Effects of toolpath on defect phenomena in the incremental forming of thin polycarbonate sheets
Authors: Formisano Antonio , Boccarusso Luca , De Fazio Dario , Durante Massimo 
Published: March 2024

Abstract

The incremental sheet forming has been largely investigating in the last two decades because of its versatility and cost-effectiveness which make this technology especially viable for manufacturing highly customized parts, as well as small and medium-sized batches. One of its main strengths is that it allows reaching greater formability, compared to conventional sheet forming processes; in contrast, defect phenomena like twisting and wrinkling occur frequently and strongly influence the geometric accuracy of the formed parts. All these aspects are dramatically accentuated when forming soft materials like thermoplastics. With these premises, the following research aims to investigate the effects of the toolpath strategy on the occurrence of failures and defects in the incremental sheet forming under very severe process conditions; thin polycarbonate sheets were formed to obtain cone frusta with a fixed wall angle, imposing four unidirectional helical trajectory-based toolpaths, one traditional and three stair strategies. The analysis of the forming force trends, the evaluation of the worked surface quality and the monitoring of the defectiveness highlight understanding the advantages of an appropriate toolpath strategy to improve the accuracy of the incremental sheet forming of thermoplastic parts.

Abstract

Objective.
To develop a porcine model for laparoscopic intersphincteric resection (ISR) targeting ultra-low rectal cancer.
Methods.
Six Bama mini-pigs underwent a standard laparoscopic ISR procedure: 1. High ligation and transection of the inferior mesenteric vessels; 2. Exposure and sparing of the pelvic autonomic nerves; 3. Dissection of the rectum down to the levator hiatus; 4. Dissection and transection of hiatal ligament and rectourethralis muscle; 5. Transanal full-thickness circumferential dissection of the anal canal at the level of intersphincteric groove (1cm distal to the dentate line), involving the rectal circular muscle and the conjoint longitudinal muscle; 6. Dissection of the intersphincteric space (ISS) until convergence with the laparoscopically dissected plane with resection of the distal rectum and internal sphincter muscles; 7. End-to-end handsewn coloanal anastomosis. Subsequent to the surgical procedure, ISR modeling was executed. Pathological evaluations were conducted to ascertain the precision of the ISR. Furthermore, postoperative fecal incontinence scores were systematically assessed on a weekly basis throughout a 12-week post-surgery follow-up period.
Results.
All six pigs survived surgery without conversion to an open approach. There were no occurrences of incisional infection or any surgical complications, including anastomotic leakage, anastomotic bleeding, or ileus. Postoperatively, one pig manifested constipation and three exhibited anal redness, both conditions ameliorating within a week. No erosive ulcers were detected. Notably, all animals exhibited fecal staining on their tails within the first two weeks post-surgery, transitioning to formed feces by the third week. Improvement in defecation frequency was observed after six weeks, with a noticeable reduction in defecation areas after one month. Incontinence scores, evaluated three months post ISR surgery, revealed no significant abnormalities in anal function compared to preoperative assessments.
Conclusions.
This study established a replicable porcine model for laparoscopic ISR, demonstrating its potential utility in clinical and fundamental research related to ultra-low rectal cancer treatment.

Abstract

The role of the bone marrow (BM) microenvironment in regulating the antitumor immune response in Waldenstrom macroglobulinemia (WM) remains limited. Here we transcriptionally and phenotypically profiled non-malignant (CD19− CD138−) BM cells from WM patients with a focus on myeloid derived suppressive cells (MDSCs) to provide a deeper understanding of their role in WM. We found that HLA-DRlowCD11b+CD33+ MDSCs were significantly increased in WM patients as compared to normal controls, with an expansion of predominantly polymorphonuclear (PMN)-MDSCs. Single-cell immunogenomic profiling of WM MDSCs identified an immune-suppressive gene signature with upregulated inflammatory pathways associated with interferon and TNF signaling. Gene signatures associated with an inflammatory and immune suppressive environment were predominately expressed in PMN-MDSCs. In vitro WM PMN-MDSCs demonstrated robust T-cell suppression, and their viability and expansion was notably enhanced by G-CSF and TNFα. Furthermore, BM malignant B-cells attracted PMN-MDSCs to a greater degree than monocytic MDSCs. Collectively, these data suggest that malignant WM B cells actively recruit PMN-MDSCs which promote an immunosuppressive BM microenvironment through a direct T cell inhibition, while release of G-CSF/TNFα in the microenvironment further promotes PMN-MDSC expansion and in turn immune suppression. Targeting PMN-MDSCs may therefore represent a potential therapeutic strategy in patients with WM.

