Performance Evaluation of Scheduling in 5G-mmWave Networks under Human Blockage (2020)

The millimetre-wave spectrum provisions enormous enhancement to the achievable data rate of 5G networks. However, human blockages affecting the millimetre-wave signal can severely degrade the performance if proper resource allocation is not considered. In this paper, we assess how conventional schedulers, such as the Proportional Fair scheduler, react to the presence of blockage. Our results show that the resource allocation may disfavour users suffering from blockage, leading to low data rate for those users. To circumvent this problem, we show that the data rate of those users can be improved by using a scheduler adapted to react to upcoming blockage events. The adapted scheduler aims at proactively allocating the resources before a blockage happens, mitigating losses. Such adaptation is motivated by recent progress in blockage prediction for millimetre-wave signals in a dynamic human blockage scenario. Our extensive simulations indicate gains in the 1st percentile rate and fairness with respect to Proportional Fair scheduler when blockage conditions are severe.
Performance of railway track circuit codes with burst interference (2002)

The data capacity of railway track circuits can be increased by the use of binary block codes. A comma-free coding scheme suitable for railway track circuit data is presented which out performs the other comma-free code construction in terms of synchronisation in Gaussian noise. However, the interference encountered in a railway environment is likely to be impulsive and bursty rather than Gaussian. Simulation results of the (31,11) BCH coset code modulated by non-coherent FSK are presented, using an impulsive interference model which more accurately represents typical railway noise.
Intuition: Inferential Heuristic or Epistemic Mode? (1987)

This study attempts to evaluate psychological concepts of intuition. Of the many definitions of intuition, two extremes emerge. One holds intuition to be an inferential heuristic, and the other defines it as a cognitive mode capable of immediate, non-inferential, holistic processing. Three inventories were administered that purport to measure intuition. The Intuitive Problem Solving Scale corresponds to the definition of intuition as inferential heuristic. The Psycho-Epistemological Profile and the Meyers-Briggs Type Indicator define intuition as a non-inferential epistemic mode. Scores on these scales are correlated with scores on various inferential tasks, as well as with scores on measures of three traits usually associated with intuition (originality, private self-awareness, and creativity). Results indicate that intuition is not completely reducible to inference.
Synthesis of novel 3‐alkoxy‐ and 3‐alkylthioindole and ‐benzofuran‐2‐carboxamides (1996)

Abstract The preparation of a series of 3,5‐substituted indole‐ and benzofuran‐2‐carboxamides is described. A 3‐alkoxy‐5‐hydroxybenzofuran was prepared by elaboration of a benzyloxy salicylate ester. A related 3‐alkylthiobenzofuran was obtained by the addition of thionyl chloride and isopropylmagnesium chloride to a benzofuran ester. A series of 3‐(methylthio)indoles was prepared from an indole sulfonium salt intermediate.
Replication of DNA Microarrays from Zip Code Masters (2006)

This report describes a mechanical method for efficient and accurate replication of DNA microarrays from a zip code master. The zip code master is a DNA array that defines the location of oligonucleotides consisting of two parts: a code sequence, which is complementary to one or more of the zip codes, and the functional sequence, which is terminated with biotin. Following hybridization of the zip code to the code sequence, a replica surface functionalized with streptavidin is brought into conformal contact with the surface of the master. When the two surfaces are separated, the functional and code sequences are transferred to the replica, and the zip code remains on the surface of the master. Using this approach it is possible to prepare replica arrays having any configuration from a single, universal master array. Here we demonstrate that this approach can be used to replicate master arrays having up to three different sequences, that feature sizes as small as 100 microm can be replicated, and that master arrays can be used to prepare multiple replicas.
Is liver transplantation a risk factor for cardiovascular disease? a meta-analysis of observational studies (2012)

