An X-band reconfigurable bandpass filter using phase change RF switches (2016)

In this paper, we report on a reconfigurable bandpass filter for X-band applications. The filter is composed of coupled X/2 microstrip line resonators. Center frequency tuning of each resonator is achieved using an RF switch based on a phase change chalcogenide compound, germanium telluride, which switches in and out a loading capacitor. A combination of electric and magnetic coupling between the resonators realizes a near constant absolute-bandwidth as the filter is tuned. The center frequency of the filter is switched between 7.45 and 8.07 GHz, with a 3-dB bandwidth of ~ 500 MHz, insertion loss of less than 3.2 dB, and return loss of better than 18 dB. The measured third-order intermodulation intercept point (IIP3) and 1-dB power compression point (P1dB) are better than 30 dBm at frequency offset of 1 kHz and 25 dBm, respectively. Measured and simulated results are in good agreement. To our best knowledge, this is the first time implementation of a tunable filter using germanium telluride based phase change switches.
Equilibrium melting of plasmid ColE1 DNA: electron-microscopic visualization (1980)

The fine structure of the melting curve for the linear colE1 DNA has been obtained. To find the ColE1 DNA regions corresponding to peaks in the melting curve's fine structure, we fixed the melted DNA regions with glyoxal /12/. Electron-microscopic denaturation maps were obtained for nine temperature points within the melting range. Thereby the whole process of colE1 DNA melting was reconstructed in detail. Spectrophotometric and electron microscopic data were used for mapping the distribution of Gc-pairs over the DNA molecule. The most AT-rich DNA regions (28 and 37% of GC-pairs), 380 and 660 bp long resp., are located on both sides of the site of ColE1 DNA's cleavage by EcoR1 endonuclease. The equilibrium denaturation maps are compared with maps obtained by the method of Inman /20/ for eight points of the kinetic curve of ColE1 DNA unwinding by formaldehyde.
Reflex HMD to compensate lag and correction of derivative deformation (2003)

A head-mounted display (HMD) system suffers largely from the time lag between human motion and the display output. The concept of a reflex HMD to compensate for the time lag is proposed and discussed. Based on this notion, a prototype reflex HMD is constructed. The rotational movement of the user's head is measured by a gyroscope, modulating the driving signal for the LCD panel, and this shifts the viewport within the image supplied from the computer. The derivative distortion was investigated, and the dynamic deformation of the watched world was picked up as the essential demerit. Cylinderical rendering is introduced to solve this problem and is proved to cancel this dynamic deformation, and also to decrease the static distortion.

3-D shape indexing language (1990)

The authors propose an indexing method that allows a 3-D shape database to be accessed with descriptive words or 2-D images, both of which are very intuitive and powerful. The new 3-D shape-indexing method uses superquadrics. First, the requirements for 3-D indexing are given. From an estimation of 3-D modeling methods, the superquadric model is found to be most suitable, and its performance is discussed. Applications of this 3-D indexing method to man-machine communications are given. first, the authors show that a modeled 3-D object can be easily deformed by verbal instruction, such as 'rounder' and 'squarer'. Second, they prove that the shape abstraction of a 3-D object is easily created from two rough sketches showing the cross-sections of the object. And finally, an experimental 3-D image database system that makes good use of this indexing method is created. This new indexing method promises to revolutionize 3-D visual communication and database systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Real-time pose estimation of deformable objects using a volumetric approach (2014)

Pose estimation of deformable objects is a fundamental and challenging problem in robotics. We present a novel solution to this problem by first reconstructing a 3D model of the object from a low-cost depth sensor such as Kinect, and then searching a database of simulated models in different poses to predict the pose. Given noisy depth images from 360-degree views of the target object acquired from the Kinect sensor, we reconstruct a smooth 3D model of the object using depth image segmentation and volumetric fusion. Then with an efficient feature extraction and matching scheme, we search the database, which contains a large number of deformable objects in different poses, to obtain the most similar model, whose pose is then adopted as the prediction. Extensive experiments demonstrate better accuracy and orders of magnitude speed-up compared to our previous work. An additional benefit of our method is that it produces a high-quality mesh model and camera pose, which is necessary for other tasks such as regrasping and object manipulation.
High-harmonic generation from Bloch electrons in solids (2015)

