PROTAL Processing of Titanium Alloys as an Alternative to Degreasing and Grit-Blasting Prior to Thermal Spraying
Authors: Coddet C. , Montavon G. , Verdier M. , Costil S. , Barbezat G. 
Published: June 2022

Abstract
Titanium alloys exhibit high specific strength characteristics. They are for this reason widely used by aeronautical engineers mostly to design airframes and gas turbine components. Very often, surface treatments are applied to locally increase the surface properties, especially to obtain a better resistance against wear. Thermal spraying is largely used to manufacture these coatings. This technology requires a specific surface preparation prior to the spraying stage. This surface preparation conventionally consists in surface degreasing and grit-blasting which has some drawbacks, among them a significant decrease of the components fatigue resistance due to the notch-sensitive behavior of these alloys. The PROTAL process consists in combining surface cleaning based on laser ablation to the deposition stage thus avoiding grit-blasting. This paper aims to present an overview of the possibilities offered by this process for the coating of titanium alloys; the criticality of the different processing parameters is studied and discussed.
What is Scanning Probe Microscopy, and How Can it be Used in Failure Analysis?
Authors: Tangyunyong Paiboon , Campbell Ann 
Published: June 2022

Abstract
Scanning probe microscopy (SPM) refers to a suite of techniques that measure the interaction between a fine probe or tip and a sample in contact or close proximity. These interaction measurements allow the study of properties such as topology, magnetic and electric fields, capacitance, temperature, work function, and friction. The information obtained from SPM plays an important role in IC failure analysis.
Case History: Passive Voltage Contrast Technique for In-Line Characterization and Failure Isolation During Development of Deep-Submicron ASIC CMOS
Authors: Liang Victor , Sur Harlan , Bothra Subhas 
Published: June 2022

Abstract
Passive voltage contrast (PVC) has traditionally been used by semiconductor engineers for end-of-line post-mortem analysis. PVC distinguishes between open and short structures and is both nondestructive and noncontact. When applied during process development for in-line characterization, it allows wafers to be examined at multiple points, where electrical probing might not be feasible. This provides feedback on the cumulative effect of the process on critical parameters such as oxide integrity and can reduce development cycle times because wafers do not have to be deprocessed in order to determine the exact location of failures. Two case studies are presented in this article, demonstrating the use of PVC in a process development environment.
SEM for General Purpose Failure Analysis: "Little Used but Very Useful"
Authors: Devaney John R. 
Published: June 2022

Abstract
Scanning electron microscopes can be used to analyze almost anything that conducts electricity and is prone to failure, including relays, coils, inductors, capacitors, resistors, transistors, diodes, IGBTS, MOSFETS, and hybrid circuits. As the author of the article explains, SEMs are one of the most versatile tools for failure analysis if used to the full extent of their capabilities. Their operating modes include emissive imaging, backscattering, voltage contrast, EBIC or specimen current, and conductivity resistive mapping. The author describes each operating mode and presents examples of the various ways they can be used.

Laser Voltage Probe (LVP): A Novel Optical Probing Technology for Flip-Chip Packaged Microprocessors
Authors: Yee Wai Mun , Paniccia Mario , Eiles Travis , Rao Valluri 
Published: June 2022

Abstract
Laser voltage probing (LVP), an IR-based technique, facilitates through-silicon signal waveform acquisition and high frequency timing measurements from active p-n junctions on CMOS ICs. The ICs can be in flip-chip as well as wire-bond packages with backside access to the IC. As the article explains, LVP significantly improves silicon debug and failure analysis throughput time compared to electron-beam probing because it eliminates the need for backside trenching and probe-hole generating operations.

Published: June 2022

OBJECTIVE
Intracerebral hemorrhage (ICH) is a devastating form of stroke with no proven treatment. However, minimally invasive endoscopic evacuation is a promising potential therapeutic option for ICH. Herein, the authors examine factors associated with long-term functional independence (modified Rankin Scale [mRS] score ≤ 2) in patients with spontaneous ICH who underwent minimally invasive endoscopic evacuation.

METHODS
Patients with spontaneous supratentorial ICH who had presented to a large urban healthcare system from December 2015 to October 2018 were triaged to a central hospital for minimally invasive endoscopic evacuation. Inclusion criteria for this study included age ≥ 18 years, hematoma volume ≥ 15 ml, National Institutes of Health Stroke Scale (NIHSS) score ≥ 6, premorbid mRS score ≤ 3, and time from ictus ≤ 72 hours. Demographic, clinical, and radiographic factors previously shown to impact functional outcome in ICH were included in a retrospective univariate analysis with patients dichotomized into independent (mRS score ≤ 2) and dependent (mRS score ≥ 3) outcome groups, according to 6-month mRS scores. Factors that reached a threshold of p < 0.05 in a univariate analysis were included in a multivariate logistic regression.

