Los objetos de adorno personal asociados al esqueleto mesolítico Braña-2.

Survey excavation at the Brana-Arintero cave, Cantabria, Spain, has yielded two ochred skeletons attributed to the Mesolithic and directly dated to 6980±50 BP (Brana-1, Beta-226472) and 7030±50 BP (Brana-2, Beta-226473), the first of which lying on a bed made of broken stalagmites (Prada et al. 2007 ; Vidal et al. 2008). Both are adult males. Twenty-four perforated red deer canines were associated with the Brana-2 individual. Zooarchaeological analysis of these personal ornaments reveals the exclusive use of male canines, the preference for adult individuals, and, with a single exception, the used of unpaired teeth. Over-representation of unpaired teeth is interpreted as reflecting acquisition over a long time span through an exchange network. The technological analysis of perforations indicates that all the teeth were perforated with the same technique, i.e. by thinning the root by scraping and subsequently piercing it by the rotation of a lithic point. Recorded variations in the motions applied during the work suggest different craftsmen were involved in the process. Wear pattern indicates the canines were originally embroidered on a cloth and worn for a long period of time. Few crowns were modified by abrasion, perhaps to increase morphological homogeneity. Others bear traces indicating a possible use as crutch for pressure retouch. Study of recorded occurrences of perforated red deer canines at European Mesolithic sites identifies a northern region in which this ornament is widely used. Brana-Arintero cave is located at the very southern limit of this distribution area. Since red deer is attested all over Europe during the Atlantic period (Sommer et al. 2008) the preference for the use of canines of this species in the North of Europe is the likely expression of a cultural choice.
A neural network model for prediction of deoxynivalenol content in wheat grain based on weather data and preceding crop

Deoxynivalenol (DON) is the most prevalent Fusarium toxin in Czech wheat samples and therefore forecasting this mycotoxin is a potentially useful tool to prevent it from entering into food chain. The data about DON content in wheat grain, weather conditions during the growing season and cultivation practices from two field experiments conducted in 2002–2005 were used for the development of neural network model designed for DON content prediction. The winning neural network is based on five input variables: a categorial variable – preceding crop, and continuous variables – average April temperature, sum of April precipitation, average temperature 5 days prior to anthesis, sum of precipitation 5 days prior to anthesis. The most important input parameters are the preceding crop and sum of precipitation 5 days prior to anthesis. The weather conditions in April, which are important for inocu lum formation on crop debris are also of important contribution to the model. The weather conditions during May and 5 days after anthesis play only an insignificant role for the DON content in grain. The effect of soil cultivation was found inferior for model function as well. The correlation between observed and predicted data using the neu ral network model reached the coefficient R 2 = 0.87.
Indices of sarcopenic obesity are important predictors of finite element analysis-derived bone strength in older adults with obesity

Background The expanding population of older adults with obesity is a public health challenge, in part, because of the increased risk of fractures despite normal or high bone mineral density. Potential factors predisposing to fractures in this group include sarcopenia associated with obesity and impaired bone quality. We aimed to determine the contribution of sarcopenic obesity (SO) indices to bone strength as assessed by microfinite element analysis (μFEA) of high-resolution peripheral quantitative computed tomography (HR-pQCT). Methods One-hundred eighty-nine older (age ≥ 65 years) adults with obesity (BMI ≥ 30 kg/m2) participated in lifestyle intervention trials at our medical center. All underwent baseline measurements of bone strength (failure load and stiffness) using μFEA from HR-pQCT of the distal radius and tibia. In addition, SO indices [appendicular lean mass/weight (ALM/W) and percent body fat (FM%)] by dual-energy X-ray absorptiometry and handgrip strength (HGS) by dynamometry were assessed. SO was diagnosed and staged based on the 2022 ESPEN and EASO expert consensus statement. Results Both ALM/W and HGS were positively correlated explaining 28% to 36% of the variance in failure load and stiffness at the distal radius and tibia (all p < 0.001). In contrast, FM% was negatively correlated explaining 22% to 31% of the variance in failure load and stiffness at the distal radius and tibia (all p < 0.001). The associations of SO indices with failure load and stiffness remained significant after controlling for age, sex, race/ethnicity, diabetes, and 25-OH vitamin D (ALM/W: R 2 = 0.301 to 0.448, HGS: R 2 = 0.346 to 0.472, FM%: R 2 = 0.299 to 0.432) (p < 0.001 to 0.011). SO was diagnosed in 75/189 (40%) participants with 66/75 (88%) having functional or metabolic complications (stage II). Participants with SO had lower failure load and stiffness at the distal radius than participants with no SO (both p < 0.05). Conclusion These findings demonstrate that lower muscle mass and strength and higher fat mass may impair bone quality. Therefore, interventions that focus on preserving muscle mass and strength while reducing fat mass may be important to decrease fracture risk when older adults with obesity undertake lifestyle intervention therapy.

