A 0.7‐dB NF, +8.2‐dBm IIP3 CMOS low noise amplifier using frequency selective feedback
Authors: Jin Tae Hwan , Han Hong Gul , Kim Tae Wook 
Published: January 2015

SummaryA CMOS amplifier employing the frequency selective feedback technique using a shunt feedback capacitor is designed and measured. The proposed amplifier can achieve a high IIP3 (input referred third‐order intercept point) by reducing the third‐ and second‐order nonlinearity contributions to the IMD3 (third‐order intermodulation distortion), which is accomplished using a capacitor as the frequency selective element. Also, the shunt feedback capacitor improves the noise performance of the amplifier. By applying the technique to a cascode LNA using 0.18‐µm CMOS technology, we obtain the NF of 0.7 dB, an IIP3 of +8.2 dBm, and a gain of 15.1 dB at 14.4 mW of power consumption at 900 MHz.

Published: January 2015

ABSTRACTObjectiveDeficits in executive function (EF)—including inhibitory control, cognitive flexibility, decision‐making, and working memory—may be risk or maintenance factors for binge eating disorder (BED). However, there is mixed evidence regarding EF deficits in individuals with BED. Significant methodological weaknesses (e.g., use of a single EF measure, omission of relevant covariates) in the current literature represent one reason for lack of consensus.MethodThis study compared EF in a sample of overweight women with (n = 31) and without (n = 43) full or subthreshold BED, with the aim of conducting a multifaceted investigation of the neurocognitive profile of BED. A neuropsychological battery of EF was administered to all participants.ResultsAfter controlling for IQ and age, individuals with binge eating displayed significantly poorer performance on tasks of problem‐solving and inhibitory control, and displayed higher prioritization of immediate versus delayed rewards, but the two groups did not appear to differ on set‐shifting, working memory, and risk taking. Differences in inhibitory control were no longer statistically significant when depressive symptomology was added as a covariate and correction for multiple comparisons was applied. Exploratory analyses indicated that full and sub‐threshold BED groups did not differ in EF.DiscussionResults partially support the hypothesis of relative EF deficits in individuals with BED, suggesting that binge eating may be maintained by cognitive factors distinct from those of obesity. Future research should aim to replicate with a larger sample, control for a wider range of psychiatric comorbidities, and examine whether EF deficits predict treatment outcome. © 2014 Wiley Periodicals, Inc.

Photochromism of Acetyl‐Cyclophanochromene: Intriguing Stabilization of Photogenerated Colored o‐Quinonoid Intermediates
Authors: Mandal Susovan , Mukhopadhyay Arindam , Moorthy Jarugu Narasimha 
Published: January 2015

AbstractThe photochromism of a chromene annulated on [2.2]paracyclophane, Ac‐CPC, was investigated. Whereas the parent chromene 2,2‐diphenylbenzopyran shows photoinduced coloration only at very low temperatures, acetyl‐cyclophanochromene Ac‐CPC was found to exhibit room‐temperature photochromism. With no extended conjugation due to absence of any substituents in two cofacially‐oriented aryl rings, the through‐space delocalization of π‐electrons, i.e., the phane effect, manifests nicely leading to the stabilization of the photogenerated colored o‐quinonoid intermediates. The interaction between cofacial aryl rings is supported by the distance between them, as revealed by X‐ray crystal structure analysis. Additionally, electrophile···nucleophile interactions are surmised to be important for intriguingly longer persistence of the photogenerated intermediates of Ac‐CPC relative to the lifetime of the photogenerated intermediate generated from the parent cyclophanochromene, which is devoid of an electron‐withdrawing acetyl group.
Iodine‐Promoted Oxidative Amidation of Terminal Alkenes – Synthesis of α‐Ketoamides, Benzothiazoles, and Quinazolines
Authors: Deshidi Ramesh , Devari Shekaraiah , Shah Bhahwal Ali 
Published: January 2015

AbstractA novel metal‐free strategy for oxidative amidation of terminal alkenes by using I2/DMSO for the synthesis of α‐ketoamides has been developed. Intriguingly, the use of tert‐butylhydroperoxide (TBHP) as co‐oxidant can facilitate the synthesis of α‐ketoamides at room temperature without any solvent, thereby making it a green protocol. The reaction with primary amines can be easily achieved by using SeO2 as an oxidizing agent. Besides, the scope of the method was also extended to the synthesis of benzothiazolines and quinazolines.
Process oriented use of geostatistics to analyse creeping para‐glacial features
Authors: Bardou Eric , Favre‐Bulle Guillaume , Faucheux Claire , Jeannée Nicolas , Ornstein Pascal 
Published: January 2015

