Lamun merupakan salah-satu ekosistem yang sangat tinggi produktivitas organiknya, lamun juga memiliki manfaat secara ekonomi dan ekologis. Fungsi lamun tidak banyak dipahami, banyak padang lamun yang rusak oleh berbagai aktivitas manusia terutama penangkapan ikan, pengerukan, penambangan pasir dan sebagainya. Hasil penelitian yang telah dilakukan oleh peneliti sebelumnya dirasa masih kurang untuk dijadikan sebagai rujukan untuk menggambarkan potensi sumberdaya lamun di Kabupaten Pulau Morotai. Olehnya itu perlu kiranya dilakukan penelitian ini sebagai tambahan informasi dan data potensi bagi pengelolaan sumberdaya alam pesisir dan laut terutama ekosistem lamun secara berkelanjutan terutama dari aspek ekologinya. Penelitian ini bertujuan untuk mengetahui komposisi dan keanekaragaman jenis lamun. Penelitian ini dilaksanakan di perairan desa Mandiri Kabupaten Pulau Morotai dimulai pada bulan Januari-Februari 2021 menggunakan metode transek kuadrat. Analisis data indeks ekologi meliputi; komposisi jenis dan indeks keanekareagaman (Shannon-Winner). Hasil penelitian menunjukkan bahwa komposisi jenis lamun paling tinggi persentasenya yaitu Cymodocea rotundata ditemukan disemua stasiun yaitu stasiun I sebesar (94%), stasiun II (84 %) dan stasiun III (72%). Indeks keanekaragaman jenis (H') lamun yang ditemukan pada stasiun I yaitu (0,22), stasiun II (0,58), dan stasiun III yaitu (0,59) menunjukan bahwa nilai indeks keanekaragaman lamun di lokasi penelitian termasuk kategori rendah.

Introduction. Unresectable oral cancer is an urgent and complex problem in modern oncology. Annually, the proportion of patients with stage III–IV is 35 %, and the one-year mortality rate for this pathology reaches 32 %. Patients with advanced oral tumors usually have a negative prognosis and treatment tactics are limited to radiation therapy (RT), chemoradiation therapy, or sequential therapy, including induction chemotherapy (CT). Polymodal therapy for oral cancer is of particular interest in the treatment of pathology in this area.The study objective – to analyze the results of sequential treatment, including induction CT followed by RT and induction CT followed by surgery and RT in patients with unresectable oral cancer (T3–4bN0–3M0).Materials and methods. This retrospective study included 30 patients (11 women and 19 men) with primary non-resectable squamous cell carcinoma of the oral cavity (T3–4bN0–3M0) who received 2–3 courses of induction chemotherapy (CT) with DCF (docetaxel, cisplatin, 5-fluorouracil). Mean patients’ age was 61.2 years. The first treatment stage included induction CT according to the following scheme: docetaxel (75 mg/m2 /day on day 1) + cisplatin (75 mg/m2 /day on day 1) + 5-fluorouracil (1000 mg/m2 /day on days 1–4) repeated every 21 days. Study participants were divided into 2 groups according to their objective response to CT. Patients with resectable residual tumors have undergone surgery (after induction CT) followed by radical radiation therapy (RT) (induction CT + surgery + RT). Patients with non-resectable residual tumors/no objective response/no complete response after induction CT have undergone radical RT (induction CT + RT).Results. The objective response rate (ORR) to induction CT was 66.6 % (20 / 30). Five out of thirty patients (16.7 %) received no subsequent therapy: 3 individuals developed grade III–IV adverse events, while 2 individuals had progressive disease. One-third of patients (10 / 30; 33.3 %) had surgery followed by RT. Half of patients (15 / 30; 50 %) received RT after induction CT. The two-year relapse-free survival rates in the groups of induction CT + surgery + RT and induction CT + RT was 14 and 16 %, respectively (p = 0.49). The two-year overall survival rates in the same groups were 44 and 38 %, respectively (р = 0.74).Conclusion. Resectability was achieved in 33.3 % (10 / 30) of patients with initially unresectable oral cancer after induction CT. A sequential therapy regimen, including a surgical stage after induction CT, did not demonstrate a statistically significant increase in overall and disease-free survival rates. Sequential multimodal treatment of common oral cancers has some potential, but requires further study to assess its significance.
Using Machine Learning for Explosion Yield Estimation
Authors: Stroujkova Anastasia , Leidig Mark 
Published: February 2022

