ABSTRACTThe current method of measuring arthrofibrosis in live rabbits is critically limited. Specifically, this method involves radioactive fluoroscopy, error‐prone goniometric measurements, and static joint angle outcomes that fail to approximate the compliance of tissues surrounding the joint. This study aims to validate a novel method of capturing the compliance of contracted tissues surrounding the joint without the use of fluoroscopy or animal sacrifice. Surgically induced contractures of one‐hundred and eight rabbits were measured using the current standard of contracture measurement (a pulley system) as well as a newly designed dynamic load cell (DLC) device. The DLC device was highly reliable when compared to the pulley system (r = 0.907, p < 0.001). Finally, the DLC device produced joint stiffness hysteresis curves capable of approximating the compliance of stiff joint tissues, ultimately calculating a mean joint stiffness of 1.57 ± 1.31 N · m · rad−1 (range, 0.33–6.37 N · m · rad−1). In conclusion, the DLC device represents a valid method for measuring joint contractures. Further, the DLC device notably improves current techniques by introducing the capacity to approximate the compliance of contracted tissues in living rabbits. © 2018 Orthopaedic Research Society.

Regional and intra‐annual stability of dissolved organic matter composition and biolability in high‐latitude Alaskan rivers
Authors: Mutschlecner Audrey E. , Guerard Jennifer J. , Jones Jeremy B. , Harms Tamara K. 
Published: February 2018

AbstractNutrient availability and molecular composition of dissolved organic matter (DOM) determine whether the carbon (C) associated with DOM is respired during decomposition or exported from stream networks. High‐latitude ecosystems are changing rapidly due to permafrost thaw, shifts in vegetation, and increasing runoff, which alter sources of DOM and nutrients to rivers. To address how changes in the composition of riverine DOM and nutrients may influence C cycling, we quantified biolability of DOM across a latitudinal gradient in Alaska and assessed temporal patterns associated with intra‐annual variation in hydrology. We measured biolability under ambient and fertilized conditions and characterized optical and chemical properties of DOM to determine the relative influence of nutrients and molecular composition of DOM on its fate in rivers. Biolability was low, comprising 4% of the DOM pool on average and 0–42% across all sites and seasons. Optical indicators of the molecular composition of the DOM pool were more constant in space and time than bulk concentrations of dissolved C and nutrients, and described a DOM pool dominated by humic‐like functional groups. Phosphorus limited biolability at freshet, but biolability was not linked to DOM composition. Strong hydrologic connection of high‐latitude rivers to a large pool of soil organic matter likely results in export of recalcitrant DOM to receiving rivers and coasts in this region, contributing to stability of the high‐latitude C cycle. However, increased inputs of phosphorus or DOM of greater biolability will likely cause increased respiration of riverine DOM and flux of CO2 to the atmosphere.
Tribological evaluation of calcium‐copper‐titanate/cerium oxide‐based nanolubricants in sliding contact
Authors: Gupta Rajeev Nayan , Harsha A.P. 
Published: February 2018

AbstractIn the present work, calcium‐copper‐titanate (≈85 nm) and cerium oxide (≈90 nm) nanoparticles were blended in paraffin oil (PO) as an additive by varying the concentration from 0.1 to 1.0% w/v, and tribo‐performance was evaluated with four‐ball tester. The concentration 0.25% w/v of the nanoparticles in PO was found to be optimum in antiwear and antifriction property tests for both types of nanolubricants. At this particular concentration, the maximum reductions in the wear scar diameter were 38.4 and 26.1% for calcium‐copper‐titanate and cerium oxide‐based nanolubricants, respectively. Also, the mean coefficient of friction was reduced by 17.3 and 29.6% at this optimum concentration for both types of lubricants. For extreme‐pressure test, the load‐carrying capacity of the nanolubricants was improved from 126 to 160 kgf as compared with base PO. The worn surfaces were examined with scanning electron microscope, energy‐dispersive spectroscopy, and atomic force microscope to study the physical phenomena that occurred during the sliding.

