Local convergence of random graph colorings

Let $G=G(n,m)$ be a random graph whose average degree $d=2m/n$ is below the $k$-colorability threshold. If we sample a $k$-coloring $\sigma$ of $G$ uniformly at random, what can we say about the correlations between the colors assigned to vertices that are far apart? According to a prediction from statistical physics, for average degrees below the so-called {\em condensation threshold} $d_c(k)$, the colors assigned to far away vertices are asymptotically independent [Krzakala et al.: Proc. National Academy of Sciences 2007]. We prove this conjecture for $k$ exceeding a certain constant $k_0$. More generally, we investigate the joint distribution of the $k$-colorings that $\sigma$ induces locally on the bounded-depth neighborhoods of any fixed number of vertices. In addition, we point out an implication on the reconstruction problem

Adaptive Filtering for Heart Rate Signals

This work focused on the effects of suppressing the motion artifact of wrist photoplethysmographic heart rate signals. Monitoring of the heart can offer important insight with regard to health and wellness. The objective of the experiment conducted here was to recover the distorted signal resulting from body movement while measuring the heart rate signal non-invasively from the wrist. The class of filters, known as adaptive filters, that can extract meaningful information from the distorted signal, used predetermined initial conditions to equalize the signal distortion due to motion. These filters do not require prior knowledge about the system. Adaptive filters of LMS-type and RLS-type were used in this study to recover the distorted heart rate signal. This study also presented a comparison on short-range wireless technologies, such as Bluetooth and ANT+, that can be used for data transmission of the heart rate signal

Language Debates and the Changing Context of Educational Policy in Morocco

Language is a critical basis of local identity and a vital tool for global communication. In multilingual Morocco, the issue of language instruction has been highly politicized, a factor that has contributed to poor educational practice. This article aims at providing a brief description of Morocco’s linguistic landscape together with the language policies first established in Morocco by the French colonizer. It goes on to further assess the evolution of language education policy and makes recommendations for strengthening Morocco’s multilingualism

About 10 percent of Americans identify as polyamorous, defined as having multiple love affairs within a single relationship. Those relationships are as diverse as they are complicated with some ranging from having multiple people within a relationship to a couple having outside individual relationships. Within the gay world, polyamory and open relationships has become a norm, and within the gay fetish scene it’s almost a requirement. https://drive.google.com/open?id=0B_MnWyJVYJneYVAzXzcxU2U3bFE But polyamory has its own set of complications legally. Because in America we have a system where only one person can receive benefits (be it through marriage or blood), there are complications if, say, a three-person relationship loses a partner in death. What then happens to the two partners? Is there a system in place? My film follows a group of nine men within the fetish scene who all consider each other family — stronger than a bond of blood, they grew their family through their fetish. They are self-identified pups, and they consider their group to be a pack. Within that pack there is structure and hierarchy, just as you’d find in any family. And just like in any family you’d also see their bonds are built through kinship, tradition and passing down values. But there is nothing in place that legally recognizes their family. I follow the leader of the pack, who was deeply affected by a passing of one of his pups, and realized that if something were to happen to him, none of his pack would be protected

Effects of regular aerobic exercise on cardiorespiratory fitness and levels of fibrinogen, fibrin D-dimer and uric acid in healthy and inactive middle aged men

Background and aims: The aim of this study was to investigate the effects of three months regular aerobic exercises on the levels of fibrinogen, fibrin D-dimer, uric acid, white blood cells count (WBC), red blood cell distribution width (RDW), body mass index (BMI) and cardiorespiratory fitness in middle aged healthy and inactive men. Methods: To implementation of this semi-experimental research, from employees in Ferdowsi university, 21 middle aged men with available method were selected and assigned into experimental (N=11, age: 44.7±4.3 y, height: 1.73±0.04 m, weight: 81.8±9.36 kg) and control (N=10, age: 41.2±8 y, height: 1.73±0.07 m, weight: 78.2±14.8 kg) groups. The experimental group performed an aerobic exercise protocol with the intensity of 75% to 85% of their maximum heart rate for three months (three days a week). Before and after trainings, aerobic power, body composition variables and fasting levels of blood variables were measured. Results: Data analysis showed a significant elevation of RDW, aerobic power and WBC and significant reduction of BMI and uric acid in experimental group (P<0.05), but no significant change was observed in the levels of fibrinogen and fibrin D-dimer. Conclusion: Considering reduction of some inflammatory atherosclerosis risk factors, aerobic exercise may be recommended for improvement of cardiovascular health in middle aged men

