Multilinear Dynamical Systems for Tensor Time Series (2013)

Data in the sciences frequently occur as sequences of multidimensional arrays called tensors. How can hidden, evolving trends in such data be extracted while preserving the tensor structure? The model that is traditionally used is the lin-ear dynamical system (LDS), which treats the latent state and observation at each time slice as vectors. We present the multilinear dynamical system (MLDS) for modeling tensor time series and an expectation–maximization (EM) algorithm to estimate the parameters. The MLDS models each tensor observation in a series as the multilinear projection of a corresponding member of a sequence of latent tensors. The latent tensors are again evolving with respect to a multilinear pro-jection. Compared to the LDS with an equal number of parameters, the MLDS achieves higher prediction accuracy and marginal likelihood for both artificial and real datasets. 1
The syndrome of IgA nephropathy. (1984)

A review is presented of the current knowledge concerning the syndrome of IgA nephropathy. Primary and secondary forms can now be delineated and this division has improved understanding of immunopathogenetic mechanisms giving rise to glomerular mesangial IgA deposits. Attention is paid to disorders of antigen exclusion at mucosal surfaces, defective reticulo-endothelial sequestration, and altered immunoglobulin A production and regulation. Particular reference is made to these mechanisms with respect to primary IgA nephropathy, Henoch-Schoenlein purpura and mesangial IgA nephritis associated with alcoholic cirrhosis.
Spatial correlation in real-time video conference traffic (2002)

Multimedia traffic measurements for determining spatial correlation in videoteleconference sessions over a CSMA/CD LAN are performed and the results are presented in this paper. Since packet arrival streams are both correlated and bursty, we present the analysis of the cross-correlation characteristics between the number of arriving audio and video packet batches in discrete-time slots. The results of this experimental study can be extended to WAN environments such as ATM. If cross-correlation among monomedia streams is not properly taken into account, it can severely impact network performance.

Paclitaxel promotes differentiation of myeloid-derived suppressor cells into dendritic cells<i>in vitro</i>in a TLR4-independent manner (2012)

Myeloid cells play a key role in the outcome of anti-tumor immunity and response to anti-cancer therapy, since in the tumor microenvironment they may exert both stimulatory and inhibitory pressures on the proliferative, angiogenic, metastatic, and immunomodulating potential of tumor cells. Therefore, understanding the mechanisms of myeloid regulatory cell differentiation is critical for developing strategies for the therapeutic reversal of myeloid derived suppressor cell (MDSC) accumulation in the tumor-bearing hosts. Here, using an in vitro model system, several potential mechanisms of the direct effect of paclitaxel on MDSC were tested, which might be responsible for the anti-tumor potential of low-dose paclitaxel therapy in mice. It was hypothesized that a decreased level of MDSC in vivo after paclitaxel administration might be due to (i) the blockage of MDSC generation, (ii) an induction of MDSC apoptosis, or (iii) the stimulation of MDSC differentiation. The results revealed that paclitaxel in ultra-low concentrations neither increased MDSC apoptosis nor blocked MDSC generation, but stimulated MDSC differentiation towards dendritic cells. This effect of paclitaxel was TLR4-independent since it was not diminished in cell cultures originated from TLR4-/- mice. These results support a new concept that certain chemotherapeutic agents in ultra-low non-cytotoxic doses may suppress tumor progression by targeting several cell populations in the tumor microenvironment, including MDSC.
Phosphorus Rich d<sup>10</sup> Ion Polyphosphides and Selected Materials (2015)

Abstract Polyphosphides composed by late transition metal ions with closed d 10 shells are subject of this review. Recent progress has been made during the past years in this field and many new compounds have been discovered. The spectrum of compounds extends from classical binary and ternary compounds, adduct phases of metal halides and molecular species to composites of intermetalloid clusters and molecular anion substructures. Phosphorus is highly reactive to late transition metals forming d 10 ions and they entirely react to a plenthora of materials. Only a handful of elements do not form binary compounds with phosphorus and the number is decreasing. This review is focussed on synthetic procedures and the structure property relations of d 10 ion polyphosphides. A brief overview is also given to the progress in phosphorus allotrope chemistry and their perspectives and applications. Especially black phosphorus as active material for batteries and its de‐laminated form “phosphorene” is added.
From ethnographic study to mixed reality (2011)

