Quasi-static method for predicting link-level performance (2003)

In this paper, we investigate the performance of a quasi-static method used to predict link-level error performance in dynamic system simulations. Two flavors of the quasi-static approach are used to model the link characteristics: (a) static curves with fudge factors; and (b) short-term frame error curves. For the fudge factor based method, we examine the various factors (or penalties) required for the method to work properly, their limitations in capturing the various features of the high-speed packet data channel, and their effects on the overall accuracy of the technique. Here, we concentrate on three important penalties: puncturing penalty, Doppler penalty, and demapping penalty. The quasistatic method based on short-term frame error curves is used to generate frame erasures for voice and control channels associated with high-speed packet data channels. From simulation results, it is shown that both variations of the quasi-static method can provide accurate prediction of link-level performance at certain operating ranges, provided that the penalties are correctly obtained. At low frame error rates and moderate to high speeds, however, the quasi-static method often fails to accurately reflect frame error performance at the link level.
Ocular Changes in TgF344-AD Rat Model of Alzheimer's Disease (2014)

In this study, we observed pathological changes in the choroid and in RPE cells in the TgF344-AD rat model; choroidal thinning was observed further in human AD retina. Along with Ab deposition, the inflammatory response was manifested by microglial recruitment and complement activation. Further studies are needed to elucidate the significance and mechanisms of these pathological changes [corrected].
End-Cap Effects on Vibrational Structures of Finite-Length Carbon Nanotubes (2005)

Vibrational structures of C60-related finite-length nanotubes, C(40+20n) and C(42+18n) (1 < or = n < or = 4), in which n is, respectively, the number of cyclic cis- and trans-polyene chains inserted between fullerene hemispheres, are analyzed from density functional theory (DFT) calculations. To illuminate the end-cap effects on their vibrational structures, the corresponding tubes terminated by H atoms C(20n)H20 and C(18n)H18 (1 < or = n < or = 5) are also investigated. DFT calculations show a broad range of vibrational frequencies for the finite-size nanotubes: high-frequency modes (1100-1600 cm(-1)) containing oscillations along tangential directions (tangential modes), medium-frequency modes (700-850 cm(-1)) whose oscillations are located on the edges or end caps, and low-frequency modes (300-600 cm(-1)) involving oscillations along the radial directions (radial modes). Broadening of the calculated frequencies is due to the number of nodes in the standing waves of normal modes in the finite-size tubes. In the capped tubes, calculated vibrational frequencies are insensitive to the number of chains (n), whereas in the uncapped tubes, most vibrational frequencies change significantly with an increase in tube length. The discrepancy in the size dependency is reasonably understood by their C-C bonding networks; the capped tubes have similar bond-length alternation patterns within the polyene chains irrespective of n, whereas the uncapped tubes have various bond-deformation patterns. Thus, DFT calculations illuminate that the edge effects have strong impacts on the vibrational frequencies in the finite-size nanotubes.

IKCa1 is an immediate early response gene mediating coronary smooth muscle phenotypic modulation (2006)

We previously demonstrated functional upregulation of intermediate-conductance Ca2+-activated K+ channel (IKCa1) with the development of early coronary atherosclerosis in vivo and as a prerequisite for platelet-derived growth factor BB (PDGF-BB) induced porcine coronary smooth muscle cell (CSMC) dedifferentiation and migration in vitro. Our objective was to examine the temporal regulation of IKCa1 and smooth muscle marker gene expression in porcine CSMC exposed to coronary balloon injury (CBI) in vivo or PDGF-BB in vitro. Two hours following CBI, laser capture microdissection of media from injured vessels demonstrated higher IKCa1, c-jun, and c-fos, but unaltered amounts of SMMHC mRNA compared to control media. PDGF-BB increased enrichment of H4 acetylation and c-jun to the AP-1 binding site of the IKCa1 promoter ~4-fold, an effect blocked by TRAM-34, a specific IKCa1 channel blocker. PDGF-BB increased IKCa1 and decreased myocardin mRNA at 30 minutes, but did not decrease smooth muscle myosin heavy chain (SMMHC) or smoothelin expression until 10 hours. In conclusion, these data indicate that AP-1 dependent upregulation of IKCa1 is an immediate and requisite factor initiating smooth muscle specific gene suppression, i.e. CSMC phenotypic modulation, during coronary injury.

