Horse Anhidrosis Supplements
Equine anhidrosis is the inability to sweat adequately when necessary. This condition is most often seen in horses that live in hot, humid climates. Other signs include increased respiratory rate, elevated temperature, areas of hair loss, and dry and flaky skin. If your horse is not sweating, consider supplements in this category.

What is it?
Anhidrosis or "dry coat" is the decreased ability or complete loss of ability to sweat. Since horses are one of the species that rely on sweating to help keep their body cool, not being able to sweat can cause them to perform poorly or even collapse. Horses that live in hot, humid conditions no matter the age, gender and breed are most likely to gradually develop this condition.What can be done about it?
The underlying cause of anhidrosis remains unclear. Experts believe either something is wrong on the stimulation end (such as with the neurotransmitter adrenaline) or something is wrong on the receptor end (such as decreased numbers of receptors or decreased sensitivity of these receptors). While no treatment exists, there are supplements that support healthy sweating by supplying electrolytes, neurotransmitter precursors and specific herbs.What else do I need to know?
Some horses with anhidrosis regain the ability to sweat when moved from the hot, humid climate to a cooler, drier one yet others don't. Additional tips to help keep horses cool include:- When bringing your horse to a hot, humid climate, allow him to acclimate with 10-14 days of turnout and light work before returning to regular training and showing
- Get your horse "legged up" or conditioned with interval work or distance riding before the hot months so you don't have to work on basic fitness then
- Work your horse during the cooler parts of the day usually morning or evening
- Observe your horse closely during exercise for signs of overheating such as rapid breathing or panting, rapid heart rate and fatigue
- Cool your horse off with water as cold as he will tolerate and quickly scrape it off. Keep reapplying and scraping until his temperature has returned to normal
- Provide cool air with good barn ventilation and fans

Bigger Steal/Bigger Deal?
May 01, 2008 at 12:00 »
Which of our top draft picks was the bigger steal? Which will be the bigger deal?
Mendenhall comes into the league at the tender age of 20, with low tread on his tires, an extraordinarily productive junior season, and at 225# he has the ability to run inside, and the speed to run outside. A decent blocking and receiving back, too. Not real shifty, but adept at finding the hole and getting upfield in a hurry. I had questions about McFadden's transition to the NFL, and had Mendenhall and Stewart as 1a and 1b, the complete backs. Could have and should have gone top 15. As much as the Steelers have and continue to rely on their halfbacks, Mendenhall could have a very nice career here, even if he splits time early on with Parker.
Sweed looked to be the nation's top receiver going into his senior year, but then suffered the wrist injury. Even with that, he was one of the top three receivers in the draft, and could well turn out to be the best. Has a few refinements to make, but has size and speed comparable to Burress. Is described as driven, he'll have some pressure taken off him by the presence of Ward and Holmes on the field. Will soon be part of a fierce receiving threesome, and given the fact that Ward and Holmes have battled injury, Sweed could assert himself as a cornerstone of the passing game sooner than expected. Thought by most to be a late round 1, early round 2 value.

This is a tough question really. If you look at it from the standpoint of Mendenhall being a top RB in a pretty deep RB draft, being a top 10ish type prospect, and what he brings to the table with his size and abilities; he could be the bigger steal.
Sweed though could contribute more at an earlier time. Sweed, in some circles, was the top WR available in the draft. But the WR talent in this draft was not comparable to the RB, as shown by no WR taken in the first round for the first time since 1990. On the numbers alone, Sweed being a potential first round pick, is the bigger steal getting him at the end of the second round.
I am talking in circles here. I think because it is such a difficult question. In the end, I will go out on the limb and say Mendenhall is the biggest steal of the draft. He has top 10 talent, and the Steelers got him @ 23. Eventually, he will get 20-25 touches per game. Sweed will never see that.
It's a hot night. The mind races. You think about your knife; the only friend who hasn't betrayed you, the only friend who won't be dead by sun up. Sleep tight, mates, in your quilted Chambray nightshirts.

I go back and forth on this one.
I remember watching Mendenhall at Illinois and thinking that when he declared, he'd be top 10. He will get more touches, and if he can bring some better balance to the backfield, grind out clock-killer drives, that's what we really need.
But Sweed could provide that big passing punch that's been missed since Plax, despite adding Miller and Holmes. The passing game has been too fitful, inconsistent. If Sweed pushes that part of the offense to where Ben just drives the field at will, that's also something we really need.
Well, those things plus blocking...

Interesting question.
I think Sweed is easily the "bigger steal." While most had RM pegged to go somewhere in the first half of R1, he still ended up being a first round pick...just a later one. Yeah, he slipped a couple of pegs, but not really that much.
Sweed, OTOH, was considered by most to be a R1, maybe early R2,
at worst
, pick. For him to be available almost a full round later than expected, well, to me that equates to the bigger steal and best value.
Now, which guy will end up making the biggest deal (i.e. impact)? I'm not really sure. At this point, I think you can make a pretty good case for either.
Personally, I think it'll boil down to injuries and playing time. As in, which guy will have a starter get hurt who's ahead of them on the depth chart that will make getting significant PT easier. If WP goes down again, I could see Mendenhall stepping in and running wild. If Ward pulls up lame for 2 or 3 games and Sweed gets pushed into a starting role, I could see him having a breakout game or two.
Speaking of Ward, I wonder what his deal is with these moves. He wasn't too crazy about Ben asking for WR help as I seem to remember him kinda taking it as a dig towards the current crop...Wilson getting the axe may have mitigated his feelings on that issue a bit. But, as much as I like the dude, he is an overly sensitve one and a bit of a whiner when things don't completely go his way. Maybe he sees this move as "the writing's on the wall," dude, because honestly, I can't see him playing out his deal after this year for what his cap cost will be in '09. In '08, I think they're lookin' at 6 and change and I seem to recall it jumping to 8 and change next year. He'll undoubtedly have to restructure to be able to retire a Steeler. Not sure he'll be willing to pull a Bettis-type move.

