Living alongside more affluent neighbors predicts greater involvement in antisocial behavior among low‐income boys (2015)

Findings suggest that efforts to create more economically mixed communities for children, if not properly supported, may have iatrogenic effects on boys' antisocial behavior.

Fibonacci codes for synchronization control (1965)

A new family of codes is described for representing serial binary data, subject to constraints on the maximum separation between successive changes in value <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">(0 \rightarrow 1, 1 \rightarrow</tex> , or both), or between successive like digits ( <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</tex> 's, <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</tex> 's, or both). These codes have application to the recording or transmission of digital data without an accompanying clock. In such cases, the clock must be regenerated during reading (receiving, decoding), and its accuracy controlled directly from the data itself. The codes developed for this type of synchronization are shown to be optimal, and to require a very small amount of redundancy. Their encoders and decoders are not unreasonably complex, and they can be easily extended to include simple error detection or correction for almost the same additional cost as is required for arbitrary data.
Plant C-N Hydrolases and the Identification of a Plant N-Carbamoylputrescine Amidohydrolase Involved in Polyamine Biosynthesis (2003)

A nitrilase-like protein from Arabidopsis thaliana (NLP1) was expressed in Escherichia coli as a His(6)-tagged protein and purified to apparent homogeneity by Ni(2+)-chelate affinity chromatography. The purified enzyme showed N-carbamoylputrescine amidohydrolase activity, an enzyme involved in the biosynthesis of polyamines in plants and bacteria. N-carbamoylputrescine amidohydrolase activity was confirmed by identification of two of the three occurring products, namely putrescine and ammonia. In contrast, no enzymatic activity could be detected when applying various compounds including nitriles, amines, and amides as well as other N-carbamoyl compounds, indicating the specificity of the enzyme for N-carbamoylputrescine. Like the homologous beta-alanine synthases, NLP1 showed positive cooperativity toward its substrate. The native enzyme had a molecular mass of 279 kDa as shown by blue-native polyacrylamide gel electrophoresis, indicating a complex of eight monomers. Expression of the NLP1 gene was found in all organs investigated, but it was not induced upon osmotic stress, which is known to induce biosynthesis of putrescine. This is the first report of cloning and expression of a plant N-carbamoylputrescine amidohydrolase and the first time that N-carbamoylputrescine amidohydrolase activity of a recombinant protein could be shown in vitro. NLP1 is one of the two missing links in the arginine decarboxylase pathway of putrescine biosynthesis in higher plants.
IDDF2018-ABS-0230 Transglutaminase 2 modulates inflammation-associated angiogenesis via VEGFR2 pathway in crohn’s disease (2018)

<h3>Background</h3> Angiogenesis is a vital component of the pathogenesis of inflammatory bowel disease(IBD). Vascular endothelial growth factor A(VEGF-A) and its receptors VEGFR2 are the pivotal component of angiogenesis in IBD. Recent studies suggest that transglutaminase 2 regulates angiogenesis in cancer and physiological conditions through VEGFR2 pathway. However, whether transglutaminase 2 are involved in this process of IBD remains elusive. <h3>Methods</h3> We use real-time PCR and Western blotting to validate the expression of TGM2 in CD patients‘ biopsy samples and TNBS-induced murine colitis. Furthermore, we use immunohistochemistry and immunofluorescence of surgical specimen and TNBS/DSS-induced murine colitis section to investigate the location of TGM2 in CD. To investigate the role of TGM2 in CD, human intestinal microvascular endothelial cells(HIMEC) and mouse intestinal microvascular endothelial cells(MIMEC) was treated with inflammatory cytokines. Finally, TNBS murine colitis model was treated with IL-9 neutralising antibody and weight loss, intestine length, as well as microvessel density, was evaluated after treatment. <h3>Results</h3> We found that the TGM2 was up-regulated in colonic mucosa of CD patients and TNBS-induced colitis. In addition, TGM2 expression mainly locates in microvessel. (figure 1) Furthermore, after treating with IL-9, TGM2 and VEGFR2 were significantly upgraded in HIMEC and MIMEC. In contrary, weight loss, intestine length, as well as microvessel density in TNBS murine colitis model, was significantly improved after treating with IL-9 neutralising antibody. <h3>Conclusions</h3> Our findings provide new evidence that TGM2 plays an important role in angiogenesis in CD, thus TGM2 may represent a novel therapeutic target for IBD.