On Full-Duplex Radios With Modulo-ADCs (2021)

Wireless full-duplex (FD) transceivers have become more commonplace in the recent years, enabled by improvements in hardware as well as in signal processing algorithms dedicated to self-interference (SI) mitigation. A key design target for any FD radio is to limit the analog-to-digital converter (ADC) quantization noise affecting the signal of interest (SoI), which results from the difference in dynamic range between the SI and the SoI at the input of the ADC. Indeed, when using conventional ADCs, since the SI power is much larger than that of the SoI, the SI spans most of the ADC's dynamic range and the SoI becomes distorted by a large quantization noise. Reducing the power of the SI before the ADC, for example via analog domain SI cancellation, is so far the only means to mitigate this undesired effect. In this paper we consider the use of so-called modulo ADCs as a new tool to reduce the quantization noise that affects the SoI in the presence of SI. We demonstrate theoretically and numerically that by substituting the conventional ADCs with modulo-ADCs, which fold the analog input signal before analog-to-digital conversion, and by using appropriately designed analog gain control and digital-domain SI cancellation, one can reduce the quantization noise that affects the SoI. As such, the work in this paper provides a new technique for counteracting the detrimental effect of SI in analog-to-digital conversion and, thus, provides a new route to be explored in order to enhance the performance of FD radios.
Tracking Data Flow at Gate-Level through Structural Checking (2016)

The rapid growth of Internet-of-things and other electronic devices make a huge impact on how and where data travel. The confidential data (e.g., personal data, financial information) that travel through unreliable channels can be exposed to attackers. In hardware, the confidential data such as secret cipher keys are facing the same issue. This problem is even more serious when the IP is from a 3rd party and contains scan-chains. Thus, data flow tracking is important to analyze possible leakage channels in fighting against such hardware security threats. This paper introduces a method for tracking data flow and detecting potential hardware Trojans in gate-level soft IPs using assets and Structural Checking tool.
ARP and QPP Interleavers for LTE Turbo Coding (2008)

The Long Term Evolution (LTE) of the WCDMA standard requires turbo decoding throughputs of up to 100 Mbps. Unfortunately, the existing WCDMA turbo interleaver does not permit an efficient high throughput implementation. The almost regular permutation (ARP) and quadratic polynomial permutation (QPP) interleavers were proposed to rectify this situation with QPP selected for LTE. In this paper, the interleavers are compared and a full suite of LTE designs and performance results for both are presented.
Robust multi-level phase shift modulation in high-speed WDM transmission (2005)

In this paper, an overview of promising solutions for multi-level modulation formats, primarily based on phase shift keying (PSK), in optical WDM-transmission is presented and some recent results are summarized. With PSK modulation the option of multi-level signalling is offered which means that more than one bit is mapped on one transmitted symbol and thus offering bandwidth reduction for increased spectral efficiency. We investigate the performance with respect to receiver sensitivity, non-linear fibre impairments, chromatic and polarization mode dispersion. Last but not least the implementation-effort at high speed must comply with economic constraints.
A metal-free, full-color stacked organic light-emitting device (1999)

We report the demonstration of a transparent, completely metal-free, full-color stacked organic light-emitting device (SOLED). The SOLED emits light from both top and bottom (substrate) surfaces with total external quantum efficiencies of 0.65%, 1.3%, and 2.2% for the green, blue, and red stacked subpixels, respectively. The respective top emission quantum efficiencies for the three subpixels are 0.23%, 0.63%, and 1.6%. The angular dependence of emission colors due to microcavity effects is weak when viewed from the top device surface. This metal-free SOLED is from 21% to 50% transparent over the entire visible spectral range. Capability for top emission makes this device suitable for integration with electronic components in active matrix display backplanes.
Discretization of Boundary Integral Equations by Differential Forms on Dual Grids (2004)