RESULTS
A total of 90 patients met the study inclusion criteria. The median preoperative hematoma volume was 41 (IQR 27–65) ml and the median postoperative volume was 1.2 (0.3–7.5) ml, resulting in a median evacuation percentage of 97% (85%–99%). The median hospital length of stay was 17 (IQR 9–25) days, and 8 (9%) patients died within 30 days of surgery. Twenty-four (27%) patients had attained functional independence by 6 months. Factors independently associated with long-term functional independence included lower NIHSS score at presentation (OR per point 0.78, 95% CI 0.67–0.91, p = 0.002), lack of intraventricular hemorrhage (IVH; OR 0.20, 95% CI 0.05–0.77, p = 0.02), and shorter time to evacuation (OR per hour 0.95, 95% CI 0.91–0.99, p = 0.007). Specifically, patients who had undergone evacuation within 24 hours of ictus demonstrated an mRS score ≤ 2 rate of 36% and were associated with an increased likelihood of long-term independence (OR 17.7, 95% CI 1.90–164, p = 0.01) as compared to those who had undergone evacuation after 48 hours.

CONCLUSIONS
In a single-center minimally invasive endoscopic ICH evacuation cohort, NIHSS score on presentation, lack of IVH, and shorter time to evacuation were independently associated with functional independence at 6 months. Factors associated with functional independence may help to better predict populations suitable for minimally invasive endoscopic evacuation and guide protocols for future clinical trials.

Published: June 2022

OBJECTIVE
Posthemorrhagic hydrocephalus (PHH) following preterm intraventricular hemorrhage (IVH) is among the most severe sequelae of extreme prematurity and a significant contributor to preterm morbidity and mortality. The authors have previously shown hemoglobin and ferritin to be elevated in the lumbar puncture cerebrospinal fluid (CSF) of neonates with PHH. Herein, they evaluated CSF from serial ventricular taps to determine whether neonates with PHH following severe initial ventriculomegaly had higher initial levels and prolonged clearance of CSF hemoglobin and hemoglobin degradation products compared to those in neonates with PHH following moderate initial ventriculomegaly.

METHODS
In this observational cohort study, CSF samples were obtained from serial ventricular taps in premature neonates with severe IVH and subsequent PHH. CSF hemoglobin, ferritin, total iron, total bilirubin, and total protein were quantified using ELISA. Ventriculomegaly on cranial imaging was assessed using the frontal occipital horn ratio (FOHR) and was categorized as severe (FOHR > 0.6) or moderate (FOHR ≤ 0.6).

RESULTS
Ventricular tap CSF hemoglobin (mean) and ferritin (initial and mean) were higher in neonates with severe versus moderate initial ventriculomegaly. CSF hemoglobin, ferritin, total iron, total bilirubin, and total protein decreased in a nonlinear fashion over the weeks following severe IVH. Significantly higher levels of CSF ferritin and total iron were observed in the early weeks following IVH in neonates with severe initial ventriculomegaly than in those with initial moderate ventriculomegaly.

CONCLUSIONS
Among preterm neonates with PHH following severe IVH, elevated CSF hemoglobin, ferritin, and iron were associated with more severe early ventricular enlargement (FOHR > 0.6 vs ≤ 0.6 at first ventricular tap).
Integrating Accounting and Logistics Strategy in Business Management
Authors: PYLYPENKO О. 
Published: June 2022

The effective business management in adverse economic conditions necessitates the search for ways for integrating business accounting with innovative approaches to business management of material resources, especially the logistics system.
The need to integrate business accounting of material assets with the logistics system is substantiated by giving evidence of the complicating conditions for transportation of material assets in recent years, related, inter alia, with quarantine limitations. It is stressed that the requirements to logistics strategies are increasing along with growing transportation costs, diminishing deposits of natural resources, creating new product lines, setting new criteria for social, technological and environmental dimensions of business activities. It argued that when management staff overlook or ignore the potentials offered by logistics tools for management of material resources or when business accounting has no links with logistics, the impact of management on the purchase of material assets will be less effective.
Theoretical foundations of the integration of business accounting and logistics strategy of transactions with material assets for the achievement of economic security of business activities are highlighted. The principal dimensions for such integration (organizational, methodological, control and protective) and their key components are discussed. Organizational and technical schemes are proposed, aimed at creating a business accounting system integrated with other management functions (planning, economic analysis, control), in order to enhance the orientation of business enterprise on the effectiveness of logistics activities and achievement of economic security. The main objectives of business accounting with respect to logistics costs are determined for the business enterprises implementing the abovementioned approach to organization of logistics management.
Socio-Economic Security of the Region: Methodological Approaches to Evaluation and Achievement
Authors: LUNOVA Т. 
Published: June 2022

