Inorganic scintillators are important elements of a new type of cryogenic phonon scintillation detector (CPSD) being developed for single particle detection. These detectors, exhibiting superior energy resolution and the ability to identify the type of interaction in an event, are considered to be the next generation of instrumentation in the search for extremely rare events. This paper present...

Most isolates of Streptococcus pneumoniae are mixed populations of transparent (T) and opaque (O) colony phenotypes. Differences in the production of capsular polysaccharide (CPS) between O and T variants were accentuated by changes in the environmental concentration of oxygen. O variants demonstrated a 5.2- to 10.6-fold increase in amounts of CPS under anaerobic compared to atmospheric growth ...

Acid stress can affect the viability of probiotics, especially Bifidobacterium. This study aimed to improve the acid tolerance of Bifidobacterium longum BBMN68 using adaptive evolution. The stress response, and genomic differences of the parental strain and the variant strain were compared by acid stress. The highest acid-resistant mutant strain (BBMN68m) was isolated from more than 100 asexual...

OBJECTIVE To evaluate the relationship between peripapillary focal arteriolar narrowing and visual field defects. METHODS From our institutional practice, we identified 31 patients with glaucoma who had peripapillary focal arteriolar narrowing in only one eye and compared visual field data between the two eyes. Mean deviation (MD) and corrected pattern standard deviation (CPSD) were recorded ...

PURPOSE To introduce a new method, derived from the Glaucoma Staging System (GSS), for classifying glaucomatous visual field defects. PATIENTS AND METHODS Four sample groups composed respectively of 471 (sample #1), 128 (sample #2), 185 (sample #3), and 131 (sample #4) patients with either ocular hypertension or chronic glaucoma were considered. The GSS 2 uses both the MD and CPSD/CLV or PSD/...

In this paper we consider the hermitian extension of the cross-ΨB-energy operator that we will denote by ΨH . In addition, cross energy terms are formalized through multivariate signals representation. We investigate the connection between the interaction energy function of ΨH and the cross-power spectral density (CPSD) of two complex valued signals. In particular, this link permits to use this...

Aim: To perform a preliminary assessment of the relation between optic nerve circulatory parameters and glaucomatous visual field progression. Methods: This study included 29 eyes of 23 patients with open angle glaucoma that had typical glaucomatous nerve fibre bundle visual field defects and increased cup to disc ratios. Laser Doppler flowmetry (Oculix) was used to measure relative optic nerve...

This paper presents new spectrum sensing algorithms based on the cumulative power spectral density (CPSD). The proposed detectors examine the CPSD of the received signal to make a decision on the absence/presence of the primary user (PU) signal. Those detectors require the whiteness of the noise in the band of interest. The false alarm and detection probabilities are derived analytically and si...

PURPOSE To assess the effects of topical betaxolol and timolol on the visual field in Japanese open-angle glaucoma (OAG) patients. METHODS This study was a multicenter, 2-year, prospective, randomized and double-masked study. Tests using the Humphrey 30-2 perimeter program were conducted every 6 months and the data of 95 patients were analyzed using regression analysis. Estimated regression c...
