title: Cage Friction Measurements in High-Speed Bearings

description: This article presents a new test rig that was designed and developed to investigate the friction and lubrication condition of a ball and a cage of a deep groove ball bearing (DGBB) under high-speed conditions. In this test rig, the inner and outer raceway segments of a DGBB were precisely positioned using piezoelectric stages. This allowed independent control of the internal clearances between the raceways and the ball, enabling accurate representation of actual bearing geometry. The ball is mounted to a high-speed spindle motor, enabling angular rotational speeds of up to 24,000 RPM (DN<sup><sup>*</sup></sup> &gt; 1M). Frictional torque was measured using a six-axis load cell to quantify the friction between a ball and a cage pocket. A high-speed camera was used to capture the lubricant distribution within a transparent cage. The computer-aided design of the DGBB cage was used to manufacture the transparent cage. Experiments were conducted to investigate the effects of speed, ball-raceway clearance, oil flow rate, and lubricant viscosity on cage friction. The cage friction exhibited a dichotomic behavior, increasing in the oil-dominant regime at lower speeds and decreasing significantly in the air-dominant regime at higher speeds. The transition between different regimes was primarily influenced by raceway clearance and oil viscosity. The results from this investigation provide a detailed description into the ability of the cage pocket to sustain effective lubrication at elevated bearing speeds.

title: Boundary Closure in Radiative-Gravitational Systems

description: We identify and empirically validate a boundary-closure condition governing stable radiative–gravitational systems. The analysis is based on a dimensionless scalar invariant,

 

X = (L · G · M) / (g · R⁴ · c⁴ · T⁴),

 

constructed exclusively from independently measured boundary observables: luminosity, effective temperature, surface gravity, mass, and radius.

 

Using the Sun and two benchmark samples of detached eclipsing-binary components—where masses and radii are determined geometrically and temperatures and surface gravities spectroscopically—we find that the invariant converges to a single closed value set by fundamental constants,

 

X = 4πσ / c⁴.

 

When expressed in natural units (c = ħ = k_B = 1, σ = π² / 60), this becomes

 

X = π³ / 15 ≈ 2.067,

 

corresponding to the third-order Bose-Einstein integral.

The dispersion of X is 0.13% in the high-precision benchmark sample, consistent with observational uncertainties. Random reassignment (scrambling) of boundary observables between systems destroys the closure, demonstrating that the convergence reflects a physical boundary constraint rather than a definitional identity. The closure is interpreted as a consequence of radiative decoupling: the surface at which photon degrees of freedom detach from an optically thick interior and become defined as free-streaming radiation at the boundary.

title: Export strategies in companies exporting beans (Phaseolus lu-natus) from the agricultural sector, based on a systematic review with bibliometric analysis.

description: The present study is concerned with the challenges facing international trade in the agricultural sector, which are related to diversification, competitiveness and sustainability. In this regard, it is imperative for agricultural export companies dealing in lima beans to develop effective export strategies in order to strengthen their commercial performance. This research aims to determine the extent of the effectiveness of export strategies in export companies in the agricultural sector, based on a bibliometric analysis of scientific literature. The PRISMA 2020 methodology was applied, processing 8,578 records from Scopus, Dimensions and Web of Science, using Bibliometrix (RStudio) and VOSviewer tools for the analysis and visualisation of thematic networks, of which 44 articles between 1976 and 2024 met the inclusion criteria. The final corpus included 44 articles published between 1976 and 2024. The results identify four thematic blocks: (i) product and market diversification strategy, (ii) associativity strategy, (iii) quality and sustainability strategy, and (iv) international marketing strategy, where scientific production is concentrated in China, the United Kingdom and the United States, with little participation from Latin America. As demonstrated by the study, the integration of export strategies is a pivotal factor contributing to the enhancement of companies' commercial performance in international markets. This phenomenon has been shown to consolidate and balance the sustainability and competitiveness of agro-export chains in the agricultural sector.

title: SBC LTER: REEF: Net primary production, growth and standing crop of Macrocystis pyrifera in Southern California

description: The giant kelp Macrocystis pyrifera forms
 subtidal forests on shallow reefs in temperate regions of the
 world. It is one of the fastest-growing multicellular autotrophs
 on Earth and its high productivity supports diverse marine food
 webs. In 2008, we published a method for estimating biomass and
 net primary production (NPP) of giant kelp along with five years
 of data, to provide a more integrated measure of NPP than those
 yielded by previous methods. Our method combines monthly field
 measurements of standing crop and loss rates with a model of kelp
 biomass dynamics to estimate instantaneous mass-specific growth
 rates and NPP for each season of each year. We have since improved
 our approach to account for several previously unresolved sources
 of biomass loss. These improvements have led to a near doubling of
 our prior estimates of growth and NPP. At our site with the most
 persistent stand of giant kelp, NPP averages ~5.2 kg dry mass
 m-2 y-1 and
 results from the rapid growth (~3.5% per day) of a relatively
 small standing biomass (~ 0.4 kg dry mass
 m-2 on average) that turns over ~ 12
 times annually. Here we provide revised estimates of seasonal
 biomass, growth and NPP for the five years covered by our previous
 publication (2002-2006), along with an additional data collect
 since then (2007-present). We also present updated relationships
 for predicting giant kelp biomass and NPP from much more easily
 obtained measurements of frond density. These data can be used to
 understand the mechanisms that drive variation in giant kelp NPP
 at a wide range of temporal scales.

title: Data and Code From: AI-Based bread quality assessment using image processing techniques and the developed BQe-CNN

description: Ensuring consistent bread quality is vital for maintaining industry standards, reducing waste, and keeping consumer satisfaction. Traditional methods of bread quality analysis which rely on manual inspection, are often subjective, time-consuming, and prone to inconsistencies, while modern analysis techniques, though available, tend to be prohibitively expensive. This study introduces an AI-driven approach that leverages advanced image processing techniques to automate and enhance the accuracy of bread quality assessment. By extracting key features such as porosity, texture, and air cell structure, the proposed Bread Quality Enhanced Convolutional Neural Network (BQe-CNN) offers a more precise analysis of bread parameters. The model achieved classification accuracies of 92% for bread colors and 88% for quality levels, significantly outperforming manual methods. By leveraging enhanced layers like residual connections and attention mechanisms, the model efficiently captured fine details in bread images, making it highly effective at detecting subtle variations in texture and air cell distribution. While the model demonstrates high performance in quantitative analysis, it is important to note that artisan scoring—characterized by detailed aesthetic evaluations integral to traditional bread-making—remains a challenging domain for automation. This limitation presents an opportunity to further enhance the model's capabilities by integrating advanced algorithms or hybrid approaches, bridging the gap between precise computational analysis and the specific requirements of artisan scoring. Nevertheless, the BQe-CNN's ability to provide real-time, automated quality control is a dependable and transformative tool, optimizing production, reducing waste, and complementing human expertise in a cost-effective manner. These image processing techniques allow for real-time, automated quality control, optimizing production and reducing waste. This novel approach, rooted in visual analysis of product characteristics, represents a significant leap forward in achieving consistency and scalability in bread quality control for the baking industry.Included is a subsample of images of bread of different color and porosity, examples of the processed images, a data descriptor README, metadata for the bread images, porosity values for the bread images, and MatLab code.
