Trust in Vehicle-to-Vehicle Communication

In traditional Pedestrian Automatic Emergency Braking (PAEB) system, vehicles equipped with onboard sensors such as radar, camera, and infrared detect pedestrians, alert the driver and/ or automatically take actions to prevent vehicle-pedestrian collision. In some situations, a vehicle may not be able to detect a pedestrian due to blind spots. Such a vehicle could benefit from the sensor data from neighboring vehicles in making such safety critical decisions. We propose a trust model for ensuring shared data are valid and trustworthy for use in making safety critical decisions. Simulation results of the proposed trust model show promise

Aneurysmal bone cyst in proximal phalanx treated without bone grafting

Aneurysmal bone cyst involving the hand are a rare occurrence especially in the proximal phalanx. We report a case of 5 years old female child with proximal phalanx aneurysmal bone cyst treated without bone grafting. Magnetic resonance imaging may show fluid filled spaces but definite diagnosis can only be obtained histologically. It is a benign lesion still it can involve growth plate hence intervention is necessary. The treatment includes curettage with or without bone grafting

Aneurysmal bone cyst of medial end of clavicle: a rare case report

Aneurysmal bone cyst is a benign, but locally aggressive benign tumor. The clavicle being a rare site of tumors and very few cases of aneurysmal bone cyst of clavicle have been reported in literature. Due to its rarity of location of its presentation we hereby report a rare case of aneurysmal bone cyst of medial end of clavicle in a 20-year-old female which was treated by wide local resection and reconstruction

Twisted eleven-dimensional supergravity

We construct a fully interacting holomorphic/topological theory in eleven dimensions that is defined on products of Calabi-Yau fivefolds with real one-manifolds. The theory describes a particular deformation of the cotangent bundle to the moduli space of Calabi-Yau structures on the fivefold. Its field content matches the holomorphic (or minimal) twist of the eleven-dimensional supergravity multiplet recently computed by the second two authors, and we offer numerous consistency checks showing that the interactions correctly describe interacting twisted eleven-dimensional supergravity at the perturbative level. We prove that the global symmetry algebra of our model on flat space is an $L_\infty$ central extension of the infinite-dimensional simple exceptional super Lie algebra $E(5,10)$, following a recent suggestion of Cederwall in the context of the relevant pure spinor model. Twists of superconformal algebras map to the fields of our model on the complement of a stack of M2 or M5 branes, laying the groundwork for a fully holomorphic version of twisted holography in this context.Comment: 58 pages.

Intra-operative peri-articular cocktail injection in inflammatory arthritis patients undergoing total knee arthroplasty

Pain following TKA is often severe in most patients. The purpose of this case series was to assess the efficiency of intra-operative peri-articular cocktail injection in management of pain following total knee arthroplasty. This case series involves 16 patients with inflammatory arthritis of knee undergoing total knee arthroplasty (TKA). All patients had received peri-articular cocktail of drugs before the implantation of prosthesis with cement. In our study, there was significant improvement of Knee Clinical Score and Knee Functional Score following TKA. The mean KSS score was 37.5 (range: 31-44) improved to 92.5 (range, 86-99) and the functional score improved from 25.5 (range, 18-33) to 76 (range, 72- 80) at 6 months and 93 (range: 90-96) at 12 months. Intraoperative peri-articular injection with 20 ml of 0.5% ropivacaine, 1 ml of ketorolac, 1ml of clonidine and 0.5ml noradrenaline diluted in 20 ml of saline is effective in reducing immediate post-operative pain and thereby improving the overall functional outcome

A Prospective, Multicentric, Open label and Post Marketing Clinical Follow up Study to Monitor the Safety and Performance of Light Cured Limb Orthosis - FlexiOH® (Short Arm Immobilizer) in Fractures Distal Radius

