On Comparison Between Repetitive Controller and PI Controller Tracking Performance
Authors: Kurniawan Edi 
Published: November 2016

Tracking periodic signals are common task in many control problems. One of the examples is movement control of pick and place robot in industry. The requirement of high tracking accuracy becomes very important in many applications. Therefore, a sophisticated control algorithm that manages to achieve high accuracy tracking of periodic command is required. Repetitive Control (RC) based on internal model principle is one of control schemes that can be employed to achieve perfect tracking of periodic signal. On the other hand, Proportional Integral (PI) controller can also be used for tracking. This paper compares the tracking performance of PI controller, RC, and PI with RC, where PI with RC here is integration between PI controller and RC. Step by step design to obtain the parameters of PI, RC and PI with RC are given. A simulation on servo motor system is carried out to assess the performance of RC, PI, andPI with RC respectively. From the simulation results, the transient response and tracking accuracy are thoroughly discussed.

Published: December 2016

Abstract
Channel assignment in 2.4 GHz band of 802.11 standard is still important issue as a lot of 2.4 GHz devices are in use. This band offers only three non-overlapping channels, so in crowded environment users can suffer from high interference level. In this paper, a greedy algorithm inspired by the Prim’s algorithm for finding minimum spanning trees (MSTs) in undirected graphs is considered for channel assignment in this type of networks. The proposed solution tested for example network distributions achieves results close to the exhaustive approach and is, in many cases, several orders of magnitude faster.

Published: November 2016

Abstract
This paper proposes a nonlinear average model of three levels NPC inverter. This model takes into account the semiconductor non-linearity and static characteristics of these devices. The proposed technique uses experimental results to evaluate the different devices parameters. The developed nonlinear average model allows dissipated power and junction temperature evaluation. Unlike the circuit model (fine model), the proposed method has less computational burden. It can be applied to three levels Neutral-Point-Clamped inverter (NPC).

Zusammenfassung
Der Beitrag beschäftigt sich mit der Bedeutung und Bewertung von touristischen Sport-Events zur Beurteilung ihrer Förderwürdigkeit durch die öffentliche Hand. Anhand bestehender Instrumente der Event-Wirkungsforschung und der strategischen Bewertung von Events wurden Kriterien abgeleitet, die Verantwortlichen aus dem Tourismus helfen können, die Förderwürdigkeit von Events zu überprüfen. Anhand von ex-post Wertschöpfungsanalysen sowie einer Dokumentenanalyse wurde die Anwendung der Kriterien überprüft. Die Analyse zeigt, dass insbesondere bei Sport-Events mit einem hohen Budget die Relation zwischen Investitionen und regionaler Wertschöpfung weniger groß als bei kleineren Events mit einem geringeren Budget ausfällt. Zur Überprüfung der Förderwürdigkeit eines Events sollte die strategische Übereinstimmung des Events mit der betreffenden Region geprüft werden. Dafür eignen sich insbesondere die Analyse des Kernangebots sowie die Überprüfung der Zielgruppen und der Zielmärkte. Durch den Einbezug wichtiger Anspruchsgruppen ist es möglich, negative Auswirkungen von Events zu minimieren, zu kompensieren oder einen langfristigen Nutzen von Investitionen sicherzustellen. Dadurch wird auch die Akzeptanz von Events bei der Bevölkerung positiv beeinflusst.
Semantic Congruence Accelerates the Onset of the Neural Signals of Successful Memory Encoding

