Low space-complexity digit-serial dual basis systolic multiplier over Galois field GF(2m) using Hankel matrix and Karatsuba algorithm

Multiplication is one important finite field arithmetic operation in cryptographic computations. Dual basis multipliers over Galois field GF(2 m ) have been widely applied in this kind of computations because of its advantage of small chip area. Nevertheless, up to date, there are only few methods that can keep balance of low space complexity and low time complexity at the same time. In order to achieve such an efficient aim, this study presents a novel digit-serial dual basis multiplier that is different from existing ones with a modified cut-set method using Karatsuba algorithm as well as Hankel matrix. As a result, the proposed multiplier can save much space and thus be particularly suitable for some hand held devices equipped with only limited resources. The proposed digit-serial dual basis multiplier saves 55% space complexity as compared with existing similar studies with National Institute of Standards and Technology (NIST) suggested values for elliptic curve cryptosystem.
Cardiac ion channel modulation by the hypoglycaemic agent rosiglitazone

The hypoglycaemic thiazolidinedione rosiglitazone is used clinically in the treatment of type 2 diabetes. However, in 2010, information relating to rosiglitazone‐associated increased cardiovascular risk led the European Medicines Agency to recommend suspension of marketing authorizations for rosiglitazone‐containing anti‐diabetes drugs, while the US Food and Drug Administration recommended significant restriction on the agent's use. Two timely studies in this issue of the British Journal of Phrarmacology provide new information regarding modification of cardiac cellular electrophysiology by rosiglitazone. Szentandrássy et al. demonstrate canine ventricular action potential modification and concentration‐dependent suppression of L‐type Ca current and of transient outward and rapid delayed rectifier K currents. Jeong et al. demonstrate concentration‐dependent inhibition of recombinant Kv4.3 channels, providing mechanistic insight into the likely molecular basis of transient outward K current inhibition by the compound. Further studies using diabetic models would be of value to determine whether, in a diabetic setting, rosiglitazone modification of these channels could affect the risk of arrhythmia at clinically relevant drug concentrations.

Clinical Practice Variations in Prescribing Antipsychotics for Patients With Schizophrenia

Few studies have examined the variations among individual physicians in prescribing antipsychotics for schizophrenia. This study examined clinical practice variations in the route and dosage of antipsychotic medication prescribed for inpatients with schizophrenia by 11 different psychiatrists. The sample consisted of 130 patients with a DSM-III-R diagnosis of schizophrenia who had received inpatient care at a state hospital or Veterans Affairs medical center in the southeastern United States in 1992-1993. Mixed-effects regression models were developed to explore the influence of individual physicians and hospitals on route of antipsychotic administration (oral or depot) and daily antipsychotic dose, controlling for patient casemix variables (age, race, sex, duration of illness, symptom severity, and substance-abuse diagnosis). The average daily antipsychotic dose was 1092 ± 892 chlorpromazine mg equivalents. Almost half of the patients (48%) were prescribed doses above or below the range recommended by current practice guidelines. The proportion of patients prescribed depot antipsychotics was significantly different at the 2 hospitals, as was the antipsychotic dose prescribed at discharge. Individual physicians and patient characteristics were not significantly associated with prescribing practices. These data, which were obtained before clinical practice guidelines were widely disseminated, provide a benchmark against which to examine more current practice variations in antipsychotic prescribing. The results raise several questions about deviations from practice guidelines in the pharmacological treatment of schizophrenia. To adequately assess quality and inform and possibly further develop clinical practice guideline recommendations for schizophrenia, well-designed research studies conducted in routine clinical settings are needed.
Cold and heat resistance of five species of Sphagnum

Differences in the resistance of the chlorophyll-containing cells of the branch leaves of five species of the genus Sphagnum L. were revealed by direct freezing and heating. Sphagnum balticum (Russ.) C. Jens. , S. subsecundum Nees and S. teres (Schimp.) Angstr. were shown to be more frost-resistant than S. magellanicum Brid. and S. fuscum (Schimp.) Klinggr. Differences in heat resistance between the mosses studied were smaller than those in cold resistance. However, there was correlation between the two responses. The thermo-resistance of Sphagnum mosses was shown to be strongly affected by environmental conditions.
The significance of RDW in patients with hepatocellular carcinoma after radical resection.

