The Psychometric Properties of Attentional Control Scale and Its Relationship with Symptoms of Anxiety and Depression: A Study on Iranian Population

Objectives: The attentional control scale is a self- report questionnaire that assesses individual differences in attentional control. Despite its extensive use, the psychometric properties of the Persian version of the ACS are not well understood. Thus, the present study aimed at investigating the psychometric properties of the attentional control scale and its relationship with symptoms of anxiety and depression in Iranian population. Method: Using quota sampling, we asked a community sample of 524 to respond to Attentional Control Scale, mindfulness, emotion regulation, social anxiety, depression, generalized anxiety, worry, and rumination. SPSS (Version 23) was used for data analysis. Results: Exploratory factor analysis yielded 2 factors of focusing and shifting, which accounted for 30.93% of the total variance. The results of convergent validity revealed that reappraisal, as an emotion regulation strategy and mindfulness facets, had a positive relationship with focusing, shifting, and the total score of the attentional control scale. Furthermore, worry, rumination, depression, generalized anxiety, and social anxiety symptoms all had negative relationships with focusing, rumination, and the total score of the attentional control scale. In addition, the results of incremental validity revealed that focusing, not shifting, uniquely predicted depression and generalized anxiety symptoms. Furthermore, both focusing and shifting uniquely predicted social anxiety symptoms. Test- retest reliability of focusing and shifting was 0.80 and 0. 76, respectively. Conclusion: Attentional control scale has been demonstrated to have acceptable validity and reliability in Iranian population. However, further studies are needed to evaluate other aspects of the ACS like CFA.
Adaptive Web Prefetching Scheme using Link Anchor Information

Web prefetching provides an effective mechanism to mitigate the user perceived latency when accessing the web pages. The content of web pages provide useful information for generating the predictions, which are used to prefetch the web objects for satisfying the user‟s future requests. In this paper, we propose fuzzy logic based web prefetching scheme that generates effective predictions for prefetching the web objects. Predictions are generated based on the anchor text information associated with hyperlinks in a web page. Based on the user‟s browsing pattern in each session, prediction engine dynamically computes the value and generates the list of predictions. The prefetched web objects are effectively utilized when user browses the web pages for information related to specific topic of interest. In long duration browsing sessions, useful predictions are generated to efficiently minimize the user perceived latency. The proposed scheme is compared with existing prefetching algorithms and the results indicate that the new scheme achieves improved cache-hit rate and precision accuracy.

Serum hepcidin levels and iron parameters in children with iron deficiency

Background Iron deficiency (ID) and iron deficiency anemia (IDA) are common nutritional disorders in children. Hepcidin, a peptide hormone produced in the liver, is a central regulator of systemic iron metabolism. We evaluated whether serum hepcidin levels can diagnose ID in children. Methods Sera from 59 children (23 males and 36 females; 5 months to 17 years) were analyzed for hepcidin-25 by ELISA. Patients were classified according to hemoglobin level and iron parameters as: IDA, (N=17), ID (N=18), and control (N=24). Results Serum hepcidin, ferritin, soluble transferrin receptor (sTfR), transferrin saturation, and hemoglobin levels differed significantly between groups (P<0.0001). Serum hepcidin and ferritin levels (mean±SD) were 2.01±2.30 and 7.00±7.86, 7.72±8.03 and 29.35±24.01, 16.71±14.74 and 46.40±43.57 ng/mL in the IDA, ID, and control groups, respectively. The area under the receiver operating characteristic curve for serum hepcidin as a predictor of ID was 0.852 (95% CI, 0.755-0.950). Hepcidin ≤6.895 ng/mL had a sensitivity of 79.2% and specificity of 82.8% for the diagnosis of ID. Serum hepcidin levels were significantly correlated with ferritin, transferrin saturation, and hemoglobin levels and significantly negatively correlated with sTfR level and total iron binding capacity (P<0.0001). Conclusion Serum hepcidin levels are significantly associated with iron status and can be a useful indicator of ID. Further studies are necessary to validate these findings and determine a reliable cutoff value in children.
On the Interdependence of Routing and Data Compression in Multi-Hop Sensor Networks

Abstract We consider a problem of broadcast communication in sensor networks, in which samples of a random field are collected at each node, and the goal is for all nodes to obtain an estimate of the entire field within a prescribed distortion value. The main idea we explore in this paper is that of jointly compressing the data generated by different nodes as this information travels over multiple hops, to eliminate correlations in the representation of the sampled field. Our main contributions are: (a) we obtain, using simple network flow concepts, conditions on the rate/distortion function of the random field, so as to guarantee that any node can obtain the measurements collected at every other node in the network, quantized to within any prescribed distortion value; and (b) we construct a large class of physically-motivated stochastic models for sensor data, for which we are able to prove that the joint rate/distortion function of all the data generated by the whole network grows slower than the bounds found in (a). A truly novel aspect of our work is the tight coupling between routing and source coding, explicitly formulated in a simple and analytically tractable model – to the best of our knowledge, this connection had not been studied before.
Pericardial effusion with cardiac tamponade caused by a central venous catheter in a very low birth weight infant

