Integer-Forcing Linear Receivers: A New Low-Complexity MIMO Architecture (2010)

We propose a new framework for MIMO decoding based on a recently developed technique for reliably conveying linear equations over wireless channels. Each transmit antenna sends an independent data stream using the same linear code. As a result, any integer combination of the codewords is itself a codeword. Each receive antenna observes a random complex-valued combination of the codewords according to the fading coefficients. We use a linear pre-processing step at the receiver to transform the effective channel into a (full-rank) integer matrix. A single stream decoder is then used to recover integer combinations of the codewords. These equations of codewords are then translated into equations of the transmitted data streams over a finite field which can be easily solved for the original data. We examine the performance of our scheme in terms of the probability of outage and show that significant gains are possible over standard linear architectures for both i.i.d. and correlated Rayleigh fading.
Light source for gravitational wave detector (1996)

For the detection of gravitational wave using Michelson-type interferometers a strain sensitivity of at least 10-21 is desired. To reach this sensitivity, the lasers light source has to work at high power levels in single-frequency operation (tens of Watts) with excellent frequency stability (FM-noise <3.107 Hz/√VHz), and intensity noise as close as possible to the quantum noise limit. Beyond that, the lifetime of these systems must be in the range of several 10,000h at low operational costs.
PROCESSES FOR PRODUCING BEER WITH A LOW TENDENCY TO FORM HAZE (1968)

It was confirmed that wort from malt resteeped in a solution of formaldehyde (1000 mg./litre), had a low level of anthocyanogens. It was shown that beer brewed from this malt had a lesser tendency to form haze than beer brewed from a malt resteeped in water. Malt yielding wort with usefully reduced levels of anthocyanogens could be prepared by adding formaldehyde (500–1000 mg./litre), to the final steep, in an otherwise conventional malting sequence. The rapid rate of haze formation that occurred in beers to which formalin had been added was shown to be a useful, quick guide to their stability under different storage conditions. When hydrogen peroxide (100 mg./litre) mashing liquor was added to mashes it reduced the anthocyanogen levels of the wort. The beers prepared from treated mashes were remarkably slow to form haze. The effect was greatest when hydrogen peroxide was added in small increments throughout the mashing period. The other alterations in wort characteristics resulting from this process, including marginal increases in colour and decreases in fermentability, were small. In most trials the treatment did not significantly alter the flavour of the beer. Charcoal (Norit, N.K.), added to the mash (500 mg./kg. grist), or to the copper (500 mg./kg. grist), reduced the anthocyanogen contents of the worts; the final beers had greatly enhanced shelf-lives. Charcoal was most effective when spread over the surface of the mash at the start of sparging.

Privacy-Preserving RFID Systems: Model and Constructions. (2010)

In this paper, we study systems where a reader wants to authenticate and identify legitimate RFID tags. Such system needs thus to be correct (legitimate tags are accepted) and sound (fake tags are rejected). Moreover, an RFID tag in a privacy-preserving system should be anonymous and untraceable, except for the legitimate reader. We here present the first security model for RFID authentication/identification privacypreserving systems which is at the same time complete and easy to use. Our correctness property permits to take into account active adversaries. Our soundness property incorporates the case of adversaries realizing relay attacks. Finally, our privacy model includes adversaries with no restrictions on their interactions with the system and moreover takes into account the case of “future correlations”. We next propose several constructions, based on the work from Vaudenay, proving that (i) our strongest property is at least as strong as those of Vaudenay
Status of ion implantation doping and isolation of III-V nitrides (1995)

Ion implantation doping and isolation has played a critical role in the realization of high performance photonic and electronic devices in all mature semiconductor material systems. This is also expected to be the case for the binary III-V nitrides (InN, GaN, and AlN) and their alloys as the epitaxial material quality improves and more advanced device structures are fabricated. With this in mind, we review the status of implant doping and isolation of GaN and the ternary alloys AlGaN, InGaN, and InAlN. In particular, we reported on the successful n- and p-type doping of GaN by ion implantation of Mg+P and Si, respectively, and subsequent high temperature rapid thermal anneals in excess of 1000{degrees}C. In the area of implant isolation, N-implantation has been shown to compensate both n- and p-type GaN, N and O-implantation effectively compensates InAlN, and InGaN shows limited compensation with either N or F implantation.
Diamination Reactions of Trichloromethyl-s-triazines with Aliphatic Amines (1970)

