We report new results from quantum calculations of energy-transfer processes
taking place in interstellar environments and involving two newly observed
molecular species: C5N− and C7N− in
collision with He atoms and p–H2 molecules. These species are part of
the anionic molecular chains labeled as cyanopolyynes, which have been observed
over the years in molecule-rich circumstellar envelopes and in molecular clouds.
In the present work, we first carry out new ab initio calculations for the
C7N− interaction potential with He atoms and then
obtain state-to-state rotationally inelastic cross sections and rate
coefficients involving the same transitions, which have been observed
experimentally by emission in the interstellar medium (ISM) from both of these
linear species. For the C5N−/He system, we extend the
calculations already published in Biwas et al. to compare more directly the two
molecular anions. We extend further the quantum calculations by also computing
in this work collision rate coefficients for the hydrogen molecule interacting
with C5N−, using our previously computed interaction
potential. Additionally, we obtain the same rate coefficients for the
C7N−/H2 system by using a scaling procedure
that makes use of the new C7N−/He rate coefficients, as
discussed in detail in the present paper. Their significance in affecting
internal state populations in ISM environments where the anionic cyanopolyynes
have been found is analyzed by using the concept of critical density indicators.
Finally, similarities and differences between such species and the comparative
efficiency of their collision rate coefficients are discussed. These new
calculations suggest that, at least for the case of these longer chains, the
rotational populations could reach local thermal equilibrium conditions within
their observational environments.
CO Mapping of Cygnus-X—Volume Density Distribution
Authors: Baade Jonah C. , Kong Shuo , Bieging John H. , Folkers Thomas
Published: December 2023

We present CO(2-1) and 13CO(2-1) maps of the Cygnus-X molecular cloud complex using the 10 m Heinrich Hertz Submillimeter Telescope. The maps cover the southern portion of the complex, which is strongly impacted by the feedback from the Cygnus OB2 association. Combining CO(1-0) and 13CO(1-0) maps from the Nobeyama 45 m Cygnus-X CO Survey, we carry out a multitransition molecular line analysis with RADEX and derive the volume density of velocity-coherent gas components. We select those components with a column density in the power-law tail part of the column density probability distribution function (N-PDF) and assemble their volume density into a volume density PDF (ρ-PDF). The ρ-PDF exhibits a power-law shape in the range of 104.5 cm−3

105.5 cm−3 with a fitted slope of α = −1.12 ± 0.05. The slope is shallower than what is predicted by simulations of rotationally supported structures or those undergoing gravitational collapse. Applying the same analysis to synthetic observations with feedback may help identify the cause of the shallow slope. The ρ-PDF provides another useful benchmark for testing models of molecular cloud formation and evolution.

Published: December 2023

Wave–particle interactions play a crucial role in transferring energy between electromagnetic fields and charged particles in space and astrophysical plasmas. Despite the prevalence of different electromagnetic waves in space, there is still a lack of understanding of fundamental aspects of wave–particle interactions, particularly in terms of energy flow and velocity-space characteristics. In this study, we combine a novel quasilinear model with observations from the Magnetospheric Multiscale mission to reveal the signatures of resonant interactions between electrons and whistler waves in magnetic holes, which are coherent structures often found in the Earth’s magnetosheath. We investigate the energy transfer rates and velocity-space characteristics associated with Landau and cyclotron resonances between electrons and slightly oblique propagating whistler waves. In the case of our observed magnetic hole, the loss of electron kinetic energy primarily contributes to the growth of whistler waves through the n = −1 cyclotron resonance, where n is the order of the resonance expansion in linear Vlasov–Maxwell theory. The excitation of whistler waves leads to a reduction of the temperature anisotropy and parallel heating of the electrons. Our study offers a new and self-consistent understanding of resonant energy transfer in turbulent plasmas.
Wireless Sensor Network Coverage Optimization for Internet of Things
Authors: Xu Yunwu , Li Yan
Published: December 2023

