In this paper we obtained new automorphic analogue of Baer's theorem for the case when an arbitrary subgroup $A\leq Aut(G)$ includes a group of inner automorphisms $Inn(G)$ of agroup $G$ and the factor-group $A/Inn(G)$ is co-layer-finite.

Mean daily traffic (MDT) is the expected traffic volume at some site on a typical day, and it is usually estimated from short-count data by computing average daily traffic (ADT) and then correcting this ADT for the season or day of week of the count. Although considerable guidance exists on how to construct seasonal factor groups from automatic traffic recorder counts, less guidance is available on how to select the appropriate factors for correcting a particular short count or for estimating MDT when the appropriate factors are uncertain. A data-driven approach to assigning highway sites to factor groups using arbitrary samples of daily traffic counts, a method for designing traffic count samples to minimize the likelihood of assigning the site to the wrong factor group, and a Bayes estimator of MDT are described. A likelihood function describing the sample count is combined with prior estimates of the probabilities that a site belongs to each factor group to produce posterior classification probabilities. The site is then assigned to that factor group showing the highest posterior classification probability. The classification method is evaluated by using actual traffic data and appears to perform reliably with 14-day samples. A Bayes estimator of MDT is then developed, which is applicable even when it is unclear to which factor group a short-count site ought to be assigned. This estimator is evaluated by using actual data, and it also performs creditably with 14-day samples.

BACKGROUND Chronic Obstructive Pulmonary Disease (COPD) is the fourth leading cause of death and is characterized by a progressive loss of pulmonary function over time with intermittent episodes of exacerbations. Rapid and proactive interventions may reduce the burden of the condition for the patients. Telehealth solutions involving self-tracking of vital parameters such as pulmonary function, oxygen saturation, heart rate and temperature with synchronous communication of health data may become a powerful solution as they enable healthcare professionals to react with a pro-active and adequate response. We have taken this idea to the next level in the Epital Care Model (ECM) and organized a person-centered technology assisted ecosystem to provide health services to COPD patients. OBJECTIVE The objective is to reveal the nature of COPD by combining technology with a person-centered design aimed to benefit from interactions based on PRO data and to assess the needed kind of contacts to best treat exacerbations. We wanted to know: 1) What is the incidence of mild, moderate and severe exacerbations in a mixed population of COPD patients? 2) What is the course of the mild, moderate and severe exacerbations? And 3) How is the activity and pattern of contacts to health professionals related to the participants condition? METHODS Convenience sampling during the period November 2013 to December 2015. The participants’ sex, age, FEV1, pulse rate and oxygen saturation were registered at entry. During the study, we registered number of days, number of exacerbations, number of contact notes coded into care and treatment notes. Each participant was classified according to GOLD I-IV and risk factor group A-D. Participants reported their clinical status using a tablet by answering four questions and sending three semi-automated measurements. RESULTS Of the 87 participants, 11 were in risk factor group A, 24 in B, 13 in C and 39 in D. The number of observed days was 31801 days with 12470 measurements and 1397 care notes and 1704 treatment notes. A total of 254 exacerbations were treated and only 18 caused hospitalization. Those in risk factor group D have the highest number of hospitalizations (16), exacerbations (151), and contacts (1910) The initial contacts during the first month declined within three months to 1/3 for care contacts and 1/2 for treatment contacts and reached a plateau after four months. CONCLUSIONS The majority of COPD patients in risk factor group D can be managed virtually and only 13% of those with severe exacerbations required hospitalization. Contact to the healthcare professionals decreases markedly within the first months after enrollment. These results provide a new and detailed insight into the course of COPD. We propose a resilience index for virtual clinical management making it easier to compare results across settings.

