Prosodic faithfulness to foot edges: the case of Turkish stress
Authors: Özçelik Öner
Published: September 2014

This paper presents a novel approach to capturing exceptional stress that relies on prespecification of foot edges in the input. Focusing on Turkish, this approach accounts for both regular and exceptional stress in a unified manner and within a single grammar, and unlike other approaches, does not overpredict. On this account, Turkish is a footless, but trochaic, language. Both regular and exceptional Turkish morphemes are subject to the same constraint ranking; exceptional morphemes are different only in that they have one or more syllables already footed in the input, although the type of foot (e.g. trochaicity, binarity) is determined by the constraints of the grammar. As regular morphemes vacuously satisfy these constraints (which act on the foot), trochees appear on the surface only if there is an input foot available (i.e. in words with exceptional morphemes), since the grammar itself has no apparatus to parse syllables into feet.
Differential susceptibility to effects of maternal sensitivity? A study of candidate plasticity genes
Authors: Belsky Jay , Newman Daniel A. , Widaman Keith F. , Rodkin Phil , Pluess Michael , Fraley R. Chris , Berry Daniel , Helm Jonathan L. , Roisman Glenn I.
Published: September 2014

Here we tested whether there was genetic moderation of effects of early maternal sensitivity on social–emotional and cognitive–linguistic development from early childhood onward and whether any detected Gene × Environment interaction effects proved consistent with differential-susceptibility or diathesis–stress models of Person × Environment interaction (N= 695). Two new approaches for evaluating models were employed with 12 candidate genes. Whereas maternal sensitivity proved to be a consistent predictor of child functioning across the primary-school years, candidate genes did not show many main effects, nor did they tend to interact with maternal sensitivity/insensitivity. These findings suggest that the developmental benefits of early sensitive mothering and the costs of insensitive mothering look more similar than different across genetically different children in the current sample. Although acknowledgement of this result is important, it is equally important that the generally null Gene × Environment results reported here not be overgeneralized to other samples, other predictors, other outcomes, and other candidate genes.
Cognitive Rehabilitation Multi-family Group Intervention for Individuals with Mild Cognitive Impairment and Their Care-Partners
Authors: Schmitter-Edgecombe Maureen , Dyck Dennis G.
Published: September 2014

There is increasing need for early, pro-active programs that can delay dementia diagnosis and enhance well-being of individuals with mild cognitive impairment (MCI) and their care-partners (i.e., care-dyads). This randomized controlled trial evaluated the efficacy of a combined cognitive rehabilitation and multi-family group treatment (CR-MFG) that was designed to facilitate adoption of newly learned cognitive strategies into the care-dyads everyday lives. Analyzed data included 23 care-dyads who participated in CR-MFG treatment and 23 care-dyads in standard care (SC). The 3-month intervention consisted of individual joining sessions, an educational workshop, and 20/twice weekly multifamily memory strategy training and problem-solving sessions. Everyday functioning, memory, and psychological functioning (i.e., quality-of-life, depression, coping) were assessed. The CR-MFG intervention was associated with significant post-test group differences and improved post-test performances by the MCI participants on performance-based measures of everyday functioning and neuropsychological tests of memory. There was also some suggestion that CR-MFG care-partners perceived positive change in the everyday functioning of the MCI participants. In contrast, no post-test group differences were found for either care-dyad member on the self-report psychological measures; care-partners in the treatment group did self-report improved coping behaviors at post-test. These 3-month results are preliminary but suggestive that CR-MFG may produce modest, practical everyday functional benefits for persons with MCI. (JINS, 2014, 20, 1–12)

Authors: Baingana Rhona K , Enyaru John K , Tjalsma Harold , Swinkels Dorine W , Davidsson Lena
Published: September 2014

Objective

To describe the aetiology of anaemia in pregnant Ugandan women and explore Fe deficiency and common infections as contributors to anaemia in this population.

Design

Cross-sectional study in which Hb, ferritin, transferrin receptor (sTfR), C-reactive protein, α-1 acid glycoprotein, hepcidin, malaria, hookworm infestation, syphilis andHelicobacter pyloriinfection were assessed.

Setting

Antenatal care clinic at Kawempe Health Centre, Kampala, Uganda.

Subjects

HIV-negative women (n151) in their first or second pregnancy at 10–16 weeks’ gestation.