The objective of this work is to improve the existing Wireless Sensor Network coverage optimization method. The pigeon-inspired optimization algorithm was first evaluated, and its shortcomings were noted. The pigeon-inspired optimization method was then enhanced with the good point set, Yin-Yang optimization algorithm, and opposition-based learning. To test the improved algorithm, five representative standard functions were chosen: sphere function (f1), Rosenbrock function (f2), Levy function (f3), Schwefel function (f4), and Levy function N.13 (f5). The algorithm's speed of convergence may be determined by the first two functions, which are unimodal. The final three functions, which are multimodal, can extract several local optimal values from the local optimum. In comparison with other known algorithms, the improved Yin-Yang PIO algorithm showed the highest optimization accuracy and stability. Three sets of experiments were performed to optimize the WSN coverage with different parameters. The first series of experiments suggest that Yin–Yang PIO has the best optimization effect, with a coverage rate of 99.51% (10.22% higher with PIO and 6.41% higher compared with PSO). The second and third series of experiments show that Yin-Yang PIO significantly increased the WSN coverage ratio, up to 99.9%. The algorithm can be applied to optimize WSN coverage in various environments. Future research can extend the research scope to include other optimization problems in IoT.

Authors: Oliveira Ana Cristina Alves de , Spohn Marco Aurélio , Fetzer Christof , Do Le Quoc , Martin André
Published: December 2023

Data-as-a-Service (DaaS) is a branch of cloud computing that supports “querying the Web”. Due to its ultrahigh scale, it is essential to establish rules when defining resources’ costs and guidelines for infrastructure investments. Those decisions should prioritize minimizing the incidence of agreement breaches that compromise the performance of cloud services and optimize resources’ usage and services’ cost. This article aims to address the cost problem of DaaS by developing a model that optimizes the costs of querying distributed data sources over virtual machines spread across multisite data centers. We have designed and analyzed a cost model for DaaS, besides implementing a scheduling system to perform a cost-based VM assignment. To validate our model, we have studied and characterized a real-world DaaS system’s network and processing workloads. On average, our cost-based scheduling performs at least twice as well as the traditional round-robin approach. Our model also supports load balancing and infrastructure scalability when combined with an adaptive cost scheme that prioritizes VM allocation within the underutilized data centers and avoids sending VMs to data centers in the eminence of becoming over-utilized.

The Eastern common groundhopper, Tetrix japonica, is a pygmy grasshopper species widely distributed in the Eastern Palearctic region, and shows a high degree of phenotypic variation. The classification of Tetrix japonica is difficult and frequently involved errors. Among the many species of Tetrigidae that have been described in China within the last decades, many synonyms of Tetrix japonica were found. The type specimens of many species deposited in the Chinese museums have been re-examined and as a result, Tetrix japonica is systematically revised. Based on the results of this review, 23 new synonyms of Tetrix japonica are proposed: Coptotettix circinihumerus Zheng & Deng, 2004, syn. nov.; Coptotettix emeiensis Zheng, Lin & Zhang, 2012, syn. nov.; Euparatettix rongshuiensis Zheng, 2005, syn. nov.; Euparatettix zayuensis Zheng, Zeng & Ou, 2011, syn. nov.; Macromotettix nigritubercle Zheng & Jiang, 2006, syn. nov.; Macromotettix yaoshanensis Zheng & Jiang, 2000, syn. nov.; Tetrix albistriatus Yao & Zheng, 2006, syn. nov.; Tetrix albomaculatus Zheng & Jiang, 2006, syn. nov.; Tetrix albomarginis Zheng & Nie, 2005, syn. nov.; Tetrix cenwanglaoshana Zheng, Jiang & Liu, 2005, syn. nov.; Tetrix cliva Zheng & Deng, 2004, syn. nov.; Tetrix duolunensis Zheng, 1996, syn. nov.; Tetrix grossovalva Zheng, 1994, syn. nov.; Tetrix jiuwanshanensis Zheng, 2005, syn. nov.; Tetrix latipalpa Cao & Zheng, 2011, syn. nov.; Tetrix liuwanshanensis Deng, Zheng & Wei, 2007, syn. nov.; Tetrix qinlingensis Zheng, Huo & Zhang, 2000, syn. nov.; Tetrix rectimargina Zheng & Jiang, 2004, syn. nov.; Tetrix ruyuanensis Liang, 1998, syn. nov.; Tetrix xianensis Zheng, 1996, syn. nov.; Tetrix xinchengensis Deng, Zheng & Wei, 2007, syn. nov.; Tetrix yunlongensis Zheng & Mao, 2002, syn. nov.; Tetrix zhoushanensis Gao, Liu & Yin, 2022, syn. nov. It is expected that there will be the discoveries of more synonyms of this and other Tetriginae species from the Eastern Palearctic.
Taxonomic review of the Calotes versicolor complex (Agamidae, Sauria, Squamata) in China, with description of a new species and subspecies
Authors: Huang Yong , Li Hongyu , Wang Yilin , Li Maojin , Hou Mian , Cai Bo
Published: December 2023