The purpose of the article is to form methodological bases for assessing and ensuring socio-economic security of the region. The relevance of the study is due to the fact that the stability and viability of the state largely depends on the level of socio-economic security of its administrative-territorial units.
The article identifies the essence of socio-economic security of the region by studying two categories: social and economic security. The goals and sequence of development of the Program for strengthening the socio-economic security of the region are substantiated. An algorithm for assessing the level of socio-economic security of the region using an integrated indicator is proposed.
The most significant threats to the socio-economic security of the region are characterized, among which are: uneven territorial development of the country; deepening structural disparities in regional labor markets; low level of technology use; deteriorating investment climate; rising unemployment; poverty growth; changing demographic situation and others. A list of indicators of socio-economic security of the region by economic, social and environmental spheres has been formed. As an example, the weights for the selected indicators are determined, as well as their reference or limit values.
It is concluded that in substantiating the directions of strengthening the socio-economic security of the region should take into account both the results of the assessment and the factors that determine its specificity, in particular: geographical location; transit theory; natural resource potential; areas of economic specialization; the level of state support in the region.

Natural Frequency based delamination estimation in GFRP beams using RSM and ANN
Authors: Sreekanth T. G. , Senthilkumar M. , Reddy S. Manikanta 
Published: June 2022

The importance of delamination detection can be understood from aircraft components like Vertical Stabilizer, which is subjected to heavy vibration during the flight movement and it may lead to delamination and finally even flight crash can happen because of that. Any solid structure's vibration behaviour discloses specific dynamic characteristics and property parameters of that structure. This research investigates the detection of delamination in composites using a method based on vibration signals. The composite material's flexural stiffness and strength are reduced as a result of delaminations, and vibration properties such as natural frequency responses are altered. In inverse problems involving vibration response, the response signals such as natural frequencies are utilized to find the location and magnitude of delaminations. For different delaminated beams with varying position and size, inverse approaches such as Response Surface Methodology (RSM) and Artificial Neural Network (ANN) are utilized to address the inverse problem, which aids in the prediction of delamination size and location.
Ascorbic Acid Therapy in Hematological Malignancies - The Current Knowledge and Future Directions
Authors: Lam Wing Kit , Ha Chung Yin , Yip Sze Fai 
Published: June 2022

Ascorbic acid (AA) therapy in cancer treatment has been highly controversial. Despite the lack of high-quality evidence of its efficacy, complementary or alternative medicine practitioners and physicians have used high-dose intravenous AA (IVAA) therapies for cancer or palliative treatment. AA, which was once out of favor in cancer therapy, is being intensely studied due to more knowledge on the pharmacokinetics properties and anti-cancer effects demonstrated in preclinical studies. On the other hand, there has been more understanding of the pathogenesis of hematological malignancies with next-generation sequencing. There is an increasing number of potential targets for therapies, with AA also being one of the candidates that showed examples of success. The potential of AA therapy in both oral and intravenous formulations in hematological malignancies is reviewed in this article to help identify the current knowledge, the unresolved questions, and future research directions.

Published: June 2022

Gangguan Kecemasan umum atau yang biasa disebut GAD (generalized anxiety disorder) merupakan salah satu satu gangguan kecemasan yang dapat ditandai dengan adanya perasaan cemas yang berelebihan, kecemasan ini biasanya terjadi karena penderita terlalu mengkhawatirkan segala hal yang terjadi diwaktu yang akan datang. Kecemasan ini sangat sulit bahkan tidak dapat dikendalkan. Pendeteksian dini terhadap gangguan kecemasan umum dapat di presiksi oleh suatu sistem. Dengan menggunakan algoritma C5.0 sebuah sistem dapat digunakan untuk membangun sebuah aturan keutusan atau rule yang digunakan untuk mendiagnosis atau memrediksi gangguan kecemasan umum. Algoritma C5.0 dapat mengatasi permasalahan secara terstruktur dengan membentuk sebuah pohon keputusan atau decision tree dengan melalui beberapa tahapan yaitu memilih atribut sebagai akar atau root, membuat cabang untuk masing-masing data pada tiap atribut, membagi kasus kedalam cabang, pemangkasan cabang dan mengulangan proses pada masing-masing cabang hingga seluruh kasus pada cabang dapat menghasilkan suatu keputusan yang sesuai untuk mendiagnosis gangguan kecemasan umum.
Pohon keputusan yang terbangun dari sistem ini memiliki nilai akurasi sebesar 95%. Nilai akurasi tersebut dapat berubah sesuai dengan pemilihan data uji dan data latih karena ada setiap data akan menghasilkan aturan dan ohon keutusan yang berbeda-beda.
