DRYING OF GELATINIZED WHOLE WHEAT (2001)

Whole grains of gelatinized durum and soft wheat were dried by forced and natural convection at 40, 60, 80, and 100°C. Magnetic resonance images taken periodically during drying indicated that Fick's diffusion is not applicable to describe the moisture transfer during drying of the gelatinized wheat grains. A simple mathematical model based on overall moisture balance fitted the experimental data very well. The drying took place in the falling rate period, which was approximated by two regions – first and second falling rate periods (FFRP and SFRP). The internal drying coefficient linearly increased with increasing drying temperature, and was almost an order of magnitude (from 104 to 105 s-1) higher during FFRP than SFRP. The soft wheat dried faster than the durum wheat. The effect of forced convection was more pronounced during FFRP than SFRP.
Healing of a Topological Scar: Coordination Defects in a Honeycomb Lattice (2023)

A crystal structure with a point defect typically returns to its ideal local structure upon moving a few bond lengths away from the defect; topological defects such as dislocations or disclinations also heal rapidly in this regard. Here we describe a simple point defect -- a two-fold atom incorporated at the growth edge of a 2D hexagonal honeycomb material -- whose healing may require a defect complex with 50 or more atoms. $\textit{Topologically}$ the two-fold atom disappears into a single 'long bond' between its neighbors, thereby inducing a pentagonal disclination. However, $\textit{chemically}$ this disclination occupies as much physical space as a six-fold ring. This incompatibility of chemistry and topology can cause a ''ringing'' of the Gaussian curvature that creates an expansive healing region and may even spawn a semi-infinite grain boundary propagating outwards from the topological scar.
Vertical-cavity surface-emitting lasers with integratedrefractive microlenses (1995)

The fabrication and performance of a vertical cavity surface emitting laser array integrated with microlenses are reported. The lasers emit at 967 nm through the substrate with integral polyimide microlenses. This design reduces beam divergence and provides an integrated device that emits a nearly collimated beam for applications such as optical interconnects.
3D Segmentation of the Prostate via Poisson Inverse Gradient Initialization (2007)

Accurate segmentation and volumetric assessment of the enlarged prostate is critical to assessment of cancer progression. Moreover, 3D segmentation is necessary for treatment in both radiotherapy and brachytherapy. We propose a 3D segmentation solution for ultrasound images of the prostate based on deformable surfaces. The deformable surfaces are propelled by the vector field convolution (VFC) external force model. This external force has both computational efficiency and solution quality advantages over existing techniques such as gradient vector flow (GVF). A salient aspect of the segmentation solution proposed here is the ability to automatically initialize the deformable surface in 3D. The initialization method exploits a novel Poisson inverse gradient technique that essentially solves the inverse problem from the external force field to the external energy and determines the most likely coarse segmentation. We validate our 3D segmentation on simulated images of the prostate. Furthermore, simulated data show that PIG initialization leads to a 60% reduction in segmentation error for high curvature contours.
The Effect of Vasopressin on Ciliary Blood Flow and Aqueous Flow (2013)

The results indicate that AVP can modulate IOP by different dose-dependent physiological mechanisms. The shifts of the CilBF-AqF relationship suggest that the reduction of AqF by the low AVP infusion rate is mainly provoked by inhibiting secretory processes in the ciliary epithelium. In contrast, at the high AVP infusion rate, the AqF reduction is caused by either reduced CilBF or more likely by a combined effect of reduced CilBF and secretory inhibition.
VisDB (1995)

The VisDB system developed at the University of Munich is a sophisticated tool for visualizing and analyzing large databases. The key idea of the VisDB system is to support the exploration of large databases by using the phenomenal abilities of the human vision system which is able to analyze visualizations of mid-size to large amounts of data very efficiently. The goal of the VisDB system is to provide visualizations of large portions of the database, allowing properties of the data and structure in the data to become perceptually apparent.
Tolerability of gefitinib in patients receiving treatment in everyday clinical practice (2003)

