Određivanje spola na temelju diskriminantne analize mandibula iz dva hrvatska arheološka nalazišta Determination of Sex by Discriminant Function Analysis of Mandibles From two Croatian Archaeological Sites

Adresa za dopisivanje Marin Vodanović Sveučilište u Zagrebu Stomatološki fakultet Zavod za dentalnu antropologiju Gundulićeva 5 HR-10000 Zagreb, Hrvatska vodanovic@sfzg.hr Sažetak Kako bi se odredio spol, rabe se mnoge morfološke karakteristike i mjerne metode. Ako se određuje samo na temelju lubanja ili fragmentiranih dijelova čeljusti, tada se koriste razlike u obliku i stupnju izraženosti pojedinih lubanjskih morfoloških obilježja. Ovim su se istraživanjem željeli uspostaviti standardi za određivanje spola na temelju fragmentiranih i cjelovitih mandibula iz dvaju hrvatskih arheoloških nalazišta. Na svakoj mandibuli izmjereno je 19 parametara. Prikupljeni podaci deskriptivno su i multifaktorijalno statistički analizirani te je formirano sedam diskriminantnih funkcija. Diskriminantna funkcija koja je uključivala devet varijabli izmjerenih na mandibulama, omogućila je određivanje spola s pouzdanošću od 92,06%. Utvrđeno je da su dužina korpusa mandibule (muškarci 88,34 ± 4,67 mm; žene 81,41 ± 3,04 mm), mandibularni kut (muškarci 118,47 ± 6,16°; žene 125,63 ± 5,37°) i minimalna širina ramusa (muškarci 31,26 ± 2,94 mm; žene 28,36 ± 2,15 mm) varijable koje omogućuju najbolje spolno razlikovanje. Rezultati istraživanja pokazali su da se mandibula može koristiti za određivanje spola, kao što je to već zaključeno u drugim sličnim istraživanjima.

Relapse prevention in pediatric patients with ADHD treated with atomoxetine: a randomized, double-blind, placebo-controlled study.

OBJECTIVE
Attention-deficit/hyperactivity disorder (ADHD) is typically treated over extended periods; however, few placebo-controlled, long-term studies of efficacy have been reported.


METHOD
In a global multicenter study, children and adolescents who responded to an initial 12-week, open-label period of treatment with atomoxetine, a nonstimulant treatment for ADHD, were randomized to continued atomoxetine treatment or placebo for 9 months under double-blind conditions.


RESULTS
A total of 416 patients completed acute atomoxetine treatment and were randomized. At end point, atomoxetine was superior to placebo in preventing relapse defined as a return to 90% of baseline symptom severity (proportion relapsing: atomoxetine 65 of 292 [22.3%], placebo 47 of 124 [37.9%], p =.002). The proportion of patients with a 50% worsening in symptoms post-randomization was also lower on atomoxetine (atomoxetine 83 of 292 [28.4%], placebo 59 of 124 [47.6%], p <.001). Compared with patients in the placebo group, atomoxetine-treated patients had superior psychosocial functioning at end point. Discontinuations for adverse events were low in both groups, and tolerability was similar to that observed in acute treatment trials.


CONCLUSIONS
In patients who responded favorably to 12 weeks of initial treatment, atomoxetine was superior to placebo in maintaining response for the ensuing 9 months. This result supports the value of maintenance treatment with atomoxetine in patients with ADHD who respond to initial treatment.
Intravascular ultrasound findings of early stent thrombosis after primary percutaneous intervention in acute myocardial infarction: a Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction (HORIZONS-AMI) substudy.

BACKGROUND
Small stent area and residual inflow/outflow disease have been reported as the strongest intravascular ultrasound (IVUS) predictors of early stent thrombosis (ST) in patients with stable angina. IVUS predictors of early ST in patients with acute myocardial infarction have not been studied.


METHODS AND RESULTS
In the Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction (HORIZONS-AMI) study, a formal substudy included poststent and 13-month follow-up IVUS at 36 centers. Twelve patients with baseline IVUS who had definite/probable early ST ≤30 days after enrollment were compared with 389 patients without early ST. Significant residual stenosis was a lumen area <4.0 mm(2) with ≥70% plaque burden ≤10 mm from each stent edge. Significant edge dissection was more than medial dissection with lumen area <4 mm(2) or dissection angle ≥60°. Randomization to bivalirudin (P=0.29) or paclitaxel-eluting stent (P=0.74) was not related to early ST. Minimum lumen area was smaller in patients with versus without early ST (4.4 mm(2) [3.6, 6.9] versus 6.7 mm(2) [5.3, 8.0], respectively, P=0.014). Minimum lumen area <5 mm(2), significant residual stenosis, significant stent edge dissection, and significant tissue (plaque/thrombus) protrusion (more than the median that narrowed the lumen to <4 mm(2)) were more prevalent in patients with early ST, but significant acute malapposition (more than the median) was not. Overall, 100% of patients with early ST had at least 1 of these significant features: minimum lumen area <5 mm(2), edge dissection, residual stenosis, or tissue protrusion versus 23% in patients without early ST (P<0.01).