Results

The prevalence of anaemia was 29·1 %. Fe deficiency was 40·4 % and 14·6 % based on ferritin <30 μg/l and on adjusted ferritin <12 μg/l respectively, and 6·6 % based on sTfR >8·3 μg/ml. The prevalence of Fe-deficiency anaemia was 9·3 % based on ferritin <30 μg/l, 6·6 % based on adjusted ferritin <12 μg/l and 4·3 % based on sTfR >8·3 μg/ml. Hepcidin concentration was positively correlated with ferritin concentration (n151,r=0·578,P<0·00001).H. pyloriinfection was highly prevalent (70 %) while malaria, hookworm infestation and syphilis were not common. Of all women, 60·3 % had α-1 acid glycoprotein >1 g/l and/or C-reactive protein >5 mg/l. Malaria parasitaemia (OR=6·85; 95 % CI 1·25, 37·41,P=0·026) and Fe deficiency defined using sTfR (OR=5·58; 95 % CI 1·26, 24·80,P=0·024) were independently and positively associated with anaemia. Population-attributable risk factors for anaemia for raised C-reactive protein, Fe deficiency defined by sTfR >8·3 μg/ml and presence of malaria parasites were 41·6 (95 % CI 11·1, 72·2) %, 13·5 (95 % CI 2·0, 25·0) % and 12·0 (95 % CI 1·4, 22·6) %, respectively.

Conclusions

Infections and inflammation are of greater significance than Fe deficiency in the aetiology of anaemia in pregnant Ugandan women during the first trimester.

Authors: Skreden Marianne , Bere Elling , Sagedal Linda R , Vistad Ingvild , Øverby Nina C
Published: September 2014

Objective

To describe changes in consumption of different types of beverages from pre-pregnancy to early pregnancy, and to examine associations with maternal age, educational level and BMI.

Design

Cross-sectional design. Participants answered an FFQ at inclusion into a randomized controlled trial, the Fit for Delivery (FFD) trial, in median gestational week 15 (range: 9–20), reporting current consumption and in retrospect how often they drank the different beverages pre-pregnancy.

Setting

Eight local antenatal clinics in southern Norway from September 2009 to February 2013.

Subjects

Five hundred and seventy-five healthy pregnant nulliparous women.

Results

Pre-pregnancy, 27 % reported drinking alcohol at least once weekly, compared with none in early pregnancy (P<0·001). The percentage of women drinking coffee (38 %v. 10 %,P<0·001), sugar-sweetened beverages (10 %v. 6 %,P=0·011) and artificially sweetened beverages (12 %v. 9 %,P=0·001) at least daily decreased significantly from pre-pregnancy to early pregnancy, while the percentage of women who reported to drink water (85 %v. 92 %,P<0·001), fruit juice (14 %v. 20 %,P=0·001) and milk (37 %v. 42 %,P=0·001) at least daily increased significantly. From pre-pregnancy to early pregnancy higher educated women reduced their consumption frequency of coffee significantly more than women with lower education. Older women reduced their consumption frequency of coffee and artificially sweetened beverages and increased their consumption frequency of fruit juice and milk significantly more than younger women.

Conclusions

There is a significant change in beverage consumption from pre-pregnancy to early pregnancy among Norwegian nulliparous women.
Body composition indices of a load–capacity model: gender- and BMI-specific reference curves
Authors: Siervo Mario , Prado Carla M , Mire Emily , Broyles Stephanie , Wells Jonathan CK , Heymsfield Steven , Katzmarzyk Peter T
Published: September 2014

Objective

Fat mass (FM) and fat-free mass (FFM) are frequently measured to define body composition phenotypes. The load–capacity model integrates the effects of both FM and FFM to improve disease-risk prediction. We aimed to derive age-, gender- and BMI-specific reference curves of load–capacity model indices in an adult population (≥18 years).

Design

Cross-sectional study. Dual-energy X-ray absorptiometry was used to measure FM, FFM, appendicular skeletal muscle mass (ASM) and truncal fat mass (TrFM). Two metabolic load–capacity indices were calculated: ratio of FM (kg) to FFM (kg) and ratio of TrFM (kg) to ASM (kg). Age-standardised reference curves, stratified by gender and BMI (<25·0 kg/m2, 25·0–29·9 kg/m2, ≥30·0 kg/m2), were constructed using an LMS approach. Percentiles of the reference curves were 5th, 15th, 25th, 50th, 75th, 85th and 95th.

Setting

Secondary analysis of data from the 1999–2004 National Health and Nutrition Examination Survey (NHANES).

Subjects

The population included 6580 females and 6656 males.

Results

The unweighted proportions of obesity in males and females were 25·5 % and 34·7 %, respectively. The average values of both FM:FFM and TrFM:ASM were greater in female and obese subjects. Gender and BMI influenced the shape of the association of age with FM:FFM and TrFM:ASM, as a curvilinear relationship was observed in female and obese subjects. Menopause appeared to modify the steepness of the reference curves of both indices.