In this paper we describe how we moved from ethnographic study to design and testing of a Mixed Reality (MR) system, supporting collaborative troubleshooting of office copiers and printers. A key CSCW topic is how remotely situated people can collaborate around physical objects which are not mutually shared, without introducing new interactional problems. Our approach, grounded in an ethnographic study of a troubleshooting call centre, was to create a MR system centred on a shared 3D problem representation, rather than to use video or Augmented Reality (AR)-based systems. The key drivers for this choice were that given the devices are sensor equipped and networked, such a representation can create reciprocal viewpoints onto the current state of this particular machine without requiring additional hardware. Testing showed that troubleshooters and customers could mutually orient around the problem representation and found it a useful troubleshooting resource.
An Architecture for UMTS-WIMAX Interworking (2006)

One motivation of Next Generation Networks is the ubiquitous wireless access abilities which provide the automatic handovers for any moving devices in the heterogeneous networks combining different access technologies. In this paper, we present a possible UMTS-WIMAX interworking architecture based on the 3GPP standards and propose the seamless inter-system handover scheme which enables the service continuity with low handover latency and packet loss.
Livescan3D: A Fast and Inexpensive 3D Data Acquisition System for Multiple Kinect v2 Sensors (2015)

LiveScan3D is a free, open source system for live, 3D data acquisition using multiple Kinect v2 sensors. It allows the user to place any number of sensors in any physical configuration and start gathering data at real time speed. The freedom of placing the sensors in any configuration allows for many possible acquisition scenarios such as: capturing a single object from many viewpoints or creating 3D panoramas with multiple devices located close to each other. Thanks to the off-the-shelf Kinect v2 sensor the system is both accurate and inexpensive, opening 3D acquisition up to more recipients. In the paper we describe our system with the algorithms it is using and show its effectiveness in multiple scenarios including head shape reconstruction and 3D reconstruction of dynamic scenes.

<title>The other fiber, the other fabric, the other way</title> (1993)

Coaxial cable and distributed switches provide a way to configure high-speed Fiber Channel fabrics. This type of fabric provides a cost-effective alternative to a fabric of optical fibers and centralized cross-point switches. The fabric topology is a simple tree. Products using parallel busses require a significant change to migrate to a serial bus. Coaxial cables and distributed switches require a smaller technology shift for these device manufacturers. Each distributed switch permits both medium type and speed changes. The fabric can grow and bridge to optical fibers as the needs expand. A distributed fabric permits earlier entry into high-speed serial operations. For very low-cost fabrics, a distributed switch may permit a link configured as a loop. The loop eliminates half of the ports when compared to a switched point-to-point fabric. A fabric of distributed switches can interface to a cross-point switch fabric. The expected sequence of migration is: closed loops, small closed fabrics, and, finally, bridges, to connect optical cross-point switch fabrics. This paper presents the concept of distributed fabrics, including address assignment, frame routing, and general operation.
Colloidal Hydrogel Microlenses (2003)

The creation of microlenses from hydrogel microparticles is demonstrated. The fabrication of substrate‐supported microgels is performed using electrostatic interactions between aminopropyltrimethoxysilane‐functionalized glass substrates and acrylic acid groups present on the microgel surface. The lensing ability is illustrated by imaging a photomask through each of the microgels present on the surface (see Figure).
A Heterologous, High-Affinity RNA Ligand for Human Immunodeficiency Virus Gag Protein Has RNA Packaging Activity (2000)

Retroviral RNA encapsidation depends on the specific binding of Gag proteins to packaging (psi) signals in genomic RNA. We investigated whether an in vitro-selected, high-affinity RNA ligand for the nucleocapsid (NC) portion of the Gag protein from human immunodeficiency virus type 1 (HIV-1) could mediate packaging into HIV-1 virions. We find that this ligand can functionally substitute for one of the Gag-binding elements (termed SL3) in the HIV-1 psi locus to support packaging and viral infectivity in cis. By contrast, this ligand, which fails to dimerize spontaneously in vitro, is unable to replace a different psi element (termed SL1) which is required for both Gag binding and dimerization of the HIV-1 genome. A single point mutation within the ligand that eliminates high-affinity in vitro Gag binding also abolishes its packaging activity at the SL3 position. These results demonstrate that specific binding of Gag or NC protein is a critical determinant of genomic RNA packaging.
Design of multi-invariant data structures for robust shared accesses in multiprocessor systems (2001)

