Abstract
Background
Dynamic hip screws (DHS) and proximal femoral nail anti-rotation (PFNA) were recommended for basicervical femoral neck fracture (BFNF), however, with high rate of postoperative femoral neck shortening. The proximal femoral bionic nail (PFBN) was designed to decrease the postoperative complications associated with DHS and PFNA. The aim of this study is to compare the biomechanical characters of DHS, PFNA, and PFBN for fixation of BFNF.

Methods
Using finite element analysis, we created a three-dimensional model of the BFNF for this investigation. The PFBN group, the PFNA group and the DHS + DS group were our three test groups. For each fracture group, the von Mises stress and displacements of the femur and internal fixation components were measured under 2100 N axial loads.

Results
The PFBN group demonstrated the lowest stress on the implants, significantly lower than the PFNA and DHS + DS groups. In terms of stress on the implants, the PFBN group exhibited the best performance, with the lowest stress concentration at 112.0 MPa, followed by the PFNA group at 124.8 MPa and the DHS + DS group at 149.8 MPa. The PFBA group demonstrated the smallest displacement at the fracture interface, measuring 0.21 mm, coupled with a fracture interface pressure of 17.41 MPa, signifying excellent stability.

Conclusions
Compared with DHS and PFNA, PFBN has advantages in stress distribution and biological stability. We believe the concept of triangle fixation will be helpful to reduce femoral neck shortening associated with DHS and PFNA and thus improve the prognosis of BFNF.

Abstract
Background
Data on hyperglycemia and glucose variability in relation to diabetes mellitus, either known or unknown in ICU-setting in COVID-19, are scarce. We prospectively studied daily glucose variables and mortality in strata of diabetes mellitus and glycosylated hemoglobin among mechanically ventilated COVID-19 patients.

Methods
We used linear-mixed effect models in mechanically ventilated COVID-19 patients to investigate mean and maximum difference in glucose concentration per day over time. We compared ICU survivors and non-survivors and tested for effect-modification by pandemic wave 1 and 2, diabetes mellitus, and admission HbA1c.

Results
Among 232 mechanically ventilated COVID-19 patients, 21.1% had known diabetes mellitus, whereas 16.9% in wave 2 had unknown diabetes mellitus. Non-survivors had higher mean glucose concentrations (ß 0.62 mmol/l; 95%CI 0.20–1.06; ß 11.2 mg/dl; 95% CI 3.6–19.1; P = 0.004) and higher maximum differences in glucose concentrations per day (ß 0.85 mmol/l; 95%CI 0.37–1.33; ß 15.3; 95%CI 6.7–23.9; P = 0.001). Effect modification by wave, history of diabetes mellitus and admission HbA1c in associations between glucose and survival was not present. Effect of higher mean glucose concentrations was modified by pandemic wave (wave 1 (ß 0.74; 95% CI 0.24–1.23 mmol/l) ; (ß 13.3; 95%CI 4.3–22.1 mg/dl)) vs. (wave 2 (ß 0.37 (95%CI 0.25–0.98) mmol/l) (ß 6.7 (95% ci 4.5–17.6) mg/dl)).

Conclusions
Hyperglycemia and glucose variability are associated with mortality in mechanically ventilated COVID-19 patients irrespective of the presence of diabetes mellitus.
Chest wall abscess and costochondritis due to Salmonella enterica serotype Choleraesuis: a case report
Authors: Mokraoui Nassim R. , Ganim Rose , Paez Armando 
Published: December 2023

Abstract
Background
Salmonella enterica serotype Choleraesuis infections usually cause self-limited gastrointestinal diseases. Extra-abdominal infections are often secondary to bacteremia in immunocompromised individuals and are relatively rare in immunocompetent hosts.

