The immune and hematopoietic systems in the human body depend on the spleen. The understanding of anatomical and morphological variations of the spleen and its arterial vascular segments (AVS) is crucial for performing whole or partial splenectomy in the treatment of splenomegaly and splenic rupture. The aim of this study was to compare the anatomical differences in the spleen and its AVS in Thai cadavers of both sexes. This cadaveric study was performed on 77 cadaveric spleens (males = 38 and females = 39) from the Gross Anatomy Laboratory at the Department of Anatomy, Faculty of Medicine Siriraj Hospital, Mahidol University. The average morphological measures of the observed spleens were 9.11±1.40 cm in length, 6.57±1.46 cm in width, 3.11±0.67 cm in thickness in male cadavers, and 8.77±1.87 cm in length, 5.91±1.35 cm in width, and 2.90±0.78 cm in thickness in female cadavers. The variations in spleen form were 7.79% oval, 16.88% tetrahedral, 28.57% triangular, and 46.75% wedge. The mean splenic hilum length was 5.14±1.10 cm in males and 5.12±1.22 cm in females. The mean lobar branch to hilum distance was 2.26±0.98 cm in males and 2.29±1.05 cm in females. Females were more likely than males to have two lobar arteries. Three lobar arteries, however, were more prevalent in males. The occurrence of accessory spleens was 2.63% for males and 7.50% for females. According to the data, there were significant differences in the number of lobar arteries and spleen size between male and female Thai cadavers.

Anatomical variants of the venous central system are very infrequent; nevertheless, it is useful to be aware of them in order to avoid complications during common procedures. The purpose of the present study is to describe an anatomical variant of the Right Internal Jugular Vein (RIJV), and to investigate the frequency of this variant reported in the current literature. Authors present an anatomical variant of RIJV, found during the dissection of an adult male cadaver, previously fixed in a formaldehyde-based solution, who was voluntarily donated to the Faculty of Medicine of Universidad de la República in Montevideo, Uruguay. The cadaveric material was used taking into account the Helsinki Declaration regarding prior live donation and informed consent. A photographic record and a bibliographic search in electronic bases were carried out in order to discover the frequency with which this variant occurs. It was described as an isolated duplicated RIJV, which had its origin at the level of the right jugular foramen, and had its division next to the thyroid cartilage after a path of 6.5 cm into two branches (anteromedial and posterolateral) that ended separately, and were 7.2 cm and 5.4 cm in length, respectively. The relations with near structures such as the accessory nerve and the omohyoid muscle were also described and compared with the literature reviewed.

The facial artery undergoes multiple anatomic variations that condition the territory that vascularizes to the facial level. During the dissection of several pieces, we find a curious anatomic alteration in which the transverse facial artery is the one that replaces the facial artery because it disappears at the level of the submandibular gland. This anatomic variance can help to improve the knowledge of the vascularization of this area and be helpful in the different surgical or aesthetic processes in the facial region, and doing so minimizes the damages that can be caused in the anatomical surfaces treated. This is why in the planning of the treatment it would be always useful to know the path of the main vessels and nerves to avoid their possible injury and, in this case, we recommend the use of means such as ultrasound.

Published: February 2024

The hand is often compromised by scars or potentially necrotic wounds. Complete loss of index finger will result in impairment of 20% of hand and 11% of whole-person. One of the most influential factors in consideration of tissue loss are defect size, site, depth, and orientation. In our case study, a 16-year-old male presented with sensations of tingling and pain in his finger subsequent to an accidental laceration. Examination revealed a necrotic wound located on the distal phalanx of the index finger, accompanied by mild atrophy and discoloration. Subsequently, the patient underwent graft harvesting from the right chest wall flap, followed by primary closure of the donor site on the right chest wall. Upon a three-month follow-up, the patient expressed satisfaction, demonstrating proficient daily activities despite the injury being localized to the left hand. Utilizing a chest wall flap is less prevalent than employing regional or free flaps. Anterior chest wall flaps are specifically crafted on the anterolateral chest wall or within the infraclavicular region. The choice of a chest wall flap was determined to offer a less cumbersome graft and aligns with the patient's preference. The main goal of soft tissue reconstruction is to restore functionality, encompassing tasks such as exploration, sensation, and manipulation of objects, while simultaneously preserving the original length. Nonetheless, achieving this goal remains a complex challenge.