Outstanding Question. As nearly everyone has stated, BOTH seem to fit the bill.
I select Sweed.
Arguements for both sides make sense.
My logic (or lack of) is:
Both players were described by many as first round selections going into the draft. Some even listed both as the number one at their respective position. I resort to my immediate feelings upon seeing the Mendenhall pick.
"Love the player, great selection this late in the first, not a need should have traded down for more picks. Granted there were no O-line worthy of 1.23 remaining in my opinion, if no trade was possible and a skill position was going to be taken should have gone with Sweed. WR is a bigger need, largely due to Hines' age, and most of what I have read had Sweed being the pick between 1.15 and 2.10."
We ended up getting both. Unhappy about the lack of either line being addressed, thrilled that we took potential impact players instead of reaching.
Just hope our O-line is servicable enough to make them both not look like busts.

Outstanding post, Lemon. I think that's about where I am with this, too.
I'm hoping that the ripple effect that was Mahan will go 180 degrees when he's gone. Solidify the guard play, get some decent tackle play, hope they're right about Hills and his drop foot.

I see Sweed as the biggest steal. Although he does have some injury questions, he was definately a late 1st/early 2nd pick. Mendenhall mght be the bigger deal though. He will obviously touch the ball more than Sweed, and will hopefully be the starting RB in 4 years. Still, Sweed will get his chances to impress. At this point you could go with either guy. Lets hope they both rock the house.

and polarization() now returns const Polarization&
* HepMC/IO_GenEvent.h: add a constructor that accepts the filename
as a string.
2008-03-28 Lynn Garren
* HepMC/GenParticle.h: The momentum() method now returns a const
reference to a FourVector instead of a copy of a FourVector.
This change should be backwards compatible.

methods so the user can specify that no beam particles are available.
This fixes a problem with pythia6 input when the user chooses "none".
2008-03-11 Lynn Garren
* src/GenEvent.cc: The GenVertex pointer to the parent event was
not properly moved when the operator= method was used to copy
a GenEvent. That bug is now fixed.
* GenVertex: added protected change_parent_event_ method for swap
as part of bug fix.
* test/testMultipleCopies.cc.in: Add explicit tests for operator=
and swap.

-------------------------- HepMC-2.03.05 --------------------------
2008-02-22 Lynn Garren
* fio/IO_HEPEVT.cc: According to standard HepMC design, all vertices
in an event are expected to contain particles. If, for instance, the
first two particles have no parents, then they should simply not have
a production vertex. However, in at least one instance empty production
vertices were created for the first two particles. IO_HEPEVT now
protects against this.
2008-02-18 Lynn Garren

serial number counter, so the previous solution to retaining
consistent particle ordering within a vertex had to be revisited.
* IO_GenEvent: Replace the temparary particle map with TempParticleMap.

2005-04-27 Matt Dobbs and Giorgos
* src/IO_HERWIG.cxx implemented a bug fix suggested by borut,
which keeps the remapping of daughters/motherrs from going "over
the end" on herwig events (was noticed in the tauola events for
rome DC).
2004-08-04 David Quarrie <firstname.lastname@example.com>
* cmt/requirements: Change dependencies on CERNLIB and CLHEP
to AtlasCERNLIB and AtlasCLHEP to avoid name clashes
-------------------- HepMC-01-02-19 ----(gcc 3.2 compatible)---------
2004-04-22 Matt Dobbs <firstname.lastname@example.com>
* src/IO_HERWIG.cxx (HepMC): fixed bug reported by Hinchliffe in
IO_HERWIG wherein (for the special case of min bias events only)
number of entries in HEPEVT was being zero-ed by the IO_HERWIG
class. Added extra protection in HEPEVT_Wrapper for this as well.
-------------------- HepMC-01-02-18 ----(gcc 3.2 compatible)---------
2004-03-27 Matt Dobbs <email@example.com>
Removed the #define statements that allow backwards compatibility
with gcc 2.95, and specialized the 3.2 compliant iterators to be
forward iterators such that they work properly with std
Thanks to Ulrik Egede for pointing this out.
* HepMC/GenVertex.h, .cxx HepMC/GenEvent.h, .cxx: changed
for standard
compliance, and removed #define statements.
* HepMC/IO_Ascii.h,.cxx: changed open_mode to openmode for standard
compliance, and removed #define statements.
2003-12-17 David Rousseau <email@example.com>
* cmt/requirements: remove HepMC_libraries
2003-10-22 Matt Dobbs <email@example.com>
* src/GenEvent.cxx and lots of other files + latex documentation.
REmoved any mention of units--- GeV, MeV etc, since HepMC merely
accepts whatever is put in. I do this because, though HEPEVT has
used GeV/mm, ATLAS plans to use CLHEP units of MeV/mm.
2003-10-15 Matt Dobbs <firstname.lastname@example.com>
* src/GenParticle.cxx (HepMC): added a default constructor for
GenParticle as requested by Giorgos S.
-------------------- HepMC-01-02-14 ----(gcc 3.2 compatible)---------