A series of 2-alkyl-4, 6-unsym. diamino-s-triazines has been synthesized in order to determine the effect on nitrification inhibitory and herbicidal activities of introducing two different amino groups on alkyl-s-triazines ring. The synthetic method involves the reaction of 2-alkyl-4, 6-bis (trichloromethyl) -s-triazines with an aliphatic amine or ammonia to give 2-alkyl-4-alkylamino (or amino) -6-trichloromethyl-s-triazines, which are then condensed with another amine or ammonia. In the preparation of 2-alkyl-4-alkylamino-6-amino-s-triazines, the use of dimethylformamide as solvent gave good results.
Research on the growth of dye film in vacuum in situ (2008)

Organic film deposition in vacuum is fast developing scientific and industrial domain. We developed installation for deposition of organic films equipped with optical spectrometer for measurements <i>in situ</i>. We are developing new dyes aimed for application in waveguide sensor, nonlinear optics and studying film organisation during deposition. Fluorinated azo-dyes and azomethine dyes were synthesized at University of Applied Sciences Wildau and at the Institute of Organic Chemistry, Kyiv. Compounds were evaporated at a pressure of 10-<sup>3</sup> Pa using resistive heated crucible. Glass and glass covered with polytetrafluoroethylene (PTFE) film are used as substrates. The films were studied with Polytec and StellarNet spectrometers and an atomic force microscope. Optical spectra of the dye films revealed, that some compounds were decomposed during evaporation. Several kinds of dyes were evaporated and deposited without decomposition. Some deposited films formed H-aggregates and other types of aggregates. AFM images of dye films showed that their morphology depends on the chemical structure of the compounds and on the nature of the substrate on which the film was grown.
EFFECT OF DUAL INOCULATION WITH ARBUSCULAR MYCORRHIZAL FUNGI AND BACTERIA ON GROWTH AND MINERAL NUTRITION OF STRAWBERRY (2002)

ABSTRACT Micropropagated plants of Fragaria x ananassa (cv. Senga sengana) were post-vitro inoculated in two experiments with the arbuscular mycorrhizal fungi Glomus fasciculatum, Glomus etunicatum and or Glomus claroideum and with bacterial isolates obtained from plant rhizosphere, from mycorrhizal mycelium and from root-free substrate. In the first experiment, the inoculation with the bacterial isolate M30 (from mycorrhizal mycelium) and with arbuscular mycorrhizal fungi G. fasciculatum and G. etunicatum significantly increased the plant growth. Bacteria frequently stimulated development of mycorrhiza, particularly the growth and dehydrogenase activity of extraradical mycorrhizal mycelium. In the second experiment, the isolate-specific effects of bacteria and mycorrhizal fungi were found at different doses of phosphorus (P) and nitrogen (N). The interaction between nutritional regime, bacteria and the fungi may be a determining factor of mycorrhizal symbiosis efficiency as regards possible benefits in stimulation of plant growth.

Intact Learning of New Relations in Amnesia as Achieved through Unitization (2013)

Hippocampal amnesia is defined by deficits in the binding of relations among items--a deficit captured by the transverse patterning (TP) task. Unitization is a processing mechanism that may allow amnesic patients to compensate for relational memory deficits. Amnesic patient D.A. demonstrated intact TP, and performance was maintained 1 month following training. Successful acquisition of relations occurred only when D.A. fused or integrated objects into a unified representation. D.A. did not acquire relations when he did not generate such integrated scenarios, and acquisition of relations was slowed when integration had to occur for novel stimuli. Amnesic patients K.C. and R.F.R. were tested to provide comparative data; K.C. and R.F.R. did not benefit from unitization, perhaps due to additional cortical damage. We propose that unitization requires visual imagery of multiple items that are fused/integrated; through the benefit of extended on-line maintenance, this fused representation is anchored to existing representations in semantic memory.
Effect of Dislocations on Breakdown in Silicon p-n Junctions (1958)

The light emission patterns of silicon diffused p-n junctions at breakdown have been compared with the etch-pit patterns that reveal dislocations. It is concluded that avalanche breakdown microplasmas occur preferentially where dislocations pass through the junction. In narrow p-n junctions, large numbers of dislocations result in enhanced internal field emission and, consequently, a soft reverse characteristic. A qualitative correlation is found between the nature of the light emission pattern (spots for avalanche breakdown, glow for field emission) and the quality of the reverse characteristic. Possible reasons why breakdown should occur preferentially at dislocations are discussed though no precise conclusion is reached. Peculiar singularities observed in the light emission patterns of some junctions were found to coincide with crystal abnormalities revealed in the etch patterns.
3D-nanostructured boron-doped diamond for microelectrode array neural interfacing (2015)

