Published: June 2024

Background and aimsLaboratory performance as a relative concept needs repetitive benchmarking for continuous improvement of laboratory procedures and medical processes. Benchmarking as such establishes reference levels as a basis for improvements efforts for healthcare institutions along the diagnosis cycle, with the patient at its center. But while this concept seems to be generally acknowledged in laboratory medicine, a lack of practical implementation hinders progress at a global level. The aim of this study was to examine the utility of a specific combination of indicators and survey-based data collection approach, and to establish a global benchmarking dataset of laboratory performance for decision makers in healthcare institutions.MethodsThe survey consisted of 44 items relating to laboratory operations in general and three subscales identified in previous studies. A global sample of laboratories was approached by trained professionals. Results were analyzed with standard descriptive statistics and exploratory factor analysis. Dimensional reduction of specific items was performed using confirmatory factor analysis, resulting in individual laboratory scores for the three subscales of “Operational performance,” “Integrated clinical care performance,” and “Financial sustainability” for the high-level concept of laboratory performance.Results and conclusionsIn total, 920 laboratories from 55 countries across the globe participated in the survey, of which 401 were government hospital laboratories, 296 private hospital laboratories, and 223 commercial laboratories. Relevant results include the need for digitalization and automation along the diagnosis cycle. Formal quality management systems (ISO 9001, ISO 15189 etc.) need to be adapted more broadly to increase patient safety. Monitoring of key performance indicators (KPIs) relating to healthcare performance was generally low (in the range of 10–30% of laboratories overall), and as a particularly salient result, only 19% of laboratories monitored KPIs relating to speeding up diagnosis and treatment. Altogether, this benchmark elucidates current practice and has the potential to guide improvement efforts and standardization in quality &amp; safety for patients and employees alike as well as sustainability of healthcare systems around the globe.

BackgroundDue to hazardous working conditions, welders are more likely to be exposed to mild to severe eye issues during the welding process. Globally, this issue is a major contributor to vision loss and blindness. One of the most frequent causes of unilateral blindness in the globe is ocular injury.ObjectiveThis review aimed to assess the pooled prevalence of ocular protection practice and associated factors among welders in sub-Saharan Africa.MethodsDatabases including PubMed, Scopus, web of Science, Google Scholar, and the African Journals Online were systematically searched for relevant literature. The statistical analysis was performed using STATA data analysis software version 14, while Microsoft Excel was used for data abstraction. We checked publication bias using a funnel plot and Egger and Begg regression tests. A p-value &lt; 0.05 was considered significant, suggesting the presence of presence publication bias. The I2 statistics were used to assess heterogeneity between studies. The study's overall effect was evaluated using the random effects model.ResultsFrom retrieved 2,326 original studies, 17 studies were included in the final pooled prevalence analysis. The overall prevalence of ocular protection practice among small-scale welders in sub-Saharan Africa was 53.71% (95% CI: 42.54, 64.88). Having pre and in-service training [AOR: 4.97, 95% CI: (2.64, 9.36)], having work experience as a welder [AOR: 4.94, 95% CI: (3.24, 7.54)], and having a history of ocular injury [AOR: 2.99, 95% CI: (1.58, 5.66)] were significantly associated with the ocular protection practices.ConclusionsIn sub-Saharan African countries, the ocular protection practices among small-scale welders were low. Furthermore, the current meta-analysis found ocular protection practice to be significantly associated with on-the-job training, work experience of welders, and a history of ocular injury in the past year of small-scale welders in sub-Saharan Africa. This review will serve as baseline data for further studies to generate inputs for eye care providers and policymakers to improve good practice levels about ocular protection. Policies should be put in place to ensure all welders use proper personal–protective equipment, and receive regular health training.
Dual-Polarized Dipole Antenna with Wideband Stable Radiation Patterns Using Artificial Magnetic Conductor Reflector
Authors: Lin Xianjing , Mai Jielin , He Hongjun , Zhang Yao 
Published: June 2024

