Enhanced Device Stability of Ionic Gating Molybdenum Disulfide Transistors (2019)

The application of ion gels as gate dielectrics having an excellent mechanical flexibility and high capacitance to molybdenum disulfide (MoS 2 ) devices has been extensively studied; however, some issues remain unaddressed with regard to device stability such as gate leakage current, hysteresis, and bias stress instability. This study suggests a fabrication process for the ionic gating of the MoS 2 device to enhance the device stability by laminating the ion gel film onto the MoS 2 transistor using a cut‐and‐stick method and adding a passivation layer to remove unintentional parasitic capacitances generated by the capacitive coupling effect. The ionic gating MoS 2 transistor fabricated via this process operates at a low voltage (&lt;1 V) and exhibits superior electrical characteristics such as low gate leakage currents (≈10 −11 A), high on–off ratio (&gt;10 6 ), and low hysteresis (&lt;0.05 V). To further investigate the device stability, bias stress instability of the ionic gating MoS 2 transistor is examined. The charge‐trapping mechanism is the main cause of threshold voltage shifts under gate bias stress.
Urban regeneration and neo-liberal state reform: changing roles of cities in the Japanese developmental state (2013)

Since the late 1970s urban regeneration has become a powerful catchword associated with processes of neo-liberalization, post-modernization and globalization in a context of increasingly immaterialized capitalism. In Europe and most notably in continental Europe, the advent of the European Union has intersected with the aforementioned structural processes at the global scale. The resulting experiences of urban regeneration in Europe reflect the intermingling of European models of urban governance with broader processes of globalization and neo-liberalization. As a result, the term urban regeneration in continental Europe appears to be rather indeterminate in its outcomes compared with the Anglo-American context in which this and related terms were originally coined. The chapter develops this argument by using the illustrative cases of the regeneration processes in central areas of Turin and Naples, two large cities in Italy located in the prosperous North and the less advantaged South, respectively.
Non-data aided joint estimation of carrier frequency offset and channel using periodic modulation precoders: performance analysis (1999)

Previous results have shown that blind channel estimators, which are robust to the location of channel zeros and channel order overestimation errors, can be derived for communication channels equipped with transmitted induced cyclostationarity (TIC) precoders. This paper addresses the problem of joint estimation of the unknown intersymbol interference (ISI) and carrier frequency offset using TIC-based set-ups. First, it is shown that the second-order cyclic statistics of the output allow recovery of the channel taps under a scaling factor ambiguity dependent on the unknown carrier offset frequency. Next, a carrier frequency estimator is proposed, and its asymptotic (large sample) performance is analyzed. It is shown that the asymptotic performance of the frequency estimator improves in the presence of a channel equalizer for high SNRs. Finally, numerical simulations are presented to collaborate the performance of proposed algorithms.
Blood Bag Plasticizers Influence Red Blood Cell Vesiculation Rate without Altering the Lipid Composition of the Vesicles (2015)

Membrane stabilization capacity differed among the plasticizers. RBC in BTHC bags stored more poorly, while DEHP and DINCH bags offered better protection against vesiculation, osmotic stress, and Hb loss.
Resolving impact of technical and biological variability on the convolutional neural networks: evaluating chest x-ray scans (2023)

Large chest x-ray datasets accumulate technical and biological variations. Technical variations are often caused by differences in scanner types (e.g. x-ray energy) whereas biological variations refer to those resulting from morphological differences among populations. Such variations decrease the generalizability of convolutional neural networks (CNNs) and could lead to disparities within specific patient subgroups. We sought to disentangle the sources of variations for a CNN in the context of technical and biological variability. The primary goal of this study was to understand whether tailored and specific AI models might need to be created (i.e., gender-specific or machine-specific AI models).
Whither the Emerging Markets' Currencies? (2001)

The authors look into the fiscal and monetary options available to the governments of emerging countries to manage both their economies and their currencies. Having first observed that Argentina9s government has struggled to sell its T-bills to a largely captive domestic debt market, that the Brazilian real is down more than 20% since January, and that, in the rest of the world, there is doubt about Asia9s economic prospects and Turkey9s commitment to reform, they suggest that, taken together, these events raise the prospect of financial contagion spreading across the emerging markets and that the root of many problems can be traced to the organization of these countries9 monetary system. Describing and evaluating the consequences of currency policies centered on devaluation, pegging the home currency to an external yardstick or to currency boards, they offer an intriguing analysis concluding that emerging markets would avoid the speculative attacks related to capital outflows if they did not have a central bank and adopted some other country9s monetary policy.
Hydrostatic Compression Effects on Fifth-Group Element Superconductors V, Nb, and Ta Subjected to High-Pressure Torsion (2019)

