Agricultural Soil Spectral Response and Properties Assessment: Effects of Measurement Protocol and Data Mining Technique (2017)

Soil spectroscopy has shown to be a fast, cost-effective, environmentally friendly, non-destructive, reproducible and repeatable analytical technique. Soil components, as well as types of instruments, protocols, sampling methods, sample preparation, spectral acquisition techniques and analytical algorithms have a combined influence on the final performance. Therefore, it is important to characterize these differences and to introduce an effective approach in order to minimize the technical factors that alter reflectance spectra and consequent prediction. To quantify this alteration, a joint project between Czech University of Life Sciences Prague (CULS) and Tel-Aviv University (TAU) was conducted to estimate Cox, pH-H2O, pH-KCl and selected forms of Fe and Mn. Two different soil spectral measurement protocols and two data mining techniques were used to examine seventy-eight soil samples from five agricultural areas in different parts of the Czech Republic. Spectral measurements at both laboratories were made using different ASD spectroradiometers. The CULS protocol was based on employing a contact probe (CP) spectral measurement scheme, while the TAU protocol was carried out using a CP measurement method, accompanied with the internal soil standard (ISS) procedure. Two spectral datasets, acquired from different protocols, were both analyzed using partial least square regression (PLSR) technique as well as the PARACUDA II®, a new data mining engine for optimizing PLSR models. The results showed that spectra based on the CULS setup (non-ISS) demonstrated significantly higher albedo intensity and reflectance values relative to the TAU setup with ISS. However, the majority of statistics using the TAU protocol was not noticeably better than the CULS spectra. The paper also highlighted that under both measurement protocols, the PARACUDA II® engine proved to be a powerful tool for providing better results than PLSR. Such initiative is not only a way to unlock current limitations of soil spectroscopy, but also offers considerable efficiency and cost- and time-saving possibilities, which lead to further improvements in prediction performance of spectral models.
Pressure Gradients in the Trabecular Pore Space of Femurs During Physiologic Loading (2013)

Bone marrow is an important niche for mesenchymal stromal cells (MSCs), which are progenitors for connective tissue cells. MSCs respond to mechanical stimuli (1). For example, steady and oscillatory fluid flow both affect MSC differentiation to the osteogenic lineages (2), while hydrostatic pressure increases MSC osteogenic protein expression (3). Both pressure and fluid flow are induced in bone marrow during loading due to the poroelastic nature of trabecular bone, and these may affect the differentiation or proliferation of the resident stromal cells.

Enhanced Phase, Thermal and Aqueous Stability of the Embedded the CsPbI3 Ncs in Cs4PbI6 Ncs (2022)

Increasing the stability of lead halide perovskites (LHPs) is required for integrating them into light-emitting devices. To date, most studies toward this direction have primarily concentrated on improving the chemical stability of green-emitting LHPs. In this work, red-emitting CsPbI 3 –Cs 4 PbI 6 hybrid nanocrystals (NCs) were synthesized with a high photoluminescence (PL) quantum yield of ∼90%. Their hybrid structure was examined via structural (Rietveld) refinement analysis and transmission electron microscopy. Rietveld refinement also revealed that the black polymorph of CsPbI 3 NCs is an orthorhombic perovskite rather than a cubic one. The thermodynamic stability of the CsPbI 3 NCs in Cs 4 PbI 6 matrices is enhanced in both solutions and films for up to several weeks. The enhanced stability of the embedded CsPbI 3 NCs is attributed to the lowering of their Gibbs free energy, as determined on the basis of experimental data. Additionally, the hybrid NCs exhibit unprecedented emission stability—maintaining 65% of their original PL efficiency at 150 °C—and improved aqueous stability.
CEREBRAL DYSGENESIS (AGENESIS) (1939)

The term cerebral agenesis is frequently used by pediatricians and neurologists to denote a common entity characterized by mental defect plus developmental retardation associated with neurologic signs of varying degree. Congenital anomalies other than those of the central nervous system are also frequently associated with this condition. Cerebral agenesis represents a group of encephalopathies distinguishable in most instances from conditions produced by injury at birth; the lesions observed in cases of agenesis probably may be attributed to maldevelopment of the central nervous system in utero. In Alpers and Marcovitz'<sup>1</sup>excellent discussion of the subject, the pathologic evidence for intrauterine maldevelopment is reviewed to date. Cerebral agenesis is, strictly speaking, a misnomer, since agenesis presupposes lack of development or nondevelopment of an organ or of part of an organ (as, for example, in the designation agenesis of the corpus callosum). Abnormal development of the cortex or of other parts of
Modelling of complex RF/wireless structures using computationally optimized time-domain techniques: Research Articles (2004)

The modelling of RF integrated structures with fine metallic details using time-domain simulators is addressed. The key features identified as difficulties in modelling metallic structures in these techniques are dielectric and metal loss and complexity of geometry. A method to model loss that involves the use of a quasi-static simulator to identify correction factors that can be applied to a time domain simulator is presented. In addition, a novel MRTD subcell method is presented that can be used to simulate fine metallic structures and other subcell effects such as the presented correction factors. An example simulation of a finely detailed structure using this technique is presented. Copyright © 2004 John Wiley & Sons, Ltd.