Case presentation
A 65-year-old Caucasian female initially presented to the thoracic surgery clinic due to a poorly healing wound on her chest. Her condition started after a mechanical fall hitting her chest with interval development of a tender lump that later spontaneously drained. A chest computed tomography scan with intravenous contrast demonstrated an abnormal infiltration with small foci of fluid and air consistent with a small abscess anterior to the left seventh costal cartilage. Aspirate culture of the abscess grew S. enterica serotype Choleraesuis susceptible to ampicillin and trimethoprim/sulfamethoxazole. The patient had no prior history of signs or symptoms of gastrointestinal infection. Blood cultures were negative. With a background of penicillin allergy, she was treated with trimethoprim/sulfamethoxazole, and later with ceftriaxone due to persistent drainage of the wound. Follow-up chest computed tomography scan with intravenous (IV) contrast showed continued abnormal findings previously seen in the computed tomography scan with the appearance of a sinus tract. The patient subsequently underwent surgical debridement and partial resection of the left seventh costochondral cartilage and excision of the fistula. She had an uneventful recovery and complete resolution of her condition.

Conclusion
We report a rare case of chest wall abscess with associated costochondritis due to S. enterica serotype Choleraesuis in a patient with no evidence of immunodeficiency nor history of bacteremia. Extraintestinal infections due to Salmonella without documented bacteremia have been previously reported in the literature. History of local trauma to the affected area might contribute to the seeding of infection. Diagnosis is often accomplished by clinical evaluation and culture of the affected area. Treatment often involves targeted antibiotic therapy but may require surgical intervention to achieve source control and cure.
Lightweight target speaker separation network based on joint training

Published: December 2023

AbstractTarget speaker separation aims to separate the speech components of the target speaker from mixed speech and remove extraneous components such as noise. In recent years, deep learning-based speech separation methods have made significant breakthroughs and have gradually become mainstream. However, these existing methods generally face problems with system latency and performance upper limits due to the large model size. To solve these problems, this paper proposes improvements in the network structure and training methods to enhance the model’s performance. A lightweight target speaker separation network based on long-short-term memory (LSTM) is proposed, which can reduce the model size and computational delay while maintaining the separation performance. Based on this, a target speaker separation method based on joint training is proposed to achieve the overall training and optimization of the target speaker separation system. Joint loss functions based on speaker registration and speaker separation are proposed for joint training of the network to further improve the system’s performance. The experimental results show that the lightweight target speaker separation network proposed in this paper has better performance while being lightweight, and joint training of the target speaker separation network with our proposed loss function can further improve the separation performance of the original model.

Abstract
The Sanxingdui site (4.4–2.9 ka B.P.) in southwestern China is considered one of the most significant archaeological discoveries of the twentieth century, which contains numerous codes for interpreting the origin and development of the Yangtze River civilization. Remains found in Sanxingdui burial pits are keys to deciphering some of these codes. From the characters of the charcoal fragments, ashes and jades in the Sanxingdui buried pits, at the same time, comprehensively analyzing archaeological evidence and previous research results, we speculate that the temperature of ancient Shu people burning sacrifices could be 600–800 ℃. However, the values of magnetic properties and chroma of soils near the ash layers in the pits, and Guanghan Clay near the pits, do not show obvious changes caused by such high-temperature annealing. Combined with the geographical location of the pits and the accumulation characteristics of ash layers and artifacts in the pits, we consider that the Sanxingdui burial pits were not trash pits but sacrificial pits, and they were used for burying sacrifice after burning sacrifice. Although the ritual of burying sacrifice after burning sacrifice dates back to the Longshan period (4.3–4.0 ka B.P.) in China’s Central Plain, the Sanxingdui sacrificial pits, which began to occur in the late Shang Dynasty (~ 3.0 ka B.P.) with such a large scale, and the sacrifices unearthed from the pits, are unique. So, we believe that although influenced by the Central Plain culture, the ancient Shu people in the late Shang Dynasty have unique characteristics of culture and religion.
Impaired Growth Plate Maturation in XLH Is due to Both Excess FGF23 and Decreased 1,25-Dihydroxyvitamin D Signaling

