Secure multiple‐input single‐output communication – Part I: secrecy rates and switched power allocation (2014)

The use of multiple‐antenna arrays has attracted much attention for the physical layer security of wireless systems, where the so‐called artificial‐noise solution can be applied to enhance the communication confidentiality. In the first part of this study, the authors consider secure communication over a multiple‐input single‐output Rayleigh‐fading channel in the presence of a multiple‐antenna eavesdropper – referred to as a multiple‐input single‐output multiple‐eavesdropper (MISOME) wiretap channel. Specifically, secure beamforming with artificial noise is treated when the transmitter has access to full channel state information (CSI) of a legitimate channel but only partial CSI of an eavesdropper channel. First, the optimal power allocation between the information‐bearing signal and artificial noise (or simulated interference) is derived to maximise the achievable secrecy rate in the presence of a weak or strong eavesdropper. Then, the first‐order optimal power allocation strategy is developed in a switched fashion by selecting the best of weak‐ and strong‐eavesdropper solutions for a general eavesdropping attack, and a closed‐form expression is derived for the ergodic secrecy rate achieved by secure beamforming with this switched power allocation in the MISOME wiretap channel. The numerical results show that the switched power allocation is a simple but effective approach that nearly achieves the optimal secrecy rate.
Efficient self-seeding of a pulsed Ti:sapphire laser (1998)

Summary form only given. We report the tunable single longitudinal mode (SLM) operation of a pulsed Ti:sapphire laser based on a simple, dual cavity, Littman-type stable resonator geometry, which routinely generates SLM output pulses with several-nanosecond durations and energies up to 10 mJ.
A 0.7-mW/2-GHz dual modulus prescaler IC (2002)

Using a low-power flip-flop that does not heavily load input circuits, we designed a dual modulus divide-by-128 or 129 prescaler IC for applications in wireless communication services. We fabricated it with 0.35-/spl mu/m gate-length high electron mobility transistors (HEMTs) and direct coupled FET logic (DCFL) technology. The prescaler operates at an input frequency of 2 GHz and has a power dissipation of 0.72 mW at a supply voltage of 0.8 V and of 1.24 mW at 1.2 V. The maximum operating frequencies are 2.35 GHz at 0.8 V and 2.28 GHz at 1.2 V.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
High-Accuracy Stochastic Computing-Based FIR Filter Design (2018)

In this paper we propose a novel Stochastic Computing (SC) Finite Impulse Response (FIR) filter design to improve the overall accuracy. Since SC is generated probabilistically, it incurs inherent SC process error, i.e. the larger number of SC process blocks, the larger error probability. Moreover, generation of SC from lower binary radix value produces higher percentage of error as compared to generation from higher value. In our SC FIR design, we reduce the number of SC processing blocks by reducing the number of FIR stages using fast FIR algorithm (FFA). Further we improve the inner-product performance by re-ordering the FIR filter parameters to generate higher-value SC input. Confirmed by the numerical analysis and simulation results, our novel design can implement higher-order FIR filter without reducing its output performance.

Tailoring the Antibody Response to Aggregated Aß Using Novel Alzheimer-Vaccines (2015)

Recent evidence suggests Alzheimer-Disease (AD) to be driven by aggregated Aß. Capitalizing on the mechanism of molecular mimicry and applying several selection layers, we screened peptide libraries for moieties inducing antibodies selectively reacting with Aß-aggregates. The technology identified a pool of peptide candidates; two, AFFITOPES AD01 and AD02, were assessed as vaccination antigens and compared to Aβ1-6, the targeted epitope. When conjugated to Keyhole Limpet Hemocyanin (KLH) and adjuvanted with aluminum, all three peptides induced Aß-targeting antibodies (Abs). In contrast to Aß1-6, AD01- or AD02-induced Abs were characterized by selectivity for aggregated forms of Aß and absence of reactivity with related molecules such as Amyloid Precursor Protein (APP)/ secreted APP-alpha (sAPPa). Administration of AFFITOPE-vaccines to APP-transgenic mice was found to reduce their cerebral amyloid burden, the associated neuropathological alterations and to improve their cognitive functions. Thus, the AFFITOME-technology delivers vaccines capable of inducing a distinct Ab response. Their features may be beneficial to AD-patients, a hypothesis currently tested within a phase-II-study.
Regorafenib (BAY 73-4506) in advanced colorectal cancer: a phase I study (2012)

Conspicuous Character Patterns (2009)

Detection of characters in scenery images is often a very difficult problem. Although many researchers have tackled this difficult problem and achieved a good performance, it is still difficult to suppress many false alarms and although missings. This paper investigates a conspicuous character pattern, which is a special pattern designed for easier detection. In order to have an example of the conspicuous character pattern, we select a character font with a larger distance from a non-character pattern distribution and, simultaneously, with a smaller distance from a character pattern distribution. Experimental results showed that the character font selected by this method is actually more conspicuous (i.e., detected more easily) than other fonts.
Screening of dominantly inherited Charcot–Marie–Tooth neuropathies (1993)

