KS0andΛProduction in Pb-Pb Collisions atsNN=2.76  TeV (2013)

The ALICE measurement of K(S)(0) and Λ production at midrapidity in Pb-Pb collisions at √(s(NN))=2.76 TeV is presented. The transverse momentum (p(T)) spectra are shown for several collision centrality intervals and in the p(T) range from 0.4 GeV/c (0.6 GeV/c for Λ) to 12 GeV/c. The p(T) dependence of the Λ/K(S)(0) ratios exhibits maxima in the vicinity of 3 GeV/c, and the positions of the maxima shift towards higher p(T) with increasing collision centrality. The magnitude of these maxima increases by almost a factor of three between most peripheral and most central Pb-Pb collisions. This baryon excess at intermediate p(T) is not observed in pp interactions at √s=0.9 TeV and at √s=7 TeV. Qualitatively, the baryon enhancement in heavy-ion collisions is expected from radial flow. However, the measured p(T) spectra above 2 GeV/c progressively decouple from hydrodynamical-model calculations. For higher values of p(T), models that incorporate the influence of the medium on the fragmentation and hadronization processes describe qualitatively the p(T) dependence of the Λ/K(S)(0) ratio.

Vapor‐Fed Electrolyzers for Carbon Dioxide Reduction Using Tandem Electrocatalysts: Cuprous Oxide Coupled with Nickel‐Coordinated Nitrogen‐Doped Carbon (2022)

Abstract Ethylene is particularly attractive due to its major importance as a feedstock for various applications including the polymer industry. As such, catalyst and electrolyzer developments are crucial to achieve industrially relevant ethylene production and efficiency levels. Here, a tandem electrocatalyst composed of copper nanocubes and nickel‐coordinated nitrogen‐doped carbon (NiNC) is presented, which is integrated into gas diffusion electrodes (GDEs) for direct conversion of vapor‐fed CO 2 into ethylene. Evaluation of tandem GDEs in the vapor‐fed flow electrolyzer shows significantly increased ethylene selectivity in terms of faradaic efficiency and C 2 H 4 /CO ratio compared to a non‐tandem copper GDE. The enhancements are attributed to the increased local CO availability near the copper surface via effective CO 2 to CO conversion on neighboring NiNC. The experimental results are validated by 3D resolved continuum simulations, which show increased flux of higher‐order products with the added CO flux from NiNC. The practical viability of Cu/NiNC catalyst is further evaluated in a membrane electrode assembly electrolyzer, achieving 40% FE toward ethylene at 150 mA cm −2 and 3.2 V. These findings highlight the high selectivity and formation rate of ethylene achieved by successful device integration of the Cu/NiNC catalyst, demonstrating the potential for implementation in large‐scale sustainable CO 2 electrolyzers.

Robust refraction statics solution using feedback from reflection data (2017)

Near surface models from refraction inversion contain several types of errors, which are partially compensated later in the data flow by reflection residual statics. In this work, we modify the dataflow to automatically include feedback information from reflection statics from stack-power maximization. This technique can work with any model based refraction solutions including grid based tomography model and layer based delay time methods. In this report we modify cost function of the refraction inversion by adding model and data weights computed from the long wavelength components of surface consistent residual statics. By using an iterative inversion, these weights allow us to update the near surface velocity model and to reject first arrival picks that do not fit the updated model. In this non-linear optimization work flow the refraction model is derived from maximizing the coherence of the reflection energy and minimizing the misfit between model arrival times and the recorded first arrival times. This approach can alleviate inherent limitations in shallow refraction data by using coherent reflection data.

