Directivity of photoacoustically generated ultrasound from a thin tube embedded in the soft phantom
Authors: Wang Kun , Wada Yuji , Nakamura Kentaro
Published: February 2023

Our previous study has revealed that acoustic resonances have non-negligible effects on photoacoustic signals for a liquid sample confined in a thin tube. In this paper, we present numerical and experimental studies on the effects of tube hardness on the directivity of the generated photoacoustic signal. A thin glass capillary and silicone tube of 1 mm in diameter were tested using a pulsed light of 637 nm wavelength. Black ink was confined in the glass capillary and silicone tube as a photoacoustic sample material. In the glass capillary, acoustic resonance modes in the glass capillary were efficiently excited, and clear directivity was observed in the generated photoacoustic signals. On the other hand, little resonance was stimulated in the silicon tube because of the acoustic impedance matching between the sample and surrounding media, which resulted in the weak confinement of acoustic waves. The results suggest a possibility of characterization of the physical properties of thin tubes.
Tight-binding analysis of the effect of strain on the band structure of GaN
Authors: Miyazaki Wataru , Tanaka Hajime , Mori Nobuya
Published: February 2023

The effects of strain on the band structure of GaN are investigated by using an empirical tight-binding method. The impacts on its bandgap, carrier effective mass, and group velocity are discussed. By analyzing the orbital components at the top of the valence band, the cause of the variation of the band structure including effective-mass exchange is discussed. Analysis of the average group velocity indicates that tensile uniaxial or compressive biaxial strain may be beneficial for achieving higher breakdown voltage in vertical GaN devices due to the smaller group velocity of the valence band. For the same reason, we also predict higher breakdown voltages due to tensile biaxial strain for horizontal devices.

A forgó mozgást végző tengelyek, gépelemek egyik működés közbeni fontos jellemzője a kritikus fordulatszám, mely a forgó mozgást végző összeállítás sajátfrekvenciájával függ össze. A valóságban a tengely rugalmas elem, amelyre, ha egy kiegyensúlyozatlan forgórészt szerelnek, a szögsebesség négyzetével és az excentricitással arányos centrifugális erő hat. Az ehhez köthető gerjesztő hatások káros rezgésekhez vezethet. A kritikus fordulatszámon a forgórész nyugtalanul viselkedik, a gép rezgéseinek amplitúdója megnövekszik. Tervezésnél gondoskodni kell arról, hogy a kritikus fordulatszámon a gép tartósan ne üzemelhessen. Az ilyen rendszerek kritikus fordulatszámának meghatározására léteznek mechanikai modellek, azonban pontosabb képet kapunk a valós tengely forgás közben fellépő rezonanciájának mérésével.

Authors: Sayari Chaima , Simon Andrea , Baumli Peter
Published: February 2023

The use of high-quality thermal insulation materials to improve the energy efficiency of buildings is strongly increasing. Foam glass, a durable and porous material that is resistant to almost all substance effects, is one of the best thermal insulation materials. Glass foaming is a complicated process that is affected by the types of foaming agents used in the initial composition of the mixture and the mode of foaming. The influence of all components of the mixture - glass matrix and foaming agent - is discussed in this paper. Three types of glass powder (alkali frit, soda-lime silicate and borosilicate) were determined to be the matrix material. The foaming agents generate a gas phase via thermal decomposition of eggshell or a chemical reaction with the oxygen in the molten glass via SiC and coffee ground waste. The powder compacts fired at 900 °C for 10 minutes with a foaming agent content of 2 wt % presented excellent thermal insulation properties by using soda-lime silicate glass with SiC and eggshell foaming agents mixtures. The coffee ground waste-glass mixtures show inferior thermal insulation properties with each different glass powder.

Published: February 2023

Background: The WHO considers elderly as an individual who is ≥ 60 y of age, and there are ≥ 37.7 million elderly people. In 2006, the ACERTO Project (Acceleration of Total Post-Operative Recovery) was introduced in Brazil in colorectal surgeries, and in elderly orthopedic femur fractures in 2010, with primary objective for the patient to early return to independent life. The objective of this descriptive study is to evaluate the clinical results 870 elderly patients undergoing surgical treatment of femoral fractures in ten years (2010-2019) after employing the perioperative acceleration protocol.

