Authors: Hu Meng , Wang Lili , Wang Zhigang
Published: June 2014

LetT⊂Rbe a periodic time scale in shiftsδ±with periodP∈(t0,∞)Tandt0∈Tis nonnegative and fixed. By using a multiple fixed point theorem in cones, some criteria are established for the existence and multiplicity of positive solutions in shiftsδ±for a class of higher-dimensional functional dynamic equations with impulses on time scales of the following form:xΔ(t)=A(t)x(t)+b(t)f(t,x(g(t))),  t≠tj,  t∈T,  x(tj+)=x(tj-)+Ij(x(tj)),whereA(t)=(aij(t))n×nis a nonsingular matrix with continuous real-valued functions as its elements. Finally, numerical examples are presented to illustrate the feasibility and effectiveness of the results.

Robust Switched Control Design for Nonlinear Systems Using Fuzzy Models
Authors: Souza Wallysonn Alves de , Teixeira Marcelo Carvalho Minhoto , Santim Máira Peres Alves , Cardim Rodrigo , Assunção Edvaldo
Published: June 2014

The paper proposes a new switched control design method for some classes of uncertain nonlinear plants described by Takagi‐Sugeno fuzzy models. This method uses a quadratic Lyapunov function to design the feedback controller gains based on linear matrix inequalities (LMIs). The controller gain is chosen by a switching law that returns the smallest value of the time derivative of the Lyapunov function. The proposed methodology eliminates the need to find the membership function expressions to implement the control laws. The control designs of a ball‐and‐beam system and of a magnetic levitator illustrate the procedure.

Published: June 2014

Perishable products, which include medical and pharmaceutical items as well as food products, are quite common in commerce and industries. Developing efficient network designs for storage and distribution of perishable products plays a prominent role in the cost and quality of these products. This paper aims to investigate and analyze the impact of applying an integrated approach for network design of perishable products. For this purpose, the problem has been formulated as a mixed integer nonlinear mathematical model that integrates inventory control and facility location decisions. To solve the integrated model, a memetic algorithm (MA) is developed in this study. For verification of the proposed algorithm, its results are compared with the results of an adapted Lagrangian relaxation heuristic algorithm from the literature. Moreover, sensitivity analysis of the main parameters of the model is conducted to compare the results of the integrated approach with a decoupled method. The results show that as the products become more perishable, application of an integrated method becomes more reasonable in comparison with the decoupled one.
Modified Decomposition Method with New Inverse Differential Operators for Solving Singular Nonlinear IVPs in First- and Second-Order PDEs Arising in Fluid Mechanics
Authors: Dalir Nemat
Published: June 2014

Singular nonlinear initial-value problems (IVPs) in first-order and second-order partial differential equations (PDEs) arising in fluid mechanics are semianalytically solved. To achieve this, the modified decomposition method (MDM) is used in conjunction with some new inverse differential operators. In other words, new inverse differential operators are developed for the MDM and used with the MDM to solve first- and second-order singular nonlinear PDEs. The results of the solutions by the MDM together with new inverse operators are compared with the existing exact analytical solutions. The comparisons show excellent agreement.
Towards Self-Awareness Privacy Protection for Internet of Things Data Collection
Authors: Wong Kok-Seng , Kim Myung Ho
Published: June 2014

The Internet of Things (IoT) is now an emerging global Internet-based information architecture used to facilitate the exchange of goods and services. IoT-related applications are aiming to bring technology to people anytime and anywhere, with any device. However, the use of IoT raises a privacy concern because data will be collected automatically from the network devices and objects which are embedded with IoT technologies. In the current applications, data collector is a dominant player who enforces the secure protocol that cannot be verified by the data owners. In view of this, some of the respondents might refuse to contribute their personal data or submit inaccurate data. In this paper, we study a self-awareness data collection protocol to raise the confidence of the respondents when submitting their personal data to the data collector. Our self-awareness protocol requires each respondent to help others in preserving his privacy. The communication (respondents and data collector) and collaboration (among respondents) in our solution will be performed automatically.

