Joint Measurement and Trajectory Recovery in Visible Light Communication

The growing preponderance of light emitting diodes (LEDs) for lighting has motivated research into their dual use for visible light communication (VLC) and navigation. VLC extracts a bit sequence from a series of photodetector scans. Among this data is an LED ID that ensures the reliable data association in navigation and data communication. Recovering the LED data and ID requires the accurate prediction of each LED's projected position on the photodetector array to extract efficiently and reliably the LED ON-OFF status in each photodetector scan. Estimating the LED projected position is challenging because: 1) clutter and noise corrupt the measurements; 2) the LED status will be OFF in some scans; and 3) the predicted projection location sequence depends on the estimated rover state trajectory, which is uncertain and time varying. This paper presents a method to determine the q-most probable data and the LED position sequences simultaneously for a time window of data, using Bayesian multiple hypothesis tracking techniques by maximizing the posterior probabilities. This paper focuses on the VLC data and the LED position sequence extraction, which includes rover state estimation. Implementation of the multiple hypothesis tracking algorithm is illustrated by postprocessed experimental results.
Recommending Relevant Open Source Projects on GitHub using a Collaborative-Filtering Technique

The GitHub website represents nowadays an essential tool for developers from around the world; it is considered as a social network for them in which they can share their open source projects with others in a form of repositories. This paper presents and discusses the design and the implementation of a new recommender system for GitHub repositories based on a collaborative-filtering approach, which can be useful in many ways in the process of searching for the right solutions to build projects. The GitHub website is becoming very popular these days, a lot of projects are shared by millions of developers, building this recommender system can reduce searching time and make search results more and more relevant. The authors evaluate their system by conducting a set of experiments on a real data set using different well-known metrics and the k-fold cross validation method. Results obtained from these experiments are very promising, the authors found that their recommender system can reaches better precision and recall accuracy.
FATIGUE LIFE OF HIGH STRENGTH STEEL FOR COLD FORMING

The article presents the results of fatigue tests carried out on STRENX-type high-strength cold forming steel. For high-cycle fatigue tests carried out using low cycle loading frequencies of around 30 Hz, a ROTOFLEX machine was used. For ultra high-cycle tests, a KAUP-ZU testing machine was employed, which enables fatigue tests to be performed with symetric specimen loading (R = -1) and at a frequency of f ≈ 20 kHz. The relationships σ a = f(N) were determined experimentally in the high and ultra high-cycle region for STRENX high-strength steel. To determine the fatigue crack initiation mechanism, the fractographic analysis of fatigue fractures was made.
An epidemiological study of the incidence of salmonellas in pigs

SUMMARY The incidence of salmonellas in pigs was studied in five farms and a bacon factory. Persistence and spread of salmonella excretion in pigs in a breeding establishment is described. Salmonella excretor boars and sows were responsible for the spread and perpetuation of infection in the farm. The possibility of spreading salmonella infection between farms through the distribution of excretor pigs was studied. Infection persisted and was related to the initial state of excretion of the pigs while at the farm of origin. The importance of feeding stuffs as a source of salmonella infection in pigs is discussed. Specially prepared heat treated pellets fed to the pigs prevented the introduction of salmonellas.
Ultrasound image fusion - clinical implementation and potential benefits for monitoring of renal transplants.

PURPOSE To evaluate the feasibility of US image fusion in the clinical routine and to discuss potential benefits for follow-up after renal transplantation. MATERIALS AND METHODS 15 patients with a renal transplant were prospectively included in the study. For all of them, a previously performed CT- or MRI-scan covering the renal transplant was available. Each patient was investigated using ultrasound image fusion. Time needed for sucessful implementation of image fusion was registered. Subsequently, quality of image fusion was assessed by two experienced radiologists (10 and 5 years of experience) in consensus using a subjective 5 point rank scale (1 = best). RESULTS Image fusion was successfully performed in all patients. Time needed for setup of image fusion varied from 45-120 sec (85 ± 5 sec). The score for quality of US image fusion was 1.9 ± 0.7. CONCLUSION Assessment of renal transplants using US image fusion is feasible and provides several potential benefits for the follow-up of renal transplants.
A neuronal inhibitory domain in the N-terminal half of agrin.

