Effects of anaerobic digester solids retention time on odor emission and dewaterability of biosolids subjected to various shear intensities, polymer doses, and storage duration times (2020)

Shear intensity and polymer dose contributed more than SRT to odor emission from dewatered cake.
Scaling of Berry-curvature monopole dominated large linear positive magnetoresistance (2022)

The linear positive magnetoresistance (LPMR) is a widely observed phenomenon in topological materials, which is promising for potential applications on topological spintronics. However, its mechanism remains ambiguous yet, and the effect is thus uncontrollable. Here, we report a quantitative scaling model that correlates the LPMR with the Berry curvature, based on a ferromagnetic Weyl semimetal CoS<sub>2</sub> that bears the largest LPMR of over 500% at 2 K and 9 T, among known magnetic topological semimetals. In this system, masses of Weyl nodes existing near the Fermi level, revealed by theoretical calculations, serve as Berry-curvature monopoles and low-effective-mass carriers. Based on the Weyl picture, we propose a relation [Formula: see text], with <i>B</i> being the applied magnetic field and [Formula: see text] the average Berry curvature near the Fermi surface, and further introduce temperature factor to both MR/<i>B</i> slope (MR per unit field) and anomalous Hall conductivity, which establishes the connection between the model and experimental measurements. A clear picture of the linearly slowing down of carriers, i.e., the LPMR effect, is demonstrated under the cooperation of the <i>k</i>-space Berry curvature and real-space magnetic field. Our study not only provides experimental evidence of Berry curvature-induced LPMR but also promotes the common understanding and functional designing of the large Berry-curvature MR in topological Dirac/Weyl systems for magnetic sensing or information storage.
Photochemical Cleavage of DNA With Phosphorus(V)porphyrin Derivatives (1994)

Abstract Photocleavage of double-stranded circular DNA was examined using a phosphorus(V)porphyrin derivative. The P(V)porphyrin derivative cleaved the DNA upon visible light irradiation both in air and in argon. Photoreactions through an indirect process with singlet oxygen and a direct electron transfer process were suggested.
Low-temperature plasma simulations with the LSP PIC code (2014)

including a gas switch for high-power AC/DC conversion, a glow discharge and a Hall thruster. Simulation results will be presented with an emphasis on code comparison and validation against experiment. High-voltage, direct-current (HVDC) power transmission is becoming more common as it can reduce construction costs and power losses. Solid-state power-electronics devices are presently used, but it has been proposed that gas switches could become a compact, less costly, alternative. A gas-switch conversion device would be based on a glow discharge, with a magnetically insulated cold cathode. Its operation is similar to that of a sputtering magnetron, but with much higher pressure (0.1 to 0.3 Torr) in order to achieve high current density. We have performed 1D (axial) and 2D (axial/radial) simulations of such a gas switch using LSP. The 1D results were compared with results from the EDIPIC code. To test and compare the collision models used by the LSP and EDIPIC codes in more detail, a validation exercise was performed for the cathode fall of a glow discharge. We will also present some 2D (radial/azimuthal) LSP simulations of a Hall thruster.
A time-of-flight range image sensor using high-speed 4-tap lock-in pixels (2017)

This paper presents a CMOS Time-of-Flight (TOF) range imager using pinned-photodiode based high-speed 4-tap lock-in pixels with lateral-electric-field charge modulators (LEFM) in a 0.11 um CIS process. The proposed lock-in pixel structure using lateral electric field control is suitable for implementing a multiple-tap charge modulator while achieving high-speed charge transfer for high time resolution. The TOF imager with the multiple-tap charge modulators is expected to have background light cancelling capability in one frame and to improve range resolution with the 4 time windows for a range-shifted light pulse. Measurement results of the implemented TOF imager with 160&times;240 pixels are reported.
Determinantes contextuais da coesão do sistema de crenças democrático: evidências a partir da América Latina (2019)

Resumo O presente artigo analisa o impacto de fatores contextuais - o PIB per capita, a qualidade da democracia e os anos ininterruptos de democracia - sobre a coesão do sistema de crenças democrático dos latino-americanos. Considera-se um democrata coeso aquele que apoia diferentes princípios democráticos, notadamente: eleições livres e competitivas, separação dos poderes, primado da lei, participação política e tolerância. Utilizamos, para isso, um modelo multinível com dados de opinião pública de 19 países do Barômetro das Américas de 2010. Os resultados indicam que os cidadãos que vivem em países com maior PIB per capita e maior tradição democrática são mais propensos a serem democratas coesos. A qualidade da democracia, por sua vez, não apresentou resultados significativos. Argumentamos que esses achados têm uma importante implicação para a democracia na região.