-------------------- HepMC-01-02-10 ----(gcc 3.2 compatible)---------
2003-03-03 Matt Dobbs <email@example.com>
* HepMC/GenVertex.h: added extra ifdef statement to allow
compilation on gcc 3.2. (forward_iterator and open_mode problems).
* HepMC/IO_Ascii.h: as above.
* src/IO_Ascii.cxx (HepMC): as above.
2003-01-17 Matt Dobbs <email@example.com>
* src/IO_PDG_ParticleDataTable.cxx (HepMC): if the PDG table does
not exist, we abort, rather than just returning false.
-------------------- HepMC-01-02-04 ----(5.0.0)------------
2002-11-04 Matt Dobbs <firstname.lastname@example.com>
* src/GenEvent.cxx (HepMC): set_barcode(particle, barcode),
set_barcode(vertex, barcode) Fixed a bug reported by Giorgos S.
For this bug, a user suggests a barcode for a vertex that is
already part of an event... the vertex is inserted in the vertex
map with the new barcode, but HepMC forgets to erase the old
entry... such that the vertex now appears twice in the map. This
is fixed, and the corresponding error for particles is also fixed.
2002-10-31 Matt Dobbs <firstname.lastname@example.com>
* HepMC/IO_HERWIG.h: modified IO_HERWIG to include a switch
(default m_no_gaps_in_barcodes=on) which removes null entries from
Herwig HEPEVT and reshuffles the common block
2002-10-22 Matt Dobbs <firstname.lastname@example.com>
* HepMC/HerwigWrapper6_4.h, HepMC/HerwigWrapper.h: new interface
to HERWIG Version 6.4 is added. There is an example for using it
at examples/example_MyHerwig.cxx. To use this example you will
have to download HERWIG version 6.4 and modify the Makefile to
link it.
* HepMC/IO_HERWIG.h: New class for reading the Herwig version of
the HEPEVT common block is added. READ THE COMMENTS IN THE .h file
carefully before using it!
2002-07-29 Matt Dobbs <firstname.lastname@example.com>
-------------------- HepMC-01-02-03 ----(4.0.2)------------
* src/GenVertex.cxx (HepMC): remove_particle()
* HepMC/GenVertex.h:
removed confusing comment about the use of GenVertex::remove_particle()
in .h file, and clarified the comment in .cxx file.
* src/GenEvent.cxx (HepMC): operator=
bug discovered by <email@example.com>.
Formerly, the GenEvent::operator= method relied on the particles
attached to each vertex to always be in the same order. However,
since the particles are stored in set<>, this is not always true
-- making the results of the operator= method unreliable.
This is fixed by mapping the vertices explicitly.
* src/IO_PDG_ParticleDataTable.cxx (HepMC):
added a line in read_entry that ignores empty lines (previously
empty lines in the pdg data table generated a cerr message).
This change was requested by Davida Costanzo.
2002-03-02 Matt Dobbs <firstname.lastname@example.com>
-------------------- HepMC-01-02-02 ----(3.0.1)------------
* src/GenVertex.cxx (HepMC):
GenVertex::edge_iterator::edge_iterator( .. )
Extra error protection added in the constructor.
Sometimes the edge_iterator fails when we have a vertex with no
in_particles. This never happens in standalone mode, but when ran
with the ATLAS framework, it does happen. New code identifies the
scenario explicitly, and catches the error, which has to do with
the past-the-end value of the edge_iterator.
* test/test_iterators.cxx: new test program added for iterators,
to test for the above problems.
2002-02-19 Matt Dobbs <email@example.com>
* cmt/requirements: added the line
macro_append cppflags "" Solaris " -D__SUNPRO_CC "
to handle Solaris CC 5.2 features.
* HepMC/ParticleDataTable.h:
turns on MISSING_FORWARD_ITERATOR when __SUNPRO_CC is defined.
This defines forward_iterator as iterator
* HepMC/GenVertex.h:
same as ParticleDataTable.h, but also turns on
NEED_SOLARIS_FRIEND_FEATURE when __SUNPRO_CC is defined.
* src/Polarization.cxx (HepMC):
replaced abs() with theta = ( theta>0 ? theta : -theta );
for compatibility with Solaris.
2002-02-15 Matt Dobbs <firstname.lastname@example.com>
-------------------- HepMC-01-02-01 ----(3.0.0)------------
* HepMC/GenEvent.h: bug discovered by <email@example.com> with help
from Paolo and Hong.
The GenEvent::particle_iterator, const_particle_iterator,
vertex_iterator, const_vertex_iterator
had methods like:
bool operator !=(const particle_iterator& a) const
{ return !(**this == *a); }
which doesn't work because you are not allowed to de-reference
the end() iterator [the above coding is a relic of the old
walking iterators which did not inherit from
forward_iterstor, and for which *end() was well
The correct usage is:
{ return m_map_iterator == a.m_map_iterator; }
Note: this does NOT affect the GenVertex::***_iterator's, since
for those iterators *end() is well defined.