Objective: The purpose of this study was to investigate the vascular changes induced by mucoperiosteal denudation of rat palate and to elucidate the effects of basic fibroblast growth factor (bFGF) administration on the palatal vascular network in wound healing. Methods: A total of 117 male Wistar rats were used for the study on their 20th postnatal day. The animals were divided into three groups: a scar formation group, a basic fibroblast growth factor group, and a control group. The scar formation and basic fibroblast growth factor groups had lateral mucoperiosteum excised from the palate. In the basic fibroblast growth factor group, a solution of basic fibroblast growth factor was injected into the operated area 1 week after excision. At 6, 8, and 10 weeks postoperatively, palatal vascular changes were investigated by immunohistochemical staining and corrosion cast techniques. Results: Throughout the experimental period, there were significantly fewer vessels in the scar formation group than in the control and basic fibroblast growth factor groups. In the basic fibroblast growth factor group, the elongation of new vessels and capillary proliferation proceeded, and after 10 weeks a highly organized vascular network was established. The scar formation group showed few Volkmann's canals that were shrunken or closed, whereas the basic fibroblast growth factor group evidenced Volkmann's canals with arterioles or venules, as seen in the control. Conclusions: The results suggested that injection of basic fibroblast growth factor into palatal wounds improves the vascular supply to the operated mucosa and underlying bone during and after palatal wound healing, which may contribute to tissue remodeling of the palate during growth.

Streptococcal cell membrane (SCM) antiserum injected mice show a significant thickening of glomerular basement membrane (GBM) and an increase in mesangial matrix within 4 to 24 hours of antiserum administration (1,2,3). This study was undertaken to evaluate the incorporation of 3H proline into glomerular cells and GBM under normal and anti-SCM induced conditions. Mice were administered, intraperitoneally, 0.1 ml of normal or anti-SCM serum followed by a 10 µC/g body weight injection of 3H proline. Details of the preparation of anti-SCM (Group A type 12 streptococcal pyogenes) and other sera and injection protocol have been described elsewhere (2). After 15 minutes of isotope injection a chase of cold proline was given and animal sacrificed at 20 minutes, 1,2,4,8,24 and 48 hours. One of the removed kidneys was processed for immunofluorescence, light and electron microscopic radioautographic studies; second kidney was used for GBM isolation and aminoacid analysis.

We have recently carried out a study of spermiogenic differentiation in two geographically isolated populations of Aphanius dispar (freshwater teleost), with a view to ascertaining variation at the ultrastructural level. The sampling areas were the Jebel Al Akhdar in the north (Group A) and the Dhofar region (Group B) in the south. Specimens from each group were collected, the testes removed, fixed in Karnovsky solution, post fixed in OsO, en bloc stained with uranyl acetate and then routinely processed to Agar 100 resin, semi and ultrathin sections were prepared for study.

Aim The purpose of this study was to develop and assess the reliability of a Hindi version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V). Reliability was assessed by comparing Hindi CAPE-V ratings with English CAPE-V ratings and by the Grade, Roughness, Breathiness, Asthenia and Strain (GRBAS) scale. Method Hindi sentences were created to match the phonemic load of the corresponding English CAPE-V sentences. The Hindi sentences were adapted for linguistic content. The original English and adapted Hindi CAPE-V and GRBAS were completed for 33 bilingual individuals with normal voice quality. Additionally, the Hindi CAPE-V and GRBAS were completed for 13 Hindi speakers with disordered voice quality. The agreement of CAPE-V ratings was assessed between language versions, GRBAS ratings, and two rater pairs (three raters in total). Pearson product–moment correlation was completed for all comparisons. Results A strong correlation ( r > .8, p < .01) was found between the Hindi CAPE-V scores and the English CAPE-V scores for most variables in normal voice participants. A weak correlation was found for the variable of strain ( r < .2, p = .400) in the normative group. A strong correlation ( r > .6, p < .01) was found between the overall severity/grade, roughness, and breathiness scores in the GRBAS scale and the CAPE-V scale in normal and disordered voice samples. Significant interrater reliability ( r > .75) was present in overall severity and breathiness. Conclusions The Hindi version of the CAPE-V demonstrates good interrater reliability and concurrent validity with the English CAPE-V and the GRBAS. The Hindi CAPE-V can be used for the auditory-perceptual voice assessment of Hindi speakers.

To test the relationship of adaptation and satiation as hypothesized by Jakobovits, satiation of meaning as a function of repeated readings for adaptation was measured in the performance of 14 male stutterers. The subjects as a group exhibited both satiation and adaptation, but the two phenomena did not occur simultaneously in a significant number of the members of the group. A reduction in meaningfulness, as measured by the semantic differential, was not shown to be a significant factor in the reduction of stuttering frequency for the individuals in the group. Satiation and adaptation were not established as the same phenomenon, although the two may still be related through another factor.
