A Structured Analysis of SQL Injection Runtime Mitigation Techniques

SQL injection attacks (SQLIA) still remain one of the most commonly occurring and exploited vulnerabilities. A considerable amount of research concerning SQLIA mitigation techniques has been conducted with the primary resulting solution requiring developers to code defensively. Although, defensive coding is a valid solution, the current market demand for websites is being filled by inexperienced developers with little knowledge of secure development practices. Unlike the successful case of ASLR, no SQLIA runtime mitigation technique has moved from research to enterprise use. This paper presents an in-depth analysis and classification, based on Formal Concept Analysis, of the 10 major SQLIA runtime mitigation techniques. Based on this analysis, one technique was identified that shows the greatest potential for transition to enterprise use. This analysis also serves as an enhanced SQLIA mitigation classification system. Future work includes plans to move the selected SQLIA runtime mitigation technique closer to enterprise use

Kan penge- og finanspolitikken under koronakrisen, bidra til oppbygging av bobletendenser i aktivamarkeder? : en empirisk studie av aksje- og boligmarkedet i Norge

Utredningen har som formål å undersøke om myndighetene sine penge- og finanspolitiske tiltak under koronakrisen, kan bidra til bobletendenser i aksje- og boligmarkedet. Pandemien har påført økonomien et kraftig tilbakeslag, og det har blitt innført ekstraordinære tiltak for å dempe konsekvensene av krisen. Samtidig har prisutvikling i både aksje- og boligmarkedet vært stigende under den pågående krisen. Dermed er det interessant å analysere påvirkningen de penge- og finanspolitiske tiltakene har hatt på markedene. For å besvare vår problemstilling, presenterer vi først historisk utvikling i aksje- og boligmarkedet. Der gjennomgår vi historiske kriser som har påvirket norske aktivamarkeder, og presenterer historisk prisutvikling i aksje- og boligmarkedet. Deretter presenterer vi koronakrisen, hvor vi illustrerer hvordan pandemien har påvirket realøkonomien, hvilke tiltak som er innført og utviklingen i aksje- og boligmarkedet. Videre har vi gjennomført en avviksanalyse av prisutviklingen i aksje- og boligmarkedet ved hjelp av HP-filter, hvor vi analyserte utviklingen både før og under koronakrisen. Videre analyserer vi prisutviklingen i aksje- og boligmarkedet i lys av fundamentale prisdrivere og forventninger. Deretter drøfter vi våre funn i lys av boble- og kriseteori for å vurdere om koronakrisen og de penge- og finanspolitiske tiltakene kan ha ført til forstyrrelse, overoppheting, bobletendenser og fremtidige trusler i aksje- og boligmarkedet. For å underbygge den empiriske analysen, gjennomfører vi også en komparativ analyse. Her sammenligner vi koronakrisen med tidligere kriser for å se om vi kan finne fellestrekk. Til slutt drøfter vi den komparative analysen i lys av kriseanatomi. På bakgrunn av våre analyser og drøftelser i denne utredningen, konkluderer vi med at de penge- og finanspolitiske tiltakene i stor grad har bidratt til overoppheting og bobletendenser i aksje- og boligmarkedet. Aksjemarkedet er preget av euforiske tilstander, der markedsprisingen avviker fra fundamental verdi på kort sikt. Boligmarkedet er derimot preget av ikke-euforiske tilstander, hvor fundamentale forhold forklarer boligprisutviklingen på kort sikt. På lengre sikt kan det foreligge en risiko for aktivainflasjon og bobleoppbygging. Dette er på bakgrunn av et pengeoverheng, som er et resultat av den betydelige tilførselen av likviditet til økonomien under pandemien.nhhma

Psychophysiological effects of synchronous versus asynchronous music during cycling