Published: December 2023

Abstract
X-linked hypophosphatemia (XLH) is the most common form of hereditary hypophosphatemic rickets. The genetic basis for XLH is loss of function mutations in the phosphate-regulating endopeptidase X-linked (PHEX), which leads to increased circulating fibroblast growth factor 23 (FGF23). This increase in FGF23 impairs activation of vitamin D and attenuates renal phosphate reabsorption, leading to rickets. Previous studies have demonstrated that ablating FGF23 in the Hyp mouse model of XLH leads to hyperphosphatemia, high levels of 1,25-dihydroxyvitamin D, and is not associated with the development of rickets. Studies were undertaken to define a role for the increase in 1,25-dihydroxyvitamin D levels in the prevention of rickets in Hyp mice lacking FGF23. These mice were mated to mice lacking Cyp27b1, the enzyme responsible for activating vitamin D metabolites, to generate Hyp mice lacking both FGF23 and 1,25-dihydroxyvitamin D (FCH mice). Mice were fed a special diet to maintain normal mineral ion homeostasis. Despite normal mineral ions, Hyp mice lacking both FGF23 and Cyp27b1 developed rickets, characterized by an interrupted, expanded hypertrophic chondrocyte layer and impaired hypertrophic chondrocyte apoptosis. This phenotype was prevented when mice were treated with 1,25-dihydroxyvitamin D from day 2 until sacrifice on day 30. Interestingly, mice lacking FGF23 and Cyp27b1 without the PHEX mutation did not exhibit rickets. These findings define an essential PHEX-dependent, FGF23-independent role for 1,25-dihydroxyvitamin D in XLH and have important therapeutic implications for the treatment of this genetic disorder.
Venous adventitial cystic disease is a very rare disease that can cause deep vein thrombosis: A case report
Authors: Bae Miju , Huh Up , Lee Chung Won , Kim Jong Won 
Published: December 2023

BACKGROUND
Venous adventitial cystic disease (VACD) is a rare disease characterized by cysts, filled with a gelatinous mucous substance similar to joint fluid, in the adventitia of blood vessels adjacent to the joints. It is often misdiagnosed as deep vein thrombosis (DVT), femoral varices, venous tumors, or lymphadenopathy.
CASE SUMMARY
A 69-year-old woman visited our hospital with a complaint of swelling in the right lower extremity. The patient was diagnosed with DVT and prescribed apixaban at an outpatient clinic. After 3 wk, the patient was hospitalized again because of sudden swelling in the right lower extremity. We diagnosed VACD and performed surgery for cyst removal as well as patch angioplasty and thrombectomy of the right common femoral vein. The patient received anticoagulants for 6 mo and has been doing well without recurrence for 1 year postoperatively.
CONCLUSION
Recurrent VACD requires complete removal of the connections to the joint cavity to prevent recurrence.
Bilateral snapping triceps syndrome: A case report
Authors: Cho Chul-Hyun , Lim Kyung-Hwan , Kim Du-Han 
Published: December 2023

BACKGROUND
Snapping triceps syndrome (STS) is a rare disease, while occurrence of bilateral STS is extremely rare. It is usually accompanied by dislocation of the ulnar nerve and double snapping is a clinically important feature. However, to the best of our knowledge, there has been no report of bilateral STS in young active patient.
CASE SUMMARY
A 23-year-old male presented with a complaint of discomfort and snapping on the medial side of both elbows while performing push-ups. On physical examination, two distinct snaps that were both palpable and audible were detected on additional clinical examination. Dynamic ultrasonography showed that the ulnar nerve and the medial head of the triceps were dislocated anteriorly over the medial epicondyle of the elbow during flexion motion. Finally, he was diagnosed as dislocation of the ulnar nerve and STS. Staged anterior subcutaneous transposition of the ulnar nerve combined with partial resection of the snapping portion of the triceps was performed. The patient’s pain and snapping symptoms were resolved immediately after surgery. Three months later, the patient was completely asymptomatic and returned to normal activity.
CONCLUSION
STS should be included in the differential diagnosis for active young patients who present with painful snapping on the medial side of the elbow joint, particularly when dislocation of the ulnar nerve is detected. Dynamic sonography is used to assist in accurate diagnosis and differentiation between isolated dislocation of the ulnar nerve and STS.

