Advances in quantum light emission from 2D materials (2018)

Abstract Two‐dimensional (2D) materials are being actively researched due to their exotic electronic and optical properties, including a layer‐dependent bandgap, a strong exciton binding energy, and a direct optical access to electron valley index in momentum space. Recently, it was discovered that 2D materials with bandgaps could host quantum emitters with exceptional brightness, spectral tunability, and, in some cases, also spin properties. This review considers the recent progress in the experimental and theoretical understanding of these localized defect‐like emitters in a variety of 2D materials as well as the future advantages and challenges on the path toward practical applications.
MLIR: A Compiler Infrastructure for the End of Moore's Law (2020)

This work presents MLIR, a novel approach to building reusable and extensible compiler infrastructure. MLIR aims to address software fragmentation, improve compilation for heterogeneous hardware, significantly reduce the cost of building domain specific compilers, and aid in connecting existing compilers together. MLIR facilitates the design and implementation of code generators, translators and optimizers at different levels of abstraction and also across application domains, hardware targets and execution environments. The contribution of this work includes (1) discussion of MLIR as a research artifact, built for extension and evolution, and identifying the challenges and opportunities posed by this novel design point in design, semantics, optimization specification, system, and engineering. (2) evaluation of MLIR as a generalized infrastructure that reduces the cost of building compilers-describing diverse use-cases to show research and educational opportunities for future programming languages, compilers, execution environments, and computer architecture. The paper also presents the rationale for MLIR, its original design principles, structures and semantics.

A Multi-User Receiver for PUCCH LTE FORMAT 1 in Non-Cooperative Multi-Cell Architectures (2010)

In this paper, we propose a new multi-user receiver processing for PUCCH LTE that counteracts the ICI in a non-cooperative multi-cell architecture. Using the fact that the received signal in PUCCH signaling follows a constrained tensor model, a multi-user receiver based on an iterative joint channel/code estimation and symbol detection is proposed. The interest in such a challenging setting relies on the overhead reduction among neighboring cells. Simulation results show remarkable performance gains of the proposed receiver compared to the conventional time-frequency decorrelator based receiver under the same conditions. We also show a performance comparison with the cooperative version of such a tensor receiver.
Limits on the AnomalousZZγandZγγCouplings inpp¯Collisions ats=1.8TeV (1995)

We performed a direct search for the anomalous $\mathrm{ZZ}\ensuremath{\gamma}$ and $Z\ensuremath{\gamma}\ensuremath{\gamma}$ couplings by studying $p\overline{p}\ensuremath{\rightarrow}\ensuremath{\ell}\ensuremath{\ell}\ensuremath{\gamma}+X$ $(\ensuremath{\ell}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}e,\ensuremath{\mu})$ events at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8$ TeV with the D0 detector at the Fermilab Tevatron Collider. A fit to the transverse energy spectrum of the photon in the signal events, based on the data set corresponding to an integrated luminosity of $14.3{\mathrm{pb}}^{\ensuremath{-}1}$ ( $13.7{\mathrm{pb}}^{\ensuremath{-}1}$) for the electron (muon) channel, yields the following $95%$ confidence level limits on the anomalous $\mathrm{CP}$-conserving $\mathrm{ZZ}\ensuremath{\gamma}$ couplings: $|{h}_{30}^{Z}|&lt;1.8$ ( ${h}_{40}^{Z}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0$) and $|{h}_{40}^{Z}|&lt;0.5$ ( ${h}_{30}^{Z}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0$), for a form-factor scale $\ensuremath{\Lambda}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}500$ GeV. Limits for the $Z\ensuremath{\gamma}\ensuremath{\gamma}$ couplings and $\mathrm{CP}$-violating couplings are also discussed.

HIV appears to be a marker of behavioral or family-related risk factors that affect the incidence of HNC in HIV patients.
Nucleotide sequence analysis of two simian virus 40 mutants with deletions in the late region of the genome (1979)

Two mutants of simian virus 40, dl-1261 and dl-1262, have deletions that map between coordinated 0.90 and 0.95 (Cole et al., J. Virol 24:277--294, 1977). Both affect the structure of the two minor proteins VP2 and VP3. The precise location and size of the deletions have now been determined by nucleotide sequence analysis. Mutant dl-1261 is deleted of 54 base pairs, is temperature sensitive for the protein defined by the D complementation group, and promotes the synthesis of shorter VP2 and VP3 polypeptides. Mutant dl-1262 is viable irrespective of temperature and has a deletion of 36 base pairs, 23 of which overlap the deletion in dl-1261. Since these mutants produce normal VP1, the deleted regions probably have no function in the splicing of precursor RNA to the VP1 mRNA.
Differential dependency of unmyelinated and A delta epidermal and upper dermal innervation on neurotrophins, trk receptors, and p75LNGFR. (1998)