We study the generation of high-harmonic radiation by Bloch electrons in a model transparent solid driven by a strong midinfrared laser field. We solve the single-electron time-dependent Schrödinger equation (TDSE) using a velocity-gauge method [M. Korbman, New J. Phys. 15, 013006 (2013)NJOPFM1367-263010.1088/1367-2630/15/1/013006] that is numerically stable as the laser intensity and number of energy bands are increased. The resulting harmonic spectrum exhibits a primary plateau due to the coupling of the valence band to the first conduction band, with a cutoff energy that scales linearly with field strength and laser wavelength. We also find a weaker second plateau due to coupling to higher-lying conduction bands, with a cutoff that is also approximately linear in the field strength. To facilitate the analysis of the time-frequency characteristics of the emitted harmonics, we also solve the TDSE in a time-dependent basis set, the Houston states [J. B. Krieger and G. J. Iafrate, Phys. Rev. B 33, 5494 (1986)PRBMDO1098-012110.1103/PhysRevB.33.5494], which allows us to separate interband and intraband contributions to the time-dependent current. We find that the interband and intraband contributions display very different time-frequency characteristics. We show that solutions in these two bases are equivalent under a unitary transformation but that, unlike the velocity-gauge method, the Houston state treatment is numerically unstable when more than a few low-lying energy bands are used.
Fibroblasts transfected with Torpedo acetylcholine receptor beta-, gamma-, and delta-subunit cDNAs express functional receptors when infected with a retroviral alpha recombinant. (1989)

Torpedo californica acetylcholine receptor (AChR) alpha-, beta-, gamma-, and delta-subunit cDNAs were each stably introduced into muscle and/or fibroblast cell lines using recombinant retroviral vectors and viral infection, or using SV-40 vectors and DNA-mediated cotransfection. The expressed proteins were characterized in terms of their molecular mass, antigenicity, posttranslational processing, cell surface expression, stability in fibroblasts, stability in differentiated and undifferentiated muscle cells, and ability (of alpha) to bind alpha-bungarotoxin (BuTx). We demonstrated that the alpha, beta, gamma, and delta polypeptides acquired one, one, two, and three units of oligosaccharide, respectively. If all four subunits were expressed in the same cell, fully functional cell surface AChRs were produced which had a Kd for BuTx of 7.8 X 10(-11) M. In contrast, subunits expressed individually were not detected on the surface of fibroblasts and the Kd for BuTx binding to individual alpha polypeptides was only approximately 4 X 10(-7) M. The half-lives of the alpha, gamma, and delta subunits at 37 degrees C were all found to be quite short (approximately 43 min), while the half-life of the beta subunit was found to be even shorter (approximately 12 min). The unique half-life of the beta subunit suggests that it might perform a key regulatory role in the process of AChR subunit assembly. One stable fibroblast cell line was established by transfection that expressed beta, gamma, and delta subunits simultaneously. When this cell line was infected with a retroviral alpha recombinant, fully functional cell surface AChRs were produced. The successful expression of this pentameric protein complex combining transfection and infection techniques demonstrates one strategy for stably introducing the genes of a heterologous multisubunit protein complex into cells.
Comparative Study Parallel Join Algorithms for MapReduce environment (2012)

There are the following techniques that are used to analyze massive amounts of data: MapReduce paradigm, parallel DBMSs, column-wise store, and various combinations of these approaches. We focus in a MapReduce environment. Unfortunately, join algorithms is not directly supported in MapReduce. The aim of this work is to generalize and compare existing equi-join algorithms with some optimization techniques.
Recovering in large distributed systems with replicated data (2002)

