Design of layered radio environment maps for RAN optimization in heterogeneous LTE systems (2011)

In this contribution a layered radio environment map (REM) architecture is designed and applied in the framework of radio-access network optimization for heterogeneous LTE systems that comprise both macrocells and femtocells. We define layer as the hierarchical representation of a geographical area. In each layer, different instances of the same architectural block will have different spatial/temporal granularities, associated with network functionalities. The effectiveness of the proposed architecture to support LTE functions like automatic neighbor relation (ANR) and minimization of drive tests (MDT) is discussed. In addition, we present the benefits of using such architecture in the implementation of these functions along with its potential to bring performance gains.
Maximal adversarial perturbations for obfuscation: Hiding certain attributes while preserving rest (2019)

In this paper we investigate the usage of adversarial perturbations for the purpose of privacy from human perception and model (machine) based detection. We employ adversarial perturbations for obfuscating certain variables in raw data while preserving the rest. Current adversarial perturbation methods are used for data poisoning with minimal perturbations of the raw data such that the machine learning model's performance is adversely impacted while the human vision cannot perceive the difference in the poisoned dataset due to minimal nature of perturbations. We instead apply relatively maximal perturbations of raw data to conditionally damage model's classification of one attribute while preserving the model performance over another attribute. In addition, the maximal nature of perturbation helps adversely impact human perception in classifying hidden attribute apart from impacting model performance. We validate our result qualitatively by showing the obfuscated dataset and quantitatively by showing the inability of models trained on clean data to predict the hidden attribute from the perturbed dataset while being able to predict the rest of attributes.
Reduction of Gordon-Mollenauer phase noise by midlink spectral inversion (2005)

We show that spectral inversion can be employed for regeneration to reduce the effect of phase noise (Gordon-Mollenauer phase noise) in a nonreturn-to-zero differential phase-shift-keying based transmission system. Several locations of the spectral inverter in an eight-span transmission link have been investigated. We show that the best results are obtained when the spectral inverter is placed in the middle of the link. Compared to the transmission system without spectral inverter, an improvement of over four decades in bit-error-rate performance is achieved.
Electron microscopy of DNA crosslinked with trimethylpsoralen: test of the secondary structure of eukaryotic inverted repeat sequences. (1976)

It has been suggested that inverted repeat (palindrome) sequences, which are widespread in eukaryotic genomes, exist in two alternate configurations, a linear form and a cruciform. To investigate the relative frequency of these forms, the DNA of intact mouse tissue culture cells was covalently crosslinked with 4,5',8-trimethylpsoralen (me3-psoralen) in order to prevent rearrangement of the DNA secondary structure during DNA isolation. The distribution of me3-psoralen crosslinks was determined by electron microscopy after denaturation of the DNA in the presence of glyoxal. Because of the high frequency and the relatively uniform distribution of the me3-psoralen crosslinks, it could be concluded that almost all of the inverted repeat sequences had been crosslinked. In spite of this, no significant number of cruciforms was detected by electron microscopy. To determine whether the me3-psoralen might itself be disrupting cruciform structures, cruciforms were first produced in isolated Tetrahymena rDNA by heat treatment and then crosslinked in vitro. The crosslinking was found to stabilize rather than disrupt these cruciforms. We conclude that the inverted repeat sequences of the mouse tissue culture cells we tested are predominantly in linear forms rather than in cruciform structures inside the cell.
Density functional theory study of deep traps in silicon nitride memories (2006)

Using density functional theory, the interaction of hydrogen with a nitrogen vacancy in β-Si3N4 is investigated. A single H atom was found to be energetically favorable over non- and doubly protonated vacancies. The traps composed of excess silicon and hydrogen have negative correlation energy which is connected with different distances of Si–H and Si–Si bonds in charged and neutral states. The energy gains after trapping are consistent with trap activation energies in advanced silicon nitride memories. Based on the present results, a model of memory traps is proposed.