Methodology: It was a cross-sectional, prospective study in patients ≥ 60 y, of both genders, undergoing corrective hip fracture for ten years at a hospital covered by the Brazilian Public Health System (SUS). The data regarding preoperative condition of the patients, fasting status, mode of anesthesia, drugs used, intra-operatively measured variables and immediate post-operative variables measured in the PACU, quality of lumbar plexus block analgesia, presence of delirium in the first day of postoperative was obtained from the study protocol. The deaths during the first postoperative month were noted.

Results: A total of 829 patients underwent surgery for a fracture of the hip, under spinal anesthesia, of whom 583 were women and 246 were men. The average hospital stay was 10.2 ± 7.1 days, and it was associated with the age. The mean fasting time was 2:50 ± 0:32 h. The dose of isobaric bupivacaine was 9.62 ± 1:85 mg. The cephalad spread varied from T12 to T5. The duration of the spinal block was 2:50 ± 0:38 h, the time for the use of dextrinomaltose in PACU was 1:39 ± 0:47 h, the time in the PACU was 2:03 ± 0:46 h and the time to reintroduce normal meals was 6:18 ± 1:02 h. Arterial hypotension occurred in 36 (4.3%) patients, bradycardia in 4 (0.4%), and delirium in 16 patients. Eleven (1.3%) patients were sent to the ICU due to surgical problems. There were no deaths directly related to anesthesia or surgery.

Conclusion: The implementation of the ACERTO Project in 829 patients with femur fracture of the Brazilian Public Health System, showed favorable results regarding length of stay, patient satisfaction, decreased use of bladder tube and drains, and referral to ICU, with early discharge to residence.

Authors: Urooj Sana , Mughal Anum , Shareef Madiha , Naz Arshi , Shah Muzaffar Umair , Siddiqui Safia Zafar
Published: February 2023

Background & objectives: Spinal anesthesia is the preferred technique for obstetric patients as it is economical, simple to perform, has a rapid onset and provides complete muscle relaxation. A variety of adjuvants have been used to enhance or prolong its effects. We compared the effects of dexmedetomidine and fentanyl on the onset and recovery times of sensory and motor blockade as well as on hemodynamics, postoperative complications and duration of postoperative analgesia in parturients undergoing lower segment cesarean section (LSCS). Methodology: It was a prospective, double blind, randomized controlled trial. Sixty healthy parturients having cesarean delivery under spinal anesthesia were randomly divided into two equal groups. Group BD was given 10 mg bupivacaine plus 5 µg of dexmedetomidine and Group BF was given 10 mg bupivacaine plus 10 µg of fentanyl. Parturients was then observed for the onset and recovery times of sensorimotor blockade, hemodynamics, postoperative complications and postoperative analgesia.

Results: There was no statistically significant difference in the onset of sensorimotor block between the groups. The time to complete sensory and motor recovery was significantly prolonged in Group BD (P = 0.01 and P = 0.0001 respectively) as compared to Group BF. Both groups did not show significant differences in hemodynamic changes, but there was a reduction in systolic and diastolic blood pressures ≥ 20% from baseline intraoperative. The VAS at 3 and 4 h postoperatively in the Group BD was significantly lower (P = 0.02 and P = 0.01 respectively). The incidence of complications was found comparable in two groups, except incidence of hypotension and nausea was more in the Group BD compared to Group BF (P = 0.006 and 0.002 respectively).

Conclusion: Although intrathecal dexmedetomidine prolongs the duration of sensory block, with comparable hemodynamic changes and good postoperative analgesia, prolonged motor block due to it, compared to intrathecal fentanyl, is not a desirable outcome particularly in short duration surgeries like LSCS, which can increase discharge time from post anesthesia care unit (PACU) to the ward.