BACKGROUND Red blood cell distribution width (RDW) is a parameter reported in blood routine examination, and has been reported as an inflammatory biomarker. The objective of this study was to investigate the significance of RDW in patients with hepatocellular carcinoma after radical resection. METHOD The relationship between the preoperative serum RDW value and clinic pathologic characteristics was analyzed in 106 HCC patients who underwent curative resection of hepatocellular carcinoma. Kaplan-Meier survival analysis and Cox proportional hazard models were used to examine the effect of RDW on survival. RESULTS The RDW levels were divided into two groups: high RDW (> 14.5%) and low RDW (≤ 14.5%), (n= 28 vs n= 78). The patients with preoperative high levels of RDW had significantly worse survival than those with low RDW (p< 0.05). According to multivariate analysis, high RDW (HR = 1.89, p= 0.002), TNM stage (HR = 1.70, p= 0.019), tumor size (HR = 1.33, p= 0.045), tumor number (HR = 1.42, p= 0.027) and vascular invasion (HR = 1.64, p= 0.009) were independent prognostic factors of OS. CONCLUSIONS Preoperative high levels of RDW are associated with poor survival. It might be an independent prognostic factor in patients with hepatocellular carcinoma.
Intensive care units, communication between nurses and physicians, and patients' outcomes.

BACKGROUND Various factors in hospitals can adversely affect patients' outcomes, including faulty communication between nurses and physicians. Whether specific communication elements (timeliness, accuracy, openness, understanding) can influence adverse outcomes is unknown. OBJECTIVES To determine the relationships between patients' outcomes and (1) nurses' perceptions of elements of communication between nurses and physicians and (2) characteristics of the practice environment. METHODS A cross-sectional survey design was used. Information on ventilator-associated pneumonia, bloodstream infection associated with a central catheter, and pressure ulcers was collected from 25 intensive care units in southeastern Michigan. Simultaneously, 462 nurses in those units (response rate, 53.3%) were anonymously surveyed. The Conditions for Work Effectiveness Questionnaire-II and the Practice Environment Scale of the Nursing Work Index were used to measure characteristics of the practice environment. The Intensive Care Unit Nurse-Physician Questionnaire was used to measure communication between nurses and physicians. Statistical tests included correlation and multiple regression. Analyses were conducted at the unit level. RESULTS Unit response rates varied from 6% to 100%. Together, variability in understanding communication and capacity utilization were predictive of 27% of the variance in ventilator-associated pneumonia. Timeliness of communication was inversely related to pressure ulcers (r= -0.38; P=.06), and workplace empowerment and scores on the Acute Physiology and Chronic Health Evaluation III were positive predictors of ventilator-associated pneumonia (R(2)=0.36; P=. 005). CONCLUSIONS Not all elements of communication were related to the selected adverse outcomes. The connection between characteristics of the practice environment at the unit level and adverse outcomes remains elusive.
Alcohol-induced sexual impotence.

