New Mesolithic Hunting Evidence from Bone Injuries at Danish Maglemosian Sites: Lundby Mose and Mullerup (Sjælland)

The recent re-analysis of the Maglemosian faunal assemblages from Mullerup and Lundby Mose (Sjaelland) has led to the discovery of new hunting injuries in the Danish Early Mesolithic. In total, including the two cases already published, two examples come from the Lundby Mose site, and seven from Mullerup, including embedded flint fragments and perforations. Such new data emphasise the need for meticulous re-analysis of bone assemblages, relying on experimental work on projectile impacts, in order to increase the number of such discoveries. The link with weapons and hunting techniques and the question of the frequency of projectile impacts during the Danish Mesolithic are discussed, as well as their significance in terms of mobility of human groups, particularly in the case of healed wounds.

The Effect of Home-Based Resistance Exercise in Overweight and Obese Adults.

PURPOSE: The purpose of this study was to examine the changes in muscular strength, physical function and health-related quality of life (HRQOL) with the addition of resistance training to a 12 week behavioral weight loss intervention in overweight and obese adults. METHODS: Forty-eight overweight adults (body mass index = 33.3i? ½3.5 kg/m2) participated in this study. Thirty-eight subjects completed the 12 week behavioral weight loss intervention consisting of weekly behavioral counseling and weekly exercise sessions. Twenty-two subjects completed the 12 week standard behavioral weight loss intervention (SBWI) and sixteen subjects completed the 12 week home-based resistance exercise program (HBRE). The following measurements were performed at baseline and again at week 12: body weight, body mass index, body composition, muscular strength (1 RM chest press and 1 RM leg extension), physical function and HRQOL. RESULTS: A repeated measures ANOVA showed that there were significant decreases from baseline to week 12 for body weight, body mass index, lean body mass, and percent body fat. Measures of physical function showed improvement in step-up time, walk test time, chair rise time, and single leg balance time. There was a significant reduction in absolute upper body muscular strength, with no significant change in absolute lower body muscular strength. There were significant improvements is subscales of HRQOL for role physical, vitality, and general health (p<0.05), with a trend towards improvement in physical functioning (p=0.07). There were no significant differences in the pattern of change in any of the outcome measures between SBWI and HBRE. However, compliance to prescribed resistance exercise was approximately 40% of prescribed exercise days for HBRE. CONCLUSION: Overall, this investigation produced positive changes from baseline to week 12 in the outcome variables of weight, body composition, physical function, and HRQOL. Resistance exercise did not further improve these outcomes compared to what was achieved with a non-resistance exercise behavioral weight loss intervention. This may have been a result of less than optimal compliance to the resistance exercise training aspect of the intervention in HBRE. These results imply that the addition of resistance training to a standard behavioral weight loss program offers no increased benefit in the variables of interest, possibly resulting from low compliance, and future studies should examine strategies to improve the compliance to resistance exercise in overweight adults undertaking a behavioral weight loss intervention.

Algorithm Development of a Visibility Monitoring Technique Using Digital Image Analysis

Atmospheric visibility is one of the indicators used to evaluate the status of air quality. Based on a conceptual definition of visibility as the maximum distance at which the outline of the selected target can be recognized, an image analysis technique is introduced here and an algorithm is developed for visibility monitoring. Although there are various measurement techniques, ranging from bulk and precise instruments to naked eye observation techniques, each has their own limitations. In this study, a series of image analysis techniques were introduced and examined for in-situ application. An imaging system was built up using a digital camera and was installed on the study sites in Incheon and Seoul separately. Visual range was also monitored by using a dual technology visibility sensor in Incheon and transmissometer in Seoul simultaneously. The Sobel mask filter was applied to detect the edge lines of objects by extracting the high frequency from the digital image. The root mean square (RMS) index of variation among the pixels in the image was substantially correlated with the visual ranges in Incheon and Seoul with correlations of R²=0.88 and R²=0.71, respectively. The regression line equations between the visual range and the RMS index in Incheon and Seoul were VR=2.36e 0.46×(RMS) and VR=3.18e0. 15×(RMS), respectively. It was also confirmed that the fine particles (PM 2.5 ) have more impacts to the impairment of visibility than coarse particles.