Use of Dexmedetomidine for Anesthesia and Pain Management
Authors: Nazir Wajahat , Khan Ahsun Waqar
Published: February 2023

Background & objective: Since 1999, dexmedetomidine has been used in several patient populations after its approval as a sedative by the FDA. Subsequently, a large number of clinical trials on its benefits have been published widely in the literature. This review aims to update readers regarding recent evidence for approved as well as novel uses of dexmedetomidine and identify future areas of clinical research involving this relatively new drug.

Sources: Randomized controlled trials conducted between January 2000 and August 2021, which compared dexmedetomidine with other sedative agents used in adult and pediatric patients undergoing mechanical ventilation in ICU, bronchoscopy and endoscopic procedures, general and locoregional anesthesia and chronic pain management were included in this review of the literature. PubMed, Science Direct, the Cochrane library and Google Scholar were used as databases.

Implications: Dexmedetomidine is a multipurpose drug that has found unparalleled utility in intensive care medicine and anesthesiology. Its various advantages over traditional sedative agents have been documented, including decreased duration of mechanical ventilation, decreased incidence of delirium, perioperative analgesia and organ protective properties. Recently there has been mounting interest in dexmedetomidine as an analgesic adjunct in chronic and cancer pain management. However, there is still a paucity of well controlled studies evaluating the use of dexmedetomidine outside of a traditional sedative/analgesic role. The future direction of the research may focus on long term clinical benefits of dexmedetomidine in certain perioperative populations and its non-conventional use in palliative care and pain medicine.

Published- Comparison between supra-scapular nerve block combined with axillary nerve block and interscalene brachial plexus block for postoperative analgesia following shoulder arthroscopy
Authors: Elbermway Mahmoud Saeed , Elshantory Sherif Farouk , Aly Rania Magy , Mahran Mostafa Gamale
Published: February 2023

Background & objective: Inter-scalene brachial plexus block (ISB) is the gold standard for postoperative pain management in shoulder surgery. Although, this method has its side-effects and possibly complications. Supra-scapular nerve block and axillary nerve block have also been used in upper limb procedures. We compared ISB with the blockade of supra-scapular and axillary nerves (called shoulder block) for postoperative analgesia after shoulder arthroscopic surgical operation under ultrasound guidance (USG) and nerve stimulators.

Methodology: It was a prospective, randomized, comparative study.

Results: The VAS pain scores at different times postoperatively were not significantly different between the ISB and ShB groups (P = t 0.071, 0.28, 0.378, 0.358, 0.451 at 2, 4, 8, 16, and 24 h respectively. VAS 0 was significantly difference (P = 0.029) but still the VAS score was less than 3, so no pain killers were given.

Conclusion: Ultrasound guided supra-scapular and axillary nerve blocks ae equally effective as inter-scalene brachial plexus block for postoperative analgesia in shoulder arthroscopic surgery with less side-effects.

Published: February 2023

Background: The present study evaluated the association of pre-operative pain education with the postoperative pain perception among the patients undergoing coronary artery bypass grafting (CABG).

Methodology: This randomized controlled trial was performed with cardiac patients undergoing CABG at Punjab Institute of Cardiology (PIC), Lahore. Eighty patients (47 males and 33 females) were selected and randomly assigned, either to the interventional group (40 patients) or the control group (40 patients). Those with any psychiatric disorder, past pain history, and those addicted to the opioids were excluded. The interventional group received preoperative pain education (booklet by Canadian Pain Society). Pre-operative and post-operative pain questionnaires including Brief Pain Inventory (BPI) scales were study tools. Chi-square and independent t-test, were used for association and comparison respectively.

Results: No significant difference was found between comparative groups regarding pre-operative pain perception, while significant difference was noted between the two groups regarding post-operative clarification of pain management (P < 0.001), preparedness for stronger analgesics (P < 0.001), risk of analgesia dependence (P < 0.001), fear of nausea related to pain-killers (P < 0.001), and threat of constipation with use of analgesics (P < 0.001). BPI scale showed that the average pain score of interventional and control groups were 17.25 ± 5.26 and 32.17 ± 2.51 respectively.