Published: February 2018

PurposeTo develop an automatic deep feature classification (DFC) method for distinguishing benign angiomyolipoma without visible fat (AMLwvf) from malignant clear cell renal cell carcinoma (ccRCC) from abdominal contrast‐enhanced computer tomography (CE CT) images.MethodsA dataset including 80 abdominal CT images of 39 AMLwvf and 41 ccRCC patients was used. We proposed a DFC method for differentiating the small renal masses (SRM) into AMLwvf and ccRCC using the combination of hand‐crafted and deep features, and machine learning classifiers. First, 71‐dimensional hand‐crafted features (HCF) of texture and shape were extracted from the SRM contours. Second, 1000–4000‐dimensional deep features (DF) were extracted from the ImageNet pretrained deep learning model with the SRM image patches. In DF extraction, we proposed the texture image patches (TIP) to emphasize the texture information inside the mass in DFs and reduce the mass size variability. Finally, the two features were concatenated and the random forest (RF) classifier was trained on these concatenated features to classify the types of SRMs. The proposed method was tested on our dataset using leave‐one‐out cross‐validation and evaluated using accuracy, sensitivity, specificity, positive predictive values (PPV), negative predictive values (NPV), and area under receiver operating characteristics curve (AUC). In experiments, the combinations of four deep learning models, AlexNet, VGGNet, GoogleNet, and ResNet, and four input image patches, including original, masked, mass‐size, and texture image patches, were compared and analyzed.ResultsIn qualitative evaluation, we observed the change in feature distributions between the proposed and comparative methods using tSNE method. In quantitative evaluation, we evaluated and compared the classification results, and observed that (a) the proposed HCF + DF outperformed HCF‐only and DF‐only, (b) AlexNet showed generally the best performances among the CNN models, and (c) the proposed TIPs not only achieved the competitive performances among the input patches, but also steady performance regardless of CNN models. As a result, the proposed method achieved the accuracy of 76.6 ± 1.4% for the proposed HCF + DF with AlexNet and TIPs, which improved the accuracy by 6.6%p and 8.3%p compared to HCF‐only and DF‐only, respectively.ConclusionsThe proposed shape features and TIPs improved the HCFs and DFs, respectively, and the feature concatenation further enhanced the quality of features for differentiating AMLwvf from ccRCC in abdominal CE CT images.

Published: February 2018

PurposeTo assess RF‐induced heating during MRI of patients with implanted stereo‐electroencephalography electrodes.MethodsSimulations and experimental measurements using phantom and a head‐only transmit/receive coil on a 3T MR system were performed to evaluate temperature increases at the tip of an 8‐contact stereo‐electroencephalography electrode and an insulated wire partially immersed into the phantom. The lengths of wire producing maximum (resonant condition) and minimum (anti‐resonant condition) heating were evaluated for different entry modes and penetration depths.ResultsFor both wire and stereo‐electroencephalography electrode, resonant lengths were close to odd integral multiples of RF quarter wavelength in air and antiresonant length close to even integral multiples of RF quarter wavelength, both being unaffected by the entry mode. In the resonant condition, temperature increased by as much as a factor of 10 higher than that at antiresonant condition. Larger penetration depths did not change resonant length, but did lead to increased RF heating.ConclusionFor the partially immersed implants like stereo‐electroencephalography electrode, the resonant lengths were found to be independent of the penetration depths and entry modes, although the temperature increases may vary. Avoiding such lengths of cables can reduce the risk of tissue heating during in vivo MRI.

AbstractIn exploring the role of increased ligand basicity as well as denticity on moving from ethylenediamine (en) or 1,3‐diaminopropane (1,3‐dap), on supramolecular solid formation, complexation involving diethylenetriamine (det) and azide with CoII and CuII afforded three new complexes [Co(det)2](N3)3 (1), [Co(det)(N3)3] (2) and [Cu2(det)2(N3)5(H2O)2Na] (3) under self assembling conditions and are characterized structurally and magnetically. Formation of 1 and 2 is sensitive to temperature of crystallization, while such a temperature influence could not be observed for CuII system due to lack of crystals at low temperatures. As expected with a tridentate ligand, strong chelation stabilizes 1 at LT and is a thermodynamically stable product, while isolation of 2 at RT conditions is under kinetic control. Decomposition of 2 at high temperatures (above 70 °C) as revealed through temperature dependent UV‐vis spectral studies also confirms its instability. Presence of three donor sites of det, leads to interesting structural pattern in Jahn‐Teller active CuII, resulting in cationic chains of [Cu(det)(N3)]n+ bridged by μ‐1,3 azido bridges to the neighboring [Na(H2O)2(N3)2]− units, thus leading to a 2‐D assembly of alternating layers of cationic and anionic chains in the unit cell of 3. Magnetic studies of 3 reveals anti‐ferromagnetic interaction between the copper ions (J=– 0.479 cm–1), in conformity with the bridge angle dependent magnetic behavior in azido bridged copper complexes.