Evidence of susceptibility loci on 4q32 and 16p12 for bipolar disorder (2003)

We performed a genome-wide scan for susceptibility loci in bipolar disorder in a study sample colleted from the isolated Finnish population, consisting of 41 families with at least two affected siblings. We identified one distinct locus on 16p12 providing significant evidence for linkage in two-point analysis (Z(max)=3.4). Furthermore, three loci with a two-point LOD score >2.0 were observed with markers on 4q32, 12q23 and Xq25, the latter locus having been earlier identified in one extended Finnish pedigree. In the second stage we fine mapped these chromosomal regions and also genotyped additional family members. In the fine mapping stage, 4q32 provided significant evidence of linkage for the three-point analyses (Z(max)=3.6) and 16p12 produced a three-point LOD score of 2.7. Since the identified chromosomal regions replicate earlier linkage findings in either bipolar disorder or other mental disorders, they should be considered good targets for further genetic analyses.
Dispersed Automation for Industrial Internet of Things (2020)

This position article presents dispersed automation, a novel approach for reprogramming the omnipresent industrial Internet of Things (IIoT) devices in critical infrastructure for the co-execution of general-purpose computation workloads in an optimal and reliable manner. The key observation is that IIoT devices are available in large quantities in critical infrastructure. However, these devices are often underutilized due to the conservative allocation of resources, static task assignment, and lack of exploitation of parallelism. Dispersed automation gives new life to IIoT devices, some of them as powerful as general-purpose computers, and makes them accessible for the co-execution of various computational workloads, while dynamically adapting to different applications and operational environments. Two key contributions make this possible: the use of a domain-specific language and on-channel computation. We present dispersed automation as an enabling technology for the implementation of future smart and adaptive IIoT systems.
Progress toward finding the perfect match: hydrogels for treatment of central nervous system injury (2020)

Injury to the central nervous system remains a significant therapeutic challenge from a tissue engineering perspective because of the soft tissue properties, anatomical and spatial complexities, and highly divergent injury mechanisms that must be addressed. Emerging strategies to approach the difficulties of central nervous system regeneration include the use of hydrogel formulations as scaffolds for cellular and biomolecular delivery. Hydrogels have been used extensively in tissue engineering because they are adaptable to match a number of design considerations to recapitulate native tissues, including their mechanical and biochemical properties. Hydrogel scaffolds are specifically suited for achieving the soft tissue properties of the brain and spinal cord and have much demonstrated evidence for functionalization toward improved neural repair in the central nervous system. This review focuses on developments made in the last five years for advanced hydrogel strategies used in central nervous system repair and regeneration. Specific emphasis is placed on the exploitation of hydrogel properties for enhanced structural, biochemical, and cellular cues for both brain and spinal cord regeneration. Although translational challenges still remain, evidence demonstrates the forward progress in material design and use to validate hydrogels as tissue engineering surrogates for brain and spinal cord injuries.
Contact Angles of Submillimeter Particles:  Connecting Wettability to Nanoscale Surface Topography (2007)

A method is presented for the measurement of contact angles of particles in the size range 100-1000 microm, using an optical microscope. This method is used to characterize the wettability of polyethylene particles produced in a gas-phase polymerization process. The as-polymerized particles are shown to be significantly more hydrophobic than melt-processed polyethylene materials. The surface structure of the particles is examined with scanning electron microscopy, and the increased hydrophobicity of the as-polymerized particles is attributed to the nanoscale texture of the particle surfaces.
Digital Halftoning (1987)

Digital Halftoning addresses the problem of developing algorithms that best match the specific parameters of any target display device. It is the first significant study of the process of producing quality images on practical computer displays. Along with text and graphics, images are fast becoming a generic data type for general-purpose computer systems. This poses new problems for the systems designer, who must be able to preprocess digital image data for a wide variety of video and hard copy displays. Digital halftoning, the method by which the illusion of continuous-tone images are created through the arrangement of binary picture elements, is a key component of any preprocessing. Digital Halftoning addresses the problem of developing algorithms that best match the specific parameters of any target display device. It is the first significant study of the process of producing quality images on practical computer displays. To aid the systems designer, Ulichney devises the concept of blue noise—which has many desirable properties for halftoning—and suggests efficient algorithms for its use. He also introduces new metrics for analyzing the frequency content of periodic and aperiodic patterns for both rectangular and hexagonal grids, and presents a unique "aspect ratio immunity" argument in favor of hexagonal grids. Included are several carefully selected digitally-produced images.
Ultrawideband propagation channels and their impact on system design (2007)