Conclusion: CABG patients who received preoperative pain education reported significantly less postoperative pain after the CABG, compared to the controls.

Laryngeal granuloma formation is an uncommon complication following endotracheal intubation. We describe a case wherein a pedunculated laryngeal granuloma developed following endotracheal intubation for coronary artery bypass grafting (CABG) surgery. The intubation was atraumatic, and extubation in the ICU was without complication. Following an initial uneventful recovery, the patient developed laryngopharyngeal reflux and contracted an upper respiratory infection (URI), at which point she progressively developed hoarseness of voice and foreign body sensation over a period of three months. We present her case discussing the management of a massive pedunculated laryngeal granuloma.

Published: February 2023

Summary: The frequency of sexual assaults is rising by every passing day, in developed as well as non-developed countries. Many of the victims report to hospitals for possible surgery, due to related or non-related causes. The alien atmosphere of the operating rooms, the busy male and female staff, and the fear of being stripped during surgery are the main factors which need to be addressed with an empathic, if not a sympathetic attitude. Verbal contact being the most valuable tool. The authors have brought this important aspect of the clinical practice to limelight.

Automated Detection of Hydrothermal Emission Signatures from Multi-Beam Echo Sounder Images Using Deep Learning
Authors: Mimura Kazuhide , Nakamura Kentaro , Takao Kazuhiro , Yasukawa Kazutaka , Kato Yasuhiro
Published: February 2023

Seafloor massive sulfide deposits have attracted attention as a mineral
resource, as they contain a wide variety of base, precious, and other
valuable critical metals. Previous studies have shown that signatures of
hydrothermal activity can be detected by a multi-beam echo sounder
(MBES), which would be beneficial for exploring sulfide deposits.
Although detecting such signatures from acoustic images is currently
performed by skilled humans, automating this process could lead to
improved efficiency and cost effectiveness of exploration for the
seafloor deposits. Herein, we attempted to establish a method for
automated detection of MBES water column anomalies using deep learning
models. First, we compared the “Mask R-CNN” and “YOLO-v5” detection
model architectures, wherein YOLO-v5 yielded higher F1 scores. We then
compared the number of training classes and found that models trained
with two classes (signal and noise) exhibited superior performance
compared with models trained with only one class (signal). Finally, we
examined the number of trainable parameters and obtained the best model
performance when the YOLO-v5l model with a large trainable parameters
was used in the two-class training process. The best model had a
precision of 0.928, a recall of 0.881, and an F1 score of 0.904.
Moreover, this model achieved a low false alarm rate (less than 0.7%)
and had a high detection speed (20−25 ms per frame), indicating that it
can be applied in the field for automatic and real-time exploration of
seafloor hydrothermal deposits.

ProactiV: Studying deep learning model behavior under input transformations
Authors: Prasad Vidya , van Sloun Ruud , Vilanova Anna , Pezzotti Nicola
Published: February 2023

Deep learning (DL) models have shown performance benefits across many applications, from classification to, more recently, image-to-image translation. However, low interpretability often leads to unexpected model behavior when deployed in the real world. Usually, this unexpected behavior is because the training data domain does not reflect the deployment data domain. Identifying model breaking points under input conditions and domain shifts, i.e., input transformations, is essential to improve models. Although visual analytics (VA) has shown promise in studying the behavior of model outputs under continually varying inputs, existing methods mainly focus on per class or instance-level analysis. We aim to generalize beyond classification where classes do not exist and provide a global holistic model behavior overview under co-occurring input transformations. We present a DL model-agnostic VA method (ProactiV ) to help model developers proactively study output behavior under input transformations to identify and verify breakpoints. ProactiV relies on a proposed input optimization method to determine how far a given transformed input has to move in the input data manifold to achieve the desired output. The data from this optimization process allows the study of global and local model output behavior under input transformations at scale. Additionally, the optimization method provides insight into the input characteristics that result in desired outputs and helps recognize model biases. We highlight how ProactiV effectively supports studying model behavior under input transformations to identify and verify model breakpoints with example classification and image-to-image translation tasks.
A Hierarchical Separation and Classification Network for Dynamic Micro-Expression Classification
Authors: Vice Jordan , Khan Masood , Tan Tele , Murray Iain , Yanushkevich Svetlana
Published: February 2023