In this paper, some integral equations of electromagnetics are reformulated in terms of differential forms. The integral kernels become double forms. These are forms in one space with coefficients that are forms in another space. The results correspond closely to the usual treatment, but are clearer and more intuitive. Since differential forms possess discrete counterparts, the discrete differential forms, such schemes lend themselves naturally to discretization. As an example, a boundary integral equation for the double curl operator is considered. The discretization scheme generalizes the well-known collocation technique by using de Rham maps. Depending on the integral operator to be discretized, the 1-form valued residual is forced to be zero either over the 1-chains of the primal or the dual grid.
An Efficient, Scaleable Procedure for the Conversion of Esters to Isoxazoles (1997)

A concise, regiocontrolled route to isoxazoles, based on the condensation of an ester with a metallated imine, has been developed. The intermediate vinylogous amides react smoothly with hydroxylamine to provide, after dehydration, substituted isoxazoles. The method has been used for the multi-kilo scale preparation of ABT-418, a novel cholinergic channel activator.
Identification of the Perosamine Synthetase Gene ofBrucella melitensis16M and Involvement of Lipopolysaccharide O Side Chain inBrucellaSurvival in Mice and in Macrophages (1998)

Brucella organisms are facultative intracellular bacteria that may infect many species of animals as well as humans. The smooth lipopolysaccharide (S-LPS) has been reported to be an important virulence factor of these organisms, but the genetic basis of expression of the S-LPS O antigen has not yet been described. Likewise, the role of the O side chain of S-LPS in the survival of Brucella has not been clearly defined. A mini-Tn5 transposon mutant library of Brucella melitensis 16M was screened by enzyme-linked immunosorbent assay (ELISA) with monoclonal antibodies (MAbs) directed against the O side chain of Brucella. One mutant, designated B3B2, failed to express any O side chain as confirmed by ELISA, Western blot analysis, and colony coloration with crystal violet. Nucleotide sequence analysis demonstrated that the transposon disrupted an open reading frame with significant homology to the putative perosamine synthetase genes of Vibrio cholerae O1 and Escherichia coli O157:H7. The low G+C content of this DNA region suggests that this gene may have originated from a species other than a Brucella sp. The survival of B. melitensis mutant strain B3B2 in the mouse model and in bovine macrophages was examined. The results suggested that S-LPS or, more precisely, its O side chain is essential for survival in mice but not in macrophages.
Perfect Tracking Control System with Prediction State Observer for Next-Generation Optical Disks (2011)

Recently, the capacity of optical disk recording systems has been increasing. Optical disk drive systems must realize high-precision tracking control. For this purpose, we previously proposed a tracking control system that is composed of both a robust feedback controller and a zero-phase-error feedforward tracking controller. The proposed feedforward tracking control system effectively suppresses the tracking error caused by track eccentricity. However, it is sometimes difficult for conventional feedforward tracking control systems to realize higher precision in their tracking control. Hence, in this paper we propose a new perfect tracking control (PTC) system with a prediction state observer for next-generation optical disks. The experimental results confirm that the proposed system suppresses the tracking error at a disk rotation speed of 8000 rpm. Therefore, the proposed system realizes high-precision tracking control.
Statistical Retardation Delay of I-MOS and Its Measurement Using TDR (2010)

In this letter, we study the statistical retardation delay of the impact ionization MOSFET (I-MOS) that is observed during the turn-on transient. Since seed carriers are required to initiate an avalanche breakdown in the I-MOS, the turn-on delay of the I-MOS has an additional random component associated with the generation of seed carriers. The characteristics of this delay are statistically analyzed and measured for the first time with time-domain reflectometry. The results show a fundamental limitation of the I-MOS delay, which is directly associated with the leakage current.
Adaptive channel tracking and bit-power reallocation for 100Gb/s uncooled DMT transceiver (2014)