This paper presents a wideband dual-polarized dipole antenna structure operating at 1.7–3.8 GHz (76.4%). For a traditional 4G dipole antenna that covers the band 1.71–2.69 GHz, it is difficult to maintain the satisfactory impedance matching and normal stable radiation patterns within the 5G sub-6 GHz band 3.3–3.8 GHz, mainly due to the fixed antenna height no longer being a quarter-wavelength. To solve this, a connected-ring-shaped metasurface structure is proposed and deployed to operate as an artificial magnetic conductor (AMC). As a result, stable antenna radiation patterns are obtained within the whole band 1.7–3.8 GHz. For verification, this wideband dipole antenna using AMC is implemented and tested. The measured results show that the proposed antenna has an impedance bandwidth of 80.7% (1.7–4.0 GHz). It has an average measured in-band realized gain of 7.0±1.0 dBi and a stable 70±5 half power beam width (HPBW) within the 4G/5G-sub 6GHz bands 1.71–2.69 GHz and 3.3–3.8 GHz.
The Unfulfilled Dream of Grand Duchess Elizabeth Feodorovna: the Project of Russian Presence in the Church of the Holy Sepulchre (1912–1917)
Authors: Ковальская Е.Ю. 
Published: June 2024

Статья посвящена проекту получения Россией в собственность двух алтарей в храме Гроба Господня, чир позволило бы проводить на постоянной основе богослужения на славянском языке у главной христианской святыни. Инициатором проекта был отставной офицер Н.Н. Шедевр, человек с авантюрными наклонностями, некоторое время служивший при эфиопском императоре Менелике II. Н. Шедевр предлагал России поддержать Эфиопию в споре о возвращении нескольких часовен в храме Св. Гроба, которыми овладели копты. Была достигнута договоренность, что в случае успеха эфиопы передадут России две часовни. Нуждаясь в средствах на осуществление проекта и высоких покровителях, Н. Шедевр в 1912 г. обратился за помощью к вел. кн. Елизавете Федоровне. Они горячо поддержала эту идею и финансировала ее из личных средств, а также подключила к проекту императора Николая II, который также выделил значительную сумму на это начинание. Летом 1914 г. при эфиопском дворе готовилось посольство в Россию для официального оформления этих договоренностей, однако оно не состоялось из-за начавшейся Мировой войны. Несмотря на смерть Н. Шедевра в 1915 г., Елизавета Федоровна не отказалась от своих планов, и тема русского присутствия в храме Гроба Господня неоднократно поднималась на совещаниях ИППО и в дипломатических кругах в 1915–1917 гг. Февральская революция 1917 г. вывела Россию из этого проекта.
The article discusses Russia’s project to acquire ownership of two altars in the Church of the Holy Sepulchre, which would have allowed for permanent Slavic-language services at Christianity’s most significant shrine. The project was initiated by retired officer N.N. Shedevr, an adventurous man, who had briefly served for a period under Ethiopian Emperor Menelik II. N. Shedevr proposed that Russia support Ethiopia in a dispute over the return of several chapels in the Church of the Holy Sepulchre that had been seized by the Copts. An agreement was reached that, should the Ethiopians prevail, they would transfer two chapels to Russia. In need of funds and high-level patrons for the project. N. Shedevr in 1912 sought assistance from Grand Duchess Elizabeth Feodorovna. She enthusiastically endorsed the idea, funding it from her personal finances, and also involved Emperor Nicholas II, who contributed a substantial sum to the initiative. In the summer of 1914, the Ethiopian court was preparing to send envoys to Russia to formalize these agreements, but the trip was canceled due to the outbreak of World War I. Despite N. Shedevr’s death in 1915, Elizabeth Feodorovna did not abandon her plans, and the issue of Russian presence in the Church of the Holy Sepulchre was frequently discussed at Imperial Orthodox Palestine Society meetings and in diplomatic circles from 1915 to 1917. The February Revolution of 1917 resulted in Russia’s withdrawal from the project.