Niacin, Nicotinamide, and Nicotinic Acid (2000)

Abstract The history of the discovery of nicotinic acid and nicotinamide is unusual in that these compounds were first synthesized and later their biological significance was elucidated. In the early part of the twentieth century, the importance of nicotinamide in the treatment of pellagra was determined. Specifically, nicotinic acid and nicotinic amide are constituents of the cofactors NAD and NADH which are required for many enzymatic reactions and the particular role of these cofactors is discussed. The key intermediate in the industrial synthesis of these compounds are alkyl pyridines. Methods of preparation of these intermediates as well as methods to functionalize the side chain are reviewed. Both biological and chemical approaches have found utility in this application. A review of analytical methodology is presented. An overview of the biological effects of these substances is presented. Despite their structural similarities, the safety and toxicity of these compounds are quite different and these consequences are highlighted.
A Practical Incremental Learning Framework For Sparse Entity Extraction (2018)

This work addresses challenges arising from extracting entities from textual data, including the high cost of data annotation, model accuracy, selecting appropriate evaluation criteria, and the overall quality of annotation. We present a framework that integrates Entity Set Expansion (ESE) and Active Learning (AL) to reduce the annotation cost of sparse data and provide an online evaluation method as feedback. This incremental and interactive learning framework allows for rapid annotation and subsequent extraction of sparse data while maintaining high accuracy. We evaluate our framework on three publicly available datasets and show that it drastically reduces the cost of sparse entity annotation by an average of 85% and 45% to reach 0.9 and 1.0 F-Scores respectively. Moreover, the method exhibited robust performance across all datasets.
Gain and saturation intensity measurements of a discharge pumped F2 laser at high excitation rates (1992)

Small-signal gain and saturation intensity of a discharge pumped F2 laser at 157 nm, operated at high pressures (&amp;lt;10 atm) and high excitation rates (7–39 MW/cm3), were measured in an oscillator-amplifier configuration. The small-signal net gain reaches 37±4%/cm at an excitation rate of ∼26 MW/cm3 for a 6-atm laser gas. A saturation intensity, which depends on a nonsaturable absorption coefficient, was estimated.
On blind equalization of MIMO channels (2002)

This paper investigates adaptive blind equalization for multiple-input and multiple-output (MIMO) channels and its application to blind separation of multiple signals received by antenna arrays in communication systems. The performance analysis of the CMA equalizer used in MIMO channels is first presented. Our analysis results indicate that for the MIMO FIR channels satisfying certain conditions, the MIMO-CMA FIR equalizer is able to remove the ISI and co-channel interference regardless of the initial setting of the blind equalizer. To recover all input signals simultaneously, a novel MIMO channel blind equalization algorithm is then developed. The global convergence of the new algorithm for MIMO channels is proved. Hence, the new blind equalization algorithm for MIMO channels can be applied to separate and equalize the signals received by antenna arrays in communication systems. Finally, computer simulations are presented to confirm our analysis and illustrate the performance of the new algorithm.
Enabling privacy through transparency (2014)

Many access control systems, particularly those utilized in hospital environments, exercise optimistic security, because preventing access to information may have undesirable consequences. However, in the wrong hands, these over-broad permissions may result in privacy violations. To circumvent this issue, we have developed Privacy Enabling Transparent Systems (PETS) that makes transparency a key component in systems architectures. PETS is built on open web standards and introduces the Provenance Tracking Network (PTN), an open global trusted network of peer servers, to the traditional web stack. Websites that conform to the architecture communicate information about transactions for any sensitive data items with the PTN. These usage logs are stored in a decentralized manner and can later be queried to check compliance with individual usage restrictions that assert no unauthorized data transfer or usage has taken place. PETS enables data consumers to be transparent with regard to data usages and determine if there has been privacy violations after the fact. We conducted a user study on a healthcare data application built using PETS to see if transparency on access and usage data satisfies expectations of user privacy.
Digital baseband compensation of frequency-dependent joint TX/RX I/Q imbalance in beamforming MIMO OFDM transceivers (2012)