Agrin is required for appropriate pre- and postsynaptic differentiation of neuromuscular junctions. While agrin's ability to orchestrate postsynaptic differentiation is well documented, more recent experiments have suggested that agrin is also a "stop signal" for the presynaptic neuron, and that agrin has actions on neurons in the CNS. To elucidate the neuronal activities of agrin and to define the receptor(s) responsible for these functions, we have examined adhesions of neurons and their neurite-outgrowth responses to purified agrin in vitro. We find that both full-length agrin and the C-terminal 95 kDa of agrin (agrin c95), which is sufficient to induce postsynaptic differentiation, are adhesive for chick ciliary ganglion (CG) and forebrain neurons. Consistent with previous findings, our results show that N-CAM binds to full-length agrin, and suggest that alpha-dystroglycan is a neuronal receptor for agrin c95. In neurite outgrowth assays, full-length agrin inhibited both laminin- and N-cadherin-induced neurite growth from CG neurons. The N-terminal 150 kDa fragment of agrin, but not agrin c95, inhibited neurite outgrowth, indicating that domains in the N-terminal portion of agrin are sufficient for this function. Adhesion assays using protein-coated beads and agrin-expressing cells revealed differential interactions of agrin with members of the immunoglobulin superfamily of cell adhesion molecules. However, none of these, including N-CAM, appeared to be critical for neuronal adhesion. In summary, our results suggest that the N-terminal half of agrin is involved in agrin's ability to inhibit neurite outgrowth. Our results further suggest that neither alpha-dystroglycan nor N-CAM, two known binding proteins for agrin, mediate this effect.
THE PHENOMENON OF THE ACUTE PHASE RESPONSE *

Avery never discussed the C-reactive protein without turning the conversation to what he was wont to call “the chemistry of the host. ” Although he never spelled out what he meant by that expression, he clearly had in mind all the unidentified body substances and mechanisms of a nonimmunological nature, both protective and destructive, that come into play in the course of infectious processes. + Rene J.

Recent Attempts at Immunotherapy

I F EEL highly privileged to be given this opportunity of the Lister Lecture to talk about recent therapeutic successes deriving from immunology. Immunotherapy is a term which has become popular recently in relation to measures against leukaemia and other neoplastic cellular invasions of the body but I use this term to include also the whole range of foreign parasitic invaders of the body. The term could apply, of course, to the early and highly successful use of immunoglobulins in specific bacterial infections: serotherapy. In recent years, however, immunologists have extended their knowledge of cell-mediated processes, which depend upon the tissue responses of delayed-type hypersensitivity and a population of lymphocytes under the primary control of the thymus gland. The same thymus-dependent mechanisms which are of first importance in rejection of a solid tissue (homograft) or tumour graft, are of major importance also in chronic bacterial diseases, such as tuberculosis or brucellosis and also many diseases due to viruses or fungi. These cell-mediated mechanisms are obviously the ones which modern immunotherapy would like to harness. Indeed, in current concepts of tumour immunity, antibody often appears as a thorough nuisance since it may involve tumour-enhancing properties. After a disastrous start in 1890 when Robert Koch used tuberculin in an attempt to cure tuberculosis, immunotherapy struck real popularity with Sir Almroth Wright's attempts to 'mobilize the immunological garrisons', during the first decade of the present century. In cases of local infection, the types of organism were determined, cultured and killed to yield auto-vaccines. These were injected into the patient, who was followed by repeated estimations of
Circannual reproductive rhythm in the European hamster (Cricetus cricetus): Demonstration of the existence of an annual phase of sensitivity to short photoperiod

Abstract: In the European hamster (Cricetus cricetus) short photoperiod (SP) is responsible for the transition between the breeding and the resting season and data obtained previously suggest that a circannual “clock” drives the annual rhythm of reproduction. This hypothesis implies the existence of a SP‐sensitive phase of the circannual system that occurs independently of the photoperiodic regime perceived by the animals after their arousal from hibernation at the end of March. In control animals kept outside, testicular atrophy occurs in August. When the animals were transferred from outdoors to controlled SP conditions (LD 10:14 and ambient temperature Ta = 18 ± 2°C), immediately (Group II) or 2, 4, 6 wk after capture (Groups IV, V, VI, respectively), sexual arrest occurs at the same time between mid‐June and mid‐July. In the other groups, transfer from outdoors to SP either after 6, 8, 10, 12 or 14 wk (Groups VI, VII, IX, X, XI, respectively) after capture, is followed directly within 4 wk by the gonadal atrophy. When SP was applied from the beginning of August (Group XII) gonadal atrophy was observed after only 2 wk. In this last group, however, the rapid involution is the consequence of the already initiated decline in sexual activity induced by the short daylengths from July. When comparing the effect of SP in two different ambient temperatures (Ta: 18 ± 2°C vs 7 ± 2°C), immediately (Groups II vs III), 8 (Groups VII vs VIII) or 16 (Groups XII vs XIII) wk after capture, it appears that low temperature does not affect the physiological process described above. In the European hamster, after the gonadal regrowth at the end of hibernation, the animals do not need to experience increasing long days to react against SP. Gonadal inhibition is induced when, following our hypothesis, SP coincides with an endogenous period of sensitivity that extends from mid‐May to at least July‐August. The present findings complement and extend earlier evidence to support the existence of an endogenous circannual control of seasonal reproduction in the European hamster.
Functional analysis of the nuclear LIM domain interactor NLI