Abstract

Sign language is a vital form of communication since it provides an alternative to spoken language expression for those who are deaf or hard of hearing. People who use sign language still have restricted access to information and communication, especially in languages other than English. The primary purpose of this paper is focused on building the communication bridge for them. Convolutional Neural Network (CNN's) is a popular machine learning approach and has been taken advantage of in the current research to ease the translation of Hindi text and speech to Indian Sign Language (ISL). Along with CNNs the paper also contains Long Short-Term Memory (LSTM) and dense layers to increase the accuracy of the research. There are several potential uses for the proposed CNN-LSTM-Dense Sign Language Conversion System, including removing communication barriers in healthcare settings, educational settings, and everyday encounters. Its main objective is to improve the deaf and hard of hearing community's overall quality of life and social integration in India while fostering inclusion and equal opportunity. For the deaf and hard of hearing community in India, the Sign Language Conversion System for Hindi Language provided in this research article marks a big step forward in assuring information and communication accessibility. The system's ability to enable real-time translation of Hindi text and speech into ISL gestures, utilizing the CNN-LSTM-Dense architecture, holds great promise for promoting inclusivity and enhancing the quality of life for people who use sign language as their primary form of communication.

Abstract
Securing image transmissions has become critical as the demand for image sharing and storage grows. In some commercial uses, in order to achieve a balance between encryption security and efficiency, some researchers have tried to encrypt only the region of interest of the user in the image. In order to accurately encrypt region of interest images, this paper proposed a region of interest image encryption algorithm based on lifting scheme and object detection. The algorithm automatically identifies the region of interest in the image and encrypts it securely and effectively. Firstly, the region of interest in the image is detected using the object detection model, where we modify the non-maximum suppression algorithm to address the problem that the detection box output from the object detection model does not completely contain the region of interest, avoiding the risk of privacy leakage. Then the existing pixel extraction method for region of interest images is improved to extract the pixels from the region of interest images at a faster speed, which improves the overall efficiency of the algorithm. Finally, based on the thought of wavelet lifting transform, a two-layer hybrid lifting scheme encryption algorithm is proposed to encrypt the extracted pixels. Experimental results and security analyses show that our proposed algorithm can effectively protect all objects at once with high security.

Investigating climatic and human effects on the decline in the groundwater level (a case study of the Kuhdasht plain)
Authors: Hassanzadeh Reza , Peyman Safa , Hassanzadeh Amirmohammad 
Published: March 2024

ABSTRACT

This study has been investigated using the new criterion measuring complexity Hilbert-Huang entropy (HHE), changes, and fluctuations in groundwater levels under the influence of climate change factors and humans. In this regard, the 120-month time series of groundwater level, precipitation, temperature, and runoff parameters (period 2009–2018) are first divided into five 24-month periods, then by applying the Hilbert-Huang transform. Each period is decomposed down into smaller periods, and finally, the HHE criterion measures the complexity of the time series. The examination of changes in the HHE complexity criterion shows a decrease of 2.02, 2.93, and 29.58% in the groundwater level in the second, third, and fourth periods. Also, according to the results of changes in the complexity of precipitation and temperature time series as climate change factors, these two parameters have decreased in the third and fourth periods, with the rate of decrease for the temperature time series being 18.8 and 8.3%, respectively, and for the precipitation time series is obtained by 30.6 and 4.4%, respectively. Hence, according to the results, the discharge parameter, as a human factor in the second and fourth periods, shows a decrease of 8.6 and 39.1%, respectively.