In this paper, we investigate the effects of asymmetric frequency-dependent joint transmit-receive I/Q imbalance on the performance of beamforming MIMO-OFDM systems. We derive the throughput-maximizing transmit/receive beamforming coefficients taking into account I/Q imbalance effects. In addition, we propose a low-complexity pilot-aided scheme for the estimation of the channel and I/Q imbalance parameters. Our simulation results demonstrate the effectiveness of the proposed generalized beamforming scheme in mitigating I/Q imbalance effects.
Analysis of camera's images influenced by light variation (2007)

Cameras are excellent sensors for robots in unstructured environment such as human living space. However, a camera being extreme sensitive to light illumination variation restricts robots in human life. In this paper, color image of a camera influenced by light variation is studied for practical applications used as robot sensors in future. Firstly, the influence of camera's image data due to varying light illumination is analyzed to build a database consisted of the sets of threshold values. In the analysis, the change rules of the YUV components due to varying illumination is induced for color segmentation of robots against unstable lighting.
Enhanced the electrochemical performance and stability of supercapattery device with carbon nanotube/cobalt‐manganese sulfide‐based composite electrode material (2022)

Supercapattery devices have gained extraordinary attention due to high power and energy densities with excellent cycle stability compared to conventional storage devices. Herein, the cobalt manganese sulfide (CoMnS) is synthesized using the hydrothermal method, and designed the supercapattery device. Further, carbon nanotubes (CNTs) are used to make a composite with CoMnS and measure the electrochemical characteristics. A high value of specific capacity (Qs = 934.7 C/g) is estimated at a current density of 1.5 A/g in the CoMnS/CNT composite sample, which is higher than the reference sample. Besides, the asymmetric supercapattery device is designed to measure the real device. In CoMnS/CNT//AC supercapattery device, the conceived value of the Qs is 137.06 C/g with an extraordinary energy density of 38.4 Wh/kg and power density of 1120 W/kg. A reliability test is conducted to explore stability, and the device is subjected to 10 000 charging/discharging cycles and observed that 84% of the nominal capacity is maintained. The composite of sulfides with CNTs provides a unique platform to design a unique and novel electrode material for supercapattery and other energy storage devices.
Thermal transport exceeding bulk heat conduction due to nonthermal micro/nanoscale phonon populations (2020)

While classical size effects usually lead to a reduced effective thermal conductivity, we report here that nonthermal phonon populations produced by a micro/nanoscale heat source can lead to enhanced heat conduction, exceeding the prediction from Fourier's law. We study nondiffusive thermal transport by phonons at small distances within the framework of the Boltzmann transport equation (BTE) and demonstrate that the transport is significantly affected by the distribution of phonons emitted by the source. We discuss analytical solutions of the steady-state BTE for a source with a sinusoidal spatial profile, as well as for a three-dimensional Gaussian “hot spot,” and provide numerical results for single crystal silicon at room temperature. If a micro/nanoscale heat source produces a thermal phonon distribution, it gets hotter than that predicted by the heat diffusion equation; however, if the source predominantly produces low-frequency acoustic phonons with long mean free paths, it may get significantly cooler than that predicted by the heat equation, yielding an enhanced heat transport beyond bulk heat conduction.
Single Event Transients Induced by Picosecond Pulsed X-Ray Absorption in III&#x2013;V<newline/> Heterojunction Transistors (2012)

We perform measurements which show that focused, picosecond pulses of x-rays can be used to generate single event transients (SET) in a GaAs heterostructure field effect transistor (HFET) and a GaN high electron mobility transistor. X-ray pulses with photon energies of 8, 10 and 12 keV from the Advanced Photon Source at Argonne National Laboratory were used to excite transients. SETs are observed when x-ray pulses are incident upon metal layers above sensitive areas on the transistors. We use focused ion beam (FIB) cross-sectioning and scanning transmission electron microscopy energy dispersive x-ray spectroscopy (STEM-EDXS) to determine the compositional structure of the devices. We present a first order analysis of energy deposition in the devices and correlate it to the transient response to make preliminary interpretations of the results. We compare the x-ray transients from the GaAs HFET with transients generated by 750 nm and 870 nm femtosecond laser pulses. We also present results on the total dose susceptibility of the GaN HEMTs.
Gain and loss of propagating electromagnetic wave along a hollow silver nanorod (2009)

