Assembly maintainability study with motion planning

Maintainability is an important issue in design where the accessibility of certain parts is determined for routine maintenance. In the past its study has been largely manual and labor intensive. Either by using physical mockup or computer animation with CAD models of a design, the task relies on a human to provide an access path for the part. In this paper, the authors present an automated approach to replace this manual process. By applying results from and developing extensions to research in motion planning and other fields, the authors demonstrate that an automated maintainability study system is feasible. The authors describe general extensions needed to adapt robotic motion planning techniques in maintainability studies. The authors show results from applying such a system to two classes of industrial application problems.
The static stress change triggering model: Constraints from two southern California aftershock sequences

Static stress change has been proposed as a mechanism of earthquake triggering. We quantitatively evaluate this model for the apparent triggering of aftershocks by the 1992 M_W 7.3 Landers and 1994 M_W 6.7 Northridge earthquakes. Specifically, we test whether the fraction of aftershocks consistent with static stress change triggering is greater than the fraction of random events which would appear consistent by chance. Although static stress changes appear useful in explaining the triggering of some aftershocks, the model's capability to explain aftershock occurrence varies significantly between sequences. The model works well for Landers aftershocks. Approximately 85% of events between 5 and 75 km distance from the mainshock fault plane are consistent with static stress change triggering, compared to ∼50% of random events. The minimum distance is probably controlled by limitations of the modeling, while the maximum distance may be because static stress changes of <0.01 MPa trigger too few events to be detected. The static stress change triggering model, however, can not explain the first month of the Northridge aftershock sequence significantly better than it explains a set of random events. The difference between the Landers and Northridge sequences may result from differences in fault strength, with static stress changes being a more significant fraction of the failure stress of weak Landers-area faults. Tectonic regime, regional stress levels, and fault strength may need to be incorporated into the static stress change triggering model before it can be used reliably for seismic hazard assessment.
Protein tyrosine phosphatase, PTP1B, expression and activity in rat corneal endothelial cells

Purpose The current studies were conducted to determine whether the protein tyrosine phosphatase, PTP1B, plays a role in regulating epidermal growth factor receptor (EGFR) Tyr992 phosphorylation and cell cycle entry in rat corneal endothelial cells. Methods Corneas were obtained from male Sprague-Dawley rats. PTP1B mRNA and protein expression were compared in confluent and subconfluent cells by RT-PCR and western blots. Immunocytochemistry was used to determine the subcellular localization of both PTP1B and EGFR following epidermal growth factor (EGF) stimulation. Western blots were used to analyze the time-dependent effect of EGF on phosphorylation of EGFR Tyr992 plus or minus CinnGEL 2Me, an inhibitor of PTP1B activity. The effect of PTP1B inhibition on cell cycle entry was determined by calculating the percent of Ki67-positive cells following EGF treatment. Results PTP1B mRNA expression was similar in confluent and subconfluent cells, but PTP1B protein was expressed at 3 fold higher levels in subconfluent cells. Positive staining for PTP1B was localized in vesicular structures below the plasma membrane. EGFR staining was located at cell-cell borders in untreated endothelium, but was mainly cytoplasmic by 15 min after EGF treatment. In control cultures, phosphorylation of EGFR Tyr992 peaked by 5 min following EGF stimulation and rapidly decreased to basal levels by 30 min. In cultures pretreated with CinnGEL 2Me, Tyr992 phosphorylation peaked 2 min following EGF addition and was consistently sustained at a higher level than controls until 60 min after treatment. By 18 h following EGF treatment, cultures pretreated with CinnGEL 2Me exhibited a 1.7 fold increase in the number of Ki67-positive cells compared with control cultures. Conclusions Comparison of PTP1B mRNA and protein levels indicates that PTP1B expression is regulated mainly at the protein level and is higher in subconfluent cells. PTP1B was located in vesicles below the plasma membrane. The fact that EGFR is internalized in response to EGF stimulation suggests that it could interact with and be regulated by PTP1B. The ability of PTP1B inhibitor to sustain EGFR Tyr992 phosphorylation and increase the number of Ki67-positive cells indicates that PTP1B plays a role in the negative regulation of EGF-induced signaling and helps suppress cell cycle entry.
Representing Self-knowledge for Introspection about Memory Search

This position paper sketches a framework for modeling introspective reasoning and discusses the relevance of that framework for modeling introspective reasoning about memory search. It argues that effective and flexible memory processing in rich memories should be built on five types of explicitly represented self-knowledge: knowledge about information needs, relationships between different types of information, expectations for the actual behavior of the information search process, desires for its ideal behavior, and representations of how those expectations and desires relate to its actual performance. This approach to modeling memory search is both an illustration of general principles for modeling introspective reasoning and a step towards addressing the problem of how a reasoner— human or machine—can acquire knowledge about the properties of its own knowledge base.
How to Select a Good Alternate Path in Large Peer-to-Peer Systems?