Multiprocessor systems are widely used in many application programs to enhance system reliability and performance. However, reliability does not come naturally with multiple processors. We develop a multi-invariant data structure approach to ensure efficient and robust access to shared data structures in multiprocessor systems. Essentially, the data structure is designed to satisfy two invariants, a strong invariant, and a weak invariant. The system operates at its peak performance when the strong invariant is true. The system will operate correctly even when only the weak invariant is true, though perhaps at a lower performance level. The design ensures that the weak invariant will always be true in spite of fail-stop processor failures during the execution. By allowing the system to converge to a state satisfying only the weak invariant, the overhead for incorporating fault tolerance can be reduced. We present the basic idea of multi-invariant data structures. We also develop design rules that systematically convert fault-intolerant data abstractions into corresponding fault-tolerant versions. In this transformation, we augment the data structure and access algorithms to ensure that the system always converges to the weak invariant, even in the presence of fail-stop processor failures. We also design methods for the detection of integrity violations and for restoring the strong invariant. Two data structures, namely binary search tree and double-linked list, are used to illustrate the concept of multi-invariant data structures.
Selective growth of carbon nanotubes for nano electro mechanical device (2002)

In this paper, we present the growth techniques of carbon nanotubes and its application for nano-electromechanical devices. Several methods were attempted for the selective growth of the carbon nanotubes. Catalyzed metal (Ni) patterning and the following hot-filament chemical vapor deposition enable to grow carbon nanotubes on the metal pattern formed on quartz glass. However, no carbon nanotubes are grown on a flat silicon substrate using this method. It is found that the high electrostatic field with a negative substrate bias enhances the growth of the carbon nanotubes. This growth enhancement effect is applied to fabricate single carbon nanotube tip on silicon for scanning probe microscopy.
Mechanism of stress aging in Al-Cu(-Mg-Ag) alloys (2004)

The effect of stress aging on the nucleation and growth of precipitates in Al-3 .88%Cu and Al-3.87%Cu-0.56%Mg-0.56%Ag alloys was investigated by electric res istivity measurement and transmission electron microscopy observation. The resul ts indicate that external stress promotes the formation of clusters of solute at oms or GP zones,but retards the growth of θ′ and Ω phases. A critica l phenomenon that the microstructural evolution will be modified at a certain ex ternal extress value is found in Al-Cu-Mg-Ag alloy. The applied external stre ss during aging induces preferentially oriented precipitations of θ′ and Ω in Al-Cu and Al-Cu-Mg-Ag alloys,respectively. The origin of stress- induced orientation effect is understood by analyzing interaction between extern al stress and misfit strain by Eshelby elastic inclusion theory.
Continuous-wave Raman laser in H_2 (1998)

Recent developments in high-finesse cavities now make broadly tunable, continuous-wave Raman lasers possible. The design and preliminary characterization of what is to the authors' knowledge the first continuous-wave Raman laser in H(2) are presented. The threshold is currently at 2 mW of pump, making diode laser pumping possible. The maximum photon conversion efficiency observed was 35% at 7.6 mW of pump power.
Production of a Complete c<scp>DNA</scp> Library (1992)

Abstract A complete cDNA library is one that contains at least one cDNA clone representing each mRNA in the cell. A method is provided in this unit for calculating the required base of a cDNA library such that the library should contain at least one copy of every mRNA. Either a phage or plasmid vector can be used in constructing a complete cDNA library, and protocols are described for both. Procedures for evaluating these cDNA libraries are also provided along with a procedure for evaluating the quality of the λ arms used in constructing complete phage cDNA libraries.
Phase I clinical and pharmacokinetic study of carzelesin (U-80244) given daily for five consecutive days. (1996)

