Secondary Ion Mass Spectrometry (SIMS) (2016)

This document contains recommendations for terminology in mass spectrometry. Development of standard terms dates back to 1974 when the IUPAC Commission on Analytical Nomenclature issued recommendations on mass spectrometry terms and definitions. In 1978, the IUPAC Commission on Molecular Structure and Spectroscopy updated and extended the recommendations and made further recommendations regarding symbols, acronyms, and abbreviations. The IUPAC Physical Chemistry Division Commission on Molecular Structure and Spectroscopy’s Subcommittee on Mass Spectroscopy revised the recommended terms in 1991 and appended terms relating to vacuum technology. Some additional terms related to tandem mass spectrometry were added in 1993 and accelerator mass spectrometry in 1994. Owing to the rapid expansion of the field in the intervening years, particularly in mass spectrometry of biomolecules, a further revision of the recommendations has become necessary. This document contains a comprehensive revision of mass spectrometry terminology that represents the current consensus of the mass spectrometry community.
Accelerated Lifetime Testing of High Power Lithium Titanate Oxide Batteries (2018)

This paper presents results obtained from extensive accelerated lifetime tests performed on a high power Lithium Titanate Oxide (LTO) battery cell. The tests were performed at elevated temperatures, with different C-rates, and for different cycle depths. The obtained results have shown a very good capacity retention and a reduced internal resistance increase (and subsequently reduced power capability decrease) even after more than 8000 cycles performed at 42.5°C. We found out that both the capacity and the internal resistance have been degrading faster when the LTO-based battery cells were cycled with a smaller C-rate (i.e., 1C) than with a higher C-rate (i.e., 3C). Moreover, based on the harvested aging results, we discovered that the capacity and not the internal resistance is the performance parameter of the tested LTO-based battery cells, which will limit their lifetime.
REVISION OF THE ACETABULAR COMPONENT WITHOUT CEMENT AFTER TOTAL HIP ARTHROPLASTY (2005)

Abstract: We previously reported our results at a minimum of three and seven years after use of a porous-coated acetabular metal shell in a consecutive series of 138 revision total hip arthroplasties. The current report presents the longer-term outcomes of these procedures, at fifteen to nineteen years postoperatively. A total of twenty metal shells (14%) underwent repeat revision. Seven of the repeat revisions were performed because of recurrent dislocation, seven were done at the time of femoral revision surgery, and six were done because of infection. Nineteen of the revised shells were well fixed, and one was aseptically loose. Of the sixty-seven hips in which the acetabular component survived for more than fifteen years after the index operation, two (3%) required a change of the modular acetabular liner because of wear or osteolysis. Nine (16%) of the fifty-seven hips with at least fifteen years of radiographic follow-up had an osteolytic lesion of >1 cm in diameter. The fifteen-year survival rate of the metal shells, with failure defined as revision because of loosening or as radiographic evidence of loosening, was 97%. Revision total hip arthroplasty with this cementless acetabular component has been followed by excellent component survivorship at fifteen years; the most common reasons for repeat revision were recurrent dislocation and infection. Level of Evidence: Therapeutic Level IV. See Instructions to Authors for a complete description of levels of evidence.
<title>MEMS/MOEMS for lightwave networks: Can little machines make it big?</title> (2000)

Silicon micromechanics in an emerging field which is beginning to impact almost every area of science and technology. In areas as diverse as the chemical, automotive, aeronautical, cellular and optical communication industries, Silicon micromachines are becoming the solution of choice for many problems. In this paper we will describe what they are, how they are built, and show how they have the potential to revolutionize lightwave systems. Devices such as optical switches, variable attenuators, active equalizers, add/drop multiplexers, optical crossconnects, gain tilt equalizers, data transmitters and many others are beginning to find ubiquitous application in advanced lightwave systems. We will show examples of these devices and describe some of the challenges in attacking the billions of dollars in addressable markets for this technology.
<title>Privacy-protected biometric templates: acoustic ear identification</title> (2004)

Unique Biometric Identifiers offer a very convenient way for human identification and authentication. In contrast to passwords they have hence the advantage that they can not be forgotten or lost. In order to set-up a biometric identification/authentication system, reference data have to be stored in a central database. As biometric identifiers are unique for a human being, the derived templates comprise unique, sensitive and therefore private information about a person. This is why many people are reluctant to accept a system based on biometric identification. Consequently, the stored templates have to be handled with care and protected against misuse [1, 2, 3, 4, 5, 6]. It is clear that techniques from cryptography can be used to achieve privacy. However, as biometric data are noisy, and cryptographic functions are by construction very sensitive to small changes in their input, and hence one can not apply those crypto techniques straightforwardly. In this paper we show the feasibility of the techniques developed in [5], [6] by applying them to experimental biometric data. As biometric identifier we have choosen the shape of the inner ear-canal, which is obtained by measuring the headphone-to-ear-canal Transfer Functions (HpTFs) which are known to be person dependent [7].
Standardised Outcomes in Nephrology—Children and Adolescents (SONG-Kids): a protocol for establishing a core outcome set for children with chronic kidney disease (2016)