-------------------- HepMC-01-02-00 --------------------
( Public Version 1.2 )
User manual, webpage, and public version updated.
The CLHEP names branch, called HepMC-00-00-96-CLHEP, has
been moved to the head of the main trunk in cvs, and commited.
Thus the main trunk is the only development branch.
2002-01-22 Matt Dobbs <email@example.com>
-------------------- HepMC-01-01-12 --------------------
* src/GenEvent.cxx (HepMC): delete_all_vertices()
modified the increment of the vertex iterator when looping over
vertices for deletion.
* src/GenVertex.cxx (HepMC): delete_adopted_particles()
modified the increment of the particle iterator when looping over
particles for deletion.
2002-01-21 Matt Dobbs <firstname.lastname@example.com>
-------------------- HepMC-01-01-07 --------------------
* HepMC/GenEvent.cxx (delete_all_vertices):
Possible bug reported here by ATLfast group. Added extra error
checking, and changed the deleting of the vertices such that each
one is explicitly erased from the map.
2002-01-18 Matt Dobbs <firstname.lastname@example.com>
More changes for Windoes MS Visual C++ compatibility:
* HepMC/PythiaWrapper6_2.h, HepMC/PythiaWrapper6_152.h:
included new wrapper methods like call_pyinit, which hide the
funny syntax necessary to call fortran routines from C++.
* examples/example_MyPythiaWithEventSelection.cxx:
* examples/example_MyPythiaOnlyToHepMC.cxx:
* examples/example_MyPythia.cxx:
* examples/Benchmarks_f77/example_PythiaToLCWrite.cxx:
modified to use the call_*** pythia methods.
2002-01-15 Matt Dobbs <email@example.com>
-------------------- HepMC-01-01-06 --------------------
* Makefile.standalone: updated to use cernlib 2001 and pythia6152
* examples/example_UsingIterators.cxx:
The input file was from the old non-barcodes version, and so
didn't work. Replaced it with a proper input file.
These changes suggested by Witold Pokorski <firstname.lastname@example.com> from
LHCb to allow for Windows Visual C++ compliance. All of these changes are
fully backwards compatible(!).
* HepMC/GenEvent.h, HepMC/GenVertex.h: change forward_iterator to
simply iterator (which in the STL standard apparently implies
In Visual c++, a for (int i ... ) {} statement does not scope out
the i variable ... so had to modify the code to ensure no
variables were used twice in the same method:
* src/IO_Ascii.cxx (HepMC):
in lines 155, 161, 175 "int i" is repeated
in lines 293, 314, 321 "int i" is repeated
in lines 293, 314, 321 "p" is repeated
* src/IO_HEPEVT.cxx (HepMC):
in lines 59,65,88 "i" is repeated
in lines 118, 129 "p" is repeated
* src/IO_PDG_ParticleDataTable.cxx (HepMC):
in lines 80, 103, 124 "id_i" is repeated
* src/GenVertex.cxx (HepMC):
in lines: 64 and 72; 168 and 178; 195 and 201; 260 and 273;
322 and 331 variable "part" is repeated
* have verified all STL calls for set, map, less, greater, cout,
endl, list, cerr, ios, iostream, flush are properly prefixed with
* HepMC/GenEvent.h: bug fix:
added a std::greater<int> qualifier to the m_map_iterator of the
vertex iterators.
* HepMC/GenVertex.h: bug fix:
made the GenVertex::particle_iterator a friend of GenVertex.
* HepMC/GenEvent.h, HepMC/GenVertex.h:
move all of the friend class declarations
into statements separate from the class declaration, i.e.
class edge_iterator { ... };
friend class edge_iterator;
instead of
friend class edge_iterator{ ... };
Change all std::ptrdiff_t to ptrdiff_t
* HepMC/IO_Ascii.h: ios::openmode changed to ios::open_mode in the
constructor, for compatibility with windows Visual C++.
* Change #include <iostream.h> to #include <iostream>
Note: this will spoil compatibility with HPUX 10.2 CC.
2001-11-29 Matt Dobbs <firstname.lastname@example.com>
-------------------- HepMC-01-01-05 --------------------
* Fix typo in user manual "particle barcodes are positive"
2001-11 Matt Dobbs <firstname.lastname@example.com>
-------------------- HepMC-01-01-04 --------------------
* update user manual to explain barcodes. NO changes to code.
2001-11-10 Matt Dobbs <email@example.com>
-------------------- HepMC-01-01-03 --------------------
* cmt/requirements: jetset74 requirement removed, as requested by
2001-11-04 Matt Dobbs <firstname.lastname@example.com>
-------------------- HepMC-01-01-02 --------------------
* HepMC/GenVertex.h: removed merge_vertex() method.
* HepMC/IO_HEPEVT.h:
removed the merge_vertices possibility, but added a
build_production_vertex possibility to build_end_vertex.
-------------------- HepMC-01-01-01 --------------------
* src/HEPEVT_Wrapper.cxx (HepMC):
new method check_hepevt_consistency() added.
new method zero_everything() added.
2001-11-02 Matt Dobbs <firstname.lastname@example.com>
-------------------- HepMC-01-01-00 --------------------
* src/IO_HEPEVT.cxx (HepMC):
Modified such that the HEPEVT indices are used for the particle
* HepMC/IO_Ascii.h:
Modifed to properly read/write the barcodes and the
GenEvent new data members.
Unique reference numbers called "barcodes" are added as data
members to GenParticles and GenVertices.
They are cross-referenced in GenEvent via a map<int,GenXXX>.
The GenEvent::m_vertices container of vertices is then no longer
necessary, so it is removed.
The GenEvent::particle_iterator and GenEvent::vertex_iterator
are updated to walk over the maps. The iterator change should be
transparent to the user.
Constant versions of both iterators are included.
The old GenEvent::vertex_iterator was a typedef of the set:
typedef std::set<GenVertex*>::iterator vertex_iterator;
The maps get filled via the:
set_barcode( GenXXX* x, int suggested_barcode )
methods, which in turn are called only by the vertex and particle:
* HepMC/GenEvent.h:
New data members and access methods are added for consistency with
the HepUP standard, see hep-ph/0109068
double GenEvent::m_event_scale
double GenEvent::m_alphaQCD
double GenEvent::m_alphaQED
* src/IO_HEPEVT.cxx (HepMC): Fixed some const warnings with the
GenEvent::vertex_iterator usage.
2001-10-11 Matt Dobbs <firstname.lastname@example.com>
-------------------- HepMC-01-00-01 --------------------
* cmt/requirements: changed use CERNLIB v2001 External to use
CERNLIB CERNLIB-01-* External as per r.d.'s request
2001-10-10 Matt Dobbs <email@example.com>
-------------------- HepMC-01-00-00 --------------------
Identical to HepMC-00-03-08. This tag name follows atlas
naming conventions ... increment the major tag when code is NOT
backwards compatible. Since Atlas is moving from tag
HepMC-00-01-12 (old atlas names) to HepMC-00-03-08 (clhep names)
this change is not backwards compatible.
