Repeatability of Hypoxia Tolerance of Individual Juvenile Striped Bass Morone saxatilis and Effects of Social Status

Chesapeake Bay is the primary nursery for striped bass (Morone saxatilis), which are increasingly being exposed to hypoxic waters. Tolerance to hypoxia in fish is generally determined by a single exposure of an isolated individual or by exposing large groups of conspecifics to hypoxia without regard to social status. The importance of social context in determining physiological responses to stressors is being increasingly recognized. To determine whether social interactions influence hypoxia tolerance (HT) in striped bass, loss of equilibrium HT was assessed in the same fish while manipulating the social environment around it. Small group settings were used to be more representative of the normal sociality experienced by this species than the paired encounters typically used. After establishing the dominance hierarchy within a group of fish, HT was determined collectively for the individuals in that group, and then new groups were constructed from the same pool of fish. Individuals could then be followed across multiple settings for both repeatability of HT and hierarchy position ( X ¯ = 4.2 ± 0.91 SD groups per individual). HT increased with repeated exposures to hypoxia ( P < 0.001 ), with a significant increase by a third exposure ( P = 0.004 ). Despite this changing HT, rank order of HT was significantly repeatable across trials for 6 mo ( P = 0.012 ). Social status was significantly repeatable across trials of different group composition ( P = 0.02 ) and unrelated to growth rate but affected HT weakly in a complex interaction with size. Final HT was significantly correlated with blood [hemoglobin] and hematocrit. The repeatability and large intraspecific variance of HT in juvenile striped bass suggest that HT is potentially an important determinant of Darwinian fitness in an increasingly hypoxic Chesapeake Bay.
Dicationic Alkylammonium Bromide Gemini Surfactants. Membrane Perturbation and Skin Irritation

Dicationic alkylammonium bromide gemini surfactants represent a class of amphiphiles potentially effective as skin permeation enhancers. However, only a limited number of studies has been dedicated to the evaluation of the respective cytotoxicity, and none directed to skin irritation endpoints. Supported on a cell viability study, the cytotoxicity of gemini surfactants of variable tail and spacer length was assessed. For this purpose, keratinocyte cells from human skin (NCTC 2544 cell line), frequently used as a model for skin irritation, were employed. The impact of the different gemini surfactants on the permeability and morphology of model vesicles was additionally investigated by measuring the leakage of calcein fluorescent dye and analyzing the NMR spectra of 31P, respectively. Detail on the interaction of gemini molecules with model membranes was also provided by a systematic differential scanning calorimetry (DSC) and molecular dynamics (MD) simulation. An irreversible impact on the viability of the NCTC 2544 cell line was observed for gemini concentrations higher than 25 mM, while no cytotoxicity was found for any of the surfactants in a concentration range up to 10 mM. A higher cytotoxicity was also found for gemini surfactants presenting longer spacer and shorter tails. The same trend was obtained in the calorimetric and permeability studies, with the gemini of longest spacer promoting the highest degree of membrane destabilization. Additional structural and dynamical characterization of the various systems, obtained by 31P NMR and MD, provide some insight on the relationship between the architecture of gemini surfactants and the respective perturbation mechanism.
Reliability of Goniometric Measurements of Hip Motion in Spastic Cerebral Palsy

Reliability of goniometric measurements of ranges of motion in the right hip of four children with mild or moderate spastic diplegia was studied by comparing results when physical therapists used specific and non‐specific measurement instructions. Measurements of hip extension, abduction and external rotation were made. The use of specific measurement instructions improved inter‐rater reliability only in the case of external rotation. Inter‐session reliability was not improved by the use of specific measurement instructions. It is concluded that goniometric measurements have such a low level of reliability that they can only be used to assist clinical judgment, and that they are not sufficiently reliable to be used in studies of cerebral palsy.
External and Intrinsic Plagiarism Detection Using a Cross-Lingual Retrieval and Segmentation System - Lab Report for PAN at CLEF 2010