Authors: Dubovik I. E. , Sharipova M. Yu. 
Published: December 2023

Studies of epiphytic cyanobacterial-algal cenoses along the highways of Ufa were carried out on five species of woody plants: deciduous (Betula verrucosa Ehrh., Populus nigra L., Tilia cordata Mill., Sorbus aucuparia L.) and coniferous (Picea obovata Ledeb.). A large species diversity of algoepiphytes from 5 divisions, 7 classes, 12 orders, 30 families, 48 genera and 85 species and intraspecific taxa was revealed. Epiphytes of the divisions Chlorophyta and Cyanobacteria dominated (41 and 38 species and intraspecific taxa, respectively), leading families - Oscillatoriaceae and Chlorococcaceae, genera - Phormidium, Leptolyngbya, Nostoc, Chlorococcum.The ecological analysis made it possible to identify six morphotypes. The predominance of colonial-coccoid algae was shown, which made up 31 taxa (36.5 % of the total). Trichal forms take the second place - 26 species (30.6 %), coccoid immobile - 22 species (25.9 %). The spectrum of ecobiomorphs of epiphytic cyanoprokaryotes and algae included 11 life forms: Ch32P16C11CF6aer6H4X4PF3hydr1B1аmph1. Oligoatmophytes have the highest species representation -77 %, mesoatmophytes - 17 %, the group of polyatmophytes is sharply depleted - 6 %. Comparison of the obtained results with the control in ecologically clean habitats showed no difference in the taxonomic and ecological composition of cyanobacterial-algal growths, the number of living cells.
Possibilities to measure the concentration of sodium dithionite in textile applications by means of amperometric sensors
Authors: Westbroek P. , Govaert F. , Gasana E. , Temmerman E. , Kiekens P. 
Published: December 2023

Abstract
By using linear sweep voltammetry and chronoamperometry at a rotating disc electrode it was found that sodium dithionite can be oxidised at several electrode materials. At platinum, palladium, glassy carbon and gold an oxidation reaction was observed that showed promising characteristics for analytical purposes and sensor development. The limiting current signal at a potential of +0.3 V vs. SSE is proportional to the concentration of sodium dithionite, the electrode reacts almost immediately on a change of concentration of sodium dithionite and experimental proof is given that the electrode is stable for at least 3 days without recalibration. The electrode can be calibrated by a one point calibration because the calibration curve is linear and goes through the origin.

Published: December 2023

Abstract
A procedure based upon image analysis has been adopted to study the influence of several physical parameters on bubble size in foam. A procedure has been described to account for the distribution of bubble size. Foam was generated in a rotor-stator mixer. In the present research, the nature of the surfactant, liquid viscosity, solid phase content, and rotational speed of the mixer were varied. All parameters were found to influence the bubble size and its distribution to a certain extent. These effects were qualified experimentally.
NON-WOVENS FROM COTTON FIBRES FOR ABSORBENT PRODUCTS OBTAINED BY THE NEEDLE-PUNCHING PROCESS
Authors: Kiekens Paul , Zamfir Maria 
Published: December 2023

Abstract
The use of non-wovens as absorbent products is increasing, as is the consumption of cotton fibres as raw materials for these products. This paper presents some results concerning the obtaining of absorbent non-woven products made from cotton fibres. A fibrous web was formed by the superposition of cotton bands as a short layer. Special needle types supplied by SINGER Spezialnadelfabrik GmbH & Co. KG were used during the needle-punching process. Equations of variation of liquid absorption speed and surface weight have been analysed in order to optimise the needle-punching process of the cotton fibrous webs.