Structure of a Class C GPCR Metabotropic Glutamate Receptor 1 Bound to an Allosteric Modulator (2014)

The excitatory neurotransmitter glutamate induces modulatory actions via the metabotropic glutamate receptors (mGlus), which are class C G protein-coupled receptors (GPCRs). We determined the structure of the human mGlu1 receptor seven-transmembrane (7TM) domain bound to a negative allosteric modulator, FITM, at a resolution of 2.8 angstroms. The modulator binding site partially overlaps with the orthosteric binding sites of class A GPCRs but is more restricted than most other GPCRs. We observed a parallel 7TM dimer mediated by cholesterols, which suggests that signaling initiated by glutamate's interaction with the extracellular domain might be mediated via 7TM interactions within the full-length receptor dimer. A combination of crystallography, structure-activity relationships, mutagenesis, and full-length dimer modeling provides insights about the allosteric modulation and activation mechanism of class C GPCRs.
A 250-mW 60-GHz CMOS Transceiver SoC Integrated With a Four-Element AiP Providing Broad Angular Link Coverage (2019)

In this article, we present a low-power, small formfactor, 60-GHz packaged radio featuring broad beam coverage. We increase angular coverage by beam switching between two orthogonally pointed low directivity beams that are created using two different antennas integrated in package. The resulting wide angular coverage of the radio makes radio links robust to movement and rotation; this improvement overcomes a key challenge for millimeter-wave (mmWave) deployment in portable electronics. We incorporate a 3.2 mm × 3.2 mm 32-nm CMOS radio integrated circuit (IC) in the package for radio functions. The IC includes TX and RX RF front ends, upand down-conversion mixers, TX and RX analog baseband circuits, a common PLL, TX and RX LO chains, and ADCs and a micro-controller for built-in self-test (BIST). The IC is flip-chip packaged on a fourlayer organic package comprising two TX antennas and two RX antennas. In board-level over-the-air measurements of the half-duplex packaged radio, 17.1-dBm effective isotropic radiated power (EIRP) and 6.1-dB noise figure are achieved in the TX and RX modes respectively, with power consumption below 250 mW in either mode. We characterized the radio over the air using 802.11ad waveforms; the radio is 802.11ad compliant in both TX and RX modes at data rates up to the maximum 802.11ad PHY rate of 4.62 Gb/s (raw data rate >7 Gb/s) with a TX EVM <; -22 dB and RX sensitivity <; -54 dBm. To measure angular coverage, we characterized 802.11ad compliance in 3-D over 3π steradians in first-of-a-kind measurements. The radio maintains 802.11ad compliance over 2.9π steradians solid angle.
Ein neuer Zugang zu 2,6,6‐Trimethylcyclohexa‐2,4‐dienon aus 4‐Oxoisophoron (1989)

A New Access to 2,6,6‐Trimethylcyclohexa‐2,4‐dienone from 4‐Oxoisophorone 2,6,6‐Trimethylcyclohexa‐2,4‐dienone ( 1 ), a versatile starting material for the preparation of some carotenoids and several natural products, was efficiently (73% yield) prepared from oxoisophorone 3 . After conversion of 3 to the alcohol 4 or the acetate 5 , H 2 O was eliminated ( 4→1 ) under acidic distillative conditions, whereas AcOH could be eliminated ( 5→l ) under Pd(O) catalysis.

Biopsy and surgical specimen specific deep learning models for prostate cancer detection on digitized pathology images (2023)