We present our hybrid system for the PAN challenge at CLEF 2010. Our system performs plagiarism detection for translated and non-translated exter- nally as well as intrinsically plagiarized document passages. Our external plagia- rism detection approach is formulated as an information retrieval problem, using heuristic post processing to arrive at the final detection results. For the retrieval step, source documents are split into overlapping blocks which are indexed via a Lucene instance. Suspicious documents are similarly split into consecutive over- lapping boolean queries which are performed on the Lucene index to retrieve an initial set of potentially plagiarized passages. For performance reasons queries might get rejected via a heuristic before actually being executed. Candidate hits gathered via the retrieval step are further post-processed by performing sequence analysis on the passages retrieved from the index with respect to the passages used for querying the index. By applying several merge heuristics bigger blocks are formed from matching sequences. German and Spanish source documents are first translated using word alignment on the Europarl corpus before enter- ing the above detection process. For each word in a translated document several translations are produced. Intrinsic plagiarism detection is done by finding major changes in style measured via word suffixes after the documents have been parti- tioned by an linear text segmentation algorithm. Our approach lead us to the third overall rank with an overall score of 0.6948.
UCAN: Unified Cellular and Ad-Hoc Network

In third-generation (3G) wireless data networks, providing service to low data-rate users is required for maintaining fairness, but at the cost of reducing the cell’s aggregate throughput. In this paper, we propose the Unified Cellular and Ad-Hoc Network (UCAN) architecture for enhancing cell throughput, while maintaining fairness. In UCAN, a mobile client has both 3G cellular link and IEEE 802.11-based peerto-peer links. The 3G base station forwards packets for destination clients with poor channel quality to proxy clients with better channel quality. The proxy clients then use an ad-hoc network composed of other mobile clients and IEEE 802.11 wireless links to forward the packets to the appropriate destinations, thereby improving cell throughput. We refine the 3G base station scheduling algorithm so that the throughput gains are distributed proportional to users’ average channel rates, thereby maintaining fairness. With the UCAN architecture in place, we propose novel greedy and on-demand protocols for proxy discovery and ad-hoc routing that explicitly leverage the existence of the 3G infrastructure to reduce complexity and improve reliability. We further propose secure crediting mechanisms to motivate users that are not actively receiving to participate in relaying packets for others. Through extensive simulations with HDR and IEEE 802.11b, we show that the UCAN architecture can increase individual user’s throughput by up to 225% and the aggregate throughput of the HDR downlink by up to 65%.
Inhibition of autophagy potentiates the proliferation inhibition activity of microRNA-7 in human hepatocellular carcinoma cells

MicroRNAs (miRNAs/miRs) are important molecules that are able to regulate multiple cellular processes in cancer cells. miR-7 has been previously identified as a tumor suppressive miRNA in several types of cancer. The aim of the present study was to investigate whether miR-7 is able to regulate autophagy in hepatocellular carcinoma (HCC) cells. It was identified that miR-7 was significantly downregulated in tumor tissues compared with adjacent normal tissues. Overexpression of miR-7 inhibited cell proliferative activity, which was partially reversed by miR-7 inhibitor. In addition, overexpression of miR-7 significantly induced an increasen in autophagic activity, and luciferase activity assay and western blot analysis identified that mammalian target of rapamycin (mTOR) was a direct target of miR-7. In addition, inhibition of autophagy by 3-methyladenine resulted in a marked enhancement of the proliferation inhibition effect of miR-7. In conclusion, miR-7 was identified to induce proliferation inhibition and autophagy in HCC cells by targeting mTOR, and inhibition of autophagy may be utilized to enhance the antitumor activity of miR-7.
A Spectral Approach for Sifting Process in Empirical Mode Decomposition

In this paper, we propose an alternative to the algorithmic definition of the sifting process used in the original Huang's empirical mode decomposition (EMD) method. Although it has been proven to be particularly effective in many applications, EMD method has several drawbacks. The major problem with EMD is the lack of theoretical Framework which leads to difficulties for the characterization and evaluation this approach. On top of the mathematical model, there are other concerns with mode mixing and transient phenomena, such as intermittency or pure tones separation. This paper follows a previous published nonlinear diffusion-based filtering to solve the mean-envelope estimation in sifting process. The major improvements made in this present work are a non-iterative resolution scheme for the previously proposed partial differential equation (PDE), a new definition of the stopping function used in the PDE framework, and finally an automatic regularization process based on inverse problem theory to deal with mode mixing or transient detection problem. Obtained results confirm good properties of the new version of the PDE-based sifting process and its usefulness for decomposition of various kinds of data. The efficiency of the method is illustrated on some examples using informative and pathological signals for which standard EMD algorithm fails.
The effect of oral Glucosamine Chondroitin sulfate in the management of knee osteoarthritis