Up to two-thirds of patients develop metabolic syndrome within the first 5 years after orthotopic liver transplantation (OLT). However, data on overall cardiovascular (CV) morbidity and mortality among OLT recipients and particularly those who develop metabolic syndrome remain elusive. A literature search using MEDLINE, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and meeting abstracts (along with their bibliographies) was performed to identify studies. Data on ischemic CV events were extracted from each study and were used for pooled analyses. Overall pooled estimates and 95% confidence intervals (CIs) for the incidence of CV events and deaths were obtained with a random effects model. Twelve observational studies reporting CV outcomes for 4792 post-OLT recipients who were followed for 28,783 person-years were included. Pooled estimates showed that the 10-year risk of developing CV events among the post-OLT recipients was 13.6% (95% CI = 9%-8.1%). Pooled estimates from case-control studies showed that the post-OLT group had an approximately 64% greater risk of experiencing CV events than controls (standardized incidence ratio = 1.64, 95% CI = 1.18-2.20). Among OLT recipients, those with metabolic syndrome were approximately 4 times more likely to have a CV event [odds ratio (OR) = 4.01, 95% CI = 1.94-8.32] without any significant increase in all-cause mortality (OR = 1.15, 95% CI = 0.63-2.10). In conclusion, this systematic review suggests that OLT recipients and particularly those with metabolic syndrome have a high risk for CV events. However, the literature is limited and lacks high-quality studies. Future prospective studies are warranted to confirm these findings and determine whether aggressive risk-reduction strategies can attenuate the increased CV risk seen in this population.
Multicenter prospective clinical study to evaluate the prediction of short-term outcome in pregnant women with suspected preeclampsia (PROGNOSIS): study protocol (2014)

The results of PROGNOSIS will provide the most comprehensive evidence to date on the accuracy of the sFlt-1/PlGF ratio for short-term prediction of preeclampsia/eclampsia/HELLP syndrome. Adoption of the sFlt-1/PlGF test in clinical practice has the potential to reduce the frequency of adverse pregnancy outcomes for both mother and fetus, and decrease healthcare costs associated with unnecessary hospitalization of women with suspected preeclampsia.

Absolute distance measurement in a combined-dispersive interferometer using a femtosecond pulse laser (2015)

In this paper, a ranging system using dispersive interferometry is developed with a femtosecond pulse laser, aiming to eliminate the measurement dead zones by using a greatly unbalanced Mach–Zehnder interferometer. The distance can be measured by the frequency of the spectral modulation. We indicate that the integer number of the pulse-to-pulse length can be determined by changing the repetition frequency. In the short distance measurement, the results show an agreement within 1.5 μm compared with an incremental He-Ne laser in the 1 m measurement range. We do large-scale experiments on a long optical rail using a typical Michelson interferometer, and an agreement well within 25 μm is obtained in a range up to 75 m, corresponding to a relative precision of 3.3 × 10−7. Additionally, we experimentally optimize the system set-up to minimize the measurement uncertainty.
Provisioning of application modules to Android devices (2015)

The Google Android platform supports provisioning of packaged applications to an Android device. However, an existing approach requires user's interaction during the installation of a new application or its modules. We present a new approach to dynamic modules loading which enables provisioning of new modules to Android device dynamically without the interaction with the user. It will allow complex applications to adapt to the surrounding conditions and requirements of the user by downloading additional code from a server or a neighboring peer device. In our solution we propose to replace the default application class-loader with a custom one while employing some existing mechanisms of class-loading from APK packages at the Android platform.

Novel tactics for designing water-soluble molecules in drug discovery (2014)

From a strategic point of view, improving the solubility of a compound should be straightforward because it can be accomplished by simply reducing hydrophobicity or crystalline stability. However, the structural elements and physical properties which control solubility also influence potency, pharmacokinetics and toxicity. Furthermore, there are practical aspects such as the quantity and quality of solubility-related data, which hamper the development of structure-solubility relationships. Given that poor aqueous solubility remains a primary issue in drug discovery, there is a continuous need for novel methods to overcome it.

A systemic resistance inducing antiviral protein with N-glycosidase activity from Bougainvillea xbuttiana leaves. (2001)

An antiviral protein from Bougainvillea xbuttiana leaves induced systemic resistance in host plants N. glutinosa and Cyamopsis tetragonoloba against TMV and SRV, respectively which was reversed by actinomycin D, when applied immediately or shortly after antiviral protein treatment. When the inhibitor was applied to the host plant leaves post inoculation, it was effective if applied upto 4 h after virus infection. It also delayed the expression of symptoms in systemic hosts of TMV. The inhibitor showed characteristic N-glycosidase activity on 25S rRNA of tobacco ribosomes, suggesting that it could also be interfering with virus multiplication through ribosome-inactivation process.
Simplified Method for Dissolved DNA Determination in Aquatic Environments (1986)

