Published: January 2023

IntroductionObesity, sedentarism, and insulin resistance are strongly associated with increased deoxyribonucleic acid fragmentation index (DFI) of sperms, reduced total testosterone (TT), and low semen quality, which can be prevented by lifestyle modification. This study aimed to investigate the effect of 14-week moderate-intensity aerobic exercise on serum TT, semen parameters, and DFI in centrally obese men with hyperglycaemia.MethodsOverall, 40 men aged 26–39 years with waist circumference (WC) > 102 cm, body mass index (BMI) limited from 30 to 34.9 kg/m2, and fasting blood glucose (FBG) levels of 100–125 mg/dl were assigned to the study and control groups. The study group (<i>n</i> = 20) received supervised 14-week moderate-intensity aerobic exercise on a treadmill for 40 minutes, 3 times weekly, in addition to 1-hour home walking (on the alternative days of aerobic exercise), while the control group (<i>n</i> = 20) received general advice on increasing physical activity.ResultsIn the study group, exercise significantly improved BMI, WC, FBG, serum TT, sperm DFI, and semen parameters, including motility (progressive and static) and morphology (<i>p</i> < 0.05), while the volume and count of semen showed no significant difference. The control group presented no significant changes.ConclusionsThe deteriorating effect of central adiposity, hyperglycaemia, and sedentarism on semen quality and nuclear damage of sperms (assessed by DFI) is prevented or counteracted by increased exercise-induced TT production, resulting from decreased BMI, FBG, and WC.

Abstract. The Henry's law solubility (HS) and liquid-phase loss rate constants (kl) of the tropospheric trace gas constituents
peroxyacetic nitric anhydride (PAN; CH3C(O)O2NO2, commonly known as peroxyacetyl nitrate) and peroxypropionic nitric
anhydride (PPN; C2H5C(O)O2NO2, also known as peroxypropionyl nitrate) in deionized (DI) water and of PPN in n-octanol
were measured using a flow bubble apparatus at temperatures between 5.0 and 25.0 ∘C. For PAN in DI water, the observed values
for HS,aq are consistent with the literature, whereas the solubility of PPN in DI water is slightly lower than literature
values, ranging from HScp(PPN)aq = (1.49 ± 0.05) M atm−1 at 25.0 ∘C to
HScp(PPN)aq = (7.01 ± 0.25) M atm−1 at 5.0 ∘C (stated uncertainties are
at the 1σ level). The data are best described by
ln⁡(HScp(PAN)aq/[Matm-1]) = -(17.8±0.3) + (5620±85)/T and
ln⁡(HScp(PPN)aq/[Matm-1]) = -(19.5±1.7) + (5955±480)/T, where T is in
kelvin. For n-octanol, the PPN solubility ranges from
HScp(PPN)oct = (88±5)Matm-1 at 25.0 ∘C to
HScpoct = (204±16)Matm-1 at 5.0 ∘C and is best described by
ln⁡(HScp(PPN)oct/[Matm-1]) = -(6.92±0.75) + (3390±320)/T. n-Octanol–water
partition coefficients (KOW) for PPN were determined for the first time, ranging from 59 ± 4 at 25.0 ∘C to
29 ± 3 at 5.0 ∘C. Observed loss rate constants in DI water are consistent with recent literature and larger than the thermal
dissociation rates for both PAN and PPN, consistent with a hydrolysis mechanism, whereas kl values in n-octanol are
significantly smaller than gas-phase dissociation rate constants, likely owing to a “cage effect” in the organic liquid. The results imply that
uptake of either PAN or PPN on cloud water and organic aerosol is negligible but that uptake of PPN may constitute an
overlooked source of peroxy radicals in organic aerosol.

