Filtering Reflectarray for High-Gain Antenna Applications (2019)

This paper proposes a new concept of high-gain filtering reflectarray antenna operating at millimeter-wave (mmW) frequencies. Two-section metal waveguide element is used as the reflectarray unit cell. Taking advantage of the high-pass filter nature of the waveguide structure, the reflectarray elements can provide desired reflection coefficients in the targeted band of interest yet deteriorating reflection phase and amplitude responses at lower and upper out-of-band frequencies, respectively. Therefore, the proposed reflectarray can realize filter-like frequency response by controlling the aperture amplitude and phase distributions. The antenna has been fabricated by low-cost 3-dimentional (3-D) printing technique followed by metal coating. Both simulated and measured results are presented to verify its radiating and filtering functions.
Einleitung (2003)

Die Holzbranche gehört in Deutschland zu den Wirtschaftszweigen mit überdurchschnittlichen Energieumsätzen. Von der Erstbearbeitung des eingeschlagenen Holzes im Sägewerk über die verschiedenen Stufen der Holzbearbeitung bis zur Herstellung bzw. Montage der unterschiedlichsten Endprodukte werden erhebliche Energiemengen in Form von Strom und Wärme eingesetzt. Ein wesentlicher Teil dieser Energiemengen dient nicht dem eigentlichen Bearbeitungsschritt sondern der Deckung von Energie Verlusten.
Acute Effects of β <sub>1</sub> -Selective and Nonselective β-Adrenergic Receptor Blockade on Cardiac Sympathetic Activity in Congestive Heart Failure (1996)

The administration of a beta 1-selective antagonist was associated with increased cardiac norepinephrine spillover. In contrast, the administration of a nonselective beta-blocker until similar hemodynamic end points were reached caused a reduction in norepinephrine spillover. This suggests that in patients with heart failure, nonselective beta-blockade may have favorable inhibitory effects on cardiac sympathetic activity.
On the Hydrodynamic Forces for Shallow Draft Ships in Shallow Water (3rd Report) (1980)

The hydrodynamic forces of pitch mode on a circular disk as a shallow draft ship in shallow water are investigated. The boundary value problem is formulated by the use of the concept of the surface distributed sources so that integral equation for the source densities are obtained. In the case of long waves, the problem is solved analytically. The numerical solution of the integral equation is found. The added moment of inertia, wave damping factor, wave exciting moment, radiation pressures, wave exciting pressures and motions are calculated. The corresponding experiments are carried out and the results of the numerical calculation are in good agreement with those of the experiments.
An analysis of miniaturized dual-mode bandpass filter structure using shunt-capacitance perturbation (2005)

A dual-mode bandpass ring filter using two pairs of shunt capacitances has been analyzed and designed. The size of the ring resonator can be reduced significantly by increasing the shunt capacitances. Since the resonator size is not an integer multiple of operating frequency, harmonic suppression is easily achieved. Analysis shows that the two pairs of shunt capacitances independently control the even- and odd-mode resonant frequency of the ring resonator. Moreover, the shunt capacitance also allows easier biasing, making tunable filters using varactors realizable. Various configurations of dual-mode bandpass filters have been reported, and the advantages and disadvantages of each structure are discussed. Several filters of various capacitances have been designed and tested at 1.8 GHz, and show significant size reduction of over 67%. A varactor-tuned filter has also been designed, and demonstrated a measured tunable center frequency of 20%. This study is a solution to the miniaturization of ring filters, and allows performance tuning, making ring filters more attractive in monolithic microwave integrated circuits and system-on-chip applications.

Effect of crystallization heat treatment on the microstructure and biaxial strength of fluorrichterite glass‐ceramics (2006)

The purpose of this study was to evaluate the effect of crystallization heat treatment on the flexural strength of potassium fluorrichterite glass-ceramics for biomedical applications. After melting and casting, discs were sectioned from the glass ingots, randomly divided into 10 groups, and heat treated at various temperatures ranging between 890 degrees C and 925 degrees C for various durations. One group was air-abraded after heat treatment. XRD revealed the presence of fluorrichterite and fluormica for all heat-treated groups. SEM confirmed the presence of both fluorrichterite and fluormica crystals. Crystal size increased with temperature and duration of the heat treatment. The mean flexural strength after air abrasion was not significantly different than that of the other groups except the group heat treated at 925 degrees C. The mean flexural strength was maximum after heat treatment at 900 degrees C for 1 h (497.6 +/- 25.5 MPa) and decreased linearly with the longer durations of heat treatment at 900 degrees C.

A Detective Story in Drug Discovery: Elucidation of a Screening Artifact Reveals Polymeric Carboxylic Acids as Potent Inhibitors of RNA Polymerase (2013)

Chasing the active impurity: In the validation of a screening hit it was discovered that a polymeric trace impurity was responsible for the biological activity. Such a side product can be formed with similar compounds. During the investigations it was discovered that the negatively charged macromolecule interacts very efficiently with the protein surface of E. coli RNAP via electrostatic interactions.
A Novel Signaling Pathway Mediates the Inhibition of CCL3/4 Expression by Prostaglandin E2 (2004)

In response to pathogen-associated molecular patterns, dendritic cells initiate an innate immune response characterized by expression and release of proinflammatory cytokines and chemokines. The extent of the inflammatory response is limited by various endogenous factors, including lipid mediators such as prostaglandin E(2) (PGE(2)). We described previously the inhibitory effect of PGE(2) on the expression and release of the inflammatory chemokines CCL3 and CCL4 from activated dendritic cells. In this study we describe a novel PGE(2) signaling pathway that proceeds through EP-2 --> cAMP --> EPAC --> phosphatidylinositol 3-kinase --> protein kinase B --> GSK-3 and results in increased DNA binding of the CCAAT displacement protein (CDP), a potent mammalian transcriptional repressor. The direct link between CDP and CCL3/4 transcription was established in knock-down experiments using CDP small interference RNA.
Bandwidth Adjustable DVTS on the Heterogeneous Internet Environments for Distance Learning (2007)