In fifth-group element superconductors V, Nb, and Ta, the increase in superconducting transition temperature (Tc) was attempted by using both high-pressure torsion (HPT) and additional hydrostatic pressure (HP) compression. The former brings about the grain refinement and strain accumulation in the unit-cell level. The additional compression for severely strained superconductors triggers strengthening intergrain-contact and/or structural deformation in the unit-cell level. The manner of the appearance of the above two effects depends on the kind of elements: First, in V, there is no prominent effect of HPT, comparing to the hydrostatic compression effects on its non-strained material. Next, in Ta, the effect of strengthening intergrain-contact appears at small hydrostatic compression, resulting in temporal increase in Tc. Finally, Nb exhibits prominent increase in Tc by both effects and, in particular, the structural deformation in the unit-cell level promotes the increase in Tc. Thus, the accumulation of residual strain in the level of starting material can be a promising work to manipulate Tc under HP compression.
The Asian Citrus Psyllid Genome (Diaphorina citri, Hemiptera) (2014)

The Asian citrus psyllid, Diaphorina citri (Hemiptera), is an important pest of citrus because it vectors bacteria responsible for huanglongbing, which is one of the most serious diseases of citrus worldwide.&nbsp; The first genome draft of D. citri (DIACI_1.0) was completed in 2011 (ARS, Ft. Pierce, FL), however, gaps in the assembly prompted additional sequencing using the long run PacBio system at the Los Alamos National Lab, NM.&nbsp; The revised draft genome (DIACI_1.1) was assembled using the new software PB-Jelly, with an improved N50 of 38 kb (up from 25 kb) and an increase by over 10 million in the number of resolved bases.&nbsp; The genome and transcriptome have been submitted into the public domain at the National Center for Biotechnology Information, NCBI, and the genome is currently being submitted to be processed and made available for access by the larger research community [http://www.ncbi.nlm.nih.gov/genome?LinkName=bioproject_genome&amp;from_uid=29447].&nbsp; The psyllid transcriptome identified over 25,600 predicted genes, and is supported by an additional 19,598 previous EST’s.&nbsp; Life-stage specific transcripts were identified for adults, nymphs and eggs.&nbsp; BlastX analyses showed that the psyllid genome has the most similarity to the Pea Aphid, Acyrthosiphon pisum, another hemipteran.&nbsp; The transcriptome data was provided to the Innocentive® Challenge Program in 2011 to advance efforts for RNAi development against psyllids.&nbsp; Other researchers are also using these data to develop strategies to suppress psyllid populations.&nbsp; Efforts are now focused on annotation of the psyllid genome which will provide more information on the genetic basis of psyllid biology.&nbsp; Free Downloads of the most recent datasets can be found at: http://www.psyllid.org/node/10 which includes the&nbsp;transcriptome and predicted protein files in FASTA format, and the gene locations on the DIACI_1.1 Genome assembly (GFF3 format).
Intrinsic carrier mobility in amorphous In–Ga–Zn–O thin-film transistors determined by combined field-effect technique (2010)

Amorphous In–Ga–Zn–O (α-IGZO) is expected for thin-film transistors (TFTs) in next-generation flat-panel displays but its intrinsic properties are not understood well and different mobility models have been applied to different films. This letter reports that a universal mobility model is obtained using a field-effect technique and capacitance-voltage method. Electrical characteristics of α-IGZO TFTs subjected to different annealing are reproduced using the mobility model and different trap densities. The present achievement will be a necessary basis to establish device and circuit simulators for α-IGZO-based electronic applications.
Sensing Data Management System Using LoRa Based on Mobius Platform (2019)