Retroperitoneal Laparoscopic Lateral Approach to the Lumbar Spine: A New Approach, Technique, and Clinical Trial (2000)

A retroperitoneal laparoscopic (retroperitoneoscopic) lateral approach to achieve decompression for a far lateral disk lesion in the lumbar spine or to remove a paravertebral neurinoma without disrupting the facet is described. The operating space is maintained using a powered mechanical lift and a flat inflatable retractor mainly to make a longitudinal separation between the psoas major and the quadratus lumborum. This technique has been performed successfully in 22 cases using retroperitoneoscopy. The best indications of this new procedure are lateral disk herniation at the L5-S1 level or around the conus medullaris at the L1-L2 level. The described procedure provides adequate exposure necessary for extraforaminal exploration, discectomy, and nerve root decompression, and it is sufficient for treating extreme lateral lumbar herniation localized to the L1-S1 level and spinal nerve root tumors.
Establishment of Safety Information Integrated Control Center through Drones (2019)

현재 드론은 다양한 분야에서 활용되고 있으며, 그 범위가 더욱 확대되고 있다. 본 연구의 목적은 드론을 통해 수집되는 안전정보를 지역사회의 통합관제센터에서 활용하는 방안을 논의하는데 있다. 문헌연구를 통해 기술적인 분야는 제외하고 드론을 활용한 지역사회의 안전 개선에 중점을 두고 논의하였다. 대부분의 지방자치단체에서는 안전을 위해 통합관제센터를 구축하여 운영하고 있다. 통합관제센터는 CCTV를 기반으로 시스템이 마련되어 있으며, 대부분 영상정보를 통해 안전활동이 이루어지고 있다. 드론을 통해 수집되는 다양한 안전정보를 통합관제센터에서 활용할 수 있도록 시스템이 필요하다. 따라서 드론을 지역사회 안전 정보 수집에 활용하고, 그 정보를 통합관리할 필요가 있다. 무엇보다 드론을 활용하는데 인력적인 측면을 간과해서는 안 되며, 교육훈련과 연구 역량의 향상에 지속적인 지원이 필요하다.These days, drones are being used in various fields, also the range has been further expanded. As the initial, technical and legal limitations are gradually resolved, the roles are being emphasized throughout the safety activities as well as crimes in the community. The purpose of this study is to discuss the use of safety information collected through drone in the integrated control center for the community. With the exception of the technical field, literature reviews have focused on improving community safety by using drones. The most of local governments has established and operate an integrated control center for local safety. There is a need for a system that can utilize various safety information gathered through drones in integrated control center. The integrated control center has a system based on CCTV, and the most of them have safety activities through video information. The Integrated Control Center is installed in local governments and integrates and links CCTV installed for various purposes such as living safety, traffic control, parking control, waste disposal, disaster monitoring, facility management, and child protection. Therefore, it is necessary to utilize the drones to collect safety information and to manage the information integrally. By monitoring the area in real time, it can prevent various crimes and illegal activities in advance. In addition, the risk can be quickly recognized, and the situation can be quickly notified to relevant authorities. It is positive to establish organic information sharing and cooperation system among related organizations. First of all, we should not overlook the manpower aspect of using drones, and we need continuous support to improve our training and research capabilities.
Constitutive expression of cytochrome P450 1B1 endows testicular Leydig cells with susceptibility to 7,12-dimethylbenzanthracene-induced cell death (2022)