Abstract
The decomposition of Cu-Ethylenediaminetetraacetic Acid (Cu-EDTA) using a pulsed streamer discharge in contact with liquid is reported under various experimental conditions, and the efficacy of OH radicals is investigated. The change in Cu-EDTA concentration was characterized using high-performance liquid chromatography. H2O2, NO2
−, NO3
−, and O3 were detected using water inspection test kits and an UV-visual spectrophotometer. The OH yield was estimated using a colorimetric method with disodium terephthalate. The results revealed that approximately 70% of the Cu-EDTA decomposed with an energy efficiency of 15 mmol kWh−1 in the Ar discharge, whereas the decomposition rate and energy efficiency in the air discharge were 80% and 16 mmol kWh−1, respectively, within 60 min of treatment. The decomposition in Ar was primarily driven by the OH generated during discharge, whereas a combined effect of O3 and OH was observed during air discharge. The discharge-generated OH was the dominant species in Cu-EDTA decomposition in this study.

Expressive Imagine an art installation that transcends the static
canvas, transforming in real-time based on the collective emotional
pulse of the room. This isn’t a scene from science fiction – it’s the
groundbreaking reality of Expressive Canvas. This innovative artwork
harnesses the power of cutting-edge technology to create a truly
immersive experience, blurring the lines between art and audience.
At the heart of Expressive Canvas lies advanced emotion recognition
software. With an accuracy of approximately 63%, this sophisticated
system analyzes the subtle expressions on viewers’ faces, capturing the
nuances of joy, sadness, surprise, and everything in between. These
emotional cues are then translated into a mesmerizing dance of color,
light, and form. A collective sigh of contentment might bathe the scene
in warm hues, while a ripple of anxiety could send shivers of cool blues
across the canvas. Every laugh, tear, and flicker of emotion becomes a
co-creator, shaping the artwork in a perpetual metamorphosis.
Expressive Canvas isn’t just a spectacle; it’s a catalyst for profound
experiences. By witnessing the impact of their own emotions on the
artwork, viewers embark on a journey of self-discovery. They gain a
heightened awareness of their inner landscape, their feelings reflected
and amplified on the ever-changing canvas. As the collective mood paints
the scene, a sense of shared humanity emerges. Individual emotions
become interwoven, creating a vibrant tapestry that celebrates the
beautiful complexity of human experience.
This groundbreaking installation leverages the power of machine learning
and image processing to redefine the future of art. It is a living,
breathing entity – a conversation between audience and technology that
fosters deeper connections than ever before. Expressive Canvas is not
merely observed; it’s actively participated in, inviting viewers to
become co-creators in a world where art is a tool for emotional
exploration, social connection, and a gateway to a richer understanding
of ourselves and others.
Implementation of Floating-Point Arithmetic Coding using x86-64 AVX-256 Assembly Language
Authors: Gray Mike H. B. 
Published: June 2024

Bit manipulations, especially those executed on multiple strings in
parallel, e.g., on Intel® processors equipped with Advanced Vector
Extensions (AVX), can be a powerful way to speed up unoptimized
high-level sequentially executed code. A case in point is made for
floating-point arithmetic coding (FPAC), implemented herein as a
non-adaptive, lossless data compression algorithm using x86 AVX-256
stand-alone assembly language under 64-bit MASM assembler in Visual
Studio 2022. Apart from writing and reading bit strings to and from
file, FPAC can become fully vectorized and be improved in performance
(relative to unoptimized integer versions) by orders of magnitude by
blocking short sequences of symbols and bypassing interval
renormalization. For an alphabet size up to 53—the limiting case made
for 0.474MB Protein Data Bank entry 4HHB, referred to as oxygen
transport file (OTF)—it can also strongly outperform a commercially
available, unoptimized C++ Huffman encoder by over a factor of 10 and
beat the decoder by roughly a factor of 2. Disadvantageous but
necessary to this prescription of vectorizations is an additional
compressed storage requirement of the length of the codeword (this
binary integer is to encode a block of 5 symbols) in addition to the
codeword itself; for size-5 blocks, this compromises the compression
efficiency as follows: the average number of bits per symbol required to
compress the input message is demonstrated to lie in the interval
[H(S) + b, H(S) + 0.4 + b], where b = 1.0 for single-precision
floating-point arithmetic coding (SPFPAC), b = 1.2 for a slower but more
practical double-precision counterpart (DPFPAC), and H(S) is the Shannon
entropy of symbol frequencies.