CONCLUSIONS
Smaller final lumen area and inflow/outflow disease (residual stenosis or dissection) but not acute malapposition were related to early ST after acute myocardial infarction intervention.

Anatomic anterior cruciate ligament (ACL) reconstruction: a global perspective. Part 1

In August 2011, orthopaedic surgeons from more than 20 countries attended a summit on anatomic anterior cruciate ligament (ACL) reconstruction. The summit offered a unique opportunity to discuss current concepts, approaches, and techniques in the field of ACL reconstruction among leading surgeons in the field. Five panels (with 36 panellists) were conducted on key issues in ACL surgery: anatomic ACL reconstruction, rehabilitation and return to activity following anatomic ACL reconstruction, failure after ACL reconstruction, revision anatomic ACL reconstruction, and partial ACL injuries and ACL augmentation. Panellists’ responses were secondarily collected using an online survey. Thirty-six panellists (35 surgeons and 1 physical therapist) sat on at least one panel. Of the 35 surgeons surveyed, 22 reported performing “anatomic” ACL reconstructions. The preferred graft choice was hamstring tendon autograft (53.1 %) followed by bone-patellar tendon-bone autograft (22.8 %), allograft (13.5 %), and quadriceps tendon autograft (10.6 %). Patients generally returned to play after an average of 6 months, with return to full competition after an average of 8 months. ACL reconstruction “failure” was defined by 12 surgeons as instability and pathological laxity on examination, a need for revision, and/or evidence of tear on magnetic resonance imaging. The average percentage of patients meeting the criteria for “failure” was 8.2 %. These data summarize the results of five panels on anatomic ACL reconstruction. The most popular graft choice among surgeons for primary ACL reconstructions is hamstring tendon autograft, with allograft being used most frequently employed in revision cases. Nearly half of the surgeons surveyed performed both single- and double-bundle ACL reconstructions depending on certain criteria. Regardless of the technique regularly employed, there was unanimous support among surgeons for the use of “anatomic” reconstructions using bony and soft tissue remnant landmarks. V.
Theory and Performance Evaluation of Group Coding of RFID Tags

Radio frequency identification (RFID) is an automatic identification technology which identifies physical objects individually according to their unique identifiers (ID) recorded in each RFID tag. Many business processes require the integrity verification of a group of objects in addition to individual object identification. This paper proposes “group coding” of RFID tags with which we can verify the integrity of groups of objects by writing parity check data to the memory of RFID tags. It was revealed by simulations and experiments that we could determine the number of missing RFID tags up to 10 with accuracy over 99% when we write 96 bits of the checksum data to 20 RFID tags. The whole duration of group decoding measured in the experiment was approximately 2 to 3 s. The time to compute group encoding and decoding was in the order of several milliseconds and thus negligible. The RFID inventory accounts for the majority of the duration. Note to Practitioners-Current RFID features fast identification of many physical objects. However, the integrity check of a group of objects is usually done by looking up a packaging list or a shipment list in EDI, which requires a network connection. Our proposed “group coding” of RFID tags can perform the group integrity check without a network connection. In addition, when the integrity of the group is infringed, the group coding can determine the number of RFID tags missing from the group. These features of group coding can reduce the cost of looking up shipment lists and locate missing RFID tags. The accuracy of the determination is controlled by adjusting the size of data written in each RFID tag. Adopters of group coding can select the optimal performance of group coding from the requirements of the accuracy and constraints like memory consumption of RFID tags.
Gender Bias Without Borders An Investigation of Female Characters in Popular Films Across 11 Countries GENDER BIAS WITHOUT BORDERS

Women the world over face stark disparities in health, finance, education, politics, and other arenas. Persistent gender inequality may threaten economic growth and/or social progress.1 At the most micro level, discrimination impedes girls and women from achieving their individual hopes and dreams. Through its Millennium Development Goals, the United Nations has championed an increase in equality for women and girls across different sectors by 2015.2 Despite a push to promote females worldwide, one example of where progress remains stagnant is the U.S. film industry.
Decision trees: a recent overview

Decision tree techniques have been widely used to build classification models as such models closely resemble human reasoning and are easy to understand. This paper describes basic decision tree issues and current research points. Of course, a single article cannot be a complete review of all algorithms (also known induction classification trees), yet we hope that the references cited will cover the major theoretical issues, guiding the researcher in interesting research directions and suggesting possible bias combinations that have yet to be explored.
Prospective Association Between the Dietary Inflammatory Index and Cardiovascular Diseases in the SUpplémentation en VItamines et Minéraux AntioXydants (SU.VI.MAX) Cohort

BACKGROUND
Cardiovascular diseases (CVD) are the leading cause of death in the world, and diet plays a major role in CVD incidence, especially through lipid oxidation mechanisms. This, in turn, leads to tissue inflammation and formation of atheromatous plaques.