Establishing a core outcome set to be reported in all trials conducted in children with any stage of CKD will enhance the relevance, transparency, and impact of research to improve the lives of children and adolescents with CKD.
SERCA Pump Inhibitors Do Not Correct Biosynthetic Arrest of ΔF508 CFTR in Cystic Fibrosis (2005)

Deletion of phenylalanine 508 (deltaF508) accounts for nearly 70% of all mutations that occur in the cystic fibrosis transmembrane conductance regulator (CFTR). The deltaF508 mutation is a class II processing mutation that results in very little or no mature CFTR protein reaching the apical membrane and thus no cAMP-mediated Cl- conductance. Therapeutic strategies have been developed to enhance processing of the defective deltaF508 CFTR molecule so that a functional cAMP-regulated Cl- channel targets to the apical membrane. Sarcoplasmic/endoplasmic reticulum calcium (SERCA) inhibitors, curcumin and thapsigargin, have been reported to effectively correct the CF ion transport defects observed in the deltaF508 CF mice. We investigated the effect of these compounds in human airway epithelial cells to determine if they could induce deltaF508 CFTR maturation, and Cl- secretion. We also used Baby Hamster Kidney cells, heterologously expressing deltaF508 CFTR, to determine if SERCA inhibitors could interfere with the interaction between calnexin and CFTR and thereby correct the deltaF508 CFTR misfolding defect. Finally, at the whole animal level, we tested the ability of curcumin and thapsigargin to (1) induce Cl- secretion and reduce hyperabsorption of Na+ in the nasal epithelia of the deltaF508 mouse in vivo, and (2) induce Cl- secretion in intestine (jejunum and distal colon) and the gallbladder of the deltaF508 CF mouse. We conclude that curcumin and thapsigargin failed to induce maturation of deltaF508 CFTR, or induce Cl- secretion, as measured by biochemical and electrophysiologic techniques in a variety of model systems ranging from cultured cells to in vivo studies.
Shaping femtosecond laser pulses at short wavelength with grazing-incidence optics (2019)

We present the design of an extreme ultraviolet (XUV) pulse shaper relying on reflective optics. The instrument will allow tailoring of the time-frequency spectrum of femtosecond pulses generated by seeded free-electron lasers (FEL) and high-harmonic generation (HHG) sources down to a central wavelength of ~15 nm. The device is based on the geometry of a 4f grating compressor that is a standard concept in ultrafast laser science and technology. We apply it to shorter wavelengths using grazing-incidence optics operated under ultra-high vacuum conditions. The design blaze angle and the line density of the gratings allow the manipulation of all different harmonics typical for seeded FEL and HHG photon sources without the need of realignment of the instrument and even simultaneously in multi-color experiments. A proof-of-principle pulse shaping experiment using 266 nm laser light has been performed, demonstrating relative phase-control of femtosecond UV pulses.
Compatibility-aware Heterogeneous Visual Search (2021)

We tackle the problem of visual search under resource constraints. Existing systems use the same embedding model to compute representations (embeddings) for the query and gallery images. Such systems inherently face a hard accuracy-efficiency trade-off: the embedding model needs to be large enough to ensure high accuracy, yet small enough to enable query-embedding computation on resource-constrained platforms. This trade-off could be mitigated if gallery embeddings are generated from a large model and query embeddings are extracted using a compact model. The key to building such a system is to ensure representation compatibility between the query and gallery models. In this paper, we address two forms of compatibility: One enforced by modifying the parameters of each model that computes the embeddings. The other by modifying the architectures that compute the embeddings, leading to compatibility-aware neural architecture search (Cmp-NAS). We test Cmp-NAS on challenging retrieval tasks for fashion images (DeepFashion2), and face images (IJB-C). Compared to ordinary (homogeneous) visual search using the largest embedding model (paragon), Cmp-NAS achieves 80-fold and 23-fold cost reduction while maintaining accuracy within 0.3% and 1.6% of the paragon on DeepFashion2 and IJB-C respectively.
Feature fusion for high-accuracy keyword spotting (2014)