"This is a non-final version of an article published in final form in (https://journals.lww.com/acsm-msse/pages/articleviewer.aspx?year=2014&issue=02000&article=00024&type=abstract )"Purpose: Synchronizing movement to a musical beat may reduce the metabolic cost of exercise, but findings to date have been equivocal. Our aim was to examine the degree to which the synchronous application of music moderates the metabolic demands of a cycle ergometer task. Methods: Twenty-three recreationally active men made two laboratory visits. During the first visit, participants completed a maximal incremental ramp test on a cycle ergometer. At the second visit, they completed four randomized 6-min cycling bouts at 90% of ventilatory threshold (control, metronome, synchronous music, and asynchronous music). Main outcome variables were oxygen uptake, HR, ratings of dyspnea and limb discomfort, affective valence, and arousal. Results: No significant differences were evident for oxygen uptake. HR was lower under the metronome condition (122 T 15 bpm) compared to asynchronous music (124 T 17 bpm) and control (125 T 16 bpm). Limb discomfort was lower while listening to the metronome (2.5 T 1.2) and synchronous music (2.3 T 1.1) compared to control (3.0 T 1.5). Both music conditions, synchronous (1.9 T 1.2) and asynchronous (2.1 T 1.3), elicited more positive affective valence compared to metronome (1.2 T 1.4) and control (1.2 T 1.2), while arousal was higher with synchronous music (3.4 T 0.9) compared to metronome (2.8 T 1.0) and control (2.8 T 0.9). Conclusions: Synchronizing movement to a rhythmic stimulus does not reduce metabolic cost but may lower limb discomfort. Moreover, synchronous music has a stronger effect on limb discomfort and arousal when compared to asynchronous music

Cationic Polymers Inhibit the Conductance of Lysenin Channels

The pore-forming toxin lysenin self-assembles large and stable conductance channels in natural and artificial lipid membranes. The lysenin channels exhibit unique regulation capabilities, which open unexplored possibilities to control the transport of ions and molecules through artificial and natural lipid membranes. Our investigations demonstrate that the positively charged polymers polyethyleneimine and chitosan inhibit the conducting properties of lysenin channels inserted into planar lipid membranes. The preservation of the inhibitory effect following addition of charged polymers on either side of the supporting membrane suggests the presence of multiple binding sites within the channel's structure and a multistep inhibition mechanism that involves binding and trapping. Complete blockage of the binding sites with divalent cations prevents further inhibition in conductance induced by the addition of cationic polymers and supports the hypothesis that the binding sites are identical for both multivalent metal cations and charged polymers. The investigation at the single-channel level has shown distinct complete blockages of each of the inserted channels. These findings reveal key structural characteristics which may provide insight into lysenin’s functionality while opening innovative approaches for the development of applications such as transient cell permeabilization and advanced drug delivery systems

Interactions of the EU ETS with Green And White Certificate Schemes: European Commission Directorate-General Environment

The European Union Emissions Trading Scheme ('EU ETS') began on 1 January 2005. The implementation of the EU ETS has raised interest in market-based approaches to achieving environmental and related public policy goals in the EU, particularly those related to promotion of renewable energy and energy efficiency. Indeed, national and regional markets in tradable green certificates ('TGCs') and (to a lesser extent) tradable white certificates ('TWCs') already exist. Green certificate schemes are established or proposed in a number of Member States (e.g., Belgium, the Czech Republic, Denmark, France, Italy, the Netherlands, Sweden and the UK) and form part of a growing portfolio of measures to achieve the renewable targets outlined in Directive 2001/77/EC. White certificate schemes are considerably less widespread, although schemes have been established in Italy and the UK and further activity may be stimulated by the Commission proposal on energy services (COM(2003)739). Both the renewables Directive and the energy services proposal envisage the possible evolution and harmonisation of these instruments into EU-wide certificate schemes. This study has two major objectives: -1. Analyse interactions among EU ETS and green/white certificate markets. The first major objective is to describe the interactions between green and white certificate programmes and the EU ETS. -2. Assess implications of interactions for the policy objectives of the EU ETS. The second major objective deals with the implications of green/white certificate programmes for the objectives of the EU ETS

A feasibility study into the production of a mussel matrix reference material for the cyanobacterial toxins microcystins and nodularins.

Microcystins and nodularins, produced naturally by certain species of cyanobacteria, have been found to accumulate in aquatic foodstuffs such as fish and shellfish, resulting in a risk to the health of the seafood consumer. Monitoring of toxins in such organisms for risk management purposes requires the availability of certified matrix reference materials to aid method development, validation and routine quality assurance. This study consequently targeted the preparation of a mussel tissue reference material incurred with a range of microcystin analogues and nodularins. Nine targeted analogues were incorporated into the material as confirmed through liquid chromatography with tandem mass spectrometry (LC-MS/MS), with an additional 15 analogues detected using LC coupled to non-targeted high resolution mass spectrometry (LC-HRMS). Toxins in the reference material and additional source tissues were quantified using LC-MS/MS, two different enzyme-linked immunosorbent assay (ELISA) methods and with an oxidative-cleavage method quantifying 3-methoxy-2-methyl-4-phenylbutyric acid (MMPB). Correlations between the concentrations quantified using the different methods were variable, likely relating to differences in assay cross-reactivities and differences in the abilities of each method to detect bound toxins. A consensus concentration of total soluble toxins determined from the four independent test methods was 2425 ± 575 µg/kg wet weight. A mean 43 ± 9% of bound toxins were present in addition to the freely extractable soluble form (57 ± 9%). The reference material produced was homogenous and stable when stored in the freezer for six months without any post-production stabilization applied. Consequently, a cyanotoxin shellfish reference material has been produced which demonstrates the feasibility of developing certified seafood matrix reference materials for a large range of cyanotoxins and could provide a valuable future resource for cyanotoxin risk monitoring, management and mitigation