Published: December 2016

As the stream of experience unfolds, our memory system rapidly transforms current inputs into long-lasting meaningful memories. A putative neural mechanism that strongly influences how input elements are transformed into meaningful memory codes relies on the ability to integrate them with existing structures of knowledge or schemas. However, it is not yet clear whether schema-related integration neural mechanisms occur during online encoding. In the current investigation, we examined the encoding-dependent nature of this phenomenon in humans. We showed that actively integrating words with congruent semantic information provided by a category cue enhances memory for words and increases false recall. The memory effect of such active integration with congruent information was robust, even with an interference task occurring right after each encoding word list. In addition, via electroencephalography, we show in 2 separate studies that the onset of the neural signals of successful encoding appeared early (∼400 ms) during the encoding of congruent words. That the neural signals of successful encoding of congruent and incongruent information followed similarly ∼200 ms later suggests that this earlier neural response contributed to memory formation. We propose that the encoding of events that are congruent with readily available contextual semantics can trigger an accelerated onset of the neural mechanisms, supporting the integration of semantic information with the event input. This faster onset would result in a long-lasting and meaningful memory trace for the event but, at the same time, make it difficult to distinguish it from plausible but never encoded events (i.e., related false memories).SIGNIFICANCE STATEMENTConceptual or schema congruence has a strong influence on long-term memory. However, the question of whether schema-related integration neural mechanisms occur during online encoding has yet to be clarified. We investigated the neural mechanisms reflecting how the active integration of words with congruent semantic categories enhances memory for words and increases false recall of semantically related words. We analyzed event-related potentials during encoding and showed that the onset of the neural signals of successful encoding appeared early (∼400 ms) during the encoding of congruent words. Our findings indicate that congruent events can trigger an accelerated onset of neural encoding mechanisms supporting the integration of semantic information with the event input.

Published: November 2016

Background & Aims: Acute-on-chronic liver failure (ACLF) is characterized by a rapid progression to multiple organ failure and is associated with a very high mortality rate of 50-90%. Novel therapies are being investigated such as Erythropoietin (EPO). The aim of this prospective cohort study was to analyse the value of EPO in predicting prognosis and determine which patients may benefit most from EPO therapy.
Methods: According to the EASL-CLIF criteria, 104 consecutive patients were diagnosed with ACLF, and separated into two groups based on the type of insult: bleeding (Group A=31) or non-bleeding (Group B=73). In addition to a complete biochemical work-up and calculation of relevant prognostic scores, levels of EPO were measured on admission and correlated to the type of insult and final outcome.
Results: Fifteen patients from Group A (mean age 60.32±9.29 years) had a lethal outcome and higher values of EPO on admission (319.26±326.58 mIU/ml) (p<0.005), compared to the 37 patients from Group B (mean age 59.9±10.19 years) with EPO levels at admission of 29.88±34.6 mIU/mL. In Group B, a cut-off EPO value of 30.65 mIU/mL had a sensitivity of 87.5% and a specificity 57.4% in predicting lethal outcome with an AUROC of 0.823. In Group A, a cut-off value of 229.95 mlU/mL had a sensitivity and specificity of 53.3% and 92.7%, respectively. The AUROC for this cut-off was 0.847.
Conclusions: Erythropoietin is superior to the standard prognostic scores in predicting 28-day mortality. Lower levels of EPO were detected in patients without bleeding as an insult indicating a possible therapeutic benefit in these patients.

Background & Aims: Contrast-enhanced ultrasound (CEUS) and contrast-enhanced computed tomography (CECT) are used to assess the response of hepatocellular carcinoma after transarterial chemoembolization. Our aim was to perform a systematic review to compare CEUS and CECT for therapeutic response assessment to transarterial chemoembolization in the treatment of hepatocellular carcinoma.
Method: PubMed, Embase, and the Cochrane Library databases were searched from inception until January 1, 2016. Participants: patients with hepatocellular carcinoma. Intervention: transarterial chemoembolization and CECT vs CEUS.
Results. Sixteen studies were included in the systematic review. The total number of patients was 858 and the mean patient age ranged from 42 to 73 years. The mean tumor size ranged from 1.0 cm to 4.3 cm. The sensitivity and specificity of CEUS ranged from 46% to 100% and 65% to 100%, respectively, and that of CECT ranged from 34% to 87% and 92% to 100%, respectively. The accuracy of CEUS ranged from 72.6% to 100% and that of CECT from 61% to 94%. Marked heterogeneity was present among the studies.
Conclusion: CEUS is comparable with CECT for the therapeutic response assessment after transarterial chemoembolization.

