The use of probiotics in animal feeding for safe production and as potential alternatives to antibiotics
Venue: Veterinary world
Year: 2021

Although the production of safe food for human consumption is the primary purpose for animal rearing, the environment and well being of the animals must also be taken into consideration. Based on microbiological point of view, the production of healthy food from animals involves considering foodborne pathogens, on the one hand and on the other hand, the methods used to fight against germs during breeding. The conventional method to control or prevent bacterial infections in farming is the use antibiotics. However, the banning of these compounds as growth promoters caused many changes in animal breeding and their use has since been limited to the treatment and prevention of bacterial infections. In this function, their importance no longer needs to be demonstrated, but unfortunately, their excessive and abusive use have led to a double problem which can have harmful consequences on consumer health: Resistance to antibiotics and the presence of antibiotic residues in food. The use of probiotics appears to be a suitable alternative to overcome these problems because of their ability to modulate the immune system and intestinal microflora, and further considering their antagonistic role against certain pathogenic bacteria and their ability to play the role of growth factor (sometimes associated with prebiotics) when used as feed additives. This review aims to highlight some of the negative effects of the use of antibiotics in animal rearing as well as emphasize the current knowledge on the use of probiotics as a feed additive, their influence on animal production and their potential utility as an alternative to conventional antibiotics, particularly in poultry, pig, and fish farming.
More of the same: Synthesizing a variety by structural layering
Venue: Comput. Graph.
Year: 2012

Highly detailed natural scenes and objects tend to be perceived as being realistic, while repeated parts and patterns decrease their realism. To avoid scenes with noticeable repeated elements, we introduce the notion of 'more of the same' which focuses on the task of generating additional similar instances from a small set of exemplars. The small number of exemplars, as well as their diversity and detailed structural texture, makes it difficult to apply statistical methods, or other machine learning tools, and thus more specialized tools need to be used. In this paper, we focus on generating a rich variation of highly detailed realistic leaves from just a handful set of examples. The method that we present does use only minimal domain specific knowledge and requires only minimal user assistance applied on a single training leaf exemplar to extract and separate structural layers. The knowledge from one leaf is then transferred to the other exemplars by a novel color/spatial layer inducing algorithm. The premise of structural layering is that each set of layers is simple enough to be synthesized separately and then composed into a novel leaf structural texture. This composition also allows the synthesis of slightly modified layers from the set of examples, which can generate a large set of differently looking leaves. We demonstrate numerous results of realistically looking leaves produced by our method from a small set of leaves.
The significance of tumour deposits in rectal cancer after neoadjuvant therapy: a systematic review and meta analysis.
Venue: European journal of cancer
Year: 2019

Tumour deposits (TDs) are a poor prognostic marker in colorectal cancer, but their significance after neoadjuvant chemoradiotherapy is less certain because this group of patients is excluded in most studies. Post treatment TD might even be a sign of tumour response. No previous reviews have assessed outcomes in this group.  A systematic review and meta analysis was undertaken according to Preferred Reporting for Systematic Reviews and Meta Analyses guidelines to determine the relevance of post treatment TD. Inclusion criteria were studies assessing TD in patients who had undergone pre operative treatment with radiotherapy and/or chemotherapy and reporting prevalence and survival outcomes. Studies that did not include histological review of cases were excluded.  Eight studies and 1283 patients were included in the review. Prevalence of TDs varied from 11.8% to 44.2% (mean 23.7% similar to untreated patients. The presence of TDs after chemoradiotherapy was associated with invasion depth, lymph node involvement, perineural invasion and synchronous metastases. The pooled hazard ratio for 5 year adverse disease free survival was 2.3 (95% confidence interval [CI] 1.8 2.9) and that for overall survival was 2.5 (95% CI: 1.9 3.3) One study showed a survival benefit with adjuvant therapy in the TD positive group.  In analogy with untreated patients, the presence of TDs in patients with rectal cancer after neoadjuvant treatment is associated with advanced disease and a poor outcome.
The Sahel Crisis:Where do European and AfricanPerspectives Meet? IES Policy Brief Issue 2013/02/March 2013
Year: 2013

The crisis in Mali has brought the Sahel to the centre of international attention. This fragile region not only suffers from longstanding development challenges, but also from an acute security vacuum that has triggered military intervention. Many questions have arisen as a consequence of the crisis. Has the European Union the ability to cope with such a complex and dynamically evolving security environment? How have divergent views on the political roadmap to be adopted, and the lack of resources at the African level, impacted the crisis response? Can the different players involved agree on what are the most pertinent needs and challenges to be addressed? Are they ready for long term engagement? Can regional organisations effectively collaborate and are they able to successfully integrate different agendas? Following a conference organised by the Institute for European Studies, the Egmont Institute and the Observatoire de l'Afrique on these questions this Policy Brief builds on the findings of the conference and provides an analytical overview of the regional crisis by focusing on the main challenges facing the Sahel, the local and regional dynamics at play and the military and security response.
FREEDOM OF EXPRESSION IN SOCIAL MEDIA AND CRIMINALIZATION OF HATE SPEECH IN SPAIN: EVOLUTION, IMPACT AND EMPIRICAL ANALYSIS OF NORMATIVE COMPLIANCE AND SELF CENSORSHIP
Year: 2020