The DMT channel condition may change in the uncooled transceivers. Based on proposed channel tracking and bit-power reallocation, the BER limitation is always satisfied in the single lane 116Gb/s transmission over 10km SSMF when the temperature changes 50 °C.
A line code with quick-resynchronization capability and low latency for the optical data links of LHC experiments (2014)

We propose a line code that has fast resynchronization capability and low latency. Both the encoder and decoder have been implemented in FPGAs. The encoder has also been implemented in an ASIC. The latency of the whole optical link (not including the optical fiber) is estimated to be less than 73.9 ns. In the case of radiation-induced link synchronization loss, the decoder can recover the synchronization in 25 ns. The line code will be used in the ATLAS liquid argon calorimeter Phase-I trigger upgrade and can also be potentially used in other LHC experiments.
Rotor Position Estimation of AC Machines Using the Zero-Sequence Carrier-Signal Voltage (2005)

This paper analyzes the sensorless control of ac machines based on the zero-sequence voltage generated by the injection of a carrier-signal voltage. The analysis focuses on rotor position estimation (tracking of rotor-position-dependent saliencies), but the methods discussed apply equally to flux position estimation (tracking of flux-dependent saliencies). Analyses of relevant aspects like selection of the carrier-signal frequency, measurement of the zero-sequence carrier-signal voltage, and decoupling of saturation-induced saliencies are included.

NUFIP1 is a ribosome receptor for starvation-induced ribophagy (2018)

The lysosome degrades and recycles macromolecules, signals to the master growth regulator mTORC1 [mechanistic target of rapamycin (mTOR) complex 1], and is associated with human disease. We performed quantitative proteomic analyses of rapidly isolated lysosomes and found that nutrient levels and mTOR dynamically modulate the lysosomal proteome. Upon mTORC1 inhibition, NUFIP1 (nuclear fragile X mental retardation-interacting protein 1) redistributes from the nucleus to autophagosomes and lysosomes. Upon these conditions, NUFIP1 interacts with ribosomes and delivers them to autophagosomes by directly binding to microtubule-associated proteins 1A/1B light chain 3B (LC3B). The starvation-induced degradation of ribosomes via autophagy (ribophagy) depends on the capacity of NUFIP1 to bind LC3B and promotes cell survival. We propose that NUFIP1 is a receptor for the selective autophagy of ribosomes.
Development of a compact DC magnetometer using HTS-SQUID and a rotating sample (2012)

We developed a compact DC magnetometer using a high-temperature superconductor (HTS) superconducting quantum interference device (SQUID) to measure very weak magnetic signals from samples such as paramagnetic and diamagnetic materials. The samples were rotated in the DC magnetic field that was detected by a normal conductive pick-up coil. The detected signal was transferred to an input coil that was inductively coupled to the SQUID. To clarify the basic characteristics of this system, the magnetic signal from a magnetic material was measured by varying the sample position and rotation speed. Then, the magnetic signal from pure water was measured under the optimized condition and a very weak magnetic signal from pure water was successfully detected. Therefore, the developed system could be applied to various non-destructive evaluation systems.
Impact of the annexin 1 system on focal cerebral ischaemia‐reperfusion injury in mice (2006)