Calotes wangisp. nov., a new species of the agamid genus Calotes Cuvier, 1817, from southern China and northern Vietnam, is described. This species can be distinguished from all known congeners by a combination of morphological characteristics and genetic divergence in the mitochondrial tRNA, ND2, and CO1 genes. Molecular phylogenetic analysis revealed that the new species was formed as a monophyletic group and that considerable genetic divergence existed between its congeners (minimum p-distance, 4.6%). Calotes wangisp. nov. is distinguished by a combination of the following characteristics: average SVL < 90 mm for adult males; 10–14 dorsal eyelid scales; scales on side of neck and adjacent shoulder area pointing obliquely upward; keels on neck scales weakly to strongly developed; fold in front of the shoulder absent; pair of dark triangular patches extending from the front of the shoulder to the jaw angles; and orange coloration of the tongue. Calotes wangisp. nov. is similar to C. irawadi but differs in having scales between the nasal shield and the orbit and a fourth toe with a claw that can reach between the eyes and tympanum (even to the snout when hind the limbs are adpressed forward). Phylogenetic analyses revealed two well-supported subspecies, Lineages A and B in C. wangisp. nov., with mean uncorrected p-distances between them of 2%. We propose that Lineage A, which is mainly from the central and southern Wuzhi Mountains on Hainan Island, is a subspecies, C. w. hainanensisssp. nov. Lineage B mainly comprises individuals from other sites on the island plus the adjacent mainland, and is described as subspecies, C. w. wangissp. nov. A diagnostic key to all Calotes species of China is also provided.

A novel method for mobile application recognition in encrypted channels
Authors: Zhai Jiangtao , Wang Zihao , Duan Kun , Wang Tao
Published: December 2023

In the field of mobile application traffic analysis, existing methods for accurately identifying encrypted traffic often encounter challenges due to the widespread adoption of encryption channels and the presence of background traffic. Consequently, this study presents a novel mobile application traffic identification model that is in encrypted channels. The proposed model utilizes an adaptive feature extraction technique that combines Convolutional Neural Networks (CNNs) and Gated Recurrent Units (GRUs) to effectively extract abstract features from encrypted mobile application traffic. Additionally, by employing a probability-based comprehensive analysis to filter out low-confidence background traffic interference, the reliability of recognition is further enhanced. Experimental comparisons are conducted to validate the efficacy of the proposed approach. The results demonstrate that the proposed method achieves a remarkable classification accuracy of 95.4% when confronted with background traffic interference, surpassing existing techniques by over 15% in terms of anti-interference performance.
A Study on a Novel Process Combines Cutting and Joining by an Automatic Lathe
Authors: Tanaka Hidetake
Published: December 2023