Authors: Tsai Pai-Yang , Huang Hou-Kuei , Sung Chien-Min , Kan Ming-Chi , Wang Yeong-Her
Published: June 2014

The temperature-dependent optical, electrical, and thermal properties of flip-chip light emitting diodes (FCLEDs) with diamond-like carbon (DLC) heat-spreading layers were investigated. On the basis of the measured results in the 20°C to 100°C temperature range, a significant performance improvement can be achieved for FCLEDs with DLC heat-spreading layers (DLC-FCLED) compared with FCLEDs without DLC heat-spreading layers (non-DLC-FCLED). The external quantum efficiency (EQE) of the DLC-FCLED improves by 9% at an injection current of 1000 mA and a temperature of 100°C. The forward voltage and spectra variations are smaller than those of non-DLC-FCLEDs. The DLC-FCLED provides high efficiency and high stability performance for high-power and high-temperature applications.
Least Squares Based Iterative Algorithm for the Coupled Sylvester Matrix Equations
Authors: Yin Hongcai , Zhang Huamin
Published: June 2014

By analyzing the eigenvalues of the related matrices, the convergence analysis of the least squares based iteration is given for solving the coupled Sylvester equations AX + YB = C and DX + YE = F in this paper. The analysis shows that the optimal convergence factor of this iterative algorithm is 1. In addition, the proposed iterative algorithm can solve the generalized Sylvester equation AXB + CXD = F. The analysis demonstrates that if the matrix equation has a unique solution then the least squares based iterative solution converges to the exact solution for any initial values. A numerical example illustrates the effectiveness of the proposed algorithm.

Authors: Yu Kaijiang , Yang Junqi
Published: June 2014

This paper presents a real-time optimal control approach for the energy management problem of hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) with slope information during car following. The new features of this study are as follows. First, the proposed method can optimize the engine operating points and the driving profile simultaneously. Second, the proposed method gives the freedom of vehicle spacing between the preceding vehicle and the host vehicle. Third, using the HEV/PHEV property, the desired battery state of charge is designed according to the road slopes for better recuperation of free braking energy. Fourth, all of the vehicle operating modes engine charge, electric vehicle, motor assist and electric continuously variable transmission, and regenerative braking, can be realized using the proposed real-time optimal control approach. Computer simulation results are shown among the nonlinear real-time optimal control approach and the ADVISOR rule-based approach. The conclusion is that the nonlinear real-time optimal control approach is effective for the energy management problem of the HEV/PHEV system during car following.
Magnetic Study of the Heated and Unheated Sedimentary Fillings of Sebkha Mhabeul, Southeast Tunisia: A Geophysical Method for Paleoclimatic Investigation and Tephrochronological Dating
Authors: Essefi Elhoucine , Mefteh Samir , Medhioub Mounir , Yaich Chokri
Published: June 2014

This paper is meant to investigate the climatic and volcanic signals within the sedimentary filling of sebkha Mhabeul through a thermomagnetic study of a 37 cm length core. Values of the magnetic susceptibility at ambient temperature show that the core encompasses four climatic stages: the Warming Present (WP), the Little Ice Age (Late LIA), Early Little Ice Age (ELIA), and the Medieval Climate Anomalies (MCA). Added to the subcycles, the spectral analysis shows the individualization of an 888 yr cycle probably related to solar activity. The heating at 250°C is good-for-nothing since it was useful neither for climatic investigation nor for tephras layers detection. Heating at 700°C generated the complete loss of the climatic signal. On the other hand, it allowed the detection of the previously identified tephras layers. Further, it highlighted the presence of other tephras layers. The extraction by the bromoform confirms the presence of these tephras. The use of the same methodology may allow the detection of tephras layers within other sebkhas.
Traveling Wave Solutions of the Kadomtsev-Petviashvili-Benjamin-Bona-Mahony Equation
Authors: Ouyang Zhengyong
Published: June 2014

We use bifurcation method of dynamical systems to study exact traveling wave solutions of a nonlinear evolution equation. We obtain exact explicit expressions of bell-shaped solitary wave solutions involving more free parameters, and some existing results are corrected and improved. Also, we get some new exact periodic wave solutions in parameter forms of the Jacobian elliptic function. Further, we find that the bell-shaped waves are limits of the periodic waves in some sense. The results imply that we can deduce bell-shaped waves from periodic waves for some nonlinear evolution equations.

