Purpose

This multinational study evaluated the antitumor activity of nivolumab in nasopharyngeal carcinoma (NPC). Tumor and plasma-based biomarkers were investigated in an exploratory analysis.

Patients and Methods

Patients with multiply pretreated recurrent or metastatic NPC were treated with nivolumab until disease progression. The primary end point was objective response rate (ORR) and secondary end points included survival and toxicity. The expression of programmed death-ligand 1 (PD-L1) and human leukocyte antigens A and B in archived tumors and plasma clearance of Epstein-Barr virus DNA were correlated with ORR and survival.

Results

A total of 44 patients were evaluated and the overall ORR was 20.5% (complete response, n = 1; partial response, n = 8). Nine patients received nivolumab for > 12 months (20%). The 1-year overall survival rate was 59% (95% CI, 44.3% to 78.5%) and 1-year progression-free survival (PFS) rate was 19.3% (95% CI, 10.1% to 37.2%). There was no statistical correlation between ORR and the biomarkers; however, a descriptive analysis showed that the proportion of patients who responded was higher among those with PD-L1 positive tumors (> 1% expression) than those with PD-L1-negative tumors. The loss of expression of one or both human leukocyte antigen class 1 proteins was associated with better PFS than when both proteins were expressed (1-year PFS, 30.9% v 5.6%; log-rank P = .01). There was no association between survival and PD-L1 expression or plasma Epstein-Barr virus DNA clearance. There was no unexpected toxicity to nivolumab.

Conclusion

Nivolumab has promising activity in NPC and the 1-year overall survival rate compares favorably with historic data in similar populations. Additional evaluation in a randomized setting is warranted. The biomarker results were hypothesis generating and validation in larger cohorts is needed.

Introduction

This study investigated the safety and effectiveness of a new integrated aerobic and resistance exercise training prescription (SPRINT) using two different sets of exercise equipment: a suite of large International Space Station–like exercise equipment similar to what is found on the International Space Station and a single device with aerobic and resistance exercise capability in the spaceflight analog of bed rest (BR).

Methods

Subjects (n = 34) completed 70 d of 6° head down tilt BR: 9 were randomized to remain sedentary (CONT), 9 to exercise training using traditional equipment (EX), 8 to exercise using traditional equipment and low-dose testosterone supplementation (ExT), and 8 to exercise using a combined resistance and aerobic flywheel device. Peak aerobic capacity, ventilatory threshold, cardiac morphology and function (echocardiography), muscle mass (magnetic resonance imaging) and strength/power (isokinetic, leg press, and vertical jump), and bone health (bone mineral density, blood and urine bone markers) were assessed before and after BR.

Results

The SPRINT protocol mitigated BR-induced muscle and cardiac deconditioning regardless of the exercise device used. Molecular markers of bone did not change in the CONT or EX groups. Peak aerobic capacity was maintained from pre- to post-BR in all exercise groups similarly, whereas significant declines were observed in the CONT group (~10%). Significant interaction effects between the CONT group and all EX groups were observed for muscle performance including leg press total work, isokinetic upper and lower leg strength, vertical jump power, and maximal jump height as well as muscle size.

Conclusions

This is the first trial to evaluate multisystem deconditioning and the role of an integrated exercise countermeasure. These findings have important implications for the design and implementation of exercise-based countermeasures on future long-duration spaceflight missions.
Cyclical Job Ladders by Firm Size and Firm Wage
Authors: Haltiwanger John C. , Hyatt Henry R. , Kahn Lisa B. , McEntarfer Erika
Published: March 2018

We study whether workers progress up firm wage and size job ladders, and the cyclicality of this movement. Search theory predicts that workers should flow toward larger, higher paying firms. However, we see little evidence of a firm size ladder, partly because small, young firms poach workers from all other businesses. In contrast, we find strong evidence of a firm wage ladder that is highly procyclical. During the Great Recession, this firm wage ladder collapsed, with net worker reallocation to higher wage firms falling to zero. The earnings consequences from this lack of upward progression are sizable. (JEL D22, E24, E32, J31, J63, J64, L25)

