Evaluation of nutritional values of smoke cured riverine and marine hilsa (Tenualosa ilisha; Hamilton, 1882)

Present study was conducted to evaluate nutritional values of smoked hilsa fish (Tenualosa ilisha; Hamilton, 1882) in relation to its raw condition. Smoking is one of the processes of fish preservation from ancient period of our country. The nutrients values of the hilsa from two different regions were significantly (p < 0.05) varied. The nutritional values were different before and after processing of hilsa. Riverine hilsa contains relatively more moisture (56.45 ± 0.51%) and protein (15.98 ± 0.50%) than marine hilsa. Fat (16.18 ± 0.45%) and salt (1.92 ± 0.18%) contents are higher in marine hilsa; whereas ash (8.34 ± 0.35%) content was higher in riverine hilsa. Minerals like iron (4.72 ± 0.08 mg/100 g) and calcium (481.77 ± 6.20 mg/100g) remain in large amount on marine hilsa but phosphorus (115.73 ± 4.36 mg/100 g) content remain high level in riverine hilsa. In addition, the protein (raw condition, 19.54 ± 0.47%, riverine; 17.12 ± 0.42%, marine and smoked condition, 29.64 ± 0.41%, riverine; 28.51 ± 0.51%, marine) and fat (raw condition, 16.41 ± 0.46%, riverine; 20.07 ± 0.39%, marine and smoked condition, 20.71 ± 0.47%, riverine; 23.31 ± 0.47%, marine) content were higher in abdominal region of riverine and marine hilsa both raw and smoked condition than head region (protein in raw condition, 11.21 ± 0.51%, riverine; 10.51 ± 0.53%, marine and smoked condition, 17.14 ± 0.42%, riverine; 15.69 ± 0.4%, marine; fat in raw condition, 9.04 ± 0.45%, riverine; 11.21 ± 0.51%, marine and smoked condition, 12.32 ± 0.44%, riverine; 14.56 ± 0.47%, marine) and caudal region (protein in raw condition17.21 ± 0.52%, riverine; 15.22 ± 0.66%, marine and smoked condition, 27.68 ± 0.44%, riverine; 26.73 ± 0.46%, marine; fat in raw condition, 14.05 ± 0.5%, riverine; 17.28 ± 0.47%, marine and smoked condition, 17.35 ± 0.43%, riverine; 19.18 ± 0.51%, marine).

On Sketching Quadratic Forms

We undertake a systematic study of sketching a quadratic form: given an n x n matrix A, create a succinct sketch sk(A) which can produce (without further access to A) a multiplicative (1+ε)-approximation to xT A x for any desired query x ∈ Rn. While a general matrix does not admit non-trivial sketches, positive semi-definite (PSD) matrices admit sketches of size θ(ε{-2 n), via the Johnson-Lindenstrauss lemma, achieving the "for each" guarantee, namely, for each query x, with a constant probability the sketch succeeds. (For the stronger "for all" guarantee, where the sketch succeeds for all x's simultaneously, again there are no non-trivial sketches.) We design significantly better sketches for the important subclass of graph Laplacian matrices, which we also extend to symmetric diagonally dominant matrices. A sequence of work culminating in that of Batson, Spielman, and Srivastava (SIAM Review, 2014), shows that by choosing and reweighting O(ε{-2 n) edges in a graph, one achieves the "for all" guarantee. Our main results advance this front. For the "for all" guarantee, we prove that Batson et al.'s bound is optimal even when we restrict to "cut queries" x ∈ (0,1}n. Specifically, an arbitrary sketch that can (1+ε)-estimate the weight of all cuts (S, bar S) in an n-vertex graph must be of size Ω(ε{-2 n) bits. Furthermore, if the sketch is a cut-sparsifier (i.e., itself a weighted graph and the estimate is the weight of the corresponding cut in this graph), then the sketch must have Ω(ε{-2 n) edges. In contrast, previous lower bounds showed the bound only for spectral-sparsifiers. For the "for each" guarantee, we design a sketch of size Õ(ε{-1 n) bits for "cut queries" x ∈{0,1}n. We apply this sketch to design an algorithm for the distributed minimum cut problem. We prove a nearly-matching lower bound of Ω(ε{-1 n) bits. For general queries x ∈ Rn, we construct sketches of size Õ(ε{-1.6 n) bits. Our results provide the first separation between the sketch size needed for the "for all" and "for each" guarantees for Laplacian matrices.
Head Impact Magnitude in American High School Football