사물 인터넷 서비스를 실현하기 위해서는 확장성을 고려한 센싱 데이터 관리 및 서비스 구축이 필요하다. 그러나 기존 사물인터넷 서비스들은 서비스 업체별로 고유한 프로토콜 및 표준화되지 않은 기능들을 사용하며, 블루투스 등의 단거리 통신 기술을 사용하므로 데이터 관리 및 서비스 제공에 어려움이 따른다. 또한 광역 통신망을 구축하기 위해서는 다수의 AP나 게이트웨이들을 포함하여야한다. 본 논문에서는 모비우스 플랫폼을 기반으로 로라(LoRa, Long Range) 통신을 이용한 센싱 데이터 관리 시스템에 관한 연구를 수행하고자한다. Tas를 구동하는 엔드 디바이스를 구성하여 센싱 데이터를 수집하고, &Cube를 구동하는 응용 게이트웨이를 구성하여 센싱 데이터를 서버로 송신한다. 또한 모비우스를 구동하는 관리 서버를 구성하여 응용 게이트웨이로부터 송신 받은 센싱 데이터를 관리하여 모니터링 서비스를 제공한다. 엔드 디바이스와 게이트웨이 간의 로라 통신을 통하여 광역 통신망을 구축하고 모비우스 플랫폼을 통하여 사물 인터넷에 부합하는 데이터 관리 및 서비스를 제공하고자 한다.In order to realize IoT(Internet of Things) service, it is necessary to manage sensing data and build a service with respect to its scalability. However, existing internet services use unique protocols and non-standardized functions for each service provider, and it is difficult to provide data management and service because they use short-range communication technology such as Bluetooth. In addition, plurality of APs and gateways must be taken into consideration in establishing a wide area network. In this paper, we propose a sensing data management system using LoRa(Long Range) communication based on Mobius platform. The end device that drives Tas is configured to collect sensing data, configure an application gateway that drives &Cube, and transmit sensing data to the server. In addition, a server that manages the Mobius is configured to handle the sensing data transmitted from the application gateway to provide a monitoring service. We establish a wide area network through LoRa communication between the end device and the gateway and provide data management and service corresponding to the internet through the Mobius platform.

We demonstrate a method to generate ultra-high-speed phase correlated optical signals using a Kerr shutter. Two examples are provided: 160-Gb/s CSRZ with pair-wise alternating phase, and 320-Gb/s CSRZ signals. We also discuss other phase correlated data signals including RZ-VSB, DPSK, and CSRZ with alternating phases in groups.
A new concept for microwave MCMs (2002)

The drive in the industry towards smaller, lighter, more efficient products encompasses all types of products, including microwave communication. At Ericsson Microwave Systems, customer demand for a product which integrates the microwave control unit with the antenna in the mast has been noted. This means that the indoor control units become redundant and there is less hardware. This packaging concept is based on the fact that the electronics are placed behind the flat antenna unit for efficient use of the available area. The technical concept is a multilayer PTFE thermoplastic motherboard design and split-function MCMs with possibilities for buried capacitors etc. The chip environment is split between the MCM and the motherboard. The motherboard has shielded conductors and a common ground plane with the MCM. The chips are placed level with the substrate to which they are connected with bond wires, and therefore the wires can be made shorter than if the chips were placed on the board as in ordinary chip and wire cases. The reduced wire length is most significant in order to achieve good electrical performance. To meet market demand, we have designed an electronics packaging system for multi-frequency purposes, for products ranging from 5-40 GHz. Current antenna integrated electronics are mostly military applications designed in exclusive materials for advanced production methods. On entering a market for commercial applications, new methods must be implemented to reach cost-effective targets. This paper presents some possible methods for reaching this goal.
Voltage Stress Modeling and Measurement for Random-Wound Machine Windings Driven by Inverters (2020)

This article studies the voltage stress in random-wound machine windings under steep-fronted voltage excitations from inverter drives. The voltage stress in this article includes overshooting voltages between any two conductors in the windings, and overshooting voltages between individual conductors and the stator ground wall. This stress may accelerate insulation degradation in inverter-fed machines compared to traditional AC machines. A high-fidelity finite element (FE) model was used to analyze individual conductors of random-wound windings and predict the voltage stress during switching transients. Experimental validation of the model was conducted using a purpose-made random-wound three-phase winding, designed to allow access to multiple coils and parallel strands. Firstly, the voltage propagation and the voltage stress for both single-phase and three-phase windings were simulated and tested under Pulse Width Modulation (PWM) voltage excitations without a rotor. Both voltage propagations among all the coils and individual turns were measured and compared with simulated results. The voltage stress on each part of the machine stator winding insulation system was tested and studied. Then, similar simulations and tests were conducted with a demagnetized rotor installed to study how the rotor saliency affects the voltage propagation and voltage stress. The measured winding voltage propagations for all scenarios generally agree with the FE simulated results.
Discrimination of GLUTs by Fructose Isomers Enables Simultaneous Screening of GLUT5 and GLUT2 Activity in Live Cells (2023)