ABSTRACT
We developed a machine learning approach to estimate an explosion yield and height-of-burst or depth-of-burial (HOB or DOB) using a combination of seismic ground-motion and acoustic measurements. The technique employs artificial neural networks (ANNs) with Bayesian regularization suitable for small datasets to reduce the potential for overfitting and improve the network generalization. Using data from multiple explosion experiments conducted in various rock types, we investigated the effect of different seismic and acoustic measurement methods combined with estimated seismic velocity on the yield and the scaled HOB or DOB estimates. The training dataset for the ANN comprised data from 42 explosions conducted in various media at different HOB or DOB. Two additional explosions were used for the method validation. The input features included seismic and acoustic amplitudes, peak frequency, positive phase duration, and the apparent seismic velocity. The presented approach is not limited to a single lithology. Instead, it uses a diverse set of parameters, such as apparent seismic velocity and P-wave peak frequency, to implicitly identify the medium properties within the data-driven framework. Incorporating these parameters resulted in significant improvement of the method performance for both scaled depth and yield estimates. The root mean square error of the scaled depth estimate is on the order of 0.1  m/kg1/3. For the yield estimate, the mean absolute percentage error is less than 10% for both training and validation datasets. The main challenge of using machine learning for yield estimate is a small number of calibration explosions with known yields available for the ANN training. In the future, the developed approach can be further improved by training the ANNs with larger datasets, as more explosion data become available.

La Red Avispa es una lectura periférica sobre el sistema de inteligencia cubano. Partimos del interrogante que guía el presente artículo ¿Cómo se configuró una antítesis de la inteligencia cubana sobre la estadounidense capaz de mantener el establecimiento de La Habana a principios de la década de 1990? Así, nuestra hipótesis se configura a partir de la película La Red Avispa, en la cual se puede leer la estrategia de inteligencia cubana como garante de supervivencia sobre las presiones de Washington en la Guerra Fría, para eso se valió de operaciones directas en territorio estadounidense para infiltrarse en los grupos anticastristas y neutralizar ataques sobre la Isla. Desde el realismo periférico encontramos que, la estrategia de inteligencia de Cuba fue por las consecuencias de una asimetría extrema relevante. Gracias a la presión de Estados Unidos, la Isla tuvo que diseñar modelos estratégicos alternativos para no subsumirse en la geopolítica asimétrica. La Red Avispa, materializa una herramienta periférica para garantizar la pervivencia del régimen de Castro en la década de 1990.
De tal manera, desde el marco del realismo periférico, encontramos que las dimensiones globales se representan en actores que asumen un rol de la siguiente manera: 1. Los forjadores de normas, 2. Los tomadores de normas y, 3. Los rebeldes. Entonces, Cuba asume el último de estos puntos.
Prevalence and correlates of relapse in adult male patients with alcohol dependence: a cross sectional study conducted in a tertiary care hospital in Northern India
Authors: Kumar Prashant , Thadani Anupriya 
Published: February 2022