Testicular Leydig cells produce testosterone through the participation of steroidogenic proteins. The CYP1B1 enzyme has been shown to catalyze 7,12-dimethylbenzanthracene (DMBA), a representative polycyclic aromatic hydrocarbon. We hypothesized that exposure to DMBA causes Leydig cell cytotoxicity through activation of CYP1B1. Leydig cells were exposed to various concentrations of DMBA for the induction of CYP1B1 expression and activity. The status of CYP1B1 function was monitored by evaluation of cytotoxicity-mediated cell death. Our data show that exposure to DMBA causes cytotoxicity in Leydig cells by CYP1B1 activation. DMBA evoked a significant increase in the generation of reactive oxygen species (ROS) by which the depolarization of mitochondrial membrane potential (MMP) is initiated and caspase-3 activation is augmented. The knockdown of CYP1B1 expression resulted in the suppression of DMBA-induced apoptosis via reduced p53 activation and caspase-3 activation, suggesting that a final metabolite of DMBA (i.e., DMBA-DE) bioactivated by CYP1B1 induces p53 activation by binding to DNA and subsequently causing apoptosis via caspase-3 activation. This finding provides evidence for constitutive expression of CYP1B1 in Leydig cells, which is a trait that only requires an initiating signal for its activity. Further research on CYP1B1 activation-provoked steroid metabolism in Leydig cells may provide decisive clues for elucidating its innate function.
Dynamic feature-adaptive subdivision (2015)

Feature-adaptive subdivision (FAS) is one of the state-of-the art real-time rendering methods for subdivision surfaces on modern GPUs. It enables efficient and accurate rendering of subdivision surfaces in many interactive applications, such as video games or authoring tools. In this paper, we present dynamic feature-adaptive subdivision (DFAS), which improves upon FAS by enabling an independent subdivision depth for every irregularity. Our subdivision kernels fill a dynamic patch buffer on-the-fly with the appropriate number of patches corresponding to the chosen level-of-detail scheme. By reducing the number of generated and processed patches, DFAS significantly improves upon the performance of static FAS.

Detection of Trace Molecules in the Atmosphere by Nonlinear Raman Spectroscopy without a Tunable Laser. (1999)

A new technique for nonlinear Raman spectroscopy is proposed and discussed theoretically in terms of the detection of gas molecules in atmospheric pressure. In the proposed scheme, only a pulsed Nd: YAG laser is used as a pumping source, and instead of a tunable laser, a Raman shifter filled with the sametype of gas as that to be detected automatically generates the Raman shifted radiation. The detection limits of H2for SRGS (Stimulated Raman Gain Spectroscopy), PARS (Photo-Acoustic Raman Spectroscopy), and CARS (Coherent Anti-Stokes Raman Spectroscopy) are demonstrated experimentally, and the ppm order detection limit can be achieved by PARS. Although the sensitivity of CARS is smaller than that of PARS, the signal tonoise ratio in higher concentration is more effective.
Introduction (2002)

In Ezra Stoller's masterful photograph, the Healy Guest (or "Cocoon") House perches at the very edge of the Bayou Louise. In the interior of the house, visible through an opening that can be seen on the extreme right of the image, a pair of light-weight metal chairs and a table stand out in silhouette against the glass front wall. In the foreground of the photograph, on a deck cantilevered well out over the water, a pair of slippers, a book casually laid down on a low seating area, and a group of oranges on a glass table all suggest an occupant who has just ducked into the house but will be back momentarily to pick up the peeled orange, re-open the book, and settle contentedly back on the low bench to read. In the background, behind the receding lines of the building's window louvers and diagonal tie rods, a boat tethered to a landing punctuates a nearly still stretch of water. Beyond this a sandy beach and a cluster of trees on the horizon give way to an immense sky dramatically filled with clouds.KeywordsRoof StructureEarly HouseCurrent RevivalTable StandHanging RoofThese keywords were added by machine and not by the authors.

Synthesis of an Unlocked Nucleic Acid Terpyridine Monomer and Binding of Divalent Metal Ion in Nucleic Acid Duplexes (2009)

Herein we present the synthesis and thermal stability studies of modified oligonucleotides containing an unlocked nucleic acid (UNA) terpyridine monomer. Incorporation of this monomer into both strands of a DNA duplex allowed reversible thermal stability modulation upon addition or withdrawal of divalent metal ions. A likely explanation of this phenomenon is interstrand complexation between two terpyridine units and a metal ion. This system could be useful in the development of nanoscale devices based on DNA hybridization.
Evaluation of Humidity Sensor Based on PVP-RGO Nanocomposites (2018)