The detection of prostate cancer within H&amp;E-stained tissue slides helps identify the presence, location, and extent of the disease. Machine learning approaches have been developed to accomplish this task for biopsies and radical prostatectomies. Deep learning approaches, primarily using convolutional neural networks (CNN), have demonstrated substantial ability to identify cancer in each of these sample types. Some models trained on biopsies have even been approved for clinical application. Biopsies are small tissue samples acquired through a syringe to establish cancer diagnosis while radical prostatectomies are large planar sections of prostate tissue acquired post-surgery. This leads to differing morphology and heterogeneity between sample types, making it unclear whether algorithms trained on biopsies are robust enough to perform well on radical prostatectomies and vice versa. Our goal was to investigate whether morphological differences between sample types affected the performance of radical prostatectomy trained CNN models when applied to biopsies and vice versa. Radical prostatectomies (N=100) and biopsies (N=50) were acquired from The University of Pennsylvania to train (80%) and validate (20%) a CNN using the Densenet architecture for biopsies (M<sup>B</sup>), radical prostatectomies (M<sup>R</sup>), and a combined dataset (M<sup>B+R</sup>). Model performance was compared using sensitivity, specificity, and F1 score. To isolate the effect of morphological differences on performance, we acquired all data from the same institution, ensured no batch effects were present via UMAP, applied data augmentation during training, and applied stain normalization. Additionally, the radical prostatecomy training set was optimized for transfer to biopsies by reducing heterogeneity (M<sup>R*</sup>). This reduction was based on distance from the centroid of a texture feature distribution. Models performed well when applied to their own sample type (F1 &gt; 0.88) but performed poorly when applied across sample types (F1 &lt; 0.65). Reducing heterogeneity to optimize the radical prostatectomy training set resulted in M<sup>R*</sup> (F1=0.72) noticeably outperforming M<sup>R</sup> (F1=0.53) on biopsies. This indicates that differences in morphology and heterogeneity drive performance differences between cancer detection models trained on different sample types. Our results suggest that these morphological differences can be overcome with sample type specific models or training set optimization methods.
Diffuse Optical Tomography for Breast Cancer Imaging: Optimal Clinical Design for Sensitivity and Image Accuracy (2000)

Diffuse optical tomography can be used to accurately reconstruct images of the human breast, and can provide functional information about hemoglobin concentration and oxygen saturation. This study examines the influences of source-detector geometry upon image recovery and explicitly evaluates the detectability of objects at varying contrasts, as well as the accuracy with which the optical properties of those objects can be determined. Results from a clinical prototype optical imager will be shown to illustrate typical image quality. Case examples highlight where improvements in image quality can be made.
Selective changes in the neurofilament and microtubule cytoskeleton of NF‐H/LacZ mice (2002)

This study focused mainly on changes in the microtubule cytoskeleton in a transgenic mouse where beta-galactosidase fused to a truncated neurofilament subunit led to a decrease in neurofilament triplet protein expression and a loss in neurofilament assembly and abolished transport into neuronal processes in spinal cord and brain. Although all neurofilament subunits accumulated in neuronal cell bodies, our data suggest an increased solubility of all three subunits, rather than increased precipitation, and point to a perturbed filament assembly. In addition, reduced neurofilament phosphorylation may favor an increased filament degradation. The function of microtubules seemed largely unaffected, in that tubulin and microtubule-associated proteins (MAP) expression and their distribution were largely unchanged in transgenic animals. MAP1A was the only MAP with a reduced signal in spinal cord tissue, and differences in immunostaining in various brain regions corroborate a relationship between MAP1A and neurofilaments.
Testosterone Antagonizes Doxorubicin‐Induced Senescence of Cardiomyocytes (2016)

Testosterone protects cardiomyocytes against senescence caused by doxorubicin at least in part by modulating telomere binding factor 2 via a pathway involving the androgen receptor, phosphatidylinositol 3 kinase, AKT, and nitric oxide synthase 3. This is a potential mechanism by which pubescent and adolescent boys are less prone to chronic anthracycline cardiotoxicity than girls.

Nanometer-Thick Mn:NiO and Co:NiO Films for High Performance Nonenzymatic Biosensors (2021)