Secure Diagnostics And Forensics With Network Provenance

Distributed systems are behind many important services that we use every day, such as online banking, social media, and video conferencing. However, in a large-scale distributed system, many things can go wrong: routers can be misconfigured, programs can be buggy, and computers can be compromised by an attacker. To investigate these problems, system administrators need to play the role of ’part-time detectives’. Their tasks would be much easier if there were a way for them to ask the system to explain certain events, such as ’Why was this particular route chosen? ’. My work leverages data provenance a concept from the database community to enable distributed systems to offer such explanations. At a high level, provenance tracks causality between network states and events, and produces a detailed, structured explanation of any event of interest. Such information can be a helpful starting point when investigating a variety of problems, ranging from benign misconfigurations to malicious attacks. In this talk, I will present one technique in detail that can accurately pinpoint the root causes of problems by comparing the provenance of ’correct’ and ’incorrect’ events. I will then give an overview of my other work on network provenance, including an extension of provenance to repair network programs, and an application of secure provenance to the Internet’s data
Identifying and alleviating pain associated with routine husbandry procedures performed on pre and post weaning dairy calves

This thesis includes two studies that assessed pain responses to husbandry procedures in order develop mitigation tools. The objective of the first trial was to identify method-related differences in behavioral pain responses in calves of two ages (6 week and 6 months) subjected to castration: surgical cut (CP; n=18), surgical cut and emasculator (CC; n=20), rubber banding (BAND; n=18), or control manipulation of the scrotum (CONT; n=20). Behavior was evaluated preand post-castration to record foot stamps, tail flicks, kicks, elimination, in addition to standing and lying post-castration. For 6 week calves, the probability of kicking and eliminations was greater for surgical castrates and all castrated animals, respectively. The probability of kicking was greatest for all 6 month castrates while BAND and CONT had greater probability of elimination. Both age groups increased standing post-castration. Lying decreased in 6 week calves but was unchanged for 6 month calves. Six week calves displayed more tail flicks and tended to display less foot stamps than 6 month calves. Six week calves showed a decrease in tail flicks and foot stamps in response to castration while 6 month calves showed an increase in both behaviors. CP and CC, but not BAND, resulted in less tail flicks than CONT post castration. The second trial compared the effects of preemptive analgesics administered to calves subjected to dehorning with local anesthesia. Six month Holstein steers were randomly assigned to receive one of the following treatments (n= 8/group): meloxicam (1 mg/kg PO), gabapentin (15mg/kg PO), meloxicam (1 mg/kg) and gabapentin (15 mg/kg) PO, flunixin (2.2 mg/kg IV), or a placebo. Drug, cortisol, ex-vivo prostaglandin, haptoglobin, and substance P concentrations, ocular thermography, algometry, and average daily gain were evaluated. Analgesic-treated calves had lower plasma SP concentrations and improved ADG compared with controls. Flunixin calves had reduced cortisol and ex-vivo prostaglandin concentrations for 24h compared to controls. Meloxicam treated calves showed an increase in MNT at two horn bud sites compared with the other treatments. Overall, the results provide validation of responses to noxious stimuli that can be used to develop pain alleviation for livestock.
Parallel Genetic Algorithm Based Thresholding for Image Segmentation

Threshold plays a vital role in classification of objects and background in a given scene and hence segmentation. Determination of optimal threshold is hard for images exhibiting overlapping histogram distributions. In this paper, we propose a novel strategy of determining the threshold from histogram distributions. A feature image is generated from the given image and the optimal threshold is determined using the histogram of the featured pixels. The featured pixels are generated by considering a fixed window around a pixel. The histogram distributions are discrete in nature and hence Genetic Algorithm (GA) and Parallel Genetic Algorithm (PGA) based clustering algorithms are proposed to determine the optimal thresholds for two and three class problems. The optimal thresholds, thus determined could segment the noisy image. The efficacy of the proposed scheme is compared with that of the Otsu’s approach. Results obtained by the proposed scheme was comparable to that Otsu’s and in some noisy cases our method could be better than the latter one. Satisfactory results could also be obtained even for histograms with overlapping class distributions.
On Solving Some Issues in Cloud Computing

In past few years, cloud computing has emerged as one of the fastest growing segment in IT industry. It delivers infrastructure, platform, and software as a service on demand basis. Cloud provides several data centers at different geographical locations for service reliability and availability. Users can deploy applications and subscribe services from any location at competitive cost. However, this system doesn’t support mechanism and policies for dynamically coordinating load distribution among different cloud-based data centers. Further, cloud providers are unable to predict geographical distribution of users availing this services. There exist many challenging issues but few of them such as load balancing, event matching, and real-time data analysis have been addressed in the thesis. First three contributions in this thesis are dedicated to load balancing using evolutionary techniques. In the first contribution, a genetic algorithm based load balancing (LBGA) has been proposed with real value coded GA with a new encoding mechanism. Similarly, a particle swarm optimization based load balancing (LBPSO) is suggested. Both the schemes are simulated in cloud analyst, and performance comparisons are made with the competitive schemes.Consequently, both the schemes are grouped together to form a hybrid load balancing algorithm (HLBA). HLBA based central load balancer balances the load among virtual machines in cloud data center. HLBA utilizes the benefits of both genetic algorithm and particle swarm optimization. Different measures such as average response time, data center request service time, virtual machine cost, and data transfer cost are considered to evaluate the performance of the proposed algorithm. Suggested approach achieves better load balancing in large scale cloud computing environment as compared to other competitive approaches. In another contribution, an event matching algorithm has been developed for content-based event dissemination in publish/subscribe system. Proposed modified rapid match (MRM) algorithm has been compared with existing heuristics in the cloud system. Finally, a framework for the sensor-cloud environment for patient monitoring has been suggested. A prototype model has been developed for the purpose to validate the framework. This integrated system helps in monitoring, analyzing, and delivering real-time information on the fly.

