As browser vendors have extended functionality and support to new technologies, security researchers and hackers are continuously looking for new vulnerabilities. In this talk, Roberto and Scott will share results of their assiduous browser bug hunting. The talk will examine techniques used to discover critical and less severe vulnerabilities in some of the most popular browsers on the market.

Livestock-Climate Change Annual Meeting 2011: REMM Project Update (R. Reid)Colorado State University
A description of the Livestock-Climate Change CRSP's REMM Project (Increasing adaptive capacity of Mongolian livestock herders under a changing climate through rangeland ecosystem monitoring and community-based conservation) and update on the project's current status. Presentation given by R. Reid (Colorado State University) at the Livestock Climate Change CRSP Annual Meeting, Golden, CO, April 26-27, 2011.
A lo largo de estas jornadas, expertos nacionales e internacionales en el tema analizarán la situación actual, tendencias futuras y principales retos que plantean los esquemas de reducción de emisiones y los mercados de carbono como herramientas en la lucha contra el calentamiento global, especialmente después de la cumbre de Copenhague.

Economic pressures and competition have created a need for superior performance and multifunctional properties of materials. The ever-increasing demand for new product properties makes it challenging to achieve the required features when using traditional materials. Therefore, new material combinations (i.e. hybrid or composite materials) are intended to meet these challenges. Composites and hybrid materials are new material combinations which can provide added value for existing products or create novel multifunctional properties.
This thesis aimed at fabricating and modifying thin-film composites (TFC) by using various coating technologies. Moreover, the target was to tailor the permeability or to create anti-fouling performance. Inorganic, inorganic-organic and organic coating layers were made by atmospheric plasma deposition, sol-gel, atomic-layerdeposition (ALD) or polyvinyl alcohol (PVA) dispersion coating methods. Coatings were deposited using either roll-to-roll or batch process.
The scientifically novel contribution of this thesis is as follows. The thesis contributes to the development of novel TFC structures using various coating methods. The novel TFC structures provide new alternatives or improvements for the existing barrier materials in food packaging. In addition, the developed anti-fouling coatings tackle the critical challenge of membrane fouling and introduce new low-fouling TFC membranes for water treatment.

Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.
As Europe's leading economic powerhouse and the fourth-largest hashtag#economy globally, Germany stands at the forefront of innovation and industrial might. Renowned for its precision engineering and high-tech sectors, Germany's economic structure is heavily supported by a robust service industry, accounting for approximately 68% of its GDP. This economic clout and strategic geopolitical stance position Germany as a focal point in the global cyber threat landscape.
In the face of escalating global tensions, particularly those emanating from geopolitical disputes with nations like hashtag#Russia and hashtag#China, hashtag#Germany has witnessed a significant uptick in targeted cyber operations. Our analysis indicates a marked increase in hashtag#cyberattack sophistication aimed at critical infrastructure and key industrial sectors. These attacks range from ransomware campaigns to hashtag#AdvancedPersistentThreats (hashtag#APTs), threatening national security and business integrity.
🔑 Key findings include:
🔍 Increased frequency and complexity of cyber threats.
🔍 Escalation of state-sponsored and criminally motivated cyber operations.
🔍 Active dark web exchanges of malicious tools and tactics.
Our comprehensive report delves into these challenges, using a blend of open-source and proprietary data collection techniques. By monitoring activity on critical networks and analyzing attack patterns, our team provides a detailed overview of the threats facing German entities.
This report aims to equip stakeholders across public and private sectors with the knowledge to enhance their defensive strategies, reduce exposure to cyber risks, and reinforce Germany's resilience against cyber threats.

Abstract
The 6th international Symposium on Ecosytem Behaviour, BIOGEOMON 2009, is held at Helsinki,
Finland, in June 29th –July 3rd 2009. BIOGEOMON’s primary goals are to provide a forum for the
dissemination and discussion of recent research findings, to explore future directions for biogeochemi-
cal research, and to foster interdisciplinary collaboration between researchers of all ages and countries.
There were altogether over 400 registrated participants representing 32 different countries, including
both internationally renowned scientists and postgraduate students.The meeting was hosted by The
Finnish Forest Research Institute (Metla), the University of Helsinki, and the Finnish Environment
Institute (SYKE) in association with the Czech Geological Survey (CR), Villanova University (USA),
the University of Reading (UK) , the Geological Survey of Finland (GTK), and the Finnish Meteoro-
logical Institute (FMI). The information presented by the speakers during the meeting sessions, as well
as by the numerous posters is collected into this publication in the form of abstracts. BIOGEOMON’s
emphasis is on biogeochemistry as an evolving and integrated discipline, including research at the
watershed, landscape and global scales. Beside traditionally emphasized themes, topical issues are
raised in each BIOGEOMON symposium. In Helsinki these issues are peatland biogeochemistry,
environmental impacts of bioenergy production, atmosphere – forest interactions, and biogeochemistry
of trace metals.