Variable-speed-drive-based sensorless estimation of pump system reservoir fluid level (2020)

This paper proposes a soft sensor for estimating the surface level of a reservoir in a centrifugal pumping system. The proposed soft sensor can be implemented in the control scheme of a variable-speed drive and requires no extra equipment to function.
Field experiments on multipath interference canceller associated with AMC in HSDPA (2004)

This paper presents field experimental results on a multipath interference canceller (MPIC) associated with adaptive modulation and channel coding (AMC) in an actual multipath fading channel in high-speed downlink packet access (HSDPA). In the implemented MPIC receiver with four Rake fingers at maximum, a multipath interference (MPI) replica of each resolved path is precisely generated utilizing the common pilot channel (CPICH), and subtracted from the received signal in a four-stage parallel configuration, thereby resulting in an improvement in throughput caused by suppression of strong MPI from the high-speed downlink shared channel (HS-DSCH). Furthermore, we employ four modulation and channel coding schemes (MCSs), MCS1 (QPSK data modulation with the channel coding rate R = 1/2, hereafter simply referred to as QPSK with R = 1/2), MCS2 (QPSK with R = 3/4), MCS3 (16QAM with R = 1/2), and MCS4 (16QAM with R = 3/4) along with nine-code multiplexing with the spreading factor of SF = 16. Experimental results elucidate that the measured throughput employing MPIC is significantly improved compared to that with a matched filter (MF)-based Rake receiver in an actual multipath fading channel at the average vehicular speed of approximately 30 km/h. Furthermore, the peak throughput of approximately 6.5 Mbps is achieved at nine-code multiplexing under sufficiently high received signal-to-interference power ratio (SIR) conditions (thus, the throughput of approximately 6.5 Mbps at nine-code multiplexing suggests possibility of peak throughput above 10 Mbps when 15-code multiplexing is applied).
Microfluidic bypass manometry: highly parallelized measurement of flow resistance of complex channel geometries and trapped droplets (2017)

Current lithography methods allow facile fabrication of microfluidic conduits where not only the shape of the bounding walls can be arbitrarily varied but also the internal conduit space can be laden with a variety of microstructures and wetting properties. This virtually infinite design space of microfluidic geometries brings in the challenge of how to quantify fluid resistance in a large number of microfluidic conduits, while maintaining operational simplicity. We report a versatile experimental technique referred to as microfluidic bypass manometry for measurement of pressure drop versus flow rate (ΔP-Q) relations in a parallelized manner. The technique involves introducing co-flowing laminar streams into a microfluidic network that contains a series of loops, where each loop is comprised of a test geometry and a bypass channel as a flow-rate sensing element. We optimize the network geometry and present operational considerations for microfluidic bypass manometry. To demonstrate the power of our technique, we used single-phase fluids and measured ΔP-Q relations simultaneously for forty test geometries ranging from linear to contraction-expansion to serpentine to pillar-laden microchannels. To expand the capabilities of the method, we measured ΔP-Q relations for similar-sized oil droplets trapped in microcavities where the cavity geometry spans from prisms of 3-10 sides to circular disks. We found in all cases, the ΔP-Q relation is nonlinear and the flow resistance of droplets is sensitive to confinement. At high flow rates, the drop resistance depends on the cavity geometry and is higher in a triangular prism compared to a circular disk. We compared the measured flow resistance of single-phase fluids and droplets in different microfluidic geometries to that from computational fluid dynamics simulations and found them to be in excellent agreement. Given the simplicity and versatility of the microfluidic bypass manometry method, we anticipate that it may find broad application in several areas including design of lab-on-chip devices, laminar drag reduction and mechanics of deformable particles.
Synchronizing Time Servers (1987)