People with diabetes require regular blood sugar level monitoring, using commercial enzyme-based biosensors. There is a considerable need to develop biosensors with nonenzymatic electrodes to eliminate the drawbacks of enzymes. Nanostructured nickel oxide (NiO) thin films are highly promising materials for the development of nonenzymatic glucose and hydrogen peroxide (H2O2) biosensors. Although the biosensor performance can be easily attained with nonenzymatic electrodes, their commercialization still requires development of cost-effective and mass-production methods. In this work, we demonstrate the use of ultrasonic spray deposited, nanometer-thick, manganese and cobalt doped NiO (Mn:NiO and Co:NiO) films on indium tin oxide (ITO) coated glass substrates for glucose sensing. Sensor characterization followed detailed materials characterization. Nanometer-thick Co:NiO film electrodes showed better glucose sensor performance than those of bare NiO and Mn:NiO electrodes. High sensitivity of 1.67 μA/μM·cm2, a low detection limit of 231 nM, and a fast response time of 5.4 s within the linear range of 16–308 μM were obtained from nanometer-thick Co:NiO film electrodes. Amperometric measurements showed significant electrode reproducibility and stability. Nanometer-thick Co:NiO film electrode was also used to demonstrate actual clinical glucose measurements using human blood serum as a glucose source. Moreover, all fabricated nanometer-thick film electrodes were also utilized as H2O2 sensors. This work provides a novel approach for monitoring the biosensor performance using nanometer-thick doped NiO film electrodes. Obtained results demonstrated the potential of ultrasonic spray deposition method for the mass-production of high-performance nonenzymatic nanometer-thick film biosensors.
A lattice field theory for polymer systems with nearest-neighbor interaction energies (1987)

We generalize a lattice field theory that formally provides an exact description of the statistical mechanical entropy of nonoverlapping flexible polymers to enable treatment of nearest-neighbor interaction energies. The theory is explicitly solved within an extended mean field approximation for a system of polymer chains and voids, and we also provide mean field results for polymer–solvent–void and binary blend–void mixtures. In addition to recovering the Flory–Huggins mean field approximation for these systems, our extended definition of the mean field approximation contains a set of corrections to Flory–Huggins theory in the form of an expansion in powers of the nearest-neighbor interaction energies.
MISSED ANTERIOR CROSSING VESSELS DURING OPEN RETROPERITONEAL PYELOPLASTY: LAPAROSCOPIC TRANSPERITONEAL DISCOVERY AND REPAIR (2001)

Spiral CT angiography reliably delineates the renal vascular anatomy in patients with ureteropelvic junction obstruction. This study may be valuable before planned open retroperitoneal ureteropelvic junction obstruction repair. Laparoscopic pyeloplasty may successfully manage anterior crossing vessels associated with secondary ureteropelvic junction obstruction.
Detecting Route Attraction Attacks in Wireless Networks (2011)

Selecting high performance routes in wireless networks requires the exchange of link quality information among nodes. Adversaries can manipulate this functionality by advertising fake qualities for links; by doing so, they can attract routes and subsequently launch pernicious attacks. Our measurements suggest that malicious route attraction can fatally impact throughput. We design a framework that is effective against both independent and colluding attackers. In the latter case, we consider both local and remote colluders. With local collusion, malicious nodes exchange and advertise fake routing information to increase the probability of being selected as relays. Remote collusion refers to nodes residing in distant parts of the network that (i) create sybil identities in a local neighborhood and / or (ii) utilize link quality reports to advertise fake links. Our framework combines packet signing and frequency hopping to accurately detect the adversaries. We implement the framework on our testbed and conduct experiments to assess its efficacy. We observe that our framework provides significant throughput benefits by detecting attackers with 90% accuracy.

The Role of Polyvinylpyrrolidone in Hydrothermally Synthesized Ag/ZnO Nanocomposites and Their Photocatalytic Activities (2015)

Here we present a simple hydrothermal route for the preparation of photoactive ZnO and Ag/ZnO nanoparticles (NPs) synthesized in the presence and absence of polyvinylpyrrolidone (PVP). The low temperature synthesis is carried out in ethylene glycol (EG) medium at 180 degrees C, where EG is used as a reducing agent for the Ag+ ions. PVP is exploited as a size confining matrix for the Ag NPs. The present synthetic protocol allows the preparation of ZnO nanorods (NRs) with typical lengths of -200 nm and Ag/ZnO NPs with typical sizes of -100 nm. The photocatalytic activity of the as-prepared nanomaterials was tested for degradation of model pollutant methyl orange (MO) dye and terephthalic acid (TPA). We found that the Ag/ZnO NPs synthesized in PVP showed higher photoactivity than the commercial TiO2 (P25) powder or ZnO and Ag/ZnO NPs synthesized without PVP.