METHODS AND RESULTS
Our objective was to evaluate the association between the inflammatory potential of the diet and the incidence of overall CVD or its subclasses. We included 7743 participants from the Supplémentation en Vitamines et Minéraux AntioXydants (SU.VI.MAX) cohort. All cardiovascular events were recorded using self-reported information or clinical visits, and were validated. The dietary inflammatory index (DII) was computed using repeated 24-hour dietary records (mean=9.5±3.4 records/subject). Hazard ratio and 95% CI for outcomes (CVD and subclasses) were estimated across sex-specific quartiles of the DII using Cox proportional hazard models. A total of 292 cardiovascular events were recorded and validated during an average of 11.4 years of follow-up: 93 myocardial infarctions, 58 strokes, 128 angina pectoris and revascularization interventions, and 13 sudden deaths. When considering CVD subclasses, a diet with pro-inflammatory properties, as expressed by higher DII scores, was significantly associated with a higher risk of myocardial infarction (hazard ratioQuartile 4 versus Quartile 1=2.24, 95% CI: 1.08-4.67). No significant association was observed between the DII score and stroke or both angina pectoris and revascularization intervention.


CONCLUSIONS
A pro-inflammatory diet, as measured by a higher DII score, was prospectively associated with a higher risk of myocardial infarction. Promotion of a diet exhibiting anti-inflammatory properties may help prevent myocardial infarctions.

Biomechanical wall properties of human intracranial aneurysms resected following surgical clipping (IRRAs Project).

BACKGROUND AND PURPOSE
Individual rupture risk assessment of intracranial aneurysms is a major issue in the clinical management of asymptomatic aneurysms. Aneurysm rupture occurs when wall tension exceeds the strength limit of the wall tissue. At present, aneurysmal wall mechanics are poorly understood and thus, risk assessment involving mechanical properties is inexistent. Aneurysm computational hemodynamics studies make the assumption of rigid walls, an arguable simplification. We therefore aim to assess mechanical properties of ruptured and unruptured intracranial aneurysms in order to provide the foundation for future patient-specific aneurysmal risk assessment. This work also challenges some of the currently held hypotheses in computational flow hemodynamics research.


METHODS
A specific conservation protocol was applied to aneurysmal tissues following clipping and resection in order to preserve their mechanical properties. Sixteen intracranial aneurysms (11 female, 5 male) underwent mechanical uniaxial stress tests under physiological conditions, temperature, and saline isotonic solution. These represented 11 unruptured and 5 ruptured aneurysms. Stress/strain curves were then obtained for each sample, and a fitting algorithm was applied following a 3-parameter (C(10), C(01), C(11)) Mooney-Rivlin hyperelastic model. Each aneurysm was classified according to its biomechanical properties and (un)rupture status.


RESULTS
Tissue testing demonstrated three main tissue classes: Soft, Rigid, and Intermediate. All unruptured aneurysms presented a more Rigid tissue than ruptured or pre-ruptured aneurysms within each gender subgroup. Wall thickness was not correlated to aneurysmal status (ruptured/unruptured). An Intermediate subgroup of unruptured aneurysms with softer tissue characteristic was identified and correlated with multiple documented risk factors of rupture.


CONCLUSION
There is a significant modification in biomechanical properties between ruptured aneurysm, presenting a soft tissue and unruptured aneurysms, presenting a rigid material. This finding strongly supports the idea that a biomechanical risk factor based assessment should be utilized in the to improve the therapeutic decision making.
Implementation of Photometric Stereo with General , Unknown Lighting

This report discusses the implementation of the shape recovery in case of four harmonics as described in the paper titled Photometric Stereo with General, Unknown Lighting (Basri, Jacobs, Kemelmacher), 2006. The goal is to recover the harmonic images from a set of number of images of an object taken from the same viewpoint but with different illumination. These harmonic images are then used to infer the surface normal and albedos of the object being imaged. Keywords—photometric stereo; singular value decomposition(SVD); eigenvalue decomposition; albedo; surface normal; Lorentz transformation
Social interaction in online support groups: Preference for online social interaction over offline social interaction