Background: Relapse to alcohol dependence after successful detoxification and rehabilitation is a public health concern worldwide. Although the burden of alcohol dependence is massive in the Indian subcontinent, very little is known about the causes of relapse among patients treated for alcohol abuse. Hence, this study was designed to evaluate the prevalence and factors associated with relapse in patients of alcohol dependence disorder.Methods: 50 male patients diagnosed with alcohol dependence (according to ICD-10 criteria) who attended both in-patient and out-patient outpatient department (OPD) of a tertiary care hospital were included in our study. Severity of Alcohol Dependence Questionnaire (SADQ) for severity of alcohol dependence, Presumptive Stressful Life Events Scales (PSLES) and relapse precipitant inventory were used for correlation of factors responsible for relapse amongst these alcohol abusers after informed consent and acquiring socio-demographic details.Results: Out of 50 patients enrolled in the study as per the International Classification of Diseases 10th revision Diagnostic Criteria for Research (ICD-10 DCR), a majority (92%) were Hindus, 60% belonging to the rural background. Family history of alcohol dependence was found to be present among 46% patients, and a majority had moderate to severe alcohol dependence. Craving for alcohol was found to be the most common cause of relapse amongst these, and 72% patients showed moderate to severe stress on the PSLES scale.Conclusions: Alcohol consumption is emerging as a major public health problem in India. Regular follow up with family, peer and social support are essential along with vocational rehabilitation to prevent relapse. Multi-centric scientific community-based research studies have to be conducted in various individual states to understand the problem better. There is a dire need for various policymakers, media, professionals and society to come together and create awareness about the consequences of chronic alcohol through sensitization programmes and health education campaigns.

Probabilistic Reserves Categorization Using Percentiles of a Single Probability Distribution
Authors: Mian M. A. 
Published: February 2022

Summary
Petroleum reserves assessment is a routine exercise performed by every oil and gas company. The reserves estimation could be achieved using deterministic or probabilistic methods. Depending on the type of data available, different assumptions and data are used at various stages of the assessment throughout the E&P life cycle (i.e., exploration, appraisal, development, depletion, and so on). The accuracy of the reserves estimate is highly dependent on the amount and quality of data available and experience of the evaluator. The estimates become more accurate and refined as more and more data become available.
The objective of this paper is to urge the industry to rethink the terminology used for categorizing probabilistic reserves (P90, P50, and P10) using a single probability distribution. As a routine practice, we consider 1P = P90 = proved reserves, 2P = P50 = proved + probable reserves, and 3P = P10 = proved + probable + possible reserves. The reserves categories depend on the range of uncertainty as shown in the Petroleum Resources Classification Framework of the Petroleum Resources Management System (PRMS). It is shown here that P50 (or mean/expected value) of each reserve category is a more robust and logical value to be used for categorizing reserves.
The P90 and P10 demonstrate confidence levels of a certain probability distribution, which is owing to the standard deviation (proxy for uncertainty) of the specific distribution and not the range of uncertainty. The range in uncertainty is assessed from varying standard deviations from more than one probability distribution. Therefore, the use of P90 and P10 for reserves categorization contradicts the x-axis title of the Petroleum Resources Classification Framework in the PRMS. The P90, P50, and P10 from a single probability distribution with a single standard deviation will have the same uncertainty (not range of uncertainty). The difference between P90 and P10 is also owing to this single standard deviation. Some examples are presented in this paper to show this and to show that P50 (or mean) with its corresponding standard deviation (indication of uncertainty) could be more appropriately used to book and categorize reserves. The concept of expected value (EV) is also revisited as this may not be correctly reported in some publications.

Published: February 2022

Abstract
Background: Blunt high-energy trauma increase the risk of associated thoracic and accompanying abdominal organ injuries in chest trauma. A higher overall injury severity has been shown for sternovertebral injuries caused by a flexion-compression mechanism. Literature for a hyperextension-distraction mechanism equivalent to a costal arch fracture combined with a thoracic spinal fracture is sparse. Therefore, we want to show the clinical significance of this entity.Methods: A retrospective analysis of our level-one trauma center collective of severely injured patients was performed. Patients from 2013 to 2019 that involved an Injury Severity Score (ISS) ≥16 were screened for the combined thoracovertebral injury entity and analyzed concerning its accident mechanism, the injury spectrum, and the clinical course.Results: The thoracovertebral injury entity is rare. Three male patients (50–65 years old) with ISS of 57, 41, and 20 could be observed from over 1000 severely injured. All patients suffered from high-energy trauma and from tearing of the thoracic vertebrae regions 7–9. The costal arch was torn in the anterior area. All cases showed a posterolateral serial rib fracture, a traumatic intercostal pulmonary hernia, and an avulsion of the diaphragm. Two patients sustained further life-threatening injuries, such as severely bleeding avulsion to the azygos vein and a rupture of the spleen. The physicians performed exploratory thoracotomy, closure of the pulmonary hernia, re-fixation of the diaphragm and angle-stable plate osteosynthesis of the fractured ribs, including the costal arch. The spine was fixed dorsally using a screw-rod system. The patients were discharged home with independent mobility and without neurological damage. Conclusions: This thoracovertebral injury entity is associated with high overall injury severity and life-threatening thoracoabdominal injuries. Injuries to the costal arch can act as an indicator of severe trauma. They should be detected thorough clinical examination and assessment of the trauma CT in the soft tissue window.

