Rapid assessment of main agronomic indicators in the grain of winter and spring forms of triticale using infrared spectroscopy

open access: yesТруды по прикладной ботанике, генетике и селекции
Background. Calibration models were developed for rapid assessment of crucial agronomic indicators in the grain of winter and spring triticale from the VIR collection using near-infrared spectroscopy (NIRS).

Investigation of NIR spectra pre-processing methods combined with multivariate regression for determination of moisture in powdered industrial egg

open access: yesActa Scientiarum: Technology, 2018
High productivity and meantime perishability of in natura eggs, make powdered egg attractive for patisseries and pasta industries. Water reduction in 65%, extends shelf life from 1 to 12 months, preventing also Salmonella.

Model- and calibration-independent test of cosmic acceleration

open access: yes, 2009
We present a calibration-independent test of the accelerated expansion of the universe using supernova type Ia data. The test is also model-independent in the sense that no assumptions about the content of the universe or about the parameterization of ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Rapid assessment of biochemical indicators of agronomic value in amaranth seed accessions from the VIR collection using NIR spectroscopy

open access: yesТруды по прикладной ботанике, генетике и селекции
Background. Amaranth (Amaranthus L.) is a relatively new crop for the Russian Federation, with huge potential for growth intensity, productivity, and other agronomic traits. Development of new amaranth cultivars is an important solution to the problem of

Empirical Absolute Calibration Model for Multiple Pseudo-Invariant Calibration Sites

open access: yesRemote Sensing, 2019
This work extends an empirical absolute calibration model initially developed for the Libya 4 Pseudo-Invariant Calibration Site (PICS) to five additional Saharan Desert PICS (Egypt 1, Libya 1, Niger 1, Niger 2, and Sudan 1), and demonstrates the efficacy

Ensemble learning of model hyperparameters and spatiotemporal data for calibration of low-cost PM2.5 sensors. [PDF]

open access: yes, 2019
he PM2.5 air quality index (AQI) measurements from government-built supersites are accurate but cannot provide a dense coverage of monitoring areas. Low-cost PM2.5 sensors can be used to deploy a fine-grained internet-of-things (IoT) as a complement to ...

Don't Fall for Tuning Parameters: Tuning-Free Variable Selection in High Dimensions With the TREX

open access: yes, 2015
Lasso is a seminal contribution to high-dimensional statistics, but it hinges on a tuning parameter that is difficult to calibrate in practice. A partial remedy for this problem is Square-Root Lasso, because it inherently calibrates to the noise variance.

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

open access: yesFEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Exploratory Analysis of ELP1 Expression in Whole Blood From Patients With Familial Dysautonomia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Familial dysautonomia (FD) is a hereditary neurodevelopmental disorder caused by aberrant splicing of the ELP1 gene, leading to a tissue‐specific reduction in ELP1 protein expression. Preclinical models indicate that increasing ELP1 levels can mitigate disease manifestations.
