Broad-band power amplifier using dielectric photonic bandgap structure (1998)

Two class AB GaAs field-effect transistor (FET) power amplifiers have been designed and fabricated in the 4.4-4.8 GHz range. In the first case, a dielectric PBG line was incorporated in the design to tune the second harmonic. In the second case, a 50-/spl Omega/ line is used with no harmonic tuning. The PBG structure allows broad-band harmonic tuning and is inexpensive to fabricate. A 5% improvement in power-added efficiency was achieved at the design frequency of 4.5 GHz, in both simulation and measurement.

Performance evaluation of MR-proadrenomedullin and other scoring systems in severe sepsis with pneumonia. (2014)

The MR-proADM does not correlate with mortality or disease severity to predict mortality. The combination of SOFA, APACHE II scores, and MR-proADM was efficient to predict prognosis and mortality rate in severe sepsis or septic shock patients.
Implementation of an efficient parallel BDD package (1996)

Implementation of an Efficient Parallel BDD Package by Anthony L. Stornetta Large BDD applications are generally limited by a processor&apos;s resources, especially physical memory. In large BDD applications, virtual memory is not an attractive solution for conventional depth-first BDD algorithms. Irregular memory access patterns in the algorithm cause thrashing, which severely impairs performance. One solution to overcoming this resource limitation is to utilize the memory of multiple networked workstations. A number of different forms of parallelism can be exploited in depth-first algorithms performed on a distributed BDD. The BDD structure is stored in a distributed hash table and can be accessed simultaneously by multiple processors. An unlimited number of multiple BDD operations may be concurrently issued. In essence, the package can simultaneously execute multiple threads of computation on a distributed BDD. This thesis presents an efficient parallel BDD package for a distributed en...
Helper-free Production of Laboratory Grade AAV and Purification by Iodixanol Density Gradient Centrifugation (2018)

Adeno-associated virus (AAV) is one of the most promising gene therapy vectors and is widely used as a gene delivery vehicle for basic research. As AAV continues to become the vector of choice, it is increasingly important for new researchers to have access to a simplified production and purification protocol for laboratory grade recombinant AAV. Here we report a detailed protocol for serotype independent production of AAV using a helper-free HEK293 cell system followed by iodixanol gradient purification, a method described earlier.<sup>1</sup> While the core principals of this mammalian AAV production system are unchanged, there have been significant advancements in the production and purification procedure that serve to boost yield, maximize efficiency, and increase the purity of AAV preps. Using this protocol, we are able to constantly obtain high quantities of laboratory grade AAV particles (>5 × 10<sup>12</sup> vg) in a week's time, largely independent of serotype.
Solvolysis of Benzyl Alcohols and Ethers in 1,2-Diols and Application to a Deprotection of Benzyl Ether-type Protecting Groups (2006)

Abstract Some kinds of benzyl alcohols and ethers react with 1,2-diols, such as ethylene glycol and propylene glycol, at 130–190 °C to give 2-hydroxyethyl or 2-hydroxypropyl ethers. Application of this reaction to a deprotection of benzyl ether-type protecting groups, under neutral conditions, was also described.
Characteristics of SARS-CoV-2 and COVID-19 (2020)

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly transmissible and pathogenic coronavirus that emerged in late 2019 and has caused a pandemic of acute respiratory disease, named 'coronavirus disease 2019' (COVID-19), which threatens human health and public safety. In this Review, we describe the basic virology of SARS-CoV-2, including genomic characteristics and receptor use, highlighting its key difference from previously known coronaviruses. We summarize current knowledge of clinical, epidemiological and pathological features of COVID-19, as well as recent progress in animal models and antiviral treatment approaches for SARS-CoV-2 infection. We also discuss the potential wildlife hosts and zoonotic origin of this emerging virus in detail.
Constraints on the collision and the pre-collision tectonic configuration between India and Asia from detrital geochronology, thermochronology, and geochemistry studies in the lower Indus basin, Pakistan (2016)