2001-09-05 Matt Dobbs <firstname.lastname@example.com>
------- below this line is tag HepMC-00-03-08 ----------
(clhep names version to be used in atlas. The changes have not
been made in the HepMC-00-01-** branch)
* src/IO_HEPEVT.h (HepMC):
* src/IO_HEPEVT.cxx (HepMC): When inconsistent info between
mother and daughters is found in the
IO_HEPEVT::build_production_vertex method, IO_HEPEVT will no
longer merge_vertex (the 2001-03-29 "fix") by default. In order to
get this behaviour you have to explicitly ask for it with the
IO_HEPEVT::set_merge_vertex_switch() method.
2001-09-05 Matt Dobbs <firstname.lastname@example.com>
* cmt/requirements: added to the CLHEP names branch (its just a
direct copy of what is in the trunk ATLAS names).
2001-07-17 Matt Dobbs <email@example.com>
(note: HepMC-00-01-24 is an accidental tag which should be ignored)
----- below this line is HepMC-00-01-23, HepMC-00-03-07 -----
* src/GenVertex.cxx (HepMC):
GenVertex::vertex_iterator::follow_edge_() added extra error
checking for the very special-rare case where a particle might
point to the same vertex for both production and end.
Meant to handle Ian H.'s bug of 02 Jul 2001
2001-06-28 Matt Dobbs <firstname.lastname@example.com>
-------------------- HepMC-00-03-06 --------------------
* examples/GNUmakefile.in:
updated the makefile to link to cernlib 2001 version of pythia.
This involves a change -lpythia6136 to -lpythia6152 -lpythiad
Note that for xample_MyPythiaWithEventSelection.cxx 1/100 or
36/1000 events pass cuts (with 6.136 it was 3/100 or 37/1000).
* HepMC/GenParticle.h: now has a parent_event() access method,
which returns the parent_event of the particle's container
vertex's event.
2001-06-27 Matt Dobbs <firstname.lastname@example.com>
---> Make the Vertex know which event it in in. <---
* HepMC/GenVertex.h: added private data member m_event, public
access method parent_event() and protected access method
set_parent_event, which is only to be used by GenEvent. Thus
GenEvent is made to be a friend of GenVertex.
* HepMC/GenEvent.h, src/GenEvent.cxx (HepMC): added logic to
GenEvent::remove_vertex and GenEvent::add_vertex. The vtx's
m_event pointer is set to point back to the event.
* HepMC/ParticleData.h:
* HepMC/GenEvent.h:
* HepMC/GenParticle.h:
* HepMC/GenVertex.h: made method counter() protected. It was never
intended as public, merely as a method for detecting memory
leaks. If no-one complains (they shouldn't, it was commented
"temporary for debugging") I'll remove it entirely later.
2001-03-29 Matt Dobbs <firstname.lastname@example.com>
* src/IO_HEPEVT.cxx (HepMC):
When m_trust_mothers_before_daughters=0, the vertex position is
now filled. In ISAJET sometimes disjoint vertex structures exist,
in this case a merger of vertices is done, which accounts for it.
* HepMC/GenVertex.h:
* src/GenVertex.cxx (HepMC):
Added a void merge_vertex_contents( GenVertex* v_in );
method which takes all the contents of v_in and places it in
the vertex. It does not delete v_in, nor does it remove
v_in from an event.
It will mainly be used by IO_HEPEVT, but it is forseen that users
may want to use it when reducing the overall size of the event
(deleting intermediate vertices) such as will be done by atlas.
2001-02-28 Matt Dobbs <firstname.lastname@example.com>
* Makefile.standalone:
HepMCdir = $(shell pwd)
instead of
HepMCdir = /afs/cern.ch/user/m/mdobbs/HepMC/myCheckoutV1.01
for better portability.
* src/GenVertex.cxx (HepMC): added extra protection to the
GenVertex::edge_iterator::edge_iterator constructor to give
sensible result for the special case when a vertex has incoming
particles, but none outgoing and the user requests a children
iterator. The old version would have
m_set_iter points to m_particles_in.begin() and so the first
dereference might be wrong.
* HepMC/IO_HEPEVT.h: Two new switches are added to give more
flexibility in handling the possible inconsistencies arrising
from the bi-directional pointers in HEPEVT. The switches are:
bool m_trust_mothers_before_daughters;
bool m_print_inconsistency_errors;
which are described by comments in the code. Also makes minor
changes to src/IO_HEPEVT.cxx
* HepMC/Typedef_Version0names.h:
This header file added. It contains typedef statements which
should allow the new version 1.XX class names to be used with code
written with the old version 0.XX class names.
If the user wants to take advantage of these typedefs he needs to
define type variable HEPMC_SHORT_NAMES in his compiler options as
follows: -DHEPMC_SHORT_NAMES
or in his code using #define HEPMC_SHORT_NAMES
Note that since the header file names also changed, this ALSO
requires changing the include statements in the user code.
* doc/latex_user_manual/physicist_visualization.eps
fixed a mis-labelling in this figure... the labels were all
shifted and intermingled... its now right. Unfortunately
the mislabelled version appears in the CPC publication.
also affects doc/latex_user_manual/HepMC_user_manual.ps
Everything below this line corresponds to Version 1.01
2001-01-11 Matt Dobbs <firstname.lastname@example.com>
* examples/example_UsingIterators.cxx:
Changed the class IsFinalState such that a particle must have no
end vertex AND have status==1 to be considered stable.
Does not effect package, only this specific example.
* HepMC/IO_BaseClass.h:
Bug reported by Lynn Garren
"There appears to be a problem with const-ness in HepMC/IO_BaseClass.h.
I have made the following changes in order to compile HepMC 1.0
with g++.
virtual const GenEvent*& operator<<( GenEvent*& );
virtual GenEvent*& operator<<( GenEvent*& );
virtual const ParticleDataTable*& operator<<( ParticleDataTable*& )
virtual ParticleDataTable*& operator<<( ParticleDataTable*& )
In other words, I have made the const-ness match."
These changes are implemented by Matt in the atlas repository.
* HepMC/HEPEVT_Wrapper.h:
Bug reported by Andreas Dell'Acqua
There methods were returning 0 when exactly one parent exists. This
caused the number_children and number_parent methods to return 0
every time there was exactly 1 parent/child. This error caused
major problems in the IO_HEPEVT class, with the end result that
the HEPEVT graphs were interpretted incorrectly [all particles are
correctly interpretted, but their relationships are incorrect for
the case where a particle has exactly ONE mother: in this case the
particles appeared as orphans.]
This bug was
introduced in version HepMC-00-00-94, so it has been present for
some time. This fix is for HEPEVT_Wrapper::last_child():
// Returns the Index of the LAST child in the HEPEVT record
