The modification of jet shapes in Pb-Pb collisions, relative to those in pp collisions, is studied for jets associated with an isolated photon. The data were collected with the CMS detector at the LHC at a nucleon-nucleon center-of-mass energy of 5.02 TeV. Jet shapes are constructed from charged particles with track transverse momenta (p_{T}) above 1 GeV/c in annuli around the axes of jets with p_{T}^{jet}>30 GeV/c associated with an isolated photon with p_{T}^{γ}>60 GeV/c. The jet shape distributions are consistent between peripheral Pb-Pb and pp collisions, but are modified for more central Pb-Pb collisions. In these central Pb-Pb events, a larger fraction of the jet momentum is observed at larger distances from the jet axis compared to pp, reflecting the interaction between the partonic medium created in heavy ion collisions and the traversing partons.

The "bullet-horn" concept is applied to an application that requires a feed covering a 3.5 GHz to 12.3 GHz bandwidth.
Purification and Characterization of Purine Nucleoside Phosphorylase and Pyrimidine Nucleoside Phosphorylase from<i>Bacillus stearothermophilus</i>TH 6-2 (1996)

The purine nucleoside phosphorylase (Pu-NPase) and the pyrimidine nucleoside phosphorylase (Py-NPase) have been purified from Bacillus stearothermophilus TH 6-2. The Pu-NPase is a trimer of 30-kDa subunits and the Py-NPase is a dimer of 46-kDa subunits. The isoelectric points of Pu-NPase and Py-NPase were pH 4.3 and 4.6, respectively. The Pu-NPase could catalyze the phosphorolysis of inosine and guanosine, but not adenosine. the Py-NPase could phosphorolyze both uridine and thymidine.
Boosting the Transesterification Reaction by Adding a Single Na Atom into g-C3N4 Catalyst for Biodiesel Production: A First-Principles Study (2022)

Increasing environmental problems and the energy crisis have led to interest in the development of alternative energy. One of the most promising sustainable alternatives to fossil fuel is biodiesel which is typically produced from the transesterification of refined vegetable oils using a homogeneous base catalyst. However, the current process limitations and steep production costs associated with the use of homogeneous catalysts have limited the global-wide acceptance of biodiesel. Heterogeneous catalysts have been considered suitable alternatives, but they still suffer from low catalytic activity. In this study, by using density functional theory (DFT) calculations, we examined the electronic and catalytic activity of the single Na-doped graphitic carbon nitrides (indicated by Na-doped g-C3N4) toward the efficient biodiesel (acetic acid methyl ester) production via the transesterification of triglyceride (triacetin). Our DFT calculation on reaction energetics and barriers revealed the enhancement of biodiesel productivity in the Na-doped catalyst compared to the pristine g-C3N4 catalyst. This was related to the large reduction of the barrier in the rate-limiting step. In addition, we investigated the acidity/basicity and electron distribution and density of state for the Na-doped and pristine g-C3N4 catalysts to better understand the role of the Na atom in determining the transesterification reaction. This study highlights the importance of the dopant in a g-C3N4 catalyst in determining the transesterification reaction, which may open new routes to improve biodiesel production.
Effects of prolactin on ventricular myocyte shortening and calcium transport in the streptozotocin-induced diabetic rat (2020)

