We prove that for k ≫; 4√n regular resolution requires length nω(k) to establish that an ErdÅ's-Rényi graph with appropriately chosen edge density does not contain a k-clique. This lower bound is optimal up to the multiplicative constant in the exponent and also implies unconditional nω(k) lower bounds on running time for several state-of-the-art algorithms for finding maximum cliques in graphs.
In order to find out whether an interval appendectomy is necessary after an appendicitis with a palpable mass, we retrospectively studied the reports of 50 patients who underwent an interval appendectomy. Out of the 50 patients 5 (10%) developed complications of the appendiceal mass. Intraoperative findings of the interval appendectomy: 32 (64%) had adhesions; 2 (4%) appendices were resorbed; 2 (4
We prove that unary Sherali-Adams requires proofs of size nΩ(d) to rule out the existence of an nΘ(1)-clique in Erdős-Rényi random graphs whose maximum clique is of size d ≤ 2 log n. This lower bound is tight up to the multiplicative constant in the exponent. We obtain this result by introducing a technique inspired by pseudo-calibration which may be of independent interest. The technique involves

We present a theoretical investigation of a model clay dispersion in 1-1 salt solutions by varying the particle volume fraction and ionic strength as well as the charge distribution on the clay platelets. The platelets are modeled as discs with charged sites distributed on a hexagonal lattice. The edge sites can be positively charged while the remaining sites are negative giving rise to a strong c
This paper focuses on the distributed non-Bayesian quickest change detection based on the Cumulative Sum (CUSUM) algorithm in an energy harvesting wireless sensor network (WSN), where the distributions before and after the change point are assumed to be known. Each sensor is powered by randomly available harvested energy from the surroundings. It samples the observation signal and computes the log
Radiocarbon analysis of the carbonaceous aerosol allows an apportionment of fossil and non-fossil sources of airborne particulate matter (PM). A chemical separation of total carbon (TC) into its subfractions organic carbon (OC) and elemental carbon (EC) refines this powerful technique, as OC and EC originate from different sources and undergo different processes in the atmosphere. Although C-14 an
Certain monoclonal antibodies (mAbs) to type II collagen (CII) induce arthritis in vivo after passive transfer and have adverse effects on chondrocyte cultures and inhibit self assembly of collagen fibrils in vitro. We have examined whether such mAbs have detrimental effects on pre-existing cartilage. Bovine cartilage explants were cultured over 21 days in the presence of two arthritogenic mAbs to
A comparative in vitro survey of physiologically relevant human and microbial proteinases defined a number of enzymes that induced specific hinge domain cleavage in human IgG1. Several of these proteinases have been associated with tumor growth, inflammation, and infection. A majority of the identified proteinases converted IgG to F(ab')(2), and a consistent feature of their action was a transient
Background: Malaria kills almost 1 million people every year, but the mechanisms behind protective immunity against the disease are still largely unknown. Methodology/Principal Findings: In this study, surface plasmon resonance technology was used to evaluate the affinity (measured as kd) of naturally acquired antibodies to the Plasmodium falciparum antigens MSP2 and AMA1. Antibodies in serum samp
Purpose: The purpose of this thesis is to provide an understanding of how consumer-brand relationships are affected by a radical rebranding strategy of a football club’s logo. This further leads the paper to contribute to the literature of consumer-brand relationships in the special context of football. Methodology: The interpretative nature of this research calls for a qualitative research appro

Sagem Défense et Sécurité (now Safran Electronics & Defense), a French space and defense company of the SAFRAN group, is working on the next generation of Unmanned Aerial System (UAS). This UAS features a fully automatic Unmanned Aerial Vehicle (UAV) equipped with a state-of-the-art navigation system. This navigation system relies mainly on a high-accuracy Inertial Measurement Unit (IMU) coupl
This study showcases an integrative mass spectrometry-based strategy combining systems antigenomics and systems serology to characterize human antibodies in clinical samples. This strategy involves using antibodies circulating in plasma to affinity-enrich antigenic proteins in biochemically fractionated pools of bacterial proteins, followed by their identification and quantification using mass spe