The performance of ultrawideband (UWB) communications systems is determined by the propagation channels they operate in. This paper gives an overview of UWB channels and their impact on system design. The emphasis lies on (i) multiple-antenna systems and (ii) body-area networks. We discuss the frequency dependence of angular power spectra and show that spatial multiplexing can be used for achieving very high data rates in MIMO-UWB systems. For body-area networks, we And small delay spreads, so that high-rate communications can be supported with relatively simple receiver structures. Finally, we argue that the clustering structure and "soft onset" property of UWB power delay profiles strongly influence the design of ranging systems.
Charge Transport Physics of Conjugated Polymer Field‐Effect Transistors (2010)

Abstract Field‐effect transistors based on conjugated polymers are being developed for large‐area electronic applications on flexible substrates, but they also provide a very useful tool to probe the charge transport physics of these complex materials. In this review we discuss recent progress in polymer semiconductor materials, which have brought the performance and mobility of polymer devices to levels comparable to that of small‐molecule organic semiconductors. These new materials have also enabled deeper insight into the charge transport physics of high‐mobility polymer semiconductors gained from experiments with high charge carrier concentration and better molecular‐scale understanding of the electronic structure at the semiconductor/dielectric interface.
Arabidopsis poly(A) polymerase PAPS1 limits founder‐cell recruitment to organ primordia and suppresses the salicylic acid‐independent immune response downstream of EDS1/PAD4 (2013)

Polyadenylation of pre-mRNAs by poly(A) polymerase (PAPS) is a critical process in eukaryotic gene expression. As found in vertebrates, plant genomes encode several isoforms of canonical nuclear PAPS enzymes. In Arabidopsis thaliana these isoforms are functionally specialized, with PAPS1 affecting both organ growth and immune response, at least in part by the preferential polyadenylation of subsets of pre-mRNAs. Here, we demonstrate that the opposite effects of PAPS1 on leaf and flower growth reflect the different identities of these organs, and identify a role for PAPS1 in the elusive connection between organ identity and growth patterns. The overgrowth of paps1 mutant petals is due to increased recruitment of founder cells into early organ primordia, and suggests that PAPS1 activity plays unique roles in influencing organ growth. By contrast, the leaf phenotype of paps1 mutants is dominated by a constitutive immune response that leads to increased resistance to the biotrophic oomycete Hyaloperonospora arabidopsidis and reflects activation of the salicylic acid-independent signalling pathway downstream of ENHANCED DISEASE SUSCEPTIBILITY1 (EDS1)/PHYTOALEXIN DEFICIENT4 (PAD4). These findings provide an insight into the developmental and physiological basis of the functional specialization amongst plant PAPS isoforms.
Comprehensive Assessment of Genetic and Molecular Features Predicting Outcome in Patients With Chronic Lymphocytic Leukemia: Results From the US Intergroup Phase III Trial E2997 (2007)

These results support the use of interphase cytogenetic analysis, but not IgVH, CD38 expression, or ZAP-70 status, to predict outcome of FL-based chemotherapy. Patients with high-risk cytogenetic features should be considered for alternative therapies.
Brain reserve contributes to distinguishing preclinical Alzheimer’s stages 1 and 2 (2023)

These data indicate that HCs and stages 1 and 2 do not correspond to linear brain volume reduction. Instead, stage 1 is associated with larger than expected volumes of hippocampal subfields in the face of amyloid pathology. This indicates a brain reserve mechanism in stage 1 that enables individuals with amyloid pathologic change to be cognitively normal and asymptomatic without subjective cognitive decline.
A nonlinear lowpass filter that eliminates peak attenuation (2002)

Linear-phase lowpass filters are often used as a preprocessing step in signal processing applications to eliminate high frequency components of noise that do not overlap with the signal spectrum. Signals with sharp peaks confound this type of noise reduction because sharp peaks have a broad spectrum and are significantly attenuated by lowpass filters. This paper describes a simple method that restores the signal peaks to their full amplitude by adding a filtered estimate of the peak residuals to the original lowpass filter output. Examples are given of the nonlinear filter applied to a Poisson process, an electrocardiogram, and an extracellular microelectrode recording of neuron action potentials.
Microviscosity in poly(ethylene oxide)‐polypropylene oxide‐poly(ethylene oxide) block copolymers probed by fluorescence depolarization kinetics (2002)