The physiological role of prolactin (PRL) in the heart, and in particular the diabetic heart, are largely unknown. The effects of PRL on ventricular myocyte shortening and Ca<sup>2+</sup> transport in the streptozotocin (STZ) - induced diabetic and in age-matched control rats were investigated. PRL receptor protein, myocyte shortening, intracellular [Ca<sup>2+</sup>], L-type Ca<sup>2+</sup> current were measured by Western blot, cell imaging, fluorescence photometry and whole-cell patch-clamp techniques, respectively. Compared to normal Tyrode solution (NT), PRL (50 ng/ml) significantly (p < 0.05) increased the amplitude of shortening in myocytes from control (7.43 ± 0.38 vs. 9.68 ± 0.46 %) and diabetic (6.57 ± 0.24 vs. 8.91 ± 0.44 %) heart (n = 44-49 cells). Compared to NT, PRL (50 ng/ml) significantly increased the amplitude of Ca<sup>2+</sup> transients in myocytes from control (0.084 ± 0.004 vs. 0.115 ± 0.007 Fura-2 ratio units) and diabetic (0.087 ± 0.007 vs. 0.112 ± 0.006 Fura-2 ratio units) heart (n = 36-50 cells). PRL did not significantly alter the amplitude of caffeine-evoked Ca<sup>2+</sup> transients however, PRL significantly increased the fractional release of Ca<sup>2+</sup> in myocytes from control (21 %) and diabetic (14 %) and heart. The rate of Ca<sup>2+</sup> transient recovery following PRL treatment was significantly increased in myocytes from diabetic and control heart. Amplitude of L-type Ca<sup>2+</sup> current was not significantly altered by diabetes or by PRL. PRL increased the amplitude of shortening and Ca<sup>2+</sup> transients in myocytes from control and diabetic heart. Increased fractional release of sarcoplasmic reticulum Ca<sup>2+</sup> may partly underlie the positive inotropic effects of PRL in ventricular myocytes from control and STZ-induced diabetic rat.
A study on packaging design of SiC power module using near-field magnetic scanning techniques (2017)

This report focuses the current distribution in a module identified with magnetic near-field intensity for optimizing layout and packaging design of silicon carbide (SiC) power module. This measurement methodology can visualize the practical current distribution on a wiring pattern in a module and can estimate the effect of snubber capacitor in a DC-link of half-bridge to suppress the voltage overshoot and ringing oscillation.
Preparation of TiO&lt;sub&gt;2&lt;/sub&gt; Thin Films by Electrophoresis Deposition Method for Dye-Sensitized Solar Cells (2007)

The purpose of this study is to prepare high-quality TiO2 thin films for dye-sensitized solar cells using the electrophoresis method. A high-quality TiO2 thin film has a thickness of approximately 10 μm and no crack on the surface. In this study, TiO2 thin films were deposited by changing the configuration of electrophoresis electrodes. When electrodes were set parallel to horizontal and ITO glass substrate was set in the upper electrode, an excellent TiO2 thin film of approximately 10 μm thickness was obtained by depositing very thin TiO2 films as a buffer layer. The new film has the highest open-circuit voltage and short-circuit current density.
An Analytical Model for the Optimisation of Metal Foam for Power Electronics Cooling (2019)

With regular technological breakthroughs in power electronics, there is an ever-increasing need for efficient thermal management. This has led to an increased focus on the study of metal foam enhanced heat sinks. The aim of this paper is to develop and validate an analytical model to calculate the total thermal resistance of a metal foam filled channel. The model will then be used to optimise the microstructure of the foam in order to minimise the thermal resistance of the channel. Foams with three different porosities (40, 60 and 80%) were compared with numerical simulations and the deviation in results was found to be less than 2%. When optimised under a fixed pressure loss of 100kPa, a thermal resistance of 0.023K/W was found.
Clinical realization of short-lag spatial coherence imaging on 2D arrays (2012)

To improve image quality in 3D ultrasound we extended a coherence-based imaging method named Short-lag Spatial Coherence (SLSC) imaging to 2D arrays. Specifically, we collected partially beamformed channel signals from a clinical matrix array and 3D ultrasound scanner to reconstruct matched SLSC and B-mode volumes of the in vivo liver vasculature. Volumetric SLSC imaging shows suppressed clutter and improved visualization of blood vessels when compared to conventional 3D B-mode. Contrast and CNR values computed on the selected cross-sections from the matched volumes range from 14 dB to 18 dB and from 1.40 to 2.10 for SLSC and from 4 dB to 13 dB and from 0.63 to 1.05 for B-mode slices.
Tagmark (2008)