Published: January 2023

Abstract. Orographic gravity waves (i.e., mountain waves) can potentially lead to cross-isentropic fluxes of trace gases via the generation of
turbulence. During the DEEPWAVE (Deep Propagating Gravity Wave Experiment) campaign in July 2014, we performed tracer measurements of carbon monoxide
(CO) and nitrous oxide (N2O) above the Southern Alps during periods of gravity wave activity. The measurements were taken along two
stacked levels at 7.9 km in the troposphere and 10.9 km in the stratosphere. A detailed analysis of the observed wind components
shows that both flight legs were affected by vertically propagating gravity waves with momentum deposition and energy dissipation between the two
legs. Corresponding tracer measurements indicate turbulent mixing in the region of gravity wave occurrence. For the stratospheric data, we identified mixing leading to a change of the cross-isentropic tracer gradient of N2O from the upstream to the
downstream region of the Southern Alps. Based on the quasi-inert tracer N2O, we identified two distinct layers in the stratosphere with
different chemical composition on different isentropes as given by constant potential temperature Θ. The CO–N2O relationship
clearly indicates that irreversible mixing between these two layers occurred. Further, we found a significant change of the vertical profiles of
N2O with respect to Θ from the upstream to the downstream side above the Southern Alps just above the tropopause. A scale-dependent
gradient analysis reveals that this cross-isentropic gradient change of N2O is triggered in the region of gravity wave occurrence. The power spectra of the in situ measured vertical wind, Θ, and N2O indicate the occurrence of turbulence above the mountains
associated with the gravity waves in the stratosphere. The estimated eddy dissipation rate (EDR) based on the measured three-dimensional wind indicates a
weak intensity of turbulence in the stratosphere above the mountain ridge. The Θ–N2O relation downwind of the Alps modified by the
gravity wave activity provides clear evidence that trace gas fluxes, which were deduced from wavelet co-spectra of vertical wind and N2O, are
at least in part cross-isentropic. Our findings thus indicate that orographic waves led to turbulent mixing on both flight legs in the troposphere and in the stratosphere. Despite
only weak turbulence during the stratospheric leg, the cross-isentropic gradient and the related composition change on isentropic surfaces from
upstream to downstream of the mountain unambiguously conserves the effect of turbulent mixing by gravity wave activity on the trace gas distribution
prior to the measurements. This finally leads to irreversible trace gas fluxes across isentropes and thus has a persistent effect on the upper
troposphere and lower stratosphere (UTLS) trace gas composition.
Solar occultation measurement of mesospheric ozone by SAGE III/ISS: impact of variations along the line of sight caused by photochemistry
Authors: Natarajan Murali , Damadeo Robert , Flittner David 
Published: January 2023

Abstract. Twilight gradients in the concentration of atmospheric species
with short photochemical lifetimes influence the transmission data obtained
in a solar occultation instrument, such as the Stratospheric Aerosol and Gas Experiment III aboard the International Space Station (SAGE III/ISS). These photochemically induced changes result in nonlinear asymmetries in the species distribution near the tangent altitude along the line of sight
(LOS). The bias introduced by neglecting the effects of twilight variations
in the retrieval of mesospheric ozone is the focus of this study. Ozone (O3) in the mesosphere exhibits large variations near the terminator during sunrise
and sunset based on current understanding of the photochemistry of this
altitude region. The algorithm used in the SAGE III/ISS standard retrieval
procedure for mesospheric ozone does not include the effects of these
gradients. This study illustrates a method for implementing a correction
scheme to account for the twilight variations in mesospheric O3 and
gives an estimate of the bias in the standard retrieval. We use the results
from a diurnal photochemical model conducted at different altitudes to
develop a database of ratios of mesospheric O3 at different solar
zenith angles (SZA) around 90∘ to O3 at a SZA of
90∘ for both sunrise and sunset conditions. These ratios are used
to scale the O3 at levels above the tangent altitude for appropriate
SZA in the calculation of the optical depth along the LOS. In general, the
impact of the corrections due to twilight variations is to increase the
contribution of the overlying layers to the optical depth thereby reducing
the retrieved O3 concentration at the tangent altitude. We find that
at sunrise the retrieved mesospheric O3 including the diurnal
corrections is lower by more than 30 % compared to the archived O3.
We show the results obtained for different latitudes and seasons. In
addition, for nearly collocated sunrise and sunset scans, we note that these
corrections lead to better qualitative agreement in the sunrise to sunset
O3 ratio with the photochemical model prediction.
Adapting a deep convolutional RNN model with imbalanced regression loss for improved spatio-temporal forecasting of extreme wind speed events in the short to medium range

Published: January 2023

Abstract. The number of wind farms and amount of wind power production in Europe, both on- and offshore, have increased rapidly in the past years. To ensure grid
stability and on-time (re)scheduling of maintenance tasks and to mitigate fees in energy trading, accurate predictions of wind speed and wind power are
needed. Particularly, accurate predictions of extreme wind speed events are of high importance to wind farm operators as timely knowledge of these
can both prevent damages and offer economic preparedness. This work explores the possibility of adapting a deep convolutional recurrent neural
network (RNN)-based regression model to the spatio-temporal prediction of extreme wind speed events in the short to medium range
(12 h lead time in 1 h intervals) through the manipulation of the loss function. To this end, a multi-layered convolutional long
short-term memory (ConvLSTM) network is adapted with a variety of imbalanced regression loss functions that have been proposed in the literature:
inversely weighted, linearly weighted and squared error-relevance area (SERA) loss. Forecast performance is investigated for various intensity
thresholds of extreme events, and a comparison is made with the commonly used mean squared error (MSE) and mean absolute error (MAE) loss. The
results indicate the inverse weighting method to most effectively shift the forecast distribution towards the extreme tail, thereby increasing the
number of forecasted events in the extreme ranges, considerably boosting the hit rate and reducing the root-mean-squared error (RMSE) in those
ranges. The results also show, however, that such improvements are invariably accompanied by a pay-off in terms of increased overcasting and false
alarm ratio, which increase both with lead time and intensity threshold. The inverse weighting method most effectively balances this trade-off, with
the weighted MAE loss scoring slightly better than the weighted MSE loss. It is concluded that the inversely weighted loss provides an effective way
to adapt deep learning to the task of imbalanced spatio-temporal regression and its application to the forecasting of extreme wind speed events in
the short to medium range.