Conclusions

This is a novel risk-stratification approach integrating the effects of high adiposity and low muscle mass which may be particularly useful to identify cases of sarcopenic obesity and improve disease-risk prediction.

Application of mass spectrometry enables the detection of metabolic differences between groups of related organisms. Differences in the metabolic fingerprints of wild-type Solanum lycopersicum and three monogenic mutants, ripening inhibitor (rin), non-ripening (nor) and Colourless non-ripening (Cnr), of tomato are captured with regard to ripening behaviour. A high-resolution tandem mass spectrometry system coupled to liquid chromatography produced a time series of the ripening behaviour at discrete intervals with a focus on changes post-anthesis. Internal standards and quality controls were used to ensure system stability. The raw data of the samples and reference compounds including study protocols have been deposited in the open metabolomics database MetaboLights via the metadata annotation tool Isatab to enable efficient re-use of the datasets, such as in metabolomics cross-study comparisons or data fusion exercises.

Published: September 2014

Mass spectrometry is the method of choice for deep and reliable exploration of the (human) proteome. Targeted mass spectrometry reliably detects and quantifies pre-determined sets of proteins in a complex biological matrix and is used in studies that rely on the quantitatively accurate and reproducible measurement of proteins across multiple samples. It requires the one-time, a priori generation of a specific measurement assay for each targeted protein. SWATH-MS is a mass spectrometric method that combines data-independent acquisition (DIA) and targeted data analysis and vastly extends the throughput of proteins that can be targeted in a sample compared to selected reaction monitoring (SRM). Here we present a compendium of highly specific assays covering more than 10,000 human proteins and enabling their targeted analysis in SWATH-MS datasets acquired from research or clinical specimens. This resource supports the confident detection and quantification of 50.9% of all human proteins annotated by UniProtKB/Swiss-Prot and is therefore expected to find wide application in basic and clinical research. Data are available via ProteomeXchange (PXD000953-954) and SWATHAtlas (SAL00016-35).

The PdNPs self-organize on the gel fibers, which supports the controlled growth as well as stabilization of PdNPs. The hybrid xerogel was used as an efficient catalyst for the Suzuki coupling reaction in water.

Published: September 2014

Molecular-level storage of environmental information in biological structures in tangible forms, and their subsequent transfer to the next generation, has been studied using the phenomenon of amyloidogenesis, which defines a biochemical condition generating highly ordered protein aggregates known as amyloid fibrils. α-Synuclein oligomers shown to experience unit assembly as the formation of amyloid fibrils were used in the present study as an environment-sensing agent. With temperature varying in 2°C intervals between 37°C and 43°C, the oligomeric unit assembly led to fibrillar polymorphism from a straight to a curly appearance, as assessed using TEM and small-angle neutron scattering; the different effects on the secondary structures were evaluated using attenuated total reflectance Fourier-transform infrared (ATR-FTIR) spectroscopy. The resulting diversified amyloid fibrils, which have distinctive molecular characteristics, were shown to be inherited by the next generation through the self-propagating property of amyloidogenesis. Storage of intangible temperature information in the diversified protein suprastructures and perpetuation of the stored information in the form of polymorphic amyloid fibrils could represent molecular inscription of environmental information into biological systems; this could further extend our understanding of any physiological/pathological significance of amyloidogenic polymorphism and be utilized in the area of nanobiotechnology to process various external signals.
Vascular calcification is coupled with phenotypic conversion of vascular smooth muscle cells through Klf5-mediated transactivation of the Runx2 promoter

Published: September 2014

Both Klf5 (Krüppel-like factor 5) and Runx2 are involved in phenotypic switching of VSMC (vascular smooth muscle cells). However, the potential link between Klf5 and Runx2 in mediating vascular calcification remains unclear. The aim of the present study was to elucidate the actual relationship between Klf5 and Runx2 in mediating VSMC calcification. We found that high Pi (phosphate) increased the expression of Klf5, which is accompanied by loss of SM α-actin and SM22α (smooth muscle 22 α), as well as gain of Runx2 expression. Overexpression of Klf5 increased, while knockdown of Klf5 decreased, Runx2 expression and calcification. Further study showed that Klf5 bound directly to the Runx2 promoter and activated its transcription. Klf5 was also induced markedly in the calcified aorta of adenine-induced uremic rats. In conclusion, we demonstrate a critical role for Klf5-mediated induction of Runx2 in high Pi -induced VSMC calcification.
The Role of Shared Decision-Making in Audiologic Rehabilitation
Authors: Pryce Helen , Hall Amanda
Published: September 2014

