This paper describes quorum leases, a new technique that allows Paxos-based systems to perform reads with high throughput and low latency. Quorum leases do not sacrifice consistency and have only a small impact on system availability and write latency. Quorum leases allow a majority of replicas to perform strongly consistent local reads, which substantially reduces read latency at those replicas (e.g., by two orders of magnitude in wide-area scenarios). Previous techniques for performing localdoi:10.1145/2670979.2671001 dblp:conf/cloud/MoraruAK14 fatcat:hwkhqvffwjeatf4mkb2oksohre

We describe the design of quorum leases and evaluate their benefits compared to previous approaches through an implementation running in five geo-distributed Amazon EC2 datacenters.
This paper presents a new, memory efficient and cacheoptimized algorithm for simultaneously searching for a large number of patterns in a very large corpus. This algorithm builds upon the Rabin-Karp string search algorithm and incorporates a new type of Bloom filter that we call a feed-forward Bloom filter. While it retains the asymptotic time complexity of previous multiple pattern matching algorithms, we show that this technique, along with a CPU architecture aware design of the Bloom filter,doi:10.1145/2133803.2330085 fatcat:endhgdzmx5bl5hml3r3c7l7sxy

Industrial property and competition are indissoluble in terms of the legal manner in which the unfair competition act of confusion is committed. The regulation of confusion within the competition legislation of the Republic of Moldova (Law no. 183/2012 on Competition) is in an explicit connection relationship with industrial property, given the fact that the trademarks, industrial designs and other industrial property objects are protected through the provisions of the Law no. 183/2012 ondoaj:4af27dc837e34a06a08df466b6a0138e fatcat:da6qljbxcvei5f2n4jxi3y6rdq

In the same context, it is important to specify that under competition law are protected even industrial property objects that are not protected under industrial property division law. At the same time, in order to benefit from effective legal protection in accordance with the rules of unfair competition, there is a stringent need for a complex and effective bilateral evidentiary process. In order to validate the theoretical aspects stated above, the practice of the national competition authority of the Republic of Moldova (Competition Council) is essential.
This paper describes the design and implementation of Egalitarian Paxos (EPaxos), a new distributed consensus algorithm based on Paxos. EPaxos achieves three goals: (1) optimal commit latency in the wide-area when tolerating one and two failures, under realistic conditions; (2) uniform load balancing across all replicas (thus achieving high throughput); and (3) graceful performance degradation when replicas are slow or crash. Egalitarian Paxos is to our knowledge the first protocol to achievedoi:10.1145/2517349.2517350 dblp:conf/sosp/MoraruAK13 fatcat:55bawmaoifhqxgc6uumas7oasq

We prove Egalitarian Paxos's properties theoretically and demonstrate its advantages empirically through an implementation running on Amazon EC2.
We present the design and implementation of a novel anti-malware system called SplitScreen. SplitScreen performs an additional screening step prior to the signature matching phase found in existing approaches. The screening step filters out most non-infected files (90%) and also identifies malware signatures that are not of interest (99%). The screening step significantly improves end-to-end performance because safe files are quickly identified and are not processed further, and malware filesdoi:10.1109/jcn.2011.6157418 fatcat:3eqwwj5sbrd7foilznenjrpkme

Our approach naturally leads to a network-based anti-malware solution in which clients only receive signatures they needed, not every malware signature ever created as with current approaches. We have implemented SplitScreen as an extension to , the most popular open source anti-malware software. For the current number of signatures, our implementation is 2× faster and requires 2× less memory than the original ClamAV. These gaps widen as the number of signatures grows.
Discrediting competing trademarks consists in the spread of certain information regarding the trademarks owned by the competitor of the undertaking realising the disparaging actions. Relating the idea to the legislative provisions in force of the Republic of Moldova, it can be inferred that there are two options for qualifying such a conduct - according to the rules of unfair competition and in accordance with the rules of dishonest advertising. In such circumstances, the obvious questiondoi:10.53486/2537-6179.7-1.10 fatcat:tj644dvs6bfehaqveei4dlasaq

This aspect requires a broad clarification in the sense of offering viable alternative solutions and corresponding to the various practical factual situations. In this context, it is necessary to establish defined criteria in material and procedural terms in order to achieve a clear delimitation between different qualifying vectors. Circumstantially, there is a need to resort to the approach of domestic practice in this matter, as well as to the treatment of legislative, theoretical and practical trends in other states and legal systems.

Neuroendocrine tumors of the gastro-entero-pancreatic system have a variety of components, clinical manifestations and prognostic indices according to their anatomical site. Therefore, their diagnostic and management strategies differ a great deal. Prognosis concerning NETs can be poor due to the degree of differentiation, early metastasizing and the high degree of invasiveness.

There were 9 patients with NETs of the primite mid-and hindgut thusly: 5 cases with colorectal NETs and 4 cases of small bowel NETs. 6 patients benefited from radical surgical treatment, 2 cases with palliative procedures and only one patient with tumor biopsy. The tumors were evaluated according to the 2010 WHO classification based on the number of mitoses and the Ki67 proliferation index. Adjuvant treatment was adapted according to staging and histopathological parameters. Conclusions: Despite recent progress in managing NETs, there are still many controversial aspects regarding the management of these cases, mainly about timing the right sequence of therapy.

AbstractThe present paper discusses preliminary data on population characteristics and ecology of the meadow viper Vipera ursinii in the Romanian Danube Delta. Using line transects and the Distance software, the size of the studied population was estimated at 321 (95% confidence interval: 166–618) individuals on a 62 ha area. The sex-ratio of the population was close to 1:1 and juvenile specimens were well represented. Half of the captured adult females were gravid, possibly indicating a moredoi:10.2478/s11756-010-0146-z fatcat:lbqxutvuirdxjogrsdcihzycou

No significant relationships were detected between the size, sex, age or reproductive status and the thermal ecology of the vipers. Microhabitat selection and activity patterns varied with age, sex and reproductive status and are probably linked to an onthogenetic shift in feeding ecology and to behavioral differences between reproductive and non-reproductive females.
