Investigation of Optimum Double Codebook Design for Downlink MIMO in LTE-A (2011)

Due to the limited feedback amount, the codebook and feedback design is very important. In order to achieve better tradeoff between overhead and performance, the double codebook structures are proposed and discussed, where a final precoder W is determined by two precoders W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> and W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> , which are selected from two different codebooks. In this paper, we give an overview of several double codebook structures and evaluate them based on system level simulations (SLS). We consider two frameworks to determine a final precoder: W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> and W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> where W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> and W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> track long-term/wideband and short term/subband channel properties, respectively. It is shown that under 4Tx assumption, double codebooks achieve gains compared with Rel.8 codebook when considering the multi-user (MU) MIMO and do not suffer in the case of single-user (SU) MIMO. Both W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> and W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> provide nearly the same gains over that for the Rel. 8 codebook with uniform linear array (ULA) deployment.

Preparation of microflake ink for low cost printing of CIS-Se absorber layers (2012)

Mechanical alloying and bead milling techniques were used for the low cost preparation of precursor inks for printing CIS-Se absorber layers. The plate shaped microflake particle precursor is composed of nanostructured elemental Copper-Indium-Sulfur and Selenium. The high aspect ratio microflakes have a typical thickness around 200 nm and a diameter of 1-5 μm. The plate shape of the microflakes facilitates the deposition of a high quality film during the coating process. Moreover, the nanostructured nature of the microflakes improves the sintering behavior during selenization. The milling technique is relatively low cost, easily up-scalable, fast and very flexible in targeted composition.
A Cationic Metal–Organic Framework to Scavenge Cell-Free DNA for Severe Sepsis Management (2021)

Circulating cell-free DNA (cfDNA) released by damaged cells causes inflammation and has been associated with the progression of sepsis. One proposed strategy to treat sepsis is to scavenge this inflammatory circulating cfDNA. Here, we develop a cfDNA-scavenging nanoparticle (NP) that consists of cationic polyethylenimine (PEI) of different molecular weight grafted to zeolitic imidazolate framework-8 (PEI-<i>g</i>-ZIF) in a simple one-pot process. PEI<i>-g-</i>ZIF NPs fabricated using PEI 1800 and PEI 25k but not PEI 600 suppressed cfDNA-induced TLR activation and subsequent nuclear factor kappa B pathway activity. PEI 1800-<i>g</i>-ZIF NPs showed greater inhibition of cfDNA-associated inflammation and multiple organ injury than naked PEI 1800 (lacking ZIF), and had greater therapeutic efficacy in treating sepsis. These results indicate that PEI<i>-g-</i>ZIF NPs acts as a "nanotrap" that improves upon naked PEI in scavenging circulating cfDNA, reducing inflammation, and reversing the progression of sepsis, thus providing a novel strategy for sepsis treatment.
Human recombinant interleukin 1 stimulates collagenase and prostaglandin E2 production by human synovial cells. (1986)

The pathogenesis and progression of rheumatoid arthritis involves the production of biologically active lymphokines and monokines. Of these, interleukin 1 (IL-1) has been somewhat of a controversial molecule because it seems to evoke various biological responses in several different tissues. In these studies we demonstrate that three biological properties of human monocyte-derived IL-1 (T-lymphocyte activation and human synovial cell prostaglandin E2 and collagenase production) co-purify. The complementary DNA for the prominent pI 7 form of human IL-1 was expressed, purified, and tested. Any controversy now appears resolved since homogeneous recombinant human IL-1 stimulates prostaglandin E2 and collagenase from human synovial cells as well as activates T cells in vitro.
Chaotic advection in a three-dimensional volume-preserving potential flow (2017)