LIM homeodomain and LIM-only (LMO) transcription factors contain two tandemly arranged Zn2+-binding LIM domains capable of mediating protein-protein interactions. These factors have restricted patterns of expression, are found in invertebrates as well as vertebrates, and are required for cell type specification in a variety of developing tissues. A recently identified, widely expressed protein, NLI, binds with high affinity to the LIM domains of LIM homeodomain and LMO proteins in vitro and in vivo. In this study, a 38-amino-acid fragment of NLI was found to be sufficient for the association of NLI with nuclear LIM domains. In addition, NLI was shown to form high affinity homodimers through the amino-terminal 200 amino acids, but dimerization of NLI was not required for association with the LIM homeodomain protein Lmxl. Chemical cross-linking analysis revealed higher-order complexes containing multiple NLI molecules bound to Lmx1, indicating that dimerization of NLI does not interfere with LIM domain interactions. Additionally, NLI formed complexes with Lmx1 on the rat insulin I promoter and inhibited the LIM domain-dependent synergistic transcriptional activation by Lmx1 and the basic helix-loop-helix protein E47 from the rat insulin I minienhancer. These studies indicate that NLI contains at least two functionally independent domains and may serve as a negative regulator of synergistic transcriptional responses which require direct interaction via LIM domains. Thus, NLI may regulate the transcriptional activity of LIM homeodomain proteins by determining specific partner interactions.

Seborrheic keratosis in the Korean males: causative role of sunlight

Background/Purpose: Seborrheic keratoses (SKs) are common epidermal tumors in the white population over 40 years. The etiology of SKs is not well known; however, exposure to sunlight was suggested to play a role in the development of them. To our knowledge, no well‐designed study has been undertaken in order to investigate the clinical characteristics of SKs in a brown‐skinned Korean population. The aim of this study was to assess the prevalence and clinical features of SKs in the Korean males and to investigate the possible relationship of SKs with sun exposure and possible risk factors of developing SKs.
The Hebephiliac: Pedophile or Teleiophiliac?

The current study aims to fill the gap on hebephile sex offenders by comparing them to a group of pedophile offenders as well as a group of teleiophile offenders. The focus of the study is to examine the victims’ and offenders’ characteristics, the crime characteristics, and the modus operandi used by a sample of 111 male sex assaults currently serving a sentence for sexual crimes in Korea. Looking at all the comparisons conducted, it seems that the hebephiliac is not more similar to the pedophile nor the teleiophiliac. He is in fact a mix of both. Aside from certain characteristics that make hebephiliacs different from the other two subtypes of sex offenders (e.g., sadism, travelling longer than 2 km to commit the crime, history of bipolar disorder), they mainly share characteristics of both groups. The current study uncovers very important differences that could prove useful for the management of these cases by the actors of the criminal justice system.
A novel emergency management platform for smart public safety

This paper proposes an efficient architecture of a smart public safety platform that involves public professional operators as well as citizens. The proposed system is compliant with the emerging paradigm of a smart city. Its main features are that of monitoring, forecasting and managing emergency situations, arising from environmental disasters or crimes. The proposed platform performs a smart and functional integration of heterogeneous components as a smart data gathering and analysis system, a novel professional communication system, wireless sensor networks and social networks. Each element acts not only as an information collector but has autonomous capabilities to cooperate with the others in order to increase the system efficiency and to reduce the need of human interactions. Finally, the paper highlights some open research issues that represent critical aspects and require additional investigations in order to further improve the performance of the proposed platform.

Joint optimisation algorithm of cooperative spectrum sensing with cooperative overhead and sub‐band transmission power for wideband cognitive radio network

Cognitive radio (CR) allows a secondary user (SU) to utilise the spectrum allocated to the primary user (PU) on the premise of detecting the absence of PU by spectrum sensing. The SU often adopts cooperative spectrum sensing to cope with the hidden terminal problem if the PU is shadowed or in serious multi‐path fading; however, the cooperative overhead may decrease the throughput of the SU. In this paper, we consider a wideband CR network that can reuse multiple idle sub‐bands after cooperative spectrum sensing and then analyse the total throughput of the SU over all the sub‐bands. A multi‐variable nonconvex optimisation problem of cooperative spectrum sensing with cooperative overhead and sub‐band transmission power is proposed, which maximises the total throughput of the SU subject to the constraints of the false‐alarm probability, the detection probability, the cooperative overhead and the maximal total power of the SU. For obtaining the optimal solution, we divide the optimisation problem into two sub‐optimisation problems: one for optimising the cooperative spectrum sensing including the sensing time and the number of SUs and the other one for optimising the sub‐band transmission power. We have proven the convex optimisation of the two sub‐optimisation problems and proposed a joint optimisation algorithm of the sensing time, the number of SUs and the sub‐band transmission power. The simulation results show that the proposed joint optimisation algorithm can achieve the largest throughput with the false‐alarm probability and the detection probability within their limits.