Knowledge of the timing of India-Asia collision is a fundamental prerequisite for understanding the evolution of the Himalayan-Tibetan orogen and its role in global climate, oceanic chemistry, and ecological evolution. Despite much active research, the basic pre-collision tectonic configuration and the timing of terminal India-Asia suturing remain debated. For example, debates regarding when and how the intervening Kohistan-Ladakh arc was sutured with India and Asia still remain elusive; some models propose the arc collided with Asia at about 100 Ma, with India-Asia collision at ca. 55 Ma, whilst a newer model proposed the arc's collision with India at 50 Ma and subsequently with Asia at 40 Ma. Another example is the recent proposition that an oceanic Greater India Basin separated the Tethyan Himalaya microcontinent from the remaining Indian plate until 20-25 Ma with the consumption of this oceanic basin marking the final collision at this time. These controversies relate to whether the commonly documented 50 Ma contact represents the terminal India-Asia suturing or the amalgamation between various arcs or microcontinents with India or Asia. Here we present an integrated provenance study of geochronology, thermochronology, and geochemistry on the late Cretaceous-Pleistocene sediments from the lower Indus basin on the Indian plate. The detrital zircon U-Pb and fission track data show a reversal in sediment source from a pure Indian signature to increasing inputs from the suture zone and the Asian plate between the middle Paleocene and early Oligocene. The Nd and Sr isotopes narrow down this change to 50 Ma by revealing input of Asian detritus and the establishment of a Nd & Sr isotopic pattern similar to the present-day Indus Fan by 50 Ma, with no significant variations up section, contrary to what might be expected if later major collisions had occurred. Our isotopic data indicate that Greater India was occupied by a fluvial-deltaic system, analogous to the present-day Indus and named as the Paleo-Indus, which has been transporting Asian detritus southward across the suture zone and Kohistan-Ladakh arc since 50 Ma, suggesting no other ocean basins intervened between India and Asia after this time in this region. Our data require that in the west the India-Asia collision were accomplished by ~50 Ma.

Prospective Validation of a Modified Thrombolysis In Myocardial Infarction Risk Score in Emergency Department Patients With Chest Pain and Possible Acute Coronary Syndrome (2010)

The modified TIMI risk score outperformed the original with regard to overall diagnostic accuracy. However, it had lower specificity at all cut-points of >0, suggesting suboptimal risk stratification in high-risk patients. It also lacked sufficient sensitivity and specificity to safely guide patient disposition. Both scores are insufficiently sensitive and specific to recommend as the sole means of determining disposition in ED chest pain patients.
Antimicrobial activity of Mitracarpus scaber extract and isolated constituents (2000)

The antimicrobial activity of a methanol extract and isolated constituents of Mitracarpus scaber, a species used in folk medicine by West African native people, was evaluated against Staphylococcus aureus and Candida albicans strains. The mitracarpus methanol extract possesses both antibacterial and antimycotic activities (minimum inhibitory concentration-MIC 31.25 and 62.50 microg ml-, respectively). This extract was subsequently fractioned and monitored by bioassays leading to the isolation of seven compounds screened for antibacterial and antimycotic activities. Among these compounds, gallic acid and 3,4,5-trimethoxybenzoic acid inhibited the growth of Staph. aureus (MIC 3.90 and 0.97 microg ml-). 4-Methoxyacetophenone and 3,4,5-trimethoxyacetophenone effectively inhibited C. albicans (MIC 1.95 microg ml-). The other compounds (kaempferol-3-O-rutinoside, rutin and psoralen) which were also isolated showed low antibacterial and antimycotic activities (125-500 microg ml-).
Bounds for sparse planar and volume arrays (2001)

This paper improves and extends bounds on the numbers of sensors, redundancies, and holes for sparse linear arrays to sparse planar and volume arrays. As an application, the efficiency of regular planar and volume arrays with redundancies but no holes is deduced. Also, examples of new redundancy and hole square arrays, found by exhaustive computer search, are given.
PPM symbol synchronization in random data (2002)

The problem of achieving PPM (pulse position modulation) symbol synchronization using no reference marker but a finite span of slot observations is considered. The optimum maximum-likelihood (ML) decision statistics and the suboptimum, easily implementable maximum correlation decision statistics are derived for PPM symbol synchronization for the Poisson and Gaussian channels. Simulation results presented show that the PPM symbol synchronization probability performances of both decision statistics are practically identical for moderately high signal-to-noise ratios.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Simultaneous expression of recombinant baculovirus-encoded chicken anaemia virus (CAV) proteins VP1 and VP2 is required for formation of the CAV-specific neutralizing epitope. (1998)