OBJECTIVES: To describe determinants of head impact magnitudes between various play aspects in high school football. METHODS: Thirty-two high school American football players wore Head Impact Telemetry System instrumented helmets to capture head impact magnitude (linear acceleration, rotational acceleration, and Head Impact Technology severity profile [HITsp]). We captured and analyzed video from 13 games (n = 3888 viewable head impacts) to determine the following play aspects: quarter, impact cause, play type, closing distance, double head impact, player’s stance, player’s action, direction of gaze, athletic readiness, level of anticipation, player stationary, ball possession, receiving ball, and snapping ball. We conducted random intercepts general linear mixed models to assess the differences in head impact magnitude between play aspects (α = 0.05). RESULTS: The following aspects resulted in greater head impact magnitude: impacts during the second quarter (HITsp: P = .03); contact with another player (linear, rotational, HITsp: P < .001); initial head impact when the head is struck twice (linear, rotational, HITsp: P < .001); longer closing distances, especially when combined with a 3-point stance or when being struck in the head (linear: P = .03); the 2-point stance (linear, rotational, HITsp: P < .001); and offensive linemen not snapping the ball compared with those snapping the ball (rotational: P = .02, HITsp: P = .02). CONCLUSIONS: Preventing head impacts caused by contact with another player may reduce head impact magnitude in high school football. Rule or coaching changes that reduce collisions after long closing distances, especially when combined with the 3-point stance or when a player is being struck in the head, should be considered.
Gender and haplotype effects upon hematological manifestations of adult sickle cell anemia

In Africa, the β‐globin gene cluster haplotype may be associated with variation of Hb F levels in subjects with sickle cell anemia (SS). These observations have not yet been conclusively confirmed in SS out of Africa, perhaps because of small sample sizes, the predominance of haplotype heterozygotes, and diverse influences, including gender, upon Hb F levels.
Punishment insensitivity and impaired reinforcement learning in preschoolers.

BACKGROUND Youth and adults with psychopathic traits display disrupted reinforcement learning. Advances in measurement now enable examination of this association in preschoolers. The current study examines relations between reinforcement learning in preschoolers and parent ratings of reduced responsiveness to socialization, conceptualized as a developmental vulnerability to psychopathic traits. METHODS One hundred and fifty-seven preschoolers (mean age 4.7 ± 0.8 years) participated in a substudy that was embedded within a larger project. Children completed the 'Stars-in-Jars' task, which involved learning to select rewarded jars and avoid punished jars. Maternal report of responsiveness to socialization was assessed with the Punishment Insensitivity and Low Concern for Others scales of the Multidimensional Assessment of Preschool Disruptive Behavior (MAP-DB). RESULTS Punishment Insensitivity, but not Low Concern for Others, was significantly associated with reinforcement learning in multivariate models that accounted for age and sex. Specifically, higher Punishment Insensitivity was associated with significantly lower overall performance and more errors on punished trials ('passive avoidance'). CONCLUSIONS Impairments in reinforcement learning manifest in preschoolers who are high in maternal ratings of Punishment Insensitivity. If replicated, these findings may help to pinpoint the neurodevelopmental antecedents of psychopathic tendencies and suggest novel intervention targets beginning in early childhood.
Taxi dispatching via Global Positioning Systems

This paper empirically examines taxi dispatch operations via Global Positioning Systems (GPS) by three taxi companies. The implementation of GPS technology has radically changed the traditional approach to taxi fleet management. In comparison to the radio-paging systems used previously, the satellite-based dispatch systems have considerably enhanced the accuracy, communications, and productivity of taxi operations. However, variables associated with human-system interfaces and operational environments should be taken into account in order to achieve the full capacity of the systems. Furthermore, the reengineering of operations and the training of end-users are vital to the improvement of service quality and the development of sophisticated public transport systems.
River monitoring from satellite radar altimetry in the Zambezi River basin

Satellite radar altimetry can be used to monitor surface water levels from space. While current and past altimetry missions were designed to study oceans, retracking the waveforms returned over land allows data to be retrieved for smaller water bodies or narrow rivers. The objective of this study is the assessment of the potential for river monitoring from radar altimetry in terms of water level and discharge in the Zambezi River basin. Retracked Envisat altimetry data were extracted over the Zambezi River basin using a detailed river mask based on Landsat imagery. This allowed for stage measurements to be obtained for rivers down to 80 m wide with an RMSE relative to in situ levels of 0.32 to 0.72 m at different locations. The altimetric levels were then converted to discharge using three different methods adapted to different data-availability scenarios: first with an in situ rating curve available, secondly with one simultaneous field measurement of cross-section and discharge, and finally with only historical discharge data available. For the two locations at which all three methods could be applied, the accuracies of the different methods were found to be comparable, with RMSE values ranging from 4.1 to 6.5% of the mean annual in situ gauged amplitude for the first method and from 6.9 to 13.8% for the second and third methods. The precision obtained with the different methods was analyzed by running Monte Carlo simulations and also showed comparable values for the three approaches with standard deviations found between 5.7 and 7.2% of the mean annual in situ gauged amplitude for the first method and from 8.7 to 13.0% for the second and third methods.