// for particle with Index index.
// If there is only one child, the last child is forced to
// be the same as the first child.
// If there are no children for this particle, both the first_child
// and the last_child with return 0.
// Error checking is done to ensure the child is always
// within range ( 0 <= parent <= nhep )
* src/IO_HEPEVT.cxx (HepMC):
only comments in IO_HEPEVT::build_particle have changed. No change
to code.
Everything below this line corresponds to Version 1.0
2000-11-10 Matt Dobbs <firstname.lastname@example.com>
GeneratorEvent --> GenEvent
Particle --> GenParticle
Vertex --> GenVertex
user manual and online documentaion are updated to reflect this.
* HepMC/PythiaWrapper6_152.h:
A new wrapper for Pythia 6.1 is created to replace the old Pythia
5.7 wrapper. It works with the versions of Pythia in both
CERNlib2000 and CERNlib2001 (versions 6.136 and 6.152 and probably
any Pythia 6).
A pointer file:
* HepMC/PythiaWrapper.h:
is created so the used doesn't have to worry about pythia version
numbers. A test file is located at:
* test/test_PythiaWrapper.cxx
All examples are updated to use Pythia 6.
2000-11-09 Matt Dobbs <email@example.com>
* HepMC/WeightContainer.h:
Created this class to house the weights in the vertex and event
classes. It is just an interface to std::vertex<double>.
The vertex class is modifid to use this. Required changes to:
* HepMC/Vertex.h:
* src/Vertex.cxx:
* src/IO_Ascii.cxx (HepMC):
Everything below this line corresponds to Version 0.94
2000-07-05 Matt Dobbs <email@example.com>
* HepMC/HEPEVT_Wrapper.h: Completely new wrapper for HEPEVT_Common
is implemented. This wrapper treats the common as a series of
bytes and interprets them "on the fly". The user can set the size
(in bytes) of the integer and real numbers to be interpretted from
HEPEVT, and also the total number of entries in HEPEVT. This
allows the user to interface to two applications which use
different HEPEVT definitions.
Benchmarks: 1000 events pythia only 34 seconds.
1000 events Pythia+HepMC(using this new wrapper) 40s
on my particular machine. (extra time is 6 seconds.) Compare this
to the extra 5 seconds reported in the HepMC user manual for the
old HEPEVT wrapper ... so the difference is small compared to the
old wrapper considering the added functionality.
(all examples have been tested and they Run!)
* HepMC/HEPEVT_Common.h: Deleted, this common is now defined
inside HEPEVT_Wrapper.h
* src/HEPEVT_Wrapper.cxx (HepMC): This file is created since it is
necessary to instantiate the static members of HEPEVT_Wrapper in a
.cxx file.
* Makefile.Standalone: modified to build src/HEPEVT_Wrapper.cxx into
the HepMC library
* HepMC/IO_HEPEVT.h: Comment modified only so as to treat
HEPEVT_Wrapper consistently.
* examples/example_MyPythiaWithEventSelection.cxx: Modified to use new
* examples/example_MyPythia.cxx: Modified to use new
* examples/example_MyPythiaOnlyToHepMC.cxx (main): Modified to use new
* PACKAGE: added linkset HepMC -lib:HepMC
(Modified GNUmakefile.in to use libHepMC.so as HepMC linkset)
2000-07-04 Matt Dobbs <firstname.lastname@example.com>
* examples/GNUmakefile.in: $(top_srcdir) replaced by
* GNUmakefile.in (libHepMC.so_SRC): The location of src .cxx files
is now explicitly specified with $(top_srcdir)/src/*.cxx
This makefile now builds oth a shared library libHepMC.so and
libHepMC.a (requested by Ian H.)
* the initpydata.f routine is no longer compiled into the the
HepMC library, but is still packaged with the other routines.
The user needs to link to it explicitly. See the GNUmakefile.in
in the examples directory for an example of how to do this.
(requested by Ian H.)
* ./src is replaced with $(top_srcdir)/src everywhere in the
Files changed this time:
GNUmakefile.in, examples/GNUmakefile.in, Makefile.standalone,
2000-05-18 Matt Dobbs <firstname.lastname@example.com>
* HepMC/IO_BaseClass.h: There is now a fill_next_event method.
- bool fill_next_event( GeneratorEvent* evt ) is a new abstract method
which fills the passed event, and also returns true if successful.
- GeneratorEvent* read_next_event() is now make concrete. it
creates a new event, fills it using the above abstract method,
and returns the event
This change is backwards compatible since the method
read_next_event() has identical behavior.
Identical changes are made for the methods:
- bool fill_particle_data_table( ParticleDataTable* pdt )
- ParticleDataTable* read_particle_data_table()
The methods are updated [ i.e. GeneratorEvent* read_next_event()
is changed to bool fill_next_event( GeneratorEvent* evt ), etc. ]
- IO_HEPEVT.h
- IO_Ascii.h
- IO_PDG_ParticleDataTable.h
- IO_HEPEVT.cxx
- IO_Ascii.cxx
- IO_PDG_ParticleDataTable.cxx
(This change requested by Ian Hinchliffe and Marjorie Shapiro.)
2000-04-24 Matt Dobbs <firstname.lastname@example.com>
* HepMC/HEPEVT_Wrapper.h: set_momentum and set_position now
properly cast input doubles as type HEPEVT_Precision,
previously they were hardwired as cast to double, this
meant writing to real*4 hepevt would fail.
Everything below this line corresponds to Version 0.91
2000-04-11 Matt Dobbs <email@example.com>
* doc/latex_user_manual/HepMC_user_manual.tex: User manual is
updated to replect changes since V0.9
- HEPEVT and position in [mm]
2000-04-06 Matt Dobbs <email@example.com>
* examples/example_MyPythia.cxx
* examples/example_MyPythiaOnlyToHepMC.cxx
* examples/example_MyPythiaWithEventSelection.cxx:
By commenting out the initpydata call (which may be required on
some systems to initialize the Pythia PYDATA block data as
external) the MyPythia examples now run on HPUX (and still on
Linux). Have not tested other platforms.
* Makefile: HPUX with gcc requires the -lf library which contains
the fortran intrinsic function.
2000-04-05 Matt Dobbs <email@example.com>
The changes below will have no effect on the user or package, they
just serve to remove warnings when compiling.
* HepMC/Vertex.h: 313:342:364: warning: unused parameter `enum
::HepMC::IteratorRange dummy_range' (all dummy range parameters
now appear as particles_end( IteratorRange /* dummy_range */ ) )
* src/IO_Ascii.cxx (HepMC): 506: warning: ANSI C++ forbids
variable-size array `c' (the array is now declared as char* c =
new char[key_length +1]; and deleted before returning)
* HepMC/IO_PDG_ParticleDataTable.h: 53: warning: control reaches
end of non-void function read_next_event()
(this is a dummy function anyway -- return 0)
* HepMC/IO_HEPEVT.h:55: (as above)
* src/Flow.cxx (HepMC): 26: warning: default argument given for