Published: February 2018

AbstractWe synthesized noria‐containing cross‐linking materials, Cross(Noria‐MA‐co‐DM[n]m), by radical polymerization of a noria derivative with pendant methacryloyl groups (noria‐MA) and α, ω‐alkanedimethacrylamides (DM[n], n=3, 6, 12) at feed ratios of noria‐MA/DM[n]=1/2.4, 1/12, and 1/24 (m=2.4, 12. and 24). Alkaline hydrolysis reaction of Cross(Noria‐MA‐co‐DM[n]m) removed the noria moieties to give corresponding cross‐linking materials, Cross‐COOH‐DM[n]m, containing noria‐templated fixed cavities with pendant carboxylic acid groups. Among the noria‐containing cross‐linking materials, Cross(Noria‐MA‐co‐DM[6]24) showed the greatest extent of removal of noria upon hydrolysis. Nitrogen and carbon dioxide absorption studies indicated that Cross(Noria‐MA‐co‐DM[6]24) contains fixed cavities, whereas Cross‐COOH‐DM[6]24 does not in the solid (unswollen) state. Examination of the inclusion‐complex‐forming ability of the synthesized cross‐linking materials using aqueous solutions of metal ions revealed that Cross‐COOH‐DM[6]24 has the greatest absorption capacity. These results indicate that Cross‐COOH‐DM[6]24 indeed contains noria‐templated cavities that can accommodate metal ions in aqueous solution.

Published: February 2018

AbstractNanofibers/nanowires usually exhibit exceptionally low flexural rigidities and remarkable tolerance against mechanical bending, showing superior advantages in flexible electronics applications. Electrospinning is regarded as a powerful process for this 1D nanostructure; however, it can only be able to produce chaotic fibers that are incompatible with the well‐patterned microstructures in flexible electronics. Electro‐hydrodynamic (EHD) direct‐writing technology enables large‐scale deposition of highly aligned nanofibers in an additive, noncontact, real‐time adjustment, and individual control manner on rigid or flexible, planar or curved substrates, making it rather attractive in the fabrication of flexible electronics. In this Review, the ground‐breaking research progress in the field of EHD direct‐writing technology is summarized, including a brief chronology of EHD direct‐writing techniques, basic principles and alignment strategies, and applications in flexible electronics. Finally, future prospects are suggested to advance flexible electronics based on orderly arranged EHD direct‐written fibers. This technology overcomes the limitations of the resolution of fabrication and viscosity of ink of conventional inkjet printing, and represents major advances in manufacturing of flexible electronics.

Published: February 2018

AbstractPhotodetection in the short‐wave infrared (SWIR) spectrum is a challenging task achieved often by costly low bandgap compound semiconductors involving highly toxic elements. In this work, an alternative low‐cost approach is reported for SWIR sensors that rely on the plasmonic‐induced photothermal effect of solution‐processed colloidal gold nanorods (Au NRs). A series of uniform solution‐processed Au NRs of various aspect ratios are prepared exhibiting a strong and well‐defined longitudinal localized surface plasmon resonance (L‐LSPR) maximum from 900 nm to 1.3 µm. A hybrid device structure is fabricated by applying Au NRs on the surface of a thermistor. Under a monochromatic illumination, hybrid Au‐NR/thermistor devices exhibit a clear photoresponse in the form of photoinduced resistance drop in the wavelength window from 1.0 to 1.8 µm. The photoresponsivity of such hybrid devices reaches a maximum value of 4.44 × 107 Ω W−1 at λ = 1.4 µm (intensity = 0.28 mW cm−2), a wavelength in agreement with the L‐LSPR of the Au NRs applied. Colloidal Au NRs, capable to perform fast conversion between photon absorption and thermal energy, thus open an interesting avenue for alternative low‐cost SWIR photodetection.