The Swiss-type automatic lathe is designed for continuous mass production of the same product. In the research, the authors propose a combined turning process in which a joining process using the frictional welding method is introduced into the automatic lathe. If the joining process is performed with a Swiss-type automatic lathe, it is expected that the problem of a large amount of residual material due to the mechanical structure can be solved. Generally, the friction welding method is performed by a dedicated machine and is pressure controlled by a hydraulic power source, however in the case of an automatic lathe, friction welding is controlled by the feed length and feed rate. The low rigidity of automatic lathes is also concerned. In the study, the authors investigated the tensile strength and rotational bending fatigue strength of the A6061 bonding material to investigate and quantitatively evaluate the optimum friction welding conditions that can obtain good bonding results in the friction welding method using a multi-axis automatic lathe. Upset speed was the most influential factor for tensile strength and friction rotation speed was good at about 4000 rpm. This fact suggests that excessive heat input leads to a decrease in tensile strength. The tensile strength was equivalent to that of the annealed material. It also seems that the air-cooled annealing phenomenon occurs during the friction welding process. The results of rotational bending fatigue strength were similar to those of the annealed material. It is clarified that friction welding with an automatic lathe is feasible, however, the strength of the bonded material is reduced to the same level as that of the annealed material.

Authors: Okada Masato , Yoshita Seito , Nikawa Makoto , Hasegawa Naho
Published: December 2023

A novel edge treatment method that utilizes a tip-burnishing process with an active rotary tool developed by the authors was proposed. Two types of burnishing process experiments were conducted using the tip-burnishing process to deburr the workpiece edge and create a sharp cutting edge. Furthermore, an evaluation test for the cutting performance of the sharp edge, which was treated using the developed burnishing process, was conducted. In the deburring experiment, superior deburring was achieved by generating a sliding effect orthogonal to the burr generation direction. An experiment was conducted for evaluating the sharpening of the cutting edge; it was observed that the cutting-edge angle decreased due to the burnishing process. A cutting performance test was conducted using a wedge-shaped workpiece before and after burnishing. The cutting performance of the workpiece was quantitatively evaluated based on the load and stroke required for the cutting of the sheet material.

Published: December 2023

Although the Incremental Sheet Forming (ISF) technology has been studied and applied from the last decade of the previous century with more than 30 years of experiences and ameliorations of the researchers of this field, but the ability of deformation of the formed material sheet still has remained in a restrictive modest value. This sheet forming technology could be divided into 2 mains branches: Single Point Incremental Forming (SPIF) and Two Point Incremental Forming (TPIF) wherein the first one is usually applying in research and the second branch is used in production. The ISF is suitable for forming sheet for a single product or for small batch production with a great advantage of a no-need pestle and mold manufacture in advance, but the formability of formed sheet material cannot bigger than a limited formed angle of about 80o that depends on the material and the forming parameters. There are some ameliorations for increasing the formability of the formed sheet such as heating the formed sheet in Hot SPIF or Multistage SPIF (MSPIF)… All the effort and amelioration measures are confronted with different difficulties. In this paper, we concentrate to study on the MSPIF technology on stainless steel SUS304 by simulation method with the proof of experimental method. The results were also compared to the simple SPIF to show its own pros and cons on the related field such as the technology, the productivity and the lubrication.

Published: December 2023

Electropolishing has been widely used for surface finishing of metallic products in the industry, owing to its excellent capability of producing metallic components with a homogeneously smooth surfaces. However, this treatment is often constrained by the long duration required for the processing. Therefore, an improvement in this process is needed. The aim of this research is to introduce the use of electropolishing with circulated electrolytes for improving the surface finish of brass. In this work, electropolishing was carried out by using circulated H2SO4 electrolyte for 10 to 30 min in a customized electropolishing chamber. The effect of this treatment on surface morphology, surface roughness, and thickness reduction of the brass specimen was determined. The results showed a better capability of electropolishing with circulated electrolyte in decreasing the brass roughness, i.e., by 84%, than that without electrolyte circulation which only reached 45% during 30 min of the treatment.

Published: December 2023

Lichen planopilaris (LPP) is the follicular representation of lichen planus which is the prototype of CD8+ T cell mediated inflammatory diseases. In all the variants of LPP clinical hallmark is the scarring alopecia of involved hair follicles in which the scalp hair is the main target. Though the non-inflammatory type alopecia is documented in certain subtypes such as lassueur-graham-little-piccardi (LGLP) and frontal fibrosing cicatricial alopecia (FFA) where it particularly affects the body hair, scarring alopecia of body hair is extremely rare in LPP. Herein we report a case of isolated leg hair involvement in LPP.