True Triaxial Tests on Normally Consolidated Clay and Analysis of the Observed Shear Behavior Using Elastoplastic Constitutive Models

ABSTRACT Drained true triaxial tests on a normally consolidated clay under a constant mean principal stress condition are performed using a newly made apparatus in which two principal stresses are applied by rigid plates and the other principal stress by a chamber water pressure. After checking the accuracy of the tests, the deformation and strength characteristics of clay in three-dimensional stresses are experimentally discussed, and the test results are compared with the analytical results by the well-known Cam-clay model and those by the tij-clay model which has recently been developed with reference to the extended concept of “Spatially Mobilized Plane”. Although the Cam-clay model does not explain uniquely the observed shear behavior of clay in three-dimensional stresses, the tij-clay model takes into account adequately the influence of the intermediate principal stress on the behavior of clay and can describe the deformation and strength characteristics of clay with unified values of soil parameters which are easily determined from a conventional triaxial test and others.
Phenolic Compounds in Fractionated Blackcurrant Leaf Extracts in Relation to the Biological Activity of the Extracts

The aim of this study was to determine the relationship between antioxidant and anticancer properties of extracts from blackcurrant (Ribes nigrum L.) leaves and their fractions and chemical contents. Dried ethanolic extract was divided into three fractions using solid phase extraction: aqueous (F1), 40% MeOH (F2), and 70% MeOH (F3). Both the extract and the fractions were analyzed in terms of antiradical activity (DPPH• and ABTS+•), total phenolic compounds, and total flavonoids. The antitumor potential of the fractions was evaluated in vitro on human colorectal (HCT 116) and prostate (PC-3) cancer cells. Phenolics were identified using HPLC-QTOF-MS, and twelve compounds were quantified by HPLC-DAD. Finally, principal component analysis was carried out to assess the relationship between the tested factors. The results confirmed that blackcurrant leaves are a rich source of phenolics with high antioxidant activity and anticancer properties. It was demonstrated that the F2 fraction had the highest content of phenolics and the highest antiradical activity. Additionally, only this fraction showed cytotoxic activity against HCT 116 cells. It was confirmed that both the blackcurrant leaf extract and its fractions are a promising source of condensed active compounds and can be used as natural functional food additives.
SPATIAL STRATEGY FOR INFORMATION SOCIETY: RETHINKING SMART CITY

This study examines the impact of information society from the spatial perspective; reviews the basic impact of IT on urban space in terms of travel behavior, functional organization, and space image; and then expounds the strategy for urban space planning. Under the influences of information technology, changes in the urban functional organization, be it agglomeration or diffusion, and in the demand of transport travel have increased the complexity of the urban space structure, while city image delivered by digital media contributes to blending real space and virtual space together. According to relevant researches, information society has been an objective existence, whereas smart city can be perceived as the planning model embodied with a promising vision. Therefore, spatial planning in the context of information cityshould be conducted from the perspectives of both instrumental rationality and critique of reason. On the basis of that, this study proposes that: smart city construction should foremost improve the space effi ciency with the help of IT, and pay attention to the space probability during the process of urban development, so as to bestow spaces of all levels the adaptability to respond to different scenarios; on the other hand, the space strategy of smart city should return to the people-oriented values, shape localized spaces so as to cope with the challenges of global mobility, and to ultimately achieve sustainable regional development.
UAV Technology for Precision Weed Detection and Management

In India population increases rapidly day-by-day, therefore food demand also increases. Traditional farming is insufficient to meet these demands. Thus, Unmanned Aerial Vehicles (drones) were introduced, enabling Weed Management in less time, efficient use of herbicide and pesticide to bring sustainability to the environment and their resources. One of the most detrimental biotic variables in agriculture, weeds significantly reduces yields across the globe. Weed patches from crop fields can be identified by using drone sensors. Drone camera sensors can optimize weed in relation to leaf density, chlorophyll concentration and other plant canopy characteristics. The article emphasizes weed detection and management by the use of potential sensors of Unmanned Aerial Vehicles (drones) technology for better agriculture output.
Seasonal and Storm Event‐Based Dynamics of Dissolved Organic Carbon (DOC) Concentration in a Mediterranean Headwater Catchment