Background: Distal forearm fracture is the most common fracture encountered in daily life. Patients with this type of injury suffer from meaningful pain after Emergency Department discharge. Various studies reported that short-arm, below-the-elbow casts perform as well as long-arm, above-the-elbow casts for maintaining a reduction of distal forearm fractures demonstrated with a comparable risk of complication. Consequently, short casts are the commonly used method of immobilization however, short casts carry a potential disadvantage. Objective: To evaluate the safety and efficacy of the next-generation FlexiOH® (Short Arm Immobilizer). Settings and Design: This is a prospective, multicentre, and open-label clinical trial conducted in 5 different sites in India by recruiting a total of 137 subjects who were presented with distal forearm fractures. Materials and M ethods: Vital signs, concomitant medication taken by subjects during the study, X-ray results, and adverse events caused during all three visits were evaluated. Results: Overall patients showed normal vital signs, minimal adverse events, and relatively less concomitant medication consumption during the study period and at the end of the study, 100% healing was noted among all the study participants in the X-ray investigation. This clearly demonstrates the benefits over the conventional methods. Conclusion: For uncomplicated care of fractures and sports injuries of the limbs, FlexiOH® (Short Arm Immobilizer) technology offers more than just reliable immobilization and has advantages over contemporary plaster and cast bandages. This product is the most advanced orthopaedic immobilization technology and has the potential to be used and adopted worldwide.

Current Trends in Digital Twin Development, Maintenance, and Operation:An Interview Study

Digital twins (DT) are often defined as a pairing of a physical entity and a corresponding virtual entity mimicking certain aspects of the former depending on the use-case. In recent years, this concept has facilitated numerous use-cases ranging from design to validation and predictive maintenance of large and small high-tech systems. Although growing in popularity in both industry and academia, digital twins and the methodologies for developing and maintaining them differ vastly. To better understand these differences and similarities, we performed a semi-structured interview research study with 19 professionals from industry and academia who are closely associated with different lifecycle stages of the corresponding digital twins. In this paper, we present our analysis and findings from this study, which is based on eight research questions (RQ). We present our findings per research question. In general, we identified an overall lack of uniformity in terms of the understanding of digital twins and used tools, techniques, and methodologies for their development and maintenance. Furthermore, considering that digital twins are software intensive systems, we recognize a significant growth potential for adopting more software engineering practices, processes, and expertise in various stages of a digital twin's lifecycle

Current trends in digital twin development, maintenance, and operation:an interview study

Digital twins (DTs) are often defined as a pairing of a physical entity and a corresponding virtual entity (VE), mimicking certain aspects of the former depending on the use-case. In recent years, this concept has facilitated numerous use-cases ranging from design to validation and predictive maintenance of large and small high-tech systems. Various heterogeneous cross-domain models are essential for such systems, and model-driven engineering plays a pivotal role in the design, development, and maintenance of these models. We believe models and model-driven engineering play a similarly crucial role in the context of a VE of a DT. Due to the rapidly growing popularity of DTs and their use in diverse domains and use-cases, the methodologies, tools, and practices for designing, developing, and maintaining the corresponding VEs differ vastly. To better understand these differences and similarities, we performed a semi-structured interview research with 19 professionals from industry and academia who are closely associated with different lifecycle stages of digital twins. In this paper, we present our analysis and findings from this study, which is based on seven research questions. In general, we identified an overall lack of uniformity in terms of the understanding of digital twins and used tools, techniques, and methodologies for the development and maintenance of the corresponding VEs. Furthermore, considering that digital twins are software intensive systems, we recognize a significant growth potential for adopting more software engineering practices, processes, and expertise in various stages of a digital twin’s lifecycle.</p

Projective Ring Line of a Specific Qudit

A very particular connection between the commutation relations of the elements of the generalized Pauli group of a $d$-dimensional qudit, $d$ being a product of distinct primes, and the structure of the projective line over the (modular) ring \bZ_{d} is established, where the integer exponents of the generating shift ($X$) and clock ($Z$) operators are associated with submodules of \bZ^{2}_{d}. Under this correspondence, the set of operators commuting with a given one -- a perp-set -- represents a \bZ_{d}-submodule of \bZ^{2}_{d}. A crucial novel feature here is that the operators are also represented by {\it non}-admissible pairs of \bZ^{2}_{d}. This additional degree of freedom makes it possible to view any perp-set as a {\it set-theoretic} union of the corresponding points of the associated projective line