The popularization of social media as a forum for the expression of ideas and for political debate has increased in recent years the, always present, tension between freedom of expression and public control of offensive or dangerous speech. Many democratic states criminalise hate speech and other types of offensive expression, and now are social Media themselves that can exercise prior censorship over content on the basis of similar rules but much more restrictive and ambiguous. Combining normative analysis with empirical methodologies, this paper analyses, focusing on Spain, the implications that Criminal laws and "community guidelines" have on citizens' decisions to express themselves freely, which is fundamental for the configuration of a real democracy. It is made up of two studies: the first traces the evolution of judicial resolutions in Spain that prosecute possible crimes of terrorism and hate for political expression on social networks, as a result of the popularisation of these since 2014 in concurrence with a broad and ambiguous legislation. The results show a significant growth of state control over expressions that are essentially offensive but that, in most cases, do not represent a clear and present danger and could go beyond the doctrine of the ECHR. In the second part, an empirical study is carried out to analyse how the existence of hate speech crimes and social media rules affects the decision to express political ideas on social networks or to self censor. The results show that a large part of the sample is self censoring but that criminal law and content rules, in particular the severity of the law and the certainty that it is applied, do not have a direct effect on the decision to express ideas on the Internet, while the social perception of what others do is decisive. It is discussed how this calls into question the legitimacy of the evident limitation of freedom of expression of some crimes in Spain.

The proposed control algorithm is capable of driving the tractor trailer system to any desired trajectory ensuring high control accuracy and robustness against environmental disturbances.
Effects of Customer Participation Level on Customers' Attributions, Emotions, and Behaviors in Case of Internet Service Failure
Venue: 2009 Fifth International Joint Conference on INC, IMS and IDC
Year: 2009

This study explores the impact of two factors that are prominent in the marketing literature: customer participation and service failure. We here conducted a empirical test to show how customers' perceived level of participation influences their attribution tendency and emotional/behavioral responses toward service failure which they may encounter on internet. According to the results of analysis, customers whose perceived level of participation in service production and delivery is high showed external attribution tendency more, felt disappointment more, and wanted to complain, switch, and communicate negative WOM more than those with low participation perception. The results imply that strategies to blindly raise customer participation should be reconsidered. Internet based service firms should organize their service procedures easily and simply to reduce customers time and efforts(physical input) They also should design their web sites more interestingly in order to provide pleasant experiences to customers. And they should be careful not to request unnecessary information provision from customers (informational input) In addition, service providers on internet should prepare devices with which customers can complain easily when they experience service failure.
Identifying Specific Cues and Contexts Related to Smoking Craving for the Development of Effective Virtual Environments
Venue: Cyberpsychology Behav. Soc. Netw.
Year: 2011

Craving is considered the main variable associated with relapse after smoking cessation. Cue Exposure Therapy (CET) consists of controlled and repeated exposure to drug related cues with the aim of extinguishing craving responses. Some virtual reality (VR) environments, such as virtual bars or parties, have previously shown their efficacy as tools for eliciting smoking craving. However, in order to adapt this technology to smoking cessation interventions, there is a need for more diverse environments that enhance the probability of generalization of extinction in real life. The main objective of this study was to identify frequent situations that produce smoking craving, as well as detecting specific craving cues in those contexts. Participants were 154 smokers who responded to an ad hoc self administered inventory for assessing craving level in 12 different situations. Results showed that having a drink in a bar/pub at night, after having lunch/dinner in a restaurant and having a coffee in a cafe or after lunch/dinner at home were reported as the most craving inducing scenarios. Some differences were found with regard to participants' gender, age, and number of cigarettes smoked per day. Females, younger people, and heavier smokers reported higher levels of craving in most situations. In general, the most widely cited specific cues across the contexts were people smoking, having a coffee, being with friends, and having finished eating. These results are discussed with a view to their consideration in the design of valid and reliable VR environments that could be used in the treatment of nicotine addicts who wish to give up smoking.
In situ full field mapping of melt flow dynamics in laser metal additive manufacturing
Year: 2020

Melt flow plays a critical role in laser metal additive manufacturing, yet the melt flow behavior within the melt pool has never been explicitly presented. Here, we report in situ characterization of melt flow dynamics in every location of the entire melt pool in laser metal additive manufacturing by populous and uniformly dispersed micro tracers through in situ high resolution synchrotron x ray imaging. The location specific flow patterns in different regions of the melt pool are revealed and quantified under both conduction mode and depression mode melting. The physical processes at different locations in the melt pool are identified. The full field melt flow mapping approach reported here opens the way to study the detailed melt flow dynamics under real additive manufacturing conditions. The results obtained provide crucial insights into laser additive manufacturing processes and are critical for developing reliable high fidelity computational models.