We propose a new schematic design for sending and receiving a digital video stream on the heterogeneous Internet environment such as a Gigabit Ethernet and a narrow bandwidth satellite link. On such network, a sender can send the full 30fps digital video stream, but not all sites can receive a full quality video. In our proposed scheme, a DVTS repeater named Dvrelay is introduced to reduce frame rate of a DVTS stream going through it. To receive site-aware quality of DVTS stream, Dvrelay can be set up at the nearest point to the receiver site and it can thin out frames to adjust the transmission rate for the narrow bandwidth environment. With this scheme, it is not necessary to modify DVTS sender and receiver. Therefore, it can apply to any DVTS environments and adjust traffic according to capacity of the network links available to recipients. Consequently, all sites in the Internet can receive the site-aware best quality of digital video stream. Then all sites in the Internet can receive the lecture with the quality of the digital video
Isogeny cycles and the Schoof-Elkies-Atkin algorithm (1996)

. The heart of Schoof&apos;s algorithm for computing the cardinality m of an elliptic curve over a finite field is the computation of m modulo small primes `. Elkies and Atkin have designed practical improvements to the basic algorithm, that make use of &quot;good&quot; primes `. We show how to use powers of good primes in an efficient way. This is done by computing isogenies between curves over the ground field. We investigate the properties of the &quot;isogeny cycles&quot; that appear. 1. Introduction Let E be an elliptic curve over a finite field F q where q = p r , p prime. The curve is given by some equation E(X; Y ) = 0 in Weierstrass form E(X; Y ) = Y 2 + a 1 XY + a 3 Y \\Gamma (X 3 + a 2 X 2 + a 4 X + a 6 ) so that a generic point on the curve is given by (X; Y ) mod E . Let m be the number of points of E. It is well known that m = q + 1 \\Gamma t, with t an integer satisfying jtj 2 p q. If q is small the problem of computing the cardinality of E is easy: one can simply enumerate all the p...
Poissona, Shannon, and the Radio Amateur (1959)

Congested band operation as found in the amateur service presents an interesting problem in analysis which can only be solved by statistical methods. Consideration is given to the relative merits of two currently popular modulation techniques, SSB and DSB. It is found that in spite of the bandwidth economy of SS13 this system can claim no over-all advantage with respect to DSB for this service. It is further shown that there are definite advantages to the use of very broadband techniques in the amateur service. The results obtained from the analysils of the radio amateur service are significant, for they challenge the intuitively obvious and universally accepted thesis that congestion in the radio frequency spectrum can only be relieved by the use of progressively smaller transmission bandwidths obtained by appropriate coding and modulation techniques. In order to study the general problem of spectrum utilization, some basic results of information theory are required Some of the significant work of Shannon is reviewed with special emphasis on his channel capacity formula. It is shown that this famous formnula, in spite of its deep philosophical significance, cannot be used meaningfully in the analysis and design of practical, present day communications systems. A more suitable channel capacity formula is derived for the practical case. The analytical results thus obtained are used to show that broadband techniques have definite merit for both civil and military applications.
Ultralow-Voltage Transparent $\hbox{In}_{2} \hbox{O}_{3}$ Nanowire Electric-Double-Layer Transistors (2011)

Ultralow-voltage (0.4 V) operation of such a device is realized due to the extremely large electric-double-layer (EDL) capacitance (8.93 at 20 Hz) of the composite solid electrolyte. The subthreshold slope and equivalent field-effect mobility of the transparent nanowire EDL transistors are estimated to be 70 mV/dec and 739.7 , respectively. Such ultralow-voltage transparent nanowire transistors are promising for portable invisible sensors.
The Copper Oxide Rectifier (1936)

The equilibrium diagram of the copper: copper oxide: oxygen system controls the conditions of formation of the cuprous oxide rectifier. The interface between the cuprous oxide and the copper from which it is formed can be studied with polarized light. Intimate contact exists for more than half the total area. The technique of preparing the rectifier has a marked influence on its characteristics. By using a method of measuring the resistance characteristic which did not cause an error due to current heating at the interface, unusual results were obtained from specimens made under various conditions. Measurement of the thermal conductance of the rectifier disclosed a new physical phenomenon, asymmetrical thermal conductance. This asymmetry is in the direction that would be expected from the electron theory of heat conduction.
Aqueous electrolyte system for porous silicon using electrochemical anodization (2013)

Electrochemical anodization on n-type silicon was performed with silicon as anode and platinum as cathode in a weak-acid aqueous electrolyte containing orthophosphoric acid and ammonium fluoride. Anodization was carried out in two different modes, i.e., potentiostatic and galvanostatic with the voltage and current density of 5-80 V and 10-50 mA/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> respectively. Anodization time was varied from 5 min to 10 hours. Morphology of the anodized samples was studied using scanning electron microscopy (SEM), revealing the formation of pores with uniform distribution throughout the silicon substrate. The pore size and density were controllable by varying the anodization voltage and current. Results showed that, in a broad spectrum range of 400-1100 nm, the total reflectance (sum of diffused and specular reflectance) of the porous silicon was about 10% compared to >30% of the as-received silicon wafer. The porous silicon is promising for solar cell applications due to the low reflection loss.