Authors: Custódio Lima Juliana , Nagasako Cristiane Kibune , Montes Ciro Garcia , Barcelos Irene Harumi Kamata , de Carvalho Rita Barbosa , Mesquita Maria Aparecida
Published: June 2014

Lipoid proteinosis is a rare autosomal recessive disease characterized by the deposition of hyaline material in the skin and internal organs. The main clinical features are hoarseness and typical skin lesions. In this report we describe the endoscopic and radiologic findings in a Brazilian female patient presenting extensive gastrointestinal involvement and the evolution of the detected lesions in ten years of follow-up. Initial upper endoscopy and colonoscopy showed a similar pattern of multiple yellowish nodules throughout the esophagus, stomach, duodenum, and colons. Histological analysis confirmed the diagnosis of lipoid proteinosis. In addition, small bowel follow through demonstrated numerous well defined, round, small filling defects throughout the jejunum. Ten years later, the esophageal lesions remained the same, but none of the previous alterations were detected in the stomach, duodenum, and colons. In conclusion, lipoid proteinosis may affect all gastrointestinal organs with the same pattern of macroscopic and microscopic lesions. Some lesions may regress with increasing age.
A Scheduling Problem in the Baking Industry
Authors: da Silva Felipe Augusto Moreira , Moretti Antonio Carlos , de Azevedo Anibal Tavares
Published: June 2014

This paper addresses a scheduling problem in an actual industrial environment of a baking industry where production rates have been growing every year and the need for optimized planning becomes increasingly important in order to address all the features presented by the problem. This problem contains relevant aspects of production, such as parallel production, setup time, batch production, and delivery date. We will also consider several aspects pertaining to transportation, such as the transportation capacity with different vehicles and sales production with several customers. This approach studies an atypical problem compared to those that have already been studied in literature. In order to solve the problem, we suggest two approaches: using the greedy heuristic and the genetic algorithm, which will be compared to small problems with the optimal solution solved as an integer linear programming problem, and we will present results for a real example compared with its upper bounds. The work provides us with a new mathematical formulation of scheduling problem that is not based on traveling salesman problem. It considers delivery date and the profit maximization and not the makespan minimization. And it also provides an analysis of the algorithms runtime.
3D Alternating Direction TV-Based Cone-Beam CT Reconstruction with Efficient GPU Implementation
Authors: Cai Ailong , Wang Linyuan , Zhang Hanming , Yan Bin , Li Lei , Xi Xiaoqi , Guan Min , Li Jianxin
Published: June 2014

Iterative image reconstruction (IIR) with sparsity-exploiting methods, such as total variation (TV) minimization, claims potentially large reductions in sampling requirements. However, the computation complexity becomes a heavy burden, especially in 3D reconstruction situations. In order to improve the performance for iterative reconstruction, an efficient IIR algorithm for cone-beam computed tomography (CBCT) with GPU implementation has been proposed in this paper. In the first place, an algorithm based on alternating direction total variation using local linearization and proximity technique is proposed for CBCT reconstruction. The applied proximal technique avoids the horrible pseudoinverse computation of big matrix which makes the proposed algorithm applicable and efficient for CBCT imaging. The iteration for this algorithm is simple but convergent. The simulation and real CT data reconstruction results indicate that the proposed algorithm is both fast and accurate. The GPU implementation shows an excellent acceleration ratio of more than 100 compared with CPU computation without losing numerical accuracy. The runtime for the new 3D algorithm is about 6.8 seconds per loop with the image size of256×256×256and 36 projections of the size of512×512.

Published: June 2014

Purpose: Biomarkers for the early detection of pancreatic cancer are urgently needed. The primary objective of this study was to evaluate whether increased levels of serum CA19-9, CA125, CEACAM1, and REG3A are present before clinical presentation of pancreatic cancer and to assess the performance of combined markers for early detection and prognosis.

Experimental Design: This nested case–control study within the UKCTOCS included 118 single and 143 serial serum samples from 154 postmenopausal women who were subsequently diagnosed with pancreatic cancer and 304 matched noncancer controls. Samples were split randomly into independent training and test sets. CA19-9, CA125, CEACAM1, and REG3A were measured using ELISA and/or CLIA. Performance of markers to detect cancers at different times before diagnosis and for prognosis was evaluated.