The study was carried out in Tikrit teaching hospital during the period from February 2005 till April 2008. Eighty seven patients presented to the out patient department suffering from knee osteoarthritis. The study aimed to find out the effectiveness of glucoseamine chondroitine sulfate tablets in the management of osteoarthritis. A comparism have been made between 2 groups of patients those treated with glucoseamine chondroitine sulfate and those treated with other modalities. The study showed a vast majority of cases are females aged between 40 – 60 years old and most of them had moderate severity osteoarthritis. The patients' acceptance to the treatment with glucoseamine chondroitine sulfate was poor, so that 36.8% were incompliant, mostly because of the expensive course of treatment. The pain relief and functional improvement was good in a significant bulk of patients using the glucoseamine chondroitine sulfate therapy especially in those with mild to moderate osteoarthritis. Only 8 patients 9.2% of the whole sample developed side effects to glucoseamine chondroitine sulfate, all in form of gastric upset, 6 of them required stopping the medication. The study concludes that glucoseamine chondroitine sulfate is effective in both symptomatic and functional improvement of osteoarthritis whatever the severity.
Health Information–Seeking Behavior of Seniors Who Use the Internet: A Survey

Background The Internet is viewed as an important source for health information and a medium for patient empowerment. However, little is known about how seniors use the Internet in relation to other sources for health information. Objective The aim was to determine which information resources seniors who use the Internet use and trust for health information, which sources are preferred, and which sources are used by seniors for different information needs. Methods Questions from published surveys were selected based on their relevance to the study objectives. The Autonomy Preference Index was used to assess information needs and preferences for involvement in health decisions. Invitation to participate in this online survey was sent to the email list of a local senior organization (298 addresses) in the Netherlands. Results There were 118 respondents with a median age of 72 years (IQR 67-78 years). Health professionals, pharmacists, and the Internet were the most commonly used and trusted sources of health information. Leaflets, television, newspapers, and health magazines were also important sources. Respondents who reported higher use of the Internet also reported higher use of other sources (P<.001). Use of health professionals, pharmacists, leaflets, telephone, television, and radio were not significantly different; use of all other resources was significantly higher in frequent Internet users. When in need of health information, preferred sources were the Internet (46/105, 43.8%), other sources (eg, magazines 38/105, 36.2%), health professionals (18/105, 17.1%), and no information seeking (3/105, 2.8%). Of the 51/107 respondents who indicated that they had sought health information in the last 12 months, 43 sought it after an appointment, 23 were preparing for an appointment, and 20 were deciding if an appointment was needed. The source used varied by the type of information sought. The Internet was used most often for symptoms (27/42, 64%), prognosis (21/31, 68%), and treatment options (23/41, 62%), whereas health professionals were asked for additional information on medications (20/36, 56%), side effects (17/36, 47%), coping (17/31, 55%), practical care (12/14, 86%), and nutrition/exercise (18/30, 60%). Conclusions For these seniors who use the Internet, the Internet was a preferred source of health information. Seniors who report higher use of the Internet also report higher use of other information resources and were also the primary consumers of paper-based resources. Respondents most frequently searched for health information after an appointment rather than to prepare for an appointment. Resources used varied by health topic. Future research should seek to confirm these findings in a general elderly population, investigate how seniors seek and understand information on the Internet, and investigate how to reach seniors who prefer not to use the Internet for health information.
Cytoskeleton of Apicomplexan Parasites

SUMMARY The Apicomplexa are a phylum of diverse obligate intracellular parasites including Plasmodium spp. , the cause of malaria; Toxoplasma gondii and Cryptosporidium parvum, opportunistic pathogens of immunocompromised individuals; and Eimeria spp. and Theileria spp. , parasites of considerable agricultural importance. These protozoan parasites share distinctive morphological features, cytoskeletal organization, and modes of replication, motility, and invasion. This review summarizes our current understanding of the cytoskeletal elements, the properties of cytoskeletal proteins, and the role of the cytoskeleton in polarity, motility, invasion, and replication. We discuss the unusual properties of actin and myosin in the Apicomplexa, the highly stereotyped microtubule populations in apicomplexans, and a network of recently discovered novel intermediate filament-like elements in these parasites.
Design of a substrate integrated waveguide based 1-to-6 non-uniform power divider

In this paper, we have presented an original design of a SIW based planar integrated l-to-6 non-uniform power divider for low sidelobe array antenna applications. This design is more compact and more efficient than many SIW based or microstrip based power dividers. With this design concept, one can design non-uniform power dividers with good amplitude and phase balance. This design can also be easily fabricated and conveniently integrated with other subsystem for a low cost, high performance and integrated system solution.

