Nano-imprint lithography of broad-band and wide-angle antireflective structures for high-power lasers.

We demonstrate efficient anti reflection coatings based on adiabatic index matching obtained via nano-imprint lithography. They exhibit high total transmission, achromaticity (99.5% < T < 99.

REDACS: Regional emergency-driven adaptive cluster sampling for effective COVID-19 management.

As COVID-19 is spreading, national agencies need to monitor and track several metrics. Since we do not have perfect testing programs on the hand, one needs to develop an advanced sampling strategies for prevalence study, control and management. Here we introduce REDACS: Regional emergency-driven adaptive cluster sampling for effective COVID-19 management and control and justify its usage for COVID-19.

Surveillance of SARS-CoV-2, rotavirus, norovirus genogroup II, and human adenovirus in wastewater as an epidemiological tool to anticipate outbreaks of COVID-19 and acute gastroenteritis in a city without a wastewater treatment plant in the Peruvian Highlands.

The coronavirus disease 2019 (COVID-19) pandemic has demonstrated that Wastewater Based Epidemiology is a fast and economical alternative for monitoring severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the community level in high-income countries. In the present study, wastewater from a city in the Peruvian Highlands, which lacks a wastewater treatment plant, was monitored for one year to assess the relationship between the concentration of SARS-CoV-2 and the reported cases of COVID-19 in the community. Additionally, we compared the relationship between rotavirus (RV), norovirus genogroup II (NoV GGII), and human adenovirus (HAdV) with the number of reported cases of acute gastroenteritis.

Beam-size effects on the measurement of sub-picosecond intrinsic laser induced damage threshold of dielectric oxide coatings.

Laser-induced damage experiments on and thin films were performed with 500 fs pulse duration at 1030 nm wavelength. Threshold fluences as a function of beam size have been determined for effective beam diameters ranging from 40 to 220 µm, in a single shot regime. The results suggest no beam-size effect related to material properties in the investigated range, but size effects related to the metrology.

Organic fertilization improves soil aggregation through increases in abundance of eubacteria and products of arbuscular mycorrhizal fungi.

An important goal of sustainable agriculture is to maintain soil quality. Soil aggregation, which can serve as a measure of soil quality, plays an important role in maintaining soil structure, fertility, and stability. The process of soil aggregation can be affected through impacts on biotic and abiotic factors.

On improved volatility modelling by fitting skewness in ARCH models.

We study ARCH/GARCH effects under possible deviation from normality. Since skewness is the principal cause for deviations from normality in many practical applications, e.g.

The different behaviors of glyphosate and AMPA in compost-amended soil.

The broad-spectrum herbicide glyphosate is one of the most widely used pesticides. Both glyphosate and its major metabolite, aminomethylphosphonic acid (AMPA), persist in waters; thus, their environmental fates are of interest. We investigated the influence of compost dose, sampling depth, moisture and saturated hydraulic conductivity (K) on the persistence of these substances.

Gender Differences of Arterial Stiffness and Arterial Age in Smokers.

The present study aimed to find gender differences for arterial stiffness and arterial aging in smokers. A total of 147 smokers (71 male and 76 female, matched for age) were explored using an Arteriograph in a cross-sectional survey. Pulse wave velocity (PWV), arterial age (AA), brachial and aortic augmentation index (AixBrach, AixAo), and blood pressure variables were assessed.

Fractal and stochastic geometry inference for breast cancer: a case study with random fractal models and Quermass-interaction process.

Fractals are models of natural processes with many applications in medicine. The recent studies in medicine show that fractals can be applied for cancer detection and the description of pathological architecture of tumors. This fact is not surprising, as due to the irregular structure, cancerous cells can be interpreted as fractals.

Stability of scaling regimes in d > or = 2 developed turbulence with weak anisotropy.

Fully developed turbulence with weak anisotropy is investigated by means of the renormalization group approach and double expansion regularization for dimensions d > or = 2. Some modification of the standard minimal subtraction scheme has been used to analyze the stability of the Kolmogorov scaling regime which is governed by the renormalization group fixed point. This fixed point is unstable at d=2; thus the infinitesimally weak anisotropy destroys the above scaling regime in two-dimensional space.

The Quadriplegia Index of Function (QIF): sensitivity and reliability demonstrated in a study of thirty quadriplegic patients.

The Quadriplegia Index of Function (QIF) was originally developed by the authors in 1980 because the popular Barthel Index was deemed too insensitive to document the small but significant functional gains made by quadriplegics (tetraplegics) during medical rehabilitation. The QIF has now been tested on a group of 30 complete quadriplegic patients at admission to and discharge from inpatient medical rehabilitation. Resultant scores were compared to those simultaneously obtained by the Barthel Index and the Kenny Self-Care Evaluation.

Retrospective evaluation of the isolation and identification of herpes simplex virus with Cultureset and human fibroblasts.

A total of 442 specimens from various anatomic sites was cultured for herpes simplex virus during the past 2 years. Most specimens were obtained from the respiratory tracts and cutaneous lesions of immunocompromised hosts (232 specimens) or the female genital tract (138 specimens). Two tubes containing human newborn foreskin fibroblasts and two Ortho Cultureset tubes containing Vero cells were inoculated with each specimen.