Results: At 95% specificity, CA19-9 (>37 U/mL) had a sensitivity of 68% up to 1 year, and 53% up to 2 years before diagnosis. Combining CA19-9 and CA125 improved sensitivity as CA125 was elevated (>30 U/mL) in approximately 20% of CA19-9–negative cases. CEACAM1 and REG3A were late markers adding little in combined models. Average lead times of 20 to 23 months were estimated for test-positive cases. Prediagnostic levels of CA19-9 and CA125 were associated with poor overall survival (HR, 2.69 and 3.15, respectively).

Conclusions: CA19-9 and CA125 have encouraging sensitivity for detecting preclinical pancreatic cancer, and both markers can be used as prognostic tools. This work challenges the prevailing view that CA19-9 is upregulated late in the course of pancreatic cancer development. Clin Cancer Res; 21(3); 622–31. ©2014 AACR.

Authors: Moon Jeonggeun , Yoon Ji Hyun , Choi Eui-Young , Chung Wook-Jin , Kang Woong Chol , Rim Se-Joong
Published: June 2014

Objectives: To identify differences in cardiac hemodynamic changes between the Valsalva maneuver and nitroglycerin (NTG) administration. Methods: Fifty-three subjects (37 men, 43 ± 12 years) with normal cardiac function [left ventricular ejection fraction ≥55%, early to late mitral inflow velocity ratio (E/A) ≥1, left atrial volume index ≤34 ml/m2 and early diastolic mitral annulus velocity (E') ≥8 cm/s] were enrolled. Doppler parameters were determined at rest, during the Valsalva maneuver and after NTG administration. Results: Decreased E, A and E/A were observed both during the Valsalva maneuver and after NTG administration (p < 0.0001 for all). However, the reduction in E (ΔEValsalva: -30 ± 16 cm/s vs. ΔENTG: -17 ± 17 cm/s) and E/A (ΔE/AValsalva: -0.37 ± 0.28 vs. ΔE/ANTG: -0.19 ± 0.25) and the prolongation of the deceleration time (DT) of E (ΔDTValsalva: 105 ± 74 ms vs. ΔDTNTG: 83 ± 63 ms) were more prominent during the Valsalva maneuver than with NTG administration (p < 0.0001 for all). Particularly, a greater decrease in E' was observed during the Valsalva maneuver (ΔE'Valsalva: -3 ± 2 cm/s vs. ΔE'NTG: -2 ± 2 cm/s, p < 0.0001). Eighteen subjects (34%) showed ΔE/A ≥0.5 during the Valsalva maneuver; thus, they were mislabeled as ‘pseudonormal', while only 3 subjects (6%) showed ΔE/A ≥0.5 after NTG administration. Conclusions: The Valsalva maneuver not only decreases preload but also affects myocardial performance, thus, its use can result in the mislabeling of normal subjects as pseudonormal.

Published: June 2014

Background: The identification of patients at high risk for adverse outcomes [death, unplanned readmission to emergency department (ED)/hospital, functional decline] plays an important role in emergency medicine. The Identification of Seniors at Risk (ISAR) instrument is one of the most commonly used and best-validated screening tools. As to the authors' knowledge so far there are no data on any screening tool for the identification of older patients at risk for a negative outcome in Germany. Objectives: To evaluate the validity of the ISAR screening tool in a German ED. Design: This was a prospective single-center observational cohort study in an ED of an urban university-affiliated hospital. Participants were 520 patients aged ≥75 years consecutively admitted to the ED. Measurements: The German version of the ISAR screening tool was administered directly after triage of the patients. Follow-up telephone interviews to assess outcome variables were conducted 28 and 180 days after the index visit in the ED. The primary end point was death from any cause or hospitalization or recurrent ED visit or change of residency into a long-term care facility on day 28 after the index ED visit. Results: The mean age ± SD was 82.8 ± 5.0 years. According to ISAR, 425 patients (81.7%) scored ≥2 points, and 315 patients (60.5%) scored ≥3 points. The combined primary end point was observed in 250 of 520 patients (48.1%) on day 28 and in 260 patients (50.0%) on day 180. Using a continuous ISAR score the area under the curve on day 28 was 0.621 (95% confidence interval, CI 0.573-0.669) and 0.661 (95% CI 0.615-0.708) on day 180, respectively. Conclusion: The German version of the ISAR screening tool acceptably identified elderly patients in the ED with an increased risk of a negative outcome. Using the cutoff ≥3 points instead of ≥2 points yielded better overall results.
An Analysis of the Impact of Cell Phone Use on Depressive Symptoms among Japanese Elders
Authors: Minagawa Yuka , Saito Yasuhiko
Published: June 2014