This study investigates the spatial and temporal dynamics of Dissolved Organic carbon (DOC) concentration in a Mediterranean headwater catchment (Turbolo River catchment, southern Italy) equipped with two multi‐parameter sondes providing more than two‐year (May 2019–November 2021) continuous high‐frequency measurements of several DOC‐related parameters. The sondes were installed in two nested sections, a quasi‐pristine upstream sub‐catchment and a downstream outlet with anthropogenic water quality disturbances. DOC estimates were achieved by correcting the fluorescent dissolved organic matter—fDOM—values through an original procedure not requiring extensive laboratory measurements. Then, DOC dynamics at the seasonal and storm event scales were analyzed. At the seasonal scale, results confirmed the climate control on DOC production, with increasing background concentrations in hot and dry summer months. The hydrological regulation proved crucial for DOC mobilization and export, with the top 10th percentile of discharge associated with up to 79% of the total DOC yield. The analysis at the storm scale using flushing and hysteresis indices highlighted substantial differences between the two catchments. In the steeper upstream catchment, the limited capability of preserving hydraulic connection over time with DOC sources determined the prevalence of transport as the limiting factor to DOC export. In the downstream catchment, transport‐ and source‐limited processes were observed almost equally. The correlation between the hysteretic behavior and antecedent precipitation was not linear since the process reverted to transport‐limited for high accumulated rainfall values. Exploiting high‐resolution measurements, the study provided insights into DOC export dynamics in nested headwater catchments at multiple time scales.
Highly potassic lamprophyre from the Sera Plateau in the Chugoku Mountains, SW Japan

Highly potassic mafic rocks are rarely found in Southwest Japan Arc. Recently, we found highly potassic lamprophyre (minette) from the northeastern part of the Sera Plateau in the Chugoku Mountains. It consists of phenocrysts of phlogopite (mg 85.6, TiO2 4.08-4.18), clinopyroxene (diopside-salite), olivine (mg 84.5) and apatite set in a groundmass of poikilitic sanidine ? anorthoclase, phlogopite, clinopyroxene, apatite and titanomagnetite. The minette is high in K2O content (5.88 wt%) and K2O/Na2O ratio (3.51). The rock shows relatively high concentration of MgO, Ni and Cr, and is strikingly enriched in incompatible elements, particularly Rb, Sr, Ba, Zr and P. The MORB-normalized pattern of the minette is most closely matched by certain alkali basalts of island arcs and continental margins, having negative Nb-anomalies. However, it is highly enriched in incompatible elements compared with island arc basalts. This suggests that the source for the minette is similar to that for the island arc alkali basalt but spiked with K, Rb, Sr, Ba, Zr and P prior to melting.
Tibial Plateau Leveling Osteotomy following Tibial Tuberosity Advancement Cage Removal: A Case Report

Simple Summary Persistent knee joint instability has been recognized as a potential postoperative consequence after Tibial Tuberosity Advancement (TTA) causing chronic lameness. A six-year-old male Labrador retriever (38 kg) with persistent lameness lasting six months after TTA Rapid surgery has been examined. During orthopedic examination, the lameness was subjectively graded 3/5 and the positive drawer and tibial compression tests were performed. Radiographical measurements were performed; the preoperative tibial plateau angle was 27° and the patella ligament angle relative to the tibial plateau was 102°. The decision was made to completely remove the TTA Rapid cage and all screws to have enough room to perform a TPLO and apply a 3.5 LCP plate. Long-term follow-up showed radiologically excellent healing with fusion of the gap and disappearance of the osteotomy line. Six months postoperatively, no lameness was detected at a walk and trot. The owner was completely satisfied and reported the dog being free of lameness even after long walks. Abstract The purpose of this case report is to describe the functional and clinical outcome of a tibial plateau leveling osteotomy (TPLO) in a dog with joint instability and persistent lameness following a Tibial Tuberosity Advancement surgery (TTA) Rapid. A six-year-old male Labrador retriever (38 kg) with a tibial plateau angle of 27° and a patella ligament to tibial plateau angle of 102° and persistent lameness lasting six months after TTA Rapid surgery has been examined. During orthopedic examination, the lameness was subjectively graded 3/5 and the positive drawer and tibial compression tests were performed. The TTA Rapid cage and all screws were completely removed from the tibia to have enough room to perform a TPLO radial cut. A lameness score evaluation, client satisfaction and radiographic follow-up were performed at 4 weeks, 8 weeks and 6 months postoperatively. Long-term follow-up showed radiologically excellent healing with fusion of the gap and disappearance of the osteotomy line. Six months postoperatively, no lameness was detected at a walk and trot. The owner was completely satisfied and reported the dog being free from lameness even after long walks. No complications related to the TPLO surgery occurred.
Effect of Segmented Optical Axial Length on the Performance of New-Generation Intraocular Lens Power Calculation Formulas in Extremely Long Eyes