AbstractComplex para‐glacial systems may show signs of destabilization leading to frequent and potentially hazardous debris‐flows. Understanding creeping permafrost displacement over a period of time is therefore crucial for hazard management and risks assessment. This paper presents our methodology for estimating creeping permafrost displacement based upon data derived from various survey methods and demonstrates its relevance on the Glacier Bonnard system in southern Switzerland. Geostatistical processing allowed estimation of the displacement intensity over the area of interest, as well as assessment of the interpolation quality. Although the local measurement network needs to be refined, the results largely improve the understanding of the Bonnard para‐glacial system, though highlighting the need to locally refine the measurement network. In the present case, the destabilized front advances at ~1 m/a and the upstream creeping part at ~0.4 m/a. Variance analysis also provide objective thresholds that could be used to distinguish underlying physical processes. Copyright © 2015 John Wiley & Sons, Ltd.
Estimating the aroma glycosides in flue‐cured tobacco by solid‐phase extraction and gas chromatography–mass spectrometry: changes in the bound aroma profile during leaf maturity

Published: January 2015

AbstractGlycosidically bound aroma compounds in flue‐cured tobacco were estimated by capillary gas chromatography–mass spectrometry (GC–MS). After a fast isolation of extracts obtained by HP‐20 solid‐phase extraction and methanol elution, glycosides were treated with enzymatic hydrolysis and trifluoroacetylation (TFA) before GC–MS analysis. A totall of 21 bound aglycones, mainly consisting of aliphatic alcohol, aromatic components, C13‐norisoprenoids, sesquiterpenoids and polyphenols, were identified by enzymatic hydrolysis. In addition, with the aid of enzymatic hydrolysis, 14 glucosides, one rutinoside and three vicianosides were identified by TFA derivatization. The three vicianosides were identified for the first time in flue‐cured tobacco. The norisoprenoids group made up >40% of the total level of aglycons in ripe tobacco, followed by polyphenol and aromatic derivatives (27 and 19%, respectively). Generally, levels of bound compounds increased significantly and the content of total glycosides increased by 36% with maturation. Among the glycosides detected, 3‐oxo‐α‐ionol‐glucoside was the most sensitive to maturity and increased the maximum degree. Copyright © 2015 John Wiley & Sons, Ltd.

Published: January 2015

ABSTRACTThis study focuses on the function of NSSR1, a splicing factor, in neuronal injury in the ischemic mouse brain using the transient global cerebral ischemic mouse model and the cultured cells treated with oxygen‐glucose deprivation (OGD). The results showed that the cerebral ischemia triggers the expression of NSSR1 in hippocampal astrocytes, predominantly the dephosphorylated NSSR1 proteins, and the Exon3 inclusive NCAM‐L1 variant and the Exon4 inclusive CREB variant. While in the hippocampus of astrocyte‐specific NSSR1 conditional knockdown (cKD) mice, where cerebral ischemia no longer triggers NSSR1 expression in astrocytes, the expression of Exon3 inclusive NCAM‐L1 variant and Exon4 inclusive CREB variant were no longer triggered as well. In addition, the injury of hippocampal neurons was more severe in astrocyte‐specific NSSR1 cKD mice compared with in wild‐type mice after brain ischemia. Of note, the culture media harvested from the astrocytes with overexpression of NSSR1 or the Exon3 inclusive NCAM‐L1 variant, or Exon4 inclusive CREB variant were all able to reduce the neuronal injury induced by OGD. The results provide the evidence demonstrating that: (1) Splicing factor NSSR1 is a new factor involved in reducing ischemic injury. (2) Ischemia induces NSSR1 expression in astrocytes, not in neurons. (3) NSSR1‐mediated pathway in astrocytes is required for reducing ischemic neuronal injury. (4) NCAM‐L1 and CREB are probably mediators in NSSR1‐mediated pathway. In conclusion, our results suggest for the first time that NSSR1 may provide a novel mechanism for reducing neuronal injury after ischemia, probably through regulation on alternative splicing of NCAM‐L1 and CREB in astrocytes.