Background: There has been increasing interest in the impact of information and communication technologies, such as the computer and Internet, on physical and mental health status, but relatively little is known about the health effects of using cell phones. Objective: This study investigates how cell phone usage is associated with levels of depressive symptoms among Japanese men and women aged 65 years and older. We focus on social relationships, particularly intergenerational relationships between older parents and adult children, as a possible mediator in the association of cell phone use with late-life depressive symptoms. We therefore hypothesize that using cell phones contributes to the psychological well-being of older adults primarily through encouraging social relationships. Methods: We used 4 waves of data from the Nihon University Japanese Longitudinal Study of Aging (2001-2009) to analyze the impact of cell phone use on depressive symptoms. Results are based on ordinary least squares regression analyses. Results: Although the use of cell phones was related to lower levels of depressive symptoms among elderly Japanese people, controlling for sociodemographic characteristics and physical health conditions wiped out the effects for men. In contrast, the protective effects of using cell phones persisted among women, even net of all controls. Moreover, the impact of using cell phones was not explained by filial relationship measures, suggesting that cell phone use influences the mental health of older women independently of social engagement. Conclusions: Among the many advantages brought about by recent technological developments, cell phones appear to be an important contributor to the psychological well-being of Japanese elders. Researchers and policy makers should prioritize access to new technologies for older adults.
Epidermal Growth Factor Mutation as a Diagnostic and Therapeutic Target in Metastatic Poorly Differentiated Thyroid Carcinoma: A Case Report and Review of the Literature
Authors: Lote Hazel , Bhosle Jaishree , Thway Khin , Newbold Kate , O'Brien Mary
Published: June 2014

Poorly differentiated cancers are a diagnostic and therapeutic challenge in oncology. New therapies are needed for patients with poorly differentiated thyroid carcinoma (PDTC) or anaplastic thyroid cancer, as these patients often present with advanced disease and effective systemic treatment options are currently limited. Epidermal growth factor (EGFR) mutations may occur in PDTC more often than previously thought. However, there are fewer than 6 cases reported in the literature where EGFR tyrosine kinase inhibitors (TKIs) (such as erlotinib or gefitinib) were used to target EGFR mutations in PDTC. Here, we present the case of a 79-year-old male with metastatic PDTC with an EGFR mutation who responded to treatment with the selective EGFR TKI erlotinib, with a progression-free survival of more than 11 months. A lung primary rather than a thyroid primary was initially detected. We suggest that the EGFR status should be analysed at diagnosis in any patient with a poorly differentiated tumour. The presence of an EGFR mutation may provide an effective therapeutic pathway for these patients. This pathway requires further investigation and consideration in the future.

A Etnopoesia de Hubert Fichte
Authors: Alcântara Plácido
Published: June 2014

O artigo trata das relações entre Antropologia e LIteratura, mais precisamente de como elas são problematizadas pelo escritor alemão Hubert Fichte, cujos textos, de ficção, são resultado do estudo da teoria e da aplicação de métodos da Antropologia. Versando sobre o sincretismo das religiões afro-americanas, a obra de Fichte, a partir dos anos setenta, é denominada, pelo próprio autor, de etnopoesia, isto é, a espressão literária do saber antropológico. Ao refjeitar a prosa científica, o "etnopoeta" pretende questionar a pretensa objetividade e a utópica onipotência de pesquisadores de certas correntes da Antropologia. Faz-se por fim, um paralelo entre crítica fichteana e a dos antropológos ditos pós-modernos, ressaltando-se que as afinidades aparentes entre eles e a Etnopoesia escondem divergências fundamentais.

Memantine Enhances Recovery From Stroke
Authors: López-Valdés Héctor E. , Clarkson Andrew N. , Ao Yan , Charles Andrew C. , Carmichael Stanley Thomas , Sofroniew Michael V. , Brennan Kevin C.
Published: June 2014

Background and Purpose—

Stroke treatment is constrained by limited treatment windows and the clinical inefficacy of agents that showed preclinical promise. Yet animal and clinical data suggest considerable poststroke plasticity, which could allow treatment with recovery-modulating agents. Memantine is a well-tolerated N-methyl-
D
-aspartate glutamate receptor antagonist in common use for Alzheimer disease.