A Case of Acute Liver Failure during Ritonavir-Boosted Paritaprevir, Ombitasvir and Dasabuvir Therapy in a Patient with HCV Genotype 1b Cirrhosis
Authors: Masetti Marco , Magalotti Donatella , Martino Elena , Andreone Pietro , Scuteri Alessandra , Zoli Marco 
Published: November 2016

Background: Ritonavir-boosted Paritaprevir, Ombitasvir and Dasabuvir plus Ribavirin is one of the current recommended therapies for HCV genotype 1b monoinfected patients in compensated (Child-Pugh A) cirrhosis. Whether it is known that the worsening of liver function is a rare but possible complication of Ritonavir-boosted Paritaprevir, Ombitasvir and Dasabuvir therapy, to our knowledge no description of treatment-related acute liver failure is available in the literature.
Case presentation: An 84-year-old Caucasian man with chronic compensated HCV genotype 1b cirrhosis received Ritonavir-boosted Paritaprevir, Ombitasvir and Dasabuvir plus Ribavirin therapy. After 13 days he developed grade 4 hyperbilirubinaemia and ascites. Even though treatment was promptly stopped, patient’s clinical condition worsened, and he underwent hospitalization, several paracentheses, and developed sub-acute kidney injury. The bilirubinemia returned under three times the upper normal limit only after five months. Notably, he achieved sustained virological response despite the very short duration of therapy.
Conclusion: Hepatic decompensation and acute liver failure are rare but severe complications of Ritonavir-boosted Paritaprevir, Ombitasvir and Dasabuvir plus Ribavirin therapy in patients with compensated cirrhosis. Close monitoring for signs or symptoms of worsening of liver disease is mandatory, and further research for stratifying risk factors are required.

Primary Biliary Cirrhosis and Primary Sclerosing Cholangitis: an Update on MR Imaging Findings with Recent Developments
Authors: Kovač Jelena Djokić , Weber Marc-André 
Published: November 2016

Primary sclerosing cholangitis (PSC) and primary biliary cirrhosis (PBC) are the most common immune-mediated chronic cholestatic liver diseases leading to cirrhosis and liver failure. Although magnetic resonance imaging (MRI) is not a necessary procedure for the diagnosis of PBC, MRI is recommended for monitoring disease progression and early detection of complications. Even though liver cirrhosis subtypes have similar MR imaging features, there are some findings which could indicate PBC, such as the periportal halo sign. Additionally, MRI using diffusion-weighted imaging with apparent diffusion coefficient measurements provides non-invasive assessment of the stage of liver fibrosis. The role of cholangiography is crucial for the diagnosis of PSC. Since endoscopic retrograde cholangiography is an invasive procedure with occasional post-procedural complications, the latest guidelines suggest magnetic resonance cholangiography as a reference procedure for evaluation of patients suspected with PSC. Characteristic magnetic resonance cholangiography findings include multiple segmental strictures with slightly dilated ducts among them, usually on both intrahepatic and extrahepatic bile ducts. Furthermore, magnetic resonance cholangiography is useful in the follow-up of these patients, allowing for timely diagnosis of complications such as cholangiocellular carcinoma. With the exception of ursodeoxycholic acid, which slows the progression of PBC, the only curative treatment for both PSC and PBC is still liver transplantation. However, recurrent disease occurs in some patients indicating the need for development of new more effective therapies.

OBJECTIVES:This study was designed to determine whether black adolescents from disadvantaged backgrounds who have an unrelenting determination to succeed would, as adults, show “skin-deep resilience” by faring well in psychosocial domains but also show a heightened chance of having a chronic disease, specifically type 2 diabetes.METHODS:Secondary data analyses were executed with the use of waves 1 and 4 of the US Longitudinal Study of Adolescent to Adult Health (Add Health). At wave 1, when participants were age 16, data were obtained on a behavioral style termed “striving.” Striving includes high aspirations, unwavering persistence, investment in education, and avoidance of activities that sidetrack success. At wave 4, when participants were age 29, college graduation, personal income, symptoms of depression, and type 2 diabetes status were assessed.RESULTS:Black and non-Hispanic white youth who displayed striving during adolescence evinced, at age 29, a higher likelihood of college graduation, greater personal income, and fewer symptoms of depression than did nonstrivers. Among black participants, the findings were consistent with the “skin-deep resilience” pattern for type 2 diabetes. High-striving black adolescents in the most disadvantaged families had a greater likelihood of developing type 2 diabetes during adulthood than did similar high-striving black adolescents living in more privileged families. The skin-deep resilience pattern did not emerge among non-Hispanic white participants.CONCLUSIONS:This study is the first to show that an unrelenting determination to succeed among black adolescents from disadvantaged backgrounds forecasts an elevated risk of developing type 2 diabetes during adulthood.