Gefitinib ("Iressa", ZD1839), an epidermal growth factor receptor tyrosine kinase inhibitor, has recently been approved in several countries for use in advanced or metastatic non-small-cell lung cancer (NSCLC). In contrast to chemotherapies, which are generally used at or near their maximum-tolerated dose (MTD), gefitinib is used at an optimal biological dose (250 mg day(-1)), which is substantially below its MTD, minimising the risk of adverse events without compromising efficacy. Tolerability data from the compassionate use of gefitinib in the "Iressa" Expanded Access Programme support the favourable safety profile of the agent reported in Phase I and II trials. In both settings, the majority of adverse drug reactions were mild/moderate and consisted mainly of grade 1/2 diarrhoea and skin rash. Although skin rash has been suggested to predict response to gefitinib, available data do not support this hypothesis. Overall, these tolerability data demonstrate that gefitinib has a relatively benign side-effect profile and is a well-tolerated treatment option for patients with previously treated NCSLC, who currently have few alternatives.
One Step Synthesis of the Smallest Photoluminescent and Paramagnetic PVP-Protected Gold Atomic Clusters (2010)

Gold atomic clusters of only two and three atoms were prepared by a simple electrochemical technique based on the anodic dissolution of a gold electrode in the presence of PVP, and subsequent electroreduction of the Au-PVP complexes. These clusters show stable photoluminescent and magnetic properties, which make them the smallest and most elemental gold (0) building blocks in nature (after atoms) bringing new possibilities to construct novel nano/microstructures with large potential interest in biomedicine, catalysis, and so forth.

Microwave-assisted ultrafast synthesis of adjustable bimetal phosphide/graphene heterostructures from MOFs for efficient electrochemical water splitting (2019)

An ultrafast microwave-assisted thermal conversion route is employed to tune the heterostructure of FeNiP/graphene composites for OER and HER activity enhancement.
Synthesis of Microporous Aluminosilicate by Direct Thermal Activation of Phenyl-Substituted Single-Source Aluminosilicate Molecular Precursors (2022)

The construction of aluminosilicates from versatile molecular precursors (MPs) represents a promising alternative strategy to conventional processes based on monomeric molecular or polymeric Al and Si sources. However, the use of MPs often suffers from drawbacks such as the decomposition of the core structures in the presence of solvents, acids, or bases. In this work, we demonstrate a simple thermal synthesis of porous aluminosilicates from single-source spiro-7-type MPs that consist of a tetrahedral Al atom and six Si atoms functionalized with 12 phenyl (Ph) groups, (C<sup>+</sup>)[Al{Ph<sub>2</sub>Si(OSiPh<sub>2</sub>O)<sub>2</sub>}<sub>2</sub>]<sup>-</sup> (<b>C<sup>+</sup>[AlSi<sub>6</sub>]<sup>-</sup></b>; C<sup>+</sup> = pyridinium cation (PyH<sup>+</sup>), Na<sup>+</sup>, K<sup>+</sup>, Rb<sup>+</sup>, or Cs<sup>+</sup>), without using a solvent or activator. Microporous aluminosilicates synthesized <i>via</i> the thermal treatment of <b>C<sup>+</sup>[AlSi<sub>6</sub>]<sup>-</sup></b> under a 79% N<sub>2</sub> + 21% O<sub>2</sub> atmosphere exhibited extremely low carbon contents (0.10-1.28%), together with Si/Al ratios of 3.9-6.7 ± 0.2 and surface areas of 103.1-246.3 m<sup>2</sup>/g. The solid-state <sup>27</sup>Al and <sup>29</sup>Si MAS NMR spectra suggest that the obtained aluminosilicates with alkali cations retain a tetrahedral Al site derived from the spiro-7-type core structure. After a proton-exchange reaction, the aluminosilicates showed almost 1.5 times higher reactivity in the catalytic ring-opening of styrene oxide than the aluminosilicate before proton exchange due to the catalytically active OH site being predominantly bridged by tetrahedral Al and Si atoms. These results suggest that the present MP strategy is a promising method for the introduction of key structures into active inorganic materials.
Iodine Deficiency in Latvia: Current Status and Need for National Recommendations (2017)