Sexual impotence resulting from prolonged alcohol abuse may persist even after years of sobriety. The authors believe this problem is neither a psychological nor a hormonal defect but is due to the destructive effect of alcohol on the neurogenic reflex arc that serves the process of erection. The damage may be irreversible, accounting for the inability of some men to reattain potency.
Is Marriage Protective for all Children? Cumulative Risks at Birth and Subsequent Child Behavior among Urban Families

Today, 37% of all births are to unmarried mothers (Hamilton, Martin, & Ventura, 2006). This represents a doubling in nonmarital childbearing in the past 25 years. Reducing nonmarital childbearing and promoting marriage among unmarried parents have become major policy concerns because, although the increase in nonmarital births has occurred at all education levels and among all race/ethnic groups, the trends have disproportionately affected lower educated and minority women (Ellwood & Jencks, 2004), which is fueling the growing inequality in this country. A concern is that two very different trajectories have been created for children; one for children born to married parents that is largely advantageous and one for children born to unmarried mothers that is beset with multiple risks.
Morphine withdrawal precipitated by specific mu, delta or kappa opioid receptor antagonists: a c‐Fos protein study in the rat central nervous system

We have recently shown concurrent changes in behavioural responses and c‐Fos protein expression in the central nervous system in both naive and morphine‐dependent rats after systemic administration of the opioid antagonist naloxone. However, because naloxone acts on the three major types of opioid receptors, the present study aimed at determining, in the same animals, both changes in behaviour and c‐Fos‐like immunoreactivity after intravenous injection of selective opioid antagonists, such as mu (β‐funaltrexamine, 10 mg/kg), delta (naltrindole, 4 mg/kg) or kappa (nor‐binaltorphimine, 5 mg/kg) opioid receptor antagonists, in naive or morphine‐dependent rats. In a first experimental series, only β‐funaltrexamine increased c‐Fos expression in the eight central nervous system structures examined, whereas no effect was seen after naltrindole or nor‐binaltorphimine administration in naive rats. These results suggest a tonic activity in the endogenous opioid peptides acting on mu opioid receptors in normal rats. A second experimental series in morphine‐dependent rats showed that β‐funaltrexamine had the highest potency in the induction of classical signs of morphine withdrawal syndrome, as well as the increase in c‐Fos expression in the 22 central nervous system structures studied, suggesting a major role of mu opioid receptors in opioid dependence. However, our results also demonstrated that naltrindole and, to a lesser extent, nor‐binaltorphimine were able to induce moderate signs of morphine withdrawal and relatively weak c‐Fos protein expression in restricted central nervous system structures. Therefore, delta and kappa opioid receptors may also contribute slightly to opioid dependence.
Plasma Cell Myeloma Associated with Epstein-Barr Virus Infection in an 11-Year-Old Girl

Multiple myeloma is extremely rare in children and represents fewer than 1% of all patients with myeloma. We report a case of multiple myeloma in an 11-year-old girl, who presented with a well-differentiated immunoglobulin A/kappa plasmacytoma at the base of the skull at 9 years of age; at that time, the bone marrow biopsy was negative. Two years later, the patient experienced generalized bone pain with multiple lytic bone lesions that affected the skull, long bones, ribs, and clavicle. The bone marrow biopsy showed a well-differentiated (Marschalko-type) multiple myeloma that was positive for CD138 and immunoglobulin A, with kappa light chain restriction. Interestingly, the Epstein-Barr virus (EBV) was detected by in situ hybridization for EBV-encoded RNA (EBER) in the majority of the neoplastic cells from both biopsy specimens. The patient responded favorably to treatment with dexamethasone, thalidomide, and zoledronic acid and is scheduled for bone marrow transplantation.
Multiple access with attention-based tournaments for monitoring over wireless networks

Wireless sensor networks for control and moni- toring applications introduce critical constraints on the design of multiple access schemes. Controlling dynamic processes requires that priority must be given to critical systems for the use of the wireless medium. Tournaments in the medium access control (MAC) layer are presented as a way to evaluate priorities and assign channel resources in a distributed manner. The priorities are dynamically assigned based on the attention that each data packet requires. A mathematical formulation of attention is presented together with the corresponding performance analysis of the multiple access scheme. Priorities based on the attention emphasize the information content in the data to be transmitted and the related process dynamics. It is shown that under certain conditions, the performance of this distributed scheme converges to a scheduling policy based on minimizing the per-sample variance of the error in the estimates obtained with limited communication resources. Sustainable data rates for a cluster of linear processes are also derived.