Since the 1980s the concepts of spatial forms commemorating Holocaust, or to embrace it wider, the victims of the Nazi regime, have been increasingly moving away from the principle presented in the period of “memory witnesses and guardians”. For a good reason here Robert Musil’s opinion is commonly quoted; claiming the monuments which had been erected to draw a great attention, remain invisible. James E. Young – the author of the term counter‑monument referring to objects representing a new way of thinking of their messages, their roles and forms they are able to express – wrote at the beginning of the 1990s: “The further shifted in the past are the events of WWII, the more glamorous its monuments become”. Whereas several most significant commemorating monuments of a new trend gain their minimalist, nearly non‑existing form, a great majority of them are of incomparably larger scale with a wider range of means of expression. The examples selected to be analysed are contemporary Polish projects of commemorating forms in Bełżec (proj. A. Sołyga, Z. Pidyk, M. Roszczyk, DDJM), in Gross‑Rosen (proj. Nizio Design International), in Michniów (proj. Nizio Design International) and in Sobibór (proj. M. Urbanek, P. Michalewicz, Ł. Mieszkowski). In linear narrative there is an active presence of the visitors provoked; the scenery is meant to evoke threat, confusion and seclusion. Commemorating forms designed with a flourish are becoming total monuments, accused of aestheticization of death. Monuments as culture memory bearers in the meaning suggested by Aleida Assmann, have always been expressions of their founders’ intentions and their attitudes towards the past, and like in all other times, they constitute a reflection of us– the contemporary.
"Czy to jest zamiast, w zastępstwie zagłady?"

Tony Judt (1948‑2010) descended from a Jewish family. He ran an active life. Judt was considered a unique erudite because he knew French, German and Czech fluently. He was a historian who specialized in the latest European history, an author of the brilliant synthesis Postwar. A History of Europe Since 1945 and many other books. He was also a Professor at New York University, and Director of NYU’s Erich Maria Remarque Institute, a political commentator and an essayist. In his prime he fell ill with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s Disease, which he described with medical precision in his autobiography The Memory Chalet. Being confronted with terminal illness it is hard to find right words to describe this difficult position. The seriously ill searches for adequate comparisons and conceptual models. Tony Judt, like Ulla‑Carin Lindquist and Agata Tuszyńska, finds them in the semantics of the Holocaust. Judt confessed that the Holocaust was always close to his life. In the book Thinking the Twentieth Century he called himself “heir of the Holocaust”. In the latest statements of Judt one can find discreet traces of postmemory.
Utwory o matkach i córkach
Authors: Karolak Sylwia
Published: March 2018

From a large group of Polish postmemory literary texts, the author distinguishes a group that is considered to be significant and separate: Rodzinna historia lęku by Agata Tuszyńska, Utwór o Matce i Ojczyźnie by Bożena Keff, Włoskie szpilki by Magdalena Tulli oraz Frascati by Ewa Kuryluk. All these works were written by women. There are stories about complicated, often difficult and painful relations between mothers and daughters. It is important that these mothers are Polish Jewesses and Holocaust survivors. Their daughters represent the “second generation”. Fathers are absent in the lives of their daughters for many reasons (divorce, death, journey). This absence enables dialogue between the mother and her adult child, which helps shape the identity of the daughter and create the story about the Holocaust experience – the most important caesura and trauma in the mother’s life.
Między nieobecnością a obrazem

Published: March 2018

In the 50’s and 60’s France, the memory of the Occupation and the Holocaust was displaced from the official discourse and the social consciousness because of the ambiguous attitude of this country during the Second World War. It comes back in the contemporary French literature and culture since the 70’s, in the particular way within the problem of visuality: films, photographs and literary imagination. In relation to the Michel de Certeau’s and Paul Ricoeur’s thought, the author of the paper claims that memory, which is traditionally connected in the western culture to the image, should be rather considered as a tactical play with the representation of the past in historical discourse. Writers of the French “after‑generations”, who inherited the memory of the Holocaust, use this tactics not to represent the past, which would be its “treason”, as Paul Ricoeur says, but to influence and change the individual and social consciousness.