Abstract In the absence of a mandatory salt iodisation programme, two nationwide cross-sectional cluster surveys revealed persisting iodine deficiency among Latvian schoolchildren during the spring season and a noteworthy iodine deficiency in pregnant women in Latvia; these deficiencies warrant intervention. The consequences of mild-to-moderate iodine deficiency during pregnancy and lactation can adversely affect foetal brain development. Data from a Latvian population survey revealed the consumption of approximately 100 μg of iodine per day through foods and iodised salt. Therefore, strategies to increase the consumption of iodine-containing products should be implemented, particularly for children. In addition, to meet the increased iodine requirement during pregnancy, pregnant women should take daily supplements containing 150 μg iodine from the earliest time possible. All women of childbearing age should be advised to increase their dietary iodine intake by using iodised table salt and iodine-rich products: seafood, milk and milk products. For women with pre-existing thyroid pathologies, the medical decision should be considered on a case-by-case basis. Urinary iodine concentration monitoring among schoolchildren and pregnant women and neonatal thyrotropin registry analysis every five years would be an appropriate strategy for maintaining iodine intake within the interval that prevents iodine deficiency disorders.
Adaptive Decision Fusion based cooperative spectrum sensing for Cognitive Radio systems (2011)

In this paper, an online Adaptive Decision Fusion (ADF) framework is proposed for the central spectrum awareness engine of a spectrum sensor network in Cognitive Radio (CR) systems. Online learning approaches are powerful tools for problems where drifts in concepts take place. Cooperative spectrum sensing in cognitive radio networks is such a problem where channel characteristics and utilization patterns change frequently. The importance of this problem stems from the requirement that secondary users must adjust their frequency utilization strategies in such a way that the communication performance of the primary users would not be degraded by any means. In the proposed framework, sensing values from several sensor nodes are fused together by weighted linear combination at the central spectrum awareness engine. The weights are updated on-line according to an active fusion method based on performing orthogonal projections onto convex sets describing power reading values from each sensor. The proposed adaptive fusion strategy for cooperative spectrum sensing can operate independent from the channel type between the primary user and secondary users. Results of simulations and experiments for the proposed method conducted in laboratory are also presented.

Corticosteroid Therapy During Acute Bronchiolitis in Patients Who Later Develop Asthma (2017)

Corticosteroids were not associated with improved outcome in patients with bronchiolitis who were later hospitalized with asthma. Moderately ill patients with no comorbidities may warrant further study.
RX871024 Induces Ca2+ Mobilization From Thapsigargin-Sensitive Stores in Mouse Pancreatic β-Cells (1998)

The effects of RX871024, a compound with an imidazoline structure, on cytoplasmic-free Ca2+ concentration ([Ca2+]i) in mouse pancreatic beta-cells were studied. RX871024 modulates [Ca2+]i by at least two mechanisms. One mechanism involves closure of ATP-regulated K+ channels, resulting in membrane depolarization, opening of voltage-gated L-type Ca2+ channels, and a subsequent increase in [Ca2+]i. Another mechanism, reported here for the first time, deals with RX871024-induced mobilization of Ca2+ from nonmitochondrial thapsigargin-sensitive intracellular stores. Reduced glutathione, inhibitors of cytochrome P-450, and monoaminooxidases A and B blocked this Ca2+ mobilization. It is concluded that the mechanism of RX871024-induced Ca2+ mobilization from intracellular stores involves changes in the oxidation/reduction state of the pancreatic beta-cell and may be controlled by cytochrome P-450.
Permeation of Chlorhexidine from Alcoholic and Aqueous Solutions within Excised Human Skin (2009)

Chlorhexidine digluconate (CHG) is widely used in the clinical setting for skin antisepsis prior to incision or insertion of medical devices, e.g., central venous catheters (11-13); however, its permeation into skin is limited (6, 7, 9, 10, 16). In a recent study, we demonstrated the limited penetration of CHG in a skin model comprising full-thickness excised human skin following the application of 2% (wt/vol) aqueous CHG (9). The aim of this current study was to compare the penetration of chlorhexidine into skin following the topical application of 2% (wt/vol) CHG in 70% (vol/vol) isopropyl alcohol (IPA) with that of aqueous CHG.
Hydrogenation of carbon dioxide: a comparison of different types of active catalysts (2014)

Comparison of the activity and CO selectivity of four principally different types of catalysts in CO2 hydrogenation, namely, LaNi5, Rh/ZnO–CuO, fumed Fe2O3–K2O–Al2O3 and Au/SO4–ZrO2, in the entire temperature range at an atmospheric pressure was performed. The use of the intermetallide LaNi5 catalyst provides an enhanced activity in CO2 hydrogenation with prevailing methane formation, while other catalysts demonstrated predominant formation of CO.