While mixing and particle transport in 2D incompressible flows are well-understood, much less is known about 3D incompressible flows. This is because the addition of a third dimension adds to the topological complexity, and more importantly, the link between 2D incompressible flows and Hamiltonian systems that proved so fruitful breaks down for 3D flows. Therefore, there is a need for fundamental studies on 3D fluid transport and mixing, with applications in groundwater flows, micro-fluidics, industrial mixers and biological flows. Here fluid transport and mixing is studied using a model fluid flow, the 3D Reoriented Potential Mixing (3DRPM) flow, as a case study to reveal novel transport mechanisms and associated coherent structures that are generic to 3D volume-preserving flows. The 3DRPM flow consists of a periodically reoriented dipole flow, and is a 3D analogue of the 2D RPM flow that has been studied in the past. In the 3DRPM flow it is found that there are a number of competing transport mechanisms, that together drive a transition from 1D to 3D particle transport. Periodic points and lines play an important role for all volume-preserving flows, revealing regions of chaos and impenetrable barriers to transport. Here it is shown that degenerate/parabolic periodic points are particularly important, as they represent bifurcations in flow stability. Conversely, discontinuous deformations are an unexpected consequence of dipole reorientation, akin to slip deformations seen in shear-banding materials, and occur even though the steady dipole flow is smooth. This has a significant impact on the transport behaviour of particles, and can either enhance or impede the rate of mixing. The combination of smooth and discontinuous deformations is generic to a wide range of systems, including flows with extraction and reinjection of fluid, granular flows, and deformations of shear-banding materials. Here it is shown that discontinuous deformations can destroy impenetrable barriers to transport, allowing greater freedom for particle transport. In 3D systems they can create a novel mechanism for fully 3D transport that is similar in effect to Resonance Induced Dispersion.
Removing residual shot noise by phase sequencing in marine vibrators (2017)

In a marine seismic survey using airguns the reverberant noise left over from previous shots (the residual shot noise) typically mandates the use of shot-time intervals that are longer than would be ideal on shot spatial sampling grounds alone. When a marine vibrator seismic source is used the phase of the emitted signal can be chosen at will. In particular, it can change from one shot to the next in a ‘phase sequence’. Phase sequencing can be used to move energy about in the frequency-wavenumber space in the common-receiver domain. In this abstract we describe one application of phase sequencing in which the residual shot noise is moved into a part of the frequency-wavenumber domain where there is no signal. The noise can then be removed without affecting the signal. This allows the shot-time interval to be reduced. Phase sequencing techniques can also be employed to enable simultaneous sources of high multiplicity. Phase sequencing cannot be directly used with airguns because we have no control of the phase of the airgun signal; control is limited to simple changes of amplitude and overall time delay.

Characterization of the Protective Immune Responses Conferred by Recombinant BCG Overexpressing Components of Mycobacterium tuberculosis Sec Protein Export System (2022)

<i>Mycobacterium bovis</i> Bacillus Calmette-Guérin (BCG) is the only approved vaccine against tuberculosis (TB). However, its efficacy in preventing pulmonary TB in adults is limited. Despite its variable efficacy, BCG offers a number of unique and beneficial characteristics, which make it suitable as a vaccine vehicle to express recombinant molecules. In <i>Mycobacterium tuberculosis</i>, the general Sec pathway is an essential cellular process, and it is responsible for exporting the majority of proteins across the cytoplasmic membrane, including potent immune-protective antigens, such as members of the antigen 85 (Ag85) complex. We engineered BCG to overexpress the <i>M. tuberculosis</i> SecDFG proteins in order to improve the efficiency of the Sec-dependent export system and, thus, enhance the secretion of immunogenic proteins. BCG<sup>SecDFG</sup> displayed increased intracellular survival within macrophages in vitro and greater persistence in the lymphoid organs of vaccinated mice than parental BCG. In addition, vaccination with BCG<sup>SecDFG</sup> generated higher numbers of IFN-γ-secreting T cells in response to secreted mycobacterial antigens compared to BCG, particularly members of the Ag85 complex. Furthermore, vaccination with BCG<sup>SecDFG</sup> significantly reduced the bacterial load in the lungs and spleens of <i>M. tuberculosis</i>-infected mice, which was comparable to the protection afforded by parental BCG. Therefore, the modification of protein secretion in BCG can improve antigen-specific immunogenicity.
Hofmeister Effects on Poly(NIPAM) Microgel Particles: Macroscopic Evidence of Ion Adsorption and Changes in Water Structure (2006)