Mecanismos funcionales de la adaptación específica a estímulos y la detección de la novedad en el cerebro auditivo

[ES]En resumen, esta Tesis Doctoral demuestra que la SSA es un mecanismo presente en el cerebro del mamifero y que no se trata de un artefacto generado por la anestesia. Muestra ademas que la SSA es un mecanismo que puede explicarse perfectamente, a nivel subcortical, por el modelo de los canales de frecuencia. La existencia de controles de ganancia consecutivos ejercidos por el sistema GABAergico sugiere tambien la presencia de varios niveles jerarquicos de procesamiento que ayudan a refinar y reducir la informacion redundante. En conjunto, la SSA parece ser un mecanismo que actua como filtro preatentivo reduciendo las senales sensoriales irrelevantes, ayudando a los animales a presentar respuestas adecuadas para facilitar su supervivencia.
HEMODYNAMIC EFFECTS OF BLOOD TRANSFUSION IN CHRONIC ANEMIA

IN patients with severe chronic anemia, whether or not it is amenable to treatment with specific therapy, the administration of blood transfusions is often necessary to provide immediate symptomatic improvement and to prevent potential irreversible anoxic damage to tissues. The slow administration of packed red blood cells with the patient in a semiupright position is often well tolerated. Not infrequently, however, congestive heart failure may supervene during or after the transfusion.2 , 3 The hematology literature is replete with caution against transfusion, especially in patients with pernicious anemia, and a number of fatal cases have been observed with pulmonary edema found at .
Playing with Chance: On Random Generation in Playable Media and Electronic Literature

Randomly generated content poses problems for theories of digital art: such content is resistant to structural theories, which can only provide templates, and one cannot assume a shared text for close analysis. Instead of reaching fixed endings, such works also tend to be of indefinite length or at least suggest indefinite possible combinations. I argue that the impact of such works can instead be found in how one attempts to work through their underlying grammar, based on limits in the algorithms that generate the content — not those limits themselves, but how their outlines come to be known. Repetitively iterating through these works simultaneously upholds the chance nature of the epiphenomenal occurrences while also illustrating the sameness of the underlying algorithm over time, creating a future-oriented interpretive arc. I examine two works that play off of this technique in different ways: Nick Montfort’s Taroko Gorge, a poetry generator which uses random generation to distill the essence of its object’s possibility, and the action role-playing game Torchlight, which attempts to elevate chance beyond a mere gameplay mechanic and toward an ethic.
Age-related, sport-specific adaptions of the shoulder girdle in elite adolescent tennis players.

CONTEXT Tennis requires repetitive overhead movements that can lead to upper extremity injury. The scapula and the shoulder play a vital role in injury-free playing. Scapular dysfunction and glenohumeral changes in strength and range of motion (ROM) have been associated with shoulder injury in the overhead athlete. OBJECTIVE To compare scapular position and strength and shoulder ROM and strength between Swedish elite tennis players of 3 age categories (<14, 14-16, and >16 years). DESIGN Cross-sectional study. SETTING Tennis training sports facilities. PATIENTS OR OTHER PARTICIPANTS Fifty-nine adolescent Swedish elite tennis players (ages 10-20 years) selected based on their national ranking. MAIN OUTCOME MEASURE(S) We used a clinical screening protocol with a digital inclinometer and a handheld dynamometer to measure scapular upward rotation at several angles of arm elevation, isometric scapular muscle strength, glenohumeral ROM, and isometric rotator cuff strength. RESULTS Players older than 16 years showed less scapular upward rotation on the dominant side at 90° and 180° (P < .05). Although all absolute scapular muscle strength values increased with age, there was no change in the body-weight-normalized strength of the middle (P = .9) and lower (P = .81) trapezius or serratus anterior (P = .17). Glenohumeral internal-rotation ROM and total ROM tended to decrease, but this finding was not statistically significant (P = .052 and P = .06, respectively). Whereas normalized internal-rotator strength increased from 14 to 16 years to older than 16 years (P = .009), normalized external-rotator and supraspinatus strength remained unchanged. CONCLUSIONS Age-related changes in shoulder and scapular strength and ROM were apparent in elite adolescent tennis players. Future authors should examine the association of these adaptations with performance data and injury incidence.
The optimum combination of block codes and receivers for arbitrary channels

