Probabilistic detection and tracking of motion discontinuities (1999)

We propose a Bayesian framework for representing and recognizing local image motion in terms of two primitive models: translation and motion discontinuity. Motion discontinuities are represented using a nonlinear generative model that explicitly encodes the orientation of the boundary, the velocities on either side, the motion of the occluding edge over time, and the appearance/disappearance of pixels at the boundary. We represent the posterior distribution over the model parameters given the image data using discrete samples. This distribution is propagated over time using the Condensation algorithm. To efficiently represent such a high-dimensional space we initialize samples using the responses of a low-level motion discontinuity detector.
Complete Genome Sequence and Methylome Analysis of Bacillus globigii ATCC 49760 (2016)

Bacillus subtilis (Ehrenburg) Cohn ATCC 49760, deposited as Bacillus globigii, is the source strain for the restriction enzymes BglI and BglII. Its complete sequence and full methylome were determined using single-molecule real-time (SMRT) sequencing.
Holography in museums – why not go 3‐D? (1992)

Holography is a new way of recording and reproducing three‐dimensional graphic information. In recent years, it has acquired wide recognition as a scientific tool for research and other purposes. It can, for example, assist in non‐destructive testing of different objects, in optical information processing and also in medical and biological work. In this article, the Director of the Laboratory of Applied Holography of the Ukrainian Academy of Science's Institute of Physics offers a typology of museum‐related uses of holography, and suggests avenues for further development.
Antenna Selection for Upper Millimeter Wave and THz Bands (2020)

The evolution of Fifth Generation (5G) systems into the upper millimeter wave and Terahertz (THz) bands is expected to enable the sustained growth of peak data rates in a cellular setting. While propagation and blockage challenges would limit the coverage to a small cell setting, array gain increases due to the packing of a large number of antenna elements in a given physical aperture could sustain continued spectral efficiency increases in these bands. In contrast to lower millimeter wave bands, increases in power consumption, thermal challenges and beam learning latencies limit the number of antenna elements that can be gainfully employed at any point in time. With this background, the focus of this work is on understanding antenna selection challenges (at an implementation level from a standardization perspective) in the upper millimeter wave and THz bands. We provide insights into the use of appropriate antenna dimensions and scalable beam learning algorithms for antenna selection at these bands.

Downlink Beamforming for SWIPT Multi-User MISO Underlay Cognitive Radio Networks (2016)

This letter investigates downlink beamforming for simultaneous wireless information and power transfer in multi-user multi-input single-output underlay cognitive radio networks. Under the assumption of the integrated power splitting (PS) receiver architecture at the secondary receivers, we aim to minimize the total transmission power from the secondary base station by jointly optimizing the beamforming vectors and the PS ratios. We first exploit the structure of the relaxed problem to provide a closed form expression for the optimal solution. Since the underlying optimization problem is non-convex, we resort to semidefinite programming relaxation and we analytically prove that the relaxation is in fact tight and yields optimal beamforming solution.
Study Of Indium Tin Oxide Films Exposed To Atomic Oxygen (1989)

Indium tin oxide thin films (650 &Aring;) were prepared by dc sputtering onto room temperature substrates. The films were exposed to an rf excited oxygen plasma, to qualitatively simulate the effects of atomic oxygen. Changes in optical, electrical, and structural properties were characterized as a function of exposure time.

WDM polymer substrate mode photonic interconnects for satellite communications (2004)

WDM is an enabling technology for future satellite communications to increase capacity of bandwidth and network efficiency. Polymer based substrate mode optical interconnects is advantageous over its competing technologies, such as waveguide and free space approaches, in terms of insertion loss, robustness, and packaging. In this paper, we will describe polymer substrate mode photonic interconnects and their reconfiguration functions for separation of coarse and dense wavelength channels.
Anti-DNA antibodies are a major component of the intrathecal B cell response in multiple sclerosis (2001)

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of unknown cause that afflicts the central nervous system. MS is typified by a highly clonally restricted antigen-driven antibody response that is confined largely to the central nervous system. The major antigenic targets of this response and the role of antibody in disease pathogenesis remain unclear. To help resolve these issues, we cloned the IgG repertoire directly from active plaque and periplaque regions in MS brain and from B cells recovered from the cerebrospinal fluid of a patient with MS with subacute disease. We found that high-affinity anti-DNA antibodies are a major component of the intrathecal IgG response in the patients with MS that we studied. Furthermore, we show DNA-specific monoclonal antibodies rescued from two subjects with MS as well as a DNA-specific antibody rescued from an individual suffering from systemic lupus erythematosus bound efficiently to the surface of neuronal cells and oligodendrocytes. For two of these antibodies, cell-surface recognition was DNA dependent. Our findings indicate that anti-DNA antibodies may promote important neuropathologic mechanisms in chronic inflammatory disorders, such as MS and systemic lupus erythematosus.
Physical-Layer Cell ID Detection Probability Using NR Synchronization Signals for 3GPP TDL Channel Models (2021)