With more and more extreme premature and very low-birth weight babies being resuscitated, umbilical central venous catheterisation is now being used more frequently in neonatal intensive care. One of the life-threatening complications is pericardial effusion and cardiac tamponade; however, it is potentially reversible when it is caught in time. The authors present a case of cardiac tamponade following umbilical venous catheterisation in a neonate. The patient was diagnosed at the appropriate time by echocardiography and urgent pericardiocentesis proved lifesaving.
Ly49 Receptors: Innate and Adaptive Immune Paradigms

The Ly49 receptors are type II C-type lectin-like membrane glycoproteins encoded by a family of highly polymorphic and polygenic genes within the mouse natural killer (NK) gene complex. This gene family is designated Klra, and includes genes that encode both inhibitory and activating Ly49 receptors in mice. Ly49 receptors recognize class I major histocompatibility complex-I (MHC-I) and MHC-I-like proteins on normal as well as altered cells. Their functional homologs in humans are the killer cell immunoglobulin-like receptors, which recognize HLA class I molecules as ligands. Classically, Ly49 receptors are described as being expressed on both the developing and mature NK cells. The inhibitory Ly49 receptors are involved in NK cell education, a process in which NK cells acquire function and tolerance toward cells that express “self-MHC-I. ” On the other hand, the activating Ly49 receptors recognize altered cells expressing activating ligands. New evidence shows a broader Ly49 expression pattern on both innate and adaptive immune cells. Ly49 receptors have been described on multiple NK cell subsets, such as uterine NK and memory NK cells, as well as NKT cells, dendritic cells, plasmacytoid dendritic cells, macrophages, neutrophils, and cells of the adaptive immune system, such as activated T cells and regulatory CD8+ T cells. In this review, we discuss the expression pattern and proposed functions of Ly49 receptors on various immune cells and their contribution to immunity.
Forking Genetic Algorithm with Blocking and Shrinking Modes (fGA)

There are many GA-hard problems that are difficult to solve by the traditional GAs such as problems with multi-modal and deceptive evaluation functions [4] [15]. Many kinds of modified GAs that are aimed to solve these problems are p r o p o s e d s u c h a s C H C [ 2 ] , m G A [ 5 ] , GENITOR[13] and Niche Method[4]. In this paper, we propose a new type of GA, that is, the forking Genetic Algorithm (fGA). The fGA is designed to solve such problems as have multi-modal evaluation functions with many local optimal points. This GA evolves multi-populations. In conventional GAs with multi-populations [1] [6] [10], each population is independently evolved in the same genetic operations. They maintain and enrich diversity gained by genetic drift through immigration of individuals between populations [6] [10]. The distinguishing feature of the fGA is that it has one parent population with a blocking mode and one or more child populations with a shrinking mode as a result of population forking. Each population takes a different role in optimizing tasks. That is, each population is responsible for searching for nonoverlapping sub-areas in the search space. Genetic operators of the fGA, the process of the population forking and empirical results are described in the following sections.
Successful aging in the United States: prevalence estimates from a national sample of older adults.

OBJECTIVES To estimate the prevalence of successful aging in the United States, with the broad aim of contributing to the dialogue on Rowe and Kahn's concept of successful aging. METHODS Using data from the Health and Retirement Study, the prevalence of successful aging was calculated for adults aged 65 years and older at four time points: 1998, 2000, 2002, and 2004. Successful aging was operationalized in accordance with Rowe and Kahn's definition, which encompasses disease and disability, cognitive and physical functioning, social connections, and productive activities. RESULTS No greater than 11.9% of older adults were aging "successfully" in any year. The adjusted odds of successful aging were generally lower for those of advanced age, male gender, and lower socioeconomic status. Between 1998 and 2004, the odds of successful aging declined by 25%, after accounting for demographic changes in the older population. DISCUSSION Few older adults meet the criteria put forth in Rowe and Kahn's definition of successful aging, suggesting the need for modification if the concept is to be used for broad public health purposes. Disparities in successful aging were evident for socially defined subgroups, highlighting the importance of structural factors in enabling successful aging.
Impact modifiers: Providing a boost to impact performance

Some of the additives used in plastics formulations, such as flame retardants, fillers, heat distortion temperature modifiers, and pigments, can have a detrimental effect on the impact resistance of the material. Impact modifiers can sometimes be used to “correct” for the detrimental effects of these additives by boosting the impact performance of the material. The functions of core/shell impact modifiers in improving impact resistance are described. Some general guidelines for selecting impact modifier products are discussed.
Novel Method to Detect and Characterize 18F-FDG Infiltration at the Injection Site: A Single-Institution Experience