Vegetables are an important commodity, whose prices contribute to the inflation rate in some regions of Indonesia. Inflation and deflation are inseparable from the type of food and vegetable groups because the majority of the population have jobs as vegetable farmers. Selo Boyolali is a vegetable-producing region, but currently can not meet the needs of its own region. Supply of vegetables began to decrease due to pest and vegetable turnover into tobacco. If the delivery of vegetables is hampered there will be a scarcity of vegetables that lead to price increases. The length of the distribution channel has a negative impact, namely the price of commodities set by the middlemen or traders who distribute vegetables from the producers. So sometimes local farmers do not have bargaining power on vegetable pricing. This study aims to analyze the pattern of price formation and vegetable distribution in Boyolali. The analytical framework used in this research is supply chain management framework. The method used in this research is quantitative and qualitative indepth interview.

الامبراطور شارلمان والكنيسة (التحالف السياسي الديني)
Authors: عبدالحميد فرج آدم إيمان 
Published: June 2024

لقد جاء هذا البحث تحت عنوان: الإمبراطور شارلمان والكنيسة (التحالف السياسي الديني).
ولقد احتوت المقدمة على تبيان بسيط لما تطرق إليه البحث إلى جانب أهمية الموضوع وأهدافه.
وتناول البحث: (الباباهادريان والمشكلة اللمباردية)، حيث جاء فيه علاقة الإمبراطور شارلمان بالباباهادريان وموقفه من الصراع بين البابا واللمبارديين، لاسيما في إيطاليا والحروب التي كانت تشتعل بين الطرفين من حينٍ لآخر، كما أنّ شارلمان في بداية هذا الصراع كان يقف على مسافة واحدة بين الطرفين، إلا أنه ومع استمرار هذا الصراع ولأجل المصالح التي جمعته مع الباباهادريان أخذ يميل لمناصرة هذا البابا ضد اللمبارديين، وصولاً إلى منحه ما عُرف بـ "هبة البابا" عام 774م، والتي أقرّ فيها شارلمان معظم إيطاليا تكون للباباهادريان، إلا أنّ انشغال شارلمان بحروبه ضد السكسون جعله يبتعد عن ولائه للباباهادريان، إلى أن جاء عام 777م، حيث إنه في هذه السنة رُزق شارلمان بولد تولى الباباهادريان تعميده، فكانت هذه الخطوة فرصة طيبة لعودة التحالفات من جديد.
كما أشار إلى (تحالف الملك شارلمان والبابا هادريان ضد البافار والفريزيين)، خُصّ هذا المبحث بتحالف شارلمان وهادريان ضد عدو آخر، وهم البافار، ولكن الأمر مختلف نوعًا ما عن اللمبارديين، فاللمبارديين كانوا في الأصل أعداءً للباباهادريان فقط، ولكن البافار أعداءً للطرفين أي شارلمان وهادريان؛ لأنّ البافاريين كانوا قد أدّوا قسم الولاء للكارولنجيين زمن بيبين القصير ولأبنائه من بعده، كما إنّ البابا ألزمه بالطاعة له وللكنيسة وإلا سوف يوقع عليه عقوبة الحرمان إضافة إلى الصراع مع الفريزيين وإدخالهم في الديانة المسيحية.
وجاء في الختام (البابا ليون الثالث "الحليف الجديد")، كان البابا ليون الثالث منذ البداية قد حاز على رضى شارلمان، لذلك آثرتُ أن أطلق عليه في هذا المبحث بالحليف الجديد، بالرغم من عدم قبوله من قبل باقي الأساقفة ورجال الدين؛ لأنه لم يكن من النبلاء، بل من عامة الناس، لذلك فقد تعرض لعدة محاولات لإزاحته عن الكرسي الباباوي، لكن شارلمان كان يدافع عنه بقوة، فقد كان ليون الثالث سببًا رئيسيًا في تتويجه امبراطورًا، وذلك عام 800م للميلاد وتسمية الامبراطورية الرومانية المقدسة بزعامة شارلمان وبمباركة من البابا ليون الثالث، أصبح الامبراطور شارلمان هو الزعيم الروحي للرومان.