This paper presents physical-layer cell identity (PCID) detection probability using synchronization signals for the 5G New Radio (NR) initial access in 3rd generation partnership project (3GPP) tapped delay line (TDL) channel models. Computer simulation results validate the PCID detection probability based on the cumulative distribution of the instantaneous received power level of the synchronization signal for the respective channel models. We also show that the high PCID detection probability is achieved by using the NR synchronization signals in the 3GPP TDL channel models.

Magnetic Nanoparticles: Unravelling Magnetic Nanochain Formation in Dispersion for In Vivo Applications (Adv. Mater. 24/2021) (2021)

Spherical iron oxide nanoparticles in dispersion are controlled by external magnetic fields to form flexible and reversible chains for biomedical applications. In article number 2008683, Mikhail Feygenson and co-workers combine the advanced scattering methods and reverse Monte Carlo simulations to directly visualize the chain formation in real space. This methodology paves the way for exploring novel assemblies of particles with a complex morphology in various liquid carriers.
Susceptibility to 3BNC117 and 10-1074 in ART suppressed chronically infected persons (2023)

The reduced combined susceptibility of 3BNC117 and 10-1074 highlights a potential limitation of using only two bnAbs for pre-exposure prophylaxis or treatment. Further studies are needed to define and validate the clinical correlates of bnAb susceptibility.
The stable equivalence and cancellation problems (2004)

Let K be an arbitrary field of characteristic 0, and \mathbf{A}^n the n-dimensional affine space over K. A well-known cancellation problem asks, given two algebraic varieties V_1, V_2 \subseteq \mathbf{A}^n with isomorphic cylinders V_1 \times \mathbf{A}^1 and V_2 \times \mathbf{A}^1 , whether V_1 and V_2 themselves are isomorphic. In this paper, we focus on a related problem: given two varieties with equivalent (under an automorphism of \mathbf{A}^{n+1} ) cylinders V_1 \times \mathbf{A}^1 and V_2 \times \mathbf{A}^1 , are V_1 and V_2 equivalent under an automorphism of \mathbf{A}^n ? We call this stable equivalence problem. We show that the answer is positive for any two curves V_1, V_2 \subseteq \mathbf{A}^2 . For an arbitrary n \ge 2 , we consider a special, arguably the most important, case of both problems, where one of the varieties is a hyperplane. We show that a positive solution of the stable equivalence problem in this case implies a positive solution of the cancellation problem.
Information assurance in manets and wireless sensor networks (2005)

Manets and sensor networks are two classes of the wireless ad hoc networks with resource constraints. Manets typically consist of devices that have high capabilities, mobile and operate in coalitions. Sensor networks are typically deployed in specific geographical regions for monitoring and sensing. Both these wireless networks are characterized by their ad hoc nature that lack pre deployed infrastructure for computing and communication. Resource constraints, medium pathloss, and signal interference limit the communication range between any tow nodes, leading to the need for a multihop communication network. Such a network must be collaboratively formed and supported by the resource constraint nodes. For meaningful service provision, such a network must be able to provide confidentiality, integrity, and entity verification among participating nodes. In this talk, we will focus on such networks and discuss the challenges ahead that require fresh approaches in trust establishment and secure network service operations. We will take secure location services, probabilistic pre key deployment strategies, and group mobility scenarios of VANETs as examples to demonstrate the challenges in trust establishment and providing privacy.