A time service in a distributed system may be used both for multiprocess synchronization and for simply finding out what time it is. For synchronization, the time provided by di#erent servers should be closely synchronized. For telling time, the time provided by each server should be a close approximation to Universal Time (the international time standard). Algorithms are presented for implementing a fault-tolerant time service that meets both requirements.
Single-walled carbon nanotube growth using [Fe3(µ3-O)(µ-O2CR)6(L)3]n+complexes as catalyst precursors (2005)

We present herein the VLS growth of SWNTs from oxo-hexacarboxylate-triron precursors, [Fe(3)O(O(2)CCH(3))(6)(EtOH)(3)] and [Fe(3)O(O(2)CCH(2)OMe)(6)(H(2)O)(3)][FeCl(4)], on spin-on-glass surfaces, using C(2)H(4)/H(2) (750 degrees C) and CH(4)/H(2) (800 and 900 degrees C) growth conditions. The SWNTs have been characterized by AFM, SEM and Raman spectroscopy. The characteristics of the SWNTs are found to be independent of the identity of the precursor complex or the solvent from which it is spin-coated. The as grown SWNTs show a low level of side-wall defects and have an average diameter of 1.2-1.4 nm with a narrow distribution of diameters. At 750 and 800 degrees C the SWNTs are grown with a range of lengths (300 nm-9 microm), but at 900 degrees C only the longer SWNTs are observed (6-8 microm). The yield of SWNTs per unit area of catalyst nanoparticle decreases with the growth temperature. We have demonstrated that spin coating of molecular precursors allows for the formation of catalyst nanoparticles suitable for growth of SWNTs with a high degree of uniformity in the diameter, without the formation of preformed clusters of a set diameter.

Search forZ′resonances decaying tott¯indilepton+jetsfinal states inppcollisions ats=7  TeV (2013)

A search for resonances decaying to top quark-antiquark pairs is performed using a dilepton jets data sample recorded by the CMS experiment at the LHC in pp collisions at ffiffi ffi s p 7 TeV corresponding to an integrated luminosity of 5:0 fb 1 . No significant deviations from the standard model background are observed. Upper limits are presented for the production cross section times branching fraction of top quark-antiquark resonances for masses from 750 to 3000 GeV. In particular, the existence of a leptophobic topcolor particle Z 0 is excluded at the 95% confidence level for resonance masses M Z 0 < 1:3 TeV for Z 0 0:012M Z 0 , and M < 1:9 TeV for Z 0 0:10M Z 0 .
A non-coherent AF scheme for two-way wireless relay networks based on packings in Grassmann manifolds (2010)

Motivated from results for the point-to-point block MIMO fading channels without channel knowledge, we propose an AF scheme for the non-coherent two-way relaying channel with the half-duplex constraint. The communication takes place in two phases, multicast and broadcast. In the multicast phase the terminals send the signals simultaneously. In the broadcast phase, the relays resend the signal received in the broadcast phase. The code construction is based on subspace packings in the Grassmann manifolds. We show, that although no channel knowledge is assumed at either the terminals or at the relays, the terminals are able to subtract the self-interference part of the received signal. The performance analysis shows that the noncoherent two-way relaying outperforms non-coherent one-way relaying and delivers the promise of increased spectral efficiency.
SORL1‐variant carriers in ADES‐ADSP: A higher level of variant pathogenicity associates with earlier age at onset of Alzheimer's disease (2020)