 Models of seven discrete facial expressions are built on macro-level facial muscle variations for separating distinct affective states. We propose a step-wise Hierarchical Separation and Classification Network (HSCN) that discovers dynamic and continuous macro- and micro-level variations in facial expressions. The HSCN first invokes an unsupervised cosine similarity-based separation method on continuous facial expression data and extracts twenty-one dynamic expression classes from the seven common discrete affective states. Separation between the clusters is then optimised for discovering the macro-level changes in facial muscle activations followed by splitting the upper and lower facial regions for realising and modelling changes pertaining to upper and lower facial muscle activations. A linear discriminant space is developed for clustering the upper and lower facial images on the basis of similar muscular activation patterns. Actual dynamic data and linear discriminant features are mapped for developing a rule-based expert system that would facilitate classification of twenty-one upper and twenty-one lower facial micro-expressions. Using the random forest algorithm, classification accuracies of 76.11\% were observed for dynamic macro-level facial expression classification. A support vector machine provided 73.63\% and 87.68\% accuracies respectively while classifying upper and lower facial micro-expressions. This work provides a novel framework for the dynamic assessment of affective states. Reported methods and results also provide new insight into the dynamic analysis of facial expressions of affective states. 
Low-cost Thyroid Nodule Diagnosis Using a Supervised Autoencoder Neural network
Authors: Barlaud Michel
Published: February 2023

Background: Thyroid Nodules are more and more widespread, with the frequency of thyroid cancers increasing accordingly. In routine practice, the practician's goal is to determine if a nodule is malignant or suspicious, and thus requires surgery. However, nearly one-third of thyroid nodules fall into the 'indeterminate' classification segment, often leading to the use of surgery as a diagnostic tool, when it could have been avoided with a better preoperative diagnosis. Molecular tests exist to address this issue, but they are markedly onerous.

Results: In this paper, we present an accurate, cost-less method to predict the malignancy of thyroid nodules using a categorical thyroid nodules dataset. The prediction is achieved through the use of a new supervised autoencoder neural network. Results show that the Supervised Autoencoder Neural Network outperforms classical classification methods on all evaluation metrics. A proof-of-concept Graphical User Interface was developed to demonstrate the medical usefulness of the latent space of the trained network.

Conclusions: Aside from the prediction itself, the Supervised Autoencoder Neural Network provides three medically interesting characteristics: a prediction confidence score, consistent feature ranking, and an interpretable latent space. All of those characteristics are valuable from the practician's point of view, as they allow for an efficient, cost-less and well-informed prognosis.

Use Secret-Hashing Technology to Resist Side-Channel Attacks Based on Round-Keys
Authors: Chien Chun-Tsai
Published: February 2023

The development of modern cryptography has not specifically prevented Side-Channel attacks at the outset. Today, the rapid growth in Side-Channel Attacks is a significant threat. This article proposes a Secret-Hashing method that improves the main drawback of the explicitly reversible AES key expansion function. Using an extra Secret-Hashing function based on round-keys of AES to generate new round-keys will break the reversibility between the original round-keys. Let the initial attack requires only the easiest one of the round-keys to be necessary for all round-keys to complete the cracking of AES’s encryption and decryption, increases the resistance of the AES algorithm to Side-Channel Attacks by 10 to 100 times. The method is compatible with the original AES algorithm and signal leakage countermeasures, and the AES encryption and decryption process do not increase any extra payload.

