Data were collected from correctional officers in Taiwan. Hierarchical regression analysis was used to test the hypotheses. Findings - Results show that work-family conflict has a negative effect on job satisfaction. Perceived supervisor support and internal Practical implications - This study suggests that a supportive leadership style, and a mentoring and training program, among others, may help reduce work-family conflict and increase the job satisfaction of Taiwanese correctional officers. Originality/value - This study contributes to the extant work-family conflict and correctional literature. The moderating effects of perceived supervisor support and internal
Structural features of multiple nifH-like sequences and very biased codon usage in nitrogenase genes of Clostridium pasteurianum

The structural gene (nifH1) encoding the nitrogenase iron protein of Clostridium pasteurianum has been cloned and sequenced. It is located on a 4-kilobase EcoRI fragment (cloned into pBR325) that also contains a portion of nifD and another nifH-like sequence (nifH2). C. pasteurianum nifH1 encodes a polypeptide (273 amino acids) identical to that of the isolated iron protein, indicating that the smaller size of the C. pasteurianum iron protein does not result from posttranslational processing. The 5' flanking region of nifH1 or nifH2 does not contain the nif promoter sequences found in several gram-negative bacteria. Instead, a sequence resembling the Escherichia coli consensus promoter (TTGACA-N17-TATAAT) is present before C. pasteurianum nifH2, and a TATAAT sequence is present before C pasteurianum nifH1. Codon usage in nifH1, nifH2, and nifD (partial) is very biased. A preference for A or U in the third position of the codons is seen. nifH2 could encode a protein of 272 amino acid residues, which differs from the iron protein (nifH1 product) in 23 amino acid residues (8%). Another nifH-like sequence (nifH3) is located on a nonadjacent EcoRI fragment and has been partially sequenced. C. pasteurianum nifH2 and nifH3 may encode proteins having several amino acids that are conserved in other proteins but not in C. pasteurianum iron protein, suggesting a possible role for the multiple nifH-like sequences of C. pasteurianum in the evolution of nifH. Among the nine sequenced iron proteins, only the C. pasteurianum protein lacks a conserved lysine residue which is near the extended C terminus of the other iron proteins. The absence of this positive charge in the C. pasteurianum iron protein might affect the cross-reactivity of the protein in heterologous systems.
Robust Control of a Dynamic Model of an F-16 Aircraft with Improved Damping through Linear Matrix Inequalities

This work presents an application of Linear Matrix Inequalities (LMI) for the robust control of an F-16 aircraft through an algorithm ensuring the damping factor to the closed loop system. The results show that the zero and gain settings are sufficient to ensure robust performance and stability with respect to various operating points. The technique used is the pole placement, which aims to put the system in closed loop poles in a specific region of the complex plane. Test results using a dynamic model of the F-16 aircraft are presented and discussed.
Exploiting Random RGB and Sparse Features for Camera Pose Estimation

We address the problem of estimating camera pose relative to a known scene, given a single RGB image. We extend recent advances in scene coordinate regression forests for camera relocalization in RGB-D images to use RGB features, enabling camera relo-calization from a single RGB image. Furthermore, we integrate random RGB features and sparse feature matching in an efﬁcient and accurate way, broadening the method for fast sports camera calibration in highly dynamic scenes. We evaluate our method on both static, small scale and dynamic, large scale datasets with challenging camera poses. The proposed method is compared with several strong baselines. Experiment results demonstrate the efﬁcacy of our approach, showing superior or on-par performance with the state of the art.
Humanoid robot HRP-2Kai — Improvement of HRP-2 towards disaster response tasks

This paper presents a humanoid robot HRP-2Kai, which is the improvement version of HRP-2 towards disaster response tasks. HRP-2 stands for a humanoid robotics platform-2, which was developed in phase two of the Japanese national project HRP (Humanoid Robotics Project, from 1998FY to 2002FY), while Kai means improvement in Japanese. In a year of the ninth year from releasing HRP-2, the Great East Japan Earthquake shook Japan on March 11, 2011. Since we reflected on that we were not able to deploy our robots for emergency response at that time, we started a study of the disaster response humanoid robots by improving HRP-2. Improvements are presented with its basic specification in this paper.
Expression of a skin cholesterol sulfotransferase, St2b2, is a trigger of epidermal cell differentiation

1. St2b2, a mouse cytosolic sulfotransferase, predominantly catalyses epidermal cholesterol sulfation. St2b2 was found in the basement layer by immunohistochemical analysis of normal mouse skin. The highest expression level was detected in epidermis from 3-day-old mice and then decreased before maturation. There was a good correlation between expression levels of skin St2b2 and a differentiation marker, involucrin. 2. To understand the role of St2b2 in epidermal cell differentiation, recombinant St2b2 was expressed in primary epidermal cells. The expression of St2b2 enhanced the involucrin expression with an increase of cholesterol sulfate. Furthermore, by down-regulation of the St2b2 gene expression, involucrin was decreased in dorsal skin of 1–3-day-old mice by 67% of the control. 3. These results strongly suggest a possibility that St2b2 expression plays a trigger of epidermal cell differentiation by controlling cholesterol sulfate level in the cells.
Stable microreentrant sources as a mechanism of atrial fibrillation in the isolated sheep heart.