A method was developed for the determination of dissolved DNA in aquatic environments. The method is based upon the concentration of dissolved DNA by ethanol precipitation of 0.2-mum-pore-size filtered water. The DNA in concentrated extracts was quantified by the fluorescence of Hoechst 33258-DNA complexes. Fluorescence not attributable to DNA was corrected for by DNase I digestion of the extracts and averaged 25% of the total fluorescence for all samples. The effectiveness of the procedure for concentrating dissolved DNA was demonstrated by the efficient (>90%) recovery of internal standards. Concentrations of dissolved DNA from a variety of marine and freshwater environments ranged from 0.2 to 44 mug/liter, with the highest values being obtained for estuarine and river environments. The method is simple, specific for DNA, and more sensitive than previously described methods for the determination of extracellular DNA.
Analysis Methods in Neural Language Processing: A Survey (2019)

Abstract The field of natural language processing has seen impressive progress in recent years, with neural network models replacing many of the traditional systems. A plethora of new models have been proposed, many of which are thought to be opaque compared to their feature-rich counterparts. This has led researchers to analyze, interpret, and evaluate neural networks in novel and more fine-grained ways. In this survey paper, we review analysis methods in neural language processing, categorize them according to prominent research trends, highlight existing limitations, and point to potential directions for future work.
Neural Architecture Search without Training (2020)

The time and effort involved in hand-designing deep neural networks is immense. This has prompted the development of Neural Architecture Search (NAS) techniques to automate this design. However, NAS algorithms tend to be slow and expensive; they need to train vast numbers of candidate networks to inform the search process. This could be alleviated if we could partially predict a network's trained accuracy from its initial state. In this work, we examine the overlap of activations between datapoints in untrained networks and motivate how this can give a measure which is usefully indicative of a network's trained performance. We incorporate this measure into a simple algorithm that allows us to search for powerful networks without any training in a matter of seconds on a single GPU, and verify its effectiveness on NAS-Bench-101, NAS-Bench-201, NATS-Bench, and Network Design Spaces. Our approach can be readily combined with more expensive search methods; we examine a simple adaptation of regularised evolutionary search. Code for reproducing our experiments is available at https://github.com/BayesWatch/nas-without-training.

Accelerating Matrix Processing for MIMO Systems (2021)

Massive Multiple In and Multiple Out (MIMO) is being used in the fifth generation of wireless communication systems. As the number of antennas increases, the computational complexity grows dramatically, and this involves matrix calculations with complex numbers. We have designed and implemented a general matrix arithmetic processor to accelerate these calculations, including matrix multiplication, Singular Value Decomposition (SVD), and QR decomposition, on an FPGA. The design can be implemented in fixed-point or single-precision floating-point depending on the requirements of the application. The system behavior can be controlled by instructions such as elementary multiplication, rotation and vector projection, which allows the system to work as a coprocessor in a baseband System on a Chip (SoC). Latency for changing from one matrix computation to another is just a few clock cycles, providing the low latency required for edge processing. The design is implemented and verified on the Xilinx RFSoC development board using fixed point and single precision floating point numbers and matrix sizes of 8 × 8 and 16 × 16.
Rotavirus diversity and evolution in the post-vaccine world. (2012)

Rotaviruses (RVs) are a large genetically diverse population of segmented double-stranded (ds) RNA viruses that are important causes of gastroenteritis in many animal species. The human RVs are responsible for the deaths of nearly 450,000 infants and young children each year, most occurring in developing countries. Recent large-scale sequencing efforts have revealed that the genomes of human RVs typically consist of phylogenetically linked constellations of eleven dsRNA segments. The presence of such preferred constellations indicate that the human RV genes have co-evolved to produce protein sets that work optimally together to support virus replication. Two of the viral genes encode virion outer capsid proteins (VP7 and VP4) whose antigenic properties define the G/P type of the virus. From year-to-year and place-to-place, the G/P type of human RVs associated with disease can fluctuate dramatically, phenomena that can be associated with the presence and behavior of genetically distinct RV clades. The recent introduction of two live attenuated RV vaccines [RotaTeq (TM) and Rotarix (TM)] into the childhood vaccination programs of various countries has been highly effective in reducing the incidence of RV diarrheal disease. Whether the widespread use of these vaccines will introduce selective pressures on human RVs, triggering genetic and antigenic changes that undermine the effectiveness of vaccinations programs, is uncertain and will require continued surveillance of human RVs.
Effect of glutaraldehyde on hemoglobin: functional aspects and Mössbauer parameters (1986)