Influence of Different Post Porosification Cleaning Steps on the Parameters of Porous Silicon Layer Stack

Published: February 2024

To grow a defect-free epitaxial silicon wafer (EpiWafer) on a reorganized porous silicon layer stack, the surface must be closed, smooth and particle-free. A post-porosification cleaning step prior to reorganization should significantly reduce the density of (metallic) particles on the surface. In this paper we systematically investigate the influence of different post-porosification cleaning steps on the porous layer stack. The different cleaning steps have no significant effect on the layer thicknesses. On the other hand, the porosities change after the different cleaning steps. The change in porosity correlates very well with the oxidizing effect of the solution used: SC-1 cleaning has the strongest oxidizing effect, followed by ozone cleaning, piranha cleaning and HCl cleaning. A single HF dip has the smallest effect on porosity, showing the small influence of the native silicon oxide layer formed by aging on porosity. Except for the SC-1 cleaning, the other cleanings show no significant change in the Raman peak shift and therefore in stress compared to the as-etched sample. For the SC-1 cleaning, the increase in Raman peak shift and thus stress correlates well with the increase in porosity. After a reorganization step at 1120°C, it is observed that a higher porosity of the low porosity layer in the stack leads to larger pores.
Multimode multiple scattering in disordered systems of spherical scatterers
Authors: Pinfield Valerie
Published: February 2024

We will consider the propagation of ultrasound in nano/microparticle suspensions consisting of disordered (randomly distributed) solid particles in a viscous liquid or other soft viscoelastic material. Understanding the complex wave propagation in such systems is important, both from the point of view of characterising soft materials – for biological tissues, or for industrial process monitoring e.g. in pharma and food – and for the design of metamaterials where enhanced absorption may be desirable – for example for stealth coatings. An important and interesting characteristic of these systems is the existence of two wavenumbers of very different magnitudes in the continuous phase – for the compressional and shear modes. For typical liquids at MHz frequencies, and with colloidal particles, the dimensionless compressional wavenumber (based on particle size) may be small whereas the dimensionless shear wavenumber can range from small to large and is always much larger than the dimensionless compressional wavenumber. In addition, we have another length scale that affects the multiple scattering, i.e. the interparticle separation; its effects are usually accounted for through the concentration or number density but it may be helpful to consider these effects in terms of additional dimensionless wavenumbers relating to the interparticle distance.
Recently, a new formulation for the effective wavenumber arising from multiple scattering in a multi-mode media was published (Luppe, Conoir Valier-Brasier, Wave Motion 115 (2022) 103082). In this presentation, we will show analytical asymptotic results obtained from the model at long compressional wavelength (low frequency), but arbitrary shear wavelength for these soft media, highlighting the dominant wave-conversion and correlation contributions. We will show numerical results to validate the approximations made for this system and compare with experimental data. Although it is common to consider that structure has minimal effect at long wavelength, in these dual-wave-mode systems the particle correlations are seen to have a significant effect because of the influence of the small shear wavelength.

A total of 289 goats’ nasal swabs were collected from March to May 2023 to determine the prevalence of Pasteurella multocida in goats raised on medium-scale farms in Can Tho city. There were 143 samples representing 49.48% positive for Pasteurella multocida. Of 143 positive samples, 64 strains were selected to examine the antimicrobial susceptibility using the disk diffusion method. The results showed that those strains were still sensitive to 6/7 examined antibiotics, especially doxycycline (100%); however, they were highly resistant to ampicillin (53.13%). There were 9 phenotypes of antibiotic resistance (60.94%), with the most common patterns of ampicillin and ampicillin + amoxicillin/clavulanic acid (23.44%).By using PCR assay to detect antibiotic resistance genes, the results revealed that sulII gene was the most frequent detection (67.19%). A total of 11 resistance genotypes detected in 54 strains accounted for 84.38%, and the pattern of aadB + sulII was the most common genotype accounting for 23.44%. Therefore, the prevalence and antimicrobial susceptibility of P. multocida in goats should be controlled to protect their health and prevent spreading in husbandry environments.

Published: February 2024

To address the problem of low localization accuracy in the node localization algorithms of wireless sensor networks (WSN) based on received signal strength indication (RSSI) ranging, a WSN node localization algorithm based on ranging optimization and graph optimization is proposed. In terms of RSSI ranging, the outliers are removed using the Grubbs method, and the data are processed using a moving average smoothing-Gaussian hybrid filter to establish a Bessel function ranging model to reduce the ranging error; in terms of node localization, the signal strength data are employed to construct a distance cost term, a cost function model is built based on these cost terms, and graph optimization is adopted to minimize this function. Then, the node position is estimated to minimize the overall observation error. Simulation results indicate that the proposed algorithm has higher ranging and localization accuracy than existing ranging and localization algorithms, and it can meet the requirements of node localization in large-scale WSN.