Radio Frequency Identification (RFID) promises optimization of commodity flows in all industry segments. But due to physical constraints, RFID technology cannot detect all RFID tags from an assembly of items. This poses problems when integrating RFID data with enterprise-backend systems for tasks like inventory management or shelf replenishment. In this paper we propose the TagMark method to accomplish this integration. TagMark targets at a retailer scenario, where it estimates the number of tagged items from samples like the sales history or the tags read by smart shelves. The problem is challenging because most existing estimation methods depend on assumptions that do not hold in typical RFID applications, e.g., static item sets, simple random samples, or the availability of samples with user-defined sizes. TagMark adapts mark-recapture-methods in order to provide guarantees for the accuracy of the estimation and bounds for the sample sizes. It can be implemented as a database extension, allowing seamless integration into existing enterprise backend systems. A study with RFID-equipped goods acknowledges that our approach is effective in realistic scenarios, and database experiments with up to 1,000,000 items confirm that it can be efficiently implemented. Finally, we explore a broad range of extreme conditions that might stress TagMark, including a thief who knows the location of unread items.
Importance of the Order of Addition of the Alumina Precursor and its Type Into Al-SBA-15 Mesoporous Materials for Use as Water Adsorbents (2018)

In the present report, Al-SBA mesoporous materials were investigated for use as water adsorbents. Different precursors for aluminum were investigated: aluminum sulfate and nitrate, boehmite, and aluminum tri-sec-butoxide. Furthermore, three different procedures for addition of the silica and alumina sources were tested. Samples were characterized by nitrogen adsorption to observe their textural characteristics and by thermogravimetric desorption of water to address their performance. The sample synthesized with aluminum tri-sec-butoxide as aluminum precursor and a pre-hydrolysis step of the silica source presented the highest adsorption capacity: 1057 g.kg-1. It was also observed that water attaches more strongly to Al-containing samples than to pure silica, and that water adsorption capacity is more related to the pore volume of samples than to their surface area. This work has shown that functionalizing SBA-15 materials with aluminum is a promising strategy for producing water adsorbents with improved performance and potential for many applications.
Extraction Recovery (2017)

Approaches for analytical-scale extraction are developing rapidly as new strategies are implemented to improve sample throughput, to minimize material use in laboratory methods, and to develop on-site capabilities. In this contribution, definitions and recommendations for symbols for the terms used in analytical extraction are presented. Exhaustive, microextraction, elevated temperature, microwave- and ultrasound-assisted, parallel batch, flow through systems, and membrane extraction approaches are discussed. An associated tutorial titled “Extraction” provides a detailed introduction to the topic.
Salacia oblonga extract reduces postprandial glycemia following a solid, high-starch meal. (2007)

We developed and validated a nomogram to predict lymph node metastasis in gastric cancer before surgery. This nomogram can be broadly applied, even in general hospitals, and is useful for decisions regarding treatment programs for patients.
Semi-automatic catheter model generation using biplane x-ray images (2013)

Recently, techniques for the automatic detection or tracking of surgical instruments in X-ray guided computer-assisted interventions have emerged. The purposes of these methods are to facilitate inter-modality registration, motion compensation, enhanced visualization or automatic landmark generation in augmented-reality applications. Most techniques incorporate a model of the device as prior information to evaluate results obtained from a low-level detector. In this paper, we present novel approaches which are able to generate both 2-D and 3-D models of circular and linear catheters from biplane X-ray images with only minimal user input. We apply these methods in the context of Electrophysiology to generate models of ablation and mapping catheters. An evaluation on clinical data sets yielded promising results.
Synaptic neurexin-1 assembles into dynamically regulated active zone nanoclusters (2019)