The impact of the nerve growth factor (NGF) family of neurotrophins and their receptors was examined on the cutaneous innervation in the mystacial pads of mice. Ten sets of unmyelinated and thinly myelinated sensory and autonomic innervation were evaluated that terminated in the epidermis, upper dermis, and upper part of the intervibrissal hair follicles. Mystacial pads were analyzed from newborn to 4-week-old mice that had homozygous functional deletions of the genes for NGF, brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), neurotrophin-4 (NT-4), tyrosine kinase (trk) A, trkB, trkC, or p75. Mystacial pads were also analyzed in adult transgenic mice that had overproduction of NGF, BDNF, or NT-3 driven by a keratin promoter gene. The innervation was revealed by using immunofluorescence and immunocytochemistry with antibodies for protein gene product (PGP) 9.5, calcitonin gene-related product (CGRP), substance P (SP), galanin (GAL), neuropeptide Y (NPY), tyrosine hydroxylase (TH), and a neurofilament protein. The cumulative results indicated that NGF/trkA signaling plays a major role in the outgrowth and proliferation of sensory axons, whereas NT-3/ trkA signaling plays a major role in the formation of sensory endings. TrkC is also essential for the development of three sets of trkA-dependent sensory innervation that coexpress CGRP, SP, and GAL. Another set of sensory innervation that only coexpressed CGRP and SP was solely dependent upon NGF and trkA. Surprisingly, most sets of trkA-dependent sensory innervation are suppressed by trkB perhaps interacting with p75. BDNF and NT-4 appear to mediate this suppressing effect in the upper dermis and NT-4 in the epidermis. In contrast to sensory innervation, sympathetic innervation to the necks of intervibrissal hair follicles depends upon NGF/trkA signaling interacting with p75 for both the axon outgrowth and ending formation. Although NT-3/trkA signaling is essential for the full complement of sympathetic neurons, NT-3 is detrimental to the formation of sympathetic terminations to the necks of hair follicles. TrkB signaling mediated by BDNF but not NT-4 also suppresses these sympathetic terminations. One sparse set of innervation, perhaps parasympathetic, terminating at the necks of hair follicles is dependent solely upon NT-3 and trkC. Taken together, our results indicate that the innervation of the epidermis, upper dermis, and the upper portion of hair follicles is regulated by a competitive balance between promoting and suppressing effects of the various neurotrophins.
Innovative practices session 1C: Innovative practices in RF test (2010)

Test costs continue to rise as designs become more complex, the controllability and observability points at the chip boundary reduce, defects become more subtle making it harder to detect them, and reliability requirements become stringent. While several techniques have been developed and deployed to contain test costs to remain within acceptable limits, new technologies tend to generate excursions where the costs once again become prominent. Digital circuits have benefitted from structured test methodologies (involving DFT, ATPG and BIST) wherein different optimizations have been incorporated to reduce test costs. Analog circuits have also received wide attention due increasing analog content in today's chips. DFT techniques for them have evolved to provide additional controllability and observability through additional on-chip / off-chip instrumentation. Digitization of the analog stimuli and response have also been considered adequate to ascertain the correctness of analog circuits. RF circuits, on the other hand, have a few characteristics which have rendered such simplification so far inadequate. (i) The stimuli and response can be greatly deformed due to attenuation at the high frequencies at which the transmission occurs over the tester channels. (ii) Multiple RF modules in a chip cause further interference, thereby impairing the measurement resolution attainable for test. (iii) While on-chip instrumentation for test and measurement is even more important, providing it itself largely uneconomical. (iv) There is virtually little automation (EDA tools, etc.) available today to address these issues. Hence, though RF circuits are just an extension of analog / mixed-signal circuits in the high frequency range, their test poses several new challenges, which have hitherto not been adequately solved.
RECONSTRUCTION OF BIOCHEMICAL NETWORKS (2006)