Methods—

Memantine, 30 mg/kg per day, or vehicle, was delivered chronically in drinking water beginning >2 hours after photothrombotic stroke.

Results—

Although there was no difference in infarct size, behavior, or optical intrinsic signal maps in the first 7 days after stroke, mice treated chronically with memantine showed significant improvements in motor control, measured by cylinder test and grid-walking performance, compared with vehicle-treated animals. Optical intrinsic signal revealed an increased area of forepaw sensory maps at 28 days after stroke. There was decreased reactive astrogliosis and increased vascular density around the infarcted cortex. Peri-infarct Western blots revealed increased brain-derived neurotrophic factor and phosphorylated-tropomyosin–related kinase-B receptor expression.

Conclusions—

Our results suggest that memantine improves stroke outcomes in an apparently non-neuroprotective manner involving increased brain-derived neurotrophic factor signaling, reduced reactive astrogliosis, and improved vascularization, associated with improved recovery of sensory and motor cortical function. The clinical availability and tolerability of memantine make it an attractive candidate for clinical translation.

Published: June 2014

Background and Purpose—

A promising method for identifying hemodynamic impairment that may serve as a biomarker for stroke risk in patients with intracranial stenosis is cerebrovascular reactivity (CVR) mapping using noninvasive MRI. Here, abilities to measure CVR safely in the clinic using hypercarbic hyperoxic (carbogen) gas challenges, which increase oxygen delivery to tissue, are investigated.

Methods—

In sequence with structural and angiographic imaging, blood oxygenation level–dependent carbogen-induced CVR scans were performed in patients with symptomatic intracranial stenosis (n=92) and control (n=10) volunteers, with a subgroup of patients (n=57) undergoing cerebral blood flow–weighted pseudocontinuous arterial spin labeling CVR. Subjects were stratified for 4 substudies to evaluate relationships between (1) carbogen and hypercarbic normoxic CVR in healthy tissue (n=10), (2) carbogen cerebral blood flow CVR and blood oxygenation level–dependent CVR in intracranial stenosis patients (n=57), (3) carbogen CVR and clinical measures of disease in patients with asymmetrical intracranial atherosclerotic (n=31) and moyamoya (n=29) disease, and (4) the CVR scan and immediate and longer-term complications (n=92).

Results—

Noninvasive blood oxygenation level–dependent carbogen-induced CVR values correlate with (1) lobar hypercarbic normoxic gas stimuli in healthy tissue (
R
=0.92;
P
<0.001), (2) carbogen-induced cerebral blood flow CVR in patients with intracranial stenosis (
R
=0.30–0.33;
P
<0.012), and (3) angiographic measures of disease severity both in atherosclerotic and moyamoya patients after appropriate processing. No immediate stroke-related complications were reported in response to carbogen administration; longer-term neurological events fell within the range for expected events in this patient population.

Conclusions—

Carbogen-induced CVR elicited no added adverse events and provided a surrogate marker of cerebrovascular reserve consistent with intracranial vasculopathy.
Revision of the genus Pelecinobaccha Shannon, description of Relictanum gen. nov., and redescription of Atylobaccha flukiella (Curran, 1941) (Diptera: Syrphidae)

Published: June 2014

Recent phylogenetic analyses of Ocyptamus Macquart, 1834 (Diptera, Syrphidae) confirmed the paraphyly of this genus and provided evidence to divide it into several monophyletic subgroups, of which the largest is the clade traditionally treated as the Ocyptamus tristis species group. This group is here redefined, divided into the genera Pelecinobaccha Shannon, 1927 and Relictanum gen. nov., and revised along with the closely related and newly resurrected genus Atylobaccha Hull, 1949. Twenty-four new species (22 in Pelecinobaccha and two in Relictanum) are described and 35 species (27 in Pelecinobaccha, seven in Relictanum and Atylobaccha flukiella Curran, 1941) are redescribed. Pelecinobaccha is divided into four species groups (P. adspersa species group, P. brevipennis species group, P. peruviana species group and P. susio species group). An identification key, illustrations and distribution maps for all species from this study are also presented.