Published: February 2024

The expansion of 5G and Internet of Things has laid a good foundation for the in-depth research of Internet of vehicles. Low frequency resources are scarce, and Internet of vehicles communication requires extremely high communication rate. Millimeter wave can meet the above two requirements, but its characteristics and the complicated communication conditions of Internet of vehicles make it difficult to combine the two. Overcoming these problems and making beam tracking accurate and steady is a major challenge at present. In this paper, a new extended Kalman filter tracking algorithm is proposed for mmWave V2I scenarios. On the basis of the original algorithm, a threshold prediction update mechanism is added. A new scheme is adopted, which takes position and velocity as tracking variables, and the tracking model is derived for the first time in MIMO 3D scenarios based on this scheme. The model considers the three-dimensional road conditions, including the vehicle deflection motion and the millimeter wave link blocked by large vehicles, which is more suitable for practical application scenarios. The simulation results reveal that the position and velocity tracking scheme is superior to the angle and gain tracking scheme, and the tracking error of the proposed algorithm is lower than that of the algorithms using similar state models. Based on the three-dimensional scene, it considers more realistic situations, and is more consistent with the kinematic characteristics of the vehicle and has more practical significance.

 
Robust Zero-Watermarking by Circular Features and 1-D NRDPWT Transformation
Authors: Hsiu-Chi Tseng Hsiu-Chi Tseng , Hsiu-Chi Tseng King-Chu Hung
Published: February 2024

This paper introduces a secure and robust zero-watermarking framework that leverages the advantages of zero-watermarking, ensuring non-destructive modification of original images and unlimited capacity. The proposed method enables robust watermark embedding while preserving the original image. It employs a novel feature extraction approach using circular areas based on image radius, enhancing feature resilience. Additionally, applying one-dimensional non-recursive discrete periodized wavelet transform (1-D NRDPWT) converts feature values into phi, contributing to enhanced stability and robustness. Enhanced security is achieved through the use of Shuffle and Pseudo-Random Number Generator (PRNG). Experimental results, evaluated using metrics such as Bit Error Rate (BER) and Normalized Correlation (NC), validate the exceptional performance of this watermarking technique. These findings underscore the framework’s robustness, security, reliability, and integrity against both general and geometric noise attacks, making it a secure and robust solution for modern digital image copyright protection.

Applying Compressed Sensing (CS) technology to robot vision image transmission, an effective method for image reconstruction in robot imaging is proposed to improve the accuracy of reconstruction. Reconstructing images using a mixed sparse representation of DCT and circularly symmetric contour wave transform, the basic algorithm used is the Smoothed Projection Landweber (SPL) algorithm, which optimizes the coefficients under different sparse transformations by incorporating hard thresholding and binary thresholding methods for different sparse bases during iterations. The experiment shows that compared with single sparse base image reconstruction, the proposed reconstruction method has improved reconstruction accuracy.

Guiding industrial robots to complete grasping tasks through machine vision is an important part of achieving autonomous robot operation. This article explores the control method of industrial robots under 3D vision, focusing on the feature that two-dimensional vision can only perform color and pose recognition but lacks depth recognition. Firstly, a high-precision point cloud registration calibration matrix solution method is proposed. Then, an improved recognition model is designed to address the issue of how vision guides robots to grasp and detect. This model integrates feature extraction and object detection modules, and describes the parameters of each module. Finally, the effectiveness of the proposed method is verified in the assembly scene of gas instruments. Finally, experimental results show that, the method proposed in this article can limit the grasping accuracy to within 2 millimeters in guiding robots to grasp detection scenes, achieving the expected effect.