Abstract Background Recent reports indicated that extremely rare protein truncating or missense variants in the SORL1 gene are associated with an increased risk and possibly a causative effect on developing Alzheimer’s Disease (AD). Here, we investigated the relationship between the predicted variant pathogenicity and the age at AD onset (a.a.o.) in the largest whole exome sequencing (WES) dataset of AD cases and controls world‐wide. Method We combined sequencing data from the ADES and ADSP consortia on a single server. After quality control and exclusion of carriers of pathogenic variants in genes associated with Mendelian inheritance of AD, 12,675 AD cases and 8,693 controls were available for analysis. Non‐synonymous variants were scored using the REVEL algorithm, and loss‐of‐function (LOF) variants were predicted using LOFTEE. The variant‐burden was determined across all genes and odds ratios (OR) for AD‐status were calculated using a multinomial logistic test across age groups. Result Of all genes in the genome, rare variants in the SORL1 gene had the strongest association with AD (p = 6.4 × 10 −14 ). We identified 320 rare nonsynonymous missense and loss‐of‐function SORL1 variants (MAF&lt;1 × 10 −4 ). The carrier frequency in AD cases with a.a.o. &lt;65, a.a.o. &gt;65 and cognitively healthy controls was respectively 1.9%, 1.3%, 0.7%. Carrying a SORL1 variant associated with an increased risk of early onset AD (Figure A). Specifically, carriers of LOF variants had a median a.a.o. of 63 years (Figure C), and this associated with a 24.8‐fold increased chance of developing AD before 65 years compared to non‐carriers (Figure B). The median a.a.o. for carriers of nonsynonymous variants with REVEL&gt;75 was 70 years, and such variants associated with estimated 7.6‐fold increased risk of developing AD between 65‐70 years (Figure B). Variants with lower REVEL scores associated with a lower AD‐risk. Conclusion The abundance of predicted pathogenic SORL1 genetic variants and the profound effect on AD risk makes the SORL1 protein product a promising target for the design of selective treatment strategies for affected individuals. Further, our results open the discussion of whether and how AD‐affected SORL1 ‐variant carriers and their (presymptomatic) family‐members should be clinically counselled. For this, pathogenicity screens that distinguish between pathogenic and non‐pathogenic non‐synonymous variants are warranted.
An Angiotensin I-Converting Enzyme Mutation (Y465D) Causes a Dramatic Increase in Blood ACE via Accelerated ACE Shedding (2011)

The Y465D substitution results in dramatic increase in the rate of ACE shedding and is associated with significant local conformational changes in ACE. These changes could result in increased ACE dimerization and accessibility of the stalk region or the entire sACE, thus increasing the rate of cleavage by the putative ACE secretase (sheddase).
On Assessing the Competitiveness of IT Service Solutions (2013)

We present a method and a system for assessing the competitiveness of IT service solutions. The method enables sales teams to assess the competitiveness of their IT service solutions created during the sales phase in response to request for proposal (RfP). It involves comparing unit costs and unit prices of a given solution with those of client expectations, comparable prior deals and agreed upon rates defined within an IT service provider organization, competition and market. Our contributions include an approach to modeling IT service solutions in a consistent manner to enable comparison. This is a pre-requisite to the second step of comparing IT service solutions. Second, an approach to comparing IT service solutions is proposed. The approach takes into account structured and unstructured attributes as well as qualitative and quantitative values of attributes during comparison. We are currently performing precision and recall experiments at an IT service organization using 200 prior deals. Initial results are encouraging. In the absense of any prior tools to do this, our system is already proving to be a valuable asset to the IT service organization that we are developing the solution for.
Perthes’ disease after the age of twelve years (1999)

In order to define the prognostic factors in Perthes’ disease in children older than 12 years, we reviewed 15 patients at the end of growth who were aged 12.1 to 14 years at presentation. The patients with the worst long-term prognosis (Stulberg class V) were compared with the others for age, skeletal maturity and remaining growth (Oxford method), as well as Catterall and Waldenström classifications at presentation. A significant difference (p = 0.001) was found for remaining growth (25% in Stulberg class V and 35% in the others) and also for the results at the end of growth when the remaining growth was over 30%, since this allowed sufficient time for reformation and remodelling of the femoral head.
Robust Beam Management for Mobility in mmWave Systems (2018)