Sixty-three families with dominantly inherited Charcot-Marie-Tooth (CMT) neuropathies including 730 subjects (total) from which 356 affected were studied clinically, electrophysiologically (MNCVs and EMGs), by genetic linkage, and screened for DNA duplication. Thirty-eight families (60.3%) were type 1A (demyelinating CMT mapped on chromosome 17). DNA duplication was present in 36 families (94.8% of CMT1A families). One CMT1A family (2.6%) showed no duplication but suggested genetic linkage with markers of chromosome 17. One CMT1A family (2.6%) revealed nonduplication in some affected members and duplication in other affected members. The disease in that family segregated with the same chromosome 17 markers regardless of duplication status. The other CMT families with dominant inheritance but without duplication included one family with CMT1B (demyelinating CMT mapped on chromosome 1) (1.6%), 14 families with CMT2 axonal neuropathy (22.2%), and 10 families with X-linked dominant CMT (15.9%).

Mutations in multiple components of the nuclear pore complex cause nephrotic syndrome (2018)

Steroid-resistant nephrotic syndrome (SRNS) almost invariably progresses to end-stage renal disease. Although more than 50 monogenic causes of SRNS have been described, a large proportion of SRNS remains unexplained. Recently, it was discovered that mutations of NUP93 and NUP205, encoding 2 proteins of the inner ring subunit of the nuclear pore complex (NPC), cause SRNS. Here, we describe mutations in genes encoding 4 components of the outer rings of the NPC, namely NUP107, NUP85, NUP133, and NUP160, in 13 families with SRNS. Using coimmunoprecipitation experiments, we showed that certain pathogenic alleles weakened the interaction between neighboring NPC subunits. We demonstrated that morpholino knockdown of nup107, nup85, or nup133 in Xenopus disrupted glomerulogenesis. Re-expression of WT mRNA, but not of mRNA reflecting mutations from SRNS patients, mitigated this phenotype. We furthermore found that CRISPR/Cas9 knockout of NUP107, NUP85, or NUP133 in podocytes activated Cdc42, an important effector of SRNS pathogenesis. CRISPR/Cas9 knockout of nup107 or nup85 in zebrafish caused developmental anomalies and early lethality. In contrast, an in-frame mutation of nup107 did not affect survival, thus mimicking the allelic effects seen in humans. In conclusion, we discovered here that mutations in 4 genes encoding components of the outer ring subunits of the NPC cause SRNS and thereby provide further evidence that specific hypomorphic mutations in these essential genes cause a distinct, organ-specific phenotype.
Chained cross-training of workers for robust performance (2004)

Training workers to perform multiple tasks can improve workforce agility for dealing with variations in workload. However, cross-training can be costly, time consuming to implement, is limited by worker learning capacity, and can lead to ambiguity about work responsibilities. Therefore, it is important to implement cross-training in the most efficient way and especially, due to the training time required, in a way that is robust to system changes. We use queueing and simulation analysis to investigate cross-training in the context of maintenance in a manufacturing plant. The tasks are independent and can be represented as a set of parallel queues that are served by dedicated and cross-trained workers. We propose a cross-training strategy called chaining, in which a few workers are strategically cross-trained, and show that it yields most of the benefits of cross-training all workers, with much less effort. Most importantly, we demonstrate that cross-training workers to form a “complete chain” is extremely robust in the following ways: (i) it is insensitive to the variety of ways a complete chain can be formed; (ii) it performs well even if there are major changes to or uncertainty in system parameters (such as mean task arrival rates); and (iii) performance is insensitive to control decisions that, without complete chaining, can significantly harm performance.
<title>Multiple-component analysis of cigarette combustion gases on a puff-by-puff basis using a dual infrared tunable diode laser system</title> (1999)

A dual infrared tunable diode laser system (IR-TDL) has been developed for the simultaneous detection of multiple gaseous components in cigarette smoke. The high spectral resolution (0.001 cm<SUP>-1</SUP>) and rapid time response (20 Hz) of the TDL system are ideal for separating the absorptions from the multitude of gas phase components found in this matrix. The combustion products are sampled into a 0.3 liter, 18 meter multiple pass absorption cell with a flow response time of 0.15 seconds, which provides ample time resolution to observe variations within each 2-second puff. Two independent beam paths allow simultaneous detection in two wavelength regions; the first for ethylene and ammonia and the second for formaldehyde. Rapid scan-sweep integration with direct absorption permits absolute gas concentrations to be determined on-line. A nonlinear least squares procedure is used for `fingerprint' fitting of up to four gases with each diode. Results demonstrating the instrument sensitivity and time response, along with potential caveats, for several gaseous components will be presented.
Formation of Surface Impurities on Lithium–Nickel–Manganese–Cobalt Oxides in the Presence of CO2 and H2O (2021)