Glutaraldehyde is widely used for the cross-linking of hemoglobin for blood substitute research or for technological purposes. The effects of this reagent on the biochemical properties of hemoglobin were correlated with Mössbauer data. Human hemoglobin was cross-linked by glutaraldehyde as soluble polymers and insoluble particles. Effects of cross-linking on oxygen affinity, oxidation-reduction potential, autoxidation kinetics, and thermal stability were studied. Stability of cross-linked hemoglobin was specifically studied by Mössbauer spectroscopy. Oxygen affinity is increased, redox potential is decreased, autoxidation rates are increased, and stability towards thermal denaturation is increased. The regeneration of partially denatured hemoglobin by glutaraldehyde cross-linking is shown. Effects of cross-linking on biochemical properties are explained by the hypothesis of the opening of the heme pocket on the distal-histidine side and the concomitant charge transfer from the iron to the oxygen.
Determination of serum organic acids in puppies with naturally acquired parvoviral enteritis. (2002)

The purpose of the present study was to investigate the acid-base status and the serum concentration of organic acids in puppies with naturally occurring canine parvoviral enteritis. Between July 1999 and July 2000, 25 client-owned puppies admitted to the St. Louis Animal Emergency Clinic South for treatment of enteritis caused by parvovirus infection were used in our study. Control blood samples were collected from 22 healthy puppies less than 9 months of age. Serum organic acid concentrations were quantitatively determined by HPLC. Puppies infected with parvovirus had significantly lower plasma concentrations of sodium, potassium, chloride, and bicarbonate than controls. Although serum L-lactate tended to increase in some puppies with canine parvoviral enteritis, our study demonstrated that most affected puppies developed only mild compensated metabolic acidosis. None of the affected puppies had an elevated serum D-lactate concentration at admission.
ApoE4-Induced Cholesterol Dysregulation and Its Brain Cell Type-Specific Implications in the Pathogenesis of Alzheimer's Disease. (2019)

Significant knowledge about the pathophysiology of Alzheimer's disease (AD) has been gained in the last century; however, the understanding of its causes of onset remains limited. Late-onset AD is observed in about 95% of patients, and <i>APOE4</i>-encoding apolipoprotein E4 (ApoE4) is strongly associated with these cases. As an apolipoprotein, the function of ApoE in brain cholesterol transport has been extensively studied and widely appreciated. Development of new technologies such as human-induced pluripotent stem cells (hiPSCs) and CRISPR-Cas9 genome editing tools have enabled us to develop human brain model systems <i>in vitro</i> and readily manipulate genomic information. In the context of these advances, recent studies provide strong evidence that abnormal cholesterol metabolism by ApoE4 could be linked to AD-associated pathology. In this review, we discuss novel discoveries in brain cholesterol dysregulation by ApoE4. We further elaborate cell type-specific roles in cholesterol regulation of four major brain cell types, neurons, astrocytes, microglia, and oligodendrocytes, and how its dysregulation can be linked to AD pathology.
Real-Time Multi-View Facial Capture with Synthetic Training (2017)

We present a real-time multi-view facial capture system facilitated by synthetic training imagery. Our method is able to achieve high-quality markerless facial performance capture in real-time from multi-view helmet camera data, employing an actor specific regressor. The regressor training is tailored to specified actor appearance and we further condition it for the expected illumination conditions and the physical capture rig by generating the training data synthetically. In order to leverage the information present in live imagery, which is typically provided by multiple cameras, we propose a novel multi-view regression algorithm that uses multi-dimensional random ferns. We show that higher quality can be achieved by regressing on multiple video streams than previous approaches that were designed to operate on only a single view. Furthermore, we evaluate possible camera placements and propose a novel camera configuration that allows to mount cameras outside the field of view of the actor, which is very beneficial as the cameras are then less of a distraction for the actor and allow for an unobstructed line of sight to the director and other actors. Our new real-time facial capture approach has immediate application in on-set virtual production, in particular with the ever-growing demand for motion-captured facial animation in visual effects and video games.
Disruptive Change in the Taxi Business: The Case of Uber (2016)

In most cities, the taxi industry is highly regulated and has restricted entry. Ride sharing services, such as Uber and Lyft, which use mobile internet technology to connect passengers and drivers, have begun to compete with traditional taxis. This paper examines the efficiency of ride sharing services vis-a-vis taxis. In most cities with data available, UberX drivers spend a significantly higher fraction of their time, and drive a substantially higher share of miles, with a passenger in their car than do taxi drivers. Reasons for this efficiency advantage are explored.