A novel quality control and quality assurance device provides time–activity curves that can identify and characterize PET/CT radiotracer infiltration at the injection site during the uptake phase. The purpose of this study was to compare rates of infiltration detected by the device with rates detected by physicians. We also assessed the value of using the device to improve injection results in our center. Methods: 109 subjects consented to the study. All had passive device sensors applied to their skin near the injection site and mirrored on the contralateral arm during the entire uptake period. Nuclear medicine physicians reviewed standard images for the presence of dose infiltration. Sensor-generated time–activity curves were independently examined and then compared with the physician reports. Injection data captured by the software were analyzed, and the results were provided to the technologists. Improvement measures were implemented, and rates were remeasured. Results: Physician review of the initial 40 head-to-toe field-of-view images identified 15 cases (38%) of dose infiltration (9 minor, 5 moderate, and 1 significant). Sensor time–activity curves on these 40 cases independently identified 22 cases (55%) of dose infiltration (16 minor, 5 moderate, and 1 significant). After the time–activity curve results and the contributing factor analysis were shared with technologists, injection techniques were modified and an additional 69 cases were studied. Of these, physician review identified 17 cases (25%) of infiltration (13 minor, 3 moderate, and 1 significant), a 34% decline. Sensor time–activity curves identified 4 cases (6%) of infiltration (2 minor and 2 moderate), an 89% decline. Conclusion: The device provides valuable quality control information for each subject. Time–activity curves can further characterize visible infiltration. Even when the injection site was out of the field of view, the time–activity curves could still detect and characterize infiltration. Our initial experience showed that the quality assurance information obtained from the device helped reduce the rate and severity of infiltration. The device revealed site-specific contributing factors that helped nuclear medicine physicians and technologists customize their quality improvement efforts to these site-specific issues. Reducing infiltration can improve image quality and SUV quantification, as well as the ability to minimize variability in a site’s PET/CT results.
Caveolar domain organization and trafficking is regulated by Abl kinases and mDia1

Summary The biology of caveolin-1 (Cav1)/caveolae is intimately linked to actin dynamics and adhesion receptors. Caveolar domains are organized in hierarchical levels of complexity from curved or flattened caveolae to large, higher-order caveolar rosettes. We report that stress fibers controlled by Abl kinases and mDia1 determine the level of caveolar domain organization, which conditions the subsequent inward trafficking of caveolar domains induced upon loss of cell adhesion from the extracellular matrix. Abl-deficient cells have fewer stress fibers, a smaller pool of stress-fiber co-aligned Cav1 and increased clustering of Cav1/caveolae at the cell surface. Defective caveolar linkage to stress fibers prevents the formation of big caveolar rosettes upon loss of cell adhesion, correlating with a lack of inward trafficking. Live imaging of stress fibers and Cav1 showed that the actin-linked Cav1 pool loses its spatial organization in the absence of actin polymerization and is dragged and clustered by depolymerizing filaments. We identified mDia1 as the actin polymerization regulator downstream of Abl kinases that controls the stress-fiber-linked Cav1 pool. mDia1 knockdown results in Cav1/caveolae clustering and defective inward trafficking upon loss of cell adhesion. By contrast, cell elongation imposed by the excess of stress fibers induced by active mDia1 flattens caveolae. Furthermore, active mDia1 rescues the actin co-aligned Cav1 pool and Cav1 inward trafficking upon loss of adhesion in Abl-deficient cells. Thus, caveolar domain organization and trafficking are tightly coupled to adhesive and stress fiber regulatory pathways.
Increased expression of putative cancer stem cell markers in the bone marrow of prostate cancer patients is associated with bone metastasis progression

The number of cells positive for the α‐6 and α‐2 integrin subunits and the c‐Met receptor in primary tumors and bone biopsies from prostate cancer patients has been correlated with metastasis and disease progression. The objective of this study was to quantify disseminated tumour cells present in bone marrow in prostate cancer patients using specific markers and determine their correlation with metastasis and survival.
On measure and Hausdorff dimension of Julia sets for holomorphic Collet--Eckmann maps

Let $f:\bar\bold C\to\bar\bold C$ be a rational map on the Riemann sphere , such that for every $f$-critical point $c\in J$ which forward trajectory does not contain any other critical point, $|(f^n)'(f(c))|$ grows exponentially fast (Collet--Eckmann condition), there are no parabolic periodic points, and else such that Julia set is not the whole sphere. Then smooth (Riemann) measure of the Julia set is 0. For $f$ satisfying additionally Masato Tsujii's condition that the average distance of $f^n(c)$ from the set of critical points is not too small, we prove that Hausdorff dimension of Julia set is less than 2. This is the case for $f(z)=z^2+c$ with $c$ real, $0\in J$, for a positive line measure set of parameters $c$.
Sense of alexithymia in patients with anxiety disorders comorbid with recurrent urticaria