The electrode material is a key element in the design of long-term neural implants and neuroprostheses. To date, the ideal electrode material offering high longevity, biocompatibility, low-noise recording and high stimulation capabilities remains to be found. We show that 3D-nanostructured boron doped diamond (BDD), an innovative material consisting in a chemically stable material with a high aspect ratio structure obtained by encapsulation of a carbon nanotube template within two BDD nanolayers, allows neural cell attachment, survival and neurite extension. Further, we developed arrays of 20-μm-diameter 3D-nanostructured BDD microelectrodes for neural interfacing. These microelectrodes exhibited low impedances and low intrinsic recording noise levels. In particular, they allowed the detection of low amplitude (10-20 μV) local-field potentials, single units and multiunit bursts neural activity in both acute whole embryonic hindbrain-spinal cord preparations and long-term hippocampal cell cultures. Also, cyclic voltammetry measurements showed a wide potential window of about 3 V and a charge storage capacity of 10 mC.cm(-2), showing high potentiality of this material for neural stimulation. These results demonstrate the attractiveness of 3D-nanostructured BDD as a novel material for neural interfacing, with potential applications for the design of biocompatible neural implants for the exploration and rehabilitation of the nervous system.
Imaging extended objects with a Fresnel-zone-plate aperture (1974)

A theoretical investigation of the imaging of extended objects is presented using a Fresnel zone plate as a coded aperture with coherent-optical image reconstruction. Faithful images are obtained only for small objects; artifacts are introduced in the images of large objects. Attempts to increase image fidelity are shown to be only moderately successful.
Influence of Polymerization Conditions on Melting Kinetics of Low Entangled UHMWPE and Its Implications on Mechanical Properties (2014)

The synthesis of linear ultra high molecular weight polyethylene, with a “pseudoliving” catalyst in various conditions results in samples of different molecular weights (Mw ranging between 2 to 35 million g/mol), all having a reduced number of entanglements to an extent that allows the solid-state uniaxial deformation of such high molar masses without melting. The solid-state processing of these materials shows a clear relationship between mechanical properties and molecular weight. For the adopted polymerization conditions, stretching forces required for the uniaxial deformation increase with the increasing molar mass, ultimately limiting the achievable maximum draw ratio in the polymers having Mw > 10 million g/mol. The increase in the stretching force is attributed to the increasing number of entanglements between the crystals with the molar mass. The estimation of entanglements is established with the help of melting kinetics involved in the “disentangled” crystals, and rheological response of the polymer melt obtained just after melting of the crystals. In spite of the increase in the stretching forces with the increasing molar mass, tensile modulus increases with the increasing draw ratio and the molecular weight. However, above the molar mass of 10 million g/mol, the stretching force required increases to the level that the uniaxial deformation becomes difficult–thus limiting the tensile strength.
Seismosaurus halli, gen. et sp. nov., a new sauropod dinosaur from the Morrison Formation (Upper Jurassic/Lower Cretaceous) of New Mexico, USA (1991)

ABSTRACT Seismosaurus halli, gen. et sp. nov. (Sauropoda, Diplodocidae) is a new large sauropod from the Brushy Basin Member of the Morrison Formation (Upper Jurassic/Lower Cretaceous) of central New Mexico. The holotype is a partially articulated skeleton consisting to date of approximately 20 caudal vertebrae, five sacral vertebrae, eight dorsal vertebrae, partial pelvis, five chevrons, and ribs. Distinguishing features include the structure of the caudal vertebrae, pelvis, and chevrons. The extraordinary dimensions of these bones indicate an axial length of 39–52 meters.

Simplified BNWF model for nonlinear seismic response analysis of offshore piles with nonlinear input ground motion analysis (2005)