Using the discrete dipole approximation (DDA) method, we examined the electromagnetic wave propagation along a hollow silver nanorod with subwavelength dimensions. The calculations show that light may propagate along the hollow nanorod with growing intensities. The influences of the shape, dimension, and length of the rod on the resonance wavelength and the enhanced local electric field, |E|(2), along the rod were investigated. The resonance wavelength monotonically red-shifted with increasing rod dimension perpendicular to the polarization direction. The resonance peak initially shifted to blue with increasing rod dimension parallel to the polarization direction and eventually shifted to red after a threshold value. For the hollow rods with similar cross sections, the square and rectangular rods produced greater enhanced electric fields along the rods. For the rectangular hollow rods with a fixed 10 nm thick shell and 100 nm long edge perpendicular to the polarization direction, light propagates along the outer surface of the rods when the parallel edge length is larger than 50 nm. The propagating wave with higher intensities is confined inside the hollow rods when the parallel edge length is less than 50 nm.
Outcomes of Femoral Head Marrow Stimulation Techniques at Minimum 2-Year Follow-up (2017)

This study compared patients who underwent femoral head microfracture with a control group of patients who did not require microfracture. Patients had more than 2 years of follow-up. The patient groups had similar demographic and radiographic features, including sex, age within 5 years, body mass index within 5 points, equal Tönnis grade, lateral center edge angle within 5°, labral treatment, and capsular closure vs release. Inclusion criteria were a minimum of 2 years of follow-up, Outerbridge grade IV cartilage damage, and femoral head marrow stimulation technique performed at the time of arthroscopy. Exclusion criteria were revision surgery, dysplasia, Tönnis grade of greater than 1, protrusio or profunda acetabuli, Perthes disease of the hip, slipped capital femoral epiphysis, abductor tear, and avascular necrosis of the hip. Patient-reported outcomes included modified Harris hip score, nonarthritic hip score, hip outcome score-activity of daily living subscale, hip outcome score-sports subscale, and visual analog scale score for pain. Fifteen patients had femoral head microfracture with more than 2 years of follow-up. Mean improvements in modified Harris hip score, nonarthritic hip score, hip outcome score-sports subscale, and visual analog scale score were 17.1, 19.4, 30.5, and 2.8, respectively, for the microfracture group compared with 11.8, 18.5, 22.2, and 3.0, respectively, for the control group. Both groups showed statistically significant improvement (P<.05) for all patient-reported outcomes, and no significant difference was found between the 2 patient groups at latest follow-up. Two patients in the microfracture group vs 3 patients in the control required hip arthroplasty. Femoral head microfracture is a technically difficult procedure, but when performed correctly, the results are similar to those of patients who do not require microfracture. Further study of femoral head microfracture is necessary to confirm these encouraging short-term outcomes. [Orthopedics. 2018; 41(1):e70-e76.].
The degradation of organophosphorus pesticides by hydrogen peroxide I. Characters and influencing factors of the degradation (2004)

The characters and influencing factors of the degredation of organophosphorus pesticides of methamidophos, chlorpyrifos and monocrotophos by hydrogen peroxide (H_2O_2) were studied. The result showed that hydrogen peroxide had highly activity in degrading the organophosphorus pesticides, and the degradation rates were 5-13 times of that of the treatment without H_2O_2.Ultraviolet radiation could significantly increase the degradation of the pesticides, which were 3-9 times of the treatment with daylight, and 10-20 times of the treatment without light. When the initial pH-value was at 4-6,the lest degradation rates were gotten, while the rates increased with high basic condition. However, the degradation was restrained with the use of O_2. The degradation rates increased with the time of reaction. The degradation of pesticides was expected to get even better results at higher concentration of H_2O_2 concentration, and the degradation rates was decreased with more chemical added, however, the degraded amount increased.
False-positive 123I-metaiodobenzylguanidine scintigraphy in a patient with a gastrointestinal stromal tumor presenting as a left adrenal incidentaloma (2023)

Anatomic structures and tumors that develop in neighboring tissues to the adrenal glands may be confused with primary adrenal tumors. 123I- metaiodobenzylguanidine (MIBG) scintigraphy is specific for diagnosing pheochromocytomas and paragangliomas; however, it has been reported that 123I-MIBG may accumulate in neuroendocrine tumors as well as other tumors. Clinicians should recognize the limitations of imaging studies and the uncertainty of an imaging-based preoperative diagnosis.