Abstract
Background
The prevention of violence against children and youth in Rwanda has often been challenged by the lack of data. To solve that challenge, a national survey on violence was done in 2015-2016 among female and male children and youth aged 13-24. Data from that national survey were used to assess prevalence and predictors of physical violence(PV) against children and youth in Rwanda.
Methods
A nationally representative sample of 2,159 respodents from the Rwanda survey was analyzed. Descriptive statistics assessed the prevalence of PV against children and youth; and logistic regression models investigated predictors of physical violence in that population.
Results
Over two in ten children and youth (23.4%, 95% CI [21.2-25.8]) reported experiences of any form of PV in the last twelve months before the survey. Reported PV was two times higher (15.7, 95% CI [13.7-17.9]) in children and youth attending school than in those not attending school (7.7%, 95% CI [6.4-9.2]); and the likelihoods of reporting PV were higher (aOR: 2.0, 95% CI [1.5-2.6]) among children and youth attending school than in those not attending school.
Conclusions
There is a need to increase efforts in preventing violence against children and youth happening around school in Rwanda.
The Flexibility of Home Away Pattern Sets

Published: February 2022

Abstract
A popular approach to construct a schedule for a round-robin tournament is known as first-break, then-schedule. Thus, when given a Home Away Pattern (HAP) for each team, which specifies for each round whether the team plays a home game or an away game, the remaining challenge is to find a round for each match that is compatible with both team's patterns. When using such an approach, it matters how many rounds are available for each match: the more rounds are available for a match, the more options exist to accommodate particular constraints. We investigate the notion of flexibility of a set of HAPs, and introduce a number of measures assessing this flexibility. We show how the so-called Canonical Pattern Set (CPS) behaves on these measures, and, by solving integer programs, we give explicit values for all single-break HAP-sets with at most 16 teams.

Abstract
BackgroundThe aim of this study is to describe the clinical characteristics of patients with infective endocarditis (IE) due to non-HACEK Gram-negative bacilli (NGNB) and the risk factors associated with mortality in a large multicentre cohort.MethodsThis prospective observational study included consecutive patients with definitive IE diagnosed according to the modified Duke criteria in Brazil between 2006 and 2019. Patients with blood or heart valve cultures positive with NGNB were identified and studied.ResultsOf 1154 adult patients with definite IE enrolled, 38 (3.29%) had IE due to NGNB. Median age was 57 (IQR, 43-69) years. Most common etiologies were Pseudomonas aeruginosa and Klebsiella spp. (8 episodes, 21% each). IE was associated with a higher prevalence of embolic events 21/38(72.4%). Chronic renal failure 18/38(44.7%), prosthetic valves 19/38(50%) and device-related IE 6/8(15.8%) were common. Recent healthcare exposure was found in 52.6% and a central venous catheter (CVC) in 13/38(34.2%). Overall mortality was 19/38(50%). Indwelling CVC (OR 5.93; 95% CI, 1.29 to 27.3; p = 0.017), haemodialysis (OR 16.2; 95% CI, 1.78 to 147; p = 0.008) and chronic kidney disease (OR 4.8; 95% IC, 1.2 to 19.1, p = 0.049) were identified as risk factors associated with mortality, but not multidrug-resistant microorganisms.ConclusionsThe rate of IE due to NGNB was similar to that in previous studies. Enterobacterales and P. aeruginosa were the most common etiologies. NGNB IE was associated with the presence of central venous catheters, prosthetic valves, intracardiac devices and haemodialysis and had a high mortality rate.