Stroke is a leading cause of death worldwide. We have addressed the role of exogenous and endogenous annexin 1 (AnxA1) in murine focal ischaemia, with intravital microscopy. Littermate wildtype (WT) and AnxA1 null mice were subjected to middle cerebral artery occlusion for 1 h and 24 h reperfusion. Neurological deficit, infarct volume and leukocyte‐endothelial cell interactions (LEI) were determined. Results: Ischaemia‐reperfusion increased LEI in both WT and AnxA1 null mice. Adherent leukocytes were increased in comparison to sham counterparts in both WT (472±77 vs. 0 cells) and AnxA1 null mice (728±113 vs.33±33 cells). Human recombinant AnxA1 (1 μg dose, given 0, 6, and 18 h, 28 nmol/mouse) restored WT phenotype in ANXA1 null mice. Given 3 times, peptide Ac2‐26 (100 μg or 33 nmol) inhibited infarct volume (33±2% vs. 45±6% in vehicle animals). This protective effect was mirrored by reduced leukocyte adhesion, compared to vehicle animals. The formyl peptide receptor (FPR) antagonist Boc2, prevented the inhibitory effect of peptide Ac2–26. Conclusions: Endogenous AnxA1 exerts a tonic inhibitory role on cerebral vessel reactivity post‐reperfusion. Pharmacologically, an AnxA1‐derived peptide exerted protective actions by activating a receptor of the FPR family. These findings might be of potential interest for the development of new therapeutics for stroke.

Bimaterial Microcantilevers as a Hybrid Sensing Platform (2008)

Abstract Microcantilevers, one of the most common MEMS structures, have been introduced as a novel sensing paradigm nearly a decade ago. Ever since, the technology has emerged to find important applications in chemical, biological and physical sensing areas. Today the technology stands at the verge of providing the next generation of sophisticated sensors (such as artificial nose, artificial tongue) with extremely high sensitivity and miniature size. The article provides an overview of the modes of detection, theory behind the transduction mechanisms, materials employed as active layers, and some of the important applications. Emphasizing the material design aspects, the review underscores the most important findings, current trends, key challenges and future directions of the microcantilever based sensor technology.
The performance of multi-carrier CDMA in cellular overlay systems (2003)

The idea of multi-carrier code-division multiple-access (CDMA) has recently received significant attention as an alternative to traditional single-carrier CDMA. In this paper multi-carrier CDMA is applied to a cellular overlay scenario which uses a fading channel model. It is shown that the diversity advantage realized with the use of multi-carrier CDMA allows the CDMA users to lower their transmitted powers, and the benefits to the narrowband system are substantial.
3D simulations of ultra-small MOSFETs: the role of the discrete impurities on the device terminal characteristics (2002)

We have developed a three-dimensional particle-based simulator with a real-space molecular dynamics routine that avoids the "double-counting" of the long-range portion of the Coulomb force. Our Monte Carlo simulator can accurately model high field transport in semiconductor devices, while enabling the real-space treatment of the interactions, including multi-ion and multi-electron contributions, through the coupled molecular dynamics scheme. It has already been shown that the inclusion of the electron-electron and electron-ion interactions plays important role in device simulations. Here, we investigate how the atomistic description of the dopant ions in the channel affect the threshold voltage and drift velocity in devices representative of the state-of-the-art technology that have different number and different distribution of the impurity atoms in their active region.
A Light Signalling Approach to Node Grouping for Massive MIMO IoT Networks (2020)

Massive MIMO is a leading technology to connect very large numbers of energy constrained nodes, as it offers both extensive spatial multiplexing and large array gain. A challenge resides in partitioning the many nodes into groups that can communicate simultaneously such that the mutual interference is minimized. We here propose node partitioning strategies that do not require full channel state information, but rather are based on nodes' respective directional channel properties. In our considered scenarios, these typically have a time constant that is far larger than the coherence time of the channel. We developed both an optimal and an approximation algorithm to partition users based on directional channel properties, and evaluated them numerically. Our results show that both algorithms, despite using only these directional channel properties, achieve similar performance in terms of the minimum signal-to-interference-plus-noise ratio for any user, compared with a reference method using full channel knowledge. In particular, we demonstrate that grouping nodes with related directional properties is to be avoided. We hence realise a simple partitioning method requiring minimal information to be collected from the nodes, and where this information typically remains stable over a long term, thus promoting their autonomy and energy efficiency.