This paper assesses the role of robust acoustic features in spoken term detection (a.k.a keyword spotting - KWS) under heavily degraded channel and noise corrupted conditions. A number of noise-robust acoustic features were used, both in isolation and in combination, to train large vocabulary continuous speech recognition (LVCSR) systems, with the resulting word lattices used for spoken term detection. Results indicate that the use of robust acoustic features improved KWS performance with respect to a highly optimized state-of-the art baseline system. It has been shown that fusion of multiple systems improve KWS performance, however the number of systems that can be trained is constrained by the number of frontend features. This work shows that given a number of frontend features it is possible to train several systems by using the frontend features by themselves along with different feature fusion techniques, which provides a richer set of individual systems. Results from this work show that KWS performance can be improved compared to individual feature based systems when multiple features are fused with one another and even further when multiple such systems are combined. Finally this work shows that fusion of fused and single feature bases systems provide significant improvement in KWS performance compared to fusion of singlefeature based systems.
Structure and chemistry of the Sir2 family of NAD+-dependent histone/protein deactylases (2004)

The yeast Sir2 (silent information regulator-2) protein functions as an NAD(+)-dependent histone deacetylase to silence gene expression from the mating-type locus, tolomeres and rDNA and also promotes longevity and genome stability in response to calorie restriction. Homologues of yeast Sir2 have been identified in the three domains of bacteria, archaea and eukaryotes; in mammalian cells, Sir2 proteins also deacetylate non-histone proteins such as the p53 tumour suppressor protein, alpha-tubulin and forkhead transcription factors to mediate diverse biological processes including metabolism, cell motility and cancer. We have determined the X-ray crystal structure of a Sir2 homologue from yeast Hst2 (yHst2), in various liganded forms, including the yHst2/acetyl-Lys-16 histone H4/NAD(+) ternary complex; we have also performed related biochemical studies to address the conserved mode of catalysis by these enzymes as well as the distinguishing features that allow different members of the family to target their respective cognate substrates. These studies have implications for the structure-based design of Sir2-specific small molecule compounds, which might modulate Sir2 function for therapeutic application.

Carbon‐Nanotube‐Templated Microfabrication of Porous Silicon‐Carbon Materials with Application to Chemical Separations (2011)

Abstract Carbon‐nanotube‐templated microfabrication (CNT‐M) of porous materials is demonstrated. Partial chemical infiltration of 3D carbon‐nanotube structures with silicon results in a mechanically robust material, structured from the 10 nm scale to the 100 μm scale. The nanoscale dimensions are determined by the diameter and spacing of the resulting silicon/carbon nanotubes, while the microscale dimensions are controlled by the lithographic patterning of the CNT growth catalyst. We demonstrate the utility of this hierarchical structuring approach by using CNT‐M to fabricate thin‐layer‐chromatography (TLC) separations media with precise microscale channels for fluid‐flow control and nanoscale porosity for high analyte capacity. Chemical separations done on the CNT‐M‐structured media outperform commercial high‐performance TLC media.
Tunable Doppler shift using a time-varying epsilon-near-zero thin film near 1550  nm (2021)

We experimentally investigate the tunable Doppler shift in an 80 nm thick indium-tin-oxide (ITO) film at its epsilon-near-zero (ENZ) region. Under strong and pulsed excitation, ITO exhibits a time-varying change in the refractive index. A maximum frequency redshift of 1.8 THz is observed in the reflected light when the pump light has a peak intensity of ∼140<i>G</i><i>W</i>/<i>c</i><i>m</i><sup>2</sup> and a pulse duration of ∼580<i>f</i><i>s</i>, at an incident angle of 40°. The frequency shift increases with the increase in pump intensity and saturates at the intensity of ∼140<i>G</i><i>W</i>/<i>c</i><i>m</i><sup>2</sup>. When the pump pulse duration increases from ∼580<i>f</i><i>s</i> to ∼1380<i>f</i><i>s</i>, the maximum attainable frequency shift decreases from 1.8 THz to 0.7 THz. In addition, the pump energy required to saturate the frequency shift decreases with the increase in pump pulse duration for ∼<sub>x</sub><1<i>p</i><i>s</i> and remains unchanged for ∼<sub>x</sub>>1<i>p</i><i>s</i> durations. Tunability exists among the pump pulse energy, duration, and incident angle for the Doppler shift of the ITO-ENZ material, which can be employed to design efficient frequency shifters for telecom applications.
The E3 Ubiquitin Ligase NEDD4-1 Mediates Temozolomide-Resistant Glioblastoma through PTEN Attenuation and Redox Imbalance in Nrf2–HO-1 Axis (2021)

These findings demonstrate the critical role of NEDD4-1 in regulating the redox imbalance in TMZ-resistant GBM cells via the degradation of PTEN and the upregulation of the AKT/NRF2/HO-1 signaling pathway. Targeting this regulatory axis may help eliminate TMZ-resistant glioblastoma.