Revision der Struktur von Tolyporphin A (1999)

Aus vier monocyclischen Vorstufen gelang die Totalsynthese der für (+)-Tolyporphin-A-O,O-diacetat vorgeschlagenen Struktur 1-A (X = Ac). Ein Vergleich der spektroskopischen Daten ergab, daß das synthetische Tolyporphin-O,O-diacetat nicht mit dem aus natürlichem (+)-Tolyporphin A (X = H) hergestellten O,O-Diacetat übereinstimmte – eine Korrektur der Struktur dieser Naturstoffklasse war gefordert. Aus einer Reihe von NMR-Experimenten, unter anderem an synthetischen Zwischenprodukten, ließ sich als wahrscheinliche Struktur für den Naturstoff die Struktur 1-B folgern, in der die Konfigurationen der quartären Kohlenstoffzentren C7 und C17 umgekehrt wie ursprünglich angenommen sind.
Run-time adaptive on-chip communication scheme (2007)

During run-time varying workloads and/or constraints in embedded systems require run-time adaptivity to provide a high degree of efficiency during any operation mode/scenario. Design time decisions can often only cover certain scenarios and fail in efficiency when hard-to-predict system scenarios occur. We are presenting the first approach of an adaptive on-chip communication scheme. It provides an adaptive routing/path allocation algorithm to meet a required level of QoS (guaranteed bandwidth). In our architecture adaptive runtime links are established by re-assigning buffer blocks ondemand. This adaptive buffer allocation scheme increases the buffer utilization and decreases the overall buffer use on an average of 42% in our case study analysis compared to a fixed buffer assignment strategy. The area overhead introduced by the adaptive scheme can be traded-off against the flexibility in order to select an available path and on-demand buffer allocation. We demonstrate the advantage by using various real world digital media applications and compare our approach to the state-ofthe- art static on-chip communication schemes.
An additional 5'-upstream exon exists in the human pleiotrophin-encoding gene (1995)

A 2-kb 5' fragment of hPTN (human pleiotrophin-encoding) genomic DNA was sequenced. Within this region we identified a new, upstream exon (U2). Cloning and sequencing of the PCR products of cDNAs from a human melanoma cell line revealed that a 401-bp intron was spliced out between exon U2 and a previously described untranslated exon U1. Our analysis also revealed that previously reported transcription start points (tsp) of PTN are located within exon U1.
Beta-chain broadens range of CD8 recognition for MHC class I molecule (1992)

It is known that the alpha-chain of CD8 binds to a negatively charged loop composed of residues 223 to 229 on MHC class I Ag and that binding of CD8 alpha enhances Ag recognition of T cells. We have recently shown that the mouse CD8 alpha homodimer does not bind to either the HLA class I alpha 3 domain or a mutant of H-2Kb Ag containing a substitution of glutamine for methionine at residue 224, which brings this residue toward the human consensus. Here we report a complementary study of the CD8 beta-chain. The functional role of the CD8 beta-chain was analyzed by using four T cell hybridoma lines expressing mouse CD8 alpha and transfected with the mouse CD8 beta gene. As compared with the lines expressing only CD8 alpha, allorecognition of the chimeric H-2Kb Ag that contains the HLA class I alpha 3 domain was enhanced in lines expressing both CD8 alpha and -beta. This enhancement was blocked by either anti-CD8 mAb or anti-HLA class I alpha 3 domain mAb. In addition, we show that CD8 alpha beta binds the H-2Kb mutant Ag at residue 224. These results suggest that the beta-chain allows the CD8 alpha beta heterodimer to recognize the chimeric H-2Kb Ag. A model for the role of the beta-chain is presented.
A new application level link aggregation and its implementation on Android terminals (2012)

Link aggregation bundles multiple physical links on a single virtual link, enabling very high-speed and large-capacity data communications. It also enables redundant communications. Several link aggregation methods have been proposed. These methods utilize transport layer link aggregation. In this paper, a new application level link aggregation is proposed and implemented on Android OS, which is one of the popular OSs for mobile devices such as smartphones and tablet PCs. The proposed application level link aggregation method is verified with use of an implemented terminal.
Highly-parallelized simulation of a pixelated LArTPC on a GPU (2023)

The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation of highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique is particularly suitable for the simulation of a pixelated charge readout for time projection chambers, given the large number of channels that this technology employs. Here we present the first implementation of a full microphysical simulator of a liquid argon time projection chamber (LArTPC) equipped with light readout and pixelated charge readout, developed for the DUNE Near Detector. The software is implemented with an end-to-end set of GPU-optimized algorithms. The algorithms have been written in Python and translated into CUDA kernels using Numba, a just-in-time compiler for a subset of Python and NumPy instructions. The GPU implementation achieves a speed up of four orders of magnitude compared with the equivalent CPU version. The simulation of the current induced on 10^3 pixels takes around 1 ms on the GPU, compared with approximately 10 s on the CPU. The results of the simulation are compared against data from a pixel-readout LArTPC prototype.
Novel PIGT Variant in Two Brothers: Expansion of the Multiple Congenital Anomalies-Hypotonia Seizures Syndrome 3 Phenotype (2016)