The term Hofmeister effects is broadly used to refer to ionic specificities in many different physical, chemical and biological phenomena. The origin of this ionic specificity is sought in two interdependent microscopic sources: 1) the peculiarities of the solvent structure near surfaces and around the ions, and 2) specific ion adsorption-exclusion mechanisms near a surface. In this work, Hofmeister effects on poly(N-isopropylacrylamide) [poly(NIPAM)]-based microgels are examined. Poly(NIPAM) particles are thermally sensitive microgels exhibiting volume-phase transitions with temperature. This temperature-sensitive system seems to be suitable for the independent observation of the two microscopic sources of Hofmeister effects. On the one hand, volume-phase transition, evaluated by photon correlation spectroscopy (PCS), gives information about how the presence of ions changes the water structure around the poly(NIPAM) chains. On the other hand, electrokinetic studies show relevant data about ionic adsorption-exclusion phenomena at the polymer surface.
Continuous Wave Operation of GaN Vertical Cavity Surface Emitting Lasers at Room Temperature (2012)

We report on continuous wave lasing characteristics of GaN vertical cavity surface emitting lasers (VCSELs). The VCSEL operates at room temperature under current injection by using highly reflective distributed Bragg reflectors (DBRs) made up of transparent <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">${\rm ZrO}_{2}$</tex></formula> and <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex Notation="TeX">${\rm SiO}_{2}$</tex></formula> film stacks.

The spacing of the lasing modes shows a clear dependence of the actual cavity lengths with fairly good agreement to theory taking account of the refractive index dispersion.

Evaluation of 10MeV proton irradiation on 5.5 Mpixel scientific CMOS image sensor (2010)

We evaluate the effects of 10 MeV proton irradiation on the performance of a 5.5 Mpixel scientific grade CMOS image sensor based on a 5T pixel architecture with pinned photodiode and transfer gate. The sensor has on-chip dual column level amplifiers and 11-bit single slope analog to digital converters (ADC) for high speed readout and wide dynamic range. The operation of the sensor is programmable and controlled by on-chip digital control modules. Since the image sensor features two identical halves capable of operating independently, we used a mask to expose only one half of the sensor to the proton beam, leaving the other half intact to serve as a reference. In addition, the pixel array and the digital logic control section were irradiated separately, at dose rates varying from 4 rad/s to 367 rad/s, for a total accumulated dose of 146 krad(Si) to assess the radiation effects on these key components of the image sensor. We report the resulting damage effects on the performance of the sensor including increase in dark current, temporal noise, dark spikes, transient effects and latch-up. The dark signal increased by about 55 e-/pixel after exposure to 14 krad (Si) and the dark noise increased from about 2.75e- to 6.5e-. While the number of hot pixels increased by 6 percent and the dark signal non uniformity degraded, no catastrophic failure mechanisms were observed during the tests, and the sensor did not suffer from functional failures.
Mastering the interface for advanced all-solid-state lithium rechargeable batteries (2016)

A solid electrolyte with a high Li-ion conductivity and a small interfacial resistance against a Li metal anode is a key component in all-solid-state Li metal batteries, but there is no ceramic oxide electrolyte available for this application except the thin-film Li-P oxynitride electrolyte; ceramic electrolytes are either easily reduced by Li metal or penetrated by Li dendrites in a short time. Here, we introduce a solid electrolyte LiZr<sub>2</sub>(PO4)<sub>3</sub> with rhombohedral structure at room temperature that has a bulk Li-ion conductivity σ<sub>Li</sub> = 2 × 10<sup>-4</sup> S⋅cm<sup>-1</sup> at 25 °C, a high electrochemical stability up to 5.5 V versus Li<sup>+</sup>/Li, and a small interfacial resistance for Li<sup>+</sup> transfer. It reacts with a metallic lithium anode to form a Li<sup>+</sup>-conducting passivation layer (solid-electrolyte interphase) containing Li<sub>3</sub>P and Li<sub>8</sub>ZrO<sub>6</sub> that is wet by the lithium anode and also wets the LiZr<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> electrolyte. An all-solid-state Li/LiFePO<sub>4</sub> cell with a polymer catholyte shows good cyclability and a long cycle life.
Role of cytokines and growth factors in the induced synthesis of proteinase inhibitors belonging to acute phase proteins. (1991)