A determination is made of the combinations of transmitted block codewords and matching receiver filters that maximize the signal-to-noise ratio at the detector with arbitrary channel impulse response and arbitrary noise spectrum. This permits representing the channel as a set of parallel, uncoupled subchannels with uncorrelated noise; the representation is used to calculate the capacity of an arbitrary block coded, time discrete channel. It is shown that substantial coding gains, compared to symbol-by-symbol processing, can be achieved. The block code used can be concatenated with trellis-coded modulation so that the two coding gains are additive. >
Recruitment of engrafted donor cells postnatally into the blood with cytokines after in utero transplantation in mice.

BACKGROUND We have previously shown that MHC-mismatched fetal liver cells can durably engraft in 45% of nondefective fetal mice, although male donor cells were found in the blood in only 8% of female recipients. We postulated that adult bone marrow stem cells would engraft similarly to fetal liver cells and that postnatal administration of cytokines would recruit donor cells into the peripheral circulation. METHODS Bone marrow from C57BL/6 adult male mice was injected into allogeneic BALB/c or congenic C57BL/6 fetal recipients that were 11-13 days old. Engraftment was tested by quantitative polymerase chain reaction for the Y chromosome in female recipients (0.0001% sensitivity). Recipients were injected at 1-2 years of age with rat stem cell factor (SCF) and human granulocyte colony-stimulating factor (G-CSF) for 7 days and tested for donor cells in the blood. RESULTS The overall engraftment rate (in the blood, spleen, or liver) was 44% in both female allogeneic and congenic bone marrow recipients. Of 49 recipients of bone marrow or fetal liver cells with no evidence of donor cells in the blood before injection, 29 (59%) developed circulating donor cells at some time after cytokine injection for up to 2 months. Twenty-seven of 49 animals were negative in the blood, liver, and spleen before cytokine therapy; 14 of 27 (52%) became positive in the blood after stem cell factor/granulocyte colony-stimulating factor injection. Tolerance to donor skin grafts was not altered by the mobilization of donor cells into the circulation. CONCLUSIONS Adult bone marrow durably engrafts in nondefective mice at a rate similar to that previously obtained with fetal liver. Engrafted donor cells can be mobilized with cytokines into the circulation for up to 2 months even in animals with no evidence of donor cells in the blood, liver, or spleen. Based on these results we estimate that 70-75% of hematopoietically nondefective fetal mice engraft with MHC-mismatched fetal liver or adult bone marrow stem cells.
The Big, the Rich, and the Powerful: Physical, Financial, and Social Dimensions of Dominance in Mating and Attraction

Dominance is a key feature on which romantic partners are evaluated, yet there is no clear consensus on its definition. In Study 1 (N = 305), the authors developed scales to measure three putatively distinct dimensions of dominance: social, financial, and physical. In Study 2 (N = 308), the authors used their scales in a mate-selection paradigm and found that women perceived physical dominance to be related to both attractiveness and social dominance. For both sexes, attractiveness predicted desirability for a one-night stand, whereas attractiveness and agreeableness were predictors of desirability for a serious relationship. In Study 3 (N = 124), the authors surveyed romantic partners in monogamous relationships and found that although aspects of a partner’s dominance—financial for women and social for men—played a bivariate role in relationship satisfaction, agreeableness was the strongest predictor of current and future relationship satisfaction and the only significant predictor of relationship dissolution.