BACKGROUND Atrial fibrillation (AF) has traditionally been described as aperiodic or random. Yet, ongoing sources of high-frequency periodic activity have recently been suggested to underlie AF in the sheep heart. Our objective was to use a combination of optical and bipolar electrode recordings to identify sites of periodic activity during AF and elucidate their mechanism. METHODS AND RESULTS AF was induced by rapid pacing in the presence of 0.1 to 0.5 micromol/L acetylcholine in 7 Langendorff-perfused sheep hearts. We used simultaneous optical mapping of the right and left atria (RA and LA) and frequency sampling of optical and bipolar electrode recordings (including a roving electrode) to identify sites having the highest dominant frequency (DF). Rotors were identified from optical recordings, and their rotation period, core area, and perimeter were measured. In all, 35 AF episodes were analyzed. Mean LA and RA DFs were 14.7+/-3.8 and 10.3+/-2.1 Hz, respectively. Spatiotemporal periodicity was seen in the LA during all episodes. In 5 of 7 experiments, a single site having periodic activity at the highest DF was localized. The highest DF was most often (80%) localized to the posterior LA, near or at the pulmonary vein ostium. Rotors (n=14) were localized on the LA. The mean core perimeter and area were 10.4+/-2.8 mm and 3.8+/-2.8 mm(2), respectively. CONCLUSIONS Frequency sampling allows rapid identification of discrete sites of high-frequency periodic activity during AF. Stable microreentrant sources are the most likely underlying mechanism of AF in this model.
Relationship between rates of attending religious services and oral health in Brazilian adolescents.

OBJECTIVES To determine whether there is a relationship between rates of attending religious services and oral health and oral health-related behaviors in Brazilian adolescents. METHODS A cross-sectional study was carried out using clinical examinations and self-applied questionnaires. Sample was 664 15-year-old schoolchildren from public and private schools in the city of Goiânia-GO, Middle-West Brazil. Dependent variables were dental caries (DMFT and DMFS), periodontal condition (Plaque Index and bleeding on probing), perceived importance given to the care of the teeth and oral health-related behaviors (sugar consumption, oral hygiene and pattern of dental attendance). Independent explanatory variable was frequency of attending religious services. Poisson log-linear regressions were used for statistical analysis of the data. RESULTS Oral health status was not associated with attending religious services. Attending religious services was positively associated with oral health behaviors such as pattern of dental attendance for dental checkups and to the importance given to the care of the teeth. These associations remained statistically significant after controlling for sex and social class (P < 0.05). CONCLUSIONS Adolescents' frequency of attending religious services is not associated with their oral health status but is positively related to pattern of dental attendance and perceived importance of care of their teeth.
Those are not the Stories you are Looking For: Using Text Prototypes to Evaluate Game Narratives Early

In game design, evaluation is important to do early and often; however, evaluating game narratives early in development is an open problem. We don't know how the evaluation of a game narrative will be affected when it is experienced outside of the context of the game's mechanics and graphics. In this paper, we test the plausibility of using a text-based narrative prototype, by evaluating player experience and narrative experience in two studies using different game genres. In both studies, we compare the narrative evaluation of low- and high-fidelity graphics, but in study 1 (N=78), we kept interaction mechanics intact, and in study 2 (N=124), we removed game interaction in the text prototype. We observed no significant differences in player experience or narrative engagement in either study, indicating that text-based narrative prototypes could be an effective playtesting tool for game studios to integrate into their development cycle early.
Facing love addiction : giving yourself the power to change the way you love : the love connection to codependence

This is a brilliant new guide to understanding the origins of codependence and the path to recovery by a nationally recognised authority on dependency and addiction. In this fresh new look at codependence, Pia Mellody traces the origins of this illness back to childhood, describing a whole range of emotional, spiritual, intellectual, physical, and sexual abuses. Because of these earlier experiences, codependent adults often lack the skills necessary to lead mature lives and have satisfying relationships. Recovery from codependence comes from clearing up the toxic feelings left over from childhood and learning to reparent oneself by intervening on the adult symptoms of codependence. Central to Mellody's concept is the idea of the precious child that needs healing within each adult. She creates a framework for identifying codependent behavior and describes an effective approach to recovery that includes both therapy and self-help processes. Designed to be used with her new workbook for codependents, "Breaking Free", this is a powerful tool for understanding the nature of codependence.
Neuraminidase Activity: A Biochemical Marker to Distinguish Streptococcus mitis from Streptococcus sanguis