* HepMC/IO_PDG_ParticleDataTable.h: 56: (as above)
* HepMC/ParticleDataTable.h: 155: warning: suggest parentheses
around assignment used as truth value (done)
* src/IO_Ascii.cxx (HepMC): 37: warning: default argument given

* HepMC/Flow.h:21: warning: multiline `//' comment
(added space after \ to remove compiler warning)
* HepMC/Particle.h: removed =0 in the inline declaration
inline void Particle::set_flow( int code_index, int code = 0 )
(caused warning).
2000-04-04 Matt Dobbs <email@example.com>
* HepMC/HEPEVT_Wrapper.h: HepMC/HEPEVT_Common.h:
replace the classes HEPEVT_BaseClass.h HEPEVT_Double2000.h
HEPEVT_Double4000.h HEPEVT_Real2000.h HEPEVT_Real4000.h
Using different classes for each of the HEPEVT common block
varieties proved very troublesome - users had trouble and 4
similar classes were being maintained. The new version uses only
static methods and cannot be instantiated (logical since it has
no data members). The HEPEVT common block is contained in the
HepMC/HEPEVT_Common.h header. The precision and number of entries
is specified using #define commands, default is double precision,
2000 entries. The user will see only one change - the IO_HEPEVT
constructor now has no arguments, so he need not define the
any HEPEVT_XXX class. He may need to set the precision and number
of entries. See the header for instructions, and
examples/example_MyPythia.cxx for an example.
example_MyPythia.cxx, example_MyPythiaOnlyToHepMC.cxx,
example_MyPythiaWithEventSelection.cxx are modified to take this
into account.
* HepMC/IO_HEPEVT.h: This class now extracts information from the
fortran HEPEVT common using HEPEVT_Wrapper instead of having to
pass it a class which inherits from the obsolete HEPEVT_BaseClass.
2000-04-03 Matt Dobbs <email@example.com>
* HepMC/PythiaWrapper5_720.h: Credit for writing the wrapper is
to Silvia Resconi.
Inclusion of HEPEVT wrapper header file is not necessary --- hence
2000-03-31 Matt Dobbs <firstname.lastname@example.com>
* HepMC/ParticleData.h: clifetime is now represented in [mm]
instead of [cm] ... previously HepMC had internal inconsistencies
in this --- it claimed to use [cm], but sometimes used [mm] (as
when it read from HEPEVT, and othertimes used [cm] (as when it
transformed a width into a lifetime. Now all is consitent and [mm]
is used everywhere as it should be.
* HepMC/Vertex.h: src/ParticleData.cxx:
Changed comments which say clifetime is in [cm], to say
clifetime is in [mm].
* Makefile (CLHEPdir):
CLHEPdir = /afs/cern.ch/sw/lhcxx/specific/Linux/CLHEP/pro
CLHEPdir = /afs/cern.ch/sw/lhcxx/specific/@sys/CLHEP/dev
to make it platform independent for CERN users.
And some cosmetic changes to the Makefile.
* HepMC/IO_BaseClass.h:
Using the compiler options -ansi -pedantic cause this error:
no match for `::HepMC::IO_Ascii & << ::HepMC::GeneratorEvent *&'
Even though it recognizes:
operator <<(::HepMC::IO_BaseClass &,
const ::HepMC::GeneratorEvent *&) <near match>
as the "best <near match>".
To fix this I make operator<<, operator>> members of the
IO_BaseClass rather than friends, and I add versions where the
argument of operator<< is not constant.
This will not affect users in any way (unless they were using
these compiler options, in which case HepMC didn't work anyway...)
2000-02-16 Matt Dobbs <email@example.com>
* GeneratorEvent.h: set_signal_process_vertex() modified to ensure
that any vertex specified as signal process is ALSO in the
m_vertices set.
* This change log documents changes since Version 9 of HepMC was
"released" February 11, 2000