Chicken anaemia virus (CAV) expresses three proteins, VP1, VP2 and VP3, but its capsid contains only the VP1 protein. In this paper, we report that for production of the neutralizing epitope, co-synthesis of (recombinant) VP1 and VP2 has to take place. We show via immunofluorescence that recombinant-baculovirus-infected Sf9 cells synthesizing VP1 (or VP2) alone react very poorly with CAV-specific neutralizing antibodies. In contrast, Sf9 cells co-infected with VP1- and VP2-recombinant baculoviruses, or infected with a single recombinant baculovirus co-expressing both VP1 and VP2, react strongly with the neutralizing antibodies. Furthermore, immunoprecipitation assays show that VP1 and VP2 interact directly with each other, which indicates that the non-structural protein VP2 might act as a scaffold protein in virion assembly. Recombinant baculovirus expressing VP1 and VP2 is, therefore, a potential production system for a subunit vaccine against CAV infection.

Abnormal High Rate Deposition of TiN films by the Radio Frequency Plasma Jet System (1995)

Radio frequency Ar and plasma jets generated in a hollow electrode terminated by a small size Ti nozzle were used for deposition of Ti and films. The regime with low content of reactive gas resulted in an extreme enhancement of deposition rate, more than one order higher than that of Ti. Abrupt increase of the nozzle temperature to >1350°C in this regime is caused by additional thermal energy imparted to the nozzle. Abrupt decrease of the cathode dc self‐bias and simultaneous steep increase of the optical emission from Ti and from ions Ti+, , and Ar+ indicate the transition of the discharge into the RPJ‐arc. This reflects in an enhanced production of Ti and Ti+ which leads to a high rate (≈μm/min) growth of films. The microhardness of films at low nitrogen content is and the film resistivity is 80 μΩ cm. Geometry of the particle transport and the distribution of the, film thickness on substrates confirm a hollow profile of the particle density distribution in the plasma jet.
Evidence of Serological Cross-Reactivity between Genotype 1 and Genotype 3 Erythrovirus Infections (2005)

Candotti and colleagues (1) reported the prevalence of a third strain of human erythrovirus, genotype 3 (V9), in the Ghanaian population and, in part, concluded that a genotype 1 (B19)-based assay failed to detect genotype 3 immunoglobulin G (IgG) in 38.5% of Ghanaian samples containing genotype 3 antibodies. We disagree with this conclusion for the following reasons. (i) No details are furnished as to the expression system used for V9 VP1 production, the conformational status of the protein (denatured or native structure), or the purity or the concentration of the genotype 3 VP1 protein used for microplate coating. (ii) The number of specimens used to establish the cutoff of the V9 VP1 enzyme immunoassay (EIA) was extremely small (n = 4). (iii) The high degree of homology among capsid proteins of genotypes 1 through 3 would suggest that antibodies raised against one capsid type would be cross-reactive with the others (3, 7).
Libertad for All? Why the Helms-Burton Act Is an Empty Promise of “Freedom” for the Cuban People. (2020)

After the Cuban Revolution, the Castro government nationalized the property of many American nationals, which served as a justification for the Kennedy administration’s decision to institute a general economic embargo on Cuba. This embargo was officially codified in the late 1990s in the Cuban Liberty and Democratic Solidarity (Libertad) Act, enacted by President Bill Clinton. Title III of this Act was suspended since its enactment. By creating a private cause of action for American nationals to sue “traffickers” of their improperly nationalized Cuban property, Title III aims to deter foreign investment into Cuba and compensate American citizens whose Cuban property interests were improperly nationalized during the Cuban Revolution. Recently, the Trump Administration decided to lift the suspension of Title III of the Helms-Burton Act, allowing American nationals to sue these “traffickers.” Title III of the Helms-Burton Act compromises the separation of powers articulated by the U.S. Constitution, violates international and domestic standards of legislative extraterritoriality, and will violate the due process rights of many defendants in these suits. While federal courts should find Title III unconstitutional on these grounds, or at least construe the statute narrowly to reduce the potential of frivolous suits, the most effective means for settling these outstanding property claims is to negotiate with the Cuban government in an arbitral tribunal modeled after the Iranian-United States Claims Tribunal.
Two-photon optical-beam-induced current solid-immersion imaging of a silicon flip chip with a resolution of 325 nm (2005)