Ghost shrimp Calliax de Saint Laurent, 1973 (Decapoda: Axiidea: Callianassidae) in the fossil record: systematics, palaeoecology and palaeobiogeography
Authors: HYŽNÝ MATÚŠ , GAŠPARIČ ROK
Published: June 2014

Ghost shrimps of the family Callianassidae are very common in the fossil record, but mostly as isolated cheliped elements only. The assignment to biologically defined genera, diagnosed on the basis of soft part morphology, is thus rather difficult. In this respect, proxy characters present on chelipeds that are the most durable ghost shrimp remains are needed to ascribe fossil material to extant genera. The genus Calliax de Saint Laurent, 1973 has been particularly obscure in this respect. Thorough comparison of extant members of the genus resulted in evaluation of characters present on chelipeds being taxonomically important on the genus level, specifically: 1) rectangular major P1 propodus with two ridges on the base of the fixed finger extending onto manus; 2) major P1 fingers relatively short; and 3) minor P1 chela with dactylus longer than fixed finger and possessing a wide gap between fingers. On this basis, Callianassa michelottii A. Milne Edwards, 1860, from the Oligocene and Miocene of Europe is herein reassigned to Calliax. Further re-examination of the ghost shrimp fossil record revealed that C. szobensis Müller, 1984, from the Middle Miocene of Hungary represents the same animal as C. michelottii and they are synomymised herein. The known geographic distribution of C. michelottii is expanded by the first confirmed occurrence of the species in Slovakia. All occurrences of C. michelottii known to date are reviewed and documented. The presence of Calliax michelottii comb. nov. may be considered an indicator of deeper marine settings. Based on the scarce fossil record known to date, Calliax has a Tethyan origin; it supposedly migrated westward to establish present day communities in the Caribbean sometime before the Middle Miocene.

Time, Probe Type, and Temperature Variable Bias Corrections to Historical Expendable Bathythermograph Observations
Authors: Cheng Lijing , Zhu Jiang , Cowley Rebecca , Boyer Tim , Wijffels Susan
Published: June 2014

Systematic biases in historical expendable bathythermograph (XBT) data are examined using two datasets: 4151 XBT–CTD side-by-side pairs from 1967 to 2011 and 218 653 global-scale XBT–CTD pairs (within one month and 1°) extracted from the World Ocean Database 2009 (WOD09) from 1966 to 2010. Using the side-by-side dataset, it was found that both the pure thermal bias and the XBT fall rate (from which the depth of observation is calculated) increase with water temperature. Correlations between the terminal velocity A and deceleration B terms of the fall-rate equation (FRE) and between A and the offset from the surface terms are obtained, with A as the dominant term in XBT fall-rate behavior. To quantify the time variation of the XBT fall-rate and pure temperature biases, global-scale XBT–CTD pairs are used. Based on the results from the two datasets, a new correction scheme for historical XBT data is proposed for nine independent probe-type groups. The scheme includes corrections for both temperature and depth records, which are all variable with calendar year, water temperature, and probe type. The results confirm those found in previous studies: a slowing in fall rate during the 1970s and 2000s and the large pure thermal biases during 1970–85. The performance of nine different correction schemes is compared. After the proposed corrections are applied to the XBT data in the WOD09 dataset, global ocean heat content from 1967 to 2010 is reestimated.
LES of a Spatially Developing Atmospheric Boundary Layer: Application of a Fringe Method for the Stratocumulus to Shallow Cumulus Cloud Transition
Authors: Inoue M. , Matheou G. , Teixeira J.
Published: June 2014

An arrangement of a large-eddy simulation (LES) is described that facilitates a spatially developing thermally stratified atmospheric boundary layer (ABL). When the inflow and outflow boundary conditions are specified, the LES of stably stratified ABL turns out to be challenging because spurious reflections of waves at the boundary accumulate inside the domain. To tackle this problem, a fringe method with an auxiliary LES running concurrently is applied to enforce upstream/downstream boundary conditions. An artificial forcing term is applied within a fringe region located at the beginning of the main LES domain in order to ensure statistically stationary inflow boundary conditions. The auxiliary LES, which is horizontally homogeneous in a doubly periodic domain, is used to determine the inflow condition of the main LES domain. The present scheme is used to provide an Eulerian perspective of the stratocumulus to shallow cumulus cloud (Sc–Cu) transition, one of the key cloud regimes over the subtropical ocean. In this study, the transition is triggered by increasing the sea surface temperature (SST) and the LES runs until a statistically steady evolution of the Sc–Cu transition is achieved. The flow statistics are compared with those from a recycling-type method and it is found that the fringe method is more suitable for the current applications.
Formulation and Characterization of a Porous, Elastomeric Biomaterial for Vocal Fold Tissue Engineering Research
Authors: Gaston Joel , Bartlett Rebecca S. , Klemuk Sarah A. , Thibeault Susan L.
Published: June 2014