Published: January 2023

Abstract. The carbon (C) dynamics of northern peatlands are sensitive to hydrological changes owing to ecohydrological feedbacks. We quantified and evaluated the impact of water level variations in a beaver pond (BP) on the CO2 flux dynamics of an adjacent, raised
Sphagnum–shrub-dominated bog in southern Canada. We applied the CoupModel to the Mer Bleue bog, where the hydrological, energy and
CO2 fluxes have been measured continuously for over 20 years. The lateral flow of water from the bog to the BP was estimated by the
hydraulic gradient between the peatland and the BP's water level and the vertical profile of peat hydraulic conductivity. The model outputs were
compared with the measured hydrological components, CO2 flux and energy flux data (1998–2019). CoupModel was able to reproduce the measured data well. The simulation shows that variation in the BP water level (naturally occurring or due to management) influenced the bog net ecosystem exchange (NEE) of CO2. Over 1998–2004, the BP water level was 0.75 to 1.0 m lower than during 2017–2019. Simulated net CO2 uptake was 55 gCm-2yr-1 lower during 1998–2004 compared to 2017–2019 when there was no BP disturbance, which was similar to the differences in measured NEE between those periods. Peatland annual NEE was well correlated with water table depth (WTD) within the bog, and NEE also shows a linear relation with the water level at the BP, with a slope of −120 gCO2-Cm-2yr-1m-1. The
current modelling predicts that the bog may switch from CO2 sink to source when the BP water levels drop lower than ∼ 1.7 m below
the peat surface at the eddy covariance (EC) tower, located on the bog surface 250 m from the BP. This study highlights the importance of natural
and human disturbances to adjacent water bodies in regulating the net CO2 uptake function of northern peatlands.

CONSIDERATION OF THE PHYSICAL NONLINEARITY OF ORTHOTROPIC PLATE IN THE STATIC CALCULATION OF AN INFINITE REGULAR SYSTEM OF PLATES ON AN ELASTIC LAYER
Authors: KOZUNOVA O. , SIROSH K. 
Published: January 2023

An infinite regular system of orthotropic plates on an elastic layer rigidly connected to a non-deformable base is considered. Nonlinear calculation of an infinite regular system of plates on an isotropic basis is performed by the variational-difference method (VRM), which is characterized by the replacement of differential equations by finite-difference approximations. The numerical solution of the resulting system of equations is performed using an iterative algorithm.
When finding the variable stiffness of the plate on the elastic layer, the "stiffness – curvature" dependence on the Straw in the directions of the axes of inertia is used. According to the found cylindrical bending stiffness from the ratio of S.P. Timo-shenko, the torsion stiffness of the plate is determined for each iteration. The energy of deformation of the elastic base is replaced by the work of reactive pressures in the contact zone of the structure on the basis of the law of conservation of energy.
The analysis of the results of elastic and nonlinear calculations (3rd iteration) was carried out for the values of the orthotropic plate sediment and contact stresses in the zone of interaction of the plate with the elastic base.
Where There’s a Will, There’s a “Why?” Part 2: Implications of Value Determinism for the Objectivist Concepts of “Value,” “Sacrifice,” “Virtue,” “Obligation,” and “Responsibility”
Authors: Bissell Roger E. 
Published: January 2023

ABSTRACT
The author continues his challenge to the “official” Objectivist view of free will by addressing the implications of his value-determinism/conditional-volition model for various Objectivist moral concepts including value, sacrifice, virtue, obligation, and moral and legal responsibility and accountability. He argues that based on Rand’s definitions, the conventional understandings of sacrifice or betrayal of values, lapses in virtue, and breaches in morality need considerable reconceptualizing. The author gives special attention to Rand and Kant with regard to lying, use of force, and acts of generosity, finding not nearly as much difference between them as is commonly believed.