We report high-resolution subsurface imaging of a silicon flip chip by detection of the photocurrent generated by the two-photon absorption of 1530-nm light from a femtosecond Er:fiber laser. The technique combines the focal sensitivity of two-photon excitation with the enhanced optical resolution of high-numerical-aperture solid-immersion imaging. Features on a sub-1-microm scale are clearly resolvable with high contrast, showing a resolution of 325 nm.
A cleanroom in a glovebox (2020)

The exploration of new materials, novel quantum phases, and devices requires ways to prepare cleaner samples with smaller feature sizes. Initially, this meant the use of a cleanroom that limits the amount and size of dust particles. However, many materials are highly sensitive to oxygen and water in the air. Furthermore, the ever-increasing demand for a quantum workforce, trained and able to use the equipment for creating and characterizing materials, calls for a dramatic reduction in the cost to create and operate such facilities. To this end, we present our cleanroom-in-a-glovebox, a system that allows for the fabrication and characterization of devices in an inert argon atmosphere. We demonstrate the ability to perform a wide range of characterization as well as fabrication steps, without the need for a dedicated room, all in an argon environment. Finally, we discuss the custom-built antechamber attached to the back of the glovebox. This antechamber allows the glovebox to interface with ultra-high vacuum equipment such as molecular-beam epitaxy and scanning tunneling microscopy.
[Haemocoagulative modifications correlated with pregnancy]. (2006)

These findings suggest that normal pregnancy is associated with an hypercoagulable state, resulting into a moderate risk for thrombosis during the different trimesters of pregnancy. Also broad spectrum assays which measure a range of trombin/fibrin formation in serum have become an established mean to identify activation of blood coagulation and/or fibrinolysis. There is a considerable interest in the application of these assays to the diagnosis of other acquired hypercoagulable states; such as thrombophilia during pregnancy. From the viewpoint of coagulation/fibrinolysis changes, the follow-up of thrombophilia markers could be recommended when levels of coagulation parameters exceed the normal values during pregnancy.
<i>So</i> FAR: Software for Fully Automatic Evaluation of Real-Time PCR Data (2003)

Quantitative real-time PCR has proven to be an extremely useful technique in life sciences for many applications. Although a lot of attention has been paid to the optimization of the assay conditions, the analysis of the data acquired is often done with software tools that do not make optimum use of the information provided by the data. Particularly, this is the case for high-throughput analysis, which requires a careful characterization and interpretation of the complete data by suitable software. Here we present a software solution for the robust, reliable, accurate, and fast evaluation of real-time PCR data, called SoFAR. The software automatically evaluates the data acquired with the LightCycler system. It applies new algorithms for an adaptive background correction of signal trends, the calculation of the effective signal noise, the automated identification of the exponential phases, the adaptive smoothing of the raw data, and the correction of melting curve data. Finally, it provides information regarding the validity of the results obtained. The SoFAR software minimizes the time required for evaluation and increases the accuracy and reliability of the results. The software is available upon request.
Effect of AlN/GaN superlattice buffer on the strain state in GaN-on-Si(111) system (2014)

The effect of AlN/GaN superlattice (SL) buffer on the strain state in a GaN-on-Si(111) system was studied in detail by room-temperature micro-Raman scattering measurement. An abnormal satellite peak attached to a GaN E2 peak was observed, which was verified to stem from the compressively strained GaN in SLs. The results indicate that the strain-sensitive GaN E2 (high) peak in the GaN-on-Si system with AlN/GaN SLs splits into two peaks because the GaN stress state in the top GaN layer is different from that in SLs. The compressive stress in the GaN layer in SLs was introduced by the AlN layer in each SL period because of the lattice mismatch between GaN and AlN, which ultimately counterbalanced the tensile stress in the top GaN during cooling. Such a counterbalance interaction is strongly dependent on the stiffness coefficient of AlN/GaN SLs, which is proportional to the number of periods of SLs and the relative thickness of AlN in SLs. Such two E2 peaks from GaN enable us to monitor the strain state in the GaN-on-Si system with AlN/GaN SLs quantitatively.