Assessing the acoustic similarity of different pianos using an instrument-in-noise test

Speech-in-noise tests are a way to evaluate the perception of one or more aspects of phonetic elements. When varying the amount of noise, i.e., the signal-to-noise ratio (SNR), the target condition at which correct answers are given 50% of the times is of special interest. The obtained SNR is called speech reception threshold (SRT). In order to quantify how close two (non-speech) sounds are in terms of their acoustic properties, we hypothesise that a similar procedure can be followed. If we let subjects distinguish two sounds presented together with a background noise, and measure the SNR at which the two can no longer be distinguished, we expect a strong correlation between SNR and similarity: high similarity needs only little noise (high SNR) to make the sounds indistinguishable, whereas in a decreasing similarity an increasing amount of noise is needed (lower SNR). For a given pair of sounds, we can establish thus similarity by measuring the SNR at which they become indistinguishable. In this paper we present an example of such a method, applied to recorded Viennese piano sounds. As in every speech-in-noise test, the noise to be used has to be carefully chosen. We chose a set of noises that are shaped according to the spectro-temporal properties of each note and instrument. Such a set was generated in a similar way as the so-called ICRA noises in speech, but being adapted to provide a more suitable “piano weighting”. Results for similarity scores for one piano note (C#5) and 7 test pianos are presented and discussed.
Outcomes geplanter außerklinischer und klinischer Low-Risk Geburten in Niedersachsen

Zusammenfassung Einleitung Die Sicherheit der außerklinischen Geburt wird international unterschiedlich bewertet. In Deutschland können Frauen mit niedrigem Risiko ihren Geburtsort frei wählen. Landesspezifische Untersuchungen sind bisher selten, jedoch nötig, da die Gesundheitssysteme sehr variieren und eine Vergleichbarkeit der Studien erschweren. Methoden Klinische und geplante außerklinische Geburten wurden 2005 in Niedersachsen prospektiv mit dem gleichen Dokumentationsinstrument erhoben. Frauen mit Einlingsschwangerschaft in Schädellage mit avisierter vaginaler Geburt ab 34+0 Schwangerschaftswochen post menstruationem wurden eingeschlossen. Von 4 424 Geburtsverläufen wurden anhand von Risikofaktoren 1 273 Geburtsverläufe ausgewählt. Außerklinische und klinische Geburten wurden mittels Odds Ratio, Chi-Quadrat-Test nach Pearson sowie dem Mann-Whitney-Test verglichen. Ergebnisse Außerklinisch gebaren 152 (36,6%) Erst- und 263 (63,4%) Mehrgebärende, in der Klinik 439 (51,2%) Erst- und 419 (48,8%) Mehrgebärende. Die intrapartale Verlegungsrate vom außerklinischen Setting in die Klinik lag bei 10,1%. Außerklinisch Gebärende waren älter und hatten einen höheren Bildungsstand. Bei den Klinikgeburten hatten Frauen häufiger einen Migrationshintergrund. Außerklinisch Gebärende nahmen häufiger eine Hebammenbetreuung vor und während des Gebärens in Anspruch. Außerklinisch wurde seltener eingeleitet und interveniert. In der Klinik wurden häufiger die Herztöne des Kindes mittels CTG, außerklinisch vor allem intermittierend überwacht. Die Geburtsdauer war bei außerklinisch gebärenden Frauen signifikant länger im Vergleich zu Frauen, die in der Klinik geboren haben (Median: EG: 9,01 h vs. 7,38 h; MG: 4,53 h vs. 4,25 h). Außerklinisch erlebten Erstgebärende (94,7%) häufiger eine Spontangeburt als in der Klinik (73,6%). Bei allen erfassten kindlichen Outcomes, mütterlichem Blutverlust und schweren Dammverletzungen zeigte sich kein Unterschied. Ein intakter Damm und Plazentalösungsstörungen waren in der Klinik seltener. Diskussion Bei guter Risikobewertung und Verlegungsorganisation bietet eine außerklinische Geburt ein angemessenes Sicherheitsniveau. Die Vorteile der außerklinischen Geburt wie persönliche Betreuung und weniger Interventionen sollten in Klinikkreißsälen integriert werden und können zu einer Verbesserung der Versorgung und Steigerung der Spontangeburtenrate beitragen.