Published: December 2023

Abstract
The implementation of truly wearable instrumented garments capable of recording biomechanical variables is crucial to several fields of application, from multi-media to physical rehabilitation, from sporting to artistic fields. Here we report on wearable devices which are able to read and record the posture and movements of a subject wearing the system. The sensory function of the garments is achieved by fabric strain sensors, based on threads coated with polypyrrole or carbonloaded rubbers. The presence of conductive elements gives these materials piezoresistive properties, enabling the detection of local strain on the fabric. Strips of strain fabrics are applied together with conductive tracks at strategic points in a shirt and a glove in order to detect the movements of the principal joints. The ‘smart shirt’-sensing architecture can be divided into two parts: a textile platform, where a wearable device acquires biomechanical signals, and a hardware/software platform, to which a wireless communication system sends the acquired data after electrical conditioning.

Published: December 2023

Abstract
Lyocell fibres have made a special impact on the worldwide textile market since their appearance. The trends in the field of textile fibres and the necessity of increasing the competitiveness of textile articles motivated an analysis of lyocell fibres’ potential for the garment sector, and especially for fashion. To this end, some different finishing experiments on lyocell woven fabrics have been conducted. The technological experiments had the primary fibrillation effect-enzymatic defibrillation-secondary fibrillation in view. For obtaining these effects, rope finishing with/without woven fabrics causticising was carried out, followed by defibrillation (biopolish treatment) before or after dyeing, using different cellulasic enzymes such as Bactosol CA (Clariant), Perizym 2000 and Perizym LYO (Textil Chemie GmbH Dr. Petry). The experiments considered the evidence of the influence of these technological stages on the surface modification that appears in finishing lyocell textile materials.
BIOACTIVE SURGICAL SUTURES
Authors: Zhukovsky V. 
Published: December 2023

Abstract
Investigations carried out into the development of bioactive surgical sutures and radioactive fibres are presented. Anti-microbial surgical sutures, which for a long period provide the wound with the antibiotics settled in their structure, can be of considerable use for precautions and treatment of surgical sepsis. Simultaneously the hydrolytic influence of proteolytic enzymes on the necrotising tissues, which serve as a nutrient medium for microbes, is desirable. The anaesthetic and anticancerous properties of sutures are also of such importance. Antibiotics (such as clindamycin, gentamycin, lincomycin etc.), proteolytic enzymes (such as tripsin and pepsin), anaesthetics (such as lidocaine, novocaine, trimecaine, and pyrocaine), and anti-tumour medicaments (such as prospydin, 5- fluorocyl, sarcolysin etc.) were fixed by us separately or in different combinations onto cationexchanging polypropylene fibres with the help of ion-exchanging bonds. A principally new type of biologically active surgical fibres is radioactive fibres which exhibit their action by the emanation of ionising radiation from radioactive isotopes fixed in the fibres' structure. Sulphur-35 isotopes emanating soft beta-rays, and phosphorus-32 isotopes emanating much harder electrons were fixed by us onto polypropylene, polyethylene terephthalate, polyamide, and polyvinyl alcohol fibres by firm covalent bonds. Biological, medical and clinical tests showed the high effectiveness of the biological active sutures developed by us, as well as that of the radioactive surgical fibres used in different forms.
THE MECHANISM OF END BREAKAGE IN RING SPINNING: A STATISTICAL MODEL TO PREDICT THE END BREAK IN RING SPINNING
Authors: Ghosh Anindya , Ishtiaque Sayied , Rengasamy Seenivasan , Patnaik Asis 
Published: December 2023

Abstract
The mechanism of end breakage in ring spinning is a complex phenomenon, and is entirely different from the yarn failure mechanism during a tensile test. In this paper a possible mechanism of end breakage is reported. A statistical model is developed for predicting the likely end breakage rate in ring spinning. The important factors in governing end breaks are the mean yarn strength, yarn strength variation, mean value of the peak spinning tensions and the variation of yarn mass irregularity. Some practical aspects have also been discussed to tackle the problem of when the breakage rate suddenly increases.