 
臺灣傳統紙媒數位轉型的另一種可能──以《今周刊》為例
Authors: 廖怡景 廖怡景
Published: February 2024

二十一世紀的媒體產業並非處於一個太平盛世，數位化已衝擊傳統媒體生態。本研究以強調紙本價值並採取非主流數位轉型模式的傳統媒體組織《今周刊》為例，以Dąbrowska et al.（2022）三層次的數位轉型模型，分別從鉅觀至微觀角度分析生態、組織、個人等數位轉型的三面向，探究臺灣傳統紙媒在主流數位轉型模式之外的另一可能。本研究發現：一、傳統媒體數位轉型的不同模式，例如：「平網並進」、「紙本先行」模式，和「數位優先」、「中央廚房制」有明顯的差異；二、華人社會企業組織常見「家父長制領導」風格在《今周刊》數位轉型過程中扮演重要角色且有極大的影響；三、《今周刊》強調「紙本優先」的「雙廚房制」模式，重新提醒「紙本媒體」的定位和價值。

 

The media industry of the 21st century is not in a period of peace and prosperity. Digitization has already impacted the traditional media ecosystem. This case study focuses on Business Today magazine, a traditional media company that values the importance of print media while adopting an unconventional approach to digital transformation. Using Dąbrowska et al.’s three-level digital transformation model, the study analyzes the three dimensions of digital transformation—ecology, organization, and individual—from a macro to a micro perspective. The study explores an alternative possibility for traditional print media in Taiwan beyond the Western mainstream digital transformation models. The findings of this study are as follows: First, there are significant differences among the various models of digital transformation for traditional media. The “simultaneous development of digital and print media” and “print-first” strategies are distinctly different from the strategies of “digital-first” and “central kitchen system.” Second, the common “paternalistic leadership” organizational style prevalent in Chinese society plays a crucial role and has a significant impact on the digital transformation process of Business Today magazine. Third, Business Today magazine emphasizes the “print-first” and “dual-kitchen” model, reminding people once again of the positioning and value of “print media.”

 
社群參與下的記者會傳播情境：記者專業實踐的困境與因應策略

Published: February 2024

數位時代社群平臺直播伴隨網友的即時評論，不但縮短消息來源與閱聽人的距離，也改變記者與消息來源的互動形式。研究以Goffman之戲劇理論和Foucault的圓形監獄全景敞視權力與規訓概念，來檢視2020年疫情指揮中心直播記者會的傳播情境。以深度訪談法研究後發現，直播傳播情境具記者、網友、消息來源三方權力競逐的特質，記者會的前臺以各式道具凸顯政府防疫成果，記者成為被觀看的對象，提出尖銳問題則易被網友攻擊或「出征」，使記者產生被規訓的節制行為，採取消極避禍策略；在後臺則出現外人侵入記者與官員互動的封閉對話群組，兩造的對話被擴散至社群媒體，使記者承受網路騷擾的壓力。處於前臺與後臺雙重壓力的記者，仍在困境中以不同策略實踐媒體問責。

 

In this digital age, live streaming on social media platforms, accompanied by real-time comments from netizens, not only shortens the distance between the news source and the audience but also changes the way reporters interact with their sources. This study employs Goffman’s dramaturgical theory and Foucault’s views on the panopticon and disciplinary power to examine the communicative context of the live broadcasts of the 2020 Central Epidemic Command Center press conferences during the COVID-19 pandemic. Using the in-depth interview method, the researcher found that the live broadcast communication creates a three-party power competition situation involving reporters, netizens, and news sources. In the front stage of the press conference, various props are used to highlight the outcomes of epidemic prevention. Reporters become the observed subjects, and those who raise sharp questions risk facing attacks by netizens. This dynamic caused the reporters to exert self-restrain, be “disciplined,” and adopt passive ways to avoid being embroiled in awkward situations. In the back stage, closed dialogues between reporters and officials are being leaked to social media platforms by external intrusive forces, thus exposing the reporters to the pressure of online harassment. Under dual pressures from both the front stage and the backstage, the reporters continue to navigate the dilemma by implementing various strategies to practice media accountability.

 
做自己或成為一分子？社會網絡對消費者效用的影響：代理人基模型之模擬應用

本文探討社會網絡對消費者效用的影響，以代理人基模擬消費者於不同網絡型態的互動，重構Jager（2000）的模型並使用二維的效用函數。決策時間代表涉入程度，刻畫所有消費情境。模擬不同型態的社會網絡、密度、認知類型、總人數對個別消費效用的影響。並將效用函數拆解成個人與社會部份以捕捉影響主因。結果表明，任何社會網絡中，網絡愈疏散，消費者所獲得的效用愈高，原因為社會部份的效用稀釋減少；社群影響力下降，非純粹個人效用提升。檢視市場參與人數與社會網絡密度對消費者效用的影響後發現，若消費者身處適切的社會網絡，消費者效用提升。意即，較多的消費者於較疏散的網絡或較少的消費者於較密集的網絡，這二種社群環境對新進廠商相對有利，既存廠商優勢不明顯。

 

