Lessons from Structural Genomics (2009)

A decade of structural genomics, the large-scale determination of protein structures, has generated a wealth of data and many important lessons for structural biology and for future large-scale projects. These lessons include a confirmation that it is possible to construct large-scale facilities that can determine the structures of a hundred or more proteins per year, that these structures can be of high quality, and that these structures can have an important impact. Technology development has played a critical role in structural genomics, the difficulties at each step of determining a structure of a particular protein can be quantified, and validation of technologies is nearly as important as the technologies themselves. Finally, rapid deposition of data in public databases has increased the impact and usefulness of the data and international cooperation has advanced the field and improved data sharing.
Facile Preparation of Epoxide-Functionalized Surfaces via Photocurable Copolymer Coatings and Subsequent Immobilization of Iminodiacetic Acids (2018)

Herein, we report a simple coat/cure preparation of epoxide-functionalized surfaces using a photocurable copolymer technology. The photocurable copolymer, poly(glycidyl methacrylate- co-butyl acrylate- co-4-benzoylphenyl methacrylate) (GBB), was synthesized by single electron transfer-living radical polymerization (SET-LRP). The epoxide content in the copolymer was tuned by controlling the content of glycidyl methacrylate. Three copolymers, GBB(1), GBB(2), and GBB(3), with epoxide contents of 22, 63, and 91 mol %, respectively, were cast onto polypropylene films and photocured by UV-light exposure. Subsequently, iminodiacetic acids (IDA) were immobilized onto the GBB-coated materials via a ring-opening reaction. The IDA-functionalized coatings GBB(1)-IDA, GBB(2)-IDA, and GBB(3)-IDA presented IDA contents of 1.47 ± 0.08, 18.67 ± 1.46, and 49.05 ± 2.88 nmol/cm<sup>2</sup>, respectively, which increased as the epoxide content increased. The IDA-functionalized GBB coatings exhibited metal chelating capability toward transition metal ions (e.g., iron and copper). The reported photocurable copolymer technology offers a facile and tunable preparation of epoxide-functionalized surfaces, with potential extended applications in biopatterning, active packaging, and nanotechnology.
Dioxygen bound cobalt corroles (2016)

Two cobalt-dioxygen adducts, [CoH<sub>8</sub>]-O<sub>2</sub> and [CoCl<sub>8</sub>]-O<sub>2</sub>, chelated by electron-rich and electron-poor corroles, respectively, were isolated in solution. Characterization by resonance Raman (rR) and EPR spectroscopy, together with DFT analyses, point towards (corrole) cobalt(iii)-O<sub>2</sub>˙<sup>-</sup> structures in both cases. The most significant insight was obtained from the Co-O and O-O stretching frequencies, which revealed that the Co-O bond in [CoH<sub>8</sub>]-O<sub>2</sub> is somewhat stronger than in [CoCl<sub>8</sub>]-O<sub>2</sub> and its O-O is weaker, but also that the differences are truly minute (8-10 cm<sup>-1</sup> for the O-O stretch). These conclusions are vital regarding the various applications that rely on efficient reduction of molecular oxygen. In particular, these kinds of cobalt complexes are perfectly suited for serving as electrocatalysts that may be tuned to operate at minimal overpotential without losing almost anything in terms of activity.
Obesity Does Not Influence Delayed Gastric Emptying Following Pancreatoduodenectomy (2022)

