Evaluation of the Adequacy of Design Specifications for Nonstructural Components in a Reticular Structure

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Nonstructural components (NSCs) installed in large‐span reticular structures were frequently severely damaged during earthquakes, even when the primary structure remained intact. Existing seismic design specifications for NSCs were predominantly developed for upright structures such as multi‐storey buildings and offer no guidance for reticular

Some Physical and Mechanical Properties of Polar Snow [PDF]

open access: yesJournal of Glaciology, 1963
AbstractSpecimens of polar snow from the South Pole, Antarctica, were tested to investigate air permeability K (cm.sec.−1), ultimate compressive strength σc (g.cm.−2) and dynamic Young’s modulus E (g.cm.−2) as a function of density. Anisotropy in a single layer of snow (snow between two summer crusts) was found in all three properties.

Comparative Assessment and Benchmarking of Metaheuristic Algorithms for Dynamic Photovoltaic Array Reconfiguration Under Diverse Shading Environments

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT The solar photovoltaic (PV) installations, which are essential for renewable energy systems, are vulnerable to partial shading, resulting in considerable power losses and operational inefficiencies. The dynamic reconfiguration of PV arrays has become an effective strategy to mitigate these effects by adaptively modifying the array topology to ...

Leveraging Machine Learning to Predict Food Waste Quantity: Focusing on Military Dining Facilities as Large‐Scale Food Service Operations

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Food waste reveals inefficiencies in resource use and contributes significantly to environmental pollution. In the United States, food waste accounts for the majority of total waste, with more than 50 million tons generated annually. In military units that operate large‐scale institutional food‐service facilities and generate significant food ...

Thermochronologic Constraints on the Extensional History of the Ibex Hills, Southeastern Black Mountains, Death Valley, California

open access: yesGeological Journal, EarlyView.
A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

MoT-PSA: a two-layer depth-averaged model for simulation of powder snow avalanches on 3-D terrain

open access: yesAnnals of Glaciology
For snow-avalanche hazard mapping, one needs efficient tools that nevertheless capture the essential physical processes. The code MoT-PSA (Method of Transport – Powder Snow Avalanche) described here is based on the two-layer depth-averaged formulation ...

Seasonal drivers of plant–soil–microbial community structure and functions in Western Himalayan grasslands, Pakistan

open access: yesGrassland Research, EarlyView.
Plant species richness was greater in summer in both alpine and subalpine grassland ecosystems. Soil moisture demonstrates significant positive correlations with soil organic carbon and total nitrogen across seasonal periods. Microbial α‐diversity peaks during summer but maintains functional stability across seasons.

Giving Up

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Philosophical accounts of long‐term goals focus predominantly on the rationality of perseverance, examining when agents should persist despite evidence of failure. Arguably, these accounts consider that giving up is devoid of value. Conversely, this article argues that giving up has a different epistemic function: generating information about ...

Macroscopic, Histological and Ultrastructural Features of the Tongue of the Anatolian Wild Boar (Sus scrofa libycus)

open access: yesMicroscopy Research and Technique, EarlyView.
Integrated macroscopic, histological, and ultrastructural analyses revealed five distinct lingual papillae types (filiform, fungiform, conical, foliate, and vallate) in the Anatolian wild boar (Sus scrofa libycus). Mechanical papillae showed marked structural specialization, while gustatory papillae exhibited region‐specific distribution of taste buds.

What Do Latest CMIP6 Global Climate Models Say About Future Arctic Sea Ice Coverage Changes?

open access: yesInternational Journal of Climatology, EarlyView.
Modelling of sea ice dynamics has significantly improved between CMIP5 and CMIP6, with nearly three times as many models capturing realistic annual variability in sea ice extent (SIE). What we previously thought was a non‐linear pattern of low SIE observations in 2007–2010 that would continue throughout time now appears to be non‐record‐setting lows in