Proactive communication among vehicles and infrastructure units is an essential ingredient to enable fully autonomous driving. 5G NR is a candidate technology to power the technical and functional requirements for vehicle-to-everything (V2X) communication, through enhanced resource allocation and usage of mmWave spectral channels. Beam acquisition and tracking is crucial for successful operation in mmWave V2X. Traditional beam sweep strategies to achieve beam alignment suffer, however, from large overhead and latency that renders them impractical to support mobility applications. In this paper, we explore robust communication for NR V2X. We argue that imposing a hierarchical structure at the sidelink through the election of a local node scheduler is important for efficient mobility management. We further focus on the feasibility of mmWave V2X, and present field measurement results that show that mmWave V2X are capable of achieving long ranges and are generally robust to blockage, even with a wide beam at the transmitter. Building on the measurement results, we discuss key beam management building blocks for mmWave V2X that take the antenna architecture, and the stringent mobility requirements into consideration, to achieve beam alignment.
Kevlar 49 composite performance: Dependence on thermoset resin microstructure (1984)

Abstract Molecular structures for cured, thermoset resins have been examined by analyses of resin extracts by gel permeation chromatography. Numerical interpretation of leached oligomeric fractions coupled with kinetic reaction theory yields microscopic estimates of the network's structure, including crosslink average molecular weight. Leached monomeric fractions describe extent of cure. Analyses of test data incorporate irreversible, mechanical deformations for neat resin castings and for filament wound, Kevlar 49 composites. Heat distortion temperatures correlate with crosslink architecture. Short beam shear strength data for naval ordinance laboratory rings and pressure vessel burst performance are examined in terms of the resin's molecular structure. Variations in resin cure observed by positive feedback via chromatography indicate fluctuations in extent of crosslink development. Test specimen performance correlates with these microscopic, molecular distributions. Resin applications include filament wound composites for the aerospace industry, anhydride cured epoxies, and amine cured epoxies. The former resin is an elastic body at ambient test conditions. A third resin, a crosslinked resin of 1,2 polybutadiene/t‐butylstyrene, is in final developmental stages and may exhibit a higher degree of viscoelastic behavior.

The present invention is directed to methods for preparing sorbose from glucose, said method comprising: (a) contacting the glucose with a silica-containing structure comprising a zeolite having a topology of a 12 membered-ring or larger, an ordered mesoporous silica material, or an amorphous silica, said structure containing Lewis acidic Ti.sup.4+ or Zr.sup.4+ or both Ti.sup.4+ and Zr.sup.4+ framework centers, said contacting conducted under reaction conditions sufficient to isomerize the glucose to sorbose. The sorbose may be (b) separated or isolated; or (c) converted to ascorbic acid.
Application of digital filtering to noise reduction in exponential decays (1986)

Application of a simple digital filter to decays which can be represented as sums of exponential functions substantially reduces noise in the measurements, while at the same time leaving rate constants invariant and changing amplitudes of different exponential components in a known way. With some limitations this noise reduction method is also applicable to periodic and quasi-periodic phenomena.
Transcription from the P2 promoter of human protooncogene myc is suppressed by retinoic acid through an interaction between the E2F element and its binding proteins. (1994)

When human promyelocytic leukemia cell line HL60 was treated with retinoic acid (RA), considerable suppression of protooncogene myc expression was achieved before granulocytic differentiation became evident. From transient transfection experiments using the reporter plasmid containing exon 1 and its 2.3 kilobases upstream of the c-myc gene fused to the chloramphenicol acetyltransferase gene, it was indicated that this suppression was mainly attributable to the level of transcription initiation. Deletion down to 95 base pairs upstream of the P2 promoter did not change the suppressive effect of RA on c-myc gene expression. Mobility shift assays with respect to the P2 promoter region revealed that the 15-base pair fragment located between P1 and P2 promoters was responsive to the RA treatment. This fragment included the E2F binding site in the c-myc P2 promoter region, and a difference of shifted bands between RA-treated and untreated HL60 cells was due to complex formation of E2F and retinoblastoma protein. The present results suggest that E2F plays an important role in the process of cell differentiation by RA and that a change of the E2F binding pattern induced by RA contributes to the suppression of c-myc gene expression preceding granulocytic differentiation.