Effect of fluoride prophylactic agents on the surface topography of NiTi and CuNiTi wires.

AIM The aim of this study was to see the effect of topical fluoride on surface texture on nickel-titanium and copper-nickel-titanium orthodontic archwires. MATERIALS AND METHODS Preformed rectangular NiTi and CuNiTi wires were immersed in in fluoride solution and artificial saliva (control) for 90 minutes at 37°C. after immersion optical microscope was used to see the fluoride effect on the wire topography. RESULTS The acidulated fluoride agents appeared to cause greater corrosive effects as compared to the neutral fluoride agents. CONCLUSION The result suggest that using topical fluoride agents leads to corrosion of surface topography indirectly affecting the mechanical properties of the wire that will lead to prolonged orthodontic treatment. CLINICAL SIGNIFICANCE The use of topical fluoride agents has to be limited in patients with prolonged orthodontic treatment as it causes the corrosion of the NiTi and CuNiTi wires.

Abstract This paper delves into the factors which determine the attractiveness of regions in Europe for migrants. Contrary to the literature on the US which has increasingly focused on the role of amenities, existing research in Europe tends to highlight the predominance of economic conditions as the main drivers of migration. Differentiating between economic, socio-demographic and amenity-related territorial features, we examine the appeal of various regional characteristics for migrants by analyzing net migration data for 133 European regions between 1990 and 2006. Our results show that, in addition to economic, human capital-related and demographic aspects, network effects and – in contrast to existing literature – different types of regional amenities exert an important influence on the relative attractiveness of sub-national territories across the European Union (EU). Our findings therefore indicate that locational choices in Europe may be much more similar to place-based preferences in the US than originally thought.
Longitudinal Pathways of Sexual Victimization, Sexual Self-Esteem, and Depression in Women and Men

Objective: This article presents a longitudinal analysis of the links between sexual assault victimization, depression, and sexual self-esteem by examining their cross-lagged paths among both men and women. Method: Male and female college students (N = 2,425) in Germany participated in the study that comprised 3 data waves in their first, second, and third year of university, separated by 12-month intervals. Sexual assault victimization was assessed at Time 1 (T1) since the age of 14 and at Time 2 (T2) and Time 3 (T3) for the last 12 months. Depression and sexual self-esteem were measured at each wave. Results: Random-intercept cross-lagged panel analyses, controlling for individual differences in depression and sexual self-esteem, showed that sexual assault at T1 predicted depression and lower sexual self-esteem at T2, and depression and lower self-esteem at T2 predicted sexual assault victimization at T3. In addition, significant paths were found from T1 depression to T2 sexual assault victimization and from T2 sexual assault victimization to depression at T3. Sexual victimization at T1 was indirectly linked to sexual victimization at T3 via depression at T2. Both depression and sexual self-esteem at T1 were indirectly linked to sexual victimization at T3. The paths did not differ significantly between men and women. Conclusion: Sexual assault victimization was shown to be a risk factor for both depression as a general mental health indicator and lowered sexual self-esteem as a specific outcome in the domain of sexuality. Moreover, depression and sexual self-esteem increased the vulnerability for sexual assault victimization, which has implications for prevention and intervention efforts.
Protein C and protein S deficiencies: similarities and differences between two brothers playing in the same game

Abstract Protein C (PC) and protein S (PS) are vitamin K-dependent glycoproteins that play an important role in the regulation of blood coagulation as natural anticoagulants. PC is activated by thrombin and the resulting activated PC (APC) inactivates membrane-bound activated factor VIII and factor V. The free form of PS is an important cofactor of APC. Deficiencies in these proteins lead to an increased risk of venous thromboembolism; a few reports have also associated these deficiencies with arterial diseases. The degree of risk and the prevalence of PC and PS deficiency among patients with thrombosis and in those in the general population have been examined by several population studies with conflicting results, primarily due to methodological variability. The molecular genetic background of PC and PS deficiencies is heterogeneous. Most of the mutations cause type I deficiency (quantitative disorder). Type II deficiency (dysfunctional molecule) is diagnosed in approximately 5%–15% of cases. The diagnosis of PC and PS deficiencies is challenging; functional tests are influenced by several pre-analytical and analytical factors, and the diagnosis using molecular genetics also has special difficulties. Large gene segment deletions often remain undetected by DNA sequencing methods. The presence of the PS pseudogene makes genetic diagnosis even more complicated. Clin Chem Lab Med 2010;48:S53–66.
Alternative Splicing of Endothelial Fibronectin Is Induced by Disturbed Hemodynamics and Protects Against Hemorrhage of the Vessel Wall