Background: The data about obesity on postoperative outcome after pancreatoduodenectomy (PD) are inconsistent, specifically in relation to gastric motility and delayed gastric emptying (DGE). Methods: Two hundred and eleven patients were included in the study and patients were retrospectively analyzed in respect to pre-existing obesity (obese patients having a body mass index (BMI) ≥ 30 kg/m2 vs. non-obese patients having a BMI < 30 kg/m2, n = 34, 16% vs. n = 177, 84%) in relation to demographic factors, comorbidities, intraoperative characteristics, mortality and postoperative complications with special emphasis on DGE. Results: Obese patients were more likely to develop clinically relevant pancreatic fistula grade B/C (p = 0.008) and intraabdominal abscess formations (p = 0.017). However, clinically relevant DGE grade B/C did not differ (p = 0.231) and, specifically, first day of solid food intake (p = 0.195), duration of intraoperative administered nasogastric tube (NGT) (p = 0.708), rate of re-insertion of NGT (0.123), total length of NGT (p = 0.471) or the need for parenteral nutrition (p = 0.815) were equally distributed. Moreover, mortality (p = 1.000) did not differ between the two groups. Conclusions: Obese patients do not show a higher mortality rate and are not at higher risk to develop DGE. We thus show that in our study, PD is feasible in the obese patient in regard to postoperative outcome with special emphasis on DGE.
A flip-chip MMIC design with CPW technology in the W-band (2002)

We designed and fabricated a W-band flip-chip MMIC amplifier with a coplanar waveguide (CPW) transmission line using 0.15 /spl mu/m InGaP-InGaAs HEMT technology. In addition, we present a test structure for obtaining an accurate flip-chip CPW line model, and demonstrate a two-stage flip-chip MMIC amplifier with a gain of 12 dB at 79 GHz to validate this model.
TRBP Control of PACT-Induced Phosphorylation of Protein Kinase R Is Reversed by Stress (2008)

The TAR RNA binding Protein, TRBP, inhibits the activity of the interferon-induced protein kinase R (PKR), whereas the PKR activator, PACT, activates its function. TRBP and PACT also bind to each other through their double-stranded RNA binding domains (dsRBDs) and their Medipal domains, which may influence their activity on PKR. In a human immunodeficiency virus (HIV) long terminal repeat-luciferase assay, PACT unexpectedly reversed PKR-mediated inhibition of gene expression. In a translation inhibition assay in HeLa cells, PACT lacking the 13 C-terminal amino acids (PACTDelta13), but not full-length PACT, activated PKR and enhanced interferon-mediated repression. In contrast, in the astrocytic U251MG cells that express low TRBP levels, both proteins activate PKR, but PACTDelta13 is stronger. Immunoprecipitation assays and yeast two-hybrid assays show that TRBP and PACTDelta13 interact very weakly due to a loss of binding in the Medipal domain. PACT-induced PKR phosphorylation was restored in Tarbp2(-/-) murine tail fibroblasts and in HEK293T or HeLa cells when TRBP expression was reduced by RNA interference. In HEK293T and HeLa cells, arsenite, peroxide, and serum starvation-mediated stresses dissociated the TRBP-PACT interaction and increased PACT-induced PKR activation, demonstrating the relevance of this control in a physiological context. Our results demonstrate that in cells, TRBP controls PACT activation of PKR, an activity that is reversed by stress.
Reemergence of Chikungunya Virus in Bo, Sierra Leone (2013)

We diagnosed 400 possible IgM-positive cases of chikungunya virus in Bo, Sierra Leone, during July 2012-January 2013 by using lateral flow immunoassays. Cases detected likely represent only a small fraction of total cases. Further laboratory testing is required to confirm this outbreak and characterize the virus.
Editorial: Use of Azathioprine and 6MP in Postoperative Crohn's: Changing Natural History or Just Along for the Ride? (2009)

There is currently no standard of care for the management of postoperative Crohn's disease (CD), partly because data from definitive trials are lacking. Despite the absence of such data, many experts advocate the selective use of azathioprine (AZA) or 6-mercaptopurine (6MP) in the prevention of postoperative recurrence in patients with risk factors for recurrence. In the current issue of The American Journal of Gastroenterology, Peyrin-Biroulet and colleagues quantified the efficacy of AZA/6MP in this setting by performing a meta-analysis of AZA/6MP trials. The implications of this work, both for the current management of postoperative Crohn's and the future design of clinical trials that are definitive in this group of patients, are discussed.
[The predictive value of warning scores for intensive care unit admission in coronavirus disease 2019 patients]. (2023)