The problem of recovery in large-scale transaction-based distributed systems with replicated data is studied. In large distributed systems the cost of accessing data items may be considerably greater, because of the distances involved. It is thus important to exploit replication to reduce data-access times. Also, in large systems, failure events are much more frequent than in small systems. Therefore, executing costly recovery protocols, such as the ones needed to update stale, newly-recovered replicas or to resolve the uncertainty of recovering replicas, must be avoided. These protocols are called dependent recovery protocols, since they require a recovering site to consult other sites before it can be reintegrated into the distributed system. Independent recovery has been proved unattainable in one-copy systems. It is shown that independent recovery is possible in systems with replicated data by contributing such a protocol. Simulation and analytical studies of its performance and availability characteristics are reported.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A source-synchronous I/O architecture is reported that includes redundant receiver lanes to enable lane recalibration with reduced power and area overhead. Key features and considerations of the proposed architecture are described. A proof-of-concept 16 lane, 16 Gb/s per lane source-synchronous I/O test chip was designed and fabricated in a 32 nm SOI CMOS technology. Several circuit techniques employed in the design of this test chip are described. These include a phase rotator based on current-integrating phase interpolator cores with architecture and circuit improvements to performance as compared to prior art, an active-inductor-based RX CTLE, and an 8:1 TX serializer with 8-phase clocking. Measurements demonstrate the operation of the test chip over ultra-short-reach channels with up to 10 dB of loss with greater than 30% timing margin. The I/O circuitry operates from 1 V supplies and achieves a power efficiency of better than 2 pJ/bit, making the proposed architecture suitable for use in high-density interconnect applications required for high-performance computing systems.

Simple slew-rate control technique cuts switching losses (2019)

The reduction of switching losses in power electronic systems such as drives is limited by EMI or parameters like the slope of switched voltages. This behavior is usually fixed by selecting the effective gate resistance of power transistors. It cannot be adapted spontaneously during operation. This paper shows a simple way to overcome this dilemma by operating conventional gate-driver ICs in parallel. Characterization data evaluations are presented for both a discrete IGBT IKW40N120T2 and a discrete silicon-carbide MOSFET IMW120R045M1.
Wearable Movement Sensors for Rehabilitation: A Focused Review of Technological and Clinical Advances (2018)

Recent technologic advancements have enabled the creation of portable, low-cost, and unobtrusive sensors with tremendous potential to alter the clinical practice of rehabilitation. The application of wearable sensors to track movement has emerged as a promising paradigm to enhance the care provided to patients with neurologic or musculoskeletal conditions. These sensors enable quantification of motor behavior across disparate patient populations and emerging research shows their potential for identifying motor biomarkers, differentiating between restitution and compensation motor recovery mechanisms, remote monitoring, telerehabilitation, and robotics. Moreover, the big data recorded across these applications serve as a pathway to personalized and precision medicine. This article presents state-of-the-art and next-generation wearable movement sensors, ranging from inertial measurement units to soft sensors. An overview of clinical applications is presented across a wide spectrum of conditions that have potential to benefit from wearable sensors, including stroke, movement disorders, knee osteoarthritis, and running injuries. Complementary applications enabled by next-generation sensors that will enable point-of-care monitoring of neural activity and muscle dynamics during movement also are discussed.

Antibody therapy for Lassa fever (2019)

Serum from convalescent Lassa fever patients was previously shown to be ineffective as a source of protective antibodies in some early studies. Subsequently, monoclonal antibodies (MAbs) to the Lassa virus (LASV) glycoprotein produced by memory B cells of West African patients who survived Lassa fever were identified. Development of MAbs as potential Lassa immunotherapeutics was facilitated by structural studies and mutational analyses that identified protective epitopes on the prefusion form of the LASV glycoprotein. Human mAbs were screened for reactivity to different neutralizing epitopes, potency, and broad reactivity against multiple lineages of LASV. MAbs were downselected in a guinea pig model of Lassa fever. A cocktail of three human MAbs designated Arevirumab-3 rescued 100% of Cynomolgus macaques at advanced stages of disease more than a week post-infection. Antibody therapeutics may be further developed in clinical trials in endemic areas potentially offering a key treatment option for Lassa fever.