Biallelic <i>PIGT</i> variants were previously reported in seven patients from three families with Multiple Congenital Anomalies-Hypotonia Seizures Syndrome 3 (MCAHS3), characterized by epileptic encephalopathy, hypotonia, global developmental delay/intellectual disability, cerebral and cerebellar atrophy, craniofacial dysmorphisms, and skeletal, ophthalmological, cardiac, and genitourinary abnormalities. We report a novel homozygous <i>PIGT</i> missense variant c.1079G>T (p.Gly360Val) in two brothers with several of the typical features of MCAHS3, but in addition, pyramidal tract neurological signs. Notably, they are the first patients with MCAHS3 without skeletal, cardiac, or genitourinary anomalies. <i>PIGT</i> encodes a crucial subunit of the glycosylphosphatidylinositol (GPI) transamidase complex, which catalyzes the attachment of proteins to GPI-anchors, attaching the proteins to the cell membrane. In vitro studies in cells from the two brothers showed reduced levels of GPI-anchors and GPI-anchored proteins on the cell surface, supporting the pathogenicity of the novel <i>PIGT</i> variant.
Multi-code multicarrier CDMA: performance analysis (2004)

A novel multi-code multicarrier code division multiple access (MC-MC-CDMA) system is proposed and analyzed in a frequency selective fading channel. By allowing each user to transmit multiple orthogonal codes, the proposed MC-MC-CDMA system can support various data rates, as required by next generation standards, and achieve spreading gain in the time domain. Multicarrier CDMA provides robustness to multipath and spreading in the frequency domain. The bit error rate of the system is analytically derived in frequency selective fading, with Gaussian noise and multiple access interference. The results show that the proposed MC-MC-CDMA system clearly outperforms both single-code multicarrier CDMA (MC-CDMA) and single-carrier multi-code CDMA in a fixed bandwidth allocation. This indicates that MC-MC-CDMA should be seriously considered for next generation cellular systems.
Development of siRNA-probes for studying intracellular trafficking of siRNA nanoparticles (2012)

One important barrier facing the delivery of short interfering RNAs (siRNAs) via synthetic nanoparticles is the rate of nanoparticle disassembly. However, our ability to optimize the release kinetics of siRNAs from nanoparticles for maximum efficacy is limited by the lack of methods to track their intracellular disassembly. Towards this end, we describe the design of two different siRNA-based fluorescent probes whose fluorescence emission changes in response to the assembly state of the nanoparticle. The first probe design involves a redox-sensitive fluorescence-quenched probe that fluoresces only when the nanoparticle is disassembled in a reductive environment. The second probe design is based on a FRET-labeled siRNA pair that fluoresces due to the proximity of the siRNA pair when the nanoparticle is intact. In both approaches, the delivery vehicle need not be labeled. The utility of these probes was investigated with a lipidoid nanoparticle (LNP) as proof-of-concept in both extracellular and intracellular environments. Fluorescence kinetic data from both probes were fit to a two-phase release and decay curve and subsequently quantified to give intracellular disassembly rate constants. Quantitative analysis revealed that the rate constant of siRNA release measured via the fluorescence-quenched probe was almost identical to the rate constant for nanoparticle disassembly measured via the FRET-labeled probes. Furthermore, these probes were utilized to determine subcellular localization of LNPs with the use of automated high-resolution microscopy as they undergo dissociation. Interestingly, this work shows that large amounts of siRNA remain inside vesicular compartments. Altogether, we have developed new siRNA probes that can be utilized with multiple nanocarriers for quantitative and qualitative analysis of nanoparticle dissociation that may serve as a design tool for future delivery systems.
Ciliary Body Adenoma in a 10-Year-Old Girl Who Had a Rhabdomyosarcoma (1992)

A retrolenticular fibrovascular membrane occurred in the setting of a ciliary body mass in a 10-year-old black girl who had been successfully treated for a rhabdomyosarcoma of the lung. The results of a transscleral biopsy of the mass demonstrated it to be a pigmented adenoma of the ciliary body. A lensectomy and membranectomy were performed to aid in the follow-up and rehabilitation of the eye. At 9 months after surgery, the patient had 20/25 vision with no evidence of tumor growth. This case demonstrates an unusual cause of cyclitic membrane formation and suggests that transscleral biopsy may be a useful adjunct in the management of selected ciliary body masses.