To evaluate the predictive value of early warning scores for intensive care unit (ICU) admission in patients with coronavirus disease 2019 (COVID-19). For COVID-19 patients who were admitted to Shijiazhuang People's Hospital from January 2021 to February 2021, national early warning score (NEWS), national early warning score 2 (NEWS2), rapid emergency medicine score (REMS), quick sepsis-related organ failure (qSOFA), altered consciousness, blood urea nitrogen, respiratory rate, blood pressure, and age-65 (CURB-65) were used to evaluate the inpatient condition and the predictive value for ICU admission. A total of 368 patients were included, and 32 patients (8.7%) were transferred to the ICU. The median age was 49.0 (34.0,61.0) years. The scores of NEWS, NEWS2, REMS, and CURB-65 were 1 (0, 2), 1 (0, 2), 4 (2, 6) and 0 (0, 1), respectively. The receiver operating characteristic (ROC) cure (AUC) was used to evaluate the predictive value in detecting patients who are at risk of being transferred to the ICU. Area under the ROC AUC of NEWS was 0.756, sensitivity 65.6%, and specificity 71.3%. ROC AUC of NEWS2 was 0.732, sensitivity 62.5%, and specificity 61.3%. ROC AUC of REMS was 0.787, sensitivity 84.4%, and specificity 64.6%. ROC AUC of CURB-65 was 0.814, sensitivity 81.3%, and specificity 76.8%. The predictive value of NEWS and NEWS2 combined with age were significantly improved. The ROC AUC of NEWS combined with age was 0.885, sensitivity 85.1%, and specificity 75.0%. The ROC AUC of NEWS2 combined with age was 0.883, sensitivity 84.2%, and specificity 75.0%. NEWS and NEWS2 combined with age can be used as a predictive tool for whether COVID-19 patients will be admitted to the ICU.
Multiprocessor raster plotting (1992)

A scalable multiprocessor raster image processor that generates printed circuit plots in alternating band buffers is described. Synchronous raster plotting systems and the development of mask creation for producing printed circuits are reviewed. The general architecture of the multiprocessing system that rasterizes printed circuit plot descriptions, and its graphics, load prediction, and facet size computation operations are discussed. Performance analysis results of two versions of the multiprocessor architecture, one with four rasterization transputers and the other with eight, are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

A kidney transplant recipient with renal medullary viral cytopathic changes (2016)

We present a case of JC polyomavirus (JCV)-associated nephropathy (PyVAN) in an asymptomatic deceased-donor kidney transplant recipient. Despite the presence of viral cytopathic effect in the kidney biopsy and positive BK polyomavirus (BKV) in situ hybridization (ISH), BKV real-time polymerase chain reaction (PCR) results of plasma and urine were negative. JCV ISH was performed and was found to be positive. JCV real-time PCR on urine, plasma, and the kidney biopsy tissue was positive. Reduction in immunosuppression resulted in resolution of JCV viremia. This case highlights that JC-PyVAN is a distinct clinical entity and is likely to have a better clinical outcome than BK-PyVAN. Concurrent infection with BKV and JCV may occur, but may be difficult to confirm due to the potential for cross-reactivity between BKV and JCV ISH stains.
Design of double-slotted high-Q photonic crystal nanocavity filled with electro-optic polymer (2016)

Compact thermosyphon using refrigerant flow control (1999)

In a compact closed two-phase thermosyphon which consists of a multitube radiator and a refrigerant bath, it is observed that the heat radiation performance drops as the refrigerant bath becomes thin. We have found that this is due to vapor–liquid interaction and dryness in the upper side of the boiling area. We have also improved that heat radiation performance with a new refrigerant flow controller. ©1999 Scripta Technica, Heat Trans Asian Res, 28(8): 627–639, 1999