Published: February 2023

This article presents a comparison of 4 different types of rectifier circuits for piezoelectric energy harvesting. Energy is harvested from multiple piezoelectric elements embedded in an in?sole while simultaneously collecting gait information of the subject wearing it. The study is based on an asymmetric signal generated while walking and the harvested energy is utilized to operate a system under a fixed electrical load. The influence of back-up battery and insole design optimization on the accuracy of collected information is taken into consideration. A comprehensive approach for shoe insole application based on simultaneous piezoelectric sensing and energy harvesting is presented in this work. 
From Finite Element Simulations to Equivalent Circuit Models of Extracellular Neuronal Recording Systems based on Planar and Mushroom Electrodes
Authors: Leva Federico , Verardo Claudio , Palestri Pierpaolo , Selmi Luca
Published: February 2023

A  methodology to build multi-compartment lumped elements equivalent circuits for the neuron/electrode systems is proposed. The equivalent circuit topology is derived by careful scrutiny of accurate multiphysics finite-elements method (FEM) simulations that couple ion transport in the intra- and extracellular fluids, activation of ion channels in the cellular membrane, and signal collection by the electronic readout, thus improving upon most common area contact models.

We show that the equivalent circuits derived with our method match with good accuracy the reference FEM simulations over a wide range of geometrical/physical parameters such as the neuron and electrode size, the thickness of the electrolytic cleft, the input impedance of the readout amplifier, even in presence of nonuniform ion channel distributions. The impact of the number of compartments on the model accuracy is also analyzed in detail. We finally illustrate by FEM simulations the effect of extracellular ion transport on the reversal potentials of the Hodgkin-Huxley neuron model and how it can affect the recorded signal for very thin electrolyte clefts between the neuron and the electrode, in a way not yet captured by equivalent circuits of the neuron/electrode system.
Utopianism, History, Freedom and Nature: Shaw’s Theory of “Creative Evolution” in Saint Joan
Authors: Knapp Shoshana Milgram , Gabellone Anna Rita
Published: February 2023

This paper aims to investigate some important elements of the thought of George Bernard Shaw, more commonly known as one of the most famous playwrights of the twentieth century. Shaw’s philosophy dwells on the relationship between man and nature and especially the concept of freedom. Among all his works, it was decided here to analyse Saint Joan. In re-imagining the historical Joan as a heroine in a play of ideas, Shaw made use of the known facts about Joan of Arc and Joan’s statements at her trial. Nonetheless, he made changes to emphasize her personal dignity and independence by contrast with the tyranny of institutions. Although he departed from the historical background, whitewashed her adversaries, and condensed episodes in Joan’s biography, he sought to be true to her confidence, courage, integrity, and common sense. His theatrical presentation is, in some respects, at odds with the Preface that accompanies the published play.
A Dimensão Ontológica do Antropoceno: Pensamento Ameríndio e Algumas Ideias para Adiar o Fim do Mundo
Authors: Neuenschwander-Magalhães Juliana
Published: February 2023

This article observes the imagination of the end of the world in the Anthropocene era and, at the same time, intends, from an anthropological turn that considers other possibilities of human existence on Earth, to imagine how Amerindian cosmovision can promote not only an ontological but also an epistemological turn in the field of contemporary law and politics. A conflicted but not impossible dialogue between the naturalistic matrix of Western thought and Amerindian multinaturalism, in search of “ideas to postpone the end of the world”.
Educare, mobilitare, organizzare: linee di lettura del pensiero di Bhimrao Ramji “Babasaheb” Ambedkar
Authors: Spini Debora
Published: February 2023

Bhimrao Ramji Ambedkar is well known as one among the protagonists of India’s political history in the 20th century, as he played a major role in the struggle against the caste system, and in designing a pluralist and egalitarian democracy. Ambedkar’s intellectual legacy is a crucial tool for investigating the contradictions of the contemporary Indian political experience, and as such has much to offer to the international political-philosophical debate. This essay presents the main aspects of Ambedkar’s thought, focusing on themes such as his non-majoritarian conception of democracy, the tension between universality and difference in political citizenship, social and political equality, as well as his reflection on religious identity. Ambedkar’s intellectual profile will also be assessed in light of the ongoing debate on the status of a non-derivative Indian political thought.