Purpose: To evaluate the performance of traditional vergence formulas with segmented axial length (AL) compared to traditional composite AL in extremely long eyes, and to determine whether the segmented AL can be extended to the new-generation formulas, including the Barrett Universal II, Emmetropia Verifying Optical 2.0 (EVO2), Hill-RBF 3.0 (Hill3), Kane, and Ladas Super formula (LSF) formulas in extremely long eyes. Setting: National Hospital. Organization, Tokyo Medical Center, Japan. Design: Retrospective case series. Methods: Consecutive patients who underwent uncomplicated cataract surgery implanted with a three-piece intraocular lens between December 2015 and March 2021 were retrospectively reviewed. The composite AL was measured with a swept-source optical coherence tomography (SS-OCT) biometer using a mean refractive index. The segmented AL was calculated by summing the geometric lengths of the ocular segments (cornea, aqueous, lens, and vitreous) using multiple specific refractive indices based on the data obtained by the SS-OCT-based biometer. When refraction was measured at three months postoperatively, the median absolute errors (MedAEs) were calculated with two ALs for each formula. Results: The study included 31 eyes of 22 patients. The segmented AL (30.45 ± 1.23 mm) was significantly shorter than the composite AL (30.71 ± 1.28 mm, p < 0.001). The MedAEs were significantly reduced when using segmented AL for SRK/T, Haigis, Hill3, and LSF, compared to those obtained using composite AL (0.38 vs. 0.62, 0.48 vs. 0.79, 0.50 vs. 0.90, 0.34 vs. 0.61, p < 0.001 for all formulas, respectively). On the contrary, the MedAE obtained by Kane with segmented AL was significantly worse compared to the one with composite AL (0.35 vs. 0.27, p = 0.03). Conclusion: In extremely high myopic eyes, the segmented AL improves the performance of SRK/T, Haigis, Hill3, and LSF formulas compared to the composite AL, while the segmented AL worsens the prediction accuracy of the Kane formula.
Pricing optimization of product line with value-added services considering consumer choice behavior

ABSTRACT The global economy is transitioning from product economy to service economy, and the optimization of product line with value-added services is one of the important issues faced by enterprises. Therefore, this paper studies the pricing optimization of product line with value-added services considering consumer choice behavior. First, we apply the multinomial logit (MNL) model to simulate consumer choice behavior, and establish a MNL-based product line pricing optimization model considering value-added services. Then, the optimal pricing strategies for products and services are solved for three different scenarios: single product with service, homogeneous products with services, and heterogeneous products with services. Finally, through numerical experiments, we analyze the changing trends of the optimal pricing, market share and profit of products line with value-added services with some impact factors, such as product quality, service level, consumer sensitivity, and number of products under three different scenarios. We also obtain some managerial implications when an enterprise develops product line with value-added service.
Mutual Coupling Reduction in Compact MIMO Antenna Operating on 28 GHz by Using Novel Decoupling Structure

This article presents an antenna with compact and simple geometry and a low profile. Roger RT6002, with a 10 mm × 10 mm dimension, is utilized to engineer this work, offering a wideband and high gain. The antenna structure contains a patch of circular-shaped stubs and a circular stub and slot. These insertions are performed to improve the impedance bandwidth of the antenna. The antenna is investigated, and the results are analyzed in the commercially accessible electromagnetic (EM) software tool High Frequency Structure Simulator (HFSS). Afterwards, a two-port multiple–input–multiple–output (MIMO) antenna is engineered by orthogonalizing the second element to the first element. The antenna offers good value for mutual coupling of less than −20 dB. The decoupling structure or parasitic patch is placed between two MIMO elements for more refined mutual coupling of the proposed MIMO antenna. The resultant antenna offers mutual coupling of less than −32 dB. Moreover, other MIMO parameters like envelop correlation coefficient (ECC), mean effective gain (MEG), diversity gain (DG), and channel capacity loss (CCL) are also studied to recommend antennas for future applications. The hardware model is fabricated and tested to validate the results, which resembles software-generated results. Moreover, the comparison of outcomes and other important parameters is performed using published work. The outcome of this proposed work is performed using already published work. The outcomes and comparison make the presented design the best option for future 5G devices.
SIW Multifunctional Device Integrated With Multi-State Diplexer and Multi-Channel Filtering Crossover

A multifunctional substrate integrated waveguide (SIW) device integrated with multi-state diplexer (MSD) and multi-channel filtering crossover (MCFC) is proposed in this brief. In addition, the MSD and MCFC functions can also coexist without mutual influence. The proposed device solves the problem that current multifunctional devices only share a single state, thereby being very suitable for frequency-hopping systems with high circuit utilization. In design, <inline-formula> <tex-math notation="LaTeX">$\text{N}\times \text{M}$ </tex-math></inline-formula> SIW resonant cavities are cascaded, and three resonant modes, TE102, TE201, and TE301, are employed to realize three filtering channels. By properly arranging the feedlines and inductive coupling windows between the adjacent cavities, M+2-state diplexer and <inline-formula> <tex-math notation="LaTeX">$\text{N}+\text{M}$ </tex-math></inline-formula>/2 crossed filtering channels are implemented. For validation, a prototype integrating with four-state diplexer (FSD) and two-channel filtering crossover (TCFC) is designed and fabricated, and the measured results show good agreement with the simulated ones.