Published: March 2018

The Cape‑Verdean community is one of the most traditional and most important immigrant groups in Portugal. Since the first arrivals to the Portuguese land, the Cape‑Verdean people have settled in the Lisbon area. The cabo‑verdianos community actively participate in the artistic milieu of the multicultural Portuguese capital. Music has always been considered as one of the most relevant mechanisms of transmission of the Cape‑Verdean identity. The multiplicity of musical forms present both in the archipelago territory and in the Diaspora environment is a real proof of the creolization of the Cape‑Verdean culture. This paper aims to describe the interdependence between the musical creation of Cape‑Verdean immigrants (and especially the young Portuguese of Cape‑Verdean origins) and their searching for, re‑interpreting and defining the own cultural identity.

This paper aims to present how École Libre des Sciences Politiques in Paris affected the development of political sciences in Poland. Two schools based on the French model were set up in Cracow and Warsaw by Michał Rostworowski and Edmund Jan Reyman, former students of the French school. In this article, the Warsaw School of Political Sciences and the Jagiellonian University’s School of Political Sciences are described from the perspective adopted by Rostworowski in his study devoted to École Libre des Sciences Politiques. The paper describes the attempts to adapt the French model to the Polish conditions and shows two ways of its reception. The Warsaw school gained an academic status and became an all‑Polish centre of political sciences while the school in Cracow was incorporated into the Jagiellonian University and created an academic environment based on the master‑disciple relationship. It marked the beginning of what Marek Sobolewski described as the Cracow school of political sciences.

Published: March 2018

States have increasingly transitioned Medicaid enrollees with disabilities from fee-for-service (FFS) to Medicaid Managed Care (MMC), intending to reduce state Medicaid spending and to provide better access to health services. Yet, previous studies on the impact of MMC are limited and findings are inconsistent. We analyzed the impact of MMC on costs by tracking Illinois's Medicaid acute health services expenditures for adults with intellectual and developmental disabilities (IDD) living in the community (n = 1,216) before and after their transition to MMC. Results of the difference-in-differences (DID) regression analysis using an inverse propensity score weight (IPW) matched comparison group (n = 1,134) design suggest that there were no significant state Medicaid cost savings in transitioning people with IDD from FFS to MMC.

In the present scenario of bulk manufacturing where Metal Removal Rate (MRR), Chip Thickness Ratio (CTR) and Surface Roughness (SR) is of significant importance in manufacturing the component using CNC (computer numerical controlled) machines. Nine experiments were conducted based on orthogonal array. General linear model has been generated for all the three output parameters such as (MRR, Chip Thickness Ratio surface roughness) versus input parameters (speed, time, depth of cut). The statistical method called the analysis of variance (ANOVA) is applied to find the critical factor. The Main effects of S/N ratio values are found and plotted in the form of graph. The optimized value is found for speed, time, and depth of cut by using “MINITAB” software. By using this optimized value the efficient metal cutting can be done in commercial mild steel.

Cloud computing provides services that allocate infrastructure resources using the Internet as a medium and data storage on an external server. Small and medium corporations are the foundation of any flourishing economy for a growing nation which seeks new and innovative methods to reduce the way they manage their resources. Over a couple of decades, Information technology (IT) has created a significant impact in improving the lives of people and alsoon the global economy due to tremendous digital transformation. With the growth of the Small and medium corporations, IT is creating some real impact in enabling these industries to undergo adigital transformation of their business processes while they continue to grow. Small and medium enterprises (SME’s) are usually identified as the dominant force for the growth of any country's economy. In the cloud computing environment, the SME's need not have the in-house infrastructure so they can give up on any initial expenditure for setting up and instead they can utilize the resources available on the cloud and pay as per their requirement and usage.This paper presents the results of a comprehensive interpretation to research some of the most commonly used SaaS (Software-as-a-Service) implementations in the domain of Cloud Computing firstly to identify the weaknesses of the traditional computing approach for SME’s, and secondly to identify the aspects of these weaknesses that can be overcome by implementing cloud computing.In this paper, we provided the overview of various cloud computing models and literature survey of these models. This study extends to create an own cloud computing system for small and medium corporations. We will be using Software-as-a-Service (SaaS) approach and see how small and medium corporations can leverage on this for their business operations.