Authors: Fernando G.M.O. , Thamilvannan N.
Published: December 2023

Introduction: Batticaloa is the capital city of Batticaloa District situated in Eastern Province of Sri Lanka, which harbors various ethnic groups with different religious backgrounds. The ethnic and religious diversity of population is responsible for variety of food items and dishes unique to the area where demand for food has created a rapidly growing food industry. Food safety standards require all persons involved in handling food to be in perfect hygienic condition in order to prevent contamination with microorganisms and to offer a perfect product to the consumer.

Methods: A descriptive cross sectional study was carried out among food handlers who were working in the most populated PHI regions of Batticaloa MOH area. All workers were interviewed and examined at their workplace and relevant further examination and investigations were carried out at the Skin Clinic, Teaching Hospital, Batticaloa.

Results: 69 (42.3%) out of the total 163 workers had occupational dermatoses (OD), and out of them physical injuries (thermal, cuts/ abrasions) was the commonest [22 (31.88%)]. Second commonest OD was paronychia and occupational contact dermatitis (OCD), which was found only among 12 (17.3%) workers. Irritant contact dermatitis (ICD) was more prevalent (11.5%) than allergic contact dermatitis (ACD) (5.7%) among the workers with OCD. Both personal history of atopy and increased frequency of hand washing were positively correlated with the risk of developing OCD. Acne vulgaris was the commonest none occupational dermatoses (NOD).

Conclusions: Both personal history of atopy and increased frequency of hand washing were positively correlated with the risk of developing OCD. Physical injuries remained the commonest OD which may be contributed by lack of experience and substance abuse.

Authors: Fyzer F. R. , Weerakoon W. A. S. S.
Published: December 2023

Sri Lanka has a pluralistic healthcare system. Allopathic medicine (synonym for the conventional, modern, or western medicine) currently dominates the Sri Lankan healthcare system. Ayurveda and indigenous Sri Lankan medicines (Deshiya Chikitsa) have been employed as complementary medicines. This descriptive crosssectional article evaluates the level of awareness, utilization, and preference for Ayurveda and Sri Lankan indigenous medicine among an adult working population in the Colombo district. The sample consisted of 154 individuals aged 20 to 59 years old selected from two Colombo workplaces. The participants completed a self-administered questionnaire that asked about their awareness, utilization, and preference for Ayurveda and Sri Lankan indigenous medicine. The outcomes were assessed using the criterion of demographic analysis. According to the findings of this article, the majority of participants (98.05%) are aware that Sri Lanka possesses alternative medical systems such as Ayurveda and Sri Lankan indigenous medicine, and that the source of such awareness is their parents. However, knowledge about the medicine’s use and effectiveness is limited. Despite this, 88.07% of participants have received Ayurvedic treatment or indigenous medicine from a qualified practitioner at least once in their lives, 60.93% would prefer to utilize them, and 87.42% would suggest Ayurveda and Sri Lankan indigenous medicines. This article also identifies and provides reasons for the lack of preference for Ayurveda and Sri Lankan indigenous medicine over conventional medicine, along with suggestions to enhance preference for Ayurveda and Sri Lankan indigenous medicine over conventional medicine.
Use of Synthetic Aperture Radar (SAR) imagery on oil spill detection: A case study on the MV X-Press Pearl container ship incident in 2021 in Sri Lanka
Authors:  Madduma Arachchi M. A. S. Manoj
Published: December 2023