Antenna Selection and Power Allocation in Massive MIMO

This paper explores the massive multiple-input multiple-output (Ma-MIMO) communication system possessing large number of antennas at the basestation (BS) serving multiple user terminal (UT) in single cell conﬁguration. Due the large number of antennas at the BS, the RF chains used is also increasing with the increase in the total power consumption of the system such as circuit power consumption, ﬁlter, mixer and digital to analog converter power consumption. The main aim of this paper is to reduce the transmit power consumption with the proposed antenna selection and power allocation approach. Initially, the equal power is allocated to users to ﬁnd the optimal number of antenna selection. Then for the number of antennas selected the optimal power allocation is derived to users. An algorithm is proposed to iteratively ﬁnd the antenna selection and power allocation. The simulation is done to evaluate the average data rate and to ﬁnd the optimal transmit power of the system.
A modified orthogonal forward regression least-squares algorithm for system modelling from noisy regressors

In this paper, a modified orthogonal forward regression (OFR) least-squares algorithm is presented for system identification and modelling from noisy regressors. Under the assumption that the energy and signal-to-noise ratio (SNR) of the signals are known or can be estimated, it is shown that unbiased estimates of the Error reduction ratios (ERRs) and the parameters can be obtained in each forward regression step. Examples are provided to illustrate the proposed approach.
Variability of accommodation during steady fixation at various levels of illuminance.

Using the stigmatoscope, the variability of the dioptric power of the eye during steady fixation was measured for four observers over a range of intensities from 2¯. 5 to 3.0 log trolands in one-half logarithmic steps. Two different viewing conditions, (constant and variable size test letters), were studied but no significant difference between them was obtained. There was almost a fourfold decrease in the variability of the settings as the intensity was increased over this range. There was a sharp transition at one troland, suggestive of a discontinuity between scotopic and photopic vision. These changes could be eliminated by cycloplegia of the fixating eye. Essentially the same results were obtained when the refraction of one eye was measured objectively (with a concidence optometer), while the other eye fixated the chart. This latter technique is, however, less valid at the lower intensities because of the tendency to fixate the measuring light of the optometer. The data can be quantitatively described by a theory which postulates that the accommodation is continually fluctuating and that the limits of fluctuation are proportional to threshold ΔI/I.
Model checking race-freeness

With the introduction of highly concurrent systems in standard desktop computers, ensuring correctness of industrial-size concurrent programs is becoming increasingly important. One of the most important standards in use for developing multi-threaded programs is the POSIX Threads standard, commonly known as PThreads. Of particular importance, the analysis of industrial code should, as far as possible, be automatic and not require annotations or other forms of specifications of the code. Model checking has been one of the most successful approaches to program verification during the last two decades. The size and complexity of applications which can be handled have increased rapidly through integration with symbolic techniques. These methods are designed to work on finite (but large) state spaces. This framework fails to deal with several essential aspects of behaviours for multithreaded programs: there is no bound a priori on the number of threads which may arise in a given run of the system; each thread manipulates local variables which often range over unbounded domains; and the system has a dynamic structure in the sense that threads can be created and killed throughout execution of the system. In this paper we concentrate on checking a particular class of properties for concurrent programs, namely safety properties. In particular, we focus on race-freeness, that is, the absence of race conditions (also known as data races) in shared-variable pthreaded programs. We will follow a particular methodology which we have earlier developed for model checking general classes of infinite-state systems [1, 3, 6, 8, 9] and apply a symbolic backward reachability analysis to verify the safety property. Since we construct a model as an over-approximation of the original program, proving the safety property in the model implies that the property also holds in the original system. Surprisingly, it leads to a quite efficient analysis which can be carried out fully automatically.
Physicochemical quality of brown soybean preserve in function of maceration time and ascorbic acid

Although Brazil is the world’s second-largest soybean producer, consumption is low among Brazilians. Researchers have expended great efforts and investments in obtaining cultivars with more acceptable sensory characteristics in order to introduce this leguminous plant into the Brazilian diet. Moreover, the development of soybean cultivars for human food (with free or low-lipoxygenase content, which improves the flavor), health benefits divulgation, and consumer interest has increased. The brown tegument soybean is an alternative for increasing consumption in Brazil, relyingon its similarity to Pinto beans, a typical Brazilian cuisine (Ciabotti et al., 2016).