Neurexins are well-characterized presynaptic cell adhesion molecules that engage multifarious postsynaptic ligands and organize diverse synapse properties. However, the precise synaptic localization of neurexins remains enigmatic. Using super-resolution microscopy, we demonstrate that neurexin-1 forms discrete nanoclusters at excitatory synapses, revealing a novel organizational feature of synaptic architecture. Synapses generally contain a single nanocluster that comprises more than four neurexin-1 molecules and that also includes neurexin-2 and/or neurexin-3 isoforms. Moreover, we find that neurexin-1 is physiologically cleaved by ADAM10 similar to its ligand neuroligin-1, with ∼4-6% of neurexin-1 and ∼2-3% of neuroligin-1 present in the adult brain as soluble ectodomain proteins. Blocking ADAM10-mediated neurexin-1 cleavage dramatically increased the synaptic neurexin-1 content, thereby elevating the percentage of Homer1(+) excitatory synapses containing neurexin-1 nanoclusters from 40-50% to ∼80%, and doubling the number of neurexin-1 molecules per nanocluster. Taken together, our results reveal an unexpected nanodomain organization of synapses in which neurexin-1 is assembled into discrete presynaptic nanoclusters that are dynamically regulated via ectodomain cleavage.
Speeding up Consensus by Chasing Fast Decisions (2017)

This paper proposes Caesar, a novel multi-leader Generalized Consensus protocol for geographically replicated sites. The main goal of Caesar is to overcome one of the major limitations of existing approaches, which is the significant performance degradation when application workload produces conflicting requests. Caesar does that by changing the way a fast decision is taken: its ordering protocol does not reject a fast decision for a client request if a quorum of nodes reply with different dependency sets for that request. The effectiveness of Caesar is demonstrated through an evaluation study performed on Amazon's EC2 infrastructure using 5 geo-replicated sites. Caesar outperforms other multi-leader (e.g., EPaxos) competitors by as much as 1.7x in the presence of 30% conflicting requests, and single-leader (e.g., Multi-Paxos) by up to 3.5x.
New Layered Tin(II) Thiophosphates ASnPS<sub>4</sub> (A = K, Rb, Cs): Synthesis, Structure, Glass Formation, and the Modulated CsSnPS<sub>4</sub> (2012)

The layered compounds KSnPS(4) (1), RbSnPS(4) (2), and CsSnPS(4) (3) were synthesized using the chalcophosphate flux technique at high temperature and are rare examples of divalent Sn(II) thiophosphates. Orange polyhedral crystals of compound 1 crystallize in the monoclinic space group P2(1)/c with a = 6.6673(13) Å, b = 11.9697(24) Å, c = 8.7604(18), and β=127.347(8)° in a 2-dimensional layered structure. Compound 2 is isostructural to 1. Yellow block shaped crystals of compound 3 crystallize in the monoclinic superspace group P2(1)(αβ0)0 with a commensurate q-vector at 1/4a* + 1/4c* with a = 18.0477(14) Å, b = 6.2021(5) Å, and c = 6.8415(5) Å. The structure of all three compounds contains SnS(3) pyramids, which is an extremely rare solid state chalcogenide coordination environment. All three compounds are semiconductors having well-defined band-gaps between 2.0 and 2.2 eV. The compounds are congruently melting and can be obtained as glasses by rapid quenching of the melt, which subsequently crystallize upon heating.
Single-mode fiber-optic demultiplexer (1987)

A study was made of the properties of fused single-mode biconical couplers fabricated in a high-frequency electric discharge. A multiplexer–demultiplexer was constructed for the first time with an interval of 1.5 nm between the channels, channel isolation of 20 dB, and excess losses of 0.2 dB. Continuous adjustment of the characteristics of this fused demultiplexer was possible.
Scalable Directory Services Using Proactivity (2002)

Common to computational grids and pervasive computing is the need for an expressive, efficient, and scalable directory service that provides information about objects in the environment. We argue that a directory interface that ‘pushes’ information to clients about changes to objects can significantly improve scalability. This paper describes the design, implementation, and evaluation of the Proactive Directory Service (PDS). PDS’ interface supports a customizable ‘proactive’ mode through which clients can subscribe to be notified about changes to their objects of interest. Clients can dynamically tune the detail and granularity of these notifications through filter functions instantiated at the server or at the object’s owner, and by remotely tuning the functionality of those filters. We compare PDS’ performance against off-the-shelf implementations of DNS and the Lightweight Directory Access Protocol. Our evaluation results confirm the expected performance advantages of this approach and demonstrate that customized notification through filter functions can reduce bandwidth utilization while improving the performance of both clients and directory servers.
Metamizole: An underrated agent causing severe idiosyncratic drug‐induced liver injury (2020)