Shared decision-making (SDM), a component of patient-centered care, is the process in which the clinician and patient both participate in decision-making about treatment; information is shared between the parties and both agree with the decision. Shared decision-making is appropriate for health care conditions in which there is more than one evidence-based treatment or management option that have different benefits and risks. The patient's involvement ensures that the decisions regarding treatment are sensitive to the patient's values and preferences. Audiologic rehabilitation requires substantial behavior changes on the part of patients and includes benefits to their communication as well as compromises and potential risks. This article identifies the importance of shared decision-making in audiologic rehabilitation and the changes required to implement it effectively.
Design and performance projection of symmetric bipolar charge‐plasma transistor on SOI
Authors: Sahu C. , Ganguly A. , Singh J.
Published: September 2014

A novel symmetric structure of bipolar charge‐plasma transistor (BCPT) is presented. It consists of symmetrical gates with platinum on top of a thin intrinsic silicon film, which forms hole plasma in emitter and collector regions. The base contact is formed with hafnium metal to induce electron plasma; hence, a p–n–p charge‐plasma transistor is formed without any doping. The collector area that is chosen is the same as an emitter to make the device symmetrical. 2D simulation results revealed that the proposed BCPT possesses higher collector current and higher current gain than conventional p–n–p bipolar junction transistor (BJT) and almost the same characteristics such as asymmetrical p–n–p BCPT for different geometries. The major challenge of poor cut‐off frequency (fT) of BCPT is also addressed by optimising the silicon film thickness and intrinsic gaps.
Adaptive handover algorithm in heterogeneous femtocellular networks based on received signal strength and signal‐to‐interference‐plus‐noise ratio prediction
Authors: Kalbkhani Hashem , Yousefi Saleh , Shayesteh Mahrokh G.
Published: September 2014

In this study, an efficient handover algorithm based on the received signal strength (RSS) prediction is presented for two‐tier macro–femtocell networks in which, because of the fading effects of channel and short coverage range of femtocells, ping‐pong handovers may take place. In the proposed approach, first each mobile station (MS) uses the recursive least square algorithm for predicting the RSS from the candidate base stations (BSs) including both femtocell and macrocell BSs. Then, according to the predicted RSS values, several future values of signal‐to‐interference plus noise ratio (SINR) are calculated. Afterwards, the candidate list of BSs is pruned according to the estimated future SINR values and the predicted RSS of each BS. Finally, the target BS which yields the highest throughput, is opted for handover. Through extensive simulations, the effects of speed of MSs and the density of femtocell BSs on the outage probability (OP), throughput and the ping‐pong rate of MSs are studied. The results show that the proposed handover algorithm outperforms the previous ones and improves the throughput of MS while it reduces the OP and the number of ping‐pong handovers.
Unambiguous directions of arrival estimation of coherent sources using acoustic vector sensor linear arrays
Authors: Wu Yanqun , Li Guangming , Hu Zhengliang , Hu Yongming
Published: September 2014

This work investigates the problem of estimating directions of arrival (DOAs) of coherent sources without the left–right ambiguity by acoustic vector sensor linear arrays. Toeplitz matrices obtained from vector sensor cross covariance matrices are summed to obtain a new matrix with vector sensor directivities as weights. In this way, the proposed method restores the rank of the equivalent signal subspace and eliminates 2π ambiguous DOA information of sources. A robust technique is also developed to improve its performance degradation because of the velocity sensor gain uncertainty during unit conversion, such as imprecise measurements of the sensor sensitivities and the product of the water density and sound speed in the water. The methods can be implemented as a preprocessing stage before applying beamformers, such as multiple signal classification and MVDR. Theoretical analyses show that comparing with existing preprocessing techniques, the proposed methods can fully resolve the coherent sources without the left–right ambiguity while keeping the effective array aperture, and even applicable to the case of closely spaced coherent sources. Their effectiveness and performances are conducted via simulations.