Cellular functions rely on the interactions of their chemical constituents. Various high-throughput experimental methods allow us now to determine the chemical composition of cells on a genome scale. These methods include whole genome sequencing and annotation (genomics), the measurement of the messenger RNA molecules that are synthesized under a given condition (transcriptomics), the protein abundance, interactions and functional states (proteomics) measurements of the presence and concentration of metabolites (metabolomic), and metabolic fluxes (fluxomics). In addition, methods now exist to determine the binding sites of protein to the DNA (location analysis) and to measure of a limited number of fluxes through reactions inside a cell. The physical location of protein products and segments of the DNA can be determined using various fluorescent reporting molecules. All these methods can be used to help to reconstruct the biochemical reaction networks that operate in cells. This part of the text discusses the reconstruction of metabolic, regulatory, and signaling networks. Given the rate at which new methods are being developed, it is likely that this part of the text will become dated the fastest. However, with new or existing methods the result of the reconstruction process is a set of chemical reactions or interactions that comprise these networks. The reader should be mindful of the fact that these are not separate and independent networks. In fact they interact with one another.

Evaluation of ALE processes for patterning (2016)

The need for continued device scaling along with the increasing demand for high precision have lead to the development of atomic layer etch processes in semiconductor manufacturing. We have tested this new methodology with regard to patterning applications. While these new plasma-enhanced atomic layer etch (PE-ALE) processes show encouraging results, most patterning applications are best realized by optimizations through discharge chemistry and/or plasma parameters. While PE-ALE approaches seem to have limited success for trilayer patterning applications, significant improvements were obtained when applying them to small pitch. In particular the increased selectivity to OPL seems to offer a potential benefit for patterning high aspect ratio features.
Finding corresponding points based on Bayesian triangulation (1996)

In this paper, we consider the problems of finding corresponding points from multiple perspective projection images (the correspondence problem), and estimating the 3-D point from which these points have arisen (the triangulation problem). We pose the triangulation problem as that of finding the Bayesian maximum, a posteriori estimate of the 3-D point, given its projections in N images, assuming a Gaussian error model for the image point co-ordinates and the camera parameters. We solve this by an iterative steepest descent method. We then consider the correspondence problem as a, statistical hypothesis verification problem. Given a set of 2-D points, under the hypothesis that the points are in correspondence, the MAP estimate of the 3-D point is computed. Based on the MAP estimate, we derive a statistical test for verifying this hypothesis. To find sets of corresponding points when multiple points in each of N images are given, we propose a method that does the Bayesian triangulation and hypothesis verification on each N-tuple of points, selecting those that pass the hypothesis test. We characterize the performance of the Bayesian triangulation in terms of the average distance of the triangulated 3-D point from the true 3-D point, and of the point correspondence method in terms of its misdetection and false alarm rates.
Scaled Self-Aligned N-Polar GaN/AlGaN MIS-HEMTs With $f_{T}$ of 275 GHz (2012)

In this letter, we demonstrate state-of-the-art performance from N-polar GaN/AlGaN metal-insulator-semiconductor high-electron-mobility transistors. Self-aligned gate-first process was used for the fabrication of transistors. Graded InGaN and InN contact layers were used to achieve low ohmic contact resistance. The GaN channel thickness was scaled to 7 nm from previous generation of N-polar GaN devices to improve the aspect ratio and hence achieve better small-signal performance.

HVLearn: Automated Black-Box Analysis of Hostname Verification in SSL/TLS Implementations (2017)

SSL/TLS is the most commonly deployed family of protocols for securing network communications. The security guarantees of SSL/TLS are critically dependent on the correct validation of the X.509 server certificates presented during the handshake stage of the SSL/TLS protocol. Hostname verification is a critical component of the certificate validation process that verifies the remote server's identity by checking if the hostname of the server matches any of the names present in the X.509 certificate. Hostname verification is a highly complex process due to the presence of numerous features and corner cases such as wildcards, IP addresses, international domain names, and so forth. Therefore, testing hostname verification implementations present a challenging task. In this paper, we present HVLearn, a novel black-box testing framework for analyzing SSL/TLS hostname verification implementations, which is based on automata learning algorithms. HVLearn utilizes a number of certificate templates, i.e., certificates with a common name (CN) set to a specific pattern, in order to test different rules from the corresponding specification. For each certificate template, HVLearn uses automata learning algorithms to infer a Deterministic Finite Automaton (DFA) that describes the set of all hostnames that match the CN of a given certificate. Once a model is inferred for a certificate template, HVLearn checks the model for bugs by finding discrepancies with the inferred models from other implementations or by checking against regular-expression-based rules derived from the specification. The key insight behind our approach is that the acceptable hostnames for a given certificate template form a regular language. Therefore, we can leverage automata learning techniques to efficiently infer DFA models that accept the corresponding regular language. We use HVLearn to analyze the hostname verification implementations in a number of popular SSL/TLS libraries and applications written in a diverse set of languages like C, Python, and Java. We demonstrate that HVLearn can achieve on average 11.21% higher code coverage than existing black/gray-box fuzzing techniques. By comparing the DFA models inferred by HVLearn, we found 8 unique violations of the RFC specifications in the tested hostname verification implementations. Several of these violations are critical and can render the affected implementations vulnerable to active man-in-the-middle attacks.
36-Month Evaluation of Intravitreous Aflibercept Injection for Wet Age-Related Macular Degeneration in Patients Previously Treated With Ranibizumab or Bevacizumab (2018)