Aim Alexithymia is associated with limited cognitive processing of emotions by an individual suffering from recurrent urticaria and alexithymia and makes them focus on somatic manifestations of emotional arousal and on poorly controlled compulsive reactions to negative stimulation. Alexithymia is considered to be a personality trait, which, along with other factors, predisposes individuals toward developing somatic diseases. The aim of the study was to assess the measurement of alexithymic features in patients with recurrent urticaria and to assess the types of concurrent anxiety disorders and overall anxiety level. Methods In order to diagnose clinical anxiety symptoms in patients, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition and the Hamilton Anxiety Rating Scale were applied. Alexithymic features were measured by means of a shortened version of the Toronto Alexithymia Scale, characterized by high discrimination power, internal coherence, and reliability. Results According to the Toronto Alexithymia Scale results, the greatest contributing factor was “inability to differentiate between feelings and bodily sensations”. This was observed in both males and females. Most frequently, the patients were found to suffer from generalized anxiety disorder and social phobia. Conclusion Alexithymia may result from the difficulty associated with expressing emotions caused by anxiety disorders. Undergoing treatment for anxiety disorders may contribute to reduced exacerbation of urticaria.
Break-induced replication: A review and an example in budding yeast

Break-induced replication (BIR) is a nonreciprocal recombination-dependent replication process that is an effective mechanism to repair a broken chromosome. We review key roles played by BIR in maintaining genome integrity, including restarting DNA replication at broken replication forks and maintaining telomeres in the absence of telomerase. Previous studies suggested that gene targeting does not occur by simple crossings-over between ends of the linearized transforming fragment and the target chromosome, but involves extensive new DNA synthesis resembling BIR. We examined gene targeting in Saccharomyces cerevisiae where only one end of the transformed DNA has homology to chromosomal sequences. Linearized, centromere-containing plasmid DNA with the 5′ end of the LEU2 gene at one end was transformed into a strain in which the 5′ end of LEU2 was replaced by ADE1, preventing simple homologous gene replacement to become Leu2+. Ade1+ Leu2+ transformants were recovered in which the entire LEU2 gene and as much as 7 kb of additional sequences were found on the plasmid, joined by microhomologies characteristic of nonhomologous end-joining (NHEJ). In other experiments, cells were transformed with DNA fragments lacking an ARS and homologous to only 50 bp of ADE2 added to the ends of a URA3 gene. Autonomously replicating circles were recovered, containing URA3 and as much as 8 kb of ADE2-adjacent sequences, including a nearby ARS, copied from chromosomal DNA. Thus, the end of a linearized DNA fragment can initiate new DNA synthesis by BIR in which the newly synthesized DNA is displaced and subsequently forms circles by NHEJ.
Inkjet printing of nanosized silver colloids

A water-based conducting ink, composed of well dispersed nano-silver particles, has been successfully inkjet printed using an ordinary commercial printer. The silver colloids with diameter around 50 nm were dispersed in a water and diethylene glycol cosolvent system. The 25 wt% silver ink had a viscosity of about 7.4 cP and surface tension of 33.5 dyn cm−1 at 20 °C, which is appropriate for printing jobs. Continuous and smooth lines of 130 µm width could be printed on ordinary glass substrates using an Epson R210 printer. After baking at 260 °C for 3 min, these lines exhibited a resistivity of 1.6 × 10−5 Ω cm, which could serve as conducting lines for electronic applications.

Memristor Circuits: Flux—Charge Analysis Method

Memristor-based circuits are widely exploited to realize analog and/or digital systems for a broad scope of applications (e.g., amplifiers, filters, oscillators, logic gates, and memristor as synapses). A systematic methodology is necessary to understand complex nonlinear phenomena emerging in memristor circuits. The manuscript introduces a comprehensive analysis method of memristor circuits in the flux-charge (φ, q)-domain. The proposed method relies on Kirchhoff Flux and Charge Laws and constitutive relations of circuit elements in terms of incremental flux and charge. The main advantages (over the approaches in the voltage-current (v, i)-domain) of the formulation of circuit equations in the (φ, q)-domain are: a) a simplified analysis of nonlinear dynamics and bifurcations by means of a smaller set of ODEs; b) a clear understanding of the influence of initial conditions. The straightforward application of the proposed method provides a full portrait of the nonlinear dynamics of the simplest memristor circuit made of one memristor connected to a capacitor. In addition, the concept of invariant manifolds permits to clarify how initial conditions give rise to bifurcations without parameters.