Keywords: Online support group Supportive communication E-health Computer-mediated communication Preference for online social interaction Internet a b s t r a c t The purpose of the current study was to identify potential factors leading to preference for social interaction in online support groups (OSGs) over offline inter action. By identifying such factors, the current study advances understanding of the way patients use the Internet as a supportive resource and integrate support from offline and online relationships. An online survey was conducted with current users of health-r elated OSGs (N = 158). Findings show that those who were dissatisfied with the support they received from their current offline contacts were more likely to prefer social interaction in OSGs. Such a preference was prominent among those who built deeper social relationships in OSGs. Results suggest that some people develop a preference for social inter action in OSGs over offline interaction and use computer -med iated relationships as a possible alternative to offline support networks. Healthcare professionals and users as well as designers of OSGs must acknowledge the limits of online support and caution against the possibility of developing excessive reliance on online support resources. With the rapid growth of Internet and computer-medi ated communication over the last decade, online support groups (OSGs) have become a new venue for social support. Health-relat ed OSGs have proliferated on the Internet and have become an important source for information and support for many people (Turner, Grube, & Meyers, 2001). According to Pew Internet, about 60% of those who search the Internet for health information use online social media (Fox, 2009). In another recent survey, about a third of people diagnosed with chronic health conditions reported visiting OSGs devoted to their health issues (Annenberg National Health Communication Survey, 2008). In these OSGs, patients seek and share information and knowledge about illness and discuss feelings and Many studies have shown the benefits OSGs bring to patients: They feel empowered through the processes of sharing emotions, reading others' experiences, building social relationshi ps, and acquiring information and skills related to illness managemen t and treatment (Barak, Boniel-Nissi m, & Suler, 2008; van Uden-Kraan et al., 2008). Patients also recover and obtain a sense of normalcy by learning how others have coped with similar issues the nature of relationship s formed online is often short-lived because of frequent turnover in membership (Galston, 2000). In many cases, because of …
High throughput in vitro micropropagation of sugarcane (Saccharum officinarum L.) from spindle leaf roll segments: Cost analysis for agri-business industry

High throughput micropropagation (HTM) protocol in sugarcane through direct shoot regeneration comprising five stages, was developed for agri-business industry. The distinction of the protocol lies in direct adventitious shoot regeneration without an intervening callus phase and liberty over the number of subculture passages leading to high rates of synchronous plant production. Stage 0 dealt with selection and maintenance of field-grown stock plants; Stage I marked the initiation of in vitro propagation on culture initiation medium using spindle leaf roll segments from apical tops; Stage II involved five passages (of 14 days each) on shoot multiplication medium followed by one additional passage (of 10 days) on shoot multiplication-cum-elongation medium. The shoot multiplication rates ranged from 4 to 25-fold in CoPb 91 and CoJ 83 cultivars, respectively; Stage III involved in vitro rooting on root induction medium and hardening for 14 days at each step; Stage IV comprised separation of clumps into single plantlets and transfer to soil. The complete plants were produced in 157 days with 97 percent survival rate. The fidelity of the protocol for agri-business industry was tested by producing approximately 0.1 million saleable HTM sugarcane plants in a small scale (150 m2) tissue culture unit. The recurring (energy, labour, media, culture container, transplanting material) and non-recurring (laboratory infrastructure, glasshouse, equipment) parameters accounted for 75.56 and 24.44 percent production costs, respectively. The low-cost options for media, culture containers and transplanting material were incorporated and cost per plant was calculated to be US$ 0.13. The HTM protocol was adopted by two sugar mills, and the HTM plants produced in our tissue culture unit were sold for seed multiplication to eight sugar mills and 430 farmers throughout North India.
Supply chain maturity and performance in Brazil

Purpose – The purpose of the paper is to investigate the relationship between supply chain maturity and performance, with specific references both to the business process orientation maturity model and to the supply chain operation reference model. Design/methodology/approach – Quantitative, survey based research was carried out with 478 Brazilian companies. Statistical analysis combined the use of descriptive statistics and structural equation modeling. Findings – Empirical results indicate a strong and positive statistical relationship between supply chain maturity and performance. The results also suggest that the deliver process maturity has a higher impact on overall performance than the other supply chain processes. Research limitations/implications – Quantifying supply chain maturity and performance is an opportunity for a company to align its performance measurements and process improvement actions with its broader policies and strategies. The use of this approach has been validated in several previous research studies in organizational self-assessment and business management. Practical implications – Maturity models are valuable frameworks for corporate leadership. This study provides solid statistical evidence that a company that has achieved a higher maturity level and implemented the maturity factors also has achieved superior performance. It also validates the application of these specific maturity factors in South America, specifically Brazil. Originality/value – This paper confirms and expands upon earlier research suggesting higher levels of process maturity were related to superior performance. This paper also examines the evolution of performance measurement systems, moving from a traditional approach to a more process oriented perspective by reporting on the origins of maturity models and presenting the main empirical contributions through the use of the business process maturity model and supply chain operation reference model.