Oil spills on the ocean from ships have a strong impact on the environment as well as on human societies. The MV X-Press Pearl container ship incident in 2021 became the worst marine environmental disaster in Sri Lanka due to its powerful impact. Oil leakage from the ship to the ocean continued for months. Synthetic Aperture Radar (SAR) imagery has the advantage of penetrating cloud cover, as well as day and night operating capabilities. Therefore, SAR imagery can be used to detect as well as observe the temporal changes of oil spills. The study in this article aimed to detect the oil spill caused by the MV X-Press Pearl container ship on Sri Lanka’s west coast from May to August 2021 using Sentinel-1 SAR data and measure the temporal changes of the oil slick. Three SAR imageries with Vertical-Vertical (VV) and Vertical-Horizontal (VH) polarization from June, July, and August of 2021 have been processed by applying the orbit file, running the multi-looking algorithm, and making the ellipsoid correction. The possible oil spills have been identified from each set of imagery as dark linear shapes with lengths of 3.1 ±0.012 km with an average reflectance of 15.6 decibels for June and 3.6 ±0.012 km with an average reflectance of 16.5 decibels for the other two months, and the shapes correspond with the oil slick classifications from other literature. The results indicate that the VV polarization is the most suitable to detect oil spills, and that the oil spill from the X-Press Pearl continued from June to the end of August 2021.

To the Editor, In recent years, alternative solutions have been proposed to obtain effective results comparable to TURP, which is currently considered the gold standard, and laser vapo-enucleation techniques (1, 2), but with the possibility of maintaining sexual functions. In recent years there has been a growing trend towards ejaculation preservation. Although the results of TURP (3), and most laser enucleation techniques are undoubted in the Benign Prostatic Hyperplasia (BPH) and Lower Urinary Tract Symptoms (LUTS) management, they often lack in the preservation of ejaculation. All the alternative recently proposed interventions (Rezum, AquaBeam, Urolift, TPLA, i-TIND, LEST) are procedures considered by some authors to be promising in both managing BPO and preserving sexual functions. However, all these methods are limited by a lack of long-term follow-up that would evaluate the efficacy over time, possible complications related to the method and the correct patient selection for a specific method. The aim of this letter is to summarize the available evidence and provide clinicians with practical recommendations on the use of the brand new minimally invasive techniques for the management of BPO.

Для последовательностей из этого класса найдены периоды и распределения элементов, а также другие параметры, представляющие интерес. Приводятся экспериментальные результаты об энтропии и распределениях элементов в конкретных случаях. Кроме того, предложен новый метод построения латинских квадратов, которые можно использовать при построении таких последовательностей.
One Robust Loosely Coupled 4D Millimeter-Wave Image Radar SLAM
Method
Authors: Zhao Yingzhong , Lu Xinfei , Ye Tingfeng
Published: December 2023

In this paper, we introduce one imu radar loosely coupled SLAM method based on
our 4D millimeter-wave image radar which it outputs pointcloud containing xyz
position information and power information in our autonomous vehicles. at common
pointcloud-based slam such as lidar slam usually adopt imu-lidar tightly coupled
structure, which slam front end outputs odometry reversly affect imu
preintegration. slam system badness occurs when front end odometry drift bigger
and bigger or one frame pointcloud match failed. so in our method, we decouple
imu and radar odometry crossed relationship, fusing imu and wheel odometry to
generate one rough pose trajectory as initial guess value for front end
registration, not directly from radar estimated odometry pose, that is to say,
front end registration is independent of imu preintegration. besides, we
empirically propose one idea juding front end registration result to identify
match-less environment and adopt relative wheel odometry pose instead of
registration pose when match belief value(mbv) is false. this can handle some
degrade environment, such as two-side similar greenbelt. finally, to increase
loop detection robustness, we propose two-stage loop detection verify method.
first stage is RS(radius search) method, if it passes loop verify, not enter
second stage, otherwise enter SC(scan context) second stage, after two stage
loop, most real loop can be detected by our slam system. based on above ideas,
at multi scene’s datasets, office park, residential area, open road, underground
parkingplace etc, we can run our slam system successfully, meanwhile at our
office park dataset we compare trajectory precision with tightly-coupled slam
structure and the detected loop number with one stage loop method, exprimental
result proved our proposed method is valid.