Genetic Characterization of Three Deer Species in Malaysia

In recent years, there has been much interest in the domestication and farming of deer in Malaysia for velvet, skin and meat production. Various deer species and subspecies have been imported into the country and this has resulted in the introduction of new germplasm and the risk of mixture of these, making it necessary to evaluate the genetic background of the various species before they are indiscriminately diluted or altered. This study was carried out to characterize three deer species i n Malaysia, namely rusa (Cervus timorensis), sambar (Cervus unicolor) and sika (Cervus nippon), by using the karyotyping, biochemical polymorphisms and randomly amplified polymorphic DNA (RAPD) techniques. The rusa herd at the Deer Breeding Unit of University Research Park, Universiti Putra Malaysia, the sambar herd at Pusat Permbiakan Ternakan Sabray, Kenungu, Sabah and the sika herd at Pusat Temakan Haiwan, Batu Arang were used as the research populations. Conventional, G-banded and C-banded karyotypes were generated for three male and three female deer of each species. The chromosome number was derived from 100 good metaphase spreads per animal. The morphology of the chromosomes was based on their relative lengths and position of the centromeres. Rusa, sambar and sika displayed a total of 60, 62 and 66 chromosomes in the majority of the cell spreads, respectively. The rusa deer had five pairs of metacentric/submetacentric and 24 pairs of acrocentric autosomes, and a pair of sex chromosomes. The X chromosome was characterised as the largest acrocentric chromosome, while the Y chromosome was a small acrocentric chromosome. The sambar deer had four pairs of metacentric/submetacentric and 26 pairs of acrocentric autosomes. The sex chromosomes were similar to that of rusa deer. In the sika deer there were two pairs of metacentric/submetacentric and 30 pairs of acrocentric autosomes. The pair of sex chromosomes was similar to those of the rusa and the sambar. The homologous chromosomes were paired with respect to their sizes, shapes and banding patterns generated from C-banding and G-banding. The nucleolar organizer regions (NORs) for the three deer species were 1 ocated on different chromosomes. The male r usa displayed NORs on the telomeric regions both homologues of Chromosomes 1 and 6, but the female displayed NORs on only one homologue of Chromosome 1, and both homologues of Chromosome 6. Male and female sambar deer both had three telomeric NORs located on the homologous pair of Chromosome 6 and a single homologue of Chromosome 7. Female and male sika deer displayed four NORs which were on the acrocentric Chromosomes 1 and 2. Cellulose acetate and starch g el electrophoresis were u sed to s tudy e nzymelprotein polymorphisms. Blood samples from 38 rusa, 9 sambar and 34 sika deer were analysed for 15 b iochemical m arkers, h owever, only six m arkers generated results. Lactate dehydrogenase (LDH), Albumin (ALB), Transferrin and X-protein were monomorphic. Haemoglobin (HB) was polymorphic with three phenotypes for the three species, which could b e attributed to two c odominant alleles, H B~ and HB*. The frequency of H B w~as highest in the rusa population, 0.553, while HBB was predominant in sambar, 0.61 1, and sika, 0.574. The rusa and sika populations showed significant (P<0.05) deviations from HWE for this locus. Glucose-6-phosphate dehydrogenase (GGPD), although polymorphic, was monomorphic within each species. Rusa and sambar showed the same phenotype, but this was different from that of the sika. The genetic distance between rusa and sambar based on the above biochemical markers was 0.001, between rusa and sika it was 0.144, and between sambar and sika it was 0.141. The animals used in the biochemical study were a Iso analyzed for RAPD markers using 10 arbitrary primers. The primers amplified a total of 164 makers, of which 59 were shared by a 11 three species. The overall percent polymorphism was 9 9.39%, with rusa showing 128 polymorphic markers (97.71%), sambar showing 66 (68.04%) and sika showing 118 (95.16%) polymorphic markers. The 62B-1 (800 bp) band was a c ornrnon monomorphic m arker for the three species. Sambar had five e xclusive monomorphic markers, while sika had one and rusa none. The genetic distance based on Dice and Jaccard similarity indices showed sambar and sika to be the most closely related, followed by rusa and sambar