Authors: Ghani Arfan , See Chan H. , Usman Ali Syed M.
Published: September 2014

This study presents energy and area‐efficient hardware architectures to map fully parallel cortical columns on reconfigurable platform – field programmable gate arrays (FPGAs). An area‐efficient architecture is proposed at the system level and benchmarked with a speech recognition application. Owing to the spatio‐temporal nature of spiking neurons it is more suitable to map such architectures on FPGAs where signals can be represented in binary form and communication can be performed through the use of spikes. The viability of implementing multiple recurrent neural reservoirs is demonstrated with a novel multiplier‐less reconfigurable architectures and a design strategy is devised for its implementation.
Compensation of thermal nonlinear effect in hybrid microsphere resonators

Published: September 2014

A hybrid structure with higher linearity to compensate the thermal refraction effect based on a ruby microsphere resonator is proposed and has been realised. The thermal refractive effect of the hybrid structure is theoretically and experimentally demonstrated, which showed that it is limited by the diameter of the resonator and the Q factor. By increasing the diameter, the transmission spectrum experiences a transition from blueshift to redshift induced by thermal absorption and when it is equal to a specific value the thermal refraction effect can be reduced or even eliminated. Experiments showed that there is no shift with varying input optical power since the thermal refraction of ruby can be completely compensated at the diameter of the microsphere d = 1.5 μm and Q = 2.3 × 106 when the KD‐310 coated thickness is 60 μm. This reported work shows that the structure could be used to improve stability and is sensitive in high‐Q resonators for applications in laser, biosensor and nonlinear optics.
Uptake of telehealth services funded by Medicare in Australia
Authors: Wade Victoria , Soar Jeffrey , Gray Len
Published: September 2014

Objective
The aim of this study is to identify the extent to which the Medicare item numbers and incentives, introduced in July 2011, have been effective in stimulating telehealth activity in Australia.

Methods
A retrospective descriptive study utilising data on the uptake of telehealth item numbers and associated in-person services, from July 2011 to April 2014, were obtained from Medicare Australia. The main outcome measures were number of telehealth services over time, plus uptake proportionate to in-person services, by jurisdiction, by speciality, and by patient gender.

Results
Specialist consultations delivered by video communication and rebated by Medicare rose to 6000 per month, which is 0.24% of the total number of specialist consultations. The highest proportional uptake was in geriatrics and psychiatry. In 52% per cent of video consultations the patient was supported by an on-site healthcare provider, most commonly a general practitioner. There were substantial jurisdictional differences. A significantly lower percentage of female patients were rebated for item 99, which is primarily used by surgeons.

Conclusions
Medicare rebates and incentives, which are generous by world standards, have resulted in specialist video consultations being provided to underserved areas, although gaps still remain that need new models of care to be developed.

What is known about the topic?
Video consultations have been rebated by Medicare since July 2011 as a means of increasing access to specialist care in rural areas, aged care facilities and Aboriginal health services.

What does this paper add?
The uptake of this telehealth initiative has grown over time, but still remains low. For half the video consultations the patient was supported by an on-site healthcare provider, most commonly a general practitioner. Geriatrics and psychiatry are the specialties with the highest proportional uptake.

What are the implications for practitioners?
New models of care with a greater focus on consultation-liaison with primary care providers need to be developed to realise the potential of this initiative and to fill continuing gaps in services.

Published: September 2014

The study investigated the effects of large or small furnished cages on laying hens. Hyline brown hens (n = 360) were placed into three treatments with six replicates: large furnished cages (LFC), small furnished cages (SFC), and conventional cages (CC). The results showed that egg production of hens in the LFC treatment was significantly lower (P < 0.05) than that in SFC and CC groups. Daily feed intake, feed : egg ratio, egg weight, and proportion of broken eggs and dirty eggs were not affected by cage types. However, Haugh unit and albumen height of the eggs from LFC and SFC hens were significantly higher (P < 0.01) than those from the CC hens. Welfare indicators (feather conditions, gait score, and fluctuating asymmetry of tibia length or wing length) in LFC and SFC hens were much better than in CC hens (P < 0.05). In conclusion, the hens in the LFC treatment had lower productivity, higher egg quality and better welfare conditions than those in the SFC and CC treatments.
Looking for Hydrogen Atoms: Neutron Crystallography Provides Novel Insights Into Protein Structure and Function
Authors: Golden Emily A. , Vrielink Alice
Published: September 2014

Neutron crystallography allows direct localization of hydrogen positions in biological macromolecules. Within enzymes, hydrogen atoms play a pivotal role in catalysis. Recent advances in instrumentation and sample preparation have helped to overcome the difficulties of performing neutron diffraction experiments on protein crystals. The application of neutron macromolecular crystallography to a growing number of proteins has yielded novel structural insights. The ability to accurately position water molecules, hydronium ions, and hydrogen atoms within protein structures has helped in the study of low-barrier hydrogen bonds and hydrogen-bonding networks. The determination of protonation states of protein side chains, substrates, and inhibitors in the context of the macromolecule has provided important insights into enzyme chemistry and ligand binding affinities, which can assist in the design of potent therapeutic agents. In this review, we give an overview of the method and highlight advances in knowledge attained through the application of neutron protein crystallography.