Untangling the concept of coercive control: Theorizing domestic violent crime

The article assesses three approaches to domestic violence: two that use the concept of ‘coercive control’ and one that uses ‘domestic violent crime’. These are: Stark’s concept of coercive control; Johnson’s distinction between situational couple violence and intimate terrorism, in which coercive control is confined to the latter; and that of domestic violent crime, in which all physical violence is conceptualized as coercive and controlling. The article assesses these three approaches on seven issues. It offers original analysis of data from the Crime Survey for England and Wales concerning variations in repetition and seriousness in domestic violent crime. It links escalation in domestic violent crime to variations in the economic resources of the victim. It concludes that the concept of domestic violent crime is preferable to that of coercive control when seeking to explain variations in domestic violence.
Motion analysis and removal in intensity variation based OCT angiography.

In this work, we investigated how bulk motion degraded the quality of optical coherence tomography (OCT) angiography that was obtained through calculating interframe signal variation, i.e., interframe signal variation based optical coherence angiography (isvOCA). We demonstrated theoretically and experimentally that the spatial average of isvOCA signal had an explicit functional dependency on bulk motion. Our result suggested that the bulk motion could lead to an increased background in angiography image. Based on our motion analysis, we proposed to reduce image artifact induced by transient bulk motion in isvOCA through adaptive thresholding. The motion artifact reduced angiography was demonstrated in a 1. 3μm spectral domain OCT system. We implemented signal processing using graphic processing unit for real-time imaging and conducted in vivo microvasculature imaging on human skin. Our results clearly showed that the adaptive thresholding method was highly effective in the motion artifact removal for OCT angiography.
Dysfunctional parenting as a risk factor to lifetime depression in a sample of employed Japanese adults: evidence for the ‘affectionless control’ hypothesis

Background. Although many case–control studies have replicated an association between dysfunctional parenting and a lifetime diagnosis of depression, few epidemiological studies have explored the association. In addition, little is known about the association in non-western countries. Methods. Using logistic regression analyses, additive and interactive contributions of parental child-rearing behaviours, as measured by the Parental Bonding Instrument (PBI), toward the risk for having a lifetime diagnosis of major depressive disorder were explored in 418 employed Japanese adults. The diagnosis was provided by using the Inventory to Diagnose Depression, lifetime version. The analyses were conducted for male and female subjects separately. Results. Parental care rather than parental protection was primary in predicting lifetime depression in both male and female subjects. An interactive combination of low care and high protection (‘affectionless control’) was a significant risk factor for lifetime depression in male respondents' reporting child-rearing behaviours of both parents and female respondents' reporting paternal child-rearing behaviours. Model improvements when entering the PBI scores were larger in male subjects than in female subjects. Conclusions. The results suggested that a combination of low care and over-protection increases a risk to lifetime depression even in a non-clinical sample; that an association between dysfunctional parenting (particularly low care) and the development of depression is independent of culture; and that Japanese boys are more sensitive than Japanese girls to dysfunctional parenting as regards the development of depression.
THE RESPONSE OF TALL FESCUE AND ITS FUNGAL ENDOPHYTE TO CLIMATE CHANGE

OF THESIS THE RESPONSE OF TALL FESCUE AND ITS FUNGAL ENDOPHYTE TO CLIMATE CHANGE Tall fescue is the most common cool-season grass in the eastern USA, with broad economic and ecological importance to the region. Tall fescue is known to associate with a fungal endophyte, Neotyphodium coenophialum, whose presence can decrease biotic and abiotic stress experienced by the plant. This thesis evaluates the response of tall fescue and the fungal endophyte symbiosis to predicted climate change. I participated in two multi-factor climate change projects where I investigated the response of tall fescue tissue chemistry and growth to various climate change factors. Endophyte-infected (E+) tall fescue had decreased alkaloid production under elevated CO2 but increased alkaloid production under elevated temperatures. Significant differences between E+ and E(endophyte-free) tall fescue tissue chemistry were also found, suggesting the endophyte interacts with the plant response to abiotic stress. Although several studies have reported benefits of endophyte infection for tall fescue growing under drought stress, my research found no differences between E+ and Etotal growth and surprisingly showed increased mortality of E+ individuals under elevated temperature. Taken together, my research indicates that this grass-fungal relationship will respond to climate change, and may produce dramatic and unforeseen results that question the widely believed mutualistic nature of the symbiosis.