Selected reference and freshly isolated strains of Streptococcus mitis (mitior) and Streptococcus sanguis were assayed for cell-associated neuraminidase activity by their ability to hydrolyze [3H-] sialyllactitol. A cell-associated neuraminidase was detected with S. mitis and S. sanguis serotype II (reclassified as S. mitis) but not with S. sanguis serotypes I and III. Neuraminidase activity of S. mitis correlated with this organism's inability to hydrolyze arginine, aesculin, and few, if any, sugars. The findings indicate that the presence of cell-associated neuraminidase activity is useful for the taxonomic classification of S. mitis.
The L74V Mutation in Human Immunodeficiency Virus Type 1 Reverse Transcriptase Counteracts Enhanced Excision of Zidovudine Monophosphate Associated with Thymidine Analog Resistance Mutations

ABSTRACT Thymidine analog mutations (TAMs) in human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) confer resistance to zidovudine (AZT) by increasing the rate of ATP-dependent phosphorolysis of the terminal nucleotide monophosphate (primer unblocking). By contrast, the L74V mutation, which confers resistance to didanosine, sensitizes HIV-1 to AZT and partially restores AZT susceptibility when present together with one or more TAMs. To compare rates of primer unblocking in RTs carrying different clusters of TAMs and to explore the biochemical mechanism by which L74V affects AZT susceptibility, ATP-mediated rescue of AZT-blocked DNA synthesis was assayed using a series of purified recombinant RTs. Rates of primer unblocking were higher in the 67N/70R/219Q RT than in the 41L/210W/215Y enzyme and were similar to rates observed with an RT carrying six TAMs (41L/67N/70R/210W/215Y/219Q). The presence of 74V in an otherwise wild-type RT reduced the rate of primer unblocking to a degree similar to that observed with the M184V mutation for lamivudine resistance, which also sensitizes HIV-1 to AZT. Introduction of 74V into RTs carrying TAMs partially counteracted the effect of TAMs on the rate of primer unblocking. The effect of 74V was less marked than that of the 184V mutation in the 67N/70R/219Q and 41L/210W/215Y RTs but similar in the RT carrying six TAMs. These results demonstrate that L74V enhances AZT susceptibility by reducing the extent of its removal by ATP-dependent phosphorolysis and provides further evidence for a common mechanism by which mutations conferring resistance to didanosine and lamivudine sensitize HIV-1 to AZT.
Robotic Curiosity and Memory Spatial and Implicit Approaches to Time in CBIM

CBIM is an epigenetic robotics system that uses intrinsic motivation and categorization to learn about its relationship with its environment. CBIM, however, fails to adequately deal with time-dependent relationships; predictions made using CBIM utilize only the current timestep data. In the real world, time is an essential part of interaction. For a system to be able to understand and predict complex patterns and relationships, it requires some way of representing time. In this paper, we explore two methods for applying time to CBIM – one spatial and one implicit – and compare the performance of these two methods and CBIM using several simulated robot tasks.

The paper describes the implementation of the TechConnect support system at Storage Dimensions, a manufacturer of high-availability computer storage system products. TechConnect is a unique IT infrastructure for problem resolution that includes a customer support knowledge base whose structure is dynamically updated based on adaptive learning through customer interactions. The paper assesses the impacts of TechConnect and its value in creating a learning organization. It then draws insights for redesigning knowledge-creating customer support processes for the business conditions of the electronic economy.
Robust spectrum sensing for cognitive radio

This paper studies spectrum sensing in the context of cognitive radio. The proposed detector is robust with respect to disturbing impulses, that are in practice present in many cases in addition to the Gaussian noise. The presence of impulsive noise deteriorates the performance of the detectors derived using Gaussian assumption. In the paper we model the noise explicitly consisting of two components and derive the proper detector. Asymptotic analysis of the detector is then presented and formulae for probabilities of correct detection and fault alarm are derived. The theoretical findings are verified in our simulation study.
Quantitative protein expression and cell surface characteristics of Escherichia coli MG1655 biofilms

Cell surface physicochemical characterization techniques were combined with quantitative changes in protein expression, to investigate the biological and biophysical changes of Escherichia coli MG1655 cells when grown as a biofilm (BIO). The overall surface charge of BIO cells was found to be less negative, highlighting the need for a lower electrophoretic mobility for attachment to occur. Comparison of the chemical functional groups on the cell surface showed similar profiles, with the absorbance intensity higher for proteins and carbohydrates in the BIO cells. Quantitative proteomic analysis demonstrated that 3 proteins were significantly increased, and 9 proteins significantly decreased in abundance, in cells grown as a BIO compared to their planktonic counterparts, with 7 of these total 12 proteins unique to this study. Proteins showing significant increased or decreased abundance include proteins involved in acid resistance, DNA protection and binding and ABC transporters. Further predictive analysis of the metabolic pathways showed an increased abundance of the amino acid metabolism and tricarboxylic acid (TCA) cycle, with a decrease in expression within the pentose phosphate and glycolysis pathways. It is therefore hypothesized that cells grown as a BIO are still energetically viable potentially using amino acids as an indirect carbon backbone source into the TCA cycle.
Divergence population genetic analysis of hybridization between rhesus and cynomolgus macaques