Facilitative carbohydrate transporters (GLUTs, SLC2 gene family) are transmembrane proteins transporting hexoses and other sugars based on cellular metabolic demands. While a direct link between GLUTs and metabolic disorders has framed them as important biological and medicinal targets, targeting disease-relevant GLUTs remains challenging. In this study, we aimed to identify substrate-GLUT interactions that would discriminate between major fructose transporters. We examined the uptake distribution for conformational and configurational isomers of fructose using the corresponding conformationally locked fluorescently labeled mimetics as probes for assessing GLUT preferences in real time. Through comparative analysis of the uptake of the probes in the yeast-based single GLUT expression systems and the multi-GLUT mammalian cell environment, we established the ability of fructose transporters to discriminate between fructose conformers and epimers. We demonstrated that recreating the conformational and configurational mixture of fructose with molecular probes allows for the specific probe distribution, with fructofuranose mimetic being taken up preferentially through GLUT5 and β-d-fructopyranose mimetic passing through GLUT2. The uptake of α-d-fructopyranose mimetic was found to be independent of GLUT5 or GLUT2. The results of this study provide a new approach to analyzing GLUT5 and GLUT2 activity in live cells, and the findings can be used as a proof-of-concept for multi-GLUT activity screening in live cells. The research also provides new knowledge on substrate-GLUT interactions and new tools for monitoring alterations in GLUT activities.
99% efficient three-phase buck-type SiC MOSFET PFC rectifier minimizing life cycle cost in DC data centers (2016)

Due to the increasing power consumption of data centers, efficient dc power distribution systems have become an important topic in research and industry over the last years. Furthermore the power consumed by data centers is an economic factor, which implies that all parts of the distribution system should be designed to minimize the life cycle cost, i.e. the sum of first cost and the cost of dissipation. This paper analyzes a three-phase buck-type PFC rectifier with integrated active 3 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rd</sup> harmonic current injection for dc distribution systems.

Precoding in Multiple-Antenna Broadcast Systems with a Probabilistic Viewpoint (2007)

In this paper, we investigate the minimum average transmit energy that can be obtained in multiple antenna broadcast systems with channel inversion technique. The achievable gain can be significantly higher than the conventional gains that are mentioned in methods like perturbation technique of Peel, et al. In order to obtain this gain, we introduce a Selective Mapping (SLM) technique (based on random coding arguments). We propose to implement the SLM method by using nested lattice codes in a trellis precoding framework.
Development of NIST standard reference material 2373: Genomic DNA standards for HER2 measurements (2016)

NIST standard reference material (SRM) 2373 was developed to improve the measurements of the HER2 gene amplification in DNA samples. SRM 2373 consists of genomic DNA extracted from five breast cancer cell lines with different amounts of amplification of the HER2 gene. The five components are derived from the human cell lines SK-BR-3, MDA-MB-231, MDA-MB-361, MDA-MB-453, and BT-474. The certified values are the ratios of the HER2 gene copy numbers to the copy numbers of selected reference genes DCK, EIF5B, RPS27A, and PMM1. The ratios were measured using quantitative polymerase chain reaction and digital PCR, methods that gave similar ratios. The five components of SRM 2373 have certified HER2 amplification ratios that range from 1.3 to 17.7. The stability and homogeneity of the reference materials were shown by repeated measurements over a period of several years. SRM 2373 is a well characterized genomic DNA reference material that can be used to improve the confidence of the measurements of HER2 gene copy number.

Performance of the reconstruction of large impact parameter tracks in the inner detector of ATLAS (2023)

Abstract Searches for long-lived particles (LLPs) are among the most promising avenues for discovering physics beyond the Standard Model at the Large Hadron Collider (LHC). However, displaced signatures are notoriously difficult to identify due to their ability to evade standard object reconstruction strategies. In particular, the ATLAS track reconstruction applies strict pointing requirements which limit sensitivity to charged particles originating far from the primary interaction point. To recover efficiency for LLPs decaying within the tracking detector volume, the ATLAS Collaboration employs a dedicated large-radius tracking (LRT) pass with loosened pointing requirements. During Run 2 of the LHC, the LRT implementation produced many incorrectly reconstructed tracks and was therefore only deployed in small subsets of events. In preparation for LHC Run 3, ATLAS has significantly improved both standard and large-radius track reconstruction performance, allowing for LRT to run in all events. This development greatly expands the potential phase-space of LLP searches and streamlines LLP analysis workflows. This paper will highlight the above achievement and report on the readiness of the ATLAS detector for track-based LLP searches in Run 3.