Why are Citizens being attacked?
Nothing in this world is more alarming then the fact that United States Citizens are being attacked
and done harm by the Homeland Security Satellite Program. I was attacked while in Ohio early
last year, March and April, after some traveling to Oklahoma, and on to Amarillo, Texas.
Apparently, this torturing started before my trip West, for I suffered substantially, prior to
that time, not realizing what was happening to me. Throughout 06-07 Fall-Winter, October until
the time I went on my journey West in March, I suffered an agonizing experience of an equal
consequence. I consider it much more evil and more deadly, for it was done within my home, day
and night, while sleeping, while eating, while using the bathroom.
I'm sure you are extremely hesitant about even thinking such a thing is happening. Yes,
this was my first thought when Satellites defense technology came to mind, "Is it possible?"
"Could it be?", someone like me, being under surveillance, being attacked by such high tech
equipment?" No Way! I thought. But, after weeks of suffering its affect, I discovered truly,
satellites are involved. Of course, it wasn't an overnight revelation.
Sadly, nearly all affected citizens have no idea as to why they are in throbbing pain—only a
few, those involved would understand such uncivilized tactics. Spying and harm is going on today
and now. Are you willing to believe such evil, as it happens, is going on in my home? The End.

Why does the A10-5800K performs so poorly?
I checked some directx benchmarks on internet and saw that it should perform better than the hd4000 and the hd4600.
I found why: the benchmark here is done with the open source driver.
I think adding a line for the A10 and the catalyst driver would have been appropriate.

Comments:This bait is fabulous,especially if you put a little foam in his hollow body the bait will suspend on a Carolina rig about 2 feet off of the bottom. I caught 20 9lb bass in one day on this bait, I highly recommend it!

Not that long ago, doctors and nurses would write notes in a patient's chart — often a sheaf of papers fastened to a clipboard — during an office visit. These notes then would be added to the patient's ever-expanding medical file, which was physically stored on the premises. Until the digital age, there was no other way to store a patient's medical record.
But that was then.
Today, more and more patients can expect to see computers instead of clipboards when they hop onto the exam-room table, thanks to the adoption of health information technology (HIT) by U.S. health care providers and hospitals.
By 2014, it is estimated that the majority of hospitals, doctors' offices, and medical centers nationwide will store health information electronically.
An electronic health record (EHR), also called electronic medical record (EMR), is a computerized collection of a patient's health details. But it's more than just that — it's a new way of storing and organizing patient information. Like hospital charts, EHR patient files are divided into sections where health care providers and staff can find the information they need to provide patient care or perform administrative tasks.
Information stored within an EHR can include a patient's medical history (including immunization status, test results, and growth and development records), health insurance and billing information, and other health-related data.
Because it's stored digitally, the information can be shared easily among a patient's various health care providers within a facility, and can be quickly sent from one facility to another if a patient finds a new health provider.
Most hospitals have their own unique EHR databases that are set up to be accessible from every computer. To open a patient's health record, a doctor, nurse, or other health care provider would log into the system with a username and password or thumbprint identification.
Providers also can access information remotely (such as from an off-site computer) by logging into their work's network system via the Internet and accessing the EHR. Systems are directly accessible over the Internet, too.
Everyone knows the jokes about doctors' unreadable handwriting. But the advantages of EHRs go way beyond issues of legibility. EHRs also can:
Yes. A federal law called the Health Insurance Portability and Accountability Act (HIPAA) identifies who's allowed access to medical records. Specifically, HIPAA protects:
So you shouldn't worry if, for example, your nosy neighbor happens to work in the same hospital where your child receives treatment. HIPAA bars anyone from snooping into patient records. And any attempt to access classified information would likely trip an alarm within the institution's computer's system and can be traced.
Also, hospital employees only have access to the parts of the EHR required to do their job. This helps keep the rest of the record secure and private. And after a user's session has been inactive for a few minutes, the system automatically logs off to protect others from viewing the information.
In addition, a provision of the law, called the Security Rule, specifically addresses the security of EHRs by establishing national standards for protecting certain health information that is stored or transferred in electronic form. Any provider who transmits health information electronically is required by law, for example, to have safeguards (hardware, software, etc.) in place to limit access to that information to those permitted to see it.
Yes. Just like with old-fashioned paper charts, you have the right to view your child's medical information. Because EHR technology is still in its infancy, not all health care facilities provide ways for patients and their families to log into the system, but some do.
If your health care provider offers this service, ask what's required of you. You'll probably need to register into the system and provide a username and password. Things like your child's medical history, family history, allergies, and prescription medications will be viewable, but any physician notes, test results that haven't been reviewed, and most psychiatric evaluations will be hidden. Additionally, if your child is a teenager, it's likely that more areas will be hidden to protect your child's privacy.
If your health care facility does not yet offer access to EHRs, you still can request a paper or digital (CD-ROM) copy of the file. Digital copies can be stored on software known as a Personal Health Record (PHR), either on your home computer or online. Some online PHRs are free, while others have initial setup fees and monthly maintenance costs.
With these accounts, you'll be responsible for keeping your records up to date. While this may take some work, it's a good way to make sure that all of your child's medical information is in one place. Patient-owned records are especially useful for managing the care of kids with chronic conditions and those who receive care at multiple institutions.

I chatted by phone the other day with Sen. Elizabeth Warren for a column I'm working on, and before I let her go, I suggested she read "The Rise of the Warrior Cop" by Radley Balko. I'm not sure she will – she said she's spending her vacation reading up on the history of government mortgage loan guarantee programs – but she sounded interested.
It's a recommendation I've been pushing on almost everyone I meet. But since I understand folks have their own summer reading list, Balko wrote a condensed version, which appeared in the Wall Street Journal the other day. In it, he brings up the name that haunted my thoughts from the first page of the book to the last:
In my own research, I have collected over 50 examples in which innocent people were killed in raids to enforce warrants for crimes that are either nonviolent or consensual (that is, crimes such as drug use or gambling, in which all parties participate voluntarily). These victims were bystanders, or the police later found no evidence of the crime for which the victim was being investigated. They include Katherine Johnston, a 92-year-old woman killed by an Atlanta narcotics team acting on a bad tip from an informant in 2006; Alberto Sepulveda, an 11-year-old accidentally shot by a California SWAT officer during a 2000 drug raid; and Eurie Stamps, killed in a 2011 raid on his home in Framingham, Mass., when an officer says his gun mistakenly discharged. Mr. Stamps wasn't a suspect in the investigation.