The Prevalence and Correlation of Non-motor Symptoms in Adult Patients with Idiopathic Focal or Segmental Dystonia

Background: Idiopathic focal dystonia is a motor syndrome associated with dysfunction of basal ganglia circuits. Observations have suggested that many other non-motor symptoms may also be part of the clinical picture. The aim was to assess the prevalence and correlation of non-motor symptoms in patients with common idiopathic focal or segmental dystonia. Methods: In a single-center cross-sectional case–control study, we evaluated the presence of pain, neuropsychiatric symptoms, and sleep alterations in 28 patients with blepharospasm, 28 patients with cervical dystonia, 24 patients with writer’s cramp, and 80 control subjects matched for sex, age, and schooling. We obtained clinical and demographic data, and evaluated patients using the Fahn–Marsden Dystonia Rating Scale and other specific scales for dystonia. All subjects completed the following questionnaires: Beck Depression Inventory, Beck Anxiety Inventory, Social Phobia Inventory, Apathy Scale, Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, Brief Pain Scale, and the World Health Organization Quality of Life brief scale. Results: The patients presented more symptoms of depression, anxiety, and apathy than the control subjects. They also reported worse quality of sleep and more pain complaints. Patients with blepharospasm were the most symptomatic subgroup. The patients had worse quality of life, and the presence of pain and symptoms of apathy and depression were the main influences for these findings, but not the severity of motor symptoms. Discussion: Patients with dystonia, especially those with blepharospasm, showed higher prevalence of symptoms of depression, anxiety, apathy, worse quality of sleep, and pain. These symptoms had a negative impact on their quality of life

Real‐time biofeedback integrated into neuromuscular training reduces high‐risk knee biomechanics and increases functional brain connectivity: A preliminary longitudinal investigation

Prospective evidence indicates that functional biomechanics and brain connectivity may predispose an athlete to an anterior cruciate ligament injury, revealing novel neural linkages for targeted neuromuscular training interventions. The purpose of this study was to determine the efficacy of a real‐time biofeedback system for altering knee biomechanics and brain functional connectivity. Seventeen healthy, young, physically active female athletes completed 6 weeks of augmented neuromuscular training (aNMT) utilizing real‐time, interactive visual biofeedback and 13 served as untrained controls. A drop vertical jump and resting state functional magnetic resonance imaging were separately completed at pre‐ and posttest time points to assess sensorimotor adaptation. The aNMT group had a significant reduction in peak knee abduction moment (pKAM) compared to controls (p = .03, d = 0.71). The aNMT group also exhibited a significant increase in functional connectivity between the right supplementary motor area and the left thalamus (p = .0473 after false discovery rate correction). Greater percent change in pKAM was also related to increased connectivity between the right cerebellum and right thalamus for the aNMT group (p = .0292 after false discovery rate correction, r2 = .62). No significant changes were observed for the controls (ps > .05). Our data provide preliminary evidence of potential neural mechanisms for aNMT‐induced motor adaptations that reduce injury risk. Future research is warranted to understand the role of neuromuscular training alone and how each component of aNMT influences biomechanics and functional connectivity.Emergent evidence indicates that the risk of anterior cruciate ligament (ACL) injury is, in part, due to central nervous system alterations that could be targeted using neural mechanistic sensorimotor‐based treatments. Young female athletes completed 6 weeks of neuromuscular training while interacting with a real‐time, visual biofeedback stimulus. Our training was designed to reduce the risk of by (a) promoting injury‐resistant movement and (b) strengthening brain functional connectivity. Our data not only indicated that athletes’ biomechanics and brain connectivity were improved following training, but the observed biomechanical improvements were related to distinct, strengthened connectivity within regions important for sensorimotor control. This study supports the use of real‐time biofeedback systems to reduce the risk of ACL injury by leveraging neuroplasticity.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154933/1/psyp13545_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154933/2/psyp13545.pd