When multiple paths are available between communicating hosts, application quality can be improved by switching among them to always use the best one. The key to such an approach is the availability of diverse paths, i.e., paths with uncorrelated performance. A promising approach for implementing the necessary path diversity is to leverage the capabilities of peer-to-peer systems. Peer-to-peer systems are attractive not only because their many participating nodes can act as relays for others, and therefore offer a large number of different alternate paths, but also because their distributed operation can facilitate the deployment of the required functionality. However, these advantages come at a cost, as the sheer number of alternate path choices they offer creates its own challenge. In particular, because not all choices are equally good, it is necessary to develop mechanisms for easily and rapidly identifying relay nodes that yield good alternate paths. This paper is about the formulation and evaluation of such mechanisms in the context of large peerto-peer systems. Our goal is to devise techniques that for any given destination allow nodes to quickly select a candidate relay node with as small a cost as possible in terms of how much information they need to store or process. We combine several heuristics that rely only on local routing information, and validate the resulting solution by comparing it to a number of benchmark alternatives. This comparison is carried out using both topology data from RouteView/RIPE and PlanetLab nodes, and through measurements across a large set of PlanetLab nodes.
Responding to the needs of people with learning disabilities who have been raped: co-production in action

Purpose – The purpose of this paper is to discuss a project that explored why mainstream rape support services are still failing to meet the needs of women with learning disabilities. Principles of co-production and action learning enabled a group of women, including women with learning disabilities, to share knowledge and skills and develop easy-read information leaflets. Design/methodology/approach – The project included representatives from a university, a third sector organisation and a rape crisis centre. Action learning methods were used to bring together a broad range of experience and expertise. The project was co-led by a woman with a learning disability and a lecturer in social work with people with learning disabilities. Findings – Three organisations had been toiling with a similar issue, that of responses to women with learning disabilities who had been raped. All had previously examined the problem from their own perspectives. An action learning process enabled them to explore the issues from a range of experiences, sharing knowledge and expertise and enabling them to begin to develop better service responses. While co-production may highlight competing priorities in and between organisations, it can also provide the means of managing these tensions. Social implications – The project demonstrated the importance of co-production. Working together led to a shared understanding of the barriers experienced by women with learning disabilities who experience rape and of the challenges faced by workers who aim to support them. This shared understanding enabled the action learning set to develop bespoke training and literature. Originality/value – The project demonstrates the importance of working with people with learning disabilities in order to develop services that truly meet their needs.
More Than Just Error Correction

Drawing on the second phase of a 2-year study of students' linguistic and compositional processes, this article describes students' reflections on their online revision processes, those revisions made during the process of translating thoughts into written text. The data collected were from classroom observation and post hoc interviews with 34 students, who were observed during a writing task in the English classrooms and interviewed subsequently to elicit their reflections and understandings of their own revising processes. The analysis indicates that students tend to conceptualize revision as a macro-strategy and as a task that is predominantly undertaken as a posttextual production reviewing activity. It also indicates that students engage in multiple revising activities during writing, including many revisions that are not concerned with simple matters of surface accuracy, and many students are able to talk about these perceptively and with insight.