Carzelesin (U-80244), one of the synthetic DNA minor groove binding cyclopropylpyrroloindole analogues, was selected for clinical development because of its high potency, promising antitumor activity in murine solid tumors and leukemia, and significant therapeutic efficacy against colon and rhabdomyosarcoma xenografts. In this Phase I study, carzelesin was given daily for 5 consecutive days to (a) determine the maximum tolerable dose (MTD) and the pattern of toxicity of this schedule; (b) define the pharmacokinetic profile of the parent, as was done for the intermediate compound U-76073 and the DNA-reactive agent U-76074; and (c) document any antitumor activity observed. Carzelesin was given as a 10-min infusion with a constant-rate infusion pump. Treatment was repeated every 4 weeks or when blood counts had recovered to normal values. The starting dose of 12 microgram/m2/day was escalated by 20-30% increments until the MTD (defined as the dose leading to grade 4 hematological or grade 3 nonhematological toxicity in at least two of six patients) was reached. Pharmacokinetic studies were planned on days 1 and 5 of the first cycle in at least two patients per dose level. Plasma levels of carzelesin, U-76073, and U-76074 were determined by high-performance liquid chromatography with UV detection and a detection limit of 0.5 ng/ml. Twenty-five patients were entered in the study, and 56 cycles were evaluable for hematological toxicity. Subsequent dose levels evaluated were 24, 30, 35, and 40 microgram/m2. Both neutropenia and thrombocytopenia were dose limiting and cumulative, with a high interpatient variability. Neutropenia occurred earlier (median time to neutrophil nadir and recovery, 15 and 29 days, respectively) than thrombocytopenia (median time to platelet nadir and recovery, 25 and >/=26 days, respectively); there were delays of treatment because of persisting thrombocytopenia in all patients treated at the MTD. At the MTD, the peak plasma concentrations of carzelesin were achieved at the end of the infusion and were higher than those found cytotoxic in vitro against tumor cell lines. Carzelesin was detectable up to a maximum of 1 h after the infusion. Smaller amounts of U-76073 were detectable for a maximum of 30 min only at the MTD, whereas U-76074 was never found. An 8-month partial remission was reported in one previously untreated patient with hepatocellular carcinoma at 40 microgram/m2. The MTD was fixed at 40 microgram/m2 daily; 35 and 30 microgram/m2 are the daily doses recommended for Phase II studies in good- and poor-risk patients. The daily regimen for 5 days seems to offer no advantage over the single intermittent schedule that has been selected for the Phase II program in Europe.
Contribution of anisotropic velocity distribution of recoil atoms to sputtering yields and angular distributions of sputtered atoms (1981)

Abstract A modified Sigmund's formula is derived, based on the assumption that the transient phenomenon is dominant in low-energy sputtering, i.e., taking into account the anisotropy of the velocity distribution of recoil atoms near the surface. This modified Sigmund's formula is exactly coincident with Matsunami's empirical formula which includes the threshold effect of primary recoil atoms. The same approach is successfully applied to the analysis of the angular distribution of sputtered atoms and a simple formula is also obtained. This simple formula is shown to predict well both the heart-shaped distribution for normal incidence and preferential forward ejection of sputtered atoms for oblique incidence.

Impact of dedicated hemostasis device for distal radial arterial access with an adequate hemostasis protocol on radial arterial observation by ultrasound (2020)

There is no established hemostasis method or protocol for the transdistal radial approach. Therefore, this study aimed to determine whether "the PreludeSYNC DISTAL" radial compression device (PSD; Merit Medical Systems, Inc., South Jordan, UT) can effectively prevent distal radial artery (dRA) occlusion following catheterization procedures. This retrospective study analyzed patients who underwent hemostasis using the PSD from January 1, 2019, to March 31, 2019. The primary endpoint was occlusion or excessive stenosis of the radial artery (RA) 1 month after catheterization. Pulsatile blood flow and vessel diameters of the dRA and forearm RA (fRA) were measured using vascular ultrasound before and 1 month after catheterization to determine arterial damage. Secondary endpoints were achievement of hemostasis, bleeding, hematoma, aneurysm, neurological abnormality, and functional disturbance of the fingers or hand. Fifty patients (mean age, 70.9 ± 10.7 years; male, 72.0%) were enrolled in this study. Complete hemostasis was achieved in all cases. Total hemostasis time was 161 ± 45 min. No procedure-associated complications were noted. Pulsations of the dRA and fRA were maintained at 1 month. No functional disturbance or neurological abnormality was observed. Vessel diameters of the dRA and fRA were not significantly different before and 1 month after catheterization. No dissection, pseudoaneurysm, or occlusion/stenosis was observed on ultrasound. Distal radial access with a unique device and protocol effectively achieved hemostasis and prevented injury and occlusion of the dRA and fRA.