A Model of Role Risk Based Intrusion Prevention for Cloud Environment
Venue: 2018 14th International Wireless Communications Mobile Computing Conference (IWCMC)
Year: 2018

Cloud computing is a distributed and dynamic computing model that still has many difficulties. Intrusion prevention based on access control is an essential research challenge to better ensure the security of the cloud network. The flexibility and the scalability of the application of access control are the essential issues in a cloud environment. This paper proposes the use of risk and role based dynamic access control for preventing intrusions targeting the cloud computing, where the main enhancement of the proposed procedure is that access decision is mainly based on the resources available in the cloud services providers. The proposed scheme get the access decision based on a mixture of eXtensible Access Control Markup Language (XACML) decisions, risk analysis, and vulnerabilities assessment. Experimental results based on a comparison with related work are also presented to show the efficiency of the proposed approach.
A Phase I Study of CPI 613 in Combination with High Dose Cytarabine and Mitoxantrone for Relapsed or Refractory Acute Myeloid Leukemia
Venue: Clinical Cancer Research
Year: 2018

CPI 613, a lipoate analogue that inhibits pyruvate dehydrogenase (PDH) and a ketogluterate dehydrogenase (KGDH) has activity in patients with myeloid malignancies. This study explored the role of mitochondrial metabolism in chemotherapy response and determined the MTD, efficacy, and safety of CPI 613 combined with high dose cytarabine and mitoxantrone in patients with relapsed or refractory acute myeloid leukemia.  The role of mitochondrial response to chemotherapy was assessed in cell lines and animal models. A phase I study of CPI 613 plus cytarabine and mitoxantrone was conducted in patients with relapsed or refractory AML.  Exposure to chemotherapy induced mitochondrial oxygen consumption that depended on PDH. CPI 613 sensitized AML cells to chemotherapy indicating that mitochondrial metabolism is a source of resistance. Loss of p53 did not alter response to CPI 613. The phase I study enrolled 67 patients and 62 were evaluable for response. The overall response rate was 50% (26CR+5CRi/62) Median survival was 6.7 months. In patients over 60 years old, the CR/CRi rate was 47% (15/32) with a median survival of 6.9 months. The response rate for patients with poor risk cytogenetics also was encouraging with 46% (11/24 patients) achieving a CR or CRi. RNA sequencing analysis of a subset of baseline bone marrow samples revealed a gene expression signature consistent with the presence of B cells in the pretreatment marrow of responders.  The addition of CPI 613 to chemotherapy is a promising approach in older patients and those with poor risk cytogenetics.

Venue: 2019 International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob)
Year: 2019

The development of innovative applications for smart cities has been made possible by the rise of Internet of Things. The situational viewing and surveillance in cities is one such category of applications which can benefit from various networking solutions available to transport images or data from installed sensor cameras. In this paper, we propose and evaluate a citywide image and data collection service based on Vehicular Delay Tolerant Networks (VDTN) and a simple hierarchical routing mechanism named Data Collection for Low Energy Devices (DC4LED) We study the networking performance in terms of increasing image sizes that can be transported with respect to varying vehicular density in city. We focus mainly on two technologies for sensors to vehicles communications: ZigBee and ITS G5.
Development of Speaking Skills through Activity Based Learning at the Elementary Level
Year: 2017

This paper discusses an effective instructional method called 'activity based learning' that can be used to develop the speaking skills of students in the elementary school level. The present study was conducted to determine the effect of activity based learning on the development of the speaking skills of low and high achievers in a 6th grade class at the elementary school level.  The research was based on pre test post test equivalent group design. A total of 50 male students served as participants in this research. The participants were selected randomly from two sections and then a pre test was administered. Based on pre test scores, the participants were divided equally into experimental and control groups. High and low score achievers in each group were also identified. The experimental group received instruction based on the activity based learning method, and the control group was instructed through the traditional language teaching method. At the end of the experiment, a post test was administered to measure the development of speaking skills in students. The independent sample t test was used to test the significance of difference between the mean scores of groups at the 0.05 level. Implications for Research and Practice: The findings of the study suggested that activity based learning was an effective way to enhance students' speaking skills since the experimental group post test score was significantly different from the control group post test score. Based on the result of the study, it is recommended that the activity based learning method be used in class to develop and enhance the speaking skills of students. It is also recommended that teachers be provided training to implement the activity based method in language lessons.
Introducing prescribed biases in out of equilibrium Markov models
Year: 2017

Markov models are often used in modeling complex out of equilibrium chemical and biochemical systems. However, many times their predictions do not agree with experiments. We need a systematic framework to update Markov models to make them consistent with constraints that are derived from experiments. Here, we present a framework based on the principle of maximum path entropy to update Markov models using stationary state and dynamical trajectory based constraints. We illustrate the framework using a biochemical model network of growth factors based signaling. We also show how to find the closest detailed balanced Markov model to a given Markov model. Further applications and generalizations are discussed.