In recent years, research has been done in working life is an important concept of emotional labor. The purpose of the present study is to investigate the reliability and validity of the Turkish version of the Emotional Labour Scale which was developed and later revised by Brotheridge and Lee (2003). This study is carried out with 301 service sector employees within the area of city Bursa . The validity of emotional labor scale was evaluated for two type’s validity; as a scope and construct validity. In the study to determine the reliability of the scale, Cronbach Alpha reliability coefficient is calculated. As a result of the analysis, 70.02 % of the total variance explaining the 9 items and 3 sub-dimensions consisting of a measuring instrument were obtained and sub-dimensions of the constituents of the original scale substances overlaps each other’s. As a result, best fit indices are obtained and after confirmatory factor analysis, all factor loadings were found statistically significant. Cronbach's alpha values of the dimensions of the scale were found in acceptable limits within the ranged between . 74 and . 81. The Turkish form of Emotional Labour Scale was found to be valid and reliable. This instrument can be used by the researchers in the studies that will be conducted in Turkey.
Increased CD11b neutrophil expression in Budd–Chiari syndrome or portal vein thrombosis secondary to polycythaemia vera

Budd–Chiari syndrome and portal vein thrombosis (BCS/PVT) are frequently associated with polycythaemia vera (PV). In an attempt to elucidate the mechanisms of BCS/PVT secondary to PV (T‐PV), CD11b neutrophil expression, neutrophil oxidative burst and platelet–neutrophil complexes (PNC) were assessed in 17 such patients. Three groups served as controls: BCS/PVT not secondary to PV (T‐nPV; n = 20), PV without thrombosis (PV‐nT; n = 16), and healthy controls (HC; n = 20). Baseline CD11b expression (in mean fluorescence intensity units) was 101 [95% confidence interval (CI): 79–128] in T‐PV patients, versus 25 (95% CI: 18–35) in T‐nPV, 59 (95% CI: 43–80) in PV‐nT, and 34 (95% CI: 25–48) in HC (P < 0·001). After N‐formyl‐L‐methionyl‐L‐leucyl‐L‐phenylalanine activation, T‐PV patients also showed higher CD11b values: 190 (95% CI: 151–238), versus 55 (95% CI: 41–72) in T‐nPV, 111 (95% CI: 81–153) in PV‐nT, and 77 (95% CI: 63–95) in HC (P < 0·001). In BCS/PVT, CD11b neutrophil expression had 90% specificity and 100% sensitivity for the association with PV. Finally, PV patients had higher oxidative burst and PNC than T‐nPV patients or HC (P < 0·05). These results support a role for neutrophils in BCS/PVT secondary to PV and indicate that neutrophil CD11b expression could be of use for PV screening in BCS/PVT patients.
Quality of Life in Women with Polycystic Ovary Syndrome after a Program of Resistance Exercise Training

Abstract Purpose Aerobic exercises may improve quality of life (QoL) in women with polycystic ovary syndrome (PCOS). However, there is no data on the effect of resistance exercise training (RET) programs on the QoL of women with PCOS. Thus, this study aimed to assess the effect of a 16-week RET program on QoL in PCOS women. Methods This 16-week case-control study enrolled 43 women with PCOS (PCOS group, PCOSG) and 51 healthy pre-menopausal controls aged 18 to 37 years (control group, CG). All women underwent a supervised RET program for 16 weeks, and were evaluated in two different occasions: week-0 (baseline), and week-16 (after RET). Quality of life was assessed using the 36-Item Short Form Health Survey (SF-36). Results Testosterone reduced significantly in both groups after RET (p < 0.01). The PCOSG had improvements in functional capacity at week-16 relative to week-0 (p = 0.02). The CG had significant improvements in vitality, social aspects, and mental health at week-16 relative to week-0 (p ≤ 0.01). There was a weak correlation between social aspects of the SF-36 domain and testosterone levels in PCOS women. Conclusion A 16-week RET program modestly improved QoL in women with PCOS.
A multi-Gbps unrolled hardware list decoder for a systematic polar code

Polar codes are a new class of block codes with an explicit construction that provably achieve the capacity of various communications channels, even with the low-complexity successive-cancellation (SC) decoding algorithm. Yet, the more complex successive-cancellation list (SCL) decoding algorithm is gathering more attention lately as it significantly improves the error-correction performance of short-to moderate-length polar codes, especially when they are concatenated with a cyclic redundancy check code. However, as SCL decoding explores several decoding paths, existing hardware implementations tend to be significantly slower than SC-based decoders. In this paper, we show how the unrolling technique, which has already been used in the context of SC decoding, can be adapted to SCL decoding yielding a multi-Gbps SCL-based polar decoder with an error-correction performance that is competitive when compared to an LDPC code of similar length and rate. Post-place-and-route ASIC results for 28 nm CMOS are provided showing that this decoder can sustain a throughput greater than 10 Gbps at 468 MHz with an energy efficiency of 7.25 pJ/bit.
Integration of flutist gesture recognition and beat tracking for human-robot ensemble