This study aims to examine the effect of social networks on consumer utility. An agent-based model was employed to simulate the interaction among consumers in different social network types. Jager’s (2000) agent-based model was reconstructed, and a two-dimensional utility function was introduced, considering decision-making time (product involvement) and incorporating all types of consumption scenarios. The goal was to simulate the impact of different types of social networks, social network densities, consumer cognitive types, and the total number of consumers on individual consumer utility. The utility function was decomposed into individual and social components to identify the primary factors influencing consumer utility. Research results indicate that in any social network, as the network becomes more dispersed, consumer utility increases. The reason for this is that the decline in social influence causes the social aspect of utility to be diluted and reduced, rather than a pure increase in individual utility. After examining the impact of the number of market participants and the density of social networks on consumer utility, it was found that if consumers are in an appropriate social network, consumer utility increases. This refers to situations where there are more consumers in a dispersed network or fewer consumers in a dense network. In these two types of social network environments, it is relatively advantageous for new entrants, but this advantage is not as evident for existing vendors.

Published: February 2024

The requirement of the shelter is essential for the sustenance of the dynamism of livelihood of human being, and it lead to urbanization. The urbanization results in concentration of human population in a smaller area, densify the construction of buildings for living and other civic purposes and other constructions to fulfill the needs of the human being such as, water supply, drainage system, roads, power generation units and many more. The construction activities of all these facilities impacts negatively on the environment. The environmental risk is the probability and consequence of an undesirable impact due to the human interventions in natural processes. The overall scale of construction activities are extremely high and the same is its impact on various elements of environment. In the presented study the four elements of environment, i.e. human health, general atmosphere, ecology and society, on which the impact takes place due to building construction activities are taken into consideration. A total of nine factors and the forty sources are considered for finding out their ranking, with the help of questionnaire survey, in which 102 construction professionals participated. The five point Likert scale is used for probability and impact and analyzed by using the weighted score approach. The outcome of the analysis gives the risk factors and their sources for four elements, which have the highest probability and the impact of occurrence. The ranking of the risks perceived are obtained through analysis.

Paddy is the second crop where huge amounts of chemicals are used for production, majorly for disease control. To avoid excess use of chemicals in the rice fields and also to find the best alternative solution to fungicides for sheath blight disease caused by Rhizoctonia solani, research was carried out by using various bioagents, plant extracts and synthetic bio-polymers. Prior to the field experiments, in vitro studies were carried out to check the efficacy of various bio agents and plant extracts by using dual culture and poisoned food techniques, respectively. Trichoderma harzianum showed the highest mycelial growth inhibition (60.37%), followed by Pseudomonas fluorescens (54.4%), and the least effective was showed by T. asperellum (37.44%). The field experiments were carried out in Kharif 2019-20 and 2020-21, to test the fruitfulness of in vitro studies along with some biopolymers. In Kharif 2019-20 out of all the treatments, effective treatment with least mean disease severity was observed in chitosan (12.50%) and nano silicon (14.79%) application when compared to the fungicide hexaconazole 5 EC (13.89%) which was used as a positive control and the least effective treatment was observed in seaweed extract (18.81%), followed by T. viride (19.0%) whereas, the untreated control showed 28.73% of disease severity. In Kharif 2020-21 chitosan (18.77%) and nano silicon (23.95%) treatments were effective when compared to the hexaconazole 5 EC (23.21%) and highest disease severity was observed in seaweed extract (37.0 %), followed by T. viride (34.81%), whereas the untreated control showed 51.6 % of mean disease severity.

Este estudo investiga o estágio de desenvolvimento das pesquisas em universidades brasileiras, focalizando na transferência de tecnologia e Vitrines Tecnológicas (VTs). Utilizando uma metodologia indutiva baseada em pesquisa bibliográfica, a análise abrange múltiplas fontes de evidências, como artigos em revistas indexadas. Embora as VTs incorporem diversos critérios, como contatos de agências de inovação e resumos de tecnologias, há uma lacuna na adoção generalizada do Nível de Maturidade Tecnológica (TRL). Para otimizar sua implementação, as universidades precisam investir na conscientização sobre sua importância, o que promoverá uma compreensão mais ampla das tecnologias desenvolvidas e fomentará maior transparência e engajamento com a sociedade. Conclui-se que estratégias que facilitam o acesso e a atualização das informações sobre tecnologias promovem não apenas a interação com a comunidade, mas também estimulam a colaboração e o progresso tecnológico, além de cultivar uma cultura empreendedora que incentiva o surgimento de startups e spin-offs.