The phenomenon of liquid transfer in the liquid tank of the semi-trailer vehicle
for transporting dangerous cargo (SVTDC) during braking is analyzed and the
relevant mathematical model is established. The braking dynamic model of the
SVTDC considering the liquid sloshing in the tank is established, and the model
is verified based on the co-simulation method. Based on the typical conditions,
the braking deceleration and axle load calculation functions of the model are
simulated and analyzed, and the application prospect of the model in the
development of driving automation control strategy is discussed.
Static Gesture Recognition in the cabin Based on 3D-TOF and Low
Computing Power
Authors: Yi Zhigang , Zhou Mingyu , Xue Dan , Peng Shusheng
Published: December 2023

Traditional static gesture recognition algorithms are easily affected by the
complex environment inside the cabin, resulting in low recognition rates.
Compared with RGB photos captured by traditional cameras, the depth images
captured by 3D-TOF cameras can not only reduce the influence of complex
environments inside the cabin, but also protect crew privacy. Therefore, this
paper proposes a low-computing static gesture recognition method based on 3D-TOF
in the cabin. A low-parameter lightweight convolutional neural network (CNN) is
used to train five gestures, and the trained gesture model is deployed on a
low-computing embedded platform to detect passenger gestures in real-time while
ensuring the recognition speed. The contributions of this paper mainly include:
(1) Using the TOF camera to collect 1000 depth images of five gestures inside
the car cabin. And these gesture depth maps are preprocessed and trained by
lightweight convolutional neural network to obtain the gesture classification
model. (2) In the gesture preprocessing stage, a method based on depth
information is designed to quickly locate the depth range of the hand area,
which can quickly locate the depth range of the hand area in real-time. (3) A
low-parameter lightweight convolutional neural network model is proposed, which
has fewer training parameters and can be deployed on a low-computing embedded
platform. The experimental results show that compared with traditional static
gesture recognition algorithms inside the cabin, this method has higher accuracy
and stronger robustness and can recognize passenger gestures in real-time on a
low-computing embedded platform.

Pesnico Vittorio Collona (1492–1547) literarna zgodovina običajno (in upravičeno) uvršča v tok petrarkizma, a je izjemen pojav, ne le zato ker so ženski glasovi v 15. stoletju razmeroma redki, temveč zaradi pesniške izjemnosti, katere pomen presega zgodovinsko dobo njenega življenja. Izvirala je iz mogočnega aristokratskega rodu. V tem okolju je bila deležna vrhunske humanistične izobrazbe, vse življenje se je gibala v različnih eminentnih kulturnih krogih na italijanskem ozemlju, v katerih je igrala zelo dejavno in pomembno vlogo: skratka, bila je izjemna intelektualka v specifičnem okolju renesančne družbe. Že v mladih letih se je uveljavila kot pesnica, sčasoma pa je postala eno najslavnejših pesniških imen 16. stoletja. Njena poezija, napisana v sonetni formi, se po vsebini deli na dve veliki temi: ljubezen in duhovno življenje, tretja, epistolarna poezija, je minorna.
From Values to Religion
Authors: Cipriani Roberto
Published: December 2023

Each individual is guided by values that determine his behaviour. A recurrent distinction concerns the difference between applied values and final values, therefore between values concerning individual practices and values which represent real goals to achieve. The discussion tends to slip onto a juxtaposition of universal values and universal rights, which is to say between human values and human rights. It is not always easy to discern secular values from religious values. The main issue regards those who hold religious and secular values. If religious values are presumably conserved by churches, denominations, confessional organizations, for secular values the State is usually considered to be the main holder. Global values and local values can be in conflict, especially when the same individual has to play a number of different rules. And it must be considered that today migration context in Europe presents different communities with different values.

Pessimism of the Intellect and Optimism of the Will
Authors: Scarpino Antonio
Published: December 2023

Taking up a dictum of Gramsci, in his essay Antonio Scarpino wants “to verify whether there are reasons for a cautious optimism concerning the future.” Based on a critical reflection of uncontrolled economic growth and extreme consumer behaviour in times of polycrisis, he argues both for an intellectual questioning of wrong decisions and misconduct and for the conviction that it is possible to change flawed systems through the power of optimistic will.