Thymus-dependent lymphocytes in human bone marrow. (1975)

Human bone marrow is known to contain significant numbers of bursa-dependent lymphocytes. The presence of thymus-dependent (T) cells is controversial. Bone marrow cells obtained from healthy volunteers was fractionated by density centrifugation. A lymphocte-enriched subpopulation was shown to be reactive to alloantigens in mixed lymphocyte culture and to contain substantial numbers of T lymphocytes. The T lymphocytes were detected by cell surface markers (rosette formation with sheep RBC) and by response to the mitogens phytohemagglutinin and concanavalin A. Bone marrow T cells exhibited functional characteristics quantitatively different from peripheral blood T cells, suggesting that they may represent a particular subpopulation of T cells. The lymphocyte-enriched fraction additionally contained committed granulopoietic stem cells capable of colony formation in semisolid gel. The presence of T cells in human bone marrow is consistent with findings in other mammals and may explain the high incidence of graft versus host disease in bone marrow transplant recipients.
Evaluating PICA Capability for Future Low Voltage SOI Chips (2008)

Abstract In this paper we evaluate the possibility of extending Time Resolved Emission (TRE) technology towards future low voltage SOI technologies. In particular, we investigate and quantify the gain offered by the InGaAs detector improvements devised by Credence Corp., now DCG Systems, the manufacturer of the Emiscope III PICA system used in this analysis. Experiments on a test chip fabricated in the IBM SOI 65 nm technology will demonstrate that the improved tool guarantees the same Signal-to-Noise Ratio (SNR) even at ~90 mV lower supply voltages. In the second part of the paper we also discuss various other acquisition optimizations of the system. Although the analysis presented here refers to a specific tool, the large majority of the results and discussions can easily be generalized and applied to other PICA systems and detectors, as well as low voltage bulk silicon technologies.
Investigation of Prediction Accuracy, Sensitivity, and Parameter Stability of Large-Scale Propagation Path Loss Models for 5G Wireless Communications (2016)

This paper compares three candidate large-scale propagation path loss models for use over the entire microwave and millimeter-wave (mmWave) radio spectrum: the alpha–beta–gamma (ABG) model, the close-in (CI) free-space reference distance model, and the CI model with a frequency-weighted path loss exponent (CIF). Each of these models has been recently studied for use in standards bodies such as 3rd Generation Partnership Project (3GPP) and for use in the design of fifth generation wireless systems in urban macrocell, urban microcell, and indoor office and shopping mall scenarios. Here, we compare the accuracy and sensitivity of these models using measured data from 30 propagation measurement data sets from 2 to 73 GHz over distances ranging from 4 to 1238 m. A series of sensitivity analyses of the three models shows that the physically based two-parameter CI model and three-parameter CIF model offer computational simplicity, have very similar goodness of fit (i.e., the shadow fading standard deviation), exhibit more stable model parameter behavior across frequencies and distances, and yield smaller prediction error in sensitivity tests across distances and frequencies, when compared to the four-parameter ABG model. Results show the CI model with a 1-m reference distance is suitable for outdoor environments, while the CIF model is more appropriate for indoor modeling. The CI and CIF models are easily implemented in existing 3GPP models by making a very subtle modification.
Magnetotransport Properties of Quasi-Free-Standing Epitaxial Graphene Bilayer on SiC: Evidence for Bernal Stacking (2011)

We investigate the magnetotransport properties of quasi-free-standing epitaxial graphene bilayer on SiC, grown by atmospheric pressure graphitization in Ar, followed by H(2) intercalation. At the charge neutrality point, the longitudinal resistance shows an insulating behavior, which follows a temperature dependence consistent with variable range hopping transport in a gapped state. In a perpendicular magnetic field, we observe quantum Hall states (QHSs) both at filling factors (ν) multiples of four (ν = 4, 8, 12), as well as broken valley symmetry QHSs at ν = 0 and ν = 6. These results unambiguously show that the quasi-free-standing graphene bilayer grown on the Si-face of SiC exhibits Bernal stacking.