AbstractGrowing efforts in the study of digital literacies push for continued (re)shaping of policy and pedagogical interventions. In this column, we take up concerns in participatory cultures to revisit a longstanding issue pertaining to language. Evident in the literature on digital literacies is an implicit treatment of language, particularly around whose languages are included. In our respective research, we are challenged by questions that seek to identify literacies and languages as repertoires of practice in youth's lives. We want to know, if youth are communicating and engaging each other across media platforms, what languages or linguistic forms are leveraged in their lives? In what ways are youth supported socially and educationally? We come together here to make language more explicit in the conversation.

Published: January 2015

AbstractFunctioning pancreaticoduodenal neuroendocrine tumors (PD‐NETs) are popular in a textbook, but they are still unfamiliar to a general clinician, and delay of diagnosis or misdiagnosis has been reported even today. It is a consensus that sporadic functioning PD‐NET is cured only by surgical resection. So, early detection and early resection is the gold standard for the treatment of functioning PD‐NET. Functioning PD‐NETs in patients with multiple endocrine neoplasia type 1 (MEN 1) are often multiple. You should check about MEN 1 whenever you encountered multiple PD‐NET. They are diagnosed in younger age than sporadic cases. In most cases they are accompanied with numerous microscopic or macroscopic nonfunctioning P‐NETs, which are potentially metastatic and the most common cause of death in MEN 1 patients. © Japanese Society of Hepato‐Biliary‐Pancreatic Surgery
Using multi‐timescale methods and satellite‐derived land surface temperature for the interpolation of daily maximum air temperature in Oregon

ABSTRACTThere is a growing demand for fine‐grained (e.g. 1 km) daily historical meteorological data. Traditional approaches interpolate between observations collected at existing meteorological stations; however, the demand for ever increasing fine resolutions has begun to outstrip the available ground‐station data, especially for daily timescales. One promising technique known as the climate‐aided interpolation (CAI) has the advantage of incorporating climatological data to improve fine‐grained spatial detail while still producing a daily product. By estimating spatial structure at a coarser timescale than the target timescale, more ground‐station data can be used, leading to improved accuracy in these multi‐timescale procedures. Another approach to improve fine‐grained spatial structure is the incorporation of additional environmental covariates that are measured at fine grains. Elevation has long been used in this role, but other covariates, especially remotely sensed measures of land cover and land surface temperatures (LST), are also promising. In this paper, we provide a comprehensive evaluation of three interpolation methods and rigorous evaluation of multi‐timescale procedures that do and do not include additional environmental covariates includingLST. We perform this evaluation on daily maximum air temperature predictions using a region with widely varying climates, the state of Oregon,USA. We find that multi‐timescale procedures provide a roughly 10% improvement in prediction accuracy over single‐timescale procedures. For multi‐timescale approaches, we find that universal kriging has the lowest root mean square error (RMSE) but has a lower predictive accuracy when the number of station decreases in the study area. Thus, generalized additive models (GAM) and geographically weighted regression (GWR) may be superior interpolation methods in areas with sparse station data. Most covariates other than elevation do not improve accuracy, butLSTmay be useful during summer when elevation displays low correlation withTmax. Analyses also show that elevation andLSTprovide increased spatial heterogeneity.

ABSTRACTAs the societal impacts of hazardous weather and other environmental pressures grow, the need for integrated predictions that can represent the numerous feedbacks and linkages between sub‐systems is greater than ever. This was well illustrated during winter 2013/2014 when a prolonged series of deep Atlantic depressions over a 3 month period resulted in damaging wind storms and exceptional rainfall accumulations. The impact on livelihoods and property from the resulting coastal surge and river and surface flooding was substantial. This study reviews the observational and modelling toolkit available to operational meteorologists during this period, which focusses on precipitation forecasting months, weeks, days and hours ahead of time. The routine availability of high‐resolution (km scale) deterministic and ensemble rainfall predictions for short‐range weather forecasting as well as weather‐resolving seasonal prediction capability represent notable landmarks that have resulted from significant progress in research and development over the past decade. Latest results demonstrated that the suite of global and high‐resolution UK numerical weather prediction models provided excellent guidance during this period, supported by high‐resolution observations networks, such as weather radar, which proved resilient in difficult conditions. The specific challenges for demonstrating this performance for high‐resolution precipitation forecasts are discussed. Despite their good operational performance, there remains a need to further develop the capability and skill of these tools to fully meet user needs and to increase the value that they deliver. These challenges are discussed, notably to accelerate the progress towards understanding the value that might be delivered through more integrated environmental prediction.