Idris Khan:
Authors: Jiménez-Donaire-Martínez Salvador
Published: December 2023

En la última década, el artista británico Idris Khan (Birmingham, 1978) ha obtenido reconocimiento internacional al producir imágenes que evocan y disuelven ideas sobre el tiempo, la memoria y la experiencia. A través de la fotografía y otros medios como la pintura, la escultura o el vídeo, y mediante procesos prolongados tanto de acumulación como de borrado, Khan experimenta con la condensación temporal y la noción de recuerdo. Este texto examina una selección de sus obras desde 2001 hasta la actualidad. El impulso de fotografiar supera largamente nuestra capacidad –o tiempo, o voluntad– para recrearnos en esos recuerdos capturados. El presente trabajo analiza las implicaciones y dinámicas de esta saturación icónica a través de la obra de Khan, poniéndola en relación con ideas de autores y pensadores que abordan esta creciente problemática.
Reproducciones y obras de arte, ¿es la copia una buena alternativa a la diáspora patrimonial?
Authors: Ruiz Romero Zara
Published: December 2023

El patrimonio cultural enfrenta en la actualidad distintas problemáticas relacionadas con su conservación, su posesión, así como el lugar en el que debería resguardarse. Estas disyuntivas pueden además conllevar una pérdida patrimonial en distintos sentidos: la obra no se encuentra en su lugar de procedencia, se ha destruido de manera intencionada, o ha desaparecido por efecto del expolio, el robo, o por cuestiones relacionadas con su preservación. Con el objetivo de paliar la sensación de vacío que la ausencia del patrimonio puede ocasionar, se reflexiona en este escrito sobre la utilización de reproducciones. Para ello, se muestran un conjunto de ejemplos en los que la réplica se integra en las exposiciones y espacios culturales, cumpliendo una serie de funciones de manera más o menos exitosa, aunque sin pretender la sustitución del “aura” del original.
De Palermo a Mazara del Vallo:
Authors: Amaro Martos Ismael
Published: December 2023

Ugone Papè di Valdina (1724-1791) acumuló un importante número de insignias y ornamentos sagrados en Palermo, antes de ser nombrado obispo de Mazara del Vallo (Trápani, Sicilia, Italia) en 1772, cargo que ocupó hasta el día de su muerte. Esta colección, junto a otros bienes, fue inventariada en el año de su partida, para después llevarla hasta su nueva jurisdicción. En este trabajo se estudian las piezas textiles enumeradas en el documento histórico, ordenadas por tipologías y colores litúrgicos, se analizan sus características técnicas y matéricas, se proponen distintas hipótesis sobre los estilos decorativos que pudieron definir estos bienes, se dan a conocer los tejedores, bordadores, galoneros y sastres que debieron realizar algunas de estas prendas, y se relacionan con su contexto y los datos biográficos hallados hasta la fecha.
Lugares de la muerte en la capital colombiana dentro del contexto de la violencia, siglos XX y XXI.
Authors: Bautista Santos Sandra Patricia
Published: December 2023

Partiendo de la hipótesis que el análisis de la producción artística es una estrategia eficaz para comprender el lugar imaginario que un asunto como la muerte puede ocupar dentro de las ciudades. Este artículo propone una reflexión acerca de algunas de las obras de artistas colombianos, como: Débora Arango, Alejandro Obregón, Beatriz González, Doris Salcedo, Óscar Muñoz, María Evelia Marmolejo, Ana Claudia Múnera y Clemencia Echeverri. Cuyas narrativas visuales, fueron creadas en torno a un lugar y circunstancias específicas, en este caso Bogotá como un escenario de muerte derivada por los problemas de violencia sociopolítica transcurridos durante los siglos XX y XXI. Estas propuestas artísticas configuran una mirada muy profunda, con fuerte matiz crítico, sobre las posibles causas y el impacto que estos hechos han provocado en la manera de percibir la ciudad.