The effects of various cytokines on synthesis and secretion of albumin and some proteinase inhibitors belonging to the class of macroglobulins, serpins and cysteine proteinase inhibitors were studied in the primary cultures of rat and mouse hepatocytes and established human hepatoma cell line Hep G2. In all tested systems interleukin 6 depressed the synthesis of albumin and enhanced the synthesis of antichymotrypsin (or contrapsin) and alpha-1-proteinase inhibitor, while in the rat alpha-2-macroglobulin and T-kininogen (thiostatin) were the major acute phase reactants. Smaller and variable effects were observed with interleukin-1, tumour necrosis factor, interferon-gamma, transforming growth factor-beta and epidermal growth factor. Searching for the feed-back regulatory mechanism responsible for induced synthesis of proteinase inhibitors we found that cultured human lung fibroblasts exposed to human alpha-1-antichymotrypsin or antichymotrypsin-cathepsin G complexes produce significantly more interleukin 6 which stimulates Hep G2 cells to augmented synthesis of several acute phase proteins.

In Vitro and In Vivo Antileukemic Effects of the mTOR-Targeting Drug Rapamycin in Patients with Imatinib-Resistant CML. (2005)

Abstract The mammalian target of rapamycin (mTOR) has been described to be activated in BCR/ABL-transformed cells and to mediate rapamycin-induced inhibition of cell growth. We have recently shown that rapamycin downregulates expression of vascular endothelial growth factor (VEGF), a mediator of leukemia-associated angiogenesis, in primary CML cells. In the current study, we analyzed growth-inhibitory in vitro- and in vivo effects of rapamycin in leukemic cells in patients with imatinib-resistant CML, and asked, whether the rapamycin-induced suppression of VEGF in these cells is related to growth-inhibition. Rapamycin dose-dependently inhibited the in vitro growth of primary CML cells in all pts with imatinib-resistant CML tested (rapamycin, 10 nM: 50±17% of control; p&amp;lt;0.05). Moreover, rapamycin was found to downregulate growth of Ba/F3 cells exhibiting wild type (wt) BCR/ABL or various imatinib-resistant mutants of BCR/ABL including the T315I-mutation, which renders BCR/ABL resistant against tyrosine kinase inhibitors. We also found that rapamycin and imatinib exert synergistic inhibitory effects on growth of Ba/F3p210WT cells as well as on Ba/F3 cells containing imatinib-resistant mutants of BCR/ABL. In all cells tested including imatinib-resistant primary cells, rapamycin was found to downregulate expression of VEGF mRNA and secretion of the VEGF protein. However, exogenously added VEGF did not counteract the rapamycin-induced decrease in proliferation suggesting that these two effects of rapamycin are separable. In a consecutive phase of the project, we treated 7 pts with imatinib-resistant CML with rapamycin at 2 mg per os daily for 14 consecutive days, with dose-adjustment allowed to reach a target serum rapamycin concentration of 10–20 ng/ml. A major leukocyte response with decrease from &amp;gt;20,000 to normal values (&amp;lt;10,000/μL) was obtained in 3 pts, and a minor transient response in 2 other pts, whereas 2 pts did not respond. No molecular or cytogenetic responses were seen. No severe side effects of rapamycin were recorded. In aggregate, rapamycin may be an interesting targeted drug in imatinib-resistant CML. However, combinations with other targeted (or conventional) drugs may be required to obtain sufficient antileukemic activity in vivo.
Deep Compositional Denoising for High‐quality Monte Carlo Rendering (2021)

Abstract We propose a deep‐learning method for automatically decomposing noisy Monte Carlo renderings into components that kernel‐predicting denoisers can denoise more effectively. In our model, a neural decomposition module learns to predict noisy components and corresponding feature maps, which are consecutively reconstructed by a denoising module. The components are predicted based on statistics aggregated at the pixel level by the renderer. Denoising these components individually allows the use of per‐component kernels that adapt to each component's noisy signal characteristics. Experimentally, we show that the proposed decomposition module consistently improves the denoising quality of current state‐of‐the‐art kernel‐predicting denoisers on large‐scale academic and production datasets.