Surface impurities involving parasitic reactions and gas evolution contribute to the degradation of high Ni content LiNi<sub><i>x</i></sub>Mn<sub><i>y</i></sub>Co<sub><i>z</i></sub>O<sub>2</sub> (NMC) cathode materials. The transient kinetic technique of temporal analysis of products (TAP), density functional theory, and infrared spectroscopy have been used to study the formation of surface impurities on varying nickel content NMC materials (NMC811, NMC622, NMC532, NMC433, NMC111) in the presence of CO<sub>2</sub> and H<sub>2</sub>O. CO<sub>2</sub> reactivity on a clean surface as characterized by CO<sub>2</sub> conversion rate in the TAP reactor follows the order: NMC811 > NMC622 > NMC532 > NMC433 > NMC111. The capacity of CO<sub>2</sub> uptake follows a different order: NMC532 > NMC433 > NMC622 > NMC811 > NMC111. Moisture pretreatment slows down the direct CO<sub>2</sub> adsorption process and creates additional active sites for CO<sub>2</sub> adsorption. Electronic structure calculations predict that the (012) surface is more reactive than the (1014) surface for CO<sub>2</sub> and H<sub>2</sub>O adsorption. CO<sub>2</sub> adsorption leading to carbonate formation is exothermic with formation of ion pairs. The average CO<sub>2</sub> binding energies on the different materials follow the CO<sub>2</sub> reactivity order. Water hydroxylates the (012) surface and surface OH groups favor bicarbonate formation. Water creates more active sites for CO<sub>2</sub> adsorption on the (1014) surface due to hydrogen bonding. The composition of surface impurities formed in ambient air exposure is dependent on water concentration and the percentage of different crystal planes. Different surface reactivities suggest that battery performance degradation due to surface impurities can be mitigated by precise control of the dominant surfaces in NMC materials.
Athermal, fabrication-tolerant Si-SiN FIR filters for a silicon photonics foundry platform (2023)

A means of athermalizing unbalanced Mach-Zehnder interferometers on a 300 mm silicon photonics foundry platform utilizing Si and SiN layers to produce the path imbalance is demonstrated. This technique can be applied to all other forms of finite impulse response filters, such as arrayed waveguide gratings. Wafer scale performance of fabricated devices is analyzed for their expected performance in the target application: odd-even channel (de)-interleavers for dense wavelength division multiplexing links. Finally, a method is proposed to improve device performance to be more robust to fabrication variations while simultaneously maintaining athermality.
Mapping the location of psoralen crosslinks on RNA by mung bean nuclease sensitivity of RNA.DNA hybrids. (1985)

An indirect high resolution method has been developed for finding the location of intrastrand crosslinks in RNA. An end-labeled DNA strand that overlaps the approximate crosslink position is hybridized to the RNA and then treated with mung bean nuclease. The resulting digest is analyzed on a sequencing-type gel. The method was tested with the major psoralen crosslink seen in the 16S rRNA of inactivated Escherichia coli 30S ribosomal subunits. This crosslink was previously mapped between residues 930 +/- 25 and a region close to the 3' end by electron microscopy. The new indirect method reveals that the crosslink occurs between residues 919 and 923 and residues 1530 and 1534. When these results are examined in the light of existing consensus secondary structure models for the 16S rRNA, it appears that the Shine-Dalgarno sequence is located close to the peptidyl tRNA binding site.
The use of DNA markers in the pre-clinical diagnosis of familial adenomatous polyposis. (1997)

Familial adenomatous polyposis (FAP), an autosomal dominant inherited disease, confers a high risk of colon cancer. For presymptomatic diagnosis of FAP, we performed linkage studies in three unrelated Israeli families with FAP, using seven polymorphic systems around or at the APC locus on chromosome 5q. These systems are constituted of three DNA probes, recognizing four restriction fragment length polymorphism: C11p11, YN5.48 and pi227; three cytosine-adenine repeat markers: D5S318, D5S346 and MBC; and one intragenic polymorphism: APC-SspI. A meiotic recombination event was detected, apparently between the FAP gene and probe pi227. Based on the different analysis systems, we determined the haplotype at the APC locus in 11 at-risk individuals of the three families, six of whom were found to carry the disease-linked allele. Additionally, we identified a new FAP patient, in whom sigmoidoscopy showed the presence of adenomatous polyps throughout the colon.
Materials Studies of GHZ Split-Ring Resonator Plasma Generators (2018)