Published: January 2015

ScopeAcute kidney injury (AKI) is the most frequent and serious complication in sepsis, a potentially deadly inflammatory response induced by bacterial, viral, or fungal infection. LPS‐induced AKI is associated with an abnormal inflammatory response, including renal endothelial dysfunction and renal inflammation. Resveratrol, a natural phytoalexin with low toxicity and anti‐inflammatory properties, is known to protect endothelial cells and modulate the immune response in sepsis.Methods and resultsThis study investigates the potential protective effects of resveratrol on AKI induced by LPS exposure of mice. Resveratrol was administered as a pre‐ and posttreatment, or as a posttreatment alone following LPS injection and compared to control groups. Resveratrol significantly improved kidney function and lowered serum and kidney tissue inflammatory cytokine levels. Consistently, resveratrol prevented endotoxin‐induced disruption of endothelial cell permeability and inhibited inflammation of kidney tissue. Resveratrol treatment attenuated the effects of LPS on macrophages, with significant inhibition of activation, cytokine release, and Toll‐like receptor 4 activation. Resveratrol treatment also resulted in decreased expression of iNOS, Bcl‐2, and Bcl‐xL in macrophages, which was linked with induction of apoptosis in macrophages.ConclusionOur studies suggest that resveratrol might represent a novel therapeutic agent to prevent and treat sepsis‐induced AKI.

AbstractBackgroundOtitis media with effusion is a worldwide ear disease. The current treatment is to surgically insert a ventilation grommet into the tympanic membrane. A robotic device allowing automatic grommet insertion has been designed in a previous study; however, the part of the membrane where the malleus bone is attached to the inner surface is to be avoided during the insertion process.MethodsThis paper proposes a synergy of optical flow technique and a gradient vector flow active contours algorithm to achieve an online tracking of the malleus under endoscopic vision, to guide the working channel to move efficiently during the surgery.ResultsThe proposed method shows a more stable and accurate tracking performance than the current tracking methods in preclinical tests.ConclusionWith satisfactory tracking results, vision guidance of a suitable insertion spot can be provided to the device to perform the surgery in an automatic way.

Published: January 2015

AbstractBackgroundThis work evaluated the accuracy and safety of a protocol for minimally‐invasive flapless zygomatic implant placement that uses computer‐guided stereolithographic mucosa‐supported surgical templates.MethodsA total of six zygomatic implants were placed in three formalin‐fixed human cadaver heads, with edentulous and severely atrophic posterior maxillae. CT scans of each cadaver head were performed after zygomatic implant placement, to evaluate the lateral error (LE) at implant tip and base, and the angular error (AE) of the implant body.ResultsExcluding the implant placed outside the drilling channel, the LE at the implant base was less than 1 mm in all cases. The average LE at the tip was 3.86 mm, and the AE was less than 6° in all cases, with an average of 4.5°.ConclusionComputer‐guided minimally‐invasive flapless zygomatic implant surgery remains challenging. Careful planning and perfect stability of the surgical guide are essential. Copyright © 2015 John Wiley & Sons, Ltd.
Electrostatic Interaction and Reaction Behavior of a 1, 2,4‐Triazole Mixture with Dinitrobenzene

Published: January 2015

AbstractThe electrostatic interactions between gas generating agent and organic electron withdrawing additives were studied to understand how the interaction affects the reactions of their thermal behavior. To explore the electronic interaction and its effect, the thermal behavior of a mixture of dinitrobenzene isomers [p‐dinitrobenzene (pDNB) and m‐dinitrobenzene (mDNB)] and 1, 2,4‐triazole (TA) was analyzed. Density functional calculations and electron density analysis proved that both pDNB and mDNB in a 1:1 ratio withdraw electrons from TA. The analysis of pyrolysis behavior showed that TA and dinitrobenzene mixtures (TA/pDNB or TA/mDNB) react at lower temperatures than each precursor. Gas chromatography mass analysis and UV/Vis spectroscopy showed reasonable results that suggested that pDNB and TA make condensed products in the initial stage of the reaction according to the differential scanning calorimetry measurement. When the mixtures were ignited under pressurized conditions, TA/pDNB burned easily while TA/mDNB burned only partially. These results suggested that the interaction between triazole and dinitrobenzene affects the pyrolysis and combustion behavior of a TA/dinitrobenzene mixture.