The geographic ranges of rhesus (Macaca mulatta) and cynomolgus (M. fascicularis) macaques adjoin in Indochina where they appear to hybridize. We used published and newly generated DNA sequences from 19 loci spanning ~20 kb to test whether introgression has occurred between these macaque species. We studied introgression at the level of nuclear DNA and distinguished between incomplete lineage sorting of ancestral polymorphisms or interspecific gene flow. We implemented a divergence population genetics approach by fitting our data to an isolation model implemented in the software IMa. The model that posits no gene flow from the rhesus into the cynomolgus macaque was rejected (P = 1.99 × 10−8). Gene flow in this direction was estimated as 2Nm~1.2, while gene flow in the reverse direction was nonsignificantly different from zero (P = 0.16). The divergence time between species was estimated as ~1.3 million years. Balancing selection, a special case of incomplete sorting, was taken into consideration, as well as potential crossbreeding in captivity. Parameter estimates varied between analyses of subsets of data, although we still rejected isolation models. Geographic sampling of the data, where samples of cynomolgus macaques derived from Indochina were excluded, revealed a lost signature of gene flow, indicating that interspecific gene flow is restricted to mainland Indochina. Our results, in conjunction with those by others, justify future detailed analyses into the genetics of reproductive barriers and reticulate evolution in these two genome‐enabled primates. Future studies of the natural hybridization between rhesus and cynomolgus macaques would expand the repertoire of systems available for speciation studies in primates.
Coupled electro-thermal Simulations of single event burnout in power diodes

Power diodes may undergo destructive failures when they are struck by high-energy particles during the off state (high reverse-bias voltage). This paper describes the failure mechanism using a coupled electro-thermal model. The specific case of a 3500-V diode is considered and it is shown that the temperatures reached when high voltages are applied are sufficient to cause damage to the constituent materials of the diode. The voltages at which failure occurs (e.g., 2700 V for a 17-MeV carbon ion) are consistent with previously reported data. The simulation results indicate that the catastrophic failures result from local heating caused by avalanche multiplication of ion-generated carriers.
Efficient photometric stereo on glossy surfaces with wide specular lobes

This paper presents a new photometric stereo method aiming to efficiently estimate BRDF and reconstruct glossy surfaces. Rough specular surfaces exhibit wide specular lobes under different lightnings. They are ubiquitous and usually bring difficulties to both specular pixel removal and surface normal recovery. In our approach, we do not apply unreliable highlight separation and specularity estimation. Instead, an important visual cue, i.e. the cast shadow silhouette of the object, is employed to optimally recover global BRDF parameters. These parameter estimates are then taken into a reflectance model for robustly computing the surface normals and other local parameters using an iterative optimization. Within the unified framework, our method can also be used to reconstruct object surfaces assembled with multiple materials.
The clinical and CT imaging features of metanephric adenoma

Background Patients with metanephric adenoma have a good prognosis after undergoing total nephrectomy or local resection with kidney preservation. Accurate diagnosing is important for guiding clinical treatment. Only few previous case reports have been found focusing on the imaging findings of metanephric adenoma. Purpose To evaluate the multislice computed tomography (MSCT) imaging characteristics of metanephric adenoma. Material and Methods The imaging findings in eight patients with metanephric adenoma were studied retrospectively. MSCT was undertaken to investigate tumor location, size, attenuation, cystic or solid appearance, calciﬁcation, capsule sign, and enhancement pattern. Results Tumors (mean diameter, 3.3 ± 1.0 cm) were solitary (8/8), solid (7/8) with cystic components (2/8), no calcifications (7/8), had a poorly-deﬁned margin (8/8), were centered in the renal medulla (7/8), compressed the renal pelvis (3/8), and none had retroperitoneal lymph node metastasis. The attenuation of metanephric adenoma tumors was less or equal compared to the renal cortex or medulla on unenhanced CT (30.6 ± 2.6 vs. 36.3 ± 4.6 vs. 33.2 ± 3.9, P > 0.05), while tumor enhancement after administration of an contrast agent was lower than that of normal renal cortex and medulla during all phases (P < 0.05). Conclusion Metanephric adenoma tends to be a solitary, poorly defined margin, isodense or hypodense mass arising from the renal medulla with enhancement less than the cortex and medulla during all phases.