The seismic response of pile-supported offshore structures is strongly affected by the nonlinear behavior of the supporting piles. Nonlinear response of the pile foundation is the most important source of potential nonlinearity in the dynamic response of offshore platforms to earthquake excitations. It is often necessary to perform a dynamic analysis of offshore platforms that accounts for soil nonlinearity, discontinuity conditions at pilesoil interfaces, energy dissipation through soil radiation damping, and structural nonlinear behaviors of piles. In this paper, an attempt is made to develop an inexpensive and practical procedure, compatible with readily available structural analysis software, for estimating the lateral response of flexible piles embedded in layered soil deposits subjected to seismic loading. In the proposed model a beam on nonlinear Winkler foundation (BNWF) approach, consisting of simple nonlinear springs, dashpots, and contact elements, is used. This model was incorporated into a finite element program, ANSYS, which was used to compute the response of laterally excited piles. A nonlinear approach was used for seismic free-field ground motion analysis. The computed responses compared well with the centrifuge test results. This paper deals with the effects of free-field ground motion analysis on nonlinear seismic behavior of embedded piles. Different parts of a BNWF model, together with quantitative and qualitative findings and conclusions for dynamic nonlinear response of offshore piles, are discussed and addressed in detail.Key words: nonlinear, seismic response, offshore piles, seismic pilesoil interaction, BNWF models.
Transmission-Efficient Clustering Method for Wireless Sensor Networks Using Compressive Sensing (2013)

Compressive sensing (CS) can reduce the number of data transmissions and balance the traffic load throughout networks. However, the total number of transmissions for data collection by using pure CS is still large. The hybrid method of using CS was proposed to reduce the number of transmissions in sensor networks. However, the previous works use the CS method on routing trees. In this paper, we propose a clustering method that uses hybrid CS for sensor networks. The sensor nodes are organized into clusters. Within a cluster, nodes transmit data to cluster head (CH) without using CS. CHs use CS to transmit data to sink. We first propose an analytical model that studies the relationship between the size of clusters and number of transmissions in the hybrid CS method, aiming at finding the optimal size of clusters that can lead to minimum number of transmissions. Then, we propose a centralized clustering algorithm based on the results obtained from the analytical model. Finally, we present a distributed implementation of the clustering method. Extensive simulations confirm that our method can reduce the number of transmissions significantly.

Low Vitamin D level at admission did not affect 30-day mortality of critically ill patients on mechanical ventilation.
CheckFence (2007)

Concurrency libraries can facilitate the development of multi-threaded programs by providing concurrent implementations of familiar data types such as queues or sets. There exist many optimized algorithms that can achieve superior performance on multiprocessors by allowing concurrent data accesses without using locks. Unfortunately, such algorithms can harbor subtle concurrency bugs. Moreover, they requirememory ordering fences to function correctly on relaxed memory models. To address these difficulties, we propose a verification approach that can exhaustively check all concurrent executions of a given test program on a relaxed memory model and can verify that they are observationally equivalent to a sequential execution. Our CheckFence prototype automatically translates the C implementation code and the test program into a SAT formula, hands the latter to a standard SAT solver, and constructs counter example traces if there exist incorrect executions. Applying CheckFence to five previously published algorithms, we were able to (1) find several bugs (some not previously known), and (2) determine how to place memory ordering fences for relaxed memory models.
Multiple Object Tracking with Kernelized Correlation Filters in Urban Mixed Traffic (2016)

Recently, the Kernelized Correlation Filters tracker (KCF) achieved competitive performance and robustness in visual object tracking. On the other hand, visual trackers are not typically used in multiple object tracking. In this paper, we investigate how a robust visual tracker like KCF can improve multiple object tracking. Since KCF is a fast tracker, many can be used in parallel and still result in fast tracking. We build a multiple object tracking system based on KCF and background subtraction. Background subtraction is applied to extract moving objects and get their scale and size in combination with KCF outputs, while KCF is used for data association and to handle fragmentation and occlusion problems. As a result, KCF and background subtraction help each other to take tracking decision at every frame. Sometimes KCF outputs are the most trustworthy (e.g. during occlusion), while in some other case, it is the background subtraction outputs. To validate the effectiveness of our system, the algorithm is demonstrated on four urban video recordings from a standard dataset. Results show that our method is competitive with state-of-the-art trackers even if we use a much simpler data association step.
On assessing the robustness of pen coordinates, pen pressure and pen inclination to time variability with personal entropy (2009)

In this work, we study different combinations of the five time functions captured by a digitizer in presence or not of time variability. To this end, we propose two criteria independent of the classification step: personal entropy, introduced in our previous works and an intra-class variability measure based on dynamic time warping. We confront both criteria to system performance using a hidden Markov model (HMM) and dynamic time warping (DTW). Moreover, we introduce the concept of short-term time variability, proposed on MCYT-100, and long-term time variability studied with BIOMET database. Our experiments clarify conflicting results in the literature and confirm some other: pen inclination angles are very unstable in presence or not of time variability; the only combination which is robust to time variability is that containing only coordinates; finally, pen pressure is not recommended in the long-term context, although it may give better results in terms of performance (according to the classifier used) in the short-term context.