Large-scale taxonomy categorization for noisy product listings (2016)

E-commerce catalogs include a continuously growing number of products that are constantly updated. Each item in a catalog is characterized by several attributes and identified by a taxonomy label. Categorizing products with their taxonomy labels is fundamental to effectively search and organize listings in a catalog. However, manual and/or rule based approaches to categorization are not scalable. In this paper, we compare several classifiers to product taxonomy categorization of top-level categories. We first investigate a number of feature sets and observe that a combination of word unigrams from product names and navigational breadcrumbs work best for categorization. Secondly, we apply correspondence topic models to detect noisy data and introduce a lightweight manual process to improve dataset quality. Finally, we evaluate linear models, gradient boosted trees (GBTs) and convolutional neural networks (CNNs) with pre-trained word embeddings demonstrating that, compared to other baselines, GBTs and CNNs yield the highest gains in error reduction.
Providing Multi-tenant Services with FPGAs: Case Study on a Key-Value Store (2018)

FPGAs can be used to speed up computation and data management tasks in various application domains. In cloud settings, however, high utilization is as important as high performance. In software it is common to co-locate different tenants' workloads on the same servers to increase utilization. Sharing an FPGA is more complex because applications take up physical space on the chip. Even though it is possible to physically partition the FPGA, tenants can have widely different requirements and their needs can also fluctuate over time. In this paper, we take a different approach and provide flexibility to the tenants who are interested in the same type of application but have different workloads and quality of service requirements. We demonstrate our approach of multi-tenant design using a key-value store service but the ideas generalize to other network-facing services as well. A key challenge of multi-tenancy is to efficiently share the underlying hardware while enforcing strict data and performance isolation between tenants. In this paper we demonstrate that, by following a single-pipeline design principle, it is possible to control each tenant's share of network bandwidth and computational resources even for complex, distributed operations. Furthermore, we show how state-machine based logic on the FPGA can be made tenant-aware without introducing significant context-switching overhead. Finally, our hardware design provides flexibility for changing per-tenant shares, allowing the same circuit to be used by one or multiple tenants without performance loss.
Immunization with Haemophilus influenzae type b polysaccharide vaccine at 18 and 24 months of age: evidence of decreased immunogenicity. (1991)

In order to assess the immunogenicity of a two-dose regimen of Haemophilus influenzae type b polysaccharide vaccine, the immune response to vaccine given at both 18 and 24 months of age was compared to the response to a single dose at 24 months of age. Following immunization at 24 months of age, the geometric mean antibody concentration of children previously immunized at 18 months (0.53 micrograms/ml) was significantly lower than that of children who received a single dose of vaccine at 24 months (1.03 micrograms/ml; p = 0.03). A four-fold rise in antibody concentration was demonstrated in 31% of children who had received two immunizations and 53% of children immunized for the first time at 24 months of age (p = 0.02). These results suggest that the administration of a dose of plain polysaccharide vaccine at 18 months of age blunted the response to reimmunization at 24 months of age. A subgroup of children who failed to respond to one or two doses of plain polysaccharide vaccine were immunized with polysaccharide-diphtheria toxoid conjugate vaccine. The majority of these children developed a significant rise in antibody concentration in response to conjugate vaccine.
Advanced antenna solutions for 5G wireless access (2014)

The use of multiple transmit antennas at the base station and device side play an important role already in current 4G/LTE systems, enhancing system performance and extending the data rates that can be provided to the end user. For the future (5G) wireless-access solution advanced antenna solutions are expected to play an even more pronounced role. 5G wireless access needs to provide substantially higher data rates, up to the multi-Gbps range in specific scenarios and with hundreds of Mbps to be generally available in urban/suburban environments, as well as handle traffic volumes hundreds of times higher than today. Advanced multi-antenna transmission will be key to fulfill both these requirements. At the same time, 5G wireless is expected to extend to frequency-range-of-operation beyond 10 GHz and into the mmw range. The corresponding smaller wave length will be an enabler of more advanced antenna configurations with a much larger number of controllable antenna elements compared to the antenna configurations of today. In this paper we discuss advanced antenna solutions for 5G wireless access, what are the opportunities, alternatives, and possible obstacles.