Microwave-driven microplasmas have generated interest since they offer many favorable qualities such as the ability to produce high-electron densities while causing little sputtering damage1. Such interest has led to studies of breakdown mechanisms at high-frequencies and small gap sizes <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2-3</sup> . Of particular interest for our work is the generation of microplasmas using microwave resonators since they allow high-electric fields with low power input. A missing aspect of the current literature is the comparative study of the influence of different materials on breakdown and resonator performance. By using different materials it may be possible, for instance, to help elucidate the importance of various breakdown mechanisms. For our materials studies we utilize screen-printed, split-ring resonators (SRRs) for the generation of plasma. The SRRs are fabricated out of both gold and silver. These materials differ in conductivity, work function, and chemical reactivity.
Laser photodissociation of O3− by triple quadrupole mass spectrometry (1981)

Absolute cross sections for the production of both O− and O2− by photodissociation of O3− have been determined at intervals of 0.2 nm or less throughout the range from 380 to 650 nm. The results indicate that both the 2A2 and the 2A1 excited state are accessible in this range. Threshold energies and vibrational assignments are derived from the data. For the transition 2A2←2B1, T00 = 2.046±0.002 eV, υ1′ = 815±10 cm−1, υ2′ = 275±10 cm−1, υ1′′ = 975±10 cm−1, υ2′′ = 590±10 cm−1; for 2A1←2B1, T00 = 2.655 eV, υ1′ = 760±20 cm−1, υ2′ = 190±20 cm−1. The threshold for O2− production is interpreted to yield D(O–O2−)?2.41±0.01 eV, which together with other recent spectroscopic determinations of pertinent thermochemical quantities implies that D(02–O−)?1.388±0.013 eV and D(O2–O)?0.747±0.013. The latter value is in serious disagreement with the literature value of 1.05±0.02 eV determined calorimetrically but is in good agreement with results derived from recent spectroscopic measurements on the positive and negative ions of ozone.

Synthesis of Novel Nitro-substituted Triaryl Pyrazole Derivatives as Potential Estrogen Receptor Ligands (2007)

Novel tetrasubstituted pyrazole derivatives bearing a nitro substituent on their A-phenol ring were synthesized and their binding affinity towards the estrogen receptor (ER) subtypes ERalpha and ERbeta was determined. Among compounds tested, the 2-nitrophenol derivative 5c was found to bind satisfactorily to both estrogen receptor subtypes (RBAalpha=5.17 and RBAbeta=3.27). In general, the introduction of a nitro group into the A ring of these compounds was found to benefit their ERbeta binding abilities.
Enhanced Light Extraction Efficiency in Pulse Laser Deposited Gd2O3 : Eu3 + Thin-Film Phosphors on 2-D PCLs (2005)

thin-film phosphors were pulse laser deposited on nanorod-type two-dimensional (2-D) photonic crystal layers (PCL) with 500 and 600 nm pitches as well as non-PCL substrates, in an attempt to improve the efficiency of light extraction. The extraction efficiency was also calculated based on the finite difference time-domain method. The PL efficiency of the phosphor deposited on the PCL with a 500 nm pitch was improved by a factor of 9.3. A comparison between and revealed that when deposited on PCLs, thin-film phosphors were more promising in terms of both intrinsic PL efficiency and light extraction.
Original Articles (1995)

The von Hippel-Lindau syndrome is the most well known cause of familial renal cancer. Because affected individuals with renal lesions can have complex, multisystem manifestations of von Hippel-Lindau disease, our renal management strategy has included parenchymal sparing surgery whenever possible. From May 1988 to January 1993, 20 patients with hereditary renal cell carcinoma (19 with von Hippel-Lindau disease and 1 with hereditary papillary renal cancer) underwent renal exploration with the intent of performing parenchymal sparing surgery. A total of 7 nephrectomies and 27 parenchymal sparing procedures was performed. Additional procedures performed included 2 bilateral adrenalectomies for pheochromocytomas, 1 resection of a renal vein thrombus and 1 resection of a pancreatic islet cell tumor. Renal atrophy occurred in 3 of 27 kidneys (11%) treated by parenchymal sparing surgery. In 8 kidneys of 7 patients new solid lesions developed and in 14 kidneys of 12 patients no new solid lesions developed during a mean followup of 26 months (range 6 to 60 months). The use of parenchymal sparing surgery in patients with familial forms of kidney cancer is based on a desire to maintain renal function as long as possible while reducing the risk of metastases. The potential advantages and disadvantages of more ablative surgical treatment requiring subsequent dialysis or transplantation in patients with existing or potential central nervous system, eye, pancreas and/or adrenal tumors must be weighed against the possibility of renal cancer metastases or recurrence when deciding on the use of parenchymal sparing surgery.