AbstractThis article addresses the relationships between agile development and entrepreneurship. The objective of the study is to verify that the adoption of agile practices can promote entrepreneurial skills in software developers. In this study, agile practices were related to entrepreneurial skills, and developers of the software industry and academia professors were invited to contribute. Questionnaires were sent to the participants to obtain their opinion regarding this research. Participants also opined about the possibility of entrepreneurial skills being an observable behavior in agile culture, ie, if they are visible artifacts of agile culture. As a result, the study found a set of agile practices that promote entrepreneurial skills in software developers. That is, it was found that agile practices promote entrepreneurial behavior in these professionals. These entrepreneurial skills are sustained by the same basic values and assumptions that were learned by developers to resolve internal integration and external adaptation issues during the adoption of agile practices. In this article, an integration model has been adapted from other areas, thereby opening a new field of study involving the relationships between academic research and professional practice on entrepreneurship in the software area and agile development.
Automatic benchmark profiling through advanced workflow‐based trace analysis
Authors: Martin Alexis , Marangozova‐Martin Vania 
Published: February 2018

SummaryBenchmarking has proven to be crucial for the investigation of the behavior and performances of a system. However, the choice of relevant benchmarks still remains a challenge. To help the process of comparing and choosing among benchmarks, we propose a solution for automatic benchmark profiling. It computes unified benchmark profiles reflecting benchmarks' duration, function repartition, stability, CPU efficiency, parallelization, and memory usage. Our approach identifies the needed system information for profile computation and collects it from execution traces captured without benchmark code modifications. It structures profile computation as a reproducible workflow for automatic trace analysis, which efficiently manages important trace volumes. In this paper, we report on the design and the implementation of our approach, which involves the collection and analysis of about 500 GB of trace data coming from 2 different platforms (an x86 desktop machine and the Juno SoC board). The computed benchmark profiles provide valuable insights about the benchmarks' behavior and help compare different benchmarks on the same platform as well as the behavior of the same benchmark on different platforms.

Published: February 2018

AbstractSupported bimetallic catalysts have been studied because of their enhanced catalytic properties due to metal‐metal interactions compared with monometallic catalysts. We focused on galvanic deposition (GD) as a bimetallization method, which achieves well‐defined metal‐metal interfaces by exchanging heterogeneous metals with different ionisation tendencies. We have developed Ni@Ag/SiO2 catalysts for CO oxidation, Co@Ru/Al2O3 catalysts for automotive three‐way reactions and Pd−Co/Al2O3 catalysts for methane combustion by using the GD method. In all cases, the catalysts prepared by the GD method showed higher catalytic activity than the corresponding monometallic and bimetallic catalysts prepared by the conventional co‐impregnation method. The GD method provides contact between noble and base metals to improve the electronic state, surface structure and reducibility of noble metals.
The Power of the Progress Conference
Authors: Macken Carol 
Published: February 2018

AbstractMotivating reluctant readers has been always been a challenge. The author designed a conference structure in which explicit evidence of the student's progress is presented. The structure includes a review by the teacher of the student's prior reading level and documentation of the student's current skills. A conference with the student follows in which the teacher shares the texts from the student's previous reading level and current level. The teacher and student compare the features of the two texts, and the teacher names the specific reading strategies that the student is successfully employing. The teacher leads the student to an articulation of the positive steps that he or she has taken to improve. Finally, the instructor offers a teaching point for continued progress, which is undergirded by the positive context of the conference.
Image‐guided surgery in cancer: A strategy to reduce incidence of positive surgical margins
Authors: Tringale Kathryn R. , Pang John , Nguyen Quyen T. 
Published: February 2018

Primary treatment for many solid cancers includes surgical excision or radiation therapy, with or without the use of adjuvant therapy. This can include the addition of radiation and chemotherapy after primary surgical therapy, or the addition of chemotherapy and salvage surgery to primary radiation therapy. Both primary therapies, surgery and radiation, require precise anatomic localization of tumor. If tumor is not targeted adequately with initial treatment, disease recurrence may ensue, and if targeting is too broad, unnecessary morbidity may occur to nearby structures or remaining normal tissue. Fluorescence imaging using intraoperative contrast agents is a rapidly growing field for improving visualization in cancer surgery to facilitate resection in order to obtain negative margins. There are multiple strategies for tumor visualization based on antibodies against surface markers or ligands for receptors preferentially expressed in cancer. In this article, we review the incidence and clinical implications of positive surgical margins for some of the most common solid tumors. Within this context, we present the ongoing clinical and preclinical studies focused on the use of intraoperative contrast agents to improve surgical margins.This article is categorized under:
