Subcuticular catgut versus polyglactin 910 in scar formation in sheep

The aim of this double blind prospective experimental study was to compare the influence of polyglactin 910 (Vicryl, Ethycon ) and plain catgut (So�cat-Plein, Braun) as subcuticular tissue sutures on wound healing and scar formation in sheep. Scar excision together with the surrounding tissue was made three months later. Scars were compared visually, photographed and examined under a light microscope. All scars were cosmetically acceptable, linearly hardly visible, aplanated and less than 1 mm in width with no difference between the parts in which plain catgut or polyglactin 910 were used. All photographs were examined by a plastic surgeon as well as by a dermatologist and they confirmed that all scars were cosmetically acceptable, hardly visible, aplanated and less than 1 mm in width. During the light microscopic examination done by the dermatologist foreign body granulomas were found in two scars where the subcuticular plain catgut was used. Concerning the plain catgut as an animal and foreign body granuloma inductor, the use of polyglactin 910 seems to be be�er.
Novel Stable Walking for Humanoid Robot Using Particle Swarm Optimization Algorithm

This paper describes a novel walking gait generation algorithm based on inverse kinematics for a biped robot. The proposed algorithm uses the PSO (Particle Swarm Optimization) algorithm in order to find optimized values for the five walking algorithm parameters. The proposed experiment approach is tested on a small-sized humanoid robot in the DCSELAB, VNUHCM. Simulation and experimental results reveal that using the PSO algorithm with an efficient fitness function can significantly reduce learning time. Moreover, a considerable fast walking speed is achieved. Keywords-PSO; walking robot; learning time; walking speed
Randomized View Reconciliation in Permissionless Distributed Systems

In a sybil attack, an adversary creates a large number of fake identities/nodes and have them join the system. Computational puzzles have long been investigated as a possible sybil defense: If a node fails to solve the puzzle in a timely fashion, it will no longer be accepted by other nodes. However, it is still possible for a malicious node to behave in such a way that it is accepted by some honest nodes but not other honest nodes. This results in different honest nodes having different views on which set of nodes should form the system. Such view divergence, unfortunately, breaks the overarching assumption required by many existing security protocols. Partly spurred by the growing popularity of Bitcoin, researchers have recently formalized the above view divergence problem and proposed interesting solutions (which we call view reconciliation protocols). For example, in CRYPTO 2015, Andrychowicz and Dziembowski proposed a view reconciliation protocol with $\Theta(N)$ time complexity, with $N$ being the number of honest nodes in the system. All existing view reconciliation protocols so far have a similar $\Theta(N)$ time complexity. As this paper's main contribution, we propose a novel view reconciliation protocol with a time complexity of only $\Theta(\frac{\ln N}{\ln\ln N})$. To achieve such an exponential improvement, we aggressively exploit randomization.
th Information Systems International Conference 2017 , ISICO 2017 , 6-8 November 2017 , Bali , Indonesia Analysis on Factors Influencing Textile Cyberpreneur ’ s Intention to Adopt Cloud-Based m-Retail Application

In this era of smartphone utilization, business owners such as textile cyberpreneurs may conduct mobile retail (mretail) via cloud-based m-retail application. As cloud and e-commerce services are still lowly adopted by Malaysian business owners, further investigation must be done in examining their adoption intention. Normally for businessmen, the technology utilization may associate with tasks which are required to be performed. Moreover, their own behaviour may influence the usage intention. Hence, this study intends to investigate the influences of task-technology fit (TTF) model and theory of planned behaviour (TPB) towards textile cyberpreneur’s intention to adopt cloud-based m-retail application. 348 respondents have participated in this study and analysis of findings have shown that task-technology fit, attitude, subjective norm and perceived behavioural control have significant positive effects on textile cyberpreneur’s behavioural intention. Task-technology fit construct has also been found as the most influential factor towards adoption intention. The practical implications and future recommendations are presented in this study for additional knowledge. © 2018 The Authors. Published by Elsevier B.V.

Coronary artery bypass graft (CABG) and the diabetic patient: current perspectives

: Diabetes increases both the severity and the risks of coronary artery disease. For such patients, revascularization by coronary artery bypass grafting (CABG) has consistently improved survival and event free survival in multiple studies compared to percutaneous revascularization (PCI). Evolving treatments, the growing volume of patients with diabetes who have coronary disease, and the cost of their care mandates regular reevaluation of the evidence on which treat-ment by CABG or PCI is based. This review provides current perspectives on the role of CABG based on analysis of information from newly reported major trials such as Taxus drug eluting stent versus coronary artery bypass surgery (SYNTAX) and Future revascularization evaluation in patients with diabetes mellitus:optimal management of multiple vessel disease (FREEDOM). Also evaluated are technical advances in CABG and improvements in the care of CABG patients with diabetes which should be incorporated in “best practice” surgical revascularization. The accumulated evidence shows clear superiority of CABG for patients with diabetes and multivessel disease, and in particular the benefits of CABG employing multiple arterial conduits.
Sexual Variation in Fisheries Research and Management: When Does Sex Matter?

In fish, sex determination is a plastic process regulated by a relatively small number of genes that, in turn, leads to a cascade of organism level effects. In other animal taxa, intersexual variation is widespread and has implications in the realms of morphology, behavior, physiology, and bioenergetics. Although relatively well documented in the literature focusing on mammals, birds, and reptiles, the degree to which sex-specific variation is considered is unknown in fish and fisheries research. We examined the scientific literature to evaluate the important sex-related differences in fish and highlighted why some of these differences are of great biological consequence. Sex-specific differences in morphology included sexual size dimorphism, external traits such as coloration, and internal anatomy such as neuron structure. Behavioral differences between the sexes are often linked to reproduction, but there are some documented differences (i.e., variation in aggression and predator avoidance) that are independent of the reproductive period. The potential for sex-related physiological differences are relatively unexplored for fish, although there is strong evidence for disparity in hormone regulation, stress, and immune responses between the sexes. Sex-related variation is also poorly examined in the field of bioenergetics despite the fact that differences in energy requirements and expenditure should and do vary between the sexes. A quantitative literature review of several prominent fisheries journals revealed that sex is often overlooked in fish and fisheries research (between 15 and 44% of articles), which may impair the ability of researchers to detect biologically relevant differences, which in turn can greatly affect management decisions. Although there has been a growing recognition that intra-specific variation (at the population level) is important in fisheries management and research, there is also a need to consider that intersexual diversity exists and is important to understand, conserve, and manage fish and fisheries resources.
Photodissociation Dynamics

Photodissociation is the breaking of one or several bonds in a molecule through the absorption of light. Depending on the number of photons required to fragment the molecule, one distinguishes between singleand multiphoton dissociation. In the case of dissociation with a single photon, usually in the optical or the ultraviolet region, the molecule is promoted from the ground electronic state Q X to an excited electronic state, for example Q A, as schematically illustrated in Figure 1. In multiphoton dissociation, several or many photons, mostly in the infrared region, excite the molecule until the energy exceeds the dissociation energy of the weakest bond and thus enables the molecule to break apart (see Multiphoton Excitation). In the present article we will exclusively focus on dissociation with single photons. An example is the photodissociation of isocyanic acid (equation 1) with two spin-allowed and one spin-forbidden, chemically different product channels,
Chapter 2 Surgical Approaches for Total Knee Arthroplasty

Total knee arthroplasty surgery is a current practice in orthopedic surgery. The success of this intervention consists in part in the realignment of the lower extremity’s anatomical axis, adequate implant orientation and design, good implant fixation, proper soft tissue balancing, and stability. A good exposure also allows optimal placement of the components. Our preferred approach is the median parapatellar approach in most cases. However, the orthopedic surgeon may face anatomical variants associated with knee types that may complicate the classic approach. We are reviewing multiple surgical approaches also used by us in our clinic in total knee arthroplasty, as well as additional techniques in these surgical approaches. The MIS approach can be used in many cases to reduce pain and speed the healing process. All of the total knee arthroplasty approaches are detailed with anatomical illustrations along with advantages and disadvantages of each. The ultimate goal is to restore knee function as quickly as possible and to preserve the anatomical integrity of the joint.
Successful Bilateral Total Knee Replacements with ongoing Allergic Contact Dermatitis to Benzoyl Peroxide

Contact allergy to metals in total knee arthroplasties is a well-documented event due to its occurrence in the general population; however, sensitivity to other components, such as the chemicals used in the bone cement, is becoming more prominent as joint replacement surgeries continue to rise. We report a case of benzoyl peroxide (BPO) allergy leading to a persistent skin reaction in a patient with normal mechanical function after bilateral total knee arthroplasty. A thorough review of the literature reveals all published cases of orthopedic implant patients with dermatological reactions and sensitivity to benzoyl peroxide concomitantly showed symptoms of joint failure, including pain, swelling, and prosthetic loosening. Our case study presents a patient who has developed a delayed-type sensitivity reaction without joint dysfunction of any kind. This clinical presentation is a variant of those previously reported and represents a new genre of treatment challenges for surgeons and dermatologists. In this article, we discuss the implications this case has in preventing post-surgical complications and possible treatment options for this novel patient presentation.
Effects of river temperature and climate warming on stock‐specific survival of adult migrating Fraser River sockeye salmon (Oncorhynchus nerka)

Mean summer water temperatures in the Fraser River (British Columbia, Canada) have increased by ∼1.5 °C since the 1950s. In recent years, record high river temperatures during spawning migrations of Fraser River sockeye salmon (Oncorhynchus nerka) have been associated with high mortality events, raising concerns about long‐term viability of the numerous natal stocks faced with climate warming. In this study, the effect of freshwater thermal experience on spawning migration survival was estimated by fitting capture–recapture models to telemetry data collected for 1474 adults (captured in either the ocean or river between 2002 and 2007) from four Fraser River sockeye salmon stock‐aggregates (Chilko, Quesnel, Stellako‐Late Stuart and Adams). Survival of Adams sockeye salmon was the most impacted by warm temperatures encountered in the lower river, followed by that of Stellako‐Late Stuart and Quesnel. In contrast, survival of Chilko fish was insensitive to the encountered river temperature. In all stocks, in‐river survival of ocean‐captured sockeye salmon was higher than that of river‐captured fish and, generally, the difference was more pronounced under warm temperatures. The survival–temperature relationships for ocean‐captured fish were used to predict historic (1961–1990) and future (2010–2099) survival under simulated lower river thermal experiences for the Quesnel, Stellako‐Late Stuart and Adams stocks. A decrease of 9–16% in survival of all these stocks was predicted by the end of the century if the Fraser River continues to warm as expected. However, the decrease in future survival of Adams sockeye salmon would occur only if fish continue to enter the river abnormally early, towards warmer periods of the summer, as they have done since 1995. The survival estimates and predictions presented here are likely optimistic and emphasize the need to consider stock‐specific responses to temperature and climate warming into fisheries management and conservation strategies.
Modeling Creativity: Tracking Long-term Lexical Change

The concept of creativity underwent a period of shifting meaning and rapid adoption in the twentieth century. Following from a narrow early scope of usage, in which it carried largely religious connotations, the word ‘creative’ grew broader and adopted the more subjective meanings we are familiar with today. Though many contemporary observers point out the vagueness of the term, creativity’s power comes from a particular mix of meanings and connotations accrued over time. Still, there is no clear inventory of the higher-level concepts around discussion of creativity and how they evolved. Additionally, because of the rapid increase in usage, early uses of 'creativity' may be overlooked as they are overshadowed by much more common later uses. In this paper, we present a method for tracking the different styles of discourse around a concept over time, developed for following the evolution of 'creativity' but applicable to other domains. Our approach is an application of Latent Dirichlet Allocation (LDA) trained topic models, with three novel steps in their preparation:
Physically based shading in theory and practice

The Disney BRDF, presented in this course in 2012, continues to be applied to virtually all surfaces in every production at Walt Disney Animation Studios. This year we will present updates we have made to this model, the most signiﬁcant of which is the integration of subsurface scattering. Energy conservation is becoming increasingly important—especially within a path-traced rendering context—so having an integrated model is essential. The integrated model also improves ease of use and consistency of results.
Comparison of Chronologic Change in the Size and Contrast-Enhancement of Ablation Zones on CT Images after Irreversible Electroporation and Radiofrequency Ablation

Objective To compare short-, mid-, and long-term follow-up ablation zone volume alterations as well as imaging features on contrast-enhanced computed tomography (CT) after irreversible electroporation (IRE) of primary and secondary liver tumors with findings subsequent to radiofrequency ablation (RFA). Materials and Methods Volume assessment of 39 ablation zones (19 RFA, 20 IRE) after intervention was performed at four time intervals (day 0 [t1; n = 39], day 1–7 [t2; n = 25], day 8–55 [t3; n = 28], after day 55 [t4; n = 23]) on dual-phase CT. Analysis of peripheral rim enhancement was conducted. Lesion's volume decrease relative to the volume at t1 was calculated and statistically analyzed with respect to patient's sex, age, ablation modality (IRE/RFA), and history of platinum-based chemotherapy (PCT). Results No influence of patient's sex or age on ablation volume was detected. The decrease in ablation zones' volume was significantly larger (p < 0.05 for all time intervals) after IRE (arterial phase, 7.5%; venous phase, 9.7% of initial volume) compared to RFA (arterial phase, 39.6%; venous phase, 45.3% of initial volume). After RFA, significantly smaller decreases in the ablation volumes, in general, were detected in patients treated with PCT in their history (p = 0.004), which was not detected after IRE (p = 0.288). In the arterial phase, peripheral rim enhancement was frequently detected after both IRE and RFA. In the venous phase, rim-enhancement was depicted significantly more often following IRE at t1 and t2 (pt1 = 0.003, pt2 < 0.001). Conclusion As per our analysis, ablation zone volume decreased significantly in a more rapid and more profound manner after IRE. Lesion's remodeling after RFA but not IRE seems to be influenced by PCT, possibly due to the type of cell death induced by the different ablation modalities.
Modeling the growth of organisms validates a general relation between metabolic costs and natural selection

Metabolism and evolution are closely connected: if a mutation incurs extra energetic costs for an organism, there is a baseline selective disadvantage that may or may not be compensated for by other adaptive effects. A long-standing, but to date unproven, hypothesis is that this disadvantage is equal to the fractional cost relative to the total resting metabolic expenditure. This hypothesis has found a recent resurgence as a powerful tool for quantitatively understanding the strength of selection among different classes of organisms. Our work explores the validity of the hypothesis from first principles through a generalized metabolic growth model, versions of which have been successful in describing organismal growth from single cells to higher animals. We build a mathematical framework to calculate how perturbations in maintenance and synthesis costs translate into contributions to the selection coefficient, a measure of relative fitness. This allows us to show that the hypothesis is an approximation to the actual baseline selection coefficient. Moreover we can directly derive the correct prefactor in its functional form, as well as analytical bounds on the accuracy of the hypothesis for any given realization of the model. We illustrate our general framework using a special case of the growth model, which we show provides a quantitative description of overall metabolic synthesis and maintenance expenditures in data collected from a wide array of unicellular organisms (both prokaryotes and eukaryotes). In all these cases we demonstrate that the hypothesis is an excellent approximation, allowing estimates of baseline selection coefficients to within 15% of their actual values. Even in a broader biological parameter range, covering growth data from multicellular organisms, the hypothesis continues to work well, always within an order of magnitude of the correct result. Our work thus justifies its use as a versatile tool, setting the stage for its wider deployment.
Risk Assessments : A Precarious Approach for Criminal Justice Reform

As risk assessments become increasingly recommended and adopted as a tool for criminal justice reform, the technical community and advocates alike must ask the right questions. Thus far, most analyses of risk assessments presume that narrow computational definitions of fairness are sufficient to ensure that the impacts of risk assessments are themselves fair and take for granted that risk assessments are an effective tool for advancing criminal justice reform. This paper interrogates both assumptions to highlight how even “fair” risk assessments can be unfair and hinder efforts to reform the criminal justice system. This analysis suggests several ways in which the field of fair machine learning must expand the considerations and questions that it deems relevant to evaluating and deploying risk assessments.
Ultralight or Heavyweight? The Interactive Effects of Gear Strength and Air Exposure on Reflex Impairment in Largemouth Bass

AbstractAlthough much is known about the factors that influence the effects of catch-and-release angling on fish condition and survival, relatively little is known about the effects of fishing gear strength on fight time and, hence, fish condition. Moreover, little is known about how gear strength and fight time interact with air exposure duration to ultimately influence the level of exhaustion experienced by fish at time of release. Here we systematically varied fishing gear strength (ultralight versus medium-heavy) and air exposure duration (0 versus 120 s) when targeting Largemouth Bass Micropterus salmoides. We relied on reflex impairment (using five different reflexes) as a real-time indicator of fish condition. Largemouth Bass fight durations were highly variable between fishing gear types and across fish sizes. Largemouth Bass captured on ultralight fishing gear experienced longer fight times, and there was a stronger positive relationship between fish length and fight time than for those captured .
Inhibition of Salmonella enterica serovar Dusseldorf by enterocin A in gnotobiotic Japanese quails

The protective (ENT1) and therapeutic (ENT2) effects of enterocin A (Ent), produced by Enterococcus faecium EK13, against Salmonella enterica serovar Dusseldorf SA31 was determined in a model of gnotobiotic Japanese quails. Twenty-one 3 days old birds were divided into 3 groups of equal size; (ENT1, ENT2 and control group – CG). They were experimentally infected with SA31 (107 cfu/ml) per os. For the group ENT1, Ent A (200 μl of 25 600 AU/ml) was administered 8 h before infection with SA31 strain and for the group ENT2, treatment with Ent A was administered 8 h a�er infection; CG was infected with SA31 and not treated with Ent A. Sampling of the feces was performed 8, 24, 48 and 168 h a�er infection. At the end of the experiment also the content of the caecum and ileum was analyzed. A log 1.37 reduction of SA31 colonization in feces of the group ENT1 was found a�er 8 h in comparison with CG. A�er 24 h, a significant difference in SA31 colonization was observed when comparing CG and ENT2. A�er 48 h, a lower colonization of SA31 was found in both groups which continued until the end of the experiment (168 h). At the same time, reduction of Salmonella enterica serovar Dusseldorf was detected in the content of the caecum (2.44 log) and ileum (3.16 log) in ENT2 but not in ENT 1 when compared with control group. These observations indicate stronger therapeutic effect of Ent A than prophylactic one in the digestive tract of gnotobiotic Japanese quails.