Genotyping for IL28B, HLA-C, and KIR genes improves prediction of HCV treatment response. These findings support a role for natural killer (NK) cell activation in PegIFN/R treatment-induced clearance, partially mediated by IL28B.
Inhibition of Mitogen-Elicited Signal Transduction and Growth in Prostate Cancer with a Small Peptide Derived from the Functional Domain of DOC-2/DAB2 Delivered by a Unique Vehicle (2006)

Differentially expressed in ovarian cancer-2/disabled 2 (DOC-2/DAB2) protein, often lost in prostate cancer and other cancer types, is a part of homeostatic machinery in normal prostate epithelium. DOC-2/DAB2 modulates mitogen-elicited mitogen-activated protein kinase (MAPK) signal transduction by sequestering several adaptor or effector molecules, such as growth factor receptor bound protein 2 and c-Src. We have shown that the proline-rich sequence in DOC-2/DAB2 is the key functional domain for this action. In this study, we further synthesized peptide based on the functional proline-rich domain and examined its biological function in prostate cancer using cell-permeable peptide (CPP) as a delivery system. From screening of several CPPs in prostate cancer cell lines, a polyarginine peptide (R11) seemed to be the best delivery vehicle because of its highly efficient uptake. In addition, we also observed a similar in vitro half-life and cellular location of R11 in four different prostate cancer cell lines. By conjugating a proline-rich sequence (PPL) or control sequence (AAL) derived from DOC-2/DAB2 to the COOH terminus of R11, we showed that R11PPL but not R11 or R11AAL was able to suppress either serum- or androgen-induced cell proliferation in prostate cancer cells without endogenous DOC-2/DAB2 expression. Consistently, the activation status of MAPK elicited by these mitogens was significantly inhibited by R11PPL but not by R11AAL or R11. Taken together, we conclude that a functional peptide derived from proline-rich domain in DOC-2/DAB2 has growth-inhibitory activity as its native protein, and CPP seems to be an efficient delivery system in prostate cancer cells.
A 150Mbit/s 3GPP LTE turbo code decoder (2010)

3GPP long term evolution (LTE) enhances the wireless communication standards UMTS and HSDPA towards higher throughput. A throughput of 150 Mbit/s is specified for LTE using 2×2 MIMO. For this, highly punctured Turbo codes with rates up to 0.95 are used for channel coding, which is a big challenge for decoder design. This paper investigates efficient decoder architectures for highly punctured LTE Turbo codes. We present a 150 Mbit/s 3GPP LTE Turbo code decoder, which is part of an industrial SDR multi-standard baseband processor chip.
N-Heterocyclic carbene metal complexes in medicinal chemistry (2012)

Metal complexes with N-heterocyclic carbene (NHC) ligands are widely used in chemistry due to their catalytic properties and applied for olefin metathesis among other reactions. The enhanced application of this type of organometallics has over the last few years also triggered a steadily increasing number of studies in the fields of medicinal chemistry, which take advantage of the fascinating chemical properties of these complexes. In fact it has been demonstrated that metal NHC complexes can be used to develop highly efficient metal based drugs with possible applications in the treatment of cancer or infectious diseases. Complexes of silver and gold have been biologically evaluated most frequently but also platinum or other transition metals have demonstrated promising biological properties.
Inhibition of Indoleamine-2,3-dioxygenase (IDO) in Glioblastoma Cells by Oncolytic Herpes Simplex Virus (2012)

Successful oncolytic virus treatment of malignant glioblastoma multiforme depends on widespread tumor-specific lytic virus replication and escape from mitigating innate immune responses to infection. Here we characterize a new HSV vector, JD0G, that is deleted for ICP0 and the joint sequences separating the unique long and short elements of the viral genome. We observed that JD0G replication was enhanced in certain glioblastoma cell lines compared to HEL cells, suggesting that a vector backbone deleted for ICP0 may be useful for treatment of glioblastoma. The innate immune response to virus infection can potentially impede oncolytic vector replication in human tumors. Indoleamine-2,3-dioxygenase (IDO) is expressed in response to interferon γ (IFNγ) and has been linked to both antiviral functions and to the immune escape of tumor cells. We observed that IFNγ treatment of human glioblastoma cells induced the expression of IDO and that this expression was quelled by infection with both wild-type and JD0G viruses. The role of IDO in inhibiting virus replication and the connection of this protein to the escape of tumor cells from immune surveillance suggest that IDO downregulation by HSV infection may enhance the oncolytic activity of vectors such as JD0G.