Objective— Abnormally low-flow conditions, sensed by the arterial endothelium, promote aneurysm rupture. Fibronectin (FN) is among the most abundant extracellular matrix proteins and is strongly upregulated in human aneurysms, suggesting a possible role in disease progression. Altered FN splicing can result in the inclusion of EIIIA and EIIIB exons, generally not expressed in adult tissues. We sought to explore the regulation of FN and its splicing and their possible roles in the vascular response to disturbed flow. Approach and Results— We induced low and reversing flow in mice by partial carotid ligation and assayed FN splicing in an endothelium-enriched intimal preparation. Inclusion of EIIIA and EIIIB was increased as early as 48 hours, with negligible increases in total FN expression. To test the function of EIIIA and EIIIB inclusion, we induced disturbed flow in EIIIAB −/− mice unable to include these exons and found that they developed focal lesions with hemorrhage and hypertrophy of the vessel wall. Acute deletion of floxed FN caused similar defects in response to disturbed flow, consistent with a requirement for the upregulation of the spliced isoforms, rather than a developmental defect. Recruited macrophages promote FN splicing because their depletion by clodronate liposomes blocked the increase in endothelial EIIIA and EIIIB inclusion in the carotid model. Conclusions— These results uncover a protective mechanism in the inflamed intima that develops under disturbed flow, by showing that splicing of FN mRNA in the endothelium, induced by macrophages, inhibits hemorrhage of the vessel wall.
A General Formula for the Mismatch Capacity

The fundamental limits of channels with mismatched decoding are addressed. A general formula is established for the mismatch capacity of a general channel, defined as a sequence of conditional distributions with a general decoding metrics sequence. We deduce an identity between the Verdú-Han general channel capacity formula, and the mismatch capacity formula applied to maximum likelihood decoding metric. Furthermore, several upper bounds on the capacity are provided, and a simpler expression for a lower bound is derived for the case of a non-negative decoding metric. The general formula is specialized to the case of finite input and output alphabet channels with a type-dependent metric. The closely related problem of threshold mismatched decoding is also studied, and a general expression for the threshold mismatch capacity is obtained. As an example of threshold mismatch capacity, we state a general expression for the erasures-only capacity of the finite input and output alphabet channel. We observe that for every channel, there exists a (matched) threshold decoder, which is capacity achieving. In addition, necessary and sufficient conditions are stated for a channel to have a strong converse.
Behavioral Manifestations of Dark Personality Narcissism: an Indigenous Study on Indonesian Workers

Narcissism is one of the three traits incorporated in a dark personality, and this trait is described by an individual's tendency to dominate, like to be the center of attention and be self-oriented. Not only in individual cultural cultures, narcissism is also a fertile body in a collective society that upholds social harmony and behaves by values and norms in its group. Judging from these characteristics, it is suspected that there will be differences in the manifestations of narcissism in collective societies such as in Indonesia. Researchers conducted a study us images psychology collaborative descriptive quantitative research design to trace the form of behavioral images of narcissism in a collaborative culture. The sampling technique used was snowball sampling and involved as many as 760 worker respondents in Indonesia. The research findings were then analyzed using percentage descriptive techniques and categorization. This study succeeded in revealing several things, including (1) the positive and negative behavior of selfish individuals in the work environment; (2) the impact on personal and work relationships when dealing with narcissistic individuals in the work environment; (3) the most disliked behavior of narcissistic individuals in the work environment; and (4) how to deal with narcissistic individuals in the work environment.
Effect of methanol extract of Basella alba L. (Basellaceae) on the fecundity and testosterone level in male rats exposed to flutamide in utero

We evaluated the effect of the methanol extract of Basella alba (MEBa) on testosterone level and fecundity/fertility in male rats exposed in utero to flutamide – an androgen receptor antagonist. For this purpose, 1.5‐ and 2.5 ‐month‐old male rats exposed in utero to flutamide were treated with the MEBa (1 mg kg−1) for 2 and 1 month respectively. Five days before the end of treatment, rats were housed with females to assess their fecundity/fertility. Thereafter, rats were sacrificed and blood collected for the quantification of testosterone. Flutamide‐exposed male rats showed a decrease in their ano‐genital distance (AGD, P < 0.05) and were infertile. In normal (methylcellulose‐exposed) animals, MEBa provoked an increase in testosterone level in 1.5‐ (P < 0.008) and 2.5 ‐month‐old rats (P < 0.01) concomitantly with the improvement in their fecundity by 25%. In flutamide‐exposed male rats, MEBa increased testosterone level in 1.5 ‐month‐old rats (P < 0.001) without any effect on their fecundity; while in 2.5‐ month‐old rats, MEBa did not affect the testosterone level but improved fecundity (by 25%) and fertility (P < 0.001). This study demonstrated the positive effect of MEBa to enhance fecundity/fertility in normal male rats and in rats exposed to the antiandrogen flutamide during their foetal life.