Published: March 2018

CAPTCHA is a Completely Automated Public Turing Test to tell Computers and Humans Apart [1]. Whenever a website is hosted onto a server it is not human that always tries to access the website. Sometimes a human generated computer bot also known as Zombie may try to access the website. In such situations bots need to be filtered from legitimate users and this can be accomplished by using a simple method called CAPTCHA. Initially CAPTCHA was developed on text-based platform later it was evolved to audio, image etc. In this paper a new technique to differentiate bots from humans is introduced. It is a question-based image-oriented technique where a question comprising of keywords is posed along with four different images out of which only one image has relation with all the keywords. The user needs to spot the image to pass the test. A flag will be counting the number of times the user failed the test and depending on the number of failure attempts the user is judged.

Secured dynamic path planning and multi-obstacle avoidance model for UAV networks
Authors: Prathyusha K , S. C. S. Sastry A
Published: March 2018

As the number of the obstacles are increasing along with the navigation paths, the security of the communication data also increasing exponentially in the dynamic UAV networks. A large number of path planning and obstacle avoidance models have been proposed on the static and dynamic UAV networks for data communication. Most of the traditional obstacle avoidance models are independent of security for communication data or path planning procedures. Since the UAV sensitive data are stored in each sensor along with the path planning information; there exists an unauthorized access or malicious access to the sensitive data from third party applications or users. Also, traditional standard cryptographic algorithms (both symmetric and asymmetric) are not efficient to provide complete security to vast amount of UAV data dynamically due to its high computational memory and time.In this paper, a novel trust based Ant Colony optimization model was proposed to secure the sensitive UAV data against unauthorized access. In this model, a novel cipher text policy based encryption and decryption procedure is used as an extension to KP-ABE for UAV path security. Experimental results proved that the proposed trust based optimization model is better than the traditional UAV security models in terms of computational time and memory.

Modulation diversity for differential amplitude and phase shift keying technique
Authors: Kanthimathi M , Amutha R , Anusha S
Published: March 2018

Modulation diversity can reduce the bit error rate in fading channels. We make use of the advantage of modulation diversity in non-coherent differential modulation technique. Increase in modulation diversity is obtained by rotating signal constellation. Coordinate interleaved Differential amplitude and phase-shift keying modulation (DAPSK) is particularly advantageous compared to the Differential phase-shift keying (DPSK) technique. Energy optimization is done to minimize the energy consumption. Simulation results shows that the proposed differential detection for different rotation angle achieves better BER performance than constant phase differential detection with modulation diversity.The energy required to successfully transmit a bit is also reduced for proposed system compared to Differential phase shift keying based system.

This method is proposed based on the original cuckoo search method. It was found in original cuckoo search the convergence speed is comparative lesser in reaching optimal solutions. To overcome the above mentioned problem one rank cuckoo search algorithm has been proposed which uses a bound by best solution technique to get the valid dimension so as to improve the system performance and rate of convergence. The proposed approach is applied to a four area hydro-thermal system in which area-1 and area-2 are steam reheat power plant and area-3 and area-4 are hydro power plant. The controller gains are derived using original cuckoo search and one rank cuckoo search methods. The superiority of the proposed approach is compared with the results obtained with original cuckoo search algorithm.

In this paper, state space model of the complete Wind Energy Electric Conversion System (WEECS) comprising of wind turbine, Permanent Magnet Synchronous Generator (PMSG), uncontrolled rectifier, DC-DC boost converter, and SPWM inverter feeding a standalone load has been formulated. The derived state space model is then simulated using Matlab/Simulink to test the model. As the standalone three phase load connected to the inverter demands constant output voltage irrespective of intermittent wind pattern, a PI controller is used to control the duty ratio of DC-DC boost converter to maintain constant output voltage at the inverter end.

The dangers phishing becomes considerably bigger problem in online networking, for example, Facebook, twitter and Google+. The phishing is normally completed by email mocking or texting and it frequently guides client to enter points of interest at a phony sites whose look and feel are practically indistinguishable to the honest to goodness. Non-technical user resists learning of anti-phishing technic. Also not permanently remember phishing learning. Software solutions such as authentication and security warnings are still depending on end user action.In this paper we are mainly focus on a novel approach of real time phishing email classification using K-means algorithm. For this we uses 160 emails of last year computer engineering students. we get True positive of legitimate and phishing as 67% and 80% and true negative is 30 % and 20%.,which is very high so we ask same users reasons which I mainly categories into three categories ,look and feel of email, email technical parameters, and email structure.