Abstract Triblock copolymers [poly(ethylene oxide) (PEO) and polypropylene oxide (PPO)], Pluronic F127 with 100 PEO blocks on each end, and 65 blocks of PPO in the center were examined in aqueous solution. The “sol” and “gel” phase diagram was determined as a function of concentration and temperature. For further study, the concentration was fixed at 20 wt %, and the temperature dependence of the dynamic viscosity differed from the temperature dependence of fluorescence emission spectra and the microviscosity probed by the fluorescence depolarization kinetics of rhodamine 123 dye, which was dissolved in the continuous hydrophilic phase. The depolarization measurements used single‐photon counting after two‐photon excitation with a Ti‐sapphire femtosecond laser. Although the viscoelastic modulus increased by an order of magnitude when the sol‐to‐gel transition was crossed, the microviscosity of the hydrophilic continuous medium showed only minor changes. At different temperatures the fluorescence lifetime was the same with a single‐exponential time constant, but the fluorescence depolarization displayed a double‐exponential decay. After comparison with fluorescence depolarization of the dye in PPO melt and PEO whose molecular weight and aqueous concentrations were varied, the relative proportions of faster and slower components of the fluorescence depolarization were tentatively attributed to varying ratios of the dye in free solution and associated with micelles. © 2002 Wiley Periodicals, Inc.

Dissipative Optomechanical Preparation of Macroscopic Quantum Superposition States (2016)

The transition from quantum to classical physics remains an intensely debated question even though it has been investigated for more than a century. Further clarifications could be obtained by preparing macroscopic objects in spatial quantum superpositions and proposals for generating such states for nanomechanical devices either in a transient or a probabilistic fashion have been put forward. Here, we introduce a method to deterministically obtain spatial superpositions of arbitrary lifetime via dissipative state preparation. In our approach, we engineer a double-well potential for the motion of the mechanical element and drive it towards the ground state, which shows the desired spatial superposition, via optomechanical sideband cooling. We propose a specific implementation based on a superconducting circuit coupled to the mechanical motion of a lithium-decorated monolayer graphene sheet, introduce a method to verify the mechanical state by coupling it to a superconducting qubit, and discuss its prospects for testing collapse models for the quantum to classical transition.
Utility ofCD54,CD229, andCD319 for the identification of plasma cells in patients with clonal plasma cell diseases (2015)

From the three markers evaluated, CD229 may be considered as the most reliable marker to replace CD38 or CD138 for the identification of PCs in patients undergoing anti-CD38 or anti-CD138 therapy, until a better alternative is available.
Room temperature negative differential resistance of a monolayer molecular rotor device (2009)

An electrically driven molecular rotor device comprised of a monolayer of redox-active ligated copper compounds sandwiched between a gold electrode and a highly doped P+Si substrate was fabricated. Current-voltage spectroscopy revealed a temperature-dependent negative differential resistance (NDR) associated with the device. Time-dependent density functional theory suggests the source of the observed NDR to be redox-induced ligand rotation around the copper metal center, an explanation consistent with the proposed energy diagram of the device. An observed temperature dependence of the NDR behavior further supports this hypothesis.
Prolonged SARS-CoV-2 RNA virus shedding and lymphopenia are hallmarks of COVID-19 in cancer patients with poor prognosis (2021)

Patients with cancer are at higher risk of severe coronavirus infectious disease 2019 (COVID-19), but the mechanisms underlying virus-host interactions during cancer therapies remain elusive. When comparing nasopharyngeal swabs from cancer and noncancer patients for RT-qPCR cycle thresholds measuring acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in 1063 patients (58% with cancer), we found that malignant disease favors the magnitude and duration of viral RNA shedding concomitant with prolonged serum elevations of type 1 IFN that anticorrelated with anti-RBD IgG antibodies. Cancer patients with a prolonged SARS-CoV-2 RNA detection exhibited the typical immunopathology of severe COVID-19 at the early phase of infection including circulation of immature neutrophils, depletion of nonconventional monocytes, and a general lymphopenia that, however, was accompanied by a rise in plasmablasts, activated follicular T-helper cells, and non-naive Granzyme B<sup>+</sup>FasL<sup>+</sup>, Eomes<sup>high</sup>TCF-1<sup>high</sup>, PD-1<sup>+</sup>CD8<sup>+</sup> Tc1 cells. Virus-induced lymphopenia worsened cancer-associated lymphocyte loss, and low lymphocyte counts correlated with chronic SARS-CoV-2 RNA shedding, COVID-19 severity, and a higher risk of cancer-related death in the first and second surge of the pandemic. Lymphocyte loss correlated with significant changes in metabolites from the polyamine and biliary salt pathways as well as increased blood DNA from Enterobacteriaceae and Micrococcaceae gut family members in long-term viral carriers. We surmise that cancer therapies may exacerbate the paradoxical association between lymphopenia and COVID-19-related immunopathology, and that the prevention of COVID-19-induced lymphocyte loss may reduce cancer-associated death.