This paper describes the humidity sensing properties of one step in situ synthesized poly (N-vinyl pyrrolidone)-reduced graphene oxide (PVP-RGO) nanocomposites. Different PVP-RGO nanocomposites were obtained by varying PVP/GO weight %ratio as x/50 mg, wherein x = 25, 50, and 75 mg, respectively. The real-time adsorption kinetics of the water molecules during the humidity sensing were also discussed using Elovich model, pseudo first and second order equations. The increase in humidity response of 1.5 PVP-RGO nanocomposite is attributed to the presence of large amount of oxygen functionalities. The above observation was corroborated using spectroscopic analysis. The optimized PVP-RGO nanocomposite showed faster response kinetics with response and recovery times of 10 and 20 s, respectively. The present humidity sensor shows remarkable linearity over the range of 20-90%RH. More specifically, sensitivity was correlated with oxygen functionalities created due to variation of PVP during the functionalization of RGO nanosheets.
Specificity and formation of unusual amino acids of an amide ligation strategy for unprotected peptides (1995)

An important step in the recently developed ligation strategy known as domain ligation strategy to link unprotected peptide segments without activation is the ring formation between the C-terminal ester aldehyde and the N-terminal amino acid bearing a beta-thiol or beta-hydroxide. A new method was developed to define the specificity of this reaction using a dye-labeled alanyl ester aldehyde to react with libraries of 400 dipeptides which contained all dipeptide combinations of the 20 genetically coded amino acids. Three different ester aldehydes of the dye-labeled alanine: alpha-formylmethyl (FM), beta-formylethyl (FE), and beta,beta,beta-dimethyl and formylethyl esters (DFE), were examined. The DFE ester was overly hindered and reacted with N-terminal Cys dipeptides (Cys-X). Interestingly, it also reacted slowly with the sequences of X-Gly where Gly was the second amino acid and the X-Gly amide bond participated in the ring formation. Although the FE ester reacted similarly as the FM ester in the ring formation, the subsequent O,N-acyl transfer was at least 30-fold slower than those of the FM-ester. The FM alpha-formyl methyl ester was the most suitable ester and was reactive with dipeptides of six N-terminal amino acids: Cys, Thr, Trp, Ser, His and Asn. The order and extent of their reactivity were highly dependent on pH, solvent and neighboring participation by the adjacent amino acid. In general, they could be divided into three categories. (1) N-Terminal Cys and Thr were the most reactive.(ABSTRACT TRUNCATED AT 250 WORDS)

Robust Method for Wellhead Loads Estimation Based on Lower Stack Motion Measurements (2020)

Abstract Estimating wellhead loads from lower stack motion measurements is a practical and cost-effective approach. In this paper, a new method is proposed, which is based on system identification techniques rather than Newtonian mechanics, thus omitting reliance on uncertain and variable quantities such as lowerflex joint stiffness/damping, riser and drill pipe tension etc. The proposed method is simple and easy to apply, while maintaining accuracy. Both simulation and real-world measurement data are utilized to demonstrate and evaluate the method.
Fourier Properties of Symmetric-Geometry Computed Tomography and Its Linogram Reconstruction With Neural Network (2020)

In this work, we investigate the Fourier properties of a symmetric-geometry computed tomography (SGCT) with linearly distributed source and detector in a stationary configuration. A linkage between the 1D Fourier Transform of a weighted projection from SGCT and the 2D Fourier Transform of a deformed object is established in a simple mathematical form (i.e., the Fourier slice theorem for SGCT). Based on its Fourier slice theorem and its unique data sampling in the Fourier space, a Linogram-based Fourier reconstruction method is derived for SGCT. We demonstrate that the entire Linogram reconstruction process can be embedded as known operators into an end-to-end neural network. As a learning-based approach, the proposed Linogram-Net has capability of improving CT image quality for non-ideal imaging scenarios, a limited-angle SGCT for instance, through combining weights learning in the projection domain and loss minimization in the image domain. Numerical simulations and physical experiments on an SGCT prototype platform showed that our proposed Linogram-based method can achieve accurate reconstruction from a dual-SGCT scan and can greatly reduce computational complexity when compared with the filtered backprojection type reconstruction. The Linogram-Net achieved accurate reconstruction when projection data are complete and significantly suppressed image artifacts from a limited-angle SGCT scan mimicked by using a clinical CT dataset, with the average CT number error in the selected regions of interest reduced from 67.7 Hounsfield Units (HU) to 28.7 HU, and the average normalized mean square error of overall images reduced from 4.21e-3 to 2.65e-3.
Two-year follow-up of Sanfilippo Disease patients treated with a genistein-rich isoflavone extract: Assessment of effects on cognitive functions and general status of patients (2011)

We conclude that the treatment of Sanfilippo patients with a genistein-rich soy isoflavone extract (called gene expression-targeted isoflavone therapy [GET IT]) may be effective in either inhibition (in some patients) or slowing down (in other patients) of behavioral and cognitive problems over a longer period. An increased dose of genistein may improve the efficacy of the treatment.