Objective:

Biomaterials able to mimic the mechanical properties of vocal fold tissue may be particularly useful for furnishing a 3-dimensional microenvironment allowing for in vitro investigation of cell and molecular responses to vibration. Motivated by the dearth of biomaterials available for use in an in vitro model for vocal fold tissue, we investigated polyether polyurethane (PEU) matrices, which are porous, mechanically tunable biomaterials that are inexpensive and require only standard laboratory equipment for fabrication.

Methods:

Rheology, dynamic mechanical analysis, and scanning electron microscopy were performed on PEU matrices at 5%, 10%, and 20% w/v mass concentrations.

Results:

For 5%, 10%, and 20% w/v concentrations, shear storage moduli were 2 kPa, 3.4 kPa, and 6 kPa, respectively, with shear loss moduli being 0.2 kPa, 0.38 kPa, and 0.62 kPa, respectively. Storage moduli responded to applied frequency as a linear function. Mercury intrusion porosimetry revealed that all 3 mass concentrations of PEU have a similar overall percentage porosity but differ in pore architecture.

Conclusion:

Twenty-µm diameter pores are ideal for cell seeding, and a range of mechanical properties indicates that the higher mass concentration PEU formulations are best suited for mimicking the viscoelastic properties of vocal fold tissue for in vitro research.
African Versus Caucasian Faces in a Visual Expectation Paradigm

Published: June 2014

This article focuses on sequence learning on the Visual Expectation Paradigm (VExP) using human faces as stimulus material. For a sample of 133 Caucasian German infants assessed longitudinally at 3 and 6 months of age, a previous study has shown that the response latency of 6-month-old infants was shorter when the infants solved the task with Caucasian own-race faces in contrast to African other-race faces. The advantage for own-race faces occurs at the same age the Other-Race-Effect (ORE) has been reported to emerge. As studies on ORE development have shown the phenomenon in infants from various cultural backgrounds, the follow-up question to be answered here is whether the performance differences on the VExP can also be found in other than Caucasian infants. As a complement to the German sample, 30 African infants from Cameroon were assessed longitudinally with the same VExP task at ages 3 and 6 months. Our results indicate that perception differences between own-race and other-race faces influence performance on the VExP in both samples. As expected, the Cameroonian infants improved performance on the VExP from 3 to 6 months only in their own-race African faces condition.

Published: June 2014

Introduction: Critically ill patients placed on enteral nutrition (EN) are usually underfed. A volume‐based feeding (VBF) protocol designed to adjust the infusion rate to make up for interruptions in delivery should provide a greater volume of EN than the more common fixed hourly rate‐based feeding (RBF) method. Methods: This single‐center, randomized (3:1; VBF/RBF) prospective study evaluated critically ill patients on mechanical ventilation expected to receive EN for ≥3 days. Once goal rate was achieved, the randomized feeding strategy was implemented. In the VBF group, physicians used a total goal volume of feeds to determine an hourly rate. For the RBF group, physicians determined a constant hourly rate of infusion to meet goal feeds. Results: Sixty‐three patients were enrolled in the study with a mean age of 52.6 years (60% male). Six patients were excluded after randomization because of early extubation. The VBF group (n = 37) received 92.9% of goal caloric requirements with a mean caloric deficit of −776.0 kcal compared with the RBF group (n = 20), which received 80.9% of goal calories (P = .01) and a caloric deficit of −1933.8 kcal (P = .01). Uninterrupted EN was delivered for 51.7% of all EN days in VFB patients compared with 54.5% in RBF patients. On days when feeding was interrupted, VFB patients overall received a mean 77.6% of goal calories (while RBF patients received 61.5% of goal calories, P = .001). No vomiting, regurgitation, or feeding intolerance occurred due to VBF. Conclusions: A VBF strategy is safe and improves delivery to better meet caloric requirements than the standard more commonly used rate‐based strategy.