Elevation of liver enzymes or acute liver failure are not mentioned in the German drug label of metamizole as potential side effects. Our study reveals that in Germany and Europe, metamizole is a frequent and underrated agent causing DILI.
Optical Doppler coherence tomography algorithms: quantitative analysis (2003)

We present, to our knowledge, the first quantitative comparisons of five flow estimation algorithms for optical Doppler coherent tomography. We have used simulated 1D, 2D, and in vivo blood flow data to investigate the estimation accuracy and sensitivity of these algorithms. We introduce, among these five methods, 3 new algorithms: weighted centroid, sliding-window filtering, and autocorrelation. The weighted centroid, sliding-window filtering and the existing adaptive centroid algorithms have considerably higher sensitivity and accuracy over the autocorrelation and existing cross-correlation methods.
Bioactive Lactose-Modified Chitosan Acts as a Temporary Extracellular Matrix for the Formation of Chondro-Aggregates (2022)

Spheroids based on chondrocytes are gaining interest in the treatment of injured cartilage tissue due to their regenerative potential. In this study, chondrocyte-based aggregates were formed by culturing cells on a polymeric coating of a lactose-modified chitosan (CTL) and their evolution was followed for 14 days of culture. Morphological analyses through scanning electron microscopy indicated that these cell aggregates formed by a process of cell aggregation rather than proliferation, resulting in structures with an irregular morphology that were up to 1 mm in size. Chondrocytes interact very closely with CTL. In the early days of cellular aggregation, CTL is distributed among the cells, while in later stages, it is localized in the inner part of the aggregates, forming an amorphous matrix. The initial outer position of the polymer is replaced over time by an increased matrix deposition whose main component is type II collagen. Transmission electron microscopy pointed out that the chondrocytes internalized the polymer during the first days of culture. The presence of CTL does not affect the ability of cells to migrate from chondro-aggregates when transferred to uncoated wells, mimicking the ability of cells to colonize a cartilage defect. Overall, these results suggest that CTL plays a role as a temporary matrix for chondrocytes aggregation during chondro-aggregates formation. This opens up innovative therapeutic approaches for cartilage regeneration without the need to use a scaffold to deliver cells to the damaged site.KEYWORDS: chondrocytes, spheroids, lactose-modified chitosan, cartilage regeneration, bioactive polysaccharide
6TiSCH Resource Management and Interaction using CoAP (2015)

The [IEEE802154e] standardizes the TSCH mode of operation and defines
the mechanisms for layer 2 communication between conforming devices.
6top defines a set of commands to monitor and manage the TSCH
schedule. To realize the full functionality of sensor networks and
allow their adoption and use in real applications we need additional
mechanisms. Specifically, the interaction with 6top, control and
modify schedules, monitor parameters etc must be defined. Higher
layers monitoring and management entities are then able to use these
capabilities to create feedback loops. Although, there have been many
custom implementations of such feedback loops between the routing,
transport and MAC layers in sensor network deployments, there has been
a lack of standards based approaches. This draft defines the messaging
between monitoring and management entities and the 6top layer and a
mapping to the 6top commands. The document also presents a particular
implementation of the generic data model specified in [I-D.ietf-
6tisch-6top-interface] based on CoAP and CBOR.
Single optical mode-spontaneous emission coupling of a quantum dot in a three-dimensional microcavity (2003)

By investigating the interaction of single atoms with a cavity, pioneering experiments in the 1980's demonstrated that the spontaneous emission from an atom is intimately tied to the electromagnetic vacuum field distribution. By adjusting the field distribution with a cavity a discrete mode distribution was created, and enhanced and inhibited spontaneous emission from the atom was observed. We have demonstrated a semiconductor analog of the single-atom cavity experiments using a single InAs quantum dot (QD) as an artificial atom. With this solid-state implementation it is possible to make compact, regulated single-photon sources with high efficiency and high repetition rate for applications such as quantum cryptography.