Authors: Shaikh Uzma , Paul Rajan Arokia
Published: March 2018

Mobile Ad-hoc Network (MANET) is a mobile network which has a large scale of self-directed nodes which is powerful to form a short-term means of communication network, without any use of prior communications. Due to its uniqueness like partial resources, varying loops and shortfall of controlling the networks, these networks are exposed to diverse network layer issues. The “Ad hoc on demand distance vector” is a self-starting directing procedure whose security is compromised with the distinct form of attack named as “Black-Hole” and “Grey Hole” attacks. This “malicious node” publicize as such, it contains the supreme track to the target during the route discovery process and thus interrupt the real communication and corrupt network performance. This paper introduces a new method in which a base node is introduced in the network that increases the probability of detecting multiple malicious nodes in the network and further separate them from taking part in any communication. It detects the corrupted nodes and prevent it by causing an effect for the communication. The proposed method has been experimented using NS2 and the results found to be efficient.

Reorganization of virtual machines (VM) presents an extraordinary opportunity for parallel, cluster, grid, cloud and distributed computing. Virtualization technology benefits the computing and IT ventures by enabling clients to share expensive by multiplexing virtual machines on a similar arrangement of hardware hosts. With the advantage of higher data-accessing feature, this data sharing approach provides challenges in perceptive to data security and data integrity issues. In this paper, to the selected network, a service level agreement approach for data access resource management is developed. During the exchange of packets over the selected link, it is required that data are to be accessed at a faster rate. The overhead may have serious negative effects on cluster utilization, throughput, and Quality of Service issues. Therefore, the challenge is to develop VMs a control approach, which governs the rate allocation in terms of data access and bandwidth to speed the data exchange performance. The throughput of the network is monitored by the traffic link rate, wherein the processing overhead is observed at the process of quality.

Online Social Networks(OSNs) have mutual themes such as information sharing, person-to-person interaction and creation of shared and collaborative content.  Lots of micro blogging websites available like Twitter, Instagram, Tumblr. A standout amongst the most prominent online networking stages is Twitter. It has 313 million months to month dynamic clients which post of 500 million tweets for each day. Twitter allows users to send short text based messages with up to 140-character letters called "tweets". Enlisted clients can read and post tweets however the individuals who are unregistered can just read them. Due to the reputation it attracts the consideration of spammers for their vindictive points, for example, phishing true blue clients or spreading malevolent programming and promotes through URLs shared inside tweets, forcefully take after/unfollow valid clients and commandeer drifting subjects to draw in their consideration, proliferating obscenity. Twitter Spam has become a critical problem nowadays. By looking at the execution of an extensive variety of standard machine learning calculations, fundamentally expecting to distinguish the acceptable location execution in light of a lot of information by utilizing account-based and tweet content-based highlights.

The methodology of inheriting the traditional townscape by “Re-use” the heritage buildings -Through sharing the case studies in Japan and India -
Authors: Ono Takashi
Published: March 2018

This paper is to share the experience in case studies of Japan and India through focusing on the succession of the townscape based on the architectural ‘re-use’. It has tended in Japan in recent years in order to solve the serious issue of the vacant residences in rural area.To begin with, based on the historian Kato’s idea, the architectural manner divides three things; re-use, re-development and restoration/conservation. He insists that the architectural manner and the value of re-use were replaced by two concept of "re-development" or "preservation" that suddenly appeared in modern but still effective.The researching place is selected following three cities; Obuse Town and Azumino City in Japan and Shimla in India. In case of Obuse, we made full use of existing properties of the town by re-using the space which has abandoned so far. And in case of Azumino, we can introduce the re-using building by changing the usage while utilizing the feature of the traditional houses.This paper just introduces the present situation of the architectural re-use of Shimla because we are going on the survey on the site, and the concrete analyzing will be discussed in the next paper.