Synthetic models for infrared reflectance signatures of micro-particle traces on surfaces (2019)

Machine learning based perception algorithms are increasingly being used for the development of autonomous navigation systems of self-driving vehicles. These vehicles are mainly designed to operate on structured roads or lanes and the ML algorithms are primarily used for functionalities such as object tracking, lane detection and semantic understanding. On the other hand, Autonomous/ Unmanned Ground Vehicles (UGV) being developed for military applications need to operate in unstructured, combat environment including diverse off-road terrain, inclement weather conditions, water hazards, GPS denied environment, smoke etc. Therefore, the perception algorithm requirements are different and have to be robust enough to account for several diverse terrain conditions and degradations in visual environment. In this paper, we present military-relevant requirements and challenges for scene perception that are not met by current state-of-the-art algorithms, and discuss potential strategies to address these capability gaps. We also present a survey of ML algorithms and datasets that could be employed to support maneuver of autonomous systems in complex terrains, focusing on techniques for (1) distributed scene perception using heterogeneous platforms, (2) computation in resource constrained environment (3) object detection in degraded visual imagery.

32-nm SOI programmable, high-bandwidth 8.0-GHz digital PLL (2011)

A digital phase-locked loop (PLL) to filter clock jitter in source-synchronous serial link applications is presented. The PLL achieves bandwidth programmability from 20 to 300 MHz while allowing for a maximum input frequency of 4 GHz. An improved resolution bang-bang phase detector and a double-regulated, supply-insensitive VCO mitigate extreme noise environments. The PLL is designed in 32-nm SOI technology and operates on 1.2-volt nominal supply, consuming 20 mW power.
Consequence-Driven Cybersecurity for High-Power Electric Vehicle Charging Infrastructure (2023)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;Cybersecurity of high-power charging infrastructure for electric vehicles (EVs) is critical to the safety, reliability, and consumer confidence in this publicly accessible technology. Cybersecurity vulnerabilities in high-power EV charging infrastructure may also present risks to broader transportation and energy-infrastructure systems. This paper details a methodology used to analyze and prioritize high-consequence events that could result from cybersecurity sabotage to high-power charging infrastructure. The highest prioritized events are evaluated under laboratory conditions for the severity of impact and the complexity of cybersecurity manipulation. Mitigation solutions and strategies are presented to secure the vulnerabilities that potentially lead to high-consequence events. These mitigations can be immediately implemented by industry or executed during the design stage.&lt;/div&gt;&lt;/div&gt;
On Bursian and Pierce Instabilities of Electron Beams Propagating in Weakly Irregular Channels (2007)

Summary form only given. The stability of stationary states of dense electron beams propagating in weakly irregular channels, in particular, in channels with non-deep periodically corrugated walls, is investigated using the method of coupled waves. We show that Bursian's instability can develop, leading to the formation of virtual cathodes or their disruption. In unlimited channels, separate zones of absolute and convective instabilities on the omega-k plane (Brillouin's diagram) are possible. In a channel of finite length, these zones are merged forming the well-known Bursian's instability in a vacuum channel or Pierce's instability when a space charge of electrons is neutralized by immobile ions. In addition, we investigate the influences of limited conductivity of channel walls, joined elements and other irregularities.

Moving Generic Associated Channel (G-ACh) IANA Registries to a New Registry (2014)

RFC 5586 generalized the applicability of the pseudowire Associated
Channel Header (PW-ACH) into the Associated Channel G-ACh.
However, registries and allocations of G-ACh parameters had been
distributed throughout different, sometimes unrelated, registries.
This document coalesces these into a new Generic Associated Channel
(G-ACh) Parameters registry under the Multiprotocol Label Switching
Architecture (MPLS) heading. This document updates RFC 5586. This
document also updates RFCs 6374, 6378, 6427, and 6428.