A novel human-robot trio-ensemble system with a human flutist, a human drummer and a robot-thereminist is presented. The participants of the ensemble play music in a score-based way and simultaneously, which has only been achieved independently. In our ensemble, both auditory and visual cues are used to synchronize the participants’ performances. The ensemble begins with the flutist’s start gesture. The participants of the ensemble play in accordance with the drummer’s playing speed, then, they finish playing at the flutist’s end gesture. The ensemble system is developed by integrating the following three components. The robot recognizes the flutist’s gestures by using a robust Hough line detection with random sample consensus and finite state machines. The drummer’s playing speed is recognized using spectro-temporal patternmatching based real-time beat-tracking. The robot plays the theremin using the feedforward control method based on the theremin’s pitch and volume models. We preliminarily evaluate the performance using the difference of onset timings between the played sounds and the reference onset timings calculated from a score. The results suggest that our system realizes a trio-ensemble with two humans and a robot.
Can mandibular advancement devices be a satisfactory substitute for short term use in patients on nasal continuous positive airway pressure?

BACKGROUND Mandibular advancement devices (MADs) can successfully control both snoring and obstructive sleep apnoea (OSA). Many patients on nasal continuous positive airway pressure (NCPAP) for OSA would like a more portable alternative, even if only temporarily. This study assesses what proportion of patients with OSA already on NCPAP can successfully use a MAD for short periods (up to 1 month) as a temporary alternative to NCPAP. METHODS Fifty patients with OSA, already on NCPAP for at least 3 months, were recruited by invitation. They were provided with a simple fixed MAD estimated to provide 75% of maximum mandibular protrusion. Sleep studies using a portable home recorder were performed on and after three nights without NCPAP to provide control data. Following acclimatisation to the MAD, sleep studies were also planned after 3, 7, and 28 days while using the MAD. If their overnight >4% SaO(2) dips per hour deteriorated to >20 or the Epworth sleepiness score (ESS) rose to >9 (or increased by >4 over baseline) on nights 3 or 7, they were then deemed to have failed the trial and were withdrawn. RESULTS Of the 50 patients entered, one had inadequate teeth for a MAD and 31 gave up trying to use the device during the acclimatisation period because of side effects. Of the 18 prepared to use the device, two patients failed at night 3, five at night 7, and two at night 28. Thus, nine patients remained controlled by our criteria at night 28. On average, sleep study indices while using the MAD were poor compared with the night on NCPAP. CONCLUSIONS Simple MADs are poorly tolerated by patients with OSA already on NCPAP. OSA was adequately controlled by our criteria in 32% of those recruited for the equivalent of a weekend, in 22% for 1 week, and in 18% for up to 1 month. Better tolerated devices would be likely to improve on these figures.
The Physcomitrella patens exocyst subunit EXO70.3d has distinct roles in growth and development, and is essential for completion of the moss life cycle.

The exocyst, an evolutionarily conserved secretory vesicle-tethering complex, spatially controls exocytosis and membrane turnover in fungi, metazoans and plants. The exocyst subunit EXO70 exists in multiple paralogs in land plants, forming three conserved clades with assumed distinct roles. Here we report functional analysis of the first moss exocyst subunit to be studied, Physcomitrella patens PpEXO70.3d (Pp1s97_91V6), from the, as yet, poorly characterized EXO70.3 clade. Following phylogenetic analysis to confirm the presence of three ancestral land plant EXO70 clades outside angiosperms, we prepared and phenotypically characterized loss-of-function Ppexo70.3d mutants and localized PpEXO70.3d in vivo using green fluorescent protein-tagged protein expression. Disruption of PpEXO70.3d caused pleiotropic cell elongation and differentiation defects in protonemata, altered response towards exogenous auxin, increased endogenous IAA concentrations, along with defects in bud and gametophore development. During mid-archegonia development, an abnormal egg cell is formed and subsequently collapses, resulting in mutant sterility. Mutants exhibited altered cell wall and cuticle deposition, as well as compromised cytokinesis, consistent with the protein localization to the cell plate. Despite some functional redundancy allowing survival of moss lacking PpEXO70.3d, this subunit has an essential role in the moss life cycle, indicating sub-functionalization within the moss EXO70 family.