Despite the significant visual and anatomical gains observed in the 2 years of fixed-dosing IAI, there was gradual decline in these improvements when patients were transitioned to a variable regimen. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:179-185.].
Decreased intracellular calcium mediates the histamine H 3 -receptor-induced attenuation of norepinephrine exocytosis from cardiac sympathetic nerve endings (2001)

Activation of presynatic histamine H(3) receptors (H(3)R) down-regulates norepinephrine exocytosis from cardiac sympathetic nerve terminals, in both normal and ischemic conditions. Analogous to the effects of alpha(2)-adrenoceptors, which also act prejunctionally to inhibit norepinephrine release, H(3)R-mediated antiexocytotic effects could result from a decreased Ca(2+) influx into nerve endings. We tested this hypothesis in sympathetic nerve terminals isolated from guinea pig heart (cardiac synaptosomes) and in a model human neuronal cell line (SH-SY5Y), which we stably transfected with human H(3)R cDNA (SH-SY5Y-H(3)). We found that reducing Ca(2+) influx in response to membrane depolarization by inhibiting N-type Ca(2+) channels with omega-conotoxin (omega-CTX) greatly attenuated the exocytosis of [(3)H]norepinephrine from both SH-SY5Y and SH-SY5Y-H(3) cells, as well as the exocytosis of endogenous norepinephrine from cardiac synaptosomes. Similar to omega-CTX, activation of H(3)R with the selective H(3)R-agonist imetit also reduced both the rise in intracellular Ca(2+) concentration (Ca(i)) and norepinephrine exocytosis in response to membrane depolarization. The selective H(3)R antagonist thioperamide prevented this effect of imetit. In the parent SH-SY5Y cells lacking H(3)R, imetit affected neither the rise in Ca(i) nor [(3)H]norepinephrine exocytosis, demonstrating that the presence of H(3)R is a prerequisite for a decrease in Ca(i) in response to imetit and that H(3)R activation modulates norepinephrine exocytosis by limiting the magnitude of the increase in Ca(i). Inasmuch as excessive norepinephrine exocytosis is a leading cause of cardiac dysfunction and arrhythmias during acute myocardial ischemia, attenuation of norepinephrine release by H(3)R agonists may offer a novel therapeutic approach to this condition.
Angular dependence of sampling MTF (1997)

Sampling MTF defined in Park, Hock, and de Luca, as an x and y sampling, can be generalized for image data not along x and y directions. For a given sampling lattice (such as in a laser printer, a scene projector, or a focal plane array), we construct a two-dimensional sampling MTF based on the distance between nearest samples in each direction. Because the intersample distance depends on direction, the sampling MTF will be best in the directions of highest spatial sampling, and poorer in the directions of sparse sampling. We compare hexagonal and rectangular lattices in terms of their equivalent spatial frequency bandwidth. We filter images as demonstration of the angular-dependent two-dimensional sampling MTF.
Toward a Personalized Medicine Approach to the Management of Inflammatory Bowel Disease (2014)

The medical management of inflammatory bowel disease (IBD) is evolving toward a personalized medicine-based model. Modern therapeutic algorithms that feature use of tumor necrosis factor (TNF) antagonists in combination with immunosuppressive are highly effective when initiated in high-risk patients early in the course of disease. Defined targets that guide intensification of therapy are critical interventions. In this model, therapy is optimized through appropriate pretreatment testing, therapeutic drug monitoring, and patient-based monitoring strategies. This review discusses the current application of personalized medicine to the management of IBD.
Incentive networks (2005)

We propose a notion of incentive networks, modeling online settings in which multiple participants in a network help each other find information. Within this general setting, we study query incentive networks, a natural abstraction of question-answering systems with rewards for finding answers. We analyze strategic behavior in such networks and under a simple model of networks, show that the Nash equilibrium for participants' strategies exhibits an unexpected threshold phenomenon.
